Controlling a size of rubber wires

Applicable Product: Laser Displacement Sensor Industry: Automotive Task: Measurement

Applicable Product: Laser Displacement Sensor
Industry: Automotive
Task: Measurement 


Problem

In a bead producing process at a tire factory, a sensor measures a size after wires being adhered to rubber and detects a lump of rubber or adhesive failure. With conventional sensors, it was hard to detect failure on a fast production line. In addition, it takes some time to change setting data of sensors at changeovers.

Solution

HL-T1010A
HL-AC1

 

 

 

 

 

 

Benefit

High-precision detection is possible
This sensor even detects fine changes of the amount of light; therefore, it can judge small changes of diameters. The sampling rate is 143us, which is fast. It is possible to detect failure even when objects pass fast

Automatic teaching function is equipped
Automatic teaching function is equipped, which allows you to set threshold value while objects are flowing. It is easy to set precise threshold value. Therefore, changeovers can be done very easily when objects change

Judgement function of fine or failure is equipped
Three outputs of HI-GO-LO is possible by setting upper and lower threshold value. By using it, the sensor can judge failure due to a lump of rubber as HI, non-defective as GO, and failure due to lack of adhesive as LO. This allows a quality management.
