Belt Driven Roller Conveyor

View page
US Patent:
6390286, May 21, 2002
Filed:
Nov 3, 1999
Appl. No.:
09/433325
Inventors:
Thanh V. Nguyen - Wyoming MI
Dennis J. Schuitema - Ada MI
Assignee:
Rapistan Systems Advertising Corp. - Grand Rapids MI
International Classification:
B65G 1306
US Classification:
19878108, 19878103
Abstract:
A roller conveyor belt driver system for a roller conveyor includes a closed loop belt having a continuous driving surface and a non-circular base and a plurality of pulleys which support and engage said non-circular base for at least partially laterally restraining the belt from rotation. A first group of pulleys are constructed and arranged to position the belt in non-orthogonal orientation with respect to the rollers of the conveyor for contacting one or more rollers with the driving surface of the belt. Optionally, the belt driver system includes a lateral restraint associated with a respective pulley of the first group of pulleys to urge the belt to remain engaged with the respective pulley to prevent twisting of the belt and, therefore, increase the life of the belt. For example, the lateral restraint may comprise a bearing which is positioned adjacent the respective pulley and which contacts the belt to maintain the belt in proper orientation in the pulley. In one form, the belt comprises a link belt, which is formed from a plurality of interlocking links, which permits the belt to be easily removed for service or replacement.

Article Separation Conveyor

US Patent:
6609607, Aug 26, 2003
Filed:
Apr 20, 2001
Appl. No.:
09/838964
Inventors:
Bernard H. Woltjer - Jenison MI
Douglas E. Olson - Grand Rapids MI
John Stafford - Grandville MI
Gerald A. Brouwer - Grandville MI
Ricardo N. Schiesser - Rockford MI
Dennis J. Schuitema - Ada MI
Assignee:
Rapistan Systems Advertising Corp. - Grand Rapids MI
International Classification:
B65G 4726
US Classification:
19845703, 19845705, 198607
Abstract:
An article separation conveyor system includes a plurality of conveyors which are independently and/or collectively operable to destack, separate and/or align articles being conveyed along the article separation conveyor. The conveyor system includes a destacking conveyor, a side by side eliminating conveyor and/or an aligning conveyor. The destacking conveyor includes a plurality of conveying portions, which are inclined to convey articles up and then drop or guide them onto the next adjacent conveyor. The side-by-side eliminating conveyor includes a pair of diverting members and is operable to redirect articles from one side of the conveyor to the other to destack and separate articles as they are continuously conveyed along the conveyor. The aligning conveyor is operable to align articles along one side of the discharge conveyor so the articles are arranged for identification at a downstream scanning device and induction onto a sortation system.

Compact Article Unscrambler

View page
US Patent:
6622847, Sep 23, 2003
Filed:
Aug 3, 2001
Appl. No.:
09/921720
Inventors:
Dennis J. Schuitema - Ada MI
Ronald J. DeVree - Hudsonville MI
Curtis E. LeMay - Shelbyville MI
Assignee:
Rapistan Systems Advertising Corp. - Grand Rapids MI
International Classification:
B65G 4724
US Classification:
198399, 19837009, 1983701
Abstract:
A compact article singulation and accumulation conveyor includes a receiving portion which receives articles in random order including clusters of side-by-side articles and a discharge portion from which articles are discharged in a single file singulated stream. A first conveying surface transports articles longitudinally from the receiving portion to the discharge portion. A recirculating bed removes side-by-side articles from a downstream portion of the first conveying surface to an upstream portion of the first conveying surface. The recirculating bed is made up of at least one peel-away conveyor having a second conveying surface adapted to move side-by-side articles laterally off the first conveying surface, at least one coupling conveyor having a third conveying surface adapted to move articles from the second conveying surface upstream and at least one return conveyor having a fourth conveying surface adapted to move articles from the third conveying surface to the first conveying surface. Each of the conveying surfaces may be defined by the upper surfaces of a plurality of powered rollers or traveling belts. Clusters of articles tend to recirculate around the recirculation bed and the first conveying surface and provide contact accumulation thereon as individual articles of the cluster are pulled away along the first conveying surface.

Airless Accumulation Conveyor

View page
US Patent:
7364035, Apr 29, 2008
Filed:
May 25, 2006
Appl. No.:
11/420248
Inventors:
Harry T German - Belding MI, US
David H Cotter - Coopersville MI, US
Wynn M Pelak - Rockford MI, US
Dennis J Schuitema - Ada MI, US
Assignee:
Dematic Corp. - Grand Rapids MI
International Classification:
B65G 13/06
US Classification:
19878103, 198790
Abstract:
An accumulation conveyor and method, according to the invention, includes providing a plurality of tandem accumulation zones, each of the zones including a conveying surface and at least one drive roller selectively driving the conveying surface. A drive member below the conveying surface extends a length of the plurality of tandem accumulation zones. Each of the zones includes a clutch roller rotated by the drive member and an electromagnetic clutch. The clutch selectively transfers rotation of the clutch roller to the drive roller to drive the conveying surface. The clutch may be made up of a pair of concentric cylinders aligned in a vertical plane and a force transmission member between the concentric cylinders with the force transmission member transmitting force between the concentric cylinders when the clutch is electrically actuated. The clutch may be a wrapped-spring clutch.

Roller Transport Conveyor And Method

View page
US Patent:
7841461, Nov 30, 2010
Filed:
Oct 6, 2008
Appl. No.:
12/246015
Inventors:
Thanh V. Nguyen - Wyoming MI, US
Dennis J. Schuitema - Ada MI, US
Mark S. Harkema - Grand Rapids MI, US
Wayne A. Moshauer - Rockford MI, US
Assignee:
Dematic Corp. - Grand Rapids MI
International Classification:
B65G 23/44
B65G 47/00
US Classification:
19878103, 19878109
Abstract:
A roller transport conveyor and method provides a device for conveying items along a plurality of rollers, in which the device may be set up and operated and serviced by manually raising and lowering one or more contact members that transmit force from a spring to urge a drive belt into contact with an underside of the rollers. The contact member is adjustable by raising and lowering the contact member to expand and contract the spring, or by raising and lowering a base on which the spring is supported, so that the drive belt may be engaged with and disengaged from the rollers. A gravity take-up includes a mass suspended from a cable that is routed to a pulley having the drive belt reeved thereon. The cable is wound upon a winch that compensates for belt stretch, or for belts of various lengths.

Reducing Drag On The Web Of A Positive Displacement Sorter

View page
US Patent:
8167116, May 1, 2012
Filed:
Sep 16, 2009
Appl. No.:
12/560612
Inventors:
Dennis J. Schuitema - Ada MI, US
Stephen C. Wolf - Grand Rapids MI, US
Kenneth J. Kooistra - Byron Center MI, US
David M. Berghorn - Waterford MI, US
Assignee:
Dematic Corp. - Grand Rapids MI
International Classification:
B65G 47/10
US Classification:
198617, 19837002, 19837007
Abstract:
A method of reducing drag on the web of a positive displacement sorter is used with a web made up of a plurality of parallel slats interconnected at their opposite ends with chain assemblies in an endless loop. A plurality of pusher shoes each travel along at least one of said slats. The sorter further includes a driven sprocket assembly and a non-driven sprocket assembly. Each of the sprocket assemblies includes at least two sprockets on a shaft, each for engaging one of the chain assemblies. The sprocket assemblies support the chain assemblies at opposite ends of the web. The method includes auditing the sorter including determining if the slats are skewed with respect to the direction of travel of the web. If it is determined that the slats are skewed, then the chain assemblies and the non-driven sprocket assembly are modified. The chain assemblies are modified by adding side thrust wheels on opposite sides of the web.
