CHICAGO — In its first show since merging manufacturing into a single, central site in Franklin, Pa., Conair Group introduced several new auxiliary machines at Plastics USA, held Oct. 6-8 in Chicago.
Sized for molding machines from 50-150 tons, the new Sepro 3010 series beam robots give injection molders the same controls and drive options as Conair's larger robots. The Sepro 3010 is intended for applications involving payloads as large as 4.4 pounds, while the 3011 is sized for as much as 6.6-pound loads. Both are designed to fit on smaller presses and have capability to program continuous, multiple-axis motion.
``This rounds out the Conair line of robots,'' said Ben Martin, group marketing and communications director for Conair, based in Emsworth, Pa., near Pittsburgh.
Standard drive configurations include all-pneumatic versions, pneumatic/AC-frequency, AC-frequency/servo combinations and all-servo designs with as many as five axes of motion for part orientation and subarm operation. The servo-driven 3010ZS and BZ versions can reach speeds of 6 meters per second.
A rotating disk is the key feature in the new BAF series throat feeder, according to Conair.
Small openings in the disk hold a precise volume of material, which is dispensed as a disk rotates. By changing disks and varying the speed of rotation, the feeder can handle a wide range of feed rates, from as little as a fraction of a gram per second to as much as 180 pounds per hour. Conair touts the feeder as ideal for molding machines 100 tons and smaller or for extruders with screw diameters to 2 inches.
Conair's new midrange CF series press-side granulators fills the gap in one of the broadest lines of granulators in the plastics industry, Martin said. The machines are available in a standard open-rotor configuration, which is ideal for film, thin-wall containers and other lightweight plastics. An optional closed-rotor design has helical segmented knives, providing cutting power to handle heavier materials and scrap.
With rotor speeds from 300 rotations per minute to 500 rpm, the CF series fills out the middle range between low-speed units that operate around 150 rpm and high-speed granulators that run from 500-1,000 rpm. The machine's throughput is 350 pounds an hour. Motors range in size from 5-15 horsepower.
In addition, processors now have the option of choosing quick-change, bolt-on knife tips and/or a general-purpose open rotor on the LP and JC series granulators.
Conair claims to be the world's largest and fastest-growing supplier of auxiliary equipment. The company manufactures heat-transfer systems and temperature-control equipment, resin-handling equipment, robots, size-reduction and scrap-reclaim machinery, pelletizers and downstream extrusion systems for profiles and tubing.
