Yushin Precision Equipment introduces the first two models of the new “HSA” series of high-speed traverse-type servo-powered take-out robots for injection molding. The HSA demonstrated world-class take-out time of only 0.27 seconds at a recent live molding exhibition, and now the first two model sizes of the HSA series officially go on sale in Japan on December 6th. Yushin Precision Equipment carries the motto of “Heartful Technology”, and is a dedicated supplier of take-out robots for injection molding machines (based in Kyoto, Japan; President Mayumi Kotani; 1.986 billion yen capital).
Yushin conceived the HSA as an all-new high-speed take-out robot with superior production value, and employed the cutting-edge process of design optimization*1 to rid the robot of as much weight and bulk as possible while still maintaining high rigidity.
The HSA features the following three strengths:
1) Optimal Lightweight Design to Enhance High-Speed Operation
The use of design optimization produced a 13% lighter robot and enables faster speeds.
The HSA’s live molding take-out time of 0.27 second was 25% faster than its predecessor,
the RAII-a-HS robot.
2) Slimmer Arm Fits through Narrower Mold Openings
A robot’s wrist lies at the extremity of its arm and enters the mold during take-out.
Re-engineered with design optimization, the HSA’s wrist is 38% slimmer than previous Yushin models, allowing mold openings to be 41mm narrower and thereby enabling faster molding cycles.
3) Enhanced Stability through Vibration Control Technology
The HSA integrates vibration suppression technology throughout its design. Further, its arm is reinforced with carbon-fiber reinforced plastic material for superior vibration dampening. This combination results in the smooth motions necessary for the HSA’s extremely high speeds.
Yushin President Mayumi Kotani had the following comments regarding the HSA series:
We posed ourselves the question “Why is a massive, several-hundred kilogram robot needed to take out a plastic part weighing just a few hundred grams?” and to answer it, we applied the process of design optimization to pursue the most suitable robot form possible. The result of that endeavor was the HSA, a robot with speed and stability performance beyond that of all its predecessors.
Design Optimization is a process we co-researched together with Kyoto University. We first applied it to optimize an end-of-arm-tool, which you could say is like the robot’s “hand.” The optimization lowered the tool’s overall weight and shortened any “flutter” of tool extremities to make smoother, faster take-out of molded parts possible.
Yushin premiered the HSA robot at our booth at the K2010 tradeshow*2 atop a high-cycle injection molding machine, removing plastic cellular phone housings from a 2-cavity mold at the extremely fast take-out time of 0.32 second. One factor for the HSA’s extreme speed was its lightweight, extra-rigid vertical arm, optimally designed to be rid of unneeded mass and grafted with carbon fiber reinforced plastic for low weight and high strength.
This high-performance design would not have been possible using the tried-and-true design philosophies of the past. Rather, it was a synthesis: computer-simulation-aided theoretical insight combined with several decades of Yushin design know-how. Theory and practice applied together toward perfecting the ultimate robot that is the HSA series. This series was made by bringing new procedures to bear on the original Yushin founders’ design theme of ever lighter, ever faster, and I believe it will herald in a whole new generation of take-out robots.
The two new HSA models being released are the HSA-150, sized for injection molding machines of 100-220tf (tons), and the larger HSA-250, for 180-300tf molding machines.
