1Safety instructions
1.1 Explanation of symbols and notes
Symbols: Assembly and commissioning must be carried out by qualified person-
nel 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 linear
feeder. This operating manual and, in particular, the included safety instructions have to
be observed by all individuals working with and on the linear feeder. In addition, all rules
and regulations regarding 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 linear feeder.
1.3 Intended use
The linear feeder is intended to convey component parts of different sizes, designs and
types of material.
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
1.4 Notes for Pacemakers and Defibrillators
Afag vibration conveyors are tested in accordance with regulation 15 of the German Statuto-
ry Accident Insurance Association [Deutsche Gesetzliche Unfallversicherung, DGUV] (previ-
ously BGV B11 of German Accident Prevention Regulations). The permissible values of ex-
posure 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 Im-
plants” remain unaffected by the above.
The alternating magnetic fields that occur in the immediate vicinity of certain vibration con-
veyors may affect the proper functions of active implants, i.e. pacemakers and defibrillators.
Anyone with active medical implants, for which no individual risk assessment has been pro-
vided, 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 LF linear feeder
2.1 General
The LF, together with a transport rail, is designed for feeding bulk materials.
The LF must only be used in combination with the corresponding Afag controller. This
combination guarantees optimum transport behaviour.
The LF must be fixed onto a sufficiently solid support, in order to avoid the conduction of
vibrations to other parts
2.2 Functional description
The LF is a unit which transforms electromagnetic oscillations in order to use them to
feed component.
The basic construction of the LF contains the following elements:
(see Figure 1)
1 Material to be conveyed
2 Feeder rail
3 Leaf springs
4 Jumping-off direction
αJumping-off angle
βInclination of leaf spring
Figure 1

R05.1 12/02/2020 Page 7
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 50Hz alternating current supply, the magnet achieves twice its maxi-
mum pulling force while this is independent of the direction of current flow. The magnet
thereby produces an oscillating frequency of 100 Hz. This 100 Hz oscillation is necessary
to achieve a smooth or gentle transport.
With heavy or large work pieces however, it is necessary to use an oscillating frequency
of 50 Hz. A half wave of the mains supply is thereby blocked.

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
When transporting the LF, it must be held and lifted at the support
only.
The transport rail is not to be held.
3.2 Installing the unit
The LF is firmly screwed to the foundation using the boreholes on the bottom. 2 screws
in case of the LF9 are affixed from below. The use of mounting plates allows the optional
mounting from above. (See Chapter 6.1 Mounting parts).
