Function
The material can be scanned using up to three line scan cameras and a scanning frequency of up to 10 kHz. With "simple" hole detection, the width of the holes is measured and a warning or an error is output to the customer's PLC if an adjustable tolerance limit is exceeded. With hole inspection, the size (area) and position of the holes detected is also determined in relation to the material transport and saved in a PC. Highquality precision camera lenses are used to determine accurately the sizes of the holes during the hole inspection. Reel logs can be produced and the holes detected displayed as a 2-D image using the E+L PC software.
Area of use
The hole and splice inspection system is used in roller-head lines and tire building machines for carcass control ahead of the drum.
Application
It is necessary to interrupt the conveyor belt for hole and splice inspection systems. The web is measured using transmitted light and its height must not fluctuate at the measuring point.
