Definitions

  • the invention relates to a method for operating a weaving machine with a first drive motor which drives a first element, for example a sley, and with at least one second drive motor which drives a second element, for example a shedding device.
  • the drive motor of a shedding device with the main drive motor that drives the batten, To synchronize, so the drive motor of the shedding device must also perform the non-uniform movement. The result of this is that the drive motor, which is already exposed to a high load, to a shed-forming device and also the shed-forming device are subjected to further loads which are not necessary per se.
  • EP 0893535 A1 the control and regulating device so that can be switched between a hard and a soft control.
  • the hard control which is used during the start of the loom, follows the drive motor of the shedding device with very precise synchronization of the main drive motor.
  • the soft control in which the drive motor of the shedding device may advance or lag the main drive motor with slight deviations from the synchronous operation.
  • a drive motor for the shed forming means in particular a jacquard device, and to provide a further drive motor for all other elements of the loom.
  • the two drive motors are connected to each other via an electronic gearbox.
  • the electronic transmission continuously compares the information from two pickups, namely a pickup detecting the rotation of the main shaft of the weaving machine, and a pickup detecting the rotation of the picking means drive motor, thereby ensuring that the two motors are synchronized.
  • a method of operating a loom according to the preamble of claim 1 and a loom according to the preamble of claim 6 is EP-A-1 065 306 known.
  • the invention has for its object to operate a loom of the type mentioned so that as far as possible no unnecessary loads to overcome for the drive motors of elements.
  • This object is achieved by forming a rotation angle course for an imaginary synchronization shaft of the weaving machine, and synchronizing the elements driven by the drive motors in at least one predetermined rotational angular position to the imaginary synchronization shaft, respectively.
  • the invention is based on the consideration that the elements of a weaving machine do not have to be constantly synchronized with one another exactly during the entire weaving cycle, but that the individual ones have to be synchronized Elements must be in appropriate positions only in certain rotational angle positions. During the rest of the web cycle, they can take positions that are largely independent of each other.
  • the imaginary synchronization wave is the element according to which not only the additional elements such as shedding devices or edge feeders or winders or the like. be aligned, but also the batten. The individual elements including the batten are thus no longer synchronized to a main shaft, but to the imaginary synchronization wave to which the sley is synchronized.
  • the individual elements can therefore perform their movements so that the lowest possible loads for their drive motors and / or for the elements themselves occur, without the course of motion is tuned over 360 ° to the other elements and in particular to the movement of the batten.
  • the invention also offers advantages in particular when starting a weaving machine.
  • a drive motor that drives components of greater mass, for example, the drive motor of the batten can be started earlier than, for example, a drive motor for a shedding device.

  • the drive motor of the shed forming means is independent of the main drive motor, it can operate with optimized conditions.
  • the drive motor of the shed forming means is attached to a frame of the loom and connected via an elastic coupling element with drive elements of the shed forming means.
  • the elastic coupling element is at least useful not to transmit vibrations or vibrations from the shedding means to the other elements of the loom and vice versa.

It is sufficient if they are synchronized with a relatively small tolerance to these rotational angular positions of the imaginary synchronization shaft. In this case, synchronization is generally sufficiently accurate if the deviation from the rotational angular position of the imaginary synchronization shaft is less than 5 °. A tolerance value can be set differently for each weft entry.

In this case, the rotational angle curve can be determined as a function of different types of weft thread to be introduced in succession, of successive warp thread bindings, of the number of warp threads to be moved from bottom to top or from top to bottom or depending on other conditions. In particular, a suitable rotation angle curve for the imaginary synchronization shaft for starting and stopping the loom is set.
