Description

Transport drum for the tobacco processing industry

Technical Field

The invention relates to a conveying roller in the tobacco processing industry.

The invention also relates to a machine for the tobacco processing industry, in particular a filter segment production machine, for producing rod-shaped articles for the tobacco processing industry, in particular multi-segment filters or heat-not-combustible products.

The invention further relates to a method for conveying rod-shaped articles of the tobacco processing industry, in particular multi-segment filters or heat-not-burn products.

Background

Transport drums are used in machines of the tobacco processing industry, in particular in filter tip tipping machines or machines for producing smoking products in the form of rods, such as heat-not-combustible products or electronic cigarettes, for transporting cigarettes, filter elements or components thereof.

The aforementioned transport of rod-shaped articles during the production of cigarettes, filter rods and filter cigarettes or so-called hot-burn or electronic cigarettes is generally carried out in modern tobacco processing machines by means of transport drums, the shell surface of which or the drum body of which is provided with recesses or pockets for receiving rod-shaped articles for the transverse axial transport of the rod-shaped articles (cigarettes, filter rods or plugs, filter cigarettes). The receiving pocket for the rod-shaped article has a pocket bottom in this case.

Rod-shaped articles of the tobacco processing industry are arranged behind one another in the receiving pockets, generally in rows and transversely to the axial direction, during transport.

It is also known in the prior art to provide a deflecting roller in a device for deflecting rod-shaped articles, in particular cigarettes, by means of which the rod-shaped articles are deflected. Devices of this type are used, for example, in cigarette makers or filter tipping machines. Filter cigarettes are produced in filter tipping machines as rod-shaped articles, wherein, for example, articles having a double length of use are produced and subsequently cut into single-length products (filter cigarettes) or articles by means of a cutting device. The filter cigarettes or rod-shaped articles with uniformly oriented filters are then further processed in a filter tip attachment machine, wherein the filter cigarettes conveyed in two rows are diverted by means of a diverting device such that the filter cigarettes in a row are diverted by 180 ° about a transverse axis extending perpendicularly to the longitudinal axis. The diverted filter cigarettes are in this case arranged in each case on a conveyor drum between two non-diverted filter cigarettes in the empty receiving pockets of the conveyor drum, so that after the diversion process a row of filter cigarettes is formed.

In order to divert filter cigarettes, so-called conical diverters are used in particular, wherein, for the diversion process, two rows of opposite filter cigarettes must be spread apart in the longitudinal direction on a spreading drum before the diversion, wherein, next to the row of filter cigarettes or rod-shaped articles are transferred onto a conical diverting drum on which the rod-shaped articles describe a conical trajectory in order to be then arranged next to between two non-diverted filter cigarettes on a conveying drum conveying the non-diverted rod-shaped articles.

Devices for diverting rod-shaped articles are disclosed, for example, in DE3445945A1, EP0627175B1 and DE19920760 A1. DE3445575A1 also describes a method for spacing apart and turning two coaxial cigarette length sections on a machine for tipping filters.

Disclosure of Invention

The object of the invention is to enable a simple diversion of a plurality of rows of rod-shaped articles on a conveying drum in a conveying system for conveying rod-shaped articles, wherein in particular rod-shaped articles having different format lengths are to be conveyed and diverted independently of their format.

This object is achieved by a transport drum of the tobacco processing industry, which has a, in particular cylindrical, drum body that is rotatable or rotationally driven about an axis of rotation, wherein two rows of receiving pockets for rod-shaped articles of the tobacco processing industry, which are arranged next to one another in the circumferential direction of the drum body, are provided, each arranged behind one another, wherein each row of receiving pockets is rotatable or rotatable about a rotational axis that is oriented radially with respect to the axis of rotation, preferably independently of one another, wherein each row of receiving pockets is movable or moved independently of one another, in particular by means of a movement link that is oriented parallel to the axis of rotation of the transport drum and is linearly movable and coupled to the respective receiving pocket, in particular when the transport drum is simultaneously rotated about the axis of rotation.

The invention is based on the idea that two rod-shaped articles, such as filter plugs, filter cigarettes, multi-segment filters or in particular multi-segment heat-not-combustible products, which are conveyed and arranged side by side in a receiving pocket in a conveying drum, are rotated or deflected during the conveyance on the conveying drum, wherein it is also possible at the same time to increase or decrease the longitudinal axial distance between two opposite head ends of two rows of rod-shaped articles when they are received on the conveying drum, compared to the mutually opposite head ends of two rows of rotated or deflected rod-shaped article pairs when they are handed over to a subsequent conveying drum. This achieves that the conveyed rod-shaped articles are deflected on the conveying rollers and spread apart from one another when delivering two rows of deflected articles onto the following conveying rollers. For this purpose, the axes of rotation of two rows of two receiving pockets arranged next to one another are oriented parallel to one another in order to move the rotatable receiving pockets of the transport drum, wherein the axes of rotation are oriented in the radial direction relative to the axis of rotation of the transport drum. In this case, it can be provided within the scope of the invention that the linearly movable movement links for receiving pockets, which are oriented parallel to the axis of rotation of the transport drum, are moved independently of one another or simultaneously.

In order to move the receiving pockets, a movement link is provided for each axis of rotation of the receiving pockets. The movements of the individual kinematic links can be performed not only synchronously but also asynchronously.

In a further development of the transport drum, a linearly movable movement link for the respective receiving pocket is provided, which is movable or moved by means of a reciprocating gate (hubkulise). The movement of the movement link and thus also the rotation of the receiving pocket about the axis of rotation is thus configured in a simple mechanical manner.

According to a further aspect, it is provided that the receiving pockets are arranged between the reciprocating sliding chutes for the two rows with respect to the rotational axis of the transport cylinder.

A refinement of the invention is furthermore characterized in that the kinematic links for two rows of two receiving pockets arranged side by side along the longitudinal extension of the transport cylinder have a different radial distance from the axis of rotation of the transport cylinder.

According to an advantageous embodiment, provision is also made in the transport drum for the reciprocating carriages to each have a curved path (Kurvenhub) for the moving connecting rods, wherein the respective curved paths of the reciprocating carriages are designed such that the moving connecting rods perform a simultaneous or temporally offset movement during the rotation of the drum body and/or the moving connecting rods perform a simultaneous or temporally offset reciprocating movement of the same or of different size during the rotation of the drum body. This allows a flexible turning and spreading of the rod-shaped articles of the two rows of rod-shaped articles. The rod-shaped articles are aligned transversely axially in two rows one behind the other and transferred in two rows onto the conveying drum before being transferred onto the conveying drum. After the rod-shaped articles have been rotated or deflected on the transport rollers, they are handed off from the transport rollers to the following transport rollers, which transport the deflected rod-shaped articles further in the form of two rows of rod-shaped articles arranged behind one another in the transverse direction.

In one embodiment of the transport drum, it can be provided within the scope of the invention that the rod-shaped articles of one row are rotated or deflected on the transport drum by providing corresponding reciprocating chutes, while the rod-shaped articles of the other row are not rotated. In this case, the movement link does not execute a linear movement, the respective reciprocating slotted link for the movement link being a flat circular track.

Furthermore, a design of the transport cylinder is characterized in that during a complete revolution of the cylinder body through 360 °, each row of receiving pockets is rotated through 180 ° from a starting position and, after reaching the 180 ° rotational position, is rotated back into the starting position again.

Furthermore, it is advantageously provided in the transport drum that the movement links are designed as toothed links, wherein the toothed links each interact with a drive gear shaft for receiving the pockets.

It is furthermore advantageously provided that the drive gear shaft of the receiving pocket is rotatable about the respective axis of rotation of the receiving pocket.

In particular, according to a further aspect, the drive gear shaft for receiving the recess is rotatably mounted by means of a ball bearing, in particular a groove ball bearing, and by means of a needle bearing, respectively.

In an embodiment of the transport cylinder, it is furthermore preferred that the movement link for receiving the pockets is loaded or loadable, respectively, by means of a compression spring, in particular with respect to a reciprocating slide for the movement link. This achieves a secure guidance of the moving connecting rod or its end cooperating with the reciprocating slotted link.

According to a further aspect it is advantageous that the respective motion links for a pair of driving gear shafts arranged adjacent to each other along the rotation axis of the transport drum are arranged on different sides of the driving gear shafts. A compact arrangement of the kinematic links is thereby achieved.

According to a further preferred aspect of the transport cylinder, it is provided that the receiving pockets arranged next to one another in the longitudinal extension of the transport cylinder are rotated or rotatable in the same direction upon rotation about their respective axes of rotation.

A refinement of the transport drum is further characterized in that the movement links for a pair of receiving pockets arranged side by side along the longitudinal extension of the transport drum are movable or moved independently of one another, preferably by means of respective reciprocating chutes.

In a further embodiment of the transport drum, it is provided that the individual receiving pockets in each row or the plurality of receiving pockets in each row are each formed on a segment body which is rotatable about an axis of rotation. Depending on the design, the segment body can have not only one receiving pocket for a rod-shaped article, but also a plurality of receiving pockets for a rod-shaped article in each case in a different design. If the segment body is provided with a plurality of receiving pockets, these are oriented parallel to one another on the segment body. During the rotation of the transport drum, the respective segment body is thereby rotated or deflected about the respective axis of rotation together with the rod-shaped articles.

In particular, in one embodiment of the transport cylinder, it is provided that the receiving pockets are arranged on the respective segment bodies such that their central longitudinal axes extend beyond the rotational axis of the segment bodies. This makes it possible for the rod-shaped articles to be deflected on the conveying drum and at the same time spread apart from one another in the longitudinal axial direction during the transport of the rod-shaped articles and when the segment bodies are rotated about the axis of rotation.

In particular the transport drum is configured as a deflection-expansion drum.

The object is also achieved by a machine for the tobacco processing industry, in particular a filter segment maker, for producing rod-shaped articles of the tobacco processing industry, in particular multi-segment filters or heat-not-burn products, which is designed with a transport drum according to the invention as described above. Explicit reference is made to the above embodiments in order to avoid repetition.

The object is also achieved by a method for conveying rod-shaped articles of the tobacco processing industry, in particular multi-segment filters or heat-noncombustible articles, wherein a pair of rod-shaped articles arranged coaxially with one another along a conveying path is conveyed on a first conveying means, in particular a conveying drum, laterally and axially in two rows formed by rod-shaped articles arranged behind one another in the lateral direction, wherein the two rows of rod-shaped articles are transferred from the first conveying means onto the conveying drum according to the invention, wherein during the conveyance of the rod-shaped articles on the conveying drum the rod-shaped articles are each rotated through 180 ° and after their rotation are transferred onto a second conveying means, in particular a second conveying drum, wherein during the conveyance of the rod-shaped articles on the conveying drum and after the rotation through 180 ° the rod-shaped articles are arranged together and the ends of the two rows of rod-shaped articles opposite to one another are arranged at a smaller or greater longitudinal axial distance from one another. The method is carried out using the transport drum described above. Explicit reference is made to the above embodiments in order to avoid repetition.

In the drawings, elements and/or portions of the same or similar form are provided with the same reference numerals, respectively, and thus need not be re-described separately.

Detailed Description

In fig. 1 a turning-unwinding drum 10 according to the present invention is schematically shown in a perspective view. The deflection-expansion drum 10 is part of a machine for producing rod-shaped articles of the tobacco processing industry, for example, multi-segment filters or rod-shaped heat-noncombustible products. The deflecting/spreading drum 10 can also be a component of a conveyor system for rod-shaped articles, for example a filter tipping machine.

The deflecting-unrolling cylinder 10 has an outer cylindrical cylinder body 12 which is driven in rotation about a rotational axis R by means of a drive, for example a separate drive. On the outer side of the drum body 12, article segments 14.1, 14.2 are arranged one behind the other in the circumferential direction in two rows R1, R2. The article sections 14.1, 14.2 each have a receiving

pocket

141, 142 on their outer side, which is spaced apart and can be acted upon by underpressure. The rod-shaped articles are arranged in the receiving

pockets

141, 142 when passing from a conveying drum arranged upstream in the conveying direction of the rod-shaped articles. In this case, rod-shaped articles, for example, multi-segment filters, are conveyed in two rows from an upstream conveying drum in two rows, side by side and in each case arranged one behind the other in the transverse direction.

The article segments 14.1 form a row R1 of article segments 14.1 arranged one behind the other in the circumferential direction of the turn-and-unwind drum 10. Article segments 14.2, which each extend in the longitudinal direction of the turn-and-unwind drum 10 and are arranged beside the article segments 14.1 of the row R1, form a second row R2 of article segments 14.2. The article segments 14.1, 14.2 of the rows R1, R2 are rotatable about axes of rotation 24.1, 24.2, respectively. The respective axes of rotation 24.1, 24.2 of the article sections 14.1 and 14.2 are indicated in fig. 1 by dashed lines. The axes of rotation 24.1, 24.2 of the article segments 14.1, 14.2 are in this case oriented radially outward with respect to the axis of rotation R of the deflecting-spreading drum 10, wherein the respective axes of rotation 24.1, 24.2 extend beyond the central longitudinal axis of the receiving

pockets

141 or 142 of the article segments 14.1, 14.2. That is to say that the axes of rotation 24.1, 24.2 of the respective article segments 14.1, 14.2 are supported eccentrically.

After the rod-shaped articles arranged behind one another in the transverse direction are received in the receiving

pockets

141, 142 of the two rows R1, R2 of article segments 14.1, 14.2, the article segments 14.1, 14.2 are moved outwardly in opposite directions to one another, that is to say away from one another, so that the received rod-shaped articles are deflected when the drum body 12 is simultaneously rotated.

After the article segments 14.1, 14.2 or the rod-shaped articles arranged thereon have been turned through 180 ° on the turning/spreading drum 10, the distance between the head ends of the turned rod-shaped articles facing one another is greater than the longitudinal axial distance between the head ends facing one another during or after the rod-shaped articles are received in the receiving

pockets

141, 142. During the rotation of the drum body 12, the spreading out or longitudinal axial spacing of the received rod-shaped articles is therefore also carried out due to the simultaneous rotation of the article segments 14.1, 14.2 about the respective axes of rotation 24.1, 24.2. After the article segments 14.1, 14.2 have been turned through 180 °, the turned rod-shaped articles are arranged on the turning/spreading drum 10 in two rows transversely axially one behind the other, so that the turned and transversely arranged rod-shaped articles are transferred from the receiving

pockets

141, 142 of the article segments 14.1, 14.2 into the following conveyor drum and its receiving pockets in two rows, so that the rod-shaped articles turned and transferred on the following conveyor drum and longitudinally spread or spaced apart transversely axially are conveyed on the following conveyor drum.

The configuration of the drive for rotating the two rows R1, R2 of article segments 14.1, 14.2 is schematically shown in fig. 2. The description of the other elements of the turn-and-unwind drum 10 is omitted for the sake of clarity.

Two positive cams (Stirnkurven) 16.1, 16.2 spaced apart from one another are formed in the interior of the drum body 12 of the deflecting-spreading drum 10. The positive cams 16.1, 16.2 are arranged in this case in a stationary manner relative to the rotationally driven drum body 12 in the interior of the deflection-expansion drum 10.

The positive cams 16.1, 16.2 each have a cam runner (Kurvenkulissen) 17.1, 17.2, which cooperates with a cam pulley (kurvenrolen) 18.1, 18.2, which cooperates with a toothed connecting rod 20.1, 20.2. The toothed links 20.1, 20.2 are in this case oriented parallel to the axis of rotation R of the deflecting-spreading drum 10 and can be moved linearly independently of one another by means of the cam runners 17.1, 17.2. The individual toothed connecting rods 20.1, 20.2 are formed with toothing on the end faces, which engage in a toothed shaft of a driving gear shaft (Ritzelwellen) 22.1, 22.2. The drive gear shafts 22.1, 22.2 are connected at the outer side to the two rows R1, R2 of article segments 14.1, 14.2, respectively. By means of the linear movement of the toothed links 20.1, 20.2, the pinion shafts 22.1, 22.2 are each rotatable about a radially oriented axis of rotation 24.1, 24.2.

In the embodiment of fig. 2, the toothed connecting rod 20.1 engages the drive gear shaft 24.1 from the rear, while the toothed connecting rod 20.2 engages the drive gear shaft 22.2 from the front. The radial distance of the toothed link 20.1 from the axis of rotation R is smaller than the radial distance of the horizontally oriented toothed link 20.2 from the axis of rotation R. The toothed links 20.1, 20.2 can in this case move linearly parallel to the axis of rotation R. A drive for rotating the article segments 14.1, 14.2 is provided by the rolling of the cam pulleys 18.1, 18.2 connected with the toothed links 20.1, 20.2 on the respective cam runners 17.1, 17.2 of the positive cams 16.1, 16.2. When the drum body 12 rotates, the toothed links 20.1, 20.2 connected thereto execute a reciprocating movement on the basis of the positive cams 16.1, 16.2, respectively.

The cam pulleys 18.1, 18.2 are fastened to the toothed links 20.1, 20.2 and are pressed outward via compression springs 26.1, 26.2, respectively, towards the respective cam runners 17.1, 17.2. The cam pulleys 18.1, 18.2 thereby follow the respective cam tracks 17.1, 17.2 of the positive cams 16.1, 16.2. The toothed links 20.1, 20.2 of the movement links configured for the article sections 14.1, 14.2 or their receiving

pockets

141, 142 are also embedded in the drive gear shafts 22.1, 22.2 for the article sections 14.1, 14.2. During the rotation of the drum body 12, the toothed links 20.1, 20.2 perform a linear reciprocating movement along the rotation axis R independently of one another, so that the drive gear shafts 22.1, 22.2 cooperating therewith in each case are set into rotation about the respective rotation axis 24.1, 24.2 by the reciprocating movement of the toothed links 20.1, 20.2. The article segments 14.1, 14.2 are rigidly connected to the respective drive gear shaft 22.1, 22.2. As a result, a pivoting or rotational movement of the article segments 14.1, 14.2 about the rotational axis 24.1 or 24.2 is carried out when the drive gear shaft 22.1 or 22.2 rotates.

The rotation of the drive gear shaft 22.1 or 22.2 about the respective axis of rotation 24.1 or 24.2 by 180 ° is achieved in that the stroke length (Hubl ä nge) of the respective toothed link 20.1, 20.2 is half the drive gear circumference of the drive gear shaft 22.1 or 22.2 cooperating with the toothed link 20.1, 20.2, respectively.

During or during the transfer of the rod-shaped articles from the preceding conveying drum into the receiving pockets of the article segments 14.1, 14.2 or to the following conveying drum, the slope of the cam runners 17.1, 17.2 is zero. After the bar-shaped articles are delivered to the subsequent conveying rollers, the article segments 14.1, 14.2 are each pivoted back. The toothed links 26.1, 26.2 are pressed against the cam link 17.1, 17.2 by the spring force of the compression springs 26.1, 26.2.

The cam carriages 17.1, 17.2 of the positive cams 16.1, 16.2 are configured such that the curved course or the reciprocating movement of the toothed links 20.1, 20.2 takes place in the same direction in order to produce a same-direction pivoting direction of the drive gear shafts 22.1 or 22.2 or of the article segments 14.1, 14.2 connected thereto, which co-operate on the basis of the reciprocating movement of the toothed links 20.1, 20.2.

Fig. 3 shows a section of a cross section of the drive gear shaft 22.1 of the deflection-expansion drum 10. The drive gear shaft 22.1 is rotatably supported in the drum body 12 by means of a groove ball bearing 28, which is designed as a fixed bearing, and a needle bearing 30, which is designed as a floating bearing. In order to prevent dust from entering, for example, corresponding shaft seals 32 are provided on the underside and the top side of the drive gear shaft 22.1.

In the drive gear shaft 22.2 shown in fig. 3, the toothed link 20.2 engages in the drive gear shaft 22.2. The second toothed connecting rod 20.1 for the adjacent drive gear shaft 22.1 does not engage with the drive gear shaft 22.2, but rather with the drive gear shaft 22.1, which is not shown here.

As can be seen from fig. 3, the toothed links 20.1, 20.2 are arranged at a different radial distance from the axis of rotation R with respect to the axis of rotation R. The direction of movement of the toothed links 20.1, 20.2 is in this case perpendicular to the plane of the drawing. The drive gear shaft 22.1 or 22.2 is hollow on the inside, so that within the conveying region, the drive gear shaft 22.1 or 22.2 can be acted upon by a vacuum, wherein the vacuum is applied in the receiving

pockets

141, 142 of the product sections 14.1, 14.2, respectively. Thereby holding the rod-shaped articles in the receiving

pockets

141, 142 of the article sections 14.1 or 14.2.

When the diverted rod-shaped articles are delivered to the subsequent conveying drum, the underpressure in the receiving

pockets

141, 142 of the article sections 14.1, 14.2 is cut off.

All mentioned features, including features taken alone from the drawings and individual features disclosed in combination with other features, are considered essential to the invention, both alone and in combination. Embodiments in accordance with the present invention may be implemented by a single feature or a combination of features.
