Description

Technical Field

[0001] The utility model relates to the technical field of tire production equipment, in particular to a tire swing cart device. Background Art

[0002] After the tire embryo is produced, it needs to be stored in a three-dimensional shelf before vulcanization for subsequent use during vulcanization. However, it is obviously unrealistic to manually carry the embryo onto the three-dimensional shelf, and it is also inefficient to carry them one by one with a crane. Therefore, enterprises generally use a manipulator to grab and stack the embryos on the conveyor belt onto the three-dimensional shelf. The embryos on the three-dimensional shelf are taken out by a stacker and sent out of the warehouse through a conveyor line to the vulcanizer.

[0003] However, when the embryo is conveyed from the conveyor belt to the manipulator, due to the uncertain position of the embryo on the conveyor belt, it is easy to cause inaccurate grasping position of the manipulator, or even failure to grasp the embryo. In the lightest case, the embryo will fall, and in the worst case, the embryo will be damaged, resulting in deformation of the raw tire and appearance of defective products, which brings inconvenience to the streamlined production. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: in order to overcome the deficiency that due to the uncertain position of the embryo on the conveyor belt in the prior art, it is easy to cause inaccurate grasping position of the manipulator, or even failure to grasp the embryo, the utility model provides a tire swing cart device.

[0005] The technical solution adopted by the utility model to solve its technical problem is: a tire swing cart device, including a tire production line arranged on a frame. A centering mechanism is arranged at the front side of the production line, and a limiting mechanism is arranged at the rear side of the production line. A rail car is arranged between the centering mechanism and the limiting mechanism. A lifting cylinder is arranged on the rail car, and a horizontally arranged cross-shaped lifting plate is arranged at the output end of the lifting cylinder.

[0006] The centering mechanism includes a roller machine arranged at the end of a conveyor belt. A cross-shaped lifting port cooperating with the cross-shaped lifting plate is arranged at the end of the roller machine. A centering component is arranged above the roller machine for aligning the center of the tire with the center of the cross-shaped lifting port.

[0007] The limiting mechanism includes a plurality of brackets arranged in sequence along the conveying direction of the production line. An embryo support for cooperating with the inner ring of the tire is arranged on each bracket. The embryo support on each bracket corresponds to a tire of a specific specification. A cross-shaped avoidance port cooperating with the cross-shaped lifting plate is arranged on the bracket and the embryo support, and the center of each embryo support is aligned with the center of the cross-shaped avoidance port.

[0008] The conveyor belt is used to convey the tire to the drum machine, and the centering component is used to correct the position of the tire arranged on the drum machine so that the center of the tire is aligned with the center of the cross-shaped lifting port; when the rail trolley is arranged below the centering mechanism, the cross-shaped lifting plate corresponds to the position of the cross-shaped lifting port, and when the rail trolley is arranged below the limiting mechanism, the cross-shaped lifting plate corresponds to the position of the cross-shaped avoidance port; after the tire position is corrected, the rail trolley moves below the centering mechanism (i.e., below the tire), the output end of the lifting cylinder on the rail trolley extends, so that the cross-shaped lifting plate passes through the cross-shaped lifting port to lift the tire, and then the rail trolley moves towards the limiting mechanism. When the rail trolley moves below the limiting mechanism, the cross-shaped lifting plate and the tire are arranged above the embryo support, the output end of the lifting cylinder contracts, so that the position of the cross-shaped lifting plate drops, the tire falls on the bracket, and the embryo support is lined inside the tire.

[0009] Further, in order to correct the position of the tire arranged on the drum machine, the centering component includes two roller groups symmetrically arranged with the center of the cross-shaped lifting port as the center. Each roller group includes two U-shaped frames arranged in a V shape, and a row of vertically arranged rollers are arranged on the U-shaped frames. A driving component for driving the two roller groups to approach or move away synchronously is arranged on the two roller groups.

[0010] The two roller groups include four U-shaped frames. When the driving component drives the two roller groups to approach each other, the rollers on the four U-shaped frames squeeze the outer peripheral wall of the tire, and finally center the position of the tire. Then the two roller groups move away from each other to loosen the tire, which is convenient for the cross-shaped lifting plate to lift the tire from the drum machine.

[0011] Further, in order to drive the two roller groups to approach or move away synchronously, so as to realize the centering action of the tire, the driving component includes a vertical frame arranged above the drum machine. Two slide rails arranged along the width direction of the drum machine are arranged on the vertical frame. Slide tables are slidably arranged on the two slide rails. A moving rod is arranged on the two slide tables. Connecting rods for connecting two U-shaped frames in the same roller group are arranged at both ends of the moving rod. Rack teeth are arranged on one side of the two slide tables close to each other. A central gear meshing with the two rack teeth is arranged between the two rack teeth. The central gear is rotatably connected with the vertical frame.

[0012] Further, a cylinder parallel to the axis of the slide rail is arranged on the vertical frame. The cylinder block of the cylinder is fixedly connected with the vertical frame, and the output end of the cylinder is fixedly connected with one of the slide tables or the moving rod.

[0013] Further, in order to ensure that the rail trolley stably conveys the centered tire to the tire embryo support and prevent the tire from shifting during the movement of the rail trolley, two guide rails are arranged in parallel along the production line conveying direction on the frame. The rail trolley is provided with V-shaped guide wheels that cooperate with the guide rails. The two ends of the frame are rotatably connected with a driving wheel and a driven wheel, and a synchronous belt for driving the rail trolley to reciprocate on the guide rails is wound around the driving wheel and the driven wheel.

[0014] Further, in order to prevent the cross-shaped lifting plate from deforming during long-term use, linear bearings are arranged on both sides of the lifting cylinder where the rail trolley is located. A support rod is arranged inside the linear bearing, and the upper end of the support rod is fixedly connected to the cross-shaped lifting plate.

[0015] The beneficial effects of the present utility model are as follows: A tire swing vehicle device provided by the present utility model adopts a rail trolley to move back and forth between a centering mechanism and a limiting mechanism at fixed points. After the centering mechanism corrects the position of the tire, the rail trolley accurately lifts and places the tire into the limiting mechanism, making the position of the tire unique, ensuring that the manipulator can accurately grasp the tire and stack it on the shelf, avoiding damage to the tire, and improving production efficiency and production quality.

[0026] The centering mechanism 2 includes a drum machine 21 provided at the end of a conveyor belt. A cross-shaped jacking port 212 that cooperates with the cross-shaped jacking plate 42 is provided at the end of the drum machine 21. A centering component for aligning the center of the tire with the center of the cross-shaped jacking port 212 is provided above the drum machine 21.

[0027] The limiting mechanism 3 includes a plurality of brackets 31 arranged in sequence along the conveying direction of the production line. A tire embryo support 32 for cooperating with the inner ring of the tire is provided on each bracket 31. The tire embryo support 32 on each bracket 31 corresponds to a tire of a specific specification. A cross-shaped avoidance port 33 that cooperates with the cross-shaped jacking plate 42 is provided on the bracket 31 and the tire embryo support 32. The centers of the tire embryo supports 32 are aligned with the centers of the cross-shaped avoidance ports 33. The tire embryo support 32 is composed of four support blocks whose outer wall surfaces are on the same cylindrical surface. Infrared sensors for sensing the cross-shaped jacking plate 42 are provided at the cross-shaped jacking port 212 on the frame 1 and at each cross-shaped avoidance port 33.

[0028] The centering component includes two roller groups symmetrically arranged with respect to the center of the cruciform jacking opening 212. Each roller group includes two U-shaped frames 22 arranged in a V-shape. A row of vertically arranged rollers 221 is provided on the U-shaped frame 22. A driving component is provided on the two roller groups for driving the two roller groups to approach or move away from each other synchronously.

[0029] The driving component includes a vertical frame 23 provided above the drum machine 21. Two slide rails 24 are arranged on the vertical frame 23 along the width direction of the drum machine 21. Slide tables 25 are slidably arranged on the two slide rails 24. A moving rod 26 is provided on the two slide tables 25. Connecting rods 261 for connecting two U-shaped frames 22 within the same roller group are provided at both ends of the moving rod 26. Rack bars 27 are provided on one side of the two slide tables 25 close to each other. A central gear 28 meshing with the two rack bars 27 is provided between the two rack bars 27. The central gear 28 is rotatably connected to the vertical frame 23. A cylinder 29 parallel to the axis of the slide rail 24 is provided on the vertical frame 23. The cylinder block of the cylinder 29 is fixedly connected to the vertical frame 23. The output end of the cylinder 29 is fixedly connected to one of the moving rods 26.

[0030] Two guide rails 45 are arranged in parallel on the frame 1 along the conveying direction of the production line. V-shaped guide wheels 46 cooperating with the guide rails 45 are provided on the rail trolley 4. A driving wheel 47 and a driven wheel 48 are rotatably connected to both ends of the frame 1. A synchronous belt 49 for driving the rail trolley 4 to reciprocate on the guide rail 45 is wound around the driving wheel 47 and the driven wheel 48.

[0031] Working process:

[0032] The tire is placed flat on the conveyor belt for conveying. When the tire is conveyed onto the drum machine 21, the cylinder 29 contracts to apply a force to one of the moving rods 26. Under the cooperation of the central gear 28 and the two rack bars 27, the two moving rods 26 move synchronously towards each other through the slide tables 25 on the slide rails 24, thereby driving the four U-shaped frames 22 of the two roller groups to approach each other in pairs. The rollers 221 on the four brackets 31 squeeze the outer peripheral wall of the tire, and finally center the position of the tire, so that the center of the tire is aligned with the center of the cruciform jacking opening 212.

[0033] Generally, only one specification of tire is processed in one batch. Just turn on the infrared sensors at the corresponding specification tire embryo supports 32, and turn off the infrared sensors at the other specification tire embryo supports 32. Then, when the cruciform jacking plate 42 passes through the infrared sensors in the open state, the rail trolley 4 will stop moving.

[0034] When the output end of the lifting cylinder 41 is fully extended, the cross-shaped lifting plate 42 jacks up the tire placed on the roller machine 21 to separate it from the surface of the roller machine 21. At this time, the height of the cross-shaped lifting plate 42 is higher than the upper end surface of the tire embryo support 32. Subsequently, the rail trolley 4 carries the tire and moves it to the position below the cross-shaped avoidance opening 33 of the corresponding specification tire embryo support 32. The cross-shaped lifting plate 42 and the tire are located above the tire embryo support 32. The output end of the lifting cylinder 41 contracts, causing the position of the cross-shaped lifting plate 42 to drop, and the tire falls onto the support 31. The tire embryo support 32 is lined inside the tire, making the position of the tire unique. Finally, the rail trolley 4 returns to the position below the cross-shaped lifting opening 212 of the roller machine 21 to wait for the next tire handling.
