Description

La présente invention concerne une plieuse pour découper et plier une bande de papier, la plieuse étant du type comprenant :

  • un dispositif de découpe de feuilles dans la bande,
  • un cylindre de pliage muni de dispositifs mobiles de maintien et de lames mobiles de pliage des feuilles découpées dans la bande, ledit cylindre étant mobile en rotation autour de son axe,
  • une came de commande du déplacement des dispositifs mobiles de maintien par contact avec des suiveurs de came,
  • une came de commande du déplacement des lames engageantes par contact avec des suiveurs de came, et
  • au moins une came masque présentant une configuration de fonctionnement en accumulation, dans laquelle la came masque neutralise des zones au moins une des cames de commande, et une configuration de fonctionnement en double production dans laquelle la came masque n'interfère pas avec lesdites zones.
The present invention relates to a folder for cutting and folding a strip of paper, the folder being of the type comprising:
  • a sheet cutting device in the strip,
  • a folding cylinder provided with movable holding devices and movable blades for folding sheets cut in the strip, said cylinder being able to rotate about its axis,
  • a cam for controlling the displacement of the movable holding devices by contact with cam followers,
  • a control cam for moving the engaging blades by contact with cam followers, and
  • at least one mask cam having an accumulation operating configuration, wherein the mask cam neutralizes zones at least one of the control cams, and a dual-mode operating configuration in which the mask cam does not interfere with said zones.

L'invention s'applique en particulier au pliage de bandes de papier imprimées par des presses offset.The invention applies in particular to the folding of paper strips printed by offset presses.

On connaît deux catégories principales de plieuse du type précité, à savoir les plieuses à mâchoires (« jaw folder » en anglais) et les plieuses à la volée (« rotary folder » en anglais). Dans ces deux catégories de plieuses, les dispositifs de maintien sont constitués par des picots qui viennent s'engager dans les bords des feuilles découpées.There are two main categories of folding machine of the aforementioned type, namely the jaw folders ("jaw folder" in English) and the folders on the fly ("rotary folder" in English). In these two categories of folders, the holding devices consist of pins that engage in the edges of the cut sheets.

Dans les plieuses à mâchoires, le cylindre de pliage coopère avec un cylindre à mâchoires afin d'assurer le pliage des feuilles. Plus précisément, les feuilles sont poussées par les lames engageantes (« tucking blades » en anglais) entre les mâchoires du cylindre à mâchoires afin d'y assurer le pliage des feuilles. Dans les plieuses à la volée, le cylindre à mâchoires est remplacé par deux rouleaux cannelés.In jaw folders, the folding cylinder cooperates with a jaw cylinder to ensure the folding of the sheets. Specifically, the leaves are pushed by the engaging blades ("tucking blades" in English) between the jaws of the jaw cylinder to ensure the folding of the leaves. In the bending machines on the fly, the jaw cylinder is replaced by two fluted rollers.

Ces plieuses peuvent fonctionner en mode double production (« straight » en anglais) et en mode accumulation (« collect » en anglais). En mode double production chaque feuille est découpée, maintenue sur le cylindre de pliage puis pliée individuellement par coopération d'une lame engageante soit avec le cylindre à mâchoires, soit avec les rouleaux cannelés, en fonction de la catégorie de la plieuse. Les picots maintenant la feuille sont simultanément dégagés de la feuille pour permettre à la feuille pliée d'être évacuée sous forme d'un cahier. Le déplacement des picots et des lames engageantes est assuré via les cames de commande sur lesquelles des suiveurs de came, sous forme de galets reliés aux lames engageantes et aux picots, roulent.These folders can operate in dual production mode ("straight" in English) and accumulation mode ("collect" in English). In double production mode each sheet is cut, held on the folding cylinder and then individually folded by cooperation of an engaging blade with either the jaw cylinder or the fluted rollers, depending on the category of the folder. The pimples holding the leaf are simultaneously released from the sheet to allow the folded sheet to be evacuated in the form of a notebook. Displacement of the pins and engaging blades is provided via the control cams on which cam followers, in the form of rollers connected to the engaging blades and pins, roll.

Ces cames de commande présentent par exemple des creux dans lesquels chaque galet peut pénétrer pour provoquer le retrait des picots correspondants, et ainsi libérer la feuille, ou pour provoquer la saillie de la lame engageante correspondante, pour produire un pli dans la feuille.These control cams for example have recesses in which each roller can penetrate to cause the withdrawal of the corresponding pins, and thus release the sheet, or to cause the projection of the corresponding engaging blade, to produce a fold in the sheet.

Dans le mode accumulation, une première feuille découpée est maintenue sur le cylindre de pliage pour être recouverte par une deuxième feuille découpée. Le mode accumulation permet donc de produire des cahiers comportant un nombre de pages plus important.In the accumulation mode, a first cut sheet is held on the folding cylinder to be covered by a second cut sheet. The accumulation mode therefore makes it possible to produce notebooks with a larger number of pages.

Afin d'éviter le retrait des picots maintenant la première feuille et la saillie de la lame engageante correspondante, deux cames masques sont disposées latéralement à côté des cames de commande des picots et des lames engageantes. Ces cames masques présentent des saillies au droit des creux des cames de commande. Les arbres portant les galets destinés à rouler sur les cames de commande portent également d'autres galets destinés à rouler sur les cames masques.In order to avoid the removal of the pins holding the first sheet and the protrusion of the corresponding engaging blade, two mask cams are arranged laterally adjacent to the control cams of the pins and the engaging blades. These cams masks have projections to the right of the recesses of the control cams. The shafts carrying the rollers for rolling on the control cams also carry other rollers for rolling on the masking cams.

Ainsi, ces autres galets roulent sur les saillies des cames masques et empêchent les galets associés aux cames de commande de pénétrer dans les creux correspondants.Thus, these other rollers roll over the protrusions of the masking cams and prevent the rollers associated with the control cams from entering the corresponding recesses.

Les cames masques neutralisent donc des zones des cames de commande et évitent, de manière contrôlée, le déplacement des picots et des lames engageantes.The mask cams thus neutralize zones of the control cams and avoid, in a controlled manner, the movement of the pins and the engaging blades.

En mode accumulation, les cames masques tournent autour de l'axe du cylindre de pliage à une vitesse généralement égale à 2,5 fois celle du cylindre de pliage, lorsque le cylindre de pliage est équipé de cinq dispositifs de maintien et de cinq lames engageantes. Lorsque le cylindre de pliage comprend trois dispositifs de maintien et trois lames engageantes, la vitesse de la came masque est égale à 1,5 fois celle du cylindre de pliage.In accumulation mode, the mask cams rotate around the axis of the folding cylinder at a speed generally equal to 2.5 times that of the folding cylinder, when the folding cylinder is equipped with five holding devices and five engaging blades. . When the folding cylinder comprises three holding devices and three engaging blades, the speed of the mask cam is 1.5 times that of the folding cylinder.

Pour passer du mode accumulation au mode double production, les cames masques doivent être débrayées et immobilisées dans une position angulaire dans laquelle elles n'interfèrent pas avec les cames de commande. Les opérations inverses sont nécessaires pour repasser en mode accumulation.To switch from accumulation mode to dual production mode, the mask cams must be disengaged and locked in one position angular in which they do not interfere with the control cams. Reverse operations are required to return to accumulation mode.

Le changement de mode nécessite donc des positionnements angulaires précis, notamment pour immobiliser la ou les cames masques, et pour assurer leur réembrayage. Ceci est contraignant et limite en outre fortement les possibilités d'automatisation du changement de mode de pliage.The change of mode therefore requires precise angular positioning, in particular to immobilize the cams or masks, and to ensure their re-engagement. This is restrictive and also strongly limits the automation possibilities of the folding mode change.

Un but de l'invention est de résoudre ce problème en fournissant une plieuse du type précité qui permette de passer plus simplement du mode accumulation au mode double production.An object of the invention is to solve this problem by providing a bender of the aforementioned type that allows to simply switch from accumulation mode to dual production mode.

A cet effet, l'invention a pour objet une plieuse du type précité, caractérisée en ce que la came masque comprend deux demi-cames, sensiblement symétrique l'une de l'autre par rapport à l'axe du cylindre, mobiles radialement chacune entre une position escamotée et une position extraite, la came masque étant en configuration de fonctionnement en double production lorsque les demi-cames sont en position escamotée et en configuration de fonctionnement en accumulation lorsque les demi-cames sont en position extraite.For this purpose, the object of the invention is a folding machine of the aforementioned type, characterized in that the mask cam comprises two half-cams, substantially symmetrical to each other with respect to the axis of the cylinder, radially movable each between a retracted position and an extracted position, the mask cam being in dual-operation configuration when the half-cams are in the retracted position and in accumulated operating configuration when the half-cams are in the retracted position.

Dans l'exemple décrit, la plieuse est une plieuse 3/2 et comprend donc trois séries de picots 6, 7 et 8 et trois lames engageantes 9, 10 et 11.In the example described, the folder is a 3/2 folder and therefore comprises three series of pins 6, 7 and 8 and three engaging blades 9, 10 and 11.

Les séries 6, 7 et 8 de picots et les lames engageantes 9, 10 et 11 sont montées mobiles sur le cylindre de pliage 3 sous l'action de galets qui viennent rouler sur des cames de commande non représentées. Plus généralement, ces galets peuvent être dénommés suiveurs de came. Ces galets sont portés par le cylindre de pliage 3 et entraînés en rotation par ce dernier.Series 6, 7 and 8 of pins and engaging blades 9, 10 and 11 are movably mounted on the folding cylinder 3 under the action of rollers which are rolled on unrepresented control cams. More generally, these rollers may be called cam followers. These rollers are carried by the folding cylinder 3 and rotated by the latter.

Dans le mode de fonctionnement en double production, illustré par la figure 1, une feuille 12 a été découpée de la bande 2 par le cylindre 4 et y a été maintenue par la série de picots 8.In the dual production mode of operation, illustrated in FIG. 1, a sheet 12 has been cut from the strip 2 by the cylinder 4 and has been held there by the series of pins 8.

Comme illustré par la partie A de la figure 1, lorsque la lame engageante 11 se trouve en regard des rouleaux 5, le galet correspondant s'enfonce dans un creux de la came de commande correspondante, ce qui provoque la saillie de la lame 11 qui vient s'engager entre les rouleaux 5 en y poussant la feuille 12. La lame 11 forme alors un pli dans la feuille 12.As illustrated by the part A of FIG. 1, when the engaging blade 11 is facing the rollers 5, the corresponding roller goes into a recess of the corresponding control cam, which causes the protrusion of the blade 11 which is engaged between the rollers 5 by pushing the sheet 12. The blade 11 then forms a fold in the sheet 12.

Simultanément, le galet associé à la série de picots 8 a pénétré dans un creux de la came de commande correspondante, provoquant la rétraction de la série de picots 8 ce qui permet aux rouleaux 5 d'évacuer la feuille 12. La feuille 12 est alors munie d'un pli transversal par rapport au sens de défilement et forme un cahier comprenant une seule feuille.Simultaneously, the roller associated with the series of pins 8 has penetrated into a recess of the corresponding control cam, causing the retraction of the series of pins 8 which allows the rollers 5 to evacuate the sheet 12. The sheet 12 is then provided with a fold transverse to the direction of scrolling and forms a notebook comprising a single sheet.

Les parties B à D de la figure 1 illustrent comment la plieuse 1 va continuer à découper et à plier ultérieurement des feuilles 13, 14 et 15 depuis la bande 2, le cylindre de pliage 3 continuant à tourner dans le sens des aiguilles d'une montre sur la figure 1.Parts B to D in FIG. 1 illustrate how the folder 1 will continue to cut and subsequently fold sheets 13, 14 and 15 from the strip 2, the folding roll 3 continuing to rotate in a clockwise fashion. shows in Figure 1.

La figure 2 illustre le mode de pliage en accumulation avec à nouveau des parties A à D représentant des étapes successives.Figure 2 illustrates the accumulation folding mode with again portions A to D representing successive steps.

Contrairement à ce qui se passe en mode de pliage en double production, et comme illustré par la partie A, une feuille 16 découpée de la bande 2 est maintenue sur le cylindre de pliage 3 et n'est pas pliée lorsqu'elle passe en regard des rouleaux 5. Cela est assuré en neutralisant provisoirement les reliefs correspondants des cames de commande des séries de picots et des lames engageantes, grâce à une ou plusieurs cames masques.Contrary to what happens in double production folding mode, and as illustrated by part A, a sheet 16 cut from the strip 2 is held on the folding cylinder 3 and is not folded as it passes by 5. This is ensured by temporarily neutralizing the reliefs corresponding control cams series of pins and engaging blades, through one or more cams masks.

On observera que le cylindre de pliage 3 porte par ailleurs une autre feuille 17 qui a été préalablement découpée dans la bande 2 et qui est maintenue sur le cylindre 3 par la série de picots 6.It will be observed that the folding cylinder 3 also carries another sheet 17 which has been previously cut in the strip 2 and which is held on the cylinder 3 by the series of pins 6.

Dans la partie B de la figure 2, une feuille 18 est découpée et enroulée sur la feuille 17 puis, lorsque la lame engageante 9 se trouve en regard des rouleaux 5, celle-ci et la série de picots 6 sont actionnés afin de libérer les feuilles 17 et 18 et de les pousser entre les rouleaux 5 pour y former un cahier de deux feuilles munies d'un pli transversal.In Part B of Figure 2, a sheet 18 is cut and wound on the sheet 17 and, when the engaging blade 9 is facing the rollers 5, the latter and the series of pins 6 are actuated to release the leaves 17 and 18 and push them between the rollers 5 to form a notebook of two sheets provided with a transverse fold.

Pour ce faire, les reliefs correspondants des cames de commande n'ont pas été neutralisés par la ou les cames masques.To do this, the corresponding reliefs of the control cams have not been neutralized by the masking cam or cams.

Les parties C et D de la figure 2 illustrent la découpe ultérieure de deux autres feuilles 19 et 20. Le mode de pliage en accumulation permet donc de produire des cahiers avec un nombre de pages plus important.Parts C and D of FIG. 2 illustrate the subsequent cutting of two other sheets 19 and 20. The accumulation folding mode therefore makes it possible to produce notebooks with a larger number of pages.

Les figures 3 à 7 illustrent une plieuse selon l'invention.Figures 3 to 7 illustrate a folder according to the invention.

La figure 3 illustre schématiquement une extrémité 21 du cylindre de pliage 3 qui est reçu via un palier 22 dans une des parois latérales 24 du bâti de la plieuse 3. La paroi 24 représentée est par exemple celle située du côté service.3 schematically illustrates an end 21 of the folding cylinder 3 which is received via a bearing 22 in one of the side walls 24 of the frame of the folder 3. The wall 24 shown is for example that located on the service side.

L'autre paroi latérale du bâti, située du côté transmission, est munie de moyens permettant d'assurer un entraînement en rotation des cylindres et rouleaux de la plieuse, et notamment du cylindre de pliage 3 autour de son axe A.The other side wall of the frame, located on the transmission side, is provided with means for ensuring a rotational drive of the rolls and rolls of the folder, and in particular of the folding roll 3 about its axis A.

On distingue sur la figure 3 la came 26 de commande des séries de picots 6 à 8, cette came 26 est disposée autour de l'extrémité 21 du cylindre 3 et est fixée sur la paroi 24.FIG. 3 shows the control cam 26 of the series of pins 6 to 8, this cam 26 is disposed around the end 21 of the cylinder 3 and is fixed on the wall 24.

Latéralement plus proche de la paroi 24, on peut également distinguer la came 28 de commande des lames engageantes 9 à 11, cette came 28 est également fixée sur la paroi latérale 24. On distingue également un des suiveurs de came 30 ou galets destinés à coopérer avec la came 28 et à actionner les lames engageantes 9 à 11. Sur l'arbre 32, qui porte le suiveur de la came 30, est également monté un autre suiveur de came 34 destiné à coopérer avec la came masque 36. Cette came masque 36 est intercalée latéralement entre les deux cames de commande 26 et 28.Laterally closer to the wall 24, one can also distinguish the control cam 28 of the engaging blades 9 to 11, this cam 28 is also attached to the side wall 24. There is also a cam follower 30 or roller for cooperating with the cam 28 and to actuate the engaging blades 9 to 11. On the shaft 32, which carries the follower of the cam 30, is also mounted another cam follower 34 intended to cooperate with the cam mask 36. This mask cam 36 is inserted laterally between the two control cams 26 and 28.

On observera que les suiveurs de came 30 et 34 symétriques de ceux représentés n'ont pas été représentés sur la partie supérieure de la figure 3.It will be observed that the cam followers 30 and 34 symmetrical of those shown have not been represented on the upper part of FIG. 3.

Sur la figure 3, on distingue un creux 37 de la came de commande 28 dans lequel le suiveur de came 30 ne peut pas pénétrer du fait de l'appui du suiveur de came 34 sur la came masque 36. C'est typiquement le phénomène qui se produit lors du fonctionnement en accumulation comme décrit ultérieurement.In FIG. 3, there is a hollow 37 of the control cam 28 in which the cam follower 30 can not penetrate because of the support of the cam follower 34 on the mask cam 36. This is typically the phenomenon which occurs during accumulation operation as described later.

De même, chaque autre suiveur de came de la came de commande 26 et chaque suiveur de came de la came de commande 28 sont associés à un autre suiveur de came destiné à coopérer avec la came masque 36. Toutefois, ces derniers suiveurs de came sont situés dans des plans différents de la figure 3 et ne sont donc pas visibles sur cette figure.Likewise, each other cam follower of the control cam 26 and each cam follower of the control cam 28 are associated with another cam follower intended to cooperate with the mask cam 36. However, these latter cam followers are located in different planes of Figure 3 and are not visible in this figure.

Tous les suiveurs de came sont portés par le cylindre de pliage 3 et l'accompagnent donc dans ses rotations autour de son axe A.All cam followers are carried by the folding cylinder 3 and thus accompany it in its rotations about its axis A.

Comme illustré par les figures 3 à 5, la came masque 36 comprend principalement :

  • un moyeu central 38,
  • deux demi-cames 40,
  • deux ressorts à gaz 42 de rappel des demi-cames 40 radialement vers l'extérieur, et
  • deux mécanismes à genouillère 44.
As illustrated by FIGS. 3 to 5, the mask cam 36 mainly comprises:
  • a central hub 38,
  • two half-cams 40,
  • two gas springs 42 for returning the half-cams 40 radially outwards, and
  • two toggle mechanisms 44.

La came masque 36 a une forme et un agencement de ses éléments sensiblement symétriques par rapport à l'axe A.The mask cam 36 has a shape and an arrangement of its elements substantially symmetrical with respect to the axis A.

Son moyeu 38 est disposé autour de l'extrémité 21 du cylindre 3 et, grâce à des roulements 46, peut pivoter librement par rapport à celle-ci.Its hub 38 is arranged around the end 21 of the cylinder 3 and, thanks to the bearings 46, can rotate freely relative thereto.

Un train d'engrenages 48 est porté par la paroi 24 pour entraîner la came masque 36 en rotation autour de l'axe A, à partir de l'extrémité 21 du cylindre 3, à une vitesse de rotation qui vaut par exemple 1,25 fois celle du cylindre 3, si le cylindre 3 est équipé de cinq lames engageantes et de cinq dispositifs de maintien. Si le cylindre de pliage 3 est équipé de trois lames engageantes et de trois dispositifs de maintien, la vitesse de la came masque 36 vaut 0,75 fois celle du cylindre de pliage 3.A gear train 48 is carried by the wall 24 to drive the mask cam 36 in rotation about the axis A, from the end 21 of the cylinder 3, at a rotational speed which is, for example, 1.25 the cylinder 3, if the cylinder 3 is equipped with five engaging blades and five holding devices. If the folding cylinder 3 is equipped with three engaging blades and three holding devices, the speed of the mask cam 36 is 0.75 times that of the folding cylinder 3.

Du fait de la symétrie de la came masque 36, seule une demi-came 40 sera décrite par la suite.Due to the symmetry of the mask cam 36, only one half-cam 40 will be described later.

La demi-came 40 a une forme générale en arc de cercle et présente une surface radialement extérieure 50 destinée à venir au contact des suiveurs de came 34.The half cam 40 has a generally circular shape and has a radially outer surface 50 intended to come into contact with the cam followers 34.

Une première extrémité 52 de la demi-came 40 est articulée sur le moyeu 38 en un point 53. L'autre extrémité 54 de la demi-came 40 est reliée à l'extrémité 52 de l'autre demi-came 40 par un ressort 42 et au moyeu 48 par un mécanisme à genouillère 44.A first end 52 of the half-cam 40 is articulated on the hub 38 at a point 53. The other end 54 of the half-cam 40 is connected to the end 52 of the other cam half 40 by a spring 42 and the hub 48 by a toggle mechanism 44.

La demi-came 40 est mobile radialement par pivotement par rapport au moyeu 38 entre deux positions.The half-cam 40 is movable radially by pivoting relative to the hub 38 between two positions.

Une première position est illustrée par la figure 4. Il s'agit d'une position extraite. Dans cette position, la surface 50 est située radialement à l'extérieur comme illustré par le cercle extérieur C2 en traits mixtes.A first position is illustrated in Figure 4. This is an extracted position. In this position, the surface 50 is located radially on the outside as illustrated by the outer circle C2 in phantom.

Lorsque les deux demi-cames sont dans cette position, les deux ressorts 42 sont en positions détendues et les mécanismes à genouillère 44 sont en positions désalignées et les extrémités 54 des demi-cames sont plus éloignées de l'axe A. La plieuse 1 peut alors fonctionner en mode accumulation comme cela sera décrit par la suite.When the two half-cams are in this position, the two springs 42 are in relaxed positions and the toggle mechanisms 44 are in misaligned positions and the ends 54 of the half-cams are farther from the axis A. The folder 1 can then operate in accumulation mode as will be described later.

La figure 5 illustre la deuxième position, c'est-à-dire la position escamotée. Dans cette position, la surface 50 est située radialement plus à l'intérieur comme matérialisé par le cercle intérieur C2. Les ressorts 42 sont alors en positions comprimées et les extrémités 54 correspondantes des demi-cames 40 sont donc plus proches de l'axe A. Les mécanismes à genouillère 44 sont encore en positions désalignées mais dans des positions autres que celles qu'elles occupent sur la figure 4. Les mécanismes à genouillère 44 sont alors en positions de fin de course.Figure 5 illustrates the second position, that is, the retracted position. In this position, the surface 50 is located radially further inward as materialized by the inner circle C2. The springs 42 are then in compressed positions and the corresponding ends 54 of the half-cams 40 are therefore closer to the axis A. The toggle mechanisms 44 are still in misaligned positions but in positions other than those they occupy on Figure 4. The toggle mechanisms 44 are then in end positions.

La figure 5 correspond à un mode de fonctionnement de la plieuse 1 en double production.Figure 5 corresponds to a mode of operation of the bender 1 in double production.

Lors du passage de la configuration de la figure 4 à la configuration de la figure 5, les mécanismes à genouillère 44 passent par des positions alignées, dans lesquelles leurs articulations intermédiaires 56 et leurs articulations 58 de liaison aux demi-cames 40 et au moyeu 38 sont alignées.During the transition from the configuration of FIG. 4 to the configuration of FIG. 5, the toggle mechanisms 44 pass through aligned positions, in which their intermediate hinges 56 and their hinges 58 connect to the half-cams 40 and to the hub 38 are aligned.

Ainsi, les configurations illustrées sur les figures 4 et 5 sont des configurations stables.Thus, the configurations illustrated in Figures 4 and 5 are stable configurations.

Les figures 6 et 7 illustrent le système de commande de changement de configuration de la came masque 36. Le sens de rotation de la came masque 36 y est schématisé par la flèche F. Ce système 60 comprend un aiguillage 62 qui peut être actionné via un vérin 64 et éventuellement un bras 66. Le vérin 64 est un vérin pneumatique à double effet.FIGS. 6 and 7 illustrate the configuration change control system of the mask cam 36. The direction of rotation of the mask cam 36 is shown schematically by the arrow F. This system 60 comprises a switch 62 which can be actuated via a jack 64 and possibly an arm 66. The jack 64 is a pneumatic cylinder with double effect.

L'aiguillage 62 est par exemple constitué par un rail délimité par deux bords latéraux 67 et qui converge d'une entrée 68 large vers une sortie 70 étroite.The switch 62 is for example constituted by a rail delimited by two lateral edges 67 and which converges from a wide inlet 68 to a narrow outlet 70.

L'aiguillage 62 peut pivoter en un point 71 par rapport à la paroi 24 entre une première position (figure 6), dans laquelle la sortie 70 est rapprochée de l'axe A, et une deuxième position (figure 7), dans laquelle la sortie 70 est écartée de l'axe A.The switch 62 can pivot at a point 71 with respect to the wall 24 between a first position (FIG. 6), in which the outlet 70 is close to the axis A, and a second position (FIG. 7), in which the output 70 is spaced from the axis A.

L'aiguillage 62 est destiné à coopérer, comme cela sera décrit par la suite avec des organes, par exemple des galets 72, portés par les articulations intermédiaires 56 des mécanismes à genouillère 44.The switch 62 is intended to cooperate, as will be described later with members, for example rollers 72, carried by the intermediate hinges 56 of the toggle mechanisms 44.

En mode double production, la came masque 36 est dans la configuration illustrée par la figure 5 et l'aiguillage 62 dans la position illustrée par la figure 6.In dual production mode, the mask cam 36 is in the configuration shown in FIG. 5 and the switch 62 in the position illustrated in FIG.

Les surfaces extérieures 50 des demi-cames 40 sont donc radialement en retrait et ne viennent pas interférer avec les reliefs des cames de commande 26 et 28. En d'autres termes, les suiveurs 34 de la came masque 36 ne viennent pas au contact de cette dernière et les déplacements des séries de picots 6 à 8 et des lames engageantes 9 à 11 sont uniquement commandés par les suiveurs de came associés aux cames 26 et 28 qui viennent rouler sur ces dernières.The outer surfaces 50 of the half-cams 40 are therefore radially recessed and do not interfere with the reliefs of the control cams 26 and 28. In other words, the followers 34 of the mask cam 36 do not come into contact with each other. the latter and the movements of the series of pins 6 to 8 and the engaging blades 9 to 11 are only controlled by the cam followers associated with the cams 26 and 28 which roll over them.

Lors de la rotation de la came masque 36 autour de l'axe A, les deux galets 72 portés par les articulations intermédiaires 56 des mécanismes 44 passent dans l'aiguillage 62 sans venir au contact de ses bords latéraux 67. La trajectoire des galets 72 est alors illustrée par le cercle C3.During the rotation of the mask cam 36 about the axis A, the two rollers 72 carried by the intermediate joints 56 of the mechanisms 44 pass through the switch 62 without coming into contact with its lateral edges 67. The path of the rollers 72 is then illustrated by the circle C3.

Lorsque l'on souhaite passer en mode accumulation, le vérin 64 provoque le passage de l'aiguillage 62 dans la position écartée de la figure 7. Le premier galet 72 à pénétrer, du fait de la rotation de la came 36, dans l'aiguillage 62 entre progressivement au contact du bord 67 intérieur, qui provoque l'écartement radial progressif du galet 72 jusqu'à la trajectoire matérialisée par le cercle C4. Le mécanisme à genouillère 44 correspondant passe, sous l'action combinée des ressorts 42 qui repoussent les demi-cames 40 vers leurs positions de la figure 4, en position alignée puis dans la position désalignée de la figure 4. La came masque 36 est alors dans la configuration de la figure 4. Les bords radialement extérieurs 50 des demi-cames 40 sont alors situés radialement plus à l'extérieur que les fonds des creux de la came de commande 26 et des creux 37 de la came de commande 28.When it is desired to go into accumulation mode, the jack 64 causes the switch 62 to move to the position removed from FIG. 7. The first roller 72 to enter, due to the rotation of the cam 36, into the referral 62 between progressively in contact with the inner edge 67, which causes the progressive radial spacing of the roller 72 to the path materialized by the circle C4. The corresponding toggle mechanism 44 passes, under the combined action of the springs 42 which push the half-cams 40 to their positions of Figure 4, in the aligned position and then in the misaligned position of Figure 4. The cam mask 36 is then in the configuration of FIG. 4. The radially outer edges 50 of the half-cams 40 are then located radially more outward than the bottoms of the recesses of the control cam 26 and the recesses 37 of the control cam 28.

Ainsi, les suiveurs de came 34 venant rouler sur les surfaces extérieures 50 vont empêcher les suiveurs des cames de commande 26 et 28 de pénétrer dans ces creux.Thus, the cam followers 34 rolling on the outer surfaces 50 will prevent the followers of the cams 26 and 28 from entering these recesses.

La came masque 36 interfère donc avec les cames de commande 26 et 28 pour pouvoir atteindre le fonctionnement en accumulation décrit par référence à la figure 2.The mask cam 36 therefore interferes with the control cams 26 and 28 in order to reach the accumulation operation described with reference to FIG. 2.

Le passage du mode en accumulation en mode en double production s'effectue par déplacement radial de parties de la came masque 36. Tous les problèmes liés au désembrayage/réembrayage et au positionnement angulaire de l'état de la technique sont donc supprimés.The transition from the accumulation mode to the dual production mode is effected by radial displacement of parts of the mask cam 36. All the problems related to the declutching / re-clutching and the angular positioning of the state of the art are thus eliminated.

Ainsi, le passage d'un mode de fonctionnement à l'autre est fiable, rapide et peut être entièrement automatisé comme décrit précédemment.Thus, the transition from one mode of operation to another is reliable, fast and can be fully automated as described above.

De manière générale, la came 36 a donc un fonctionnement simple et fiable et s'avère économique.In general, the cam 36 therefore has a simple and reliable operation and is economical.

On observera en outre qu'il n'est pas nécessaire de prévoir un dispositif d'immobilisation de la came masque 36 en mode double production, ce qui simplifie encore la structure et élimine les problèmes associés à ces dispositifs d'immobilisation.It will further be observed that it is not necessary to provide a device for immobilizing the mask cam 36 in dual production mode, which further simplifies the structure and eliminates the problems associated with these immobilizing devices.

De plus, dans le mode double production, les galets 34 ne viennent pas en contact de la came masque 36, ce qui limite donc l'usure de ces différents éléments.In addition, in the dual production mode, the rollers 34 do not come into contact with the mask cam 36, which therefore limits the wear of these different elements.

Par ailleurs, la came masque 36 forme un ensemble bistable mécaniquement, elle n'est pas susceptible d'être affectée par une coupure de courant ou une perte totale de pression dans le circuit d'alimentation.Furthermore, the mask cam 36 forms a mechanically bistable assembly, it is not likely to be affected by a power failure or a total loss of pressure in the supply circuit.

On observera de plus que l'utilisation de deux demi-cames 36 destinées à agir chacune avec les suiveurs de came 30 permet de réduire par deux sa vitesse en rotation par rapport à une came présentant un seul secteur deux fois plus long.It will further be observed that the use of two half-cams 36 intended to act each with the cam followers 30 makes it possible to reduce by two its speed in rotation with respect to a cam having a single sector twice as long.

L'énergie cinétique liée à la rotation de la came 36 est donc divisée par quatre, ce qui s'avère particulièrement intéressant pour les plieuses à grande vitesse de production.The kinetic energy associated with the rotation of the cam 36 is thus divided by four, which proves particularly interesting for high speed production bending machines.

Dans l'exemple décrit ci-dessus, une même came masque est utilisée à la fois pour interférer avec les cames de commande 26 et 28, ce qui permet d'économiser une came par rapport aux plieuses qui en utilisaient auparavant deux.In the example described above, the same mask cam is used both to interfere with the control cams 26 and 28, which saves a cam compared to the benders that previously used two.

Toutefois, dans certains modes d'utilisation, on peut envisager d'utiliser deux cames masques, chacune étant associée avec une came de commande.However, in some modes of use, it is possible to envisage using two mask cams, each being associated with a control cam.

De même, la came masque 36 peut avoir une autre structure, par exemple avec une seule partie active, et dont le déplacement radial n'est pas nécessairement assuré via un mécanisme à genouillère.Similarly, the mask cam 36 may have another structure, for example with only one active part, and whose radial displacement is not necessarily provided via a toggle mechanism.

Le vérin 64 est de préférence muni de bloqueurs de ses chambres d'échappement afin de s'affranchir d'éventuelles coupures d'air intempestives en cours de production.The jack 64 is preferably provided with blockers of its exhaust chambers in order to overcome any unwanted air interruptions during production.

Le vérin 64 peut être plus généralement remplacé par tout autre dispositif d'actionnement et peut être muni de capteurs de détection de sa position.The jack 64 may be more generally replaced by any other actuating device and may be provided with sensors for detecting its position.

Comme indiqué précédemment, l'invention peut également être appliquée à une plieuse à mâchoires. Comme illustré par la figure 8, dans une telle plieuse les rouleaux 5 sont remplacés par un cylindre à mâchoires 75.As indicated above, the invention can also be applied to a jaw folder. As illustrated by FIG. 8, in such a folder the rollers 5 are replaced by a jaw cylinder 75.
