Robotics for perfectly sharpened knives
Precisely sharpened knives lower the risk of accidents and reduce work absence associated with arm and shoulder inflammation. According to Knecht Maschinenbau (Bergatreute, Germany), hand knives that are sharpened using E 50 R robotics can increase the meat yield by up to 0.5 percent compared with manually sharpened knives. The central organ of the fully automated E 50 R Hand Knife Sharpening Machine is the six-axis robot.
The robot is completely enclosed (IP65) and designed for harsh environmental conditions. Before the sharpening program starts, every single hand knife is optically measured at a laser station. The detected knife shape is converted into CNC data. The robot uses this data to guide the knife through the sharpening process. As a result, the original knife shape is maintained with each re-sharpening process.
The sharpening process takes approximately 40 seconds per knife. The steps are as follows: the six-axis robot takes the knife out of the magazine – the knife shape is optically measured – the knife is sharpened, deburred and polished – the robot returns the knife to the magazine. The knife magazine consists of two boxes and has space for a total of 60 knives. It can be loaded outside the machine during the operating process.
The E 50 R can sharpen up to 650 hand knives per 8-hour shift, depending on the shape and size of the knives. One to two hours of staff time are required.
The E 50 R is completely encapsulated. In addition, the water-cooling system and suction unit that come with the standard model significantly reduce all emissions that are produced in the sharpening and polishing processes. This protects the operator’s respiratory system. The sharpening and grinding dust that is filtered out of the air can be easily disposed of in an environmentally friendly manner.
