Stack Deflector

A flexible band is arranged in a document stacker to produce a moving deformation to deflect previously stacked documents from the path of an incoming document.

An incoming document 1 enters the stacker along guide 2 and slides on vane 3a of vane wheel 4. Leading edge 5 strikes band 6 which has ends 7 and 9 secured to shield 8. The band is of thin, flexible material such as MYLAR* or steel shim stock and bows outwardly from shield 8 toward documents 11 stacked on plate 12.

As document 1 engages the band, a wave 13 is created in the band forcing the stacked documents away from leading edge 5.

The wave moves with the leading edge until reaching secured end 7. Document 1 continues until arrested by stop 14. The band is effective in deflecting stacked documents of variable length having deformations or mutilations on their edges which would otherwise interfere with the incoming document.

When the next document is selected for the stacker, vane wheel 4 is first incremented 90 degrees clockwise by mechanism, not shown, thus lowering document 1 onto plate 12 with stacked documents 11. Plate 12 is pivoted on stud 15 and has a back plate 16 on it.

Rotation of vane wheel 4 also positions vane 3b to receive the next document. *Trademark of E. I. du Pont de Nemours & Co.
