Detailed description of the invention
Fig. 1 is axonometric chart of the present utility model.Fig. 2 is front view of the present utility model.As shown in Figure 1 and Figure 2, this practicality
Novel include silk pressing rod 2, around yarn axle 1 and reciprocating apparatus 4.Silk pressing rod 2 is fixed on around yarn axle 1 side, is fixed with cylinder on yarn axle 1
Pipe spindle, reel 10 is axially inserted on Spulspindelspulspindel.Silk pressing rod 2 contacts with reel 10, and edge is tangent.Reciprocating apparatus 4 is installed
In below yarn axle 1, its direction of motion is paralleled with the axial direction around yarn axle 1.It is additionally provided with cable guiding device 3, cable guiding device 3 upper end
It is provided with broken thread detector 5.
The increase of reel 10 diameter, or rotating continuously or being mended by the vertical movement of backer roll 8 by Spulspindelspulspindel
Repay.Nevertheless, when reaching the final diameter of reel, can be by full reel freely overhanging axially through Spulspindelspulspindel
End is taken off, and changes the reel in overhead.
Also include the first converter 6 and the second converter 7.First converter 6 controls the first motor, the output of the first motor
End controls around yarn axle 1；Second converter 7 controls the second motor, and the outfan of the second motor controls silk pressing rod 2 at vertical direction
On do frequency change wobble frequency rotate.The wobble frequency of silk pressing rod rotates finger pressure silk rod from top to bottom, or from upper again to the fortune of lower rotation
Dynamic, and the linear velocity of silk pressing rod is by around the dynamic decision of yarn axial compression crossed belt.
Fig. 3 is the wiring diagram of converter.The operating port of the first converter and the operating port of the second converter are connected to
After together, by the first switch ground connection.The stopping port stopping port and the second converter of the first converter links together
After, by second switch ground connection.First converter and the second converter all have time Protection Counter Functions；The time of the first converter
After the time clearing operating port of clearing port and the second converter links together, by the 3rd switch ground connection.
Coiling spindle is placed on reciprocating apparatus 4, does reciprocal fortune by reciprocating apparatus 4 transverse to yarn direct of travel
Dynamic, pass sequentially through cable guiding device 3 and broken thread detector 5 afterwards, guide through the silk pressing rod 2 rotated, be wrapped on reel 10；
Being additionally provided with magnet steel on silk pressing rod 2, magnet steel is a groove on silk pressing rod, is used for producing photoelectric pulse signal, function with turn
Speed meter is identical, whenever going to magnet steel, will produce a signal, and the pulse collection port of magnet steel and the first converter 6 is connected；
Broken thread detector 5 simultaneously with burn out detection signal port and the burn out detection signal end of the second converter 7 of the first converter 6
Mouth is connected.
This bobbin-winding machine is controlled to run by the first converter 6 and the second converter 7, and the first converter 6 controls to carry out around yarn axle 1
Around yarn, the second converter 7 drives the axle of silk pressing rod 2 to make wobble frequency operating, around excellent 2 pressings of yarn axle 1 and silk pressing to drive silk pressing rod 2 etc.
Linear velocity rotates, and the speed command around yarn axle 1 is set by the first converter 6 parameter, and as the order of speed by PID regulation
Value, carries out the PID regulation of speed.After setting linear velocity on yarn axle 1, this linear velocity is as the aim parameter of PID, by silk pressing rod
2 magnet steel above give pulse signal, and as the feedback signal of PID, this pulse signal delivers to the first converter 6, carries out speed
PID/feedback, the rotation of silk pressing rod 2 simultaneously is driven by the second converter 7, make wobble frequency operating, reach the purpose uniformly around yarn.
Simultaneously because be provided with broken thread detector 5, broken thread detector 5 can sense tension signal, the first converter 6
Have broken yarn detection real-time monitoring and control with the second converter 7, once have broken yarn signal, then the tension force of yarn once changes, vertical
I.e. feeding back to two inverter input, converter is shut down and display alarm information.
Spindle forming process is to be formed by stacking by two independent motions: constant speed rotary motion and reciprocating motion.By 2
The superposition of individual motion, yarn forms diamond-mesh movement locus on low cylinder surface.If two motions are all uniform motion, then gesture
Bulge must be formed in yarn intersection.As being intended to upset the intersection point of every layer, reciprocating speed can be made to change constantly, i.e. second becomes
Frequently device increases wobble frequency function, then this problem just can be satisfactorily resolved.Fig. 4 is the schematic diagram of the wobble frequency function of converter.Can
FREQUENCY CONTROL is done with reference to wobble frequency image as shown in Figure 4.When the first switch Guan Bi, after the operating port of two converters is connected,
Converter brings into operation, and just starts to do wobble frequency control after converter output frequency has arrived the mid frequency in Fig. 4.Accelerating
During to mid frequency process, the acceleration time of converter is setting value.When converter wobble frequency controls invalid, or under halt instruction
After reaching, the deceleration time of converter is setting value.When in wobble frequency operating range, then Acceleration and deceleration time is according to the wobble frequency rise time
Setting value with wobble frequency fall time.Its action is as shown in Figure 4.It addition, the frequency variation scope that wobble frequency controls is still by converter
Frequency limits limits, and when i.e. (mid frequency+wobble frequency amplitude) is more than upper frequency limit value, operates with upper frequency limit, (center frequency
Rate-wobble frequency amplitude) less than lower-frequency limit value time, with lower-frequency limit operate.
Above-described is only preferred implementation of the present utility model, and this utility model is not limited to above example.Can
To understand, those skilled in the art directly derive or associate on the premise of without departing from spirit of the present utility model and design
Oher improvements and changes, within being all considered as being included in protection domain of the present utility model.
