Crushing Impacting Pulling Cutting

Exhausting of system sections

In Module 3 the motions of the drives in the cutting station represent a hazard for the machine operators.

Safety function “safe exhausting� as an integrated solution: pre-assembled valve manifold modules exhaust safety-critical areas of the system after an emergency stop.

occur in various operating modes. Once all design measures have been exhausted, it is the job of the designer to implement technical protective measures (safety functions). These are always implemented in a similar way, i.e. using a sensor, logic components and outputs.

Stopping, holding, blocking a movement

Module 4: Vertical motion on a production line often presents a risk of crushing for machine operators.

Cutting station in the model installation Within the cutting station, coated plastic sheets are cut into individual workpieces, which are then separated. The operator inputs the size of the pieces to be cut and a cutter blade on the XY gantry cuts the material accordingly. This work step represents two potential hazards: cuts and impacts. Firstly, the machine operator could be injured by the cutter blade as it rapidly moves back and forth; secondly, the moving XY gantry could lead to impact injuries on the hands, arms and upper body. The job of the designer is therefore to define suitable safety functions and implement these with the help of EN ISO 13849-1.
