Description

Technical Field

[0001] The present invention relates to the technical field of warehousing logistics loading and unloading, and in particular to a warehousing logistics loading and unloading device and method. Background Art

[0002] Warehousing logistics refers to the use of self-built or leased warehouses and sites to store, keep, load, unload, and distribute goods. The traditional definition of warehousing is given from the perspective of material storage. Modern "warehousing" is not the "warehouse" or "warehouse management" in the traditional sense, but warehousing in the context of economic globalization and supply chain integration, and warehousing in the modern logistics system. The loading and unloading of goods in warehousing logistics is particularly important.

[0003] At present, the main loading and unloading methods in warehousing logistics are: (1) manual loading and unloading: suitable for small batches and light goods, flexible operation, but low efficiency; (2) forklift loading and unloading: using forklifts to move heavy or bulk goods, high efficiency, suitable for large-scale operations; (3) lifting platform: suitable for the up and down movement of large goods, and can be loaded and unloaded at different heights; (4) conveyor belt system: used for the automatic movement of goods on a fixed route, suitable for assembly line operations, and improve efficiency; (5) gravity slide: using gravity to make the goods slide, suitable for fast loading and unloading, often used in sorting and distribution centers. Among them, manual loading and unloading, forklift loading and unloading, and lifting platform can only be loaded and unloaded at the edge, the internal cargo transportation distance is too long, and loading and unloading is inconvenient; although some conveyor belt systems and gravity slides can be loaded and unloaded internally, the angle is fixed, and can only load or unload, and the loading and unloading angle is fixed, and the applicable scenarios are limited. The conveyor belt system has a complex structure and requires a driving source. Although the gravity slide does not require a driving source, when the cargo is too heavy, the fixed loading and unloading angle can easily cause the cargo to slide down too fast, and the loading and unloading safety is poor.

DETAILED DESCRIPTION

[0036] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] Embodiment 1, as Figure 1-Figure 10As shown, a storage logistics loading and unloading equipment includes a loading and unloading vehicle 1, two groups of upper guide frames 2 are fixedly installed on the top of the loading and unloading vehicle 1, an arc-shaped guide groove 21 is opened inside the upper guide frame 2, the center of the arc-shaped guide groove 21 is on the same horizontal plane as the bottom of the vehicle compartment, a slider 3 is slidably connected inside the arc-shaped guide groove 21, a connecting shaft 4 is fixedly installed between the two groups of sliders 3, an outer frame plate 31 is arranged on the outer side of the slider 3, the outer frame plate 31 can be locked on the upper guide frame 2, a hydraulic cylinder 32 is fixedly installed on the bottom of the front outer frame plate 31, a pressure sensor 33 is fixedly installed on the top of the hydraulic cylinder 32, and a driving gear rod 34 is fixedly installed on the top of the pressure sensor 33;

[0038] A conveying frame 5 is rotatably mounted on the outer side of the connecting shaft 4, and a plurality of conveying rollers 51 are rotatably mounted inside the conveying frame 5. A baffle plate 52 is arranged on the left side of the conveying frame 5, and a bottom frame 6 is hingedly connected to the bottom of the baffle plate 52, and the bottom frame 6 can be locked on the baffle plate 52. A flip wheel 54 is fixedly mounted on the outer side of the rotating center of the conveying frame 5, and the flip wheel 54 is meshed with the driving gear rod 34.

[0039] It also includes a positioning plug 7, which is composed of two groups of clamps. Through this design, the positioning plug 7 can clamp the thickness of the car floor. An adjusting slot 72 is provided inside the positioning plug 7, and a hinge shaft 74 is inserted inside the adjusting slot 72. The hinge shaft 74 can be locked on the positioning plug 7. The hinge shaft 74 is rotatably installed on the top of the conveying frame 5, and a torsion spring is provided between the hinge shaft 74 and the conveying frame 5. An angle sensor 55 is fixedly installed on the outer side of the conveying frame 5, and the angle sensor 55 is connected to the hinge shaft 74.

[0040] Loading: Push the loading and unloading vehicle 1 so that it approaches the carriage, and the loading and unloading vehicle 1 is located on the left side of the carriage, the conveying frame 5 is located on the left side of the loading and unloading vehicle 1, and the conveying frame 5 is in a vertical state, and the bottom frame 6 is located at the bottom. When conveying a small amount and large goods, the goods are stacked on the bottom frame 6, and then the hydraulic cylinder 32 is controlled to operate, the hydraulic cylinder 32 drives the driving gear rod 34 to rise, the driving gear rod 34 drives the flip wheel 54 to rotate, and the flip wheel 54 drives the conveying frame 5 to swing to the right. During the swinging process, the goods are lifted by the conveying frame 5, and the pressure sensor 33 detects the gravity of the goods. The loading and unloading vehicle 1 has a built-in controller, which can automatically calculate the conveying angle according to the gravity of the goods. When the conveying frame 5 swings 70 degrees to the right, the rotation center of the hinge shaft 74 is located on the center of the arc guide groove 21, and the bottom of the carriage and the center of the arc guide groove 21 are on the same horizontal plane, and then push When the equipment moves, the positioning plug 7 and the conveying frame 5 are in the same straight line under the action of the torsion spring, and the positioning plug 7 opens obliquely upward. The positioning plug 7 can be inserted into the bottom plate of the carriage by directly pushing the equipment, and the positioning plug 7 drives the hinge shaft 74 to swing relative to the conveying frame 5. As the hydraulic cylinder 32 continues to be controlled to operate, the right end of the conveying frame 5 cannot swing downward under the restriction of the positioning plug 7. Therefore, when the conveying frame 5 continues to swing downward, it will drive the slider 3 to swing upward along the arc guide groove 21, so that the conveying frame 5 swings to the left end higher than the right end. According to the feedback of the rotation angle of the hinge shaft 74 by the angle sensor 55, that is, the angle between the positioning plug 7 and the conveying frame 5, when the angle reaches the calculated angle, the hydraulic cylinder 32 stops running. At this time, the goods automatically slide into the carriage at a safe speed under the action of gravity, and the loading and unloading safety is high. The operation process of the equipment during the loading and unloading of large goods is attached Figure 1 To Attachment Figure 8 Then to the attached Fig. 9 ;

[0041] When transporting goods of light weight and large quantity, the left end of the conveying frame 5 is made higher than the right end. The conveying frame 5 is set between the goods and the carriage and can be transported directly by gravity. When loading the interior, first push the device away from the carriage, and then adjust the positioning plug 7. The positioning plug 7 rises relative to the hinge shaft 74 so that the rotation center of the hinge shaft 74 can be in the same straight line with the bottom surface of the positioning plug 7. Then push the device close to the carriage and manually swing the positioning plug 7 to a horizontal position. The bottom of the positioning plug 7 enters the carriage along the bottom of the carriage. At this time, push the device, and the positioning plug 7 moves in a straight line along the bottom of the carriage. The rotation center of the positioning plug 7 is always located at the center of the arc guide groove 21. The goods can directly enter the interior of the carriage through the conveying frame 5. At this time, when the hydraulic cylinder 32 is controlled to operate, the tilt angle of the conveying frame 5 can be controlled, so that the goods can be transported to the interior of the carriage at a desired angle, as shown in the attached figure. Fig.10After the internal loading is completed, the device is pulled outward, and then the positioning plug 7 is lowered, and then the positioning plug 7 is inserted into the bottom plate of the carriage to carry out edge loading. By adjusting the positioning plug 7 upward and downward, the center of the hinge shaft 74 can always be on the same plane as the bottom of the carriage. Whether it is internal loading or edge loading, the angle of the conveyor frame 5 can be stably adjusted;

[0042] When unloading: push the equipment close to the carriage, then control the hydraulic cylinder 32 to operate, the hydraulic cylinder 32 drives the conveyor frame 5 to swing 70 degrees to the right, and then push the equipment to move, so that the positioning plug 7 is inserted into the bottom plate of the carriage, and the goods are moved to the conveyor frame 5 to complete the edge unloading. After the edge unloading, as the hydraulic cylinder 32 continues to be controlled to operate, the conveyor frame 5 drives the slider 3 to swing upward along the arc guide groove 21 under the restriction of the positioning plug 7, so that the conveyor frame 5 swings to the horizontal, and then inserts it into the carriage. After the goods are moved to the conveyor frame 5, pull the equipment outward and make the conveyor frame 5 swing downward to complete the internal unloading.

[0043] It should be noted that the upper guide frame 2, the conveying frame 5, the bottom frame 6 and the positioning plug 7 of the present invention are all made of aluminum alloy, the conveying roller 51 is a clinker roller, and the device is light in weight.
