Definitions
- the invention relates to a method for monitoring blasting agent-emitting surface treatment devices and a blasting pattern control device for carrying it out.
- a blasting agent is directed onto a workpiece surface, for example by means of centrifugal wheels. Since the swirling of the abrasive in the area of the workpiece surface does not allow visual inspection during operation, the position of the impact area of the abrasive on the workpiece surface, the so-called hot spot, is determined before the workpiece treatment is started with the help of sample placed in the blasting area. Checked sheet metal sections or with a paint application, which is then removed in the area of the beam. However, these methods of checking the beam pattern are imprecise and delay the working cycle. cool the surface treatment facilities, since the aids have to be brought into the blasting area manually and removed from it again.

- These elongated measuring strips consist of layers of spring steel in various thicknesses and are attached to a workpiece or a reference plate, for example by gluing, and then subjected to the blasting agent.
- the deflection allows a conclusion to be drawn about the beam intensity and thus a more precise determination of the hot spot, but here, too, continuous monitoring of the beam pattern is not possible.
- a migrating jet during the ongoing operation of the surface treatment device is not recorded, so that it is only possible with great effort to carry out a jet image check for each individual workpiece. Without a one-off inspection, the quality of the workpiece cannot be guaranteed, and certification requirements, e.g. B. according to DIN ISO 9001 ff., Are not met.

The temperature at a measuring point can be measured using the known techniques; Inexpensive and precise temperature measuring devices are already available in large numbers on the market.
- the transfer of the measured values of all temperature sensors into the evaluation unit can take place simultaneously or sequentially with such short cycle times between the queries of the individual temperature measuring points that a total snapshot of the beam position results in real time for the viewer.
- At least some of the temperature sensors are infrared radiation receivers, which are arranged at a distance from the reference plate and which can each be focused on one of the temperature measuring points T lfi ... T m , n .
- an image of the infrared radiation on the back of the reference plate can be recorded.
