Abstract

The invention relates to a spinning machine with at least one sensor that senses an operating state of the spinning machine and emits a signal that characterizes this operating state, and with at least one actuator to which this signal is fed and that initiates a measure in accordance with this signal, wherein at least the sensor (1 ) is connected to the actuator (3) via radio link (2). A galvanic connection between sensor and actuator is therefore not necessary.

Description

technical area

The 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 supplied and the according to specification this signal is a measure initiates.

State of the art

spinning machinery point frequently a variety of sensors, the specific operating conditions of the Feel the machine and one of these operating states or give their occurrence or absence representative signal. This signal is then transmitted via a separate signal line or over a bus system is routed to one or more actuators after proviso initiate this action-appropriate measures.

One example for Such a functional chain is a yarn breakage monitoring, which occurs when it occurs a yarn breakage means for interrupting the Luntenzufuhr activated for drafting. At the thread run is a thread breakage sensor arranged, which feels the yarn breakage and emits a signal that over a signal line is fed to a Luntenstopp device and interrupts the supply of lunches through them.

The Operative connection between each of the many yarn breakage sensors on the yarn path at each spinning station to the respective associated Luntenstopp device requires a variety of wiring. By a bus connection Although there is a reduction between several sensors and multiple actuators The required wiring is available, but it is still a galvanic connection between these components is required.

General Description of the invention

The Invention therefore had the task of transmitting to simplify the signals by switching to galvanic connection between the sensors and the actuators can be dispensed with. She solves these Task with the features mentioned in the characterizing part of the main claim.

Usually enough a radio link effective in one direction from the sensor to the actuator. In many cases However, it is also a two-track radio link from the sensor to the actuator and advantageous from the actuator to the sensor when the actuator is the mode of action of the sensor should.

The Radio communication can use any known transmission method like Zigbee, Bluetooth, WLAN or similar.

Around also to avoid wiring for the purpose of power supply is provided to at least each of the sensors with its own battery Mistake. Because actuators usually use a wiring to the provided by them affected components, this wiring can also take over the power supply of the actuators. Of course you can The actuators also be designed to be energy self-sufficient.

A self-sufficient energy supply can be achieved by the - low - required Energy of at least the sensor from light, heat, vibration, forces or the like.

Special description the invention

In the figures of the drawing are embodiments of the invention shown schematically. Show it

1 a sensor / actuator combination effective in one direction only;

2 a bidirectional sensor / actuator combination;

3 a sensor / actuator combination with multiple, only one actor acting sensors;

4 a sensor / actuator combination with multiple, only one sensor acting actuators.

The sensor / actuator combination of 1 consists of a sensor 1 that has a radio connection 2 with an actor 3 connected is.

Of the Sensor has on the one hand a sensor on, which can be influenced by an effect. In the effect can it is a force, for example. By deflecting a thread practiced Compressive force. The effect can also be the action of light, for example, to the recipient a photocell. Furthermore, the effect can be a temperature For example, a thermocouple that feels a temperature. Also other effects come into question. The feeler emits a preferably electrical signal, that of the acting Force can be proportional.

On the other hand, the sensor has a transmitter, which converts the signal emitted by the sensor into a high-frequency signal, encodes and transmits. For this purpose, the sensor is provided with a power supply not shown here, the off a battery can exist. Alternatively, the power supply can also be effected by the action of light, heat, vibration or in any other way. Because the through the radio bridge 2 distance to be overcome is small, usually 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 So transmits this signal via its radio transmitter to the actuator 3 , The actuator is corresponding 3 with a radio receiver for the signals of the sensor 1 fitted. This radio receiver decodes the signal and only sets it in via a signal line 5 transmitted signal, 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.

An example of an application of such a sensor / actuator combination is the yarn breakage monitoring on a spinning machine. It can be a sensor on the yarn path at each spinning position of the machine 1 be arranged, which for a broken yarn a radio signal to an actuator in a Luntenstoppvorrichtung this spinning station forwards and activates this to interrupt the Luntenzufuhr to this spinning station.

In the embodiment of the 2 is the radio connection 2 . 2 ' formed so two-lane, that the actuator 3 with the sensor 1 communicates. The actuator can also influence the sensor and influence its signal formation. For this purpose, the actuator also has a radio transmitter whose signal can be received and converted by the sensor also having a radio receiver.

So can e.g. in the cited Use case, the actuator give the sensor, no thread breakage signal as long as the occurred thread breakage is corrected and a thread break signal disturb this would.

It is understood that the between a sensor 1 and an actor 2 exchanged signals must be coded so that they act only on the two sensors and actuators for which they are intended.

Anendungsfälle are conceivable, according to 3 several sensors 1 only one actor 3 apply. Here, the signals of all sensors have the same, the associated actuator responsive coding.

Conversely shows 4 an arrangement in which an actuator 3 several sensors 1 applied. 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.

Due to the self-sufficient energy supply, in particular of the sensors, but also of the actuators, in addition to the signal transmission, it is also possible to dispense with wiring the sensors and / or actuators for the energy supply, which greatly simplifies their assembly, accelerates and reduces their costs. Of course, then, if for a sensor or - in particular an actuator as in the illustrated cases via the signal line 5 - Wiring is required anyway, be apart from a self-sufficient power supply.

In many cases enough a distinction of a sensor signal after yes / no. But there is also cases in which the sensor signal is proportional to the sampled state have to be. Thus, for example, a temperature-sensing, the heating of a Component or space monitoring Sensor in a first temperature range via the actuator a cooling fan turn on. In a second, higher temperature range he can turn on a warning lamp and in a third, dangerous Temperature range, he can shut off the heat-generating component initiate.

Of the The subject of the present invention is not exclusive the subject of the individual claims, but also from the combination the individual claims among themselves.

All Information and characteristics disclosed in the documents, in particular the spatial training shown in the drawings as claimed essential to the invention, as far as they individually or in Combination opposite the prior art are new.
