Case Study
Vibratory Rivet Feeding System with Predefined Footprint
Bellco engineered a high-speed rivet feeding system to meet tight spatial constraints and deliver precise, reliable performance for a manufacturing company.
The Challenge
A manufacturing company came to Bellco with a complex parts feeding challenge: deliver four rounded-head rivets every three seconds, and integrate the system with their existing press. Our team engineered a dual-system multi-lane vibratory feeding solution to align seamlessly with the customer’s existing press setup, despite tight spatial constraints and demanding part geometry.
Feeding Rounded Rivets into a Press Bed with No Clearance
The feeding system needed to fit perfectly within a predefined footprint, align exactly with height requirements (nothing could protrude above the press bed, or it risked damage), and deliver rivets every 3 seconds.
Compounding the challenge, the rivets had rounded heads that did not allow them to sit flat. This required a custom linear track with a precise shape to keep the rivets from rocking and tilting.
The Solution
Bellco provided
⚙️ Multi-Lane vibratory feeder system designed within specific spatial requirements
Full CAD models for review and approval
🎨 Custom-painted components to match customer specifications
🎥 High-quality video of the final system for final approval and documentation
A Fully Integrated, High-Precision Feeding System
Our team collaborated closely with the customer to design a vibratory rivet feeding system consisting of:
- 2 custom vibratory bowl feeders, each with 2 tracks, mounted on either side of the existing press
- 4 escapements, (2 per system), delivering rivets every 3 seconds to exact locations on the press
- A custom-shaped linear track profile, to stabilize the rivet’s rounded head and ensure reliable orientation and movement
- A layout that adhered strictly to the press bed height restrictions, allowing seamless integration
All design work was completed in SolidWorks 3D CAD, providing the customer with full model access to review and verify integration with their existing system before manufacturing began.
- SolidWorks 3D CAD file for customer approval.
- SolidWorks 3D CAD file of custom escapement.
- SolidWorks 3D CAD file of second custom escapement.
Performance & Results
Performance & Results
Complete vibratory bowl feeder system with linear track.
Vibratory bowl feeder for round-headed rivets.
Custom escapement delivering rivets to exact location on the existing press.
Custom escapement delivering rivets to exact location on the existing press.
Each system delivered a total of 40 parts per minute (20 PPM per lane), meeting the required production cycle time while maintaining exceptional accuracy. Escapement was tested in fully automatic mode to validate consistent part delivery and alignment with the press.
