Abstract: To provide a controller of an automation device in a forging press capable of preventing the occurrence of a phenomenon in which raw materials are progressively transported in a partially lacked state and enhancing forging accuracy productivity, an inlet side transportation device includes a raw material detector for detecting whether a raw material to be supplied to a transfer feeder has been supplied or not and a controller for controlling the feed operation of the transfer feeder. When the controller receives a detection signal indicating that the raw material has supplied from the detector, the controller causes the transfer feeder to perform an ordinary feed operation, whereas when the controller does not receive the detection signal from the detector, the controller temporarily stops the transfer feeder at a waiting position, and when the controller receives a detection signal of a raw material supplied next within the set time of the temporary stop, the controller starts the transfer feeder, whereas when the controller does not receive the detection signal of the raw material within the set time, the controller starts the transfer feeder simultaneously with the finish of the set time.

Abstract: A transfer feeder for a forging press includes a pair of parallel feed bars (25-27) each having article-grasping claws, the feed bars (25-27) being able to make a three-dimensional movement (i.e., an advance-return movement of the feed bars (25-27) in a longitudinal direction, a clamping-unclamping movement of the feed bars (25-27) in a widthwise direction, and a lift-down movement of the feed bars (25-27)) so as to feed forging workpieces (50) from one step of a pressing process to another. The transfer feeder further includes lift-down devices each for making a lift-down movement relative to a corresponding transfer frame (21) through a lift-down linear-movement mechanism, advance-return devices each for making an advance-return movement relative to a lift-down frame of the associated lift-down device through an advance-return linear movement mechanism, and clamping-unclamping devices each for making a clamping-unclamping movement relative to an advance-return frame of the advance-return device through a clamping-unclamping linear-movement mechanism. The advance-return devices respectively include advance-return drive portions which are provided adjacent respectively to opposite ends of the feed bars (25-27) so as to feed the feed bars (25-27) in the same direction in synchronism with each other. The lift-down devices, as well as the advance-return devices, and the clamping-unclamping devices, are mounted respectively within the transfer frames (21) which are provided adjacent respectively to the opposite ends of the feed bars (25-27), and are disposed at a level higher than the feed bars (25-27).
