Description
Technical Field
The present invention relates to a conveyor drum for the tobacco processing industry and to a machine, in particular a drum machine, for the tobacco processing industry.
The invention further relates to a method for conveying rod-shaped articles of the tobacco processing industry, in particular filter rods and/or groups of filter segments and/or tobacco rods and/or filter cigarettes, in the transverse axial direction.
Background
In machines of the tobacco processing industry, in particular filter mounting machines or machines for producing alternative smoking products, such as heated non-combustible products or electronic cigarettes, conveyor drums are used for transporting cigarettes, filter components or components thereof.
During the production of cigarettes, filters and filter cigarettes or so-called heated non-combustible products or electronic cigarettes, the transport of the rod-shaped objects described above is generally carried out in modern production machines of the tobacco processing industry by means of transport drums, the sides of which or the drum bodies of which are provided with grooves or receiving channels for receiving the rod-shaped objects for transporting the rod-shaped objects (cigarettes, filter rods or plugs, filter cigarettes) in the transverse axial direction. During transport, 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.
In a filter mounting machine, rod-shaped articles, such as tobacco rods or filter plugs or filter rods, are transported transversely on a transport drum into a receiving slot of the transport drum. The receiving grooves are arranged at a predetermined separation distance on the circumferential surface of the transport cylinder.
The separation distance is understood to be the distance in the transverse direction of the receiving slot. The distance is measured here from the slot center point of a receiving slot to the next slot center point of the adjacent receiving slot of the slot conveyor, which transports the rod-shaped smoking article(s) over the surface, or, in the case of a prismatic receiving slot, from slot bottom to slot bottom. In the case of a roller conveyor (also referred to as a conveyor roller), the separation distance is the length of the (circular) arc or the lateral axial distance between (adjacent) groove center points on a circular line on which the groove center points or groove center point axes of the grooves are arranged.
Furthermore, a conveying drum for conveying rod-shaped articles of the tobacco processing industry is also known from WO 2012/139720A2 and DE 1020019134097 A1.
Disclosure of Invention
The object of the invention is to transport or move rod-shaped articles in a variable manner on transport drums for rod-shaped articles in the tobacco processing industry during the transport of the rod-shaped articles in the transverse axis.
This object is achieved by a conveyor drum of the tobacco processing industry, which has receiving grooves, which are arranged one after the other in the circumferential direction, preferably at regular intervals, for rod-shaped articles of the tobacco processing industry, in particular filter rods and/or groups of filter segments and/or tobacco rods and/or filter cigarettes, wherein the conveyor drum has an axis of rotation and is driven or can be driven in rotation about the axis of rotation, wherein the receiving grooves are each aligned parallel to the axis of rotation, wherein at least one, preferably each, receiving groove has an immovable partial groove surface for a rod-shaped article and a movable partial groove surface for the same rod-shaped article, wherein the immovable partial groove surfaces of the respective receiving grooves extend parallel to the axis of rotation of the conveyor drum, wherein the movable partial groove surfaces of the respective receiving grooves are movable, in particular linearly movable, parallel to the axis of rotation relative to the immovable partial groove surfaces of the respective receiving grooves.
The invention is based on the following idea: for example, in the production of heated non-combustible products in the form of rods or multi-segment filters, individual rod-shaped article segments are repositioned on the conveyor drum during the transverse-axis transport or are aligned on the conveyor drum by or after a longitudinal displacement movement. In this case, the rod-shaped article is moved in the longitudinal direction by the movable partial groove surface of the receiving groove, wherein the rod-shaped article is arranged here on or in the movable partial groove surface. In particular, the rod-shaped article is held in the movable partial channel surface by the negative pressure. By a linear movement of the movable partial trough surface parallel to the axis of rotation of the conveyor drum, the rod-shaped articles are moved in the direction of the longitudinal axis, wherein at the same time the rod-shaped articles are conveyed transversely as a result of the conveyor drum rotating about its axis of rotation. During the transport process of the rod-shaped articles on the transport cylinder, the rod-shaped articles can be transferred or positioned in the receiving trough between the movable partial trough surface and the immovable partial trough surface, respectively.
For example, if during the conveying process rod-shaped articles are to be transferred or moved in the receiving slot in the conveying direction of the longitudinal axis on the conveying cylinder, it is possible (for example by applying a negative pressure in a movable partial slot surface) to transfer the rod-shaped articles from an immovable partial slot surface of the receiving slot into a movable partial slot surface of the receiving slot and then to move or displace the movable partial slot surface together with the rod-shaped articles arranged therein or thereat in the direction of the longitudinal axis (i.e. parallel to the axis of rotation of the conveying cylinder) by means of the movable partial slot surface. After reaching the respective position or being positioned, the longitudinally axially moving rod-shaped article can then be (back) transferred to the immovable part of the groove surface of the receiving groove. Thereby, a repositioning of the rod-shaped article in the receiving slot (Umpostionierung) is achieved during the transverse axial transport of the rod-shaped article on the transport cylinder.
According to the invention, the receiving groove of the transport cylinder is formed by an immovable partial groove surface and a movable partial groove surface. In particular, the immovable partial groove surfaces are formed at the rigid roller body. The movable partial groove surfaces are formed, for example, on or in axially displaceable slides or displacement bodies of the conveyor roller.
In one embodiment of the conveyor drum, it is provided that the immovable partial groove surfaces and the movable partial groove surfaces of the respective receiving groove are arranged one after the other in the circumferential direction of the conveyor drum, and that the immovable partial groove surfaces and the movable partial groove surfaces of the respective receiving groove each interact with one another in such a way that at least one rod-shaped article is arranged or can be arranged between the movable partial groove surfaces and the immovable partial groove surfaces. Whereby the rod-shaped article can be received in the receiving groove.
A further embodiment of the conveyor roller is characterized in that during the rotational movement of the conveyor roller about the axis of rotation, the movable partial groove surfaces of each receiving groove execute a stroke movement between two stroke switching points.
In a further development of the conveyor drum, it is furthermore preferred that the immovable partial groove surfaces and the movable partial groove surfaces of the respective receiving groove have at least one or more suction openings, wherein in particular the suction openings of the immovable partial groove surfaces of the respective receiving groove are arranged at a preferably regular distance from each other in the longitudinal extension of the immovable partial groove surfaces and/or the suction openings of the movable partial groove surfaces of the respective receiving groove are arranged at a preferably regular distance from each other in the longitudinal extension of the movable partial groove surfaces.
Negative pressure is applied to the suction openings (particularly suction openings) of the movable partial trough surface or the immovable partial trough surface, respectively, to hold the rod-shaped articles in the partial trough surface, thereby fixing the rod-shaped articles in the partial trough surface during the conveyance in the transverse axial direction on the conveying rollers. In order to switch the negative pressure at the suction opening of a part of the trough surface, a corresponding control body is arranged in the interior of the conveying cylinder.
According to a further aspect, it is advantageous in the conveyor roller if the movable partial groove surface of the receiving groove is formed on a slide, wherein the slide is linearly movable parallel to the axis of rotation of the conveyor roller.
Furthermore, in one embodiment, the conveyor roller is characterized in that the two immovable partial groove surfaces of the respective two receiving grooves are formed in succession and mirror-symmetrically in the circumferential direction of the conveyor roller. For example, the immovable partial groove surfaces are correspondingly formed on the outer side of the rigid roller body.
In a preferred embodiment, it is provided in the conveyor drum that the two movable partial groove surfaces of the respective two receiving grooves are formed in succession and mirror-symmetrically on a slide in the circumferential direction of the conveyor drum, wherein the slide is linearly movable parallel to the rotational axis of the conveyor drum.
In addition, it is preferable for at least one, in particular motor-type drive, which is provided in particular for one or all of the slides, to be provided in the transport cylinder for displacing one or more, in particular all, of the movable partial groove surfaces of the receiving grooves.
The movable partial channel surface of the receiving channel preferably has a curved, in particular partially cylindrical curved or rounded or flat support surface for the rod-shaped article.
Furthermore, in the case of conveying rollers, it is preferable if the immovable partial groove surface of the receiving groove has a curved, in particular partially cylindrically curved or rounded or flat support surface for the rod-shaped articles.
In order to cut rod-shaped articles on the conveying roller during the transverse-axial conveying, it is provided according to a preferred embodiment that the conveying roller has circumferential grooves for inserting the cutting blades in the circumferential direction and/or that the receiving groove with a corresponding movable partial groove surface and a corresponding immovable partial groove surface has grooves for inserting the cutting blades.
A further embodiment of the conveyor roller is characterized in that a cutting blade is arranged at the conveyor roller. In particular, the cutting blade is inserted into a recess of a movable and immovable partial groove face of the receiving groove in order to cut a rod-shaped article arranged in the receiving groove.
The object is also achieved by a machine of the tobacco processing industry, in particular a roller machine, having at least one conveyor roller as described above. To avoid repetition, reference should be made explicitly to the description above, which applies in a corresponding manner to the machine.
The object is also achieved by a method for conveying rod-shaped articles of the tobacco processing industry, in particular filter rods and/or groups of filter segments and/or tobacco rods and/or filter cigarettes, transversely on a conveying drum as described above. For this purpose, please refer explicitly to the above description. In the case of the use of the conveyor rollers according to the invention, a method for conveying rod-shaped articles in the transverse axis direction is carried out here.
According to a preferred embodiment of the method, it is provided here that the articles move from the immovable partial trough surface of the receiving trough to the movable partial trough surface of the same receiving trough when the articles are conveyed by the conveying rollers and/or from the movable partial trough surface of the receiving trough to the immovable partial trough surface of the same receiving trough when the articles are conveyed by the conveying rollers. In this case, a change in the position of the rod-shaped article in the receiving slot can be achieved during the execution of the method and during the transport of the rod-shaped article arranged in the receiving slot in the transverse axial direction. The rod-shaped article, which is arranged in a stationary manner, for example, in the non-movable partial trough surface, can thus be displaced in its longitudinal extension in the receiving trough by means of the linear displacement of the movable partial trough surface after the transfer to the movable partial trough surface, wherein subsequently in a further embodiment, after the displacement of the rod-shaped article in the longitudinal direction, it can be transferred from the movable partial trough surface of the receiving trough into the non-movable partial trough surface. Whereby the position of the rod-shaped article in the receiving slot can be changed during the transport of the rod-shaped article in the receiving slot in the transverse axial direction. This change in position can also be carried out several times during the transport in the transverse axis direction on the transport cylinder.
For this purpose, in one embodiment of the method, it is furthermore provided that, in particular during rotation of the conveyor drum, the article rod is transported in the receiving slot, by means of a linear displacement of the movable partial slot surface of the receiving slot together with the article rod parallel to the axis of rotation of the conveyor drum by means of the movable partial slot surface, is moved into a cutting position on the conveyor drum, and is then cut into two article sections by means of a cutting blade inserted into a circumferentially encircling recess of the conveyor drum.
By means of the conveyor roller according to the invention, the article bars can be aligned relative to the cutting plane of the cutting blade by a corresponding longitudinal axial displacement of the article bars in the receiving slot.
In one embodiment of the method, it is furthermore advantageous if, in particular during rotation of the conveyor drum, during the conveyance of a plurality of article sections of the group of article sections in the receiving slot, at least one article section is moved into the discharge position on the conveyor drum by means of the movable partial slot surface of the receiving slot by a linear movement of the movable partial slot surface together with the article section or the article sections parallel to the axis of rotation of the conveyor drum.
According to a preferred embodiment, it is furthermore provided in the method that, in particular during rotation of the conveyor drum, during the conveyance of a plurality of article sections of the article section group in the receiving slot, the at least one article section of the article section group is spaced apart in the longitudinal direction relative to the at least one article section of the article section group arranged in the non-movable partial slot surface of the receiving slot by moving the movable partial slot surface relative to one another parallel to the axis of rotation of the conveyor drum, using a movable partial slot surface of the receiving slot, which has at least one article section of the article section group arranged therein, and using a non-movable partial slot surface of the receiving slot, which has at least one further article section of the article section group arranged therein. During the rotation of the conveyor drum, the article sections of the group of article sections in the receiving slot that are not (initially) spaced apart on the conveyor drum can thereby be spaced apart from one another in the longitudinal direction by: at least one article section is arranged in the immovable partial slot face of the receiving slot, and at least one other article section of the group of article sections is arranged in the movable partial slot face of the receiving slot and is spaced apart from the rod-shaped articles arranged at the immovable partial slot face by a linear movement of the movable partial slot face parallel to the axis of rotation of the conveying drum.
In one embodiment of the method, it is furthermore preferred that the article rod in the receiving slot is cut into two article sections by means of a cutting blade inserted into a circumferentially encircling recess of the conveyor drum, and the two article sections are then spaced apart from one another longitudinally on the conveyor drum.

Detailed Description
Within the scope of the invention, features labeled "particularly" or "preferably" are to be understood as optional features.
In the drawings, the same or similar elements and/or components are respectively denoted by the same reference numerals so as to omit re-introduction respectively.
Fig. 1 schematically shows a conveyor drum 10 for conveying rod-shaped articles 21, 22, 23 in the transverse axis direction, which are conveyed into a receiving trough 12 of the conveyor drum 10. The receiving grooves 12 are formed or arranged at regular intervals on the outside of the transport cylinder 10 in the circumferential direction of the transport cylinder.
When transporting the rod-shaped articles 21, 22, 23 on the transport drum 10 having the rotation axis R, the transport drum 10 is driven by a drive and rotates about the rotation axis R for transporting the rod-shaped articles 21, 22, 23 in the transverse axis.
The transport cylinder 10 has a cylinder body 14 with a recess 18 in which a slide body 30 is arranged in a movable manner. During rotation of the conveyor roller 10 about the rotation axis R, the rod-shaped articles 21, 22, 23 arranged in the receiving slot 12 are moved in the longitudinal axial direction by means of the slider body 30. The rod-shaped articles 21, 22, 23 are arranged in the receiving trough 12 of the conveyor drum 10 individually or in pairs or as groups of sections with more than two rod-shaped articles.
In fig. 2, a view of the transport cylinder 10 is schematically shown in an enlarged view. The receiving groove 12 of the transport cylinder 10 is formed here by a non-movable partial groove surface 16 formed on the rigid cylinder body 14 and a partial groove surface 36 of the slide body 30. The partial groove surface 16 of the roller body 14 is designed here as an immovable partial groove surface for the rod-shaped articles 21, 22, while the partial groove surface 36 is designed as a movable partial groove surface for the rod-shaped articles 21, 22.
The slide body 30 can be displaced with its partial groove surface 36 parallel to the axis of rotation R of the transport cylinder. For moving the slider body 30, a corresponding drive (not shown here) for the slider body 30 is provided.
To receive the slider body 30 at or within the roller body 14, the roller body 14 has a corresponding recess 18 in which the slider body 30 is displaceable or displaceable parallel to the axis of rotation R.
As can be seen from fig. 2, the partial groove surface 16 of the roller body 14 and the partial groove surface 36 of the slider body 30 each form a corresponding receiving groove for the rod-shaped article 21 or 22.
Fig. 3 schematically shows a cross section of the receiving slot 12 in a not-to-correct scale or distorted illustration. The receiving groove 12 is formed here by a partial groove surface 16 of the roller body 14 and a partial groove surface 36 of the slider body 30. Radial suction openings 17 and 37, to which a negative pressure can be applied from a negative pressure source, are provided in each of the partial groove surfaces 16 and 36.
In the left-hand sub-figure of fig. 3, there is no negative pressure at the suction holes 17 of the roller body 14 and no negative pressure at the suction holes 37 of the slider body 30. In the middle illustration in fig. 3, there is a negative pressure at the suction opening 37 in order to arrange the rod-shaped article 21 at the (movable) partial slot surface 36 of the displaceable or movable slide body 30, whereas there is no negative pressure at the suction opening 17 of the roller body 14. In this case, the rod-shaped article 21, which is abutted or sucked at the partial groove surface 36, can be held and moved in the longitudinal axial direction together with the slider body 30 by the linear movement of the slider body 30 perpendicular to the drawing plane.
After the rod-shaped article 21 moves longitudinally along with the slider body 30, the negative pressure at the suction hole 37 of the slider body 30 is cut off and simultaneously a negative pressure is applied at the suction hole 17 of the roller body 14, so that the rod-shaped article 21 moves from the partial groove surface 36 of the slider body 30 in the direction of the partial groove surface 16 of the roller body 14 and is held at the (immovable) partial groove surface 16 by applying a negative pressure at the suction hole 17.
If a plurality of rod-shaped articles 21 to 23 are arranged in the receiving slot 12, it is within the scope of the invention that a part of the rod-shaped articles can be held by applying a negative pressure at the suction opening 17 of the roller body 14, while another rod-shaped article of the group of articles is held by applying a negative pressure at the (movable) partial slot surface 36 of the same receiving slot 12 and is moved longitudinally by a linear movement of the slider body 30 while the other rod-shaped articles lying against the partial slot surface 16 of the roller body 14 are not moved.
During the rotation of the conveyor roller 10, the slide body 30 moves in particular linearly between the two stroke switching points and parallel to the rotation axis R of the conveyor roller. By repeating the transfer process between the partial trough surfaces 16 and 36 a plurality of times and the movement of the slide body 30 parallel to the axis of rotation R of the conveyor roller 10, it is possible to convey the rod-shaped articles 21, 22, 23 in the receiving trough 12 in the longitudinal axial direction on the conveyor roller 10 conveyed transversely to the axis and to move the rod-shaped articles 21, 22, 23 in the longitudinal axial direction into a predetermined position (in particular, a discharge position) at the subsequent conveyor roller. In particular, in order to move the rod-shaped articles in the receiving trough 12, a stepwise and possibly multiple longitudinal displacement process is carried out, whereby the rod-shaped articles 21, 22 on the conveyor drum are repositioned in the receiving trough 12.
In the case of the use of a conveyor drum 10 according to the invention, which is part of a drum machine of the tobacco processing industry (not shown here), rod-shaped articles 21, 22, 23 of the group of article sections, which are arranged next to one another in the longitudinal direction in the individual receiving slot 12, can be separated individually at a predetermined discharge region to a subsequent conveyor drum, wherein it is provided within the scope of the invention that the rod-shaped articles are conveyed more than 360 ° in sections (as a process angle) around the rotation axis R of the conveyor drum. In this case, the rod-shaped articles 21, 22, 23 are continuously separated by using the slider body 30 and a plurality of transfers of the rod-shaped articles 21, 22, 23 between the partial trough surface 16 of the roller body 14 and the partial trough surface 36 of the transport slider 30, and are accordingly displaced to the discharge position. For example, in the case of a three-section group of articles, in a first step, the separated sections after the first revolution are dispensed into a discharge position. The second product segment of the segment group is dispensed after the second revolution, wherein the second segment is transferred into the discharge position by a displacement in the longitudinal direction within the receiving slot 12. In a further progressive displacement process, a third article section is dispensed to a subsequent transport drum in the discharge position after a third revolution of the drum.
Another embodiment of a conveyor roller 10 according to the invention is schematically shown in perspective view in fig. 4. A cutting blade 20 is arranged at the conveyor drum 10 in order to cut rod-shaped articles 21, 22, 23 by the cutting blade 20.
For cutting the rod-shaped articles 21, 22, 23, the drum body 14 has, in the circumferential direction, in the region of the cutting blade 20, a circumferential groove 19, which is interrupted by the recess 18. Furthermore, the slide body 30 has a recess 39 in the circumferential direction, into which recess a cutting blade is inserted in the case of positioning of the slide body 30, so that the positioned and aligned rod-shaped articles 21, 22, 23 are aligned before cutting. During cutting, the grooves 19, 39 are aligned flush with one another in the circumferential direction of the conveyor cylinder 10. In fig. 5 a view of the transport cylinder 10 in fig. 4 is schematically shown.
After the cutting process has been carried out on the conveyor roller 10, the article sections formed by the rod-shaped articles 21, 22, 23, respectively, are separated from one another by the return slide 30, wherein one article section remains on the immovable partial slot surface 16 and the other article section rests on the movable slide 30 at the partial slot surface 36 and is separated from the other (immovable) section at the partial slot surface 16 by the return slide 30.
In fig. 6, a method flow for positioning rod-shaped articles 21, 22, 23 by means of the conveyor roller 10 according to the embodiment in fig. 1 is schematically shown in section.
In method step a), the rod-shaped articles 21, 22, 23 are arranged against the suction openings 17 in the partial groove surface 16 of the drum body 14 by applying a vacuum. In order to move the rod-shaped articles 21, 22, 23 toward the partial groove surface 36 of the slider body 30, a negative pressure is applied at the suction hole 37 of the slider body 30, and the negative pressure is cut off at the suction hole 17 of the roller body 14, so that the rod-shaped articles 21, 22, 23 are abutted against the partial groove surface 36 of the slider body 30. This is shown in method step b).
Then, in method step c), the slide body 30 is moved parallel to the axis of rotation R of the conveyor drum 10, so that the rod-shaped articles 21, 22 are moved longitudinally axially together with the slide body 30 in the receiving slot 12. Accordingly, the rod-like articles 21, 22, 23 are moved in the longitudinal direction with respect to the roller body 14 whose relative positions are fixed. Subsequently, in method step d), the rod-shaped articles 21, 22, 23 moving longitudinally are brought into contact with the partial channel surface 16 by applying a negative pressure at the suction openings 17 of the partial channel surface. Here, the article sections 23 are arranged in a discharge position on the conveyor drum 10 and are submitted to the following conveyor drum. This is indicated in method step e) by the dashed line.
At the same time or thereafter, the slide 30 is brought into its starting position as in method step a), wherein subsequently in method steps f), g), h) the slide 30 is moved in a similar manner as in method steps b), c) and d), so that in a further step the rod-shaped article 22 is brought into the discharge position on the conveyor drum 10. The above-described method steps are then repeated again in order to bring the remaining rod-shaped articles 21 into the discharge position.
All of the features mentioned, as well as those available solely from the drawings and also the individual features disclosed in connection with other features, both alone and in combination, are considered essential for the invention. An embodiment according to the invention may be implemented by means of a single feature or a combination of features.
