Description

The invention relates to a device for processing articles of the tobacco processing industry of the type containing at least one body made of magnetic or magnetizable material, with at least one holding device for holding at least one such article, wherein the holding device is designed such that it can be held while the article is being held at least temporarily allows a change in the position of the article, and a magnetization device is provided to bring the article held by the holding device into a defined position.

In articles of the tobacco processing industry, metal bodies, in particular in the form of flat metal bands or strips, which are contained in the base rods, for example in the WO 2017/072149 A1 is described. The articles of the tobacco processing industry are in particular intermediate products for the production of cigarettes or also finished products such as cigarettes, the base rods preferably having smokable material such as tobacco material in which the at least one metal body is incorporated. In particular, the articles of the tobacco processing industry in the present context are so-called "heatnot-burn" articles, in which metal strips are used to enable the generation of the required heat, to support or influence. This can be achieved by means of induction, provided the metal strip has ferromagnetic material. The base rods are cut once or several times in a further process, not least in order to make short rods or stoppers that are generally difficult to handle as late as possible in the process. The base rods arriving for the cutting process assume a random position or location with regard to the orientation of the metal bodies or flat metal strips with respect to the knife. This means that, depending on the orientation of the metal bodies or flat metal strips to the knife, the resistance during cutting is different. This has an impact on the cutting process and in particular on the cutting result and also the wear and tear on the knife. In certain positions of the article or base rods, in which the metal bodies or flat metal strips adopt a corresponding orientation, it can happen that the cutting process can only be carried out with greater difficulty and does not lead to the desired cutting result, especially when the metal bodies or flat metal strips Due to their position, metal strips generate an increased cutting resistance or lead to a particularly strong resilience of the base rods, which likewise prevents effective cutting.

The EP 1 447 016 A1 , which forms the closest prior art on which the present invention is based, discloses a conveyor drum for articles in the tobacco processing industry with at least one magnetic lifting device which is designed to measure the distance between longitudinally axially aligned articles and conveyed in two rows transversely axially to the conveyor drum to zoom in and out again.

From the DE 10 2013 009 676 A1 a conveyor drum of the tobacco processing industry for transporting articles of the tobacco processing industry is known with a drum body on the surface of which a plurality of segments for receiving the articles are arranged. Plain bearing plates are arranged between the inside of the segments and the surface of the drum body to prevent signs of wear on the surface of the drum body and / or on the inside of the segments essentially to be avoided. In a preferred embodiment, the sliding bearing plates are releasably attached to the surface of the drum body with the aid of magnetic forces, for which purpose magnets are provided at predetermined points on the surface of the drum body, with each of which a sliding bearing plate comes into adhesive engagement.

It is an object of the present invention to propose means for a device of the type mentioned at the beginning, whereby the cutting process can be simplified uniformly for each article to be processed and leads to a consistently good cutting result.

This object is achieved with a device for processing articles of the tobacco processing industry of the type containing at least one body made of magnetic or magnetizable material, with at least one holding device for holding at least one such article, wherein the holding device is designed such that it is held during holding of the article at least temporarily allows a change in the position of the article, and a magnetization device is provided to bring the article held by the holder device into a defined position, the holder device being designed such that it at least temporarily changes the position of the article while the article is being held Permits position of the article by rotation about a longitudinal axis of the article in a defined angle of rotation position determined as a defined position.

Accordingly, the invention proposes aligning the articles of the tobacco processing industry of the type containing at least one body made of magnetic or magnetizable material in a defined position, in particular in a defined position which is particularly favorable and therefore advantageous for the subsequent cutting process. For this purpose, the invention makes use of the knowledge that a body made of magnetic or magnetizable material can be influenced in terms of its position by magnetic force. Therefore, the invention teaches the use of a magnetizer that produces a magnetic force generated, which acts on the at least one body made of magnetic or magnetizable material in the article in order to bring the article into the defined position. For this purpose, according to the invention, the holding device is furthermore to be designed in such a way that it allows the position of the article to be changed at least temporarily while the article is being held by either briefly switching off the holding device completely and thus becoming ineffective or reducing the holding force generated by the holding device to such an extent that the article is still held a little by the holding device, but its position can be changed at the same time; Accordingly, according to the invention, the holding device causes the article to be held in a variable position, at least while the article is being brought into the defined position with the aid of the magnetizing device, in such a way that the article does not detach from the holding device.

The holding device is designed in such a way that while the article is being held it at least temporarily allows the position of the article to be changed by rotating it about a longitudinal axis of the article into a defined angle of rotation position determined as a defined position. According to this, the rod-shaped article is not held in a rotationally fixed manner by the holding device, but rather freely rotatable, at least as long as the magnetizing device is effective in order to turn the article into the specific, defined rotational angle position.

This ensures that the alignment of the articles is optimal in the cutting position in the subsequent cutting process. Furthermore, the invention ensures a reproducible alignment of the articles, which is also important for achieving a uniform and constant cutting result. In view of all of this, the invention offers a possibility in a structurally simple and at the same time effective way whereby the cutting process can be simplified in the same way for each article to be processed and leads to a consistently good cutting result.

Preferred embodiments and developments of the invention are given in the dependent claims.

The device according to the invention is preferably used for aligning at least one article of the type containing a magnetic or magnetizable metal strip.

In order to make it easier to move the article held by the holding device into the defined position due to the action of the magnetizing device, the holding force generated by the holding device should expediently either be switched off or at least set or reduced to such a value while the article is being moved into the defined position that allows the position of the item to be changed. In the case of using a suction device to hold the article on the holding device by suction force, while the article is being brought into the defined position with the aid of the magnetization device, it is expedient to either switch off the suction device and thus be ineffective, or to only generate a suction force that causes a change the position of the article.

Another preferred embodiment of the invention is characterized in that the holding device has at least one stationary bearing element and at least one conveying element movably mounted on the stationary bearing element, which is provided for transporting at least one article along a transport path and has at least one receiving section for receiving at least one article, and the magnetization device is designed, at least the article received by the receiving section of the conveying element during the movement of the conveying element to spend along a section of the transport route in the defined position. The advantage of this embodiment is that it combines two functions, namely on the one hand the transport of the articles from a preceding processing station to a subsequent processing station in which the cutting process takes place in particular. The conveying element is preferably provided for transporting at least one article transversely to the longitudinal extension of the article. Furthermore, the receiving section is preferably designed as an outwardly open trough. In particular, the conveyor element is provided as a conveyor belt movably mounted on the bearing element or as a conveyor drum rotatably mounted on the bearing element, which is preferably designed as a troughed drum, wherein the stationary bearing element can preferably have a control flange or be designed as a control flange. It is advantageous to provide not only the magnetization device in the area of the transport path of the conveyor element or adjacent to the conveyor belt or to the circumference of the conveyor drum, but also a further processing station downstream, such as a cutting station in particular, so that the articles held on the conveyor element are not only transported from a preceding processing station to a next processing station and thereby aligned, but are also subjected to further processing in the subsequent processing station during transport by the conveying element.

According to one of the preferred embodiments mentioned above, it is possible to adjust or reduce the holding force in such a way that the articles are still held on the holding device, but their position can be changed at the same time. However, in addition or as an alternative to this, it is preferably proposed that the holding device in the area of the section of the transport path has a cover element, in particular designed in the manner of a hood, which at a distance from the at least one receiving section of the conveyor element during the movement of the conveyor element along the section of the transport path opposite, which corresponds at least to the thickness of the article received in the receiving section, in order to prevent inadvertent detachment of the article from the holding device and thus from the associated receiving section. It should be such a Cover element be arranged so that a clamping engagement with the articles is avoided, but the article, if at all, only loosely touch the inside of such a cover element. Alternatively, it is also conceivable to provide such a cover element on other designs of the holding device which, for example, do not have a conveying element.

At least a part or a section of the magnetization device is preferably arranged on or in the holding device and, if a conveyor element is used, on or in the bearing element and / or on or in the conveyor element and furthermore preferably adjacent to the at least one receiving portion. These designs have the particular advantage of arranging the magnetization device at least partially in a space-saving manner and preferably providing it on components that are already present, such as a control flange, which thus also function as a carrier for the at least one part or section of the magnetization device.

The magnetization device preferably has at least one magnetic or magnetizable body which has a first pole end forming one pole and a second pole end forming the other pole. In a further development of this embodiment, the aforementioned part or section of the magnetization device can be formed by the at least one magnetic or magnetizable body. Furthermore, the first pole end of the magnetic or magnetizable body can be arranged adjacent to a receiving section. Furthermore, it is conceivable to orient the magnetic or magnetizable body with its first pole end either at certain times or permanently in the direction of a receiving section so that the magnetic field lines emerging from the first pole end penetrate the receiving section at least to a greater extent. In an additional development, the magnetization device has a plurality of magnetic or magnetizable bodies, of which one body is assigned to a receiving section. These magnetic or magnetizable bodies can preferably be switched on and off with regard to their effect, which means that the articles can be brought into the defined area Position can be specifically controlled depending on the requirements of the respective operating state and / or the respective transport position, for which purpose the magnetic or magnetizable bodies are preferably designed as electromagnets.

In order to increase the magnetic influence, the magnetization device can preferably have means for bundling the magnetic field lines penetrating the article, which in particular run essentially parallel in the region of the article and occur there in a higher density. This embodiment is furthermore advantageous, even in the case of an asymmetrical arrangement of the magnetic or magnetizable bodies or metal strips in the articles, to ensure the desired alignment effect in an effective manner.

A further development of this embodiment is characterized in that the means for bundling the magnetic field lines have at least one first magnetic or magnetizable body and at least one second magnetic or magnetizable body, the arrangement of the at least one first body and the at least one second body being made in this way that at least while the article is being moved into the defined position with the aid of the magnetization device, a pole end of the first body that forms one pole is opposite a pole end of the second body that forms the other pole at a distance corresponding to at least the thickness of the article, and the holding device is designed in this way is that the at least one article is to be arranged in the space formed between these two pole ends or can be moved through the space formed between these two pole ends.

In a further development, the aforementioned part or section of the magnetization device is formed by the first magnetic or magnetizable body and the at least one second magnetic or magnetizable body is preferably arranged in a spatially fixed manner Bearing element rotatably mounted conveyor drum this second magnetic or magnetizable body is provided on the bearing element, which can be, for example, a control flange.

In a further development, the magnetization device can have a plurality of first magnetic or magnetizable bodies, of which one body is assigned to a receiving section.

In an alternative development, the first magnetic or magnetizable body can form a first end section and the second magnetic or magnetizable body can form a second end section of a magnetic or magnetizable yoke. The magnetic or magnetizable yoke can preferably be arranged in a spatially fixed manner, whereby in the case of using a conveyor drum rotatably mounted on a fixed bearing element for the fixed spatial arrangement of the magnetic or magnetizable yoke, the fixed bearing element is preferably suitable, which can be a control flange, for example .

In order not to adversely affect the effect of the magnetization device, the holding device should preferably be non-magnetic or comprise non-magnetizable material, at least in the effective area of the magnetization device. In the event that the magnetization device has a conveying element, this preferably applies to the conveying element.

Fig. 1 shows a preferred first embodiment of a processing device, which is preferably part of a machine for the production of so-called "heat-not-burn" articles.

The device contains a drum 2, which has a drum body 4 designed in the manner of a sleeve or a hollow cylinder, which is rotatably mounted around a fixed bearing base 6 about an axis of rotation 4a, which is preferably a control flange. The drum body 4 is provided along its circumference with in cross-section approximately semicircular, outwardly open troughs 8, which are aligned parallel to the axis of rotation 4a of the drum body 4 and are arranged side by side over the entire circumference of the drum body 4; therefore the drum 2 in the illustrated embodiment is a trough drum. The drum body 4 is set in rotation in the direction of arrow A by a drive (not shown).

The troughs 8 of the drum body 4 each serve to accommodate a so-called base rod 10. The illustrated base rods 10 each contain a narrow, thin, flat metal strip 10a which extends in their longitudinal direction and is also referred to as a metal strip and which is at least partially and / or partially ferromagnetic Material, preferably iron, and are used to produce "heat-not-burn" articles in which the metal strips 10a are used to generate the required heat by means of induction. In order to hold the base rods 10 in the troughs 8 during the transport through the rotating drum body 4, the base rods 10 there are subjected to a suction or negative pressure. For this purpose, a negative pressure generating device, not shown in the figures, is provided, which is connected to suction or negative pressure zones 12a, 12b formed in the bearing pedestal 6. The negative pressure zones 12a, 12b extend over a certain angular range, as in FIG Fig. 1 is indicated, and communicate via a channel system (not shown) temporarily with those troughs 8 in the drum body 4 that are currently move along the negative pressure zones 12a, 12b and are in their effective range.

In Fig. 1 An inlet area is identified by the reference symbol "14", where the base rods 10 arrive from a preceding processing station (not shown in the figures) and are received one after the other in the troughs 8 during the rotation of the drum body 4. The incoming base rods 10 can be fed in and transferred to the drum body 4 in the region 14, for example with the aid of gravity through a shaft from which in Fig. 1 only a lower guide plate 14a is shown, or with the aid of a further conveyor drum, not shown in the figures, upstream of drum 2. During the continued rotation of the drum body 4, in the illustrated embodiment, the base rods 10 are guided past a cutting station, from which in FIG Fig. 1 a cutting knife 16 designed as a rotating disk is shown schematically in order to cut the base rods 10. Alternatively, it is also conceivable to provide a knife carrier as the rotating disk, on the circumference of which at least one cutting knife is arranged. Depending on the need and application, the base rods 10 can be cut not only once, but also several times, for which purpose several cutting knives are to be arranged next to one another in the direction of the axis of rotation 4a. Accordingly, the in Fig. 1 The drum 2 shown in particular has the task of guiding the base rods 10 along the cutting station with the cutting knife so that they can then be cut there. Downstream of the cutting knife 16, the cut base rods are then released from the troughs 8 of the drum body 4 and thus discharged from the drum 2 in order, for example, to be further processed in a subsequent station not shown in the figures; for this purpose, for example, the transfer to a subsequent trough drum, also not shown in the figures, can take place. For a smooth delivery of the cut base rods, it is necessary to switch off the negative pressure in the troughs 8 when they arrive in the area 18. Therefore the negative pressure zone 12b ends there, like Fig. 1 reveals.

How Fig. 1 Furthermore, as can be seen, the base rods 10 arriving in the area 14 assume a random angular position with regard to the orientation of their metal strip 10a, with the result that the metal strips 10a are oriented differently. This would lead to the fact that, depending on the orientation of the metal strips 10a with respect to the cutting knife 16, the resistance during cutting would be different. This would have at least partially undesirable effects on the cutting process and in particular on the cutting result as well as on the wear and tear of the cutting knife 16. In certain positions of the base rods 10, in which the metal strips 10a assume a corresponding angular position, it could then happen that the cutting process is only under greater difficulties could be achieved and could not lead to the desired cutting result, especially if the metal strips 10a, due to their position, generate increased cutting resistance or lead to a particularly strong resilience of the base rods 10, which would prevent effective cutting with the cutting knife 10.

In order to achieve a consistently good cutting result for each base bar 10 and thereby simplify the cutting process evenly for each base bar 10, the base bars 10 must be brought into the same defined angular position with regard to the orientation of their metal strips 10a before they arrive at the cutting knife 16. For this purpose, a magnetization device 20 is provided in the region of the drum 2, which generates a magnetic force which acts on the metal strips 10a in order to bring the base rods 10 equally into the defined angle of rotation position. This makes use of the fact that the metal strips 10a consist of ferromagnetic material and can therefore be influenced with regard to their rotational position by magnetic force. However, in the effective area of the magnetization device 20, it must be ensured that the base rods 10 can also be rotated for the alignment process in the troughs 8, that is to say can be subjected to a rotary movement about their longitudinal axis. For this purpose, in the illustrated embodiment, it is necessary to briefly switch off the negative pressure in the respective trough 8 when this moves through the effective area of the magnetization device 20 due to the continued rotation of the drum body 4. That is why the Magnetization device 20, a negative pressure zone does not exist or is interrupted, so that in the illustrated embodiment two negative pressure zones 12a, 12b are formed, of which one negative pressure zone 12a is provided upstream in front of magnetization device 20 and the other negative pressure zone 12b downstream behind magnetization device 20, as in FIG Fig. 1 is shown schematically. In contrast to the representation of Fig. 1 Alternatively, however, it is also conceivable to reduce the distance between the two negative pressure zones 12a, 12b in the effective area of the magnetization device 20 to a dimension that is narrower than the effective area of the magnetization device 20 and in particular than the width of the troughs 8 or the base rods 10, so that when entering and exiting the active area of the magnetization device 20 there is initially an overlap area in which both the negative pressure and the magnetic force act simultaneously and thus in combination until the base rod 10 lying in the trough 8 after entering the effective area of the magnetization device 20 is only acted upon by the magnetic force and, after exiting the effective area of the magnetization device 20, again only subjected to negative pressure.

In the in Fig. 1 In the illustrated embodiment, the magnetization device 20 has a first magnet 21 and a second magnet 22. Both magnets 21, 22 are each arranged stationary, ie fixed in space, namely the first magnet 21 within the bearing base 6 and the second magnet 22 at a distance outside the drum body 4. Furthermore, both magnets 21, 22 are arranged at a distance from one another and thus form a gap between them through which the drum body 4 runs. In the embodiment according to Fig. 1 Both magnets 21, 22 are designed as elongated bodies and lie on a common longitudinal axis 24 which is oriented at an angle to the direction of movement of the drum body 4. The poles of the two magnets 21, 22 are aligned with one another in such a way that the magnetic field lines 26 exit one of the two magnets 21, 22 and re-enter the opposite other of the two magnets 21, 22, as Fig. 1 reveals.

In the illustrated embodiment of Fig. 1 the external second magnet 22 is designed as an electromagnet and accordingly has an electrical coil 22b wound around a ferromagnetic core 22a. Due to its property as an electromagnet, the magnetic field is thus actively generated by the second magnet 22, the magnetic field lines 26 being bundled due to the opposing arrangement of the first magnet 21 and still condensing to the metal strip 10a in the base rod 10 located in the effective area of the magnetization device 20, as Fig. 1 can be seen schematically For this purpose, it is sufficient to provide the first magnet 21 with ferromagnetic material. So that the effect of the magnetization device 20 is not negatively influenced, the drum body 4 consists of non-ferromagnetic material. The bearing base 6 should also consist of non-ferromagnetic material, at least in the area of the first magnet 21.

Further leaves Fig. 1 recognize the arrangement of a cover hood 28, which is provided in the area of the vacuum-free zone, i.e. in the area between the two vacuum zones 12a, 12b and is mounted outside the drum body 4 at a distance from the bottom of the troughs 8, which is at least slightly greater than the thickness of the in The base rods 10 received in the troughs 8, so that a clamping engagement with the base rods 10 is avoided, but the base rods 10, if at all, only loosely touch the inside of the cover 28. The covering hood 28 has a correspondingly curved shape and serves to prevent the base rods 10 from accidentally falling out of the troughs 8 in the effective area of the magnetization device 20.

In Fig. 2 are two variants of the magnetization device compared to the in Fig. 1 The embodiment shown is shown, and based on these variants, the alignment principle can also be clearly recognized.

In the Figures 2a to c a variant is shown in which the magnetization device only uses the second magnet 22 of Fig. 1 has, which, however, has a stronger scattering of the magnetic field lines 26 to the outside after their exit from the electromagnet 22 result, such as Fig. 2a can be clearly seen in which the course of the magnetic field lines 26 without being influenced by the metal strip 10a a base rod 10 is shown. Accordingly, the magnetic field lines 26 are not bundled in the area of the base rods 10 passing through. The distribution of the magnetic field lines 26 thus takes place as in the case of a simple open yoke. However, the alignment effect can also be achieved with this variant, namely also in the case of an asymmetrical insertion of the metal strip 10a within the base rod 10, since the metal strip 10a brings about a higher field line density, as a comparison of FIG Figure 2b With Fig. 2a reveals. Even if an asymmetrical inlay of the metal strip 10a within the base rod 10 as an undesirable misalignment is fundamentally not wanted, an alignment in the defined rotational position can nevertheless also be achieved with this variant. Figure 2c shows in this variant the alignment effect with symmetrical and thus optimal insertion of the metal strip 10a in the base rod 10, whereby an even stronger compression of the magnetic field lines 26 is achieved. In Figure 2c Thus, the base rod 10 with its metal strip 10a is shown in the same defined angle of rotation position as in FIG Fig. 1 .

In the Figures 2d to f a further variant of the magnetization device is shown, in which the two magnets 21, 22 of Fig. 1 each form part of a common yoke 30. Thus, in this variant, the magnetic field lines 26 are bundled in the same way as in the case of FIG Fig. 1 shown embodiment, both for the case of an asymmetrical insertion of the metal strip 10a in the base rod 10, such as Fig. 2e can be seen, as well as for the more desired case of a substantially symmetrical insertion of the metal strip 10a in the base rod 10, such as Fig. 2f reveals. As in the example of Fig. 2e As can be seen, in the case of an asymmetrical insertion of the metal strip 10a in the base rods 10, an alignment in the desired defined rotational position can nevertheless be achieved.

After alignment in the defined rotational position by the magnetization device 20 and then leaving the effective area of the magnetization device 20, the base rods 20 remain held in the defined rotational angle position in the depressions 8 due to the then re-established negative pressure in the region of the negative pressure zone 12b, as Fig. 1 can also be seen schematically.

In Fig. 3 a further embodiment of the invention is shown, which differs from the first embodiment according to Fig. 1 differs in particular by a further variant of the magnetization device. The magnetization device according to Fig. 3 has a plurality of magnets 23, the number of which corresponds to the number of troughs 8. The magnets 23 are arranged within the drum body 4, each magnet 23 being assigned to a trough and one of its poles aligned with this so that the magnetic field lines generated by the magnet 23 run through the associated trough 8, creating the desired force of attraction on the metal strips 10a the base rods 10 deposited in the troughs 8 act. It is preferred to hold the base rods 10 in the troughs 8 also in the embodiment according to FIG Fig. 3 Negative pressure as in the execution of Fig. 1 used, so in a similar way to running the Fig. 1 an interrupted vacuum zone, ie two separate vacuum zones is or are present in the bearing pedestal 6, but which are shown in FIG Fig. 3 are not shown, and thereby the effect of the magnets 23 for aligning the base rods 10 in the desired defined rotational position before the cutting knife 16 is reached in the area between the two vacuum zones. Alternatively, it is basically also conceivable to combine the negative pressure and the attraction force generated by the magnets 23 or to dispense with the use of negative pressure and only apply the attraction force generated by the magnets 23 to hold the base rods 10 in the troughs 8 use. Permanent magnets can be used as magnets 23. Alternatively, however, it is also conceivable to design the magnets 23 as electromagnets, which are preferably individually controllable in order to allow the attraction force generated by the magnets 23 to act in a targeted manner only in a certain area upstream in front of the cutting knife 16 for the desired alignment in the defined rotational position .

Otherwise, the in Fig. 3 with the same reference numerals as in Fig. 1 The components specified in terms of their function and basic structure have the same reference numerals as in Fig. 1 marked components, so that to avoid repetition, refer to their description based on Fig. 1 is referred.

Finally, it should be noted that the definition of the desired defined rotary position can be different from case to case and can be selected in particular depending on the properties of the base rods 10 to be processed and their metal strips 10a and also depending on the desired sectional pattern. While for example Fig. 1 shows a radial alignment of the material strips 10a as a defined angle of rotation position, is shown in FIG Fig. 3 the defined angle of rotation position aligned tangentially.
