Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of a winding device of a textile machine for profile winding of a plurality of yarns. BACKGROUND

[0002] The prior art CN101634065B related to the present invention discloses a winding device. The prior art discloses the specific structure of the winding device, which comprises winding positions arranged in horizontal direction in parallel and in vertical direction in three layers. Each winding position is equipped with a driving roller for driving the yarn to wind on the winding tube and a yarn guiding element for guiding the yarn into the winding position. A row of unshown guiding elements is arranged below the winding positions in the bottom layer, and the guiding elements are arranged in the horizontal direction corresponding to the position of the third delivery roller of the prior art.

[0003] The winding positions in a vertical column are arranged in alignment. The guiding elements in the horizontal direction are arranged in an equal distance.

[0004] Therefore, the yarn inevitably needs to be deflected in the process of being guided from the guiding element below to the guiding element above, and the deflection angle is the angle with the vertical direction. The deflection angle is an important influencing factor of the profile of the yarn in the winding position. Different deflection angles will result in different friction forces and different yarn tensions when the yarn passes through the guiding element. The difference in the deflection angle of each yarn will indirectly result in different profile parameters of the yarn after the profile of the yarn in each winding position is formed.

[0005] However, the expectation of the yarn profile is that the profile parameters of the yarn in each winding position need to be as consistent as possible. Especially when the number of winding positions in a vertical column is large, such as 4 or 5, the inconsistency in the prior art is more obvious. The existing winding device structure cannot meet this expectation. SUMMARY

[0006] In order to meet the above-mentioned requirements, the present invention proposes the following technical solutions:

[0007] As a first technical solution of the present application, a winding device of a textile machine has at least one winding group, wherein the winding group has a plurality of winding positions, each of which is respectively provided with a driving roller and a yarn feeding element, the yarn feeding element is arranged corresponding to the middle part of the driving roller and located on the upstream side of the driving roller, the winding positions are arranged in a vertical at least three layers of stacking, horizontal side by side manner, the winding group has a plurality of horizontal arrangement of guiding element groups for guiding the yarn to the yarn feeding element, the number of guiding elements of each guiding element group is the same as the number of a vertical column of winding positions, in a vertical column of winding positions, the projection points of the yarn feeding elements of each winding position in the vertical column on the connecting line of the guiding elements are all distributed between the two end guiding elements of the plurality of guiding elements.

[0008] The difference from the technical solution in the prior art is that the winding positions in a vertical column are no longer all arranged in alignment with each other. The adjacent winding positions are arranged staggered with each other. The staggered manner includes that all the winding positions in a vertical column are staggered, or a part of the winding positions in a vertical column are staggered and a part are arranged in alignment. Compared with the prior art, the staggered arrangement makes the distance between the projection points of the yarn feeding elements of at least part of the winding positions in a vertical column on the connecting line of the guiding elements and the corresponding guiding elements be reduced. Therefore, the deflection angle of the yarn from the guiding elements to the yarn feeding elements is also correspondingly reduced. The technical effect brought about is that while the deflection angle of at least part of the yarn is reduced, the deflection angles of all the yarns are made as consistent as possible, and therefore, the yarn shaping of all the winding positions has parameters as consistent as possible.

[0009] As a more optimal spatial arrangement scheme, as a second technical solution of the present application, in a vertical column of winding positions, the upper and lower adjacent winding positions are arranged in a left-right offset manner.

[0010] As a more optimal spatial arrangement scheme, as a third technical solution of the present application, the winding positions of the winding group are arranged in a frame, wherein the horizontal layers are stacked in a left or right offset manner to the left or right end of the frame.

[0011] In the case of four-layer stacking of the winding device, as the fourth technical solution of the present application, the winding positions are arranged in vertical four-layer stacking, in a vertical column of the winding positions, the highest layer winding position aligned with the second layer winding position higher than the bottom layer winding position is offset relative to the third layer winding position only lower than the highest layer winding position and the bottom layer winding position aligned, wherein in one group of the guide elements, the two guide elements on the left side guide the yarns to the respective yarn feeding elements of the two winding positions offset to the left in a non-interfering manner, and the two guide elements on the right side guide the yarns to the respective yarn feeding elements of the two winding positions offset to the right in a non-interfering manner. Such an arrangement can balance the winding device between manufacturing cost and deflection angle consistency to obtain the best results.

[0012] As the fifth technical solution of the present application, the winding position comprises a traverse guide, which guides the yarn along the axial direction of the driving roller of the winding position, wherein between the yarn feeding element and the driving roller, the area covered by the yarn movement track is an isosceles triangle. The yarn is guided back and forth along the axial direction of the driving roller after passing through the yarn feeding element.

[0013] As the sixth technical solution of the present application, the guide elements of one group of guide elements corresponding to a vertical column of winding positions are arranged at equal distances.

[0014] To further optimize the correspondence between the guide elements and the yarn feeding elements, as the seventh technical solution of the present application, the guide elements at both ends of the group of guide elements guide the yarns to the yarn feeding elements of the highest layer winding position and the third layer winding position, respectively.

[0015] To minimize the influence of the deflection angle on yarn shaping as much as possible, the deflection angle needs to be controlled within a certain value as much as possible, as the eighth technical solution of the present application, the deflection angle generated by each yarn from the guide element it passes through to the corresponding yarn feeding element is less than 10°.

[0022] The winding device of the textile machine is a device formed by one winding group alone or a device formed by a plurality of winding groups arranged in parallel. Each winding group is further formed by a plurality of winding positions regularly combined to form a plurality of yarns. Before entering the winding device, the yarns need to pass through the corresponding processing positions for necessary yarn processing, such as heating, cooling, stretching, etc. The arrangement of the processing positions is different according to the type of the machine.

[0023] The configuration of the winding position is shown in Figure 1 . Figure 1 is a top view schematic diagram of the winding position. Due to the angle of view, the drive roller 5 located below the bobbin 4 is represented by a dashed line. The bobbin 4 is pressed on the drive roller 5 in a parallel manner and can be in contact with or away from the drive roller 5 under the action of the cradle 3.

[0024] The winding position also has a thread-in element 9 for guiding the yarn 8 into the winding position. The thread-in element 9 is installed corresponding to the middle part of the drive roller 5. After passing through the thread-in element 9, the yarn 8 passes through the traversing guide 6 and is finally wound on the bobbin 4. The traversing guide 6 reciprocates along the axial direction of the drive roller 5 under the drive of the traversing mechanism not shown. Under the joint constraint of the fixed thread-in element 9 and the moving traversing guide 6, the movement track of the yarn 8 between them covers an isosceles triangle 7.

[0025] The configuration of one winding group will be introduced below. Figure 2 is a structural schematic diagram of the winding device with one winding group. If the angle of view of Figure 1 is defined as a vertical angle of view, then the angle of view of Figure 2 corresponds to a horizontal angle of view. The one winding group includes 16 winding positions 2.1-2.16 arranged in four layers vertically stacked, and four adjacent winding positions in one layer are arranged equidistantly side by side. Each winding position has the same projection point on the connecting line of the guide elements. Figure 1The structure is shown in the figure. The number of winding positions and the number of layers are only for illustrative purposes, and can also be 12 or three layers.

[0026] The winding positions 2.1-2.16 are accommodated in the frame 1. The winding group has four groups of transversely horizontally arranged guide elements, each of which includes four guide elements, a total of 16 guide elements 10.1-10.16, the numbers here are also illustrative, and the distance between adjacent guide elements in each group of guide elements is the same. In this embodiment, the reason for setting the number of guide elements in each group of guide elements to four is that the guide elements in the group of guide elements correspond one-to-one to a vertical column of the yarn feeding elements, for example, the yarn is guided from one of the four guide elements 10.1-10.4 to one of the four yarn feeding elements 9.1-9.4. The basic principle that needs to be followed for such guidance is to ensure that there is no mutual interference between yarns.

[0027] A yarn after being processed at the processing position before the winding device enters one of the guide elements 10.1-10.4, is guided upwards to one of the yarn feeding elements 9.1-9.4, and finally enters the yarn winding forming step to form a bobbin.

[0028] In order to better illustrate the outstanding features of the present application, the winding positions 2.1, 2.5, 2.9, 2.13 located in a vertical column are taken as an example for illustration, wherein the four layers are defined from top to bottom as the highest layer, the third layer, the second layer, and the bottom layer. The four winding positions 2.1, 2.5, 2.9, 2.13 in the vertical column are regularly curvedly arranged relative to the vertical direction. Specifically, the adjacent winding position 2.1 located in the highest layer and the winding position 2.5 located in the third layer are left-right offset from each other. The adjacent winding position 2.5 located in the third layer and the winding position 2.9 located in the second layer are left-right offset from each other. The adjacent winding position 2.9 located in the second layer and the winding position 2.13 located in the bottom layer are left-right offset from each other. Additionally, the winding position 2.1 of the highest layer is aligned with the winding position 2.9 of the second layer, and the winding position 2.5 of the third layer is aligned with the winding position 2.13 of the bottom layer, so that the offset amount of each adjacent winding position in a vertical column is the same, which is advantageous for the design, manufacturing and installation stages.

[0029] Further, the distance between each adjacent winding position in the layer is consistent, and the distance between the winding positions in different layers is also consistent. In the frame 1 accommodating the winding positions, all the winding positions 2.1, 2.2, 2.3, 2.4 of the highest layer are biased towards the left end of the frame 1, all the winding positions 2.5, 2.6, 2.7, 2.8 of the third layer are biased towards the right end of the frame 1, all the winding positions 2.9, 2.10, 2.11, 2.12 of the second layer are biased towards the left end of the frame 1, and all the winding positions 2.13, 2.14, 2.15, 2.16 of the bottom layer are biased towards the right end of the frame 1. Also, the biasing amount between each adjacent layer is the same.

[0030] One yarn needs to be guided from one guide element to the corresponding yarn inlet element. The correspondence is set as follows: taking the column of winding positions 2.1, 2.5, 2.9, 2.13 as an example, in the guide element group comprising the guide elements 10.1, 10.2, 10.3, 10.4, the two guide elements 10.1, 10.2 on the left guide the respective yarns to the yarn inlet elements 9.1, 9.3 of the winding positions 2.1, 2.9 in the column of winding positions which are relatively offset to the left. The two guide elements 10.3, 10.4 on the right guide the respective yarns to the yarn inlet elements 9.2, 9.4 of the winding positions 2.5, 2.13 in the column of winding positions which are relatively offset to the right. In particular, the guide elements 10.1, 10.4 at the two ends of the guide element group guide the yarns to the yarn inlet elements 9.1 of the winding position 2.1 of the highest layer and the yarn inlet elements 9.2 of the winding position 2.5 of the third layer, respectively. The reasons for the design of the yarns will be described below in conjunction with Figure 3 and Figure 4 .

[0031] Figure 3 The position relationship of the projection points of a column of yarn inlet elements on the guide element connecting line in the prior art is schematically shown; Figure 4 The position relationship of the projection points of a column of yarn inlet elements on the guide element connecting line in the embodiment of Figure 2 is schematically shown. When the yarn is guided from the guide element 10.1 to the corresponding yarn inlet element 9.1, it will be deflected, Figure 3the deflection angle A in the yarn deflection is the angle between the deflected yarn and the vertical. The deflection angle A is a factor influencing the friction force experienced by the yarn when passing the guide element and the tension experienced by the yarn, which ultimately influences the formation of the package. In order to produce as consistent packages as possible, it is desirable to reduce the differences in the friction force experienced by the yarn when passing the guide element and the tension experienced by the yarn as much as possible. In order to achieve the above, it is desirable to reduce the values of the deflection angle A as much as possible and to have as little difference as possible between the deflection angles A.

[0032] from Figure 3 It can be seen that the guide elements 9.1, 9.2, 9.3, 9.4 in the column are aligned with each other. The reference 11 is the line connecting the guide elements. The 10.1', 10.2', 10.3', 10.4' on the line 11 indicate the positions of the guide elements 10.1, 10.2, 10.3, 10.4 on the line 11, respectively. The reference 9' is the projection point of the aligned guide elements 9.1, 9.2, 9.3, 9.4 on the line 11. Therefore, the size of the above-mentioned deflection angle A is determined by the distance from 10.1' to 9' and the distance from 9' to the guide element 9.1. The distance between 9' and 10.2' is a, the distance between 9' and 10.3' is b, the distance between 9' and 10.4' is c, and the distance between 9' and 10.1' is d. It can be seen that the differences between a, b, c, d are large.

[0033] In direct contrast to Figure 3 Figure 4 . Figure 4 The relationship between the projection points corresponding to the embodiments in Figure 2 is shown. As shown in Figure 4 , the guide element 9.1 of the highest layer is aligned with the guide element 9.3 of the second layer, and the projection points of the two on the line 11 coincide and are marked as 12. The guide element 9.2 of the third layer is aligned with the guide element 9.4 of the bottom layer, and the projection points of the two on the line 11 coincide and are marked as 13. The guide element 9.1 of the highest layer is offset to the left and right relative to the guide element 9.2 of the third layer, and the guide element 9.3 of the second layer is offset to the left and right relative to the guide element 9.4 of the bottom layer. The distance between 12 and 10.2' is e, the distance between 13 and 10.3' is f, the distance between 13 and 10.4' is g, and the distance between 12 and 10.1' is h.

[0034] In Figure 3 and Figure 4 ​In the respective embodiments, the distance between each of the thread feeding elements 9.1, 9.2, 9.3, 9.4 and its respective projection point on the line 11 is constant. Thus, the smaller the distance between the guide element and its corresponding projection point on the line 11, the smaller the deflection angle A.

[0035] Contrast to the embodiments embodying the features of the prior art Figure 3 and the embodiments embodying the features of the present application Figure 4 It can be seen that the arrangement of the winding device of the present application can reduce the numerical difference between the values of e, f, g, h relative to the numerical difference between the values of the distances a, b, c, d, and reduce the value of h relative to the value of d and reduce the value of e relative to the value of c. The technical effect achieved thereby is that the deflection angle of each yarn in a column of winding positions is as uniform as possible, and the originally larger deflection angle is reduced.

[0036] Figure 5 Structural schematic diagram of another embodiment of the winding device with one winding group of the present application. Figure 4 Contrast to the embodiments embodying the features of the prior art Figure 5 The difference between the embodiments is that the four thread feeding elements 9.1-9.4 of the winding positions in a column are arranged in a curved manner without any alignment, so that the projection points of the guide elements 10.1-10.4 on the line 11 do not coincide with each other.

[0037] Figure 6 Schematically show Figure 5 The position relationship of the projection points of the thread feeding elements in a column on the line of the guide elements in the embodiment. The projection point of the thread feeding element 9.1 on the line 11 is marked as 9.1', the projection point of the thread feeding element 9.2 on the line 11 is marked as 9.2', the projection point of the thread feeding element 9.3 on the line 11 is 9.3', and the projection point of the thread feeding element 9.4 on the line 11 is 9.4'. The distance between 9.3' and 10.2' is i, the distance between 9.4' and 10.3' is j, the distance between 9.2' and 10.4' is k, and the distance between 9.1' and 10.1' is l. Contrast to the embodiments in Figure 4 It can be seen that the numerical difference between the distances i, j, k, l is further reduced relative to the numerical difference between the distances e, f, g, h, so that the difference between the deflection angles A of different yarns in this embodiment is further reduced.

[0038] The outstanding features of the present application are embodied in Figure 2 , Figure 4 and Figure 5 , Figure 6 . Figure 2 andFigure 4 Embodiments of the application are such that in a vertical column of winding positions, the yarn entry elements of each of the winding positions in the vertical column are partially dispersedly distributed between the end guide elements of the plurality of guide elements on the guide element line. Figure 5 With Figure 6 Embodiments of the application are such that in a vertical column of winding positions, the projection points of the yarn entry elements of each of the winding positions in the vertical column are fully dispersedly distributed between the end guide elements of the plurality of guide elements on the guide element line. In this way, the forming cans in each winding position have more consistent parameters relative to the prior art.

[0039] The number of winding groups is only for illustrative purposes, and there can be ten or twelve winding groups according to different specifications of textile machinery. In order to minimize the influence of the deflection angle on yarn forming, the deflection angle A needs to be controlled within a certain value as much as possible, preferably less than 10°.
