Description

La présente invention se rapporte à une machine à couper le pain en tranches, en particulier à une machine semi-automatique. Une telle machine comprend un dispositif de coupe généralement à couteaux multiples parallèles à mouvement alternatif et un dispositif pousse-pain, montés sur un châssis. Le dispositif pousse-pain est agencé pour pouvoir se déplacer entre une position de recul dans laquelle le pain peut être disposé entre le dispositif pousse-pain et le dispositif de coupe et une position d'avancement dans laquelle le dispositif pousse-pain est adjacent au dispositif de coupe. Le pain à couper est donc guidé et poussé par le dispositif pousse-pain vers le dispositif de coupe, lesdits dispositifs étant actionnés électriquement et s'arrêtant après chaque cycle de coupe, une fois le dispositif pousse-pain revenu en position de recul. Un bouton de démarrage commande le mouvement du dispositif de coupe et du dispositif coupe-pain.The present invention relates to a cutting machine sliced bread, especially to a semi-automatic machine. A such machine comprises a cutting device generally knives multiple parallel reciprocating and a pusher device, mounted on a chassis. The pusher device is arranged to able to move between a recoil position in which bread can be arranged between the pusher device and the cutting device and a forward position in which the device is a breadfruit adjacent to the cutting device. The bread to be cut is therefore guided and pushed by the pusher device to the cutting device, said devices being electrically powered and stopping after each cutting cycle, once the device toddler income in position of decline. A start button controls the movement of the device cutter and bread cutter device.

Ce type de machine est utilisé dans les boulangeries de détail et dans les grandes surfaces, en libre-service, par le consommateur lui-même. Pour des raisons de sécurité et d'hygiène, une norme européenne WI 153028 prescrit que les machines à couper le pain semi-automatiques doivent être munies d'un capot isolant l'utilisateur du dispositif de coupe et du dispositif coupe-pain durant leur fonctionnement au cours d'un cycle de coupe d'un pain. La fermeture du capot en question peut actionner le démarrage de la machine. Un bouton additionnel doit également être prévu, accessible à l'utilisateur, pour lui permettre d'arrêter la machine durant son fonctionnement. This type of machine is used in bakeries retail and supermarkets, in self-service, by the consumer himself. For reasons of safety and hygiene, a European standard WI 153028 prescribes that machines to cut the semi-automatic breads must be equipped with an insulating cover the user of the cutting device and the bread-cutter device during their functioning during a cutting cycle of a loaf. The closure of hood in question can operate the machine start. A button additional must also be provided, accessible to the user, for him allow the machine to stop during operation.

La demande de brevet EP 1 086 789 A1 décrit une machine à couper le pain semi-automatique qui comprend un capot pouvant se déplacer entre une position de fermeture dans laquelle il rend inaccessible à un utilisateur de la machine le dispositif de coupe et une position d'ouverture dans laquelle il rend accessible audit utilisateur le dispositif pousse-pain, le dispositif pousse-pain étant muni d'un premier moyen et le capot d'un second moyen agencés pour coopérer lors du déplacement du dispositif pousse-pain vers sa position de recul pour déplacer le capot vers sa position d'ouverture.The patent application EP 1 086 789 A1 describes a machine for cut the semi-automatic bread that includes a hood that can move between a closed position in which it renders inaccessible to a user of the machine the cutting device and a opening position in which it makes accessible to said user the pusher device, the pusher device being provided with a first medium and the cover of a second means arranged to cooperate during the moving the pusher device to its recoil position for move the hood to its open position.

Le second moyen comprend un dispositif de mise en mouvement du capot exerçant sur celui-ci une force élastique et constitué en particulier d'un piston à gaz fixé à un point d'articulation solidaire du châssis de la machine et à une partie de fixation fixée au capot. Ce second moyen comprend en outre une roulette fixée au capot par l'intermédiaire d'un support monté sur le capot de manière telle à pouvoir se déplacer autour d'un pivot et revenir à sa position de départ grâce à un ressort de rappel.The second means comprises a device for setting in motion of the cover exerting on it an elastic force and constituted in particular of a gas piston fixed to a joint point of articulation of the frame of the machine and a fastening part attached to the hood. This second means further comprises a caster attached to the hood by via a support mounted on the hood so as to be able to move around a pivot and return to its starting position through a return spring.

Le premier moyen comprend un rebord fixé au dispositif pousse-pain.The first means comprises a rim attached to the bread pusher device.

Lorsque le capot est fermé durant un cycle de coupe et que le dispositif pousse-pain se déplace vers sa position de recul une fois coupé le pain introduit dans la machine, le rebord fixé au dispositif pousse-pain entre en contact avec la roulette susmentionnée et vient appuyer sur celle-ci de sorte à provoquer un déplacement du capot de sa position de fermeture vers sa position d'ouverture autour d'un pivot fixé au châssis de la machine. Ce pivotement est suffisant pour que le point d'articulation du piston dépasse le point d'équilibre de ce dernier. La rotation du capot se poursuit alors jusqu'à ce qu'il atteigne sa position d'ouverture. Grâce à la force élastique exercée par le piston sur le capot dans sa position d'ouverture, celui-ci s'y maintient de manière stable. When the hood is closed during a cutting cycle and the pusher device moves to its recoil position once cut the bread introduced into the machine, the rim fixed to the device pusher comes in contact with the aforementioned roulette and comes press on it so as to cause a movement of the cover of its closing position to its open position around a fixed pivot to the frame of the machine. This pivoting is sufficient for the point piston articulation exceeds the equilibrium point of the latter. The hood rotation then continues until it reaches its position opening. Thanks to the elastic force exerted by the piston on the hood in its open position, it is stably maintained.

Lorsque l'utilisateur referme le capot une fois un pain introduit dans la machine et disposé entre le dispositif pousse-pain en position de recul et le dispositif de coupe, la roulette dont question plus haut vient reposer sur le dispositif pousse pain grâce au pivotement du support de ladite roulette. La fermeture du capot par l'utilisateur enclenche le démarrage de la machine et un nouveau cycle de coupe commence.When the user closes the hood once a loaf introduces in the machine and arranged between the device recoil and cutting device, the roulette of which question above comes rest on the device pushes bread through the pivoting of the support of said roulette. Closing the hood by the user engages the starting the machine and a new cutting cycle begins.

La machine décrite par la demande de brevet EP 1 086 789 A1 présente l'inconvénient de comprendre des moyens d'ouverture du capot complexes, donc difficiles et onéreux à réaliser. En particulier, le second moyen mentionné doit comprendre un piston à gaz ou un dispositif équivalent ainsi qu'une roulette montée sur un support lui-même monté sur un pivot et muni d'un ressort de rappel.The machine described by the patent application EP 1 086 789 A1 has the disadvantage of including means of opening the hood complex, so difficult and expensive to achieve. In particular, the second mentioned means shall include a gas piston or device equivalent and a wheel mounted on a support itself mounted on a pivot and provided with a return spring.

Le but de la présente invention est d'offrir une machine à couper le pain comprenant des moyens d'ouverture de son capot qui soient à la fois efficaces et plus simples que ceux prévus par l'état de la technique.The object of the present invention is to provide a cutting machine the bread comprising means for opening its hood which are at the effective and simpler than those provided by the state of the art.

Dès lors, une machine à couper le pain selon l'invention est caractérisée en ce que le premier moyen d'ouverture du capot dont est muni le dispositif pousse-pain peut exercer une force élastique sur le second moyen de sorte à permettre le déplacement du capot de sa position de fermeture à sa position d'ouverture et d'assurer la stabilité de cette position d'ouverture du capot.Therefore, a bread-cutting machine according to the invention is characterized in that the first hood opening means of which is equipped with the push-pull device can exert an elastic force on the second means so as to allow the movement of the hood of its closing position to its open position and to ensure the stability of this opening position of the hood.

De la sorte, lorsque le capot de la machine selon l'invention est en position de fermeture et que le dispositif pousse-pain se déplace vers sa position de recul, le premier moyen dont ce dispositif est muni vient contacter le second moyen dont est muni le capot et exerce une force élastique sur ce dernier de sorte à provoquer son déplacement vers sa position d'ouverture. La force élastique en question continuant à s'exercer sur le second moyen en position d'ouverture du capot par le premier moyen en position de recul du dispositif pousse-pain, la stabilité de cette position est assurée simplement de la sorte, sans que le second moyen doive présenter la complexité de celui selon l'état de la technique cité plus haut.In this way, when the hood of the machine according to the invention is in closing position and that the device pushes to move towards its recoil position, the first means of which this device is provided comes contact the second means of which the hood is equipped and exerts a force elastic on the latter so as to cause its movement towards its opening position. The elastic force in question continues to operate on the second means in the hood opening position by the first means in the retracted position of the pusher device, the stability this position is ensured simply in this way, without the second the medium must present the complexity of the one according to the state of the art cited above.

Des modes de réalisation préférés de l'invention sont exposés dans les revendications.Preferred embodiments of the invention are exposed in the claims.

L'invention sera exposée plus en détails par la description qui suit, donnée à titre d'illustration et accompagnée des dessins annexés dans lesquels,The invention will be explained in more detail by the description which follows, given as an illustration and accompanied by the accompanying drawings in which,

Les figures 1 et 2 représentent une vue shématique en coupe d'une forme de réalisation préférée de l'invention représentée respectivement en position d'ouverture et de fermeture du capot;Figures 1 and 2 show a schematic sectional view of a preferred embodiment of the invention shown respectively in the open and closed position of the hood;

Les figures 3 à 8 sont des vues à plus grande échelle des moyens d'ouverture du capot de la machine selon l'invention représentée aux figures 1-2 durant le déplacement du dispositif pousse-pain depuis sa position d'avancement vers sa position de recul, le capot étant en position de fermeture lors du commencement de ce déplacement lors du déplacement du capot de sa position d'ouverture vers sa position de fermeture une fois le dispositif pousse pain parvenu en position de recul.Figures 3 to 8 are views on a larger scale of the means opening of the hood of the machine according to the invention shown in figures 1-2 during the displacement of the pusher device since its forward position towards its retracted position, the hood being in closing position at the beginning of this movement during moving the cover from its open position to its position of closing once the device pushes bread arrived in the recoil position.

Les figures 9 à 11 sont des vues à plus grande échelle des moyens d'ouverture du capot de la machine selon l'invention représentée aux figures 1-2 durant le déplacement du dispositif pousse-pain depuis sa position d'avancement vers sa position de recul, le capot étant en position d'ouverture lors du commencement de ce déplacement et du déplacement du capot de sa position d'ouverture vers sa position de fermeture une fois le dispositif pousse pain parvenu en position de recul.Figures 9 to 11 are views on a larger scale of the means opening of the hood of the machine according to the invention shown in figures 1-2 during the displacement of the pusher device since its forward position towards its retracted position, the hood being in opening position at the beginning of this movement and moving the cover from its open position to its position of closing once the device pushes bread arrived in the recoil position.

Sur les figures 1 et 2 qui représentent une machine à couper le pain selon l'invention généralement désignée par la référence 9 on distingue un dispositif pousse-pain 3 monté sur le châssis 2 de la machine, laquelle comprend également un capot 1 monté sur le châssis 2 par l'intermédiaire d'un pivot 5 autour duquel le capot 1 peut se déplacer entre une position d'ouverture dans laquelle il est représenté à la figure 1 et une position de fermeture dans laquelle il est représenté à la figure 2. Le capot 1 est muni d'un second moyen d'ouverture du capot constitué d'une came 4 solidaire du capot et pouvant se déplacer avec lui autour du pivot 5. La came 4 présente une gorge 7 agencée pour recevoir une extrémité d'un premier moyen d'ouverture du capot constitué d'un ressort 6 qui exerce une force élastique sur la came 4 lorsqu'il entre en contact avec cette dernière lors du déplacement du dispositif pousse-pain de sa position d'avancement vers sa position de recul. Les premiers et seconds moyens 4 et 6 coopèrent pour permettre l'ouverture du capot et, une fois dans sa position d'ouverture, son maintien de manière stable dans cette position. Le ressort 6 est monté sur le dispositif pousse-pain 3, par exemple au moyen de bagues de fixations (non représentées), de manière telle à ce que l'axe dudit ressort soit sensiblement perpendiculaire au sens de déplacement du dispositif pousse-pain. Le ressort 6 comprend un membre 10 qui n'est pas fixée au dispositif pousse-pain 6 et est recourbée à son extrémité de manière à pouvoir engager la gorge 7 de la came 4. L'extrémité recourbée du ressort 6 traverse un galet 11 agencé pour entrer en contact avec la came 4 de sorte que le membre 10 du ressort 6 puisse suivre le mouvement de la came 4 avec un faible degré de friction. Une butée 8 montée sur le dispositif pousse-pain 3 sensiblement perpendiculaire au sens de déplacement dudit dispositif pousse-pain est en outre prévue et agencée pour limiter le déplacement du membre 10 du ressort 6.
Le dispositif pousse-pain 3 est monté sur des guides (non représentés) prévus dans le châssis 2 de la machine 9 dans lesquels il peut coulisser entre deux butées (non représentées), l'une fixant la position d'avancement du dispositif pousse-pain 3 et l'autre sa position de recul.
En position de fermeture du capot 2 et lorsque le dispositif pousse-pain est en position de recul (figure 2), le membre 10 du ressort 6 exerce une force élastique sur la came 4. Dans cette position, le capot 2 exerce également de par son poids une force opposée sur le ressort 6 par l'intermédiaire de la came 4, cette force étant suffisante pour compenser la force élastique exercée par le ressort 6 sur la came 4 de sorte que la position de fermeture du capot 2 demeure stable dans cette position.In FIGS. 1 and 2, which show a bread slicing machine according to the invention generally designated by the reference numeral 9, there is a pusher device 3 mounted on the frame 2 of the machine, which also comprises a cover 1 mounted on the frame 2 via a pivot 5 around which the cover 1 can move between an open position in which it is shown in Figure 1 and a closed position in which it is shown in Figure 2. The cover 1 is provided with a second cover opening means consisting of a cam 4 integral with the cover and movable with it around the pivot 5. The cam 4 has a groove 7 arranged to receive an end of a first means for opening the cover consisting of a spring 6 which exerts an elastic force on the cam 4 when it comes into contact with the latter when moving the pusher device from its advancing position to its position of re ass. The first and second means 4 and 6 cooperate to allow the opening of the cover and, once in its open position, its holding stably in this position. The spring 6 is mounted on the pusher device 3, for example by means of fixing rings (not shown), so that the axis of said spring is substantially perpendicular to the direction of movement of the pusher device. The spring 6 comprises a member 10 which is not fixed to the device 6 and is bent at its end so as to engage the groove 7 of the cam 4. The curved end of the spring 6 passes through a roller 11 arranged to contact the cam 4 so that the member 10 of the spring 6 can follow the movement of the cam 4 with a low degree of friction. An abutment 8 mounted on the pusher device 3 substantially perpendicular to the direction of movement of said pusher device is further provided and arranged to limit the displacement of the member 10 of the spring 6.
The pusher device 3 is mounted on guides (not shown) provided in the frame 2 of the machine 9 in which it can slide between two stops (not shown), one fixing the advancing position of the pushing device. bread 3 and the other its recoil position.
In the closed position of the cover 2 and when the pusher device is in the retracted position (FIG. 2), the member 10 of the spring 6 exerts an elastic force on the cam 4. In this position, the cover 2 also exerts its weight an opposite force on the spring 6 via the cam 4, this force being sufficient to compensate for the elastic force exerted by the spring 6 on the cam 4 so that the closed position of the cover 2 remains stable in this position.

Les figures 3 à 4 illustrent schématiquement le mouvement de déplacement de la came 4 sous l'action du ressort 6 lors du déplacement du dispositif pousse-pain depuis sa position d'avancement vers sa position de recul. Le déplacement de la came 4 entraíne celui du capot (non représenté) depuis sa position de fermeture (figure 3) jusqu'à à sa position d'ouverture (figure 5). Comme l'illustre la figure 3, au cours du déplacement du dispositif pousse-pain 4 vers sa position de recul, le ressort 6 entre en contact avec la came 4 au niveau du galet 11 porté par le membre 10 dudit ressort 6. une force élastique est exercée par le ressort 6 sur la came 4, laquelle force provoque le déplacement de la came 4 autour du pivot 5 et par conséquent le déplacement du capot vers sa position d'ouverture (figure 4). lorsque cette position d'ouverture est atteinte, le membre 10 du ressort 6 vient s'engager dans la gorge 7 de la came 4.Figures 3 to 4 schematically illustrate the movement of displacement of the cam 4 under the action of the spring 6 during the displacement of the pusher device from its advancing position to its recoil position. The displacement of the cam 4 causes that of the hood (not shown) from its closed position (FIG. 3) to its open position (Figure 5). As illustrated in Figure 3, during the moving the device 4 to its recoil position, the spring 6 comes into contact with the cam 4 at the roller 11 carried by the member 10 of said spring 6. an elastic force is exerted by the spring 6 on the cam 4, which force causes the displacement of the cam 4 around the pivot 5 and therefore the movement of the hood towards its open position (Figure 4). when this open position is reached, the member 10 of the spring 6 engages in the groove 7 of the cam 4.

Les figures 6 à 8 illustrent schématiquement le mouvement de déplacement de la came 4 et du ressort 6 lors du déplacement du capot par l'utilisateur de la machine de la position d'ouverture dudit capot vers sa position de fermeture, pendant que le dispositif pousse-pain 4 est en position de recul. La came 4 exerce une force sur le membre 10 du ressort 6, force qui compense et dépasse celle exercée par ledit ressort sur ladite came. Dès lors, le membre 10 du ressort 6 est forcé de suivre le contour de la came 4 par l'intermédiaire du galet 11 en contact avec ladite came, jusqu'à la positi2 on de fermeture du capot (figure 8). A ce moment, le démarrage de la machine est enclenché et un cycle de coupe commence.
Les figures 9 à 11 illustrent schématiquement la coopération de la came 4 et du ressort 6 lors du déplacement du dispositif pousse-pain vers sa position de recul, lorsque le capot est ouvert durant ce déplacement et que le membre 10 du ressort 6 entre en contact avec la came 4 (figure 9), lors de l'engagement du membre 10 du ressort 6 dans la gorge 7 de la came 4 lorsque la position de recul du dispositif pousse-pain est atteinte (figure 10) et lors du déplacement du capot par un utilisateur de la machine de la position d'ouverture dudit capot vers sa position de fermeture pendant que le dispositif pousse-pain est en position de recul (figure 11).FIGS. 6 to 8 schematically illustrate the displacement movement of the cam 4 and of the spring 6 during the movement of the hood by the user of the machine from the opening position of said hood to its closed position, while the device is pushing -pain 4 is in recoil position. The cam 4 exerts a force on the member 10 of the spring 6, which force compensates and exceeds that exerted by said spring on said cam. Therefore, the member 10 of the spring 6 is forced to follow the contour of the cam 4 by means of the roller 11 in contact with said cam, to the positi 2 on closing the hood (Figure 8). At this time, the machine starts up and a cutting cycle begins.
Figures 9 to 11 schematically illustrate the cooperation of the cam 4 and the spring 6 during movement of the pusher device to its retracted position, when the cover is open during this movement and the member 10 of the spring 6 comes into contact with the cam 4 (Figure 9), during the engagement of the member 10 of the spring 6 in the groove 7 of the cam 4 when the retracted position of the device is reached (Figure 10) and when moving the hood by a user of the machine from the open position of said cover to its closed position while the device is in the recoil position (Figure 11).

Dans la forme de réalisation de l'invention décrite ci-avant, le capot n'est pas doté d'un verrouillage en position fermée lorsque la machine est en fonctionnement durant un cycle de coupe. Un tel verrouillage peut être obtenu en combinant le mécanisme d'ouverture du capot décrit ci-avant avec un mécanisme de verrouillage tel que décrit dans la demande de brevet EP 1 086 789 A1.In the embodiment of the invention described above, the hood is not not equipped with a lock in the closed position when the machine is in operation during a cutting cycle.
