When discussing the topic of equipment maintenance, vibratory feeders are systems that rarely need it. However, this doesn’t mean that they won’t break down at some point due to a problem. As they are automated, and rarely operated with the help of a user, sooner or later, these material handling systems are bound to malfunction/shut down. So we thought we would give you the lowdown about a few common problems associated with vibratory feeders.
Issues Pertaining to Vibratory Feeders
Generally, organizations that use these feeders will find four common problems to deal with. Let us take a look at them and their solutions.
Problem: Noise Emanating from the Feeder: This is possible due to a few reasons – Parts in the bowl are hitting against each other. The stand on which the feeder is placed is not stable enough. The fastener to the unit is not tight enough.
- You can reduce the number of parts in the bowl, or use a supply hopper.
- Brace the open space under the stand to strengthen the base. You can also just replace the stand.
- For the drive unit, disassemble the bowl from the unit. Clean all the surfaces and then reassemble the bowl.
Problem: Feeder Bowl Dead Spots: These are places within the bowl where a lag of activity is taking place, causing an imbalance. Other reasons for dead spots can be – a broken spring, or a cut or loose foot.
Solution: There are three ways to rebalance the feeder:
- Use counter weights to create the balance.
- Adjust the torque on the bottom end of the feeder’s springs.
- If the problem is quite drastic, then change the springs.
These are the first issues generally face by vibratory feeder operators. The remaining two will be discussed in the next post.
