DETAILED DESCRIPTION

[0017] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0018] refer to Figure 1-8 As shown, the present invention discloses an inner tube tire installation device, comprising a tire conveying mechanism 1, a tire removing mechanism 2, an inner tube container 3, a first mechanical arm 4 and a second mechanical arm 5; The input end and the output end of the tire conveying mechanism 1 are used to input the outer tire a and output the assembled tire respectively; The tire removing mechanism 2 is arranged between the two ends of the tire conveying mechanism 1, and is provided with a movable claw device 21 for opening the outer tire a along the radial direction of the outer tire a, and a horizontally movable pusher 22 for pushing the two ends of the inner tire b into the grooves of the outer tire a; The inner tube container 3 is placed on the side of the tire conveying mechanism 1 and is used to provide the inner tube b to be assembled; The output end of the first mechanical arm 4 is provided with a fixed gripper 41 and a movable gripper 42 which can move towards each other to realize opening and closing, and are used to grab the inner tube b and place it into the outer tube a which is stretched in the tire changing mechanism 2; The output end of the second robot arm 5 is provided with an axial bracket 51 and a plurality of push plates 52 which are arranged in the axial bracket 51 and can move radially. The push plates 52 are synchronously expanded along the radial direction of the axial bracket 51 to expand the various parts of the inner tube b into a circle and push them into the groove of the outer tube a.

[0019] Through the above scheme, the present invention inputs the outer tire a by the tire conveying mechanism 1, and cooperates with the inner tire b in the inner tube container 3, and the tire removing mechanism 2, the first robot arm 4 and the second robot arm 5 perform the processes of fixing and opening the outer tire a, inserting the inner tube b and assembling the inner and outer tires. The whole process is automatically realized by machinery, and a high degree of automation is achieved, thereby greatly improving the production efficiency and yield rate; wherein, the claw device 21 and the push-out member 22 of the tire removing mechanism 2 can respectively fix the outer tire a and realize the pre-fixation of the inner tube b in the outer tire a, providing a good foundation for the subsequent inner and outer tire assembly process, thereby ensuring the completion rate of the assembly and avoiding the problem of the inner tube b not being assembled in place.

[0020] Specific embodiments of the present invention are shown below.

[0021] The tire conveying mechanism 1 comprises two roller conveyors, which are respectively arranged at the input end and the output end of the tire removing mechanism 2 .

[0022] See also Figure 5 The tire removing mechanism 2 includes two belt conveyors 23 connected with the tire conveying mechanism 1, and the ejector 22 is movably matched between the two belt conveyors 23; the claw device 21 includes a pair of upper claws 211 and a pair of lower claws 212 symmetrically arranged on both sides of the ejector 22, and the upper claws 211 and the lower claws 212 are respectively hooked on the edge positions of the inner wall groove of the outer tire a, so that a space can be left between the two for the inner tire b to enter the groove.

[0023] In some embodiments of the tire removing mechanism 2, the tire removing mechanism 2 further comprises a lifting bracket 24 for mounting the ejector 22, and the ejector 22 slides horizontally on the lifting bracket 24. Thus, the ejector 22 also has the function of lifting and moving, and can avoid the movement of the tire to avoid interference.

[0024] In some embodiments of the tire removing mechanism 2, the tire removing mechanism 2 further includes a machine platform 25, and two sliding brackets 26 that slide and fit on the machine platform 25 in a horizontal direction and are symmetrically arranged; the lower clamping claw 212 is fixed on the horizontal plane of the sliding bracket 26; the sliding bracket 26 is provided with a column 261, and the upper clamping claw 211 is lifted and fitted on the column 261. In this way, the synchronous horizontal movement of the upper clamping claw 211 and the lower clamping claw 212 on the same side can be achieved, and the height difference between the upper clamping claw 211 and the lower clamping claw 212 can be adjusted according to the actual tire size, and the upper clamping claw 211 can also avoid the movement of the tire when it is raised to avoid interference.

[0025] In some embodiments of the tire removing mechanism 2, a horizontally movable roller 27 is further provided on the outer side of the belt conveyor 23, and the horizontal moving direction of the roller 27 is perpendicular to the conveying direction of the belt conveyor 23 to enter or exit the upper surface of the belt conveyor 23, and the axis of the roller 27 is perpendicular to the upper surface of the belt conveyor 23. When the roller 27 enters the upper surface of the belt conveyor 23, the circumference of the outer tire a can be supported to prevent the outer tire a from shaking during tire installation. In this embodiment, there are four rollers 27, which are respectively located on both sides of the two sliding brackets 26.

[0026] The present invention further comprises a slide 6 for carrying the inner tube container 3, and the inner tube container 3 is slidably fitted on the upper surface of the slide 6. Thus, the two ends of the slide 6 can be respectively set as the loading position and the feeding position of the inner tube container 3, so as to avoid manual or other mechanical devices from being within the activity range of the first mechanical arm 4 when filling the inner tube container 3 with the inner tube b, thereby improving the production safety level.

[0027] The first robotic arm 4 and the second robotic arm 5 are both universal robotic arms, which can satisfy their output ends for conventional actions such as lifting, horizontal movement, and angular rotation.

[0028] See also Figure 6The output end of the first mechanical arm 4 is pivotally connected with a fixed bracket 43 and a movable bracket 44 that slides with the fixed bracket 43; the fixed gripper 41 and the movable gripper 42 are respectively mounted on the lower surface of the fixed bracket 43 and the movable bracket 44, and the opening and closing action of the fixed gripper 41 and the movable gripper 42 is realized through the relative movement of the two. When the fixed gripper 41 and the movable gripper 42 move away from each other, they can be tightly fitted on the inner side of the inner tube b and tighten the inner tube b into a shape similar to a runway. In the subsequent process, the two ends of the inner tube b can be firstly aligned with the grooves of the outer tube a so that the ejector 22 can firstly insert the two ends into the grooves.

[0029] See also Figure 7 and Figure 8 The output end of the second mechanical arm 5 is equipped with a connecting bracket 53, which is coaxially connected to the shaft bracket 51, and a screw motor 54 is arranged in the connecting bracket 53; the output end of the screw motor 54 is connected to a screw 55 that penetrates the shaft bracket 51; a movable block 56 is threadedly connected to the screw 55; two movable connecting members 57 are arranged between the movable block 56 and each push plate 52; the opposite ends of the two movable connecting members 57 are respectively pivotally matched to the movable block 56 and the bottom wall of the shaft bracket 51, and the opposite ends of the two movable connecting members 57 are pivotally matched to the inner wall of the push plate 52, and the adjacent parts of the two are provided with convex teeth 571 to achieve meshing. Therefore, by driving the movable block 56 by the screw motor 54, each push plate 52 can be synchronously extended and retracted on the circumference of the shaft bracket 51.

[0030] As mentioned above, each movable part in the equipment may be driven by a motor, a cylinder or a hydraulic cylinder or other machine capable of outputting linear reciprocating motion, and assisted by a guide rail or similar guide member that meets the travel requirements.

[0031] In addition, a protective fence can be added to the surrounding surface of the equipment of the present invention to prevent irrelevant personnel from entering and exiting the working area of ​​the robotic arm, thereby ensuring production safety.

[0032] The workflow of the present invention is as follows: (1) The tire conveying mechanism 1 delivers the outer tire a to the belt conveyor 23 of the tire removing mechanism 2, and the roller 27 on the side of the belt conveyor 23 moves horizontally and abuts against the circumferential surface of the outer tire a; (2) The first robot arm 4 grabs the inner tube b in the inner tube container 3, and the fixed gripper 41 and the movable gripper 42 move away from each other to support the inner tube b into a runway shape; (3) The first robot arm 4 places the inner tube b vertically into the outer tube a, and turns the inner tube b 90° so that it is in the same plane as the outer tube a; (4) The push piece 22 rises to enter the inner tube b, and then moves horizontally to push the "two ends of the track" of the inner tube b into the groove of the outer tube a. Then, the fixed gripper 41 and the movable gripper 42 move toward each other, and the output end of the first robot arm 4 exits the inner tube b. (5) The output end of the second mechanical arm 5 enters the inner tube b, and the screw motor 54 starts working. Through the linkage of the screw 55, the movable block 56 and the movable connecting member 57, the push plate 52 is pushed out of the shaft-shaped bracket 51, and each position of the inner tube b is pushed into the groove of the outer tube a; then, the push plate 52 is retracted into the shaft-shaped bracket 51, and the output end of the second mechanical arm 5 exits the inner tube b; (6) The roller 27 is reset, and the belt conveyor 23 starts to work, sending the assembled tire out of the tire removing mechanism 2.

[0033] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
