Description

Technical Field

[0001] This invention relates to the field of yarn doffing mechanisms, and in particular to a yarn doffing mechanism for spandex yarn cakes. Background Technology

[0002] Spandex yarn cakes are wound in two ways during production: clockwise winding and counterclockwise winding. After production, the two winding methods of spandex yarn cakes are stacked in sequence. When transferring them to the next process, the winding direction of the spandex yarn cakes needs to be unified. Currently, this is done manually, but manual turning is labor-intensive, prone to errors, and can lead to production disruptions and reduced efficiency. Summary of the Invention

[0003] The technical problem to be solved by this invention is: in order to solve the problem that the existing manual flipping is labor-intensive, prone to flipping errors, and thus unable to carry out normal production and affect production efficiency, a spandex filament cake doffing mechanism is provided.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a spandex filament cake doffing mechanism, including a frame, and further including a flipping mechanism and a conveying mechanism disposed on the frame. The conveying mechanism is used to convey a mold base carrying the spandex filament cake, and the flipping mechanism is used to clamp and flip the spandex filament cake that needs to be flipped and place it on the mold base, thereby realizing the uniform winding direction of the spandex filament cake on the mold base.

[0005] This invention uses a flipping mechanism on the frame to flip and adjust the spandex yarn cakes that need to be flipped, thereby achieving a unified winding direction of the spandex yarn cakes. The flipped yarn cakes are then output together via a conveying mechanism, reducing the labor intensity of workers, greatly reducing the flipping error rate, ensuring stable and reliable production, and improving production efficiency.

[0006] To achieve the flipping mechanism, the flipping mechanism further includes a rotating mechanism and a clamping mechanism disposed on the rotating mechanism. The clamping mechanism includes at least two grippers. The rotating mechanism is provided with a function to control the grippers to move closer to or further away from the first driving mechanism, thereby clamping or releasing the spandex yarn cake. By rotating the clamping mechanism, the spandex yarn cake is flipped to the desired state.

[0007] To further realize the rotating mechanism, the rotating mechanism includes a rotating shaft rotatably mounted on a frame, and a second drive mechanism is provided on the frame. The output end of the second drive mechanism is connected to the rotating shaft for mutual transmission. The second drive mechanism on the frame drives the rotating shaft to rotate on the frame, thereby driving the clamping mechanism on the rotating shaft to rotate.

[0008] To facilitate the placement of the spandex yarn cake on the clamping mechanism onto the mold base, the rotating mechanism is further equipped with a control mechanism for controlling the clamping mechanism to move closer to or away from the mold base. The control mechanism includes a connecting plate and a third driving mechanism. The connecting plate is slidably mounted on the rotating mechanism, and the third driving mechanism is mounted on the rotating mechanism with its extended end mounted on the connecting plate. The clamping mechanism is also mounted on the connecting plate. By controlling the clamping mechanism to move closer to or away from the mold base—that is, by the third driving mechanism causing the connecting plate to shift on the rotating mechanism—the spandex yarn cake on the clamping mechanism is moved closer to or away from the mold base, facilitating its placement onto the mold base.

[0009] To enable the connecting plate to slide on the rotating mechanism, a guide shaft is further provided on the connecting plate, and a guide sleeve matching the guide shaft is provided on the rotating mechanism, with one end of the guide shaft passing through the guide sleeve. The sliding of the connecting plate on the rotating mechanism is achieved through the cooperation of the guide shaft on the connecting plate and the guide sleeve on the rotating mechanism.

[0010] To facilitate the placement of the spandex yarn cake onto the mold base, the conveying mechanism further includes several rollers rotatably mounted on the frame along the conveying direction of the mold base. The conveying mechanism includes a fixed section and a lifting section. The frame is equipped with a lifting mechanism for controlling the lifting section to move closer to or further away from the tilting mechanism. By configuring the conveying mechanism into a fixed section and a lifting section, the lifting mechanism controls the lifting section to rise or fall. When rising, it moves closer to the clamping mechanism, simultaneously aligning the spandex yarn cake on the clamping mechanism with the mold base on the lifting section, facilitating the clamping mechanism to place the spandex yarn cake onto the mold base.

[0011] To further implement the lifting mechanism, the lifting mechanism includes a fourth drive mechanism mounted on the frame. The extended end of the fourth drive mechanism is mounted on the lifting section, which is slidably mounted on the frame along its displacement direction. The lifting mechanism is achieved by driving the lifting section to rise or fall using the fourth drive mechanism.

[0012] To enable the lifting section to slide on the frame, a sliding shaft is further provided on the lifting section, and a sliding hole matching the sliding shaft is provided on the frame. The sliding shaft is slidably disposed within the slider. The sliding section slides on the frame by engaging with the sliding shaft on the lifting section and the sliding hole on the frame.

[0013] To further improve production efficiency, the conveying mechanism includes at least two parallel forward conveying channels and a reverse flipping channel. The lifting section is located on the reverse flipping channel, and the flipping mechanism is used to clamp, flip, and place the spandex yarn cake onto the mold base of the reverse flipping channel. By setting forward conveying channels and reverse flipping channels on the frame, that is, placing the spandex yarn cake to be flipped on the forward conveying channel and the spandex yarn cake to be flipped on the reverse flipping channel, the flipping of the spandex yarn cake is not affected, nor is the conveying of the spandex yarn cake affected, thus improving production efficiency.

[0014] To better ensure the spandex yarn cake is placed on the mold base, the frame is further equipped with a positioning mechanism for aligning the mold base with the flipping mechanism. The positioning mechanism includes a positioning plate, with the mold base located between the positioning block and the frame. The positioning block has a V-shaped groove corresponding to the mold base. The frame is equipped with a fifth driving mechanism for controlling the positioning block to move closer to or further away from the mold base, thus enabling the mold base to abut against or disengage from the V-shaped groove. The fifth driving mechanism drives the positioning block, and the V-shaped groove on the positioning block positions the mold base, ensuring the spandex yarn cake on the clamping mechanism is placed on the mold base.

[0015] The beneficial effects of this invention are as follows: When the spandex yarn cake doffing mechanism of this invention is in use, a flipping mechanism is set on the frame to flip and adjust the spandex yarn cake that needs to be flipped, thereby achieving a unified winding direction of the spandex yarn cake. The flipped yarn cake is then output together by a conveying mechanism, which reduces the labor intensity of the workers, greatly reduces the flipping error rate, ensures stable and reliable production, improves production efficiency, and avoids the problems of existing manual flipping, which involves a large workload, is prone to flipping errors, and leads to production disruptions and reduced production efficiency.

[0032] like Figure 1-6 As shown, a spandex filament feeding mechanism includes a frame 1, a flipping mechanism 3 and a conveying mechanism 2 disposed on the frame 1. The conveying mechanism 2 is used to convey a mold base 4 that carries the spandex filaments. The flipping mechanism 3 is used to clamp and flip the spandex filaments that need to be flipped and place them on the mold base 4, thereby achieving a uniform winding direction of the spandex filaments on the mold base 4.

[0033] The flipping mechanism 3 includes a rotating mechanism 302 and a clamping mechanism 301 disposed on the rotating mechanism 302. The clamping mechanism 301 includes two grippers 3011. The rotating mechanism 302 is provided with a mechanism for controlling the grippers 3011 to move closer to or further away from the first driving mechanism 3012, thereby clamping or releasing the spandex yarn cake.

[0034] The rotating mechanism 302 includes a rotating shaft 3021 rotatably mounted on the frame 1. A second driving mechanism 3022 is provided on the frame 1, and the output end of the second driving mechanism 3022 is connected to the rotating shaft 3021 for mutual transmission.

[0035] The rotating mechanism 302 is provided with a control mechanism 303 for controlling the clamping mechanism 301 to move closer to or further away from the mold base 4. The control mechanism 303 includes a connecting plate 3031 and a third driving mechanism 3032. The connecting plate 3031 is slidably disposed on the rotating mechanism 302. The third driving mechanism 3032 is disposed on the rotating mechanism 302. The protruding end of the third driving mechanism 3032 is disposed on the connecting plate 3031. The clamping mechanism 301 is disposed on the connecting plate 3031.

[0036] The connecting plate 3031 is provided with a guide shaft, and the rotating mechanism 302 is provided with a guide sleeve that matches the guide shaft. One end of the guide shaft passes through the guide sleeve.

[0037] The conveying mechanism 2 includes several rollers rotatably mounted on the frame 1 along the conveying direction of the mold base 4. The conveying mechanism 2 includes a fixed section 2021 and a lifting section 2022. The frame 1 is provided with a lifting mechanism 203 for controlling the lifting section 2022 to move closer to or away from the tilting mechanism 3. Here, the fixed section 2021 is a roller directly rotatably mounted on the frame 1, while the lifting section 2022 is a conveying mechanism 2 detached from the frame 1. This conveying mechanism 2 includes a frame and a rotating shaft 3021 rotatably mounted on the frame. When lifting is required, the lifting mechanism 203 drives the frame to rise and move closer to the tilting mechanism 3. When lowering is required, the lifting mechanism 203 drives the frame to fall until the rollers on the frame are flush with the rollers on the frame 1.

[0038] The lifting mechanism 203 includes a fourth drive mechanism mounted on the frame 1. The extended end of the fourth drive mechanism is mounted on the lifting section 2022, and the lifting section 2022 is slidably mounted on the frame 1 along its displacement direction.

[0039] The lifting section 2022 is provided with a sliding shaft, and the frame 1 is provided with a sliding hole that matches the sliding shaft. The sliding shaft is slidably disposed in the slider.

[0040] The conveying mechanism 2 includes at least two parallel forward conveying channels 201 and reverse flipping channels 202. The lifting section 2022 is arranged on the reverse flipping channel 202. The flipping mechanism 3 is used to clamp and flip the spandex yarn cake and place it on the mold base 4 of the reverse flipping channel 202.

[0041] The frame 1 is equipped with a positioning mechanism 5 for aligning the mold base 4 with the flipping mechanism 3. The positioning mechanism 5 includes a positioning plate. The mold base 4 is located between the positioning block 501 and the frame 1. The positioning block 501 has a V-shaped groove 5011 corresponding to the mold base 4. The frame 1 is equipped with a fifth drive mechanism 502 for controlling the positioning block 501 to move closer to or further away from the mold base 4, and realizing that the mold base 4 abuts against or disengages from the V-shaped groove 5011. Here, the first drive mechanism 3012, the third drive mechanism 3032, the fourth drive mechanism, and the fifth drive mechanism 502 are all cylinders or electric push rods or other components that can control the movement of their corresponding parts. The second drive mechanism 3022 is a servo motor, which is connected to the rotating shaft 3021 through a coupling.

[0042] In the initial state of the aforementioned spandex filament cake doffing mechanism, the gripper 3011 of the clamping mechanism 301 is in an upward state, while the fixed section 2021 and the lifting section 2022 of the conveying mechanism 2 are in a level state with each other, and the positioning block 501 of the positioning mechanism 5 is in a state of being detached from the mold base 4.

[0043] When the mold base 4 is being transported and positioned, the mold base 4 is placed on the conveying mechanism 2. The conveying mechanism 2 transports a portion of the mold base 4 to the forward conveying channel 201 and another portion of the mold base 4 to the reverse flipping channel 202. The cylinders at the fifth drive mechanism 502 of the positioning mechanism 5 on the forward conveying channel 201 and the reverse flipping channel 202 drive the positioning block 501 to move towards the mold base 4 until the V-groove 5011 on the positioning block 501 contacts the mold base 4 and abuts the mold base 4 against the frame 1, thereby achieving the positioning of the mold base 4.

[0044] Then, during the flipping process, since one set of spandex yarn cakes needs to be flipped while the other set does not, the external robotic arm places the spandex yarn cakes that need to be flipped above the gripper 3011 of the clamping mechanism 301. At this time, the cylinder of the second drive mechanism 3022 at the control mechanism 303 drives the clamping mechanism 301 on the connecting plate 3031 to gradually move closer to the spandex yarn cake on the external robotic arm until the clamping mechanism 301 moves to the required position. The cylinder at the first drive mechanism 3012 on the clamping mechanism 301 drives the gripper 3011 to move relatively closer and clamp the spandex yarn cake. Alternatively, the cylinder at the first drive mechanism 3012 can be controlled to move the gripper 3011 relatively away. Since there is a paper tube in the middle of the spandex yarn cake, the two grippers 3011 open and support on the two side walls of the paper tube. The external robotic arm releases the spandex yarn cake.

[0045] Then, the servo motor at the second drive mechanism 3022 on the rotating mechanism 302 drives the rotating shaft 3021 to rotate 180°. The rotating shaft 3021 drives the clamping mechanism 301 on the control mechanism 303 to rotate together, which makes the gripper 3011 of the clamping mechanism 301 change from facing upward to facing downward, and align the spandex yarn cake on the gripper 3011 with the mold base 4 on the lower lifting section. The cylinder at the fifth drive mechanism 502 of the lifting mechanism 203 drives the lifting section 2022 on the conveying mechanism 2 to rise, so that the positioned mold base 4 rises together. After the spandex yarn cake is placed on the mold base 4, the first drive mechanism 301 on the clamping mechanism 301... The cylinder at the drive mechanism 3012 drives the gripper 3011 to loosen the spandex filament cake. At the same time, the cylinder at the fifth drive mechanism 502 on the lifting mechanism 203 drives the lifting section to descend, aligning the fixed section 2021 and the lifting section 2022. Then, the servo motor at the second drive mechanism 3022 of the rotating mechanism 302 drives the rotating shaft 3021 to rotate, which causes the clamping mechanism 301 and the control mechanism 303 to return to their initial positions, completing the flipping of the spandex filament cake. At this time, the spandex filament cakes on the forward conveyor 201 and the reverse flipping conveyor 202 are aligned. Finally, the spandex filament cake is output through the conveying mechanism 2. The above steps can be repeated.

[0046] The above description, based on the preferred embodiments of the present invention, provides inspiration. Those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification but must be determined according to the claims.
