Description

Winding equipment of textile machinery

Technical Field

The invention relates to the technical field of winding equipment for forming and winding a plurality of yarns of textile machinery.

Background

The prior art CN101634065B related to the present invention has described a winding apparatus. This prior art discloses a specific structure of a winding plant comprising winding stations arranged horizontally side by side and vertically three-layer one above the other, each winding station being provided with a driving roller for driving the yarn around the winding tube and a yarn feed element for guiding the yarn into the winding station. A row of guide elements, not shown, is arranged below the winding position of the lowermost layer, said guide elements being arranged in the horizontal direction in correspondence with the position of the third delivery roller of the prior art.

The winding positions of a vertical column are aligned. The guide elements in the horizontal direction are arranged in an equidistantly spaced manner.

The yarn therefore inevitably needs to be deflected during its guidance from the guide element situated below to the feed element situated above, the deflection angle being the angle to the vertical. This deflection angle is an important factor in the formation of the yarn in the winding position. The difference in deflection angle results in different frictional forces and different yarn tensions experienced by the yarn as it passes over the element for the guide wire. The difference in the respective deflection angles from yarn to yarn will indirectly result in different forming parameters after the yarn has been formed for each winding position.

However, the desire for yarn formation is that the yarn formation parameters for each winding position need to be as consistent as possible. The prior art inconsistencies are particularly apparent when the number of winding positions in a vertical row is large, e.g., 4 or 5. Existing winding plant configurations do not meet this desire.

Disclosure of Invention

In order to meet the requirements, the invention provides the following technical scheme:

as a first technical solution of the invention, a winding device of a textile machine is provided with at least one winding group, wherein the winding group has a plurality of winding positions, each winding position is respectively provided with a driving roller and a wire feeding element, the wire feeding element is arranged corresponding to the middle part of the driving roller and is positioned on the upstream side of the driving roller, the winding positions are arranged in a manner of vertically stacking at least three layers and transversely side by side, the winding group is provided with a plurality of guide element groups which are transversely and horizontally arranged and used for guiding the yarns to the yarn feeding elements, the number of the guide elements of each guide element group is the same as that of the winding positions in a vertical row, in a vertical column of winding positions, projection points of the wire feeding elements of the winding positions in the vertical column on the connecting line of the guide elements are distributed between the guide elements at two ends of the plurality of guide elements in a fully or partially distributed manner.

The difference from the solutions described in the prior art is that the winding positions in a column are no longer all aligned with one another. The adjacent winding positions are staggered with each other. The staggered mode comprises that all winding positions of a vertical column are staggered or a part of the winding positions of the vertical column are staggered and a part of the winding positions of the vertical column are aligned. Compared with the prior art, the staggered arrangement enables the distance between the projection point of the wire feeding element of at least part of the winding position in a vertical column on the connecting line of the guide elements and the corresponding guide element to be reduced. The deflection angle of the thread section after the thread exits from the guide element to the thread feed element is correspondingly reduced. The technical result is that the deflection angles of all the threads are as uniform as possible while at least some of the thread deflection angles are reduced, so that the thread formation in all winding positions has as uniform parameters as possible.

As a second technical means of the present invention, a preferable spatial arrangement is that, in a vertical row of winding positions, the winding positions adjacent to each other vertically are offset from each other in the left-right direction.

As a preferable spatial arrangement, as a third aspect of the present invention, the winding positions of the winding groups are provided in a frame, wherein the transverse layers are stacked with being offset to a left end or a right end of the frame.

In a fourth aspect of the present invention, in a case where the winding apparatus is a four-layer winding apparatus, the winding positions are vertically arranged in a four-layer winding manner, and in the winding positions in one vertical row, a highest-layer winding position and a second-layer winding position higher than the lowest-layer winding position that are aligned are offset with respect to a third-layer winding position and a lowest-layer winding position that are aligned and are only lower than the highest-layer winding position, wherein, in one of the guide element groups, the two guide elements on the left side guide the yarn to the respective yarn feeding elements of the two winding positions offset to the left side in a non-interfering manner, and the two guide elements on the right side guide the yarn to the respective yarn feeding elements of the two winding positions offset to the right side in a non-interfering manner. Such an arrangement allows the winding device to achieve optimal results in terms of a balance between manufacturing costs and uniformity of deflection angle.

As a fifth aspect of the present invention, the winding station includes a traverse guide that guides the yarn in an axial direction of the driving roller of the winding station, and an area covered by the yarn movement locus between the yarn feeding element and the driving roller is an isosceles triangle. The yarn is driven to be guided back and forth along the axial direction of the driving roller after passing through the yarn feeding element.

As a sixth aspect of the present invention, the guide elements of one of the guide element groups corresponding to the one vertical winding position are provided at equal distances.

In order to further optimize the correspondence relationship between the guide elements and the yarn feeding elements, according to a seventh technical solution of the present invention, the guide elements at both ends in the guide element group guide the yarn to the yarn feeding element at the highest winding position and the yarn feeding element at the third winding position, respectively.

In order to reduce the influence of deflection angle on the formation of the yarns as much as possible, the deflection angle needs to be controlled within a certain value as much as possible, and as an eighth technical solution of the present invention, the deflection angle generated from the guide element through which each yarn passes to the corresponding yarn feeding element is less than 10 °.

Detailed Description

A winding device of a textile machine is a device formed by a winding group alone or by a plurality of winding groups arranged side by side and assembled together. Each winding group is further formed by regularly combining a plurality of winding positions and is used for forming and winding a plurality of yarns. Before entering the winding device, the yarn is subjected to the necessary yarn treatments, such as heating, cooling, drawing, etc., via the respective processing stations. The arrangement of the processing stations is different according to different types of machines.

The configuration of the winding station is shown in fig. 1. Fig. 1 is a schematic top view of the winding station. The drive roller 5 is shown in dashed lines below the bobbin 4, in a top view. The bobbin 4 is pressed against the drive roller 5 in parallel with the drive roller 5 and can be brought into contact with or moved away from the drive roller 5 by the cradle 3.

The winding station also has a thread feed element 9 for guiding the thread 8 into the winding station. The thread feeding member 9 is installed corresponding to the middle of the driving roller 5. After passing through the thread feed element 9, the thread 8 is finally wound onto the bobbin 4 after traversing the thread guide 6. The traverse guide 6 reciprocates in the axial direction of the drive roller 5 by a traverse mechanism not shown. Under the co-constraint of the fixed thread feeding element 9 and the moving traverse thread guide 6, the area covered by the motion track of the yarn 8 between the two is an isosceles triangle 7.

The configuration of one of the winding groups will be described below. Fig. 2 is a schematic view of the winding apparatus having one winding group. If the viewing angle of fig. 1 is defined as a vertical viewing angle, the viewing angle of fig. 2 corresponds to a horizontal viewing angle. The winding group comprises 16 winding positions 2.1-2.16, the winding positions are arranged in a vertically upper-lower four-layer stacked mode, and four adjacent winding positions in one layer are arranged in a side-by-side spaced mode at equal intervals. Each of the winding positions has the same structure as embodied in fig. 1. The number of winding bits and the number of layers are shown for illustrative purposes only, and may be 12 or three layers.

The winding positions 2.1-2.16 are accommodated in the frame 1. The winding groups have four transversely horizontally arranged guide element groups, each of which comprises four guide elements, a total of 16 guide elements 10.1-10.16, the numbers here also being schematic, and the distances between adjacent guide elements in each of the guide element groups being identical. The reason for providing the number of guide elements of each guide element group with four in this embodiment is that the guide elements of the guide element group correspond one-to-one to a vertical row of the thread feed elements, for example, a thread is guided from one of the four guide elements 10.1 to 10.4 to one of the four thread feed elements 9.1 to 9.4. The basic principle that this guidance needs to follow is to ensure that there is no interference between the yarns.

After being processed in the processing position before the winding device, one yarn enters one of the guide elements 10.1-10.4, is guided to one of the yarn feeding elements 9.1-9.4 towards the upper part, and finally enters the yarn winding and forming step to form a bobbin.

To better illustrate the salient features of the present invention, the winding positions 2.1, 2.5, 2.9, 2.13 in a vertical column are taken as examples, wherein the four layers are defined as the highest layer, the third layer, the second layer and the lowest layer from top to bottom. The four winding positions 2.1, 2.5, 2.9, 2.13 of the column are arranged in a regularly curved manner with respect to the vertical direction. Specifically, the adjacent winding bits 2.1 located in the highest layer and 2.5 located in the third layer are offset to the left and right from each other. The adjacent winding positions 2.5 on the third layer and 2.9 on the second layer are offset to the left and right. The adjacent winding positions 2.9 on the second layer and 2.13 on the bottommost layer are offset from left to right. Additionally, the winding positions 2.1 of the highest layer are aligned with the winding positions 2.9 of the second layer and the winding positions 2.5 of the third layer are aligned with the winding positions 2.13 of the lowest layer, so that the offset of adjacent winding positions in a column is the same, which is advantageous for the design, manufacturing and installation phases.

Further, the spindle position distance between each adjacent winding position in one layer is uniform, and the spindle position distances in different layers are also uniform. 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 lowest layer are biased towards the right end of the frame 1. Similarly, the offset between each adjacent layer is the same.

A yarn is guided from one of the guide elements to one of the feed elements in corresponding relationship thereto. The correspondence is set as follows: taking the winding positions 2.1, 2.5, 2.9, 2.13 of a column as an example, in the group of guide elements 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 threads to the thread feed elements 9.1, 9.3 of the winding positions 2.1, 2.9 of the column that are offset to the left. The two right-hand guide elements 10.3, 10.4 guide the respective thread to the thread feed elements 9.2, 9.4 of the winding positions 2.5, 2.13 offset to the right in the vertical row of winding positions. In particular, the guide elements 10.1, 10.4 at the two ends of the guide element group guide the thread to the thread feed element 9.1 of the highest winding position 2.1 and to the thread feed element 9.2 of the third winding position 2.5, respectively. The reason for this design of the yarn concept is explained below in connection with fig. 3 and 4.

FIG. 3 is a schematic diagram showing the position relationship of the projected points of a vertical line of wire feeding elements on the connecting line of the guide elements in the prior art; fig. 4 schematically shows the position relationship of the projected points of the wire feeding elements in the next vertical column on the connecting line of the guide elements in the embodiment of fig. 2. The thread is deflected when guided from the guide element 10.1 to the respective thread feed element 9.1, the deflection angle a in fig. 3 being the angle to the vertical after the thread deflection. The deflection angle a is a factor which influences the friction and the tension to which the yarn is subjected when it passes over the thread-guiding element, which ultimately influences the formation of the bobbin. In order to produce bobbins which are as uniform as possible, it is necessary to reduce as far as possible the differences in the friction and the tension to which the yarn is subjected as it passes over the thread-guiding element. To achieve the above object, it is necessary to reduce the value of the deflection angle a as much as possible and to make the difference between the deflection angles a as small as possible.

As can be seen from fig. 3, the thread feed elements 9.1, 9.2, 9.3, 9.4 in a column of the prior art are aligned with one another. Reference numeral 11 is a line passing through the guide member. 10.1 ', 10.2', 10.3 ', 10.4' on the connecting line 11 indicate the position of the guide elements 10.1, 10.2, 10.3, 10.4, respectively, on the connecting line 11. Reference numeral 9' denotes the coincident projected points of the aligned thread feed elements 9.1, 9.2, 9.3, 9.4 on the connecting line 11. The size of the above-mentioned deflection angle a is therefore determined by the distance from 10.1 ' to 9 ' and the distance from 9 ' to the thread feed element 9.1. The distance between the 9 'and the 10.2' is a, the distance between the 9 'and the 10.3' is b, the distance between the 9 'and the 10.4' is c, and the distance between the 9 'and the 10.1' is d. It can be seen that a, b, c, d differ significantly from each other.

In direct contrast to fig. 3 is fig. 4. Fig. 4 shows the relationship of the respective proxels corresponding to the embodiment in fig. 2. As shown in fig. 4, the thread feeding element 9.1 of the highest layer is aligned with the thread feeding element 9.3 of the second layer, and the projected points of the two projected on the connecting line 11 are coincident and are denoted by 12. The thread-feeding element 9.2 of the third layer is aligned with the thread-feeding element 9.4 of the lowermost layer, the projected points of which projected on said connecting line 11 coincide and are designated 13. The wire feeding element 9.1 of the highest layer is offset left and right relative to the wire feeding element 9.2 of the third layer, and the wire feeding element 9.3 of the second layer is offset left and right relative to the wire feeding element 9.4 of the lowest layer. The distance between the 12 and the 10.2 'is e, the distance between the 13 and the 10.3' is f, the distance between the 13 and the 10.4 'is g, and the distance between the 12 and the 10.1' is h.

In the exemplary embodiments of fig. 3 and 4, the distance between the respective thread feed element 9.1, 9.2, 9.3, 9.4 and its respective projection point on the connecting line 11 is constant. Therefore, the deflection angle a is smaller as the guide element is shorter from the projection point of its corresponding thread feed element on the connecting line 11.

As can be seen from a comparison of fig. 3, which shows the features of the prior art, and fig. 4, which shows the features of the present invention, the arrangement of the winding apparatus according to the present invention is such that the difference in value between e, f, g, h is reduced with respect to the difference in value between the distances a, b, c, d, and h is reduced with respect to d and e is reduced with respect to c. The technical result is that the deflection angle of each thread in the winding position of a column is as uniform as possible and the originally large deflection angle is reduced.

Fig. 5 is a schematic structural view of another embodiment of the winding apparatus having one winding group according to the present invention. The difference between the embodiment of fig. 4 and that of fig. 5 is that the four thread-feeding elements 9.1-9.4 of the winding position in a column are arranged in a curved manner without any alignment, so that their projected points on the connecting line 11 of the guide elements 10.1-10.4 do not coincide.

Fig. 6 schematically shows the position relationship of a vertical column of the projection points of the wire feeding element on the connecting line of the guide element in the embodiment of fig. 5. The projection point of the wire feeding element 9.1 on the connecting line 11 is marked by 9.1 ', the projection point of the wire feeding element 9.2 on the connecting line 11 is marked by 9.2', the projection point of the wire feeding element 9.3 on the connecting line 11 is 9.3 ', and the projection point of the wire feeding element 9.4 on the connecting line 11 is 9.4'. The distance between the 9.3 'and the 10.2' is i, the distance between the 9.4 'and the 10.3' is j, the distance between the 9.2 'and the 10.4' is k, and the distance between the 9.1 'and the 10.1' is l. As can be seen in comparison with the embodiment of fig. 4, the difference in the values of the distances i, j, k, l is further reduced with respect to the difference in the values of the distances e, f, g, h, so that the difference between the deflection angles a of the different yarns in this embodiment is further reduced.

The salient features of the present invention are shown in fig. 2, 4 and 5, 6, respectively. The embodiments of fig. 2 and 4 show that in a vertical row of winding positions, the thread feeding elements of each winding position in the vertical row are partially distributed between two end guide elements in the plurality of guide elements in a scattered manner on the guide element connecting line. The embodiments of fig. 5 and 6 show that, in a vertical row of winding positions, the projection points of the thread feeding elements of each winding position in the vertical row on the connecting line of the guide elements are all distributed between two end guide elements in the plurality of guide elements in a dispersed manner. In this way, the forming bobbins in each winding station have more consistent parameters with respect to the prior art.

The number of winding groups is only for illustrative purposes and may be ten or twelve winding groups, depending on the textile machine specifications. In order to reduce as much as possible the effect of the deflection angle on the yarn formation, the deflection angle a should be controlled to a value as much as possible, preferably less than 10 °.
