What was the development concept behind the Take-out Robot?

Up until now, our key concept at Yushin has been "Heartful Technology." We put this to work in developing robots and systems that are more sophisticated and at the same time more user-friendly. For instance, in 1989, we were the first in the industry to use the servo motor that has now become the main means of drive for take-out robots. At that time, the servo motor itself was still very expensive, and manufacturers tended to consider it too sophisticated for their needs. At Yushin, however, we were not merely looking for a means of driving our take-out robots with servo power, but we were already looking ahead to a goal of complete automation in the molding plant. With that in mind, at the same time that we were working to develop our own proprietary motor drive technology. We were developing a take-out robot with full automatic control from the moment of startup where there would be no need to carry out manual position adjustments, and positions could be adjusted simply by pressing a certain key on the controller display screen. In addition, we were also building robots that could stock products in containers, pack products that were difficult to stock, and insert finely detailed pieces. We succeeded in making a significant contribution to total automation in processes subsequent to the take-out process and streamlining the work with reduced human labor.

Among plastic molded products, those with thinner constructions that are used in tableware and kitchen utensils, medical equipment, optical disks and other fields are mass produced. There is a strong call in these fields for higher production efficiency. For that reason, using part removal robots in molding processes to shorten total cycle times using higher-speed operation has become a primary focus of interest. A tiny difference of a fraction of a second in the cycle time can mean a huge difference in the overall productivity of the plant. Another demand is for machines that can repeat the same operation many thousands of times in succession without an error. The part removal robot is a dedicated machine that can meet these exacting demands continuously, at ultra-high speeds. With the explosive growth taking place in the information equipment market, a world record of 0.069 seconds has been achieved in the field of mass-produced CDs, DVDs, and other optical disks (by the ultra-high speed disk part removal robot DRDIII). That achievement has been highly acclaimed by the industry worldwide.
