Description

Technical Field

[0001] This utility model relates to the field of automated loading and unloading equipment technology, and more specifically, to a container loading and unloading device. Background Technology

[0002] With the continuous development of computer vision and machine learning technologies, as well as the emergence of various high-precision sensors, semi-automatic manual loading and unloading methods are gradually being replaced by fully automated loading and unloading robots. These robots typically have container loading and unloading devices at their execution end for gripping or stacking goods. Containers are transported via conveyor belts on these devices. Some conveyor belts have baffles on the sides to prevent containers from falling off, but these baffles are usually fixed and cannot be dynamically adjusted according to the needs of the transportation process. This results in a low level of automation and consequently, low accuracy in container transport. Utility Model Content

[0003] This invention aims to overcome the problem of low accuracy in container conveying during loading and unloading in the prior art by providing a container loading and unloading device.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a box loading and unloading device, comprising: a frame, on which a transmission mechanism for conveying boxes is connected, and swing arm mechanisms are provided on both sides of the transmission mechanism. The swing arm mechanism includes a swing arm drive component, a swing arm transmission assembly, and a swing arm baffle. The fixed end of the swing arm drive component is fixedly connected to the frame, and the output end of the swing arm drive component is drively connected to the swing arm transmission assembly. The output end of the swing arm transmission assembly is connected to the swing arm baffle to drive the swing arm baffle to move laterally along the transmission mechanism.

[0005] In the technical solution of this utility model, by setting a swing arm mechanism on the transmission mechanism, the swing arm drive component drives the swing arm baffle to move laterally through the swing arm transmission assembly. On the one hand, the passage path of the box on the transmission mechanism can be limited, so that the box can be transported out from a suitable loading and unloading position. On the other hand, when the box passes through the transmission mechanism, the swing arm drive component can adjust the swing arm baffle to push the box to move, thereby dynamically adjusting the position of the box on the transmission mechanism to facilitate loading and unloading of the box.

[0006] Furthermore, the swing arm baffle includes a first baffle and a second baffle, the first baffle is connected to the swing arm transmission assembly, and the second baffle is adjustablely connected to the first baffle along the conveying direction of the transmission mechanism.

[0007] In this solution, the length of the swing arm baffle can be adjusted by changing the connection length between the first baffle and the second baffle to suit the conveying needs of different boxes.

[0008] Furthermore, the first baffle is provided with a plurality of rollers along the length direction of the transmission mechanism, and the second baffle is slidably connected to the first baffle and in rolling contact with at least a portion of the rollers.

[0009] In this design, rollers are used to facilitate the adjustment of the second baffle.

[0010] Furthermore, the swing arm transmission assembly includes a parallelogram mechanism, which includes a fixed rod fixedly connected to the frame. Two rocker arms are rotatably connected to the two ends of the fixed rod. The swing arm baffle, as a connecting rod of the parallelogram mechanism, is rotatably connected to the rocker arms at both ends. The output end of the swing arm drive is connected to the rocker arms to drive the rocker arms to swing.

[0011] In this solution, a parallelogram mechanism is used to facilitate the movement of the swing arm baffle, which is more compact and has better stability compared to conventional telescopic mechanisms.

[0012] Furthermore, the swing arm transmission assembly also includes a first reinforcing rod and a second reinforcing rod. The rocker arm has a groove along its length, and a slider is slidably connected in the groove. One end of each pair of first reinforcing rods is rotatably connected to the fixed rod, and the other end of each pair of first reinforcing rods is rotatably connected to the slider on the corresponding side. Both ends of the second reinforcing rod are rotatably connected to the sliders on both sides. The fixed rod, the first reinforcing rod and the second reinforcing rod are connected to form a parallelogram.

[0013] In this solution, by setting a first reinforcing rod and a second reinforcing rod, the normal movement of the parallelogram mechanism is not affected, and the parallelogram mechanism can be provided with auxiliary support, so that the swing arm mechanism can maintain structural stability when pushing the box.

[0014] Furthermore, the transmission mechanism is provided with a gripping mechanism, which includes multiple conveyor belts arranged along the conveying direction of the box. The conveyor belts are spaced apart to form a receiving space for accommodating the gripping mechanism, which can extend from the receiving space to grip the box.

[0015] In this solution, when the loading and unloading device is in the loading state, the container is sent from the transmission mechanism to the cargo box. At this time, the gripping mechanism can be retracted into the receiving space without affecting the transmission mechanism from sending the container in. When the loading and unloading device is in the unloading state, the gripping mechanism can extend from the receiving space and grab the container onto the transmission mechanism. Then the gripping mechanism is retracted into the receiving space without affecting the transmission mechanism from sending the container out.

[0016] Furthermore, it also includes a first box-pushing mechanism, the fixed end of which is connected to the frame, and the movable end of which can extend out of the front end of the transmission mechanism and move laterally along the transmission mechanism to push the boxes leaving the transmission mechanism to press together.

[0017] In this solution, during packing, the first box-pushing mechanism can move laterally to press the boxes that have left the conveying mechanism together, thereby making full use of the space inside the box for packing.

[0018] Furthermore, the first box-pushing mechanism includes a first box-pushing drive component, a first box-pushing transmission assembly, and a first push plate. The fixed end of the first box-pushing drive component is fixedly connected to the frame, the output end of the first box-pushing drive component is drively connected to the first box-pushing transmission assembly, and the output end of the first box-pushing transmission assembly is connected to the first push plate to drive the first push plate to move.

[0019] In this solution, during the packing process, the first pusher drive unit transmits power to the first pusher transmission assembly, thereby driving the first pusher plate to move and press the box body together.

[0020] Furthermore, it also includes a second box-pushing mechanism, the fixed end of which is connected to the frame, and the movable end of which can extend out of the front end of the transmission mechanism and move along the length of the transmission mechanism to push the boxes together.

[0021] In this solution, during packing, the second box-pushing mechanism can press the boxes that have left the conveying mechanism together along the length direction, thereby making full use of the space inside the box for packing.

[0022] Furthermore, the second push box mechanism includes a second push box drive component, a second push box transmission assembly, and a second push plate. The fixed end of the second push box drive component is fixedly connected to the frame, the output end of the second push box drive component is drively connected to the second push box transmission assembly, and the output end of the second push box transmission assembly is connected to the second push plate to drive the second push plate to move.

[0023] In this solution, the second push box drive component is transmitted to the second push box transmission assembly, thereby driving the second push plate to move and push the box body to press.

[0024] Compared with the prior art, the beneficial effects of this utility model are: I. The container loading and unloading device of this utility model, by setting a swing arm mechanism on the transmission mechanism, uses a swing arm drive component to drive the swing arm baffle to move laterally through the swing arm transmission assembly.

On the other hand, when the container passes through the transmission mechanism, the swing arm drive component can adjust the swing arm baffle to push the container to move, thereby dynamically adjusting the position of the container on the transmission mechanism to facilitate loading and unloading of the container.

[0025] II. In the case of the container loading and unloading device of this utility model, when the loading and unloading device is in the loading state, the container is sent from the transmission mechanism to the cargo box. At this time, the gripping mechanism can be stored in the receiving space without affecting the transmission mechanism from sending the container in. When the loading and unloading device is in the unloading state, the gripping mechanism can extend from the receiving space and grab the container onto the transmission mechanism. Then the gripping mechanism is stored in the receiving space without affecting the transmission mechanism from sending the container out.

[0026] III. The container loading and unloading device of this utility model is provided with a first box pushing mechanism and a second box pushing mechanism. After the container leaves the transmission mechanism from the end of the conveying mechanism, it can be further pushed along the length direction and the lateral direction by the first box pushing mechanism and the second box pushing mechanism to stack the containers, so that the containers are pressed together to reduce the gap, thereby making full use of the space inside the container for loading.

[0032] In this embodiment, by setting a swing arm mechanism 4 on the transmission mechanism 2, the swing arm drive 41 drives the swing arm baffle 43 to move laterally through the swing arm transmission assembly 42. On the one hand, the passage path of the box on the transmission mechanism 2 can be limited, so that the box can be transported out from a suitable loading and unloading position. On the other hand, when the box passes through the transmission mechanism 2, the swing arm drive 41 can adjust the swing arm baffle 43 to push the box to move, thereby dynamically adjusting the position of the box on the transmission mechanism 2 to facilitate loading and unloading of the box.

The first baffle 431 is connected to the swing arm transmission assembly 42, and the second baffle 432 is adjustablely connected to the first baffle 431 along the conveying direction of the transmission mechanism 2.

[0034] In this embodiment, the length of the swing arm baffle 43 can be adjusted by changing the connection length of the first baffle 431 and the second baffle 432 to suit the conveying needs of different boxes. The end of the second baffle 432 furthest from the first baffle 431 can be arc-shaped, with the arc-shaped end facing the direction from which the box arrives, thus guiding the box into the designated position.

In this embodiment, the rollers 433 are provided to facilitate the adjustment of the second baffle 432.

[0036] refer to Figure 2The swing arm transmission assembly 42 includes a parallelogram mechanism. The parallelogram mechanism includes a fixed rod 421 fixedly connected to the frame 1. Two rocker arms 422 are rotatably connected to both ends of the fixed rod 421. The swing arm baffle 43, acting as a connecting rod of the parallelogram mechanism, is rotatably connected to the rocker arms 422 at both ends. The output end of the swing arm drive component 41 is driveably connected to the rocker arms 422 to drive them to swing.

[0040] Taking the loading and unloading of containers inside a cargo container as an example, regardless of whether the container is being loaded or unloaded, the loading and unloading device is located inside the cargo container and connected to external transportation via other conveying structures. Loading refers to the loading and unloading device sequentially placing containers, which are fed into the cargo container by other conveying structures, into the cargo container. Unloading refers to the loading and unloading device sequentially removing the stacked containers from the cargo container and sending them out of the cargo container via other conveying structures.

[0041] In this embodiment, when the loading and unloading device is in the loading state, the container is sent from the transmission mechanism 2 into the cargo box.

When the loading and unloading device is in the unloading state, the gripping mechanism 3 can extend from the receiving space and grip the container onto the transmission mechanism 2. Then, the gripping mechanism 3 is retracted into the receiving space without affecting the transmission mechanism 2 from sending the container out.

The gripping linkage assembly 33 is a parallelogram mechanism, including a fixed rod, a pair of swing arms, and an intermediate connecting rod. The fixed rod is fixedly connected to the frame 1, and the intermediate connecting rod is fixedly connected to the suction cup 34.

Each accommodating space is equipped with a gripping mechanism 3, and the moving ends of the gripping linkage assembly 33 of each gripping mechanism 3 are connected by a synchronization rod. By connecting multiple gripping mechanisms 3 through the synchronization rod, the synchronous gripping actions of multiple gripping mechanisms 3 are realized.
