Definitions
- the present invention relates to a fabric draw-off device on a circular weaving machine, in which a plurality of partial shafts are arranged in a circle around a circular reed and a plurality of inner and outer healds each carry a part of the two warp thread groups distributed all around To which the weaving or hiking subject is given an opposing up and down alternating movement via a revolving main shaft, which main shaft drives weaving shooters in a circular manner in a round shaft and the tubular fabric thus formed is drawn off via the fabric take-off device.
- the fabric draw-off via gear means is in direct drive connection with the main shaft of the loom.
- this is first achieved by means of a separate motor which drives at least the take-off rollers and, if appropriate, the fabric bale via gear means, the speed of which can be regulated by a computer via a speed controller which is connected to the main drive of the circular loom via a pulse generator or the like Generation of control pulses proportional to the speed of the circular loom, respectively. the main shaft.
- the computer can be programmed accordingly via its keyboard in order to vary the weft thread density in the finest gradations by changing the sequence of the control impulses in order to additionally change the speed of the motor of the fabric extraction device independently of the speed of the circular weaving machine.
- the computer is additionally in signal connection with weft thread monitoring means in order to promptly readjust the speed of the motor of the fabric pull-off device in the predetermined manner in the event of a weft thread error.
- the wave shed circular loom shown rests in the usual way on a machine base frame 1, on which a circular frame support 2 is supported, which supports the reed 3, the on and off buttons 4 for the machine, the frame parts 5 for the ring holder and, among other things.
- the sub-shafts 6 and 7 carries. 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 6 and inner partial shafts 7.
- 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 Ue b roller 17 for these warp ribbons can be seen. bar.
- These warp threads or warp tapes are divided into two sets of warp threads arranged around them 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 thread bobbin 60 is then guided into this so-called weaving or hiking compartment on a horizontal circular path.
- the shooters 30 are driven by a control disk 33, which is seated in a rotationally fixed manner on the main shaft 8 of the machine and which pushes the pushers with pushing means 33 '.
- the main shaft 8 is connected to a drive motor 51 via transmission means 50.
- main shaft 8 here carries two further control disks 26 and 27, which are operatively connected 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 in in a known manner to transfer the shed movements to the partial shafts 6 and 7 respectively.
- 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 tubular fabric can then be pulled off and folded up to form a flat tubular fabric.
- the support 9 for the tissue extraction device 70 is supported on the base frame 1, which, among other things.
- the transmission 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.
- a separate motor which drives at least the take-off rollers 11, 12 and, if appropriate, the fabric bale 13 via gear means 10, the speed of which can be regulated by a computer 62 via a speed controller 61, which is controlled by a pulse generator 63 o.
- the like is connected to the main drive 51.8 of the circular loom to generate control pulses proportional to the speed of the circular loom or. the main shaft 8.
- the computer 62 can be programmed accordingly via its keyboard 64 in order to vary the weft thread density in the finest gradations by changing the sequence of the control impulses in order to additionally change the speed of the motor 60 of the fabric draw-off device independently of the speed of the circular loom. """" 96/12838
- This effect can also be used in order 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 both for the sack edge and also form reinforcements for the bag bottom.
- the computer 62 is still in signal connection 65 with weft monitoring means 66, which are not explained in more detail here, in order to promptly readjust the speed of the motor 60 of the fabric take-off device in the event of a weft error, which ensures a constant weft density, even if through a thread break suddenly drops a weft.
- the computer can reduce the speed at the fabric take-off by half, with six shooters by a third, with eight shooters by a quarter and with ten shooters by a fifth, which allows that due to the delay in the advance of the fabric take-off, the remaining intact weft threads are sufficient to obtain the predetermined weft thread density. It is advantageous here that the arrangement according to the invention can be connected directly to a data processing system via corresponding interfaces on the computer in order to monitor the entire operating situation on the loom and also to be able to control a plurality of such circular looms at the same time.
