AI Technical Summary
During automatic transportation, the tire embryo may fall from the air in the event of a failure, especially in high temperature environments, due to the sticky material of the rubber, the fetal claws cannot be effectively grasped, resulting in the risk of tilting or falling of the fetal embryo.
An automatic transport vehicle tire embryo anti-fall device is designed, using components such as sky rails, guide rollers, EMS carts, embryo support plates, tire grippers and anti-fall support plates. The servo motor drives the screw to open the tire gripper or Close and use mechanical springs and diffuse photoreflective sensors to ensure stable fixation of fetal embryos to prevent falling.
It effectively avoids the risk of tire embryos falling from the air during automatic transportation, ensuring the smooth operation and safe operation of the equipment.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of tire production equipment, in particular to an automatic tire embryo anti-falling device for transporting vehicles. Background Art
[0002] As we all know, EMS is the abbreviation of Engine-Management-System. EMS is currently widely used in the manufacturing industry. With the rapid development of the automatic industry, EMS is also an inevitable trend. The industrial automatic manufacturing industry benefits from the emerging direction of future development. The EMS control system processes some information in the automatic transportation process, and outputs it to the control signal after accurate calculation. It has the obvious effect of improving efficiency, saving energy and reducing consumption, saving labor costs, and promoting industrial upgrading. It has great potential for future development. Since EMS (automatic transport vehicle) automatically runs in the air, it is inevitable to have abnormal faults in the state of efficient and high-speed automatic operation. When a fault occurs, there is a risk that the tire embryo will fall from the air. In addition, since the raw material of the tire embryo is rubber, it has a certain viscosity. If the viscosity increases in the high temperature in summer, when the tire embryo is taken away by the EMS tire claw at the loading platform, the wire ring of the inner diameter of the tire embryo may not be completely grabbed, or when the tire embryo is sent to the vulcanizer loading platform, the tire embryo tilts and falls due to the stickiness during the closing process of the tire claw. Summary of the invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a tire blank anti-falling device for an automatic transport vehicle, which can promptly ensure that the equipment is in an emergency state when a fault occurs, thereby avoiding the risk of the tire blank falling from the air during the automatic transportation process.
[0004] The technical solution adopted by the utility model to solve its technical problems is: an anti-falling device for tire embryos of an automatic transport vehicle is provided, the device is provided with a ceiling rail, a vulcanization unloading platform is provided on the ground below the ceiling rail, an EMS trolley is hoisted on the ceiling rail via a guide roller, a tire embryo support plate is installed below the EMS trolley, the tire embryo support plate is a circular structure, a tire grabber is installed on the tire embryo support plate, two tire grabber claws of the tire grabber are respectively installed on the screw rod via nuts, and the end of the screw rod is connected to the output shaft of the servo motor. It is characterized in that the lower edge of each tire grabber claw is hinged with two anti-falling support plates via a rotating shaft, a proximity switch is installed above the tire grabber claw, a mechanical spring is fixed between the rotating shaft and the anti-falling support plate by screws, diffuse reflection photoelectric sensors are installed on the left and right ends of the tire grabber claw, and the diffuse reflection photoelectric sensor, the proximity switch, the servo motor and the EMS trolley are connected to the PLC controller via a signal line.
[0005] The utility model has the beneficial effect of effectively avoiding the risk of tire blanks falling from the air during the automatic transportation process, thereby ensuring the smooth operation of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0011] In the figure, the utility model is provided with a ceiling rail 1-9, a vulcanization unloading platform 1-7 is provided on the ground below the ceiling rail 1-9, a tire blank 1-6 is placed on the vulcanization unloading platform 1-7, an EMS trolley 1-1 is hoisted on the ceiling rail 1-9 via a guide roller, the EMS trolley 1-1 can slide along the ceiling rail 1-9, a tire blank support plate 2-1 is installed below the EMS trolley 1-1, the tire blank support plate 2-1 is a circular structure, a tire grabber is installed on the tire blank support plate 2-1, two tire grabber claws 1-4 of the tire grabber are respectively installed on the screw rod 1-2 via nuts, the end of the screw rod 1-2 is connected to the output shaft of the servo motor 1-3, and each tire grabber claw 1 -4 has two anti-fall support plates 1-5 hinged on the lower edge via a rotating shaft, a proximity switch 1-11 is installed above the tire grabbing claw 1-4, the rotating shaft and the anti-fall support plate 1-5 are installed with a mechanical spring 1-10 by means of screws, when the servo motor rotates, the support plate 1-5 is also opened, and the mechanical spring 1-10 installed on the support plate is also opened due to the spring tension, and diffuse reflection photoelectric sensors 1-8 are installed on the left and right ends of the tire grabbing claw 1-4, and the diffuse reflection photoelectric sensor 1-8, the proximity switch 1-11, the servo motor 1-3 and the EMS trolley 1-1 are connected to the PLC controller via signal lines.
[0012] An anti-fall support plate 1-5 is installed under the tire grabbing claw 1-4 to expand the contact area between the tire grabbing claw 1-4 and the tire embryo 1-6. The tire embryo 1-6 is transported to the designated position by the EMS trolley 1-1. Due to the stickiness of the tire embryo 1-6, it may stick to the tire grabbing claw 1-4. If the tire embryo is transported in the air, it may tilt and fall, and it will fall on the anti-fall support plate 1-5, thereby preventing the tire embryo 1-6 from falling from the air; the servo motor 1-3 is used to drive the screw 1-2 to rotate, driving the two nuts on the screw 1-2 to move in opposite directions, so that the two tire grabbing claws 1-4 of the tire grabber are opened or closed, so that the tire grabbing claws 1-4 are opened to grab the tire; the mechanical spring 1-5 is installed on the rotating shaft on the anti-fall support plate 1-5, and the servo motor 1-3 drives the support plate 1-5 to open to control the extension of the mechanical spring 1-10. The advantage of designing the tire embryo support plate 2-1 into a circular shape is that the contact area with the tire embryo 1-6 is increased.
