Description

Roller device for conveying rod-shaped articles of the tobacco processing industry in transverse axial direction Technical Field The invention relates to a roller device for conveying rod-shaped articles of the tobacco processing industry, in particular filter rod segments or groups of filter rod segments, in the transverse axial direction. The invention further relates to a machine for the tobacco processing industry, in particular a multi-segment filter making machine or filter mounting machine (Filteransetzmaschine), and to the use of a roller device. Background Conveyor drums are used in machines of the tobacco processing industry, in particular in filter mounting machines or machines for producing alternative smoking products, like for example heated non-combustible products or electronic cigarettes, for transporting cigarettes, filter segments (Filterst ucket) or components thereof. In the production of cigarettes, filters and filter cigarettes or so-called heated non-combustible products or electronic cigarettes, the above-mentioned transport of rod-shaped objects is usually carried out in modern production machines of the tobacco processing industry by means of transport rollers, the sides of which are #) Or the roller body thereof is provided with a slot or receiving slot for receiving rod-shaped objects (cigarettes, filter rods or plugs, filter cigarettes) for transporting the rod-shaped objects in the transverse axial direction. The receiving groove has a groove bottom. During the transport process, the rod-shaped articles of the tobacco processing industry are usually arranged in rows in succession in the transverse axial direction in the receiving slot. Furthermore, sliding rollers (Schiebetrommeln) are also known as conveyor rollers, for example in filter feed devices at filter mounting machines, on which the filter plugs are moved longitudinally and axially as rod-shaped articles. In this case, at a filter feeder with multiple transport drums, multiple lengths of filter rods are taken from a library of filter rods and cut into double length filter plugs on a cutting drum. After cutting, the filter plugs are staggered on the staggered roller, i.e. each cut filter plug is individually arranged offset relative to the next filter plug in a recess of the staggered roller. The staggered filter plugs are then displaced longitudinally in the receiving groove on the slide roller in a process step such that the filter plugs are subsequently aligned in rows one after the other in the transverse axial direction, whereby the filter plugs arranged one after the other in rows and aligned are submitted from the slide roller to the subsequent conveying roller. These drums are generally used in mass production processes for filter rods and filter rod cigarettes, wherein filter rod elements of multiple use length are prepared in a so-called transverse process, i.e. transversely to their longitudinal axis, by one or more subdivisions, interlacing and subsequent alignment into which they are subsequently connected to other filter elements or smoking article elements (Rauchartikelkomponenten). In EP 1013181A2 a sliding/cutting drum is disclosed in which a smoking article element or filter plug in a receiving slot is pneumatically moved towards a longitudinally movable stop by applying suction air to a suction aperture of the receiving portion. Another conveyor roller configured as a sliding roller is described in EP 3141134 A2. Furthermore, EP 1,700,528 A1 discloses a conveyor drum for the tobacco processing industry, which has a receiving section for rod-shaped articles of the tobacco processing industry and has a mechanically operable and movable slide for longitudinally axially displacing the rod-shaped articles in the receiving section, which conveyor drum is combined with a cutting mechanism arranged at the conveyor drum for cutting the rod-shaped articles. Disclosure of Invention Starting from this prior art, the object of the invention is to improve the process reliability during the transverse-axis conveyance of filter plugs or the like, in particular of different lengths, when rod-shaped articles are conveyed, for example, to a filter feed device, wherein the construction effort should be kept as low as possible. The object is achieved by a drum device for transporting rod-shaped articles of the tobacco processing industry, in particular filter rod segments or groups of filter rod segments, in particular having at least one, in particular first, transport drum, in particular a first transport drum, which has a drum body rotatable about a rotational axis, which drum body has receiving grooves for the rod-shaped articles arranged one after the other in the circumferential direction, a first and a second wobble plate being provided at both end faces of the drum body for each longitudinal axial displacement of the rod-shaped articles in the receiving grooves, wherein the first wobble plate is provided for dis
