[Technical field to which the invention belongs]

The present invention relates to a method of binding tobacco article components in the form of thick binding flakes fed to a suction roller at predetermined compartmental intervals and at least one cigarette mouthpiece fed to a bucket drum.

【0002】

The present invention further relates to a device for binding tobacco article components in the form of thick binding flakes fed to a suction roller and at least one cigarette mouthpiece fed to a bucket drum at predetermined compartmental intervals. Furthermore, the present invention relates to industrial machines for processing tobacco, especially filter installation machines.

【0003】

The predetermined division interval should be understood as the division interval determined by the predetermined length of the combined paper in the sense suitable for the present invention.

【0004】

[Conventional technology]

A device for binding cigarette mouthpieces by wrapping covered binding flakes is known, for example, by European Patent Application Publication No. 687424, wherein the tobacco article component is moved through a roll passage. It is rotated around its own axis during its forward movement.

【0005】

The methods and devices of the above type are particularly used to produce filtered cigarettes transported in the horizontal axis direction on a so-called filter installation machine. The efficiencies for articles manufactured and joined per hour were repeatedly and repeatedly dramatically increased over time, or the increased efficiencies had to be applied to pre-switched cigarette strand machines. At that time, if the roll device achieves the critical efficiency limit as a subset of the filter installation machine, the excess will result in quality deterioration or tobacco defect, obstruction, deformation or complete destruction of the manufactured cigarette. Can be derived.

【0006】

Publication No. 2517299 of the German Patent Application discloses a device that assembles a cigarette filter-cigarette group and a thin sheet of coated paper from which the coated paper is supplied to a bucket drum. During the transfer of the cigarettes to the coated paper feed drum, the coated paper is placed around the cigarettes.

【0007】

In addition, European Patent No. 821887 describes methods and devices for binding this type of tobacco article. According to technical teaching, the tobacco article components are connected to each other by two consecutive rolling processes. In this case, the first partial rolling is performed in the recess of the bucket drum during or during the transfer of the combined flakes to the cigarette mouthpiece group. The final rolling is carried out in a further method step in the form of rolling several times as many as the partially bonded components.

【0008】

[Problems to be Solved by the Invention]

An object of the present invention is to guarantee high production quality of tobacco articles even with higher production efficiency.

【0009】

[Means for solving problems]

The problem is that, according to the present invention, in the case of the above-mentioned method, the cigarette mouthpiece group is partially surrounded by the binding flakes in the transition to the cigarette mouthpiece group, and due to the overrolling of the components in the next step. The solution is to wrap it around the junction of the cigarette mouthpieces.

【0010】

The present invention is based on the idea that the mouthpiece group is partially covered by a predetermined encircling angle when the bonded flakes are transferred to the cigarette mouthpiece group. In this case, according to the present invention, the cigarette mouthpieces do not change their position on or within the bucket drum, i.e. the cigarette mouthpieces do not roll during partial siege. The free length of the bonded flakes is already shortened during this process by the partial coating treated during the transition of the bonded flakes to the cigarette mouthpiece group during the assembly of the components, so that the paper edge is next. Is released from the cigarette mouthpiece group or is not recovered by this cigarette mouthpiece group. This results in the free length of the bonded flakes remaining unchanged and protruding from the cigarette as a type of cigarette flag. In order to produce a perfect bond between the cigarette mouthpiece and the binding flakes, the overrolling of the components continues to wrap the binding flakes around the junction of the cigarette mouthpieces.

【0011】

The cigarette mouthpieces are partially housed in the recesses of the suction rollers in order to provide the cigarette mouthpieces with thick coupling flakes in the form of partial winding. In this case, the recess of the suction roller is formed shape-wise and / or shape-complementary with respect to the cigarette mouthpiece group, so that the coated paper flakes are partially placed around the mouthpiece group and the mouthpiece group. It is pasted on.

【0012】

A secure first contact between the binding flakes and the cigarette mouthpiece is achieved when the binding flakes are placed asymmetrically with respect to the indentation of the suction roller. This is advantageous for this method, especially if the anterior end of the recess is shorter than the posterior end in the direction of movement of the suction roller of the combined flakes.

【0013】

The mouthpiece group is further reliably partially covered if the binding flakes are held asymmetrically and / or partially during migration.

【0014】

Reliable partial coverage of the cigarette mouthpiece group is achieved by at least partially attaching the portion of the bonded flakes that is not retained from the suction roller to the cigarette mouthpiece group.

【0015】

Furthermore, preferably the bound flakes are retained by the action of negative pressure on at least two suction holes in the suction roller.

【0016】

Cigarette mouthpieces can be enclosed by binding flakes without folding if the negative pressure in the suction holes is blocked in a predetermined order. By blocking the negative pressure, the free portion of the coupling flakes in the suction roller or suction hole can be laid flat around the cigarette mouthpieces. For example, if the suction air is blocked in a suction hole located in front of the roller transition bucket in relation to the direction of movement of the suction roller, the front end of the coupling flakes is due to the inflow of the cigarette mouthpiece into the depression. It comes into contact with the mouthpiece group and is attached to the mouthpiece group.

【0017】

According to a particularly preferred embodiment of the present invention, the transfer of the partially bound components is carried out especially after the transfer of the bound flakes to the cigarette mouthpiece group. According to the present invention, the position of the partially bonded component is moved or changed for the first time after joining and partially covering the partially bonded component. The cigarette mouthpiece group is not further wound due to the position shift of the partially bonded components. This means that the length of the free end of the partially bonded components does not change. On the other hand, the relative arrangement of the coating flag with respect to the cigarette mouthpiece group is changed. This is particularly suitable for the position of the small flag edge relative to the central axis of the cigarette mouthpiece group. In particular, the position shift of the partially bonded components can achieve a reduction in the distance between the center point of the mouthpiece group and the free end of the bonded flakes.

【0018】

In a particularly preferred embodiment of the present invention, it is contemplated that the transfer of the partially bound components into the depression of the bucket drum will be carried out. The position shift changes the relative position of the free portion of the cover paper to the cigarette mouthpieces, in which case the length of the free cover paper flag remains substantially constant. On the other hand, the distance between the protruding ends of the flakes with respect to the central axis (symmetrical axis) of the cigarette mouthpiece group is changed. In the bucket recess, the position of the wrapping side of the cover paper flakes is transferred.

【0019】

Furthermore, it is preferable when the transition is carried out by the acceleration process of the partially bonded components. The acceleration applied to the partially bonded component changes the position of the partially bonded component in the recess of the bucket drum. Since the partially bonded component has already been moved with the bucket drum, additional relative acceleration must be applied to the component, so that the depression to which this component has been moved is taken by another position.

【0020】

In addition, it is advantageous when the division interval of the partially bonded components is reduced. After joining and partially coating the partially bonded components, the spacing between the free end of the bonded flakes and the next similarly partially coated cigarette mouthpiece is a cigarette in which the flakes are pasted in one place based on technical standards. Larger for the mouthpiece group. In the case of shortening of the division interval according to the present invention, for example, due to the lack of mobility of the bucket drum, the transport means arranged at the rear of the bucket drum can be operated with similarly small divisions, so that the overall productivity of the machine. Can be increased during high production quality. Therefore, by changing the classification, a large number of cigarettes per minute are transported or manufactured by one machine. At the same time, the tobacco article component has already been processed.

【0021】

In particular, it is preferable when the separation interval of the depressions of the bucket drum is reduced during and / or after the transition. The reduction of the division interval is based on the idea that the free end of the cover paper flag is not shortened by the position movement. The spacing between two consecutive, partially bonded components can be changed by the transfer of components and the change of relative position. In this case, it should be noted that the flaky end is not wound up by the next cigarette mouth group. The shortening of the partially wound and transferred symmetries can subsequently result in a transfer to a delivery drum with a slight division of the tobacco article components partially bonded to each other.

【0022】

According to a preferred embodiment of this method, the partially coupled components are delivered to the drum after the repositioning, especially to a drum having a section that matches the reduced section of the bucket drum. This allows, for example, a filter installation machine to be operated after delivery of components from a strand unit with a small number of compartments.

【0023】

In order to ensure the aggregation of tobacco article components, the present invention contemplates the aggregation of bound flakes and a group of cigarette mouthpieces with a small spacing.

【0024】

When the division interval between the partially bonded components is changed, it is necessary to increase the division interval of the recess of the bucket drum after the delivery of the partially bonded components. Applying a reduced division interval to the original division ensures reliable operation of this method or device.

【0025】

A secure sticking bond is further suggested by performing a final winding after delivery of the partially bonded components to the drum.

【0026】

In particular, it is preferable when the final winding is carried out in the form of winding several times as many as the components.

【0027】

Further, the subject of the present invention is solved by the above-mentioned type of apparatus, which is reproduced by designating at least one means of partially binding the tobacco components upon delivery of the bonded flakes to the cigarette mouthpiece group.

【0028】

According to the present invention, the suction roller has a particularly semi-circular indentation in order to provide binding flakes when assembling the partially coated cigarette mouthpieces.

【0029】

If the indentation is formed asymmetrically with respect to the position of the coupling flakes, the front end in the direction of movement of the flakes may be pressed against the cigarette mouthpieces after switching the passage of the suction air. The trailing end of the combined flakes forms a free end as a kind of flag.

【0030】

In particular, the suction roller has at least two suction holes that hold the binding flakes. The suction holes are subjected to negative pressure to hold the bonded flakes. A favorable result is achieved by the placement of at least one suction hole in front of and behind the recess in relation to the suction roller transport direction.

【0031】

The combined flakes are partially wrapped and abutted during delivery of the combined flakes to the cigarette mouthpiece group without folding, especially if the suction holes can be blocked in a predetermined order.

【0032】

According to embodiments of the present invention, it is contemplated that the repositioning member is provided to transfer the partially bonded components. In this case, the transfer or movement of the partially bound components results in a relative repositioning of the cigarette mouthpiece and the bound flakes without further entrainment or wrapping of the mouthpiece.

【0033】

This is especially advantageous if the bucket drum recesses can be changed with respect to the partition spacing. Thereby, the partially bonded components can be delivered to a delivery drum with a small number of compartments.

【0034】

Relative changes in the position of the partially coupled components are easily performed when the bucket drum recess is widened. Based on the widening of the indentation, the cigarette mouthpieces are unwound in the indentation, at which time the cigarette mouthpiece is not further entrained by the binding flakes.

【0035】

In particular the depression has one retaining shoulder and / or a thick surface. This allows the cigarette mouthpieces to be precisely moved and placed with respect to the indentation.

【0036】

In order to change the division interval, at least one means for changing the division interval of the depression is provided.

【0037】

The displacement of the partially coupled components into the recess of the bucket drum is according to the present invention when the repositioning member between the suction roller and the delivery drum is arranged in relation to the transport direction of the bucket drum. Achieved.

【0038】

To allow for repositioning in the depression, the repositioning member has at least one means of transportation for the partially coupled components. This means of transportation exerts acceleration on the partially coupled components, resulting in repositioning of the components in the indentation. The movement of the mouthpiece group under the repositioning occurs around the axis without the cover paper being wrapped around the mouthpiece group.

【0039】

According to a preferred embodiment of the present invention, the repositioning member is formed as a rotating body.

【0040】

Further, the partially coupled components can be moved in the bucket drum recess, especially when the moving means having a large partition spacing is arranged as the maximum partition spacing in the bucket drum recess. Due to the larger division spacing of the means of transportation, the partially coupled components in the indentation undergo relative acceleration and take other positions in the indentation of the bucket drum.

【0041】

In addition, there is an advantage when at least one roll portion around which the bonding flakes are wound is provided around the joint portion of the cigarette mouthpiece group. The roll portion is a selective one formed by a roll stand, for example, as shown in German Patent No. 1632193, or by a belt, as shown in German Patent Application Publication No. 19857576. It can be realized by the roll passage.

【0042】

Further, the problems of the present invention are solved by machines in the tobacco processing industry, particularly filter installation machines, equipped with the equipment of the present invention, as described in advance.

【0043】

According to the present invention, a uniform or, in some circumstances, a totally reduced article load during the manufacturing process is achieved during the production output of the filtered cigarette line with the higher transport volume output achieved in an effort to obtain it. Will be done. Further, according to the present invention, the reduction resulting from the speed reduction and the noise speed reduction can be achieved, so that the working efficiency of the filter installation machine can be increased as a whole.

BEST MODE FOR CARRYING OUT THE INVENTION

The present invention is then exemplary with reference to the drawings which are clearly directed with respect to all the details of the invention which are not otherwise detailed in the text on the basis of examples without limitation of general invention ideas. Explained in. FIG. 1 shows a cross-sectional view of the drum arrangement of the filter installation machine, and FIG. 2 shows a cross-sectional view of the starting point of the transition of the partially bonded components.

【0045】

In the drawings, the same elements have the same code, apart from each new introduction. FIG. 1 is a cross-sectional view of the device 30 of the present invention comprising a plurality of drums, as is formed in, for example, a filter installation machine. The transport means of the device 30 related to the process of the present invention includes a suction roller 2 that circulates in the direction of the arrow 1, and the coupling flakes 3 covering the outer surface of the roller 2 are supplied at predetermined division intervals. This predetermined division interval is given by the length of the bonding flakes 3. The ends of each of the coupling flakes 3 in the transport direction (arrow 1) are connected to the suction roller 2 by one edge 4. The coupling flakes 3 are arranged on the holding member 28 of the suction roller 2 and are held by the holding member 28 by the suction air opening 12.

【0046】

Further, each holding member 28 possesses an asymmetrically arranged recess 13, which accommodates a cigarette mouthpiece group 9 (see below). A further related transport means of the device 30 is formed as a bucket drum 6, which rotates in the direction of the arrow 7 and equips the movable bucket arm with a drum bucket 8. A transmission device comprising a movable arm for rod-shaped articles is disclosed, for example, in German Patent No. 3137223.

【0047】

Each drum bucket 8 receives one cigarette mouthpiece group 9. The width of the cross section of the drum bucket 8 has been increased in order to change the position of the mouthpiece group 9 in the drum bucket 8. Further, the drum bucket 8 has a holding shoulder 21 in the center and accurately receives or changes the position of the cigarette mouthpiece group 9. Optionally, the recessed surface of the drum bucket 8 is removed or grooved.

【0048】

The combined flakes 3 and the drum bucket 8 have the same division spacing to receive the cigarette mouthpiece group 9 upon delivery of the bonded flakes 3. Further, the drum bucket 8 is measured larger than the diameter of the cigarette mouthpiece group 9 and includes a suction air opening 11 for holding the cigarette mouthpiece group 9.

【0049】

During the synchronous rotation of the suction roller 2 and the bucket drum 6, the coupling flakes 3 and the drum bucket 8 are moved to each other and gathered. When the bonded flakes 3 are assembled with the cigarette mouthpiece group 9, the mouthpiece group is brought close to the recess 13 of the holding member 28 and accommodated in the recess 13. Since the suction air is blocked by the front suction air opening 12 in the transport direction 1 of the holding member 28 while being housed in the recess 13 of the cigarette mouthpiece group, the front end of the coupling flakes 3 is placed around the cigarette mouthpiece group 9 and the mouthpiece Combined with the group. By this procedure, the front end of the binding flakes 3 is partially bonded to the other tobacco article component 9.

【0050】

The length of the anterior portion of the coupling flakes 3 on the retaining member 28 is measured so that this anterior portion of the coupling flakes 3 is almost completely pushed into the indentation 13 especially when the cigarette mouthpiece group 9 is housed in the indentation 13. Has been done.

【0051】

Next, the partially bonded or partially coated components 3 and 9 are moved in the direction from the suction roller 2 to the delivery drum 18. Partially covered components 3 and 9 consisting of the combined flakes 3 and the cigarette mouthpiece group 9 are moved along the flakes guide 24. The flakes guide 24 prevents the flakes 3 from separating from the partially covered mouthpiece group 9.

【0052】

Partially covered combinations 3 and 9 consisting of the combined flakes 3 and the cigarette mouthpiece group 9 are supplied to the roll star 25 along the flakes guide 24 according to FIG. 1, and the roll stars are star-shaped on the outer surface as a rotating body. Has a contact surface 26 arranged in. The division interval of the contact surface 26 of the roll star 25 is (approximately) larger than the division interval of the drum bucket 8 in the suction roller 2 and the division interval of the holding member 28 of the suction roller 2. The contact surface 26 has a higher peripheral velocity than a bucket arm with a drum bucket to carry out the position movement.

【0053】

Contact surface 26, to produce a repositioning of the components 3,9 which contact surface 26 is partially coated in the depression 8, the depression 8 same are synchronize. Roll star 25 exerts a (small) relative acceleration of partially coupled components 3 and 9, so component relocation is performed in depression 8. The relative position of the cigarette mouthpiece group 9 is changed to the free end 17 of the connecting flakes of the indentation 8.

【0054】

Since the division interval between the drum recesses 8 is shortened at the same time as or after the position change of the partially bonded components 3 and 9, the drum recess 8 has a shortened interval in the roll drum 18. Since the spacing between the drum dents 8 is further increased after the partially bonded components 3 and 9 are delivered to the roll drum 18, the partitioning interval in the suction roller 2 further matches the partitioning interval of the bonded flakes 3.

【0055】

The roll drum 18 is a partially coated combination 3 and 9 consisting of a coupling flakes 3 and a cigarette mouthpiece group 9 is transferred to a roller portion (not shown here) in the direction of arrow 19 in this roller portion. For example, a roll passage is formed between the roll stand and the outer circumference of the roll drum 18. Since the roll surface of the roll table is significantly longer than the peripheral surface of the cigarette mouthpiece group 9, this surface is wound several times and combined with the bonding flakes 3. Optionally, the wrapping can be performed by a belt instead of a roll stand, as shown, for example, in German Patent Application Publication No. 19857576.

【0056】

FIG. 2 illustrates the initiation phase of the transition of the invention of the partially coupled components 3 and 9 by the repositioning member in the form of roll star 25. Roll star 25 possesses a start plate 27 with protrusion 29, which is related to the transport direction of drum 6 during synchronous rotation of roll star 25 and bucket drum 6, where protrusion 29 is a mouthpiece group. It contacts the cigarette mouthpiece group 9 from the rear until it contacts 9.

【0057】

Since the roll star 25 rotates at an angular velocity (approximately) faster than the drum 6, the protrusion 29 passes it to the depression 8. As a result, the acceleration is extended to the components 3 and 9 partially bonded by the protrusion 29, so that the cigarette mouthpiece group 9 further rotates to the transport bucket 15 of the recess 8. As a result, the edge 4 of the bonding flakes 3 is located in the bucket 15. The free end of the connecting flakes 3 placed on the (posterior) mandrel 14 of the indentation 8 and supported by this mandrel remains constant at this length during this (rotational) movement of the mouthpiece group 9.

【0058】

To ensure that the partially coupled components 3 and 9 are transferred to the bucket 15, the roll star 25 has an inwardly curved contact surface 26 adjacent to the protrusion 29, which is the roll star. During the rotation of 25, it comes into contact with the partially bonded components 3 and 9 for a short time. In particular, the contact surface 26 has a zigzag or grooved surface.
