Description

Technical Field

[0001] The present application belongs to the technical field of glass fiber production, and specifically relates to a crawler-type yarn support disc for automatic yarn unloading. Background Art

[0002] In the process of glass fiber drawing, the high labor intensity and harsh environment of drawing work have caused a labor shortage. Although some large enterprises have used yarn unloading robots to remove yarn balls from the drawing machine head one by one and put them on the yarn car to reduce some workload, the multi-slide telescopic mechanism is huge and complex, the rotation space is large, and the overall inverted mechanism is unstable and swaying. It is not suitable for the one-time unloading of all yarn balls in four-point drawing and five-point drawing, and it is impossible to cut and separate the inner and outer layers of the connecting yarn between the yarn balls. It must be cut and separated manually before it can be put on the yarn car. Such human-machine cooperation has safety hazards. In order to solve the problems of improving production efficiency and automation level of existing factories and safety hazards, robots and yarn trays that can automatically complete yarn unloading, yarn cutting and yarn placement have become the focus of industry research and development. Utility Model Content

[0003] In view of this, the present application provides a crawler-type yarn support plate for automatic yarn unloading to solve all or part of the technical problems described in the background technology section of the present application.

[0044] See also Figure 1-Figure 8 The crawler-type yarn support plate for automatic yarn unloading disclosed in the present application includes a crawler bracket 10, a first crawler assembly 20, a second crawler assembly 30 and a yarn breaking device 40.

[0045] The track carrier 10 includes a first track carrier 110 and a second track carrier 120 .

[0046] The first track assembly 20 includes a first track 210 , a first track roller 220 , and a first driving group 230 .

[0047] The second track assembly 30 includes a second track 310 , a second track roller 320 , and a second driving group 330 .

[0048] The first crawler 210, the first crawler roller 220, and the first drive group 230 are arranged on the first crawler bracket 110, and the first crawler 210 can rotate under the action of the first crawler roller 220 and the first drive group 230. The number of the first crawler rollers 220 can be flexibly configured according to the length of the first crawler 210, and at least one driving roller and one driven roller are included. The first drive group 230 preferably adopts a driving motor. The power output shaft of the driving motor is connected to the rotating shaft of the first crawler roller 220. By controlling the driving motor, the rotation direction of the first crawler roller 220 and the conveying direction of the first crawler 210 can be controlled.

[0049] The second crawler 310, the second crawler roller 320, and the second drive group 330 are arranged on the second crawler bracket 120, and the second crawler 310 can rotate under the action of the second crawler roller 320 and the second drive group 330. The number of the second crawler rollers 320 can be flexibly configured according to the length of the second crawler 310, and at least one driving roller and one driven roller are included. The second drive group 330 preferably adopts a driving motor. The power output shaft of the driving motor is connected to the rotating shaft of the second crawler roller 320, and the rotation direction of the second crawler roller 320 and the conveying direction of the second crawler 310 can be controlled by controlling the driving motor.

[0050] The yarn cutting device 40 is disposed between the first crawler assembly 20 and the second crawler assembly 30 , and is used to cut off the connection between the yarn group carried on the first crawler 210 and the yarn group carried on the second crawler 310 .

[0051] The length of the second crawler 310 is greater than that of the first crawler 210. The first crawler 210 is used to place the yarn balls carried thereon after the yarn is broken onto the hook of the yarn cart, and the length of the first crawler 210 is based on the ability to carry one yarn ball. The length of the second crawler 310 can be set according to the situation of the wire drawing machine that needs to take the yarn. For example, when the wire drawing machine that needs to take the yarn at one time is a four-point drawing machine (there are four yarn balls that need to be taken out in parallel on the head shaft of the wire drawing machine), the length of the second crawler 310 is based on the ability to carry three yarn balls in parallel. Together with the first crawler 210, four yarn balls can be taken out at one time.

[0052] The yarn breaking device 40 includes a yarn breaking cutter roller 410, a yarn breaking blade 420, and a cutter roller driving assembly 430. The cutter roller driving assembly 430 includes a rack 431, a gear 432, and a cutter roller driving cylinder 433. The yarn breaking blade 420 is arranged on the yarn breaking cutter roller 410, the rack 431 is connected to the piston rod of the cutter roller driving cylinder 433, the gear 432 is fixed to the cutter roller shaft of the yarn breaking cutter roller 410, and the rack 431 and the gear 432 are meshed with each other. The gear 432 can rotate under the action of the rack 431 and the cutter roller driving cylinder 433 to drive the yarn breaking cutter roller 410 to rotate together.

[0053] Description of the yarn unloading and yarn breaking process: Taking the four-part drawing as an example, the crawler-type yarn support disk is driven to the main shaft of the wire drawing machine, and the first crawler 210 and the second crawler 310 are aligned with the yarn balls, and the yarn balls are lifted up to carry four yarn balls on the yarn support disk at one time. When the yarn is broken, the piston rod of the knife roller driving cylinder 433 is telescopically moved, driving the rack 431 to make a linear motion, and then driving the gear 432 and the yarn breaking knife roller 410 to rotate synchronously, and the yarn breaking blade 420 cuts off the connection between the yarn ball on the first crawler 210 and the adjacent yarn ball placed on the second crawler 310. After the yarn ball placed on the first crawler 210 after the yarn is broken is released (after being hung on the hook of the yarn car), the second crawler 310 transports the yarn ball in the direction of the first crawler 210, and repeats the above-mentioned yarn breaking and yarn releasing steps until the yarn breaking and yarn releasing of all yarn balls are completed.

[0054] In some applications, it is necessary to measure the weight of the yarn ball placed on the yarn carrier. Therefore, in a modified embodiment of the present application, the crawler-type yarn support plate for automatic yarn unloading further includes a weighing mechanism 50, which includes a weighing cylinder 510, a weighing meter 520, and a weighing plate 530. The weighing cylinder 510 is arranged at the lower part of the first crawler 210, and the weighing meter 520 and the weighing plate 530 are arranged at the empty part in the middle of the first crawler (see Figure 3 ).

[0055] The weighing scale 520 is arranged on the piston rod of the weighing cylinder 510, and the weighing plate 530 is arranged on the weighing scale 520. The weighing scale 520 and the weighing plate 530 can move up and down under the action of the weighing cylinder 510. Before the yarn is put down, the weighing cylinder 510 is started to drive the weighing scale 520 and the weighing plate 530 to lift the yarn on the first crawler 210 for weighing. After the weighing is completed, the weighing cylinder 510 drives the weighing scale 520 and the weighing plate 530 to descend and reset.

[0056] The above-mentioned empty space or weighing area can be formed by the following configuration: the two first crawlers 210 are respectively arranged in parallel on the first crawler bracket 110 or the pallet slide 60, a weighing area for installing a weighing mechanism is formed in the middle of the two first crawlers 210, and the weighing plate 530 is arranged in the weighing area between the two first crawlers 210, that is, in the empty space, and the upper surface of the weighing plate 530 is lower than the lower edge of the first crawler 210.

[0057] When the line between the yarn group on the first crawler 210 and the adjacent yarn group placed on the second crawler 310 is long or the yarn group is far from the yarn breaking blade 420, it is necessary to add a yarn breaking rubber roller 440 and a yarn breaking actuator 450 to ensure the yarn breaking efficiency. Figure 8The yarn-breaking rubber roller 440 is used to press the yarn to be cut onto the yarn-breaking knife roller 410, and the yarn-breaking actuator 450 is used to drive the yarn-breaking rubber roller 440. The yarn-breaking rubber roller 440 and the yarn-breaking actuator 450 are arranged above the yarn-breaking knife roller 410. When the yarn needs to be cut, the yarn-breaking actuator 450 drives the yarn-breaking rubber roller 440 to press down and press the yarn ball connection line onto the yarn-breaking knife roller 410. Then, the yarn-breaking knife roller 410 rotates, and the yarn-breaking blade 420 cuts the yarn ball connection line. Figure 8 As shown, the yarn breaking rubber roller 440 and the yarn breaking actuator 450 are arranged on the upper part of the yarn breaking knife roller 410 through the rubber roller bracket 70, and the yarn breaking rubber roller 440 and the yarn breaking actuator 450 can also be fixed on other structures. When the yarn needs to be broken, the crawler-type yarn supporting plate is moved to the lower part of the yarn breaking rubber roller 440 or the yarn breaking rubber roller 440 and the yarn breaking actuator 450 are moved to the upper part of the yarn breaking knife roller 410.

[0058] See also Figure 8 In another preferred embodiment of the present application, the crawler-type yarn supporting disc disclosed in the present application further includes a tray slide 60. The first crawler bracket 110 and the second crawler bracket 120 are both arranged on the tray slide 60, the first crawler assembly 20 and the second crawler assembly 30 are respectively arranged on the first crawler bracket 110 and the second crawler bracket 120, and the yarn breaking device 40 is arranged between the first crawler 210 and the second crawler 310. Through the tray slide 60, the crawler-type yarn supporting disc can be connected to a motion driving mechanism such as a screw slide module to realize automatic control of the crawler-type yarn supporting disc.

[0059] It should be particularly noted that the track bracket 10 can adopt a split structure (including the first track bracket 110 and the second track bracket 120 as mentioned above), or an integrated structure, the first track assembly 20 and the second track assembly 30 are both arranged on the track bracket 10, and the yarn breaking device 40 is arranged between the first track 210 and the second track 310.
