Safety: Safety concept according to the BG RCI checklist for
protective devices for the roll gap on old rolling mills (small
rolling mills D < 400 mm) of the rubber and plastics industry (current
version of 18.10.2018):
• Mechanically operated protective device with proximity reaction in
the form of a NEW safety cage over the roll gap
• Aluminium side panels; Stainless steel front flaps
• Two-piece, moving side plates with sheet metal to cover the gap
between the two plates
• Cage can be folded on both sides (monitored with magnetically
coded limit switches), incl. additional gas pressure dampers
• Safety edges (on both sides) for upper roll gap
• Safety edges at the bottom (both sides)
• When the emergency stop is activated, the rollers stop (rollers
run < 60°) and the rollers move apart (max. 50 mm)
• Design of the brake as a redundant safety function according to
PLr = d, category 3 of EN ISO 13849-1:2008.
In the first stage, the rollers are stopped electrically by the
frequency converter and in the second stage by a spring-loaded brake
on each motor-gearbox unit.
• Additional knee shift plates front and rear
Control: Control elements housed in the machine frame to save space
(no separate control cabinet required);
power unit for hydraulic power unit; Service socket
- Siemens SIMATIC S7-1511 F safety controller with digital and analog
input and output cards
- All safety functions via Siemens S7 safety PLC
- Simple, user-friendly operation via conventional hardware buttons in
the control panel
