rechnergesteuert

computer-controlled

Alle Ar­ beitsgänge werden rechnergesteuert koordiniert und seitlich optimiert.

All operations are coordinated and optimized with respect to time by computer control.

Das System ist nicht rechnergesteuert , eine derartige Umruestung ist jedoch nicht ausgeschlossen .

The technology is not processor based , but this is not excluded .

Dann werden die Laserschweißköpfe 20 rechnergesteuert außer Funktion gesetzt.

At that point the controller deactivates the laser welding heads .

Eine weitere Aufgabe der Erfindung besteht darin, das Sehtestgerät so auszubilden, daß es rechnergesteuert betrieben und somit der Prüfungsaufwand erheblich reduziert werden kann.

A further purpose of the invention is to provide a vision-testing device in such a manner that it can be computer-controlled operated and thus the testing input can be significantly reduced.

Für die Optimierung des Belichtungsprozesses bieten die als Belichtungsmaschinen verwendeten Photostepper die Möglichkeit an, die Belichtungsstärke oder -dosis, die Fokussierung und die Positionierung der Halbleiterscheibe auf dem Auflagetisch kontinuierlich rechnergesteuert oder manuell zu verändern.

In order to optimize the exposure process, the photosteppers used as the exposure machines offer the possibility of changing the exposure intensity or dose, the focusing and the positioning of the semiconductor wafer on the support table continuously, manually or under computer control.

Durch einen einfachen Mechanismus einer verdrehbaren Drehscheibe, die außerdem in X- und/oder Y-Richtung verstellt werden kann, kann also die darauf aufliegende Druckplatte - durch die Verknüpfung der Ansteuerung mit dem Rechner oder Computer - rechnergesteuert auf zu erwartende und empirisch ermittelte Papierfehler, also den "fan-out", eingestellt werden, so daß die Druckplatte von vorneherein die entsprechenden Verformungen hat, die bei der Befestigung an der Druckwalze dazu führen, daß die Druckplatte der Papierverformung gemäß versetzt an der Druckwalze befestigt wird. Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher beschrieben.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS An exemplary embodiment of the invention will be described in greater detail below with reference to the drawings in which, in schematic form, FIG. 1 is a view of altogether four printing rolls arranged one after the other in the direction of feed, each bearing eight printing plates, whereby the paper web to be printed and particularly its side edges at the left and right of the end faces of these printing rolls are represented in dot-dash lines, whereby the lines extending parallel to one another indicate an ideal paper web, while the lines diverging outwardly therefrom from bottom to top represent the paper deformation during passage between printing rolls from bottom to top, FIG. 2 is a side view and FIG. 3 is a plan view of a stamping and/or bending machine in which the printing plates to be mounted on the printing rolls are provided with deformations, namely peripheral bends for their mounting and stampings for exact adjustment on the register pins of the printing rolls, FIG. 4 is a printing plate which at its two opposed edges is provided with stampings for register pins, whereby adjacent to said stampings there are marks shown which were applied before the deformation of the printing plate and serve for accurately aligning the printing plate in the stamping and/or bending machine with the aid of video cameras, FIG. 5 is the field of view of such a video camera before the mark and thereby the printing plate is positionally correctly aligned, FIG. 6 shows the various aligning movements for the printing plate in two directions X and Y at right angles to each other and in the direction of rotation Z, FIG. 7 is a representation corresponding to that of FIG. 5 of the field of vision of one of the video cameras once the mark of the printing plate has been brought into coincidence with the corresponding setpoint in the video camera, FIG. 8 is a representation corresponding to that of FIG. 4 of a printing plate in which the stampings are displaced in relation to the exact arrangement in FIG. 4 so as to allow for a paper error at the location of a printing roll at which this printing plate is to be mounted, again showing next to the stampings the marks or register crosses for cooperating with the correspondingly adjusted video camera, FIG. 9 is the field of vision of the video camera with the central register cross of the zero position in the video system and, displaced in relation thereto, the off-center register cross as mark of the printing plate which has been pre-aligned but not yet accurately adjusted, FIG. 10 is a representation corresponding to that of FIG. 7, in which the two marks of FIG. 9 coincide, FIG. 11 is the field of vision of the video camera after a correction to allow for the paper error and FIG. 12 is a scheme for the empirical determination of paper errors or deformation, i.e. fan-out data, for a computer controlling the stamping and/or bending machine and its positioning device.

Dabei sind alle Auflagestellen jeweils einzeln quer zum Band in Richtung Banddicke rechnergesteuert verstellbar.

All the support points are adjustable individually perpendicular to the strip in the direction of strip thickness.
