  • a spreading device for two or more Hüllmaterialbahnen for producing at least two parallel strands of products of the tobacco processing industry with the features of the preamble of claim 1 and a system with a spreading device with the features of the preamble of claim 17.
  • both the strand-shaped filter material and the strand loose tobacco fibers is fixed by means of a Hüllmaterialbahn.
  • a Hüllmaterialbahn In order to increase the production speed, it has been proven to produce the products in at least the strand forming unit in two or more parallel strands, if no expensive, precut wrapping material is to be used.
  • a Hüllmaterialbahn multiple, especially double, width is first unwound from a reel and cut by means of a cutting device in a continuous cutting process in two or more mutually parallel Hüllmaterialbahnen.
  • the cutting device is formed by a pull-cutting roller assembly in which the multi-width wrapping material web is cut in two or more wrapping material webs of identical width.
  • the parallel Hüllmaterialbahnen be parallel by means of a spreading device offset from each other so that they then parallel and at a distance from each other. This is particularly necessary because the strands are then also in the strand forming unit at a distance and parallel to each other.
  • Such a spreading device comprises a number of Umlenkrollengrupp réelleen corresponding to the number of Hüllmaterialbahnen which are each traversed by a Hüllmaterialbahn such that the Hüllmaterialbahn is deflected at the inlet to the underside of the first guide roller and then at the top of the second guide roller.
  • the pulleys are inclined relative to the deflected Hüllmaterialbahnen, so that the Hüllmaterialbahnen be offset parallel laterally during the deflection.
  • the Spreizabstand the Hüllmaterialbahnen after the passage can be changed by the second pulleys are adjusted in height.
  • the deflection rollers are free-floating mounted on one side, so that the Hüllmaterialbahnen can be threaded from the side of the free ends of the pulleys in the Umlenkrollengrupp réelleen.
  • the pulleys of Umlenkrollengrupp réelleen which pass through the Hüllmaterialbahnen are, are arranged to each other so that the free ends of the pulleys facing each other and have a distance from each other.
  • both Hüllmaterialbahnen be threaded between the pulleys in the Umlenkrollengrupp réelleen.
  • a disadvantage of these solutions is the fact that the threading process of the wrapping material requires a special skill of the person handling and is time-consuming.
  • the invention has for its object to provide a spreading device or a system with a spreading device, in which the threading of the Hüllmaterialbahnen is easier to handle.
  • the lateral parallel offset of the Hüllmaterialbahnen can be designed much more individual than was possible in a conventional spreading with oppositely arranged Umlenkrollengrupptechniken. In extreme cases, it would even be conceivable to offset the wrapping material webs so that they subsequently overlap at least partially in an edge section.
  • the Umlenkrollengrupp réelleen are arranged one above the other like a terrace.
  • the proposed arrangement the Umlenkrollengrupp réelleen are particularly simple and easy to handle for threading the wrapper strip accessible from the side.
  • the threading is particularly simple when the pulleys are mounted on one side free-floating, so that the guideway for the wrapping strip is open at the side.
  • the deflection rollers each have a Umlenkrollengrupp réelle an identical diameter and an identical relative angle to each other.
  • the first and second pulleys of a Umlenkrollengrupp réelle therefore have an identical diameter and are each aligned with the incoming Hüllmaterialbahn that the pulleys of the individual Umlenkrollengrupp réelleen have an identical relative angle to each other, i. the relative angle between the respective first deflection roller and the respective second deflection roller of the different Umlenkrollengrupp réelleen is identical.
  • the relative angle is the angular difference between the longitudinal axes or axes of rotation of the deflection rollers of a Umlenkrollengrupp réelle in the projection in the transport direction, which is the cause of the lateral offset of the Hüllmaterialbahnen, so that this is also identical in result at the individual Umlenkrollengrupp réelleen.
  • the advantage of the proposed solution is the fact that the deflection and thereby caused due to the relative angle angle change of Hüllmaterialbahn between the inlet section and the drain section on the pulleys of different Umlenkrollengrupp réelleen is identical.
  • the deflection is also dependent on the diameter of the pulleys, which is also identical due to the identical diameter.
  • the Umlenkrollengrupp isten are identical and mirror-symmetrical design or aligned, so that the Hüllmaterialbahnen be offset laterally by an identical path.
  • the feeding and discharging directions of the wrapping material webs be aligned parallel to each other towards and away from the Umlenkrollengruppleiteren. Due to the parallel orientation of the Hüllmaterialbahnen in the feed and discharge, the Hüllmaterialbahnlauf can be further uniformed by the likelihood of the occurrence of stresses in the Hüllmaterialbahnen is further reduced by the parallel course of the Hüllmaterialbahnen. As a result, the course of the wrapping material webs can be controlled particularly accurately, which is particularly advantageous for controlling the edge position of the wrapping material webs.
  • the pivot axis lies exactly in the longitudinal center line of the Hüllmaterialbahn, so that the Hüllmaterialbahn the side of the center line in each case by the same angle and in the same Width is pivoted during the adjustment of Umlenkrollengrupp réelle.
  • the Umlenkrollengrupp réelleen are each adjustable by means of an adjusting device formed by a multi-joint mechanism. Due to the multi-joint mechanism, the entire Umlenkrollengrupp réelle can be particularly easily pivoted about the virtual arranged in the Hüllmaterialbahn pivot axis, thereby also the adjusting movement of a linear drive device can be converted into a pivoting movement particularly easy.
  • This can be realized in a particularly simple manner in that the multi-link mechanism transmitting the adjusting movement has a positive guide defining the pivot axis.
  • the forced operation is formed by various joints, which dictate the movement sequence during the pivoting movement by their distances from each other.
  • the adjusting movement transmitting multi-link mechanism is preferably mounted with two first coupling rods in two stationary pivot bearings, wherein the stationary pivot bearings are preferably arranged such that their pivot axes lie on a straight line which extends through the voltage applied to the first deflection roller Hüllmaterialbahn.
  • first coupling rods are preferably coupled together via at least two second coupling rods, at the ends of a support plate is pivotally mounted in each case a pivot bearing, wherein the deflection rollers are arranged on the support plate.

  • the proposed arrangement of the pivot bearing and the dimensioning of the distances of the pivot bearing pivoting of the Hüllmaterialbahn can be made possible by a running in the Hüllmaterialbahn pivot axis, allowing a very accurate control of the edge position of the Hüllmaterialbahn with very low stresses in the lead and lag of the Hüllmaterialbahn can be.
  • it can be prevented that the Hüllmaterialbahn runs laterally during pivoting so far on the guide roller, that the pivot axis of the Hüllmaterialbahn runs outside the Hüllmaterialbahn.
  • the Umlenkrollengrupp istстоen are adjustable by means of a coupled to the second coupling rods drive means.
  • the proposed solution is advantageous in that the drive means can thereby be arranged and fastened at a distance from the Umlenkrollengrupp réelleen, without that has disadvantages for the Verstellgenautechnik, since the second coupling rods are connected directly to the support plates on which the pulleys are held ,

  • the proposed partition and the arrangement the Umlenkrollengrupp réelleen the operator can be protected, for example, during the threading of Hüllmaterialbahnen before an unwanted engagement in the drive means and the associated transmission mechanism for transmitting the drive movement.
  • the drive means, the gear mechanism and the corresponding part of the multi-link mechanism can be protected from external mechanical influences from the operator side. For the operator are aware only the Umlenkrollengrupp réelleen for threading the Hüllmaterialbahnen accessible.
  • the partition wall has recesses, and the multi-joint mechanism passes through the recesses of the partition with the second coupling rods, and the first coupling rods of the multi-joint mechanism on the drive side and the support plates of the multi-joint mechanism on the operator side of the partition are arranged.
  • a spreading device according to the invention can be seen schematically from the side.
  • the spreading device is a Hüllmaterialbahn 1 multiple, in this case double, supplied width of a reel, not shown, and cut in a train-Schneidwalzengrupp réelle 10 into two parallel Hüllmaterialbahnen 2 and 3 simple width.
  • the wrapping material webs 2 and 3, which adjoin each other immediately after cutting, are then supplied with two deflecting roller groups 4 and 5 arranged offset from one another in the transport direction of the wrapping material webs 2 and 3.

  • the Hüllmaterialbahnen 2 and 3 are deflected twice in the Umlenkrollengrupp réelleen 4 and 5, and thereby pivoted due to the inclinations of the pulleys 6,7,8 and 9 in opposite directions.
  • Hüllmaterialbahnen 2 and 3 By the opposite pivoting of the Hüllmaterialbahnen 2 and 3 about their longitudinal axes they are offset laterally parallel to each other so that they run parallel to each other and after running from the second pulleys 8 and 9 at a distance to each other, so are spread.
  • the angles of the pulleys 6,7,8 and 9 to the Hüllmaterialbahnen are chosen so that the Hüllmaterialbahnen are offset by approximately the same amount to the outside, so that the distance between the Hüllmaterialbahnen 2 and 3 then the sum of the lateral displacement movements, and Ideally, in a symmetrical displacement movement of the double displacement movement of a Hüllmaterialbahn 2 or 3 corresponds.

  • the Umlenkrollengrupp réelleen 4 and 5 are offset relative to each other with respect to the transport direction of the Hüllmaterialbahnen 2 and 3, so that they are arranged in a terraced manner due to the obliquely from bottom to top aligned course of Hüllmaterialbahnen 2 and 3. Since Umlenkrollengrupp réelleen 4 and 5 are arranged offset from one another, the Hüllmaterialbahnen 2 and 3 can be much easier inserted laterally, since the Umlenkrollengrupp réelleen 4 and 5 are now accessible from the side. The improved accessibility is achieved in particular by the terrace-like arrangement of Umlenkrollengrupptechniken 4 and 5, since the Umlenkrollengruppmaschineen 4 and 5 no longer overlap laterally.

Further, the multi-link mechanism with the ends of the coupling rods 14,15 and 29 is mounted in pivot bearings 27 and 28 on a machine-fixed holder 18.
  • the guide rollers 6 and 8 are mounted on one side of a support plate 20 free-floating, which in turn is pivotally supported at the free ends of the coupling rods 16 and 17. Further, a linear drive means 19 is provided, which is connected to the remote from the first guide roller 6 end of the support plate 20.
  • the multi-joint mechanism is designed, and in particular has such a positive guide, that the linear drive movement of the drive means 19 is converted into a pivoting movement of the entire multi-joint mechanism with a pivot axis C tangent to the surface of the first guide roller 6.
