发明名称 Device for controlling grippers engaging sheet-like workpieces at an infeed station of a processing machine
摘要 A device for controlling the gripping action of grippers on a plate-like workpiece at the end of the feeding table of a machine that processes sheet-like workpieces has an arrangement for controlling the upper mechanisms for positioning, respectively, the gripper bar, the sheet pull-down appliance, and a stop-carrying tablet and a mechanism for opening the grippers. This device includes a horizontal common axle arranged to extend crosswise to the sheet travelling direction and mounted for rotation around its lengthwise axis so as to be able to be oscillated through a predetermined angle by a single lower drive arrangement consisting of a cam, a lever follower and a pull linkage. Each lateral end of this common axle carries a symmetrical series of articulated arms and cam which actuate the above-mentioned upper mechanisms.
