Feeder Bowl Types

Automatic Part Feeding & Orientation

What Are Vibratory Feeder Bowls?

Vibratory Feeder Bowls are automated part-feeding systems designed to separate, orient, and deliver bulk parts in a consistent position to downstream equipment. Parts are placed into the feeder bowl in bulk. Through controlled vibration and custom tooling, the parts travel around the bowl where they are sorted and oriented before being discharged in the correct position.

Typical Parts

  • Screws
  • Bolts
  • Studs
  • Washers
  • Pins
  • Rivets
  • Stampings
  • Plastic Components
  • Machined Components
  • Custom Parts

Benefits of Vibratory Feeder Bowls

  • Consistent Part Orientation
  • High Feed Rates

Attica Screw Feeder Design Advantage

Open Tooling, Full Shank Support & Fast Part Changeovers

Designed for higher feed rates, better part control, fewer jams, and fast adjustment between part sizes.

Developed from 50 years of bowl-building experience. Attica Automation’s screw feeder design was developed by our senior bowl builder, drawing on 50 years of experience building and refining vibratory feeder bowls for demanding production applications.

Attica Automation screw feeders use an open tooling design that provides easy visual access to the feeding and orientation tooling from virtually any direction. This makes the feeder easier to inspect, adjust, troubleshoot, and modify without unnecessarily obstructing access to the tooling.

Our design keeps the part shank supported all the way to the discharge, providing better control of the part throughout the feeding process and helping eliminate criss-cross jams that can occur when parts lose support or overlap.

  • Open Tooling Design — Easy visual and physical access to tooling from virtually any direction.
  • Shank Supported to Discharge — Maintains control of the part through the full feed path and helps eliminate criss-cross jams.
  • Higher Feed Rates — Our screw feeder design has been proven in production applications to outperform other designs with higher achievable feed rates.
  • Less Jamming — Improved part control helps reduce interruptions and maintain consistent feeding.
  • Fast Part-Size Adjustments — Adjustments for a part change can typically be completed in only a couple of minutes.
  • One Tool for All Adjustments — Simplifies setup and reduces the time required to make feeder adjustments.
  • Quick Application-Specific Modifications — The open design makes it faster and easier to modify tooling for unique or difficult parts.

Designed for fast setup and production: The combination of open access, continuous shank support, simple adjustment points, and one-tool adjustment helps reduce setup time while improving feeding consistency and overall performance.

New Washer Feeder Innovation

Precision High-Speed Orientation for Beveled & Crowned Washers

An innovative solution to achieve high feed rates of properly oriented washers.

Attica Automation’s new washer feeder design provides an innovative solution for applications requiring high feed rates with consistent washer orientation.

The feeder can identify and orient washers based on even the smallest bevels, crowns, or subtle differences between the two sides of the washer. Custom orientation tooling uses these features to ensure the washer is discharged in the correct position, with the beveled or crowned side consistently facing up.

This allows manufacturers to maintain proper washer orientation without sacrificing production speed.

  • High-Speed Washer Feeding
  • Consistent Bevel-Up or Crown-Up Orientation
  • Can Orient From Very Small Bevel Differences
  • Reliable Orientation of Similar-Looking Washer Sides
  • Reduced Incorrectly Oriented Parts
  • Designed for High-Volume Production
  • Custom Tooling Based on the Specific Washer Geometry

Precision Orientation at High Feed Rates: Even when the difference between the two sides of a washer is minimal, the feeder can be tooled around those small geometric features to provide reliable orientation and repeatable delivery to downstream equipment.
