Description

L'invention concerne une trancheuse pour couper des pains successifs avec un ensemble de lames agencées sensiblement parallèlement les unes par rapport aux autres et destinées à découper un pain en tranches. Cette ensemble de lames coopère avec un poussoir pour pousser le pain à travers l'ensemble de lames lorsque le pain est posé entre l'ensemble de lames et le poussoir dans un compartiment de chargement. La trancheuse comprend une surface de réception pour au moins un pain à découper, une surface de transport et une surface de déchargement. La surface de transport pour le pain est mobile entre une position de réception permettant de déplacer un pain à découper de la surface de réception vers la surface de transport, et une position de livraison permettant de poser le pain, lorsque celui-ci se trouve sur la surface de transport, dans le compartiment de chargement en regard de l'ensemble de lames. Le pain découpé en tranches est récupéré, après son passage à travers l'ensemble de lames, sur la surface de déchargement qui est adjacente à l'ensemble de lames.The invention relates to a slicer for cutting successive breads with a set of blades arranged substantially parallel to each other and intended to cut a sliced bread. This blade assembly cooperates with a pusher to push the bread through the blade assembly when the bread is placed between the blade assembly and the pusher in a loading compartment. The slicer includes a receiving surface for at least one bread to be cut, a transport surface and an unloading surface. The transport surface for the bread is movable between a reception position making it possible to move a bread to be cut from the reception surface towards the transport surface, and a delivery position making it possible to place the bread, when the latter is on the transport surface, in the loading compartment opposite the blade assembly. The sliced bread is recovered, after passing through the blade assembly, on the unloading surface which is adjacent to the blade assembly.

Une telle trancheuse à pain est, par exemple, décrit dans le document NL 2015186 . Lors de l'utilisation de cette trancheuse, il faut toujours attendre la fin de la coupe d'un pain précédent avant d'introduire un pain consécutif. La trancheuse ne permet donc pas de découper des pains consécutifs qui sont introduits dans la machine l'un après l'autre et côte à côte.Such a bread slicer is, for example, described in the document NL 2015 186 . When using this slicer, always wait for the end of cutting a previous loaf before introducing a consecutive loaf. The slicer therefore does not make it possible to cut consecutive loaves which are introduced into the machine one after the other and side by side.

Un des buts essentiels de la présente invention est de présenter une trancheuse à pain compacte dans laquelle il est possible d'introduire des pains à couper les uns après les autres à une vitesse élevée et de couper un grand nombre de pains dans un temps réduit.One of the essential aims of the present invention is to present a compact bread slicer in which it is possible to introduce buns to be cut one after the other at a high speed and to cut a large number of loaves in a short time.

A cet effet, la trancheuse comprend un moyen d'arrêt qui est mobile entre une position rétractée dans laquelle un pain peut être déplacé de la surface de réception vers la surface de transport, et une position avancée dans laquelle le moyen d'arrêt empêche le déplacement d'un pain de la surface de réception vers la surface de transport.To this end, the slicer comprises a stop means which is movable between a retracted position in which a loaf can be moved from the receiving surface to the transport surface, and an advanced position in which the stop means prevents the movement of a loaf from the receiving surface to the transport surface.

Avantageusement, le moyen d'arrêt coopère avec des moyens de détection pour détecter la réception d'un pain sur la surface de transport, ces moyens de détection générant un signal pour déplacer le moyen d'arrêt vers sa position avancée lorsque la réception d'un pain sur la surface de transport est détectée.Advantageously, the stop means cooperates with detection means for detecting the reception of a loaf on the transport surface, these detection means generating a signal to move the stop means towards its advanced position when the reception of a loaf on the transport surface is detected.

Suivant une forme de réalisation avantageuse de la trancheuse, suivant l'invention, les moyens de détection comprennent un capteur de réception permettant de détecter la réception d'un pain sur la surface de transport afin de déplacer le moyen d'arrêt vers sa position avancée lorsque la réception d'un pain est détectée par le capteur de réception.According to an advantageous embodiment of the slicer, according to the invention, the detection means comprise a reception sensor making it possible to detect the reception of a loaf on the transport surface in order to move the stop means towards its advanced position when the reception of a bread is detected by the reception sensor.

Suivant une forme de réalisation intéressante de l'invention, les moyens de détection comprennent un capteur de présence pour détecter la présence d'un pain dans sa totalité sur la surface de transport. Lorsque le pain est présent dans sa totalité sur la surface de transport ce capteur de présence déclenche le déplacement de la surface de transport de la position de réception vers la position de livraison pour poser le pain dans le compartiment de chargement.According to an advantageous embodiment of the invention, the detection means comprise a presence sensor for detecting the presence of a bread in its entirety on the transport surface. When the bread is present in its entirety on the transport surface, this presence sensor triggers the movement of the transport surface from the receiving position to the delivery position to place the bread in the loading compartment.

Suivant une forme de réalisation particulièrement avantageuse de l'invention, les moyens de détection permettent de détecter la délivrance d'un pain dans le compartiment de chargement à partir de la surface de transport.According to a particularly advantageous embodiment of the invention, the detection means make it possible to detect the delivery of a loaf of bread into the loading compartment from the transport surface.

Suivant une forme de réalisation particulière de l'invention, les moyens de détection comprennent un capteur de livraison pour détecter la délivrance d'un pain dans le compartiment de chargement à partir de la surface de transport. Ce capteur de livraison déclenche le déplacement de la surface de transport de la position de livraison vers la position de réception après la délivrance du pain à couper dans le compartiment de chargement.According to a particular embodiment of the invention, the detection means comprise a delivery sensor for detecting the delivery of a loaf in the loading compartment from the transport surface. This delivery sensor triggers the movement of the transport surface from the delivery position to the reception position after the delivery of the bread to be cut into the loading compartment.

De préférence, le capteur de de réception constitue également le capteur de livraison.Preferably, the reception sensor also constitutes the delivery sensor.

L'invention concerne également un procédé pour couper des pains successifs en tranches, dans lequel des pains à couper sont posés successivement sur une surface de réception et sont déplacés les uns après les autres de la surface de réception vers une surface de transport qui est dans une position de réception, la surface de transport étant déplacée vers une position de livraison après chaque réception d'un pain à couper, le pain qui se trouve sur la surface de transport est ensuite déplacé vers un compartiment de chargement, ce pain étant alors poussé à travers un ensemble de lames pour le couper en tranches et la surface de transport est retournée vers la position de réception pour recevoir un pain successif.The invention also relates to a method for cutting successive loaves into slices, in which loaves to be cut are placed successively on a receiving surface and are moved one after the other from the receiving surface to a transport surface which is in a receiving position, the transport surface being moved to a delivery position after each reception of a bread to be cut, the bread which is on the transport surface is then moved to a loading compartment, this bread being then pushed through a set of blades to cut it into slices and the transport surface is returned to the receiving position to receive a successive bread.

Ce procédé est caractérisé en ce que, lors de la réception d'un pain sur la surface de transport lorsque celle-ci est dans sa position de réception, un moyen d'arrêt est entrainé d'une position rétractée vers une position avancée de sorte que ce moyen d'arrêt s'étend dans cette position avancée en aval d'un pain successif pour empêcher le déplacement de ce pain successif vers la surface de transport. Lorsque le pain à couper est dans sa totalité présent sur la surface de transport, cette surface est déplacée vers la position de livraison pour déplacer le pain à couper vers le compartiment de chargement, et, après que le pain à couper a quitté la surface de transport, celle-ci est retournée vers la position de réception et le moyen d'arrêt est déplacé vers sa position rétractée afin de recevoir le pain successif sur la surface de transport.This method is characterized in that, when a loaf is received on the transport surface when the latter is in its receiving position, a stop means is driven from a retracted position to an advanced position so that this stop means extends in this advanced position downstream of a successive loaf to prevent the displacement of this successive loaf towards the transport surface. When the bread to be cut is entirely present on the transport surface, this surface is moved to the delivery position to move the bread to be cut towards the loading compartment, and, after the bread to be cut has left the surface of transport, it is returned to the receiving position and the stop means is moved to its retracted position in order to receive the successive bread on the transport surface.

Dans les différentes figures les mêmes chiffres de référence se rapportent aux mêmes éléments ou à des éléments analogues.In the various figures, the same reference numerals relate to the same or similar elements.

D'une façon générale la présente invention est relative à une machine pour couper des pains en tranches comme représentée dans les figures. Une telle trancheuse de pain comprend un bâti 1 dans lequel il est prévu un ensemble de lames 2 présentant des lames 3 agencées sensiblement parallèlement les unes par rapport aux autres. Ces lames 3 sont soumises à un mouvement de va-et-vient suivant leur direction longitudinale pour permettre de couper un pain en tranches qui est poussé à travers cet ensemble de lames 2.In general, the present invention relates to a machine for cutting bread into slices as shown in the figures. Such a bread slicer comprises a frame 1 in which there is provided a set of blades 2 having blades 3 arranged substantially parallel to each other. These blades 3 are subjected to a back-and-forth movement in their longitudinal direction to make it possible to cut a sliced bread which is pushed through this set of blades 2.

Une surface de réception 4 sur laquelle les pains à couper sont posés pour être introduits dans la trancheuse est prévu à la partie supérieure de la trancheuse, comme montré dans la figure 1. Cette surface de réception 4 est suivie d'une surface de transport 5. Entre la surface de réception 4 et la surface de transport 5, un moyen d'arrêt 6 est monté.A receiving surface 4 on which the loaves to be cut are placed to be introduced into the slicer is provided at the upper part of the slicer, as shown in the figure 1 . This receiving surface 4 is followed by a transport surface 5. Between the reception surface 4 and the transport surface 5, a stop means 6 is mounted.

La surface de transport 5 est mobile entre une position de réception, comme représentée dans les figures 2 à 4, et une position de livraison, comme représentée dans les figures 5 et 6.The transport surface 5 is movable between a receiving position, as shown in the figures 2 to 4 , and a delivery position, as shown in Figures 5 and 6 .

Ainsi, la surface de transport 5 permet de déplacer un pain à couper de la surface de réception 4 vers un compartiment de chargement 7. Ce compartiment de chargement 7 est adjacent à l'ensemble de lames 2 et comprend un poussoir 8 qui permet de pousser un pain à travers l'ensemble de lames 2 pour le couper en tranches. Le compartiment de chargement 7 est de préférence localisé en dessous de la surface de réception 4 et de la surface de transport 5 lorsque cette dernière est dans la position de réception.Thus, the transport surface 5 makes it possible to move a bread to be cut from the reception surface 4 to a loading compartment 7. This loading compartment 7 is adjacent to the blade assembly 2 and comprises a pusher 8 which makes it possible to push a loaf through the blade assembly 2 to cut it into slices. The loading compartment 7 is preferably located below the receiving surface 4 and the transport surface 5 when the latter is in the receiving position.

Lorsque le pain est poussé à travers l'ensemble de lames 2, pendant que les lames 3 sont soumises à un mouvement de va-et-vient suivant leur direction longitudinale, il est coupé en tranches et déplacé vers une surface de déchargement 9. Le pain coupé en tranches peut ainsi être récupéré de la surface de déchargement 9 par un opérateur pour être ensaché. La surface de déchargement 9 est donc adjacente à l'ensemble de lames 2 au côté qui opposé au compartiment de chargement 7.When the bread is pushed through the blade assembly 2, while the blades 3 are subjected to a back and forth movement in their direction longitudinal, it is cut into slices and moved to an unloading surface 9. The bread cut into slices can thus be recovered from the unloading surface 9 by an operator to be bagged. The unloading surface 9 is therefore adjacent to the blade assembly 2 on the side opposite the loading compartment 7.

Pour couper des pains successifs en tranches, les pains sont posés l'un après l'autre sur la surface de réception 4, comme montré dans la figure 2. La surface de réception 4 est inclinée de sorte qu'un pain qui est posé sur la surface de réception se déplace automatiquement vers la surface de transport 5. En effet, les pains 10 et 11 se déplacent côte à côte vers la surface de transport 5. Dans la position de réception de la surface de transport 5, cette surface s'étend dans le prolongement de la surface de réception 4 du côté bas de la surface de réception 4 de sorte qu'un pain 10 qui est posé sur la surface de réception 4 se déplace automatiquement, par exemple, sous l'influence de la gravité vers la surface de transport 5.To cut successive breads into slices, the breads are placed one after the other on the receiving surface 4, as shown in the figure 2 . The receiving surface 4 is inclined so that a loaf which is placed on the receiving surface automatically moves towards the transport surface 5. In fact, the loaves 10 and 11 move side by side towards the transport surface 5 In the reception position of the transport surface 5, this surface extends in the extension of the reception surface 4 on the bottom side of the reception surface 4 so that a loaf 10 which is placed on the surface of reception 4 moves automatically, for example, under the influence of gravity towards the transport surface 5.

Afin de permettre le déplacement des pains sur les surfaces de réception et de transport 4 et 5, celles-ci présentent, avantageusement, un tapis roulant, une succession de rouleaux à rotation libre ou un surface lisse à friction réduite. Dans la forme de réalisation de l'invention représentée dans les figures, les surfaces de réception et de transport 4 et 5 sont pourvues d'une succession de rouleaux 12 qui peuvent tourner librement autour de leur axe.In order to allow the movement of the loaves on the reception and transport surfaces 4 and 5, these advantageously have a conveyor belt, a succession of rollers with free rotation or a smooth surface with reduced friction. In the embodiment of the invention shown in the figures, the receiving and transport surfaces 4 and 5 are provided with a succession of rollers 12 which can rotate freely around their axis.

Comme déjà mentionné ci-dessus, un moyen d'arrêt 6 est prévu entre la surface de réception 4 et la surface de transport 5. Ce moyen d'arrêt 6 est, en particulier, prévu au bord bas de la surface de réception 4 qui s'étend du côté de la surface de transport 5. Ce moyen d'arrêt 6 est mobile entre une position rétractée, comme représentée dans la figure 2, dans laquelle un pain 10 ou 11 peut être déplacé de la surface de réception 4 vers la surface de transport 5 et une position avancée, comme représentée dans la figure 4, dans laquelle le moyen d'arrêt 6 empêche le déplacement d'un pain 11 de la surface de réception 4 vers la surface de transport 5.As already mentioned above, a stop means 6 is provided between the reception surface 4 and the transport surface 5. This stop means 6 is, in particular, provided at the bottom edge of the reception surface 4 which extends from the side of the transport surface 5. This stop means 6 is movable between a retracted position, as shown in the figure 2 , in which a loaf 10 or 11 can be moved from the receiving surface 4 to the transport surface 5 and an advanced position, as shown in the figure 4 , in which the stop means 6 prevents the movement of a loaf 11 from the receiving surface 4 towards the transport surface 5.

Le moyen d'arrêt 6 s'étend, de préférence, dans le plan de la surface de réception 4 ou en dessous de cette surface 4 dans la position rétractée du moyen d'arrêt 6 afin de permettre le passage d'un pain. Dans la position avancée, ce moyen d'arrêt est, préférentiellement, élevé par rapport à cette surface 4 dans sa position avancée pour arrêter le déplacement des pains. Dans la forme de réalisation de l'invention, représentée dans les figures, le moyen d'arrêt 6 comprend un bar qui s'étend transversalement par rapport à la direction de déplacement des pains 10 et 11 ou qui est parallèle aux rouleaux 12. Dans certains cas, le moyen d'arrêt peut comprendre l'un des rouleaux 12 qui est alors monté de manière à pouvant être rétracté et avancé par rapport au plan de la surface de réception 4. Il est par exemple possible que le moyen d'arrêt 6 est constitué d'une plaque oblongue articulée qui s'étend dans le plan de la surface de réception 4 dans la position rétractée et qui s'étend transversalement par rapport à ce plan dans la position avancée.The stop means 6 preferably extends in the plane of the receiving surface 4 or below this surface 4 in the retracted position of the stop means 6 in order to allow the passage of a loaf. In the advanced position, this stop means is preferably raised relative to this surface 4 in its advanced position to stop the movement of the loaves. In the embodiment of the invention, shown in the figures, the stop means 6 comprises a bar which extends transversely to the direction of movement of the loaves 10 and 11 or which is parallel to the rollers 12. In some cases, the means d 'stop may include one of the rollers 12 which is then mounted so as to be retractable and advanced relative to the plane of the receiving surface 4. It is for example possible that the stop means 6 consists of a articulated oblong plate which extends in the plane of the receiving surface 4 in the retracted position and which extends transversely with respect to this plane in the advanced position.

Le moyen d'arrêt 6 coopère avec des moyens de détection pour détecter la réception d'un pain sur la surface de transport 5. Lorsque un pain 10 à couper se déplace de la surface de réception 4 vers la surface de transport 5, la présence de ce pain 10 sur la surface de transport 5 est détectée par ces moyens de détection qui génèrent un signal pour déplacer le moyen d'arrêt 6 vers sa position avancée pour arrêter le pain successif 11.The stop means 6 cooperates with detection means for detecting the reception of a loaf on the transport surface 5. When a loaf 10 to be cut moves from the reception surface 4 to the transport surface 5, the presence of this bread 10 on the transport surface 5 is detected by these detection means which generate a signal to move the stop means 6 to its advanced position to stop the successive bread 11.

De préférence, les moyens de détection comprennent un capteur de réception 13 qui permet de détecter la réception d'un pain 10 sur la surface de transport afin de déplacer le moyen d'arrêt 6 vers sa position avancée au moment de la détection d'un pain 10 par ce capteur de réception 13, comme représenté dans la figure 3. Ce capteur de réception 13 comprend, par exemple, un œil optique.Preferably, the detection means comprise a reception sensor 13 which makes it possible to detect the reception of a loaf 10 on the transport surface in order to move the stop means 6 to its advanced position at the time of detection of a bread 10 by this reception sensor 13, as shown in the figure 3 . This reception sensor 13 comprises, for example, an optical eye.

Dans la forme de réalisation de l'invention, représentée dans les figures 2 à 7, la présence du pain 10 sur la surface de transport est détecté avant que le pain 10 a quitté complètement la surface de réception 4. Ainsi, le moyen d'arrêt 6 est déplacé vers sa position avancée lorsque le pain 10 à couper est en regard du moyen d'arrêt 6, comme représenté dans la figure 3. Ceci garantit que le moyen d'arrêt 6 est dans sa position avancée avant que le pain 11 successif arrive à l'endroit de ce moyen d'arrêt 6 de sorte que le déplacement de ce pain 11 successif est arrêté. Ceci est surtout important lorsque les pains sont déplacé côte à côte sur la surface de réception 4.In the embodiment of the invention, shown in figures 2 to 7 , the presence of the bread 10 on the transport surface is detected before the bread 10 has completely left the receiving surface 4. Thus, the stop means 6 is moved to its advanced position when the bread 10 to be cut is opposite stop means 6, as shown in the figure 3 . This guarantees that the stop means 6 is in its advanced position before the successive loaf 11 arrives at the location of this stop means 6 so that the movement of this successive loaf 11 is stopped. This is especially important when the loaves are moved side by side on the receiving surface 4.

Le pain 10 à couper se déplace donc jusqu'à ce qu'il se trouve complètement sur la surface de transport 5 pendant que le pain successif 11 est arrêté par le moyen d'arrêt 6, comme représenté dans la figure 4. La surface de transport 5 est ensuite déplacée vers sa position de livraison, comme représenté dans la figure 5 pour permettre que le pain 10 se déplace vers le compartiment de chargement 7.The bread 10 to be cut therefore moves until it is completely on the transport surface 5 while the successive bread 11 is stopped by the stop means 6, as shown in the figure 4 . The transport surface 5 is then moved to its delivery position, as shown in the figure 5 to allow the bread 10 to move towards the loading compartment 7.

La surface de transport 5 est dans cette position de livraison inclinée vers le fond du compartiment de chargement 7 de sorte que le pain 10 se déplace automatiquement vers ce compartiment de chargement 7.The transport surface 5 is in this delivery position inclined towards the bottom of the loading compartment 7 so that the bread 10 automatically moves towards this loading compartment 7.

Suivant une forme de réalisation intéressante de l'invention, les moyens de détection comprennent également un capteur de présence 14 pour détecter la présence du pain 10 dans sa totalité sur la surface de transport 5. Ce capteur 14 comprend, par exemple, un œil optique qui est prévu à une distance du bord libre 15 de la surface de transport 5 qui est plus grand que la largeur d'un pain dans la direction du déplacement des pains. Le bord libre 15 de la surface de transport 5 s'étend, en particulier, au côté de la surface de réception 4 lorsque la surface de transport 5 est dans sa position de réception.According to an advantageous embodiment of the invention, the detection means also comprise a presence sensor 14 for detecting the presence of the bread 10 in its entirety on the transport surface 5. This sensor 14 comprises, for example, an optical eye which is provided at a distance from the free edge 15 of the transport surface 5 which is greater than the width of a loaf in the direction of movement of the loaves. The free edge 15 of the transport surface 5 extends, in particular, to the side of the reception surface 4 when the transport surface 5 is in its reception position.

Suivant une autre forme de réalisation, le capteur de présence 14 comprend un capteur de contact qui est prévu à une butée d'arrêt 16 présent à l'extrémité de la surface de transport 5 opposée au bord libre 15. La distance entre le bord libre 15 et cette butée d'arrêt est normalement supérieure à la largeur d'un pain dans la direction de déplacement des pains 10 et 11.According to another embodiment, the presence sensor 14 comprises a contact sensor which is provided with a stopper 16 present at the end of the transport surface 5 opposite the free edge 15. The distance between the free edge 15 and this stop is normally greater than the width of a loaf in the direction of movement of the loaves 10 and 11.

Ainsi, la présence de ce capteur de présence 14 garantit que le pain 10 à couper est entièrement présent sur la surface de transport 5 et a quitté complètement la surface de réception 4 avant que la surface de transport 5 soit déplacée vers la position de livraison comme représenté dans la figure 5.Thus, the presence of this presence sensor 14 guarantees that the bread 10 to be cut is entirely present on the transport surface 5 and has completely left the reception surface 4 before the transport surface 5 is moved to the delivery position as depicted in the figure 5 .

Lors du déplacement de la surface de transport 5 vers sa position de livraison, le bord libre 15 est descendu vers le fond du compartiment de chargement 7 et le pain 10 à couper se déplace, par exemple sous l'action de la gravité, à travers le bord libre 15 vers le compartiment de chargement 7, comme indiqué dans la figure 6.When the transport surface 5 moves to its delivery position, the free edge 15 is lowered towards the bottom of the loading compartment 7 and the bread 10 to be cut moves, for example under the action of gravity, through the free edge 15 towards the loading compartment 7, as indicated in the figure 6 .

Les moyens de détection permettent éventuellement également de détecter si le pain 10 a quitté la surface de transport 5 et donc si le pain 10 a été délivré dans le compartiment de chargement 7 à partir de la surface de transport 5.The detection means possibly also make it possible to detect if the bread 10 has left the transport surface 5 and therefore if the bread 10 has been delivered to the loading compartment 7 from the transport surface 5.

A cet effet, les moyens de détection comprennent, par exemple, un capteur de livraison 17 pour détecter la délivrance d'un pain 10 dans le compartiment de chargement 7 à partir de la surface de transport 5. Ce capteur de livraison 17 permet de déclencher le déplacement de la surface de transport 5 de la position de livraison vers la position de réception lorsqu'il est détecté que le pain 10 est délivré dans le compartiment de chargement 7. Le détecteur de délivrance 17 comprend, par exemple, un œil optique qui est positionné en regard du bord libre 15 de la surface de transport 5.To this end, the detection means comprise, for example, a delivery sensor 17 for detecting the delivery of a loaf 10 into the loading compartment 7 from the transport surface 5. This delivery sensor 17 makes it possible to trigger movement of the transport surface 5 from the delivery position to the reception position when it is detected that the bread 10 is delivered into the loading compartment 7. The delivery detector 17 comprises, for example, an optical eye which is positioned opposite the free edge 15 of the transport surface 5.

Il est également possible que le capteur de réception 13 constitue également le capteur de livraison 17. Dans un tel cas, le capteur de réception 13 est, par exemple, positionné au-dessus de la surface de transport 5 dans une position qui permet de détecter la réception d'un pain par la surface de transport 5, lorsque cette dernière est dans la position de réception, et qui permet de surveiller l'endroit du bord libre 15 de la surface de transport 5 lorsque celle-ci est dans la position de livraison.It is also possible that the reception sensor 13 also constitutes the delivery sensor 17. In such a case, the reception sensor 13 is, for example, positioned above the transport surface 5 in a position which makes it possible to detect the reception of a loaf by the transport surface 5, when the latter is in the reception position, and which makes it possible to monitor the location of the free edge 15 of the transport surface 5 when the latter is in the position of delivery.

Il est également possible que le capteur de réception 13 est monté de manière fixe par rapport à la surface de transport 5 de sorte que le capteur est déplacé ensemble avec cette surface. Dans la position de livraison de la surface de transport 5, le capteur de réception 13 constitue alors un capteur de livraison.It is also possible that the reception sensor 13 is fixedly mounted relative to the transport surface 5 so that the sensor is moved together with this surface. In the delivery position of the transport surface 5, the reception sensor 13 then constitutes a delivery sensor.

Après que le pain 10 à couper est introduit dans le compartiment de chargement 7, comme représenté dans la figure 7, la surface de transport 5 est retournée de la position de livraison vers la position de réception et le poussoir 8 est déplacé vers le pain 10 afin de pousser celui-ci à travers l'ensemble des lames 2.After the bread 10 to be cut is introduced into the loading compartment 7, as shown in the figure 7 , the transport surface 5 is returned from the delivery position to the reception position and the pusher 8 is moved towards the bread 10 in order to push the latter through the assembly of blades 2.

Lorsque la surface de transport 5 est arrivée dans la position de réception, le moyen d'arrêt 6 est déplacé vers la position rétractée, comme représenté dans la figure 2, pour permettre de déplacer le pain suivant 11 vers la surface de transport 5.When the transport surface 5 has arrived in the receiving position, the stop means 6 is moved to the retracted position, as shown in the figure 2 , to allow the next loaf 11 to be moved towards the transport surface 5.

La surface de transport 5 est de préférence monté de manière pivotante et présente, par exemple, un axe d'articulation à l'endroit de la butée d'arrêt 16.The transport surface 5 is preferably pivotally mounted and has, for example, a hinge pin at the location of the stopper 16.

Le poussoir 8 est accommodé dans le compartiment de chargement 7 et en dessous de la surface de transport 5. Lorsque la surface de transport 5 est dans la position de livraison, le poussoir 8 est, de préférence, situé en dessous de l'endroit où la surface de transport 5 présente un axe d'articulation 18. Ainsi, il est assuré que le pain 10 est toujours posé par la surface de transport 5 entre l'ensemble de lames 2 et le poussoir 8 dans le compartiment de chargement 7.The pusher 8 is accommodated in the loading compartment 7 and below the transport surface 5. When the transport surface 5 is in the delivery position, the pusher 8 is preferably located below where the transport surface 5 has a hinge axis 18. Thus, it is ensured that the bread 10 is always placed by the transport surface 5 between the blade assembly 2 and the pusher 8 in the loading compartment 7.

De préférence, les pains à couper sont déplacés le long des surfaces de réception et de transport grâce à l'action de la gravité, mais il est également possible que les pains sont déplacés par moyens d'un entraîneur ou que les surfaces 4 et 5 présentent des moyens d'entraînement comme par exemple un tapis roulant entraîné ou des rouleaux successifs entraînés.Preferably, the loaves to be cut are moved along the receiving and transport surfaces by the action of gravity, but it is also it is possible that the loaves are moved by means of a coach or that the surfaces 4 and 5 have drive means such as for example a driven treadmill or successive driven rollers.

Il est bien entendu que l'invention n'est pas limitée aux différentes formes de réalisation décrites ci-dessus, mais que d'autres variantes encore peuvent être envisagées sans sortir du cadre de la présente invention, notamment en ce qui concerne les moyens de détection et les types de capteurs utilisés, ainsi que de la constitution des surfaces de réception et de transport.It is understood that the invention is not limited to the various embodiments described above, but that still other variants can be envisaged without departing from the scope of the present invention, in particular as regards the means of detection and the types of sensors used, as well as the constitution of the reception and transport surfaces.

Il est, par exemple, possible que le détecteur de réception 13 détecte la réception d'un pain sur la surface de transport 5 et détecte également la fin du pain qui passe devant ce capteur. Ainsi, le capteur de réception détecte également la présence du pain dans sa totalité sur la surface de transport. Par conséquent, le capteur de réception peut générer un signal pour déplacer la surface de transport 5 vers la position de livraison lorsqu'il a détecté que le pain a passé complètement devant ce capteur.It is, for example, possible that the reception detector 13 detects the reception of a loaf of bread on the transport surface 5 and also detects the end of the loaf which passes in front of this sensor. Thus, the reception sensor also detects the presence of the whole bread on the transport surface. Consequently, the reception sensor can generate a signal to move the transport surface 5 to the delivery position when it has detected that the bread has passed completely past this sensor.
