- the plate 11a of the leg 11 'upstream of the central pole 10' serves to support the trough 1a, the food roll 1b, and the breaker cylinder 1c.
- This leg 11 ' is preferably aligned with the shaft of the breaker cylinder 1c (see Figure 1).
- the portions 9a, 9b and 9c are metal structures of welded type. More particularly, the bearing posts 10, 10 ', the side jambs 11, 11', and the cross members 12, 12 'of the portions 9a and 9b consist of metal tubes, in particular of steel, assembled by welding.
- the use of hollow element (tubes) advantageously makes it possible to use the elements 10, 10 ', 11, 11', 12 and 12 'of the frame as an air distribution network.

- the height (H) with respect to the ground S of the central axis 5b or 2b of a carding cylinder 5 or 2 is greater than the diameter d of the carding cylinder. In this way, access under the carding cylinder, and in particular access to fairings C is advantageously facilitated.
- the portions 9b upstream of the central portions 9a and / or the portions 9c downstream of the central portions 9a are preferably slidably mounted in translation relative to the ground in a direction transverse to the axis of rotation of the card rolls (machine direction) (see Figure 1 / Arrows D). More particularly, the portions 9b and / or 9c are guided in translation on two parallel rails 14 fixed to the ground.
- This additional feature makes it possible to manually open the card by displacing portions 9b or 9c by translation of the central portions 9a of the frame 9, which advantageously makes it easier to access the carding elements (carding cylinder 5, carding groups 3, fairings C) carried by the central part 9a of the frame 9.
- the card could be a short card which does not have a limb 2 and a communicator 4; the number of outputs of the card is of no importance for the invention, the card could have only one output instead of two upper and lower outputs, or more than two outputs; each card output (downstream of the carding cylinder 5) is not necessarily a doffer type output, but may be of any known type and may for example comprise one or more condenser cylinders.
- FIG. 4 Another embodiment is shown in FIG. 4, in which the frame comprises, for the same carding cylinder 5, two spaced carrier columns 10.
- the frame comprises, for the same carding cylinder 5, two spaced carrier columns 10.
- the carding cylinder 5 has been shown, the other elements of the card (including the satellite carding groups 3 and the fairing C of the carding cylinder) having been omitted.
- each post 10 is slightly offset laterally with respect to the shaft 5a of the calendering roll 5, and therefore is not aligned with said shaft, contrary to the variant of Figures 1 to 3.
- the lateral distance (e) separating the central axis 5b from the carding cylinder 5 and the central axis 10b of a carrying post 10 is preferably less than one third of the diameter d of the carding cylinder. In this way, the lateral size of the frame remains low enough to allow easy access to the carding cylinder, and fairings C.

Description
La présente invention concerne le domaine de l'industrie textile, et a pour objet un nouveau bâti porteur pour machines textiles communément désignées « cardes ».The present invention relates to the field of the textile industry, and relates to a new support frame for textile machines commonly referred to as "cardes".
De manière usuelle une carde comporte une pluralité de cylindres qui sont supportés par un bâti porteur. Au moins un de ces cylindres est un cylindre de cardage qui est plus communément désigné « grand tambour » et qui est pourvu d'une garniture de cardage. A la périphérie de ce cylindre de cardage et en partie haute sont montés des organes cardants satellites. En fonctionnement, les fibres sont introduites à l'entrée de la carde sous la forme d'un matelas de fibres, et sont individualisées à la périphérie du cylindre de cardage (action de cardage) par les actions combinées des organes cardants et de la garniture périphérique du cylindre de cardage.Usually a card has a plurality of cylinders which are supported by a carrier frame. At least one of these cylinders is a carding cylinder which is more commonly referred to as a "big drum" and which is provided with a carding insert. At the periphery of this carding cylinder and at the top are mounted satellite carding members. In operation, the fibers are introduced at the entrance of the card in the form of a fiber mat, and are individualized at the periphery of the carding cylinder (carding action) by the combined actions of the carding members and the trim peripheral of the carding cylinder.
Généralement, et à titre d'exemple non limitatif, les organes cardants sont composés par un ou plusieurs groupes de cardage successifs, chaque groupe de cardage étant composé d'un premier rouleau communément appelé « travailleur » associé à second rouleau communément appelé « débourreur » ou « balayeur ». Dans une autre forme de réalisation, les organes cardants peuvent se présenter sous la forme d'un élément de travail supérieur fixe (encore appelé « plaque cardante ») comportant une pluralité de points cardants fixes à la périphérie du cylindre de cardage.Generally, and by way of non-limiting example, carding members are composed of one or more successive carding groups, each carding group being composed of a first roller commonly called "worker" associated with second roller commonly called "stripper" or "sweeper". In another embodiment, the carding members may be in the form of a fixed upper work element (also called "carding plate") having a plurality of fixed carding points at the periphery of the carding cylinder.
Le bâti porteur doit pouvoir supporter la charge des cylindres ou rouleaux et les contraintes mécaniques découlant de leur rotation. En particulier, le bâti doit pouvoir absorber les vibrations induites par la rotation des différents cylindres ou rouleaux de la carde.The support frame must be able to support the load of the rolls or rollers and the mechanical stresses resulting from their rotation. In particular, the frame must be able to absorb the vibrations induced by the rotation of the various rolls or rolls of the card.
Jusqu'à ce jour, il est considéré dans ce domaine technique que pour répondre à l'objectif précité, il est impératif que le bâti porteur comporte deux parois latérales massives supportant les cylindre porteurs de la carde, tel que le cylindre de cardage, par l'intermédiaire de leurs paliers de roulement montés en bout d'arbre.Until today, it is considered in this technical field that to meet the aforementioned objective, it is imperative that the supporting structure includes two massive side walls supporting the bearing cylinder of the card, such as the carding cylinder, through their rolling bearings mounted at the end of the shaft.
Ces deux parois latérales doivent présenter une résistance mécanique suffisante, et sont généralement en fonte ou en acier. Dans la demande de
Dans la demande de
Dans ces bâtis de l'art antérieur, ces parois latérales rendent difficile l'accès aux organes de la carde, et notamment aux différents carénages de cylindre, et aux interfaces entre cylindres ou rouleaux de la carde. Egalement, les parois latérales du bâti porteur rendent difficile les contrôles visuels de ces organes (par exemple contrôle de leur encrassement, ou encore de leur alignement).In these frames of the prior art, these side walls make it difficult to access the bodies of the card, including the various cylinder fairings, and the interfaces between rolls or rolls of the card. Also, the side walls of the support frame make it difficult visual controls of these bodies (eg control of their fouling, or their alignment).
L'invention vise à proposer une carde dont l'accès (physique ou visuel) aux différents organes, et en particulier au(x) cylindre(s) de cardage de la carde et à leurs carénages, est facilité.The invention aims to propose a card whose access (physical or visual) to the various organs, and in particular to the carding cylinder (s) of the card and their fairings, is facilitated.
Cet objectif est atteint au moyen d'une carde comportant une nouvelle structure de bâti et faisant l'objet des revendications annexées.This objective is achieved by means of a card having a new frame structure and the subject of the appended claims.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description détaillée ci-après d'une variante préférée de réalisation d'une carde de l'invention, laquelle description est donnée à titre d'exemple non limitatif et non exhaustif de l'invention, et en référence au dessins annexés sur lesquels :

On a représenté sur la figure 1 une carde à double sortie, pour la production de non-tissés, et plus particulièrement de non-tissés à base de fibres synthétiques du type polypropylène, polyéthylène,..., et/ou de fibres naturelles du type coton, et/ou de fibres artificielles de type viscose,...FIG. 1 shows a double output card for the production of nonwovens, and more particularly nonwovens based on synthetic fibers of the polypropylene, polyethylene, and / or natural fibers type. cotton type, and / or viscose type artificial fibers, ...
La carde de la figure 1 comprend une entrée 1 de carde constituée de manière usuelle d'une auge 1 a, d'un rouleau alimentaire 1b, et d'un cylindre briseur 1c. Le cylindre briseur 1 c alimente un premier cylindre de cardage rotatif 2, qui est plus communément appelé avant-train, et qui est équipé sur sa périphérie d'une garniture de cardage (sous formes de pointes ou tout autre moyen équivalent) lui permettant de reprendre les fibres de la périphérie du cylindre briseur. De manière usuelle, plusieurs groupes cardants 3 satellites sont montés à la périphérie et en partie supérieure de l'avant-train 2. Chaque groupe cardant 3 est composé d'un rouleau balayeur 3a et d'un rouleau travailleur 3b. Chaque groupe cardant 3 coopère avec l'avant-train 2 et a pour fonction de travailler les fibres prises dans la garniture de l'avant-train 2 en sorte de les individualiser et les paralléliser. Les groupes cardants 3 pourraient être remplacés par tout autre moyen équivalent remplissant la même fonction, et par exemple par des plaques cardantes.The card of FIG. 1 comprises an input 1 of a card made in the usual way of a
En aval de l'avant-train 2, la carde comporte un cylindre de transfert 4, encore communément appelé « communicateur », qui permet de reprendre toutes les fibres à la périphérie de l'avant-train 2 et de les transférer jusqu'à un second cylindre de cardage 5, encore communément appelé « grand tambour ». De manière connue en soi, ce second cylindre de cardage 5 est revêtu d'une garniture de cardage et de manière comparable au premier cylindre de cardage 2 coopère avec des groupes cardants 3.Downstream of the
En aval du second cylindre de cardage 5, la carde comporte deux sorties inférieure et supérieure, chaque sortie de carde comportant un cylindre peigneur 6, un cylindre détacheur 7, et une bande de transport 8.Downstream of the
L'ensemble des cylindres précités de la carde est supporté par un bâti porteur comportant deux structures porteuses latérales 9 identiques montées en vis-à-vis l'une de l'autre, chaque structure porteuse latérale 9 étant, dans l'exemple particulier illustré, composée de trois parties distinctes : une partie centrale 9a, une partie 9b en amont de la partie centrale, et une partie 9c en aval de la partie centrale 9a.All of the aforementioned cylinders of the card is supported by a support frame comprising two identical
Les parties centrales 9a des structures porteuses latérales 9 supportent le cylindre de cardage 5, le carénage C de ce cylindre, et les groupes cardants 3 satellites montés en partie supérieure de ce cylindre. Les parties 9b des structures porteuses latérales 9 supportent le cylindre de cardage 2 (avant-train), les groupes cardants 3 satellites montés en partie supérieure de ce cylindre, le cylindre communicateur 4, l'auge 1a, le rouleau alimentaire 1b, le cylindre briseur 1c, et les carénages C associés aux cylindres 2, 4 et 1c. Les parties 9c des structures porteuses latérales 9 supportent les éléments de carde positionné en aval du cylindre de cardage 5 (dans l'exemple particulier illustré : cylindres peigneurs 6, rouleaux détacheurs 7, bande de transport 8).The
Sur la figure 3, on a représenté uniquement les deux parties principales 9a et 9b de l'une des structures porteuses 9, la partie 9c n'étant pas représentée. La structure des parties principales 9a et 9b va à présent être détaillée.In FIG. 3, only the two
En référence à la figure 3, chaque partie 9a comporte un poteau central porteur 10 vertical, deux jambages latéraux 11 verticaux , positionnés symétriquement de part et d'autre du poteau porteur 10, chaque jambage 11 étant relié rigidement au poteau porteur 10 par une traverse 12 horizontale. Les bases du poteau porteur 10 et des jambages latéraux 11 sont fixées sur une plaque d'embase 13, qui est montée sur un rail 14 fixé au sol.With reference to FIG. 3, each
En référence aux figures 2 et 3, le poteau porteur 10 comporte un plateau supérieur 10a formant un plan porteur horizontal. Sur ce plan porteur horizontal est fixé par exemple au moyen d'une bride (non représentée) un palier de roulement 15 traversé par l'arbre 5a du cylindre de cardage 5. Les deux poteaux porteurs 10 sont alignés avec l'arbre 5a du cylindre de cardage 5. Par « alignés », on signifie dans le présent texte que les poteaux porteurs 10 sont positionnés à l'aplomb de l'arbre du cylindre (sans être nécessairement centrés sur l'axe de rotation de cet arbre). De la sorte, les deux poteaux porteurs 10 des structures latérales 9 en vis-à-vis supportent le cylindre de cardage 5 respectivement aux deux extrémités de l'arbre 5a de ce cylindre, et reprennent ainsi verticalement toute la charge du cylindre de cardage 5 au niveau de l'arbre de ce cylindre.Referring to Figures 2 and 3, the
De préférence, les deux poteaux porteurs 10 sont centrés sur ledit arbre 5a. Par «centrés » on signifie dans le présent texte que l'axe central vertical 10b (figure 1) de chaque poteau porteur 10 est situé sensiblement dans le même plan vertical que l'axe central de rotation 5b de l'arbre 5a.Preferably, the two
Sur chaque poteau porteur 10 est en outre fixé un flasque latéral 16 vertical. De manière connue en soi, les rouleaux balayeur 3a et travailleur 3b des groupes cardants satellites 3 sont supportés en rotation par les deux flasques latéraux 16. De la sorte, les deux poteaux porteurs 10 des structures latérales 9 en vis-à-vis supportent également les groupes cardants satellites 3 montés en périphérie haute du cylindre de cardage 5.On each
Les jambages 11 ont pour fonction de stabiliser verticalement le poteau porteur 10 dans un plan vertical et orthogonal à l'axe de rotation 5b du cylindre de cardage 5 (plan de la figure 1).The
En référence aux figures 1 et 3, chaque partie 9b du bâti est identique à la partie 9a précédemment décrite, en ce qu'elle comporte un poteau central porteur 10' qui reprend verticalement la charge de l'avant-train 2 et de ses groupes cardants satellites 3 en étant aligné avec, et de préférence centré sur, l'arbre de rotation 2a de l'avant-train 2. Chaque poteau porteur 10' est stabilisé latéralement par deux jambages verticaux 11', reliés rigidement au poteau porteur 10' par des traverses 12'.With reference to FIGS. 1 and 3, each
De manière additionnelle, chaque jambages 11' de la partie 9b comporte un plateau supérieur 11a formant un plan horizontal. Le plateau 11a du jambage 11' en aval du poteau central 10' sert de support au cylindre communicateur 4. Ce jambage 11' est aligné avec l'arbre 4a de ce cylindre 4, et est de préférence centré sur l'arbre 4a. Le plateau 11a du jambage 11' en amont du poteau central 10' sert de support à l'auge 1a, au rouleau alimentaire 1b, et au cylindre briseur 1c. Ce jambage 11' est de préférence aligné avec l'arbre du cylindre briseur 1c (voir figure 1).Additionally, each leg 11 'of
De préférence, les parties 9a, 9b et 9c sont des structures métalliques de type mécano soudée. Plus particulièrement, les poteaux porteurs 10, 10', les jambages latéraux 11, 11', et les traverses 12,12' des parties 9a et 9b sont constituées de tubes métalliques, notamment en acier, assemblés par soudage. L'utilisation d'élément creux (tubes) permet avantageusement d'utiliser les éléments 10,10', 11,11', 12 et 12' du bâti comme réseau de distribution d'air. Lorsque le bâti sert de réseau de distribution d'air, un ventilateur (non représenté) est par exemple monté sur le poteau porteur 10 ou 10', et est raccordé aérauliquement avec la cavité intérieure de ce poteau 10 ou 10', au moins une ouverture (d'évacuation en cas de soufflage, ou d'admission en cas d'aspiration) étant prévue sur l'un des éléments tubulaire du bâti, et par exemple en partite haute du poteau porteur 10 ou 10'.Preferably, the
Avantageusement selon l'invention, la structure tubulaire du bâti porteur permet un accès (visuel ou physique) aisé aux organes de la carde, ce qui simplifie les opérations de contrôle, maintenance, et nettoyage de la carde.Advantageously according to the invention, the tubular structure of the support frame allows easy access (visual or physical) to the bodies of the card, which simplifies the operations of control, maintenance, and cleaning of the card.
De préférence, la hauteur (H) par rapport au sol S de l'axe central 5b ou 2b d'un cylindre de cardage 5 ou 2 est supérieure au diamètre d du cylindre de cardage. De la sorte, l'accès sous le cylindre de cardage, et en particulier l'accès aux carénages C est avantageusement facilité.Preferably, the height (H) with respect to the ground S of the
Selon une autre caractéristique additionnelle du bâti de carde 9 de l'invention, les parties 9b en amont des parties centrales 9a et/ou les parties 9c en aval des parties centrales 9a sont de préférence montées coulissantes en translation par rapport au sol dans une direction transversale à l'axe de rotation des cylindres de carde (direction machine) (voir figure 1/ Flèches D). Plus particulièrement les parties 9b et/ou 9c sont guidées en translation sur deux rails parallèles 14 fixés au sol. Cette caractéristique additionnelle permet d'ouvrir manuellement la carde en écartant par translation les parties 9b ou 9c des parties centrales 9a du bâti 9, ce qui permet avantageusement d'accéder plus facilement aux éléments de carde (cylindre de cardage 5, groupes cardants 3, carénages C) portés par la partie centrale 9a du bâti 9.According to another additional feature of the
L'invention n'est pas limitée à l'exemple particulier de carde qui vient d'être décrite, mais s'applique d'une manière générale à tout type de carde. En particulier, mais de manière non exhaustive, la carde pourrait être une carde courte ne comportant pas d'avant-train 2 et de communicateur 4 ; le nombre de sorties de la carde est sans importance pour l'invention ;la carde pourrait ne comporter qu'une seule sortie au lieu de deux sorties supérieure et inférieure, ou plus de deux sorties ; chaque sortie de carde (en aval du cylindre de cardage 5) n'est pas nécessairement une sortie de type peigneur, mais peut être de tout type connu et peut par exemple comporter un ou plusieurs cylindres condenseurs.The invention is not limited to the particular example of the card which has just been described, but generally applies to any type of card. In particular, but in a non-exhaustive manner, the card could be a short card which does not have a
On représenté sur la figure 4, une autre variante de réalisation dans laquelle, le bâti comporte, pour un même cylindre de cardage 5, deux poteaux porteurs 10 espacés. Sur cette figure 4, par soucis de simplification, seul le cylindre de cardage 5 a été représenté, les autres éléments de la carde (notamment les groupes cardants satellites 3 et le carénage C du cylindre de cardage) ayant été omis.Another embodiment is shown in FIG. 4, in which the frame comprises, for the
Dans cette variante de réalisation de la figure 4, les deux poteaux porteurs 10 sont reliés rigidement à leur sommet par un plateau porteur horizontal (P), qui supportant l'arbre 5a du cylindre de cardage, et sont en outre relié rigidement à proximité de leur base par une traverse T. Dans cette variante, chaque poteau 10 est légèrement décalé latéralement par rapport à l'arbre 5a du cylindre de calandrage 5, et de ce fait n'est pas aligné avec ledit arbre, contrairement à la variante des figures 1 à 3 . Dans ce cas, la distance latérale (e) qui sépare l'axe central 5b du cylindre de cardage 5 et l'axe central 10b d'un poteau porteur 10 est de préférence inférieure à un tiers du diamètre d du cylindre de cardage. De la sorte, l'encombrement latéral du bâti reste suffisamment faible pour permettre l'accès facilité au cylindre de cardage, et aux carénages C.In this embodiment of Figure 4, the two
