Description

Technical Field

[0001] The present invention belongs to the technical field of unit cargo unitized logistics technology and the overall loading of unit cargo into a vehicle, and specifically relates to an operation system and method for stacking unit cargo in a vehicle in which multiple units of cargo are assembled in multiple horizontal and vertical directions. Background Art

[0002] According to national standards, unit load is defined as a group of goods or packages assembled together through one or more means to form a complete unit for easy loading, unloading, transportation, stacking, and storage. A palletized unit is defined as a unit load combined with a pallet. Packaged items are stacked together on a pallet and properly secured to facilitate mechanical loading, unloading, and transportation. Based on this definition, a unit load is a complete stack of goods on a pallet, without the pallet.

[0003] At present, unitized logistics technology based on palletized containers has been widely used in logistics operations at home and abroad. For example, in factory automated production and logistics warehousing systems, unitized logistics automation operations based on standard pallets have covered the entire internal logistics process.

[0004] However, in the loading and unloading and transportation stages of product distribution, particularly in long-distance and export transport, and in logistics and transportation operations that require high vehicle and container load rates, low freight costs, low energy consumption, and low pollution, the use of unitized logistics technology, using palletized units for loading and unloading operations, will lead to problems such as reduced vehicle load rates, increased pallet costs, or difficulty in recycling. This will lead to significant increases in transportation and pallet costs, as well as additional energy consumption and pollution. Therefore, to date, in order to save logistics costs, the vast majority of companies have abruptly abandoned palletized unitization operations when shipping products or goods, and instead resort to manual loading and unloading of goods piece by piece, transporting goods without pallets.

[0005] However, there are also many disadvantages in manually loading goods one by one or using conveyors with manual cooperation to load goods one by one, including: high labor consumption, low efficiency of the logistics system, poor operation quality, high rate of damage to goods or packaging, affecting the image of products and enterprises, and being unable to adapt to the business needs of continuous growth in production and sales.

[0006] Even though pallets are widely used in logistics operations today, the vast majority of ordinary products or goods still use manual loading and unloading operations. This is a helpless choice for companies because manual loading and unloading operations of individual pieces at the expense of work efficiency and quality can greatly increase the actual load rate of vehicles or containers, save pallet costs or pallet recycling problems, and save companies a lot of logistics costs.

[0007] Today, the widespread pain points and defects of using palletized transportation, or the bottlenecks and disadvantages of using non-palletized transportation and manual loading and unloading of individual pieces, have long been and will continue to be a problem for the logistics industry, affecting and restricting the reduction of energy consumption and increase of efficiency in social logistics activities. Summary of the Invention

[0058] Example 1

[0059] According to national standards, the planar dimensions of a unit load are 1200 x 1000, meaning the cross-section of the unit load is rectangular, encompassing both length and width. In this embodiment, unit loads transported along the length of the unit load are referred to as longitudinal unit loads, while unit loads transported along the width of the unit load are referred to as transverse unit loads.

[0060] A method for stacking unit cargo in multiple horizontal and vertical directions to form a complete vehicle, comprising the following steps:

[0061] P1. Place the first longitudinal unit load and the first transverse unit load on the longitudinal belt conveyor line 221 and the transverse belt conveyor line 222, respectively. The longitudinal belt conveyor line 221 and the transverse belt conveyor line 222 are parallel to each other with a gap therebetween. Then, place the second longitudinal unit load and the second transverse unit load on the longitudinal belt conveyor line 221 and the transverse belt conveyor line 222, respectively. Repeat this process multiple times until the longitudinal belt conveyor line 221 and the transverse belt conveyor line 222 are fully covered with unit loads.

[0062] P2. Move the longitudinal belt conveyor line 221 and the transverse belt conveyor line 222 closer together so that the left and right rows of unit cargo are pressed together to form a stacked unit with the front and back being flush;

[0063] P3. Eliminate the horizontal gap between the pieces of cargo in the cargo stack unit and make the two outer side surfaces of the cargo stack unit flush.

[0064] P4, after the two outer sides are aligned, the assembled cargo stack units are transported as a whole to assemble the entire cargo stack of the vehicle;

[0065] P5. Repeat steps P1-P4 until the stacking units are assembled into a complete stack of cargo for the entire vehicle according to the loading design.

[0066] By implementing the method of combining unit cargo in multiple horizontal and vertical directions into a whole vehicle cargo stack of this embodiment, multiple unit cargoes can be first combined into a multi-horizontal and multi-vertical combined cargo stack unit, and then combined into a whole vehicle cargo stack. In addition, during the combined transportation process of the unit cargoes combined into a multi-horizontal and multi-vertical combined cargo stack unit, the collision and interference between adjacent unit cargo stacks is avoided.

[0067] Example 2

[0068] like Figure 1 As shown, the multi-horizontal and multi-vertical unit cargo stacking operation system includes a unit cargo transfer and conveying vehicle 1, a multi-horizontal and multi-vertical conveying and collecting platform 2, a unit sorting device for the collected cargo stack 3, and a vehicle-wide collection and loading platform 4 for the collected cargo stack. The unit cargo transfer and conveying vehicle 1 is generally slender and linear, and is located between the depalletizing station 01 and the multi-horizontal and multi-vertical conveying and collecting platform 2. It is used to dynamically connect the depalletizing station 01 with the input end of the multi-horizontal and multi-vertical conveying and collecting platform 2. The unit sorting device for the collected cargo stack 3 is located on both sides of the multi-horizontal and multi-vertical conveying and collecting platform 2. The output end of the multi-horizontal and multi-vertical conveying and collecting platform 2 is connected to the vehicle-wide collection and loading platform 4 for the collected cargo stack. The following is a further detailed introduction to each of the above components.

[0069] like Figure 2 and Figure 2.1 As shown, the unit cargo transfer vehicle 1 comprises a transfer vehicle body 10, a flat top chain conveyor device 11, a transfer motion transmission device 12 and a transfer vehicle slide rail 13. The plane size of the unit cargo transfer vehicle 1 is related to the plane size of the unit cargo pallet.

[0070] The transfer vehicle rails 13 are elongated and linear, with pallet removal stations 01 located at either end, away from the multi-transverse and multi-vertical transport platform 2. In this embodiment, two transfer vehicle bodies 10 are provided, each reciprocating between a corresponding pallet removal station 01 and the input end of the multi-transverse and multi-vertical transport platform 2.

[0071] The transfer vehicle body 10 is the main structure of the unit load transfer vehicle 1. The flat-top chain conveyor 11 and the transfer transmission 12 are both mounted on the transfer vehicle body 10. The transfer vehicle body 10 is slidably mounted on the transfer vehicle rails 13 via a lower movable slider 120. Driven by the transfer transmission 12, the transfer vehicle body 10 can reciprocate along the length of the transfer vehicle rails 13.

[0072] like Figure 2.1As shown, the flat-top chain conveyor device 11 includes a flat-top conveyor chain 110, a conveyor assembly 111, and a conveying power 112. The flat-top conveyor chains 110 are mounted on the upper portion of the transfer vehicle body 10, and there are multiple of them. The conveying power 112 is mounted on the lower portion of the transfer vehicle body 10. The conveying power 112 drives the flat-top conveyor chains 110 through the conveyor assembly 111 to perform bidirectional conveying in a direction perpendicular to the length of the transfer vehicle slide rail 13.

[0073] The transfer transmission device 12 includes a moving slider 120, a moving power 121 and a moving kit 122. The moving slider 120 is arranged at the lower part of the transfer vehicle body 10 and is slidably connected to the transfer vehicle slide rail 13. Specifically, the moving kit 122 includes a driving gear 1221 and a moving rack 1222, wherein the driving gear 1221 is fixedly connected to the output shaft of the moving power 121, the moving rack 1222 is fixedly connected to the transfer vehicle slide rail 13, and the driving gear 1221 and the moving rack 1222 are meshed with each other. The mobile power 121 drives the driving gear 1221 of the moving kit 122 to mesh with the moving rack 1222 provided on the transfer vehicle slide rail 13, so that the transfer vehicle body 10 moves back and forth on the transfer vehicle slide rail 13.

[0074] The transfer vehicle slide 13 comprises a slide frame 131 and two movable slides 132. The two movable slides 132 are arranged parallel to each other on either side of the slide frame 131. The movable rack 1222 of the transfer motion transmission device 12 is located below one of the movable slides 132. The movement direction of the unit cargo transfer vehicle 1 is perpendicular to the conveying direction of the flat-top conveyor chain 110.

[0075] The unit load transfer vehicle 1 operates by dynamically connecting the output of the depalletizing station 01 and the input of the multi-transverse and multi-vertical transport and aggregation platform 2 via the transfer vehicle's slide rails 13. The unit load transfer vehicle 1 reciprocates on the transfer vehicle's slide rails 13, transferring depalletized unit loads from the output of the depalletizing station 01 to the unit load transfer vehicle 1. The unit loads are then transported to the multi-transverse and multi-vertical transport and aggregation platform 2, where they are assembled into stacked units.

[0076] Figure 3 、 Figure 3.1 、 Figure 3.2The figure is a schematic diagram of an embodiment of a multi-horizontal and multi-vertical conveying collection platform 2. As can be seen from the figure, the multi-horizontal and multi-vertical conveying collection platform 2 is a collection platform equipped with two rows of 11 unit cargo conveying lines, each with five sections arranged vertically and six sections arranged horizontally. It includes a vertical and horizontal line integral frame 220, a longitudinal belt conveyor line 221, and a transverse belt conveyor line 222. The longitudinal belt conveyor line 221 is provided in five sections and is fixedly mounted on one side of the vertical and horizontal line integral frame 220, while the transverse belt conveyor line 222 is provided in six sections and is laterally slidably mounted on the other side of the vertical and horizontal line integral frame 220. The total length of the six transverse belt conveyor lines 222 is the same as the total length of the five longitudinal belt conveyor lines 221. The upper plane of the multi-horizontal and multi-vertical conveying collection platform 2 is related to the plane dimensions of the multi-horizontal and multi-vertical collection cargo stack unit.

[0077] Since the plane size of the unit cargo of my country's standard pallet is 1200*1000, by combining the unit cargo in 5 vertical and 6 horizontal directions, we can obtain an overall 6-meter-long 5 vertical and 6 horizontal collection cargo stack unit with a total of 11 stacks of unit cargo, so as to further realize the overall cargo stack collection of the whole vehicle and carry out the overall loading operation of the whole vehicle.

[0078] It is understood that, in the present application, the longitudinal belt conveyor lines 221 and the transverse belt conveyor lines 222 may be provided with other numbers other than 5 and 6 according to actual usage. For example, the longitudinal belt conveyor lines 221 and the transverse belt conveyor lines 222 may be provided with 6 and 7 sections, or 7 and 8 sections, etc., respectively. As long as the assembled cargo stack unit composed of multiple longitudinal belt conveyor lines 221 and multiple transverse belt conveyor lines 222 has a flat rectangular parallelepiped or cube shape, it will be sufficient.

[0079] In this embodiment, the longitudinal direction refers to a direction perpendicular to the slide rail 13 of the transfer vehicle, and the transverse direction refers to a direction parallel to the slide rail 13 of the transfer vehicle.

[0080] like Figure 3.1 As shown, during operation, according to the needs of the operation steps, the horizontal belt conveyor line 222 can be separated from the vertical belt conveyor line 221. After separation, the two conveyor lines can independently transport unit goods. Because there is a gap between the two lines, the transported goods stacks of the two lines will not scrape or interfere with each other during independent transportation.

[0081] Depend on Figure 3-Figure 3.2 As can be seen, the vertical and horizontal line integral frame 220 includes vertical legs, horizontal rods (not marked in the figure), and conveyor line slide rails 2201. Among them, the conveyor line slide rails 2201 are horizontally arranged on the upper plane of the vertical and horizontal line integral frame 220 on one side of which 6 horizontal section belt conveyor lines 222 are installed.

[0082] See Figure 3 、 Figure 3.2The longitudinal belt conveyor line 221 is arranged in five sections in sequence, and each longitudinal belt conveyor line 221 includes a longitudinal belt line frame 2210, a longitudinal conveyor belt 2211 and a longitudinal conveyor line dynamic transmission device 2212.

[0083] See Figure 3 、 Figure 3.2 、 Figure 3.3 The horizontal belt conveyor line 222 is arranged in 6 sections in sequence. Each section of the horizontal belt conveyor line 222 includes a horizontal belt line frame 2220, a horizontal conveyor belt 2221, a horizontal conveyor line dynamic transmission device 2222, and a conveyor line slider 2223. A double-connected long rod 2224 and a push-pull cylinder 2225 are also provided at the lower part of the horizontal belt conveyor line 222.

[0084] There are multiple conveyor line sliders 2223, each fixedly mounted on each horizontal belt conveyor line 222, and cooperating with the conveyor line slide rails 2201 on the vertical and horizontal line integral frame 220. There are two double-connecting long rods 2224, both extending in the longitudinal direction, used to securely connect the six horizontal belt conveyor lines 222 together.

[0085] Push-pull cylinders 2225 are symmetrically positioned beneath two of the horizontal belt conveyor sections 222, acting as a mechanism for sliding the horizontal belt conveyor sections 222 together. The cylinders 2225 are fixedly connected to the dual-connecting rods 2224 via supports. The telescopic ends of the cylinders 2225 are connected to the vertical and horizontal belt conveyor frame 220. The push-pull motion of the cylinders 2225 causes the six horizontal belt conveyor sections 222 to slide laterally on the vertical and horizontal belt conveyor frame 220, allowing the six horizontal belt conveyor sections 222 to separate from or align with the five vertical belt conveyor sections 221.

[0086] The operating principle of the multi-horizontal and multi-vertical conveying and collection platform 2 is that in the unit cargo collection operation, since the horizontal belt conveyor line 222 and the longitudinal belt conveyor line 221 are separated, the unit cargo transfer conveying vehicle 1 is used to input them simultaneously or separately, and the longitudinal belt conveyor line 221 and the horizontal belt conveyor line 222 can respectively perform the longitudinal conveying and collection operations of their own conveyor lines without interfering with each other; when the longitudinal conveying and collection of the two columns are completed, the horizontal belt conveyor line 222 and the longitudinal belt conveyor line 221 are pressed against each other, and the two columns of collected unit cargo on the horizontal belt conveyor line 222 and the longitudinal belt conveyor line 221 are brought together to form an integral 5-vertical and 6-horizontal collection cargo stack unit.

[0087] like Figure 4As shown, the stacking unit assembly device 3 includes a gantry 30, a cleat 31, and a clamping cylinder 32. Both the cleat 31 and the clamping cylinder 32 are mounted on the gantry 30. It will be appreciated that in this embodiment, the cylinder can also be replaced with a power device such as a motor. Furthermore, depending on operational needs, the stacking unit assembly device 3 can be arranged in a single group or in sections.

[0088] The device's gantry support 30 spans both sides and above the multi-transverse and multi-vertical conveying and aggregation platform 2 and comprises gate posts 301, transverse tie rods 302, and longitudinal tie rods 303. Two or more sets of gate posts 301 are positioned along the outer sides of the multi-transverse and multi-vertical conveying and aggregation platform 2, with their lower ends fixed to the ground. The two sets of gate posts 301 are connected by transverse tie rods 302 and longitudinal tie rods 303.

[0089] The sorting clamps 31 are arranged vertically and symmetrically on the two inner sides of the device door-shaped bracket 30 along the longitudinal center line of the multi-horizontal and multi-vertical conveying collection platform 2. After installation, the inner opposite distance between the sorting clamps 31 on both sides is greater than the width of the overall cargo stack of the unit cargo collection stack.

[0090] Specifically, the finishing clamp 31 includes a clamp 311, a clamp panel 312, a clamp rear frame 313, and an intermediate shear frame 314. The inner side of the clamp 311 is covered with the clamp panel 312, which is preferably made of an elastic material. The outer side of the clamp 311 is fixedly connected to the clamp rear frame 313, which is in turn connected to the intermediate shear frame 314. The upper two shear frame ends of the intermediate shear frame 314 are hinged to the upper portion of the door post 301 and the upper portion of the clamp rear frame 313, respectively. The lower two shear frame ends of the intermediate shear frame 314 are slidably disposed in slide slots 315 on the lower portion of the door post 301 and the lower portion of the clamp rear frame 313, respectively.

[0091] The clamping cylinder 32 is installed between the intermediate shear frame 314 and the device gate-shaped bracket 30 , the fixed end of the clamping cylinder 32 is fixedly set on the device gate-shaped bracket 30 , and the output end of the clamping cylinder 32 is connected to the intermediate shear frame 314 .

[0092] The main function of the collective cargo stack unit sorting device 3 is to use the collective cargo stack unit sorting device 3 to clamp and sort the two side surfaces of the collective cargo stack unit after the unit cargo is gathered into the collective cargo stack unit on the multi-horizontal and multi-vertical conveying collection platform 2, so as to eliminate the gaps between the piece cargo and the protruding piece cargo on both sides of the overall cargo stack of the collective cargo stack unit, so as to make the two sides of the overall cargo stack of the collective cargo stack unit flat and consistent, so as to further gather the overall cargo stack of the collective cargo stack unit on the overall cargo stack collection loading platform 4 of the entire vehicle, so as to meet the requirements of entering the overall loading operation state of the entire vehicle.

[0093] Depend on Figure 5 As can be seen, the truckload-mounted, integrated cargo stack assembly loading platform 4 includes a transporting, moving, and transposing device 40 and a platform elevating chassis 41. The transporting, moving, and transposing device 40 is mounted on the platform elevating chassis 41. Its input is dynamically connected to the output of the multi-transverse and multi-vertical transport assembly platform 2, and it can perform longitudinal reciprocating motion on the platform elevating chassis 41 and onto the vehicle floor. The top surface dimensions of the transporting, moving, and transposing device 40 are related to the bottom surface dimensions of the integrated truckload-mounted, integrated cargo stack.

[0094] exist Figure 5 In the figure, the collective conveying and moving transposition device 40 is in an "I" shape as a whole, including a whole vehicle cargo stack collective conveyor line 401, an output transposition loading front tongue 402, a movable roller (not marked in the figure), and a movable dynamic transmission device (not marked in the figure). Among them, the whole vehicle cargo stack collective conveyor line 401 is in a slender and straight shape as a whole, the output transposition loading front tongue 402 is arranged at the front end of the whole vehicle cargo stack collective conveyor line 401 along the length direction of the whole vehicle cargo stack collective conveyor line 401, and the movable roller is arranged at the bottom of the collective conveying and moving transposition device 40. The movable dynamic transmission device is a dynamic transmission device that allows the collective conveying and moving transposition device 40 to move back and forth on the platform lifting chassis 41. The movable dynamic transmission device is arranged at the bottom of the platform lifting chassis 41 and is connected to the bottom of the collective conveying and moving transposition device 40 by a transmission chain.

[0095] Specifically, the whole vehicle stack collection conveyor line 401 includes a whole vehicle conveyor line structure 4010, a multi-row flat top chain conveyor line 4011, and a flat top chain conveyor line dynamic transmission device 4012. The multi-row flat top chain conveyor line 4011 is arranged on the whole vehicle conveyor line structure 4010 and connected to the flat top chain conveyor line dynamic transmission device 4012.

[0096] The output transposition loading front tongue 402 is located at the front end of the vehicle-mounted, stacked assembly conveyor line 401. The output transposition loading front tongue 402 has a wedge-shaped longitudinal cross-section with a thin front end. The top plane of the output transposition loading front tongue 402 can be switched between a horizontal plane and a forward-inclined plane. When the top plane of the output transposition loading front tongue 402 is horizontal, it is flush with the top plane of the vehicle-mounted, stacked assembly conveyor line 401. Multiple free rollers (not labeled in the figure) are longitudinally arranged on the top of the output transposition loading front tongue 402.

[0097] exist Figure 5 In the figure, the platform lifting chassis 41 is generally L-shaped, specifically including a base frame structure 410, lifting legs 411, and a mast pushing device 412. Among them, the base frame structure 410 is generally slender and straight, and the mast pushing device 412 is vertically fixed to the tail end of the base frame structure 410.

[0098] A plurality of lifting legs 411 are installed at the lower portion of the chassis structure 410 , and the chassis structure 410 is fixedly mounted on the ground through the lifting legs 411 . The lifting legs 411 can adjust the height of the entire vehicle's cargo stack assembly loading platform 4 .

[0099] The operation process of the whole vehicle cargo stack collection loading platform 4 is to input the multi-horizontal and multi-vertical collection cargo stack units sorted by the multi-horizontal and multi-vertical collection cargo stack unit sorting device 3 from the multi-horizontal and multi-vertical conveying and collecting platform 2 to the whole vehicle cargo stack collection loading platform 4 for whole vehicle cargo stack collection, and through two conveying and collecting operations, the multi-horizontal and multi-vertical collection cargo stack units are assembled into a whole vehicle cargo stack that meets the loading design requirements, so as to meet the requirements of entering the whole vehicle loading operation state.

[0100] Example 3

[0101] The method for stacking unit cargo in multiple horizontal and vertical directions into a complete vehicle cargo stacking system described in Example 2 includes the following steps:

[0102] X1. At the beginning of the operation, the two unit cargo transfer and conveying vehicles 1 are connected to the output ends of the corresponding unit cargo depalletizing stations 01, and the depalletized unit cargo is transported to the unit cargo transfer and conveying vehicles 1. Since the output ends of the two unit cargo depalletizing stations 01 always output unit cargo longitudinally or transversely, the unit cargo is always placed longitudinally or transversely on the unit cargo transfer and conveying vehicles 1; specifically, if the unit cargo is placed longitudinally on the unit cargo transfer and conveying vehicle 1, the unit cargo transfer and conveying vehicle 1 is always connected to the longitudinal belt conveyor line 221 of the multi-horizontal and multi-vertical conveying and collecting platform 2 for transportation; and if the unit cargo is placed transversely on the unit cargo transfer and conveying vehicle 1, it is always connected to the transverse belt conveyor line 222 of the multi-horizontal and multi-vertical conveying and collecting platform 2 for transportation.

[0103] X2. At the same time, the horizontal belt conveyor line 222 is pushed outward laterally by the push-pull cylinder 2225, that is, the horizontal belt conveyor line 222 and the vertical belt conveyor line 221 are separated to a set distance, so that the multi-horizontal and multi-vertical conveying collection platform 2 is separated into two columns of independent horizontal belt conveyor lines 222 and vertical belt conveyor lines 221.

[0104] X3. Move the unit cargo transfer and conveying vehicle 1 carrying the unit cargo placed longitudinally to the input end of the longitudinal belt conveyor line 221, so that the unit cargo placed longitudinally on the unit cargo transfer and conveying vehicle 1 is transported to the longitudinal belt conveyor line 221; at the same time, move the unit cargo transfer and conveying vehicle 1 carrying the unit cargo placed transversely to the input end of the transverse belt conveyor line 222, so that the unit cargo placed transversely on the unit cargo transfer and conveying vehicle 1 is transported to the transverse belt conveyor line 222.

[0105] X4. Move the two unit cargo transfer vehicles 1 back to the output ends of their respective unit cargo depalletizing stations 01 and repeat the above-mentioned operations of X1 and X3 to continue the unit cargo delivery and assembly. When the unit cargo delivery and assembly are completed, the front and rear of the unit cargo in this row must be close together. After completing five delivery and assembly, stop the delivery and assembly of the longitudinal belt conveyor line 221 and continue the delivery and assembly of the transverse belt conveyor line 222. That is, the longitudinal belt conveyor line 221 performs five delivery and assembly, and the transverse belt conveyor line 222 performs six delivery and assembly.

[0106] X5. Push the horizontal belt conveyor line 222 laterally toward the center line through the horizontal frame push-pull cylinder 2225, so that the horizontal belt conveyor line 222 is close to the vertical belt conveyor line 221. At the same time, the unit cargo on the horizontal belt conveyor line 222 is also close to the unit cargo on the vertical belt conveyor line 221, forming a multi-horizontal and multi-vertical aggregate cargo stack unit with 5 vertical and 6 horizontal stacks of unit cargo, a total of 11 stacks, when viewed from above.

[0107] X6. Operate the collective cargo stack unit sorting device 3 so that the sorting clamping plates 31 are pushed from both outer sides toward the center line under the action of the clamping cylinder 32. Under the push and clamping of the sorting clamping plates 31, the lateral gaps between the pieces of cargo in the multi-transverse and multi-vertical collective cargo stack units are eliminated and the two outer side surfaces of the multi-transverse and multi-vertical collective cargo stack units are flush; after the multi-transverse and multi-vertical collective cargo stack units are sorted, they can be transported as a whole to the whole vehicle integral cargo stack collection loading platform 4 for whole vehicle integral cargo stack collection.

[0108] X7. Repeat operations X1-P6 until the whole vehicle cargo stack is assembled on the whole vehicle cargo stack assembly loading platform 4 with multiple horizontal and vertical aggregate cargo stack units according to the loading design, so that the whole vehicle cargo stack assembly loading platform 4 can enter the whole vehicle cargo stack assembly loading process.

[0109] The system and method for aggregating unit cargo in multiple horizontal and vertical directions into a complete vehicle stack, provided by the present invention, can realize the transportation and aggregation of palletized unit cargo into a stack unit according to the loading design, and then further assemble the stack units into a complete vehicle stack of unit cargo, thereby realizing the complete loading operation of the complete vehicle. Compared with the existing technology, the technical solution of the present invention can achieve the unitization and aggregation of unit cargo loading and unloading operations, as well as the automation and intelligence of the unitization operation mode, ultimately achieving the beneficial effects of high efficiency, low consumption, and green emission reduction in logistics operations.

[0110] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, according to the concept of the present invention, many changes can be made in the specific implementation method and application scope. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of the present invention.
