Title: Inspecting tablets esp. nuclear fuel pellets - by passing individual rotating tablets through laser and linear camera fields
Inventor: OSSEFORTH EWALD
IPC: G01B11/00
Filed: 1991-07-23
Abstract: (A) Optical inspection of tablets (TB) is carried out by using two rotating shafts for axial rotation of the tablets past a slit in one of the shafts which delimits a viewing field for a laser beam, a radiation detector being used to provide a computer processable signal. The novelty is that (a) the speed of the foremost tablet (TB) of a row, coming from e.g. a grinding machine (S), is compared in a control computer (SR) with the speed of a catch (M) of an entrainment system (MS) and if required, a cooperative belt system (G1-3), acting on the tablet, is accelerated so that one tablet (TB) is entrained by one catch (M); (b) the isolated tablets (TB) are pushed onto the shafts (RW1, RW2) by the catches (M) and are passed individually through the viewing field; (c) the optical system, associated with the gap, transmits tablet measurement data to an evaluation unit (MSA) for comparison with stored target values and for transmission of the result to a computer (PC); (d) the tablet (TB) is illuminated (BL) in a further observation station and images of its surface are recorded by a linear camera (KMC); (e) the recorded images are fed from the linear camera (KMC) to the evaulation unit (MSA) for comparison with stored target values and for transmission to the computer (PC); (f) the tablet comparison data, transmitted to the computer (PC), are compiled and the computer (PC) passes faultless tablets (TB) for further use, sorts out defective tablets and/or controls the grinding machine (S) so that faults observed during grinding are rectified on grinding further tablets. (B) Equipment for inspecting the surface, roundness and dimensions of tablets is also claimed. USE/ADVANTAGE - The process is used esp. for inspecting nuclear fuel pellets. It provides accurate and detailed tablet inspection, simple and precise handling and reliable operation.
