ABSTRACT:
A sheet metal washer system for cleaning metal blanks includes a washer cassette with an open bottom that is selectively mounted on a tank assembly, a drive motor assembly and a filter assembly. The washer cassette includes an inlet opening and an exit opening with upper and lower entry rollers having a first predetermined durometer positioned adjacent to the inlet opening and upper and lower exit rollers having a second predetermined durometer positioned adjacent the exit opening. Upper and lower manifolds for delivering cleaning fluid from the filter assembly to the interior of the washer cassette are positioned between the entry and exit rollers. The sheet metal blank is cleaned by the entry rollers and dried by the exit rollers, as it passes through the sheet metal washer. The washer cassette preferably includes a safety mechanism for locking the upper entry and exit rollers into a storage position when the washer system is not in use. The washer cassette preferably further includes at least one quick disconnect air and fluid connection plate to permit one-step removal of all air and fluid lines from the washer cartridge. An optional exit spray system for coating the sheet metal blanks after being cleaned may be integrated within the washer cassette.
