[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] like Figures 1 to 6 As shown, the present invention provides an embodiment of a giant engineering tire tread automatic picking device, 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, and 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 material receiving grid plate 7, and the material 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 material 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 transport grid plate 9, and the material transport grid plate 9 is installed on the first lifting slide 8 and can move up and down with the first lifting slide 8.

[0018] The transfer mechanism 4 also includes a loading grid 12, a grid shaft seat 13, a loading motor 14 and a first worm gear mechanism 15. One side of the loading grid 12 is fixed on the first lifting slide 8 and is located below the material transport grid 9. A rotating shaft 16 is fixed on one side of the material transport grid 9. The rotating shaft 16 is rotatably mounted on the grid shaft seat 13. The grid shaft seat 13 is fixed on the first lifting slide 8. The worm wheel of the first worm gear mechanism 15 is coaxially fixedly connected with the rotating shaft 16. The output shaft of the loading motor 14 is coaxially fixedly connected with the worm of the first worm gear mechanism 15. The loading motor 14 is used to drive the material transport grid 9 to rotate toward the loading grid 12.

[0019] The material transport grid 9 can pass through the gap of the material receiving grid 7. The end edges of the material receiving grid 7 and the loading grid 12 are fixed with anti-drop protrusions. After the heavier tread 3 slides onto the material receiving grid 7 and the loading grid 12, it will continue to slide forward and then be blocked by the anti-drop protrusions. The anti-drop protrusions can prevent the tread 3 from falling on the one hand, and on the other hand, can also enable the tread 3 to slide to a fixed position each time.

[0020] The working principle of the transfer mechanism 4 is: the material transport grid 9 is initially located below the material receiving grid 7. When the tread 3 on the material receiving grid 7 is moved, the material transport grid 9 and the loading grid 12 are first driven upward at the same time by the first lifting slide 8, and the material transport grid 9 passes through the material receiving grid 7 and moves to the top of the material receiving grid 7.

[0021] When the material transport grid 9 passes through the material receiving grid 7 from bottom to top, the tread 3 on the material receiving grid 7 can be lifted and separated from the material receiving grid 7. Then, the feeding motor 14 drives the material transport grid 9 to rotate a certain angle toward the upper material grid 12 through the first worm gear mechanism 15, so that the material transport grid 9 is in an inclined state. At this time, the tread 3 on the material transport grid 9 can slide down to the upper material grid 12, and then the feeding motor 14 drives the material transport grid 9 to flatten and reset. Then, the first lifting slide 8 drives the material transport grid 9 and the upper material grid 12 to move downward. At this time, the next tread 3 has not reached the material receiving grid 7. Therefore, the material transport grid 9 can pass through the material receiving grid 7 from top to bottom, and then the upper material grid 12 continues to move downward to the feeding mechanism 5, and the lifted tread 3 can be moved to the feeding mechanism 5.

[0022] The feeding mechanism 5 includes a pushing plate 10 and a pushing platform 11 . The pushing plate 10 is tilted and slidably mounted on the pushing platform 11 . One side of the pushing platform 11 is connected to the shutter vehicle 2 .

[0023] The feeding mechanism 5 also 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 of different heights of the louver vehicle 2, the second lifting slide 17 can drive the pushing platform 11 to move up and down to align with the blades of different heights of the louver vehicle 2. A slide groove 21 that passes through the pushing platform 11 is opened on the pushing platform 11. The push rod 18 is arranged at the bottom of the pushing platform 11 and is slidably installed in the slide groove 21. The lower end of the pushing plate 10 passes through the slide groove 21 and is fixedly connected with the push rod 18. The feeding screw 20 passes through the push rod 18 and is threadedly connected with 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 fixedly connected with the feeding screw 20 through a coupling, and the end of the feeding screw 20 is rotatably installed on the pushing platform 11.

[0024] The working principle of the feeding mechanism 5 is as follows: the upper end of the pushing plate 10 is a grid structure. After the loading grid 12 moves down to the pushing plate 10, the loading grid 12 can pass through the pushing plate 10 from the top to the bottom from the grid structure at the upper end of the pushing plate 10, and the tread 3 on the loading grid 12 is blocked by the grid structure of the pushing plate 10 and stays on the pushing plate 10, and then the tread 3 slides downward along the inclined surface of the pushing plate 10 to the pushing platform 11, and the feeding motor 19 drives the push rod 18 and the pushing plate 10 to move toward the shutter car 2 through the feeding screw 20, and pushes the tread 3 on the pushing platform 11 to the blades of the shutter car 2, completing the picking and conveying operation of the tread 3.

[0025] The page changing mechanism 6 is used to flip the blades of the venetian blind 2. The page changing mechanism 6 includes a second worm gear mechanism 22, a rotating arm 23, a telescopic arm 24, a clamping spring 25 and a push plate head 26. The second worm gear mechanism 22 is fixed on the second lifting slide 17. A page changing motor 27 is fixed to the bottom of the second lifting slide 17. The output shaft of the page changing motor 27 is coaxially fixedly connected to the worm of the second worm gear mechanism 22 through a coupling. One end of the rotating arm 23 is fixedly connected to the worm of the second worm gear mechanism 22 through a center axis. The telescopic arm 24 is slidably installed on the other end of the rotating arm 23. The clamping spring 25 abuts 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 venetian blind 2.

[0026] The page-changing mechanism 6 also includes a positioning seat 28, a limit plate 29, a slide rail 30 and a positioning cylinder 31. The positioning seat 28 is arranged on the side of 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, and the piston rod of the positioning cylinder 31 passes through the positioning seat 28 and is fixedly connected with the limit plate 29. The positioning cylinder 31 is used to push the shutter car 2 to abut against the push plate head 26.

[0027] The working principle of the page-changing mechanism 6 is: first, push the empty venetian blind trolley 2 between the page-changing mechanism 6 and the feeding mechanism 5, and align the blade gap at the bottom of the venetian blind trolley 2 with the push plate head 26, then the piston rod of the positioning cylinder 31 extends to make the limit plate 29 abut against the back of the venetian blind trolley 2, and then the positioning cylinder 31 continues to move to push the venetian blind trolley 2 to move toward the push plate head 26. During the movement of the venetian blind trolley 2, the push plate head 26 gradually inserts into the blade gap and can flip the empty blades upward to a tilted state.

[0028] After the blades of the current shutter vehicle 2 are placed on the tread 3, the page-changing motor 27 drives the rotating arm 23 to lift up through the second worm gear mechanism 22. When the rotating arm 23 is lifted up, it drives the telescopic arm 24 and the push plate head 26 to move up. At this time, the thrust provided by the pressing spring 25 always presses the push plate head 26 against the bottom of the blade of the shutter vehicle 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 with each other, the push plate Under the thrust of the abutment spring, the 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. Finally, the page-changing motor 27 rotates in the opposite 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 a horizontal state, so that the subsequent tread 3 can be smoothly placed on the blades of the shutter car 2.
