JPS602240Y2 - Separator for dehydration of rectangular wet paper stacked flat - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a separator used for dewatering wet paper such as TEX.

Generally, hard cardboard is used as the material for shoe insoles.

This type of paper is called Tex or hardboard, and it is very thick and must be processed into a flat board, so it cannot be dehydrated and dried like normal papermaking, and it has to be processed using a wet machine. A thick and shaped wet paper is cut one by one using a wet paper forming machine called a . A vertical press machine 2 called a hydraulic press as shown in FIG.
The method is to press the paper from above and below to force out the water content, and after dehydrating it, peel it off one by one again and expose it to the sun (natural light) to dry.

In Fig. 2, 3 is a movable pressure plate directly connected to a pressure ram 4 that supports the bottom surface of the rectangular wet paper sheets 1 stacked flat, and 5 is a fixed pressure plate that receives the top surface of the same square wet paper sheets 1. The flat-topped wet paper is compressed from above and below between 3 and 4, allowing moisture to escape to the sides, thereby dehydrating the paper.

In the above case, if square wet papers are directly stacked flat and pressed or peeled off, the fibers will adhere to each other on the overlapping surfaces of the wet papers, destroying the paper layer structure and reducing the dewatering efficiency. Therefore, it is desired that a separator of some kind be provided between the wet paper sheets to protect the surface of the wet paper paper, and that the separator facilitates dewatering during the above-mentioned pressing.

In addition, since the wet paper paper 1 has a considerable thickness (5 mm to 1-) and is cut into square wet paper paper, the edges of the wet paper paper swell more easily than the other parts, forming a double layer 1a. When stacked, the third
As shown in the figure, the periphery protrudes high and the central part is depressed, causing the flat top surface to become curved. If a vertical press is applied in this state, the above-mentioned adverse phenomena such as damage to the edges of the wet paper, or the wet paper becoming too thick, may be aggravated, or the wet paper This may cause twisting or wrinkles.

Therefore, the present invention relates to a separator devised for the purpose of flat-top dehydration of rectangular wet papers such as the above-mentioned TEX, and effectively solves various problems when dehydrating the same wet papers mentioned above. It was provided as a gift.

That is, in the present invention, when a large number of thick rectangular wet paper papers 1 such as TEX are stacked flat and dewatering is attempted by applying vertical press from above and below, the present invention can be used to stack rectangular wet papers 1 with a flat screen as shown in FIG. The four sides of the rectangular screen 6 are framed with a rectangular frame 8 made of flat edge plates 7 to form a dewatering separator 9, and the size of the separator 9 is set as above. The separator 9 is set to extend outward from the periphery of the rectangular wet paper paper 1, and the separator 9 is interposed between each of the rectangular wet paper papers 1 stacked flat to perform the dehydration. It is something that

Each separator 9 may be placed on top of each sheet of rectangular wet paper 1 that is stacked.

In the above manner, if the separator 9 is stacked on top of each rectangular wet paper 1 using the rectangular frame 8 larger than the wet paper 1 as a guide, each rectangular wet paper 1 can be reliably placed within the rectangular screen 6. I can do it.

In addition, the rectangular frame 8 applies appropriate tension to the screen 6 due to its own weight in the outer area of the stacked rectangular wet papers 1, and the screen 6 is interposed between the wet papers without bending or bending. It adheres tightly to the wet paper without any slippage, does not cause paper waste, and effectively prevents adhesion between each wet paper, while being able to be used for press dewatering, and also leads to dehydration moisture. be exposed.

The weight of each rectangular frame 8 is applied from the periphery of each rectangular wet paper paper 1 to each wet paper paper evenly, and in particular, the weight of each square frame 8 is applied to each wet paper paper 1 from the periphery of the wet paper paper 1.
can be resolved as much as possible.

As a result, even if a large number of thick rectangular wet paper papers 1 are stacked flat, the flat top surface can be kept substantially flat, the press dewatering can be carried out properly, and the cause of wrinkles and damage to the wet paper paper can be eliminated. .

Furthermore, since the rectangular frame body 7 is composed of flat edge plates 7,
This can be used as a suction surface of a robot's suction cup, and it is also useful for automating this process without having to manually place a separator 9 each time a sheet of wet paper 1 is stacked.

FIG. 6 shows that, in order to accurately carry out suction movement using the suction cup of the robot, there are preferably four
A case in which three suction target discs 10 are provided will be exemplified.

The rectangular frame 8 and the rectangular screen 6 may be bordered by bonding or by making each edge plate 7 of the frame 8 double and sandwiching the screen 6 between them.

Furthermore, it is desirable that both the frame body 8 and the screen 6 be made of synthetic resin material in order to improve their suitability for the above-mentioned purpose of the article.

Further, as the screen 6, a braided net or a porous sheet can be used as long as it is a net-like material.
