BACKGROUND OF INVENTION
Field of Invention
[0001] This invention relates to a laundry press finishing device, which is, in particular,
one preferably formed to press finish laundry with the surface like such as sheets,
table clothes, handkerchieves and like.
Related Art of Invention
[0002] As this type of conventional devices, there has already been provided with the laundry
pressing finishing machine, as described in
U.S. Patent No. 4,280,290, for example, which comprises a lower iron on which the laundry is mounted and an
upper iron for depressing the upper surface of the lower iron to press finish the
laundry.
[0003] Conventionally, in this type of prior art device, when a long-sized laundry such
as sheets was to be press finished, it was necessary to repeat such operations as
one in which at first a part of the sheets was pressed with the upper iron and then
the position of the sheets was displaced and set again and after this work, the upper
iron was lowered again to press against the sheets.
[0004] Accordingly, in the case that this type of laundry was to be press finished with
the prior art pressing machine, there occurred some problems that it required a tremendous
amount of labor and time.
[0005] Additionally, as described above, since it was necessary to lift up or lower the
upper iron several times, there could easily occur some troubles that an operator'
s head or hands were held by accident with the upper iron and got scaled in touch
with the upper iron.
[0006] In addition, the prior art pressing machine showed a poor working efficiency and
also a poor convenience in use when a pressing work for the sheets was started because
the operator usually could not move away from the machine and could not perform other
works.
[0007] Further, this type of prior art pressing machine frequently showed a case in which
the upper iron was installed near a position where the operator stood for setting
the laundry at the lower iron. Accordingly, the prior art machine sometimes showed
a dangerous state in which the operator's head or the like got scaled with the upper
iron when the operator set the laundry on the lower iron.
SUMMARY OF INVENTION
[0008] In view of some circumstances as found in the prior art pressing machine, this invention
has been invented.
[0009] Accordingly, a technical problem to be resolved by this invention consists in enabling
the plane laundry such as the sheets or handkerchief or the like to be press finished
safely without any troublesome work.
[0010] In order to resolve the aforesaid problems, this invention provides such technical
means as follows.
[0011] That is, as shown in FIG. 1 and the like, this invention comprises the lower iron
for use in mounting the laundry and the upper iron for depressing an upper surface
of the lower iron to press finish the laundry, in which the aforementioned lower iron
is formed into a belt conveyor shape with an iron main body for accepting a press
pressure of the upper iron, an annular moving cover covering the outer peripheral
surface of the iron main body, endless transmittance members integrally formed with
the moving cover and formed into an annular shape and transmittance wheels over which
the endless transmittance members are applied and wherein there is provided a driving
means for rotating the transmittance wheels only by a predetermined length in response
to a control signal got from a controller every time the aforementioned upper iron
is opened after the pressing operation to transfer the cover in a rearward direction,
the laundry is sent by this driving device in a rearward direction together with the
moving cover and press finished with the upper iron.
[0012] In this invention, although the driving device is usually constituted by a rotating
force generating machine such as an electric motor and the like, it may also be applicable
that this driving device is constituted under a combination of a cylinder and a device
for changing a linear motion of a rod in the cylinder into a rotating motion. The
transmittance member is constituted by a belt or a chain, for example and the controller
is constituted by a microcomputer and a sequencer. The predetermined length defined
in this case is meant practically to be the same one as a width of the iron surface
of the upper iron in a forward or rearward direction or a length slightly shorter
than that. This value is set for preventing a part not to be pressed in the laundry
from being generated when the laundry is sent intermittently and pressed with the
upper iron.
[0013] Additionally, although the transmittance wheels in this invention are arranged at
the front and rear positions of the lower iron, it may also be applicable that they
may be provided with a tension wheel, for example. In addition, this invention may
also be applicable in such a way as that it is combined with a device for supplying
the laundry to the upper surface of the lower iron or the lower iron is formed into
a vertical elongated shape as seen from its side surface to cause the laundry to be
sucked to the moving cover, for example, then the laundry to be sent from below toward
the upper surface of the lower iron and the laundry to be press finished with the
upper iron.
[0014] This invention is preferably to arrange that a length of the upper surface of the
lower iron in a forward or rearward direction is formed to be longer than a width
of the iron surface of the upper iron in a forward or rearward direction and that
the iron main body is position set at the rear side.
[0015] A reason why this operation is carried out consists in the fact that the laundry
can be set on the upper surface of the lower iron that is faced to the operator and
then its convenience in operation is improved. Additionally, in this case, since the
upper iron becomes to be arranged at the rear side of the device in correspondence
with the iron main body, occurrence of trouble in which the operator's head or hands
are contacted with the upper iron when the operator sets the laundry onto the upper
surface of the lower iron can be reduced more and correspondingly the setting work
can be carried out safely.
[0016] Further in this case, as shown in FIG. 1 etc. this invention comprises preferably
that the upper surface of the lower iron is formed in an upward slant shape from a
front side toward a rear side, an upper surface of the iron main body is formed into
a convex curved shape as seen from a side surface in correspondence with a concave
curved iron surface of the upper iron.
[0017] Since the laundry is sent while being raised, no wrinkle is generated at the laundry,
but the laundry can be sent regularly and correspondingly the laundry can be press
finished in a neat manner. In addition, in accordance with operation, it is possible
to arrange the upper iron at the high position of the rear side of the device and
it can be used more safely.
[0018] In addition, this invention preferably comprises that a feeder device for receiving
the press finished laundry dropped from the rear side of the lower iron and feeding
it to a recovery location is provided and formed.
[0019] By the above device, the press finished laundry can be received easily and quickly.
[0020] Additionally in this case, this invention is preferably to comprise that the feeder
device is formed by a conveyor for feeding the laundry forward and arranged below
the lower iron.
[0021] By the above, one can receive the laundry quickly and easily at the front side of
the device.
[0022] Additionally in this case, this invention is preferably to comprise that the feeder
device is formed into a slide-shape inclined down toward the front side and arranged
below the lower iron.
[0023] By the above device, it make the feeder device to be more simply and low cost service
is gained.
[0024] Further, as shown in FIGS. 9 to 13, this invention is preferably to have a device
for folding back the already press finished laundry dropped from the rear side of
the lower iron in a forward or rearward direction and folding while accepting the
laundry is provided and formed.
[0025] By the above device, it can recover to a long-sized laundry folded over.
[0026] Additionally, as another configuration of this invention, a device shown in FIGS.
14 to 16 can be applied. This invention shown in FIG. 1 is operated in such a way
that every time the upper iron is opened, the laundry is transmitted intermittently
in a rearward direction and press finished. To the contrary, the device of this invention
shown in these figures is operated in such a way that when the laundry is sent to
a location below the upper iron on the first operation and press finished, the laundry
is returned back to the front side and recovered. Accordingly, the device of another
configuration of this invention is suitable for finishing a short plane laundry such
as a handkerchief or the like, for example.
[0027] So, this invention is provided and formed by comprising the lower iron on which the
laundry is mounted and the upper iron for depressing the upper surface of the lower
iron to press finish the laundry;
said lower iron being formed into a belt conveyor shape with the iron main body for
accepting a press pressure of the upper iron, an annular moving cover for covering
the outer peripheral surface of the iron main body, endless transmittance members
integrally formed with this moving cover and formed into an annular shape, and transmittance
wheels over which the endless transmittance members are applied;
length of the upper surface of the lower iron in a forward or rearward direction is
formed to be longer than a width of the iron surface of the upper iron in a forward
or rearward direction and the iron main body is position set at the rear side;
additionally the driving device for rotating said transmittance wheels in a normal
or a reverse direction,
there being provided and formed the driving device for rotating said transmittance
wheels in a normal or a reverse direction, and a control circuit outputting to said
driving device a signal for rotating the transmittance wheels in a normal direction
to send the laundry rearward together with the moving cover so arranging it on the
iron main body before pressing, and for rotating the transmittance wheels in a reverse
direction to return the laundry forward together with the moving cover when a press
finishing is completed and the upper iron is opened.
[0028] In the case of this invention, the configuration of the driving device, the transmittance
members, the transmittance wheels and like is the same as this invention according
to Claim 1 in FIG. 1. The control circuit is structured by the microcomputer and the
sequencer.
[0029] Additionally in the case of this invention, the upper surface of the lower iron is
formed into an upward slant shape from the front side toward the rear side, and the
upper surface of the iron main body is formed into a convex curved surface as seen
from a side surface in correspondence with a concave curved iron surface of the upper
iron is preferred.
[0030] By the above, since the laundry is forwarding on upward slant shape from the front
side, the laundry can be kept in good order without slack so that the neatly press
finishing may be done. Future, by this process, the upper iron can be formed at the
high position at the rear side of the device, so that it can be used much safely in
work operations.
[0031] Additionally this invention, as shown in FIGS. 17 to 21, a set work auxiliary device
for expanding the laundry in rightward and leftward directions and arranging it on
the moving cover is installed in an upper side position of the lower iron and a front
side position of the upper iron is preferred.
[0032] By the above device, set work of wide laundry can be made easily.
[0033] Additionally in this invention as shown in FIG. 22 and like, it is preferable that
the front side of the upper iron is provided with a guard member for preventing an
operator' s hand or fingers from entering below the upper iron.
[0034] By the above member, it can prevent from injure that an operator's hands were held
by the upper iron.
[0035] Additionally in this invention as shown in FIG. 24, it is preferable that members
for preventing a zigzag motion of the moving cover are arranged at both sides of the
lower iron.
[0036] By this member, even if the position of the transmittance wheels and like is got
out of position, it can prevent the zigzag motion of the moving cover and treat laundry
moving to strait.
[0037] Additionally in the case of this invention as shown in FIGS. 7 and 8, the upper iron
is formed in such a way that its lifting-up or descending motion can be carried out
and its rear side can be pushed down and turned around a lateral shaft extending along
a lateral direction as seen from a front side, and a drain pipe for use in flowing
water generated from steam supplied into the upper iron is connected to the rear side
of the upper iron.
[0038] A reason why this state can be obtained consists in the fact that a size of the device
in its forward and rearward direction can be reduced as compared with that of a case
in which the upper iron is turned in a forward or rearward direction because the upper
iron performs a lifting-up or descending motion. In addition, in this case, a reason
for it consists in the fact that a time required for the pressing operation can be
shortened since the operating stroke of the upper iron becomes short. Further, in
accordance with this arrangement, inclination of the upper iron enables water generated
from steam within the upper iron to be drained easily and promptly.
[0039] In the case of this invention shown in FIG. 1, every time the upper iron is opened
in this way, then the laundry is automatically sent to the rear side together with
the moving cover for the same distance as the length corresponding to the forward
and rearward width of the iron surface of the upper iron and is press finished.
[0040] Accordingly, applying this invention enables the long laundry such as the sheets
to be press finished simply, easily and promptly.
[0041] Additionally, since this invention enables many times of moving-up or moving-down
operations of the upper iron occurred in the prior art machine to be completely eliminated,
this invention enables a rate of occurrence of accident such as burn or the like to
be reduced.
[0042] In addition, in the case of this invention, when the laundry is set on the upper
surface of the lower iron, the laundry can be press finished even if the operator
moves away from the front part of the device. Accordingly, in accordance with this
invention, another cleaning operation canbe carried out together with this operation
and it is possible to increase a working efficiency.
[0043] Further, in the case of this invention shown in FIGS. 14 to 16, the laundry can be
sent to a location below the upper iron under one time operation and press finished
and after these operations, the laundry can be returned back to the front side and
the laundry can be restored.
[0044] Therefore, in accordance with this invention, it is possible to make a complete and
safe setting of a short plane laundry such as a handkerchief or the like in particular
at a position spaced apart from the upper iron and perform a simple, easy and prompt
press finishing.

DESCRIPTION OF PREFERRED EMBODIMENTS
[0046] Referring now to the accompanying drawings, preferred embodiment of this invention
will be described as follows:
[0047] The device of this invention shown in FIGS. 1 and 2 is preferable for press finishing
a long plane laundry 1 such as the sheets or a Japanese yukata and the like.
[0048] The device of this invention is provided and formed with the lower iron 2 on which
the laundry 1 such as the above is mounted and the upper iron 3 for depressing the
upper surface of the lower iron 2 to press finish the laundry.
[0049] The lower iron 2 being formed into a belt conveyor shape with an iron main body 21
for accepting a press pressure of the upper iron 3, an annular moving cover 22 for
covering the outer peripheral surface of the iron main body 21, endless transmittance
members23integrallyformedwith thismoving cover 22 and formed into an annular shape,
and transmittance wheels 24 over which the endless transmittance members 23 are applied.
[0050] A pair of front and rear transmittance wheels 24 in this preferred embodiment are
formed.
[0051] The invention of this embodiment, the length of the upper surface of the lower iron
2 in a forward or rearward direction is formed to be longer than a width of the iron
surface 31 of the upper iron 3 in a forward or rearward direction and the iron main
body 21 is position set at the rear side. Additionally, the upper surface of the lower
iron 2 is formed in an upward slant shape from a front side toward a rear side, the
upper surface of the iron main body 21 is formed into a convex curved shape as seen
from a side surface in correspondence with a concave curved iron surface 31 of the
upper iron 3. As shown in FIG. 5, the upper surface of the iron main body 21 is covered
with a cover 213 through a silicone mat layer 211 and a flannel layer 212.
[0052] Transmittance members 23 are formed by belts in this preferred embodiment. As shown
in FIG. 6, the belt acting as each of the transmittance members 23 is provided with
a flannel layer 231 and a cushion material layer 232 and is integrally formed with
the moving cover 22 through these members.
[0053] In addition, as shown in FIG. 4, in the case of this preferred embodiment, a rear
side transmittance wheel 24 of a pair of front and rear transmittance wheels 24 is
formed like a gear at both sides of a shaft 241. In addition, the front side transmittance
wheel 24 is formed like a roller at both sides of a shaft 242.
[0054] Further, as shown in FIGS. 1 and 5 or the like, the moving cover 22 is supported
with a plate 4.
[0055] Further this invention, as shown in FIG. 1, is provided with the driving device 6
for rotating the transmittance wheels 24 just for the length which is shorter than
a width of the iron surface 31 of the upper iron 3 in a forward or rearward direction
in this embodiment, in response to a control signal got from the controller 5 every
time the aforementioned upper iron 3 is opened after pressing operation and sending
the moving cover 22 rearward.
[0056] In the case of this embodiment, the controller 5 is formed microcomputer and the
driving device 6 is formed motor.
[0057] The controller 5 is electrically connected to a sensor 7 (refer to FIG. 4) for use
in detecting the number of rotation of the transmittance wheel 24. Then, the controller
5 is constituted in such a way that when the number of rotation of the transmittance
wheel 24 reaches up to a set value, it may output a stop signal to the driving device
6. The set value is set to three times of rotation in this preferred embodiment.
[0058] Additionally, in the case of this preferred embodiment, the inner side of the lower
iron 2 is evacuated with a suction device 8 (refer to FIGS. 1 and 2 or the like) and
it is formed in such a way that the laundry 1 can be sucked and adhered to the moving
cover 22. This suction device 8 is formed such that its turned-on or turned-off state
can be controlled with a foot switch 81 (refer to FIG. 1).
[0059] In addition, in FIG. 1, reference numeral 9 denotes a feeder device for receiving
the laundry 1 dropped from the rear side of the lower iron 2 and sending it to its
recovering location. This feeder device 9 is formed into a belt-conveyor shape with
a motor 91 and an endless transferring belt 92 and arranged below the lower iron 2.
Further, reference numeral 10 denotes a case for use in collecting the laundry 1.
The laundry 1 is sent to the front side of the device with the feeder device 9 and
recovered at this case 10.
[0060] In addition, the upper iron 3 in this preferred embodiment is formed in such a way
that it can be freely lifted up or lowered. As shown in FIGS. 1 and 7 and the like,
when a cylinder 11 for the upper iron 3 receives a signal from the controller 5, its
rod extends or retracts to lift up or move down the upper iron 3. Additionally, as
shown in FIG. 8, the upper iron 3 is formed such that its rear side can be pushed
down and turned around a lateral shaft 12 extending in a lateral direction as viewed
from the front side of the device. In this figure, reference numeral 13 denotes a
cylinder for use in pushing down the rear side of the upper iron 3. As the rod of
this cylinder 13 extends, the rear side of the upper iron 3 is pushed down and in
turn as the rod is retracted, the rear side is pulled up to cause the upper iron 3
to be arranged in a horizontal state.
[0061] Additionally, as shown in FIG. 1 and FIG. 8 and the like, the upper iron 3 has its
rear side to which a drain pipe 14 for use in flowing water generated from steam supplied
into the upper iron 3 is connected. Steam supplied from a steam supplying pipe 15
(refer to FIGS. 2 and 3) into the upper iron 3 is heat exchanged to cause its temperature
to be reduced and its part is changed intocoldwater. In this invention, this water
is drained through the drain pipe 14 by an operation in which the rod in the cylinder
13 extends to cause the rear side of the upper iron 3 to be pushed down.
[0062] Subsequently, an action of this invention of the preferred embodiment will be described
as follows.
[0063] At first, as shown in FIG. 1 and the like, the operator sets one end of the laundry
1 such as the sheets or the like on the upper surface of the lower iron 2 facing to
the operator and turns on a switch 16 of the driving device 6 (refer to FIG. 2). In
this case, the laundry 1 is sucked against the moving cover 22 by the sucking device
8. When the switch 16 of the driving device 6 is turned on, the motor is driven to
cause the laundry 1 to be sent together with the moving cover 22.
[0064] Then, when the transmittance wheels 24 rotate by three times, the controller 5 outputs
a stopping signal to the motor acting as the driving device 6 and then the motor stops.
With this arrangement, the laundry 1 is sent to the rear side only by an amount slightly
shorter than a width of the iron surface 31 of the upper iron 3 in this preferred
embodiment in its forward or rearward direction.
[0065] Subsequently, the rod in the cylinder 11 for the upper iron 3 extends in reference
to the signal got from the controller 5. With this arrangement, the laundry 1 is pressed
with the upper iron 3 only for a set time. Then, as the set time elapses, a signal
is outputted from the controller 5 to a solenoid valve (not shown) and the solenoid
valve changes over a flow path of the air. Under this operation, the rod in the cylinder
11 for the upper iron 3 retracts and the upper iron 3 is lifted by 50 mm in this preferred
embodiment and moved away from the upper surface of the lower iron 2.
[0066] Next, the controller 5 receives the signal indicating a retraction of the rod in
the cylinder 11 for the upper iron 3 and outputs a driving signal to the driving device
6. With this operation, the motor acting as the driving device 6 is driven to cause
the laundry 1 to be sent together with the moving cover 22.
[0067] Then, as the transmittance wheels 24 are rotated by three times, the motor acting
as the driving device 6 stops with a signal got from the controller 5 and subsequently
the rod in the cylinder 11 for the upper iron 3 extends.
With this operation, the laundry 1 is pressed with the upper iron 3 by a set time
only. Then, as the set time elapses, the rod in the cylinder 11 for the upper iron
3 retracts and the upper iron 3 is opened.
[0068] This invention in this preferred embodiment causes the laundry 1 to be sent intermittently
in a rearward direction only by a little shorter length than a width of the iron surface
31 of the upper iron 3 together with the moving cover 22 and pressed with the upper
iron 3 to finish the laundry 1.
[0069] As to the above, this invention is preferable to form: a controller 5 being provided
with a control part 5a (refer to FIG. 1) outputting to the driving device 6 a signal
for rotating the transmittance wheels 24 in a reverse direction to return the laundry
1 forward together with the moving cover 22 when a press finishing is completed and
the upper iron 3 is opened. By the above, laundry 1 such as handkerchieves and like,
is sent to rearward and pressed by the upper iron 3, and then to be returned to the
front side for easy recovery.
[0070] Additionally this invention is preferable that the feeder device 9 is formed into
a slide-shape inclined down toward the front side.
[0071] In addition, in the case of the aforesaid example, although the laundry 1 is sucked
against the moving cover 22 with the suction device 8, this invention is not restricted
by this arrangement. That is, it may also realized in this invention that the moving
cover 22 is formed with a cloth having several needle-like bristles, for example,
or the plane fastener is arranged at the moving cover to cause a contact friction
between the moving cover 22 and the laundry 1 to be increased.
[0072] Additionally, in the case of this invention, it is of course apparent that the upper
iron 3 may be formed in such a way that it can be turned in a forward and rearward
direction of the device.
[0073] Further, in the case of this invention, it is suffice if the lower iron 2 is formed
in such a way that the moving cover 22 can be circulated and it is not restricted
to such a structure as disclosed in the above example. In addition, the laminated
structure of the iron main body 21 and the transmittance member 23 may also be optional.
[0074] Additionally, as shown in FIGS. 9 to 13, in this invention, it is preferable to provide
and to form
a device 50 for folding back the already press finished laundry 1 dropped from the
rear side of the lower iron 2 in a forward or rearward direction and folding while
accepting the laundry 1. As shown in FIG. 12, this device 50 is formed to be provided
with transmittance belts 53 arranged over an upper side shaft 51 and a pair of front
and rear round bars 52, a motor 54 for driving the upper side shaft 51 to circulate
the transmittance belts 53, a pair of front and rear rollers 57 forming the transmittance
belt 53 into a slant part 55 and a horizontal part 56, and a driving part 58 such
as a cylinder or the like for advancing or retracting the horizontal part 56 in a
forward or rearward direction. The aforementioned slant part 55 is a location where
the laundry 1 dropped from the lower iron 2 is received and brought in a downward
direction and the horizontal part 56 is a location where the laundry 1 is brought
in a forward or rearward direction.
[0075] The aforementioned plural transmittance belts 53 are spaced apart by a predetermined
space in a lateral direction in this preferred embodiment and tensioned under a parallel
state to each other. In addition, between the transmittance belts 53 are arranged
slant plates 59 for use in guiding the laundry 1 to the horizontal part 56.
[0076] As shown in FIG. 9 and the like, the aforesaid round bar 52 is arranged in parallel
with front and rear positions of a pair of right and left elongated plates 60 and
pivotally connected to the plate 60. Additionally, as shown in FIGS. 9 and 11, the
plates 60 are held by a pair of upper and lower rollers 62 arranged inside the raised
supporting plates 61 and installed to be slidable in a forward or rearward direction.
In addition, the plates 60 are connected to the elongated outer plates 63 arranged
outside the supporting plates 61 by a shaft 64. The supporting plates 61 are formed
with slits 65 through which the shaft 64 is passed to extend in a forward or rearward
direction.
[0077] Further, as shown in FIG. 12, the extremity end of the rod in the cylinder acting
as the driving part 58 is pivotally connected near the lower ends of turning members
67 of which upper ends are pivotally connected to the side plates 66. The turning
members 67 are arranged at both rear sides of the horizontal part 56 and connected
by a bar 68 (refer to FIG. 11 and FIG. 13) in such a manner as one in which a motion
of one turning member 67 can be transmitted to the other turning member 67. Then,
the lower end of one turning member 67 and the rear end of the outer plate 63 are
pivotally connected by a shaft 69. In addition, a pair of front and rear rollers 57
are supported by the supporting plates 61. In this case, the rear roller 57 is attached
in such a way that its position can be freely changed in a forward or rearward direction
to enable its tension to be adjusted.
[0078] Next, an action of this preferred embodiment will be described as follows.
[0079] At first, when the transmittance belts 53 are circulated, the laundry 1 dropped from
the rear side of the lower iron 2 is guided from the slant part 55 to the horizontal
part 56 and sent in a forward direction as shown in FIG. 9. Then, as shown in FIG.
12, when the rod in the cylinder acting as the driving part 58 is extended, the turning
members 67 are moved in a rearward direction and the round bar 52, plate 60 and outer
plate 63 are moved together in a rearward direction. With this motion, the horizontal
part 56 is moved back and as shown in FIG. 9, the rear side position of the laundry
1 is arranged.
[0080] Then, when the rod in the cylinder acting as the driving part 58 is retracted, the
turning members 67 move in a forward direction and the horizontal part 56 advances
forward. With this operation, the front side position of the laundry 1 is arranged
as shown in FIG. 10. Thus, repetition of such an operation as above causes the laundry
1 to be folded back by the device 50 and folded.
[0081] Next, referring to FIGS. 14 to 16, one preferred embodiment of this invention according
to Claim 8 will be described. The same members and the same locations as those of
the aforementioned example will be denoted with the same reference numerals and their
detailed description will be eliminated.
[0082] This invention is formed, for example, the lower iron 2 on which the laundry 1 such
as handkerchieves and like of a small width face is mounted and the upper iron 3 for
depressing the upper surface of the lower iron 2 to press finish the laundry 1, and
said lower iron 2 being formed into a belt conveyor shape with the iron main body
21 for accepting a press pressure of the upper iron 3, an annular moving cover 22
for covering the outer peripheral surface of the iron main body 21, endless transmittance
members 23 integrally formed with this moving cover 22 and formed into an annular
shape, and transmittance wheels 24 over which the endless transmittance members 23
are applied.
[0083] The length of the upper surface of the lower iron 2 in a forward or rearward direction
is formed to be longer than a width of the iron surface 31 of the upper iron 3 in
a forward or rearward direction and the iron main body 21 is position set at the rear
side. The upper surface of the lower iron 2 is formed as same as said example, in
an upward slant shape from a front side toward a rear side, the upper surface of the
iron main body 21 is formed into a convex curved shape as seen from a side surface
in correspondence with a concave curved iron surface 31 of the upper iron 3.
[0084] Additionally this invention is formed to comprise, the driving device 6 for rotating
said transmittance wheels 24 in a normal or a reverse direction, and the control circuit
17 outputting a signal for the driving device 6. (refer to FIG. 14).
[0085] Said driving device 6, comprise motor for example. The control circuit 17, realizedmicrocomputer
for example, as shown in flow chart of FIG. 16, is outputting to the driving device
6 a signal for rotating the transmittance wheels 24 in a normal direction to send
the laundry 1 rearward together with the moving cover 22 so arranging it on the iron
main body 21 before pressing, and for rotating the transmittance wheels 24 in a reverse
direction to return the laundry 1 forward together with the moving cover 22 when a
press finishing is completed and the upper iron 3 is opened. In the case of this invention,
count of rotate of the transmittance wheels 24 is selected numerical value enabling
to sending or returning the laundry 1 once time.
[0086] Subsequently, an action of this invention will be described as follows:
[0087] At first, as shown in FIG. 15, an operator sets the laundry 1 such as a handkerchief
or the like on the upper surface of the lower iron 2 facing to the operator and turns
on the switch 16 of the driving device 6. Then, the motor acting as the driving device
6 rotates in a normal direction and the transmittance wheels 24 rotate in a normal
direction, resulting in that the laundry 1 is once transmitted onto the iron main
body 21 together with the moving cover 22.
[0088] Then, as the laundry 1 is press finished with the upper iron 3 and the upper iron
3 is opened, the motor acting as the driving device 6 is rotated in a reverse direction
under application of a signal got from the control circuit 17. As a result, the transmittance
wheels 24 are rotated in a reverse direction and the laundry 1 is returned back in
a forward direction together with the moving cover 22. Its returning position may
be a set position or it may be a position where the laundry 1 is dropped from the
front end of the lower iron 2 and returned back to be recovered.
[0089] In addition, this invention may also be made such that, as shown in FIGS. 17 to 21,
a set work auxiliary device 18 for expanding the laundry 1 in a lateral direction
and setting it on the moving cover 22 is installed above the lower iron 2 and the
front side position of the upper iron 3. In this case, as the laundry 1, there is
provided
such the laundry as one in which an operator hardly sets it with both hands of the
operator being expanded, for example, a wide laundry such as the sheets and the like.
[0090] The set work auxiliary device 18 is formed to be provided with a pair of right and
left clampers 18a and a sliding mechanism 18b for sliding the clampers 18a in such
a direction as one in which they are moved away from each other.
[0091] The clampers 18a are formed in such a way that when a photoelectric sensor 18a2,
for example, detects an entering of the end part of the laundry 1 between the upper
and lower holding pieces 18a1, the rod in the cylinder 18a3 is extended to hold the
laundry 1.
[0092] Additionally, the sliding mechanism 18b is formed to be provided with a horizontal
guide member 18b1 arranged along a lateral direction for guiding the clampers 18a,
and a pair of cylinder devices 18b2 arranged horizontally along the lateral direction
in the same manner as that of the guide member 18b1. The rod in each of the cylinder
devices 18b2 is arranged in opposition to each other and the clampers 18a are connected
to the extremity end of each of the rods through a fixing member 19 in such a way
that they can be turned around a vertical shaft 20.
[0093] The guide member 18b1 and the cylinder devices 18b2 are arranged at a front side
supporting frame 41, and there limit switches 32 turned on through an inward rotation
of the clampers 18a around the vertical shaft 20 are arranged at the proper positions
of right and left ends of the supporting frame 41.
[0094] Further, the set work auxiliary device 18 may be one which is formed in such a way
that it can be retracted together with the supporting frame 41 under its non-use state
by forming the supporting frame 41 in such a way that it can be turned in a rear side
upward direction.
[0095] Subsequently, an action of this set work auxiliary device 18 will be described as
follows.
[0096] An operator inserts the right and left ends of the laundry 1, the sheets for example,
into a point between the holding pieces 18a1 of each of the clampers 18a under a condition
in which the clampers 18a are approached to each other. Then, the optical path of
the photoelectric sensors 18a2 is shut off, the rod in the cylinder 18a3 is extended
with a signal got from each of the photoelectric sensors 18a2 and the right and left
ends of the laundry 1 are held.
[0097] Then, a signal got from the cylinder 18a3 is received and the rod in each of the
cylinder devices 18b2 is extended. As a result, the clampers 18a are guided by the
guide member 18b1 and moved to the side, respectively, so as to expand the laundry
1 in a lateral direction and keep it in tension. Then, as the rod is further extended,
the clampers 18a are turned inwardly around the vertical shaft 20 through a resistance
force of the tensioned laundry 1 and the limit switches 32 are operated.
[0098] With this operation, the driving operation of each of the cylinder devices 18b2 is
terminated and simultaneously the rod in the cylinder 18a3 is retracted and fixing
of the right and left ends of the laundry 1 is released. As a result, the laundry
1 drops onto the lower iron 2 and is arranged with its right and left portions being
expanded.
[0099] Further, when the laundry 1 is arranged on the lower iron 2, the rods in the cylinder
devices 18b2 are retracted and the clampers 18a are arranged at the front central
part of the lower iron 2 under a state in which they are approached to each other.
[0100] In addition, as shown in FIG. 22 and FIG. 23, this invention may be applied as one
in which a guard member 70 is arranged at the front side of the upper iron 3 so as
to prevent the operator' s hand or fingers from entering below the upper iron 3. The
guard member 70 is formed into a lateral plate, for example, and is arranged over
an entire lateral direction of the upper iron 3. The central part of the guard member
70 is fixed to the upper surface of the upper iron 3 with a fixing member 71.
[0101] The fixing member 71 is formed by a pair of right and left lateral members 72 extending
in a forward or rearward direction and vertical members 73 pivotally arranged at the
front side of the lateral members 72. The rear end of the lateral member 72 is pushed
against the upper surface of the upper iron 3 with a coil spring 74. In addition,
both upper sides of the guard member 70 are pivotally attached to the extremity ends
of the supporting members 75. The rear ends of the supporting members 75 are pivotally
attached to the right and left columns 76. Additionally, the guardmember 70 is resiliently
repelled forward with springs 77 arranged inside the supporting members 75. The front
side of each of the supporting members 75 is covered with a cover 78. Then, in the
case of this invention in this preferred embodiment, a sensor 79 such as a limit switch
or the like that is turned on when the operator's hand or fingers contact with the
guard member 70 is arranged inside the cover 78. This sensor 79 is electrically connected
to the aforementioned controller 5 (the control circuit part 17 in the case of the
device of this invention shown in FIG. 14) and is formed in such a way that when the
sensor 79 is turned on, the driving operation of the driving device 6 is terminated.
[0102] Next, an action of this invention in this preferred embodiment will be described
as follows:
[0103] At first, when the operator's hand or fingers contact with the guard member 70, the
guard member 70 is pushed rearward to cause the sensor 79 to be turned on. Then, the
controller 5 receives signal from the sensor 79 and sends a stop signal to the driving
device 6 and the driving device 6 stops. With this operation, the operator's hand
or fingers are prevented from being held with the upper iron 3.
[0104] Subsequently, when the operator' s hand or fingers are moved away from the guard
member 70, the guard member 70 returns back with a force of the spring 77 and is arranged
in a slant form. With this operation, the sensor 79 is turned off, the driving device
6 is started again and the laundry 1 is sent together with the moving cover 22.
[0105] Further, motion of the guard member 70 is restricted with the fixing member 71, coil
spring 74 and supporting member 75, and the guard member 70 is arranged at a location
slightly above the moving cover 22 so as not to be contacted with the moving cover
22 when the moving cover 22 is moved as indicated by a solid line in FIG. 23.
[0106] In addition, as shown in FIG. 24, this invention may also be applicable to one in
which members 80 for preventing the moving cover 22 from generating any zigzag motion
are arranged at both sides of the lower iron 2. The zigzag motion preventing members
80 in this preferred embodiment are formed with rollers.
[0107] The rollers acting as the members 80 for preventing the zigzag motion in this preferred
embodiment arranged at both front sides of the lower iron 2, inclined in a slant inward
direction and faced upward inside the base frame 811 Side edges of the moving cover
22 are frictionally contacted with the peripheral surfaces of the rollers to restrict
its lateral motion. As a result, with this arrangement, the laundry 1 is sent straight
together with the moving cover 22 and neatly press finished.
