Conveyor indexing parts washers utilize custom fixtures attached by chains to hold manufactured parts securely and in precise positions or orientations for washing, rinsing, and drying in a start/stop conveyor movement. Part fixtures consist of a stainless steel plate with non-metallic material at part contact points. Fixtures can be designed to hold one part or multiple parts depending on the cleaning application. A profile plate may be utilized at the load end of the washer to verify correct part loading on the fixture. Spray manifolds with strategically positioned nozzles are utilized for flushing out part features such as blind holes, passageways, hidden cavities, and leading/trailing surfaces. Drying is accomplished through the use of high-pressure blowers and timed compressed air for dislodging moisture from part cavities. Moving manifolds and probing devices can also be incorporated for cleaning hard-to-reach areas. The benefit of using part fixtures and indexing is that it allows the cleaning system to specifically target part features that require critical cleaning.
Alliance’s Indexing parts washers can be engineered to run in either manual mode or designed to be integrated with robotic load/unload automation devices. Indexing is accomplished through the use of a servo drive conveyor system and sensors to seamlessly communicate with automated loading and/or unloading devices. Sensors also aid in holding tight position tolerances. Electrical controls can be supplied to specification and the machines can be designed to interface with mating equipment, as handshake synchronization is an integral feature of all Alliance industrial cleaning equipment. Our indexing conveyors have the technology to account for accurate part positioning, maintain proper cycle times, and account for chain stretch; all critical to the operation of an indexing parts washer.
Indexing parts washers are used to clean parts such as a gear, brake caliper, oil pump housing, oil pan, drive shaft, engine cover, and more. Indexing is especially beneficial for automotive components where cleanliness is critical.
