Abstract

In a sorter having a sheet deflector associated with each bin of the sorter, the deflectors are operated in a desired sequence to direct the sheets into different bins in turn. A magnetic control mechanism for the deflectors is employed. This comprises a bank of rotary magnetic devices 1 each comprising a bar magnet 2 pivotally mounted between pole pieces 3,4 which are themselves magnetizable, by passing current through a coil 5, to one or other polarity to rotate the bar magnet between the positions shown.

MAGNETIC DEFLECTOR CONTROL MECHANISM FOR SORTERS

(Cont'd)

FlG. 2a

In a sorter having a sheet deflector associated with each bin of the sorter, the deflectors are operated in a desired sequence to direct the sheets into different bins in turn.

A magnetic control mechanism for the deflectors is employed. This comprises a bank of rotary magnetic devices 1 each comprising a bar magnet 2 pivotally mounted between pole pieces 3,4 which are themselves magnetizable, by passing current through a coil 5, to one or other polarity to rotate the bar magnet between the positions shown.

The bar magnets are connected to respective deflectors and in one position activate the associated deflector to guide a sheet into the bin and in the other position retract the deflector.

It is noted that only a pulsed current is required to operate each device since the device is bi-stable and self-latching.

In Figure 1, the magnets 2 are shaped to engage the pole pieces. In a preferred form as shown in Figures 2 and 2a, the magnet is rectangular and the pole pieces are tapered. No adjustment is required since the pole pieces limit and define the rotary movement of the ma net. Figure 2 also shows...
