Description

Domaine TechniqueTechnical Field

La présente invention se rapport au domaine général des supports de coupe à aspiration pour machine de coupe automatique de matériaux en feuilles, notamment de matériaux textiles, à l'aide d'une lame vibrante pénétrant dans le support de coupe. Elle concerne plus précisément un dispositif permettant d'assembler un tel élément de support de coupe sur une latte d'une machine de coupe à convoyeur.The present invention relates to the general field of suction-feed cutting supports for automatic sheet material cutting machines, particularly for textile materials, using a vibrating blade that penetrates the cutting support. More specifically, it relates to a device for assembling such a cutting support element onto a slat of a conveyor-type cutting machine.

Un domaine d'application de l'invention est celui de la découpe automatique de piles ou de matelas de feuilles de matériaux, notamment de matériaux textiles, à l'aide d'une lame vibrante pénétrant dans un support de coupe à aspiration.One area of application of the invention is the automatic cutting of stacks or mattresses of sheet materials, in particular textile materials, using a vibrating blade penetrating a suction cutting support.

Technique antérieurePrevious technique

Une machine de coupe à lame vibrante comprend notamment un convoyeur de coupe qui sert à entraîner la pile de feuilles durant l'opération de coupe. Ce convoyeur de coupe est logé dans un caisson à l'intérieur duquel est établie une forte dépression afin de maintenir immobiles les feuilles de matériau à découper durant l'opération de coupe.A vibrating blade cutting machine includes a cutting conveyor that carries the stack of sheets during the cutting operation. This cutting conveyor is housed in a chamber where a strong vacuum is created to hold the sheets of material to be cut in place during the cutting process.

Dans ce type de machine, le convoyeur de coupe sert également de support de coupe pénétrant pour la lame vibrante. Il est en effet bien connu de rendre le support de coupe pénétrable par la lame de sorte que durant l'opération de coupe, la lame puisse non seulement traverser complètement le matériau à couper, mais également s'étendre vers le bas au-delà de la surface de support et dans le lit de matériau fournissant une telle surface.In this type of machine, the cutting conveyor also serves as a penetrating cutting support for the vibrating blade. It is indeed well known that the cutting support is designed to be penetrable by the blade so that during the cutting operation, the blade can not only completely penetrate the material to be cut, but also extend downwards beyond the support surface and into the material bed, thus providing such a surface.

Pour ce faire, le support de coupe est généralement constitué d'un assemblage de pavés montés sur des lattes de support de coupe qui sont elles-mêmes installées dans le convoyeur et entraînées par une courroie. Plus précisément, chaque pavé comprend une pluralité de poils montés sur une semelle en plusieurs rangées parallèles, chaque poil ayant une tête formant le support pour le matériau en feuilles à découper. Des canaux transversaux sont pratiqués au travers de la semelle pour permettre le passage de l'air d'aspiration. Ces pavés permettent ainsi de supporter le matériau à découper sous aspiration tout en pouvant être pénétrés par la lame de coupe.To achieve this, the cutting support typically consists of an assembly of blocks mounted on cutting support slats, which are themselves installed in the conveyor and driven by a belt. More specifically, each block comprises a number of bristles mounted on a base in several parallel rows, each bristle having a head that forms the support for the sheet material to be cut. Transverse channels are cut through the base to allow the passage of suction air. These blocks thus support the material to be cut under suction while still allowing penetration by the cutting blade.

Alternativement, des supports de coupe réalisés par le montage d'une pluralité d'éléments modulaires de peigne sur des lattes de support de coupe ont été développés. On pourra notamment se référer à la publication WO 2021/191522 qui décrit un exemple de réalisation d'éléments modulaires de peigne comprenant une pluralité de poils arrangés selon une même et unique ligne, ce qui permet de donner à au moins certains poils une tête présentant une section droite englobant une section droite de la tige, tout en conservant la faculté de fabriquer ces éléments modulaires par moulage en une seule pièce avec leur semelle et leurs poils. Une telle forme géométrique des poils présente ainsi l'avantage de limiter les interactions entre la pointe de la lame de coupe et les poils en tangence.Alternatively, cutting supports made by mounting a plurality of modular comb elements onto cutting support slats have been developed. Reference may be made, in particular, to the publication WO 2021/191522 This describes an example of modular comb components comprising a plurality of bristles arranged along a single line. This allows at least some bristles to have a head with a straight cross-section encompassing a straight cross-section of the shaft, while still allowing these modular components to be manufactured by molding in a single piece, including their base and bristles. This geometric shape of the bristles thus has the advantage of limiting interactions between the cutting blade tip and the bristles in tangency.

Quel que soit leur mode de réalisation, les pavés ou les éléments modulaires de peigne sont généralement assemblés sur les lattes de support de coupe par l'intermédiaire d'attaches en forme de crochets qui viennent s'insérer dans des glissières formées dans les lattes.Regardless of how they are made, the modular comb blocks or elements are generally assembled onto the cutting support slats by means of hook-shaped fasteners which fit into grooves formed in the slats.

La conséquence de ce type d'assemblage est qu'il est nécessaire de démonter complètement les lattes installées dans le convoyeur dès que l'on souhaite extraire un pavé endommagé (ou un élément modulaire de peigne) pour le remplacer par un nouveau. Le remplacement d'un pavé (ou d'un élément modulaire de peigne) est ainsi rendu particulièrement fastidieux.The consequence of this type of assembly is that it is necessary to completely dismantle the slats installed in the conveyor whenever a damaged block (or comb module) needs to be removed and replaced with a new one. Replacing a block (or comb module) is therefore particularly cumbersome.

Exposé de l'inventionDescription of the invention

La présente invention a donc pour but de proposer un dispositif d'assemblage d'un élément modulaire de support de coupe sur une latte de support de coupe qui ne présente pas les inconvénients précités.The present invention therefore aims to provide a device for assembling a modular cutting support element onto a cutting support slat which does not present the aforementioned disadvantages.

Conformément à l'invention, ce but est atteint grâce à un dispositif d'assemblage d'un élément modulaire de support de coupe sur une latte de support de coupe d'une machine de coupe à convoyeur pour la découpe de matériaux en feuilles, comprenant :

  • une latte de support de coupe destinée à être solidaire d'un convoyeur de la machine de coupe,
  • au moins un élément modulaire de support de coupe comprenant une pluralité de poils chacun ayant un pied solidaire d'une semelle et une tête opposée au pied sur laquelle est destinée à reposer un matériau en feuilles à découper, et
  • des moyens de maintien vertical par magnétisme d'au moins une partie de la semelle de l'élément modulaire de support de coupe sur au moins une partie de la latte de support de coupe.
According to the invention, this goal is achieved by means of an assembly device for a modular cutting support element on a cutting support slat of a conveyor cutting machine for cutting sheet materials, comprising:
  • a cutting support slat intended to be attached to a conveyor of the cutting machine,
  • at least one modular cutting support element comprising a plurality of bristles, each having a foot attached to a sole and a head opposite the foot on which a sheet material to be cut is intended to rest, and
  • means of vertically maintaining by magnetism at least a part of the base of the modular cutting support element on at least a part of the cutting support slat.

Le dispositif selon l'invention est remarquable en ce que le maintien vertical de l'élément modulaire de support de coupe (à savoir pavé de support de coupe ou élément modulaire de peigne) s'effectue par magnétisme. Lorsqu'il est nécessaire d'extraire l'élément modulaire de support de coupe de la latte de support de coupe (par exemple pour le remplacer par un élément modulaire neuf), celui-ci est simplement tiré verticalement pour annuler l'effet magnétique et le désolidariser de la latte de support de coupe. En particulier, ce dispositif permet d'assurer un démontage d'un élément modulaire de support de coupe sans avoir à démonter au préalable la latte de support de coupe, l'élément modulaire de support de coupe étant maintenu en position sur la latte que par magnétisme et par un crochet.The device according to the invention is remarkable in that the vertical retention of the modular cutting support element (namely, the cutting support pad or modular comb element) is achieved magnetically. When it is necessary to remove the modular cutting support element from the cutting support slat (for example, to replace it with a new modular element), it is simply pulled vertically to cancel the magnetic effect and detach it from the cutting support slat. In particular, this device allows for the removal of a modular cutting support element without having to first remove the cutting support slat, as the modular cutting support element is held in position on the slat solely by magnetism and a hook.

De façon avantageuse, la latte de support de coupe comprend à une première extrémité latérale un crochet et la semelle de l'élément modulaire de support de coupe comprend à une première extrémité latérale un crochet apte à coopérer avec le crochet de la latte de support de coupe pour assurer le maintien latéral et vertical de l'élément modulaire de support de coupe sur la latte de support de coupe.Advantageously, the cutting support slat includes at one lateral end a hook and the base of the modular support element of The cutting unit includes at a first lateral end a hook suitable for cooperating with the hook of the cutting support slat to ensure the lateral and vertical retention of the modular cutting support element on the cutting support slat.

Dans cette configuration, la première extrémité latérale du dispositif permet le maintien en latéral et en vertical de l'élément modulaire de support de coupe sur la latte et s'oppose aux efforts que subit l'élément modulaire de support de coupe pendant toutes les phases de fonctionnement.In this configuration, the first lateral end of the device allows the modular cutting support element to be held laterally and vertically on the slat and opposes the forces that the modular cutting support element undergoes during all phases of operation.

De façon avantageuse également, le dispositif comprend en outre des moyens de maintien latéral d'une seconde extrémité latérale de la semelle de l'élément modulaire de support de coupe contre une seconde extrémité latérale de la latte de support de coupe.Advantageously, the device also includes means for laterally holding a second lateral end of the base of the modular cutting support element against a second lateral end of the cutting support slat.

Dans ce cas, la seconde extrémité latérale de la semelle de l'élément modulaire de support de coupe peut comprendre un ergot en saillie et la seconde extrémité latérale de la latte de support peut comprendre une butée en saillie apte à coopérer avec l'ergot de la semelle de l'élément modulaire de support de coupe de façon à permettre un maintien latéral de la seconde extrémité latérale de la semelle de l'élément modulaire de support de coupe contre la seconde extrémité latérale de la latte de support de coupe.In this case, the second lateral end of the base of the modular cutting support element may include a projecting lug and the second lateral end of the support slat may include a projecting stop suitable for cooperating with the lug of the base of the modular cutting support element so as to allow lateral support of the second lateral end of the base of the modular cutting support element against the second lateral end of the cutting support slat.

Alternativement, la seconde extrémité latérale de la semelle de l'élément modulaire de support de coupe peut comprendre une encoche en retrait et la seconde extrémité latérale de la latte de support peut comprendre une butée en saillie apte à coopérer avec l'encoche de la semelle de l'élément modulaire de support de coupe de façon à permettre un maintien latéral de la seconde extrémité latérale de la semelle de l'élément modulaire de support de coupe contre la seconde extrémité latérale de la latte de support de coupe.Alternatively, the second lateral end of the base of the modular cutting support element may include a recessed notch and the second lateral end of the support slat may include a projecting stop suitable for cooperating with the notch in the base of the modular cutting support element so as to permit lateral retention of the second lateral end of the base of the modular cutting support element against the second lateral end of the cutting support slat.

Selon un mode de réalisation, la semelle de l'élément modulaire de support de coupe comprend un aimant positionné au moins à sa seconde extrémité latérale et la latte de support de coupe comprend un insert métallique positionné au moins à sa seconde extrémité latérale de façon à permettre un maintien vertical par magnétisme de la seconde extrémité latérale de la semelle de l'élément modulaire de support de coupe sur la seconde extrémité latérale de la latte de support de coupe.According to one embodiment, the base of the modular cutting support element includes a magnet positioned at least at its second lateral end, and the cutting support slat includes a metal insert positioned at least at its second lateral end so as to allow for retention vertical by magnetism of the second lateral end of the base of the modular cutting support element on the second lateral end of the cutting support slat.

Dans ce cas, l'aimant de la semelle de l'élément modulaire de support de coupe peut être commun pour une pluralité d'éléments modulaires de support de coupe adjacents.In this case, the magnet on the base of the modular cutting support element can be common for a plurality of adjacent modular cutting support elements.

De plus, l'aimant peut s'étendre entre les deux extrémités latérales de l'élément modulaire de support de coupe et être muni de perçages pour le passage d'air.In addition, the magnet can extend between the two lateral ends of the modular cutting support element and be equipped with holes for air passage.

Description des modes de réalisationDescription of the implementation methods

La présente invention concerne des supports de coupe pour convoyeur de coupe à aspiration d'une machine de coupe automatique par lame de matériaux en feuilles.The present invention relates to cutting supports for a suction-feed cutting conveyor of an automatic sheet material cutting machine.

Typiquement, un convoyeur de coupe sert à entraîner la pile de feuilles durant l'opération de coupe. Ce convoyeur de coupe est généralement logé dans un caisson à l'intérieur duquel est établie une forte dépression afin de maintenir immobiles les feuilles de matériau à découper durant l'opération de coupe.Typically, a cutting conveyor is used to move the stack of sheets during the cutting operation. This cutting conveyor is usually housed in a box inside which a strong vacuum is created to hold the sheets of material to be cut in place during the cutting operation.

Par ailleurs, le convoyeur de coupe sert de support de coupe pénétrant pour la lame vibrante. Il est en effet nécessaire de rendre le support de coupe pénétrable par la lame de sorte que durant l'opération de coupe, la lame puisse non seulement traverser complètement le matériau à couper, mais également s'étendre vers le bas au-delà de la surface de support et dans le lit de matériau fournissant une telle surface.Furthermore, the cutting conveyor serves as a penetrating cutting support for the vibrating blade. It is indeed necessary to make the cutting support penetrable to the blade so that during the cutting operation, the blade can not only completely pass through the material to be cut, but also extend downwards beyond the support surface and into the material bed providing such a surface.

Comme représenté sur la figure 1, le convoyeur de coupe comprend généralement une pluralité de supports de coupe 2-1 composés chacun d'un pavé de support de coupe 4-1 qui est monté sur une latte de support de coupe 6-1, celle-ci étant elle-même installée dans le convoyeur et entraînée par une courroie.As depicted on the figure 1 , the cutting conveyor generally comprises a plurality of cutting supports 2-1, each consisting of a cutting support block 4-1 which is mounted on a cutting support slat 6-1, the latter being itself installed in the conveyor and driven by a belt.

Le pavé de support de coupe 6-1 peut être remplacé par un élément unitaire de peigne comme décrit en détails dans la demande de brevet WO 2021/191522 dont le contenu est intégré ici par voie de référence.The 6-1 cutting support pad can be replaced by a unit comb element as described in detail in the patent application WO 2021/191522 the content of which is incorporated here by way of reference.

De façon plus précise, chaque pavé de support de coupe 4-1 (ou élément unitaire de peigne) comprend une pluralité de poils 8 ayant chacun un pied 8a monté sur une semelle 10-1 en formant une ou plusieurs rangées parallèles de poils, et une tête 8b opposée au pied et sur laquelle est destinée à reposer le matériau en feuilles à découper. De façon connue, la semelle 10-1 est munie de perçages (non représentés sur les figures) permettant le passage de l'air d'aspiration.More precisely, each cutting support block 4-1 (or unit element of the comb) comprises a plurality of bristles 8, each having a foot 8a mounted on a sole 10-1 in one or more parallel rows of bristles, and a head 8b opposite the foot on which the sheet material to be cut rests. As is known, the sole 10-1 is provided with perforations (not shown in the figures) allowing the passage of suction air.

Selon l'invention, chaque pavé de support de coupe 4-1 (ou élément unitaire de peigne) est assemblé sur une latte de support de coupe 6-1, à une première extrémité latérale par des moyens mécaniques de maintien latéral et vertical, et à une seconde extrémité latérale (opposée à la première extrémité), d'une part par des moyens de maintien vertical par magnétisme et, d'autre part, par des moyens mécaniques de maintien latéral.According to the invention, each cutting support block 4-1 (or unit element of comb) is assembled on a cutting support slat 6-1, at a first lateral end by mechanical means of lateral and vertical retention, and at a second lateral end (opposite to the first end), on the one hand by means of vertical retention by magnetism and, on the other hand, by mechanical means of lateral retention.

Dans les modes de réalisation des figures 1 à 3, la première extrémité latérale des pavés de support de coupe 6-1 correspond à leur extrémité amont par rapport au sens d'avance F du convoyeur de la machine de coupe, et la seconde extrémité latérale correspond à leur extrémité aval (toujours dans le sens d'avance F du convoyeur).In the modes of embodiment of figures 1 to 3 , the first lateral end of the cutting support blocks 6-1 corresponds to their upstream end with respect to the direction of advance F of the cutting machine conveyor, and the second lateral end corresponds to their downstream end (still in the direction of advance F of the conveyor).

Toujours dans ces différents modes de réalisation, les moyens mécaniques de maintien latéral et vertical au niveau de la première extrémité latérale des pavés de support de coupe 6-1 sont formés par coopération entre des crochets complémentaires.In these different embodiments, the mechanical means for lateral and vertical retention at the level of the first lateral end of the cutting support blocks 6-1 are formed by cooperation between complementary hooks.

Plus précisément, la première extrémité latérale 6a de la latte de support de coupe 6-1 est munie d'un crochet 12 au niveau de sa face supérieure qui est ouvert vers l'aval (par rapport au sens d'avance F du convoyeur).More specifically, the first lateral end 6a of the cutting support slat 6-1 is provided with a hook 12 at its upper face which is open downstream (relative to the direction of advance F of the conveyor).

De même, le pavé de support de coupe 4-1 (ou de l'élément unitaire de peigne) est muni, au niveau de la face inférieure de la première extrémité latérale 10a de sa semelle 10-1, d'un crochet 14 qui est ouvert vers l'amont et qui coopère avec le crochet 12 de la latte de support de coupe pour assurer un maintien mécanique du pavé de support de coupe à la fois latéralement et verticalement.Similarly, the 4-1 cutting support block (or the comb unit element) is equipped, at the underside of the first end lateral 10a of its sole 10-1, of a hook 14 which is open upstream and which cooperates with the hook 12 of the cutting support slat to ensure mechanical support of the cutting support block both laterally and vertically.

Au niveau de la seconde extrémité latérale 6a de la latte de support de coupe, le maintien vertical du pavé de support de coupe s'effectue par magnétisme.At the second lateral end 6a of the cutting support slat, the vertical retention of the cutting support block is achieved by magnetism.

Dans le mode de réalisation de la figure 1, ce maintien par magnétisme est réalisé au moyen, d'une part d'un insert métallique 16 qui est positionné au niveau de (voire intégré dans) la face inférieure de la seconde extrémité latérale 10b de la semelle 10-1 du pavé de support de coupe (ou de l'élément unitaire de peigne), et d'autre part par un aimant 18 qui est positionné au niveau de (voire intégré dans) la face supérieure de la seconde extrémité latérale 6a de la latte de support 6-1.In the implementation of the figure 1 , this magnetic retention is achieved by means of, on the one hand, a metal insert 16 which is positioned at the level of (or even integrated into) the lower face of the second lateral end 10b of the sole 10-1 of the cutting support pad (or of the unit element of the comb), and on the other hand, a magnet 18 which is positioned at the level of (or even integrated into) the upper face of the second lateral end 6a of the support slat 6-1.

Ainsi, l'aimant 18 et l'insert métallique 16 coopèrent entre eux par magnétisme pour permettre un maintien vertical du pavé de support de coupe (ou de l'élément unitaire de peigne) sur la latte de support de coupe au niveau de leur seconde extrémité latérale respective.Thus, the magnet 18 and the metal insert 16 cooperate with each other by magnetism to allow vertical retention of the cutting support pad (or the unit element of the comb) on the cutting support slat at the level of their respective second lateral end.

On notera que, lorsqu'il s'agit d'un pavé de support de coupe, l'insert métallique ne s'étend pas nécessairement sur toute la longueur de celui-ci (il peut ne couvrir qu'une partie de la longueur du pavé de support de coupe).It should be noted that, when it comes to a cutting support block, the metal insert does not necessarily extend over its entire length (it may only cover part of the length of the cutting support block).

De plus, lorsqu'il s'agit d'une pluralité d'éléments unitaires de peigne, il faudra prévoir un insert métallique pour chaque élément unitaire de peigne.Furthermore, when dealing with a plurality of unit comb elements, a metal insert will be required for each unit comb element.

Toujours dans ce mode de réalisation, le maintien latéral du pavé de support de coupe 4-1 sur la latte de support de coupe 6-1 s'effectue des moyens mécaniques.In this embodiment, the lateral support of the cutting support block 4-1 on the cutting support slat 6-1 is achieved by mechanical means.

A cet effet, dans le mode de réalisation de la figure 1, la seconde extrémité latérale 10b de la semelle 10-1 du pavé de support de coupe 4-1 comprend un ergot 20 qui est en saillie vers l'intérieur, et la seconde extrémité latérale 6b de la latte de support 6-1 comprend une butée 22 qui est en saillie vers l'extérieur et qui est apte à coopérer avec l'ergot 20 de la semelle du pavé de support de coupe de façon à permettre un maintien latéral mécanique du pavé de support de coupe contre la latte de support de coupe au niveau de leur seconde extrémité latérale respective.To this end, in the implementation method of the figure 1 , the second lateral end 10b of the sole 10-1 of the cutting support block 4-1 includes a lug 20 which projects inwards, and the second lateral end 6b of the support slat 6-1 includes a stop 22 which projects outwards and which is adapted to cooperate with the lug 20 of the sole of the support block. cut in such a way as to allow lateral mechanical support of the cutting support block against the cutting support slat at the level of their respective second lateral end.

En liaison avec la figure 2, on décrira maintenant un autre mode de réalisation du dispositif d'assemblage 2-2 selon l'invention.In connection with the figure 2 , we will now describe another embodiment of the 2-2 assembly device according to the invention.

Ce mode de réalisation se distingue de celui précédemment décrit par les moyens de maintien vertical par magnétisme de la seconde extrémité latérale 10b' de la semelle 10-2 du pavé de support de coupe 4-2 (ou de l'élément unitaire de peigne) sur la seconde extrémité latérale 6b' de la latte de support de coupe 6-2.This embodiment differs from the one previously described by the means of vertically maintaining by magnetism the second lateral end 10b' of the sole 10-2 of the cutting support block 4-2 (or of the unit element of the comb) on the second lateral end 6b' of the cutting support slat 6-2.

En effet, dans cet autre mode de réalisation, le maintien par magnétisme est réalisé au moyen, d'une part d'un insert métallique 16' qui est positionné au niveau de (voire intégré dans) la face inférieure de la seconde extrémité latérale 6a' de la latte de support 6-2, et d'autre part par un aimant 18' qui est positionné au niveau de (voire intégré dans) la face supérieure de la seconde extrémité latérale 10b' de la semelle 10-2 du pavé de support de coupe (ou de l'élément unitaire de peigne).Indeed, in this other embodiment, the magnetic retention is achieved by means of, on the one hand, a metallic insert 16' which is positioned at the level of (or even integrated into) the lower face of the second lateral end 6a' of the support slat 6-2, and on the other hand, a magnet 18' which is positioned at the level of (or even integrated into) the upper face of the second lateral end 10b' of the base 10-2 of the cutting support block (or of the unit element of the comb).

Il s'agit donc d'une configuration aimant-insert métallique qui est inverse par rapport à celle décrite en liaison avec le mode de réalisation de la figure 1.This is therefore a magnet-metal insert configuration that is the inverse of that described in connection with the embodiment of the figure 1 .

Par ailleurs, dans ce mode de réalisation, l'aimant 18' peut s'étendre entre les deux extrémités latérales 10b' de la semelle 10-2 du pavé de support de coupe (ou de l'élément unitaire de peigne). Dans ce cas, l'aimant sera également muni de perçages pour permettre le passage d'air d'aspiration.Furthermore, in this embodiment, the magnet 18' can extend between the two lateral ends 10b' of the base 10-2 of the cutting support block (or the comb unit element). In this case, the magnet will also be provided with holes to allow the passage of suction air.

En liaison avec la figure 3, on décrira maintenant encore un autre mode de réalisation du dispositif d'assemblage 2-3 selon l'invention.In connection with the figure 3 , we will now describe yet another embodiment of the assembly device 2-3 according to the invention.

Ce mode de réalisation se distingue des deux précédents par les moyens de maintien latéral du pavé de support de coupe 4-3 sur la latte de support de coupe 6-3 au niveau de leur seconde extrémité latérale respective.This embodiment differs from the two previous ones by the means of lateral retention of the cutting support block 4-3 on the cutting support slat 6-3 at the level of their respective second lateral end.

En effet, dans ce mode de réalisation, la seconde extrémité latérale 10b" de la semelle 10-3 du pavé de support de coupe 4-3 (ou de l'élément unitaire de peigne) comprend une encoche 24 sur sa face intérieure qui est en retrait et la seconde extrémité latérale 6b" de la latte de support 6-3 comprend une butée 26 qui est en saillie vers l'extérieur et qui est apte à coopérer avec l'encoche 24 de la semelle du pavé de support de coupe de façon à permettre un maintien latéral du pavé de support de coupe contre la latte de support de coupe au niveau de leur seconde extrémité latérale respective.Indeed, in this embodiment, the second lateral end 10b" of the base 10-3 of the cutting support block 4-3 (or of the unit element of comb) includes a notch 24 on its inner face which is recessed and the second lateral end 6b" of the support slat 6-3 includes a stop 26 which is projecting outwards and which is able to cooperate with the notch 24 of the base of the cutting support pad so as to allow lateral retention of the cutting support pad against the cutting support slat at their respective second lateral ends.

On notera que dans ce mode de réalisation, les moyens de maintien vertical par magnétisme de la seconde extrémité latérale 10b" de la semelle 10-3 du pavé de support de coupe 4-3 (ou de l'élément unitaire de peigne) sur la seconde extrémité latérale 6b" de la latte de support de coupe 6-3 peuvent être similaires à ceux décrits en liaison avec la figure 1 (et comme représenté sur la figure 3) ou, alternativement, être similaires à ceux décrits en liaison avec la figure 2.It should be noted that in this embodiment, the means for vertically retaining, by magnetism, the second lateral end 10b" of the base 10-3 of the cutting support block 4-3 (or the unit element of the comb) on the second lateral end 6b" of the cutting support slat 6-3 can be similar to those described in connection with the figure 1 (and as depicted on the figure 3 ) or, alternatively, be similar to those described in connection with the figure 2 .

En liaison avec la figure 4, on décrira maintenant encore un autre mode de réalisation du dispositif d'assemblage 2-4 selon l'invention.In connection with the figure 4 , we will now describe yet another embodiment of the assembly device 2-4 according to the invention.

Dans ce mode de réalisation, le maintien vertical par magnétisme de la semelle 10-4 du pavé de support de coupe 4-4 (ou de l'élément unitaire de peigne) sur la latte de support de coupe 6-4 est réalisé notamment par un aimant 28 qui est positionné au niveau de (voire intégré dans) la face inférieure de la semelle du pavé de support de coupe (ou de l'élément unitaire de peigne) sur toute la largeur de celui-ci (c'est-à-dire entre ses deux extrémités latérales).In this embodiment, the vertical holding by magnetism of the sole 10-4 of the cutting support block 4-4 (or of the unit element of the comb) on the cutting support slat 6-4 is achieved in particular by a magnet 28 which is positioned at the level of (or even integrated into) the lower face of the sole of the cutting support block (or of the unit element of the comb) over its entire width (i.e. between its two lateral ends).

De plus, un insert métallique 30 est positionné au niveau de (voire intégré dans) la face supérieure de la latte de support 6-4 sur toute la largeur de celui-ci (c'est-à-dire entre ses deux extrémités latérales).In addition, a metal insert 30 is positioned at the level of (or even integrated into) the upper face of the support slat 6-4 over its entire width (i.e. between its two lateral ends).

Ainsi, l'aimant 28 et l'insert métallique coopèrent entre eux par magnétisme pour assurer un maintien du pavé de support de coupe 4-4 (ou de l'élément unitaire de peigne) sur la latte de support de coupe 6-4.Thus, the magnet 28 and the metal insert cooperate with each other by magnetism to ensure that the cutting support pad 4-4 (or the unit element of the comb) is held on the cutting support slat 6-4.

Bien entendu, dans ce mode de réalisation, l'aimant 28 de la semelle du pavé de support de coupe 4-4 (ou de l'élément unitaire de peigne) est muni de perçages (non représentés sur la figure) pour permettre le passage d'air d'aspiration.Of course, in this embodiment, the magnet 28 of the base of the cutting support pad 4-4 (or of the unit element of the comb) is provided with holes (not shown in the figure) to allow the passage of suction air.

Par ailleurs, dans ce mode de réalisation, le dispositif d'assemblage est dépourvu de crochet au niveau de la première extrémité latérale du pavé de support de coupe 4-4 (ou de l'élément unitaire de peigne) et de la latte de support de coupe 6-4.Furthermore, in this embodiment, the assembly device is devoid of a hook at the first lateral end of the cutting support block 4-4 (or the unit element of the comb) and the cutting support slat 6-4.

De même, le dispositif d'assemblage de ce mode de réalisation est dépourvu de moyens mécaniques pour assurer un maintien latéral d'une seconde extrémité latérale de la semelle du pavé de support de coupe (ou de l'élément unitaire de peigne) contre une seconde extrémité latérale de la latte de support de coupe.Similarly, the assembly device of this embodiment lacks mechanical means to ensure lateral support of a second lateral end of the base of the cutting support block (or the unit element of the comb) against a second lateral end of the cutting support slat.

En effet, dans ce mode de réalisation, la seule force magnétique d'attraction de l'aimant 38 permet d'assurer cette fonction de maintien latéral en plus du maintien vertical.Indeed, in this embodiment, the sole magnetic force of attraction of the magnet 38 makes it possible to ensure this lateral support function in addition to the vertical support.

Bien entendu, dans ce mode de réalisation, il est possible d'envisager une disposition inverse de l'aimant et de l'insert métallique, c'est-à-dire d'avoir l'aimant intégré à la surface supérieure de la latte de support de coupe, et l'insert métallique intégré à la surface inférieure du pavé de support de coupe (ou de l'élément unitaire de peigne).Of course, in this embodiment, it is possible to consider an inverse arrangement of the magnet and the metal insert, that is to say, to have the magnet integrated into the upper surface of the cutting support slat, and the metal insert integrated into the lower surface of the cutting support pad (or the unit element of the comb).

En liaison avec la figure 5, on décrira maintenant encore un autre mode de réalisation du dispositif d'assemblage 2-5 selon l'invention.In connection with the figure 5 , we will now describe yet another embodiment of the assembly device 2-5 according to the invention.

Ce mode de réalisation se distingue de celui précédemment décrit en ce que la semelle 10-5 du pavé de support de coupe 4-5 (ou de l'élément unitaire de peigne) comprend, entre ses deux extrémités latérales, un doigt 32 faisant saillie vers l'intérieur et apte à venir se loger dans une encoche 34 formée dans la latte de support de coupe 6-5 de façon à assurer un arrêt en translation du pavé de support de coupe (ou de l'élément unitaire de peigne).This embodiment differs from the one previously described in that the base 10-5 of the cutting support block 4-5 (or of the unit element of the comb) includes, between its two lateral ends, a finger 32 projecting inwards and adapted to fit into a notch 34 formed in the cutting support slat 6-5 so as to ensure a translational stop of the cutting support block (or of the unit element of the comb).

Bien entendu, il est possible d'envisager une disposition inverse avec le doigt porté par la latte de support de coupe et venant se loger dans une encoche formée dans le pavé de support de coupe afin d'assurer l'arrêt en translation.Of course, it is possible to consider an inverse arrangement with the finger carried by the cutting support slat and fitting into a notch formed in the cutting support block in order to ensure the stop in translation.

De même, il est possible d'envisager une disposition inverse entre l'aimant 28 et l'insert métallique 30, à savoir un aimant intégré à la latte de support de coupe et l'insert métallique intégré au pavé de support de coupe.Similarly, it is possible to consider an inverse arrangement between the magnet 28 and the metal insert 30, namely a magnet integrated into the cutting support slat and the metal insert integrated into the cutting support pad.

Par ailleurs, quel que soit le mode de réalisation, la première extrémité latérale 10b, 10b', 10b" de la semelle 10-1 à 10-5 du pavé de support de coupe 4-1 à 4-5 (ou de l'élément unitaire de peigne) comprend avantageusement des moyens d'identification sans contact. Par exemple, ces moyens peuvent être un tag RFID permettant d'identifier individuellement ou par lot le pavé de support de coupe (ou l'élément unitaire de support de coupe, le cas échéant).Furthermore, regardless of the embodiment, the first lateral end 10b, 10b', 10b" of the sole 10-1 to 10-5 of the cutting support pad 4-1 to 4-5 (or of the comb unit element) advantageously includes contactless identification means. For example, these means may be an RFID tag allowing individual or batch identification of the cutting support pad (or the cutting support unit element, as applicable).

On notera également que, quel que soit le mode de réalisation, la semelle 10-1 à 10-5 du pavé de support de coupe 4-1 à 4-5 (ou de l'élément unitaire de peigne) est munie de perçages pour permettre le passage de l'air d'aspiration, de sorte qu'il est nécessaire que la face supérieure de la latte de support de coupe 6-1 à 6-5, l'insert métallique et l'aimant utilisés pour assurer le maintien par magnétisme soient également munis de perçages pour le passage de l'air d'aspiration (ou bien qu'ils soient agencés pour permettre ce passage d'air).It should also be noted that, regardless of the embodiment, the base 10-1 to 10-5 of the cutting support block 4-1 to 4-5 (or of the unit element of the comb) is provided with holes to allow the passage of suction air, so that it is necessary that the upper face of the cutting support slat 6-1 to 6-5, the metal insert and the magnet used to ensure magnetic retention are also provided with holes for the passage of suction air (or that they are arranged to allow this passage of air).
