Description

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

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

Dans les dispositifs traditionnels de tranchage automatique de pains, la puissance du moteur animant l'élément d'entraînement du pain est constante et par conséquent ne peut être adaptée au type de pain dont le tranchage est souhaité, en fonction de la vitesse de déplacement de l'élément d'entraînement du pain pendant l'opération de découpe. Ceci pose un problème quant à la qualité de la découpe du pain. En effet, dans le cas d'un pain à croûte souple et mie molle, une puissance trop élevée fournie par le moteur et donc une vitesse trop importante de l'élément d'entraînement du pain engendreront une pression trop forte sur le pain lors du début de sa découpe et dès lors un écrasement de ce dernier sur les lames ainsi qu'un déchirement de la mie en cours de découpe. La qualité de la découpe du pain sera dès lors pauvre puisque les tranches présenteront un aspect écrasé du côté de leur bord d'attaque par les lames ainsi que des déchirures de leur mie. Il en va de même avec un pain présentant une croûte dure et une mie molle car dans ce cas, une puissance trop élevée du moteur et donc une vitesse trop importante de l'élément d'entraînement du pain lors du début de la découpe entraîneront également un excès de pression sur la croûte lors de son attaque par les lames et par conséquent une brisure de la croûte contre les lames et un émiettement consécutif de cette dernière, suivi d'un déchirement de la mie comme exposé ci-dessus en cours de découpe. A l'opposé, dans le cas d'un pain à croûte et mie fermes, une puissance trop faible de moteur et donc une vitesse trop lente du dispositif de pousse du pain pourra avoir pour conséquence un défaut de pression sur le pain en cours de découpe et dès lors un frottement des lames de la machine trop prolongé sur la mie du pain qui entraînera un émiettement et un boulochage de cette dernière par les lames. Ceci sera également le cas lorsqu'un pain à croûte dure et mie ferme est découpé puisque la découpe de la croûte en début de découpe sera elle correcte mais celle de la mie par la suite sera également trop lente et pourra donc entraîner l'apparition des émiettement et boulochage susmentionnées.In traditional automatic bread slicing devices, the power of the motor animating the bread-driving element is constant and therefore can not be adapted to the type of bread slicing is desired, depending on the speed of movement of the bread. the bread drive element during the operation of cutting. This poses a problem as to the quality of the bread cut. Indeed, in the case of a bread with soft crust and soft crust, too high power provided by the motor and therefore too high speed of the drive element of the bread will cause too much pressure on the bread during the beginning of its cutting and therefore a crushing of the latter on the blades and a tear of the crumb being cut. The quality of the bread cut will therefore be poor since the slices will have a crushed appearance on the side of their leading edge by the blades as well as tears of their crumb. The same applies to a bread having a hard crust and a soft crumb because in this case, too high power of the motor and therefore a too high speed of the bread driving element at the beginning of cutting will also cause an excess of pressure on the crust during its attack by the blades and consequently a break of the crust against the blades and a subsequent crumbling of the latter, followed by a tearing of the crumb as explained above during cutting . In contrast, in the case of a crust bread and firm slices, too low engine power and therefore too slow speed of the breadmaker device may result in a pressure defect on the bread in progress. cutting and therefore a friction of the blades of the machine too long on the crumb of bread which will cause crumbling and pilling of the latter by the blades. This will also be the case when a hard and firm crust bread is cut, since the cutting of the crust at the beginning of cutting will be correct but that of the crumb later will also be too slow and may therefore lead to the appearance of crumbling and pilling above.

On a tenté de résoudre ce problème d'inadaptation de la puissance du moteur animant l'élément d'entraînement du pain à la nature de celui-ci en munissant l'élément d'entraînement d'un système de contrôle de la puissance de son moteur et donc de la vitesse de l'élément d'entraînement du pain et consécutivement de la pression qu'il exerce sur le pain en cours de découpe. Un tel système peut consister en un levier permettant à l'utilisateur du dispositif de commander manuellement l'élément d'entraînement du pain dans la machine ou en une commande électrique permettent d'augmenter ou de réduire la puissance du moteur animant l'élément d'entraînement durant la découpe dudit pain.Attempts have been made to solve this problem of maladaptation of the power of the motor animating the bread-driving element to the nature of the latter by providing the driving element with a sound power control system. motor and therefore the speed of the drive element of the bread and consecutively the pressure it exerts on the bread being cut. Such a system may consist of a lever allowing the user of the device to manually control the drive element of the bread in the machine or an electrical control can increase or reduce the power of the motor animating the element d during cutting of said bread.

Néanmoins, ces systèmes posent un autre problème puisqu'ils demandent toujours une intervention de l'utilisateur pour les commander et par conséquent d'une part une certaine expérience de celui-ci en matière de types de pains et de conditions de découpe optimales associées à chacun de ces types et d'autre part une mobilisation de l'utilisateur pendant tout le temps de découpe du pain pour commander le système de contrôle de l'élément d'entraînement de ce pain dans le dispositif.However, these systems pose another problem since they always require user intervention to control them and therefore on the one hand a certain experience of it in terms of bread types and optimal cutting conditions associated with each of these types and secondly a mobilization of the user during the entire bread cutting time to control the control system of the drive element of this bread in the device.

On a également tenté de résoudre ce problème en proposant selon les enseignements du brevet US 3 875 840 , un système de contrôle de la puissance d'un premier moteur actionnant l'élément d'entraînement du pain, comprenant un second moteur comprenant au moins un ressort ou un contrepoids pouvant coulisser sur un guide inclinable, de sorte à s'opposer à l'action du premier en fonction de la force exercée par l'élément d'entraînement du pain sur les lames de découpe de ce dernier et donc de la vitesse et/ou de l'accélération dudit élément d'entraînement. Un tel système est cependant mécaniquement complexe dans sa conception et peu fiable et précis dans son fonctionnement.We have also tried to solve this problem by proposing according to the teachings of the patent US 3,875,840 , a system for controlling the power of a first motor actuating the bread-driving element, comprising a second motor comprising at least one spring or a counterweight which can slide on a tilting guide, so as to oppose the action of the first as a function of the force exerted by the drive member of the bread on the cutting blades of the latter and thus the speed and / or acceleration of said drive member. Such a system is however mechanically complex in its design and unreliable and accurate in its operation.

La présente invention résout les problème susmentionnés et pallie les inconvénients qui y sont associés en proposant un dispositif de découpe automatisée de pains en tranches dans lequel la vitesse de l'élément d'entraînement du pain est adaptée de manière automatique au type de pain à découper et en particulier à la dureté de sa croûte et la fermeté de sa mie, et ce tout au long de l'opération de découpe.The present invention solves the aforementioned problems and overcomes the disadvantages associated therewith by providing an automated sliced bread slicing device in which the speed of the bread slicing element is automatically adapted to the type of bread to be sliced. and in particular the hardness of its crust and the firmness of its crumb, and this throughout the cutting operation.

Dès lors, l'invention consiste en un dispositif de découpe automatisée d'un pain en tranches comprenant un élément d'entraînement du pain agencé pour être déplacé au moyen d'un moyen de déplacement couplé audit élément entre une première position de recul dans laquelle le pain à découper peut être chargé dans le dispositif et une seconde position d'avancement dans laquelle le pain découpé peut être retiré du dispositif, celui-ci comprenant en outre un ensemble de lames de découpe du pain disposées sensiblement parallèlement les unes aux autres et agencées pour être animées d'un mouvement alternatif de va-et-vient, l'élément d'entraînement du pain étant agencé pour, lorsque le dispositif est en fonctionnement, entraîner le pain dans un mouvement de translation vers et au travers de l'ensemble de lames entre la première et la seconde position dudit élément, le dispositif comprenant encore un moyen de régulation agencé pour réguler automatiquement la puissance fournie par le moyen de déplacement en fonction de la vitesse et/ou de l'accélération du mouvement de translation de l'élément d'entraînement du pain pendant l'opération de découpe de celui-ci, en comparant la vitesse de déplacement de l'élément d'entraînement à une vitesse prédéterminée et respectivement augmentant ou diminuant la puissance du moyen de déplacement dudit élément d'entraînement lorsque ladite vitesse de déplacement est respectivement inférieure ou supérieure à la vitesse prédéterminée.Therefore, the invention consists of a device for automatically cutting a sliced bread comprising a bread driving element arranged to be moved by means of a displacement means coupled to said element between a first recoil position in which the chopping bread may be loaded into the device and a second feed position in which the chopped bread may be removed from the device, the latter further comprising a set of bread slicing blades arranged substantially parallel to one another and arranged to be reciprocated reciprocally, the bread driving member being arranged to, when the device is in operation, driving the bread in a translation movement to and through the set of blades between the first and second positions of said element, the device further comprising regulating means arranged to regulate automatically the power supplied by the displacement means as a function of the speed and / or the acceleration of the translational movement of the bread-driving element during the cutting operation thereof, by comparing the speed of displacement of the driving element at a predetermined speed and respectively increasing or decreasing the power of the moving means of said driving element when said moving speed is respectively lower or higher than the predetermined speed.

Grâce au moyen de régulation automatique de puissance du moteur en fonction de la vitesse et/ou de l'accélération de l'élément d'entraînement du pain du dispositif selon l'invention par comparaison de la vitesse de déplacement de l'élément d'entraînement à une vitesse prédéterminée et ajustage de la puissance du moyen de déplacement en fonction de la différence entre la vitesse de déplacement en question et la vitesse prédéterminée, la découpe d'un pain est toujours optimisée selon le type de pain en question. En effet, lorsque le pain oppose une résistance importante aux lames en début de découpe, c'est à dire lorsque la croûte du pain est dure, la vitesse de déplacement de l'élément d'entraînement sera rapidement et fortement réduite et cette décélération forte et rapide sera repérée par le moyen de régulation qui diminuera la puissance fournie par le moyen de déplacement de l'élément d'entraînement et la croûte sera dès lors découpée sans qu'elle ne soit brisée par écrasement du pain sur les lames en raison d'une trop grande vitesse et/ou accélération de déplacement de l'élément d'entraînement du pain. Une fois l'épaisseur de la croûte franchie par les lames et la découpe de la mie entamée, la résistance du pain aux lames diminue et la vitesse de déplacement de l'élément d'entraînement du pain augmente. Si cette vitesse ne dépasse pas une valeur seuil prédéterminée, la puissance fournie par le moyen de déplacement de l'élément d'entraînement est augmentée par paliers jusqu'à ce que ladite valeur seuil soit atteinte. Ainsi, quelle que soit la consistance molle ou ferme du pain, la vitesse et/ou l'accélération de déplacement de l'élément d'entraînement dudit pain sont contrôlées pour éviter un déchirement de la mie en raison d'une vitesse ou une accélération excessive ou au contraire l'apparition d'un boulochage de cette mie de par un déplacement trop lent de l'élément d'entraînement du pain et au frottement consécutif excessif des lames sur la mie. Dès lors, plus aucun phénomène d'écrasement de croûte ni de déchirure de mie n'est observé grâce au dispositif selon l'invention.By the means of automatic regulation of the motor power as a function of the speed and / or the acceleration of the bread-driving element of the device according to the invention by comparing the speed of movement of the element of driving at a predetermined speed and adjusting the power of the moving means according to the difference between the speed of displacement in question and the predetermined speed, the cutting of a bread is always optimized according to the type of bread in question. Indeed, when the bread opposes a high resistance to the blades at the beginning of cutting, that is to say when the crust of the bread is hard, the speed of movement of the drive element will be quickly and greatly reduced and this strong and rapid deceleration will be identified by the means of regulation which will reduce the power provided by the means of displacement of the drive element and the crust will therefore be cut without it being broken by crushing the bread on the blades because of too high speed and / or acceleration of movement of the bread drive element. Once the thickness of the crust crossed by the blades and the cutting of the crumbs started, the resistance of the bread to the blades decreases and the speed of movement of the bread-driving element increases. If this speed does not exceed a predetermined threshold value, the power supplied by the moving means of the driving element is increased stepwise until said threshold value is reached. Thus, regardless of the soft or firm consistency of the bread, the speed and / or the acceleration of movement of the driving element of said bread are controlled to prevent tearing of the crumb due to a speed or an acceleration excessive or on the contrary the occurrence of a pilling of this crumbs by a too slow movement of the drive element of the bread and the excessive consecutive friction of the blades on the crumb. Therefore, no crust crusting or tear creasing phenomenon is observed thanks to the device according to the invention.

L'invention va à présent être décrite plus en détails au moyen d'un exemple illustrant un mode de réalisation non limitatif de sa portée et en référence à la figure 1 jointe représentant une vue schématique en coupe transversale d'un dispositif selon l'invention.The invention will now be described in greater detail by means of an example illustrating a non-limiting embodiment of its scope and with reference to the attached FIG. 1 representing a schematic cross-sectional view of a device according to the invention. .

Le dispositif 1 selon l'invention comporte un châssis 2 comprenant une table de découpe 3 d'un pain 4 que l'on dispose dans un compartiment de chargement 5 du dispositif. Celui-ci comprend encore un élément d'entraînement 7 du pain 4 et un ensemble de lames 8 disposées sensiblement parallèlement les unes aux autres et agencées pour être animées d'un mouvement alternatif de va-et-vient pour découper le pain 4 en tranches. Un presse pain 6 est également prévu, constitué d'une lame exerçant une pression sur le dessus du pain pour éviter son tressaillement pendant l'opération de découpe Du côté de l'ensemble de lames 8 opposé au compartiment de chargement 5 du pain 4 est prévu un compartiment 9 de déchargement du pain 4 coupé en tranches. L'élément d'entraînement 7 du pain 4 est agencé pour être déplacé selon un mouvement de translation parallèlement à la table de découpe 3 et transversalement à l'ensemble de lames 8 entre une première position de recul dans laquelle un pain 4 peut être introduit dans le compartiment de chargement 5 et une seconde position d'avancement dans laquelle l'élément d'entraînement 7 du pain est adjacent à l'ensemble de lames 8 et le pain 4 coupé en tranches et disposé dans le compartiment 9 de déchargement peut être retiré du dispositif 1. Le déplacement de l'élément d'entraînement 7 est effectué au moyen d'un moteur électrique 10 comprenant un rotor et un stator, couplé audit élément d'entraînement 7 par un vérin 11 actionnant un bras articulé 12 comprenant un premier élément 12a articulé par une charnière ou une rotule à un second élément 12b, une première extrémité du bras 12 pouvant pivoter autour d'un pivot 13 et une seconde extrémité dudit bras 12 étant connectée à l'élément d'entraînement 7. Alternativement au moteur électrique 10, un autre moyen de déplacement de l'élément d'entraînement 7 peut être prévu, par exemple une source ou un réservoir d'air comprimé actionnant par exemple un vérin pneumatique.The device 1 according to the invention comprises a frame 2 comprising a cutting table 3 of a bread 4 that is arranged in a loading compartment 5 of the device. This still includes a drive element 7 of the bread 4 and a set of blades 8 arranged substantially parallel to each other and arranged to be reciprocated reciprocating to cut the bread 4 slices. A bread press 6 is also provided, consisting of a blade exerting a pressure on the top of the bread to avoid its thrill during the cutting operation. The side of the blade assembly 8 opposite the loading compartment 5 of the bread 4 is provided a compartment 9 unloading bread 4 cut into slices. The driving element 7 of the bread 4 is arranged to be moved in a translation movement parallel to the cutting table 3 and transversely to the blade assembly 8 between a first recoil position in which a roll 4 can be introduced. in the loading compartment 5 and a second feed position in which the driving element 7 of the bread is adjacent to the blade assembly 8 and the sliced bread 4 and disposed in the unloading compartment 9 can be removed from the device 1. The displacement of the driving element 7 is effected by means of an electric motor 10 comprising a rotor and a stator, coupled to said driving element 7 by a jack 11 actuating an articulated arm 12 comprising a first element 12a articulated by a hinge or a ball joint to a second element 12b, a first end of the arm 12 being able to pivot about a pivot 13 and a second end of said arm as 12 being connected to the driving element 7. Alternatively to the electric motor 10, another means of displacement of the driving element 7 can be provided, for example a source or a compressed air reservoir actuating for example a pneumatic cylinder.

La puissance fournie par le moteur 10 couplé à l'élément d'entraînement 7 du pain 4 pendant le fonctionnement du dispositif 1 est régulée automatiquement par un moyen de régulation 14 en fonction de la vitesse dudit élément d'entraînement 7, laquelle est conditionnée par la résistance que le pain 4 et le presse pain 6 opposent à l'ensemble de lames 8 pendant l'opération de découpe dudit pain. En effet, le presse pain 6 en exerçant une pression sur ledit pain 4 augmente la résistance que celui-ci oppose par lui-même à l'ensemble de lames 8. Le moyen de régulation 14 est agencé pour mesurer la vitesse de rotation du rotor dans le stator du moteur 10 pour déterminer la vitesse du mouvement de translation de l'élément d'entraînement 7 du pain 4 et est également agencé pour comparer la vitesse mesurée à une vitesse prédéterminée et pour augmenter ou diminuer la puissance du moteur 10 lorsque cette vitesse mesurée est respectivement inférieure ou supérieure à la vitesse prédéterminée.The power supplied by the motor 10 coupled to the driving element 7 of the bread 4 during the operation of the device 1 is regulated automatically by a regulating means 14 as a function of the speed of said driving element 7, which is conditioned by the resistance that the bread 4 and the bread press 6 oppose to the whole blades 8 during the cutting operation of said bread. Indeed, the press roll 6 by exerting pressure on said roll 4 increases the resistance that it opposes by itself to the set of blades 8. The control means 14 is arranged to measure the speed of rotation of the rotor in the stator of the motor 10 to determine the speed of the translational movement of the driving element 7 of the bread 4 and is also arranged to compare the speed measured at a predetermined speed and to increase or decrease the power of the motor 10 when this measured speed is respectively lower or higher than the predetermined speed.

Si un autre moyen de déplacement de l'élément d'entraînement 7 est utilisé, tel qu'une source ou un réservoir d'air comprimé, c'est la vitesse de déplacement de l'élément d'entraînement 7 elle-même qui pourra être directement mesurée par le moyen de régulation 14, par exemple grâce à des capteurs de position tels que des cellules photoélectriques disposées sur le parcours de l'élément d'entraînement 7.If another means of moving the driving element 7 is used, such as a source or a reservoir of compressed air, it is the speed of movement of the driving element 7 itself that can be directly measured by the control means 14, for example by means of position sensors such as photocells arranged on the path of the driving element 7.

Ainsi, quel que soit le type de pain découpé, la vitesse de cette découpe est en permanence optimisée par le dispositif selon l'invention. Lorsqu'un pain à croûte dure ou au contraire très souple est mis à découper dans le dispositif selon l'invention et que la croûte atteint l'ensemble de lames 8, une résistance très importante au mouvement de translation de l'élément d'entraînement 7 du pain est opposée par la croûte à la découpe par l'ensemble de lames 8, soit en raison de la dureté de ladite croûte ou de la compression du pain à croûte souple. Même dans le cas d'un pain d'un autre type, une telle résistance peut être provoquée, principalement alors par la pression exercée par le presse pain sur ledit pain. Cette résistance entraîne un pic d'intensité du courant consommé par le moteur 10 qui indique que la puissance de ce moteur et donc le courant consommé doivent être réduits pour éviter que la croûte du pain ne soit écrasée contre les lames en raison d'une pression trop forte exercée par l'élément d'entraînement 7 sur le pain. Ce pic d'intensité correspond à une valeur prédéterminée et peut être mesuré et le courant ainsi donc que la puissance du moteur 10 peuvent en réaction être fortement réduits jusqu'à une autre valeur prédéterminée pour que la découpe de la croûte du pain soit effectuée de manière optimale sans écrasement. C'est pourquoi, le moyen de régulation 14 du dispositif 1 selon l'invention est également agencé pour diminuer l'intensité du courant consommé par le moteur 10 jusqu'à une première valeur prédéterminée lorsque cette intensité dépasse une seconde valeur prédéterminée.Thus, regardless of the type of bread cut, the speed of this cut is permanently optimized by the device according to the invention. When a bread crust hard or otherwise very flexible is cut into the device according to the invention and the crust reaches the blade assembly 8, a very significant resistance to the translational movement of the drive element 7 bread is opposed by the crust to the cut by the set of blades 8, either because of the hardness of said crust or the compression of soft crust bread. Even in the case of a bread of another type, such resistance can be caused, mainly then by the pressure exerted by the bread press on said bread. This resistance causes a peak intensity of the current consumed by the engine 10 which indicates that the power of the engine and therefore the current consumed must be reduced to prevent the crust of the bread is crushed against the blades because of a excessive pressure exerted by the drive member 7 on the bread. This peak intensity corresponds to a predetermined value and can be measured and the current and thus the power of the motor 10 can in return be strongly reduced to another predetermined value so that the crust of the bread is cut from optimally without crushing. Therefore, the regulating means 14 of the device 1 according to the invention is also arranged to reduce the intensity of the current consumed by the motor 10 to a first predetermined value when this intensity exceeds a second predetermined value.

Dans le cas où un autre moyen de déplacement que le moteur 10 est utilisé, tel qu'une source ou un réservoir d'air comprimé, le pic d'intensité susmentionné est remplacé par un pic de pression de l'air utilisé pour déplacer l'élément d'entraînement 7. La puissance régulée est également dans ce cas la pression de l'air en question.In the case where another moving means that the motor 10 is used, such as a source or a tank of compressed air, the above-mentioned intensity peak is replaced by a peak pressure of the air used to move the air. In this case, the controlled power is also the air pressure in question.

Une fois la découpe de la croûte du pain effectuée, l'ensemble de lames 8 attaque la découpe de la mie du pain 4. Si la vitesse de déplacement de l'élément d'entraînement 7 et donc de découpe du pain 4 est alors inférieure à une valeur prédéterminée, le moyen de régulation 14 augmentera la puissance du moteur 10 jusqu'à ce que cette valeur soit atteinte, de sorte à éviter qu'une vitesse trop lente ne conduise à un frottement excessif de l'ensemble de lames 8 sur la mie du pain 4 et à l'apparition consécutive d'un boulochage de cette mie. Si d'aventure, dans le cas par exemple d'un pain à mie très légère, la valeur prédéterminée de la vitesse de découpe du pain était dépassée, le moyen de régulation 14 commanderait une diminution de la puissance du moteur 10 pour éviter tout déchirement de la mie dû à une vitesse ou à une accélération de déplacement de l'élément d'entraînement 7 excessive. Le moyen de régulation 14 est de plus agencé pour provoquer une inversion du sens de déplacement de l'élément d'entraînement 7 du pain 4 lorsqu'il atteint sa première ou sa seconde position. Cette inversion peut être provoquée de plusieurs manières Elle peut être commandée par au moins une cellule photoélectrique (non illustrée) agencée pour repérer l'arrivée de l'élément d'entraînement 7 dans sa première ou sa seconde position ou alternativement en prévoyant que le moyen de régulation 14 soit agencé pour mesurer le nombre de tours effectués par le rotor du moteur 10 dans son stator et pour provoquer ladite inversion depuis l'une des première ou seconde positions de l'élément d'entraînement 7 lorsque ledit nombre de tours atteint une valeur prédéterminée depuis l'autre des première ou seconde positions de l'élément d'entraînement 7. Alternativement encore, ou concomitamment, l'inversion en question peut être provoquée depuis l'une des première ou seconde positions de l'élément d'entraînement 7 lorsque l'intensité du courant consommé par le moteur 10 dépasse une valeur seuil prédéterminée apparaissant lors de la butée de l'élément d'entraînement 7 contre un arrêt disposé au niveau de sa première et/ou seconde positions.Once the cutting of the crust of the bread has been performed, the set of blades 8 attacks the cutting of the crumb of the bread 4. If the speed of displacement of the driving element 7 and therefore cutting of the bread 4 is then lower at a predetermined value, the regulating means 14 will increase the power of the motor 10 until this value is reached, so as to prevent a too slow speed from leading to excessive friction of the blade assembly 8 on the crumb of bread 4 and the subsequent appearance of a pilling of this crumb. If by chance, in the case for example of a very light bread roll, the predetermined value of the cutting speed of the bread was exceeded, the control means 14 would control a decrease in the power of the motor 10 to avoid any tearing due to a speed or acceleration of displacement of the excessive drive member 7. The regulating means 14 is furthermore arranged to cause a reversal of the direction of movement of the driving element 7 of the bread 4 when it reaches its first or its second position. This inversion can be caused in several ways It can be controlled by at least one photoelectric cell (not shown) arranged to locate the arrival of the drive element 7 in its first or second position or alternatively by providing that the means 14 is arranged to measure the number of revolutions made by the rotor of the motor 10 in its stator and to cause said inversion from one of the first or second positions of the driving element 7 when said number of revolutions reaches a predetermined value from the other of the first or second positions of the driving element 7. Alternatively again, or concomitantly, the inversion in question can be caused from one of the first or second positions of the driving element. 7 when the intensity of the current consumed by the motor 10 exceeds a predetermined threshold value occurring during the abutment of the element 7 against a stop disposed at its first and / or second positions.

En pratique, le moyen de régulation 14 pourra comprendre un circuit de contrôle de la puissance fournie par le moteur 10 commandé par une puce électronique programmée pour, à partir d'une mesure par un ampèremètre de l'intensité du courant consommé par le moteur 10 et du nombre de tours par unité de temps du rotor dudit moteur 10 dans son stator, indiqué par exemple au moyen d'un disque de comptage couplé audit rotor, calculer la vitesse et/ou l'accélération de l'élément d'entraînement 7 et commander le circuit de contrôle de puissance susmentionné. Le moyen de régulation 14 est relié au moteur 10 par un premier câble électrique 15 transmettant les informations d'intensité de courant et de vitesse de moteur mentionnées ci-dessus et un second câble électrique 16 alimentant le moteur 10 en électricité.In practice, the regulating means 14 may comprise a circuit for controlling the power supplied by the motor 10 controlled by an electronic chip programmed to, from a measurement by an ammeter of the intensity of the current consumed by the motor 10 and the number of revolutions per unit time of the rotor of said motor 10 in its stator, indicated for example by means of a counting disc coupled to said rotor, calculating the speed and / or the acceleration of the driving element 7 and control the aforementioned power control circuit. The regulating means 14 is connected to the motor 10 by a first electric cable 15 transmitting the current and motor speed information mentioned above and a second electric cable 16 supplying the motor 10 with electricity.
