Pivoted belt clamp to align with belt twist during linear motion in print job finisher

摘要

A sheet stack aligning mechanism for a print job finishing machine is provided. The mechanism includes a belt driven in a reciprocating motion; a stationary rod having a longitudinal direction; a sheet stack alignment tamper that tamps a stack of sheets into alignment; and a belt clamp. The belt clamp has a main body attached to the sheet stack alignment tamper, a pivot pin, a belt attachment portion pivotably attached to the main body by the pivot pin, the belt attachment portion being fixed to the belt such that it does not move relative to the belt, and a bushing portion fixed to the main body and slidably attached to the rod. The pivot pin permits the belt attachment portion to follow a movement of the belt in a direction non-parallel to the longitudinal direction while the main body moves only in the longitudinal direction of the rod.

主权项

1. A sheet stack aligning mechanism for a print job finishing machine, the mechanism comprising:
a first belt driven in a reciprocating motion in a first direction and a second direction opposite to the first direction; a first stationary rod having a longitudinal direction and configured to be stationary relative to a body of the print job finishing machine; a first sheet stack alignment tamper that is configured to tamp a stack of sheets of media into alignment; and a first belt clamp having
a first main body attached to the first sheet stack alignment tamper,a first pivot pin,a first belt attachment portion pivotably attached to the first main body by the first pivot pin, the first belt attachment portion being fixed to the first belt such that the first belt attachment portion does not move relative to the first belt, anda first bushing portion fixed to the first main body and slidably attached to the stationary rod, wherein the first pivot pin permits the first belt attachment portion to follow a movement of the first belt in a direction non-parallel to the longitudinal direction of the stationary rod while the first main body of the first belt clamp moves only in the longitudinal direction of the stationary rod.
