[0034] The utility model will be described in detail below in combination with the specific implementation shown in the drawings. But these implementation does not limit the utility model, the conversion of structure, method or function made by the ordinary skill in the art according to these implementation is included in the protection scope of the utility model.

[0035] It should be understood that the terms such as "upper", "above", "lower", "below" used herein to indicate the spatial relative position are for the purpose of convenient description to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The spatial relative position terms can be intended to include different orientations of the device in use or work except the orientation shown in the drawing.

[0036] An embodiment of the utility model provides a kind of winding card device that can avoid winding to non-winding part, and the good product yarn card is wound.

[0037] A kind of winding card device 200 of this embodiment, the winding card device 200 is used to wind yarn 20 to card plate 10, card plate 10 is composed of winding part 11 and non-winding part 12, winding part 11 is the main winding area of yarn 20, and non-winding part 12 includes bevel 121 or flat section 122, and is not suitable for winding yarn 20.Yarn card 100 as Figure 1 shown, good winding should not appear in non-winding part 12.

[0038] As shown in Figures 3-5 , the yarn winding card device 200 comprises a winding mechanism 30 and a guide mechanism 40, the winding mechanism 30 drives the rotation of the card plate 10, the first rotation axis T1 of the card plate 10 extends along the first direction T0, the distance from the outer wall of the winding part 11 to the first rotation axis T1 is different from the distance from the outer wall of the non-winding part 12 to the first rotation axis T1. The outer wall of the winding part 11 is the position farthest from the first rotation axis T1 on the outer surface of the winding part 11, and the outer wall of the non-winding part 12 is similar to the outer wall of the winding part 11.

[0039] The winding mechanism 30 rotates the card plate 10 around the first rotation axis T1 to wind the yarn 20 on the surface of the card plate 10. In the design, the distance from the outer wall of the winding part 11 to the rotation axis is less than the distance from the outer wall of the non-winding part 12 to the rotation axis, which facilitates the identification of the relative positions of the winding part 11 and the non-winding part 12 by detecting the difference, and ensures that the yarn 20 is wound in the predetermined area.

[0040] Figure 1 In this embodiment, the winding part 11 comprises a starting end 111 and an ending end 112, the yarn 20 is wound between the starting end 111 and the ending end 112, the non-winding part 12 comprises an inclined angle 121 and a straight section 122, the inclined angle 121 is arranged between the winding part 11 and the straight section 122.

[0041] In order to clearly express the positions and directions described in this embodiment, in this embodiment, the starting end 111 is defined as being located on the right side and the ending end 112 is defined as being located on the left side.

[0042] The guide mechanism 40 comprises a guide seat 41, a yarn positioning part 42 and a translation driving part 43, the guide seat 41 is fixed opposite to the yarn positioning part 42, the yarn 20 is wound on the card plate 10 through the yarn positioning part 42, and the translation driving part 43 drives the guide seat 41 to move reciprocally parallel to the first rotation axis T1. The guide seat 41 is fixed to the yarn positioning part 42, the yarn 20 is wound on the surface of the winding part 11 of the card plate 10 after passing through the yarn positioning part 42, and the yarn positioning part 42 moves reciprocally in the direction of the first rotation axis T1, that is, moves along the left-right direction, so as to wind the yarn 20 on the winding part 11. The first rotation axis T1 is parallel to the left-right direction.

[0043] The yarn winding card device 200 further comprises a detection mechanism 50, as shown in Figure 4 、 6 , the detection mechanism 50 is fixed opposite to the guide seat 41, the detection mechanism 50 determines whether the yarn positioning part 42 is aligned with the winding part 11 or the non-winding part 12 according to the detected distance between the card plate 10, and the detection mechanism 50 judges whether the alignment position of the yarn 20 is correct by detecting the distance difference between the surfaces of the card plate 10.

[0044] During the movement of the guide 41 in the first direction T0, when the detection mechanism 50 determines that the yarn positioning portion 42 is aligned with the non-winding portion 12, the detection mechanism 50 sends a signal to trigger the reverse movement of the translation driving portion 43, and the translation driving portion 43 drives the guide 41 to move in the direction opposite to the first direction T0, so that the yarn 20 is timely adjusted to the range of the winding portion 11. That is, during the movement of the guide 41 from right to left, once the detection mechanism 50 detects the non-winding portion 12, the guide 41 is changed to move to the right.

[0045] In actual application, when the winding starts, the card 10 is driven by the winding mechanism 30 to rotate at a constant speed, and the yarn 20 is wound on the surface of the card 10 through the guide 41 and the yarn positioning portion 42. During the translation movement of the guide 41, the detection mechanism 50 detects the position of the yarn positioning portion 42 in real time. According to the change of the position distance, the detection mechanism 50 quickly judges and outputs a control signal to drive the guide 41 to quickly move reversely, so as to avoid the yarn 20 from being wound on the non-winding portion 12 (for example, the bevel 121), thereby forming a neat and beautiful winding form.

[0046] Therefore, the winding card device 200 of the embodiment solves the problem that the yarn 20 is wound on the non-winding portion 12 due to errors or inertia in the traditional winding card device 200, improves the winding precision, significantly improves the beauty of the distribution of the yarn 20, and improves the winding efficiency and the reliability of the equipment.

[0047] Further, as shown in Figure 4 , 5 , the winding mechanism 30 includes a base 32, a rotation driving portion, and a pair of clamps 31. The base 32 fixes the rotation driving portion, one of the pair of clamps 31 is connected to the output end of the rotation driving portion, and the other of the pair of clamps 31 is rotationally connected to the base 32. The card 10 is fixed between the pair of clamps 31.

[0048] The rotation driving portion is installed on the base 32, and the output end thereof is connected to one side of the clamp 31, and the other clamp 31 can rotate synchronously. The card 10 is fixed between the pair of clamps 31 and rotates around the first rotation axis T1 with the action of the rotation driving portion, thereby ensuring the stability of the card 10 during rotation. The rotation speed is accurately controlled by the rotation driving portion, and the translation movement of the guide mechanism 40 is matched, thereby realizing uniform winding. In addition, due to the high-precision matching between the clamp 31 and the card 10, the shaking of the card 10 during rotation is reduced, and the beauty of the winding and the operation reliability of the equipment are further improved.

[0049] In one of the embodiments of the embodiment, as shown in Figure 8 and 9As shown, the yarn winding card device 200 further comprises a positioning part 60, which comprises a transmitting end 62 located on one of the base 32 and the clamp head 31, and a receiving end 61 located on the other one; when the clamp head 31 is rotated to a preset position, the transmitting end 62 is aligned with the receiving end 61, at which time the posture of the card plate 10 is accurately determined. The detection mechanism 50 determines the alignment of the winding part 11 or the non-winding part 12 according to the posture of the card plate 10 when the transmitting end 62 is aligned with the receiving end 61. Thus, the problem of winding misalignment caused by initial installation deviation or rotation error of the clamp head 31 is effectively avoided, and the winding precision and the automation level of the device are further improved.

[0050] Further, as shown, when the clamp head 31 is rotated to the preset position, the card plate 10 is in a horizontal posture in the first horizontal plane, and the detection mechanism 50 detects the distance from the card plate 10 in the first horizontal plane. Figure 9

[0051] When the clamp head 31 is rotated to the preset position, the card plate 10 is in a horizontal posture, so that the detection mechanism 50 can accurately detect the distance between the card plate 10 and the yarn positioning part 42 in the horizontal plane. Through this design, the detection mechanism 50 can complete distance measurement in the same plane, and each time it ensures that the leftmost edge or the rightmost edge of the card plate 10 is detected, reducing the error introduced by the change of detection angle. In addition, the design of the horizontal posture facilitates the calculation of numerical values and the installation and debugging of the device. Figure 1

[0052] Further, the positioning part 60 is provided as a light emitting and receiving sensor, the transmitting end 62 emits a photoelectric signal, and the receiving end 61 receives the photoelectric signal. To determine the posture of the card plate 10 in the preset position. The use of the photoelectric sensor not only has high sensitivity and detection accuracy, but also has the characteristics of fast response and non-contact. At the same time, this sensor has strong adaptability to the external environment and can stably operate in a complex factory environment. Through the positioning of the light emitting and receiving photoelectric signal, the yarn winding card device 200 can quickly calibrate the initial position of the card plate 10, thereby further optimizing the operating efficiency of the device.

[0053] The clamp head 31 can be generally disc-shaped, and a hole is formed on the surface, the transmitting end 62 or the receiving end 61 is installed in the hole, and the other one of the transmitting end 62 or the receiving end 61 is fixed on the base 32 aligned with the hole in the horizontal position, so as to calibrate the position and posture through the photoelectric signal.

[0054] The cooperation of the winding mechanism 30 and the positioning part 60 not only improves the automation level and winding quality of the device, but also reduces the operation difficulty and maintenance cost of the device. These improvements enable the device to adapt to a wider range of yarn winding needs and exhibit significant effects in actual application.

[0055] ​​In another embodiment of this example, the positioning part 60 may not be provided. During the rotation of the board, the detected distance change roughly follows a sine curve trend. Based on the analysis of the extreme values ​​of this curve, it can also be determined whether the non-winding part 12 has been reached.

[0056] Furthermore, such as Figure 6 As shown, the yarn 20 emitted by the warp positioning part 42 and the detection direction of the detection mechanism 50 are located in the same plane perpendicular to the first rotation axis T1. When the clamping plate 10 rotates and the yarn guide seat 41 drives the yarn positioning part 42 to move left and right, the detection mechanism 50 can quickly determine whether the yarn 20 is aligned with the winding part 11. If it is detected that the yarn 20 is about to deviate from the winding part 11, it also means that the yarn positioning part 42 has deviated to the non-winding part 12. The system can adjust the translation drive part 43 in time to ensure that the yarn 20 is realigned, thereby significantly improving the system's response speed and adjustment capability during dynamic yarn winding. If the yarn 20 emitted by the warp positioning part 42 and the detection direction of the detection mechanism 50 are not in the same plane, it is necessary to calculate the offset. This embodiment reduces the waste of computation caused by the offset between the two.

[0057] The detection mechanism 50 determines whether the yarn positioning part 42 is aligned with the winding part 11 or the non-winding part 12 based on the detected distance between the yarn positioning part 42 and the card plate 10, including:

[0058] When the detection mechanism 50 aligns between the starting end 111 and the ending end 112, the distance detected by the detection mechanism 50 from the card plate 10 corresponds to the detection mechanism 50 aligning with the winding part 11; when the detection mechanism 50 detects a change in the distance from the ending end 112 to the oblique angle 121, the yarn positioning part 42 changes from aligning with the winding part 11 to aligning with the non-winding part 12.

[0059] When the system detects a gradual change in distance from the endpoint 112 to the oblique angle 121, it can identify that the yarn positioning part 42 has aligned from the winding part 11 to the non-winding part 12, and quickly reverses direction via the translation drive part 43 to realign the yarn 20 with the winding part 11. This distance-based detection and adjustment mechanism can accurately determine the winding position and effectively prevent the yarn 20 from getting tangled in the oblique angle 121 or other non-winding part 12 areas.

[0060] Furthermore, such as Figure 6As shown, the yarn positioning part 42 comprises a yarn guide wheel, which comprises a first tapered wall 421 and a second tapered wall 422 arranged in opposite directions, and a yarn guide groove 423 formed at the intersection of the first tapered wall 421 and the second tapered wall 422. The detection direction of the detection mechanism 50 is located on the plane of the yarn guide groove 423 perpendicular to the second rotation axis T2 of the yarn guide wheel. The yarn 20 is guided through the yarn guide groove 423, and the yarn 20 can be reliably restricted in the yarn guide groove 423, so that the yarn 20 is not easy to deviate even in the case of high-speed winding or unstable movement of the card 10. The detection direction of the detection mechanism 50 is located on the plane of the yarn guide groove 423, so that the detection mechanism 50 can accurately judge the guiding position of the yarn 20, and further improve the winding accuracy. Preferably, the second rotation axis T2 is parallel to the first rotation axis T1.

[0061] The detection mechanism 50 of the embodiment is a reflective optical fiber sensor. The optical fiber sensor judges the distance between the detection mechanism 50 and the card 10 by emitting an optical signal and receiving the optical signal reflected from the card 10. In the implementation process, this non-contact detection method can monitor the position of the yarn positioning part 42 in real time with high sensitivity. When the yarn positioning part 42 moves to the non-winding part 12, the reflective optical fiber sensor can quickly capture the change in distance and instruct the translation driving part 43 to adjust the position of the yarn guide seat 41, so that the yarn 20 quickly recovers to the winding part 11. The embodiment improves the detection accuracy and response speed, reduces the maintenance cost of the device, and significantly enhances the reliability and durability of the equipment.

[0062] Further, as shown in Figure 3 and 5 The winding card device 200 further comprises a tensioning mechanism 70, which outputs the yarn 20 in a tensioning state to the yarn positioning part 42. The tensioning mechanism 70 prevents the yarn 20 from relaxing or knotting during the winding process by applying a moderate tension to the yarn 20, thereby improving the quality of the winding. When the winding card device 200 operates at high speed, the presence of the tensioning mechanism 70 can effectively maintain the tightness of the yarn 20, so that the yarn 20 is more uniformly wound on the winding part 11 of the card 10, thereby improving the consistency and aesthetics of the finished product.

[0063] In addition, Figure 3 and 5 It is also shown that at least two groups of winding card devices 200 are fixed on the same rack 300, and the two groups of winding card devices 200 are arranged on the rack 300 to work.

[0064] The working process of the winding card device 200 will be described below:

[0065] The whole movement process of the winding card device 200 realizes the reciprocating movement of the guide seat 41 and its coordination with the detection mechanism 50, thereby avoiding winding of the yarn 20 to the non-winding part 12 (such as the bevel 121).

[0066] At the beginning of winding, the winding mechanism 30 drives the card 10 to rotate uniformly around the first rotation axis T1, and the guide seat 41 moves reciprocatingly along the left-right direction under the action of the translation driving part 43, and the yarn positioning part 42 uniformly winds the yarn 20 layer by layer on the winding part 11 area of the card 10. The movement of the guide seat 41 starts from the starting end 111 of the winding part 11 and gradually translates to the direction of the terminal end 112, while the rotation of the card 10 makes the yarn 20 cover the outer wall of the winding part 11. The detection mechanism 50 judges in real time whether the guide seat 41 is still located within the winding part 11 by detecting the distance from the surface of the card 10 through the detection mechanism 50 (such as a reflective optical fiber sensor), and continuously monitors the position of the yarn positioning part 42.

[0067] When the guide seat 41 continues to move and reaches the non-winding part 12 (such as the bevel 121), the distance change detected by the detection mechanism 50 appears obvious fluctuation. This fluctuation is due to the fact that the distance from the surface of the bevel 121 to the first rotation axis T1 is longer than the distance from the outer surface of the winding part 11 to the first rotation axis T1, and the detection mechanism 50 rapidly judges that the guide seat 41 is no longer aligned with the winding part 11 by using this distance change trend, and immediately sends a signal to the translation driving part 43.

[0068] After receiving the signal, the translation driving part 43 rapidly starts the reverse movement of the guide seat 41, so as to return it to the winding part 11 area, ensure that the yarn 20 exits from the non-winding part 12 area in time, and re-aligns with the winding part 11, thereby avoiding winding of the yarn 20 to the bevel 121 area, and forming neat and beautiful distribution of the yarn 20.

[0069] The detection mechanism 50 and the translation driving part 43 highly coordinate during the whole movement process. The detection mechanism 50 accurately captures the position change of the yarn positioning part 42 through real-time distance monitoring, and the translation driving part 43 realizes timely adjustment of the guide seat 41 through rapid response and accurate control. Finally, this movement process not only avoids winding of the yarn 20 to the non-winding part 12, but also significantly improves the winding accuracy and product beauty, thereby providing guarantee for efficient and high-quality winding.

[0070] Compared with the prior art, the embodiment has the following beneficial effects:

[0071] The yarn winding card device 200 is combined with the guide mechanism 40 by introducing the detection mechanism 50, effectively solves the problem that the yarn 20 is wound to the non-winding part 12 of the card plate 10, and significantly improves the appearance beauty and winding precision of the yarn card 100. Specifically, the detection mechanism 50 can accurately judge whether the yarn 20 reaches the non-winding part 12 by monitoring the distance between the yarn 20 and the card plate 10 in real time, if it reaches, the guide mechanism 40 can quickly move reversely through the translation driving part 43, timely correct the winding position of the yarn 20, and avoid the yarn 20 exceeding the winding part 11 range. The yarn winding card device 200 can improve the winding beauty while improving the production efficiency and product quality, and has good application prospect.
