[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0032] Please also refer to Figures 1 to 9 Now, the automatic container loading and unloading device provided by the embodiment of the present utility model is described.
[0033] like Figures 1 to 9 As shown, the automatic loading and unloading device of the container of the present invention includes a container 100, a first cargo board 300 and a second cargo board 400. The container 100 is set on a truck, and a traction device 200 is set in the container 100. The first cargo board 300 is set inside the container 100. A first bottom pulley 330 is set at the bottom of the first cargo board 300. The first cargo board 300 is connected to the traction device 200, and the traction device 200 can pull the first cargo board 300. When moving inside the container 100, a first snap-fitting recess 340 is provided at the end of the first cargo plate 300, and there are several second cargo plates 400. The bottom of the second cargo plate 400 is provided with a second bottom pulley 430, and one end of the second cargo plate 400 is provided with a snap-fitting protrusion 410, and the other end of the second cargo plate 400 is provided with a second snap-fitting recess 420. The snap-fitting protrusion 410 can be snap-fitted with the first snap-fitting recess 340 or the second snap-fitting recess 420.
[0034] During loading, the first cargo pallet 300 is located at the entrance of the container 100. After the first batch of cargo is loaded onto the first cargo pallet 300, the traction device 200 tractions the first cargo pallet 300 to move deep into the interior of the container 100, leaving space for installing the second cargo pallet 400, and the snap-fit protrusion 410 of the second cargo pallet 400 is snap-fitted and installed with the first snap-fit recess 340 of the first cargo pallet 300. Then, the cargo is loaded onto the second cargo pallet 400, and the traction device 200 tractions the first cargo pallet 300 to move deep into the interior of the container 100, continuing to leave space for installing a second cargo pallet 400, and so on, until the traction device 200 pulls the first cargo pallet 300 to the deepest part of the container 100 and fills the container 100.
[0035] When unloading, the outermost cargo is unloaded and the second cargo plate 400 is removed. The traction device 200 moves in the direction to pull the first cargo plate 300 outward, thereby pushing the second cargo plate 400 to move toward the outside of the container 100. The cargo is unloaded and the second cargo plate 400 is removed in turn until all the cargo on the first cargo plate 300 is unloaded and the unloading process is completed.
[0036] The first cargo plate 300 and the second cargo plate 400 are snap-fitted together by the snap-fitting protrusion 410 and the first snap-fitting recess 340, which facilitates disassembly. During the loading and unloading process, it is necessary to install or remove the second loading plate while loading. Therefore, a detachable connection is required between the first cargo plate 300 and the second cargo plate 400. The snap-fit connection makes it more convenient to install or remove the second cargo plate 400 during loading and unloading.
[0037] Exemplarily, the traction device 200 includes a motor 230, a driving wheel, a driven wheel 220 and a traction belt 210. The motor 230 is installed at the bottom of the container 100, and the output end of the motor 230 is connected to the driving wheel. The driving wheel is rotatably arranged at the front end of the container 100, and the driven wheel 220 is rotatably arranged at the rear end of the container 100. The traction belt 210 is respectively wound between the driving wheel and the driven wheel 220. The traction belt 210 is fixedly connected to the first cargo plate 300. The traction belt 210 is driven by the motor 230 to traction and move the first cargo plate 300. The control accuracy is high. When loading, the traction moving distance needs to be controlled to move the first cargo plate 300 a suitable distance to leave a position for the second cargo plate 400. When unloading, the motor needs to reverse and drive the traction belt 210 to pull the first cargo plate 300 toward the outside of the container 100, thereby pushing the second cargo plate 400 to move outward for unloading.
[0038] Illustratively, forklift slots 440 capable of inserting forklift arms are provided at intervals on the first cargo pallet 300 and the second cargo pallet 400. During loading and unloading, the goods are usually lifted or lowered by a forklift for loading and unloading. Therefore, during the loading and unloading process, the forklift arm of the forklift will be inserted into the first cargo pallet 300 and the second cargo pallet 400. Forklift slots 440 capable of inserting forklift arms are provided at intervals on the first cargo pallet 300 and the second cargo pallet 400, which facilitates the forklift to carry the goods. Since the forklift moves the goods onto the second cargo pallet 400 for transportation, a traditional lifting tailgate does not need to be used, saving costs.
[0039] Illustratively, a positioning protrusion 411 is provided in the middle of the engaging protrusion 410, and a positioning groove 421 is provided in the middle of the second engaging recess 420. The positioning protrusion 411 can be inserted into the positioning groove 421, and the positioning groove 421 is closed at both ends along the width direction. The engaging protrusion 410 and the second engaging recess 420 need to be positioned when engaged to avoid misaligned connection and jamming, which causes the traction device 200 to be unable to pull. The positioning groove 421 is an annular groove closed in the left and right directions. The closure of the positioning groove 421 at both ends along the width direction can prevent the engaging protrusion 410 and the second engaging recess 420 from being offset and misaligned in the width direction when engaged.
[0040] Illustratively, the two sides of the said snap-fit protrusion 410 are provided with snap-fit protrusions 412, and the two sides of the second snap-fit recess 420 are provided with snap-fit recesses 422. The snap-fit protrusions 412 and the snap-fit recesses 422 are complementary in shape. The snap-fit protrusions 412 and the snap-fit recesses 422 are complementary in shape and can be hooked and snapped to each other. When the traction device 200 pulls the first cargo plate 300, it can drive the other second cargo plates 400 to move.
[0041] Exemplarily, the side of the first cargo plate 300 is provided with a side pulley 320, and the side of the first cargo plate 300 is easy to contact the side of the container 100 when moving. The provision of the side pulley 320 allows the first cargo plate 300 to perform rolling friction when contacting the side of the container 100, making the movement smoother.
[0042] For example, the first cargo pallet 300 is vertically provided with a cargo baffle 310 on one side close to the rear end of the container 100 for preventing the cargo from collapsing. The cargo is first loaded onto the first cargo pallet 300. If the cargo is not supported by the cargo baffle 310 on the side facing the inside of the container 100, it is easy to collapse. When the cargo is loaded onto the second cargo pallet 400, since the first cargo pallet 300 has been loaded with cargo, it can provide support for the cargo on the second cargo pallet 400, so the second cargo pallet 400 does not need to be provided with a cargo baffle 310.
[0043] Illustratively, a side baffle 311 is provided on the side of the cargo baffle 310, and a top baffle 312 is provided on the top of the cargo baffle 310. The side baffle 311 and the top baffle 312 form a limiting structure, which limits the cargo on the first cargo plate 300 and prevents it from collapsing, providing support for the cargo. The top baffle 312 can also prevent the cargo from flipping up to the outside of the cargo baffle 310.
[0044] Exemplarily, the automatic loading and unloading device for the container also includes a platform plate 500, and the upper surface of the platform plate 500 is provided with upper fork grooves 510 for inserting forklift arms, and the lower surface of the platform plate 500 is provided with lower fork grooves 520 for inserting forklift arms. The platform plate 500 is used to place goods on the ground. When the forklift moves the goods on the platform plate 500 onto the truck, the forklift arm of the forklift can be inserted into the upper fork groove 510 and then lift the goods, so that the platform plate 500 will not be lifted up together. Moreover, not lifting the platform plate 500 and loading it onto the truck can avoid the platform plate 500 occupying the height space of the container 100, so that the container 100 can load more goods or higher goods; the forklift arm of the forklift can also be inserted into the lower fork groove 520 and then lifted, so that the platform plate 500 and the goods can be lifted together.
[0045] The automatic container loading and unloading device provided by the present invention has the following beneficial effects compared with the prior art:
[0046] The traction device 200 of the present invention is connected to the first cargo plate 300, and the traction device 200 can pull the first cargo plate 300 to move inside the container 100. The first engaging recess 340 of the first cargo plate 300 can engage with the engaging protrusion 410 of the second cargo plate 400. Therefore, when the traction device 200 pulls the first cargo plate 300, the second cargo plate 400 can be pulled by the first cargo plate 300 to move at the same time. There are multiple second cargo plates 400, and multiple second cargo plates 400 can be connected by engaging. The snap-fitting protrusion 410 of the cargo plate 400 can be snap-fitted with the second snap-fitting recess 420 of the adjacent second cargo plate 400, so that several second cargo plates 400 can be connected together. When the traction device 200 pulls the first cargo plate 300 to move, it can pull multiple second cargo plates 400 to move through the first cargo plate 300. The first bottom pulley 330 and the second bottom pulley 430 are respectively provided at the bottom of the first cargo plate 300 and the second cargo plate 400, so that the movement of the first cargo plate 300 and the second cargo plate 400 is smoother and more labor-saving. During loading, the first pallet 300 is located at the entrance of the container 100. After the first batch of goods is loaded onto the first pallet 300, the traction device 200 pulls the first pallet 300 to move deep into the interior of the container 100, leaving space for installing the second pallet 400. The engaging protrusion 410 of the second pallet 400 is engaged with the first engaging recess 340 of the first pallet 300, and then the goods are loaded onto the second pallet 400. The traction device 200 pulls the first pallet 300 to move deep into the interior of the container 100, leaving space for installing the second pallet 400. A second pallet 400 can be installed, and so on, until the traction device 200 pulls the first pallet 300 to the deepest part of the container 100, filling the container 100. During unloading, the outermost cargo is unloaded and the second pallet 400 is removed. The traction device 200 moves in the direction of the first pallet 300 to pull outward, thereby pushing the second pallet 400 toward the outside of the container 100. The cargo is unloaded and the second pallet 400 is removed in sequence until all the cargo on the first pallet 300 is unloaded, completing the unloading process. By using the traction device 200 to pull the first pallet 300 to move the cargo to the deepest part of the container 100, manual handling is avoided, reducing labor costs and improving loading efficiency and speed. Moreover, since manual handling is not required, no space is required for workers to move the cargo during loading, allowing the container 100 to be filled more fully, thereby improving the cargo loading rate of the container 100.
[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
