Description

Technical Field

[0001] The present invention relates to the technical field of tire transportation, and particularly to an automatic picking device for the tread of giant engineering tires. Background Art

[0002] During the tire production process, an automatic picking system is used to pick up, transport, and mechanically flip the tire treads, and finally stack multiple treads on a louver car for storage and transportation. Most of the existing automatic tire tread picking systems are for picking up semi-steel tire treads and lighter tire treads, with simple structures and single functions. When picking up and flipping heavier tire treads, the clamped parts of the tire treads are prone to stretching and distortion, affecting the uniformity index of the tire treads.

[0003] The patent with the authorization announcement number CN206735339U discloses an automatic picking system for tire tread rubber, including a material receiving device, a material pushing device, a material clamping device, a six-axis robot, and a louver car conveying device. The material receiving device includes a material receiving power roller group. The material pushing device is arranged below the material receiving power roller group, including a liftable bracket and a pallet group arranged on the bracket through a support rod group. The six-axis robot is arranged at the rear end of the material receiving power roller group. The material clamping device is arranged on the robotic arm of the six-axis robot and includes upper and lower claw groups that open and close. Each claw group includes a material clamping transmission belt group. The louver car conveying device includes a longitudinal walking channel arranged beside the material receiving power roller group and composed of two rows of roller groups. The loading station of the louver car in the longitudinal walking channel corresponds to the rear part of the material receiving power roller group. A flap manipulator for turning the flaps of each louver on the louver car is arranged at the loading station of the louver car. However, this patent still has some deficiencies: 1. The material clamping transmission belt group only pulls the heavier tire treads through friction, easily causing multiple positions of the tire treads to be tightened and distorted and prone to slipping. 2. The six-axis robot is difficult to maintain. Summary of the Invention

Detailed implementation manners

[0021] Next, the technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

[0022] As Figures 1 to 6 shown, the present invention provides an embodiment of an automatic picking device for the tread of giant engineering tires, including a conveyor belt 1 and a shutter car 2. The shutter car 2 is used to store the tread 3 conveyed by the conveyor belt 1. It also includes a temporary storage mechanism, a transfer mechanism 4, a feeding mechanism 5 and a page-changing mechanism 6. The temporary storage mechanism includes a receiving grid plate 7. The receiving grid plate 7 is connected to the discharge end of the conveyor belt 1. After the tread 3 moves along the conveyor belt 1 to the discharge end of the conveyor belt 1, the tread 3 can automatically slide down onto the receiving grid plate 7 so that the transfer mechanism 4 can pick up the heavier tread 3 and move it to the feeding mechanism 5. The transfer mechanism 4 includes a first lifting slide 8 and a material-carrying grid plate 9. The material-carrying grid plate 9 is installed on the first lifting slide 8 and can move up and down with the first lifting slide 8.

[0023] The transfer mechanism 4 further includes a loading grid plate 12, a grid plate shaft seat 13, a loading motor 14 and a first worm and worm gear mechanism 15. One side of the loading grid plate 12 is fixed on the first lifting slide 8 and is located below the material-carrying grid plate 9. A rotating shaft 16 is fixed on one side of the material-carrying grid plate 9. The rotating shaft 16 is rotatably installed on the grid plate shaft seat 13. The grid plate shaft seat 13 is fixed on the first lifting slide 8. The worm wheel of the first worm and worm gear mechanism 15 is coaxially and fixedly connected to the rotating shaft 16. The output shaft of the loading motor 14 is coaxially and fixedly connected to the worm of the first worm and worm gear mechanism 15. The loading motor 14 is used to drive the material-carrying grid plate 9 to rotate towards the loading grid plate 12.

[0024] The material transporting grating plate 9 can pass through the gap of the material receiving grating plate 7. Anti-falling protrusions are fixed at the end edges of the material receiving grating plate 7 and the material loading grating plate 12. After the relatively heavy tread 3 slides onto the material receiving grating plate 7 and the material loading grating plate 12, it will continue to slide forward and then be blocked by the anti-falling protrusions. On the one hand, the anti-falling protrusions can prevent the tread 3 from falling, and on the other hand, they can also make the tread 3 slide to a fixed position each time.

[0025] The working principle of the transfer mechanism 4 is as follows: In the initial state, the material transporting grating plate 9 is located below the material receiving grating plate 7. When moving the tread 3 on the material receiving grating plate 7, first, the first lifting slide 8 drives the material transporting grating plate 9 and the material loading grating plate 12 to rise simultaneously. The material transporting grating plate 9 passes through the material receiving grating plate 7 and moves above the material receiving grating plate 7.

[0026] During the process of the material transporting grating plate 9 passing through the material receiving grating plate 7 from bottom to top, it can lift the tread 3 on the material receiving grating plate 7 and separate it from the material receiving grating plate 7. Then, the material loading motor 14 drives the material transporting grating plate 9 to rotate a certain angle towards the material loading grating plate 12 through the first worm and worm gear mechanism 15, making the material transporting grating plate 9 in an inclined state. At this time, the tread 3 located on the material transporting grating plate 9 can slide down onto the material loading grating plate 12. Then, the material loading motor 14 drives the material transporting grating plate 9 to return to the flat state. After that, the first lifting slide 8 drives the material transporting grating plate 9 and the material loading grating plate 12 to move down. At this time, the next tread 3 has not reached the material receiving grating plate 7, so the material transporting grating plate 9 can pass through the material receiving grating plate 7 from top to bottom. Then, the material loading grating plate 12 continues to move down to the feeding mechanism 5, and it can move the tread 3 it holds to the feeding mechanism 5.

[0027] The feeding mechanism 5 includes a pushing plate 10 and a pushing platform 11. The pushing plate 10 is inclined. The pushing plate 10 is slidably installed on the pushing platform 11. One side of the pushing platform 11 is connected to the shutter car 2.

[0028] The feeding mechanism 5 further includes a second lifting slide 17, a push rod 18, a feeding motor 19, and a feeding screw 20. The pushing platform 11 is fixed on the second lifting slide 17. The second lifting slide 17 can drive the pushing platform 11 to move up and down. When it is necessary to move the tread 3 to the blades at different heights of the shutter car 2, the second lifting slide 17 drives the pushing platform 11 to move up and down to align with the blades at different height positions of the shutter car 2. A through groove 21 is formed in the pushing platform 11. The push rod 18 is arranged at the bottom of the pushing platform 11 and is slidably installed in the through groove 21. The lower end of the pushing plate 10 passes through the through groove 21 and is fixedly connected to the push rod 18. The feeding screw 20 passes through the push rod 18 and is threadedly connected to the push rod 18. The feeding motor 19 is fixed at the bottom of the pushing platform 11. The output shaft of the feeding motor 19 is coaxially and fixedly connected to the feeding screw 20 through a coupling. The end of the feeding screw 20 is rotatably installed on the pushing platform 11.

[0029] The working principle of the feeding mechanism 5 is as follows: The upper end of the pusher plate 10 is a grid structure. After the feeding grid plate 12 moves down to the pusher plate 10, the feeding grid plate 12 can pass through the pusher plate 10 from top to bottom through the grid structure at the upper end of the pusher plate 10. The tread 3 on the feeding grid plate 12 is blocked by the grid structure of the pusher plate 10 and stays on the pusher plate 10. Then, the tread 3 slides down along the inclined surface of the pusher plate 10 to the pushing platform 11. The feeding motor 19 drives the push rod 18 and the pusher plate 10 to move towards the shutter cart 2 through the feeding screw rod 20, and pushes the tread 3 on the pushing platform 11 onto the blades of the shutter cart 2, completing the picking and conveying operation of the tread 3.

[0030] The page-changing mechanism 6 is used to flip the blades of the shutter cart 2. The page-changing mechanism 6 includes a second worm and worm gear mechanism 22, a rotating arm 23, a telescopic arm 24, a pressing spring 25, and a push plate head 26. The second worm and worm gear mechanism 22 is fixed on the second lifting slide 17. The bottom of the second lifting slide 17 is fixed with a page-changing motor 27. The output shaft of the page-changing motor 27 is coaxially and fixedly connected to the worm of the second worm and worm gear mechanism 22 through a coupling. One end of the rotating arm 23 is fixedly connected to the worm gear of the second worm and worm gear mechanism 22 through a central shaft. The telescopic arm 24 is slidably installed at the other end of the rotating arm 23. The pressing spring 25 is abutted between the rotating arm 23 and the telescopic arm 24. One end of the push plate head 26 is fixedly connected to the telescopic arm 24, and the other end of the push plate head 26 can abut against the blades of the shutter cart 2.

[0031] The page-changing mechanism 6 further includes a positioning seat 28, a limiting plate 29, a slide rail 30, and a positioning cylinder 31. The positioning seat 28 is arranged beside the push plate head 26. The slide rail 30 is slidably installed on the positioning seat 28. The positioning cylinder 31 is fixed on the positioning seat 28. The piston rod of the positioning cylinder 31 passes through the positioning seat 28 and is fixedly connected to the limiting plate 29. The positioning cylinder 31 is used to push the shutter cart 2 to abut against the push plate head 26.

[0032] The working principle of the page-changing mechanism 6 is as follows: First, the empty shutter cart 2 is pushed between the page-changing mechanism 6 and the feeding mechanism 5, and the blade gap at the bottom of the shutter cart 2 is aligned with the push plate head 26. Then, the piston rod of the positioning cylinder 31 extends to make the limiting plate 29 abut against the back of the shutter cart 2. Then, the positioning cylinder 31 continues to act to push the shutter cart 2 towards the push plate head 26. During the movement of the shutter cart 2, the push plate head 26 gradually inserts into the blade gap and can turn the empty blade upwards to an inclined state.

[0033] After the tread 3 is placed on the blades of the current shutter cart 2, the page-changing motor 27 drives the rotating arm 23 to lift upward through the second worm and worm gear mechanism 22. When the rotating arm 23 lifts upward, it drives the telescopic arm 24 and the push plate head 26 to move upward. At this time, the thrust provided by the abutting spring 25 always presses the push plate head 26 against the lower part of the blade of the shutter cart 2, so that the push plate head 26 can slide upward along the surface of the blade. When the push plate head 26 slides upward to the top of the inclined blade, since the tops of multiple inclined blades are staggered from each other, the push plate head 26 will slide out of the upper end of the previous inclined blade and directly abut against the upper end of the next inclined blade under the thrust of the abutting spring. Finally, the page-changing motor 27 rotates in the reverse direction to drive the rotating arm 23 to move downward, and the rotating arm 23 drives the telescopic arm 24 and the push plate head 26 to move downward. At this time, the previous inclined blade is located below the push plate head 26. Therefore, when the push plate head 26 moves downward, it will push the inclined blade to flip downward together until it flips to the horizontal state, so that the subsequent tread 3 can be smoothly placed on the blades of the shutter cart 2.
