Definitions
- the present invention relates to a device for embossing and / or perforating films for tobacco products, comprising a pair of embossing rollers, wherein one of the embossing rollers has teeth for perforating the film, according to claim 1.
- film here comprises a cigarette enveloping one Foil, eg made of paper that may be preprinted or embossed, which may have so-called LIP (Low Ignition Propensity) zones or stripes or is entirely covered by a fire-retardant substance, and the tipping paper, the so-called tipping paper wrapped around the cigarette filter becomes.
- LIP Low Ignition Propensity
- Prior art embossing devices with rollers are primarily used for embossing packaging films, e.g. for the food industry, the pharmaceutical industry and in particular for the tobacco industry.
- devices with embossing rollers have been used for over 30 years for embossing packaging films, in particular so-called innerliners, these innerliners being provided not only with decorative effects but also with authentication features.
- the paper content is stabilized such that the film can be processed without difficulty in the subsequent packaging system.
- the term tobacco product manufacturing machine is understood to mean a device for wrapping individual pieces of tobacco products such as cigarettes, this machine being referred to in this application as "maker".
- the embossed film can be direct or indirectly via a robot to the maker. Both methods are referred to as online methods. From there, the cigarettes get into a tobacco packaging machine, also called “packer” for short, in which a number of cigarettes are packed. In the present application, only the maker following the perforation is interested.
- the perforations can be attached only in certain places, eg. B. outside the LIP zones, which cause the extinction of the cigarette after a certain time.
- emphasis is placed on the fact that the film is not weakened in such a way by the perforations that a tearing of the same can be caused on further processing.
- the long-known teeth are used in Pinup constellation, the teeth are disclosed as pyramidal.
- the Wo application also discloses a control unit which inspects the film after embossing to determine various properties of the embossed film and to control the mutual pressure of the embossing rolls and thus the penetration depth of the teeth into the paper in terms of tear strength.
- Fig. 1 shows a possible flow chart for the embossing and perforation of cigarette wrapping films, currently mainly made of paper or so-called Tippingfolien, hereinafter called "film”.
- any embossing or printing patterns as well as the hole patterns must be placed in local dependency on these LIP zones. But even if the entire film is already completely treated with a fire-retardant substance, the possible embossing or printing patterns and the hole pattern must be generated at certain points. In this case, suitable marking, so-called “eye marks”, may already be present or be applied continuously. These zones, print patterns or other markings are detected by a position sensor. The various markings, patterns and zones on the film, if applicable, are summarized by the term "texture".
- the film to be processed 1 first passes through a first position sensor 4, then optionally a known embossing unit 2 with here three embossing rollers 2A, 2B and 2C, then a synchronization unit 3 for detecting the relative position of the power stroke A1 of the embossing unit 2 with respect to the process cycle P. the maker. Subsequently, the film passes through a first buffer unit 7, a second position sensor 4A for detecting embossing and printing structures, a perforation device 5 and then a quality tester 6 for detecting the perforated pattern with pressure-regulating sensor 18, then via a second buffer unit 7A either directly or via a robot to get to the Maker not shown.
- the embossing unit 2 may be a printer before, after or instead of switched, the control is analogous to the control of the embossing unit is formed.
- the process cycle P can be defined, for example, by a length section of the film 1 to be fed per unit time of the maker, to which the working cycle A1 of the embossing unit 2 must be coordinated during the pretreatment of the film 1.
- This corresponds to a positionally accurate arrangement of the impressed by the embossing unit surface structure on the respectively to be supplied longitudinal portion of the film.
- the surface structures may be one or more logos created by removing or changing teeth on a roll or on multiple rolls. It can also be printed patterns.
- the embossing unit 2 may also include a male-female embossing roller pair.
- the synchronization unit 3 contains a determination device 8, this for example, a continuous optical detection of the position of the surface structure may have been imprinted in the embossing unit 2 on the film 1. The detection takes place on the transport path between the embossing unit 2 and the perforation device 5.
- the determined working cycle 1 is adjusted in a positioning device 9 to the process cycle P.
- a manual and / or automated adjustment method is conceivable.
- the embossing roller of embossing unit 2 can be temporarily decoupled from the drive so as to extend the transport path of the film 1 by a desired amount, which is then in line with the process cycle P.
- the need for extension of the transport path of the film is collected by a buffer unit 7, which is arranged behind the embossing unit 2.
- the device additionally comprises a control unit 10.
- This can e.g. continuously carried out optically by means of a lamp which is formed in the manner of a stroboscope at regular time spaced light incidents on the film.
- the irradiation frequency preferably corresponds to the process cycle P.
- optical synchronization In addition to the optical synchronization, other means are conceivable, for example a visual detection or a manual adjustment of the positioning device, by which the working clock A1 of the synchronization unit 3 with the Working cycle A2 of the control unit 10 is synchronized.
- electronic synchronizing signals or also mechanical synchronizing means may be used, such as a plurality of toothed wheels and / or belts, which may be equipped with an angle and / or position adjustment mechanism.
- the information thus determined is further used in a positioning device 12 in order to adapt the working cycle A2 to the working cycle A1 such that the formed perforation patterns 25 have the desired relative position on the film 1E.
- the positioning device 12 may be configured to manually and / or automatically adjust the circumferential relative position of the driven perforation roller 13 with respect to the film 1.
- the markings 40 can serve on the embossing rollers.
- a coupling for uncoupling the perforation roller 13 of the roller drive 15 is conceivable. This additionally allows a change in the relative position of the perforation pattern 25 on the film 1 as required or depending on the process.
- the comparison device 11 can also be used to detect the relative deviation of the working cycle A2 from the process cycle P, for a renewed check of the synchronization with the subsequent enveloping process. Furthermore, indirect conclusions can be obtained in this way on an unwanted deviation of the power stroke A2 with respect to the power stroke A1, since the power stroke A1 is already synchronized by means of the synchronization unit 3 with the process cycle P.
- the second buffer unit 7A is provided for changing the transport path of the film 1 according to need when the positioning device 12 engages after the perforation unit 5.
- both the spacing of the two perforation rollers 13 and 14 and the pressure of one roller on the other roller are controlled to produce the desired perforation patterns.
- the suitable pressure transducer 16 is controlled by a control unit 17. From the scheme of Fig. 1 shows that the control unit 17 from the process cycle P and a signal from the one or both sensors 4, 4A is applied to control the pressure transducer 16.
- embossed film 1E In a simplified device, it is possible to allow embossed film 1E to reach the maker after the perforating device, but it is advantageous and indispensable for many applications to control the hole pattern after being processed by the perforating rollers and possibly to engage the control loop.
- a quality tester 6 with pressure control sensor 18 is arranged after the pair of perforated rollers and before the second buffer unit 7A.
- the quality checker unit 6 is connected to the control unit 17, via the pressure transducer 16 the To control perforation roller pair. In addition, this unit 6 is connected to an evaluation unit 19.
- the quality control unit further includes a template 20 (template), which is present here in electronic form.
- a film 1E with perforation zones 72 is shown, leaving the LIP areas between and adjacent thereto.
- LIP stands for "low ignition propensity", with fire-retardant material being applied to the inner side of the film. They may also be LIP zones that have been applied before embossing. There are no LIP areas before perforating Tipping paper, but there may be embossed or printed areas.
- a cigarette 70 enveloped by a foil 1E is shown, on which the perforation zones 72 and the LIP regions 71 lying between them as well as the mouthpiece 73 and the filter 74 can be seen.
- the quality inspector 6 is in Fig. 2 explained in detail. Bottom right, two of the possible hole patterns of films 1A and 1B, patterns 25A and 25D, are seen.
- a signal from the control unit 17 passes to a laser beam 21 and from there to an imaging optics 22 and to a measuring mask 23.
- the measuring beam 22M transilluminates the film and there the pattern 25A or 25D of the embossed film 1E, its image to a high-speed image sensor 24th passes and there to a memory 26, where it is stored.
- the correlation detector 27 receives the image of the hole pattern 25A or 25D and the corresponding pattern of the original 20, from where it passes to an evaluation unit 28 with Ausncealgorismus, which also includes a computer. From there, the result is transmitted to the evaluation unit 19.
- the computer unit 28 is connected to the control unit 17.
- the template 20 serves both as a template for the production of Perforationsorgane on the embossing rollers and to control the embossed hole pattern on the film. As a result, a reliable and easy-to-check authentication of the enveloped by such films cigarettes or other tobacco products are made.
- control unit 17 is equipped to regulate the procedure if the different zones change, with different parameters being able to influence it.
- each one of the rollers is driven by a belt drive 29 and this drive is transmitted via the gears 30 and 31 to the other roller.
- Both the drive 19 and the synchronization gear 30, 31 can be replaced by suitable electronic means.
- the patrone roller 13A has pyramidal teeth 33 with a square outline, wherein the schematically drawn teeth are arranged here in each case three rows. The distance D of the rows depends on the desired permeability, which depends inter alia on the number and size of the holes.
- the length L of this zone 32 is slightly larger than the width of the film 1.
- the lowering S can be arranged on one or both embossing rollers, in which case the total lowering is the same.
- the stencil roller 14A has recesses 34 associated with the perforation teeth 33 on the stamper roller 13A.
- the recesses 34 are not necessarily inwardly congruent with the teeth 33 and may have shapes and geometric dimensions other than the teeth, as is apparent from the description of FIG Fig. 17 will emerge.
- the Patrizenwalze 13 B in Fig. 4 has tapered teeth 35 while the die roller 14B has associated recesses 36.
- the rest of the configuration of this pair of rollers is the same as the pair of rolls of Fig. 3 ,
- roller pair 13C and 14C according to Fig. 5 has the same conical teeth and recesses 35 and 36 as shown Fig. 4 with the difference being that both rolls each have a lowered zone 32 and 32M, wherein the reductions S2, S3 need not be the same as in the preceding examples.
- rollers 13D and 14D have no lowering.
- the roller pair 13E and 14E of Fig. 7 has teeth, or recesses 37 and 38, which are pyramid-shaped and have a triangular outline.
- the Patrizenwalze 13E has a depression S1.
- roller pair 13F and 14F of Fig. 8 has the tapered teeth, or recesses 35 and 36, wherein none of the rollers has a depression.
- Training variant are the points 39, at which the teeth are arranged at the die roller 13F, raised. This increase corresponds approximately to the thickness of the film.
- the remaining parts of the roller pair are similar to the roller pair 13B and 14B configured.
- roller pair 13G and 14G according to Fig. 9 is the same as the roller pair according to Fig. 4 with the exception of the position mark 40 on both rollers in order to be able to synchronize the rollers with the process cycle P and the work cycles.
- roller pair 13G and 14G according to Fig. 9 and 13H and 14H according to Fig. 10 The difference between the roller pair 13G and 14G according to Fig. 9 and 13H and 14H according to Fig. 10 is that the positioning mark 40 according to the pair of rollers Fig. 10 after every row of teeth.
- the patrone roller 13B is the same as that Fig. 4 while the die roller 14J has recesses 41 associated with the teeth 35 which are less deep than the associated teeth 35.
- the roller pair 13K and 14K according to Fig. 12 differs from the one according to Fig. 3 in that the teeth 42 have a rectangular and not a square plan. Accordingly, the floor plan of the associated recesses 43 is also rectangular.
- the rectangular teeth 44 and the associated recesses 45 are according to Fig. 13 aligned in their longer extension perpendicular to the longitudinal axis.
- the flanks of both the rectangular and the square teeth may also be arranged at an angle to the longitudinal axis, the for example, may be between 10 ° and 80 °.
- the remaining parts of the two rollers 13L and 14L are the same as above.
- roller pair 13M and 14M according to Fig. 14 differs from the roller pair 13F and 14F according to Fig. 8 in that the male roll 13M has both the raised zone 39 and a sink S4.
- the stencil roller 14A is the same as the pair according to FIG Fig. 3 and the teeth 33 are also the same as on the punch roller 13A. Between the rows of teeth, however, the male roller 13N has contact strips 46, which have the task of tensioning the film. The arrangement is vivid on average Fig. 16 shown.
- FIGS. 17 to 36 show schematized and greatly enlarged in a radial section, the cooperating structures of the male and female rollers. It follows that the recesses corresponding to the raised structures of the male roll are not strictly inversely congruent with the die roll, but may include deviations to a certain extent. In order to better characterize the dimensions and their deviations, are in Fig. 17 some angles and measures indicated. These teeth may be teeth with a square or rectangular outline or tapered teeth or teeth with another, for example triangular, floor plan.
- Both rolls have depressions and a tooth 33, or 35 is drawn on the male roll 13P1, the opposite flanks of which enclose an angle ⁇ .
- the tooth 33 or 35 corresponds to the Recess 34 or 36 in the die roller 13 M1, wherein the opposite edges of the recess enclose an angle ⁇ , where ⁇ is smaller than ⁇ .
- the difference between the two angles is B, the tooth height is DT and the depth of the depression in the matrix is G.
- the distance between the tooth surface and the base of the depression is E, the reduction in the circumference of the male and female rolls is S1 and S2.
- Exemplary dimensions are: tooth height greater than 0.05 mm, typically 0.2 to 0.4 mm, pitch, greater than 0.1 mm, typically 0.1 to 4 mm, Angle ⁇ ⁇ 10 ° to 90 °, Difference ⁇ - ⁇ 0 to 80 ° Reduction S of the circumference, 0.02 to 2 mm wherein the pitch is defined as the distance between two adjacent teeth.
- FIGS. 18 and 19 is highly schematic and enlarges the film 1E shown after embossing and it can be seen that the film is slightly compressed at the edges where no perforating teeth or recesses are present while the film within the rows of teeth is the normal thickness of 20-50 microns having.
- the tipping paper may have a slightly greater thickness.
- Fig. 18 is the male 13P2 below and 13M2 above.
- Out Fig. 18 a variant is shown in which the film was perforated by the teeth 35, while the smaller teeth 35 S only deform the film but not perforate. These deformations also serve better ventilation, since there the film is not tight and thus air permeable.
- Both rolls each have a depression S1, S2.
- the male 13P3 is at the top and the male 14M3 at the bottom.
- the Patrizenwalze 13P3 has a relatively large reduction S3, so that the film is not compressed outside of the teeth.
- the teeth 35VS of the male are relatively small with respect to the other teeth, as are the corresponding recesses 36VS in the female die which serve to deform. As already said, it concerns with the FIGS. 18 and 19 around heavily schematized drawings.
- FIGS. 20A to 20D 4 are given different possible examples of rows of holes, wherein the rows of holes 25A obliquely, the rows of holes 25B rhombus-shaped, the rows of holes 25C perpendicular to the cigarette axis but not of equal length and the rows of holes 25D are also arranged perpendicular to the cigarette longitudinal central axis but equal lengths. Between the rows of holes there are LIP zones.
- FIGS. 21 to 36 are shown schematically each only a Patricitahn and a Matrizenverianaung, in each case alternately a Patrizen-Matrizencru with the male above and the lower die, or vice versa are shown. Since the supplied film is not homogeneous, but structured in thickness and may optionally each have a different surface, one each different structure arise whether the male roller is arranged above or below.
- Fig. 21 shows a Patrizen-Matrizencru with a male 13.21 and a female 14.21. Both the tooth 35.21 and the recess 36.21 have an opening angle ⁇ , ⁇ , which are 60 ° in the present example. Both rollers have a reduction S1, S2, so that a regular embossing is possible.
- the arrow 1 indicates the surface of the cigarette paper. The sum of both reductions is 0.02 mm in the present example.
- the patrix is arranged at the bottom and the die at the top, whereby the effect of the patronage on the paper is reversed, ie from below.
- the male P13.23 and the female M14.23 have the same tooth 35.21 and the same recess 36.21 as in the previous example, but only the male has a depression of 0.02 mm here while the female is not lowered.
- FIG. 24 The male and female are reversible.
- the paper foil is clamped during the punching process.
- the paper is not pinched during the punching process.
- the sum of the reductions, either distributed on both rolls or only on one roll, is 0.14 mm.
- the male part P13.25 has a tooth 35.25 and a recess 36.25, whose opening angle ⁇ , ⁇ is also 60 °. Due to the relatively large reduction of the hole diameter for the same teeth and depressions is smaller than in the previous example. It can be seen that with the size of the reduction at otherwise constant Dimensions of the teeth of the hole diameter can be changed.
- the difference between the FIGS. 25 and 26 and 27 and 28 lies in that the lowering S4, S5, S6 takes place once on both rolls and in the second example only on the Patrizenwalze.
- the paper is clamped again, because the total reduction, whether distributed on both rollers or only on one roller is 0.02 mm.
- the male P13.29 has teeth 35.29, which enclose an angle ⁇ 2 of 45 °.
- the surface structures of the rolls are required in a greater variety, as well as more rationally and, more particularly, more precisely for a substantial improvement of the embossing possibilities and quality and, above all, for use in online processes can be produced. While the accuracy of the prior art could be ensured by etching or by mechanical processing with great effort, this does not apply to the rational and thus faster production of the male-die rollers in a wide variety of Perforationsorgane.
- One solution is to form the surface structures of the rollers of a set independently of each other, ie, that not first the patrone roller and physically dependent on the die roller must be formed. At present, this is conceivable for the required precision and production time preferably when using a suitable laser system, which allows not only Patrizenwalzen but also to produce die rolls rationally, precisely and, above all, very in many different ways and independently of each other.
- An exemplary laser system may include a laser including a deflection unit with a beam splitter and acousto-optic or electro-optic modulators or polygon mirrors.
- the deflection unit and focusing optics and deflecting mirror form a engraving unit which can be linearly displaced in the X-axis. But it can also be provided to move the entire laser device in the X-axis.
- the rotating workpiece is driven by a drive. By combining the linear displacement of the engraving unit and rotation of the workpiece creates a constant helical line, which allows a uniform machining.
- a deflection unit which may include, for example, one or more beam splitters and electro-optic or acousto-optic modulators or one or more polygon mirrors, enables the splitting of the original laser beam into two or more laser beams impinging simultaneously on two or more tracks, but have such a distance from each other that they do not interfere with each other.
- the time interval between the impact of the individual pulses can be chosen so large that a thermal overload does not occur.
- the energy is applied in a very short period of time, allowing for so-called "cold ablation" where the material vaporizes rapidly without unacceptable heating of the adjacent material becomes.
- the undesirable fluid state of the material, the crater edges and Generated splashes can be virtually completely avoided.
- the desired structures are created on a computer that controls the laser system so that it does not matter if a surface structure is created for a punch roll or a die roll.
- a suitable steel, carbide or ceramic is used for example.
- FIG. 37 Two different housing for receiving a pair of embossing rollers are shown.
- a housing 50 is shown in which the male roller 13K and the female roller 14K are received.
- the embossing rollers 13K and 14K have the teeth 42 and depressions 43, respectively FIG. 12 on, like this Figure 37A is apparent. In this example, both rolls have a reduction.
- the housing 50 has two longitudinal sides 51 and two broad sides 52A and 52B, the longitudinal sides each having a window 53.
- the lower embossing roller in the present case the die roller 14K, is pushed in or out for attachment and removal through a corresponding opening in the transverse side 52A and the axle end is rotatably mounted in the other transverse side 52B.
- the storage by needle and ball bearings is known per se.
- the male roller 13 is inserted from the rear invisible opening 53 and fixed in an accurate position.
- this attachment is symbolically represented by a screw 54. Since it is a pair of male and female rollers, whose teeth or depressions are associated with each other, the two rollers must be mounted in a very precise relationship to each other in the housing.
- One of the adjusting means in the direction of the longitudinal axis of the rollers is to produce two precisely aligned adjusting rings 55 on one of the rollers, here the die roller, and on the counter roller an exact central ring 56 which comes to rest between the two rings 55.
- An adjustment possibility in the radial direction consists in the accurate production of the gears 31 and 32, which allow a very accurate radial positioning.
- a pneumatic block 59 On the housing is a pneumatic block 59, which is controlled to precisely adjust the pressure and, derived therefrom, the distance between the two rollers.
- the non-driven roller - here the upper roller - is mounted on its axes in such a way that it is possible to avoid the axes in all three coordinates. This makes it possible to precisely synchronize the teeth and recesses.
- the connecting flange 58 of the axis of the lower roller is visible, on which the lower roller is driven.
- the housing, the embossing rollers and the pneumatic block are the same, and the storage of the lower roller, the die roller, is the same.
- the difference between the two embodiments lies in the storage of the upper, here the Patrizenwalze 13, this storage is shown very schematically.
- the two ends of the axis 57, the upper roller 13 are inserted and secured in corresponding recesses 60 of two brackets 61, of the rear in the drawing.
- the brackets can be moved in their length to adjust the distance between the two rollers from each other. This is symbolically indicated by the adjusting screws 62.
- the upper roller may be stored such that their Axis is movable in the three dimensions.
- the two rollers can be reversed, ie the male roller below and driven and the die roller above. This reversal of the position of the rollers also corresponds to the representations of FIGS. 21-36 ,
