Description

Technical Field

[0001] The invention relates to the technical field of tire conveying, and in particular to a tire conveying device. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. They are usually installed on metal wheels, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. After the tires are produced, they need to be transported to the designated location by conveyors for further processing. In order to achieve rapid transportation of tires, the tires are generally piled up on the conveyor, and pallets are manually placed at the bottom of the piled tires to disperse the pressure of the tires and reduce the friction between the tires and the conveyor.

[0003] The Chinese patent document with the authorization announcement number CN207192321U discloses an automatic tire stacker, which stacks tires through cylinders and motors, thereby ensuring the concentricity of the stacked tires and being adaptable to the use requirements of different tires.

[0004] However, the structural design of the above-mentioned related technology: although the tires can be stacked up automatically, a pallet still needs to be placed manually on the bottom of the stacked tires. If the length of the pallet is too long, although the tires can be completely placed on the pallet, a large space will be left between the two pallets. When the two pallets collide during transportation, there will be space for the tires on the pallets to fall over, thereby affecting the stability of tire transportation. If the width and length of the pallet match the diameter of the tire, errors are likely to occur when the pallet is placed manually, causing the tire to protrude from the pallet, causing the tire to contact the conveying rollers on the conveyor, which can easily cause the tire and the pallet to rotate on the conveyor.

[0005] Therefore, a tire conveying device is proposed to solve the above problems. Summary of the invention

[0006] The present invention provides a tire conveying device, aiming to solve the problem in the related art that when a pallet is placed on the bottom of the tire, the tire is easy to protrude from the pallet and thus comes into contact with a conveying roller.

[0007] The tire conveying device of the present invention comprises a conveyor and a clamping mechanism, wherein the clamping mechanism is located above the conveyor to stack tires, and is characterized in that the conveyor is used to convey tires, a feeding mechanism is provided on one side of the conveyor, and a stacking mechanism is connected to the clamping mechanism to drive the clamping mechanism to move upward;

[0008] The feeding mechanism includes a material storage assembly for storing the tray, a transmission assembly is installed on the material storage assembly, a material pushing assembly is provided on the transmission assembly, the transmission assembly includes a mounting frame installed on the material storage assembly and a reciprocating screw 1 rotatably connected to the mounting frame, the reciprocating screw 1 is used to drive the material pushing assembly to move back and forth, a bevel gear 1 is installed on the reciprocating screw 1, a bevel gear 2 is meshed on the bevel gear 1, and a rotating shaft capable of driving the bevel gear 2 to rotate is provided on the bevel gear 2;

[0009] The stacking mechanism includes a driving assembly, which can move up and down along the length direction of the clamping mechanism. The clamping mechanism is installed on the driving assembly. The driving assembly includes a connecting plate, a reciprocating screw 2, a lifting plate and a limit shaft. The reciprocating screw 2 is rotatably connected to the bottom of the connecting plate, the lifting plate is threadedly connected to the reciprocating screw 2, the limit shaft is installed on the reciprocating screw 2, and the limit shaft can be inserted into the rotating shaft. After the clamping mechanism stacks the tires, the reciprocating screw 1 drives the pushing assembly to move through the rotation of the rotating shaft to move the pallet to the bottom of the tire, and then the clamping mechanism allows the tire to fall onto the pallet and the tire is coaxially arranged with the pallet.

[0010] Beneficial effect: The stacking mechanism drives the clamping mechanism to stack the tires. When the tires are stacked, the rotating shaft drives the pushing assembly on the reciprocating screw 1 to move through the bevel gear 1 on the bevel gear 2. When the pushing assembly moves, it pushes the pallet in the storage assembly to move onto the conveyor and is placed at the bottom of the stacked tires. Then the stacking mechanism uses the clamping mechanism to make the stacked tires fall onto the pallet, and the clamping mechanism makes the tires and the pallet coaxially arranged to avoid the tires protruding out of the pallet, thereby preventing the tires from directly contacting the conveyor and causing the pallet and tires to rotate, thereby improving the stability of the tire transportation process.

[0011] Preferably, the material storage assembly includes a storage seat arranged on one side of the conveyor and a limiting rod installed on the inner bottom wall of the storage seat, and the limiting rod is elastically slidably connected to a supporting plate in the vertical direction for placing a pallet, and the pallet is provided with a hole adapted to the limiting rod.

[0012] The effect is that the support plate can automatically drive the next pallet to move up after pushing one pallet away, so that the pallet can be automatically loaded without manual placement, making the placement of the pallet more convenient.

[0013] Preferably, the rotating shaft is rotatably connected to the mounting frame, a mainspring for driving the rotating shaft to rotate is arranged on the rotating shaft, an inner spline groove is provided on the top end of the rotating shaft, a lifting rod is elastically slidably connected to the inner spline groove of the rotating shaft along the vertical direction, a limit block capable of inserting bevel gear 2 is installed on the lifting rod, and a groove matching the limit block is provided on the bevel gear 2.

[0014] The effect is that when the lifting rod is squeezed, the lifting rod can drive the limit block to move out of the second bevel gear, so that the rotating shaft cannot drive the reciprocating screw first to rotate.

[0015] Preferably, the pusher assembly comprises a movable frame threadedly connected to a reciprocating screw and a pusher plate arranged on the movable frame, and a groove for accommodating a tray is formed at the bottom of the pusher plate.

[0016] Preferably, the stacking mechanism also includes a mounting plate, two winches and four guide rails, the four guide rails are respectively installed at the four corners of the bottom of the mounting plate, the two winches are installed on the mounting plate, a steel wire rope is wound on the winches, the connecting plate is arranged on the steel wire rope, and the connecting plate is slidably connected to the guide rails.

[0017] The effect is that the release of the wire rope by the winch can drive the driving assembly to move downward, thereby driving the clamping mechanism to move downward to a specified position to facilitate the stacking of tires. After the driving assembly drives the clamping mechanism to move downward, the limit shaft is inserted into the rotating shaft and squeezes the lifting rod to prevent the reciprocating screw one from rotating during the stacking of tires. The rotation of the reciprocating screw two can drive the clamping mechanism to move up and down, thereby continuously stacking and clamping the tires. When the stacking is completed, the driving assembly drives the clamping mechanism to move upward and disengage the limit shaft from the rotating shaft, so that the pushing assembly pushes the pallet to move.

[0018] Preferably, the clamping mechanism includes a mounting tube, a fixing part, a fixing plate and a clamping assembly, the fixing part is mounted on the top of the mounting tube, the fixing part is mounted on the lifting plate, the clamping assembly is arranged on the fixing plate, an extrusion block is arranged at the bottom of the clamping assembly, and a positioning assembly is arranged on the inner bottom wall of the mounting tube.

[0019] Preferably, the clamping assembly includes a lifting column, a hinge and a telescopic component, and the hinge includes four hinge seats, four hinge plates and four sliding rods. The four hinge seats are installed in a ring shape on the outside of the lifting column with the axis of the lifting column as the center, and the hinge seats and the sliding rods are hinged to the two ends of the hinge plates respectively. One end of the sliding rod passes through the mounting tube and extends to the outside of the mounting tube. A clamping plate is installed at one end of the sliding rod.

[0020] Preferably, the positioning assembly includes a turntable rotatably connected to the bottom wall of the mounting tube and three movable parts arranged on the turntable, the turntable is provided with three limiting grooves distributed in a circular array, and the movable parts are slidably arranged in the limiting grooves.

[0021] Preferably, the movable member comprises a movable rod slidably disposed in a limiting groove and a protrusion mounted on the top end of the movable rod, and a positioning member located at the bottom end of the mounting tube is mounted on the bottom end of the movable rod.

[0022] The effect is that when the pallet is placed at the bottom of the stacked tires, the telescopic member drives the lifting column to move downward, and the lifting column squeezes the protrusion through the squeezing block, so that the three positioning members move away from each other, and the positioning members are stretched in the holes of the pallet to position the pallet.

[0023] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: when the tires are stacked, the rotating shaft drives the pushing assembly to move through the matching arrangement of bevel gear 2, bevel gear 1 and reciprocating screw 1, and the pushing assembly drives the pallet to move onto the conveyor and is placed at the bottom of the stacked tires, and then the clamping mechanism makes the stacked tires fall onto the pallet, and the tires and the pallet are coaxially arranged through the clamping mechanism to avoid the tires protruding out of the pallet, thereby preventing the tires from directly contacting the conveyor and causing the pallet and the tires to rotate, thereby improving the stability of the tire transportation process.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 8 As shown, the tire conveying device of the present invention comprises a conveyor 10, a feeding mechanism 20, a stacking mechanism 30 and a clamping mechanism 40. The conveyor 10 is located below the clamping mechanism 40 and is used to convey tires. The feeding mechanism 20 is located on one side of the conveyor 10 and is used to place a pallet. The clamping mechanism 40 is arranged on the stacking mechanism 30 and is used to clamp the tire. The conveyor 10 conveys the tire to the bottom of the clamping mechanism 40. At this time, the stacking mechanism 30 drives the clamping mechanism 40 to stack the tires. After the tires are stacked, the feeding mechanism 20 automatically pushes the pallet to the bottom of the stacked tires to receive the stacked tires.

[0039] like Figure 1 and Figure 2As shown, the conveyor 10 includes a frame 11, a conveying roller 12 and two guide assemblies. There are multiple conveying rollers 12, and multiple conveying rollers 12 are arranged on the frame 11 at equal intervals along the length direction of the frame 11. The multiple conveying rollers 12 are transmission-connected, and one of the conveying rollers 12 is connected to an external drive to drive multiple conveying rollers 12 to rotate synchronously. The frame 11 is rotationally connected to the conveying rollers 12. The two guide assemblies are respectively installed on both sides of the top of the frame 11, and the guide assemblies include a fixed frame 13, a guide plate 14 and a plurality of rotating columns 15. The fixed frame 13 is installed on the top of the frame 11, and the guide plates 14 in the two guide assemblies are arranged in an eight-shaped shape. Multiple rotating columns 15 are arranged inside the guide plate 14 at equal intervals along the trajectory of the guide plate 14, and the rotating column 15 is rotationally connected to the guide plate 14.

[0040] The tire is moved by the rotation of the conveying roller 12 . When the tire moves between the two guide plates 14 , the tire can be centered by the limiting of the two guide plates 14 , which is convenient for subsequent stacking processing.

[0041] Continue to refer Figure 1 and Figure 2 As shown, the feeding mechanism 20 includes a material storage assembly 21, a transmission assembly 22 and a material pushing assembly 23. The material storage assembly 21 is arranged on one side of the frame 11, the transmission assembly 22 is installed on the top of the material storage assembly 21, and the material pushing assembly 23 is arranged on the transmission assembly 22.

[0042] like Figure 2 and Figure 3 As shown, the storage assembly 21 includes a storage seat 211, a limiting rod 212 and a supporting plate 214. The storage seat 211 has an opening on one side and the top close to the frame 11. The top of the storage seat 211 and the top of the conveying roller 12 are located in the same plane, and the limiting rod 212 is installed on the inner bottom wall of the storage seat 211. The supporting plate 214 is slidably connected to the outside of the limiting rod 212, and the outer wall of the supporting plate 214 is slidably connected to the inner wall of the storage seat 211. An elastic member 213 is installed between the inner bottom wall of the storage seat 211 and the supporting plate 214 to drive the supporting plate 214 to move upward. In this embodiment, the elastic member 213 is a spring. The tray is placed on the supporting plate 214, and a hole adapted to the limiting rod 212 is opened on the tray.

[0043] like Figures 2 to 4As shown, the transmission assembly 22 includes a mounting frame 221, a reciprocating screw 1 222, a bevel gear 1 223, a bevel gear 2 24, a rotating shaft 225 and a barrel 226. The mounting frame 221 has support frames on both sides, and the mounting frame 221 is mounted on the top of the storage seat 211 through the support frames. The shape of the mounting frame 221 is U-shaped. One end of the reciprocating screw 1 222 is rotatably connected to the inner wall of the mounting frame 221, and the other end of the reciprocating screw 1 222 passes through the mounting frame 221 and extends to the outside of the mounting frame 221. The pusher assembly 23 is threadedly connected to the reciprocating screw 1 222. The bevel gear 1 223 is mounted on the other end of the reciprocating screw 1 222, and the bevel gear 2 24 is meshed with the bevel gear 1 223.

[0044] The rotating shaft 225 is arranged at the top end of the bevel gear 224, and an inner spline groove is opened at the top end of the rotating shaft 225. The spring box 226 is arranged on the outside of the rotating shaft 225. A spring (not shown in the figure) is installed inside the spring box 226, and one end of the spring is installed on the rotating shaft 225. A support plate is installed on one side of the top of the mounting frame 221, and the spring box 226 is installed on the support plate of the mounting frame 221. The support plate of the mounting frame 221 is rotatably connected with the rotating shaft 225.

[0045] A lifting rod 227 is slidably connected in the inner spline groove of the rotating shaft 225. The bottom end of the lifting rod 227 passes through the rotating shaft 225 and extends to the outside of the rotating shaft 225. A limit block 228 is installed at the bottom end of the lifting rod 227. A groove matching the limit block 228 is opened on the bevel gear 224. A slider matching the inner spline groove is installed on the top of the lifting rod 227. An elastic member 229 is installed between the inner bottom wall of the inner spline groove and the slider on the lifting rod 227. The elastic member 229 is a spring.

[0046] When the rotating shaft 225 rotates, the rotating shaft 225 can drive the bevel gear 224 to rotate through the limit block 228 on the lifting rod 227. The bevel gear 224 can drive the pushing assembly 23 on the reciprocating screw 222 to move back and forth along the length direction of the reciprocating screw 222 through the bevel gear 1 223. When the pushing assembly 23 moves, it can push the pallet to the bottom of the tire.

[0047] like Figure 2 and Figure 3As shown, the pusher assembly 23 includes a movable frame 231, a connecting strip 232 and a pusher plate 233. The movable frame 231 is threadedly connected to the reciprocating screw 222, and the top of the movable frame 231 is slidably connected to the inner bottom wall of the mounting frame 221. The connecting strip 232 is installed on one side of the movable frame 231, and the pusher plate 233 is installed on one side of the connecting strip 232. The bottom of the pusher plate 233 contacts the top of the storage seat 211, and the pusher plate 233 is in a U-shape. A groove for accommodating a tray is provided at the bottom of the pusher plate 233. The tray can be limited by the groove on the pusher plate 233 to prevent the elastic member 213 from driving the tray on the supporting plate 214 to pass over the pusher plate 233.

[0048] The reciprocating screw 222 drives the push plate 233 to move toward the bottom of the tire through the connecting strip 232 on the movable frame 231. At the same time, the push plate 233 drives a pallet to move onto the conveying roller 12 and is placed at the bottom of the tire. When the pallet moves to the bottom of the tire, the reciprocating screw 222 drives the push plate 233 to move in the opposite direction. During the movement, the push plate 233 can squeeze the pallet in the storage seat 211 through the movable frame 231 and the connecting strip 232 to prevent the pallet from moving up, thereby ensuring the stability of the pallet when loading.

[0049] like Figure 1 and Figure 2 As shown, the stacking mechanism 30 includes a guide rail 31, a mounting plate 32, a hoist 33 and a drive assembly 35. There are four guide rails 31, which are respectively mounted at the four corners of the bottom of the mounting plate 32, and the four guide rails 31 are respectively located on both sides of the frame 11. There are two hoists 33, which are respectively mounted on both sides of the top of the mounting plate 32. A steel wire rope 34 is wound around the hoist 33, and the bottom end of the steel wire rope 34 is mounted on the drive assembly 35. The drive assembly 35 is slidably connected to the guide rail 31, and the clamping mechanism 40 is mounted on the drive assembly 35. The clamping mechanism 40 can be driven to move up and down by the drive assembly 35 to stack the tires.

[0050] like Figures 1 to 5 As shown, the driving assembly 35 includes a connecting plate 351, a motor 352, a reciprocating screw 2 353, a lifting plate 354 and a limiting shaft 355. The connecting plate 351 is located above the lifting plate 354, the motor 352 is installed on the top side of the connecting plate 351, the top end of the reciprocating screw 2 353 is rotatably connected to the bottom side of the connecting plate 351, and the top end of the reciprocating screw 2 353 is fixed to the output shaft of the motor 352. The lifting plate 354 is threadedly connected to the reciprocating screw 2 353, and the clamping mechanism 40 is installed at the bottom of the lifting plate 354. The limiting shaft 355 is installed at the bottom end of the reciprocating screw 2 353, and the limiting shaft 355 is an external spline shaft, and the limiting shaft 355 is adapted to the internal spline groove on the rotating shaft 225.

[0051] like Figure 2 and Figure 5 As shown, slide plates 357 are installed on both sides of the connecting plate 351, and the slide plates 357 are slidably connected to the two adjacent guide rails 31. The wire rope 34 on the winch 33 is connected to the top of the slide plate 357. A guide rod 356 is installed at the bottom of the connecting plate 351, and the lifting plate 354 is slidably connected to the outer side of the guide rod 356.

[0052] The winch 33 drives the connecting plate 351 on the slide plate 357 to move downward through the wire rope 34, thereby driving the lifting plate 354 and the clamping mechanism 40 to move downward. When the clamping mechanism 40 moves downward to the specified position, the limit shaft 355 is inserted into the inner spline groove of the rotating shaft 225. At this time, the limit shaft 355 squeezes the lifting rod 227 to make the limit block 228 extend out of the bevel gear 224, and then the motor 352 drives the reciprocating screw 2 353 to rotate. During the rotation of the reciprocating screw 2 353, the limit shaft 355 drives the rotating shaft 225 to rotate so that the spring in the spring box 226 accumulates force. At the same time, the lifting plate 354 drives the clamping mechanism 40 to move back and forth along the length direction of the reciprocating screw 2 353.

[0053] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the clamping mechanism 40 includes a mounting cylinder 41, a fixing member 42, a fixing plate 43 and a clamping assembly 44. The fixing member 42 is mounted on the top of the mounting cylinder 41, the mounting cylinder 41 is located between the two conveying rollers 12, and the top of the fixing member 42 is mounted on the bottom of the lifting plate 354. The fixing plate 43 is mounted on the upper part of the interior of the mounting cylinder 41, and the clamping assembly 44 is arranged at the bottom end of the fixing plate 43. A connecting rod 45 is mounted on the bottom of the clamping assembly 44, and an extrusion block 46 is mounted on the bottom end of the connecting rod 45. The shape of the extrusion block 46 is trapezoidal. A positioning assembly 47 is provided on the inner bottom wall of the mounting cylinder 41, and the positioning assembly 47 can be used to position the pallet to prevent the tire from contacting the conveying roller 12 after falling on the pallet.

[0054] like Figure 6 and Figure 7 As shown, the clamping assembly 44 includes a lifting column 441, a hinge, a clamping plate 445 and a telescopic member 446. There are multiple hinges, which are arranged at equal intervals along the length direction of the lifting column 441. Each hinge includes four hinge seats 442, four hinge plates 443 and four slide bars 444. The four hinge seats 442 are installed in a ring shape on the outside of the lifting column 441 with the axis of the lifting column 441 as the center. One end of the four hinge plates 443 is hinged to one end of the four hinge seats 442 respectively, and the other end of the four hinge plates 443 is hinged to one end of the four slide bars 444 respectively. The other end of the slide bar 444 passes through the installation tube 41 and extends to the outside of the installation tube 41.

[0055] There are four splints 445, which are located on the outside of the mounting tube 41. The sliding rod 444 is fixed to the splint 445. The telescopic member 446 is installed at the bottom end of the fixed plate 43. In this embodiment, the fixed plate 43 is a hydraulic cylinder. In other embodiments, the fixed plate 43 is a cylinder or an electric telescopic rod. The movable end of the telescopic member 446 is installed at the top of the lifting column 441, and the connecting rod 45 is installed at the bottom end of the lifting column 441.

[0056] When the lifting plate 354 moves downward, the fixing part 42 drives the mounting tube 41 to be inserted into the tire, and then the movable end of the telescopic part 446 extends out, and the lifting column 441 drives the sliding rod 444 to extend out of the mounting tube 41 through the hinge plate 443 on the hinge seat 442, so that the clamping plate 445 is away from the mounting tube 41 to clamp the tire, and then the lifting plate 354 moves upward to move the next tire to the bottom of the mounting tube 41.

[0057] When the lifting plate 354 drives the mounting cylinder 41 to move downward again, the clamped tire falls onto the unclamped tire. At this time, the telescopic member 446 drives the clamping plate 445 to approach the mounting cylinder 41 to loosen the tire, and then the mounting cylinder 41 continues to move downward. When the mounting cylinder 41 moves downward to the extreme position, the telescopic member 446 drives the clamping plate 445 to clamp the two tires and automatically align them. The above operations are repeated for subsequent tires and will not be repeated here.

[0058] like Figures 6 to 8 As shown, the positioning assembly 47 includes a rotating disk 471, a rotating rod 473 and three movable parts. The top end of the rotating rod 473 is mounted on the bottom end of the rotating disk 471, and the bottom end of the rotating rod 473 is rotatably connected to the middle part of the inner bottom wall of the mounting cylinder 41. A torque spring (not shown in the figure) is arranged between the mounting cylinder 41 and the rotating rod 473 to drive the rotating disk 471 to reset. Three limiting grooves 472 are arranged on the rotating disk 471. The limiting grooves 472 are in an arc shape. The three limiting grooves 472 are distributed in a ring array with the axis of the rotating disk 471 as the center. The three movable parts are respectively slidably arranged in the three limiting grooves 472, and the extrusion block 46 is located above the three movable parts.

[0059] Continue to refer Figures 6 to 8As shown, the movable part includes a movable rod 474, a positioning member 475, a limiting ring 476 and a protrusion 477. The positioning member 475 is located at the bottom end of the mounting tube 41, and the bottom end of the movable rod 474 is installed at the top end of the positioning member 475. The side of the positioning member 475 close to the edge of the mounting tube 41 is arc-shaped. The top end of the movable rod 474 passes through the bottom end of the mounting tube 41 and extends into the limiting groove 472. The bottom end of the mounting tube 41 is provided with a strip groove for the movable rod 474 to slide linearly. The limiting ring 476 is installed on the outside of the movable rod 474, and the bottom end of the limiting ring 476 is slidably connected to the inner bottom wall of the mounting tube 41. The protrusion 477 is installed at the top end of the movable rod 474 and is located above the rotating disk 471. A ball is provided at one end of the protrusion 477 facing the center of the rotating disk 471.

[0060] When the telescopic member 446 drives the lifting column 441 to move downward, the lifting column 441 drives the extrusion block 46 to move downward through the connecting rod 45. At this time, the extrusion block 46 can drive the positioning member 475 to move away from the center of the installation cylinder 41 through the movable rod 474 on the protrusion 477 to position the tray.

[0061] Working principle: When transporting tires, the winch 33 first drives the connecting plate 351 on the slide plate 357 to move downward through the wire rope 34, so that the installation tube 41 moves down to the limit position, and at the same time, the limit shaft 355 is inserted into the inner spline groove of the rotating shaft 225, so that the limit block 228 extends out of the bevel gear 224, and then the motor 352 drives the reciprocating screw 2 353 to rotate. When the reciprocating screw 2 353 rotates, the limit shaft 355 drives the rotating shaft 225 to rotate so that the spring in the spring box 226 accumulates force, and at the same time, the lifting plate 354 drives the installation tube 41 to move to the limit position along the length direction of the reciprocating screw 2 353.

[0062] Then, the tire is driven to move through the two guide plates 14 through the rotation of the conveying roller 12, so that the tire moves in the center. After the tire moves out of the guide plate 14, the tire is prevented from continuing to move forward through an external blocking member. Then, the installation cylinder 41 is driven to move down and inserted into the tire through the rotation of the reciprocating screw 353. At this time, the movable end of the telescopic member 446 extends out, so that the clamping plate 445 clamps the tire, and then the lifting plate 354 moves up to move the next tire to the bottom of the installation cylinder 41.

[0063] When the tire stacking is completed, the winch 33 drives the connecting plate 351 on the slide plate 357 to move upward through the wire rope 34, thereby driving the stacked tires to move upward. When the limit shaft 355 on the lifting plate 354 is disengaged from the rotating shaft 225, the limit block 228 enters the bevel gear 224. At this time, the spring in the spring box 226 is released and drives the rotating shaft 225 to rotate. At this time, the rotating shaft 225 drives the movable frame 231 on the reciprocating screw 1 222 to move through the bevel gear 1 223 on the bevel gear 224. The movable frame 231 drives the pushing plate 233 to push the pallet to move. When the movable frame 231 moves to the extreme position, the pallet moves to the bottom of the tire. At this time, the reciprocating screw 1 222 continues to rotate, driving the movable frame 231 to reset for pushing the pallet next time.

[0064] After the movable frame 231 is reset, the connecting plate 351 drives the installation cylinder 41 to move downward. During the downward movement of the installation cylinder 41, the clamping plate 445 releases the clamping of the tire, so that the tire falls onto the pallet and is still located on the outside of the installation cylinder 41. When the installation cylinder 41 moves down to the extreme position, the positioning member 475 is inserted into the hole of the pallet, and then the telescopic member 446 drives the extrusion block 46 on the connecting rod 45 to move downward through the lifting column 441, so that the positioning member 475 positions the pallet so that the axis of the hole on the pallet and the axis of the tire are located on the same straight line, thereby preventing the tire from protruding out of the pallet. After the tire is placed on the pallet, the telescopic member 446 drives the lifting column 441 to reset, and then drives the installation cylinder 41 to reset through the wire rope 34 on the winch 33, so that the tire is separated from the installation cylinder 41, so that the stacked tires can continue to be transported on the conveyor belt.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
