Basic Systems
Basic systems with electropneumatic, mechanical or
servo drives
Our flexible basic systems can be equipped with electropneumatic, mechanical
or flexible servo drives according to your assembly task.
If your task gets bigger, so will your assembly installation. In case
production quantities are increased at a later stage, a Pfuderer RTS®
Circular Transfer System or a LTS® Longitudinal Transfer System can
seamlessly be complemented with a process station of a THA® Semi-automated
Manual Workstation.
Depending on the expected production quantity, the variety of designs of
your products and the desired degree of automation we work with you in
developing the most cost-efficient solution.

RTS® Circular Transfer System
More options through our unique circular design
The selection and combination of the drives is based on quantity
requirements, number of versions and variety of parts. The assembly stations
belonging to the RTS® Circular Transfer System as well as the process
stations may be placed inside of the workpiece carrier ring.
The benefits: The best possible accessibility for operation and maintenance.
And: The improved clarity of the layout - for feeding the workpieces as much
as for arranging the decollation and alignment units. The processes are
always clearly visible and process tools may be replaced quickly and easily
from the front.

RTS® XXS
Space miracle assembles small subassemblies fully
automated and in high numbers
The positioning precision of plus/minus 0.05 millimeter and the axial
run-out accuracy makes the RTS® XXS the perfect basic system for precision
uses like ultrasonic sealing, riveting or injection molding for the plastic
and metal fitting industry. The RTS® XXS manufactures for instance fixing
elements, hinges, fittings or seals. The advantages: the RTS® XXS requires
little space, works dependably by the piece for comparably little money.
And: lithe and lissom in her size, the basic machine fits on only 1.4 square
meters. It reaches a rate of up to 120 cycles per minute and is suitable for
subassemblies of two to five building components at a yearly output of
500,000 pieces.
|
|
LTS® Longitudinal Transfer
System
More options due to two drives on each side
The longitudinal design provides clearly structured, modularly built
production lines which can be extended at any time. As with the circular
design, accessibility is provided from both sides. Assembly and process
stations may be arranged either to the left or right of the transport
direction. Valve and plug bays are installed above the assembly station and
offer very good accessibility. Thus, our concept is not only ergonomically
thought through but also offers extremely fast retooling times - one reason
for high productivity along with top quality and reliability.

Robotic Cells
The ultimate system with regard to reusability and
flexibility
Robotic cells can be operated in a highly economical and efficient manner.
This requires an intelligent arrangement of process stations and an optimal
workpiece delivery.
The parts transport is initiated by the robot itself which makes the gripper
the only workpiece-specific application. Additional workpiece receivers are
not required.
And: Due to the many options for variation the robotic cell is a very
flexible assembly centre which can easily be adapted to new requirements -
for instance when a product is changed.

THA® Semi-Auto.Manual
Workstation
Have processes and quality assurance for product
launches and limited production under control
Semi-Automated Manual Workstations may be designed for pilot productions as
well as for limited production. Due to their ingenious basic concept they
offer flexible solutions and require only a minimal effort for adaptation to
new assembly tasks. The well-proven process stations may be integrated into
RTS® and LTS® systems at a later stage without any trouble.
As a rule THA® is designed for the manual insertion and joining of parts.
The processes occur automatically and can therefore be perfected during the
pilot production phase. At the same time, quality is assured by test
stations.

Peripheral Systems
Peripheral systems for the safe supply of
workpieces
Peripheral systems offer solutions for the supply, organisation and transfer
of the processed workpieces.
Size, weight, material and condition of surface as well as your individual
requirements are essential in determining whether your workpieces are
treated as bulk or palletised material.

LFS® Linear Conveyer System
The cost-efficient alternative in feeding technology
The Linear Conveyor System LFS® by Pfuderer is an ergonomic and space-saving
alternative to conventional combinations of hoppers and spiral conveyors.
The basic machine is able to feed various parts geometries. The parts
magazine is integrated in the basic machine thus saving space; the parts in
the magazine are not subject to damaging vibrations and are treated with
care.
The linear sorting device enables straight and machine-made baffles. The
sorting devices can be documented and reproduced.
The sorting vibration can be adjusted independently from the parts feeding
rate so that very little vibration is possible. Even parts with very small
sorting attributes can be sorted. Another plus factor is the resulting low
noise level in comparison to vibrating spiral conveyors.
|
|
Palletising
Task-specific palletising for your automation
We configure palletising systems for the greatest variety of goods. As a
matter of course, these systems are tailored to suit the respective
workpieces and pallets and will treat the palletised goods with appropriate
care. The pallets can be provided on belt bands or stacked on pallet
carriages. Based on the required quantities, the workpieces will be fed into
the assembly machine directly or via a cycle belt.
|
|
PRS® Portal Robot System
Peripheral handling of your workpieces
The supply of large workpieces or packaging units is best facilitated by our
modular system made up of line gantries and face gantries. Based on the
requirements the gantries are configured to form a customised solution to
meet the highest requirements.
|
|
Profile System
Stable cross-sections for your automation
Our Pfuderer aluminium profile system is suitable for the construction of
racks, supports and protective coverings. It serves a variety of purposes
and can always be adjusted to local conditions and your specific
requirements.
|
|
|
|
Assembly Stations
The variety of assembly stations leaves nothing to
be desired
Before the feeding process your workpieces will be separated by standardised
separators or by compartment wheels. If necessary your workpieces may
subsequently be orientated in an auxiliary station and then put into the
workpiece carrier by means of linear or rotative handling units.
In accordance with the requirements for your workpieces the best handling
may be configured with standard components and individual workpiece
applications can be reduced to a minimum. Movements are carried out in the
form of vertical and horizontal assembly movements; even twofold movements
are possible.
All standard components have identical interfaces so that a station can be
used on Semi-Automated Manual Workstations THA®, LTS® Longitudinal Transfer
Systems or RTS® Circular Transfer Systems without modifications.
For very complex cases linear tappets can be used for drive elements and
mechanical elements such as reversing levers, lever transmissions, link
joints, connecting links and toothed racks/toothed wheels for your
individual construction requirements.

Process Stations
Secure and high-performance processing systems: We
help you achieve your goals the easy way
Secure processes are the foundation for quality. The point is to create a
repeatable and secure process which accurately positions the workpieces time
and again. In order to implement secure and powerful solutions as
efficiently as possible, we use only high-quality components for our process
stations.
If the market does not provide a suitable component, we will develop
individual solutions ourselves that are customised to your product and to a
safe and reliable production process. It goes without saying that the
process station controls will be integrated in the overall concept of the
installation.
|
|
|
|
Screwing
Our screw station is capable of applying the precise
torque to a variety of screws. Depending on diameter and length the screws
will either be delivered by a blower or manually positioned. Torque and
rotation angle are controlled during the screwing process which is actuated
by a highly dynamic servo motor.
|
|
Force fitting
The force fitting of parts is performed by
load-displacement controlled servo-driven insertion units. The
load-displacement path can be analysed and traced graphically.
|
|
Welding
For electric resistance welding or medium frequency
welding we buy high-quality components. Welding parameters, such as welding
current and welding duration as well as the contact pressure of the
electrodes, can be individually adjusted.
|
|
Riveting
Our first choice for riveting is the gentle and highly
reliable radial riveting method. The positioning of the riveting stations
can be vertically down from the top or from the bottom, as well as
horizontally from the front or back. If the space is small, the riveting
station can be set up retractably. The quality of the riveting is ensured by
a paralleled load-displacement measuring system or by measuring the rivet
height before and after the riveting station.
|
|
|
|
Punching
Punching is performed by high-quality tools made of fully
hardened tool steel. Thus the stations achieve a maximum service life.
Punching can be used for holing or separating material.
|
|
Greasing
For greasing we use high-quality volume dosing valves
which enable a more precise dose. A barrel pump ensures that the grease is
supplied bubble-free and is exactly positioned either point to point or
through a caterpillar-like movement of the dosing valve.
|
|
Ultrasonic sealing
For the ultrasonic sealing of plastic parts we buy
high-quality components from external sources. The optimal sonotrode and the
suitable anvil will be determined by means of process tests.
|
|
Siliconizing
Silicone is applied to the plastic parts either with a
pad or by spraying.
|
|
|
|
Measuring
For measuring we use high-quality analogue or digital
distance measuring systems. The data can be alphanumerically displayed and
statistically analysed. The measuring systems are referenced by a setting
gauge.
|
|
Optical test
For optical tests we use image processing systems with
intelligent cameras which control completeness and geometry of the
subassembly.
|
|
Tightness testing
In testing tightness we use high-quality testing
instruments with the pressure drop test or differential pressure method. The
test volume can be reduced by means of a volume displacer. The seal will be
plane or with expanding mandrel.
|
|
Marking
The parts are marked by means of a laser, a pneumatic
scriber, an indent dot marking machine or an ink-jet printer.

quantity-dependent production life cycles and product changes. Make use of
our systems' variability for your automation.
|
|
|
|
Semi-Automation
Cost-efficient start to automation
Semi-automation is the economical way of getting started with automation.
For example the feeding of the parts can still be conventional while other
processes run automatically and the quality of your production is assured by
automatic test stations. A cost-efficient solution requires no more than
100,000 units per year with semi-automation.
|
|
