The sheet material is placed in the storage position because it is flush with the guide surface of the sheet material and has a clamping device that grips the edge of the sheet material and is capable of reciprocating in the direction along the guide surface. The sheet can be easily transported from the processing machine position to the processed sheet storage position.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

Sheet materials 1 of metal or plastic materials to be processed are deposited and stored on a sheet material mounting table 22 provided in a sheet material storage box 21 so as to be movable up and down. The sheet material 21 is raised and lowered as a feed nut 24, in which a feed screw shaft 23 fixed to the lower surface of the sheet material 21 is engaged, is rotationally driven by the motor M.

A movable guide stand 3, which also serves as a lid of the box, is provided on the top surface of the sheet material storage box 21 so as to be slidable in the horizontal direction, that is, in the left and right directions in the figure. The broken line shows a state in which the movable guide stand 3 has moved to the left and the lid of the sheet material storage box 21 has been opened.

A fixed guide stand 4 is disposed so as to be flush with the upper surface of the movable guide stand 3, that is, the guide surface, and a processing machine 6, such as a press, places its working surface 61 on the fixed guide stand 4. It is arranged so as to be flush with the guide surface. The processing machines 6 may also be printing machines for printing circuits, and these processing machines 6 are mounted on the processing table 5.

As shown in FIG. 2, a clamp relief groove 31 is formed in the guide surface of the movable guide table 3, through which the clamp devices of the supply feed device 8 and take-up feed device 9, which will be described later, run. The same applies to the fixed guide stand 4.

Reference numeral 7 designates a sheet-like material take-out device, which is composed of a vacuum suction means 73 that adsorbs the surface of the sheet-like material 1, and an elevating cylinder 71 that raises and lowers an arm 72 to which the vacuum suction means 73 is attached. When the movable guide stand 3 opens to the position shown by the broken line, the arm 72 descends and adsorbs the sheet material 1, and then the arm 72 rises, and when the movable guide stand 3 closes to the position shown by the solid line, this movable guide stand 3 The sheet material 1 is placed on top and the clamp is released.

Since the supply and feed device 8 and the take-up and feed device 9 have the same structure, only the supply and feed device 8 will be described.

A feed screw shaft 81, which is rotationally driven by a motor M and extends parallel to the guide surface of the movable guide table 3, reciprocates in the horizontal direction in which the feed screw shaft 81 extends, through a clamp cylinder 82 that is fixed to a locking nut that engages with the feed screw shaft 81. make it move.
