Description

La présente invention est relative à une machine permettant de séparer des feuiiles de papier provenant d'une pile de feuilles, et notamment applicable à la séparation de billets de banque en vue de leur examen et de leur tri.The present invention relates to a machine for separating sheets of paper from a stack of sheets, and in particular applicable to the separation of banknotes for their examination and sorting.

Une machine de ce genre est par exemple décrite dans le brevet français N° 2 345 376 aux noms des demandeurs. Elle comporte essentiellement un ensemble de tambours creux montés sur une roue en rotation et animés d'un mouvement hypocycloïdal au cours duquel chaque tambour vient tour à tour au contact du sommet de la pile des billets vers une de leurs extrémités, le tambour arrivant au contact ayant simultanément son intérieur mis en communication avec une source de dépression de manière que, la dépression agissant à travers des ouvertures sur le billet au contact, celui-ci s'enroule partiellement autour de la périphérie du tambour quand le mouvement de ce tambour se poursuit, tandis que le tambour suivant agit pour retenir temporairement le billet immédiatement au dessous. Le billet ainsi soulevé de la pile par une de ses extrémités est ensuite transporté entre deux galets-presseurs à l'aide d'une roue creuse en rotation permanente dont l'intérieur est aussi relié à la source de dépression et qui agit tangentiellement par des ouvertures sur l'extrémité du billet en contact avec la pile pour le déplacer et l'amener entre les deux galets-presseurs.A machine of this kind is for example described in French patent No. 2,345,376 in the names of the applicants. It essentially comprises a set of hollow drums mounted on a rotating wheel and animated by a hypocycloidal movement during which each drum comes in turn to contact the top of the stack of banknotes towards one of their ends, the drum arriving in contact having simultaneously its interior placed in communication with a source of vacuum so that, the vacuum acting through openings on the banknote in contact, it coils partially around the periphery of the drum when the movement of this drum continues , while the next drum acts to temporarily hold the bill immediately below. The note thus lifted from the stack by one of its ends is then transported between two pinch rollers using a hollow wheel in permanent rotation whose interior is also connected to the source of vacuum and which acts tangentially by openings on the end of the banknote in contact with the stack to move it and bring it between the two pinch rollers.

Il est à remarquer que dans cette réalisation de la technique antérieure, seuls deux tambours consécutifs sont actifs à la fois et coopèrent pour détacher le premier billet de la pile et retenir le billet suivant; les autres tambours ne sont mis en service 1 un après l'autre, par paire avec le précédent, qu'au cours de la rotation progressive du support des tambours qui produit leur mouvement hypocycloïdal.It should be noted that in this embodiment of the prior art, only two consecutive drums are active at a time and cooperate to detach the first ticket from the stack and retain the next ticket; the other drums are put into service 1 one after the other, in pairs with the previous one, only during the progressive rotation of the support of the drums which produces their hypocycloidal movement.

L'invention a pour objet une machine séparatrice de feuilles de papier du genre décrit dans l'exemple précédent, mais de conception plus simplifiée grâce à une modification de la cinématique utilisée.The subject of the invention is a machine for separating sheets of paper of the kind described in the previous example, but of a more simplified design thanks to a modification of the kinematics used.

Suivant l'invention la machine séparatrice de feuilles de papier provenent d'une pile comporte:

  • - un support pour ladite pile,
  • - une structure mobile autour d'un axe parallèle au plan des feuilles au dessus dudit support,
  • - des tambours creux portés par ladite structure et montés de manière à pouvoir tourner autour de leurs axes respectifs parallèles à l'axe de ladite structure dans un sens opposé à celui de la structure, chaque tambour possédant au moins une ouverture à sa périphérie,
  • - des moyens permettant de créer temporairement une dépression à l'intérieur desdits tambours de manière que lorsqu'un tambour arrive au contact de la feuille au sommet de la pile, l'extrémité de cette feuille se détache de la pile et s'enroule partiellement sur la périphérie de ce tambour par effet de la dépression régnant à l'interieur de ce dernier, tandis qu'un autre tambour maintient en place la feuille immédiatement au dessous dans la pile,
  • - des moyens d'évacuation de la feuille ainsi partiellement enroulée dans la direction opposée à son extrémité détachée, et elle est caractérisée en ce que ladite structure est animée autour de son axe d'un mouvement oscillant par des moyens d'entraînement, et que lesdits tambours sont au nombre de deux et ne sont soumis à une dépression interne qu'au cours d'une demi-période du mouvement oscillant de ladite structure.
According to the invention, the machine for separating sheets of paper from a stack comprises:
  • - a support for said stack,
  • - a mobile structure around an axis parallel to the plane of the sheets above said support,
  • - hollow drums carried by said structure and mounted so as to be able to rotate around their respective axes parallel to the axis of said structure in a direction opposite to that of the structure, each drum having at least one opening at its periphery,
  • - Means for temporarily creating a vacuum inside said drums so that when a drum comes into contact with the sheet at the top of the stack, the end of this sheet detaches from the stack and is partially wound on the periphery of this drum by the effect of the depression prevailing inside the latter, while another drum holds the sheet in place immediately below in the stack,
  • - means for evacuating the sheet thus partially wound in the direction opposite to its detached end, and it is characterized in that said structure is animated around its axis of an oscillating movement by drive means, and that said drums are two in number and are subjected to an internal vacuum only during a half-period of the oscillating movement of said structure.

Les moyens d'entraînement de la structure sont de préférence réalisés en lui faisant comporter une fente dans laquelle peut coulisser un maneton excentré entrainé par un moteur.The drive means of the structure are preferably made by making it include a slot in which an eccentric crank pin driven by a motor can slide.

Ce même moteur entraine aussi un arbre à cames commandant des vannes branchées respectivement dans des circuits pneumatiques reliant l'intérieur des tambours à une source de dépression.This same engine also drives a camshaft controlling valves connected respectively in pneumatic circuits connecting the interior of the drums to a source of vacuum.

Les moyens d'évacuation de la feuille partiellement enroulée autour du tambour sont constitués par une roue creuse munie d'ouvertures qui est en contact avec le sommet de la pile et qui tourne autour d'un arbre parallèle à l'axe de la structure, l'arbre à cames précédent commandant aussi une vanne branchée dans un circuit pneumatique reliant la source de dépression à l'intérieur de la roue.The means for discharging the sheet partially wound around the drum are constituted by a hollow wheel provided with openings which is in contact with the top of the pile and which rotates around a shaft parallel to the axis of the structure, the previous camshaft also controlling a valve connected to a pneumatic circuit connecting the vacuum source inside the wheel.

La machine suivant l'invention est ainsi de réalisation plus simple que les machines de la technique antérieure, l'utilisation d'un mouvement oscillant permettant, moyennant un débit de la machine un peu moins grand, de toujours faire coopérer les deux tambours au cours d'une demi-période de leur mouvement cyclique, l'autre demi-période servant à les ramener à leur position d'origine.The machine according to the invention is thus simpler to produce than the machines of the prior art, the use of an oscillating movement allowing, with a flow rate of the machine a little less, to always make the two drums cooperate during of a half-period of their cyclic movement, the other half-period serving to bring them back to their original position.

Il en résulte pour la machine des avantages de prix par réduction du nombre des tambours limité à deux, et aussi d'encombrement par remplacement de la roue porteuse des tambours par un simple secteur circulaire. Un autre avantage consiste encore dans la réduction de la consommation d'air du fait que la source de dépression n'est branchée sur les tambours et la roue d'évacuation que pendant la moitié d'un cycle fonctionnement.This results in price advantages for the machine by reducing the number of drums limited to two, and also in space by replacing the drum carrying wheel with a simple circular sector. Another advantage consists in reducing the air consumption because the vacuum source is only connected to the drums and the evacuation wheel during half of an operating cycle.

L'invention sera mieux comprise en se référant à la description suivante et aux dessins annexés, donnés à titre d'exemples non limitatifs d'un mode de réalisation d'une machine séparatrice conforme à l'invention.

En se reportant aux figures 1 à 3, on voit en 10 la structure de la machine, mobile autour d'un axe 11 supporté par le bâti de la machine, cet axe 11 étant horizontal et parallèle au plan des feuilles de papier, par exemple des billets de banque, qui forment une pile 12 guidée dans un magasin 13. Des moyens annexes, qui seront décrits plus loin, permettent de maintenir le sommet de la pile de billets 12 à un niveau constant. L'axe 11 est disposé dans un plan vertical passant au voisinage d'une des extrémités de la pile 12. La structure mobile 10 a la forme générale d'un secteur circulaire d'axe 11 et porte, près de sa périphérie, deux tambours creux 14A, 14B dont l'espacement est choisi inférieur à la longueur des billets à séparer. Chaque tambour 14 est monté sur un arbre creux 15 qui peut tourillonner dans des roulements 36 de la structure 10.Referring to Figures 1 to 3, we see at 10 the structure of the machine, movable about an axis 11 supported by the machine frame, this axis 11 being horizontal and parallel to the plane of the sheets of paper, for example banknotes, which form a stack 12 guided in a store 13. Additional means, which will be described later, make it possible to maintain the top of the stack of notes 12 at a constant level. The axis 11 is arranged in a vertical plane passing in the vicinity of one of the ends of the stack 12. The mobile structure 10 has the general shape of a circular sector of axis 11 and carries, near its periphery, two drums hollow 14A, 14B whose spacing is chosen to be less than the length of the tickets to be separated. Each drum 14 is mounted on a hollow shaft 15 which can rotate in bearings 36 of the structure 10.

Sur chaque arbre 15 est calée une roue dentée 16 qui engrène avec la denture correspondante d'un secteur denté d'une couronne circulaire fixe 17, coaxiale à l'axe 11, de sorte que, lorsque la structure 10 oscille autour de l'axe 11, les tambours tournent autour de leur arbre 15 alternativement dans un sens et dans l'autre selon le sens de l'oscillation, en décrivant un mouvement hypocycloïdal.On each shaft 15 is wedged a toothed wheel 16 which meshes with the corresponding toothing of a toothed sector of a fixed circular crown 17, coaxial with the axis 11, so that, when the structure 10 oscillates around the axis 11, the drums rotate around their shaft 15 alternately in one direction and in the other according to the direction of oscillation, describing a hypocycloidal movement.

Le mouvement oscillatoire de la structure 10 est obtenu par l'intermédiaire d'un moteur électrique 18, fixé sur le bâti de la machine, qui entraine en rotation suivant la flèche F un maneton excentré 19 pouvant coulisser dans une fente 20 ménagée dans la structure 10. L'ensemble est dimensionné pour que, au cours de leur mouvement, la périphérie des tambours 14 soit juste en contact avec le sommet de la pile 12 maintenu à niveau constant.The oscillatory movement of the structure 10 is obtained by means of an electric motor 18, fixed on the frame of the machine, which rotates along the arrow F an eccentric crank pin 19 which can slide in a slot 20 formed in the structure 10. The assembly is dimensioned so that, during their movement, the periphery of the drums 14 is just in contact with the top of the stack 12 kept at constant level.

Chacun des tambours 14 est muni d'une ou plusieurs ouvertures 21 dirigées suivant une direction perpendiculaire à l'axe et faisant communiquer l'intérieur de l'arbre 15 et du tambour avec la surface externe de ce dernier.Each of the drums 14 is provided with one or more openings 21 directed in a direction perpendicular to the axis and communicating the interior of the shaft 15 and the drum with the external surface of the latter.

A l'extrémité du sommet de la pile 12 opposée à celle où les tambours 14 viennent affleurer les billets, est montée une roue creuse 22 qui joue le role de moyen d'évacuation du billet et qui tourne continuellement en restant en contact avec le sommet de la pile 12. La roue 22 sert à déplacer vers la droite le billet déjà partiellement enroulé sur le tambour 14A où il est repris par une paire de galets-presseurs 23, 24 pour être transporté vers un dispositif d'examen et de tri dans la direction de la flèche FI.At the end of the top of the pile 12 opposite to that where the drums 14 are flush with the banknotes, is mounted a hollow wheel 22 which acts as a means of discharging the banknote and which continuously rotates while remaining in contact with the top of the stack 12. The wheel 22 is used to move to the right the banknote already partially wound on the drum 14A where it is taken up by a pair of pinch rollers 23, 24 to be transported to an examination and sorting device in the direction of the arrow FI.

La roue 22, représentée en coupe à la figure 4, est montée, par l'intermédiaire d'un roulement 27 sur un arbre fixe parallèle à l'axe 11 et supporté par le bâti de la machine. L'arbre 25 est creux et la roue 22 comporte une pluralité d'ouvertures 26 (figure 1) mettant en communication l'intérieur de l'arbre 25 avec la surface externe de la roue 22. Celle-ci est entraînée en rotation autour de l'arbre 25 par un moteur 28, supporté par le bâti de la machine, et par l'intermédiaire d'un train d'engrenages 29.The wheel 22, shown in section in FIG. 4, is mounted, by means of a bearing 27 on a fixed shaft parallel to the axis 11 and supported by the frame of the machine. The shaft 25 is hollow and the wheel 22 has a plurality of openings 26 (FIG. 1) bringing the interior of the shaft 25 into communication with the external surface of the wheel 22. The latter is rotated around the shaft 25 by a motor 28, supported by the frame of the machine, and by means of a gear train 29.

La machine comporte également des circuits pneumatiques permettant de relier sélectivement d'une part l'intérieur des tambours 14A et/ou 14B, d'autre part l'intérieur de la roue 22, avec une source de dépression 30, par exemple une pompe ou un ventilateur, éventuellement associée à un réservoir sous vide, par l'intermédiaire d'une douille 34 et de conduites souples 35 de raccordement, et de vannes 31 A, 31 B et 32. Ces vannes sont commandées par un arbre à cames 33 entrainé par le même moteur 18 que la structure 10. Les cames respectives de commande des vannes 31 A, 31 B et 32 sont calées de manière à commander ces vannes en synchronisme avec le mouvement de la structure 10, et par suite à ne mettre l'intérieur des tambours 14 et de la roue 22 en dépression qu'à des instants déterminés pendant la demi-période active du mouvement oscillant de la structure 10. La figure 3A montre de profil un exemple de came coopérant avec sa vanne associée. Les vannes 31 et 32, au lieu d'être à commande directe, peuvent être remplacées par des électrovannes.The machine also comprises pneumatic circuits making it possible to selectively connect on the one hand the interior of the drums 14A and / or 14B, on the other hand the interior of the wheel 22, with a source of vacuum 30, for example a pump or a fan, possibly associated with a vacuum tank, by means of a sleeve 34 and flexible connecting pipes 35, and of valves 31 A, 31 B and 32. These valves are controlled by a camshaft 33 driven by the same motor 18 as the structure 10. The respective control cams of the valves 31 A, 31 B and 32 are set so as to control these valves in synchronism with the movement of the structure 10, and consequently do not put the inside the drums 14 and the wheel 22 in vacuum only at instants determined during the active half-period of the oscillating movement of the structure 10. FIG. 3A shows in profile an example of a cam cooperating with its associated valve. Valves 31 and 32, instead of being directly controlled, can be replaced by solenoid valves.

Le fonctionnement de la machine se déroule alors de la façon suivante:

  • - Partant de la position origine représentée à la figure 1, les tambours 14A et 14B sont «au point mort arrière» du maneton 19, le rouleau 14A étant au contact du billet au sommet de la pile 12 avec ses ouvertures 21 dirigées vers le billet.
  • - Le maneton 19 effectuant une rotation suivant le sens de la flèche F, la structure 10 amorce une demi-oscillation vers la droite, les tambours 14A et 14B tournant, eux, dans le sens horaire sur la vue de la figure 1. Le calage de la came relative au tambour 14A sur l'arbre 33 est tel que la vanne 31 A met alors l'intérieur de ce tambour en dépression de sorte que l'extrémité du billet au sommet de la pile 12 est aspirée par ce tambour et que le billet adhère à la périphérie du tambour autour de laquelle il tend à s'enrouler au fur et à mesure que le mouvement de la structure 10 se poursuit vers la droite.
The operation of the machine then proceeds as follows:
  • - Starting from the original position shown in FIG. 1, the drums 14A and 14B are "at rear dead center" of the crankpin 19, the roller 14A being in contact with the banknote at the top of the stack 12 with its openings 21 directed towards the banknote .
  • - The crankpin 19 rotating in the direction of the arrow F, the structure 10 initiates a half-oscillation to the right, the drums 14A and 14B rotating, them, clockwise in the view of Figure 1. The setting of the cam relative to the drum 14A on the shaft 33 is such that the valve 31 A then puts the interior of this drum in vacuum so that the end of the bill at the top of the stack 12 is sucked by this drum and that the ticket adheres to the periphery of the drum around which it tends to wind as the movement of the structure 10 continues to the right.

La figure 2 montre la position de la structure 10 à la fin de sa demi-oscillation vers la droite, c'est-à-dire au «point mort avant» du maneton 19. Le billet supérieur de la pile 12 est alors enroulé sur environ une demi-circonférence du tambour 14A tandis que le tambour 14B vient d'arriver au contact du billet immédiatement au-dessous dans la pile. A ce stade, les cames de l'arbre 33 agissent respectivement: sur la vanne 31 A pour faire cesser la dépression à l'intérieur du tambour 14A et relâcher le billet à demi-enroulé à sa périphérie; sur la vanne 31 B pour au contraire faire agir la dépression dans le tambour 14B et retenier le billet suivant de la pile; et sur la vanne 32 pour faire agir la dépression à l'intérieur de la roue 22 qui peut alors entraîner le billet supérieur, relâché par le tambour 14A, vers les galets 23, 24.FIG. 2 shows the position of the structure 10 at the end of its half-oscillation to the right, that is to say at the "front dead center" of the crank pin 19. The upper banknote of the stack 12 is then wound on about a half circumference of the drum 14A while the drum 14B has just come into contact with the banknote immediately below in the stack. At this stage, the cams of the shaft 33 act respectively: on the valve 31 A to stop the vacuum inside the drum 14A and release the half-wound bill at its periphery; on the valve 31 B to on the contrary cause the depression in the drum 14B to act and retain the next banknote from the stack; and on the valve 32 to act the vacuum inside the wheel 22 which can then drive the upper bill, released by the drum 14A, towards the rollers 23, 24.

Le billet supérieur de la pile ainsi séparé et évacué, la structure 10 repart vers la gauche pour une demi-oscillation «à vide» au cours de laquelle la dépression est supprimée dans les tambours 14A er 14B; ceux-ci étant désactivés, ils ne jouent aucun rôle tendant à prélever un billet, mais roulent simplement tour à tour sur le sommet de la pile dans le sens anti-horaire. Il en va de même pour la roue 22.The upper banknote of the stack thus separated and evacuated, the structure 10 departs to the left for a half-oscillation "empty" during which the vacuum is removed in the drums 14A and 14B; these being deactivated, they do not play any role tending to withdraw a ticket, but simply roll in turn on the top of the pile in an anti-clockwise direction. The same goes for wheel 22.

Quand la seconde demi-oscillation de la structure 10 vers la gauche prend fin, celle-ci se retrouve dans la position initiale d'origine décrite à la figure 1, et un autre cycle d'oscillation va se répéter de façon analogue pour le prélèvement du nouveau billet occupant le sommet de la pile.When the second half-oscillation of the structure 10 to the left ends, it is found in the original original position described in Figure 1, and another cycle of oscillation will be repeated analogously for the sampling of the new note occupying the top of the stack.

La figure 5 représente schématiquement un moyen permattant d'assurer la constance du niveau des billets de la pile 12 dans le magasin 13 (fig. 1). Deux bras 40 servant de palpeurs de niveau du sommet de la pile 12 encadrent la roue 22 et sont montés pivotants autour d'un axe 41. Une palette métallique 42 est solidaire des bras 40 et coopère avec un capteur de proximité 43, par exemple du type à variation de réluctance; celui-ci met sous ou hors tension un moteur électrique (non représenté) commandant le dispositif de déplacement vers le haut 44 (fig. 1) de la plaque de fond du magasin 13 contenant la pile de billets 12, suivant que la palette 42 est à une distance du capteur supérieure ou inférieure à un seuil déterminé.FIG. 5 schematically represents a permattant means of ensuring the constancy of the level of the banknotes of the stack 12 in the magazine 13 (FIG. 1). Two arms 40 serving as level probes from the top of the stack 12 surround the wheel 22 and are pivotally mounted about an axis 41. A metal pallet 42 is integral with the arms 40 and cooperates with a proximity sensor 43, for example of the reluctance variation type; it turns on or off an electric motor (not shown) controlling the upward movement device 44 (fig. 1) of the bottom plate of the magazine 13 containing the stack of notes 12, depending on whether the pallet 42 is at a distance from the sensor above or below a determined threshold.

- est évident que l'invention n'est pas limitée au seul mode de réalisation qui a été décrit à titre d'exemple, et que des modifications peuvent y être apportées sans sortir de son domaine, notamment quant aux moyens d'entraînement de la structure dans son mouvement oscillant et à l'obtention de la commande des vannes en synchronisme avec ce mouvement oscillant.- It is obvious that the invention is not limited to the single embodiment which has been described by way of example, and that modifications can be made thereto without departing from its field, in particular as regards the drive means structure in its oscillating movement and in obtaining control of the valves in synchronism with this oscillating movement.
