Description

TECHNICAL FIELD The present invention relates to improvements in diaphragm-type presses for expressing liquid from liquid-containing materials, such as items to be washed. More specifically, the present invention relates to a press device as described above that allows the diaphragm to be replaced easily and in a short time and has excellent pressing effects.

Problems with the Prior Art In conventional diaphragm type press equipment, the tire phragm made of similar elastic materials is tightly attached to a pressurizing body having a pressurizing chamber by bolts, screws, or other clamping devices. It was fixed (・ta.

It is written in the Gaga No. etc.

In such conventional devices, when the diaphragm becomes worn or damaged due to use, the clamp devices that secure the diaphragm are removed and the diaphragm is replaced. The work of replacing such a diaphragm (1) generally did not have enough work space and the number of clamping devices was 6 to 7 or more. This was a relatively time-consuming and tedious task.

In addition, in the conventional diaphragm type press device, when the pressure medium is introduced into the pressurized chamber in the non-pressing state, the diaphragm assumes its natural extended state, and The diaphragm was in a generally stretched state during the press state, ie when a pressure medium was introduced into the pressurized chamber to squeeze out the liquid from the mass of material containing the -C liquid. In order to efficiently express liquid, the diaphragm must further locally deform to follow the contour of the mass of material to be expressed, but in conventional presses, the diaphragm deforms to some extent. It has the disadvantage that it comes into contact with the lump of material to be squeezed out in its fully stretched state, and is unable to stretch further to follow the contour of the lump.

This impairs the uniformity of the squeezing operation and also has an adverse effect on the lifespan of the diaphragm itself.

(3) Summary of the Invention It is an object of the present invention to provide a new and efficient diaphragm type press device which eliminates the drawbacks of the prior art devices mentioned above. That is, an object of the present invention is to provide a diaphragm type press device in which the diaphragm can be replaced easily and at the appropriate time.

Another object of the invention is to bring the diaphragm into contact with the mass of material to be expressed in an unextended state, thereby
To provide a diaphragm type press device in which a diaphragm can easily follow the contour of a mass.

Still another object of the present invention is to maintain the diaphragm in the H-8 body by means of negative pressure within the pressure chamber;
On the other hand, it is an object of the present invention to provide a diaphragm type press device 6 in which a diaphragm can be removed from a pressurizing body simply by setting the pressure in a pressure chamber to atmospheric pressure. A diaphragm-type press device for squeezing a liquid from a mass of liquid-containing material, comprising a support member for supporting the mass, and a pressure chamber closed by a tie flar AIC. The diaphragm has a pressurizing body that can reciprocate with respect to the mass placed thereon; the diaphragm is tightly fitted into the cylindrical part of the pressure chamber with the ring installed in a part of the notch. It is inserted;
Thereby, when a pressurized medium is introduced into the pressure chamber at high pressure, the diaphragm suppresses the liquid-containing lump (-゛C) and squeezes out the liquid, while in the non-pressing state- The diaphragm provides a press device which is held on the pressurizing body by the negative pressure in the pressure chamber.As described below, in the diaphragm press device of the present invention is a diaphragm and a car bolt.

Since the diaphragm is not clamped by a screw or other clamping device but by negative pressure from the pressure chamber C, it is sufficient to simply bring the pressure inside the pressure chamber to atmospheric pressure in order to remove it from the pressurizing body in order to replace the diaphragm. Moreover, in the normal press operation 14, the mass of material containing liquid is transferred to the support part 2.
When raising the pressure body to place it on the pressure chamber, the inside of the pressure chamber is made negative and positive to prevent the diaphragm from falling off the pressure body, and the diaphragm is expanded so that it sticks to the inner wall of the pressure chamber. This creates a space on the underside of the diaphragm that accommodates the mass of liquid to be squeezed out.
On the other hand, when introducing a pressurizing medium into the pressure chamber in order to squeeze out a mass of material placed on the support member, the pressurizer is lowered onto the support member, There is no need to take precautions to prevent the diaphragm from falling off the pressurizing body.

When a pressurized medium is introduced into the pressure chamber, the diaphragm returns from its stretched position along the inner wall of the pressure chamber to its original unstretched state, so that the diaphragm returns to its original position (Jt). The outline of the mass of material to be squeezed out is so that it can be easily followed.

(4) Description of preferred embodiments Next, the structure of the present invention will be specifically described with respect to the embodiments shown in the drawings.

The configuration of a press device for squeezing liquid from a liquid-containing material according to the present invention will be described as an example of a press device used for dehydrating items to be washed.

In the drawings, reference numeral 1 denotes a diaphragm type press device according to the present invention, which schematically includes a pair of columns 2, a piston-cylinder device 3 disposed on the top of the column 2, and a vertical direction by the piston-cylinder device 3. It is composed of a pressurizing body 4 supported so as to be able to reciprocate, and a support portion 5 disposed below the pressurizing body 4.

Reference numeral 6 designates an endless conveyor belt for transporting a mass of liquid-containing material, for example a mass of laundry 7, above the support member 5 and below the pressure body. The support member 5 and the endless conveyor belt 6 are provided with means, such as holes, grooves, etc. (not shown), for allowing the squeezed liquid to flow downward. The pressurizing body 4) has a bushing 8 that is loosely fitted to the pillar 2, and a pressure chamber 9 that opens downward and is heated to a temperature of .degree. Open bottom of pressure chamber [ni
A cylindrical portion 10 is provided at an inner wall location close to.

An elastic diaphragm 11 covers the open bottom surface of the pressure chamber 9 of the pressurizing body 4, and the pressure chamber 9
extends continuously within the ram 12 of the piston-cylinder arrangement 3 and communicates with the pressure source J3 via a filter conduit.

The peripheral edge of the diaphragm J and the inner wall of the pressurizing body 4 must be sealed at least when the pressure chamber 9 is under negative pressure.

Specific examples thereof are illustrated in FIGS. 2 and 3. In FIG. 2, J4 is an edge formed on the periphery of the diaphragm 11, and a circular notch 15 is formed on the inside thereof all around the periphery. A reinforcing ring 16 having a substantially circular cross section is positioned within this notch 15 .

It is preferable to provide a flat abutting surface 17 as shown above the reinforcing ring 16. At predetermined positions on the inner wall of the pressurizing body 4, the reinforcing ring 1G, C1d, and diaphragm 211 are installed to apply pressure. A stopper 18 is fixed to support them so that they do not enter the chamber 9. That is, the lower end surface of the stopper 18 comes into contact with the contact surface of the reinforcing ring 16, and supports it so that it does not move. The outer circumferential surface of the edge 14 of the diaphragm 11 may be damaged even when the inside of the pressure chamber 9 is under negative pressure, or when the center of the diaphragm 11 is pressed inward and upward by a mass of washing material 7. At this time, it defines a sealing surface that comes into close contact with the cylindrical portion 10 of the pressurizing body 4. Third
The figure shows another embodiment of a structure that prevents the diaphragm 11 from entering the pressure chamber 9. The reinforcing ring 19 in FIG. It includes a ring part 20 that is fitted into the ring part 20 and has a substantially circular cross section, and a cylindrical part 21 that extends upward from the ring part 20. It is preferable to provide a flat abutment surface on the top surface of the cylindrical portion 2, similar to the reinforcing ring 6 in FIG. At a predetermined position on the inner wall of the pressurized body, there is an abutment provided on the top surface of the reinforcing ring 19 so that the reinforcing ring 19 and, by extension, the diaphragm 11 do not enter into the pressure chamber 9. The reinforcing ring 19 is supported against the surface to prevent it from entering the pressure chamber 9.

Next, the operation of the press apparatus J according to the present invention as described above will be explained in part 1. First, the pressure source 13 is used to create a negative pressure in the pressure chamber 9. The diaphragm 11, as shown in FIG.
The central portion is pushed inward and upward, and the outer surface of the edge 14 is pressed against the cylindrical portion 10 of the pressurizing body 4.
be forced to. Therefore, a good seal is formed between the pressurizing body 4 and the diaphragm, and the diaphragm 1 does not fall off from the pressurizing body even if no special ramp member is provided. , the piston/cylinder device is operated to raise the pressurizing body 4.

At the loading position of the endless conveyor belt 6, 42 stones containing liquid, for example, a mass 7 of washed material, is loaded, and the belt 6 is operated to move the mass 7 of the material to be washed to a position below the pressurizing body 4. 1='. It is preferable that the mass 7 of the object to be washed is press-molded into a shape and height such that when it is placed on the belt 6, it fits perfectly inside the pressurizing body 4.

When the mass of laundry 7 reaches the position h below the pressurizing body 4, the belt 6 stops running and the piston/cylinder device 3 is activated, or the pressurizing body 4 is lowered by its own weight. zero. When the pressure body 4 is supported above the belt 6, the hook 23 is attached to a flange 24 formed around the pressure body 4, as indicated by the dashed line in FIGS. 2 and 3. The hook mechanically prevents the pressurizing body 4 from being lifted up. Next, the pressure source j3 is activated to supply the pressurized medium, e.g.
Air or water, which does not contaminate the items to be washed even if it leaks out, is introduced into the pressure chamber 9 through a conduit formed in the ram 2 of the piston-cylinder device 3.

Due to the pressurizing medium, the diaphragm 11 tries to return to its original unstretched state from the position where it is stuck to the inner wall of the pressure chamber of the pressurizing body 4.

Then, the mass to be washed comes into contact with the rings 7 and 11 in a state that is not fully extended. Therefore, the diaphragm 11 is brought into close contact with the surface of the mass 7 of the object to be washed in all areas, and in this state, sufficient pressure is applied in the pressure chamber 9 so that the mass 7 of the object to be washed is subjected to uniform pressure. After the liquid has been sufficiently squeezed out from the mass, the inside of the pressure chamber 9 is made negative pressure again, and the diaphragm 1 is held so as to stick to the inner wall of the pressure chamber of the pressurizing body 4. Next, the piston-cylinder device 3 is operated to raise the pressurizing body, and the cycle is completed. When the belt 6 is actuated to move the next mass of laundry to be washed below the pressurizing body 4, the mass squeezed out in the previous cycle is transferred from below the pressurizing body 4 to the next stage, such as drying. Transported towards the destination.
