Installation of the
Small Conveyor Drive
Chapter Outline
Unless the small conveyor unit was delivered with a working unit attached, the
channel, trough, or rail must first be bolted onto the small conveyor drive.
Afterwards, the entire small conveyor unit has to be positioned and bolted firmly
onto the base plate or the support.
3.1
Installation of the working unit
If the small conveyor unit was delivered by AViTEQ complete with the working unit
assembled, you may skip ahead to Chapter 3.2 „Mounting the small conveyor unit
on the base plate“ on page 7 now.
NOTE
3
3.1.1
Your own working unit
If you want to build your own working unit, please observe the following hints:
F The body of the channel has to be stiff to avoid bending. In the case of large
lengths/widths and low side walls, sideway folding of the edges or other stiffening measures may be required to achieve this. If required, ribs or rails have
to be attached. However, this must not interfere with the attachment of the
channel!
F Operating noise: the small conveyor drive generates a sound pressure level of
less than 70 dB(A) without considering the working unit or the transported
material.
NOTE
Depending on the construction of the working unit and the acoustic properties of
the material transported, the sound pressure level of the operational small conveyor unit may exceed 70 dB(A). It is the operator's responsibility to ensure adherence to the sound pressure level permitted by means of suitable noise protection
measures!
F The center of mass of the channel or rail should be within the front section
(outlet side) of the small conveyor drive.
F When placing the mounting holes, use the information in the AViTEQ leaflet
"small conveyor units“. Do not drill any additional holes into the small conveyor drive! Only use the threaded holes on the small conveyor drive!
©1999 AViTEQ Vibrationstechnik GmbH
Version 10/1999
3–1
Installation of the Small Conveyor Drive – Installation of the working unit
F For correct alignment of the vibration system, it is best to inform AViTEQ
Vibrationstechnik GmbH, Frankfurt, about the actual working weight (not
including transported goods) when ordering the small conveyor drive!
It is possible to run longer transport systems (channel or rail) with several successive small conveyor drives. Ask AViTEQ about it!
NOTE
3.1.2
Before installation
F Put the small conveyor drive onto a solid and flat surface!
F Have the mounting bolts for the working unit ready. Ensure that the bolts
have the correct length!
F The controller must be separated from the mains if it has already been connected to the small conveyor drive.
DANGER!
If there is insufficient support, the conveyor may fall off the assembly table and,
under the worst circumstances, may cause injuries. You should therefore ensure a
safe support!
F Follow the installation steps in the following diagram (see Figure 3.5 on page
5) and read the associated explanations. This procedure will simplify the
assembly for you!
3.1.3
Notes regarding the attachment with bolts
F Install the working unit by bolting it onto the small conveyor drive. Depending
on the version of the small conveyor drive, the bolts are inserted from above,
from the side, or from the face (positions no. 7, 8, and 9 in the installation diagram, Figure 3.5). The picture shows examples of KF drives for working unit
attachment from above and from the side:
F Only use the bolts specified for the individual small conveyor drives in
table 3.2!
F Please observe the tightening torques speficied in table 3.3!
F Ensure that the attachment bolts are not too long! If they are, the working unit
may not be able to be attached, or the bolts ends pointing to the inside
restrict the movement of the upper part of the small conveyor drive.
F Do not drill holes into the bottom of the channel! Protruding bolt heads
obstruct the product flow. Rather, you should use joints on the side or underside of the working unit for the attachment to the small conveyor drive.

If the weight of channel or rail is smaller, you will need to add additional
weight (e.g., spacer plates) to reach the specified working weight.
Low working weight results in low throughput! Do not commission the unit until
the working weight (without transported goods) corresponds to the specification
on the type label!
NOTE
4
If the weight of the channel or rail exceeds the working weight specified,
the small conveyor drive must be realigned at AViTEQ or on-site by AViTEQ
personnel (at customer’s expense).
Stopper-to-stopper operation due to excess working weight may mechanically
damage the drive! Never operate the unit with excess working weight! Send the
entire KF unit with the working unit to AViTEQ for alignment!

NOTE
Mounting the small conveyor unit on the
base plate
If the small conveyor unit with storage container (optional) was delivered by AViTEQ in a pre-assembled state, the following installation steps refer to the attachment of the structure comprising small conveyor unit, working unit, storage container and possibly a rattler, to the base plate. No additional rubber feet are required.
Only the complete small conveyor unit, i.e., the small conveyor drive and the working unit attached, is bolted onto the base plate or the support structure.
Base plate or support resonances may impair functionality and cause damage.
Ensure that the construction of the base plate or support structure is stiff enough to
resist oscillation!
ATTENTION!
3.2.1
Before installation
3
F Put the small conveyor drive onto a solid and flat base plate!
ATTENTION!
Damage to the small conveyor units or unsatisfactory throughput may result from
installation with an incorrect orientation! AViTEQ small conveyor units are suitable
for horizontal installation only. The deviation from horizontal position must not exceed 8°! The resting points of the feet must be on a plane, steps are not permitted.
AViTEQ offers a special version for suspended operation. Use this version only!
NOTE
F Have the mounting bolts for the small conveyor unit ready. Ensure that the
bolts have the correct length (cf. Table 3.9 on page 10)!
F The controller must be separated from the mains if it has already been connected to the small conveyor drive.
DANGER!
If there is insufficient support, the conveyor may fall off the assembly table and,
under the worst circumstances, cause injuries. You should therefore pay attention
to a safe support!
F Follow the installation steps shown in the diagram (cf. see Figure 3.7 on page
8) and read the explanations associated with each step. This procedure will
simplify the assembly for you!

Flow chart - explanations
Rubber feet are part of the shipment of AViTEQ small conveyor units. They
are already screwed to the underside of the small conveyor drive when the
unit is shipped. However, the rubber feet may become unusable following
plant modification or ageing due to environmental factors. They must be
exchanged if there is visible evidence of porosity, lack of elasticity, oily surface or other damage (cf. picture to the left).
Rubber feet destruction due to contact with oil! The rubber feet are not oil-resistant - avoid contamination with oil under any circumstances, ensure that the base
plate is clean, and that your hands are oil-free during installation. In oily environments, the rubber feet should be checked at half-yearly intervals.

Before you mark the drilling holes, you should take care when positioning
the small conveyor unit. Later, the working unit will have to vibrate freely
and should not strike against the neighbouring conveyor channels or rails.
The distance depends on the vibration width, which will be adjusted later!
In the case of working units with feeder or output funnels, the cuff used must not
impede free vibration of the unit. Observe appropriate cuff length and flexibility!

Sound pressure level
The small conveyor drive generates a sound pressure level of less than 70 dB(A)
without considering the working unit or the transported material. Depending on
the construction of the working unit and the acoustic properties of the material
transported, the sound pressure level of the operational small conveyor unit may
exceed 70 dB(A). It is the operator’s responsibility to ensure adherence to the
sound pressure level permitted by means of suitable noise protection measures!

Selection and Installation of
the Controller
Chapter outline
The drives of the small conveyor units must always be connected to the AC mains
using the appropriate controller. A suitable AViTEQ-VIBTRONIC controller is available for each version of the small conveyor units.
The chapter gives an overview over the possible combinations, the technical data,
and the terminology.
Individual information, connection options, and wiring diagrams may be found in a
separate, additional manual that is included with each controller.
4.1
Suitable controllers
The small conveyor units must be operated and connected via a special controller
to an AC mains with 50 or 60 Hz. The controllers are either included in the shipment from AViTEQ, or may be obtained from third party manufacturers under certain circumstances.
4.2
VIBTRONIC controllers
4
The VIBTRONIC controllers recommended by and available from AViTEQ permit an
adjustment of the vibration width and thus of the conveyance rate from almost
0 to 100 %. The controllers are available in several housing versions:
l
version in housing (IP 55): vibration width control and mains switch are
installed on the front side of the housing.
l
open version (IP 00 for SU... or IP 20 for SC...): vibration width control and
switch are included separately.
Operation without controller and connection to incorrect mains voltage/mains frequency damage the drive. Make sure that the connection values are correct and
compare them with the device’s type labels!
ATTENTION!

Controllers from third party manufacturers
Observe the following hints if you do not want to use an AViTEQ VIBTRONIC controller:
Amongst other information, you can find the following specifications on the type
label of an AViTEQ small conveyor unit:
l
Type
l
Vibration frequency in vibrations per minute
l
Drive voltage
l
Mains frequency
l
Drive current
When selecting a suitable controller, the drive voltage, mains frequency, drive current, and vibration frequency stated on the type label must be observed under any
circumstances!
F The specified values for current, voltage, and frequency must not be exceeded as the small conveyor unit may be destroyed by stopper-to-stopper operation.
F When checking the currents and voltages, use an RMS meter only. Do not
use an off-the-shelf multimeter as it cannot display non-sinusoidal values correctly.
F The third-party controller must generate a sinusoidal drive voltage. Operation
of the small conveyor drive with square wave voltages is not permissible and
may lead to the destruction of the drive!
4
Operation with an unsuitable controller or without controller, or connection to
incorrect mains voltage/frequency results in drive damage. Make sure that the
connection values are correct and compare them with the type labels! AViTEQ
does not accept responsibility if controllers of third-party manufacturers are used!

Selection and Installation of the Controller – Cabling
4.4
Cabling
When you install the cable between the small conveyor drive and the controller,
please observe the following:
F The cable length must not exceed 40 m.
F Only use cable whose insulation suits the special environmental conditions.
For pharmaceutical and food processing applications, you must choose sterilizable insulations.
F In the proximity of the small conveyor drive, run the cable in such a way that
contact with vibrating parts is impossible.
DANGER!
Short circuits and electric shock may result if insulation is damaged by rubbing!
Connecting cables must never come in contact with vibrating parts - otherwise,
the insulation may get damaged.
Run the cables in a way that excludes this danger!
F Avoid cable loops! Shorten cables if required.

Commissioning and
Operation
Chapter outline
After the installation of working unit, small conveyor unit, and controller you may
proceed to commissioning. Commissioning is carried out step by step, following a
flow chart.
Depending on the transported material’s properties, the working unit and the small
conveyor drive may be contaminated. Depending on the application, appropriate
cleaning agents will have to be used.
5.1
Commissioning
Commission the small conveyor unit by following the commissioning procedure
(Figure 5.1). Observe the explanations associated with each commissioning step:
1
Prerequisites: Have the following installation steps been carried out? Working unit (see Chapter 3.1), small conveyor unit (see Chapter 3.2), installation and wiring of the controller (see Chapter 4.2/4.3 and separate manual
for the associated controller)
It is impossibly to predict the behaviour of the small conveyor unit in this operating
manual if working units or controllers from third party manufacturers are used that
were not manufactured by AViTEQ. If necessary, contact the manufacturer!
5
NOTE

NOTE
©1999 AViTEQ Vibrationstechnik GmbH
The commissioning is carried out with the smallest possible vibration
width:
Before switching on the controller, turn the vibration width control (potentiometer at the controller) fully anticlockwise („0“ on the scale). This corresponds to the smallest vibration width.
The commissioning starts at the smallest vibration width, such that it is possible to
recognize problems due to installation errors in time. This is necessary as the
vibration behavior of the assembled small conveyor unit is still unkonwn. Example:
collision of the working unit with an adjacent conveyor component or stopper-tostopper operation.

24 hour test
Check after 24 hours of continuous operation and carry out remedial measures if
required:
ã Has the unit’s attachment come loose? Check the attachment of the rubber
feet! Are there cracks in the rubber feet?
ã Is the working unit still firmly attached to the support plate of the small conveyor drive? Check the bolts!
ã Turn the vibration width control (potentiometer) fully counterclockwise and
repeat all commissioning steps from step 2. The run-in of the small conveyor
unit may have resulted in the settling of parts and other mechanical changes.

Commissioning and Operation – Cleaning
5.3
Cleaning
Depending on the environmental condition and the properties of the material transported, the components of the small conveyor unit, in particular the working unit,
will be subject to varying degrees of contamination.
F Check the contamination level on a regular basis. Initially, check on a weekly
basis, thereafter check in intervals that you determine based on the requirements.
If the contamination is significant enough to impair the throughput, or there is a
layer of dirt on the small conveyor drive, it must be cleaned.
The cleaning may be carried out with pressurized air or steam, or with chemical
cleansing agents.
F Switch off the power to the drive before any cleaning operation!
F Select the appropriate method. If applicable, follow the guidelines for the use
of steam cleaners, water, or solvents that apply to the installation site!
F Only use cleaning solvents with a pH value of 7 or less!
F Do not use cleaning solvents containing chlorine!
F When cleaning with compressed air, observe any in-house regulations regarding dust!
F When cleaning with hot steam, there is a risk of damaging the paintwork.
Take care that the type label does not become detached!
DANGER!
Detachment of paintwork and contamination of the transported material! Do not
use agressive agents that could damage the paintwork! In the food processing
industry, only permitted cleaning agents and solvents may be used. Do not use cleaning agents that may attack the plastic insulation of cables!
F Remove all residues of transported material and cleaning agent after cleaning!
F Establish a sensible routine interval for contamination checks and cleaning!
Working units with conveying brushes or PU sheathing
F Remove loose dirt, chips, and dust with a vacuum cleaner; mop up oil,
grease, and emulsions with a cloth. Wash out any residue with soap water.

Maintenance and
Troubleshooting
Chapter outline
Even though the small conveyor units require little maintenance, it pays to check
the general state of the units in regular intervals in addition to the regular cleaning
of the exterior (see Chapter 5), and carry out maintenance if required.
Problems usually crop up during the installation and commissioning procedures.
This chapter helps you during troubleshooting and helps you avoid problems by
giving preventative advice.
6.1
Preventative maintenance
As a matter of principle, the AViTEQ small conveyor drives and associated equipment are maintenance-free. The units are designed to ensure that the properties of
the materials are retained even under the high vibrational stress during long-time
continuous operation.
Check on a weekly basis:
ã Does the small conveyor drive cause excessive noise? Establish the cause to
prevent damage to the equipment (see below)!
ã Are there any deposits of the material transported? Establish why - otherwise
the throughput will be affected! Deposits are caused by condensation processes or by problems with the material’s recipe.
Check after six months of operation:
ã Are the spring mounting bolts on the narrow side of the small conveyor drive
tight? They could have loosened due to the vibrations. In this case, thighten
the bolts with the specified torque (see Table 7.3). If this affects the adjustment of the eigenfrequency or the air gap, the small conveyor unit must be
realigned by AViTEQ.
6
ã What is the state of the rubber feet underneath the small conveyor drive? Is
the rubber porous or cracked? If so, all rubber feet of the small conveyor drive
must be exchanged.
ã What is the state of the working unit? Is the surface already significantly eroded? If required, the working unit must be replaced. Ensure correct weight of
the working unit, so that the vibration adjustment is not affected!

Maintenance and Troubleshooting – Troubleshooting
6.2
Troubleshooting
Two types of problems may occur:
DANGER!
l
Faults during installation and commissioning
l
Faults during operation
Disassembling the small conveyor unit and the controller carries the risk of
damage and lethal injury! There are no components inside of the units which could
be repaired or serviced by the user.Do not attempt any repairs! Never disassemble the small conveyor unit or the controller for repair purposes, not even if the
power is disconnected! In the event of device malfunction, ship the entire unit to
AEG Vibrationstechnik, Frankfurt, Germany! AViTEQ will ensure the fastest repair
possible!
Faults during installation and commissioning
l
Excessive heat-up to operating temperatures above 75°C on the magnetic
system and short circuits between windings
ã Check if the air gap is set too wide! An air gap that is too wide results
in an increased current consumption.
ã Check the working weight! Is it too large? The drive may be operating
in a critical range with power loss and increased current consumption.
ã Does the controller match the small conveyor unit? The small conveyor
unit isn't connected directly to mains by any chance, is it?
l
Knocking sounds and destruction of the small conveyor unit
ã Check if the air gap is set too narrow!
ã Check whether the working weight is too low!
ã Does the controller match the small conveyor unit? The small conveyor
unit isn't connected directly to mains by any chance, is it?
ã Have the spring mounting bolts been loosened? They must be tightened with a specified torque - otherwise the eigenfrequency will shift.
In this case, you should send the small conveyor drive to AViTEQ for
realignment!
l
Rattling noises
ã Check whether the working unit is firmly attached to the small conveyor drive and cannot move! For example, the attachment bolts of
the working unit may be too long and may hit the bottom of the
threaded holes.
6–2
Operating Manual for AViTEQ Small Conveyor Units KF and KR
l
Insufficient throughput and low vibration width
ã Check whether the working weight is too low!
ã Have the spring mounting bolts been loosened? They must be tightened with a specified torque - otherwise the eigenfrequency will shift.
ã Is the small conveyor unit able to vibrate freely? Does it rest on rubber
feet as required? If free vibration is impeded, throughput will be impaired!
ã Ensure that channel or rail are stiff against vibration and do not resonate within the small conveyor drive’s resonance band. In this case,
the drive power is absorbed by the channel/rail or the attachment
structure. In the worst case, something may break. Furthermore, other
conveyor units mounted on the same support may also be affected.
ã Check whether the attachment bolts for the working unit are too long!
If the bolts reach too far inside the small conveyor drive, they may
impede the free vibration of the upper part.
ã Ensure that the material transported does not form deposits due to its
consistency or particular environmental conditions leading to condensation! Deposits lead to decreased throughput and stopper-to-stopper
operation due to the increased working weight.
Faults during operation
l
Noise: do tone and volume change during operation? This points at unusual
wear, which may have its cause in, e.g., a change in the working weight or
the material transported.
ã Check whether the small conveyor drive is overloaded due to deposits,
a change in properties of the material transported, or due to other
changes to the process. Also check the state of the connector set.
ã Check whether the working weight could be increased by deposits on
the transport rail or the trough. This results in stopper-to-stopper operation and eventually in a rupture of the springs.
l
Broken springs or bolts on leaf springs. Have the springs replaced by the
manufacturer.
ã Check whether the unit has operated stopper-to-stopper (see above).
Are there deposits?
6
ã Has the vibration width increased? The maximum value must not be
exceeded (see Table 7.3 for values).
l
General failure of the small conveyor drive or the control unit
ã Check whether the environmental temperature at the time of failure
was between -25 °C and below +40 °C. The conveyor units only operate properly within that range.
l
Incorrect throughput
ã Check whether the height of the funnel outlet is correct and amend it if
required: If the height is lower, the throughput decreases, if the height
of the funnel outlet is larger, the channel may overflow.

Maintenance and Troubleshooting – Troubleshooting
Adjustment: the maximum height at the funnel outlet should be equal to the height
of the trough.
NOTE
l
Transported material freezes or sticks
ã Condensation may occur on metallic surfaces of working unit and
small conveyor unit following abrupt changes in temperature. Depending on the material transported, this may result in the formation of
lumps, material sticking to the surface, or even to material freezing to
the surface at low temperatures.
Remedy: Encapsulate the conveyor unit. If there is sufficient insulation, temperature changes are reduced and condensation is avoided.

Principles of Vibration
Conveyor Technology
Chapter outline
For the interested user, the following contains information about the principle of
functionality and the working of the small conveyor units. In this respect, the small
conveyor unit and its components are to be regarded as a resonant system that is
sensitive to alignment.
Design principles for the drive unit and the working unit are given, and framework
data is listed in a tabular form.
Detailed information may be found in the AViTEQ brochure „Equipment for transportation and measuring out of bulk materials (no. VIB 2.53)“.
7.1
Construction and principle of operation of
the small conveyor units
The AViTEQ small conveyor units are constructed in a modular fashion using the
following components
l
drive unit
l
connector set
l
working unit: channel, pipe, rail
l
storage container: funnel
Within a size category, it is possible to assemble a large number of combinations
from these components.
l
The construction principle of a small conveyor unit according to the figure
below shows the electromagnet (4) arranged in an angle a with respect to
the conveying surface.

Principles of Vibration Conveyor Technology – Alignment of the units
l
The support plate of the drive unit is firmly bolted to the working unit. Together they form a continuous mass unit within the resonance system (1).
l
The counterweight is the mass of the housing below. Both masses are connected by leaf springs (3).
l
Rubber feet (6) support the system with respect to its environment.
Smaller drives: each voltage cycle exerts a pulling force on the vibration system.
On a 50Hz supply, the unit will operate with 6,000 vibrations per minute.
Larger drives: For noise protection reasons, every second half cycle is suppressed
(3,000 vibrations per minute at 50 Hz).
By changing the voltage from the controller, the vibration width and hence the
throughput may be adjusted during operation from close to 0 to 100 %. The path
completed during a full vibration cycle, i.e., twice the amplitude, is called the working vibration width.
7.2
Alignment of the units
7.2.1
Two-body resonance system
Vibration drives are spring-mass resonance systems that exploit the resonance of
the vibration system. If the system is excited, it continues to oscillate with its
eigenfrequency, with a decaying amplitude depending on its attenuation properties.
If a sinusoidal force acts on this system with a frequency different from the eigenfrequency (frequency of oscillation or drive frequency), the entire system will no
longer oscillate at eigenfrequency (resonance frequency), but will follow the
rhythm of the force exerted on it (forced oscillation).
The closer eigenfrequency and vibration frequency (drive frequency) are, the larger the vibration width. However, for magnetic vibration drives, operation in the
immediate vicinity of the resonance frequency is not feasible:
l
Changes in the attenuation that are caused by different properties of the
transported material lead to significant variations in vibration width.
l
Exploiting large vibration widths close to resonance requires a wide air gap.
As the magnetic attraction is inversely proportional to the square of the width
of the air gap, the driving force does not remain constant.
Furthermore, for a stable operation of the resonant system, a well-defined
distance from the resonance frequency is required. In this case, the eigenfrequency may be lower or higher than the drive frequency.
7.2.2
Implementation in practice
In practice, the tuning may be accomplished by changing the working weight
(adding plates for additional weight):
7–2
Operating Manual for AViTEQ Small Conveyor Units KF and KR
l
Sub-critical operation by increasing the working weight: the vibration width
increases (eigenfrequency fe > drive frequency fa). AViTEQ small conveyor
units are tuned subcritically such that the vibration behaviour is very stable
and insensitive against attenuation. The eigenfrequency is at least 5 Hz above
the drive frequency.
l
Super-critical operation by increasing the working weight: the vibration width
decreases (eigenfrequency fe < drive frequency fa). The vibration width and
hence the throughput are subject to larger variations. The power consumption is higher.
7.3
Tuning data for the KF and KR series
Before delivery, small conveyor units without working units are factory-tuned for a
specified weight that is printed as „Nutzg.“ on the type label.
ã If the user installs a lower working weight, additional weights must be attached to the drive's support plate until the combined mass reaches the given
tuning weight.
ã If a heavier working weight is used, the original distance from the resonance
frequency must be restored by changing the leaf spring arrangement. For this
purpose, measurements of eigenfrequency, current consumption, vibration
width, and stopper voltage are required:
You change this...
...and get the following result:
increase the working weight
eigenfrequency decreases
decrease the working weight
eigenfrequency increases
increase the distance from the
resonance frequency
vibration width decreases
decrease the distance from the
resonance frequency
vibration width increases (stopper!)
increase air gap width
current consumption increases (see type label for maximum value), vibration width decreases, stopper voltage
increases
decrease air gap width
current consumption decreases, pulling force and vibration width increase, stopper voltage decreases (stopperto-stopper operation!)
more or thicker leaf springs
eigenfrequency increases, see distance from resonance
frequency
fewer or thinner leaf springs
eigenfrequency decreases

Principles of Vibration Conveyor Technology – Tuning data for the KF and KR series
Due to the complex tuning process, this work should be undertaken at AViTEQ
Vibrationstechnik’s laboratory. If the intended working weight is specified in
advance, AViTEQ will be able to tune the drive unit to suit. In an ideal situation, the
working unit constructed by the user should accompany the unit for the factory
tuning.
NOTE
When constructing your own working units, you should ensure that sideway folding of the (trough) edges or other stiffening measures are used to achieve sufficient stiffness of the working unit if larger dimensions, thin metal sheets, or low
side walls are used.
Note the following facts when making changes to drive and working unit! Additional technical data may be found in the AViTEQ brochure „Small Conveyor Units“.
