Patent number: 6848568Abstract: A method, apparatus and software product for moving bulk materials effectively through a path gate in a distribution system provides at least two independently operable conveyors aligned in series such that the end of the first conveyor is adjacent to the beginning of the second conveyor with a pass gate positioned downstream of the two conveyors. In cases where the bulk material has formed into a cohesive block, the first conveyor is operated to bring the block near the second conveyor. Then, the first conveyor is slowed or stopped while the second conveyor is operated at a higher speed than the first conveyor. This action causes the portion of the cohesive block adjacent to the second conveyor to topple or break down, thereby breaking down the cohesiveness of the block and directing a portion of this toppled bulk material forward onto the second conveyor. Then, the second conveyor urges this portion of the bulk material toward the downstream path gate.Type: GrantFiled: August 6, 2002Date of Patent: February 1, 2005Inventor: Lawrence Gene Nibler

Patent number: 5613590Abstract: A device for feeding and distributing material which is loose or in single pieces to a plurality of collection points peripheral to the device itself comprising a main fixed support framework, a plurality of radial channels for transporting the material to the collection points supported by the framework, and a part for distributing the material to the transport channels, supported rotatably above the channels, whereto the material is fed and transferred by the latter through falling and distributed by rotation to the radial transport channels.Type: GrantFiled: December 23, 1994Date of Patent: March 25, 1997Assignee: Simionato S.P.A.Inventor: Paolo Simionato

Patent number: 5584640Abstract: A conveying system (43) is disclosed including a vertical auger (27) which receives material from a horizontal auger (25). The vertical auger is driven by a hydraulic motor (37) and the horizontal auger is driven by a hydraulic motor (35). A pressure response valve (89) responds to a pressure signal (93), representative of the load on the motor (37) driving the vertical auger to unload or bypass the motor (35) driving a horizontal auger. As the load on the vertical auger decreases, the valve (89) gradually communicates more flow to the motor (35) driving the horizontal auger, thus feeding more material (grain) to the vertical auger.Type: GrantFiled: April 20, 1994Date of Patent: December 17, 1996Assignee: Eaton CorporationInventor: Vernon A. Johnson

Patent number: 5523101Abstract: Uniform distribution of materials over a predetermined area of a receiver is assured by a multipurpose applicator wherein a gauging or metering device contacts materials on a conveyor to ensure that the materials are uniformly spread along the conveyor so that incremental movement of the conveyor results in a predetermined portion of the materials entering a distributor wherein it is agitated to form a cloud that will fall evenly over the predetermined area defined by a mask on the receiver. An electronic weighing device between the conveyor and the distributor may be used to achieved exact weight of portions.Type: GrantFiled: July 16, 1993Date of Patent: June 4, 1996Inventor: Clifford E. Fitch, Jr.

Patent number: 5472078Abstract: A single layer of spaced-apart rod-shaped articles of the tobacco processing industry is advanced sideways toward a transfer zone wherein successive groups of two or more neighboring articles are diverted along separate paths against a concave friction surface of an intercepting member. The friction surface directs at least some of the diverted articles into a chamber where the articles are gathered to form a supply of superimposed articles. A belt or chain conveyor is employed to draw a continuous homogeneous mass flow of articles from the chamber.Type: GrantFiled: July 14, 1994Date of Patent: December 5, 1995Assignee: Hauni Maschinenbau AGInventors: Wilfried Hoffmann, Gerd Sanmann, Joerg Foerster, Peter Trenkner

Patent number: 5411131Abstract: A non-synchronous plural conveyor system for transporting articles between work stations which operate at varying production rates. Each conveyor operates alternately in an accumulate or deliver mode such that articles may be placed thereon at a first station at a rate different from the rate they are removed at a second station.Type: GrantFiled: June 13, 1994Date of Patent: May 2, 1995Inventor: Richard P. Haegele

Patent number: 5373879Abstract: Elongated wood blanks are fed on a table toward a machining tool such as a planar. The leading end of each blank is engaged by a driven input roller at the upstream side of the tool and advanced by the input roller into engagement with the tool and past the tool. A driven advance roller downstream of the tool then engages each input end to draw the blank past the tool for machining the length of the blank. As soon as the leading end of a finger engages the advance roller, the input roller pressure on the blank is relieved and, when the trailing end of the blank passes the advance roller, the input roller is repositioned to engage the leading end of the next blank.Type: GrantFiled: October 26, 1992Date of Patent: December 20, 1994Assignee: Hoffmann & Kuhnhenrich GmbHInventor: Ludger Kuhnhenrich
