1.2 Basic safety information
This operating manual provides the basis for the safe use and operation of the bowl feeder.
This operating manual and, in particular, the included safety instructions have to be ob-
served by all individuals working with and on the bowl feeder. In addition, all rules and
regulations concerning the accident prevention applicable for the site of operation are to
be complied with.
The operating manual must always be kept at the site of operation of the bowl feeder.
1.3 Appropriate use
The bowl feeders are intended for storing, transporting, separating and arranging compo-
nent parts of different sizes, forms and materials.
The workpieces must meet the following requirements in order to ensure a problem-free
operation:
-they must be free of oil, grease and burrs
-they must not be sticky
-they must not be statically charged
-they must not be magnetic (no self-magnetism)
-they must be free of dirt and not be mixed with foreign parts
-rubber parts can be powdered with talcum
WARNING
The KLF may not be used:
a) in damply and wet area
b) in temperature lower than 10°C or higher than 45°C

1.4 Notes for Pacemakers and Defibrillators
Afag vibration conveyors are tested in accordance with regulation 15 of the German Statutory
Accident Insurance Association [DeutscheGesetzliche Unfallversicherung, DGUV] (previously
BGV B11 of German Accident Prevention Regulations). The permissible values of exposure
area 2 are not exceeded, therefore no measures are required pursuant to Section 4 (2) of the
DGUV regulation 15. The definitions of Section 12 “Indirect Effects, Medical Implants” remain
unaffected by the above.
The alternating magnetic fields that occur in the immediate vicinity of certain vibration convey-
ors may affect the proper functions of active implants, i.e. pacemakers and defibrillators. Any-
one with active medical implants, for which no individual risk assessment has been provided,
must observe the specified safety distances to the vibration conveyors. The distances each
relate to the position of the upper body and the active medical implant relative to the field
source.

2Description of the device
2.1 General
In combination with a conveyor bowl, the bowl feeder is used for storing, transporting,
separating and arranging bulk material. The material is moved by vibrations. Parts are
moved by micro throws in the feeding direction.
The mass of the bowl should not exceed the value specified in chapter 2.4 as this cannot
ensure optimum transport behaviour.
2.2 Functional description
A Bowl Feeder is a unit which transforms magnetic oscillations in order to use the feeding
of work pieces.
The basic construction of a bowl feeder comprises the following elements.
(see Figure 1)
1 Material to be conveyed
2 Conveyor line
3 Leaf spring
4 Projectile direction
αProjectile angle
βAngle of leaf spring inclination
γPitch angle of the spiral
Figure 1

Page 8 16/05/2019 R01.0
The magnet, connected to the support, creates a force which attracts reps. releases the
oscillating plate dependent on the oscillation frequency of the power supply.
The pulsating movement of the oscillation plate causes the material to jump from the rail
at each oscillation and is conveyed as a result of the angle of inclination of the leaf springs.
On a cycle of the 50 Hz alternating current supply, the magnet achieves twice its maximum
pulling force while this is independent of the direction of the current flow. The magnet
thereby produces an oscillating frequency of 100Hz. This 100Hz oscillation is necessary
to achieve a smooth and gentle transport for small or light work pieces.
With heavy or large work pieces however, it is necessary to use an oscillating frequency
of 50Hz. A half-wave of the mains supply is thereby blocked.
2.3 Definition of the feed direction
The feed directions for the WV are defined as follows:
Left-hand (L), in anti-clockwise direction
Right-hand (R), in clockwise direction

3Assembly instructions
3.1 Transport
WARNING
Improper use of transport means (industrial trucks, cranes, tech-
nical aids, sling gear etc.) may lead to bruises and other injuries.
Required behaviour:
▪Observe and follow the transport and maintenance instruc-
tions
▪Proper use of transport means
CAUTION
During transport, the bowl feeder must only be held by the base.
Neither the bowl nor the selection elements are lifting points.
3.2 Installing the unit
For operation, theWV must always be mounted on a sufficiently pro-portioned foundation.
The type of fixing can be seen in the following drawings:
-WV with base plate (see Figure 3)
-WV with base plate and mounting foot (see Figure 4)
-WV with base plate and adjustment foot (see Figure 5)
When assembling the WV, it must be ensured that the base is horizontal.

3.3 Requirements for the bowl
In order to achieve optimum transport behaviour, the following basic requirements must
be fulfilled:
1. Combination bowl and WV must match each other
2. Selection resistant construction of the bowl
3. Control elements in the bowl must be oscillation resistant
3.4 Information for the construction of selection elements
Selection elements, which serve the sorting of the transported work pieces in the correct
orientation, must be of light but stable manufacture. The selection elements must be well
connected to the bowl so that no self-oscillations can occur which could cause possible
breakdowns.
The outlets must be as short as possible and must never run beyond the tangents of the
bowl. Constructional elements for outlet extensions must not be secured to the oscillating
system.
After the construction of selection elements, the oscillation system must always be re-
tuned to achieve an optimum conveying capacity.
Increasing of the conveying capacity by means of increasing the amplitude has an ex-
tremely negative effect on the system. Broken springs or inadmissible temperature in-
crease of the magnetic coil could be the result.
3.5 Power supply
WARNING
▪Any work performed on the electrical supply may only be
performed by trained, authorised, qualified personnel!
▪The power supply must be protected by an FI switch (pro-
vided by the customer).
▪The bowl feeder may only be operated with the power sup-
ply specified on the name plate.
The control device1 IRG1-S is used for the activation of the bowl feeder. The MSG801 or
MSG802 can also be used. Please note that an additional CEE connector plug is required
for the MSG controllers (Order number 11006982)
Installation of the plug is only to be carried out by technically qualified personnel.

4Operating instructions
4.1 Correlations between the transport speed and the WV spring packages
In principle, the WV and bowl are adjusted in the standard configuration. This means that
all oscillating elements of the system are optimally designed.
The following factors however influence the combination WV/bowl:
a) the parts to be conveyed (size, weight, shape, material and condition)
b) the conveying capacity
c) the quantity filled
d) the selection elements in the bowl (construction and arrangement). Selection ele-
ments always present additional weight
e) outlet in the bowl
f) support
g) environment (are there other oscillating components with a disturbing influence)
Procedure for adjustment of the oscillating system:
WARNING
Before removing the casing, unplug the mains cable!
1. check that the correct control unit is connected. Observe the Operating instructions
phase control unit
2. Remove the casing and check that all springs and fixing screws are tight.
3. check the magnet distance and set if necessary.
4. Switch on the bowl feeder and set the controller regulator to 90% (SE Position 8).
5. Slowly unscrew the lower fixing screw on a spring package.
Loosing this screw alters the transport speed of the parts in the bowl.

R01.0 16/05/2019 Page 13
The result:
Transport speed is reduced
a) insert additional springs
b) at first, one spring in one spring package
c) if this is insufficient, then one spring with spacer plate is to be inserted into the
individual spring packages one by one
Transport speed is increased
a) remove springs
b) the procedure and sequence are the same as for inserting springs
Irregular transport speed at bowl perimeter
a) a spring must be removed from the slower location
b) a spring must be inserted at the faster location
Erratic transport speed between two spring packages
a) seen, from the direction of transport, a spring must either be removed or inserted
behind the area of erratic transport speed.
CAUTION
The casing must be replaced after each procedure!

6.2 Control device
The WV is connected to the 230V/50Hz AC system via an IRG or MSG controller and can
be rated for other mains voltages and frequencies, e.g. 115V/60Hz. They operate in full-
wave mode at double mains frequency, i.e. at 50Hz AC, with a vibration frequency of
100Hz, in half-wave mode at single mains frequency with a vibration frequency of 50Hz.
Vibration displacement and thus the transport speeds are infinitely adjustable due to mag-
net current and thus magnetic force variability.
Soft-starting, all IRG and MSG types can be mounted in various different ways and offer
extra controls for photoelectric barriers, initiator elements, or extern 24VDC signal. For a
detailed description of the controllers refer full-range catalogue from AFAG GmbH.
Third-party controllers can also be used as long as they meet the technical requirements.
