Description

Technical Field

[0001] The utility model relates to the technical field of spinning production, in particular to a yarn conveying device of a winding machine. Background Art

[0002] Winders, a crucial component of the textile industry, are primarily used to wind yarn spun from spinning machines (spindles) into preformed bobbins for use in subsequent processes such as dyeing, warping, and weaving. Advances in technology have not only improved production efficiency but also significantly reduced labor intensity. The yarn transfer mechanism, a key component of the winder, ensures the smooth transfer of yarn from the bobbin or tube to the new tube, ensuring yarn continuity and consistent tension.

[0003] In order to realize automatic yarn loading, the spindles are transported to the winding machine and placed on the winding machine for winding by a robot. Currently, there is a method of using intelligent robots to transport the spindles to the winding machine, but the cost of intelligent robots is high and they are prone to abnormalities. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a yarn feeding conveying device for a bobbin winder, which solves the technical problems of the existing automatic yarn feeding devices that are high in cost and prone to abnormalities.

[0005] According to an embodiment of the present invention, a yarn upper conveying device of a winding machine is described, comprising a straight conveying structure and an annular conveying structure uniformly distributed along the length direction of the straight conveying structure, a spindle conveying path is left between the straight conveying structure and the annular conveying structure, an upper yarn position is provided between adjacent annular conveying structures, the upper yarn position is connected to the spindle conveying path, and each of the upper yarns corresponds to a winding machine.

[0006] The technical principle of the present invention is: after the spindle enters the spindle transmission path, it will be clamped by the linear transmission structure and the annular transmission structure on both sides and pushed to move forward. When it approaches the upper yarn position, if there is no spindle on the upper yarn position, the opening and closing mechanism is in an open state, so the spindle will be pushed to the side of the upper yarn position, and because of the push of subsequent spindles, it will be squeezed into the upper yarn position. At this time, because the spindle has occupied the upper yarn position, the subsequent spindles cannot enter and will be pushed by the linear transmission structure to continue moving forward until they enter an upper yarn position without a spindle. Because no intelligent equipment is used, it is not easy to have abnormalities, and the structure is simple and the cost is low.

[0007] Specifically, each winding machine needs to be provided with a structure such as a robot for placing the spindle in the upper yarn position onto the winding machine.

[0008] The specific upper yarn conveying device may be provided with other structures to connect the upper yarn conveying device end to end to achieve the turnover of the spindles.

[0009] A dedicated chassis can be provided on the lower side of the specific spindle, and the chassis is placed on the spindle conveying path for transmission, while the spindles are placed on the chassis to avoid collisions between the spindles.

[0010] Compared with the existing technology, the present invention has the following beneficial effects: by coordinating the yarn loading position with the linear transmission structure and the annular transmission structure, it solves the technical problems of the existing automatic yarn loading device that is high in cost and prone to abnormalities.

[0011] Furthermore, the linear transmission structure includes an active roller, a passive roller, and a linear synchronous belt connecting the active roller and the passive roller.

[0012] Furthermore, support rollers are evenly distributed along the straight line between the active roller and the passive roller, all of the support rollers are meshed and connected with the linear synchronous belt, and each of the support rollers is aligned with an annular transmission structure.

[0013] Furthermore, the annular transmission structure includes a driving wheel and three reversing wheels and an annular synchronous belt connecting the driving wheel and the three reversing wheels. The annular synchronous belt is a quadrilateral structure, and one side of the annular synchronous belt is parallel to the length direction of the linear transmission structure.

[0014] Furthermore, the upper yarn position is an obtuse triangle structure, and the upper yarn position is away from the inner angle of the linear transmission structure and inclined toward the transmission direction of the linear transmission structure.

[0015] Furthermore, a V-shaped block is provided at the inner corner of the upper yarn position away from the linear transmission structure.

[0016] Furthermore, the linear transmission structure and the annular transmission structure are respectively provided with transmission motors.

[0017] Furthermore, the active roller is connected to a transmission motor, and the annular transmission structure is connected to the supporting roller by gear meshing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] like Figure 1-2 As shown, the upper yarn conveying device of the winding machine includes a straight conveying structure 100 and an annular conveying structure 200 uniformly distributed along the length direction of the straight conveying structure 100, wherein a spindle conveying path 300 is left between the straight conveying structure 100 and the annular conveying structure 200, and an upper yarn position 310 is provided between adjacent annular conveying structures 200. Each upper yarn corresponds to a winding machine, and the upper yarn position 310 is connected to the spindle conveying path 300, so that the spindle can enter the upper yarn position 310 through the spindle conveying path 300, and then be grabbed by the robot equipped with the winding machine, and then the winding work is carried out.

[0025] like Figure 1 As shown, the linear transmission structure 100 includes an active roller 110 and a passive roller 120 and a linear synchronous belt 130 connecting the active roller 110 and the passive roller 120. Specifically, support rollers 140 are evenly distributed along the linear transmission between the active roller 110 and the passive roller 120. All support rollers 140 are engaged with the linear synchronous belt 130. Each support roller 140 is aligned with an annular transmission structure 200. Specifically, the support rollers 140 cooperate with the annular transmission structure 200 to apply a continuous and stable clamping force to the spindles on the spindle transmission path 300.

[0026] like Figure 1 As shown, the annular transmission structure 200 includes a driving wheel 210 and three reversing wheels 220 and an annular synchronous belt 230 connecting the driving wheel 210 and the three reversing wheels 220. The annular synchronous belt 230 is a quadrilateral structure, that is, the driving wheel 210 and the three reversing wheels 220 are just located at the four corners of the quadrilateral structure. One side of the annular synchronous belt 230 is parallel to the length direction of the straight transmission structure 100, ensuring that the spindles are transmitted along the spindle transmission path 300.

[0027] Specifically, the upper yarn position 310 is an obtuse triangle structure. The upper yarn position 310 is away from the inner angle of the linear transmission structure 100 and is inclined toward the transmission direction of the linear transmission structure 100, so as to prevent the spindle entering the upper yarn position 310 from leaving the upper yarn position 310 again due to the transmission of the annular transmission structure 200.

[0028] like Figure 1 As shown, the linear transmission structure 100 and the annular transmission structure 200 are respectively provided with a transmission motor 111 , and the two transmission motors rotate synchronously.

[0029] like Figure 1-2 As shown, a V-shaped block 311 is provided at the inner corner of the upper yarn position 310 away from the linear transmission structure 100 , so that the spindle will not be affected by the transmission of the annular transmission structure 200 after entering the upper yarn position 310 .

[0030] Example 2

[0031] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the active roller 110 is connected to the transmission motor 111, and the annular conveying structure 200 and the supporting roller 140 are connected by meshing with the gear 141, so that only one transmission motor 111 is used, which helps to reduce costs, but the driving force is relatively small.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
