This machine is of the type which has an enclosure (2) in which the clothing (R) to be wrung is deposited, and in which pre-wringing is carried out, and a press (8) in the shape of a bell with a pressing membrane (9). The purpose of the invention is to introduce the wet clothing into the interior of the bell before the pressing action of the membrane takes place, and for which an elevable platform (7) has been envisaged on the floor (1) of the machine around which the enclosure (2) with the clothing (R) is placed, and once the clothing (R) has been raised to the interior of the press bell, after the enclosure (2) has been withdrawn, the bell-press (8), clothing (R) and platform (7) set is lowered to floor level (1), where wringing is carried out through the action of the membrane (9). The platform (7) will be advantageously raised by means of a telescopic cylinder (11), and the enclosure (2) will have on its side a gate (12) with a width analogous to the diameter of said cylinder.
This invention refers to a press for wringing the water out of wet clothing.
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.
As is known, these types of establishments have washing machines, wringers for the wet clothing, dryers and ironing machines installed.
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.
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pile of clothing, and which under the bell-press the round enclosure is moved with the clothing, and whose enclosure is withdrawn before the bell-press is lowered to begin pressing action.
These machines have the disadvantage that during the lapse of time in which the enclosure is withdrawn till the lowering of the bell-press, the pile of clothing falls to pieces, especially when the fabrics are made of polyester, which are being used more and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.
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.
The platform is advantageously raised by means of a telescopic cylinder.
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.
In the Drawings:
Figure 1 shows a frontal elevation of the most important part of the machine.
Figure 2 shows a top view of the machine floor and the enclosure which receives the clothing.
Figure 3 shows a lateral section elevation of the bell-press, elevable platform and enclosure set.
Figure 4 shows a top view of the bell-press, and
Figure 5 shows a schematic diagram of the machine in its different A to F operations.
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.
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.
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.
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.
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.
In addition, the bell-press is maintained in the inactive raised position by means of a safety device 17.
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.
