Patent number: 8746437Abstract: The invention provides a method which minimizes the gaps between packages to the minimum required by the sorter. The gapping required to allow scanning the identification label(s) will be done first, then another gap adjustment (to reduce gaps) is done immediately after scanning. The induction control system requires inputs from additional sensors which are necessary to obtain certain package dimensions. This information (dimensions of the packages) is used by the control algorithm to calculate or select from a table based on package geometry, the minimum (or optimum) gaps required for scanning and by the sorter.Type: GrantFiled: May 10, 2012Date of Patent: June 10, 2014Assignee: Siemens Industry, Inc.Inventors: Ricardo N. Schiesser, Clyde Ko, Rhonda J. Verploegen

Patent number: 7243777Abstract: A method and apparatus for sorting or pre-sorting objects contains a system of conveyors and crossover diverters incorporating the topology of an omega network. The sorter interconnects a series of perfect shuffle networks, interleaved with banks of crossover switches. Collision avoidance is implemented by controlling flow on accumulator conveyors entering the crossover switches. Extra banks of crossover switches may be added to provide redundancy and load-balancing capabilities to the system.Type: GrantFiled: December 5, 2005Date of Patent: July 17, 2007Assignee: Siemens Corporate Research, Inc.Inventors: Dan Reznik, Christoph Holst, Ricardo N.

Patent number: 7233840Abstract: A system and method for manipulating articles includes providing a bed having at least one conveying surface. The conveying surface is adapted to move articles in a direction of conveyance from an upstream end to a downstream end of the bed. At least one sensor is provided to determine the position of any articles on the bed. Selected articles are moved in the direction of conveyance at a speed that is generally higher than articles traveling on the bed that have yet to be manipulated and the articles are selectively rotated.Type: GrantFiled: August 14, 2006Date of Patent: June 19, 2007Assignee: Siemens Energy & Automation, Inc.Inventors: Ricardo N.

Patent number: 7156220Abstract: A method for handling trays for use with an article sorter includes providing a conveying surface along a plurality of sorter units and conveying empty trays along the conveying surface. The empty trays that are being conveyed along the conveying surface are stopped with a tray stopping device that is positioned at least partially below the conveying surface and operable to project a portion of the tray stopping device above the conveying surface to engage and stop an empty tray. The stopped empty trays are moved from the conveying surface to the tray support areas in a direction generally transverse to the conveying surface. The empty trays are at least partially filled at the tray support areas, and the partially filled trays are moved from the tray support area onto the conveying surface.Type: GrantFiled: June 16, 2005Date of Patent: January 2, 2007Assignee: Siemens Energy & Automation, Inc.Inventors: Douglas E.
