Sheet Separator Feeder

There is shown and described a device for reliably separating and feeding cut sheets which obtains the action of two drive devices without requiring extra hardware.

Fig. 1 is a top view of the device. Shaft 2 is mounted for free rotation in yoke
4. A drive pulley 6 is mounted on shaft 2. Endless belt 8 is drivingly connected to driven pulley 10 which is fixedly mounted on shaft 12, as is the friction wheel feeder 14. Endless belt 8 is also trained around driven pulley 16 fixedly mounted on shaft 18. Shingler separator wheel 20 is also fixedly attached to shaft 18.

Refer to Fig. 2. In operation, when drive shaft 2 is rotated counterclockwise by a motor (not shown), a torque is produced in the system about the center shaft 2. Shingler wheel 20 moves into contact with stack 30; at the same time, friction feeder wheel 14 moves away from the stack 30. Continued rotation of drive pulley 6 in direction 34 causes separator wheel 20 to shingle the topmost sheet out in direction 31 from restraint finger 32. The topmost sheet is then ready to be fed into the document path (not shown) in the direction of arrow 35.

Reversing the direction of rotation of drive shaft 2 to counterclockwise causes tension in belt 8 in the direction designated 36. This produces a reverse torque about the center shaft 2 and moves separator wheel 20 away from stack 30. At the same time, friction feed wheel 14 is moved into contact with the stack for driving the topmost documen...
