1Safety instructions
1.1 Notes on symbols and instructions
Symbols: Assembly and commissioning must be carried out by qualified personnel
only and according to these operating instructions.
Please observe the meaning of the following symbols and notes. They are grouped into
risk levels and classified according to ISO 3864-2.
DANGER
Indicates an immediate threatening danger.
Non-compliance with this information can result in death or seri-
ous personal injuries (invalidity).
WARNING
Indicates a possible dangerous situation.
Non-compliance with this information can result in death or seri-
ous personal injuries (invalidity).
CAUTION
Indicates a possibly dangerous situation.
Non-compliance with this information can result in damage to
property or light to medium personal injuries.
NOTE
Indicates general notes, useful operator tips and operating rec-
ommendations which don’t affect safety and health of the person-
nel.

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
c) in areas where readily flammable media are present
d) in areas where readily explosive media are present
e) in heavy polluted or dust- laden area
f) in aggressive area (e.g. saliferous atmosphere)

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)

3 Leaf spring
4 Projectile direction
αProjectile angle
βAngle of leaf spring inclination
γPitch angle of the spiral

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.
