Electromagnetic
vibrating feeder is a system used since many years in
various sectors of the market and consists of a technology
for orienting and positioning many pieces. It can be
used when an automatic or semi-automatic processing is
required.
The vibrating feeder has a base on which it is fixed – by
means of proper supports – an electromagnet and an upper
part fir for containing or running the pieces. The two
parts (basement and upper part) are connected by means
of leaf-springs made in various material in accordance
with the type of vibrating feeder and with specific requirements.
There are two types of vibrators, with the same operating
system, but different type of vibration:
circular vibrators: for orienting and positioning
pieces. The dimension permits different autonomy.
They produce a circular vibration: clockwise or anticlockwise.
They are assembled with a bowl that can be: cylindrical,
step-shaped or conical.
linear (horizontal) vibrators: they produce
a straight-line vibration; assembled with a storage
hopper has the purpose of feeding the circular vibrator;
assembled to a conveying tough has the purpose to
transfer the positioned pieces to the engine. In
this case the linear vibrator is helpful when a photocell
is required.
The voltage supply is 230 V/50 Hz single phase. Different
voltage and/or frequency on request. The bowl could be
made in normal or stainless steel. On request different
bowls and special dimension according to the type of pieces
to be positioned.
Special coatings for the bowl It is possible to apply
special coatings directly in contact with the pieces to
move or position. The purposes of the coatings are:
to reduce the noise of the vibrating feeder;
to increase the feeding capacity in case of pieces
which are not in optimum conditions, such as damp or
oily pieces;
to reduce wear of the parts in touch with the pieces;
to reduce and/or avoid the possibility to damage
the surface of the pieces to move and position.
