Abstract
In a guide track (1) there travel a plurality of carts (2) which are driven by an endless chain (8). Each cart (2) carries a load bearing tray (3), which is intended to receive a package or the like. At predetermined discharge locations the load bearing trays are tilted into an inclined position so that the packages slide into a collecting container. To the load bearing tray there is attached a shaft (12) which extends diagonally to the load bearing tray surface, and which is journalled rotatably in a bearing (11). To tilt the load bearing tray (3) the shaft (12) is tilted by a drive disc (15) which is connected to the shaft (12) through a shaft (14) and a universal joint (13). The drive disc (15) itself is braked by means of electromechanical or mechanical guide rails at predetermined discharge locations upon passage of the cart and is thereby rotated. The apparatus for tilting the load bearing trays is very simple and functions largely trouble free.
