Description

The technical field to which the present invention relates is a winding device of a textile machine for winding a wound body from a plurality of yarns.

Chinese Patent No. 101634065, one of the prior art related to the present invention, describes a winding device. The detailed structure of the winding device is disclosed in the prior art, which has winding positions that are horizontally arranged and vertically stacked. Each winding position comprises a drive roll for driving the winding tube on which the yarn is wound and a yarn entry element for guiding the yarn to the winding position. A row of guide elements, not shown, is positioned below the winding position of the lower layer. The guide element is arranged horizontally corresponding to the position of the third delivery roller.

The winding positions of one vertical line are aligned with each other. The horizontally arranged guide elements have equal distances from each other.

The yarn is therefore guided from the lower guide element to the higher yarn entry element so that the yarn is not deflected with a deflection angle formed with reference to the vertical direction. It is inevitable. The turning angle is an important factor affecting bobbin formation. Different deflection angles result in different frictional forces and different thread tensions applied to the thread as it passes through the thread guide. Variations in turning angles between yarns indirectly result in different wound body parameters after the bobbin is formed.

Nevertheless, the expectation for the bobbin is that the bobbin at each winding position has as uniform bobbin parameters as possible. Especially when a vertical line has a relatively large number of winding positions, for example 4 or 5 winding positions, the non-uniformity becomes more pronounced. Winding devices of existing construction cannot meet such expectations.

In order to meet the above requirements, the present invention proposes the following technical schemes.

According to a first technical scheme of the present invention, a winding device of a textile machine has at least one winding group, said winding group comprising a plurality of winding positions, these windings Each of the positions is provided with a respective drive roll and yarn entry element, the yarn entry element being positioned upstream of the drive roll and positioned to correspond to the central section of the drive roll. , the winding positions are arranged in the form of at least three vertically stacked layers, located laterally, and on the lower side of the winding group, the yarn entry element of the winding position A plurality of horizontally and laterally arranged guide elements are provided for guiding the thread, the guide elements being divided into a plurality of guide element groups, the guide elements in each said guide element group is equal to the number of winding positions in one vertical line, and in one vertical line of winding positions each said The projected points of the yarn entry elements at the winding position are all dispersedly distributed between the leftmost guide element and the rightmost guide element of the guide element group, or are distributed so as to partially overlap. there is

Unlike the technical schemes in the prior art, not all winding positions of one vertical line are aligned. Adjacent winding positions are staggered. Alternating morphology includes two possibilities. One possibility is that all winding positions of one vertical line are staggered. The other possibility is that the winding positions of part of one vertical line are staggered and the winding positions of part of one vertical line are aligned. The proposed staggered arrangement makes it possible to reduce the distance from the point of projection of at least some thread entry elements onto the connecting line to the corresponding guide elements. Accordingly, the deflection angle of the thread as it proceeds from the guide element to the thread entry element is correspondingly reduced. The technical effect provided by the technical scheme is that while at least some threads have their deflection angles reduced, the deflection angles of all threads can be made as uniform as possible, thereby , the bobbin body in all winding positions can have parameters that are as uniform as possible.

As a technical scheme for optimizing space utilization, the second technical scheme of the present invention is that the winding positions are offset to the right or left on top of each other in one vertical line of winding positions. It states that the

As a technical scheme for optimizing space utilization, the second technical scheme of the present invention is that the winding positions of the multiple winding groups are arranged in a frame and the winding positions are horizontally aligned. It describes that each layer is offset to the right end or the left end of the frame and laminated.

If the winding device has four stacked layers, the fourth technical scheme of the present invention is to arrange the winding position of the upper layer and the lower layer aligned with each other in one vertical line of winding positions. The winding position of the second layer, which is higher than the winding position of the side layer, is aligned with the winding position of the lower layer, and the winding position of the upper layer is slightly lower than the winding position of the third layer. In one group of guide elements, the two guide elements on the left are arranged offset to the winding position of the yarn, respectively, so as not to collide. It guides the yarn entry element in the winding position and the two right guide elements, respectively guiding the yarn to the two yarn entry elements in the winding position, which are arranged offset to the right in a non-colliding manner. Such an arrangement makes it possible to find an optimum balance between manufacturing costs and uniformity of the turning angles.

As a fifth technical scheme of the present invention, the winding position includes a traverse guide device for guiding the yarn along the axial direction of the driving roll at the winding position, and the yarn entering element and the driving roll The area covered by the locus of thread motion is an isosceles triangle. After the yarn passes through the yarn entry element, it is driven in reciprocating motion along the axial direction of the drive roll.

As a sixth technical scheme of the present invention, the guide elements of one group of guide elements corresponding to one vertical line of winding position are equidistantly spaced from each other.

In order to further optimize the correspondence between the guiding elements and the yarn entering elements, as a seventh technical scheme of the present invention, the leftmost guiding element and the rightmost guiding element are arranged to guide the yarn respectively. It guides to the yarn entry element in the winding position of the upper layer and to the yarn entry element in the winding position of the third layer.

In order to reduce the influence of the turning angle on bobbin formation as much as possible, the turning angle must be controlled below a certain value. As an eighth technical scheme of the present invention, in one vertical line of the winding position, the yarn deflection angle for guiding the yarn from the group of guiding elements to the yarn entering element is less than 10°.

Fig. 3 schematically shows the positional relationship of the points of projection of one vertical line of thread entry elements onto a connecting line connecting guiding elements according to the prior art; Fig. 3 schematically shows the positional relationship of the points of projection of one vertical line of the yarn entry elements onto the connecting line connecting the guiding elements according to the embodiment shown in Fig. 2; FIG. 4 is a structural schematic diagram of another embodiment of a winding device with one winding group according to the present invention; Fig. 6 schematically shows the positional relationship of the projection points of one vertical line of the yarn entry elements onto the connecting line connecting the guiding elements according to the embodiment shown in Fig. 5;

The winding device of a textile machine is a device formed solely by a winding group or a device formed together by placing several winding groups side by side. Further, each of the winding groups is formed in an orderly combination form from a plurality of winding positions for winding a wound body from a plurality of yarns. Prior to entry into the winding device, the yarn must undergo the necessary yarn treatments, ie heating, cooling, drawing, etc., via corresponding processing stations. Different machine types have different arrangements of processing positions.

The configuration of the winding position is illustrated in FIG. 1, which schematically shows a plan view of the winding position. As a plan view effect, the drive roll 5 below the bobbin 4 is shown in dashed lines. The bobbins 4 are pressed against this drive roll 5 so that they are parallel to it. The bobbin 4 can be approached or moved away from the drive roll 5 by means of the swivel arm 3 .

The winding position also includes a yarn entry element 9 for guiding the yarn 8 to the winding position. This thread entry element 9 is mounted correspondingly to the central section of the drive roll 5 . After passing through the thread entry element 9 the thread 8 reaches the traverse thread guide 6 and is then finally wound onto the bobbin 4 . The traverse yarn guide 6 is driven to reciprocate along the axial direction of the drive roll 5 by a traverse mechanism not present in FIG. Due to the joint limitation caused by the fixed yarn entry element 9 and the movable traverse yarn guide 6 , the area covered by the movement trajectory of the yarn 8 between them is an isosceles triangle 7 .

Continuing with the description of the construction of one said winding group. FIG. 2 is a structural schematic diagram of a winding device with one winding group. If the perspective view of FIG. 1 is defined as a vertical perspective view, the perspective view of FIG. 2 is a horizontal perspective view. The winding group contains 16 winding positions 2.1 to 2.16. These winding positions are vertically stacked in four layers. Each layer has four equally spaced adjacent winding positions. Each said winding position has the same structure as shown in FIG. It should be noted that the number of winding positions and the number of layers are for illustrative purposes only, the number of winding positions may be 12, or the number of layers to be stacked. The number may be three.

The winding positions 2.1-2.16 are housed inside the frame 1. As shown in FIG. The winding group has four horizontally arranged guide element groups. Each group has four guide elements. This results in a total of 16 guide elements 10.1-10.16. In this case the numbers are for illustrative purposes only and the distances between adjacent guide elements within each group of guide elements are equal. In this embodiment, the reason why the number of guide elements in one guide element group is four is that the guide elements and thread entry elements of the guide element group must be formed within the range of one vertical line. There is a one-to-one correspondence. As an example, the thread is guided from one of the four guide elements 10.1-10.4 to one of the four thread entry elements 9.1-9.4. Thread guidance must follow one basic principle: it should ensure that there are no collisions between the threads.

After being treated by a processing position upstream of the winding device, a yarn enters one of the guide elements 10.1-10.4 and then the yarn entry elements 9.1-10.4. 9.4 is guided upwards. The thread winding step is the final stage in which the bobbins are formed.

In order to better detail the distinguishing features of the invention, the description will be made by taking the winding positions 2.1, 2.5, 2.9, 2.13 of one vertical line as an example. The four layers are defined in order from top to bottom as top layer, third layer, second layer and bottom layer, respectively. The four winding positions 2.1, 2.5, 2.9, 2.13 are arranged neatly in a zigzag pattern with reference to the vertical direction. In particular, the upper layer winding position 2.1 and the third layer winding position 2.5 adjacent to each other are offset from each other in the left-right direction. Adjacent winding positions 2.5 of the third layer and winding positions 2.9 of the second layer are offset from each other in the left-right direction. Adjacent second layer winding positions 2.9 and lower layer winding positions 2.13 are offset from each other in the left-right direction. In addition, the winding position 2.1 of the upper 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 2.5 of the lower layer. Aligned with winding position 2.13. Therefore, the offset values for each adjacent winding position within one vertical line are equal. This is advantageous for the design, manufacturing and installation stages.

In addition to the above, while the spindle spacings between adjacent winding positions within a layer are equal, so are the spindle spacings in different layers. In the frame 1 housing the winding positions 2.1 to 2.16 all winding positions 2.1, 2.2, 2.3, 2.4 in the upper layer are offset towards the left edge of the frame 1 , all winding positions 2.5, 2.6, 2.7, 2.8 on the third layer are offset towards the right edge of the frame 1 and all winding positions on the second layer The take-up positions 2.9, 2.10, 2.11, 2.12 are offset towards the left frame 1, all the take-up positions 2.13, 2.14, 2 in the lower layers. .15, 2.16 are offset towards the frame 1 right edge. Likewise, each offset value between adjacent layers is equal.

A thread has to be guided from one said guide element to one said thread entry element which has a corresponding relation to this guide element. Correspondence is set by the following means. As an illustrative example, by considering one vertical line of winding positions 2.1, 2.5, 2.9, 2.13, the guide elements 10.1, 10.2, 10.3, 10 . 4, the left-hand guide elements 10.1, 10.2 each arrange one thread offset to the left within said one vertical line of the winding position. 3 to the yarn entry elements 9.1, 9.3 of the selected winding position 2.1, 2.9. The guide elements 10.3, 10.4 provided on the right-hand side each hold one thread at the winding position 2.5 which is arranged offset to the right within said one vertical line of winding positions. , 2.13 to the thread entry elements 9.2, 9.4. In particular, the guide elements 10.1, 10.4 provided at the two ends within the group of guide elements each lead one thread to the thread entry element 9.1 at the winding position 2.1 of the upper layer. 1 and the yarn entry element 9.2 at the winding position 2.5 of the third layer. The reasons for designing such yarn paths are detailed below by referring to FIGS.

FIG. 3 schematically shows the positional relationship of the projection points of one vertical line of the thread entry elements onto the connecting line connecting the guiding elements according to the prior art. FIG. 4 schematically shows the positional relationship of the projection points of one vertical line of the thread entry elements onto the connecting line connecting the guiding elements according to the embodiment shown in FIG. As a result of being guided from the guide element 10.1 to the corresponding thread entry element 9.1, the thread is deflected at the deflection angle A shown in FIG. 3 as the angle formed with respect to the vertical line. This deflection angle A is a factor influencing the frictional forces and thread tensions applied to the thread as it passes through the thread guides, which ultimately affect the formation of the bobbin. In order to produce bobbins that are as uniform as possible, it is desirable to reduce the differences in thread-to-thread frictional forces and thread tensions as much as possible. In order to achieve this aim, it is further desired to reduce the value of the deflection angle A so that the difference in the deflection angle A from thread to thread is as small as possible.

As can be seen from FIG. 3, according to the prior art the guiding elements 9.1, 9.2, 9.3, 9.4 in one vertical line are aligned with each other. Reference numeral 11 is a connecting line through all said guiding elements. The reference numerals 10.1′, 10.2′, 10.3′, 10.4′ on this connecting line 11 refer to the guide elements 10.1, 10.2, 10.3, 10 on the connecting line 11 respectively. .4 position. The projection points of the aligned thread entry elements 9.1, 9.2, 9.3, 9.4 on the connecting line 11 overlap as reference numeral 9'. The value of the deflection angle A is thus determined by the distance from reference 10.1' to reference 9' and from reference 9' to the yarn entry element 9.1. The distance between 9' and 10.2' is indicated as a, the distance between 9' and 10.3' is indicated as b, and the distance between 9' and 10.3' is indicated as b. .4' is indicated as c and the distance between reference numerals 9' and 10.1' is indicated as d. As can be seen, the differences between a, b, c and d are relatively large.

FIG. 4 applies for direct comparison with FIG. FIG. 4 shows the positional relationship between projection points in the embodiment shown in FIG. According to FIG. 4, the thread entry elements 9.1 of the upper layer are aligned with the thread entry elements 9.3 of the second layer and both are connected at an overlapping projected point indicated as reference numeral 12. It is projected onto line 11 . The yarn entry elements 9.2 of the third layer are aligned with the yarn entry elements 9.4 of the lower layer, both projected onto the connecting line 11 at overlapping projection points indicated as reference numeral 13. It is The yarn entry elements 9.1 of the upper layer are arranged laterally offset with respect to the yarn entry elements 9.2 of the third layer. The yarn entry elements 9.3 of the second layer are arranged laterally offset with respect to the yarn entry elements 9.4 of the lower layer. The distance between reference 12 and reference 10.2' is indicated as e, the distance between reference 13 and reference 10.3' is indicated as f, and the distance between reference 13 and reference 10.3' is indicated as f. 10.4' is indicated as g and the distance between reference 12 and reference 10.1' is indicated as h.

In each embodiment shown in FIGS. 3 and 4, the distance from each guide element 9.1, 9.2, 9.3, 9.4 to the corresponding projection point onto the connecting line remains unchanged. is. Accordingly, the smaller the distance from the guide element to the point of projection of the corresponding thread entry element onto the connecting line, the smaller the deflection angle A.

After comparing FIG. 3, which shows the features of the prior art, and FIG. 4, which shows the features of the present invention, the configuration of the winding device according to the present invention can be compared with the differences in the values of a, b, c, and d. , the differences in the values of e, f, g, and h can be reduced. Furthermore, the value of reference h is reduced compared to reference d and the value of reference e is reduced compared to reference c. The resulting technical effect is that in one vertical line of the winding position, the deflection angles of each yarn are as uniform as possible, with relatively large deflection angles initially leading to smaller deflection angles. It is decreasing.

FIG. 5 is a structural schematic diagram of another embodiment of a winding device with 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 said yarn entry elements 9.1-9.4 in one vertical line of winding position are arranged staggered without alignment. , and therefore there are no overlapping projection points on the connecting line 11 .

FIG. 6 schematically shows the positional relationship of the projection points of one vertical line of the thread entry elements onto the connecting line connecting the guide elements according to the embodiment shown in FIG. The point of projection of the thread entry element 9.1 onto the connecting line 11 is indicated as 9.1' and the point of projection of the thread entry element 9.2 onto the connection line 11 is designated 9.2. ', the point of projection of the thread entry element 9.3 onto the connecting line 11 is indicated as reference 9.3', the point of projection of the thread entry element 9.4 onto the connection line 11 is , with the reference numeral 9.4'. the distance between 9.3′ and 10.2′ is indicated as i, the distance between 9.4′ and 10.3′ is indicated as j, The distance between 9.2' and 10.4' is indicated as k and the distance between 9.1' and 10.1' is indicated as l. By comparison with the embodiment shown in FIG. 4, the differences in the values of i, j, k, l are further reduced relative to the differences in the values of e, f, g, h. Therefore, the difference in the value of the deflection angle A from yarn to yarn is further reduced.

Distinguishing features of the present invention are shown in FIGS. 2, 4 and 5, 6 respectively. 2 and 4, each of the winding positions in one vertical line projected onto the connection line of the guide elements of the group of guide elements in one vertical line of winding positions. It illustrates that the projection points of the yarn entry elements are distributed overlappingly between the leftmost and rightmost guide elements of said group of guide elements. The embodiment shown in FIGS. 5 and 6 shows the configuration of each winding position in one vertical line projected onto the connecting line of the guide elements of the group of guide elements in one vertical line of winding positions. It illustrates that the projection points of the thread entry elements are all dispersedly distributed between the leftmost guide element and the rightmost guide element of the group of guide elements. What has been achieved is that all bobbins formed have more uniform parameters.

The number of winding groups is chosen for exemplary purposes only. This may be 10 groups or 12 groups depending on the specifications of different textile machines. In order to reduce the influence of the turning angle on the bobbin formation as much as possible, the turning angle should be controlled below a certain value, preferably below 10°.
