Vacuum adsorption device of blanking press line unloader

摘要

The present invention provides a suction force to a plurality of suction cups by using a small number of vacuum generators in the blanking unloader of the blanking press line, and is located on the base plate side to increase the unloader's operational stability and the unloader's operation management efficiency. Mounted on the movable member 9, the link member and the actuating rod actuated by the dynamic movement of the movable part 9, the link member 10 and the actuating rod 11, and move back and forth and up and down, and transmit the dynamic displacement to the gripper side. In the unloader device composed of a moving frame 12 and a gripper unit coupled thereto, a vacuum generator 20 is installed at a position of the unloader unit, and a vacuum line is opened from the vacuum generator 20. The vacuum suction of the blanking press line unloader for supplying the vacuum generator side vacuum suction force to the suction cup simultaneously by connecting a plurality of suction cups 16 to the vacuum line. Device.
