  • the invention relates to a device for winding a knitted fabric web, delivered from a warp knitting machine to a wrap is, using an axle drive, which means the goods tension measuring sensor is regulated with regard to its speed.
  • a device for winding a knitted fabric web, delivered from a warp knitting machine to a wrap is, using an axle drive, which means the goods tension measuring sensor is regulated with regard to its speed.
  • Such a device is known from DE 22 19 207 A.
  • Such a device is also in the draft for an ISO standard 864-2 / 07.94, Page 12 shown in section 6.1.2.
  • the final drive takes place here by means of of an electric motor, which uses a dancer roller that acts on the voltage the winding web reacts, and one from the dancer roller influenced controller is controlled in terms of its speed so that the Goods tension is kept constant. This means with the same Working speed of an upstream warp knitting machine that with increasing diameter of the goods roll according to its speed is turned down.
  • the invention has for its object to design the device so that it can be easily wound up with elastic knitwear. According to the invention this happens by the features of claim 1 and in particular in that a distance from the wrap held, the run-up point of the web on the goods roll Scraper roller is arranged, whereby to maintain a substantially constant distance between the goods roll and the stripping roller Relative displacement takes place along a radial guide.
  • the device can be designed so that to comply with the essential constant distance between goods roll and stripping roller the latter radially increases with increasing diameter of the material roll is led outside. But it is also possible to increase the amount of goods Lead the diameter away from the stripping roller. In both cases there is a relative displacement of the goods roll relative to the stripping roller before, along a radial guide, so that regardless of respective diameter of the goods roll the stripping roller close to the Contact point of the web is held on the wrap, so that the above-mentioned short path from the transition from the stripping roller to Goods wrapping results.
  • the stripping roller is appropriately stored on the ends of swivel arms, whose position is chosen so that at the pivoting of the stripping roller an approximately straight radial movement in relation to the winding of goods.
  • the stripping roller guides a movement along an arc, but with sufficient Length of the swivel arms deviates from the straight line so little that this for the desired position of the stripping roller in the same Distance to the wrap is practically irrelevant. Compliance with the The distance between the stripping roller takes place in a known manner by means of a Distance sensor, e.g. based on a reflection of a sound beam or a light beam.
  • the axis of the Expediently on a longitudinal guide directed perpendicular to it, so that the axis of the goods roll increases with it Diameter constantly removed from the stripping roller, but this is the condition it is observed that the distance between the goods winding and Stripping roller is kept substantially the same. In this case too compliance with the distance between the goods roll and the stripping roller brought about by means of a known distance sensor.
  • the stripping roller is conveniently deflection rollers for the web upstream, which relax the web via a multiple deflection.
  • Under the influence of elastic threads knitted into the knitted fabric there is a strong inner tension immediately after the knitting process in the elastic knitted fabric, which this transversely on its way to Shrink wrap in the transverse direction.
  • the knitwear retains its considerable internal tension, especially in the transverse direction, which occurs when Winding up the web on the goods roll in unevenness of the Winding up can affect.
  • the stripping roller is in the usual known manner with the roller provided in the manner of a coil spring circumferential bead, namely on both sides with the opposite slope, so that with a corresponding Direction of rotation of the stripping roller results in the beads spreading apart, who press on the web and strip it out accordingly.
  • the stripping roller is given expediently a peripheral speed that at least that is ten times the transport speed of the web, so that the Scraper roller during the transport of the web with considerable Relative speed exceeds.
  • the knitted fabric web 1 (drawn in dashed lines) is one Known, not shown warp knitting machine delivered and wrapped around first the three take-off rolls 2, 3 and 4, which are due to tight wrapping with their speed of the web 1 the desired transport speed give.
  • the web 1 then runs around the three deflection rollers 5, 6 and 7, of which the roller 7 is designed as a dancer roller is.
  • the deflection / dancer roller 7 is mounted on the swivel arm 8, which around the axis 9 is rotatably arranged.
  • the axis 9 forms with their storage 10 a known angle indicator, not shown in detail, which in Depending on the angle of rotation of the swivel arm 8 a corresponding Signal transmitted via line 11 to the controller 12, the in a known manner with a controlled variable, the drive motor 13 for the Goods roll 14 influenced, which will be discussed in more detail below.
  • the deflection / dancer roller 7 acts on the web 1 with its weight a, the respective tension of the roller 7 more or less opposite the position shown in Figure 1 raises or lowers what by arrows passed through the roller 7 are indicated.
  • the swivel arm 8 can also be loaded with an adjustable spring in order to to be able to set the desired tension of the web. in the If the roller 7 is pivoted upwards, this means a Increase in tension in the web 1 caused by a slowdown of the drive motor 13 is answered and vice versa.
  • a known control mechanism is a known control mechanism.
  • the web 1 is guided from the roller 7 to the stripping roller 15, which in the manner described above by their relatively high speed and their jacket structure ensures that the web 1 on the surface the stripping roller 15 is laterally stripped, whereby the web 1 this position assumes its position, which is only under low transverse stress.
  • the stripping roller 15 is held close to the run-up point 16, specifically with the distance A, so that the rotation of the stripping roller 15 does not can directly affect the winding 14.
  • the stripping roller 15 is mounted on the swivel arms 17, of which only one is shown and which are arranged rotatably about the axis 18. With the swivel arms 17, the worm wheel 19 is connected, which via the Auger 20 is driven by the motor 21. By an appropriate Rotation of the screw 20 under the influence of the motor 21 results a respective pivot position of the pivot arms 17 and thus the position of the stripping roller 15 with respect to the surface of the goods roll 14, with which the distance A is kept constant.
  • the distance A between the stripping roller 15 and the surface of the Goods roll 14 is set as follows: With the concerned At the end of one swivel arm 17, the distance sensor 22 is firmly connected, which is, for example, an ultrasound transmitter and receiver acts in a known manner depending on the distance between the Sensor 22 and the surface of the goods roll 14 constantly signals whether the sensor 22 and thus the stripping roller 15 a certain desired Keeps distance from the surface of the goods roll 14. If exceeded or falling below the distance A, the sensor 22 transmits the line 23 a corresponding signal to the controller 24, depending on the sign of this signal the motor 21 to a corresponding one Twisting caused either in the left or right direction and thus the Swivel arm 17 adjusts so that the stripping roller 15 in the desired distance A from the surface of the goods roll 14. This is also a known control mechanism.
