Description

Die Erfindung betrifft ein Verfahren zum Verarbeiten von Lentikularfolie in Bogendruckmaschinen, wobei die Lentikularfolie nebeneinander angeordnete Linsenstreifen aufweist, die quer zur Bogenlaufrichtung verlaufen und die Bogen aus Lentikularfolie in Bogenlaufrichtung sowie quer zur Bogenlaufrichtung ausgerichtet werden.The invention relates to a method for processing lenticular sheet in sheet-fed printing machines, wherein the lenticular sheet has juxtaposed lens strips which extend transversely to the sheet running direction and the sheets of lenticular sheet are aligned in the sheet running direction and transverse to the sheet running direction.

Ein solches Verfahren ist aus dem Dokument US 5 424 553 bekannt.Such a method is known from US Pat. No. 5,424,553.

Lentikularfolie, die auch als Linsenrasterfolie bezeichnet wird, ist eine klartransparente Folie, die auf der Vorderseite eine Vielzahl nebeneinander angeordneter Wölbungen aufweist. Die Wölbungen verlaufen parallel zueinander und wirken als optische Linsen. Diese Folien finden Verwendung bei der Herstellung von Lentikularprodukten, wie z. B. beim Realisieren von Bildfolgen oder dreidimensionalen Bildeindrücken. Dazu wird die Rückseite der Lentikularfolie mit einen Sujet bedruckt und anschließenden Deckweiß aufgetragen oder Karton kaschiert.Lenticular sheet, also referred to as a lenticular sheet, is a clear transparent sheet having a plurality of side-by-side cambers on the front side. The bulges are parallel to each other and act as optical lenses. These films are used in the manufacture of lenticular products, such as. B. in the realization of image sequences or three-dimensional image impressions. For this purpose, the back of the lenticular sheet is printed with a subject and then applied opaque white or cardboard laminated.

Um Bildfolgen oder dreidimensionale Bildeindrücke realisieren zu können, ist es erforderlich, unterschiedliche Bilder in streifenförmige Bildteile zu zerlegen und diese sequentiell zu einem einzigen Sujet zu vereinigen. Dabei ist jede Streifensequenz aller zu vereinigenden Bilder genau so breit wie ein Linsstreifen und muss exakt darunter gedruckt werden. Nur so entsteht, je nach dem gewählten Betrachtungswinkel, der gewünschte Bildeffekt, d. h. das Sichtbarwerden von Bildfolgen oder der dreidimensionale Bildeindruck. Werden die Streifensequenzen nicht exakt unter den Linsenstreifen gedruckt, ist das Produkt unbrauchbar.In order to be able to realize image sequences or three-dimensional image impressions, it is necessary to divide different images into stripe-shaped image parts and to combine these sequentially into a single subject. Each stripe sequence of all images to be merged is exactly as wide as a line stripe and must be printed just below. Only then, depending on the selected viewing angle, the desired image effect, d. H. the visualization of image sequences or the three-dimensional image impression. If the strip sequences are not printed exactly under the lens strips, the product is unusable.

In bogenverarbeitenden Maschinen ist es allgemein üblich , die zur Verarbeitung gelangenden Bogen nach der Vorderkante auszurichten, indem diese mit der Vorderkante gegen Anlegmarken geführt werden. Nachfolgend wird der nach der Vorderkante ausgerichtete Bogen nach der Seitenkante ausgerichtet. Dazu wird der Bogen quer zur Bogenlaufrichtung verschoben und mit der Seitenkante gegen einen Seitenanschlag transportiert (DE 100 48 314).In sheet-fed machines, it is common practice to align the sheets to be processed with the leading edge by guiding them with the leading edge against picking marks. Subsequently, the aligned after the leading edge sheet is aligned to the side edge. For this purpose, the sheet is moved transversely to the direction of sheet travel and transported with the side edge against a side stop (DE 100 48 314).

Aus der DE 102 05 630 A1 ist es weiterhin bekannt, nach dem Ausrichten in Bogenlaufrichtung die Ist-Lage der Seitenkante durch Messmittel zu erfassen und einen Soll-Ist-Wert-Vergleich durchzuführen. Weicht der Ist-Wert vom Soll-Wert ab, wird ein Stellsignal generiert und einem Stellglied zugeführt. Das Stellglied steht mit einem in einem Anlegzylinder in axialer Richtung verschiebbar gelagerten Greifsystem in Verbindung. Durch Verschieben des Greifersystems wird dann die Soll-Lage der Seitenkante realisiert.From DE 102 05 630 A1, it is also known to detect the actual position of the side edge by measuring means after alignment in the sheet running direction and to perform a desired-actual-value comparison. If the actual value deviates from the desired value, an actuating signal is generated and fed to an actuator. The actuator is connected to a slidably mounted in a Anlegzylinder in the axial direction gripping system in combination. By moving the gripper system, the desired position of the side edge is then realized.

Gelangen die Bogen aus Lentikularfolie so zur Verarbeitung, dass die Linsenstrukturen quer zur Bogenlaufrichtung und damit parallele zur Bogenvorderkante verlaufen, werden diese nach der Vorderkante an die Vordermarken sowie nachfolgend nach der Seitenkante ausgerichtet und anschließend im Greiferschluss durch die bogenverarbeitende Maschine transportiert. Da die Vorderkante der Bogen aus Lentikularfolie nicht zwangsläufig immer genau zur Linsenstruktur der Lentikularfolie verläuft, sind qualitativ schlechte oder unbrauchbare Produkte nicht auszuschließen. Außerdem ist es erforderlich, durch manuelle Stellhandlungen die Streifensequenzen exakt den Linsenstreifen zuzuordnen, wodurch ebenfalls die Produktivität der Gesamtmaschine nachteilig beeinflusst wird.The sheets of lenticular sheet for processing so that the lens structures are transverse to the sheet running direction and thus parallel to the sheet leading edge, are this aligned with the leading edge after the front edge and subsequently to the side edge and then transported in the gripper closure by the sheet-processing machine. Since the leading edge of the sheets of lenticular film is not necessarily always exactly to the lens structure of the lenticular film, poor quality or unusable products can not be excluded. In addition, it is necessary to assign the stripe sequences exactly to the lens strips by manual manipulations, which also adversely affects the productivity of the overall machine.

Aufgabe der Erfindung ist es, ein Verfahren zu entwickeln, durch das sichergestellt wird, dass die Streifensequenzen exakt den parallel zur Vorderkante verlaufenden Linsenstreifen der Lentikularfolie zugeordnet werden.The object of the invention is to develop a method by which it is ensured that the strip sequences are assigned exactly to the lens strips of the lenticular sheet running parallel to the leading edge.

Erfindungsgemäß wird die Aufgabe durch ein Verfahren nach den Merkmalen des Anspruchs 1 gelöst.According to the invention the object is achieved by a method according to the features of claim 1.

Durch das erfindungsgemäße Verfahren ist es möglich, Bogen aus Lentikularfolie einer Bogendruckmaschine standgerecht, unabhängig von der Lage der Bogenvorderkante zur Linsenstruktur, zugeführen. Damit kann die Produktivität der Gesamtanlage und die Qualität der Lentikularprodukte erhöht werden.By means of the method according to the invention, it is possible to supply sheets of lenticular sheet to a sheet-fed printing press in a standardized manner, independently of the position of the sheet leading edge to the lens structure. Thus, the productivity of the entire system and the quality of the lenticular products can be increased.

In Fig. 2 it is shown that the front edge 3 is not identical to a contact line 7.

In Fig. 3 ist eine Bogenanlage mit einem Anlegtisch 12, einer Bogenbeschleunigungseinrichtung 14, die als Schwinganlage 15 ausgebildet ist, und einer Trommel 17 dargestellt. Am Anlegtisch 12 sind in einer Arbeitsposition befindliche Anlegmarken 13 gezeigt, die aus ihrer Arbeitsposition in eine unter dem Anlegtisch 12 gelegene Rastposition gebracht werden können. Die Schwinganlage 15 ist mit einem Bogenhaltesystem 16 ausgestattet und die Trommel 17 mit einem Greifersystem 18 versehen. Der Trommel 17 schließen sich Druckwerke 19 an, wobei der Trommel 17 unmittelbar ein erstes Druckwerk 19.1 nachgeordnet ist, dem sich weitere Druckwerke 19 anschließen können. In Fig. 3 ist noch eine n-tes Druckwerk 19.n dargestellt. Das erste Druckwerk 19.1 besteht aus einem ersten Druckzylinder 20.1, dem ein erster Offsetzylinder 21.1 zugeordnet ist, der mit einem ersten Plattenzylinder 22.1 in Wirkverbindung steht. Entsprechend weist das n-te Druckwerk 19.n einen n-ten Druckzylinder 20.n mit einem n-ten Offsetzylinder 21.n und einem n-ten Plattenzylinder 22.n auf. Die Druckwerke 19 sind durch Überführungstrommeln 23 verbunden. Dem ersten Plattenzylinder 22.1 ist eine erste Umfangsregister-Steuereinrichtung 24.1 und dem n-ten Plattenzylinder 22.n eine n-te Umfangsregister-Steuereinrichtung 24.n zugeordnet. Die Umfangsregister-Steuereinrichtung 24.1 bis 24.n können als an sich bekannte Vorrichtungen ausgebildet sein, die unabhängig voneinander betätigbar sind. Die Umfangsregister-Steuereinrichtungen 24.1 bis 24. n könne auch so konzipiert sein, dass mindestens den Plattenzylindern 22.1 bis 22.n jeweils ein Einzelantrieb zugeordnet ist. Die Einzelantrieb können dann derart beeinflusst werden, dass diese vor- oder nacheilend umlaufen, wodurch das Umfangsregister verändert wird.In Fig. 3, a sheet system with a feed table 12, a sheet accelerator 14, which is designed as a vibration system 15, and a drum 17 is shown. At the feed table 12 located in a working position Anlegmarken 13 are shown, which can be brought from its working position in a location below the feed table 12 locking position.

Correspondingly, the nth printing unit 19.n has an nth printing cylinder 20.n with an nth offset cylinder 21.n and an nth plate cylinder 22.n. The printing units 19 are connected by transfer drums 23. The first plate cylinder 22.1 is associated with a first circumferential register control device 24.1 and the nth plate cylinder 22.n with an nth peripheral register control device 24.n. The circumferential register control means 24.1 to 24.n may be formed as per se known devices which are independently operable. The circumferential register control devices 24.1 to 24 n can also be designed so that at least the plate cylinders 22.1 to 22.n each have a single drive is assigned. The individual drive can then be influenced in such a way that they circulate before or after, whereby the circumferential register is changed.

Auf dem Anlegtisch 12 sind ein von dem Greifersystem 18 gehaltener und ein mit der Vorderkante 3 an den Anlegmarken 13 anliegender Bogen 1 dargestellt. Der Anlegtisch 12 weist quer zur Bogenlaufrichtung 5 angeordnete Kanäle 25 auf, in denen Seitenziehmarken 26 gelagert sind, die einen Seitenanschlag 27 aufweisen (Fig. 4). In Bogenlaufrichtung 5 erstreckt sich im Anlegtisch 12 eine Messeinheit 28. Die Messeinheit 28 ist so im Anlegtisch 12 vorgesehen, dass der Vorderkantenbereich der an den Anlegmarken 13 anliegenden Bogen 1 erfasst werden kann. Dazu ist die Messeinheit 28 im Ausführungsbeispiel als optoelektronische Messeinheit ausgebildet. Es kann aber auch jedes andere Messprinzip verwendet werden.On the feed table 12 a held by the gripper system 18 and a with the front edge 3 to the Anlegmarken 13 fitting sheet 1 are shown. The feed table 12 has transversely to the sheet running direction 5 arranged channels 25 in which side pull marks 26 are mounted, which have a side stop 27 (Fig. 4). In the sheet running direction 5 extends in the feed table 12, a measuring unit 28. The measuring unit 28 is provided in the feed table 12, that the leading edge region of the voltage applied to the Anlegmarken 13 sheet 1 can be detected. For this purpose, the measuring unit 28 is formed in the embodiment as an optoelectronic measuring unit. However, any other measuring principle can also be used.

Die Messeinheit 28 ist in einer sich in Bogenlaufrichtung 5 im Anlegtisch 12 erstreckenden Aussparung angeordnet. Die Aussparung ist mit einen durchsichtigen Abdeckstreifen 29 verschlossen, so dass die Oberfläche des Anlegtischs 12 und des Abdeckstreifens 29 eine gemeinsame Ebene bilden. Die Messeinheit 28 ist mit einer Auswert- und Steuereinrichtung 30 verbunden, in der Soll-Werte eingegeben und dort gespeichert werden können. Die Auswert- und Steuereinrichtung 30 steht mit den Umlaufregister-Steuereinrichtungen 24.1 bis 24.n und mit einer Maschinensteuerung 31 in Verbindung.The measuring unit 28 is arranged in a direction extending in sheet running direction 5 in the feed table 12 recess. The recess is closed with a transparent cover strip 29, so that the surface of the feed table 12 and the cover strip 29 form a common plane. The measuring unit 28 is connected to an evaluation and control device 30, can be entered in the target values and stored there. The evaluation and control device 30 communicates with the circulation register control devices 24.1 to 24.n and with a machine control 31 in connection.

Die aus Lentikularfolie bestehenden Bogen 1 werden von einem nicht dargestellten Bändertisch auf den Anlegtisch 12 und mit der Vorderkante 3 gegen die in Arbeitsposition am Anlegtisch 12 positionierten Anlegmarken 13 transportiert und damit nach der Vorderkante 3 ausgerichtet. Der zur Ruhe gebrachte Bogen 1 wird von der Seitenziehmarke 26 erfasst, gegen den Seitenanschlag 27 geführt und nach der Seitenkante 4 ausgerichtet. Von dem ausgerichteten Bogen 1 wird durch die Messeinheit 28 die Vorderkantenlage erfasst. Dabei werden von der Messeinheit 28 jeweils die Lage der Vorderkante 3 und die Lage der daneben liegenden Berührungslinien 7 charakterisierenden Signale generiert und der Auswert- und Steuereinrichtung 30 zugeführt. In der Auswert- und Steuereinrichtung 30 wird das durch die Vorderkante 3 in der Messeinheit 28 generierte Signal ausgeblendet. Außerdem werden alle die Signale, die durch die parallel zur Vorderkante 3 verlaufenden Berührungslinien 7 in der Messeinheit 28 generiert werden, ausgefiltert, lediglich ein durch eine Berührungslinie 7 generiertes Signal wird nicht ausgeblendet und zu einem Soll-Ist-Vergleich in der Auswert- und Steuereinrichtung 30 herangezogen. In vorteilhafter Weise wird immer dazu das Signal verwendet, welches durch die Berührungslinie 7 generiert wird, die der Vorderkante 3 des Bogens 1 benachbart ist, wobei jedes andere Signal, welches durch eine Berührungslinie 7 generiert wurde, ebenfalls Verwendung finden kann. Der ausgerichtete und bezüglich seiner Vorderkantenlage erfasste Bogen 1 wird von dem Bogenhaltesystem 16 der Schwinganlage 15 übernommen, die Anlegmarken 13 werden aus ihrer Arbeitsposition in die Rastposition verbracht und der Bogen 1 zur Trommel 17 transportiert sowie durch diese an den ersten Druckzylinder 20.1 übergeben. Wurde in der Auswert- und Steuereinrichtung 30 beim Soll-Ist-Vergleich eine Abweichung von der Soll-Lage registriert, wird ein Stellwert realisiert, der einen Korrekturwert entspricht, um welchen durch die Umfangsregister-Steuereinrichtung 24.1 bis 24.n die Plattenzylinder 21.1 bis 21.n verstellt werden müssen, um eine exakte Zuordnung, ausgehend von der alsThe lenticular sheet consisting of sheets 1 are transported by a belt table, not shown on the feed table 12 and with the front edge 3 against the position in the working position at the feed table 12 positioning marks 13 and thus aligned with the front edge 3. The retired sheet 1 is detected by the side puller 26, guided against the side stop 27 and aligned with the side edge 4. From the aligned sheet 1 is detected by the measuring unit 28, the leading edge position. In this case, the position of the leading edge 3 and the position of the adjacent lines of contact 7 are generated by the measuring unit 28 and signals are fed to the evaluation and control device 30. In the evaluation and control device 30, the signal generated by the front edge 3 in the measuring unit 28 is blanked out. In addition, all the signals that are generated by the parallel to the leading edge 3 extending lines of contact 7 in the measuring unit 28, filtered out, only a signal generated by a contact line 7 signal is not hidden and a target-actual comparison in the evaluation and control device 30 used. Advantageously, the signal generated by the contact line 7 which is adjacent to the front edge 3 of the sheet 1 is always used, whereby any other signal generated by a contact line 7 can also be used. The aligned and detected with respect to its leading edge position sheet 1 is taken over by the sheet holding system 16 of the oscillating system 15, the Anlegmarken 13 are moved from their working position to the rest position and the sheet 1 transported to the drum 17 and passed through this to the first impression cylinder 20.1. Was in the evaluation and control device 30 in the target-actual comparison, a deviation from the target position registered, a control value is realized, which corresponds to a correction value to which by the circumferential register control device 24.1 to 24.n the plate cylinder 21.1 to 21 .n must be adjusted to an exact assignment, starting from as

Soll-Wert festgelegte Berührungslinie 7, der einzelnen Streifensequenzen 11 zu den Linsenstreifen 6 zu erreichen. Da der Stell-/Korrekturwert der von einem auf dem Anlegtisch 12 befindlichen Bogen 1 ermittelt wurde, beim Transport durch jedes der Druckwerke 19.1 bis 19.n berücksichtig werden muss, werden die einzelnen Umfangsregister-Steuereinrichtungen 24.1 bis 24.n synchron zum Durchlauf eines ausgemessenen Bogens 1 mit dem jeweils zugehörigen Stell-/Korrekturwert angesteuert. Das wird durch die Auswert- und Steuereinrichtung 30 unter Berücksichtigung der durch die Maschinensteuerung 31 umgesetzten Maschinendrehzahl oder Druckgeschwindigkeit realisiert. Grundsätzlich ist es möglich, die bezüglich ihrer Vorderkantenlage erfassten Bogen 1 aus Lentikularfolie nach einer der Berührungslinien 7 auszurichten, indem das Bogenhaltesystem 16 der Bogenbeschleunigungseinrichtung 14 oder das Greifersystem 18 der Trommel 17, beeinflusst durch die Auswert- und Steuereinrichtung 30, über zusätzliche Stelleinrichtungen vor- oder nacheilend angetrieben werden.Target value fixed touch line 7, the individual stripe sequences 11 to reach the lens strips 6. Since the setting / correction value of the sheet 1 located on the feed table 12 has been determined, must be taken into account during transport through each of the printing units 19.1 to 19.n, the individual circumferential register control means 24.1 to 24.n are synchronized with the passage of a measured Sheet 1 with the respective associated setting / correction value driven. This is realized by the evaluation and control device 30, taking into account the machine speed or printing speed converted by the machine control 31. In principle, it is possible to align the sheets 1 of lenticular foil, which have been grasped with respect to their leading edge position, to one of the contact lines 7, by the sheet-holding system 16 of the sheet acceleration device 14 or the gripper system 18 of the drum 17, influenced by the evaluation and control device 30, are driven forward or backward via additional adjusting devices.

Claims (9)

  1. Method of processing lenticular films in sheet printing machines, wherein the lenticular films have lens strips which are arranged adjacent to one another and extend transversely to the sheet running direction, and the sheets of lenticular films are oriented both in sheet running direction and transversely to the sheet running direction, characterised in that for determination of the actual position of a sheet (1) oriented with respect to a front edge (3) the position of a respective contact line (7), which is formed between two adjacent lens strips (6), is detected and compared in an evaluating and control device (30) with a target position and in the case of an actual position deviating from the target position there is generated a setting value for realisation of a leading or trailing movement, which makes possible the target position, of plate cylinders (22.1 - 22.n), of a gripper system (18) mounted in a drum (17) or of a sheet folding system (16) of a sheet accelerating device (14).
  2. Method according to claim 1, characterised in that a circumference register control device (24.1 - 24.n) is associated with each plate cylinder (22.1 - 22.n) and is controlled synchronously with the transit of the sheet (1) by the respectively associated setting values of the evaluating and control device (30).
  3. Method according to claim 1, characterised in that a setting unit to which the setting values are fed is associated with the gripper system (18).
  4. Method according to claim 1, characterised in that a setting unit to which the setting values are fed is associated with the sheet holding system (16).
  5. Method according to claim 1, characterised in that for detection of a front edge region of the sheet (1), which is aligned with respect to the front edge (3), there is provided a measuring unit (28) by which signals characterising the position of the front edge (3) and the position of the contact lines (7) are generated and are fed to the evaluating and control device (30).
  6. Method according to claim 5, characterised in that in the evaluating and control device (30) the signals characterising the position of the front edge (3) and the position of the contact lines (7) are filtered out to a signal characterising a predeterminable contact line (7).
  7. Method according to claim 6, characterised in that the signal characterising the position of the predeterminable contact line (7) is based on a target/actual value comparison.
  8. Method according to claim 6, characterised in that as predeterminable contact line (7) there is selected the contact line (7) directly adjacent to the front edge (3).
  9. Method according to claim 1, characterised in that the evaluating and control unit (30) is connected with a machine control (31) for taking over control magnitudes characterising the machine rotational speed or the printing speed.
