Description

The invention relates to a device and a printing unit for the alphanumeric identification of securities according to the preamble of claims 1 and 14 and a securities printing machine according to claim 15.

Through the WO 2007/148288 A2 a device and a method for the alphanumeric identification of printed products are known, individual numbering wheels being driven mechanically independently of one another by their own drive motors, in particular brushless DC motors. Each numbering wheel carrying a plurality of alphanumeric characters additionally carries a magnet on the outer circumference for the purpose of calibration. B. a Hall sensor can be detected. In addition, a locking element is provided, which is pressed from the inside by spring force into a groove in the inner circumference of the numbering wheel to secure the set position and is moved out of the groove by applying an electric current to a coil via reluctance forces.

In the JP 2004-160788 numbering wheels are driven by biaxial stepper motors, the angular positions being detected by magnets, which are located on the outer circumference of intermediate gear wheels of the respective drive train and are detected by magnetic sensors. A comb-like locking element engages between the teeth of gears connected to the numbering wheels. It is turned on by activating a solenoid and turned off by spring force when the solenoid is deactivated.

The WO 2016/000741 A1 discloses a device and a method for the alphanumeric identification of printed products, with individual numbering wheels being driven by stepper or brushless DC motors. The numbering wheel carries markings arranged on the outer circumference between the characters, in particular magnets, which are activated by sensors, e.g. B. Hall sensors are detectable. In addition, the motor has an encoder that can be used to monitor the movement of the motor axis.

The DE 38 41 231 A1 relates to a coding device for type or print wheels, in particular on franking machines. In one embodiment, a position of the type wheel is characterized by the signal level of a Hall sensor which is arranged in a fixed axis within the rotating type wheel. The inner circumference of the type wheel does not run with a constant radius, but in a spiral shape with a varying distance from the axis. In a further development, individual teeth with a tooth height that varies along a spiral line can be provided on the circumference, correlated to the types. When the type wheel is in operation and a certain type is set, the value present at the sensor output is compared with the setpoint value for the signal previously obtained through a referencing run. When the desired position is reached, the next type wheel is set or back to the main program.

In addition to the p marking tools 02 One or more such wheel-shaped or ring-shaped elements can also be provided which, although structurally, are the marking tools 02 match, but no characters Z _Z on the circumference and only serve to fill up empty spaces in the character string or to compensate for an undersize.

Such devices 01 for the alphanumeric labeling of printed products, in short labeling devices 01 or numbering devices 01 , can in principle be provided in any marking machine, but are preferably used here for marking up security copies in a printing unit 04 a printing machine, preferably a rotary printing machine, in particular a security printing machine. Such a device includes, for example, an input-side printing material supply through which the input side of the printing machine is to be printed Substrate B. , e.g. B. as a web or preferably arcuate printing material B. , can be fed, an output-side product receptacle, through which the at least simply printed substrate B. to containers, e.g. B. to rolls or preferably sheet stacks, can be combined, and a printing unit arranged between them in the printing material path 04 , especially numbering printer 04 , through which, for example, in rows and columns on the substrate B. intended security benefits can be marked with multi-digit character strings, ie “numbered”.

The printing unit includes 04 for example a printing unit cylinder 06 , e.g. B. numbering cylinder 06 , which in the area of its circumference has several rows one behind the other, each with several marking devices arranged next to one another 01 carries, as well as the printing material B. printing cylinder supporting the printing 07 . Just in case sheet-shaped printing material B. this printing unit cylinder is used 07 , e.g. B. impression cylinder 07 , for example at the same time the sheet transport and includes one or more holding devices on its circumference 08 , e.g. B.

By means of the marking devices 01 are each print images of multi-digit character strings in direct printing or, if necessary, indirectly via at least one further printing unit cylinder onto the printing material B. applicable. The marking devices 01 can structurally with their frames 03 in the printing unit cylinder 06 be integrated. However, they are preferably arranged detachably on the circumference of a cylinder body and, in a preferred development, can be variably positioned at least in the circumferential direction on the cylinder body.

In the following - basically independent of the above application in a numbering printer 04 and / or a security printing machine, but preferably in connection with such or such - preferred designs, developments and design variants for such a marking device 01 set out.

In a preferred embodiment there are several, in particular all of the p numbering wheels 02 mechanically independent of each other by means of a motor. In principle, numbering wheels that can be driven mechanically independently of one another can be used 02 suitable drive motors 12 any embodiment can be provided. In this preferred embodiment, the respective one is a numbering wheel 02 mechanically independent of other numbering wheels 02 around the axis 11 rotating drive motor 12 but as a stepper motor 12 educated. The stepper motor 12 is designed for example with two phases and / or has z. B. a number of internal motor steps of 15 to 25, preferably 20 steps per revolution. The stepper motor is used to ensure good positioning accuracy 12 with a holding torque (energized) of at least 1.2 mNm, preferably at least 1.5 mNm.

For example, a high degree of angular accuracy for the numbering wheel 02 and / or to achieve an increase in the torsional resistance, comprises the drive train between the motor rotor and the numbering wheel 02 preferably a single or multi-stage reduction gear with a resulting reduction ratio of at least 15 (rotor revolutions): 1 (numbering wheel revolution), in particular in the range from 15: 1 to 25: 1, for example from 20: 1.

The drive train can be designed in different suitable ways in order to be removed from the drive motor 12 on the assigned numbering wheel 02 abort and, for example, to realize the above-mentioned reduction. In an embodiment variant not shown here, the drive train comprises z. B. a the drive motor 12 gearbox directly assigned at the output, e.g. B. planetary gear, with pinion on the output side 14th . Between that on the drive motor 12 or if necessary pinion seated on the auxiliary gear 14th and one of the numbering wheel 02 associated gearwheel which rotates with it in a rotationally fixed manner about the same axis of rotation 21st , e.g. B. Drive wheel 21st , a transmission with one or more gear stages is provided. For example, a first gear stage is through the pinion 14th and one with that meshing gear 16 , e.g. B. intermediate gear 16 , provided, the latter in a second gear stage on a larger gear 17th , e.g. B. spur gear 17th , drives that on a common shaft 18th is rotatably arranged with a further gear 19th in a third gear stage on the larger drive wheel 21st drives.

The drive motors 12 can be flat on brackets 13 , e.g. B. Sockets 13 , be arranged on top, for example, to dissipate heat generated during operation via the contact.

; Z_X vorgesehenen Felder F_f . Bei letzterem ist z. B. zusätzlich eine Zuordnungsvorschrift V zwischen dem beispielsweise durch eine Nummerierungssteuerung 57 vorgegebenes alphanumerisches Zeichen Z_Z und dem betroffenen Feld F_f vorgehalten. Die Abfolge der Zeichen Z_Z bzw. mehrstelligen Zeichenfolgen für die mindestens eine Nummeriervorrichtung 01 wird beispielsweise durch eine übergeordnete Nummerierungssteuerung 57 z. B. über entsprechende Nummeriervorschriften generiert und vorgegeben.For controlling the drive motor 12 , especially stepper motor 12 , this or its internal motor control is in signal connection to data processing and / or storage means, not shown here, of a control device 22nd , in which an assignment rule V between the working positions of the alphanumeric characters Z _Z and step numbers of the stepper motor 12 is held up. The assignment rule V can be in tabular form or in a functional manner Related, in particular be stored. The drive motor is or is in operation 12 to move one by means of the numbering wheel 02 character to be printed Z _Z in a working position in which the character concerned is Z _Z is in the position intended for printing by the control device 22nd or a control routine implemented in this using the assigned assignment rule V controlled or controllable. For example, starting from a specific step position of the stepper motor 12 or the numbering wheel 02 and a number of steps known for this position i ; j (with i, j from {1, 2, ... i _G } one for the character to be set below Z _Z or field F _f based on the assignment rule V one for this character Z _Z or field F _f relevant number of steps i '; j '(with i', j 'from {1, 2, ... i _G }) and one determined by the stepper motor from the difference 12 number of steps to be covered Δi ; Δj determined, whereby an evaluation of the distance can also take place with regard to the direction in which the new number of steps i '; j 'can be reached most quickly. The drive motor 12 is then according to the number of steps determined - possibly taking into account the direction of rotation R. - controlled. As long as there is no renewed change of the character to be printed Z _Z or field to be set F _f is pending, the position of the stepper motor 12 - possibly with the application of a holding current - held. As soon as the character to be printed changes again Z _Z or the field to be moved in the working position F _f is pending, the process for setting the new numbering wheel rotation position is repeated (see e.g. 12 ). In the assignment rule V can use the step numbers i ; j the working positions of the alphanumeric characters Z _Z and possibly spaces and / or error characters

; Z _X be assigned directly yourself or the one on the numbering wheel 02 for the characters Z _Z ;

; Z _X provided fields F _f . The latter is z. B. an additional assignment rule V between, for example, by a numbering control 57 default alphanumeric character Z _Z and the affected field F _f held up. The sequence of characters Z _Z or multi-digit character strings for the at least one numbering device 01 is for example through a higher-level numbering control 57 z. B. generated and specified using appropriate numbering rules.

The assignment rule V can basically be determined using any sensor system in a reference run, by means of which the working positions of the characters to be set Z _Z or field F _f relevant signal can be determined and can be linked to an absolute or relative step of a certain number of steps that is present for this working position. For example, the total number of for one revolution of the numbering wheel 02 required motor steps i _G drive through, by at least one sensor 23 ; 23.1 ; 23.2 the sensor device to the working positions of the characters Z _Z or fields F _f associated sensor-specific brands M _{m, r} recorded when the brand was recorded M _m if necessary, the corresponding number of steps resulting after a further evaluation and / or scaling or normalization i ; j registered and considered to be a sign Z _Z or field F _f is stored accordingly. Basically, the brands M _m or their information content readable by the sensor system is the respective field F _f or characters Z _Z include clearly and absolutely identifying information. This would mean a direct association between the characters Z _Z or field F _f and the number of steps relevant to the work position i ; j provided. In the version shown here, which is less complex with regard to the characteristics of the brand system, the respective working position of the characters is next to the Z _Z or fields F _f representing brands M _m a reference brand M _{m, r} , short reference mark M _{m, r} , assigned, which by their relative position a certain unique position of the numbering wheel 02 identifies and thereby the relative position of the individual characters Z _Z or fields F _f specifies. The process of detecting marks M _m ; M _{m, r} and the assignment of a step number in; i _r takes place at least until the brands M _m of all characters Z _Z or fields F _f - possibly including reference mark M _{m, r} - have been passed through, but preferably for at least one full turn of the numbering wheel 02 .

; Z_X zugeordnet werden (siehe z. B. exemplarisch eine Signalzuordnung S' nach Auswertung des Signalverlaufs S(23); S(23.1); S(23.2) in 10) und die Grundlage einer tabellarische Zuordnungsvorschrift V oder Stützstellen einer rechnerischen Zuordnungsvorschrift V bilden. Je nachdem, ob der Referierungslauf in einer beliebigen Nummerierradlage begonnen wurde und ob für die weitere Verwendung eine an der Referenzmarke M_m,r mit einer Schrittzahl i = 1 beginnende Skala vorliegen soll, kann eine Verschiebung der die Schrittzahl i betreffende Achse hin zu einer skalierten Zuordnung zwischen den Marken M_m ; M_m,r und skalierten Schrittzahlen j erfolgen bzw. vorgesehen sein (siehe z. B. exemplarisch eine Signalzuordnung S'' nach zusätzlicher Skalierung der ursprünglichen Signalzuordnung S' in 10). Die Schrittzahl i_G wird dabei z. B. zu einer Schrittzahl i_X, während die vormalige Schrittzahl i = 1 zur Schrittzahl i_X+1 wird. Für den oben angedeuteten Fall einer absoluten Identifizierbarkeit der einzelnen Marken M_m an deren spezifischer Ausprägung können o. g. Schritte im Zusammenhang mit dem Bezug auf das Referenzsignal S_R entfallen. Stattdessen kann dann direkt eine Zuordnung zwischen den einzelnen Feldern F_f oder Zeichen Z_Z ;

; Z_X und den originalen oder skalierten Schrittzahlen i; j erfolgen.In the preferred version here (see e.g. the purely qualitative representation in 9 and 10 ) will change with one turn of the numbering wheel 02 resulting signal curve S (23) ; S (23.1) ; S (23.2) at the output of the at least one sensor 23 ; 23.1 ; 23.2 tapped. Depending on the characteristics of the brands M _m ; M _{m, r} for example, typical characteristics result for the brand crossings, e.g. B. Maxima or a minimum S _min , against the number of steps taken i of the drive motor 12 plotted signal curve S (23) ; S (23.1) ; S (23.2) when the sensor 23 ; 23.1 ; 23.2 just from a brand M _m ; M _{m, r} of the rotating numbering wheel 02 is happening. In the example shown here, these are minima S _min which can basically be determined without further ado. A precise determination of the location of the characteristics, e.g. B. Minima S _min , can for example be done arithmetically using suitable frequency filters and / or edge evaluations. The values determined for the minima S _min present step numbers i can now take into account the position of the reference signal identifiable on the basis of the signal shape and / or sequence S _R the individual fields F _f or characters Z _Z ;

; Z _X be assigned (see e.g. a signal assignment as an example S ' after evaluating the signal curve S (23) ; S (23.1) ; S (23.2) in 10 ) and the basis of a tabular assignment rule V or support points of a computational Assignment rule V form. Depending on whether the referencing run was started in any numbering wheel position and whether one at the reference mark for further use M _{m, r} with a number of steps i = 1 starting scale should be available, a shift in the number of steps i relevant axis towards a scaled assignment between the marks M _m ; M _{m, r} and scaled step numbers j take place or be provided (see e.g. an example of a signal assignment S ″ after additional scaling of the original signal assignment S ' in 10 ). The number of steps i _G is z. B. to a step number i _X , while the previous step number i = 1 becomes the number of steps i _{X + 1} . For the above-mentioned case of absolute identifiability of the individual brands M _m the above-mentioned steps in connection with the reference to the reference signal can be adapted to their specific characteristics S _R omitted. Instead, an assignment between the individual fields can be made directly F _f or characters Z _Z ;

; Z _X and the original or scaled step numbers i ; j respectively.

Regardless of whether with the uniqueness of the brands M _m or with a reference mark M _{m, r} , is proceeded, is therefore based on the brands M _m ; M _{m, r} , certain work positions and the associated number of steps i the assignment rule V created, which can be done, for example, in the form of a table or a functional context. Is the reference mark M _{m, r} after the referencing run, for example, not at step “1”, scaling can also take place in such a way that the reference position is at step number “1”.
