Definitions

• the invention relates to a spinning machine with at least one sensor which senses an operating state of the spinning machine and emits a signal characterizing this operating state and with at least one actuator to which this signal is fed and which initiates a measure in accordance with this signal.
• Spinning machines often have a plurality of sensors which sense certain operating conditions of the machine and emit a signal representing these operating states or their occurrence or absence. This signal is then fed via a separate signal line or via a bus system to one or more actuators, which initiate appropriate measures in accordance with this signal.
• An example of such a functional chain is a yarn breakage monitoring, which activates a device for interrupting the Luntenzuschreib about the drafting system when a thread break occurs.
• a thread breakage sensor At the thread running a thread breakage sensor is arranged, which feels the thread breakage and emits a signal which is fed via a signal line of a Luntenstopp device and interrupts the Luntenzucht through this.
• the invention therefore had the task of simplifying the transmission of the signals by eliminating the need for galvanic connection between the sensors and the actuators. It solves this problem with the features mentioned in the characterizing part of the main claim.
• a radio link effective in one direction from the sensor to the actuator is sufficient.
• a two-track radio link from the sensor to the actuator and from the actuator to the sensor is advantageous if the actuator should be able to influence the operation of the sensor.
• the radio connection can use any known transmission method such as Zigbee, Bluetooth, WLAN or similar.
• actuators are usually provided with a wiring to the components influenced by them, this wiring can also take over the power supply of the actuators. Of course, however, the actuators can also be made energy self-sufficient.
• a self-sufficient energy supply can be achieved in that the - low - required energy of at least the sensor from light, heat, vibration, forces o- or the like is obtained.
• FIG. 1 shows a sensor / actuator combination which is effective in only one direction
• FIG. 2 shows a sensor / actuator combination which is effective in both directions
• FIG. 3 shows a sensor / actuator combination with a plurality of sensors acting on only one actuator
• Fig. 4 is a sensor / actuator combination with multiple, acting only a sensor actuators.
• the sensor / actuator combination of Figure 1 consists of a sensor 1, which is connected via a radio link 2 with an actuator 3.
• the senor has a sensor which can be influenced by an effect.
• the effect may be a force, for example the pressure exerted by deflecting a thread.
• the effect can also be the action of light, for example on the receiver of a light barrier.
• the effect may be a temperature, for example a thermocouple that senses a temperature. Other effects are also possible.
• the sensor emits a preferably electrical signal, which may be proportional to the applied force.
• the senor has a transmitter, which converts the signal emitted by the sensor into a high-frequency signal, encodes and transmits.
• the sensor is provided with a power supply not shown here, which may consist of a battery. Alternatively, the power supply can also be effected by the action of light, heat, vibration or in any other way. Since the distance to be crossed by the radio bridge 2 is small, typically between one and 100 m, the energy demand of the sensor is very low and can be covered by the sources mentioned.
• the sensor 1 thus transmits this signal via its radio transmitter to the actuator 3.
• the actuator 3 is equipped with a radio receiver for the signals of the sensor 1. This radio receiver decodes the signal and converts it only into a signal routed via a signal line 5, if it is determined by its coding for him. It can then initiate an action of the spinning machine or a component thereof.
• the actuator like the sensor, can be provided with a self-sufficient power supply.
• a sensor 1 can be arranged on the yarn path at each spinning position of the machine, which for a broken yarn forwards a radio signal to an actuator in a Luntenstoppvorides this spinning station and activates this to interrupt the Luntenzucht to this spinning position.
• the radio link 2, 2 ' is so two-lane that the actuator 3 is also connected to the sensor 1.
• the actuator can also influence the sensor and influence its signal formation.
• the actuator also has a radio transmitter whose signal can be received and converted by the sensor also having a radio receiver.
• the actuator give up the sensor, no yarn breakage signal to generate, as long as the occurred yarn breakage is corrected and a yarn breakage signal would interfere with this.
• FIG. 4 shows an arrangement in which an actuator 3 acts on a plurality of sensors 1. Its radio signals have a coding, by which all intended sensors are addressed.
• An application for this embodiment is, for example, then given when the signal formation of several sensors simultaneously and consistently turned off, turned on or changed.
• the actuators can be dispensed with in addition to the signal transmission and the power supply wiring of the sensors and / or actuators, which greatly simplifies their installation, accelerated and cheaper.
• a wiring is required anyway, will be apart from a self-sufficient power supply.
• a distinction between a sensor signal and yes / no is sufficient.
• the sensor signal must be proportional to the sampled state.
• a temperature-sensing the heating of a component or space monitoring sensor in a first temperature range via the actuator turn on a cooling fan. In a second, higher temperature range, he can turn on a warning lamp and in a third, dangerous temperature range, he can initiate the switching off of the heat-generating component.
