A button and a light emitting diode display hole are arranged on the switch cover. The utility model has the advantages of high reliability, energy saving, no noise, sensitivity and no contact, and the motor of the loom can be automatically stopped when broken warp, lack of weft and caused defect happen. The utility model can be used in looms.
Description
The utility model relates to the loom battery-conserving switch, the loom battery-conserving switch on the loom that is used for multiple models such as 1511,1515 of more clearly saying so.
Textile industry is in the operation of weaving cotton cloth, and owing to reasons such as cracked ends, crapand, fabric defects, loom can quit work automatically.But the drive motors of loom causes equipment attrition and waste of electric energy still in dry run at this moment.If the loom parking rate calculates by 15%, every loom is spent because of dry run power consumption 1.5 every day at least, in addition, and A.C. contactor many power consumptions 0.7 degree every day of every loom, the dry run of drive motors has also reduced the service life of equipment, has increased maintenance cost.
The purpose of the utility model loom battery-conserving switch is to overcome above-mentioned shortcoming and defect, provide a kind of can when cracked ends, crapand, fabric defect take place loom and the equal automatic stopping of drive motors thereof, thereby saves energy greatly; And noiseless, contactless, no temperature rise again, delay function is arranged, drive motors there are decompression, under-voltage protection performance, voltage change there is big accommodation, control reliable, sensitive loom battery-conserving switch.
In order to achieve the above object, the utility model loom battery-conserving switch by switch enclosure, be installed in electronic circuit in the switch enclosure, be installed in the connector assembly that the switch enclosure side connects electronic circuit and loom electrical equipment, the switch cover that is fixed on the switch enclosure with securing member is constituted.Electronic circuit is by forming with the controllable silicon AC-DC switch of thyristor gating circuit control with the inductance type oscillating circuit of lever on the loom or the approaching control of other metal parts, with the thyristor gating circuit that the inductance type oscillating circuit triggers.Two induction coils in the inductance type oscillating circuit and magnetic jar thereof are installed in forms proximity transducer in the box body, proximity transducer is arranged separately on the loom, links to each other with the other parts of electronic circuit with the plug special seat that is installed in the switch enclosure side with lead.The demonstration hole that stops with starting button and light emitting diode is installed on the switch cover.
The inductance type oscillating circuit is made up of transistor, two induction coils and electric capacity.Wherein two induction coils are contained in the magnetic jar, then are installed in together to form proximity transducer in the box body.Thyristor gating circuit is made up of transistor, electric capacity, resistance etc.The controllable silicon AC-DC switch is made up of controllable silicon and rectifier bridge, and when lever or other metal parts during away from proximity transducer, the inductance type oscillating circuit satisfies oscillating condition, produces the oscillator signal of about 150KHZ.This signal is added to the transistorized base stage of thyristor gating circuit by electric capacity by its transistorized emitter stage.The positive half cycle of signal is guaranteed adequate food the crystal of thyristor gating circuit and is closed conducting, and negative half period ends it.When ending, electric current charges to the electric capacity of thyristor gating circuit through rectifier bridge and resistance.During conducting, electric capacity then discharges through the transistor of thyristor gating circuit.Because discharge time constant is far smaller than charge constant, so in the transistor duration of oscillation of inductance type oscillating circuit, the electric capacity two ends pressure drop of thyristor gating circuit approaches zero, the triggerless pulse adds to the SCR control utmost point, controllable silicon is in off state, 12～15V DC voltage is arranged between the circuit both positive and negative polarity, be duty.
When lever or other metal parts during near proximity transducer, the magnetic field of induction coil will produce eddy current in metal parts, cause bigger energy loss, and the amplitude conditions of vibration is not being met, and vibration stops.At this moment, the transistor of thyristor gating circuit will be in cut-off state always, and the two ends pressure drop of the electric capacity of thyristor gating circuit is risen gradually, and controllable silicon is triggered.After the conducting between power positive cathode by short circuit, the 380V ac contactor coil is because of decompression, iron core discharges, whole circuit is off state, the drive motors stall.
Stop and the starting button that are installed with on the switch cover can manually be controlled electronic circuit.The diode displaying hole that has on it then can show work or off state.Light emitting diode is connected on the transistorized colelctor electrode of thyristor gating circuit.
The task of the utility model loom battery-conserving switch comes to this and finishes.
The utility model provides a kind of can make loom and the stall of drive motors automatic stopping thereof when cracked ends, crapand, fabric defect take place; thereby saves energy greatly; and noiseless, contactless, no temperature rise again; delay function is arranged; drive motors there are decompression, under-voltage protection performance; voltage change there are big accommodation, control reliable sensitive loom battery-conserving switch.It is in the past energy-conservation 10～20%, has improved the power factor of supply line.Whole electronic circuit is contactless, no heater element, thereby do not have temperature rise, noiseless.Electronic circuit self has decompression, short circuit, overload, under-voltage protection function, can not cause motor to damage.The utility model adopts connector to connect, and keeps in repair, installs all very convenient.The utility model can be widely used in the loom of multiple models such as 1511,1515.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
