Description

La présente invention concerne un dispositif de découpe automatisée de pains en tranches.The present invention relates to an automated cutting device sliced breads.

Des dispositifs de découpe automatisée de pains en tranches sont bien connus. On les rencontre dans la plupart des boulangeries artisanales et également en grandes surfaces. Ces dispositifs, ou trancheuses automatiques de pains selon l'état de la technique, fonctionnent selon le principe suivant : L'utilisateur du dispositif y introduit le pain qu'il désire couper en tranches en le plaçant dans un compartiment de chargement prévu à cet effet. Ce compartiment est traditionnellement disposé entre un élément d'entraînement du pain et un ensemble de lames parallèles destinées à trancher ledit pain. L'utilisateur met ensuite le dispositif en marche en enclenchant l'interrupteur prévu à cet effet, ce qui entraîne la mise en mouvement alternatif des lames et en mouvement de translation transversalement à la direction des lames de l'élément d'entraînement du pain. Le pain est dès lors déplacé par cet élément d'entraînement en direction des lames et la découpe commence lorsqu'il entre en contact avec ces dernières. L'utilisateur récupère son pain découpé en tranches dans un compartiment disposé de déchargement du côté des lames opposé à celui où est disposé le compartiment de chargement du pain dans le dispositif. Il ne reste plus alors à cet utilisateur qu'à emballer le pain découpé.Automated cutting devices for sliced breads are well known. They are found in most bakeries and also in supermarkets. These devices, or automatic bread slicers according to the state of the art, operate according to the following principle: The user of the device introduces the bread he wants to cut into slices by placing it in a loading compartment provided for this purpose . This compartment is traditionally arranged between a bread driving element and a set of parallel blades for slicing said bread. The user then starts the device by engaging the switch provided for this purpose, which causes the reciprocating movement of the blades and translational movement transversely to the direction of the blades of the drive element of the bread. The bread is then moved by this drive element towards the blades and cutting begins when it comes in contact with them. The user retrieves his sliced bread in a compartment disposed of unloading the side of the blades opposite to that where is placed the load compartment of the bread in the device. This user then only has to pack the cut bread.

Ce type de dispositif de découpe automatisée de pains en tranches selon l'état de la technique pose au moins deux problèmes. Le premier est qu'il requiert un mécanisme de déplacement de l'élément d'entraînement du pain relativement complexe en ce qu'il comprend un système de tringles, de guides et de propulsion qui a tendance lors de son fonctionnement de provoquer des vibrations importantes du bâti du dispositif. Le second problème posé par ce type de dispositif est qu'il requiert à la fois un premier compartiment de chargement du pain disposé d'un côté de l'ensemble des lames de découpe et un second compartiment distinct de déchargement du pain disposé de l'autre côté de l'ensemble de lames de découpe. Ceci entraîne une taille et donc un encombrement important du dispositif dû à la présence nécessaire de ces deux compartiments.This type of automated cutting device for sliced bread according to the state of the art poses at least two problems. The first is that it requires a movement mechanism of the relatively complex bread driving element in that it comprises a system of rods, guides and propulsion which tends during its operation to cause significant vibrations of the device frame. The second problem with this type of device is that it requires both a first bread loading compartment disposed on one side of all the cutting blades and a second separate bread unloading compartment disposed on the other side of the cutting blade assembly. This results in a size and therefore a large size of the device due to the necessary presence of these two compartments.

L'invention résout ces problèmes en fournissant un dispositif de découpe automatisée d'un pain en tranches comprenant un bâti, un compartiment de chargement du pain dans le dispositif, lequel compartiment comprend un premier élément de support du pain et un second élément de retenue du pain dans ce compartiment, le dispositif comprenant en outre un ensemble de lames de découpe du pain disposées sensiblement parallèlement les unes aux autres et agencées pour être animées d'un mouvement alternatif de va-et-vient, l'ensemble de lames étant monté dans un cadre mobile agencé pour être déplacé par un moyen de déplacement entre une première position dans laquelle le pain à découper peut être chargé dans le compartiment susmentionné et une seconde position dans laquelle le pain découpé par lesdites lames peut être extrait dudit compartiment.The invention solves these problems by providing an automated slice cake cutter comprising a frame, a bread loading compartment in the device, which compartment comprises a first bread support member and a second bread support member. bread in this compartment, the device further comprising a set of bread cutting blades arranged substantially parallel to each other and arranged to be reciprocated reciprocating movement, the set of blades being mounted in a movable frame arranged to be moved by a moving means between a first position in which the bread to be cut can be loaded into the above-mentioned compartment and a second position in which the bread cut by said blades can be extracted from said compartment.

Grâce au cadre mobile portant l'ensemble de lames selon l'invention et agencé pour être déplacé entre une première position dans laquelle le pain à découper peut être chargé dans le compartiment de chargement et une seconde position dans laquelle le pain découpé peut être extrait du compartiment, plus aucun élément d'entraînement du pain n'est nécessaire et le mécanisme de déplacement de cet élément qui y est associé selon l'état de la technique disparaît par conséquent également, ce qui évite notamment le problème de vibration du bâti susmentionné consécutif à l'action du mécanisme de déplacement en question.Thanks to the movable frame carrying the blade assembly according to the invention and arranged to be moved between a first position in which the bread to be cut can be loaded into the loading compartment and a second position in which the cut bread can be extracted from the compartment, no more drive element of the bread is necessary and the movement mechanism of this element which is associated therewith according to the state of the art therefore also disappears, which notably avoids the problem of vibration of the aforementioned frame consecutive to the action of the displacement mechanism in question.

D'autre part, comme selon l'invention c'est l'ensemble de lames qui est déplacé au travers du pain lors de l'opération de découpe et non le pain qui est poussé au travers de cet ensemble de lames comme dans le cas de dispositif de découpe automatisée selon l'état de la technique, un seul compartiment de chargement du pain est nécessaire. Le pain y demeure durant l'opération de découpe et peut en être retiré une fois cette opération terminée. Ceci permet de réduire considérablement l'encombrement d'u tel dispositif.On the other hand, as according to the invention it is the set of blades that is moved through the bread during the cutting operation. and not the bread that is pushed through this set of blades as in the case of automated cutting device according to the state of the art, a single bread loading compartment is necessary. The bread remains there during the cutting operation and can be removed once this operation is completed. This makes it possible to considerably reduce the size of such a device.

Des formes de réalisations particulières de l'inventions sont décrites dans les revendications dépendantes comprises dans le jeu de revendications du présent texte.Particular embodiments of the invention are described in the dependent claims included in the set of claims of this text.

L'invention va à présent être décrite plus en détails au moyen de deux exemples illustrant chacun un mode de réalisation non limitatif de la portée de cette invention et en référence aux figures 1 a à 1d, 2a à 2d et 3a à 3f jointes, représentant des vues schématiques en coupe verticale d'un dispositif selon ladite invention.The invention will now be described in more detail by means of two examples each illustrating a non-limiting embodiment of the scope of this invention and with reference to FIGS. 1a to 1d, 2a to 2d and 3a to 3f attached, representing schematic views in vertical section of a device according to said invention.

Les figures 1 a à 1 d ainsi que 2a à 2d et 3a à 3f représentent un dispositif 1 de découpe automatisée d'un pain 6 en tranches comprenant un bâti 2, un compartiment 3 de chargement du pain dans le dispositif, lequel compartiment 3 comprend un premier élément 3a de support du pain 6 ainsi que dans le cas des figures 1a à 1d et 2a à 2d un second élément 3b de retenue du pain 6 dans le compartiment 3 disposé d'un côté de ce dernier et dans le cas des figures 3a à 3f, deux tels seconds éléments 3b disposés de part et d'autre du compartiment 3. Le dispositif 1 comprend en outre un ensemble 4 de lames de découpe du pain 6 disposées sensiblement parallèlement les unes aux autres et agencées pour être animées d'un mouvement alternatif de va-et-vient. L'ensemble 4 de lames est monté dans un cadre 5 mobile relativement au bâti 2 et agencé pour être déplacé entre une première position A représentée aux figures 1 a, 1b, 2a, 2b, 3a et 3e dans laquelle le pain 6 à découper peut être chargé dans le compartiment 3 lorsqu'un clapet 7 donnant accès à ce compartiment est relevé et une seconde position B représentée aux figures 1 c, 1 d, 2c, 2d, 3c, 3d et 3f dans laquelle le pain 6 une fois découpé par ledit ensemble 4 de lames peut être retiré du compartiment 3, le clapet 7 étant alors à nouveau relevé, celui-ci demeurant pour des raisons de sécurité rabaissé durant l'opération de découpe du pain 6 pour isoler le compartiment 3 de l'utilisateur du dispositif durant cette opération. Il est à noter que le clapet 7 pourrait être disposé non pas sur le dessus du dispositif comme représenté dans les figures mais, dans le cas des modes de réalisation de l'invention illustrés aux figures 1 a à 1 d et 2a à 2d, du côté du dispositif opposé à l'élément de retenue du pain 6 3b. Les éléments de support 3a et de retenue 3b du pain 6 sont constitués d'une plaque d'un matériau rigide dans lequel sont pratiquées des fentes dans lesquelles les lames de l'ensemble de lames 4 peuvent être déplacées lors de l'opération de découpe du pain 6.FIGS. 1a to 1d and 2a to 2d and 3a to 3f show a device 1 for automated cutting of a sliced bread 6 comprising a frame 2, a compartment 3 for loading bread into the device, which compartment 3 comprises a first element 3a bread support 6 as well as in the case of Figures 1a to 1d and 2a to 2d a second element 3b retaining bread 6 in the compartment 3 disposed on one side of the latter and in the case of figures 3a to 3f, two such second elements 3b disposed on either side of the compartment 3. The device 1 further comprises an assembly 4 of bread cutting blades 6 arranged substantially parallel to each other and arranged to be driven by reciprocating back and forth. The assembly 4 of blades is mounted in a frame 5 movable relative to the frame 2 and arranged to be moved between a first position A shown in Figures 1a, 1b, 2a, 2b, 3a and 3e in which the bread 6 to be cut can to be loaded in the compartment 3 when a valve 7 giving access to this compartment is raised and a second position B shown in FIGS. 1c, 1d, 2c, 2d, 3c, 3d and 3f wherein the bread 6 once cut by said set of blades 4 can be removed from the compartment 3, the valve 7 then being raised again, the latter remaining for security reasons lowered during the bread cutting operation 6 to isolate the compartment 3 of the user of the device during this operation. It should be noted that the valve 7 could be arranged not on the top of the device as shown in the figures but, in the case of the embodiments of the invention illustrated in FIGS. 1a to 1d and 2a to 2d, of FIG. side of the device opposite the bread retaining member 6 3b. The support elements 3a and retaining 3b of the bread 6 consist of a plate of a rigid material in which are formed slots in which the blades of the blade assembly 4 can be moved during the cutting operation bread 6.

Le dispositif 1 illustré comprend encore un élément pousse pain 10 monté de manière pivotante sur le cadre 5, agencé en forme de peigne entre les dents duquel passent les lames de l'ensemble de lames 4 et muni d'un moyen résilient tel qu'un ressort (non illustré) disposé de telle sorte à ce que cet élément pousse pain 10 exerce une pression sur le pain 6 lors de sa découpe par l'ensemble de lames 4, de manière à éviter des soubresauts dudit pain 6 dans le compartiment 3 pendant ladite découpe.The device 1 illustrated further comprises a push-rod element 10 pivotally mounted on the frame 5, arranged in the form of a comb between the teeth of which the blades of the blade assembly 4 pass and provided with a resilient means such that a spring (not illustrated) arranged so that this element pushes bread 10 exerts pressure on the bread 6 during its cutting by the set of blades 4, so as to avoid jolts of said bread 6 in the compartment 3 during said cut.

Les figures 1 a à 1d illustrent un mode de réalisation de l'invention selon lequel le cadre 5 est monté de manière pivotante sur un premier axe 8a fixe relativement au bâti 2, pour être est déplacé entre sa première A et sa seconde B positions selon un mouvement de rotation et selon lequel mode de réalisation, le moyen de déplacement du cadre 5 est constitué d'un vérin hydraulique ou pneumatique 9a fixé au bâti 2. Lorsque le cadre 5 a atteint sa seconde B position et que le pain 6 découpé en tranches a été extrait du dispositif 1, ledit cadre 5 est ramené dans sa première A position avant qu'un autre pain 6 à découper ne puisse être introduit dans le compartiment 3 du dispositif 1.FIGS. 1a to 1d illustrate an embodiment of the invention according to which the frame 5 is pivotally mounted on a first fixed axis 8a relative to the frame 2, to be moved between its first A and its second B positions according to a rotational movement and according to which embodiment, the frame of the displacement means 5 consists of a hydraulic or pneumatic cylinder 9a fixed to the frame 2. When the frame 5 has reached its second B position and the bread 6 cut in slices was extracted from the device 1, said frame 5 is returned to its first A position before another bread 6 to be cut can be introduced into the compartment 3 of the device 1.

Les figures 2a à 2d illustrent quant à elles un autre mode de réalisation de l'invention selon lequel le cadre 5 est agencé pour glisser sur deux rails 8b fixes relativement au bâti 2, par exemple au moyen de roulettes (non représentées) circulant sur les rails 8b, pour être déplacé entre sa première A et sa seconde B positions selon un mouvement de translation. Selon ce mode de réalisation, le moyen de déplacement du cadre 5 est constitué d'un premier moteur 9b. Ce premier moteur 9b peut, comme représenté aux figures 2a à 2d être solidaire du cadre 5 ou au contraire pourrait également être fixé au bâti 2 et provoquer le déplacement du cadre 5 par exemple au moyen d'une crémaillère ou d'une courroie crantée reliant le premier moteur 9b au cadre 5 par tout système connu, tel que de roues dentées ou de poulies.Figures 2a to 2d illustrate another embodiment of the invention according to which the frame 5 is arranged to slide on two rails 8b fixed relative to the frame 2, for example by means of rollers (not shown) circulating on the rails 8b, to be moved between its first A and its second B positions in a translational movement. According to this embodiment, the means for moving the frame 5 consists of a first motor 9b. This first motor 9b can, as shown in Figures 2a to 2d be secured to the frame 5 or on the contrary could also be attached to the frame 2 and cause the displacement of the frame 5 for example by means of a rack or a toothed belt connecting the first motor 9b in the frame 5 by any known system, such as gears or pulleys.

Les figures 3a à 3f représentent une variante du mode de réalisation de l'invention représenté aux figures 1 a à 1 d, dans laquelle un pain 6 peut être introduit dans le compartiment 3 du dispositif 1 une fois que le cadre 5 a atteint sa seconde B position, sans qu'il faille pour ce faire ramener ledit cadre 5 dans une première A position différente de ladite seconde B position qu'il a atteint en fin de découpe du pain précédent, comme illustré aux figures 3e et 3f. Lorsque le pain 6 est découpé selon cette procédure et que le cadre 5 arrive dans sa position B représentée à la figure 3f, un autre pain 6 peut être à nouveau introduit dans le compartiment 3 du dispositif 1 ce qui implique que la position de fin de découpe B du pain précédent dans laquelle celui-ci découpé en tranche peut être extrait du dispositif 1 devient celle de début de découpe A représentée à la figure 3a dans laquelle un nouveau pain 6 à découper peut être chargé dans le dispositif 1. Cette variante de mode de réalisation de l'invention permet dès lors d'économiser du temps et de l'énergie d'alimentation du moteur 9a relativement au mode de réalisation représenté aux figures 1a à 1d. Une telle variante n'impose que la présence d'un élément de retenue 3b d'un pain 6 de part et d'autre du compartiment 3 de chargement de ce pain dans le dispositif 1, un ensemble de lames de découpe 4 dont chaque lame est à double tranchant ainsi que la position du clapet 7 d'ouverture et de fermeture du dispositif 1 sur le dessus de ce dernier.FIGS. 3a to 3f show a variant of the embodiment of the invention shown in FIGS. 1a to 1d, in which a roll 6 can be introduced into the compartment 3 of the device 1 once the frame 5 has reached its second B position, without it being necessary to bring back said frame 5 in a first A position different from said second B position reached at the end of cutting the previous bread, as shown in Figures 3e and 3f. When the bread 6 is cut according to this procedure and the frame 5 arrives at its position B shown in FIG. 3f, another bread 6 can be introduced again into the compartment 3 of the device 1, which implies that the end position of cut B of the previous bread in which the latter sliced can be extracted from the device 1 becomes the beginning of cutting A shown in Figure 3a in which a new bread 6 to be cut can be loaded into the device 1. This variant of Embodiment of the invention thus saves time and power supply of the engine 9a relative to the embodiment shown in Figures 1a to 1d. Such a variant imposes only the presence of a retaining element 3b of a bread 6 on either side of the compartment 3 for loading this bread into the device 1, a set of cutting blades 4 each blade is double-edged and the position of the valve 7 opening and closing of the device 1 on top of the latter.

Il est à souligner qu'une variante équivalente à celle décrite ci-dessus peut être envisagée de la forme de réalisation de l'invention illustrée aux figures 2a à 2d. L'homme du métier sur base des informations exposées ici pourra sans peine adapter cette forme de réalisation pour réaliser ladite variante.It should be noted that a variant equivalent to that described above may be considered of the embodiment of the invention illustrated in Figures 2a to 2d. Those skilled in the art based on the information presented here can easily adapt this embodiment to achieve said variant.

Selon les modes de réalisation de l'invention illustrés à la fois aux figures 1a à 1 d, 2a à 2d ainsi que 3a à 3f, un second moteur 11 présentant un axe rotatif (non illustré) est monté sur le cadre 5 et est agencé pour imprimer un mouvement de va-et-vient à l'ensemble de lames 4 au moyen d'une courroie 17 pouvant, via une première poulie (non représentée) montée sur l'axe rotatif du second moteur 11, entraîner une deuxième poulie 12 dans un mouvement de rotation autour d'un deuxième axe 13 solidaire du cadre 5, sur laquelle poulie 12 étant monté de manière pivotante autour d'un troisième axe 14 fixé à ladite poulie 12 et de façon excentrée relativement à celle-ci, une bielle 15 connectée de manière pivotante à l'ensemble de lames 4 par un quatrième axe 16 solidaire dudit ensemble 4 de lames.According to the embodiments of the invention illustrated in FIGS. 1a to 1d, 2a to 2d as well as 3a to 3f, a second motor 11 having a rotary axis (not shown) is mounted on the frame 5 and is arranged to print a reciprocating motion to the blade assembly 4 by means of a belt 17 which can, via a first pulley (not shown) mounted on the rotary shaft of the second motor 11, drive a second pulley 12 in a rotational movement about a second axis 13 integral with the frame 5, on which pulley 12 is pivotally mounted about a third axis 14 fixed to said pulley 12 and eccentrically relative thereto, a connecting rod 15 pivotally connected to the blade assembly 4 by a fourth axis 16 integral with said blade assembly 4.

Lors du fonctionnement d'un dispositif selon l'invention, le cadre 5 est d'abord disposé dans sa position A illustrée aux figures 1 a, 1 b, 2a, 2b, 3a, 3e. Un pain 6 à découper en tranches est introduit dans le dispositif une fois le clapet 7 relevé comme illustré aux figures 1 a, 2a, 3a et 3e. le clapet 7 est ensuite refermé et l'opération de découpe du pain est enclenchée par pression d'un bouton (non représenté) commandant l'alimentation en énergie des moyens de déplacement du cadre 5 et de l'ensemble de lames 4. Le cadre 5 est alors déplacé selon la direction de la flèche horizontale représentée aux figures 1 b, 2b, 3b et 3f de sorte à ce que l'ensemble 4 de lames découpe le pain 6, ce qui est réalisé lorsque le cadre 5 arrive dans sa position B illustrée aux figures 1 c, 2c et 3c. Le clapet 7 peut alors être relevé et le pain 6 découpé extrait du compartiment 3 ainsi que montré aux figures 1 d, 2d et 3d.When operating a device according to the invention, the frame 5 is first disposed in its position A illustrated in Figures 1a, 1b, 2a, 2b, 3a, 3e. A bread slice 6 is introduced into the device once the valve 7 raised as illustrated in Figures 1a, 2a, 3a and 3e. the valve 7 is then closed again and the operation of cutting the bread is engaged by pressing a button (not shown) controlling the energy supply of the moving means of the frame 5 and the set of blades 4. The frame 5 is then moved in the direction of the horizontal arrow shown in Figures 1b, 2b, 3b and 3f so that the set of 4 blades cut the bread 6, which is achieved when the frame 5 arrives in its position B illustrated in Figures 1c, 2c and 3c. The valve 7 can then be raised and the cut 6 bread extracted compartment 3 as shown in Figures 1d, 2d and 3d.

Il apparaît clairement de ce qui précède que l'invention, en éliminant la nécessité de la présence d'un élément d'entraînement d'un pain au travers de l'ensemble de lames d'un dispositif selon l'état de la technique offre le double avantage d'à la fois supprimer les nuisances en termes de vibration inhérentes à un tel élément d'entraînement lors de son fonctionnement telles qu'exposées plus haut et de permettre la réalisation d'un dispositif de découpe automatique de pains en tranches d'un encombrement bien plus limité que celui d'un dispositif selon l'état de la technique qui doit comprendre un compartiment de déchargement d'un pain découpé distinct de celui de chargement dudit pain à découper, contrairement au dispositif selon l'invention.It is clear from the above that the invention, by eliminating the need for the presence of a drive element of a bread through the blade assembly of a device according to the state of the art offers the dual advantage of both eliminating the nuisance in terms of vibration inherent in such a drive element during its operation as described above and to allow the realization of a device for automatically cutting slices of bread a much smaller footprint than that of a device according to the state of the art which must include a compartment for unloading a cut bread separate from that of loading said bread to be cut, unlike the device according to the invention.
