[Industrial applications]

[0003]

2. Description of the Related Art A conventional laminated plate-like object separating and conveying apparatus is provided with a roller at the uppermost stage of laminated plate-like objects such as papers as disclosed in Japanese Patent Laid-Open No. 2-8147. The roller is rotated while the roller is pressed against the uppermost stage of the plate-like material, and the plate-like material is fed out while sliding one by one.

[0004]

The above-mentioned prior art has a problem that the surface of the plate-like object may be damaged because the plate-like object is fed out while sliding. Also, when the pressing force of the roller is too strong, or when the surface of the plate-like object is charged with static electricity, the plate-like object in the uppermost stage and the plate-like object in the lower stage in contact therewith are closely attached and separated. Since it is difficult, there is a problem that two or more plate-like objects are sent out.

It is an object of the present invention to provide a highly versatile laminated plate-like object separating and conveying apparatus capable of surely separating the laminated plate-like objects one by one without damaging the surface thereof. is there.

[0006]

In order to achieve the above object, a laminated plate-like object separating and conveying apparatus of the present invention is provided with a supply table for loading laminated plate-like objects and a laminated plate-like object. To blow the air to the side surface and separate the uppermost plate from the lower plate, an air nozzle provided near the side of the uppermost plate and the uppermost plate separated from the lower plate In order to grip the plate-shaped object, it is composed of a gripper that can be located above the plate-shaped object.

The laminated plates may be placed directly on the supply table or may be placed in a storage cassette arranged on the supply table. When the storage cassette is used, either the bottom or the top of the supply table is provided with a convex portion and the other is provided with a recess for fitting with it, whereby the storage cassette is arranged at a predetermined position on the supply table. It is preferably configured to. Further, it is preferable to provide a regulation plate for preventing the lateral displacement of the stacked plate-like objects on the supply table or the storage cassette. As the gripper, a suction gripper, an air blowing type non-contact gripper, or the like can be used.

The air nozzle preferably comprises an ion generator for ionizing the air to be blown out. Further, the first air nozzle for blowing air with the strength required for separating the uppermost plate-like object and the strength required for the gripper to grip the separated plate-like object are weaker than the above strengths. It is preferable to provide two types, that is, a second air nozzle for blowing air. It is also possible to change the strength of the air to be blown without providing such two kinds of air nozzles.

Further, in the laminated plate-like object separating and conveying apparatus of the present invention, the height of the uppermost plate-like object is increased every time the laminated plate-like objects are continuously separated and conveyed one by one from the uppermost step. It is preferable that the height relationship of the air nozzles, and the height relationship of the gripper, if necessary, are matched. Therefore, it is preferable to provide a correction mechanism for correcting the relative position of the supply table and the air nozzle each time one of the stacked plate-shaped objects is separated. This correction mechanism may raise the height of the supply table or may correct the position of the air nozzle. In this case, a mechanism for detecting the height of the uppermost stage of the plate-like object may be provided, and the plate-like object supply table may be raised or the position of the air nozzle may be corrected until the detection mechanism detects the plate-like object. .

[0010]

In the laminated plate-like object separating and conveying apparatus for sequentially separating and conveying the laminated plate-like objects one by one from the uppermost stage, the plates are ejected from the air nozzles provided near the side surfaces of the uppermost stage of the laminated plate-like objects. By blowing air on the side surface of the object,
An air film is formed between the uppermost plate-like member and the lower plate-like member in contact therewith, and the two can be separated. Then, by using the grip board, only the uppermost plate-like object can be gripped from above. In addition, in the case where two systems of this air nozzle are provided, they are divided into those for separating the plate-like object in advance before gripping and those for separating during the gripping to improve the reliability of single-piece separation gripping. It is possible to shorten the separation time for one sheet.

When the gripping disc is a suction gripping disc, for example, when the plate-like object is a porous plate, suction force is generated from the holes inside the porous plate, so that a large number of plate-like objects are adsorbed at one time. Resulting in. When the air-blowing non-contact gripping board is used, the air blown from the holes hits the porous plate on the lower surface to generate a separating force, so that the reliability of the single-piece separating and gripping can be improved.

In a device provided with a mechanism for correcting the stacking height of the plate-shaped objects for each separation, it is possible to continuously perform the operation of separating and grasping one plate. Further, by spraying the ionized air by the ion generator provided immediately before the air nozzle onto the side surface in the vicinity of the uppermost stage of the stacked plate-like objects, it is possible to reliably separate the charged plate-like objects that are difficult to separate. .
