[0025] The present invention discloses an equi-spaced conveying type yarn sorting and yarn head finding device. An implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings.

[0026] Combination Figure 1 and Figure 2 As shown, the yarn head finding device includes a frame 1, a conveying assembly and a yarn suction head assembly, and the conveying assembly is arranged on the frame 1. The conveying assembly includes a rotating motor 7, two chains 2, a plurality of bobbin shafts 5 and four guide shafts 4, each of which is rotatably connected to the frame 1 through a bearing, and each guide shaft 4 is arranged approximately in a rectangular shape. Gears are fixed on both sides of each guide shaft 4, and the two chains 2 are respectively meshed with the gears on the same side of the guide shaft 4. A motor is fixed on the frame 1, and the motor is connected to a guide pump transmission to drive the two chains 2 to move. A bobbin roller 6 is provided at the bottom of the bobbin shaft 5, and a fixed frame 3 is rotatably connected between the bobbin shaft 5 and the bobbin roller 6, and the connection is located in the middle position of the fixed frame 3, and the two ends of the fixed frame 3 are respectively fixedly connected to the two ends located on both sides of the bobbin shaft 5. The bobbin 20 is suitably arranged on the bobbin shaft 5.

[0027] The rotating motor 7 is connected to the frame 1 through an adjusting part, and the adjusting part includes a spring bracket 9, a connecting plate 8 and two sliding rods. The spring bracket 9 is fixedly connected to the frame 1, and the two sliding rods are fixed on the spring bracket 9. The connecting plate 8 is matched with the two sliding rods through a through hole and moves along the two sliding rods. A spring is sleeved on the sliding rod, and the spring is located between the spring bracket 9 and the connecting plate 8. The outer ends of the two sliding rods are threaded with nuts to prevent the connecting plate 8 from detaching from the sliding rod. The rotating motor 7 is fixedly connected to the connecting plate 8 and is located between the two sliding rods.

[0028] Combination Figure 3 and Figure 4 As shown, the yarn suction head assembly is arranged on one side of the frame 1, and the yarn suction head assembly includes a first cylinder 12, a second cylinder 14, a cylinder bracket 13, a slide rail 18, a slider 19, a yarn suction head mouth 16, a positioning plate 15 and a fan. One side of the frame 1 protrudes outward to form an extension plate 11, and the slide rail 18 is arranged in a direction perpendicular to the moving direction of the bobbin yarn 20, and is fixedly connected to the top of the extension plate 11. The slider 19 is arranged on the slide rail 18, and the cylinder bracket 13 is fixedly connected to the top of the slider 19. One end of the first cylinder 12 is fixedly connected to the extension plate 11, and the other end is fixedly connected to the bottom of the cylinder bracket 13. The first cylinder 12 drives the slider 19 to move along the slide rail 18. One end of the second cylinder 14 is fixedly connected to the cylinder bracket 13, and the other end is fixedly connected to the lower side wall of the positioning plate 15. Combined with Figure 5 , Figure 6 as well as Figure 7 As shown, the cross section of the positioning plate 15 is approximately C-shaped, and the yarn suction nozzle 16 is located in the positioning plate 15. The inner wall of the yarn suction nozzle 16 is funnel-shaped, and the lowest point is located in the middle of the inner wall, and is connected to a connecting pipe 17. Figure 8 and Fig. 9 As shown, the inner side wall of the funnel-shaped yarn suction head mouth 16 facilitates the yarn head to smoothly enter the connecting tube 17. The upper part of the positioning plate 15 has a notch, and the connecting tube 17 passes through the notch and is fixedly connected to the cylinder bracket 13. The cross-section of the yarn suction head mouth 16 is approximately pentagonal, and a yarn suction port 21 is provided at the vertical edge line of the outer side of the yarn suction head mouth 16. The yarn suction port 21 is inclined to match the outer contour of the tube yarn 20. The fan is connected to the connecting tube 17 through a hose, and the fan is used to drive the airflow to move in a directional manner and generate negative pressure to absorb the yarn head. The yarn suction head assembly also includes a controller, a pressure sensor and a photoelectric sensor. The controller is connected to the pressure sensor and the photoelectric sensor respectively. The pressure sensor is arranged at a position on the positioning plate 15 where it can contact the tube yarn 20, and the photoelectric sensor is arranged in the connecting tube 17.

[0029] During operation, the existing turning manipulator sets the bobbin 20 on the bobbin shaft 5, and the motor provides power to drive the bobbin 20 to move. The rotating motor 7 is adjacent to the yarn suction head assembly, and the rotating motor 7 drives the motor roller 10 to rotate. When the bobbin 20 moves to a suitable position, the motor roller 10 drives the bobbin roller 6 to rotate through the friction force, and the bobbin roller 6 drives the bobbin 20 to rotate through the bobbin shaft 5. The motor roller 10 achieves an interference fit with the bobbin roller 6 through the adjustment part, which is used to ensure that the motor roller 10 is in close contact with the bobbin roller 6, thereby generating sufficient friction force to ensure that the motor roller 10 can drive the bobbin roller 6 to rotate smoothly. The staff adjusts the elastic force of the spring by increasing or decreasing the number of gaskets between the spring bracket 9 and the spring, thereby adjusting the contact distance between the motor roller 10 and the bobbin roller 6.

[0030] After the bobbin 20 moves to a suitable position, the second cylinder 14 drives the positioning plate 15 to extend toward the bobbin 20, and at the same time, the first cylinder 12 drives the slider 19 and the cylinder bracket 13 to move toward the bobbin 20, so that the yarn suction head 16 is close to the bobbin 20. After the controller detects that the bobbin 20 is in contact with the pressure sensor located on the positioning plate 15, it controls the first cylinder 12 to stop moving, and controls the second cylinder 14 to drive the positioning plate 15 to retract a suitable distance, so that there is a distance of 2 mm between the outer end of the positioning plate 15 and the yarn suction port 21 of the yarn suction head 16, so as to avoid contact between the yarn suction head 16 and the bobbin 20. When the bobbin 20 moves to a suitable position, the motor roller 10 on the rotating motor 7 is in close contact with the bobbin roller 6.

[0031] After the fan starts working, negative pressure is generated inside the yarn suction nozzle 16. The side walls on both sides of the positioning plate 15 are used to concentrate the airflow, so that there is a certain airflow pressure around the yarn suction nozzle 16. The yarn suction nozzle 16 finds the yarn head during the rotation of the yarn cone 20. When the yarn suction nozzle 16 finds the yarn head and sucks it into the connecting tube 17, the controller detects the yarn head through the photoelectric sensor, controls the fan to stop rotating, and controls the first cylinder 12 to reset. Then the motor drives the next yarn cone 20 to move to a suitable position through the chain 2.

[0032] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
