Definitions
- the present invention relates to a machine for the continuous treatment of textile or other parts.
- This machine is aimed more particularly, although not exclusively, at washing and rinsing textile parts.
- a machine for this type of treatment comprising a drum provided with a perforated cylindrical wall and rotatably mounted around a horizontal axis inside a tank, and in which the space in annular section formed between the drum and the bottom of the tank, which is intended to receive and transmit to the interior of the drum, through the perforations of its cylindrical wall, the treatment liquids, is divided by internal flanges in tight contact, by seals, with the cylindrical wall of the drum, in as many compartments as there are treatment liquids, while there are provided, inside the drum, means for driving the textile pieces, parallel to the axis of the drum, from its inlet end to its outlet end, other means being provided outside the drum for its rotational drive during the treatment.
- the means for driving the textile pieces inside the drum are constituted by a helical ferrule, integral with the internal face of the drum and extending from one to the other of its ends.
- this helical ferrule pushes forward not only the parts being treated but also the various treatment liquids which, at the outlet of the drum, are intimately mixed, which, obviously, harms the quality of treatment.
- the textile pieces especially if they are likely to be impregnated with the treatment liquids, also participate in this transfer and this mixing of the liquids, because they are never extracted from the baths formed by these liquids in the bottom of the drum.
- the drum is driven by hoops which, fixed at its ends projecting from the tank, form raceways bearing on support rollers, at least one of which is powered.
- the object of the present invention is to remedy the drawbacks of sequential tunnels and modular tunnels by providing a machine which, separating the baths and, draining the textile pieces between the different phases of the treatment, is inexpensive to carry out and leads to costs of '' reduced maintenance.
- This machine is of the type comprising a drum provided with a perforated cylindrical wall and rotatably mounted around a horizontal axis inside a tank, and in which the annular space formed between the drum and the bottom of the tank , to receive and transmit inside the drum, the treatment liquids, is divided by internal flanges in tight contact, by seals, with the cylindrical wall of the drum, in as many compartments as there are treatment, while there are provided, inside the drum, means for driving the textile pieces, parallel to the axis of the drum, from its inlet end to its outlet end, other means being provided outside the drum for its rotational drive during treatment.
- the treated parts are extracted from the bath by the shovel associated with this compartment and are drained on this shovel before being deposited in the next compartment.
- the tank has two dry compartments, that is to say isolated from the bath, housing the two sets of support rollers of the drums and their rotary drive means, each hoop of the drum being fixed to the latter in correspondence with one of these dry compartments.
- each of the ends of each of the tank elements has a housing for fixing the heel of a lip seal, the lip of which faces towards the inside of the annular compartment formed between the tank element and the drum, is pressed elastically against the external face of a solid hoop, fixed on the periphery of the drum.
- this machine is composed of a cylindrical drum 2, with a perforated wall, rotatably mounted around a horizontal axis inside a tank, generally designated by 3, and itself carried by a chassis 4.
- Space annular formed between the drum 2 and the bottom of the tank 3 is divided into several compartments by internal radial flanges 6, in sealed contact with the wall of the drum 2. In the embodiment shown, these compartments are the number of ten and are referenced C1 to C10.
- the perforated drum 2 is divided into as many compartments as those of the tank by internal annular flanges 7, in the form of a crown opposing the transfer of the treatment liquids from one compartment to the other.
- Each collar 7 is arranged in the same diametrical plane as the collar 6 which corresponds to it.
- Each compartment includes means for transferring textile pieces during processing to the next compartment, means which consist of a perforated frustoconical shovel 8.
- the semi-circular base 8a of larger diameter, embraces at least half -circumference of the outlet orifice 9 of the compartment, while its end 8b, of smaller diameter, extends to the inlet orifice of this compartment.
- FIG. 3 shows that the front longitudinal end 8b of the shovel 8, which is then seen in its direction of rotation, comes into contact with the internal face of the cylindrical wall of the drum 2, of which it contributes to stiffening.
- Each compartment of the drum 2 comprises, on the internal face of this drum, ribs 12 for driving the textile parts. These ribs are arranged parallel to the generatrices of the drum and are angularly offset from one another. Figure 3 highlights that the two ribs 12 disposed on either side of the upstream end 8b of the perforated shovel 8 have a lower height than the other ribs.
- the ribs 12 of each of the compartments of the drum are aligned with those of the other compartments and are rigidly fixed by their ends to the flanges 7 of the drum, so as to form, by bracing, stiffening longitudinal members the drum and improving its torsional stiffness, helped in this by the shovels 8.
- the tank 3 comprises two dry compartments S1 and S2 which are isolated from the bath and which constitute housings for means for driving and supporting the drum.
- these dry compartments are produced in compartments C3 and C8 of the tank, but they can of course be located in any other compartment, depending on the stresses exerted on the drum by the levels of the liquid of treatment in the various compartments, levels varying according to the compartments.
- the tank 3 is therefore divided into a central element 3b and into two lateral elements, respectively 3a and 3c.
- each end of each of the elements 3a-3b and 3c of the tank is provided with a housing 15 for the heel 16a of a lip seal 16 whose lip 16b, facing towards inside the element of the tank, comes into sealing contact with a hoop fixed against the external wall of the drum 2.
- the latter therefore comprises two hoops 17, delimiting the dry compartments and two end hoops 18, fixed to its extremities.
- FIG. 4 shows that the seal between the various compartments C1 to C10 of the tank, within each of its elements 3a-3b-3c, is ensured by means of the internal flanges 6, projecting radially in the compartment and substantially in the extension of the corresponding flange 7 of the drum, and by seals, generally designated by 20.
- the heel 20a of each seal is trapped by annular rings 22 fixed on ribs 23 projecting from the periphery of the drum.
- the two lips 20b of the seal trap, by elastic and leaktight contact, the external edges of the collar 6.
- the different compartments C1 to C10 are completely independent of each other, which makes it possible, for each compartment, to perfectly control the composition of the bath, its level and its temperature.
- At least one compartment of the tank is provided in the upper part thereof with an inspection door 31 (FIG. 1) allowing, with another inspection door 32 (FIG. 2) formed on the corresponding compartment of the drum, to access the interior of the drum compartment to clear the textile products forming a jam in the chute or in the compartment, avoiding having to cross all the upstream or downstream compartments, as is the case in tunnels current.
- This door or these inspection doors are arranged on the compartments subject to jams.
- the compartments C1-C2 are assigned to the prewash, represented by the brace P in FIG. 2, while those C3 to C6 are assigned to the washing, as represented by the brace L to the same figure and that those C7 to C10 are assigned to rinsing, as represented by the brace R. It is obvious that this distribution is not imperative and can be adapted according to the needs of the treatment. The same is true for the number of compartments which is not limited to ten and which, for example, can vary from 8 to 16, depending on requirements.
- the rotation of the tank, carried out in each of the dry compartments, is ensured by a pair of spaced rollers 25, mounted free in rotation in consoles 26 of the chassis 4 and connected by movement transmissions, of the V-belt type, notched or not, to geared motors 27, independent but rotating at the same speed.
- the rollers 25 come into contact with a rib 17a projecting from the hoop 17 surrounding the tank and delimiting the dry compartment.
- the textile products introduced into compartment C1 of the drum 3 through a chute 28 are first treated in this compartment.
- This treatment consists, in known manner, of rotating the drum by a fraction of a turn and alternately in one direction or the other to obtain the desired bubbling effect.
- the drum is rotated over one complete revolution in the direction of arrow 33 in FIG. 3, so that the perforated shovel 8 takes the textile products and ensures their drainage before transferring them to the next compartment.
- the treated textile products are discharged through an outlet chute 30 directing them to a receiving tank, not shown.
- This machine combines the advantages of modular tunnel machines with those of sequential tunnel machines, without having the disadvantages of these machines, namely, respectively, in terms of the cost of installation and maintenance, and in terms of the mixing of the conducting baths. high consumption of water and detergent, but also insufficient washing.
- Such a machine can therefore be used to wash any type of dirty laundry, whether soiled, very soiled or particularly soiled.
- the excellence of the mechanical washing obtained makes it possible to limit the number of compartments compared to known devices, which leads to a gain on investment, on space, on the consumption of products, and on the time of washing.

Abstract
Description
La présente invention concerne une machine pour le traitement en continu de pièces textiles ou autres. Cette machine vise plus particulièrement, quoique non exclusivement, le lavage et le rinçage des pièces textiles.The present invention relates to a machine for the continuous treatment of textile or other parts. This machine is aimed more particularly, although not exclusively, at washing and rinsing textile parts.
On connaît une machine pour ce genre de traitement comportant un tambour muni d'une paroi cylindrique perforée et monté rotatif autour d'un axe horizontal à l'intérieur d'une cuve, et dans laquelle l'espace en section annulaire ménagé entre le tambour et le fond de la cuve, et qui est destiné à recevoir et transmettre à l'intérieur du tambour, à travers les perforations de sa paroi cylindrique, les liquides de traitement, est divisé par des collerettes intérieures en contact étanche, par des joints, avec la paroi cylindrique du tambour, en autant de compartiments qu'il y a de liquides de traitement, tandis que sont prévus, à l'intérieur du tambour, des moyens d'entraînement des pièces textiles, parallèlement à l'axe du tambour, depuis son extrémité d'entrée jusqu'à son extrémité de sortie, d'autres moyens étant prévus à l'extérieur du tambour pour son entraînement en rotation pendant le traitement.A machine is known for this type of treatment comprising a drum provided with a perforated cylindrical wall and rotatably mounted around a horizontal axis inside a tank, and in which the space in annular section formed between the drum and the bottom of the tank, which is intended to receive and transmit to the interior of the drum, through the perforations of its cylindrical wall, the treatment liquids, is divided by internal flanges in tight contact, by seals, with the cylindrical wall of the drum, in as many compartments as there are treatment liquids, while there are provided, inside the drum, means for driving the textile pieces, parallel to the axis of the drum, from its inlet end to its outlet end, other means being provided outside the drum for its rotational drive during the treatment.
Dans cette machine connue, aussi dénommée tunnel séquentiel et dont une forme d'exécution est décrite dans la demande de brevet allemand DE-A-3 903 458, les moyens d'entraînement des pièces textiles, à l'intérieur du tambour sont constitués par une virole en hélice, solidaire de la face interne du tambour et s'étendant de l'une à l'autre de ses extrémités.In this known machine, also known as a sequential tunnel and an embodiment of which is described in German patent application DE-A-3,903,458, the means for driving the textile pieces inside the drum are constituted by a helical ferrule, integral with the internal face of the drum and extending from one to the other of its ends.
Il en résulte que cette virole en hélice pousse, vers l'avant, non seulement les pièces en cours de traitement mais aussi les différents liquides de traitement qui, à la sortie du tambour, sont intimement mélangés, ce qui, évidemment, nuit à la qualité du traitement. En outre, les pièces textiles, surtout si elles sont susceptibles d'être imprégnées par les liquides de traitement, participent aussi à ce transfert et à ce mélange des liquides, car elles ne sont jamais extraites des bains formés par ces liquides dans le fond du tambour.As a result, this helical ferrule pushes forward not only the parts being treated but also the various treatment liquids which, at the outlet of the drum, are intimately mixed, which, obviously, harms the quality of treatment. In addition, the textile pieces, especially if they are likely to be impregnated with the treatment liquids, also participate in this transfer and this mixing of the liquids, because they are never extracted from the baths formed by these liquids in the bottom of the drum.
Par ailleurs, dans cette machine, l'entraînement du tambour est assuré par des frettes qui, fixées à ses extrémités dépassant de la cuve, forment des chemins de roulement en appui sur des galets de support, dont au moins un est moteur.Furthermore, in this machine, the drum is driven by hoops which, fixed at its ends projecting from the tank, form raceways bearing on support rollers, at least one of which is powered.
Cette disposition augmente considérablement la longueur du tambour et, par là, les difficultés d'obtention d'une raideur axiale suffisante, entre les frettes par lesquelles il est supporté.This arrangement considerably increases the length of the drum and, thereby, the difficulties of obtaining sufficient axial stiffness, between the hoops by which it is supported.
On connaît aussi, comme décrit dans la demande de brevet français FR-A-2 277 176, une machine dite modulaire et composée de plusieurs éléments indépendants, comportant, chacun une cuve, un tambour, des moyens d'entraînement particulier du tambour, et une pelle de transfert servant au passage des pièces textiles d'un élément à un autre. Cette construction qui rend indépendant chaque élément et lui permet donc d'effectuer des cycles de rotation différents de ceux des autres éléments, tout en séparant les bains, se révèle très onéreuse à réaliser ne serait ce que par le nombre élevé de moteurs indépendants et de moyens de guidage en rotation des éléments.Also known, as described in French patent application FR-A-2 277 176, is a so-called modular machine composed of several independent elements, each comprising a tank, a drum, special drive means for the drum, and a transfer shovel for the passage of textile pieces from one element to another. This construction which makes each element independent and therefore allows it to carry out cycles of rotation different from those of the other elements, while separating the baths, proves to be very expensive to realize even if only by the high number of independent motors and means for guiding the elements in rotation.
La présente invention a pour but de remédier aux inconvénients des tunnels séquentiels et des tunnels modulaires en fournissant une machine qui, séparant les bains et, égouttant les pièces textiles entre les différentes phases du traitement, soit peu onéreuse à réaliser et conduise à des frais d'entretien réduits.The object of the present invention is to remedy the drawbacks of sequential tunnels and modular tunnels by providing a machine which, separating the baths and, draining the textile pieces between the different phases of the treatment, is inexpensive to carry out and leads to costs of '' reduced maintenance.
Cette machine est du type comportant un tambour muni d'une paroi cylindrique perforée et monté rotatif autour d'un axe horizontal à l'intérieur d'une cuve, et dans laquelle l'espace annulaire ménagé entre le tambour et le fond de la cuve, pour recevoir et transmettre à l'intérieur du tambour, les liquides de traitement, est divisé par des collerettes intérieures en contact étanche, par des joints, avec la paroi cylindrique du tambour, en autant de compartiments qu'il y a de liquides de traitement, tandis que sont prévus, à l'intérieur du tambour, des moyens d'entraînement des pièces textiles, parallèlement à l'axe du tambour, depuis son extrémité d'entrée jusqu'à son extrémité de sortie, d'autres moyens étant prévus à l'extérieur du tambour pour son entraînement en rotation pendant le traitement.This machine is of the type comprising a drum provided with a perforated cylindrical wall and rotatably mounted around a horizontal axis inside a tank, and in which the annular space formed between the drum and the bottom of the tank , to receive and transmit inside the drum, the treatment liquids, is divided by internal flanges in tight contact, by seals, with the cylindrical wall of the drum, in as many compartments as there are treatment, while there are provided, inside the drum, means for driving the textile pieces, parallel to the axis of the drum, from its inlet end to its outlet end, other means being provided outside the drum for its rotational drive during treatment.
Selon l'invention, les collerettes internes sont annulaires, divisent le tambour en autant de compartiments successifs que la cuve, et sont rigidement fixées avec les extrémités de nervures longitudinales qui sont fixés à la face interne de la paroi cylindrique de chaque compartiment du tambour parallèlement aux génératrices de cette paroi, qui entraînent en rotation les piéces textiles assurant leur brassage efficace dans chaque bain de traitement qui sont espacées angulairement dans chaque compartiment et sont alignées avec celles des autres compartiments pour former, par arc-aboutement entre elles, des longerons de rigidifications du tambour,
- tandis que d'une part, les moyens de transfert des pièces en cours de traitement d'un compartiment au suivant du tambour sont constitués par une pelle tronconique perforée s'étendant vers l'amont depuis l'orifice circulaire de sortie de chaque compartiment, en embrassant au moins la demi-circonférence, jusqu'à son orifice entrée, l'extrémité longitidunale antérieure de cette pelle, vue dans son sens de rotation, étant au contact de la face interne de la paroi cylindriquedu tambour,
- et que d'autre part, les deux compartiments secs sont formés entre les compartiments humides, respectivement latéral et central de la cuve, et constituent chacun un logement pour les moyens d'entraînement et de support du tambour.
- while on the one hand, the means for transferring the pieces being treated from one compartment to the next of the drum consist of a perforated frustoconical shovel extending upstream from the circular outlet orifice of each compartment, by embracing at least the half-circumference, up to its orifice entered, the anterior longitudinal end of this shovel, seen in its direction of rotation, being in contact with the internal face of the cylindrical wall of the drum,
- and that on the other hand, the two dry compartments are formed between the wet compartments, respectively lateral and central of the tank, and each constitute a housing for the drive and support means of the drum.
Ainsi, avant chaque transfert d'un compartiment à l'autre, les pièces traitées sont extraites du bain par la pelle associée à ce compartiment et sont égouttées sur cette pelle avant d'être déposées dans le compartiment suivant.Thus, before each transfer from one compartment to another, the treated parts are extracted from the bath by the shovel associated with this compartment and are drained on this shovel before being deposited in the next compartment.
Afin de diminuer la distance entre les frettes du tambour par lesquelles celui-ci repose sur des galets de support et d'entraînement, la cuve comporte deux compartiments secs, c'est à dire isolés du bain, logeant les deux jeux de galets supports du tambours et leurs moyens d'entraînement en rotation, chaque frette du tambour étant fixé à ce dernier en correspondance de l'un de ces compartiments secs.In order to reduce the distance between the frets of the drum by which it rests on support and drive rollers, the tank has two dry compartments, that is to say isolated from the bath, housing the two sets of support rollers of the drums and their rotary drive means, each hoop of the drum being fixed to the latter in correspondence with one of these dry compartments.
Ces deux compartiments secs divisent la cuve en un élément central et deux éléments latéraux.These two dry compartments divide the tank into a central element and two lateral elements.
Dans une forme d'exécution de l'invention, chacune des extrémités de chacun des éléments de cuve, respectivement central et latéral, comporte un logement pour la fixation du talon d'un joint à lèvre dont la lèvre, tournée vers l'intérieur du compartiment annulaire formé entre l'élément de cuve et le tambour, est plaquée élastiquement contre la face externe d'une frette pleine, fixée sur la périphérie du tambour.In one embodiment of the invention, each of the ends of each of the tank elements, respectively central and lateral, has a housing for fixing the heel of a lip seal, the lip of which faces towards the inside of the annular compartment formed between the tank element and the drum, is pressed elastically against the external face of a solid hoop, fixed on the periphery of the drum.
L'invention sera mieux comprise à l'aide de la description qui suit en référence aux dessins schématiques annexés représentant, à titre d'exemple non limitatif, une forme d'exécution de cette machine.

De façon connue, cette machine est composée d'un tambour cylindrique 2, à paroi perforée, monté rotatif autour d'un axe horizontal à l'intérieur d'une cuve, désignée de façon générale par 3, et elle-même portée par un châssis 4. L'espace annulaire ménagé entre le tambour 2 et le fond de la cuve 3 est divisé, en plusieurs compartiments par des collerettes radiales internes 6, en contact étanche avec la paroi du tambour 2. Dans la forme d'exécution représentée, ces compartiments sont au nombre de dix et sont référencés C1 à C10.In known manner, this machine is composed of a
Selon l'invention, le tambour perforé 2 est divisé en autant de compartiments que ceux de la cuve par des collerettes annulaires internes 7, en forme de couronne s'opposant au transfert des liquides de traitement d'un compartiment à l'autre. Chaque collerette 7 est disposée dans le même plan diamétral que la collerette 6 qui lui correspond.According to the invention, the
Chaque compartiment comporte des moyens de transfert au compartiment suivant des pièces textiles en cours de traitement, moyens qui sont constitués par une pelle tronconique perforée 8. Pour chaque pelle, la base semi-circulaire 8a, de plus grand diamètre, embrasse au moins la demi-circonférence de l'orifice de sortie 9 du compartiment, tandis que son extrémité 8b, de plus petit diamètre, s'étend jusqu'à l'orifice d'entrée de ce compartiment. La figure 3 montre que l'extrémité longitudinale antérieure 8b de la pelle 8, qui est alors vu dans son sens de rotation, vient en contact avec la face interne de la paroi cylindrique du tambour 2, dont elle contribue à la rigidification.Each compartment includes means for transferring textile pieces during processing to the next compartment, means which consist of a perforated
Chaque compartiment du tambour 2 comporte, sur la face interne de ce tambour, des nervures 12 d'entraînement des pièces textiles. Ces nervures sont disposées parallèlement aux génératrices du tambour et sont décalées angulairement les unes par rapport aux autres. La figure 3 met en évidence que les deux nervures 12 disposées de part et d'autre de l'extrémité amont 8b de la pelle perforée 8 ont une moindre hauteur que les autres nervures.Each compartment of the
Comme le montre la figure 2, les nervures 12 de chacun des compartiments du tambour sont alignées avec celles des autres compartiments et sont rigidement fixées par leurs extrémités sur les collerettes 7 du tambour, de manière à former, par arc-boutement, des longerons rigidifiant le tambour et améliorant sa raideur en torsion, aidées en cela par les pelles 8.As shown in FIG. 2, the
Suivant une autre caractéristique importante de l'invention, la cuve 3 comporte deux compartiments secs S1 et S2 qui sont isolés du bain et qui constituent logements pour des moyens d'entraînement et de support du tambour. Dans la forme d'exécution représentée, ces compartiments secs sont réalisés dans les compartiments C3 et C8 de la cuve, mais ils peuvent bien entendu être situés dans tout autre compartiment, en fonction des contraintes exercées sur le tambour par les niveaux du liquide de traitement dans les divers compartiments, niveaux variant selon les compartiments. Avec cette structure, la cuve 3 est donc divisée en un élément central 3b et en deux éléments latéraux, respectivement 3a et 3c.According to another important characteristic of the invention, the
Comme le montre les figures 2 et 4, chacune des extrémités de chacun des éléments 3a-3b et 3c de la cuve est munie d'un logement 15 pour le talon 16a d'un joint à lèvres 16 dont la lèvre 16b, tournée vers l'intérieur de l'élément de la cuve, vient en contact d'étanchéité avec une frette fixée contre la paroi externe du tambour 2. Celui-ci comporte donc deux frettes 17, délimitant les compartiments secs et deux frettes extrêmes 18, fixées à ses extrémités.As shown in Figures 2 and 4, each end of each of the
La figure 4 montre que l'étanchéité entre les divers compartiments C1 à C10 de la cuve, au sein de chacun de ses éléments 3a-3b-3c, est assurée au moyen des collerettes internes 6, saillant radialement dans le compartiment et sensiblement dans le prolongement de la collerette 7 correspondant du tambour, et par des joints d'étanchéité, désignés de façon générale par 20. Le talon 20a de chaque joint est emprisonné par des couronnes annulaires 22 fixées sur des nervures 23 saillant de la périphérie du tambour. Les deux lèvres 20b du joint emprisonnent, par contact élastique et étanche, les bords externes de la collerette 6.FIG. 4 shows that the seal between the various compartments C1 to C10 of the tank, within each of its
Grâce à cet agencement, et comme le montre la figure 2, les différents compartiments C1 à C10 sont totalement indépendants les uns des autres, ce qui permet, pour chaque compartiment, de maîtriser parfaitement la composition du bain, son niveau et sa température.Thanks to this arrangement, and as shown in FIG. 2, the different compartments C1 to C10 are completely independent of each other, which makes it possible, for each compartment, to perfectly control the composition of the bath, its level and its temperature.
Au moins, un compartiment de la cuve est muni dans la partie supérieure de celle-ci d'une porte de visite 31 (figure 1) permettant, avec une autre porte de visite 32 (figure 2) ménagée sur le compartiment correspondant du tambour, d'accéder à l'intérieur du compartiment du tambour pour dégager les produits textiles formant un bourrage dans la goulotte ou dans le compartiment, en évitant d'avoir à franchir tous les compartiments amont ou aval, comme c'est le cas dans les tunnels actuels. Cette porte ou ces portes de visite sont disposées sur les compartiments sujets à des bourrages.At least one compartment of the tank is provided in the upper part thereof with an inspection door 31 (FIG. 1) allowing, with another inspection door 32 (FIG. 2) formed on the corresponding compartment of the drum, to access the interior of the drum compartment to clear the textile products forming a jam in the chute or in the compartment, avoiding having to cross all the upstream or downstream compartments, as is the case in tunnels current. This door or these inspection doors are arranged on the compartments subject to jams.
Dans la forme d'exécution représentée, les compartiments C1-C2 sont affectés au prélavage, représentés par l'accolade P à la figure 2, tandis que ceux C3 à C6 sont affectés au lavage, comme représenté par l'accolade L à la même figure et que ceux C7 à C10 sont affectés au rinçage, comme représenté par l'accolade R. Il est bien évident que cette répartition n'est pas impérative et peut être adaptée en fonction des besoins du traitement. Il en est de même pour le nombre de compartiments qui n'est pas limité à dix et qui, par exemple, peut varier de 8 à 16, en fonction des besoins.In the embodiment shown, the compartments C1-C2 are assigned to the prewash, represented by the brace P in FIG. 2, while those C3 to C6 are assigned to the washing, as represented by the brace L to the same figure and that those C7 to C10 are assigned to rinsing, as represented by the brace R. It is obvious that this distribution is not imperative and can be adapted according to the needs of the treatment. The same is true for the number of compartments which is not limited to ten and which, for example, can vary from 8 to 16, depending on requirements.
L'entraînement en rotation de la cuve, réalisé dans chacun des compartiments secs, est assuré par une paire de galets espacés 25, montés libres en rotation dans des consoles 26 du châssis 4 et reliés par des transmissions de mouvements, de type courroies trapézoïdales, crantées ou non, à des motoréducteurs 27, indépendants mais tournant à la même vitesse. Les galets 25 viennent en contact avec une nervure 17a saillant de la frette 17 ceinturant la cuve et délimitant le compartiment sec.The rotation of the tank, carried out in each of the dry compartments, is ensured by a pair of spaced
En fonctionnement, les produits textiles introduits dans le compartiment C1 du tambour 3 par une goulotte 28 sont d'abord traités dans ce compartiment. Ce traitement consiste, de façon connue, à faire pivoter le tambour sur une fraction de tour et alternativement dans un sens ou dans l'autre pour obtenir l'effet de barbotage recherché. A la fin de chaque phase de traitement, le tambour est entraîné en rotation sur un tour complet dans le sens de la flèche 33 de figure 3, de manière que la pelle perforée 8 prélève les produits textiles et assure leur égouttage avant de les transférer au compartiment suivant.In operation, the textile products introduced into compartment C1 of the
Il en est ainsi dans chaque bain, de sorte que, durant leur déplacement dans la machine, les produits textiles sont soumis à une succession de traitements, indépendants les uns des autres et sans influence les uns sur les autres, ce qui permet d'améliorer la qualité du traitement obtenu, sans altérer les bains et sans consommation excessive de bains.This is so in each bath, so that, during their movement in the machine, the textile products are subjected to a succession of treatments, independent of each other and without influence on each other, which makes it possible to improve the quality of the treatment obtained, without altering the baths and without excessive consumption of baths.
A la sortie de la machine, les produits textiles traités sont évacués par une goulotte de sortie 30 les dirigeant vers un bac de réception, non représenté.On leaving the machine, the treated textile products are discharged through an
Cette machine combine les avantages des machines à tunnel modulaire avec ceux des machines à tunnel séquentiel, sans présenter les inconvénients de ces machines, à savoir, respectivement, au niveau du coût d'installation et de maintenance, et au niveau du mélange des bains conduisant à des consommations importantes d'eau et de produit lessiviel, mais aussi à un lavage insuffisant.This machine combines the advantages of modular tunnel machines with those of sequential tunnel machines, without having the disadvantages of these machines, namely, respectively, in terms of the cost of installation and maintenance, and in terms of the mixing of the conducting baths. high consumption of water and detergent, but also insufficient washing.
Une telle machine peut donc être utilisée pour laver tout type de linge sale, qu'il soit souillé, très souillé ou particulièrement souillé. De plus, l'excellence du lavage mécanique obtenu permet de limiter le nombre de compartiments par rapport aux dispositifs connus, ce qui conduit à un gain sur l'investissement, sur l'encombrement, sur la consommation des produits, et sur le temps de lavage.Such a machine can therefore be used to wash any type of dirty laundry, whether soiled, very soiled or particularly soiled. In addition, the excellence of the mechanical washing obtained makes it possible to limit the number of compartments compared to known devices, which leads to a gain on investment, on space, on the consumption of products, and on the time of washing.
