Abstract

A sliding base is guided for vertical movement on an upright of the traverse mechanism. It bears a camera having its lens directed along a horizontal axis toward a vertical bank of lights. A drum supported by uprights and driven rotatingly by a motor can move back and forth on rails, while the traversing carriage bearing vertical rolls guiding a cable can likewise move parallel to the axis of the drum in order to check and, if neccessary, modify the approach angle formed by the incoming cable about to be laid on the winding. The silhouette of the zone of the winding where the turns are laid down is formed on a receiving surface within the camera, this surface taking the form of a photodiode grid, the periodic scanning of which yields signals sensing the conditions under which the cable is being wound.

Description

La présente invention concerne l'enroulement de câbles de grand diamètre sur des bobines. Par câble de grand diamètre on entend des câbles électriques isolés dont le diamètre extérieur est supérieur à 10 mm. Cependant, en général, le diamètre des câbles ne dépasse pas 60 mm. Normalement, ces câbles sont produits en segments dont la longueur est aussi grande que possible et ils sont enroulés sur des bobines dont les dimensions atteignent souvent plusieurs mètres de diamètre. Les bobinoirs supportant ces bobines et les entraînant en rotation sont des appareils de grande masse nécessitant pour leur entraînement des moteurs puissants et volumineux . Le brevet CH 576 392 par exemple décrit un bobinoir de ce genre dans lequel le chariot de trancanage est supporté par un rail parallèle à l'axe du support de bobine et le support de bobine lui-même comporte deux montants indépendants l'un de l'autre et susceptibles de se déplacer sur des rails également parallèles au même axe. 0n peut ainsi réaliser soit des opérations de trancanage dans lesquelles le chariot de trancanage et par conséquent le guide-câble se déplacent parallèlement à l'axe de la bobine sur toute la longueur de cette dernière, soit des opérations dites d'auto -trancanage dans lesquelles le chariot de trancanage reste fixe et c'est l'ensemble du support de bobine qui se déplace en translation devant le chariot de trancanage.The present invention relates to the winding of large diameter cables on spools. By large diameter cable is meant insulated electrical cables with an outside diameter greater than 10 mm. However, in general, the diameter of the cables does not exceed 60 mm. Normally, these cables are produced in segments as long as possible and they are wound on spools whose dimensions often reach several meters in diameter. The winders supporting these coils and driving them in rotation are large mass devices requiring for their drive powerful and bulky motors. Patent CH 576,392, for example, describes a winder of this kind in which the cutting trolley is supported by a rail parallel to the axis of the spool holder and the spool holder itself has two independent uprights, one of the 'other and likely to move on rails also parallel to the same axis. 0n can thus carry out either cutting operations in which the cutting carriage and consequently the cable guide move parallel to the axis of the spool over the entire length of the latter, or so-called self-cutting operations in which the cutting trolley remains fixed and it is the whole of the reel support which moves in translation in front of the cutting trolley.

On sait depuis longtemps réaliser des opérations de trancanage automatiques sur des bobinoirs de petites dimensions prévus pour la formation de bobines de fils téléphoniques par exemple, ces bobines ayant des joues atteignant un diamètre de 40 cm. Dans ce cas, le chariot de trancanage est mobile devant le support de bobine et son entraînement est connecté à l'entraînement de la bobine de sorte que la vitesse du trancanage est proportionnelle à la vitesse de l'enroulement.It has long been known to carry out automatic cutting operations on winders of small dimensions intended for the formation of coils of telephone wires for example, these coils having cheeks reaching a diameter of 40 cm. In this case, the carriage of cutting is movable in front of the reel support and its drive is connected to the drive of the reel so that the speed of the cutting is proportional to the speed of the winding.

Toutefois, lorsqu'il s'agit d'enrouler des câbles de grandes dimensions il n'est pas possible de commander une opération de trancanage automatique en rendant simplement la vitesse du chariot de trancanage proportionnelle à la vitesse de rotation dé la bobine et jusqu'à maintenant il était nécessaire que l'opération de trancanage soit surveillée de façon constante par un opérateur. Pour illustrer les conditions mécaniques dans lesquelles les spires successives du câble se déposent sur le fût de la bobine on considérera tout d'abord la fig. 1 qui montre de façon schématique une bobine 1 sur laquelle un câble 2 est en train de se déposer spire par spire. La bobine 1 comporte un fût cylindrique 3 et deux flasques d'extrémité 4 et 5 aussi appelées joues ayant la forme de disques. Le câble 2 est accroché par son extrémité dans un trou 6 ménagé dans le fût 3 de la bobine 1. Celle-ci est entraînée en rotation dans le sens de la flèche A, de sorte qu'une première spire se dépose au contact du flasque 4. Toutefois, à la fin de la première spire, le câble 2 doit effectuer un mouvement de déviation sur la gauche afin que la seconde spire vienne se placer parallèlement et au contact de la première. Ainsi, l'enroulement du câble sur le fût de la bobine n'est pas constitué d'hélices successives parallèles mais forme une série de courbes irrégulières. Dans les bobinoirs connus sur lesquels l'opération d'enroulement est contrôlée constamment par un opérateur, on maintient le brin d'arrivée du câble, désigné par 7, sous un angle convenable appelé l'angle de retard et désigné à la fig. 1 par r. Evidemment, lorsque le dépôt d'une couche de spires est terminé, l'angle du brin 7 par rapport à un plan perpendiculaire à l'axe de la bobine doit être modifié et pendant le dépôt de la dernière spire d'une couche cet angle doit être amené à zéro. Lorsque la première spire de la couche suivante a été formée, il faut ensuite guider le brin 7 du câble de façon que l'angle de retard se renverse, puisque pendant le dépôt d'une couche se formant de gauche à droite, cet angle doit être inversé par rapport à la valeur qu'il a au cours du dépôt d'une couche se formant de droiteâ gauche.However, when it comes to winding large cables it is not possible to control an automatic cutting operation by simply making the speed of the cutting carriage proportional to the speed of rotation of the reel and up to now it was necessary for the cutting operation to be constantly monitored by an operator. To illustrate the mechanical conditions under which the successive turns of the cable are deposited on the drum of the coil, we will first consider fig. 1 which schematically shows a coil 1 on which a cable 2 is being deposited turn by turn. The coil 1 comprises a cylindrical barrel 3 and two end flanges 4 and 5 also called cheeks having the form of discs. The cable 2 is hooked by its end into a hole 6 formed in the barrel 3 of the coil 1. The latter is rotated in the direction of the arrow A, so that a first turn is deposited in contact with the flange 4. However, at the end of the first turn, the cable 2 must make a deflection movement on the left so that the second turn comes to be placed in parallel and in contact with the first. Thus, the winding of the cable on the drum of the coil does not consist of successive parallel helices but forms a series of irregular curves. In known winders on which the winding operation is constantly monitored by an operator, the cable arrival strand, designated by 7, is maintained at a suitable angle called the delay angle and designated in FIG. 1 by r. Obviously, when the deposition of a layer of turns is completed, the angle of the strand 7 relative to a plane perpendicular to the axis of the coil must be modified and during the deposition of the last turn of a layer this angle must be brought to zero. When the first turn of the next layer has been formed, it is then necessary to guide the strand 7 of the cable so that the delay angle is reversed, since during the deposition of a layer forming from left to right, this angle must be inverted with respect to that value during the deposition of a layer forming right an left.

La présente invention a pour but de créer un dispositif de commande automatique d'une opération de trancanage susceptible d'équiper des bobinoirs de grandes dimensions capables de supporter et d'entrai- ner des bobines destinées à recevoir de grandes longueurs de câbles d'un diamètre supérieur à 10 mm.The object of the present invention is to create a device for automatically controlling a cutting operation capable of equipping large winders capable of supporting and driving reels intended to receive long lengths of cables of a diameter greater than 10 mm.

Dans ce but, la présente invention a pour objet un dispositif de commande automatique d'une opération de trancanage, capable de commander la formation d'un enroulement à spires et couches successives par un câble provenant d'une ligne de production ou de traitement, sur le fût d'une bobine auquel le câble est accroché, la bobine étant entraînée en rotation autour de son axe sur un support, et le câble traversant un guide-câble qui est mobile par rapport au support de bobine dans le sens du dit axe et qui guide le câble avec un angle de retard prédéterminé, caractérisé en ce qu'il comporte

  • des moyens d'entraînement réagissant aux dits signaux de commande de manière à provoquer des déplacements relatifs entre le guide-câble et le support de bobine, en fonction du résultat de l'analyse.
To this end, the subject of the present invention is an automatic control device for a cutting operation, capable of controlling the formation of a winding with successive turns and layers by a cable coming from a production or processing line, on the drum of a reel to which the cable is attached, the reel being driven in rotation about its axis on a support, and the cable passing through a cable guide which is movable relative to the reel support in the direction of said axis and which guides the cable with a predetermined delay angle, characterized in that it comprises

On commencera par décrire succinctement l'installation de bobinage représentée aux fig. 2 et 3. Le fût 3 et le flasque gauche 5 de la bobine 1 sont visibles en coupe par un plan perpendiculaire à l'axe de la bobine à la fig. 2. Le flasque 5 est supporté par une pinole 8 (fig. 3) portée elle-même par un palier 9 solidaire du montant gauche 10 du bobinoir. La traverse supérieure 11 du bobinoir (fig. 2) s'étend parallèlement à l'axe de la bobine 1 et guide l'extrémité supérieure du montant 12 qui comporte un palier 13 guidant lui-même une pinole 14 supportant le flasque droit 4 de la bobine 1. Les deux montants 10 et 12 du bobinoir reposent sur des embases 15 et 16, munies de galets 17 qui roulen sur deux rails parallèles 18. Les galets 17 sont liés à des moyens d'entraînement permettant de déplacer l'ensemble du bobinoir en va et vient sur les rails 18, tandis que des moyens d'entraînement de la bobine 1 (non représentés) font tourner l'une des pinoles 8 ou 14 munie d'éléments d'accouplement au flasque correspondant de la bobine. Les moyens d'entraînement de la bobine sont capables de faire tourner cette dernière autour de son axe à une vitesse constante ou variable en fonction de conditions qui peuvent être prédéterminées. Ainsi par exemple, l'entraînement de la bobine peut avoir lieu à couple de résistance constant.We will begin by briefly describing the winding installation shown in FIGS. 2 and 3. The barrel 3 and the left flange 5 of the coil 1 are visible in section through a plane perpendicular to the axis of the coil in FIG. 2. The flange 5 is supported by a pinole 8 (fig. 3) carried itself by a bearing 9 integral with the left upright 10 of the winder. The crossing upper 11 of the winder (fig. 2) extends parallel to the axis of the reel 1 and guides the upper end of the upright 12 which has a bearing 13 itself guiding a pinole 14 supporting the right flange 4 of the reel 1. The two uprights 10 and 12 of the winder rest on bases 15 and 16, provided with rollers 17 which roll on two parallel rails 18. The rollers 17 are linked to drive means making it possible to move the whole of the winder goes back and forth on the rails 18, while means for driving the coil 1 (not shown) rotate one of the pinoles 8 or 14 provided with coupling elements to the corresponding flange of the coil. The drive means of the coil are capable of rotating the latter around its axis at a constant or variable speed depending on conditions which can be predetermined. Thus, for example, the drive of the coil can take place at constant resistance torque.

Devant le bobinoir proprement dit, est placé un support de trancanage qui comporte un montant vertical rigide 19 muni de moyens de guidage représentés au dessin par une gorge à queue d'aronde 20 s'étendant verticalement et apte à guider un bras horizontal 21 qui peut ainsi être déplacé verticalement de haut en bas et de bas en haut sur le montant 19. Ce bras de support 21 présente lui-même dans sa face supérieure une gorge de guidage 22 dans laquelle coulisse un chariot de trancanage 23. Ce dernier porte deux rouleaux cylindriques d'axes verticaux 24 disposés parallèlement l'un à l'autre à une distance telle l'un de l'autre que le brin d'arrivée 7 du câble 2 est guidé étroitement entre ces deux rouleaux. Des moyens d'entraînement non représentés permettent de déplacer le chariot 23 de gauche à droite et de droite à gauche parallèlement à l'axe de la bobine 1 devant cette dernière, le brin 7 du câble étant en outre guidé dans le sens de la hauteur entre deux rouleaux horizontaux 25 également distants l'un de l'autre d'une distance égale au diamètre du câble. Les rouleaux 25 sont supportés à leurs extrémités par des montants 26 qui reposent sur le bras de support 21. Un autre bras de support 27 solidaire du socle horizontal 21 permet de fixer au-dessus de ce socle une caméra 28 dont le principe du système optique est représenté schématiquement à la fig. 4. Cette caméra 28 possède un objectif 29 dont l'axe du système optique est orienté horizontalement et perpendiculairement à l'axe de la bobine 1. Comme le bras 27 est supporté par le socle 21 qui est lui-même mobile en hauteur, la hauteur de l'axe de l'objectif 29 peut être choisie à volonté et comme on le verra plus loin, elle est commandée de façon à ce que cet axe soit tangent à la dernière couche complète de l'enroulement formé sur la bobine 1. Bien entendu, selon les circonstances on peut aussi choisir pour l'axe de l'objectif 29 une direction différente de celle qui vient d'être définie, notamment une direction légèrement inclinée, la règle de la tangence à la dernière couche complète de l'enroulement étant toutefois une règle générale.In front of the winder proper, is placed a cutting support which comprises a rigid vertical upright 19 provided with guide means shown in the drawing by a dovetail groove 20 extending vertically and capable of guiding a horizontal arm 21 which can thus be moved vertically from top to bottom and bottom to top on the upright 19. This support arm 21 itself has in its upper face a guide groove 22 in which slides a cutting carriage 23. The latter carries two rollers cylindrical with vertical axes 24 arranged parallel to one another at such a distance from each other that the strand 7 of the cable 2 is guided closely between these two rollers. Driving means not shown make it possible to move the carriage 23 from left to right and from right to left parallel to the axis of the coil 1 in front of the latter, the strand 7 of the cable being further guided in the direction of height between two horizontal rollers 25 also distant from each other by a distance equal to the diameter of the cable. The rollers 25 are supported at their ends by uprights 26 which rest on the support arm 21. Another support arm 27 secured to the horizontal base 21 makes it possible to fix above this base a camera 28, the principle of the optical system is shown schematically in FIG. 4. This camera 28 has a lens 29 whose axis of the optical system is oriented horizontally and perpendicular to the axis of the coil 1. As the arm 27 is supported by the base 21 which is itself movable in height, the height of the axis of the objective 29 can be chosen at will and as will be seen later, it is controlled so that this axis is tangent to the last complete layer of the winding formed on the coil 1. Of course, depending on the circumstances, it is also possible to choose for the axis of the objective 29 a direction different from that which has just been defined, in particular a slightly inclined direction, the rule of tangency to the last complete layer of winding being however a general rule.

Finalement, l'installation de bobinage décrite comporte une rampe lumineuse 30 disposée verticalement en regard de la caméra 28 mais de l'autre côté de la bobine. On se rend compte que cette rampe lumineuse a pour effet de projeter dans une direction perpendiculaire à l'axe de la bobine l'image de la silhouette de l'enroulement, c.à.d. l'image que l'on obtient si l'on coupe l'enroulement en cours de formation par un plan vertical passant par l'axe de la bobine.Finally, the described winding installation comprises a light ramp 30 arranged vertically opposite the camera 28 but on the other side of the coil. We realize that this light ramp has the effect of projecting in a direction perpendicular to the axis of the coil the image of the silhouette of the winding, i.e. the image that is obtained if the winding being cut is cut by a vertical plane passing through the axis of the coil.

On décrira maintenant le principe de la caméra 28. Il s'agit d'un appareil optique d'un type connu en soi, notamment d'un appareil de la marque Reticon vendu par la société EG. & G. Inc. à Wellesley (Mass. U.S.A). Cet appareil dénommé "système de détection d'images" 29 comporte un objectif du type zoom permettant de varier la distance focale et le grossissement de l'appareil. L'image formée par l'objectif est réfléchie par un miroir à 45° 31 et projetée en image réelle sur une surface de réception 33. Cette surface de réception 33 est matérialisée par une grille 34 qui dans la forme d'exécution décrite, est carrée et constituée par une série de cellules photo-détectrices. Ces cellules, par exemple des diodes photosensibles sont connectées dans un circuit matérialisé par un micro-processeur MP. Dans la forme d'exécution décrite on a trouvé qu'une grille 34 formée de 1024 cellules réparties sur un carré de 32 cellules de côté permettait une détection suffisamment fine pour répondre aux conditions de fonctionnement. En effet, la rampe 30 projette sur l'objectif 29 l'ombre de la silhouette de l'enroulement. L'objectif 29 permet lui-même de choisir la grandeur de la zone de l'enroulement qui sera projetée sur la grille 34 et on a constaté en particulier qu'un grossissement tel que la zone de l'enroulement qui est projetée sur la grille 34 a l'allure représentée à la fig.5, était un grossissement convenable. A cette figure 5 on voit sur la grille 34 formée de 1024 cellules photodétectrices l'image de la silhouette d'une partie de l'enroulement comportant quatre spires de câbles désignées par A, B. C et D et faisant partie de la dernière couche complète déposée sur la bobine et l'image des deux dernières spires E et F de la couche en cours de formation, la spire F étant une spire partielle et la disposition géométrique étant telle que la partie de la silhouette désignée par F représente l'endroit où le brin 7 du câble 2 vient précisément se déposer sur l'enroulement. On constate que les cellules sont ajustées de façon que leur état (conducteur ou non conducteur) change selon qu'elles sont exposées au rayonnement de la rampe 30 où que, . pour elles, la rampe 30 est masquée par l'enroulement. De préférence, les 1024 cellules seront réparties en séries correspondant chacune à une colonne de sorte que par une commutation convenable du circuit électronique MP on pourra, à chaque instant, effectuer une opération de balayage au cours de laquelle tous les éléments détecteurs de la grille 34 seront explorés successivement, par exemple par colonnes successives. Cette exploration donnera naissance à un signal électrique composé d'une suite d'impulsions en code binaire donnant pour chaque élément de la grille 34 son état éclairé ou caché. De préférence, les photos-diodes de la grille 34 seront explorées par séries successives, chaque série étant composée par les éléments d'une même colonne.The principle of the camera 28 will now be described. It is an optical device of a type known per se, in particular a device of the brand Reticon sold by the company EG. & G. Inc. in Wellesley (Mass. USA). This camera called "image detection system" 29 includes a zoom type lens for varying the focal length and the magnification of the camera. The image formed by the objective is reflected by a 45 ° mirror 31 and projected as a real image onto a reception surface 33. This reception surface 33 is materialized by a grid 34 which, in the embodiment described, is square and made up of a series of photodetector cells. These cells, for example photosensitive diodes are connected in a circuit materialized by a microprocessor MP. In the embodiment described, it has been found that a grid 34 formed of 1024 cells distributed over a square of 32 cells on the side allows detection sufficiently fine to meet the operating conditions. Indeed, the ramp 30 projects onto the objective 29 the shadow of the winding silhouette. The objective 29 itself makes it possible to choose the size of the area of the winding which will be projected onto the grid 34 and it has been observed in particular that a magnification such as the area of the winding which is projected onto the grid 34 at the pace shown in fig.5, was a suitable magnification. In this FIG. 5, we see on the grid 34 formed of 1024 photodetector cells the image of the silhouette of a part of the winding comprising four turns of cables designated by A, B. C and D and forming part of the last layer complete deposited on the reel and the image of the last two turns E and F of the layer being formed, the turn F being a partial turn and the geometrical arrangement being such that the part of the silhouette designated by F represents the place where the strand 7 of the cable 2 is precisely deposited on the winding. It can be seen that the cells are adjusted so that their state (conductive or non-conductive) changes depending on whether they are exposed to the radiation from the ramp 30, where, . for them, the ramp 30 is masked by the winding. Preferably, the 1024 cells will be divided into series each corresponding to a column so that by suitable switching of the electronic circuit MP, it will be possible, at any time, to perform a scanning operation during which all of the detector elements of the grid 34 will be explored successively, for example by successive columns. This exploration will give rise to an electrical signal composed of a series of pulses in binary code giving for each element of the grid 34 its lit or hidden state. Preferably, the photo-diodes of the grid 34 will be explored in successive series, each series being composed of the elements of the same column.

La fig. 5 donne à titre d'exemple le résultat d'une telle Exploration. Sur cette figure, les 1024 éléments photo-détecteurs de la grille 34 sont représentés sous forme d'une matrice carrée numérotée par lignes et par colonnes. Chacun de ces éléments est désigné par le chiffre 35. L'image de la silhouette d'une zone prédéterminée de l'enroulement telle qu'elle apparaît sur cette grille est clairement représentée à cette fig. 5. La silhouette de deux spires A et B de la dernière couche complète déposée sur l'enroulement est clairement visible dans la partie de gauche de l'image de même qu'une partie de la silhouette d'une spire C appartenant à la même couche. Une quatrième spire D de la dernière couche complète est entièrement noyée dans la partie de l'image pour laquelle les éléments sont à l'état masqué. Au-dessus de cette couche complète on voit apparaître deux spires E et F de la couche en cours de formation. Telle qu'elle est visible au dessin, cette couche en formation se forme par spires successives allant de droite à gauche, bien que ceci puisse correspondre en réalité à une couche se formant de gauche à droite par suite du renversement de l'image.Fig. 5 gives by way of example the result of such an exploration. In this figure, the 1024 photo-detector elements of the grid 34 are represented in the form of a square matrix numbered by lines and by columns. Each of these elements is designated by the number 35. The image of the silhouette of a predetermined area of the winding as it appears on this grid is clearly represented in this fig. 5. The silhouette of two turns A and B of the last complete layer deposited on the winding is clearly visible in the left part of the image as well as part of the silhouette of a turn C belonging to the same layer. A fourth turn D of the last complete layer is completely embedded in the part of the image for which the elements are in the masked state. Above this complete layer, two turns E and F of the layer being formed appear. As visible in the drawing, this layer in formation is formed by successive turns going from right to left, although this may actually correspond to a layer forming from left to right as a result of the reversal of the image.
