[0003] During the tire production process, the tire embryo needs to be moved from one device to another for operation, so the tire embryo and finished tire will undergo conventional automated operations such as grabbing and flipping during the identification and processing processes. However, nowadays, other operations are usually not possible during the flipping process, that is, after the flipping is completed, the tire is grabbed onto other equipment, which greatly increases the flipping time required, which is not conducive to the tire production efficiency. In addition, the tire flipping will also make the tire label face up or down according to demand, and now there is a lack of equipment to control the tire flipping direction, and the tire cannot be accurately flipped into a unified state.

DETAILED DESCRIPTION

[0020] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0021] like Figure 1-3As shown, it includes a gantry frame and a transport device, a flip device and a conveying device installed on the gantry frame, the flip device is located between the transport device and the conveying device, and the conveying device, the transport device and the flip device are all controlled by a travel switch to start, stop, reciprocate, rotate, etc., and the label on the tire is detected by a prior art detection device, and the flip motor 24 is controlled by the detection result to be started forward or reverse; The flipping device includes a flipping bracket 20, a flipping mounting frame 22, a flipping assembly and a clamping claw. The flipping assembly is slidably connected to the flipping mounting frame 22. The flipping assembly includes a slide plate 26 and an electric cylinder 28. The telescopic rod in the electric cylinder 28 is fixed on the slide plate 26. A cross bar is fixed in the middle of the flipping mounting frame 22. One side end face of the electric cylinder 28 is fixed on the cross bar. The slide plate 26 slides on the flipping mounting frame 22. A flipping motor 24 is fixed to one side end face of the slide plate 26. The flipping motor 24 and the clamping claw on the slide plate 26 can be driven by the electric cylinder 28 to move together, which is used to adjust the height of the clamping claw so that it can adapt to the height of the tire when the transport device transports the tire. The flipping motor 24 controls the flipping of the clamping claw. The clamping claw is installed on the flipping assembly. The clamping claw includes a clamping arm 23 and a protective roller 27. The clamping arm 23 is arranged in an arc shape and is rotatably mounted on the slide plate 26. The side away from the flip motor 24 is also connected to the flip motor 24. The flip motor 24 is used to control the rotation of the clamping arm 23 so that it can drive the tire to rotate to a horizontal state, which is convenient for the next process operation, such as logistics packaging. The protection rollers 27 are movably installed at the two side ends of the clamping arm 23, wherein at least two protection rollers 27 are arranged at each end of the clamping arm 23, and the protection rollers 27 are rotatably connected to the clamping arm 23. The material of the protection rollers 27 is one of resin and rubber. The resin is relatively soft and has a large friction force. While not damaging the tire, the tire will be clamped more firmly and not easy to fall off. At the same time, the rotatable protection rollers 27 can change the sliding friction of the clamping claws during the clamping process into rolling friction, which greatly reduces the friction force on the tire and effectively reduces the damage to the tire.

[0022] The flip mounting frame 22 moves on the flip bracket 20 through a slider 29. Two flip mounting frames 22 are provided and are symmetrically arranged. A clamping motor 25 and a flip travel motor 30 are fixedly installed on the flip bracket 20. The flip travel motor 30 is connected to the gantry frame to control the flip device to travel on the gantry frame. A lead screw 31 is connected to the flip bracket 20 for internal rotation. The clamping motor 25 and the lead screw 31 are connected by a belt. The slider 29 is installed on the lead screw 31 and is threadedly connected to the lead screw 31. The thread on the lead screw 31 is divided into two parts, and the two threads are in opposite directions. The slider 29 is controlled to move synchronously in opposite directions. The thread on the lead screw 31 can enable the flip mounting frames 22 on both sides to move inward at the same time to complete the clamping action. Moreover, the two moving speeds are the same, so that the tire can be kept in the center, which is convenient for positioning in the next process. Moreover, through the arrangement of the electric cylinder 28, the flip motor 24 and the clamping motor 25, the entire flip device has a high degree of automation, no manual intervention is required, and it can operate quickly and continuously.

[0023] The gantry frame includes a transport frame 11 and a flip frame 21. The flip bracket 20 is installed on the flip frame 21 and walks on it. The transport device is installed on the transport frame 11 and walks on it. The transport device includes a transport frame 10 that walks on the transport frame 11. An adjusting motor 13 and a transport motor 14 are fixedly installed on the top of the transport frame 10. A transport hanging shaft 12 is installed at the bottom of the transport frame 10. The transport hanging shaft 12 is controlled by the adjusting motor 13 to move up and down so that tires of different models can be transported. The transport motor 14 controls the transport frame 10 to move on the transport frame 11. The conveying device includes a conveyor belt 40. A plurality of placing tables are arranged on the conveyor belt 40. The placing tables are concave in shape and move synchronously with the conveyor belt 40. The position of the placing tables is exactly at the maximum position of the flip device moving in the direction away from the transport device.

[0024] A tire blank bidirectional turning method of the present invention is characterized by comprising the following steps: S1: The transport device takes the tire blank from other equipment in the workshop and places it on the transport hanging shaft 12, and then moves the tire blank between the clamping claws of the turning device; S2: The clamping motor 25 of the flipping device drives the clamping claw to move toward the middle to clamp the tire embryo, and then the flipping motor 24 starts the clamping claw to drive the tire to flip. The rotation direction of the clamping claw can be determined by detecting the label on the tire; S3: After the flipping is completed, the flipping travel motor 30 is started to drive the entire flipping device to move closer to the conveying device; S4: After the flipping device moves to the designated position, the placing table on the conveying device also moves synchronously to the bottom of the flipping device. At this time, the clamping claw releases the tire and the tire can be placed on the placing table. At this time, the tire blank can be transported to the next equipment in the workshop along the conveyor belt 40.

[0025] Working principle: at the beginning of operation, the transport hanging shaft 12 on the transport frame 10 removes the tire from the previous equipment, and then the transport motor 14 is used to move the transport device horizontally with the tire. When the transport frame 10 moves between the two clamping arms 23, the transport frame 10 can touch the travel switch, and the clamping motor 25 can be started at this time. The clamping motor 25 drives the lead screw 31 to rotate through the belt, and the rotation of the lead screw 31 can make the sliders 29 on both sides move inward at the same time, so that the flip mounting frame 22 drives the clamping claws to move inward and clamp the tire. After clamping the tire, the flipping travel motor 30 and the flipping motor 24 can be started at the same time. While the flipping travel motor 30 drives the tire to move, the flipping motor 24 drives the clamping arm 23 to flip the tire. The tire can be flipped during the movement of the flipping device, which greatly saves the time required for tire flipping transportation and effectively increases the tire operation efficiency.

[0026] During the process of flipping the walking motor 30 to drive the flipping device to move, the clamping arm 23 drives the tire to gradually rotate to a horizontal level, and the label on it follows the need to face up or down. When the flipping bracket 20 moves to just above the placement table, it can stop moving, and the clamping motor 25 rotates in the opposite direction to make the clamping claws loosen the tire, and the tire can fall on the placement table, and then be conveyed to the next device through the conveyor belt 40. At the same time, the flipping walking motor 30 also drives the flipping device to return. At this time, the entire process of transporting, grabbing, flipping, and transmitting the tire can be completed, and the above process can be repeated when the next tire needs to be flipped.

[0027] In summary, the tire embryo bidirectional flipping mechanism can drive the flipping motor 24 and the clamping claw on the slide plate 26 to move together through the electric cylinder 28, which is used to adjust the height of the clamping claw so that it can adapt to the height of the tire when the transportation device transports the tire; without damaging the tire, the tire will be clamped more firmly and not easy to fall off. At the same time, through the rotatable protective roller 27, the sliding friction of the clamping claw during the clamping process is changed to rolling friction, which greatly reduces the friction force on the tire and effectively reduces the damage to the tire; and through the arrangement of the electric cylinder 28, the flipping motor 24 and the clamping motor 25, the entire flipping device has a high degree of automation, no manual intervention is required, and it can operate quickly and continuously. At the same time, the tire can be flipped during the movement of the flipping device, which greatly saves the time required for tire flipping transportation and effectively increases the operation efficiency of the tire.
