Definitions

  • the invention presented relates to a process for constituting spools, particularly spools carrying yarn of the type used on weaving machines, but also and more generally, any spool carrying a thread made of any material and intended for any subsector of the textile industry.
  • the invention also relates to a method and a device for searching for thread, making it possible to search for the beginning and the end of the thread on the coils mentioned above.
  • the invention presented provides for the constitution of a coil systematically excluding the drawback that has just been mentioned. In other words, it offers a coil which is particularly suitable for the automatic search for the beginning and the end of the thread.
  • the invention consists in a method for constituting coils, comprising the winding of a quantity of wire in the form of a coil, characterized in that, after winding, the beginning and the end of the wire of said coil are connected to each other in such a way that the wire thus connected forms a loop of wire which can be grasped.
  • the beginning and the end of the thread will be linked by knotting.
  • a loop is thus obtained which can be detected and entered relatively simply by an automatic device, to then be cut, after which the beginning and the end of the wire obtained in this way can be brought to the points required by the operation of the machine. .
  • the invention presented also relates to a method and a device for searching for the wire intended in particular to search, according to an automatic procedure, the beginning and the end of the coil wire conforming to the definition above.
  • a coil 1 according to the invention mainly consists of a quantity of wire 3 laid on a bobbin 2, the beginning 4 and the end 5 of the wire being connected, for example, by means of a node 6. In this way, a loop 7 is formed which is easier to find than two free ends.
  • the loop 7 extends along the outer turns of the coil 1, between the opposite ends 8 and 9.
  • the loop 7 can of course be carried out along a different path and pass for example from inside the bobbin 2 as in the embodiment illustrated in FIG. 2.
  • the search for the loop 7 mentioned above can be carried out in a simple manner using, for example, a search device conforming to that illustrated in FIG. 3.
  • This device mainly consists of a vacuum nozzle 10 which must cover at least partially the length L of the coil 1.
  • the loop 7 will be sucked over a certain distance by the nozzle .
  • devices 11 and 12 consisting for example of hooks, can remove from the end piece the start 4 and the end 5 of the wire which will then be cut, the two ends then being brought to the points required by the operation of the machine. weave.
  • the beginning and the end of the wire obtained by cutting the loop do not necessarily correspond to the beginning 4 and to the end 5 of the wire when the reel is wound up.
  • the end 5 of the thread of a conventional spool is generally too short to be brought to the point required by the operation of the weaving machine.
  • the sectioning point it will suffice to choose the sectioning point suitably on the loop 7 - the only constraint being that this sectioning point must not correspond to the knotting point - to always obtain a end of thread or start of thread of the appropriate length.
  • FIG. 4 represents a reel holder allowing an automatic positioning of the reels 1 mentioned above in order to ensure, for example, an automatic supply of thread 13 intended for weft insertions on a weaving machine.
  • the reels 1 are brought to a conveyor 14 and placed on the belt 15 of the reel holder.
  • the aforementioned loop 7 can be searched for example using a wire search device similar to that described above, then sectioned, following which the beginning 4 and the end 5 of the thread are brought into the clamping devices 16 and 17.
  • One of these ends will then be knotted at the end of the thread of the previous reel using the knotter 18 and l 'other, presented in such a way that the next coil can be tied there after a certain time. It is clear that this installation will have as many clamping devices 16, 17, 19 and 20 as there are places provided for the coils.
  • the pinching devices 16 and 17 will each comprise for example two wire clamps 21 and 22, mounted as illustrated in FIGS. 5 and 6.
  • the pinching of the wires will be carried out in such a way that the start 4 of the wire of a new coil will be presented overlapping with respect to the end 5 of the thread of the previous reel, after which the two threads will be knotted automatically as illustrated schematically the strapping 23. After the knotting, the ends of thread 24 and 25 will be cut as illustrated in Figure 7, so as to obtain a connection as smooth as possible.
  • connection of the ends mentioned above can also be carried out by a splice and not by knotting.
