  • Patent number: 7398885
    Abstract: An apparatus for selective diversion of objects such as containers, packing and packing units of different mass. The apparatus has a first transport device for the objects and a diversion device for diverting predetermined objects from the first transport device onto a second transport device. The intensity with which the objects are diverted from the first transport device onto the second transport device is controlled by means of a controlled device.
    Type: Grant

  • Patent number: 7232026
    Abstract: The apparatus serves to distribute a random stream of items into several lanes in which the items are transported individually one after the other. The apparatus has a transport device for the items, wherein the transport device has one or more driven conveyor belts and side rails as well as a lane divider. The lane divider has at least one movable divider which divides the stream of transported items. A middle divider can project against the direction of transport and side dividers can be set back staggered. In an embodiment, the lane divider has a frame to which the dividers are attached. The apparatus also has a device for driving the lane divider, so that the at least one divider carries out a back-and-forth movement in the direction of transport and/or transversely to it.

  • Patent number: 6588575
    Abstract: The device (20) for diverting individual items from a stream of items which are conveyed on a transport apparatus has an extendable and retractable diversion element (22), which is operated via a gear unit (26, 28, 30, 32, 34) by a drive apparatus moving or swinging to and fro and is precisely time-controllable, in order to impart a cross impulse to items to be diverted so that they slide from the transport apparatus (11) across the direction of transport. The diversion element (22) carries out a complete extension and retraction movement during a single to-or-fro movement or swing of the drive apparatus. The drive apparatus moving to and fro can be a pneumatic cylinder (42), and the gear unit which transmits the piston movement to the diversion element (22) can be a coulisse link mechanism (26, 28, 30, 32, 34) or a toggle lever.
