Abstract

The impact bar of this collator is automatically adjusted in accordance with the size sheet being collated, so as to place the trailing edge of all sheet sizes in a common plane, at the mouth of the collator bins. As a result, sheet jamming at the collator bins is minimized.

Collator Impact Bar

The impact bar of this collator is automatically adjusted in accordance with the size sheet being collated, so as to place the trailing edge of all sheet sizes in a common plane, at the mouth of the collator bins. As a result, sheet jamming at the collator bins is minimized.

In Fig. 1 copier 10 is shown selectively supplying output copies to exit tray 11 or collator 12. The collator includes one or more movable impact bars or plates 13, movable in the direction shown by arrow 14. The copier includes at least two sheet supply trays 15 and 16. Each tray includes sensors, not shown, operable to sense the size sheets in each tray. In the alternative, the operator may manually set a sheet size dial when filling the trays, or the sheet size may be sensed as it traverses the paper path within the copier.

Fig. 2 shows the mechanism which automatically adjusts the position of impact bars 13 so as to place the trailing edge of each size sheet at a common plane 17, identified by broken line 18 in Fig. 1, as the copier's output sheets follow the sheet path generally identified as 19. It is assumed that for a given collate run, all sheets are of the same size.

Referring to Fig. 2, the bottom of bar 13 is rotatably supported in bearing 20, and is rotatably supported at its upper end, adjacent gear 21, by another bearing, not shown. Gear 21 meshes with gear 22. This gear rotates with shaft 23, which shaft is rotatably supported by bearings, not shown.
