Definitions

  • the present invention relates to a device for compacting and guiding fiber sliver, in particular on a spinning preparation machine with a sliver funnel, take-off rollers arranged downstream of it and guide surfaces encompassing the take-up rollers on both sides.
  • a belt funnel which opens directly before the nip of a pair of rollers.
  • the pair of rollers consists of a disc-shaped roller and a roller provided with a circumferential groove.
  • the thickness of the disk-shaped roller is adapted to the circumferential groove of the other roller, so that a fiber sliver clamped between the two rollers is guided laterally from the cheeks of the circumferential groove.
  • Disadvantages of this embodiment are the relatively high outlay for the production of the roll with the circumferential groove and the large assembly outlay when adjusting the rolls to one another.
  • the object is achieved in that lateral distances between the guide surfaces on the take-off roller or the take-off rollers can be set independently of one another.
  • the pair of take-off rolls is located, for example, in one section.
  • the guide surfaces can be assigned to the belt hopper and the pair of draw-off rollers according to their respective tolerances. This makes it easy to adapt the guide surfaces to the belt hopper and the take-off rollers. Friction of the take-off rollers on the guide surface or the belt funnel is avoided.
  • the distance between the guide surfaces and the pair of draw-off rollers can advantageously be adjusted by means of shims of different thickness and / or number between the guide surfaces. If the guide surfaces are guide plates, the shims are arranged between the guide plates. In the case of annular disks arranged laterally next to the take-off rollers as guide surfaces, the distance can be adjusted by means of adjusting disks which are arranged between the take-off roller and the annular disks.
  • the guide surfaces are guide tabs which are arranged on a carrier of the band funnel.
  • the distance between the guide plates and the take-off rollers can be adjusted by means of shims between the guide plates and the carrier.
  • the guide straps are arranged on the belt funnel with a screw arranged transversely to the running direction of the sliver, simple assembly and adjustment of the guide straps on the belt funnel is ensured.
  • shims are only inserted between the support of the belt funnel and the guide plates and then pressed together using the screw.
  • the arrangement of mutually corresponding edges on the band funnel and on the guide plate ensures that the guide plates are sufficiently secured against rotation.
  • Figure 1 is a belt funnel 1 with guide surfaces arranged thereon shown.
  • the guide surfaces are guide tabs 2 or 2 '.
  • the guide tabs 2, 2 ' are attached to a carrier 4 of the band funnel 1.
  • the attachment is carried out via a screw 5, which presses the guide tabs 2, 2 'transversely to the conveying direction of a sliver 15 on the carrier 4.
  • an edge 6 of the band funnel 1 is assigned to an edge 7 of the guide plates 2, 2'.
  • the screw 5 is arranged in the carrier 4 such that it is at a distance a from the funnel exit of the funnel opening 3 of the band funnel 1 and thus does not touch it. This ensures trouble-free passage of the sliver 15 through the sliver funnel 1 and the funnel opening 3.
  • the guide tabs 2, 2 ' serve to limit the gap S between the take-off rollers 10 and 11 at the side.
  • the guide tabs 2, 2' have the effect that the fiber sliver 15, when it comes between the take-off rollers 10 and 11, does not laterally next to the take-off rollers 10 and 11 can emerge. This is particularly important if the take-off rollers 10 and 11 are used to control the thickness of the sliver (see double arrow) and the take-off rollers 10 and 11 are more or less far apart from one another by changing the cross-section of the sliver 15 (see double arrow).
  • one of the take-off rollers 10 or 11 is deflected and a signal corresponding to the thickness of the fiber sliver 15 is available. It is precisely here that it is necessary to ensure that there is no sliver 15 to the side of the take-off rollers can emerge and thus causes a falsification of the measurement compared to the actual strength of the fiber band 15.
  • Shims 8 and 9 are arranged between guide plates 2, 2 'and carrier 4 of the band funnel 1.
  • the spacing of the guide plates 2, 2 'from the carrier 4 can be adjusted by the shims 8 and 9 in accordance with the thickness of the shims 8 and 9 enclosed.
  • the use of corresponding shims 8 and 9 is, according to the invention, dependent on the distances between the guide plates 2, 2 'from the take-off rollers 10 and 11.
  • the band funnel 1 is shown in a front view.
  • the guide tabs 2 and 2 ' are fastened to the carrier 4 with the screw 5.
  • Shims 8 and 9 are arranged between the guide plates 2 and 2 'and the carrier 4.
  • the spacing c and d of the guide plates 2 and 2 'from the take-off rollers 10 and 11 and a distance b of the guide plates from one another can be adjusted by means of the shims 8 and 9.
  • a value of approximately 1 mm has proven to be an advantageous overall thickness and thus a possibility of varying the distance b between the guide plates 2, 2 '.
  • the device according to the invention advantageously offers the possibility of carrying out the adjustment of the guide tabs 2, 2 ′ in accordance with the material of the fiber sliver 15 that is guided through the sliver funnel 1. It has been found that, in particular in the case of bulky and / or synthetic fiber material, the processing has been significantly improved if the distances c, d of the guide plates 2, 2 'from the take-off rollers 10, 11 have been set greater than in the case of non-bulky fiber material or in the case of natural fibers. In the case of bulky and synthetic material in particular, there was previously a risk that fibers would become jammed between take-off rollers 10, 11 and guide plates 2 and thus lead to processing malfunctions.
  • FIG. 1 A further exemplary embodiment of the invention is shown in FIG.
  • guide surfaces are arranged laterally on the take-off roller 11.
  • the take-off roller 11 and guide disks 20 and 20 ′ arranged thereon are fastened on a shaft 23.
  • Shims 21 and 22 are arranged between the guide disks 20 and 20 'and the take-off roller 11.
  • the lateral guidance of the sliver 15 can also be adjusted via the shims 21 and 22.
  • the guide disks 20 and 20 ' are also adaptable with respect to the take-off roller 10 and the outlet of the funnel opening 3 of the belt funnel 1.
  • the guide disks 20, 20 ′ rotate with the take-off roller 11.
