Loading The Workpiece Pallet; Ambient Infl Uences - Bosch Rexroth PE 2 Montageanleitung

9.1.3

Loading the workpiece pallet

When setting up and testing the modular units, the workpieces pallets should not
all have the same weight on the conveyor sections. Full and empty pallets should all
come through the circuit.
Extreme differences in weight may, however, require special measures to avoid
functional disruptions. This applies to:
• Permissible accumulation length before stop gates.
• Damper function.
• Dampened stop gates.
9.1.4 Ambient infl uences
• Resistant to many common media used in production such as water, mineral oil,
grease, and detergents. Contact your Rexroth representative if you have any doubts
about resistance to specifi c chemicals, such as test oil, doped oils, aggressive
detergents, solvents, or brake fl uid.
• Avoid long-term contact with strong acidic or basic reacting materials.
• Wear may increase dramatically if the system is contaminated due to environmental
factors, particularly with abrasive media such as sand and silicates, but also due to
processes running on the transfer system (e.g. welding beads, pumice dust, glass
shards, shavings, or lost parts...). In such cases, maintenance intervals must be
substantially shortened.
• Resistance to media and contamination does not mean that functional safety is
guaranteed in every case.
– Liquids that thicken on evaporation and are highly viscous or adhesive (sticky)
could lead to a disruption in function.
– Media with lubricating properties may reduce the driving power that is caused by
friction if they are carried over onto systems with rollers.
Such cases require special attention when planning the system and the
maintenance intervals need to be shortened accordingly.
