Description

Technical Field

[0001] This utility model belongs to the technical field of loading and unloading auxiliary equipment, and in particular relates to an automated loading and unloading auxiliary equipment for cold chain logistics. Background Technology

[0002] Cold chain logistics is a supply chain management model that uses temperature control technology to maintain a specific low-temperature environment to ensure the stable quality of perishable and highly sensitive goods (such as food, pharmaceuticals, and biological products) throughout the entire process of production, storage, transportation, and distribution. It was established with the advancement of science and technology and the development of refrigeration technology; it is a low-temperature logistics process based on cryogenics and utilizing refrigeration technology. Currently, cold chain transport containers mostly use insulated boxes made of foamed materials such as polyethylene, polypropylene, or polystyrene. These insulated boxes require forklifts to transfer them into the truck bed during loading, unloading, and transportation.

[0003] Existing technologies, such as the Chinese patent (CN218088007U) which discloses an automated loading and unloading auxiliary device for cold chain logistics, include four vertical plates, a drive mechanism, and an adjustment mechanism. The drive mechanism and the adjustment mechanism are mounted on the vertical plates. This invention, through the cooperation of a placement plate, a fixing groove, a servo motor, a threaded rod, a threaded block, a push plate, a guide plate, and rollers, allows forklifts to place items only on the outside of the transport vehicle's cargo box, avoiding the need for workers to move items deep inside the cargo box. When the goods are too heavy, it avoids the need for several workers to work together to move them deep inside the cargo box, thus reducing labor costs and improving work efficiency. Through the cooperation of a connecting groove, rolling bearings, a telescopic rod, a slider, an adjusting rod, a fixing plate, and a rotating block, the height of the loading and unloading operation can be effectively adjusted, while also allowing the placement plate to contact the bottom of the inner wall of the transport vehicle's cargo box, improving the applicability of the auxiliary device.

[0004] This method has the following drawbacks: First, when transferring multi-layered boxed goods, the device cannot rotate or adjust the goods during the forklift transfer process into the box. The orientation of the goods must be specified in advance according to the loading requirements when the forklift is loading. If the orientation of the goods is incorrect, the goods need to be unloaded and readjusted, which increases the loading and unloading time. Second, when stacking goods, the device cannot easily and quickly stack the goods on top of the already loaded goods. The goods still need to be pushed into the box by the device and then manually stacked, which is time-consuming and labor-intensive. Third, when unloading, the device requires workers to manually move the goods to the top of the device before loading. When moving multiple layers of closely packed boxed goods, the operator has few points of leverage on the box and it is difficult to move the box from the side, resulting in great difficulty in unloading.

[0005] Therefore, this utility model provides an automated loading and unloading auxiliary device for cold chain logistics. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model discloses an automated loading and unloading auxiliary device for cold chain logistics.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] like Figures 1 to 5 As shown, the prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: 1. When the device is used to transfer multi-layer boxed goods, it cannot rotate and adjust the goods during the process of the forklift transferring them into the box. The orientation of the goods can only be specified in advance according to the loading requirements when the forklift is loading. When the orientation of the goods is incorrect, the goods need to be unloaded and re-adjusted, which increases the loading and unloading time; 2. When stacking goods, the device cannot easily stack the goods quickly on the already loaded goods. The goods still need to be pushed into the box by the device and then manually stacked, which is time-consuming and labor-intensive; 3. When unloading, the device requires workers to manually move the goods to the top of the device before loading. When moving multi-layer boxed goods that are close together, the operator has few points of leverage on the box and it is difficult to move the box from the side, resulting in great difficulty in unloading. Therefore, the inventor provides an automated loading and unloading auxiliary device for cold chain logistics, including an automatic mobile base 1, a loading platform, a mobile power supply, and a mobile controller. The automatic mobile base 1 is located below the loading platform, the mobile power supply (not shown in the figure) is located in the automatic mobile base 1, and the mobile controller (not shown in the figure) is electrically connected to the automatic mobile base 1 and the loading platform respectively. The loading platform also includes a hydraulic lifting platform 2 and a transport platform 3. The hydraulic lifting platform 2 is located between the automatic mobile base 1 and the transport platform 3, which can rotate and adjust the orientation of the cargo box. A fork slot 4 is provided below the automatic mobile base 1.

[0018] Using the above scheme, when loading the cargo box, the automatic moving base 1 is controlled by the mobile controller to move the loading point. After the operator's hoisting device places the cargo box on the transport platform 3, the forklift inserts the fork head into the fork slot 4 under the automatic moving base 1, and lifts the device and cargo box together and transfers them to the truck bed. After the device is lowered, the forklift is removed. Then, the loading and unloading workers use the mobile controller to move the device to the required loading position inside the truck bed. Then, the hydraulic lifting platform 2 is controlled to move upward to the designated position. Finally, the transport platform 3 is controlled to automatically unload the cargo box to the left, completing the loading operation. When there are not enough forklifts at the loading site and the loading time is tight, forklifts can be placed at the front of the truck bed for lifting the cargo boxes up and down. At the same time, multiple loaders can be deployed to transport the cargo boxes from the unloading point to the front of the truck bed, and the forklifts can lift the goods up and put them into the truck bed. Alternatively, when forklifts cannot be used, a ramp can be set at the front of the truck bed to push the goods into the truck bed through the automatic moving base 1 for loading.

[0019] Furthermore, the hydraulic lifting platform 2 also includes hydraulic push rod a5, hydraulic push rod b6, and fork arm 7. The fork arm 7 is disposed between the automatic moving base 1 and the transport platform 3. The upper and lower ends of the fork arm 7 are hinged to other devices respectively. The lower front end of the fork arm 7 is slidably connected to the upper part of the automatic moving base 1. The hydraulic push rod a5 is disposed below the fork arm 7. The rear end of the hydraulic push rod a5 is connected to the connecting rod between the fork arm 7. The output end of the hydraulic push rod a5 is connected to the connecting rod at the end of the fork arm 7 that is slidably connected to the automatic moving base 1. The hydraulic push rod b6 is disposed above the hydraulic push rod a5. The two ends of the hydraulic push rod b6 are hinged to the connecting rod between the fork arm 7 respectively. When the hydraulic lifting platform 2 is retracted, the forklift 7 is retracted, the hydraulic push rod a5 is extended, and the hydraulic push rod b6 is retracted. When the device needs to lift the cargo box, the hydraulic push rod a5 is retracted and the hydraulic push rod b6 is extended. Under the joint operation, the forklift 7 lifts the transport platform and the cargo box above it, thereby lifting the cargo box to the designated position. During the implementation, the load of the hydraulic push rod a5 and the hydraulic push rod b6 is selected according to the weight of the cargo box being transported.

[0020] Furthermore, the transport platform 3 also includes a lifting mechanism 8 and a placement platform 9, with the lifting mechanism 8 located on the left side of the placement platform 9; The lifting mechanism 8 is used to transport the cargo boxes sent to the left by the placement platform 9 into the truck bed when loading cargo boxes. When unloading, the lifting mechanism 8 can lift the stacked cargo boxes and then transport them to the right onto the placement platform 9. The placement platform 9 is used to load and transport cargo boxes, and the orientation of the cargo boxes can also be adjusted by rotating on the placement platform 9. During implementation, a limit plate can be set on the upper side of the placement platform 9 to fix the bottom of the cargo box and prevent the cargo box from shifting during forklift handling.

[0021] Furthermore, the lifting mechanism 8 also includes a housing a10, a drive motor a11, rollers 12, and a conveyor belt 13. The triangular housing a10 is located on the left side of the placement platform 9. The rollers 12 are rotatably located inside the housing a10. The rollers 12 together form a right-angled triangle structure, and the hypotenuse of the right-angled triangle is parallel to the hypotenuse of the housing a10. The conveyor belt 13 is located outside the rollers 12. The conveyor belt 13 and the rollers 12 are connected by a sprocket and a chain on the side of the connection point (not shown in the figure). The drive motor a11 is located behind the roller 12 located at the right angle. When loading the cargo box from the placement platform 9 into the carriage, the placement platform 9 is controlled by the mobile controller to transport the cargo box to the left. The cargo box is then driven by the drive motor a11 and the rotating conveyor belt 13 driven by the roller 12 to tilt to the left and be sent into the cargo box. During the operation, it is only necessary to hold the cargo box while it is being transported, and the operation of the device can be controlled by the mobile controller. The load of the drive motor a11 is selected according to the weight of the transported goods. When stacked boxes need to be unloaded, the triangular outer shell a10 is adjusted to the position between the boxes using the hydraulic lifting platform 2. Then, the automatic moving base 1 is controlled to move to the left, pushing the front end of the outer shell a10 between the boxes. While the upper box is being lifted upwards, the outer shell a10 is pushed into the bottom of the box. The upper box is then carried to the right onto the placement platform 9 by the right-rotating conveyor belt 13, completing the unloading. In this way, the stacked boxes are first lifted up, and then the boxes are automatically moved to the right for transport. This allows the device to automatically lift and send out stacked boxes even when there is a lack of leverage points, making it easier for operators to unload stacked boxes and reducing the difficulty of unloading in such situations.

[0022] Furthermore, a rubber protrusion (not shown in the figure) is provided above the conveyor belt 13. The rubber protrusions increase the friction between the bottom of the cargo box and the conveyor belt 13, preventing the cargo box from slipping during unloading and loading, and the increased friction helps to lift the cargo box more easily.

[0023] Furthermore, the placement platform 9 also includes a housing b14, rollers a15, a rotating platform 16, and a rotation damper 17. The housing b14 is disposed above the hydraulic lifting platform 2, the rotating platform 16 is rotatably disposed in the middle of the housing a10, the rotation damper 17 is disposed between the rotating platform 16 and the housing b14, and the rollers a15 are rotatably disposed inside the housing b14 on the side of the rotating platform 16. After the cargo box is loaded onto the placement platform 9, the rolling wheel a15 can roll the cargo box out and receive it onto the rotating platform 16. The operator can control the cargo box to rotate on the rotating platform 16, thereby adjusting the cargo box to different orientations, which is convenient for the operator to adjust the orientation of the cargo box and improves the mobility of the device. The rotation damper 17 can increase the rotation resistance of the rotating platform 16, which is convenient for the operator to make precise adjustments. During implementation, the top height of the rotating platform 16 can be set to be higher than the height of the rolling wheel a15 to reduce the friction between the bottom of the cargo box and the rolling wheel a15 during rotation adjustment, which is convenient for adjustment.

[0024] Furthermore, the rotating platform 16 also includes a housing c18, rolling wheels b19, drive wheels 20, and drive motor b21. The housing c18 is disposed above the rotating damper 17. The rolling wheels b19 are rotatably disposed inside the housing c18. The drive wheels 20 are rotatably disposed on the left and right sides inside the housing c18. The drive motor b21 is disposed in front of the drive wheels 20. Driven by the drive motor b21, the drive wheel 20 can actively move the cargo box on the placement platform 9 left and right. During implementation, the load of the drive motor b21 is selected according to the weight of the goods. At the same time, in conjunction with the rotation of the rolling wheel b19, the cargo box can be loaded or transported from the placement platform 9. With the lifting mechanism 8 and the hydraulic lifting platform 2, the cargo box can be automatically loaded and unloaded using the motion controller, which improves the loading efficiency and the automation level of the device. During implementation, anti-slip textures can be set on the surfaces of the rolling wheel b19 and the drive wheel 20.

[0025] In summary, the device is equipped with a hydraulic lifting platform 2, a lifting mechanism 8, and a placement platform 9. The rotating platform 16 in the placement platform 9 allows operators to easily adjust the orientation of the containers, improving the device's mobility. The placement platform 9 can use a motion controller to control the automatic loading and unloading of containers, improving loading efficiency and increasing the device's automation level. The hydraulic lifting platform, in conjunction with the lifting mechanism 8 and the placement platform 9, can first lift the stacked containers and then automatically move them to the right for transport. This allows the device to automatically lift and deliver stacked containers even when there is a lack of leverage, facilitating unloading operations for operators and reducing the difficulty of unloading in such situations.

[0026] The working principle of this utility model: When loading the cargo box, the automatic moving base 1 is controlled by the mobile controller to move the loading to the loading point. After the cargo box is placed on the transport platform 3, the transport platform 3 can hold a single cargo box that passes through the layer. The forklift inserts the fork head into the fork slot 4 under the automatic moving base 1 and lifts the device and the cargo box together and transfers them to the truck bed. After the device is put down, the forklift is moved away. Then the loading and unloading workers hold the mobile controller and move the device to the loading position inside the truck bed. When the device needs to lift the cargo box, hydraulic push rod a5 retracts and hydraulic push rod b6 extends. Working together, the forklift 7 lifts the transport platform and the cargo box above, thereby raising the cargo box to the designated position. Then, the drive motor b21 drives the drive wheel 20, which, together with the rollers a15 and b19, sends the cargo box to the left. After that, the cargo box passes through the drive motor a11 and the roller 12 drives the rotating conveyor belt 13 to tilt to the left and be sent down into the carriage. During the operation, you only need to hold the cargo box while it is being transported, and the device can be controlled by the motion controller. During the process, after the cargo box is loaded onto the placement platform 9, the rolling wheel a15 can roll the cargo box out and receive it onto the rotating platform 16. The operator can control the cargo box to rotate on the rotating platform 16, thereby adjusting the cargo box to different orientations, which is convenient for the operator to adjust the orientation of the cargo box and improves the mobility of the device. The rotation damper 17 can increase the rotation resistance of the rotating platform 16, which is convenient for the operator to make precise adjustments. During implementation, the top height of the rotating platform 16 can be set to be higher than the height of the rolling wheel a15 to reduce the friction between the bottom of the cargo box and the rolling wheel a15 during rotation adjustment, which is convenient for adjustment. When stacked boxes need to be unloaded, the triangular outer shell a10 is adjusted to the position between the boxes by the hydraulic lifting platform 2. Then, the automatic moving base 1 is controlled to move to the left to push the front end of the outer shell a10 into the space between the boxes. While the upper box is being lifted up, the outer shell a10 is pushed into the bottom of the box. The upper box is then carried to the right by the conveyor belt 13, which rotates to the right, and placed onto the placement platform 9 to complete the unloading. In this way, the stacked boxes are first lifted up and then the boxes are automatically moved to the right for transport. This allows the device to automatically lift and send out stacked boxes even when there is a lack of leverage points, making it easier for operators to unload stacked boxes and reducing the difficulty of unloading in this situation. In addition, when there are not enough forklifts at the loading site and the loading time is tight, forklifts can be arranged at the front of the truck bed for lifting the cargo box up and down. At the same time, multiple loaders can be deployed to transport the cargo box from the unloading point to the front of the truck bed, and the forklifts can lift the goods up and put them into the truck bed. Alternatively, when forklifts cannot be used, a ramp can be set at the front of the truck bed to push the goods into the truck bed through the automatic moving base 1 for loading. This concludes the description of the working principle of the device.
