Abstract
A stacking device for sheets emerging from an ejection opening (for example, a photocopying machine), whereby the sheets are alternately distributed and stacked in several positions relatively displaced to each other. The relatively displaced stacks are formed by a one-sided engagement of the sheets to be stacked by a switchable turning mechanism controlled by a steering device.
Claims12
A stacking device for the displacement of sheets comprising:
- a feed slot for supplying free-falling sheets to the stacking device,
- an inclined storage tray for the sheets fastened behind said feed slot in the direction the sheets are moving in order to accommodate fan-like relatively displaced sheets,
- a ledge fastened between the feed slot and the storage tray beneath the free-falling sheets emerging from said slot,
- at least one anchor mounted above said ledge and arranged to one side of the middle of the sheets emerging from said slot so that the sheets pass between the ledge and the anchor on the way to the storage tray,
- at least one magnet mounted on the ledge for said anchor,
- an electrical scanning device for detecting the sheet ends emerging from said feed slot, and
- a switching means electrically connected with said scanning device and the magnet and serving to alternately energize the magnet, whereby said anchor presses the free-falling sheet onto said ledge causing rotation of said free-falling sheet about an axis passing vertically through the anchor, so that the sheet arrives at said storage tray in a position corresponding to its rotary motion.

A stacking device for the displacement of sheets comprising:
- a feed slot for supplying sheets to the stacking device,
- a storage tray for the sheets fastened behind said feed slot in the direction the sheets are moving in order to accommodate relatively displaced sheets,
- a ledge fastened between the feed slot and the storage tray beneath the sheets emerging from said slot,
- at least one anchor mounted above said ledge so that the sheets emerging from said feed slot pass between the ledge and the anchor on the way to the storage tray, and
- a control means connected with said anchor so that the anchor is adjustable left and right above the emerging sheets, whereby said anchor presses the sheet onto said ledge causing rotation of said sheet about an axis passing vertically through the anchor so that the sheet arrives at said storage tray in a position corresponding to its rotary motion.

A stacking device for the displacement of sheets comprising:
- a feed slot for supplying sheets to the stacking device,
- a storage tray for the sheets fastened behind said feed slot in the direction the sheets are moving, having a first compartment for sheets emerging straight on, a second compartment for sheets displaced to the right, and a third compartment for sheets displaced to the left,
- a ledge fastened between the feed slot and the storage tray beneath the sheets emerging from said slot,
- at least one anchor mounted above said ledge so that sheets emerging from said feed slot pass between the ledge and the anchor on the way to the storage tray, and
- a control means connected with said anchor so that the anchor is adjustable above the middle and to the right and left of the middle of the emerging sheets for selecting said compartments in said storage tray, whereby the sheets passing directly beneath said anchor move straight on to the first compartment, and the sheets passing beneath the anchor adjusted to the right and left of the sheet center pass into a selected second and third compartment of said storage tray in a position corresponding to their rotary motion which is produced by the anchor pressing the sheet onto the ledge causing rotation about an axis passing vertically through the anchor.
