Title:
STEEL BAR COUNTING DEVICE
Document Type and Number:
Japanese Patent JP2010140431
Kind Code:
A
Abstract:

To provide a steel bar counting device for achieving a highly reliable counting function in the case of counting the number of steel bars from the photographic image of one end face of an arbitrary bundle of banded steel bars by reducing a missing rate with respect to the end face having non-uniform directions.

A low angle illumination part 10 scatters and emits the rays of light to one end face of banded bar steels PA from a peripheral oblique direction, and even when one end face of the arbitrary bundle of banded bar steels PA has non-uniform directions, it emits the rays of light to one end face of all the bar steels PA. Thus, even when one end face of the arbitrary bundle of banded bar steels has the non-uniform directions, it is possible to acquire the end face image of the bar steels having an area determined as the bar steels by placing an image pickup camera at a position extended by an optical path extending means.
