Definitions

  • the invention relates to a dobby loom and a Method for controlling a dobby loom according to the Preamble of the respective independent patent claim.
  • Known dobby looms include a loom for Entry of a weft as well as a dobby as Device for forming the shed.
  • the weaving machine and the dobby are usually about one Transmission device, for example via a Coupling and a gearbox, can be coupled and have a common in the coupled state Powertrain on.
  • This common driveline will by means of a drive - usually by means of a Motors - in turn drives and drives both Loom as well as the dobby.
  • Shaft weaving machines of this type have the disadvantage that that an engine with high power output is required is, especially when driving a large one Dobby (e.g. due to a large number heavy heald frames or through a large weave width). Furthermore varies both in the weaving machine as well with the dobby the freewheel required Torque, depending on the angle of rotation (current circulation position). Most of all, this will be caused by various oscillating mass-related components of the individual machines. With increasing size of the dobby and with the increasing speed of the weaving machine increases this induced load on the entire drive train, especially between the loom and Part of the drive train arranged in a dobby, but also the load on the engine. In addition comes that the required torque is additional depends on other operating parameters, e.g. of the Speed, of the type of fabric or of the fabricated Template.
  • one of the drive of the Auxiliary motor for the weaving machine Jacquard device and provide the drive shaft the loom with the drive shaft of the Jacquard device via a synchronization wave couple.
  • the drive shaft is by means of this auxiliary motor the jacquard device can also be driven.
  • the Auxiliary motor is used - with appropriate control Relief of the drive of the weaving machine, as well as Relief of the entire drive train. At the same time provides the synchronization wave for a more or less good synchronization of weaving machine and Jacquard facility.
  • an angle encoder provided that the respective circulation position of the The drive shaft of the jacquard device is detected and feeds a controller.
  • the controller determines-in Knowledge of the desired weaving pattern and knowledge the torques required at the respective angle of rotation (The required torques must therefore be the control for every angle of rotation before the machine starts be known) - that to be applied by the auxiliary engine Torque to drive the loom as well relieve the entire drive train.
  • the shaft loom according to the invention is the sensor or Parts of it (e.g. a strain gauge arrangement) arranged the drive train.
  • the sensor or Parts of it e.g. a strain gauge arrangement
  • the representative size for that at the respective time torque applied directly on the drive train are and will not be falsified.
  • the torque does not have to be on any elaborate detours can be determined.
  • a sensor that comes into question in particular is the an electrical signal in function of the actually torque applied, so for example a Sensor comprising a strain gauge assembly.
  • the strain gauge arrangement is directly on arranged the drive train.
  • the sensor has to also a suitable transmission element (a Transmitter) for transmitting the signal from the in operation rotating drive train to one in operation have fixed machine parts.
  • a Strain gauge assembly located on the drive train is arranged, is therefore particularly suitable to detect the torque because its output signal is directly proportional to the torque applied (Alternatively, sensors are also suitable for measuring Shear stresses). The applied torque can thus quickly and unadulterated from the sensor signal be won.
  • At least one sensor between the loom and the dobby or in this area adjacent end regions of the weaving machine and the Dobby is arranged on the drive train applied torque and a corresponding Signal fed to a regulation. Because of this signal the auxiliary drive is controlled by the control that fluctuations in between the weaving machine and the Torque applied to the dobby. This eliminates the effort already mentioned above reinforcement of the main drive and parts of the Drive train, especially of shafts, bearings, Gearboxes and clutches avoided.
  • the output signal of sensors 7 and 8 is fed to control 9 by means of signal lines, which in turn the motor 6 via a signal line 10, that is, the auxiliary drive.
  • the control of the Motor 6 through the control 9 takes place so that Fluctuations in between the weaving machine 1 and the Dobby 2 applied torque and / or Fluctuations in the speed can be reduced.
  • the solution according to the invention is also regarding of the total energy consumption (this is the one to be used Total power required for the generation of the Torque is required), cheap. This depends causally related to the mechanical coupling.
  • the energy would have to Synchronization of the two machines completely from the Drives of the machines are provided (at opposing movement tendencies would have to be Driving motor braking, the other driving act), which with corresponding implementation losses (at the motors).
  • Driving motor braking the other driving act
  • the mechanical Coupling are the same Movement tendencies at least partially over the mechanical coupling of loom and dobby from (which manifests itself e.g. in a torsion).
  • a Doom loom with mechanical coupling between So loom and dobby is in this case cheaper than a shaft loom without mechanical Coupling.
  • a sensor applied to part 4 of the drive train that includes a strain gauge assembly.
  • a sensor On such a sensor is shown in principle in FIG. 2 (greatly enlarged).
  • the rest position 80a is included shown in dashed lines in Fig. 2.
  • the output signal of the Strain gauge assembly 80 is a measure of that Torsion of part 4 of the drive train and the torsion part 4 of the drive train is again a measure of the applied torque.
  • FIG. 5 shows another gear 14a, such as it also between the weaving machine 1 and the part 4 of the drive train can be provided.
  • the two Parts of the drivetrain are only excerpts here indicated, one recognizes an end piece 10a of the Weaving machine 1 coming part of the drive train and a End piece 40a of between loom 1 and Dobby 2 provided part 4 of the drive train.
  • the two end pieces are again in bearings 11a and 41a guided and by means of the radially interlocking Gears 12a and 42a mechanically coupled together.
  • a force or a torque from the gear 12a transferred to the gear 42a, so the part 4 of the Want to dodge drivetrain, but from the camp 41a prevented.
  • a force absorption sensor see Fig. 6
  • FIG. 6 finally shows schematically a sensor 72, which, for example, on bearings 11 and 11a (Fig. 4, Fig. 5) can be provided.
  • a sensor 72 acts when transmitting a force or a torque on part 4 of the drive train Force on the bearing 41 or 41a, since the drive train in the camp is led and can not evade.
  • the forces acting on the bearing 41a can be directed in the direction of arrows F1 and F2 detected by sensor 72 and open this way determines the force or torque be the corresponding force on the bearing caused.
