Abstract

The present system comprises a thickness-measuring device and a sorting device based on the measurements provided by the measuring device. The measuring device comprises two non-contact probes mounted opposite each other, between which is conveyed the part whose thickness is to be measured. Measurement is done by comparing the sum of the measurements provided by both probes to a corresponding sum obtained from a known master gauge. Referring to the figure, part 1, whose thickness is to be measured, is brought to the measuring station by a conveyor 2 and is detected by proximity detector 3 when in proper position for measurement. The signals from detector 3 are used to indicate to programmable controller 4 when to take the measurement data into account.

Automatic Part Thickness Measuring and Sorting System

The present system comprises a thickness-measuring device and a sorting device based on the measurements provided by the measuring device. The measuring device comprises two non-contact probes mounted opposite each other, between which is conveyed the part whose thickness is to be measured. Measurement is done by comparing the sum of the measurements provided by both probes to a corresponding sum obtained from a known master gauge. Referring to the figure, part 1, whose thickness is to be measured, is brought to the measuring station by a conveyor 2 and is detected by proximity detector 3 when in proper position for measurement. The signals from detector 3 are used to indicate to programmable controller 4 when to take the measurement data into account. Non-contact probes 5 and 6, mounted on opposite sides with respect to part 1, provide measurement values X and Y, respectively, which are summed and converted into BCD (binary coded decimal) form by electronic circuit 7, and then transmitted to controller 4 through interface circuit 8. Controller 4 compares the sum S = X + Y to the sum So = Xo + Yo obtained from the measurement of a known master gauge. The difference S - So represents the amount by which the measured part thickness differs from the master gauge. Controller 4 then processes the necessary signals to drive handling equipment 9 to the appropriate thickness group position where the part is deposited....
