ABSTRACT:
An apparatus for feeding, selecting and sorting has a coding and feeding unit, a sorting machine and a synchronizing unit. The coding and feeding unit has a keyboard for keying in codes of respective unloading-station destinations of respective items thereat and conveys the items from the keyboard. The sorting machine has a monorail of T-shaped cross section, a plurality of conveying devices for conveying respective items in one direction along the monorail, a chain for moving the conveying devices along the monorail in the one direction one after the other, and pairs of feed rods spacedly parallel to each other, the pairs of feed rods being spaced along the monorail for defining an unloading station at each pair of the feed rods therealong and spaced from the monorail for sliding contact with slidable contacts of each conveying device as it moves therepast along the monorail in the one direction. Each conveying device has at least two pairs of idle wheels with substantially horizontal axes supporting the conveying device on the monorail for movement in the one direction therealong, at least one pair of idle wheels with substantially vertical axes for guiding the conveying device along the monorail in the one direction, a pair of rollers and a rotary belt thereabout for receiving the respective item of the conveying device and unloading the item by rotary movement of the belt transverse to the one direction, a permanent magnet D.C. electric motor for rotating the rotary belt, and the pair of slidable contacts connected to the motor. The synchronizing unit successively receives the items from the coding and feeding unit and feeds them respectively to the conveying devices. For this, the synchronizing unit has three rotating belts positioned one after the other, the speed of the rotation of the three rotating belts being controllable independently of one another.
