Envelope Picker Separator

For reliable sheet or envelope picking various techniques such as reverse buckling, lifting and dropping the picker to break the interstack friction and control of the height of the stack to close tolerances have been employed.

Illustrated is a device which accomplishes reliable picking without employing any of the three mentioned techniques. This picker is activated by the picking of a magnet that engages a clutch, not shown, which causes rotation of the shaft, Fig. 1, in the clockwise direction by belt 2. When the magnet picks it also pulls downward on link 3. This rotates clutch release mechanism 4. The left arm of clutch release mechanism 4 is slightly longer than the right arm, as shown in Fig.
2. Prior to the picking of the magnet, the step on the Latch release ring 5 of clutch 6 is resting on position "a" as shown in Fig. 2.

As the clutch release mechanism 4 rotates clockwise, as shown in Fig. 1, the right top corner of the longer left arm is deflected leftward and latch release ring 5 flies through slot "b" engaging the clutch. After making one revolution, the step on clutch release ring 5 stops on position "c" on top of the left arm of clutch release mechanism 4, disengaging the clutch. When the magnet drops, extension spring 7 rotates clutch release mechanism 4 counterclockwise to its original position. When this happens, the step on clutch release ring 5 falls from position "c" Fig. 2, to a position "a", ready for the next cycle.

It should be noted that each time the magnet picks, clutch 6 and its affixed components make one revolution and stop, but shaft 1 and its affixed components continue to rotate until the magnet drops.

Clutch 6 is affixed to one end of spindle 8 while pulley 9 is affixed to the other end. High-friction drive roller 10 is affixed to shaft 1. Pivot arm 11 is free to rotate on shaft 1. At the end of pivot arm 11 is affixed grooved pulley 12, which does not rotate, but over which high-friction belt 13 slides when pulley 9 is rotating. High...
