Definitions

  • the invention relates to a sliver feed device for an OE spinning machine, with a feed cylinder and a feed trough that can be adjusted against the feed cylinder, the feed trough having lateral webs that guide the sliver in the region of the clamping line.
  • fiber sliver dissolving units such as those used in OE spinning machines
  • a cylindrical, preferably corrugated feed cylinder which forms a clamping point with an associated feed trough
  • the fiber sliver temporarily stored in spinning cans first passes through a compressor on its way to the opening roller, which not only compresses the fiber sliver, but also gives it a specific profile that is favorable for drawing in. This ensures that the sliver with a desired cross section runs into the clamping point formed by the feed cylinder and feed trough.
  • the clamping area formed by the feed cylinder and the feed trough is usually substantially wider than the sliver, so that it is ensured that the sliver, which is pressed into the width by the clamping, is also securely clamped in the edge areas.
  • a fiber beard support with lateral webs after the clamping area. In this way, an uncontrolled divergence of the sliver is to be prevented.
  • Such a fiber beard support which guides the sliver laterally, is described in DE 41 01 315 A.
  • Japanese utility model 44-25154 shows a feed trough with side guide strips, between which a roll-like sliver propulsion element rotates.
  • the invention is based on the object of avoiding the disadvantages of the known devices and of further improving sliver feed device.
  • a corrugation is arranged on the top of the transport collar, which ridges the edge areas of the surface.
  • the corrugation consists of a multiplicity of individual grooves which are arranged orthogonally to the transport direction of the sliver.
  • the bottom of the groove is concave at least in its outlet zones.
  • the grooves are arranged on the circumference of the transport collar with an angular distance ⁇ of 3 ° to 15 °, preferably 6 ° to 7 °.
  • the cleaning devices in the region of the end faces of the transport collar of the feed cylinder are preferably designed as spirally arranged transport grooves.
  • the spiral direction of these transport grooves is selected such that they result in a transport component in the direction of the surface of the transport bundle when the feed cylinder rotates in the direction of the sliver transport. In this way it is ensured that fibers or impurities which could enter this area due to the play predetermined between the transport bundle and the food tray webs are immediately removed again in the direction of the transport bundle surface.
  • the lateral webs of the feed trough have bevels which are directed inwards, that is to say, towards one another.
  • the width of these chamfers is chosen so that they are wider than the amount of axial play of the food tray on the corresponding bearing axis.
  • the sliver inlet surface is either flat or has a concave curvature in the area of the clamping point.
  • the radius of the curvature is somewhat larger than the radius of the engaging conveyor belt.
  • the opening unit 1 shown schematically in FIG. 1 has, as usual, an opening roller 3 rotating in an opening roller housing 2.
  • Such opening rollers have a sawtooth or needle set (not shown) for releasing individual fibers from the sliver 9 provided.
  • the sliver 9 temporarily stored in (not shown) sliver cans is continuously fed to the opening roller 3 by means of a sliver feed device 4.
  • the sliver feed device 4 consists of a feed cylinder 5 rotating in the ER direction and a feed trough 7 which can be set against the feed cylinder 5.
  • the feed trough 7 is fixed to a pivotably mounted feed table 6 by means of a fastening means 10 and can be pivoted together with the latter about a bearing axis 15.
  • the feed table 6 is acted upon by a spring element 11 in the direction of the feed cylinder 5.
  • a sliver compactor 8 is integrated in the feed table 6, which guides the incoming sliver 9 to a clamping line formed between the feed cylinder 5 and the feed trough 7.
  • the feed cylinder 5 has a stepped transport collar 16 which has a corrugation 27 on its surface 17.
  • This corrugation 27 consists of a plurality of grooves 20 arranged orthogonally to the transport direction, which are embedded in the surface at an angular distance of ⁇ 3 ° to 15 °, preferably 6 ° to 7 °.
  • the grooves 20 already end at a distance from the outer end faces 18, 19 of the transport collar 16.
  • the groove base 28 is concave at least in the outlet zones.
  • the end faces 18, 19 of the transport collar 16 are each equipped with a cleaning device 21 which is designed as a spirally arranged transport groove 26.
  • the width B1 of the transport collar 16 is chosen so that it is Game B3 can circulate between the webs 24 of the U-shaped feed trough 7.
  • the feed trough 7 is connected via fastening means 10 to a feed table 6 which is pivotable and arranged with axial play D2 on a bearing axis 15 and is locked there by a fastening means 23.
  • the outer webs 24 of the feed trough 7 are equipped with insertion bevels 22 which have a width D1.
  • the lead-in bevels 22 face inwards, that is to say they face each other.
  • the feed trough 7 either has a flat sliver inlet surface 25 (FIG. 3) or, as indicated in FIG. 4, the sliver inlet surface 29 is concave in the area of the feed cylinder 5.
  • the radius of the trough is slightly larger than the radius of the transport collar 16 of the feed cylinder, so that the clamping line between the feed cylinder and the feed trough can be moved by moving the feed trough in the horizontal plane.
  • the sliver feed device according to the invention is a functional, easy-to-use device which ensures that the opening roller is continuously presented with a carefully treated, evenly clamped sliver during the spinning process.
