TECHNICAL FIELD

[0001] The present application relates to the technical field of spandex production, and particularly relates to a device and method for measuring the spandex content in spandex-covered yarn. BACKGROUND

[0002] With the continuous improvement of people's living standards, people begin to pursue a healthier and happier lifestyle, and people's demand for personalized clothing is also rapidly developing, and high-proportion spandex fabrics are on the rise. Spandex is prepared by polymerization of dihydric alcohol and diisocyanate, and is a high-elasticity fiber. According to the difference of dihydric alcohol, spandex can be divided into polyester spandex and polyether spandex. Spandex is widely used in various textile products, which can improve the elasticity of textiles and is beneficial to the development of elastic textiles. For example, after spandex-covered yarn is made by using spandex as core yarn of various fiber core-spun yarn, the spandex-covered yarn is woven into elastic fabric. Based on the spandex elastic yarn, good hand feeling and appearance can be obtained, and the elasticity of the fabric can be adjusted by mixing the proportion of spandex filaments, and it is easy to spin 25-2500 denier filaments of different thicknesses to meet the product demand of different purposes.

The detection process has low automation degree, and basically depends on the technology and experience of the operator. The cost of training operators is high. The stripping force and method of different personnel are different, the stripping efficiency is low, the result fluctuates greatly, and the standardization detection requirement cannot be met.

[0042] The sampling mechanism 3 is used to measure a fixed length of spandex yarn 1; the peeling mechanism 4 is set on the sampling mechanism 3 and used to peel the spandex yarn 11 and fiber yarn 12 in the sample of spandex yarn 1; the detection mechanism 5 is set outside the peeling mechanism 4 and used to detect the content of spandex yarn 11 in the sample of spandex yarn 1; the collection mechanism 6 is set outside the detection mechanism 5 and used to collect spandex yarn 11 and fiber yarn 12; and the conveying mechanism 7 is set outside the sampling mechanism 3 and used to position and convey the take-up roller 2 of the spandex yarn 1.

[0043] The peeling mechanism 4 includes two first clamping assemblies 41 respectively movably arranged at the upper and lower ends of the sampling mechanism 3 and used for clamping the two ends of the ammonia package yarn 1 to move close to each other until a plurality of network points 13 are formed on the ammonia package yarn 1, a second clamping assembly 42 movably arranged between the two first clamping assemblies 41 and used for positioning and clamping adjacent two network points 13, a peeling assembly 43 arranged on the second clamping assembly 42 and used for peeling the spandex yarn 11 and the fiber yarn 12 between the two network points 13, and a coiling assembly 44 arranged on the sampling mechanism 3 and used for coiling the peeled spandex yarn 11 and fiber yarn 12.

[0044] In the embodiment, the winding roller 2 with the ammonia package yarn 1 is conveyed by the conveying mechanism 7, and the sampling, peeling, detecting and collecting processes are integrated by cooperating with the sampling mechanism 3, the peeling mechanism 4, the detecting mechanism 5 and the collecting mechanism 6, so that the automation degree is high, the standardized detection is realized, the production line real-time monitoring is suitable, the sample collection is convenient for subsequent re-inspection or sampling inspection, the equipment does not need to be replaced or the sample does not need to be manually transferred, the personnel training cost is reduced, the detection efficiency is improved, in the sampling and peeling process, the sampling mechanism 3 quantitatively cuts the ammonia package yarn 1 with a fixed length, the weight error caused by the inconsistent sample length is eliminated, after the first clamping assembly 41 clamps the ammonia package yarn 1 upward and downward to form controllable network points 13, the second clamping assembly 42 accurately positions adjacent network points 13, the peeling assembly 43 operates in a fixed interval to avoid excessive pulling or omission, and the physical separation starting point of the spandex yarn 11 and the fiber yarn 12 is consistent, after the spandex yarn 11 and the fiber yarn 12 are coiled by the coiling assembly 44, the detection accuracy of the detecting mechanism 5 is improved, and the whole process is replaced by manual operation through mechanical clamping, positioning, peeling and coiling of the coiling assembly 44, so that the problems of uneven peeling force, residual fiber or spandex breakage caused by personnel technical differences are avoided, and the result accuracy is improved.

[0045] In detail, first, the conveying mechanism 7 cooperates with the sampling mechanism 3 to take a fixed length of the ammonia package yarn 1 from the winding roller 2; then, after the two first clamping mechanisms clamp the two ends of the ammonia package yarn 1 sample to move to form a plurality of network points 13, the second clamping assembly 42 clamps adjacent two network points 13, and then cooperates with the peeling assembly 43 to position and peel the spandex yarn 11 and the fiber yarn 12 between the two network points 13; then, after the second clamping assembly 42 cooperates with the peeling assembly 43 to completely separate the spandex yarn 11 and the fiber yarn 12, the coiling assembly 44 coils the spandex yarn 11 and the fiber yarn 12 and sequentially conveys them to the detecting mechanism 5 for detection; finally, after the collecting mechanism 6 collects the detected spandex yarn 11 and fiber yarn 12 into the corresponding winding roller 2, the conveying mechanism 7 divides and outputs the qualified and unqualified winding rollers 2.

[0046] It should be noted that the detection mechanism 5 uses an electronic scale with a unit of grams and an accuracy of four decimal places for weighing, and the data after weighing is collected and calculated in time by a computer, and then the content of spandex in the ammonia package silk 1 is quickly obtained; therefore, the detection mechanism 5 itself and the installation mode are prior art, and will not be described in detail here.

[0047] Further, as shown in Figure 4 the first clamping assembly 41 includes a first mounting seat 411 movably arranged on the sampling mechanism 3, two first clamping arms 412 arranged on the first mounting seat 411 in an open and close manner, and a camera 413 arranged on the sampling mechanism 3 and used for collecting the state image of the ammonia package silk 1.

[0048] In this embodiment, by setting the movement of the first mounting seat 411 and cooperating with the first clamping, different diameters of ammonia package silk 1 can be clamped, the height is adjusted to avoid excessive stretching or relaxation of yarn of different diameters of ammonia package, and the camera 413 is used to collect the state image of the ammonia package silk 1 forming the network point 13, so that the ammonia package silk 1 is in the same state before each peeling, the uniformity of the fiber silk 12 wrapping the spandex silk 11 is detected, and the detection error caused by the difference in tightness of the yarn is reduced.

[0049] It should be noted that the camera 413 itself and the installation mode are prior art, and will not be described in detail here.

[0050] Further, as shown in Figure 4 the second clamping assembly 42 includes a second mounting seat 421 movably arranged on the sampling mechanism 3 and used for mounting the camera 413, two second clamping arms 422 arranged on the upper and lower ends of the second mounting seat 421 in an open and close manner, and two third clamping arms 423.

[0051] In this embodiment, by setting the movement of the second mounting seat 421 to drive the camera 413 to move, the state image of the whole ammonia package silk 1 is collected, the accuracy of collection and detection is improved, and the state of the yarn between adjacent network points 13 is captured in real time, so that the second clamping arms 422 and the third clamping arms 423 are accurately clamped on the adjacent two network points 13 respectively, and the peeling interval is positioned.

[0052] When in use, during the process of moving the two first mounting seats 411 close to each other to make the ammonia package yarn 1 clamped on the first clamping arm 412 form the network point 13, the second mounting seat 421 reciprocates between the two first mounting seats 411, the camera 413 collects real-time state images of the whole ammonia package yarn 1 until the ammonia package yarn 1 forms a preset state, then the two first mounting seats 411 stop moving, and then the camera 413 moves with the second mounting seat 421 until it captures and positions the adjacent two network points 13, then the second mounting seat 421 stops moving to position the second clamping arm 422 and the third clamping arm 423 between the adjacent two network points 13, and the second clamping arm 422 and the third clamping arm 423 are closed to position and clamp the adjacent two network points 13 to position the stripping interval.

[0053] It should be noted that the camera 413 compares the image information in the computer to determine the formation state of the network point and the position of the network point, to ensure the accuracy of clamping and improve the accuracy of detection.

[0054] Further, as shown in Figures 4-7 The stripping assembly 43 includes a pressing needle 431 movably arranged on the second mounting seat 421 and cooperating with the spandex yarn 11 to press the spandex yarn 11 and the fiber yarn 12 apart, a picking needle 432 movably arranged on the second mounting seat 421 and used to pick out the separated spandex yarn 11, and a hook needle 433 movably and rotatably arranged on the sampling mechanism 3, and after the hook needle 433 hooks the middle part of the picked out spandex yarn 11, the hook needle 433 is rotated to make the two ends of the spandex yarn 11 entangled, and then the hook needle 433 hooks out the two ends of the spandex yarn 11 at the same time.

[0055] In this embodiment, by arranging the pressing needle 431, the picking needle 432 and the hook needle 433 to cooperate in sequence, the process from the initial separation of the spandex yarn 11 and the fiber yarn 12 to the accurate picking out of the spandex yarn 11 and the complete construction of the spandex yarn 11 is realized, the stripping process is accurate and reasonable, more reliable than traditional manual stripping, reduces fiber residue and improves stripping efficiency.

[0056] In detail, during use, firstly, the pressure needle 431 moves and presses down vertically on the spandex yarn 1, then moves the pressure needle 431 to the side of the spandex yarn 1 until the camera 413 captures the spandex yarn 11 disengaging from the pressure needle 431 and springing back to separate from the fiber filament 12. The pressure needle 431 then stops. Next, the picking needle 432 is moved and inserted between the spandex yarn 11 and the fiber filament 12 from the side of the spandex yarn 1. Then, the second clamping arm 422 or the third clamping arm 423 opens, and the picking needle 432 moves vertically away from the fiber filament 12 to pick out the spandex yarn 11. Finally, the hook needle 433 is moved to hook out the picked-out spandex yarn 1. When the peeling component 43 peels the two ends of the spandex yarn 1, the second clamping component 4... 2. After clamping two adjacent network points 13, the peeling section is located. At this time, when the picking needle 432 moves to pick out the spandex yarn 1, the first clamping component 41 needs to be opened until the hook needle 433 hooks out the spandex yarn 1 and separates it from the fiber yarn 12. Then, the first clamping component 41 clamps the fiber yarn 12 again. After the two ends of the spandex yarn 1 have been peeled out by the peeling component 43 multiple times, the friction between the spandex yarn 11 and the fiber yarn 12 can be greatly reduced. The peeling component 43 can directly peel out the middle of the spandex yarn 1. At this time, while the hook needle 433 hooks out the spandex yarn 1, the hook needle 433 is rotated to wrap the two ends of the spandex yarn 11, so that the two ends of the spandex yarn 11 can be hooked out at the same time.

[0057] It should be noted that the number of peeling components 43 is preferably two. The two peeling components 43 simultaneously separate the spandex filament 11 from the fiber filament 12 from both ends of the spandex filament 11, thereby improving the separation efficiency.

[0058] Furthermore, such as Figures 4-10 As shown, the coiled yarn assembly 44 includes a first support rod 441 rotatably mounted on the sampling mechanism 3, two first coiled yarn rods 442 rotatably mounted on the first support rod 441 and respectively located on both sides of the fiber filament 12, a first push plate 443 movably mounted on the first coiled yarn rod 442, a second support rod 444 rotatably mounted on the sampling mechanism 3, two second coiled yarn rods 445 that are open and rotatably mounted on the second support rod 444 and respectively located on both sides of the wound spandex filament 11, a clamping rod 446 movably mounted between the two second coiled yarn rods 445 and cooperating with the second coiled yarn rods 445 to clamp the spandex filament 11, and a second push plate 447 movably mounted on the second coiled yarn rods 445.

[0059] In this embodiment, by setting the first support rod 441 to cooperate with the rotation of the first coiled wire rod 442 and the movement of the first push plate 443, the fiber filament 12 held by the first clamping assembly 41 is wound up and then pushed out. By setting the second support rod 444 to cooperate with the movement and rotation of the second coiled wire rod 445, the opening and closing of the clamping rod 446 and the movement of the second push plate 447, the spandex filament 11 hooked by the hook 433 is wound up and then pushed out.

[0060] In detail, in use, after the second disc lead screw 445 moves to the two sides of the spandex filament 11 on the hook needle 433, the clamping rod 446 clamps the end of the spandex filament 11 away from the hook needle 433 with one second disc lead screw 445; then the spandex filament 11 is wound after rotating the second disc lead screw 445, the hook needle 433 or the second support rod 444 is rotated to make the end of the spandex filament 11 close to the hook needle 433 enter between the two second disc lead screws 445, and then the two second disc lead screws 445 are closed to clamp the spandex filament 11; then the second push plate 447 is moved to roll the wound spandex filament 11 outside the end of the spandex filament 11 close to the hook needle 433, the hook needle 433 is moved away from the spandex filament 11, and the push plate is moved to push out the spandex filament 11; finally, after the first disc lead screw 442 moves to the two sides of the fiber filament 12 on the first clamping assembly 41 or the second clamping assembly 42, the two first clamping assemblies 41 or the second clamping assemblies 42 are close to each other, and the first disc lead screw 442 is rotated to wind the fiber filament 12, and then the first clamping assembly 41 or the second clamping assembly 42 is opened to make the first push plate 443 push out the fiber filament 12.

[0061] Further, as shown in Figures 2-3 and Figures 11-12 , the sampling mechanism 3 includes a machine base 31, a straightening assembly 32 arranged on the machine base 31 and naturally straightening the spandex package 1 under gravity, two third mounting seats 33 respectively arranged at the upper and lower ends of the machine base, two groups of fourth clamping arms 34 respectively arranged at the upper and lower ends of the third mounting seat 33 and used for clamping the spandex package 1, and a cutter 35 arranged between the two groups of fourth clamping arms 34 and used for positioning and cutting the spandex package 1.

[0062] In this embodiment, by arranging the straightening assembly 32 under the action of gravity, it is ensured that the sampling section is in a naturally open state under a certain gravity, and the calculation deviation of the spandex content caused by excessive pre-stretching is avoided. The fourth clamping arms 34 on the two third mounting seats 33 fix the source end of the spandex package 1 and the end after being straightened by the straightening assembly 32, respectively, to form a standard detection section, and the two fourth clamping arms 34 clamp the two sides of the cutting position to avoid the contraction of the cut spandex package 1, facilitating subsequent sample detection, device resetting, and waste collection.

[0063] In detail, in use, taking one meter of the spandex package 1 measured on the machine base 31 as an example, the weight of the stretching assembly is 0.2 times the fineness of the spandex package 1, for example: fineness 175 dtex, the weight of the hanging weight is 175*0.2=35g, the corresponding weight of the stretching assembly is hung during measurement, until the spandex package 1 is straightened and opened under the action of gravity, the fourth clamping arm 34 is positioned and clamped, and the cutter 35 is positioned to cut one meter of the spandex package 1; repeat the above steps to take 3 or more samples for multiple detections, compare the detection results, and improve the accuracy of the detection.

[0064] It should be noted that the base 31 can be arranged on a vertical wall or a vertical fixed frame to realize vertical positioning and facilitate subsequent production detection.

[0065] Further, as shown in Figure 12 , the straightening assembly 32 includes a fourth mounting seat 321 movably arranged on the rack, a clamp 322 detachably arranged on the fourth mounting seat 321, a pushing arm 323 rotatably arranged on the fourth mounting seat 321 and used for pushing the clamp 322 to open, and a counterweight 324 detachably arranged on the clamp 322.

[0066] In this embodiment, by arranging the fourth mounting seat 321 to move and cooperate with the pushing arm 323 to push the clamp 322 to open, the clamping and separation between the clamp 322 and the ammonia-wrapped yarn 1 are realized. When the fourth mounting seat 321 is moved downward to pull the ammonia-wrapped yarn 1 clamped by the clamp 322 to a certain length, the clamp 322 is separated from the fourth mounting seat 321, and the counterweight 324 and the clamp 322 are pulled straight and open under the action of gravity.
