ASG Automatic Screw Feeder System

Auto Feed System

The ASG Automatic Screw Feeder System (Auto Feed System) is designed to increase production while decreasing cycle time and labor costs. This is accomplished through attributes that provide for speed, reliability, and use of maintenance. In regards to speed, the system is very swift, delivering a screw to the jaw set in less than half a second. Because of its simplistic design, the Automatic Screw Feeder System is also reliable and consistent, providing for virtually jam-free operation. Finally, the Automatic Screw Feeder System has multiple access panels that may be removed without tools, to provide for ease of maintenance.

ASG offers two types of systems – a Manual and an Integrated Automatic Screw Feeder System.

The Manual Automatic Screw Feeder System has two stroke mechanisms: the forward bit stroke and the telescopic stroke.

The Manual Automatic Screw Feeder consists of four main components:

  •  – Vibratory Bowl Feeder
  •  – Stroke Mechanism: Forward bit stroke or telescoping
  •  – Customizable nose piece
  •  – Customizable jaw set

The Integrated Automatic Screw Feeder consists of four main components:

  •  – Vibratory Bowl Feeder
  •  – Fastening Slide
  •  – Customizable nose piece
  •  – Customizable jaw set

The Automatic Screw Feeder System is capable of feeding and fastening various types of screws (metric, self-threading, self-tapping, etc.) with various types of head (countersunk, flat, oval, etc.) and various types of imprint (slotted, cross-slotted, etc.).


In the automatic screw feeder machine, the vibratory bowl precisely aligns the screws and presents them to the screw selector. Wherein, they are rapidly dispensed into the distribution tube. Finally, a blast of air propels the screw past the screw sensor into the jaw set.

The PLC, signaled by the screw sensor, initiates the driving sequence.

Dependable screw feeding is managed by the PLC to optimize all machine parameters.

The nose piece holds the screw blown from the bowl feeder and guides it toward the work piece, enabling the bit to engage the screw and fasten the components.

Allows excellent axial compensation.

Accurate screw guide to fastening location.

Capable of attaining various depths.

Customizable for space constraint dependent on application.

Compact in size and provides screw tip visibility.

Quick and easy to assemble and disassemble.

Bit engages the fastener, eliminating the fastener pushing back into the jaw set.

Manual Automatic Screw Feeder with forward bit stroke

  • Patented Forward Bit Stroke.
  • Tip of the screw is visible in order to assist the operator.
  • Forward stroke automatically retracts the bit, therefore minimizing surface damage.
  • Increased fastening process: screw tip is visible to the operator, which eases centering on the screw hole, streamlining process time and safety.
  • Long bit stroke: allows reaching tightening points with difficult access (such as close to sidewalls) or narrow recesses.
  • Nose Piece Rotation: 360° in 60° increments.
  • Nose Piece Quick Release System: quick and safe bit replacement.

Manual Automatic Screw Feeder with telescopic device

Equipped with telescopic device to work with high speed and optimum grip at different depths or inside the holes.

Screw shooting sensor: Aside from offering reliable tightenings and continuous working cycles with minimal screw jams, the version with 2 sensors controls the final screw height.

All models are equipped with a nozzle allowing practical rotation of the head in 6 positions at 360°. Thus, the position of the head can be adjusted based on the encumbrances of assembled workpiece.

Integrated Automatic Screw Feeder System

Integrated Automatic Screw Feeder System Details

The ASG Integrated Automatic Screw Feeder System consists of two main components – the vibratory bowl feeder and the fastening slide – as well as a customizable nose piece and jaw set. This automatic screw feeder is designed to be integrated into assembly systems and robots.


Engineered for proper movement, the fastening slide ensures a proper stroke approach of the motor/screw to the component to be tightened. This provides high quality fastening of the assembled product to ensure all screws are properly fastened. Manufactured with aluminum alloy, the fastening slide is light and compact (as narrow as 40mm in width) and can be used on solutions with manipulators or robots and supports axial thrust (for example with self-drilling screws).

  •  – Includes a support structure, pneumatic cylinders, and driver.
  •  – The steel backbone structure allows for the unit to be mounted to robotic arms or manipulators; while the pneumatic cylinder(s) provide the force to accurately drive the fastener into the part.
  •  – The driver can be pneumatic or electric. The X-PAQ™ SD2500 (DC Electric) tool is recommended to maintain precision within the system.
  •  – Manages the working cycle and guarantees high flexibility, by allowing changes to be made to the tightening cycle based on the specific application.
  •  – Ideal for manipulators, robots and anthropomorphic arms.
  •  – For air nutrunner motors: ø max 36 mm.
  •  – For electric nutrunner motors: ø max 42.5 mm.
