Definitions

  • the invention relates to a weft selection device for a weaving machine with weft supply bobbins arranged outside the shed, with a number of thread feeders each intended for guiding a weft thread, each optionally via a drive part, which is driven in an oscillating manner by means of an associated actuating device with an oscillating rhythm of the weft insertion frequency
  • Carrier can be coupled and decoupled from it, can be locked and adjusted between a ready position and a transfer position there and back, wherein in the transfer position the respective weft thread is presented to a weft insertion member that can be inserted into the shed for a subsequent weft insertion.
  • each thread feeder is moved back from the transfer position to the ready position after the thread transfer to the weft insertion member and is kept ready in this position for a further weft insertion, for which the weft thread guided by the thread feeder concerned is presented to the weft insertion member should.
  • the thread feeders are each articulated to a fixedly mounted swing arm, which can be coupled to an electromagnet via a magnet armature arranged on it, which is mounted on a carrier carrier which vibrates in a rhythmic manner with the weft insertion frequency is arranged.
  • the driver carrier can be pivoted via a cam drive between a rest position corresponding to the ready position of the thread feeder and a working position corresponding to the transfer position of the thread feeder and has a crossbar which carries all the electromagnets assigned to the swing arms.
  • one of the swing arms is coupled to the driver carrier via the assigned, excited electromagnet and, together with the associated thread feeder, is led from the ready position to the transfer position.
  • the thread feeder After each weft insertion, the thread feeder is returned from the transfer position against the ready position, even if the same weft thread is also intended for the immediately following weft thread insertion and the thread feeder in question for this or any further immediately following weft insertion from the standby position just reached is moved to the transfer position. Due to the unnecessary return and forward movements of the thread feeder and the corresponding deflection and feed movements of the weft thread, the interacting parts of the weft thread selection device and the weft threads are unnecessarily stressed, in particular a disadvantageous reduction in the operationally predetermined tension of the weft thread can move back and forth between a stretched position and a deflected position.
  • the invention has for its object to provide a weft thread selection device which is improved in this regard in particular and which allows the number of adjustment movements of the thread feeder and the drive parts interacting therewith to be limited to a minimum determined in each case solely by the predetermined program of the weft thread sequence and thus a corresponding one Reduction of the stress on the interacting parts of the device and, compared to previous versions, a correspondingly quieter, gentler guiding of the weft threads is ensured.
  • the drive part is coupled to an actuating element of the actuating device via a fixedly mounted guide part which can be moved back and forth against the movement area of the driver and has a stop part which can be engaged in the movement area of the driver when the actuating device is active and can be disengaged when the actuator is passive , and that the drive part is assigned a blocking element that can be controlled via the adjusting device, which can be adjusted between a release position that can be taken with a passive adjusting device and permits relative movements of the drive part and a blocking position that can be taken with an active adjusting device, and via which the drive part in a working position corresponding to the transfer position of the thread feeder active actuator can be blocked.
  • the design of the weft thread selection device permits a temporary decoupling of the thread feeder in the transfer position and the drive parts interacting therewith from the driver that is inevitably driven at the rate of the weft insertion frequency, provided that the adjusting device assigned to the thread feeder concerned - corresponding to the respective weft thread selection program - for the Weft insertion of the same weft thread remains activated in the following weaving cycle. If a different weft thread is provided for the weft insertion for the following weaving cycle, the blocking element is released by the blocking element which is appropriately moved into the release position in the case of a passive adjusting device and is returned to a rest position corresponding to the ready position of the thread feeder.
  • each of the thread feeders is assigned a locking hook connected to a control magnet, by means of which one end of a pivotable drive lever connected to the thread feeder is held when the magnet is excited .
  • a pivotable drive lever connected to the thread feeder is held when the magnet is excited .
  • the drive levers which can optionally be articulated on the locking hook, the thread feeders are also returned from the transfer position to the ready position after each thread transfer in this arrangement. A blocking of the thread feeder in the transfer position is not provided for in this known device and is also not possible.
  • the embodiment according to claim 7 allows the use of actuating devices with small actuating forces, since these actuating devices are only provided for the transmission of the switching information to the actuating device, while the blocking and releasing of the drive part connected to the relevant thread feeder takes place in each case via the actuating device coupled to the machine drive .
  • the embodiment according to claim 9 allows, within certain design limits, an arrangement of the drive, blocking and control parts interacting with the driver that is largely independent of the operational arrangement of the thread feeders.
  • the adjustment of the weaving machine to different weaving widths only requires a corresponding adjustment of the thread feeder, while the drive parts interacting with the driver can remain in their position given by the connection to the machine drive.
  • a weaving shed 2 formed by warp threads 1 and weft threads 3, 3a of a rapier weaving machine 4 are indicated in FIGS. 1 and 2.
