SHREDDER AUTO FEED SYSTEM

摘要

A shredder has cutter elements for destroying articles (paper) and a feed mechanism for advancing paper from a stack in a tray into cutters for shredding. The feed mechanism has a feed member provided adjacent to the tray with an elastic arm for engaging and disengaging the stack. The feed member rotates in a feeding direction about an axle, with the elastic arm elastically deforming to apply pressure to feed paper atop the stack to the cutters. The elastic arm can include a protruding tip that is inserted into the stack. The tray includes a curved feed bed to assist in feeding paper into the cutters and deforming the elastic arm. A pivot arm can also move the feed member relative to the tray (e.g., vertically). A disengagement mechanism can hold the feed mechanism in an inoperable feeding position when a drawer or tray is moved into an open position.

主权项

1. A shredder comprising:
a housing; a paper shredder mechanism received in the housing and including a motor and cutter elements, the motor rotating the cutter elements in an interleaving relationship for shredding paper sheets fed therein; a tray for holding a stack of paper sheets to be fed into the cutter elements; a movable feed mechanism positioned above the tray, the movable feed mechanism comprising at least one feed member with at least one elastic arm, the at least one feed member adjacent to the tray for engaging and disengaging the stack with the at least one elastic arm; and a feed driver system constructed to drive the at least one feed member to rotate in a feeding direction with the at least one elastic arm thereof elastically deforming to apply pressure to feed paper sheets atop the stack to the cutter elements.
