Publication number: 20080078708Abstract: A device for orienting flat mail items with a u-shaped conveying channel has a base belt guided over reversing rollers and driven at a predetermined speed. First and second guiding belts are driven at the predetermined speed and guided over deflection rollers. A flat mail item is transported over a defined path standing on its narrow side. The first guiding belt is inclined as a lateral reference belt for frictional orientation of the mail items and guided via fixed deflection rollers. The second guiding belt is guided by pression deflection rollers so that the conveying channel possesses a defined minimum channel width to orient thin mail items on the base belt. For the mail items located in the conveying channel, the second guiding belt deviates against a spring force of a deflection roller bearing, with the second guiding belt possessing a lower coefficient of friction than the lateral reference belt.Type: ApplicationFiled: November 18, 2005Publication date: April 3, 2008Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Holger Schererz, Andre Tolksdorf

Publication number: 20070274819Abstract: To process large stamped letters, machine readable large letters are placed with the stamp facing upwards in a sorting station on a conveying means that leads them to further processing stations, has a reference edge in the conveying direction and is inclined in the conveying direction. The letter edge parallel to address lines, in proximity of which the stamps are located, rests against the reference edge. The stamps are automatically cancelled by a canceling device arranged over the leading-away conveying means and at a lateral spacing from the reference edge which corresponds to the spacing of the stamps from said letter edge. The large letters are then rotated through 90° as they are conveyed onwards with the shorter letter edge resting against the reference edge, by a locally fixed rotation element, so, like the standard letters, they rest with their longer letter edge on the reference edge, as is required for further processing.Type: ApplicationFiled: February 3, 2005Publication date: November 29, 2007Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Holger Schererz, Juergen Francke

Publication number: 20070176348Abstract: In a stacker, a mail item to be stacked is propelled against a stop wall at a stacking point by a stacking roll. A controlled driven underfloor belt and a stack support are displaced from the stack as the stack grows. The mail item to be stacked meets the preceding, already stacked item at an acute angle. Before it is stacked the mass of each item is determined. Stacking forces are measured with a measurement device in a preceding test phase the target values for the stacking pressures and the braking curve of the stacking roll up until the mail items have reached the stop are defined and stored based on statistical analyses in accordance with the mass of the mail items to be stacked. The speed of the respective mail item is reduced according to the braking curve assigned to the determined mass of the mail item.Type: ApplicationFiled: March 8, 2005Publication date: August 2, 2007Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Holger Schererz, Armin Zimmermann, Thomas Froehlich
