Definitions

  • the invention relates to a thread guide member for the removal of a thread from the yarn formation zone of a spinning machine according to the preamble of Claim 1.
  • Such 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 both 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 it are integrally formed with each other.
  • the central axes of these two parts also enclose an angle.
  • In the area of the transition of the two Sections of the thread guide tube has an insert that one Forms an obstacle to the running thread. This insert is interchangeable educated.
  • 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 have facing part and the facing part. As a result, it is not possible to handle them independently or use and replace if necessary.
  • the object of the present invention is such a thread guide tube to design that its possible uses are increased significantly, so that it can also be used for other or additional tasks and that the disadvantages of the prior art can be avoided. This object is achieved by the features of claim 1 solved.
  • the inventive design of the thread guide tube with a separation point is advantageously achieved that the thread guide tube is divisible is and there will be the possible uses and the design options significantly expanded for the thread guide tube. It is now possible, e.g. to design the thread guide tube so that only, e.g. in the event of wear, individual parts of the thread guide tube are replaced, without insert, e.g. within the thread guide tube, exchanged Need to become. Otherwise it is possible e.g. the thread guide tube to design from different materials, new and different Use materials for different sections of the thread guide tube and to make it more versatile and cost-effective.
  • the thread guide tube with a separation point in the Area of the second section of the thread guide tube that of the thread formation zone is turned away, is achieved particularly advantageously that a Division of the thread guide tube into an area that is very low Has wear and one with a planned higher wear.
  • This provides a flexible design of the thread guide tube, in particular in terms of cost, possible.
  • the thread guide tube in the area of the first Section facing 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. on Barrier element to increase the rotation of the thread, in the thread guide tube can be exchanged more easily.
  • the separation point between the two sections is particularly advantageous the thread guide tube arranged. This is particularly beneficial for that Clean.
  • 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.
  • the two own Areas of the thread guide tube each have a central axis, which is below cut at an angle. This makes it possible to thread cheap Properties to spin. It is particularly advantageous if the thread guide tube is divided into two parts, at least one of which is a coupling element to connect the two parts. This makes it possible to create a secure connection that is 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 easily and without tools can be.
  • this is in the area of the separation point via a thread configured coupling element connected together.
  • the two parts the thread work together advantageously so that a safe Connection between the two parts of the thread guide tube is created, which is easily detachable and can be restored just as easily.
  • the invention takes part of the thread guide tube in the area of the separation point the other part in his Inside on. This will ensure that the two parts are aligned communicate with each other and during assembly and also in operation a guide of the two parts to each other the connection makes it easier to handle and more reliable. At the same time, the Connection more stable.
  • part of the thread guide tube carries a sensor.
  • the sensor directly on the thread guide tube can be arranged, because of the divisible design is achieved that, if necessary, parts of the thread guide tube can be replaced without removing the sensor at the same time must be, or it can be just as advantageous that the Sensor itself can be replaced by another sensor without the entire thread guide tube must always be replaced.
  • the inventive design of the thread guide tube opens the particularly inexpensive option of a sensor on the thread guide tube to be arranged without this affecting the life of the thread guide tube or its wear parts are bound. It is also beneficial possible to place the sensor near the separation point, so that a easy cleaning and monitoring of the sensor is possible.
  • a further development of the invention is the sensor in the area of the section of the Thread guide tube arranged facing away from the thread formation zone is. This makes it easier to replace the sensor. Especially It is also advantageous for the sensor in the region of the section of the thread guide tube to be arranged facing the thread formation zone. Thereby it is possible to monitor the yarn, particularly advantageously a point very close to the thread formation zone. It becomes possible, for example, if the sensor is used as a monitor for the quality of the thread is formed after a short time or thread length, after the thread is spun to find this mistake.
  • the senor is used as Sensor for monitoring the channel inside the thread guide tube educated.
  • 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 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 for monitoring of the thread 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.
  • Figure 1 shows a thread guide tube 1 designed according to the invention a channel 10 for guiding a thread from the thread formation zone Spinning machine, e.g. B. from the rotor of an open-end rotor spinning machine or comparable devices, e.g. a friction spinning machine.
  • the Thread guide tube 1 of Figure 1 has a first section 11, the Thread formation zone is facing and a second section 12 of facing away from the thread formation zone. The spun thread enters the area of the first section 11 in the channel 10 and runs in this to the end 121 of the second section 12.
  • the thread is in the thread run after the thread guide tube 1 between two rollers (not shown) pinched, which rotate in opposite directions, so that with the help of these so-called Take-off rolls of the thread through the thread guide tube is withdrawn from the thread formation zone. So the thread is through that Pulled through the interior of the channel 10.
  • the first section 11 of the thread guide tube 1 has a central axis 110 which is aligned with the central axis 120 of the second section 12 encloses an angle. This angle is advantageous a size in the range between 110 ° and 140 °, preferably 125 °.
  • Through this course of the channel 10 is a through the thread guide tube guided thread at its deflection on the baffle element 2. This is in a known manner advantageous for the formation of the thread.
  • the thread runs over the surface 20 of the baffle element, causing the in the thread formation zone granted twist is pent up in the thread, causing thread formation facilitated.
  • the baffle element 2 is firmly glued into the first section 11.
  • the first section 11 essentially consists of original two individual parts 21 and 22, which are also firmly connected to one another, for example, as is known from the prior art, they are with each other glued.
  • the thread guide tube 1 of Figure 1 has in the region of the first section 11 and the second section 12 each have a coupling element 3.
  • the two parts of the coupling element 3 work together, so that the first section 11 and the second section 12 of the thread guide tube 1 can be firmly but releasably connected.
  • the coupling element 3 is similar in the area of the first section 11 an external thread 31 is formed, while the part of the coupling element 3, which is connected to the second section 12, similar to one Internal thread 32 is formed.
  • the thread of the coupling element 3 is designed as a two-start thread with a pitch at which only a rotation of less than 90 ° is required to move the two parts of the Separate thread guide tube 1 from each other or with the help of the coupling element 3 to connect.
  • the thread works like a bayonet lock. Between the two parts (31, 32) of the coupling element 3 there is advantageously a seal 33 so that the coupling element 3 or its thread cannot get dirty. That dirt or dust is through the thread running in channel 10 into the interior of the thread guide tube 1 introduced and consists essentially of dust and fiber abrasion.
  • the separation point 4 of the thread guide tube 1 is designed such that the first section 11 and the second section 12 partially overlap.
  • the first section 11 is provided with an inner diameter that he can take part 41 of the second section 12.
  • the outer diameter of the part 41 of the second section 12 is so large that it lies close to the inside diameter of the first section 11.
  • the part of the first section 11 which is the part 41 of the second section 12 thus forms a guide for the second section 12 at the same time, which ensures that no offset occurs in channel 10, but the two parts can always be joined axially parallel, so that the running of the thread in the channel 10 is not disturbed by the separation point 4.
  • the separation point 4 is designed with its coupling element 3 so that the External thread is arranged on the second section 12, while the internal thread is formed on the first section 11. But it is equally possible that the arrangement of the threads is exactly the opposite. Corresponding it is then also possible that the second section 12 in the area the separation point 4 comprises the first section 11 and thus in its interior records.
  • the embodiment as shown in Figure 1 is advantageous chosen because the second section 12 thereby better grips and can be dismantled from the first section 11. The first section 11 can then remain in the area of the thread formation zone during disassembly.
  • the sheath 34 of the internal thread 32 offers through its larger Diameter a better contact surface for the hands of maintenance personnel or tools for removing the second section 12 from the first section 11 of the thread guide tube 1.
  • the thread guide tube 1 is in the area of the second section 12 designed as a straight, tubular component that on his End 121 of the second section has a ceramic insert 122, which in for example, the tube is glued in or just clipped on.
  • This ceramic insert 122 forms a wear protection for the end 121 of the second Section 12 of the thread guide tube 1.
  • the second section 12 running thread (not shown) otherwise causes no wear.
  • in the Area of the end of the second opposite the ceramic insert Section 12 advantageously has a channel 10 with a larger one Inner diameter, so that from the first section 11 into the second Section 12 incoming thread does not touch the second section 12.
  • the Channel 10 of the second section 12 has at the opposite end 122 Part of practically a kind of insertion funnel so that the thread run is not disturbed in the transition area at the separation point 4. Thereby is advantageously also avoided that wear in the channel 10 of the second section 12 arises from the running of the thread.
  • first section 11 and second section 12 via a coupling element in the form of threads is formed are connected to each other, it is just as possible the both e.g. to be attached to each other by means of a clip connection. About that it is also possible to use the two parts over one or more Connect screws together.
  • Figure 2 shows a thread guide tube designed according to the invention, similar that of Figure 1, with a sensor 7, the thread guide tube 1 in Area of the second section 12 is arranged.
  • the thread guide tube of Figure 2 otherwise also consists of a first section 11, the in turn consists of several individual parts, which together form one part are connected.
  • Bushing is the thread guide tube in a bore (not shown) of a receptacle, which holds the thread guide tube on the spinning machine. By suitable means, this recording is made during operation fixed.
  • Immediately to the socket 110 is, for example, at one Rotor spinning machine arranged a thread take-off nozzle, the thread from leads the spinning rotor out into the thread guide tube 1.
  • Bush 110 then runs the thread in channel 10 through the thread guide tube 1 through.
  • the thread runs after the thread guide tube mostly free until it is finally wound onto a spool.
  • the thread guide tube guaranteed by Figure 2 by his invention Design that the sensor 7, for checking and monitoring the thread is used, practically in the immediate vicinity of the thread formation zone, for example the rotor of an open-end rotor spinning machine, can be arranged. While the thread is still in the thread guide tube 1 is located, it is measured by sensor 7.
  • the socket 110 are by the The design of the sensor 7 or its presence is generally not impaired, since the thread guide tube 1 of Figure 2 according to the invention a separation point is formed so that the thread guide tube is divisible and so that the different sections of the thread guide tube 1 independently are separate from one another and thus also independent of one another can be.
  • the second section 12 of the thread guide tube 1 is in contrast to designed in Figure 1 so that the sensor element of the Sensor 7 also the thread passing through the thread guide tube can capture.
  • the second section 12 has an opening provided, into which the sensor element of sensor 7 extend can, or the second section 12 is interrupted in the thread running direction and is replaced in the area of the interruption by the sensor 7. Then a corresponding tubular part is contained in the sensor 7, which the Thread leads and ensures that the sensor element of the sensor 7th reached the thread.
  • the sensor 7 then forms part of the second Section 12 of the thread guide tube 1.
  • the sensor 7 can also be designed in this way be that it forms the end 121 of the second section 12. Becomes the second section 12 divided by the sensor 7, the two sections of the second section 12 is firmly connected to the sensor 7 be, e.g. by gluing or they are by means of detachable connections with the Sensor 7 connected.
  • the sensor 7 can for example be a sensor of the type that is suitable to recognize the presence of a thread in the thread guide tube 1. This is necessary to the spinning machine or the spinning station when it occurs by controlling thread breakage accordingly.
  • the Sensor 7 can also be designed such that it is suitable for the quality of the produced Monitor thread.
  • the sensor is included Suitable means provided, the mass and / or the thickness of the thread can capture. This is done, for example, using capacitive measuring methods or by means of optical processes.
