Automatic screwing unit MCA EasyDriver EDS

for screw assemblyelectricpneumatic

Tightening unit with automatic screw feeding and fastening slide. Designed for high production rates, precision and reliability. Entirely designed and built by Fiam in Italy.

KEY BENEFITS
• Ideal for assembly of large series of identical screws
• Plug & Play solution, ready to integrate into assembly lines, manipulators, Cartesian axes, robots and cobots
• Interfaces with production management systems (Industry 4.0)
• Turnkey system with strict internal pre delivery tests

The unit consists of:

SCREWS FEEDER:
ED S – Silent Feeder has a segment conveyor inside the tank that loads, aligns and sends the screws to an inclined accumulator, exploiting the principle of gravity. The absence of vibration therefore guarantees maximum silence as well as preserving the characteristics of the screws and ensuring high quality assembly.
For screws L max 25 mm — tank capacity 2 litres
Has integrated:
 Portable PLC, extremely convenient for remotely managing tightening cycles.
 Connectivity: Fieldbus export (PROFINET / MODBUS TCP / ETHERNET/IP)
 Real time statistics and ability to set main machine parameters remotely; interface provided in English with dynamic flowcharts and graphs
 EDMI (EasyDriver Machine Interface): web server interface in the feeder for remote connection via PC, smartphone or tablet
• Over load sensor to ensure correct screw quantity on linear rail
• High speed screw selector/denester for closed chamber feeding
• Pneumo electric components (Festo)
• Low level sensor to indicate bowl reloading
• Analog line pressure switch to monitor incoming air pressure
• Stainless steel structure with transparent cover and removable side panels for maintenance
• Integrated filter, regulator and lubricator with gauge; tube bundle for hoses and cables: 5 m

NUTRUNNER MOTOR:
Can be pneumatic or electric, for any need for torque, speed and type of monitoring, with torque or torque/angle/time control as well as programming, analysis, of the tightening cycle with important advantages in precision and operational flexibility

FASTENING SLIDE:
Reliable at high cycle rates and where high axial thrust is required. In addition to the motor tightening stroke, the slide can provides an approach stroke to bring the head down to the component.
• Equipped with screw transit sensor and limit switch position sensors
• Compact size and low weight — suitable for manipulators and cobots
• “Screw at sight” function available on request to facilitate entry before approach
• Compact or bottom to top versions available on request for reduced clearances
• Offset devices available to reach tightening points with ~20 mm centre to centre distance

SCREW RETAINING HEAD
• Customised to the screw and component to reach required depths
• Reduced dimensions; special materials/supports can be used to avoid damaging components
• Mechanical retention (not vacuum) ensures reliable screw hold and prevents jamming in dusty environments and without risk of screws loss inside components thanks to mechanical screw retention

The system provides a perfect automatic approach stroke to the part being assembled and tightening cycle is managed by integrated PLC which relates to factory systems (Industry 4.0) and can be managed remotely. It interacts with various devices i.e Bar code reader, conveyor belt, workpiece clamping jig activation/deactivation systems, signalling and monitoring mechanism such as LEDs, part counters, light towers.
The ED S – Silent Feeder screw feeder can be combined with the DUST CLEANER screw cleaning device: an additional accessory available on request, essential for removing dust and fine particles from screws in automatic tightening systems. When correctly positioned in the production layout, it can speed up screw feeding times to as little as 0.3 seconds.
