Parts washing unit for MANUFACTURER OF ACCESS HARDWARE to remove polishing compound from various types of screws.

Thoroughly Wash and
Dry Large Volumes of
Various Screw Types
to Increase
Production Time

BACKGROUND
This 100 year-old company designs and manufactures the industry's broadest range of latches and access hardware for use in a diverse variety of applications. This application involves the following types of screws: torx, phillips, slotted, recessed, cross-recessed, and captive hardware.

PROBLEM
Their old parts washer could no longer keep up with production, was not removing the polishing compound adequately, and was labor intensive. Designs for a new cleaning system had to meet the following requirements: a) adapt to the customer's trays which hold any type of screw made, b) remove 100% of the polishing compound that is often hardened and always packed into the head slots, and c) wash, rinse, and dry the trays in a continuous fashion...output one (1) tray every 30 seconds.

SOLUTION
A Carousel system with wash, rinse and dry zones. This system has 17 individual fixtures. Each fixture has a hinged screen on the top and thick side walls with milled grooves every 3/16" ...the smaller the screws, the closer the tray is positioned to the top screen so that the screws are not blown off the trays. The turntable rotates once every 8 minutes, outputting one tray / 80 screws every 30 seconds or 9,600 screws per hour.

SYSTEM
A SS C-7000 PCS (Carousel with 70" turntable) with the following features: operator access on the left due to the room layout, regenerative blower with air heat system for drying, mist-kop steam collector, and an ELE-500 PLC.
