Description

L'invention a pour objet une installation pour le traitement comme un lavage, un blanchiment, une teinture, un séchage ou analogue de pièces de matières textiles au moyen d'un fluide de traitement dans un appareil comprenant une enceinte externe munie d'un circuit réversible de fluide de traitement et au moins un porte-matières sur lequel sont placées les pièces à traiter, propre à pénétrer et/ou sortir dudit appareil pour le chargement et/ou le déchargement desdites pièces dans et hors de l'appareil dont l'enceinte externe comprend au moins une porte d'entrée et de sortie du porte-matières, avec des moyens de guidage de ce dernier prévus au voisinage du fond de l'appareil et des moyens de déplacement dudit porte-matières sur lesdits moyens de guidage.The subject of the invention is an installation for the treatment such as washing, bleaching, dyeing, drying or the like of pieces of textile material by means of a treatment fluid in an apparatus comprising an external enclosure provided with a circuit. reversible treatment fluid and at least one material carrier on which the parts to be treated are placed, suitable for entering and / or leaving said device for loading and / or unloading said pieces in and out of the device, the external enclosure comprises at least one entry and exit door of the material carrier, with means for guiding the latter provided in the vicinity of the bottom of the apparatus and means for moving said material carrier on said guide means.

Elle vise, en particulier, une installation pour le traitement de matières textiles par circulation au travers desdites matières d'un liquide ou bain, par exemple, et sans que cette indication ait quelque caractère limitatif que ce soit, un bain de lavage, de blanchiment, de teinture ou analogue, ou encore un traitement de séchage à l'aide d'un fluide gazeux comme de l'air.It relates, in particular, to an installation for the treatment of textile materials by circulation through said materials of a liquid or bath, for example, and without this indication having any limiting nature whatsoever, a washing, bleaching bath. , dye or the like, or a drying treatment using a gaseous fluid such as air.

La Demanderesse a déjà proposé, par exemple, dans FR-A-2 450 147 une installation comportant un porte-matières sur lequel sont empilées des bobines d'une matière textile à traiter dont le chargement et/ou le déchargement s'effectue par piles de bobines. Une installation de ce type est également connue par DE-A-2 300 838 qui prévoit aussi un chargement et/ou un déchargement du porte-matières pile par pile de bobines, ce qui constitue un progrès appréciable par rapport aux installations plus anciennes dans lesquelles ces opérations sont exécutées bobine par bobine. Ces opérations de chargement et/ou de déchargement sont néanmoins relativement longues, en particulier lorsque les porte-matières sont prévus pour un nombre de piles important, comme cela est le cas dans les installations modernes.The Applicant has already proposed, for example, in FR-A-2 450 147 an installation comprising a material carrier on which are spools of textile material to be treated, the loading and / or unloading is carried out by batteries of coils. An installation of this type is also known from DE-A-2 300 838 which also provides for loading and / or unloading of the material carrier stack by stack of coils, which constitutes appreciable progress compared to older installations in which these operations are performed coil by coil. These loading and / or unloading operations are nevertheless relatively long, in particular when the material carriers are provided for a number of batteries. important, as is the case in modern installations.

En outre, dans ces installations connues comportant un appareil de traitement à cuve cylindrique d'axe vertical les porte-matières et/ou le porte-matières et l'ensemble de la cuve de traitement sont mis en place par des moyens de levage à palans, portique ou pont roulant lesquels, relativement encombrants, nécessitent pour leur utilisation des bâtiments à hauteur sous plafond suffisante, voir par exemple, FR-A-2 003 379.In addition, in these known installations comprising a treatment device with a cylindrical tank with a vertical axis, the material carriers and / or the material carrier and the whole of the treatment vessel are put in place by lifting means with hoists. , gantry or overhead crane which, relatively bulky, require buildings with sufficient height under ceiling for their use, see for example, FR-A-2 003 379.

Aux inconvénients rappelés ci-dessus des installations connues s'ajoute encore le fait que les procédés de traitement mis en oeuvre dans ces installations prévoient généralement une immersion totale des piles de bobines dans le bain utilisé, de sorte que celui-ci exige un volume qui peut être de l'ordre de dix fois celui de la matière pour remplir la totalité de l'appareil de traitement.In addition to the drawbacks mentioned above of known installations, there is also the fact that the treatment methods implemented in these installations generally provide for total immersion of the coil stacks in the bath used, so that the latter requires a volume which can be of the order of ten times that of the material to fill the entire processing apparatus.

Pour s'affranchir de ces inconvénients on a déjà proposé, par exemple dans EP-Al-0 110 058, un autoclave propre à recevoir un ou plusieurs porte-matières qui peuvent être introduits et/ou extraits de l'autoclave, au moyen de chariots, chaque porte-matières présentant une multiplicité de tiges verticales sur lesquelles sont enfilées, dans le cas de bobines, les matières textiles à traiter. Avec un tel autoclave le traitement s'effectue à rapport de bain de l'ordre de 1: 6 et si le chargement et/ou le déchargement de l'autoclave à l'aide des porte-matières est plus simple que dans certaines installations connues, le document cité est muet quant à la manière de charger lesdits porte-matières. En outre, l'entrée ou la sortie de bain se fait latéralement, de sorte qu'un traitement du type "non-immergé" n'est pas possible.To overcome these drawbacks, an autoclave has already been proposed, for example in EP-Al-0 110 058, capable of receiving one or more material carriers which can be introduced and / or extracted from the autoclave, by means of trolleys, each material carrier having a multiplicity of vertical rods on which are threaded, in the case of spools, the textile materials to be treated. With such an autoclave the treatment is carried out at a bath ratio of the order of 1: 6 and if the loading and / or unloading of the autoclave using the material carriers is simpler than in certain known installations. , the cited document is silent as to how to load said material carriers. In addition, the entry or exit of the bath is done laterally, so that treatment of the "non-submerged" type is not possible.

Par rapport à cet état de la technique, l'invention a pour objet de fournir une installation pour le traitement, à l'aide d'un fluide, de matières textiles sur un porte-matières qui pallient les inconvénients des installations connues d'une part et, d'autre part accroisse encore les caractéristiques de productivité par rapport aux installations comportant un autoclave du type de celui décrit immédiatement ci-dessus, tout en permettant des traitements non possibles par cet autoclave.Compared to this state of the art, the object of the invention is to provide an installation for the treatment, using a fluid, of textile materials. on a material carrier which overcomes the drawbacks of known installations on the one hand and, on the other hand, further increases the productivity characteristics compared to installations comprising an autoclave of the type described immediately above, while allowing treatments not possible with this autoclave.

C'est, en particulier, un but de l'invention de fournir une installation pour le traitement, à l'aide d'un fluide, de matières textiles sur des porte-matières qui n'exige pas d'être abritée dans des bâtiments trop importants et qui, ainsi, peut trouver application dans des unités de taille plus modeste que celles équipées des appareillages connus.It is, in particular, an object of the invention to provide an installation for the treatment, using a fluid, of textile materials on material carriers which does not require to be sheltered in buildings too large and which, therefore, can find application in units of more modest size than those equipped with known apparatus.

C'est, enfin, un but de l'invention de fournir une installation pour le traitement, à l'aide d'un fluide, de matières textiles sur des porte-matières qui, tout en réduisant de façon considérable les coûts de traitement par rapport aux procédés et installations connus, conduisent cependant à des produits finis de même qualité ou de qualité supérieure à celle des produits obtenus par les procédés et installations de l'art antérieur.It is, finally, an object of the invention to provide an installation for the treatment, using a fluid, of textile materials on material carriers which, while considerably reducing the costs of treatment by compared to known processes and installations, however, lead to finished products of the same quality or of higher quality than the products obtained by the processes and installations of the prior art.

On se réfère d'abord à la figure 1 qui montre, de façon très schématique, une installation selon l'invention pour le traitement, à l'aide d'un fluide, de matières textiles sur des porte-matières et dans le cas d'une installation de traitement de bobines ou analogues.Reference is first made to FIG. 1 which very schematically shows an installation according to the invention for the treatment, using a fluid, of textile materials on material carriers and in the case of an installation for processing coils or the like.

Une telle installation comprend un poste A de bobinage et de filature, un poste B de chargement des bobines issues du poste A sur un porte-matières, un appareil C de traitement des matières textiles sous forme de bobines de fils, de mèches, de rubans ou analogues, un poste D de déchargement des porte-matières à leur sortie de l'appareil C et un poste E où lesdites matières textiles traitées sont reprises pour une opération ultérieure.Such an installation comprises a station A for winding and spinning, a station B for loading the bobbins from station A onto a material carrier, an apparatus C for processing textile materials in the form of bobbins of threads, rovings, ribbons or the like, a station D for unloading the material carriers at their exit from the apparatus C and a station E where said treated textile materials are taken up for a subsequent operation.

Selon l'invention, les bobines 2 issues des moyens de bobinage et de filature A sont positionnées sur un module de stockage 11 placé préalablement au début du chargement des bobines 2 sur un chariot 7, figures 1, 2 et 3.According to the invention, the coils 2 from the winding and spinning means A are positioned on a storage module 11 placed prior to the start of loading the coils 2 on a carriage 7, FIGS. 1, 2 and 3.

Dans la forme de réalisation décrite et représentée, ledit module est à contour plan rectangulaire et comprend des moyens de partition et de préhension 16 définissant en plan un dessin à rangées et colonnes de piles de trois, quatre ou cinq bobines, chacune d'axe 11c à l'intersection d'une ligne et d'une colonne.In the embodiment described and shown, said module has a rectangular plan outline and comprises partition and gripping means 16 defining in plan a drawing with rows and columns of stacks of three, four or five coils, each of axis 11 c at the intersection of a row and a column.

Comme bien visible sur les figures 4a et 4b, chaque pile de bobines 2 repose sur une embase tubulaire 10 dont un décrochement 10a est propre à coopérer avec un moyen 16 de préhension des piles. Tous les moyens 16 de partition et de préhension sont solidarisés à leur partie supérieure par une grille rigide 16a, figure 2, à laquelle est associé, en partie haute, un oeil 11d, figure 2 qui, lorsque le module garni de bobines est amené par le chariot 7 au poste B, permet le chargement simultané sur un porte-matières 1 de l'ensemble des bobines d'un module.As clearly visible in FIGS. 4 a and 4 b , each stack of coils 2 rests on a tubular base 10, a recess 10 a of which is capable of cooperating with a means 16 for gripping the batteries. All the partition and gripping means 16 are secured at their upper part by a rigid grid 16 a , FIG. 2, with which is associated, in the upper part, an eye 11 d , FIG. 2 which, when the module fitted with coils is brought by the carriage 7 to station B, allows simultaneous loading on a material carrier 1 of all the coils of a module.

De façon plus précise, chaque pile de bobines est embrochée par le canal axial qu'elle présente sur une clarinette à tube perforé ou une baïonnette 13 à profil en étoile dont l'extrémité haute 13a est filetée et qui est solidaire du porte-matières 1. Les clarinettes ou baïonnettes 13 de ce dernier étant disposées sur le plateau supérieur 12 du caisson 12a du porte-matières en correspondance géométrique des piles de bobines 2 garnissant le module 11, c'est la totalité de ses bobines qui est chargée sur le porte-matières 1 en une seule opération de transfert.More precisely, each stack of coils is connected by the axial channel which it presents on a clarinet with a perforated tube or a bayonet 13 with a star profile whose high end 13 a is threaded and which is integral with the material carrier 1. The clarinets or bayonets 13 of the latter being arranged on the upper plate 12 of the box 12 a of the material holder in geometrical correspondence of the stacks of coils 2 lining the module 11, it is all of its coils which is loaded on material carrier 1 in a single transfer operation.

A la suite de cette opération, chaque pile de bobines 2 repose sur le plateau 12 du caisson 12a du porte-matières 1 par une embase 10, laquelle assure simultanément l'étanchéité au contact dudit plateau, tandis que la solidité de chaque pile est renforcée par la mise en place, en partie haute de la pile, d'un dispositif de serrage à plaque 15 et écrou 14 propre à coopérer avec la partie filetée 13a d'une baïonnette 13 et avantageusement commun à une pluralité de piles.Following this operation, each stack of coils 2 rests on the plate 12 of the box 12 a of the material holder 1 by a base 10, which simultaneously ensures the sealing in contact with said plate, while the solidity of each pile is reinforced by the installation, in the upper part of the stack, of a clamping device with plate 15 and nut 14 suitable for cooperating with the threaded part 13 a of a bayonet 13 and advantageously common to a plurality of stacks.

Les dimensions et le contour en plan d'un porte-matières 1 sont de préférence comme montrés sur la figure 4, c'est-à-dire prévus pour permettre le chargement d'un certain nombre de modules 11, par exemple huit dans l'Exemple représenté, et qui sont référencés 11₁, 11₂, 11₃, etc...The dimensions and the plan outline of a material carrier 1 are preferably as shown in FIG. 4, that is to say provided to allow the loading of a certain number of modules 11, for example eight in the 'Example shown, and which are referenced 11₁, 11₂, 11₃, etc ...

Après que le porte-matières 1 ait été garni au poste B, il est transféré jusqu'au poste C où se trouve l'appareil de traitement 18. Comme montré sur la figure 5, celui-ci comprend, dans une première forme de réalisation, une cuve ou enceinte parallélépipédique 19, dont la section droite correspondant à celle d'une porte-matières et qui est munie de portes d'entrée et de sortie 20E et 20S, respectivement, réalisées ici en tant que portes coulissantes, verticales, d'autres exécutions étant bien entendu possibles, en particulier une réalisation à porte d'entrée et de sortie unique elle aussi, montée coulissante dans un plan vertical ou montée à pivotement en partie haute de l'enceinte comme montré sur la figure 10.After the material carrier 1 has been station B, it is transferred to station C where the processing apparatus 18 is located. As shown in FIG. 5, this comprises, in a first embodiment, a rectangular tank or enclosure 19, the cross section of which right corresponding to that of a material holder and which is provided with entry and exit doors 20E and 20S, respectively, produced here as sliding, vertical doors, other executions being of course possible, in particular a realization with a single entry and exit door too, slidingly mounted in a vertical plane or pivotally mounted in the upper part of the enclosure as shown in FIG. 10.

A sa partie supérieure la cuve ou enceinte 19 est fermée par un couvercle 21 traversé par un dispositif de serrage 30, dont le rôle sera précisé ci-après, tandis que sur le fond 18a de la cuve 19 sont posés des rails 17a avec lesquels coopèrent les roues 31a de quatre dispositifs d'essieux 31 fixés au caisson 12a du porte-matières et auxquels sont associés des dispositifs à ressorts 32 propres à permettre un mouvement vertical de bas en haut et/ou de haut en bas du porte-matières par rapport aux rails 17a.At its upper part, the tank or enclosure 19 is closed by a cover 21 crossed by a clamping device 30, the role of which will be specified below, while on the bottom 18 a of the tank 19 are rails 17 a with which cooperate with wheel 31 has four devices 31 fixed to the axle box 12 has the carrier material and with which are associated spring devices 32 suitable for allowing a vertical movement of the bottom to top and / or top to bottom of the door - materials with respect to the rails 17 a .

Dans le fond 18a de l'appareil 18 débouche une arrivée centrale 22 du fluide de traitement avec laquelle est propre à coopérer à étanchéité, comme il sera indiqué ci-après, un embout 3 solidaire du porte-matières et prévu pour l'introduction du fluide dans le caisson 12a du porte-matières 1, le retour du bain étant effectué par un embout 23 auquel est adjacent un échangeur de chaleur 25, avantageusement du type de ceux décrits dans FR-A-2 423 967, au nom de la Demanderesse.In the bottom 18 a of the device 18 opens a central inlet 22 of the treatment fluid with which is able to cooperate in sealing, as will be indicated below, a nozzle 3 secured to the material carrier and provided for the introduction fluid in the box 12 a of the material carrier 1, the return of the bath being effected by a nozzle 23 to which is adjacent a heat exchanger 25, advantageously of the type described in FR-A-2 423 967, in the name of the Applicant.

Ce fluide de traitement, introduit dans l'appareil 18 à partir d'une vanne 26 et dont la hauteur dans la cuve 19 est visualisée par un tube de niveau 33 est mis en circulation par une pompe 24, une vanne 27 étant prévue pour la vidange en fin de cycle de traitement, celui-ci ayant lieu à la pression atmosphérique ou sous pression statique d'air comprimé ou de gaz inerte, en correspondance de la condition d'une vanne 28 du couvercle 21 qui sert également de vanne de trop plein, l'expansion du bain ayant lieu dans le matelas d'air ou de gaz inerte situé au-dessus du niveau du bain lors d'un fonctionnement sous pression.This treatment fluid, introduced into the device 18 from a valve 26 and whose height in the tank 19 is displayed by a level tube 33 is circulated by a pump 24, a valve 27 being provided for the emptying at the end of the treatment cycle, this taking place at atmospheric pressure or under static pressure of compressed air or inert gas, in correspondence with the condition of a valve 28 of the cover 21 which also serves as an overflow valve, the expansion of the bath taking place in the mattress d air or inert gas located above bath level when operating under pressure.

Dans la variante illustrée sur les figures 6 à 9, le caisson 12a du porte-matières est remplacé par un plateau 34 sur lequel sont érigées, comme décrit ci-dessus, les clarinettes ou baïonnettes 13 et gui, comme dans la forme de réalisation précédente, est équipé de dispositifs à essieux 31 auxquels sont associés des dispositifs à ressorts 32. Dans cette variante, toutefois, le fluide de traitement, _ introduit par l'embout 22 au centre de la cuve 39 et dans le fond de celle-ci _, fait retour dans le circuit de circulation par plusieurs embouts 23 également placés dans le fond de la cuve ou enceinte 39. Comme bien visible sur les figures 8 et 9 ces embouts sont prévus au-dessous d'espaces 45 limités par la paroi latérale de la cuve 39, le fond 18a, une paroi verticale 46 interne à la cuve érigée à partir du fond 18a de celle-ci et une plaque 37 fixée sur la paroi latérale de la cuve et la paroi 46; dans la plaque 37, percée d'orifices 40, sont montés des joints d'étanchéité 38 avec lesquels est propre à coopérer la face inférieure du plateau 34 du porte-matières 1, tandis que des joints analogues 36 sont prévus sur la face inférieure de règles 35 fixées sur la porte unique (dans le cas d'un appareil à une seule ouverture d'entrée et de sortie) ou sur les portes 20E et 20S de l'appareil des figures 6 et 7. Dans le cas d'un appareil à porte unique, l'invention prévoit également de munir la cuve ou enceinte d'une cloison verticale, plane au voisinage de la partie arrière fermée de celle-ci, ladite paroi permettant une liaison par le bas entre la partie avant de traitement et la partie arrière d'expansion du bain, comme décrit, par exemple, dans US-A-4 581 906.In the variant illustrated in Figures 6 to 9, the box 12 a of the material holder is replaced by a plate 34 on which are erected, as described above, the clarinets or bayonets 13 and mistletoe, as in the embodiment previous, is equipped with axle devices 31 with which are associated spring devices 32. In this variant, however, the treatment fluid, _ introduced by the nozzle 22 in the center of the tank 39 and in the bottom thereof _, returns to the circulation circuit by several end pieces 23 also placed in the bottom of the tank or enclosure 39. As clearly visible in FIGS. 8 and 9 these end pieces are provided below spaces 45 limited by the side wall of the tank 39, the bottom 18 a , a vertical wall 46 internal to the tank erected from the bottom 18 a of the latter and a plate 37 fixed to the side wall of the tank and the wall 46; in the plate 37, pierced with orifices 40, are mounted seals 38 with which is adapted to cooperate the underside of the plate 34 of the material carrier 1, while similar seals 36 are provided on the underside of rules 35 fixed on the single door (in the case of a device with a single opening for entry and exit) or on doors 20E and 20S of the device of FIGS. 6 and 7. In the case of a device with a single door, the invention also provides for providing the tank or enclosure with a vertical, flat partition in the vicinity of the closed rear part thereof, said wall allowing a connection from below between the front treatment part and the rear part of bath expansion, as described, for example, in US-A-4,581,906.

Le fonctionnement de l'une et de l'autre des formes de réalisation décrites résulte immédiatement de ce qui précède.The operation of either of the embodiments described results immediately from the above.

Dans la réalisation illustrée sur la figure 5, le porte-matières garni au poste B des bobines 2 est introduit dans l'appareil de traitement 18 à axe horizontal après que la porte unique ou la porte d'entrée 20E ait été soulevée (position montrée en tirets sur le dessin) et qu'aient été amenés dans la position, également montrée en tirets, des rails de liaison pivotants 29E assurant la continuité du chemin de roulement entre les rails 17 posés entre le poste B et l'appareil de traitement 18 et les rails 17a dudit appareil de traitement.In the embodiment illustrated in FIG. 5, the material carrier stocked at station B with coils 2 is introduced into the processing device 18 with a horizontal axis after the single door or the entry door 20E has been lifted (position shown in dashes in the drawing) and that have been brought into position, also shown in dashes, pivoting connecting rails 29E ensuring the continuity of the raceway between the rails 17 placed between the station B and the processing device 18 and the rails 17 a of said processing apparatus.

En variante, le porte-matières garni des bobines est introduit dans l'appareil de traitement 18 par un dispositif de transpalette ou par des moyens de guidage à glissement, ou encore par des organes de transport du type filoguidé ou analogue.As a variant, the material carrier lined with the reels is introduced into the processing device 18 by a pallet truck device or by sliding guide means, or also by transport members of the wire-guided type or the like.

Après positionnement précis du porte-matières 1 à l'intérieur de la cuve 19, les moyens de serrage 30 sont actionnés pour coopérer avec une colonne centrale 30a du porte-matières et réaliser le contact étanche de l'embout 22 d'introduction du fluide de traitement dans l'appareil et de l'embout 3 par lequel ledit fluide pénètre dans le caisson 12a du porte-matières 1. Au cours de l'actionnement des moyens 30 les dispositifs à ressorts 32 des dispositifs d'essieux 31 sont comprimés par abaissement du caisson 12a du porte-matières, favorisant l'étanchéité du circuit de circulation du fluide de traitement.After precise positioning of the material carrier 1 inside the tank 19, the clamping means 30 are actuated to engage with a center column 30a of the material carrier and achieve tight contact of the nozzle 22 for introducing the treatment fluid in the device and the nozzle 3 through which said fluid enters the box 12 a of the material carrier 1. During the actuation of the means 30 the spring devices 32 of the axle devices 31 are compressed by lowering the box 12 a of the material holder, promoting the sealing of the circulation circuit of the treatment fluid.

Celui-ci est introduit dans l'appareil 18 par la vanne 26, après fermeture de la porte d'entrée 20E et le niveau du bain de fluide est ajusté entre les positions No et NR du tube de niveau 33, en fonction des desiderata de la pratique. Le niveau est, par exemple, ajusté à la valeur Nl pour un traitement du type "non-immergé", c'est-à-dire un traitement selon lequel la bobine 2 des piles de bobines adjacente au plateau 12 est partiellement immergée ou n'est pas immergée du tout, le niveau libre du bain, dans la condition non-opératoire de la pompe de mise en circulation, étant au-dessous du niveau des bobines les plus proches du fond de l'enceinte de l'appareil de traitement. Le bain de traitement est ensuite mis en circulation au moyen de la pompe 24 pour provoquer une circulation dudit bain de l'intérieur vers l'extérieur des bobines, ou de l'extérieur vers l'intérieur ou, encore, dans les deux sens, en alternance.This is introduced into the device 18 by the valve 26, after closing the entry door 20E and the level of the fluid bath is adjusted between the positions N o and N R of the level tube 33, depending on the practice wishes. The level is, for example, adjusted to the value N l for a treatment of the "non-submerged" type, that is to say a treatment according to which the coil 2 of the coil stacks adjacent to the plate 12 is partially immersed or is not immersed at all, the free level of the bath, in the non-operating condition of the circulation pump, being below the level of the coils closest to the bottom of the enclosure of the processing device. The treatment bath is then circulated by means of the pump 24 to cause said bath to circulate from the inside to the outside of the coils, or from the outside to the inside or, again, in both directions, alternately.

Par un choix approprié de la vitesse du moteur d'entrainement de la pompe, par exemple une pompe hélicocentrifuge réversible, le débit de cette dernière peut être réglé pour une parfaite maîtrise de la circulation du bain de traitement au travers des fils, mèches et rubans constitutifs des bobines avec pour résultat une meilleure qualité de la matière textile traitée en raison de l'absence de variation brutale de débit au travers des enroulements de matière.By an appropriate choice of the speed of the pump drive motor, for example a reversible helico-centrifugal pump, the flow rate of the latter can be adjusted for perfect control of the circulation of the treatment bath through wires, wicks and ribbons constituting the coils resulting in a better quality of the textile material treated due to the absence of abrupt variation of flow through the material windings.

Par ailleurs, cette disposition permet d'effectuer le traitement à faible volume de bain, de l'ordre de 1/4, c'est-à-dire avec de substantielles économies d'eau, de calories apportées par l'échangeur de chaleur 25, de produits chimiques de traitement et/ou des rejets.Furthermore, this arrangement makes it possible to carry out the treatment at low bath volume, of the order of 1/4, that is to say with substantial savings in water and calories provided by the heat exchanger. 25, treatment chemicals and / or releases.

A la fin du traitement les moyens 30 sont rendus inopératoires, les dispositifs à ressorts 32 provoquent un léger mouvement vers le haut du caisson 12a, libèrent les dispositifs d'essieux 31 et interrompent de ce fait la continuité du circuit de circulation du bain de fluide.At the end of the treatment, the means 30 are rendered inoperative, the spring devices 32 cause a slight upward movement of the box 12 a , release the axle devices 31 and thereby interrupt the continuity of the circulation circuit of the bath of fluid.

La porte unique de l'appareil ou la porte de sortie 20S de l'appareil 18 à deux portes est ouverte par amenée dans sa condition montrée en tirets sur la figure et, après que des rails de liaison 29S aient été amenés par pivotement dans la condition également montrée en tirets sur ladite figure, ou que des moyens analogues de guidage du ou des porte-matières aient été mis en place, ledit porte-matières 1 est extrait de l'appareil 18 et est guidé par circulation sur les rails 17 jusqu'au poste D où il est déchargé.The single door of the appliance or the exit door 20S of the appliance 18 with two doors is opened by being brought in its condition shown in dashes in the figure and, after connecting rails 29S have been brought by pivoting in the condition also shown in dashes in said figure, or that similar means for guiding the or material carriers have been put in place, said material carrier 1 is extracted from the device 18 and is guided by circulation on the rails 17 to the station D where it is unloaded.

La durée de chargement et de déchargement d'un porte-matières d'une installation selon l'invention est considérablement réduite par rapport à celle des installations connues, le temps de chargement et/ou de déchargement de huit modules comportant chacun cent vingt huit bobines (32 piles de 4 bobines) étant très inférieur au temps de manutention une à une de mille vingt quatre bobines (8×32×4).The loading and unloading time of a material carrier of an installation according to the invention is considerably reduced compared to that of known installations, the loading and / or unloading time of eight modules each comprising one hundred and twenty eight coils (32 stacks of 4 reels) being much less than the handling time one to one of one thousand twenty four reels (8 × 32 × 4).

Dans la réalisation illustrée sur les figures 6 à 9, l'introduction du porte-matières 1 dans l'appareil de traitement 18 est analogue à celle décrite ci-dessus sous réserve que lorsque les moyens 30 sont rendus opératoires pour coopérer avec la colonne centrale 30a du porte-matières, le mouvement vers le bas du plateau 34, comme montré par la flèche F sur la figure 8, provoque l'application dudit plateau sur les moyens de joint 38 tandis que la fermeture de la ou des portes 20 applique à étanchéité les joints 36 sur la face supérieure dudit plateau. Après remplissage et ajustement du niveau du bain, comme décrit ci-dessus, la pompe 24 de mise en circulation du bain est rendue opératoire pour faire circuler celui-ci de l'intérieur vers l'extérieur des bobines, ou de l'extérieur vers l'intérieur, ou en alternance dans un sens puis dans l'autre. Dans le premier cas, le bain issu de la pompe 24 par l'embout central 22 pénètre dans la cuve 39 sous le plateau 34 du porte-matières 1, traverse les bobines 2 par l'orifice central des piles et fait retour à la pompe au travers des orifices 40, des espaces 45, et des embouts 23.In the embodiment illustrated in FIGS. 6 to 9, the introduction of the material holder 1 into the treatment apparatus 18 is similar to that described above, provided that when the means 30 are made operational to cooperate with the central column 30 a of the material carrier, the downward movement of the plate 34, as shown by the arrow F in FIG. 8, causes the application of said plate on the seal means 38 while the closing of the door or doors 20 applies to seal the seals 36 on the upper face of said plate. After filling and adjusting the level of the bath, as described above, the pump 24 for circulating the bath is made operative to circulate the latter from the inside to the outside of the coils, or from the outside to inside, or alternately in one direction then in the other. In the first case, the bath from the pump 24 through the central nozzle 22 enters the tank 39 under the plate 34 of the material carrier 1, crosses the coils 2 through the central orifice of the batteries and returns to the pump through orifices 40, spaces 45, and end pieces 23.

C'est un sens de circulation inverse qui est mis en oeuvre pour un traitement de matières textiles par circulation du bain de traitement au travers des enroulements de l'extérieur vers l'intérieur.It is a reverse flow direction which is used for a treatment of textile materials by circulation of the treatment bath through the windings from the outside to the inside.

Dans cette forme de réalisation, également, le traitement peut être effectué à pression atmosphérique ou sous pression statique d'air comprimé ou de gaz inerte et, ici aussi, avec un rapport de bain court ou très court, de l'ordre de 1/4, notablement inférieur à celui des installations connues de l'Art antérieur (valeurs de l'ordre de 1/10 à 1/6).In this embodiment, also, the treatment can be carried out at atmospheric pressure or under static pressure of compressed air or inert gas and, here too, with a short or very short bath ratio, of the order of 1 / 4, significantly lower than that of installations known from the prior art (values of the order of 1/10 to 1/6).

L'invention prévoit aussi, dans l'une et/ou l'autre des réalisations décrites ci-dessus, de robotiser le fonctionnement de l'installation à la fois en ce qui concerne le chargement et/ou le déchargement des modules 11 et en ce qui concerne la mise en place et/ou l'extraction du porte-matières 1 dans l'appareil de traitement 18.The invention also provides, in one and / or the other of the embodiments described above, to robotize the operation of the installation both as regards the loading and / or unloading of the modules 11 and in as regards the positioning and / or extraction of the material carrier 1 in the processing apparatus 18.

Les déplacements dans un plan horizontal du porte-matières à son entrée et à sa sortie de l'appareil de traitement sur des rails ou sur des moyens de guidage analogues par exemple des moyens de filoguidage, la structure de l'appareil de traitement à une ou à des portes coulissantes de même que le système de serrage central des porte-matières rendent une telle robotisation relativement simple.The displacements in a horizontal plane of the material carrier at its entry and at its exit from the treatment apparatus on rails or on similar guiding means for example wire guidance means, the structure of the treatment apparatus at a or to sliding doors as well as the central clamping system of the material carriers make such robotization relatively simple.

Bien que l'invention ait été décrite en référence à une cuve d'appareil de traitement de forme générale parallélépipédique, il est clair que l'invention n'est pas limitée à cette forme de réalisation.Although the invention has been described with reference to a treatment vessel of generally parallelepiped shape, it is clear that the invention is not limited to this embodiment.

L'invention peut, en particulier, être mise en oeuvre dans une installation comportant un appareil de traitement à enceinte externe horizontale cylindrique garnie intérieurement de moyens de partition verticale définis par des caissons étanches ayant chacun une forme parallélépipédique.The invention can, in particular, be implemented in an installation comprising a treatment device with a cylindrical horizontal external enclosure internally lined with vertical partition means defined by watertight boxes each having a parallelepiped shape.

L'invention peut, ainsi, être mise en oeuvre dans une installation comprenant un appareil de traitement à enceinte externe à axe horizontal munie en son intérieur de parois verticales ménagées par des caissons étanches définissant un ou plusieurs volumes parallélépipédiques de réception des porte-matières. Cette réalisation, montrée sur les figures 10 et 11, est prévue pour recevoir deux porte-matières 1a, 1b chacun propre à être muni de quatre modules de dix piles chacun. La longueur de l'enceinte est d'environ 5 m. et le diamètre d'environ 1,8 m., avec les caissons 50 et 51 définissant par leurs parois verticales 52 et 53 un volume sensiblement parallélépipédique pour les porte-matières. L'appareil comprend l'échangeur de chaleur 25, une pompe 24, avantageusement du type hélicocentrifuge réversible et les moyens de guidage 54 et 55 de chargement et de déchargement du ou des porte-matières dans l'enceinte, lesdits moyens étant formés par des rails, des glissières, des pistes de circulation ou des appareils à filoguidage. Dans cette réalisation, deux moyens de serrage 30a et 30b sont prévus dans le couvercle 21. Le fluide de traitement traverse les pièces traitées par un circuit défini par des ouvertures dans le fond 18a de l'enceinte externe, ledit circuit comprenant l'embout 22 relié à la pompe 24 et les embouts 23 débouchant également dans le fond 18a. Les moyens d'étanchéité pour établir et assurer la continuité du circuit de fluide de traitement sont montrés en 60.The invention can thus be implemented in an installation comprising a treatment device with an external enclosure with a horizontal axis provided inside with vertical walls formed by watertight boxes defining one or more parallelepiped volumes of reception of material carriers. This embodiment, shown in Figures 10 and 11, is provided to receive two carrier material 1 a, 1 b each adapted to be provided with four modules each of ten batteries. The length of the enclosure is approximately 5 m. and the diameter of about 1.8 m., with the boxes 50 and 51 defining by their vertical walls 52 and 53 a substantially parallelepiped volume for the material carriers. The apparatus comprises the heat exchanger 25, a pump 24, advantageously of the reversible helical-centrifugal type and the guide means 54 and 55 for loading and unloading the material carrier (s) in the enclosure, said means being formed by rails, slides, traffic lanes or wire guidance devices. In this embodiment, two clamping means 30 a and 30 b are provided in the cover 21. The treatment fluid passes through the parts treated by a circuit defined by openings in the bottom 18 a of the external enclosure, said circuit comprising l 'end piece 22 connected to the pump 24 and the end pieces 23 also opening into the bottom 18a. The sealing means for establishing and ensuring the continuity of the treatment fluid circuit are shown at 60.

Dans cette réalisation, de façon analogue à ce qui est monté sur la figure 5, le niveau de fluide peut être ajusté à No pour un traitement du type "non-immergé", c'est-à-dire avec aucune des bobines au contact du bain dans la condition non-opératoire de la pompe ou à tout niveau compris entre No et N₄ (niveau montré en traits pointillés sur la figure 11) et qui est celui pour lequel toutes les bobines sont immergées dans le bain même dans la condition non-opératoire de la pompe 24.In this embodiment, analogously to what is shown in FIG. 5, the fluid level can be adjusted to N o for a treatment of the "non-submerged" type, that is to say with none of the coils at contact of the bath in the non-operating condition of the pump or at any level between N o and N₄ (level shown in dotted lines in Figure 11) and which is the one for which all the coils are immersed in the bath even in the pump non-operating condition 24.

On se réfère maintenant aux figures 12 à 16 qui montrent un appareil selon l'invention pour le traitement de pièces conformées suivant des écheveaux de fils, fibres ou matériaux textiles analogues. Le dispositif porte-matières comprend une cuve 110 à fond 112 et enveloppe latérale 111 dans laquelle est ménagée une ouverture 113 qui peut être fermée ou dégagée par une porte 114, réalisée ici en tant que porte coulissant verticalement. Sur le fond 112 est abouché un embout 115 de liaison et de mise en communication du volume V parallélépipédique intérieur au porte-matières avec le circuit de fluide de traitement liquide ou gazeux de la machine par exemple par l'embout 22 relié à la pompe 24. A l'intérieur du porte-matières est prévu un premier couple d'organes disposés horizontalement dans la condition d'utilisation du dispositif et dont un des organes est montré en 116, et un second couple d'organes sensiblement parallèles aux premiers et dont l'un est montré en 117, au voisinage du fond 112, alors que le premier couple d'organes 116 est prévu au voisinage de l'extrémité supérieure de l'enveloppe 111.Reference is now made to FIGS. 12 to 16 which show an apparatus according to the invention for the treatment of shaped parts according to skeins of threads, fibers or similar textile materials. The material-holding device comprises a tank 110 with bottom 112 and lateral envelope 111 in which is formed an opening 113 which can be closed or released by a door 114, produced here as a vertically sliding door. On the bottom 112 is connected a nozzle 115 for connecting and communicating the volume V parallelepiped inside the material carrier with the liquid or gaseous treatment fluid circuit of the machine for example by the nozzle 22 connected to the pump 24 Inside the material carrier is provided a first pair of members arranged horizontally in the condition of use of the device and one of the members of which is shown at 116, and a second pair of members substantially parallel to the first and of which one is shown at 117, in the vicinity of the bottom 112, while the first pair of members 116 is provided in the vicinity of the upper end of the envelope 111.

L'écartement respectif des couples d'organes 116, 117 est réglable, par des moyens non représentés, pour adapter ledit écartement au périmètre des écheveaux E de fils, fibres, filés ou filaments à traiter. Ces écheveaux E sont enfilés sur des barreaux B et C, dont les premiers supportent les écheveaux E et dont les seconds sont prévus pour les faire pendre de manière telle qu'ils ne s'emmèlent pas les uns dans les autres.The respective spacing of the pairs of members 116, 117 is adjustable, by means not shown, to adapt said spacing to the perimeter of the skeins E of threads, fibers, yarns or filaments to be treated. These skeins E are strung on bars B and C, the first of which support the skeins E and the second of which are designed to make them hang so that they do not become entangled in each other.

Dans une forme de réalisation comportant uniquement le couple d'organes 116, les barreaux B sont placés de manière à chevaucher lesdits organes lorsque la porte 114 est ouverte et que les écheveaux sont introduits dans le porte-matières comme montré par la direction de la flèche f sur la figure 12.In an embodiment comprising only the pair of members 116, the bars B are placed so as to overlap said members when the door 114 is open and the skeins are introduced into the material holder as shown by the direction of the arrow f in Figure 12.

Dans une autre forme de réalisation, comportant deux couples d'organes 116 et 117, les barreaux B sont placés comme dans la forme de réalisation décrite immédiatement ci-dessus, mais les barreaux C sont positionnés sous les organes 117, ici aussi au chargement du porte-matières dans la condition d'ouverture de la porte 114.In another embodiment, comprising two pairs of members 116 and 117, the bars B are placed as in the embodiment described immediately above, but the bars C are positioned under the members 117, here also when loading the material carrier in the condition of opening the door 114.

Les organes 116, 117 peuvent être constitués par des tiges ou rails.The members 116, 117 may be constituted by rods or rails.

En variante, les organes 116 de support des barreaux B sont des rails et les organes 117 sont des glissières dans lesquelles sont introduits les barreaux ou analogues C et cela de manière à permettre un léger retrait des écheveaux E tout en interdisant qu'ils s'emmèlent les uns dans les autres.As a variant, the members 116 for supporting the bars B are rails and the members 117 are slides in which the bars or the like C are introduced and this so as to allow a slight withdrawal of the skeins E while preventing them from s' entwine each other.

Dans encore une autre variante, à la fois les organes 116 et les organes 117 sont constitués par des glissières parallèles.In yet another variant, both the members 116 and the members 117 are constituted by parallel slides.

Dans la forme de réalisation montrée sur la figure 13 les barreaux B de support des écheveaux reposent en alternance sur l'un et l'autre de deux premiers couples de tiges ou rails 116a et 116b, décalés en hauteur par rapport au fond 112, permettant ainsi une plus grande densité de chargement du porte-matières et une meilleure homogénéité de traitement, les matières textiles n'étant en aucun point des écheveaux serrées entre deux barreau adjacents.In the embodiment shown in FIG. 13, the bars B for supporting the hanks rest alternately on one and the other of two first pairs of rods or rails 116 a and 116 b , offset in height relative to the bottom 112 , thus allowing a greater loading density of the material carrier and a better homogeneity of treatment, the textile materials being at no point skeins clamped between two adjacent bars.

Lorsque des rails 117a et 117b sont prévus, ceux-ci sont également décalés en hauteur, en correspondance des rails 116a et 116b.When rails 117 a and 117 b are provided, these are also offset in height, in correspondence of the rails 116 a and 116 b.

Dans la réalisation montrée sur la figure 14, l'invention prévoit que les organes disposés près du fond 112 et avec lesquels coopèrent les barreaux C soient des glissières 117c et 117d décalées en hauteur en correspondance des rails 116a et 116b.In the embodiment shown in FIG. 14, the invention provides that the members arranged near the bottom 112 and with which the bars C cooperate are slides 117 c and 117 d offset in height in correspondence with the rails 116 a and 116 b .

Dans une autre variante, non représentée, aussi bien les organes 116 que les organes 117 sont des glissières décalées en hauteur par rapport au fond 112.In another variant, not shown, both the members 116 and the members 117 are slides offset in height relative to the bottom 112.

Le porte-matières selon l'invention est également muni de moyens destinés à assurer une bonne répartition du fluide liquide ou gazeux de traitement des matières à traiter et lesdits moyens, par exemple sous forme de grilles, sont disposés parallèlement au fond 112, l'une 120 adjacente audit fond et l'autre 121 en partie haute de l'enveloppe.The material carrier according to the invention is also provided with means intended to ensure a good distribution of the liquid or gaseous fluid for treating the materials to be treated and said means, for example in the form of grids, are arranged parallel to the bottom 112, the a 120 adjacent to said audit bottom and the other 121 in the upper part of the envelope.

La face externe de l'enveloppe latérale 111 peut être munie, conformément à l'invention, de corps morts lesquels, en réduisant l'espace entre la cuve 110 et l'intérieur de la machine de traitement au mouillé permettent de diminuer le volume de bain mis en oeuvre pour le traitement de la matière constituant les écheveaux E et, ainsi, de travailler à courts ou très courts rapports de bains.The external face of the lateral envelope 111 can be provided, in accordance with the invention, with dead bodies which, by reducing the space between the tank 110 and the interior of the wet treatment machine, make it possible to reduce the volume of bath used for the treatment of the material constituting the skeins E and, thus, to work with short or very short bath reports.

L'installation selon l'invention facilite de façon importante les opérations de manutention des écheveaux en permettant l'introduction en succession desdits écheveaux dans une succession de machines sans qu'il soit besoin de charger et décharger les écheveaux dans des bacs de stockage intermédiaires, comme requis jusqu'alors dans les installations utilisant des porte-matières connus. Ainsi, si la longueur utile des barreaux B correspond à celle des bras d'une machine de mercerisage, chacun des bras de ladite machine est déchargé sur un barreau B et, après que lesdits écheveaux aient été munis, le cas échéant, de barreaux C ils sont mis en place dans le porte-matières en vue du traitement ultérieur de lavage, de blanchiment, de teinture ou autre traitement liquide.The installation according to the invention considerably facilitates the hank handling operations by allowing the said hanks to be introduced in succession into a succession of machines without the need to load and unload the hanks in intermediate storage tanks, as previously required in installations using known material carriers. Thus, if the useful length of the bars B corresponds to that of the arms of a mercerizing machine, each of the arms of said machine is unloaded onto a bar B and, after said skeins have been provided, where appropriate, with bars C they are placed in the material carrier for the subsequent washing, bleaching, dyeing or other liquid treatment.

Celui-ci peut être effectué dans une machine telle que décrite en référence aux figures 10 et 11, et comme montré sur les figures 17 et 18 où deux porte-matières 110a et 110b sont placés côte à côte dans la machine. Le traitement peut aussi être effectué dans une machine comme montrée sur la figure 16 où un bain de traitement est mis en circulation dans un autoclave A à faux-fond 123 percé d'une ouverture 130 prévue à l'extrémité supérieure d'une tuyauterie 131, tandis qu'une ouverture 132 est propre à être raccordée à une tuyauterie 133, cette dernière et la tuyauterie 131 étant reliées à une pompe, non représentée, située sous l'autoclave A pour assurer la circulation du bain de traitement. Le bain peut circuler dans la direction allant de l'ouverture 132 vers la tuyauterie 131, comme montré par les flèches, ou dans la direction opposée. Le faux-fond 123 présente une ouverture 135 ménagée sensiblement dans l'axe de l'ouverture 132 et conçue pour recevoir un échangeur de chaleur, non représenté, des logements 136 à la périphérie du faux-fond étant prévus pour recevoir des canalisations intérieures 137 qui en sont rendues solidaires.This can be performed in a machine as described with reference to Figures 10 and 11, and as shown in Figures 17 and 18 where two carrier materials 110 a and 110 b are placed side by side in the machine. The treatment can also be carried out in a machine as shown in FIG. 16 where a treatment bath is put into circulation in an autoclave A with false bottom 123 pierced with an opening 130 provided at the upper end of a pipe 131 , while an opening 132 is suitable for being connected to a pipe 133, the latter and the pipe 131 being connected to a pump, not shown, located under the autoclave A to ensure the circulation of the treatment bath. The bath can flow in the direction from the opening 132 towards the piping 131, as shown by the arrows, or in the opposite direction. The false bottom 123 has an opening 135 formed substantially in the axis of the opening 132 and designed to receive a heat exchanger, not shown, housings 136 at the periphery of the false bottom being provided to receive internal pipes 137 which are made integral therewith.

La circulation du fluide de traitement a lieu au travers de l'embout 115 du porte-matières assurant la mise en communication du volume V parallélépipédique intérieur au porte-matières avec le circuit comprenant les tuyauteries 131, 133 et la pompe, non représentée, tandis que les grilles ou analogues 120 et 121 assurent une bonne répartition du bain sur les écheveaux de matières à traiter. Après traitement de lavage, de blanchiment, de teinture ou autre traitement liquide dans la machine illustrée sur les figures 10 et 11, ou dans une machine analogue, le porte-matières est extrait de l'autoclave A et est introduit dans un appareil de séchage du type de celui décrit dans la Demande de Brevet Européen n° 86400718 du 3 avril 1986 au nom de la Demanderesse. Un tel appareil de séchage S comporte une cuve 140 fermée par un couvercle 141. Celui-ci est muni de moyens 142 et d'un dispositif 143 propre à coopérer avec un dispositif 143₁ de triangle horizontal reposant sur la face supérieure du porte-matières pour établir et assurer la continuité du circuit de fluide de traitement en appliquant à force, par serrage, le fond 112 du porte-matières contre des moyens de joint 145 prévus à l'extrémité d'une boîte de distribution 146 dans laquelle aboutissent des canalisations 147 et 148 pour l'entrée et/ou la sortie de fluide dans le porte-matières, la sortie et/ou l'entrée de fluide dans la cuve 140, respectivement, étant réalisée à l'aide de canalisations 150 et 151 qui débouchent dans ladite cuve.The circulation of the treatment fluid takes place through the tip 115 of the material carrier ensuring the communication of the volume V parallelepiped inside the material carrier with the circuit comprising the pipes 131, 133 and the pump, not shown, while that the grids or the like 120 and 121 ensure good distribution of the bath on the skeins of materials to be treated. After washing, bleaching, dyeing or other liquid treatment in the machine illustrated in FIGS. 10 and 11, or in a similar machine, the material carrier is extracted from autoclave A and is introduced into a drying apparatus. of the type described in European Patent Application No. 86400718 of April 3, 1986 in the name of the Applicant. Such a drying apparatus S comprises a tank 140 closed by a cover 141. The latter is provided with means 142 and a device 143 suitable for cooperating with a device 143₁ of horizontal triangle resting on the upper face of the material holder for establish and ensure the continuity of the treatment fluid circuit by forcibly applying, by tightening, the bottom 112 of the material carrier against seal means 145 provided at the end of a distribution box 146 in which pipes 147 terminate and 148 for the inlet and / or outlet of fluid into the material carrier, the outlet and / or inlet of fluid into the tank 140, respectively, being carried out using pipes 150 and 151 which open into said tank.

Dans un mode opératoire, l'air traité ou non traité est introduit dans la cuve 140 par la canalisation 150, pénètre dans le porte-matières au travers du répartiteur de fluide 121, comme montré par les flèches g, quitte le porte-matières au travers du répartiteur de fluide 120 et est évacué par les moyens de liaison 115 du porte-matières avec le reste de l'appareil de séchage.In one operating mode, the treated or untreated air is introduced into the tank 140 through the pipe 150, enters the material carrier through the fluid distributor 121, as shown by the arrows g , leaves the material carrier through the fluid distributor 120 and is discharged by the connecting means 115 of the material carrier with the rest of the drying apparatus.

Dans un autre mode opératoire, c'est une circulation en sens inverse de l'air traité ou non traité, qui est utilisée.In another operating mode, it is a circulation in the opposite direction of the treated or untreated air, which is used.
