Compared to a different take out system, six axis robots give us an option to even pack the bottle or bring it to a leak detection machine. Now we have dwell time at the robot,” said the plant manager. “Six axis robots give us the ability to look at secondary operations and an opportunity to potentially add some value to our customer’s process. We can present it to our customers as a benefit. Efficiency at the facility has been greatly affected by the addition of Robotic SUBTA units.
Motion Controls Robotics’ created the Robotic SUBTA system, a pre-engineered robotic system designed for PET blow-molded bottle handling. The system uses different robotic units depending on the type of machine that is being unloaded. The Robotic SUBTA system grabs and sets the bottles on a conveyor, standing up, acting as a takeaway unit. The system provides increased throughput due to high reliability and uptime and cycle times faster than most mold machine rates. The Robotic SUBTA system also requires a minimum of floor space, a high priced commodity in a manufacturing facility.
The Robotic SUBTA system is also flexible and precise since it handles any mold configuration (single or double row) and provides quick changeover using quick change tooling. This programmable built-in operator pendant has stored recipes and menu selection for patterns and allows for on-the-fly adjustments. The 20-part recipe keeps part data such as part description pick, place locations, and vacuum pattern.
The plastics manufacturer also considered a vendor with a fixed automation system that included a simple slide but decided that system wasnâ€™t reliable enough for its needs. In addition, every time the mold tooling changed, the slide also had to be changed to accommodate the new product. This created a higher cost to change tooling that was not acceptable. The facility included one machine with a manufacturers fixed automation system, but they wanted to find a more flexible and reliable solution.
