Description

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

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

In filter attachment machines, a filter plug or mouthpiece, in particular twice the length, is inserted between cut tobacco rods that are spaced apart along the longitudinal axis, with a glued connecting leaflet then being attached to an assembled smoking article group with the smoking article components tobacco rod, filter plug and tobacco rod.

Methods and devices of the type described above are used in particular for packaging filter cigarettes that are conveyed transversely axially on a filter tipping machine. Their performance in terms of the articles produced and output per unit of time has repeatedly increased by leaps and bounds over time or had to be adapted to the increased performance of the upstream cigarette rod machine.

In DE 39 18 137 C1 describes a tipping paper unit in a filter tipping machine. The glued tipping paper is fed in as an endless tipping paper strip and cut into individual sheets or connecting sheets by means of a cutting device. After the cut, these connecting leaves are separated by spacing them and brought to the conveying speed of the smoking articles. After cutting and separating (pulling apart), the covering paper sheets that have now been created are held by the suction roller and transported at a constant speed, which is above the paper running speed of the endless covering paper strip.

Devices for rolling rod-shaped objects are known from the prior art. For example, shows DE 37 02 915 C2 discloses a device for wrapping glued connecting sheets around the joints of groups formed from rod-shaped tobacco articles and filter plugs or mouthpieces. In this device, a roller conveyor having a roller surface and an associated stationary counter-roller surface are provided, with the roller surface and counter-roller surface forming a roller channel for rolling the groups with the connecting leaves and being movable relative to one another. In this known device, moving webs are assigned to the stationary counter-rolling surface before the groups enter the rolling channel, which follow the direction of movement of the rolling surface of the roller conveyor at a lower speed while gripping the groups by friction. This gives the items a negative acceleration so that they are already ahead be set in motion when they enter the roll channel. This pre-acceleration leads to a reduction in the negative acceleration acting on the objects as they enter the rolling channel and thus to greater protection of the rod-shaped objects to be rolled.

Another device for rolling rod-shaped objects is from EP 0 687 424 B1 known. Herein a device is disclosed in which revolving, speed-controlled sub-rolling surfaces are each provided with a start bar, which interact with a stationary roll surface without a start bar.

One object of the invention is to enable rod-shaped articles, in particular filter cigarettes or multi-segment filters, to be securely wrapped with, in particular, thicker tipping paper.

The invention is achieved by a device for wrapping rod-shaped articles in the tobacco processing industry, in particular filter cigarettes or filter rods or multi-segment filters, using a wrapping strip of finite length with a conveyor drum for transversely axial conveying of the rod-shaped articles, the conveyor drum having receiving depressions for receiving rod-shaped articles and the receiving troughs are arranged one behind the other in the circumferential direction of the conveyor drum, with the conveyor drum being or being driven to rotate about an axis of rotation, with a roller belt conveyor for the rod-shaped articles having a roller belt being arranged on the conveyor drum, with the roller belt conveyor being designed in such a way that in an initial position, in which no bar-shaped articles are arranged in the receiving troughs, in particular in the area of the roller conveyor, the roller belt and several receiving troughs arranged opposite the roller belt in contact with brought together and in a working position in which rod-shaped articles are arranged in the receiving troughs of the conveyor drum and are conveyed by rotation of the conveyor drum, a rolling channel is or will be formed between the receiving troughs of the conveyor drum and the roller belt of the roller conveyor, wherein in the working position the roller conveyor is in contact with the articles arranged and conveyed in the formed roller channel.

The invention is based on the idea that by providing a roller conveyor that interacts with a conveyor drum, it is also possible to use thicker material for the wrapping strips or for the lining paper strips and to completely enclose the rod-shaped articles in the roller channel by means of the roller conveyor. As a result, for example, the wrapping closure when wrapping the rod-shaped articles is completely achieved, so that after the wrapping of the rod-shaped articles, no flag of the wrapping strip or the like protrudes from the product or article in the area of the overlapping seam. By providing the roller belt conveyor with the roller belt, it is possible to specifically influence or regulate the pressing force on the wrapping strip or on the rod-shaped article to be wrapped in the roller channel, depending on 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 roller channel, the roller belt is brought into contact with the receiving troughs of the conveyor drum arranged or located in the roller channel. When production of the device or machine starts, the first rod-shaped articles, to which a wrapping strip, such as a wrapping paper strip, is attached as a flag with a free end, are attached so that, for example, two free ends or one free end of the wrapping strip protrude from the rod-shaped article , successively introduced into the roller channel, so that the roller channel between the roller conveyor and the conveyor drum is opened by the introduction of the first rod-shaped articles into the roller channel and the rod-shaped articles are set in rotation about their longitudinal axis due to a counter-pressure from the roller conveyor and at the same time the attached slip of paper or the attached wrapping strip is applied to the respective rod-shaped articles and pressed.

The conveyed roller band ensures that the rod-shaped articles are completely wrapped with the wrapping strip, with the roller band additionally applying a pressure force to the respective rod-shaped article and the end of the wrapping strip at the winding end, as a result of which the winding end of the wrapping strip is securely bonded . As a result, complete bonding is also achieved with thicker wrapping strips.

In addition, the design of the device is characterized in that in the working position the roller conveyor is or can be conveyed at a greater speed than one or the conveying speed of the conveyor drum, and/or in the working position the roller conveyor along the roller channel has the same conveying direction as the Has conveyor drum. This ensures that a differential speed is formed between the conveyed roller belt and the rotating conveyor drum, with the rod-shaped articles being accelerated in the roller channel due to the higher speed of the roller belt compared to the conveying speed of the conveyor drum and thus in the direction of the conveying direction to a preceding conveying section, in particular Conveyor segment, the conveyor drum and / or a leading receiving trough is funded on the conveyor drum. The roller belt is preferably moved along the roller channel in the same conveying direction as the rotatingly driven conveying drum. For example, the conveyor belt is conveyed here at a conveying speed or overspeed that is 1.1 times the conveying speed of the conveying drum.

The roller conveyor 20 is arranged on the conveyor drum 10 in order to wrap stick-shaped articles 30 arranged on the conveyor drum in cooperation with the conveyor drum 10 with wrapping strips 40 attached to the rod-shaped article 30 . On the conveyor drum 10, the rod-shaped articles 30 are placed in the transverse axial direction in receiving troughs 12 (cf. 2 ) promoted. The receiving troughs 12 in which the rod-shaped articles 30 are received are formed on conveyor segments 14 or conveyor sections of the conveyor drum 10 .

A suction roller 50 or covering roller is arranged on the conveyor drum 10 upstream of the roller conveyor 20 , by means of which the wrapping strips 40 are attached to the rod-shaped articles 30 . The wrapping strips 40 are attached to the rod-shaped articles 30 in such a way that the trailing free end of the wrapping strips 40 protrudes from the rod-shaped articles 30 . The front end of the wrapping strips 40 is adhered to the stick-shaped articles 30. FIG.

How out 2 As can be seen, the conveyor drum 10 has conveyor segments 14 which are arranged one behind the other in the circumferential direction and on which the receiving troughs 12 are formed on the outside for a rod-shaped article in each case. Rolling surfaces 16.1, 16.2 are formed on the outside of the conveyor segments 14 on both sides of the receiving troughs 12, so that the rod-shaped articles 30 are rolled off within a rolling channel 25 formed between the roller belt conveyor 20 and the conveyor drum 10.

In the circumferential direction, the suction roll 50 has segments 51 for the cut wrapping strips 40, which are attached to the rod-shaped articles 30 be handed over and attached. The segments 51 of the suction roller 50 each have a trough 52 into which the rod-shaped articles are moved when the wrapping strips 40 are attached to the rod-shaped articles 30 in the interaction of the synchronously rotating suction roller 50 and conveyor drum 10, whereby the leading ends of the attached, glued Wrapping strips 40 are pressed onto the rod-shaped article 30 via a surface contact from above and the respective trailing free end of the wrapping strip 40 is designed as a flag.

The conveyor segments 14 of the conveyor drum 10 have radially outwardly projecting, preferably needle-shaped, spacers 15 on the upper side for the trailing free ends of the attached wrapping strips 40, whereby contact of the trailing free ends with the surfaces of the conveyor segments 14 is avoided, since the trailing free ends rest on the spacers 15.

In 3 a further representation of the roller channel 25 formed between the roller conveyor 20 and the conveyor drum 10 is shown schematically. The roller conveyor 20 has a roller 21 on the input side and a roller 22 on the output side.

The rollers 21, 22 for the conveyor belt 23 are driven by a motor, the conveyor belt 23 being conveyed at a speed which is greater than the web speed of the adjacent conveying drum 10. As a result, when the rod-shaped article 30 with the attached wrapping strip 40 is fed in or introduced, the respective rod-shaped article 30 is accelerated in the rolling channel 25 and the rod-shaped article 30 is rolled out of the receiving trough 12 in the conveying direction, as a result of which the wrapping strip 40 is wrapped around the rod-shaped article 30 in the rolling channel 25 is wound with rotation about its longitudinal axis. When the rod-shaped articles 30 enter the rolling channel 25 , the partial vacuum applied to the receiving troughs 12 is switched off, as a result of which the rod-shaped articles 30 are released for (re)rolling in the rolling channel 25 .

Before the start of production on the drum arrangement T, which is part of a filter attachment machine or a multi-segment filter manufacturing machine, for example, there are no rod-shaped articles 30 in the receiving troughs 12 of the conveyor drum 10 or in the roller channel 25. The roller belt 23 is in a rest position on the outside of the conveyor drum 10 on the conveyor segments 14. When starting up and during continuous operation of the machine or the drum arrangement T, the rod-shaped articles 30 are introduced into the roller channel 25, as a result of which the roller channel 25 is between the conveyor drum 10 and the section of the roller belt 23 that is conveyed between the roller 21 and the roller 22 on the output side , is formed. The rolling channel 25 is thus only formed when rod-shaped articles 30 are introduced into the rolling channel 25 at the start of production. The speed of the roller conveyor 23 is determined in such a way that the rod-shaped articles 30 to be wrapped by the attached wrapping strip are again arranged at the end of the roller channel 25 in a receiving trough 12 of a leading conveyor segment 14 . When the completely wrapped rod-shaped articles 30 emerge from the rolling channel 25, negative pressure is switched on again in the receiving troughs 12 of the conveyor segments 14, so that the wrapped rod-shaped articles 30 are safely conveyed further on the conveyor drum 10.

In order to tension the roller belt 23, the roller belt 23 is guided over a tension roller 24 between the roller 22 and the roller 21 in the conveying direction. Within the scope of the invention it can be provided that the tensioning roller 24 is tensioned by means of a tensioning device, such as a spring or the like. It can be provided that the tension of the roller band 23 is controlled by means of a control device (not shown here) or is regulated by means of a control device (not shown here).

This in 4 illustrated embodiment differs from that in 3 illustrated embodiment characterized in that in the conveying direction of the roller conveyor 23 between the roller 21 and the roller 22, a roller guide 26, for example in the form of a rolling hand, is arranged. This achieves reliable guidance of the roller conveyor 23 along the roller channel 25 . In a further embodiment, it can be provided that the roller guide 26 is heated, for example, by means of a heating cartridge or a heating device.

In figure 5 is a schematic perspective view of a conveyor segment 14 for in the Figures 1 to 4 Conveyor drum 10 shown shown according to a further embodiment.

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

Furthermore, the conveyor segment 14 has a leading rolling surface 16.1 and a trailing rolling surface 16.2 in relation to the conveying direction of the conveyor drum. While the rod-shaped articles 30 are being rolled in the rolling channel 25, the rod-shaped articles arranged in the receiving troughs 12 are rolled off the receiving trough 12 over the leading rolling surface 16.1, as a result of which the attached wrapping strip 40 is wrapped around the respective rod-shaped product 30. Furthermore, the conveyor segment 14 has a second receiving trough 18 in which the completely wrapped rod-shaped articles 30 (from the trailing conveyor segment and after rolling on the trailing rolling surface 16.2) are arranged after they have been wrapped. In the receiving troughs 18 is in this case, the rod-shaped article 30 was taken up by the trailing conveyor segment of the conveyor drum.

In order to keep the rod-shaped articles in the receiving troughs 12 or 18 outside of the rolling channel 25, the receiving troughs 12 or 18 are each provided with suction air bores or the like, to which negative pressure is applied.

Furthermore, in an embodiment of the conveyor segment 10 not shown here, it is possible for the rolling surface 16.1 and/or the rolling surface 16.2 to each have outwardly projecting or protruding spacers for the free ends of the wrapping strips attached to the rod-shaped articles, whereby the free ends provided with adhesive the wrapping strips do not touch the rolling surfaces 16.1, 16.2.

In 6 a further exemplary embodiment of an arrangement of a roller conveyor 20 on a conveyor drum 10 is shown. In 7 an enlarged detailed view of the roller conveyor 25 on the conveyor drum 10 is shown.

The conveyor drum 10 has receiving troughs 120 in the circumferential direction, with the receiving troughs 120 each being formed by two support rods 121, 122 aligned parallel to the axis of rotation of the conveyor drum 10. The support rods 121, 122 are rotatably mounted. The roller belt conveyor 20 has a circulating, flexible roller belt 23 which is guided over the roller 21 and the roller 22 .

In the conveying direction of the roller conveyor 23 , the roller channel 25 for the rod-shaped articles on the conveyor drum 10 is formed between the roller 21 and the roller 22 in cooperation with the conveyor drum 10 . Wrapping strips are attached to the rod-shaped articles with a free end (not shown here), with the wrapping strips being wrapped around the rod-shaped articles within the rolling channel 25 .

Due to the fact that the support rods 121, 122 are rotatably mounted, when the rod-shaped articles arranged thereon are introduced, the rod-shaped articles are set in rotation in the roller channel 25 by means of the acting roller belt 23, so that the rod-shaped articles 30 are wrapped by the attached wrapping strip. Furthermore, between the roller 22 and the roller 21 there is a tensioning roller 27 which is acted upon by a (resetting) force in order to tension the roller band 23 .

When a machine starts production, there are initially no rod-shaped articles in the roller channel 25, so that the roller belt 23, which is kept taut, rests on the support rods 121, 122 arranged in the roller channel 25 and is in contact with them. When the rod-shaped articles 30 are introduced into the rolling channel 25 by rotation of the conveyor drum 10, the roller belt 23 is lifted by the rod-shaped articles 30 introduced, so that the rolling channel 25 is formed.

In order to drive the roller belt 23, the roller 21 is connected by means of a drive (not shown here), whereby the roller 21 is set in rotation in order to convey the roller belt 23.

8 FIG. 12 shows schematically a drum assembly T according to a further embodiment. Covering strips cut to length are attached to the rod-shaped articles on the conveyor drum 10 by means of the suction roller 50 . In this case, the suction roller 50 is preferably designed with troughs in order to achieve a large area for pressing on the rod-shaped articles with a particularly slight pressure, as a result of which the wrapping strips are securely attached to the respective rod-shaped articles.

The rod-shaped articles provided with wrapping strips are then moved on the conveyor drum 10 in the direction of the first roller conveyor 20 or the (first) roller channel 25 on the conveyor drum 10, with inside the roller channel 25 between the roller belt 23 of the Roller conveyor 20 and the conveyor drum 10, the rod-shaped articles are rotated. The rod-shaped articles roll off on the conveyor segments 14 of the conveyor drum 10 . Preferably, the conveyor segments 14 according to the in figure 5 illustrated embodiments formed. The additional receiving trough 18 positions the rolled rod-shaped articles at the end of the rolling channel 25 in the receiving troughs 18 of the leading conveyor segment, with the winding end of the wrapping strip being aligned in a predetermined position at the exit of the rolling channel 25 .

At the in 8 illustrated embodiment, the roller conveyor 23 is guided between the input-side roller 21 and the output-side roller 28 .

When the rod-shaped articles are rolled within the rolling channel 25, the roller belt 23 is conveyed at a higher speed compared to the transport speed of the rod-shaped articles in the receiving troughs 12 (cf. figure 5 ) the conveyor drum 10, in a corresponding manner according to the embodiments in the Figures 1 to 4 . Due to this, in particular low, higher differential speed or overspeed of the roller conveyor 23, the rod-shaped articles, such as assembled segment groups, are pushed forward out of the trough 12 in the conveying direction of the conveyor drum 10 (cf. figure 5 ) rolled, whereby the respective wrapping strip is wrapped around the rod-shaped article.

In particular, the rod-shaped articles are wound within the rolling channel 25 in such a way that the winding end in the receiving trough 18 of the leading conveyor segment 14 is in the trough surface of the receiving trough 18 in contact with the trough surface, so that when the rod-shaped articles are transferred from the conveyor drum 10 to a subsequent conveyor drum 100, the winding closure of the rod-shaped articles after the transfer to the conveyor drum 100 is on the outside or on top.

A roller conveyor 110 is also arranged on the (second) conveyor drum 100 in order to produce the rod-shaped articles arranged on the conveyor drum 100 with a completely closed winding closure. The second roller conveyor 110 makes it possible, even with thicker wrapping strips, to firmly bond and press on a wrapping strip that is (initially) not completely glued and not in contact with the rod-shaped article or its winding end.

The roller conveyor 110 has a roller 111 on the input side and a roller 112 on the output side. A roller belt 113 is guided over the rollers 111, 112, so that the section of the roller belt 113 guided between the rollers 111 and 112 and the conveyor drum 100 form a roller channel 115 through which the rod-shaped articles are conveyed. The roller conveyor 113 is conveyed back from the roller 112 via a further, preferably driven, roller 116 to the roller 111 on the input side. In addition, a tension roller 114 is arranged on the roller belt 113 in order to tension the roller belt 113 .

After the (partially or incompletely) wrapped rod-shaped articles have been transferred from the (first) conveyor drum 10 to the following (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 strips is on top or on the outside on the Conveyor drum 100 is arranged. The rod-shaped articles are then conveyed into the rolling channel 115 with the winding end of the wrapping strip pointing outwards.

The conveying speed of the roller belt 113 is set in such a way that when the open winding end of the wrapping strip for the rod-shaped articles comes into contact with the roller belt 113, the rod-shaped articles in the roller channel 115 are not moved and pressure is thereby exerted on the open, outside or external winding end of the wrapping strip causes whereby the open wrap end of the wrapping strip is fully connected to the stick articles. In this case, the conveying speed of the roller conveyor 113 corresponds to the conveying speed of the rod-shaped articles not moving on the conveyor drum 100 .

In an alternative embodiment, it is possible for the roller belt 113 to be moved at a lower (differential) speed than the conveying speed of the rod-shaped articles on the conveying drum 100 before entering the roller channel 115 . Due to a (negative) speed difference between the roller belt 113 compared to the conveying speed of the rod-shaped articles on the conveyor drum 100 before entering the roller channel 115, the rod-shaped articles in the roller channel are rolled out of the receiving troughs of the conveyor drum 100 in the opposite direction to the conveying direction of the conveyor drum 100, as a result of which the open winding end of the wrapping strip is closed by a further rolling process by means of the roller conveyor 110. At the end of the rolling channel 115 the rod-shaped articles rolled (backwards) in the rolling channel 115 are arranged in a trough of the conveyor drum 100 .

In 9 a further embodiment of a drum arrangement T is shown schematically. The roller belt conveyor 20 also has a tiltable or pivotable roller 29 for the roller belt 23 guided over the rollers 21, 28, 22, whereby the tilting or pivoting of the roller 29 changes the position of the roller belt 23 in relation to that on the conveyor drum 10 conveyed rod-shaped article 30 is moved to the left or right, ie along the longitudinal axis of the rod-shaped article 30, whereby the roller conveyor 23 for the rolling of the rod-shaped article 30 with the respectively attached wrapping strip 40 is or is exactly aligned. For this purpose, the roller 29 is arranged on the drum arrangement T by means of a corresponding movable holder. In order to glue or pivot the roller 29, a control unit (not shown here) with a sensor for detecting the position of the roller belt 23 in the roller belt conveyor 20 is also provided transmits the detection signals to a corresponding evaluation device. By means of the evaluation device, which in particular carries out a target/actual value comparison for the detection signals, the holder for the roller 29 and thus the roller 29 is tilted or pivoted, for example by means of a drive, if a predetermined target value is exceeded, about the roller conveyor 23 guided over the roller 29 in its initial orientation or in a predetermined orientation with respect to the rod-shaped articles 30 moved with the roller conveyor 23.

In order to keep the roller belt 23 taut during the operation of the roller belt conveyor 20, the roller belt conveyor 20 has a tension roller 127 that is mounted so that it can pivot.

Out of 9 It can also be seen that the suction roller 50 is provided on the conveyor drum 10 upstream of the roller conveyor 20 and a feed drum 60 is provided upstream of the suction roller 50 for feeding and transferring the rod-shaped articles 30 to the conveyor drum 10 .

All of the features mentioned, including those that can be taken from the drawings alone and also individual features that are disclosed in combination with other features, are considered essential to the invention alone and in combination. Embodiments according to the invention can be fulfilled by individual features or a combination of several features.
