Description

Spinning machine with sensor

The application is: March 24, application number were in 2007: 200780008087.5 (PCT/EP2007/002625), denomination of invention divide an application for the application for a patent for invention of " having the sensor of wireless connections and the spinning machine of actuator ".

Technical field

The present invention relates to a kind of spinning machine, described spinning machine has at least one sensor, and described sensor can be surveyed the running status of described spinning machine and can send the signal that characterizes this running status, and described at least sensor is self-centered aspect energy.

Background technology

Spinning machine often has a large amount of sensors, and these sensors are surveyed some running status of spinning machines, and sends and represent these running statuses or these modes of operation have taken place or the signal of these modes of operation does not take place.This signal is transported to one or more actuators by independent holding wire or by bus system, and actuator is according to suitable operation on the described signal enabling function.

An example of this functional chain is the fracture of wire supervising device, and the fracture of wire supervising device activates a device under the situation that the yarn fracture of wire occurs, so that interrupt the rove supply, for example interrupts to drafting system supply rove.Be furnished with circuit wire sensor on the thread path, this circuit wire sensor is surveyed the yarn fracture of wire and is sent signal, by holding wire this signal is provided to rove supply arresting stop, and interrupts the rove supply by this rove supply arresting stop.

In each of the many circuit wire sensors on the thread path of each spinning position to a large amount of distribution of effective connection needs of attaching troops to a unit respectively between the rove of corresponding sensor supply arresting stop.Though can reduce required distribution by the connection of the bus between a plurality of sensors and a plurality of actuator, between these members, still need to be electrically connected.

Summary of the invention

Therefore task of the present invention is, by the electrical connection of cancellation between sensor and actuator, simplifies the signal transmission.The present invention solves this task with described feature in the characteristic of main claim.

It is just enough to have the wireless connections of working on the direction under the normal condition from the sensor to the actuator.If yet actuator will influence sensor working, so under many circumstances, it also is favourable that the double-direction radio from the sensor to the actuator and from the actuator to the sensor connects.

Wireless connections can utilize known hope transmission method such as Zigbee, Bluetooth, WLAN or similar manner arbitrarily.

For avoiding carrying out distribution for the purpose of energy supply, each sensor is provided with own battery at least.Because actuator is typically provided with the distribution that leads to by the member of its influence, so this distribution also can be born the task to the actuator energy supply.Yet, it is evident that, also can construct actuator in the self-sustaining mode of power self-support.

The energy supply that can reach self-sufficiency like this promptly, can be the required less energy of sensor from light, heat, vibration, power etc. at least.

Description of drawings

Schematically show embodiments of the present invention among the figure.Among the figure:

Fig. 1 only illustrates effective sensor/actuator combination in one direction;

Fig. 2 is illustrated in effective sensor on the both direction/actuator combination;

Fig. 3 shows sensor/actuators combination, and wherein a plurality of sensors only act on an actuator;

Fig. 4 shows sensor/actuators combination, and wherein a plurality of actuators only act on a sensor.

The specific embodiment

Sensor/actuators combination shown in Figure 1 comprises sensor 1, and this sensor 1 is connected with actuator 3 by wireless connections 2.

Sensor has the detector that can be subjected to a function influence on the one hand.This effect can be power (for example passing through fibre deformation and applied pressure).This effect also can be light for example shields the recipient of device to photoelectricity effect.In addition, this effect can also be temperature (for example temperature-sensitive element of sense temperature).Also can be other effects.Detector preferably provide can with the proportional signal of telecommunication of active force.

On the other hand, sensor has transmitter, and this transmitter will be converted to high-frequency signal by the signal that detector sends, and this signal is encoded and it is sent.For this reason, sensor is provided with energy supply not shown further here, and it can comprise battery.Alternatively, the energy supply also can be passed through the effect of light, heat, vibration or otherwise realize.Because it is shorter to transmit 2 distances that cover by radio, usually between 1m-100m, so the energy demand of sensor is very low and be enough to satisfy by described source.

Sensor 1 sends to actuator 3 by its radio transmitters with this signal.Be that actuator 3 is at the signal of sensor 1 and be provided with wireless receiver accordingly.This wireless receiver decoded signal, and if this signal since its coding at this wireless receiver, then this signal just can be converted into the signal that continues transmission by holding wire 5.This can be so that the parts of spinning machine or this spinning machine start a certain operation.Actuator can be provided with self-centered energy supply as sensor.

Fracture of wire supervising device on spinning machine is the embodiment at a kind of application of this sensor/actuators combination.Here, can be on the thread path of each spinning position of machine placement sensor 1, sensor 1 under yarn fracture of wire situation with on the actuator of radio signal transmission in the rove arresting stop of this spinning position, thereby activate this rove arresting stop to interrupt rove supply to this spinning position.

In the embodiment of Fig. 2, wireless connections 2,2 ' be configured to bi-directional make actuator 3 link to each other with sensor 1.This actuator also can be exerted one's influence and influence its signal and be formed sensor.For this reason, actuator also has radio transmitters, and its signal is by the sensor reception that has wireless receiver equally and by its conversion.

Like this, for example shown in application in, just by solution and local flaw signal can disturb under the situation of its solution, actuator can not generate local flaw signal by instruction sensor at the fracture of wire that has taken place.

Obviously, between sensor 1 and actuator 3 exchange signal must encode, like this they only act on they will towards described two sensors and actuator.

Such applicable cases also can be expected, wherein, only an actuator 3 is applied effect according to a plurality of sensors 1 of Fig. 3.In this case, the signal of all the sensors all has the same-code that activates associated actuator.

In contrast, Fig. 4 shows the arrangement that one of them actuator 3 acts on a plurality of sensors 1.Its radio signal has all coding of affiliated sensor so as to activateding.For example, if also integrally cut off, connect or change the signal formation of a plurality of sensors simultaneously, the applicable cases of this embodiment to be set then.

Because particularly sensor and the self-centered energy supply of actuator in addition, thereby, and, all need not sensor and/or actuator are carried out distribution for the energy supply not only for the signal transmission, so greatly simplify and quickened its installation, and more economically.It is evident that, if, so just need not self-centered energy supply in any case all will as in the example shown, carry out distribution at sensor or particularly actuator by holding wire 5.

Under many circumstances, determine that sensor signal is just not enough for being/.But also there is certain situation will make sensor signal proportional with the state that is scanned.Like this, for example, the sensor of the heating of detecting temperature, supervision member or structure space can be opened cooling fan by actuator in first temperature range.This sensor can be connected warning light in the second higher temperature range, and this sensor can cut out the member that produces heat in the 3rd temperature range of danger.

Theme of the present invention not only comes from the theme of each claim, but also comes from the mutual combination of each claim.

All are disclosed details and feature in application material, and spatial configuration particularly illustrated in the accompanying drawings as long as they are new technical schemes in terms of existing technologies separately or with the form of combination, thinks that then they are main points of the present invention.
