Safety device for a handling apparatus, in particular an industrial robot, and method for operating the safety device

摘要

A safety device is described for a handling apparatus, particularly an industrial robot, having at least one movable gripping arm and a gripping device situated on the gripping arm, as well as having a first sensor device, connected to a control device, that is associated with the gripping arm, for collision detection. The first sensor device includes a first recording range. The safety device includes a second sensor device connected to the control device and including a second recording range. The second recording range records a range which has a greater distance from the handling apparatus than the first recording range. Both recording ranges extend outside the handling apparatus.

主权项

1. A safety device for a handling apparatus that includes at least one movable gripping arm, comprising:
a control device; a first sensor device connected to a control device and associated with the gripping arm for collision detection, the first sensor device having a first recording range starting from the handling apparatus and ending at a first recording range end position remote from the handling apparatus; and a second sensor device connected to the control device and having a second recording range starting from a second recording range starting position remote from the handling apparatus and ending at a second recording range end position remote from the handling apparatus, wherein the second recording range starting position is locatable, along a direction from the handling apparatus that is the same as a direction of the first recording range from the handling apparatus, at a location that is further removed from the handling apparatus than the first recording range end position for all operating positions of the handling apparatus.
