Description

L'invention concerne une machine à découper automatiquement en tranches un pain ou une denrée analogue. Cette machine comprend un compartiment de chargement, qui est connecté à un compartiment de réception, et une surface de support pour le pain s'étendant dans lesdits compartiments. Cette surface définie une direction de déplacement du pain parallèlement à la surface de support, suivant laquelle le pain est transporté entre les deux compartiments. La machine est également pourvue d'un dispositif de coupe pour couper des tranches du pain, lorsque celui-ci est déplacé entre les deux compartiments. A cet effet, une fente est prévue dans la surface de support entre le compartiment de chargement et le compartiment de réception s'étendant essentiellement transversalement par rapport à la direction de déplacement. Le dispositif peut se déplacer à travers cette fente suivant un mouvement de va-et-vient selon la direction longitudinale de la fente pour couper des tranches du pain.The invention relates to a slicing machine automatically slices a bread or a similar commodity. This machine includes a loading compartment, which is connected to a receiving compartment, and a support surface for the bread extending into said compartments. This surface defines a direction of movement of the bread parallel to the support surface, according to which the bread is transported between the two compartments. The machine is also provided with a cutting device for cutting slices of bread when it is moved between the two compartments. For this purpose, a slot is provided in the support surface between the loading compartment and the receiving compartment extending substantially transversely to the direction of movement. The device can move through this slot reciprocatingly along the longitudinal direction of the slot to cut slices of bread.

Une telle machine à découper un pain est, par exemple, décrite dans les documents DE 4431808 et DE 9310092 .Such a bread-cutting machine is, for example, described in the documents DE 4431808 and DE 9310092 .

Un problème important qui se manifeste dans de telles machines est que, lors du déplacement du pain le long de la surface de support suivant ladite direction de déplacement, le pain traverse la hauteur de la fente, qui est prévue pour permettre le passage du dispositif de coupe. Ainsi, il arrive souvent que le déplacement du pain est dérangé par la présence de cette fente parce que le pain ou les tranches du pain, s'accrochent à l'un des bords longitudinaux de la fente au moment du franchissement de la fente.An important problem that manifests itself in such machines is that, when moving the bread along the support surface in said direction of travel, the bread passes through the height of the slot, which is provided to allow the passage of the chopped off. Thus, it often happens that the displacement of the bread is disturbed by the presence of this slot because the bread or slices of the bread, cling to one of the longitudinal edges of the slot at the time of crossing the slot.

Dans les trancheuses à pain dans lesquelles le pain est transporté horizontalement dans un seul sens, la partie de la surface de support qui s'étend en-dessous la partie coupé du pain est généralement positionnée quelque peu plus bas que la partie de cette surface dans le compartiment dans lequel le pain à couper est introduit. Ainsi, les mêmes problèmes se produisent pour de telles trancheuses lorsqu'on souhaite d'inverser le déplacement du pain après sa découpe.In bread slicers in which the bread is transported horizontally in one direction, the portion of the support surface that extends below the cut portion of the bread is generally positioned somewhat lower than the portion of that surface in the compartment in which the bread to be cut is introduced. Thus, the same problems occur for such slicers when it is desired to reverse the movement of the bread after cutting.

Le document DE 10 2013 203990 A1 divulgue une trancheuse avec un organe de fermeture pour couvrir partiellement la fente. Cet organe de fermeture est formé par la partie limite déformable de la surface de support et ne permet pas de fermer la fente sur toute la largeur de celle-ci.The document DE 10 2013 203990 A1 discloses a slicer with a closure member to partially cover the slit. This closure member is formed by the deformable limit portion of the support surface and does not close the slot over the entire width thereof.

L'invention veut remédier à ce problème en proposant une machine dans laquelle le pain et/ou les tranches du pain sont transportés en regard de la fente sans aucune entrave et sans être gêné par la présence de la fente.The invention seeks to remedy this problem by proposing a machine in which the bread and / or bread slices are transported opposite the slot without any hindrance and without being bothered by the presence of the slot.

A cet effet, la machine, suivant l'invention, comprend au moins un organe de fermeture mobile permettant de fermer la partie libre de la fente au fur et à mesure de l'avancement ou du reculement du dispositif de coupe à travers la fente.For this purpose, the machine according to the invention comprises at least one movable closure member for closing the free portion of the slot as the cutting device advances or retreats through the slot.

Avantageusement, l'organe de fermeture coopère avec le dispositif de coupe de manière à synchroniser le mouvement de l'organe de fermeture et du dispositif de coupe.Advantageously, the closure member cooperates with the cutting device so as to synchronize the movement of the closure member and the cutting device.

Suivant une forme de réalisation particulière de l'invention, la surface de l'organe de fermeture est bombée dans la direction de déplacement du pain et du côté des compartiments susdits, de telle manière à ce que cette surface s'étend à travers la fente. Ainsi, le pain peut glisser sur cette surface bombée lors de son déplacement entre les compartiments suivant la direction de déplacement du pain.According to a particular embodiment of the invention, the surface of the closure member is curved in the direction of movement of the bread and the side of said compartments, so that this surface extends through the slot . Thus, the bread can slide on this curved surface during its movement between the compartments in the direction of movement of the bread.

La surface bombée susdite s'étend, de préférence, quelque peu au-delà de la surface de support lorsque l'organe de fermeture ferme la partie libre de la fente.The aforesaid curved surface preferably extends somewhat beyond the support surface when the closure member closes the free portion of the slot.

Suivant une forme de réalisation intéressante de l'invention, au moins une partie de l'organe de fermeture, lorsque cette partie ferme la fente, s'étend derrière la surface de support par rapport aux compartiments.According to an advantageous embodiment of the invention, at least a part of the closure member, when this part closes the slot, extends behind the support surface relative to the compartments.

Suivant une forme de réalisation préférentielle de l'invention, l'organe de fermeture comprend un cylindre, dont le diamètre est supérieur à la hauteur de la fente, qui est monté de manière rotative autour de son axe. L'axe de ce cylindre s'étend sensiblement parallèlement à la direction longitudinale de la fente et derrière la surface de support par rapport aux compartiments. Le cylindre est entraîné autour de son axe suivant un mouvement de va-et-vient, de sorte que, lorsque le dispositif de coupe est retiré de la fente, celle-ci est fermée par la surface du cylindre, et de sorte qu'un évidement prévu dans le cylindre pour le dispositif de coupe est déplacé en regard de la fente au fur et à mesure de l'avancement ou du reculement du dispositif de coupe dans la fente pour maintenir la partie de la fente, située latéralement par rapport au dispositif de coupe, fermée.According to a preferred embodiment of the invention, the closure member comprises a cylinder, whose diameter is greater than the height of the slot, which is rotatably mounted about its axis. The axis of this cylinder extends substantially parallel to the longitudinal direction of the slot and behind the support surface relative to the compartments. The cylinder is driven about its axis in a reciprocating manner, so that when the cutting device is removed from the slot, the slot is closed by the surface of the cylinder, and so that recess provided in the cylinder for the cutting device is moved opposite the slot as the cutting device advances or retracts into the slot to maintain the portion of the slot, located laterally with respect to the device cutting, closed.

Dans cette forme de réalisation de la machine, suivant l'invention, le dispositif de coupe se déplace, de préférence, selon un plan qui comprend l'axe du cylindre.In this embodiment of the machine, according to the invention, the cutting device preferably moves in a plane which comprises the axis of the cylinder.

Suivant une forme de réalisation particulière de l'invention, l'évidement susdit est formé par une découpe dans le cylindre. Cette découpe est délimitée à la surface de ce cylindre, d'une part, par une ligne droite s'étendant parallèlement à l'axe du cylindre et, d'autre part, par une ligne hélicoïdale.According to a particular embodiment of the invention, the aforesaid recess is formed by a cut in the cylinder. This cutout is delimited on the surface of this cylinder, on the one hand, by a straight line extending parallel to the axis of the cylinder and, on the other hand, by a helical line.

Dans une forme de réalisation alternative de la machine, suivant l'invention, l'organe de fermeture comprend une bande dont la largeur est au moins égale à la hauteur de la fente. Cette bande peut être déplacée suivant un mouvement de va-et-vient selon la direction longitudinale de la fente en regard de celle-ci pour la fermer au fur et à mesure de l'avancement ou du reculement du dispositif de coupe dans la fente, afin de maintenir la partie de la fente, située latéralement par rapport au dispositif de coupe, à l'état fermé.In an alternative embodiment of the machine, according to the invention, the closure member comprises a band whose width is at least equal to the height of the slot. This band can be moved reciprocatingly in the longitudinal direction of the slot opposite it to close as the progress or retreat of the cutting device in the slot, to maintain the portion of the slot, located laterally relative to the cutting device, in the closed state.

D'une manière intéressante, ladite bande est enroulée et déroulée à partir d'un rouleau formé de cette bande, suivant un mouvement de va-et-vient pour fermer la fente au fur et à mesure de l'avancement ou du reculement du dispositif de coupe dans la fente.Interestingly, said strip is wound and unrolled from a roll formed of this band, reciprocatingly to close the slot as the advancement or retreat of the device cutting in the slot.

D'une manière particulière, la bande est incurvée suivant sa direction transversale, de sorte que la partie déroulée, s'étendant en regard de la fente, devient rigide.In a particular way, the strip is curved in its transverse direction, so that the unrolled part, extending opposite the slot, becomes rigid.

L'invention est de préférence appliquée dans une machine dont ladite surface de support pour le pain est inclinée d'un angle compris entre 0° et 20° par rapport à la verticale.The invention is preferably applied in a machine where said support surface for the bread is inclined at an angle between 0 ° and 20 ° relative to the vertical.

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 d'une trancheuse. Ce compartiment présente une surface de support pour le pain présentant une plaque qui s'étend sensiblement verticalement ou qui est inclinée d'un angle α inférieur à 30°, en particulier, inférieur à 20°, par rapport à la verticale.To cut the bread into slices, it is placed in a loading compartment of a slicer. This compartment has a support surface for the bread having a plate which extends substantially vertically or which is inclined at an angle α less than 30 °, in particular less than 20 °, with respect to the vertical.

Cette surface de support s'étend jusque dans un compartiment de réception et présente une fente qui délimite ce compartiment de réception par rapport au compartiment de chargement.This support surface extends into a receiving compartment and has a slot which defines this receiving compartment with respect to the loading compartment.

La machine présente également un support mobile pour le pain s'étendant, de préférence, transversalement par rapport à la surface de support. Ce support mobile est entraîné, par exemple, par un moteur électrique pour transporter le pain du compartiment de chargement vers le compartiment de réception et vice-versa.The machine also has a movable support for the bread extending preferably transversely to the support surface. This mobile support is driven, for example, by an electric motor to transport the bread from the loading compartment to the receiving compartment and vice versa.

Pour couper le pain en tranches, celui-ci est placé avec le côté, qui forme le fond du pain, contre la surface de support dans le compartiment de chargement pendant qu'il est supporté par le support mobile. Le pain subit alors un déplacement descendant ou ascendant vers le compartiment de réception pendant qu'il est guidé par la surface de support suivant un mouvement correspondant du support mobile. Ainsi, cette surface de support définie la direction de déplacement du pain, suivant laquelle le pain et le support mobile sont déplacés.To cut the bread into slices, it is placed with the side, which forms the bottom of the bread, against the support surface in the loading compartment while it is supported by the mobile support. The bread is then moved downward or upward toward the receiving compartment while being guided by the support surface following a corresponding movement of the movable support. Thus, this support surface defines the direction of movement of the bread, according to which the bread and the movable support are moved.

Lors du mouvement du pain, celui-ci est coupé en tranches au moyen d'un dispositif de coupe comprenant une lame de coupe qui se déplace à travers le pain suivant une direction horizontale ou transversale par rapport à la direction de déplacement. Après chaque passage de la lame de coupe, le pain est avancé d'une distance correspondant à l'épaisseur d'une tranche avant de couper une tranche suivante. Ainsi, un pain coupé est obtenu dont les tranches sont empilées l'une sur l'autre entre les deux extrémités opposées du pain.During the movement of the bread, it is sliced by means of a cutting device comprising a cutting blade which moves through the bread in a direction horizontal or transverse to the direction of movement. After each passage of the cutting blade, the bread is advanced a distance corresponding to the thickness of a slice before cutting a next slice. Thus, a cut bread is obtained whose slices are stacked one on the other between the two opposite ends of the bread.

Une telle trancheuse est, par exemple, décrite dans les documents DE 4431808 et DE 9310092 .Such a slicer is, for example, described in the documents DE 4431808 and DE 9310092 .

Les figures 1 à 5 représentent schématiquement la surface de support, l'organe de fermeture et le dispositif de coupe d'une machine, suivant une première forme de réalisation de l'invention. Pour la clarté des figures, d'autres parties, comme par exemple le châssis de la machine et le support mobile, ne sont pas montrés.The Figures 1 to 5 schematically represent the support surface, the closure member and the cutting device of a machine, according to a first embodiment of the invention. For the sake of clarity of the figures, other parts, such as for example the chassis of the machine and the mobile support, are not shown.

La machine à découper du pain comprend un compartiment de chargement 1 qui est connecté à un compartiment de réception 2. Une surface de support 3 s'étend dans ces deux compartiments 1 et 2.The bread slicing machine comprises a loading compartment 1 which is connected to a receiving compartment 2. A support surface 3 extends into these two compartments 1 and 2.

Pour couper un pain 4 en tranches, celui-ci est placé dans le compartiment de chargement 1 contre la surface de support 3. Ensuite, le pain 4 est transporté de ce compartiment 1 vers le compartiment de réception 2. Lors de ce déplacement, le pain 4 glisse contre la surface de support 3, présentant de préférence une surface plane et lisse. Ainsi, cette surface de support 3 définie une direction de déplacement du pain 4 qui s'étend parallèlement à la surface de support 3 de l'un des compartiments vers l'autre compartiment.To cut a slice of bread 4, it is placed in the loading compartment 1 against the support surface 3. Next, the bread 4 is transported from this compartment 1 to the receiving compartment 2. During this movement, the bread 4 slides against the support surface 3, preferably having a flat and smooth surface. Thus, this support surface 3 defines a direction of movement of the bread 4 which extends parallel to the support surface 3 of one of the compartments to the other compartment.

Entre les deux compartiments 1 et 2, la surface de support 3 présente une fente 5 qui s'étend essentiellement transversalement par rapport à la direction de déplacement susdite. Ainsi, le pain traverse cette fente 5 lors de son déplacement entre les deux compartiments 1 et 2.Between the two compartments 1 and 2, the support surface 3 has a slot 5 which extends substantially transversely with respect to the direction of displacement aforesaid. Thus, the bread passes through this slot 5 during its movement between the two compartments 1 and 2.

Un dispositif de coupe 6 permet de couper des tranches du pain 4 lorsque celui-ci est déplacé entre les compartiments 1 et 2 en regard de la fente 5.A cutting device 6 makes it possible to cut slices of the bread 4 when the latter is moved between the compartments 1 and 2 opposite the slot 5.

Ce dispositif de coupe 6 comprend une lame de coupe circulaire 7 qui est entraînée autour de son axe central. La lame de coupe 7 est montée sur l'extrémité d'un bras 8, qui est également entraîné pour déplacer la lame 7 à travers la fente 5. Lorsque le pain 4 est positionné devant la fente 5, la lame 7 peut alors subir un mouvement à travers le pain 4 et la fente 5 pour couper une tranche du pain 4.This cutting device 6 comprises a circular cutting blade 7 which is driven around its central axis. The cutting blade 7 is mounted on the end of an arm 8, which is also driven to move the blade 7 through the slot 5. When the bread 4 is positioned in front of the slot 5, the blade 7 can then undergo a move through bread 4 and slot 5 to cut a slice of bread 4.

Pour couper un pain 4 en tranches, celui-ci est avancé sur des pas successifs correspondant à l'épaisseur d'une tranche à couper. Après chaque avancement, le dispositif de coupe 6, en particulier la lame 7, est déplacé suivant un mouvement de va-et-vient à travers le pain 4 et la fente 5 pour découper une tranche suivante, comme indiqué par les flèches 9 et 10.To cut a slice of bread 4, it is advanced on successive steps corresponding to the thickness of a slice to cut. After each advance, the cutting device 6, in particular the blade 7, is moved back and forth through the bread 4 and the slot 5 to cut a next slice, as indicated by the arrows 9 and 10. .

Dans les figures 2 à 4 le pain 4, qui se trouve en regard de la fente 5, n'est, pour la clarté des figures, pas représenté.In the Figures 2 to 4 the bread 4, which is opposite the slot 5, is not shown for clarity of the figures.

Néanmoins, la surface de support 3 peut s'étendre, par exemple, suivant un plan horizontal ou incliné par rapport à l'horizontale, dans la forme de réalisation de l'invention, qui est représentée aux figures 1 à 5, la surface de support 3 est, de préférence, inclinée d'un angle α compris entre 0° et 20° par rapport à la verticale.Nevertheless, the support surface 3 may extend, for example, along a horizontal plane or inclined with respect to the horizontal, in the embodiment of the invention, which is shown in FIGS. Figures 1 to 5 , the support surface 3 is preferably inclined at an angle α between 0 ° and 20 ° relative to the vertical.

Ainsi, la machine, suivant la première forme de réalisation de l'invention, comprend un support mobile pour le pain 4 qui est déplaçable suivant ladite direction de déplacement du pain pour soutenir le pain 4. Ce support mobile n'est pas représenté aux figures annexées, mais est connu par l'homme du métier.Thus, the machine, according to the first embodiment of the invention, comprises a movable support for the bread 4 which is movable along said direction of movement of the bread to support the bread 4. This mobile support is not shown in FIGS. attached, but is known to those skilled in the art.

Lorsque le pain à couper en tranches est placé dans le compartiment de chargement 1, il est posé sur le support mobile, qui se trouve à ce moment dans ce compartiment 1. Lors de la découpe du pain 4 en tranches, le support mobile est déplacé suivant la direction de déplacement du pain vers le bas du deuxième compartiment. Comme expliqué plus haut, ce déplacement est fait à des pas successifs correspondant à l'épaisseur d'une tranche. Après la découpe complète du pain, le support mobile est, de préférence, remonté vers le compartiment de chargement 1 pour transporter le pain vers ce compartiment 1, afin de pouvoir enlever le pain coupé de la machine.When the sliced bread is placed in the loading compartment 1, it is placed on the mobile support, which is at this time in this compartment 1. When cutting the bread 4 into slices, the mobile support is moved following the direction of movement of the bread towards the bottom of the second compartment. As explained above, this displacement is made in successive steps corresponding to the thickness of a slice. After complete cutting of the bread, the mobile support is preferably reassembled to the load compartment 1 to transport the bread to the compartment 1, in order to remove the cut bread from the machine.

Pour s'assurer que le pain 4 peut glisser sur la surface de support 3, lorsque celui-ci est déplacé entre les deux compartiments 1 et 2, la machine, suivant l'invention, comprend un organe de fermeture mobile 11 qui permet de fermer la fente 5 susdite à l'endroit où la lame de coupe 7 n'est pas présente dans la fente 5. De cette façon, cet organe de fermeture 11 permet de fermer la partie libre de la fente 5 au fur et à mesure de l'avancement of du reculement du dispositif de coupe 6, en particulier la lame 7, à travers la fente 5.To ensure that the bread 4 can slide on the support surface 3, when the latter is moved between the two compartments 1 and 2, the machine according to the invention comprises a movable closing member 11 which allows to close the slot 5 above where the cutting blade 7 is not present in the slot 5. In this way, this closure member 11 closes the free portion of the slot 5 as the progress of the retraction of the cutting device 6, in particular the blade 7, through the slot 5.

L'organe de fermeture 11 est formé par un cylindre 12, dont l'axe 13 s'étend parallèlement à la direction longitudinale de la fente 5. Le diamètre du cylindre 12 est supérieur à la hauteur de la fente 5 et il est monté derrière la surface de support 3 par rapport aux compartiments 1 et 2 de manière telle à ce que la surface du cylindre 12 s'étend, de préférence quelque peu à travers la fente 5. Ainsi, cette surface est bombée dans la direction de déplacement du pain et du côté des compartiments 1 et 2.The closure member 11 is formed by a cylinder 12 whose axis 13 extends parallel to the longitudinal direction of the slot 5. The diameter of the cylinder 12 is greater than the height of the slot 5 and is mounted behind the support surface 3 with respect to the compartments 1 and 2 so that the surface of the cylinder 12 extends, preferably somewhat through the slot 5. Thus, this surface is convex in the direction of movement of the bread and on the side of compartments 1 and 2.

Lorsqu'une tranche du pain est coupé, la lame 7 du dispositif de coupe 6 se déplace à travers la fente 5 et le long de celle-ci. Pour permettre ce mouvement de la lame 7, le cylindre 12 présente un évidement 14 pour la lame 7 et est monté de manière rotative autour de son axe 13.When a slice of the bread is cut, the blade 7 of the cutting device 6 moves through the slot 5 and along it. To allow this movement of the blade 7, the cylinder 12 has a recess 14 for the blade 7 and is rotatably mounted about its axis 13.

Lorsque la lame 7 ne s'étend pas dans la fente 5, une partie de la surface du cylindre, qui ne présente pas d'évidement 14, est positionnée dans la fente 5, comme représenté aux figures 1, 5, 6 et 9. Dans cette position du cylindre 12, un pain 4 peut être déplacé suivant ladite direction de déplacement sur la surface de support 3 et traverser la hauteur de la fente 5 sans être gêné par la présence de la fente 5. Le pain glisse alors sur la surface bombée du cylindre 12.When the blade 7 does not extend into the slot 5, a portion of the surface of the cylinder, which does not have a recess 14, is positioned in the slot 5, as shown in FIGS. Figures 1, 5 , 6 and 9 . In this position of the cylinder 12, a roll 4 can be moved in said direction of displacement on the support surface 3 and pass through the height of the slot 5 without being impeded by the presence of the slot 5. The bread then slides on the surface curved cylinder 12.

Au fur et à mesure que la lame 7 entre l'espace dans la fente 5 pour découper une tranche, le cylindre 12 est entraîné autour de son axe 13, de sorte que la fente 5 est partiellement ouverte en positionnant l'évidement 14 en regard de la fente 5 à l'endroit où la lame 7 avance dans la fente 5 pour permettre le passage de cette dernière. Ceci est montré schématiquement aux figures 2, 7 et 10.As the blade 7 enters the space in the slot 5 to cut a wafer, the cylinder 12 is driven about its axis 13, so that the slot 5 is partially open by positioning the recess 14 next to of the slot 5 at the place where the blade 7 advances in the slot 5 to allow the passage of the latter. This is schematically shown to figures 2 , 7 and 10 .

L'évidement 14 est formé par une découpe dans le cylindre 12, qui est délimitée à la surface de ce cylindre, d'une part, par une ligne droite 15 s'étendant parallèlement à l'axe du cylindre et, d'autre part, par une ligne hélicoïdale 16. Ainsi, à l'endroit où l'évidement 14 est positionné en regard de la fente 5, la lame 7 peut s'étendre à travers cet évidement 14.The recess 14 is formed by a cut in the cylinder 12, which is delimited on the surface of this cylinder, on the one hand, by a straight line 15 extending parallel to the axis of the cylinder and, on the other hand by a helical line 16. Thus, where the recess 14 is positioned facing the slot 5, the blade 7 can extend through this recess 14.

A cet effet, le volume de cet évidement 14 est, de préférence, supérieur à la moitié du cylindre 12 le long de la longueur de l'évidement 14 suivant l'axe 13 du cylindre 12. La distance entre la ligne droite 15 et la ligne hélicoïdale 16 diminue d'une distance qui est sensiblement égale au diamètre du cylindre 12 jusqu'à une distance qui est au moins égale à la hauteur de la fente 5.For this purpose, the volume of this recess 14 is preferably greater than half of the cylinder 12 along the length of the recess 14 following the axis 13 of the cylinder 12. The distance between the straight line 15 and the helical line 16 decreases by a distance that is substantially equal to the diameter of the cylinder 12 to a distance that is at least equal to the height of the slot 5.

Lors de l'avancement de la lame 7 le long de la fente 5, le cylindre 12 tourne autour de son axe 13, comme indiqué par la flèche 17, pour ouvrir la fente 5 jusqu'à ce que la lame 7 a traversé presque complètement la longueur de la fente 5 ou au moins l'endroit correspondant à l'espace occupé par le pain 4 devant la fente 5. Par la rotation du cylindre 12, la ligne hélicoïdale 16 est maintenue à une petite distance devant la lame 7.During the advancement of the blade 7 along the slot 5, the cylinder 12 rotates about its axis 13, as indicated by the arrow 17, to open the slot 5 until the blade 7 has passed through almost completely. the length of the slot 5 or at least the place corresponding to the space occupied by the bread 4 in front of the slot 5. By the rotation of the cylinder 12, the helical line 16 is kept at a small distance in front of the blade 7.

Après que la lame 7 ait traversé la fente 5 de telle manière, le mouvement de la lame 7 est inversé et la lame 7 est retirée de la fente 5 comme illustré aux figures 4 et 5. Lorsque l'on commence le retrait de la lame 7, la direction de rotation du cylindre 12 autour de son axe 13 est également inversé. Ainsi, au fur et à mesure du reculement de la lame 7 dans la fente 5 la partie de celle-ci, qui est libérée par la lame 7 et située latéralement par rapport à la lame 7, est fermée par la surface du cylindre 12.After the blade 7 has passed through the slot 5 in such a way, the movement of the blade 7 is reversed and the blade 7 is removed from the slot 5 as illustrated in FIGS. Figures 4 and 5 . When the blade 7 is started to be withdrawn, the direction of rotation of the cylinder 12 about its axis 13 is also reversed. Thus, as the blade 7 retracts into the slot 5, the portion thereof, which is released by the blade 7 and located laterally relative to the blade 7, is closed by the surface of the cylinder 12.

Pour couper des tranches du pain 4, lorsque celui-ci se déplace du compartiment de chargement 1 vers le compartiment de réception 2, la lame de coupe 7 subit un mouvement de va-et-vient le long de la fente 5 par l'entraînement du bras 9 suivant la direction des flèches 9 et 10. Lors de ce mouvement de va-et-vient la lame 7 se déplace selon un plan qui comprend l'axe 13 du cylindre 12.To cut slices of the bread 4, as it moves from the loading compartment 1 to the receiving compartment 2, the cutting blade 7 is reciprocated along the slit 5 by the drive of the arm 9 in the direction of the arrows 9 and 10. During this movement back and forth the blade 7 moves in a plane which comprises the axis 13 of the cylinder 12.

L'organe de fermeture 11, formé par le cylindre 12, coopère donc avec le dispositif de coupe 6, qui comprend la lame 7, de manière à synchroniser le mouvement du cylindre 12 et de la lame 7. A cet effet, des moyens de synchronisation sont prévus qui comprennent, par exemple, un système électronique qui commande le moteur entraînant le cylindre 12 autour de son axe en fonction du mouvement de va-et-vient du bras 8, qui fait partie du dispositif de coupe 6.The closure member 11, formed by the cylinder 12, thus cooperates with the cutting device 6, which comprises the blade 7, so as to synchronize the movement of the cylinder 12 and the blade 7. For this purpose, means of synchronization are provided which include, for example, an electronic system which controls the motor driving the cylinder 12 about its axis as a function of the back and forth movement of the arm 8, which is part of the cutting device 6.

Des moyens de synchronisation peuvent, alternativement, comprendre une connexion mécanique entre l'organe de fermeture 11 et le dispositif de coupe 6, de sorte que le mouvement du cylindre 12 est entrainé par le déplacement du bras 8.Synchronization means may, alternatively, comprise a mechanical connection between the closure member 11 and the cutting device 6, so that the movement of the cylinder 12 is caused by the displacement of the arm 8.

Une deuxième forme de réalisation de la machine, suivant l'invention, est différente de la première forme de réalisation en ce que l'organe de fermeture 11 est formé par une bande mobile 18, comme représentée aux figures 11 à 15, au lieu d'un cylindre 12.A second embodiment of the machine according to the invention is different from the first embodiment in that the closure member 11 is formed by a moving band 18, as shown in Figures 11 to 15 , instead of a cylinder 12.

Cette bande 18 peut être déplacée suivant un mouvement de va-et-vient selon la direction longitudinale de la fente 5 et en regard de celle-ci pour la fermer au fur et à mesure de l'avancement ou du reculement de la lame 7 dans la fente 5.This band 18 can be moved reciprocatingly in the longitudinal direction of the slot 5 and facing it to close as the advancement or retreat of the blade 7 in the slot 5.

La largeur de cette bande 18 est au moins égale à la hauteur de la fente pour permettre de fermer celle-ci.The width of this band 18 is at least equal to the height of the slot to allow closing thereof.

La bande 18 est enroulée et déroulée à partir d'un rouleau 19 formé de cette bande 18, qui est positionné latéralement à côté de la fente 5 et de la surface de support 3. Ainsi, la bande 18 est déroulée et enroulée, suivant un mouvement de va-et-vient pour fermer la fente 5 au fur et à mesure de l'avancement ou du retrait de la lame 7 dans la fente 5.The strip 18 is wound and unrolled from a roll 19 formed of this strip 18, which is positioned laterally next to the slot 5 and the support surface 3. Thus, the strip 18 is unwound and wound, following a reciprocating movement to close the slot 5 as the blade 7 is advanced or withdrawn into the slot 5.

D'une manière intéressante, la bande 18 est incurvée suivant sa direction transversale, de sorte que la partie déroulée de la bande 18, qui s'étend en regard de la fente 5, devient sensiblement rigide. Ceci est le même principe qui est appliqué par un mètre rétractable comprenant une lame d'acier graduée.Interestingly, the strip 18 is curved in its transverse direction, so that the unwound portion of the strip 18, which extends opposite the slot 5, becomes substantially rigid. This is the same principle that is applied by a retractable meter comprising a graduated steel blade.

Ainsi, ladite bande 18 est, de préférence, formée par une lame d'acier.Thus, said strip 18 is preferably formed by a steel strip.

L'invention n'est bien entendu pas limitée aux formes de réalisation décrites ci-dessus et représentées 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 embodiments described above and shown in the accompanying figures, but many other variants could be envisaged without departing from the scope of the invention.

L'invention peut également être appliquée dans une machine avec une surface de support sensiblement horizontale ou inclinée par rapport à l'horizontale.The invention can also be applied in a machine with a support surface substantially horizontal or inclined relative to the horizontal.

Toutefois dans les formes de réalisation de l'invention décrites ci-dessus une lame de coupe circulaire est utilisée. Il est clair qu'il est possible d'appliquer d'autres types de lames, comme par exemple une lame oblongue qui subit un mouvement de va-et-vient suivant sa direction longitudinale pendant qu'il se déplace à travers la fente.However in the embodiments of the invention described above a circular cutting blade is used. It is clear that it is possible to apply other types of blades, such as an oblong blade which is reciprocated in its longitudinal direction as it moves through the slot.
