Definitions
- the present invention relates to a folding device of tabs for cut-off boxes boxes transverse to the direction of displacement of the blanks, for folder-gluer, comprising a member rotatable about an axis transverse to said direction of displacement, provided with at least one folding member.
- devices comprising a folding member mounted on a transverse rotating shaft and having a single hook-shaped folder.
- a similar device is also known comprising two hook-shaped pliers arranged symmetrically with respect to the axis of the transverse rotary shaft. This or these benders are mounted on a central hub that can be moved laterally along the transverse rotary shaft. The box cut moves over the rotatable bending member and the benders will bend the tab from the back while the box cut is moving. Therefore, the movement of the folder should be at a higher speed than that of the box cut.
- the end of the folding hook When folding the tab, the end of the folding hook must come into contact with the tab to be folded in a favorable zone which is approximately two thirds of the length of the tab from the transverse delivery line around which the leg must be folded.
- the transverse shaft of the rotary folding member is located at a fixed distance from the passage plane of the cuts and it is necessary either to change the length of the hooks or to place on the central hub supporting the folding hooks, shims, to work in the favorable area of the tab to bend.
- Such a device is described in US Patent 3,330,185. It has the main drawback the time required for adjustment and the difficulty of positioning the folding hook in the area favorable to folding.
- FR 2 '597' 027 proposes to overcome the drawbacks of the aforementioned solution by a device in which a plurality of motors are controlled by a pulse converter transforming the values of motion curves calculated by a function generator receiving data. a cut-off detector and parameters relating to the characteristic dimensions of these blanks. These different motors each act according to different degrees of freedom of the device and make it possible to optimize the displacement of the folding hooks.
- the object of the present invention is to overcome, at least in part, the disadvantages of the aforementioned solutions.
- the subject of the present invention is a device for folding box cut tabs having upsetting lines arranged transversely to the direction of movement of the blanks, for folder-gluer, according to claim 1.
- This device is simple. It can be mounted on any suitable medium of the folder-gluer, which can fit inside any space left free in the machine. Indeed, the device being completely autonomous, the support on which it is mounted has no other function since the device is driven by a motor synchronized with the drive mechanism of the folder-gluer and not directly by this drive mechanism.
- the device according to the invention comprises a housing 1 of elongate shape having two large parallel faces connected by relatively narrow side faces.
- One of the large parallel faces of this housing 1 carries a drive motor 2 whose shaft extends inside this housing.
- a toothed pulley 3, located in the housing 1, is keyed at the end of this tree.
- This toothed pulley 3 is engaged with a toothed belt 4 forming an endless loop engaged with a second toothed pulley (hidden by the walls of the housing 1), integral with a shaft 5 rotatably mounted in the walls of the housing 1 and one end protrudes from this housing 1.
- the end of the shaft 5 carries two folding arms 6 in the form of hooks, arranged symmetrically with respect to a plane containing the longitudinal axis of the shaft 5.
- These folding arms 6 are integral with the shaft 5, so that they are driven by him when the motor 2 drives the belt 4 in engagement with the toothed pulley 3. It is obvious that by adapting the speed of rotation of the engine 2 could be imagined n ' use only one hook-shaped folding arm.
- the two elongated lateral faces of the casing 1 each have an eagle tail slide 7, 8.
- These slides 7, 8 serve selectively for mounting the casing on the folder-gluer, which is shown in FIGS. two side portions of the frame B and the drive mechanism 9 of the box blanks, and a support cross member 10 of this device which extends between the two side portions of the frame B.
- One of the slides 7, 8 of the housing 1 is intended to receive connecting means to the support beam 10 which essentially comprise a connecting plate 11 associated on the one hand with screw slides 12 which engage in one of the slides 7, 8 and allow to tighten the connecting plate 11 in the desired position along the slide 7 or 8.
- This connecting plate 11 still carries, on the other hand, two clamping arms 13 for its attachment along the cross support 10.
- suppor t 10 has a polygonal section, square in the example shown, to allow to define the orientation of the connecting plate 11 relative to the longitudinal axis of the support cross member 10.
- the screw sliders 12 are aligned along an axis perpendicular to the axis on which the clamping arms are aligned, so as to form fixing means adjustable in two orthogonal directions.
- the housing 1 thus has a possibility of adjustment in two degrees of freedom, one transverse, with respect to the support cross member 10 in engagement with the clamping arms 13, the other vertical along the one of the slides 7, 8 engaged with the screw slides 12.
- the device comprises a laser cell 14 intended to detect the transition to a specific reference location of a trailing edge of each box cutout.
- This laser cell 14 is connected to a control box 15 of the drive motor 2 (FIGS. 2 and 3).
- the synchronization means of the device also comprise an encoder 16 connected on the one hand by a desmodromic link (that is to say by a link such that the speed of rotation of the encoder 16 causes a determined speed for the rotation of the driving mechanism 9) to the drive mechanism 9 of the box blanks and secondly, by an electrical connection, to the control unit 15 of the drive motor 2.
- This information makes it possible to control the motor 2 in a synchronous manner with the forward speed of the box blanks and their frequency of passage to the detection location which is a function of the length of the blanks of boxes in the direction of their scrolling F in the folder-gluer.
- the control box 15 must still receive information on the characteristics of the cuts to provide programming of the drive motor. This information is entered by the operator of the machine. However, since the programming mode does not form part of the present invention, it is not necessary to describe it here.
- the folding device described is autonomous in its operation, which allows it to be disposed practically anywhere there is free space on a folder-gluer.
- its connection mode allows to adjust its position according to the length of the legs of the cutouts of boxes to bend. It is even possible to place two folding devices so that they fold two tabs whose crease lines are aligned transversely, but whose lengths are different, simply by varying the distance h between the axis of the tree. 5 of the bending arms 6 and the plane P of the displacement path of the box blanks (FIGS. 4 and 5), by sliding the housing 1 with respect to the connecting plate 11 and by tightening the screw slides 12 when the desired distance h is obtained.
- a table indicating the value of h according to the length of the tabs of the blanks can be established for the operator.
- FIGS. 4 and 5 show the relative positions of the axis of the shaft 5 of the folding arms 6 for lengths of box cutout tabs of 20 to 25 mm, respectively 71 to 100 mm, with folding arms 6 of 100 mm radius.
- Another possibility offered by the device that is the subject of the present invention consists in using the folding arms 6 to hold the transverse creasing line. around which the leg is folded on the inside of the fold. Indeed, if, during folding, the crease line, under the effect of the force exerted on the folding tab of the outer side to the fold, takes a convex shape of the inner side of the fold, the folding of the leg is no longer possible. This risk is eliminated if the crease line is held at the beginning of the folding operation. This is made possible by the device object of the present invention since nothing prevents to place this device above the plane P of the trajectory of the blanks boxes.

Abstract
Description
La présente invention se rapporte à un dispositif de pliage de pattes de découpes de boîtes à lignes de refoulage transversales à la direction de déplacement des découpes, pour plieuse-colleuse, comprenant un organe rotatif autour d'un axe transversal à ladite direction de déplacement, muni d'au moins un organe de pliage.The present invention relates to a folding device of tabs for cut-off boxes boxes transverse to the direction of displacement of the blanks, for folder-gluer, comprising a member rotatable about an axis transverse to said direction of displacement, provided with at least one folding member.
On connaît, dans le domaine du pliage des pattes de boîtes pliantes, des dispositifs comprenant un organe de pliage monté sur un arbre rotatif transversal et comportant un seul plieur en forme de crochet. On connaît également un dispositif semblable comportant deux plieurs en forme de crochets disposés symétriquement par rapport à l'axe de l'arbre rotatif transversal. Ce ou ces plieurs sont montés sur un moyeu central que l'on peut déplacer latéralement le long de l'arbre rotatif transversal. La découpe de boîte se déplace au-dessus de l'organe de pliage rotatif et les plieurs vont plier la patte depuis l'arrière pendant le déplacement de la découpe de boîte. Par conséquent, le déplacement du plieur devra s'effectuer à une vitesse supérieure à celle de la découpe de boîte.In the field of folding folding box tabs, devices are known comprising a folding member mounted on a transverse rotating shaft and having a single hook-shaped folder. A similar device is also known comprising two hook-shaped pliers arranged symmetrically with respect to the axis of the transverse rotary shaft. This or these benders are mounted on a central hub that can be moved laterally along the transverse rotary shaft. The box cut moves over the rotatable bending member and the benders will bend the tab from the back while the box cut is moving. Therefore, the movement of the folder should be at a higher speed than that of the box cut.
Lors du pliage de la patte, l'extrémité du crochet de pliage doit entrer en contact avec la patte à plier dans une zone favorable qui se situe environ à deux tiers de la longueur de la patte depuis la ligne de refoulement transversal autour de laquelle la patte doit être pliée. L'arbre transversal de l'organe de pliage rotatif est situé à une distance fixe par rapport au plan de passage des découpes et on est obligé soit de modifier la longueur des crochets, soit de placer sur le moyeu central supportant les crochets de pliage, des cales d'épaisseur, pour travailler dans la zone favorable de la patte à plier. Un tel dispositif est décrit dans le brevet US 3'330'185. Il a pour principal inconvénient la durée nécessaire au réglage et la difficulté de positionner le crochet de pliage dans la zone favorable au pliage.When folding the tab, the end of the folding hook must come into contact with the tab to be folded in a favorable zone which is approximately two thirds of the length of the tab from the transverse delivery line around which the leg must be folded. The transverse shaft of the rotary folding member is located at a fixed distance from the passage plane of the cuts and it is necessary either to change the length of the hooks or to place on the central hub supporting the folding hooks, shims, to work in the favorable area of the tab to bend. Such a device is described in US Patent 3,330,185. It has the main drawback the time required for adjustment and the difficulty of positioning the folding hook in the area favorable to folding.
On a proposé dans le FR 2' 597' 027 de remédier aux inconvénients de la solution susmentionnée par un dispositif dans lequel plusieurs moteurs sont commandés par un convertisseur d'impulsions transformant les valeurs de courbes de mouvement calculées par un générateur de fonction recevant des données d'un détecteur de passage des découpes et les paramètres relatifs aux dimensions caractéristiques de ces découpes. Ces différents moteurs agissent chacun selon différents degrés de liberté du dispositif et permettent d'optimiser le déplacement des crochets de pliage.FR 2 '597' 027 proposes to overcome the drawbacks of the aforementioned solution by a device in which a plurality of motors are controlled by a pulse converter transforming the values of motion curves calculated by a function generator receiving data. a cut-off detector and parameters relating to the characteristic dimensions of these blanks. These different motors each act according to different degrees of freedom of the device and make it possible to optimize the displacement of the folding hooks.
Une telle solution est cependant relativement complexe et donc coûteuse. Cette complexité vient en grande partie du fait que le dispositif de pliage occupe une position déterminée sur la plieuse-colleuse, alors que les dimensions des découpes de carton peuvent varier sensiblement. On peut aussi avoir des découpes qui ont des pattes à replier alignées transversalement, mais dont les longueurs de pattes sont différentes. Ceci suppose d'avoir deux dispositifs sur un support transversal commun, mais qui sont réglés en fonction des longueurs respectives des pattes.Such a solution is however relatively complex and therefore expensive. This complexity is largely due to the fact that the folding device occupies a specific position on the folder-gluer, while the dimensions of the cardboard blanks can vary substantially. It is also possible to have cutouts that have legs to fold aligned transversely, but whose leg lengths are different. This supposes to have two devices on a common transversal support, but which are adjusted according to the respective lengths of the tabs.
Le but de la présente invention est de remédier, au moins en partie, aux inconvénients des solutions susmentionnées.The object of the present invention is to overcome, at least in part, the disadvantages of the aforementioned solutions.
A cet effet, la présente invention a pour objet un dispositif de pliage de pattes de découpes de boîtes ayant des lignes de refoulage disposées transversalement à la direction de déplacement des découpes, pour plieuse-colleuse, selon la revendication 1.To this end, the subject of the present invention is a device for folding box cut tabs having upsetting lines arranged transversely to the direction of movement of the blanks, for folder-gluer, according to
Ce dispositif est simple. Il peut être monté sur tout support approprié de la plieuse-colleuse, qui peut trouver place à l'intérieur de tout espace laissé libre dans la machine. En effet, le dispositif étant entièrement autonome, le support sur lequel il est monté n'a pas d'autre fonction étant donné que le dispositif est entraîné par un moteur synchronisé avec le mécanisme d'entraînement de la plieuse-colleuse et non directement par ce mécanisme d'entraînement.This device is simple. It can be mounted on any suitable medium of the folder-gluer, which can fit inside any space left free in the machine. Indeed, the device being completely autonomous, the support on which it is mounted has no other function since the device is driven by a motor synchronized with the drive mechanism of the folder-gluer and not directly by this drive mechanism.
On verra au cours de la description qui suit qu'en raison de sa grande facilité à être monté n'importe où il y a de la place entre les bâtis de la plieuse-colleuse, ce dispositif offre de nouvelles possibilités d'applications par rapport aux dispositifs de pliage de l'art antérieur.It will be seen from the following description that because of its great ease to be mounted anywhere there is room between the frames of the folder-gluer, this device offers new possibilities of applications compared to the folding devices of the prior art.

Le dispositif selon l'invention comporte un boîtier 1 de forme allongée présentant deux grandes faces parallèles reliées par des faces latérales relativement étroites. Une des grandes faces parallèles de ce boîtier 1 porte un moteur d'entraînement 2 dont l'arbre s'étend à l'intérieur de ce boîtier. Une poulie crantée 3, située dans le boîtier 1, est clavetée à l'extrémité de cet arbre. Cette poulie crantée 3 est en prise avec une courroie crantée 4 formant une boucle sans fin en prise avec une seconde poulie crantée (cachée par les parois du boîtier 1), solidaire d'un arbre 5 monté à rotation dans les parois du boîtier 1 et dont une extrémité fait saillie hors de ce boîtier 1.The device according to the invention comprises a
Dans le présent exemple, l'extrémité de l'arbre 5 porte deux bras de pliage 6 en forme de crochets, disposés symétriquement par rapport à un plan contenant l'axe longitudinal de l'arbre 5. Ces bras de pliage 6 sont solidaires de l'arbre 5, de sorte qu'ils sont entraînés par lui lorsque le moteur 2 entraîne la courroie 4 en prise avec la poulie crantée 3. Il est évident qu'en adaptant la vitesse de rotation du moteur 2 on pourrait imaginer de n'utiliser qu'un seul bras de pliage en forme de crochet.In the present example, the end of the
Les deux faces latérales allongées du boîtier 1 présentent chacune une coulisse en queue d'aigle 7, 8. Ces coulisses 7, 8 servent sélectivement au montage du boîtier sur la plieuse-colleuse dont on a représenté sur les figures 2 et 3 une portion de deux parties latérales du bâti B et du mécanisme d'entraînement 9 des découpes de boîtes, ainsi qu'une traverse de support 10 de ce dispositif qui s'étend entre les deux parties latérales du bâti B. Une des coulisses 7, 8 du boîtier 1 est destinée à recevoir des moyens de liaison à la traverse de support 10 qui comportent essentiellement une plaque de liaison 11 associée d'une part à des coulisseaux à vis 12 qui s'engagent dans une des coulisses 7, 8 et permettent de serrer la plaque de liaison 11 dans la position désirée le long de la coulisse 7 ou 8. Cette plaque de liaison 11 porte encore, d'autre part, deux bras de serrage 13 destinés à sa fixation le long de la traverse de support 10. Cette traverse de support 10 présente une section polygonale, carrée dans l'exemple représenté, pour permettre de définir l'orientation de la plaque de liaison 11 par rapport à l'axe longitudinal de la traverse de support 10.The two elongated lateral faces of the
Les coulisseaux à vis 12 sont alignés selon un axe perpendiculaire à l'axe sur lequel les bras de serrage sont alignés, de manière à former des moyens de fixation réglables selon deux directions orthogonales.The
Grâce au dispositif décrit, le boîtier 1 présente donc une possibilité de réglage selon deux degrés de liberté, l'un transversal, par rapport à la traverse de support 10 en prise avec les bras de serrage 13, l'autre vertical le long de l'une des coulisses 7, 8 en prise avec les coulisseaux à vis 12.Thanks to the device described, the
Pour assurer la synchronisation entre le moteur d'entraînement 2, des bras de pliage 6, et le mécanisme d'entraînement 9 des découpes de boîtes dans la plieuse-colleuse, le dispositif selon l'invention comporte une cellule laser 14 destinée à détecter le passage à un endroit de référence précis d'un bord arrière de chaque découpe de boîte. Cette cellule laser 14 est reliée à un boîtier de commande 15 du moteur d'entraînement 2 (figures 2 et 3). Les moyens de synchronisation du dispositif comportent encore un codeur 16 relié d'une part, par une liaison desmodromique (c'est-à-dire par une liaison telle que la vitesse de rotation du codeur 16 provoque une vitesse bien déterminée pour la rotation du mécanisme d'entraînement 9) au mécanisme d'entraînement 9 des découpes de boîtes et d'autre part, par une connexion électrique, au boîtier de commande 15 du moteur d'entraînement 2. Ces informations permettent de commander le moteur 2 de manière synchrone avec la vitesse d'avance des découpes de boîtes et leur fréquence de passage à l'endroit de détection qui est fonction de la longueur des découpes de boîtes dans le sens de leur défilement F dans la plieuse-colleuse.To ensure synchronization between the
Le boîtier de commande 15 doit encore recevoir des informations sur les caractéristiques des découpes pour assurer la programmation du moteur d'entraînement. Ces informations sont introduites par l'opérateur de la machine. Toutefois, le mode de programmation ne faisant pas partie de la présente invention, il n'est pas nécessaire de le décrire ici.The
Comme on le comprend aisément de la description qui précède, le dispositif de pliage décrit est autonome quant à son fonctionnement, ce qui permet de le disposer pratiquement n'importe où il y a de la place libre sur une plieuse-colleuse. En outre, son mode de liaison permet de régler sa position en fonction de la longueur des pattes des découpes de boîtes à plier. Il est même possible de placer deux dispositifs de pliage de manière à ce qu'ils plient deux pattes dont les lignes de refoulage sont alignées transversalement, mais dont les longueurs sont différentes, en variant simplement la distance h entre l'axe de l'arbre 5 des bras de pliage 6 et le plan P de la trajectoire de déplacement des découpes de boîtes (figures 4 et 5), en faisant coulisser le boîtier 1 par rapport à la plaque de liaison 11 et en serrant les coulisseaux à vis 12 lorsque la distance h désirée est obtenue. Une tabelle indiquant la valeur de h en fonction de la longueur des pattes des découpes peut être établie à l'intention de l'opérateur.As is readily understood from the foregoing description, the folding device described is autonomous in its operation, which allows it to be disposed practically anywhere there is free space on a folder-gluer. In addition, its connection mode allows to adjust its position according to the length of the legs of the cutouts of boxes to bend. It is even possible to place two folding devices so that they fold two tabs whose crease lines are aligned transversely, but whose lengths are different, simply by varying the distance h between the axis of the tree. 5 of the
A titre d'exemple, les figures 4 et 5 montrent les positions relatives de l'axe de l'arbre 5 des bras de pliage 6 pour des longueurs de pattes de découpes de boîte de 20 à 25 mm, respectivement 71 à 100 mm, avec des bras de pliage 6 de 100 mm de rayon.By way of example, FIGS. 4 and 5 show the relative positions of the axis of the
Une autre possibilité offerte par le dispositif objet de la présente invention, consiste à utiliser les bras de pliage 6 pour tenir la ligne transversale de refoulage autour de laquelle la patte est pliée du côté intérieur du pli. En effet, si, lors du pliage, la ligne de refoulage, sous l'effet de la force qui s'exerce sur la patte de pliage du côté externe au pli, prend une forme convexe du côté interne du pli, le pliage de la patte n'est plus possible. Ce risque est éliminé si la ligne de refoulage est tenue au début de l'opération de pliage. Ceci est rendu possible par le dispositif objet de la présente invention étant donné que rien n'empêche de placer ce dispositif au-dessus du plan P de la trajectoire des découpes de boîtes.Another possibility offered by the device that is the subject of the present invention consists in using the folding
