The Customer:
Geberit is European market leader in sanitary systems. The
Geberit Group currently employs 5200 people and has subsidiaries
and offices in 40 countries. Geberit's product range falls into two
groups: sanitary systems and drainage systems. At its production
plant in Jona, Geberit runs an injection moulding operation
producing elements for its Silent building drainage system.
The Task:
Produce and package different fittings
The Problem:
Achieving maximum automation in an extremely tight space
The Solution:
KraussMaffei solved the problem with an unusual approach. System
components such as the lift and conveyor belts are on castors and
can be moved out of the way for maintenance work. The sprue chute
is located where you would normally expect to find the machine's
control cabinet.
The Outcome:
The fully automated manufacturing cell, designed and built by
KraussMaffei incorporates a KM 800-12000 MX injection moulding
machine and a LR 300 linear robot. The system is designed for easy
switchover between different products: depending on the order
situation, curved or branching pipe fittings can be produced. The
linear robot demolds parts and presents them for sprue cutting. The
fittings are then passed to a cooling station. At the end of a
defined cooling time, the robot deposits the fittings on a conveyor
belt. If the system is producing curved fittings, they are
transported to a filling station and packed into bags. The operator
monitors the number of units by weighing. Branching fittings are
packed in cardboard boxes rather than bags. In this case, empty
boxes are transported into the robot's field of action on a
conveyor belt. The robot then stacks the fittings directly in the
boxes - after previously labelling them. A lift moves the full
boxes down to another conveyor which transports them away from the
production area. In addition to a space-saving design for the
automation solution, it was also essential to ensure easy access to
the machine and the mould. KraussMaffei has the expertise and
experience in both injection moulding and in factory automation to
develop high-performance, application-specific solutions such as
the manufacturing cell supplied to Geberit. The system we supplied
meets all the customer's criteria for reliability, high product
quality, minimal labour input and a small footprint.
