3 Description of the device

The BF bowl feeder is used in conjunction with a bowl for storing, transporting, separat-

ing and sorting bulk goods. The transport motion is generated by vibration. The parts are

moved in the transport direction by micro-jumps.

The mass and the moment of inertia of the bowl used should not exceed the values and

tolerances specified in section 3.4 Technical data as otherwise the goods will not be

transported as well as possible.

The BF is designed in such a way that if the tolerance ranges for the mass moment of

inertia and mass specified in section 3.4 Technical data are observed, no mechanical

tuning is required.

If these tolerances are exceeded, mechanical tuning by fitting or removing leaf springs

will be necessary. Please note, however, that in this case perfect transport will no longer

be guaranteed. In addition the vibration force compensation system will be adversely af-

fected in this case, which means that more vibrations will be guided into the sub-

structure and this may affect the area around the machine.

BF feeders are to be operated in conjunction with an Afag control

unit. This is the only combination that will guarantee perfect

transport characteristics.

Afag BF bowl feeders use a vibration force compensation system based on the counter-

vibration principle. In this case a utility weight (1) vibrates exactly opposite to a counter-

weight (2). The utility weight is essentially formed by the mounting plate, the bowl and

the magnetic anchor, the counterweight is formed by the counter ring and the vibration

magnet. The utility and counter weights are secured to a base ring (4) by leaf spring as-

semblies (3). If the mass moments of inertia and mass specified in section 3.3 are not

exceeded when the utility and counterweights vibrate, exactly equal reaction forces are

generated, which are then transferred to the base ring (4) through the of leaf spring as-

semblies (3). As a result of this opposite vibration of the utility weight and counter weight,

these reaction forces almost totally cancel each other on the base ring (4).
