Feeder Bowl Types

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.

Quality Feeder Bowl Construction

Attica Automation feeder bowls are constructed for long-term use in demanding production environments. Our feeder bowls are manufactured using 11 GA 300-Series Stainless Steel to provide a strong, durable bowl structure with excellent resistance to corrosion and everyday industrial use.

Built Around the Application

Material selection, tooling construction, wear surfaces, and feeder configuration are determined by the specific application. Part material, weight, geometry, production rate, orientation requirements, and expected wear are all considered when designing the feeder.

Quality construction, application-specific tooling, and attractive lead times help make Attica Automation feeder systems a practical solution for both new equipment and existing production lines. Our goal is to build a feeder that not only feeds the part correctly, but is constructed to withstand the demands of the production environment.

Screw Feeder Bowls

Screw Feeder Bowls are designed for parts with a defined head, flange, shoulder, or similar feature with a shank extending from it.

Typical parts include: Screws, bolts, studs, rivets, pins, threaded fasteners, flanged components, double-ended fasteners, and similar headed-and-shank components.

Available Screw Feeder Bowl Sizes: 15" | 24" | 30" | 36" | 42"
Available in Clockwise and Counter-Clockwise Rotation

For parts with simple geometry and favorable feeding characteristics, feed rates can reach 800+ Parts/Minute. Screw Feeder Bowls are not limited to simple parts. Custom tooling and orientation features can be incorporated to accommodate difficult part geometries, challenging centers of gravity, and more complex orientation requirements.

Custom Feeder Bowls

When a standard Screw Feeder or Washer Feeder is not the right solution, Attica Automation can design a Custom Feeder around the specific part and production requirements.

Available Custom Feeder Bowl Sizes: 6" | 8" | 10" | 12" | 15" | 18" | 21" | 24" | 27" | 30" | 36" | 42"

Every Custom Feeder is developed around the requirements of the individual application rather than a predetermined part-size range.

Custom Part Orientation Tooling

Custom Part Orientation Tooling is available for parts that require additional control or orientation before entering the final feeder tooling.

• Custom Flip Tooling
• Bolt-In Tooling
• Head-Heavy Part Orientation
• Part Flipping or Repositioning
• Orientation of Double-Ended Parts
• Controlled Transitions into Final Tooling
• Custom Guides and Selectors
• Application-Specific Orientation Features

Bolt-In Tooling

Bolt-In Tooling can provide a removable or replaceable tooling solution for applications where different tooling configurations may be required. Depending on the application, bolt-in tooling can make future modification, replacement, maintenance, or retooling easier without requiring permanent changes to the entire feeder bowl.

Custom orientation tooling can be incorporated into a new feeder or, when practical, integrated into an existing feeder system.

Feeder Bowl Retooling

Existing feeder bowls can often be modified rather than replaced.

Each existing feeder is evaluated individually to determine whether retooling is practical for the new application.

Complete Feeder Refurbishing

Full feeder refurbishing is available for existing systems. Depending on the condition of the equipment, refurbishing may include bowl restoration, tooling repair, tooling modification, drive restoration, replacement of worn components, cleaning, feed adjustments, and updated mounting components.

Refurbishing can be a cost-effective option for extending the usable life of an existing feeder system.

Coatings

Urethane lining is available to help protect both the feeder bowl and the parts being handled.

Our standard urethane option includes urethane applied to the bottom of the feeder bowl and the bottom of the return pan. Urethane can also be applied up the feeder track when additional wear protection or part protection is needed.

• Protects the Feeder Bowl from Abrasion — Helps reduce wear on the bowl bottom and other high-contact areas.
• Helps Prevent Bowl Damage — Reduces impact on the bowl bottom, helping protect against deformation, cracking, and premature wear.
• Protects Parts from Damage — Provides a softer contact surface when parts are dumped into the bowl, helping reduce scratching, denting, and other impact-related damage.
• Reduces Noise — Helps absorb part impact and vibration, making the feeder bowl quieter during operation.
• Improves Traction — Urethane can help reduce slippage caused by oil or other surface conditions, improving part movement through the feeder.
• Helps Defeat Hydrostatic Tension — Urethane lining can help reduce sticking or holding effects caused by liquid films between the part and bowl surface.
• Extends Usable Bowl Life — By reducing impact, abrasion, and wear on the feeder bowl, urethane can help extend the usable life of the system.
• Urethane Track Lining Available — For applications requiring additional protection, urethane can also be applied up the feeder track to help protect both the parts and feeder tooling.

Standard urethane coverage includes the bowl bottom and return pan bottom, with additional track coverage available based on the application.

Feeder Mounting & Vibration Isolation

Feeder systems are available with thick, oversized rubber feet designed to improve vibration isolation.

3-way adjustable foot cups provide additional adjustment during installation and make feeder positioning and alignment easier.

Feeder Components & Automation Products

Attica Automation distributes a variety of components used in vibratory feeding, part handling, sensing, and automation applications.

Components can be supplied for new equipment, replacement parts, system upgrades, and existing feeder applications.

Air Jet Systems

Air jets are available for feeder bowl tooling and other automation applications where controlled air is used to assist with part orientation, rejection, separation, or movement.

The clamp and Air Jet Tab style design allows the air jet to be positioned and adjusted based on the requirements of the application. Air jet systems can be incorporated into new feeder systems or supplied as individual components for existing equipment.

Various air jet sizes, fittings, manifolds, hoses, and mounting components are available to suit the requirements of the application.
