Definitions

  • the invention relates to the treatment of textile articles, in particular in the gas phase and in particular when these treatments are carried out on the looped article and the latter is accumulated in the form of folds and slides under the effect of its own weight. on a sliding surface. This is in particular the relaxation of knits, for example after dyeing.
  • Liquid phase treatments are known in which the looped textile article is deposited in folds and moves under the effect of its own weight on a sliding surface, while it is immersed in a dyeing or washing bath. . In such a liquid medium, the smooth, smooth movement of the article is facilitated by the damping of the liquid.
  • European patent application N O EP-A-0 078 747 the applicant has devised a method and a device for relaxing pieces of knitted fabric, which uses a sliding surface on which the knitted fabric is deposited in pleats and slides in gaseous medium, air or vapor.
  • the object of the method according to the invention is to remedy this drawback, to obtain regular movement of the article, and therefore to allow the speed of movement of the article to be increased.
  • Said method which ensures during a treatment the regular displacement of a textile article accumulated in folds and moving under the effect of its own weight along an inclined surface called sliding surface is characterized in that accompanies the movement of said article using a movable surface in contact with the upper part of the folds formed by the article.
  • the role of the moving surface is to support the article, this means that the speed of movement of this surface must be approximately equal to the linear speed that each point of the article takes when it slides normally, without particular shots along the inclined surface, under the effect of its own weight.
  • the method according to the invention is characterized in that the speed of movement of the movable surface remains approximately equal to said nominal speed, whatever the actual speed of movement of the article at a given instant. So when for some reason there is a jerk in the sliding of the article. the movable surface in contact with the upper part of the folds formed by the article acts either as an accelerator and drives the article if its speed tends to decrease, or as a brake and retains the article if its speed tends to increase. In practice, it is essentially an accelerator role that is played by the moving surface.
  • the method according to the invention is characterized in that the movement of the movable surface is momentarily accelerated when the speed of movement of the article is lower than its nominal speed, and this until this- be restored.
  • the movable surface moves at the same speed as the article, and it is only when the latter decreases significantly that the surface is given its role in driving the article.
  • the invention also relates to a device intended to ensure during a treatment the regular advancement of a textile article accumulated in folds and moving under the effect of its own weight along an inclined surface.
  • This device is characterized by an endless belt of which a portion of the outer surface is in contact with the upper part of the folds formed by the article, and moves in the same direction as the movement of the article.
  • the function of this carpet being to accompany the article in its movement, it is particularly advantageous that the linear speed of the carpet is never lower than the nominal speed of the article; Indeed, in the case where the linear speed of the article decreases and becomes lower than the nominal speed, the belt drives the article thanks to the friction forces between the external surface of the carpet and the upper part of the folds.
  • that of the rollers which support the endless belt and which is the driving roller has an axis equipped with a free wheel, and the linear speed given by the rotation of this motor axis is slightly less than the speed nominal.
  • the linear speed given by the rotation of this motor axis is slightly less than the speed nominal.
  • the belt is also driven by the article itself, but the drive roller is connected to a drive motor and includes a sensor movement, arranged so that when the speed of movement of the belt is significantly lower than the nominal speed, the sensor controls a momentary acceleration of the speed of rotation of the driving roller, for a time sufficient for the speed of the article to restore at said nominal speed.
  • the abnormal accumulation of folds at a given location on the inclined surface is counteracted by the sudden entrainment of the carpet.
  • an endless belt has been proposed, characterized in that each of the axes of the rollers which support it is mounted on a lever arm comprising a counterweight, so that the belt can without crushing absorb minor variations in thickness of the folds formed by the article during treatment, and in that said counterweight is provided with an adjustment device making it possible to vary the spacing between the belt and the sliding surface, and thus to take account of variations d thickness of the folds from one article to another. It is moreover preferable that all the points of the portion of carpet which are in contact with the upper part of the folds formed by the article are at an approximately constant distance from the sliding surface.
  • the textile article 1 during treatment in the gas phase is deposited in folds 2 on an inclined surface 3 constituted by a metal part along from which the folded article slides under the effect of its own weight.
  • the endless belt 4 is kept stretched between two rollers 5 and 6 whose axes 7 and 8 are mutually parallel and perpendicular to the direction of movement of the article 1 along the surface 3.
  • the roller 6 is powered, it drives the carpet 4 in a movement in the direction of the arrow S, so that the portion of the carpet whose outer surface 9 is in contact with the upper part 10 of the plies 2 of article 1 moves in the same direction as the article sliding along the surface 3 under the effect of its own weight.
  • the spacing e between the outer surface 9 of the mat where it is in contact with the article 1 and the inclined wall 3 is adjusted so that the folds formed by the article are not subject to crushing well that frictional forces are created between the outer surface of the mat and the article itself.
  • the axis 8 of the drive roller 6 is equipped with a free wheel 11 which is connected to a drive motor assembly 12-13 by a chain 14.
  • the belt and roller assembly has inertia very weak.
  • a given article will have a speed of displacement by sliding which will be a function of various parameters in particular the weight per square meter and the surface condition of the article; when the sliding takes place normally, without any particular incident, the article moves at a given speed, which we call nominal speed.
  • the rotation of the motor 12 is adjusted using the variator 13 so that it drives the belt at a linear speed slightly lower than said nominal speed.
  • the motor 12 positively drives the axis 8 and therefore the belt 4 at the predetermined speed, slightly lower than the nominal speed: thanks to the friction forces it is then article 1 which is driven by the displacement of the carpet 4. Under these conditions and very quickly, the jerk fades and the sliding of the article becomes normal again.
  • An alternative embodiment makes it possible to solve the problem of variations in the thickness of the folds of the article either of the same article being treated as a function for example of the state of dryness of the material, or for the treatment of different articles. on the same installation.
  • Each of the axes 7-8 of the rollers 5-6 supporting the endless belt 4 according to the invention is mounted on a lever arm 17-18 comprising a counterweight 19-20.
  • the assembly constituted by the belt 4, the support rollers 5-6 and their direct drive means (axes and freewheel) is balanced thanks to the effect of the counterweights 19 and 20, the latter are adjustable in displacement along of the lever arm 17-18.
  • This particular embodiment has several advantages. First of all, it makes it possible to absorb momentary variations in the thickness of the folds formed by the article during the same treatment.
  • the chain 14 is provided with a tensioner 29 making it possible to absorb the variations in distance between the driving wheel 30 and the receiving wheel 31.
  • the flatness of the endless belt 4 and the regularity of its application to article 1 can be ensured by plates 32 or any other means.
  • Knitting 1 is in the form of a closed loop; in the still wet state, it is thrown against the rigid element 21 after being driven at high speed by the assembly formed by the two belts 22 and 23 between which it is held flat.
  • the guide 33 placed opposite the rigid element 21 and positioned between the lower strand of the projection mat 22 and the upper strand of the retaining mat 4, forms with the rigid element 21 a chimney in which the knit 1 falls after it has been thrown against the rigid element 21.
  • the relaxation enclosure 25 also includes means for creating hot air, by example a fan exchanger assembly 26: the hot air is sent to the article 1 during treatment by means of lights 27 formed in the inclined wall 3; this arrangement allows intimate contact between the hot air and the article while it is tension free.
  • the inclined wall 3 has an angle of inclination of 30 degrees relative to the horizontal.
  • the outer surface of the endless belt 4 according to the invention is parallel to the wall 3 on the portion where it is in contact with the article.
  • the spacing e between the outer surface of the mat and the wall 3 can be between 5 and 30 centimeters.
  • the optimal spacing during processing is 15 to 20 centimeters; for a polyamide / cotton fleece weighing 320 grams per square meter, it is 18 to 22 centimeters.
  • this distance is automatically adjusted when the mat is mounted on a lever arm.
  • the endless belt 4 is made of an air-permeable material resistant to the temperature at which the treatment is carried out.
  • the roller 5, support of the mat 4 closest to the projection of the article against the rigid element 21, constitutes the movable wall of a chimney into which the knitted fabric falls, and the other wall of which consists of a curved surface 28 connecting the rigid element 21 and the inclined wall 3.
  • the inclined wall on which the textile article slides under the effect of its own weight has a certain radius of curvature over all or part of its length. .
  • the retaining mat is no longer supported by only two rollers, but by sufficient support means so that the external surface of the mat follows as much as possible the curvature of the wall and that the spacing is as much as possible. constant.
  • the term textile article designates any textile material (knitting, fabric, thread, etc.) whatever its presentation (looped pieces, pieces discontinuous, finished or semi-finished items ...); the term treatment also includes handling during which the articles do not undergo any particular transformations, except for displacing them. along the inclined surface.
