As shown in the plan view of FIG. 3, a main body frame 4 consisting of a loader frame 2 and an unloader frame 3 is installed on the side of the plate processing machine 1. The plate material processing machine 1 consists of a turret punch press, and a work holder 15a that grips the plate material W on the work table 5 is attached to the front and rear (
It is installed so as to be movable laterally (in the X direction) on a carriage 15 that moves (in the Y direction).

An unloader 7 having a plurality of grippers 6 is installed on the unloader frame 3 so as to be movable forward and backward in the direction of arrow A. The unloader 7 grips the plate material W on the work table 5 with the gripper 6, and the product cart 8 shown in FIG.
Pull it up.

[0011] The product truck 8 is provided so as to be able to enter below the material truck 9, and is equipped with a pantograph type lifting platform 10. On the product cart 8 and the material cart 9, plate materials W serving as products and materials are placed via pallets 11, respectively. The material cart 9 is normally used as the work table 5 of the plate processing machine 1.
The product cart 8 is placed at a plate material placement position P adjacent to the unloader frame 3 (FIG. 3).

A rail 12 is provided on the loader frame 2 so as to project in a cantilevered manner onto the work table 5 of the plate processing machine 1, and a loader 13 is installed on this rail 12 so as to be freely movable in the direction of arrow B. The loader 13 is provided with a positioning suction pad 16 at a predetermined height approximately on the same level as the work table 5, and has a plurality of clamp devices for removably gripping a suction pad 25 that is shared with a separation device 19, which will be described later. 32 is provided on the side opposite the separating device 19. The loader 13 is equipped with a self-propelled device 14 consisting of a motor and a drive roller. The power supply line and signal line of the loader 13 are passed through a flexible cable duct 17 connected to the duct connecting base 18 of the loader 13, and connected to a control panel 34 (FIG. 4).

A board 20 of a separation device 19 is fixed to the rail 12 at a position above the end of the plate material W placed on the material cart 9, and an elevating frame 24 having a plurality of clamp devices 33 is mounted on the rail 12.
is installed on the substrate 20 via a lifting device 23. In this case, the clamping device 33 transfers the suction pad 25 to and from the loader-side clamping device 32 and grips it in a detachable manner, so that the gripping position for the suction pad 25 does not interfere with the loader-side clamping device 32. In addition, its mounting position is set higher than the loader-side clamp device 32. The elevating device 23 includes a plurality of guide rods 21 and an elevating cylinder 22.

As shown in FIG. 1, a movable roller table 26 is provided at the height of the lower surface of the positioning suction pad 16 of the loader 13, in which a number of rollers 27 are connected at both ends by chains 28 in the form of a blind. As shown in FIG. 2, the chain 28 is connected to sprockets 29 at both ends of the loader frame 2.
By driving the sprocket 29 at one end with the motor 30, the box 31 is extended horizontally from inside the box 31.
