Description

La présente invention concerne une machine et un procédé de bobinage d'éléments plats et souples arrivant en continu et se recouvrant partiellement, tels que des feuilles ou des enveloppes imprimées, pour les stocker et les transporter en attendant une opération de débobinage par un autre appareil utilisant ces éléments.The present invention relates to a machine and a method of winding flat and flexible elements arriving continuously and partially overlapping, such as sheets or printed envelopes, for storing and transporting them while waiting for unwinding operation by another apparatus using these elements.

Les bobines de stockage comporte un tambour central possédant un moyeu inséré dans la machine de bobinage et une partie périphérique extérieure cylindrique sur laquelle s'enroule en spirale un flux continu d'éléments plats alignés suivant l'axe longitudinal de défilement et se recouvrant partiellement. Une bande souple fixée par une extrémité en un point médian du tambour vient s'enrouler en même temps que les éléments plats, de manière à marquer une séparation entre les différentes couches d'enroulement et à les serrer sur le tambour pour maintenir l'ensemble en position. Les éléments plats proviennent généralement d'une machine à imprimer en continu et sont mis en bobine pour être stockés dès la sortie de cette machine.The storage reels comprise a central drum having a hub inserted in the winding machine and a cylindrical outer circumferential part on which spirals a continuous flow of flat elements aligned along the longitudinal axis of movement and partially overlapping. A flexible band attached at one end to a mid-point of the drum is wound together with the flat elements, so as to mark a separation between the different winding layers and to tighten them on the drum to hold the assembly together. in position. The flat elements generally come from a continuous printing machine and are reeled to be stored right out of the machine.

Les bobines sont ensuite livrées à l'atelier suivant, qui par exemple confectionne des revues en assemblant différentes feuilles provenant de plusieurs bobines ou effectue une mise sous pli en automatique de documents en les insérant dans des enveloppes provenant d'une bobine. Pour cela, la bobine est débobinée pour extraire les éléments plats, simultanément la bande se déroule et est stockée provisoirement sur un moyeu. Une fois la bobine vide, la bande est remise sur le tambour en l'enroulant dessus, puis l'ensemble est retourné à l'atelier de départ pour servir à nouveau.The reels are then delivered to the next workshop, which for example makes journals by assembling different sheets from multiple reels or automatically envelops documents by inserting them into envelopes from a reel. For this, the reel is unwound to extract the flat elements, simultaneously the tape is unrolled and is stored temporarily on a hub. Once the reel is empty, the tape is put back on the drum by winding it on, then the whole is returned to the starting shop to serve again.

Un inconvénient principal de ce système (voir EP 0 826 616 A1 ) est que pour les tambours revenant des ateliers se trouvant chez différents clients, la bande peut avoir été enroulée de manière très inégale, et après divers manutentions pour le transport au cours desquelles la bobine peut subir des chocs, la bande souple est plus au moins décalée par rapport au plan médian transversal du tambour.A major disadvantage of this system (see EP 0 826 616 A1 ) is that for the drums returning from the workshops at different customers, the band may have been wound very unequally, and after various handling for transport during which the coil may suffer shocks, the band flexible is more or less offset from the transverse median plane of the drum.

Lors du bobinage suivant, la bande souple n'étant pas parfaitement centrée sur toute sa longueur par rapport aux éléments plats, la bobine est alors déformée.During the next winding, the flexible band is not perfectly centered over its entire length relative to the flat elements, the coil is then deformed.

En effet, la bobine étant constituée d'un empilage d'éléments souples et la bande assurant un serrage ne couvrant qu'une partie centrale de l'élément plat, les parties latérales non maintenues sont déformées. Si la bande se déporte latéralement au cours du bobinage, la déformation des éléments plats est irrégulière ce qui peut poser des problèmes ensuite pour les machines automatiques situées en aval qui n'arrivent alors pas à saisir les éléments.Indeed, the coil consisting of a stack of flexible elements and the band ensuring a clamping covering only a central portion of the flat member, the non-maintained side portions are deformed. If the band moves laterally during winding, the deformation of the flat elements is irregular, which can cause problems for downstream automatic machines that can not then grasp the elements.

De plus, la géométrie de la bobine est aussi dans ce cas mauvaise avec des faces latérales déformées qui ne sont plus plates. Ce problème, surtout dans le cas où il se conjugue avec une tension de bande mal appropriée au cours du bobinage, peut conduire à un décalage axial du tambour ou d'une partie de la bobine lors d'une manutention pouvant entraîner l'écroulement complet de la bobine.In addition, the geometry of the coil is also in this case bad with deformed side faces that are no longer flat. This problem, especially in the case where it is combined with an improperly adapted tape tension during winding, can lead to an axial shift of the drum or part of the bobbin during handling which may lead to complete collapse. of the coil.

La présente invention a notamment pour but d'éviter ces inconvénients et d'apporter à la réalisation d'une machine de bobinage une solution simple efficace, permettant de garantir une bonne qualité d'enroulement des bobines.The present invention is intended in particular to avoid these disadvantages and to provide the realization of a winding machine a simple effective solution, to ensure a good winding quality of the coils.

Elle propose à cet effet une machine de bobinage comprenant : d'une part un ensemble de bobinage recevant un flux continu d'éléments plats et souples alignés suivant un axe longitudinal et se recouvrant partiellement, pour former une bobine en enroulant en spirale autour d'un tambour ces éléments avec interposition entre les spires d'une bande centrale souple dont une extrémité est fixée sur le tambour, et d'autre part un ensemble de déroulage de ladite bande souple dont l'autre extrémité se déroule simultanément à partir d'un moyeu sur lequel la bande a été préalablement enroulée, un dispositif de freinage étant prévu sur le moyeu pour assurer une tension continue de la bande. De manière caractéristique, la machine comporte de plus un moyen motorisé de réglage de la position transversale du moyeu assurant un déplacement latéral par rapport à la bobine pour garder un alignement constant de la bande au cours du bobinage.It proposes for this purpose a winding machine comprising: on the one hand a winding assembly receiving a continuous flow of flat and flexible elements aligned along a longitudinal axis and partially overlapping, to form a coil by spiraling around a drum these elements with interposition between the turns of a flexible central band whose one end is fixed on the drum, and secondly a peeling assembly of said flexible band whose other end is simultaneously running from a hub on which the strip was previously rolled up, a braking device being provided on the hub to ensure a DC voltage of the band. Typically, the machine further comprises a motorized means for adjusting the transverse position of the hub providing lateral displacement relative to the coil to keep a constant alignment of the band during winding.

Un avantage essentiel de la machine de bobinage selon l'invention est que la position transversale de la bande étant rigoureusement assurée par le moyen motorisé, la bande enroulée se trouve bien alignée sur un même plan et dans l'axe des éléments plats ce qui assure à ces éléments une déformation uniforme et à la bobine une bonne symétrie.An essential advantage of the winding machine according to the invention is that the transverse position of the strip being strictly ensured by the motorized means, the wound strip is well aligned on the same plane and in the axis of the flat elements which ensures to these elements a uniform deformation and to the coil a good symmetry.

De plus, le moyen de réglage étant motorisé, il peut être très réactif et assurer une bonne position dès le début du bobinage pour tous les types de défauts d'enroulement constatés sur les tambours revenant vides avec leur bande enroulée dessus.In addition, the adjustment means being motorized, it can be very responsive and ensure a good position from the beginning of the winding for all types of winding defects found on drums returning empty with their band wound on it.

Selon un mode préféré de l'invention, le moyeu est fixé sur un arbre supporté par un chariot monté sur un moyen de guidage permettant un mouvement transversal par rapport à un châssis de l'ensemble de déroulage.According to a preferred embodiment of the invention, the hub is fixed on a shaft supported by a carriage mounted on a guide means allowing transverse movement relative to a frame of the unwinding assembly.

De préférence, le moyen motorisé est un vérin électrique comportant une vis à billes et un écrou, lié d'une part au châssis et d'autre part au chariot, réalisant un positionnement transversal de l'un par rapport à l'autre.Preferably, the motorized means is an electric jack comprising a ball screw and a nut, connected on the one hand to the frame and on the other hand to the carriage, performing a transverse positioning of one with respect to the other.

Avantageusement, le moyen motorisé de réglage de la position transversale du moyeu par rapport à la bobine utilise pour commander son mouvement au cours du bobinage un capteur fixe par rapport à un châssis de l'ensemble de déroulage donnant une information sur la position latérale de la bande en un endroit situé à proximité du point de déroulement de la bande du moyeu.Advantageously, the motorized means for adjusting the transverse position of the hub relative to the coil uses to control its movement during winding a fixed sensor relative to a frame of the unwinding assembly giving information on the lateral position of the strip at a location near the unwinding point of the hub strip.

De préférence, le moyen motorisé de réglage de la position transversale du moyeu est utilisé pour aligner latéralement la bande sur le moyeu au cours d'une opération préalable d'enroulement de la bande sur le moyeu à partir du tambour.Preferably, the motorized means for adjusting the transverse position of the hub is used to laterally align the strip on the hub during a prior operation of winding the strip on the hub from the drum.

L'alignement latéral de la bande par rapport au moyeu lors de l'opération préalable d'enroulement sur ce moyeu peut utiliser un capteur fixe par rapport au chariot donnant une information sur la position latérale de la bande en un endroit situé à proximité du point d'enroulement de la bande sur le moyeu.The lateral alignment of the band with respect to the hub during the prior winding operation on this hub can use a fixed sensor relative to the carriage providing information on the lateral position of the web at a location near the winding point of the web on the hub.

Le capteur donnant une information sur la position latérale de la bande peut être un capteur optique.The sensor giving information on the lateral position of the strip may be an optical sensor.

Suivant un mode de réalisation préféré, le dispositif de freinage comprend une machine électrique rotative pilotée par une commande pour délivrer un couple de freinage ou un couple moteur.According to a preferred embodiment, the braking device comprises a rotary electric machine controlled by a control for delivering a braking torque or a motor torque.

L'entraînement de la courroie du convoyeur alimentant le flux d'éléments plats peut se faire par un appui tangentiel de cette courroie sur la périphérie extérieure de la bobine, et un capteur peut donner une indication sur le mouvement de la courroie et sur le sens de ce mouvement pour commander la machine électrique et fournir soit un couple de freinage si la bobineuse est en cours de bobinage, soit un couple moteur si la bobineuse tourne dans l'autre sens pour une opération préalable d'enroulement de la bande sur le moyeu.The belt drive of the conveyor feeding the flow of flat elements can be done by a tangential support of this belt on the outer periphery of the coil, and a sensor can give an indication of the movement of the belt and the direction of this movement to control the electric machine and provide either a braking torque if the winder is being wound, or a motor torque if the winder rotates in the other direction for a prior operation of winding the band on the hub .

De préférence, la traction sur la bande réalisée par le couple de freinage délivré par la machine électrique est régulièrement décroissante au cours d'une opération de bobinage.Preferably, the traction on the belt produced by the braking torque delivered by the electric machine is regularly decreasing during a winding operation.

La décroissance de la traction sur la bande au cours d'une opération de bobinage peut être commandée par un capteur donnant une information sur le diamètre externe de la bobine en cours de bobinage.The decrease of the traction on the web during a winding operation can be controlled by a sensor giving information on the outer diameter of the coil being wound.

Dans un mode de réalisation, la décroissance de la traction sur la bande entre le début et la fin du bobinage se fait dans un rapport compris entre deux et quatre.In one embodiment, the decay of the traction on the web between the beginning and the end of the winding is in a ratio of between two and four.

Suivant une utilisation intéressante de l'invention, les éléments plats enroulés sur la bobine sont des enveloppes. Elles peuvent avoir une largeur plus grande que la hauteur et être disposées transversalement par rapport au flux suivant la largeur.According to an interesting use of the invention, the flat elements wound on the coil are envelopes. They may have a width greater than the height and be arranged transversely with respect to the flow along the width.

En particulier, les enveloppes bobinées ont une largeur d'environ 19 à 24 centimètres et une hauteur d'environ 11 à 18 centimètres, et la tension de la bande est de l'ordre de 300 Newton au début du bobinage et de 100 Newton à la fin.In particular, the wound envelopes have a width of about 19 to 24 centimeters and a height of about 11 to 18 centimeters, and the tension the band is of the order of 300 Newton at the beginning of the winding and 100 Newton at the end.

Avantageusement, les bobines d'enveloppes réalisées sont utilisées en aval par une machine de mise sous pli automatique qui déroule ces bobines pour en extraire une à une les enveloppes et y insérer automatiquement un courrier.Advantageously, the envelopes of envelopes made are used downstream by an automatic enveloping machine which unrolls these coils to extract one from the envelopes and automatically insert a mail.

Selon un autre aspect, l'invention se rapporte également à un procédé de bobinage d'une bobine à partir d'un flux continu d'éléments plats et souples qui sont alignés suivant un axe longitudinal et se recouvrent partiellement.According to another aspect, the invention also relates to a method of winding a coil from a continuous flow of flat and flexible elements which are aligned along a longitudinal axis and overlap partially.

Le bobinage est obtenu par enroulement de ces éléments plats en spirale autour d'un tambour avec interposition entre les spires d'une bande centrale souple qui se déroule à partir d'un moyeu.The winding is obtained by winding these flat elements spirally around a drum with interposition between the turns of a flexible central strip which is unwound from a hub.

De façon caractéristique, on réalise en permanence pendant l'enroulement un contrôle de la position latérale de la bande centrale souple enroulée autour dudit tambour (8), pour modifier la position transversale du moyeu en fonction du résultat de ce contrôle.Characteristically, a control of the lateral position of the flexible central strip wound around said drum (8) is constantly made during winding to modify the transverse position of the hub as a function of the result of this check.

De préférence, ce contrôle de la position latérale de la bande centrale souple est réalisé par des moyens de contrôles, éventuellement optiques, reliés à un moyen motorisé, éventuellement de type vérin motorisé, de réglage de la position transversale du moyeu.Preferably, this control of the lateral position of the flexible central strip is achieved by control means, possibly optical, connected to a motorized means, possibly motorized jack type, for adjusting the transverse position of the hub.

De préférence encore, le contrôle de la position latérale de la bande centrale souple détermine le décalage entre cette position latérale de la bande centrale souple et l'axe du tambour.More preferably, the control of the lateral position of the flexible central strip determines the offset between this lateral position of the flexible central strip and the axis of the drum.

La position transversale du moyeu est alors modifiée en sorte de supprimer ce décalage.The transverse position of the hub is then modified so as to eliminate this offset.

Eventuellement, préalablement à l'enroulement des éléments plats en spirale autour du tambour avec interposition entre les spires de la bande centrale souple, cette dernière est amenée depuis un tambour et enroulée autour du moyeu.Optionally, prior to winding the flat spiral elements around the drum with interposition between the turns of the flexible central strip, the latter is fed from a drum and wound around the hub.

Dans ce cas, on réalise en permanence pendant l'enroulement de la bande centrale souple au tour du moyeu un contrôle de la position latérale de cette bande centrale souple enroulée autour dudit moyeu, et la position transversale de ce moyeu est modifiée en fonction du résultat de ce contrôle.In this case, a continuous control of the lateral position of this flexible central strip wound around said hub is continuously carried out during the winding of the flexible central band around the hub, and the transverse position of this hub is modified as a function of the result. of this control.

De préférence, le contrôle de la position latérale de la bande centrale souple enroulée autour du moyeu est réalisé par des moyens de contrôles, par exemple optiques, reliés à un moyen motorisé, par exemple de type vérin motorisé, de réglage de la position transversale du moyeu.Preferably, the control of the lateral position of the flexible central strip wound around the hub is carried out by control means, for example optical, connected to a motorized means, for example of motorized jack type, for adjusting the transverse position of the hub. hub.

De préférence encore, le contrôle de la position latérale de la bande centrale souple enroulée autour du moyeu détermine le décalage entre cette position latérale de la bande centrale souple et l'axe du moyeu.More preferably, the control of the lateral position of the flexible central strip wound around the hub determines the offset between this lateral position of the flexible central strip and the axis of the hub.

La position transversale du moyeu est alors modifiée en sorte de supprimer ce décalage.The transverse position of the hub is then modified so as to eliminate this offset.

Eventuellement, on réalise en permanence, pendant l'enroulement des éléments plats en spirale autour du tambour, un réglage de la tension de la bande centrale souple à chaque formation de spire.Optionally, during the winding of the flat spiral elements around the drum, an adjustment of the tension of the flexible central strip is carried out continuously at each turn formation.

De préférence, le réglage de cette tension de la bande centrale souple est obtenu par réglage de la vitesse de déroulement de cette bande centrale souple à partir du moyeu.Preferably, the adjustment of this tension of the flexible central strip is obtained by adjusting the unwinding speed of this flexible central strip from the hub.

De préférence encore, la vitesse de déroulement de la bande centrale souple à partir du moyeu diminue, éventuellement linéairement, aux fur et à mesure que le diamètre de la bobine augmente.More preferably, the unwinding speed of the flexible central strip from the hub decreases, possibly linearly, as the diameter of the coil increases.

La diminution de la vitesse de déroulement de la bande centrale souple à partir du moyeu peut être obtenue par un dispositif de freinage prévu sur ce moyeu (60) et relié à un moyen de contrôle, de préférence de type capteur à ultrasons, de la hauteur de l'axe de la bobine.The decrease in the unwinding speed of the flexible central strip from the hub can be obtained by a braking device provided on this hub (60) and connected to a control means, preferably of ultrasonic sensor type, of the height of the axis of the coil.

L'invention sera mieux comprise et d'autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description ci-après donnée à titre d'exemple en référence aux dessins annexés dans lesquels :

  • la figure 1 représente une vue de face d'une machine de bobinage suivant l'invention ;
  • la figure 2 représente une vue en perspective d'une partie de la machine de bobinage comportant le dispositif de déroulement d'un moyeu.
The invention will be better understood and other features and advantages will appear more clearly on reading the following description given by way of example with reference to the accompanying drawings in which:
  • the figure 1 represents a front view of a winding machine according to the invention;
  • the figure 2 is a perspective view of a portion of the winding machine having the unwinding device of a hub.

La figure 1 représente une machine de bobinage 1 comportant un ensemble de bobinage ou bobineuse 2 d'éléments plats et souple 10 et un ensemble de déroulage 4 d'une bande souple 26. Les éléments plats 10 sortent d'une machine de fabrication qui par exemple à partir d'une bande continue de papier imprimé, découpe, pli, encolle et assemble des éléments comme des enveloppes. La bobine 6 comporte en son centre un tambour 8 sur lequel sont bobinés les éléments plats 10, le moyeu du tambour est maintenu par un système de pince 30 permettant un montage rapide sur un axe rotatif porté par le châssis 16 de l'ensemble 2, et est entraîné en rotation par un moteur de bobinage.The figure 1 represents a winding machine 1 comprising a set of winding or winding 2 of flat and flexible elements 10 and a set of unwinding 4 of a flexible band 26. The flat elements 10 come out of a manufacturing machine which for example from a continuous strip of printed paper, cut, fold, glue and assemble elements such as envelopes. The coil 6 comprises at its center a drum 8 on which are wound the flat elements 10, the hub of the drum is held by a clamp system 30 for rapid mounting on a rotary shaft carried by the frame 16 of the assembly 2, and is rotated by a winding motor.

Une extrémité d'une bande souple 26 est fixée sur le tambour 8 de manière à pouvoir s'enrouler dessus suivant un plan transversal sensiblement centré au milieu du tambour.One end of a flexible band 26 is fixed on the drum 8 so as to be able to wind on a transverse plane substantially centered in the middle of the drum.

Les éléments 10 arrivent alignés suivant l'axe du flux en se chevauchant les uns sur les autres, sur un convoyeur 12 constitué de deux courroies parallèles disposées de part et d'autre de l'axe longitudinal. Le convoyeur 12 n'a pas de motorisation propre, les courroies sont toujours en appui tangentiel sur la périphérie extérieure de la bobine 6 et sont entraînées par contact, ce qui permet d'assurer en permanence une parfaite synchronisation de la vitesse d'avance du convoyer 12 avec la vitesse périphérique de la bobine 6, sans frottement. Le maintien de l'état et de la position des éléments plats 10 est ainsi garanti.The elements 10 arrive aligned along the axis of the flow overlapping each other on a conveyor 12 consisting of two parallel belts disposed on either side of the longitudinal axis. The conveyor 12 does not have its own motorization, the belts are always in tangential bearing on the outer periphery of the spool 6 and are driven by contact, which makes it possible to permanently ensure a perfect synchronization of the feed speed of the machine. convey 12 with the peripheral speed of the coil 6, without friction. Maintaining the state and position of the flat elements 10 is thus guaranteed.

Près du point de tangence avec la bobine 6, la bande souple 26 tractée par la bobine et maintenue sous tension par l'ensemble de déroulage 4 comportant un frein vient s'insérer entre les deux courroies du convoyeur 12 pour plaquer le flux d'éléments plats 10 sur la périphérie de la bobine. Ces éléments se trouvent enroulés en spirale, chaque spire étant séparée de la suivante par la bande 26 qui tient le tout serré de manière continue.Near the point of tangency with the coil 6, the flexible strip 26 pulled by the coil and kept under tension by the unwinding assembly 4 comprising a brake is inserted between the two belts of the conveyor 12 to press the flow of elements. plates 10 on the periphery of the coil. These elements are wound spirally, each turn being separated from the next by the strip 26 which holds the whole thing in a continuous manner.

L'axe du tambour 8 de la bobine 6 est fixé au châssis 16 de l'ensemble de bobinage 2 par des rails de guidage 14 de manière à pouvoir coulisser verticalement sous l'action d'un moteur 18. La bande souple 26 provenant de l'ensemble de déroulage 4 passe derrière un galet 28 monté libre en rotation au bout d'un bras 22 pivotant autour d'un axe 24. Le galet 28 permet de régulariser la tension de la bande 26, il permet aussi de suivre la croissance du diamètre de la bobine 6, un capteur mesure le basculement du bras au fur et à mesure de l'enroulement d'éléments plats 10 et commande après un certain déplacement la montée de l'axe de rotation de la bobine 6 suivant une hauteur incrémentale prédéterminée.The axis of the drum 8 of the spool 6 is fixed to the frame 16 of the winding assembly 2 by guide rails 14 so as to be able to slide vertically under the action of a motor 18. The flexible strip 26 coming from the unwinding assembly 4 passes behind a roller 28 mounted free to rotate at the end of an arm 22 pivoting about an axis 24. The roller 28 serves to regulate the tension of the strip 26, it also makes it possible to follow the growth of the diameter of the coil 6, a sensor measures the tilting of the arm as and when the winding of flat elements 10 and control after a certain displacement the rise of the axis of rotation of the coil 6 according to an incremental height predetermined.

La figure 2 présente l'ensemble de déroulage 4 comportant un châssis 40 fixe par rapport à l'ensemble de bobinage 2, recevant sur sa partie supérieure un chariot 42 mobile transversalement. Le chariot 42 comporte sur sa face inférieure deux jeux de deux patins de guidage 44 espacés, chaque jeu coulisse sur un rail 46 lié au châssis 40 pour assurer un guidage précis.The figure 2 presents the unwinding assembly 4 comprising a frame 40 fixed relative to the winding assembly 2, receiving on its upper part a carriage 42 movable transversely. The carriage 42 has on its underside two sets of two spaced apart guide shoes 44, each set slides on a rail 46 connected to the frame 40 to provide precise guidance.

Un motoréducteur 48 est fixé sur le dessus du chariot 42, une poulie se trouvant à son extrémité reçoit une courroie crantée 50 qui entraîne une deuxième poulie fixée sur un arbre 52 supporté par deux paliers se trouvant dans le châssis 40. Un moyeu 60 placé entre les paliers est porté par l'arbre 52, il comporte sur sa périphérie une succession de pastilles aimantées recevant une pièce métallique fixée à l'extrémité de la bande souple 26 pour démarrer son enroulement.A geared motor 48 is fixed on top of the carriage 42, a pulley at its end receives a toothed belt 50 which drives a second pulley fixed on a shaft 52 supported by two bearings in the frame 40. A hub 60 placed between the bearings is carried by the shaft 52, it has on its periphery a succession of magnetic pellets receiving a metal part fixed to the end of the flexible band 26 to start winding.

Par ailleurs, la position latérale du chariot 42 est commandée par un vérin électrique 54 constitué d'une vis entraînée par un moteur électrique qui fait coulisser axialement un écrou par l'intermédiaire de billes assurant un fonctionnement sans jeu ni frottement. Ce vérin 54 prend appui d'une part sur un support 56 lié au chariot 42 et d'autre part sur un support 58 lié au châssis 40, il permet de régler avec rapidité et précision la position latérale du chariot et donc du moyeu 60.Furthermore, the lateral position of the carriage 42 is controlled by an electric jack 54 consisting of a screw driven by an electric motor which slides axially a nut through balls ensuring operation without play or friction. This jack 54 is supported on the one hand on a support 56 connected to the carriage 42 and on the other hand on a support 58 connected to the frame 40, it allows to adjust quickly and accurately the lateral position of the carriage and therefore the hub 60.

Ce réglage se fait à partir du signal donné par deux capteurs optiques 62, 64 et d'une roue codeuse 66. Les capteurs optiques sont fixés l'un 62 au chariot 42 et l'autre 64 au châssis 40, à proximité du point d'enroulement de la bande 26 sur le moyeu 60 et donnent un signal en fonction de la position latérale de la bande 26. La roue codeuse 66 est entraînée en rotation par la courroie 12 et donne un signal indiquant la rotation de la bobine ainsi que le sens de rotation.This adjustment is made from the signal given by two optical sensors 62, 64 and a coding wheel 66. The optical sensors are fixed one to the carriage 42 and the other 64 to the frame 40, near the point d winding of the band 26 on the hub 60 and give a signal as a function of the lateral position of the band 26. The encoder wheel 66 is rotated by the belt 12 and gives a signal indicating the rotation of the bobbin and the sense of rotation.

Le fonctionnement de la machine de bobinage est le suivant. Pendant qu'une bobine est en cours de bobinage sur un premier ensemble de bobinage, une seconde bobine 6 disposée sur un second ensemble de bobinage est préparée pour prendre la relève. Un tambour 8 comportant une bande 26 enroulée dessus est fixé par les pinces 30 à l'axe de la bobineuse, l'extrémité libre de la bande est guidée vers le moyeu 60 par une courroie non représentée, puis fixée au moyeu par les aimants disposés dessus. Le motoréducteur 48 enroule alors la bande sur le moyeu 60 pendant que le capteur 62 fixé au chariot 42 est utilisé pour piloter par l'intérmédiaire d'une commande le vérin 54 et déplacer latéralement le chariot 44 de manière à compenser les défauts d'alignement de la bande 26 enroulée sur le tambour 8, en alignant à tout moment le moyeu 60 suivant la position latérale de la bande.The operation of the winding machine is as follows. While a coil is being wound on a first coil assembly, a second coil 6 disposed on a second coil assembly is prepared to take over. A drum 8 having a strip 26 wound on it is fixed by the clamps 30 to the axis of the winder, the free end of the strip is guided towards the hub 60 by a not shown belt, and then fixed to the hub by the magnets arranged above. The geared motor 48 then wraps the band on the hub 60 while the sensor 62 attached to the carriage 42 is used to control the actuator 54 via a control and laterally move the carriage 44 so as to compensate for misalignments of the strip 26 wound on the drum 8, aligning at all times the hub 60 according to the lateral position of the strip.

De préférence, le capteur 62 est un capteur optique sans contact et sans usure, qui envoie un faisceau lumineux perpendiculairement à la bande et à cheval sur un des bords. En fonction de l'intensité lumineuse passant sur le côté de la bande, on en déduit sa position plus ou moins décalée latéralement.Preferably, the sensor 62 is a non-contact and wear-free optical sensor, which sends a light beam perpendicular to the band and straddles one of the edges. As a function of the light intensity passing on the side of the strip, it deduces its position more or less offset laterally.

La bande 28 entièrement disposée sur le moyeu 60, cette bobineuse 2 est prête à démarrer ce qui se produit automatiquement lorsque l'autre bobine est pleine, un système d'aiguillage dirigeant automatiquement le flux d'éléments plats 10 vers cette nouvelle bobine 6. Le tambour 8 est mis en rotation entraînant le convoyeur 12, ce mouvement avec son sens de déplacement est enregistré par la roue codeuse 66 ce qui met en oeuvre le motoréducteur 48 agissant alors comme un générateur électrique produisant un couple de freinage réalisant la tension de la bande 26. La commande de ce motoréducteur 48 permet, en ajustant la puissance électrique produite de régler simplement, de manière précise et constante dans le temps, le couple de freinage, ce qui est difficile à réaliser avec un freinage mécanique comportant des garnitures de frottement s'échauffant et s'usant en faisant varier le coefficient de frottement.The band 28 fully disposed on the hub 60, this winder 2 is ready to start which occurs automatically when the other coil is full, a referral system automatically directing the flow of flat elements 10 to this new coil 6. The drum 8 is rotated driving the conveyor 12, this movement with its direction of movement is recorded by the encoder wheel 66 which implements the geared motor 48 then acting as an electric generator producing a braking torque realizing the tension of the band 26. The control of this geared motor 48 makes it possible, by adjusting the electrical power produced to simply adjust, precisely and constantly over time, the torque braking, which is difficult to achieve with a mechanical braking comprising friction linings that heat up and wear by varying the coefficient of friction.

Pour le bobinage, le guidage latéral du chariot 42 est à nouveau mis en oeuvre en utilisant le signal du capteur 64 fixé au châssis 40 pour commander le vérin 54 de manière à aligner en permanence la bande 26 sortant du moyeu 60 par rapport à l'axe du tambour 8 qui est lui-même latéralement fixe par rapport au châssis.For winding, the lateral guidance of the carriage 42 is again implemented by using the signal from the sensor 64 fixed to the frame 40 to control the jack 54 so as to permanently align the strip 26 coming out of the hub 60 with respect to the drum axis 8 which is itself laterally fixed relative to the frame.

Par ce procédé de réglage latéral motorisé réalisé successivement lors de l'enroulage de la bande 26 sur le moyeu 60 puis du bobinage des éléments plats 10, les essais ont montrés que quelque soit l'état de l'enroulement de la bande 26 sur le tambour 8, même dans le cas où la bande oscille latéralement sur toute la largeur de ce tambour, les deux réglages successifs de l'alignement fournissent un parfait alignement dès le départ de la bobine et une déformation régulière des éléments plats 10 bobinés, alors que par un dispositif purement statique comportant par exemple des rouleaux de tension bombés ou des galets de guidage latéraux, il faut réaliser successivement plusieurs déroulement de la bande vers le moyeu puis enroulement sur le tambour à vide pour parvenir progressivement à rétablir l'alignement.By this motorized lateral adjustment method successively achieved during the winding of the strip 26 on the hub 60 and then the winding of the flat elements 10, the tests have shown that whatever the state of the winding of the strip 26 on the drum 8, even in the case where the strip oscillates laterally over the entire width of this drum, the two successive adjustments of the alignment provide a perfect alignment from the start of the coil and a regular deformation of the wound flat elements, while by a purely static device comprising for example curved tension rollers or lateral guide rollers, it is necessary to successively carry out several unwinding of the strip towards the hub and then winding on the vacuum drum to progressively restore the alignment.

Ceci est particulièrement important pour des éléments plats 10 ayant une grande largeur et une faible hauteur, par exemple pour des enveloppes dites commerciales ayant un format d'environ 19 à 24 centimètres de largeur par 11 à 18 centimètres de hauteur, et disposées transversalement par rapport au flux suivant la largeur, car le maintien par la bande s'exerçant sur une faible hauteur ne procure pas une grande stabilité du produit. Ces enveloppes sont de plus délicates à bobiner car le pliage des bords pour le collage ou la fenêtre transparente pour la lecture d'une adresse procurent des variations d'épaisseurs. Les bobines ayant habituellement avec 300 mètres de longueur de bande un diamètre final de l'ordre de 1,40 mètre représentant environ 6 fois la largeur, sont très sensibles aux défauts d'alignement de la bande qui en répartissant de manière dissymétrique le serrage entraînent un cintrage des faces planes et un risque de décalage axiale des spires, voire d'effondrement de la bobine.This is particularly important for flat elements having a large width and a small height, for example for so-called commercial envelopes having a format of about 19 to 24 centimeters in width by 11 to 18 centimeters in height, and arranged transversely relative to the flow following the width, because the maintenance by the band acting on a low height does not provide a high stability of the product. These envelopes are more difficult to wind because the folding edges for the gluing or the transparent window for reading an address provide variations in thicknesses. The coils usually having a final diameter of about 1.40 meters, which is about 6 times the width, are very sensitive to the misalignment of the strip, which asymmetrically distributes the tightening. a bending of the flat faces and a risk of axial shift of the turns, or even collapse of the coil.

De plus, des déformations trop importantes de la bobine ou des enveloppes peuvent poser des problèmes de préhension des éléments plats par la machine les utilisant en aval et causer des rebuts.In addition, too large deformations of the coil or envelopes may cause gripping problems of the flat elements by the machine using them downstream and cause rejects.

Le réglage de la tension de la bande est aussi un facteur important de la qualité du bobinage en combinaison avec le positionnement de la bande. Des essais ont montrés que pour obtenir une bonne stabilité de la bobine et une déformation minimale des éléments plats, il est avantageux de commencer le bobinage avec une tension plus forte et de la réduire ensuite progressivement. En particulier, une décroissance linéaire de la tension en fonction de l'augmentation du diamètre de la bobine donne un bon résultat. Par exemple dans le cas du bobinage d'enveloppes citées ci-dessus, les meilleurs résultats sont obtenus avec des tensions de l'ordre de 300 Newton au départ et de 100 Newton à l'arrivée.The adjustment of the web tension is also an important factor in the quality of the winding in combination with the positioning of the web. Tests have shown that to obtain a good stability of the coil and minimal deformation of the flat elements, it is advantageous to start the winding with a higher voltage and then reduce it gradually. In particular, a linear decrease of the voltage as a function of the increase in the diameter of the coil gives a good result. For example, in the case of the winding of envelopes mentioned above, the best results are obtained with voltages of the order of 300 Newton at the start and 100 Newton at the arrival.

Pour obtenir ce réglage, il est avantageux d'utiliser un capteur 20 à ultrasons fixé sur le châssis 16 de la bobineuse qui mesure sans contact la variation de hauteur de l'axe de la bobine 8 et donc de son diamètre de manière à suivre la montée progressive de cet axe est à commander le couple de freinage en conséquence sur le motoréducteur 48.To obtain this adjustment, it is advantageous to use an ultrasonic sensor 20 fixed to the frame 16 of the winder which measures, without contact, the variation in height of the axis of the coil 8 and therefore of its diameter so as to follow the progressive rise of this axis is to control the braking torque accordingly on the geared motor 48.

Un autre avantage du dispositif de réglage de la tension de bande par un motoréducteur 48 commandé en couple moteur ou en couple frein, est que en cas d'incident lors du bobinage d'éléments plats, il est possible de débobiner partiellement la bobine 6 pour retirer les éléments défectueux. La bande 26 à libérer est alors enroulée à nouveau sur le moyeu 60 par le motoréducteur délivrant un couple moteur pour extraire les éléments plats défectueux. La courroie du convoyeur 12 n'ayant pas de motorisation propre suit de manière synchrone sans provoquer d'endommagement supplémentaire qui serait causé par un glissement sur les éléments plats, un débobinage de la partie défectueuse est réalisé proprement ce qui permet de relancer le bobinage là où les éléments sont bons et de réduire les pertes.Another advantage of the device for regulating the tension of the belt by a geared motor 48 controlled in motor torque or in brake torque, is that in the event of an incident during the winding of flat elements, it is possible to unwind the coil 6 remove the defective items. The strip 26 to be released is then rolled up again on the hub 60 by the geared motor delivering a driving torque to extract the flat elements. defective. The belt of the conveyor 12 having no clean motor follows synchronously without causing additional damage that would be caused by sliding on the flat elements, unwinding of the defective part is carried out properly which allows to restart the winding there where the elements are good and reduce the losses.
