Description

L'invention se rapporte à un dispositif de dévidage de rouleaux de feuilles ou rubans et en particulier de rouleaux de papier utilisés dans l'industrie de l'imprimerie et des arts graphiques.The invention relates to a device for unwinding rolls of sheets or ribbons and in particular paper rolls used in the printing and graphic arts industry.

L'invention se rapporte plus particulièrement à un dispositif du type dit dérouleur comportant un magasin accumulateur permettant de raccorder les extrémités de deux rouleaux successifs sans nécessiter un arrêt prolongé et sans qu'il soit nécessaire de repasser une extrémité d'une bande dans un chemin de poulie qui soit long et difficile d'accès.The invention relates more particularly to a device of the so-called unwinder type comprising an accumulator magazine making it possible to connect the ends of two successive rollers without requiring a prolonged stop and without it being necessary to iron one end of a strip in a path pulley that is long and difficult to access.

L'invention permet également de réaliser une coupe et un collage simultanés, bout à bout, des extrémités de deux bandes déroulées de deux rouleaux successifs.The invention also makes it possible to carry out a simultaneous cutting and bonding, end to end, of the ends of two strips unwound from two successive rolls.

L'invention vise à perfectionner les appareils existants en faisant en sorte qu'il ne soit pas nécessaire d'introduire manuellement un mandrin à l'intérieur des rouleaux et elle permet d'exécuter toutes les opérations au moyen d'organes mécaniques. Par ailleurs, lorsque la bande ou la feuille est déroulée d'un rouleau, la broche, qui supporte le rouleau, est elle-même supportée à ses deux extrémités, ce qui assure une grande stabilité au déroulement.The invention aims to improve existing devices by ensuring that it is not necessary to manually insert a mandrel inside the rollers and it allows all operations to be carried out by means of mechanical members. Furthermore, when the strip or the sheet is unwound from a roll, the spindle, which supports the roll, is itself supported at its two ends, which ensures great stability during unwinding.

Conformément à l'invention, le dispositif de mise en place et de raccordement de rouleaux de feuilles de papier et analogues comporte au moins un chariot monté pour être déplaçable le long de moyens de guidage, ledit chariot comportant sur un côté un montant muni de glissières pour le guidage d'un second chariot déplaçable axialement le long du montant, ledit second chariot étant muni d'une broche engagée dans un rouleau soulevé par déplacement de la broche faisant saillie dudit rouleau pour être engagé par déplacement du chariot dans un organe d'accouplement tournant monté à poste fixe de façon que ladite broche soit supportée à ses deux extrémités lorsque la feuille ou bande dévidée d'un rouleau est passée dans un chemin de poulies.According to the invention, the device for placing and connecting rolls of paper sheets and the like comprises at least one carriage mounted to be movable along guide means, said carriage comprising on one side an upright provided with slides for guiding a second carriage movable axially along the upright, said second carriage being provided with a spindle engaged in a roller lifted by displacement of the spindle projecting from said roller to be engaged by displacement of the carriage in a rotary coupling member mounted at a fixed station so that said spindle is supported at its two ends when the sheet or strip unwound from a roller went through a pulley path.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, au dessin annexé.An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.

La fig. 1 est une élévation schématique du dispositif de mise en place et de raccordement de rouleaux de feuilles selon l'invention.Fig. 1 is a schematic elevation of the device for placing and connecting rolls of sheets according to the invention.

La fig. 2 est une élévation tournée de 90° du dispositif de la fig. 1, l'un des éléments du dispositif étant illustré dans une position particulière.Fig. 2 is a 90 ° turned elevation of the device of FIG. 1, one of the elements of the device being illustrated in a particular position.

Le dispositif illustré au dessin comporte un bâti 1 à l'intérieur duquel est disposé un magasin accumulateur 2 pour une bande 3 constituée par exemple par une feuille de papier enroulée autour de poulies 4, 5 faisant partie d'un chemin de poulies et disposées à la manière de moufles maintenues sous tension constante par un vérin 6 ou un système à contrepoids ou analogue. Les poulies 5 sont mobiles le long d'un guide 7 de manière que la bande ou feuille passant sur les poulies constitue une réserve.The device illustrated in the drawing comprises a frame 1 inside which is disposed an accumulator magazine 2 for a strip 3 constituted for example by a sheet of paper wound around pulleys 4, 5 forming part of a path of pulleys and arranged at the manner of mittens kept under constant tension by a jack 6 or a counterweight system or the like. The pulleys 5 are movable along a guide 7 so that the strip or sheet passing over the pulleys constitutes a reserve.

Le bâti 1 est relié à un bâti secondaire 8 par un portique 9 ou un autre moyen assurant une bonne rigidité des bâtis l'un par rapport à l'autre.The frame 1 is connected to a secondary frame 8 by a gantry 9 or another means ensuring good rigidity of the frames relative to each other.

L'espace compris entre le bâti 1 et le bâti secondaire 8 comporte des moyens de guidage 10, par exemple des rails de préférence encastrés dans le sol pour un chariot 11 comportant avantageusement deux longerons 12 réunis par une traverse 13 pour constituer un châssis en U porté par des roues 14.The space between the frame 1 and the secondary frame 8 comprises guide means 10, for example rails preferably embedded in the ground for a carriage 11 advantageously comprising two side members 12 joined by a cross member 13 to form a U-shaped frame carried by wheels 14.

Le châssis ci-dessus supporte, par sa traverse 13, un montant 15 comportant des glissières 16 pour le guidage d'un second chariot 17 déplaçable le long des glissières 16 au moyen d'un organe de manoeuvre 18 par exemple un pistolet pneumatique d'actionnement d'un vérin mécanique 19 ou analogue.The above chassis supports, by its cross 13, an upright 15 having slides 16 for guiding a second carriage 17 movable along the slides 16 by means of an operating member 18 for example a pneumatic gun actuation of a mechanical jack 19 or the like.

Le chariot supporte une broche 20 (fig. 2) sur laquelle est engagé un rouleau 21 par exemple un rouleau de papier.The carriage supports a pin 20 (fig. 2) on which is engaged a roller 21, for example a paper roll.

La broche 20 est munie d'un moyen de blocage 22, par exemple un mandrin ou autre élément pneumatique ou mécanique, pour verrouiller ensemble la broche et le rouleau de papier. Un volant 18a sert à l'expansion du mandrin et donc au blocage du rouleau sur la broche.The spindle 20 is provided with a locking means 22, for example a mandrel or other pneumatic or mechanical element, for locking the spindle and the paper roll together. A flywheel 18 a is used for expanding the mandrel and therefore for blocking the roller on the spindle.

Comme l'illustre la fig. 2, l'extrémité libre de la broche 20, qui est en porte-à-faux, fait saillie du rouleau 21 et présente, sur sa partie saillante, un cône de centrage 23 prolongé par une noix d'entraînement 24, par exemple de section carrée, qui est destinée à être introduite dans un organe d'accouplement 25 d'un arbre moteur 26 faisant saillie d'un ensemble moteur 27 monté fixement et de préférence relié rigidement au bâti 1 et au bâti secondaire 8.As illustrated in fig. 2, the free end of the spindle 20, which is cantilevered, projects from the roller 21 and has, on its projecting part, a centering cone 23 extended by a drive nut 24, for example of square section, which is intended to be introduced into a coupling member 25 of a motor shaft 26 projecting from a motor assembly 27 fixedly mounted and preferably rigidly connected to the frame 1 and to the secondary frame 8.

Le dispositif comporte deux chariots identiques 11 et 11a pour deux rouleaux 21, 21a. La fig. 1 montre qu'un ensemble moteur 27a, identique à l'ensemble moteur 27, est disposé au-delà du bâti secondaire 8 sur des rails ou autres moyens de guidage 10a, également encastrés dans le sol.The device comprises two identical carriages 11 and 11 has two rollers 21, 21a. Fig. 1 shows that an engine assembly 27 a , identical to the engine assembly 27, is disposed beyond the secondary frame 8 on rails or other guide means 10 a , also embedded in the ground.

La feuille 3 dévidée du rouleau 21 passe par un chemin de poulies comportant un cabestan 28 et des poulies de guidage de retenue 29 et de renvoi 30 menant aux poulies du magasin accumulateur 2.The sheet 3 unwound from the roller 21 passes through a pulley path comprising a capstan 28 and retaining guide pulleys 29 and return pulleys 30 leading to the pulleys of the accumulator magazine 2.

De façon analogue, la bande 3a dévidée du rouleau 21a passe sur un cabestan 28a et des poulies de retenue 31 maintenant cette bande contre la bande 3 sur une partie de son trajet.Similarly, the strip 3 has unwound from the roller 21 a passes over a capstan 28 a and retaining pulleys 31 holding this strip against the strip 3 over part of its path.

Des organes de collage 32 et de coupe 33 connus en eux-mêmes sont disposés sur la partie des bandes dévidées accolées l'une à l'autre pour permettre leur jonction à la fin du dévidage des rouleaux successifs.Gluing members 32 and cutting members 33 known in themselves are arranged on the part of the unwound strips attached to one another to allow their joining at the end of the unwinding of the successive rollers.

Le dispositif fonctionne de la façon suivante :The device works as follows:

Un premier rouleau, par exemple le rouleau 21, est amené en le faisant rouler sur le sol ou en le déplaçant par un autre moyen en regard de l'un des chariots, par exemple le chariot 11, alors que celui-ci se trouve écarté des bâtis 1 et 8. Le chariot 11 est alors avancé après réglage de la hauteur de la broche 20 au moyen de l'organe de manoeuvre 18 pour l'amener en coïncidence avec le mandrin du rouleau. Le roulage au sol du rouleau 21 est facilité par l'encastrement des rails.A first roller, for example the roller 21, is brought by rolling it on the ground or by moving it by another means opposite one of the carriages, for example the carriage 11, while the latter is spaced frames 1 and 8. The carriage 11 is then advanced after adjusting the height of the spindle 20 by means of the operating member 18 to bring it into coincidence with the mandrel of the roller. The rolling on the ground of the roller 21 is facilitated by the embedding of the rails.

L'organe de manoeuvre 18 est de nouveau actionné pour déplacer la broche 20 dans le sens pour lequel elle soulève le rouleau 21 qui est alors bloqué par le moyen de blocage 22.The actuator 18 is again actuated to move the spindle 20 in the direction for which it lifts the roller 21 which is then blocked by the locking means 22.

Le chariot 11 est ensuite de nouveau déplacé pour l'amener entre les bâtis 1 et 8 en faisant en sorte que sa noix 24 entre dans l'organe d'accouplement 25. Le cône de centrage 23 assure, par ailleurs. un maintien précis de l'extrémité libre de la broche 20 qui est ainsi suspendue, d'une part, au chariot 17 et, d'autre part, à l'organe d'accouplement 25, comportant un palier approprié mais non représenté. Les deux extrémités de la broche sont ainsi supportées à rotation.The carriage 11 is then again moved to bring it between the frames 1 and 8 by ensuring that its nut 24 enters the coupling member 25. The centering cone 23 also provides. precise maintenance of the free end of the spindle 20 which is thus suspended, on the one hand, from the carriage 17 and, on the other hand, from the coupling member 25, comprising an appropriate bearing but not shown. The two ends of the spindle are thus rotatably supported.

La feuille ou bande externe du rouleau 21 est ensuite amenée à passer sur le cabestan 28 et les poulies 29, 30 puis les poulies 4, 5 du magasin accumulateur 2 pour être conduite comme illustré en 31 à un dispositif d'utilisation.The sheet or external strip of the roller 21 is then brought to pass over the capstan 28 and the pulleys 29, 30 then the pulleys 4, 5 of the accumulator magazine 2 in order to be carried as shown in 3 1 to a device for use.

Le second chariot 11a est chargé de manière analogue au moyen du rouleau 21a et il est déplacé pour que sa broche 20 soit reliée à l'organe d'accouplement correspondant 25 de l'ensemble moteur 27a.The second carriage 11 a is loaded in a similar manner by means of the roller 21 a and it is moved so that its pin 20 is connected to the corresponding coupling member 25 of the motor assembly 27 a .

La bande 3a provenant du rouleau 21a est passée sur le cabestan 28a et les poulies de guidage 31 correspondant aux poulies 29 suivies par la bande 3. L'opération de mise en place du rouleau 21a et donc de la bande 3a peut être effectuée pendant l'utilisation de la bande 3 dévidée du rouleau 21.The strip 3 has from the roller 21a is placed on the capstan 28a and the guide pulleys 31 corresponding to the pulleys 29 followed by the strip 3. The setting operation of the roller 21a and thus of the strip 3 has can be performed while using the strip 3 unwound from the roll 21.

Lorsque le rouleau 21 arrive à son terme, la bande 3 est ralentie par le moteur d'entraînement du moyeu 25 et de la broche 21, jusqu'à l'arrêt complet.When the roller 21 comes to an end, the strip 3 is slowed down by the drive motor of the hub 25 and of the spindle 21, until the complete stop.

Le dispositif de déroulement 30 est alors bloqué, au moyen d'un frein électromagnétique non représenté, par exemple de façon à maintenir l'arrêt complet.The unwinding device 30 is then blocked, by means of an electromagnetic brake not shown, for example so as to maintain the complete stop.

Pendant ce temps, la bande 31 continue à être appelée par la machine, qui est alors alimentée par la réserve du magasin accumulateur 2.During this time, the strip 3 1 continues to be called by the machine, which is then supplied by the reserve of the accumulator magazine 2.

Les deux bandes du rouleau tint 21 et du nouveau rouleau 21a sont alors coupées simultanément par l'organe de coupe 33, puis collées à l'aide de deux bandes adhésives, préparées sur les mâchoires de l'organe de collage 32.The two bands of the roller tint 21 and of the new roller 21 a are then cut simultaneously by the cutting member 33, then glued using two adhesive strips, prepared on the jaws of the gluing member 32.

Le dispositif 30 est alors libéré, puis le nouveau rouleau accéléré jusqu'au remplissage du magasin accumulateur 2.The device 30 is then released, then the new roller accelerated until the filling of the accumulator magazine 2.

Un nouveau rouleau 21 peut être mis en place comme expliqué dans ce qui précède.A new roller 21 can be put in place as explained in the foregoing.

Ainsi que cela ressort de la description qui précède, le magasin accumulateur 2 permet un usage sans interruption de la bande qu'il contient par déplacement des poulies 5 au moment de l'immobilisation des fins de bande provenant de l'un ou l'autre des rouleaux 21 ou 21a.As is apparent from the above description, the accumulator magazine 2 allows uninterrupted use of the strip it contains by moving the pulleys 5 when the end of the strip coming from one or the other is immobilized. rollers 21 or 21 a .

L'invention n'est pas limitée à l'exemple de réalisation, représenté et décrit en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre. En particulier, dans certaines applications, l'organe d'accouplement 25 peut être porté par un palier libre lorsque le dévidage des rouleaux est assuré par des cabestans ou autres moyens analogues. De même, lorsqu'il n'est pas nécessaire d'assurer un fonctionnement en continu, le dispositif peut comporter un seul chariot 11 pour un seul rouleau 21. Dans ce cas, un frein est prévu pour immobiliser temporairement la fin de bande, par exemple au niveau du cabestan 28.The invention is not limited to the embodiment, shown and described in detail, because various modifications can be made without departing from its scope. In particular, in certain applications, the coupling member 25 can be carried by a free bearing when the unwinding of the rollers is provided by capstans or other similar means. Likewise, when it is not necessary to ensure continuous operation, the device can comprise a single carriage 11 for a single roller 21. In this case, a brake is provided for temporarily immobilizing the end of the strip, by example at capstan 28.
