Forget the vibrating trough..it ain't gonna work.
What you need are a set of ROLLER Feeders. Two long straight hardened steeel
rollers with belt or friction drive arranged to couter-rotate them up and away
from each other..if you catch my drift. In other words, vieved from the end,
the LH roller should rotate CCWa nd the RH roller should rotate CW. The feed
will be along the trough or vee formed between the rollers and direction of feed
and spped will be determined by the decline of the roller axes from horizontal.
These can be made from Thompson hardened shafting, driven by a FHP motor and
will feed at phenomenal rates..fast enough to shoot the wires full length of the
stack at the end.
Vibratory trough feeders tend to jam and balk, especially with less than
perfectly straight or smooth ended parts. They also loos the feeding "Oomph" as
soon as the part starts to leave the trough. Noisy buggers too!
Parts feeding guru!!
