DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-4As shown, it includes a gantry and a turning device, and also includes a conveyor belt 42. The conveyor belt 42 is located in the gantry. A fixed plate 40 is installed on the conveyor belt 42. At least three tire trays 41 are fixed on the fixed plate 40. A grabbing device and a transport device are installed on the gantry. The gantry is divided into a transport walking frame 11 and a grabbing walking frame 21. The transport device walks on the transport walking frame 11, and the grabbing device walks on the grabbing walking frame 21. A grabbing buckle 22 is provided on the grabbing device, and the tire is buckled and grabbed by the grabbing buckle 22. The transport device includes a transport frame 10 and the transport hanging shaft 12, wherein the flipping device is located between the grasping device and the transport device, and the grasping device, the transport device and the flipping device are all controlled by a travel switch to start, stop, and return, etc. The flipping device includes a flip main bracket 30, a placement table bracket 31, a motor bracket 33, a clamping assembly and an auxiliary limiting assembly, wherein the placement table bracket 31 is located above the flip main bracket 30, the motor bracket 33 is located on the side of the flip main bracket 30, the clamping assembly is located inside the flip main bracket 30, and the auxiliary limiting assembly is located on the placement table bracket 31;

[0025] A placing table 35 is fixed at the center of the placing table bracket 31, wherein an auxiliary plate 36 is fixed to the side of the placing table 35 close to the placing table rotating shaft 32, and a notch is opened in the placing table 35. A flip motor 34 is fixedly installed on the motor bracket 33, and the flip motor 34 is installed on the placing table rotating shaft 32 through a chain, wherein the placing table bracket 31 is fixed on the placing table rotating shaft 32, and the auxiliary plate 36 and the placing table 35 are installed perpendicular to each other. The auxiliary plate 36 is arranged in an arc shape, and the outer periphery of the tire can be supported by the auxiliary plate 36 to prevent the tire from slipping when the placing table 35 rotates. A notch is opened in the placing table 35, and the opening direction of the notch is away from the auxiliary plate 36. The placing table 35 is arranged as an inward concave disc.

[0026] The clamping assembly includes a clamping hydraulic cylinder 50, a clamping connecting rod 51 and a clamping block 54, wherein the clamping hydraulic cylinder 50 is rotatably connected to the flip main bracket 30, and two symmetrically arranged mounting blocks 53 are fixed on the flip main bracket 30. Two mutually meshing clamping blocks 54 are movably mounted on each mounting block 53, so that the four clamping blocks 54 can move inward at the same time to push the tire to the center, which is convenient for the subsequent grasping device to position and grasp. The tire can also be clamped by the clamping block 54 to prevent the tire from shaking. A clamping shaft 52 is fixed to the bottom of the clamping block 54, and the other end of the clamping shaft 52 is fixed to the clamping connecting rod 51. The center of the clamping connecting rod 51 is rotatably mounted on the flip main bracket 30. At the center, the hydraulic rod on the clamping hydraulic cylinder 50 is connected to the end face of one side of the clamping link 51 near its center. The clamping link 51 is symmetrically arranged in three sections and is hinged to each other. The outermost section of the clamping link 51 is fixed to the clamping shaft 52. The total length of the two clamping blocks 54 on each side is greater than the width of the flip main bracket 30. Each clamping block 54 is movably connected with a number of rollers, and the roller material is rubber to avoid damage to the tire. Through the setting of the rollers, the rollers can rotate during the process of the clamping block 54 clamping the tire, which greatly reduces the friction between the clamping block 54 and the tire during the clamping process and avoids damage to the surface of the tire embryo.

[0027] The auxiliary limiting assembly includes an auxiliary limiting rod 60 installed at the notch of the placement table 35, and an auxiliary connecting block 63 is fixed to the end face of one side of the bottom of the placement table bracket 31. The auxiliary limiting rod 60 is rotatably connected to the auxiliary connecting block 63 through an auxiliary rotating shaft 62. Two symmetrically arranged abutment plates 61 are also welded on the flip main bracket 30. A torsion spring is installed at the rotation of the auxiliary limiting rod 60, and the torsion spring is installed on the auxiliary rotating shaft 62. A groove is provided on the bottom cross bar of the placement table bracket 31. The auxiliary limiting rod 60 is L-shaped, and its long section is at the placement table 35. In the notch, its short section is in the groove, and there is a certain friction between the short section and the inner wall of the groove, so that when the auxiliary limiting rod 60 is not restricted by the abutment plate 61, it can maintain its original state for a period of time. When the auxiliary limiting rod 60 enters the interior of the tire, the elastic force of the torsion spring can overcome the friction between the auxiliary limiting rod 60 and the groove, so that the long section is stuck in the tire, thereby limiting the tire from falling off, effectively preventing the tire from falling off due to the vibration generated by the motor operation during the rotation of the placement table bracket 31, and further increasing the stability of the tire during flipping.

[0028] Working principle: At the beginning of operation, the transport hanging shaft 12 on the transport frame 10 removes the tire from the previous device, and then the motor is used to move the transport device horizontally with the tire. When the transport frame 10 moves to the top of the flip device of the placement table 35, the transport frame 10 can touch the limit switch, and the transport frame 10 can return. At the same time, the flip motor 34 is started to make the placement table shaft 32 drive the placement table bracket 31 to rotate upward, so that the placement table 35 abuts against the tire and pushes the tire. Under the movement of the return of the transport frame 10 and the limit of the placement table 35, the tire is pushed upward. Under the braking force, the tire will be removed from the transport hanging shaft 12 and fall onto the placement table 35. The auxiliary plate 36 will support the tire to prevent it from falling. At this time, the auxiliary limiting rod 60 will enter the inside of the tire. When the placement table bracket 31 rotates to the maximum angle of 85°, the tire is completely on the placement table 35. At this time, the torsion spring force can overcome the friction between the auxiliary limiting rod 60 and the groove and rotate it completely, so that the long section is stuck inside the tire. Then the flip motor 34 can start to rotate in the opposite direction by itself, so that the placement table bracket 31 is gradually flattened, completing the removal and flipping of the tire.

[0029] When the placement table bracket 31 is lowered, the short section of the auxiliary limiting rod 60 will abut against the abutment plate 61, thereby overcoming the elastic force of the torsion spring and being squeezed into the groove of the placement table bracket 31. At this time, the long section of the auxiliary limiting rod 60 can be in a vertical position with the tire, so that the tire is no longer affected by the auxiliary limiting rod 60.

[0030] When the placement table bracket 31 is completely flat, the grabbing device can be started, driving the grabbing buckle 22 to move above the placement table 35, and then the grabbing buckle 22 will move into the tire and buckle the tire from the inside to avoid clamping the tire from the outside and causing damage to the tire. Then the grabbing device can return to the original route and place the tire on the tire tray 41, and convey it to the next device through the conveyor belt 42. At this time, the entire process of transporting, picking up, flipping, grabbing, and conveying the tire can be completed. When the next tire needs to be flipped, the above process can be repeated.

[0031] In summary, the inward-locking tire blank flipping part, through the setting of the auxiliary limiting rod 60, allows its long section to be stuck inside the tire during the rotation of the placement table 35, thereby limiting the tire and preventing it from falling, effectively preventing the tire from falling due to the vibration generated by the motor operation during the rotation of the placement table bracket 31, and further increasing the stability of the tire during flipping; through the setting of the clamping assembly, the four clamping blocks 54 can move inward at the same time, pushing the tire to the center, facilitating the subsequent positioning and grasping of the grasping device, and can also clamp the tire through the clamping block 54, effectively preventing the tire from shaking; through the rubber roller clamping, the tire is effectively avoided from being damaged, and the roller can rotate during the process of the clamping block 54 clamping the tire, greatly reducing the friction between the clamping block 54 and the tire during the clamping process, further avoiding damage to the surface of the tire blank.
