Yushin Automation have extended the range of high speed robots primarily used in the packaging industry with the expansion of the HST range. The Yushin HST-600 robot joins the range which starts with the HST-150 and will run at high speed on machines ranging from 500-850tons. The HST range of robots can achieve take out times of 0.35 seconds and an overall cycle time of 4.5 seconds, making it suitable for most packaging applications which can include secondary functions including in mould labeling.
The key to high speeds is the revolutionary form of Computer Aided Engineering (CAE) that Yushin had been perfecting for high performance tool design alongside Kyoto University, CAE application is able to seek out the theoretical optimum form for a device and it led to three key areas for change and improvement:
In numerous areas we discovered new ways to create moving components and supporting architecture that allowed us to considerably reduce unnecessary weight while maintaining the same rigidity. We found a 13% reduction in the weight of the machine, most importantly on the moving parts allowing for high speeds with smaller motors giving a greater energy reduction and lower running costs.
The wrist area of the robot lies at the extremity of the arm and must enter the mould during take out. Any bulk removed here allows the mould opening to be reduced, saving valuable time on each cycle. We managed to create a comparable wrist that is an incredible 38% slimmer, allowing mould openings to be a vital 41mm narrower over a standard robot.
Vibration is a particular hindrance to high speed operation because time delays must be programmed in to allow settlement. Our engineers designed a radically new Vibration Control Technology and also created a new carbon fiber reinforced plastic arm that promotes superior vibration dampening.
We have also included our groundbreaking ECO vacuum system which reduces air consumption by up to 75% over the previous model, even better we now can monitor the energy use and air consumption in real time.
