Abstract
A suction-air system of a textile machine, especially a rotor spinning machine, has at least one suction-air conduit, at least one spark sensor for detecting flying sparks within a measuring extent of the suction-air, the sensor including a measuring device with a sensing range at least partially overlapping the measuring extent, at least one electromagnetic wave receiver for generating an output signal when a spark enters the sensing range, and a driver and evaluation circuit for the measuring device. At least one source for generating electromagnetic waves is associated with the receiver and actuates a purposeful initiation of the spark sensor.
Claims20
A suction-air system of a textile machine, comprising at least one suction-air conduit, at least one spark sensor for detecting flying sparks within a measuring extent of the suction-air system, the sensor comprising a measuring device having a sensing range overlapping at least partially the measuring extent, at least one receiver of electromagnetic waves adapted for generating an output signal when a spark enters the sensing range of the measuring device, a driver and evaluation circuit for the measuring device, and at least one source for generating electromagnetic waves associated with the at least one electromagnetic wave receiver, the at least one electromagnetic wave generating source being operable for purposefully initiating the spark sensor.
