Abstract

PURPOSE:To reliably suck a number of loaded coupling materials one by one without the occurrence of a miss in suction and to improve the operation rate of a device. CONSTITUTION:A plurality of suckers 11 are located such that only the approximately central part of a number of coupling materials loaded on a loading plate 2 is sucked to the under surface of an elevable sucking board 3. Through lowering of the sucking board 3, the coupling material is sucked through the suckers 11 and thereafter the sucking board 3 is raised. Only the central part of the coupling material only the approximately central part of which is sucked by the suckers 11 is raised at a moment when the sucking board 3 is raised and the two end sides are curved. Thereby, curving of the coupling material causes the topmost coupling material to be released and separated away from a subsequent lower coupling material, and only one coupling material is raised in a sucked state.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a suction device used for attaching a sheet-like connecting material made of, for example, kraft paper to a plurality of tiles and connecting the plurality of tiles to each other, and particularly to a suction device used for connecting the plurality of tiles to each other. This invention relates to a suction device that suctions materials one by one.

0002

[Prior art] In order to perform tile construction simply and quickly,
It is widely used that a plurality of tiles are connected to each other by a connecting material such as kraft paper, and the plurality of tiles are made into a unit. The process of connecting tiles using the connecting material includes first a step in which a plurality of connected materials loaded one by one are adsorbed one by one using a suction device, and a predetermined number of the connected materials adsorbed by this suction device are arranged on a horizontal plane. The method generally consists of the process of attaching the tile to the back side of the tile. Therefore, a conventional suction device for suctioning the above-mentioned connecting material will be briefly described below.

This adsorption device 50, as shown in FIG.
A loading plate 51 on which a large number of connecting materials C are loaded, a suction cup 52 provided above the loading plate 51 and movable up and down by a lift drive unit (not shown), and a suction cup 52 on the lower surface of the suction cup 52. This includes a plurality of suction cups 53 formed therein. Note that the loading plate 51 has positioning rods 54 and 55 for positioning a large number of connecting members C.
has been planted. On the other hand, the suction cup 52 has insertion holes 56 and 57 through which the positioners 54 and 55 are inserted when the suction cup 52 is lowered. In addition, the suction cup 53 formed on the lower surface of the suction cup 52 is arranged so as to suck almost the entire surface of the connection material C, as shown by ● in FIG.
A plurality of them are formed corresponding to the shape of.

In the conventional suction device 50 configured as described above, the suction cup 52 is driven downward by the drive of an unillustrated elevating drive unit, and the plurality of suction cups collect the connecting materials C loaded in large numbers. Substantially the entire upper surface is suctioned and held on the suction cup 52 by the plurality of suction cups 53, and is then driven upward. The connecting material C thus suctioned and held is moved onto a predetermined number of tiles arranged in a row by a horizontal drive unit (not shown), and is moved to the pasting process of the connecting material C.

[0005]

However, in the conventional suction device 50, when the connecting material C is sucked by the suction cup 53 and then driven upward by the lifting drive section (not shown), the connecting material C loaded in large numbers is removed. The best connecting material C
Not only, but also up to the second or third connecting material C from the top,
In many cases, they increase at the same time, resulting in an extremely low operating rate. In particular, when the connecting material C is made of a thin paper material such as kraft paper or cloth paper, a plurality of connecting materials C are often lifted at the same time. This is because the upper and lower connecting materials C may stick to each other at the cut portion due to burrs, etc. that occur when manufacturing the connecting material C by cutting a large number of sheets of paper into the shape shown in Figure 9, or the upper and lower connecting materials C may have high air permeability. In cases where the connecting material C is formed of kraft paper,
This is because the loading position of the connecting material C is slightly misaligned.

Therefore, the present invention was proposed in order to solve the problems of the conventional suction device described above. The object of the present invention is to provide an adsorption device that can improve the operating rate.

[0007]

[Means for Solving the Problems] The present invention has been proposed to achieve the above object, and is a suction device that suctions sheet-like connecting materials that connect a plurality of tiles one by one. A stacking plate on which a plurality of the above-mentioned sheet-like connecting materials are stacked, a suction cup provided above the stacking plate and at least movable up and down, and a suction cup provided on the bottom surface of the suction cup. The present invention is also characterized in that it includes a plurality of suction cups that suck only approximately the central portion of the upper surface of the connecting material loaded on the loading plate.

[0008]

[Function] According to the suction device of the present invention, a large number of sheet-like connecting materials stacked on a stacking plate can be moved only approximately at the central portion of the connecting materials by a plurality of suction cups provided on the lower surface of the suction plate. is absorbed and raised. At this time, the above connecting material is
Since only the central part is suctioned by multiple suction cups,
When the suction cup is raised, first only the central part is raised, and then the other parts are raised later. That is, at the moment when the suction cup is raised by this suction device, the connecting material suctioned by the plurality of suction cups is bent. Therefore, even if the topmost connecting material and the connecting material loaded below this connecting material are attached to each other due to burrs generated during cutting, the curvature of this connecting material will cause the topmost connecting material to The connecting material stacked below the connecting material is detached and separated from the uppermost connecting material, and only the uppermost connecting material is attracted and raised.

[0009]

At this time, the kraft paper C1 is only held approximately at the center by the plurality of suction cups 11, and both ends are free ends, so when the suction cup 3 is raised, the kraft paper C1 is Only the central part is raised and then the other parts are raised later. That is, at the moment when the suction cup 3 is raised by the suction device 1, both ends of the kraft paper C1 suctioned by the plurality of suction cups 11 are curved. Therefore, there is a possibility that the topmost kraft paper C1 loaded on the stacking plate 2 and the kraft paper C2 loaded below this kraft paper C1 are stuck to each other due to burrs etc. generated during cutting. However, due to the curvature of the kraft paper C1, the kraft paper C2 stacked below the top kraft paper C1 is always separated from the kraft paper C1, and as shown in FIG.

The kraft paper C that has been suctioned by the suction device 1 in this way is moved by the sliding mechanism (not shown) in which the slide plate 14 is horizontally slid along the two slide shafts 14a, 14a, and the kraft paper C is The process moves on to pasting paper C onto a predetermined number of tiles.

Therefore, according to the suction device 1 according to the first embodiment configured as described above, a large number of kraft papers C stacked on the stacking plate 2 are reliably suctioned one by one. The operating rate can be greatly improved because the process is carried out in the next step.

Next, an adsorption device according to a second embodiment of the present invention will be explained.

, 6, 7, and 8 are entirely curved upward. Therefore, even if a large number of sheets of kraft paper C are attached to each other due to burrs or the like during molding, they are separated from each other by being set on this stacking plate 2.

[0020] By the operation of this adsorption device 20,
When the suction cup 3 is lowered by the driving of the two air cylinders 15 and 16, the plurality of suction cups 11 provided on the lower surface of the suction cup 3 move the topmost kraft paper loaded on the loading plate 2. Adsorbs C. At this time, the kraft paper C is curved by the step members 21, 22, 23, and 24 so that only the periphery of the two pairs of positioning rods 5, 6, 7, and 8 bulges upward, as described above. , the plurality of suckers 1
1 is securely abutted against this curved portion. and,
At the moment when the suction of the kraft paper C by the suction cup 11 is completed and the air cylinders 15 and 16 are again driven and raised, the topmost kraft paper C is removed from the suction cup 11 as explained in the first embodiment. The portions other than the adsorbed portions are curved, and the kraft paper C stacked below the uppermost kraft paper C is separated.

[0021] Furthermore, the air cylinders 15, 1

As described above, in the suction device 20 according to the second embodiment, there are a stage in which the kraft paper C is set on the stacking plate 2, a stage in which it is sucked by the suction cup 11, and a stage in which it is raised after being sucked. Since only one sheet of kraft paper C is lifted up in the three steps and transferred to the next step, the suction can be carried out more reliably without causing suction errors than in the suction device 1 according to the first embodiment. Only one sheet of kraft paper C can be transferred to the next process, resulting in an extremely high operating rate.

Furthermore, in the suction device 20 according to the second embodiment, the step members 21, 22, 23, 2
4 are provided, and the suction of the kraft paper C by the suction cup 11 is performed using these step members 21, 22, 23, 24.

For example, it may be one that adsorbs other connecting materials such as cloth paper.

[0025]

Effects of the Invention As is clear from the description of the above embodiments, according to the suction device according to the present invention, only the approximately central portion of the connecting material is removed by the suction cup provided on the lower surface of the suction cup. Since the connecting member is attracted and raised, first only the central part is raised, and then the other parts are raised later, and the connecting member is curved at the moment of raising. therefore,
Even if the topmost connecting material and the connecting material loaded below this connecting material are attached to each other due to burrs generated during cutting, the curvature of this connecting material will cause the topmost connecting material to The connecting material stacked below the material can be effectively separated from the uppermost connecting material, and only one connecting material can be reliably adsorbed.
