The knife is put onto a module which turns 360°. A laser scanner records measurement values continuously during the turn. At the same time the edge is observed with a linescan camera. Results from both processes are evaluated by the software and presented in a user-friendly way.
The movable axis positions the sensors in front of the knife edge, thus compensating for diameter differences.
Camera and laser observe the edge during the entire turn.
The system provides objective results while the typical nail check depends on the experience of the person and their subjective impression.
The grinding process and the knife exchange is economically efficient due to the measurement values. The abrasion becomes predictable and the knife itself is used optimally. In addition, the measurement module can be connected to the customer’s PLC. Thus, measurement values can be transferred to any CAQ system (such as SAP, databases, etc.).
A major advantage of the optical check is the improved security of the operator. Accident hazards are drastically reduced by the automatical turn and less contact. The operator only changes the knife.
The automatic measurement provides comprehensive data in only 10 seconds. All values are saved within the system to be assigned exactly to each knife to prove its quality. Results are documented consistently and stored as Excel-readable files.
