Abstract

The mechanism shown provides a means of separating the separator restraint roll combination of a paper roller picker separator mechanism for improved paper clearance capability, but still maintains the precise interference adjustment accomplished through a roll interference adjustment mechanism when the rolls are returned back into contact.

Roll Separation Mechanism

The mechanism shown provides a means of separating the separator restraint roll combination of a paper roller picker separator mechanism for improved paper clearance capability, but still maintains the precise interference adjustment accomplished through a roll interference adjustment mechanism when the rolls are returned back into contact.

The compensator 1 fits over the restraint shaft 2. The worm 3 mates with a helical gear section projecting from the compensator 1. As the worm 3 is rotated it rotates the compensator 1 about the restraint shaft 2. Since the axis of the hole in the compensator 1 is eccentric to the main axis of the compensator, this rotation of the compensator raises and lowers its main axis. The axis of the restraint roll 5, which rotates in the O.D. of the compensator 1, is coincident with the main axis of the compensator, therefore it also is raised and lowered allowing an easy, precise adjustment of the roll-to-roll interference between the separator and restraint roll 5.

A wave washer is sandwiched between the face of the worm 3 and one of the housing 12 projections. This provides the locking effect necessary to prevent the worm 3 from rotating between adjustments, but is easily overcome when adjusting so as not to require loosening or tightening of a special lock before and after adjustment.

The swash plate 6 is used to drive the restraint roll 5 and also control the end play of the compensator 1. The pin 7 in the restraint roll hub fits into the slot in the swash plate 6, and due to the eccentric relation of the two parts, the pin 7 rides up and down in the slot.

The swash plate 6 is secured to the shaft 2 by a one-way overrunning clutch
8. This allows the restraint roll 5 to be driven counterclockwise.

The separation cradle 4 is free to pivot about the restraint shaft 2. The separation cradle 4 is actually positioned between the face of the main housing 12 and the...
