Purpose
A flexible feeder is an automatic orienting-and-feeding device. By means of controlled vibration it turns a pile of random parts into an orderly, correctly oriented stream that can be delivered to the next workstation or to an assembly machine. It is indispensable in battery, hardware, electronics, pharmaceutical, food, plastic-insert, sprayer, connector and many other industries.

Working Principle
The feeder exploits resonance and wave-interference effects. In Danikor’s flexible vibratory units four voice-coil motors (the “vibration sources”) are located at the four inner corners of the base. By driving these motors at or near the natural frequency of the parts, the bowl induces resonance, putting the parts into an “active” state in which they move easily and orient themselves.

Key Information Needed When Ordering

1. Actual part sample or drawing from production.

2. Required feed direction (vibration frequency).

3. Desired part state and output rate after vibration.

4. Space envelope, mounting position and available power supply.

Main Technical Specifications

• Rated supply: AC 220 V / 110 V, 20–65 Hz

• Model range: U10 → U60 (select according to part size)

• Motion modes: up-down, left-right, vertical dispersion, centre-accumulation

Installation & Routine Maintenance

1. Check that all fasteners on the drive base are tight.

2. When assembling, align the counterweights so that the upper and lower threaded holes match.

3. After setting height and levelling, bolt the lower base firmly to the stand or mounting plate.

Common Faults & Remedies

A. No vibration after power-on

• Blown fuse in controller

• Loose or damaged component

• Poor plug/socket contact

• Failed electrical part

B. Insufficient speed

1. Broken or loose spring plate (check elasticity screws).

2. Coil overheating or burn-out (check magnet temperature).

C. Feeder will not start

1. Supply voltage too low

2. Broken cable between bowl and controller

3. Controller fuse blown

4. Coil open-circuit

5. Bowl jammed against a hard object; top or bottom plate touching surrounding equipment

D. Weak or erratic vibration / irregular part flow

1. Base plate too thin

2. Mounting table lacks rigidity (minimum 1½" thick steel or aluminium recommended)

3. Table not level

4. Debris inside bowl

5. Machine cycle too fast – parts slip off track

6. Mains fluctuations

7. Controller needs retuning for current mains conditions

8. Part problems: out-of-tolerance, bent, oily

9. Loose or mis-aligned bowl-to-base screws

10. Overfilled bowl

11. Incorrect base tuning

12. Part change – bowl surface must be re-machined and base re-tuned

Keep this checklist handy; most issues can be resolved in minutes without special tools.
