Definitions
- the invention relates to a device for producing a printed image on a received by a cylinder print carrier by means of a laser whose laser writing head displaceable parallel to the axis of the cylinder on a traverse is attached.
- the invention is based on the object, a device of the aforementioned To create genus that ensures that the laser is only then ready is when there is a cylinder in front of the laser writing head and the laser writing head in the area of the applied print image is:
- this is achieved in that the traverse on the fixed Presence of a cylinder determining circuit breaker is provided and the Traverse carries two safety edges, which between them a Laserschreibkopfverstell Scheme leave blank of the width of the printed image and with a laser writing head attached another circuit breaker to shut off the outside the Laserschreibkopfverstell Anlagenes laser cooperate.
- the device shown has a cylinder 1 with at least one end flange 2 on.
- On the cylinder 1 is an (not explicitly marked here) imageable Printing form, in particular erasable printing form (or sleeve) pushed, which should be provided with a printed image 8.
- a traverse 3 is arranged, on which a laser writing head 7 is guided by means of a carriage 4.
- a support 9 for a circuit breaker 10 is fixedly mounted on the cross member 3.
- the circuit breaker 10 is as the end flange 2 contactless scanning Switch formed. It prevents turning on the laser when the cylinder 1 is not in the position provided for imaging, so at a distance a no End flange 2 is. In place of the end flange can also directly the Cylinder 1 step. Characterized in that the circuit breaker 10 a portion of the cylinder 1 scans outside of the printed image 8, this sampling is independent of Cylinder diameter and advantageous format variable with respect to the cylinder diameter used.
- a further circuit breaker 11 is mounted on the carriage 4 of the laser writing head 7.
- the circuit breaker 11 cooperates with two switching strips 5, 6, the fixed are placed on the crossmember 3.
- the circuit breaker 11 is considered mechanical formed by start-up of the switching strips 5, 6 actuated switch, but can Also designed as a non-contact switch analogous to the circuit breaker 10 be.
- circuit breaker 11 If the circuit breaker 11 is in (enable) area b, then, provided that that the circuit breaker 10 is a properly in working position Cylinder 1 has established the laser work. However, the circuit breaker is running 11 on the chamfers of the switching strips 5, 6 on the laser writing head 7 facing end face of the safety edges and thus leaves the Area b, the laser is turned off, so that the entire arrangement itself also suitable as personal protection.
- the invention is not limited to use in one of the printing press Bercisungsstation limited, but can also with devices be applied, with which the printing cylinder imaged in the printing press becomes.
