Problems solved by technology

[0005] The snapping mechanisms of these known service assemblies have the disadvantage that the snapping of service assemblies that are not correctly positioned or not yet fully locked at the station requiring service is often quite difficult
In other words, especially when the service assembly is still in motion, it sometimes happens that when the pivotally mounted snap rail provided with the snap recess is mechanically snapped onto the guide rail provided on During the process of attaching the snap bolts, the snap bolts will not be caught, so that the service component will first pass over the corresponding station, so a new snap attempt has to be started

Embodiment Construction

[0016] FIG. 1 schematically shows a front view of a textile machine for producing cross-wound bobbins, in this embodiment an automatic cross-winder 1 . Automatic cross-winders 1 of this type generally have a large number of similar stations 2 between their end frames 35, 36, at which stations the spinning machines have been processed in a ring spinning machine (not shown) connected upstream of the production process. The bobbin 9 produced on (shown in the figure) is rewound to form a high-capacity cross-wound bobbin 11. The finished cross-wound bobbins 11 are conveyed to a cross-wound bobbin conveyor 21 dedicated to the textile machine by means of an automatically operated service unit 23, preferably by means of a so-called cross-wound bobbin doffer, and are then transferred to a A bobbin loading station (not shown) at the head or the like.

[0017] Automatic cross-winders 1 of this type usually also have a logistics mechanism in the form of a bobbin transport system 3 , in w...

Abstract

The present invention relates to a service assembly for self-actuating support of cross-wound bobbin producing textile machine. The service assembly has multiple similar workplaces, which are provided with numerous thread handling devices. A device (19) is provided for mechanically engaging the service assembly with a workplace. The engaging device has two movably arranged catch elements (43A,43B), which are arranged and controlled so that they slide consecutively in a catch opening (20), and in the process the service assembly (23) is located and catched at a workplace (a) requiring service, so as to accurately locate the service assembly at the catch position.

Description

technical field [0001] The invention relates to a service assembly according to the preamble of claim 1 for the automatic feeding of a textile machine for the production of cross-wound bobbins. Background technique [0002] Servicing assemblies for the automatic servicing of workstations of textile machines or similar textile machines producing cross-wound bobbins, and having a mechanism for mechanically locking them at the workstation requiring service, are known and described in numerous patent applications and in various There are detailed descriptions in other references. [0003] For example from DE 2117585 A a movable maintenance device is known which travels along the spinning stations of a ring spinning machine and has a snap-in mechanism whose mechanical positioning can be activated by an actuatable switching cam to target mode actuation. In this known snap-in mechanism, according to a first embodiment, a pivotably mounted positioning roller is provided which is p...
