Abstract

PURPOSE:To securely lift up laminated plate-shaped bodies successively one by one from the uppermost layer by lowering a lifter and by hooking and floating up the side peripheral parts of the plate-shaped bodies in the uppermost layer with the sawtooth part of a floater, and by attracting it by an attractor, and while slinging by conveying it to a transportation rolls. CONSTITUTION:A lifter 1 is lifted up, and the sawtooth part of a floater 3 is abutted on the side peripheral parts of the stacked PVC laminated steel plates A in the uppermost layer, and then the lifter 1 is lowered. Then, one to three sheets A-1 to A-3 of the stacked PVC laminated steel plates A in the uppermost layer in the side peripheral part thereof are hooked by the sawtooth part 31 of the floater 3 on which the steel plates are abutted and are floated up. Then, while floating the side peripheral part of the PVC laminated steel plates A, an attractor 2 is lowered to attract and float up the uppermost layer steel plate A-1. The steel plate A-1 is attracted to the underside of four groups of magnet-made transportation rolls that are arranged in parallel to a flow line 4, and is fed to nip rolls (not shown) by rotating a transportation roll 4-1.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically transporting plate-shaped bodies, and more specifically, it automatically transports plate-shaped bodies that are cut into a predetermined size and stacked on a flow line leading to a secondary processing step. On how to do.

[0002]

2. Description of the Related Art Conventionally, when a large number of steel plates or plastic laminated steel plates, which have been cut into a predetermined size and stacked, are transferred to the next step one by one, the plates first loaded on the lifter. The floater made of a magnet is brought into contact with the side portion of the plate-like body at the upper end of the plate-like body, and the plate-like body is adsorbed by an adsorber such as an air pad while repelling and separating the plate-like bodies by magnetic force, and the plate-like body is removed. The method of transferring to the carrying roll of the next process while lifting was adopted.

Further, when the plate-like body is a plastic plate or a non-ferrous metal plate, the magnet floater has no effect. Therefore, a suction plate of an adsorber is directly applied to the plate surface and is suspended and transferred. Was taken.

However, in any of the above methods,
Since the plate-like bodies on which a large number of sheets are stacked are in close contact with each other, it is difficult to hang them while surely separating them one by one. It also caused blanking and caused troubles in the automatic transfer process.

SUMMARY OF THE INVENTION The present invention is an automatic transfer method for solving the above-mentioned problems, and the gist thereof is one by one from the uppermost layer of a large number of plate-like bodies loaded on a lifter. In the method of suspending and automatically transporting, the sawtooth portion of the floater having a sawtooth portion is brought into contact with the side edge portion of the uppermost layer of the stacking plate member on the lifter, and the lowermost layer is accompanied by the lowering of the lifter. The method for automatically transporting a plate-shaped body is characterized in that the side edge of the plate-shaped body is hooked on the sawtooth portion of the floater and floated, and is adsorbed by an adsorber and suspended and transferred to a transfer roll.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. FIG. 1 is a side view of a transport device used in an embodiment of the present invention with a part thereof omitted, and FIG.

As shown in a partially omitted side view in FIG. 1, an automatic carrier used in the present invention is a lifter 1 which can be raised and lowered in the directions of arrows X-1 and X-II, and a plate loaded on the lifter 1. A floater 3 having a sawtooth portion 31 is fixedly arranged at a position where side portions of the strips A-1, A-2, A-3, etc. come into contact, and a transport roll is provided above the stacking plate A. 4-1
Are supported by support portions 22 on both sides of the flow line 4 arranged in parallel with each other, and can be moved up and down in the directions Z-1 and Z-2 and have a suction cup 21 at the lower end. Are arranged in large numbers.

An embodiment of the present invention using the above automatic carrier will be described below. First, after loading a large number of rectangular polyvinyl chloride laminated steel sheets (hereinafter referred to as "PVC laminated steel sheets") A on the lifter, the lifter 1 is moved to the arrow X-
When the saw tooth portion 31 of the floater 3 is brought into contact with the side edge portion of the uppermost layer of the loaded PVC laminated steel sheet A and then the lifter 1 is lowered in the arrow X-2 direction, the cross section is shown in FIG. As shown in the figure, one to three sheets (A-1 to A-3) of the uppermost layer in the side portion of the stacked PVC laminated steel sheet A are caught on the sawtooth portion 31 of the abutting floater 3 and float up. .

As described above, while advancing the side portions of the PVC laminated steel sheet A, the adsorber 2 group is lowered in the direction of arrow Z-2 to adsorb onto the uppermost PVC laminated steel sheet A-1, and then the arrow Z. -1 direction, the PVC laminated steel sheet A-1 is adsorbed on the lower side of the magnet-made conveying rolls 4 arranged side by side in the flow line 4, and the conveying rolls 4-1 are rotated in the arrow direction to laminate the PVC. While the steel plate A-1 is fed into the nip roll 5 and conveyed in the direction of the arrow Y, the lifter 3 is moved up and down to bring the side edge portion of the PVC laminated steel plate A-2 into contact with the floater 3 so that the floater 3 floats. It is possible to automatically convey the sheets one by one.

The floater 3 may be made of any material as long as the contact surface with the PVC laminated steel plate A has a saw-tooth shape, but it is even more effective if it is a magnet, and is in a direction orthogonal to the flow line 4. In addition to the case where only the floaters 3 provided with the sawtooth portions 31 are arranged at a predetermined interval, a conventional magnet floater and the above-mentioned floaters 3 are alternately arranged and used, and the like can be appropriately selected.

In the above-mentioned embodiment, the plate-like object to be conveyed is PV.
Although the case of the C laminated steel plate is shown, when automatically transporting a plastic single plate or a non-ferrous metal plate, the flow line connects the line connecting the upper surfaces of the transfer rolls 4 in FIG. The adsorbers 2 are arranged side by side on the flow line while being aligned on the same plane, and the stacking plate A
Disposing the lifter 1 and the floater 3 on which is mounted, the plate-shaped bodies A that have been sucked and picked up one by one by the adsorber 2 group and placed on the upper side of the conveying roll 4 group and sequentially conveyed to the flow line 4 You can

[0012]

Since the present invention has the above-mentioned structure, it has the following effects. That is, according to the present invention, the side portions of the stacked plate-shaped bodies can be hooked by the sawtooth portion of the floater and floated one by one, so that the adhesion between the stacked plate-shaped bodies is released.
It can be lifted up by an adsorber without resistance, and it is not possible to adsorb as in the conventional case, resulting in no blanking or accompanying lifting of two sheets together, so that each sheet can be transported reliably and smoothly.
