Title: Tip profile detector for band material
Inventor: YOSHIKAWA HIROBUMI
IPC: G01B11/24
Filed: 1992-11-05
Abstract: PURPOSE:To provide a detector for detecting tip or tip profile of a band mate rial, e.g. a coiled band of steel plate or paper, being used in production facility in which a following process, i.e., a cutting work, is automated by providing a unit for determining the direction of the tip of band material thereby deciding whether the direction must be changed or not prior to entering the cutting work. CONSTITUTION:A coiled band material 1 is placed at a position shown on the drawing and a rotary unit 3 is operated to rotate the band material in the arrow direction. Light is then projected from an illuminator 4 to produce a shade at the tip part 2 of the band material and the shade is imaged by means of a CCD camera 5 which then delivers an image signal 7 to an image processor 8. The image processor detects the shade produced at the tip of the band material based on the image signal 7 thus detecting the tip profile. A tip profile signal 9 is delivered to a direction deciding unit 10 where the tip profile is approximated by a quadratic curve based on the tip profile signal 9 thus deciding the tip direction.
