Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bundle cutting machine, such as a saw machine, for performing bundle cutting on a bundle plate material (a plurality of stacked plate materials), and processing of the bundle product (carry-out storage). The present invention relates to a device for performing.

[0002]

2. Description of the Related Art Conventionally, when cutting a plate material, the plate material is cut one by one by a cutting machine such as a shearing machine.

[0003]

However, when cutting a plate material one by one, the same work must be repeated for a large number of plate materials, which complicates the work and reduces efficiency. There was such a problem. On the other hand, in order to solve the above problems, it is also possible to perform bundle cutting on the bundle plate material with a bundle cutting machine such as a saw machine, but carry in the bundle plate material to the bundle cutting machine, carry out the bundle product, It is unclear how to process such as storage.

Therefore, an object of the present invention is to provide a plate material carrying-in device and a product processing device in a bunching machine capable of easily and appropriately carrying out the processing (carrying out and storing) of a bundled plate material and products.

[0005]

In order to solve the above-mentioned conventional problems, in the present invention, as a first means, a bundle product is obtained by cutting a long bundle plate material into bundles. In the take-out bunching machine, in the carry-in area located on the carry-in side of this bunching machine, a roller conveyor device is provided extending in the longitudinal direction of the bundling plate material, and this roller conveyor device is a rotary drive that supports the bottom side of the bunch plate material. A chain conveyor device comprising a plurality of possible carry-in rollers at appropriate intervals in the longitudinal direction, and a plurality of endless chains capable of traveling in the supply direction intersecting with the longitudinal direction in the vicinity of the roller conveyor device. In order to partition a plurality of mounting portions for mounting the bundling plate material on the endless chains, the endless chains are configured so that a part of each endless chain is located in the transport area. , A plurality of support rollers for supporting the side surfaces of the bundling plate members are erected at appropriate intervals on each endless chain, and when the predetermined mounting portion is positioned in the transport area, the transport rollers are mounted on the predetermined mounting portion. It is characterized in that it is provided so as to be able to project and retract with respect to the resting position.

As a second means, in a bundling machine for taking out a bunch of products by performing bunch cutting on a long bundling plate material, the bunched products are bunched in a carry-out area located on the carry-out side of the bunch cutting machine. A product carry-out device for carrying out in a direction away from the cutting machine is provided, and a product storage conveyer device for temporarily storing a large number of bundled products is provided in the vicinity of the product carry-out device. A product vise device for holding a bundled product between the device and the device is rotatable and vertically movable between a first position vertically above the product unloading device and a second position vertically above the product storage conveyor device. It is characterized by being provided.

[0007]

In the above structure, a plurality of bundled plate materials can be stored in the chain conveyor device by placing the long bundled plate materials on the plurality of mounting portions of the endless chain in the chain conveyor device. Next, by running the endless chain in the intersecting supply direction, the predetermined mounting portion is positioned in the carry-in area, and the carry-in roller is projected to the mounting height position of the predetermined mounting portion. The lower side of the predetermined bundling plate material can be supported by a large number of carry-in rollers. Then, by rotating and driving a large number of carry-in rollers, a predetermined bundling plate material is carried in to the bundling machine, and by appropriately operating the bunch cutting machine, it is possible to perform bunch cutting on the bunch plate material. , You can take out the bundled products.

After the bundled product is taken out, the bundled product is carried out in the carry-out direction by appropriately operating the product carry-out device, and the product is placed in a vertically lower position of the product vise device previously located at the first position. Then, the product vise device is lowered to sandwich the bundled product. The bundled product can be lifted by raising the product vise device while holding the bundled product in between.

After lifting the bundled product, the product vise device is pivoted from the first position to the second position. Then, by lowering the product vise device to release the sandwiched state, the bundled product can be stored in the product storage conveyor device. At this time, when the bundled product is placed on the bundled product already stored in the product storage conveyor device, the product vise device is appropriately moved up and down to adjust the height position.

When the products are to be bundled and stored in another storage section (placement section) in the product storage conveyor apparatus, the product storage conveyor apparatus is appropriately operated to move the other storage section to the vertically lower position of the second position. Position it. Then, the same operation as described above is performed.
