Definitions
- the present invention relates to a device for finishing the fold of booklets composed of sheets stacked and folded along a central line.
- Booklets of this kind can be produced by stacking sheets, stapling along a central line and folding along this same central line. Folding is carried out by introducing, using a blade, the bundle of leaves into the slot defined between two opposite rollers which rotate so as to evacuate the folded booklet.
- the booklet has a tendency to reopen, mainly because of the elasticity of the paper fibers. This tendency of the booklet to reopen is troublesome for the subsequent stages such as the trimming and especially the stacking of the booklets for their packaging.
- the booklet is passed between one or more pairs of rollers, in order to compress or crush the fold. In this way, we manage to reduce, but not eliminate, the tendency of the booklet to reopen.
- the present invention provides a device for finishing the fold of booklets which is capable of eliminating practically any tendency of the booklet to reopen.
- This device comprises at least one pair of parallel and opposite rollers defining between them a slot for the passage of a booklet, at least one of said rollers being driven in rotation and the rollers being biased towards each other; according to the invention, the normal on the plane defined by the axes of said pair of rollers is inclined relative to the direction of advancement of the booklets, and a deflection element of the booklet is arranged upstream of said passage slot for forcibly deflecting the path of the booklet in the direction of said passage slot from said direction of advance.
- the forced deflection of the bundle of sheets has the effect of bending it and exerting a tensile force on the paper fibers on the convex side of the curved bundle.
- the pair of rollers is preferably preceded by another pair of parallel and opposite rollers defining between them a slot for passage of a booklet, at least one of said rollers being driven in rotation and the rollers being biased towards each other, the plane defined by the axes of said pair of rollers being normal to the direction of advancement of the booklets.
- the spacing between the pairs of rollers is such that a booklet engaged in the roller passage slot downstream is still engaged in the passage slot of the upstream rollers.
- the upstream rollers oppose the traction, due to the curvature of the bundle, exerted by the downstream rollers on the sheets of paper when the fold is engaged between them.
- the biasing force towards each other of the downstream rollers is preferably significantly greater than that of the upstream rollers when the booklet is engaged in the slot of passage of the downstream rollers.
- common biasing means are provided for the two pairs of rollers, the action of which is selectively applied to one or the other of these.
- These means advantageously consist of two elements for transmitting a bearing force on the axis of one of the rollers of each pair, respectively, the bearing force being applied directly to that of the transmission elements which is associated with the upstream rollers and indirectly, by contact between these transmission elements, to that of the transmission elements which is associated with the downstream rollers.
- the transmission elements consist of pivoting levers having free ends in abutment against one another and intermediate parts bearing on the axis of the associated roller.
- the device for finishing the booklet fold comprises two pairs of rollers 10, 12, mounted in a frame (not shown), in succession along a path for the passage of a bundle 14 of sheets folded along a central line.
- the lower rollers 10b, 12b are each mounted for rotation about a fixed axis and rotated by a motor 16, by means of a belt 18.
- An endless belt 20 is dragged around the rollers 10b, 12b and around a tension roller 22.
- the upper rollers 10a, 12a are mounted with free rotation and vertical displacement; they are biased towards the lower rollers 10b, 12b and in contact with the belt 20 by an associated spring 24, 26, respectively.
- the upper rollers 10a, 12a are rotated indirectly by frictional contact with the belt 20, but their rotation is synchronized by a synchronization belt 28.
- the upper roller 12a is offset from the roller lower 12b towards the first pair 10 of rollers; the normal to the plane defined by the axes of the rollers 12a, 12b is therefore inclined relative to the direction of advance of the bundle 14.
- the belt 20 undergoes a deflection in contact with the roller 12a.
- the folded bundle 14 is deposited on the belt 20 in front of the first pair 10 of rollers, the fold forming the front edge of the bundle.
- the roller 10a is lifted against the force of the spring 24 and pressure is exerted on the fold of the bundle. Then, as can be seen more clearly from FIG.
- the bundle 14 passes into the zone where the belt 20 is deflected by the roller 12a. Pressure is then exerted by the belt 20 on the back of the fold of the bundle 14, as indicated by an arrow in FIG. 2.
- the bundle is deformed along the path of the strap 20, with a convex curvature on the side of the strap and a concave curvature on the side of the roller 12a. By this curvature, the paper fibers are exposed to a tensile force on the side of the belt 20.
- the deflection of the bundle causes shearing forces in the fold area. The combined action of these stresses causes most of the paper fibers to break in the fold area of the bundle 14. As a result, the booklet leaving the device no longer has a tendency to reopen.
- the spacing between the pairs of rollers 10, 12 is preferably small enough so that the bundle 14, when its fold is engaged between the belt 20 and the roller 12a, is still engaged in the passage slot between the belt 20 and the roller 10a.
- the bundle 14 takes a curved shape due to its deflection in contact with the roller 12a, it tends to advance more rapidly on the convex side of the curvature.
- this rear part of the bundle cannot follow the faster advancement of the convex side of the curvature, and the traction exerted on the fibers of the paper is therefore increased. To ensure this effect, it is important that the drive of the rollers 10b and 12b is synchronous.
- the belt 20 is replaced by a guide plate 30.
- the rollers 10a, 10b and 12a, 12b are all coupled as shown schematically in Figure 3, to a drive motor 16, via a transmission chain 32.
- the lower rollers 10b, 12b have their axes adjustable in height in an eccentric support 34 and 36, respectively.
- the rotation of these eccentric supports 34, 36 is controlled manually by a flywheel not shown, to modify the spacing of the rollers as a function of the thickness of the booklets.
- the rollers 10a, 12a are mounted to travel in pivoting arms 38, 40, respectively.
- the biasing of the rollers 10a, 12a towards the rollers 10b, 12b is ensured by a common mechanism whose action is selectively applied to the roller 10a and then to the roller 12a.
- a pivoting lever 42 is supported on the axis of the roller 10a, and a similar pivoting lever 44 is supported on the axis of the roller 12a.
- the free ends of the levers 42, 44 are superimposed and have aligned bores through which a pull rod 46 passes.
- the pull rod 46 carries a pack of spring disks 48 which rests on one side on an element d 'support 50 and, on the other side, on a bolt 52 screwed onto the free end of the pull rod 46.
- the pack of spring disks 48 therefore exerts a pull force on the rod 46, the head of which presses on the free end of the lever 42 which, in turn, pushes on the free end of the lever 44.
- the stressing force of the rollers 10a, 12a depends on the ratio between the length of the lever 42 or 44 and the distance between the pivot point of each lever and its bearing area on the 'axis of the respective roller. This ratio can be varied to obtain different loading forces for the pairs of rollers 10, 12, despite the use of a common mechanism.
- the guide plate 30 forces the bundle on a curved path to break the fibers of the paper in the fold area.

Abstract
Description
La présente invention concerne un dispositif de finition du pli de livrets composés de feuilles empilées et pliées suivant une ligne centrale.The present invention relates to a device for finishing the fold of booklets composed of sheets stacked and folded along a central line.
Des livrets de ce genre peuvent être réalisés par empilage de feuilles, agrafage suivant une ligne centrale et pliage le long de cette même ligne centrale. Le pliage est effectué par introduction, à l'aide d'une lame, de la liasse de feuilles dans la fente définie entre deux rouleaux opposés qui tournent de manière à évacuer le livret plié.Booklets of this kind can be produced by stacking sheets, stapling along a central line and folding along this same central line. Folding is carried out by introducing, using a blade, the bundle of leaves into the slot defined between two opposite rollers which rotate so as to evacuate the folded booklet.
Cependant, à la sortie de ces rouleaux de pliage, le livret a une tendance à se rouvrir, essentiellement à cause de l'élasticité des fibres du papier. Cette tendance du livret à se rouvrir est gênante pour les étapes ultérieures telles que le massicotage et surtout l'empilage des livrets en vue de leur emballage.However, at the exit of these folding rollers, the booklet has a tendency to reopen, mainly because of the elasticity of the paper fibers. This tendency of the booklet to reopen is troublesome for the subsequent stages such as the trimming and especially the stacking of the booklets for their packaging.
Pour remédier à cet inconvénient, on fait passer le livret entre une ou plusieures paires de rouleaux, afin de comprimer ou écraser le pli. De la sorte, on parvient bien à réduire, mais non à éliminer, la tendance du livret à se rouvrir.To remedy this drawback, the booklet is passed between one or more pairs of rollers, in order to compress or crush the fold. In this way, we manage to reduce, but not eliminate, the tendency of the booklet to reopen.
La présente invention propose un dispositif de finition du pli de livrets qui est capable d'éliminer pratiquement toute tendance du livret à se rouvrir.The present invention provides a device for finishing the fold of booklets which is capable of eliminating practically any tendency of the booklet to reopen.
Ce dispositif comporte au moins une paire de rouleaux parallèles et opposés définissant entre eux une fente de passage d'un livret, au moins l'un desdits rouleaux étant entraîné en rotation et les rouleaux étant sollicités l'un vers l'autre; conformément à l'invention, la normale sur le plan défini par les axes de ladite paire de rouleaux est inclinée par rapport à la direction d'avancement des livrets, et un élément de déflexion du livret est agencé en amont de ladite fente de passage pour dévier de manière forcée le trajet du livret en direction de ladite fente de passage à partir de ladite direction d'avancement. La déflexion forcée de la liasse de feuilles a pour effet de la courber et d'exercer un effort de traction sur les fibres de papier du côté convexe de la liasse courbée. En même temps, des efforts de cisaillement sont exercés sur le papier à l'endroit du pli, et la déflexion forcée de la liasse provoque une pression sur le dos du pli au contact avec les rouleaux. Par la conjugaison de ces effets, les fibres de papier sont rompues à l'endroit du pli, et la tendance du pli à se rouvrir est essentiellement éliminée.This device comprises at least one pair of parallel and opposite rollers defining between them a slot for the passage of a booklet, at least one of said rollers being driven in rotation and the rollers being biased towards each other; according to the invention, the normal on the plane defined by the axes of said pair of rollers is inclined relative to the direction of advancement of the booklets, and a deflection element of the booklet is arranged upstream of said passage slot for forcibly deflecting the path of the booklet in the direction of said passage slot from said direction of advance. The forced deflection of the bundle of sheets has the effect of bending it and exerting a tensile force on the paper fibers on the convex side of the curved bundle. At the same time, shearing forces are exerted on the paper at the location of the fold, and the forced deflection of the bundle causes pressure on the back of the fold in contact with the rollers. By the combination of these effects, the paper fibers are broken at the fold, and the tendency of the fold to reopen is essentially eliminated.
Pour augmenter la force de traction dans les fibres du papier et la proportion des fibres rompues dans la zone du pli, la paire de rouleaux est de préférence précédée d'une autre paire de rouleaux parallèles et opposés définissant entre eux une fente de passage d'un livret, au moins l'un desdits rouleaux étant entraîné en rotation et les rouleaux étant sollicités l'un vers l'autre, le plan défini par les axes de ladite paire de rouleaux étant normal à la direction d'avancement des livrets. L'espacement entre les paires de rouleaux est tel qu'un livret engagé dans la fente de passage des rouleaux aval se trouve encore engagé dans la fente de passage des rouleaux amont. Ainsi, les rouleaux amont s'opposent à la traction, dûe à la courbure de la liasse, exercée par les rouleaux aval sur les feuilles de papier lorsque le pli est engagé entre ceux-ci.To increase the tensile force in the paper fibers and the proportion of fibers broken in the fold area, the pair of rollers is preferably preceded by another pair of parallel and opposite rollers defining between them a slot for passage of a booklet, at least one of said rollers being driven in rotation and the rollers being biased towards each other, the plane defined by the axes of said pair of rollers being normal to the direction of advancement of the booklets. The spacing between the pairs of rollers is such that a booklet engaged in the roller passage slot downstream is still engaged in the passage slot of the upstream rollers. Thus, the upstream rollers oppose the traction, due to the curvature of the bundle, exerted by the downstream rollers on the sheets of paper when the fold is engaged between them.
Pour néanmoins limiter la force de traction exercée sur les feuilles de papier, la force de sollicitation l'un vers l'autre des rouleaux aval est de préférence nettement plus grande que celle des rouleaux amont au moment où le livret est engagé dans la fente de passage des rouleaux aval.To nevertheless limit the tensile force exerted on the sheets of paper, the biasing force towards each other of the downstream rollers is preferably significantly greater than that of the upstream rollers when the booklet is engaged in the slot of passage of the downstream rollers.
Suivant une forme de réalisation avantageuse de l'invention, des moyens communs de sollicitation sont prévus pour les deux paires de rouleaux, dont l'action est sélectivement appliquée à l'une ou l'autre de celles-ci. Ces moyens sont avantageusement constitués de deux éléments de transmission d'une force d'appui sur l'axe d'un des rouleaux de chaque paire, respectivement, la force d'appui étant appliquée directement à celui des éléments de transmission qui est associé aux rouleaux amont et indirectement, par contact entre ces éléments de transmission, à celui des éléments de transmission qui est associé aux rouleaux aval. Dans la forme de réalisation préférée, les éléments de transmission sont constitués de leviers pivotants ayant des extrémités libres en butée l'une contre l'autre et des parties intermédiaires en appui sur l'axe du rouleau associé.According to an advantageous embodiment of the invention, common biasing means are provided for the two pairs of rollers, the action of which is selectively applied to one or the other of these. These means advantageously consist of two elements for transmitting a bearing force on the axis of one of the rollers of each pair, respectively, the bearing force being applied directly to that of the transmission elements which is associated with the upstream rollers and indirectly, by contact between these transmission elements, to that of the transmission elements which is associated with the downstream rollers. In the preferred embodiment, the transmission elements consist of pivoting levers having free ends in abutment against one another and intermediate parts bearing on the axis of the associated roller.
D'autres détails et particularités de l'invention ressortiront de la description ci-après de plusieurs formes de réalisation, en référence aux dessins dans lesquels:
- la figure 1 est une vue schématique en élévation d'un dispositif de finition du pli de livrets;
- la figure 2 est une vue partielle à plus grande échelle du dispositif; et
- la figure 3 est une vue schématique d'une forme de réalisation préférée de l'invention.

- Figure 2 is a partial view on a larger scale of the device; and
- Figure 3 is a schematic view of a preferred embodiment of the invention.
Le dispositif de finition du pli de livrets comporte deux paires de rouleaux 10, 12, montés dans un bâti non-représenté, en succession selon un trajet de passage d'une liasse 14 de feuilles pliées suivant une ligne centrale. Les rouleaux inférieurs 10b, 12b sont chacun montés à rotation autour d'un axe fixe et entraînés en rotation par un moteur 16, par l'intermédiaire d'une courroie 18. Une courroie sans fin 20 est traînée autour des rouleaux 10b, 12b et autour d'un rouleau tendeur 22. Les rouleaux supérieurs 10a, 12a sont montés à rotation libre et à déplacement vertical; ils sont sollicités vers les rouleaux inférieurs 10b, 12b et en contact avec la courroie 20 par un ressort associé 24, 26, respectivement. Les rouleaux supérieurs 10a, 12a sont entraînés en rotation indirectement par contact à frottement avec la courroie 20, mais leur rotation est synchronisée par une courroie de synchronisation 28. Dans la deuxième paire 12 de rouleaux, le rouleau supérieur 12a est décalé par rapport au rouleau inférieur 12b en direction de la première paire 10 de rouleaux; la normale au plan défini par les axes des rouleaux 12a, 12b est donc inclinée par rapport à la direction d'avancement de la liasse 14. De ce fait, la courroie 20 subit une déflexion au contact avec le rouleau 12a. La liasse pliée 14 est déposée sur la courroie 20 devant la première paire 10 de rouleaux, le pli formant le bord avant de la liasse. Lorsqu'elle passe dans la fente formée entre le rouleau 10a et la courroie 20, le rouleau 10a est soulevé à l'encontre de la force du ressort 24 et une pression est exercée sur le pli de la liasse. Ensuite, comme il ressort plus clairement de la figure 2, la liasse 14 passe dans la zone où la courroie 20 est défléchie par le rouleau 12a. Une pression est alors exercée par la courroie 20 sur le dos du pli de la liasse 14, comme indiqué par une flèche à la figure 2. La liasse est déformée suivant le trajet de la courroie 20, avec une courbure convexe du côté de la courroie et une courbure concave du côté du rouleau 12a. Par cette courbure, les fibres du papier sont exposées à un effort de traction du côté de la courroie 20. En même temps, la déflexion de la liasse provoque des forces de cisaillement dans la zone du pli. L'action combinée de ces sollicitations fait rompre en grande partie les fibres du papier dans la zone du pli de la liasse 14. De ce fait, le livret sortant du dispositif ne présente plus une tendance à se rouvrir.The device for finishing the booklet fold comprises two pairs of
L'espacement entre les paires de rouleaux 10, 12 est de préférence suffisamment petit pour que la liasse 14, lorsque son pli est engagé entre la courroie 20 et le rouleau 12a, se trouve encore engagée dans la fente de passage entre la courroie 20 et le rouleau 10a. Lorsque la liasse 14 prend une forme courbe dûe à sa déflexion au contact avec le rouleau 12a, elle tend à avancer plus rapidement du côté convexe de la courbure. Toutefois, puisque la partie arrière de la liasse 14 reste engagée entre la courroie 20 et le rouleau 10a, cette partie arrière de la liasse ne peut suivre l'avancement plus rapide du côté convexe de la courbure, et la traction exercée sur les fibres du papier est donc augmentée. Pour assurer cet effet, il est important que l'entraînement des rouleaux 10b et 12b soit synchrone.The spacing between the pairs of
Dans la forme de réalisation préférée illustrée à la figure 3, la courroie 20 est remplacée par une tôle de guidage 30. Les rouleaux 10a, 10b et 12a, 12b sont tous accouplés comme représenté schématiquement à la figure 3, à un moteur d'entraînement 16, par l'intermédiaire d'une chaîne de transmission 32. Les rouleaux inférieurs 10b, 12b ont leurs axes montés de façon ajustable en hauteur dans un support excentrique 34 et 36, respectivement. La rotation de ces supports excentriques 34, 36 est commandée manuellement par un volant non-représenté, pour modifier l'écartement des rouleaux en fonction de l'épaisseur des livrets.In the preferred embodiment illustrated in Figure 3, the
Les rouleaux 10a, 12a sont montés à débattement dans des bras pivotants 38, 40, respectivement. La sollicitation des rouleaux 10a, 12a vers les rouleaux 10b, 12b est assurée par un mécanisme commun dont l'action est sélectivement appliquée au rouleau 10a et ensuite au rouleau 12a. Plus particulièrement, un levier pivotant 42 est en appui sur l'axe du rouleau 10a, et un levier pivotant analogue 44 est en appui sur l'axe du rouleau 12a. Les extrémités libres des leviers 42, 44 sont superposées et présentent des alésages alignés à travers lesquels passe une tige de traction 46. La tige de traction 46 porte un paquet de disques à ressort 48 qui s'appuie d'un côté sur un élément d'appui 50 et, de l'autre côté, sur un boulon 52 vissé sur l'extrémité libre de la tige de traction 46. Le paquet de disques à ressort 48 exerce donc une force de traction sur la tige 46, dont la tête appuye sur l'extrémité libre du levier 42 qui, à son tour, pousse sur l'extrémité libre du levier 44. La force de sollicitation des rouleaux 10a, 12a dépend du rapport entre la longueur du levier 42 ou 44 et la distance entre le point de pivotement de chaque levier et de sa zone d'appui sur l'axe du rouleau respectif. On peut varier ce rapport pour obtenir des forces de sollicitation différentes pour les paires de rouleaux 10, 12, malgré l'emploi d'un mécanisme commun.The
Lorsqu'une liasse entre dans la fente de passage formée entre les rouleaux 10a, 10b, le rouleau 10a est soulevé, et l'extrémité libre du levier 42 s'écarte de celle du levier 44. La force de traction exercée par la tige 46 est donc transmise sur l'axe du seul rouleau 10a, et le rouleau 12a est sollicité vers le rouleau 12b par simple gravitation. Lorsque la liasse passe ensuite dans la fente formée entre les rouleaux 12a, 12b, le rouleau 12a est soulevé, et le levier 44 est également soulevé. Puisque l'extrémité libre du levier 42 est en butée sur celle du levier 44, les deux leviers sont soulevés en même temps, à l'encontre de la force exercée à travers la tige 46. Puisque le levier 42 est soulevé par le levier 44, il n'appuye plus sur l'axe du rouleau 10a, et ce dernier n'est donc plus sollicité vers le rouleau 10b que par l'effet de gravité.When a bundle enters the passage slot formed between the
Comme la courroie 20 dans la forme de réalisation précédente, la tôle de guidage 30 force la liasse sur un trajet courbe pour rompre les fibres du papier dans la zone du pli.Like the
