[0049] Yarn bobbins are crucial components in the textile industry. Yarn is wound onto bobbins for various processing steps. The bobbin holder, a specialized part of textile equipment, plays a vital role in textile production, typically used to hold the yarn bobbins used in weaving and provide the yarn source. Currently, the yarn bobbins are generally hung on the bobbin holder manually. Due to the large amount of yarn used in weaving, this manual hanging process is labor-intensive and demanding.

[0050] In view of this, the present invention proposes an automatic yarn hanging device for automatically hanging yarn bobbins, replacing manual operation with a belt, which can improve work efficiency, reduce labor intensity, and save labor costs. Figures 1 to 5 The image shows an embodiment of the automatic yarn-feeding device provided by the present invention.

[0051] like Figure 1 and Figure 2As shown, the automatic yarn hanging device 100 proposed in this invention includes a material carrier platform 1, a yarn bobbin hanger 2, and a transfer mechanism 3. The material carrier platform 1 is used to place a yarn tray 200 containing multiple yarn bobbins placed vertically. The yarn bobbin hanger 2 is spaced apart from and opposite to the material carrier platform 1 in the front-to-back direction. The yarn bobbin hanger 2 includes a hanging seat 21 extending in the vertical direction. The hanging seat 21 has multiple hanging posts 22 extending in the front-to-back direction on both sides of the front-to-back direction. The multiple hanging posts 22 are arranged in an array for hanging yarn bobbins. The transfer mechanism 3 has a transfer part 31. The transfer part 31 can move in the vertical, left-to-right, and front-to-back directions. The transfer part 31 can pick up the vertically placed yarn bobbins on the material carrier platform 1, rotate them, and hang them on the hanging posts 22.

[0052] In the technical solution of the present invention, the automatic yarn hanging device 100 includes a material carrier 1, a yarn tube hanger 2, and a transfer mechanism 3. The material carrier 1 is used to place a yarn tray containing multiple yarn tubes placed vertically. The yarn tube hanger 2 is spaced apart from and opposite to the material carrier 1 in the front-back direction. The yarn tube hanger 2 includes a hanging seat 21 extending in the vertical direction. The hanging seat 21 has multiple hanging posts 22 extending in the front-back direction on both sides of the front-back direction. The multiple hanging posts 22 are arranged in an array for hanging yarn tubes. The transfer mechanism 3 has a transfer part 31. The transfer part 31 can move in the vertical, left-right, and front-back directions. The transfer part 31 can pick up the vertically placed yarn tubes on the material carrier 1, rotate them, and hang them on the hanging posts 22. Thus, the transfer unit 31 can pick up the vertically placed yarn bobbin on the loading platform 1, rotate it, and hang it on the hanging column 22 to complete the automatic hanging of the yarn bobbin. The automatic yarn hanging device 100 automatically hangs the yarn bobbin, replacing manual operation, which improves work efficiency, reduces labor intensity, and saves labor costs.

[0053] The transfer unit 31 can pick up the vertically placed yarn bobbins on the loading platform 1, rotate them, and hang them on the hanging column 22 to achieve automatic hanging of the yarn bobbins. Specifically, in this embodiment, as follows: Figure 3 and Figure 4As shown, the transfer unit 31 includes a connecting seat 311, a parallel pneumatic gripper structure 312, and a rotary cylinder 313. The connecting seat 311 includes a first seat section 311a extending in the left-right direction and a second seat section 311b extending in the front-back direction. The parallel pneumatic gripper structure 312 is mounted on the front side of the first seat section 311a and includes two movable grippers 312a extending in the left-right direction and arranged opposite each other. The two movable grippers 312a can move closer to each other to jointly grip the yarn bobbin or move away from each other to release the yarn bobbin. The cylinder rod end of the rotary cylinder 313 is connected to the second seat to drive the connecting seat 311 to rotate. Thus, the rotation of the rotary cylinder 313 allows the parallel pneumatic gripper structure 312 to rotate toward the loading platform 1 or toward the yarn bobbin hanger 2, thereby picking up the vertically placed yarn bobbin on the loading platform 1 and rotating it to hang it on the hanging post 22 on the yarn bobbin hanger 2.

[0054] To facilitate easier and more accurate hanging of the yarn bobbin on the hanging post 22, a yarn bobbin leveling structure is provided. In this embodiment, as shown... Figure 3 and Figure 4 As shown, the transfer mechanism 3 further includes a top support structure 32, which includes two supports 321 and an adjusting member 322. The two supports 321 are installed on the front side of the first base section 311a and located below the parallel pneumatic gripper structure 312. The two supports 321 are spaced apart in the left-right direction. The adjusting member 322 includes an adjusting rod 322a extending in the left-right direction and two connecting arms 322b located at the left and right ends of the adjusting rod 322a and extending in the same direction. Each connecting arm 322b is rotatably installed on each support 321 along the left-right axis so that the adjusting rod 322a can move upward to contact the yarn bobbin. Thus, when the two movable claws 312a jointly hold the yarn bobbin and hang it on the hanging post 22, the adjusting rod 322a can move upward and contact the yarn bobbin so that the center line of the yarn bobbin is collinear or parallel to the hanging post 22, so as to quickly hang the yarn bobbin on the hanging post 22 and improve the hanging efficiency of the yarn bobbin.

[0055] Specifically, in this embodiment, such as Figure 3As shown, a connecting shaft 322c is provided between the two connecting arms 322b, and the connecting shaft 322c and the adjusting rod 322a are spaced apart in the front-rear direction; the top support structure 32 also includes a first drive motor 323 and a transmission mechanism 324. The first drive motor 323 is installed on the front side of the second seat section 311b and is located below the adjusting member 322. The output shaft of the drive motor extends in the left-right direction; the transmission mechanism 324 includes a first pulley, a second pulley 324a and a transmission belt 324b. The first pulley is installed on the shaft end of the output shaft, the second pulley 324a is installed on the connecting shaft 322c, and the transmission belt 324b is sleeved on the outside of the first pulley and the second pulley 324a to transmit the rotation of the output shaft to the connecting shaft 322c, so that the adjusting rod 322a moves upward. Thus, the first drive motor 323 operates, driving the connecting shaft 322c to rotate, so that the adjusting rod 322a can move upward to contact the yarn bobbin, thereby leveling the yarn bobbin.

[0056] To enable the transfer unit 31 to better pick up and hang the yarn bobbin, a visual guidance structure is provided. Specifically, in this embodiment, such as... Figure 3 As shown, the automatic yarn hanging device 100 also includes a camera component 33, which is installed on the front side of the second base section 311b and located above the parallel gripper structure 312. The camera component 33 is electrically connected to the rotary cylinder 313 and the parallel gripper structure 312. Thus, the camera component 33 can obtain positional image information of the vertically placed yarn bobbin on the loading platform 1, facilitating the adjustment of the rotation angle of the rotary cylinder 313 and the position of the parallel gripper structure 312. This allows the device to pick up the yarn bobbin, rotate it, and hang it on the hanging column 22, improving the accuracy of the gripping and hanging of the transfer unit 31.

[0057] The transfer part 31 is movable along the vertical, horizontal, and front-back directions to pick up and hang the yarn tube. Specifically, in this embodiment, as... Figure 1As shown, the transfer mechanism 3 further includes a body 34, a movable beam 36, and a mounting beam 37. The body 34 includes two support frames spaced apart in the left-right direction and a load-bearing frame 341 mounted above the two support frames. The yarn bobbin hanger 2 and the material platform 1 are correspondingly located on both sides of the support frames in the front-back direction, and both are located below the load-bearing frame 341. The movable beam 36 is mounted on the load-bearing frame 341 and is movable in the left-right direction. The mounting beam 37 is mounted on the movable beam 36 and is movable in the front-back direction. The transfer part 31 is movably mounted to the mounting beam 37 in the vertical direction. In this way, the transfer part 31 is movable in the vertical, left-right, and front-back directions, so that it can move from above the material platform 1 to the area near the yarn bobbin hanger 2, thereby hanging the yarn bobbin on the hanging column 22. It should be noted that the bearing frame 341 has linear motion modules extending in the left and right directions on the upper surfaces of its two front-to-back sidewalls. Similarly, the movable beam frame 36 has linear motion modules extending in the front-to-back direction on its left side, and the mounting beam 37 has linear motion modules extending in the vertical direction on its left side. Thus, the linear motion modules allow the movable beam frame 36 to move in the left and right directions, the mounting beam 37 to move in the front-to-back direction, and the transfer part 31 to be movably mounted to the mounting beam 37 in the vertical direction. Since the linear motion modules are a conventional structure in this field, their specific structure will not be described in detail here, and the specific model of the linear motion modules is not limited; they can be selected according to actual conditions, as long as they meet the usage requirements.

[0058] The yarn tray holding the yarn bobbin can be conveyed to the corresponding position via the loading platform 1. In this embodiment, as... Figure 1 and Figure 5 As shown, the material carrier 1 includes a material carrier body 11, a conveying group 12, and a driving mechanism 13. The conveying group 12 includes multiple idler rollers 121 spaced apart along the left and right sides. Each idler roller 121 is rotatably mounted on the material carrier body 11 along a front-back axis for placing the yarn tray. The driving mechanism 13 includes a second driving motor 131 and multiple transmission connecting belts 132. Each transmission connecting belt 132 is sleeved and connected to two adjacent idler rollers 121. The second driving motor 131 is mounted on the material carrier body 11, and its output shaft extends in the front-back direction and is driven and connected to one of the multiple idler rollers 121. Thus, by operating the second driving motor, the connected idler rollers 121 rotate. Since two adjacent idler rollers 121 are connected by the transmission connecting belts 132, the multiple idler rollers 121 rotate synchronously to convey the yarn tray to the corresponding position.

[0059] To prevent the yarn tray from moving excessively and deviating from the set position, a movement limiting structure is provided. In this embodiment, such as... Figure 5 As shown, the automatic yarn feeding device 100 also includes a yarn tray limiting structure 4. The yarn tray limiting structure 4 includes a mounting plate 41 and a limit switch. The mounting plate 41 is located on one side of the material platform body 11 in the left-right direction and extends in the up-down direction. The limit switch is located on the side of the mounting plate 41 facing the material platform body 11 to limit the movement of the yarn tray. In this way, the movement of the yarn tray is limited by the limit switch, allowing it to move to a specific position.

[0060] To ensure more reliable upper limit positioning of the yarn tray on the loading platform 1, a locking structure is provided. In this embodiment, as shown... Figure 5 As shown, the material platform body 11 is equipped with two abutting cylinders 111 extending in the front-to-back direction. The two abutting cylinders 111 are spaced apart and opposite to each other in the front-to-back direction, and are both electrically connected to the limit switch. The cylinder rod of each abutting cylinder 111 is provided with an abutting plate 112. The two abutting plates 112 are used to clamp the yarn tray together when the yarn tray moves to contact the limit switch. Thus, after the yarn tray moves to contact the limit switch, the two abutting cylinders 111 connected to the limit switch receive a signal to open, and the cylinder rods of each abutting cylinder 111 extend so that both abutting plates 112 abut against the yarn tray, thereby achieving the locking and positioning of the yarn tray.

[0061] In this embodiment, as Figure 2 As shown, the automatic yarn hanging device 100 also includes a hanging bracket guide group 5 located in front of the yarn tube hanger 2. The hanging bracket guide group 5 includes two guide plates 51 extending in the left-right direction. Each guide plate 51 has a guide groove 52 on its upper end surface, and the sidewalls of the guide grooves 52 pass through the two sides of the guide plate 51 in the left-right direction. The bottom of the yarn tube hanger 2 is provided with two moving wheels 23, which are slidably installed in the two guide grooves 52. By providing the moving wheels 23 at the bottom of the yarn tube hanger 2, the yarn tube hanger 2 can be easily moved to the yarn-using position after being filled with yarn tubes. By providing the two guide plates 51, the yarn tube hanger 2 is moved and guided along a set path to meet the needs of yarn tube hanging.

[0062] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
