Description

MACHINE DE RETORDAGE D'UNE MATIERE TEXTILE MACHINE FOR CUTTING A TEXTILE MATERIAL
FILIFORMEFILAMENTARY
L'invention concerne le domaine technique des machines de transformation des matières textiles filiformes, notamment des fils textiles.The invention relates to the technical field of textile processing machines filiform textile materials, including.
Plus particulièrement, l'invention concerne les machines constituées d'une pluralité de positions de travail, chaque position comprenant, en alignement et en correspondance, en partie supérieure, un ensemble d'alimentation en fil et, en partie inférieure, un ensemble de transformation et de renvidage. Une application avantageuse concerne le domaine des machines de retordage, notamment des fils de verre, comportant avantageusement un organe dérouleur motorisé et un banc à anneau comme moyen de retordage et de renvidage.More particularly, the invention relates to machines consisting of a plurality of working positions, each position comprising, in alignment and in correspondence, in the upper part, a wire feeding assembly and, in the lower part, a transformation assembly. and winding. An advantageous application relates to the field of twisting machines, especially glass son, advantageously comprising a motorized unwinder and a ring bench as a means of twisting and winding.
On rappelle, pour une meilleure compréhension de la suite de la description et d'une manière parfaitement connue pour un homme du métier que, dans le cas d'un retordage sur banc à anneau, une bobine réceptrice est rendue solidaire d'une broche sur laquelle elle est mise en rotation élevée. Le fil, délivré à partir d'une bobine alimentaire disposée sur un organe support rotatif tel qu'une tavelle par exemple, selon une certaine vitesse d'avancement, passe par un guide-fil, généralement connu sous le nom de fixe-ballon disposé sensiblement dans le prolongement de l'axe de la broche, puis dans un deuxième guide-fil, généralement appelé curseur, libre de circuler sur un anneau coaxial à la broche entourant la bobine réceptrice. En tournant sur elle-même, la bobine réceptrice tracte le fil et l'entraîne en rotation, tandis que le fil entraîne le curseur en rotation et forme un ballon entre ledit curseur et le fixe-ballon. Cette rotation confère la torsion du fil sur lui-même. Le rapport entre la vitesse de rotation de la broche et la vitesse linéaire d'avancement du fil, détermine un taux de torsion.It will be recalled, for a better understanding of the rest of the description and in a manner perfectly known to a person skilled in the art, that, in the case of a twisting on a ring bench, a receiving reel is made integral with a spindle on which is rotated high. The yarn, delivered from a feed spool disposed on a rotary support member such as a tavel for example, according to a certain forward speed, passes through a guide wire, generally known as a fixed-balloon arranged substantially in the extension of the axis of the spindle, then in a second wire guide, generally called slider, free to circulate on a ring coaxial with the pin surrounding the receiver coil. By turning on itself, the receiver coil draws the wire and rotates it, while the wire drives the cursor in rotation and forms a balloon between said cursor and the fixed-balloon. This rotation gives the twisting of the thread on himself. The ratio between the rotational speed of the spindle and the linear speed of advance of the wire, determines a torsion rate.
Selon ce procédé, le fil s'enroule sur la bobine au droit du curseur, et donc au droit de l'anneau qui le guide en rotation. L'anneau est donc animé d'un mouvement de va-et-vient pour répartir le fil le long de la bobine. Le plus souvent, le fixe-ballon est lui-même animé d'un mouvement de déplacement vertical synchronisé avec celui de l'anneau, pour réguler la distance entre eux et donc la longueur du ballon et, par suite, la tension du fil résultant des forces centrifuges et aérodynamiques dans ce ballon.According to this method, the wire is wound on the spool at the right of the cursor, and therefore at the right of the ring which guides it in rotation. The ring is then moved back and forth to distribute the wire along the coil. Most often, the fixed-balloon is itself animated by a movement of vertical movement synchronized with that of the ring, to regulate the distance between them and therefore the length of the balloon and, consequently, the tension of the resulting yarn centrifugal and aerodynamic forces in this balloon.
Ce procédé de retordage et les machines mettant en œuvre un tel procédé sont parfaitement connus pour un homme du métier. Par exemple, l'architecture générale de ce type de machine et son mode de fonctionnement ressort de l'enseignement du brevet FR 2.789.409. Selon l'enseignement de ce brevet, l'anneau et le fixe-ballon sont montés sur un bâti central qui présente deux supports indépendants aptes, d'une part, à recevoir simultanément un mouvement de monte et baisse, au cours de la formation de l'enroulement de fil tordu et, d'autre part, être écartés l'un de l'autre en fin d'opération de câblage pour effectuer le cavage et/ou intervenir sur la machine.This twisting process and the machines implementing such a method are well known to those skilled in the art. For example, the general architecture of this type of machine and its mode of operation is apparent from the teaching of patent FR 2 789 409. According to the teaching of this patent, the ring and the fixed-balloon are mounted on a central frame which has two independent supports able, on the one hand, to simultaneously receive a movement up and down, during the formation of winding twisted wire and, secondly, be spaced from each other at the end of the wiring operation to perform the digging and / or intervene on the machine.
L'homme du métier sait par ailleurs que la qualité textile obtenue par ce type de procédé de retordage, repose sur la maîtrise du comportement dynamique du fil et des tensions qui en résultent, d'une part, entre la bobine alimentaire et le fixe-ballon et, d'autre part, entre le fixe-ballon et l'anneau. Entre la bobine alimentaire et le fixe-ballon, la trajectoire du fil est animée d'un mouvement alternatif consécutif du va-et-vient du point de défilement de la bobine. Ce mouvement de balayage forme un triangle qui se traduit par une variation de la longueur libre du fil et des angles d'embarrage du fil sur le fixe-ballon. La hauteur du triangle et son angle au sommet, dépendent de la distance entre un organe dérouleur et le fixe- ballon, et évoluent selon les mouvements de va-et-vient du fixe-ballon.Those skilled in the art also know that the textile quality obtained by this type of twisting process is based on the control of the dynamic behavior of the yarn and the resulting tensions, on the one hand, between the feed roll and the fastener. balloon and, on the other hand, between the balloon and the ring. Between the food reel and the fixed-balloon, the trajectory of the wire is animated by a reciprocating consecutive movement of the comings and goings of the point of travel of the reel. This scanning movement forms a triangle which results in a variation of the free length of the wire and the anchoring angles of the wire on the fixed-balloon. The height of the triangle and its angle at the top, depend on the distance between an unwinding unit and the fixed-balloon, and evolve according to the movements of back and forth of the fixed-balloon.
Entre le fixe-ballon et l'anneau, le fil est animé d'un mouvement de rotation conféré par la broche. La forme et le diamètre de ce ballon résultent de l'équilibre entre, d'une part, la force centrifuge et la résistance aérodynamique et, d'autre part, la tension du fil. La tension résulte de la différence entre la traction exercée par la broche via le curseur, et la force de retenue conférée sur le fil en amont du fixe-ballon. La qualité textile du procédé de retordage dépend des différentes distances et des angles de défilement.Between the fixed-balloon and the ring, the wire is animated by a rotational movement imparted by the spindle. The shape and the diameter of this balloon result from the balance between, on the one hand, the centrifugal force and the aerodynamic resistance and, on the other hand, the tension of the wire. The tension results from the difference between the traction exerted by the spindle via the slider, and the retaining force imparted on the yarn upstream of the fixed-balloon. The textile quality of the twisting process depends on the different distances and the scrolling angles.
Par exemple, il est connu que la distance élevée entre le fixe-ballon et l'organe de dévidage de bobine alimentaire, permet de réduire les irrégularités de vitesse et de tension du mouvement de va et vient du point de dévidage. Toutefois, la capacité d'augmenter certaines distances est limitée étant donné que l'opérateur doit pouvoir accéder aux bobines alimentaires ou autres ensembles d'alimentation pour le chargement et le lancement du fil.For example, it is known that the high distance between the fixed-balloon and the reel feed member, reduces the irregularities of speed and tension of the movement back and forth from the unwinding point. However, the ability to increase certain distances is limited because the operator must be able to access food reels or other feed assemblies for loading and throwing the yarn.
Par ailleurs, il est apparu important d'optimiser le rendement de production en augmentant les intervalles d'intervention pour le chargement et le déchargement des bobines alimentaires et des bobines de réception. Il en résulte que ces bobines sont d'un poids élevé, pouvant dépasser les 25 Kg, de sorte que le chargement et déchargement des bobines alimentaires dans la partie supérieure de la machine, est particulièrement pénible.Furthermore, it appeared important to optimize the production yield by increasing the intervention intervals for the loading and unloading of food rolls and receiving rolls. As a result, these coils are of a high weight, which may exceed 25 Kg, so that the loading and unloading of the food rolls in the upper part of the machine, is particularly painful.
Pour tenter de remédier à ces inconvénients, une solution ressort par exemple de l'enseignement du brevet FR 2.742.167. Selon l'enseignement de ce brevet, l'ensemble d'alimentation en fils à traiter est constitué par un module amovible apte à être adapté sur le bâti de la machine supportant les l'ensemble de retordage, notamment les broches. Ce module, qui constitue un organe indépendant, doit être désolidarisé de la machine pour être déplacé vers une zone de chargement et déchargement. Cette solution ne donne pas totalement satisfaction étant donné qu'elle nécessite l'utilisation d'un organe indépendant pour le transfert des bobines, lequel organe n'est pas intégré à la machine. Cet organe de manutention est complexe et nécessite une infrastructure importante.In an attempt to remedy these drawbacks, a solution emerges for example from the teaching of FR 2,742,167. According to the teachings of this patent, the son feed assembly to be treated is constituted by a removable module adapted to be fitted on the frame of the machine supporting the twisting assembly, including the pins. This module, which is an independent body, must be separated from the machine to be moved to a loading and unloading area. This solution does not give complete satisfaction since it requires the use of an independent body for the transfer of the coils, which member is not integrated into the machine. This handling device is complex and requires a large infrastructure.
Une autre solution a été proposée pour d'autres types de machines, comme il ressort du brevet FR 2.794.136. Selon l'enseignement de ce brevet, les bobines alimentaires, qui sont fixes pendant la production, sont disposées sur des supports que l'on peut abaisser par un système de parallélogramme associé à un mouvement de rotation.Another solution has been proposed for other types of machines, as is apparent from patent FR 2,794,136. According to the teaching of this patent, the food coils, which are fixed during production, are arranged on supports that can be lowered by a parallelogram system associated with a rotational movement.
Une telle solution n'est pas applicable au type de machines concernées par la présente invention. En effet :Such a solution is not applicable to the type of machines concerned by the present invention. Indeed :
- Cette solution ne peut pas s'appliquer aux machines dans lesquelles les bobines alimentaires sont disposées sur des dérouleurs rotatifs motorisés, car il faut aussi déplacer les moteurs et leur alimentation électrique. - Cette solution ne peut pas s'appliquer lorsque la position relative des dérouleurs par rapport à la broche, influe le procédé, ce qui exige un positionnement précis.- This solution can not be applied to machines in which the food coils are placed on motorized rotary openers, because it is also necessary to move the motors and their power supply. - This solution can not be applied when the relative position of the unwinders with respect to the spindle, influences the process, which requires precise positioning.
- Cette solution bloque l'accès frontal à la machine lorsque le système est abaissé, ce qui impose qu'il soit individuel.- This solution blocks front access to the machine when the system is lowered, which requires that it be individual.
- Cette solution nécessite des moyens d'assistance pneumatique individuels et indépendants pour chaque position de travail.This solution requires individual and independent pneumatic assistance means for each working position.
On observe par ailleurs qu'il n'est pas possible de diminuer, d'une manière significative, la hauteur de la machine étant donné que cette hauteur est limitée par le procédé textile et la qualité souhaitée comme indiqué précédemment.It is also observed that it is not possible to significantly reduce the height of the machine since this height is limited by the textile process and the desired quality as indicated above.
Compte tenu de ce qui précède, il résulte que les machines de retordage ont fréquemment une hauteur du banc de broches de retordage à environ 250 et 300 mm du sol, obligeant l'opérateur à se baisser, tandis que la hauteur de l'ensemble d'alimentation, par exemple les broches d'alimentation, est sensiblement à 2 mètres du sol, nécessitant, de la part de l'opérateur, un effort important pour soulever les bobines en vue du chargement et déchargement.In view of the foregoing, it follows that the twisting machines frequently have a height of twisting spindle bench at about 250 and 300 mm from the ground, forcing the operator to bend, while the height of the set of feeding, for example the feed pins, is substantially 2 meters above the ground, requiring, on the part of the operator, a significant effort to lift the reels for the purpose of loading and unloading.
A partir de cet état de la technique, le problème que se propose de résoudre l'invention est de pouvoir améliorer les conditions de travail de l'opérateur, notamment au niveau du chargement et déchargement des différentes bobines alimentaires notamment, et d'améliorer la qualité du travail textile, tout en donnant les possibilités de réglage supplémentaires. Pour résoudre un tel problème, il a été conçu et mis au point une machine de retordage d'une matière textile filiforme comprenant un bâti principal fixe recevant une pluralité de positions de travail, chaque position comprenant en alignement et en correspondance : - en partie haute, un ensemble d'alimentation en matière textile ;From this state of the art, the problem to be solved by the invention is to be able to improve the working conditions of the operator, particularly with regard to the loading and unloading of the various food reels in particular, and to improve the quality of textile work, while giving additional adjustment possibilities. To solve such a problem, it has been designed and developed a twisting machine of a threadlike textile material comprising a fixed main frame receiving a plurality of working positions, each position comprising in alignment and in correspondence: - in the upper part a textile feed assembly;
- en partie basse, un ensemble de renvidage et de retordage.- In the lower part, a set of winding and twisting.
Selon l'invention, l'ensemble d'alimentation est assujetti à des moyens aptes à le soumettre à un mouvement de déplacement vertical correspondant à un réglage en hauteur avec éventuellement capacité de blocage en position, par rapport à l'ensemble de renvidage pour permettre, d'une manière concomitante, de faciliter le chargement et le déchargement des organes constituant ledit ensemble d'alimentation sous un effet de rabaissement et/ou d'assurer un réglage textile, le niveau haut correspondant à une position de travail, tandis que le niveau bas correspond à une position de chargement- déchargement.According to the invention, the supply assembly is subject to means capable of subjecting it to a vertical displacement movement corresponding to an adjustment in height with possible locking capacity in position, with respect to the assembly of winding to allow in a concomitant manner, to facilitate the loading and unloading of the members constituting said feed assembly under a lowering effect and / or to provide a textile adjustment, the high level corresponding to a working position, while the low level corresponds to a loading-unloading position.
A titre d'exemple indicatif, et d'une manière parfaitement connue pour un homme du métier, l'ensemble de renvidage comprend : - une broche verticale entraînée en rotation et sur laquelle est montée une bobine de réception ;As an indicative example, and in a manner perfectly known to those skilled in the art, the winding assembly comprises: a vertical spindle rotated and on which is mounted a receiving coil;
- un système anneau-curseur entourant ladite broche, la matière textile formant un ballon entre le curseur qu'elle entraîne en rotation et un élément de guidage dit fixe-ballon disposé dans l'axe géométrique de la broche et au-dessus de cette dernière ;a ring-slider system surrounding said spindle, the textile material forming a balloon between the slider which it rotates and a so-called fixed-balloon guide element disposed in the geometric axis of the spindle and above it ;
- le système anneau-curseur et fixe-ballon est animé d'un mouvement de monte et baisse ; L'ensemble d'alimentation est constitué par des broches alimentaires telles que des tavelles par exemple, lesquelles sont avantageusement motorisées.- The ring-slider and fixed-balloon system is driven by a rising and falling movement; The supply assembly is constituted by food pins such as tavelles for example, which are advantageously motorized.
Pour résoudre le problème posé de rapprocher l'ensemble d'alimentation par rapport à l'ensemble de renvidage et de retordage, les moyens de dévidage et organes associés sont regroupés sur une platine ou châssis monté avec capacité de réglage et de guidage en hauteur sur une partie du bâti en étant asservi à un dispositif de monte et baisse.To solve the problem of bringing the supply assembly relative to the winding and twisting assembly, the unwinding means and associated members are grouped on a plate or chassis mounted with adjustment capacity and height guidance on a part of the frame being enslaved to a device for going up and down.
La platine ou châssis du ou des ensembles d'alimentation évolue entre une position supérieure dite de travail et une position inférieure dite de chargement-déchargement, la position supérieure est utilisée lorsque les broches correspondantes aux ensembles d'alimentation associés sont en production, tandis que la position inférieure est sélectionnée lorsque les broches sont arrêtées pour l'évacuation d'un support vide et l'installation d'une nouvelle bobine de l'ensemble d'alimentation avant de relancer la production.The platen or frame of the supply unit or assemblies evolves between a so-called upper working position and a lower so-called loading-unloading position, the upper position is used when the pins corresponding to the associated feed assemblies are in production, while the lower position is selected when the spindles are stopped for evacuation of an empty support and the installation of a new spool of the feed assembly before restarting production.
Selon une autre caractéristique, la platine ou châssis coopère avec des organes d'entraînement du type mécanique et/ou électrique et/ou pneumatique et/ou hydraulique. Les organes d'entraînement sont actionnés manuellement ou commandés.According to another characteristic, the plate or frame cooperates with drive members of the mechanical and / or electrical and / or pneumatic and / or hydraulic type. The drive members are operated manually or controlled.
A partir de cette conception de base : soit chaque position de travail présente une platine ou châssis ; soit la platine ou châssis est commun à l'ensemble des positions de travail ; soit la platine regroupe les organes de dévidage d'un groupe de position de travail qui correspond à un découpage sectionnel.From this basic design: either each working position has a plate or frame; either the plate or frame is common to all work positions; either the platen groups the unwinding members of a working position group which corresponds to a sectional cutting.
Selon une autre caractéristique, dans le cas où le bâti de machine présente une structure verticale dont chacune des faces comprend, pour chaque position de travail, un ensemble d'alimentation et un ensemble de renvidage :According to another feature, in the case where the machine frame has a vertical structure, each of the faces comprises, for each working position, a feed assembly and a winding assembly:
- les ensembles d'alimentation de toutes les positions de travail d'une même face sont associés à une platine de déplacement vertical indépendante de celle où sont associés les ensembles d'alimentation de l'autre face ;the supply assemblies of all the working positions of one and the same face are associated with a vertical displacement plate independent of that which are associated with the supply assemblies of the other face;
- ou bien, chaque face est subdivisée en sections d'un nombre déterminé de positions de travail, les ensembles d'alimentation de chaque section sont regroupés sur une platine de déplacement vertical indépendante de celle des sections adjacentes.- Or, each face is subdivided into sections of a determined number of working positions, the feed assemblies of each section are grouped on a vertical displacement plate independent of that of the adjacent sections.
Par ailleurs, le système anneau-curseur et le fixe-ballon relatifs à une position de travail, sont commandés par des dispositifs de monte et baisse qui leurs sont propres et indépendants du système monte et baisse de l'ensemble d'alimentation.Furthermore, the ring-slider system and the fixed-balloon relative to a working position, are controlled by raising and lowering devices which are their own and independent of the system up and down the supply assembly.
Selon l'invention :According to the invention:
- la commande du dispositif animant le mouvement de monte et baisse des ensembles d'alimentation, est inter-verrouillée avec la commande des autres organes de la machine pour que la production ne puisse pas être démarrée lorsque lesdits ensembles sont en position basse ;- The control of the device animating the movement up and down of the feed assemblies, is interlocked with the control of the other parts of the machine so that the production can not be started when said sets are in the low position;
- la commande du dispositif assurant le mouvement de monte et baisse des fixe-ballons et capteurs associés, est interconnectée avec la commande des dispositifs de monte et baisse des ensembles d'alimentation, de sorte que les fixe-ballons sont abaissés lorsque l'ensemble d'alimentation correspondant est en position basse ;the control of the device ensuring the up and down movement of the fixed balloons and associated sensors is interconnected with the control devices for raising and lowering the power supply units, so that the fixed balloons are lowered when the corresponding power supply unit is in the low position;
L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels :The invention is described below in more detail with reference to the figures of the accompanying drawings, in which:

La machine de retordage est du type de celle comprenant un bâti principal (1) fixe recevant une pluralité de positions de travail. Chaque position comprend, en alignement et en correspondance, en partie haute, un ensemble d'alimentation (A) et, en partie basse, un ensemble de renvidage et de retordage (R). On désigne par (4) la matière filiforme à traiter sous forme notamment d'un fil. D'une manière connue, le bâti principal (1) présente une embase (la) reposant au sol par l'intermédiaire de pieds, par exemple, et présentant sensiblement, dans sa partie médiane, une structure porteuse verticale (Ib). En partie basse, l'ensemble de renvidage et de retordage (R) comprend, par exemple, des broches de retordage (5) disposées côte à côte, fixées au niveau inférieur du bâti, par exemple sur l'embase (la) constituant une poutre. Les différentes broches de retordage (5) reçoivent des bobines de réception (7).The twisting machine is of the type of that comprising a fixed main frame (1) receiving a plurality of working positions. Each position comprises, in alignment and in correspondence, in the upper part, a feeding assembly (A) and, in the lower part, a set of winding and twisting (R). The term "(4) filiform material to be treated in particular form of a wire. In known manner, the main frame (1) has a base (la) resting on the ground via feet, for example, and having substantially, in its middle part, a vertical bearing structure (Ib). In the lower part, the winding and twisting assembly (R) comprises, for example, twisting spindles (5) arranged side by side, fixed at the lower level of the frame, for example on the base (la) constituting a beam. The different twisting pins (5) receive receiving coils (7).
D'une manière coaxiale aux broches de retordage (5), sont disposés des anneaux (10) de guidage d'un curseur (9) disposés côte à côte par l'intermédiaire d'un système (11) apte à conférer un mouvement de va et vient sensiblement vertical, généralement connu sous le nom de mouvement monte et baisse. Le système (11) est disposé par exemple au niveau de la structure verticale (Ib) du bâti. Des fixe-ballons (8) et des éventuels capteurs ou guide-fils, sont disposés côte à côte et assujettis à un système (6) apte à leur conférer, comme précédemment, un mouvement de va-et- vient sensiblement vertical. Le système (6) peut également être positionné au niveau de la structure vertical (Ib) du bâti. On rappelle que ces dispositions sont parfaitement connues par l'homme du métier et ressortent par exemple de l'enseignement des brevets précités FR 2.789.409 et FR 2.742.167.In coaxial manner with the twisting spindles (5) are arranged rings (10) for guiding a slider (9) arranged side by side via a system (11) adapted to impart a movement of back and forth substantially vertical, usually known as movement up and down. The system (11) is arranged for example at the vertical structure (Ib) of the frame. Fixed balloons (8) and any sensors or wire guide, are arranged side by side and subject to a system (6) capable of conferring, as before, a movement of back and forth substantially vertical. The system (6) can also be positioned at the vertical structure (Ib) of the frame. It is recalled that these provisions are well known to those skilled in the art and emerge for example from the teaching of the above-mentioned patents FR 2 789 409 and FR 2 7 42 677.
Selon l'invention, l'ensemble d'alimentation (A) peut être constitué par des bobines alimentaires (2) montées sur des organes de déroulage (3), en étant assujetti à des moyens aptes à le soumettre à un mouvement de déplacement vertical correspondant à un réglage en hauteur par rapport à l'ensemble de renvidage et de retordage précité, pour permettre, d'une manière concomitante, de faciliter le chargement et le déchargement des bobines alimentaires (2) sous un effet de rabaissement et/ou d'assurer un réglage textile. Comme il sera indiqué dans la suite de la description, le niveau haut (14) de l'ensemble d'alimentation (2, 3) correspond à une position de travail, tandis que le niveau bas (15) correspond à une position de chargement/déchargement.According to the invention, the feed assembly (A) can be constituted by food coils (2) mounted on unwinding members (3), being subjected to means able to subject it to a vertical movement movement corresponding to a height adjustment with respect to the assembly of said winding and twisting, to allow, of a concomitantly, facilitate the loading and unloading of food reels (2) under a lowering effect and / or provide a textile adjustment. As will be indicated in the following description, the high level (14) of the supply assembly (2, 3) corresponds to a working position, while the low level (15) corresponds to a loading position. /unloading.
Par exemple, comme le montrent les figures des dessins, les organes de déroulage (3) sont montés sur des platines intermédiaires (12) accouplées au bâti (1), par un dispositif de monte et baisse (13) apte à assurer un déplacement substantiellement vertical. Ce dispositif de monte et baisse (13) peut être constitué de moyens mécaniques tels que, par exemple, des vérins, des leviers, des systèmes à vis, des systèmes de treuil, ou tout autre moyen éventuellement associé à des organes de blocage en position. L'ensemble du dispositif (13) peut être déplacé manuellement ou asservi à des moyens de commande, tels que des organes électriques, hydrauliques, pneumatiques, ...For example, as shown in the figures of the drawings, the unwinding members (3) are mounted on intermediate plates (12) coupled to the frame (1), by a raising and lowering device (13) capable of ensuring a substantial displacement. vertical. This raising and lowering device (13) can consist of mechanical means such as, for example, cylinders, levers, screw systems, winch systems, or any other means possibly associated with locking members in position. . The entire device (13) can be moved manually or slaved to control means, such as electrical, hydraulic, pneumatic, etc.
Compte tenu des caractéristiques à la base de l'invention, le dispositif (13) de déplacement en hauteur de la platine (12) recevant les organes dérouleurs, peut être utilisé pour ajuster la position desdits dérouleurs en fonction des réglages textiles de la machine. Le dispositif est actionné lors du réglage de la machine en vue du lancement d'une nouvelle production.Given the characteristics underlying the invention, the device (13) for moving the height of the plate (12) receiving the unwinding members, can be used to adjust the position of said unwinders depending on the textile settings of the machine. The device is actuated during the setting of the machine for the launch of a new production.
Dans une forme de réalisation, les organes dérouleurs (3), dans toutes les positions de travail, sont associés au même dispositif de monte et baisse (13) par l'intermédiaire de la platine (12). Dans le cas où la machine est subdivisée en faces indépendantes (figure 4) et délimitée en deux sections, une broche (5) de chaque section peut être arrêtée et démarrée indépendamment de l'autre, à des fins de déchargement et de rechargement. Dans ce cas, les dérouleurs (3), de toutes les positions de travail d'une même face de machine, sont associés à un dispositif de monte et baisse (13) par l'intermédiaire d'une platine (12), indépendant de celui auquel sont associés les organes enrouleurs de l'autre face.In one embodiment, the unwinding members (3), in all working positions, are associated with the same up and down device (13) via the plate (12). In the case where the machine is subdivided into independent faces (Figure 4) and delimited in two sections, a pin (5) of each section can be stopped and started independently of the other, for unloading and reloading purposes. In this case, the unwinders (3), of all the working positions of the same machine face, are associated with a raising and lowering device (13) via a plate (12), independent of the one with which the winding organs on the other side are associated.
Dans une forme de réalisation, la machine, ou chaque face de machine, peut être subdivisée en section, par exemple de 4, 6 ou 8 positions d'une même face contiguë. Les broches (5) de chaque section peuvent être arrêtées et démarrées indépendamment des modules adjacents à des fins de chargement et de déchargement. Les organes enrouleurs (3) correspondant aux broches (5) de chaque module, seront regroupés sur une platine (12) indépendante, et équipée des moyens de monte et baisse (13) indépendants de ceux des organes dérouleurs adjacents.In one embodiment, the machine, or each machine face, can be subdivided into sections, for example 4, 6 or 8 positions of the same contiguous face. The pins (5) of each section can be stopped and started independently of the adjacent modules for loading and unloading purposes. The reels (3) corresponding to the pins (5) of each module, will be grouped on a plate (12) independent, and equipped with means of up and down (13) independent of those adjacent unwinding organs.
Quelle que soit la forme de réalisation de la machine de retordage, les bancs d'anneaux (10) et les fixe-ballons (8) peuvent être commandés par des dispositifs monte et baisse (11) et (6), indépendants des sections adjacentes. A noter que la commande du dispositif monte et baisse (13) des organes dérouleurs (3), peut être interconnectée par la commande des autres organes de la machine par des moyens mécaniques, électriques ou informatiques, pour que la production textile ne puisse pas être démarrée lorsque les modules dérouleurs sont en position basse. De même, la commande du dispositif (6) assurant le mouvement de monte et baisse des fixe-ballons (8) et des éventuels capteurs associés, peut être interconnectée par des moyens mécaniques, électriques ou informatiques, avec la commande du dispositif de monte et baisse (13) de sorte que les fixe-ballons (8) sont abaissés lorsque les organes dérouleurs (3) sont en position basse.Whatever the embodiment of the twisting machine, the ring benches (10) and the fixed-balloons (8) can be controlled by up and down devices (11) and (6), independent of the adjacent sections . Note that the control of the device up and down (13) of the unwinding units (3), can be interconnected by the control of the other organs of the machine by mechanical, electrical or computer, so that the textile production can not be started when the unwind modules are in the down position. Similarly, the control of the device (6) ensuring the upward and downward movement of the fixed-balloons (8) and any associated sensors, can be interconnected by mechanical, electrical or computer means, with the control of the mounting device and drop (13) so that the fixed-balloons (8) are lowered when the unwinding members (3) are in the low position.
Le dispositif (13) est déterminé pour évoluer entre deux positions, à savoir la position haute dite de travail (14) et la position basse dite de chargement et déchargement (15). Le dispositif est actionné lorsque la production est interrompue pour effectuer les opérations de déchargement et rechargement de la machine. Il en résulte que la position haute (14) est utilisée lorsque les broches correspondantes aux organes de déroulage (2, 3) associés sont en production, la position basse (15) étant sélectionnée lorsque lesdites broches sont arrêtées afin de permettre à l'opérateur d'évacuer le support vide d'installer une nouvelle bobine alimentaire avant de relancer la production.The device (13) is determined to move between two positions, namely the so-called high working position (14) and the so-called low loading and unloading position (15). The device is operated when production is interrupted to perform the unloading and reloading operations of the machine. As a result, the up position (14) is used when the pins corresponding to the unwinding members (2, 3) associated are in production, the low position (15) being selected when said pins are stopped to allow the operator to evacuate the empty rack to install a new food coil before restarting production.
A noter que la position haute (14) de travail peut être fixe ou prédéterminée en fonction d'un réglage textile de la machine. Par exemple, cette position haute est évolutive en cours de formation de bobine selon une loi d'évolution préprogrammée en fonction du réglage textile. A partir de ce résultat, le dispositif (13) est assujetti à des moyens de pilotage du type mécanique, électrique ou électronique, aptes à assurer la remontée à la hauteur de départ programmé, puis à piloter les platines supportant les dérouleurs à la position haute de travail prédéterminée, afin d'effectuer le mouvement selon la loi d'évolution préprogrammée. Les avantages ressortent bien de la description, en particulier on souligne et on rappelle : la possibilité de déplacer verticalement l'ensemble d'alimentation afin de le rabaisser pour faciliter le travail de l'opérateur notamment pour le chargement et le déchargement des bobines que présente ledit ensemble ; la possibilité de régler en hauteur l'ensemble d'alimentation pour permettre, d'une manière concomitante, un réglage textile. Note that the upper position (14) of work can be fixed or predetermined depending on a textile setting of the machine. For example, this high position is scalable during coil formation according to a law of evolution preprogrammed according to the textile setting. From this result, the device (13) is subject to control means of the mechanical type, electrical or electronic, able to ensure the recovery to the programmed starting height, then to drive the plates supporting the unwinders to the high position predetermined work, in order to perform the movement according to the law of preprogrammed evolution. The advantages are apparent from the description, in particular it emphasizes and recalls: the possibility of moving vertically the supply assembly to lower it to facilitate the work of the operator including the loading and unloading of the reels that presents said set; the possibility of adjusting the height of the feed assembly to allow, concomitantly, a textile adjustment.
