FIPA Inc., a manufacturer of advanced vacuum technology, gripper systems, air nippers, tube lifters, and End-of-Arm-Tooling (EOAT), announces its efficient, air- and energy-saving EMA Series compact ejector. Suitable for use in pick-and-place packaging technology, as well as in various applications throughout the plastics, automotive, packaging, and sheet metal forming industries, EMA Series compact ejectors combine a pressure regulating, energy-saving function with an electronic air-saving function to achieve operational savings of up to 97% when handling non-porous, light- to medium-weight workpieces.
The series also combines electronic vacuum and blow-off control functions in a single signal to achieve short cycle times, and features an integrated open silencer for noise reduction, and a compact, IP65 dust-resistant block construction that both negates the need for additional filtration and enables space-saving assemblies.
EMA Series ejectors were designed to provide maximum energy savings without limiting the overall performance of production systems. They operate by supplying a Venturi nozzle with compressed air to generate a vacuum, which allows an attached suction cup to quickly grip the workpiece. A vacuum switch continually monitors the vacuum level to control air savings, and triggers the “item gripped” signal at the first vacuum threshold limit (V1, 65%), allowing the scheduled operation (e.g., item transfer or processing) to take place. When the vacuum reaches the second threshold limit (V2, 75%), the ejector interrupts the compressed air supply to the Venturi nozzle, reducing energy consumption to zero. The remaining vacuum, enabled by a closed, non-return valve, continues to reliably grip the workpiece without any additional energy expenditure until minimal, naturally occurring leakage eventually drops the vacuum threshold back to 65%, at which point the air-saving control cycle briefly generates a new vacuum until the 75% threshold is again achieved. Once the scheduled operation has been completed, the ejector’s blow-off valve generates an air jet that users can manually adjust the pressure of to quickly release workpieces.
The EMA Series’ energy-saving capabilities increase in conjunction with the difference between supply pressure and operating pressure. As such, EMA Series compact ejectors can achieve up to 75% energy savings during product transfer and up to 97% energy savings while holding non-porous, light- to medium-weight products for further processing. EMA Series ejectors can also achieve up to 90% energy savings while handling dense workpieces, and up to 50% energy savings while handling porous items.
EMA Series compact ejectors are rated for 24VDC adjusted control voltage ±10%, and operating temperatures spanning 10 – 60°C (50 – 140°F). Feed pressure for the series spans 58 – 116psi.
