Annularly Aligned Coil Differentiation

Setting mistakes resulting from human intervention can result in different product types being mixed up; however, coils with different capacities must not be mixed together. Space is limited because the detection is carried out when the coils have been set with the annular alignment machine. A small size is therefore beneficial and greatly reduces the man-hours spent on design. In addition, since the vision sensor is used only to determine the lengths of the three product types, a simple setup is required.
