Description

La présente invention concerne un dispositif d'empilage de cahiers sous forme de cartouche, du type comportant une tête d'empilage à chemin d'amenée vertical d'une nappe de cahiers du haut vers le bas sur une table d'empilage horizontale, lesdits cahiers venant reposer sur la table d'empilage cote à côte de manière à former une cartouche de cahiers, le chemin d'amenée vertical des cahiers étant défini entre une première série de courroies d'entraínement définissant une paroi verticale intérieure et une seconde série de courroies d'entraínement extérieures s'étendant en regard de la paroi verticale intérieure jusqu'au ras de la partie supérieure des cahiers reposant sur la table d'empilage en cartouche au niveau du point d'empilage, un dispositif de réglage manuel ou automatique étant, de préférence, prévu pour amener les courroies extérieures au ras des cahiers de la cartouche en formation en fonction des dimensions des cahiers à empiler. Un tel dispositif est connu de US-A-4 172 531.The present invention relates to a device for stacking notebooks in the form of a cartridge, of the type comprising a head stacking a vertical sheet of notebooks from top to bottom on a horizontal stacking table, said notebooks coming to rest on the stacking table side by side to form a cartridge of notebooks, the path of vertical supply of the notebooks being defined between a first series of drive belts defining a wall vertical interior and a second set of belts external drive extending opposite the wall vertical inside flush with the top of the notebooks resting on the cartridge stacking table at stacking point level, manual adjustment device or automatic being preferably provided to bring the external straps flush with the notebooks of the cartridge in training according to the dimensions of the notebooks to be stacked. A such a device is known from US-A-4,172,531.

La première série de courroies forme donc une paroi verticale intérieure de la tête d'empilage, jusqu'à la table d'empilage tandis que la seconde série de courroies en regard de ladite paroi s'étend à l'extérieur de la tête d'empilage jusqu'au ras de l'extrémité supérieure des cahiers reposant sur la table d'empilage au point d'empilage. De ce fait, les courroies extérieures sont en contact avec les cahiers reposant sur la table d'empilage en cartouche en sortie du point d'empilage ce qui assure une bonne mise en place desdits cahiers dans la cartouche. La hauteur des courroies extérieures est donc, de préférence, réglable en fonction de la hauteur des cahiers à empiler.The first series of belts therefore forms a vertical wall inside of the stacking head, up to the stacking table while the second series of belts opposite said wall extends outside the stacking head to flush with the upper end of the notebooks resting on the stacking table at the stacking point. As a result, external belts are in contact with the notebooks resting on the cartridge stacking table at the outlet of the stacking point which ensures good positioning said notebooks in the cartridge. The height of the belts is therefore preferably adjustable according to the height of the notebooks to be stacked.

Au cours d'un empilage, un bourrage de cahiers peut survenir, par exemple du fait de la présence de cahiers jetés accidentellement sur les convoyeurs d'amenée des cahiers ou encore du fait de cahiers mal pliés ou bien lorsque ceux-ci se collent entre eux et glissent mal les uns par rapport aux autres au niveau du point d'empilage.During stacking, a jam of notebooks may occur, for example due to the presence of discarded notebooks accidentally on the conveyors of the notebooks or again due to improperly folded notebooks or when these stick to each other and slip poorly relative to each other others at the stacking point.

Une surépaisseur due au bourrage des cahiers au point d'empilage survient alors et cette surépaisseur peut entraíner une détérioration du matériel d'empilage telle qu'une sortie des courroies d'entraínement hors de leurs guides ou encore la casse de certaines pièces mécaniques.An excess thickness due to the padding of notebooks to the point stacking occurs and this extra thickness can cause deterioration of the stacking material such that an output of the drive belts out of their guides or the breakage of certain mechanical parts.

Afin d'éviter de telles détériorations, on a proposé des dispositifs de détection d'un bourrage permettant la détection d'une surépaisseur au point d'empilage et qui, en particulier, commandent l'arrêt de la production ou la déviation de la production vers un autre dispositif d'empilage lorsqu'un bourrage est détecté.In order to avoid such deterioration, proposals have been made jam detection devices allowing the detection of an excess thickness at the stacking point and which, in particular, order the cessation of production or the diversion of production to another device stacking when a jam is detected.

Ces dispositifs de détection peuvent comprendre une cellule de détection optique de la surépaisseur, ou bien les courroies d'entraínement extérieures des cahiers peuvent être montées sur un châssis basculant qui, lors d'une surépaisseur, bascule et actionne un interrupteur commandant l'arrêt de la production. These detection devices may include a cell optical excess thickness detection, or external drive belts for notebooks can be mounted on a tilting frame which, during a overthickness, switches and actuates a commanding switch stopping production.

De tels dispositifs, s'ils permettent d'éviter une détérioration du matériel en commandant l'arrêt du fonctionnement du dispositif, ne permettent pas, en conséquence, une continuité dans la production et un opérateur doit intervenir pour pouvoir remettre en route cette production vers le dispositif d'empilage.Such devices, if they make it possible to avoid deterioration of the equipment by ordering the shutdown of the operation of the device, do not allow, in consequence, a continuity in the production and a operator must intervene to be able to restart this production to the stacking device.

De plus, il est nécessaire de déterminer pour chaque production une épaisseur autorisée et une épaisseur interdite correspondant à la détection d'un bourrage et ce réglage étant tributaire de l'opérateur, il ne garantit pas toujours une bonne détection d'un bourrage.In addition, it is necessary to determine for each production an authorized thickness and a prohibited thickness corresponding to the detection of a jam and this setting being dependent on the operator, it does not always guarantee good detection of a jam.

En outre, ces dispositifs de détection du bourrage sont relativement lents à réagir. Ainsi, ces dispositifs détectent une surépaisseur à un moment où le bourrage est déjà effectif, un cahier s'étant par exemple immobilisé depuis longtemps en travers du point d'empilage et ayant provoqué cette surépaisseur caractéristique du bourrage. A vitesse de production élevée pour de grosses épaisseurs de cahiers, la détection du bourrage n'intervient pas de manière suffisamment rapide pour empêcher certaines courroies du chemin d'amenée vertical de sortir de leurs guides ou pour prévenir la casse de certaines pièces mécaniques.In addition, these jam detection devices are relatively slow to respond. So these devices detect an extra thickness at a time when the jam is already workforce, a notebook having, for example, been immobilized since long across the stacking point and causing this extra thickness characteristic of the stuffing. At speed of high production for large thicknesses of notebooks, the jam detection does not occur so fast enough to prevent certain belts from vertical path to exit their guides or to prevent breakage of certain mechanical parts.

Afin de pallier cet inconvénient, la présente invention a pour but de proposer un dispositif d'empilage du type mentionné comportant un dispositif permettant à la fois la détection rapide du bourrage mais permettant également d'évacuer ce bourrage au-delà du point d'empilage sans que la production soit arrêtée.In order to overcome this drawback, the present invention has aim of proposing a stacking device of the type mentioned including a device allowing both the rapid jam detection but also allowing to evacuate this jam beyond the stacking point without the production be stopped.

A cet effet, la présente invention a pour objet un dispositif d'empilage de cahiers sous forme de cartouche, du type comportant une tête d'empilage à chemin d'amenée vertical d'une nappe de cahiers du haut vers le bas sur une table d'empilage horizontale, lesdits cahiers venant reposer sur la table d'empilage côte à côte de manière à former une cartouche de cahiers, le chemin d'amenée vertical des cahiers étant défini entre une première série de courroies d'entraínement définissant une paroi verticale intérieure et une seconde série de courroies d'entraínement extérieures s'étendant en regard de ladite paroi verticale intérieure jusqu'au ras de la partie supérieure des cahiers reposant sur la table d'empilage en cartouche au point d'empilage, un dispositif de réglage manuel ou automatique étant, de préférence, prévu pour régler la hauteur des courroies extérieures et les amener au ras des cahiers de la cartouche en formation en fonction des dimensions des cahiers à empiler, caractérisé en ce qu'il comporte un dispositif de détection et d'évacuation d'une accumulation de cahiers ou bourrage de cahiers, comportant des moyens de mesure de la vitesse de défilement des cahiers dans le chemin d'amenée vertical, au moins des moyens de comparaison de cette vitesse mesurée par rapport à une valeur de vitesse correspondant à la vitesse d'avancement théorique des cahiers dans le dispositif d'empilage, ainsi que des moyens agencés pour effacer au moins partiellement du chemin d'amenée vertical les courroies d'entraínement extérieures, lors de la détection d'une vitesse de défilement des cahiers significative d'un bourrage et pour ramener lesdites courroies à leur position initiale lors de la détection d'une vitesse de défilement correspondant à la vitesse d'avancement théorique des cahiers.To this end, the subject of the present invention is a device stacking of notebooks in the form of a cartridge, of the type comprising a stacking head with vertical feed path a tablecloth of notebooks from top to bottom on a table horizontal stacking, said notebooks coming to rest on the stacking table side by side so as to form a notebook cartridge, the vertical path of the notebooks being defined between a first series of belts drive defining an interior vertical wall and a second series of external drive belts extending opposite said interior vertical wall up to the top of the notebooks resting on the cartridge stacking table at the stacking point, a manual or automatic adjustment device being, of preferably designed to adjust the height of the belts and bring them flush with the notebooks on the cartridge in training according to the dimensions of the notebooks to stack, characterized in that it comprises a device for detection and evacuation of an accumulation of notebooks or padding of notebooks, comprising means for measuring the scrolling speed of notebooks in the feed path vertical, at least means for comparing this speed measured against a speed value corresponding to the theoretical advancement speed of the notebooks in the stacking device, as well as means arranged for at least partially clear from the vertical path the external drive belts, when detection of a scrolling speed of the notebooks significant of a jam and to bring back said belts to their original position when detecting a scrolling speed corresponding to the forward speed theoretical notebooks.

Ainsi, lorsqu'un cahier se bloque, les autres viennent en butée derrière et s'arrêtent progressivement entre les courroies intérieures et extérieures et les cahiers ne peuvent plus glisser vers la table d'empilage. Ce blocage, ou plus précisément cette accumulation des cahiers située sensiblement au point d'empilage, provoque donc une modification mesurable de la vitesse de défilement des cahiers. De manière avantageuse, la mesure de la vitesse et la comparaison avec la vitesse théorique permettent de détecter une discordance entre la vitesse mesurée et la vitesse théorique, ce qui commande alors l'effacement au moins partiel des courroies d'entraínement extérieures du chemin d'amenée vertical.So when one notebook hangs, the others come in stop behind and gradually stop between interior and exterior belts and notebooks do can no longer slide towards the stacking table. This blockage, or more precisely this accumulation of notebooks located substantially at the stacking point, therefore causes measurable change in frame rate notebooks. Advantageously, measuring the speed and comparison with theoretical speed allow detect a discrepancy between the measured speed and the theoretical speed, which then commands erasure at less partial of the external drive belts of the vertical driveway.

De ce fait, les courroies extérieures étant effacées du chemin d'amenée vertical au voisinage du point d'empilage où a lieu l'accumulation de cahiers, lesdites courroies ne bloquent plus l'avancée de l'amas de cahiers et on libère l'accumulation des cahiers bloqués, ceux-ci étant alors entraínés dans la cartouche en formation sur la table d'empilage.Therefore, the outer belts being erased from the vertical feed path near the stacking point where the accumulation of notebooks takes place, said belts do not block more the advance of the pile of notebooks and we release the accumulation of blocked notebooks, these then being entrained in the cartridge in formation on the table stacking.

Dès que la vitesse des cahiers dans le chemin d'amenée vertical est mesurée et détectée conforme à la vitesse théorique, on ramène les courroies d'entraínement extérieures à leur position initiale de fonctionnement.As soon as the speed of the notebooks in the driveway vertical is measured and detected according to speed theoretical, we bring back the external drive belts to their initial operating position.

Ainsi, en effaçant les courroies d'entraínement extérieures, de préférence dès détection d'une vitesse de défilement des cahiers différente de la vitesse théorique, on a laissé s'évacuer l'accumulation de cahiers qui s'est trouvée entraínée au sein de la cartouche en formation sans qu'il soit nécessaire de stopper l'empilage des cahiers et avant qu'une surépaisseur liée au bourrage ne se forme réellement comme dans les systèmes par détection de surépaisseur.Thus, by erasing the external drive belts, preferably upon detection of a running speed of the notebooks different from the theoretical speed, we left get rid of the accumulation of notebooks that has been found entrainée within the cartridge in formation without it be necessary to stop stacking notebooks and before that an extra thickness due to the stuffing does not really form as in the systems for detection of excess thickness.

Les cahiers mal positionnés du fait du bourrage peuvent ensuite être retirés ultérieurement de la cartouche par un opérateur.Improperly positioned notebooks due to jamming can then be removed later from the cartridge by a operator.

Un tel dispositif de détection et d'évacuation d'un bourrage de cahiers est plus simple à mettre en oeuvre puisqu'il n'implique plus un dispositif nécessitant un réglage tel que la détermination de la surépaisseur à détecter en fonction de l'épaisseur des cahiers en production. Ce dispositif permet en outre une détection rapide et une correction également rapide et simple sans arrêt de la production.Such a jam detection and removal device of notebooks is simpler to implement since no longer involves a device requiring adjustment such as determining the excess thickness to be detected as a function of the thickness of the notebooks in production. This device allows furthermore rapid detection and correction also fast and simple without stopping production.

De plus, même si l'opérateur oublie d'enlever un bourrage au sein de la cartouche en formation la production se poursuit.In addition, even if the operator forgets to remove a jam at within the cartridge in formation production continues.

De préférence, les moyens de mesure de la vitesse de défilement des cahiers dans le chemin d'amenée vertical sont constitués par un capteur mécanique associé à un détecteur inductif. Le capteur mécanique peut être une roue montée libre en rotation et maintenue en contact avec les cahiers défilant dans le chemin d'amenée vertical, dont on mesure la vitesse de rotation pour mesurer la vitesse de défilement des cahiers. Ainsi, la roue est de préférence une roue évidée symétriquement et le détecteur inductif émet un signal électrique dont la fréquence est proportionnelle à la vitesse de rotation de la roue. Cette information concernant la mesure de la vitesse est ensuite envoyée vers une unité logique comportant les moyens de comparaison qui traitent ladite information en comparant la vitesse détectée à une vitesse théorique de défilement des cahiers dans la tête d'empilage. De préférence, l'unité logique comporte également des moyens de lecture des informations reçues des moyens de mesure de la vitesse, une mémoire dans laquelle est stockée au moins la vitesse théorique d'avancement des cahiers ainsi que des moyens de commande des moyens agencés pour effacer les courroies extérieures.Preferably, the means for measuring the speed of scrolling notebooks in the vertical path are constituted by a mechanical sensor associated with a detector inductive. The mechanical sensor can be a mounted wheel free to rotate and kept in contact with the notebooks parading in the vertical path, which we measure rotation speed to measure the running speed of notebooks. Thus, the wheel is preferably a hollowed out wheel symmetrically and the inductive sensor emits a signal electric whose frequency is proportional to the speed wheel rotation. This information regarding the speed measurement is then sent to a unit logic comprising the means of comparison which treat said information by comparing the detected speed to a theoretical speed of scrolling of notebooks in the head stacking. Preferably, the logic unit also includes means for reading information received from means for speed measurement, a memory in which is stored at least the theoretical speed of advancement of the notebooks as well only control means means arranged to erase the outer belts.

Selon une première forme de réalisation, les moyens agencés pour effacer au moins partiellement du chemin d'amenée vertical les courroies d'entraínement extérieures et les ramener à leur position initiale, sont constitués par des moyens d'entraínement en translation des courroies d'entraínement extérieures, le long de la paroi verticale, en écartement de la cartouche en formation lors de la détection d'une vitesse de défilement des cahiers significative d'une accumulation de cahiers ou bourrage et en rapprochement de la cartouche jusqu'au ras des cahiers lors de la détection d'une vitesse de défilement correspondant à la vitesse d'avancement théorique des cahiers.According to a first embodiment, the means arranged to at least partially clear from the feed path vertical the external drive belts and the return to their original position, are formed by means of translational drive of the belts external drive along the vertical wall, in spacing of the cartridge in formation during detection of a scrolling speed of the notebooks significant of a accumulation of notebooks or jamming and reconciliation of the cartridge to the bottom of the notebooks when detecting a scrolling speed corresponding to the forward speed theoretical notebooks.

De préférence, les courroies sont montées sur un support et les moyens d'entraínement en translation des courroies extérieures sont constitués par des moyens d'actionnement pneumatiques ou hydrauliques tels que des vérins montés sur la tête d'empilage et reliés au support des courroies pour entraíner celui-ci en translation le long de la paroi intérieure, en écartement et en rapprochement des courroies extérieures de la cartouche en formation sur la table d'empilage.Preferably, the belts are mounted on a support and the drive means in translation of the belts external are constituted by actuating means pneumatic or hydraulic such as cylinders mounted on the stacking head and connected to the belt support for drive it in translation along the wall interior, in spacing and in approximation of the belts of the cartridge being formed on the table stacking.

Selon une autre forme de réalisation de l'invention, les moyens agencés pour effacer au moins partiellement du chemin d'amenée vertical les courroies extérieures et les ramener à leur position initiale sont constitués par des moyens d'entraínement en pivotement des courroies extérieures en écartement et en rapprochement de la paroi verticale intérieure. Ainsi, les courroies extérieures sont écartées par pivotement du chemin d'amenée vertical lors de la détection d'une vitesse significative d'un risque de bourrage ce qui libère le passage à une accumulation de cahiers puis sont ensuite ramenées à leur position initiale par rapprochement par pivotement.According to another embodiment of the invention, the means arranged to at least partially erase from the path vertical belts and bring them back to their initial position are formed by means for pivoting drive of the external belts in spacing and approaching the vertical wall interior. Thus, the outer belts are spread by pivoting the vertical feed path during the detection of a significant speed of a risk of jamming which frees the passage to an accumulation of notebooks then are then returned to their original position by reconciliation by pivoting.

La présente invention a également pour objet un dispositif de détection et d'évacuation automatique d'une accumulation de cahiers ou bourrage de cahiers destiné à un dispositif d'empilage de cahiers sous forme de cartouche, du type comportant une tête d'empilage à chemin d'amenée vertical d'une nappe de cahiers du haut vers le bas sur une table d'empilage horizontale, lesdits cahiers venant reposer sur la table d'empilage côte à côte de manière à former une cartouche de cahiers, le chemin d'amenée vertical des cahiers étant défini entre une première série de courroies d'entraínement définissant une paroi verticale intérieure et une seconde série de courroies d'entraínement extérieures s'étendant en regard de ladite paroi verticale intérieure jusqu'au ras de la partie supérieure des cahiers reposant sur la table d'empilage en cartouche, un dispositif de réglage manuel ou automatique étant, de préférence, prévu pour régler la hauteur des courroies extérieures et les amener au ras des cahiers de la cartouche en formation en fonction des dimensions des cahiers à empiler, caractérisé en ce qu'il comporte des moyens de mesure de la vitesse de défilement des cahiers dans le chemin d'amenée vertical du dispositif d'empilage, au moins des moyens de comparaison de cette vitesse mesurée par rapport à une valeur de vitesse correspondant à la vitesse d'avancement théorique de la nappe dans ledit dispositif d'empilage ainsi que des moyens agencés pour effacer au moins partiellement du chemin d'amenée vertical les courroies d'entraínement extérieures, lors de la détection d'une vitesse de défilement des cahiers significative d'un bourrage et ramener lesdites courroies à leur position initiale lors de la détection d'une vitesse de défilement correspondant à la vitesse d'avancement théorique des cahiers.The present invention also relates to a device for automatic detection and evacuation of an accumulation of notebooks or padding of notebooks for a device stacking of notebooks in the form of a cartridge, of the type comprising a stacking head with vertical feed path a tablecloth of notebooks from top to bottom on a table horizontal stacking, said notebooks coming to rest on the stacking table side by side so as to form a notebook cartridge, the vertical path of the notebooks being defined between a first series of belts drive defining an interior vertical wall and a second series of external drive belts extending opposite said interior vertical wall up to the top of the notebooks resting on the cartridge stacking table, an adjustment device manual or automatic being preferably provided for adjusting the height of the outer belts and bring them flush with the Cartridge notebooks in training based on dimensions of stackable notebooks, characterized in that includes means for measuring the running speed of notebooks in the vertical path of the device stacking, at least means for comparing this measured speed in relation to a speed value corresponding to the theoretical advancement speed of the water table in said stacking device as well as arranged means to at least partially clear from the feed path vertical the external drive belts, when detection of a scrolling speed of the notebooks significant jamming and reduce said belts to their initial position when detecting a speed of scrolling corresponding to the theoretical forward speed notebooks.

Un tel dispositif reprend l'ensemble des caractéristiques énoncées ci-dessus.Such a device incorporates all of the characteristics set out above.

On décrira maintenant l'invention plus en détail en référence au dessin dans lequel :

  • la figure 1 représente une vue latérale partielle d'un dispositif d'empilage selon l'invention ;
  • les figures 2a, 2b, 2c, 2d, 2e et 2f représentent les différentes étapes de fonctionnement du dispositif de la figure 1 lors de l'apparition d'un bourrage.
    • The invention will now be described in more detail with reference to the drawing in which:
  • Figure 1 shows a partial side view of a stacking device according to the invention;
  • Figures 2a, 2b, 2c, 2d, 2e and 2f show the different stages of operation of the device of Figure 1 when a jam occurs.

    • Un dispositif d'empilage selon l'invention comporte une tête d'empilage E à chemin d'amenée vertical des cahiers C sur une table d'empilage horizontale T.A stacking device according to the invention comprises a head stacking E with vertical path of the notebooks C on a horizontal stacking table T.

    Le chemin d'amenée vertical des cahiers C est défini entre deux séries de courroies d'entraínement 1, 2 des cahiers C. Une première série de courroies 1 (représentées en pointillés) définit une paroi verticale intérieure dans la tête d'empilage E et une seconde série de courroies 2 (représentées en pointillés) est ménagée en regard de ladite paroi verticale intérieur vers l'extérieur de la tête d'empilage, les cahiers C étant guidés entre la paroi verticale intérieure et les courroies d'entraínement extérieures 2.The vertical path of the notebooks C is defined between two sets of drive belts 1, 2 of notebooks C. A first series of belts 1 (shown in dotted line) defines an interior vertical wall in the stacking head E and a second set of belts 2 (shown in dotted lines) is arranged opposite said vertical wall inside towards the outside of the head stacking, notebooks C being guided between the wall vertical interior and drive belts exterior 2.

    Ces courroies d'entraínement extérieures 2 sont montées sur un support et, plus précisément, lesdites courroies 2 sont tendues autour d'un châssis 3 s'étendant le long de la paroi verticale intérieure, les courroies 2 étant au moins guidées sur des galets de guidage 4 montés libres en rotation à l'extrémité inférieure du châssis 3.These external drive belts 2 are mounted on a support and, more precisely, said belts 2 are stretched around a frame 3 extending along the wall vertical inside, the belts 2 being at least guided on guide rollers 4 mounted free to rotate at the lower end of the chassis 3.

    Les cahiers C arrivent donc dans le chemin d'amenée vertical guidés vers la table d'empilage T du haut vers le bas entre les courroies intérieures 1 et les courroies extérieures 2 (figure 2a).Notebooks C therefore arrive in the vertical path guided towards the stacking table T from top to bottom between the internal belts 1 and the external belts 2 (Figure 2a).

    A la sortie dudit chemin, les cahiers C reposent avec leur dos sur la table d'empilage T les uns derrière les autres de manière à former une cartouche.At the end of said path, notebooks C rest with their back on stacking table T one behind the other so as to form a cartridge.

    L'extrémité du châssis 3 portant les courroies extérieures 2 repose au-dessus de la cartouche de cahiers en formation au niveau du point d'empilage comme cela est visible à la figure 1 et les courroies 2 s'étendent le long de la paroi verticale intérieure jusqu'au ras de la partie supérieure des cahiers de telle sorte qu'elles sont en contact avec ladite partie supérieure des cahiers C juste après le point d'empilage et contribuent ainsi à la bonne mise en place des cahiers C sous forme de cartouche.The end of the chassis 3 carrying the external belts 2 rests above the cartridge of notebooks in formation at stacking point level as shown in the figure 1 and the belts 2 extend along the vertical wall interior flush with the top of the notebooks so that they are in contact with said part top of notebooks C just after the stacking point and thus contribute to the proper implementation of C notebooks under cartridge shape.

    La hauteur du châssis 3 dans la tête d'empilage E est réglable par un dispositif de réglage manuel ou automatique en fonction des dimensions des cahiers C à empiler sur la table d'empilage T de manière à amener les courroies extérieures 2 au ras des cahiers de la cartouche en formation. Ce réglage est un réglage standard.The height of the chassis 3 in the stacking head E is adjustable by manual or automatic adjustment device depending on the dimensions of the C notebooks to be stacked on the stacking table T so as to bring the belts external 2 flush with the notebooks of the cartridge in training. This setting is a standard setting.

    La tête d'empilage E comporte en outre un dispositif de détection et d'évacuation d'un bourrage de cahiers au niveau du point d'empilage.The stacking head E further comprises a device for detection and removal of a jam of notebooks at the level from the stacking point.

    Ce dispositif comporte des moyens de mesure de la vitesse de défilement de la nappe de cahiers C dans le chemin d'amenée verticale. Ces moyens de mesure sont ici constitués d'un capteur mécanique tel qu'une roue 5 portée par un bras 6 articulé sur le châssis 3 à l'aide d'un ressort 7 assurant toujours un contact de la roue 5 avec la nappe de cahiers défilant et associée à un détecteur inductif 8. La roue 5 libre en rotation est entraínée en rotation par le défilement des cahiers C, en conséquence lorsque le défilement des cahiers C est perturbé, la vitesse de rotation de la roue 5 indicatrice de la vitesse de défilement de la nappe est modifiée. La roue 5 est évidée de manière symétrique et le détecteur inductif émet un signal électrique dont la fréquence est proportionnelle à la vitesse de rotation de la roue 5 et donc de la vitesse de défilement des cahiers, la fréquence du signal électrique émis par le détecteur inductif 8 étant également modifiée lorsque cette vitesse de défilement change.This device includes means for measuring the speed of scrolling of the sheet of notebooks C in the supply path vertical. These measurement means here consist of a mechanical sensor such as a wheel 5 carried by an arm 6 articulated on the chassis 3 using a spring 7 ensuring always a contact of wheel 5 with the sheet of notebooks scrolling and associated with an inductive sensor 8. The wheel 5 free in rotation is driven in rotation by the scroll C notebooks, therefore when the scrolling of notebooks C is disturbed, the speed of rotation of the wheel 5 indicator of the web speed is changed. The wheel 5 is symmetrically hollowed out and the inductive sensor emits an electrical signal, the frequency is proportional to the speed of rotation of the wheel 5 and therefore the running speed of the notebooks, the frequency of the electrical signal emitted by the inductive sensor 8 also being modified when this speed of scroll changes.

    L'information concernant la vitesse de rotation de la roue 5 mesurée est ensuite envoyée vers des moyens de comparaison de ladite vitesse avec la vitesse de défilement théorique des cahiers.Information concerning the speed of rotation of the wheel 5 measured is then sent to comparison means of said speed with the theoretical running speed of notebooks.

    Lorsqu'une vitesse de défilement des cahiers est détectée différente de la vitesse théorique elle révèle une accumulation de cahiers au point d'empilage ou bourrage B. En effet, lorsqu'un bourrage B survient, les cahiers C sont bloqués et s'accumulent les uns derrière les autres et le cahier C en contact avec les moyens de mesure de la vitesse n'avance plus. L'accumulation de cahiers C peut provoquer une surépaisseur incompatible avec le chemin défini entre les courroies intérieures 1 et les courroies extérieures 2 ce qui risque d'entraíner une détérioration et en particulier une sortie des courroies hors de leurs guides.When a scrolling speed of the notebooks is detected different from the theoretical speed it reveals a accumulation of notebooks at the stacking point or jam B. indeed, when jamming B occurs, notebooks C are blocked and build up one behind the other and the notebook C in contact with the speed measurement means no longer advance. The accumulation of C notebooks can cause excess thickness incompatible with the path defined between the internal belts 1 and external belts 2 which risk of causing deterioration and in particular release of the belts out of their guides.

    Aussi, dès que la vitesse de défilement est détectée comme révélant une accumulation de cahiers au point d'empilage P ou bourrage B par les moyens de comparaison (figure 2b), des moyens de commande associés sont mis en oeuvre pour actionner des moyens d'effacement au moins partiel du chemin d'amenée vertical des courroies extérieures. Ces moyens d'effacement sont dans l'exemple représenté constitués par des moyens d'entraínement en translation des courroies extérieures 2 en écartement de celles-ci par rapport à la table d'empilage T et à la cartouche en formation. C'est-à-dire que les moyens d'entraínement en translation écartent le châssis 3 portant les courroies 2 des cahiers reposant sur la table d'empilage T. Le châssis 3 présente au moins un bras 10 relié à un vérin pneumatique ou hydraulique 9 monté dans la tête d'empilage E.Also, as soon as the frame rate is detected as revealing an accumulation of notebooks at the stacking point P or stuffing B by the comparison means (FIG. 2b), associated control means are used to actuate means for at least partial erasure of the supply path vertical of the external belts. These means of erasure are in the example shown constituted by means drive in translation of the external belts 2 in spacing of the latter relative to the stacking table T and the cartridge in formation. That is to say that the means in translation drive away the chassis 3 bearing the belts 2 of the notebooks resting on the stacking table T. The chassis 3 has at least one arm 10 connected to a jack pneumatic or hydraulic 9 mounted in the stacking head E.

    Ainsi, le châssis 3 est entraíné en translation le long de la paroi verticale de la tête d'empilage E en écartement du point d'empilage P (selon la flèche A figure 2c) de telle sorte que les cahiers C bloqués sous forme d'un bourrage B échappent aux courroies extérieures 2 qui sont relevées (figure 2d) et lesdits cahiers C peuvent être entraínés par la table d'empilage T pour être évacués dudit point d'empilage P (figure 2e).Thus, the chassis 3 is driven in translation along the vertical wall of the stacking head E away from the stacking point P (according to arrow A in figure 2c) of such so that notebooks C blocked as a jam B escape the external belts 2 which are raised (Figure 2d) and said notebooks C can be driven by the stacking table T to be evacuated from said point stacking P (Figure 2e).

    Une fois que la vitesse de défilement est de nouveau détectée conforme à la vitesse de défilement théorique ou ayant atteint un seuil prédéterminé se rapprochant de la vitesse de défilement théorique, on déclenche de nouveau l'entraínement en translation du châssis 3 pour ramener celui-ci à sa position de fonctionnement c'est-à-dire en rapprochement du point d'empilage P (selon la flèche A' de la figure 2e) de sorte que les courroies 2 viennent en contact avec la partie supérieure des cahiers C juste après le point d'empilage contribuant ainsi à un bon empilement.Once the frame rate is detected again conforms to the theoretical running speed or having reaches a predetermined threshold approaching the speed of theoretical scrolling, we start training again in translation of the chassis 3 to bring it back to its operating position i.e. close to the stacking point P (according to arrow A 'in FIG. 2e) of so that the belts 2 come into contact with the part top of notebooks C just after the stacking point thus contributing to a good stacking.

    Un opérateur peut alors enlever les cahiers C du bourrage qui se trouvent dans la cartouche (figure 2f).An operator can then remove the notebooks C from the jam which are in the cartridge (figure 2f).

    L'invention offre donc un dispositif d'empilage pourvu d'un dispositif de détection et d'évacuation d'un bourrage de cahiers de manière simple, rapide et efficace.The invention therefore provides a stacking device provided with a device for detecting and removing a jam from notebooks simply, quickly and efficiently.
