Side-Entry Robots
KraussMaffei’s range of SR side-entry robots are the answer for systems capable of total cycle times under four seconds. Side-entry robots are ideal for demoulding thin-walled articles and medical products and in other fast-cycling applications.
Concept
SR series robots are engineered on a
modular basis. They can demold parts from single-cavity
or stack moulds. They are key components in solutions
for high speed in-mould labelling applications.
KraussMaffei offers standardized IML applications for a
range of products, including lids and containers. We
offer you a decisive benefit: as a system partner, we
work closely with you to provide you with the best
system solution possible – the machine, the process
engineering and the robot.
SR series side entry robots are
engineered to team up optimally with small and
medium-sized injection moulding machines.

An SR can be configured for standard
demoulding or for in-mould labelling:

Standalone robot cell -
harmonized system. The standardized KraussMaffei
robot cells include all the components required for
high-speed demoulding – a side-entry robot installed
on a rugged steel frame with a conveyor belt and a
“butterfly” station for handshake transfer of the
demoulded parts. IML cells are also equipped with
label magazines and ionization units. Positioning of
the cell is next to the injection moulding machine,
aligned with the mould midline. Cells can be
transported easily using a factory truck or a crane.

Installing the side entry
robot on a console installed on the fixed platen of
the injection moulding machine is a straightforward
solution. |
Technology
Basic robot:
The engineering brief put high
priority on bending and torsional stiffness. This
design, together with high-performance servomotors,
makes it possible to achieve extremely fast demoulding
and very short cycle times. This means the SR is ideal
for production systems making thin-walled articles. In
low-ceilinged production areas, the SR is a genuine
alternative for demoulding.

Cleanroom applications:
The SR is ideal for cleanroom
applications. Integrating the power supply lines up to
the point of gripper interface has eliminated loose
cables and tubing. The valve terminal is integrated into
the basic robot. Instead of the venturi principle
offered in the standard version, the SR can be fitted
with a vacuum pump to supply the necessary media without
causing any air turbulence. The same applies to the
cooling system. A water-cooled drive instead of a
separate fan will reduce air turbulence. Advantage for
cleanroom production cells: the laminar flow box can
simply be installed above the cell.
Control system:
Flexibility is a high priority here.
You know your own requirements best, so we offer you the
choice of integrated or standalone control systems.
Integrated control means that the KraussMaffei control
system, using bus technology, is the communication
interface between the injection moulding machine and the
integrated side-entry robot. Fast data communication
saves time and the system gives you the option of saving
data from the injection machine and the robot in one
data record – it’s convenient and secure. The
alternative is a standalone SR-S robot. Standalone
robots are mainly used to retrofit already installed
KraussMaffei injection moulding machines, to robotize
machines from other manufacturers or to maintain the
flexibility of your production. Whichever control
concept you choose, it will always be based on
KraussMaffei’s tried-and-tested MC5 control system. Our
priorities in developing the systems were
self-explanatory programming, using our programming
software, this task can be done online of offline,
simple production start-up and intuitive operation.
Benefits for customers
- Extremely short cycle times:
dry cycle time with an SR side-entry robot is under
0.4 s.
- High payloads based on
extremely high speeds and acceleration.
- The slim basic design means
that an SR can operate with very brief mould opening
times. This contributes to the very short total
cycle times that offer enormous potential for
savings.
- Highly flexible, the SR can be
used with different mould designs: single- and
multi-cavity moulds.
- A simple operating concept, a
proven control system and the choice of an
integrated or stand-alone version.
- You get a complete
manufacturing cell where all components – machine,
robot and peripherals – are guaranteed to work
perfectly together.
- IML cells as complete turnkey
systems from a single supplier
