The present invention relates to a stainless steel manufacturing equipment, and more particularly, to an inner and outer diameter measuring apparatus of a sleeve used as a core when winding a rolled thin plate in the form of a coil.

In general, in the case of thin sheets (less than 0.3 mm in thickness) among the rolled products produced in the cold rolling process, the tension reel is prevented to prevent the steel sheet from loosening or internal buckling due to the weakening of the winding tension during initial winding. The top of the steel sheet is wound on a mandrel of a tension reel, and a cylindrical sleeve made of steel is loaded immediately before winding in a coil form.

These sleeves are transported to the vicinity of the winder on which the tension reel is installed by using a coil car for transporting the coils, and then inserted into each mandrel by a worker by hand.

When the sleeve is inserted into the mandrel, the sleeve corresponding to the diameter of the mandrel should be selected so as to be easily inserted. In this case, the inner and outer diameters of the sleeve are measured manually to facilitate the insertion.                         

However, when the operator measures the inside and outside diameter by hand, the measured value is not constant, and when attempting to charge the sleeve based on the measured value, if the diameter of the mandrel and the inside diameter of the sleeve do not match, the work must be reworked. There is also a problem that the work efficiency is also reduced.

In the process of measuring the inner and outer diameters of the sleeve, contaminants are removed from the inner and outer circumferential surfaces of the sleeve. The reason is that if the thin plate is wound on the sleeve while the sleeve is contaminated, the thin plate to be released into the product is contaminated.

This decontamination of the sleeve is also performed by a worker's manual work as in the inside and outside diameter measurement. Therefore, there is a problem that the cleaning is not cleaned and the cleaning work is excessively timed and the work efficiency is deteriorated.
