[0001] This invention refers to a press for wringing the water out of wet clothing.
[0002] This machine is applicable at an industrial level for use in hotels, clinics, barracks,
schools and in general any establishment where large quantities of clothing, table
cloths, bed sheets, serviettes, shirts and other similar materials must be washed
and ironed.
[0003] As is known, these types of establishments have washing machines, wringers for the
wet clothing, dryers and ironing machines installed.
[0004] In particular, the machines and equipment for wringing wet clothing usually consist
of a enclosure set on a perforated floor in which the wet clothing is deposited to
receive the action of a press. In these cases, given that the upper surface of the
pile of clothing is not uniform, pressing action is not uniform either, and some parts
of the clothing or fabrics are wrung more than other parts unless very strong pressing
takes place, which could damage the fabrics.
[0005] To resolve these problems, machines have been envisaged made up of the enclosure
in which the wet clothing is placed, and in which prepressing or light compacting
pressing occurs, and a bell type press with a membrane acts uniformly through this
upon the pile of clothing, and which under the bell-press the round enclosure is moved
with the clothing, and whose enclosure is withdrawn before the bell-press is lowered
to begin pressing action.
[0006] These machines have the disadvantage that during the lapse of time in which the enclosure
is withdrawn till the lowering of the bell-press, the pile of clothing falls to pieces,
especially when the fabrics are made of polyester, which are being used more and more
every day, due to the spring effect, and in these circumstances, when the bell-press
is lowered, some of the clothing remains outside the periphery of the bell, resulting
in defective pressing action, and subsequently, in badly wrung clothing unless this
scattering of the clothing is corrected beforehand, which would entail the use of
extra manpower and delay the wringing process, with the notable financial loss that
this entails for each operation, thereby making the operation less profitable.
To correct this disadvantage in this type of machine, it has been envisaged that in
this invention the clothing is accompanied from the enclosure to the interior of the
bell-press, from which it will not be removed until the press has completed its pressing
cycle.
[0007] In order to accomplish this, there is, beneath the working zone of the bell-press,
a multi-perforated platform at the floor level of the machine, and around this platform
the enclosure with the clothing is placed, the platform which can be raised to lift
the clothing and place it inside the bell-press, and the bell-press, clothing and
platform, after the enclusure has been removed, are lowered together to the machine
floor where the pressing and wringing of the clothing is to take place.
[0008] The platform is advantageously raised by means of a telescopic cylinder.
[0009] These and other features will be understood more clearly by the detailed description
which follows, accompanied by three sheets of drawings which show a practical example
of the construction of a machine according to this invention, and which is only an
example and by no means limits the scope of the invention described here.
[0011] Figure 1 shows a frontal elevation of the most important part of the machine.
[0012] Figure 2 shows a top view of the machine floor and the enclosure which receives the
clothing.
[0013] Figure 3 shows a lateral section elevation of the bell-press, elevable platform and
enclosure set.
[0014] Figure 4 shows a top view of the bell-press, and
[0015] Figure 5 shows a schematic diagram of the machine in its different A to F operations.
[0016] In accordance with the Drawings, the wringing machine is made up of a rectangular
multi-perforated floor 1, which on its left half has an enclosure 2 joined to a carriage
3, which by means of wheels 4 is moved along guides 5 through the action of two cylinders
6.
[0017] On the right half of this floor 1, at floor level, there is a multi-perforated circular
platform 7 placed beneath the bell-press 8, provided with a membrane 9, and supported
by the frame 10.
[0018] The platform 7 is mounted on a central telescopic cylinder 11, and the enclosure
2 has a gate 12 facing said cylinder, which closes the lateral opening of the enclosure
to a width analogous to the diameter of said telescopic cylinder, the gate of which
is driven by means of a pneumatic cylinder 13.
[0019] The operation of this machine is as follows, as per Figure 5:
A - The clothing R is deposited in the enclosure 2 and prewringing or light wringing
P takes place.
B - The enclosure 2 is displaced with the clothing around the platform 7 and beneath
the bell-press 8.
C - The telescopic cylinder 11 is activated which raises the platform 7 with the clothing
and introduces it into the bell.
D - The enclosure 2 is withdrawn, thereby opening the gate 12.
E - By means of the cylinder 14, the bell-press 8 is lowered, and at the same time
the platform 7 also lowers with the clothing, through the folding of the telescopic
cylinder 11.
F - The membrane 9 of the bell-press is activated and applies pressure to the clothing
to wring out the water, and at the same time deposits another load of clothing R in
the enclosure (the gate of which is now closed) and proceeds to pre-press the same.
[0020] During the wringing action of the membrane 9, through the intake E of fluid (such
as water) under pressure within the bell-press 8, through its 8' passage, the bell-press
is interlocked with sliding plates 15 to locking dogs 16 fitted to the frame 10 and
driven by the 15' pneumatic cylinder.
[0021] In addition, the bell-press is maintained in the inactive raised position by means
of a safety device 17.
[0022] During its vertical displacement the bell-press slides on wheels 18 along the guides
19 fitted to the frame 10.
1 - Press for wringing the water out of wet clothing, of the type consisting of a mobile
enclosure which receives the wet clothing and moves it to the bell type press with
membrane, characterized by the fact that there is beneath the press at the floor level
of the machine, an elevable multi-perforated platform around which the enclosure with
the clothing is placed, and which is raised by said platform to the interior of the
bell of the press, and when the enclosure is withdrawn, lowers the press, clothing
and platform set to floor level where the pressing function of the membrane acting
on the clothing is carried out.
2 - Press for wringing the water out of wet clothing, as per Claim 1, in which the platform
is raised by means of a telescopic cylinder.
3 - Press for wringing the water out of wet clothing, as per Claim 1, in which the enclosure
has on the side an opening of a width analogous to the diameter of the telescopic
cylinder, and which can be closed by means of a gate which completes the enclosure.
