| 摘要 | The present application discloses a method and apparatus for conveying parcels on a plurality of transport units (32) moving in a conveying path (30) between an induction station (26) and a discharge station (28). Each transport unit has a driven carrier belt (36) thereon, which is moveable orthogonally to the conveying path. The induction station includes a plurality of tandem driven induction belts (62), extending at an angle to the conveying path. The.discharge station has a plurality of receiving ports (46) positioned along the conveying path. The invention provides a crossbelt sortation system (25) with a transport unit test station (96) that is positioned adjacent to the conveying path. The purpose of the test station is to test movement of the carrier belt associated with individual ones of the transport units passing the test station. Each of the transport units (32) includes a magnet (204a, 204b) that moves in proportion to the linear speed of the carrier belt (36) associated with that transport unit. The test station includes a sensor (200) that senses the magnet of a transport unit passing the test station (96). The sensor includes at least one Hall-effect cell (208a, 208b) and a magnetic antenna (210) coupled with the Hall-effect cell. | ||||||
