Description
Technical field
The present invention relates to a kind of control method of reciprocal upgrading mechanism, specifically, is the control method of the reciprocal upgrading mechanism of a kind of textile machine----in the cop winding machine.
Background technology
Back and forth upgrading mechanism is a kind of common apparatus in textile machine.The function of this mechanism is to make working part produce reciprocal level to rise action: promptly working part rises a straight line rising of some beginning (or decline) motion from level, the distance of motion is called a traverse and rises (or decline) highly, do decline (or rising) motion along this straight line again, the distance of motion is called a traverse and descends (or rising) highly, traverse rising (or decline) highly is slightly larger than traverse and descends (or rising) highly, working part rises (or decline) traverse rising (or decline) highly along this straight line more then, descend (or rising) traverse decline (or rising) highly along this straight line again, and so forth.
In the prior art, the crank motion of textile machine is realized by the mechanical gear transmission: three phase asynchronous motor is by worm screw, worm gear drives cam rotation, lifting lever is made circular movement according to rotor along cam wheel rim curve, thereby lifting lever is up and down reciprocatingly moved, and the difference of cam vertex and nadir is traverse; When pumping, lifting lever drives driving lever, driving lever is fixed on level again and rises on the lever, level rises lever and makes strut support movable pendulum arm with the synchronous up-and-down movement of lifting lever, and the ratchet that is contained in the swing arm is limited in the special arc groove, supports the external tooth of ratchet forward along groove; Ratchet is realized step motion by axle drive sprocket wheel.Realized that so just working part crank motion level rises action.
Thisly all rely on mechanically operated textile machine to have following shortcoming: the one, applicable area is little, and institute's product processed is more single, and a lot of products can't be processed at all.Even so, even can process, all need artificial the adjustment in the conversion kind, very cumbersome, efficient is low at every turn.This is because 1. when traverse arrives highs and lows by the cam curve decision, also need dispose gear cluster if change; During change, need manually to adjust, the traverse size also can't change; 2. a level rise is limited by ratchet diameter and ratchet deep-slotted chip breaker, can only change within the specific limits, and level raising frequency rate can't change.The 2nd, low precision.The mechanical type transmission must be made up of a lot of parts, and the accumulated error of each parts assembling of process and assemble sum of errors of each parts causes the machine run precision low.The machine period of service is long more, and precision is poor more.The 3rd, the fault rate height.When relying on mechanical drive realization crank motion level to rise action entirely, the factors such as operation lack of standardization when changing the part adjustment owing to the normal wear of part in the use fully with artificial replacing all may cause fault.
Summary of the invention
The technical matters that the present invention solves is that existing reciprocal upgrading mechanism control method applicable area is less, low precision, problem that benefit is low, provides a kind of traverse size, level rise, level to rise the control method of the reciprocal upgrading mechanism that number of times etc. can regulate arbitrarily.
The control method of reciprocal upgrading mechanism of the present invention, this reciprocal upgrading mechanism comprise a grade lifting motor, working part, connection level lifting motor output shaft and working part driving device, by transmission line is connected with the level lifting motor treater with the action of controlled stage lifting motor, with the memory device of treater bonded assembly storage data and program, and treater bonded assembly input equipment, this control method may further comprise the steps:
Treater reads relevant data and the program in the memory device;
Rise data such as number of times according to traverse angle of elevation, traverse decline angle, level, treater controlled stage lifting motor rotates a traverse angle of elevation, the traverse decline angle of reversing again, and then rotate a traverse angle of elevation, the traverse decline angle of reversing again; So repeatedly, equal level up to repeatedly number of times and rise number of times.
As to a kind of improvement of the present invention, can before above-mentioned steps, increase following steps:
Treater reads relevant data and the program in the memory device;
According to early stage number of revolutions, early stage data such as rotational angle, the action of treater controlled stage lifting motor: if early stage number of revolutions for once, angle of level lifting motor rotation then; If early stage, number of revolutions was a secondary, after then the level lifting motor rotates an angle, the same angle of reversing again; If early stage, number of revolutions was three times, after then the level lifting motor rotates an angle, the same angle of reversing again, and then rotate a same angle, number pushes away according to this:
The level that turns to treater controlled stage lifting motor rises the some position.
As to further improvement of the present invention, can after above-mentioned steps, increase following steps:
Treater controlled stage lifting motor turns to final position.
Above-described control method can also comprise in the described step by input equipment changing the value of relevant data and depositing the step of memory device in.
Coordinate mutually for the action that makes other major part in reciprocal upgrading mechanism and the equipment, can on above-mentioned treater, connect main motor, following steps also in this control method by transmission line:
Before the level lifting motor was going to initial position, treater was controlled main motor outage stall;
After the level lifting motor went to initial position, treater was controlled main motor and is got electric rotation;
When the level lifting motor turned to final position, treater was controlled main motor and is realized a crawl.
Adopt control method of the present invention, need input stage lifting motor traverse angle of elevation (or corresponding traverse rise height of making the moving working part of reciprocal level elevator), level lifting motor traverse decline angle (or corresponding traverse falling head of making the moving working part of reciprocal level elevator), level to rise the value of basic specifications such as number of times, level lifting motor revolution; As required, back and forth the initial position of level elevator before moving, early stage rotational angle, early stage, number of revolutions, level rose parameters such as some position and final position to need input.Certainly, the numerical value of this this parameter also can reset and import as required.
Beneficial effect of the present invention: 1, control method of the present invention has broken through traditional mechanical type equipment fully by the mode of mechanical adjustment, need not to be equipped with machine partss such as various gears, ratchet, belt pulley, has reduced the operation cost of equipment; 2, but level lifting motor traverse angle of elevation, level lifting motor traverse decline angle, level rise number of times, the isoparametric value step-less adjustment of level lifting motor revolution, and it is wider to adapt to product processed, and very simple in the conversion kind, the efficient height; 3, the microprocessor that adopts the advanced person is as the control core, and operation accurately, steadily, reliably.
Description of drawings
Fig. 1 is guide plate each location diagram in once moving in one embodiment of the present of invention.
Fig. 2 is the operation block diagram of the program of the treater among the described embodiment.
The specific embodiment
Be that the invention will be further described for example below with the cop winding machine.
Cop winding machine is with the equipment of yarn on the shuttle.Input equipment, memory device in the cop winding machine in the reciprocal upgrading mechanism are connected on the treater, and treater is connected with level lifting motor, main motor respectively by transmission line; Level lifting motor output shaft connects an end of chain, and the other end of chain is connected to be done on moving working part----the guide plate of reciprocal level elevator.The level lifting motor is selected stepping motor for use.Main motor output shaft drives shuttle and rotates by main shaft disk, the band that splits.The yarn that passes the guide plate is about to yarn and is wrapped on the shuttle on shuttle when shuttle rotates.For yarn is wrapped on the shuttle by certain requirement, the guide plate need move up and down being parallel on the axial direction of shuttle.Thereby this motion is to come back rotation by chain drive guide plate up-and-down movement to realize according to the programming control stepping motor output shaft that is stored in the memory device around its axis by treater.
Guide plate each position in once moving concerns that as shown in Figure 1 Fig. 2 is the operation block diagram of program.
When program brings into operation,, or rotate counterclockwise by input keyboard manual control step motor cw and the guide plate is moved up and down get back to final position X (around tail yarn position) if the guide plate is in final position X (around tail yarn position).Then treater reads the value and the program of each parameter, makes stepping motor rotate counterclockwise an angle A then and moves on to initial position Z (around insurance yarn initial position) on the guide plate to making.
When guide plate one to initial position Z (around insurance yarn initial position), treater is promptly controlled main motor and is got electric rotation, begins around the insurance yarn.Stepping motor continues the inverse time and rotates a rotational angle B in early stage (corresponding to once around the length of insuring yarn) arrival end position U (once around insurance knot bundle position), then, stepping motor clockwise rotates angle B more respectively, rotate counterclockwise angle B returns end position U, so just around having got (around the number of times of insurance) insurance yarn three times.
Stepping motor clockwise rotates angle C and arrives a level rise point position Y then, and beginning back and forth level rises action.Simultaneously, treater is controlled main motor and is continued rotation, begins to rise point around yarn from level.Stepping motor rotates counterclockwise traverse angle of elevation D (corresponding to the traverse rise height) earlier, clockwise rotate traverse decline angle E (corresponding to the traverse falling head) again, another mistake hour hands rotational angle D clockwise rotates the E angle again, and three times repeatedly (level rises number of times) arrives full packages position W.
Last stepping motor clockwise rotates a lower angle F, arrives final position X (around tail yarn position).One arrives final position X, and treater is promptly controlled main motor and realize the stall of cutting off the power supply of a crawl after being got the tail yarn.Crawl time length has determined the length of tail yarn.So just finish motion process one time.
In this process, angle A, B, C, D, E, F and level rise number of times, number of revolutions, stepping motor rotating speed all can be set and be stored in the memory device by input media in earlier stage.Wherein the effect of angle A is to control the moment that main motor gets electric operation (or around insurance yarn initial position), so this parameter of angle A can not appear in the program yet, and reaches this function by another method.Promptly send a control signal to treater as detecting by sensor after the stepping motor output shaft moves to certain position, treater is controlled main motor immediately and is got electric rotation.
Because angle A, B, C, D, E, F and level rise number of times, the early stage number of revolutions, these parameters of stepping motor rotating speed can steplessly change, adjustment by these parameter values, can realize insuring yarn length (=once around the insurance yarn length * around the insurance yarn number of times), level rises point, level rise (=traverse rise height-traverse falling head), the traverse frequency (is finished the number of times of traverse in the unit time, can realize by changing the stepping motor rotating speed), full packages height (=traverse rise height+level rise * level rises number of times), isoparametric whole quantifications of tail yarn length and stepless variation, applicable area is extremely wide.
The present invention also can be applicable to fly frame, spinning frame, twisting machine, derby doubler, drawing frame, bobbin-winding machine etc. to have on the equipment of reciprocal upgrading mechanism, and this kind equipment is controlled.This also belongs to protection scope of the present invention.
