  • a sliver is spun in a flyer to a roving and the roving guided over hanging on the ceiling transport rails to the individual jobs of a ring spinning machine.
  • the roving is then drawn in a drafting of the ring spinning machine and spun by the movement of the circulating on the ring runner through which the stretched roving is guided, spun into yarn.
  • the movement of the rotor on the ring is in this case induced by rotation of a seated on a spindle sleeve on which the yarn is wound.
  • the ring on which the rotor runs can not be made arbitrarily large, so that the diameter of the cop, which is generated when winding the yarn on the sleeve, is limited. This also continues to result in a limited amount of yarn on the sleeve. Once the maximum amount of yarn has been generated and the cop finished, this is removed with a customer, the so-called "doffer", and used an empty sleeve.

  • the expression “that the spindles are suspended” means that the spindles are at the top and the free end of the spindles points downwards in the direction of the ground, whereas the term “spindles” means that the spindles are picked up is down and the free end of the spindles points upwards.
  • the sleeves for exchanging that is to remove the cop and for inserting an empty sleeve to turn up, so that these can be easily removed upwards.
  • This has the particular advantage that the replacement of the sleeves can be done automatically in a short time and also in the manner known for conventional ring machines with standing spindles.
  • the spindle bank is preferably mounted displaceable vertically so that the horizontal axis is higher when the spindle is suspended than when the spindle is turned upwards.
  • the required yarn reserve it is also possible to provide the required yarn reserve by, for example, before the spindle spindle is rotated by all the spindles of the spindle bank, some yarn is unwound again. The provision of the yarn reserve is required because the yarn clamped to the spindle partially wound around the ring rail during rotation of the spindle bank and the associated pivoting of the spindle.
  • a pickup is arranged above the spindle bank, with which the sleeves can be removed from the spindle or inserted onto the spindle.

Due to the inventive ability to bring the sleeves for removal and insertion in an upright position, it is possible to customers, generally called Doffer, use, which correspond to those used for presently usual ring spinning machines with standing spindle.
  • a transport system for the sleeves is arranged parallel to the spindle bank. This makes it possible to insert empty sleeves into the transport system on one side from a central feed point, to guide them along the ring spinning machine to the respective spinning stations and to guide the cops through the transport system after the replacement of the sleeves to a central removal point and remove them there , The cops are then processed in the usual way and rewound in a winder on a larger coil.

Furthermore, the transport system is preferably arranged so that the transported with the transport system sleeves are positioned above the hanging spindles. For a quick replacement of the sleeves, the transport system is further preferably designed so that the sleeves are conveyed standing in the transport system.

  • the rings of the ring rail enclose the spindles during the spinning process, it is furthermore necessary to either rotate the ring rail for rotating the spindle rail or, alternatively and preferably, also to move it out of the pivot range of the spindle rail.
  • the ring rail is preferably vertically displaced so far that the ring rail can be guided to a position below the spindle with the sleeve seated thereon to allow the spindle spindle to rotate.
  • the vertical movement of the ring rail from the range of rotation of the spindle bank allows a simpler construction than would be necessary if the ring rail is rotated with the spindle bank.
  • the yarn is preferably kept under a gentle tension.
  • a yarn tensioner is preferably positioned above the drafting system. If, as usual, a yarn guide and a balloon ring are used, the yarn tensioner is preferably positioned above the drafting system and below the yarn guide and balloon ring. So that yarn guide, balloon ring and ring rail can be moved out of the swivel range of the spindle rail, it may be necessary to make the yarn tensioner also displaceable. Alternatively, it is also possible to position the yarn tensioner so that it does not interfere with the movement of yarn guide, balloon ring and ring rail without being moved.
  • the ring spinning machine comprises a plurality of sections, each section each comprising a plurality of drafting devices and spinning devices. Since each spinning device is associated with a drafting system, the number of drafting and spinning devices of a section is identical. The total number of drafting devices and spinning devices is preferably a multiple of the number of rows of slivers for sliver storage, which are positioned below the drafting units. Thus, if it is intended to provide three cans per row, the number of drafting and spinning devices of a section is a multiple of three. Usually one section comprises 24 or 48 spinning stations.
  • the individual sections are each separated by carriers for the ring spinning machine.
  • the number of drafting and spinning devices is thus dependent on the number of parallel rows of cans, in addition to how many cans can be positioned next to each other between two carriers.
  • the carriers on which the spinning machine stands can have any desired shape known to those skilled in the art. For example, it is possible to provide portals or a central support in the middle.
  • the individual spindles of the ring spinning machine can in principle be driven by a central drive as in conventional ring spinning machines. However, it is preferred to drive each spindle with its own drive, in particular a synchronous motor.
  • a synchronous motor on the one hand has the advantage that yarn faults that can occur due to non-uniform movement, for example due to jerking of a very long shaft, are avoided.
  • the use of synchronous motors allows a consistent and uniform yarn quality on all spindles.
  • the synchronous motors of the individual spindles are preferably controlled synchronously by a central control unit.
  • the central control unit is preferably located at one end of the ring spinning machine.
  • the affected spindle is braked, thereby falls out of the synchronous speed and comes to a stop.
  • the brakes already in use can be used to brake the spindle.
  • the spindle After correcting the error, the spindle should be brought back to the speed required for production as quickly as possible.
  • special motors which allow the restarting up to the synchronous speed.
  • this requires individual software and hardware for each spindle.
  • a pneumatically operated turbine is included in order to bring the spindle back to the speed required for the production as quickly as possible. With the pneumatically operated turbine, the spindle can be brought to the required speed very quickly and then operated with the centrally controlled synchronous motor.
  • the ring rail comprises a fuse with which the rotor can be fixed.
  • a fuse with which the rotor can be fixed.
  • This has the advantage that the rotor is held in its position when the machine is at a standstill, and secondly, with the retaining ring an opening in the rotor, which is necessary due to the geometric configuration of the ring, can pass through the holder for the ring can, can be closed.
  • a fuse can be, for example, an axially displaceable locking ring, which does not touch the rotor in a first position, so that it can move freely and rests in a second position on the rotor.
  • the fuse may be an elastic sleeve, for example.
  • a sliver guide with a clamp for the sliver that can be displaced vertically by at least one stack length is positioned below the drafting system.
  • the ring spinning machine is stopped.
  • the remaining sliver is held with the clamp and the clamp is moved vertically downwards by at least one staple length.
  • the sliver tears between the drafting and the clamp, so that remains in the stationary drafting a residue of the sliver and forms a tuft.
  • the new sliver is clamped in the clamp of Lunten Unit, the clamp is moved up until the remaining in the drafting tuft and the new sliver come into contact with each other. Subsequently, the clamp is moved further upwards at a speed which corresponds to the circumferential speed of the input rollers of the drafting system. As a result, the new sliver connects to the tuft and it is produced a continuous sliver, so that it is possible to perform the lot change without an opening of the drafting. It is not necessary to re-thread the sliver after the batch change.
  • a method of operating a ring spinning machine comprises the following steps: (a) inserting a sleeve onto a spindle and rotating the spindle bench so that the spindle hangs in the spindle bench after rotation, (b) moving the ring rail upwards, so that the rings enclose the spindles and, if present, shifting the thread guides and the balloon rings to the position required for the operation of the ring spinning machine,
  • the steps (a), (b) and (e) are respectively performed when cops having the maximum possible thread amount have been produced. Since it is then not possible to produce more yarn, it is necessary to swap the sleeves. For this purpose, the cops are removed from the spindle and empty sleeves are used. Subsequently, yarn can then be further generated. This process can be repeated until the supply of sliver is exhausted below the drafting equipment. As soon as the supply of sliver is used up, that is, a game change is necessary, the sliver is held in the terminal of the Lunten Adjust and moved the clamp down so that the sliver tears between drafting and clamp for the lot change. Since the individual fibers of the sliver are shifted against each other when moving the clamp, it is necessary that the clamp is displaceable by at least one staple length. This ensures that not individual fibers of the sliver still hang together.
  • the clamp After moving the clamp down, it is possible to remove the empty cans or the only remains of sliver containing cans and swap through fiber sliver filled cans. For this purpose, first the clamp is opened, so that the remains of sliver fall into the empty cans. After removal of the empty cans or the only remains of sliver containing cans are filled with sliver cans positioned under the ring spinning machine. The fresh sliver is then clamped in the clamp of the sliver guide. Subsequently, the clamp is moved back up against a hanging in the input rollers of the drafting tuft.
  • the sliver is not presented in cans, but in other ways, it is of course also possible to track according to either other reservoir or sliver without reservoir.
  • the use of cans has the advantage that the replacement can be automated. Since the content in all cans is generally the same, all cans on one side of a ring spinning machine are usually emptied at the same time. Residues of sliver that remain in the cans can then be recycled to new sliver and further processed.
  • the spindle bank is moved upwards, when the spindles are brought from the standing to the hanging position and down, when the spindles are brought from the hanging to the standing position.
  • some yarn can be unwound from the sleeve again to provide the yarn reserve.
  • the necessary to change the sleeves rotating and vertical displacement of the spindle bank can be done either simultaneously or it is possible to move the spindle first recording vertically and then rotate when the spindle from the hanging in the standing position and accordingly first to rotate and then to move vertically when the spindle is to be moved from the standing to the hanging position. By this appropriate movement is avoided that an excessive tension on the yarn acts.
  • the ring spinning machine according to the invention is preferably designed so that each spindle can be stopped individually. That means that at Detection of a thread break the corresponding spindle is stopped.
  • the detection of a thread breakage can be done by the usual methods already used for ring spinning machines today.
