Product Feeder
The Model VF100e includes a vibratory Product Feeder used to move product from the hop-
per to the container. The Feeder consists of a Trough and Trough Bracket coupled by leaf
springs to an electromagnetic drive. Components of the Product Feeders are shown in
Figure 5.

During operation, the electromagnetic drive produces a vibrating stroke on the surface of the
feeder trough. The stroke is generated by the electromagnet pulling the trough sharply down
and back and then allowing it
to
spring up and forward. Repeated at high speeds (3600
v.p.m. at 60 cycle power supply), this action produces the vibrating movement on the trough
surface to move product.
The unit is mechanically adjusted to limit the travel of the armature so it does not strike
against the face of the core. The space between the armature and core is called the “air
gap”. The size of the air gap is critical to proper feeder operation. Instructions to adjust this
Air Gap are provided elsewhere in this publication.
Weigh Bucket
Product dispensed by the Product Feeders is deposited into the Weigh Bucket assembly for
weighing and final filling into the container. A strain gage loadcell mounted within the Weigh
Bucket determines weight and, when attained, the rotary actuator operates to open the
Bucket. Weigh Bucket components are shown in Figure 6.
Weigh Bucket volumes of 3l, 7l, and 12l are currently offered with the Model VF100e.
