Definitions

  • the present invention relates to an automatic, self-centering straightening machine for a continuous fabric, coupled in line with textile finishing machines, or with a printing machine as shown in US-A-4 384 686.
  • Coupling in line with a fabric finishing machine or printing machine, a weft straightener aligned according to the axis of the finishing or printing machine, wherein the fabric unrolled from a feed fabric roll is treated in order to have the picks positioned perpendicularly to the warp threads, or to verify the alignment of the loops, is known.
  • correction actions determine the side shifting of the fabric inside the finishing or printing machine which cannot be easily controlled, and involve such an error of treatment or of printing, as to transversely invade, e.g., during the printing process, the selvedges of the same fabric, in a direction, or in the other.
  • a purpose of the present invention is to provide an automatic, self-centering straightening machine for a continuous fabric coupled in line either with a textile finishing machine, or with a printing machine, and makes it possible both to rapidly carry out the correct positioning, controlled instant by instant, of the fabric, maintaining it in line with the finishing or with the printing, and a correct operating of the straightening unit.
  • a further purpose is to be able to operate on a wide range of fabric widths, without being obliged to replace the straightening machine, or to operate and carry out mechanical adjustments of the various components of the straightening unit before beginning the processing, also as a function of the fact that most times it is necessary to process the fabric on the finishing machines, and, above all, on the printing machines, in a out-of-centre position relatively to the axis of the same machines, e.g., to print a trade name on the selvedges.
  • a self-centering straightening machine is generally indicated by the reference numeral 10, and is arranged to receive a continuous fabric 11, e.g., being unrolled from a roll 12, supported on a fabric roll holder car 47, and to feed it, through return rollers 13, to a printing machine 14, or to another textile finishing machine, such as a raising machine, and so forth, partially shown in Figures 1 and 3.
  • the centering device 17 is constituted by three rollers 18 on board of swinging side support rods or shoulders 19, the one of which is hinged in 20 onto the frame 15, and the other one of which is rotatably constrained to the stem of a hydraulic cylinder 21, so to act on the lateral shift on the vertical plane, and to be used for aligning the fabric 11.
  • the fabric 11 enters then a straightening unit, generally indicated by the reference number 22, wherein, besides return rollers 9, provided are, e.g., three corrector rollers for the diagonal deformations 23, on board of a swinging frame 25 motor-driven in 26, and two further corrector rollers for the curved deformations 27, individually motor-driven in 28.
  • a straightening unit generally indicated by the reference number 22, wherein, besides return rollers 9, provided are, e.g., three corrector rollers for the diagonal deformations 23, on board of a swinging frame 25 motor-driven in 26, and two further corrector rollers for the curved deformations 27, individually motor-driven in 28.
  • Said processing axis 35 is independent from the fabric 11 being processed, and exactly as a function of the height, or width, of the fabric, it is located in an out-of-centre position relatively to a central fixed axis 34 of the printing machine 14.
  • the framework 15 is mounted on wheels 36 running along tracks 37, said tracks 37 being also located transversely relatively to the fabric feed direction 11, and being constrained to a baseplate, or to the floor, indicated by the reference numeral 38; the framework 15 interacts with, and is moved by a translational drive means 39, such as a hydraulic cylinder.
  • the straightening machine 10 can hence be shifted relatively to the printing machine 14, in relation to the width of the fabric 11 which is being processed.
  • a central computer 40 is equipped with a control keyboard 41, and is operatively connected with a related display screen 42. Said central computer 40 results furthermore to be operatively connected, through a set of connection leads, with said hydraulic translational drive means 39, which is provided with a shift control element 43, such as an encoder, interacting relatively to a starting stop 44, in correspondence of which the machine according to the invention processes a fabric having the maximum width.
  • a shift control element 43 such as an encoder
  • a microprocessor 45 is connected, which is associated with the reading heads 29, and with the drive means 26 and 28 of the corrector rollers 23 and 27.
  • third detection means 46 are located in correspondence of the centering means 17, so to detect the alignment of the fabric 11 and transmit such information to the central computer 40, so that it can consequently actuate the hydraulic cylinder 21, determining the correction.
  • the fabric 11 is thus located out-of-center inside the printing machine 14, and is positioned with an edge thereof nearly in correspondence with the side edge of the same machine. In this position, the further third detection means 46 associated with the centering device 17 detect, and act according to commands coming from the computer 40 to line-up the fabric 11.
  • the further detection means 32 and 33 detect the opposite transversal ends of the fabric 11 as said fabric is processed, and can act, always through the computer 40, to modify the position of the framework 15 by means of the hydraulic actuator 39.
  • the means act, which detect the position of the picks and/of the alignment of the loops 29-30, and the relevant microprocessor 45.
  • the fabric roll holder 47 runs on further tracks, and is rigidly connected with the framework 15, so to be always perfectly aligned, eliminating any further initial adjustment and positioning of the fabric roll holder 47 relatively to the fixed positions 48.
