Description

L'invention concerne une trancheuse pour couper un pain en tranches. Cette trancheuse comprend un compartiment de chargement pour poser un pain à couper qui est connecté à un compartiment de réception, d'où le pain coupé en tranches peut être récupéré.The invention relates to a slicer for cutting bread into slices. This slicer includes a loading compartment for placing a loaf to be cut which is connected to a receiving compartment, from where the sliced bread can be retrieved.

Un poussoir permet de déplacer le pain entre le compartiment de chargement et le compartiment de réception suivant une direction de déplacement du pain. Ce poussoir.A pusher makes it possible to move the bread between the loading compartment and the receiving compartment following a direction of movement of the bread. This pusher.

Pour couper des tranches successives du pain lorsque celui-ci est déplacé du compartiment de chargement vers le compartiment de réception suivant ladite direction de déplacement du pain, une lame de coupe est prévue. Cette lame de coupe peut être déplacée suivant un plan de coupe s'étendant entre le compartiment de chargement et le compartiment de réception et sensiblement perpendiculairement par rapport à ladite direction de déplacement du pain.To cut successive slices of bread when it is moved from the loading compartment to the receiving compartment following said direction of movement of the bread, a cutting blade is provided. This cutting blade can be moved along a cutting plane extending between the loading compartment and the receiving compartment and substantially perpendicular to said direction of movement of the bread.

La trancheuse comprend également un support de tranches qui s'étend dans le compartiment de réception et qui est destiné à exercer une force de pression contre la partie déjà coupée du pain pour maintenir les tranches du pain l'une contre l'autre. Ce support de tranches est mobile et peut se déplacer autour d'un axe de pivot pour maintenir le support en contact avec la partie du pain coupée au fur et à mesure que cette partie coupée avance dans le compartiment de réception.The slicer also includes a slice support which extends into the receiving compartment and which is intended to exert a pressing force against the already cut portion of the bread to hold the slices of the bread against each other. This slice support is movable and can move around a pivot axis to keep the support in contact with the cut part of the bread as this cut part advances into the receiving compartment.

Ce support de tranches coopère avec un ressort à lames présentant une lame qui exerce une force de poussée sur le support de tranches afin de maintenir ce support en appui contre la partie du pain coupée.This slice support cooperates with a leaf spring having a blade which exerts a pushing force on the slice support in order to keep this support resting against the cut part of the bread.

Des trancheuses de pain existantes présentant un support de tranches qui est entrainé par un ressort ou par gravité, sont décrites dans les documents DE 4010407 A1 , DE 8904726 U1 , DE 102008012885 , DE 102010015367 , DE 102010036721 , DE 102010047585 , DE 202012009223 U1 , DE 202017002742 U1 ou EP 2368678 B1 .Existing bread slicers having a slice support which is driven by a spring or by gravity are described in the documents DE 4010407 A1 , DE 8904726 U1 , DE 102008012885 , DE 102010015367 , DE 102010036721 , DE 102010047585 , DE 202012009223 U1 , FROM 202017002742 U1 Or EP 2368678 B1 .

Ce trancheuses existantes présentent l'inconvénient qu'il est impossible ou difficile de modifier la force de poussée qui est exercée par le support de tranches sur la partie du pain coupée. Dans certaines machines il est possible de régler cette force de poussée après l'ouverture ou le démontage du bâti de la trancheuse. De plus, dans les trancheuses existantes la force de poussée exercée par le support de tranches sur le pain augmente au fur au fur et à mesure que le support se déplace lors de l'avancement des tranches du pain coupé.These existing slicers have the disadvantage that it is impossible or difficult to modify the thrust force which is exerted by the slice support on the part of the cut bread. In some machines it is possible to adjust this pushing force after opening or disassembling the slicer frame. Furthermore, in existing slicers the thrust force exerted by the slice support on the bread increases as the support moves during the advancement of the slices of the cut bread.

Le but de l'invention est, par conséquent, de proposer une trancheuse qui permet de régler la force de pression exercée par le support de tranches de manière très simple sans qu'il soit nécessaire d'ouvrir le bâti de la trancheuse. L'invention veut également proposer un trancheuse avec un support de tranches dont la force de poussée qui est exercée est sensiblement indépendante du déplacement de ce support.The aim of the invention is, therefore, to provide a slicer which makes it possible to adjust the pressure force exerted by the slice support in a very simple manner without it being necessary to open the slicer frame. The invention also aims to propose a slicer with a slice support whose thrust force which is exerted is substantially independent of the movement of this support.

A cet effet, un système de réglage est prévu qui permet de modifier la position de l'une des extrémités de la lame du ressort à lame par rapport au bâti de la trancheuse pour régler ladite force de poussée. Ce système de réglage comprend un élément rotatif qui peut être entrainé autour d'un axe et des moyens de transformation de mouvement pour transformer un mouvement rotatif de l'élément rotatif en un mouvement de translation de ladite extrémité de la lame par rapport au bâti.For this purpose, an adjustment system is provided which makes it possible to modify the position of one of the ends of the blade of the leaf spring relative to the frame of the slicer to adjust said pushing force. This adjustment system comprises a rotary element which can be driven around an axis and movement transformation means for transforming a rotary movement of the rotary element into a translation movement of said end of the blade relative to the frame.

Avantageusement, l'élément rotatif est accessible à partir de l'extérieur du bâti de la trancheuse pour permettre d'entrainer cet élément rotatif autour dudit axe pour régler ladite force de poussée exercée par le support de tranches sur la partie du pain coupée.Advantageously, the rotating element is accessible from the outside of the frame of the slicer to enable this rotating element to be driven around said axis to adjust said thrust force exerted by the slice support on the part of the cut bread.

De préférence, l'élément rotatif du système de réglage comprend une vis agissant sur ladite extrémité de la lame et coopérant avec un écrou fixé par rapport au bâti ou par rapport ladite extrémité, de sorte que, lorsque la vis est tournée par rapport à l'écrou, le mouvement rotatif de la vis est transformé en un mouvement de translation ladite extrémité.Preferably, the rotating element of the adjustment system comprises a screw acting on said end of the blade and cooperating with a nut fixed relative to the frame or relative to said end, so that, when the screw is rotated relative to the nut, the rotary movement of the screw is transformed into a translation movement at said end.

Suivant une forme de réalisation intéressante de la trancheuse, suivant l'invention, ladite lame est repliée sur elle-même pour former une boucle, cette boucle étant en contact avec le support de tranches en exerçant une force de pression contre ce support de tranches pour le maintenir en contact avec la partie du pain coupé en tranchesAccording to an interesting embodiment of the slicer, according to the invention, said blade is folded on itself to form a loop, this loop being in contact with the slice support by exerting a pressure force against this slice support to keep it in contact with the sliced part of the bread

Dans les différentes figures, les mêmes chiffres de référence concernent des éléments analogues ou identiques.In the different figures, the same reference numbers relate to similar or identical elements.

L'invention concerne en générale une trancheuse pour couper un pain en tranches. La figure 1 montre un exemple d'une trancheuse 1. Cette trancheuse 1 comprend un bâti 2 qui forme un volume fermé dans lequel sont prévus, entre-autres, un moteur pour une lame circulaire, un entraînement, une commande électrique et d'autres pièces de la machine qui doivent être inaccessibles aux utilisateurs.The invention generally relates to a slicer for cutting bread into slices. There figure 1 shows an example of a slicer 1. This slicer 1 comprises a frame 2 which forms a closed volume in which are provided, among other things, a motor for a circular blade, a drive, an electrical control and other parts of the machine which must be inaccessible to users.

Pour couper un pain en tranches, celui-ci est placé sur le fond d'un compartiment de chargement 3 de la trancheuse. Ce compartiment de chargement 3 est connecté à un compartiment de réception 4 d'où le pain peut être récupéré après sa découpe en tranches.To cut bread into slices, it is placed on the bottom of a loading compartment 3 of the slicer. This loading compartment 3 is connected to a receiving compartment 4 from where the bread can be recovered after it has been cut into slices.

Dans le compartiment de chargement 3 est disposé un poussoir 5 qui permet d'agripper le pain à couper et de le déplacer vers le compartiment de réception 4 suivant une direction de déplacement du pain comme indiqué par la flèche 6. Le poussoir 5 est commandé par des moyens de contrôle qui ne sont pas représentés dans les figures, mais qui sont connus par l'homme de métier en soi.In the loading compartment 3 is placed a pusher 5 which makes it possible to grip the bread to be cut and move it towards the receiving compartment 4 following a direction of movement of the bread as indicated by the arrow 6. The pusher 5 is controlled by control means which are not shown in the figures, but which are known to those skilled in the art.

Pour couper le pain en tranches, une lame de coupe circulaire 7 est prévue, comme le montre la figure 1. Cette lame de coupe 7 peut être déplacée suivant un plan de coupe qui s'étend entre le compartiment de chargement 3 et le compartiment de réception 4 et sensiblement perpendiculairement par rapport à ladite direction de déplacement. Ainsi, lorsqu'un pain est déplacé du compartiment de chargement 3 vers le compartiment de réception 4, suivant ladite direction de déplacement 6, des tranches successives sont découpées du pain du pain.To cut the bread into slices, a circular cutting blade 7 is provided, as shown in figure 1 . This cutting blade 7 can be moved along a cutting plane which extends between the loading compartment 3 and the receiving compartment 4 and substantially perpendicular to said direction of movement. Thus, when a loaf is moved from loading compartment 3 towards the receiving compartment 4, following said direction of movement 6, successive slices are cut from the loaf of bread.

Le compartiment de chargement 3 est séparé du compartiment de réception 4 par une fente 8 à travers laquelle la lame de coupe circulaire 7 peut se déplacer pour couper des tranches successives d'un pain. La lame circulaire 7 est, de préférence, entraînée autour de son axe et peut, en même temps, se déplacer, par exemple, suivant un mouvement de va-et-vient à travers la fente 8 selon le plan de coupe pour couper des tranches successives d'un pain qui est avancé suivant la direction de déplacement 6.The loading compartment 3 is separated from the receiving compartment 4 by a slot 8 through which the circular cutting blade 7 can move to cut successive slices of a loaf. The circular blade 7 is preferably driven around its axis and can, at the same time, move, for example, back and forth through the slot 8 along the cutting plane to cut slices successive phases of a loaf which is advanced in the direction of movement 6.

Dans la forme de réalisation de la trancheuse, suivant l'invention, représentée aux figures 1 et 2, la lame de coupe circulaire 7 et, par conséquent, la fente 8 s'étendent sensiblement transversalement par rapport au côté avant de la trancheuse 1. Il est également possible que la direction de déplacement 6 du pain s'étend sensiblement transversalement par rapport au côté avant de la trancheuse et que la lame de coupe circulaire 7 et la fente 8 s'étendent parallèlement à le long de ce côté avant.In the embodiment of the slicer, according to the invention, represented in figures 1 and 2 , the circular cutting blade 7 and, consequently, the slot 8 extend substantially transversely with respect to the front side of the slicer 1. It is also possible that the direction of movement 6 of the bread extends substantially transversely with respect to the front side of the slicer and that the circular cutting blade 7 and the slot 8 extend parallel to along this front side.

La trancheuse 1, suivant l'invention, comprend également un support de tranches 9, comme le montre schématiquement la figure 2. Ce support de tranches 9 s'étend dans le compartiment de réception 4 et est destiné à exercer une force de pression contre la partie déjà coupée du pain. Ainsi, lorsqu'un pain est déplacé du compartiment de chargement 3 vers le compartiment de réception 4, ce support 9 s'appuie contre le bout du pain qui entre qui entre le compartiment de réception 4.The slicer 1, according to the invention, also comprises a slice support 9, as shown schematically in figure 2 . This slice support 9 extends into the receiving compartment 4 and is intended to exert a pressure force against the already cut part of the bread. Thus, when a loaf is moved from the loading compartment 3 to the receiving compartment 4, this support 9 rests against the end of the loaf which enters the receiving compartment 4.

Lorsque le pain avance dans ce compartiment de réception 4, des tranches successives sont découpées du pain et le support de tranches 10 exerce un force de poussée sur la première tranche qui a été découpée afin de maintenir les tranches découpées successivement l'une contre l'autre. A cet effet, le support de tranches 10 est mobile et peut se déplacer autour d'un axe de pivot 11 pour maintenir le support en contact avec la partie du pain coupée au fur et à mesure que cette partie coupée avance dans le compartiment de réception 4.When the bread advances into this receiving compartment 4, successive slices are cut from the bread and the slice support 10 exerts a pushing force on the first slice which has been cut in order to maintain the slices cut successively against each other. other. For this purpose, the slice support 10 is mobile and can move around a pivot axis 11 to keep the support in contact with the cut part of the bread as this cut part advances in the receiving compartment 4.

Le support de tranches 9 coopère avec un ressort à lames qui présente une lame 10. Cette lame 10 exerce une force de poussée sur le support de tranches 9 afin de maintenir ce support 9 en appui contre la partie du pain coupée.The slice support 9 cooperates with a leaf spring which has a blade 10. This blade 10 exerts a pushing force on the slice support 9 in order to keep this support 9 resting against the cut part of the bread.

Selon l'invention, un système de réglage est prévu qui permet de modifier la position de l'une des extrémités 12 de la lame 10 par rapport au bâti 2 de la trancheuse 1 pour régler la force de poussée exercée sur le support de tranches 9 et par, par conséquent, la force de poussée qui est exercée sur les tranches du pain coupé.According to the invention, an adjustment system is provided which makes it possible to modify the position of one of the ends 12 of the blade 10 relative to the frame 2 of the slicer 1 to adjust the thrust force exerted on the slice support 9 and, consequently, the thrust force which is exerted on the slices of the cut bread.

Ce système de réglage comprend un élément rotatif 13 qui peut être entrainé autour d'un axe 14 et des moyens de transformation de mouvement pour transformer un mouvement rotatif de l'élément rotatif 13 en un mouvement de translation de ladite extrémité 12 de la lame par rapport au bâti 2. Ceci est illustré dans la figure 5.This adjustment system comprises a rotary element 13 which can be driven around an axis 14 and movement transformation means for transforming a rotary movement of the rotary element 13 into a translation movement of said end 12 of the blade by relation to frame 2. This is illustrated in the Figure 5 .

Dans la forme de réalisation de l'invention qui est montrée dans la figure 5, l'élément rotatif 13 du système de réglage comprend une vis 15 qui, d'une part, agisse sur l'extrémité 12 de la lame 10 et qui, d'autre part, coopère avec un écrou 16 fixé par rapport à ladite extrémité 12 de lame 10. En particulier, cet écrou 16 fait part d'une pièce métallique 17 en forme de L qui est montée à glissement par rapport à un profilé 18. Ladite extrémité 12 de la lame 10 est fixé à la pièce métallique 17 qui peut se déplacer suivant un mouvement de translation suivant la direction de l'axe 14 par rapport au profilé 18. Le profilé 18 est fixé au bâti 2. Ainsi, l"extrémité 12 de la lame 10 peut se déplacer par rapport au bâti 2. L'extrémité opposée 19 de la lame 10, opposée à l'extrémité 12 susdite, est fixé à ce profilé 18.In the embodiment of the invention which is shown in the figure 5 , the rotating element 13 of the adjustment system comprises a screw 15 which, on the one hand, acts on the end 12 of the blade 10 and which, on the other hand, cooperates with a nut 16 fixed relative to said end 12 of blade 10. In particular, this nut 16 is part of an L-shaped metal part 17 which is slidably mounted relative to a profile 18. Said end 12 of the blade 10 is fixed to the metal part 17 which can move following a translation movement in the direction of the axis 14 relative to the profile 18. The profile 18 is fixed to the frame 2. Thus, the end 12 of the blade 10 can move relative to the frame 2. The opposite end 19 of the blade 10, opposite the aforementioned end 12, is fixed to this profile 18.

Par conséquent, lorsque la vis 15 est tournée par rapport à l'écrou 16, le mouvement rotatif de la vis 15 est transformé en un mouvement de translation ladite extrémité 12 de la lame 10. En particulier, la rotation de la vis 15, qui coopère avec l'écrou 16 de la pièce 17 en forme de L, déplace cet pièce 14 ensemble avec l'extrémité 12 de la lame 10 parallèle à l'axe 14. La tête 20 de la vis 15 est maintenue par le profilé 18 à une position fixe par rapport au bâti 2 et peut tourner librement autour de l'axe 14.Consequently, when the screw 15 is rotated relative to the nut 16, the rotary movement of the screw 15 is transformed into a translation movement of said end 12 of the blade 10. In particular, the rotation of the screw 15, which cooperates with the nut 16 of the L-shaped part 17, moves this part 14 together with the end 12 of the blade 10 parallel to the axis 14. The head 20 of the screw 15 is held by the profile 18 at a fixed position relative to the frame 2 and can rotate freely around the axis 14.

Dans une forme de réalisation alternative de ce système de réglage, l'écrou 16 est fixe par rapport au profilé 18 et l'extrémité de la vis 15 s'appuie contre la pièce 17 contre l'action de poussée de la lame 10. De cette manière, lorsque l'on tourne la vis 15 autour de son axe 14, cette vis est déplacée le long du profilé 18 en déplaçant la pièce 17.In an alternative embodiment of this adjustment system, the nut 16 is fixed relative to the profile 18 and the end of the screw 15 rests against the part 17 against the pushing action of the blade 10. In this way, when we turn the screw 15 around its axis 14, this screw is moved along the profile 18 by moving the part 17.

Ainsi, le système de réglage permet de déplacer les extrémités opposées 12 et 19 de lame 10 l'une par rapport à l'autre afin de régler la tension dans cette lame 10.Thus, the adjustment system makes it possible to move the opposite ends 12 and 19 of blade 10 relative to each other in order to adjust the tension in this blade 10.

Les figures 3 et 5 montrent une forme de réalisation de l'invention dont la trancheuse présente un ressort à lame dont la lame 10 est repliée sur elle-même pour former une boucle. Cette boucle est en contact avec le support de tranches 9 et exerce une force de pression contre ce support 9 le maintenir en contact avec la partie du pain coupé en tranches. Lors de l'avancement de pain dans le compartiment de réception 4, le support de tranches 9 tourne autour du pivot 11, tandis que l'extrémité du support 9, qui est en contact avec la boucle de la lame 10 glisse sur la surface de cette lame 10.THE figures 3 and 5 show an embodiment of the invention in which the slicer has a leaf spring whose blade 10 is folded on itself to form a loop. This loop is in contact with the slice support 9 and exerts a pressure force against this support 9 keeping it in contact with the part of the bread cut into slices. When advancing bread into the receiving compartment 4, the slice support 9 rotates around the pivot 11, while the end of the support 9, which is in contact with the loop of the blade 10 slides on the surface of this blade 10.

L'avantage de cette dernière forme de réalisation de l'invention n'est pas seulement que la force de poussée exercée par le support de tranches 9 sur le pain coupé est réglable, mais également que cette force de pousse reste sensiblement invariable au fur et à mesure de l'avancement du pain coupé. Donc, la force de poussée exercée par le support de tranches 9 est sensiblement indépendante de la position de ce support 9 ou de son déplacement.The advantage of this last embodiment of the invention is not only that the pushing force exerted by the slice support 9 on the cut bread is adjustable, but also that this pushing force remains substantially invariable over time. as the cut bread progresses. Therefore, the thrust force exerted by the wafer support 9 is substantially independent of the position of this support 9 or its movement.

Un avantage important de l'invention est que l'élément rotatif 13 peut être accessible à partir de l'extérieur du bâti 2 pour permettre d'entrainer cet élément rotatif 13 autour dudit axe 14 pour régler la force de poussée exercée par le support de tranches 9, comme montré schématiquement dans la figure 2. Ainsi, la tête 20 de la vis 15 peut s'étendre jusqu'en dehors du bâti 2 ou, dans une autre forme de réalisation, cette tête 20 peut être accessible au moyens de, par exemple, un tournevis à travers une ouverture qui est prévue dans le bâti 2 à cet effet.An important advantage of the invention is that the rotating element 13 can be accessible from the outside of the frame 2 to enable this rotating element 13 to be driven around said axis 14 to adjust the thrust force exerted by the support. slices 9, as shown schematically in the figure 2 . Thus, the head 20 of the screw 15 can extend to the outside of the frame 2 or, in another embodiment, this head 20 can be accessible by means of, for example, a screwdriver through an opening which is provided in frame 2 for this purpose.

Dans encore une autre forme de réalisation de l'invention, l'élément rotatif 13 du système de réglage comprend un pignon coopérant avec une crémaillère fixée par rapport à ladite extrémité 12 de la lame 10. Ainsi, lorsque le pignon est tournée autour de son axe, le mouvement rotatif du pignon est transformé en un mouvement de translation de ladite extrémité 12 de la lame 10.In yet another embodiment of the invention, the rotary element 13 of the adjustment system comprises a pinion cooperating with a rack fixed relative to said end 12 of the blade 10. Thus, when the pinion is rotated around its axis, the rotary movement of the pinion is transformed into a translation movement of said end 12 of the blade 10.

Il est également possible de prévoir un moteur électrique qui coopère avec l'élément rotatif 13 pour l'entrainer autour de l'axe 14. L'élément rotatif 13 peut, par exemple, être constitué, par un moteur électrique.It is also possible to provide an electric motor which cooperates with the rotating element 13 to drive it around the axis 14. The rotating element 13 can, for example, be constituted by an electric motor.
