Description

La présente invention a pour objet un dispositif permettant le déblocage automatique du tissu dans les machines à teindre en boyau.The present invention relates to a device allowing the automatic release of the fabric in casing dyeing machines.

Dans une machine à teindre en boyau, le boyau de tissu, refermé sur lui-même, présente une partie disposée dans la zone inférieure de la machine, immergée dans le bain de teinture, et constituant une partie stockée sensiblement sous forme d'un pliage accordéon, et une partie émergé située dans la zone supérieure de la machine, passant au contact de moyens de guidage et d'entraînement, assurant la mise en mouvement de la boucle constituée par le boyau.In a casing dyeing machine, the casing of fabric, closed on itself, has a part arranged in the lower zone of the machine, immersed in the dye bath, and constituting a part stored substantially in the form of a fold. accordion, and an emerged part located in the upper zone of the machine, passing into contact with guide and drive means, ensuring the setting in motion of the loop formed by the hose.

Les moyens d'entraînement du boyau sont constitués soit par un rouleau motorisé, encore appelé tournette, monté en partie haute de la machine, soit par des tuyères assurant un transport pneumatique, soit enfin par l'association d'une tournette et de tuyères.The hose drive means consist either of a motorized roller, also called a spinner, mounted in the upper part of the machine, or by nozzles ensuring pneumatic transport, or finally by the combination of a spinner and nozzles.

Il arrive que le tissu stocké dans le fond de la machine bascule sur lui-même et exerce une contrainte sur la partie du boyau sortant du bain, perturbant le bon déplacement du boyau, voire immobilisant celui-ci. Il en résulte des défauts de teinture, préjudiciables à la qualité du produit fini. Ce problème est particulièrement important dans le cas de machines comportant seulement des tuyères pour réaliser le dépla­cement du boyau, dont l'action sur celui-ci ne permet pas de surmonter une augmentation sensible de la résistance à la circulation du tissu, comme cela est parfois possible avec une tournette qui exerce une trac­tion mécanique sur le boyau.Sometimes the fabric stored in the bottom of the machine rocks on itself and exerts a stress on the part of the hose leaving the bath, disrupting the proper movement of the hose, or even immobilizing it. This results in dye defects, detrimental to the quality of the finished product. This problem is particularly important in the case of machines comprising only nozzles for carrying out the displacement of the hose, the action of which does not make it possible to overcome a significant increase in the resistance to circulation of the fabric, as is sometimes the case. possible with a turner which exerts mechanical traction on the hose.

La présente invention vise à remédier à cet inconvénient.The present invention aims to remedy this drawback.

A cet effet, le dispositif qu'elle concerne comprend en combi­naison et disposés sur le brin du boyau sortant de la zone de stockage, d'une part des moyens de contrôle de l'avance du boyau et d'autre part, des moyens aptes à exercer une traction sur ce brin du boyau dans le sens d'avance de celui-ci, lorsque les moyens de contrôle de l'avance du boyau détectent un arrêt de celui-ci.To this end, the device which it relates to comprises in combination and arranged on the strand of the hose leaving the storage area, on the one hand means for controlling the advance of the hose and on the other hand, suitable means to exert traction on this strand of the hose in the direction of advance thereof, when the means for controlling the advance of the hose detect a stop thereof.

Dès que le boyau s'arrête de circuler, par exemple en raison d'un effort exercé par un mauvais arrangement du boyau au fond de la machine, cet arrêt est détecté et une traction est exercée sur le boyau, dont la valeur est supérieure à celle des moyens assurant la circu­lation normale.As soon as the hose stops circulating, for example due to a force exerted by a bad arrangement of the hose at the bottom of the machine, this stop is detected and a traction is exerted on the hose, whose value is greater than that of the means ensuring normal circulation.

Selon une forme d'exécution de ce dispositif, les moyens de contrôle de l'avance du boyau sont constitués par un rouleau d'axe hori­zontal monté libre en rotation autour de son axe et au contact duquel passe le boyau de façon à l'entraîner en rotation lors de son mouvement de défilement, ce rouleau étant associé à un capteur de contrôle de son mouvement de rotation.According to one embodiment of this device, the means for controlling the advance of the hose are constituted by a roller with a horizontal axis mounted freely in rotation about its axis and in contact with which the hose passes so as to drive it in rotation during its movement of movement, this roller being associated with a sensor for controlling its movement of rotation.

Avantageusement le capteur de contrôle du mouvement de rotation du rouleau est constitué d'une part par un aimant fixé sur une face en bout du rouleau et excentré par rapport à celui-ci et d'autre part, par un capteur électro-magnétique fixé sur une paroi de la machine et placé sur le trajet de l'aimant, ce capteur électro-magnétique étant agencé pour fournir un signal si la fréquence des impulsions qu'il reçoit de l'aimant est inférieure à une valeur déterminée.Advantageously, the sensor for controlling the rotation movement of the roller is constituted on the one hand by a magnet fixed on an end face of the roller and eccentric relative to the latter and on the other hand by an electromagnetic sensor fixed on a wall of the machine and placed on the path of the magnet, this electromagnetic sensor being arranged to supply a signal if the frequency of the pulses which it receives from the magnet is less than a determined value.

Selon une forme d'exécution de ce dispositif, dans le cas où la zone de stockage du tissu est située à la partie inférieure de la ma­chine, il est agencé pour exercer une traction de bas en haut sur le boyau.According to one embodiment of this device, in the case where the tissue storage area is located at the bottom of the machine, it is arranged to exert traction from the bottom up on the hose.

Selon une autre caractéristique de l'invention les moyens aptes à exercer une traction de bas en haut sur le boyau sont situés en-dessous des moyens de contrôle du défilement du boyau, ce qui confère une efficacité maximale aux moyens exerçant une traction sur le boyau.According to another characteristic of the invention, the means capable of exerting traction from the bottom up on the hose are located below the means for controlling the movement of the hose, which gives maximum efficiency to the means exerting traction on the hose. .

Conformément à une forme d'exécution de ce dispositif, les moyens aptes à exercer une traction sur le boyau sont constitués par un anneau circulaire monté pivotant autour d'un axe diamétral et horizon­tal et susceptible d'être entraîné en rotation autour de cet axe, cet anneau étant disposé sur la trajectoire du boyau, et étant en conditions normales maintenu dans un plan horizontal, afin de permettre le passage sans frottements du boyau, et étant entraîné en rotation d'une valeur angulaire déterminée avant d'être ramené à sa position initiale, lorsque les moyens de contrôle de l'avance du boyau détectent un arrêt de celui-­ci.In accordance with one embodiment of this device, the means capable of exerting traction on the hose consist of a circular ring mounted pivoting about a diametral and horizontal axis and capable of being driven in rotation around this axis, this ring being disposed on the path of the hose, and being in normal conditions maintained in a horizontal plane, in order to allow the passage without friction of the hose, and being driven in rotation by a determined angular value before being brought back to its position initial, when the hose advance control means detect that the hose has stopped.

Conformément à une autre forme d'exécution de ce dispositif, les moyens aptes à exercer une traction sur le boyau sont constitués par une pince comportant deux mâchoires disposées dans un même plan horizontal et placées de part et d'autre du boyau lorsqu'elles sont en position ouverte, correspondant à une avance régulière du boyau, et susceptibles de se refermer sur celui-ci avant d'être déplacées verticale­ ment d'une valeur déterminée, puis de nouveau dans l'autre sens après ouverture, lorsque les moyens de contrôle de l'avance du boyau détectent un arrêt de celui-ci.In accordance with another embodiment of this device, the means capable of exerting traction on the hose are constituted by a clamp comprising two jaws arranged in the same horizontal plane and placed on either side of the hose when they are in the open position, corresponding to a regular advance of the hose, and capable of closing on it before being moved vertically ment of a determined value, then again in the other direction after opening, when the means for monitoring the advance of the hose detect a stop of the latter.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé, représen­tant, à titre d'exemple non limitatif, une forme d'exécution de cette machine :

  • Figure 1 en est une vue en coupe transversale ;
  • Figure 2 est une vue très schématique de côté d'un dispositif de déblocage du tissu conforme à l'invention ;
  • Figure 3 est une vue de face de ce dispositif ;
  • Figure 4 est une vue de côté de ce dispositif en période de déblocage du tissu.
In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing, representing, by way of nonlimiting example, an embodiment of this machine:
  • Figure 1 is a cross-sectional view;
  • Figure 2 is a very schematic side view of a tissue release device according to the invention;
  • Figure 3 is a front view of this device;
  • Figure 4 is a side view of this device during the tissue release period.

La figure 1 représente très schématiquement une machine à teindre en boyau désignée par la référence générale 2, dans laquelle le boyau 3 de tissu refermé sur lui-même présente une partie 4 disposée dans la zone inférieure de la machine et immergée dans le bain de tein­ture 5. La partie émergée du boyau passe sur un rouleau supérieur moto­risé 6 disposé dans la zone supérieure de la machine, cette dernière étant équipée, de façon connue, d'un système d'aspersion 7 du boyau à l'aide de bain repris dans le fond de la machine.FIG. 1 very schematically represents a casing dyeing machine designated by the general reference 2, in which the casing 3 of fabric closed on itself has a part 4 arranged in the lower zone of the machine and immersed in the dye bath 5. The emerged part of the hose passes over a motorized upper roller 6 disposed in the upper zone of the machine, the latter being equipped, in known manner, with a spraying system 7 of the hose using the bath taken up in the bottom of the machine.

Conformément à la caractéristique essentielle de l'invention, cette machine est équipée, au niveau du brin du boyau sortant du bain, de moyens de déblocage du tissu comprenant un rouleau 8 d'axe horizon­tal, monté libre en rotation autour de son axe et au contact duquel passe le boyau en formant un angle de façon à pouvoir entraîner en rotation le rouleau lors de son mouvement de défilement.In accordance with the essential characteristic of the invention, this machine is equipped, at the level of the hose leaving the bath, with means for unlocking the fabric comprising a roller 8 with a horizontal axis, mounted to rotate freely about its axis and at contact from which the hose passes by forming an angle so as to be able to rotate the roller during its movement of movement.

Comme montré à la figure 3, le rouleau 8 est équipé d'un cap­teur de contrôle de son mouvement de rotation constitué, dans la forme d'exécution représentée au dessin, par un aimant 9 fixé sur l'une de ses faces en bout, et excentré par rapport au rouleau, et par un capteur électro-magnétique 10 fixé sur une paroi de la machine et placé sur le trajet de l'aimant 9, ce capteur électro-magnétique étant agencé pour fournir un signal si la fréquence des impulsions qu'il reçoit de l'ai­mant est inférieure à une valeur déterminée.As shown in FIG. 3, the roller 8 is equipped with a sensor for controlling its rotational movement constituted, in the embodiment shown in the drawing, by a magnet 9 fixed on one of its end faces, and offset from the roller, and by an electromagnetic sensor 10 fixed to a wall of the machine and placed on the path of the magnet 9, this electromagnetic sensor being arranged to provide a signal if the frequency of the pulses that 'it receives from the magnet is less than a specified value.

En-dessous du rouleau 8, est disposé un anneau 11 circulaire qui, comme montré au dessin, est traversé sans frottement par le boyau. Cet anneau 11 est monté pivotant autour d'un axe horizontal et diamétral 12 susceptible d'être entraîné en rotation par un moteur électrique ou d'autres moyens non représentés au dessin.Below the roller 8, is disposed a circular ring 11 which, as shown in the drawing, is crossed without friction by the hose. This ring 11 is pivotally mounted about a horizontal and diametral axis 12 capable of being rotated by an electric motor or other means not shown in the drawing.

En pratique, lorsque le rouleau 8 contrôle un défilement normal du tissu, l'anneau 11 demeure dans un plan horizontal et laisse passer librement le boyau. Si, au contraire, à la suite d'un mauvais arrangement du boyau dans le bain 5, la tournette 6 n'exerce plus une traction suffi­sante pour assurer le défilement du boyau, le rouleau de contrôle 8 cesse de tourner ou tourne à une vitesse insuffisante, ce qui est détecté par le capteur 10 qui commande alors la mise en rotation de l'anneau 11. Cette rotation se traduit, comme montré à la figure 4, par un effort de traction de bas en haut sur le boyau. Après un angle de rotation de valeur déterminée, l'anneau 11 revient dans sa position de départ. Si le rouleau 8 contrôle un défilement normal du boyau, l'anneau 11 demeure dans cette position. Si, au contraire, le boyau est toujours bloqué, l'anneau est de nouveau entraîné en rotation pour exercer une nouvelle traction sur le boyau.In practice, when the roller 8 controls normal movement of the fabric, the ring 11 remains in a horizontal plane and lets the hose pass freely. If, on the contrary, following a poor arrangement of the hose in the bath 5, the spinner 6 no longer exerts sufficient traction to ensure the passage of the hose, the control roller 8 stops rotating or rotates at a speed insufficient, which is detected by the sensor 10 which then controls the rotation of the ring 11. This rotation results, as shown in Figure 4, by a tensile force from bottom to top on the hose. After an angle of rotation of determined value, the ring 11 returns to its starting position. If the roller 8 controls normal movement of the hose, the ring 11 remains in this position. If, on the contrary, the hose is still blocked, the ring is again rotated to exert a new traction on the hose.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un dispositif de conception simple susceptible d'assurer automatiquement le déblocage du boyau de tissu lors de l'arrêt du défilement régulier de celui-ci.As is clear from the above, the invention brings a great improvement to the existing technique by providing a device of simple design capable of automatically ensuring the release of the fabric hose when the regular scrolling thereof stops.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce dispositif, décrite ci-dessus à titre d'exemple ; elle en embrasse, au contraire, toutes les variantes de réalisation.It goes without saying that the invention is not limited to the sole embodiment of this device, described above by way of example; on the contrary, it embraces all of its variant embodiments.

C'est ainsi notamment que les moyens destiné à exercer une traction sur le boyau pourraient être constitués par une pince se refer­mant sur le tissu et actionnée alternativement de bas en haut ou par tout autre système actionné électriquement, pneumatiquement, hydrau­liquement ou mécaniquement, ou encore que la zone de stockage du tissu pourrait être située non pas dans la partie inférieure, mais dans la partie supérieure de la machine, sans que l'on sorte pour autant du cadre de l'invention.Thus in particular that the means intended to exert a traction on the hose could be constituted by a clamp closing on the fabric and actuated alternately from bottom to top or by any other system actuated electrically, pneumatically, hydraulically or mechanically, or even that the fabric storage area could be located not in the lower part, but in the upper part of the machine, without departing from the scope of the invention.
