Patent number: 9108224Abstract: A sorting installation and a sorting method jointly sort two kinds of flat mail items. For each article to be sorted, a value that a prescribed sorting feature assumes for the article is measured. The article is transported by a first transport device to a separating filter. An article of the first article kind is redirected in a first outward-transfer device. On the basis of the ascertained sorting feature value, one sorting output from a first set of sorting outputs is selected. The article is transferred outward to the selected sorting output from the first sorting output set. An article of the second article kind is redirected to a second transport device and transported to a second outward-transfer device. On the basis of the ascertained sorting feature value, one sorting output from a second set of sorting outputs is selected.Type: GrantFiled: September 13, 2012Date of Patent: August 18, 2015Assignee: Siemens AktiengesellschaftInventors: Holger Schererz, Rolf-Peter Skrdlant, Frank Voss

Patent number: 7178714Abstract: The invention relates to a container for flat objects in a vertical position, comprising a base, two lateral longitudinal sides and two front sides, the flat objects being aligned with their largest surfaces facing the front sides. At least one front side consists of at least one material web, whose axes run parallel to the base, which is mobile in relation to the front side and can be displaced downwards into a gap in the base. The material web is flexible and thin and is suspended by its ends that run perpendicular to the longitudinal sides between two bars. The lower bar is configured in the gap in the base and is displaceable and the upper bar can be displaced between the base and the upper edge along the front delimitation of the longitudinal sides.Type: GrantFiled: December 30, 2004Date of Patent: February 20, 2007Assignee: Siemens AGInventor: Rolf-Peter Skrdlant

Patent number: 7070180Abstract: The present invention relates to a method and a device for stacking flat mailings, in which the thickness of each individually conveyed mailing that is to be stacked is detected within a main control loop. The underfloor belt is displaced away from the stacking location by a distance that corresponds to the measured thickness minus a specific distance by means of a stack support for the arriving mailing. The stacking force is measured at different heights in the area of the stacking roll in a static correcting control loop and is re-regulated by moving the underfloor belt within set point values established for the allowed stacking force ranges once each mailing has reached the stop.Type: GrantFiled: November 24, 2004Date of Patent: July 4, 2006Assignee: Siemens AktiengesellschaftInventors: Bernd Lindenmayer, Dietmar Oexle, Rolf-Peter Skrdlant

Publication number: 20050189704Abstract: According to the invention, the items to be posted are held by a stacking support which can be displaced in a stacking direction and is coupled to a flush-mounted strip on which the stack is arranged, and by a parallel stacking wall which is located in a vertical position on the stacking spot, oriented towards an abutment wall. Said items to be posted are supplied and stacked by means of stacking belts and a stacking roll which projects from the stacking wall and is located at the entrance to the stack receiving installation, close to the abutment wall, said stacking roll being mounted in a deflectable manner. A connecting element is used to connect the stacking roll housing to the force transducer of a device for measuring the stacking pressure perpendicularly to the resulting belt force exerted on the stacking roll.Type: ApplicationFiled: February 9, 2005Publication date: September 1, 2005Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Dietmar Oexle, Rolf-Peter Skrdlant

Patent number: 6776407Abstract: The present invention relates to a system and method for stacking objects in a stack. The objects may be flat flexible objects with front and back edges being narrower than side walls. Accordingly, the objects may comprise mail pieces. Per the invention, the mail pieces are directed to a stacker. The stacker comprises an impact wall with abutting installation and limiting walls. Accordingly, the stack may be formed therebetween with the installation wall being urged towards the limiting wall so as to sandwich the stack. At least one diverter element or vain is included upstream from the stacker. A roller of a conveying element is positioned upstream from the upper most vain. An object is directed towards the impact wall. When the objects leading edge impacts the wall, the vain or roller closest to the trailing portion of the object causes the trailing portion to be urged towards the stack. The vains may be pivoted while the roller made to turn in a select manner.Type: GrantFiled: January 21, 2003Date of Patent: August 17, 2004Assignee: Siemens AGInventors: Bernd Lindenmayer, Dietmar Oexle, Rolf Peter Skrdlant
