- the present invention relates to a grinding apparatus for processing a, in particular plate-shaped, workpiece, for example.
- a workpiece at least partially wood, wood-based materials, eg. Wood fibers, or similar.
- the abrasive device is a wide belt sander.
- abrasive belts used to machine a workpiece with a geometrically indeterminate cutting edge should be monitored or evaluated for wear. If such an abrasive belt worn and this condition is not or too late recognized, the grinding device is operated with a defective or inferior grinding belt on and thus produced rejects.
- the degree of wear is determined optically in a manual manner.
- the grinding belt is examined at a standstill of the grinding device by a worker and checked whether the grinding belt should be changed. Such a rating depends heavily on the level of experience of the worker and is therefore error prone.
- a judgment based on the machined workpieces is disadvantageous, because if it is recognized that the processing result is inferior, rejects are already produced. At this time, the grinding must be stopped direction and a change of the grinding belt to be made, even if the production process does not allow this without disadvantages.
- the change of an abrasive belt usually has the disadvantage that at least the grinding device, and possibly entire production lines, must / must be stopped. This is contrary to the requirement to minimize downtime as far as possible.
- the worker when changing the abrasive belt, the worker must make sure that the replacement abrasive belt is the correct spare part. In the case of a sanding belt, this is ensured by a corresponding marking, for example a number on the surface of the sanding belt facing away from the grain side. It is also possible to stock differently colored sanding belts, so that the worker can unerringly recognize a sanding belt with a certain grain size and use it accordingly.
- the aim of the present invention is to provide a grinding device for processing a workpiece and a method by which the grinding belt and / or its state can be detected, wherein according to a preferred requirement, the state of wear of the grinding belt is to be detected.

- a control device which is set up to match a detection result of the detector, in particular the detected intensity of the waves reflected by the grinding belt, with identification data of abrasive belts.
- identification data concern, for example, the grain of abrasive belts, which are divided into certain classes. It has been shown that due to different intensities / reflectivities with electromagnetic waves, different grain sizes are detected and thus a conclusion can be drawn on a correspondingly inserted grinding belt.
- the grinding device comprises a warning device for outputting an acoustic or optical signal. This warning device can be triggered if a wrong or a worn abrasive belt is detected. Thus, the reliability is increased and the production of rejects is avoided.
- the grinding device further comprises a grinding belt cleaning unit. It may, for example, hold around a Bandabblasvoriques.

- the method may include the step of displaying the detection result of the detector, in particular the detected intensity of the waves reflected by the grinding belt, by means of a display.
- the method comprises the step: outputting an optical or acoustic warning signal if it is detected that the determined grain of the abrasive belt does not correspond to a desired value, or if it is detected that the detected intensity or the degree of reflection falls below a first threshold, or alternatively exceeds a second threshold.
- the radiation preferably radar radiation
- the surface of the abrasive belt is relatively smooth, ie if the abrasive belt is worn relatively heavily, for example , then a high proportion reaches the detector, so the detected intensity is higher than with a rougher or more textured surface of the abrasive belt.
