1.2 Basic safety information
Familiarity with these basic safety rules and regulations constitutes the fundamental pre-
requisite for safe handling and trouble-free operation of afag HLF linear feeders.
These operating instructions contain the most significant regulations for safe HLF opera-
tion. These operating instructions - and in particular the safety regulations - must be ob-
served by anyone working on and with the HLF. The applicable on-site accident preven-
tion rules and regulations must also be observed. These operating instructions must al-
ways be kept handy where the HLF is operated.
Operation of the hopper is only to be carried out by technically qualified personnel.
Qualified personnel are deemed to be persons who, by reason of their training, experi-
ence and instructions as well as their knowledge of the prevailing standards, regulations,
accident prevention regulations and operational conditions, have been authorized by the
people responsible for the safety of the system to perform the required activities, and
who are capable of recognizing possible hazards and avoiding them (definition of quali-
fied personnel as per IEC 364).
Any malfunctions that may have an adverse effect on the safety of any persons, the HLF
or other material assets must be eliminated without delay.
The following instructions are not only intended to ensure the personal safety of the op-
erators but also the operation of the products described and the devices connected to
them:
1.2.1 Electrical hook up
NOTE
▪Disconnect the power supply prior to assembling or dis-
mantling as well as when changing fuses or carrying out
installation modifications.
▪Observe all current accident prevention and safety regula-
tions applicable to particular cases of operation.
▪Check whether the rated voltage of the hopper coincides
with the local power supply prior to putting into operation.
▪All E-Stops must remain effective for all modes of opera-
tion. Unlocking the E-Stops must not, under any circum-
stances, cause uncontrolled restarting of the hopper.
▪The electrical connections must be safeguarded!
▪Ground wires must be checked for proper function subse-
quent to assembly!
▪Hook-up is only to be carried out by authorized personnel.

1.2.2 Specific danger points
NOTE
Afag HLF linear feeders are state-of-the-art equipment designed in
compliance with the EU Machinery Directive and accepted safety
regulations. Nevertheless, however, risks may arise from using
this equipment that may endanger life and limb of user or third
parties and cause interference with the HLF or other material as-
sets.
1.3 Intended use
The HLF is intended exclusively for the transporting and buffering of components and
can also be used for component sorting. For maximum permissible dimensions and
weights of add-on components, observe details in chapter 2.3 Table 1: Technical data,
chapter 3 Assembly instructions and chapter 4 Operating instructions. Appropriate use
also includes observation of all Notes in these operating instructions.
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)
None modification or reconstruction are allowed. The Tracks (in the chapter 4.1 Feeder
track design and in the chapter 3.3 Mounting of the useful mass) as well as the accesso-
ries (chapter 6) are excluded from this arrangement.
NOTE
Any use other than that described above is deemed to be improp-
er and will cause the warranty to terminate.
Also refer here to our general terms and conditions of sale.

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 device
2.1 General
Afag Type HLF-M Linear Feeders are used to remove parts from upstream machines
and/or feed parts to downstream machines. Afag Linear Feeders are also used for sort-
ing parts, with due consideration of various criteria. Linear feeders are fitted in individual
feeding units as well as in complex assembly systems.
The different types of Linear Feeders vary in size and application (see Table 1: Technical
data)
NOTE
HLF feeders are to be operated in conjunction with an Afag con-
trol unit. This is the only combination that will guarantee perfect
transport characteristics.
2.2 Functional description
HLF-M devices consist of two oscillating parts arranged on top of each other which oscil-
late asynchronously. Slotted leaf springs connect these to a common base plate at which
the opposing oscillating forces virtually cancel each other out. The oscillating part on top
is used as a structure (working weight) for attaching the feeder track. The lower oscillat-
ing part is the counterweight. A magnetic system (magnet armature –magnet core) is fit-
ted horizontally between the two oscillating parts. The positive features of the HLF-M
Linear Feeder are based on the balance of the working weight and the counterweight,
eliminating the majority of free oscillating forces directly in the machine.

A-evaluation
Various sizes are available (see Table 1: Technical data) depending on the area of appli-
cation and available space. The main criterion is the working weight (track length) and
the space available for installation.
Two Afag Linear Feeder versions are available: 230V/50Hz and 115V/60Hz.
Various Afag control devices (see chapter 6.3 Control device) are available for controlling
the Linear Feeder.

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 linear feeder must only be held by the base.
The linear track is no lifting point.
3.2 Installing the unit
The HLF-M is firmly screwed to the foundation structure by means of slots provided in
the base plate (see Figure 2). This precisely defines the interfaces where the feeder
track enters and exits as well as allowing adjustment. The substructure should be non-
oscillating in a horizontal plane in order to be able to take up any residual forces. Self-
supporting profile constructions have to be reinforced with a base plate to which the Lin-
ear Feeder is attached. A steel plate of at least 20mm thickness and a width of over
120mm should be used for this purpose. The vertical oscillating forces responsible for
energy induction in the foundation structure should be virtually completely eliminated by
a careful balance of weights (see chapter 4.2 Balance of weights). Height adjustments
can be achieved by means of appropriate substructures. Standard Afag components are
available for setting up complete units.

3.3 Mounting of the useful mass
3.3.1 General
The HLF-M Linear Feeder is based on a balance of the oscillating forces by the principle
of opposing oscillation (push-pull). In order to ensure an effective balance of oscillating
forces, it is necessary to keep the lines of action of the centres of gravity of the working
weight and counterweight as close together as possible. The position of the centre of
gravity of the counterweight is determined by the Linear Feeder design. The centre of
gravity of the working weight is determined by the construction design specified for the
working weight (e.g. feeder track). In order to ensure a good balance of oscillating forces
with minimum residual oscillation, the overall centre of gravity of the working weight has
to be located within the area specified in Table 2: Limiting coordinates for the position of
the centre of gravity of the working weight.

3.3.2 Mounting a linear track
The feeder track is attached by means of a side plate (see Figure 4). The side plate is
fixed precisely and reproducibly using fitting pins. Vertical slits in the side plate are pro-
vided for feeder track attachment, allowing fine adjustment of the track entry and exit in-
terfaces in a vertical direction.

HINWEIS
The useful mass has to correspond to the values specified in chapter
4.2 Balance of weights.

3.4 Power supply
WARNUNG
▪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 linear feeder may only be operated with the power sup-
ply specified on the name plate.
The control device IRG1-S is used for the activation of the linear feeder. The MSG801 or
MSG802 can also be used. Please note that an additional CEE connector plug is re-
quired for the MSG controllers (Order number: 11006982)
Installation of the plug is only to be carried out by technically qualified personnel accord-
ing Figure 6: End of the wire for additional plug.

4Operating instructions
The first step in adjusting the linear feeders is always to balance the masses and then to
adjust the natural frequency.
4.1 Feeder track design
The linear tracks must be unyielding so that the transport pulses generated by the unit
are fully transferred to the work pieces and no superimposed natural vibration can ad-
versely affect the transport process. This requirement has priority over mass reduction
measures. The preferred material for linear tracks is tool steel (e.g. 1.2842, 90MnCrV8).
Linear track design should adhere to the useful masses specified in chapter 2 Table 1:
Technical data and Table 4: Obligatory values for the working weight
The following size ratio should be aimed for with regard to the feeder track cross-section:
𝐻𝑒𝑖𝑔ℎ𝑡
𝐵𝑟𝑒𝑎𝑑𝑡ℎ =2 1
The recommended dimensions are listed in Table 3: Linear track dimensions. The di-
mensions are for one vibrating section and can be applied to each of the two vibrating
sections.

4.2 Balance of weights
The oscillating forces in the base plate of the Afag Linear Feeder are compensated al-
most completely due to the principle of opposing oscillations (push-pull). This balance of
oscillating forces is however only achieved if:
1. The working weight and the counterweight are balanced as closely as possible.This
means that the working weight and the counterweight are equal. The working weights
specified for respective sizes are listed in Table 4 below. The working weight is the total
weight of all components attached to the mounting plate including the side plate. The
balance of weight is verified by simply weighing the working weight.
2. The centre of gravity of the working weight is located in the range represented in Fig-
ure 3.
Both conditions have to be taken into consideration at the construction stage of the feed-
er track. An optimal balance of weight is achieved when almost no residual vibrations
can be detected in the substructure.

NOTE
Useful and counter masses should correspond to the values
specified in Table 4.
NOTE
1. Masses are fully balanced if hardly any vibrations are no-
ticeable in the floor.
2. When masses are fully balanced, the transport speeds at
useful and counter sides are identical.
4.3 Fine adjustment of natural frequency
The Afag Linear Feeder is a spring/weight based vibrating system that operates by mak-
ing use of resonance. Weights that are not exactly balanced require a spring stiffness
modification. Movable adjustment plates are provided at the base plate attachment of the
spring assemblies (see Figure 7). The natural frequency can be adjusted by moving
these adjustment plates.
Figure 7: Spring assembly with adjustment plates
The Linear Feeder always has to be adjusted ‘subcritically’, i.e. the inducing frequency
has to be about 5% less than the natural frequency. This means that a natural frequency
of about 97Hz is required for a 100Hz feeder, and a natural frequency of about 117Hz is
required for a 120Hz feeder.
Adjustment plates
Adjustment plates

R05.0 16/05/2019 Page 17
Adjustment should be carried out as follows:
Put a test part on the feeding track and switch on the control device. Use the turning
knob to reduce the feed rate of the Linear Feeder until the part on the feeder track is only
moving slowly. Maintain the control device setting and slowly unscrew the adjustment
plate screws of a spring assembly of the Linear Feeder (see Fig 5). Check the feed rate
of the test part while loosening the screws. If the feed rate first increases briefly and then
starts to decrease on further loosening the screw, the Linear Feeder is not adjusted
properly, with the natural frequency slightly above the inducing frequency. The adjusting
plates have to be reset to the position they were in before loosening the screws.
If the feed rate increases when the screws are loosened and does not or only minimally
decrease when fully unscrewed, the Linear Feeder adjustment is too stiff, i.e. the natural
frequency is still too high. The adjustment plates have to be pushed downwards or, if the
weight difference is significant, a leaf spring may have to be removed. The test has to be
repeated afterwards.
If the feed rate decreases immediately on loosening the screws, the Linear Feeder ad-
justment is too soft. The adjustment plates then have to be pushed upwards or if neces-
sary, an additional leaf spring has to be fitted. The test has to be repeated afterwards.
When moving the adjustment plates, it should be kept in mind that the adjustment plates
always have to be horizontal and exactly opposite to each other.
Adjustment plates up Natural frequency increases
Adjustment plates down Natural frequency decreases
CAUTION
It is vital that the linear feeders be 'subcritically' adjusted (i.e. the
natural frequency must be about 5% above the exciter frequency)
as otherwise the magnet may overheat and burn out, and the
transport speed may decrease as soon as components are placed
upon the linear track.
To avoid the vibrating sections from subsiding, make sure to loosen the adjustment
plates of one spring assembly only at a time during frequency setting.
NOTE
The adjustment plates must be aligned horizontally. The top edg-
es must always be arranged opposite each other.

Page 18 16/05/2019 R05.0
4.4 Setting the air gap
During series assembly, the air gap of the magnet system is set to the values specified in
Table 5. If this air gap deviates from the values specified in Table 5, e.g. after a natural
frequency adjustment, then this has to be reset. The cover is removed for this purpose,
and the side attachment screws of the armature are unscrewed and the air gap is read-
justed using a distance gauge (Table 9).
Figure 8: Armature attachment
The values specified in Table 5 are only applicable for the respective power supply.
When making adjustments, it is imperative that the surfaces of the magnet core and ar-
mature are exactly parallel to each other. To achieve the required precision, it is neces-
sary to tighten the screws alternately and in stages.

5Maintenance Instructions
An HLF-M type linear conveyor requires minimal maintenance. Depending on the man-
ner in which it is used, signs of wear may occur, which can be compensated for by reset-
ting the adjustment plates.
Spring wear/ oxidation (increased resonance frequency)
Depending on the operating mode and environment, a layer of oxidation may develop on
the springs at the contact surfaces which over time may adversely affect the vibration
behavior. In cases such as these, the resonance frequency will increase and it may be
necessary to compensate for the increase by lowering the adjustment plates.
Spring setting behavior (reduced resonance frequency)
The result of longer storage periods may be that installed springs can show a setting be-
havior, and in consequence a reduction in the spring stiffness and reduced resonance
frequency. In this case, the resonancy frequency can be re-calibrated, which may cause
the spring stiffness to be reduced as well as a drop in the resonance frequency.
In some cases, it may be necessary to remove the leaf springs to clean them or, if they
are heavily worn, to replace them entirely. Here, the vibration parts must be supported in
vertical direction. Then, only one spring package at a time may be removed, because
otherwise the vibration parts would move, making it impossible to guarantee that they
function properly.
CAUTION
The leaf springs must not be oiled or greased as this would make
the springs sticky and in turn adversely affect the vibration re-
sponse.
