Definitions

  • the invention relates to a sliding drum in the tobacco processing industry.
  • the invention also relates to a machine in the tobacco processing industry, in particular a filter manufacturing machine or filter attachment machine, and a filter rod segment supply device for supplying filter rod segments made from filter rods.
  • conveyor drums are used to transport cigarettes, filter pieces or their components.
  • conveying drums are shifting drums, e.g.
  • filter rods of multiple lengths are removed from a filter rod magazine on a filter feed device having a plurality of transport drums and cut into double-length filter plugs on a cutting drum. After cutting, the filter plugs are staggered on a staggered drum, i.e. each cut filter plug is placed separately in a trough of the staggered drum, offset to the next filter plug.
  • the staggered filter plugs are shifted longitudinally and axially on a sliding drum in the receiving recesses, so that the filter plugs are or are aligned one behind the other in a row in the transverse axial direction, whereby the filter plugs arranged and aligned one behind the other in the row are Sliding drum are transferred to a subsequent conveyor drum.
  • These drums are usually used in the course of the assembly of filter rods and filter cigarettes, with filter rod components of multiple usable lengths being prepared in a so-called transverse process, i.e. transverse to their longitudinal axes, by being subdivided once or several times, staggered and arranged in a row for their subsequent connection with other filter components or smoking article components will.
  • EP 1 013 181 A2 discloses a sliding/cutting drum in which the smoking article components or filter pieces are pneumatically displaced in the receiving recesses against stops by applying suction air to suction bores in the receiving means.
  • m document GB 2 267 021 A describes a filter attachment machine in which filter rods can be removed from two magazines. After a first filter rod has been removed, this filter rod is cut in the middle and pushed apart transversely axially. A second filter rod from the other magazine is then inserted centrally between the sections of the first filter rod. This filter rod assembly is subsequently cut, staggered and pushed onto drums. This process of "cutting, staggering and shifting the filter pieces" is repeated and thus carried out twice in total. The resulting combination filter from the two different filter rods is then transferred to an assembly drum with cigarette rods.
  • DE 10 2013 210 634 A1 discloses a sliding drum for a machine in the tobacco processing industry.
  • One object of the invention is to provide a sliding drum, for example for a filter feed device, in which, among other things, short rod-shaped article segments can be reliably shifted in the longitudinal direction.

  • This provides a full-surface, continuous stop for the rod-shaped articles to be displaced, which reduces or prevents, for example, the loss of filling material in the rod-shaped articles or article segments when the rod-shaped articles are longitudinally axially displaced in the receiving recesses in cooperation with the air flow channel in the area of the stop barrier .
  • the rod-shaped articles or article segments have reconditioned or reconstituted tobacco material as filling material.
