Description

Technical Field

[0001] The invention relates to the technical field of yarn winding, and in particular to a quantitative winding device based on flexible yarn processing and a winding method thereof. Background Art

[0002] After the yarn is processed by the spinning equipment, it usually needs to be reeled in by the winding equipment, and the reeled yarn is transferred to the bobbin rack for subsequent spinning, etc. In order to ensure that the thickness of the yarn to be wound on the drum meets the requirements of relevant customers or subsequent production, it is usually necessary to test the yarn to be wound on the drum.

[0003] Publication No. CN114148817A discloses a flexible yarn conveying device and a flexible yarn quantitative winding device having the same. The problem raised in the background technology is: At present, the detection of the thickness of the yarn wound on the reel is generally carried out separately, and it is necessary to wind it after the detection, which increases the workload and reduces the yarn sorting efficiency. The first end is located on the side of the support shaft away from the thickness detection device so that the thickness detection device can detect the thickness of the flexible yarn wound on the support shaft, thereby detecting the thickness of the yarn during the process of conveying the yarn.

[0004] Based on the existing technology, there are the following problems:

[0005] Although the existing technology can detect the thickness of the yarn multiple times, due to the softness of the yarn itself, external force will cause the yarn itself to deform, thereby affecting the accuracy of the yarn thickness detection, and there is uncertainty about the location of the abnormal thickness of the yarn. Even if multiple tests are performed, there is still a risk of missed detection, thereby reducing the metering effect. Moreover, the existing technology usually transfers the wound bobbin to a conveying mechanism, which is then conveyed to the bobbin rack by the conveying mechanism, or although there is a device that directly transfers the wound bobbin of the yarn directly to the bobbin rack, it is not convenient to measure the yarn, and it is not convenient to limit the bobbin placed on the bobbin rack. In the subsequent weaving process, the bobbin is prone to fall, affecting the subsequent production efficiency. Summary of the invention

[0006] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a quantitative winding device and a winding method based on flexible yarn processing, which detects whether the yarn is obviously too thin or too thick by measuring the thickness and weight of the yarn after winding, so as to complete the measurement of the yarn winding, and improves the stability of the bobbin of the wound yarn after it is transported, so as to facilitate subsequent textile production.

[0035] S1: After the winding device winds the yarn on the bobbin, the bobbin with the wound yarn is transported to the bobbin rack through the transfer mechanism;

[0036] S2: During the process of conveying the bobbin in the above step S1, the weight of the yarn is measured by the second measuring mechanism to determine the amount of the wound yarn;

[0037] S3: When the bobbin of the wound yarn is transported to the bobbin rack, the bobbin of the wound yarn is limited by the cooperation of the trigger mechanism and the placement mechanism to prevent the bobbin from falling from the bobbin rack.

[0038] The present invention provides a quantitative winding device and a winding method based on flexible yarn processing. Compared with the prior art, the device has the following beneficial effects:

[0039] 1. The present invention uses the first metering mechanism and the second metering mechanism to judge whether the yarn is too thick, too thin or abnormally wound from the thickness of the yarn winding and the weight of the yarn, thereby improving the accuracy and stability of winding metering. The trigger mechanism and the placement mechanism cooperate to limit the position of the bobbin placed on the bobbin rack to prevent it from falling during subsequent prevention and control production processes, thereby improving production stability.

[0040] 2. When the present invention transfers bobbins of different shapes (such as truncated cone-shaped bobbins), the inner wall of the truncated cone-shaped bobbins is designed to be inclined. In this case, the first metering mechanism can be used for metering detection, thereby increasing the flexibility of metering. The first metering mechanism is used to measure according to the thickness of the yarn winding, and the metering position can be adjusted to be suitable for metering yarns of different winding thicknesses. The quantitative component is used to directly measure the bobbin and the yarn wound on the surface of the bobbin, thereby improving the accuracy of metering.

[0041] The metering component is always located at the middle end of the wire reel, thereby improving the metering stability and being applicable to wire reels of different lengths, thereby improving the applicability.

[0042] 3. The present invention uses an air bag or the like to clamp and fix the wire bobbin through the clamping mechanism, which is suitable for wire bobbins of different shapes and improves applicability. While the two sides and the top of the air bag are limited by the first limit assembly and the second limit assembly, when the air bag is unclamped, the air bag is relatively attached to the surface of the first mounting seat to avoid contact with the inner wall of the wire bobbin, thereby avoiding affecting the stability and accuracy of weight detection.

[0043] 4. The present invention moves the bobbin of wound yarn together with the trigger mechanism, and the second rod of the trigger mechanism is movably arranged, so that when the bobbin of wound yarn is placed on the bobbin rack, the second rod presses the abutment plate, thereby driving the third rod to move downward, which is convenient for placing the bobbin, and after the placement is completed, under the action of the third spring and the second spring, the third rod moves upward, thereby facilitating the limiting of the bobbin of wound yarn to prevent it from falling and facilitating subsequent disassembly.

[0071] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] Example 1: Please refer to Figure 1 , Figure 2 , Figure 4 and Fig.11 , a quantitative winding device based on flexible yarn processing, comprising a winding device 1, a bobbin rack 3 and a transfer mechanism 2 arranged between the winding device 1 and the bobbin rack 3 for transferring yarn, and also comprising a placement mechanism 4 arranged on the side wall of the bobbin rack 3 for placing the bobbin, a second metering mechanism 7 arranged at the transfer end of the transfer mechanism 2 and used for monitoring the yarn weight, and a trigger mechanism 8 cooperating with the placement mechanism 4 to limit the bobbin, the second metering mechanism 7 comprising a second mounting seat 71 and a metering assembly 72 arranged on the top of the second mounting seat 71;

[0073] See also Fig.14 , the metering component 72 includes:

[0074] The first shell 721 is fixedly arranged on the top of the second mounting seat 71 and extends into the second mounting seat 71. The first electromagnet 726 is fixedly sleeved on the inner wall of the bottom of the first shell 721. The second electromagnet 725 is sleeved on the inner wall of the first shell 721. The first electromagnet 726 and the second electromagnet 725 are sleeved on the inner wall, and the sides where the first electromagnet 726 and the second electromagnet 725 are close to each other are the same poles. The top of the second electromagnet 725 is fixedly provided with a first rod 724 extending to the top of the first shell 721. The top of the first rod 724 is fixedly provided with a bearing plate 723. The top of the bearing plate 723 is fixedly provided with a weight sensor 722. The side wall of the first rod 724 and located between the second electromagnet 725 and the top inner wall of the first shell 721 is sleeved with a first spring for resetting the weight sensor 722.

[0075] A first through hole for sleeve-mounting the first rod 724 is formed on the top of the first housing 721 to limit the movement of the first rod 724 .

[0076] In a specific implementation, after the clamping mechanism 6 removes the winding drum of the wound yarn from the winding device 1 and stably clamps it, the weight sensor 722 of the metering assembly 72 first contacts the top inner wall of the winding drum of the wound yarn to ensure the stability of the winding drum after the clamping mechanism 6 cancels the clamping.

[0077] When the quantitative component is specifically operated, the first electromagnet 726 and the second electromagnet 725 are started. Since the first electromagnet 726 and the second electromagnet 725 are close to each other on the same side, the repulsive force generated after power is turned on drives the first rod 724, the bearing plate 723 and the weight sensor 722 to move vertically so as to contact the top of the inner wall of the bobbin. Then, the clamping and fixing of the bobbin by the clamping mechanism 6 is cancelled so that the bobbin is supported on the top of the weight sensor 722, so as to detect the weight of the yarn. The weight of the yarn is the weight detected by the weight sensor 722 minus the weight of the bobbin itself, or the weight range of the bobbin and the yarn as a whole is directly preset to facilitate judgment whether there is any abnormality in the weight.

[0078] The weight sensor 722 is in direct contact with the inner wall of the bobbin to perform weight detection and improve the accuracy of the detection. After the detection is completed, the first electromagnet 726 and the second electromagnet 725 are powered off, and then, under the action of the first spring, the weight sensor 722 and the supporting plate 723 are reset to facilitate the next detection.

[0079] See also Fig.11 and Fig.12 The second metering mechanism 7 further includes an adjusting component 73 for adjusting the position of the metering component 72, and the adjusting component 73 includes:

[0080] The adjusting plate 734 is fixedly arranged on the side of the first mounting seat 62 away from the connecting seat 52. The side of the adjusting plate 734 away from the first mounting seat 62 is fixedly provided with guide rods 733 arranged in a circular array. The side of the second mounting seat 71 close to the first mounting seat 62 is provided with a guide groove adapted to the guide rod 733, and the guide groove is sleeved on the side wall of the guide rod 733. The side of the adjusting plate 734 close to the second mounting seat 71 and located on the inner side of the guide rod 733 is fixedly provided with a threaded seat extending into the second mounting seat 71;

[0081] The screw rod 731 is rotatably disposed at the center of the second mounting seat 71 and is threadedly connected to the inner wall of the threaded seat;

[0082] The mounting groove 732 is formed at the top of the second mounting seat 71 and the third mounting seat 81 to leave space for the operating screw 731 to rotate.

[0083] In a specific implementation, the screw rod 731 is rotated. Since the screw rod 731 is rotatably connected to the second mounting seat 71 and is threadedly connected to the threaded seat, the second mounting seat 71 and the third mounting seat 81 are driven to move horizontally during the rotation of the screw rod 731 under the limitation of the guide rod 733 and the guide groove, so as to adjust the position of the metering component 72 so that the metering component 72 is always located at the middle end of the bobbin, thereby improving the metering stability and being applicable to bobbins of different lengths, thereby improving the applicability.

[0084] The installation through slot 732 is provided to facilitate the rotation of the screw rod 731 from the top of the second installation seat 71 and the third installation seat 81, thereby facilitating practical operation.

[0085] See also Figure 5 and Figure 6 , the first metering mechanism 5 comprises:

[0086] A connecting seat 52 is fixedly arranged on the side wall of the telescopic shaft of the electric push rod 25. A side of the connecting seat 52 away from the electric push rod 25 is provided with distance measuring sensors 53 arranged movably and at intervals. A side of the connecting seat 52 away from the electric push rod 25 is provided with a driving structure 54 for driving the distance measuring sensors 53 to move closer to or away from each other.

[0087] The connecting plate 51 is fixed at the center of the connecting seat 52 and is located on the side of the connecting seat 52 away from the electric push rod 25. The side of the connecting plate 51 away from the connecting seat 52 is located on the outside of the side of the distance measuring sensor 53 away from the connecting seat 52, so that there is a distance between the distance measuring sensor 53 and the bobbin.

[0088] In a specific implementation, since the surface of the bobbin is wound with a specified number of turns of yarn, a certain thickness is accumulated on the surface of the bobbin, and the distance from the distance sensor 53 to the yarn is detected to determine the thickness of the yarn;

[0089] When the first metering mechanism 5 is specifically operated, the position of the distance sensor 53 is adjusted through the driving structure 54 according to the number of turns of the bobbin, so that the distance sensor 53 is exactly located at the position of the normal winding yarn thickness. When the value detected by the distance sensor 53 is too large, it means that the winding thickness has not been reached, that is, the yarn is obviously too thin. When the value detected by the distance sensor 53 is normal, the distance sensor 53 is driven by the driving mechanism to move to the side away from the connecting plate 51, so as to adjust the position of the distance sensor 53. When the value detected after the movement is still normal, it means that the winding thickness is too large, that is, the yarn is obviously too thick.

[0090] The driving mechanism includes a limit slide groove provided on one side of the connecting seat 52 close to the connecting plate 51, a limit slider placed in the limit slide groove and in mirror symmetry, and a bidirectional screw 731 rotatably connected to the connecting seat 52 and threadedly connected to the limit slider, and the limit slider is fixedly connected to the distance measuring sensor 53 to drive the distance measuring sensors 53 to move closer to or away from each other. By setting two distance measuring sensors 53, multi-point detection is provided to improve the measurement accuracy;

[0091] Through the cooperation of the first metering mechanism 5 and the second metering mechanism 7, it is judged whether the yarn is too thick, too thin or abnormally wound from the thickness of the yarn winding and the weight of the yarn, so as to improve the accuracy and stability of the winding metering. When transferring the bobbins of different shapes such as the truncated cone bobbins, the inner wall of the truncated cone bobbins is designed to be inclined, and the metering component 72 of the second metering mechanism 7 may be in an unstable contact with the inner wall of the bobbin. In this case, the metering detection can be performed by the first metering mechanism 5;

[0092] The winding of the yarn is measured by the first metering mechanism 5 or the second metering mechanism 7. Compared with the traditional method of passing the yarn through a designated detection position during transportation and limiting the detection section of the yarn by adsorption, the yarn itself is relatively soft and easy to deform, so the metering effect is better.

[0100] In a specific implementation, the airbag 61 is inflated to swell the airbag 61, so as to fix the wire tube from the inner wall of the wire tube. After the airbag 61 swells, it drives the rubber plate 641 and the fifth rod 644 to move, thereby improving the stability of the bulging support of the airbag 61, thereby improving the stability of the fixation.

[0101] Since the rubber plate 641 can be deformed to a certain extent, and the shape of the airbag 61 can be automatically adjusted according to the shape of the wire bobbin, so as to better fit the wire bobbins of different shapes, it is convenient to fix the wire bobbins of different shapes, and improve the applicability;

[0102] The first limiting assembly 63 is used to limit the two sides of the airbag 61 to prevent the airbag 61 from bulging to the two sides after swelling, so as to affect the stability of the airbag 61 swelling to the top to support and fix the bobbin. When the airbag 61 bulges, it drives the retaining ring 632, the fourth rod body 634 and the third limiting ring 633 to move, thereby limiting the two sides of the airbag 61.

[0103] While limiting the two sides and the top of the airbag 61 through the first limiting component 63 and the second limiting component 64, when the airbag 61 is unclamped, under the action of the sixth spring and the fifth spring, the retaining ring 632 and the rubber plate 641 are driven to move. Since the retaining ring 632 is made of elastic rubber material, the airbag 61 is relatively fitted to the surface of the first mounting seat 62 to avoid contact with the inner wall of the wire bobbin, thereby avoiding affecting the stability and accuracy of the weight detection.

[0106] Example 2: Please refer to Fig.11 and Fig.13 The technical solution of this embodiment is different from that of the first embodiment in that the trigger mechanism 8 includes:

[0107] The third mounting seat 81 is fixedly mounted on the outer wall of the second mounting seat 71 . The interior of the third mounting seat 81 is hollow. A movable second rod 82 is disposed inside the third mounting seat 81 .

[0108] The trigger mechanism 8 also includes:

[0109] The third electromagnet 84 is fixedly arranged on the inner wall of the third mounting seat 81, and the inner wall of the third mounting seat 81 is sleeved with the fourth electromagnet 83, the side where the third electromagnet 84 and the fourth electromagnet 83 are close to each other are the same poles, the side of the fourth electromagnet 83 away from the third electromagnet 84 is fixedly connected to an end of the second rod body 82 located in the third mounting seat 81, the side of the second rod body 82 away from the fourth electromagnet 83 extends to the outside of the third mounting seat 81, and the side wall of the third mounting seat 81 is provided with a second through hole for sleeved with the second rod body 82 to limit the movement of the second rod body 82, and the side wall of the second rod body 82 and located between the fourth electromagnet 83 and the inner wall of the third mounting seat 81 is sleeved with a second spring.

[0110] See also Fig.15 and Fig.16 , the placement mechanism 4 comprises:

[0111] A placement rod 41 is fixedly arranged on a side of the bobbin rack 3 close to the transfer mechanism 2. A first placement groove is provided at the lower end of the placement rod 41 away from the bobbin rack 3. A stop plate 44 is slidably arranged on the inner wall of the first placement groove so that the stop plate 44 can move horizontally along the first placement groove. An inclined surface 43 is arranged on the top of the stop plate 44. One side of the stop plate 44 located outside the first placement groove is bent upward to form a protruding structure 45. A second placement groove connected to the first placement groove is provided on the top of the placement rod 41, and the second placement groove is designed to be convex.

[0112] The third rod body 42 is sleeved in the second placement groove and extends to the top of the placement rod 41. The bottom of the third rod body 42 is designed to be hemispherical to cooperate with the inclined surface 43 to adjust the height of the third rod body 42 at the top of the placement rod 41. The lower end of the side wall of the third rod body 42 is fixedly sleeved with a first limiting ring 46 to limit the third rod body 42 from being separated from the second placement groove. A third spring is sleeved on the side wall of the third rod body 42 and located between the top of the first limiting ring 46 and the top inner wall of the second placement groove. A fourth spring is sleeved on the inner wall of the first placement groove and located on the side of the abutment plate 44 away from the protruding structure 45.

[0113] In a specific implementation, the third electromagnet 84 and the fourth electromagnet 83 are started, and a repulsive force is generated by the side where the third electromagnet 84 and the fourth electromagnet 83 are close to each other, thereby driving the fourth electromagnet 83 and the second rod 82 to move to squeeze the abutment plate 44. After being squeezed, the abutment plate 44 moves away from the third rod 42 through the inclined surface 43, so that the third rod 42 moves downward under the action of the third spring, so that the top of the third rod 42 is close to the placement rod 41, so that the bobbin of the wound yarn is stably sleeved on the side wall of the placement rod 41. When the bobbin of the wound yarn passes over the third rod 42, the third electromagnet 84 and the fourth electromagnet The magnet 83 is de-energized so that the bobbin of the wound yarn can continue to be placed on the placement rod 41. Due to the setting of the clamping mechanism 6 and the like, the bobbin of the wound yarn cannot completely pass over the third rod body 42. Therefore, after the bobbin of the wound yarn is partially placed on the placement rod 41, the clamping of the clamping mechanism 6 is canceled and the bobbin is moved away from the placement rod 41. Then, after adjusting the position, the bobbin is moved closer to the placement rod 41 so that the bobbin of the wound yarn completely passes over the third rod body 42, so that the bobbin on the placement rod 41 is limited by the third rod body 42 to prevent it from falling, and the bobbin can be removed later by manual pressing and the like.

[0114] The protruding structure 45 is provided to facilitate contact with the second rod body 82 , thereby facilitating the movement of the abutment plate 44 .

[0115] The carrying plate 723 and the rubber plate 641 are both designed to be arc-shaped so as to fit the inner wall of the wire barrel;

[0116] A fourth through hole for sleeve mounting the threaded seat and the screw 731 is provided on one side of the second mounting seat 71 close to the adjusting plate 734, and the fourth through hole is convex in design and communicated with the mounting through slot 732, so as to facilitate the actual rotation of the screw 731;

[0117] The third mounting seat 81 is located on a side of the second mounting seat 71 away from the first mounting seat 62 .

[0118] The first electromagnet 726 and other electronic components of the present invention are connected to an external power source and a controller through wires, which are all prior arts and will not be described in detail here.

[0119] The embodiment of the present invention further provides a winding method of a quantitative winding device based on flexible yarn processing, using a quantitative winding device based on flexible yarn processing, the method comprising the following steps:

[0120] S1: After the winding device 1 winds the yarn on the bobbin, the clamping mechanism 6 is extended into the inner wall of the bobbin of the wound yarn through the transfer mechanism 2, that is, the bobbin of the wound yarn is clamped and fixed by the clamping mechanism 6, and then the bobbin of the wound yarn is transported to the bobbin rack 3 through the transfer mechanism 2, and the clamping mechanism 6 is fixed from the inner wall of the bobbin by using the air bag 61, and the air bag 61 is easy to deform according to the shape of the bobbin, so as to fix the bobbins of different shapes such as truncated cones, thereby improving the applicability;

[0121] S2: In the process of transporting the bobbin in the above step S1, after the transfer mechanism 2 moves the bobbin of the wound yarn out of the winding device 1, the bobbin of the wound yarn is kept stable. In this process, the thickness of the yarn wound on the outer wall of the bobbin is detected by the first metering mechanism 5, so as to judge whether the thickness of the yarn meets the standard. Then, the weight sensor 722 of the second metering mechanism 7 moves upward and contacts the top of the inner wall of the bobbin of the wound yarn. Then, the clamping of the clamping mechanism 6 is cancelled, and under the limitation of the first limiting component 63 and the second limiting component 64, the airbag 61 does not contact the inner wall of the bobbin, and the weight of the yarn can be measured by the second metering mechanism 7 to cooperate with the first metering mechanism 5 to judge the weight of the wound yarn, so as to judge whether the yarn on the outer wall of the bobbin is obviously uneven in thickness. After the first metering mechanism 5 completes the measurement, the clamping mechanism 6 resumes the clamping to continue to transfer the bobbin of the wound yarn.

[0122] S3: When the bobbin of wound yarn is transported to the bobbin rack 3, the trigger mechanism 8 and the placement mechanism 4 cooperate to limit the bobbin of wound yarn, and restrict the bobbin from falling from the bobbin rack 3, so as to avoid the bobbin from falling due to rapid rotation in the subsequent weaving process, thereby improving the stability of subsequent weaving production.
