Definitions

  • the present invention relates to a spinning machine, in particular ring spinning machine, with a plurality of juxtaposed spinning units, each spinning unit a drafting with an output cylinder for warping a fiber strand, a spinning device for rotating the warped sliver to a thread and arranged between the drafting and spinning device false twisting device has, wherein the false twist device at least one driven by a drive means belt and two opposing Riementrums which are substantially transverse to the thread and are looped by the thread Z- or S-shaped, having, and a corresponding false twist device.
  • a false twist device with two belts is provided.
  • the belts are arranged in a circle, wherein the thread is between the two belts, so they do not wrap around.
  • this arrangement is variable, but it is very complicated to implement on a spinning machine structurally.
  • the introduction of a uniform rotation in the thread can not be ensured by greatly different friction, which may be caused for example by variations in the thread thickness.
  • the drive device drives the belt wheels of one or more spinning units.
  • the false twist device is to be operated independently of the false twist devices of the other spinning stations. Thread wrapping of the belts during a yarn break thus has no influence on adjacent spinning stations. The spinning operation is thereby very reliable and operate with low yarn breaks. Also, an individual adjustment to different requirements of the false twist device for the respective threads is possible.
  • the drive device is provided for several spinning units. In this case, the spinning machine can be divided into individual groups, which include, for example, the spinning stations between two bearing punches or the spinning stations of a section. Even a limitation to a half of the machine still has certain advantages, since the fiber convolutions of the thread breaks solve in many cases by the very frequent deflection of the belt and thus row thread breaks are avoided.
  • the output cylinder of the drafting system (s) is used as drive shaft for driving the belt or the drive shaft is driven by means of the output cylinder.
  • the required in the drafting and driven drive shaft of the output cylinder is thus used in a simple way to drive the belt.
  • the drive shaft is assigned to all spinning units on one side of the spinning machine or the spinning units of a section or the spinning units of a punching field or only a single spinning unit, it is possible to form groups for the drives which are individually adjustable. Also, the replacement of individual drive shafts or other parts of the false twist device in this way is very easy. For example, the operation of the unaffected spinning units can be continued while a defective spinning unit is being repaired.
  • the drive device has a drive belt for driving the belt spools of the false twist device, a large number of adjustments can be achieved by corresponding pulleys in a very simple manner.
  • the rotation can be picked up by a drive shaft further away from the false twisting belt and transferred to its false twisting belt.
  • the belts for the false twisting device can be relatively short, depending on the design, whereby the elasticity of the belts of the false twisting device is sufficient to tension the belt properly and on the other hand to be able to consistently introduce a false twist in the thread can.
  • the drive shaft or the drive pulley is arranged in the region of the drafting system, in particular below the drafting arrangement, a particularly compact design can be achieved.
  • the drive of the false twist device can be particularly advantageous here, since the motors for driving the drive shaft and the drive pulley can be accommodated particularly advantageous in this area.
  • the beltrems are guided around the drive shaft or the drive pulley and about a front roller.
  • the front roller deflects the belt and guides it back to the drive shaft. Due to the design with drive shaft or drive pulley and front roller a very compact and very simple construction is achieved.
  • the false twist device can hereby very easily be arranged largely parallel to the drafting arrangement between the drafting arrangement and the spinning device.
  • the front roller is rotatably supported by means of a substantially vertically arranged axis.
  • the front roller is thus largely horizontal in the spinning unit.
  • this design leads to a very simple and inexpensive construction, which also makes the maintenance of the false twisting very easy.
  • the axis of the front roller is preferably pivotally mounted.
  • the front roller is arranged on a holder provided for one or two adjacent spinning units.
  • Ring spinning machines are very often designed so that two adjacent spinning stations have two interconnected drafting. This also results in a corresponding advantage, even if the two front roller are attached to a common holder.
  • a single belt is provided for one or more spinning units.
  • the belt is deflected in such a way that in each spinning unit two opposing Riementrums can be brought to act on the thread.
  • a false twist device with at least one belt and a drive device, in which the belt is driven in the manner described above, in particular substantially parallel to the yarn path and perpendicular to the output roller of the drafting system, is also part of the present invention.
  • the thread depending on the running direction of the belt seen from the front in S- or in Z- Direction through the straps are performed. It is particularly advantageous if two belts are provided and there is a gap between the front rollers. This is compared to the prior art, the threading of the thread replaced by a passage of the thread and the piecing process is much easier.
  • the belt of the false twist device for twisting the thread is preferably an endless round belt. It has been found that a belt that runs from one spinning station to the other along the machine can result in a series thread breakage. According to an advantageous embodiment, it is therefore proposed that an endless belt per spinning station is used for the false twist device. If one leads the belt so as in the prior art that the swirl zone in which the thread is twisted parallel to the machine runs, do not bring the units in the Spinnstellenenander so that then from one belt to the other belt Neighbor spinning station is sufficient distance, which is a prerequisite to avoid row thread breaks. Therefore, it is invented Proposed according to the invention, the belt or belts run in the area of the false-wire zone transversely to the machine.
  • the belt is a wearing part as the thread rubs continuously on the belt. It is therefore advantageous if it can be easily replaced. If the drive belt driven by a shaft with traction sheaves, so he is trapped. The shaft must therefore be removed during drive belt replacement, so that it can be threaded off and threaded onto the shaft. The expansion of the shaft should be easy to carry out. It is therefore advantageous if the shaft is not too long and best extends only over a punching field.
  • two belts are advantageously used, in which the front roller is taken from above and from below or from one side and the other via holders. This creates a space between the two front rollers through which the thread can be made during piecing. Further advantages of the invention are described in the following exemplary embodiments.
