Summary of the Invention
Problems to be Solved by the Invention
[0005] In such washing operation, the aforementioned liquid-current-type woven fabric treatment
apparatus sometimes repeatedly discharges the treating liquid in the apparatus and
supplies unused washing liquid. Specifically, after discharging a certain amount of
the treating liquid in the apparatus, unused washing liquid is supplied to circulate
through the woven fabric for a certain time so that the residual treating liquid in
the woven fabric is mixed with the supplied unused washing liquid to dilute the residual
treating liquid in the woven fabric, and the discharge of a certain amount of the
treating liquid in the apparatus starts again to repeat the procedure on some occasions.
[0006] However, because water absorbency of the woven fabric itself can prevent the discharge
of the treating liquid, and can reduce discharge efficiency of the treating liquid,
a large amount of unused washing liquid is required to repeatedly discharge the treating
liquid and supply unused washing liquid in order to sufficiently dilute the remaining
treating liquid in the apparatus.

Modes for Carrying Out the Invention
[0016] The following description describes a liquid-current-type woven fabric treatment
apparatus according to one embodiment of the present invention with reference to FIGS.
1 and 2. A liquid-current-type woven fabric treatment apparatus 1 (hereinafter referred
to simply as a "woven fabric treatment apparatus 1") is a woven fabric treatment apparatus
for washing woven fabric C with washing liquid after treatment using treating liquid.
The woven fabric treatment apparatus 1 according to this embodiment is a so-called
dyeing machine configured to dye woven fabric with dyeing liquid as treatment using
treating liquid. In addition to dyeing or instead of dyeing, pretreatment such as
scouring and bleaching, and post-processing such as finishing treatment (for example,
flame repelling treatment) may be performed. Although this woven fabric treatment
apparatus 1 washes woven fabric with unused washing liquid of water as washing using
washing liquid, the woven fabric treatment apparatus can wash woven fabric with washing
liquid containing a cleaning agent dissolved in water. A liquid other than water may
be used depending on types of treatment.
[0017] The woven fabric treatment apparatus 1 includes a treatment tank 2 including a first
end 21, a second end 22 that is arranged on a side opposite to the first end 21, and
a body part 23 that is arranged between the first end 21 and the second end 22 and
configured to retain the treating liquid as shown in FIG. 1. The woven fabric treatment
apparatus 1 includes a transfer tube 3 connecting the first end 21 and the second
end 22 to form a circulation path R through which the woven fabric C is circulated
together with the body part 23, and a washing liquid supply system 4 configured to
supply the washing liquid to the treatment tank. In this embodiment, a direction of
circulating movement of the woven fabric C is a counterclockwise direction in FIG.
1. Also, the woven fabric treatment apparatus 1 includes a treating liquid supply
system 8 configured to supply the treating liquid to the treatment tank 2. The treatment
tank 2 includes a press device 7 arranged between a retention part 6 for retaining
the treating liquid and a direction changer 5, and configured to separate the treating
liquid that is included in the woven fabric C from the woven fabric C by pressing
the moving woven fabric C to be circulated.
[0018] The treatment tank 2 is a horizontally elongated tank (tubular tank) that can be
watertightly closed. In the woven fabric treatment apparatus 1 according to this embodiment,
the first end 21, the main body 23 and the second end 22 are connected in series in
the treatment tank 2 so that an internal space of the treatment tank is integrally
formed. Hereinafter, an edge on the first end 21 side (left side edge in FIG. 1) in
the horizontal direction is referred to as one end, and an edge on the second end
22 side (right side edge in FIG. 1) is referred to as another end.
[0019] The main body 23 has a cylindrical body part 231 slightly inclined downward from
another end toward one end, and a tapered part 232 tapered from the body part 231
toward the first end 21. The tapered part 232 is connected to one end of the body
part 231 with being inclined upward from from the body part 231 toward one end. The
body part 23 is not necessarily partially tapered, and a cylindrical body having the
same diameter as the body part 231 may be connected to one end of the body part 231.
[0020] Also, the main body 23 has a drain 233 that opens downward. In the woven fabric treatment
apparatus 1 according to this embodiment, the main body 23 (specifically, the tapered
part 232) includes a lower protrusion 234 protruding downward, and the drain 233 is
formed in the lower protrusion 234. In addition, in the woven fabric treatment apparatus
1 according to the embodiment, the main body 23 (specifically, the tapered part 232)
includes an upper protrusion 235.
[0021] The first end 21 is a part to which an end on the one end side of the transfer tube
3 is connected, and a part for receiving the woven fabric C fed from the treatment
tank 2 to the transfer tube 3. Specifically, the first end 21 includes a cylindrical
first end body 211 continuously extending from the tapered part 232, and a connection
part 212 extending downward from a lower part of the first end body 211 and connected
to the transfer tube 3.
[0022] The direction changer 5 is arranged in the first end part 21, and is configured to
change a movement direction of the woven fabric C so as to pass the woven fabric C
through the transfer tube 3. The direction changer 5 is a member for transporting
and guiding the woven fabric C.
[0023] In the woven fabric treatment apparatus 1 according to this embodiment, a reel 214
is arranged as the direction changer 5 in the first end 21. Specifically, the reel
214 is arranged in the first end body 211. The reel 214 includes a plurality of multiple
bar-like members that are configured to contact the moving woven fabric C to be circulated,
and are spaced at a fixed interval in a circumferential direction, and rotates about
an axis orthogonal to the travel direction of the woven fabric C in the treatment
tank 2 (leftward/rightward direction in FIG. 1) and an upward/downward direction.
The reel 214 is rotatably driven by an electric motor 215, for example, as shown in
FIG. 2.
[0024] The first end body 211 includes an opening/closing door 213 on one end. The opening/closing
door 213 can be changed between an arrangement in which one end of the treatment tank
2 is opened (opened arrangement) and an arrangement in which one end is watertightly
closed (closed arrangement).
[0025] The second end 22 is a part to which an end of the another end side of the transfer
tube 3 is connected, and a part for receiving the woven fabric C fed from the transfer
tube 3 to the treatment tank 2. This second end 22 closes another end of the treatment
tank 2.
[0026] The transfer tube 3 connects (couples) the first end 21 and the second end 22 to
form the circulation path R through which the woven fabric C can be circulated together
with the treatment tank 2. Specifically, the transfer tube 3 is a roughly U-shaped
pipe including a main tube part 30 that extends under the treatment tank 2 in a horizontal
direction, a first vertical part 31 that extends from one end of the main tube part
30 to the connection part 212, and a second vertical part 32 that extends upward from
another end of the main tube part 30 to the second end 22.
[0027] The washing liquid supply system 4 includes a new liquid supplier 40 that is arranged
on a downstream side in a direction of the circulating movement of the woven fabric
C relative to the press device 7 in the circulation path R on the circulation path,
and is configured to supply unused washing liquid. The new liquid supplier 40 is,
for example, a nozzle arranged in the connection part 212. The nozzle is configured
to spray the washing liquid diagonally downward toward a center in the connection
part 212 at a high speed. In the woven fabric treatment apparatus 1 according to this
embodiment, the nozzle sprays the washing liquid from the entire circumference surrounding
the center of the connection part 212 toward a center of a lower end of the connection
part 212 at high speed.
[0028] The press device 7 includes a pair of rollers 70 configured to pinch the woven fabric
C from both sides of the woven fabric C in a direction intersecting the direction
of the circulating movement as shown in FIG. 2, for example. In other words, the press
device 7 is a so-called mangle type roller device. In the woven fabric treatment apparatus
1 according to this embodiment, the press device 7 presses the woven fabric C during
the woven fabric is washed with the washing liquid after treatment using the treating
liquid. The press device 7, for example, is arranged in a substantially center position
between the retention part 6 of the processing fluid and the direction changer 5.
[0029] In the woven fabric treatment apparatus 1 of this embodiment, the pair of rollers
70 are arranged side by side in a direction orthogonal to the direction of the circulating
movement of the woven fabric C. Each of the pair of rollers 70 is configured to rotate
about a rotation axis extending a direction intersecting the direction of the circulating
movement of the woven fabric C, more specifically extending a direction intersecting
both a direction intersecting the direction of the circulating movement and the direction
of the circulating movement. The pair of rollers 70 include flange parts 700 on ends
of a roller (ends in a direction intersecting the direction of the circulating movement).
One roller 71 of the pair of rollers 70 is arranged on a lower side of the woven fabric
C and another roller 72 is arranged on an upper side of the woven fabric C. The flange
parts 700 in this embodiment are circular flange shaped parts arranged on both the
ends of one roller 71.
[0030] At least one roller 71 of the pair of rollers 70 is configured to move toward and
away from another roller 72. In the woven fabric treatment apparatus 1 according to
this embodiment, the pair of rollers 70 are arranged at separated positions away from
each other during treatment using the treating liquid, and at adjacent positions to
each other during washing using the washing liquid. Specifically, one roller 71 (for
example, one roller 71 arranged on the lower side) is configured to move toward and
away from another roller 72. Both rollers 71 and 72 can be configured to move toward
and away from each other.
[0031] The movable roller 71 of the pair of rollers 70 is a follower roller. The movable
roller 71 is pivotably supported by the body part 23. More specifically, the movable
roller 71 is supported by a movable arm 73 as shown in FIG. 2. The roller 71 moves
between lower and upper positions along an arc centering a pivot axis extending in
a direction intersecting the direction of the circulating movement of the woven fabric
C, for example. At least a part of the roller 71 (for example, a lower half of the
roller 71) can be arranged in the lower protrusion 234.
[0032] For example, an air cylinder 74 is used to move the roller 71 (see FIG. 1). A longitudinal
direction of the air cylinder 74 is parallel to an extension direction of the main
body 23 (tapered part 232 in this embodiment). The air cylinder 74 is arranged beside
the main body 23 at a deviated position in a depth direction of the main body 23.
The air cylinder 74 is connected to the movable roller 71 by a link 75 having one
end connected to the air cylinder 74 and another end connected to the arm 73, for
example.
[0033] One end of the link 75 is connected to a free end of the air cylinder 74 by a rotational
shaft. Another end of the link 75 is connected to the arm 73 by a rotational shaft.
Parts including the one end of the link 75 is located outside the body part 23 and
beside the body part 23. The rotational shaft connecting the arm 73 to the link 75
extends in the horizontal direction, and penetrates the main body 23. The rotational
shaft extends parallel to the rotation axis of the another roller 72. The rotational
shaft is constructed of a single rod, for example. Specifically, the rod extends in
the horizontal direction from a position aligned with one end of the movable roller
71 to a position aligned with another end of the movable roller 71.
[0034] Specifically, telescopic movement of the air cylinder 74 is transmitted to the roller
71 through the arm 73 and the link 75 to move the roller 71 so that a push force of
the air cylinder is transmitted to the roller 71 to push the roller 71 toward the
woven fabric C. The air cylinder 74 is driven through a control console (not shown)
of the woven fabric treatment apparatus 1, and can be driven by an operation on a
switch or automatic control. An air pressure supplied to the air cylinder 74 is adjusted
by a mechanism that includes a pressure reducing valve.
[0035] In the woven fabric treatment apparatus 1 according to this embodiment, the drain
233 of the main body 23 is arranged under a movement area of the arm 73. As a result,
waste liquid squeezed by the pair of rollers 70 (residual treating liquid separated
from the woven fabric C) can be immediately drained to the outside of the main body
23.
[0036] The movable roller 72 of the pair of rollers 70 is a roller that is fixed to the
main body 23 and can be driven or be rotated following the movement of the woven fabric.
The roller 72 can be driven by electric motor power, specifically the roller 72 is
driven through a belt or chain that transmits the rotational force from the electric
motor, example. For example, the electric motor is driven through the control console
of the woven fabric treatment apparatus 1, and a rotation speed and torque of the
electric motor can be changed an operation on a switch or automatic control. In the
woven fabric treatment apparatus 1 according to this embodiment, the pair of rollers
70 are rotated at a speed synchronized with a speed of the circulating movement of
the woven fabric C thereby reducing damage on the woven fabric C caused by washing.
At least a part of the roller 72 (for example, an upper half of the roller 72) can
be arranged in the upper protrusion 235.
[0037] In the above-mentioned woven fabric treatment apparatus 1, the woven fabric C circulating
in a circular rope-like shape is pressed (squeezed) by the stationary roller 72, which
can be driven or be rotated following the movement of the woven fabric, and the movable
roller 71, which is a follower roller, so that residual treating liquid adhered to
surfaces of woven fabric C and residual treating liquid absorbed in the woven fabric
C are separated from the woven fabric C and are then drained to the outside of the
apparatus through the drain 233, which is opened downward in the main body 23. After
that, the woven fabric C from which the treating liquid is separated by squeezing
is supplied with only the unused washing liquid, and washed with water. In the woven
fabric treatment apparatus 1 according to this embodiment, because the drain 233 is
arranged in the lower protrusion 234 of the main body 23 (specifically, the tapered
part 232), the waste liquid separated from the woven fabric C can be temporarily retained
in the lower protrusion 234 and be prevented from mixing with other liquid in the
treatment tank 2.
[0038] Here, in liquid-current-type woven fabric treatment apparatuses, difficulties for
achieving improvement of washing efficiency arise in the following mechanisms. Specifically,
because a shape of the woven fabric to be washed (after treatment using the treating
liquid) is not stationary when placed in the liquid-current-type woven fabric treatment
apparatus, it is difficult to achieve "improvement of washing efficiency by using
a mechanism that applies air pressure to dyed woven fabric after dyeing", which can
be achieved by yarn dyeing machines. Also, because the liquid-current-type woven fabric
treatment apparatus has a structure that holds the woven in the circulation path including
the treatment tank and the transfer tube dissimilar to product dyeing machines, which
has a structure that holds a dyed product in a cylindrical inner tank, it is difficult
to achieve "improvement of washing efficiency bu using a mechanism that uniformly
applies a centrifugal force to the dyed product", which can be achieved by the product
dyeing machines.
[0039] Contrary to this, according to the woven fabric treatment apparatus 1 of this embodiment,
because the treating liquid is separated from the woven fabric C by pressing the woven
fabric C by using the press device 7 after the woven fabric is treated (for example,
dyed), it is possible to reduce an amount of washing liquid used for washing, i.e.,
an amount of washing liquid used to removing the treating liquid included in the woven
fabric C (for example, unused washing liquid used for washing the woven fabric with
water). Consequently, it is possible to improve washing efficiency.
[0040] In the woven fabric treatment apparatus 1 according to this embodiment, because the
moving woven fabric C to be circulated is pressed by the press device 7 so that an
amount of treating liquid that is included in the woven fabric is reduced, and then
is washed with unused washing liquid, it is possible to efficiently wash the woven
fabric C.
[0041] Also, in the woven fabric treatment apparatus 1 according to this embodiment, because
the pair of rollers 70 nip the woven fabric C while rotating, damage on the woven
fabric C can be reduced as compared to a structure that includes fixed member rubbing
against the woven fabric C. Specifically, even if thickness of the woven fabric C
is uneven (for example, a sewed part is formed in the woven fabric C (the woven fabric
C is partially doubled and sewed)), because the roller 71, which can correspondingly
move together with the arm (for example, the arm moved by the air cylinder) 73, is
not fixed but gently presses the woven fabric C, it is possible to prevent that a
strong force is applied to the part of the woven fabric C that is thicker.
[0042] Also, in this embodiment of woven fabric treatment apparatus 1, because the pair
of rollers 70 can be arranged at separated positions away from each other during treatment
using the treating liquid so that the pair of rollers 70 move to distant positions
away from the circulation path R to prevent interference with the woven fabric C,
the woven fabric C can be smoothly circulated.
[0043] In the woven fabric treatment apparatus 1 according to this embodiment, because the
movable roller 71 is supported by the arm 73, it is possible to simplify a structure
relating to the roller 71 as compared to a structure that moves the pair of rollers
70 parallel to each other, for example. Also, because a through hole through which
the shaft for pivotably supporting the arm 73 passes is formed in the main body 23
so that a mechanism for moving the arm 73 (air cylinder, etc.) can be arranged outside
the main body 23, it is possible to simplify a mechanism of the press device 7 for
pressing the woven fabric C inside the main body 23.
[0044] Also, In the woven fabric treatment apparatus 1 according to this embodiment, when
the woven fabric C is sandwiched between the pair of rollers 70, the flange part 700
of one roller 71 can prevent the woven fabric to from disengaging from the pair of
rollers 70 in a width direction (longitudinal direction of the pair of rollers 70).
[0045] The woven fabric treatment apparatus according to the present invention is not limited
to the aforementioned embodiment, and needless to say various modification can be
made without departing from the spirit of the present invention. For example, a component
in one embodiment can be added to another embodiment, and some of components in one
embodiment can be replaced with compositions in another embodiment. Also, some of
components in one embodiment can be removed.
[0046] Although it has been illustratively described that the press device 7 presses the
woven fabric C during the woven fabric is washed with the washing liquid after treatment
using the treating liquid in the woven fabric treatment apparatus 1 according to the
aforementioned embodiment, the press device 7 presses the woven fabric C before the
start of the washing using the washing liquid after treatment using the treating liquid.
Even in this configuration, an amount of washing liquid used for washing can be reduced
by pressing the woven fabric C by using the press device 7 to separate the treating
liquid from the woven fabric before washing.
[0047] Although it has been illustratively described that the press device 7 includes the
pair of rollers 70 in the aforementioned embodiment, the press device can include
a fixed bar and a roller configured to sandwich the woven fabric C from both sides
of the woven fabric, or a pair of bars configured to sandwich the woven fabric C from
both sides of the woven fabric.
[0048] Although it has been illustratively described that the movable roller 71 of the pair
of rollers 70 is moved along an arc by the arm 73 in the aforementioned embodiment,
the movable roller can be moved by a different member from the arm 73, for example,
can be slid (be slide, e.g., in a direction orthogonal to the direction of the circulating
movement).
[0049] Although it has been illustratively described that one roller 71 is the movable roller
and another roller 72 is the stationary roller in the pair of rollers 70, both the
rollers 71 and 72 can be movable rollers relative to the main body 23 or both the
rollers 71 and 72 can be stationary rollers.
[0050] Although it has been illustratively described that the pair of rollers 70 are aligned
in a direction orthogonal to the direction of the circulating movement of the woven
fabric C, the rollers 71 and 72 can be arranged at deviated positions from each other
in the direction of the circulating movement so that the woven fabric C is meandered
in an S shape by the pair of rollers 70 in this case.
[0051] The movable roller 71 can be moved by a driver other than the air cylinder 74. The
configuration that supports the roller 71 is not limited to the aforementioned configuration.
For example, the pivot shaft connecting the arm 73 to the link 75 can be constructed
of a plurality of rods. Specifically, the pivot shaft can be constructed of two rods,
and the two rods do not necessarily extend from a position aligned with one end of
the movable roller 71 to a position aligned with another end of the movable roller
71 in this case.
[0052] The press device 7 may be constructed of one roller 71. For example, as shown in
FIG. 3, the press device 7 may be a roller 71 configured to press the woven fabric
C by moving in one direction intersecting the direction of the circulating movement
of the woven fabric C. In this case, it is possible to further simplify a configuration
of the press device 7.
[0053] The treatment tank 2 can have a different shape from the aforementioned shape. For
example, at least one of the lower protrusion 234 and the upper protrusion 235 can
be omitted in the treatment tank 2. The treatment tank 2 does not necessarily include
the drain 233.
[0054] A liquid-current-type woven fabric treatment apparatus according to the present invention
is a liquid-current-type woven fabric treatment apparatus for washing woven fabric
with washing liquid after treatment using treating liquid, the liquid-current-type
woven fabric treatment apparatus including a tubular treatment tank including a first
end, a second end that is arranged on a side opposite to the first end, and a body
part that is arranged between the first end and the second end and configured to retain
the treating liquid; a transfer tube connecting the first end and the second end to
form a circulation path through which the woven fabric is circulated together with
the body part; a treating liquid supply system configured to supply the treating liquid
to the treatment tank; and a washing liquid supply system configured to supply the
washing liquid to the treatment tank, wherein a direction changer is arranged in the
first end part, and is configured to change a movement direction of the woven fabric
so as to pass the woven fabric through the transfer tube, and the treatment tank includes
a press device arranged between a retention part for retaining the treating liquid
and the direction changer, and configured to separate the treating liquid that is
included in the woven fabric from the woven fabric by pressing the woven fabric moving
to be circulated.
[0055] According to this structure, an amount of washing liquid can be reduced by pressing
the woven fabric by using the press device to separate the treating liquid from the
woven fabric after the woven fabric is treated.
[0056] In addition, in the aforementioned liquid-current-type woven fabric treatment apparatus,
the washing liquid supply system can include an unused washing liquid supplier that
is arranged on a downstream side in a direction of the circulating movement relative
to the press device on the circulation path, and is configured to supply unused washing
liquid.
[0057] According to this structure, because the woven fabric moving to be circulated is
pressed by the press device, and then is washed with unused washing liquid, it is
possible to efficiently wash the woven fabric.
[0058] In addition, in the aforementioned liquid-current-type woven fabric treatment apparatus,
the press device can include a pair of rollers configured to pinch the woven fabric
from both sides of the woven fabric in a direction orthogonal to the direction of
the circulating movement.
[0059] According to this configuration, because the pair of rollers nip the woven fabric
while rotating, damage on woven fabric can be reduced.
[0060] In addition, in the aforementioned liquid-current-type woven fabric treatment apparatus,
at least one of the pair of rollers can be configured to move toward and away from
another roller.
[0061] According to this configuration, because the pair of rollers can be arranged at separated
positions away from each other during treatment using the treating liquid to prevent
interference with the woven fabric, the woven fabric can be smoothly circulated.
[0062] In addition, in the aforementioned liquid-current-type woven fabric treatment apparatus,
the at least one of the pair of rollers, which is movable, can be supported by an
arm that is pivotably supported by the body part.
[0063] According to this configuration, it is possible to simplify a structure relating
to the movable roller.
[0064] In addition, in the aforementioned liquid-current-type woven fabric treatment apparatus,
the pair of rollers can have flange parts that are arranged on ends of a roller.
[0065] According to this configuration, the woven fabric is unlikely to disengage from the
pair of rollers when the woven fabric is sandwiched between the pair of rollers.
[0066] In addition, in the aforementioned liquid-current-type woven fabric treatment apparatus,
the press device can be a roller that is configured to press the woven fabric by moving
in one direction intersecting the direction of the circulating movement.
[0067] According to this configuration, it is possible to further simplify a configuration
of the press device 7. Description of Reference Numerals
