Next MIRS
MIRS is an integrated, modular robotic system for making
tyres. It has a very high degree of flexibility due to its ability to
optimise modularity and logistics.
In the MIRS process, tyres are fabricated around a heated
drum that is tailor-made for a particular tyre model. The drum is
continuously rotated by a robot under an extrusion device that
distributes rubber over the surface. The drum rotation and compound
feeding movements are coordinated to provide the correct
distribution of materials to create the specific tyre model.
Compared to traditional, large-scale tyre-building systems with
their exceptionally high production rates, designed for customers
in different geographic locations, the MIRS is a compact production
“island,” flexible and easily programmable for extremely
rapid adaptation to the production of new models. This system
represents a real improvement, in terms of both technology and
logistics, as it can be easily located near the manufacturing process
that it serves.
The use of robotics in the production process makes it possible to
realise extremely high product quality, due to the geometric distribution
of the rubber fibres that is constant for each model.
The CCM process
The CCM process for producing compounds uses a 100% computer
controlled pneumatic distribution system to transport the ingredients
from their storage silos to the continuously operating
twin-screw extruders.
The CCM technology was designed to manage the complexity
of the process deriving from the large number of ingredients required
to produce the compound. The computer controlled process
improves the quality of the produced compound, and consequently
the quality of the finished product.
By means of a specially designed powder capture and recycling
system for solid materials, CCM technology has reduced dust levels
in production areas to extremely low levels. The CCM process
also saves energy, enabling a reduction of approximately 20% in
energy consumption per unit of product.
The TSM process
TSM (Twin Screw Mixing) is the new process for preparation of
compounds that offers high levels of quality, reliability and efficiency,
developed specifically for the production of compounds
used in the new Pirelli green tyres.
This technology makes it possible to realise major improvements
in terms of compound uniformity, reduced dispersal of ingredients
and a 30% reduction in energy consumption as compared
with traditional techniques.
