Description
Technical field
This utility model is specifically related to yarn on-Line Monitor Device and the energy-saving control method of a kind of low-power consumption, belongs to spinninging technical field.
Background technology
Inspection and process spun yarn broken yarn are one of tasks of textile mills spun yarn spinner, and wherein tours of inspection broken yarn occupies the overwhelming majority time, and this part-time does not process the broken yarn of spun yarn, is therefore actually the non-productive work time.
For solving this problem, ring spun yarn broken yarn online measuring technique arises at the historic moment.Can spun yarn broken yarn on-line monitoring technique quickly guide spinner to find spun yarn broken yarn, its application can be monitored the situation of spinning end breaking in time and understand broken yarn distribution on each ingot position of spinning frame in real time, analyzes broken end reason, management personnel can be allowed to apply these feedback informations targetedly, can improve simultaneously ingot speed restraining factors, optimize spinning process condition, Optimized Operation is kept off a car and maintenance plan etc., to improve Spinning process efficiency, to promote production capacity, reduce and consume, save recruitment, improving quality and improve management.
Shanghai Pacific Ocean electromechanics company limited proposes a kind of broken yarn detection scheme arranging photoelectric sensing monitor head below twizzle and applies for a patent (Application No.: 200520045862.2), the spun yarn yarn guide 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 it 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, it is provided with photo electric sensitive element in the both sides of concave indentation, the other end of thread board is connected by bearing pin a guide grillage.When normally spinning, spun yarn passes through twizzle on the bobbin of spinning frame.When spinning end breaking, passing 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.This system only can detect whether spun yarn breaks end, it is impossible to the duty of detection spun yarn air ring.
RingRoute is the spun yarn broken yarn detection system proposed by Southern Yangtze University, and this system, based on the Shanghai two frame EJM128 type spinning frame of domestic main flow, have developed single spindle type spun yarn broken yarn detection system, and the method is for detecting the variation characteristic of the signal of wire loop.Change according to wire loop motion feature thus diagnose spinning fault, it includes the skidding of Yarn break, spindle, wire loop abrasion etc..(list of references: Liu Jihong, Xu Yang, Song Xiaoliang, the state of development of ring spun yarn broken yarn on-line checking, 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 spinning frame air ring, the digital signal that the sensing spun yarn air ring revolution of described induction installation produces, is analyzed the digital signal of output thus judges the duty of ring spinning frame.Ballooning of yarn when proposing employing photoelectric sensor monitoring spinning in the method, and be digital signal by air ring condition conversion, it is monitored with the duty that spinning frame is occurred by the statistical nature of digital signal.
Owing to the number of spindle unit of a spinning frame is typically more than 400, usual short car is 420 ingot positions and 480 ingot positions, and long vehicle is 1080 ingot positions, in such scheme, owing to each ingot position is detected in real time, the most all of ingot position all keeps constant duty, thus results in energy consumption high, electric current is big, and the stability of system reduces.
Utility model content
The purpose of this utility model is that the energy consumption of the ring spinning frame broken end detection for textile industry is high, electric current is big, this problem of poor stability of system, propose in existing broken end detecting system, utilize the working method that poll starts, eliminate unnecessary energy loss, thus reduce the purpose of the stability of energy consumption, reduction system power, raising system.
This utility model system is constituted as shown in Figure 1, system includes a headstock main control singlechip 1, many sub-single-chip microcomputers 2 and multiple probe 3, being connected by 485 communications 5 between host scm 1 with sub-single-chip microcomputer 2 and sub-single-chip microcomputer 2, control mode uses pulse 4 to be controlled, for yarn on-line monitoring.It is arranged on below the lappet of spinning frame or on ring rail with probe, spun yarn exports from front roller 1 as shown in Figure 2, spinning section 2 is wound up into above bobbin 5 by twizzle 3 after the twizzle 4 being arranged on rings 6, probe can detect air ring or the rotation components and parts 4 that spun yarn is formed, and has detected whether spinning end breaking phenomenon.Due to during thousand ingot of spun yarn end breakage rate below 50, as a example by the message transmission rate of sub-single-chip microcomputer is as 9600bps, it is that 1bit represents according to broken end data, then can transmit the spinning end breaking data of about 192 hours each second, the data transmission of 8 days i.e. within 1 second, can be completed.But ring spinning frame broken end detecting system is in practical work process, the real-time of detection of breaking end yarn is the highest, and its time error was acceptable within 20 seconds；For the spinning frame of 480 ingot positions every 2 minutes of the quantity that breaks end within 1, therefore according to the meaning measured at a high speed shown in Fig. 3 inconspicuous.
For realizing reducing the purpose of the stability of energy consumption, reduction system power, raising system, this utility model adopts the following technical scheme that and as a polling cycle, each probe is carried out data acquisition according to the time that sets less than 20 seconds shown in Fig. 4, actual transmissions probe number is caused to reduce, probe on one spinning frame is divided into some groups, first poll gathers first group of data after starting, after collection completes, first group of probe and corresponding sub-single-chip microcomputer enter sleep state；Gathering second group of data the most again, after having gathered, second group of probe and corresponding sub-single-chip microcomputer enter sleep state；The like, until gathering last group data, after having gathered, all probes and corresponding sub-single-chip microcomputer enter sleep state；By the time after the time that sets arrives, then new round inquiry is restarted.
For each of which group according to successively some groups of probes being carried out data acquisition such as Fig. 5, poll complete after single-chip microcomputer in a dormant state, LED and the reception pipe of probe extinguish, owing to 80% LED coming from probe of the energy consumption of system is managed with receiving, 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 intended purpose.
This device had both been suitable for the spinning frame of other industries such as being also applied for wool spinning with the spinning frame of textile industry, bast fibre spinning, color spin.
This device can be generalized to the rove section of the fly frame with spinning section being similar to, equally applicable with the industry such as cotton spinning, wool spinning, bast fibre spinning, color spin.
Monitoring method of the present utility model and determination methods have an advantage that
1, this system only revises the software of existing spinning frame broken end detecting system, without the hardware resource increasing system.
2, this system can ensure that the precision of data acquisition and the requirement of frequency of system, eliminates unnecessary energy loss simultaneously, thus reduce energy consumption, reduce system power, improve the purpose of the stability of system.
