Abstract
Description
Technical Field
[0001] This utility model relates to the field of palletizing and loading machine technology, and in particular to a palletizing and loading machine. Background Technology
[0002] In modern logistics and industrial production processes, cargo palletizing and loading are crucial steps, with their efficiency and quality directly impacting production costs and transportation safety. Five-layer palletizing, as a highly efficient and stable method, is widely used across numerous industries. By arranging goods in staggered layers, five-layer palletizing effectively enhances the stability of the pallet structure, significantly reducing the risk of goods collapsing or shifting due to vibration and bumps during transportation, thus substantially reducing cargo damage. Simultaneously, this method makes fuller use of truck cargo space, increasing transport capacity and thereby reducing unit transportation costs. In the building materials industry, five-layer palletizing ensures the safety of bagged cement and aggregates during long-distance transportation; in the food industry, this method prevents damage and spoilage of bagged flour and condiments during transport.
[0003] While existing palletizing devices can improve efficiency to some extent, they also have serious shortcomings. Firstly, when using rake-like robotic arms to pick up bagged products, the unloading height is relatively high, and the material falls into the truck bed in a free-fall manner. Due to the large drop at the bottom of the truck bed, the bagged products generate significant dust upon landing, and they are prone to shifting, resulting in uneven stacking. Secondly, the suction cup method for picking up bagged products also has problems. Suction cups typically adhere to the middle of the bag. For fully filled bags, this helps maintain a roughly straight shape after suction. However, for partially filled bags (i.e., bags with less material), the ends tend to sag. If these bags are directly loaded and stacked sequentially, unstable stacking is highly likely, leading to pallet collapse. Utility Model Content
[0004] The main purpose of this invention is to propose a palletizing and loading machine that can adapt to transport vehicles of different heights while improving palletizing quality.
[0005] It improves the accuracy of bagged material palletizing and enhances the stability of bagged product palletizing.
[0006] To achieve the above objectives, the palletizing and loading machine proposed in this utility model includes:
[0007] Guide rails are used to fix the equipment in the factory building, and a vehicle passage is formed below the guide rails for transport vehicles to enter.
[0008] The machine body includes a walking frame, a movable frame, and a first drive unit. The walking frame is slidably mounted on the guide rail, and the movable frame is located below the first drive unit. The first drive unit is connected between the walking frame and the movable frame and is used to drive the movable frame to rise and fall relative to the walking frame.
[0009] A palletizing device includes a palletizing gate, a mounting frame, a lifting bracket, and a second drive unit. The mounting frame is slidably mounted on a movable frame, and the sliding direction of the mounting frame is perpendicular to the sliding direction of the movable frame on a horizontal plane. The lifting bracket is movably mounted on the mounting frame via the second drive unit. The palletizing gate is rotatably mounted on the lower end of the lifting bracket, and the rotation axis of the palletizing gate extends vertically. The second drive unit drives the lifting bracket to move vertically relative to the mounting frame, thereby causing the palletizing gate to move up and down.
[0010] A conveying device, installed on the mounting frame and with the conveying direction pointing towards the palletizing gate, is used to convey materials to the palletizing gate;
[0011] By horizontally sliding the walking frame, horizontally sliding the mounting frame, vertically raising and lowering the movable frame and the palletizing gate, and horizontally rotating the palletizing gate, the material can be palletized and positioned in three-dimensional space.
[0012] Optionally, the top of the movable frame is provided with a plurality of first guide posts extending in a vertical direction, and the traveling frame is provided with a plurality of first guide sleeves corresponding to the first guide posts. Each first guide sleeve is slidably sleeved on the first guide post to form a guide structure for the lifting and lowering of the movable frame.
[0013] Optionally, the first drive unit includes an electric hoist, which is mounted on the traveling frame and its traction end is connected to the movable frame to drive the movable frame to lift and lower.
[0014] Optionally, the conveying device includes a belt conveyor, the conveying direction of which is directed toward the palletizing gate, and the discharge end of the belt conveyor is higher than the top support surface of the palletizing gate.
[0015] Optionally, the second drive unit includes a lifting motor, a lifting gear, and a lifting rack. The lifting motor is mounted on the mounting frame and its output shaft is connected to the lifting gear. The lifting rack is vertically fixed to the lifting bracket and meshes with the lifting gear, so that the lifting motor drives the lifting gear to rotate, thereby causing the lifting bracket to move up and down in the vertical direction.
[0016] Optionally, the lifting bracket includes at least two second guide columns extending in a vertical direction, and a connecting plate connected to the lower ends of the two second guide columns. The mounting bracket is provided with a plurality of second guide sleeves corresponding to the second guide columns, and each second guide sleeve is slidably sleeved on the second guide column. The stacking gate is rotatably installed at the lower end of the connecting plate.
[0017] Optionally, the palletizing gate is connected to the connecting plate via a rotary drive mechanism. The rotary drive mechanism includes a rotary motor fixed to the connecting plate. The output shaft of the rotary motor extends downward and is fixedly connected to the palletizing gate for driving the palletizing gate to rotate around a vertical axis.
[0018] Optionally, the palletizing gate includes a main body, a drive mechanism, and two hinges. The main body is rotatably mounted on the lower end of the lifting bracket, and the two hinges are hinged to the main body. The drive mechanism is used to drive the two hinges to rotate synchronously to form a closed state for supporting materials or an open state for releasing materials.
[0019] Optionally, the driving mechanism includes a driving component, a single slider, and two sets of crank-connecting rods. The single slider is slidably mounted on the main body. The two sets of crank-connecting rods are spaced apart on both sides of the single slider, each corresponding to one of the hinges. The crank and the connecting rod of each set are hinged together. The crank is connected to the hinge, and the connecting rod is connected to the single slider. The driving component is mounted on the main body and is used to drive the single slider to slide up and down, while the two sets of crank-connecting rods drive the hinge to rotate.
[0020] Optionally, the palletizing device further includes a third drive unit, which includes a translation motor, a translation gear, and a translation rack. The translation motor is mounted on the mounting frame and its output shaft is connected to the translation gear. The translation rack is horizontally fixed to the movable frame and meshes with the translation gear so that the translation motor drives the translation gear to rotate, thereby causing the mounting frame to translate relative to the movable frame.
[0021] This utility model's technical solution utilizes the horizontal sliding of the traveling frame and mounting frame, combined with the vertical movement of the movable frame and palletizing gate, to achieve precise X / Y / Z three-axis positioning, covering any coordinate point within the carriage. Simultaneously, the horizontal rotation of the palletizing gate allows for adjustment of the material placement angle, perfectly adapting to the angle switching requirements of multi-layered cross-stacking in complex palletizing (e.g., the first layer horizontal, the second layer vertical), ensuring strict alignment of each layer of material and improving palletizing stability.
[0022] In addition, the overall lifting of the mobile frame can achieve a wide range of height adjustments to adapt to the height of different vehicle bodies. The partial lifting of the palletizing gate is used to slowly lower the material when approaching the palletizing layer, which can prevent the material from colliding or tipping over due to excessive height difference, thus improving the palletizing quality. Moreover, it can prevent excessive dust when palletizing materials such as flour and cement.
[0023] Moreover, the guide rails are fixed above the factory building, and vehicles pass through the passage below, forming a three-dimensional operation layout. This avoids the problem of traditional ground equipment occupying ground space and can operate in parallel with ground conveyor lines, forklifts and other equipment, improving the utilization rate of factory space.

[0037] This utility model proposes a palletizing and loading machine.
[0038] In the embodiments of this utility model, such as Figures 1 to 7 As shown, the palletizing and loading machine includes a guide rail, a body 400, a palletizing device 300, and a conveying device 200. The guide rail is used to fix the machine to the factory building, and a vehicle passage is formed below the guide rail for transport vehicles to enter. The body 400 includes a traveling frame 410, a movable frame 420, and a first drive unit 430. The traveling frame 410 is slidably mounted on the guide rail, and the movable frame 420 is located below the first drive unit 430. The first drive unit 430 is connected between the traveling frame 410 and the movable frame 420 and is used to drive the movable frame 420 to rise and fall relative to the traveling frame 410. The palletizing device 300 includes a palletizing gate 310, a mounting frame 320, a lifting bracket 330, and a second drive unit 340. The mounting frame 320 is slidably mounted on the movable frame 420, and the sliding direction of the mounting frame 320 is the same as the sliding direction of the traveling frame 410. The directions are perpendicular to each other on the horizontal plane. The lifting bracket 330 is movably mounted on the mounting frame 320 via the second drive unit 340. The palletizing gate 310 is rotatably mounted on the lower end of the lifting bracket 330, and the rotation axis of the palletizing gate 310 extends vertically. The second drive unit 340 is used to drive the lifting bracket 330 to rise and fall relative to the mounting frame 320 in the vertical direction, thereby driving the palletizing gate 310 to rise and fall. The conveying device 200 is mounted on the mounting frame 320, and the conveying direction is pointed towards the palletizing gate 310, used to convey materials to the palletizing gate 310. Through the horizontal sliding of the traveling frame 410, the horizontal sliding of the mounting frame 320, the vertical lifting and falling of the movable frame 420 and the palletizing gate 310, and the horizontal rotation of the palletizing gate 310, the palletizing and positioning of materials in three-dimensional space is realized.
[0039] Specifically, the transport vehicle enters the factory and stops in the vehicle aisle below the guide rail, and the vehicle body position must be aligned with the working range of the palletizing and loading machine. Then, the traveling frame 410 slides along the guide rail to the initial position directly above the vehicle. The movable frame 420 is lowered to the preset height through the first drive unit 430. The palletizing gate 310 is raised to the highest position through the second drive unit 340 and the lifting bracket 330. The gate is in a closed state, forming a material support surface. At the same time, it rotates to the initial angle to support the material conveyed by the conveying device 200.
[0040] After the palletizing gate 310 moves the material to above the preset palletizing position, the palletizing gate 310 will open to release the material and drop it to the designated palletizing position. In this way, through the horizontal sliding of the traveling frame 410, the horizontal sliding of the mounting frame 320, the vertical lifting of the movable frame 420 and the palletizing gate 310, and the horizontal rotation of the palletizing gate 310, the material can be accurately delivered from the conveying end to any position in the carriage. This is especially suitable for multi-layered, cross-stacking palletizing scenarios.
[0041] This utility model's technical solution utilizes the horizontal sliding of the traveling frame 410 and mounting frame 320, combined with the vertical movement of the movable frame 420 and the palletizing gate 310, to achieve precise X / Y / Z three-axis positioning, covering any coordinate point within the carriage. Simultaneously, the horizontal rotation of the palletizing gate 310 allows for adjustment of the material placement angle, perfectly adapting to the angle switching requirements of multi-layered cross-stacking in multi-layered palletizing (e.g., the first layer horizontal, the second layer vertical), ensuring strict alignment of each layer of material and improving palletizing stability.
[0042] In addition, the overall lifting of the movable frame 420 can achieve a wide range of height adjustments to adapt to the height of different vehicle carriages. The partial lifting of the palletizing gate 310 is used to slowly lower the material when approaching the palletizing layer, which can prevent the material from colliding or tipping over due to excessive height difference, thus improving the palletizing quality. Moreover, it can prevent excessive dust when palletizing materials such as flour and cement.
[0043] Moreover, the guide rails are fixed above the factory building, and vehicles pass through the passage below, forming a three-dimensional operation layout. This avoids the problem of traditional ground equipment occupying ground space and can operate in parallel with ground conveyor lines, forklifts and other equipment, improving the utilization rate of factory space.
[0044] In some embodiments, the top of the movable frame 420 is provided with a plurality of first guide posts 421 extending in a vertical direction, and the traveling frame 410 is provided with a plurality of first guide sleeves 411 corresponding to the first guide posts 421. Each first guide sleeve 411 is slidably sleeved on the first guide post 421 to form a guide structure for the lifting and lowering of the movable frame 420. Specifically, the movable frame 420 achieves vertical lifting and lowering through the first drive unit 430, and the sliding cooperation between the guide post and the guide sleeve provides it with strict vertical guidance. Through the rigid connection between the guide sleeve and the traveling frame 410, the lateral offset or rotational sway that may occur during the lifting and lowering of the movable frame 420 can be effectively constrained, ensuring the positioning accuracy of the palletizing device 300 and avoiding the offset of the material placement position caused by the tilt of the movable frame 420.
[0045] In some embodiments, the first drive unit 430 includes an electric hoist 431, which is mounted on the traveling frame 410. The traction end of the electric hoist 431 is connected to the movable frame 420 to drive the movable frame 420 to lift and lower. Specifically, the movable frame 420 of the palletizer needs to bear the static weight of the palletizing device 300 and the dynamic load of materials. The rated lifting capacity of the electric hoist 431 can easily cover such load requirements, and its lifting speed is significantly higher than that of traditional hydraulic cylinders or screw drives, allowing for rapid adjustment of the movable frame 420's height over a wide range. Moreover, the main body of the electric hoist 431 can be directly mounted on the top or side of the traveling frame 410 without occupying additional space under the traveling frame 410, leaving more room for the lifting stroke of the movable frame 420.
[0046] In some embodiments, the conveying device 200 includes a belt conveyor 210, the conveying direction of which is directed toward the palletizing gate 310, and the discharge end of the belt conveyor 210 is higher than the top support surface of the palletizing gate 310. Specifically, since the discharge end of the belt conveyor 210 is higher than the support surface of the palletizing gate 310, the material itself is discharged from a high position to a low position by gravity, forming a natural sliding process. Compared with a structure that uses a handling robot for conveying, the belt conveyor 210 has higher conveying efficiency, lower cost, and is easier to maintain.
[0047] In some embodiments, the second drive unit 340 includes a lifting motor 341, a lifting gear 342, and a lifting rack 343. The lifting motor 341 is mounted on the mounting bracket 320, and its output shaft is connected to the lifting gear 342. The lifting rack 343 is vertically fixed to the lifting bracket 330 and meshes with the lifting gear 342, so that the lifting motor 341 drives the lifting gear 342 to rotate, thereby driving the lifting bracket 330 to rise and fall vertically. Specifically, the gear and rack transmission is a rigid meshing transmission with a constant transmission ratio and no slippage, which can achieve high-precision vertical lifting of the palletizing gate 310, ensuring the positioning accuracy of materials when palletizing at different heights. Compared with flexible transmissions such as wire ropes and chains, the gear and rack transmission has stronger vibration and impact resistance, and is especially suitable for frequent start-stop and heavy-load scenarios, avoiding gate swaying caused by transmission gaps or elastic deformation, and ensuring the stability of material support and release. Moreover, by converting rotary motion into linear motion through a rack and pinion, the transmission efficiency is high and the energy loss is low. When combined with a servo motor or frequency converter, stepless adjustment of lifting speed and precise feedback control of position can be achieved, thereby adapting to the needs of different material weights and palletizing rhythms and further improving loading efficiency.
[0048] In some embodiments, the lifting bracket 330 includes at least two second guide posts 331 extending vertically, and a connecting plate 332 connected to the lower ends of the two second guide posts 331. The mounting bracket 320 is provided with a plurality of second guide sleeves corresponding to the second guide posts 331, and each second guide sleeve is slidably sleeved on the second guide post 331. The palletizing gate 310 is rotatably mounted on the lower end of the connecting plate 332. Specifically, the second guide posts 331 extend vertically and slide in cooperation with the second guide sleeves, providing rigid guiding constraints for the lifting movement of the palletizing gate 310, ensuring that it moves strictly along the vertical trajectory, avoiding tilting or swaying caused by lateral forces, thereby avoiding the risk of material misplacement or tipping due to gate tilt, and further improving palletizing accuracy.
[0049] In some embodiments, the palletizing gate 310 is connected to the connecting plate 332 via a rotary drive mechanism 312. The rotary drive mechanism 312 includes a rotary motor 360 fixed to the connecting plate 332. The output shaft of the rotary motor 360 extends downward and is fixedly connected to the palletizing gate 310, for driving the palletizing gate 310 to rotate around a vertical axis. Specifically, multi-layered palletizing requires materials to be stacked in a cross-stacking manner. By driving the palletizing gate 310 to rotate via the rotary motor 360, the material can change direction during delivery, easily achieving a cross-stacking pattern such as a first layer of horizontal stacking and a second layer of vertical stacking, meeting specific palletizing requirements, improving the stability of the pallet and space utilization. Moreover, the rotary motor 360 has a fast start and stop speed, enabling it to complete the rotation of the palletizing gate 310 in a short time, reducing the time interval of palletizing operations and improving overall palletizing efficiency.
[0050] In some embodiments, the palletizing gate 310 includes a main body 311, a drive mechanism 312, and two hinges 313. The main body 311 is rotatably mounted on the lower end of the lifting bracket 330, and the two hinges 313 are hinged to the main body 311. The drive mechanism 312 drives the two hinges 313 to rotate synchronously to form a closed state for supporting materials or an open state for releasing materials. Specifically, when the two hinges 313 are in the closed state, they together form a flat supporting surface, which can stably support materials conveyed from the conveying device 200. Whether it is a regular-shaped box, bagged goods, or irregularly shaped items, they can remain stable on this supporting surface, reducing the risk of shaking, slipping, or tipping of materials during the receiving process, and ensuring that the materials are safely received by the palletizing gate 310. Moreover, the drive mechanism 312 can drive the two hinges 313 to rotate synchronously, realizing rapid opening and accurately releasing materials to the designated palletizing position. During the palletizing process, this rapid-response release action can reduce the time that materials stay in the air and improve palletizing efficiency. Meanwhile, by precisely controlling the opening angle and speed of the hinge 313, it can be ensured that the materials fall along the predetermined trajectory, achieving accurate delivery and guaranteeing the neatness and stability of the palletizing.
[0051] In some embodiments, the drive mechanism 312 includes a drive member 3121, a single slider 3122, and two sets of crank-connecting rods 3123. The single slider 3122 is slidably mounted on the main body 311. The two sets of crank-connecting rods 3123 are spaced apart on both sides of the single slider 3122, each corresponding to a hinge 313. The crank and connecting rod of each set are hinged, with the crank connected to the hinge 313 and the connecting rod connected to the single slider 3122. The drive member 3121 is mounted on the main body 311 and is used to drive the single slider 3122 to slide up and down, while the two sets of crank-connecting rods 3123 drive the hinge 313 to rotate. Specifically, the two sets of crank-connecting rods 3123 are symmetrically distributed on both sides of the single slider 3122. When the drive member 3121 drives the slider to slide up and down, the connecting rods on both sides synchronously drive the two hinges 313 to rotate via the cranks. This design, with a single power source driving dual-sided actuators, mechanically ensures that the rotation angles and speeds of the two hinges 313 are completely identical, thus completely avoiding the asynchronous opening and closing problems caused by control errors or component wear in traditional dual-drive systems (such as two independent cylinders). Furthermore, the crank-connecting rod 3123 mechanism is a rigid transmission; when converting the linear motion of the slider into the rotational motion of the hinges 313, compared to flexible transmissions such as belts and chains, there is no elastic deformation during the transmission process, and the hinge point between the connecting rod and the crank can withstand a larger load.
[0052] In some implementations, the drive component 3121 is a motor, and the drive mechanism 312 also includes a lead screw 3124, which is screwed to the single slider 3122 and connected to the output shaft of the motor. Specifically, the lead screw 3124 transmission is a continuous meshing transmission. Compared with the pneumatic impact of the cylinder or the rigid push of the electric push rod, the movement speed and acceleration of the slider can be steplessly adjusted when the motor drives the lead screw 3124, realizing smooth start-stop and uniform speed movement. This avoids the problems of insufficient precision, large impact and low safety of the traditional drive component 3121 in the opening and closing action of the palletizing gate 310, and is especially suitable for heavy-duty palletizing scenarios with high requirements for control precision and safety.
[0053] In some embodiments, there are two palletizing devices 300. The two palletizing devices 300 are installed on the movable frame 420 via the same palletizing track. The two palletizing devices 300 can slide independently via the track. The conveying device 200 feeds materials to the two palletizing devices in sequence. When one palletizing device is palletizing, the conveying device 200 can directly feed materials to the other palletizing device 300 without waiting for the previous palletizing device 300 to complete its work cycle, thereby improving the palletizing efficiency of the palletizing and loading machine.
[0054] In some embodiments, the palletizing device 300 further includes a third drive unit 350, which includes a translation motor 351, a translation gear 352, and a translation rack 353. The translation motor 351 is mounted on the mounting frame 320, and its output shaft is connected to the translation gear 352. The translation rack 353 is horizontally fixed to the movable frame 420 and meshes with the translation gear 352, so that the translation motor 351 drives the translation gear 352 to rotate, thereby causing the mounting frame 320 to translate relative to the movable frame 420. Specifically, the gear and rack transmission is a rigid meshing transmission with a constant transmission ratio and no slippage, which can achieve high-precision lateral movement of the palletizing gate 310, ensuring the positioning accuracy of the material. Compared with flexible transmissions such as wire ropes and chains, the gear and rack transmission has stronger vibration and impact resistance, and is especially suitable for frequent start-stop and heavy-load scenarios, avoiding gate swaying caused by transmission gaps or elastic deformation, and ensuring the stability of material support and release. Moreover, by converting rotary motion into linear motion through a rack and pinion, the transmission efficiency is high and the energy loss is low. When combined with a servo motor or frequency converter, stepless adjustment of lifting speed and precise feedback control of position can be achieved, thereby adapting to the needs of different material weights and palletizing rhythms and further improving loading efficiency.
