In winding process, yarn, by the sense silk head of yarn probe, can obtain different light-operated effects.By a sense silk device can detect have or not broken yarn, yarn be reel in or stop.Master cpu sends to fixed length control device by RS-485 bus by the fixed-length data of setting and winding speed information.Fixed length control device adopts high-speed microprocessor to control, and detects in real time reel for yarn around situation, through calculating reel for yarn around length.When coiling length reaches preseting length, drive trimming electromagnet to cut off yarn, and light indicator lamp and alarm lamp.By reset button, can again reel.If in winding process, there is Yarn break, fixed length plate will be lighted indicator lamp and alarm lamp.A fixed length plate can be controlled 4 spindles.And the yarn probe left side is power valve, the right is adoptor, adopts infrared ray, can certainly be contrary.By infrared emitting and acceptance, yarn is through between emitting head and accepting header, and the burr by yarn, blocks difference to light, by electric circuit inspection, can obtain having or not yarn, yarn to have or not and walk about.
In addition, existence due to wind2 medium dip, the laying head 232 traversing in reciprocator that driven by groove drum 24 carries out traverse motion with regard to automatically catching on yarn, and as the unique design of above-mentioned tension-adjusting gear 8 and groove drum body 21, yarn will enter in the yarn positioning groove of spacing porcelain head 812 automatically, carries out high-speed coiling.Now can be according to the needs of Tensity size in practical operation, by regulating ring 83, regulate, such as, before coiling, first the first regulating ring projection is socketed on adjustable column upward, when the yarn that carrys out self-aiming porcelain head 811 is shown plane on through the first regulating ring and is entered spacing porcelain head 812 and start to reel, as required, can by the second regulating ring even the 3rd regulating ring together projection be socketed on adjustable column down, to push down yarn, yarn is advanced near adjustable column 82 at the plane domain of regulating ring 83.Finally, creeling: after coiling, lift winding stand 30, drive motor is closed, reciprocator 23 stop motion gradually of traversing in friction roll shaft 31 and groove drum, now, operative employee holds full yarn cylinder, pushes left grillage 111 open, takes off full yarn cylinder, and change sky yarn cylinder, retracing spring 113 makes winding stand 10 return to clamp position.
In winder, on bobbin, the coiling route of yarn is reciprocal helix line, and bobbin is reeled and is formed by stacking with two motions of crank motion by rotatablely moving.Wherein the rotation of friction roller driven by motor bobbin is reeled, and groove drum drives the laying head in groove drum to move reciprocatingly.Rotatablely move and produce circumferential velocity V1, crank motion produces yarn guiding speed V2, doff speed of production: V=(V12+V22) 1/2, and tg α=V2/V1; α is called yarn circle winding angle and claims again yarn circle spiral angle, is one of principal parameter of design winding mechanism.By " speed of production " and " intersection angle (2 α) " thus just can obtain reeling V1 and yarn guiding speed V2 calculate the control rate of friction roller motor inverter and groove drum frequency converter.Adopt Frequency Converter Control friction roller motor and groove drum, can realize motor speed and regulate.The technical program can be passed through software modification " intersection angle (2 α) ", thereby meets the production requirement of multiple yarn.
To the anti-stacked design in winding process.Bobbin is when reeling, and around the yarn circle reply of top cylinder sub-surface, the yarn circle before it had certain displacement amount afterwards for each.Like this, yarn circle will be evenly distributed in the surface of bobbin.But if the displacement of yarn circle is when just equal zero, be that the angle of displacement of yarn circle is when equal zero, so, still in guide cycle last time, on the yarn circle position on bobbin surface, this phenomenon is just called the overlapping coiling of yarn circle around the yarn circle of top cylinder sub-surface rear guide cycle.On bobbin, rough overlapping band makes bobbin and cylinder bad contact, and the yarn of bossing is subject to excessive friction damage, causes rear manufacturing procedure Yarn break, the fluffing of yarn body.Overlapping sliver can cause that Winding Density of Cheese is irregular, and bobbin coiling capacity reduces.During the unwinding yarn of overlapping bobbin, because yarn embeds or closely stacking mutually, so that unwinding resistance increment, also can produce knocking over and ravellings.Overlapping too serious bobbin will hinder dye liquor infiltration, so that uneven dyeing.It is overlapping that this control system adopts periodically-varied groove drum rotating speed mode to prevent, contains the ARM chip controls frequency converter of Cortex-M3 kernel by High Performance, adopts random algorithm, and effect is well controlled.By revising " perturbation amplitude " and " disturbance cycle " parameter at this interface, change anti-stacked effect.
In above-described embodiment, unaccounted content is prior art, therefore this place repeats no more.
The foregoing is only one embodiment of the present of invention, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
