[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plate material processing facility including a plate material processing machine such as a punch press or a laser processing machine, and a plate material conveying device for carrying out the plate material from the plate material processing machine.
[0002]
[Prior art and problems to be solved by the invention]
Conventionally, when a plate material cut by a plate material processing machine such as a punch press is carried out from a table, the processed plate material is sucked and carried out by a suction pad of a plate material conveying device. A plurality of suction pads provided in the plate material transport device are provided with suction paths and suction sources individually, or a single suction pad is configured as a collection of many small pads. Even when this occurs, suction is possible with a suction pad corresponding to the plate material.
[0003]
However, the suction pad at a position off the plate material may suck the upper surface of the table. When the upper surface of the table is sucked in this way, the plate material transport device cannot be raised, and only the plate material cannot be sucked and lifted.
Therefore, in order to ensure that the suction pad is correctly placed on the plate material, the position of the plate material conveying device is strictly controlled in accordance with the shape and size of the processed plate material, and suction stop of the suction pad removed from the plate material is controlled. It is necessary and the control program becomes complicated.
[0004]
In order to prevent this, it has been proposed that a brush is provided on the upper surface of the table in a region near the sub head where the plate material is cut off so that the suction force does not act at a position away from the plate material. However, with a brush, there is a limit to the weight of the plate that can be stably supported.
[0005]
An object of the present invention is to provide a plate material processing facility that does not obstruct the conveyance of a plate material by adsorbing the table when the plate material placed on the table of the plate material processing machine is adsorbed by an adsorption pad.
Another object of the present invention is to make the table simple and to enable stable support of heavy plates.
Still another object of the present invention is to prevent the lower surface of the plate material from being damaged when the plate material is moved on the table.
[0006]
[Means for Solving the Problems]
The plate material processing facility of the present invention is a plate material processing facility comprising a plate material processing machine for processing a plate material on a table, and a plate material conveying device for lifting and conveying the processed plate material from the table with a suction pad. The upper surface of a part or the whole of the table is a concave / convex surface in which a plurality of concave portions or convex portions are arranged in a staggered manner and are arranged in a plurality of directions in the front / rear and left / right directions . According to this configuration, since the upper surface of the table is an uneven surface, even when an adsorption pad located in an area outside the plate material is adsorbed when the plate material on the table is adsorbed by the adsorption pad, Cause a vacuum leak. For this reason, the upper surface of the table is sucked by the suction pad at a position away from the plate material, thereby preventing the conveyance of the plate material. For this reason, it is not necessary to strictly perform the positioning of the suction pad for suction of the plate material and the suction stop control of the unnecessary suction pad, and the control becomes simple.
[0007]
In this invention, the recessed part or convex part of the table shall consist of a shaping | molding process part or perforation process part of a table top plate .
In this way, when the uneven part is a forming part or a punching part of the table top plate, the structure is simple and can be easily obtained by pressing a sheet metal, and the top plate can be replaced when damaged. Is easy to do. In addition, since it can be made from a single plate, the cost can be reduced. Further, it is possible to move the plate to the top plate of the table directly mounted to, Ru can be moved without hindrance in the case of heavy plate.
Each of the concave portions or the convex portions may have a circular or polygonal planar shape.
[0008]
In the present invention, the uneven surface is a part of the range of the table may be arranged in the plate material adsorption region by the suction pads of the work sheet conveying device. In the other range of the table, a feed smoothing component is provided for smoothing the feed of the plate material by placing the plate material by rolling contact or sliding contact.
In this way, by forming the uneven part only in the plate material adsorption area by the suction pad and providing the smoothing parts to other areas, the state of directly contacting the plate material with the table top plate is reduced, and the back surface of the plate material is damaged. Can be prevented as much as possible. A ball, roller, or brush that can rotate freely can be used for the feed smoothing part, but the ball or roller is used, and the unevenness of the table is made up of the molding processing part or punching processing part of the table top plate. When combined with the configuration, the plate material can be supported by the entire table, and stable processing and unloading can be performed even with a heavy plate material.
