Definitions

  • the invention relates to a device for the continuous production and laying out of yarn loops to form a belt with a yarn feed, a rotating laying device and a belt conveyor for the removal of the loop belt.
  • Devices of this type are used in the continuous treatment of yarns and form, for example, preliminary stages to stabilizing devices such as steaming chambers.
  • a known device of this type is known from German Offenlegungsschrift No. 3 114 535.
  • yarn is applied from a revolving winding wing to a winding body and transferred from this to a belt conveyor.
  • the axis of the winding body is perpendicular to the axis of rotation of the winding wing and to the direction of travel of the belt conveyor.
  • the winding body itself is formed from two circular disks, which are arranged at a distance on this axis. On the circumference of these discs there are adhesive surfaces to which the yarn is applied by means of the winding wing.
  • the winding body is rotated about its axis, and at the same time the winding wing rotates around the winding body.
  • the yarn, which is carried by the winding wing is continuously placed loop by loop on the jacket of the winding body.
  • these loops are turned by about 90 ° and then placed on the belt conveyor by a stripping device.
  • a continuous long band of loops of thread forms on this.
  • the loops produced first are at the front and top of this loop band.
  • the end of the yarn must be held until so many loops have formed on the winding body that they clamp each other on the winding body.
  • This holding of the beginning of the yarn is usually done by hand, which leads to considerable difficulties in machines with several such devices arranged side by side. It is also possible to clamp the beginning of the yarn by mechanical means and to loosen it after some time, but this makes the construction of the machine complex and prone to failure. It also proves disadvantageous that the yarn is put under tension and stretched by the winding process on the winding body.
  • the device according to the invention has a simple and reliable construction.
  • the yarn is brought to the rotating disc with the aid of the yarn introduction device and, if necessary, compressed air.
  • the yarn enters the disk from below through the outlet opening on the periphery of the disk and is laid out in loops on the disk surface.
  • the transport surface which is arranged above the disc, moves the loops away from the disc at a constant speed, and a continuous loop belt is formed.
  • the newly created loops are repeatedly placed on the belt from below, which means that the beginning of the belt always remains at the top.
  • the yarn can thus be pulled upwards without difficulty, and there are no tangles in the yarn or other disturbances.
  • the yarn On the surface of the rotating disc, the yarn is laid out in loops without tension, since no additional devices for clamping and tightening the yarn are necessary.
  • the transport surface Starting at the start of laying out the loops is made possible by the static friction between the transport surface and the yarn, the transport surface being arranged at a distance from the surface of the rotating disk and the base plate. This distance depends on the thickness of the yarn and the displacement of the individual loops in the pull-out direction.
  • Another advantage of this device is that it can automatically adapt to changes in the yarn thickness and displacements of the individual loops. In the event of yarn interruptions or other malfunctions, the device can be easily removed from stuck yarn parts, since the yarn is introduced straight into the loop-laying device and is not wrapped around any parts.
  • the movable transport surface can be easily lifted off the sling belt so that it is also easily accessible. As a result of the completely automatic start-up and the simple operation of this device, it can be easily installed in continuous working lines and considerably simplifies the operation of the same.
  • the device shown in Figures 1 and 2 consists of a fixed base plate 1, a rotating disc 2, which forms the laying device, a device 6 and a belt conveyor 12.
  • a drive unit 13 Below the base plate 1 there is a drive unit 13 and a bearing housing 14 and a yarn feed 15 with a yarn drive 16 and an air supply 17.
  • the rotating disc 2 is rotatable about the axis 18 and in a circular recess 19 of the base plate 1 and connected to a drive shaft 20.
  • This drive shaft 20 is coupled to the drive unit 13.
  • the drive unit 13 is in turn attached to the bearing housing 14, at the upper end of which a brake and clutch unit 21 is arranged.
  • the drive shaft 20 has in its lower part a bore 22 which merges into a likewise hollow intermediate piece 23 in the upper region.
  • This intermediate piece 23 is of helical design and opens on the lower side 24 of the disc 2 into a channel 25 which penetrates the disc and exits in its outer region 26 on the upper side 27. Bore 22, intermediate piece 23 and the channel 25 in the disk 2 form part of the game feed 15.
  • the device 6 consists of a circulating belt 7, which is guided by two rollers 8 and 9. The entire device 6 is pivotable about the axis 10 relative to the base plate 1.
  • a drive wheel 30 is also arranged on the roller 9 or around the axis 10 and is connected to an intermediate wheel 32 via a toothed belt 31.
  • This intermediate wheel 32 is in turn driven by a drive wheel 33 on the roller 34 of the belt conveyor 12.
  • This connection ensures that the belt 35 of the belt conveyor 12 and the belt 7 of the device 6 run at exactly the same speed. Furthermore, it is also ensured that the parts of the belts 7 and 35 directed against the fixed base plate 1 run in the direction of the arrows 29 and 36 respectively, i.e. in the same direction.
  • the lower band part 11 of the band 7 of the device 6 directed against the base plate 1 forms with its surface the transport surface 3.
  • This transport surface 3 conveys the loops of thread formed by the rotating disc 2 in the direction of the edge 37 of the base plate 1 and transfers them there to the in Belt 35 of belt conveyor 12 running in the same direction so that loops of thread can form between base plate 1 and rotating disc 2 on the one hand and transport surface 3 on device 6 on the other hand, this transport surface 3 can be pivoted with device 6 relative to rotating disc 2 and base plate 1 .
  • the twine loops are formed in a space 28 above the rotating disc 2 and laid out with the aid of the transport surface 3 to the band 5 of twine loops.
  • the yarn 4 is fed to the device, for example, from a preceding device, not shown, on which strands are stretched.
  • the yarn 4 is introduced into the yarn drive 16 via guide rollers, also not shown, a tensioning device and further guide rollers.
  • the yarn drive 16 conveys the yarn 4 into the guide tube 38 and via the deflection roller 39 into the air nozzle 40. This now blows the yarn 4 tension-free through the bore 22 in the interior of the drive shaft 20 and through the intermediate piece 23 into the channel 25 in the Disc 2.
  • the yarn 4 exits through a hole in the outer region 26. Since the disc 2 and thus the hole rotates about the axis 18, the yarn 4 is placed in a circle on the transport surface 3 on the lower part 11 of the belt 7.
  • the band 5 consisting of yarn loops, is continuously formed and laid out.
  • the rotating disc 2 By means of the rotating disc 2, new loops of yarn 4 are continuously formed and attached to the band 5 from below.
  • the beginning of the yarn on the belt 5 is always on top, and the yarn 4 can therefore be drawn off without disturbances after passing through the steaming station, not shown.
  • the device 6 Depending on the thickness of the yarn 4, the device 6 is more or less lifted off the base plate.
  • This setting of the intermediate space 28 takes place automatically, since the device 6 can be pivoted easily about the axis 10.
  • the belt conveyor 12 begins in the area of the edge 37 of the base plate 1 and takes over the belt 5 from loops of thread there.
  • This belt 5 is guided by belt conveyor 12 through a known post-treatment station, in particular a damping device.
  • the belt 35 of the belt conveyor 12 is driven by a drive device, not shown, which expediently acts directly on the roller 34.
  • the belts 35 and 7 are guided on the rollers 34, or 8 and 9 as slip-free as possible, so that the synchronism of the belts 35 and 7 is ensured. This arrangement ensures that the yarn 4 guided through the device without tension and stretch is also designed to be loops tension and strain-free.
  • the twine loops formed over the rotating disc 2 are designed to be stretch-free in the desired shape and at the desired distance, and the yarn is also not subjected to any additional loads when the belt 5 is being transported.
  • the surface of the base plate 1 is provided with a sliding coating, which ensures that the yarn loops or the belt 5 can be pushed onto the belt conveyor 12 without resistance by means of the transport surface 3.
