BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punch press and, more particularly, to an apparatus for carrying a product out of a table.

[0002]

2. Description of the Related Art As a device for carrying out products to the outside of a table in a punch press, there is known a device in which a plurality of carrying rollers are provided on a carry-out side table so as to be rotatable in a carry-out direction. In this device, the product separated from the plate material is positioned on a plurality of transport rollers, and by rotating the plurality of transport rollers in the unloading direction, the product can be transported to the outside of the table. is there.

[0003]

However, as described above, in a device for unloading a product in a punch press, the product is positioned on the table until the product is separated from the plate material and then unloaded out of the table. Therefore, the next positioning of the plate material cannot be performed, and the time during which a series of processing of the plate material is interrupted becomes longer, resulting in a problem that work efficiency is deteriorated.

[0004]

As described above, in order to solve the conventional problems, in the present invention, a table for supporting a plate material movably in a horizontal direction is provided, and the plate material supported by the table is provided. In order to position the plate material processing portion at a predetermined position, a carriage provided with a plurality of work clamps for clamping an end portion of the plate material is provided so as to be movable in a horizontal direction approaching and moving away from the plate material processing portion, and a position above the table from the plate material. Provide a conveyor device to transport the separated products,
The conveyor device is configured such that one end side is located near the plate processing portion and the other end side of the conveyor device is located outside the table, and further, a plurality of products holding the product from above in the vicinity of the plate processing portion. A holder support member provided with a holder is provided, and in order to transfer the product held by the plurality of holders to the conveyor device, the holder support member can be moved in the horizontal direction, can be moved up and down, and about the vertical axis. It is characterized by being rotatable.

[0005]

According to the above construction, the holder supporting member is lowered to hold the product from above by the plurality of holders. Next, the holder support member is moved in the horizontal direction away from the plate material processing portion, and the product is completely withdrawn from the plate material processing portion. Then, the product is lifted by raising the holder support member, and the product is positioned above one end side of the conveyor device by rotating the holder support member about the vertical axis. Then, the holding state of the product and the holder is released, and the product is transferred to one end of the conveyor device. Furthermore, the product is transported by driving the conveyor device,
Take it out of the table.

Here, a conveyor device is provided at a position above the table, and one end of the conveyor device is located near the plate material processing section, and the other end of the conveyor device is located outside the table. The holder support member provided with the holder is configured to be movable in the horizontal direction, capable of moving up and down, and rotatable about a vertical axis, so that even before the product is carried out of the table, a plurality of holders are supported. When the holder supporting member is raised in a state where the product is held, the product does not remain on the table. Therefore, even before the product is carried out to the outside of the table, the carriage is moved in the horizontal direction approaching and separating from the plate material processing section under a state where the end of the plate material is clamped by the plurality of work clamps, The next positioning of the plate can be performed.
