BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material peeling device for peeling a large number of works loaded on a carrier, for example, one by one.

[0002]

2. Description of the Related Art Conventionally, a magnetic separation device or an electromagnetic separation device is applied to the ends of accumulated and stored works to separate the first work and the second work or less. However, in both cases, the ends of the stacked works are held by a stopper, and the works are not held together when the separating device is released.

[0003]

However, in the conventional method,
With this type of technology, the first piece is held by a vacuum pad.
Since it is adsorbed, there is no problem, but if the separation device is released when the first work piece is peeled off, the second work piece will be connected and it will deviate from the third work piece and below, so it must be readjusted each time. I had to do it.

Further, when the electromagnetic floater is used, the coil cannot be wound because of its small volume, so that the directional magnetic flux cannot be generated.

Further, the distance at which the separating device is separated and the influence of the magnet is eliminated varies depending on the plate thickness. Therefore, there is a problem that it is difficult to set the timing for releasing the stopper.

In order to solve the above-mentioned problems, an object of the present invention is to remove the first accumulated work piece,
(EN) Provided is a plate material peeling device which prevents the second sheet from being shifted from the third sheet and below and eliminates the trouble of re-adjusting each time, thereby saving wasteful time.

[0007]

In order to achieve the above object, the present invention is a plate material separating device for separating laminated plate materials one by one, and a loader having a suction device attached to the tip thereof is used as a guide rail. Fix and attach the lifting cylinder device to this guide rail, and also install the retracting cylinder device that retracts the vertically elevated work to the side, and always use the multiple links provided in this retracting cylinder device. The work separation device is hung vertically in parallel,
A magnet was provided in this work separating device, and an air blow guide was attached to the tip of the work separating device in a vertically movable manner to form a plate material separating device.

[0008]

By adopting the plate material peeling device of the present invention, the air blow guide is placed on the work upper surface by the vertical lowering and rotation of the work separating device and moved along the work upper surface, and the work separating device is moved to the stacking work end. To stop the rotation, separate the edges of the stacked work pieces, suck the first work piece by the suction device, raise the separation device vertically above the work and retract it sideways. As a result, the second work is no longer dragged to the side.
