The Model SD-185 Screwdriver head is equipped with placement jaws and a feed tube attachment. The feed tube conveys the fasteners from a vibratory feeder bowl to the placement jaws. A wide range of fastener types can be fed and driven by this screwdriver and the size of the feeder bowl is determined by the physical size of the chosen fastener. Fasteners can be driven into a workpiece to either a predetermined torque setting or to a specific depth setting. The screwdriver head has built-in sensing to confirm proper insertion of each fastener. This screwdriver may be purchased as a complete tooled system with controls and vibratory feed system.

The plastics manufacturer had used its manual take out system for its entire history for nearly 20 years. This manual system had several pitfalls including a large amount of scrap, which in turn meant money down the drain in throwaway products. The manual system also lacked reliability and increased chances for injuries. The company brought technology into its facility to help increase the production of quality products while making the plant safer for its employees. The company also hoped to increase its sales by improving the manufacturing process efficiencies through automation. Prior to automation, the company had to turn away opportunities to increase its business due to capacity limitations.
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.
It combines the automatic feeder with the automatically moving electric screwdriver to realize the complementary supply of screws and the locking, which greatly improves the production efficiency and saves manpower. Once the screwdriver is lifted after locking the screw, the automatic feeder will send the other screw to the Escape of the automatic feeder. The screwdriver head absorbs the screw and the robot can automatically move according to the coordinate point and tighten it. This is particularly suitable for multi-station workpieces of the same specification.  

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.
The plastics manufacturer also considered a vendor with a fixed automation system that included a simple slide but decided that system wasn’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.
