Definitions

  • the invention relates to a fleece funnel on a stretch of the textile industry.
  • the fleece funnel is arranged at the exit of a textile drafting system.
  • the fiber fleece supplied by the pair of delivery rollers is conveyed into the fleece funnel. There, the nonwoven is combined and leaves the nonwoven funnel as a sliver.
  • the sliver is passed directly in a sliver tube to a sliver funnel, which is arranged in front of a pair of calender rolls.
  • the calender rolls convey the tape into a depositing device, which deposits the sliver in the can.
  • GB-A 609 753 shows a sliver compactor as used in front of a pair of calender rolls of a textile drafting system.
  • the replaceable nozzle of a compressor shown there, the cross-section of an incoming fiber sliver is tapered.
  • a corresponding nozzle insert can be used in the funnel mouth of the compressor.
  • the compressor with a circular funnel opening and a convex funnel wall is not suitable for collecting a wide fiber fleece before entry into the nozzle opening at the currently usual delivery speeds without problems and advantageously, folding it, deflecting it into the nozzle opening in order to discharge it as sliver.
  • the compressor is a different object with different tasks and characteristics than a fleece funnel.
  • GB-A 21 32 240 also shows a compressor which consists of two individual funnels arranged one behind the other, both of which taper in the direction of passage of the fibers. An annular gap, which forms an air outlet opening, is arranged between the two individual funnels. For reasons already mentioned, this compressor is also not suitable for fulfilling the task of a fleece funnel on a stretch.
  • the fleece funnel of the RSB 851 range meets the requirements for safe and advantageous folding of the fleece and compression of the folded fleece into a sliver.
  • This state of the art is documented in route RSB 851 (4135), SB 851 (4131), operating instructions, August 1990, p. 28, section 4.4.3.2, fig. 7a, 7b and forms the main concept of claim 1.
  • the fleece funnel is made from a solid piece of brass. The manufacturing effort is relatively low.
  • the fleece funnel is designed so that it is more wide than high. It has a cylindrical hole in the middle that acts as a funnel tube.
  • the funnel is adjusted to the middle of the take-off rollers in order to ensure an optimal entry of the fleece into the funnel bore.
  • the adjustment requires different fleece funnels with different funnel bore diameters Adjustment gauges (see RSB 851 (4135), SB 851 (4131) operating instructions, August 1990, p. 28, 4.4.3.2, Fig. 7b).
  • the object of the invention is to reduce the maintenance expenditure caused by wear of the fleece funnel.
  • This object is achieved by the characterizing features of claim 1.
  • the original funnel mouth has been expanded to accommodate the exchangeable, tubular insert.
  • the insert itself has a cylindrical bore that corresponds to the desired diameter for the sliver throughput.
  • the insert can be slid into the funnel mouth to a final position. The end position is reached by a stop in the fleece funnel. The stop is fixed in this end position. In this end position, the insert conforms to the fleece funnel.
  • the insert thus acts as a funnel tube. It is essential that the insert has a cylindrical bore, while it is immaterial how the outer surface of the tubular insert is designed. If there is material wear on the insert, only this insert is changed. When changing the insert, the fleece funnel remains in its adjusted position. This solution is advantageous because the entire fleece funnel does not have to be changed and readjusted after the exchange.
  • the insert is made of low-wear material.
  • the insert consists of solid, wear-resistant material or only its surface is coated with this material.
  • Such low-wear material is stainless steel or ceramic. This measure also increases the wear resistance of the insert and extends its service life.
  • the insert is made of expensive, high-quality material, it becomes more cost-effective to use because the amount of material used is considerably less than if the fleece funnel as a whole consisted of the expensive and high-quality material.
  • a pair of output rollers 7, 70 are arranged. This pair of output rollers 7, 70 conveys the nonwoven fabric into the nonwoven funnel 1. The nonwoven fabric is combined in the nonwoven funnel 1 and transported further through the funnel mouth to the sliver tube 8. The sliver continues in guided a sliver funnel 9. At the exit of the sliver funnel 9, the sliver is gripped by the pair of calender rolls 10, 100 and conveyed on to the laying device of the draw frame.
  • the arrows in FIG. 1 indicate the direction of transport of the textile material.
  • FIG. 2 shows the fleece funnel 1 seen from the direction of the incoming fiber fleece.
  • the fleece funnel 1 is not circular but has an essentially rectangular design.
  • the funnel is delimited by the funnel walls 2, 20, 200.
  • a funnel bore 3 is provided in the center of the fleece funnel 1.
  • This funnel bore 3 is connected to a threaded bore 4 offset by 90 °.
  • This funnel bore 3 is necessary in order to be able to receive the insert 11 according to FIG. 5.
  • the possibility of receiving the insert 11 is an essential aspect. It is irrelevant to the invention whether the funnel bore 3 is cylindrical or has another shape, for example a conical or angular one. The prerequisite is that it can accommodate the tubular insert. In the example, a cylindrical bore 3 was chosen.
  • the fastening bores 5, 6 are provided for fastening the fleece funnel 1 to the route.
  • the funnel bore 3 has a diameter D which corresponds to the outer diameter D A (according to FIG. 5) of the insert 11.
  • This funnel bore 3 is able to receive the insert 11 shown in FIG. 5 in a form-fitting manner.
  • the positive reception of the insert 11 in the fleece funnel 1 is shown in FIG. 6.
  • the insert 11 is positively inserted into the fleece funnel 1 in the end position.
  • the funnel bore 3 has a stop 12.
  • the insert 11 is pushed into the funnel bore 3 during installation, ie in the transport direction of the textile material.
  • the insert 11 is in its end position when it strikes the stop 12 with its protruding edge.
  • the insert 11 is always pressed against the stop 12 by the incoming fleece and at the same time fixed in this position. In order to prevent twisting of the insert 11, twisting of the insert 11 is prevented by screwing a threaded screw into the threaded bore 4.
  • the insert 11 acts as a funnel tube.
  • the threaded screw in the threaded bore 4 is loosened and the insert 11 is pressed out of its end position against the transport direction of the nonwoven fabric.
  • the fleece funnel 1 remains in its originally adjusted position.
  • the interchangeable insert 11 consists of a high-quality, low-wear material, such as stainless steel or ceramic.
  • the insert can also consist of a metal core, the surface of which is coated with low-wear material.
  • the replacement of the insert 11 is necessary if there are signs of wear on its surface.
  • the exchange is time-saving because the entire fleece funnel 1 does not have to be removed and readjusted. With this solution it is also possible to be rational in terms of material costs.
  • the invention also has the advantage in a manner not originally described that, in particular when changing lots, the fleece funnel 1 does not have to be changed as is usual, but only the insert 11 has to be replaced. For the In the event of a batch change, the insert 11 would have a correspondingly changed inside diameter D I.
