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 spinning machine in which a false twisting device is arranged between a drafting device, on which the sliver is warped and a coil, on which the sliver is wound up.
  • the false twist device consists of a single belt, which is driven by a drive device and runs essentially outside the spinning machine along its longitudinal side. Upper and lower run of the belt are driven in opposite directions. The yarn contacts the two Riementrums punctiform (Figure 4), when the belts are arranged directly next to each other.
  • the straps are spaced apart and extend substantially vertically one above the other in the opposite direction.
  • the false twisting device is formed from a single belt.
  • the two Riementrums have the same amount of speed, but they are running in the opposite direction. In this case, it is disadvantageous that when the belt is wound around by thread residues during a thread break, this reversal denden thread remnants are transported to adjacent spinning stations and there also cause a yarn breakage.
  • 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.
  • a false twist device is shown, which is associated with a texturing device.
  • a thread is treated during the rewinding from a first reel to a second reel in the texturing device by means of heat, a rotation of the yarn is fixed in a heating chamber. Spinning a yarn does not take place in this facility.
  • the false twist is created by means of two parallel belts over which the yarn is laid and wraps around it. The belts have different speeds and are driven by means of another belt and a drive shaft extending along the whole machine.
  • the false-twist belts are tensioned by means of a spring device which presses the two pulleys for the belts into a tensioning position.
  • a disadvantage of this prior art is that the adjustment of the correct speed of the false twisting belt is difficult and also no suggestion for use in a spinning machine is made.
  • Object of the present invention is to provide a false twist device, which is suitable for spinning operation and yarn breaks, in particular adjacent spinning stations, avoids.
  • the object is solved with the features of the independent claims.
  • a spinning machine in particular ring spinning machine, has a plurality of juxtaposed spinning units.
  • Each spinning unit is equipped with a drafting system with an output cylinder for warping a fiber strand.
  • each spinning unit has a spinning device for rotating the warped sliver to a thread and arranged between the drafting and the spinning device false twist device.
  • the false twisting device has at least one driven by a drive device belt with two opposing Riementrums that are substantially transverse to the thread and are wrapped by the thread z-shaped.
  • the main direction of the beltrums in particular in the region of the Z-shaped loop, that is to say the orientation or the essential orientation of the beltroms, runs essentially transversely to the axis of the output cylinder.
  • the Riementrums are largely the same orientation in plan view of the spinning device with the direction of the thread.
  • An angular deviation from the running direction of the thread may be present in the range of up to about 30 degrees due to the arrangement of the diverting rollers for the beltroms.
  • the false twist device can be carried out largely independently of adjacent spinning stations.
  • a looping of a Riementrums by a broken thread thus does not readily lead to a Erasmusnfadenbruch, since the Riementrum is assigned in advantageous embodiments only one or a few spinning stations and beyond a certain self-cleaning is achieved by the regular deflections.
  • the belt runs transversely to the longitudinal direction of the machine, at least in the area of the thread loop. Since the belt is elastic, it can be placed on belt pulleys with a certain preload. That's enough strained to evenly applied to the thread and to twist it in the appropriate direction.
  • 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.
  • each spinning unit has its own false twisting device independent of other spinning units with two endless belts spaced apart from each other, a very effective and easy to maintain false twisting device can be provided.

  • the exchange can be done very quickly.
  • the threading of the thread during piecing can also take place via the deflection rollers or a front roller, which substantially improves the handling of the false twist device.
  • the belt can be driven via this drive shaft or drive disk. This is advantageously a particularly simple drive of the belt, as can be dispensed with in many cases on a large number of pulleys and drives.
  • the drive shaft or the drive pulley is driven by a drive belt or drive gear.
  • the drive belt is mounted so that it is simple, i. can be replaced with as little or no assembly of other components. The same applies to the drive gear.
  • 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 belt wraps around the drive shaft or the drive disk or if the drive belt is pressed onto the drive shaft or drive disk by means of a pressure roller, a particularly advantageous tension of the drive belt is achieved, so that irregularities in the introduction of the false twist are largely avoided.
  • the axial guide may for example be a groove in the drive shaft or the drive pulley.
  • the guide ensures that the belt rotates positionally accurate. If the belt of the false twisting device is pressed onto the drive shaft or the drive pulley by means of a pressure roller or if the belt wraps around the drive shaft or the drive pulley, a particularly advantageous and slip-free guidance of the belt of the false twist device is ensured here as well.
  • 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 arranged on the side facing away from the drafting of the threadline, in particular above the spinning device.
  • the front roller is thus, so to speak, outside the actual ring spinning machine.
  • the thread runs between the front roller of the drive device and wraps around there the Z-shaped belt rums.
  • the arrangement of the front roller above the spinning unit, the belt guide can be done in a range which is not annoying or even particularly advantageous for the operation of the spinning unit, since it can be easily reached by an operator to insert the thread in the false twist device set.
  • 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 particularly advantageous holder is open, ie formed with cantilevered deflection rollers or front roller / s.
  • the belt can be easily replaced, ie without disassembly of other components. If two front rollers for two belts of the false twisting device of a single spinning unit are arranged on the holder in such a way that there is a free space between the two front rollers through which the belts can be threaded out and / or the yarn can be inserted during piecing also easy to carry out the handling of the false twist device.

  • the belt is deflected in such a way that in each spinning unit two opposing Riementrums can be brought to act on the thread.

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.
  • the drive of the shaft can be done via a single motor or via the output cylinder of the drafting system.
  • As transmission preferably serves a gear pair, so that the shaft can be easily disassembled. If a drive belt is provided, it should not be caught in the output cylinder. A drive belt directly to the engine may be more advantageous.
  • 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.
