This is labor-intensive, occupies a large space, has low efficiency, and the tire blanks are easily damaged during the transportation process. Currently, advanced equipment has achieved robot docking of tire blank forming machines and automated logistics lines. If traditional equipment wants to use robots, the cost is high and the workload of transformation is large, which will also affect existing production capacity.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] A tire embryo swing mechanism, such as Figure 1As shown, it includes a gantry and a flipping device, the gantry is provided with an input device and an output device and the flipping device is located between the input device and the output device, and a detection device is provided on one side of the gantry. Specifically, the input device, the output device and the flipping device can all be controlled by a remote control panel to realize start, stop, reciprocation and other operations, the input device includes two input hanging shafts and the distance between the two input hanging shafts can be adjusted by the control panel, the two input hanging shafts can pass through the tire blank, lift it and convey it to the flipping device, the output device includes a conveying plate, a plurality of logistics trays are arranged in a circular array on the conveying plate and the plurality of logistics trays are arranged at intervals, and a space for accommodating the tire is formed between the plurality of logistics trays, and by arranging the logistics trays, when the tire blank is placed on the conveying plate, the logistics trays can limit the position of the tire blank to prevent the tire blank from sliding, and at the same time, an inclined surface is provided on the logistics tray, and when the tire is stationary, the tire tread contacts the inclined surface of the logistics tray, and the above-mentioned arrangement facilitates the operator to take and store the tire, thereby improving the subsequent disassembly efficiency.

[0025] The flipping device includes a base, a reduction motor, a large gear, a core shaft and a clamping assembly. Specifically, the clamping assembly includes two clamping arms and a transmission bracket. The transmission bracket is provided with a synchronous belt. The side wall of the clamping arm is provided with a driving motor. The two clamping arms are provided with two symmetrically arranged clamping shoe assemblies for fixing the tire. The two clamping arms are driven by the driving motor to realize transmission on the synchronous belt. By setting the clamping arms, when the tire is conveyed to the flipping device, the clamping arms can clamp the tire so that the input hanging shaft can be detached from the middle of the tire. At the same time, the setting of the clamping arms can prevent the tire from detaching during the rotation process, thereby ensuring the stability of the tire during the rotation process. Furthermore, a plurality of steel claws for clamping the tire are integrally formed on the clamping shoe assembly. By setting the clamping shoe assembly and the steel claws, the design of the steel claws greatly increases the clamping force between the clamping shoe assembly and the tire during the clamping process, thereby making the tire embryo more stable and reliable when fixed on the clamping arm, effectively avoiding the shaking of the tire, and the tire embryo is not easy to detach.

[0026] A connecting rod is provided on the clamping arm, and the clamping shoe assembly is rotatably connected to the connecting rod. A plurality of screw holes are provided on the clamping shoe assembly, and the clamping shoe assembly is fixed to the clamping arm by screwing bolts into the screw holes. Since the clamping shoe assembly is fastened by bolts, the bolts can ensure that the clamping shoe assembly is stable and reliable during use and is not easy to loosen. At the same time, the design of the bolts makes the disassembly and assembly process convenient and simple, and is convenient for subsequent workers to adjust the angle of the clamping shoe assembly, thereby realizing tires of more sizes. A tension spring is provided between the clamping shoe assembly and the clamping arm, and connecting columns are provided on the clamping shoe assembly and the clamping arm. The two ends of the tension spring are respectively sleeved on the two connecting columns. When the clamping shoe assembly clamps the tire, the tension spring is in a stretched state; when the equipment stops working, the tension spring can limit the clamping shoe assembly, thereby avoiding collision between the clamping shoe assembly and the clamping arm, and extending the service life of the clamping shoe assembly and the clamping arm. Furthermore, a compression spring is provided between the connecting rod and the clamping shoe assembly; when the clamping shoe assembly is fixed, the compression spring is in a compressed state; by providing the compression spring, when the tire is flipped onto the logistics pallet, the compression spring can provide a certain buffer, thereby avoiding vertical movement of the tire, protecting the tire tread from damage, and extending the service life of the equipment and the tire.

[0027] The base is provided with a cylinder for driving the clamping assembly to move horizontally toward the output device and a motor and a gear for driving the clamping assembly to rotate. Specifically, the clamping arm includes a column and a mounting seat slidably connected to the column, the mounting seat is fixed to the column by bolts, the connecting rod and the connecting column are fixedly connected to the mounting seat, and a plurality of horizontally arranged arc blocks are provided on the transmission bracket, and the arc blocks and the synchronous belt are spaced apart. By arranging a plurality of arc blocks, when the clamping arm clamps the tire, the bottom of the tire can be supported by the arc blocks, so that the tire is more stable during the clamping process, and by arranging the mounting seat and the column, the worker can adjust the position of the mounting seat, thereby reducing or increasing the distance between the two clamping shoe assemblies on the same side, so that the equipment can use more types of tires.

[0028] The transmission bracket includes a fixed part and a sliding part. The fixed part is provided with a slide rail, and a slide groove is provided at the bottom of the sliding part. The cylinder is located on one side of the slide rail and is used to drive the sliding part to slide on the slide rail. A rotating shaft is provided on the side of the fixed part close to the output device, and the fixed part is rotatably connected to the base through the rotating shaft. The design of the fixed part and the sliding part provides a stable structure that can withstand the force generated when flipping the tire and reduce failures caused by structural instability. The design of the slide rail and the slide groove reduces the friction and wear of the sliding part during movement and extends the service life of the components. By driving the sliding part to slide on the slide rail by the cylinder, precise positioning and control can be achieved, ensuring the accuracy and stability of the tire blank when flipping.

[0029] A method for turning over a tire embryo swing mechanism, characterized in that it comprises the following steps: S0: Start the equipment, start the system through the control panel, and perform a system self-check to ensure that all components are in normal working condition. At the same time, set the angle of the clamping shoe assembly, change its rotation angle on the connecting rod according to different tire blank sizes, and fix it; S1: The input device takes the tire blank from other equipment in the workshop and places it on the input hanging shaft, and then moves the tire blank toward the turning device; S2: conveying and clamping. When the tire embryo is conveyed horizontally in a vertical state to the second beam switch of the detection device, a signal is triggered. The two clamping arms move synchronously toward each other under the drive of the drive motor gear rack. The clamping shoe forms a ring to clamp the tire embryo. The steel claws on the clamping shoe assembly further fix the tire. S3: Start the motor 1, the motor 1 drives the gear to rotate and causes the clamping assembly to rotate 90 degrees around the core shaft, and the clamping assembly drives the tire blank to flip synchronously, so that the tire blank is flipped to a horizontal state; S4: Start the cylinder, which drives the clamping assembly to move toward the logistics pallet until the tire blank contacts the logistics pallet. After the tire blank contacts the logistics pallet, the travel switch is triggered, and the two clamping arms move away from each other, releasing the clamping to the maximum distance, and the cylinder retracts and moves the clamping device away from the logistics pallet. S5: Motor 1 drives the gear to rotate in the opposite direction and returns the clamping assembly to the vertical position to wait for the material, thus completing the flipping action.

[0030] Working principle: at the beginning of operation, the input hanging shaft removes the tire from the previous equipment, and then moves along the gantry 11 to the top of the flipping device, and then the clamping assembly 6 starts to work, and the driving motor 13 drives the two clamping walls to approach each other and clamp the tire. After the clamping is completed, the input hanging shaft is withdrawn, and the driving motor 13-8 is driven. The motor-8 drives the gear 9 to rotate and makes the clamping assembly 6 rotate around the core shaft. The clamping assembly 6 drives the tire embryo to flip synchronously, so that the tire embryo is flipped to a horizontal state, and then the cylinder 7 is started. The cylinder 7 drives the clamping assembly 6 to move toward the logistics tray 24 until the tire embryo contacts the logistics tray 24. After the tire embryo contacts the logistics tray 24, the travel switch is triggered, and the two clamping arms 10 move back to back, release the clamping to the maximum spacing, and the cylinder 7 retracts and makes the clamping device move back to the logistics tray 24. Then the motor-8 drives the gear 9 to rotate in the opposite direction and makes the clamping assembly 6 return to the vertical position to wait for the material, completing the flipping action. The tire moves with the conveying plate 23 and enters the next equipment in the workshop to complete the flipping process.
