Apparatus and process for ultrasonically identifying and coating articles having differing characteristics

摘要

Disclosed is an apparatus and process for ultrasonically identifying and coating articles having differing dimensional characteristics wherein, a series of such articles are moved in a random sequence past a predetermined point where the presence of each article is electronically sensed. At least two ultrasonic wave transmitters located at known distances from this point impinge waves on each article when it arrives at said point. One of the wave transmitters is positioned above the article. Waves reflected from the articles are received by ultrasonic receivers and are compared to and matched with similar code-number-identified wave patterns contained in a computer data base to identify each article's dimensional characteristics and select a predetermined control sequence program for a means for coating the articles. The matching code-number-identified signal selected from the data base is then transmitted to a pre-programmed coating means which applies a customized coating to the article according to its predetermined dimensional characteristics.
