Non-contact Measurement Type Automatic Sorting Machine for Cylindrecal Rollers

Directed at inefficiency and high error rate of bearing roller manual sorting and limited measuring range of sorting machine,a new kind of automatic sorting device is developed for cylindrical roller.The measurement error is reduced effectively by using non-contact measurement,and the efficiency of roller sorting reaches 120~150 emp by using double row feeding device,which meets the demand of rapid and accurate sorting.Besides,an error analysis is made which roundness,cylindrical error,and impurity are generated in measuring procedure,and some advices are given to avoid and decrease them.
