Sheet jogger

Abstract

A sheet jogger to justify and align a stack of sheets into a registered bundle which is subsequently discharged into a bin. Prior to discharging of the bundle, the stack of sheets can be stapled. Each bundle is offset from every other bundle when discharged into the bin. Sheets are fed onto a jogging deck by at least one conveyor roller to abut against at least one gate finger at the end of the jogging deck. A back jogger aligns the sheets into registration against the gate finger and a left side jogger assembly jogs the sheets into alignment against a right side jogger assembly. The gate fingers drop down and a lower eject roller rises above the jogging deck to engage a bottom sheet of the stack thereby engaging the stack against an upper fixed pressure roller. On the next jogging operation, the initial jogging operation is repeated and the left side guide assembly and right side guide assembly return to a rest position prior to ejection of the aligned bundle thereby offsetting the ejected bundle a distance equal to travel of the front side guide assembly. All mechanical jogging operations are controlled by a cylindrical control means having an axial curved circular detented jogger cam supported on a radial detented hub mounted below the jogging deck. A stapler and corresponding anvil mounted on the jogging deck can staple each aligned justified bundle of sheets together.
