Contact protection for processing machine, has safety elements coupled to electronic evaluation circuit and sensor(s) on each burner carriage to protect against collisions of carriages

摘要

The arrangement consists essentially of a bridge (2) movable in the X axis with a tool for insertion in the Y or Z axis, safety elements coupled to an electronic evaluation circuit and at least one sensor (4) mounted on each burner carriage (6) to protect against collisions of carriages with each other and a workpiece and for setting the distances between carriages. The analogue sensor can be ultrasonic, capacitive or inductive. Independent claims are also included for the following: a processing machine.
