COVER RIBBING POSITION REGULATING MECHANISM FOR BOOKBINDING APPARATUS
Document Type and Number:
Japanese Patent JP3889654
PROBLEM TO BE SOLVED: To provide a cover ribbing position regulating mechanism for a bookbinding apparatus which can automatically regulate a ribbing position of a cover with a simple mechanism.
SOLUTION: When a distal end of the cover 17 approaches a cover ribbing position in which ribbing rollers 41, 43 and ribbing rollers 43, 44 are oppositely disposed, a drive shaft 48 rises in a direction of an arrow while rotating. The cover 1 is interposed between recesses 5 of the rollers 41, 43 and ridging shapes of the rollers 42, 44, and hence the cover 17 is linearly ribbed while being fed. If the ribbing position is regulated, when a drive motor 57 is rotated by a set quantity, a feed screw 55 is rotated, a moving block 53 is laterally moved along a guide 56 according to a rotating direction of the motor 57, and the roller 41 is moved to a set position via a baring 54 in association with the lateral movement. Then, paired ribbing rollers 2 are moved to a position set in association with the movement of the roller 41 by engaging the recesses 50 with the protrusion 51 of the ribbing part of the paired rollers 41.
