Description

Technical Field

[0001] The invention relates to a catenary system loading and unloading transfer and docking mechanism and an application method thereof, belonging to the technical field of conveying equipment. Background Art

[0002] Suspension conveyor chains, short for suspension conveyor chains, utilize ball bearings as chain wheels, allowing them to turn and climb freely and adapt to various geographical conditions. Suspension conveyor chains allow for flexible conveying routes, effectively utilize space, save manpower, and improve efficiency. They primarily consist of chains, tracks, slings, brackets, drive seats, and adjustment seats. Suspension conveyor chains are widely used in high-volume assembly line production in industries such as machinery, automobiles, electronics, household appliances, light industry, food, and chemicals. They utilize multiple aerial delivery points and adjustable conveying speeds to transport workpieces, making them highly advantageous for mechanical assembly operations. They are a popular conveyor system used by domestic enterprises.

[0003] Traditional logistics suspension chains have long been widely used due to their low cost and operating expenses. For many years, loading and unloading materials from suspension chains was labor-intensive, and as wages rose, operating costs also continued to rise. The suspension chain-AGV docking device, leveraging IoT technology, solves this problem of automated material loading and unloading, saving labor and reducing production costs for enterprises, bringing convenience to the automation and integration of logistics production.

[0004] However, in current practical applications, the shaking of the material tooling when running on the catenary can easily cause docking errors when docking with the AGV trolley at the loading and unloading joints, resulting in loading and unloading failures or even line stoppages. At the same time, loading and unloading require special AGV docking, which increases equipment occupancy costs. Summary of the Invention

[0006] The present invention proposes a technical solution to solve the above technical problems: a catenary system loading and unloading transfer docking mechanism, comprising two symmetrically arranged transverse closing devices, the transverse closing devices comprising a correction cylinder, a base and a transverse slide, the transverse slide being arranged at the upper end of the base for transverse sliding, and the correction cylinder being arranged near the transverse slide for driving the transverse slide to slide transversely;

[0007] A longitudinal sliding device is provided at the upper end of the transverse slide, and the longitudinal sliding device includes a longitudinal slide and a propulsion cylinder. The longitudinal slide is provided at the upper end of the transverse slide and can slide longitudinally. The propulsion cylinder is provided near the longitudinal slide and is used to drive the longitudinal slide to slide longitudinally.

[0008] A lifting device is provided at the upper end of the longitudinal slide, which includes a lifting cylinder, a lifting slider and a material support plate. The lifting slider can slide up and down on the outer wall of the cylinder of the lifting cylinder, and the upper end of the material support plate is fixedly connected to the outer side wall of the lifting slider.

[0009] The improvement of the above technical solution is that positioning devices are symmetrically arranged at both ends of the material support plate in the length direction, the positioning device includes a positioning cylinder and a positioning rod, the positioning rod includes a positioning part and a driving part, and a hinged through hole is opened at the junction of the positioning part and the driving part of the positioning rod. The positioning rod is hinged to the material support plate through the hinged through hole, the positioning cylinder is arranged at the lower end of the material support plate, and the output shaft of the positioning cylinder is hinged to the driving part of the positioning rod.

[0010] The improvement of the above technical solution is that: long strip openings suitable for the positioning part of the positioning rod to pass through are opened at both ends of the material support plate in the length direction.

[0011] The improvement of the above technical solution is that: the base of the horizontal closing device is two and symmetrically arranged, and a first linear guide rail is arranged on the upper end of the base along its length direction. The two ends of the horizontal slide can be laterally slidable at the upper end of the first linear guide rail through the horizontal slider.

[0012] The improvement of the above technical solution is: a second linear guide rail is set at the upper end of the horizontal slide along its length direction, and the longitudinal slide device has two longitudinal slides, which can be longitudinally slidable at the upper end of the second linear guide rail through the longitudinal slider.

[0013] The improvement of the above technical solution is that the lifting device has two lifting cylinders, which are respectively arranged on the upper ends of the two longitudinal slides, and the upper ends of the material support plate are respectively fixed to the outer side walls of the lifting slides of the two lifting cylinders.

[0014] The improvement of the above technical solution is: a cable protection drag chain and a drag chain mounting groove are provided at the upper end of the horizontal slide, the drag chain mounting groove is fixedly connected to the upper end of the horizontal slide, one end of the cable protection drag chain is fixedly connected to the upper end of a lifting cylinder of the lifting device, and the other end of the cable protection drag chain is fixedly connected to the end of the drag chain mounting groove away from the lifting cylinder.

Start the positioning cylinders at both ends of the material support plates on both sides respectively, control the output shafts of the positioning cylinders to extend, and the output shafts of the positioning cylinders drive the driving part of the positioning rod to rotate along the hinged through-hole, thereby driving the positioning part of the positioning rod to stand upright. The positioning part of the positioning rod corrects the longitudinal deviation of the material tooling;

[0020] D. Open positioning holes at both ends of the material pallet in the longitudinal direction, and set conical positioning feet at the lower end of the material tooling corresponding to the positioning holes. Activate the lifting cylinders of the lifting devices on both sides respectively to control the material pallet on the lifting cylinder to rise and lift the material tooling. The positioning holes on the material pallet align with the conical positioning feet of the material tooling.

The material support plate lifts the material tooling and separates it from the hook of the catenary system. Control the propulsion cylinders on both sides to retract, completing the unloading action;

[0027] d. Control the AGV trolley to enter the docking position between the two horizontal closing devices, control the material pallet on the jacking cylinder to descend, and place the material tooling on the AGV trolley;
