Definitions

  • the invention relates to a machine for producing multi-segment filters for the tobacco processing industry.
  • WO 03/024256 A2 a device for assembling groups of filter segments for the production of multi-segment filters of the tobacco processing industry is known, in which the filter segments are assembled and conveyed transversely axially.
  • the assembled groups of filter segments or sub-groups of filter segments are transferred by a transfer device into a longitudinally axially conveyed strand of filter segments, which is then enveloped by a wrapping material so that a corresponding filter strand is formed in a strand process.
  • Corresponding multi-segment filters are then cut to length from the filter rod in order to be processed further accordingly.
  • multi-segment filters are twice the usable length Cut to length to be placed between two tobacco sticks and then cut in the middle to form two filter cigarettes.
  • the use of a plurality of independent functional units that are designed as modules means that there is great variability in the manufacture of multi-segment filters.
  • a corresponding device is also in the EP 1 393 640 B1 disclosed.
  • the assembly during transverse axial conveying of the filter segments and the longitudinal axial conveying during strand production is shown.
  • EP 1 913 824 A1 In order to accelerate the production of multi-segment filters, EP 1 913 824 A1 , EP 1 913 825 A1 and EP 1 767 107 A1 proposed to make the strand formation in two lanes.
  • different concepts are used for the exact positioning of the cut of the strand for the production of the multi-segment filter from a strand of corresponding filter segments.
  • EP 1 913 824 A1 discloses, for example, means for controlling the position of the segment filter groups of the strand relative to the cut of the cutting means.
  • the means here comprise control means with a sensor which is arranged in the vicinity of each continuous filter rod and monitors the passage of at least one filter element in each group. If there are deviations, the speed of a format belt, by means of which the filter rod is conveyed, is adjusted accordingly.
  • EP 1 913 825 A1 goes a different way.
  • the position of the filter segments is varied in the longitudinal axis on the basis of a measurement signal made after the filter strand has been formed.
  • EP 1 767 107 A1 sees a change in the phase of the inlay wheels Depending on the position of the segments in the filter strand.
  • WO2006 / 056271 shows a conveyor drum used in the tobacco processing industry, in which rod-shaped articles are conveyed in longitudinally and axially and then conveyed further transversely. This happens in two lanes.
  • a device for transferring a flow of filter segments or groups of filter segments from the tobacco processing industry that are conveyed transversely axially and are arranged longitudinally axially next to one another when conveying transversely axially, into two longitudinally axially conveyed strands of filter segments or groups of filter segments, an insert member being provided for each strand , which inserts the filter segments or groups of filter segments into the respective strand.
  • Another advantage of the device is that when the filter segments or groups of filter segments are conveyed transversely in the axial direction, before they are transferred into two longitudinally axially conveyed strands, compared to the EP 1 787 534 B1 only half the process speed is necessary.
  • This is due to the fact that preferably two groups of filter segments, of which one group is placed in the first filter strand in the longitudinal axis and the other in the second filter strand in the longitudinal axis, are arranged one behind the other or next to one another in a trough, namely during transverse axial transport .
  • the concept of the arrangement of filter segments or groups of filter segments alongside one another in the longitudinal axis includes, in particular, that these are arranged longitudinally axially one behind the other, in particular in alignment one behind the other.
  • the insert member particularly preferably inserts the filter segments or groups of filter segments directly into a strand. By inserting the filter segments or groups of filter segments, a corresponding strand of filter segments or groups of filter segments is formed. In this case, the insertion takes place longitudinally axially, so that the longitudinal axial conveying direction of the strand or strands results.
  • a single insert member is preferably provided for each strand.
  • the term “insertion” also includes the concept that the filter segments or groups of filter segments can be inserted.
  • the strands formed are preferably moved longitudinally axially with one or more conveying organs that convey the strands longitudinally axially.
  • the insertion members are preferably insertion wheels.
  • the device is particularly preferred when the insert member for one strand can be driven independently of the insert member for the other strand.
  • “Can be driven” is also understood in particular to mean “is or is driven”. In this way, for example, the speed at which the filter segments or groups of filter segments are inserted into the respective strand can be regulated or controlled so that, for example, exactly one cut can be provided at a desired point on the strand for cutting multi-segment filters to length, as was the case in the two on the same day as the present application at the German Patent and Trademark Office by the applicant registered patent applications with the title "Machine for the production and method for producing multi-segment filters of the tobacco processing industry" is described in detail.
  • the insertion members are preferably each rotatable about an axis of rotation.
  • the device is particularly easy to see when the axes of rotation of the insertion members are arranged at an angle of 20 ° to 160 °, in particular 60 ° to 120 °, in particular 80 ° to 100 °, to one another.
