Definitions

  • the present invention relates to a drive device on a circular weaving machine, in which a plurality of partial healds are arranged in a circle around a circular reed and each carry a plurality of inner and outer healds for guiding a part of each of the two warp thread groups distributed all around, which form the weaving or traveling shed
  • An opposing upward and downward alternating movement is issued via a revolving main shaft, which drives the revolver in a circular manner via a camshaft shuttle in the rotary shaft and the tubular fabric thus formed is drawn off via a fabric extraction device, which is driven by the main shaft motor, which is triggered by a signal from weft monitoring means can be switched off from its circuit.
  • Circular looms 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 carry 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 by the main shaft in the rotary shaft continuously feed the weft thread to be drawn off from the relevant bobbin into the traveling compartment.
  • the tubular fabric produced in this way is then pulled off and wound up flat.
  • a significant disadvantage with such circular looms are the thin spots in the fabric after a weft defect, for example due to exhaustion of the weft bobbin of one or the other rotating shooter or as a result of weft breaks.
  • the usual weft monitoring means on the reed of the machine are able to immediately transmit a stop signal to the motor of the machine driving the main shaft of the circular loom and on the other hand the fabric pulling device, which then does not stop abruptly, but under the Effect of the large mass forces acting on the main shaft continues to rotate.
  • the drive device can be further configured such that the clutch is followed by an electromagnetic brake which can be actuated by a stop pulse which is synchronous with the stop signal of the weft thread monitoring means.
  • the drive device now allows a configuration in such a way that weft densifications that form transverse stripes form periodically and at a predetermined distance in a simple manner, at which points a separation of the fabric web can subsequently be carried out, the weft densifications being used, for example, for the production of sacks both for the sack edge and also form reinforcements for the bag bottom.
  • L and 2 rests in the usual way on a machine base frame 1, on which a circular frame support 2 is supported, which the reed 3, the on and off button 4 for the machine, the frame parts 5 for the Ring holder and others also carries the partial shafts 6 and 7.
  • These partial shafts 6 and 7 are arranged in a circle in two rows around the main shaft 8 of the machine, these forming outer partial shafts 6 and inner partial shafts 7.
  • the support 9 for the tissue extraction device 70 is supported on the base frame 1, which, among other things.
  • the gear means 10 for the fabric take-off further comprises fabric take-off rollers 11 and 12 and the fabric bale 13.
  • a fabric spreader 14 is also effective in the trigger area.
  • the feed roller 15 for the warp threads or tapes not shown in detail on the left and the feed roller 16 for the warp threads on the right and also the overflow rollers 17 for these warp ribbons are visible on the weaving machine shown.
  • These warp threads or warp ribbons 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.
  • To form the shed one of these shares is then raised by the partial shafts, while the other is guided downwards from the height of the weaving plane by the so-called shed changing movements, so that an upper warp thread compartment and a lower warp thread compartment are created.
  • At least one, usually several shooters 30 with a weft bobbin 60 is then guided into this so-called weaving or hiking compartment on a horizontal circular path. Due to the circular movement of the shooters, the weft thread unwound from the weft bobbin is delivered to the fabric edge of the tubular fabric produced, so that this weft thread can be woven into the fabric. The hose The fabric can then be pulled up and folded together to form a flat tubular fabric.
  • the drive of the shuttles 30 is effected by a control disc 33 which rotatably on the main shaft 8 of the machine M a-rests and which engages with sliding thrust means of the contactors.
  • the main shaft 8 is connected to a drive motor 51 via transmission means 50.
  • this motor 51 is also connected to the drive 10 of the tissue extraction device 70.
  • main shaft 8 here carries two further control disks 26 and 27, which are in operative connection via a plurality of pivot levers 36 and 37 arranged radially around these control disks with so-called shaft rods 46 and 47, which shaft rods 46 and 47 transmit the subject-changing movements in a known manner Transfer partial shafts 6 and 7 respectively.
  • an electromagnetic clutch 52 and preferably an electromagnetic clutch between the drive motor 51, which is connected in a conventional manner to weft monitoring means 55, which are not mentioned here in order to be disconnected from its circuit in the event of a weft error, and the transmission means 10 of the fabric pull-off device 70 Brake 53 arranged.
  • Both this electromagnetic clutch 52 and the brake 53 can be activated by a stop pulse which is synchronous with the stop signal of the weft thread monitoring means 55.
  • clutch 52 and brake 53 are connected directly to weft monitoring means 55 via control line 57.
  • This effect can now also be used to carry out weft compaction on the fabric periodically and at a predetermined distance in a simple manner, at which points a separation of the fabric web is subsequently carried out, the weft compaction then being used, for example, for the production of sacks for both the sack edge as well as reinforcements for the bag bottom.
  • the electromagnetic clutch 52 and optionally the brake 53 can be actuated by a stutter circuit 56 or the like, independently of the stop pulse of the weft monitoring means 55, according to FIG. 1.
  • Such stutter circuits or the like are known Programmable devices for generating periodic or aperiodic electrical switching pulses and therefore do not need to be explained in more detail here. Conventional devices can also be used as an electromagnetic clutch and brake.
