Q: What are the pros and cons of multiple part feeders?

A: Multiple Part Feeding for Automated Systems

Are you asking can our part 'family' be fed in a single feeding system? Excellent question. The answer is, it all depends. The variables to consider are:

1) Are the parts to be fed similar in size or shape?
2) Can our machine operators make setup adjustments in tooling and when necessary, air assist settings?
3) Have we accurately communicated our production objectives to our feed system supplier? (for example, do we change over after running 50 assemblies or 500?)
4) Do we have the volume to justify a feed system dedicated to each part?

Your final decision should be based on a review of these variables. Discuss them with your feed system supplier. Your specific requirements should be weighed against the positive and negative aspects of a multiple part feeding system. If it is decided that a single vibratory feeder can handle your parts, make sure to stipulate a few common sense guidelines for the design and fabrication of your system.

A must have is a "Feeder Directive" which gives clear written instructions on the settings and adjustments for each part change. Another reasonable request would be that where adjustments are necessary, have your supplier incorporate definite 'stops' for each setup, so that even someone inexperienced can easily and accurately change from part to part.

Finally, in using a multiple part feeding system, it would be well worth the expense involved (if any) in a training session to familiarize your operators in the efficient operation of your new feeding system.
