Abstract

This friction-type document separator provides increased belt life and wear compensation along with simplified belt changing and large separation for easy jam removal. Separator belt 1 moves in a clockwise direction around the rotating drums. Restraint belt 2 moves in a counterclockwise direction in the area where the two belts are in proximity. Tension is maintained in belt 2 by tension arm 4 and associated tension spring 5. Throat arm 3 is pivoted for rotation about pivot point 3A so that it causes belt 2 to have a self-energizing bias toward belt 1 and yet forms a movable throat for documents 8 to enter. Fanning action and a one-by-one feeding of documents 8 is thus provided.

Self Adjusting Restraint Belt for a Friction Separator

This friction-type document separator provides increased belt life and wear compensation along with simplified belt changing and large separation for easy jam removal. Separator belt 1 moves in a clockwise direction around the rotating drums. Restraint belt 2 moves in a counterclockwise direction in the area where the two belts are in proximity. Tension is maintained in belt 2 by tension arm 4 and associated tension spring 5. Throat arm 3 is pivoted for rotation about pivot point 3A so that it causes belt 2 to have a self-energizing bias toward belt 1 and yet forms a movable throat for documents 8 to enter. Fanning action and a one- by-one feeding of documents 8 is thus provided.

Lower restraint belt idler pulley 7 next to the separator drum is also carried on arm 3. The pivot geometry is such that even with documents 8 jammed between the separator and restraint belts, arm 3 can be moved upward and out of the way by grasping handle 9 and rotating the assembly to the position shown by the dot- dash lines. The force required to operate arm 3 is only moderate. When in its upper position, restraint belt 2 completely clears the separator drum and belt 1 so that jammed documents can readily be removed.

When arm 3 is restored to its normal operating position as shown, arm 3 is forced downward by friction between belts 1 and 2 to thus cause it to assume its normal condition for feeding of documents.
