BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate separation device used in a plate separation and supply device.

0002

[Prior Art] In general, a sheet material separation and supply device stacks a plurality of sheets of sheet material in a storage frame, a moving body is provided above the sheet materials so as to be movable up and down, and a suction pad is provided at the bottom of this moving body. The movable body is lowered to pick up the top stacked plate with a suction pad, the movable body is raised, and the movable body is then moved laterally to supply the plate to a plate processing machine such as a press machine. It is something to do.

[0003] When these boards are lifted up by adsorption with a suction pad, the boards may come into close contact with each other due to the oil film of anti-corrosion agents, etc., and two boards may rise together. A plate separating device is provided for separating the plates.

Conventionally, various types of plate separation devices have been proposed, but all of them have a pair of separating claws disposed above the storage frame, and the movable body is raised to the height of the separating claws and then stopped once. The structure is such that a separating claw is inserted between two plate materials that have been raised to overlap and protrude, causing the lower plate material to fall.

[0005]

[Problems to be Solved by the Invention] In the conventional plate material separation device, as mentioned above, the moving body must be raised and stopped at a height where the separating claw protrudes and can be reliably separated. Indeed, high precision is required to control the movement of a moving object. Therefore, an expensive moving body control cylinder or the like is required.

Furthermore, even if the precision of movement control is improved, if the machine body or plate is tilted or distorted, the position of the separating claw relative to the plate will shift, so the position of the separating claw must be finely adjusted one by one. However, there was a drawback that the plates could not be separated and dropped reliably.

The present invention solves these problems and provides a highly practical plate separation device.

[0008]

SUMMARY OF THE INVENTION The gist of the present invention will be explained with reference to the accompanying drawings.

[0013]

[Embodiment] In this embodiment, several storage frame rods 7 are erected on the machine base 6, and a large number of thin plates 1 are piled up inside the storage frame rods 7. The board is suctioned up one by one starting from 1a, and the highest board 1a is always placed on the moving body 2.
In order to match the lowered position of the suction member 3, the height position of the uppermost plate 1a is detected by a sensor, and the drive motor 8 rotates the screw rod 20 to drive the bottom table 11 upward.

In this embodiment, a movable body 2 is disposed above the stacked plates 1, and a pair of suction members 3 are vertically disposed on the movable body 2.

A slide fitting groove 9 is formed in the movable body 2, and a pair of mounting rods 10, 10 are fitted into the slide fitting groove 9, facing each other on the left and right sides of the outer sides of the suction members 3, 3. At the lower ends of the mounting rods 10, 10, sharp separation claws 4, 4 are attached so as to be slidable and protrude toward the sides of the plate material 1, respectively.

Positioning member mounting rods 12, 12 are horizontally protruded inwardly at intermediate positions of the respective mounting rods 10, 10, and the tips of the positioning member mounting rods 12, 12 are provided with a protruding degree. Spiral-shaped positioning members 5, 5 for adjustment
The screws protrude and hang down.

In this embodiment, the protrusion degree is adjusted by screwing the positioning member 5 according to the thickness of the plate material 1 to be used.
Slide and adjust the mounting rods 10, 10 according to the width dimension of the slider, and adjust in advance so that the separating claw body 4 can always protrude at the correct position, to ensure that the overlapping lower plate material 1b is separated and dropped I'm trying to make it possible.

The separation claw body 4 of this embodiment will be described in more detail.

When the movable body 2 is raised and moved laterally, the lower plate material 1b that has been protruded and overlapped falls back into the space between the storage frame rods 7. The top plate material 1a whose tip side surface 4' is sucked by the suction member 3
abutting against the side surface 1a' of the other separating claw body 4, and abutting the abutting end side surface 4' of the other separating claw body 4 against the side surface 1b' of the lower plate material 1b,
The lower plate material 1b is positioned to slide relative to the plate material 1a, and a downwardly tapered surface is formed below the abutting end side surface 4' of one separation claw body 4 that abuts against the side surface 1a' of the plate material 1a. 13 is formed.

Therefore, when the separating claws 4 protrude from the left and right sides, the lower plate 1b slides with respect to the upper plate 1a, and the sliding edge 1b'' of this plate 1b abuts against the downwardly tapered surface 13. and this downwardly tapered surface 13
The plate material 1b is slightly bent downward due to the pressure.

This deflection weakens the adhesion of the plate material 1b and causes it to fall downward; however, in this embodiment, in order to further ensure this separation and fall, a gap is formed between the plate material 1b and the upper plate material 1a due to the deflection of the plate material 1b. An air nozzle 14 for jetting air toward the separating claw body 4 is provided.

Therefore, in this embodiment, the movable body 2 descends, the suction member 3 of the movable body 2 attracts the plate material 1a, and rises, and before moving laterally, the left and right separating claws 4 protrude inwardly. Air is ejected from the air nozzle 14, and the plate material 1a
Even if the lower plate material 1b is tightly polymerized, it is reliably separated and dropped between the lower storage frame rods 7, and the plate materials 1 can be supplied one by one.

In the drawing, reference numeral 15 is a vertical movement cylinder device for the moving body 2, 16 is a vertical movement guide, 17 is a lateral movement mechanism for laterally moving the moving body 2, 18 is a transfer/falling part for the plate material 1,
Reference numeral 19 is a transfer belt that transfers and supplies the plate material 1 that has been transferred and dropped.

[0024]

Effects of the Invention As described above, the present invention always brings the positioning member into contact with the top surface of the plate when suctioning the plate, so as in this embodiment, one of the separating claws is attached to the side surface of the upper plate. , the ejecting operation is performed at a preset accurate position, such as by accurately abutting the other separating claw against the side surface of the lower plate material to be overlapped, or by accurately inserting and protruding the separating claw between the two plate materials. Even if the aircraft is tilted or the plate material is bent or distorted, the separation claws will always be located at the correct position without malfunctioning like in the past, and without the need for highly accurate and expensive cylinder devices. This is an extremely practical plate separation device that can move the body in a protruding manner to reliably transfer one plate at a time.
