Definitions

  • the invention relates to a device for delay correction of a conveyed, in particular textile web according to the preamble of claim 1.
  • Finishing work on textile materials involves straightening fabrics and knits.
  • the weft threads or courses must be parallel and exactly at right angles to the longitudinal direction.
  • Straightening is achieved by a moving system of straight and curved rollers. These can also be attached directly to the spout outlet.
  • the warp is to be determined by means of suitable electronic scanning means. This measurement system designed in this way is followed by a mechanical system, namely the actual steep link with straightening roller, to which appropriate control commands are supplied.
  • a mechanical shot judge should have the property that the path of the goods through the straightening machine is as short as possible.
  • the scanning of the goods takes place in the known state of the art at the output of the leveler, wherein the tension of the goods within the leveler is adjustable.
  • the regulation of the straightening machine must be adapted in precision and speed to the scanning process and the material properties of the goods.
  • the local device comprises a combination of different straightening and deflection rollers and on the output side an arrangement of a measuring system, for example in the form of a camera.
  • a correction is carried out first via a first pair of rollers and then a further correction by means of a second pair of rollers.
  • the second pair of rollers is arranged downstream of the first pair of rollers in the direction of travel of the goods.
  • a disadvantage of the known straightening devices is the high number of guide rollers and the large amount of material to textile material which passes through the straightening machine until the control is active.
  • a long cycle time and a large amount of material of the web leads to quality losses in terms of straightening, i. It takes a certain time until the textile web has a satisfactory straightening quality and freedom from distortion.
  • the delay of the incoming, in particular textile, material web is determined both at the inlet of the leveler and at its outlet.
  • a first straightening roller assembly is presented starting from the determined delay at the inlet, in the sense of a control.
  • one or more further following straightening roller arrangements are likewise made via the determination of the distortion at the inlet in the sense of a control.
  • Each of the straightening roller assemblies is movable via a separate drive.
  • the scanning at the outlet has an outlet bridge with several, even in the direction of the goods width sliding scanning heads.
  • the residual distortions determined there are directed to the straightening roller arrangement located in front of the outlet bridge for their regulation.
  • the inlet-side rollers are placed through the inlet bridge and the local measuring system, and the outlet-side rollers are regulated by the outlet bridge and the measuring system there.
  • the respective straightening roll arrangements comprise a combination of skew and bow straightening rolls, so that overall the number of rolls is reduced in comparison with conventional straightening machines and the product content in the straightening machine is reduced. This is especially true for elastic fabric, e.g. Knitted fabric, an advantage, since within the machine lower voltages related to the goods are built.
  • the distortion correction device is much faster and more accurate in the straightening result compared to conventional straightening machines, which results from the combination of positions and rules.
  • the inlet rollers By placing the inlet rollers, the rough straightening work is already completed in the inlet area, so that only residual distortions must be corrected in the outlet roller area.
  • the extremely fast correction of the delays also results from the combination of digits and rules, as the machine detects large distortion changes already in the inlet and thus immediately brings the infeed rollers to the necessary position, without the material of the Fabric web first, as in the prior art, to lead to the measuring system in the area of the outlet.
  • the device according to the invention for distortion correction can be implemented as a kind of modular system in which the number of straightening roller arrangements can be extended in a modular manner in order to increase the straightening capacity. Furthermore, between the straightening roller arrangements, the number of guide rollers can be increased in order to increase the straightening path for stiffer materials, since otherwise such goods can not apply the straightening process necessary for the straightening process in excessively short distances.
  • the components required for straightening the textile material web are primarily formed by a combination of arcuate and beveled roll in the respective straightening roller arrangement or in the respective straightening module. Between the straightening roller assemblies, a movement of the web can be performed without additional guide rollers, so that in a very simple basic design only two guide rollers in the inlet scanning head bridge and two further guide rollers in the area of the spout Abtastkopfmaschine are necessary.
  • a spreader roll in an embodiment of the invention in the inlet or form a dancer roll group in the outlet.
  • Fig. 1 is assumed by a leveler, which consists of individual modules, which are arranged within a stable frame.
  • a first module is formed by an infeed delay scan 1, which is arranged in the area of the goods inlet of the straightening machine.
  • the infeed delay scan I consists of a scanning head bridge which comprises a plurality of photoelectric and / or optoelectronic measuring heads spaced over the width of the web. To adapt to the width of the web, the measuring heads on the Abtastkopfmaschine are also automatically, longitudinally displaceable.
  • Another module consists of a runout delay scan 2.
  • the infeed delay scan 1 registers the existing actual distortion of the supplied textile material web (see Fig. 3 , G). From the determined delay data, a control signal for the straightening modules 3 and / or 4 is provided.
  • the straightening result is increased overall, ie, the amount of a non-distortion-corrected web is reduced , From the default signal obtained by the in-run delay scan 1, also in connection with the type of materials supplied, For example, woven or knitted fabric, an adjustment parameter for the downstream leveling module 3 and / or 4 determined.
  • the first straightening module 3 includes at least one roller 3a in connection with a roller suspension 3b and a frame assembly 3c.
  • the frame assembly 3c is together with the roller in the plane of Fig. 1 pivotable.
  • the roller 3a can also be laterally raised or lowered.
  • the respective straightening module 3, 4 may be enclosed by a housing 3d or 4d.
  • the second straightening module 4 is constructed analogously to the straightening module 3 and in turn has a straightening roller 4a, a roller suspension 4b and adjusting devices or means for supporting the straightening module 4c.
  • the control of the third straightening module 5 is effected by an output signal of the run-out delay scan 2, which has measuring heads 2a in combination with an opposite light source.
  • the structure of the run-out delay scan 2 is substantially analogous to that according to run-in delay scan 1, which also comprises the measuring heads 1a with transmitted-light illumination units.
  • the active part of the respective measuring head can scan the front or the back of the web. Measurements are possible both in transmitted and reflected light.
  • a control loop is formed, that is, a still existing residual distortion is determined, and on the provision of a controlled variable to the straightening module 5, this delay is corrected, and Although until reaching a predetermined setpoint, ie it is continuously performed a target-IstVerrupt within the controlled system.
  • the first straightening module 3 eliminates nearly 50% of the existing strains. Another delay is then eliminated by the second straightening module 4 and the residual distortion then from the third straightening module 5. Overall, less material leaves the machine without direction.
  • the straightening modules 3, 4 and 5 with their mechanical elements, such as frames and / or adjusting devices, are subjected to a special color coding or have a correspondingly different color coating, for example in the order first straightening module 3 black, second straightening module 4 red, third straightening module 5 yellow.
  • the web G according to Fig. 1 arrives at the figuratively illustrated embodiment of the straightening machine via a spreader roller 7a and the guide rollers 7b and 7c in the scanning of the intake delay scan 1, comprising the measuring heads 1a, and the deflection roller 1b in the first straightening module 3.
  • a mechanical support 6 is provided which receives deflection rollers 2b.
  • a dancer roller assembly 8 comprising two dancer rollers 8a may optionally connect.
  • the dancer roller assembly 8 succeeds in setting a constant tension in the web, which is then led out via a guide module 9, comprising the rollers 9a and 8b, from the straightening machine and then, for example, reaches a clamping frame for fixing the weft position.
  • a first directional module 3 and / or 4 there is a first scanhead bridge for forming an infeed scan 1 and a second scanhead bridge for forming a runout delay scan 2.
  • the number of guide rollers 22 has been reduced to a minimum.
  • Fig. 3 shows a block diagram representation of the control of the directional modules 3, 4 and 5.
  • the infeed warp 1 detects the draft of the incoming web G and provides a control value which is also dependent on the type of material, e.g. Woven or knitted fabric, can be specified as a presettable meter.
  • This default value passes in the sense of a feedforward control on electronic control blocks 10 and 13, which cause a symbolically shown adjustment of the roller 11 via drive means 12.
  • the symbolically indicated roller 15 of the second straightening module 4 is also supplied, optionally with a modified signal, to an electronic control block 17 and activates the mechanical adjusting means 16.
  • the adjustment can be made electromechanically, but also hydraulically.
  • the third straightening module 5 with the straightening roller 19 shown symbolically also has adjusting means 20 which can be activated via the assemblies 21.
  • adjusting means 20 which can be activated via the assemblies 21.
  • a control loop is present.
  • the discontinuity-delay scanning 2 determined by means of measuring heads located on a Abtastkopfmaschine (not shown), the remaining residual distortion of the web G. Then the straightening roller 19 is driven and there is a Determine how far this control step has been successful in judging. If there is still a (lesser) delay, the regulation becomes active again.
  • the control circuit based on the straightening module 5 is symbolized by the dashed arrow.
