Description

Technical Field

[0001] This invention relates to the field of loading equipment, specifically a cargo stacking and unloading structure. Background Technology

[0002] Compared to other ordinary trucks, container trucks and container trucks have advantages such as large transport capacity, full utilization of space, safety, aesthetics, and rain and moisture protection. They are widely used in various industries, and the fully sealed transportation is not affected by the weather.

[0003] Since both container trucks and cargo trucks require sealed containers, conventional containers typically only have a rear door for loading and unloading goods. Only a few, or customized, vehicles may have smaller side doors. When transporting goods using container trucks, it's essential to fill the container as much as possible with cargo. Otherwise, large gaps between goods or between goods and the truck walls can easily lead to tipping, sliding, and shifting of cargo during transport. This can damage the goods and cause the vehicle's center of gravity to shift, posing a significant safety hazard.

[0004] Currently, the common practice in the market is to fill containers or cargo containers with goods by manually handling and stacking them. Alternatively, forklifts and wooden pallets are used to move goods into the truck bed, and then workers manually stack the goods on the pallets little by little until the truck bed is full. However, it is impossible to fill containers or cargo containers with goods using only forklifts. All existing methods rely heavily on manual labor, which can lead to various degrees of workplace injuries for workers due to prolonged heavy lifting. Furthermore, when dealing with large volumes of goods, the current manual stacking method consumes a significant amount of time in loading and unloading, resulting in low loading efficiency.

[0005] The space inside a container is limited, and as the amount of cargo increases, the space becomes smaller and smaller. It is difficult for mechanical equipment to stack and fill the space inside a container within its limited space.

[0006] Therefore, how to use mechanical equipment to stack goods first, and then fill the space inside the container or shipping container through the door at the rear of the container or shipping container with the goods while reducing or even eliminating manual labor, is a major problem that the transportation industry needs to solve. Summary of the Invention

[0007] The purpose of this invention is to propose a cargo stacking and loading structure, which aims to solve the technical problems of existing manual cargo stacking and loading methods that lead to varying degrees of work-related injuries and low loading efficiency.

[0008] To achieve the above objectives, the present invention proposes a cargo stacking and unloading structure, comprising: a first frame, which, in use, abuts against the cargo compartment of a truck; a second frame, which is fixedly connected to the first frame and located above the first frame; the second frame is provided with a first tilting mechanism, a conveying mechanism, and a second tilting mechanism sequentially arranged from back to front; both the first and second tilting mechanisms are hinged to the second frame; the conveying mechanism is movably mounted on the second frame, allowing cargo to be tilted upwards via the first tilting mechanism and moved onto the conveying mechanism; the conveying mechanism then moves the cargo forward and stacks it laterally on the second tilting mechanism. The second flipping mechanism flips downwards to obtain vertically stacked goods; a moving component, movably mounted on the first frame, is located below the second flipping mechanism and can reciprocate into the cargo compartment of the truck; a loading and unloading mechanism is mounted on the moving component, comprising a supporting component and a pushing component. After the second flipping mechanism flips downwards, the second flipping mechanism and the supporting component overlap in the left-right direction to jointly support the vertically stacked goods. The supporting component is located in front of the pushing component and can move backwards relative to the pushing component to unload the goods on the supporting component.

[0009] By coordinating the first tilting mechanism, the conveying mechanism, and the second tilting mechanism, cargo stacking is achieved, preventing worker injuries and improving stacking efficiency. After the second tilting mechanism tilts downwards, the supporting component, carrying the cargo, extends into the carriage along with the moving component to the appropriate position. Then, the supporting component moves backward relative to the pushing component, effectively pressing the cargo against the supporting component until the supporting component is completely removed from under the cargo, thus completing the unloading within the carriage. The size of the supporting component is adaptively adjusted according to the width of the carriage, ensuring that each loading and unloading operation fills the carriage's width. Several cycles are sufficient to fill the carriage. This batch loading and unloading method, which fills the carriage, is suitable not only for loading and unloading empty carriages but also for partially or completely empty carriages, offering flexibility.

[0010] Preferably, after the second flipping mechanism flips downward, the second flipping mechanism and the supporting component overlap in the vertical direction so that they jointly support the vertically stacked goods; the second flipping mechanism includes a second flipping bracket for supporting goods, and the second flipping bracket has a plurality of passage gaps for the supporting component and the pushing component to pass through.

[0011] By staggering the second tilting mechanism and the supporting component, the volume of the supporting component is greatly reduced while supporting the goods, allowing the width of the supporting component to be less than or equal to the width of the vertically stacked goods. This enables the supporting component to fill the space inside the car body in the width direction when it enters the car.

[0012] Preferably, the pushing component includes a pushing drive and at least one pushing member, the pushing drive component being tractively connected to the pushing member; the supporting component includes a supporting drive component and at least two second forks for picking up goods, the supporting drive component being tractively connected to the second forks. When unloading in the cargo compartment of the truck, the supporting drive component drives the second forks to move backward, and the pushing drive component simultaneously drives the pushing member to move forward, thereby unloading the goods on the second forks; the loading and unloading mechanism includes a support frame and a hinge drive, the support frame being mounted on the moving component, the hinge drive, the pushing component, and the supporting component all being mounted on the support frame, the rear side of the second forks being hinged to the support frame in the vertical direction, and the output end of the hinge drive being tractively connected to the rear end of the second forks. During unloading, the supporting drive component drives the second forks to move backward, and the pushing drive simultaneously drives the pushing member to move forward, both moving simultaneously, thereby quickly unloading the goods picked up from the second forks into the cargo compartment. After the second fork is hinged to the support frame, the second fork can swing in the up and down direction, making the second fork more flexible and applicable to a wider range of situations.

[0013] Preferably, the second tilting bracket is provided with a plurality of first forks for supporting goods, and the plurality of first forks are provided with the aforementioned passage gaps; the supporting assembly further includes a support plate, the support plate being detachably installed from both the first and second forks, and the support plate being located above at least one of the first and second forks, such that: before the second tilting mechanism tilts downward, the support plate is installed on the first forks to support goods; after the second tilting mechanism tilts downward, the support plate is installed on both the first and second forks to support goods; when the moving assembly drives the second forks to move forward, the support plate is installed on the second forks to transport the goods into the cargo compartment of the truck.

[0014] Using a pallet to support goods is especially suitable for loading and unloading bulk goods. The first and second forks share a single pallet, and the goods remain on the pallet throughout the two processes of flipping and unloading into the cargo compartment.

[0015] Preferably, the left and right sides of the second fork are provided with first fixing members that are narrower at the top and wider at the bottom. The bottom surface of the support plate is provided with fixing units that correspond one-to-one with the second fork. The fixing unit includes two opposing second fixing members. Both of the second fixing members are narrower at the bottom and wider at the top. The interval W1 between the two second fixing members in one fixing unit is greater than or equal to the distance W2 between the left and right sides of the second fork, so that when the support plate is installed on the second fork, the first fixing members and the second fixing members engage.

[0016] The first and second fixing parts facilitate the quick installation of the support plate onto the second fork in the vertical direction.

[0017] Preferably, the first fixing member has a guide surface, a first vertical surface, a first inclined surface and a second vertical surface arranged from top to bottom on the side near the second fixing member, and the second fixing member has a third vertical surface, a second inclined surface and a fourth vertical surface arranged from top to bottom on the side near the first fixing member, such that after the first fixing member and the second fixing member are engaged, the first vertical surface abuts against the third vertical surface, the first inclined surface abuts against the second inclined surface, and the second vertical surface abuts against the fourth vertical surface.

[0018] By setting the first vertical surface, the first inclined surface, and the second vertical surface to abut against the third vertical surface, the second inclined surface, and the fourth vertical surface respectively, the connection between the support plate and the second fork can be made stable and not easily loosened or detached when moving back and forth. At the same time, the guide surface can facilitate the engagement of the first fixing member and the second fixing member in the vertical direction.

[0019] Preferably, the lower surface of the support plate extends downward to form an abutment portion, such that when the support plate is installed on the first fork, the abutment portion abuts against the front end of the first fork. This abutment portion abuts against the front end of the first fork, improving the stability of the two components during installation.

[0020] Preferably, the lower surface of the support plate is provided with insertion units corresponding to the first forks. Each insertion unit includes at least two oppositely arranged insertion members, both of which are narrower at the back and wider at the front. A insertion gap is left between the two insertion members, the width of which is greater than or equal to the width W4 between the left and right sides of the first fork, such that when the support plate is installed on the first fork, the first fork is inserted into the insertion gap. Simultaneously with the installation of the support plate and the first fork, the insertion members prevent the first fork and the support plate from shifting in the left-right direction.

[0021] Preferably, the bottom surface of the front end of the aforementioned support plate is provided with an inclined member to facilitate the removal of the support plate from under the cargo inside the truck bed. The inclined member slopes downward from front to back. The inclined member facilitates the removal of the support plate from under the cargo when it is lowered with the second fork, avoiding scratching and wear against the bottom of the truck bed.

[0022] Preferably, the aforementioned moving assembly includes a first rotary drive, a first gear, a first rack, a first guide rail, a moving bracket, and a plurality of first sliders. At least two of each of the first gear, first rack, and first guide rail are provided. The first guide rail is mounted on the first frame along the front-rear direction. Each of the first sliders is slidably mounted on the first guide rail. The moving bracket is mounted on the first sliders. The first rack is mounted on the outer sidewalls of both the left and right sides of the moving bracket. The first rotary drive is mounted on the first frame. The first gear is connected to the output end of the first rotary drive and meshes with the first rack. The movement of the moving bracket can be stably controlled via the first guide rail, first sliders, first gear, and first rack.

[0023] Preferably, the aforementioned support drive assembly includes a second rotary drive, a second gear, a second rack, a second guide rail, and a plurality of second sliders. At least two of each of the second gear, second rack, and second guide rail are provided. The second guide rail is disposed on the movable bracket along the front-rear direction. Each of the second sliders is slidably disposed on the second guide rail. The support frame is disposed on the second sliders. The second rack is disposed on the inner sidewalls of both the left and right sides of the movable bracket. The second rotary drive is disposed on the support frame. The second gear is drively connected to the output end of the second rotary drive, and the second gear meshes with the second rack. The movement of the support frame can be stably controlled through the second guide rail, second sliders, second gear, and second rack.

[0024] Preferably, the first flipping mechanism includes a first flipping bracket and a first flipping drive. The first part and the second part of the first flipping bracket are arranged at an angle with their openings facing backward. The second part is hinged to the second frame. The first frame is provided with the first flipping drive, and the output end of the first flipping drive is connected to the second part. The second part is provided with a first rolling assembly, which includes a fourth rotary drive, a first transmission belt, and several rolling units. Each rolling unit includes a roller, a transmission rod, and two first transmission wheels. The roller is sleeved on the transmission rod, which is rotatably mounted on the second part. The two first transmission wheels are respectively sleeved on both ends of the transmission rod. At least two first transmission belts are provided, which are wound around the several first transmission wheels and the output end of the fourth rotary drive. When goods are placed in the first part, the rollers abut against the goods. The third and fourth parts of the second flipping bracket are arranged at an angle with their openings facing forward. The fourth part is provided with a second rolling assembly, which has the same structure as the first rolling assembly. The height H1 of the fourth part is greater than the height H2 of the second part.

[0025] By coordinating the first tilting mechanism, the conveying mechanism, and the second tilting mechanism, goods can be stacked, preventing worker injuries and improving loading and unloading efficiency. The inclusion of a first rolling assembly and a second rolling assembly further enhances cargo conveying efficiency.

[0026] Preferably, the system further includes a movable tilting and protective mechanism. This mechanism, used to abut the goods from the left and right sides during tilting, is located on the second frame near the first and / or second tilting mechanisms. The tilting and protective mechanism includes a first clamping assembly and a second clamping assembly. The first clamping assembly includes a first clamping arm, a protective plate, and a first clamping drive. The first clamping arm includes a first segment and a second segment, which are arranged at an angle with their openings facing the goods. The protective plate is connected to the first segment, and the second segment is hinged to the second frame. The lower side of the second segment is drively connected to the first clamping drive, allowing the protective plate to move closer to or away from the goods under the influence of the first clamping drive. The second clamping assembly has the same structure as the first clamping assembly and is symmetrically arranged on the left and right sides of the goods. This tilting and protective mechanism prevents the goods from falling during the tilting process.

[0027] Preferably, the conveying mechanism includes a third rotary drive, second transmission wheels, transmission bars, a main drive shaft, a secondary drive shaft, and several chain plates. At least one main drive shaft and one secondary drive shaft are provided, both rotatably connected to the second frame.

At least two transmission bars are provided, wound around the second transmission wheels of the main drive shaft and the secondary drive shaft. Both ends of each chain plate are fixedly connected to one of the two transmission bars. Conveying goods via chain plates increases the load-bearing capacity.

[0028] Preferably, the system further includes a wood-removing mechanism for removing the wood support. This mechanism includes a third frame, a third guide rail, a third slider, a movable seat, a movable plate, a first lifting drive, a second clamping drive, a movable arm, a fixed arm, and a horizontal drive assembly.

The fifth rotary drive is mounted on the third frame. The horizontal drive main shaft and the horizontal drive secondary shaft are rotatably mounted on the third frame. At least one of each of the third drive wheel, the fourth drive wheel, and the second drive belt is provided. The third drive wheel is sleeved on the horizontal drive main shaft, the fourth drive wheel is sleeved on the horizontal drive secondary shaft, and the second drive belt is wound around the third and fourth drive wheels. The movable seat is fixedly connected to the second drive belt via a connector. The fifth rotary drive is connected to the horizontal drive main shaft. Removing the wooden pallet supporting the goods through the wooden pallet removal mechanism facilitates both the stacking of goods and the recovery of the wooden pallet.

[0029] The present invention has the following beneficial effects:

[0030] 1. By coordinating the first flipping mechanism, the conveying mechanism, and the second flipping mechanism, goods can be stacked, replacing manual operation, avoiding workplace injuries, and improving the efficiency of goods stacking.

[0031] 2. After the supporting component, carrying the goods, extends into the carriage to the corresponding position along with the moving component, the supporting component moves backward relative to the pushing component. This means that the pushing component presses against the goods on the supporting component until the supporting component is completely removed from under the goods, thus completing the unloading in the carriage. This solution only moves in the front-to-back direction. Compared with using a robotic arm to grip the goods from left to right to complete the loading and unloading, this solution can place more goods in the left-to-right direction. On the one hand, it can make full use of the space in the carriage, and on the other hand, it can reduce the gap between goods and the gap between goods and the carriage, thereby limiting the movement space of the goods and effectively preventing the goods from tipping over, sliding, or shifting during transportation, which could cause damage to the goods.

[0032] 3. The size of the supporting components is adaptively adjusted according to the width of the carriage, so that the space in the width direction of the carriage can be filled every time it is loaded and unloaded. After several cycles, the space inside the carriage can be filled, effectively replacing manual stacking inside the carriage, avoiding accidents such as workplace injuries, and also effectively improving the loading and unloading efficiency of goods.

[0033] 4. In various industries, there is a common need to deliver or load goods at multiple locations. This solution, through batch loading and unloading, is not only suitable for loading and unloading empty carriages, but also for loading and unloading partially or completely empty carriages, making it more flexible and applicable to a wider range of situations.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0076] like Figures 1 to 36As shown, a cargo stacking and unloading structure includes: a first frame 1, which, in use, abuts against the cargo compartment of a truck; a second frame 2, which is fixedly connected to the first frame 1 and located above the first frame 1. The second frame 2 is provided with a first tilting mechanism 3, a conveying mechanism 4, and a second tilting mechanism 5 sequentially arranged from back to front. Both the first tilting mechanism 3 and the second tilting mechanism 5 are hinged to the second frame 2. The conveying mechanism 4 is movably mounted on the second frame 2, allowing cargo to be tilted upwards via the first tilting mechanism 3 and moved onto the conveying mechanism 4. The conveying mechanism 4 then moves the cargo forward and stacks it laterally on the second tilting mechanism 5, while the cargo is tilted downwards via the second tilting mechanism 5. The goods are flipped to obtain a vertically stacked stack; a movable component 6 is movably mounted on the first frame 1 and is located below the second flipping mechanism 5. The movable component 6 can reciprocate to the cargo compartment of the truck; a loading and unloading mechanism 7 is mounted on the movable component 6 and includes a supporting component 71 and a pushing component 72. After the second flipping mechanism 5 flips downward, the second flipping mechanism 5 and the supporting component 71 overlap in the left and right directions so that they jointly support the vertically stacked goods. The supporting component 71 is located in front of the pushing component 72 and can move backward relative to the pushing component 72 to unload the goods on the supporting component 71.

[0077] like Figure 25-27 As shown, during operation, a forklift picks up the goods to be loaded / unloaded (10) and places them onto the first tilting mechanism 3, or the first tilting mechanism 3 is connected to an intelligent warehousing system, which then transports the goods onto the first tilting mechanism 3. After the goods are loaded onto the first tilting mechanism 3, it tilts the goods upwards, thus transporting them to the conveyor mechanism 4. The conveyor mechanism 4 then moves the goods forward. At this time, the second tilting mechanism 5 is in an upward tilting state, and the goods on the conveyor mechanism 4 move to contact the second tilting mechanism 5. The forklift or intelligent warehousing system continues to transport goods onto the first tilting mechanism 3, repeating the above process until the horizontally stacked goods on the second tilting mechanism 5 reach a set quantity. After the horizontally stacked goods on the second tilting mechanism 5 reach the set quantity, the second tilting mechanism 5 tilts the horizontally stacked goods downwards, thus obtaining the desired result. Figure 26 The goods are stacked vertically as shown. At this time, the goods are simultaneously supported by the second tilting mechanism 5 and the supporting assembly 71. Figure 27As shown, after the vertically stacked goods are supported by the support component 71, the moving component 6 moves forward into the carriage, thereby driving the pushing component 72, the support component 71, and the vertically stacked goods on the support component 71 into the carriage. After the support component 71, carrying the goods, extends into the carriage with the moving component 6 to the corresponding loading and unloading position, the support component 71 moves backward relative to the pushing component 72, which is equivalent to the pushing component 72 pressing against the goods on the support component 71 until the support component 71 is completely removed from under the goods, thereby completing the unloading in the carriage.

[0078] By coordinating the first flipping mechanism 3, the conveying mechanism 4, and the second flipping mechanism 5, goods can be stacked, replacing manual operation, avoiding workplace injuries, and improving the efficiency of goods stacking and loading / unloading.

[0079] During the unloading process inside the carriage, this solution only moves in the front-to-back direction. Compared with using a robotic arm to grip and unload goods from left to right, this solution can place more goods in the left-to-right direction, so that the width of the goods stacked on the supporting component 71 is close to the width of the carriage. This allows the carriage to be filled with space in the width direction with each loading and unloading. On the one hand, it can make full use of the space in the carriage, and on the other hand, it can reduce the gap between goods and the gap between goods and the carriage, thereby limiting the movement space of the goods and effectively preventing the goods from being damaged by tipping, sliding and shifting during transportation.

[0080] The width of the support component 71 is adaptively adjusted according to the width of the carriage, ensuring that the carriage is filled in both the width and height directions with each loading and unloading operation. After several cycles, the carriage is filled in the length direction, effectively replacing manual loading and stacking within the carriage, avoiding workplace injuries and significantly improving loading and unloading efficiency. The support component 71 can be a plate-like structure or a fork-like structure used with wooden pallets. The width direction corresponds to the left-right direction, the height direction to the up-down direction, and the length direction to the front-back direction. It is important to note that even with manual loading, unloading, and stacking of goods within the carriage, the space cannot be completely filled. A small gap is permissible in the industry, typically filled with materials such as wooden strips, cardboard, or plastic. This solution can also be used if filler is required. The purpose of this solution is to replace manual labor in the process of loading and unloading goods into the carriage.

[0081] In various industries, there is a common need to deliver or load goods at multiple locations. This solution, through batch loading and unloading, is not only suitable for loading and unloading empty carriages, but also for loading and unloading partially or completely empty carriages, making it more flexible and applicable to a wider range of situations.

[0082] The moving component 6 extends into the carriage until it reaches the unloading position. The unloading is then carried out via the supporting component 71 and pushing component 72 on the moving component 6. This process avoids friction between the goods and the carriage floor, preventing wear and tear on both. The moving component 6 can be a rack and pinion structure or a guide rail and slider structure, etc.

[0083] The rearward movement of the supporting component 71 relative to the aforementioned pushing component 72 includes two scenarios: one is that only the supporting component 71 moves while the pushing component 72 remains stationary; the other is that both the supporting component 71 and the pushing component 72 move, with a difference in movement between them, or they move in opposite directions. The freight truck can be a container truck, container car, or other freight vehicle. Figure 26 As shown, the second flipping mechanism 5 and the supporting component 71 can overlap in the left and right directions to jointly support vertically stacked goods, and can be set to overlap or not overlap in other directions.

[0084] The first frame 1 can be movable, for example, by installing rollers on the support legs of the first frame 1 so that the first frame 1 can move to abut against the truck bed. Alternatively, the first frame 1 can be fixed, and can be lifted and moved by mechanical equipment to abut against the truck bed. Preferably, the first frame 1 is movable. The fixed connection between the first frame 1 and the second frame 2 can be a threaded connection, welding, or integral molding. Both the first tilting mechanism 3 and the second tilting mechanism 5 are hinged to the second frame 2. The hinge can be achieved by a hinge member fixedly connected to the second frame 2, or by directly opening hinge holes in the second frame 2 and using hinge rods to engage the hinge. The conveying mechanism 4 can be a plate chain conveyor, belt conveyor, or roller conveyor, etc.

[0085] Furthermore, after the second flipping mechanism 5 flips downward, the second flipping mechanism 5 and the supporting component 71 overlap in the vertical direction so that they jointly support the vertically stacked goods; the second flipping mechanism 5 includes a second flipping bracket 51 for supporting goods, and the second flipping bracket 51 has a plurality of passage gaps 52 for the supporting component 71 and the pushing component 72 to pass through.

[0086] By setting a passage gap 52 on the second tilting bracket 51, the second tilting mechanism 5 and the supporting component 71 are arranged in an overlapping and staggered manner in the left-right and up-down directions. On the one hand, this allows the second tilting mechanism 5 and the supporting component 71 to support the goods while greatly reducing the volume of the supporting component 71, the second tilting mechanism 5, and the whole, resulting in high space utilization and saving production costs. On the other hand, the width of the supporting component 71 can be less than or equal to the width of the vertically stacked goods. Thus, when the supporting component 71 enters the carriage, the space inside the carriage can be filled in the width direction. This avoids the situation where the space inside the carriage is not fully filled, which could lead to the goods being easily tipped over, slipped, or shifted during road transportation, causing damage to the goods and causing the center of gravity of the transport vehicle to shift, posing a significant safety hazard to the vehicle. If the space inside the carriage cannot be filled, manual rework is required.

[0087] Furthermore, the second flipping mechanism 5 and the supporting component 71 are arranged in an overlapping and staggered manner in the left-right and up-down directions. Goods can be placed onto the supporting component 71 with just one flip, resulting in high efficiency and speed. This also reduces the number of horizontal movements required for vertically stacked goods, preventing goods from shifting during multiple movements, which could lead to insufficient loading of the truck bed or interference with other goods during loading and unloading, necessitating manual adjustments and ensuring the stability of the loading and unloading process. The shape, size, and quantity of the supporting component 71, pushing component 72, and passage gap 52 can be adaptively adjusted according to actual usage requirements.

[0088] Further, the aforementioned pushing assembly 72 includes a pushing drive 721 and at least one pushing member 722, the pushing drive 721 being convexly connected to the pushing member 722; the aforementioned supporting assembly 71 includes a supporting drive assembly 711 and at least two second forks 712 for picking up goods, the supporting drive assembly 711 being convexly connected to the second forks 712, and when unloading goods in the cargo compartment of the aforementioned truck, the supporting drive assembly 711 drives the second forks 712 to move backward, the pushing drive 721... The component 1 synchronously drives the pusher 722 to move forward to unload the goods on the second fork 712; the loading and unloading mechanism 7 includes a support frame 73 and a hinge drive 74. The support frame 73 is mounted on the moving component 6. The hinge drive 74, the pusher 72 and the supporting component 71 are all mounted on the support frame 73. The rear side of the second fork 712 is hinged to the support frame 73 in the vertical direction. The output end of the hinge drive 74 is connected to the rear end of the second fork 712.

[0089] During unloading, the support drive assembly 711 drives the second fork 712 to move backward, while the push drive 721 simultaneously drives the pusher 722 to move forward. The second fork 712 and the pusher 722 move simultaneously and in opposite directions, thus quickly unloading the goods picked up by the second fork 712 into the truck bed. Compared to only one moving, using a lower-power drive to move both achieves the same speed as a higher-power drive for one. Furthermore, rapid unloading prevents the lower layer of goods from shifting due to friction, ensuring unloading stability. Shifting would have the aforementioned adverse consequences. The lower layer of goods refers to those located at the bottom of a vertically stacked cargo. Additionally, the simultaneous movement of the second fork 712 and the pusher 722 ensures that the goods remain in their designated loading / unloading position throughout the entire process, from the second fork 712 carrying the goods into the truck bed with the moving assembly 6 until the second fork 712 completely withdraws from under the goods. The goods remain in their designated loading / unloading position, ensuring the truck bed is fully filled.

[0090] The second fork 712 is particularly suitable for loading and unloading goods pre-stacked on wooden pallets. The push drive 721 is housed inside the support frame 73, which encloses the push drive 721. Both the hinged drive 74 and the push drive 721 are cylinders, hydraulic cylinders, or electric cylinders, and can be adjusted according to the weight of the goods. For example, a hydraulic cylinder can be used for heavier goods, while a pneumatic cylinder can be used for lighter goods. The number of pushers 722 and the second fork 712 can be adjusted adaptively according to actual usage requirements. For example, when the weight of the goods to be loaded and unloaded is relatively large, the number of pushers 722 and the second fork 712 can be appropriately increased.

[0091] After the second fork 712 is hinged to the support frame 73, the second fork 712 can swing in the vertical direction, making it more flexible and applicable to a wider range of situations. Furthermore, during unloading, the second fork 712 can tilt slightly downwards first and then move backwards, further increasing the unloading speed while preventing the goods from shifting when the second fork 712 is pulled away from the bottom surface of the goods. The hinge method between the second fork 712 and the support frame 73 is similar to that of the second tilting mechanism 5 and the second frame 2. Preferably, the hinge is achieved by directly opening hinge holes in the support frame 73, which allows for a smaller overall width of the loading and unloading mechanism 7.

[0092] Furthermore, the second tilting support 51 is provided with a plurality of first forks 53 for supporting goods, and the plurality of first forks 53 are provided with passage gaps 52; the supporting assembly 71 also includes a supporting plate 713, which is detachably installed on both the first forks 53 and the second forks 712. The supporting plate 713 is located above at least one of the first forks 53 and the second forks 712, such that: before the second tilting mechanism 5 tilts downward, the supporting plate 713 is installed on the first forks 53 to support goods; after the second tilting mechanism 5 tilts downward, the supporting plate 713 is installed on both the first forks 53 and the second forks 712 to support goods; when the moving assembly 6 moves the second forks 712 forward, the supporting plate 713 is installed on the second forks 712 to transport goods into the cargo compartment of the truck. At least two first forks 53 are provided.

[0093] like Figures 28-30 As shown in the figure, when the support plate 713 is not set, the flipping process of the first fork 53 and the second fork 712 in the second flipping mechanism 5, the overlapping process of the second flipping mechanism 5 and the support assembly 71, and the process of the support assembly 71 conveying goods into the carriage are respectively shown in the figure. Before the second flipping mechanism 5 flips and when the second flipping mechanism 5 flips downward, the goods abut against the first fork 53. After the second flipping mechanism 5 flips downward, the goods abut against both the first fork 53 and the second fork 712. When the support assembly 71 conveys goods into the carriage, the goods abut against the second fork 712 only. After the second fork 712 unloads the goods, the moving assembly 6 drives the second fork 712 to move backward and reset until the second fork 712 and the first fork 53 are overlapped and staggered in the left-right direction and the up-down direction. The above process is repeated during the next round of loading and unloading of goods.

[0094] like Figures 31-33As shown in the figure, when the support plate 713 is set, the flipping process of the first fork 53 and the second fork 712 of the second flipping mechanism 5, the overlapping process of the second flipping mechanism 5 and the support assembly 71, and the process of the support assembly 71 conveying goods into the carriage are respectively shown in the figure. Before the second flipping mechanism 5 flips and when the second flipping mechanism 5 flips downward, the goods are supported by the support plate 713 installed on the first fork 53. After the second flipping mechanism 5 flips downward, the goods are simultaneously supported by the support plate 713 installed on the first fork 53 and the second fork 712. When the support assembly 71 conveys goods into the carriage, the goods are only supported by the support plate 713 installed on the second fork 712. After the support plate 713 unloads the goods, the moving assembly 6 drives the second fork 712 and the support plate 713 to move backward to reset so that the second fork 712 and the first fork 53 are overlapped and staggered in the left-right direction and the up-down direction. During the backward movement, the support plate 713 is simultaneously mounted on the first fork 53 and the second fork 712. When the second flipping mechanism 5 flips upward to reset, it drives the first fork 53 and the support plate 713 to flip upward, causing the support plate 713 to detach from the second fork 712. The above process is repeated during the next round of loading and unloading.

[0095] Because there are gaps between the first fork 53 and between the second fork 712 and the first fork 53, a support plate 713 is installed on the first fork 53 and the second fork 712 to make the contact surface for supporting the goods a complete flat surface. Using the support plate 713 to support goods is particularly suitable for loading and unloading bulk goods. The support plate 713, the first fork 53, and the second fork 712 are all detachable and can be freely switched according to the type of goods to be loaded or unloaded, making it flexible in use. The detachable installation method of the support plate 713 to the first fork 53 and the second fork 712 can be threaded connection, snap-fit ​​connection, etc., with snap-fit ​​connection being preferred for ease of installation and disassembly during use. Bulk goods refer to goods that are not supported by wooden pallets. The first fork 53 and the second fork 712 share a support plate 713. During both the flipping process of the second tilting mechanism 5 and the unloading process of the support assembly 71 entering the carriage, the goods remain on the support plate 713. The passage gap 52 is smaller than the length of the goods in the left and right directions to prevent the goods from falling out of the passage gap 52.

[0096] Furthermore, the second fork 712 is provided with a first fixing member 7121 on both the left and right sides, which is narrower at the top and wider at the bottom. The bottom surface of the support plate 713 is provided with a fixing unit corresponding to the second fork 712. The fixing unit includes two opposing second fixing members 7131. Both second fixing members 7131 are narrower at the bottom and wider at the top. The distance W1 between the two second fixing members 7131 in one fixing unit is greater than or equal to the distance W2 between the left and right sides of the second fork 712, so that when the support plate 713 is installed on the second fork 712, the first fixing member 7121 and the second fixing member 7131 are engaged.

[0097] like Figure 4 As shown, W1≥W2, so that when the second fork 712 and the support plate 713 are installed, the first fixing member 7121 and the second fixing member 7131 engage. The first fixing member 7121, which is narrow at the top and wide at the bottom, and the second fixing member 7131, which is narrow at the bottom and wide at the top, facilitate the quick installation of the support plate 713 onto the second fork 712 in the vertical direction.

[0098] Furthermore, the first fixing member 7121, near the second fixing member 7131, is provided with a guide surface 71211, a first vertical surface 71212, a first inclined surface 71213, and a second vertical surface 71214 from top to bottom. The second fixing member 7131, near the first fixing member 7121, is provided with a third vertical surface 71311, a second inclined surface 71312, and a fourth vertical surface from top to bottom. This ensures that after the first fixing member 7121 and the second fixing member 7131 are engaged, the first vertical surface 71212 abuts against the third vertical surface 71311, the first inclined surface 71213 abuts against the second inclined surface 71312, and the second vertical surface 71214 abuts against the fourth vertical surface.

[0099] By setting the first vertical surface 71212, the first inclined surface 71213, and the second vertical surface 71214 to abut against the third vertical surface 71311, the second inclined surface 71312, and the fourth vertical surface respectively, the connection between the support plate 713 and the second fork 712 can be made stable and not easily loosened or detached when moving back and forth. At the same time, the guide surface 71211 can facilitate the engagement of the first fixing member 7121 and the second fixing member 7131 in the vertical direction. When it is necessary to remove the support plate 713 from the second fork 712, it is only necessary to pull the support plate 713 upward to separate the support plate 713 from the second fork 712.

[0100] The bottom surface of the support plate 713 is provided with a guide member 7136, which is located in front of the second fork 712. The guide member 7136 is narrow at the bottom and wide at the top. When the second flipping mechanism 5 flips downward, the guide member 7136 facilitates the installation of the support plate 713 and the second fork 712. The shape of the guide member 7136, which is narrow at the bottom and wide at the top, serves as a guide.

[0101] Furthermore, the lower surface of the support plate 713 extends downward to form an abutment portion 7132, such that when the support plate 713 is installed on the first fork 53, the abutment portion 7132 abuts against the front end of the first fork 53.

[0102] The abutment part 7132 abuts against the front end of the first fork 53, improving the stability of the two during installation. Especially when the second flipping mechanism 5 drives the first fork 53 to flip upward, the abutment part 7132 can better prevent the support plate 713 from slipping during the upward flipping process, thus ensuring the stability of the equipment operation.

[0103] Furthermore, the lower surface of the support plate 713 is provided with a plug-in unit corresponding to the first fork 53. The plug-in unit includes at least two oppositely arranged plug-in members 7133. Both plug-in members 7133 are narrower at the back and wider at the front. A plug-in gap 7134 is left between the two plug-in members 7133. The width W3 of the plug-in gap 7134 is greater than or equal to the width W4 between the left and right sides of the first fork 53, so that when the support plate 713 is installed on the first fork 53, the first fork 53 is inserted into the plug-in gap 7134.

[0104] The connector 7133 facilitates the installation of the support plate 713 onto the first fork 53 while preventing misalignment between the first fork 53 and the support plate 713 in the lateral direction. By setting the connector 7133 and the insertion gap 7134, it is easy to reinstall the support plate 713 onto the first fork 53 while the second fork 712 is unloading goods and resetting, resulting in high installation efficiency. When it is necessary to remove the support plate 713 from the first fork 53, simply pull the support plate 713 forward to separate it from the first fork 53.

[0105] Furthermore, the bottom surface of the front end of the aforementioned support plate 713 is provided with an inclined member 7135 to facilitate the removal of the aforementioned support plate 713 from the cargo compartment of the aforementioned truck under the cargo, and the aforementioned inclined member 7135 is inclined downward from front to back.

[0106] The tilting component 7135 facilitates the support plate 713 to exit under the goods when the goods are lowered with the second fork 712, avoiding the support plate 713 from scraping and wearing against the bottom of the carriage during the process of exiting under the goods, avoiding wear on the front end of the support plate 713, and avoiding damage to the bottom of the carriage, thus extending the service life of the support plate 713.

[0107] Furthermore, the aforementioned moving component 6 includes a first rotary drive 61, a first gear 62, a first rack 63, a first guide rail 64, a moving bracket 65, and a plurality of first sliders 66. At least two of each of the first gear 62, the first rack 63, and the first guide rail 64 are provided. The first guide rail 64 is disposed on the first frame 1 along the front-rear direction. Each of the first sliders 66 is slidably disposed on the first guide rail 64. The moving bracket 65 is disposed on the first sliders 66. The first rack 63 is provided on the outer side walls of both the left and right sides of the moving bracket 65. The first rotary drive 61 is disposed on the first frame 1. The first gear 62 is connected to the output end of the first rotary drive 61, and the first gear 62 meshes with the first rack 63.

[0108] The movement of the movable support 65 can be stably controlled by the first guide rail 64, the first slider 66, the first gear 62, and the first rack 63. The first guide rail 64 and the first slider 66 ensure that the running trajectory of the movable support 65 does not deviate, and the first gear 62 and the first rack 63 accurately control the stroke of the movable support 65. During operation, the first rotary drive 61 drives the first gear 62 to rotate, thereby driving the first rack 63, the movable support 65, and the support frame to move along the first guide rail 64. Several movable wheels 67 are provided on the left and right sides of the bottom front end of the movable support 65, making it easy for the movable support 65 to move in the carriage, reducing wear between the movable support 65 and the carriage, and extending the service life of the movable support 65. Furthermore, the movable wheels 67 are embedded in the bottom surface of the movable support 65 to reduce the height of the movable wheels 67 and the movable support 65, making it easier to fill the space inside the carriage with goods. The movable wheels 67 are rollers.

[0109] Furthermore, the aforementioned support drive assembly 711 includes a second rotary drive 7111, a second gear 7112, a second rack 7113, a second guide rail 7114, and a plurality of second sliders 7115. At least two of each of the second gear 7112, the second rack 7113, and the second guide rail 7114 are provided. The second guide rail 7114 is disposed on the movable bracket 65 along the front-rear direction. Each of the second sliders 7115 is slidably disposed on the second guide rail 7114. The support frame 73 is disposed on the second sliders 7115. The second rack 7113 is provided on the inner sidewalls of both the left and right sides of the movable bracket 65. The second rotary drive 7111 is disposed on the support frame 73. The second gear 7112 is connected to the output end of the second rotary drive 7111, and the second gear 7112 meshes with the second rack 7113.

[0110] The movement of the support frame 73 can be stably controlled by the second guide rail 7114, the second slider 7115, the second gear 7112, and the second rack 7113. The second guide rail 7114 and the second slider 7115 ensure that the running trajectory of the support frame 73 does not deviate. The second gear 7112 and the second rack 7113 accurately control the stroke of the support frame 73. During operation, the second rotary drive 7111 drives the second gear 7112 to rotate, thereby driving the second rack 7113, the support frame 73, and the supporting component 71 and pushing component 72 on the support frame 73 to move along the second guide rail 7114.

[0111] Furthermore, the aforementioned first flipping mechanism 3 includes a first flipping bracket 31 and a first flipping drive 32. The first part 311 and the second part 312 of the first flipping bracket 31 are arranged at an angle with their openings facing backward. The second part 312 is hinged to the second frame 2. The first frame 1 is provided with the first flipping drive 32, and the output end of the first flipping drive 32 is connected to the second part 312 in a transmission manner. The second part 312 is provided with a first rolling assembly 33. The first rolling assembly 33 includes a fourth rotation drive 331, a first transmission belt 332, and several rolling units. The rolling unit includes a roller 333, a transmission rod 334, and two first transmission wheels 335. The roller 333 is sleeved on the transmission rod 334. The aforementioned transmission rod 334 is rotatably mounted on the aforementioned second part 312. The two aforementioned first transmission wheels 335 are respectively sleeved on both ends of the aforementioned transmission rod 334. At least two aforementioned first transmission belts 332 are provided. The aforementioned first transmission belts 332 are wound around the output ends of the aforementioned first transmission wheels 335 and the aforementioned fourth rotary drive 331. When the aforementioned first part 311 is placed with goods, the aforementioned roller 333 abuts against the goods. The aforementioned third part 511 and fourth part 512 of the aforementioned second flipping bracket 51 are arranged at an angle with the opening facing forward. The aforementioned fourth part 512 is provided with a second rolling assembly. The aforementioned second rolling assembly has the same structure as the aforementioned first rolling assembly 33. The height H1 of the aforementioned fourth part 512 is greater than the height H2 of the aforementioned second part 312.

[0112] The first part 311 and the second part 312 are preferably arranged vertically. When arranged vertically, the first part 311 is parallel to the ground, which facilitates the transport of goods onto the first part 311 by forklifts or intelligent warehousing systems. Then, the first flipping drive 32 drives the second part 312 to flip upward, thereby causing the first part 311 and the goods to flip upward. The third part 511 and the fourth part 512 are preferably arranged at an angle of 85° to 89° with their openings facing forward, so that the third part 511 is slightly tilted upward. The upward tilt of the third part 511 has two advantages. First, when the second flipping mechanism 5 drives the first fork 53 to flip upward, it is easier for the first fork 53 to hook the support plate 713 upward, which facilitates the separation of the support plate 713 from the second fork 712. Second, when the second flipping mechanism 5 drives the first fork 53 and the horizontally stacked goods to flip downward together, the tilted third part 511 can improve the gripping force and friction of the goods under the action of gravity, ensuring the stability of the goods during the flipping process. The first flipping mechanism 3, the conveying mechanism 4, and the second flipping mechanism 5 work together to achieve vertical stacking of goods, avoiding worker injuries and improving loading and unloading efficiency. When the height H1 of the fourth part 512 is greater than the height H2 of the second part 312, the fourth part 512 can effectively stack goods and provide support for the goods on top after flipping. The height H1 is adjusted adaptively according to the height inside the carriage. Before the second flipping mechanism 5 flips downward, the fourth part 512 is flush with the conveying mechanism 4 to support the goods. At this time, the second part 312 faces upward to hold the goods in place. As more goods are conveyed by the conveying mechanism 4, goods are stacked horizontally on the fourth part 512. After the second flipping mechanism 5 flips downward, vertically stacked goods are obtained.

[0113] A first rolling assembly 33 is provided in the second part 312 and a second rolling assembly is provided in the fourth part 512 to further improve the efficiency of cargo transportation and prevent cargo from being stuck on the second part 312 and the fourth part 512. The first transmission belt 332 and the transmission bar 43 are belts or chains, preferably chains.

[0114] Furthermore, it also includes a movable flipping and protective material mechanism 8, which is used to abut the goods from the left and right sides when the goods are flipped. The flipping and protective material mechanism 8 is disposed on the second frame 2 near the first flipping mechanism 3 and / or the second flipping mechanism 5. The flipping and protective material mechanism 8 includes a first clamping assembly 81 and a second clamping assembly 82. The first clamping assembly 81 includes a first clamping arm 811, a protective material plate 812, and a first clamping drive 813. The first clamping arm 811 includes a first segment 8111 and a second segment 8112. 112, the first segment 8111 and the second segment 8112 are arranged at an angle with their openings facing the goods. The protective plate 812 is connected to the first segment 8111, and the second segment 8112 is hinged to the second frame 2. The lower side of the second segment 8112 is connected to the first clamping drive 813, so that the protective plate 812 moves closer to or away from the goods under the drive of the first clamping drive 813. The second clamping assembly 82 has the same structure as the first clamping assembly 81 and is symmetrically arranged on the left and right sides of the goods.

[0115] Both the first flipping mechanism 3 and the second flipping mechanism 5 can be equipped with a flipping protective material mechanism 8. When the first clamping drive 813 of the first clamping assembly 81 and the second clamping assembly 82 extends or retracts, it drives their respective first clamping arms 811 and protective plates 812 to move closer to or further away from the goods to hold the goods against the left and right sides, preventing the goods from falling off the left and right sides during the flipping process. The first section 8111 and the second section 8112 are set at an angle with their openings facing the goods, which can provide greater support when holding the goods against them.

[0116] Furthermore, the aforementioned conveying mechanism 4 includes a third rotary drive 41, a second transmission wheel 42, a transmission bar 43, a main transmission shaft 44, a secondary transmission shaft 45, and several chain plates 46. At least one main transmission shaft 44 and at least one secondary transmission shaft 45 are provided, and both are rotatably connected to the second frame 2. The third rotary drive 41 is mounted on the second frame 2 and is drively connected to the main transmission shaft 44. At least four second transmission wheels 42 are provided, each sleeved on the main transmission shaft 44 and the secondary transmission shaft 45. At least two transmission bars 43 are provided, each winding around the second transmission wheels 42 of the main transmission shaft 44 and the second transmission wheels 42 of the secondary transmission shaft 45. Both ends of each chain plate 46 are fixedly connected to two transmission bars 43.

[0117] The third rotary drive 41 drives the main drive shaft 44 to rotate, thereby driving the second drive wheel 42 on the main drive shaft 44, the drive bar 43, the second drive wheel 42 on the auxiliary drive shaft 45, and the chain plate 46 to rotate, thus achieving the effect of transporting goods.
