Description

Technical Field

[0001] The utility model belongs to the technical field of cargo loading and unloading, and particularly relates to a loading and unloading device. Background Art

[0002] Vans are currently the main means of transport for road freight. There are two main methods of loading and unloading cargo on trucks: manual loading and unloading and loading and unloading by loading and unloading machines. Manual loading and unloading not only increases labor costs, but also poses a greater safety risk due to the harsh working environment. Compared to manual loading and unloading, mechanized automatic loading and unloading systems can reduce the workload of workers during loading and improve the efficiency of loading cargo. Currently, automatic loading and unloading systems are mainly used in fenced-type trucks. Since fenced-type trucks have an open top, they often use a top-drop method for automatic loading, which is more efficient. However, this is not suitable for vans with rear doors. Existing automatic loading and unloading systems for rear-door trucks mostly require transport to the truck compartment for palletizing, which takes a long time to load and unload, resulting in low efficiency.

[0033] Van trucks are currently the primary mode of highway freight transportation in my country. There are two main methods for loading and unloading cargo on trucks: manual loading and unloading and loading and unloading machines. Manual loading and unloading not only increases labor costs but also presents a harsh working environment and significant safety risks. Compared to manual loading and unloading, mechanized automatic loading and unloading systems can reduce the workload of workers during loading and improve loading efficiency. Currently, automatic loading and unloading systems are primarily used for fenced-type trucks. Because fenced-type trucks have an open top, they often use a top-drop method for automatic loading, which is highly efficient. However, this is not suitable for rear-door van trucks. Existing automatic loading and unloading systems for rear-door vans generally require palletizing after transporting the cargo to the truck bed, resulting in lengthy loading and unloading times and low efficiency. Currently, most existing loading and unloading systems focus on the loading phase, while systems for the unloading phase are less well-researched and less mature.

[0034] Existing methods for implementing loading and unloading machine systems are primarily based on rail transport. There are numerous methods for loading and unloading vans. One is the loading method, whereby workers use a forklift or manual labor to place the goods onto a horizontal conveyor row. A motor drives the conveyor row, moving the goods forward to the front baffle. The worker then continues to stack the goods onto the horizontal conveyor row until the goods are fully stacked. A hydraulic lift cylinder adjusts the conveyor row to the same height as the floor of the van. A push motor drives a sprocket and a push chain to push the conveyor row, carrying the goods, onto the conveyor row chassis, to the front of the van. A blocking motor drives a baffle plate to block the goods. The push motor then reverses, driving the sprocket to reverse, ultimately pulling the conveyor row out of the van. The horizontal conveyor row continues to push the goods forward, ensuring the goods are kept forward without being pulled out of the van. This method is only suitable for loading and is not suitable for unloading. The system is bulky, the conveyor row is long, and the stability of the cargo stacking is insufficient.

[0035] The other type is a fully integrated loading and unloading system. When loading, multiple conveyors are used to deliver the cargo to the vehicle. Sensors on the conveyors detect the cargo's arrival and control its placement within the vehicle. To unload, the system first aligns the onboard conveyor with the ground conveyor, then simultaneously activates multiple conveyors in the system to unload the entire van without stopping. This loading and unloading method saves time, labor, and speeds up unloading, but it also requires too many conveyors, resulting in long conveying distances and a complex system.

[0036] Another type of system has an intelligent loader that is used to load and unload cargo. When the intelligent loader needs to unload cargo, it connects the truck and the loader via a connecting plate. The loader is driven by the rollers on the machine along the track into the carriage. When the loader's front reaches the cargo, it stops and picks up the cargo with a fork. The roller drive reverses and brings the cargo out of the carriage along the track. When the loader reaches the initial position, it puts down the cargo. Finally, the conveyor device places the cargo on the turning platform to complete the unloading. This loader system can enter carriages of different sizes relatively easily, making loading and unloading convenient and saving manpower and material resources. However, the system grabs the cargo with the help of the fork, which requires a relative gap between the cargo. This does not save much space for loading and unloading cargo, and the fork needs to be precisely controlled to transfer the cargo.

[0037] Most of the above-mentioned systems use multiple conveying devices and sensors to load and unload goods. However, the systems still have problems such as large size, too many conveying devices, system redundancy, long loading and unloading time, and difficulty in placing the cargo box when unloading.

[0038] Figure 1 The following schematically shows the structure of the loading and unloading device according to the embodiment of the present utility model. Figure 1 As shown, the present invention proposes a loading and unloading device. The loading and unloading device in the present invention includes a support member 10, a transfer member 20, and a first conveying member 30. The bottom side of the support member 10 is provided with a wheel structure 11, and the support member 10 can be moved by the wheel structure 11. The transfer member 20 is provided on the support member 10. The first conveying member 30 is provided on the support member 10. The transfer member 20 includes a first rotating portion 22 and a suction portion 23. The suction portion 24 is used to suck goods. The first rotating portion 22 is used to transfer goods to the first conveying member 30 and is also used to transfer goods on the first conveying member 30 into a box 200. The first conveying member 30 is used to transfer goods located on the first conveying member 30 along a first direction. The transfer member 20 and the support member 10 are arranged along a second direction, and the first direction and the second direction are arranged to intersect.

[0039] According to the technical solution of the present invention, the support member 10 can support and fix the transfer member 20 and the first conveyor member 30, and can drive the transfer member 20 and the first conveyor member 30 to move closer to or away from the box 200 through the wheel body structure 11. The first rotating portion 22 of the transfer member 20 is used to transfer the goods to the first conveyor member 30 and absorb them through the suction portion 24, thereby realizing the transmission of the goods along the first direction. In addition, the first rotating portion 22 can also transfer the conveyed goods and absorb them through the suction portion 24 and assemble them into the box 200. The loading and unloading device of the present invention can automatically unload the goods in the box 200 and automatically assemble the goods on the first conveyor belt into the box 200, thereby improving the degree of automation and the efficiency of cargo loading and unloading. Specifically, in this embodiment, the first conveyor member 30 can also move in the second direction relative to the support member 10.

[0040] In some embodiments of the present invention, Figure 1 As shown, the transfer member 20 includes a support portion 21 and a first connecting member. The support portion 21 is connected to the support member 10. The first rotating portion 22 is rotatably connected to the support portion 21 via the first connecting member and is capable of rotating about the axis of the first connecting member. The suction portion 24 is connected to the end of the first rotating portion 22 facing away from the support portion 21 and is used to suck up goods. In this embodiment, the support portion 21 is used to raise the first rotating portion 22 to a certain height, thereby facilitating the suction portion 24 on the first rotating portion 22 to suck up goods located higher in the box 200 and move them to the first conveying member 30. The first rotating portion 22 is a robotic arm structure capable of rotating about the axis of the first connecting member, thereby enabling the suction portion 24 to match goods at different heights in the box 200, thereby achieving the suction and movement operation.

[0041] Specifically, in this embodiment, the first connecting member can be a first driving shaft, one end of the first driving shaft is fixedly connected to the first rotating part 22, a driving motor is provided on the support part 21, and the driving end of the driving motor is connected to the first driving shaft, thereby realizing the first rotating part 22 to rotate around the axial direction of the first driving shaft.

[0042] In some embodiments of the present invention, Figure 1 As shown, the transfer member 20 further includes a second rotating portion 23. One end of the second rotating portion 23 is rotatably connected to the first rotating portion 22 via a second connecting member and is capable of rotating about the axis of the second connecting member. The other end of the second rotating portion 23 is connected to the suction portion 24, with the axis of the first connecting member and the axis of the second connecting member intersecting or parallel. In this embodiment, the second rotating portion 23 is a robotic arm structure capable of rotating about the axis of the second connecting member, further enabling the suction portion 24 to match items of different heights within the box 200, thereby achieving suction and movement operations.

[0043] Specifically, in this embodiment, the second connecting member can be a second driving shaft, one end of the second driving shaft is fixedly connected to the second rotating part 23, a driving motor is provided on the first rotating part 22, and the driving end of the driving motor is connected to the second driving shaft, thereby realizing the second rotating part 23 to rotate around the axial direction of the second driving shaft.

[0044] Furthermore, by intersecting the axial directions of the first and second connecting members, the first rotating portion 22 and the second rotating portion 23 can rotate in different directions, respectively. This improves the freedom of movement of the transfer member 20 and allows for more flexible access to items within the box 200. If the axial directions of the first and second connecting members are parallel, the suction portion 24 on the second rotating portion 23 can be positioned further away from the support member 10, allowing for access to items at greater heights, thereby improving versatility and adaptability.

[0045] Specifically, in this embodiment, the transfer member 20 may also be a structure of a robot arm or a combined robot arm.

[0046] In some embodiments of the present invention, the suction portion 24 is a suction cup. In this embodiment, since the cargo in this embodiment is a carton 201 structure and is not very heavy, the suction cup fits against the side of the carton 201, making it easy to fix the carton 201 from the side and move the carton 201, thereby improving reliability.

[0047] Furthermore, in this embodiment, the transfer member 20 further includes a fixed plate, which is disposed on a side of the second rotating portion 23 facing away from the first rotating portion 22, and is hingedly coupled to the second rotating portion 23. Due to the weight of the fixed plate itself, the cross-sectional direction of the fixed plate can always be maintained parallel to the vertical direction (i.e., the second direction), so that the orientation of the fixed plate is not affected during the rotation of the second rotating portion 23 and the first rotating portion 22. The suction portion 24 is connected to the side of the fixed plate facing the carton 201. Since the carton 201 is placed vertically, it is convenient for the suction portion 24 on the vertically placed fixed plate to perform suction, thereby achieving movement.

[0048] In some embodiments of the present invention, Figure 1As shown, the loading and unloading device further includes a second conveyor member 40, which is connected to the support portion 21 and can move relative to the support portion 21 in a second direction. The transfer member 20 is used to pick up and place goods on the second conveyor member 40. The second conveyor member 40 is used to transport goods on the second conveyor member 40 in a third direction. The first direction and the third direction intersect, and the support member 10 and the transfer member 20 are arranged in a direction parallel to the second direction. In this embodiment, the transport direction of the second conveyor member 40 is arranged along the third direction, which enables the carton 201 picked up by the transfer member 20 to be placed on the first conveyor member 30 or the second conveyor member 40, thereby facilitating the transport of the carton 201 in both the first and third directions, thereby improving versatility and adaptability.

[0049] In some embodiments of the present invention, a first visual detection element is further provided on the side of the second rotating portion 23 facing away from the first rotating portion 22. The first visual detection element is used to detect the position of the goods. In this embodiment, the second visual detection element 62 can be a camera. The second visual detection element 62 is disposed on the fixed plate and is positioned toward the cartons 201. It can obtain the position of a large number of cartons 201 and cooperate with the suction unit 24 to suck them one by one.

[0050] In some embodiments of the present invention, Figure 1 As shown, the loading and unloading device also includes a third conveying member 50, which is connected to the second conveying member 40 and can move with the movement of the second conveying member 40. One side of the third conveying member 50 along the third direction corresponds to the position of the second conveying member 40 along the second direction, and one side of the third conveying member 50 along the first direction can correspond to the position of the first conveying member 30 along the second direction. The third conveying member 50 is used to convey the goods located on the third conveying member 50 along the first direction, and the goods located on the second conveying member 40 can be transferred to the first conveying member 30 through the third conveying member 50. In this embodiment, the third conveying member 50 has a first side and a second side. The first side corresponds to the second conveying member 40 and can accept the carton 201 conveyed by the second conveying member 40. At the same time, the third conveying member 50 can move along the second direction, so that the second side of the third conveying member 50 is set corresponding to the first conveying member 30. Since the conveying direction of the third conveying member 50 is the same as that of the first conveying member 30, the carton 201 conveyed by the second conveying member 40 will move toward the first conveying member 30 due to the conveying direction of the third conveying member 50, and finally realize the conveyance of the carton 201 along the first direction.

[0051] Specifically, the above arrangement can extend the conveying distance of the cartons 201, making it easier to convey multiple boxes 200. The combined structure of the first conveying member 30, the second conveying member 40 and the third conveying member 50 can serve the purpose of caching the cartons 201 during conveyance.

[0052] In some embodiments of the present invention, the loading and unloading device further includes a fixing member 61 and a second visual detection member 62. The fixing member 61 is disposed on the support member 10, and the second visual detection member 62 is connected to the visual detection member and is used to detect the relative position between the loading and unloading device and the carrying box 200. In this embodiment, the second visual detection member 62 is a camera that can obtain the position between itself and the box 200 in real time and transmit it to the back-end operator, so that the operator can understand the position of the loading and unloading device and quickly stop the loading and unloading device at the appropriate position and disassemble or assemble the goods through the transfer member 20.

[0053] In some embodiments of the present invention, the wheel structure 11 is a universal wheel, and a plurality of universal wheels are connected to the bottom side of the support member 10 at intervals. In this embodiment, the support member 10 is further provided with a driving component such as a driving motor. The universal wheel includes a rolling wheel, a first driving connection member, a rotating disk, and a second driving connection member. One end of the first driving connection member is inserted into the rolling wheel and fixedly connected to the rolling wheel. The other end of the first driving connection member is drivingly connected to the first driving motor. A rotating disk is provided on the top side of the first driving connection member. A first rack structure is provided on the outside of the rotating disk. The rotating disk is connected to the support member 10 and is connected to the support member 10 through a bearing. The rotating disk can rotate around its own axis. One end of the second driving connection member is connected to the support member 10 and is drivingly connected to the second driving motor. The other end of the second driving connection member is inserted into the support member 10 and a second rack structure is provided on the outer surface. The first rack structure and the second rack structure are meshed and connected.

[0054] Specifically, the second drive connector can rotate the scroll wheel along the axis of the rotating disk through the rotating disk to realize the rotation operation of the universal wheel, and the first drive connector can drive the scroll wheel to rotate to realize the operation of moving the support member 10. The wheel body structure 11 in this embodiment can automatically move along any planar direction under the cooperation of the first drive connector and the second drive connector.

[0055] In some embodiments of the present invention, the end of the first conveyor member 30 away from the transfer member 20 is tilted toward the side away from the support member 10. In this embodiment, this arrangement allows the end of the first conveyor member 30 away from the box body 200 to be higher, which is more suitable for the height of the operator, making it easier for the operator to easily pick up the carton 201 conveyed by the first conveyor member 30 and place it in the next step.

[0056] Furthermore, in this embodiment, the loading and unloading device also includes a controller, which is electrically and communicatively connected to the first visual detector, the second visual detector, the drive motor on the support portion 21, the drive motor on the first rotating portion 22, the suction portion 24, the first drive connector, and the second drive connector, respectively, to facilitate powering these components and acquiring information. In this embodiment, the first conveying member 30, the second conveying member 40, and the third conveying member 50 are all conveyor belt structures or conveyor roller structures.

[0057] Furthermore, if Figure 1 As shown, the operation process of the loading and unloading device of the present invention is as follows: after the van arrives at the designated position, the second visual detector identifies the cargo carton 201 in the van box 200, the controller calculates its distance information, and sends relevant instructions to the wheel body structure 11 to move the wheel body structure 11 toward the direction of the van cargo, and stops moving when it is a certain distance away from the front row of cargo cartons 201 of the van. First, the first visual detector is used to capture the overall distribution of the cargo cartons 201 in the van. After performing relevant calculations, the controller sends instructions to the first rotating part 22 and the second rotating part 23 to rotate the first rotating part 22 and the second rotating part 23, and to enable the suction part 24 to suck the cargo cartons 201. During suction, suction starts from the upper right corner of the truck according to the distribution of cartons 201. When the first rotating part 22 and the second rotating part 23 extend to the vicinity of the carton 201 in the upper right corner of the truck compartment, the first visual detector collects relevant image data nearby. After the controller processes the relevant data, that is, identifies the carton 201 nearby, it sends relevant instructions to the transfer part 20 to make it close to the carton 201. The strong suction cup on the transfer part 20 absorbs the cargo carton 201. After sucking the cargo carton 201, the controller initiates relevant instructions to let the transfer part 20 place the cargo carton 201 on the first conveying part 30. The first conveying part 30 transports it out of the van to the designated conveying equipment, and the equipment transports it to the designated position.

[0058] Specifically, the second conveyor member 40 and the first conveyor member 30 should be in a working state when the unloading device starts unloading. The entire process of the transfer member 20 sucking the cargo carton 201 through the suction cup is more efficient and takes less time than the traditional unloading system unloading with the help of a conveying device. Moreover, the height of the second conveyor member 40 and the first conveyor member 30 from the ground can be raised or lowered, which is conducive to raising the second conveyor member 40 and the first conveyor member 30 when sucking the top cargo carton 201 of the van through the transfer member 20, and lowering the second conveyor member 40 and the first conveyor member 30 when sucking the bottom cargo carton 201 of the van, thereby facilitating the mechanical movement of the transfer member 20.

[0059] Specifically, the transfer member 20 can absorb up to two cargo cartons 201 at a time during the suction operation. If one of the cargo cartons 201 is grabbed and falls, since the loading and unloading device is close to the cargo cartons 201 in the front row of the truck, the second conveying member 40 will catch the carton 201 when it falls, and then transport it to the third conveying member 50. After the third conveying member 50 turns, it is transported to the first conveying member 30, and finally the cargo carton 201 is transported out of the van. At the same time, the first conveying member 30 can also transport the cargo carton 201 absorbed by the transfer member 20.

[0060] The loading and unloading device of the present invention collects data through the first visual detector and the second visual detector, and the controller calculates and processes the relevant data to obtain relevant position information. The system sends instructions to the transfer member 20 to quickly and accurately absorb and accurately coordinate the first conveying member 30, the second conveying member 40 and the third conveying member 50 for indiscriminate transportation. The universal wheels can move forward and backward in any direction, and can also move forward in the direction specified by the controller. This makes the loading and unloading device simple in structure as a whole, with clear division of labor among the devices, a more intelligent system, high unloading efficiency, greatly reduced labor costs, a simple mechanical structure, and relatively simple debugging and maintenance.

[0061] Furthermore, the loading and unloading device of the present invention is specifically used for unloading cargo cartons 201 from vans, which can realize intelligent and efficient unloading of vans and can be applied to the logistics industry or the carton 201 cargo transportation industry. It can also realize intelligent grabbing of the transfer part 20, which is convenient, fast and accurate. The movement of the universal roller is converted from track movement to forward or backward in any direction, and the movement of the universal roller can also be controlled by the controller, so that the entire system is easy to move during operation and no cables are required for signal transmission. There is no need for multiple conveying devices to relay transmission and multiple sensors for cargo transmission control. The device is simpler and occupies a smaller space volume, and it is more convenient for the transfer part 20 to absorb the cargo carton 201.

[0062] Specifically, the loading and unloading device of the present invention is specifically designed for unloading cartons 201 from vans. The system's recognition algorithm can be modified to accommodate various truck unloading scenarios, such as unloading containers at ports, making it suitable for a wide range of applications. Furthermore, the device can move in any direction, with the system controlling its direction and distance, eliminating the need for track-based operation.

[0063] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
