Definitions

  • the present invention relates to a device allowing the automatic release of the fabric in casing dyeing machines.
  • the fabric casing In a casing dyeing machine, the fabric casing, 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.
  • 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.
  • Document GB-A-1 396 364 describes a "jet" type dyeing machine, in which the control of the passage of the hose is controlled by a roller in contact with which the hose passes tangentially with a support without sliding under the action of '' a deflector which deflects the hose against the roller. In the event of a stop of the roller resulting from a stop in the passage of the hose, an unblocking attempt is made by reversing the direction of circulation of the dye liquid.
  • the present invention aims to remedy this drawback by providing a device ensuring, reliably and effectively, the release of the hose, in the event of the scrolling thereof being stopped.
  • the device it concerns comprising means for controlling the advance of the hose which, when a stop is observed, control an unlocking operation, is characterized in that it comprises, arranged on the strand of the hose leaving the storage area, means capable of exerting traction on this strand of hose in the direction of advance thereof , when the hose advance control means detect that the hose has stopped.
  • 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.
  • 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.
  • the tissue storage area 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.
  • 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. .
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the ring 11 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 bad 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.
  • 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.
  • 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 at the bottom, but at the top of the machine, without departing from the scope of claim 1.
