Description
Die Erfindung betrifft ein Verfahren zur Bestimmung der Position zum Anbringen eines Kennzeichens an einer Seitenwand eines Fahrzeugluftreifens mittels eines um eine Drehachse drehbaren Laserschreibkopfes, wobei die Drehachse des Laserschreibkopfes bezüglich der Drehachse des Reifens zentriert wird und die Winkelposition des aufzubringenden Kennzeichens durch Abtasten/ermessen der Seitenwand nach dem Lichtschnittverfahren rechnerisch ermittelt wird.The invention relates to a method for determining the position for attaching a mark on a side wall of a pneumatic vehicle tire by means of a rotatable about a rotation axis laser writing head, wherein the axis of rotation of the laser writing head is centered with respect to the axis of rotation of the tire and the angular position of the applied mark by sensing / measuring the side wall is calculated by the light-section method.
Die Seitenwände eines Reifens werden üblicherweise während der Vulkanisation des Reifens in einer Vulkanisationsform mit den vorgesehenen Beschriftungen, beispielsweise dem Markennamen, Dimensionsangaben und dergleichen, versehen. Diese Kennzeichen sind als Erhebungen oder Vertiefungen in den Seitenwänden des Reifens ausgebildet und als solche sichtbar. Es kann jedoch erforderlich sein, in den Seitenwänden des fertigen Reifens Kennzeichen anzubringen. Dazu wird insbesondere ein Laserschreibkopf verwendet, welcher Kreisbewegungen folgend das Kennzeichen aufbringt. Die Winkelposition des Kennzeichens wird durch Vermessen der Seitenwand mit einem Laser nach dem Lichtschnittverfahren durch einen Bildvergleich Soll-zu-Ist bestimmt, wobei als Referenz beispielsweise die vorhandene Seitenwandbeschriftung dient. Der das Kennzeichen aufbringende Laserschreibkopf wird durch entsprechende optische und/oder mechanische Hilfsmittel bezüglich der Drehachse des Reifens zentriert.The sidewalls of a tire are usually provided with the prescribed labels, for example the brand name, dimensions and the like, during the vulcanization of the tire in a vulcanization mold. These marks are formed as elevations or depressions in the side walls of the tire and visible as such. However, it may be necessary to affix license plates in the sidewalls of the finished tire. For this purpose, a laser writing head is used in particular, which circular motions following the indicator applies. The angular position of the mark is determined by measuring the side wall with a laser according to the light-slit method by an image comparison target-to-actual, for example, the existing sidewall caption serves as a reference. The license plate applying laser writing head is centered by appropriate optical and / or mechanical aids with respect to the axis of rotation of the tire.

Es hat sich nun herausgestellt, dass eine exakte Zentrierung des Laserschreibkopfes oftmals nicht möglich ist, beispielsweise in Folge von Ungenauigkeiten einer mechanischen Zentrierung, sodass sich das aufgebrachte Kennzeichen nicht in der erwünschten Sollposition befindet.It has now been found that an exact centering of the laser writing head is often not possible, for example, as a result of inaccuracies of a mechanical centering, so that the applied indicator is not in the desired desired position.
Hier setzt nun die Erfindung ein, deren Aufgabe darin besteht, sicherzustellen, dass sich das nachträglich durch den Laserschreibkopf aufgebrachte Kennzeichen in der erwünschten Sollposition befindet.Here is where the invention begins, whose task is to ensure that the subsequently applied by the laser writing head indicator is in the desired desired position.
Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, dass beim Vermessen/Abtasten der Reifenseitenwand mittels des Lichtschnittsensors ein an der Seitenwand konzentrisch zur Reifenachse kreisförmig umlaufendes Element zur rechnerischen Bestimmung des Mittelpunktes bzw. der Drehachse des Reifens herangezogen wird, ein etwaiger Versatz der Drehachse des positionierten Laserschreibkopfes zur rechnerisch bestimmten Drehachse des Reifens ermittelt wird und der Laserschreibkopf das Kennzeichen unter Berücksichtigung des berechneten Versatzes anbringt.The object is achieved according to the invention in that when measuring / scanning the tire sidewall by means of the light section sensor is used on the side wall concentric to the tire axis circular rotating element for mathematical determination of the center or the axis of rotation of the tire, any displacement of the axis of rotation of the positioned laser writing head is determined for the computationally determined axis of rotation of the tire and the laser writing head attaches the indicator taking into account the calculated offset.
Die Erfindung gestattet es somit, die Position des Laserschreibkopfes bei Bedarf zu korrigieren, sodass das Kennzeichen an der gewollten Stelle aufgebracht werden kann.The invention thus makes it possible to correct the position of the laser writing head, if necessary, so that the mark can be applied at the desired location.
Es ist von Vorteil ein oder mehrere in/an der Seitenwand vorhandene(s) kreisförmige(s) Element(e) zur rechnerischen Bestimmung des Reifenmittelpunktes, beispielsweise eine Felgenschutzrippe oder eine Designbegrenzung, heranzuziehen. Selbstverständlich ist es auch möglich, gesonderte Elemente an der Seitenwand anzubringen.It is advantageous to use one or more circular (s) element (s) in / on the side wall for mathematical determination of the center of the tire, for example a rim protection rib or a design limitation. Of course, it is also possible to attach separate elements on the side wall.
