Multiple Bin Sheet Feed Apparatus Utilizing a Single Feed Clutch

A multiple bin sheet feed apparatus utilizes a single sheet feed clutch to effect sheet delivery from each of the sheet bins.

Sheets are forwarded from a selected one of the sheet bins 11, 13, 15 upon the energization of clutch C1. Energization of this clutch effects the simultaneous rotation of picker wheels 16, 17 and 18, and the simultaneous rotation of the separator rolls 19, 20, 21 and the retard rolls 22 and 23. A sheet is forwarded from the selected bin by the action of the picker roll and the corresponding separator roll, to its associated continuously running drive roll 24, 25, 26 and thence to a sheet utilization device. Clutch C1 may be energized earlier in the cycle when feeding sheets from bin 15, then when feeding sheets from bin 11, in order to compensate for the different distances travelled by sheets forwarded from their respective bins.

Clutchs C2, C3 and C4 control bin selection. Energization of clutch C4 causes picker wheel 16 to be lowered onto the sheets in bin 11 and causes retard roll 22 to close, to form a nip with separator roll 19 and further effects the closure of drive rolls 24. Since only one clutch C2, C3, C4 is energized during a sheet feed cycle, the remaining picker wheels 17 and 18 are raised above the sheet stack and the remaining rolls are opened so that sheets will not advance therebetween.
