Description

Die Erfindung betrifft eine Einrichtung zum Erfassen der Lage einer Kante eines durchsichtigen Verarbeitungsgutes, das einer Druckmaschine zugeführt wird, mit einer optoelektrischen Messeinrichtung, die mindestens aus einer Reflexzeile besteht, welcher als kontrastunterstützendes Mittel eine Reflexfolie oder Reflexschicht zugeordnet ist.The invention relates to a device for detecting the position of an edge of a transparent Processing goods that are fed to a printing press with an optoelectric Measuring device that consists of at least one reflex line, which serves as a contrast-enhancing Means a reflective film or reflective layer is assigned.

Um den in Druckmaschinen zur Verarbeitung gelangenden Bedruckstoff lagegenau zuführen zu können, ist es erforderlich, seine Istlage zu erfassen und nachfolgend einer Solllage anzugleichen. Der Bedruckstoff kann dabei bahn- oder bogenförmig vorliegen, wobei dieser aus unterschiedlichen Materialien, wie z.B. Papier, Karton, Blech oder einem durchsichtigen Verarbeitungsgut bestehen kann.In order to precisely feed the printing material to be processed in printing machines To be able to, it is necessary to record its actual position and then adjust it to a target position. The printing material can be in the form of a web or sheet, and this made of different materials, e.g. Paper, cardboard, sheet metal or a clear Processing goods can exist.

Aus der DE 101 36 871 A1 ist es bekannt, eine optoelektrische Messeinrichtung als Reflexzeile auszubilden und mit dieser die Istlage eines band- oder bogenförmigen Verarbeitungsgutes zu erfassen. Die Reflexzeile ist in einem Abstand über dem zu erfassenden Verarbeitungsgut angeordnet. Auf der Reflexzeile bildet sich die zu detektierende Kante als Hell-/Dunkelsprung ab, durch den ein Signal generiert wird, welches zur Bestimmung der Istlage der Kante einer Verarbeitungselektrik zugeführt wird. Um unabhängig vom zur Verarbeitung gelangenden Material einen exakt konturierten Hell-/Dunkelsprung realisieren zu können, ist der Reflexzeile ein kontrastunterstützendes Mittel zugeordnet. Dieses kontrastunterstützende Mittel ist z.B. im Anlegtisch vorgesehen und senkrecht dazu die Reflexzeile angeordnet.From DE 101 36 871 A1 it is known to use an optoelectric measuring device as a reflex line train and with this the actual position of a ribbon or sheet-shaped processing goods capture. The reflex line is at a distance above the material to be processed arranged. The edge to be detected forms a light / dark jump on the reflex line from which a signal is generated which is used to determine the actual position the edge of a processing electronics is supplied. To regardless of processing material can achieve a precisely contoured light / dark jump a contrast-enhancing agent is assigned to the reflex line. This contrast-enhancing Mean is e.g. provided in the feed table and the reflex line arranged perpendicular to it.

Nachteilig ist, dass bei der Verarbeitung eines durchsichtigen, farblosen Materials, wie z.B. Klarsichtfolien, sich eine Kante nicht mit einem solchen konturierten Hell-/Dunkelsprung auf der Reflexzeile abbildet, dass von dieser ein die exakte Lage der Kante wiedergebendes Signal generiert und der Verarbeitungselektrik zugeführt werden kann.It is disadvantageous that when processing a transparent, colorless material such as e.g. Clear films, an edge not with such a contoured light / dark jump of the reflex line shows that this reflects the exact position of the edge Signal generated and can be fed to the processing electronics.

Aufgabe der Erfindung ist es, eine bekannte Einrichtung mit einfachen Mitteln so zu verändern, dass auch die Lage der Kante eines durchsichtigen Verarbeitungsgutes sicher erfasst werden kann.The object of the invention is to change a known device with simple means so that the position of the edge of a transparent material to be processed is reliably detected can be.

Erfindungsgemäß wird die Aufgabe durch eine Einrichtung nach den Merkmalen des Anspruchs 1 gelöst. According to the invention the object is achieved by a device according to the features of the claim 1 solved.

Durch die erfindungsgemäße Lösung ist es möglich, mit einfachen Mitteln sicher zu stellen, dass auch bei der Verarbeitung von durchsichtigem Verarbeitungsgut die zu erfassende Kante so konturiert auf einem Empfänger abgebildet wird, dass ein die exakte Lage der Kante wiedergebendes Signal generiert werden kann.The solution according to the invention makes it possible to ensure with simple means that that even when processing transparent processing goods, the data to be recorded Edge is contoured on a receiver so that the exact position of the edge reproducing signal can be generated.

An einem Ausführungsbeispiel wird die Erfindung näher erläutert.The invention is explained in more detail using an exemplary embodiment.

In Fig. 1 ist ein Anlegtisch 1 mit Verarbeitungsgut 2, das als Bogen 3 ausgebildet ist, dargestellt. Die Bogen 3 werden in Förderrichtung 4 auf den Anlegtisch 1 und mit der Vorderkante gegen Vordermarken 5 transportiert. Zum Erfassen der Lage einer Kante 6 ist eine sich über mindestens einen für die jeweilige Druckmaschine charakteristischen Formatdifferenzbereich 7 erstreckende Traverse 8 vorgesehen. Der Formatdifferenzbereich 7 wird gebildet aus der Differenz zwischen dem maximalen und dem minimalen Format der zur Verarbeitung gelangenden Bogen 3, so dass sich beidseitig der Bogen 3 jeweils ein Formatdifferenzbereich 7 ergibt. Es wird jedoch nur anhand des in Förderrichtung 4 auf der linken Seite gelegenen Formatdifferenzbereichs 7 die Einrichtung beschrieben.
Die Traverse 8 ist gestellfest angeordnet. An der Traverse 8 ist verschiebbar ein Gehäuse 9 mit einer Reflexzeile 10 vorgesehen. Die Reflexzeile 10 besteht in bekannter Weise aus einer Beleuchtungseinrichtung, die z.B. als LED-Zeile ausgebildet ist und einer CCD-Zeile, die aus einer Vielzahl von in einer Reihe nebeneinander angeordneten Messelementen besteht. Durch die Beleuchtungseinrichtung der Reflexzeile 10 werden Lichtstrahlen 13 emittiert, die unter einem Neigungswinkel α zur Oberfläche des Anlegtischs 1 und damit auch zur Oberfläche des jeweils auszurichtenden Bogens 3 verlaufen. In dem Bereich, in dem die Lichtstrahlen 13 der Reflexzeile 10 auf den Anlegtisch 1 auftreffen, ist ein Einsatzstück 11 im Anlegtisch 1 so auswechselbar gelagert, dass die Oberfläche des Einsatzstücks 11 mit der Oberfläche des Anlegtischs 1 eine Ebene bildet. Die Oberfläche des Einsatzstücks 11 ist mit einer Reflexionsschicht oder mit einer Reflexionsfolie versehen. Die Reflexionsschicht oder die Reflexionsfolie hat die Eigenschaft, einfallendes Licht diffus zu reflektieren bzw. abweichend von einer regulären Reflexion das Licht bei einem schrägen Einfall zur Lichtquelle zurückzusenden.
Wie in Fig. 4 gezeigt, treffen die von der Reflexzeile 10 emittierten Lichtstrahlen 13 unter dem Neigungswinkel α sowohl auf die Oberfläche des aus einem durchsichtigen Material bestehenden Bogens 3 als auch außerhalb des Bogens 3 auf die Reflexionsschicht oder Reflexionsfolie des Einsatzstücks 11 auf. Die auf der Oberfläche des durchsichtigen Bogens 3 auftreffenden Strahlen werden regulär nach dem Reflexionsgesetz reflektiert, während die auf die Reflexionsschicht oder die Reflexionsfolie auftretenden Lichtstrahlen 13 zur Reflexzeile 10 zurückgeführt werden. Dadurch bildet sich die Kante 6 auf der Reflexzeile 10 als Hell-/Dunkelsprung ab, durch den ein die Istlage der Kante 6 wiedergebendes Signal generiert wird. Dieses Istsignal wird einer nicht dargestellten Verarbeitungselektrik zugeführt, in der ein die Solllage des Bogens 3 charakterisierendes Sollsignal abgelegt ist. In der Verarbeitungselektronik wird das Sollsignal mit dem Istsignal verglichen und bei einer Abweichung ein Stellsignal generiert. Das Stellsignal wird Stellelementen zugeführt, durch welche die Kante 6 des Bogens 3 aus der Istlage in die Solllage verbracht wird. Der Neigungswinkel α kann sich in einem Bereich 90° < α > 5° bewegen. Es ist deshalb möglich, die Traverse 8 und oder das Gehäuse 9 so verstellbar auszuführen, dass der Neigungswinkel α einstellbar ausgeführt ist.
In den Figuren 1 bis 4 sind die Reflexzeile 10 und die zugehörige Reflexionsschicht oder Reflexionsfolie oberhalb bzw. auf dem Anlegtisch 1 vorgesehen. Es ist auch möglich, die Reflexzeile 10 unterhalb des Anlegtischs 1 so anzuordnen, dass die Lichtstahlen 13 unter dem Neigungswinkel α emittiert werden und durch eine im Anlegtisch 1 vorgesehene, mit einer durchsichtigen Abdeckung verschlossene Aussparung treten. Dem Verlauf der Lichtstrahlen 13 angepasst, ist oberhalb des Anlegtischs 1 die Reflexschicht oder Reflexfolie z.B. an einer Traverse 8 angeordnet, so dass ebenfalls die auf die Reflexionsschicht oder Reflexionsfolie treffenden Strahlen abweichend von der regulären Reflexion zur Reflexzeile zurückgesandt werden und so auf dieser die Lage der Kante 6 abgebildet wird. In Fig. 1, a feed table 1 with processing goods 2, which is designed as a sheet 3, is shown. The sheets 3 are transported in the conveying direction 4 on the feed table 1 and with the front edge against front marks 5. To detect the position of an edge 6, a traverse 8 is provided which extends over at least one format difference area 7 which is characteristic of the respective printing press. The format difference area 7 is formed from the difference between the maximum and the minimum format of the sheets 3 to be processed, so that the sheet 3 each has a format difference area 7 on both sides. However, the device is only described on the basis of the format difference area 7 on the left in the conveying direction 4.
The traverse 8 is arranged fixed to the frame. A housing 9 with a reflex line 10 is slidably provided on the traverse 8. The reflex line 10 consists in a known manner of an illumination device, which is designed, for example, as an LED line and a CCD line, which consists of a plurality of measuring elements arranged in a row next to one another. Light rays 13 are emitted by the illumination device of the reflex line 10 and extend at an angle of inclination α to the surface of the feed table 1 and thus also to the surface of the sheet 3 to be aligned. In the area in which the light rays 13 of the reflex line 10 strike the feed table 1, an insert 11 is interchangeably mounted in the feed table 1 such that the surface of the insert 11 forms a plane with the surface of the feed table 1. The surface of the insert 11 is provided with a reflective layer or with a reflective film. The reflective layer or the reflective film has the property of diffusely reflecting incident light or, in contrast to a regular reflection, sending the light back to the light source in the event of an oblique incidence.
As shown in FIG. 4, the light beams 13 emitted by the reflex line 10 strike the surface of the sheet 3 made of a transparent material as well as the outside of the sheet 3 and the reflection layer or foil of the insert 11 at the angle of inclination α. The rays impinging on the surface of the transparent sheet 3 are regularly reflected according to the law of reflection, while the light rays 13 appearing on the reflective layer or the reflective film are returned to the reflective line 10. As a result, the edge 6 forms on the reflex line 10 as a light / dark jump, by means of which a signal which reflects the actual position of the edge 6 is generated. This actual signal is fed to processing electronics, not shown, in which a desired signal characterizing the desired position of the sheet 3 is stored. The setpoint signal is compared with the actual signal in the processing electronics and an actuating signal is generated in the event of a deviation. The control signal is fed to control elements by means of which the edge 6 of the sheet 3 is brought from the actual position into the desired position. The angle of inclination α can move in a range of 90 ° <α> 5 °. It is therefore possible to make the cross member 8 and or the housing 9 adjustable so that the angle of inclination α is adjustable.
In FIGS. 1 to 4, the reflex line 10 and the associated reflection layer or foil are provided above or on the feed table 1. It is also possible to arrange the reflex line 10 below the feed table 1 in such a way that the light beams 13 are emitted at the angle of inclination α and pass through a recess provided in the feed table 1 and closed with a transparent cover. Adapted to the course of the light beams 13, the reflective layer or reflective film is arranged above the feed table 1, for example on a crossmember 8, so that the rays striking the reflective layer or reflective film are also sent back differently from the regular reflection to the reflective line and the position of the reflective line thereon Edge 6 is mapped.
