Description
Technical field
The present invention is specifically related to a kind of yarn on-Line Monitor Device and energy-saving control method of low-power consumption, belongs to spinninging technical field.
Background technology
To check and process spun yarn broken yarn is one of task of textile mills spun yarn spinner, and wherein tours of inspection broken yarn occupies the overwhelming majority time, this part time does not process the broken yarn of spun yarn, is therefore actually the non-productive work time.
For addressing this problem, ring spun yarn broken yarn online measuring technique arises at the historic moment.Can spun yarn broken yarn on-line monitoring technique guide spinner to find spun yarn broken yarn fast, its application can be monitored the situation of spinning end breaking in time and be understood the distribution of broken yarn on each ingot position of fine spining machine, analysis broken end reason in real time, administrative staff can be allowed to apply these feedback informations targetedly, ingot speed restraining factors can be improved simultaneously, optimize spinning process condition, Optimized Operation keeps off a car and maintenance plan etc., improving Spinning process efficiency, promote production capacity, reduce and consume, save recruitment, oil recovery enhancement and improve management.
The dynamo-electric Co., Ltd of Shanghai Pacific Ocean propose a kind of photoelectric sensing monitor head is set below twizzle broken yarn detection scheme and apply for a patent that (application number is: 200520045862.2), the spun yarn thread-carrier of the Yarn break checkout gear of this system is made up of a thread board and a pressure strip, pressure strip is arranged on thread board, pressure strip and thread board are connected by screw fixing, a twizzle is fixedly installed between thread board and pressure strip, one end of thread board is provided with a concave indentation, twizzle is arranged on the top of concave indentation, photo electric sensitive element is provided with in the both sides of concave indentation, the other end of thread board has a guide grillage by pinned connection.During normal spinning, spun yarn by twizzle around on the bobbin of fine spining machine.When spinning end breaking, pass through without spun yarn in twizzle, the photo electric sensitive element of thread board concave indentation both sides sends broken yarn signal immediately, and broken yarn signal is delivered to controller by wire.Whether this system only can detect spun yarn and break end, and cannot detect the duty of spun yarn air ring.
RingRoute is the spun yarn broken yarn detection system proposed by Southern Yangtze University, this system is based on the Shanghai two frame EJM128 type fine spining machine of domestic main flow, have developed single spindle type spun yarn broken yarn detection system, the method is for detecting the variation characteristic of the signal of steel traveler.According to the change of steel traveler motion feature thus diagnosis spinning fault, it comprises Yarn break, spindle skidding, steel traveler wearing and tearing etc.(bibliography: Liu Jihong, Xu Yang, Song Xiaoliang, the state of development of ring spun yarn broken yarn on-line checkingi, cotton textiles industry, the 1st phase in 2013,59-65 page).
The detection method of the ring spinning frame duty that Southern Yangtze University proposes and determination methods (application number: 201210232141.1), the method can arrange induction installation by sensing region at fine spining machine air ring, the data signal that the revolution of described induction installation induction spun yarn air ring produces, analyzes the data signal exported thus judges the duty of ring spinning frame.Propose ballooning of yarn when adopting photoelectric sensor monitoring spinning in the method, and be data signal by air ring condition conversion, with the statistical nature of data signal, the duty that fine spining machine occurs is monitored.
Because the number of spindle unit of a fine spining machine is generally more than 400, usual short car is 420 ingot positions and 480 ingot positions, and long vehicle is 1080 ingot positions, in such scheme, because each ingot position is detected in real time, therefore all ingot positions all keep constant duty, therefore cause energy consumption high, electric current is large, and the stability of system reduces.
Summary of the invention
The energy consumption that the object of the invention is to detect for the ring spinning frame broken end of textile industry is high, electric current large, this problem of poor stability of system, propose in existing broken end detection system, utilize the working method that poll starts, eliminate unnecessary energy loss, thus reach the object reducing energy consumption, reduce system power, improve the stability of system.
Present system is formed as shown in Figure 1, system comprises a headstock main control singlechip 1, multiple sub-single-chip microcomputer 2 and multiple probe 3, host scm 15 to be connected with communicate by 485 between sub-single-chip microcomputer 2 and sub-single-chip microcomputer 2, and control mode employing pulse 4 controls, for yarn on-line monitoring.Below the lappet being arranged on fine spining machine to pop one's head in or on ring rail, spun yarn exports from front roller 1 as shown in Figure 2, spinning section 2 is by twizzle 3 and be wound up into above bobbin 5 after being arranged on rings 6 twizzle 4, probe can detect air ring that spun yarn formed or rotate components and parts 4, detects whether there is spinning end breaking phenomenon.During thousand ingot due to spun yarn, end breakage rate is below 50, for the message transmission rate of sub-single-chip microcomputer for 9600bps, according to one broken end data be that 1bit represents, then can transmit the spinning end breaking data of about 192 hours each second, namely can complete for 1 second 8 days data transmission.But ring spinning frame broken end detection system is in practical work process, the real-time detected the broken end of yarn is not high, and its time error was acceptable within 20 seconds; For fine spining machine broken end every 2 minutes of the quantity of 480 ingot positions within 1, therefore not obvious according to the meaning measured at a high speed shown in Fig. 3.
For realizing the object reducing energy consumption, reduce system power, improve the stability of system, the present invention adopts following technical scheme: be that a polling cycle carries out data acquisition to each probe according to the setting-up time being less than 20 seconds shown in Fig. 4, actual transmissions probe number is caused to reduce, probe on a fine spining machine is divided into some groups, first first group of data is gathered after poll starts, after collection completes, first group of probe and corresponding sub-single-chip microcomputer enter sleep state; And then gather second group of data, after having gathered, second group of probe and corresponding sub-single-chip microcomputer enter sleep state; The like, until gather last group data, after having gathered, all probes and corresponding sub-single-chip microcomputer enter sleep state; By the time after setting-up time arrives, then new round inquiry is restarted.
To some groups of probes, data acquisition is carried out successively according to such as Fig. 5 for wherein each group, after poll completes, single-chip microcomputer is in resting state, the LED of probe and receiving tube extinguish, due to 80% LED and the receiving tube coming from probe of the energy consumption of system, therefore in polling procedure, the energy consumption of system about reduces, after end of polling(EOP), the energy consumption of system is lower, thus reaches the object of expection.
This device had both been suitable for the fine spining machine of other industries such as being also applicable to wool spinning with the fine spining machine of textile industry, bast fibre spinning, look spin.
This device can be generalized to the similar rove section with the Speed frames of spinning section, same is suitable for industries such as spinning with cotton spinning, wool spinning, bast fibre spinning, look.
Monitoring method of the present invention and determination methods have following advantage:
1, this system only revises the software of existing fine spining machine broken end detection system, and does not need the hardware resource of increase system.
2, this system can ensure the precision of the data acquisition of system and the requirement of frequency, eliminates unnecessary energy loss simultaneously, thus reaches the object reducing energy consumption, reduce system power, improve the stability of system.
