Abstract
A machine tool monitoring device includes a detection device (32) for detecting the presence of a type of material, in particular human tissue, in a machine tool area (34) via spectral evaluation of radiation (S). The detection device (32) includes a sensor unit (50) having at least one sensitivity range (64) for detecting radiation in a wavelength range (WL2) located at least partially in the infrared spectrum (72).
Claims10
A machine tool monitoring device, comprising:
- a detection device (32) for detecting the presence of a type of material, in particular human tissue, in a machine tool area (34) via spectral evaluation of radiation (S), wherein the detection device (32) includes a sensor unit (50) having at least one sensitivity range (64) for detecting radiation in a wavelength range (WL2) located at least partially in the infrared spectrum (72),
- wherein the detection device (32) includes a transmitting unit (48) which transmits radiation, a portion of which at the least is in the wavelength range (WL2), and in at least one further wavelength range (WL1, WL3, WL4), and wherein the radiation of the at least one further wavelength range (WL1) is in the ultraviolet spectral range (68), and wherein the transmitting unit (48) transmits radiation in at least one wavelength range (WL1, WL2, WL3, WL4) in a pulsed manner.
A machine tool, in the form of a cutting or sawing tool, which includes a machine tool monitoring device, said machine tool monitoring device comprising a detection device (32) for detecting the presence of a type of material, in particular human tissue, in a machine tool area (34) via spectral evaluation of radiation (S), wherein the detection device (32) includes a sensor unit (50) having at least one sensitivity range (64) for detecting radiation in a wavelength range (WL2) located at least partially in the infrared spectrum (72),
- wherein the detection device (32) includes a transmitting unit (48) which transmits radiation, a portion of which at the least is in the wavelength range (WL2) and in at least one further wavelength range (WL1, WL3, WL4), and wherein the radiation of the at least one further wavelength range (WL1) is in the ultraviolet spectral range (68),and wherein the transmitting unit (48) transmits radiation in at least one wavelength range (WL1, WL2, WL3, WL4) in a pulsed manner.
