20110222972 | SEGMENTED CONVEYOR AND AIR FILM CHUTE - A package sorting system. The package sorting conveyor system includes a conveying track, at least one unloading station and an air-film lubricated entrance chute upstream of the unloading station to receive the package. In one embodiment, the entrance chute includes a plenum including a plurality of spaced apart apertures and an opening for communicating with an air supply; and a segmented conveying surface in communication with the apertures, wherein the segmented conveying surface includes at least one air-film lubricated bottom surface and at least one air-film lubricated side wall substantially perpendicular to the at least one bottom surface. In one embodiment, the apparatus further includes a positioner assembly for selectively positioning the outlet of the entrance chute. | 09-15-2011 |
20130341157 | INDEPENDENT DISCHARGE SORTING CONVEYOR - A sorting conveyor for transporting objects and unloading objects at one or more unloading stations adjacent the conveyor. The sorting conveyor includes a conveyor track and a train of conveyor carts connected end-to-end. At least one of the conveyor carts may include a frame base for engaging the conveyer track; a carrying tray for holding the objects; and a support for supporting the carrying tray above the frame base. A tilting mechanism including at least one gear having at least one cam is adapted for tilting the carrying tray toward at least one side of the conveyor. The present inventions may further include a tilt sensor for determining the direction of tilt of the tray. In addition, a drive motor and a driven member attached to the frame base may be included for moving the conveyor carts around the track. | 12-26-2013 |
