Title: Blemish detecting apparatus
IPC: G01N21/89
Filed: 1969-04-18
Abstract: 1,220,901. Blemish detecting apparatus. MANDREL INDUSTRIES Inc. April 18, 1969 [April 19, 1968], No.20013/69. Heading G1H. In an apparatus for detecting blemishes on a surface 12 the small portion of the surface imaged on and therefore "seen" by, a photo-cell 13 is continuously varied by the rotational movement of the mirror device 14, which results in a series of scans across the surface, the output of the photocell being normalized on alternate scans. As shown, light from the surface 12 is reflected from a facet of the octagonal mirror 14 and a plane mirror 21 and is focused by a lens 19 onto an aperture 18, behind which is located a photo-multiplier or solid state photo-cell 13. A light source, and lens-and-prism combination are located adjacent each side of the mirror to provide illumination for the object Fig.2, (not shown). As the mirror 14 is rotated anticlockwise in Fig. 1, the beam 31 received at the aperture 18 sweeps across the surface from left to right, and this mirror movement is linked to the movement, out of the plane of the figure, of a conveyer 36 so that a continuous strip of material may be inspected. When the beam 31 encounters a blemish, the illumination of the photo-multiplier is altered, and the resulting altered voltage signal is fed to a voltage detector which indicates the presence of a blemish. A gating circuit is provided Fig.3 (not shown) to ensure that the voltage detector is not operative when the beam 31 sweeps beyond the edges of the surface 12, the operating pulses for this gating circuit being provided by a photo-cell 48 which receives light from a lamp 47 at a given orientation of each facet 22. The pulses from the photo-cell also control a normalizing or calibrating circuit Fig. 3 (not shown) so that during every alternate scan the photo-cell output is normalized to maintain a constant reference level equivalent to the intensity of radiation that has fallen on the photo-cell during each such "normalizing" scan. Thus, during a measuring scan, voltage fluctuations from the level set during the previous normalizing scan are recorded. So that no blemishes are missed during this calibration process, the conveyer 36 moves the surface approximately half the width of the aperture 18 for each sweep of the beam 31. In a further embodiment Fig. 5 (not shown) a diffused glass screen (201) is provided whose illumination is the same as that of the surface 12, so that if the beam overshoots a wrongly positioned surface during a sweep, no spurious signal is received by the voltage detector. In this embodiment, a further optical system is provided to scan up and down one side of an object, the optical system and its associated detecting circuitry being substantially identical to that already described. The apparatus of the invention may also be used to investigate material placed around a rotating drum or a plurality of discrete objects on a conveyor, and the voltage detector may be coupled to a sorting or rejection device.
