Description

Rolling of rod-shaped articles of the tobacco processing industry

Technical Field

The invention relates to a method for wrapping rod-shaped articles of the tobacco processing industry, in particular filter cigarettes or filter rods or multi-segment filters. The invention also relates to a machine of the tobacco processing industry, in particular a cigarette manufacturing machine or a multi-segment filter manufacturing machine.

The invention further relates to a method for wrapping rod-shaped articles of the tobacco processing industry, in particular filter cigarettes or filter rods or multi-segment filters.

Background

In a filter attachment machine (filtertransetzmaschen), in particular a double-length filter plug or mouth segment, respectively, is placed between the cut and longitudinally axially spaced tobacco rods, wherein the glued connecting sheet (or connecting leaflet, i.e. verindlingsbl ä ttchen) and the smoking article components tobacco rods, filter plugs and tobacco rods are then attached to the assembled group of smoking articles.

The method and the device of the above type are used in particular for the mass production of filter cigarettes which are transported axially transversely on a filter attachment machine. The efficiency of the filter cigarette with regard to the items produced and discharged per unit time increases over time in a stepwise manner or must be adapted to the increased throughput of the upstream cigarette making machine (Zigarettenstrangmaschine).

DE 39 18 137 C1 describes a coated paper unit in a filter attachment machine. The glued coated paper is fed here as an endless strip of coated paper and is cut into individual or connected sheets by means of a cutting device. After cutting, the connecting sheets are separated by a gap and brought to the transport speed of the smoking article. After cutting and separation (pulling apart from each other), the now existing coated paper sheet is held by suction rollers and transported at a speed which remains the same, above the paper running speed of the endless coated paper strip.

Devices for rolling rod-shaped objects are known from the prior art. Thus, for example, DE 37 02 915 C2 shows a device for wrapping a glued connecting sheet around a butt point (Sto beta stalten) of a group formed by a rod-shaped tobacco item and a filter plug or a mouth segment. In this device, a rolling conveyor with a rolling surface and an associated stationary counter-rolling surface are provided, wherein the rolling surface and the counter-rolling surface form a rolling channel for the winding of the group with the connecting web material and are movable relative to one another. In this known device, the stationary counter-roller surface is associated with a moving web, which follows the direction of movement of the roller surface of the roller conveyor at a low speed while gripping the group in frictional engagement, before the group enters the roller channel. The article thus acquires a negative acceleration, so that it is already in the roll before it enters the roller channel. This pre-acceleration leads to a reduction of the negative acceleration acting on the object upon entering the rolling channel and thus to a greater protection of the rod-shaped object to be rolled.

Another device for rolling rod-shaped objects is known from EP 0 687 B1. A device is disclosed in which the circumferential partial rolling surfaces, the speed of which is controlled, are provided with an actuating bar each, which partial rolling surfaces interact with the stationary rolling surface without actuating bars.

Disclosure of Invention

The aim of the invention is to enable rod-shaped articles, in particular filter cigarettes or multi-segment filters, to be reliably wrapped with a particularly thick paper coating.

The invention is achieved by a device for wrapping rod-shaped articles of the tobacco processing industry, in particular filter cigarettes or filter rods or multi-segment filters, by means of a wrapping strip of limited length, with a conveyor drum for conveying the rod-shaped articles laterally and axially, wherein the conveyor drum has receiving pockets for receiving the rod-shaped articles and the receiving pockets are arranged one behind the other in the circumferential direction of the conveyor drum, wherein the conveyor drum is driven or driven in rotation about an axis of rotation, wherein a rolling belt conveyor for the rod-shaped articles with a rolling belt is arranged at the conveyor drum, wherein the rolling belt conveyor is designed such that, in an initial position in which no rod-shaped articles are arranged in the receiving pockets, in particular in the region of the rolling belt conveyor, the rolling belt and a plurality of receiving pockets arranged opposite the rolling belt are brought into mutual contact, and in a working position in which rod-shaped articles are arranged in the receiving pockets of the conveyor drum and are conveyed by the rotation of the conveyor drum, the rolling belt is designed or designed between the receiving pockets of the conveyor drum and the rolling belt conveyor belt, wherein the rolling belt is in the working position the rolling belt and the rolling belt is designed in the rolling belt conveyor path.

The invention is based on the idea that by providing a rolling belt conveyor interacting with the conveying rollers, it is also possible to use thicker material for enveloping the strip or for coating the strip of paper and to completely enclose the rod-shaped articles in the rolling channel by means of the rolling belt conveyor. In this way, for example, wrapping is completely achieved when wrapping the rod-shaped article, so that after wrapping of the rod-shaped article, the flag (F ä hnchen) wrapping the strip or the like does not protrude from the product or article in the region of the overlapping seam. By providing the rolling belt conveyor with a rolling belt, the pressing force on the wrapping strip or the rod-shaped articles to be wrapped in the roller channel can be specifically influenced or adjusted according to the thickness of the wrapping strip to be processed.

According to the invention, in the rest position of the device (in which no rod-shaped articles are conveyed or wrapped in the rolling channel), the rolling belt is brought into abutment with the receiving pockets of the conveying rollers arranged or located in the rolling channel. When the production of the device or machine is started, first rod-shaped articles, to which one wrapping strip each, for example a wrapping paper strip, is attached as a flag with a free end such that, for example, both or one free end of the wrapping strip protrudes from the rod-shaped article, are continuously introduced into the rolling channel, so that the rolling channel between the rolling belt and the conveying drum is opened by introducing the first rod-shaped articles into the rolling channel and the rod-shaped articles are thereby put into rotation about their longitudinal axis due to the counter pressure by the rolling belt and at the same time the attached wrapping paper sheet or the attached wrapping strip is placed and pressed onto the respective rod-shaped article.

By means of the transported rolling belt, it is achieved that the rod-shaped articles are completely wrapped with the wrapping tape, wherein by means of the rolling belt a pressing force is additionally exerted on the respective rod-shaped articles and the end of the wrapping tape at the wrapping end, whereby a firm adhesion of the wrapping end of the wrapping tape is achieved. Thus, full adhesion is also achieved in thicker encapsulated strips.

The device is further designed such that in the operating position the rolling belt is transported or transportable at a speed greater than one or the transport speed of the transport roller and/or in the operating position the rolling belt has the same transport direction along the rolling path as the transport roller. This achieves that a differential speed is formed between the rolling belt being conveyed and the conveying rollers rotating on themselves, wherein the rod-shaped articles are accelerated in the rolling channel due to the greater speed of the rolling belt relative to the conveying speed of the conveying rollers and are therefore conveyed in the direction of the conveying direction to the conveying section, in particular the conveying section, in front of the conveying rollers (vorauseilende) and/or the front receiving pockets on the conveying rollers. The rolling belt preferably moves along the rolling channel in the same conveying direction as the rotationally driven conveying drum. The rolling belt is conveyed at a conveying speed or an overspeed, which is, for example, 1.1 times the conveying speed of the conveying roller.

In a further development of the device, it is preferred that the rolling belt is guided on at least two rollers, wherein at least one of the rollers is drivable or driven by means of a drive which is controllable or adjustable in particular. In particular, a rolling flexible rolling belt is guided along the circumference of the transport drum between two rollers, wherein in particular one of these rollers is driven such that the rolling belt has the same transport direction as the transport direction of the transport drum in the region of the rolling channel.

According to a further aspect, in the device it is preferred that the rolling belt is tensioned or tensioned by means of a tensioning roller and/or that the rolling belt is adjustable or regulated in its position at the transport drum by means of a positioning regulating unit, wherein the positioning regulating unit has in particular tiltable rollers and/or rolling belt position detection sensors. The rolling belt is held under tension by a tensioning roller in contact with the flexible rolling belt. In one embodiment, it can be provided that the tensioning roller is adjusted in its position, for example by means of an actuating device or a motor, whereby the tensioning of the rolling belt is adjusted, in particular controlled or regulated, as a function of the position of the tensioning roller acting on the rolling belt. Furthermore, in one embodiment, the rolling belt can be tensioned or tensioned by means of an elastomer or the like. With the aid of the positioning adjustment unit for the rolling belt, it is possible for the rolling belt to be held in its position during operation of the device relative to the rod-shaped articles arranged in the receiving pockets of the conveying drum. For this purpose, the positioning adjustment unit is, for example, configured with a tiltable or pivotable deflecting roller for the rolling belt, wherein the rolling belt is moved into the respective position by tilting or pivoting the deflecting roller when the theoretical position is exceeded. To this end, in one embodiment, the positioning and adjusting unit is designed with a roller belt position detection sensor in order to detect the actual position of the roller belt in the operating position relative to the rod-shaped articles conveyed in the receiving pockets of the conveying drum. By means of an adjusting unit, to which the signal of the rolling-strip position detection sensor is transmitted, the rolling strip is aligned in its position by means of tiltable or pivotable rollers when the detected actual position of the rolling strip deviates from or exceeds a predetermined theoretical position.

In this device, it is also preferred that the receiving pockets of the conveying drum each have two rotatably mounted support rods for the rod-shaped articles, wherein the support rods are aligned, in particular, parallel to one another and/or are arranged parallel to the axis of rotation of the conveying drum. Thereby, the receiving cavity is provided with two support bars for the rod-shaped article, wherein the support bars and the rod-shaped article are brought into contact such that the rod-shaped article is in contact with the outer sides of the support bars. In the context of the present invention, it may be provided that the support rod is driven in rotation by means of a drive. In addition, in a further embodiment, it can be provided that the support bars are configured to run together, so that during or after the introduction of the rod-shaped articles with the attached wrapping strip into the roller channel, the rod-shaped articles rotating about their longitudinal axis are set into rotation by the relatively fast running rolling belt, wherein the rod-shaped articles are in this case always in contact with the running support bars. The enclosed rod-shaped articles are left in the accommodation cavities after passing through the rolling channels. In a further embodiment, it can additionally be provided that the support rod is additionally set in rotation by the drive when the rod-shaped articles are introduced into the rolling channel.

In addition, a further embodiment of the device is characterized in that the conveying drum has a plurality of conveying sections, in particular conveying segments, for the rod-shaped articles, which are arranged one behind the other in the circumferential direction, wherein the conveying sections, in particular the conveying segments, are designed with at least one rolling surface and at least one receiving pocket for the rod-shaped articles. In one embodiment, the transport section of the transport drum is designed as a transport segment. The conveying section is preferably configured as a rigid conveying section and has at least one receiving pocket for the rod-shaped articles.

If the conveying sections, in particular the conveying segments, are introduced into the rolling channel with the rotation of the conveying rollers, the rod-shaped articles introduced into the rolling channel are set in rotation by means of a relatively fast rolling belt acting on the rod-shaped articles, which roll on the rolling surfaces of the conveying sections, in particular the conveying segments. Preferably, the rolling surface for the rod-shaped articles is configured downstream of the receiving pockets with respect to the conveying direction of the conveying section, in particular of the conveying segments. If a plurality of receiving pockets are formed in the conveying sections, in particular in the conveying segments, it can be provided within the scope of the invention that a second receiving pocket for the rear (nanocoilend) of the rod-shaped articles is provided in order to receive the surrounding rod-shaped articles of the rear conveying section, in particular of the conveying segment.

In one embodiment of the device, it is furthermore advantageous if at least one rolling surface or a plurality of rolling surfaces of the conveying sections, in particular of the conveying segments, are designed with radially outwardly projecting spacers for attaching the wrapping strip to the rod-shaped articles. By means of the radially outwardly projecting spacer of the conveying drum for the wrapping strip attached to the rod-shaped articles, the free, in particular rear, section of the wrapping strip is spaced apart or kept away from the rolling surface or rolling surfaces of the conveying section, so that the free sections of the wrapping strip do not touch the rolling surface or rolling surfaces. The wrapping strip or the rear end of the wrapping strip is here attached to the rod-shaped article before it is rolled around with the respective wrapping strip, depending on the type of flag or the like. Preferably, the respective front ends of the enclosing strips are placed or attached at the respective rod-shaped articles.

In particular, according to a further aspect of the device, at least one rolling surface or a plurality of rolling surfaces of the transport section, in particular of the transport segment, is/are formed between two receiving pockets which are formed one after the other in the circumferential direction of the transport drum.

In addition, a configuration of the device is characterized in that the receiving pockets each have at least one pocket boundary, wherein the at least one pocket boundary of the receiving pocket in the operating position of the rolling belt conveyor is arranged to be rolled over by rod-shaped articles rolling in the roller channel. The receiving pockets are preferably designed as flat pockets on the conveying sections, in particular on the conveying sections.

In one embodiment of the device, it is provided that the conveying sections, in particular the conveying segments, each have two receiving pockets, wherein in particular the front receiving pocket in the conveying direction of the conveying drum is provided for receiving the rod-shaped articles to be wrapped in the rolling channel, and the rear receiving pocket in the conveying direction of the conveying drum is provided for the wrapped rod-shaped articles, which are arranged in the rear conveying section, in particular the receiving pocket of the conveying segment, before they are wrapped around and are displaced in the rolling channel in the direction of the front conveying section, in particular the conveying segment.

Furthermore, according to a further aspect, the device is characterized in that, upstream of the rolling belt conveyor with respect to the conveying direction of the conveying drum, rollers, in particular suction rollers of a coating device, are arranged for attaching the wrapping strip to the rod-shaped articles arranged on the conveying drum. The wrapping strip is attached to the rod-shaped article by means of rollers, wherein in one embodiment it is provided that the rollers or suction rollers are arranged such that one end of the wrapping strip is placed on the rod-shaped article and the rear free end of the wrapping strip is arranged as a flag on the rod-shaped article as a type of free end. For this purpose, for example, the rollers or suction rollers have one or more respective recesses into which the rod-shaped articles to be provided with the wrapping strip are introduced for a short time in order to place one end of the wrapping strip at the respective article. The wrapping strip is attached to the rod-shaped articles from above, i.e. on the side of the rod-shaped articles facing away from the conveyor drum.

In a development of the device, preferably, upstream of the rollers, in particular the suction rollers, with respect to the conveying direction of the conveying drum, an article supply device for supplying rod-shaped articles to the conveying drum is arranged at the conveying drum. A compact construction is achieved by the preferred arrangement of the article supply device, in particular the supply drum or the conveyor assembly, by means of which the rod-shaped articles are supplied to and transferred to the conveyor drum, and the arrangement of the rollers, in particular the suction rollers, behind the article supply device with respect to the transverse axial conveying direction of the rod-shaped articles for supplying and attaching the wrapping strip to the rod-shaped articles conveyed transversely axially on the conveyor drum. The rod-shaped articles are preferably conveyed laterally and axially by means of an article feed device, in particular a feed drum or a conveyor assembly.

In addition, a development of the device is characterized in that the rollers, in particular the suction rollers, have transport sections for the wrapping strip which are arranged one behind the other in the circumferential direction of the rollers, wherein in particular the transport sections each have a recess. On the conveying section of the rollers, in particular suction rollers, for feeding and attaching the wrapping strip, a finite length of wrapping strip is arranged or arranged and attached or attached from above to the rod-shaped articles. In one embodiment, the conveyor segment of the roller, in particular of the suction roller, has a cavity, so that when the wrapping strip placed on the conveyor segment is attached to the rod-shaped articles, the rod-shaped articles engage partially into the cavity and the wrapping strip is attached to the articles by means of a planar contact surface. Within the scope of the present disclosure, the suction rollers described herein are considered as independent inventive subject matter.

In a further development of the device, it is preferred that a roller shoe for guiding the rolling belt is arranged between two rollers of the rolling belt conveyor, on which rollers the rolling belt is guided along a peripheral portion of the conveying roller. This achieves a reliable guidance of the rolling belt in the rolling channel between the input-side roller and the output-side roller in the operating position of the rolling belt.

In one embodiment of the device, it is furthermore advantageous if, downstream of the conveying rollers with respect to the conveying direction of the rod-shaped articles, second conveying rollers are provided for the transverse axial conveyance of the rod-shaped articles, wherein the second conveying rollers have receiving pockets for receiving the rod-shaped articles and the receiving pockets are arranged one behind the other in the circumferential direction of the second conveying rollers, wherein the second conveying rollers are driven or driven in rotation about an axis of rotation, wherein a rolling belt conveyor for the rod-shaped articles with a rolling belt is arranged on the second conveying rollers, wherein the rolling belt conveyor, which is arranged in particular at the second conveying rollers, is designed such that, in an initial position in which no rod-shaped articles are arranged in the receiving pockets, in particular in the region of the rolling belt conveyor, the rolling belt and a plurality of receiving pockets arranged opposite the rolling belt are brought into contact with one another, and, in an operating position in which the rod-shaped articles are arranged in the receiving pockets of the second conveying rollers and are conveyed by rotation of the second conveying rollers, the rolling belt conveyor is designed or designed such that, in the operating position, the rolling belt conveyor and the operating position, the rolling belt conveyor, the operating channel of the rolling belt conveyor and the article are arranged in the operating position. In this embodiment, it is provided that rod-shaped articles which are rolled between the first conveyor roller and the first rolling belt conveyor arranged there or are wrapped around by the wrapping strip inside the first rolling channel are transferred to the second conveyor roller from the first conveyor roller on which the first rolling belt conveyor is arranged to the second conveyor roller on which the second rolling belt conveyor is arranged. After this, the respective outer end of the wrapping strip is pressed against the rod-shaped articles in a second rolling channel between the second conveyor roller and a second rolling belt conveyor arranged there. This is accomplished in the roller channel by pressing the rolling band onto the wrapping band that has been wrapped around the rod-shaped article.

The device comprises a combination of a first conveyor roller and an immediately following second conveyor roller, at which a rolling belt conveyor is formed in each case for forming a rolling channel between the respective rolling belt conveyor and the respective associated conveyor roller. In this case, the rod-shaped articles wrapped by the wrapping band in the first rolling channel are transferred from the first conveyor roller to the second conveyor roller. Next to this, the transferred rod-shaped articles are fed into the second rolling channel to cause a complete winding of the wrapping strip at the respective rod-shaped articles in the second rolling channel. By using or constructing two rolling channels it is possible to also attach a thicker wrapping strip at the rod-shaped article and wrap the wrapping strip completely, i.e. without the flag or the like protruding, around the rod-shaped article. It is thus possible, for example, to also provide mechanically fragile or sensitive rod-shaped articles with thicker enveloping strips.

The invention therefore comprises a device for wrapping rod-shaped articles of the tobacco processing industry, in particular filter cigarettes or filter rods or multi-segment filters, by means of a wrapping strip of limited length, with a first conveyor drum for conveying the rod-shaped articles laterally and axially, wherein the first conveyor drum has receiving pockets for receiving the rod-shaped articles and the receiving pockets are arranged one behind the other in the circumferential direction of the first conveyor drum, wherein the first conveyor drum is driven or driven in rotation about an axis of rotation, wherein one, in particular a first, rolling belt conveyor for the rod-shaped articles with a rolling belt is arranged at the first conveyor drum, and with a second conveyor drum, wherein a second conveyor drum is arranged behind the first conveyor drum with respect to the conveying direction of the rod-shaped articles for conveying the rod-shaped articles laterally and axially, wherein the second conveyor drum has receiving pockets for receiving the rod-shaped articles and the receiving pockets are arranged one behind the other in the circumferential direction of the second conveyor drum, wherein the second conveyor drum is driven or driven in rotation about the axis of rotation, wherein the one, in particular the second, rolling belt conveyor for the rod-shaped articles arranged at the second conveyor drum is arranged.

For this purpose, in one embodiment of the device it is advantageously provided that in the operating position the rolling belt of the rolling belt conveyor arranged at the second conveyor roller is conveyed or conveyable at a speed corresponding to or lower than a conveying speed of the second roller, or that in the operating position the rolling belt of the rolling belt conveyor arranged at the second conveyor roller is conveyed or conveyable at a speed lower than or lower than a conveying speed of the second conveyor roller.

In the case of a situation in which the rolling belts of the second rolling belt conveyor are conveyed at the same speed as the second conveying rollers (i.e. without a speed difference between the rolling belts and the conveying rollers) in the working position, the wound ends of the wrapping strip are pressed against the rod-shaped articles in the roller channel by means of the rolling belts. In this case, the rod-shaped articles in the rolling channel between the second rolling belt conveyor and the second conveying roller do not rotate about their central longitudinal axis, so that the rod-shaped articles are conveyed through the rolling channel in a stationary position.

In the other case (in the working position, the rolling belt of the second rolling belt conveyor is conveyed at a lower speed relative to the conveying speed of the second conveying rollers), the rod-shaped articles are moved counter to the conveying direction of the second conveying rollers, wherein the rod-shaped articles simultaneously roll about their central longitudinal axis. This makes it possible to close the possible opened winding of the wrapping strip by a further rolling process. In addition, a further displacement of the rod-shaped articles on the second conveyor roller takes place here.

According to a further aspect, the device is characterized in that the rolling belt of the rolling belt conveyor arranged at the second conveyor roller is guided on at least two rollers, wherein at least one of the rollers is drivable or driven by means of a drive which is in particular controllable or adjustable.

In one embodiment of the device, it is advantageously provided that the rolling belt of the rolling belt conveyor arranged at the second conveyor roller is tensioned or tensioned by means of a tensioning roller.

The device is further advantageously improved in that the second conveying drum has a plurality of conveying sections, in particular conveying segments, for the rod-shaped articles, which are arranged one behind the other in the circumferential direction, wherein the conveying sections, in particular the conveying segments, of the second conveying drum are configured with at least one rolling surface and at least one receiving pocket for the rod-shaped articles.

For this purpose, it is provided according to one embodiment that the conveying sections, in particular the conveying segments, of the second conveying drum each have two receiving pockets, wherein in particular the front receiving pocket in the conveying direction of the second conveying drum is provided for receiving rod-shaped articles transferred from the upstream arranged, in particular the first conveying drum, and the rear receiving pocket in the conveying direction of the second conveying drum is provided for receiving rod-shaped articles to be rolled or rolled in the rolling channel, which rod-shaped articles are arranged in the front receiving pocket of one front conveying section, in particular the conveying segment, before their rolling in the roller channel and are displaced in the direction of the rear conveying section, in particular the conveying segment, in the roller channel.

In addition, a development of the device is characterized in that between the two rollers of the rolling belt conveyor arranged at the second conveyor roller, a roller shoe for guiding the rolling belt is arranged, on which roller the rolling belt of the rolling belt conveyor arranged at the second conveyor roller is partially guided along the circumference of the second conveyor roller. Is guided reliably along the roller channel between the input-side roller and the output-side roller by means of a roller bearing, for example a roller belt.

The object is also achieved by a machine of the tobacco processing industry, in particular a cigarette making machine or a multi-segment filter making machine, which is configured with the device described above. To avoid repetition, explicit reference is made to the preceding description. The object is also achieved by a method for wrapping rod-shaped articles of the tobacco processing industry, in particular filter cigarettes or filter rods or multi-segment filters, using the device for wrapping rod-shaped articles described above. In this case, reference is made in full to the above statements.

In addition, one embodiment of the method is characterized in that the rod-shaped articles are accelerated in the rolling channel by means of a driven rolling belt of the rolling belt conveyor and/or are relocated on the transport rollers.

In a development of the method, it is also provided that, in the initial position, the rolling belt abuts against the receiving pockets of the conveying drum, and that the rolling channel is formed or formed between the rolling belt and the receiving pockets of the conveying drum when the rod-shaped articles are conveyed in the working position on the conveying drum. It is thereby achieved that, when the machine is started, the conveyed first rod-shaped article is also reliably wrapped in the rolling channel by the attached wrapping strip. At the end of the rolling channel, the completed or fully wrapped rod-shaped articles are conveyed out of the rolling channel and transferred from the conveyor drum to the subsequent conveyor drum.

In one embodiment of the method, it is furthermore provided that the rod-shaped articles are transferred from the conveying rollers to the subsequent, in particular second conveying rollers after a first wrap roller in a preferably first rolling channel between the in particular first conveying roller and the rolling belt conveyor arranged at the in particular first conveying roller, and that the transferred rod-shaped articles are decelerated and/or re-displaced in the second rolling channel between the second conveying roller and the rolling belt conveyor arranged at the second conveying roller by means of a driven rolling belt of the rolling belt conveyor arranged at the second conveying roller and the rolling belt conveyor arranged at the second conveying roller, or the rod-shaped articles are transferred from the conveying rollers to the subsequent, in particular second conveying roller after the first wrap roller in the preferably first rolling channel between the in particular first conveying roller and the rolling belt conveyor arranged at the in particular first conveying roller, and that the transferred articles are arranged between the second conveying roller and the second rolling belt conveyor arranged at the in the preferably first rolling channel between the second conveying roller and the second rolling belt conveyor arranged at the second conveying roller.

In accordance with a further aspect of the method, it is advantageous if, in the initial position, the rolling belt of the rolling belt conveyor arranged at the second conveyor roller rests against the receiving pockets of the second conveyor roller, and if, in the operating position on the second conveyor roller, the rod-shaped articles are conveyed, the rolling channel is formed or formed between the rolling belt of the rolling belt conveyor arranged at the second conveyor roller and the receiving pockets of the second conveyor roller.

Detailed Description

Within the scope of the present invention, features marked as "in particular" or "preferred" are to be understood as optional features.

In the figures, elements and/or parts of the same or identical type are provided with the same reference numerals, respectively, so that a renewed description is omitted, respectively.

Fig. 1 schematically shows a perspective view of a roller assembly T with a conveyor roller 10 and a rolling belt conveyor 20 arranged at the conveyor roller 10. A schematic cross-section of the roller assembly T is shown in an enlarged detailed view in the illustration of fig. 2.

The rolling belt conveyor 20 is arranged at the conveyor drum 10 in order to wrap around the rod-shaped articles 30 arranged thereon in co-action with the conveyor drum 10 for attachment to the wrapping strip 40 at the rod-shaped articles 30. On the transport drum 10, the rod-shaped articles 30 are transported in the transverse axial direction in the receiving pockets 12 (see fig. 2). The receiving pockets 12, in which the rod-shaped articles 30 are received, are formed on the conveying segments 14 or conveying sections of the conveying drum 10.

Upstream of the rolling belt conveyor 20, at the conveying drum 10, suction rollers 50 or coating rollers are arranged, by means of which the wrapping strip 40 is attached to the rod-shaped articles 30. The wrapping strip 40 is attached to the rod-shaped article 30 in such a way that the rear free end of the wrapping strip 40 protrudes from the rod-shaped article 30. The front end of the wrapping strip 40 is attached to the rod-shaped article 30.

As can be seen from fig. 2, the conveyor drum 10 has conveyor segments 14 arranged one behind the other in the circumferential direction, on which receiving pockets 12 are formed on the outside for the rod-shaped articles in each case. On both sides of the receiving pocket 12, rolling surfaces 16.1, 16.2 are formed on the outside at the conveying sections 14, so that the rod-shaped articles 30 roll in a rolling channel 25 formed between the rolling belt conveyor 20 and the conveying roller 10.

The suction roller 50 has segments 51 of the enveloping strip 40 for cutting in the circumferential direction, which are transferred to the rod-shaped articles 30 and attached thereto. The segments 51 of the suction rollers 50 each have a cavity 52 into which the rod-shaped articles move under the interaction of the synchronously rotating suction rollers 50 and the conveying drum 10 when the wrapping strip 40 is attached to the rod-shaped articles 30, whereby the front end of the attached, glued wrapping strip 40 is pressed onto the rod-shaped articles 30 from above by a surface-like contact, and the respective rear free end of the wrapping strip 40 is configured as a flag.

The conveyor segment 14 of the conveyor drum 10 has on the upper side a spacer 15, preferably in the form of a needle, projecting radially outwards for the rear free end of the attached wrapping strip 40, whereby contact of the rear free end with the surface of the conveyor segment 14 is avoided, since the rear free end rests on the spacer 15.

In fig. 3, a further illustration of the rolling channel 25 formed between the rolling belt conveyor 20 and the transport cylinder 10 is schematically shown. The rolling belt conveyor 20 has rollers 21 on the input side and rollers 22 on the output side. The roller belt 23 is guided over the

rollers

21, 22, so that a rolling channel 25 is formed by the section of the roller belt 23 guided between the

rollers

21 and 23 and by the conveyor drum 10, through which rolling channel 25 the rod-shaped articles 30 are conveyed through.

The

rollers

21, 22 for the rolling belt 23 are driven by means of a motor, wherein the rolling belt 23 is conveyed at a speed which is greater than the path speed of the adjacent conveying roller 10. Thus, when the rod-shaped articles 30 with the attached wrapping strips 40 are introduced or introduced, the respective rod-shaped articles 30 are accelerated in the rolling channel 25 and the rod-shaped articles 30 roll out of the receiving pockets 12 in the conveying direction, whereby the wrapping strips 40 are wound around the rod-shaped articles 30 in the rolling channel 25 with a rotation about their longitudinal axes. When the rod-shaped articles 30 enter the rolling channel 25, the underpressure respectively attached at the receiving pockets 12 is disconnected, so that the rod-shaped articles 30 are released for rolling in the rolling channel 25.

Before production at the drum assembly T (which is, for example, an integral part of a filter attachment machine or a multi-segment filter manufacturing machine) begins, there are no rod-shaped articles 30 in the receiving pockets 12 of the conveyor drum 10 and in the rolling channel 25. In this case, the rolling belt 23 rests on the outside of the conveyor drum 10 on the conveyor segments 14 in the rest position. During start-up and continuous operation of the machine or roller assembly T, rod-shaped articles 30 are introduced into the rolling channel 25, whereby the rolling channel 25 is formed between the conveyor roller 10 and a section of the rolling belt 23, which is conveyed between the roller 21 and the roller 22 on the output side. Thus, the rolling channel 25 is formed only when the rod-like articles 30 are introduced into the rolling channel 25 as production starts. The speed of the rolling belt 23 is determined here in such a way that the rod-shaped articles 30 to be wrapped by the attached wrapping strip are again arranged in the receiving pockets 12 of the preceding conveyor segments 14 at the end of the rolling channel 25. When the completely wrapped rod-shaped articles 30 exit the rolling channel 25, the underpressure in the receiving pockets 12 of the conveyor segments 14 is switched on again, so that the wrapped rod-shaped articles 30 are reliably conveyed further on the conveyor drum 10.

For tensioning the roller belt 23, the roller belt 23 is guided in the conveying direction between the roller 22 and the roller 21 on the tensioning roller 24. Within the scope of the invention, it can be provided that tensioning roller 24 is tensioned by means of a tensioning device, for example an elastomer or the like. It can be provided here that the tensioning of the rolling belt 23 is controlled by means of a control device (not shown here) or is regulated by means of a regulating device (not shown here).

The exemplary embodiment shown in fig. 4 differs from the exemplary embodiment shown in fig. 3 in that a rolling guide 26, for example in the form of a rolling hand, is arranged between the roller 21 and the roller 22 in the conveying direction of the rolling belt 23. A reliable guidance of the rolling strip 23 along the rolling channel 25 is thereby achieved. In a further embodiment, it can be provided that the roller guide 26 is heated, for example, by means of a heating cartridge (eizpatrone) or a heating device.

Fig. 5 schematically shows a perspective view of a transport section 14 for the transport drum 10 shown in fig. 1 to 4 according to a further embodiment.

The conveyor segment 14 has a receiving pocket 12, in which pocket 12 the rod-shaped articles 20 (without wrapping strip) are received by an upstream conveyor drum and are then provided with the wrapping strip 40 by means of suction rollers 50 (see fig. 2) arranged at the conveyor drum 10.

The conveying section 14 also has a front running surface 16.1 and a rear running surface 16.2 relative to the conveying direction of the conveying drum. During the rolling of the rod-shaped articles 30 in the rolling channel 25, the rod-shaped articles arranged in the receiving pockets 12 roll out of the receiving pockets 12 via the front rolling surface 16.1, thereby wrapping the attached wrapping strip 40 around the respective rod-shaped product 30. Furthermore, the conveyor segment 14 has a second receiving pocket 18 in which the completely rolled rod-shaped articles 30 (coming from the following conveyor segment and after rolling out on the following roll-out face 16.2) are arranged after their wrapping. The rod-shaped articles 30 are accommodated in the receiving pockets 18 by the subsequent conveying section of the conveying drum.

In order to hold the rod-like articles in the

accommodation cavities

12 or 18 outside the rolling channel 25, the

accommodation cavities

12 or 18 are each provided with a suction air hole or the like to which negative pressure is applied.

Furthermore, in the embodiment of the conveyor segment 10 not shown here, it is possible that the rolling surfaces 16.1 and/or the rolling surfaces 16.2 each have an outwardly projecting or protruding spacer for attaching to the free end of the wrapping strip of rod-shaped articles, whereby the adhesive-provided free end of the wrapping strip does not touch the rolling surfaces 16.1, 16.2.

Fig. 6 shows a further exemplary embodiment of the arrangement of the rolling-belt conveyor 20 at the conveying roller 10. An enlarged detailed view of the rolling belt conveyor 25 at the conveying drum 10 is shown in fig. 7.

The transport cylinder 10 has receiving pockets 120 in the circumferential direction, wherein the receiving pockets 120 are each formed by two supporting

bars

121, 122 aligned parallel to the rotational axis of the transport cylinder 10. The support bars 121, 122 are rotatably supported. The rolling belt conveyor 20 has a revolving, flexible rolling belt 23 guided over

rollers

21 and 22.

In the conveying direction of the rolling belt 23, a rolling channel 25 for the rod-shaped articles on the conveying drum 10 is formed between the roller 21 and the roller 22 in cooperation with the conveying drum 10. Here, the wrapping strip is attached at a free end (not shown here) to the rod-shaped article, wherein the wrapping strip is wrapped around the rod-shaped article within the rolling channel 25.

Since the

support rods

121, 122 are mounted in a rotating manner, the rod-shaped articles 30 are enclosed by the attached enclosing strip when they are introduced, by means of the active rolling belt 23, in a rotation in the rolling channel 25. Furthermore, a tensioning roller 27, to which a force is applied (resetting), is arranged between the roller 22 and the roller 21 in order to tension the rolling belt 23.

When the production of the machine is started, there are initially no rod-shaped articles in the rolling channel 25, so that the rolling strip 23, which is kept taut, rests on and is in contact with the supporting

bars

121, 122 arranged in the rolling channel 25. When the rod-shaped articles 30 are introduced into the rolling channel 25 by the rotation of the conveying roller 10, the rolling belt 23 is lifted by the introduced rod-shaped articles 30, thereby configuring the rolling channel 25.

For driving the rolling belt 23, the rollers 21 are connected by means of a drive (not shown here), whereby the rollers 21 are set in rotation to transport the rolling belt 23.

Fig. 8 schematically illustrates a drum assembly T according to another embodiment. The wrapping strip cut to length is attached to the rod-shaped articles on the transport drum 10 by means of the suction rollers 50. The suction roller 50 is preferably embodied with a recess in order to achieve a large surface for pressing with particularly small presses onto the rod-shaped articles, as a result of which the wrapping strip is reliably attached to the respective rod-shaped article.

The rod-shaped articles provided with the enveloping strip are then moved on the conveyor roller 10 in the direction of the first rolling-belt conveyor 20 or the (first) rolling channel 25 at the conveyor roller 10, wherein the rod-shaped articles are set in rotation between the rolling belt 23 of the rolling-belt conveyor 20 and the conveyor roller 10 in the rolling channel 25. The rod-shaped articles roll on the conveyor segments 14 of the conveyor drum 10. Preferably the transport section 14 is constructed according to the embodiment shown in fig. 5. The rolled rod-shaped articles are positioned in the receiving pockets 18 of the preceding conveyor segment at the end of the rolling channel 25 by means of the additional receiving pockets 18, wherein the winding end of the wrapping strip is aligned in a predetermined position at the exit of the rolling channel 25.

In the exemplary embodiment shown in fig. 8, the rolling belt 23 is guided between the input-side roller 21 and the output-side roller 28.

When the rod-shaped articles roll in the rolling channel 25, the rolling belt 23 is conveyed at a higher speed in a corresponding manner to the embodiment according to fig. 1 to 4, with respect to the conveying speed of the rod-shaped articles in the receiving pockets 12 (see fig. 5) of the conveying drum 10. By means of this particularly small, higher differential speed or overspeed of the rolling belt 23, the rod-shaped articles, for example assembled segment groups, are rolled forward from the pockets 12 (see fig. 5) in the conveying direction of the conveying drum 10, whereby the respective wrapping strips are wound around the rod-shaped articles.

In particular, the rod-shaped articles are wound in the rolling channel 25 in such a way that the wraparound in the receiving pocket 18 of the preceding conveyor segment 14 is in contact with the pocket surface in the pocket surface of the receiving pocket 18, so that, when the rod-shaped articles are transferred from the conveyor drum 10 to the subsequent conveyor drum 100, the wraparound of the rod-shaped articles is placed on the outside or above after the transfer to the conveyor drum 100.

Furthermore, a rolling belt conveyor 110 is arranged on the (second) conveyor roller 100 in order to produce rod-shaped articles arranged on the conveyor roller 100 with a completely closed wraparound. With the second rolling belt conveyor 110, it is possible to firmly adhere and press the wrapping tape or its wrapping end, which is not (initially) completely adhered and is not in contact with the rod-shaped articles, to the rod-shaped articles even in the case of thicker wrapping tapes.

The rolling belt conveyor 110 has rollers 111 on the input side and rollers 112 on the output side. The roller belt 113 is guided over the

rollers

111, 112, so that a roller channel 115 is formed by the section of the roller belt 113 guided between the

rollers

111 and 112 and by the transport drum 100, through which roller channel 115 the rod-shaped articles are transported. The roller belt 113 is conveyed from the roller 112 via a further, preferably driven roller 116 back to the roller 111 on the input side. Further, a tension roller 114 is disposed at the rolling belt 113 to tension the rolling belt 113.

After the transfer of the (partially or incompletely) wound rod-shaped articles from the (first) conveyor drum 10 to the subsequent (second) conveyor drum 100, the rod-shaped articles are arranged on the conveyor drum 100 in such a way that, for example, the open winding end of the wrapping strip is arranged above or outside on the conveyor drum 100. The rod-shaped articles are then fed into the rolling channel 115 with the winding end of the wrapping strip pointing outwards.

The transport speed of the rolling belt 113 is set such that, when the open winding end of the wrapping strip of rod-shaped articles comes into contact with the rolling belt 113, the rod-shaped articles in the rolling channel 115 do not move and thus a pressing action is exerted on the open, outer or outer winding end of the wrapping strip by means of the rolling belts 113 running in parallel or together, whereby the open winding end of the wrapping strip is completely connected to the rod-shaped articles. In this case, the conveying speed of the rolling belt 113 corresponds to the conveying speed of the rod-like article that does not move on the conveying roller 100.

In an alternative embodiment, it is possible for the roller belt 113 to be moved at a (differential) speed which is lower than the conveying speed of the rod-shaped articles on the conveying drum 100 before entering the roller channel 115. Since there is a (negative) speed difference between the rolling belt 113 and the conveying speed of the rod-shaped articles on the conveying drum 100 before entering the rolling channel 115, the rod-shaped articles in the rolling channel roll out of the receiving pockets of the conveying drum 100 counter to the conveying direction of the conveying drum 100, whereby the open winding end of the wrapping tape is closed by the further rolling process by means of the rolling belt conveyor 110. At the end of the rolling channel 115, rod-shaped articles rolling (backwards) in the rolling channel 115 are arranged in the pockets of the conveyor drum 100.

Fig. 9 schematically shows a further embodiment of a roller assembly T. The rolling belt conveyor 20 here additionally has, for the rolling belt 23 guided on the

rollers

21, 28, 22, tiltable or pivotable rollers 29, wherein the rolling belt 23 is moved in its position by tilting or pivoting the rollers 29 to the left or to the right, i.e. along the longitudinal axis of the rod-shaped articles 30, relative to the rod-shaped articles 30 conveyed on the conveyor drum 10, whereby the rolling belt 23 is precisely aligned or aligned for the rod-shaped articles 30 with the respectively attached wrapping strip 40 around the rollers. For this purpose, the rollers 29 are arranged on the roller assembly T by means of corresponding movable holders. For gluing or pivoting the rollers 29, the control unit (not shown here) is furthermore provided with a sensor for detecting the position of the rolling belt 23 in the roller belt conveyor 20, which sensor forwards a detection signal to a corresponding evaluation device. By means of an evaluation device which performs, in particular, a theoretical-actual-value comparison of the detection signals, for example by means of a drive, the holding portion for the roller 29 and thus the roller 29 are tilted or pivoted when a predetermined theoretical value is exceeded, in order to position the rolling belt 23 guided on the roller 29 in its initial orientation or in a predetermined orientation with respect to the rod-shaped articles 30 moving together with the rolling belt 23.

In order to keep the rolling belt 23 taut during operation of the rolling belt conveyor 20, the rolling belt conveyor 20 has a pivotally supported tensioning roller 127.

It can also be seen from fig. 9 that a suction roller 50 is provided upstream of the rolling belt conveyor 20 at the conveying drum 10, and a feed drum 60 is provided upstream of the suction roller 50 for feeding and transferring the rod-shaped articles 30 to the conveying drum 10.

All the mentioned features, also the features which can be taken alone from the drawings, and also the individual features disclosed in combination with other features, are considered to be essential to the invention both individually and in combination. Embodiments according to the present invention may be realized by any combination of individual features or a plurality of features.
