Abstract

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.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 161 words
Sorting conveyor for individual objects having a plurality of carts circulating along an endless track, each cart carrying a load bearing tray for the conveyed objects, said tray being tiltable from the horizontal position in both directions into an inclined position at predetermined discharge locations by guidance means arranged along the track, said conveyor being characterized in that each said load bearing tray is supported from below by a support shaft which extends diagonally to the load bearing tray surface, said support shaft being rotatably journalled within a bearing fixedly attached to said cart, in that a drive disc mounted on a vertical shaft is rotatably journalled upon the cart, said vertical shaft being in drive connection with said support shaft of the load bearing tray by means of a universal joint, and in that said guidance means at said discharge locations are so constructed as to be capable of rotating said drive disc, thereby to tilt said load bearing tray.
Claim 2
Dependent Claim 161 words
Sorting conveyor for individual objects having a plurality of carts circulating along an endless track, each cart carrying a load bearing tray for the conveyed objects, said tray being tiltable from the horizontal position in both directions into an inclined position at predetermined discharge locations by guidance means arranged along the track, said conveyor being characterized in that each said load bearing tray is supported from below by a support shaft which extends diagonally to the load bearing tray surface, said support shaft being rotatably journalled within a bearing fixedly attached to said cart, in that a drive disc mounted on a vertical shaft is rotatably journalled upon the cart, said vertical shaft being in drive connection with said support shaft of the load bearing tray by means of a universal joint, and in that said guidance means at said discharge locations are so constructed as to be capable of rotating said drive disc, thereby to tilt said load bearing tray.
Claim 3
Dependent Claim 50 words
Sorting conveyor according to claim 1, characterized in that said guidance means comprise guide rails positioned along the conveyor track, said guide rails being so constructed as to be able to electromechanically or magnetically brake the drive disc upon passage of the cart on which the drive disc is mounted.
