Appl. No.:

12/861553

Inventors:

Matthew A. Steenwyk - Grandville MI, US

Thomas H. Triesenberg - Rockford MI, US

Assignee:

Dematic Corp. - Grand Rapids MI

International Classification:

B65G 47/46

US Classification:

19837002

Abstract:

A positive displacement sorter and method of diverting articles includes providing a plurality of interconnected parallel slats defining an endless web that travels in a longitudinal direction, an upper surface of which defines an article-conveying surface and a plurality of pusher shoes. Each of the shoes travels along at least one of the slats in order to laterally divert articles on the conveying surface. Each of the shoes has a diverting member extending below the conveying surface. A plurality of diverting rails below the conveying surface are each capable of engaging the diverting member to cause the associated shoe to travel laterally to divert an article. A plurality of diverters are provided for selectively diverting at least one of the diverting members from a non-diverting path extending longitudinally along the sorter to one of said diverting rails in a diverting state. At least one of the diverters has a gate having a diverting surface. The gate is selectively moveable between the diverting state and a non-diverting state.

Abstract:

A goods-to-person picking station and method of picking goods from a product container and placing the goods in at least one order container includes a product container-handling mechanism and at least one order container-handling mechanism juxtaposed with the product container-handling mechanism. The product container-handling mechanism supplies a product container to a pick area. The at least one order container-handling mechanism supplies at least one order container to the pick area. In this manner, an operator can pick goods from a product container at the pick area and place the goods selectively to the at least one order container at the pick area. The product container-handling mechanism includes a product container elevator assembly and a product container extractor assembly. The elevator assembly elevates a product container from the feed area to the pick area. The extractor assembly transfers a product container from the pick area. The elevator assembly and the extractor assembly may be operated from a common drive assembly.

International Classification:

G06F 11/00

US Classification:

702183, 198571, 7311801, 738659, 738664

Abstract:

A technique is provided for diagnosing deficiencies in a material handling system having a track and a material support member adapted to travel on the track. A diagnostic device travels with the material support member and includes one or more sensors that measure one or more parameters of the material support member. Such parameters may include an amount of force exerted laterally against one or more restraining members or the accelerations of the material support member. The material handling system may include a plurality of slats connected in an endless web that defines a conveying surface upon which articles are transported.

B65G 39/16
B65G 23/44
B65G 47/66
B65G 21/10

Abstract:

A conveyor employs an infeed assembly and outfeed assembly, each comprising a nosebar assembly that may be mounted to a conveyor frame to transition a conveyor belt between a returnway and a carryway. The outfeed assembly further includes a drive sprocket and a limiter to ensure engagement of drive elements on the conveyor belt with the drive sprockets. A limiter plate ensures proper placement of the limiter relative to the drive sprocket. The infeed assembly and outfeed assembly components may be easily mounted to and removed from the conveyor frame to facilitate replacement, cleaning or maintenance.
