Description

MACHINE VERTICALE POUR COUPER ET EMPILER DES TRANCHES D'UN PAIN  VERTICAL MACHINE FOR CUTTING AND STACKING SLICES OF A BREAD
ET PROCÉDÉ CORRESPONDANT L'invention concerne une machine à découper automatiquement en tranches un pain ou une denrée analogue. Cette machine comprend un compartiment de chargement connecté à un compartiment de réception et un dispositif de coupe permettant de couper des tranches du pain lorsque celui-ci est déplacé du compartiment de chargement vers le compartiment de réception.  The invention relates to a machine for automatically slicing bread or a similar commodity. This machine comprises a loading compartment connected to a receiving compartment and a cutting device for cutting slices of the bread when it is moved from the loading compartment to the receiving compartment.
Une surface de support pour le pain s'étend dans les deux compartiments et définie une direction de déplacement du pain parallèlement à la surface de support. Dans la surface de support une fente est prévue entre les compartiments susdits s 'étendant essentiellement transversalement par rapport à la direction de déplacement. Le dispositif de coupe peut se déplacer à travers cette fente suivant un mouvement de va-et-vient pour couper des tranches du pain.  A support surface for the bread extends into both compartments and defines a direction of movement of the bread parallel to the support surface. In the support surface a slot is provided between the aforesaid compartments extending substantially transversely to the direction of movement. The cutter can move through this slot in a back-and-forth motion to cut slices of bread.
Le compartiment de chargement comprend une paroi formée par une surface de guidage qui s'étend suivant la direction de déplacement du pain et qui est sensiblement transversale par rapport à la surface de support.  The loading compartment comprises a wall formed by a guide surface which extends in the direction of movement of the bread and is substantially transverse to the support surface.
De telles machines à découper un pain, dans lesquelles le pain est déplacé suivant une direction sensiblement verticale, sont connues par l'art antérieur de la technique.  Such bread slicers, in which the bread is moved in a substantially vertical direction, are known from the prior art.
Le document DE 9310092 décrit une trancheuse de pain dans laquelle le pain est transporté dans une direction verticale et est coupé en tranches lors de son mouvement descendant. De plus, dans la machine de DE 9310092 le pain coupé doit être récupéré dans un compartiment différent de celui dans lequel le pain à couper a été introduit. Le document DE 4431808 propose une trancheuse de pain dans laquelle le pain est coupé en tranches lors de son mouvement ascendant.  DE 9310092 discloses a bread slicer in which the bread is transported in a vertical direction and is sliced during its downward movement. Moreover, in the DE 9310092 machine the cut bread must be recovered in a compartment different from that in which the bread to be cut has been introduced. DE 4431808 discloses a bread slicer in which the bread is cut into slices during its upward movement.
Lors de l'utilisation de telles machines appartenant à l'art antérieur de la technique, la partie non-coupée du pain repose sur la lame de coupe pendant la découpe d'une tranche du pain ou la partie coupée en tranches repose sur la lame de coupe. Ceci peut provoquer plusieurs problèmes, comme, par exemple, le déplacement de la partie non-coupée du pain par rapport aux tranches coupées ou la déformation de la mie du pain. Ainsi, la formation d'un entassement automatique régulier des tranches coupées du pain se révèle être problématique. Suite au frottement entre la lame de coupe et le pain, les tranches découpées ont tendance à être emportées quelque peu par le mouvement de la lame. Ceci empêche que les tranches coupées successivement sont entassées régulièrement l'une sur l'autre. When using such machines belonging to the prior art, the uncut part of the bread rests on the cutting blade during cutting of a slice of bread or the sliced portion rests on the blade cutting. This can cause several problems, such as, for example, moving the uncut portion of the bread relative to cut slices or the deformation of the crumb of the bread. Thus, the formation of a regular automatic packing of cut slices of bread proves to be problematic. Following the friction between the cutting blade and the bread, the cut slices tend to be carried away somewhat by the movement of the blade. This prevents the successively cut slices from being piled up on one another regularly.
L'invention a pour but de remédier à ces problèmes en offrant une machine à couper automatiquement un pain dans laquelle les tranches découpées du pain sont empilées les unes sur les autres d'une manière régulière lors de sa découpe pendant son mouvement descendant.  The invention aims to remedy these problems by providing a machine to automatically cut a bread in which the cut slices of the bread are stacked on one another in a regular manner during its cutting during its downward movement.
A cet effet, suivant l'invention, la machine comprend une surface d'appui qui s'étend dans le compartiment de réception dans le prolongement de la surface de guidage et qui est séparée de cette dernière par une fente pour permettre le passage du dispositif de coupe à travers cette fente. La surface d'appui est suivie par une surface de glissement formant un évasement du compartiment de réception permettant une chute libre d'une tranche coupée du pain vers sa partie déjà coupée.  For this purpose, according to the invention, the machine comprises a bearing surface which extends in the receiving compartment in the extension of the guide surface and which is separated from the latter by a slot to allow the passage of the device cutting through this slit. The bearing surface is followed by a sliding surface forming a flaring of the receiving compartment allowing a free fall of a cut slice of bread towards its already cut portion.
Avantageusement, la machine comprend une gouttière s'étendant suivant la direction de déplacement du pain pour guider ce dernier lors de son déplacement entre le compartiment de chargement et le compartiment de réception. Cette gouttière présentant un fond formé par la surface de support susdite. Une paroi latérale de cette gouttière comprend ladite surface de guidage, la surface d'appui et la surface de glissement, cette dernière formant un évasement de la gouttière dans une direction sensiblement parallèle à la surface de support.  Advantageously, the machine comprises a gutter extending in the direction of movement of the bread to guide the latter during its movement between the load compartment and the receiving compartment. This gutter having a bottom formed by the supdite support surface. A side wall of this channel comprises said guide surface, the bearing surface and the sliding surface, the latter forming a flare of the channel in a direction substantially parallel to the support surface.
Suivant une forme de réalisation particulière de l'invention, le dispositif de coupe comprend une lame circulaire s'étendant dans le plan de coupe. Cette lame est montée sur un bras d'entraînement permettant de soumettre la lame à un mouvement de va-et-vient dans le plan de coupe pendant que la lame est entraînée autour de son axe central.  According to a particular embodiment of the invention, the cutting device comprises a circular blade extending in the cutting plane. This blade is mounted on a drive arm for subjecting the blade to reciprocate in the cutting plane as the blade is driven about its central axis.
Suivant une forme de réalisation intéressante de l'invention, la surface de glissement comprend une partie inclinée par rapport à la direction de déplacement du pain, qui est connectée à la surface d'appui, et une partie s'étendant sensiblement parallèle à la surface de guidage. Suivant une forme de réalisation préférentielle de l'invention, le compartiment de réception présente une paroi latérale comprenant la surface d'appui et la surface de glissement. According to an advantageous embodiment of the invention, the sliding surface comprises a portion inclined with respect to the direction of movement of the bread, which is connected to the bearing surface, and a portion extending substantially parallel to the surface. guidance. According to a preferred embodiment of the invention, the receiving compartment has a side wall comprising the bearing surface and the sliding surface.
Suivant une forme de réalisation particulière de l'invention, un poussoir avec des moyens d'accrochage est prévu permettant de saisir l'extrémité supérieure du pain. Ce poussoir est mobile suivant la direction de déplacement du pain pour permettre de déplacer le pain vers le compartiment de réception lors de sa découpe en tranches.  According to a particular embodiment of the invention, a pusher with hooking means is provided for gripping the upper end of the bread. This pusher is movable in the direction of movement of the bread to allow the bread to move to the receiving compartment when sliced.
D'une manière intéressante, la machine comprend un support mobile pour maintenir la partie coupée du pain, des moyens d'entraînement étant prévus pour déplacer le support mobile suivant la direction de déplacement du pain.  In an interesting way, the machine comprises a movable support for holding the cut portion of the bread, drive means being provided for moving the movable support in the direction of movement of the bread.
L'invention concerne également un procédé pour découper automatiquement en tranches un pain ou une denrée analogue, suivant lequel on place un pain dans un compartiment de chargement contre une surface de support et contre une surface de guidage s 'étendant sensiblement transversalement par rapport à la surface de support d'une manière telle à ce qu'une zone du pain, présentant la section la plus large transversalement par rapport à la surface de support, vient en contact avec la surface de guidage. On déplace le pain ensuite en descendant, suivant une direction de déplacement, vers un compartiment de réception pendant qu'il glisse contre la surface de support. Ladite direction de déplacement est sensiblement verticale ou inclinée d'un angle inférieur à 45° par rapport à une direction verticale.  The invention also relates to a method for automatically slicing a bread or similar product, wherein a bread is placed in a loading compartment against a support surface and against a guiding surface extending substantially transversely to the supporting surface in such a way that an area of the bread, having the widest section transversely to the support surface, comes into contact with the guide surface. The bread is then moved downward along a direction of travel to a receiving compartment as it slides against the support surface. Said displacement direction is substantially vertical or inclined at an angle less than 45 ° with respect to a vertical direction.
Lors du déplacement du pain, celui-ci est coupé en tranches entre le compartiment de chargement et le compartiment de réception selon un plan de coupe par un dispositif de coupe se déplaçant suivant un mouvement de va-et-vient vers le côté de la surface de guidage. Les tranches découpées sont successivement empilées en- dessous du plan de coupe en formant un empilage présentant des tranches parallèles dans le compartiment de réception. Cet empilage est déplacé vers le bas suivant ladite direction de déplacement.  When moving the bread, it is sliced between the loading compartment and the receiving compartment according to a cutting plane by a cutting device moving in a reciprocating movement towards the side of the surface guidance. The cut slices are successively stacked below the section plane forming a stack having parallel slices in the receiving compartment. This stack is moved downward along said direction of travel.
Ce procédé est caractérisé par le fait que, lorsqu'une tranche est découpée de ladite zone du pain, cette zone est soutenue latéralement par ladite surface de guidage au-dessus du plan de coupe et par une surface d'appui en-dessous de ce plan. L'empilage est alors déplacé à une distance de ce plan de coupe qui est supérieure à la hauteur de la surface d'appui dans la direction de déplacement du pain plus l'épaisseur de la tranche concernée pour permettre la chute de cette tranche après sa découpe sur l'empilage. This method is characterized in that, when a wafer is cut from said bread zone, this zone is supported laterally by said guiding surface above the cutting plane and by a bearing surface beneath it. plan. The stack is then moved at a distance from this cutting plane which is greater than the height of the bearing surface in the direction of movement of the bread plus the thickness of the slice concerned to allow the slice to fall after being cut on the stack.
Suivant une forme de réalisation préférentielle du procédé, suivant l'invention, on saisit l'extrémité supérieure du pain après qu'il a été placé contre ladite surface de support et on maintient cette extrémité à Γ encontre de la gravité lors de son déplacement descendant pendant que des tranches sont coupées.  According to a preferred embodiment of the method, according to the invention, the upper end of the bread is seized after it has been placed against said support surface and this end is held against the gravity during its downward movement. while slices are cut.
Suivant une forme de réalisation particulière du procédé, suivant l'invention, le pain est déplacé vers le compartiment de réception suivant des pas discrets correspondant approximativement à l'épaisseur des tranches en maintenant l'extrémité supérieure du pain jusqu'à sa découpe complète en tranches.  According to a particular embodiment of the method, according to the invention, the bread is moved to the receiving compartment in discrete steps corresponding approximately to the thickness of the slices while maintaining the upper end of the bread until it is completely cut out. slices.
De préférence, l'empilage formé par le pain découpé est, après sa découpe complète, transporté dans ladite direction de déplacement vers le compartiment de chargement afin de pouvoir le récupérer à l'état découpé.  Preferably, the stack formed by the cut bread is, after its complete cutting, transported in said direction of movement to the loading compartment so as to be able to recover it in the cut-out state.

Dans les différentes figures, les mêmes chiffres de référence concernent des éléments analogues ou identiques.  In the different figures, the same reference numerals relate to similar or identical elements.
La machine, suivant l'invention, constitue, en général, une trancheuse à pain automatique dans laquelle un pain à couper est déplacé suivant une direction de déplacement dans la machine. Lors de ce déplacement, les tranches sont coupées l'une après l'autre dans une direction transversale par rapport à ladite direction de déplacement.  The machine according to the invention is, in general, an automatic bread slicer in which a bread to be cut is moved in a direction of movement in the machine. During this movement, the slices are cut one after the other in a direction transverse to said direction of displacement.
Pour couper le pain en tranches, celui-ci est placé dans un compartiment de chargement 1 d'une trancheuse, comme représenté dans la figure 1. Ce compartiment 1 présente une surface de support 2 pour le pain 3 présentant une plaque qui s'étend sensiblement verticalement ou qui est inclinée d'un angle a inférieur à 30°, en particulier, inférieur à 20°, par rapport à la verticale.  To cut the bread in slices, it is placed in a loading compartment 1 of a slicer, as shown in FIG. 1. This compartment 1 has a support surface 2 for the bread 3 having a plate which extends substantially vertically or which is inclined at an angle a less than 30 °, in particular less than 20 °, with respect to the vertical.
Cette surface de support 2 s'étend jusque dans un compartiment de réception 4 et présente une fente 5 qui délimite ce compartiment de réception 1 par rapport au compartiment de chargement 4.  This support surface 2 extends into a receiving compartment 4 and has a slot 5 which defines this receiving compartment 1 with respect to the loading compartment 4.
Le compartiment de chargement 1 présente également une paroi formée par une surface de guidage 11 qui s'étend jusque dans le compartiment de réception 4. La surface de guidage 11 s'étend sensiblement transversalement par rapport à la surface de support 2 et présente une fente 12 entre les deux compartiments 1 et 4.  The loading compartment 1 also has a wall formed by a guide surface 11 which extends into the receiving compartment 4. The guide surface 11 extends substantially transversely to the support surface 2 and has a slot 12 between the two compartments 1 and 4.
La machine comprend également un support mobile 6 pour le pain 3 s'étendant, de préférence, transversalement par rapport à la surface de support 2. Ce support mobile 6 est entraîné, par exemple, par un moteur électrique pour transporter le pain 3 du compartiment de chargement 1 vers le compartiment de réception 4 et vice- versa. Pour couper le pain 2 en tranches, celui-ci est placé avec le côté, qui forme le fond du pain 3, contre la surface de support 2 dans le compartiment de chargement 1 pendant qu'il est supporté par le support mobile 6. Le pain 3 s'appuie, de préférence, avec un côté latéral contre la surface de guidage 11. Le pain 3 subit alors un déplacement descendant vers le compartiment de réception 4 pendant qu'il est guidé par la surface de support 2 et par la surface de guidage 11 suivant un mouvement correspondant du support mobile 6. Ainsi, cette surface de support 2 détermine la direction de déplacement du pain, suivant laquelle le pain 3 et le support mobile 6 sont déplacés. The machine also comprises a mobile support 6 for the bread 3 extending, preferably, transversely with respect to the support surface 2. This mobile support 6 is driven, for example, by an electric motor to transport the bread 3 of the compartment from loading 1 to the receiving compartment 4 and vice versa. To cut the bread 2 into slices, it is placed with the side, which forms the bottom of the bread 3, against the support surface 2 in the loading compartment 1 while it is supported by the mobile support 6. The The bread 3 preferably bears with a lateral side against the guide surface 11. The bread 3 then undergoes a downward movement towards the receiving compartment 4 while it is guided by the supporting surface 2 and by the surface In this way, this support surface 2 determines the direction of movement of the bread, according to which the bread 3 and the movable support 6 are moved.
Lors du mouvement du pain 3, celui-ci est coupé en tranches au moyen d'un dispositif de coupe 7 comprenant une lame de coupe 8 qui se déplace à travers le pain 3 suivant une direction horizontale ou transversale par rapport à la direction de déplacement, comme représenté schématiquement dans la figure 2. Lors de la découpe d'une tranche du pain 3, le dispositif de coupe 7 se déplace à travers les fentes 5 et 12.  During the movement of the bread 3, it is sliced by means of a cutting device 7 comprising a cutting blade 8 which moves through the bread 3 in a direction horizontal or transverse to the direction of movement as shown diagrammatically in FIG. 2. When cutting a slice of the bread 3, the cutting device 7 moves through the slits 5 and 12.
La lame de coupe 8 comprend une lame circulaire qui est entraînée autour de son axe central, comme indiqué par la flèche 9, pendant qu'elle est déplacée à travers le pain 3, comme indiqué par la flèche 10, dans la direction de la surface de guidage 11. Après chaque passage de la lame de coupe 8, le pain 3 est descendu d'une distance correspondant plus ou moins à l'épaisseur d'une tranche avant de couper la tranche suivante. Le dispositif de coupe 7 est donc déplacé suivant un mouvement de va-et-vient. Ainsi, un pain coupé est obtenu dont les tranches sont empilées sur le support mobile 6.  The cutting blade 8 comprises a circular blade which is driven about its central axis, as indicated by the arrow 9, as it is moved through the bread 3, as indicated by the arrow 10, in the direction of the surface 11. After each passage of the cutting blade 8, the bread 3 is lowered by a distance corresponding more or less to the thickness of a wafer before cutting the next wafer. The cutting device 7 is moved in a back and forth motion. Thus, a cut bread is obtained whose slices are stacked on the mobile support 6.
Après que le pain 3 ait été coupé complètement en tranches, comme représenté dans la figure 3, l'empilage, formé par les tranches du pain 3, est transporté suivant ladite direction de déplacement vers le compartiment de chargement 1 pour pouvoir récupérer le pain 3 à l'état découpé.  After the bread 3 has been cut completely slices, as shown in Figure 3, the stack, formed by the slices of the bread 3, is transported in said direction of movement to the load compartment 1 to be able to recover the bread 3 in the cut state.
Généralement, après que le pain ait été placé contre ladite surface de support pour le couper en tranches, on saisit l'extrémité supérieure du pain 3 et on maintient cette extrémité à Γ encontre de la gravité lors de son déplacement descendant pendant que des tranches sont coupées. A cet effet, un poussoir mobile 13 est prévu dans le compartiment de chargement 1. Ce poussoir 13 présente des moyens d'accrochage sous forme de crochets mobiles 14 permettant de saisir l'extrémité supérieure du pain 3. Le poussoir 13 est entraîné suivant la direction de déplacement du pain 3 et permet de le déplacer vers le compartiment de réception lors de sa découpe en tranches en maintenant son extrémité supérieure. La partie non-coupée du pain 3 est, par conséquent, suspendue au poussoir 13 par les crochets 14 lors de sa découpe. Generally, after the bread has been placed against said support surface to slice it, the upper end of the bread 3 is grasped and this end is held against the gravity during its downward movement while slices are cut. For this purpose, a mobile pusher 13 is provided in the loading compartment 1. This pusher 13 has hooking means in the form of movable hooks 14 for grasping the end 3. The pusher 13 is driven in the direction of movement of the bread 3 and allows to move it to the receiving compartment when slicing it while maintaining its upper end. The uncut portion of the bread 3 is, therefore, suspended from the pusher 13 by the hooks 14 during its cutting.
Dans une trancheuse à pain automatique, suivant l'art antérieur, comme représentée aux figures 1 à 4, l'entassement des tranches découpées du pain est généralement irrégulier. De plus, suite à cet entassement irrégulier, lorsque le pain coupé en tranches est déplacé du compartiment de réception 4 vers le compartiment de chargement 1, les tranches les plus larges s'accrochent au bord inférieur de la partie de la surface de guidage 11 s 'étendant dans le compartiment de chargement 1.  In an automatic bread slicer, according to the prior art, as represented in FIGS. 1 to 4, the packing of the cut slices of the bread is generally irregular. In addition, following this irregular packing, when the sliced bread is moved from the receiving compartment 4 to the loading compartment 1, the wider slices cling to the lower edge of the portion of the guide surface 11 extending into the load compartment 1.
La figure 5 montre, dans un tel cas, l'empilage des tranches découpées dans le compartiment de réception 4. Suite au mouvement de la lame 8 à travers le pain 3 vers la surface de guidage 11, les tranches 15 sont quelque peu emmenées par la lame 8. Ceci est surtout le cas pour les tranches qui proviennent de l'endroit de la zone du pain présentant la section la plus large transversalement par rapport à la surface de support 1.  FIG. 5 shows, in such a case, the stacking of the cut slices in the receiving compartment 4. Following the movement of the blade 8 through the bread 3 towards the guiding surface 11, the slices 15 are taken somewhat by the blade 8. This is especially the case for the slices that come from the place of the bread zone having the widest section transversely to the support surface 1.
Ainsi, un empilage de tranches 15 est obtenu, dont les tranches s'appuient contre la surface de guidage 11 et sont inclinées contre cette surface 11 , comme montré schématiquement à la figure 5.  Thus, a stack of slices 15 is obtained, the slices of which bear against the guide surface 11 and are inclined against this surface 11, as shown schematically in FIG. 5.
L'invention propose de remédier à ce problème, comme montré aux figures 6 et 7. Ainsi, la machine suivant l'art antérieur, comme décrite ci-dessus, est modifiée en présentant une forme alternative pour la partie de la surface de guidage 1 1 qui s'étend dans le compartiment de réception 4.  The invention proposes to remedy this problem, as shown in Figures 6 and 7. Thus, the machine according to the prior art, as described above, is modified by having an alternative form for the portion of the guide surface 1 1 which extends into the receiving compartment 4.
La machine à découper un pain 3 automatiquement en tranches, suivant l'invention, comprend une surface d'appui 16, qui s'étend dans le compartiment de réception 4 dans le prolongement de la surface de guidage 11. Cette surface d'appui 16 est séparée de la surface de guidage 11 par la fente 12 pour permettre le passage du dispositif de coupe 7 à travers cette fente 12. Le bord supérieur de cette surface d'appui 16 s'étend donc dans le plan de la surface de guidage 2 et, de préférence, parallèlement au plan de coupe. Ceci permet que le pain 3 se déplace, sans s'accrocher aux bords de la fente 12, par-dessus de cette fente vers le compartiment de chargement 1 ou vers le compartiment de réception 4. La surface d'appui 16 est suivie par une surface de glissement 17 qui forme un évasement du compartiment de réception 4. Cette surface de glissement 17 présente une première partie adjacente à la surface d'appui 16, qui est inclinée par rapport à cette dernière, et une deuxième partie 18, s 'étendant sensiblement parallèlement à la surface de guidage 11. Cette deuxième partie 18 est optionnelle et est décalée par rapport à la surface de guidage 11. The slicing machine 3 automatically slices, according to the invention, comprises a bearing surface 16, which extends into the receiving compartment 4 in the extension of the guide surface 11. This bearing surface 16 is separated from the guide surface 11 by the slot 12 to allow the passage of the cutting device 7 through this slot 12. The upper edge of this bearing surface 16 thus extends in the plane of the guide surface 2 and, preferably, parallel to the cutting plane. This allows the bread 3 to move, without clinging to the edges of the slot 12, over this slot to the loading compartment 1 or to the receiving compartment 4. The bearing surface 16 is followed by a sliding surface 17 which forms a flaring of the receiving compartment 4. This sliding surface 17 has a first portion adjacent to the bearing surface 16, which is inclined relative thereto , and a second portion 18, extending substantially parallel to the guide surface 11. This second portion 18 is optional and is offset with respect to the guide surface 11.
La machine, suivant l'invention, comprend donc une gouttière qui s'étend suivant la direction de déplacement du pain 3 pour guider ce dernier lors de son déplacement entre le compartiment de chargement 1 et le compartiment de réception 4. La surface de support 2 forme le fond de cette gouttière et l'ensemble de ladite surface de guidage 11, de la surface d'appui 16 et de la surface de glissement 17 fait partie d'une paroi latérale de cette gouttière. La surface d'appui 16 définie, en particulier, un évasement de la gouttière dans une direction sensiblement parallèle à la surface de support 2 et transversale par rapport à la surface de guidage 11.  The machine, according to the invention, therefore comprises a gutter which extends in the direction of movement of the bread 3 to guide the latter during its movement between the load compartment 1 and the receiving compartment 4. The support surface 2 forms the bottom of this channel and all of said guide surface 11, the bearing surface 16 and the sliding surface 17 is part of a side wall of the gutter. The bearing surface 16 defines, in particular, a flare of the channel in a direction substantially parallel to the support surface 2 and transverse to the guide surface 11.
Comme illustré aux figures 6 et 7, le dispositif de coupe 7 comprend une lame circulaire 8 qui s'étend dans le plan de coupe. Cette lame 8 est montée sur un bras d'entraînement 18, dont une extrémité est montée à pivotement par rapport au châssis de la machine, tandis que l'extrémité opposée 19 de ce bras 18 présente la lame circulaire 8. Le bras d'entraînement est déplacé suivant un mouvement de va-et-vient selon le plan de coupe afin de diriger la lame 8 vers la surface de guidage 11 à travers la fente 12 pour couper des tranches successives. Le bras d'entraînement est déplacé, ensemble avec la lame 8, à travers la fente 5 lors de son mouvement de va-et-vient pour couper des tranches du pain. Simultanément, la lame 8 est entraînée autour de son axe central. Suite au mouvement du bras 18, la lame 8 traverse également la fente 12 adjacente à la surface de guidage 11 et la surface d'appui 16.  As illustrated in FIGS. 6 and 7, the cutting device 7 comprises a circular blade 8 which extends in the plane of section. This blade 8 is mounted on a drive arm 18, one end of which is pivotally mounted relative to the frame of the machine, while the opposite end 19 of this arm 18 has the circular blade 8. The drive arm is moved reciprocatingly along the cutting plane to direct the blade 8 to the guide surface 11 through the slot 12 to cut successive slices. The driving arm is moved together with the blade 8, through the slot 5 during its movement back and forth to cut slices of the bread. Simultaneously, the blade 8 is driven around its central axis. Following the movement of the arm 18, the blade 8 also passes through the slot 12 adjacent to the guide surface 11 and the bearing surface 16.
Le bras d'entraînement 18 est monté à la face inférieure de la lame 8, de telle sorte que la face supérieure de cette lame 8 est maintenue sensiblement lisse pour éviter tout accrochage au pain 3 pendant la découpe des tranches.  The drive arm 18 is mounted on the lower face of the blade 8, so that the upper face of the blade 8 is held substantially smooth to prevent snagging on the bread 3 during slicing.
L'extrémité 19 du bras d'entraînement 18, qui s'étend en-dessous de la lame 8, présente une surface latérale inclinée en forme de coin. Ainsi, le contact entre le bras d'entraînement 18 et une tranche 15, qui est découpée du pain 3, est évité. S'il y aurait néanmoins un contact entre l'extrémité 19 du bras 18 et la tranche 15, cette tranche 15 est conduite vers l'empilage des tranches, suite à la présence de la surface latérale inclinée. The end 19 of the drive arm 18, which extends below the blade 8, has a wedge-shaped inclined side surface. Thus, the contact between the drive arm 18 and a wafer 15, which is cut from the bread 3, is avoided. If there is nevertheless a contact between the end 19 of the arm 18 and the slice 15, this slice 15 is led to stacking slices, following the presence of the inclined side surface.
Dans les figures 8 à 12 la découpe des tranches du pain, suivant l'invention, est expliquée. Comme illustré dans la figure 8, un pain 3 à couper en tranches est placé sur le support mobile 6 dans le compartiment de réception 1. Ce pain est positionné avec le fond contre la surface de support 2 et avec son côté latéral en contact avec la surface de guidage 1 1. En particulier, la zone 20 du pain 3, présentant la section la plus large transversalement par rapport à la surface de support 2, est mise en contact avec la surface de guidage 2. Ensuite, le poussoir 13 est déplacé jusqu'à l'extrémité supérieure du pain 3 pour que les crochets 14 du poussoir 13 puissent saisir cette extrémité.  In Figures 8 to 12 the cutting of the slices of the bread according to the invention is explained. As illustrated in FIG. 8, a slicing bread 3 is placed on the mobile support 6 in the receiving compartment 1. This bread is positioned with the bottom against the support surface 2 and with its lateral side in contact with the In particular, the area 20 of the bread 3, having the widest section transversely to the support surface 2, is brought into contact with the guide surface 2. Then, the pusher 13 is moved up to the upper end of the bread 3 so that the hooks 14 of the pusher 13 can grasp this end.
Dans le cas représenté à la figure 8, le support mobile 6 est positionné en-dessous du niveau du plan de coupe. Avant d'entamer la découpe en tranches du pain, le poussoir 13 est remonté d'une distance suffisante pour qu'une première tranche de l'extrémité inférieure du pain 3 puisse être découpée. Ainsi, le pain 3 est suspendu au poussoir 13 au moyen des crochets 14. Eventuellement, le support mobile 6 est descendu d'une certaine distance afin de créer un espace entre le support mobile 6 et le pain 3 qui permet que les tranches découpées tombent vers le support mobile 6, comme décrit ci-dessous.  In the case shown in FIG. 8, the mobile support 6 is positioned below the level of the section plane. Before starting the slicing bread, the pusher 13 is raised a sufficient distance for a first slice of the lower end of the bread 3 can be cut. Thus, the bread 3 is suspended from the pusher 13 by means of the hooks 14. Optionally, the mobile support 6 is lowered by a certain distance in order to create a space between the mobile support 6 and the bread 3 which allows the cut slices to fall. towards the mobile support 6, as described below.
Le pain 3 est ensuite déplacé en descendant, suivant la direction de déplacement, vers le compartiment de réception 4, en entraînant le support mobile 6 et le poussoir 13. Lors de ce déplacement avec des pas discrets correspondant à l'épaisseur d'une tranche, ou approximativement correspondant à l'épaisseur d'une tranche, le pain glisse contre la surface de support 2 et des tranches 15 sont découpées du pain 3, comme illustré dans les figures 9 et 10, par le mouvement de va-et-vient de la lame 8 suivant le plan de coupe entre le compartiment de chargement 1 et le compartiment de réception 4. La lame 8 se déplace d'une manière synchronisée avec l'avancement du pain 8 vers le compartiment de réception 4.  The bread 3 is then moved downwards, in the direction of movement, towards the receiving compartment 4, driving the mobile support 6 and the pusher 13. During this movement with discrete steps corresponding to the thickness of a slice , or approximately corresponding to the thickness of a slice, the bread slides against the support surface 2 and slices 15 are cut from the bread 3, as shown in Figures 9 and 10, by the movement back and forth of the blade 8 along the cutting plane between the loading compartment 1 and the receiving compartment 4. The blade 8 moves in a manner synchronized with the advance of the bread 8 towards the receiving compartment 4.
Les tranches 15 découpées sont successivement empilées sur le support mobile 6, en-dessous du plan de coupe, en formant un empilage 21 présentant des tranches 15 parallèles dans le compartiment de réception 4. Pendant la découpe en tranches du pain 3 cet empilage 21 est déplacé vers le bas suivant ladite direction de déplacement. Avant de découper une tranche 15, le support mobile 6 est descendu ensemble avec l'empilage 21, afin de créer une distance, entre l'empilage et la tranche 15 qui sera découpée du pain 3, qui soit suffisante pour que cette tranche 15 puisse tomber en chute libre, après sa découpe, vers l'empilage 21, comme illustré à la figure 9. Par le fait que cette tranche 15 peut tomber librement, sans être encombrée, elle se pose d'une manière régulière sur l'empilage 21 et parallèlement aux tranches déjà contenues dans cet empilage 21. The slices 15 cut are successively stacked on the mobile support 6, below the cutting plane, forming a stack 21 having parallel slices 15 in the receiving compartment 4. During the slicing of the bread 3 this stack 21 is moved downward along said direction of travel. Before cutting a wafer 15, the mobile support 6 is lowered together with the stack 21, in order to create a distance between the stack and the wafer 15 that will be cut from the bread 3, which is sufficient for this wafer 15 to falling freely, after cutting, to the stack 21, as shown in Figure 9. In that this wafer 15 can fall freely, without being congested, it is posed in a regular manner on the stack 21 and parallel to the slices already contained in this stack 21.
De préférence, ladite distance entre l'empilage et le pain est au moins égale à l'épaisseur d'une tranche 15 et, de préférence, supérieure à cette épaisseur ou supérieure au total de la hauteur du bras d'entraînement 18 dans le compartiment de réception 4, suivant la direction de déplacement du pain, et l'épaisseur d'une tranche 15.  Preferably, said distance between the stack and the bread is at least equal to the thickness of a wafer 15 and, preferably, greater than this thickness or greater than the total of the height of the drive arm 18 in the compartment 4, in the direction of movement of the bread, and the thickness of a wafer 15.
Lorsqu'une tranche 15 est découpée de ladite zone 20 du pain 3, cette zone 20 est soutenue latéralement par la surface de guidage 11 au-dessus du plan de coupe et par la surface d'appui 16 en-dessous de ce plan, comme illustré dans la figure 10. Avant que la tranche 15 tombe en chute libre vers l'empilage 21, ce dernier est déplacé à une distance du plan de coupe qui est supérieure à la hauteur de la surface d'appui 16, dans la direction de déplacement du pain 3, en plus de l'épaisseur de la tranche 15 concernée. Ainsi, la tranche 15, qui vient d'être découpée, peut tomber en chute libre vers l'empilage 21 sans qu'elle vienne en contact avec la paroi latérale du compartiment de réception 4 à la hauteur de l'évasion formée par la surface de glissement 17. Même si une tranche 15 est déplacée latéralement vers la surface d'appui 16, suite au frottement qui pourrait être présent entre la lame 8 et cette tranche 15, une chute libre de la tranche 15 est obtenue par la présence de l'évasement du compartiment de réception 4 formé par la surface de glissement 17. En particulier, la tranche 15 tombe en chute libre dans l'espace entre le niveau inférieur de la surface d'appui 16 et le côté supérieur de l'empilage 21.  When a wafer 15 is cut from said zone 20 of the bread 3, this zone 20 is supported laterally by the guiding surface 11 above the cutting plane and by the bearing surface 16 below this plane, as 10 before the wafer 15 drops freely to the stack 21, the latter is moved at a distance from the cutting plane which is greater than the height of the bearing surface 16, in the direction of moving the bread 3, in addition to the thickness of the slice 15 concerned. Thus, the slice 15, which has just been cut, can fall freely to the stack 21 without coming into contact with the side wall of the receiving compartment 4 at the height of the escape formed by the surface 17. Even if a wafer 15 is moved laterally towards the bearing surface 16, following the friction that may be present between the blade 8 and this wafer 15, a free fall of the wafer 15 is obtained by the presence of the wafer 15. flaring of the receiving compartment 4 formed by the sliding surface 17. In particular, the wafer 15 drops freely in the space between the lower level of the bearing surface 16 and the upper side of the stack 21.
De cette façon le pain 3 est déplacé vers le compartiment de réception 4 suivant des pas discrets correspondant, de préférence, à l'épaisseur des tranches 15 en maintenant l'extrémité supérieure du pain par le poussoir 13 jusqu'à sa découpe complète . L'empilage 21, formé par le pain 3 découpé, est ensuite transporté dans la direction de déplacement vers le compartiment de chargement 1, en entraînant le support mobile 6, afin de pouvoir le récupérer à l'état découpé. Il va de soi qu'avant que le pain coupé 3 est enlevé du compartiment de chargement 1, son extrémité supérieure est libérée des crochets 14. In this way the bread 3 is moved to the receiving compartment 4 in discrete steps, preferably corresponding to the thickness of the slices 15 by maintaining the upper end of the bread by the pusher 13 to its complete cut. The stack 21, formed by the cut bread 3, is then transported in the direction of movement to the load compartment 1, driving the mobile support 6, in order to recover it in the cut state. It goes without saying that before the cut bread 3 is removed from the loading compartment 1, its upper end is released from the hooks 14.
Lors du déplacement ascendant du pain coupé 3 vers le compartiment de chargement 1, la zone 20 du pain est, avantageusement, guidée par la partie supérieure de la surface de glissement 17 adjacente à la surface d'appui 16.  During the upward movement of the cut bread 3 towards the loading compartment 1, the area 20 of the bread is advantageously guided by the upper part of the sliding surface 17 adjacent to the bearing surface 16.
Dans les figures 13 à 16 une forme de réalisation alternative de la machine, suivant l'invention, est représentée. Cette forme de réalisation se distingue principalement de la forme de réalisation de l'invention représentée aux figures 8 à 12 par le fait que la paroi latérale de la gouttière susdite, ou, en particulier, la paroi latérale du compartiment de chargement 1 et du compartiment de réception 4 est légèrement inclinée par rapport à la verticale. Ainsi, lorsqu'on place un pain 3 dans le compartiment de chargement 1, comme illustré dans la figure 13, ce pain 3 se pose automatiquement sur la surface de support 2 et contre la surface de guidage 11.  In Figures 13 to 16 an alternative embodiment of the machine according to the invention is shown. This embodiment differs mainly from the embodiment of the invention shown in Figures 8 to 12 in that the side wall of said gutter, or, in particular, the side wall of the load compartment 1 and the compartment reception 4 is slightly inclined relative to the vertical. Thus, when a bread 3 is placed in the loading compartment 1, as illustrated in FIG. 13, this bread 3 is automatically placed on the support surface 2 and against the guide surface 11.
Cette paroi, comprenant la surface de guidage 1 1 et la deuxième partie 18 de la surface de glissement, est, par exemple, inclinée d'un angle a inférieur à 30° ou à 15° par rapport à la direction verticale. De préférence, cet angle a est inférieur à 10° ou de l'ordre de 5°, par exemple 3°.  This wall, comprising the guide surface January 1 and the second portion 18 of the sliding surface, is, for example, inclined at an angle less than 30 ° or 15 ° relative to the vertical direction. Preferably, this angle a is less than 10 ° or of the order of 5 °, for example 3 °.
Ladite gouttière ne présente, par conséquent, pas nécessairement une section transversale qui a l'allure d'un U, mais peut également avoir une section en V.  Said gutter therefore does not necessarily have a cross section that looks like a U, but may also have a V-shaped section.
Suite à l'inclinaison de la surface de guidage 11 et de la partie inférieure 18 de la surface de glissement 17, au moins certaines des tranches découpées contenues dans l'empilage 21 peuvent venir en contact avec cette partie inférieure 18 de la surface de glissement 17, comme illustré dans la figure 15.  Following the inclination of the guide surface 11 and the lower part 18 of the sliding surface 17, at least some of the cut edges contained in the stack 21 can come into contact with this lower part 18 of the sliding surface. 17, as shown in Figure 15.
Après que le pain ait été complètement coupé en tranches 15, celui-ci est remonté vers le compartiment de chargement 1 par le mouvement ascendant du support mobile 6. Lors de ce déplacement du pain découpé, l'empilage 21 des tranches After the bread has been completely cut into slices 15, it is reassembled to the loading compartment 1 by the upward movement of the mobile support 6. During this displacement of the cut bread, the stack 21 of the slices
15 est guidé par la surface de glissement 17 et un accrochement des tranches 15, par exemple, au bord inférieur de la surface de guidage 11 est évité. Ce déplacement ascendant de l'empilage 21 est illustré dans la figure 16. 15 is guided by the sliding surface 17 and an attachment of the slices 15, for example, to the lower edge of the guide surface 11 is avoided. This upward movement of the stack 21 is illustrated in FIG.
Dans encore une autre forme de réalisation de l'invention, seulement la surface de guidage 11 est inclinée par rapport à la verticale, comme décrit ci-dessus, tandis que la surface d'appui 16 et la deuxième partie 18 de la surface de glissement 17 s'étendent sensiblement verticalement. Dans les différentes formes de réalisation de l'invention décrites ci- dessus, la fente 5 dans la surface de support 2 est, avantageusement fermée quand la lame 8 n'est pas présente dans cette fente 5. A cet effet, la machine, suivant l'invention, comprend, de préférence, au moins un organe de fermeture mobile qui permet de fermer la partie libre de la fente 5 au fur et à mesure de l'avancement ou du reculement du dispositif de coupe 7 à travers la fente 5. Ainsi, le pain 3 peut glisser sur la surface de cet organe de fermeture lors de son déplacement entre les compartiments suivant la direction de déplacement du pain. In yet another embodiment of the invention, only the guide surface 11 is inclined with respect to the vertical, as described above, while the bearing surface 16 and the second portion 18 of the sliding surface 17 extend substantially vertically. In the various embodiments of the invention described above, the slot 5 in the support surface 2 is advantageously closed when the blade 8 is not present in this slot 5. For this purpose, the machine, following the invention preferably comprises at least one movable closing member which makes it possible to close the free part of the slot 5 as the cutting device advances or retreats through the slot 5. Thus, the bread 3 can slide on the surface of this closure member during its movement between the compartments in the direction of movement of the bread.
L'invention n'est bien entendu pas limitée à la forme de réalisation décrite ci-dessus et représentée aux figures annexées, mais bien d'autres variantes pourraient être envisagées sans sortir du cadre de l'invention.  The invention is of course not limited to the embodiment described above and shown in the accompanying figures, but many other variants could be envisaged without departing from the scope of the invention.
Ainsi, il n'est pas essentiel que la surface de glissement 17 présente une deuxième partie 18, mais elle peut seulement comprendre qu'une première partie inclinée qui est adjacente à la surface d'appui 16.  Thus, it is not essential that the sliding surface 17 has a second portion 18, but it can only include a first inclined portion which is adjacent to the bearing surface 16.
La hauteur de la surface d'appui 16, suivant la direction de déplacement du pain, est de préférence de l'ordre de l'épaisseur d'une tranche 15, mais elle peut être inférieure ou supérieure à cette épaisseur.  The height of the bearing surface 16, in the direction of movement of the bread, is preferably of the order of the thickness of a wafer 15, but it may be less than or greater than this thickness.
Dans les figures 8 et 13, le support mobile 6 est positionné dans le compartiment de réception 4 lorsqu'un pain 3 à couper est introduit dans la machine, suivant l'invention. Il est clair qu'il est également possible que ce support mobile 6 est déplacé jusque dans le compartiment de chargement 1 avant qu'un pain à découper est introduit.  In Figures 8 and 13, the movable support 6 is positioned in the receiving compartment 4 when a bread 3 to be cut is introduced into the machine according to the invention. It is clear that it is also possible that this mobile support 6 is moved into the load compartment 1 before a piece of bread is introduced.
Ce support mobile 6 peut éventuellement présenter une surface supérieure creuse, dans laquelle l'extrémité inférieure du pain peut être logée.  This mobile support 6 may optionally have a hollow upper surface, in which the lower end of the bread can be accommodated.
La surface de support 2 est de préférence tout droite, mais elle peut également être courbée. Il est, par exemple, possible que la partie de la surface de support 2, qui s'étend dans le compartiment de réception, constitue une surface d'appui adjacente à la première fente 5. Cette surface d'appui est, par exemple, analogue à celle prévue dans le prolongement de la surface de guidage 11 et est avantageusement également suivie par une surface de glissement formant un évasement du compartiment de réception 4. Ceci permet une chute libre d'une tranche 15 coupée du pain 3 vers la partie déjà coupée du pain. Comme décrit ci-dessus, l'invention concerne une machine à couper automatiquement un pain, en particulier une trancheuse à pain, présentant une surface de support 2 pour le pain 3, qui est de préférence légèrement inclinée par rapport à la verticale. Cette surface de support 2 est, en particulier, inclinée d'un angle inférieur à 45° par rapport à une direction verticale et de préférence inférieur à 30° ou à 15° par rapport à la direction verticale. Néanmoins, il est également possible que cette surface de support 2 s'étend essentiellement verticalement. The support surface 2 is preferably straight, but it can also be curved. For example, it is possible for the portion of the support surface 2, which extends into the receiving compartment, to constitute a bearing surface adjacent to the first slot 5. This bearing surface is, for example, similar to that provided in the extension of the guide surface 11 and is advantageously also followed by a sliding surface forming a flaring of the receiving compartment 4. This allows a free fall of a slice 15 cut bread 3 to the part already cut bread. As described above, the invention relates to a machine for automatically cutting a bread, in particular a bread slicer, having a support surface 2 for the bread 3, which is preferably slightly inclined relative to the vertical. This support surface 2 is, in particular, inclined at an angle less than 45 ° relative to a vertical direction and preferably less than 30 ° or 15 ° relative to the vertical direction. Nevertheless, it is also possible that this support surface 2 extends essentially vertically.
