Definitions

  • the invention relates to a thread guide member for removing a thread from the yarn formation zone of a spinning machine according to the preamble of Claim 1.
  • a thread guide element in the form of a thread guide tube is, for example known from DE 42 35 024 A1. This has an entrance area that of the thread formation zone of the thread on the spinning machine is facing and a part or area that the thread formation zone is turned away. These two areas are tubular and theirs the two axes intersect at an angle.
  • the spun thread enters the thread guide tube is in the known thread guide tube deflected in this and leaves the thread guide tube via the the area facing away from the thread formation zone.
  • the thread guide tube is composed of several individual parts that are firmly connected are. So it is known in the prior art, these individual parts firmly together to glue.
  • a thread guide tube is known, the Thread formation zone facing part and its part facing away from this are integrally formed with each other.
  • the central axes of these two parts also enclose an angle.
  • this one has an insert Forms an obstacle to the running thread. This insert is interchangeable educated.
  • GB 21 15 840 A which discloses a generic guide tube
  • a device is known that one in an open-end spinning device Treat the spun thread pneumatically can. This is arranged in the area of the thread guide tube, for which purpose this is divided into sections into which pneumatically acting inserts are used are.
  • the known thread guide tubes have the disadvantage that they are used are inflexible in practice because they have a fixed assignment of the thread formation zone facing part and the facing part. It is therefore not possible to handle them independently or use and replace if necessary.
  • the object of the present invention is to provide a thread guide tube of this type to design that its possible uses are increased significantly, so that it is also for monitoring functions with regard to the thread and can be used to control the spinning machine, and that the Disadvantages of the prior art can be avoided.

There through becomes a flexible. Design of the thread guide tube, in particular in terms of cost, possible.
  • the invention is the thread guide tube in the region of the first section, which faces the thread formation zone, with a separation point Mistake. This ensures that the thread guide tube is easier to clean possible and interchangeable inserts, e.g. a damming element to increase the rotation of the thread, easier in the thread guide tube can be exchanged.
  • the separation point between the two sections is particularly advantageous arranged the thread guide tube.
  • the thread guide tube is at least in the area which faces the thread formation zone, is designed as a closed tube, whereby a particularly safe guidance of the thread is possible.
  • the area facing away from the thread formation zone can also be used with the same Advantages should be designed accordingly.

It is particularly advantageous if the thread guide tube is divided into two parts, at least one of which is a coupling element for connecting the two parts. This makes it possible to create a secure connection that is also just as easy to solve can be.
  • the coupling element is particularly favorable as a bayonet or clip connection trained both parts of the thread guide tube easily and safely connects with each other and still be solved easily and without tools can be.
  • this is in the area of the separation point via a thread Coupling element connected together.
  • the two parts of the Threads advantageously work together so that a secure connection that arises between the two parts of the thread guide tube is easily detachable and can be restored just as easily.
  • the Connection more stable.
  • the senor is in the range of Section of the thread guide tube arranged, the thread formation zone is turned away. This makes it easier to replace the sensor. It is also particularly advantageous for the sensor in the region of the section to arrange the thread guide tube, the thread formation zone is facing. This makes it possible to monitor the yarn, especially advantageous at a thread formation zone very close Place. It becomes possible, for example, if the sensor is considered a monitoring for the quality of the thread is already formed after short time or thread length after the thread has been spun this Detect errors.
  • the senor is used as Sensor for monitoring the channel inside the thread guide tube educated. This advantageously means that e.g. a pollution of the channel can be easily recognized.
  • the sensor is used as a sensor for monitoring the presence a thread in the channel of the thread guide tube, whereby a Thread breakage is quickly recognized, so that the control of the spinning machine can react accordingly quickly.
  • the senor is designed as a sensor for Monitoring the thickness and / or the mass of the thread is formed. Thereby it is possible to monitor the quality of the spun thread and quickly identify errors such as thick or thin spots.
  • the sensor is for monitoring of the thread is designed as a detector for foreign fibers in the thread. This makes it possible to produce a high quality thread because the presence of foreign fibers in the thread is quickly reacted to can. Through appropriate measures, such as Turning off the spinning station, can prevent unwanted components in the thread be incorporated. The components already spun in can be cleaned out again.
  • the separation point is particularly favorable essentially transversely to the axis of the Thread guide tube arranged or formed. This will be advantageous achieved that the thread guide tube is particularly flexible and separating and reassembling is particularly easy and safe can be done quickly.
