Vibratory Bowl with Sound Enclosure/Sanki Feeder Bowl

How to Adjust a Vibratory Bowl?

Tuning a bowl involves balancing amplitude and frequency for optimal part flow. Always disconnect power before initial inspection.

1. Preliminary Inspection

1. Safety: Ensure power is OFF.
2. Check Fasteners: Tighten all bolts.
3. Check Air Gap: Ensure the electromagnet gap is clear and within specification.

1. Core Adjustment Steps
2. Adjusting the Leaf Springs

• Goal: Change the vibration angle and force.
  • Quantity: Adding springs reduces amplitude (gentler feed); removing springs increases it (more forceful).
  • Angle: Fine-tune the spring pack’s attack angle for precise control.

2. Adjusting the Controller

• Goal: Change vibration strength and rhythm.
  • Amplitude Knob: Adjusts voltage. Clockwise increases amplitude; counterclockwise decreases it.
  • Frequency Knob (if available): Adjusts the on/off frequency of the electromagnet.

III. Testing and Optimization

1. Load Parts: Add a small sample of parts.
2. Power On: Start with low amplitude.
3. Observe and Tune:
   • If parts don’t move: Slowly increase amplitude.
   • If parts bounce or stand up: Decrease amplitude.
   • For jams: Inspect and adjust local track tooling or vibration.
4. Full Load Test: Gradually increase parts to normal level to ensure stability.

Summary: The golden rule is “start low and adjust incrementally.” Success is achieved when parts flow steadily, continuously, and controllably without bouncing, backflow, or piling up.
