Description
Technical field
The present invention relates to a kind of control method of jet loom is and in particular to a kind of main motor starting for jet loom
The method being controlled.
Background technology
The main motor of water and air injection loom passes to main shaft and relative motion part through main transmission, realizes loom
Various actions.The main transmission of loom has indirect type and direct-type two big class.In the direct-type kind of drive, drive motor with knit
Machine directly links, and the driving-chain between motor and main shaft does not exist clutch, and structure is simple, and when loom is shut down, motor is not sent out
Raw idle running, is therefore widely adopted.For example, Chinese invention patent cn101914831a discloses a kind of loom drive mechanism,
Including by the main shaft of drive motor, the beating-up mechanism power transmission shaft being connected with spindle drive respectively and shedding mechanism input shaft,
Control the drive mechanism of main shaft axial movement and the stop device making the stopping of beating-up mechanism power transmission shaft, wherein, drive horse side
Output shaft is provided with former moving gear, and main shaft is provided with first gear, and former moving gear is engaged with first gear, is achieved in direct-type
Transmission.
Loom after a stoppage, due to the stretching of warp surface tension generation, can make to produce neutral gear, filling density when loom is started shooting through face
More loose, more easily produce neutral gear, and itself and caused by loom stop time correlation.This neutral gear is otherwise known as bad start-up, thereby results in
The decline of fabric quality.For solving the above problems, Chinese invention patent application cn104975418a discloses a kind of loom and drives
Trace minimizing technology, start when only start main shaft, reed fan the air latitude some under, after spindle speed reaches predetermined speed, loom
Start normal work.This method is subject to larger restriction in actual use, and for example, this is disclosed herein, in many cases, main shaft
During startup, heald frame also can and then start, and spindle settings are reversed the asynchronous shadow bringing to eliminate heald frame card for some circles by it
Ring.The method can lead to startup control system complicated, meanwhile, as when parking between length different when, parallel pine is got over degree and can change,
Different to the influence degree of bad start-up, the method can not solve the problems, such as that different down times cause.
Based on the problems referred to above it is considered to staring torque after changing loom and shutting down, it is suitable that first time beating is provided
Beating-up force, to avoid fabric bad start-up.Using asynchronous machine, servomotor etc. as main shaft direct drive motor, a side
Face starting current is excessive, on the other hand it is difficult to be controlled to toggle speed, usually, is connected using triangle and realizes starting
The method changing into Y-connection afterwards is controlled to motor, and the main motor of loom electric cabinet of the prior art only has five startups
Shelves, toggle speed changes greatly, when selecting slower toggle speed, will make to beat up and cannot be ejected into position for the first time, and lead to stop
Machine, quality problems in cloth cover, and open-set mark phenomenon also occurs, and select faster toggle speed when although the first latitude can arrive
Reach position, but also easily cause the quality problems of the tight shelves of filling face.
Therefore, it is necessary to improve to the main motor starting control method of loom, of the prior art above-mentioned to solve
Problem.
Content of the invention
The goal of the invention of the present invention is to provide a kind of main motor starting control method for jet loom, to solve loom
Open-set mark during start, tight shelves problem.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of main motor for jet loom opens
Flowing control method, using magneto resistance speed-regulating motor as the main motor of jet loom, stores magneto resistance speed-regulating motor in the controls
Toggle speed and magneto resistance speed-regulating motor control electric current corresponding relation data table；Detection jet loom down time, according to stopping
The car time, determine corresponding toggle speed, the caused by loom stop time is longer, and toggle speed is faster, and the time reaching rated speed gets over
Short；According to toggle speed, determine the control electric current of magneto resistance speed-regulating motor, control magneto resistance speed-regulating electric motor starting, be achieved in spraying
The control of the main motor of loom.
Preferably technical scheme, the selection of described toggle speed makes main motor reach rated speed in 1～10 second.
In technique scheme, toggle speed is determined in following scope according to down time:
Down time≤3 minute, per second accelerate 0.5～1 turn；
3 minutes ＜ down time≤10 minute, per second accelerate 1～2 turn；
10 minutes ＜ down time≤30 minute, per second accelerate 2～3 turns；
30 minutes ＜ down time≤60 minute, per second accelerate 3～4 turns；
Down time ＞ 60 minutes, per second accelerate 4～10 turns.
Because technique scheme is used, the present invention compared with prior art has the advantage that
1st, the present invention adopts magneto resistance speed-regulating motor as the main motor of jet loom, it is possible to achieve to jet loom toggle speed
Precise control, accelerator can be divided into the friction speed of more than 100, thus can change spray by controlling toggle speed
Penetrate beating dynamics when loom starts, thus solving the problems, such as driving open-set mark or tight shelves；
2nd, main for the loom toggle speed of motor is associated by the present invention with the down time of loom, and the caused by loom stop time is longer, starts
Speed is faster, and the caused by loom stop time is shorter, and toggle speed is slower, thus solves and leads to filling density tension force due to down time difference
Change the driving trace problem causing.
Specific embodiment
With reference to embodiment, the invention will be further described:
Embodiment one: a kind of main motor starting control method for jet loom, knitted as injection using magneto resistance speed-regulating motor
The main motor of machine, the toggle speed of storage magneto resistance speed-regulating motor is corresponding with magneto resistance speed-regulating motor control electric current in the controls
Relation database table；Detection jet loom down time, according to down time, determine corresponding toggle speed, make main motor 1～
Rated speed is reached, the caused by loom stop time is longer, and the time reaching rated speed is shorter in 10 seconds；According to toggle speed, determine
The control electric current of magneto resistance speed-regulating motor, controls magneto resistance speed-regulating electric motor starting, is achieved in the control of the main motor of jet loom.
The control of toggle speed can be determined by experiment according to the actual demand that main rated motor rotating speed, fabric produce.
So that main rated motor rotating speed is 600 revs/min as a example, startup speed can be determined in following scope according to down time
Degree:
Down time≤3 minute, per second accelerate 0.5～1 turn；
3 minutes ＜ down time≤10 minute, per second accelerate 1～2 turn；
10 minutes ＜ down time≤30 minute, per second accelerate 2～3 turns；
30 minutes ＜ down time≤60 minute, per second accelerate 3～4 turns；
Down time ＞ 60 minutes, per second accelerate 4～10 turns.
Test shows, the control method using the present embodiment controls main motor starting, can effectively eliminate bad start-up.
