Abstract

PURPOSE: To correctly measure the cut length and running speed of material in non-contact method, by measuring the number of pulses and the time distance between pulses outputted from the photo sensors.
CONSTITUTION: The photo sensors 9i to 9n are located at the positions to the cutting position predetermined, the cut length a is placed at the photo sensor 9l and it corresponds to the position of the photo sensor 9l, the tip of the cut material 1 is placed at the position A, and all the photo sensors are reset when the previous cut is finished. When the material 1 proceeds at a constant speed and the tip reaches the first sensor 9i, the tip position and the running speed of the material 1 are obtained. Next, when the tip reaches the sensor 9k, the present tip position and the running speed are measured and the same conditions are repeated. When the tip of the material 1 reaches the sensor 9l, the material 1 is cut at the length a by the cut regerence. Thus, without giving damage to the material, the cut length and the running speed can be measured correctly.
