Yushin Officially Launches 4 Models of New “RC Series” Robots

January 29, 2009 Yushin Precision Equipment Co., Ltd.

Yushin established a wholly-owned subsidiary “Yushin Precision Equipment announces the “RC Series” of traverse-type, fully servo-powered take-out robots for injection molding, which were designed to embody the concepts of Speed, Reliability, and Efficiency.  Four models of RC robots officially go on sale on February 2nd.  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) The RC series is designed as an all-around upgrade and successor model line to Yushin’s high-end “RA series” take-out robots. The four production models of RC robots are designed to match different sizes of injection molding machines.  The “RCII-100” is for injection molding machines with clamping forces of 80-130 tons.  The “RCII-150” accommodates machines of 100-220 tons.  The “RCII-250” fits machines in the 180-300 ton range, and the “RCII-400” is sized for 280-450 ton presses.  Each model is available in the single-arm “S” type for molded product take-out only, or a dual- arm “D” type for removal of both products and runners.  Each model also features 2-stage, telescoping arms which reduce the robots’ vertical profile and allow for faster operation and use in low-clearance areas. Three development concepts commanded the RC Series design: 1. Speed As higher speed and faster take-out times (shorter mold-open times) directly correlate to higher productivity, the servo motors powering the vertical and kick axes are both a full size larger than the previous robot line.  This increased power delivers take-out times up to 10% faster than previous robots, ensuring an increase in production speed. 2. Reliability The RC Series is designed for ease-of-use, with careful consideration given to both robot operators and maintenance/repair technicians in order to make their jobs easier. 　　a) Increased Structural Rigidity of Robot In seeking to perfect each beam’s cross-sectional design, structural analysis was applied and the linear guide rail layout repositioned.  The geometrical moment of inertia in torsion directions was improved by a factor of 4.5.  Thus, nuisance errors (interrupt) such as missed take-outs or inaccurate inserts have been reduced even further than before, and customers will enjoy higher work efficiency. 　　b)Arm Vibration Suppression The RC series features active “vibration suppression” on each powered axis.  By taking prior measurements of resonance frequency (fr) of moving components before each position along the powered axes, the control system reduces electrical output to the servo amplifier in roportion to torque, in order to prevent any torque effect (and corresponding shake/vibration) from occurring.  Furthermore, the control system of the RC Series adapts to factors such as position and payload and monitors a data chart of specific frequency intervals (fri) at every step during the operation cycle to help regulate smooth operation.  The end result is a dramatic reduction in wasted time waiting for shaking or vibration to cease during take-out, product release, or insert modes. 3. Efficiency With the newly-developed “ECO Vacuum” (patent pending) option, electricity usage is reduced and much less compressed air is necessary. The RC Series’ “E-Touch II” controller features a 10.4 inch full-color touch screen.  It is fully backwards-compatible with the previous model “E-Touch Web” controllers and shares the same basic operation, so teaching data created for RA-a robots may also be used freely with RC robots.  Outstanding features of this new controller include: The Operator Panel is a simple “Go/Stop” control screen designed especially for production floor personnel, and allows for easy operation. Audio Guidance augments the control screen display with spoken assistance, similar to a GPS navigation device. The Operation Chart panel gives operators a one-stop screen to teach the robot new settings such as positions/strokes, speeds, wait timers, etc, with no need to switch screens. Such innovations allow customers to operate the RC Series robots with ease and confidence. List prices for the new robots range from JPY 3,700,000 for the RCII-100S to JPY 6,100,000 for the RCII-400D model.  Yushin Precision expects to ship a combined 600 units approximately in the first year of production of these four models.
