Abstract

PURPOSE:To exactly superpose and position a plate and to improve the accuracy of simultaneously working of two pieces by sucking and holding the bottom face of a first plate supplied to a work stable by a carrying device in a prescribed position, carrying the next plate, and positioning it on the first plate. CONSTITUTION:With respect to plates W loaded on a pallet 29, one piece is sucked by a vacuum pad 61 of a carrying device 3 and carried onto a work table 9. Subsequently, by a sucking device 13 installed on the lower face of the work stable, the bottom face of the plate is sucked and held. Next, a second plate W on the pallet 29 is sucked and carried onto the work table 9. A second plate W is positioned and superposed on a first plate by the same method as a first plate W. In this case, since a first plate W is sucked and held from the lower face, it does not move even if an action at the time when a second plate W is superposed is received, and the latter is superposed exactly on a first plate.

Detailed Description of the Invention [Objective of the Invention] (Industrial Field of Application) This invention relates to a sheet material polymerization method and apparatus for a sheet processing machine, such as a turret punch press, a laser processing machine, etc. It can be used in a plate processing machine that superimposes two sheets on a work table and subjects them to predetermined processing.

(Prior Art) In a plate material processing machine such as a turret punch press, the plate material is fed one by one onto the upper surface of a work table, and press processing is performed while controlling the movement by using a clamp.

(Problems to be Solved by the Invention) In such processing of each plate, there is a limit to processing efficiency and it is difficult to increase productivity. For this reason, the present invention provides a suction means for the plate material on the underside of the work table to prevent the plate material from moving after the plate material is supplied from the plate pallet onto the work table by a conveying device and positioned. The board is held by suction. Subsequently, the second plate material is superimposed on the first plate material on the work table from the plate pallet, and press working is performed in a two-ply form, with the aim of performing highly efficient and accurate processing.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides a work table that supports two plates in a superposed manner and processes the two plates while holding and transporting them with a clamp.

The present invention also provides a work table for processing two plates while supporting them in a superposed manner and transferring them while being held between clamps, a conveying device for conveying plates from a pallet of plate materials onto the work table, and a conveying device for conveying plates from a pallet of plate materials onto the work table. A sheet material polymerization device for a sheet material processing machine was constructed by including a suction means for suctioning and holding the bottom surface of the first sheet material in a fixed position.

(Function) A transport device picks up one of the plates loaded on the pallet from above and transports it onto the work table. This plate material is held by suction on the bottom surface of the plate material by suction means attached to the lower surface of the work table. Next, the next two plates on the pallet are sucked and conveyed onto the work table. This second board is positioned and superimposed on the top of the first board in the same manner as the first board, but at this time, since the first board is held by suction from the bottom, the second board is Even when the first plate material is subjected to the action of polymerization, it does not move and is accurately polymerized onto the first plate material.

The two vertically stacked plates are simultaneously clamped by the clamp of the plate processing machine, and then released from the suction means and the conveying device. The two plates are transferred in a stacked manner on a work table while being held by clamps, and undergo a predetermined process.
