ダ速度自動制御装置。[Claims for Utility Model Registration] (1) A cylinder speed automatic comprising a sequencer in which a scheduled operating speed of an actuated object by a cylinder is programmed, and a hydraulic circuit that controls the operation of the cylinder based on an instruction signal from the sequencer. In the control device, a detection unit that detects the actual speed of the cylinder; a determination unit that compares and determines the actual speed signal from the detection unit and the scheduled speed signal from the sequencer;
A cylinder speed characterized by having a drive section that outputs a difference signal as a control signal according to the speed difference determined by the determination section, and a hydraulic pressure adjustment section provided in the hydraulic circuit that operates based on the control signal. Automatic control device. (2) comprising a correction unit that corrects the scheduled speed signal from the sequencer based on a physical quantity such as a weight difference or a dimensional difference between the actuated bodies, and inputs the corrected speed signal to the determination unit as a reference speed signal of the actuated body; An automatic cylinder speed control device according to claim 1, which is characterized by:
