Title: Inspection and sorting of sheet materials by photoelectric means
IPC: G01N21/89
Filed: 1958-04-08
Abstract: 885,278. Photo-electric inspection devices. NASH, P. April 8, 1958 [April 9, 1957], No. 11126/58. Class 40(3). An - inspection device for detecting defects in moving material in sheet or web form comprises an inspection head having photoelectric means for inspecting a section of the material through an aperture defining a section of the inspected surface narrower in the direction of motion of the material than at right angles thereto, a material-supporting surface adjacent to theaperture, and means for illuminating the inspected surface with lights, the aperture only admitting light reflected and diffused from the inspected section of the material and such section having a dimension in the direction of material motion of the same order of magnitude as the diameter of the smallest defect to be detected. The embodiment described comprises an inspection head 9 incorporating tubular fluorescent lamps 8 fed from a regulated D.C. supply, an aperture 7, a bank of photo-cells 6 and amplifier valves (Fig. 2, not shown) above roller 5 over which paper sheeting 2 is drawn via rollers 3, 4 to eliminate flutter and folds in the paper, the paper after inspection passing to fixed cutter 13 which in operation with rotating cutter 14 severs the paper into sheets which normally pass to layby 20; if a flaw is detected solenoid-actuated leaf 16 tilts to direct the faulty sheet to layby 19. The photo-cells are divided electrically into groups each of which is connected to amplifiers 32 and 37, the output from the latter comprises a flaw pulse 36 and noise due to paper "background" and cell shot effect; it is stated that the latter noise level is insignificant compared with the former noise level. Amplifier 37 flaw ouput actuates a thyraton or Schmitt trigger circuit to give an output pulse 43 which is fed to a phantastron the positive differentiated screen voltage of which triggers a further thyratron, Fig. 6 (not shown). To afford operation when the flaw signal arises from a weak blemish extending in the direction of paper travel integrators 41 are inserted, Fig. 5 (not shown). The further thyratron is energized by a microswitch actuated by a cam on the rotating cutter and the current through its anode circuit relay is increased momentarily by a further microswitch which is actuated when the cutting blades meet, the relay making a circuit for a further relay the contacts of which hold it self-actuated for a period long enough to retain the solenoid energized whilst at least half a paper sheet passes to the reject layby, Fig. 7 (not shown). Roller 5 may be replaced by a fixed and polished surface, friction-induced static charges then being inhibited by radio-active isotopes below the inspection surface.
