Description

Technical Field

[0001] The present invention relates to the technical field of palletizing devices, and in particular to an in-box palletizing device. Background Art

[0002] The existing palletizing device used in containers can refer to the application number CN201510861386.X. The existing palletizing device includes a frame, a front-end loading mechanism, a conveying mechanism, and a pushing mechanism. During palletizing, the conveying mechanism conveys the items to the front-end loading mechanism, and the front-end loading mechanism drives the items laterally so that the items are arranged laterally on the front-end loading mechanism. When the front-end loading mechanism is full of items, the pushing mechanism pushes the items on the front-end loading mechanism out. After the pushing mechanism resets, the conveying mechanism again outputs the items to the front-end loading mechanism, and the palletizing of the items is completed in a reciprocating cycle. During palletizing, in order to ensure the stability of the stacking of items, the pushing mechanism pushes at a slow speed, which in turn causes the pushing mechanism to reset at a slow speed. Therefore, when the existing palletizing device outputs items from the front-end loading mechanism, the conveying mechanism needs to wait for the pushing mechanism to reset and stop outputting items, thereby reducing the palletizing efficiency. Summary of the Invention

[0003] In order to solve the problem that the existing in-box palletizing device needs to stop outputting items when outputting items on the front-end loading mechanism, thereby reducing the palletizing efficiency, the present invention proposes an in-box palletizing device, which does not require the conveying mechanism to stop outputting items when outputting items on the front-end loading mechanism, and has high palletizing efficiency.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A palletizing device in a box includes a frame, a front-end loading mechanism for supporting and arranging articles laterally, a conveying mechanism for conveying articles to the front-end loading mechanism, and a first pushing mechanism for outputting articles on the front-end loading mechanism. A transverse arranging mechanism capable of driving articles laterally to arrange a plurality of articles laterally is provided between the front-end loading mechanism and the conveying mechanism. A second pushing mechanism for pushing articles arranged on the transverse arranging mechanism onto the front-end loading mechanism is provided on the side of the transverse arranging mechanism away from the front-end loading mechanism.

[0006] With the above arrangement, the items output by the conveying mechanism first arrive at the transverse arrangement mechanism, which then arranges the items transversely. The second pushing mechanism pushes the items arranged by the transverse arrangement mechanism to the front loading mechanism and then immediately resets. When the first pushing mechanism pushes the items on the front loading mechanism, the conveying mechanism does not need to wait for the first pushing mechanism to reset and can continue to output items to the transverse arrangement mechanism. The transverse arrangement mechanism continues to arrange the items transversely. While the transverse arrangement mechanism is arranging the items, the first pushing mechanism completes its reset, and the second pushing mechanism can again push the items on the transverse arrangement mechanism to the front loading mechanism. This cycle repeats to complete palletizing. During the palletizing process, the conveying mechanism does not need to stop to wait for the first pushing mechanism to reset, thereby improving palletizing efficiency.

[0007] Furthermore, the transverse arrangement mechanism includes a first bracket, a plurality of first Mecanum wheels rotatably connected to the first bracket and used to support the objects, and a first driving mechanism for driving the first Mecanum wheels to rotate so as to move the objects transversely.

[0008] With the above arrangement, the first drive mechanism controls the rotation of the first Mecanum wheel, so that the objects on the first Mecanum wheel can move in different directions, so that the objects can stably enter the transverse arrangement mechanism and then be arranged transversely.

[0009] Furthermore, the first pushing mechanism is arranged on the front-end carrying mechanism, the frame is fixedly connected to the gantry, the gantry is fixedly connected to a guide rail extending vertically, the guide rail is slidably connected to a slider, the slider is fixedly connected to the front-end carrying mechanism through a connecting arm, the upper end of the gantry is rotatably connected to the upper sprocket, the lower end of the gantry is rotatably connected to the lower sprocket, the upper sprocket and the lower sprocket are connected by a chain transmission, the connecting arm is connected to the chain, and the lower end of the gantry is provided with a first motor for driving the lower sprocket to rotate so that the front-end carrying mechanism and the first pushing mechanism move vertically.

[0010] Through the above arrangement, the front-end loading mechanism and the first pushing mechanism can be driven to move up and down, so as to stack the articles to different heights.

[0011] Furthermore, the front-end loading mechanism includes a second bracket fixedly connected to the connecting arm, a plurality of rotating rollers arranged in sequence along the transverse direction and rotatably connected to the second bracket, and a second driving mechanism for driving the rotating rollers to rotate so as to move the articles transversely. The second driving mechanism is arranged in the rotating rollers or on the second bracket. The first pushing mechanism includes a first push plate and a first transmission belt arranged between the rotating rollers and used to drive the first push plate to move longitudinally. The upper side of the first push plate is higher than the rotating roller, and when the article moves to the transverse arrangement mechanism, the bottom surface of the article is higher than the upper side of the first push plate.

[0012] With this arrangement, when the second pushing mechanism pushes items on the transverse arrangement mechanism, the items on the transverse arrangement mechanism can pass over the upper side of the first pushing plate and move to the upper side of the rotating roller. When the first transmission belt drives the first pushing plate to move, the first pushing plate can push the items on the rotating roller off the rotating roller, completing a palletizing operation.

[0013] Furthermore, a lifting column is provided on the side of the transverse arrangement mechanism away from the front-end loading mechanism, the lifting column and the conveying mechanism are arranged transversely, the lifting column is slidably connected to the lifting frame, the lifting frame is threadedly connected to a screw rod rotatably connected to the lifting column, the lifting column is provided with a second motor for driving the screw rod to rotate to drive the lifting frame to move vertically, the second pushing mechanism includes a second push plate provided on the side of the lifting frame close to the transverse arrangement mechanism, and a third driving mechanism provided on the lifting frame and used to drive the second push plate to move longitudinally, and one end of the second push plate extends above the end of the conveying mechanism close to the transverse arrangement mechanism.

[0014] The above arrangement enables the second push plate to be raised and lowered. Before pushing an item, the second push plate is raised to avoid interference between the items being delivered by the conveyor mechanism and the second push plate. After the items are pushed to the front loading mechanism, the third drive mechanism and the second push plate are raised to more quickly make room for the items to be arranged above the transverse arrangement mechanism, allowing the items to continue to be arranged on the transverse arrangement mechanism after being delivered by the conveyor mechanism.

The rotating rollers are divided into several roller groups, each roller group is composed of two or more adjacent rotating rollers, and each roller group is provided with an independent second driving mechanism to drive the corresponding rotating roller to rotate.

[0019] Through the above arrangement, the width of the front loading mechanism and the first push plate can be adjusted to adapt to containers of different widths.

[0040] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0041] See also Figures 1 to 16A palletizing device in a box includes a frame 11, a front-end loading mechanism 12 for supporting and arranging articles horizontally, a conveying mechanism 13 for conveying articles 21 to the front-end loading mechanism 12, and a first pushing mechanism for outputting articles on the front-end loading mechanism 12. A transverse arranging mechanism 14 capable of driving articles horizontally to arrange a plurality of articles horizontally is provided between the front-end loading mechanism 12 and the conveying mechanism 13. A second pushing mechanism for pushing articles arranged on the transverse arranging mechanism 14 onto the front-end loading mechanism 12 is provided on the side of the transverse arranging mechanism 14 away from the front-end loading mechanism 12.

[0042] Through the above arrangement, the items output by the conveying mechanism 13 first arrive at the transverse arrangement mechanism 14, which arranges the items transversely. The second pushing mechanism pushes the items arranged by the transverse arrangement mechanism 14 to the front loading mechanism 12 and then immediately resets. When the first pushing mechanism pushes the items on the front loading mechanism 12, the conveying mechanism 13 does not need to wait for the first pushing mechanism to reset and can continue to output items to the transverse arrangement mechanism 14. The transverse arrangement mechanism 14 continues to arrange the items transversely. While the transverse arrangement mechanism 14 is arranging the items, the first pushing mechanism completes its reset, and the second pushing mechanism can once again push the items on the transverse arrangement mechanism 14 to the front loading mechanism 12. This cycle repeats to complete palletizing. During the palletizing process, the conveying mechanism 13 does not need to stop to wait for the first pushing mechanism to reset, thereby improving palletizing efficiency.

[0043] Specifically, as the conveying mechanism 13 delivers items one by one to the transverse arrangement mechanism 14, each time the transverse arrangement mechanism 14 receives an item, it drives the items in a transverse motion to arrange them together transversely. After the transverse arrangement mechanism 14 has arranged a certain number of items, the second pushing mechanism pushes the items arranged on the transverse arrangement mechanism 14 onto the front loading mechanism 12 and immediately resets, allowing the conveying mechanism 13 to continuously output items to the transverse arrangement mechanism 14. After the second pushing mechanism resets, the transverse arrangement mechanism 14 continues to receive and arrange items transversely. While the transverse arrangement mechanism 14 is arranging items, the first pushing mechanism slowly pushes the items on the front loading mechanism 12 out and resets them. After the first pushing mechanism resets, the second pushing mechanism can continue to push items toward the front loading mechanism 12.

[0044] Among them, since the friction force on the bottom surface of the items is relatively large when the items move from the horizontal arrangement mechanism 14 to the front loading mechanism 12, the second pushing mechanism runs faster, and the time spent by the second pushing mechanism from the start of pushing to the completion of resetting is very short, so that the operation of the second pushing mechanism does not affect the output of the conveying mechanism 13.

[0045] As an implementation, the lateral arrangement mechanism 14 includes a first bracket 141, a plurality of first Mecanum wheels 142 rotatably connected to the first bracket 141 and used to support objects, and a first drive mechanism (not shown in the figure) for driving the first Mecanum wheels 142 to rotate to move the objects laterally.

[0046] With the above arrangement, the first drive mechanism controls the rotation of the first Mecanum wheel 142 so that the objects on the first Mecanum wheel 142 can move in different directions, thereby enabling the objects to stably enter the transverse arrangement mechanism 14 and then be arranged transversely.

[0047] Specifically, when the conveying mechanism 13 conveys the article to one end of the transverse arrangement mechanism 14, the first Mecanum wheel 142 supports the article, and the first driving mechanism drives the first Mecanum wheel 142 to rotate, so that the article continues to move forward in the longitudinal direction until the entire article is located on the transverse arrangement mechanism 14. Figure 6 Then, the first Mecanum wheel 142 drives the object to move laterally, so that the object moves to the other end of the transverse arrangement mechanism 14. Similarly, each time the conveying mechanism 13 inputs an object, the first Mecanum wheel 142 drives the object laterally, so that the objects are arranged laterally in sequence at the end of the transverse arrangement mechanism 14 away from the conveying mechanism 13. Figure 7 In this embodiment, the transverse arrangement mechanism further includes a plurality of drive shafts 143 rotatably connected to the first bracket 141 and extending longitudinally, see Figure 2 The first Mecanum wheel 142 is mounted on the drive shaft 143. The first drive mechanism can be configured as a motor that is transmission-connected to the drive shaft 143. When the conveying mechanism 13 conveys the article to the transverse arrangement mechanism 14, the drive shaft 143 on one side of the conveying mechanism 13 rotates to cause the article to move longitudinally and enter the transverse arrangement mechanism 14 as a whole. Then, all the drive shafts 143 rotate synchronously to drive the article to move transversely to the other end of the transverse arrangement mechanism 14 for arrangement.

[0048] As an implementation method, the first pushing mechanism is arranged on the front-end carrying mechanism 12, the frame 11 is fixedly connected to the gantry 111, and the gantry 111 is fixedly connected to a guide rail 112 extending vertically, the guide rail 112 is slidably connected to a slider 113, and the slider 113 is fixedly connected to the front-end carrying mechanism 12 through a connecting arm 114, the upper end of the gantry 111 is rotatably connected to the upper sprocket 115, and the lower end of the gantry 111 is rotatably connected to the lower sprocket 116, the upper sprocket 115 and the lower sprocket 116 are connected by a chain 117, the connecting arm 114 is connected to the chain 117, and the lower end of the gantry 111 is provided with a first motor 118 for driving the lower sprocket 116 to rotate so that the front-end carrying mechanism 12 and the first pushing mechanism move vertically.

[0049] Through the above arrangement, the front loading mechanism 12 and the first pushing mechanism can be driven to move up and down, so as to stack the articles to different heights.

[0050] For details, see Figure 16 When the first motor 118 drives the lower sprocket 116 to rotate, the chain 117 rotates. When the connecting arm 114 is connected to one side of the chain 117, the chain 117 drives the connecting arm 114, the front loading mechanism 12, and the first pushing mechanism to move upward or downward. When the front loading mechanism 12 of the present application unloads items, the front loading mechanism 12 can move upward or downward, thereby stacking the items at different heights.

[0051] As an implementation method, the front-end loading mechanism 12 includes a second bracket 121 fixedly connected to the connecting arm 114, a plurality of rotating rollers 122 arranged in sequence along the horizontal direction and rotatably connected to the second bracket 121, and a second driving mechanism for driving the rotating rollers 122 to rotate so that the article moves laterally. The second driving mechanism is arranged in the rotating rollers or on the second bracket. The first pushing mechanism includes a first push plate 124 and a first transmission belt 125 arranged between the rotating rollers 122 and used to drive the first push plate 124 to move longitudinally. The upper side of the first push plate 124 is higher than the rotating roller 122, and when the article moves to the horizontal arrangement mechanism 14, the bottom surface of the article is higher than the upper side of the first push plate 124.

[0052] With the above arrangement, when the second pushing mechanism pushes the articles on the transverse arrangement mechanism 14, the articles on the transverse arrangement mechanism 14 can pass over the upper side of the first pushing plate 124 and move to the upper side of the rotating roller 122. When the first transmission belt 125 drives the first pushing plate 124 to move, the first pushing plate 124 can push the articles on the rotating roller 122 off the rotating roller 122, completing a palletizing operation.

[0053] For details, see Figure 8 Initially, the first push plate is located above the side of the second bracket close to the transverse arrangement mechanism. After the transverse arrangement mechanism 14 arranges the items, the second push mechanism pushes the items longitudinally and then resets. The items pass the upper side of the first push plate 124 and move to the rotating roller 122. Figure 9 The second driving mechanism drives the rotating roller 122 to rotate, causing the items to move laterally for a certain distance to provide space for subsequent items. This cycle is repeated many times, and the items on the front-end loading mechanism 12 gradually increase. Then the first transmission belt 125 drives the first push plate 124 to move. The first push plate moves to the other side of the second bracket and pushes the items on the rotating roller 122 out. After the items are pushed out, the second pushing mechanism drives the first push plate to reset.

[0054] As an implementation method, a lifting column 144 is provided on the side of the transverse arrangement mechanism 14 away from the front-end loading mechanism 12. The lifting column 144 and the conveying mechanism 13 are arranged transversely. The lifting column 144 is slidably connected to a lifting frame 145. The lifting frame 145 is threadedly connected to a screw rod 146 rotatably connected to the lifting column 144. The lifting column 144 is provided with a second motor 147 for driving the screw rod 146 to rotate to drive the lifting frame 145 to move vertically. The second pushing mechanism includes a second push plate 15 provided on the side of the lifting frame 145 close to the transverse arrangement mechanism 14, and a third driving mechanism provided on the lifting frame 145 and used to drive the second push plate 15 to move longitudinally. One end of the second push plate 15 extends to above the end of the conveying mechanism 13 close to the transverse arrangement mechanism 14.

[0055] The above arrangement enables the second push plate 15 to be raised and lowered. Before pushing an item, the second push plate 15 is raised to avoid interference between the items output by the conveying mechanism 13 and the second push plate 15. After the items are pushed to the front loading mechanism 12, the third driving mechanism and the second push plate 15 are raised to more quickly make room for the items to be arranged above the transverse arrangement mechanism 14, so that the items can continue to be arranged on the transverse arrangement mechanism 14 after being output by the conveying mechanism 13.

[0056] Specifically, when the conveying mechanism 13 conveys articles to the transverse arrangement mechanism 14, the lifting frame 145 is located at the upper end of the lifting column 144, thereby lifting the second push plate 15, and the articles pass under the second push plate 15 and enter the transverse arrangement mechanism 14. When the transverse arrangement mechanism 14 has arranged a certain number of articles, the second motor 147 drives the screw rod 146 to rotate. After the screw rod 146 and the lifting frame 145 rotate relative to each other, the lifting frame 145 drives the third driving mechanism and the second push plate 15 to move downward, and then the third driving mechanism drives the second push plate 15 to move. The second push plate 15 quickly pushes the articles on the transverse arrangement mechanism 14 to the front loading mechanism 12 in the longitudinal direction, and then the second motor 147 drives the screw rod 146 to rotate, and the lifting frame 145 drives the third driving mechanism and the second push plate 15 to move upward. After the third driving mechanism and the second push plate 15 are raised, they can make room for article arrangement above the transverse arrangement mechanism 14 more quickly, so that the conveying mechanism 13 can continue to be arranged on the transverse arrangement mechanism 14 after outputting the articles. Then the third driving mechanism drives the second push plate 15 to move back to the initial position to prepare for the next push.

[0057] As an implementation method, the third driving mechanism includes a third motor 151 arranged on the lifting frame 145, a driving gear 152 connected to the third motor 151, a rack 153 meshing with the driving gear 152 and extending longitudinally, a first driving frame 154 fixedly connected to the rack 153, a second transmission belt 155 arranged on the first driving frame 154 and extending longitudinally, and a second driving frame 156 connected to the second transmission belt 155. The lifting frame 145 is slidably connected to the first driving frame 154, the second driving frame 156 is slidably connected to the first driving frame 154, and the second push plate 15 is fixedly connected to the side of the second driving frame 156 close to the horizontal arrangement mechanism 14.

[0058] The third motor 151 drives the rack 153, the first drive frame 154, the second drive frame 156, and the second push plate 15 to move longitudinally through the drive gear 152. When the second transmission belt 155 moves, the second drive frame 156 slides relative to the first drive frame 154, further driving the second push plate 15 to move, thereby increasing the movement range of the second push plate 15.

[0059] As an implementation method, the second bracket 121 includes two connecting beams 1211 extending laterally and fixedly connected to the connecting arm 114, the rotating roller 122 is rotatably connected between the connecting beams 1211, and a connecting seat 1212 is provided below the rotating roller 122. The side of the connecting seat 1212 facing away from the conveying mechanism 13 is fixedly connected to a plurality of supporting rods 1213 extending longitudinally, the supporting rods 1213 pass through the connecting beams 1211 and are slidingly connected to the connecting beams 1211, and a reinforcing plate 1214 is provided on the outer side of the connecting beam 1211, and the end of the supporting rod 1213 away from the connecting seat 1212 is fixedly connected to the reinforcing plate 1214, and a third transmission belt 1215 for driving the connecting seat 1212 to move longitudinally is provided between the rotating rollers 122.

[0060] Through the above arrangement, the articles output by the front-end loading mechanism 12 can be stacked on other articles more stably.

[0061] Specifically, when the articles are arranged on the rotating roller 122, the third transmission belt 1215 drives the connecting seat 1212 to move, so that the supporting rod 1213 extends to one side of the second bracket 121, and the first transmission belt 125 drives the first push plate 124 to push the articles on the rotating roller 122 onto the supporting rod 1213. Figure 11 and Figure 12 When other items are stacked on the lower side of the supporting rod 1213, the third transmission belt 1215 drives the connecting seat 1212 in the reverse direction, and the supporting rod 1213 retracts to its initial position. Under the squeezing action of the connecting beam 1211, the items fall from the supporting rod 1213 onto the items below. During this process, the items below are basically only subjected to vertical impact force, thereby ensuring the stability of the items below.

[0062] As an implementation method, the front-end carrying mechanism 12 also includes a transverse expansion mechanism that can be extended or rotated relative to the second bracket 121. The transverse expansion mechanism is arranged at both ends of the second bracket 121. The transverse expansion mechanism is rotated or extended to adjust the width of the front-end carrying mechanism 12. The first push plate 124 includes a first push plate body 1241 and an expansion plate 1242 slidably connected to both ends of the first push plate body 1241. The expansion plate 1242 is slid to adapt the width of the first push plate 124 to the width of the transverse expansion mechanism. The rotating roller 122 is divided into several roller groups, each roller group is composed of two or more adjacent rotating rollers 122, and each roller group is provided with an independent second driving mechanism to drive the corresponding rotating roller 122 to rotate.

[0063] Through the above arrangement, the widths of the front loading mechanism 12 and the first pushing plate 124 can be adjusted to accommodate containers of different widths.

[0064] Specifically, the second driving mechanism can be a motor structure provided in the rotating roller, or a motor structure provided on the second bracket, see Figure 8 After the second push plate 15 pushes the articles on the lateral arrangement mechanism 14 to the upper side of one of the roller groups, the roller group on the lower side of the object and the roller group on the left side rotate under the action of the corresponding second driving mechanism to drive the articles to move to the left until the articles are arranged on the lateral expansion mechanism on the left. Figure 9 When the second push plate 15 continues to push the items on the lateral arrangement mechanism 14 to the upper side of the roller group, the roller group on the lower side of the items and the roller group on the right side will drive the items to move to the right until the items are arranged on the right side of the lateral expansion mechanism, see Figure 10 Then the first push plate 124 pushes the items on the front loading mechanism 12 down.

[0065] As an implementation method, a positioning plate 16 extending longitudinally and used to position items is provided at one end of the lateral arrangement mechanism 14 close to the lifting column 144, and the frame 11 is provided with a first electric cylinder (not shown in the figure) for driving the positioning plate 16 to move laterally.

[0066] With this arrangement, the positioning plate 16 positions the first item when the lateral arrangement mechanism 14 arranges the items. Once the lateral arrangement mechanism 14 has arranged the items, the second push plate 15 can push the items on the lateral arrangement mechanism 14 to the designated position on the front loading mechanism 12. Each time the second push plate 15 pushes an item, the first electric cylinder retracts to prevent interference between the second push plate 15 and the positioning plate 16. Once the second push plate 15 is raised, the first electric cylinder continues to extend, and the positioning plate 16 continues to position the items.

[0067] As an implementation method, a vertically extending oil cylinder 17 is provided on the side of the frame 11 , a fourth driving mechanism 171 is provided at the lower end of the oil cylinder 17 , and the fourth driving mechanism 171 is connected to a second Mecanum wheel 172 .

[0068] Through the above arrangement, the present application can be moved in different directions in the container, thereby facilitating adjustment of the position of the present application in the container and facilitating stacking.

[0069] In one embodiment, see Figure 13 The lateral expansion mechanism includes a rotating shaft 18 rotatably connected to the second bracket 121, a supporting assembly 181 fixedly connected to the rotating shaft 18 and used to support articles, the rotating shaft 18 is fixedly connected to a first toggle rod 182, and the second bracket 121 is provided with a second electric cylinder 183, one end of the second electric cylinder 183 is rotatably connected to the second bracket 121, and the other end of the second electric cylinder 183 is rotatably connected to the first toggle rod 182.

[0070] Through the above arrangement, the width of the front-end carrying mechanism 12 can be adjusted by rotating the lateral expansion mechanism.

[0071] Specifically, when the second electric cylinder 183 is extended or retracted, the second electric cylinder 183 drives the rotating shaft 18 and the support assembly 181 to rotate through the first toggle rod 182. When the support assembly 181 extends horizontally, the width of the front end carrier mechanism 12 is larger, and when the support assembly 181 droops, the width of the front end carrier mechanism 12 is smaller.

[0072] In another embodiment, see Figure 14 and Figure 15 The lateral expansion mechanism includes two support plates 19 arranged between the connecting beams 1211. A scissor-type structure is provided on one side of the support plate 19 close to the other support plate 19. The scissor-type structure includes a plurality of connecting rods 191. The telescopic direction of the scissor-type structure is parallel to the extension direction of the connecting beam 1211. The scissor-type structure also includes an upper connecting key 192 arranged at the upper end of the connecting rod 191 and a lower connecting key 193 arranged at the lower end of the connecting rod 191. The upper connecting key 192 of the scissor-type structure is connected to the upper connecting key 193 of the other scissor-type structure through a support roller 194 for supporting an article. The key 192 is connected for transmission, and the lower connecting key 193 of the scissors-type structure is connected for transmission through the first transmission rod 195 and the lower connecting key 193 of the other scissors-type structure. The upper connecting key 192 closest to the rotating roller 122 is rotatably connected to the support plate 19, and the support plate 19 is provided with a limiting groove 196 extending vertically. The lower connecting key 193 closest to the rotating roller 122 is slidably connected in the limiting groove 196, and the support plate 19 is provided with an adjusting mechanism, which is connected to one of the lower connecting keys 193 to realize the extension and retraction of the scissors-type structure by driving the lower connecting key 193 to move.

[0073] Through the above arrangement, the width of the front-end carrying mechanism 12 can be adjusted by the telescopic scissor-type structure.

[0074] Specifically, when the lower connecting key 193 closest to the rotating roller 122 is slidably connected within the limiting slot 196, the lower connecting key 193 can only move up and down along the limiting slot 196. This ensures that the upper connecting key 192 and the lower connecting key 193 always correspond vertically, ensuring that the extension and retraction direction of the scissor-type structure is parallel to the extension direction of the connecting beam 1211. When the scissor-type structure is retracted, the width of the front-end loading mechanism 12 is reduced, while when the scissor-type structure is extended, the width of the front-end loading mechanism 12 is increased. Because the upper connecting key 192 closest to the rotating roller 122 is rotatably connected to the support plate 19, the height of the support roller 194 remains substantially unchanged during the retraction of the scissor-type structure, facilitating the movement of items from the rotating roller 122 to the upper side of the support roller 194. The two scissor-type structures are connected by a transmission mechanism via the support roller 194 and the first transmission rod 195. When one scissor-type structure retracts or retracts under the action of the adjustment mechanism, the other scissor-type structure also retracts or retracts accordingly. Among them, the adjustment mechanism includes an adjustment motor 197 fixedly connected to the support plate 19, the adjustment motor 197 is connected to a second toggle rod 199, and the second toggle rod 199 is connected to the lower connecting key 193 through a second transmission rod 198. When the adjustment motor 197 drives the second toggle rod 199 to rotate, the second toggle rod 199 drives the lower connecting key 193 to move through the second transmission rod 198 to drive the scissors-type structure to extend and retract.

[0075] As an implementation method, a transition mechanism for supporting items so that the items can move from the transverse arrangement mechanism 14 to the front-end loading mechanism 12 is also provided between the front-end loading mechanism 12 and the transverse arrangement mechanism 14. The transition mechanism includes a third bracket 126 and several rollers 127 rotatably connected to the third bracket 126.

[0076] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.
