A rotation path of the test component is at least within a sensing area of the noncontact speed sensor, the noncontact speed sensor and the electromagnetic valve are respectively electrically connected with the data processing unit, circuit structures among the noncontact speed sensor, the electromagnetic valve and the data processing unit lead the data processing unit to control switching of the electromagnetic valve according to sensed signals of the noncontact speed sensor, and accordingly failure rate of the automatic dust collection device is reduced since a pull-rod switch of a traditional automatic dust collection device is omitted.
Description
Technical field
The utility model relates to a kind of dust collect plant and switch thereof.
Background technology
The automatic dust collection device of a large amount of overlock machines that use adopts foot-operated pull-rod operator to control air valve at present, thus the collection work of control cloth waste material, but this control mode is a mechanical control method, has the high problem of fault rate.
The utility model content
The purpose of this utility model is to provide a kind of overlock machine dust collect plant and switch thereof, with the pull-rod operator of cancellation automatic dust collection device, to reduce the fault rate of automatic dust collection device.
Switch for the overlock machine dust collect plant of realizing described purpose, be characterized in that this switch comprises the test block that is arranged on the overlock machine impeller, be arranged on the contactless tachogenerator of overlock machine fixed position, data processing unit and electromagnetic valve, the rotation path of test block is in the sensing region of contactless tachogenerator at least, contactless tachogenerator, electromagnetic valve is electrically connected with data processing unit respectively, and contactless tachogenerator, electromagnetic valve, circuit configurations between the data processing unit makes data processing unit control the switching of electromagnetic valve according to the sensing signal of contactless tachogenerator.
For realizing the overlock machine dust collect plant of described purpose, comprise switch, be characterized in that this switch comprises the test block that is arranged on the overlock machine impeller, be arranged on the contactless tachogenerator of overlock machine fixed position, data processing unit and electromagnetic valve, the rotation path of test block is in the sensing region of contactless tachogenerator at least, contactless tachogenerator, electromagnetic valve is electrically connected with data processing unit respectively, and contactless tachogenerator, electromagnetic valve, circuit configurations between the data processing unit makes data processing unit according to the switching of the sensing signal of contactless tachogenerator control electromagnetic valve, on this electromagnetic valve and this overlock machine impeller by identical means of power.
Described test block is one or more magnets.
Described noncontacting proximity sensor is a Hall element.
Described overlock machine fixed position is the overlock machine fixed housing.
Described switch also comprises indicator lamp, this indicator lamp is electrically connected data processing unit, and the circuit configurations between contactless tachogenerator, data processing unit, the indicator lamp makes data processing unit control the switching of indicator lamp according to the sensing signal of contactless tachogenerator.
The beneficial effects of the utility model are:
Data processing unit can be set like this, and when sensor had signal, corresponding indicator lamp will be bright, and no signal is just gone out, and points out the no-float between test block and the sensor; Also can in data processing unit, set the rotating speed of certain rotating speed as the overlock machine normal rotation, when data processing unit judges that according to the signal of sensor overlock machine speed crosses when being lower than rated speed, close electromagnetic valve, integrating device does not need air-breathing so does not start, when processing unit judges that according to the signal of sensor overlock machine speed is higher than the setting rotating speed, data processing unit control electromagnetic valve is opened, begin air-breathing, on this electromagnetic valve and this overlock machine impeller by identical means of power, the overlock machine stall, electromagnetic valve has also cut out, air-breathing action is followed the work of overlock machine and is worked, and the generation of sort signal do not have machinery contact, the life-span is semipermanent, because the quality of electromagnetic valve is very reliable, thereby whole getter device is very reliable.
Description of drawings
Fig. 1 is the logic diagram of the switch of overlock machine dust collect plant.
Fig. 2 is the schematic diagram of structure of the switch of overlock machine dust collect plant.
The specific embodiment
Overlock machine has a handwheel, there is an impeller 23 back of handwheel, be the rotatable parts of overlock machine, one or more magnets 22 are installed on impeller 23, and Hall element 21 is installed on the fixed housing of overlock machine, Hall element 21 is electrically connected with data processing unit 13, and data processing unit 13 can be that general electronic circuit also can adopt microprocessor.Overlock machine is in case rotate, and magnet 22 and then rotates, and in a single day magnet 22 forwards Hall element 21 places to, and Hall element 21 will induced signal, and corresponding umber of pulse also just appears in what of the speed of wheel speed on Hall element 21.In data processing unit 13, set certain rotating speed and judge whether normal rotation of overlock machine, because the rotation on the sometimes artificial handwheel, also induced signal can occur on the Hall element, the be far from speed of the normal revolution of overlock machine of the speed of people's rotation is big in fact.Indicator lamp 11 and data processing unit 13 is electrically connected, and when Hall element had signal, data processing unit 13 just controlled that corresponding indicator lamp is bright, and no signal is just gone out, and points out no-float between magnet and the Hall element with this.Cross when low when processing unit 13 judgement speed, for example be less than or equal to 2 revolutions per seconds, close electromagnetic valve 14 this moment, do not need air-breathingly, and when processing unit judged that speed is high, for example greater than 2 revolutions per seconds, processing unit 13 control electromagnetic valves 14 were opened, and begin air-breathing.The impeller of overlock machine can be by identical power supply power supply with switch, so the overlock machine stall, electromagnetic valve has also cut out, air-breathing action is to follow the work of overlock machine, and the generation of sort signal does not have the contact of machinery, life-span is semipermanent, because the quality of electromagnetic valve is very reliable, thereby whole getter device is very reliable.
