Description

Technical Field

[0001] This invention relates to the field of logistics loading and unloading equipment technology, and in particular to an automatic loading device for boxed materials. Background Technology

[0002] The logistics process for materials (goods) generally involves warehousing, loading, transshipment, unloading, warehousing again, and distribution. Loading is a crucial step in this process. Currently, loading is primarily done manually, which has several drawbacks: firstly, the working environment is harsh, such as working in enclosed truck compartments during hot weather, especially when loading and unloading high-dust materials; secondly, the labor intensity is high, as loading and unloading large trucks is physically demanding, and with an aging population, recruitment is difficult; thirdly, maintaining efficiency requires a large workforce, resulting in high labor costs; fourthly, there is a risk of goods tipping over and injuring personnel during manual operations; and fifthly, manual loading and unloading of high-risk materials (such as emulsion explosives) poses personal safety hazards. Therefore, to overcome these drawbacks of manual operations, this paper proposes an automated box-type material loading device.

[0003] Using enclosed wagons as a carrier to transport goods is one of the important modes of transport for materials (goods). There are two types of enclosed wagons: gooseneck wagons and flatbed wagons. Large freight trucks generally use gooseneck wagons, which means that there is usually a loading platform about 250mm high at the bottom of the wagon.

[0004] In addition, due to different vehicle models, there will be different height differences between the cargo box floor and the platform floor. When using large trucks to transport goods, in order to improve the loading rate of the cargo box, the materials (goods) will be stacked in different positions during the manual loading process.

[0005] There are many examples of automatic loading devices in the prior art. For example, Chinese Utility Model Patent CN 215159357 U discloses an automatic loading device, which has the following disadvantages: First, the trolley in the device cannot adapt to the height difference between the platform floor and the car floor while ensuring that the height of the conveying surface does not change. Usually, an additional elevator needs to be set up between the platform and the car to adapt to this. Similarly, it cannot overcome the steps in the gooseneck car and cannot be applied to cars with steps, so its application range is limited. Second, the device cannot change the posture of the material, the degree of automation and intelligence is not high, and the loading rate of the car is low. Third, the fixed long oval circulating lifting conveyor (1) set in the device has a structure of two large arcs, and the straight section for continuous feeding and discharging is short, which makes it impossible to work continuously at the lowest and highest points in the car, resulting in low loading efficiency. Fourth, the material picking and placing mechanism (7) set in the device needs to move back and forth on the transverse moving mechanism (8) to pick up the material, which affects the stacking efficiency.

[0006] Chinese utility model patent CN 209209960 U discloses a toggle-type loading machine and loading system, which has the following drawbacks: First, the tracked trolley of the loading machine cannot adapt to the steps inside the car body while ensuring the conveying surface remains unchanged. Second, the loading machine cannot change the posture of the materials, resulting in low automation and intelligence, and low loading rate of the car body. Third, the toggle mechanism of the loading machine is located directly above the material channel, requiring more space when loading the top layer of materials, further reducing the loading rate of the cargo body.

[0007] For example, Chinese utility model patent CN 215206723 U discloses an automatic palletizer, which has the following disadvantages: First, the tracked walking mechanism (100) used in the palletizer cannot adapt to the steps inside the carriage while ensuring that the conveying surface does not change. Second, the palletizer cannot change the posture of the material, the degree of automation and intelligence is not high, and the loading rate of the carriage is low. Third, the feeder (350) set on the palletizer needs to go back and forth to pick up the material, resulting in low loading efficiency. Summary of the Invention

[0008] This invention provides an automatic loading device for box-type materials to solve the technical problem that automatic loading devices for box-type materials cannot adapt to the steps inside gooseneck carriages and platform steps.

[0009] The technical solution provided by this invention is as follows:

[0011] The walking mechanism is used to drive the mounted material posture adjustment mechanism, the liftable continuous lifting mechanism, and the lifting and stacking mechanism to move.

[0012] The rear end of the material posture adjustment mechanism is connected to the telescopic chain conveyor at the end of the workshop platform, and is used to adjust the posture of the box-shaped materials output by the telescopic chain conveyor.

[0016] This invention provides an automatic loading device for box-type materials, which can adapt to the steps of the platform and the entrance of the car body, as well as the steps inside the gooseneck car body of a gooseneck freight car, thus enhancing the adaptability of the car body.

[0060] Combination Figures 1 to 4 According to an embodiment of the present invention, an automatic loading device for boxed materials includes a traveling mechanism 1, a material posture adjustment mechanism 2 mounted on the traveling mechanism 1, a continuously lifting mechanism 3, a lifting and palletizing mechanism 4, a laser radar spatial recognition component 5, a control component 6, and a human-machine interaction component 7. Figure 1 As shown, the present invention provides an automatic loading device for boxed materials, which is used to transport boxed materials 100 along the material conveying path A into the carriage for stacking.

[0061] In an embodiment of the present invention, the side along the material conveying path A is defined as the front end, and the side along the opposite direction of the material conveying path A is defined as the rear end.

[0062] The traveling mechanism 1 is used to drive the material posture adjustment mechanism 2, the lifting and continuous lifting mechanism 3, and the lifting and unloading stacking mechanism 4 to move inside the carriage.

[0063] The material posture adjustment mechanism 2 is located at the rear end of the walking mechanism 1 and is used to adjust the posture of the box material 100.

[0064] The material posture adjustment mechanism 2 is connected at the rear end to the telescopic chain conveyor 200 at the end of the workshop platform, and is used to adjust the posture of the box-shaped material 100 output by the telescopic chain conveyor 200. The telescopic chain conveyor 200 is used to transport the box-shaped material 100 to the material posture adjustment mechanism 2.

[0065] A continuously lifting mechanism 3, positioned at the front end of the material posture adjustment mechanism 2, is used to continuously lift and convey box-type materials 100 to the lifting, unloading, and stacking mechanism 4. Figure 3 As shown, the boxed material 100 is lifted by the lifting and continuous lifting mechanism 3 along the material flow path B and then transported to the lifting, unloading and stacking mechanism 4.

[0066] The lifting and stacking mechanism 4, located at the front end of the continuously lifting mechanism 3, is used to arrange the box-type materials 100 into rows and stack the arranged rows of box-type materials 100 inside the carriage. Once one row of box-type materials 100 is stacked inside the carriage, the lifting and stacking mechanism 4 rises to begin stacking the next layer of box-type materials, such as... Figure 4 The diagram shows the high-level loading of the lifting and stacking mechanism 100 of the present invention.

[0067] The lidar spatial recognition component 5 is used for radar recognition of the environment inside the vehicle compartment. The control component 6 is used to control the operation of the automatic loading device for boxed materials of the present invention. The human-machine interface component 7 is used by the operator to operate the automatic loading device for boxed materials of the present invention.

[0068] To make the present invention clearer, the workflow of the present invention will first be described, in conjunction with... Figures 1 to 4 The walking mechanism 1, equipped with a material posture adjustment mechanism 2, a liftable continuous lifting mechanism 3, a lifting and stacking mechanism 4, a laser radar spatial recognition component 5, a control component 6, and a human-machine interaction component 7, moves into the cargo compartment of the gooseneck freight car.

[0069] A telescopic chain conveyor 200 from the workshop transports boxed materials 100 from the warehouse to a material attitude adjustment mechanism 2, which adjusts the attitude of the boxed materials 100. A continuously lifting mechanism 3 continuously lifts and transports the boxed materials 100 from the end of the material attitude adjustment mechanism 2 to a lifting and stacking mechanism 4. The lifting and stacking mechanism 4 adjusts the position of the boxed materials 100 and arranges them into rows. The lifting and stacking mechanism 4 pushes the rows of boxed materials 100 into the carriage at once for stacking, completing the loading task. After one row of boxed materials 100 is stacked in the carriage, the lifting and stacking mechanism 4 rises to stack the next layer of boxed materials. When the traveling mechanism 1 reaches the carriage entrance, the lidar spatial recognition component 5 scans the entire carriage and then transmits the obtained point cloud data to the control component 6, which calculates the spatial information of the carriage. The control component 6 is located on both sides of the material posture adjustment mechanism 2. The control component 6 receives the data transmitted back from each mechanism, calculates the data, generates control commands, and controls the actions of each mechanism.

[0070] The various mechanisms of the present invention will now be described in detail.

[0071] Combination Figures 5 to 7 According to an embodiment of the present invention, the traveling mechanism 1 includes at least multiple sets of traveling wheel mechanisms and frame assemblies 101. Each set of traveling wheel mechanisms includes at least a steering wheel assembly 102 and an auxiliary wheel assembly 103. In this embodiment, four sets of traveling wheel mechanisms are exemplary. In some embodiments, there may be six, eight, or more sets of traveling wheel mechanisms. According to an embodiment of the present invention, the steering wheel assembly 102 is configured to reciprocate vertically. The auxiliary wheel assembly 103 is configured to reciprocate vertically. When the traveling mechanism 1 travels within the carriage, the steering wheel assembly 102 and auxiliary wheel assembly 103 of the multiple sets of traveling wheel mechanisms reciprocate vertically across the steps of the workshop platform and the carriage entrance, as well as the gooseneck steps 300 within the gooseneck carriage.

[0072] The traveling wheel mechanism is either wheeled or tracked. In this embodiment of the invention, the traveling wheel mechanism is wheeled. Specifically, multiple sets of traveling wheel mechanisms are installed below the frame assembly. The steering wheel assembly 102 of each set of traveling wheel mechanisms includes: a first support frame 1021, a first gear 1027, a first rack 1028, a first lifting motor 1029, a first linear guide rail 1025, a first slider 1026, a third support frame 10210, a steering mechanism 10211, a steering motor 1024, a traveling motor 1022, and a first traveling wheel 1023.

The first gear 1027 is connected to the output shaft of the first lifting motor 1029. The body of the first lifting motor 1029 is fixed to the frame assembly 101. The first linear guide rail 1025 and the first rack 1028 are both fixedly connected to the first support frame 1021. The first slider 1026 is mounted on the first linear guide rail 1025 and is also fixedly connected to the frame assembly 101. The first traveling wheel 1023 is connected to the first support frame 1021. Specifically, the first support frame 1021 is connected to the steering mechanism 10211, the steering mechanism 10211 is connected to the third support frame 10210, and the first traveling wheel 1023 is connected to the third support frame 10210, thereby connecting the first traveling wheel 1023 to the first support frame 1021 through the third support frame 10210 and the steering mechanism 10211.

[0073] According to an embodiment of the present invention, a first lifting motor 1029 drives a first gear 1027 to rotate, and a first rack 108 reciprocates in the vertical direction in response to the first gear 1027, thereby driving the first support frame 1021 and the first traveling wheel 1023 to reciprocate in the vertical direction, thus enabling the first traveling wheel 1023 to rise or fall and cross the gooseneck step 300 or the platform step. When the first rack 1028 reciprocates in the vertical direction in response to the first gear 1027, the first linear guide rail 1025 reciprocates in the vertical direction relative to the first slider 1026.

[0074] According to an embodiment of the present invention, a steering motor 1024 and a travel motor 1022 are mounted on the third support frame 10210. A steering mechanism 10211 is connected to the output shaft of the steering motor 1024. The steering mechanism 10211 responds to the rotation of the steering motor 1024, driving the third support frame 10210 to rotate, thereby steering the first travel wheel 1023. The travel motor 1022 drives the first travel wheel 1023 to travel.

[0075] According to an embodiment of the present invention, the auxiliary wheel assembly 103 of each set of walking wheel mechanisms includes: a second support frame 1031, a second gear 1035, a second rack 1036, a second lifting motor 1037, a second linear guide rail 1033, a second slider 1034, and a second walking wheel 1032. The second rack 1036 is fixed on the second support frame 1031. The second gear 1035 meshes with the second rack 1036. The second gear 1035 is connected to the output shaft of the second lifting motor 1037. The body of the second lifting motor 1037 is fixed to the frame assembly 101. The second walking wheel 1032 is connected to the second support frame 1031. The second linear guide rail 1033 and the second rack 1036 are both fixed to the second support frame 1031. The second slider 1034 is mounted on the second linear guide rail 1033 and is also fixedly connected to the frame assembly 101.

[0076] According to an embodiment of the present invention, the second lifting motor 1037 drives the second gear 1035 to rotate, and the second rack 1036 reciprocates in the vertical direction in response to the second gear 1035, thereby driving the second support frame 1031 and the second traveling wheel 1032 to reciprocate in the vertical direction, thereby enabling the second traveling wheel 1032 to rise or fall and cross the gooseneck step 300 or the platform step. When the second rack 1036 reciprocates in the vertical direction in response to the second gear 1035, the second linear guide rail 1033 reciprocates in the vertical direction relative to the second slider 1034.

[0077] In this embodiment, the first traveling wheel 1023 and the second traveling wheel 1032 are rollers. In some embodiments, the first traveling wheel 1023 and the second traveling wheel 1032 can be tracks.

[0078] The steering wheel assembly 102 and the auxiliary wheel assembly 103 of this invention cooperate to traverse steps (gooseneck steps 300, platform steps, or any other type of step). Specifically, when the steering wheel assembly 102 needs to rise to the step, the auxiliary wheel assembly 103 will temporarily provide support. Once the steering wheel assembly 102 reaches the step and is subjected to force, the auxiliary wheel assembly 103 will ascend the step in the same way. In this embodiment, a total of four sets of walking wheel mechanisms are fixed to the lower part of the frame assembly 101 to complete the action of the walking mechanism 1 traversing steps in a horizontal situation.

[0079] Combination Figures 8 to 12According to an embodiment of the present invention, the material posture adjustment mechanism 2 includes a box-pulling assembly 201, a box-receiving assembly 202, a flipping assembly 203, a roller conveyor assembly 204, a chain-circulating box-pushing assembly 205, a liftable lateral blocking assembly 206, a turntable assembly 207, a linear module box-pushing assembly 208, a discharge roller assembly 209, a buffer assembly 210, and a box-pulling and box-receiving connecting frame 211. The box-pulling assembly 201 is used to pull the box-type material 100 conveyed by the telescopic chain conveyor 200 to the box-receiving assembly 202. The box-pulling and box-receiving connecting frame 211 is used to connect the box-pulling assembly 201 and the box-receiving assembly 202. The flipping assembly 203 is used to flip the box-type material 100 on the box-receiving assembly 202 to the roller conveyor assembly 204. The roller conveyor assembly 204 is used to convey the box-type material 100 to the chain-circulating box-pushing assembly 205. The chain-circulating box-pushing assembly 205 is used to convey the box-type material 100 to the turntable assembly 207. A turntable assembly 207 is used to receive and rotate the box-shaped material 100. A linear module pusher assembly 208 is used to push the box-shaped material on the turntable assembly 207 to the discharge roller assembly 209. The discharge roller assembly 209 is used to receive the box-shaped material 100 pushed out from the turntable assembly 207.

[0080] According to an embodiment of the present invention, the box-pulling assembly 201 includes a pulling rod 2011, a third gear 2012, a third rack 2013, a third linear guide rail 2014, a third slider 2016, and a first motor 2015. One end of the pulling rod 2011 is connected to the body of the first motor 2015, the output shaft of the first motor 2015 is connected to the third gear 2012, the third gear 2012 meshes with the third rack 2013, and the third rack 2013 is fixed on the box-pulling and box-connecting frame 211. The third slider 2016 is mounted on the third linear guide rail 2014, and is fixed to the pulling rod 2011 and the body of the first motor 2015. The third linear guide rail 2014 is fixed on the box-pulling and box-connecting frame 211. The third gear 2012 responds to the rotation of the first motor 2015. The third gear 2012 reciprocates horizontally on the third rack 2013, driving the first motor 2015 and the pull rod 2011 to reciprocate horizontally. When the pull rod 2011 reciprocates horizontally, the third slider 2016 reciprocates horizontally on the third linear guide 2014. The horizontal reciprocating motion of the pull rod 2011 pulls the box-shaped material 100, which has been conveyed to the box-receiving assembly 201, to the receiving assemblies 202 on both sides.

[0081] According to an embodiment of the present invention, the receiving box assembly 202 includes a first shelf 2021, a fourth gear 2024, a fourth rack 2022, a fourth linear guide rail 2023, a fourth slider 2026, and a second motor 2025. One end of the first shelf 2021 is connected to the body of the second motor 2025. The output shaft of the second motor 2025 is connected to the fourth gear 2024. The fourth gear 2024 meshes with the fourth rack 2022, which is fixed to the receiving box connecting frame 211. The fourth slider 2026 is mounted on the fourth linear guide rail 2023 and fixed to the first shelf 2021. The fourth linear guide rail 2023 is fixed to the receiving box connecting frame 211. The fourth gear 2024 responds to the rotation of the second motor 2025 and reciprocates horizontally on the fourth rack 2022, driving the second motor 2025 and the first shelf 2021 to reciprocate horizontally. When the first carrier 2021 reciprocates horizontally, the fourth slider 2026 reciprocates horizontally on the fourth linear guide 2023. The first carrier 2021 reciprocates horizontally to adapt to the positional changes of the telescopic chain conveyor 200. The box-pulling assembly 201, via the pulling rod 2011, reciprocates horizontally to pull the box-shaped material 100 conveyed to the box-pulling assembly 201 onto the first carrier 2021 of the receiving assemblies 202 on both sides.

[0082] According to an embodiment of the present invention, the flipping assembly 203 includes a second carrier 2031, a belt conveyor 2033, a flipping mechanism 2034, and a third motor 2032. The belt conveyor 2033 is vertically fixed to the second carrier 2031, which is connected to the first carrier 2021. The second carrier 2031 and the first carrier 2021 are complementary in shape and have a gap in the horizontal plane, such that when the second carrier 2031 is in the horizontal plane, its upper surface is aligned with the upper surface of the first carrier 2021. The second carrier 2031 receives the box-shaped materials 100 on the first carrier 2021 to maximize the deviation space of the telescopic chain conveyor 200 and to maximize the adaptability to parking deviations. The flipping mechanism 2034 is fixed to the belt conveyor 2033, and the output shaft of the third motor 2032 is connected to the flipping mechanism 2034. The flipping mechanism 2034 responds to the rotation of the third motor 2032, driving the belt conveyor 2033 and the second carrier 2031 to flip and lift the box-shaped material 100 on the second carrier 2031 onto the belt conveyor 2033. The belt conveyor 2033 is used to transport the flipped box-shaped material 100 to the roller conveyor assembly 204.

[0083] like Figure 11As shown, according to an embodiment of the present invention, a chain-driven circulating box-pushing assembly 205 is arranged in the gap between the rollers of a roller conveyor assembly 204, which conveys the box-type material 100 onto the chain-driven circulating box-pushing assembly 205. The chain-driven circulating box-pushing assembly 205 includes a chain 2051, a first push rod 2052, a second push rod 2053, and a fourth motor 2054. The fourth motor 2054 is connected to the chain 2051 and drives the chain 2051 to reciprocate. The first push rod 2052 and the second push rod 2053 are arranged on the chain 2051 and reciprocate with the chain 2051. When the box-type material 100 is conveyed to the chain-driven circulating box-pushing assembly 205, the first push rod 2052 and the second push rod 2053 reciprocate, pushing the box-type material 100 forward and pushing it onto the turntable assembly 207.

[0084] According to an embodiment of the present invention, a liftable lateral blocking assembly 206 is arranged above the chain-driven circulating push box assembly 205. The liftable lateral blocking assembly 206 includes a roller stop 2061, which is configured to move vertically upwards and downwards, and when the roller stop 2061 descends vertically, it blocks the box material 100 pushed forward by the first push rod 2052 or the second push rod 2053, causing the box material 100 to tip over.

[0085] Specifically, the liftable lateral blocking assembly 206 also includes a roller stop drive chain 2062 and a fifth motor 2063. The roller stop 2061 is connected to the roller stop drive chain 2062, and the fifth motor 2063 is connected to the roller stop drive chain 2062. The fifth motor 2063 drives the roller stop drive chain 2062 to reciprocate, and the roller stop drive chain 2062 drives the roller stop 2061 to move vertically up and down. When the roller stop 2061 descends vertically, the box-type material 100 overturns under the pushing action of the first push rod 2052 or the second push rod 2053 and the blocking action of the roller stop 2061.

[0086] According to an embodiment of the present invention, the buffer assembly 210 is arranged above the chain-driven circulating push box assembly and located at the rear end of the liftable lateral blocking assembly 206. The buffer assembly 210 includes an arc-shaped plate 2101, an elastic belt 2102, and a nitrogen spring 2103. When the roller stop bar 2061 prevents the box-type material 100 from tipping over, the buffer assembly 210 cushions the box-type material 100, preventing damage to the box-type material 100 during the tipping process.

[0087] like Figure 12 As shown, according to an embodiment of the present invention, the turntable assembly 207 is arranged at the front end of the chain circulation push box assembly 205 to receive the box material 100 and rotate the box material 100.

[0088] A linear module pusher assembly 208 is used to push box-type material 100 from turntable assembly 207 to discharge roller assembly 209. The linear module pusher assembly 208 includes a third push rod 2081, a sixth motor 2082, a linear module 2083, and a seventh motor 2084. The third push rod 2081 is configured to reciprocate vertically and, in response to the linear module 2083, push the box-type material 100 from turntable assembly 207.

[0089] Specifically, the third push rod 2081 is connected to the sixth motor 2082, which drives the third push rod 2081 to reciprocate vertically. The sixth motor 2082 is fixed to the slider of the linear module 2083, which is connected to the seventh motor 2084. After the box material 100 has finished adjusting its posture, the third push rod 2081 swings downward under the action of the sixth motor 2082 and pushes the box material 100 forward under the action of the linear module 2083 to the discharge roller assembly 209, waiting for the next station to receive the material. The discharge roller assembly 209 is used to receive the box material 100 pushed out from the turntable assembly 207. After the box-shaped material 100 enters the station of the box-pulling assembly 201, it is pushed left and right by the pulling rod 2011 onto the receiving assembly 202 located on both sides of the telescopic chain conveyor 200. Then, the tilting assembly 203 tilts it upward by 90°, flipping the box-shaped material 100 to the inlets at both ends of the roller conveyor assembly 204. The belt conveyor 2033 of the tilting assembly 203 then transports it onto the roller conveyor assembly 204. The box-shaped material 100 is then conveyed by the roller conveyor assembly 204 to the chain circulating box-pushing assembly 205. On the chain circulating box-pushing assembly 205, the first push rod 2052 and the second push rod 2053 reciprocate to push the box-shaped material 100 onto the turntable assembly 207. The turntable assembly 207 rotates the box-shaped material 100 by 90°, and the linear module box-pushing assembly 208 pushes the box-shaped material 100 onto the discharge roller assembly 209, waiting to be picked up.

[0090] The chain circulation pusher assembly 205, the liftable lateral blocking assembly 206, and the turntable assembly 207 of the material posture adjustment mechanism 2 of the present invention cooperate with each other to achieve four posture adjustments for the box-type material 100. The specific process is as follows:

[0091] 1) The liftable horizontal blocking component 206 does not descend to block the upper part of the box material 100. The chain circulation pushing component 205 directly pushes the box material 100 onto the turntable component 207. The turntable component 207 rotates 90° to achieve the first posture of the box material 100.

[0092] 2) The liftable horizontal blocking component 206 does not descend to block the upper part of the box material 100. The chain circulation pushing component 205 directly pushes the material onto the turntable component 207. The turntable component 207 does not rotate 90°, thus realizing the second posture of the box material 100.

[0093] 3) The liftable lateral blocking component 206 lowers to block the upper part of the box material 100. The first push rod 2052 or the second push rod 2053 of the chain circulation box pushing component 205 pushes the lower part of the box material 100. The roller stop bar 2061 of the liftable lateral blocking component 206 blocks the upper part of the box material 100, preventing the box material 100 from tilting backward by 90°. Then, the second push rod 2053 or the first push rod 2052 on the chain circulation box pushing component 205 pushes the box material 100 onto the turntable component 207. The turntable component 207 does not rotate, realizing the third posture of the box material 100.

[0094] 4) The liftable lateral blocking component 206 lowers to block the upper part of the box material 100. The first push rod 2052 or the second push rod 2053 of the chain circulation box pushing component 205 pushes the lower part of the box material 100. The roller stop bar 2061 of the liftable lateral blocking component 206 blocks the upper part of the box material 100, preventing the box material 100 from tilting backward by 90°. Then, the second push rod 2053 or the first push rod 2052 on the chain circulation box pushing component 205 pushes the box material 100 onto the turntable component 207. The turntable component 207 rotates 90° to achieve the fourth posture of the box material 100.

[0095] When the buffer assembly 210 prevents the box material 100 from tilting backward by 90°, it can effectively reduce the impact force of the box material 100 tilting backward on the roller conveyor assembly 204.

[0096] Combination Figures 13 to 19According to an embodiment of the present invention, the liftable continuous lifting mechanism 3 includes a mounting plate assembly 301, a first annular guide rail 302, a second annular guide rail 303, a double rail assembly 304, a shelf transmission assembly, a shelf assembly 306, a lifting drive motor 309, a transmission rack 312, a transmission gear 310, a linear rail 313, a sliding block 311, and a frame 314. The shelf transmission assembly includes a drive sprocket 307, a drive sprocket motor 308, a chain tensioner 305, and a transmission chain 315. The shelf transmission assembly is located at a different level from the first annular guide rail 302, the second annular guide rail 303, and the double rail assembly 304. The first annular guide rail 302, the second annular guide rail 303, and the double rail assembly 304 are fixed to one side of the mounting plate assembly 301, and the first annular guide rail 302 and the second annular guide rail 303 are on the same plane. The double-track assembly 304 is located on the plane where the first annular guide rail 302 and the second annular guide rail 303 are located, between the mounting plate assembly 301, i.e., the double-track assembly 304, and the first annular guide rail 302 and the second annular guide rail 303 are arranged in layers. The shelf assembly 306 is configured to reciprocate along the first annular guide rail 302, the second annular guide rail 303 and the double-track assembly 304, and the shelf assembly 306 is always in a horizontal state. The drive chain 315 is arranged around the outer periphery of the drive sprocket 307 and the chain tensioner 305, and the drive chain 315 is connected to the shelf assembly 306 (the connection method between the drive chain 315 and the shelf assembly 306 is described below).

[0097] The chain tension wheel 305 is connected to the mounting plate assembly 301. The drive sprocket motor 308 is fixed on the mounting plate assembly 301. The output shaft of the drive sprocket motor 308 is connected to the drive sprocket 307, driving the drive sprocket 307 to drive the transmission chain 315 and the rack assembly 306 to reciprocate along the first annular guide rail 302, the second annular guide rail 303 and the double track assembly 304.

[0098] like Figure 16 According to an embodiment of the present invention, the shelf assembly 306 includes a comb-shaped shelf 30601, a wheel train 30602, an intermediate shaft 30606, a wheel train seat 30605, a horizontal retaining wheel plate 30603, a chain mounting seat 30604, a first horizontal retaining wheel 30607, a second horizontal retaining wheel 30609, a third horizontal retaining wheel 30610, and a fourth horizontal retaining wheel 30608. One end of the intermediate shaft 30606 is fixedly connected to the comb-shaped shelf 30601. The wheel train seat 30605 is mounted on the intermediate shaft 30606, and the wheel train seat 30605 fixes the wheel train 30602. The wheel train seat 30605 is configured to rotate relative to the intermediate shaft 30606, for example, by mounting a bearing between the wheel train seat 30605 and the intermediate shaft 30606.

[0099] The present invention has two rows of walking wheel trains 30602 arranged axially along the parallel intermediate shaft 30606. Each row includes walking wheels arranged opposite each other in an axial direction perpendicular to the intermediate shaft 30606. The two rows of walking wheel trains 30602 are sandwiched between the first annular guide rail 302 and the second annular guide rail 303, driving the rack assembly 306 to reciprocate along the first annular guide rail 302, the second annular guide rail 303, and the double track assembly 304. Figure 17 As shown.

[0100] The walking wheel system 30602 is sandwiched between the first annular guide rail 302 and the second annular guide rail 303. During the process of driving the rack assembly 306 to reciprocate along the first annular guide rail 302, the second annular guide rail 303 and the double track assembly 304, the walking wheel system 30602 rolls along the surface of the first annular guide rail 302 and the second annular guide rail 303. When it reaches the turning position, the walking wheel system seat 30605 rotates relative to the intermediate shaft 30606, while the intermediate shaft 30606 does not rotate, so as to keep the comb-shaped rack 30601 of the rack assembly 306 always in a horizontal state.

[0101] The other end of the intermediate shaft 30606 is fixed to a horizontal retaining wheel plate 30603. A first horizontal retaining wheel 30607, a second horizontal retaining wheel 30609, a third horizontal retaining wheel 30610, and a fourth horizontal retaining wheel 30608 are mounted on the horizontal retaining wheel plate 30603. The first horizontal retaining wheel 30607 and the fourth horizontal retaining wheel 30608 are axially horizontal, and their wheel sides (non-rolling surfaces) are both located within a first vertical plane. The second horizontal retaining wheel 30609 and the third horizontal retaining wheel 30610 are axially horizontal, and their wheel sides (non-rolling surfaces) are both located within a second vertical plane. The distance between the first vertical plane and the horizontal retaining wheel plate 30603 is greater than the distance between the second vertical plane and the horizontal retaining wheel plate 30603. Specifically, the first horizontal retaining wheel 30607 and the fourth horizontal retaining wheel 30608 are fixed to the horizontal retaining wheel plate 30603 via a long shaft 30616. The second horizontal retaining wheel 30609 and the third horizontal retaining wheel 30610 are fixed to the horizontal retaining wheel plate 30603 via a short shaft 30617. The first horizontal retaining wheel 30607 and the fourth horizontal retaining wheel 30608 are arranged along a first direction, and the second horizontal retaining wheel 30609 and the third horizontal retaining wheel 30610 are arranged along a second direction, with the first direction perpendicular to the second direction. In this embodiment, the first horizontal retaining wheel 30607 and the fourth horizontal retaining wheel 30608 are arranged horizontally, and the second horizontal retaining wheel 30609 and the third horizontal retaining wheel 30610 are arranged vertically.

[0102] Combination Figure 18 , Figure 19 and Figure 20The multi-track assembly 304 includes a vertical track 30403, a first horizontal track 30408, a second horizontal track 30401, a first arc-shaped track 30405, and a second arc-shaped track 30404. A guide block 30402 is provided between the first arc-shaped track 30405 and the second arc-shaped track 30404. A first guide boss 30407 and a second guide boss 30406 are provided on the guide block 30402. A first groove 30411 is formed between the first guide boss 30407 and the second guide boss 30406. The vertical track 30403 extends to the first guide boss 30407. A gap is formed between the first guide boss 30407 and the first arc-shaped track 30405, and a gap is formed between the second guide boss 30406 and the second arc-shaped track 30404. A guide groove 30414 is formed between the first horizontal rail 30408 ​​and the second horizontal rail 30401. A third guide boss 30410 is provided between the first arc-shaped rail 30405 and the first horizontal rail 30408, and a fourth guide boss 30409 is provided between the second arc-shaped rail 30404 and the second horizontal rail 30401. The cross-sections of the third guide boss 30410 and the fourth guide boss 30409 are L-shaped, and the third guide boss 30410 and the fourth guide boss 30409 are arranged opposite to each other, so that a second groove 30412 and a third groove 30413 are formed between the third guide boss 30410 and the fourth guide boss 30409. The width D1 of the second groove 30412 is smaller than the width D2 of the third groove 30413. Figure 18 and Figure 20 As shown. The third guide boss 30410 abuts against the first horizontal rail 30408, and the fourth guide boss 30409 abuts against the second horizontal rail 30401. The width of the guide groove 30414 formed between the first horizontal rail 30408 ​​and the second horizontal rail 30401 is the same as the width D1 of the second groove 30412, as shown. Figure 18 and Figure 19 As shown.

[0103] In a preferred embodiment, the first arc-shaped rail 30405, the second arc-shaped rail 30404, the guide block 30402, the first guide boss 30407, the second guide boss 30406, the third guide boss 30410, and the fourth guide boss 30409 are fixed to the mounting plate assembly 301 as integrally formed parts.

[0104] When the shelf assembly 306 reciprocates along the first annular guide rail 302 and the second annular guide rail 303, the first horizontal retaining wheel 30607, the second horizontal retaining wheel 30609, the third horizontal retaining wheel 30610 and the fourth horizontal retaining wheel 30608 reciprocate along the double track assembly 304, so that the comb-shaped shelf 30601 remains horizontal.

[0105] like Figure 19As shown in the example, the shelf assembly 306 reciprocates counterclockwise, and in some embodiments the shelf assembly 306 reciprocates clockwise.

[0106] In this embodiment, taking the counterclockwise reciprocating motion of the shelf assembly 306 as an example, when the vertical rail 30403 on the right side of the shelf assembly 306 moves upward in the vertical direction, the first horizontal retaining wheel 30607 (located on the right side of the vertical rail 30403), the third horizontal retaining wheel 30610, and the second horizontal retaining wheel 30609 (located on the left side of the vertical rail 30403) clamp the right vertical rail 30403 and move upward.

[0107] When the shelf assembly 306 moves upward from the right vertical rail 30403 and then horizontally to the left to turn, the third horizontal retaining wheel 30610 enters the first guide boss 30407 and the second guide boss 30406 to form a first groove 30411, guiding the third horizontal retaining wheel 30610 into the third groove 30413 between the third guide boss 30410 and the fourth guide boss 30409. Simultaneously, the fourth horizontal retaining wheel 30608 enters the gap between the second guide boss 30406 and the second arc-shaped rail 30404, guiding the fourth horizontal retaining wheel 30608 into the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409. Simultaneously, the first horizontal retaining wheel 30607 enters the gap between the first guide boss 30407 and the first arc-shaped rail 30405, guiding the first horizontal retaining wheel 30607 into the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409. Simultaneously, the second horizontal retaining wheel 30609 enters the first groove 30411 formed between the first guide boss 30407 and the second guide boss 30406, guiding the second horizontal retaining wheel 30609 into the third groove 30413 between the third guide boss 30410 and the fourth guide boss 30409.

[0108] When the shelf assembly 306 moves horizontally to the left from above, the fourth horizontal retaining wheel 30608 and the first horizontal retaining wheel 30607 enter the guide groove 30414 between the first horizontal rail 30408 ​​and the second horizontal rail 30401 through the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409. The fourth horizontal retaining wheel 30608 and the first horizontal retaining wheel 30607 move horizontally to the left along the guide groove 30414. At the same time, the wheel side (non-rolling surface) of the third horizontal retaining wheel 30610 slides horizontally to the left relative to the first horizontal rail 30408, and the wheel side (non-rolling surface) of the second horizontal retaining wheel 30609 slides horizontally to the left relative to the side of the second horizontal rail 30401.

[0109] In some preferred embodiments, there is a small gap between the wheel side (non-rolling surface) of the third horizontal retaining wheel 30610 and the side of the first horizontal rail 30408, and a small gap between the wheel side (non-rolling surface) of the second horizontal retaining wheel 30609 and the side of the second horizontal rail 30401.

[0110] When the shelf assembly 306 moves horizontally to the left from above and turns downwards along the left vertical rail 30403, the fourth horizontal retaining wheel 30608 enters the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409, guiding the fourth horizontal retaining wheel 30608 into the gap between the first guide boss 30407 and the first arc-shaped rail 30405. Simultaneously, the second horizontal retaining wheel 30609 enters the third groove 30413 between the third guide boss 30410 and the fourth guide boss 30409, guiding the second horizontal retaining wheel 30609 into the first groove 30411 formed between the first guide boss 30407 and the second guide boss 30406. Simultaneously, the third horizontal retaining wheel 30610 enters the third groove 30413 between the third guide boss 30410 and the fourth guide boss 30409, guiding the third horizontal retaining wheel 30610 into the first groove 30411 formed between the first guide boss 30407 and the second guide boss 30406. Simultaneously, the first horizontal retaining wheel 30607 enters the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409, guiding the first horizontal retaining wheel 30607 into the gap between the second guide boss 30406 and the second arc-shaped rail 30404.

[0111] When the vertical rail 30403 on the left side of the shelf assembly 306 moves downward in the vertical direction, the fourth horizontal retaining wheel 30608 (located on the left side of the vertical rail 30403), together with the third horizontal retaining wheel 30610 and the second horizontal retaining wheel 30609 (located on the right side of the vertical rail 30403), clamp the left vertical rail 30403 and move downward.

[0112] When the shelf assembly 306 moves downwards from the left vertical rail 30403 and then horizontally to the right to turn, the second horizontal retaining wheel 30609 enters the first guide boss 30407 and the second guide boss 30406 to form a first groove 30411, guiding the second horizontal retaining wheel 30609 into the third groove 30413 between the third guide boss 30410 and the fourth guide boss 30409. Simultaneously, the first horizontal retaining wheel 30607 enters the gap between the second guide boss 30406 and the second arc-shaped rail 30404, guiding the first horizontal retaining wheel 30607 into the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409. Simultaneously, the fourth horizontal retaining wheel 30608 enters the gap between the first guide boss 30407 and the first arc-shaped rail 30405, guiding the fourth horizontal retaining wheel 30608 into the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409. Simultaneously, the third horizontal retaining wheel 30610 enters the first groove 30411 formed between the first guide boss 30407 and the second guide boss 30406, guiding the third horizontal retaining wheel 30610 into the third groove 30413 between the third guide boss 30410 and the fourth guide boss 30409.

[0113] When the shelf assembly 306 moves horizontally to the right from below, the first horizontal retaining wheel 30607 and the fourth horizontal retaining wheel 30608 enter the guide groove 30414 between the first horizontal rail 30408 ​​and the second horizontal rail 30401 through the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409. The first horizontal retaining wheel 30607 and the fourth horizontal retaining wheel 30608 move horizontally to the right along the guide groove 30414. At the same time, the wheel side (non-rolling surface) of the third horizontal retaining wheel 30610 slides horizontally to the left relative to the second horizontal rail 30401, and the wheel side (non-rolling surface) of the second horizontal retaining wheel 30609 slides horizontally to the left relative to the side of the first horizontal rail 30408. In some preferred embodiments, there is a small gap between the wheel side (non-rolling surface) of the third horizontal retaining wheel 30610 and the side of the second horizontal rail 30401, and a small gap between the wheel side (non-rolling surface) of the second horizontal retaining wheel 30609 and the side of the first horizontal rail 30408.

[0114] When the shelf assembly 306 moves horizontally to the right from below and turns upwards along the right-side vertical rail 30403, the first horizontal retaining wheel 30607 enters the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409, guiding the first horizontal retaining wheel 30607 into the gap between the first guide boss 30407 and the first arc-shaped rail 30405. Simultaneously, the third horizontal retaining wheel 30610 enters the third groove 30413 between the third guide boss 30410 and the fourth guide boss 30409, guiding the third horizontal retaining wheel 30610 into the first groove 30411 formed between the first guide boss 30407 and the second guide boss 30406. Simultaneously, the second horizontal retaining wheel 30609 enters the third groove 30413 between the third guide boss 30410 and the fourth guide boss 30409, guiding the second horizontal retaining wheel 30609 into the first groove 30411 formed between the first guide boss 30407 and the second guide boss 30406. Simultaneously, the fourth horizontal retaining wheel 30608 enters the second groove 30412 between the third guide boss 30410 and the fourth guide boss 30409, guiding the fourth horizontal retaining wheel 30608 into the gap between the second guide boss 30406 and the second arc-shaped rail 30404.

[0115] When the vertical rail 30403 on the right side of the shelf assembly 306 moves upward in the vertical direction, the first horizontal retaining wheel 30607 (located on the right side of the vertical rail 30403), the third horizontal retaining wheel 30610, and the second horizontal retaining wheel 30609 (located on the left side of the vertical rail 30403) clamp the vertical rail 30403 on the right side and move upward.

[0116] Thus, the first horizontal holding wheel 30607, the second horizontal holding wheel 30609, the third horizontal holding wheel 30610, and the fourth horizontal holding wheel 30608 reciprocate along the double-track assembly 304, keeping the comb-shaped rack 30601 horizontal. Each rack assembly 306 of this invention remains horizontal and performs cyclical movement, achieving the purpose of horizontally transferring the boxed materials 100 to different heights, enabling the palletizing platform 410 (described below) to float and receive materials at different palletizing heights, achieving continuous automatic material discharge.

[0117] Back Figure 16According to an embodiment of the present invention, a chain mounting seat 30604 is fixed on the walking wheel train seat 30605. The chain mounting seat 30604 is hinged to the transmission chain 315, thereby connecting the transmission chain 315 to the rack assembly 306. For example, the chain mounting seat 30604 and the transmission chain 315 are hinged by a pin. The transmission chain 315 is arranged around the outer periphery of the drive sprocket 307 and the chain tensioner 305. The drive sprocket motor 308 drives the drive sprocket 307 to rotate, and the drive sprocket 307 drives the transmission chain 315 to circulate. The transmission chain 315 drives the rack assembly 306 to circulate and reciprocate along the first annular guide rail 302, the second annular guide rail 303, and the double track assembly 304 through the chain mounting seat 30604.

[0118] Back Figure 14 and Figure 15 According to an embodiment of the present invention, a frame 314 is mounted on the other side of the mounting plate assembly 301, and a lifting drive motor 309 is fixed on the frame 314. A transmission rack 312 is also provided on the mounting plate assembly 301, and the output shaft of the lifting drive motor 309 is connected to a transmission gear 310, with the transmission rack 312 meshing with the transmission gear 310. A linear rail 313 is fixed on the other side of the mounting plate assembly 301, and a sliding block 311 is mounted on the linear rail 313, with the sliding block 311 fixedly connected to the frame 314. The frame 314 is fixed in a preset position. The transmission gear 310 rotates in response to the lifting drive motor 309, and the transmission rack 312 reciprocates vertically relative to the transmission gear 310, driving the mounting plate assembly 301 connected thereto to reciprocate vertically relative to the fixed-position frame 314. The frame 314 is fixed to the frame assembly 101 of the traveling mechanism 1. When the mounting plate assembly 301 reciprocates vertically relative to the frame 314, the mounting plate assembly 301 is raised and lowered, thereby adjusting the vertical height of the continuously lifting mechanism 3, increasing the working range and improving loading efficiency. When the mounting plate assembly 301 reciprocates vertically relative to the frame 314, the linear rail 313 reciprocates vertically relative to the sliding block 311.

[0119] like Figure 21 , Figure 22 As shown, the gaps between the rack assembly 306 of the lifting and lowering continuous lifting mechanism 3 and the discharge roller assembly 209 of the material posture adjustment mechanism 2 are staggered, and the two will not interfere with each other. When the rack assembly 306 rises continuously, it realizes continuous material picking up from the discharge roller assembly 209.

[0120] The rack assembly 306 of the liftable continuous lifting mechanism 3 and the receiving roller assembly 402 (described below) of the lifting and palletizing mechanism 4 operate with alternating gaps, preventing interference between them. When the rack assembly 306 descends continuously, continuous material is fed onto the receiving roller assembly 402. Furthermore, the height of the liftable continuous lifting mechanism 3 is adjustable, eliminating the need for the palletizing platform 410 (described below) to return to the receiving area, thus improving loading efficiency.

[0122] According to an embodiment of the present invention, the receiving roller assembly 402 is connected to the liftable continuous lifting mechanism 3 and is used to receive the box-shaped material 100 conveyed by the liftable continuous lifting mechanism 3, such as... Figure 21 As shown.

[0123] The first linear pusher module assembly 403 is used to push the box-type material 100 on the receiving roller assembly 402 toward the palletizing platform 410. The conveyor roller assembly 405 is arranged between the receiving roller assembly 402 and the palletizing platform 410, and is used to convey the box-type material 100 from the receiving roller assembly 402 to the palletizing platform 410.

A second linear box-pushing module assembly 409, arranged on the palletizing platform 410, is used to push out the rows of box-type materials 100 arranged on the palletizing platform 410 and stack them in the carriage. A two-stage lifting assembly 401 is used to vertically lift the palletizing platform 410.

[0125] like Figure 24As shown, according to an embodiment of the present invention, the two-stage lifting assembly 401 includes a column 40101, a first lifting seat 40106, a first drive motor 40104, a first lifting gear (not shown in the figure), a first lifting rack 40102, a first sliding member 40105, a first linear slide rail 40103, a second lifting seat 40108, a second motor drive motor 40110, a second lifting gear (not shown in the figure), a second lifting rack 40111, a second sliding member 40107, and a second linear slide rail 40109.

The second lifting seat 40108 is connected to the palletizing platform 410 (described below), and the second lifting seat 40108 is configured to reciprocate in the vertical direction relative to the column 40101.

[0126] Furthermore, a first drive motor 40104 is fixed on the first lifting seat 40106. The output shaft of the first drive motor 40104 is connected to a first lifting gear, which meshes with a first lifting rack 40102. The first lifting rack 40102 is fixed to the column 40101.

The first sliding member 40105 is fixed on the first lifting seat 40106, and the first linear slide rail 40103 is fixed on the column 40101. The first drive motor 40104 drives the first lifting gear to rotate, and the first lifting rack 40102 reciprocates in response to the first lifting gear, causing the column 40101 to reciprocate in the vertical direction. When the first lifting rack 40102 reciprocates in response to the first lifting gear, the first sliding member 40105 reciprocates in the vertical direction on the first linear slide rail 40103. A second drive motor 40110 is fixed on the second lifting seat 40108. The output shaft of the second drive motor 40110 is connected to a second lifting gear, which meshes with a second lifting rack 40111. The second lifting rack 40111 is fixed to the column 40101.

The second sliding member 40107 is fixed on the second lifting seat 40108, and the second linear slide rail 40109 is fixed on the column 40101. The second lifting gear responds to the rotation of the second drive motor 40110 and reciprocates vertically on the second lifting rack 40111, driving the second lifting seat 40108 to reciprocate vertically, thereby driving the palletizing platform 410 connected to the second lifting seat 40108 to reciprocate vertically. When the second lifting seat 40108 reciprocates vertically, the second sliding member 40107 reciprocates vertically on the second linear slide rail 40109. When the first drive motor 40104 drives the first lifting gear to rotate on the first lifting rack 40102, the column 40101 rises and falls, realizing the first stage of lifting of the palletizing platform 410. When the second drive motor 40110 drives the first lifting gear to rotate on the second lifting rack 40111, the second lifting seat 40108 reciprocates vertically, realizing the second stage of lifting of the palletizing platform 410. The two-stage lifting configuration effectively increases the palletizing operation range.

The first rod 40301 responds to the first linear push box module 40303 by pushing the box-shaped material 100 on the receiving roller assembly 402 to the conveying roller assembly 405. The material position adjustment assembly 404 includes a first electric cylinder 40401 and a first push plate 40402. The first electric cylinder 40401 is fixed on the mounting frame 40302. The output shaft of the first electric cylinder 40401 is connected to the first push plate 40402, and the first push plate 40402 responds to the first electric cylinder 40401 by adjusting the position of the box-shaped material 100 on the conveying roller assembly 405. The conveyor roller assembly 405 includes a linear bearing box unit 40504, a first electric roller 40501, a first driven roller 40502, and a first belt 40503, all fixed to the conveyor roller assembly 405. The first electric roller 40501 drives the first driven roller 40502 to rotate via the first belt 40503, conveying the boxed material 100, after position adjustment on the conveyor roller assembly 405, to the palletizing platform 410 via the material position adjustment component 404.

The second electric roller 41003 drives the second driven roller 41002 to rotate via the second belt 41004, conveying the boxed material 100 forward. The mounting groove 41009 is fixed to the second lifting seat 40108 of the two-stage lifting assembly 401, thereby connecting the second lifting seat 40108 to the palletizing platform 410.

Specifically, a first bracket 41006 and a second bracket 41006' are fixed on the platform frame 41001, and the guide shaft 41008 is fixed on the first bracket 41006 and the second bracket 41006'. The linear bearing housing unit 40504 of the conveyor roller assembly 405 is sleeved on the guide shaft 41008, and the linear bearing housing unit 40504 is fixed on the mounting bracket 40302. The linear bearing housing unit 40504 is configured to slide vertically relative to the guide shaft 41008, thereby realizing the vertical lifting and lowering of the conveyor roller assembly 405 relative to the palletizing platform 410.

[0129] In a further embodiment, a cable tray 41007 is provided between the first support 41006 and the second support 41006'.

[0130] Combination Figures 26 to 30 In an embodiment of the present invention, a chain reciprocating push box assembly 407, a material blocking assembly 406, a platform width adjustment assembly 408, and a second linear push box module assembly 409 are arranged on the palletizing platform 410.

[0131] The chain reciprocating pusher assembly 407 includes a second pusher plate 40705, a first shaft 40704, a second shaft 40710, a reciprocating chain 40701, a third drive motor 40706, a tension block 40707, a synchronous belt 40708, a synchronous pulley 40709, and a sprocket 40703. The reciprocating chain 40701 is arranged between the first shaft 40704 and the second shaft 40710. The second pusher plate 40705 is fixed on the reciprocating chain 40701. The reciprocating chain 40701 responds to the third drive motor 40706, driving the second pusher plate 40705 to reciprocate in the horizontal direction, pushing the boxed materials 100 on the palletizing platform 410 to both sides and arranging them into rows.

[0132] Specifically, sprockets 40703 are installed on both sides of the first shaft 40704 and the second shaft 40710, respectively. The sprockets 40703 are connected to the output shaft of the third drive motor 40706 via a timing belt 40708 and a timing pulley 40709. A bearing 40702 is installed between the timing pulley 40709 and the first shaft 40704 and the second shaft 40710. The timing belt 40708 is tensioned by a tensioning block 40707.

[0133] The material blocking assembly 406 includes a baffle 40601, a lever 40604, a hinge block 40605, a guide pin 40602, and a tension spring 40603. The baffle 40601 is located at the front end of the palletizing platform 410 and is fixedly connected to one end of the lever 40604. The tension spring 40603 is connected to the end of the lever 40604 that is fixedly connected to the baffle 40601. The hinge block 40605 is hinged to the middle of the lever 40604, and the other end of the lever 40604 is a free end. The baffle 40601 has a slot, and the guide pin 40602 is embedded in the slot. The baffle 40601 can slide up and down relative to the guide pin 40602. When the free end of the lever 40604 is subjected to force and moves downwards (…),… Figure 27 As shown by arrow a), lever 40604 fixes one end of baffle 40601, causing baffle 40601 to lift ( Figure 27 As shown by arrow b), the box-shaped material 100 is blocked from moving forward and is arranged neatly. When the force on the free end of lever 40604 disappears, the tension spring 40603 pulls one end of the fixed baffle 40601 of lever 40604 downward, causing the baffle 40601 to reset. The force on the free end of lever 40604 is provided by the second linear push box module assembly 409, which is described in detail below.

[0134] Combination Figure 26 , Figure 29 Platform width adjustment components 408 are distributed on both sides of the palletizing platform 410. Platform width adjustment components 408 include a third bracket 40801, a third linear slide rail 40802, and multiple first widening rods 40807. The multiple first widening rods 40807 are vertically fixed to the third bracket 40801. The third linear slide rail 40802 is fixed to the third bracket 40801. A third sliding member 40803 is installed on the third linear slide rail 40802, and the third sliding member 40803 is connected to the second linear pusher module assembly 409.

[0135] According to an embodiment of the present invention, a fourth linear slide rail 40804 is fixed on at least two first widening rods 40807, and a fourth sliding member 40805 is installed on the fourth linear slide rail 40804.

[0136] Multiple second widening rods 41010 are arranged on both sides of the platform frame 41001. Multiple first widening rods 40807 are arranged in a cross pattern with the multiple second widening rods 41010, and a fourth sliding member 40805 is fixed on the second widening rods 41010.

[0137] According to an embodiment of the present invention, at least one end of a second widening rod 41010 is provided with a second electric cylinder 41005, and the output shaft of the second electric cylinder 41005 is connected to a third bracket 40801. Specifically, the third bracket 40801 has a mounting hole 40808, and the output shaft of the second electric cylinder 41005 is connected to the third bracket 40801 through the mounting hole 40808.

[0138] When the output shaft of the second electric cylinder 41005 extends or retracts, it pushes the platform width adjustment component 408 away from or towards the platform frame 41001, adjusting the width of the palletizing platform 410. This invention allows the platform width adjustment component 408 to move left and right according to the width of the carriage, adapting to carriages of different widths.

[0139] Furthermore, a plurality of first universal balls 40806 are arranged on the upper surface of the first widening rod 40807, and a plurality of second universal balls 41011 are arranged on the upper surface of the second widening rod 41010, so as to facilitate the arrangement of the box material 100 on both sides of the palletizing platform 410.

[0140] like Figure 30 As shown, according to an embodiment of the present invention, the second linear push-box module assembly 409 includes a second rod 40901, a third rod 40903, a fourth bracket 40909, a fifth bracket 40907, and a second linear push-box module 40910. The second rod 40901 responds to the second linear push-box module 40910 to push out rows of boxed materials 100 arranged on the palletizing platform 410, stacking them inside the vehicle compartment.

[0141] Specifically, according to an embodiment of the present invention, the second linear pusher module 40910 is fixed on the platform frame 41001. A fourth bracket 40909 is provided on the second linear pusher module 40910, for example, the fourth bracket 40909 is mounted on the slider of the second linear pusher module 40910. A third electric cylinder 40902 is fixed on the fourth bracket 40909, and the output shaft of the third electric cylinder 40902 is fixed to the second rod 40901. A fifth linear slide rail 40904 is fixed to both ends of the second rod 40901, and a fifth sliding member 40908 is mounted on the fifth linear slide rail 40904. The fifth sliding member 40908 is fixed on the third rod 40903. The sixth linear slide rail 40906 is fixed on the fifth bracket 40907, the sixth sliding member 40905 is installed on the sixth linear slide rail 40906, the sixth sliding member 40905 is fixed on the third rod 40903, and the fifth bracket 40907 is fixed to the third sliding member 40803.

[0142] When the output shaft of the second electric cylinder 41005 extends or retracts, pushing the platform width adjustment component 408 away from or towards the platform frame 41001, the third lever 40903 responds to the platform width adjustment component 408 and reciprocates along the fifth sliding member 40908 on the fifth linear slide rail 40904 (e.g., ...). Figure 30 As shown by arrow d), the second rod 40901 adapts to the width of the carriage.

[0143] When the output shaft of the third electric cylinder 40902 extends or retracts, driving the second rod 40901 to move up and down, the third rod 40903 responds to the second rod 40901 and reciprocates along the sixth sliding member 40905 on the sixth linear slide rail 40906 (e.g., Figure 30 (As indicated by arrow c).

[0144] Specifically, when the third electric cylinder 40902 drives the second rod 40901 to move downward, the second rod 40901 presses the free end of the lever 40604, causing the free end of the lever 40604 to move downward (e.g., Figure 27 (As indicated by arrow a).

[0145] When the third electric cylinder 40902 drives the second rod 40901 to lift upwards, the force on the free end of the lever 40604 disappears, and the tension spring 40603 pulls one end of the fixed baffle 40601 of the lever 40604 downwards, causing the baffle 40601 to reset. The baffle 40601 no longer blocks the box-type material 100, and the second linear push box module 40910 drives the second rod 40901 to push out the rows of box-type materials 100 arranged on the palletizing platform 410 (e.g., Figure 30 (As indicated by arrow e), the stacks are placed inside the carriage.

[0146] Combination Figures 31 to 34When boxed materials 100 in different postures are transferred by the lifting and continuous lifting mechanism 3 to the receiving roller assembly 402 on the lifting and stacking mechanism 4, they are pushed onto the conveying roller assembly 405 by the first linear push box module assembly 403. After the material position adjustment assembly 404 adjusts the position of the boxed materials 100 on the conveying roller assembly 405, they are conveyed forward by the conveying roller assembly 405 to the material blocking assembly 406 arranged on the stacking platform 410 and stop on the chain reciprocating push box assembly 407. The chain reciprocating push box assembly 407 discharges the boxed materials 100 left and right and arranges them into rows. The second linear push box module assembly 409 pushes the arranged boxed materials 100 into the stacking position of the carriage in one go, completing the stacking task of this group of boxed materials 100.

[0147] Combination Figures 31 to 34 When the platform is higher than the carriage floor, when the boxed materials 100 are stacked near the carriage entrance, the receiving roller assembly 402 of the lifting and stacking mechanism 4 may interfere with the platform when stacking the bottom layer of boxed materials 100. This invention uses a linear bearing box unit 40504 fixed on the conveying roller assembly 405 and a guide shaft 41008 fixed on the stacking platform 410. The linear bearing box unit 40504 slides vertically relative to the guide shaft 41008, thereby enabling the conveying roller assembly 405 to rise and fall vertically relative to the stacking platform 410. When the lifting and stacking mechanism 4 is loaded and reaches the vicinity of the platform, the conveying roller assembly 405 rises a certain distance relative to the stacking platform 410 on the guide shaft 41008 (e.g., when the material is loaded onto the guide shaft 41008). Figure 31 As shown in the figure, this avoids the material receiving roller assembly 402 colliding with the platform and solves the loading problem at the car opening.
