SAFETY GATE SYSTEM AND SAFE
INTERLOCKING FOR A CORE CUTTER
When drives cause movement in machines and heavy rollers and
blades rotate, there are multiple hazards that must be guarded against.
As Brodbeck, a Swabian machine manufacturer, knows, it is not
products alone that make machines safe, productive and easy to
operate; integrated automation and safety solutions are required. That
is why this special purpose machinery manufacturer has relied on
automation solutions from Pilz for many years: in conjunction with the
configurable safety controller PNOZmulti 2, the safety gate system
PSENmlock and the coded safety switch PSENcode are used as a
universal solution for almost all machine models.
Redesign requires a modern safety concept.
As part of a redesign of a cardboard tube cutting machine, Brodbeck
needed to modernize the control system and electronics, and
implement a new safety solution.
The cardboard tube, which weighs approximately 50 kilograms and
has an outside diameter of 750 mm and a length of around two meters,
rotates on a driven mandrel. Two external guide rollers support the
drive movement, ensuring vibration-free rotation and stability. From a
horizontally movable lower bed carriage, a rotating circular blade
descends onto the cardboard tube. The cutting tool splits the sleeve
into handy sections with predefined widths at one-second intervals. An
ejector pushes the individual rings from the mandrel into the provided
container.
PSENMLOCK: INTERLOCK AND SAFE GUARD LOCKING IN ONE
DEVICE
With many drives, rotating cardboard tubes, guide rollers and a
circular knife it is necessary to cover a whole set of hazard risks.

Brodbeck, the machine builder, counts on reproducible automation
solutions from Pilz. Together with Pilz, Brodbeck focuses on solutions for
customers, not machines.
Brodbeck attaches great importance to integrated automation and
safety solutions that make machines safe, productive and easy to
operate. For reasons of efficiency and costs, the selected control, safety
gate solutions and switch types must be suitable for use in several
machine types.
That's why today you will find the versatile configurable control
system PNOZmulti 2 in conjunction with the safety gate system
PSENmlock and the coded safety switch PSENcode from Pilz not only in
retrofit plants, but also in other machines.
