Description

The present invention relates to a method for bonding smoking material components in the manner of cigarette-mouth groups supplied on a roller and glued together with a glued piece of paper supplied on rollers at regular pitch intervals. About. Furthermore, the present invention is for bonding smoking material components in the manner of cigarette-mouth groups supplied on a roller and glued together with a glue-bonded strip of paper supplied at regular pitch intervals. Device. The invention also relates to a machine in the tobacco processing industry equipped with a device of the type described at the outset, in particular for producing filter cigarettes.

Constant pitch interval means, in the meaning of the present invention, a pitch interval determined by a predetermined length of a binding paper piece.

A device for binding cigarettes to a piece of cigarette by winding the group of mouthpieces together with the glued piece of glue is known, for example, from US Pat. In this document, the smoking material components are moved through a rolling path, wherein the smoking material components are rotated about their own axis during their forward movement.

The method and apparatus of the type described above is particularly useful for preparing filter cigarettes which are transported in a transverse direction in a filter mounting machine. The efficiency of this device with respect to goods manufactured and produced per unit time has increased dramatically over the years, and thus has been adapted to the increased working capacity of cigarette making machines connected in front of the work line Had to be done. In this case, a rolling device of the type described at the beginning as a sub-unit in a filter-equipped machine has reached a critical efficiency limit, which is inevitably reduced in quality and waste tobacco. It leads to increased generation, damage, deformation or even destruction of the manufactured cigarettes.

Patent Document 2 discloses an apparatus for combining and guiding a coated paper strip and a group of cigarette-filters. In this apparatus, the coated paper strip is supplied to a drum with a trough. When these groups are delivered to the coated paper supply drum, the coated paper strips are wrapped around these cigarette-mouth groups.

In addition, US Pat. No. 5,077,077 describes a method and apparatus for joining smoking articles. According to the teachings of this patent, the smoking material components are connected to each other by two successive rolling steps. In this case, the first partial rolling stroke is carried out during and during the transfer of the binding sheet to the group of cigarette-mouths in the accommodation of the drum with trough. The final rolling stroke is carried out in such a way that the smoking material components, which are partially combined in the other method strokes, are rotated a number of times.
European Patent 0 687 424 German Patent Publication No. 25 17 209 European Patent No. 0 821 887 German Patent No. 16 32 193 German Patent Publication No. 198 57 576 German Patent No. 31 37 223

The problem underlying the present invention is to guarantee a high production quality of smoking articles, even with a relatively high production efficiency of cigarette production.

The object of the present invention is to provide, according to the invention, in a method of the type described at the outset, in which the binding paper pieces are arranged with two free ends on a group of cigarette-tips during delivery, and in the next step smoking material The problem is solved by wrapping the binding piece around the cigarette-mouth group butt location by rolling the components. According to the invention, the position of the group of cigarette-mouths must not change on or in the troughed drum, with the free end of the binding piece being attached to the group of cigarette-mouths in the middle stroke. This is based on the basic idea that a partial winding of the cigarette-mouth group must take place. In this case, the free length of the binding piece is shortened, so that the ends of the binding piece are released from the following group of cigarette-tips and are not rolled up by the binding piece. The complete connection of the cigarette-tip group to the binding piece is effected by the subsequent rolling of the smoking material component, so that the binding piece completely surrounds the abutting position of the cigarette-tip group. . The two successive and partially connected smoking material components are provided by the fact that the binding piece on the cigarette-tip group has a leading end which is joined with the cigarette-tip group after delivery. The pitch spacing between elements is reduced. This is because the gap between the rear free end of the binding piece and the succeeding cigarette-mouth group is enlarged. This gap is subsequently reduced, so that the filter mounting machine can work with a high production efficiency.

If the binding strip is arranged asymmetrically on the cigarette-mouth group, the leading free end of the binding strip is glued or partially bonded to the cigarette-tip group. In this case, the supply of the coated paper strip is performed by a smooth supply drum.

Reliable partial coverage of the cigarette-tip group is achieved by arranging the binding paper pieces on the cigarette-tip group and then partially bonding the binding paper piece and the cigarette-tip group by attaching the free ends of the binding paper pieces. To be reached. This takes place in the process step after the binding pieces are arranged on the cigarette-mouth groups. In particular, the free end forward in the feed direction of the cigarette-mouth group of the binding paper pieces is attached to the cigarette-mouth group.

In particular, the free end of the piece of binding paper is deposited on the cigarette-mouth group by a deposition mechanism.

It is further advantageous to reduce the pitch spacing of the partially assembled smoking material components. After joining the partially bonded smoking material component and the partial covering material, between the trailing free end of the piece of binding paper and the next, similarly partially covered cigarette-mouth group Is larger than in the group of cigarettes-mouthpieces-a piece of paper is deposited at a location by known techniques. If the pitch spacing is reduced according to the invention, for example by means of the movable arm of a troughed drum, the transfer means provided behind the troughed drum are likewise operated at a smaller pitch spacing, and thus produce an overall higher product. The machine productivity is improved under the quality. Thus, by changing the pitch spacing, i.e., reducing the pitch spacing, many cigarettes per minute are transported and manufactured in the machine. At the same time, the smoking material components are handled without damage.

It is advantageous to reduce the pitch spacing of the troughed drum housing after the smoking material components have been partially combined. This reduction in pitch spacing is achieved by attaching the leading free end of the binding paper piece to the cigarette-suction tip so that the trailing free end is followed by a similarly partially covered cigarette. It is based on the idea of increasing the gap between the free ends of the mouthpieces. This larger gap makes it possible to reduce the pitch spacing on the subsequent device, ie the transfer drum, so that the filter setting machine operates at a higher throughput on the manufactured cigarettes. By reducing the distance between the partially wound objects, a subsequent transfer of the smoking material components that are partially connected to one another to the take-up drum at a reduced pitch distance takes place.

According to an advantageous further embodiment of the method according to the invention, the partially joined smoking material components are arranged on the drum after the partially joined drum, in particular with a pitch interval corresponding to the reduced pitch interval of the troughed drum. Delivered. Thus, for example, the filter applicator is operated at a small pitch interval after the smoking material component is withdrawn from the continuum unit.

According to the invention, the binding paper pieces and the cigarette-mouth groups are guided together at equal pitch intervals in order to ensure that the smoking material components are transported together.

If the pitch spacing between the partially joined smoking material components is changed, this will increase the pitch spacing of the troughed drum receptacle after delivery of the partially joined smoking material components has taken place. There is a need. The adaptation of the reduced pitch spacing to the original pitch spacing ensures a reliable operation of the method and the device.

確 実 A secure adhesive connection between the smoking material components is ensured by a rolling treatment after the transfer of the partially joined smoking material components to the drum.

In particular, it is advantageous to carry out the final rolling process in a manner in which the smoking material component is rotated many times.

The object of the invention is further solved by the device according to the invention, wherein the device is arranged to arrange the binding paper strip with two free ends on a group of cigarette-mouths.

According to the invention, the smoking is effected by attaching the free end of the binding paper strip, in particular the free end forward in the transport direction, to the cigarette-tip group in order to attach the binding paper strip at the pitch interval of the free end preceding the cigarette-mouth group. Means are provided for partially joining the material components. By asymmetrically arranging the binding pieces on the cigarette-mouth groups, the leading free part of the binding paper pieces is pressed together with the cigarette-tip groups and joined. The trailing free portion of the binding sheet forms a kind of small flag.

According to a further advantageous configuration, means are provided for partially connecting the smoking material component between the roller and the take-up drum with respect to the direction of transport of the troughed drum.

In particular, the means for the partial connection are formed as a rotating body and / or an attachment mechanism.

If the means for partial binding comprises at least one attachment means, in particular a projection, the free end of the binding piece is attached onto the cigarette-mouth group without forming a fold.

Particularly, the attaching means is provided with a pitch interval equal to the accommodating portion of the trough-equipped drum when the binding paper pieces are arranged.

Furthermore, it is advantageous that the accommodation of the troughed drum can be varied with respect to the pitch spacing. This allows the partially joined smoking material components to be delivered to the take-up drum at a reduced pitch interval.

Advantageously, at least one rotating station is provided for winding the binding piece around the cigarette-mouth group abutting position. This rotating station can be constituted by a rolling block as disclosed in US Pat. No. 6,037,045 or, alternatively, by a rolling path formed by a belt as disclosed in US Pat.

Furthermore, the object according to the invention is solved by a machine in the tobacco processing industry, in particular a filter mounting machine, provided with the above-mentioned device.

According to the present invention, in a filter cigarette manufacturing line, a constant and reduced load on articles during the manufacturing process under the required and achievable high processing operation efficiency and consequently the production operation efficiency Action is achieved. In addition, the present invention achieves a reduction in speed and a corresponding reduction in noise, thus generally increasing the efficiency of the filter mounting machine.

Hereinafter, the present invention will be described in detail with reference to an embodiment illustrated in the accompanying drawings, but the present invention is not limited to this embodiment.

FIG. 1 schematically shows, in cross section, a device 30 according to the invention with a number of drums, as for example formed in a filter mounting machine. The transport means of the device 30 involved in the stroke according to the invention comprises a suction roller 2 which rotates in the direction of arrow 1, on which a glue-bonded paper strip 3 is glued on the outside. The paper is supplied at a constant pitch interval that is given in advance by the length of the binding paper 3. These joined paper pieces 3 are arranged on the holding members 28 of the suction roller 2 and are held in these holding members 28 by suction air openings.

Another transport means involved in the travel of the device 30 is formed as a troughed drum 6, which is provided with a drum trough 8 on a moving trough arm which pivots in the direction of arrow 7. A transfer device with a moving trough arm for a bar-shaped article is disclosed, for example, in US Pat.

Drum trough 8 takes one cigarette-mouth group 9 each time. These cigarette-mouth groups 9 are held on the transfer drum 6 by the negative pressure applied to the suction holes 11.

The binding paper strip 3 and the drum trough 8 have the same pitch interval when the binding paper strip 3 is delivered to the cigarette-mouth group 9.

(4) When the suction roller 2 and the transfer drum 6 are rotating synchronously, the binding paper piece 3 and the cigarette-suction port group 9 are moved in a direction approaching each other and guided together. When the binding strip 3 and the cigarette tip group 9 are guided together, the binding strip 3 is asymmetrically attached to the cigarette tip section 9 with the front free end 4 and the rear free end 5. Then, the cigarette-mouth group 9 and the attached paper strip 3 are moved in the direction of the transfer drum 18 away from the suction roller 2. In this case, the combination of the combined sheet 3 and the cigarette-mouth group 9 is performed along the sheet guide 24. The paper strip guide 24 prevents the bonded paper strip 3 from separating from the cigarette-mouth group 9.

Next, the cigarette-suction group 9 is supplied to the star-shaped rolling member 25 along the sheet guide 24 together with the combined sheet 3. The star-shaped rolling member has a projection 27 provided as a rotating body in a star shape on the outside. The pitch interval between the projections 27 of the star-shaped rolling member 25 corresponds to the pitch interval between the drum troughs 8 of the suction roller 2, that is, the pitch interval between the holding members 28 of the suction roller 2. In order to partially cover the cigarette-tip group 9 with the front free end 4 of the binding piece 3, the projection 27 contacts this front free end 4 of the binding piece 3, whereby the front free end 4 is attached to the cigarette-mouth group. The rotation of the star-shaped rolling member 25 is performed in synchronization with the rotation of the drum 6 with the trough. During this partial covering process, the rear free end 5 of the binding strip 3 does not change its position relative to the cigarette-mouth group 9. After the partial covering with the binding strip 3, i.e. the partial binding, the pitch spacing between the drum receptacles 8 is reduced, so that these drum receptacles 8 have the partially joined smoking material components 3, 9 on the rolling drum. When delivered to 18, it has a reduced (pitch) spacing. After the partially joined smoking material components 3, 9 have been transferred to the rolling drum 18, the pitch distance between the drum receptacles 8 is again increased, so that between the drum receptacles 8 on the suction roller 2. The pitch interval again corresponds to the pitch interval of the binding paper 3.

The rolling drum 18 is a partially covered combination of the binding piece 3 and the smoking material component 9 in the direction of the arrow 19, for example a rolling path is formed between the rolling block and the outer circumference of the rolling drum 18. (Not shown here) at the rolling station. At this rolling station. The rolling surface of the rolling block is significantly longer than the peripheral surface of the group of cigarette-mouths 9, so that the group of cigarette-mouths is rotated a number of times and is joined to the binding paper 3. Alternatively, the rolling can be performed by a belt instead of this rolling block, for example, as disclosed in US Pat.

FIG. 2 shows in detail the attachment of the front free end 4 of the binding piece 3 to the cigarette-mouth group 9 by the star-shaped rolling elements 25. A star-shaped rolling element 25 is used for the projection 27. When the star-shaped rolling member 25 and the trough-equipped drum 6 rotate in synchronization with each other, the protrusion 27 makes contact with the front free end 4 of the binding paper strip 3 in the transport direction of the trough-equipped drum 6. Then, it approaches this cigarette-mouth group 9 until it is pressed against the cigarette-mouth group 9. The rear free end 5 of the connecting strip 3 on which the (rear) mandrel 14 of the drum housing 8 rests and is supported thereby does not change its length during this partial connection.

 This method and apparatus greatly improves the efficiency of the filter mounting machine for the production of cigarettes in the tobacco processing industry, but can also be used for the processing of other smoking materials, for example cigarettes.
