[0002] With the development of the corrugated cardboard packaging industry, the demand for higher production speeds from machinery and equipment is also increasing. In traditional cardboard box manufacturing enterprises, due to low production speeds, most bundles of cardboard boxes produced on assembly lines are stacked manually, resulting in low stacking efficiency. Currently, some large enterprises are using robotic arms for stacking, which has improved stacking efficiency.

[0003] However, the existing method of stacking cartons with robotic arms cannot guarantee that the cartons will be stacked neatly, and the stacking quality needs to be further improved. Utility Model Content

The pallet replenishment device supplies pallets for supporting the cartons. The palletizing device includes a lifting and conveying device, a four-sided aligning device, and a lifting device that can drive the lifting and conveying device and the four-sided aligning device to rise and fall respectively. The lifting and conveying device receives the cartons conveyed by the buffer device and conveys the cartons onto the pallets for palletizing. The cartons are located inside the four-sided aligning device, which pushes the cartons to align from all sides. The finished carton output device is used to convey the palletized cartons.

The shifting assembly includes two synchronous wheels rotatably mounted on the second frame, a synchronous belt fitted on the two synchronous wheels, two sliding frames respectively connected to both sides of the synchronous belt, and a drive mechanism five mounted on the second frame and driving one synchronous wheel. The sliding frames are slidably mounted on the second frame, and the clappers are mounted on the sliding frames.

The cartons to be stacked are clamped and lowered by the clamping components in the carton placement device, and then conveyed to the buffer device via a conveyor belt mechanism. Two slapping plates align the cartons from both sides. The conveyor roller mechanism transports the cartons onto the conveyor belt. The bracket is moved upwards and lifts the cartons, conveying them through a pre-reserved channel to the inside of the four-sided alignment device. When the lifting plate is lowered and the bracket is moved in the reverse direction, the bracket can return to its original position, but the cartons on the bracket are blocked by the push plates and fall to the top of the stack. Four push plates push the cartons from all sides inwards, aligning them from the periphery upwards. Attached Figure Description

[0029] like Figures 1-5 As shown in the figure, the gantry palletizer for carton production proposed in this embodiment includes a carton placement device 100, a buffer device 200, a palletizing device, a pallet replenishment device 600, and a finished carton output device 700.

[0030] like Figure 1 and Figure 2 As shown, the carton placement device 100 is used to adjust the placement position of cartons before conveying them. The carton placement device 100 includes a frame 1, a conveyor belt mechanism 2 mounted on the frame 1, two sets of clamping assemblies distributed opposite each other, an adjusting assembly that drives the two sets of clamping assemblies to move towards or away from each other, a rotating assembly that drives the adjusting assembly to rotate, and a displacement assembly that drives the rotating assembly to move laterally. The clamping assembly includes grippers 3, a carriage 4, and a drive mechanism 5. The drive mechanism 5 is mounted on the carriage 4 and drives the grippers 3 to rotate, enabling the grippers 3 to rotate within a 90° range. When a carton needs to be clamped, the two grippers 3 rotate inward; when the carton is placed down, the two grippers 3 unfold outward, and the carton falls onto the conveyor belt mechanism 2 for conveying due to its own weight.

[0031] like Figure 2 As shown, the adjustment assembly includes a guide frame 6, a rotating frame 8, a drive mechanism 81, a gear 9, and two racks 10 distributed on both sides of the gear 9, with the two racks 10 parallel to each other. The drive mechanism 81 is mounted on the rotating frame 8 and driven by the gear 9. The gear 9 meshes with the two racks 10. The racks 10 are mounted on the guide frame 6 and fixedly connected to the slide 4. The slide 4 is slidably mounted on the guide frame 6. The drive mechanism 81 drives the gear 9 to rotate, which in turn drives the two racks 10 to move in opposite directions. The two racks 10, in turn, drive the two slides 4 to move in opposite directions, thereby enabling the two sets of clamping components to move towards or away from each other. This allows for clamping cartons from both sides and is suitable for clamping cartons of different sizes, making it widely applicable.

[0032] like Figure 2 As shown, the rotating assembly includes a translation frame 7 and a second drive mechanism 71 mounted on the translation frame 7. The second drive mechanism 71 is driven to rotate the rotating frame 8, thereby adjusting the orientation of the clamping assembly to adjust the clamped carton to the required orientation. Then, the carton is lowered onto the conveyor belt mechanism 2 via the clamping assembly.

[0033] like Figure 2 As shown, the displacement assembly includes a drive mechanism 11, a gear 12, and a rack 13 horizontally mounted on the frame 1. The drive mechanism 11 is mounted on the translation frame 7 and driven by the gear 12. The gear 12 meshes with the rack 13. The translation frame 7 is slidably mounted on the top of the frame 1. The drive mechanism 11 drives the gear 12 to rotate, the gear 12 moves on the rack 13, and the translation frame 7 slides on the frame 1, thereby achieving position adjustment of the translation frame 7 to grip or lower cartons at different positions using the clamping assembly.

[0034] like Figure 3 As shown, the buffer device 200 receives cartons conveyed by the carton stacking device 100, then pushes the cartons together from both sides and continues conveying. The buffer device 200 includes a second frame 14, a conveyor roller mechanism 15 disposed on the second frame 14, vertically distributed baffles 19, a lifting cylinder disposed on the second frame 14 and driving the baffles 19 to move up and down to move into or out of the rear side of the conveyor roller mechanism 15, two symmetrically distributed clappers 18, and a shifting assembly that drives the two clappers 18 to move towards or away from each other. Before the carton is conveyed to the buffer device 200 by the carton stacking device 100, the two clappers 18 are located in the outer position. The baffles 19 are lifted upward by the lifting cylinder and block the rear side of the buffer device 200. After the carton is conveyed to the conveyor roller mechanism 15, it is blocked by the baffles 19, and then the shifting assembly moves the two clappers 18 towards each other, and the two clappers 18 align the carton from both sides. The shifting assembly includes two synchronous pulleys rotatably mounted on frame 14, a synchronous belt 17 fitted onto the two synchronous pulleys, two sliding frames 171 respectively connected to both sides of the synchronous belt 17, and a drive mechanism 16 mounted on frame 14 and driving one of the synchronous pulleys. The sliding frames 171 are slidably mounted on frame 14, and the clapper 18 is mounted on the sliding frames 171. The drive mechanism 16 can drive one synchronous pulley to rotate, which drives the other synchronous pulley to rotate via the synchronous belt 17. When the synchronous belt 17 rotates, it can drive the two sliding frames 171 to move in opposite directions. The sliding frames 171 slide on frame 14 and drive the clapper 18 to move linearly. The bottom of the clapper 18 has an arc-shaped groove, which is located on the outer periphery of the roller in the conveyor roller mechanism 15, so that the clapper 18 can effectively push the cartons together from both sides. After the cartons are aligned, the lifting cylinder lowers the baffle 19, and the cartons are conveyed to the lifting conveyor device 300 in the palletizing device via the conveyor roller mechanism 15.

[0035] like Figure 4 As shown, the palletizing device includes a lifting and conveying device 300, a four-sided aligning device 400, and a lifting device 500 that can drive the lifting and conveying device 300 and the four-sided aligning device 400 to rise and fall respectively.

[0036] The lifting and conveying device 300 receives the cartons conveyed by the buffer device 200 and transports them to pallets for stacking. The pallet replenishing device 600 supplies pallets to support the cartons. The cartons are gradually stacked on the pallets, with the newly conveyed cartons at the top positioned inside the four-sided aligning device 400, which aligns them from four directions. Before conveying the cartons to the inside of the four-sided aligning device 400, the four-sided aligning device 400 is pre-raised into position by the lifting device 500. The lifting and conveying device 300 includes a lifting frame 22, two rollers 24 rotatably mounted on the lifting frame 22, a drive mechanism 23 mounted on the lifting frame 22 and driving one of the rollers 24 to rotate, multiple conveyor belts 25 mounted side by side on the rollers 24, a slide 29 horizontally slidably mounted on the lifting frame 22, multiple brackets 31 spaced and staggered from the multiple conveyor belts 25, a telescopic mechanism 30 mounted on the slide 29 and driving the brackets 31 to move upward to protrude from the conveyor belts 25 or downward to a height lower than the conveyor belts 25, and a chain drive assembly mounted on the lifting frame 22 and driving the slide 29 to move horizontally. The chain drive assembly includes a drive mechanism 26, a rotating shaft 27, a sprocket 28, and a chain. Two rotating shafts 27 are rotatably mounted on the lifting frame 22. The sprockets 28 are mounted on the rotating shafts 27. The drive mechanism 26 is mounted on the lifting frame 22 and drives one of the rotating shafts 27 to rotate. The chain is meshed and fitted onto the corresponding two sprockets 28. The chain links are connected to the slide 29. When the chain moves, it can drive the slide 29 to slide on the lifting frame 22.

[0037] After the conveyor roller mechanism 15 conveys the carton onto the conveyor belt 25, it continues to be conveyed for a certain distance by the conveyor belt 25 until the carton is completely above the multiple brackets 31. Then, the telescopic mechanism 30 pushes the brackets 31 upward, and the brackets 31 lift the carton on the conveyor belt 25. Then, the chain drive assembly drives the slide 29 to slide horizontally. The slide 29 drives the brackets 31 and the carton on the brackets 31 to move until the carton moves to the inside of the four-sided alignment device 400.

[0038] The four-sided alignment device 400 aligns the cartons from all four sides. The four-sided alignment device 400 includes a lifting plate 34, a cylinder 35, a second lifting frame 36, and four sets of alignment components. Each alignment component includes a push plate 32 and a linear drive mechanism 33 that drives the push plate 32 to move linearly. The four push plates 32 are rectangularly distributed in projection. The linear drive mechanism 33 in one set of alignment components is located on the lifting plate 34, while the linear drive mechanisms 33 in the other three sets of alignment components are located on the second lifting frame 36. The cylinder 35 is located on the first lifting frame 22 and drives the lifting plate 34 to rise and fall. The cylinder 35 raises the lifting plate 34 in advance, making the alignment components on the lifting plate 34 higher than the other three sets of alignment components, leaving a channel below for the support frame 31 and the cartons to move. After the cartons are moved to the inside of the four-sided alignment device 400, the cylinder 35 lowers the lifting plate 34, and the push plate 32 corresponding to the lifting plate 34 blocks the rear of the cartons but does not block the support frame 31. The carton is blocked by the push plate 32 by the chain drive assembly, and thus falls from the bracket 31 to the stacking position. Then, the push plate 32 is driven to move inward by the linear drive mechanism 33 in the four sets of alignment components, and the four push plates 32 align the carton from four directions.

[0039] like Figure 4 As shown, the lifting device 500 includes a gantry frame 20 and lifting mechanisms 211 and 212 mounted on the gantry frame 20. Lifting mechanism 211 drives lifting frame 22 to rise and fall, ensuring that the conveyor belt 25 descends to the height connecting with the conveyor roller mechanism 15 each time, receiving cartons conveyed by the conveyor roller mechanism 15. It also raises lifting frame 22 to the stacking height, moving cartons to the inside of the four-sided alignment device 400 via bracket 31 and placing the cartons on top of the stack. Lifting mechanism 212 drives lifting frame 36 to rise and fall, adjusting the height of the push plate 32, which then aligns the cartons at the top from all sides.

[0040] After the cartons are stacked on the pallet, the finished carton output device 700 is used to transport the stacked cartons.

[0041] This embodiment can align cartons from all sides during stacking, ensuring neatness and high stacking quality. The cartons to be stacked are held by the clamping components in the carton placement device 100. The cartons are adjusted to the target orientation and position using rotation and displacement components, then lowered and conveyed to the buffer device 200 via the conveyor belt mechanism 2. The baffle 19 is raised in advance to block the cartons. After the number of cartons bundled on the conveyor roller mechanism 15 reaches the target, the cartons are aligned from both sides using two clappers 18. The baffle 19 is then lowered, and the cartons are conveyed to the conveyor belt 25 via the conveyor roller mechanism 15, which transports them to a position where they can be effectively supported by the bracket 31. The bracket 31 is then moved upwards to lift the cartons, which are then conveyed through a pre-reserved channel to the inside of the four-sided alignment device 400. The lifting plate 34 is then lowered, and the corresponding push plate 32 blocks the backward movement path of the cartons. When the tray 31 is moved in the reverse direction, the tray 31 can return to its original position, but the cartons on the tray 31 are blocked by the push plate 32 and fall to the top of the stack. The cartons are then aligned from the periphery to the top by the four push plates 32 pushing them inward. Then, the lifting and conveying device 300 and the four-sided alignment device 400 are moved upward by the lifting device 500, and the finished cartons are transported by the finished carton output device 700.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
