The operation will be described based on the above configuration.

A plate material processing machine having a numerical control function such as a laser processing machine, a punch press machine, etc., which has undergone microjoint-less processing such as cutting and drilling, and has separated skeletons into semi-finished products (parts) W1 to Wn. The vacuum pad of the take-out loader TL and the electromagnetic magnet 6 suck and hold from the table T of the sheet material processing machine, rise by the action of the elevating cylinder 7, the pinion 2 and the rack 3 mesh with each other, travel horizontally, and move above the conveyor 8. , Stops at a predetermined position, moves down to the designated position on the conveyor 8 by the positioning control function in the X-axis direction, and then places the conveyor 8 in conformity with the specifications of the next process by the positioning control function in the Y-axis direction. Stop at the position you set. The semi-finished products (parts) W1 to Wn stopped at the designated position are continuously processed by a post-process device such as a bending machine with a robot, for example.

When the transfer conveyor 8 is provided with a pusher P for positioning based on the specification of a post-process, the semi-finished products (parts) W1 to W1 which are suction-transferred by the vacuum pad of the take-out loader TL and the electromagnetic magnet 6 are transferred.

It stops at the position, and is continuously processed by a post-process device.

When the self-propelled integrated truck S is disposed behind the take-out loader TL, the semi-finished products (parts) W1 to Wn sucked and transferred by the vacuum pad of the take-out loader TL and the electromagnetic magnet 6 are taken away by the take-out loader. With the positioning control function of the TL in the X-axis direction, the TL stops at the X-axis designated position above the self-propelled integrated truck S,
Zone accumulation or box accumulation is performed at a designated position on the pallet 11 placed on the self-propelled accumulation truck S having a positioning control function in the Y-axis direction (see FIG. 3).

If the shape of the semi-finished products (parts) W1 to Wn is single, the self-propelled integrated truck S may be stopped to carry out so-called single-mounting, and in this case, the driving motor of the self-propelled integrated truck S Does not require a servo function.

Further, behind the takeout loader TL,
When the self-propelled integrated trolley S is placed,
As shown in Japanese Unexamined Patent Publication No. 73765, only a skeleton is cut off in the same manner as in the case of cutting a plurality of semi-finished products (parts) W1 to Wn with a plate processing machine, and only the semi-finished products (parts) W1 to Wn are cut off. May be a so-called nesting stack in which the stacks are placed and stacked in such a manner as to be reproduced on the pallet 11 in accordance with the boarding pattern at the time of processing the board material.

That is, for example, if the post-process is a bending machine with a robot having a manipulator function corresponding to the means of the post-process determined by the characteristics of the product, the transport conveyor 8 is arranged behind the take-out loader TL. ,
A combination of the X-axis positioning control function of the take-out loader TL and the Y-axis positioning control function of the conveyor 8 or a pusher P with an X reference stopper 9 and a Y reference stopper 10 provided on the conveyor 8.
