Description
La presente invention concerne une machine pour la fabrication de chenille selon le préambule de la revendication 1.The present invention relates to a machine for manufacturing a track according to the preamble of
Une telle machine est connue du document EP-A-260206.Such a machine is known from document EP-A-260206.
On connaît des machines pour la fabrication de chenille qui sont équipées d'une motorisation centralisée dont dérive le mouvement de tous les groupes tournants qui concourent à la formation du produit. Plus en particulier, dans ces machines, la transmission est effectuée au moyen de cones à poulies et de courroies élastiques qui relient un arbre moteur avec les différents groupes opérationnels. Pour régler les paramètres qui déterminent la formation de la chenille, comme par exemple la torsion, la vitesse de diminution, la vitesse de coupe, etc., il est donc nécessaire d'intervenir manuellement pour déplacer les courroies sur les poulies appropriées des différents cones ou bien de remplacer lesdites courroies, mais toujours avec la machine à l'arrêt et en travaillant sur l'arrière de la machine. Par ailleurs, les fils qui alimentent les têtes à filer et les autres groupes proviennent d'un cantre de support des bobines qui est placé, pour des raisons d'encombrement, sur le côté de la machine.There are known machines for the manufacture of tracks which are equipped with a centralized motorization from which the movement of all the rotating groups which contribute to the formation of the product is derived. More particularly, in these machines, the transmission is carried out by means of pulley cones and elastic belts which connect a motor shaft with the various operational groups. To adjust the parameters that determine the formation of the track, such as twist, decrease speed, cutting speed, etc., it is therefore necessary to manually intervene to move the belts on the appropriate pulleys of the different cones or else to replace said belts, but always with the machine stopped and working on the rear of the machine. Furthermore, the threads which feed the spinning heads and the other groups come from a reel support strip which is placed, for reasons of space, on the side of the machine.
Ces machines connues présentent différents inconvénients parmi lesquels: un encombrement considérable dû auxdites courroies qui, à partir de l'arbre moteur, s'étendent dans toutes les directions en occupant par conséquent une place considérable aussi bien en profondeur qu'en hauteur; une vitesse de production limitée par les vibrations dues aux longues courroies de transmission et au poids élevé des poulies; une consommation d'énergie élevée due aux nombreuses masses, de courroies et de poulies, à mettre en mouvement; un réglage des paramètres de travail incommode et peu précis, du fait qu'il doit être effectué à la main et avec la machine arrêtée.These known machines have various drawbacks, among which: a considerable bulk due to said belts which, starting from the motor shaft, extend in all directions thus occupying a considerable place both in depth and in height; a production speed limited by the vibrations due to the long transmission belts and the heavy weight of the pulleys; high energy consumption due to the many masses, belts and pulleys to be set in motion; inconvenient and imprecise adjustment of the working parameters, since it must be carried out by hand and with the machine stopped.
Ceci entra ne également un manque d'uniformité dans le produit fini, principalement dû à un manque de synchronisme précis entre les groupes qui concourent à la formation du filé, ainsi qu'un coût plus élevé en raison des arrêts de travail. D'autres inconvénients sont provoqués par le long parcours que les fils doivent accomplir du cantre porte-bobines jusqu'aux groupes de travail.This also led to a lack of uniformity in the finished product, mainly due to a lack of precise synchronism between the groups which contribute to the formation of the yarn, as well as a higher cost due to work stoppages. Other drawbacks are caused by the long journey that the wires have to complete from the reel holder to the working groups.
On connaît en outre (EP-A-260206), une machine pour la réalisation de fils fantasie avec une pluralité de positions de travails montées côté a côté sur un bâti support, chaque position de travail comportant une source d'alimentation d'au moins deux fils dont l'un est destiné à former l'âme et l'autre l'effet; au moins une broche creuse à l'intérieur du fût de laquelle passent les fils précités, ladite broche supportant une bobine de fil de liage, et les fils d'âme et d'effet étant amenés à cette broche creuse par l'intermédiaire de délivreurs du type à entraînement positif, chaque délivreur étant monté sur une ligne d'arbre indépendante commandée; des moyens de renvidage du fil fantasie formé. Les arbres de commande des délivreurs de fil d'âme et d'effet et du système de renvidage sont entraînés individuellement par des moteurs synchronisés commandés par un ordinateur pilotant en commande numérique en ensemble diviseur+convertisseur de fréquence de telle sorte que lesdits fils puissent indifféremment devenir effet ou âme.
Mais cette machine n'est pas apte à la production de la chenille.We also know (EP-A-260206), a machine for making fantasy yarns with a plurality of work positions mounted side by side on a support frame, each working position comprising a power source of at least two wires, one of which is intended to form the soul and the other of which is the effect; at least one hollow spindle inside the barrel through which the aforementioned threads pass, said spindle supporting a coil of binding thread, and the core and effect threads being brought to this hollow spindle by means of deliverers of the positive drive type, each deliverer being mounted on a controlled independent shaft line; means for winding up the fantasy yarn formed. The control shafts of the core and effect wire deliverers and of the winding system are driven individually by synchronized motors controlled by a computer controlling digitally as a divider + frequency converter so that said wires can be interchanged become effect or soul.
But this machine is not suitable for the production of the track.
La présente invention a pour but d'éliminer ces inconvénients.The present invention aims to eliminate these drawbacks.
Ce résultat a été atteint conformément à l'invention selon la revendication 1 en adoptant l'idée d'utiliser une motorisation multiple des différents groupes de travail, c'est-à-dire, plus particulièrement, d'équiper la machine pour la fabrication de chenille de plusieurs moteurs disposés le long de la ligne de formation du filé et qui sont réglables séparément au moyen d'une seule unité de commande, laquelle effectue également le maintien des synchronismes entre les différents groupes.This result was achieved in accordance with the invention according to
Les avantages obtenus grâce à la présente innovation consistent essentiellement dans le fait qu'il est possible d'éliminer presque complètement la présence des courroies élastiques, en limitant de toute façon considérablement leur longueur et en économisant ainsi beaucoup de place aussi bien en profondeur qu'en hauteur; que le réglage des paramètres de travail est effectué facilement en agissant directement sur chaque groupe ou tête individuellement et conjointement au moyen d'une unité centrale de commande, de manière précise, continue et sans interrompre la production, ce qui permet de rendre le produit plus homogène et économique; que, grâce à la suppression des longues courroies de transmission et des lourds cônes à poulies, on obtient des vibrations sérieusement réduites et, par conséquent, il est possible de travailler à des vitesses plus élevées avec une sécurité même supérieure vis-à-vis d'éventuelles ruptures; que, étant donné l'encombrement plus faible, il est possible de placer le cantre porte-bobines directement à l'avant de la machine, en diminuant ainsi la longueur du parcours du fil retenu et, par conséquent, les possibilités de rupture; qu'il est possible de libérer l'arrière de la machine, et donc d'obtenir deux fronts de travail; que la diminution des masses à déplacer entra nent une économie de puissance absorbée.The advantages obtained thanks to the present innovation essentially consist in the fact that it is possible to almost completely eliminate the presence of elastic belts, in any case considerably limiting their length and thus saving a lot of space both in depth and in in height; that the adjustment of the working parameters is carried out easily by acting directly on each group or head individually and jointly by means of a central control unit, precisely, continuously and without interrupting production, which makes the product more homogeneous and economical; that thanks to the elimination of long transmission belts and heavy pulley cones, seriously reduced vibrations are obtained and, consequently, it is possible to work at higher speeds with even greater safety vis-à-vis '' possible ruptures; that, given the smaller footprint, it is possible to place the reel holder creel directly in front of the machine, thereby reducing the length of the path of the retained wire and, therefore, the possibility of breakage; that it is possible to free the rear of the machine, and therefore to obtain two working fronts; that the reduction in the masses to be moved leads to a saving in absorbed power.
