Abstract

Open-end rotor spinning machine (1) with at least one machine-length belt drive, wherein rollers for guiding and / or for tensioning the tangential belt (9) are used, characterized in that the guide and / or tension rollers (10) are formed fan-like.

Description

The invention relates to an open-end rotor spinning machine with at least one machine-length belt drive, wherein rollers for guiding and / or for tensioning the tangential belt are used.

In open-end rotor spinning machines to accumulate significant amounts of dust particles, lint and Avivage- and dirt particles that float in the air and of which a subset deposited on respectively in the open-end rotor spinning machine. The development of dust and dirt depends on the material to be processed and the selected production parameters, such as the winding speed or the waxing. In addition, the release of such particles from the friction is favored, the running thread is exposed at some points in the threadline, for example on thread guides.

In the case of an open-end rotor spinning machine, for example, the contamination can affect, for example, functional aggregates but also the drive devices. These contaminants can lead to functional and quality problems of the cheese to be produced but also to the destruction of the drive devices. Because also on the guide respectively tension rollers of the drive belt are deposited fibers and finishing agents, which lead by their uneven distribution to an imbalance of the guide and / or tensioning rollers. This unbalance may then lead to destruction of the holder of the guide and / or tension rollers and / or the drive belt.

In order to reduce such functional problems or quality problems, it is known to use various units in the open-end rotor spinning machine, which serve for cleaning.

Open-end rotor spinning machines are described in detail in the textile industry in various embodiments and in numerous patent applications.

By the DE 198 36 065 A1 a so-called automatic open-end rotor spinning machine is disclosed in which both the working organs of the spinning device and the working members of the winding device are acted upon by machine-length drive means.

In the field of spinning devices tangential belts for driving the spinning rotors and the opening rollers and a machine-length drive shaft for applying the sliver feed cylinder are arranged, the associated drives are installed in a machine end side arranged machine frame.

In the field of winding devices, the bobbin drive rollers are arranged on machine-length bobbin drive shafts and set the traversing yarn guide on a reciprocating yarn guide rod, which are connected to a machine end side arranged traverse gear.

Furthermore, thread take-off devices are available whose driven take-off rolls are also part of a machine-length drive shaft.

In the DE 43 09 947 A1 a so-called semi-automatic open-end rotor spinning machine is described. The workplaces of such semi-automatic rotor spinning machines preferably each have a sliver draw-in cylinder which can be driven individually, while, for example, the spinning rotors, the opening rollers and the coil drive rollers are acted upon by machine-length drive means.

A disadvantage of open-end rotor spinning machines according to the prior art is that the guide and / or tension rollers of the drive belt partly so dirty that the holder of the guide and / or tension rollers or the drive belt itself are destroyed.

Starting from open-end rotor spinning machines of the aforementioned type, the present invention seeks to propose an open-end rotor spinning machine, in which the contamination of the guide and / or tension rollers is reduced.

This object is achieved by the characterizing features of claim 1.

An advantageous embodiment is the subject of the dependent claims.

To solve the problem is provided according to claim 1, that the guide and / or tension rollers are designed like a fan.

If the guide respectively tension rollers are constructed like a fan, the amount of depositing fibers and lubricants between the cleaning intervals is reduced. This reduces the likelihood that uneven distribution of the contaminant mass will take on dimensions that result in such high imbalance that the guide or tension rollers and / or the drive belt will be destroyed.

Another advantage of the embodiment according to the invention is that also the cleaning of the drive elements, such as the blowing out with compressed air of the guide perspective tension rollers is easier to perform.

In an advantageous embodiment, the guide and / or tension rollers of the opening roller drive are designed according to claim 2 lüfterradartig.

In the area of the opening rollers, which dissolve / comb out the sliver up to individual fibers, particularly a lot of fiber fly arises, so that this drive device is particularly predestined for the inventive design of the guide respectively tension rollers.

As described in claim 3, preferably the guide respectively tension rollers of the rotor drive are designed like a fan.

Also in this area, in which the individual fibers are transported by means of negative pressure in the rotor, the advantages of the present invention are particularly well to fruition. Because of the prevailing negative pressure and naturally occurring gaps in the textile machine housing, the negative pressure in the textile machine housing continue, and causes polluted ambient air is sucked. The polluted ambient air contains mainly fibers, but also particles of the lubricants, which are deposited on the drive elements.

In the following the invention will be explained in more detail by means of an embodiment with reference to the accompanying drawings.

The drawings show:

In the present embodiment, the open-end rotor spinning machine 1 two machine sections 2 . 3 as well as two machine end racks 4 . 5 on.

The machine sections 2 . 3 are in turn subdivided into twelve jobs, the individual jobs, for example, each via an opening roller 6 feature.

In the machine end frame 4 is, among other things, an electric motor drive 7 and an associated drive wheel 8th for the machine-long tangential belt 9 arranged while the machine end frame 5 a guide respectively tensioning roller 10 for the tangential belt 9 having.

The drive of the opening rollers 6 via a Spindelwirtel of the machine-tangential belt 9 ,

The guide respectively tensioning roller 10 is on a holder 12 stored. The open contour 11 creates a fan-like appearance and results in fewer fibers and lubricants relative to the same time unit on the guide-perspective tension roller 10 can deposit.
