Definitions
- the present invention relates to a modular device for removable folding in a folder-gluing machine of plate elements, in particular for cutting cardboard boxes.
- a pious gluer is a machine in which one takes the box cutouts, one by one from the top of a pile, and which is then transported through different folding and / or gluing sections using conveyors with belts, to receive them "folded flat” and glued in a terminal stacking station.
- the chronology of operations is usually: pre-crushing of the side tab, folding of the simple right and left front legs composed with reopening of the side tab, folding of the center-right front tab compound, gluing from above the front tabs compound, gluing from below the side tab and folding of the single tab front-left, folding along the second and fourth longitudinal folds with the right edge of the cut coming to close in the middle over the glued side tab, pressing and ejection at the outlet of which each folded cutout is stacked in a last receiving station.
- the usual chronology of operations is: folding of the simple front legs, then of the compound front legs, raising and folding of the compound rear legs, then of the simple rear legs, gluing from above of the front and rear compound tabs at four points on one side and two points on the other, folding and folding down according to the first longitudinal fold of the side tab over the adjacent glue points of the double-glued front and rear tabs, range along the second and fourth folds with the other lateral tab coming to be applied over the pair of adjacent glue dots, the two glue dots in the center being folded over the adjacent edges of the other compound tabs.
- the front legs are folded up using a relatively simple device comprising one or more hooks suspended in an elastic manner on a cross-member, the lower end of these hooks being found in the axis of passage of the legs of the cutout.
- the device for automatically raising the rear legs is a little more complex since it includes one or more underlying hooks which are rotated upward only when the rear leg passes, and this with a speed of movement greater than that of the cut.
- Folding along a longitudinal line is initiated by a twisted strip of polished metal, and is continued by a twisted ramp formed by one or more parallel bars of synthetic material having a low coefficient of friction with the cardboard.
- the ramp consists of a pair of associated drive belts, a twisted upper and a flat lower.
- the belts are usually driven by separate pulleys to better control their trajectory, these hens are usually mounted on the same drive shaft.
- Conveyors, hooks, ramps and twisted belts are permanently mounted in the machine on different crossbars, which allows their respective lateral positions to be adjusted according to the format of the cutout when changing series.
- we when we go from a production of "automatic bottom” boxes to a production of "six point” boxes, we must replace the last underlying sizing device for side tabs with a twisted metal ramp of turning the new side tab against the adjacent pair of glue dots. To do this, the glue wheel is removed from its drive shaft and the lower glue tank is removed.
- the object of the present invention is a device for folding the lateral cutting tab which does not induce any transverse position in the cutting, being based on a pair of drive belts: one comprising a twisted folding upper part and one comprising, in correspondence, a flat lower part, which, although more complex than a simple twisted metal ramp, can be installed very easily in place of a gluing device comprising a gluing wheel driven in rotation by a shaft.
- a gluing device comprising a gluing wheel driven in rotation by a shaft.
- the operation of this device must remain reliable, and its design must be as simple as possible to reduce the production costs accordingly.
- a range device because it is in the form of a removable module integrating attachment means to the frame of the machine, two sets of pulleys defining with one or two drive drums respectively the path of the belt with twisted part and of the belt with part in plane correspondence, and of the members for connecting the drum or drums to the drive shaft of the size wheel.
- Handling a complete module in one piece, possibly using lifting means, is almost as simple as that of a metal ramp.
- the correct positioning of this module leads without other exact positioning of the belts.
- the inspection and maintenance of such a module are greatly facilitated once this module is removed from the machine.
- the module comprises a vertical main plane support, such as a metal plate, the external face of which comprises means for hooking to the frame of the machine, and of which the internal face comprises the two sets of pulleys and the drive drum or drums of the two belts. If desired, this internal face further comprises a metal ramp for guiding and supporting the portion of the twisted beach belt.
- the internal face of the main support of the module only carries a large single drive drum side by side of the two belts, this main support having a passage of the drive shaft of the gluing wheel for direct connection to the drum hub.
- this hub has a conical surface coming into contact with the conical surface complementary to the end of the shaft.
- the main support has an upstream extension of extension of the path of the twisted part of the belt. This optimizes the dimensions of the main support.
- the module further comprises a vertical plane secondary support parallel to the main support and disposed opposite the path of the belt with a flat part of which it carries the guide pulleys.
- This secondary support forms the internal facade of the module thus protecting the drum and partially the pulleys and belts.
- This secondary support is particularly useful for carrying an elastic device for a tensioning pulley, this device comprising a movable part along a rectilinear opening formed in the support, and this at a level where the frame of the machine prevents keep it in the main support.
- the main support comprises at its upper edge gripping and / or lifting means such as a pair of handles.
- the attachment means to the frame belonging to the external face of the main support of the module can be in the form of a horizontal plate which is applied to the upper face of a part of the frame, this plate having one or more notches or openings through which the plate is fastened against the workpiece, the length of the notches and openings allowing the position of the module to be adjusted before the fastening means are tightened.
- the part of the frame is itself mounted on a cross member to adjust its lateral position.
- a folding module 100 is installed in place of a gluing device on a piece of frame 10 which is in the form of a frame.
- Two pipes 12 and 12 ′ of the upstream part of this piece of frame 10 are engaged by two cylindrical crosspieces of the machine: one for support and one thread for adjusting the lateral position.
- the downstream end of this frame 10 also has a semi-circular notch coming to engage in another cylindrical cross member in correspondence.
- the folding module 100 is structured around a main support plate 20 vertical plane whose external face 23 is provided with a horizontal hooking plate 24 coming to bear on the upper face of the frame part 10.
- This plate 24 comprises one or more notches or oblong openings 25 for the passage of fixing screws. These elongated openings thus allow an adjustment of the position of the module 100 relative to the piece of frame 10 before tightening.
- this main plate 20 has two rectangular openings 26 thus very simply forming two gripping handles allowing an operator to take out or replace this folding module very easily. If necessary, a chain can be passed between these two holes for attachment to a lifting means.
- the internal face 22 of the main support plate 20 carries substantially in the middle of its lower part a drive drum 30 mounted to rotate freely on a bearing.
- the conical central hub of this drum can be directly connected to the also conical end 32 of the transmission shaft 34 ( Figure 2) normally provided to drive a size wheel.
- This transmission shaft 34 comes from the external face, crosses the piece of frame 10 then a passage formed in correspondence in the main plate 20 to reach the hub of the drum 30.
- the main plate 20 comprises an upstream extension 21 making it possible to install, against the internal face 22, a long twisted metal ramp 51 for folding and turning the side cutting tab.
- this metal ramp 51 is covered by the part (a) of an upper belt 40 running in the same direction as the cutouts. At the end of this ramp, this belt 40 makes an upward turn (b) around a pulley 41 then performs an inverted spin (c) to an upper pulley 42 before descending down ( d) towards a third pulley 43 orienting this belt 40 around the drive drum 30 at a very large lashing angle (e).
- the belt starts again horizontally (g) towards a pulley 46 where it performs a round trip (f) around a tensioning pulley 45 to always start again horizontally (g ') to a pulley 47 located at the end of the upstream extension 21 returning it (h) at the start of its twisted trajectory (a).
- the axis of the pulley 45 passes through a longitudinal opening 44 at the rear of which the other end 45 ′ of this axis (FIG. 2) is pulled downstream by elastic means not shown.
- a secondary vertical plate 28, better visible in FIG. 1, is fixed in parallel vis-à-vis the main plate 20 by spacers not shown.
- the external face of this secondary plate 28, that is to say the face facing the main plate 20, carries a plurality of pulleys, also not shown, guiding a lower belt 50 having a planar part (a ') in screws -with respect to the downstream third of the twisted part (a) of the upper belt 40.
- this lower belt 50 is returned downwards (b ') to wrap around (e') of the drive drum 30 directly next to the lower belt 50.
- this lower belt passes (f ') around a pulley, the outer part of the axis 58 of which can be slid at inside a longitudinal groove 57 against the effort of elastic tensioning means not shown. Then this belt is returned by a half-turn upwards (h ') towards its flat trajectory (a').
- this folding module 100 is relatively easy insofar as it suffices to put it in place by lowering it slowly using the handles 26 for the place on the upper face of the frame piece 10. After adjusting the position, tighten the clamping screws passing through the notches 25, then connect the conical end 32 of the transmission shaft 34 to also conical hub of the drum 30. Once the machine is started, this drum simultaneously drives the two belts 40 and 50 which therefore travel at practically the same speed.
- a lateral cutting tab arriving at the level of the metal ramp 51 comes into contact with the upper belt 40 which drives it while performing its folding.
- this tab is turned more than 90 degrees, the lower part of the cutout is also grasped by the lower drive belt 50, and the end of the range is carried out reliably between the two belts progressing at the same speed, thus avoiding any cross position of the cut.

Abstract
Description
La présente invention est relative à un dispositif modulaire de pliage amovible dans une machine plieuse-colleuse d'éléments en plaque, notamment de découpes de boîtes en carton.The present invention relates to a modular device for removable folding in a folder-gluing machine of plate elements, in particular for cutting cardboard boxes.
Une pieuse colleuse est une machine dans laquelle on prend les découpes de boîtes, une à une du dessus d'une pile, et que l'on transporte ensuite au travers de différentes sections de pliage et/ou de collage à l'aide de convoyeurs à courroies, pour les recevoir "pliées à plat" et collées dans une station terminale d'empilage.A pious gluer is a machine in which one takes the box cutouts, one by one from the top of a pile, and which is then transported through different folding and / or gluing sections using conveyors with belts, to receive them "folded flat" and glued in a terminal stacking station.
Pour un type de boîte dit "à fond automatique", la chronologie des opérations est usuellement : un précassage de la patte latérale, pliage des pattes avant droite simple et gauche composées avec réouverture de la patte latérale, pliage de la patte avant centre-droite composée, encollage par le dessus des pattes avant composées, encollage par le dessous de la patte latérale et pliage de la patte simple avant-gauche, pliage le long du deuxième et quatrième plis longitudinaux avec le bord droit de la découpe venant se refermer au milieu par-dessus la patte latérale encollée, pressage et éjection à la sortie de laquelle chaque découpe pliée est empilée dans une dernière station de réception.For a type of box called "automatic bottom", the chronology of operations is usually: pre-crushing of the side tab, folding of the simple right and left front legs composed with reopening of the side tab, folding of the center-right front tab compound, gluing from above the front tabs compound, gluing from below the side tab and folding of the single tab front-left, folding along the second and fourth longitudinal folds with the right edge of the cut coming to close in the middle over the glued side tab, pressing and ejection at the outlet of which each folded cutout is stacked in a last receiving station.
Pour un autre type de boîte dit "à six points", la chronologie usuelle des opérations est : pliage des pattes avant simples, puis des pattes avant composées, relèvement et pliage des pattes arrière composées, puis des pattes arrière simples, encollage par le dessus des pattes composées avant et arrière en quatre points d'un côté et deux points de l'autre, pliage et rabattement selon le premier pli longitudinal de la patte latérale par-dessus les points de colle adjacents des pattes avant et arrière doublement encollées, plage le long du deuxième et quatrième plis avec l'autre patte latérale venant s'appliquer par-dessus la paire de points de colle adjacents, les deux points de colle du centre se rabattant par-dessus les bords adjacents des autres pattes composées.For another type of box called "six-point", the usual chronology of operations is: folding of the simple front legs, then of the compound front legs, raising and folding of the compound rear legs, then of the simple rear legs, gluing from above of the front and rear compound tabs at four points on one side and two points on the other, folding and folding down according to the first longitudinal fold of the side tab over the adjacent glue points of the double-glued front and rear tabs, range along the second and fourth folds with the other lateral tab coming to be applied over the pair of adjacent glue dots, the two glue dots in the center being folded over the adjacent edges of the other compound tabs.
Afin de transporter les découpes de boîtes sans glissement, tant latéral que longitudinal, au travers de la machine, on utilise en combinaison des transporteurs à courroies inférieurs et supérieurs ainsi que, dans certains cas, la combinaison d'un ou plusieurs transporteurs inférieurs à courroies avec des rampes supérieures de galets presseurs.In order to transport the box cutouts without sliding, both lateral and longitudinal, through the machine, use is made of conveyors with lower and upper belts as well as, in certain cases, the combination of one or more conveyors with lower belts with upper ramps of pinch rollers.
Le repliage des pattes avant s'effectue grâce à un dispositif relativement simple comportant un ou plusieurs crochets suspendus de manière élastique à une traverse, l'extrémité inférieure de ces crochets se retrouvant dans l'axe de passage des pattes de la découpe. Le dispositif de relèvement automatique des pattes arrière est un peu plus complexe car il comprend un ou plusieurs crochets sous-jacents mis en rotation vers le haut seulement au moment du passage de la patte arrière, et ce avec une vitesse de déplacement supérieure à celle de la découpe.The front legs are folded up using a relatively simple device comprising one or more hooks suspended in an elastic manner on a cross-member, the lower end of these hooks being found in the axis of passage of the legs of the cutout. The device for automatically raising the rear legs is a little more complex since it includes one or more underlying hooks which are rotated upward only when the rear leg passes, and this with a speed of movement greater than that of the cut.
Un pliage selon une ligne longitudinale est amorcé par une bande vrillée en métal poli, et est poursuivi par une rampe vrillée formée d'une ou plusieurs barres parallèles en matériau synthétique présentant un faible coefficient de friction avec le carton. Lorsque la partie à plier est lourde, la rampe est constituée d'une paire de courroies d'entraînement associées, une supérieure vrillée et une inférieure plane. Les courroies sont usuellement entraînées par des poulies distinctes pour mieux contrôler leur trajectoire, ces poules étant usuellement montées sur un même arbre d'entraînement.Folding along a longitudinal line is initiated by a twisted strip of polished metal, and is continued by a twisted ramp formed by one or more parallel bars of synthetic material having a low coefficient of friction with the cardboard. When the part to be folded is heavy, the ramp consists of a pair of associated drive belts, a twisted upper and a flat lower. The belts are usually driven by separate pulleys to better control their trajectory, these hens are usually mounted on the same drive shaft.
Les transporteurs, crochets, rampes et courroies vrillés sont montés à demeure dans la machine sur différentes traverses, ce qui permet de régler leurs positions latérales respectives selon le format de la découpe lors d'un changement de série. Notamment, lorsque l'on passe d'une production de boîtes "à fond automatique" à une production de boîtes "à six points", on doit substituer le dernier dispositif d'encollage sous-jacent de patte latérale par une rampe métallique vrillée de retournement de la nouvelle patte latérale contre la paire de points de colle adjacente. Pour ce, on démonte la roue d'encollage de son arbre d'entraînement et on retire le bac de colle inférieur.Conveyors, hooks, ramps and twisted belts are permanently mounted in the machine on different crossbars, which allows their respective lateral positions to be adjusted according to the format of the cutout when changing series. In particular, when we go from a production of "automatic bottom" boxes to a production of "six point" boxes, we must replace the last underlying sizing device for side tabs with a twisted metal ramp of turning the new side tab against the adjacent pair of glue dots. To do this, the glue wheel is removed from its drive shaft and the lower glue tank is removed.
Par ailleurs, lors de la production de boîtes "à six points", on constate que le rabattement de la patte latérale juste avant le pliage final induit très fréquemment un léger travers de la position de la découpe par rapport à son transporteur. Ce travers dû à la friction entre le carton et la rampe vrillée métallique fausse alors sensiblement le dernier pliage.Furthermore, during the production of "six-point" boxes, it can be seen that the folding of the side tab just before the final folding very frequently induces a slight cross-cut in the position of the cutout relative to its conveyor. This cross due to the friction between the cardboard and the metallic twisted ramp then substantially distorts the last folding.
Le but de la présente invention est un dispositif de pliage de patte latérale de découpe n'induisant aucun travers de position de la découpe en étant basé sur une paire de courroies d'entraînement : une comprenant une partie supérieure vrillée de pliage et une comprenant, en correspondance, une partie inférieure plane, qui, bien que plus complexe qu'une simple rampe métallique vrillée, puisse être installé très facilement à la place d'un dispositif d'encollage comprenant une roue encolleuse entraînée en rotation par un arbre. Toutefois, le fonctionnement de ce dispositif doit rester fiable, et sa conception doit être aussi simple que possible pour en réduire d'autant les coûts de réalisation.The object of the present invention is a device for folding the lateral cutting tab which does not induce any transverse position in the cutting, being based on a pair of drive belts: one comprising a twisted folding upper part and one comprising, in correspondence, a flat lower part, which, although more complex than a simple twisted metal ramp, can be installed very easily in place of a gluing device comprising a gluing wheel driven in rotation by a shaft. However, the operation of this device must remain reliable, and its design must be as simple as possible to reduce the production costs accordingly.
Ces buts sont atteints grâce à un dispositif de plage du fait qu'il se présente sous la forme d'un module amovible intégrant des moyens d'accrochage au bâti de la machine, deux séries de poulies définissant avec un ou deux tambours d'entraînement respectivement le trajet de la courroie à partie vrillée et de la courroie à partie en correspondance plane, et des organes de liaison du ou des tambours à l'arbre d'entraînement de la roue encolleuse.These goals are achieved thanks to a range device because it is in the form of a removable module integrating attachment means to the frame of the machine, two sets of pulleys defining with one or two drive drums respectively the path of the belt with twisted part and of the belt with part in plane correspondence, and of the members for connecting the drum or drums to the drive shaft of the size wheel.
La manipulation d'un module complet d'un seul tenant, éventuellement à l'aide de moyens de levage, s'avère pratiquement aussi simple que celle d'une rampe métallique. Notamment, le positionnement correct de ce module entraîne sans autre un positionnement exact des courroies. De plus, l'inspection et la maintenance d'un tel module sont grandement facilitées une fois ce module sorti de la machine.Handling a complete module in one piece, possibly using lifting means, is almost as simple as that of a metal ramp. In particular, the correct positioning of this module leads without other exact positioning of the belts. In addition, the inspection and maintenance of such a module are greatly facilitated once this module is removed from the machine.
Selon un mode de réalisation préféré, le module comprend un support principal plan vertical, tel qu'une plaque métallique, dont la face externe comprend des moyens d'accrochage au bâti de la machine, et dont la face interne comprend les deux séries de poulies et le ou les tambours d'entraînement des deux courroies. Si désiré, cette face interne comprend, en outre, une rampe métallique de guidage et d'appui de la partie de courroie vrillée de plage. Cette structure simplifiée facilite notablement sa réalisation et sa mise en place.According to a preferred embodiment, the module comprises a vertical main plane support, such as a metal plate, the external face of which comprises means for hooking to the frame of the machine, and of which the internal face comprises the two sets of pulleys and the drive drum or drums of the two belts. If desired, this internal face further comprises a metal ramp for guiding and supporting the portion of the twisted beach belt. This simplified structure significantly facilitates its realization and its implementation.
Selon un mode de réalisation préféré, la face interne du support principal du module ne porte qu'un large tambour unique d'entraînement côte-à-côte des deux courroies, ce support principal présentant un passage de l'arbre d'entraînement de la roue encolleuse pour liaison directe avec le moyeu du tambour. Notamment, ce moyeu présente une surface conique venant en contact avec la surface conique complémentaire de l'extrémité de l'arbre. Cet agencement simplifié limite les pertes de puissance mécanique entre l'arbre d'entraînement et les courroies. De plus, on assure que les vitesses des deux courroies sont pratiquement identiques.According to a preferred embodiment, the internal face of the main support of the module only carries a large single drive drum side by side of the two belts, this main support having a passage of the drive shaft of the gluing wheel for direct connection to the drum hub. In particular, this hub has a conical surface coming into contact with the conical surface complementary to the end of the shaft. This simplified arrangement limits the losses of mechanical power between the drive shaft and the belts. In addition, it is ensured that the speeds of the two belts are practically identical.
Avantageusement, le support principal présente un prolongement amont d'extension du trajet de la partie vrillée de la courroie. On optimise ainsi les dimensions du support principal.Advantageously, the main support has an upstream extension of extension of the path of the twisted part of the belt. This optimizes the dimensions of the main support.
Selon un mode de réalisation avantageux, le module comprend en outre un support secondaire plan vertical parallèle au support principal et disposé en vis-à-vis du trajet de la courroie à partie plane dont il porte les poulies de guidage. Ce support secondaire forme la façade interne du module protégeant ainsi le tambour et partiellement les poulies et courroies. Ce support secondaire est particulièrement utile pour porter un dispositif élastique pour une poulie de mise en tension, ce dispositif comprenant une pièce mobile le long d'une lumière rectiligne pratiquée dans le support, et ce à un niveau où le bâti de la machine empêche de le ménager dans le support principal.According to an advantageous embodiment, the module further comprises a vertical plane secondary support parallel to the main support and disposed opposite the path of the belt with a flat part of which it carries the guide pulleys. This secondary support forms the internal facade of the module thus protecting the drum and partially the pulleys and belts. This secondary support is particularly useful for carrying an elastic device for a tensioning pulley, this device comprising a movable part along a rectilinear opening formed in the support, and this at a level where the frame of the machine prevents keep it in the main support.
Avantageusement, le support principal comprend en son bord supérieur des moyens de préhension et/ou de levage tels qu'une paire de poignées.Advantageously, the main support comprises at its upper edge gripping and / or lifting means such as a pair of handles.
Les moyens d'accrochage au bâti appartenant à la face externe du support principal du module peuvent se présenter sous la forme d'une plaque horizontale venant s'appliquer sur la face supérieure d'une pièce du bâti, cette plaque présentant une ou plusieurs encoches ou lumières traversées par des moyens de fixation de la plaque contre la pièce, la longueur des encoches et lumières autorisant un ajustement de la position du module avant serrage des moyens de fixation. De préférence, la pièce du bâti est elle-même montée sur traverse pour réglage de sa position latérale.The attachment means to the frame belonging to the external face of the main support of the module can be in the form of a horizontal plate which is applied to the upper face of a part of the frame, this plate having one or more notches or openings through which the plate is fastened against the workpiece, the length of the notches and openings allowing the position of the module to be adjusted before the fastening means are tightened. Preferably, the part of the frame is itself mounted on a cross member to adjust its lateral position.

Comme illustré sur les figures, un module de pliage 100 est installé en lieu et place d'un dispositif d'encollage sur une pièce de bâti 10 se présentant sous la forme d'un cadre. Deux tubulures 12 et 12' de la partie amont de cette pièce de bâti 10 sont engagées par deux traverses cylindriques de la machine : une de support et une filetée de réglage de la position latérale. L'extrémité aval de ce cadre 10 présente également une encoche semi-circulaire venant s'engager dans une autre traverse cylindrique en correspondance.As illustrated in the figures, a
Comme mieux visible sur la figure 2, le module de pliage 100 est charpenté autour d'une plaque de support principale 20 plane verticale dont la face externe 23 est garnie d'une plaque horizontale d'accrochage 24 venant prendre appui sur la face supérieure de la pièce de bâti 10. Cette plaque 24 comprend une ou plusieurs encoches ou ouvertures oblongues 25 pour le passage de vis de fixation. Ces ouvertures allongées permettent ainsi un ajustement de la position du module 100 par rapport à la pièce de bâti 10 avant serrage.As best seen in FIG. 2, the
Le bord supérieur de cette plaque principale 20 présente deux ouvertures rectangulaires 26 formant ainsi très simplement deux poignées de préhension permettant à un opérateur de sortir ou remettre en place ce module de pliage très facilement. Si nécessaire, une chaîne peut être passée entre ces deux orifices pour accrochage à un moyen de levage.The upper edge of this
Tel qu'illustré sur la figure 1, la face interne 22 de la plaque de support principale 20 porte sensiblement au milieu de sa partie inférieure un tambour d'entraînement 30 monté libre en rotation sur un palier. Le moyeu central conique de ce tambour peut être directement relié à l'extrémité 32 également conique de l'arbre de transmission 34 (figure 2) normalement prévu pour entraîner une roue encolleuse. Cet arbre de transmission 34 vient de la face externe, traverse la pièce de bâti 10 puis un passage ménagé en correspondance dans la plaque principale 20 pour atteindre le moyeu du tambour 30.As illustrated in FIG. 1, the
Comme bien visible sur les deux figures, la plaque principale 20 comprend un prolongement amont 21 permettant d'installer, contre la face interne 22, une longue rampe métallique vrillée 51 de pliage et retournement de patte latérale de découpe.As clearly visible in the two figures, the
Plus particulièrement selon l'invention, cette rampe métallique 51 est recouverte par la partie (a) d'une courroie supérieure 40 défilant dans le même sens que les découpes. A l'extrémité de cette rampe, cette courroie 40 effectue un demi-tour vers le haut (b) autour d'une poulie 41 puis effectue une vrille inversée (c) jusqu'à une poulie supérieure 42 avant de redescendre vers le bas (d) vers une troisième poulie 43 orientant cette courroie 40 autour du tambour d'entraînement 30 selon un angle d'embarrage (e) très important. A la sortie de ce tambour, la courroie repart à l'horizontale (g) vers une poulie 46 où elle effectue un aller-retour (f) autour d'une poulie de mise sous tension 45 pour repartir toujours à l'horizontale (g') vers une poulie 47 située à l'extrémité du prolongement amont 21 la renvoyant (h) au départ de sa trajectoire vrillée (a). Comme on peut l'observer sur la figure 1, l'axe de la poulie 45 passe au travers d'une ouverture longitudinale 44 à l'arrière de laquelle l'autre extrémité 45' de cet axe (figure 2) est tirée vers l'aval par des moyens élastiques non illustrés.More particularly according to the invention, this
Une plaque verticale secondaire 28, mieux visible sur la figure 1, est fixée parallèlement en vis-à-vis de la plaque principale 20 par des entretoises non représentées. La face externe de cette plaque secondaire 28, c'est-à-dire la face orientée vers la plaque principale 20, porte une pluralité de poulies, également non représentées, guidant une courroie inférieure 50 présentant une partie plane (a') en vis-à-vis du tiers aval de la partie vrillée (a) de la courroie supérieure 40. A la hauteur de la poule 41, cette courroie inférieure 50 est renvoyée vers le bas (b') pour s'enrouler (e') autour du tambour d'entraînement 30 directement à côté de la courroie inférieure 50. En sortie de ce tambour 30, cette courroie inférieure passe (f') autour d'une poulie dont on peut observer la partie extérieure de l'axe 58 coulissant à l'intérieur d'une rainure longitudinale 57 contre l'effort de moyens élastiques de mise en tension non illustrés. Puis cette courroie est renvoyée par un demi-tour vers le haut (h') vers sa trajectoire plane (a').A secondary
Comme on peut le constater à la lecture de ce qui précède, la mise en oeuvre de ce module de pliage 100 est relativement aisée dans la mesure où il suffit de le mettre en place en le descendant lentement à l'aide des poignées 26 pour le poser sur la face supérieure de la pièce de bâti 10. Après un réglage de la position, on serre les vis de serrage traversant les encoches 25, puis on réalise l'accouplement de l'extrémité conique 32 de l'arbre de transmission 34 au moyeu également conique du tambour 30. Une fois la machine mise en route, ce tambour entraîne simultanément les deux courroies 40 et 50 qui défilent donc pratiquement à la même vitesse.As can be seen from the foregoing, the implementation of this
Ainsi, une patte latérale de découpe arrivant au niveau de la rampe métallique 51 entre en contact avec la courroie supérieure 40 qui l'entraîne tout en effectuant son pliage. Lorsque cette patte est retournée à plus de 90 degrés, la partie inférieure de la découpe est également appréhendée par la courroie d'entraînement inférieure 50, et la fin du plage s'effectue de manière fiable entre les deux courroies progressant à la même vitesse, évitant ainsi tout travers de position de la découpe.Thus, a lateral cutting tab arriving at the level of the
De nombreuses améliorations peuvent être apportées à ce module de pliage dans le cadre des revendications.Many improvements can be made to this folding module within the scope of the claims.
