Definitions

  • the invention relates to a method for operating an automatic winding machine according to the preamble of the first claim.
  • Automatic winding machines also have an automatic bobbin and tube transport system, which can have several transport loops for bobbins and tubes. In many cases, such transport systems also have a direct connection to the transport system of the spinning machine, with copes and sleeves being exchanged at the interface.
  • Such a transport system is known for example from DE 39 19 542 A1. However, this document does not show how to proceed when changing lots.
  • the object of the invention is to provide a method for operating an automatic winding machine which can be used when changing lots.
  • the Solution according to the invention allows the sleeves to be stored without requiring additional storage capacity.
  • empty cores are exchanged for fresh cops between a transport path of the spinning machine and the neighboring transport path of the winding machine, this process is ended when no fresh cops arrive from the spinning machine after the batch has ended. For this reason, empty sleeves should no longer be fed to this transport route.
  • Such a path which runs around the end of the winding machine, is described for example in the generic DE 39 19 542 A1. It is also advantageous to transport the cops and sleeves vertically on Caddy's arbors, which rest on conveyor belts, from which they are carried by friction. The caddy's are managed within transport channels. Such transport systems have long been known, for example from JP-A 52-25 139.
  • the associated Drawing shows a transport system of a winding machine, which was divided into partial figures 1a and 1b for reasons of space.
  • the winding machine 1 has a bobbin and tube transport system with several transport loops, some of which have common transport paths. Caddy's 4, which carry cops or sleeves, are transported on these transport routes. The depiction of the cops or sleeves has been omitted for reasons of clarity.
  • a feed path 2 for feeding the cops to the winding stations extends along the entire winding machine 1.
  • Preparation lines 25 branch off from the feed path 2 and lead through preparation stations 26 to 28. These preparation stations 25 to 28 can be used to prepare the cops step by step in a known manner, as is described, for example, in DE 39 19 542 A1.
  • a distribution section 24 is provided which alternatively feeds the cops to a so-called reversing belt 3 or again to the feed path 2. This distribution section 24 is controlled by the last preparation station 28, which checks the success of the cop preparation. If the cop is successfully prepared, the distribution section 24, which can also consist of a reversing belt, feeds it to the reversing belt 3.
  • the caddy 4 carrying it is fed to the feed path 2, which either leads it to the next preparation path 25 or around the end of the winding machine 1 via the diversion path 31 to the return belt 22.
  • This return belt 22 also runs parallel to the feed belt 2 along the entire winding machine. The distribution of the cops on the different preparation lines 25 is also described in DE 39 19 542 A1, which is why there is no need to go into this here.
  • the reversing belt 3 is switched in its transport direction at predeterminable time intervals and distributes the supplied cops to the transport paths 21 leading through the winding stations 5. Between the winding station 5, that is to say the unwinding position of the respective cop, and the reversing belt 3 there are still two reserve positions 6 for them the bobbins wearing Caddy 4. On the reversing belt 3, groups 7 of Caddy's patrol with cops, which then enter a transport path 21 leading through the winding stations when the rearmost reserve position 6 is not occupied. Details on this can also be found in DE 39 19 542 A1. It should also be pointed out that only a small part of the circulating Caddy's 4 has been shown for reasons of clarity. In particular, the transport tracks 21 would have to be occupied with three caddies in most cases, as is demonstrated on a transport track 21.
  • the remaining cop 9 is a so-called residual cop, which still carries a quantity of remaining thread that can be processed.
  • This residual cop 9 is located next to a residual thread detector 33, which detects the thread quantity still present.
  • This residual thread detector controls an electromagnet 11, which acts on an iron ring present on the caddy's 4 and deflects the caddy from the return belt 22 onto the secondary transport path 12.
  • the remaining cop 9 arrives at a cone preparation device 15, which searches for the thread start on the cop cone regardless of its position and deposits it again in such a way that it can be detected at the winding point.
  • a cop prepared in this way is then fed back to the feed path 2 via the connecting section 16.
  • the cone preparation device 15 also has one Detector that checks the preparation success. If the remaining cop 9 could not be successfully prepared, it arrives on the feed path 17 to a storage section 18.
  • a sleeve 8 transported past next to an end frame 19 with a small amount of remaining thread is likewise identified as such by the remaining thread detector 33 and the caddy 4 carrying it is redirected by the electromagnet 11 into the secondary transport path 12.
  • this sleeve 8 is immediately branched off again and arrives at a sleeve cleaning device 10.
  • An electromagnet can also be arranged at this branch, which is additionally controlled by the residual thread detector 33. A representation has been omitted for reasons of space.
  • the cleaned sleeve 8 then returns to the return path 20 or, after unsuccessful cleaning, into the storage path 18 (see also DE 39 19 542 A1).
  • a completely empty spool 36 ejected from a winding unit 5 is also fed to the residual thread detector 33 on the return path 22, which does not switch on the electromagnet 11 in normal winding operation, so that the caddy carrying the empty tube 36 arrives on the transport path 13, against which the empty tube counteracts a fresh cop coming from the spinning machine is exchanged.
  • This cop then returns to the feed path 2 and, in the manner described, to its unwinding position in the winding machine.
  • sensors 29 are arranged, which detect incoming empty tubes 36 and open an adjacent switch 30 in order to enable the caddy 4 carrying the empty tube 36 to be transported further on the feed path 2. This ensures that the empty tubes remain on the transport routes intended for them.
  • the switches 30 are also provided for distributing the cops over the preparation lines 25 during normal operation of the winding machine. If, for example, as shown in the drawing, there are two preparation sections 25, the switch 30 arranged on the first branch in the feed direction of the cops would alternately pass every second cop. It is of course also possible to switch over after two or more cops. Another possibility is that when the distance between the feed path and the first preparation station 26 is filled, the next arriving cop or the caddy 4 carrying it is deflected by the outer edge of the last caddy and transported on the feed path 2 to the next preparation path 25.
  • the path of the empty tubes is indicated by arrows 23, 32, 34 and 35. This transport route is long enough to accommodate all empty tubes 36, since the number of caddies 4 in Transport system is constant. In this way, an additional memory for the intermediate storage of the empty tubes 36 can be saved until the end of the batch change.
