Title:
PUNCHING SYSTEM, CONTROL METHOD THEREOF, SHEET PROCESSING DEVICE AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2017154191
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a punching system and a control system that shorten a start-up time to the minimum and improve productivity.SOLUTION: A punching device C comprises: a plurality of punching members 40; a drive motor 42 that drives the punching members; a rotation driving shaft 43 that transfers rotations of the drive motor to the punching members; and a control part 87 that controls the drive motor. The rotation driving shaft, during one rotation, has first and second operation positions where at least one punching member performs punching operation and first and second home positions where all the punching members are in a stand-by state, alternately. The control part determines a rotation position of the rotation driving shaft by detecting edges of first and second sensor flag members 77 and 78 fixed to the rotation driving shaft with use of first and second position sensors 75 and 76.SELECTED DRAWING: Figure 9
