Abstract

PROBLEM TO BE SOLVED: To surely suck and take out only an uppermost sheet toy providing suckers sucking both ends of sheets, and pusher or retainer members below the suckers, which members push the sheet downward at inner portions thereof than portions sucked by the suckers to thereby cause generation of bend in the sheet. SOLUTION: A suction box 10 is lowered to an uppermost sheet 2 of a stock S consiting of a plurality of long continous sheets 2 to thereby make lower ends of pusher or retainer members 12 abut thereon, and under the condition, suction of the uppermost sheet 2 is carried out such that both ends of the sheet 2 are raised by suckers 11, 11. The sheet 2 between the suckers 11 and the retainer members 12 is bent 2a so that only the uppermost sheet 2 is sucked while the paper sheets 2 just below the uppermost sheet 2 are liable to be sucked to some extent at their opposed ends by the suckers 11. However, with the repelling force aginst the bending to resume the flat state of the sheets 2, namely with the elasticity of the sheets 2, the uppermost sheet 2 can be separated completely.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus capable of satisfactorily sucking and lifting sheet materials such as tile connection paper one by one.

[0002]

2. Description of the Related Art Conventionally, for example, in a suction device 51 that sucks and lifts only one of a plurality of stacked tile connection papers with a suction cup, as shown in FIG.
2 are provided with a plurality of suction cups 53, 53, 53 on the bottom side,
A suction duct 54 is connected to the upper surface of the suction box 52, and air is sucked from the suction duct 54 so that the suction
Although the tile connection paper 55 is configured to be adsorbed to the third, third, and third sheets 53, the tile connection paper 55 may be suctioned even if only one of the upper surfaces of the plurality of stacked tile connection papers is to be adsorbed.
Due to the negative pressure or static electricity generated through the gaps between the paper fibers constituting the paper, not only one sheet on the upper surface but also the paper under the upper surface are often simultaneously adsorbed.
It was difficult to adsorb 5 only.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a sheet material suction device capable of reliably sucking only one sheet.
The first gist is a device for sucking and lifting only one of the upper surfaces of a plurality of stacked sheet materials with a sucker, wherein the sucker sucks both end sides of the sheet material and the sucker sucks the sheet material. A press member that protrudes downward from the suction cup and that can press the sheet material downward inside the portion to generate a bent portion in the sheet material is provided. Also,
The second gist is that the sheet material is tile connection paper.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows nine tiles 1,1,1,1
FIG. 4 is a plan view in which the back side is connected with connecting paper, and connecting paper is
Long connecting papers 2 and 2 and a pair of short connecting papers 3 and 3
In a state where a large number of such connection papers 2 and 3 are stacked and stocked, the connection papers 2 and 3 are suctioned one by one from an upper surface by a suction device, and an adhesive is applied to the tiles 1 and 1,
The suction device has a structure as shown in FIGS. 2 and 3 and is attached to both ends of the lower surface of the suction box 10 having the suction duct 13 on the upper surface. Are provided with suction cups 11 and 11 made of rubber. The suction duct 13 is connected to a blower so as to be able to extract air, and the suction cups 11 and 11 are drawn by extracting air through the suction duct 13. It is configured to be able to suck the connection paper, and when sucking the long connection paper 2 in FIG.
Pressing members 12, 12 project downward from inside 1, 11, respectively. The pressing members 12 are formed, for example, in a resin block shape, and have a height such that they protrude further downward than the suction cup 11. So that the suction box 1
0, the suction box 10 is lowered and the lower end of the holding member 12 is brought into contact with the long connecting paper 2 on the upper surface of the stock S on which a large number of long connecting papers 2 are stacked. In this state, when suction is performed by lifting both end sides of the long connecting paper 2 by the suction cups 11, 11, the long connecting paper 2 between the suction cup 11 and the pressing member 12 is bent as shown in FIG. As a result, only one long connecting paper 2 on the upper surface side is sucked in a state as shown in FIG. 2, and the lower connecting paper 2 on the lower side is sucked up to some extent by the suction force of the suction cup 11. That is to say, the repulsive force against the bending to return to the straight state, that is, the elasticity of the connection paper tries to return to the flat state, and the paper is completely separated from the one sheet on the upper surface side. Of the stock S It becomes capable of taken out reliably adsorb only one face.

FIG. 3 is a structural view showing a state in which only one short connecting paper 3 is sucked. Similarly, both ends of the short connecting paper 3 are sucked by suction cups 11 and protruded downward to the center. The pressing member 14 applies a pressing force downward to bend the portions 3a, 3a.
a is formed between the suction cup 11 and the holding member 14, and the lower connection sheet is reliably separated by the repulsive force of the lower connection sheet against the bent portion 3a. And can be taken out by suction.

In this example, a case is shown in which only one of the upper surfaces of the stacked tile-connected papers is sucked and taken out. However, the present invention is not limited to the tile-connected papers, and also includes a sheet material such as a film. By adopting a similar structure, it is possible to reliably suck and take out only one of the upper surfaces of the stacked sheet materials.

[0007]

According to the present invention, there is provided an apparatus for sucking and lifting only one of the upper surfaces of a plurality of stacked sheet materials by means of a sucker, wherein the sucker sucks both ends of the sheet material, and the sucker sucks the sheet material. By providing a pressing member that protrudes downward from the suction cup, which can press the sheet material downward inside the portion that has been made and generate a bent portion in the sheet material, the sucked sheet material is forcibly applied. Then, the lower sheet material is reliably separated from the upper sheet material by the repulsive force against the bent portion, so that only the upper sheet can be reliably sucked and taken out.

Further, since the sheet material is the tile-connected paper, only one of the upper surfaces of the multi-layered tile-connected paper is surely adsorbed, taken out and placed on the back surface of the tile.
This has the effect that tiles can be connected by securely attaching them one by one.
