Description

  The present invention relates to a method for joining smoking material components in the form of a cigarette-suction group fed on a roller with a regular pitch interval and coated with glue and a trough drum. About.

Furthermore, the present invention is for combining smoking material components in the form of cigarette-mouthpieces fed on a roller and at a regular pitch interval and applied on a trough drum with a glued piece of paper. Relating to the device. The invention also relates to a machine in the tobacco processing industry, in particular a machine for producing filter cigarettes, comprising an apparatus of the type described at the outset.

  In the meaning of the present invention, the constant pitch interval means a pitch interval determined by a predetermined length of the combined paper piece.

  An apparatus for coupling a cigarette-mouthpiece group with a bonded paper strip by wrapping it together is known from, for example, US Pat. In this document, the smoking material components are moved through the rolling path, with the smoking material components being rotated about their axis during their forward movement.

  The method and apparatus of the type described above is particularly useful for preparing filter cigarettes that are transported in the transverse direction in a filter loader. The efficiency of this device with respect to articles manufactured and produced per unit time has increased dramatically with the passage of time, so that it adapts to the increased working capacity of cigarette making machines connected in front of the work line. Had to be done. In this case, the rolling device of the type described at the beginning as a partial device unit in a filter mounting machine has reached a critical efficiency limit, and exceeding this efficiency limit inevitably results in a reduction in quality and waste tobacco. Increased generation, damage, deformation or even destruction of the manufactured cigarette.

  Patent Document 2 discloses an apparatus for guiding a coated paper piece and a cigarette-filter group in combination. In this apparatus, the coated paper piece is supplied to a drum with a trough. When these groups are delivered to the coated paper supply drum, the coated paper pieces are wound around these cigarette-suction groups.

Further, Patent Document 3 describes a method and apparatus for joining smoking articles. According to the technique taught in this patent document, the smoking material components are connected to each other by two rolling strokes performed one after the other. In this case, the first partial rolling stroke is performed during and when the bound paper piece is delivered to the cigarette-suction group within the trough drum housing. The final rolling stroke is performed in a manner that causes a number of rotational movements of the smoking material components that are partially combined in the other process strokes.
European Patent No. 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 ensure a high production quality of smoking articles, even in the relatively high production work efficiency of cigarette production.

  According to the present invention, there is provided a method according to the invention in the manner described at the outset, in which the binding paper strips are arranged on the cigarette-mouth group with two free ends during delivery, and the smoking material in the next step This is solved by wrapping the binding paper strip around the butting position of the cigarette-mouth group by rolling the components. In the present invention, the position of the cigarette-mouth group on the trough drum or in the trough drum must not change, and the free end of the binding paper piece is attached to the cigarette-mouth group in the middle stroke. This is based on the basic idea that a partial winding of the cigarette-mouthpiece group must be performed. In this case, the free length of the binding paper strip is shortened, so that the end of the binding paper strip is released from the following cigarette-mouth group and is not caught by this binding paper strip. The complete coupling of the cigarette-mouth group with the binding paper piece is performed by subsequently rolling the smoking material component, so that the binding paper piece completely surrounds the cigarette-mouth group butt position. . The bonded paper piece on the cigarette-mouth group is provided with a leading edge that is joined to the cigarette-mouth group after delivery, thereby providing a smoking material configuration that is two-sided and partially bonded. The pitch interval between elements is shortened. This is because the gap between the free end at the rear of the bonded paper strip and the subsequent cigarette-mouthpiece group is enlarged. Subsequently, this gap is shortened, so that the filter mounting machine can work with a high production work efficiency.

If the binding paper pieces are asymmetrically arranged on the cigarette-mouth group, the leading free ends of the binding paper pieces are bonded or partially connected to the cigarette-mouth group. In this case, the coated paper piece is supplied by a smooth supply drum.

  Secure partial coverage of the cigarette-suction group can be achieved by placing the binding paper pieces on the cigarette-suction group and then joining the binding paper pieces and the cigarette-suction group by attaching the free ends of the binding paper pieces. Can be reached by doing. This is done in the process step after arranging the bound paper pieces on the cigarette-mouthpiece group. In particular, the front free end in the feeding direction of the cigarette-mouthpiece group of the combined paper pieces is attached to the cigarette-mouthpiece group.

  In particular, the free end of the binding paper piece is attached onto the cigarette-suction group by an attachment mechanism.

  Furthermore, it is advantageous to reduce the pitch spacing of partially assembled smoking material components. After joining the partially bonded smoking material component and the partially coated material, between the free end following the bound piece of paper and the next, similarly partially coated cigarette-mouthpiece group Is larger than in the cigarette-suction group. If the pitch interval is shortened according to the invention, for example by means of a movable arm of the trough drum, the transport means provided behind the trough drum are likewise operated at a smaller pitch interval, so that the overall high production article The productivity of the machine is improved under the quality of. Accordingly, a large number of cigarettes per minute are transferred and manufactured in the machine by changing the pitch interval, i.e. reducing the pitch interval. At the same time, the smoking material component is handled without damage.

  It is advantageous to reduce the pitch spacing of the trough drum receptacle after the smoking material components are partially joined. This reduction in pitch spacing is achieved by attaching the leading free end of the binding paper piece to the cigarette-mouthpiece group, followed by the following free end and similarly partially coated cigarette- This is based on the idea of expanding the gap between the free ends of the mouthpiece group. This larger gap makes it possible to reduce the pitch spacing on the subsequent equipment, i.e. the transfer drum, so that the filter mounting machine operates at a higher throughput with respect to the manufactured cigarette. By reducing the spacing between the partially wound objects, the smoking material components that are subsequently partially joined together are delivered to the take-up drum at a reduced pitch spacing.

  According to an advantageous further embodiment of the method according to the invention, the partially bonded smoking material component is applied to the drum after being partially bonded, in particular at a pitch interval corresponding to the reduced pitch interval of the troughed drum. Delivered. Thus, for example, the filter mounting machine is operated at a slight pitch interval after the smoking material component is taken from the continuum unit.

In order to ensure that the smoking material components are delivered together in bulk, the present invention guides the bonded paper strip and the cigarette-mouthpiece together at equal pitch intervals.

  If the pitch spacing between the partially joined smoking material components is changed, this increases the pitch spacing of the trough drum receptacle after the partially joined smoking material components are delivered. There is a need. The adaptation of the reduced pitch spacing to the original pitch spacing ensures reliable operation of the method and apparatus.

  A secure adhesive bond between the smoking material components is ensured by a rolling process after delivery of the partially bonded 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.

  Furthermore, the object of the invention is solved by a device according to the invention, which device is arranged to arrange a piece of binding paper on a cigarette-mouth group with two free ends.

According to the present invention, to attach the bound paper pieces at the pitch interval of the free end preceding the cigarette-suction group, smoking is achieved by attaching the free end of the bound paper piece, particularly the front free end in the transport direction, to the cigarette-suction group. Means are provided for partially joining the material components. By arranging the binding paper pieces asymmetrically on the cigarette-mouth group, the preceding free part of the binding paper pieces is pressed together and joined together with the cigarette-mouth group. The free part that follows the bound piece of paper forms a kind of small flag (paper piece) .

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

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

If the means for partial bonding comprises at least one attachment means and a protrusion, the free end of the binding paper piece is attached on the cigarette-mouthpiece group without forming a fold.

  In particular, the adhering means has a pitch interval equal to the accommodating portion of the troughed drum when the binding paper pieces are disposed.

  Furthermore, it is advantageous that the receiving part of the troughed drum can be changed with respect to the pitch interval. This allows the partially bonded smoking material components to be delivered to the take-up drum at a reduced pitch interval.

  Advantageously, at least one rotation station is provided for winding the binding paper piece around the butting position of the cigarette-mouthpiece group. The rotating station can be constituted by a rolling block as disclosed in Patent Document 4 or a rolling path formed by a belt as disclosed in Patent Document 5 selectively.

  In accordance with the present invention, in a filter cigarette production line, a constant and reduced load on the articles during the production process under the required and reachable high processing work efficiency and thus the production work efficiency. The action is achieved. In addition, the present invention achieves speed reduction and noise reduction based thereon, thus generally increasing the efficiency of the filter mounter.

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

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

  The other transport means involved in the stroke of the device 30 is formed as a troughed drum 6 which is provided with a drum trough 8 on a trough arm which rotates in the direction of the arrow 7 and moves. A transfer device having a moving trough arm for a rod-shaped article is disclosed, for example, in US Pat.

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

  The combined paper piece 3 and the drum trough 8 have equal pitch intervals when the combined paper piece 3 is delivered to the cigarette-suction group 9.

  When the suction roller 2 and the transfer drum 6 are rotated synchronously, the combined paper piece 3 and the cigarette-suction mouth group 9 are moved in directions approaching each other and guided together. When the binding paper piece 3 and the cigarette-mouth group 9 are guided together, the binding paper piece 3 is asymmetrically attached to the cigarette-mouth group 9 with the front free end 4 and the rear free end 5. Next, each of the cigarette-suction mouth groups 9 and the bonded paper pieces 3 attached thereto are moved in the direction of the transfer drum 18 so as to be separated from the suction roller 2. In this case, the combination of the combined paper piece 3 and the cigarette-suction mouth group 9 is performed along the paper piece guide part 24. The paper piece guide 24 prevents the combined paper piece 3 from being peeled from the cigarette-suction mouth group 9.

  Next, the cigarette-mouthpiece group 9 is supplied to the star-shaped rolling member 25 along the paper piece guide portion 24 together with the combined paper piece 3. This star-shaped rolling member is provided with a protrusion 27 provided on the outside as a rotating body as a rotating body. The pitch interval of the protrusions 27 of the star-shaped rolling member 25 corresponds to the pitch interval of the drum trough 8 of the suction roller 2, that is, the pitch interval of the holding member 28 of the suction roller 2. In order to partially cover the cigarette-mouthpiece group 9 with the front free end 4 of the binding paper strip 3, the projection 27 contacts this front free end 4 of the binding paper strip 3 and thereby this front free end. 4 is attached to the cigarette-mouthpiece group. The rotational motion of the star-shaped rolling member 25 is performed in synchronization with the rotational motion of the trough drum 6. During this partial coating process, the free end 5 behind the binding paper piece 3 does not change its relative position with respect to the cigarette-mouthpiece group 9. After partial covering, i.e. partial bonding, by the binding paper strip 3, the pitch spacing between the drum receptacles 8 is shortened, so that these drum receptacles 8 are partly coupled to the smoking material components 3, 9 which are rolling drums. When delivered to 18, it has a shortened (pitch) spacing. After the partially bonded smoking material components 3, 9 are delivered to the rolling drum 18, the pitch spacing between the drum housings 8 is increased again, so that the space between these drum housings 8 in the suction roller 2 is increased. The pitch interval again corresponds to the pitch interval of the bonded paper pieces 3.

  The rolling drum 18 is a partially coated combination of the binding paper piece 3 and the smoking material component 9 in the direction of arrow 19, for example, a rolling path is formed between the rolling block and the outer periphery of the rolling drum 18. To the rolling station (not shown here). At this rolling station. The rolling surface of the rolling block is significantly longer than the peripheral surface of the cigarette-suction group 9, so that the cigarette-suction group is rotated a number of times and coupled with the binding paper piece 3. Alternatively, the rolling can be performed by a belt as disclosed in Patent Document 5, for example, instead of the rolling block.

  FIG. 2 shows in detail the attachment of the front free end 4 of the binding paper piece 3 to the cigarette-suction group 9 by the star-shaped rolling member 25. A star-shaped rolling member 25 is used for the protrusion 27. When the star-shaped rolling member 25 and the trough drum 6 are rotated synchronously, the protrusion 27 contacts the front free end 4 of the binding paper piece 3 with respect to the transport direction of the trough drum 6. The cigarette-sucking group 9 is approached until it is pressed against the cigarette-sucking group 9. The rear free end 5 of the binding paper piece 3 on which the (rear) mandrel 14 of the drum housing 8 rests and is supported by it does not change its length during this partial coupling.

 Although this method and apparatus dramatically improves the efficiency of the filter mounting machine for producing cigarettes in the tobacco processing industry, it can also be used to process other smoking materials such as cigarettes.
