Description

La présente invention est relative à un dispositif de décalage de la position latérale d'un outil monté sur un arbre tournant dans la station d'encochage au sein d'une machine transformant des plaques de carton épais ou ondulé en boîtes. Pour mémoire, cette station effectue, dans le sens de déplacement des plaques, une première opération de refoulage préparant des lignes parallèles pour pliages ultérieurs et une seconde opération de découpe d'encoches dans les bords amont et aval de la plaque, situés normalement dans le prolongement des lignes précédemment marquées, lesquelles encoches définissent les futures parties rabattantes de la boîte. Pour assurer un déroulement régulier de cette usinage, une opération d'entraînement est fréquemment intercalée entre les deux opérations mentionnées précédemment.The present invention relates to a device for shifting the lateral position of a tool mounted on a rotating shaft in the notching station within a machine transforming thick or corrugated cardboard plates into boxes. For the record, this station performs, in the direction of movement of the plates, a first upsetting operation preparing parallel lines for subsequent folding and a second operation of cutting notches in the upstream and downstream edges of the plate, normally located in the extension of the previously marked lines, which notches define the future folding parts of the box. To ensure a smooth progress of this machining, a drive operation is frequently interposed between the two operations mentioned above.

Pour chacune de ces opérations, les éléments en plaque passent entre des paires d'outils circulaires : un outil actif et sa contrepartie, montés en correspondance sur deux arbres horizontaux, un supérieur et un inférieur, qui sont disposés transversalement au sens de déplacement des éléments. La station comprend ainsi usuellement trois paires verticales d'arbres : une section de refoulage à l'entrée, une section médiane d'entrainement et une section de refente à la sortie. Cette station comprend de plus des mécanismes permettant de déplacer latéralement ensemble chaque triplet de paires d'outils situé le long d'une même ligne parallèle au sens du déplacement des éléments, ce qui permet de maintenir, lors des réglages relatifs au format des boîtes à fabriquer, les outils de refente dans l'axe des outils de refoulage.For each of these operations, the plate elements pass between pairs of circular tools: an active tool and its counterpart, mounted in correspondence on two horizontal shafts, one upper and one lower, which are arranged transversely to the direction of movement of the elements . The station thus usually comprises three vertical pairs of shafts: a discharge section at the inlet, a middle drive section and a slit section at the outlet. This station also includes mechanisms for moving laterally together each triplet of pairs of tools located along the same line parallel to the direction of movement of the elements, which makes it possible to keep, during adjustments relating to the format of the boxes to be manufactured, the slitting tools in the axis upsetting tools.

Chacun des ces mécanismes est essentiellement constitué d'une plaque maîtresse pour chaque triplet d'outils supérieur ou inférieur, cette plaque présentant sur son pourtour des moyens de guidage de la position latérale des outils sur leur arbre respectif. Un moyen de guidage peut être, par exemple, une encoche en arc-de-cercle ayant effet de fourche venant s'engager dans la rainure transversale de l'outil circulaire qui peut ainsi continuer à tourner librement entraîné par son arbre. Un autre moyen de guidage peut être constitué d'une encoche en arc-de-cercle plus large complétée par des doigts ou patins rapportés qui, eux, s'engagent dans la rainure transversale de l'outil. D'autres formes de réalisation sont encore possibles, notamment par l'emploi d'un disque d'usure saillant tournant avec l'outil et pris entre deux patins d'usure montés de part et d'autre de la plaque maîtresse.Each of these mechanisms essentially consists of a master plate for each triplet of upper or lower tools, this plate having on its periphery means for guiding the lateral position of the tools on their respective shafts. A guide means can be, for example, a notch in a semicircle having the effect of a fork coming to engage in the transverse groove of the circular tool which can thus continue to rotate freely driven by its shaft. Another guiding means can consist of a notch in a wider semicircle completed by added fingers or pads which, in turn, engage in the transverse groove of the tool. Other embodiments are also possible, in particular by the use of a protruding wear disc rotating with the tool and caught between two wear pads mounted on either side of the master plate.

Chaque plaque est tenue verticalement dans le sens de déplacement des feuilles par deux arbres au moins : un arbre lisse de guidage passant dans une fourche de la plaque que complète un bloc-guide supérieur et un inférieur en contact avec cet arbre, et un arbre fileté passant au travers d'un écrou à billes aussi solidaire de cette plaque. Ainsi, en tournant grâce à un moteur électrique l'arbre fileté qui agit sur l'écrou à billes de la plaque, il est possible de déplacer latéralement cette plaque, c'est-à-dire vers la droite ou vers la gauche, tout en la maintenant en tout point verticale orientée dans le sens de déplacement des feuilles. Cette plaque entraîne alors simultanément le triplet d'outils supérieurs qui reste donc toujours le long d'une même ligne. Un dispositif analogue inférieur déplace en correspondance le triplet d'outils de contre-partie.Each plate is held vertically in the direction of movement of the sheets by at least two shafts: a smooth guide shaft passing through a fork of the plate which is completed by an upper and lower guide block in contact with this shaft, and a threaded shaft passing through a ball nut also integral with this plate. So, by turning thanks to an electric motor the threaded shaft which acts on the ball nut of the plate, it is possible to move this plate laterally, i.e. to the right or to the left, while maintaining it at all points vertical oriented in the direction of movement of the sheets. This plate then simultaneously drives the triplet of upper tools which therefore always remains along the same line. A lower analog device moves the triplet of counterpart tools in correspondence.

On constate de manière évidente que, pour une station d'encochage comprenant six rangées parallèles d'outils d'usinage, les dispositifs supérieurs de réglage de position d'outils nécessitent au moins un arbre de guidage commun et trois arbres filetés de réglage si les formes découper présentent une symétrie par rapport à l'axe médian de la station, ou six arbres individuels, trois venant de chaque côté, dans le cas contraire. Il faut aussi prévoir un nombre identique d'arbres pour la partie inférieure.It is evident that, for a notching station comprising six parallel rows of machining tools, the upper devices for adjusting the position of the tools require at least one common guide shaft and three threaded adjusting shafts if the Cut shapes have symmetry about the center line of the station, or six individual trees, three coming from each side, otherwise. It is also necessary to provide an identical number of trees for the lower part.

Il s'est toutefois avéré utile, par la suite, de pouvoir légèrement décaler latéralement, sur une faible distance, l'outil de refoulage par rapport à l'outil de refente de telle sorte que la future pliure s'effectue un peu plus proche de l'un des rabattants que de l'autre. En effet, lors du pliage de la boîte, il advient un moment où un premier rabattant doit être replié vers l'intérieur au milieu des trois autres encore verticaux. Dans ce cas, si les pliages sont exactement centrés par rapport aux fentes, il suffit que l'un des rabattants adjacents soit légèrement oblique pour que l'opération soit malaisée. A l'inverse, si ce pliage est effectué exactement dans le prolongement du bord du rabattant adjacent, donc que le refoulage ait été effectué dans le prolongement du côté de la fente, alors la largeur de cette même fente constitue lors de cette opération de pliage une marge de sécurité disponible de part et d'autre.It has however proved useful, thereafter, to be able to slightly offset laterally, over a short distance, the upsetting tool with respect to the slitting tool so that the future bending takes place a little closer of one of the flaps than of the other. Indeed, when folding the box, there comes a time when a first flap must be folded inward in the middle of the other three still vertical. In this case, if the folds are exactly centered in relation to the slots, it suffices that one of the adjacent flaps is slightly oblique so that the operation is difficult. Conversely, if this folding is carried out exactly in the extension of the edge of the adjacent flap, therefore that the pushing has been carried out in the extension of the side of the slot, then the width of this same slot constitutes during this folding operation a safety margin available on both sides.

Une première solution consisterait a prévoir, dans la partie supérieure seulement, pour chaque triplet d'outils appartenant à une même ligne, un premier dispositif de positionnement de l'outil de refoulage seulement et un second dispositif pour le positionnement de l'outil de refente et de l'outil d'entraînement éventuellement associé. Cette solution conduirait à doubler le nombre d'arbres de guidage et d'arbres filetés alourdissant d'autant le poids de cette station, augmentant son coût alors que les corrections sont faibles par rapport aux déplacements initiaux.A first solution would consist in providing, in the upper part only, for each triplet of tools belonging to the same line, a first device for positioning the upsetting tool only and a second device for positioning the slitting tool and any associated driving tool. This solution would result in doubling the number of guide shafts and threaded shafts thereby increasing the weight of this station, increasing its cost while the corrections are small compared to the initial displacements.

La solution actuellement retenue consiste à démonter la partie active de l'outil refouleur du corps fixé sur l'arbre, et à le remonter en intercalant latéralement une ou plusieurs cales sous la forme de disque transversal d'épaisseur standardisée. Cette solution implique toutefois des temps de réglage très longs lors du passage de la production d'un type de boîtes à un autre. En effet, après chaque essai, l'opérateur doit démonter le ou les outils fautifs pour changer les cales, puis poursuivre ses essais jusqu'à un résultat final satisfaisant.The currently selected solution consists in dismantling the active part of the pressure tool from the body fixed on the shaft, and reassembling it by inserting laterally one or more wedges in the form of a transverse disc of standardized thickness. This solution however involves very long adjustment times during the transition from production from one type of box to another. Indeed, after each test, the operator must dismantle the faulty tool or tools to change the shims, then continue his tests until a satisfactory final result.

Le but de la présente invention est un dispositif permettant un décalage précis et aisé de la position latérale de l'outil refouleur par rapport à la ligne d'action de l'outil refendeur correspondant, ou de l'outil refendeur par rapport à l'outil refouleur. Un tel dispositif doit permettre un déplacement d'une masse importante sur une faible distance de manière non saccadée de telle sorte que l'arrêt en la position choisie puisse être facilement réalisé. Bien évidemment, ce dispositif doit rester de conception simple pour assurer sa solidité donc fiabilité.The object of the present invention is a device allowing precise and easy shifting of the lateral position of the delivery tool with respect to the line of action of the corresponding splitting tool, or of the splitting tool with respect to the repressor tool. Such a device must allow a displacement of a large mass over a short distance in a jerky manner so that stopping in the chosen position can be easily achieved. Obviously, this device must remain simple in design to ensure its solidity and therefore reliability.

Ces buts sont réalisés grâce à un dispositif de décalage de la position latérale d'un outil de refoulage dans la station d'encochage située dans une machine usinant des éléments en plaque. Cette station comprend au moins des outils de refoulage et de contre-partie montés en correspondance sur une première paire verticale d'arbres parallèles horizontaux disposés transversalement par rapport au sens de déplacement des éléments en plaque. Cette station comprend aussi des outils de refente et de contre-partie montés sur une autre paire d'arbres disposée en aval de manière analogue à la première. Cette station comprend en outre des mécanismes de positionnement latéral simultané de tous les outils supérieurs situés sur une même ligne parallèle au sens de déplacement des éléments. Dans cette station, chaque mécanisme est essentiellement constitué d'une plaque maîtresse maintenue verticale orientée dans le sens de déplacement des éléments par deux arbres transversaux au moins : un de guidage et un fileté, ce dernier pouvant imprimer à la plaque un déplacement latéral, laquelle plaque maîtresse présente sur son pourtour des moyens de guidage latéral des outils respectifs. Selon l'invention, les moyens de guidage latéral pour un outil devant être décalé à volonté par rapport aux autres outils sont situés sur une plaque secondaire rattachée à la plaque maîtresse par des moyens mécaniques permettant d'imprimer à cette plaque secondaire un mouvement de translation orthogonal à la plaque maîtresse tout en la maintenant en tout point parallèle à cette même plaque maîtresse.These aims are achieved by means of a device for shifting the lateral position of a delivery tool in the notching station located in a machine machining plate elements. This station comprises at least tools for upsetting and counterpart mounted in correspondence on a first vertical pair of horizontal parallel shafts arranged transversely with respect to the direction of movement of the plate elements. This station also includes slitting and counterpart tools mounted on another pair of shafts arranged downstream in a manner similar to the first. This station also includes mechanisms for lateral positioning of all the upper tools located on the same line parallel to the direction of movement of the elements. In this station, each mechanism essentially consists of a master plate kept vertical oriented in the direction of movement of the elements by at least two transverse shafts: one for guiding and one thread, the latter being able to impart a lateral displacement to the plate, which centerpiece present on his periphery of the lateral guide means of the respective tools. According to the invention, the lateral guide means for a tool to be offset at will relative to the other tools are located on a secondary plate attached to the master plate by mechanical means making it possible to impart a translational movement to this secondary plate. orthogonal to the master plate while keeping it at all points parallel to this same master plate.

Selon un premier mode de réalisation, les moyens mécaniques comprennent :
- une broche horizontale fixée orthogonalement à la plaque maîtresse et présentant un orifice transversal vertical,
- un bloc métallique solidaire de la plaque secondaire, tous deux etant traversés par un orifice orthogonal à la plaque secondaire leur permettant d'être engagés sur la broche le long de laquelle ils peuvent coulisser. Ce bloc présente de plus un orifice vertical croisant la broche au niveau de son orifice tranversal vertical,
- une tige verticale dont le pivot inférieur est engagé dans l'orifice transversal vertical de la broche, dont la partie inférieure située dans l'orifice vertical du bloc est cylindrique excentrée et dont la partie supérieure terminée par une tête est maintenue, mobile en rotation, à la plaque maîtresse par un support. Alors, tout mouvement de rotation imprimé au niveau de la tête à la tige se traduit par interaction de la partie cylindrique excentrée dans l'orifice vertical du bloc en un mouvement de translation latérale de l'ensemble bloc/plaque secondaire le long de la broche.According to a first embodiment, the mechanical means comprise:
- a horizontal pin fixed orthogonally to the master plate and having a vertical transverse orifice,
- A metal block secured to the secondary plate, both being crossed by an orifice orthogonal to the secondary plate allowing them to be engaged on the spindle along which they can slide. This block also has a vertical orifice crossing the spindle at its vertical transverse orifice,
- a vertical rod, the lower pivot of which is engaged in the vertical transverse orifice of the spindle, the lower part of which is located in the vertical orifice of the block is eccentric cylindrical and the upper part of which ends in a head is held, movable in rotation , to the main plate by a support. So, any rotational movement imparted at the level of the head to the rod results in interaction of the cylindrical part eccentric in the vertical orifice of the block in a lateral translational movement of the block / secondary plate assembly along the spindle.

Il s'est alors avéré utile de munir la tête de la tige verticale en son extrémité amont d'une barrette la traversant verticalement. Cette barrette peut être repoussée vers le bas par des moyens de rappel pour engager son extrémité inférieure dans des orifices présents sur la face supérieure du support. Cette barrette peut aussi être complétée en son extrémité supérieure par un bouton permettant de la soulever contre l'action des moyens de rappel. Ainsi, cette barrette permet de bloquer en des valeurs prédéterminées la position angulaire de la tête par rapport au support donc la position latérale de la plaque secondaire par rapport à la plaque maîtresse.It then proved useful to provide the head of the vertical rod at its upstream end with a bar crossing it vertically. This bar can be pushed back down by return means to engage its lower end in holes present on the upper face of the support. This bar can also be completed at its upper end by a button allowing it to be raised against the action of the return means. Thus, this bar makes it possible to block in predetermined values the angular position of the head relative to the support therefore the lateral position of the secondary plate relative to the master plate.

Selon un autre mode de réalisation, les moyens mécaniques comprennent:
- une broche horizontale fixée orthogonalement à la plaque maîtresse (ou à la plaque secondaire)
- au moins une vis traversant othogonalement la plaque maîtresse (ou secondaire), la partie filetée ou hélicoïdale étant située du côté de la broche, la partie lisse étant tenue mobile en rotation dans la plaque maîtresse (ou secondaire) d'une part par la tête et d'autre part par un épaulement médian ou par une rondelle.
- une plaque secondaire (ou maîtresse) présentant un orifice lisse en correspondance de la broche et un orifice taraudé en correspondance de la vis de telle sorte que, une fois cette plaque secondaire engagée sur cette vis et broche (ou une fois la broche et la partie filetée de la vis engagées dans les orifices correspondants de la plaque maîtresse), toute rotation combinée de la ou des vis par action sur la tête provoque une translation orthogonal guidée par la broche de la plaque secondaire par rapport à la plaque maîtresse.According to another embodiment, the mechanical means comprise:
- a horizontal pin fixed orthogonally to the master plate (or to the secondary plate)
- at least one screw othogonally passing through the master (or secondary) plate, the threaded or helical part being located on the side of the spindle, the smooth part being held movable in rotation in the master (or secondary) plate on the one hand by the head and on the other hand by a median shoulder or by a washer.
- a secondary plate (or master) having a smooth orifice in correspondence of the spindle and a tapped orifice in correspondence of the screw so that, once this secondary plate is engaged on this screw and spindle (or once the spindle and the threaded part of the screw engaged in the corresponding orifices of the master plate), any combined rotation of the screw or screws by action on the head causes an orthogonal translation guided by the spindle of the secondary plate relative to the master plate.

Avantageusement alors, le pourtour de la tête de vis présente une série d'orifices permettant le maintien d'une position angulaire de la vis au moyen d'une bille poussée par un moyen de rappel hors de son logement situé proche de la tête.Advantageously then, the periphery of the screw head has a series of orifices allowing the angular position of the screw to be maintained by means of a ball pushed by a return means out of its housing located close to the head.

L'invention est décrite ci-après de façon plus détaillé à l'aide d'exemples d'exécution sans caractère limitatif illustrés aux dessins annexés, dans lesquelles :

  • - la figure 1 est une vue de perspective d'un premier mode de réalisation du dispositif tel qu'observé de l'entrée de la station d'encochage,
  • - les figures 2a à 2c sont des vues en coupe selon le plan II de la figure 1 illustrant la position de l'ensemble bloc/plaque secondaire en fonction de la poignée d'action donc de la position de la tige verticale.
  • - la figure 3 est une vue en perspective d'un second mode de réalisation du dispositif.
The invention is described below in more detail with the aid of non-limiting exemplary embodiments illustrated in the accompanying drawings, in which:
  • FIG. 1 is a perspective view of a first embodiment of the device as seen from the entrance to the notching station,
  • - Figures 2a to 2c are sectional views along plane II of Figure 1 illustrating the position of the block / secondary plate assembly as a function of the action handle, therefore of the position of the vertical rod.
  • - Figure 3 is a perspective view of a second embodiment of the device.

Sur la figure 1 sont représentés un outil refouleur 60 sur un arbre 40 avec sa contre-partie 75 montée sur un arbre 50. Plus en aval, on peut observer la face droite de l'outil d'entraînement supérieur 26 montée sur un arbre 20. Sa contre-partie ainsi que les outils plus en aval de refente ne sont pas représentés pour une meilleure clarté du dessin.In FIG. 1 are shown a discharge tool 60 on a shaft 40 with its counterpart 75 mounted on a shaft 50. Further downstream, we can observe the right face of the upper drive tool 26 mounted on a shaft 20 Its counterpart as well as the tools further downstream of the slitting are not shown for better clarity of the drawing.

Une plaque maîtresse 100 de contrôle de position latérale des outils supérieurs est tenue verticale orientée dans le sens de déplacement des feuilles par deux arbres : un arbre de guidage 30 et un arbre fileté 10. Pour améliorer la clarté de la figure 1, l'arbre de guidage 30 a été représenté sous une forme tronçonnée. Normalement, cet arbre est continu lisse et chromé pour permettre aux guides 110 de la fourche de guidage 105 de la plaque maîtresse 100 de glisser aisément le long de cet arbre. Deux écrous à billes 108 sont fixés de part et d'autre de la noix 109 de la plaque maîtresse 100. L'arbre fileté passe au travers de ces deux écrous à billes 108, lesquels écrous imposent la plaque maîtresse 100 son maintien vertical orthogonal à l'arbre fileté 10. De plus, lorsque l'arbre fileté 10 tourne dans un sens ou dans un autre, ces écrous à billes transmettent à la plaque 100 un déplacement en correspondance vers la droite ou vers la gauche.A master plate 100 for controlling the lateral position of the upper tools is held vertically oriented in the direction of movement of the sheets by two shafts: a guide shaft 30 and a threaded shaft 10. To improve the clarity of FIG. 1, the shaft guide 30 has been shown in sectioned form. Normally, this shaft is continuous smooth and chrome-plated to allow the guides 110 of the guide fork 105 of the master plate 100 to slide easily along this shaft. Two ball nuts 108 are fixed on either side of the nut 109 of the master plate 100. The threaded shaft passes through these two ball nuts 108, which nuts impose the master plate 100 on its vertical support orthogonal to the threaded shaft 10. In addition, when the threaded shaft 10 rotates in one direction or another, these ball nuts transmit to the plate 100 a corresponding displacement to the right or to the left.

Cette plaque maîtresse 100 présente sur son pourtour plusieurs encoches en forme d'arc-de-cercle ayant effet de fourche qui s'engagent dans une rainure circulaire de l'outil correspondant. La fourche 107 de l'outil refendeur et la fourche 106 engagée dans l'outil d'entraînement supérieur sont visibles sur la figure 1. Dans le dispositif selon l'invention, la fourche de la plaque maîtresse 100 vis-à-vis de l'outil refouleur est substituée par une partie élargie n'entrant pas en contact avec cet outil refouleur 60. A la place, la rainure 70 de l'outil refouleur 60 est engagée par la fourche 226 appartenant à une plaque secondaire 225. Cette plaque secondaire 225 est portée avec son bloc 220 solidaire par une broche 130. Cette broche 130 est solidement fixée orthogonalement à la plaque maîtresse 100 vis-à-vis de l'outil refouleur 60.This master plate 100 has on its periphery several notches in the form of a semicircle having fork effect which engage in a circular groove of the corresponding tool. The fork 107 of the splitting tool and the fork 106 engaged in the upper drive tool are visible in FIG. 1. In the device according to the invention, the fork of the master plate 100 with respect to the the delivery tool is replaced by an enlarged part which does not come into contact with this delivery tool 60. Instead, the groove 70 of the delivery tool 60 is engaged by the fork 226 belonging to a secondary plate 225. This secondary plate 225 is carried with its block 220 secured by a spindle 130. This spindle 130 is securely fixed orthogonally to the master plate 100 with respect to the delivery tool 60.

La broche 130 présente un orifice transversal vertical 135. De même, le bloc 220 présente un orifice 222 vertical croisant la broche au niveau de l'orifice transversal 135. Un support 205 est par ailleurs fixé solidairemment contre la plaque maîtresse à la verticale de la broche 130. Ce support 205 tient par le haut une tige verticale 208 dont le pivot 210 à l'extrémité inférieure est engagé dans l'orifice 135 de la broche 130, et dont la partie 209 se situe l'intérieur de l'orifice 222 du bloc 220. Cette tige verticale 208 est terminée en son extrémité supérieure par une tête 207. Cette tête 207 est munie d'une part, côté amont, d'une poignée 212 et d'autre part, côté aval, d'une extension au travers de laquelle passe une barrette verticale dont seul le bouton supérieur 213 est visible. A l'intérieur de cette extension, un moyen de rappel tel qu'un ressort repousse cette barrette vers le bas. Par exemple, ce ressort peut agir entre un épaulement inférieur de la barrette et la face supérieure du logement contenant ce ressort et cette barrette. Cette barrette peut s'engager dans des orifices 211 de blocage présents sur la face supérieure du support 205 bloquant ainsi la position angulaire de la tête 207 par rapport au support 205.The spindle 130 has a vertical transverse orifice 135. Likewise, the block 220 has a vertical orifice 222 crossing the spindle at the level of the transverse orifice 135. A support 205 is moreover fixed solidly against the master plate vertically spindle 130. This support 205 holds a vertical rod 208 from above, the pivot 210 at the lower end of which is engaged in the orifice 135 of the spindle 130, and the part 209 of which is located inside the orifice 222 of the block 220. This vertical rod 208 is terminated at its upper end by a head 207. This head 207 is provided on the one hand, upstream side, with a handle 212 and on the other hand, downstream side, an extension through which passes a vertical bar of which only the upper button 213 is visible. Inside this extension, a return means such as a spring pushes this bar down. For example, this spring can act between a lower shoulder of the bar and the upper face of the housing containing this spring and this bar. This bar can engage in blocking orifices 211 present on the upper face of the support 205, thus blocking the angular position of the head 207 relative to the support 205.

L'interaction de la partie cylindrique excentrée 209 de la tige verticale 208 dans l'orifice 222 du bloc 220 sera mieux comprise à la lecture des figures 2a, b et c présentant, vu en coupe transversale selon le plan II de la figure 1, le détail des pièces. On y reconnaît notamment, sous-jacent, un pivot 210 engagé dans la broche 130 elle-même solidaire de la plaque maîtresse 100. On reconnaît de plus, coulissant le long de cette broche 130, une partie de la plaque secondaire 225 associée au bloc 220. La partie cylindrique 209 est excentrée d'une distance d par rapport à l'axe vertical du pivot 210 et de la tige verticale 208. La section transversale de l'orifice 222 du bloc 220 n'est pas exactement circulaire mais constituée de deux demi-cercles de rayon légèrement supérieur à celui de la partie cylindrique 209, demi-cercles écartés dans le sens parallèle à la plaque secondaire d'une distance d. Tel qu'illustré sur la figure 2a, le bord inférieur de cet orifice 222 correspond à la position basse de la partie cylindrique 209 lorsque la poignée est tournée complètement vers la droite ou vers la gauche. Réciproquement, le bord supérieur de cet orifice 222 correspond à la position de la partie cylindrique 209 lorsque le levier 212 se trouve parallèle à la plaque secondaire 225 tel qu'illustré sur la figure 2b.The interaction of the eccentric cylindrical part 209 of the vertical rod 208 in the orifice 222 of the block 220 will be better understood on reading FIGS. 2a, b and c having, seen in cross section along the plane II of FIG. 1, the detail of the parts. We recognize in particular, underlying, a pivot 210 engaged in the spindle 130 itself integral with the master plate 100. It is further recognized, sliding along this spindle 130, part of the secondary plate 225 associated with the block 220. The cylindrical part 209 is offset by a distance d relative to the vertical axis of the pivot 210 and the vertical rod 208. The cross section of the orifice 222 of the block 220 is not exactly circular but consists of two semicircles of radius slightly greater than that of the cylindrical part 209, semicircles spaced apart in the direction parallel to the secondary plate by a distance d. As illustrated in FIG. 2a, the lower edge of this orifice 222 corresponds to the low position of the cylindrical part 209 when the handle is turned completely to the right or to the left. Conversely, the upper edge of this orifice 222 corresponds to the position of the cylindrical part 209 when the lever 212 is parallel to the secondary plate 225 as illustrated in FIG. 2b.

Comme on le constatera aisément à la vue des figures 1 et 2, toute action sur la poignée 212 après levée du bouton 213 se traduit par une rotation de la tige verticale 208 autour du pivot du 210 et à l'intérieur de son support 205. Cette rotation de la tige 208 implique une rotation de la partie cylindrique 209 poussant d'un côté ou de l'autre le bloc 220, donc déplaçant la plaque secondaire 225 par rapport à la plaque maîtresse 100. L'opérateur accomplit usuellement cette rotation jusqu'à pouvoir réengager la barrette dans un nouvel orifice 211 du support 205. Ce déplacement latéral de la plaque secondaire 225 a induit un déplacement similaire de l'outil refouleur 60 de par l'engagement de la fourche 226 à l'intérieur de la rainure 70. La contre-partie 75 étant suffisamment large par rapport au faible décalage imprimé, il n'est pas nécessaire de reconsidérer sa position.As will be readily seen from the view of FIGS. 1 and 2, any action on the handle 212 after lifting of the button 213 results in a rotation of the vertical rod 208 around the pivot of the 210 and inside its support 205. This rotation of the rod 208 implies a rotation of the cylindrical part 209 pushing on one side or the other the block 220, therefore moving the secondary plate 225 relative to the master plate 100. The operator usually accomplishes this rotation up to '' to be able to re-engage the bar in a new orifice 211 of the support 205. This lateral displacement of the secondary plate 225 has induced a similar displacement of the discharge tool 60 by the engagement of the fork 226 inside the groove 70. The counterpart 75 being sufficiently wide with respect to the small printed offset, it is not necessary to reconsider its position.

Sur la figure 3 est illustré en perspective un second mode de réalisation du dispositif selon l'invention. Les pièces similaires à celles décrites précédemment portent des références identiques. On y reconnaît notamment un outil refouleur 60 porté par l'arbre 40 et sa contre-partie 75 porté par l'arbre 50. La plaque maîtresse 101 est tenue verticalement dans le sens de déplacement des éléments en plaque par un arbre de guidage 30 et un arbre fileté 10 agissant sur la noix 109 au travers de deux écrous a billes 108.In Figure 3 is illustrated in perspective a second embodiment of the device according to the invention. Parts similar to those described above bear identical references. In particular, there is recognized a discharge tool 60 carried by the shaft 40 and its counterpart 75 carried by the shaft 50. The master plate 101 is held vertically in the direction of movement of the plate elements by a guide shaft 30 and a threaded shaft 10 acting on the nut 109 through two ball nuts 108.

Sur cette figure 3, sont également représentés, a titre nullement limitatif, deux autres modes de guidage latéral d'outil par la plaque maîtresse 101, à savoir : le guidage de l'outil d'entraînement 28 et de l'outil de refente 124. L'outil 28 présente un disque circulaire saillant 27 pris entre deux patins d'usure 120 situés de part et d'autre de la plaque 101. L'outil 124 présente une rainure circulaire transversale 127 similaire à la rainure 70 de l'outil 60. Mais dans ce cas, l'encoche 125 en forme d'arc-de-cercle de la plaque maîtresse 101 est élargie, et ce sont deux doigts d'entraînement 126 fixés sur le pourtour de cette encoche 125 qui engagent l'outil 124 dans la rainure 127. Comme on le comprendra aisément, l'avantage de ces autres modes de guidage est que les parties pouvant s'user au cours du fonctionnement peuvent être remplacées.In this FIG. 3, two other modes of lateral tool guiding by the master plate 101, namely: guiding the driving tool 28 and the slitting tool 124. The tool 28 has a projecting circular disc 27 caught between two wear pads 120 located on either side of the plate 101. The tool 124 has a transverse circular groove 127 similar to the groove 70 of the tool 60. But in this case, the notch 125 in the form of an arc of a circle of the master plate 101 is widened, and these are two drive fingers 126 fixed on the periphery of this notch 125 which engage the tool 124 in the groove 127. As will be readily understood, the advantage of these other modes of guidance is that the parts which can wear during operation can be replaced.

Dans ce mode de réalisation, la plaque secondaire 325 est reliée à la plaque maîtresse 101 par une broche 131 et une vis qui sont horizontaux et parallèles entre eux.In this embodiment, the secondary plate 325 is connected to the master plate 101 by a pin 131 and a screw which are horizontal and parallel to each other.

Tel qu'illustré, la broche 131 traverse orthogonalement la plaque secondaire 325 où elle est solidaire par coincement ou soudure, et elle pénètre dans un orifice en correspondance aménagé dans la plaque maîtresse 101 dans laquelle elle peut coulisser. Un agencement inverse peut également être envisagé : c'est à dire une broche 131 solidaire de la plaque maîtresse et une plaque secondaire 325 coulissant alors le long de cette broche.As illustrated, the pin 131 passes orthogonally through the secondary plate 325 where it is secured by wedging or welding, and it enters a corresponding orifice arranged in the master plate 101 in which it can slide. A reverse arrangement can also be envisaged: that is to say a spindle 131 secured to the master plate and a secondary plate 325 then sliding along this spindle.

La vis, dont la partie fileté 145 est orientée vers la plaque maîtresse 101, traverse la plaque secondaire 325 en sa partie lisse 140. Cette partie lisse 140 est maintenue axialement dans la plaque maîtresse, mais mobile en rotation, par un épaulement ou rondelle 144 du côté de la plaque maîtresse et une tête 141 de l'autre côté. La partie filetée 145 de cette vis est engagée dans un orifice taraudé en correspondance de la plaque maîtresse 101. La tête 141 est par ailleurs complétée sur son pourtour par une poignée 147 et par une série d'orifices semi-sphériques. Proche de cette tête 141 se situe un logement contenant un ressort 143 repoussant hors de ce logement une petite bille 142, laquelle bille pénètre dans l'un des orifices de la tête 141. Ce dispositif d'orifices et de bille permet d'indexer la position angulaire de la vis.The screw, the threaded part 145 of which is oriented towards the master plate 101, passes through the secondary plate 325 in its smooth part 140. This smooth part 140 is held axially in the master plate, but movable in rotation, by a shoulder or washer 144 on the side of the master plate and a head 141 on the other side. The threaded part 145 of this screw is engaged in a tapped orifice in correspondence with the master plate 101. The head 141 is also completed on its periphery by a handle 147 and by a series of semi-spherical orifices. Close to this head 141 is a housing containing a spring 143 pushing out of this housing a small ball 142, which ball enters one of the orifices of the head 141. This device of orifices and ball makes it possible to index the angular position of the screw.

Il apparaît alors de manière évidente que, par action sur la poignée 147, on peut tourner la vis qui, par contre-réaction de la partie fileté 145 dans son orifice taraudé, se déplace vers la droite ou la gauche selon le sens de rotation imprimé en emmenant avec elle la plaque secondaire 325 du fait de la présence de l'épaulement 144 et de la tête 141. Aucun coincement n'est possible compte tenu du diamètre supérieur de la broche 131 et de la surépaisseur de la plaque secondaire à ce niveau. On peut aussi prévoir une rampe hélicoïdale à la place de la partie filetée 145 et un aménagement en conséquence de l'orifice pour améliorer la continuité du mouvement de translation.It then becomes obvious that, by action on the handle 147, the screw can be turned which, by feedback from the threaded part 145 in its tapped hole, moves to the right or the left according to the direction of rotation printed by taking with it the secondary plate 325 due to the presence of the shoulder 144 and the head 141. No jamming is possible given the larger diameter of the spindle 131 and the excess thickness of the secondary plate at this level . One can also provide a helical ramp in place of the threaded portion 145 and a corresponding arrangement of the orifice to improve the continuity of the translational movement.

Bien évidemment, on peut également envisager une disposition inverse pour la vis dans laquelle la partie lisse 140 est prise dans la plaque maîtresse (101) avec la partie fileté 145 agissant dans un orifice taraudé de la plaque secondaire 325. Le principe de fonctionnement reste alors identique.Obviously, one can also envisage a reverse arrangement for the screw in which the smooth part 140 is taken in the master plate (101) with the threaded part 145 acting in a tapped orifice of the secondary plate 325. The operating principle then remains identical.

Selon une autre variante, la broche 131 est remplacée par une seconde vis dont la partie filetée pénètre dans un second orifice taraudé en correspondance dans la plaque maîtresse, et dont la tête est tenue longitudinalement de facon mobile en rotation par la plaque secondaire. Un dispositif de déplacement autorise l'entraînement de la vis par la première.According to another variant, the spindle 131 is replaced by a second screw, the threaded part of which enters a second orifice tapped in correspondence in the master plate, and the head of which is held longitudinally in a manner movable in rotation by the secondary plate. A displacement device allows the screw to be driven by the first.

Tel qu'illustré sur les figures 1 et 3, les moyens de guidage de l'outil refouleur 60 par la plaque secondaire se présente sous la forme d'une fourche en arc-de-cercle engageant directement la rainure 70 de l'outil. De manière évidente, ce moyen n'est nullement limitatif et on peut facilement adapter sur cette plaque secondaire 325 les autres moyens de guidage précédemment décrits.As illustrated in FIGS. 1 and 3, the means for guiding the delivery tool 60 by the secondary plate is in the form of a semi-circular fork directly engaging the groove 70 of the tool. Obviously, this means is in no way limiting and it is easy to adapt the other guide means previously described on this secondary plate 325.

N'alourdissant guère les dispositifs mêmes de réglages initiaux de position latérale, ce dispositif de décalage selon l'invention réduit sensiblement le temps d'immobilisation de la machine lors d'un passage de la production d'un type de boîte à un autre. Selon le nombre d'orifices de blocage 211 présents sur le dessus du support 205 ou sur le pourtour de la tête de vis 141, l'opérateur peut régler ce décalage à 1/8ème, 1/4 ou la moitié de la largeur de la refente.Barely weighing down the very devices for initial lateral position adjustments, this shift device according to the invention significantly reduces the downtime of the machine during a transition from production from one type of box to another. Depending on the number of locking holes 211 present on the top of the support 205 or on the periphery of the screw head 141, the operator can adjust this offset to 1 / 8th, 1/4 or half the width of the split.

De nombreuses autres améliorations peuvent être apportées à ce dispositif dans le cadre de cette invention.Many other improvements can be made to this device in the context of this invention.
