Abstract

A stapling system for accommodating variable numbers of copy sheets from a copying machine utilizes a fixed stapling head 1 mounted in an inverted position on a support frame 2 and a movable or active clinch and clamp devices- This approach can improve alignment between the clamp and the head, allows a linear motion for the clamp (rather than the arc motion implied in a movable head) and allows paper sets to be referenced to the fixed headS

ELECTROMECHANICAL STAPLE DRIVING MEANS (Cont~d)

A stapling system for accommodating variable numbers of copy sheets from a copying machine utilizes a fixed stapling head 1 mounted in an inverted position on a support frame 2 and a movable or active clinch and clamp devices~ This approach can improve alignment between the clamp and the head, allows a linear motion for the clamp (rather than the arc motion implied in a movable head) and allows paper sets to be referenced to the fixed headS

Upward activation of the plunger 3 for the stapling head for driving a staple through a set of copy sheets 4 is accomplished by a first cam 5 eccentrically mounted for rotation on a drive shaft 6~ As shown in the drawing, the cam 5 is at its lowermost position, and when rotated to its upper position, drives the plunger 3 upwardly by way of a cam follower 7 mounted at the lower end of the plunger~ This action drives a staple through the set of copy sheets~ Immediately prior to this

action, the rotating shaft 6 rotates a second cam 8 which produces movement of a link 9 by way of a cooperating cam follower 1O~ The link in turn rotates crank 11 to drive a stapling clamp member 12 downwardly onto the top side of the copy set 4~ The linkages are such that the c...
