Description

Technical Field

[0001] The present invention belongs to the technical field of textile equipment, and particularly relates to a bobbin conveying device for feeding a circular loom. Background Art

[0002] A circular loom (also called a circular knitting machine) is a mechanical device used for producing knitted fabrics. It weaves in a circular structure through an annular needle cylinder and needle positions. Circular looms can produce various types of knitted fabrics, such as T-shirt fabrics, underwear, socks, sportswear fabrics, etc. Different from flat looms, circular looms can achieve more efficient continuous weaving, so they are widely used in the textile industry. When feeding a circular loom, the yarn on the bobbin (spool) is correctly installed on the circular loom to ensure that the machine can operate normally and produce fabrics smoothly.

[0003] In the prior art, the feeding method of circular looms mostly uses a manipulator to control a fixture to take out the used bobbin from the bobbin rack, then put the used bobbin into a recycling bin, and move it to the top of the material table. After clamping the new bobbin, it is installed on the surface of the bobbin rack again. The manipulator needs to move back and forth several times to complete the replacement operation, which is very inconvenient to use. Moreover, after the bobbin is installed on the surface of the bobbin rack, it is necessary to manually install a buckle in front of the bobbin to prevent the bobbin from falling off, which greatly reduces the feeding efficiency of the circular loom.

[0004] Therefore, we provide a bobbin conveying device for feeding a circular loom to solve the above problems. Summary of the Invention

Through the cooperation of a clamping assembly, an adjusting assembly, and a limiting assembly, the problem that the feeding method of the circular loom in the prior art requires the manipulator to move back and forth several times to complete the replacement operation and is very inconvenient to use is solved.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions.

[0007] The present invention relates to a bobbin conveying device for feeding a circular loom, which includes a bobbin rack. An installation rod is installed on the front side of the bobbin rack. A cylindrical shell is sleeved on the surface of the installation rod. A robotic arm is arranged on one side of the bobbin rack; a clamping assembly is arranged on one side of the bobbin rack. The clamping assembly includes a driving box, which is installed at the output end of the robotic arm. An adjusting shell is arranged on one side of the driving box. A clamping plate is arranged on one side of the adjusting shell. Moving plates are fixedly connected to both the top and bottom of the clamping plate. A visual detection probe is installed on one side of the moving plate. The two cylindrical shells are respectively fixed by the clamping assembly at the same time; an adjusting assembly is arranged on one side of the robotic arm. The adjusting assembly includes a driving motor, which is installed inside the driving box. The output end of the driving motor is fixedly connected to a driving rod. The other end of the driving rod penetrates through the driving box and is fixedly connected to a rotating seat. The positions of the two cylindrical shells are exchanged by the adjusting assembly; a limiting assembly is arranged inside the installation rod. The limiting assembly includes a contraction groove, which is respectively opened at the top and bottom of the installation rod. A limiting block is arranged inside the contraction groove. The cylindrical shell is limited by the limiting assembly.

[0008] The present invention is further configured such that the clamping assembly further includes a servo motor. The output end of the servo motor is fixedly connected to a worm. A worm gear is meshed on one side of the worm. A screw rod is fixedly connected to the center of the worm gear.

[0009] The present invention is further configured such that moving sleeves are threadedly connected to both the top and bottom of the screw rod. A moving rod is fixedly connected to one side of the moving sleeve. The other end of the moving rod penetrates through the adjusting shell and is fixedly connected to the moving plate.

[0010] The present invention is further configured such that both the top and bottom of the screw rod are movably connected to the inner wall of the adjusting shell through bearings. The threads on the top and bottom of the screw rod are opposite.

[0011] The present invention is further configured such that the limiting assembly further includes a reset cylinder, which is respectively fixedly connected to the front side and the rear side of the adjusting shell. A cross plate is fixedly connected inside the installation rod. A telescopic tube is fixedly connected inside the limiting block. A support rod is slidably connected inside the telescopic tube.

[0012] The present invention is further configured such that the other end of the support rod penetrates through the telescopic tube and is fixedly connected to the cross plate. The limiting block is slidably connected to the inner wall of the contraction groove.

[0013] The present invention is further configured such that a spring is sleeved on the surface of the support rod. One end of the spring is fixedly connected to the cross plate.

[0014] The present invention is further configured such that a base is fixedly connected to the bottom of the robotic arm. A placement table is arranged on one side of the base.

[0017] The present invention has the following beneficial effects.

[0018] 1. Through the setting of the clamping assembly, when the clamping plate is driven by the robotic arm to move, one set of clamping plates can clamp the raw material cylinder shell, and at the same time, the other set of clamping plates can pick up the used cylinder shell. When the robotic arm drives the clamping plate to move between the wire rack and the raw material rack, the simultaneous picking and placing of multiple sets of cylinder shells can be realized, effectively improving the feeding efficiency of the circular loom.

[0019] 2. Through the setting of the adjusting assembly, after one set of clamping plates clamp the used cylinder shell and remove the mounting rod, under the action of the driving motor, the adjusting shell can be driven to rotate, exchanging the positions of the two sets of clamping plates, rotating the cylinder shell downward, and aligning the new cylinder shell with the mounting rod, greatly improving the replacement efficiency of the cylinder shell.

[0020] 3. Through the setting of the limiting assembly, when the cylinder shell is installed on the surface of the mounting rod, the limiting block can be used to limit the cylinder shell, preventing the cylinder shell from detaching from the mounting rod, playing a role in quick fixation. At the same time, when removing the cylinder shell, the reset cylinder can be moved to the surface of the mounting rod, and the limiting block can be pushed into the mounting rod to cancel the limitation of the reset cylinder, enabling quick disassembly and assembly of the cylinder shell.

[0021] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

[0033] Embodiment 1

[0034] Please refer to Figures 1-8, the present invention is a bobbin conveying device for feeding a circular loom, which includes a wire rack 1.

A clamping plate 7 is arranged on one side of the adjusting shell 6. Moving plates 8 are fixedly connected to both the top and bottom of the clamping plate 7. A visual detection probe 9 is installed on one side of the moving plate 8. The two cylinder shells 3 are respectively fixed by the clamping assembly at the same time; an adjusting assembly is arranged on one side of the robotic arm 4. The adjusting assembly includes a driving motor 10. The driving motor 10 is installed inside the driving box 5. The output end of the driving motor 10 is fixedly connected to a driving rod 11. The other end of the driving rod 11 penetrates through the driving box 5 and is fixedly connected to a rotating seat 12. The positions of the two cylinder shells 3 are exchanged by the adjusting assembly; a limiting assembly is arranged inside the installation rod 2. The limiting assembly includes a contraction groove 13. The contraction grooves 13 are respectively opened at the top and bottom of the installation rod 2. A limiting block 14 is arranged inside the contraction groove 13. The cylinder shell 3 is limited by the limiting assembly.

[0035] Specifically: The working principle of the robotic arm 4 is based on electric drive, hydraulic and pneumatic systems. It realizes various movements through a chain structure composed of multiple joints and connecting rods. The core part includes a control system, sensors, actuators and motors. The control system is responsible for receiving instructions and calculating the movement trajectory, and then controls each actuator (such as a motor or a pneumatic device) through a driving signal to drive each joint of the robotic arm 4 and the driving box 5 to move. At the same time, the visual detection probe 9 is used to capture the position of the cylinder shell 3 for determining the material taking position. The sensors are used to monitor parameters such as position, force, and temperature, and feedback them to the control system in real time to ensure precise operation and safety, and can complete the conveying of the cylinder shell 3.

[0036] Embodiment Two

[0037] Please refer to Figures 1-8, on the basis of the first embodiment, the clamping assembly further includes a servo motor 15. The output end of the servo motor 15 is fixedly connected with a worm 16. One side of the worm 16 is engaged with a worm gear 17. The center of the worm gear 17 is fixedly connected with a screw rod 18. Both the top and bottom of the surface of the screw rod 18 are threadedly connected with moving sleeves 19. One side of the moving sleeve 19 is fixedly connected with a moving rod 20. The other end of the moving rod 20 penetrates through the adjusting shell 6 and is fixedly connected with the moving plate 8. Both the top and bottom of the screw rod 18 are movably connected with the inner wall of the adjusting shell 6 through bearings. The threads on the top and bottom of the surface of the screw rod 18 are opposite. The limiting assembly further includes a reset cylinder 21. The reset cylinder 21 is fixedly connected to the front side and the rear side of the adjusting shell 6 respectively. A cross plate 22 is fixedly connected inside the mounting rod 2. A telescopic tube 23 is fixedly connected inside the limiting block 14. A support rod 24 is slidably connected inside the telescopic tube 23. The other end of the support rod 24 penetrates through the telescopic tube 23 and is fixedly connected with the cross plate 22. The limiting block 14 is slidably connected with the inner wall of the contraction groove 13.

[0038] Specifically: The mounting rod 2 is fixed on the surface of the wire rack 1 for storing the barrel shell 3. The driving motor 10 can drive the rotating seat 12 to rotate, which is convenient for adjusting the positions of the two driving boxes 5. When the worm gear 17 is engaged with the worm 16, it can prevent the screw rod 18 from rotating automatically, playing a role of self-locking. The threads on the top and bottom of the surface of the screw rod 18 are opposite, which can drive the two moving sleeves 19 to move relatively and in opposite directions when the screw rod 18 rotates.

[0039] Embodiment Three

[0040] Please refer to Figures 1-8 , on the basis of the first embodiment, a spring 25 is sleeved on the surface of the support rod 24. One end of the spring 25 is fixedly connected with the cross plate 22. The bottom of the robotic arm 4 is fixedly connected with a base 26. A placement table 27 is arranged on one side of the base 26. A raw material rack 28 is arranged on the top of the placement table 27. A collection box 29 is arranged on the top of the placement table 27. One side of the clamping plate 7 is fixedly connected with a rubber pad 30. One side of the rotating seat 12 is fixedly connected with the adjusting shell 6.

[0041] Specifically: The inner diameter of the reset cylinder 21 is larger than the diameter of the mounting rod 2, which can push the limiting block 14 when the reset cylinder 21 moves to the surface of the mounting rod 2. The telescopic tube 23 slides on the surface of the support rod 24, which can support the up and down movement of the limiting block 14. The spring 25 has the function of compressing and storing energy, which can reset the limiting block 14. The raw material rack 28 is used for storing the unused barrel shells 3. The collection box 29 can store the used barrel shells 3. The rubber pad 30 can buffer the clamping pressure between the clamping plate 7 and the barrel shell 3.

[0042] The working principle of the present invention is as follows: When it is necessary to remove the bobbin case 3 that has used up the wire, the staff drives the robotic arm 4 through an external controller, drives the driving box 5 and the clamping plate 7 to move through the robotic arm 4, and uses the vision detection probe 9 to capture the position of the bobbin case 3 for determining the material taking position, so that the clamping plate 7 moves to the surface of the bobbin case 3. While the robotic arm 4 drives the driving box 5 to move, it can also drive the reset cylinder 21 to move. When the reset cylinder 21 moves to the surface of the mounting rod 2, the wall of the reset cylinder 21 can be used to squeeze the limit block 14 and push the limit block 14 back into the mounting rod 2 to cancel the limit on the bobbin case 3.

[0043] After that, the servo motor 15 is started. The servo motor 15 drives the worm gear 16 to drive the worm wheel 17 to rotate. The worm wheel 17 drives the screw rod 18 to drive the two moving sleeves 19 to move relatively. The moving sleeves 19 drive the clamping plate 7 to move in cooperation with the moving rod 20 and the moving plate 8. When the two clamping plates 7 move relatively, they can clamp the bobbin case 3, and then the robotic arm 4 drives the clamping plate 7 and the bobbin case 3 to separate from the mounting rod 2 to complete the rapid disassembly.

[0044] After that, the driving motor 10 is started. The driving motor 10 drives the rotating seat 12 to rotate through the driving rod 11. The rotating seat 12 drives the two driving boxes 5 to rotate 180 degrees to exchange the positions of the two clamping plates 7, so that the new bobbin case 3 is aligned with the mounting rod 2. Then, the robotic arm 4 is controlled again to drive the bobbin case 3 to be sleeved on the surface of the mounting rod 2, and the rapid installation can be completed, which can effectively improve the feeding efficiency of the circular loom.
