Publication number: 20050191164Abstract: The aim of the invention is to provide a device for effecting the positionally accurate conveyance of flat articles to be sorted to an input device for a sorting conveyor, whereby this device enables, in particular, even problematic articles to be sorted, such as e.g. bulk mailings, to be conveyed in a sufficiently accurate manner for the subsequent processing thereof. To this end, the invention provides that a draw-off unit (15), which periodically separates the flat articles to be sorted (6), feeds the flat articles to be sorted (6a) in separated form to a conveyor line (26), and a conveying unit (30), with a defined advance of the input device (8), transfers the separated articles to be sorted (6a) after these articles to be sorted (6a) have arrived at a predetermined location of conveyance of the conveyor line (26).Type: ApplicationFiled: April 25, 2005Publication date: September 1, 2005Applicant: SIEMENS SCHWEIZ AGInventors: Beat Fritsche, Thomas Zimmermann

Publication number: 20050146088Abstract: The present invention is directed to transferring flat objects to be sorted towards the input device of a sorting conveyor for sorting them. This is achieved by a picking unit which periodically individualizes the flat object for sorting, places the objects on a transporting path, and a transferring unit transfers the objects to be sorted, when they come in a predetermined position on the transporting path, to an input device at a defined advancement rate. The targeted advancement rate makes it possible to place the object to be sorted in a final defined position in the input device in such a way that the subsequent treatment thereof is carried out in a reliable and automated manner. The shape and structure of the object is not important, because prior to the object reaching the predetermined transport position, the targeted displacement thereof is carried out at an pre-set advancement rate.Type: ApplicationFiled: February 17, 2005Publication date: July 7, 2005Applicant: SIEMENS SCHWEIZ AGInventors: Beat Fritsche, Thomas Zimmermann

Patent number: 5845785Abstract: The invention relates to an apparatus for processing shipping articles provided with shipping addresses. The apparatus comprises a device for transporting the shipping articles along a transport path. A device is disposed in the transport path for automatically reading the shipping addresses. An assessment device automatically assesses the read shipping addresses. The individual shipping articles are selectively deposited into cells of an intermediate storage device disposed in the transport path following the reading of the shipping address. A detection device detects an association between each cell and the shipping article deposited therein and in response to an assessment of the shipping address by the assessment device, produces a first removal signal for removing the shipping article from the cell and conveying the shipping article back to the transport path.Type: GrantFiled: February 21, 1996Date of Patent: December 8, 1998Assignee: Grapha-Holding AGInventors: Jean Claude Oppliger, Thomas Zimmermann, Beat Fritsche
