Definitions

  • the invention relates to a method for operating a loom with the features according to the preamble of patent claim 1, and to a drive arrangement for carrying out the method.
  • the weaving machine must be accelerated to at least a nominal operating speed within a limited angular range, e.g. At the first reed stop no contact points in the tissue arise.
  • Known drive arrangements of looms consist of a main electric motor, which is rotatably connected to a rotational flywheel and is connected via an electromechanically switchable clutch-brake unit with the main drive shaft of the loom.
  • This allows certain operating phases, such as the run-up and the shutdown of the loom perform advantageous by the engine and the additional flywheel masses offset from the other drive elements of the loom are accelerated or decelerated.
  • Such a drive arrangement is for example in the DE 37 33 590 A1 described.
  • the main engine is first accelerated with flywheel to a speed above the rated operating speed and subsequently the idler is engaged and accelerated by the flywheels at rated operating speed at idle running main engine. That is, the An infrastructureergie for the loom is essentially electrically driven; Applied to the loom coupleable flywheels.
  • wear occurs which has a negative effect, for example, with regard to the maintenance intervals.
  • the large flywheel with its inertia prevents rapid weakening of the loom by the drive motor within a limited angular range, which is advantageous or necessary in many situations, such as an emergency stop.
  • the disadvantage of this invention is an increased constructional and economic expense in that two separate drive motors are required.
  • the two motors must also be coordinated with each other in terms of control technology.
  • the separate drive for additional flywheel with associated power electronics increases the cost of this type of Aritreats arrangement.
  • Object of the present invention is to provide a method and a cost-effective drive assembly with flywheel for a weaving machine, which is dispensed with both a complex, wear-prone coupling brake unit, as well as a separate drive for a flywheel.
  • the stationary weaving operation and deceleration are a main motor, the main drive shaft of the loom and a rotatable additional flywheel with each other depending on the operating state of different operative connection.
  • the different active connections are adjusted clutch actuated by different switching states.
  • the two clutches are independently switchable. Each clutch can be dimensioned according to their respective load.
  • the third clutch is independent of the other couplings switchable and can be dimensioned according to their load.
  • the third clutch is independent of the other couplings switchable and can be dimensioned according to their load.
  • the third clutch is dimensioned such that it can absorb the high alternating torques in stationary operation directly between the main drive shaft and additional flywheel.
  • the other clutches can thereby smaller and therefore less expensive dimensioned become.
  • it is advantageous for reasons of mechanical reliability, to initiate the high alternating torques occurring while avoiding intermediate links in the main drive shaft or in the additional flywheel.
  • only the additional flywheel is accelerated by the operatively connected main engine to a speed when starting the weaving machine first in the switching state a, which corresponds to at least almost one operating speed.
  • the main engine is at least almost decelerated to standstill in the switching state d and the main motor is operatively connected to the main drive shaft to the switching state b.
  • the weaving machine is accelerated at least almost to the operating speed via the main drive shaft and finally by transition to the switching state c, the main motor again operatively connected to the previously accelerated additional flywheel while it remains operatively connected to the main drive shaft.
  • additional flywheel causes a speed stabilization to compensate for changing torques in further operation.
  • the main drive shaft and acting as a speed stabilizer additional flywheel are either directly operatively connected to each other or operatively connected to each other via the two clutches and the main engine.
  • the components to be connected at least almost rotate with the same speed.
  • a speed is set for it which is above the operating speed.
  • According to a further aspect of the invention is for braking and stopping the weaving machine from stationary operation in which the switching state c or e is present, first by uncoupling the additional flywheel, the switching state b brought about and the main drive shaft is braked by the main motor until at least near standstill ,
  • the main motor can slow down the loom to a standstill within a much smaller angular range in this way, as is possible in arrangements in which the weaving machine and the associated with relatively high kinetic energy flywheel is braked.
  • the switching state d is preferably set, wherein the main drive shaft is uncoupled from the main engine and brought into operative connection with a machine-fixed component.
  • This measure serves for the safety of the operator of the weaving machine, which are thereby protected against unexpected movements of the weaving machine parts during standstill phases and on the other to ensure reproducible subsequent operations by the weaving machine is held at a defined rotation angle and restarted from there.
  • the inventive method corresponds to a method with a so-called direct drive, the mass in start and stop phases, ie without the uncoupled Flywheel, and mass-laden in stationary operation, ie operated with coupled flywheel.
  • a drive arrangement of a weaving machine which comprises a main motor, a main drive shaft drivable by the main motor and arranged coaxially with the rotor shaft of the main motor, and an additional flywheel drivable by the main motor.
  • the coupling means On the rotor shaft of the main motor at least one coupling means is arranged rotationally fixed.
  • the coupling means is rotatably connected via a first driver element with the main drive shaft and also rotatably connected via a second driver element with the additional flywheel.
  • the coupling agent may be an integral part of the rotor shaft, e.g. a toothing or coupling jaws arranged on the rotor shaft.
  • the first and / or the second driver element may be an integral part of the main drive shaft and the additional flywheel.
  • the alternating torques are derived in stationary weaving from the main drive shaft indirectly to the additional flywheel, namely via the first driver element, the coupling means and the second driver element.
  • a preferred embodiment of the invention provides that the main drive shaft via a switchable coupling directly to the additional flywheel is rotatably connected. With such an arrangement, it is possible to derive the high alternating torques in the stationary weaving from the main drive shaft directly to the additional flywheel mass or to compensate for the additional flywheel, without burdening the other drive elements.
  • the first driver element is designed and arranged such that the main drive shaft is rotatably connected either with the coupling means or with a machine-fixed component of the loom.
  • the dual function of the first driver additionally creates a holding brake for the main drive shaft of the loom.
  • the coupling means is preferably a coaxially arranged on the rotor shaft of the main motor clutch disc and the first and the second driver element are formed as armature discs, wherein both armature discs are arranged coaxially to the clutch disc and frictionally connected to the clutch disc.
  • the first designed as an anchor plate and arranged coaxially with the clutch disc driver element is selectively rotatably connected to the clutch disc or with a machine-fixed part of the loom.
  • the rotationally fixed connection can be designed either frictionally or positively.
  • the drive arrangement with the third clutch also allows operation in a switching state in which the main motor is coupled to the additional flywheel and at the same time to the main drive shaft and the additional flywheel is also coupled directly to the main drive shaft.
  • the present invention further includes a weaving machine characterized by one of the aforementioned drive arrangements.
