Description

The invention relates to a method for producing blanks for an inner envelope of a cigarette group, wherein the blanks are separated from a continuous material web, and wherein the material web is passed through an embossing device and provided with an embossing before separating the blanks, according to the preamble of the claim 1.

Furthermore, the invention relates to an apparatus for carrying out this method, according to the preamble of claim 10.

The invention can be used in connection with the production of blanks for inner liners of cigarette packs. These surround the cigarette group on all sides to form a cigarette block, which is then placed in the cigarette pack. When the cigarette pack is put into use for the first time, a tear-off flap is separated from the inner liner so that access to the cigarette group is free.

Also common is the application of imprints on the web for the innerliner. For example, the material web can be embossed throughout. Also known is the embossing of single or multiple markers, such as logos, labels and the like. For this purpose, the material web is passed through an embossing device with embossing rollers, which serve to attach the embossing (s). The circumference of the embossing rollers corresponds to the length of a blank, so that in one revolution of the embossing roll exactly a blank is processed.

The separation of blanks from the material web is usually carried out in accordance with existing on the material web or applied print marks or other markings.

A problem when embossing the material web or blanks to be separated therefrom is that the length of the material web is changed by the embossing, namely shortened or, in rare cases, increased. This can lead to the embossing not being placed correctly in relation to the separating cuts for separating the blanks from the material web, and thus the desired result is not achieved. However, it has been shown that the degree of shortening of the web or the blanks is not exactly predictable, since this depends on many factors, such as the material used, the degree of wear of the embossing rollers, the embossing depth, the machine speed, the environmental conditions (especially humidity) and other factors not known in part.

On this basis, the invention has the object to further develop methods and devices of the type mentioned, in particular to solve the above problems.

A method for achieving this object has the features of claim 1. Accordingly, it is provided that, for controlling the change in the length of the material web or a blank to be cut out of the same, at least one parameter influencing the embossing (during the processing of the material web) is varied in order to control the embossing.

In particular, the embossing pressure or the embossing depth and / or the extension of the embossing and / or the web tension of the material web in the region of an embossing device come into consideration as parameters influencing the embossing. The phrase "and / or" is to be understood as meaning that only a single one of the parameters may be varied or multiple parameters in any number and combination.

It can be particularly advantageous if the at least one parameter influencing the embossing is varied over the length of a blank to be separated out of the material web. Thus, individual regions of the material web can be provided with differently strong or deep embossments, in order to obtain the result of an inner liner of the desired length.

Preferably, the procedure is such that the at least one parameter influencing the embossing is varied in a region of the blank which is not visible to the consumer after being packaged in a cigarette packet, in particular outside a region of the blank which is visible when the cigarette packet is open.

Furthermore, the at least one parameter influencing the embossing can be varied in one or more sections of a blank to be separated out of the material web. For example, more than two sections may be provided with different embossments.

Furthermore, it may be provided that the length of the blank following the embossing device is checked on the basis of markings, in particular print marks or embossing marks, attached to the material web or the blank. If the length of the blanks does not match the desired length, the parameter can be changed by a controller to arrive at the desired destination.

According to a preferred embodiment it can be provided that the test of Length of the blank by scanning of print marks or embossing marks is carried out, which are arranged on the unembossed material web at predetermined intervals, in particular such that the distance between two successive print marks or embossed marks is detected by means of sensors. Preferably, two successive print marks or embossing marks are detected simultaneously by means of a single sensor.

Another special feature may be that, in addition to the at least one parameter influencing the embossing, further parameters are stored in the control, according to which the at least one parameter is varied. It is conceivable, for example, the deposit or specification of the type of material of the material web and / or the machine speed and / or the machine acceleration and / or the quality of the embossing and / or the web tension and / or the type of the embossing unit and / or the presence and the Type of further embossing elements and / or the degree of wear of the embossing rollers and / or the position of the embossing areas and / or the location of areas in which no variation of parameters is allowed.

An apparatus for solving the above-mentioned problem has the features of claim 10. It is therefore provided that, for controlling a change in the length of the material web or a blank to be separated out of the same, at least one parameter influencing the embossing can be varied by means of a control.

Further advantageous embodiments and features of the invention are to be taken from the dependent claims and the description of the rest.

Preferred embodiment will be described below with reference to the drawing. In this show:

6 a section through an embossing device along section line VI-VI in 5 .

7 an alternative embodiment of the embossing device in a representation according to 6 , and

8th a schematic representation of the control or the control process.

The invention will be explained below with reference to a cigarette pack 10 of the type hinge-lid. cigarette packs 10 of this type have a box part 11 , as well as a swiveling on the box part 11 stored lid 12 , By opening the lid 12 the consumer arrives at the package contents, namely the cigarette block 13 , At the cigarette block 13 it is a group of cigarettes, not shown, which are cut into a blank 14 is wrapped in thin packaging material (so-called inner liner). The cut 14 surrounds the cigarette group on all sides and serves as aroma protection.

The cigarette block 13 protrudes at the top of the box part 11 out and has a tear-off 15 passing through a perforation line from the rest of the blank 14 can be separated. The tear flap 15 becomes with first putting into use the cigarette pack 10 removed to give the consumer access to the cigarettes.

Continue to be part of the cigarette pack 10 is a collar 17 in the box part 11 is arranged and from the upper opening of the box part 11 protrudes. Indicated is a collar window 18 in the area of a collar front wall. In the area of this collar window 18 is the cut 14 or the tear-off flap 15 with a marker 19 which in the present case indicates that the tear-off flap 15 for putting the cigarette pack into use 10 to remove. The mark 19 may be appropriate for example by embossing or printing.

2 shows a spread blank 14 for the inner wrapping or as Innerliner. By different hatching are various embossed areas of the blank 14 indicated. Furthermore, longitudinal fold lines 20 and transverse fold lines 21 represented, which the individual areas or folding flaps of the blank 14 delimit each other.

The cut 14 is placed starting from a bottom of the cigarette group on the front and back and in the area of a Top of the cigarette group closed by a Kuvertfaltung. Side tabs of the blank 14 are superimposed in the range of narrow sides of the cigarette group, so that the cigarette group on all sides of the blank 14 is surrounded.

Furthermore, it can be seen that the hatched areas over the entire surface of the blank 14 extend. The cut 14 is thus continuous over the full length and width (full area) with an embossing 22 . 23 Mistake.

The imprints 22 . 23 be by means of an embossing device described in detail below 24 applied. The embossing device 24 has a pair of embossing rollers 25 . 26 , between which a continuous material web 27 for attaching the coinage is performed. After that, individual blanks 14 from the material web 27 separated out. This is done by means of a cutting device 28 that have a print mark 29 at the cutting 14 is controlled.

Both the embossing device 24 as well as the cutting device 28 are preferably coupled to the machine cycle.

In 2 is next to the unfolded blank 14 or parallel to the longitudinal extent of the embossing pressure 30 the embossing rollers 25 . 26 applied over the machine angle. Furthermore, some variants are shown with dashed lines. In detail:
The cut 14 has imprints 22 that with a certain embossed print 30 to be created. In the present case, these are areas of the blank 14 with the cigarette pack open 10 are visible, namely in the region of an upper side of the cigarette group, as well as a circumferential portion of the side surfaces of the cigarette group, as far as these from the box part 11 stick out and not through the collar 17 are covered. Specifically, these are sections of the blank 14 in the area of a front, the back and the two narrow sides of the cigarette group.

According to the winding of the blank 14 around the cigarette group are the imprints 22 each in the end of the blank 14 arranged. In between there is an imprint 23 , in the present case, with a lower embossing pressure 30 is generated and thus has a weaker expression. For this purpose, as shown in 2 the embossing print 30 starting from an initial pressure necessary for the creation of the imprints 22 is first reduced and held constant for a time at a lower level, and then later increased again to the initial pressure. The higher embossing pressure leads accordingly 30 to a greater shortening of the blank 14 and the lower embossing pressure 30 to a smaller shortening of the blank 14 ,

2 further shows that the more pronounced imprint 22 until shortly after the perforation line 16 the tearflap 15 extends. The embossing print 30 but already when passing through the area of the perforation line 16 gradually lowered. Accordingly, with the later increase of embossing 30 method. This is raised before the later visible area of the blank 14 is handled so as to ensure that the visible area of the blank 14 (completely) the desired embossing 22 having. The areas of the blank not visible to the consumer 14 get a less pronounced imprint 23 ,

The result is at least the area of the blank 14 , the one with the weaker imprint 23 is provided as a so-called control range 31 to disposal. If this rule area 31 the embossing device 24 passes through, the embossing can 30 be varied according to the respective requirements. This does not necessarily mean a reduction in the embossing pressure 30 be, as the dashed lines show. Furthermore, of course, the timing of the variation of the embossing pressure 30 be displaced, as by the two double arrows 33 indicated. As a result, this can be done by varying the embossing pressure 30 the length of the blank 14 be adjusted. The details of the control will be discussed in more detail below.

The mark 19 is in the embodiment according to 2 formed as printing, at predetermined intervals on the unembossed material web 27 is appropriate. By controlling the embossing pressure 30 and optionally further parameters, such as web tension, etc., the shortening of the material web 27 or the blank 14 be controlled so that the separating cut is carried out so that the mark 19 positionally correct on the blank 14 is positioned.

3 shows a further variant of an embossed blank 14 , Here is a strong imprint 22 in the area of the later top of the cigarette block 13 intended. This is followed by an area with a weaker character 23 at that, a little over the visible area 32 extends, namely in the direction of the underside of the cigarette block. By further lowering the embossing pressure 30 results in an even less embossed area or possibly a non-embossed area 34 around the longitudinal center of the blank 14 around. Then the embossing is done 30 increased again, leaving an area with a weak imprint 23 is formed, to which again by application a higher embossing pressure 30 an area with a stronger character 22 followed.

In addition to controlling the length of the blank 14 and the positioning of the mark 19 can by the variation of the embossing pressure 30 also optical effects can be achieved.

Furthermore, the blank has 14 unlike the embodiment according to 2 no print mark, but an embossed mark applied by embossing 67 , The embossed mark 67 is in the present case preferably together with the imprints 22 . 23 through the embossing device 24 on the material web 27 appropriate. It is also conceivable that the embossed mark 67 separate from the rest of the coins 22 . 23 is attached.

Furthermore, the mark 19 formed in this embodiment by embossing. The mark 19 can preferably by the embossing device 24 or by a separate unit. The embossed marking is completed 19 by a highlighting 68 at predetermined intervals on the unembossed material web 27 is appropriate.

Accordingly, the location of the mark 19 and highlighting 68 matched to each other and to the position of the separating cut. This is done by the already described control of one or more, the change in the length of the material web influencing parameters, such as preferably the embossing pressure 30 , Furthermore, the location of the embossed mark 67 and / or highlighting 68 be influenced by the fact that the position of the embossing rollers 25 . 26 is changed while the web 27 free through the embossing device 24 running. For the purpose of full disclosure, this will be to the DE 10 2005 056 627 A1 from the applicant's home.

It goes without saying that of course the marking 19 as in the first embodiment by printing and highlighting 68 can be formed by embossing. It is also conceivable that marking 19 and emphasis 68 both can be designed consistently by embossing or printing.

As a result, the two embodiments show that on the one hand, the depth of the embossing or the embossing pressure can be changed. On the other hand, it is shown that the size of the area of the blank to be embossed is also important 14 can be varied. Both can be used to "adjust" or control the pre-conditional change in length so that the blank 14 later exactly the intended length, or the mark 19 at the intended position on the blank 14 or in relation to the emphasis 68 located.

4 and 5 show a packing machine for Hinge-Lid-packages, as well as the arrangement of bobbins 35 with the material web 27 , Below the bobbins 35 there is a railway storage 36 , as well as the embossing device 24 , The material web 27 is from one of the two reels 35 deducted and over the Bahnspeicher 36 the embossing device 24 fed. There the web experiences 27 an embossing, being between the two embossing rollers 25 . 26 is passed. After that, the material web 27 in the area of the cutting device 28 guided and there in individual blanks 14 separated. Subsequently, the individual blanks 14 one after the other by one cigarette group each 13 wound.

6 shows a possible construction of the embossing device 24 , The embossing device 24 therefore has a housing 37 in which the two embossing rolls 25 . 26 are stored. A first embossing roll 25 is stationary rotatable about an axis 38 on the housing 37 stored. An axis 39 the second embossing roll 26 is displaceably mounted, namely transversely to the embossing plane or to the plane of the web 27 , In the present case, the axis 39 the second embossing roll 26 about disc springs 40 stored. The embossing is done by two pestles 41 generated by the cup springs 40 on the axis 39 the second embossing roll 26 Act. The pestles 41 are over a pressure bar 42 connected with each other. About a lever 43 can the pressure bar 42 and thus the pestle 41 be moved transversely to the embossing plane. To operate the lever 43 serves in the present case, a compressed air cylinder 44 ,

The compressed air cylinder 44 is via a signal line 45 controlled by a controller, not shown. The compressed air cylinder 44 are several compressed air storage 46 assigned via compressed air lines 47 with the compressed air cylinder 44 are connected. The compressed air storage 46 serve to provide the required pressure without delay and in sufficient quantity. Through the compressed air storage 46 "Storage Location" and "Consumption Location" are more or less merged.

In the present case are three compressed air storage 46 preferably provided with different pressure. The pressure in the respective compressed air reservoir 46 is via a corresponding compressed air regulator 48 controlled. Via corresponding compressed air lines 47 stand the compressed air storage 46 with the pressure regulators 48 and a compressed air source 49 in connection.

Also the compressed air regulator 48 can via signal lines 45 connected to the controller to the pressure in the compressed air storage 46 to regulate.

The compressed air cylinder 44 is a three-way valve 50 associated with, in accordance with the control of the air cylinder 44 with the pressure from one or more compressed air reservoirs 46 is charged. The three-way valve 50 is as close as possible to the air cylinder 44 arranged, thus long reaction times through long compressed air lines 47 can be avoided.

With the help of the compressed air cylinder 44 can either be through the cup springs 40 exerted pressure to be increased, or the air cylinder 44 is used to apply an opposite pressure and counteract the pressure of the disc springs.

It is understood that instead of a pneumatic control of the embossing pressure 30 also a hydraulic control is possible.

It is also conceivable to use servomotors for controlling the embossing pressure 30 , This is also on 7 directed. Instead of the air cylinder 44 Here is a (fixed) servomotor 51 provided, via a signal line 45 connected to the controller. By the servomotor 51 becomes a cam 52 powered by a cam follower 53 on the lever 43 is applied so that by appropriate rotation of the cam 52 the embossing print 30 can be controlled.

Another special feature is that the embossing device 24 is mounted interchangeably on the packaging machine. This is solved so that the control organs, such as the air cylinder 44 can remain on the machine. For identification of the embossing device used 24 carries each embossing device 24 a distinguishing feature, such as a transponder 54 , This works together with a reader located on the machine 55 , which is connected to the controller.

To control the embossing of the material web 24 are following the embossing device sensors 56 or a camera 57 provided with which the print marks 29 on the material web 24 be scanned so that information about the length of blanks to be separated 14 can be won. Furthermore, the sensors can 56 or the camera 57 used to monitor the quality of the embossing.

• – Ergebnisse der Überwachung der Qualität der Prägung,
• – Ergebnisse der Überwachung der Länge der Zuschnitte 14 anhand der abgetasteten Druckmarken 29,
• – Informationen über die Art der anzubringenden Prägung,
• – Informationen über das verwendete Material für die Materialbahn 27,
• – Informationen über die Maschinengeschwindigkeit mittels eines Encoders 59,
• – Informationen über die zum Einsatz kommende Prägeeinrichtung 24,
• – Informationen über die gegebenenfalls zum Einsatz kommende Rilleinrichtung 60, sofern zusätzlich zur Prägung auch noch Rillungen am Zuschnitt 14 bzw. der Materialbahn 27 angebracht werden.

In 8th they are in control 58 ongoing processes are shown schematically. The controller can capture a range of input data, such as:

• - results of monitoring the quality of the stamping,
• - Results of monitoring the length of the blanks 14 based on the sampled print marks 29 .
• - information on the type of embossing to be applied,
• - Information about the material used for the material web 27 .
• - Information about the machine speed by means of an encoder 59 .
• - Information about the embossing equipment used 24 .
• - Information about the optional groove used 60 , provided in addition to the embossing also grooves on the blank 14 or the material web 27 be attached.

Based on the information available controls the controller 58 on the one hand, the web tension, for example one on a printing cylinder 61 for influencing the web memory 36 , the embossing print 30 the creasing device 60 , as well as the embossing 30 the embossing device 24 , These are in the controller 58 corresponding cams 62 . 63 . 64 . 65 deposited.

In practice, the user selects the type of embossing to be produced and enters information for identifying the material used. Alternatively, the type of material can also be detected by sensors. The type of embossing device 24 as well as the groove device 60 can also via readout devices 55 be entered or entered manually by the operator. The machine speed is via the encoder 59 detected.

Based on the given boundary conditions, the controller selects 58 suitable cams 62 . 63 . 64 . 65 to control the individual units. These are preferably in a database 66 deposited, so that for each individual case corresponding cams 62 . 63 . 64 . 65 be available.

Furthermore, during operation of the packaging machine, the control cams 62 . 63 . 64 . 65 optionally also be adjusted, for example, the length of the blanks 14 adapt if, for example, the environmental conditions, in particular the humidity has changed or not in the control 58 deposited cams 62 . 63 . 64 . 65 fits. It is understood that not always all cams 62 . 63 . 64 . 65 must be adjusted, but possibly only one or more of the parameters or the cams 62 . 63 . 64 . 65 , for example, only the embossing 30 the embossing device 24 and / or the web tension.

According to a further embodiment of the invention, the embossing pressure or the embossing depth can be selected depending on the packaging material to be processed for the innerliner. It is conceivable, for example, that the operator or machine operator manually sets the embossing pressure in relation to the material. It is also conceivable that the stamping by the controller 58 adjusted according to the material. Furthermore, the embossing pressure may preferably be constant, in particular constant over the length of one or more blanks to be separated out of the material web 14 , The material-related embossing pressure or embossing strength can also be adjusted manually relative to the value predetermined by the material. This can be done either manually by the operator or automatically by corresponding scanning of print marks 29 as already described, in each case such that the length of a blank to be separated out of the material web 14 corresponds to a desired length.
