Description

Technical Field

[0001] This invention belongs to the field of loading machine technology, specifically relating to a loading machine and a palletizing method for a special type of pallet. Background Technology

[0002] Automated loading machines can automatically load containers and vans, improving loading efficiency and reducing manual labor intensity. An automated loading machine mainly consists of two devices: a conveying device and a loading device. The conveying device receives goods and transports them to the loading device, which then receives the goods and stacks them using its own actions.

[0003] The loading device mainly consists of a traveling chassis, a stacking mechanism, an unloading mechanism, and a lifting mechanism. The traveling chassis is used to drive the entire loading machine to move. The stacking mechanism is used to stack one layer of goods on the loading machine. The unloading mechanism is used to push the stacked goods off the loading machine to complete the stacking of one layer of goods. The lifting mechanism is used to drive the stacking mechanism and the unloading mechanism to rise and fall to complete the stacking of multiple layers of goods.

[0004] However, existing loading machines can usually only stack goods with the front and rear ends of each row aligned during loading. This requires that goods in the same row be stacked horizontally or vertically. However, due to the size of some goods, stacking goods in the same row horizontally or vertically will result in some space left on the sides, which is a waste of space. In order to eliminate or reduce the space left on the sides, it is necessary to stack some goods vertically and some horizontally in the same row. However, existing loading machines cannot stack such a type of goods. Summary of the Invention

[0028] Secondly, embodiments of the present invention provide a special palletizing method based on the above-mentioned special palletizing loading machine, and include the following steps:

[0029] S01, the conveying mechanism sequentially transports two vertical goods to the stacking platform, and the material-pushing mechanism pushes the two vertical goods to both sides of the width direction of the stacking platform respectively;

[0030] S02, several horizontal goods are sequentially transported to the stacking platform, and the horizontal goods are pushed to both sides by the material feeding mechanism to form a row of horizontal materials between two vertical goods;

[0031] S03, move the second pushing surface to the side of the first pushing surface away from the stacking platform, so that the distance between the second pushing surface and the first pushing surface is equal to the difference between the length and width of the goods; then control the second pushing surface and the first pushing surface to move synchronously, pushing the horizontal goods to be flush with the front side of the vertical goods, forming the front row of goods;

[0065] Please refer to the following: Figures 1 to 9 The present invention will now describe the special palletizing loading machine and palletizing method provided by the present invention. The special palletizing loading machine includes a traveling vehicle and a lifting mechanism 20 mounted on the traveling vehicle. The power output end of the lifting mechanism 20 is provided with a first mounting frame 23. It also includes a stacking platform, a conveying mechanism, a material feeding mechanism, and an unloading mechanism. The stacking platform is connected to the first mounting frame 23 and is used to receive goods. The stacking platform has at least two rows of goods stacking positions. The conveying mechanism is connected to the first mounting frame 23 and is used to receive goods and convey them to the stacking platform. The material feeding mechanism is located on the upper side of the stacking platform and is used to push the goods on the stacking platform to both sides. The unloading mechanism has a first pushing surface 55 and two second pushing surfaces 56 that move along the length direction of the traveling vehicle. The two second pushing surfaces 56 are located on both sides of the width direction of the first pushing surface 55, and the second pushing surfaces 56 have a degree of freedom to move relative to the first pushing surface 55 in the length direction of the traveling vehicle.

[0066] Specifically, the lifting mechanism 20 can be a traditional hydraulic cylinder, a lead screw 432 nut, or a chain-type lifting device, etc.

[0067] like Figure 1 and Figure 8As shown, more specifically, in this embodiment, the lifting mechanism 20 comprises a fixed frame 21, an intermediate frame 22, a first mounting frame 23, a primary lifting drive assembly, and a secondary lifting drive assembly. The fixed frame 21 is fixedly connected to the vehicle body. The intermediate frame 22 slides vertically with the fixed frame 21. The first mounting frame 23 is located on the side of the intermediate frame 22 facing away from the fixed frame 21 and slides vertically with the intermediate frame 22. The primary lifting drive assembly includes a primary hydraulic cylinder 24, a primary chain, and a primary movable pulley 25. The primary hydraulic cylinder 24 is connected to the fixed frame 21, with its piston rod end facing upward and connected to the primary movable pulley 25. The primary chain passes around the primary movable pulley 25, with both ends connected to the fixed frame 21 and the intermediate frame 22 respectively, to form a two-fold lifting relationship. The first-stage hydraulic cylinder 24 extends a distance 'a', and the intermediate frame 22 rises a distance '2a'. The second-stage lifting drive assembly includes a second-stage hydraulic cylinder 26, a second-stage chain, a second-stage movable pulley 27, a third-stage chain, and a third-stage movable pulley 28. The third-stage chain passes around the third-stage movable pulley 28, and its two ends are connected to the first mounting frame 23 and the intermediate frame 22, respectively. The second-stage hydraulic cylinder 26 is connected to the intermediate frame 22, and its piston rod end is connected downward to the second-stage movable pulley 27. The second-stage chain passes around the second-stage movable pulley 27, and its two ends are connected to the intermediate frame 22 and the third-stage movable pulley 28, respectively, to form a four-fold lifting relationship, i.e., the second-stage hydraulic cylinder 26 extends a distance 'b', and the first mounting frame 23 rises a distance '4b'. Among them, the first-stage movable pulley 25, the second-stage movable pulley 27, and the third-stage movable pulley 28 are all sprockets.

[0068] The beneficial effects of the special palletizing loading machine provided in this embodiment of the invention are as follows: Compared with the prior art, in the special palletizing loading machine provided in this embodiment of the invention, the pushing direction of the material feeding mechanism is consistent with the width direction of the traveling vehicle, which can accurately push the vertical goods to the preset positions on both sides of the stacking platform. The first pushing surface 55 of the unloading mechanism corresponds to the pushing of the middle horizontal goods, and the two second pushing surfaces 56 correspond to the pushing of the vertical goods on both sides respectively. The degree of freedom of movement of the material feeding mechanism relative to the first pushing surface 55 can be adapted to the length / width difference between the vertical goods and the horizontal goods. That is, by adding a material feeding mechanism and an adjustable spacing pushing surface design, this embodiment of the invention directly solves the technical problem that the existing loading machines cannot stack special pallet types of "vertical on both sides and horizontal in the middle".

[0069] like Figure 2 and Figure 7 As shown, in a specific embodiment of the special palletizing loading machine provided in this invention, the conveying mechanism is slidably connected to the first mounting frame 23 and has the degree of freedom to move along the length of the vehicle body. The end face of the conveying mechanism facing the stacking platform is the first pushing surface 55.

[0070] The unloading mechanism includes an unloading drive assembly 51 and two extended baffle assemblies. The unloading drive assembly 51 is connected to the first mounting frame 23, and its power output end is connected to the conveying mechanism to drive the conveying mechanism to move along the length direction of the vehicle body. The two extended baffle assemblies are respectively located on both sides of the width direction of the conveying mechanism and are connected to the conveying mechanism. The extended baffle assembly includes a pusher and a pusher adjustment drive assembly 54. The end face of the pusher facing the stacking platform is the second pusher surface 56. The pusher adjustment drive assembly 54 is connected to the conveying mechanism, and its power output end is connected to the pusher to drive the pusher to move relative to the conveying mechanism along the length direction of the vehicle body and adjust the distance between the second pusher surface 56 and the first pusher surface 55.

[0071] Specifically, the unloading drive assembly 51 is an electric cylinder, but it can also be a linear drive device such as an electric push rod, a lead screw 432 nut mechanism, or a hydraulic cylinder.

[0072] It should be noted that in this embodiment, the conveying mechanism has the dual functions of "cargo conveying" and "first pushing surface 55", which simplifies the equipment structure. The unloading drive component 51 drives the conveying mechanism to move as a whole, which can realize the first pushing surface 55 pushing the middle horizontal cargo. The pushing adjustment drive component 54 independently drives the pushing parts on both sides to move, and can accurately adjust the position of the second pushing surface 56 according to the size difference between the vertical cargo and the horizontal cargo.

[0073] In this embodiment, through integrated design and independent drive adjustment, flexible and precise control of the spacing between the pushing surfaces is achieved, adapting to the spacing between the front and rear ends of goods with different placement directions in special stacking types, improving stacking accuracy, simplifying the equipment structure, and reducing manufacturing costs.

[0074] like Figure 1 and Figure 2 As shown, in a specific embodiment of the special palletizing loading machine provided in this invention, the stacking platform includes a main platform 61 and an extension platform 62. The extension platform 62 is slidably engaged with the main platform 61 and has the freedom to extend and retract relative to the main platform 61 along the width direction of the traveling vehicle body, thereby adjusting the width of the stacking platform.

[0075] The pusher includes a telescopic rod 52 and a timing plate 53. One end of the telescopic rod 52 is connected to the conveying mechanism, and the other end is connected to the timing plate 53. The timing plate 53 slides with the side of the extension platform 62.

[0076] It should be noted that in this embodiment, the telescopic function of the extension platform 62 can adapt to different widths of carriages or cargo sizes. The arrangement of the synchronization plate 53 makes the second pushing surface 56 form a continuous pushing plane. Its sliding cooperation with the extension platform 62 ensures the stability of the synchronization plate 53 during the pushing process and avoids pushing deviation caused by the adjustment of the width of the stacking platform.

[0077] In this embodiment, the width of the stacking platform can be flexibly adjusted, expanding the equipment's adaptability to different carriage and cargo sizes. The cooperation between the synchronization plate 53 and the extension platform 62 improves the stability of the pushing process, preventing the cargo from tipping over or shifting during the pushing process, and further ensuring the stacking quality.

[0078] like Figure 2 and Figure 3 As shown, in a specific embodiment of the special palletizing loading machine provided in this invention, the material feeding mechanism includes a material feeding body and an adjusting sliding assembly 43. The material feeding body includes a main sliding assembly 41 and a material feeding assembly 42. The main sliding assembly 41 is connected to the traveling vehicle or the conveying mechanism and is provided with a second power output end, which has a degree of freedom to move along the width direction of the traveling vehicle. The material feeding assembly 42 includes a sliding plate 422, which is connected to the second power output end and is used to push the goods under the drive of the main sliding assembly 41. The adjusting sliding assembly 43 is provided with a first power output end connected to the main sliding assembly 41, and the first power output end has a degree of freedom to move along the width direction of the traveling vehicle, which is used to adjust the sliding stroke of the material feeding assembly 42 to match the width of the stacking platform.

[0079] It should be noted that in this embodiment, the main sliding component 41 drives the material-push component 42 to move along the width direction, thereby pushing the goods to form a stack. The adjusting sliding component 43 can drive the main sliding component 41 to move along the width direction, thereby changing the sliding start and end points of the material-push component 42, i.e., adjusting its sliding stroke. When the width of the stacking platform is adjusted by the main platform 61 and the extension platform 62, the adjusting sliding component 43 can correspondingly adjust the stroke of the material-push component 42 to match the width of the stacking platform, ensuring that the material-push component 42 can cover the entire width range of the stacking platform and match different widths of carriages, without needing to replace the main sliding component 41.

[0080] In this embodiment, the stroke of the feeding mechanism is adjustable, enabling it to adapt to stacking platforms of different widths. This ensures that when the width of the stacking platform changes, the feeding component 42 can still accurately push the goods to the preset position to form a regular stack, thus improving the equipment's adaptability to stacking goods of different specifications.

[0081] Specifically, the adjusting sliding assembly 43 includes a fourth mounting bracket 431, a lead screw 432, a first slide 433, and a first drive assembly 434. The two ends of the lead screw 432 are rotatably engaged with the fourth mounting bracket 431. The first slide 433 is sleeved on the lead screw 432 and threadedly engaged with the lead screw 432, and the first slide 433 is the first power output end. The first drive assembly 434 is connected to the fourth mounting bracket 431, and its power output end is connected to the lead screw 432 to drive the lead screw 432 to rotate. The main sliding assembly 41 is slidably engaged with the fourth mounting bracket 431 and fixedly connected to the first slide 433.

[0082] The main sliding assembly 41 includes a second mounting bracket and a second drive assembly 412. The second mounting bracket is slidably engaged with a fourth mounting bracket 431. The second drive assembly 412 is connected to the second mounting bracket and has a second power output end.

[0083] The fourth mounting bracket 431 has two mounting slots 435 spaced apart along the width direction of the loading machine, with the openings of the mounting slots 435 facing downwards. Guide wheels 436 are rotatably connected to the inner sides of the two side walls of the mounting slots 435 along the length direction of the loading machine. The second mounting bracket includes two guide slots 411, which are fixedly connected to the second drive assembly 412 on both sides along the length direction of the loading machine. The guide slots 411 have guide grooves extending along the width direction of the loading machine on their sides, and the guide wheels 436 are engaged within these guide grooves, allowing them to roll freely along the length direction of the guide grooves.

[0084] It should be noted that in this embodiment, the outer peripheral surface of the guide wheel 436 is made of wear-resistant material, the inner wall of the guide groove is smooth, and the clearance between the guide wheel 436 and the guide groove is controlled within a reasonable range to ensure that the guide wheel 436 rolls smoothly without jamming in the guide groove.

[0085] The material feeding assembly 42 includes a third mounting frame 421, a shift plate 422, a connecting plate 423, and a third drive assembly. The third mounting frame 421 is fixedly connected to the second power output end. The upper end of the shift plate 422 is rotatably connected to the third mounting frame 421. The connecting plate 423 is connected to the shift plate 422, and the axis of rotation of the shift plate 422 relative to the third mounting frame 421 is located between the connecting plate 423 and the shift plate 422. The third drive assembly includes a connecting rod 424 and a third drive element 425. One end of the connecting rod 424 is rotatably connected to the connecting plate 423. The third drive element 425 is provided with a third power output end, which has a degree of freedom to move along the width direction of the loading machine. The other end of the connecting rod 424 is rotatably connected to the third power output end, which is used to drive the shift plate 422 to switch between a horizontal state and a vertical state.

[0086] It should be noted that the lever 422 achieves switching between horizontal and vertical states through a rotating connection. In the horizontal state, it avoids interfering with the transport of goods, while in the vertical state, it is used to push goods for placement. The third drive component provides power support for the switching action.

[0087] The state switching design of the lever 422 avoids interference with the cargo transportation process and improves the smoothness of the operation process; the vertical lever 422 can provide stable thrust to ensure that the cargo is placed neatly.

[0088] Furthermore, the rotation structure of the lever 422 is optimized by the connecting plate 423, and the state switching of the lever 422 is achieved by the transmission method of the connecting rod 424. The third driving element 425 drives the third power output end to move, and drives the connecting plate 423 to rotate through the connecting rod 424, forming a crank-connecting rod 424 transmission mechanism, thereby controlling the lever 422 to switch between horizontal and vertical states.

[0089] The crank-connecting rod 424 transmission structure is stable and can provide sufficient power for the switching of the paddle 422, ensuring reliable operation. On the other hand, the setting of the connecting plate 423 optimizes the force transmission path and reduces stress concentration at the connection of the paddle 422. In addition, the transmission process is smooth, avoiding impact when the paddle 422 is switched, thus protecting goods and equipment.

[0090] The third drive element 425 is the second electric cylinder, which has a third slide table, which is the third power output end. The connecting rod 424 is rotatably connected to the third slide table. The second electric cylinder can also be replaced by a hydraulic cylinder, an electric actuator, a servo motor, a stepper motor, etc.

[0091] like Figure 1 and Figure 3 As shown, in a specific embodiment of the special palletizing loading machine provided in this invention, a material feeding adjustment drive assembly 44 is also included. The material feeding mechanism is slidably engaged with the conveying mechanism. The material feeding adjustment drive assembly 44 is connected to the conveying mechanism, and the power output end is connected to the material feeding mechanism to drive the material feeding mechanism to move along the length direction of the traveling vehicle.

[0092] Specifically, the material feeding adjustment drive assembly 44 is a hydraulic cylinder, but it can also be replaced by an electric actuator, electric cylinder, etc. The fourth mounting bracket 431 on the material feeding mechanism slides in conjunction with the frames on both sides of the conveying mechanism in the width direction.

[0093] It should be noted that in this embodiment, the material feeding adjustment drive assembly 44 drives the material feeding mechanism to move along the length direction, which can change the front and rear position of the shift plate 422 relative to the conveying mechanism and the goods. When the length of the goods is different, the shift plate 422 is adjusted to be located in the middle position of the goods. At this time, the pushing force of the shift plate 422 on the goods is more uniform, which can avoid the goods tilting or shifting due to the bias of the pushing force.

[0094] In this embodiment, the position of the material feeding mechanism along the length direction is adjustable, ensuring that the feeding plate 422 acts on the middle of the goods, so that the goods are balanced by force, reducing the displacement or tilting of the goods during the feeding process, ensuring the regularity of the stacking pattern on the stacking platform, and further improving the stacking quality.

[0095] like Figure 1 and Figure 4As shown, in a specific embodiment of the special palletizing loading machine provided in this invention, the conveying mechanism includes a front conveying component 31, a lifting frame 32, a transverse frame 33, a rear conveying component 34, and a lifting drive component 35. The front conveying component 31 is horizontally slidably connected to the first mounting frame 23, and one end face is a pushing surface. The lifting frame 32 is slidably connected to the traveling vehicle body and has the freedom to move up and down. The transverse frame 33 is slidably connected to the lifting frame 32 and has the freedom to move horizontally along the lifting frame 32. One end of the rear conveying component 34 is rotatably connected to the end of the front conveying component 31 facing away from the stacking platform, and the other end is rotatably connected to the transverse frame 33. The lifting drive component 35 is connected to the traveling vehicle body, and its power output end is connected to the lifting frame 32 to drive the lifting frame 32 to move up and down.

[0096] The unloading drive assembly 51 drives the front conveying assembly 31 and the rear conveying assembly 34 to move horizontally synchronously to transport the material to a designated position on the stacking platform or to perform unloading operations. The lifting drive assembly 35 drives the feed end of the rear conveying assembly 34 to move up and down to adjust the slope of the rear conveying assembly 34 and prevent the material from sliding due to excessive slope.

[0097] Specifically, the front conveyor assembly 31 and the rear conveyor assembly 34 are both belt conveyor equipment, and the lifting drive assembly 35 is a linear drive device such as a hydraulic cylinder, electric actuator, or electric cylinder.

[0098] like Figure 1 and Figure 5 As shown, in a specific embodiment of the special palletizing loading machine provided in this invention, the traveling vehicle body includes a traveling chassis 11, a mobile frame 12, and a frame drive assembly 13. The mobile frame 12 is slidably engaged with the traveling chassis 11 and has the freedom to move along the length direction of the traveling chassis 11. The frame drive assembly 13 is connected to the traveling chassis 11, and its power output end is connected to the mobile frame 12 to drive the mobile frame 12 to move. The lifting mechanism 20 is fixedly connected to the mobile frame 12.

[0099] Specifically, the frame drive assembly 13 is a hydraulic cylinder, but it can also be a linear drive device such as an electric actuator, a lead screw 432 nut mechanism, etc. Before unloading, the moving frame 12 is in the extended state. During unloading, the moving frame 12 drives the stacking platform, conveying mechanism, and unloading mechanism to retreat synchronously. At the same time, the unloading mechanism controls the first pushing surface 55 and the second pushing surface 56 to move forward, so that the first pushing surface 55 and the second pushing surface 56 move forward and remain stationary relative to the carriage, thereby allowing the goods stacked in the preset stack shape to fall in place, ensuring the integrity of the stack shape. "Falling in place" means that after the goods form the preset stack shape on the stacking platform, they will not slide relative to the carriage along the length of the moving vehicle body during the unloading process. Instead, as the stacking platform retreats, they maintain their position relative to the carriage under the obstruction of the first stacking surface and the second pushing surface 56, and finally fall directly to the target position inside the carriage after the stacking platform is removed.

[0100] It should be noted that in this embodiment, the chassis 11 provides basic support for the entire device, the mobile frame 12 can slide relative to the chassis 11 along its length, and the frame drive assembly 13 provides power for the movement of the mobile frame 12. Since the lifting mechanism 20 is fixedly connected to the mobile frame 12, the movement of the mobile frame 12 can drive the lifting mechanism 20, the stacking platform, and other components to move synchronously, realizing the retraction of the stacking platform and providing conditions for the goods to fall in place.

[0101] In this embodiment, the traveling vehicle body achieves the retraction of the stacking platform by sliding the mobile frame 12. Its structure is simple and the movement is stable. It can accurately control the retraction speed and distance of the stacking platform, ensure precise coordination with the movement of the pushing surface, ensure the reliability of the goods falling in place, and improve the overall stability of the equipment movement.

[0102] like Figure 5 and Figure 7 As shown, in a specific embodiment of the special palletizing loading machine provided in this invention, the traveling vehicle body also includes a support wheel 14. The support wheel 14 is located at one end of the mobile frame 12 facing the stacking platform and is connected to the mobile frame 12 to support the mobile frame 12.

[0103] It should be noted that in this embodiment, the support wheel 14 is located at one end of the mobile frame 12 near the stacking platform. When the mobile frame 12 slides out relative to the chassis 11, the support wheel 14 contacts the ground, providing support for the end of the mobile frame 12 and preventing the mobile frame 12 from bending or deforming due to the weight of the stacking platform and the goods.

[0104] In this embodiment, the support wheel 14 enhances the structural stability of the mobile frame 12 in the extended state, prevents the mobile frame 12 from being damaged due to excessive force, ensures the structural reliability of the equipment during the unloading process, and avoids the displacement of the stacking platform caused by the deformation of the mobile frame 12, further ensuring the accuracy of the goods falling in place.

[0105] like Figure 9 As shown, based on the same inventive concept, this embodiment of the invention also provides a special palletizing method, based on the above-mentioned special palletizing loading machine, and includes the following steps:

[0106] S01, the conveying mechanism sequentially transports two vertical goods to the stacking platform, and the material-pushing mechanism pushes the two vertical goods to both sides of the width direction of the stacking platform respectively;

[0107] S02, several horizontal goods are sequentially transported to the stacking platform, and the horizontal goods are pushed to both sides by the material feeding mechanism to form a row of horizontal materials between two vertical goods;

[0108] S03, move the second pushing surface 56 to the side of the first pushing surface 55 away from the stacking platform, so that the distance between the second pushing surface 56 and the first pushing surface 55 is equal to the difference between the length and width of the goods; then control the second pushing surface 56 and the first pushing surface 55 to move synchronously, push the horizontal goods to be flush with the front side of the vertical goods, forming the front row of goods.

[0109] S04, continue to transport several horizontal goods to the stacking platform in sequence, and push the horizontal goods to both sides through the material feeding mechanism to form a rear row of horizontal materials between two vertical goods;

[0110] S05, control the distance between the first pushing surface 55 and the second pushing surface 56 so that it is the same as the difference between the rear side of the vertical goods and the rear horizontal goods, and then move forward synchronously to push the two rows of goods off the stacking platform to complete the stacking of one layer of goods.

[0111] S06, the lifting mechanism 20 drives the stacking platform, conveying mechanism, material feeding mechanism and unloading mechanism to move upward layer by layer, and completes the stacking of multiple layers of goods in sequence.

[0112] The beneficial effects of the special stacking method provided in this embodiment of the invention are as follows: Compared with the prior art, in the special stacking method provided in this embodiment of the invention, steps S01-S02 clearly define the order of goods placement as "vertical on both sides and horizontal in the middle". Steps S03 and S05 ensure that the front and rear ends of goods in different placement directions are aligned by adjusting the spacing of the pushing surfaces. Step S06 realizes multi-layer stacking through the lifting mechanism 20. Each step corresponds one-to-one with the structural features of the loading machine, forming a complete operation process. This solves the problem that the existing methods cannot adapt to this stacking type, while improving stacking efficiency and space utilization, and reducing the need for manual intervention.

[0113] like Figure 1 and Figure 2 As shown, in a specific embodiment of the special palletizing method provided in this invention, in step S05, the traveling vehicle moves the palletizing platform backward, and the first pushing surface 55 and the second pushing surface 56 move forward at the same speed. The pushing surface is stationary relative to the carriage, so that the goods on the palletizing platform fall in place.

[0114] It should be noted that in this embodiment, the backward movement of the traveling vehicle and the forward movement of the pushing surface form a reverse synchronous action. The stationary state of the pushing surface relative to the carriage can prevent the goods from having additional horizontal displacement during the pushing process, ensuring that the goods fall vertically to the preset stacking position.

[0115] In this embodiment, the design of reverse synchronous motion further improves the positional accuracy of cargo stacking, prevents cargo from shifting or tipping over during the falling process, ensures the stability of multi-layer stacking, and reduces the risk of cargo damage.

[0116] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
