Description

The invention relates to a device for producing filters of the tobacco processing industry from a filling material and a wrapping around this

Covering material, wherein the device comprises a feed unit for feeding the

Filler material, another feed unit for feeding the wrapping material with a gluing unit for applying glue to the wrapping material, a format for transferring the wrapping material around the filling material and a format tape for

Transport the glued wrapping material together with the filling material in

Has transport direction to the format.

Such devices for the production of filters of the tobacco processing industry are known from the general state of the art. To make a secure connection between the filler material and the shell material, it requires one

Applying glue to the inside of the wrapping material. Beleimungseinheiten are known from the prior art, which can apply glue on the shell material. The source of the wrapping material, the so-called Bobine, is usually arranged below the format tape. The wrapping material can in principle be supplied differently. In the prior art, the wrapping material is often fed by means of a feed unit for feeding the wrapping material to the format tape. Such a feed unit may have a plurality of pulleys and a drive.

By means of a known from the prior art Unterbeleimung or

Side gluing is the gluing material between the reel and the format tape glued. The Unterbeleimung is characterized by the fact that the wrapping material is passed above the gluing unit, while the glue through a

Gluing unit is applied to the shell material. In side gluing, the wrapping material is passed vertically past the gluing unit. The glue is applied horizontally by the gluing unit to the wrapping material. Both the known sub-gluing and side gluing, as they

For example, the documents DE 10027955 and DE 198 07 129 AI are to be found, have serious disadvantages. The glue is applied in each case not in the direction of acceleration due to gravity, but in the side gluing at a right angle to the gravitational acceleration and in the sub-gluing even largely opposite to the direction of gravitational acceleration. This is one

Pollution of the gluing unit and the environment can not be completely ruled out. This is especially true in a contactless internal gluing.

The Unterbeleimung and side gluing also cause another serious disadvantage. To this end, it should be noted that the glued shell material is transported on the format tape in such a way that the applied glue points upwards so as not to come into contact with the format tape as such, but expediently in contact with the shell material. If the glue required for this purpose is applied by means of a sub-gluing or side gluing, the glued enveloping material is to be deflected by at least 180 ° or by at least 90 °. The deflection is ensured in the prior art usually by one or two pulleys, which are over a wrap angle of 90 ° or more in contact with the glued shell material. In this type of deflection, however, liquid or viscous glue is often thrown off the wrapping material. The areas of the wrapping material which therefore encounter the filling material without or with too little glue can not securely fasten the corresponding filling material. The same applies analogously to a longitudinal seam. In addition, there is a risk that the glue thrown away hits other device elements, which in particular can clog the area between the gluing unit and the format, so that the wrapping material can not be transported unhindered to the format. A particularly serious consequence is a rupture of the wrapping material, since in this case the entire device must be stopped. A corresponding standstill of the device may lead to very high downtime costs.

It is therefore the object of the present invention to provide a simple and compact apparatus for the production of filters of the tobacco processing industry, which ensures a secure bonding of the shell material with itself and / or with the filler.

The object is achieved by a device of the type mentioned above in that a substantially downwardly directed outlet opening of the

Gluing unit in the transport direction in front of the format, is arranged below a transport plane defined by the format band and above the wrapping material to be glued to deliver the glue directed substantially downwards. The transport direction is the direction in which the glue is glued

Covering material is transported together with the filling material by means of the format tape to the format. The format is known from the prior art

Abbreviation for a device for transferring the wrapping material around the filling material. According to the invention, at least the outlet opening of the

Gluing unit arranged in the transport direction in front of the format. Thus, the geometric assignment of the format and the outlet opening of the gluing unit is determined. "In the transport direction in front of the format" is thus to be understood as an indication of place Since the plane of transport is a plane in the mathematical sense, it extends beyond the area of the format strip, and according to the invention, at least the substantially downward exit opening of the gluing unit is arranged below the transport plane. Overall, it is thus ensured in a surprisingly simple and reliable manner that the glue can be applied particularly precisely to the wrapping material, because the glue is transferred from the gluing unit to the wrapping material substantially in the direction of acceleration of the earth of the glue and an associated, imprecise application of the glue on the wrapping material are thus prevented. In addition, the arrangement of the gluing unit makes it possible for each of the deflecting means serving to guide the glued enveloping material to be guided,

In particular deflection rollers, the glued wrapping material in each case by less than 90 ° and deflect the glue applied to the shell material by the

Deflection means or pulleys is dropped. This is a surprisingly simple and compact way a device for the production of filters of tobacco created processing industry, which ensures a secure bonding of the shell material with itself and / or with the appropriate filling material.

An advantageous embodiment of the device for the production of filters of the tobacco-processing industry is characterized in that substantially the entire gluing unit in the transport direction in front of the format and below the

Transport level is arranged. Thus, the filling material can be fed freely to the format above the transport plane. Due to the simple feeding of the filling material and the wrapping material, the overall length of the device for producing filters can be kept particularly short. Overall, the device for producing filters by this embodiment variant is particularly compact.

An advantageous embodiment of the device for producing filters of the tobacco-processing industry is characterized in that the format band has a deflection roller on the input side and that at least one further deflection roller for guiding the shell material is arranged in the transport direction in front of the deflection roller and below a transport plane defined by the format band , where the

Beleimungseinheit is arranged on one or between two of the pulleys.

According to the advantageous embodiment, at least one further deflection roller is arranged in the transport direction in front of the deflection roller of the format band. Thus, the geometric assignment of the deflection roller of the format strip and the at least one further deflection roller is determined. "In the transport direction in front of the deflection roller" is thus to be understood as a location indication. Thus, a device for the production of filters of the tobacco-processing industry is created in a surprisingly simple and compact way, the secure bonding of the shell material with itself and / or with the corresponding filler

guaranteed. For each of the pulleys used to guide the glued envelope material directs the glued shell material in each case by less than 90 °. This ensures that the glue applied to the wrapping material is not thrown off by the deflection rollers. In addition, the duration of the movement direction change is limited by the limitation of the wrap angle. Of the

Wrap angle gives the contact area between the respective deflection roller and the shell material in angular degrees, in which the shell material is in contact with the corresponding deflection roller. Also, due to the limited duration of the change of motion, the glue applied to the wrapping material is not thrown off by the deflecting rollers. The applied glue remains on the

Covering material, so that the shell material can be securely bonded to itself and / or with the filler.

An advantageous embodiment of the device for producing filters of the tobacco-processing industry is characterized in that the deflection rollers are arranged such that all deflection rollers between the gluing unit and the format in each case over a wrap angle of a maximum of 70 degrees in contact with the shell material , By limiting the wrap angle, the change in the direction of movement and the duration of the movement direction change of the glue applied to the wrapping material is limited, so that the glue is not thrown off by the deflection rollers.

An advantageous embodiment of the device is characterized in that at least two deflection rollers are arranged between the gluing unit and the format. This makes it possible in a particularly simple manner to ensure that a movement direction change on each of the rollers between the gluing unit and the format is so small that the glue is not thrown off. Because the entire movement direction change between the gluing unit and the format is distributed to the at least two pulleys and is correspondingly small.

An advantageous embodiment of the device is characterized in that all pulleys between the gluing unit and the format each have at least a radius of 12.5 mm. The size of the radius of the deflection rollers prevents particularly large acceleration values from acting on the glue, so that the glue remains on the corresponding covering material despite deflection by the deflection roller. In order for a secure bonding of the enveloping material can be ensured with itself and / or with the filler. A further advantageous embodiment of the device is characterized in that all pulleys between the gluing unit and the format are arranged or formed such that the centrifugal force caused by each of these pulleys acting on the glue is less than an adhesive force of the applied glue. The centrifugal force is the force that acts on the glue during deflection by a deflection roller. The adhesive force is the force that must be used to separate the glue from the shell material. The adhesive force thus depends strongly on the material properties of the glue and / or the wrapping material. In this way, the deflection rollers between the gluing unit and the format can be arranged in their geometric positions and / or configured in their radius such that the centrifugal force is less than the corresponding adhesive force, so that the applied glue is prevented from being dropped by the rollers , For a secure bonding of the enveloping material is guaranteed with itself and / or with the filler.

A further advantageous embodiment of the device is characterized in that the deflection rollers are arranged directly in front of and behind the gluing unit in such a way that the shell material at an angle between 20 ° and 90 ° to the solder on the

Gluing unit to pass. For clarification: At an angle of 90 ° to the solder, the wrapping material was led horizontally past the gluing unit. An angle range between 20 ° and 90 ° is characterized by an advantageous compromise, which makes it possible to design the device for producing filters of the tobacco-processing industry in a particularly compact manner and to ensure the most precise possible application of the glue to the enveloping material. Because in the aforementioned angular range of the glue is not applied against the acceleration of gravity on the shell material. In addition, said angular range offers an advantageous design possibility for integrating the gluing unit as such in a particularly compact manner into the device according to the invention.

A further advantageous embodiment of the device is characterized in that the outlet opening of a, in particular frusto-conical nozzle of the

Glueing unit is aligned for lining the wrapping material at least substantially parallel to the applied wrapping material. In a surprisingly simple way so that the nozzle can be particularly close to the leading to wrapping material position. Furthermore, this ensures a particularly precise application of the glue on the shell material. Because the distance to the leading to wrapping material can be chosen particularly small in this way. If this distance is particularly small, then also the foreign influence is reduced, like

for example, the acceleration of gravity, on the order process. Thus, this embodiment is characterized by a particularly safe and / or precise application of the glue on the shell material.

A further advantageous embodiment of the device is characterized in that the gluing unit, the nozzles and / or the outlet opening are spaced from the enveloping material in order to glaze contactlessly the enveloping material. Such an embodiment of the device ensures a particularly safe and precise application of the glue on the shell material. Because the spacing of the gluing unit and / or the nozzle from the wrapping material prevents the gluing unit or the nozzle from blurring an already applied glue or, in other words, changing it in its applied position. Thus, an uncontrolled blurring and / or changing the position of the glue on the wrapping material is particularly easy and effectively prevented. The avoidance of contact also does not abrade the wrapping material and it does not build up any soiling on the gluing unit which could be carried along in an uncontrolled manner, thereby causing blockage of the format.

Further advantageous and / or expedient features and configurations emerge from the subclaims and the description. A particularly preferred embodiment will be explained in more detail with reference to the accompanying drawings. In the drawings show:

Fig. 1 is a schematic representation of the apparatus for producing filters of the tobacco processing industry and

Fig. 2 shows an enlarged section of the device, the pulleys

between the gluing unit and the format. In Fig. 1, a machine 2 for the production of filter rods is shown. This machine 2 usually has two main groups, namely a device for filter production 4 and a device for Towaufbereitung 6 on. For continuously removing an endless filler strip 8 from a filter pad 10, the device 6 for the preparation of tow comprises a deflection roller 12 and a pair of rollers 14. The pair of rollers 14 is driven by a main drive 16 via belt drives 18, 20 and a gear 22. The ratio of the transmission 22 is variable by means of a Verstellmo- sector 24. By means of the pair of rollers 14, the filter material 8 is pulled over the guide roller 12 from the filter pad 10. In this case, the filling material 8 passes through two air nozzles 26, 28, which for the preparation and loosening of the tissue of the

Fill material 8 serve. The pair of rollers 14 are followed by two further pairs of rollers 30, 32. These pairs of rollers 30, 32 are by means of the main drive 16 via belt drives 18, 34 drivable. Thus, the pairs of rollers 30, 32 are also used for transporting and processing the filling material 8. Between the pair of rollers 30 and the pair of rollers 32, an application unit 36 for applying plasticizer to the filling material 8 guided between the pairs of rollers 30, 32 is shown. The plasticizer-ordered filling material 8a is directed via the pair of rollers 32 to the device 4 for filter production. In addition, in Fig. 1, the device 4 for the production of filters of the tobacco processing industry from a filler material 8b and a wrapping this wrapping material 42 is shown, wherein the device 4 is a feed unit 41 for

Feeding the filler material 8b, another feed unit 43 for feeding the wrapping material 42 with a gluing unit 44 for applying glue to the wrapping material 42, a format 46 for transferring the wrapping material 42 around the filling material 8b and a format belt 40 for transporting the glued wrapping material 42 together having the filler material 8b in the transport direction T to the format 46. Particularly preferably, the format band 40 has a deflection roller 50 on the input side. The device 4 for the production of filters is characterized in that a substantially downwardly directed outlet opening 76 of the gluing unit 44 in the transport direction T in front of the format 46, below a transport plane E defined by the format belt 40 and above the wrapping material (42) to be glued. is arranged to deliver the glue directed substantially downwards. In order to In a surprisingly simple and compact manner, a device 4 for the production of filters of the tobacco-processing industry is provided, which ensures a secure bonding of the wrapping material 42 to itself and / or with the corresponding filling material 8b. For by means of the device 4 according to the invention and the arrangement of the gluing unit 44, the gravitational acceleration acts to such an extent on the emerging glue that a distraction of the glue and an associated imprecise application of the glue to the enveloping material 42 are prevented. In addition, it is ensured by the arrangement of the gluing unit that the deflecting roller 50, which is preferably used to guide the glued enveloping material, or a different deflecting means 50 deflects the glued enveloping material by less than 90 ° and the glue applied to the enveloping material 42 does not pass through

Deflection rollers 50 and deflection 50 is dropped.

An advantageous embodiment of the device 4 for the production of filters of the tobacco-processing industry is characterized in that the format strip 40 on the input side, the guide roller 50 and that in the transport direction T before the guide roller 50 and below defined by the format band 40

Transport level E at least one further guide roller 54 for guiding the

Cover material 42 is arranged, and wherein the gluing unit 44 is arranged on one or between two of the deflection rollers 50, 54.

The filling material 8b is usually a so-called tow. The tow or filling material 8b comprises a filter fabric. This filter fabric is preferably sprayed with plasticizer. The wrapping material 42 is mostly thin-walled paper. The wrapping material 42 is guided by means of the feed unit 43 for feeding the wrapping material 42 to the format strip 40. Such

Feeding unit 43 may have a plurality of the guide rollers 54, 72. The filling material 42 is guided to the format belt 40 by means of the further feed unit 41 for feeding the filling material 8b. Such a feed unit 41 is for example a

Inlet funnel 38.

It is known from the prior art that a filter has a plurality of different adhesive connections. One of these adhesive joints is the adhesive bond at the so-called seam of the wrapping material 42. The wrapping material 42 is basically wider than the casing circumference of a filter, so that the wrapping material 42 overlaps in the longitudinal direction of the filter at its periphery. At this overlap, the wrapping material 42 is glued together, so that here is an adhesive bond to the so-called seam. Furthermore, a filter has an adhesive bond between the filler material 8b and the wrapping material 42.

The production of a glue connection is fundamentally differentiated according to two types. This is on the one hand the so-called hot glueing. This method uses hot glue, which cures very quickly when cooled. The second method is the so-called cold gluing. Here cold glue (glue with room temperature) is used. This glue is characterized by the fact that the glue initially retains its viscosity and / or other properties even after being applied to a surface to be glued. A transition from a liquid or viscous state in which the glue is applied to a solid state in which the glue can combine several materials requires a certain amount of time. The invention is therefore particularly advantageous for cold gluing.

The format 46 is the short term known from the prior art for a device for transferring the wrapping material 42 around the filling material 8b. The format 46 preferably has longitudinally conical converging sidewalls. The exit opening of the format 46 essentially corresponds to that

Cross section of a filter. In this case, the coated by the gluing unit 44 shell material 42 is transported together with the filler 8b in the transport direction T by means of the format strip 40 to the format 46. The format belt 40 is preferably a special embodiment of a conveyor belt. Like a general conveyor belt, the format belt 40 can also have a deflection roller 50 on the input side. The input side of the format band 40 is the side at which the glued shell material 42 and the filler material 8 b strike the format band 40. Thus, two different materials impinge on the input side of the format strip 40. Since the filling material 8b and the wrapping material 42 are finally connected to one another only by the format 46, the filling material 8b and the wrapping material 42 are directed to the format strip 40 in separate ways. It has been established in the prior art that the Covering material 42 is guided from below to the format tape 40, whereas the filler 8b is laterally brought to the format tape 40 in order to obtain the most compact apparatus for the production of filters. The format band 40 defines the transport plane E. Preferably, the glued shell material 42 is combined in the transport plane E with the filler material 8b.

In addition, the glued shell material 42 can be transported together with the filler material 8 b by means of the format strip 40 in the transport plane E to the format 46.

In the embodiment shown in FIG. 1, the glued shell material 42 is deflected only by the input-side deflection roller 50 of the format strip 40. However, further deflection rollers 72 (as shown in FIG. 2) can also be arranged between the gluing unit 44 and the format 46. Each one to lead the glued

Hüllmaterials serving pulleys 50, 72 can deflect the glued shell material in each case by less than 90 °. This ensures that the glue applied to the wrapping material 42 is not thrown off by the deflection rollers 50. Further deflection rollers between the gluing unit 44 and a reel 56 can also be deflected by larger angles, for example 90 ° or more, since the enveloping material in this area is still free of glue.

In the embodiment of the device 4 for producing filters of the tobacco processing industry shown in FIG. 1, only the input-side deflection roller 50 of the format strip 40 is arranged between the gluing unit 44 and the format 46. So that the input-side deflection roller 50 of the size band 40 is in contact with the glued shell material 42 over a wrap angle of less than 90 °, the further deflection roller, in this case the deflection roller 54 directly in front of the gluing unit 44, is also in front of the gluing unit

Input side pulley 50 of the format strip 40 is arranged. This information is to be understood in a geometric sense. In other words, that is

Input-side guide roller 50 of the size strip 40 is arranged in this embodiment in the transport direction T behind the further guide roller 54. To one

To ensure wrap angle of less than 90 °, this is another Guide roller 54 advantageously also arranged below the transport plane E. Such an arrangement of the deflection rollers 50, 54 limits the contact of the glued enveloping material with the respective deflection roller 50 and restricts a change in the direction of movement of the glue applied to the enveloping material 42. Basically, the maximum wrap angle to the respective radii of the pulleys, the adhesive force of the glue and / or the

Movement speed of the wrapping material 42 to be adjusted. The smaller the maximum wrap angle, the lower the effect of the

Centrifugal forces acting on the glue applied to the wrapping material. A correspondingly smaller wrap angle of the wrapping material 42 can be ensured by a plurality of between the gluing unit 44 and the format

Deflection rollers 50, 72 are arranged, as shown for example in Fig.2.

An advantageous embodiment of the device for producing filters of the tobacco-processing industry is characterized in that substantially the entire gluing unit 44 is arranged in the transport direction T in front of the format 46 and below the transport plane E. Thus, the filler 8b can be freely supplied above the transport plane E format 46. Due to the simple supply of the filling material 8b and the wrapping material 42, the overall length of the device 4 for the production of filters can be kept particularly short. Overall, the

Device 4 for the production of filters by this design variant is particularly compact.

An advantageous embodiment of the device 4 for the production of filters of the tobacco-processing industry is characterized in that the deflection rollers 50, 54, 72 are arranged such that all deflection rollers 50, 72 between the gluing unit 44 and the format 46 each have a wrap angle α , ß of a maximum of 70 degrees with the shell material 42 are in contact. Each of these deflection rollers 50, 72 can deflect the glued shell material over a certain angle of wrap, which does not exceed the maximum permissible angle of wrap. The maximum wrap angle is particularly preferably 65 °, 60 °, 55 °, 50 °, 45 °, 40 °, 35 °, 30 °, 25 ° or 20 °. It is thus possible that between the gluing unit 44 and the format 46 two deflection rollers 50, 72 or even further deflection rollers are arranged. Each of these pulleys 50, 72, the glued shell material 42, for example, deflect by 40 °. In this case, the input-side deflection roller 50 of the format strip 40 would deflect the glued shell material 42 by 40 °. Although the glued shell material 42 is deflected by both deflection rollers 50, 72 by a total of 80 °, the glue applied to the shell material 42 is not thrown off by the deflection rollers 50, 72. In order to prevent a quasi-continuous deflection of the glued envelope material 42, the deflection rollers between the gluing unit 44 and the format 46 are preferably spaced from each other. An advantageous embodiment of the device 4 for the production of filters of the tobacco-processing industry is characterized in that all pulleys SO, 72 between the gluing unit 44 and the format 46 each have at least a radius of 8, 10, 12.5, 15, 17, 5, 20, 25 or 30 mm. Due to the correspondingly high radius ensures that the axes of rotation of the guide rollers 50, 72 are spaced from each other. Furthermore, a large radius of the deflection rollers 50, 72 ensures that the effect on the glue by a deflection

Centrifugal force is lower than with a pulley with a smaller radius, assuming a constant Umschlmgungswinkels. The wrapping material 42 and the filling material 8b, which have been securely glued according to the invention, are guided through the format 46 by means of the format strip 40 such that the glued wrapping material 42 surrounds the filling material 8b and thereby forms an endless filter strand. This filter strand can then pass through a setting unit 60, in which the glue at least partially sets. By means of the binding unit 60, the required temperature for setting the glue can be controlled. From the binding unit 60, a filter strand 58 is transported to a blade unit 62, which continuously cuts the filter strand 58 into filter rods 64. The filter rods 64 are then transferred by an accelerator 66 in a Ablegertrommel 68. From the discharge drum 68, the filter rods 64 pass via a depositing belt 70 to a further processing device (not shown).

2 shows an enlarged detail of the device 4 for the production of filters of the tobacco-processing industry. Here are between the gluing unit 44 and the format 46 more, namely two pulleys 50, 72 arranged in such a way that the pulleys 50, 72 between the gluing unit 44 and the format 46, the glued shell material 42 each deflect over an actual wrap angle, which is less than the maximum wrap angle of 70 ° is. The deflecting rollers 50, 72 between the gluing unit 44 and the format 46 are, on the one hand, the input-side deflecting roller 50 of the format strip 40 and a further deflecting roller 72. By means of this further deflecting roller 72, the glued enveloping material 42 is deflected over a wrap angle α. Furthermore, the glued wrapping material 42 is deflected by means of the input-side deflection roller 50 of the format strip 40 over a wrap angle ß. Both deflection angle α, ß are smaller than the maximum Umschlmgungswinkel of 90 ° or 70 °.

In order to glue the wrapping material 42 at least substantially from above, the gluing unit 44 is arranged according to the invention above the wrapping material 42. For this purpose, the guide roller 54 directly in front of the gluing unit 44 and the

Guide pulley 72 may be arranged directly behind the gluing unit 44 so as to guide the wrapping material 42 past the gluing unit 44 at an angle γ between 20 ° and 90 °, preferably between 50 ° and 80 °, particularly preferably 70 ° , This ensures in a surprisingly simple and safe way that the glue is applied particularly precisely to the wrapping material 42.

The gluing unit 44 usually has a nozzle 77, which is designed and configured for applying the glue to the wrapping material 42. A further advantageous embodiment of the device 4 for producing filters of the tobacco-processing industry is characterized in that an outlet opening 76 of a, in particular frusto-conical, nozzle 77 of the gluing unit 44 is aligned at least substantially parallel to the enveloping material 42 to be applied to the wrapping material 42 is. In this way, the gluing unit 44 can be positioned particularly close to the wrapping material 42 to be led past.

A further advantageous embodiment is characterized in that the gluing unit 44, the nozzle 77 and / or the outlet opening 76 are spaced from the shell material 42 in order to glue the shell material 42 contactless. This will be one ensures particularly safe and precise application of the glue on the shell material.
