Description

  The present invention relates to a method for assembling smoking elements and to machines in the tobacco processing industry, in particular filter mounting machines.

  In a filter mounting machine, one filter piece or mouthpiece is inserted between tobacco rods that are cut and separated in the longitudinal direction. Subsequently, the glued connecting paper pieces are glued to the combined cigarette-suction-cigarette-group. At this time, the glued connecting paper pieces are supplied via a suction roll to a coating apparatus having a group of cigarettes, suction openings, and cigarettes at predetermined pitch intervals. The predetermined pitch interval is a preselected interval of the group of cigarettes-mouthpieces-cigarettes-which is greater than the length of the connecting piece of paper.

  A method and an apparatus of the kind described above serve for the mass production of filtered cigarettes conveyed transversely on a so-called filter applicator. The output of this method or device, with respect to the parts produced and released per unit time, must be adapted to the increased performance of the cigarette extruder, which has risen rapidly over time or is connected upstream. did not become.

  Patent Document 1 (corresponding to U.S. Pat. No. 5,054,346) describes a paper coating apparatus for a filter mounting machine. In this case, the glued coated paper is supplied as an endless coated paper strip and cut into individual paper pieces or connecting paper pieces by a cutting device. After cutting, the splice pieces are broken apart and accelerated to the conveyor speed of the cigarette-filter-cigarette-group transported in small portions.

  U.S. Pat. No. 5,715,838 describes a filter mounting machine for a double continuum-cigarette making machine. Two different transport paths for tobacco articles are provided for bonding and winding the coated paper strip.

It is furthermore known from US Pat. No. 5,059,067 that a cigarette-filter-cigarette-group is provided with a covering piece. On a first drum, a first group of a group of cigarette-filter-cigarette-groups is provided with a coating strip of coating equipment and a second group is transported out of the transport path of the first group. , On the second drum, the coated strip of the second coating device is provided. Subsequently, the winding of the two separate groups by a piece of paper takes place on a separate roll device. Only after each winding does the group rejoin the group's alternating row.

  Starting from this state of the art, the problem underlying the present invention is to ensure a high product quality of the smoking articles of the filter-fitting machine, even with a high production capacity. In this case, the structural costs should be reduced as much as possible.

  The object is to provide a first coating device with articles of a first and a second group having a cigarette-mouth-smoking-cigarette-group, each of which is provided with a connecting piece of paper, The first and second groups of articles are supplied to a second coating apparatus, and the second group of articles are each provided with a connecting piece of paper, and the first and second groups of articles are connected by a connecting piece of paper in a roll device. The problem is solved by a method for combining rolled, smoking elements.

  Providing two coating devices on a single track filter mounting machine increases production capacity. That is, the feeding of the coated paper strip takes place in two tracks, whereby the first group of articles is equipped with the coated paper strip by the first coating device and the second group of articles is coated by the second coating device. Because it is provided. Thereby, the transport drum or the transport means can be operated at high speed. Thus, the quality of the manufactured cigarettes is improved because the coated paper pieces adhere to the respective article groups reliably.

  In this case, it is advantageous if the connecting piece is transferred onto the article while the article group is being transported by the transport means. By transporting the articles by one transport means and simultaneously attaching the connecting pieces to the article group, the structural costs are significantly reduced. In this case, it is not necessary for the article groups to have different transport paths in order to equip the coated paper strip.

  A further improvement is achieved in that the connecting pieces are partially adhered after they have been transferred onto the article. The attachment of the free end of a connecting piece of paper to a cigarette-suction-cigarette-group is described in EP-A-0 202 2354.8. In this case, a star-folding machine or a so-called star-winding machine is provided for attaching the free end of the connecting piece of paper to the tobacco article.

  In another embodiment, the first and second groups of articles are alternately placed on the transport means before transferring the connecting pieces to the first group.

  Furthermore, it is desirable for the connecting piece of paper to be transferred at a constant speed to the first and / or second group of articles.

  The task is further provided with a coating device arranged in the conveying direction of the article group and a common roll device for the first and the second group of the cigarette-suction-cigarette-group, respectively. Solved by machines in the tobacco processing industry, in particular filter mounting machines.

  In the idea of the present invention, the coated paper strip is supplied to the single-track type filter mounting machine in a two-track shape, so that the machine can be operated at a high conveying speed. Both coating devices improve the adhesion of the piece of paper to the group of articles. This is because one coating device no longer needs to be equipped with a coated piece of paper for every group of articles.

  The arrangement is simplified by the arrangement of the coating device on one transport means for the first and the second group of articles.

  Further, it is advantageous that the pitches of the accommodating portions of the transport means are equal. Thereby, for example, a transport drum having a predetermined pitch is used.

  In a preferred embodiment, at least one attachment mechanism is provided for at least one free end of the connecting piece of paper to the first and / or second group of articles. As a result, the connecting paper pieces adhere well to the article group during later winding of the article group. By partially adhering the connecting pieces, the starting process during winding is greatly improved.

  It is furthermore advantageous if one attachment mechanism is provided for each group of articles.

  In a preferred embodiment, the pitch of the supply drum of each coating device for the connecting pieces is twice as large as the pitch of the transport means. This is because each coating device equips half of all the conveyed article groups with connecting strips.

  It is furthermore advantageous if the length of the connecting strip of each coating device is adjustable. This makes it easier to adapt the connecting strip to be cut, for example, after changing the transport drum to a different pitch interval. When transporting cigarettes having different diameters, the transport drum needs to be replaced.

  The conveying means is in particular formed as a recessed drum or a belt conveyor.

  The machine according to the invention is preferably formed in a single track. That is, the article groups that are arranged and conveyed side by side in the horizontal axis direction are conveyed in one conveyance plane, and are formed so as to be provided with the connection paper pieces.

  Further, the present invention will be exemplarily described based on embodiments with reference to the accompanying drawings without limiting the spirit of the present invention. With respect to the disclosure, and for all details of the invention not described in detail in the specification, reference is made to the drawings.

  In the following figures, the same elements or similar elements or corresponding parts are denoted by the same reference numerals, so that the corresponding new description will be omitted, and the first embodiment will be described in the following figures. Only different points of the illustrated embodiment will be described.

  FIG. 1 schematically shows a drum arrangement according to the invention. The drum device according to the invention is used in so-called filter mounting machines known to the expert in the state of the art. The filter placement machine receives a double use length tobacco rod from the continuous cigarette former. The tobacco rod is cut along the transport path to the combination drum 21 and is expanded. At the same time, the filter rod is taken out of the filter rod magazine and cut into filter pieces, so that the filter pieces having a double length are separated in the longitudinal direction, that is, two expanded pieces, through the drum device. Inserted between tobacco sticks. Thereby, on the combination drum 21, the cigarette-suction-smoke-cigarette-groups 50 and 60 which are arranged and combined in the front-back direction in the horizontal axis direction are formed.

  The combined item groups 50, 60 are transferred to the transfer drum 22 and transferred to the first coating device 10. 1 for the first group 50. Coating devices are described in detail, for example, in DE 3918137. This coating device is fully included in the content of the present application.

  In this case, the glued and transported coated paper strip 11.1 is cut on a cutting drum 12.1 by a cutter of a cutter drum 13.1 into coated paper strips 40.1 of the same length. The cut coated paper pieces 40.1 are transferred to the first group 50 of articles on the transport drum 22 and adhered thereto.

  Subsequently, both article groups 50, 60 are further transported in the transport direction to the star-folding machine 23.1. In this star-shaped folder, the end of the coated paper piece 40.1 on the front side in the transport direction is applied to the article group 50. Next, the articles 50, 60 are further transported and fed to the coating device 10.2 for the second group of articles 60.

  The second coating device 10.2 comprises a cutter roll 13.2 which cuts the coated web 11.2 in cooperation with a suction roll 12.2. The cut pieces of connecting paper 40.2 are transported to the tobacco goods or cigarettes-mouthpieces-cigarettes-group 60 and adhered. Thereafter, the front end of the connecting strip 40.2 is attached to the article 60 on the transport drum 22 by the star folder 23.2.

  Subsequently, the articles in the first and second groups 50 and 60 are transferred from the transfer drum 22 to the transfer drum 26, and transferred to the roll device 27 having a roll pad. Thereby, the connecting pieces of paper 40.1, 40.2 are completely wrapped around the cigarette-mouthpiece-cigarette-groups 50,60. The finished articles 50, 60 are subsequently transferred to a transport drum and are ready for another processing process of the filter mounting machine.

  In the present invention, the pitch interval between the dents of the transport drum 22 is constant, that is, equal. Furthermore, the coating devices 10.1, 10.2 are modified as follows. That is, the coated paper supply drum or the suction rolls 12.1, 12.2 are deformed so as to have a pitch twice as large as that of the transport drum 22. Overall, in the case of such a single-track filter mounting machine with a two-track coated paper supply, the production output of the filter mounting machine is increased. In this case, the structural cost is small. This is because it is only necessary to arrange two coating apparatuses in one transport means.

  FIG. 2 shows an alternative embodiment of a two-track coated paper supply to the first and second groups of articles 50,60. In this case, the article groups 50 and 60 are transported linearly on the conveyor belt 32 instead of the transport drum 22 (FIG. 1). In this case, the interval between the article groups 50 and 60, that is, the pitch interval is formed to be constant on the belt conveyor 32.

1 is a schematic front view of a part of a drum device according to the present invention. FIG. 4 is a schematic front view of an alternative drum device according to the present invention.
