Description

Drum arrangement for transversely transporting stick-shaped articles in the tobacco processing industry

The invention relates to a drum arrangement for transporting rod-shaped articles of the tobacco processing industry, in particular filter rod segments or groups of filter rod segments, in the transverse direction.

The invention also relates to the use of machines in the tobacco processing industry, in particular multi-segment filter manufacturing machines or filter attachment machines and drum arrangements.

In machines of the tobacco processing industry, especially machines with filter attachments or machines for the manufacture of alternative smoking products, for example heat-not-burn products or cigarette-type electronic cigarettes, the conveyor drum is used for cigarette-type cigarettes, filter parts. or used to transport their components.

In modern production machines of the tobacco processing industry, during the manufacture of cigarettes, filters and filter cigarettes or heated non-combustible products or cigarette-type electronic cigarettes, the transportation of the above-mentioned rod-shaped objects is usually carried out using a conveyor drum, the outside of which The surface or drum body is provided with grooves or receiving recesses for receiving rod-shaped objects (cigarettes, filter rods or filter plugs, filter cigarettes) for transporting them in the transverse axis. The receiving recess in this case has a recess base.

During transport, these rod-shaped articles of the tobacco processing industry are placed one after another in the transverse direction, generally in a row, in a receiving recess.

Additionally, shifting drums, for example in the filter feeding device of a filter attachment machine, are also known as conveyor drums, in which the filter plugs as rod-shaped articles are displaced in the longitudinal axis direction. In this case, in a filter supply device with multiple transport drums, several lengths of filter rods are withdrawn from a filter rod magazine and cut into twice-length filter plugs in a cutting drum. After cutting, the filter plugs are placed staggered in a stagger drum, i.e. each cut filter plug is placed separately in a recess of the stagger drum with an offset to the next filter plug. The staggered filter plugs are subsequently displaced longitudinally in a receiving recess of the shifting drum in one method step, so that the filter plugs are then aligned transversely in a row, with the result that they are aligned in a row in a row. The filter plugs are transferred from the shifting drum to the subsequent conveyor drum.

Such drums are usually used in the process of mass production of filter rods and filter cigarettes, in which filter rod components of several times the service length are moved in the so-called transverse movement, i.e. transversely to its longitudinal axis, once or several times. By subdividing, staggering and aligning in sequence, it is prepared for subsequent connection with other filter components or smoking article components.

EP 1 013 181 A2 discloses a shifting/cutting drum, in which the smoking article component or filter part within the receiving recess is positioned against a stopper that is longitudinally displaceable by applying suction air to the intake bore of the receiving part. It is displaced pneumatically.

Another conveyor drum designed as a shifting drum is described in EP 3 141 134 A2.

In addition, EP 1 700 528 A1 provides a receiving section for rod-shaped articles in the tobacco processing industry with a cutting device arranged on a conveyor drum for cutting the rod-shaped articles and displacing the rod-shaped articles within the receiving section in the longitudinal axis direction. A conveyor drum for the tobacco processing industry is disclosed having a mechanically operable and movable sifter for the purpose.

On the basis of this prior art, the task of the present invention is to keep the structural complexity as low as possible, for example in the transport of rod-shaped articles in filter feeding devices, especially while transporting filter parts of different lengths, etc. in the transverse axis. This is to increase process safety.

The object comprises at least one, in particular a first, conveyor drum rotatable about an axis of rotation and having at least one drum body with circumferentially arranged receiving recesses for rod-shaped articles in turn, said drum body A first wobble plate and a second wobble plate are provided on both end surfaces, respectively, for displacing the rod-shaped articles in the receiving recess in the longitudinal axial direction, respectively, and the first wobble plate is provided in each receiving recess. It is configured to displace the rod-like article of the first type in the recess along the first displacement direction, preferably only in the direction of the second wobble plate, wherein the second wobble plate comprises a membrane of the second type in the respective receiving recess. and configured to displace the large article along a second displacement direction, preferably only in the direction of the first wobble plate, wherein the first displacement direction of the first type of rod-shaped article is the second displacement direction of the second type of rod-shaped article. Contrary to this, in particular the rod-shaped articles of the first type and the rod-shaped articles of the second type are of different lengths, for transporting rod-shaped articles of the tobacco processing industry, in particular filter rod segments or groups of filter rod segments, in the transverse axis direction. This is solved by the drum arrangement for the problem.

The present invention uses two double-sided wobble plates on the drum body of a conveyor drum to allow rod-shaped articles of the first type and the second type alternately disposed in the receiving recess to move in the receiving recess in opposite directions in the longitudinal axial direction. It is based on ideas that are displaced. Additionally, corresponding respective movement links for the wobble plates are preferably provided for movement of the wobble plates arranged on both sides of the drum body of the first conveyor drum. For example, in this case link guides etc. may be provided for the first wobble plate and the second wobble plate respectively, so that different longitudinal axial displacements of the rod-shaped article can be effected or caused correspondingly.

The length is different from that of stick-shaped items. For the first type of rod-shaped article and the second type of rod-shaped article, the rod-shaped articles of different lengths are aligned, for example centrally, with respect to a stopper fixed, for example, before the cutting process. For this purpose, stopper points for the first type of rod-shaped article and stopper points for the second type of rod-shaped article are respectively fixedly defined.

Within the scope of the invention, the link guide for the first wobble plate for rod-shaped articles of the first type and/or the link guide for the second wobble plate for rod-shaped articles of the second type are adjustable, with the result that the The stroke lengths for the displacement movement by the wobble plate of the rod-shaped article of the first type and of the rod-shaped article of the second type in the respective receiving recesses can in particular be varied independently of each other.

In the scope of the present invention, features characterized as “in particular” or “preferably” should be understood as optional features.

In the drawings, identical or similar elements and/or parts are given the same reference numerals, so repeated descriptions for each case are omitted.

In Figure 1, a part of a drum arrangement (T), which is for example a component of a multi-segment filter manufacturing machine (M), is schematically shown. The drum arrangement (T) has a conveyor drum (10) with respect to the direction of transport of the rod-shaped articles which are transversely conveyed by the drum arrangement (T), in which the rod-shaped articles are moved to the conveyor drum (10). are sequentially placed in the receiving recesses and are transported transversely to the conveyor drum 20 that follows in the transport direction and are transmitted to the corresponding receiving recesses of the conveyor drum 20.

The rod-shaped article transferred from the first conveyor drum 10 to the conveyor drum 20 is cut in the center by the rotary cutting blade 30 disposed on the conveyor drum 20, and the subsequently cut rod-shaped article is transferred to the conveyor. From drum 20 it is transferred to a subsequent additional conveyor drum (not shown).

Other details about conveyor drum 10 and conveyor drum 20 are shown in some of the schematic diagrams of Figures 2 and 3, respectively.

Figure 2 shows a schematic top view of a part of the conveyor drum 10 of the drum arrangement T of Figure 1.
