The specific working process of the invention is as follows:
Yarn supporting action:
The worker moves the yarn carrier communication servo 3 integrally to the spindle car by the moving device 1, and as shown in fig. 2, releases the fixation of the positioning 4010 and the bracket 4015, moves the upper mounting plate 4016 to the spigot of the opening 40151, and allows the upper mounting plate 4016 to rest on the spigot. The worker marks the numbered spindle on the spindle car to remove the yarn head, winds the yarn head around the yarn guide ring 4031 and then passes through the open slot on the lower tension frame 4012, finally passes through the space between the two magnetic sheets 4022, the adjacent abutted magnetic sheets 4022 are positive and negative magnetic sheets, and the adjacent magnetic sheets are adhered to the adhesive strip 4028 after passing through the open slot. The erection time of each yarn is 1s, each spindle is erected by the method, after all the spindles are erected, the upper mounting plate 4016 is put down in the direction shown by the arrow in fig. 2, meanwhile, the position of the lower mounting plate 4016 is fixed through the locating plate 4010, the springs 4018 extend under the influence of gravity and enable the lower tension plate 4019 to pass through the lower tension frame 4012, and the yarn heads penetrate out from the gap between the lower tension plate 4019 and the lower tension frame 4012.
Yarn moving action:
The worker moves the yarn holding device, the servo device 3 and the moving device 1 to the vicinity of the yarn pressing and splicing device 5, and starts the electromagnetic chuck 202 to have magnetic attraction force to firmly attract the magnetic plate 201, so that the yarn pressing and splicing device 5 and the moving device 1 cannot be separated.
Next, as shown in fig. 6, the worker manually controls the servo device to move, and the second slider 303 is linearly displaced along the second slider 302 to bring the first slider 304 close to the yarn splicing device 5, and in this process, the first slider 304 is locked with the second slider 305 by the lock lever 306. As shown in fig. 1, 2 and 6, when the first sliding plate 304 slides to the limit position, the locking of the locking lever 306 is released, the second sliding plate 305 is moved, so that the yarn clamping device 402 clamped on the second sliding plate 305 moves to the frame 503 (as shown in fig. 9) as a whole, the worker removes the yarn clamping device 402, then the first positioning block 4027 at the bottom of the yarn clamping bottom plate 4025 is embedded into the opening of the second positioning block 524, and the yarn clamping device 402 is clamped in the frame 503 under the action of the elastic top block 5241.
At this time, the worker closes the electromagnetic chuck 202, and pushes the moving device 1 together with the servo device 3 in a reverse direction, so that all yarns horizontally and parallelly span right above the crimping and splicing device 5.
Yarn pressing and pushing actions:
Yarn pushing when the yarn spans over the splicer 508 in the crimp splice device 5, as shown in fig. 9 to 11, because the spacing between adjacent yarns is large and the yarns may not enter the splicer 508, as shown in fig. 7 to 9, the worker inputs a control command in the PLC console 502, the first stepper motor 519 receives the command and controls the first screw 504 to rotate, the first screw nut 505 moves axially along the first screw 504 to move the movable base 506 between the yarns, as shown in fig. 12, during which the push rod 528 contacts one of the yarns and pushes the yarn closer to the other yarn, causing the two yarns to come into close proximity and lie over the splicer 508.
In order to meet the requirement of splicing two yarns in the splicer 508, as shown in fig. 8 to 11, the PLC control console 502 sends out an instruction, the air cylinder 512 is started to drive the movable plate 514 to move downwards relative to the vertical plate 525, and the pressing plates 511 are respectively fixed on the left side and the right side of the movable plate 514, so that the pressing plates 511 also move downwards, and the pressing plates 511 contact the two yarns in the descending process and press the two yarns into the twisting joints of the splicer 508.
Color marking, as shown in fig. 12, in the process of descending the thread pressing plate 511, since one side of the movable plate 514 is fixedly connected with the pressing block mounting plate 529, the pressing block 530 descends along with the movable plate 514, and the pressing block 530 descends to contact with the yarn and press the yarn into the ink box 532 for coloring, thereby realizing the segmented color marking of each yarn, and enabling the segmented color marking to be seen on the final whole continuous cylindrical braid to correspond to the spindle.
The second step motor 520 works after the splicing is in place, and the mechanical transmission of the flange coupler 518, the bearing 517 and the first elastic coupler 516 is used for completing the sequential rotary splicing (knotting), in the process, the untwisting and broken end cutting of two yarns in a splicing cavity are mainly realized, the yarn pressing action is reset after the splicing is completed, meanwhile, the PLC control console 502 controls the first screw nut 505 in the servo slipway to advance to a station for the next splicing, and the yarn passes through the yarn fixer 510 after the yarn splicing is completed and then penetrates into the dyeing test braiding machine.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
