Definitions
- the present invention relates to a device for monitoring the weft threads on a circular loom, which are unwound from the respective bobbin of the weaving guards running in the shed along a circular path formed by the round reed and are delivered to the fabric edge of the tubular fabric produced, scanning means monitoring the respective weft thread. in order to generate an electrical control signal in the event of a weft thread error.
- Circular weaving machines are generally known, in which a plurality of partial shafts are arranged in a circle around the round reed of the machine and a plurality of inner ones and outer healds for guiding a part of each of the • two warp thread groups distributed all around, which are given an opposing upward and downward alternating movement to form the weaving or traveling shed via the rotating main shaft.
- the weavers who are driven in rotation by the main shaft in the round shaft continuously feed the weft thread to be drawn off from the relevant bobbin into the traveling shed.
- the tubular fabric produced in this way is then pulled off and wound up flat.
- the electrical control signal can be generated by a magnetic sensor arranged in the area of the orbit of the shooters, which cooperates with a permanent magnet carried by the respective shooter, the permanent magnet being on a weft thread that has been pulled off pivoted lever deflected against the action of spring-like restoring means and is held outside the operative connection with the magnetic sensor, in order to generate an operative connection of the permanent magnet with the magnetic sensor in the event of a weft fault under the action of the restoring means of an active control signal producing end position.
- Such a device is not subject to the effects of extraneous light or disturbances due to dusting or any wear.
- This facility also allows the Working of reflex tapes, works safely at any shooting speed and has a very high sensitivity and speed.
- a simple and absolutely functionally reliable construction can also be achieved in that the swivel lever carrying the permanent magnet at its free end is arranged with its swivel axis on the thread insert of the shooter and is under the action of a return spring, the drawn weft thread having an end region on the free Penetrates end of the pivot lever or at least partially wraps around it, or that the pivot lever carrying the permanent magnet at its free end is arranged with its pivot axis on the axis of rotation of the weft bobbin and is under the action of a return spring, with the weft thread being pulled off an end region at the free end of the pivot lever penetrates or at least partially wraps around.
- a return spring the drawn weft thread having an end region on the free Penetrates end of the pivot lever or at least partially wraps around it
- the pivot lever carrying the permanent magnet at its free end is arranged with its pivot axis on the axis of rotation of the weft bobbin and is under the action of a return spring,
- FIG. 1 is a side view and a schematic representation of a circular loom
- Fig. 4 shows a variant of the arrangement according to
- a machine base frame 1 on which a circular frame support 2 is supported, which supports a round reed 3, a on / off switch 4 for the machine and further frame parts 5 for the Support of shafts 6 carries.
- These shafts 6 are arranged in a known manner in a circle around the main shaft 8 of the machine and essentially form the compartment-forming means of the machine.
- the support 9 for the base frame 1 is supported Fabric take-off device, which is only indicated here by fabric take-off rollers 10.
- a fabric spreader 14 is also effective in the trigger area.
- the feed roller 15 for the warp threads on the left and the feed roller 16 for the warp threads on the right are visible on the circular loom shown.
- warp threads 7 are divided into two sets of warp threads arranged all around and are drawn off in a known manner from groups of warp thread spools, not shown in any more detail.
- one of these coulters is then raised, while the other is guided downwards from the height of the weaving plane by the so-called shed changing movement, so that an upper warp thread pocket 7 'and a lower warp thread pocket 7 "(FIGS. 2 and 4) are created.
- this so-called weaving or traveling compartment at least one shooter 30, but usually several, then runs on a horizontal circular path with a weft bobbin 31 (FIG. 4) unwound weft thread 32 (FIGS.
- the electrical control signal 23 can be generated by a magnetic sensor 22 which is arranged in the region of the orbit of the shooters 30 and which interacts with a permanent magnet 24 carried by the respective shooter 30.
- the permanent magnet is arranged on a pivot lever 26 deflected by the drawn-off weft thread 32 against the action of spring-like restoring means 25 and is held outside the operative connection with the magnetic sensor, so that in the event of a weft thread failure under the action of the restoring means 25, it is in an operative connection of the permanent magnet with the magnetic sensor to produce an active control signal 23 producing the end position.
- a plurality of magnetic sensors 22 in the area of the orbital shooter's orbit, preferably on reed 3, as indicated in FIG. 1.
- the pivot lever 26 carrying the permanent magnet 24 at its free end is arranged with its pivot axis 27 on the thread insert 30 'of the shooter 30 and is under the action of a return spring 25, wherein the drawn weft thread penetrates an end region at the free end of the pivot lever 26 or at least partially wraps around it.
- the pivot lever 26 'carrying the permanent magnet 24' at its free end can be arranged with its pivot axis 27 'on the axis of rotation of the weft thread bobbin 31 and act under the action of a return spring 25', the drawn weft thread also having an end region here penetrates at the free end of the pivot lever 26 'or at least partially wraps around it.
