Description

La présente invention concerne une trancheuse de denrées, en particulier une trancheuse de pain, comprenant un jeu de lames de coupe agencé pour couper la denrée en tranches et une table de sortie disposée en aval du jeu de lames et agencée pour soutenir les tranches dans leur mouvement lorsqu'elles quittent le jeu de lames, laquelle trancheuse comporte un organe d'emballage et un organe de maintien qui est disposé à hauteur de la table de sortie et agencé pour maintenir les tranches adjacentes les unes des autres dans leur mouvement sur la table de sortie.The present invention relates to a food slicer, in particular a bread slicer, comprising a set of cutting blades arranged to cut the food into slices and an output table disposed downstream of the set of blades and arranged to support the slices in their movement when they leave the blade set, which slicer has a packing member and a holding member which is arranged at the height of the output table and arranged to hold the adjacent slices of each other in their movement on the table Release.

Une telle trancheuse est connue et est commercialisée par le demandeur. La trancheuse comporte une table de sortie qui soutient les tranches du pain qui sortent du jeu de lames. Comme la trancheuse est en particulier agencée pour un usage dans un magasin de grande surface, elle est équipée d'un organe de maintien qui maintient les tranches ensemble pour ainsi éviter, d'une part, que les tranches tombent et, d'autre part, que l'utilisateur doive maintenir les tranches ensemble à proximité du jeu de lames. L'organe d'emballage est formé par une planche disposée de façon inclinée sur laquelle l'utilisateur pose les tranches avant d'enfiler un sac sur le pain coupé.Such a slicer is known and is marketed by the applicant. The slicer has an exit table that supports slices of bread that come out of the blade set. As the slicer is in particular designed for use in a supermarket, it is equipped with a holding member that holds the slices together to prevent, on the one hand, the slices fall and secondly , that the user must keep the slices together near the blade set. The packaging member is formed by an inclined board on which the user places the slices before putting a bag on the bread cut.

Un désavantage des trancheuses connues, ainsi que des trancheuses en général, est qu'il faut une certaine dextérité pour ensacher le pain ou autre denrée. En effet, il faut éviter que les tranches tombent et décomposent ainsi le pain lors de la prise et du transport du pain coupé entre la table de sortie et l'organe d'emballage. De plus, il faut poser les tranches correctement alignées sur l'organe d'emballage pour pouvoir l'ensacher convenablement. Enfin, comme il y a différents formats de pain, il faut que l'utilisateur choisisse le sac adéquat et que le magasin ait un stock suffisant de différentes sortes de sacs. Lorsque la trancheuse est placée en grande surface il faut aussi éviter que, dû aux différentes opérations à réaliser, un utilisateur, qui n'aurait pas la dextérité requise, monopolise trop longtemps la trancheuse.A disadvantage of known slicers, as well as slicers in general, is that it takes some dexterity to bag bread or other food. Indeed, it is necessary to prevent the slices fall and break down the bread when taking and transporting bread cut between the output table and the packaging member. In addition, it is necessary to place the slices properly aligned on the packaging member to be able to ensacher properly. Finally, as there are different sizes of bread, it is necessary that the user chooses the appropriate bag and that the store has a sufficient stock of different kinds of bags. When the slicer is placed in supermarkets, it must also be avoided that, due to the various operations to be performed, a user, who does not have the required dexterity, monopolizes the slicer too long.

Le document EP 2520501 décrit une trancheuse de denrées qui permet de découper et d'emballer automatiquement une denrée. Néanmoins, cette trancheuse est volumineuse et l'emballage d'une denrée est relativement lent. Dans cette trancheuse, la denrée est déplacée successivement d'une position d'introduction vers une station de coupe et, après que la denrée a été coupée complètement en tranches, elle est dirigée vers une station d'emballage.The document EP 2520501 describes a food slicer that automatically cuts and wraps food. Nevertheless, this slicer is bulky and the packaging of a commodity is relatively slow. In this slicer, the food is successively moved from an introductory position to a cutting station and, after the food has been cut completely into slices, it is directed to a packing station.

L'invention a pour but de réaliser une trancheuse qui permet d'automatiser l'emballage de la denrée après son découpage en tranches et ceci d'une manière beaucoup plus rapide dans une machine très compacte par rapport à l'art antérieur.The object of the invention is to provide a slicer which makes it possible to automate the packaging of the foodstuff after its slicing and this in a much faster manner in a very compact machine compared to the prior art.

A cette fin, une trancheuse suivant l'invention est caractérisée en ce que l'organe d'emballage comporte une unité de fourniture agencée pour fournir de la matière d'emballage à la table de sortie sous forme de deux feuilles orientées l'une vers l'autre de telle façon à ce que les tranches, qui quittent le jeu de lames, viennent se loger entre les deux feuilles, l'organe d'emballage comprenant également un organe de liaison agencé pour lier les feuilles de la matière d'emballage l'une à l'autre sur au moins deux bords opposés l'un à l'autre. L'usage de feuilles de matière d'emballage permet d'éviter d'avoir un stock de sacs d'emballage de différents formats et de devoir choisir à chaque fois le sac adéquat. Les tranches, qui quittent le jeu de lames de coupe, en particulier les tranches formées au moins partiellement dans la partie du pain déjà coupée, viennent se loger entre les feuilles de la matière d'emballage ce qui fait que les tranches sont automatiquement emballées dans les feuilles sans l'intervention de l'utilisateur. La présence de l'organe de maintien veille à ce que les tranches restent ensemble lors de leur mouvement sur la table de sortie et lors de l'emballage. Après que les feuilles ont été appliquées autour des tranches, l'organe de liaison va lier entre elles les feuilles de la matière d'emballage pour ainsi pouvoir fermer l'emballage de la denrée. On constate ainsi que l'emballage est réalisé de façon automatique sans nécessiter l'usage d'un sac.To this end, a slicer according to the invention is characterized in that the packaging member comprises a supply unit arranged to supply packaging material to the output table in the form of two sheets oriented one towards the other such that the slices, which leave the set of blades, are housed between the two sheets, the packaging member also comprising a connecting member arranged to bind the sheets of the packaging material to each other on at least two opposite edges to each other. The use of sheets of packaging material avoids having a stock of packaging bags of different sizes and having to choose each time the appropriate bag. The slices, which leave the set of cutting blades, in particular the slices formed at least partially in the part of the already cut bread, are housed between the sheets of the packaging material so that the slices are automatically packed in the leaves without the intervention of the user. The presence of the holding member ensures that the slices remain together during their movement on the output table and during packaging. After the sheets have been applied around the slices, the connecting member will bind together the sheets of the packaging material to thereby be able to close the packaging of the commodity. It is thus found that the packaging is carried out automatically without requiring the use of a bag.

Une première forme de réalisation d'une trancheuse suivant l'invention est caractérisée en ce que l'organe d'emballage comprend un ensemble de premiers bras reliés à l'unité de fourniture et agencé pour exercer un mouvement de va-et-vient par rapport à la table de sortie et guider la deuxième feuille par rapport aux tranches lorsqu' elles se déplacent sur la table de sortie. Le mouvement de va-et-vient permet de laisser le passage libre pour les tranches lorsqu'elles passent sur la table de sortie et de guider une des feuilles par rapport aux tranches.A first embodiment of a slicer according to the invention is characterized in that the packaging member comprises a set of first arms connected to the supply unit and arranged to move back and forth by report to the output table and guide the second sheet relative to the slices as they move on the output table. The back and forth movement allows the free passage for the slices when they pass on the output table and guide one of the sheets relative to the slices.

La trancheuse de denrées, suivant l'invention, peut être utilisée pour couper différentes denrées, comme du pain ou des cakes. Toutefois, dans le but de simplifier la compréhension de l'invention, cette dernière sera décrite en se limitant à une trancheuse de pain. Il sera, toutefois, clair que la protection conférée n'est pas limitée a une trancheuse de pain. Il en va de même pour la matière d'emballage, qui dans la description sera limitée à du papier. Bien entendu d'autres matières, comme une matière plastique ou de l'aluminium, peuvent également être utilisées en tant que matière d'emballage. La matière d'emballage est, de préférence, formée par du papier thermique, en particulier un papier recouvert d'un film en polyéthylène.The food slicer, according to the invention, can be used to cut various foods, such as bread or cakes. However, for the purpose of simplifying the understanding of the invention, the latter will be described by limiting itself to a bread slicer. It will, however, be clear that the protection conferred is not limited to a bread slicer. The same goes for the packaging material, which in the description will be limited to paper. Of course other materials, such as a plastic or aluminum, can also be used as a packaging material. The packaging material is preferably formed by thermal paper, in particular a paper covered with a polyethylene film.

La trancheuse de pain 1 conventionnelle, illustrée à la figure 1, comporte un jeu de lames de coupe 2 agencé pour couper le pain en tranches. Les lames sont disposées en parallèle et la coupe du pain se fait par un mouvement de va-et-vient des lames lors du passage du pain dans le champ des lames.The conventional bread slicer 1, illustrated in figure 1 , comprises a set of cutting blades 2 arranged to cut the sliced bread. The blades are arranged in parallel and the bread is cut by a movement of back and forth blades when the bread in the field of the blades.

Une table de sortie 4 est disposée en aval du jeu de lames et est agencée pour soutenir les tranches dans leur mouvement lorsqu'elles quittent le jeu de lames. Ainsi, les tranches se déplacent sur la table de sortie ce qui empêche le pain coupé de tomber par terre. La trancheuse peut également comporter un organe d' emballage (non-illustré).An output table 4 is disposed downstream of the blade set and is arranged to support the slices in their movement as they leave the blade set. Thus, the slices move on the exit table which prevents the cut bread from falling to the ground. The slicer may also include a packaging member (not shown).

Un poussoir (non-représenté) est, de préférence, prévu pour pousser le pain 2 à travers le jeu de lames de coupe 2 vers la table de sortie 4. Ce poussoir peut être déplacé entre une position adjacente au jeu de lames 2 et une position éloignée de ce jeu de lames. Ainsi, le pain 1 à couper est introduit dans l'espace entre le jeu de lames et le poussoir lorsque ce dernier est dans sa position éloignée. Afin de couper le pain 1 et de le faire traverser à travers le jeu de lames 2 vers la table de sortie 4, le poussoir est entraîné et déplacé vers sa position adjacente au jeu de lames.A pusher (not shown) is preferably provided to push the bread 2 through the set of cutting blades 2 to the output table 4. This pusher can be moved between a position adjacent to the blade set 2 and a remote position of this blade set. Thus, the bread 1 to be cut is introduced into the space between the set of blades and the pusher when the latter is in its remote position. In order to cut the bread 1 and to pass through the set of blades 2 to the output table 4, the pusher is driven and moved to its position adjacent the set of blades.

Pour éviter que les tranches du pain coupé tombent sous l'effet de la gravité, il est prévu, suivant l'invention, un organe de maintien 5 repris dans les figures 2 et 3. L'organe de maintien est disposé à hauteur de la table de sortie et est agencé pour maintenir les tranches adjacentes les unes des autres dans leur mouvement sur la table de sortie. Cet organe de maintien empêche les tranches de s'écarter l'une de l'autre en appliquant simultanément une légère pression sur deux extrémités opposées du pain dans une direction perpendiculaire au mouvement du pain sur la table de sortie. L'organe de maintien comporte une roue dentée 6 (reprise de façon schématique dans le dessin) sur laquelle sont montées une première 7 et une deuxième 8 crémaillère. La rotation de la roue dentée, qui est entraînée par un moteur (non-illustré), provoque un mouvement de va-et-vient des crémaillères qui sont disposées sous la table de sortie. Des manches 11 et 12 sont montés sur les crémaillères. Un premier doigt 13 et un deuxième doigt 14 sont montés sur le premier 11 respectivement deuxième manche 12 et sont ainsi disposés de part et d'autre de la table de sortie. Les doigts servent à maintenir ensemble les tranches du pain 3. Le mouvement de va-et-vient de la crémaillère va provoquer que les doigts vont arriver aux extrémités du pain pour, ensuite, venir appliquer une pression sur les tranches d'extrémité du pain et les libérer lorsqu'il est arrivé en fin de parcours sur la table de sortie. Bien entendu d' autres formes de réalisation que des doigts peuvent être envisagées telle que par exemple des anneaux, des pastilles, ou des palettes.In order to prevent the slices of cut bread from falling under the effect of gravity, according to the invention, a holding member 5 is provided in the figures 2 and 3 . The holding member is disposed at the height of the output table and is arranged to maintain the adjacent slices of each other in their movement on the output table. This holding member prevents the slices from deviating from each other by simultaneously applying a slight pressure on two opposite ends of the bread in a direction perpendicular to the movement of the bread on the output table. The holding member comprises a toothed wheel 6 (shown schematically in the drawing) on which are mounted a first 7 and a second 8 rack. The rotation of the gearwheel, which is driven by a motor (not shown), causes a reciprocating movement of the racks which are arranged under the output table. Sleeves 11 and 12 are mounted on the racks. A first finger 13 and a second finger 14 are mounted on the first 11 respectively second sleeve 12 and are thus arranged on either side of the output table. The fingers are used to hold together the slices of the bread 3. The movement of back and forth of the rack will cause the fingers will arrive at the ends of the bread to then come to apply pressure on the end slices of the bread and release them when he arrived at the end of the course on the exit table. Of course other embodiments that fingers can be envisaged such as for example rings, pellets, or pallets.

Le document EP 1857233 décrit, par exemple, un tel organe de maintien approprié pour tenir les tranches l'une contre l'autre lors de la découpe du pain et après que ce dernier ait quitté le jeu de lames de coupe.The document EP 1857233 describes, for example, such a holding member suitable for holding the slices against each other during the cutting of the bread and after the latter has left the set of cutting blades.

Lorsque les tranches quittent le jeu de lames de coupe et avancent sur la table de sortie, les crémaillères 7 et 8 seront activées pour permettre de déplacer les doigts 13 et 14 vers les extrémités latérales du pain. Lorsque les doigts entrent en contact avec le pain, le mouvement des crémaillères est arrêté et les doigts appliquent une pression sur le pain pour maintenir les tranches adjacentes les unes des autres.When the slices leave the set of cutting blades and advance on the output table, the racks 7 and 8 will be activated to move the fingers 13 and 14 to the lateral ends of the bread. When the fingers come in contact with the bread, the movement of the racks is stopped and the fingers apply pressure to the bread to maintain the adjacent slices of each other.

Les figures 4 à 6 illustrent le fonctionnement de la trancheuse de pain, suivant l'invention. La trancheuse comporte un organe d'emballage 20 ayant un premier support 21 et un deuxième support 23 sur lequel un premier rouleau de matière d'emballage 22, respectivement un deuxième rouleau de matière d'emballage 24 peut être placé. Il est important que la première feuille 30 et la deuxième feuille 35 soient orientées l'une vers l'autre de telle façon à ce que les tranches qui quittent le jeu de lames viennent se loger entre les deux feuilles.The Figures 4 to 6 illustrate the operation of the bread slicer according to the invention. The slicer includes a packaging member 20 having a first support 21 and a second support 23 on which a first roll of packaging material 22, respectively a second roll of packaging material 24 can be placed. It is important that the first sheet 30 and the second sheet 35 are oriented toward each other so that the slices that leave the set of blades are lodged between the two sheets.

L'organe d'emballage comporte, avantageusement, également un élément d'entraînement agencé pour entrainer la matière d'emballage en provenance du premier rouleau 22 vers la table de sortie 4. Cet élément d'entrainement comporte, de préférence, des rouleaux d'entrainement 26, 27 disposés entre la table de sortie 4 et le jeu de lames de coupe 2, de façon à ce que les rouleaux d'entrainement n'obstruent pas la sortie du pain du jeu des lames de coupe. Les rouleaux d'entrainement sont juxtaposés l'un à l'autre et tournent en sens inverse l'un par rapport à l'autre, de telle façon à entraîner le papier qui est déroulé à partir du rouleau 22. Afin de mieux guider le papier, qui sort des rouleaux d'entraînement, un premier guide 28, 29 est placé de préférence en aval des rouleaux d'entraînement. Le premier guide comporte deux parties qui sont disposées chaque fois dans le prolongement du rouleau auquel la partie du guide est attribuée. Ainsi, une première feuille 30 de papier, qui sort des rouleaux 26 et 27, est guidée par les parties du premier guide 28 et 29 pour être dirigées vers le début de la table de sortie 4.The packaging member advantageously also comprises a drive element arranged to drive the packaging material from the first roller 22 to the output table 4. This drive element preferably comprises roller rollers. 26, 27 arranged between the output table 4 and the set of cutting blades 2, so that the drive rollers do not obstruct the exit of the bread from the clearance of the cutting blades. The drive rollers are juxtaposed with each other and rotate in opposite directions with respect to each other, so as to drive the paper which is unrolled from the roller 22. In order to better guide the paper, which comes out of the drive rollers, a first guide 28, 29 is preferably placed downstream of the drive rollers. The first guide has two parts which are arranged each time in the extension of the roller to which the portion of the guide is allocated. Thus, a first sheet of paper 30 coming out of the rolls 26 and 27 is guided by the portions of the first guide 28 and 29 to be directed towards the beginning of the exit table 4.

L'organe d'emballage comporte également un deuxième guide 31 formé par un rouleau de guidage monté sur un bras 32. Le deuxième guide 31 est disposé au-dessus de la table de sortie en aval du jeu de lames de coupe 2. Le rouleau de guidage est agencé pour guider une deuxième feuille 35 en provenance du deuxième rouleau 24 dans une direction qui s'étend dans le sens du mouvement des tranches quittant le jeu de lames de coupe.The packaging member also comprises a second guide 31 formed by a guide roller mounted on an arm 32. The second guide 31 is disposed above the output table downstream of the set of cutting blades 2. The roller The guide is arranged to guide a second sheet 35 from the second roller 24 in a direction that extends in the direction of movement of the slices leaving the set of cutting blades.

L'organe d'emballage de la trancheuse de denrées comprend également un ensemble de premiers bras 40 agencés pour exercer un mouvement de va-et-vient par rapport à la table de sortie 4 et pour guider la deuxième feuille 35 par rapport aux tranches lorsqu'elles se déplacent sur la table de sortie. Les bras 32 du deuxième guide sont montés sur l'ensemble des premiers bras de telle façon à ce que le deuxième guide 31 subit le mouvement de va-et-vient.The packaging member of the food slicer also comprises a set of first arms 40 arranged to reciprocate with respect to the output table 4 and to guide the second sheet 35 with respect to the slices when they move on the exit table. The arms 32 of the second guide are mounted on the set of first arms so that the second guide 31 is moved back and forth.

Par cette configuration, ledit deuxième guide 31 peut, de préférence, être déplacé suivant une direction essentiellement perpendiculaire par rapport au plan de la table de sortie 4.By this configuration, said second guide 31 can preferably be moved in a direction substantially perpendicular to the plane of the output table 4.

L'organe d'emballage comporte également un organe de coupe 34 agencé pour couper la matière d'emballage. Cet organe de coupe est, de préférence, formé par un couteau en forme de roulette et agencé pour exercer un mouvement de va-et-vient par rapport à la table de sortie. Le couteau est ainsi entraîné dans un mouvement linéaire qui s'étend sur la largeur de la matière d'emballage dans une direction perpendiculaire à celle du mouvement du pain sur la table de sortie. Cet organe de coupe est de préférence placé sous la table de sortie entre les premiers bras 40 et le jeu de lames de coupe 2.The packaging member also comprises a cutting member 34 arranged to cut the packaging material. This cutting member is preferably formed by a wheel-shaped knife and arranged to reciprocate with respect to the exit table. The knife is thus driven into a Linear motion that extends across the width of the wrapping material in a direction perpendicular to that of the bread movement on the output table. This cutting member is preferably placed under the exit table between the first arms 40 and the set of cutting blades 2.

L'organe d'emballage comporte, de préférence, encore un organe de liaison 25 agencé pour lier les feuilles de la matière d'emballage l'une à l'autre. Les feuilles sont reliées entr'elles dans une direction qui est perpendiculaire au mouvement du pain sur la table de sortie. Cet organe de liaison comporte, de préférence, un organe de soudure agencé pour souder les feuilles 30 et 35 l'une à l'autre.The packaging member preferably further comprises a connecting member 25 arranged to bind the sheets of the packaging material to one another. The leaves are connected together in a direction that is perpendicular to the movement of the bread on the exit table. This connecting member preferably comprises a welding member arranged for welding the sheets 30 and 35 to one another.

Pour découper et emballer le pain à l'aide de la trancheuse de pain suivant l'invention, l'utilisateur posera le pain derrière le jeu de lames de coupe 2 pour que le pain puisse être coupé en tranches par le jeu de lames. Lorsque le jeu de lames de coupe sera mis en marche, l'organe d'emballage sera également activé. La mise en marche du jeu de lames de coupe aura comme résultat que le pain commencera à traverser le jeu de lames de coupe. Le jeu des premiers bras 40 sera également activé pour faire monter le deuxième guide 31 et la deuxième feuille de papier qu'il guide, comme illustré à la figure 5. L'élément d'entraînement 26 et 27 sera également activé et ainsi les feuilles de papier 30 et 35 seront déroulées et la deuxième feuille sera élevée. Comme le papier se trouve entre la table de sortie et la sortie du jeu de lames de coupe, la présence de la première feuille aura comme résultat que le pain, au cours de sa découpe, vient se poser sur cette première feuille alors que la présence de la deuxième feuille de papier aura comme résultat que le pain, qui sort du jeu de lames de coupe, viendra se poser devant cette deuxième feuille. Le pain sera ainsi pris entre la première et la deuxième feuille. Donc, au fur et à mesure de la découpe du pain en tranches, celui-ci est introduit entre la première et la deuxième feuille.To cut and package the bread using the bread slicer according to the invention, the user will put the bread behind the set of cutting blades 2 so that the bread can be sliced by the set of blades. When the cutting blade set is turned on, the packing member will also be activated. Turning on the set of cutting blades will result in the bread starting to pass through the set of cutting blades. The game of the first arms 40 will also be activated to raise the second guide 31 and the second sheet of paper that it guides, as shown in FIG. figure 5 . Drive element 26 and 27 will also be activated and thus sheets of paper 30 and 35 will be unwound and the second sheet will be raised. As the paper is between the output table and the output of the cutting blade set, the presence of the first sheet will result in the bread, during its cutting, comes to rest on this first sheet while the presence of the second sheet of paper will result in the bread, which comes out of the game of cutting blades, will come before the second sheet. The bread will be caught between the first and second sheets. Thus, as the bread is cut into slices, it is introduced between the first and the second sheet.

Lorsque les tranches du pain, qui traversent le jeu de lames, commencent à sortir de ce jeu de lames, l'organe de maintien est également activé pour apporter les doigts vers les extrémités latérales du pain. L'organe de maintien suit ou entraîne le parcours du pain sur la table de sortie pour ainsi maintenir les tranches ensemble sur tout leur trajet sur la table de sortie.When the slices of the bread, which pass through the set of blades, begin to come out of this set of blades, the holding member is also activated to bring the fingers towards the lateral ends of the bread. The holding member follows or causes the bread roll on the output table to maintain the slices together on their entire path on the output table.

Le mouvement des vis sans fin et des premiers bras 40 est bien entendu limité par la distance des vis sans fin. Il suffit, en effet, que le deuxième guide 31 soit suffisamment élevée pour qu'il ne gêne pas le mouvement du pain sur la table de sortie. Ainsi, ce mouvement d'élévation des premiers bras, en particulier du deuxième guide 31, est à peine supérieur à la hauteur d'un pain. Arrivé en fin de course, les premiers bras s'arrêteront.The movement of the worm and the first arm 40 is of course limited by the distance of the worm. It suffices, in fact, that the second guide 31 is high enough that it does not interfere with the movement of the bread on the table Release. Thus, this raising movement of the first arms, in particular the second guide 31, is barely greater than the height of a bread. At the end of the race, the first arms will stop.

Dans une forme de réalisation alternative de l'invention, le déplacement du deuxième guide est entraîné par l'action du pain, qui sort du jeu de lames de coupe 2 et qui se déplace sur la table de sortie 4.In an alternative embodiment of the invention, the displacement of the second guide is driven by the action of the bread, which leaves the set of cutting blades 2 and which moves on the output table 4.

Toutefois, puisque le jeu de lames continue son mouvement de coupe tant que le pain n'est pas entièrement coupé, le pain continue à se déplacer sur la table de sortie. Comme le pain a rencontré le papier, le mouvement du pain poussera les feuilles de papier qui continuent ainsi à être déroulées des rouleaux. Le deuxième guide restant en place au-dessus des tranches de pain en mouvement, le mouvement du pain aura comme résultat que la deuxième feuille suivra ce mouvement et ainsi recouvrira le pain. En effet, les tranches de pain passeront sous le deuxième guide, comme illustré à la figure 5. Comme le papier continue à être entraîné et donc déroulé du rouleau, et que la première feuille de papier est sur la table de sortie sous le fond du pain, le mouvement du pain et celui du papier provoquent que le papier enveloppe le pain.However, since the blade set continues its cutting motion until the bread is completely cut, the bread continues to move on the exit table. As the bread has encountered the paper, the movement of the bread will push the sheets of paper that continue to be unrolled rolls. The second guide remaining in place above the slices of bread in motion, the movement of the bread will result in the second leaf following this movement and thus cover the bread. In fact, slices of bread will pass under the second guide, as shown in figure 5 . As the paper continues to be driven and thus rolled out of the roll, and the first sheet of paper is on the output table under the bottom of the bread, the movement of the bread and the paper cause the paper to envelop the bread.

Lorsque le pain est entraîné par un poussoir à travers le jeu de lames, afin d'être coupé en tranches, la partie coupée du pain entraîne la première feuille et la deuxième feuille par l'action du poussoir, de sorte que la matière d'emballage enveloppe le pain au fur et à mesure de son avancement à travers le jeu de lames.When the bread is driven by a pusher through the set of blades, in order to be sliced, the cut portion of the bread causes the first sheet and the second sheet by the action of the pusher, so that the material of wrapping the bread as it progresses through the blade set.

Entretemps, l'organe de maintien 5 tient les tranches l'une contre l'autre par l'intermédiaire des doigts 13 et 14. Après que le poussoir est arrivé dans sa position adjacente au jeu de lame de coupe 2, l'organe de maintien 5, ou au moins les doigts 13 et 14, continuent à se déplacer parallèlement au plan de la table de sortie 4 et s'éloignent du jeu de lames 2 pendant que le pain, coupé en tranches, est tenu par l'organe de maintien entre les doigts 13 et 14. Ainsi, le pain est avancé par l'organe de maintien 5 jusqu'à ce qu'il se trouve à la fin de son parcours à une distance prédéterminée du jeu de lames 2. Lors de l'avancement du pain, celui-ci pousse, de préférence, contre les feuilles 30 et 35 pour l'envelopper entre ces feuilles.Meanwhile, the holding member 5 holds the slices against each other by means of the fingers 13 and 14. After the pusher has arrived in its position adjacent to the cutting blade set 2, the 5, or at least the fingers 13 and 14, continue to move parallel to the plane of the exit table 4 and away from the set of blades 2 while the bread, sliced, is held by the organ of held between the fingers 13 and 14. Thus, the bread is advanced by the holding member 5 until it is at the end of its course at a predetermined distance from the set of blades 2. At the advancement bread, it grows, preferably against the sheets 30 and 35 to wrap between these sheets.

Comme décrit ci-dessus l'organe de maintien 5, grâce à ses doigts 13 et 14, retient les tranches d'extrémité du pain et maintien ensemble donc toutes les tranches se trouvant entre ces tranches d'extrémité, empêchant ainsi le pain coupé de tomber en tranches séparées. L'organe de maintien est agencé pour maintenir les tranches ensemble jusqu'à ce que le pain ait atteint la fin de son trajet sur la table de sortie.As described above, the holding member 5, by virtue of its fingers 13 and 14, retains the end slices of the bread and thus holds together all the slices lying between these end slices, thus preventing the bread cut from fall into separate slices. The holding member is arranged to hold the slices together until the bread has reached the end of its path on the exit table.

A la fin du parcours du pain, ladite distance prédéterminée est au moins égale à la largeur du deuxième guide 31 suivant la direction de déplacement du pain.At the end of the bread run, said predetermined distance is at least equal to the width of the second guide 31 in the direction of movement of the bread.

Lorsque le pain a atteint la fin de son parcours sur la table de sortie et est donc entièrement coupé en tranches, comme illustré à la figure 6, les feuilles de papier couvrent le pain et l'ensemble des premiers bras 40 sera revenu à sa position de départ, achevant ainsi son mouvement de va-et-vient. En particulier, par l'action des premiers bras, ledit deuxième guide 31 descendra jusqu'à ce que la première feuille 30 et la deuxième feuiller 35 se touchent, de préférence, sur toute leur largeur transversalement par rapport à la direction de déplacement du pain. Ensuite, l'organe de liaison 25, qui est de préférence positionné en regard du deuxième guide 31, sera activé (figure 6) et viendra appliquer une première liaison à hauteur où la deuxième feuille rejoint à nouveau la première feuille. La première liaison est appliquée dans une direction perpendiculaire à celle du déplacement du pain sur la table. Ensuite, les feuilles 30 et 35 seront avancées sur une distance située entre 1 et 3 cm de façon à permettre que la première liaison dépasse l'endroit où est situé l'organe de coupure 34.When the bread has reached the end of its course on the exit table and is therefore fully sliced, as shown in figure 6 the sheets of paper cover the bread and the set of first arms 40 will return to its starting position, thus completing its movement back and forth. In particular, by the action of the first arms, said second guide 31 will descend until the first sheet 30 and the second leaf 35 touch, preferably, across their width transversely to the direction of movement of the bread . Then, the connecting member 25, which is preferably positioned opposite the second guide 31, will be activated ( figure 6 ) and will apply a first link at height where the second sheet rejoins the first sheet. The first link is applied in a direction perpendicular to that of the movement of the bread on the table. Then, the sheets 30 and 35 will be advanced over a distance of between 1 and 3 cm so as to allow the first link to go beyond the location where the cutoff member 34 is located.

Il est clair qu'à la fin du parcours du pain, au moins l'organe de liaison 25 est situé entre le pain et le jeu de lames de coupe 2. A ce moment, l'organe de coupure 34 est, de préférence, également situé entre le pain et le jeu de lames.It is clear that at the end of the course of the bread, at least the connecting member 25 is located between the bread and the set of cutting blades 2. At this time, the cutting member 34 is preferably also located between the bread and the blade set.

L'organe de coupure 34 et l'organe de liaison seront maintenant activés pour, d'une part, couper le papier et, d'autre part, appliquer une deuxième liaison. Cette dernière étant appliquée en amont de la première liaison. Ainsi, le déplacement du papier l'organe de coupure se trouve entre la première et la deuxième liaison et la coupure est donc appliquée entre ces deux liaisons. Ceci permet, d'une part, de fermer par la première liaison l'emballage du pain qui vient d'être coupé et, d'autre part, de former par la deuxième liaison une reliure entre les feuilles pour le pain suivant.The cut-off member 34 and the link member will now be activated to first cut the paper and secondly to apply a second link. The latter being applied upstream of the first link. Thus, the movement of the paper cutoff member is between the first and the second link and the cut is therefore applied between these two links. This allows, on the one hand, to close by the first link the packaging of bread that has just been cut and, secondly, to form the second binding binding between the sheets for the next bread.

Apres l'application de la coupure, l'élément d'entraînement fera encore légèrement avancer le papier afin d'apporter suffisamment de papier pour débuter l'emballage du pain suivant.After applying the cut, the drive element will still feed the paper slightly to bring enough paper to begin packing the next bread.

La fermeture des extrémités latérales des feuilles de papier peut se faire manuellement en nouant ou en enroulant ces extrémités. Alternativement, l'organe d'emballage peut également comporter un élément de fermeture agencé pour fermer ces bords latéraux. Cet élément de fermeture comporte, par exemple, un moyen pour coller ou agrafer ces extrémités de façon à le fermer. Les doigts de l'organe de maintien tiennent le pain jusqu' à ce que les côtés latéraux de l'emballage soient fermés pour ensuite s'écarter et revenir en position de repos.The closing of the lateral ends of the paper sheets can be done manually by knotting or wrapping these ends. Alternatively, the packaging member may also comprise a closure element arranged to close these lateral edges. This closure element comprises, for example, a means for gluing or stapling these ends so as to close it. The fingers of the holding member hold the bread until the lateral sides of the package are closed and then move away and return to the rest position.

On constate ainsi que l'emballage ne nécessite pas l'usage de sacs préfabriqués, ni une diversité de sacs, puisque le papier est déroulé à partir d'un rouleau. De plus, l'utilisateur peut, par une simple torsion, nouer les bords latéraux ensemble, étant donné que tout le reste de l'emballage du papier se fait automatiquement, nécessitant ainsi aucune dextérité particulière de l'utilisateur.It is thus noted that the packaging does not require the use of prefabricated bags or a variety of bags, since the paper is rolled from a roll. In addition, the user can, by a simple twist, tie the side edges together, since all the rest of the paper packaging is done automatically, thus requiring no particular dexterity of the user.
