Description

The invention relates to a conveyor drum in the tobacco processing industry and a machine in the tobacco processing industry, in particular a drum machine.

In machines of the tobacco processing industry, in particular filter attachment machines or machines for the production of alternative smoke products such as heat-not-burn products or e-cigarettes, conveyor drums are used to transport cigarettes, filter pieces or their components.

The conveying of the aforementioned rod-shaped objects during the production of cigarettes, filters and filter cigarettes or so-called heat-not-burn products or e-cigarettes is generally carried out in modern production machines in the tobacco-processing industry by means of conveying drums, the outer surface of which or the drum body are cross-axial Conveying rod-shaped objects (cigarettes, filter rods or filter plugs, filter cigarettes) is provided with grooves or receiving troughs for receiving the rod-shaped objects. During the conveyance, these rod-shaped articles of the tobacco processing industry are arranged in receiving troughs, generally in rows one behind the other transversely axially.

In filter attachment machines, rod-shaped articles, such as tobacco sticks or filter stoppers or filter rods, are conveyed transversely axially into receiving troughs of the conveyor drum on the conveyor drums. Here, the receiving troughs are arranged at predetermined spacings on the circumferential surface of the conveyor drum.

The division spacing is understood to mean the transverse axial spacing of the receiving troughs. The distance is measured from the trough center of the receiving trough to the subsequent trough center point of the neighboring receiving trough of the trough conveyor transporting the rod-shaped smoking article (groups) on the surface or from trough bottom to trough bottom with e.g. a prism-shaped receiving trough. The pitch of a drum conveyor, also referred to as a conveyor drum, is the transverse axial distance or the length of the (circular) arc between (adjacent) trough centers on the circular line on which the trough centers or trough center axes of the troughs are arranged.

In addition, are out WO 2012/139720 A2 Conveyor drums known in the tobacco processing industry for conveying rod-shaped articles (cf. 3a to 6th ).

One object of the invention is to provide a conveyor drum in the tobacco-processing industry for rod-shaped articles, in which a quick change in diameter format is to be made possible in a simple manner, while the structural complexity is to be kept low.

This object is achieved by a conveyor drum of the tobacco processing industry with in the circumferential direction, preferably at regular intervals, one behind the other arranged receiving troughs for rod-shaped articles of the tobacco processing industry, in particular filter rods and / or filter segment groups and / or tobacco sticks and / or filter cigarettes Has axis of rotation and is driven or drivable to rotate about the axis of rotation, wherein the receiving troughs are each aligned parallel to the axis of rotation, at least one, preferably at least every second, further preferably each, receiving trough each having an immovable support shoulder for a rod-shaped article and a movable support shoulder for the same rod-shaped article, wherein the movable support shoulder of the respective receiving trough is movable relative to the immovable support shoulder of the respective receiving trough, the immovable Auflagesch ulter and the movable support shoulder are arranged one behind the other in the circumferential direction of the conveyor drum and the immovable support shoulder and the movable support shoulder of the receiving troughs each interact with one another in such a way that at least one rod-shaped article is or is arranged between the movable support shoulders and the immovable support shoulders.

The invention is based on the idea that when bar-shaped articles are received in the receiving troughs, the bar-shaped articles each have a linear contact between the bar-shaped article and the immovable, ie rigid, support shoulder of the respective receiving trough and a linear contact between the bar-shaped article and the movable support shoulder the same receiving trough is formed. By changing the relative distance between the movable support shoulder and the immovable, ie rigid, support shoulder of the respective receiving troughs, it is possible to easily carry out a format change on a machine in the tobacco processing industry, since without exchanging conveyor drums and without changing the position of the Conveyor drums on the machine, for example a filter attachment machine, the conveyor drums are set in such a way that the central longitudinal axes of the conveyed rod-shaped articles are always conveyed on the same circular arc as the central longitudinal axes of the articles, regardless of the diameter of the conveyed or to be conveyed rod-shaped articles can. Here, the radius of the circular arc for the central longitudinal axes of the rod-shaped articles on the respective drum is or is kept constant.

The conveyor drum is set up for the transverse axial conveyance of rod-shaped articles, the conveyor drum having a drum body. The drum body is designed with receiving troughs for the rod-shaped articles in the circumferential direction of the drum body.

In the event of a change, in particular in the case of a change in diameter, of the rod-shaped article to be conveyed on the conveyor drum, the relative position of the movable support shoulder and the immovable support shoulder of the receiving troughs is changed and set, which means that the circular arcs of the central longitudinal axes of the rod-shaped articles of a first type and the central longitudinal axes of the rod-shaped articles of a second type can have the same approximately constant radius. When changing the rod-shaped articles to be conveyed on the conveyor drum from rod-shaped articles of a first type with a predetermined diameter to rod-shaped articles of a second type with a predetermined diameter, the diameter of the article of the first type and the diameter of the article of the second type differing from one another differentiate, a quick format change, in particular in diameter, is achieved by means of the conveyor drum according to the invention, the rod-shaped articles being securely arranged in the receiving troughs. Overall, a stepless format diameter change is carried out without exchanging the conveyor drum or other parts on a machine in the tobacco processing industry. Rod-shaped articles of the tobacco-processing industry in the context of the invention are understood to mean rod-shaped objects, such as, for example, cigarettes, filter rods, filter plugs or their (rod-shaped) components.

The term “rod-shaped article of a first type” is understood to mean a certain type of rod-shaped articles to be conveyed in the tobacco processing industry, which have a predetermined diameter and are conveyed transversely axially, for example, on a filter attachment machine using the conveyor drum according to the invention. The term "rod-shaped article of a second type" is understood to mean a certain type of rod-shaped articles to be conveyed in the tobacco processing industry, which have a predetermined diameter and are conveyed, for example, transversely axially on a filter attachment machine and differ in diameter from the rod-shaped articles of the first type distinguish.

In the context of the invention, “rod-shaped articles of the tobacco processing industry” are understood to mean, in addition to filter rods and / or filter segment groups and / or tobacco sticks and / or filter cigarettes, etc., rod-shaped articles of an e-cigarette or rod-shaped components of an e-cigarette. The rod-shaped articles in particular have a length which is greater than their diameter. The rod-shaped articles of the tobacco processing industry can also have a convex shape or a point or the like in one embodiment.

In the case of a production or format change on a machine in the tobacco processing industry, such as a drum machine, there are thus differences in the diameter of the rod-shaped articles to be conveyed.

In addition, an advantage of the conveyor drum according to the invention is that rod-shaped articles of different diameters, for example on a filter attachment machine, can be conveyed alternately without the conveyor drum or drums having to be replaced on this machine. Overall, this reduces the effort for possible reconstruction measures when changing the diameter format when changing from rod-shaped articles of a first type to rod-shaped articles of a second type, since the distance between the immovable, i.e. rigid, support shoulder and the movable support shoulder of the same receiving recess is changed or adapted. Both the rod-shaped articles of the first type and the rod-shaped articles of the second type each have a linear contact with the immovable support shoulder and the movable support shoulder of the same receiving trough on the conveyance of the conveyor drum.

In particular, the conveyor drum is adjustable or the distance between the immovable support shoulder and the movable support shoulder of the same receiving trough that when bar-shaped articles of the first type are received in the receiving troughs of one conveyor drum, the circular arc of the central longitudinal axes of the bar-shaped articles of the first type is the circular arc of the central longitudinal axes of the bar-shaped Article of the second type when rod-shaped articles of the second type are received in the receiving troughs which corresponds or can correspond to at least one conveyor drum.

In addition, it is preferred that the position of the axis of rotation of the conveyor drum on a drum machine, such as a filter attachment machine, remains unchanged when the rod-shaped articles of the first type are conveyed and when the rod-shaped articles of the second type are conveyed.

Furthermore, an embodiment of the conveyor drum is characterized in that the movable support shoulder of each receiving trough in relation to the axis of rotation of the conveyor drum is radially movable and / or movable in the circumferential direction of the conveyor drum. This makes it possible to adapt the distance between the movable support shoulder and the immovable support shoulder in accordance with the diameter of the rod-shaped article to be conveyed. Appropriate guides or scenes are preferably provided for moving the movable support shoulder.

Here, according to a further aspect, it is advantageous that the distance between a reference point of the immovable support shoulder and a reference point of the movable support shoulder can be changed and / or adapted. The reference points of the movable support shoulder and the immovable support shoulder are preferably formed or present in a plane perpendicular to the axis of rotation of the conveyor drum.

In addition, a further development of the conveyor drum is characterized in that the movable support shoulder of a receiving trough can be pivoted about a pivot axis, the pivot axis of the movable support shoulder in particular being aligned parallel to the axis of rotation of the conveyor drum. In addition, the movable and immovable support shoulders are preferably not movable in the axial direction.

In a further development of the conveyor drum, it is advantageously provided that at least one, in particular manually operable or motorized, drive is provided for moving the movable support shoulder of one or more, in particular all, of the receiving troughs. This enables the distance between the movable support shoulder and the immovable support shoulder of the receiving troughs to be set in a simple manner.

Furthermore, a further development of the conveyor drum is characterized in that the movable support shoulder of the receiving troughs is each formed on a movable support body and the support body is attached to the drum body of the conveyor drum by means of a joint, in particular a film hinge. The conveyor drum has a drum body on which the receiving troughs are arranged one behind the other in the circumferential direction, preferably at regular intervals.

For this purpose, it is provided in an advantageous aspect of the conveyor drum that on the side of the support body facing away from the support shoulder, a fluid chamber for the support body which can be or is filled with a fluid is provided, wherein in particular the support body is connected to the fluid chamber and the support body is dependent the amount of fluid / or is moved or is movable as a function of the pressure of the fluid in the fluid chamber.
