Definitions

  • the invention relates to a device for removing and combining a nonwoven fabric emerging from a pair of rollers to form a sliver with at least one endless conveyor belt, which is guided by means of a first and second deflecting roller and affects the pair of rollers over its delivery width.
  • the delivery roller pair can also have at least two conveyor belts running in opposite directions, each conveyor belt being able to be guided via a third deflecting roller in such a way that the two conveyor belts run essentially parallel in the direction of transport of the sliver and the sliver is inevitably guided close to one Give the pair of draw rollers.
  • the delivery roller pair is often a pair of squeeze rollers consisting of cylindrical rollers, which crushes the sheet and shell parts still contained in the nonwoven fabric.
  • the rollers are axially interlocked, the extent of which depends on the fiber material being processed and the desired amount of contact pressure depends (DE-PS 1.510.215). Removing the rollers from their axially parallel position, however, has the consequence in the known device that the conveyor belt loses its tangential contact with the rollers over their delivery width. This leads to disturbances when removing and combining the fiber fleece emerging from the pair of rollers.
  • the object of the present invention is to avoid this disadvantage and to ensure proper removal and assembly of the nonwoven fabric even when the position of the rollers relative to one another changes.
  • the object is achieved according to the invention in a device according to the preamble of claim 1 in that the axis of the deflecting rollers of a changed axial position of the rollers is mounted such that they can be tracked relative to one another, and that the conveyor belt is guided over a drive roller arranged at a distance from the axis connecting plane of the deflecting rollers.
  • the run of the fiber sliver running against the rollers can be brought into a position by means of the deflecting rollers in which it no longer lies in one plane, but is so entangled that it tangentially touches the two rollers after the axis has been locked over the delivery width.
  • the deflection rollers are mounted on a wobble pin. It is provided that the pivot point of the wobble bolt is at the height of the central axis of one of the two rollers of the pair of rollers, so that the axial position of one of the rollers can be changed and the position of the conveyor belt can be adapted to it.
  • the wobble pin is rotatably arranged in a bearing plate which can be pivoted about an axis arranged perpendicular to the longitudinal axis of the rollers.
  • the tensioning of the conveyor belt is made possible that the axis is arranged in a bearing plate displaceable in the direction of the longitudinal axis of the rollers.
  • the arrangement of the drive rollers directly next to one another ensures that the conveyor belts, which are parallel to one another in the transport direction of the sliver, give the sliver an inevitable guidance.
  • Access to the sliver outlet between the conveyor belts is facilitated in that the drive roller of each conveyor belt is arranged away from the path of movement of the sliver.
  • the pair of rollers is freely accessible in that the conveyor belts, including their deflection and drive rollers, can be moved away from the pair of rollers.
  • FIGS. 1 and 4 show a pair of nip rollers 1 with an upper roller 10 and a lower roller 11, on the delivery side thereof an endless conveyor belt 2 is arranged.
  • the conveyor belt 2 is guided over a first deflection roller 3 and a second deflection roller 4 in such a way that it tangentially contacts the top roller 10 and the bottom roller 11 of the pair of squeeze rollers 1.
  • the deflection rollers 3 and 4 are adjustably mounted such that their axes can be adjusted to one another to change the axial position of the rollers 10 and 11.
  • the adjustment is preferably carried out by means of a wobble pin 6 on which the deflection roller 3 and, analogously, the deflection roller 4 are mounted (FIG. 4).
  • the wobble pin 6 is rotatably arranged on a machine part 60 in a bearing plate 61 and extends into a bore 30 of the deflection roller 3, in which it is mounted by means of a roller bearing 62.
  • the axial position of the deflection rollers 3 and 4 and thus the position of the conveyor belt 2 can be adapted to the axial position of the two rollers 10 and 11.
  • the axis of only one roller is shifted.
  • the pivot point of the wobble pin 6 is therefore arranged at the level of the central axis of one of the two rollers 10 or 11.
  • the pivot point S of the wobble pin 6 is at the height of the central axis M of the top roller 10, so that with appropriate adjustment of the deflection rollers 3 and 4 by means of the wobble pin 6, the conveyor belt 2 follow an axial displacement of the bottom roller 11 and, for example, brought into the inclined position shown can be in which it touches both rollers of the pair of squeeze rollers 1 tangentially.
  • the pivot point of the wobble pin 6 will be at a height in the first case the central axis of the lower roller 11 and in the second case at the level of the nip line between the rollers 10 and 11.
  • the bearing plate 61 in which the wobble pin 6 is arranged, can be pivoted about an axis 64 running perpendicular to the longitudinal axis of the rollers 10, 11 ( Figure 5).
  • an adjusting screw 65 screwed into the bearing plate 61, which is supported on the machine part 60 the wobble pin 6 with the deflection roller can be pivoted in the alignment of the rollers 10, 11 and the course of the conveyor belt 2 can thereby be corrected.
  • the axis 64 is arranged in a bearing plate 66 which is fastened to the machine part 60 by means of a screw 67. After loosening this screw 67, the bearing plate 66 can be moved by an adjusting screw 68 in the direction of the longitudinal axis of the rollers 10, 11, whereby the conveyor belt 2 is tensioned by the deflecting roller 3.
  • the pair of squeeze rollers 1 are assigned two conveyor belts 21, each of which is guided over the first deflection roller 3 and the second deflection roller 4 and are driven by the drive roller 5.
  • the drive of the two conveyor belts 21 is in opposite directions.
  • the drive rollers 5 are removed from the axis connection plane A of the deflection rollers 3 and 4 and arranged directly next to one another, so that the sliver in the transport direction P 1 receives an inevitable guidance through the parallel parallel conveyor belts.
  • the drive rollers 5 are also in the same drive plane and are driven together via the drive shaft 50.
  • the embodiment of Figure 3 differs from that shown in Figure 2 in that the drive rollers 5 are arranged away from the path of movement of the sliver indicated by the arrow P1, so that access to the sliver run is present.
  • the sliver emerging between the deflection rollers 4 is sucked into a belt funnel 7 designed as an injector and drawn off by a pair of take-off rolls 8.
  • the drive rollers 5 are also in the same drive plane and are driven together via the drive shaft 50.
  • the drive for the puller roller pair 8 is also derived from the drive shaft 50.
  • the conveyor belt 2 or the conveyor belts 21 together with the deflecting rollers 3 and 4 and the drive roller 5 can be pivoted away from the pair of nip rollers 1 to the front.
  • the pivoting movement takes place about the drive axis 50 of the drive roller or drive rollers 5 and is limited by stops 52.
  • the device can also be arranged displaceably in order to allow access to the pair of nip rollers 1.
