Systems for automatic tightening (blowing systems) – ASG, AIV, AOV Series

Automatic blow-feed screwdriving systems are the ideal solution for productivity, speed and process continuity: in this technology, the screw is transported by compressed air directly from the feeding system to the screwdriving module, arriving already oriented and ready to be tightened.

The range of blowing systems for tightening includes two different solutions:

  • The ASG series is the ideal standard module for applications requiring free access and favourable screw geometries. In this case, the screw is fed and guided to the clamping jaws, where it is held in place and immediately tightened, ensuring stability and speed.
  • When conditions become more complex, systems with integrated suction come into play: the AIV-AT series, designed for screws with an internal drive, and the AOV series for screws with an external drive, combine blowing with vacuum to stabilise the screw throughout all stages of the process. This allows for much more precise control, particularly where access is difficult or quality requirements are high.

The system always works in combination with a feeding unit, which has the task of selecting, orient and supply the screws in a continuous manner.

  • Feeder series FBH, based on vibration;
  • “Step” feeder FLH series, which uses a “step” motion instead of continuous vibration.

Automatic tightening systems (blowing type) are the ideal solution for productivity, speed and process continuity

The principle of operation of the screwdriving systems using air is extremely linear, but at the same time highly optimised.

The screw is first selected and aligned by the screw feeder, then propelled by compressed air along a tube to the screwdriving module. Here, it is held in place, correctly positioned and tightened automatically.

  • In standard systems (ASG series), the screw is guided by the clamping jaws, which ensure its stability until it is tightened.
  • In more advanced systems, however, vacuum technology is also employed (AIV series for screws with an internal drive, AOV series for screws with an external drive): the screw is actively ‘gripped’ and controlled, enabling the system to verify its presence and correct position before proceeding. This introduces a further level of safety and quality control into the process.

Il principale vantaggio di questa tecnologia è la velocità: il ciclo è estremamente rapido e continuo, rendendo il soffiaggio la scelta preferenziale per produzioni ad alto volume.

However, in order to function correctly, it requires favourable operating conditions, in particular:

  • a compatible geometry of the screw;
  • enough space around the screw point.

Every application is different. And precisely for this reason there are no “standard” “standard” when we talk about automatic screwdriving.

Screw type, available space, accessibility, required productivity: every module, feeder and accessory is combined to create a truly effective solution.
