[0002] The packaging and transportation of some chemical liquid products mainly adopts packaging barrels and then container loading and transportation. The packaging barrels are special plastic barrels, which can be quantitatively packed and convenient for subsequent handling and use. The operation of loading the divided barrels is carried out. At present, there are very few parts that can be automated to assist loading. It is mainly carried out manually and loaded with forklifts to assist manual loading. A few are assisted by mechanical arms to grasp and carry. For loading of larger trucks, a large amount of manpower is required, the labor intensity is high, the labor cost is high, and the loading efficiency is low. Therefore, strictly speaking, there is no automatic loading system device in the existing loading, and some existing mechanical devices used to assist loading have no obvious effect on improving efficiency and reducing labor intensity, and their use is limited, there are many inconveniences in use, and even they cannot be used at all. For example, the loading of barrels of goods mentioned above cannot be assisted by forklift trucks, and the mechanical arm grasping requires high-precision positioning requirements. In the existing loading environment, accuracy problems are prone to occur, affecting normal work. Therefore, it is still necessary to carry barrels manually. In view of this, the existing large-scale freight loading method needs to be improved, and there is an urgent need for an automated system device that can replace manual loading. The inventor of this case conducted in-depth research and development on the loading process, and thus this case was created. Summary of the invention

[0004] Another object of the present invention is to provide an efficient, stable, reliable and automated loading method for the above-mentioned food phosphoric acid barrel loading system.

[0005] To achieve the above object, the technical solution of the present invention is: a food phosphoric acid barrel loading system, which includes an arranged conveyor line for conveying barrels, a multi-row carrier capable of carrying multiple rows of barrels at the same time, a single-row shaping and pushing device for conveying and arranging barrels in a single row according to quantity and pushing them onto the multi-row carrier, and a carrier lift for carrying and lifting the multi-row carrier; the single-row shaping and pushing device includes a single-row input line, a single-row transposition and pushing mechanism, a single-row lifting platform, and a single-row boarding and pushing mechanism. One end of the single-row input line is provided with a positioning blocking component, and the other end is the input end connected to the output end of the arranged conveyor line. The single-row lifting platform is arranged on one side of the single-row input line. The single-row transposition and pushing mechanism is arranged on the other side of the single-row input line opposite to the single-row lifting platform for pushing the single-row barrel onto the single-row lifting platform. The single-row boarding and pushing mechanism is arranged below the single-row input line and corresponding to one side of the single-row lifting platform for pushing the single-row barrel on the single-row lifting platform onto the multi-row carrier; the carrier lift is arranged on the other side of the single-row lifting platform opposite to the single-row boarding and pushing mechanism, and its upper surface is the working surface for carrying the multi-row carrier; the multi-row carrier runs back and forth between the carrier lift and the freight car body to work. The multi-row carrier includes a gantry body, multiple layers of barrel placement layers arranged at intervals up and down in the gantry body, and a lifting and pushing and stacking mechanism arranged on the gantry body on the side of the barrel placement layer facing the single-row lifting platform and capable of lifting and corresponding to each layer of barrel placement layer. The lifting and pushing and stacking mechanism is used to push the whole row of barrels on the barrel placement layer to the corresponding position in the car body for stacking.

[0006] On the pushing side edges of the single-row input line, the single-row lifting platform, and the barrel placement layer, a turning plate is hinged. A turning drive mechanism is arranged between the turning plate and the single-row input line, the single-row lifting platform, or the barrel placement layer. When turned to the vertical direction, it serves as an entry limit blocking plate on the pushing side of the single-row input line, the single-row lifting platform, or the barrel placement layer. When the turning plate is turned downward, it serves as a connection and transition plate for barrel pushing. The hinged opposite side edge of the connection and transition plate is a connection and placement flat edge.

[0007] The multi-row carrier is provided with a stable connection mechanism for connecting with the carrier lift or the bottom surface of the freight car body, and / or, the multi-row carrier is provided with a sensing and positioning device for running and positioning.

[0008] The stable connection mechanism includes an electromagnetic connection device connected to the lower part of the multi-row carrier through a lifting drive mechanism. The electromagnetic connection device includes multiple electromagnetic blocks that can be independently adsorbed and connected.

[0009] A guide rail guiding mechanism is provided between the bottom of the multi-row carrier vehicle and the carrier vehicle lifting platform, and between the ground from the carrier vehicle lifting platform to the freight car body and the bottom of the multi-row carrier vehicle. The part of the guide rail guiding mechanism on the carrier vehicle lifting platform and the ground can be disconnected. The guide rail on the ground between the carrier vehicle lifting platform and the freight car body can be of a multi-section combination type, and is installed on the ground through a telescopic driving mechanism and can extend into or retract along the inner bottom surface towards the freight car body.

[0010] Vertical frames are fixedly provided on both sides corresponding to the running direction of the multi-row carrier vehicle between the carrier vehicle lifting platform and the freight car body. Horizontal guide rails are provided on the vertical frames along the running direction of the multi-row carrier vehicle. Guide connection structures that are slidably connected to the horizontal guide rails are respectively provided on both sides of the multi-row carrier vehicle corresponding to the two horizontal guide rails.

[0011] It further includes an anti-tipping protection device for protecting the barrels stacked in the car body from tipping over.

[0012] The anti-tipping protection device includes horizontal sliding tracks fixedly erected on both sides above the freight car body, a cross beam whose two ends are respectively connected to the horizontal sliding tracks through sliding driving mechanisms and slide on the horizontal sliding tracks, and a guard plate connected to the cross beam through a lifting driving mechanism. The guard plate is in the shape of a long strip plate and can block the outer side walls of the barrels stacked in the car body when descending; alternatively, mounting frames are erected on the upper end or both sides of the multi-row carrier vehicle facing the car body through telescopic driving mechanisms. A guard plate that can be lifted and lowered through a lifting driving mechanism is provided on the mounting frames. The guard plate is in the shape of a long strip plate and can block the outer side walls of the barrels stacked in the car body when descending.

[0013] The loading method of the above-mentioned food phosphoric acid barrel loading system includes the following method steps:

[0014] 1). The freight car body is stably parked in the set parking area;

[0015] 2). The multi-row carrier vehicle is stably parked in place on the carrier vehicle lifting platform. The carrier vehicle lifting platform is raised or lowered so that one of the barrel placement layers of the multi-row carrier vehicle corresponds to the side of the single-row lifting platform;

[0016] 3). The barrels are conveyed one by one to the single-row input line through the sorting conveyor line and are neatly arranged in a single row on the single-row input line according to the set limit of the number of barrels;

[0017] 4). The single-row lifting platform rises to the corresponding height of the single-row input line. The turning plate on the single-row input line is turned into a connecting and transitioning plate and its edge is placed on the single-row lifting platform. Then the single-row transposition and pushing mechanism pushes the barrels neatly arranged on the single-row input line onto the single-row lifting platform and arranges them neatly in place. Then the turning plate on the single-row input line turns back to its original position, repeats step 3) to arrange and wait for the next push, and the single-row lifting platform descends and resets;

[0018] 5) The turning plate on the single-row lifting platform is turned into a connection transition plate and its edge is placed on the corresponding layer for placing barrels, and then the barrels neatly arranged on the single-row lifting platform are pushed out to the corresponding layer for placing barrels through the single-row vehicle-loading pushing mechanism. Then, the turning plate of the single-row lifting platform is turned back to its original position, and step 3) is repeated for arranging and waiting for the next push.

[0019] 6) The lifting platform of the carrier vehicle is raised or lowered to adjust so that another layer for placing barrels corresponds to the side of the single-row lifting platform. Steps 4) and 5) are repeated until the set number of load-bearing layers is completed on the multi-row carrier vehicle. After completion, the lifting platform of the carrier vehicle is at a height where it can move towards the freight car body. The multi-row carrier vehicle moves into the freight car body and stably stops at the corresponding parking position.

[0020] 7) The lifting, pushing, and stacking mechanism of the multi-row carrier vehicle descends to the layer for placing barrels corresponding to the bottommost layer, and then the barrels on each layer for placing barrels are successively pushed out and stacked in the car body from bottom to top. The pushing and stacking process for each layer is as follows: The lifting, pushing, and stacking mechanism corresponds to the layer for placing barrels of the corresponding layer. The turning plate on the layer for placing barrels of the corresponding layer is turned into a connection transition plate and its edge is placed on the inner bottom surface of the car body or the upper surface of the next row of barrels. Then, the lifting, pushing, and stacking mechanism pushes the barrels on the corresponding layer to the stacking position on the inner bottom surface of the car body or stably stacks them on the next row of barrels. Next, the multi-row carrier vehicle retreats a certain distance. At the same time, the lifting, pushing, and stacking mechanism extends a certain distance accordingly to protect the stability of the just-stacked row of barrels. At this time, the turning plate placed on the inner bottom surface of the car body or the next row of barrels is pulled out and reset. The lifting, pushing, and stacking mechanism retracts and resets, and then rises and adjusts to the layer for placing barrels corresponding to the upper layer. The multi-row carrier vehicle advances a certain distance corresponding to the distance that the turning plate is pulled out and the vehicle retreats. In this way, the barrels on each layer for placing barrels are successively pushed out from bottom to top to complete the multi-layer stacking on one side in the car body. The lifting, pushing, and stacking mechanism moves back to the upper end of the multi-row carrier vehicle, and then the multi-row carrier vehicle moves back to the lifting platform of the carrier vehicle.

[0021] 8) Steps 2)-7) are repeated to complete the stacking quantity in the freight car body.

[0022] After the multi-layer stacking on one side in the car body is completed in step 7) above, step 7.1) is carried out. 7.1) The anti-tipping protection device corresponds to above the barrels on the just-stacked side, and then the guard plate is extended downward to block the outer side wall of the barrels on the just-stacked side. When the top row of barrels in the next row of barrels to be stacked is stacked and protected stably, the guard plate retracts upward and resets. In step 8), the anti-tipping protection device repeats step 7.1).

[0023] Alternatively, after the stacking of the upper fabric barrels in the carriage is completed, after step 6), step 6.1) is carried out first and then step 7). In step 6.1), the multi-row carrier vehicle extends the mounting frame so that its guard plate corresponds above the barrels that have been stacked on the upper side. Then, the guard plate is extended downward to block the outer sidewall of the uppermost row of barrels or the outer sidewalls of the uppermost two rows of barrels of the fabric barrels that have just been stacked. In step 7), the multi-row carrier vehicle retreats a certain distance to extract the turning plate and at the same time advances a certain distance while the mounting frame synchronously expands and contracts the same distance.

[0024] By adopting the above technical solutions, a food phosphoric acid barrel loading system and its loading method of the present invention have the following beneficial effects:

[0025] 1. The mechanical structure of the system of the present invention can be compactly arranged, with a reasonable structural space layout, which can reduce the occupied space, and the working method of the system is reasonable and orderly.

[0026] 2. The production and manufacturing of the mechanical device are easy to achieve, and its mechanical structure is relatively stable and not prone to failure.

[0027] 3. The entire system does not require high-precision positioning requirements in each step, so it is not easy to have other situations that affect the normal operation, and it is also beneficial to improve the efficiency of each step process.

[0028] 4. The multi-row carrier vehicle can carry, push multiple rows at the same time, and enter the carriage to stack them in sequence. Stacking multiple rows into one side in this way is different from the existing stacking method of barrels row by row from the inside out and layer by layer from the bottom up. It is directly stacked from the inside out side by side, and there will be no narrow stacking space that is inconvenient for stacking activities. The carriage space can be more utilized for stacking, increasing the stacking quantity, and it is beneficial to improve the loading and transportation efficiency and reduce the energy consumption of transportation.

[0029] 5. It can realize the mechanical full-automatic stacking of barrels, without the need for manual participation, reducing labor costs and improving economic benefits.

[0030] 6. The mechanical structure settings of the above devices can achieve better mechanical stacking stability, and can better avoid the situation of tipping during the stacking process.

[0031] 7. The above system structure settings and working methods can be adapted to various loading applications, such as the loading of containers, the loading of freight cars without a top surface, and the loading of flatbed freight cars. The above system structure can also be applied to the loading of other packages and other specifications of goods, such as the loading of boxed items, and can easily handle the loading task.

[0043] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0044] This embodiment discloses a food phosphoric acid barrel loading system, such as Figures 1 - 5As shown, it is usually fixedly installed and arranged in a set loading area during normal application, and there is a stable docking position for the freight vehicle carriage. As shown in the figure, it is a platform-type loading area layout structure, which is mainly set according to the loading carriage, loading environment, etc. The system structure includes an arranged conveyor line (not shown in the figure) for conveying the drum 1, a multi-row carrier vehicle 2 that can carry multiple rows of drums 1 at the same time, a single-row shaping and pushing device 3 for conveying the drums 1 in quantity and arranging them into a single row and pushing them onto the multi-row carrier vehicle 2, a carrier vehicle lifting platform 4 for carrying and lifting the multi-row carrier vehicle 2, and an anti-tipping protection device 6 for protecting against tipping after the drums 1 are stacked in the carriage 20. The start of the drum loading is the arranged conveyor line. Through arranging on the single-row shaping and pushing device 3 to reach the neat arrangement of the set single-row stacking quantity, through the transposition and transition of the single-row shaping and pushing device 3, and then to the multi-row carrier vehicle 2 for multi-row transportation into the carriage 20 for multi-row stacked and surface stacking work. The system is controlled by a loading control system, which includes hardware device components and system software programs. These can refer to the existing control system technologies and are easily obtained by those skilled in the art, so they will not be described in detail here, which does not affect the clear understanding of the technical solution of this case. The following will describe in detail the specific structural position connection relationship of each part of the device in the embodiment of the present invention with reference to the drawings.

[0045] Regarding the arranged conveyor line, which is not shown in the figure in this embodiment, existing mature conveyor line technologies can be adopted. There are conveyor lines in many fields, and those skilled in the art can easily obtain the relevant technical structures, so the structural settings will not be described in detail here, which does not affect the clear understanding of the corresponding technical solution. For the conveyor front end of the conveyor line applied in this embodiment, there can be a device for automatically grasping and clamping the drum onto the conveyor line. In addition, the conveyor line can be provided with a sensing counting device that can perform counting during the conveying process, which is convenient for controlling the quantity of each row according to the stacking arrangement requirements. It can also be segmented, and there is a movable separation mechanism between each segment, so that the quantity of each row can be counted and separated in advance, which is convenient for quickly conveying each row later and is beneficial to improving the efficiency of subsequent conveying transposition and pushing onto the multi-row carrier vehicle.

[0046] The single-row shaping and pushing device 3, as Figures 1 - 4As shown in the figure, it includes a single-row input line 31, a single-row position change and ejection mechanism 32, a single-row lifting platform 33 and a single-row vehicle loading and ejection mechanism 34. One end of the single-row input line 31 is provided with an in-place blocking component 311, and the other end is the output end of the input end connected to the arrangement conveying line. The barrels entering the single-row input line 31 can be positioned according to the number of each row required by the setting. When the number is reached, the subsequent input is stopped. The input can be further conveyed here to reach the limit positioning and be arranged neatly. The in-place blocking component 311 here can be an adjustable position setting, which can be adjusted according to different limit requirements. There is also a mechanism for pushing and positioning that can be further set to push the barrels, so that the barrels can be closely arranged without gaps, which is conducive to subsequent loading and stacking.

[0047] The single-row lifting platform 33, as Figures 1 - 4 As shown in the figure, it is arranged on one side of the single-row input line 31, and its structural arrangement can keep the limit positions neatly arranged after the transposition. It is mainly used for transposition and provides the conveying arrangement of the next row, which is beneficial to the subsequent steps and saves time and improves efficiency. Therefore, it is a platform that can be raised and lowered, and adopts scissor lift or driving cylinder to push the jacking and resetting. When it rises, it can push the material barrel into the corresponding single-row input line 31, and when it descends, it can be staggered to facilitate the execution of another action, and adjacent devices will not interfere with each other's actions.

[0048] The single-row displacement ejection mechanism 32 is as follows: Figures 1 - 4 As shown in the figure, the other side of the single-row input line 31 opposite to the single-row lifting platform 33 is arranged for pushing the single-row material barrels 1 with the upper limit arranged neatly on the single-row input line 31 onto the single-row lifting platform 33. Its structure can be composed of a pushing cylinder, a pushing guide structure and a pushing plate combination. The pushing plate is driven by the pushing cylinder to stably push out and retract under the limitation of the pushing guide structure. The two ends of the pushing plate can be respectively provided with end limiting plates extending in the pushing direction for limiting the material barrels at both ends, so as to maintain the pushing position during the displacement movement. Here, the two end limiting plates can be set to an adjustable position structure, and the position can be adjusted as needed to adapt to different numbers of limited adjustments.

[0049] The single-row boarding and pushing-out mechanism 34 is as follows: Figures 1 - 4 As shown in the figure, it is arranged below the single-row input line 31 and corresponding to one side of the single-row lifting platform 33, and is used to push the single-row barrels on the single-row lifting platform 33 onto the multi-row carrier 2. Its structural arrangement can be the same as the above-mentioned single-row transposition and pushing mechanism 32, and its functional effect is the same.

[0050] In this embodiment, some heavy items are taken into consideration, such as the bucket items in this embodiment, which usually weigh about 30 kg. In order to achieve a smooth transition of the transposition movement, the single-row input line 31 and the single-row lifting platform 33 are hingedly provided with a flip plate 35 on one side of the push-out side.Figures 1 - 5 As shown, a flipping drive mechanism is provided between the flipping plate 35 and the single-row input line 31 or the single-row lifting platform 33 to control the flipping action. When flipped to the vertical position, it serves as a limit blocking plate for the entry of the single-row input line 31 and the single-row lifting platform 33 to play a limiting role. When the flipping plate 35 is flipped to the horizontal state, it serves as a connecting and transitional plate for the pushing out of the material bucket 1. The hinged opposite side of the connecting and transitional plate is the connecting and placing flat plate edge 351. This edge is set with a thinner structure and can ensure smooth and stable entry into the next position when placed on the next position. After the material is pushed out and crosses the connecting and placing flat plate edge 351, the flipping plate 35 can be flipped back to its original position. The structure is simple and can effectively achieve the functional effect. For some lighter or relatively flat items, such as items packed in cartons, if there are no problems during the pushing process, the structure of the connecting and transitional plate may not be required, and even the flipping plate 35 may not be set. Specifically, it can be selected according to the items to be transported and loaded, or can be adapted to various usage settings.

[0051] The lifting platform 4 of the carrier vehicle is arranged on the other side of the single-row lifting platform 33 opposite to the single-row pushing-out mechanism 34 for the vehicle to get on. Its upper surface is the working surface for carrying multiple rows of carrier vehicles 2. The working surface can be provided with structures such as docking and positioning structures, docking and connecting structures, or lifting height sensing and positioning structures for multiple rows of carrier vehicles 2 to improve stability. Since the multiple rows of carrier vehicles 2 are multi-layered and have a relatively high height, in the actual environment, a pit can be dug on the ground in the corresponding area, and the lifting platform 4 of the carrier vehicle can be embedded and installed therein. The structure is reasonably arranged and does not need to increase the overall height of the system. It has a large load-bearing capacity, and a more powerful lifting structure, such as a hydraulic scissor lift, can be used for lifting.

[0052] The multiple rows of carrier vehicles 2, such as Figures 1 - 5As shown in the figure, it works by running back and forth between the carrier lift 33 and the freight car body 20. The multi-row carrier includes a gantry body 21, multiple layers of bucket placement layers 22 arranged at intervals up and down in the gantry body 21, and a lifting and pushing stacking mechanism 23 that can be lifted corresponding to each layer of bucket placement layers 22 is provided on the gantry body 21 on the side of the bucket placement layer 22 facing the single-row lifting platform 33. Of course, the carrier also has a driving and walking mechanism for moving. This structure can adopt the driving and walking mechanism of the existing carrier. In this embodiment, it is preferably one that can achieve a large load and can move smoothly. The specific form is not limited and will not be described in detail in this embodiment, which does not affect the clear understanding of this case. The lifting and pushing stacking mechanism 23 is used to push the whole row of buckets on the bucket placement layer 22 to the corresponding position in the car body 20 for stacking. In this embodiment, a turning plate 35 with the same function is hinged on the pushing side edge of the bucket placement layer 22. A turning drive mechanism is provided between the turning plate 35 and the bucket placement layer. When turned upward, it serves as an entry limit blocking plate on the pushing side of the bucket placement layer, and when turned downward, it serves as a connection and transition plate for bucket pushing. The hinged opposite side of the connection and transition plate is the connection and placement flat edge, and the structural function is the same. In addition, in order to place items at different heights and adjust the stacking height position on the bucket placement layer 22, the bucket placement layer 22 of the multi-row carrier 2 in this embodiment can be set to be able to adjust the height position. For example, both ends of the bucket placement layer 22 are erected on the side frames of the gantry body 21 through a lifting drive mechanism, and the height of the bucket placement layer 22 can be adjusted by this lifting drive mechanism, so as to adjust according to the height usage requirements. Also, according to the usage requirements, a stable connection mechanism for connecting with the carrier lift 4 or the inner bottom surface of the freight car body 20 can be further provided at the bottom or lower parts on both sides of the multi-row carrier 2 to improve the stability of docking. For example, it includes electromagnetic connection devices arranged on both lower sides of the multi-row carrier 2, which can be adsorbed and connected to the working surface of the carrier lift 4 or the inner bottom surface of the car body 20, which is usually made of a metal material that can be magnetically adsorbed. When installed, the electromagnetic connection device can be connected to the lower part of the multi-row carrier 2 through a lifting drive mechanism. After moving in place, the lifting drive mechanism drives it to descend and contact the connecting surface, and then it is energized to make it magnetic and can be adsorbed on the metal, so as to achieve connection. The adsorption connection structure is simple and convenient. The electromagnetic connection device can include multiple electromagnetic blocks that can be independently adsorbed and connected, and multi-point adsorption can improve the adsorption stability and adsorption force. In addition, the moving position of the multi-row carrier, especially the stacking position in the car body, is different each time. In order to achieve better moving positioning, a sensing and positioning device for running and positioning can be provided on it, which is simple to set and can achieve the required effective positioning.

[0053] In this embodiment, since the moving back-and-forth route of the multi-row carrier vehicle 2 is relatively flat, short-distance, and has a simple route, and the determination of the moving and parking positions is not complicated, but being able to operate more accurately and stably can further improve the stability and reliability of the system operation. Therefore, to further improve the moving stability and direction accuracy, in this embodiment, a guide rail guiding mechanism can be provided between the bottom of the multi-row carrier vehicle 2 and the carrier vehicle lifting platform 4 and between the ground from the carrier vehicle lifting platform 4 to the freight car body 20 to achieve guided movement. For example, Figure 1 As shown in the figure of the ground with guide rails, the guide rail guiding mechanism can be two parallel ones arranged along the back-and-forth advancing direction, which can effectively ensure the accuracy of the moving direction and improve the moving stability. Since the carrier vehicle lifting platform 4 has a lifting action, the parts of the guide rail guiding mechanism on the carrier vehicle lifting platform 4 and the ground are separable and can correspond to the guide rails, and the separation does not affect the lifting. The guide rails on the ground between the carrier vehicle lifting platform 4 and the freight car body 20 can be of a multi-section combination type and can be extended into or retracted from the inner bottom surface of the freight car body 20 at the corresponding height through a telescopic driving mechanism to meet the use of the guide rails inside the carriage. The segmented and telescopic setting can also prevent the guide rails from stretching in and affecting the lifting of the carrier vehicle lifting platform 4 for carrying the multi-row carrier vehicle 2. For the functional effect of improving the stable movement of the multi-row carrier vehicle 2 described above, alternatively, vertical frames can be fixedly provided on both sides corresponding to the running direction of the multi-row carrier vehicle 2 between the carrier vehicle lifting platform 4 and the freight car body 20, and horizontal guide rails arranged along the running direction of the multi-row carrier vehicle 2 are provided on the vertical frames. For example, Figure 2 As shown in the frame structure with horizontal guide rails, the horizontal guide rails are installed on the vertical frames through a telescopic driving mechanism and can be extended into or retracted from the inner side surface of the freight car body. Guide connection structures slidably connected to the horizontal guide rails are respectively provided on both sides of the multi-row carrier vehicle 2 corresponding to the two horizontal guide rails. This additional guiding and sliding connection on both sides can not only ensure the accuracy of the moving direction but also improve the moving stability of the multi-row carrier vehicle 2. Another note is that for the loading application of a flatbed freight car, when the following first anti-tipping protection device 6 is provided, the above horizontal guide rails can be directly extended and erected without telescopic setting. The above two structures can be combined or selected according to factors such as the structure of the freight vehicle carriage, the surrounding environmental space, the mechanical structure, and the load during loading, such as the loading of containers, the loading of freight cars without a top surface, and the loading of flatbed freight cars. There are differences in the spatial openness. Some structures require a larger space for installation, while some cannot be installed and need to be abandoned or other settings need to be selected.

[0054] In practical applications, considering that the stacking of items of different sizes and shapes may be unstable during the stacking process, resulting in tipping over, which causes great trouble, the system of the present invention is further provided with an anti-tipping protection device 6 for protecting the drums 1 stacked in the carriage 20 from tipping over. Since this device is corresponding to the position of the loading carriage, for different vehicle models, the space of the loading carriage is different, and some anti-tipping protection structures may not be universal. For this reason, this embodiment discloses two specific implementation manners with different structures as shown in the figure.

[0055] First, the anti-tipping protection device 6 includes horizontal sliding tracks 61 (arranged along the length direction of the carriage) fixedly installed on both sides above the freight carriage 20 through vertical frames, a cross beam 62 whose two ends are respectively connected to the horizontal sliding tracks 61 through sliding drive mechanisms and slide on the horizontal sliding tracks 61, and a guard plate 63 connected to the cross beam 62 through a lifting drive mechanism. As Figure 2 shown, the guard plate 63 is a long strip-shaped plate, and when it descends, it can block the outer side wall of the drum 1 stacked in the carriage 20. End baffles can be respectively provided at both ends of the guard plate 63 to hold the drums at both ends, which is beneficial to improving the blocking stability of the protection. The guard plate 63 can be a structure that can adjust the distance between the end baffles to adapt to the stable blocking adjustment in different length ranges. Since this structure is set above the carriage 20, this structure is not suitable for the protection of containers and is suitable for flatbed freight vehicles or freight vehicle models without a top panel, and the protection and blocking effect is good.

[0056] Second, the anti-tipping protection device 6 is provided with a mounting frame 61 connected by a telescopic drive mechanism on the upper end or both sides of the multi-row carrier 2 facing the carriage side. As Figure 1 、 Figure 3 and Figure 5 shown, the mounting frame 61 is provided with a guard plate 63 that can be lifted and lowered through a lifting drive mechanism. The guard plate 63 is a long strip-shaped plate, and when it descends, it can block the outer side wall of the drum 1 stacked in the carriage 20. The structural setting of the guard plate 63 can be the same as that of the guard plate structure in the previous type. This structure is directly set on the multi-row carrier and follows it back and forth. The structure can directly enter the carriage and perform blocking protection inside the carriage. When the guard plate 63 is not in use, it is located above to avoid the stacking working space and does not affect the normal work of loading and pushing out the stack. Therefore, it is applicable to container, flatbed freight vehicles or freight vehicle models without a top panel. However, this kind of blocking protection is the blocking protection during the current stacking process, which is different from the previous one. Therefore, for those that may be prone to tipping over after stacking, the previous type can be adopted, and for those that are in a relatively stable state after stacking, the second structure can be considered. The specific actual use can be selected according to the actual situation.

[0057] The loading method of the above-mentioned food phosphoric acid drum loading system includes the following method steps:

[0058] 1), The freight car body is stably parked on the set parking area;

[0059] 2), The multi-row carrier is stably parked in position on the carrier lift platform. By raising or lowering the carrier lift platform, one of the drum placement layers of the multi-row carrier is positioned corresponding to the side of the single-row lift platform;

[0060] 3), The drums are conveyed one by one to the single-row input line through the sorting conveyor line and are neatly arranged in a single row on the single-row input line according to the limit of the set number of drums;

[0061] 4), The single-row lift platform rises to a height corresponding to the single-row input line. The turning plate on the single-row input line turns into a connecting transition plate and its edge is placed on the single-row lift platform. Then, the single-row transposition and pushing mechanism pushes the drums neatly arranged on the single-row input line onto the single-row lift platform for limit and neat arrangement. Then, the turning plate on the single-row input line turns back to its original position, repeats step 3) for arrangement and waits for the next push, and the single-row lift platform descends and resets;

[0062] 5), The turning plate on the single-row lift platform turns into a connecting transition plate and its edge is placed on the corresponding drum placement layer. Then, the single-row loading and pushing mechanism pushes the drums neatly arranged on the single-row lift platform onto the corresponding drum placement layer. Then, the turning plate of the single-row lift platform turns back to its original position, repeats step 3) for arrangement and waits for the next push;

[0063] 6), By raising or lowering the carrier lift platform for adjustment, another drum placement layer is positioned corresponding to the side of the single-row lift platform. Repeat steps 4) and 5) until the set number of load-bearing layers is completed on the multi-row carrier. After completion, the carrier lift platform is at a height where it can move towards the freight car body. The multi-row carrier moves into the freight car body and stably parks at the corresponding parking position;

[0064] 7) The lifting and pushing stacking mechanism of the multi-row carrier vehicle descends to the corresponding lowest layer of the bucket placement layer, and then successively pushes out the buckets on each layer of the bucket placement layer from bottom to top and stacks them in the carriage. The pushing and stacking process for each layer is as follows: The lifting and pushing stacking mechanism corresponds to the bucket placement layer of the corresponding layer. The turning plate on the bucket placement layer of the corresponding layer turns into a connecting transition plate, and its edge is placed on the inner bottom surface of the carriage or the upper surface of the next row of buckets. Then, the lifting and pushing stacking mechanism pushes out the buckets on the corresponding layer to the stacking position on the inner bottom surface of the carriage or stably stacks them on the next row of buckets. Next, the multi-row carrier vehicle retreats a certain distance. At the same time, the lifting and pushing stacking mechanism extends a certain distance accordingly to protect the stability of the just-stacked row of buckets. At this time, the turning plate placed on the inner bottom surface of the carriage or the next row of buckets is pulled out and reset, and the lifting and pushing stacking mechanism retracts and resets, and then rises and adjusts to the corresponding upper layer of the bucket placement layer. The multi-row carrier vehicle advances a certain distance corresponding to the distance that the turning plate is pulled out and retreated; in this way, the buckets on each layer of the bucket placement layer are successively pushed out from bottom to top to complete the multi-layer stacking on one side in the carriage. The lifting and pushing stacking mechanism moves and resets to the upper end of the multi-row carrier vehicle, and then the multi-row carrier vehicle moves back to the carrier vehicle lifting platform; during the period when the multi-row carrier vehicle retreats to the carrier vehicle lifting platform for loading, if it is necessary to insert protective materials such as foam boards at both ends of each layer, it can be carried out during this period, either manually or with the assistance of equipment; in addition, for those with a height lifting and adjusting structure for the bucket placement layer, if it is necessary to adjust the height of the bucket placement layer for the next layer to be stacked, the height lifting and adjusting is carried out before the turning plate turns into the connecting transition plate. For those without a height lifting and adjusting structure for the bucket placement layer, the height of the bucket placement layer has been set before the loading work. During the stacking work, the height of the corresponding layer is slightly higher than the stacking position height, but it does not affect the stacking. Therefore, the height does not need to be adjusted during the stacking work. Specifically, for this point, it can be selected and set according to whether the height difference affects the stacking work of the loaded items. For example, for some relatively square packaging box items, the height difference has little impact;

[0065] 8) Repeat steps 2)-7) to complete the stacking quantity in the freight carriage.

[0066] After the multi-layer stacking on one side in the carriage is completed in step 7) above, step 7.1) is carried out. Step 7.1): The anti-tipping protection device corresponds to above the just-stacked side of buckets, and then extends the guard plate downward to block the outer side wall of the just-stacked side of buckets (preferably on the outer side wall of the top row of buckets or the top two rows of buckets in the top two layers). When the top row of buckets in the next side to be stacked is stacked stably and is protected, the guard plate retracts upward and resets. In step 8), the anti-tipping protection device repeats step 7.1);

[0067] Alternatively, after the upper fabric barrels in the carriage are stacked, after step 6), step 6.1) is carried out first and then step 7). In step 6.1), the multi-row carrier vehicle makes its guard plate correspond above the barrels that have been stacked above by extending the mounting frame, and then extends the guard plate downward to block the outer sidewall of the top row of barrels or the outer sidewalls of the top two rows of barrels of the just-stacked fabric barrels. In step 7), the multi-row carrier vehicle retreats a certain distance to extract the turning plate and at the same time advances a certain distance while the mounting frame synchronously extends and retracts the same distance.

[0068] Here, it should be specifically noted that the barrel 10 of the present invention can be other items or packaged items that need to be loaded onto a freight vehicle, and the "barrel" included in the above product names is not limited to a physical barrel.

[0069] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
