Embodiment Construction

[0021] figure 1 A half of an open-end spinning machine known per se, designated by reference numeral 1, is shown in FIG. Open-end spinning machines of this type generally have a large number of workstations 2 each equipped with a spinning mechanism 3 and a winding device 4 .

[0022] In the spinning boxes 3 , the fiber strips 6 fed to the spinning pots 5 are spun respectively to form yarns 7 , which are then wound on the winding device 4 to form cross-wound bobbins 8 . As shown, the winding device 4 is equipped in this example with a creel 9 for rotationally holding the cross-wound bobbin 10 and with a friction drive for the cross-wound bobbin 10 or cross-wound bobbin 8 The bobbin drum 11.

[0023] Most double-row open-end spinning machines 1 also frequently have between their two rows of work stations a bobbin conveyor 12 through which the completed cross-wound bobbins 8 are transported away.

[0024] A service unit 16 , for example a so-called piecing carriage, is arrange...

Abstract

The invention relates to a service assembly for the automatic supply of workstations of a textile machine which produces crosswound bobbins, in particular an open-end spinning machine, having a control device, an auxiliary-thread supply and disposal device, and a manipulator having a thread-guiding device which can be displaced for fixing a newly joined crosswound bobbin tube and for producing a thread reserve in the direction of the bobbin frame. According to the invention, there is provision for the control device (24) of the service assembly (16) to be configured in such a way that the thread-guiding device (59) can be pulled back after the transfer of the newly joined thread (7) to the crosswound bobbin sleeve (10) by means of a manipulator (48), if required before the production of a thread reserve.

Description

technical field [0001] The invention relates to a service unit for a textile machine for producing cross-wound bobbins. Background technique [0002] Service assemblies for automatic feeding of workstations of textile machines (in particular open-end spinning machines) for the production of cross-wound bobbins are known in several embodiments, with auxiliary yarn feeding and handling devices for feeding new A device for fixing the piecing yarn to a cross-wound bobbin held in a creel and a device for creating a thread reserve. [0003] For example, DE 44 32 702 describes a service assembly with a pivotably mounted yarn supply tube, a yarn guide arranged in the region of the yarn supply tube and a multifunctional slide for producing a yarn reserve. In this example, the yarn supply bobbin can be selectively connected to a source of suction or compressed air and pivoted to different working positions. The yarn transfer device configured as a pivotably mounted yarn guide plate ...
