Title: Method for controlling pressure pin in pressure casting machine and device therefor
Inventor: IWAMOTO NORIHIRO
IPC: B29C45/80
Filed: 1994-10-26
Abstract: PURPOSE: To improve the quality of a cast product by automatically controlling a stroke of a pressure pin so as to optimize to the prevention of development of shrinkage casity. CONSTITUTION: The stroke S in no load condition of a pressure pin cylinder 12 for driving the pressure pin 10 is measured. A value (S-α) substracting a prescribed minite quantity α from the stroke S of the pressure pin 10 is set as the stroke of the pressure pin, and after the lapse of a prescribed waiting time from the starting of fill-up of molten metal into a cavity, the pressure pin 10 is advanced. Then, the actual stroke Sf of the pressure pin 10 is measured and the stroke detected value Sf of the pressure pin and the preset stroke value (Sα) are compared.  At least one parameter among the pressure, the flow rate of pressure oil for supplying into the pressure pin cylinder and the waiting time from the completion of fill-up of the molten metal to the advance of the pressure pin, is corrected so that the stroke of the pressure pin becomes the preset stroke (S-α).

Title: Direct teaching type robot controller
Inventor: TAKEMOTO AKINOBU
IPC: G05B19/42
Filed: 1989-10-11
Abstract: PURPOSE:To attain a direct teaching operation with a light force and with high accuracy without slipping down a vertical axis by outputting fixedly the value which detected a motor current command in a position servo state and detecting the motor current command as a command produced in the position servo state to switch the command which is fixedly outputted. CONSTITUTION:In a direct teaching state, the motor current command of a vertical axis 27 is switched to a sample and hold circuit output command from a command produced in a position servo state with continuous pushing actions of a direct teaching switch 20 provided to a teaching box 19. At the same time, a horizontal axis functions to cut the motor power supply and stops the transmission of a current command. Therefore the axis 27 is driven by a fixed command equivalent to the force applied in the gravity direction, and an operator can freely teach the position of the axis 27. Thus the axis 27 is held at the relevant position even though the operator releases his/her hand from an action axis. When the switch 20 is released, all axes are switched again to a position servo system at the relevant position and held there. In such a constitution, the axis 27 never slips down and a safe and highly precise direct teaching operation is attained with a robot controller.
