Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a yarn loading and unloading device and a textile production line having the same. Background Technology

[0002] After the yarn cones are produced on the winding machine, they are usually transferred via conveyor lines and further processed according to different customer needs. For example, they may be packed into woven bags for full-package shipping, packed into cartons for full-box shipping, or stacked individually for steaming, transfer, or shipping. Among these processes, achieving automated stacking of individual yarns is a key step in improving production line efficiency.

[0003] In the automated yarn bobbin stacking process, the yarn bobbin picking and placing device is the core device for realizing the orderly arrangement of individual yarn bobbins. In order to achieve single yarn stacking, the existing automated yarn bobbin picking and placing devices usually use a yarn picking robot to remove the yarn bobbin from the conveyor line and place it on an inclined slide. The yarn bobbin rolls to a baffle for positioning by gravity. Then, a flipping device flips the yarn bobbin from a lying position to a position with the small end facing up. Next, a yarn pushing device pushes the yarn bobbin to a designated position, and then a yarn clamping device clamps, lifts and moves the yarn bobbin to arrange it in a row. Finally, a stacking robot removes the entire row of yarn bobbins.

[0004] In existing automatic yarn bobbin loading and unloading devices, the yarn bobbins rely on their own weight to roll on the slide during operation. The rolling position of the yarn bobbins is uncertain, and the yarn picking robot must wait until the yarn bobbins have completely rolled off the slide before it can perform the next yarn picking action. There is a lot of waiting time in the yarn picking robot's operation process, which limits the improvement of production efficiency in the automatic yarn bobbin loading and unloading process. Utility Model Content

[0005] In view of this, the present invention provides a yarn package loading and unloading device and a textile production line having the same, so as to solve the problem of low working efficiency of existing automatic yarn package loading and unloading devices.

[0006] In a first aspect, this utility model provides a yarn package taking and placing device, comprising: Support components; A yarn turning mechanism is mounted on a support member. The yarn turning mechanism includes a yarn turning assembly and a first drive assembly. The yarn turning assembly is rotatably mounted on the support member. The drive end of the first drive assembly cooperates with the yarn turning assembly to drive the yarn turning assembly to rotate. The yarn turning assembly is provided with a yarn receiving part. The yarn receiving part has a first state suitable for receiving the yarn body in a lying posture, and a second state after the yarn turning assembly rotates around the support member and carries the yarn body to a standing posture. The yarn feeding mechanism is installed on the support member. The yarn feeding mechanism includes a clamping component and a conveying component. The clamping component is correspondingly arranged with the yarn receiving part. The clamping component is suitable for clamping the standing yarn body. The clamping component is installed on the conveying component. The conveying component is suitable for conveying the yarn body clamped on the clamping component to a preset work position.

[0007] When the yarn bobbin picking and placing device is in operation, firstly, an external yarn picking device moves the yarn bobbin in a lying position and places it on the yarn receiving part of the yarn bobbin flipping mechanism, at which point the yarn receiving part is in the first state. Then, the first drive component actuates, driving the entire yarn rotating component to rotate around its rotation center. During this process, the yarn receiving part, carrying the yarn bobbin, changes from the first state to the second state, thus flipping the yarn bobbin from a lying position to an upright position. Next, the clamping component of the yarn arranging mechanism actuates, clamping the yarn bobbin now in an upright position. Then, the transport component drives the clamping component, along with the clamped yarn bobbin, to move together, finally transporting and releasing the yarn bobbin to a preset workstation, completing the picking, placing, and arranging process for a single yarn bobbin. By integrating the yarn bobbin flipping and arranging functions into one unit, the yarn rotating component achieves the flipping of the yarn bobbin's posture, and the yarn arranging mechanism undertakes the subsequent transport and arrangement, replacing the complex process of relying on the yarn bobbin's own weight to roll, multiple positioning, and individual lifting in the prior art. Because the yarn package can be directly clamped and transferred after flipping, without waiting for other auxiliary actions to be completed, the entire picking and placing process is more compact, which can effectively shorten the placement and arrangement time of the yarn package and thus improve the production efficiency of the entire textile production line.

[0008] In one optional embodiment, the yarn-turning assembly includes a rotating shaft rotatably mounted on a support member. The yarn-bearing part includes a yarn-receiving member and a yarn-blocking member arranged at an angle. Both the yarn-receiving member and the yarn-blocking member are arranged perpendicular to the rotating shaft. When the yarn-bearing part is in a first state, both the yarn-receiving member and the yarn-blocking member are inclined upwards, and the lying-down yarn body is suitable for receiving between the yarn-receiving member and the yarn-blocking member.

[0009] When the yarn package turning mechanism needs to receive yarn, the yarn turning assembly is in its initial position. At this time, the receiving and blocking components, which are perpendicular to the rotation axis, are both tilted upwards. After the lying-down yarn package is placed by the external robot arm, the bottom surface of the yarn package rests on the receiving component, while the end face of the yarn package abuts against the blocking component, thus being stably supported between the receiving and blocking components. When the first drive assembly drives the rotation axis to rotate, the receiving and blocking components rotate together with the rotation axis, thereby causing the yarn package to turn from a lying-down position to a standing position. The angled receiving and blocking components together form a stable support structure, which effectively restricts the position of the yarn package when supporting it, preventing it from slipping or shifting, ensuring the accuracy and consistency of the yarn package's positioning, and guaranteeing that the yarn package can be turned into place during subsequent turning.

[0010] In one alternative embodiment, the yarn splicing member includes at least two yarn splicing rods, and the yarn blocking member includes at least two yarn blocking rods.

[0011] When receiving a reclining yarn package, the weight of the package is shared and supported by at least two yarn-receiving rods, and the axial movement of the package is restricted by at least two yarn-stopping rods. Multiple yarn-receiving rods and yarn-stopping rods are distributed along the length of the yarn package, achieving line or surface contact support and restraint. The structure of at least two yarn-receiving rods and at least two yarn-stopping rods increases the contact points and support range with the yarn package, making the support more stable and effectively preventing deflection, twisting, or localized damage to the yarn package due to single-point force during receiving or turning, thus improving the stability and safety of the yarn package during turning.

[0012] In one optional embodiment, the first driving component is a telescopic driving component, and the yarn rotating component further includes a yarn rotating rod. One end of the yarn rotating rod is fixedly connected to the rotating shaft, and the other end is hinged to the driving end of the first driving component. The yarn rotating rod is perpendicular to the rotating shaft.

[0013] When the first drive assembly operates as a telescopic drive, the linear motion of its drive end is transmitted to the yarn-rotating pull rod through the hinge point. Since one end of the yarn-rotating pull rod is fixedly connected to and perpendicular to the rotation axis, it converts the linear tension or thrust of the first drive assembly into a torque that rotates the rotation axis, thereby driving the entire yarn-rotating assembly, including the yarn receiving and blocking components, to rotate around the axis of rotation. Utilizing the yarn-rotating pull rod to convert linear motion into rotational motion results in a simple, reliable structure with high transmission efficiency. The hinged connection between the yarn-rotating pull rod and the first drive assembly can accommodate small changes in angle during movement, reducing motion interference and wear, and ensuring the smoothness and reliability of the yarn-rotating assembly's rotation.

[0014] In one alternative embodiment, the first drive component is a linear drive cylinder, the cylinder body of which is fixedly mounted on a support, and the piston rod of the linear drive cylinder is hinged to the yarn-rotating pull rod.

[0015] The cylinder body of the linear drive cylinder is fixedly mounted on a support to provide supporting reaction force. When the piston rod of the linear drive cylinder extends or retracts, the piston rod pulls or pushes the yarn-rotating pull rod through the hinge point. The yarn-rotating pull rod converts the linear motion of the piston rod of the linear drive cylinder into the rotational motion of the rotating shaft, thereby realizing the flipping action of the yarn-rotating assembly. Using a linear drive cylinder as the first drive component is convenient to control, has a fast response speed, and can provide a large driving force, which helps to improve the working efficiency of the entire device.

[0016] In one alternative embodiment, the clamping assembly includes a pair of opposing clamping arms and at least one second drive assembly adapted to drive the pair of clamping arms to move closer to or further away from each other.

[0017] When a standing yarn package needs to be clamped, at least one second drive component activates, driving a pair of opposing clamping arms to move closer together, embracing the yarn package from both sides and thus clamping it securely. When the yarn package needs to be released, the second drive component drives the pair of clamping arms to move away from each other, releasing the yarn package. By directly controlling the opening and closing of the pair of clamping arms through the second drive component, the opposing clamping arms can apply force evenly from both sides, ensuring clamping stability and alignment, preventing the yarn package from tilting or tipping over during clamping, and guaranteeing the reliability of subsequent transportation.

[0018] In one optional embodiment, each end of the yarn clamping arm is provided with a yarn clamping plate, and the opposite sides of a pair of yarn clamping plates are recessed.

[0019] When a pair of clamping arms are driven closer together by the second drive assembly, a pair of clamping plates located at the ends of the clamping arms approach from both sides of the yarn package. Because the opposing sides of the clamping plates are concave, the concave curved surface better conforms to the cylindrical outer contour of the standing yarn package, achieving a wrap-around clamping effect. The concave clamping plate increases the contact area with the outer wall of the yarn package, resulting in a more uniform distribution of clamping force and avoiding surface damage to the yarn package that may be caused by point or line contact. Simultaneously, the concave curved surface structure helps to position the yarn package during clamping, further improving clamping stability and preventing slippage.

[0020] In one alternative embodiment, the transport component includes a slide rail pair, a third drive component, and a sliding platform. The sliding platform is slidably mounted on the slide rail pair, the third drive component drives the sliding platform to slide along the slide rail pair, and the clamping component is mounted on the sliding platform.

[0021] The sliding platform is mounted on the support via a slide rail pair and can slide along the direction defined by the slide rail pair. The clamping assembly is fixedly mounted on the sliding platform. When the clamping assembly clamps the yarn package, the third drive assembly is activated, driving the sliding platform to move along the slide rail pair, thereby moving the clamping assembly and the clamped yarn package together from the yarn package turning mechanism to the preset arrangement position. The slide rail pair provides guidance for the sliding platform, ensuring the movement trajectory of the yarn package during transportation and ensuring that the yarn package can be transported to the designated position.

[0022] In one alternative embodiment, a timing belt is wound around the slide rail pair, and the sliding platform is fixedly mounted on the timing belt. At least one end of the timing belt is wound around the drive end of the third drive component, and the third drive component drives the timing belt to reciprocate to carry the sliding platform to slide along the slide rail pair.

[0023] The sliding platform is fixedly mounted on a synchronous belt wound around a slide rail pair. When the third drive component is running, its drive end drives the synchronous belt to perform a cyclic reciprocating motion. Since the sliding platform is fixedly connected to the synchronous belt, the motion of the synchronous belt is directly converted into the reciprocating linear motion of the sliding platform along the slide rail pair. This facilitates long-distance conveying of the sliding platform, ensures the accuracy of transporting the yarn bobbins to the preset work position, and improves the reliability of the entire device in arranging the yarn bobbins.

[0024] Secondly, this utility model also provides a textile production line having the yarn loading and unloading device described in this application.

[0025] Since the textile production line includes a yarn loading and unloading device, which has the same effect as the yarn loading and unloading device, it will not be described in detail here. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, a yarn loading and unloading device is provided, including a support member 1 for mounting and supporting other mechanisms. In this embodiment, the support member 1 is a support frame structure. In some other embodiments, the support member 1 may also be a support platform or other support structure. A yarn turning mechanism 2 and a yarn feeding mechanism 3 are mounted on the support member 1.

[0036] The yarn turning mechanism 2 includes a yarn turning component and a first drive component 201. The yarn turning component is rotatably mounted on the support member 1. The drive end of the first drive component 201 cooperates with the yarn turning component to drive the yarn turning component to rotate. The yarn turning component is provided with a yarn receiving part, which has a first state suitable for receiving the yarn body 7 in a lying position, and a second state after the yarn turning component rotates around the support member 1 and carries the yarn body 7 to a standing position. The yarn feeding mechanism 3 includes a clamping component and a conveying component. The clamping component is correspondingly arranged with the yarn receiving part and is suitable for clamping the standing yarn body 7. The clamping component is mounted on the conveying component, which is suitable for conveying the yarn body 7 clamped on the clamping component to a preset work position.

[0037] When the yarn package pick-and-place device is in operation, firstly, the external yarn picking device moves the yarn package body 7, which is in a lying position, and places it on the yarn receiving part of the yarn package flipping mechanism 2. At this time, the yarn receiving part is in the first state. Subsequently, the first drive component 201 is activated, driving the entire yarn turning component to rotate around its rotation center. During this process, the yarn receiving part carries the yarn package body 7 from the first state to the second state, thereby flipping the yarn package body 7 from a lying position to a standing position. Next, the clamping component of the yarn arranging mechanism 3 is activated, clamping the yarn package body 7, which is now in a standing position. Then, the transport component drives the clamping component to move together with the clamped yarn package body 7, finally transporting and releasing the yarn package body 7 to the preset workstation, completing the pick-and-place and arrangement process of a single yarn package body 7.

[0038] By integrating the yarn bobbin flipping and yarn arrangement functions into one unit, the yarn bobbin posture is flipped by the yarn rotating component, and the subsequent conveying and arrangement are completed by the yarn arrangement mechanism 3. This replaces the complex process of relying on the yarn bobbin's own weight to roll, multiple positioning, and separate lifting in the existing technology. Since the yarn bobbin body 7 can be directly clamped and transferred after flipping without waiting for other auxiliary actions to complete, the entire picking and placing process is more compact, which can effectively shorten the placement and arrangement time of the yarn bobbin body 7, thereby improving the production efficiency of the entire textile production line.

[0039] It should be noted that this embodiment constructs a novel mechanical architecture with a rotatable yarn-turning component and its yarn-bearing part as the core, integrating the functions of flipping and transferring the yarn, and working in coordination with a yarn-laying mechanism 3 that has linear conveying capability. This abandons the complex mechanism of traditional gravity-based rolling positioning and multi-step separation actions. The yarn-turning component directly and actively completes the posture change from lying to standing through a single rotational motion, enabling the flipped yarn bobbin 7 to be directly gripped and conveyed by the yarn-laying mechanism 3.

[0040] In one embodiment, the yarn-turning assembly includes a rotating shaft 2021, which is rotatably mounted on the support member 1 via a rotary support member 203. The yarn-bearing part includes a yarn-receiving member and a yarn-blocking member arranged at an angle. Both the yarn-receiving member and the yarn-blocking member are arranged perpendicular to the rotating shaft 2021. When the yarn-bearing part is in the first state, both the yarn-receiving member and the yarn-blocking member are inclined upwards, and the lying-down yarn body 7 is suitable for receiving between the yarn-receiving member and the yarn-blocking member.

[0041] When the yarn package flipping mechanism 2 needs to receive yarn, the yarn turning assembly is in its initial position. At this time, the yarn receiving component and the yarn blocking component, which are arranged perpendicular to the rotating shaft 2021, are both tilted upwards. After the lying-down yarn package 7 is placed by the external robot arm, the bottom surface of the yarn package 7 rests on the yarn receiving component, and the end face of the yarn package 7 abuts against the yarn blocking component, thus being stably supported between the yarn receiving component and the yarn blocking component. When the first drive assembly 201 drives the rotating shaft 2021 to rotate, the yarn receiving component and the yarn blocking component rotate together with the rotating shaft 2021, thereby causing the yarn package 7 to flip from a lying-down position to a standing position. The yarn receiving component and the yarn blocking component, which are set at an angle, together form a stable support structure, which can effectively limit the position of the yarn package 7 when supporting it, prevent the yarn package 7 from slipping or shifting, ensure the accuracy and consistency of the positioning of the yarn package 7, and ensure that the yarn package 7 can be flipped into place in the subsequent flipping.

[0042] The specific shapes of the yarn receiving and yarn blocking components are not limited to rod-shaped; they can also be plate-shaped, arc-shaped, or other structures that can form a stable contact with the surface of the yarn package body 7. The yarn receiving and yarn blocking components can be arranged at a fixed angle, such as V-shape or L-shape, or their optimal fit can be achieved by adjusting their independent installation angles. The angles and distribution of the yarn receiving and yarn blocking components can be flexibly adjusted according to the specifications, materials, and production requirements of the yarn package body 7.

[0043] Furthermore, the yarn receiving component includes at least two yarn receiving rods 2022, and the yarn blocking component includes at least two yarn blocking rods 2023. In this embodiment, two yarn receiving rods 2022 are arranged in parallel, and two yarn blocking rods 2023 are also arranged in parallel. When receiving the yarn package 7 in a lying position, the weight of the yarn package 7 is shared and supported by the at least two yarn receiving rods 2022, and the axial movement of the yarn package 7 is restricted by the at least two yarn blocking rods 2023. The multiple yarn receiving rods 2022 and yarn blocking rods 2023 are distributed along the length direction of the yarn package 7, realizing line contact or surface contact support and limitation for the yarn package 7.

[0044] The structure of at least two yarn receiving rods 2022 and at least two yarn blocking rods 2023 increases the contact points and support range with the yarn package body 7, making the support more stable and effectively preventing the yarn package body 7 from deflecting, twisting or being damaged locally due to single-point force during the receiving or flipping process, thereby improving the stability and safety of the yarn package body 7 during flipping.

[0045] The number of yarn receiving rods 2022 and yarn blocking rods 2023 can be adaptively increased according to the standard width of the yarn package body 7; for example, three or more rods can be used for longer yarn packages. The cross-sectional shape of the rods is not limited to circular; square, polygonal, or other irregular shapes can also be used to improve contact. Furthermore, the rods can be fixed to the rotating shaft 2021 by welding, bolting, or integrally formed with the rotating shaft 2021.

[0046] In one embodiment, the first drive assembly 201 employs a telescopic drive member capable of outputting linear reciprocating motion. The yarn rotating assembly further includes a yarn rotating rod 2024, one end of which is fixedly connected to the rotating shaft 2021, and the other end is hinged to the drive end of the first drive assembly 201. The yarn rotating rod 2024 is perpendicular to the rotating shaft 2021.

[0047] When the first drive assembly 201 operates as a telescopic drive member, the linear motion of its drive end is transmitted to the yarn-rotating pull rod 2024 through the hinge point. Since one end of the yarn-rotating pull rod 2024 is fixedly connected to and perpendicular to the rotating shaft 2021, when the linear tension or thrust applied by the first drive assembly 201 acts on the free end of the yarn-rotating pull rod 2024, a lever arm is generated acting on the rotating shaft 2021, thereby efficiently converting the linear force or displacement into a torque that drives the rotating shaft 2021 to rotate around its axis. This torque drives the entire yarn-rotating assembly, including the rotating shaft 2021, the yarn receiving component, and the yarn blocking component, to rotate together.

[0048] The linear motion is converted into rotational motion using the yarn-rotating pull rod 2024, which has a simple and reliable structure and high transmission efficiency. The hinged connection between the yarn-rotating pull rod 2024 and the first drive component 201 can adapt to small changes in angle during the motion, reduce motion interference and wear, and ensure the smoothness and reliability of the rotation process of the yarn-rotating component.

[0049] The telescopic drive component is not limited to pneumatic cylinders or hydraulic cylinders; it can also employ linear actuators such as electric push rods and linear motors. The hinge type includes, but is not limited to, ball joints and spherical bearings.

[0050] In this embodiment, the first drive assembly 201 is a linear drive cylinder. The cylinder body of the linear drive cylinder is fixedly mounted on the support member 1 by a mounting bracket or bolts to obtain a stable support reaction foundation. The piston rod end of the linear drive cylinder is hinged to the free end of the yarn-pulling rod 2024 by a pin. The linear drive cylinder is selected from pneumatic cylinders or hydraulic cylinders.

[0051] The cylinder body of the linear drive cylinder is fixedly mounted on the support member 1 to provide supporting reaction force. When the piston rod of the linear drive cylinder extends or retracts, the piston rod pulls or pushes the yarn-rotating pull rod 2024 through the hinge point. The yarn-rotating pull rod 2024 converts the linear motion of the piston rod of the linear drive cylinder into the rotational motion of the rotating shaft 2021, thereby realizing the flipping action of the yarn-rotating assembly. Using a linear drive cylinder as the first drive component 201 is convenient to control, has a fast response speed, and can provide a large driving force, which helps to improve the working efficiency of the entire device.

[0052] In some other embodiments, the first drive component 201 may also be a rotation drive such as a servo motor, and the rotation shaft 2021 may be directly connected to the output shaft of the motor to drive the rotation shaft 2021 to rotate.

[0053] In one embodiment, the clamping assembly includes a pair of opposing yarn clamping arms 302 and at least one second drive assembly 301, the second drive assembly 301 being adapted to drive the pair of yarn clamping arms 302 to move closer to or further away from each other.

[0054] When it is necessary to clamp the yarn package 7 in a standing position, at least one second drive component 301 is activated, driving a pair of oppositely arranged clamping arms 302 to move closer to each other, embracing the yarn package 7 from both sides, thereby clamping the yarn package 7. When it is necessary to release the yarn package 7, the second drive component 301 drives the pair of clamping arms 302 to move away from each other, releasing the yarn package 7.

[0055] The second drive component 301 directly controls the opening and closing of a pair of yarn clamping arms 302, so that the opposing yarn clamping arms 302 can apply force evenly from both sides, ensuring the stability and centering of the clamping, preventing the yarn bobbin body 7 from tilting or falling over during the clamping process, and ensuring the reliability of the subsequent transportation process.

[0056] Furthermore, to increase the stability of clamping, a clamping plate 303 is provided at the upper end of each clamping arm 302, with the opposite sides of the pair of clamping plates 303 being concave. When the pair of clamping arms 302 are driven closer to each other by the second driving component 301, the pair of clamping plates 303 at the ends of the clamping arms 302 approach from both sides of the yarn package 7. Since the opposite sides of the pair of clamping plates 303 are concave, the concave curved surface can better conform to the cylindrical outer contour of the standing yarn package 7, achieving a wrapping clamping of the yarn package 7. The clamping plate 303 can be a concave arc or a concave folded plate. In this embodiment, in order to adapt to yarn packages 7 with different outer diameters, the clamping plate 303 adopts a folded plate. The clamping plate 303 includes a central fixed plate and a pair of side plates fixed on both sides of the fixed plate, with the pair of side plates arranged in a figure-eight shape.

[0057] The concave clamping plate 303 increases the contact area with the outer wall of the yarn package 7, making the clamping force distribution more uniform and avoiding surface damage to the yarn package 7 that may be caused by point or line contact. At the same time, the concave curved surface structure helps to position the yarn package 7 during clamping, further improving the stability of clamping and preventing the yarn package 7 from slipping off.

[0058] In one embodiment, the conveying component includes a slide rail pair 307, a third drive component 306, and a sliding platform 304. The sliding platform 304 is slidably mounted on the slide rail pair 307, and the third drive component 306 drives the sliding platform 304 to slide along the slide rail pair 307. A clamping component is mounted on the sliding platform 304. The slide rail pair 307 includes a guide rail and a slider, and the sliding platform 304 slides on the slide rail under the action of the slider.

[0059] The sliding platform 304 is mounted on the support member 1 via the slide rail pair 307 and can slide along the direction defined by the slide rail pair 307. The clamping assembly is fixedly mounted on the sliding platform 304. When the clamping assembly successfully clamps the standing yarn bobbin 7 at the yarn bobbin turning station, the third drive assembly 306 starts to work. The third drive assembly 306 outputs power and drives the sliding platform 304 to move along the guide direction of the slide rail pair 307 through the transmission mechanism. Since the clamping assembly is mounted entirely on the sliding platform 304, the movement of the sliding platform 304 directly drives the clamping assembly and the yarn bobbin 7 firmly clamped by it to smoothly leave the station above the yarn bobbin turning mechanism 2, move along the preset straight path, and finally reach the front of the set arrangement station. The support member 1 is provided with a placement platform 4, which is located directly above the slide rail pair 307, but the top surface of the placement platform 4 is lower than the bottom height of the yarn bobbin 7 when the yarn receiving part is in the second state. After the yarn package 7 moves into position under the drive of the sliding platform 304, the yarn clamping arm 302 opens, causing the yarn package 7 to fall to the corresponding position on the sliding platform 304.

[0060] The slide rail pair 307 can be a linear guide or an optical shaft sleeve, etc. The third drive component 306 can be a servo motor, a stepper motor, or a linear motor. The third drive component 306 and the sliding platform 304 are directly driven, such as by a linear motor, or indirectly driven by a synchronous belt 305 or a lead screw, etc.

[0061] In this embodiment, a timing belt 305 is mounted around both ends of the slide rail pair 307. The timing belt 305 is typically tensioned by two or more pulleys to form a closed loop. The sliding platform 304 is fixedly mounted on the timing belt 305. At least one end of the timing belt 305 is mounted around the drive end of the third drive assembly 306. The third drive assembly 306 drives the timing belt 305 to reciprocate so as to carry the sliding platform 304 to slide along the slide rail pair 307.

[0062] The sliding platform 304 is fixedly mounted on the synchronous belt 305 wound around the slide rail pair 307. When the third drive assembly 306 is running, its drive end drives the synchronous belt 305 to perform cyclic reciprocating motion. Since the sliding platform 304 is fixedly connected to the synchronous belt 305, the motion of the synchronous belt 305 is directly converted into the reciprocating linear motion of the sliding platform 304 along the slide rail pair 307. This facilitates long-distance conveying of the sliding platform 304, ensures the accuracy of transporting the yarn package 7 to the preset work position, and improves the reliability of the entire device in arranging the yarn package 7.

[0063] Secondly, this utility model also provides a textile production line having the yarn loading and unloading device described in this application. It also includes a yarn-picking robot 5 and a stacking robot 6.

[0064] When the yarn package loading and unloading device is working, for stability, the yarn package body 7 is in a lying position on the cage of the yarn package conveyor line, such as... Figure 5 As shown. The yarn-picking robot 5 lifts the yarn bobbin body 7 from the conveyor line using its lifting gripper. Once the conveyor cage continues to move forward until the yarn bobbin body 7 can descend without interference, the yarn-picking robot 5 descends until the highest point of the yarn bobbin is lower than the lowest point of the cage. Then, the yarn-picking robot 5 flips, causing the yarn bobbin body 7 to rotate above the yarn-rotating component 202. The yarn-receiving rod 2022 of the yarn-rotating component 202 is in an upward-tilted state, as shown. Figure 6 As shown, the yarn-picking robot 5 continues to move downwards to below the yarn-rotating component 202, and the yarn cone body 7 sits on the yarn-receiving rod 2022 of the yarn-rotating component 202. The yarn cone body 7 then becomes a semi-reclined state, as shown. Figure 7 As shown, the yarn package 7 moves downward along the yarn receiving rod 2022 under the action of gravity until the bottom surface of the yarn package touches the yarn blocking rod 2023. At the same time, the yarn picking robot 5 rotates to the yarn picking position. Figure 8 As shown, the yarn-picking robot arm 5 moves upward to prepare for the next yarn picking, while the yarn-rotating cylinder, which is the first drive component 201, retracts to pull the yarn-rotating lever 2024, causing the yarn-rotating component 202 to rotate. The yarn package body 7 rotates from a semi-reclined state to a standing state, and the flipping action of the yarn package body 7 is completed. Figure 9 As shown. The yarn clamping cylinder retracts, and the yarn clamping arm 302 clamps the yarn bobbin body 7. Then, the servo motor, which is the second drive component 301, drags the sliding platform 304 forward, placing the yarn bobbins 7 one by one into the set positions from far to near, as shown. Figure 10 and Figure 11 As shown, after the yarn bobbin 7 is removed from the yarn rotating component 202, the yarn rotating cylinder extends and pushes the yarn rotating lever 2024 to rotate to the yarn receiving position, waiting for the next yarn bobbin 7 to arrive. Figure 12 As shown. After the yarn feeding mechanism 3 places the yarn bobbin body 7 onto the placing platform 4, it releases the yarn bobbin body 7 and returns it to the starting position, waiting for the next yarn bobbin body 7 to rotate to the upright position, as shown. Figure 13 As shown. Since the yarn bobbin body 7 has already been lifted during yarn turning, it does not need to be lifted again during yarn clamping. Simply placing the platform of the yarn bobbin body 7 below the yarn guide bar 2023 by a certain distance is sufficient to prevent wear on the yarn bobbin body 7. After the entire row of yarn bobbin bodies 7 is arranged, the stacking robot 6 removes the arranged yarn bobs and stacks them, as shown. Figure 14 As shown, the yarn-picking robot 5 descends below the yarn rotating frame, places the yarn cone on the frame, and then rotates back to the yarn-picking position without waiting, reducing yarn-picking time and improving work efficiency.

[0065] By integrating the yarn bobbin flipping and yarn arrangement functions into one unit, the yarn bobbin posture is flipped by the yarn rotating component, and the subsequent conveying and arrangement are completed by the yarn arrangement mechanism 3. This replaces the complex process of relying on the yarn bobbin's own weight to roll, multiple positioning, and separate lifting in the existing technology. Since the yarn bobbin body 7 can be directly clamped and transferred after flipping without waiting for other auxiliary actions to complete, the entire picking and placing process is more compact, which can effectively shorten the placement and arrangement time of the yarn bobbin body 7, thereby improving the production efficiency of the entire textile production line.

[0066] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
