CYLINDER OF FIXED CAPACITY, APPARATUS FOR LIFTING CONTAINER BEING FILLED WITH LIQUID BY ABOVE CYLINDER AND APPARATUS FOR CONTROLLING RECIPROCALLY LINEARLY OR INTERMITTENTLY MOVING DEVICE SUCH AS DEVICE FOR INTERMITTENTLY CARRYING CONTENT
PURPOSE:To enable a stroke or a speed characteristic curve to be changed, by controlling the speed of a servo motor in terms of a stroke amount, a stroke time and the speed data for the speed characteristic curve and terminating the operation of the servo motor when the stroke amount reaches a preset value. CONSTITUTION:A piston 24 of a fixed capacity cylinder 23 is to be displaced by a stroke length in accordance with predetermined filling time and quantity at a speed commensurating with a speed characteristic curve expressed by the speed data stored in a speed function memory ROM 54. When the piston 24 moves as much as the stroke length corresponding to the predetermined filling quantity, a preset counter 58 counts up and the count-up signal is sent to CPU 60, whereby an operation stoppage signal is sent from the CPU 60 to a pulse generating circuit 51 to stop the operation of the pulse generating circuit 51 for stopping the operation of a servo motor 29. Also, the filling time and quantity can be changed by changing the preset values of a filling time setting device 63 and a filling quantity setting device 64.
