Abstract

A sawing apparatus includes a separating saw blade of a separating saw and a scorer blade of a scorer. Through an adjusting device, the position of the scorer blade can be adjusted transversely in relation to a sawing direction. The sawing apparatus has a sensing device which can sense the relative position of a scoring groove of the scorer blade on a workpiece with respect to a separating groove of the separating saw blade, and/or the quality of the separating groove.

Claims (20)

1. A sawing device comprising:

a cutoff saw;

a scorer positioned in front of the cutoff saw;

a remote controlled adjusting device for adjusting the position of the scorer transversely to a sawing direction and transversely to a plane of the scorer;

an acquisition device, which on a processed workpiece acquires measurements of at least one of:

an actual relative position of a scoring groove produced by the scorer to a separating groove produced by the cutoff saw; and

stripping of the separating groove,

wherein the acquisition device comprises an evaluation device, which evaluates the strippping; and

a controller that receives signals from the acquisition device and adjusts the scorer relative to the cutoff saw based on at least one of the acquired position and stripping measurements.

2. The sawing device according to claim 1 , characterized in that the acquisition device comprises image capturing.

3. The sawing device according to claim 1 , characterized in that the acquisition device comprises a laser scanning device.

4. The sawing device according to claim 1 , characterized in that the acquisition device comprises an ultrasonic scanning device.

5. The sawing device according to claim 1 , characterized in that the acquisition device comprises a monitor, on which the relative position of the scoring groove to the separating groove can be visualized.

6. The sawing device according to claim 1 , characterized in that the sawing device has a controller, which controls the adjusting device and thereby automatically adjusts the acquired actual relative position to a target relative position.

7. The sawing device according to claim 1 , characterized in that the controller controls the adjusting device and thereby automatically adjusts the acquired actual relative position so that stripping of the separating groove is reduced.

8. The sawing device according to claim 1 , characterized in that the cutoff saw and/or the scorer and at least a part of the acquisition device are disposed on a common traveler.

9. The sawing device according to claim 1 , characterized in that at least a part of the acquisition device is disposed on a separate displaceable cart.

10. The sawing device according to claim 1 , characterized in that the acquisition device acquires the scoring groove and the separating groove in a plane that is orthogonal to the sawing direction.

11. The sawing device according to claim 1 , characterized in that the acquisition device acquires a top view of a region of the scoring groove and of the separating groove on the processed workpiece.

12. The sawing device according to claim 1 , characterized in that the evaluation device evaluates undulated cuts.
