Description

L'invention présentée a trait à un procédé pour constituer des bobines, particulièrement des bobines portant du filé du type de celles utilisées sur les machines à tisser, mais également et de façon plus générale, toute bobine portant un fil réalisé en une matière quelconque et destinée à tout sous-secteur de l'industrie textile.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.

L'invention a également trait à un procédé et un dispositif de recherche de fil, permettant la recherche du début et de la fin du fil sur les bobines évoquées ci-dessus.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.

On sait que les bobines, que l'on rencontre dans tous les sous-secteurs de l'industrie textile, sont envidées sur des bobinoirs et possèdent dès lors un début de fil relié au fil de l'enveloppe extérieure de la bobine.It is known that the bobbins, which are found in all the sub-sectors of the textile industry, are wound on bobbins and therefore have a start of thread connected to the thread of the outer casing of the bobbin.

Après leur fabrication, ces bobines sont acheminées vers les utilisateurs qui s'en serviront. Il est clair que pour placer convenablement les bobines sur une installation telle qu'une machine à tisser, ceux-ci devront repérer le début du fil. Sur une machine à tisser, il faudra en outre relier la fin du fil d'une bobine pratiquement vide au début du fil de la bobine suivante pour obtenir une alimentation en continu de la machine; dès lors, il faudra également localiser la fin du fil sur chaque bobine.After their manufacture, these coils are sent to the users who will use them. It is clear that to properly place the spools on an installation such as a weaving machine, they will have to identify the beginning of the thread. On a weaving machine, it will also be necessary to connect the end of the thread of a practically empty bobbin to the beginning of the thread of the following bobbin to obtain a continuous supply of the machine; therefore, it will also be necessary to locate the end of the wire on each reel.

Etant donné la taille relativement volumineuse des bobines, il est assez malaisé d'en détecter le début et la fin du fil. On sait qu'un des moyens classiquement mis en oeuvre pour simplifier la recherche du début ou de la fin du fil consiste à les munir d'une étiquette ou à les glisser dans le bobinot. Toutefois, cette solution ne se prête guère à la détection du début et de la fin du fil sur les installations automatiques.Given the relatively large size of the coils, it is quite difficult to detect the beginning and the end of the wire. It is known that one of the means conventionally used to simplify the search for the beginning or the end of the thread consists in providing them with a label or in sliding them into the bobbin. However, this solution hardly lends itself to detecting the start and end of the wire on automatic installations.

Du brevet US 3.352.504 il est connu que des bobines peuvent présenter des entrelacements accidentels entre le début et la fin du fil envidé. Le brevet US 3.352.504 offre une solution pour décrocher lesdits entrelacements.From US Pat. No. 3,352,504 it is known that coils can have accidental intertwining between the start and the end of the thread being threaded. US Patent 3,352,504 offers a solution for unhooking said interleaving.

L'invention présentée prévoit la constitution d'une bobine excluant systématiquement l'inconvénient que l'on vient d'évoquer. Elle propose en d'autres termes une bobine qui se prête particulièrement à la recherche automatique du début et de la fin du fil.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.

Pour cela, l'invention consiste dans un procédé pour constituer des bobines, comportant l'envidage d'une quantité de fil en forme de bobine, caractérisé en ce que, après envidage, le début et la fin du fil de ladite bobine sont reliés l'un à l'autre d'une telle manière que le fil ainsi relié forme une boucle de fil pouvant être saisie. De préférence, le début et la fin du fil seront reliés par nouage. On obtient ainsi une boucle qui peut être détectée et saisie de manière relativement simple par un dispositif automatique, pour être ensuite sectionnée, après quoi le début et la fin du fil obtenus de la sorte peuvent être amenés aux points requis par le fonctionnement de la machine.For this, 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. Preferably, 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. .

L'invention présentée a également trait à un procédé et un dispositif de recherche du fil destiné en particulier à rechercher selon une procédure automatique le début et la fin du fil de bobines conformes à la définition ci-dessus.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.

Afin de mieux mettre en lumière les caractéristiques de l'invention, on trouvera ci-après, en guise d'exemples sans caractère limitatif, la description de quelques formes d'exécution préférentielles de telles bobines, d'un dispositif de recherche de fil et d'un certain nombre de possibilités d'application des bobines définies ci-dessus, avec référence aux dessins annexés, où:

  • ― les figures 1 et 2 représentent des bobines conformes à l'invention;
  • ― la figure 3 représente un dispositif de recherche de fil applicable à des bobines conformes à l'invention;
  • ― la figure 4 représente un porte-bobine acceptant des bobines conformes à l'invention;
  • ― les figures 5 et 6 illustrent la mise en place de telles bobines sur le porte-bobine.
In order to better highlight the characteristics of the invention, hereinafter, as examples without limitation, the description of some preferred embodiments of such coils, of a wire finding device and of a number of possibilities of application of the coils defined above, with reference to the appended drawings, where:
  • - Figures 1 and 2 show coils according to the invention;
  • - Figure 3 shows a wire search device applicable to coils according to the invention;
  • - Figure 4 shows a reel holder accepting reels according to the invention;
  • - Figures 5 and 6 illustrate the establishment of such coils on the reel holder.

Comme indiqué à la figure 1, une bobine 1 conforme à l'invention se compose principalement d'une quantité de fil 3 envidée sur un bobinot 2, le début 4 et la fin 5 du fil étant reliés, par exemple, au moyen d'un noeud 6. De cette manière, on forme une boucle 7 qui est plus facile à rechercher que deux extrémités libres.As shown in Figure 1, 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.

Dans la forme d'exécution illustrée à la figure 1, la boucle 7 s'étend le long des spires extérieures de la bobine 1, entre les extrémités opposées 8 et 9. La boucle 7 peut bien entendu être menée selon un trajet différent et passer par exemple par l'intérieur du bobinot 2 comme dans la forme d'exécution illustrée à la figure 2.In the embodiment illustrated in Figure 1, 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.

La recherche de la boucle 7 évoquée ci-dessus peut être réalisée de manière simple à l'aide, par exemple, d'un dispositif de recherche conforme à celui illustré à la figure 3. Ce dispositif se compose principalement d'un embout aspirateur 10 qui doit couvrir au moins partiellement la longueur L de la bobine 1. Lorsqu'une bobine 1 est présentée sous l'embout aspirateur 10 et qu'on lui fait effectuer quelques tours, la boucle 7 sera aspirée sur une certaine distance par l'embout. Ensuite, des dispositifs 11 et 12, constitués par exemple de crochets, pourront retirer de l'embout le début 4 et la fin 5 du fil qui sera ensuite sectionné, les deux extrémités étant alors amenées aux points requis par le fonctionnement de la machine à tisser.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. When a coil 1 is presented under the vacuum cleaner nozzle 10 and it is made to perform a few turns, the loop 7 will be sucked over a certain distance by the nozzle . Then, 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.

Il est clair que le début et la fin de fil obtenus par le sectionnement de la boucle ne correspondent pas nécessairement au début 4 et à la fin 5 du fil lors de l'envidage de la bobine. Effectivement, la fin 5 du fil d'une bobine classique est généralement trop courte pour être amenée au point requis par le fonctionnement de la machine à tisser. Faisant usage d'une bobine conforme à l'invention, il suffira de choisir convenablement le point de sectionnement sur la boucle 7 -- la seule contrainte étant que ce point de sectionnement ne doit pas correspondre au point de nouage -- pour obtenir toujours une fin de fil ou un début de fil de la longueur appropriée.It is clear that 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. Indeed, 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. Making use of a coil according to the invention, 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.

La figure 4 représente un porte-bobine permettant une mise en place automatique des bobines 1 évoquées ci-dessus afin d'assurer, par exemple, une alimentation automatique en fil 13 destiné aux insertions de trame sur une machine à tisser. Les bobines 1 sont amenées sur un convoyeur 14 et placées sur la courroie 15 du porte-bobine. La boucle 7 précitée pourra être recherchée par exemple à l'aide d'un dispositif de recherche de fil semblable à celui décrit plus haut, puis sectionnée, suite à quoi le début 4 et la fin 5 du fil sont amenés dans les dispositifs de pinçage 16 et 17. L'une de ces extrémités sera alors nouée à la fin du fil de la bobine précédente à l'aide du noueur 18 et l'autre, présentée de telle manière que la bobine suivante pourra y être nouée après un certain temps. Il est clair que cette installation possédera autant de dispositifs de pinçage 16, 17, 19 et 20 qu'il y a d'emplacement prévus pour les bobines.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.

Les dispositifs de pinçage 16 et 17 comprendront chacun par exemple deux pince-fils 21 et 22, montés comme illustré aux figures 5 et 6. Le pinçage des fils s'effectuera de telle manière que le début 4 du fil d'une nouvelle bobine sera présenté en chevauchement par rapport à la fin 5 du fil de la bobine précédente, suite à quoi les deux fils seront noués automatiquement comme l'illustre schématiquement le cerclage 23. Après le nouage, les bouts de fil 24 et 25 seront sectionnés comme illustré à la figure 7, de manière à obtenir une liaison aussi lisse que possible.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.

Il convient de noter que la liaison des extrémités évoquées ci-dessus peut également être réalisée par une épissure et non par nouage.It should be noted that the connection of the ends mentioned above can also be carried out by a splice and not by knotting.

Le champ de l'invention présentée ne se limite aucunement aux formes d'exécution décrites plus haut en guise d'exemples et représentées aux dessins en annexe; au contraire, les bobines et le dispositif de recherche de fil applicables conformément à l'invention, sont susceptibles de multiples variantes de réalisation sans sortir du cadre de l'invention.The scope of the invention presented is in no way limited to the embodiments described above by way of examples and shown in the accompanying drawings; on the contrary, the coils and the wire search device applicable in accordance with the invention are capable of multiple variants without departing from the scope of the invention.
