Publication number: 20090260950Abstract: In order to do away with the need for large items of laundry which are spread out by a spreading arrangement (12) such that they hang down freely upstream of the feed conveyor (11) to be raised manually, as they are fitted manually into loading clamps (27), until they hang down freely, it is known for the loading clamps (27) to be displaced to the spreading arrangement (12) on obliquely upwardly directed conveyors (20). The large items of laundry are thus raised mechanically. For this purpose, the loading clamps (27) are arranged on carriages which can be displaced on upwardly directed rails. The disadvantage here is that the empty loading clamps have to be moved downwards on the rail again by the carriage before the next item of laundry can be fitted into the loading clamps (27). The invention makes provision for the loading clamps (27) to be arranged on conveyors (20) having endless toothed belts (21). The loading clamps (27) can thus be driven in circulation.Type: ApplicationFiled: June 19, 2008Publication date: October 22, 2009Inventors: Engelbert Heinz, Friedhelm Mehrhoff, Jurgen Sielermann

Publication number: 20090250311Abstract: The invention relates to a method and to a device for creating a product flow according to a predefined sequence (S). The products (A, B, C) are fed from different feed flows of a grouping path (G) and there, according to the sequence (S), are deposited onto a conveyor (10,10) with a closed revolving path (U). According to the invention a repair function is realised in which the products (A, B, C) are then only transferred from the conveyor to a further-processing station if the sequence (S) is correct and all products (A, B, C) are present with the desired quality. Otherwise, the products (A, B, C) are led by the continuously operated conveyors (A, B, C) back to the grouping path (G). Here, the error is corrected by way of the deposition of the missing product (A, B, C), whilst the deposition of new products (A, B, C) is interrupted. For error correction, one may previously provide a discharge of a defect or wrong product (A, B, C).Type: ApplicationFiled: April 3, 2009Publication date: October 8, 2009Applicant: FERAG AGInventor: Werner Honegger

Publication number: 20010050206Abstract: An apparatus for transporting a plurality of automotive body styles along an assembly line. The apparatus includes a plurality of antler nests, at least one antler nest for each automotive body style to be processed on the assembly line. Each antler nest is transported along the assembly line by a carriage. An exchanging station is provided to exchange one antler nest for another. The antler nests can be exchanged while a rate of production on the assembly line is maintained.Type: ApplicationFiled: January 23, 2001Publication date: December 13, 2001Inventors: Keith A. Oldford, Michael R. Dugas, Velibor Kilibarda, Alan S. Kaufman, Karl G. Johnson

Patent number: 6318946Abstract: An interlock system prevents collision of handling equipment and damage to wafers in an automated wafer transport apparatus during manual control by an operator. Sensors are used to sense when wafer transport arms and wafer stage are both in their home positions. A controller is responsive to the sensors for operating the lockout system such that attempted activation of the transport arm by the operator is locked out unless both the stage and the arms are in their home positions. The lockout system preferably comprises normally closed electrical relays.Type: GrantFiled: March 31, 1999Date of Patent: November 20, 2001Assignee: Taiwan Semiconductor Manufacturing Company, LtdInventors: Yuh-Dean Tsay, Shih-Chieh Liao, Li-Ren Lin, Wen-Yao Chen

Patent number: 6264420Abstract: A device is provided for monitoring sheets from which cards with a monetary value and/or identity cards are punched, where the cards are arranged in rows on the sheets. The device is configured such that the number of cameras used is independent of the number of rows of cards. The device has a table on which at least two sheets can be laid. A camera can be moved along and across the table, and a conveyor device travels along the table above the camera.Type: GrantFiled: November 17, 1999Date of Patent: July 24, 2001Assignee: Louda Systems GmbHInventors: Arne Bieringer, Ernst-Norbent Krause
