Definitions

  • the present invention relates to dyeing machines comprising two rollers on which the fabric to be dyed is wound.
  • the fabric passes from one roll to another while crossing the dye bath and thus impregnates with dye which gradually fixes itself on the fiber.
  • the object of the present invention is to obtain, on the wound fabric, after it has passed through the bath, a substantially constant rate of aging (percentage of bath contained in the fabric) from one end of the fabric to the other.
  • this control is performed electronically by controlling the direct current motor, which drives the tractor roller, to measure the acceleration ⁇ .
  • This product is performed electronically and is presented as a "measurement” to a motor speed controller so that the “Measurement” is equal to the acceleration setpoint.
  • the motor can be a direct current electric motor receiving an adjustable electromotive voltage by means of a thyristor variator.
  • the angular speed ⁇ of the winding cylinder as well as the number n of turns wound at each moment is detected by tachometric dynamo as above and the angular speed of the winding cylinder is adjusted so as to keep the expression ⁇ 2 constant (1 + n m-1 NOT ), m being the ratio of the final radius of the winding cylinder to its initial radius and N the number of turns of the fabric wound, at the end of the winding.
  • Another improvement which is also the subject of the invention and which pursues the same goal - obtaining a regular rearing rate over the entire surface of the fabric - concerns the small cylinders which guide the fabric to the point of winding (and unwinding) on the winding rollers.
  • These small cylinders press more or less on the fabric. They are each mounted on two articulated arms to be able to follow the variation of the diameter of the rollers. Now it happens that, either by wear of the bearings, or by a misalignment of the joints, the support of these cylinders on the roller which concerns them is no longer equal from one edge to the other of the fabric. It follows a different spin and a gradient of the color from one edge to the other.
  • Figure 1 is a schematic view of a JIGGER type dyeing machine.
  • FIG. 2 is a diagram illustrating an embodiment of the invention.
  • FIG. 3 schematically shows another embodiment of a regulation in accordance with the invention.
  • Figures 6 and 7 show in elevation and in perspective the mounting device of the small spin cylinder.
  • the machine shown in Figure 1 comprises a tank 1 filled with the dye bath 2 and through which passes the strip of fabric 3 to be dyed, this strip unwinding from a roller 4 to be wound on a roller 5.
  • This is the tractor roller and is driven in rotation by an electric motor with adjustable speed. Electric motors with electronic adjustment are currently well known.
  • a variable speed hydraulic transmission can also be used to drive the roller from the electric motor.
  • the strip of fabric is guided by passing over small cylinders 6 mounted mad on their axes. It also passes over an intermediate cylinder 7 placed above the dye bath and which it drives in rotation at the same time as a tachometric dynamo linked to this cylinder 7. This dynamo generates a signal proportional to the tangential speed of the roller 7 and therefore at the linear speed of displacement of the tissue, symbolized by v.
  • This motor can be a direct current motor supplied by a conventional thyristor variator.
  • the program is shown diagrammatically in FIG. 2 and can be implemented by any electronics engineer.
  • a computer is provided in which the values of m and N. are stored for each fabric during assembly.
  • an up-down counter is associated with each of the cylinders 4 and 5 and gives at each moment the number n of turns wound on that of the cylinders which is reel.
  • the number n is transmitted to the computer as well as the electric voltage, a measure of the angular speed ⁇ of the take-up cylinder.
  • the preferred embodiment of the invention which makes it possible to use simple electronic assemblies, is that in which the acceleration is controlled as a function, not of the product ⁇ .v, but of the sum a. ⁇ + v, a being a coefficient equal to R1 x m , R1 being the initial radius of the roller 5 and m the ratio of the final radius of this roller to its initial radius.
  • the signal a. ⁇ proportional to the angular speed ⁇ of the roller 5 is provided by the tachometric dynamo driven by the roller 5 (dynamo 8 in Figure 3).
  • This signal and that proportional to the linear speed v , supplied by the tachometric dynamo of the cylinder 7 are summed in the electronic device 9.
  • the corresponding signal is compared at 10 to the set value K and the resulting signal taken at 11 is sent to the motor servo device.
  • FIGS. 4 and 5 have been drawn by considering the numerical example in which the radius of the roller 5 varies between 1 and 3. In these figures, the radii have been plotted on the abscissa and the values of the centrifugal acceleration on the ordinate.
  • FIG. 5 shows the very large variation of the centrifugal acceleration for a radius of the roller 5 varying from 1 to 3 when it is sought to maintain constant the linear speed of the fabric, at a value which is in this example of the order of 70 meters per minute.
  • Curve 12 presents a maximum of 7.48 m / s2 for values of 6.9 m / s2 at the two extreme points.
  • FIGS. 6 and 7 there is shown on a larger scale, in elevation and in perspective, the small cylinder 14 which rests on the fabric where it is deposited on the roller 5.
  • This cylinder 14 which can rotate freely on its support ensures regular winding of the fabric leaving the dye bath.
  • the pins which constitute its axis are freely mounted in bearings 15 which are carried by two arms 16 pivotally mounted at 17 on the frame of the machine.
  • the arms 16 are interconnected by a braced tube 18 provided with flanges 19 fixed to the arms 16 by bolts 20. Between the flanges 19 is also arranged a bar with a V-section, called a "widening bar", over which the tissue. This bar is shown in 19a in FIG. 1 but not in FIGS. 6 and 7.
  • the cylinder 14 is held against the fabric which is wound on the roller 5, by the tension of the fabric as it passes over the widening bars, or by springs or by these means combined.
  • the illustrated embodiment provides for the passage of the assembly bolts 20, ovalized holes 21, both on the flanges 19 and on the arms 16 and, in addition, the bolts are not fully tightened, the nuts being braked by locknuts.
  • the arms 16 can take different inclinations relative to each other and in both directions by allowing the cylinder 14 to rest on the entire length of a generator.
