Workstation of a textile machine

Abstract

The invention relates to a workstation of a textile machine comprising an open-end spinning device for the production of a thread, a cone winding device for winding the thread into a cross-wound bobbin, a pivotably mounted suction nozzle connected to a low-pressure network of the textile machine for receiving the thread from the surface of the cross-wound bobbin, and a storage nozzle connected to the low-pressure network for the temporary storage of a thread excess created in the form of a thread loop during the startup of the workstation. According to the invention, it is provided that the suction nozzle (4), which has a relatively high suction air consumption, and the storage nozzle (60), which has significantly lower suction air consumption, are connected to the low-pressure network (20) of the textile machine such that the suction nozzle (4) can be decoupled from the low-pressure network (20), if necessary, independently of the storage nozzle (60).

Description

technical field [0001] The invention relates to a work station of a textile machine according to the preamble to the first aspect of the invention. Background technique [0002] Such stations are known, for example in connection with open-end rotor spinning machines, and are described in considerable detail in DE 10 139 073 A1 or in DE 101 39 075 A1. Such open-end rotor spinning machines usually have a large number of identical workstations arranged next to each other, which are each equipped with an open-end spinning device and a winding device. At each of the numerous stations, a fiber sliver supplied, for example, in a spinning pot is spun into a yarn by means of a spinning device, and the yarn is subsequently wound into a cross-winding bobbin with the aid of a winding device. In this case, the workstations described in DE 101 39 073 A1 or DE 101 39 075 A1 are designed as self-sufficient workstations. That is, these stations are configured such that they can automatical...

Problems solved by technology

[0003] The advantages of an open-end spinning machine with these well-equipped stations are, on the one hand, the high flexibility to process different yarn lots and, on the other hand, the overall efficiency compared to "normal" open-end spinning machines, This is because these stations don't have to wait for the splicing unit to move back and forth along the station when needed, whereas in a "normal" open-end spinning machine the movement of the splicing unit back and forth would cause the waiting in the splicing of the stations again and again time

[0004] However, due to the need for pneumatic storage nozzles and above all for the station's own suction nozzles, such a fully equipped station consumes a lot of air during the splicing process, with the result that the number of stations capable of simultaneous splicing is limited to twelve around
