Abstract
Each of sorting mechanisms on a sorter drum comprises a substantially trapezoidal slit defined in a cylindrical wall of the sorter drum and providing a substantially trapezoidal tongue displaced radially outwardly from the cylinderical wall, and a substantially trapezoidal guide body having a holder plate held against the trapezoidal tongue and a pair of slide webs bent from and extending along opposite side edges of the holder plate and fitted in the slit, the holder plate and the slide webs having edges projecting radially outwardly from the cylindrical wall and defining an opening in the cylindrical wall. A detector for detecting pieces sorted out is mounted on each collector guide extending around the sorter drum. An electric control circuit is responsive to a signal from the detector for automatically stopping a motor which rotates the sorter drum. The control circuit is also responsive to signals from detectors which detect pieces of different sizes for automatically stopping rotation in one direction of the motor and then, with a time delay, for automatically starting rotation in the opposite direction of the motor, so that the pieces of different sizes can automatically be …
