3. Construction and function of the linear feeder
8 Part Feeding 7.0 Hopper & Hopper Controller Rev.5
3. Construction and function of the linear feeder
Linear feeders are used for the actuation of conveying equipment. The actuation takes place
by an electromagnet. The following schematic diagram shows the function of a linear
feeder:
The linear feeder is a device of the family of vibratory bowl feeders. It is, however, equipped
with a linear conveyor. Electromagnetic vibrations are converted into mechanical vibrations
and are used for conveying material B. If magnet D, which is securely connected with the
counter mass F, is supplied with current, it generates a power that, dependent on the
vibration frequency of the mains supply, attracts and releases armature E. Within a period
of the 50 Hz of the A.C. network the magnet achieves its maximum power of attraction
twice, as this is independent of the direction of the current conduction. The vibration
frequency therefore is 100 Hz. In case a half-wave is locked, it is 50 Hz. Please take the
vibration frequency of your linear feeder of the table described in 1. Technical data.
A linear feeder is a resonant system (spring-mass-system). The result is that the adjustment
made at the factory will rarely meet your requirements. Chapter 5 describes in detail how
your linear feeder is adapted to your requirements.
Controlling of the linear feeder takes place by a low loss electronic control unit type ESG
1000. At its front panel it is provided with a 7-pole plug-in connection, by which it is
connected to the linear feeder.
The pin assignment of the socket is shown in the table described in 1. Technical data.
For more information on the complete range of control units,
please refer to Hardware (Hopper Controller).
All control units have got two main operating elements:
-By the mains switch the linear feeder is switched on or off.
-By the turning knob the conveying capacity of the transport unit is set.

Part Feeding 7.0 Hopper & Hopper Controller Rev.5 9
4. Transport and mounting
Transport
Take care that the linear feeder cannot dash against other things
during transport.
The weight of the linear feeder is taken from the table described in 1. Technical data.
Mounting
The linear feeder should be mounted on a stable substructure (available as an accessory part)
at the place where it is used. The substructure must be dimensioned in a way that no
vibrations of the linear feeder can be carried away.
The following table will give you a summary of the bore data of the various types:

5. Starting
Ensure that the frame (stand, base, frame etc.) is connected
with the ground wire (PE). If necessary, prediction earthing
on spot should be provided.
Check, whether
-the linear feeder stands in an isolated position and does not come in securely with a
solid body
-the linear track is screwed down and adjusted
-the connecting cable of the linear feeder is plugged in at the control unit.
WARNING
The electric connection of the linear feeder may only be made
by trained personnel (electricians). In case modifications are
made at the electric connection, it is necessary to observe the
operating “Hardware (Hopper Controller)”.
-The available supply voltage (frequency, voltage, output) is in accordance with the
connection data of the control unit (see type plate at the control unit).redf
Plug in the mains cable of the control unit and switch on the control unit by the mains switch.
The optimal operative range of the linear feeder is at a controller position of 80% at the
control unit. In case of higher deviations (>=±15%) a readjustment should be carried out.
5.1 Adjustment
With spring assemblies for a conveying track weight, which is approx. 25 % lower than the
maximum track weight described in 1. Technical data, and a running speed of 4 - 6 m/min.
In case heavier or lighter conveying tracks are installed or considerably faster or slower
conveying speeds are required, the spring assemblies must be modified. For that the
following basic rules must be observed:
At first a rough adjustment of the conveying speed
(adjustment of the natural frequency) must be made, which is
followed by the adjustment of the running behavior. Finally
you adjust the conveying speed (natural frequency).

5.1.1 Adjusting the required running speed
In case the required running speed is not achieved with the standard spring assembly, the
current adjustment range of the oscillating system must at first be found out, either natural
frequency below 50 or 100 Hz or natural frequency above 50 or 100 Hz.
For that one or two plates are dismounted from the movable counterweight for a trial. If a
change in the running speed on the conveying track is recognized, it can be taken from the
table below, whether springs must be installed or removed. The controller position at the
control unit may not be changed during this trial. In the factory the different sizes are
equipped.

The following graphic chart shows the resonance curve of a linear feeder:
The resonance curve of the linear feeder may not correspond
to the mains frequency.
When exchanging the springs the valency of the various leaf spring sizes must be considered.
As the spring size enters into the spring power in square, the following examples must be
observed:
-2.5 mm spring size = 6.25 spring power
-3.0 mm spring size = 9.0 spring power
-3.5 mm spring size = 12.25 spring power
A 3.5 mm leaf spring has about the same valency as two 2.5 mm leaf springs. For that
reason, it is recommendable to carry out the final or fine adjustment always with thin leaf
springs.

When changing the masses of counter and oscillating weights
(installation or dismounting of counter or additional weights)
the running speed or the natural frequency of the linear feeder
is changed. If necessary leaf springs must be added or
removed.
Changing the spring assembly for linear feeder’s type SLL 400
Unscrew the 4 or 6 upper lateral spring fastening screws (“C”) (M6 DIN 912). The complete
oscillator with mounted track can now be lifted upwards. Remove the desired spring pack
by releasing the lower lateral spring fastening screws (“D”) (M6 DIN 912).
Before removing the spring pack, the protective conductor on the feeding side must be taken
out from the lower spring fixture.
Screw the removed spring pack into the mounting device for fitting springs size 400 and
fasten it in a vise. When installing and removing the laminated springs, make sure there are
little distance plates between the springs.
If you do not have a mounting device for spring packs, proceed as follows:
Fix the dismounted spring pack horizontally in a parallel vise with smooth clamping jaws
and perform the desired adjustments. When tightening the spring packs, make sure they are
in parallel alignment.
The mounting device aligns the two spring fixtures to one another. The fastening screws of
the springs are to be tightened with a torque of 12.5 Nm.
Reinstall the complete spring pack
To restore the former alignment of the linear feeder, the adjusting bore on the upper counter
mass end (“E”) must be aligned to the oscillator with a pin (6 mm in diameter with a
minimum length of 70 mm).
On the feeding side, the oscillator is aligned near the counterweight by inserting another pin
(6 mm in diameter with a minimum length of 70 mm) into the adjusting bore (“I”).
After having adjusted the spring angle to the desired position, the lateral fixing screws are
tightened again with a torque of 12.5 Nm.
Before putting into operation again, please remember to remove the centering pins.

5.1.2 Adjusting the required running behavior or the synchronism of the
linear feeder track
In order to achieve synchronism of the linear feeder track, the spring angle must be adjusted
the same as the gravity center angle. The gravity center angle is determined by the position
of the two gravity centers of oscillating and counterweight.
Example with a gravity center angle of 12.5 °
Spring angle equals gravity center angle
The force direction of the springs is initiated exactly on the gravity center of the vibrator.
Consequence: The height amplitude is the same at the feeding and at the discharge side.
Spring angle larger than the gravity center angle
The force direction of the springs is initiated before the gravity center of the vibrator.
Consequence: The height amplitude is higher in the feeding area than in the discharge area.

5. Starting
14 Part Feeding 7.0 Hopper & Hopper Controller Rev.5
Spring angle is smaller than the gravity center angle
The force direction of the springs is initiated behind the gravity center of the vibrator.
Consequence: The height amplitude is smaller in the feeding area than in the discharge area.
In case the angles are not the same, the conveying tracks are running unsteadily. In case of
very high deviations of this angle the conveying track can even show lateral deflections
(oscillations).
The gravity centers or angles can be influenced by the following measures:
-Add or displace counterweight (“F”)
-Choose the track position and height in a way that a favorable gravity center is achieved
-Keep the track weight as low as possible, in order to keep the vibrator gravity center as
low as possible.
-Install an additional counterweight in the vibrator discharge area (“G”).
-Adjust the spring angle to the gravity center angle
The spring angle of the linear feeder’s type SLL 400 can be adjusted between 5° and 25°.
If the gravity center angle is outside this area, synchronism of this track is impossible. In
this case modifications must be made at the counter and oscillating weight gravity centers
according to the points listed above.
Spring angle adjustment
Fix the vibrator towards the counter mass (refer to 5.1 Adjustment). After that the four
lateral spring fastenings (“C” + “D”) can be loosened, in order to swing the spring assembly
into the desired spring angle. After that fasten the spring fastening screws with the
permissible tightening torque (refer to 1. Technical data) and remove the adjusting screws,
distance plates or bolts.
Adjustment of the magnet air gap
The air gap between armature and magnet adjusted in the factory can be taken from 1.
Technical data.
The adjustment of the air gap can be made from the outside without dismounting any
component parts. Slightly loosen both armatures fastening screws (“A” or “A” + “B”) (M5
DIN 912 at linear feeder type SLL 400:). In both bore holes in the oscillating profile (“H”)
a round pin (Φ1mm, 80 mm long at SLL400; ) must be stuck through. By pressing both
armature fastening screws against running direction and subsequent tightening the specified
magnetic gap is adjusted (refer to 1. Technical data). After that pull out the round pins. In
case there are no round pins, the magnetic gap can be adjusted from below (perhaps after
dismounting the complete linear feeder from the supporting structure or from the supporting
table) by means of a feeler gauge or distance pieces according to the prescribed magnetic
gap.
At a turning knob position of 100% at the control unit and a
correctly adjusted magnetic gap the magnet may not dash
against the armature. In case this happens, proceed
according to point 5.1 Adjustment (remove springs).
