  • Patent number: 8015778
    Abstract: In a method for filling bulk goods into containers designed to accommodate a certain number of bulk items, at least one bulk goods conveyor is used to transport the bulk goods towards at least two pickers which are consecutively arranged in the direction of transport. The pickers are used to fill the bulk goods into empty spaces in containers, transported on at least one container conveyor. When the supply of bulk goods decreases or is discontinued, the at least one picker arranged downstream in the direction of transport of the bulk goods conveyor gives preference to containers with a high filling level. Completely empty containers are preferably no longer filled. Thus the bulk goods conveyor can be emptied within a short period and almost all bulk goods are packed without necessitating manual filling of the containers.

  • Patent number: 6097992
    Abstract: A method for avoiding scratching of wafer backs being held by a vacuum to a fetch arm of a stepper machine for insertion into a cassette holder includes releasing the vacuum in the suction head of the fetch are before the wafer enters the cassette holder. The release of vacuum reduces frictional force between the wafer back and the suction head when the wafer accidentally hits the side of the cassette holder. Therefore, the vacuum release method avoids scratching of wafer backs by the suction head of the fetch arm. The invention requires a separate vacuum release controller to release the vacuum in the suction head for a prescribed delaying period after the fetch arm starts moving toward the cassette holder.

  • Patent number: 5395206
    Abstract: A system for filling orders in a warehouse utilizes a main conveyor for routing items in the warehouse, including to a primary and secondary picking area. The primary picking area is used for picking high volume items, and is subdivided into multiple subgroups of primary pick faces. The second picking area is used for picking items that are not available for picking in the first picking area. Picking is performed in alternating short pick periods. Picking from a first subgroup of primary pick faces is performed in a first pick period, and picking from the second subgroup of primary pick faces is performed in an alternating pick period. Items are assigned to the first picking area dynamically for each picking period on the basis of which items are the highest moving items during an individual pick period. The system utilizes a pivotally mounted diverting chute to direct items into the pick faces, etc., and a self opening pick face.

    Abstract: The installation comprises a delivery conveyor (4) for delivering unit items in buckets (5). A station (3) injects unit items onto the delivery conveyor. A sorting conveyor (6) carries packs (8) corresponding to respective batches to be made up. The sorting conveyor is disposed relative to the delivery conveyor so as to establish at least one item transfer zone therebetween. A central control unit (10) ensure that desired coincidences occur between item-containing buckets (5) and packs (8) for receiving the items, with the control units controlling the transfer of items form the buckets to the packs. The invention is particularly applicable to making up batches of items in response to orders therefor.
