Abstract
The utility model provides a weft breaking automatic detection system for a steel skeleton plastic composite pipe production line. The weft breaking automatic detection system comprises a current transformer mounted at the primary grade of a welding transformer, four diodes, a potentiometer, an analog-digital module and a PLC (Programmable Logic Controller), wherein the current transformer is used for adjusting the sensitivity through changing a primary turn number and detecting current size of the welding transformer; the four diodes are used for carrying out full-wave rectification on induction current of the current transformer and converting alternating current into direct current; the potentiometer is used for adjusting to suitable voltage; the analog-digital module is used for converting an analog quantity into a digital quantity; and the PLC is used for confirming whether the line is broken or not according to a signal of the analog-digital module; and if the line is broken, a control signal is sent and the production line automatically stops and sends out a corresponding alarming signal. According to the weft breaking automatic detection system disclosed by the utility model, the PLC judges that a secondary output of the welding transformer is an open circuit or welding current so as to determine whether the line is broken or not and realize that the steel skeleton plastic composite pipe production line cannot carry out weft breaking automatic detection and stopping; and therefore, the automation level of equipment is improved, the labor intensity of workers is reduced and the equipment protection is enhanced.
Description
Technical field
The utility model relates to a kind of for steel skeleton plastic clad pipe production line parallel broken string automatic checkout system, belongs to technical field of electricity.
Background technology
Existing steel skeleton plastic clad pipe production line owing to there is not broken thread detector, can only rely on artificial discovery fully.When broken string occured, equipment also can continue to produce, and as in time not shutting down, the parallel broken end enters the moulding position, may scratch inside and outside shaping mechanism, and produces waste product, causes damage.
Summary of the invention
It is a kind of for steel skeleton plastic clad pipe production line parallel broken string automatic checkout system that the utility model provides, be used for solving the broken thread detector that do not have of existing steel skeleton plastic clad pipe production line existence, can only rely on the problem of manual detection, the utility model proposes following technical scheme for this reason:
A kind of for steel skeleton plastic clad pipe production line parallel broken string automatic checkout system, comprise: current transformer, four diodes, potentiometer, modulus module and PLC, the signal output part of current transformer is connected with the signal input part of four diodes, the signal output part of four diodes is connected with the signal input part of potentiometer, the signal output part of potentiometer is connected with the signal input part of modulus module, and the signal output part of modulus module is connected with the signal input part of PLC;
Be installed in the elementary current transformer of welder transformer, be used for regulating sensitivity by changing primary turns, and detect the size of current of welding transformer;
Four diodes are used for the induction current of mutual inductor is carried out full-wave rectification, and alternating current is converted to direct current;
Potentiometer is adjusted into suitable voltage with the direct current of four diode conversions;
Modulus module is used for analog quantity is converted to digital quantity;
PLC is used for being confirmed whether broken string according to the signal of modulus module, makes the production line auto stop if broken string then transmits control signal, and send corresponding alerting signal.
The utility model can be opened a way or welding current by the secondary output of PLC judgement welding transformer; thereby determine whether broken string; realized that the steel skeleton plastic clad pipe production line can not carry out the parallel broken string and automatically detect and shut down; thereby improve the equipment automatization level; reduce operating personnel's labour intensity, strengthened equipment protection.
Description of drawings

The electrical block diagram that is used for steel skeleton plastic clad pipe production line parallel broken string automatic checkout system that Fig. 2 provides for embodiment of the present utility model.
Embodiment
The below is described in further detail the utility model: present embodiment is implemented under take technical solutions of the utility model as prerequisite, has provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
It is a kind of for steel skeleton plastic clad pipe production line parallel broken string automatic checkout system that this embodiment provides, as depicted in figs. 1 and 2, comprise: current transformer 1, four diodes 2, potentiometer 3, modulus module 4 and PLC5, the signal output part of current transformer 1 is connected with the signal input part of four diodes 2, the signal output part of four diodes 2 is connected with the signal input part of potentiometer 3, the signal output part of potentiometer 3 is connected with the signal input part of modulus module 4, and the signal output part of modulus module 4 is connected with the signal input part of PLC5;
Be installed in the elementary current transformer of welder transformer 1, be used for regulating sensitivity by changing primary turns, and detect the size of current of welding transformer;
Four diodes 2 are used for the induction current of mutual inductor 1 is carried out full-wave rectification, and alternating current is converted to direct current;
PLC5 is used for being confirmed whether broken string according to the signal of modulus module 4, makes the production line auto stop if broken string then transmits control signal, and send corresponding alerting signal.
Equipment downtime or when starting will, the burn out detection switch is beaten to enable position during normal operation behind the device start, the broken string automatic checkout system brings into operation.In process of production, for a certain reason, make one or two parallels disconnections, the secondary output of welding transformer can be opened a way or larger variation (accidental other positions that snaps into of broken string the end of a thread) occurs welding current, the curent change that mutual inductor detects, and be delivered among the PLC by potentiometer, modulus module, PLC determines whether broken string by computing.As confirm broken string, then M10.0 is set, and sends stopping signal, equipment auto stop, simultaneously alarm lamp flicker.The staff closes detection system, and handling failure after the startup normally, is opened automatic checkout system again, normal production.
The variation from 29 amperes to 95 amperes of the secondary output current of welding machine is with 150 to 5 mutual inductors, after the full-wave rectification, by the potentiometer adjustment, make output voltage be no more than 12 volts, become the voltage adaptive with analog to digital converter, 0 volt to 12 volts voltage becomes 0 to 32767 numeral in the PLC internal conversion.When numeral is lower than 4000, just assert it is broken string.When digital above 4000, equipment is defined as normally.
The technical scheme that adopts this embodiment to provide; secondary output by PLC judgement welding transformer can be opened a way or welding current; thereby determine whether broken string; realized that the steel skeleton plastic clad pipe production line can not carry out the parallel broken string and automatically detect and shut down; thereby improve the equipment automatization level; reduce operating personnel's labour intensity, strengthened equipment protection.
The above; it only is the better embodiment of the utility model; these embodiments all are based on the different implementations under the utility model general idea; and protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
