Abstract

1. A self-contained machine for the preliminary fullwidth and tensionless dipping of a fabric prior to its introduction into a treatment installation, of the kind comprising, on the one hand, two superposed rows of drums (6, 7) between which the fabric (1) is returned in order to pass between ramps (10) for the spingling of the vertical lengths (1') defined on this fabric by the said rows, and, on the other hand, a series of electric motors (9) for effecting the drive under a constant torque of the drums (6) of one of the rows, characterized in that placed on the feed circuit of the motors (9), of the type having variable speed and constant torque, is an auto-transformer (20) directly controlled by a compensating roller (14) disposed, in the manner known "per se", at the outlet of the drums (6, 7) of the two rows with a view to being subjected to alternating displacements as a function of the difference in the respective working speeds of the machine and of the treatment installation fed by this latter.

Description

)n sait qu'à la sortie des machines d'impression il est souvent nécessaire de procéder au lavage des tissus afin de les débarrasser de l'enduit ou "gomme" qui recouvre leur face imprimée. Ces enduits ou gommes peuvent être très résistants et l'on est alors obligé d'avoir recours, préalablement au Lavage proprement dit, à une opération de prétrempage destinée à ramollir la couche et à imprégner l'épaisseur du tissu afin 3e favoriser l'action ultérieure de netoyage.) We know that when leaving the printing machines it is often necessary to wash the fabrics in order to get rid of the coating or "gum" that covers their printed side. These coatings or gums can be very resistant and it is then necessary to have recourse, prior to the actual washing, to a presoak operation intended to soften the layer and to impregnate the thickness of the fabric in order to promote the action. subsequent cleaning.

Ce prêtrempage est ordinairement effectué à l'aide d'un appareillage disposé en amont de l'installation de lavage. Cet appareillage fonctionne de manière continue et il ne doit évidemment impliquer aucun ralentissement du fonctionnement de l'installation de lavage, si bien qu'il renferme une longueur de tissu très importante, de l'ordre de plusieurs dizaines de mètres. C'est ainsi qu'on a notamment proposé de renvoyer verticalement le tissu entre deux rangées superposées de tambours associés à des rampes d'aspersion. Chaque tambour exerce évidemment un effet de freinage important, de telle sorte que lorsqu'on appelle, par exemple à l'aide de rouleaux d'avance convenablement agencés, ledit tissu à la sortie de l'appareillage de prétrempage, il arrive fréquemment que par suite de la tension excessive ainsi appliquée à l'étoffe, celle-ci se plisse longitudinalement en même temps qu'elle se rétrécit de manière inadmissible.This pre-soaking is usually carried out using equipment placed upstream of the washing installation. This apparatus operates continuously and obviously should not involve any slowing down of the operation of the washing installation, so that it contains a very large length of fabric, of the order of several tens of meters. Thus it has been proposed in particular to send the fabric vertically between two superimposed rows of drums associated with spray bars. Each drum obviously exerts a significant braking effect, so that when, for example by means of suitably arranged feed rollers, it is called up at the outlet of the presoak apparatus, it frequently happens that by as a result of the excessive tension thus applied to the fabric, it folds longitudinally at the same time as it inadmissibly shrinks.

Aussi a-t-on songé à réaliser des machines dans lesquelles les tambours de l'une des rangées sont entraînés individuellement sous un couple constant, ces moyens d'entraînement étant placés sous la dépendance d'un rouleau compensateur à déplacement alternatif. Cependant les solutions proposées présentaient une complexité telle que le coût total de la machine était très élevé alors que la fiabilité de l'ensemble était par trop réduite.We have therefore thought of making machines in which the drums in one of the rows are driven individually under constant torque, these drive means being placed under the control of a compensating roller with alternating displacement. However, the solutions proposed presented a complexity such that the total cost of the machine was very high while the reliability of the assembly was too reduced.

La présente invention se propose de remédier à cet inconvénient en permettant la réalisation d'une machine autonome de prêtrempage qui assure le traitement des tissus sans tension et au large et dont la construction est remarquablement simplifiée.The present invention proposes to remedy this drawback by allowing the production of an autonomous priestly machine. page which ensures the treatment of fabrics without tension and broad and whose construction is remarkably simplified.

La machine suivant l'invention, du genre comprenant d'une part deux rangées superposées de tambours entre lesquelles le tissu est renvoyé afin de passer entre des rampes pour l'aspersion des lés verticaux définis sur ledit tissu par lesdites rangées, et d'autre part des moyens pour assurer l'entraînement, sous un couple constant, des tambours de l'une de ces rangées, est caractérisée en ce que les moyens d'entraînement sont constitués par une série de moteurs électriques du type à vitesse variable et à couple constant, sur le circuit d'alimentation desquels est placé un auto-transformateur directement commandé par un rouleau compensateur disposé, à la façon en soi connue, à la sortie des deux rangées en vue d'être soumis à des déplacements alternatifs en fonction de la différence des vitesses de travail respectives de la machine et de l'installation de traitement alimentée par celle-ci.The machine according to the invention, of the type comprising on the one hand two superimposed rows of drums between which the fabric is returned in order to pass between ramps for spraying the vertical strips defined on said fabric by said rows, and on the other part of the means for ensuring the drive, under a constant torque, of the drums of one of these rows, is characterized in that the drive means are constituted by a series of electric motors of the variable speed and torque type constant, on the supply circuit of which is placed a self-transformer directly controlled by a compensating roller arranged, in a manner known per se, at the exit of the two rows in order to be subjected to alternating displacements according to the difference in the respective working speeds of the machine and the treatment plant supplied by it.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 est une coupe verticale montrant schématiquement l'agencement général d'une machine de prétrempage établie conformément à l'invention.
  • Fig. 2 illustre à plus grande échelle le système pour la commande des moteurs électriques d'avance.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 is a vertical section schematically showing the general arrangement of a presoak machine established in accordance with the invention.
  • Fig. 2 illustrates on a larger scale the system for controlling electric advance motors.

En fig. 1 la référence 1 désigne le tissu à traiter par prétrempage. Ce tissu 1, prélevé à partir d'une réserve schématisée en 2, est renvoyé pour traverser successivement un poste 3 pour le déroulage des lisières et un poste de centrage 4, les dispositifs ou mécanismes prévus auxdits postes 3 et 4 étant bien connus en pratique et ne nécessitant de ce fait aucune description détaillée.In fig. 1 the reference 1 designates the fabric to be treated by presoaking. This fabric 1, taken from a reserve shown diagrammatically in 2, is returned to pass successively through a station 3 for unrolling the selvedges and a centering station 4, the devices or mechanisms provided for in said stations 3 and 4 being well known in practice. and therefore requiring no detailed description.

A sa sortie du poste de centrage 4 le tissu 1 passe à l'intérieur d'un bac 5 rempli éventuellement d'un produit liquide d'impre- gnation, puis il est guidé pour être successivement renvoyé verticalement entre deux rangées superposées de tambours référencés 6 et 7, lesquels déterminent ainsi sur ledit tissu une série de portions verticales ou lés l' orientés parallèlement les uns aux autres. Les tambours inférieurs 7 sont disposés au-dessus d'un bac 8, tandis que chacun des tambours supérieurs 6 est relié à un moteur électrique indépendant d'entraînement 9 du type asynchrone multipolaire, à couple constant.On leaving the centering station 4 the fabric 1 passes inside of a tank 5 possibly filled with a liquid impregnation product, then it is guided to be successively returned vertically between two superimposed rows of drums referenced 6 and 7, which thus determine on said fabric a series of vertical portions or they are oriented parallel to each other. The lower drums 7 are arranged above a tank 8, while each of the upper drums 6 is connected to an independent electric drive motor 9 of the asynchronous multipole type, at constant torque.

Chaque tambour supérieur 6 est surmonté par une rampe d'aspersion 10, l'ensemble des rampes 10 de la machine étant alimenté à partir d'une canalisation 8a prévue sur le bac inférieur 8 ; ce dernier recueille le liquide qui après pulvérisation par les rampes 10 ruisselle le long des les l' et il reçoit en outre un apport par une canalisation d'appoint 12, l'excès s'écoulant par un trop-plein 8b.Each upper drum 6 is surmounted by a spraying ramp 10, all of the ramps 10 of the machine being supplied from a pipe 8a provided on the lower tank 8; the latter collects the liquid which after spraying by the ramps 10 trickles along the l 'and it also receives a supply by an auxiliary pipe 12, the excess flowing through an overflow 8b.

A sa sortie du dernier tambour supérieur 6, le tissu 1 est renvoyé vers le haut, non pas par un tambour perforé 7, mais par un rouleau compensateur 14 (fig. 1) prévu substantiellement à mi-hauteur entre les rangées 6 et 7. Ce rouleau 14 est porté par des bras latéraux 15 articulés à la manière de fléaux sur des pivots 16 et ce sont les déplacements verticaux dudit rouleau 14 qui assurent la commande de la vitesse réglable des moteurs d'entraînement 9.On leaving the last upper drum 6, the fabric 1 is returned upwards, not by a perforated drum 7, but by a compensating roller 14 (fig. 1) provided substantially at mid-height between the rows 6 and 7. This roller 14 is carried by lateral arms 15 articulated in the manner of flails on pivots 16 and it is the vertical displacements of said roller 14 which control the adjustable speed of the drive motors 9.

A cet effet et comme illustré en fig. 2 l'un des deux bras pivotants 15 s'étend au-delà de son pivot 16 à l'opposé du rouleau 14 et sur cette partie dépassante 15a est attachée l'extrémité d'un câble 17 convenablement renvoyé par des poulies 18 et muni à son extrémité opposée d'un contrepoids de tension 19 qui n'équilibre que partiellement le poids en porte-à-faux du rouleau précité. Sur ce câble 17 est fixée l'armature mobile, schématisée en 20a, d'un auto-transformateur 20 branché sur le circuit électrique qui alimente l'ensemble des moteurs 9.To this end and as illustrated in fig. 2 one of the two pivoting arms 15 extends beyond its pivot 16 opposite the roller 14 and on this protruding part 15a is attached the end of a cable 17 suitably returned by pulleys 18 and provided at its opposite end from a tension counterweight 19 which only partially balances the overhanging weight of the aforementioned roller. On this cable 17 is fixed the mobile armature, shown diagrammatically at 20a, of an auto-transformer 20 connected to the electrical circuit which supplies all of the motors 9.

Il convient de noter que sur ce circuit électrique d'alimentation est également prévu un commutateur 21 dont l'organe mobile 21a est lié à l'un des deux bras pivotants 15 et est agencé pour venir actionner sélectivement quatre contacteurs convenablement branchés sur le circuit précité, ainsi qu'on le comprendra mieux lorsqu'on exposera plus loin le fonctionnement de la machine suivant l'invention.It should be noted that a switch 21 is provided on this electrical supply circuit, the movable member 21a of which is linked to one of the two pivoting arms 15 and is designed to selectively actuate four contactors suitably connected to the aforementioned circuit. , as will be better understood when we explain below the operation of the machine according to the invention.

Le tissu 1 renvoyé vers le haut par le rouleau compensateur 14 est rappelé vers le bas par un tambour final 6' entraîné par un moteur 9' (fig. 1) branché sur le même circuit général que l'ensemble des moteurs 9. Il traverse ensuite un mécanisme élargisseur 22, avantageusement constitué par deux cylindres ou "vis" à striures obliques, puis un dispositif centreur 23 de type classique, avant d'être finalement renvoyé à l'horizontale en 24 pour pénétrer dans l'installation de lavage associée à la machine de prêtrempage.The fabric 1 returned upwards by the compensating roller 14 is recalled downwards by a final drum 6 'driven by a motor 9' (fig. 1) connected to the same general circuit as all of the motors 9. It passes through then a widening mechanism 22, advantageously constituted by two cylinders or "screws" with oblique grooves, then a centering device 23 of conventional type, before being finally returned horizontally at 24 to enter the washing installation associated with the presoak machine.

Sur le plan du fonctionnement on comprend que le maintien au large du tissu 1 à travers l'ensemble de la machine est assuré par les mécanismes élargisseurs 3 et 22 prévu aux extrémités de ladite machine. Les essais ont démontré que tout rétrécissement intempestif du tissu 1 au cours du prétrempage était radicalement évité, en même temps que les dispositifs centreurs 4 et 23 opéraient la retenue correcte dudit tissu dans la partie centrale des tambours. Ce tissu se présente de manière parfaite à l'entrée de l'installation de traitement.In terms of operation, it is understood that the maintenance of the fabric 1 across the whole of the machine is ensured by the widening mechanisms 3 and 22 provided at the ends of said machine. The tests have shown that any untimely shrinking of the fabric 1 during the presoak is radically avoided, at the same time as the centering devices 4 and 23 operate the correct retention of said fabric in the central part of the drums. This fabric is perfectly presented at the entrance to the treatment facility.

On conçoit par ailleurs que l'entraînement de ce tissu 1 à travers toute la machine s'effectue sans tension puisque ledit tissu est déplacé par les tambours supérieurs 6 sur chacun desquels s'exerce un couple constant, quelle que soit la vitesse de rotation des moteurs 9. En conséquence le tissu 1 n'est soumis qu'à son propre poids et à un effort juste nécessai- 5re pour vaincre son inertie. La vitesse d'entraînement est commandée par les déplacements verticaux du rouleau compensateur 14 ; on conçoit en effet qu'en fonction des besoins de l'installation prévue en aval de la machine, c'est-à-dire en fonction de l'appel de tissu au niveau du cylindre de sortie 24, ce rouleau 14, enveloppé dans le dernier pli de tissu, va monter ou descendre suivant que la vitesse du travail de la machine de prétrempage est inférieure ou supérieure à celle de l'installation associée. Ces déplacements verticaux sont transmis par le câble 17 à l'auto-transformateur 20 qui commande en conséquence l'ensemble des moteurs 9 et 9' et ainsi la vitesse de rotation de chacun de ceux-ci, si bien que la machine se régule elle-même sans aucune intervention manuelle.It will also be understood that the drive of this fabric 1 through the whole machine is carried out without tension since said fabric is moved by the upper drums 6 on each of which a constant torque is exerted, whatever the speed of rotation of the motor 9. accordingly the fabric 1 is subjected to its own weight and a just 5 necessarily re effort to overcome its inertia. The drive speed is controlled by the vertical movements of the compensating roller 14; it is in fact conceivable that according to the needs of the installation provided downstream of the machine, that is to say according to the call for fabric at the outlet cylinder 24, this roller 14, wrapped in the last fold of fabric, will go up or down depending on whether the working speed of the presoak machine is lower or higher than that of the associated installation. These vertical displacements are transmitted by the cable 17 to the auto-transformer 20 which consequently controls all of the motors 9 and 9 ′ and thus the speed of rotation of each of them, so that the machine regulates it - even without any manual intervention.

Si toutefois la différence des vitesses de travail est à un moment donné très importante, l'organe mobile 21a du commutateur 21 vient actionner l'un ou l'autre (suivant que la vitesse de travail de la machine de prétrempage est supérieure ou au contraire inférieure à celle de l'installation de traitement) des deux contacteurs centraux, en court-circuitant de la sorte l'auto-transformateur 20 en alimentant directement les moteurs 9 et 9' au maximum dans un cas, et en coupant l'auto-transformateur 20, donc l'alimentation des moteurs 9 et 9', dans l'autre cas. La machine "récupère" ainsi rapidement la différence de vitesse et la régulation automatique par l'auto-transformateur 20 peut reprendre dans un laps de temps très court.If, however, the difference in working speeds is very significant at a given moment, the movable member 21a of switch 21 actuates one or the other (depending on whether the working speed of the presoak machine is higher or on the contrary lower than that of the treatment installation) of the two central contactors, thus short-circuiting the auto-transformer 20 by directly supplying the motors 9 and 9 'at most in one case, and by cutting the auto transformer 20, therefore the supply of motors 9 and 9 ', in the other case. The machine thus "quickly" recovers the speed difference and the automatic regulation by the auto-transformer 20 can resume in a very short period of time.

Si en dépit de cette commande par tout ou rien la "récupération" ne s'effectue pas et la différence de vitesses continue à s'amplifier, l'organe mobile 21a vient porter contre l'un ou l'autre des deux contacteurs latéraux du commutateur 21 qui provoque l'arrêt total de la machine. On réalise ainsi un système de sécurité efficace.If, despite this all-or-nothing command, the "recovery" does not take place and the speed difference continues to increase, the movable member 21a comes to bear against one or the other of the two lateral contactors of the switch 21 which causes the machine to stop completely. This provides an effective security system.

Il va de soi qu'on peut faire comporter à l'ensemble différents accessoires propres à améliorer le guidage du tissu à traiter, son déroulement régulier et son aspersion. De plus et bien que l'entraînement de chaque tambour 6 par un moteur séparé constitue la solution la meilleure, on peut évidemment relier plusieurs de ces tambours à un même moteur. On conçoit encore que l'invention est applicable à toute opération de prêtrempage de tissus, notamment en vue du blanchiment de ceux-ci.It goes without saying that the assembly can be made with various accessories suitable for improving the guidance of the tissue to be treated, its regular course and its spraying. In addition, and although driving each drum 6 by a separate motor constitutes the best solution, it is obviously possible to connect several of these drums to the same motor. It is also understood that the invention is applicable to any pre-soaking operation of fabrics, in particular with a view to bleaching them.

Il convient d'observer que le prix de revient de la machine suivant l'invention est bien inférieur à celui des machines classiques. Les moteurs à couple constant 9 et 9' sont bon marché et le système de rouleau compensateur et d'auto-transformateur qui assure leur commande évite d'avoir recours à des dispositifs de contrôle compliqués et coûteux.It should be noted that the cost price of the machine according to the invention is much lower than that of conventional machines. The constant torque motors 9 and 9 'are inexpensive and the compensating roller and auto-transformer system which controls them avoids the need for complicated and expensive control devices.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
