PARU Mini is a standardized platform for presenting bulk parts in properly oriented and singulated manner in
automated production or assembly lines. For this purpose, PARU Mini is associated to product-specific
tooling (rail) and integrated - on its own or as part of a feeding system - into a production or assembly line at
the user’s. PARU Mini requires no manipulations. The complete tuning/ matching of the system is done in
RNA’s factory by means of simulation-based system engineering in accordance with user’s requirements.
PARU Mini is an incomplete machine as defined by the Machinery Directive 2006/42/EC.
PARU Mini can be retooled at any time in order to feed other parts. The tooling units adapted via simulation
tools offer a Plug&Feed capability, meaning that production can start right after mounting the adapted tooling
on the PARU Mini, without any adjustments to the drive. PARU Mini thus provides for flexible feeding of parts
at high rates and with short retooling times.
PARU Mini is a precisionmachine. To fully exploit its functionality it is imperative that you use this
product in conformity with this operating and installation instruction manual. Beside the
configuration of the tooling, the controller settings and the condition of the parts handled must
comply with the specification document and the parameters set up during the simulation-based
matching phase if the desired function is to be achieved.

Notice!
Noise emission: constant sound pressure level (without parts) < 70 dB (A)
Noise emission depends on the parts to be fed and can therefore be measured only at the site of
installation, under real-world conditions. If the sound pressure level exceeds the acceptable limit,
suitable noise reduction measures need to be taken.

To ensure constant feed rates even in production facilities with powerful consumers and fluctuating mains
voltages we recommend the use of optimized controllers supplied by Rhein-Nadel Automation GmbH. If you
wish to operate a PARU Mini with a third-party controller please contact Rhein-Nadel Automation.
Notice
For smooth operation some minimum requirements must be fulfilled at the site of installation. The
base must be as rigid and stable a structure as possible. We recommend a minimum mass of
20kg for PARU Mini XS and 30kg for PARU Mini S.

PARU Mini drives do not require the operator to take care of selecting the right operating mode. The operating
mode is determined by a code in the RNA vibrating drive connector. A wire jumper from pin 3 to 4 in the
connector switches the controller to mode 2: 100 or 120 Hz. In the absence of this wire jumper the controller
operates in mode 1: 50 or 60 Hz.
The RNA vibratory drive systems come with the right code in the connector.
Fig. 4: Pin assignment
Notice
Where frequency controllers with selectable output frequency are used, an EMC metal gland and
a shielded cable are provided.
The vibratory feeder is controlled by a low-loss electronic control unit. The choice of the control unit depends
on the power input of the feeder. The available choice of controllers is shown in the following table:

PARU Mini is a two-mass system. With PARU Mini, exciter mass and useful mass are connected to each
other by spring leaves inclined at a fixed angle. The usable mass also includes the tooling. The vibratory
system is excited by magnets. This results in an oscillating motion of the usable mass. This motion
accelerates the parts in horizontal and vertical direction, causing them to move along the tooling. PARU Mini
oscillates in the range of 100Hz (EU) resp. 120Hz (USA). The vertical amplitude is up to 30µm, the horizontal
amplitude is up to 150 µm.
Fig. 4 illustrates a PARU Mini XS unit with a typical tooling (4) shown green.
Fig. 4: PARU Mini XS with tooling (shown green)
The parts handled are finally oriented and buffered by means of the tooling (4) and the part-specific sorting
elements. Two M6 or M8 screws are used to fasten the PARU Mini to its mount via the stationary baseplate
(1). The exciter mass (2) and useful mass (3 and 4) are the vibrating components. The tooling is part of the
useful mass and is fastened to the useful mass plate (3) by means of clamps, for example. The connection
for user’s earth (5) is located on the baseplate.
We recommend you to observe following general conditions when designing tooling units for PARU Mini.
The tooling must be a rigid body in order to transmit the motion of the useful mass in the best possible way.
We recommend a feed rail height-to-width ratio of 2:1 or higher. We recommend the use of threaded
assemblies suitable for rigid bodies.
To ensure stability of the PARU Mini with minimum transmission of bearing forces to its mount, the rail should
not exceed the maximum weight stated in chapter 2.2.
The tooling centre of gravity should be located in the middle of the PARU Mini, and the centrifugal moment
about the feeding axis of PARU Mini should be close to 0.
For virtual validation of the feeding behaviour and system tuning/matching we recommend to design the
tooling using the CAD dummy for PARU Mini and the simulation tool of Rhein-Nadel Automation GmbH.

3. Installation Instructions
3.1. Shipping and handling
3.2. Installation

|12
Reception by user of the parts presented by a tooling of the PARU Mini must be ensured.
Check following items before starting the feeding system:
Danger! Attention!
•All shipping braces are removed and all screws and bolts tightened firmly.
•The drive is properly aligned and fastened in place without any strains or stresses exerted on
the base plateand/or substructure.After that check smooth carryover of theparts onthe feeder
transition points.
•The transitions to downstream equipment are perfectly aligned with no interferences.
•The vibrating motors are standing free without contact to any solid body.
•The compressed-air supply (if required) is available and stable. The required operating
pressure is shown in the table. The cross-sectional areas at the connections are to be adapted
to the connection union or coupling (if provided).
•All guards and safety devices are in perfect working condition.
•No objects and (bulk) parts are inside the machine.
•The motor connecting cables are plugged into the requisite control unit.
•The available electricity supply (frequency, voltage, power) correspondsto the connectiondata
of the control system.
•The control units have been set up as specified.
Make sure that the machine frame (rack, substructure, etc.) is connected to the protective earth
conductor (PE). Protective earthing has to be provided by user as necessary.
Electrical connection of the PARU Mini and its components as well as commissioning of the system must
only be carried out by professionals in accordance with the rules and regulations of the country where the
PARU Mini is operated! When making any change to the electrical connection be sure to observe the
operating instructions for the control unit used.
As PARU Mini is incomplete machinery, the interaction between PARU Mini and user's receiving station is to
undergo a risk analysis to be conducted by user. Should this risk analysis reveal that any measures are
required, thesemeasures are tobe implementedby user. EmergencyOff switches are not providedon PARU
Mini. This function has to be implemented by the manufacturer of the complete system/machine. Maintain
unobstructed access to Emergency Off switches at all times. Check proper operation of the Emergency Off
switches every day at the beginning of the machine operation.
Do not put the PARU Mini into operation until it has been incorporated into or assembled with the
entire system and the safety requirements of the EC Machinery Directive for the entire system
are met.
First power up:
Once the previous steps have been carried out switch the PARU Mini on without parts and at a low amplitude
(using a starting value of 10%, for example). Now increase the amplitude step by step until you reach the
target value defined for the tooling. Make sure that the useful mass and the exciter mass of the PARU Mini
do not knock into anything.
If the first start-up of the PARU Mini is accompanied by loud noises, please check that: All threaded fasteners
have been selected and tightened in accordance with the Technical Data.
•
•The air gap is correctly set in accordance with the table.
•The transitions from the upstream feeding system, to the escapement or into the tooling are correctly set
up.
Otherwise please contact Rhein-Nadel Automation GmbH.
The optimum feed rate of PARU Mini for one or several parts of Buyer has already been
determined in RNA Digital Solutions GmbH’s factory. We strongly recommend that you not
deviate from the amplitude and frequency defined for the respective tooling.
3.3. Commissioning

|13
If PARU Mini runs smoothly at the target frequency and amplitude associated to the tooling, the upstream
process (feeding system) can be started with parts for final adjustment of their transition to the PARU Mini.
For operation of the PARU Mini observe the following items:
In standard configuration the feeding system is switched on and off via the controller. Equipment users have
the possibility of interfacing this controller with their higher-level machine controllers.
Take great care to prevent parts from backing up into the tooling of the upstream feeding system, forexample
by stopping the feeding system via the controller.
If compressed air is used at the tooling be sure to keep a constant operating pressure and be advised that
the air supply must not be switched off during operation. On start-up or re-starting make sure that the
operating pressure is reliably available before the PARU Mini starts.
The set air and sorting nozzle positions must not be changed.
Operators must have free access to the PARU Mini at all times.
NEVER remove jammed parts from the PARU Mini unless it has been shut down completely. Proceedwithout
damaging the product or the tooling! Be advised that PARU Mini is a precision machine where tooling defects
as small as a tenth of a millimetre may already impair the function.
If you observe all operation and installation instructions in this manual the PARU Mini will require no
maintenance.
PARU Minimust be operated by trained professionals only. Observethe installation and operating
instructions at all times. Operation of PARU Mini is permitted only if the enclosure is installed and
user’s safety circuitry is functional. Operators assigned by the equipment user can be trained on
the PARU Mini by Rhein-Nadel Automation GmbH. Please ask for the terms and conditions of
such training if required.
Depending on the parts handled the PARU Mini may emit a high noise level. Therefore we
recommend that you wear ear protection for any working on and around the PARU Mini.
Even when stopped the PARU Mini should not be assumed to be in a safe state. Stored energy,
for example from the leaf springs, may be released unintentionally or through maintenance
procedures not in accordance with instructions. This applies in particular to procedures that may
be dangerous if carried out whilst the machine is in operation, e.g. the clearing of a jam, which is
against the recommendations of this instruction manual.
For tooling changes of the PARU Mini observe the following items:
1. Switch off PARU Mini,
2. Switch off the compressed air supply (if provided)
3. Unscrew the tooling segments.
4. Disconnect compressed air lines (if provided).
5. Store the dismounted tooling at an appropriate location that satisfies the requirements specified in
chapter 5 of this operating and installation instruction manual.
6. Perform the quick-emptying and changeover procedure for the upstream feeder system to
completely remove all previous parts.
7. Mount the new tooling on the PARU Mini. Take care that the transfers from / to the upstream /
downstream processes are adjusted with utmost precision.
8. Feed the parts to the upstream process. Operate the PARU Mini in accordance with chapter 4.1 of
this operating and installation instruction manual.

Strong temperature variations must be avoided. After prolonged storage the unit must be cleaned in
accordance with chapter 4.3 of this installation and operating instruction manual.
Disconnect power and compressed air before dismounting the PARU Mini from its target system. Remove all
parts from the system. Loosen the M8 fastening screws. For the rest observe the instructions in chapter 3.1
"Shipping and Handling". We recommend that you keep the cardboard box in which the PARU Mini unit was
delivered in case you should need to return the PARU Mini to Rhein-Nadel Automation GmbH.
The components of the PARU Mini unit are mainly steel and aluminium. Units which are no longer in use
should not be disposed of as complete units but dismantled and the component parts recycled according to
their materials. Please contact Rhein-Nadel Automation GmbH if you want to return the PARU Mini unit.
Spare parts must satisfy the technical requirements specified by us. This is always ensured if genuine spare
parts are used. We assume warranty only for the genuine spare parts supplied by us. The installation and/or
use of spare parts not supplied by us may have a negative effect on design characteristics and thus impair
active and/or passive safety. We do not assume any liability or warranty for damage due to the use of other
than genuine spare parts or accessories.
Please address your spare parts orders to our customer service department.
For a smooth and swift execution of your spare parts order we need following information:
1. Name of customer:
2. Machine identification
3. Designation of spare part required
4. Required quantity
5. Requested mode of shipment
Q
'I have installed the PARU Mini unit in accordance with these installation and operating instructions
but it won’t run.'
A
First, check that:
The controller settings are correct (frequency, amplitude).
The tooling is installed in its original condition and positioned correctly, i.e. no masses have been
removed or added by user.
All threaded fasteners have been selected and tightened in accordance with the Technical Data and
the PARU Mini is fastened properly on a mount of sufficient load bearing capacity.
The correct parts to be conveyed are present and not jammed anywhere.
Movements of the PARU Mini, in particular its useful mass and exciter mass, are not impaired.
The PARU Mini is in horizontal alignment.

The air gap is set to the nominal width.
Check the leaf springs for damage.
If none of these measures are successful, try to start the PARU Mini by adjusting the excitation
frequency. Please contact Rhein-Nadel Automation GmbH.
Q
‘We have trouble with batches of different parts to be handled.’
A
Determine the geometric deviations of the individual batches from the setpoint parts. Send the
results to Rhein-Nadel Automation GmbH and request a quotation for a tooling that is optimized for
these varying part batches with the help of simulation.
Q
‘We have noticed a defect on the PARU Mini and need spare parts. How do we get them?’
A
In principle, each component of the PARU Mini can be ordered individually, except for the spring
legs which are available only as pre-assembled units. Please contact Rhein-Nadel Automation
GmbH (www.rna.de) for your spare part requirements.
