Yushin developed side-entry type high-speed take-out robot

for clean molding environment.

Yushin Precision Equipment Co., Ltd.

Yushin developed "SXA-300 series", a side-entry type high-speed take-out robot for clean molding environment 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).

Now, molded products such as optical parts, food containers or medical equipment are produced in molding plants having clean environment or in low-ceiling clean rooms. "SXA-300 series" is suitable for these environments.

SXA-300 series is developed for molding machines whose clamping force is 180~450t and it extracts small-size molded products like a syringe, cup and so on.

As for this SXA-300 series, "SXA-300III/V" for two plates mold (*1) and "SXA-300III/X" for three plates (*2) mold are lined up. SXA-300III/V is for products take-out with 3-axis Numerical Control, traverse axis, kick axis and vertical axis. On the other hand, SXA-300III/X is under 5-axis Numerical Control, traverse and kick axes for runner take-out in addition to the three axes for SXA-300III/V.

Features of SXA-300 series

1. Side-entry enables this series robot to take-out with the shortest stroke by waiting for the mold open at the side of it. This series robot is designed to be not only having fewer dust generation but also applicable for low-ceiling plants as no driving mechanism is located above the mold.

2. Adoption of high-power motor enables this series robot to perform smooth high-speed operation with smooth acceleration and deceleration. Take-out dry cycle time (*3) is 0.65sec and full dry cycle time (*4) is 2.95sec.

3. This series robot is equipped with E-touch Web controller as standard.

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 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 and assist the operator or maintenance staff. 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)Two plates mold: The most popular type of mold used at the present This type of mold is composed of two plates, stationary one (cavity) and movable one (core).

(*2)Three plates mold: This type of mold is composed of three plates, two plates same as two plates mold's and runner stripper plate to remove runner from mold.

(*3)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.

(*4)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.
