Yushin commercialized high-speed take-out robot

for large-size molding machine.

Yushin Precision Equipment Co., Ltd.

Yushin commercialized "RAII- a -1300S-HS" as a new type of WEBLINER "RA/RAII- a -HS series" and started to receive orders by customers on September 24th when Yushin exhibited one at IPF2005 venue, Makuhari messe.

Yushin is the dedicated supplier of take-out robots for injection molding machines, carrying the motto "Heartful Technology"(President Mayumi Kotani, headquarters in Kyoto City, capital of 1.98566 billion yen).

RAII- a -1300S-HS, whose target clamping force is 1000~1600t, was developed for extraction of large-size molded products such as automobile-related products, home-electric appliances, housing-related products and so on. And it can be installed in low-ceiling palnts by featuring 2-stage telescopic arm for shortening the robot's overall height.

The RAII- a -1300S-HS demonstrates its prepotency in high value-added production by offering increased rigidity of the robot frame to ensure smooth linkage to downstream processes that require a high degree of positioning accuracy, as well as high speed operation that effectively helps to shorten molding cycles. Especially it targets on shortening take-out time as a direct contribution to production efficiency. Users can choose according to objective between a high cycle type that comes standard with high power servo motors on both kick and vertical drive axes, and an optional 3-axis high cycle type that adds a horizontal traverse axis.

The high cycle type delivers a take-out dry cycle time (*1) of 1.30 sec and a full dry cycle time (*2) of 11.75 sec, whereas the 3-axis high cycle type cuts total dry cycle time to 8.80 sec.

In comparison with "VNII- a -1300S-HS", the former type of high-speed take-out robot, it cuts 17.2% take-out dry cycle time and 5.3% full dry cycle time. And 3-axis type cuts 14.1% full dry cycle time.

This robot is equipped with E-touch Web controller as standard. This controller is designed and built for exchanging production information over the Internet or a LAN, as well as for managing production from a remote location. Even with the former NETLINER series, production management by networking the take-out robots through LAN was already established, but it kept developed and now managing production from a remote location over the Internet is granted to be important for efficient management.

The E-touch Web controller has following features.

1. Equipped with the communication port necessary for networking. 2. Flexible and expandable functions realized by Windows-based operation.

(1)Data transmission via network

By connecting the robots to an in plant network, the operator can copy and send teaching data directly to any similar robot in the network. Messaging functions allows sending of data or information to any similar robot or office computer on the network.

(2)Remote control

If remote control software is installed on the robot controller, teaching data and programs can be transferred and updated over the internet. This is an expandable function that allows future Yushin service center to support customers recover from difficulties by checking programs or offering other services.

(3)Note function

Using the supplied stylus, operators can note down on the controller. Operators can also import images of molded products with an optional USB camera, and make notes and add comments on them and store them with the teaching data.

(4)Camera phone

If a USB camera is connected to the controller, the operator can have a net meeting with any other remote person in management office with a PC. The remote person can see conditions of molded products or condition of defect. As well as Remote control function, this is an expandable function that allows future Yushin service center to support customers recover from difficulties by talking on the phone or offering other services.

3. Equipped with software "Lead Through Teaching" that allows customers to easily add and modify robot motion programs.

(*1)Take-out dry cycle time: It is the cycle time required to simulate a part extraction operation with a robot simple substance. More precisely, the simulated operation includes only extraction motion from inserting a robot arm into molds to taking out products from the molds. Stroke and timer used as the basis of dry-cycle calculation are based on a standard specified by Yushin.

(*2)Full dry cycle time: It is the cycle time required to simulate the whole extraction operation with a robot simple substance. The whole operation means a series of motions such as extraction motion from standby position, product release motion at a predetermined position and return motion to the standby position. Stroke and timer used as the basis of dry-cycle calculation are based on a standard specified by Yushin.
