Transporter Removes Abrasive Scrap

The Case IH Foundry Plant (CIHFP) of Racine, Wisconsin, produces castings for the company’s agricultural and construction equipment. The grinding of these castings create gray iron waste fragments that must be collected and removed from the machining area to eliminate scrap build-up that interferes with efficient finishing operations. Minute airborne iron particles can sometimes find their way into sleeve and bearing compartments inside machine tools, wearing down performance and machine life.

The performance of the CIHFP axle housing grinder depends on its internal conveying system, the Model 850 air-operated transporter by Vibro Industries of Port Royal, Pennsylvania. Scrap is transported away from the machine along a product tray (or chute) fitted to the Model 850. The principle behind the transporter is its pneumatic cylinder design that operates on low air pressure to move trays back and forth at high speed, causing the material to steadily and quietly advance in one direction. On the slow-accelerated forward stroke, material is transported forward. During the rapid return-stroke, material remains stationary, thus ensuring constant movement in one direction.

The transporters run on air pressure alone; air pressure costs less to generate. Sound is also an issue, and these units operate quietly.

Vibro transporters are offered in four models and provide distinct benefits. First, their compact size fits easily into very tight spaces — making them an excellent choice for removing scrap from beneath machine tools. Second, they carry a big punch in a small package. The Model 850 weighs only 47pounds, yet it can move more than 500 pounds of load and 100 pounds of tray weight with just 3.4 cfm air consumption (certified at half the air consumption of other models). If you choose, you can also mount multiple trays to a single unit — replacing several conventional belt conveyors. And every model provides accurate control over the rate of travel speed (Model 850 offers variable speed control from 15 to 40 feet per minute).
