Abstract
The invention relates to a machine tool monitoring device with an identification unity for identifying the operating situation of a machine tool. According to the invention, the machine tool monitoring device has at least one projection unit for defining at least one region to be monitored.
Claims21
A machine tool monitoring device, comprising:
- an identification unit for identifying an operating situation of a machine tool, the identification unit including at least one UWB radar sensor configured to determine position and/or speed of at least one of a human tissue and/or an animal tissue;
- and
- at least one optical projection unit for defining at least one region to be monitored, wherein the at least one region to be monitored by the at least one optical projection unit marks at least one region to be monitored by the identification unit, wherein at least one region to be monitored by the at least one projection unit has an optical appearance, the at least one optical projection unit comprises:
- a laser unit which projects a laser light, wherein if at least one of:
- a human tissue;
- and an animal tissue enters into said at least one region to be monitored, wherein the laser light changes at least one of color and light intensity resulting in a change in the optical appearance.
3 more elements
A method of monitoring a machine tool, the method comprising:
- monitoring at least one optical region defined by at least one optical projection unit;
- and
- identifying an operating situation during an operating process of the machine tool using an identification unit including at least one UWB radar sensor configured to determine position and/or speed of at least one of a human tissue and/or an animal tissue within the at least one optical region to be monitored by a laser light, wherein at least one region to be monitored by the at least one projection unit has an optical appearance, wherein the optical appearance changes if at least one of:
- a human tissue;
- and an animal tissue enters into said at least one region to be monitored, and wherein a change in the optical appearance results from a change in at least one of:
- a color and an intensity of the laser light.
