Geiger Handling Systems AG, an automation supplier and system integrator based in Schwarz-enburg, Switzerland, coordinated a turnkey system at a clean-room medical molder.
The company, which Geiger did not identify, molds pharmaceutical containers on one injection press, covers on another press, then assembles the parts, all in a Class 100 clean room.
Each injection press has its own StÃ¤ubli RX 130 articulating-arm robot with vacuum grippers. One challenge was removing and assembling the dissimilar parts within the cycle time of the two presses — 23 seconds for the first mold, and 13 seconds for the other mold. The takeout interval time was two seconds to remove four containers and four covers.
The two robots transfer the injection molded parts to the center of the cell, where the covers and containers are assembled. Then one robot places the assembled containers onto a conveyor belt, which takes them to a Class 1,000 clean room for more processing.
The complete system includes waste parts chutes, vacuum grippers and monitoring equipment and all parts handling.
