Bowl Feeder for Rubber Rings with Oil/ Rubber Ring Feeder

What to Do If Oily Rubber Products Stick to the Vibratory Bowl? Solutions?

1. Root Cause Analysis

1. Oily Surface: The oil film increases adhesion to the metal track.
2. Rubber Material: Soft, high friction, and prone to static buildup.
3. Insufficient Vibration Force: The bowl’s vibration cannot overcome adhesion and static.

1. Systematic Solutions
2. Preferred Solution: Change the Feeding Method
   For oily rubber parts, consider alternatives:

• Pusher Feeder: Reliable, mechanical pushing eliminates vibration dependence.
• 遠心フィーダー: Uses gentler, rotational action.
• Flexible Feeder with Vision: Parts are scattered and robot-picked, avoiding sticking.

2. If a Vibratory Bowl Must Be Used, Implement Extreme Measures:
3. Surface Treatment & Modification (Most Critical)

• Teflon/PTFE Coating: Apply a thick, wear-resistant non-stick coating to the track. This is mandatory.
• Use Low-Surface-Energy Materials: Consider UHMWPE for track sections.

1. Vibration & Mechanical Adjustment

• Maximize Vibration Energy: Increase amplitude as much as possible without part scattering.
• Optimize Vibration Angle: Fine-tune the leaf spring attack angle for effective part “peeling.”
• Maintain Very Low Part Level: Prevent excess pressure and oil accumulation.

1. Active Cleaning & Assisted Separation

• Install Air Blow-Off System: Use precise compressed air jets at key points to blow parts free.
• Add Pre-Cleaning Stage: Clean parts before feeding to remove excess oil.
• Mandatory Static Elimination: Use an ionizing blower directed at the track.

1. Environment & Maintenance

• Scheduled Deep Cleaning: Clean the bowl regularly with compatible solvents.
• Control Ambient Temperature: Avoid high temperatures that make oil more fluid.

Final Recommendation: For oily rubber parts, first evaluate non-vibratory alternatives like pusher feeders. If a vibratory bowl must be used, a combination of Teflon coating, strong air blow-off, static elimination, and low part level is essential, along with readiness for high-frequency maintenance.
