It is particularly preferred if the ring spinning machine is constructed so that it comprises at least one drafting device and at least one spinning device with a ring rail with at least one ring and on each ring a revolving runner and a spindle bank with at least one spindle, wherein the reservoir for sliver can be positioned below the drafting so that each drafting a sliver from below can be fed, and the ring rail is positioned above the drafting and each ring of the ring rail during operation of the ring spinning machine encloses a spindle with sleeve received thereon, the spindle hanging in the Recording is recorded for the spindle, so that the sliver is guided from bottom to top through the ring spinning machine.
  • the ring spinning machine By constructing the ring spinning machine with spindles suspended in spinning operation, it is possible to supply the sliver directly from below and in this way to keep the paths between the individual units, namely storage tank, drafting system and spinning station, as short as possible. This can prevent unwanted and uneven stretching of the sliver, which would lead to a non-uniform yarn.
  • Another advantage of the structure of the ring spinning machine with hanging spindles, where the sliver is fed from below, is that it can be dispensed with the otherwise necessary flyers. This waiver of the flyer has the further advantage that without additional space requirements, the transport device according to the invention for supplying the storage container can be used. The space required for the transversal guidance was occupied with previously necessary systems with ring spinning machines with the necessary flyers.
  • transport units are used from several individual units.
  • the space required for the flyers corresponds to one third of the length of a ring spinning machine, so that a transport unit in this case is preferably divided into three individual units.

  • 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. In order to enable the quickest possible replacement of the sleeves, it is preferred if the replacement can be automated.
  • a pickup is arranged above the spindle bank, with which the sleeves can be removed from the spindles of the spindle bank or inserted onto the spindles of the spindle bank.

  • the yarn guide and the balloon ring are vertically displaceable. This allows the yarn guide and the balloon ring to be moved downwards, thus freeing the spindle pivoting range.
  • the ring rail encloses the sleeve on the spindle during the spinning process, it is furthermore necessary, for rotating the spindle bank, to either rotate the ring rail or alternatively and preferably also to displace it.
  • the ring rail is preferably vertically displaced so far that the ring rail can be guided to a position below the spindle, so that the rotation of the spindle rail is made possible.
  • the vertical displacement of the ring rail from the rotation range of the spindle bank allowed 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.
  • the individual sections are preferably separated in each case by carriers for the ring spinning machine.

  • the use of synchronous motors allows a consistent and uniform yarn quality at all spinning positions.
  • 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. Should there be a thread break at a spinning station, the affected spindle is braked, thereby falls out of the synchronous speed and comes to a stop.

  • 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 Entry, 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.

  • the ring spinning machines are usually symmetrical and have up to 1824 spinning positions. With 20 such ring spinning machines, a throughput of 400 to 500 kg / h is possible.
  • a lateral guide for a Transport unit assigned to provide the spinning stations with sliver. In this way, in symmetrically constructed ring spinning machines both sides can be equipped independently with sliver.
  • the storage containers used for the presentation of the sliver are, especially when used with ring spinning machines usual 9-inch cans with a capacity of 4 to 5 kg sliver. Such a supply is generally sufficient for a service life of up to 250h. This means that a replacement of the reservoir only every 10 days is required. Due to the long term is a translation stage 12 for the replacement of the reservoir even with the use of 20 spinning machines 1 with two rows of spinning stations, that is a total of 40 rows and thus 40 lateral guides are driven into the transport units with storage tanks, sufficient. It can all necessary movements for a lot change, that is an exchange of the reservoir with only one transverse stage 12 are executed.

  • the transport unit is divided into three individual units 3.0.2 as shown in FIG. 5c.
  • the transport unit includes the transversal platform 12 six lanes for the individual units, so that transport units with cans with sliver and with empty cans for a spin web can be placed simultaneously on the transverse stage 12.
  • the advantage of such a division of the transport unit into three individual units 3.0.2 is that in this case the space required for the working area 15 of the transverse stage corresponds to the workstation that is used in conventional ring spinning machines that work with upright spindles and roving from a flyer for which flyers are needed.
  • a central control not shown here, is preferably provided, which controls all transport paths, times, etc. depending on the requirements of the spinning process.

Abstract

L'invention concerne un dispositif de transport de récipients de stockage (2) d'une bande de fibres (2.1) vers des postes de filage d'un métier à filer (1) agencés en série, le dispositif comprenant : une unité de transport (3) munie de rouleaux (3.2) et d'un mécanisme d'entraînement (3.3), ainsi que d'une surface de support sur laquelle les récipients de stockage (2) sont mis en place, un poste d'équipement où les récipients de stockage pleins (2.1) sont mis en place sur la surface de support et les récipients de stockage vides (2.2) sont retirés de la surface de support, et au moins un dispositif de guidage transversal (10) et au moins un dispositif de guidage latéral (11) le long desquels l'unité de transport (3) est déplacée, les dispositifs de guidage latéral (11) étant orientés parallèlement à l'orientation du métier à filer (1) et les dispositifs de guidage transversal (10) étant orientés transversalement à l'orientation du métier à filer (1). L'invention concerne par ailleurs un dispositif de production de fils muni dudit dispositif de transport.
