1. Safety Instrution
1.1. General information
These operating and assembly instructions contain all the information required for the safe use and operation of products
in the PARU series, namely the models PARU S1 b, S1 u, S1 b wide, S1 u wide, PARU M1 b, M1 u, M1 b wide, M1 u
wide, hereinafter referred to as PARU. This document, in particular the safety instructions, must be observed by all
persons working on or with these products. In addition to the information in these operating and assembly instructions,
the accident prevention rules and regulations applicable at the place of use must also be observed.
We recommend that the operating and assembly instructions be kept at the place of use of the PARU at all times.
The risk assessment procedure used is taken from DIN EN ISO 12100:2011.
1.2. Symbols and notes
In these operating and assembly instructions there are four different signal words, three of them with a symbol. In order
of decreasing importance, these are as follows:
Danger!
This symbol indicates an imminent danger to the life and health of persons. Failure to observe these in-
structions will result in severe adverse health effects, including life-threatening injuries.
Attention!
The symbol indicates possible damage to property and/or the environment.
Note!
This symbol indicates important facts and particularly useful information.
1.3. Intended use
The intended use of PARU is the drive of toolings from Rhein-Nadel Automation GmbH in automatic continuous opera-
tion and the interaction with a downstream process that picks up the conveyed goods. The toolings are buffer or sort-
ing devices matched to the PARU and are used for the controlled feeding of bulk materials for automatic acceptance
by a downstream process (e.g. handling device or separation). Any other use or structural modification of PARU is not
considered to be in accordance with the intended use. Intended use also includes observance of these operating and
assembly instructions.
PARU may only be used with coordinated toolings from Rhein-Nadel Automation GmbH or with toolings coordinated
via the digital technologies of Rhein-Nadel Automation GmbH. Any other use is considered "not as intended". No mod-
ifications or conversions may be made to the PARU without prior consultation with the specialist personnel of Rhein-
Nadel Automation GmbH and their approval.
The area of application of PARU within the scope of the intended use is in covered and enclosed industrial production
and assembly facilities ("industrial area").
PARU may not be used:
1. outdoors
2. in wet or hazardous areas
3. under daylight
4. in areas with highly flammable media
5. in aggressive environments (e.g. saline atmosphere)
6. in production plants requiring clean room conditions
7. in private households
The limits of the PARU temperature range are set by the electromagnets installed. The ambient temperature should not
exceed 40°C and its average value over a period of 24 hours should not exceed 35°C. The lower limit for the ambient
temperature is -5°C. The altitude of the place of use shall not exceed 2000 m above sea level. The relative humidity of
the ambient air should not exceed 50% at 40°C. At lower temperatures, higher humidity may be allowed, e.g. 90% at
20°C. The ambient air should not be significantly contaminated by dust, smoke, aggressive gases and vapors. Avoid
direct sunlight or high UV radiation, as this can lead to embrittlement of some plastics that may be used in tooling and
can make it difficult to read displays.

Rhein-Nadel Automation GmbH 5
The following groups of persons ("users") are authorized to handle PARU:
1. instructed person: the instructed person has demonstrably been instructed by the operator about the tasks assigned
to him/her on the PARU and possible dangers in the event of improper behavior on the PARU. Instruction is the basic
prerequisite for working on the PARU. Reading the technical documentation of the PARU is part of the instruction.
Qualified personnel: Due to their technical training, knowledge and experience as well as knowledge of the relevant
standards and regulations, qualified personnel are able to carry out the assigned work on the PARU and to independently
recognize possible hazards when handling the PARU and to avoid hazards. A qualified electrician who, due to his
technical training, knowledge and experience as well as knowledge of the relevant standards and regulations, is able to
carry out work on the electrical components of the PARU and to recognize and avoid possible hazards independently.

2. Product description
2.1. General information
PARU is a standardized platform for the correct, individual supply of bulk materials in automated production or assembly.
PARU is used in particular for buffering conveyed goods that have already been correctly oriented via ROTU. For this
purpose, PARU is equipped with a material-specific tooling and integrated into the operator's production or assembly
line, either on its own or as part of a feed system. PARU is thus an incomplete machine in the sense of the EC Machinery
Directive 2006/42/EC.
With new toolings from Rhein-Nadel Automation GmbH, PARU can be converted at any time to feed new materials. The
toolings are supplied by Rhein-Nadel Automation GmbH with information on the optimum amplitude, frequency and, if
necessary, compressed air settings. No adaptation of the drive is necessary. PARU thus offers flexible feeding of con-
veyed goods at high conveying rates and short changeover times.
Note!
PARU is a precision machine. The functionality of the toolings depends on accuracy of the topology to the
tenth of a millimeter. The settings on the control unit, the condition of the conveyed goods and the quality
of the screw connections must also correspond to the condition of the specifications for target-oriented
function.

2.3. Description of functions
PARU is a dual-mass oscillator. In PARU, the counter mass and the effective mass are connected to each other via
obliquely set leaf springs with a fixed, non-adjustable angle. Vibrating magnets excite the system. This results in an
oscillating movement of the working mass and the tooling. Due to this movement, the conveyed goods are accelerated
in horizontal and vertical direction and move along the tooling. PARU oscillates in the range of 100Hz, the amplitude in
vertical direction is up to 20µm, the amplitude in horizontal direction is up to 80µm.
Figures 1 and 2 show PARU without tooling. The tooling is fastened to the effective mass via the grooves of the effective
mass by means of M6 nuts. Figure 4 shows a PARU S1, b with an exemplary tooling shown in green.
The conveyed goods are finally aligned and buffered, if necessary, via the tooling and the conveyed goods-specific
arrangement elements. The tooling includes a carrier plate (1), which is fixed to the aluminum profile of the useful mass
by means of screws (2) ISO 4762, M6x25, strength class 12.9 and sliding blocks. The sorting elements (3), in turn, are
fixed to the carrier plate by means of clamping claws and screws (4) ISO 4762, M5x25, strength class 12.9. The strain
relief for the cable of the electrical supply of the vibrating solenoid(s) (5) is located on the bottom side of the
counterweight. PARU is screwed to the installation site via the threaded holes of the rubber feet (6).

3. Mounting Instructions
3.1. Transportation
PARU is packed for transport in a wooden crate suitable for the requirements or secured on a Euro pallet. You will
need suitable lifting gear to transport PARU to its place of use. If the wooden crate/Europallet is badly damaged on
delivery, please contact the carrier immediately. In order not to lose the right to claim settlement due to formal errors,
please take into account the general terms and conditions of the forwarding agent.
PARU is fixed to the base plate of the wooden crate/Euro pallet. When unpacking and transporting, please observe
any instruction leaflets supplied. We recommend that you keep the transport crate/Europallet and the packaging mate-
rial for returning your PARU.
Unless otherwise agreed, the scope of delivery of the PARU includes:
1. transport crate/Europallet
2. PARU
3. operating and installation instructions
4. installation declaration
5. Tooling or tooling sets with setting recommendations, if applicable
Attention!
PARU must not be lifted or transported by the tooling. Before transporting, make sure that the lifting gear
used has sufficient load-bearing capacity for the PARU. During transport, no persons may be under the
PARU.
3.2. Assembly
PARU is delivered completely assembled, so that you only have to unpack PARU and assemble it at the destination.
After removing the PARU from the wooden crate/Euro pallet, you should first check the visible surfaces of the PARU
and, if necessary, clean them to remove any contamination that may have entered the PARU during transport. If neces-
sary, please refer to the enclosed instructions for any adjustment and assembly work agreed individually with the cus-
tomer.
Attention!
When placing the PARU on the target substructure, the temporary parking area or the target machine into
which PARU is to be integrated, sufficient load-bearing capacity must be ensured. The target location must
be dimensioned in such a way that no vibrations from the machine can be transmitted to the PARU or no
vibrations from the PARU can be transmitted to the target machine.
PARU is screwed to the stand frame provided by the user or to a machine frame of the complete machine via the M6
threaded holes on the underside of the rubber feet. It is recommended that all rubber feet be bolted with ISO4762 M6
bolts of strength 8.8, Loctite threadlocker and a tightening torque of 10Nm.
Make sure that the components of the PARU that are subject to vibration cannot touch other devices during operation.
3.3. Bringing into service
Note!
The transfer of the workpiece provided via PARU tooling must be secured by the customer.
Before switching on for the first time:
Before switching on the PARU for the first time, check that
•The effective mass of the PARU can be moved freely without hitting the counter mass or components of the
installation site.
•PARU is properly bolted to the target location and aligned using a spirit level
•The tooling is bolted down to the torque specified in the technical data.
•There are no objects or conveyed goods in the PARU.
•The available power supply (frequency, voltage, power) corresponds to the connection data of the control unit
used.
•The control unit settings have been made in accordance with the specifications to match the tooling.
•The connection cable of the PARU is plugged into the respective control unit and the protective earth conductor
is connected.
•If compressed air is used for sorting, the compressed air supply is connected.

Rhein-Nadel Automation GmbH 9
Attention!
It must be ensured that the machine frame (stand, base frame, etc.) is connected to the protective earth
conductor (PE). If necessary, a protective grounding must be carried out on site.
The electrical connection of the PARU and the components as well as the commissioning of the PARU may only be
carried out by qualified personnel in accordance with the national provisions and regulations of the country in which the
PARU is operated. When making changes to the electrical connection, be sure to observe the operating instructions for
the control unit used.
Since PARU is a partly completed machine, the interaction between PARU and the user's acceptance station must be
evaluated by the customer in a risk analysis. If measures are necessary as a result of this risk analysis, they must be
implemented by the user. Emergency stop switches are not provided on the PARU. This function must be implemented
by the manufacturer of the overall system/machine. Access to the circuit breakers must be free of obstacles at all times.
The proper function of the off switches must be checked daily at the start of machine operation.
Attention!
PARU must not be put into operation until it has been completed with the complete machine and the safety
requirements of the EC Machinery Directive for the complete machine have been met.
The first switch on:
After carrying out the previous steps, PARU is switched on without workpieces and at a low amplitude (start value e.g.
10%). The amplitude is now increased step by step to the target value for the tooling. The effective and counter masses
of PARU must not strike anywhere.
If loud noises are noticeable on the PARU when it is switched on for the first time, please check whether
- All screw connections have been made in accordance with the technical data.
- The magnetic gap is correctly set at 3 mm or lower.
- The transition to the ROTU, to the separation or into the mold is correctly set.
If this is not the case, please contact Rhein-Nadel Automation GmbH.
Note!
The optimum conveying capacity of the PARU for one or more of the customer's conveyed goods has
already been determined at the Rhein-Nadel Automation GmbH factory. We recommend not to deviate from
the default values of amplitude and frequency for the corresponding tooling.
If PARU runs smoothly at the target frequency and amplitude associated with the tooling, the upstream process (feed
system, e.g. ROTU) can be started with conveyed goods and the transition to PARU can be finally coordinated.
4. Operation Instructions
4.1. Operation
The following points must be observed when operating the PARU:
1. the feeder is switched on or off via the control unit as standard. The user is free to connect this control unit in turn to
his higher-level machine control system.
2) A backlog of workpieces in the tooling of the upstream feed system, e.g. ROTU, must be avoided in any case, e.g.
by shutting down the feed system or ROTU on the control unit side.
When using compressed air at the tooling, the operating pressure must be kept constant and must not be switched off
during operation. When switching on or restarting, ensure that the operating pressure is safely present before PARU
starts. 4.
The set air and sorting nozzles must not be changed. 5.
Accessibility to the PARU must be ensured for the operating personnel. 6.
6. jammed workpieces may only be removed from the PARU if it has been switched off completely beforehand. This
procedure must be carried out without destroying the workpiece and the tooling! PARU is a precision machine; damage
to the tooling in the range of tenths of a millimeter can already result in functional impairments. 7.
If the information in these operating and assembly instructions is observed, PARU is maintenance-free.
Note!
PARU may only be operated by trained specialist personnel. The information in these operating and as-
sembly instructions must always be observed. The operating personnel of the operator of the PARU can be
trained by Rhein-Nadel Automation GmbH. Please ask for the conditions for such a training measure if
required.

Rhein-Nadel Automation GmbH 10
Note!
Depending on the material being conveyed, the PARU can be very noisy. The use of ear protectors is
therefore recommended for work on and in the vicinity of the PARU.
Attention!
It should not be assumed that the stopped PARU is a safe device. Spent energy from the leaf springs can
be released unintentionally or through improper maintenance procedures. This applies in particular to pro-
cedures which can be dangerous if carried out contrary to the recommendations of these assembly instruc-
tions while the machine is in operation, e.g. removal of a jam.
4.2. Tooling changeover
The following points must be observed when changing the tooling of the PARU:
1. switch off the PARU, switch off the compressed air supply. 2.
2. loosen the tooling segments fastened with clamping claws. The carrier plate remains on the PARU. 3.
If necessary, disconnect existing compressed air connections. 4.
4. store the old tooling at the designated storage location which meets the requirements of Chapter 5 of these Operating
and Assembly Instructions.
5. carrying out the rapid emptying and the setup procedure of the upstream feed system, e.g. ROTU, for the complete
removal of the old conveyed goods
6. assembly of the new tooling on the PARU. Make sure that the transition to the upstream and downstream process is
adjusted accurately.
7. feeding of the conveyed goods into the upstream process. Operation of the PARU according to chapter 4.1 of these
operating and assembly instructions
Note!
When changing the tooling, make sure that the upstream process (feed system or ROTU) supplies the
correct materials to the new tooling of the PARU in order to avoid damage caused by incorrect materials.
4.3. Maintenance intervals and time limits
PARU is designed for automatic continuous operation. Information on the wear of the tooling cannot be given, as this
varies depending on the PARU system - tooling - material conveyed. The recommended maintenance intervals are as
follows:
1. daily: visual inspection of the PARU for jammed conveyed goods or damaged elements
2. weekly or as required: cleaning of PARU and tooling
3. semi-annually: basic cleaning of the PARU
The following agents are recommended for cleaning:
