Description

Large press material transfer system

The present invention relates to a material conveying system of a large press, and in detail, a material conveying optimized for a press process (line) of a large press for punching a plurality of materials at a time (or process unit) at once by a plurality of upper and lower molds. By using the device to transport the material at the same time to improve the material transfer efficiency and productivity significantly.

Generally, the press machine is a machine that performs plastic processing such as bending, throttling and shearing of materials by using a mold. It is a fixed bed, a slide, a frame, a prime mover, a power conducting device, etc. It is composed of: an import process for inserting the material into the mold of the press machine before and after punching (molding); a punching process for punching out the material carried into the mold; and an ejection (discharge) process for ejecting the punched material from the mold; , A press process for transferring the material taken out to the mold of the next punching process is carried out so that the press or the press process (line) adsorbs the material and then transfers, imports, exports and transfers and / or discharges the mold to the press machine. Material transfer systems are installed and used.

On the other hand, if the material is small in size and light in weight, the import, export, transfer, and discharge of the material can be achieved depending on the hand work of the worker, but many workers are required, and the worker only causes musculoskeletal disorders. In addition, productivity is greatly reduced and there is a risk of safety accidents. In some cases, high-cost articulated robots are used to achieve the import, export, transfer and discharge of press materials.

Since the articulated robot has a long arm and a large working radius, the installation distance between presses is very large, and the movement line of the material is increased between press processes, resulting in a decrease in speed and productivity, and high equipment and maintenance costs. There is a problem of poor profitability.

In addition, there is a problem that the reversal or rotation of the material to be transported in accordance with the working environment or material change, but can not respond quickly to this, there is a problem that must be replaced by one arm of the length according to the installation conditions.
