Description

OUTIL ROTATIF DE TRANSFORMATION, CASSETTE ET UNITE DE TRANSFORMATION EQUIPEES AVEC UN TEL OUTIL ROTARY PROCESSING TOOL, CASSETTE AND TRANSFORMATION UNIT EQUIPPED WITH SUCH A TOOL
La présente invention concerne un outil rotatif de transformation pour un support.The present invention relates to a rotary transformation tool for a support.
L'invention se rapporte également à une cassette, avec au moins un outil rotatif de transformation, muni d'un mandrin et d'un manchon amovible porteur d'organes de transformation. L'invention concerne une unité comprenant une cassette, équipée avec au moins un outil rotatif de transformation, muni d'un mandrin et d'un manchon porteur d'organes de transformation. L'invention concerne également une unité, avec au moins un outil rotatif de transformation, muni d'un mandrin et d'un manchon amovible porteur d'organes de transformation. L'invention se rapport enfin à une machine de production d'emballage comprenant une unité de transformation. Une machine de production d'emballages est destinée à la fabrication de boîtes, qui forment des emballages, après pliage et collage. Dans cette machine, un support plan initial, tel qu'une bande continue de carton, est déroulé et est imprimé par une unité d'impression, constituée elle-même de sous-unités sous la forme de groupes imprimeurs. La bande est ensuite transférée dans une unité de découpe. La découpe permet de produire des éléments en plaque, dans ce cas des poses constituées de plusieurs boites rattachées entre-elles. The invention also relates to a cassette, with at least one rotary conversion tool, provided with a mandrel and a removable sleeve carrying transformation members. The invention relates to a unit comprising a cassette, equipped with at least one rotary conversion tool, provided with a mandrel and a sleeve carrying transformation members. The invention also relates to a unit, with at least one rotary conversion tool, provided with a mandrel and a removable sleeve carrying transformation members. The invention finally relates to a packaging production machine comprising a processing unit. A packaging production machine is intended for the manufacture of boxes, which form packaging, after folding and gluing. In this machine, an initial planar support, such as a continuous strip of cardboard, is unwound and is printed by a printing unit, itself constituted of subunits in the form of printing units. The web is then transferred to a cutting unit. Cutting makes it possible to produce plate elements, in this case poses consisting of several boxes attached to one another.
Les poses obtenues présentent des zones de déchets qui forment de chutes de carton qui sont éliminées par éjection. Ces zones sont séparées du reste de la pose grâce à une unité d'éjection des déchets. Les poses sont ensuite envoyées dans un séparateur pour être séparées les unes des autres, afin d'obtenir des boîtes individualisées.  The poses obtained have areas of waste that form cardboard scraps that are removed by ejection. These areas are separated from the rest of the installation by a waste ejection unit. The poses are then sent to a separator to be separated from each other, in order to obtain individualized boxes.
L'unité d'éjection de ces déchets est montée à la suite de l'unité de découpe. L'unité d'éjection assure une éjection précise et rapide des déchets. L'unité d'éjection comprend deux outils, sous la forme de deux cylindres rotatifs, le plus souvent positionnés parallèlement l'un par rapport à l'autre, et l'un au-dessus de l'autre, de façon à coopérer entre eux. Les poses circulent entre les deux cylindres en suivant une trajectoire sensiblement horizontale.  The ejection unit of this waste is mounted following the cutting unit. The ejection unit ensures precise and fast ejection of waste. The ejection unit comprises two tools, in the form of two rotating cylinders, most often positioned parallel to one another, and one above the other, so as to cooperate between them. The poses circulate between the two cylinders in a substantially horizontal trajectory.
L'outil inférieur comporte des aiguilles radiales qui s'enfoncent dans chaque déchet. Les aiguilles séparent les déchets de la pose en les entraînant avec la rotation de ce cylindre inférieur à aiguilles. Les aiguilles sont positionnées sur le cylindre en fonction d'un layout. Ces déchets sont ensuite dégagés de ces aiguilles radiales au cours de la rotation des cylindres. Pour ce faire, des éjecteurs en forme de peignes fixes sont disposés parallèles aux cylindres. Les aiguilles radiales sont ainsi libérées des déchets et s'enfoncent dans d'autres déchets de la pose suivante lors du prochain tour du cylindre. The lower tool has radial needles that sink into each waste. The needles separate the waste from the pose by dragging them with the rotation of this lower needle cylinder. The hands are positioned on the cylinder according to a layout. This waste is then released from these radial needles during the rotation of the cylinders. To do this, ejectors in the form of fixed combs are arranged parallel to the cylinders. The radial needles are thus released from the waste and sink into other waste of the next pose during the next turn of the cylinder.
L'outil supérieur peut aussi avoir à sa surface un revêtement souple de type caoutchouc vulcanisé. Des trous sont percés à différent endroits dans l'outil ou dans le revêtement caoutchouc, selon la version. La position des trous correspond au layout et donc à celle des aiguilles de l'outil inférieur. Ces dernières viennent se loger dans les trous lors de la rotation des deux outils, de façon à bien transpercer les déchets. Les outils supérieur et inférieur assurent le transport des poses et leur maintien lors du piquage des déchets.  The upper tool may also have on its surface a flexible coating vulcanized rubber type. Holes are drilled at different points in the tool or in the rubber liner, depending on the version. The position of the holes corresponds to the layout and therefore to that of the needles of the lower tool. The latter are housed in the holes during the rotation of the two tools, so as to pierce the waste. The upper and lower tools ensure the transport of the poses and their maintenance during the stitching of the waste.
Etat de la technique State of the art
Un seul outil ou les deux outils sont formés avec un mandrin et un manchon amovible. Le manchon s'insère, est bloqué et est entraîné en rotation par le mandrin. Un manchon inférieur avec un mandrin inférieur forment l'outil inférieur et/ou un manchon supérieur avec un mandrin supérieur forment l'outil supérieur. Un manchon amovible est un cylindre creux porteur de la série d'aiguilles. Un autre manchon amovible est un cylindre creux revêtu avec la couche de caoutchouc vulcanisé et dans laquelle sont percés les trous. La légèreté des manchons permet à l'opérateur d'accélérer les changements de travail, plutôt que de changer les outils complets. Les deux outils sont peu coûteux et ne nécessitent au maximum que deux manchons par travail.  A single tool or both tools are formed with a mandrel and a removable sleeve. The sleeve is inserted, locked and rotated by the mandrel. A lower sleeve with a lower mandrel forms the lower tool and / or an upper sleeve with an upper mandrel forms the upper tool. A removable sleeve is a hollow cylinder carrying the series of needles. Another removable sleeve is a hollow cylinder coated with the vulcanized rubber layer and in which the holes are drilled. The lightness of the sleeves allows the operator to accelerate work changes, rather than changing the complete tools. Both tools are inexpensive and require a maximum of two sleeves per job.
On connaît des unités munies de deux outils rotatifs, pour réaliser une découpe rotative (documents WO-2006/1 16,954, EP-0.947.717, WO-93/13,917), un gaufrage (document EP- 1 ,721,742), une éjection des déchets ou une impression. Au moins l'un des deux outils se présente sous la forme d'un mandrin et d'un manchon amovible. Le manchon est porteur d'outils, i.e. respectivement de filets de découpe, de formes de gaufrage, d'aiguilles d'éjection ou d'autres encore.  Units with two rotary tools are known for producing a rotary cut (WO-2006/1 16,954, EP-0,947,717, WO-93 / 13,917), an embossing (EP-1, 721,742), an ejection waste or printing. At least one of the two tools is in the form of a mandrel and a removable sleeve. The sleeve carries tools, i.e. respectively cutting threads, embossing shapes, ejection needles or the like.
Cependant, lors d'un changement de travail pour passer d'un manchon à un autre manchon, l'opérateur doit ouvrir le palier de rotation avant de l'outil, pour dégager l'accès et extraire le manchon. A ce moment là, l'extrémité avant de l'arbre de rotation ou le tourillon avant du mandrin est désolidarisé de son palier avant. Le mandrin avec ou sans manchon est retenu et repose uniquement sur le palier de rotation arrière de l'outil, par l'extrémité arrière de l'arbre de rotation ou le tourillon arrière du mandrin. However, when changing work to move from one sleeve to another sleeve, the operator must open the front rotation bearing of the tool, to clear the access and extract the sleeve. At this time, the front end of the rotating shaft or the front spindle of the mandrel is disengaged from its front bearing. The chuck with or without sleeve is retained and rests only on the rear rotation bearing of the tool, by the rear end of the rotating shaft or the rear spindle of the mandrel.
Le mandrin, avec ou sans manchon, se retrouve en porte-à-faux. Le mandrin se déforme par flexion en raison de son poids auquel se rajoute le poids du manchon, au moment de l'ouverture et de la fermeture du palier. Le mandrin se déforme aussi par flexion en raison de son poids seul, au moment où l'opérateur a fait sortir le manchon devant être changé et avant d'insérer le manchon suivant. La flexion du mandrin amène des désalignements empêchant la bonne sortie ou la bonne introduction du manchon sur le mandrin. De plus, il résulte du poids plus important du mandrin une grande inertie, ce qui pénalise grandement l'entraînement par moteur de l'outil.  The mandrel, with or without sleeve, is found in cantilever. The mandrel deforms by bending because of its weight to which is added the weight of the sleeve, at the time of opening and closing the bearing. The mandrel is also deformed by bending because of its weight alone, when the operator has removed the sleeve to be changed and before inserting the next sleeve. The bending of the mandrel causes misalignments preventing the good output or the good introduction of the sleeve on the mandrel. In addition, it results from the greater weight of the mandrel great inertia, which greatly penalizes the motor drive of the tool.
Exposé de l'invention Presentation of the invention
Un objectif principal de la présente invention consiste à mettre au point un outil avec un mandrin et un manchon amovible porteur d'outils. Un deuxième objectif est de réaliser un mandrin ne se déformant pas lors d'un changement de manchon. Un troisième objectif est d'obtenir un mandrin qui soit à la fois rigide et plus léger pour des questions d'entraînement et pour faciliter sa manipulation. Un quatrième objectif est d'optimiser la précision de fonctionnement d'un outil d'éjection des déchets avec son mandrin et son manchon dans une unité d'éjection des déchets. Un cinquième objectif est d'éviter les inconvénients des unités, des mandrins et des manchons de l'état de la technique. Un autre objectif encore est celui de prévoir une machine de production d'emballages avec une unité d'éjection de déchets intégrée à la suite d'une unité amont de découpe. Conformément à un aspect de la présente invention, un outil rotatif de transformation d'un support comprend un mandrin rotatif et un manchon amovible. Le mandrin est apte à être entraîné en rotation par un moteur d'entraînement en rotation. Le mandrin est muni de deux flasques à chacune des extrémités avant et arrière. Le manchon possède une paroi porteuse d'organes de transformation. Le manchon est reçu, bloqué et entraîné en rotation par le mandrin, de façon à former l'outil rotatif de transformation.  A main objective of the present invention is to develop a tool with a mandrel and a removable sleeve carrying tools. A second objective is to achieve a mandrel not deforming during a change of sleeve. A third objective is to obtain a mandrel that is both rigid and lighter for training and to facilitate handling. A fourth objective is to optimize the operating accuracy of a waste ejection tool with its mandrel and sleeve in a waste ejection unit. A fifth objective is to avoid the disadvantages of units, mandrels and sleeves of the state of the art. Another objective is to provide a packaging production machine with an integrated waste ejection unit following an upstream cutting unit. In accordance with one aspect of the present invention, a rotary tool for converting a support comprises a rotating mandrel and a removable sleeve. The mandrel is adapted to be rotated by a rotary drive motor. The mandrel is provided with two flanges at each of the front and rear ends. The sleeve has a carrier wall of transformation members. The sleeve is received, locked, and rotated by the mandrel to form the rotary transformation tool.
L'outil est caractérisé en ce que le mandrin comprend au moins deux tiges reliant les deux flasques entre-elles. Autrement dit, en remplaçant le mandrin, qui est initialement sensiblement sous la forme d'un cylindre, par deux tiges ou plus de deux tiges, la flèche, qui est la différence maximale de position entre le mandrin et/ou l'outil soumis à la flexion et le mandrin et/ou l'outil au repos, est évitée. La déformation totale de l'outil est très faible, lorsque l'opérateur dégage l'extrémité avant de l'arbre de rotation de l'outil de son palier de rotation, l'outil se retrouvant ainsi en porte-à-faux. La déformation totale du mandrin est très faible, lorsque l'opérateur sort le manchon, le mandrin se retrouvant ainsi en porte- à-faux. The tool is characterized in that the mandrel comprises at least two rods connecting the two flanges together. In other words, by replacing the mandrel, which is initially substantially in the form of a cylinder, by two rods or more than two rods, the arrow, which is the maximum difference in position between the mandrel and / or the tool subjected to bending and the mandrel and / or tool at rest is avoided. The total deformation of the tool is very small, when the operator releases the front end of the rotation shaft of the tool from its rotational bearing, the tool thus being in cantilever. The total deformation of the mandrel is very small, when the operator leaves the sleeve, the mandrel thus being cantilevered.
Le mandrin gagne en légèreté. Le rapport rigidité/masse est augmenté. Le moteur d'entraînement est dimensionné en conséquence d'une plus faible inertie de l'outil, avec mandrin et du manchon, entraîné en rotation. Avec une inertie plus faible, l'outil s'arrête plus rapidement en cas d'urgence. Les tiges servent également de guidage pour le manchon lorsque l'opérateur le retire.  The mandrel gains in lightness. The stiffness / mass ratio is increased. The drive motor is dimensioned as a consequence of a lower inertia of the tool, with chuck and sleeve, driven in rotation. With lower inertia, the tool stops faster in an emergency. The rods also serve as guiding for the sleeve when the operator removes it.
La transformation est définie comme étant une éjection des déchets, une découpe, un gaufrage, une impression, ou d'autres encore. Les sens amont et aval sont définis en faisant référence au sens de déplacement des éléments en plaque, suivant la direction longitudinale dans l'unité d'éjection des déchets et dans l'ensemble de la machine de production d'emballages. La direction longitudinale est définie en faisant référence au sens de déplacement des éléments en plaque dans l'unité d'éjection des déchets et dans la machine, selon son axe longitudinal médian. La direction transversale est définie comme étant la direction perpendiculaire à la direction de déplacement des éléments en plaque. Les positions avant et arrière sont définies par rapport à la direction transversale, comme étant respectivement le côté conducteur ou opérateur et le côté opposé conducteur ou opérateur.  The transformation is defined as waste ejection, cutting, embossing, printing, or others. The upstream and downstream directions are defined with reference to the direction of movement of the plate elements, in the longitudinal direction in the waste ejection unit and in the entire packaging production machine. The longitudinal direction is defined by referring to the direction of movement of the plate elements in the waste ejection unit and in the machine along its median longitudinal axis. The transverse direction is defined as the direction perpendicular to the direction of movement of the plate elements. The front and rear positions are defined relative to the transverse direction as being respectively the driver or operator side and the opposite driver or operator side.

Dans un autre aspect encore de l'invention, une unité de transformation d'un support, du type comprenant un bâti et deux outils rotatifs de transformation coopérant entre eux, au moins l'un des deux outils étant formé avec un mandrin et un manchon amovible, est caractérisée en ce qu'elle comprend une cassette présentant une ou plusieurs des caractéristiques techniques décrites ci-dessous et revendiquées, introduite et fixée au bâti. Une plus faible inertie du mandrin favorise entraînement du système, ainsi que le poids global de la cassette qui doit être mobile.

Exposé détaillé de modes de réalisation préférés Detailed description of preferred embodiments
Comme le montre la Figure 1, une machine de production d'emballages 1 traite un support ou une matière en bande continue 2, qui est dans ce cas du carton plat. La machine 1 comprend une première unité de transformation, par exemple une presse de découpage à platine 3. En amont de la presse 3, la machine 1 peut présenter, des unités telles que des groupes imprimeurs, des moyens pour contrôler la qualité et le registre, des groupes de gaufrage, etc. (non illustrés). La bande 2 rentre dans la presse 3 à l'horizontal par son côté transversal en amont. La presse 3 découpe la bande 2 et délivre le support sous la forme d'élément en plaque, c'est-à-dire de poses en carton plat 4. Les poses 4 sortent de la presse 3 par son côté transversal en aval. Le sens d'avance ou de défilement (Flèches F) de la bande 2 et des poses 4 suivant la direction longitudinale indique le sens amont et le sens aval. As shown in Figure 1, a packaging production machine 1 processes a carrier or a continuous web material 2, which in this case is flat carton. The machine 1 comprises a first processing unit, for example a platen cutting press 3. Upstream of the press 3, the machine 1 can have units such as printing units, means for controlling the quality and the register , embossing groups, etc. (not shown) The band 2 enters the press 3 horizontally by its transverse side upstream. The press 3 cuts the strip 2 and delivers the support in the form of plate element, that is to say poses cardboard flat 4. The poses 4 out of the press 3 by its transverse side downstream. The direction of advance or scroll (arrows F) of the band 2 and poses 4 in the longitudinal direction indicates the upstream direction and the downstream direction.
La machine 1 comprend un agencement d'entraînement 6, qui est disposé en aval de la presse 3. Cet agencement 6 comprend tout d'abord un rouleau d'entraînement inférieur 7, entraîné en rotation par moteur. L'agencement 6 comprend ensuite un seul ou une série de galets presseurs 8, disposés au-dessus en appui contre le rouleau 7. Les poses 4 sont engagées, maintenues et entraînées entre le rouleau 7 et le ou les galets 8. L'agencement 6 assure un transfert actif des poses 4, de façon à dégager les poses 4, successivement les unes après les autres, hors de la presse 3, selon la direction longitudinale F, de l'amont vers l'aval.  The machine 1 comprises a drive arrangement 6, which is disposed downstream of the press 3. This arrangement 6 comprises firstly a lower drive roller 7, rotated by motor. The arrangement 6 then comprises a single or a series of pressure rollers 8 disposed above bearing against the roller 7. The poses 4 are engaged, held and driven between the roller 7 and the roller or rollers 8. The arrangement 6 ensures an active transfer poses 4, so as to clear the poses 4, successively one after the other, out of the press 3, in the longitudinal direction F, from upstream to downstream.
La machine 1 comprend un dispositif de transfert 9 pour les poses 4. Le dispositif 9 est destiné à faire passer vers l'aval les poses 4, successivement les unes après les autres, en provenance de l'agencement 6, selon la direction longitudinale F.  The machine 1 comprises a transfer device 9 for the poses 4. The device 9 is intended to pass downstream the poses 4, successively one after the other, from the arrangement 6, in the longitudinal direction F .
La machine 1 comprend ensuite un premier ensemble de transport, qui est plus spécifiquement un premier transport vacuum 11 , et qui est disposée en aval du dispositif de transfert 9. Ce premier transport vacuum 1 1 comprend un transporteur avec une ou plusieurs courroies sans fin à orifices 12. Un caisson à vacuum 13, connecté à une source de vide, plaque les poses 4 contre la courroie 12.  The machine 1 then comprises a first transport assembly, which is more specifically a first vacuum transport 11, and which is disposed downstream of the transfer device 9. This first vacuum transport 1 1 comprises a conveyor with one or more endless belts with orifices 12. A vacuum box 13, connected to a vacuum source, plates the blanks 4 against the belt 12.
Les poses 4 sont disposées sur la face supérieure de la courroie 12, les unes à la suite des autres, avec un court intervalle entre elles. Le premier transport vacuum 1 1 assure un transfert actif des poses 4. La courroie 12 entraîne les poses 4, selon la direction longitudinale F, de l'amont vers l'aval.  The poses 4 are arranged on the upper face of the belt 12, one after the other, with a short gap between them. The first vacuum transport 1 1 ensures an active transfer poses 4. The belt 12 drives the poses 4, in the longitudinal direction F, from upstream to downstream.
La machine 1 comprend ensuite une deuxième unité de transformation, i.e. une unité d'éjection des déchets 14, qui est placée en aval de la presse 3 et après le premier transport vacuum 1 1. Cette unité 14 permet d'éliminer de manière contrôlée des déchets de carton qui sont prédécoupés dans les poses 4.  The machine 1 then comprises a second processing unit, ie a waste ejection unit 14, which is placed downstream of the press 3 and after the first vacuum transport 1 1. This unit 14 makes it possible to eliminate in a controlled manner cardboard waste that is pre-cut in poses 4.
L'unité d'éjection des déchets 14 comprend une structure porteuse ou un bâti 16. The waste ejection unit 14 comprises a supporting structure or a frame 16.
La partie fonctionnelle de l'unité 14 comprend un premier outil rotatif de transformation inférieur cylindrique 17, coopérant avec un deuxième outil rotatif de transformation supérieur cylindrique 18. Les deux outils 17 et 18 sont montés, parallèles l'un à l'autre, l'un au-dessus de l'autre, et transversalement au bâti 16, et ainsi à l'unité 14. Les poses 4 traversent l'unité 14 en passant entre les deux outils 17 et 18. The functional part of the unit 14 comprises a first cylindrical lower transformation rotary tool 17, cooperating with a second cylindrical upper transformation rotary tool 18. The two tools 17 and 18 are mounted parallel to one another, one above the other, and transversely to the frame 16, and thus to the unit 14. The poses 4 pass through the unit 14 passing between the two tools 17 and 18.
L'outil inférieur 17 est muni d'organes de transformation, i.e. des aiguilles radiales (non visibles), qui font saillie radial ement en direction de l'outil supérieur 18. Ces aiguilles sont positionnées de manière appropriée à la surface de l'outil inférieur 17 aux endroits où le découpage de la bande 2 produit des déchets. Ainsi, ces aiguilles se piquent dans chacune des déchets. Les déchets sont arrachés des poses et entraînés par la rotation de l'outil inférieur 17, et sont éliminés à l'aide de peignes montés à proximité de l'outil inférieur 17.  The lower tool 17 is provided with transformation members, ie radial needles (not visible), which project radially towards the upper tool 18. These needles are appropriately positioned on the surface of the tool lower 17 where the cutting of the strip 2 produces waste. Thus, these needles prick each waste. The waste is torn from the poses and driven by the rotation of the lower tool 17, and are eliminated using combs mounted near the lower tool 17.
L'outil supérieur 18 peut être un cylindre muni d'organes de transformation, i.e. revêtu d'un revêtement en caoutchouc sous la forme d'une couche de caoutchouc souple vulcanisé (non visible). Des trous 19 peuvent être ménagés dans l'outil supérieur 18 dans la couche de caoutchouc. L'extrémité de chacune des aiguilles de l'outil inférieur The upper tool 18 may be a cylinder provided with transformation members, i.e. coated with a rubber coating in the form of a vulcanized soft rubber layer (not visible). Holes 19 may be provided in the upper tool 18 in the rubber layer. The end of each of the needles of the lower tool
17 vient se loger dans un trou 19 de l'outil supérieur 18. 17 is housed in a hole 19 of the upper tool 18.
La machine 1 comprend un deuxième ensemble de transport, qui est plus spécifiquement un deuxième transport vacuum 21, et qui est disposé en aval de l'unité d'éjection des déchets 14. Le deuxième ensemble de transport 21 est sensiblement analogue au premier ensemble de transport 1 1 , avec des courroies sans fin à orifices 12 et un caisson à vacuum 13.  The machine 1 comprises a second transport assembly, which is more specifically a second vacuum transport 21, and which is disposed downstream of the waste ejection unit 14. The second transport assembly 21 is substantially similar to the first set of transport 1 1, with endless belts with orifices 12 and a vacuum box 13.
Le dispositif de transfert 9, le premier transport vacuum 1 1 et le deuxième transport vacuum 21 sont montés dans le bâti 16. L'évacuation des déchets hors de l'unité d'éjection des déchets 14 se fait par aspiration.  The transfer device 9, the first vacuum transport 1 1 and the second vacuum transport 21 are mounted in the frame 16. The disposal of waste out of the waste ejection unit 14 is by suction.
La machine 1 comprend ensuite un séparateur (non représenté), qui est disposé en aval de l'unité d'éjection des déchets 14, après le deuxième ensemble de transport 21. Les points d'attache présents sur les poses 4 et entre les boîtes sont rompus grâce au séparateur, et les poses 4 sont ainsi transformées en boîtes.  The machine 1 then comprises a separator (not shown), which is disposed downstream of the waste ejection unit 14, after the second transport assembly 21. The attachment points present on the poses 4 and between the boxes are broken thanks to the separator, and the poses 4 are thus transformed into boxes.
Dans une forme de réalisation particulièrement favorable (voir Figures 1 et 2), l'unité d'éjection des déchets 14 peut comprendre une cassette amovible 22. Dans cette forme, la cassette 22 est une cassette d'éjection des déchets. La cassette amovible 22 est apte à être introduite dans le bâti 16, à être fixée au bâti 16, et à l'inverse, à être désolidarisée et à être extraite de ce bâti 16.  In a particularly favorable embodiment (see Figures 1 and 2), the waste ejection unit 14 may comprise a removable cassette 22. In this form, the cassette 22 is a waste ejection cassette. The removable cassette 22 is adapted to be inserted into the frame 16, to be fixed to the frame 16, and conversely, to be detached and extracted from the frame 16.
La cassette amovible 22 comprend une structure porteuse ou cadre 23. Comme cela est visible en Figure 2, le cadre 23 est muni d'un palier avant inférieur 24 et d'un palier arrière inférieur 26 portant le premier outil, i.e. l'outil inférieur 17. Le cadre 23 est muni d'un palier avant supérieur 27 et d'un palier arrière supérieur 28 portant le deuxième outil, i.e. l'outil supérieur 18. The removable cassette 22 comprises a supporting structure or frame 23. As can be seen in FIG. 2, the frame 23 is provided with a lower front bearing 24 and a lower rear bearing 26 carrying the first tool, ie the lower tool 17. The frame 23 is provided with an upper front bearing 27 and an upper rear bearing 28 carrying the second tool, ie the upper tool 18.
L'unité 14 comprend un logement transversal ménagé dans le bâti 16 entre le premier ensemble de transport 1 1 et le deuxième ensemble de transport 21. La cassette 22 est introduite transversalement par rapport au bâti 16 dans ce logement transversal. A l'inverse, la cassette 22 peut être extraite transversalement par rapport au bâti 16 hors de ce logement transversal.  The unit 14 comprises a transverse housing formed in the frame 16 between the first transport assembly 1 1 and the second transport assembly 21. The cassette 22 is inserted transversely with respect to the frame 16 in this transverse housing. Conversely, the cassette 22 can be extracted transversely relative to the frame 16 out of this transverse housing.
La cassette 22 comprend des moyens de déplacement transversal, servant également au réglage de sa position transversale dans l'unité 14. Ces moyens sont sous la forme d'une crémaillère 29 faisant saillie au niveau la face avant 31 du cadre 23. La crémaillère 29 est apte à coopérer avec un pignon entraîné par moteur électrique présent au niveau du bâti 16. Des moyens de blocage de la position longitudinale de la cassette 22 par rapport au bâti 16 sont prévus.  The cassette 22 comprises transverse displacement means, also serving to adjust its transverse position in the unit 14. These means are in the form of a rack 29 protruding at the front face 31 of the frame 23. The rack 29 is capable of cooperating with a pinion driven by electric motor present at the frame 16. Locking means of the longitudinal position of the cassette 22 relative to the frame 16 are provided.
La cassette 22 comprend des moyens d'entraînement destinés à entraîner en rotation les deux outils 17 et 18. Ces moyens sont sous la forme d'un premier pignon 32 pour le premier outil 17. Ce premier pignon 32 engrène avec un deuxième pignon 33 pour le deuxième outil 18. L'introduction de la cassette 22 dans le bâti 16 fait engager les dents du premier pignon 32 avec celles d'un pignon conjugué d'un moteur électrique d'entraînement en rotation de l'unité 14.  The cassette 22 comprises drive means intended to drive in rotation the two tools 17 and 18. These means are in the form of a first pinion 32 for the first tool 17. This first pinion 32 meshes with a second pinion 33 for the second tool 18. The introduction of the cassette 22 into the frame 16 causes the teeth of the first gear 32 to engage with those of a conjugate gear of an electric motor driving in rotation of the unit 14.
Au moins l'un des deux outils et ici les deux outils 17 et 18 sont formés avec un mandrin 34 et un manchon cylindrique amovible 36. Seul le deuxième outil 18 a été représenté en Figure 3. Le manchon 36 s'insère (Flèche I en Figure 2), est reçu, se bloque et est entraîné en rotation par le mandrin 34 de l'outil 18. Le manchon 36 se débloque, puis se retire (Flèche R en Figure 2) du mandrin 34. Pour la cassette d'éjection des déchets 22, le manchon de l'outil inférieur d'éjection des déchets 17 est un cylindre creux avec une paroi dans laquelle sont engagées les aiguilles d'éjection des déchets faisant saillies radialement et se déployant vers l'extérieur. Pour la cassette d'éjection des déchets 22, le manchon 36 de l'outil supérieur 18 est un cylindre creux avec une paroi dans laquelle est ménagée la série de trous 19.  At least one of the two tools and here the two tools 17 and 18 are formed with a mandrel 34 and a removable cylindrical sleeve 36. Only the second tool 18 has been shown in Figure 3. The sleeve 36 is inserted (Arrow I in Figure 2), is received, locks and is rotated by the mandrel 34 of the tool 18. The sleeve 36 is unlocked and then withdraws (arrow R in Figure 2) from the mandrel 34. For the cassette of waste ejection 22, the sleeve of the lower waste ejection tool 17 is a hollow cylinder with a wall in which are engaged the radially projecting waste ejecting needles and unfolding outwardly. For the waste ejection cassette 22, the sleeve 36 of the upper tool 18 is a hollow cylinder with a wall in which is formed the series of holes 19.
Pour permettre l'insertion I ou le retrait R et changer le manchon 36 lors d'un changement de travail et d'outils 17 et 18, le palier avant inférieur 24 de l'outil inférieur 17 se dégage en étant inséré dans un bras inférieur 37 mobile par coulissement transversal, puis pivotement dans un plan longitudinal. Le palier avant supérieur 27 de l'outil supérieur 18 se dégage en étant inséré dans un bras supérieur 38 mobile par coulissement transversal, puis pivotement dans un plan longitudinal. To allow the insertion I or withdrawal R and change the sleeve 36 during a change of work and tools 17 and 18, the lower front bearing 24 of the lower tool 17 is disengaged by being inserted into a lower arm 37 movable by sliding transverse, then pivoting in a longitudinal plane. The upper front bearing 27 of the upper tool 18 is disengaged by being inserted into an upper arm 38 movable by transverse sliding, then pivoting in a longitudinal plane.
A son extrémité avant, le mandrin 34 comprend un tourillon avant 39 se déployant transversalement vers l'avant. Le palier avant supérieur 27 vient verrouiller pour rotation le tourillon avant 39 par pivotement et coulissement du bras 38. Le mandrin 34 comprend ensuite une flasque avant 41, sous la forme d'un disque coaxial, rapporté, situé dans un plan orthogonal et dans le prolongement du tourillon avant 39. Le tourillon avant 39 se visse sur la flasque avant 41.  At its front end, the mandrel 34 comprises a front pin 39 extending transversely forwardly. The upper front bearing 27 locks for rotation the front pin 39 by pivoting and sliding the arm 38. The mandrel 34 then comprises a front flange 41, in the form of a coaxial disc, reported, located in an orthogonal plane and in the extension of the front pin 39.

A son extrémité arrière, le mandrin 34 comprend un tourillon arrière 42 se déployant transversalement vers l'arrière. Le tourillon arrière 42 est verrouillé pour rotation au palier arrière supérieur 28. Le tourillon arrière 42 est solidarisé au deuxième pignon 33. Le mandrin 34 est mécaniquement connecté au moteur électrique d'entraînement en rotation par le tourillon arrière 42 et via la pignonnerie 32 et 33. Le mandrin 34 comprend une flasque arrière 43 sous la forme d'un disque coaxial, d'un seul tenant, situé dans un plan orthogonal et dans le prolongement du tourillon arrière 42.  At its rear end, the mandrel 34 comprises a rear pin 42 extending transversely rearwardly. The rear pin 42 is locked for rotation to the upper rear bearing 28. The rear pin 42 is secured to the second pinion 33. The mandrel 34 is mechanically connected to the electric drive motor in rotation by the rear pin 42 and via the pinion 32 and 33. The mandrel 34 comprises a rear flange 43 in the form of a coaxial disc, in one piece, located in an orthogonal plane and in the extension of the rear spigot 42.
Selon l'invention, le mandrin 34 comprend au moins deux tiges 44 reliant les deux flasques 41 et 43 entre-elles. Les tiges 44 sont favorablement disposées en étant parallèles entre-elles. Les tiges sont réparties de manière uniforme à équidistance par rapport à l'axe central de rotation de l'outil 18, du mandrin 34 et du manchon 36. Les tiges restent solidaires de la flasque avant 41 et de la flasque arrière 43.  According to the invention, the mandrel 34 comprises at least two rods 44 connecting the two flanges 41 and 43 to each other. The rods 44 are favorably arranged while being parallel to each other. The rods are uniformly distributed equidistant from the central axis of rotation of the tool 18, the mandrel 34 and the sleeve 36. The rods remain integral with the front flange 41 and the rear flange 43.
Dans le cas illustré dans les Figures 2 à 4, trois tiges 44 sont préférentiellement prévues et sont disposées sensiblement selon un triangle équilatéral vu dans un plan parallèle aux flasques 41 et 43 ou selon les flasques 41 et 43. Les trois tiges 44 sont parallèles entre-elles et s'étendent transversalement sensiblement sur toute la longueur du manchon 36.  In the case illustrated in Figures 2 to 4, three rods 44 are preferably provided and are arranged substantially in an equilateral triangle seen in a plane parallel to the flanges 41 and 43 or flanges 41 and 43. The three rods 44 are parallel between and they extend transversely substantially over the entire length of the sleeve 36.
Le manchon 36 doit être fermement maintenu sur le mandrin 34. Pour ce faire, et dans une forme de réalisation préférée (voir Figure 4), l'outil 18, et ainsi le mandrin 34, comprend une première pièce d'extrémité 46, amovible, et située à l'extrémité avant. La pièce d'extrémité avant 46 est d'un seul tenant avec le tourillon avant 39. Cette pièce d'extrémité avant 46 est coaxiale, tronconique, et possède ainsi une face inclinée arrière, complémentaire d'une face inclinée avant du manchon 36. Il est à noter que dans la vue de la Figure 2, la pièce d'extrémité avant 46 doit être enlevée pour permettre l'insertion I du manchon 36. The sleeve 36 must be firmly held on the mandrel 34. To do this, and in a preferred embodiment (see FIG. 4), the tool 18, and thus the mandrel 34, comprises a first removable end piece 46. , and located at the front end. The front end piece 46 is in one piece with the front spigot 39. This front end piece 46 is coaxial, frustoconical, and thus has a rear inclined face complementary to a front inclined face of the sleeve 36. It should be noted that in the view of Figure 2, the front end piece 46 must be removed to allow the insertion of the sleeve 36.
L'outil 18 et ainsi le mandrin 34 comprend une deuxième pièce d'extrémité, opposée à la pièce d'extrémité avant, fixe et située à l'arrière. De manière favorable, la deuxième pièce d'extrémité arrière est formée par la flasque arrière 43. La flasque arrière 43 est coaxiale, tronconique, et possède ainsi une face inclinée avant complémentaire d'une face inclinée arrière du manchon 36. Lorsque le tourillon avant 39 est vissé sur la flasque avant 41, la pièce d'extrémité avant 46, formant un contre- cône, vient pousser (Flèches T) le manchon 36 contre la flasque arrière 43, formant un cône. La poussée (T) de la pièce d'extrémité avant 46 se fait de façon à bloquer ce manchon 36 sur le mandrin 34.  The tool 18 and thus the mandrel 34 comprises a second end piece, opposite to the front end piece, fixed and located at the rear. Favorably, the second rear end piece is formed by the rear flange 43. The rear flange 43 is coaxial, frustoconical, and thus has a front inclined face complementary to a rear inclined face of the sleeve 36. When the front spigot 39 is screwed onto the front flange 41, the front end piece 46, forming a counter-cone, pushes (arrows T) the sleeve 36 against the rear flange 43, forming a cone. The thrust (T) of the front end piece 46 is made so as to block this sleeve 36 on the mandrel 34.
