Above-mentioned is just the introduction about the construction of each device in the present invention.It should be noted that, in the present invention, the duty of each device is with order by automatic controlling system, and namely when power source provides power, provides great power by automatic controlling system.Now only for the cooperation between each apparatus structure, the course of work of the present invention is described in detail, specific as follows:
The present invention realizes the winding to bobbin filling by two operations.First operation is that yarn is guided to target location between bobbin and bobbin cradle from yarn outlet; Second operation work is wound on bobbin by yarn, forms filling.
The guiding of yarn:
As shown in figure 15, after spinning machine doffs, the swing arm 102 of drive unit driving mechanical arm 1 and master cylinder 104 upwards lift simultaneously.When master cylinder 104 is a little more than operating position, drive unit stops driving.Now, as shown in figure 16, active cylinder stretches out piston rod, suction nozzle 201 is suspended from the top of yarn outlet.As shown in figure 17, drive unit drives master cylinder 104 to rotate, and realizes locating on spinning machine, the sensing yarn outlet position making suction nozzle 201 accurate and stable by the locating piece 206 below suction nozzle 201.Meanwhile, start negative pressure device, yarn 11 is sucked yarn road by yarn outlet by suction nozzle 201, finally enters refuse yarn case.After yarn 11 is obtained by suction nozzle 201, drive unit is carried on master cylinder 104, and locating piece 206 and spinning machine are departed from, and the piston rod of master cylinder 104 is retracted simultaneously.As shown in figure 18, after the piston rod of master cylinder 104 bounces back completely, drive unit drives swing arm 102 to rotate, until two locating wheels on cylinder block 103 501 and frame 8 overlap for spacing two pins.Now, mechanical arm 1 completes location, locus, and namely suction nozzle 201 has pointed to the target location between bobbin 10 and bobbin cradle.It should be noted that, in the process that mechanical arm 1 rotates, being drawn downward yarn 11 by suction nozzle 201 can enter in thread-carrier 3 along the inclination guide arm 305 of lower floor's thread-carrier 302.Meanwhile, yarn 11 enters into section yarn device 4 that sheared edge is opened.Though suction nozzle 201 shown in Figure 18 is determined with the relative position of bobbin 10, but yarn 11 still and between bobbin 10 leaves little segment distance.As shown in figure 19, master cylinder 104 slightly extends to bobbin 10 direction, makes yarn 11 enter into the target location of bobbin 10 greatly between end and bobbin cradle.After yarn 11 puts in place, bobbin cradle 9 closed pair yarn 11 is implemented to accommodate.So far the present invention completes the guiding to yarn 11.
The winding of filling:
As shown in Figure 7, yarn 11 is slipped in thread-carrier 3 by the inclination guide arm 305 of lower floor's thread-carrier 302.Now, the appearance yarn chamber of upper strata thread-carrier 301 and the yarn guiding trough 306 of lower floor's thread-carrier 302 and to hold between yarn chamber be path.As shown in Figure 8, the piston rod of assistant cylinder 105 stretches out forward, and the yarn guiding trough 306 of lower floor's thread-carrier 302 is closed by the revers turn part 304 of upper strata thread-carrier 301.Upper and lower two appearance yarn chambeies overlap to form a closed thread guide eyelet 307, and yarn 11 is constrained in thread guide eyelet 307.Simultaneously, drive unit drives bottoming yarn friction roller 6 near bobbin 10, until friction roller 606 and bobbin 10 surface contact.Under the drive of frictional force, bobbin 10 starts to rotate.Yarn 11 just under the constraint of thread guide eyelet 307, bobbin 10 can be wound parallel filling, as in Fig. 8 shown in B.As shown in figure 20, while the piston rod of assistant cylinder 105 stretches out forward, the bottom knife 404 cutting yarn device 4 is also pushed out, and top blade 405 rotates under the restriction of actuating arm 409.The sheared edge of cutting yarn device 4 closes, and the yarn 11 below bobbin 10 and between suction nozzle 201 is truncated, and yarn 11 is inhaled in the refuse yarn case of negative pressure device.11, yarn above bobbin 10 and between thread-carrier 3 is by being wound on bobbin 10 of continuing.After filling winding quantity reaches standard, the piston rod of assistant cylinder 105 is retracted, and thread guide eyelet 307 disappears, and also removes the constraint of yarn 11 simultaneously.Mechanical arm 1 is raised to initial position by drive unit, as shown in figure 21.Drive unit also can drive bottoming yarn friction roller 6 away from bobbin 10.Yarn 11 recovers the state of normal spinning.So far, filling winding working procedure of the present invention completes.
In sum, the present invention eliminates requisite joint operation in prior art, and corresponding also eliminates piecing devices.Not only simplify device structure, reduce equipment cost, and simplify the flow process of bottoming yarn, the winding efficiency of filling is improved.In addition, be wound filling because yarn directly guides on bare bobbin by the present invention, so avoid the generation of yarn and the inconsistent situation of filling quality on same bobbin, decrease the joint quantity of yarn, and then ensure the fabric quality of follow-up spinning.
