Publication number: 20230416951Abstract: A method carries out an automatic can change process at a spinning station of a spinning machine where a sliver is delivered to a spinning device from a sliver can positioned underneath the spinning station using a movable can changer that includes a can gripper. A length of a sliver residue is predefined and stored. Once the predefined length of the sliver residue length has been reached, the sliver is separated while production of a yarn from the sliver is underway at the spinning station. The sliver is clamped at the sliver can with a fixed clamp on the can changer, wherein separation of the sliver is performed by, with the can changer, removing the sliver can with the clamped sliver from the spinning station, or additionally clamping the sliver with a movable clamp on the can changer and moving the movable clamp relative to the fixed clamp.Type: ApplicationFiled: November 12, 2021Publication date: December 28, 2023Inventors: Michael Ueding, Adalbert Stephan, Sebastian Fritz

Publication number: 20230416952Abstract: A method for carrying out an automatic can changing process at a spinning station of a spinning machine uses a movable can change. At the spinning station, a supply device delivers a sliver in a delivery direction from a sliver can positioned underneath the spinning station. The sliver is clamped with a clamp on the can changer and, once clamped, the silver is separated. after separation of the sliver, the supply device is driven counter to the delivery direction such that a sliver residue remaining at the spinning station is returned by the supply device and ejected from the spinning station.Type: ApplicationFiled: November 12, 2021Publication date: December 28, 2023Inventors: Michael Ueding, Adalbert Stephan, Sebastian Fritz

Publication number: 20230183889Abstract: A spinning machine and method separate a sliver delivered out of a sliver can at a spinning station of the spinning machine. The sliver is delivered out of the sliver can with a supply device at the spinning station in a delivery direction to a spinning device, and is guided by a sliver guide between the sliver can and the supply device. The sliver is clamped in the supply device at the spinning station. In order to separate the sliver, the supply device is driven counter to the delivery direction, wherein the sliver is returned by the supply device and, as a result, the clamping of the sliver in the supply device is released.Type: ApplicationFiled: April 13, 2021Publication date: June 15, 2023Inventors: Michael Ueding, Adalbert Stephan, Sebastian Fritz

Patent number: 6336258Abstract: A given plurality of empty round (cylindrical) cans are brought by a can carrier into an empty can magazine of a textile machine which produces a band output. These cans are taken from the can carrier, one after another, to be filled at a filling station from whence filled cans are sequentially moved to a just emptied can carrier in a full can magazine. This can carrier, after the receipt of a given plurality of filled cans, are transported out of the full can magazine. Subsequently, the can carrier, which, in the intervening time, has been emptied and is now to be found in the empty can magazine, is transported by means of an elevated crossover into the full can magazine, which has become free. For the well-timed release of a can carrier loaded with empty cans as well as the transporting of a can carrier from the filling operation loaded with filled cans, there is a Hold Station serving as a buffer zone for an empty can with its can carrier.Type: GrantFiled: December 19, 2000Date of Patent: January 8, 2002Assignee: Rieter Ingolstadt Spinnereimaschinebau AGInventors: Michael Ueding, Otmar Kovacs, Carsten Peter

Patent number: 6233904Abstract: The present invention concerns a procedure and an apparatus for the simultaneous transportation of one group of cans (31, 310, 311) in a row from a can rack (6, 60, 61)—the cans (3) being capable of being filled with fiber band—to a frame machine (2) and/or to another textile machine (4) or to a can depot (5). The group of cans (31, 310, 311) is brought in common with the can rack (6, 60, 61) for the filling of said cans (3) into a first work station (A1) on the frame machine (2). The can rack (6, 60, 61) remains at that point during the filling of the cans (3) of this can group (31, 310, 311) until, after the filling of all the cans (3) on the can rack, the can rack (6, 60, 61) then, once again with the cans, is transported to the additional textile machine (4) or to the can depot 5.Type: GrantFiled: May 1, 2000Date of Patent: May 22, 2001Assignee: Rieter Ingolstadt Spinnereimaschinenbau AGInventors: Otmar Kovacs, Michael Ueding

Patent number: 5661947Abstract: The invention relates to the filling of a flat can with fiber sliver by a textile machine which delivers a fiber sliver, such as a carding machine or a draw frame, whereby the flat can is moved under a stationary, rotating rotary plate. The invention significantly reduces the costs for the required movements of the flat can as compared to the state of the art. The process according to the invention for the traversing of a flat can during the filling process at a textile machine delivering a fiber sliver is realized in that the flat can is shifted laterally by tilting of the flat can around an axis in the return path of the traversing path. In the device according to the invention, the traversing mechanism is equipped with a tilting device. For this purpose, the tilting device is provided with a tilter and an axis around which the flat can is tilted.Type: GrantFiled: March 27, 1996Date of Patent: September 2, 1997Assignee: Rieter Ingolstadt Spinnereimaschinenbau AGInventors: Josef Ippy, Otmar Kovacs, Michael Ueding, Albert Kriegler

Patent number: 5651165Abstract: The instant invention relates to the deposit of the fiber sliver end after the filling of a flat can. It is the object of the invention to deposit and prepare the sliver end in the area of the filling station on a full flat can in order to facilitate automatic handling of the flat can during transportation as well as automatic handling of the sliver end on a spinning machine at the least possible cost. The invention assumes that the positions between outlet (15) of the rotary plate (12), severing device (18) and flat can (1) in relation to each other are adjustable and that an influence on the point of deposit of the sliver end and on the length of the sliver end results from this selected setting.Type: GrantFiled: December 15, 1995Date of Patent: July 29, 1997Assignee: Rieter Ingolstadt Spinnereimaschinenbau AGInventors: Bernhard Mohr, Michael Ueding, Michael Strobel, Albert Kriegler
