Definitions

  • the present invention relates to the field of textiles and more precisely it relates to a method for operating in parallel a plurality of machines for the production of chenille yarn. Furthermore, the invention relates to an operating unit that carries out this method.
  • Chenille yarn is made by a combination of a row of segments of weft yarn and a couple of continuous yarns, between which the segments are inserted transversally.
  • a torsion follows of the continuous yarns, called warp yarns, in order to keep steadily between them the transversal segments, called pile.
  • chenille yarn plants that have a plurality of machines in parallel, from each of which two chenille yarns exit, wound on respective spindles.
  • the spindles rotate continuously at a predetermined speed so that the respective chenille yarn is at the same time wound and twisted.
  • the pile segments are made by a continuous yarn wound on a substantially triangular gauge having a vertex oriented towards below at which a blade disk is arranged.
  • the yarn, spooled at high speed on the gauge forms a plurality of loops that proceed towards below and are eventually cut by the blade in a plane orthogonal to the loops same, creating thus two rows of pile segments.
  • Each row of pile segments is lowered following two separate paths, by means of counter rotating dragging rollers and are then inserted between the two warp yarns of each couple.
  • the contemporaneous transit of a couple of warp yarns and of pile segments at the edge of one of the dragging rollers, as well as the twisting action of the rotating spindles, causes the pile segments to be captured by the warp yarns and the automatic production of chenille yarn.
  • the driven axes in each machine are:
  • Machines for the production of chenille are well known that have three separate drives, of which one for axes a), b), c), one for head d) and one for the shaft of the spindles e).
  • machines are known that have a single operating unit And belt transmissions with gearboxes for operating the many axes.
  • the characteristics of the final yarn can be modified both changing geometrical parameters, for example the length of the pile segments or the position of the blade disk, and changing the ratio between the speeds of rotation of the many axes.
  • the first motor operates all the cylinder shafts, all the blades and all the dragging rollers of the various machines; the second motor operates all the heads and the third motor operates all the spindles.
  • the transmission of the movement from each motor to the respective power input joint of the various machines is carried out by means of belts or chains.
  • a method for actuating of a plurality of machines 1,2,... N for the production of chenille comprises the steps of:
  • the parameters of production of the chenille can be changed by simply adjusting the voltage/frequency of the first, and/or of the second, and/or of the third motor, according to predetermined tables of operation, and a new yarn, with different characteristics from the previous yarn can be obtained, which is homogeneous for each spindle spooled on the various machines.
  • each operating unit comprises an inverter circuit that produces a control signal for adjusting its output voltage/frequency according to a predetermined value.
  • inverter circuits can give to each motor an open loop constant predetermined supply with minimum deviations, without any servo controls, completely acceptable for a homogeneous production of a yarn of chenille.
  • Each motor can be switched off singularly from the supply. Therefore, for setting up or adjusting one of the machines 1, 2,...N it is sufficient to switch off the relative motors from the respective supplies. This can be done operating respective switches, stopping at the same time all the motors of that machine from the supply.
  • respective auxiliary drives may be provided.
  • the motors M i ', M i '',M i ''' of the machine that is supplied normally by operating units A', A'', A''', are commuted on auxiliary operating units A 1 ', A 1 '', A 1 ''', at the same voltage/frequency. Then the operating units A 1 ', A 1 '', A 1 ''' are run for reducing proportionally and progressively the speed up to stopping the machine I.
  • the operating units A 1 ', A 1 '', A 1 ''' are recycled until the motors M i ', M i '',M i ''' are at a steady speed rate, commuting eventually on operating units A', A'', A'''.
  • Auxiliary operating units A 1 ', A 1 '', A 1 ''' are then available for stopping a further machine or group of machines without stopping all the other machines.
  • a plant for the production of chenille comprises a plurality of machines 1,2,... N each having:
  • auxiliary operating units A 1 ', A 1 '', A 1 ''' are provided in parallel to the ordinary electrical supply so that the electrical supply of motors M i ', M i '', M i ''' is made independent and the machine can be set up or adjusted without stopping the other machines.
  • a machine for the production of chenille yarn comprises a spinning unit 10 from which two equal yarns 11 exit, wound on respective spindles 12; the latter rotate continuously at a predetermined speed for contemporaneously spooling and twisting the respective yarns 11.
  • the rotation of the spindles 12 is operated in a known way by a motor M''', at a respective power input joint 12b.
  • a reciprocating yarn guide 12a is provided, with separate drive.
  • the pile segments are obtained from a continuous yarn 13 wound by a spinning head 14 on a gauge 15 substantially triangular with vertex towards below.
  • the spinning head is brought into rotation by a motor M", at a respective power input joint 14a.
  • a blade disk 16 is arranged that forms two rows of pile segments that, by means of counter rotating dragging rollers 17, are brought into two respective zones where two warp yarns 18 and 19 of each couple are led.
  • the two couples of warp yarns 18 and 19 are fed by cylinder shaft 20 which, with blade 16 and pile dragging rollers 17, are brought into rotation by a motor M' through a respective power input joint indicated as a transmission shaft 21.
  • the voltages V', V" and V"' and the relative currents are supplied through lines 101, 102 and 103, by inverter circuits A', A", A'''. They can be inverters available on the market, for example of Mitsubishi type, of known operation and then not described in more detail.
  • Each motor is equipped with a protection circuit C.
  • the supply of the inverter from the network 140 is made through a start and safety circuit 141.
  • a control unit 142 is then provided comprising a circuit 143 of signals acquisition, a control and speed circuit 144 of the inverter and a processor 145, for example a CPU, a PLC or other microprocessor based electronics.
  • the input/output bus 146 and 147 communicate with an operating board 148 for setting the programs.
  • the inverters A', A", A"' operate in open loop.
  • FIG 5 a different embodiment is shown of the invention where three auxiliary operating units A 1 ', A 1 '', A 1 ''' are arranged in parallel to the main circuitry for the electrical supply of the motors M i ', M i '',M i ''' when the machine must be set up or stopped for maintenance without stopping the other machines.
  • a motor for example the motor M 2 '
  • All the motors M' were supplied with the same voltage/frequency V' by line 101.
  • the commutation can be done by switch 152, excluding motor M 2 ' from the V' supply and opening switch 152', thus commuting motor M 2 ' to auxiliary operating unit A 1 '.
  • operating unit A 1 ' which is also at voltage/frequency V', is run reducing proportionally and progressively the speed of the motor M 2 ' up to stopping the corresponding machine 2.
  • the same step is carried out contemporaneously with the other operating units A 1 '' and A 1 ''' for motors M 2 '' and M 2 '''.
  • the position of the motors in the machine can be different from that indicated.
  • a DC or AC supply is also possible from other types of known systems, according to the type of motors used, without departing from the extent of protection of the present invention.
