Title: Controller for arm shift driving motor
Inventor: HOSHI HIROTOSHI
IPC: B25J9/16
Filed: 1987-02-20
Abstract: PURPOSE:To simplify an operation to automatically reset a chuck to its track by calculating the position coordinates of the chuck and outputting a necessary pulse by a controller with the signal outputted from a detecting circuit when the chuck gets out of its track during its movement. CONSTITUTION:When a chuck is moved, a controller 8 reads the pulse data out of a memory R1 to give them to pulse motors M1 and M2. Thus both motors revolve at angles corresponding to said pulse data and the chuck moves along a prescribed track. If the chuck gets out of its track and a magazine hits a chamber, a detecting circuit 9 outputs a signal. This signal is received by the controller 8 and the controller 8 calculates the position coordinates of the chuck from the detection values of encoders E1 and E2 as well as the absolute coordinate value of a memory R2. Then the controller 8 applies a pulse to the motor M1 so that the chuck is reset to its track. Thus it is possible to simplify an operation to automatically reset the chuck to its prescribed track.
