Technical Field

[0001] The invention relates to an automated loading system and an automated loading method for a large freight vehicle. Background Art

[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 multi-layer loading system of the food phosphoric acid barrels.

[0005] To achieve the above object, the technical solution of the present invention is: a multi-layer loading system for food phosphoric acid barrels, which is characterized in that it includes an arrangement conveyor 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 the barrels according to quantity into a single row and pushing them onto the multi-row carrier, a carrier docking area for the multi-row carrier to dock at a fixed point for loading, and a boarding area on one side of the carrier docking area; the arrangement conveyor is arranged on one side of the boarding area and is not directly opposite to the carrier docking area; the single-row shaping and pushing device includes a movable bottom frame and 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 arranged on the movable bottom frame. The single-row shaping and pushing device can move to the boarding area to correspond to the multi-row carrier and be connected to the arrangement conveyor, and can move away to avoid the moving space of the multi-row carrier for movement and transportation; one end of the single-row input line is provided with a positioning blocking component, and the other end is an input end for connecting to the output end of the arrangement conveyor; the single-row lifting platform is arranged on one side of the single-row input line facing the boarding area; 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 on the single-row lifting platform facing the single-row input line for pushing the single-row barrel on the single-row lifting platform onto the multi-row carrier. The single-row boarding and pushing mechanism includes a liftable push plate and a driving mechanism arranged at both ends of the corresponding push plate for driving the push plate to perform a pushing action; the multi-row carrier runs back and forth between the carrier docking area and the freight car body for work, and it includes a movable base, a gantry body fixedly arranged on the movable base, multiple horizontal shelves arranged up and down in the gantry body, and a horizontal moving mechanism arranged on the gantry body for driving the horizontal shelves to move respectively. One end of the horizontal shelf facing the freight car body is a barrel placement edge, and the entire row of barrels arranged on the barrel placement edge can be pushed out and stacked by the movement of the upper horizontal shelf.

[0006] The bottommost horizontal shelf of the multi-row carrier is a fixed shelf on the movable base or the gantry body. The horizontal shelves above this fixed shelf are horizontally movable horizontal moving shelves. The topmost horizontal moving shelf does not have a barrel placement edge and is only used for pushing out the entire row of barrels. A horizontal guiding and sliding structure is provided between the two side edges of the horizontal moving shelf and the two vertical frames of the gantry body. A pulley and guide rail structure is provided between the bottom of the horizontal moving shelf and the lower horizontal shelf.

[0007] A turning plate is hinged on the pushing-out side edge of the single-row input line, the single-row lifting platform and the placing edge of the drum. A turning driving mechanism is provided between the turning plate and the single-row input line, the single-row lifting platform or the placing edge of the drum. When turned upwards, it serves as an entry limit blocking plate on the pushing-out side of the single-row input line, the single-row lifting platform or the placing edge of the drum. When the turning plate is turned to a horizontal state, it serves as a connection transition plate for drum pushing. The hinged opposite side edge of the connection transition plate is a connection and placement flat plate edge.

[0008] A sensing and positioning device for running and positioning is provided on the multi-row carrier vehicle.

[0009] A guide rail guiding mechanism is provided between the bottom of the multi-row carrier vehicle and the ground between the carrier vehicle docking area and the freight car compartment. The guide rail of the guide rail guiding mechanism on the ground is installed on the ground through a telescopic driving mechanism and can extend into or retract along the inner bottom surface of the freight car compartment.

[0010] An anti-tipping protection device for protecting the drums stacked in the car compartment from tipping is also included.

[0011] The anti-tipping protection device includes horizontal sliding tracks fixedly erected on both sides above the freight car compartment, cross beams slidably connected to the horizontal sliding tracks at both ends through sliding driving mechanisms respectively, and guard plates connected to the cross beams through lifting driving mechanisms. The guard plates are in the shape of long strips and can block the outer side walls of the drums stacked in the car compartment when lowered.

[0012] The loading method of the above-mentioned multi-layer loading system for food phosphoric acid drums includes the following method steps:

[0013] 1). The freight car compartment is stably docked on the set docking area;

[0014] 2). The multi-row carrier vehicle is stably docked in position in the carrier vehicle docking area. The topmost horizontal layer rack of the multi-row carrier vehicle moves backward to expose the top layer of the drum placing edge, and the drum placing edges of each layer of the multi-row carrier vehicle are aligned vertically.

[0015] 3). The single-row shaping and pushing device moves to the loading area to correspond to the multi-row carrier vehicle and is connected to the arrangement conveyor line.

[0016] 4). The drums are conveyed one by one to the single-row input line through the arrangement conveyor line and are neatly arranged in a single row according to the set limit of the number of drums on the single-row input line.

[0017] 5). The single-row lifting platform is lifted to the height corresponding to the single-row input line. The turning plate on the single-row input line is turned into a connection transition plate and its edge is placed on the single-row lifting platform. Then, the single-row transposition and pushing mechanism pushes the buckets neatly arranged on the single-row input line onto the single-row lifting platform and arranges them neatly in the upper limit position. Then, the turning plate on the single-row input line is turned back to its original position, and step 4) is repeated for arrangement and waiting for the next push.

[0018] 6). The single-row lifting platform is lifted to the horizontal layer where the top bucket placement edge of the multi-row carrier vehicle is located. The turning plate of the corresponding bucket placement edge is turned downward to avoid. The turning plate on the single-row lifting platform is turned into a connection transition plate and its edge is placed on the corresponding bucket placement edge. Then, through the single-row loading and pushing mechanism, the buckets neatly arranged on the single-row lifting platform are pushed onto the corresponding bucket placement edge. Then, the turning plate of the single-row lifting platform is turned back to its original position, and the turning plate of the bucket placement edge is turned back to its original position. Then, the single-row lifting platform repeats step 5) and waits for the next push. After the turning plate of the bucket placement edge is turned back to its original position, the horizontal layer where the whole row of buckets has just been pushed in and the upper horizontal layer on it of the multi-row carrier vehicle move backward synchronously to expose the bucket placement edge of the next layer of the horizontal layer for the next whole row of buckets to be pushed onto the corresponding horizontal layer of the vehicle. In this way, it goes down layer by layer until the set number of load-bearing layers is completed on the multi-row carrier vehicle.

[0019] 7). The single-row shaping and pushing device resets and moves away from the loading area to avoid the moving space of the multi-row carrier vehicle.

[0020] 8). The multi-row carrier vehicle moves into the freight car compartment and stably stops at the corresponding parking position.

[0021] 9). Then, the buckets on the bucket placement edges of each layer of the horizontal layer are pushed out and stacked in the car compartment from bottom to top in turn. The pushing and stacking process for each layer is as follows: The turning plate of the corresponding bucket placement edge to be pushed out is turned into a connection transition plate and its edge is placed on the inner bottom surface of the car compartment or the upper surface of the next row of buckets. Then, the upper layer of the layer where the bucket to be pushed out is located moves or all the upper horizontal layers move synchronously to push out the whole row of buckets on the bucket placement edge of this layer and stack them stably at the stacking position on the inner bottom surface of the car compartment or on the next row of buckets. Then, the multi-row carrier vehicle retreats a certain distance. At the same time, the turning plate placed on the inner bottom surface of the car compartment or the next row of buckets is pulled out and reset. Then, the multi-row carrier vehicle advances a certain distance corresponding to the distance of the pulled-out turning plate retreat. In this way, the buckets on the bucket placement edges of each layer are pushed out from bottom to top in turn to complete the multi-layer stacking on one side in the car compartment. Then, the multi-row carrier vehicle moves back to the carrier vehicle parking area.

[0022] 10). Repeat steps 2) - 9) to complete the stacking quantity in the freight car compartment.

[0023] After the multi-layer stacking on one side inside the carriage is completed in step 9), step 9.1) is carried out. In step 9.1), the anti-tipping protection device is correspondingly above the barrels on the side that has just been stacked. Then, the guard plate extends downward to block the outer side wall of the barrels on the side that has just been stacked. When the top row of barrels in the next row of stacked barrels is stacked and protected and stabilized, the guard plate retracts upward to reset. In step 10), the anti-tipping protection device repeats step 9.1).

[0024] By adopting the above technical solutions, a multi-layer 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 layout of the structural space, 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 failures.

[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 can carry multiple rows at the same time, transport and push multiple rows, and can be stacked in sequence when entering the carriage. 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 side by side from the inside out, and there will be no narrow stacking space that is inconvenient for stacking activities. The carriage space can be used for more stacking, improving 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 uses, 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 complete the loading task.

[0050] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0051] A multi-layer loading system for food phosphoric acid barrels disclosed in this embodiment, as Figures 1 - 7 shown, a multi-layer loading system for food phosphoric acid barrels disclosed in this embodiment is usually fixedly installed and arranged in a set loading area, 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 structure of this system includes an arrangement conveyor line 1 for transporting barrels 10, a multi-row carrier vehicle 2 that can carry multiple rows of barrels 10 at the same time, a single-row shaping and pushing device 3 for transporting and arranging the barrels 10 in a single row according to quantity and pushing them onto the multi-row carrier vehicle 2, a carrier vehicle docking area 4 for the multi-row carrier vehicle 2 to dock at a fixed point for loading, a boarding area 5 on one side of the carrier vehicle docking area 1, and an anti-tipping protection device 6 for protecting against tipping after the barrels 10 are stacked in the carriage 20. The start of barrel loading is the arrangement conveyor line. Through arrangement on the single-row shaping and pushing device 3 to reach the set quantity for neat arrangement in a single row, through the position 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 stacking 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 technology and are easily obtained by those skilled in the art. Here, it will not be described in detail, which does not affect the clear understanding of the technical solution of this case. The specific structural position connection relationship of each part of the device in the embodiment of the present invention will be described in detail below with reference to the drawings.

[0052] For the arrangement conveyor line 1, no detailed drawing is made 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. Here, the structural settings will not be described in detail, which does not affect the clear understanding of the corresponding technical solution. For the conveying front end of the conveyor line applied in this embodiment, a device for automatically grasping and clamping the barrels onto the conveyor line can be provided. In addition, the conveyor line can be provided with a sensing counting device for 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 a movable separation mechanism is provided 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 position transition and pushing onto the multi-row carrier vehicle.

[0053] The arrangement conveyor line 1 is arranged on one side of the boarding area 5 and is not directly opposite to the carrier parking area 4; the single-row shaping and pushing device 3 includes a mobile bottom frame 36 and a single-row input line 31, a single-row transposition and pushing mechanism 32, a single-row lifting platform 33 and a single-row boarding and pushing mechanism 34 arranged on the mobile bottom frame 36. One end of the single-row input line 31 is provided with an in-place blocking component 311, and the other end is the input end connected to the output end of the arrangement conveyor line. The barrels entering the single-row input line 31 can be positioned according to the number of each row required to be set. When the number is reached, the rear input is stopped. The input barrels 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 pushing and positioning mechanism that can be further set to push the barrels, so that the barrels can be closely arranged without gaps, which is conducive to the subsequent loading and stacking. The single-row shaping and pushing device 3 can be moved as a whole to the boarding area 5 to correspond to the multi-row transport vehicles 2 and be connected to the arrangement conveyor line 1, and can be moved to avoid the activity space for the movement and transportation of the multi-row transport vehicles 2. A structural setting for mobile guidance and positioning stable parking can be provided between the boarding area 5 and / or the arrangement conveyor line 1 and the single-row shaping and pushing device 3. Some existing technical structures of mobile guidance, positioning, etc. can be easily obtained by technicians in this field, and the structural setting is not specifically limited here.

[0054] The single-row lifting platform 33, such as Figures 2 - 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.

[0055] The single-row displacement ejection mechanism 32 is as follows: Figures 2 - 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.

[0056] The single-row loading and pushing mechanism 34 is arranged on one side of the single-row lifting platform 33 facing the single-row input line 31, and is used to push the single-row barrels on the single-row lifting platform 33 onto the multi-row carrier vehicle 2. Here, to prevent the single-row loading and pushing mechanism 34 from obstructing the pushing of the single-row input line 31 onto the single-row lifting platform 33, the structure of the single-row loading and pushing mechanism 34 includes a liftable push plate 341 and a drive mechanism 342 arranged corresponding to both ends of the push plate 341 for driving the pushing action of the push plate 341. As Figures 2 - 4 shown, it is arranged at both ends to avoid the action space for pushing the barrels. The two ends of the single-row lifting platform 33 are respectively connected with lifting drive cylinders 343 through the drive mechanism 342. Both ends of the push plate 341 are respectively connected to the corresponding lifting drive cylinders 342 to drive their lifting. When rising, the drive mechanism 342 (in the figure, it is mainly composed of a motor, a lead screw, a slider, etc.) drives the moving position of the lifting drive cylinder 343 at the corresponding pushing working position. The moving position of the lifting drive cylinder 343 drives the push plate 341 to move out or move back to its original position. When descending, the push plate 341 is lower than the action space for pushing the barrels.

[0057] In this embodiment, considering some heavy items, such as the common weight of the barrel items in this embodiment can reach about 30 kilograms, which is relatively heavy. To achieve a smooth transition of transposition movement, a turning plate 35 is hinged on the pushing side edge of the single-row input line 31 and the single-row lifting platform 33. As Figures 2 - 7 shown in the figure, a turning drive mechanism is provided between the turning plate 35 and the single-row input line 31 or the single-row lifting platform 33 to control the turning action. When turned to the vertical position, it serves as a limit stop 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 turning plate 35 is turned to the horizontal state, it serves as a connection and transition plate for the pushing of the barrels 1. The hinged opposite side edge of the connection and transition plate is the connection and placement flat edge 351. This edge is set with a thinner structure, and when placed on the next position, it can ensure a smooth and stable entry into the next position. After the barrel is pushed over the connection and placement flat edge 351, the turning plate 35 can be turned back to its original position. The structure is simple and can effectively achieve the effect. For some lighter items or relatively flat items, such as items packed in cartons, where there are no problems during pushing, the structure of the connection and transition plate may not be required, or even the turning plate 35 may not be set. Specifically, it can be selected according to the items to be transported and loaded, or it can be adapted to various usage settings.

[0058] The multi-row carrier 2 operates back and forth between the carrier docking area 4 and the freight car body. It includes a moving base 21, a gantry frame 22 fixedly arranged on the moving base 21, multiple horizontal shelves 23 arranged vertically within the gantry frame 22, and a horizontal moving mechanism 24 arranged on the gantry frame 22 for driving the horizontal shelves 23 to move respectively; the moving base 21 has a driving and walking mechanism for realizing movement. This structure can adopt the driving and walking mechanism of existing carriers. 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. One end of the horizontal shelf 23 facing the freight car body is a bucket placement edge 231. Through the movement of the upper horizontal shelf 23, the whole row of buckets arranged on the bucket placement edge 231 can be pushed out and stacked. Specifically, as Figure 1 , 4 shown in FIGS. 7, the bottommost horizontal shelf 23 of the multi-row carrier 2 is a fixed shelf on the moving base 21 or the gantry frame 22. The horizontal shelves 23 above this layer are horizontally movable shelves. The topmost horizontally movable shelf does not have a bucket placement edge 231 and is only used to push out the whole row of buckets. A horizontal guiding and sliding structure 25 is provided between the two side edges of the horizontally movable shelf and the two vertical frames of the gantry frame 22. A pulley and rail structure 26 is provided between the bottom of the horizontally movable shelf and the horizontal shelf 23 of the lower layer. Through the above structural settings, each horizontally movable shelf can achieve smooth and stable horizontal movement. In this embodiment, a turning plate 35 with the same function is hinged on the pushing side edge of the bucket placement edge 231 of each layer of the horizontal shelf 23. A turning driving mechanism is provided between the bucket placement layers of the turning plate 35. 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 edge of the connection and transition plate is a connection and placement flat plate edge, and the structural function is the same as above.

[0059] In addition, the moving position of the multi-row carrier 2, especially the stacking position inside the car body, is different each time. To achieve better moving positioning, a sensing and positioning device for operation positioning can be provided on it, which is simple to set up and can achieve the required effective positioning.

[0060] 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 stop position is not complicated, but being able to operate more accurately and stably can improve the stability and reliability of the system operation. Therefore, to further improve the moving stability and direction accuracy, a guide rail guiding mechanism can be provided between the bottom of the multi-row carrier vehicle 2 and the ground between the carrier vehicle docking area 4 and the freight car body. The guide rail of the guide rail guiding mechanism on the ground can be two guide rails arranged in parallel along the back-and-forth advancing direction, which can effectively ensure the accuracy of the moving direction and improve the moving stability. The guide rail can be 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 20 to meet the use of the guide rail guiding inside the car body.

[0061] It also includes an anti-tipping protection device for protecting the barrels in the car body from tipping over after stacking. As disclosed in this embodiment Figure 7 shown in, 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 wall of the barrels stacked in the car body when descending.

[0062] 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 further includes an anti-tipping protection device 6 for protecting the barrels 10 in the car body 20 from tipping over after stacking. Since this device is corresponding to the position of the loading car body, and the space of the loading car body is different for different vehicle types, some anti-tipping protection structures may not be universal. For this, this embodiment discloses a specific implementation manner as shown in the figure.

[0063] First, the anti-tipping protection device 6 includes horizontal sliding tracks 61 (arranged along the length direction of the car body) fixedly erected on both sides above the freight car body 20 through vertical frames, a cross beam 62 whose two ends are respectively connected to the horizontal sliding tracks 61 through sliding driving mechanisms and slide on the horizontal sliding tracks 61, and a guard plate 63 connected to the cross beam 62 through a lifting driving mechanism. As Figure 2 shown, the guard plate 63 is in the shape of a long strip plate and can block the outer side wall of the barrels 10 stacked in the car body 20 when descending. End baffles can be respectively provided at both ends of the guard plate 63 for holding the barrels 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 interval distance between the end baffles to adapt to the stable blocking adjustment within different length ranges. Since this structure is set above the car body 20, this structure is not suitable for the protection of containers and is suitable for flat freight cars or freight car models without top panels, and the protection and blocking effect is good.

[0064] The loading method of the above multi-layer loading system for food phosphoric acid barrels includes the following method steps:

[0065] 1). The freight car body is stably parked in the set parking area;

[0066] 2). The multi-row carrier vehicles are positioned and stably parked in the carrier vehicle parking area. The top horizontal layer rack of the multi-row carrier vehicles moves backward to expose the top layer barrel placement edge. The barrel placement edges of each layer of the multi-row carrier vehicles are aligned vertically;

[0067] 3). The single-row shaping and pushing device moves to the loading area to correspond to the multi-row carrier vehicles and is connected to the arrangement conveyor line;
