For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0032] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0033] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a palletizing and conveying system of the utility model in conjunction with the accompanying drawings.

[0034] like Figure 1As shown, a palletizing conveying system of the utility model has a core component of a palletizing machine 1, which is specifically responsible for the splitting and conveying of pallets 14. Within the framework of the palletizing machine 1, the pallet 14 is accurately forked and stacked by a forklift 3 configured on one side. The system also integrates an empty pallet double-chain conveyor 11 for empty pallets 14, which is installed at one end of the palletizing machine 1 to continuously supply pallets 14. In addition, in order to achieve efficient steering and transmission of pallets 14, multiple groups of composite transplanters 12 arranged side by side are introduced into the design. These devices can effectively perform right-angle steering and conveying functions. In the interval area of ​​multiple groups of composite transplanters 12, a six-axis robot 4 is deployed. The role of the six-axis robot 4 is to perform the grabbing and stacking tasks of the box, thereby improving the entire palletizing process. In short, this system optimizes the automated process from pallet 14 processing to final palletizing by finely coordinating the various components. It is particularly worth mentioning that the palletizing conveying system shows significant beneficial effects when handling special goods such as liquid dyes. Liquid dyes are prone to overflow and have extremely high requirements for packaging integrity, which places higher demands on the stability and accuracy of the conveying system. This system greatly reduces vibration and tilt during transportation through the high-precision grasping and stacking operations of the six-axis robot 4 and the smooth steering ability of the composite transplanter 12, effectively avoiding the leakage and contamination of liquid dyes.

[0035] When the palletizing process is completed, the output end of the composite transplanter 12 is equipped with a palletizing position conveyor 5 and a full pallet three-chain conveyor 6, which work together to ensure that the palletized goods can be smoothly and continuously transported to the next process. Furthermore, on one side of the full pallet three-chain conveyor 6, a fork-picking position conveyor 7 designed specifically for forking is provided. In this way, once the fully loaded pallet arrives at the preset forking area, the forklift 3 can immediately intervene and efficiently remove these pallets 14 from the conveying system, thereby completing the seamless connection process from palletizing to output. The six-axis robot 4, the palletizing position conveyor 5 and the full pallet three-chain conveyor 6 can be enclosed by the fence 2.

[0036] like Figure 2-Figure 4 As shown, the core structure of the pallet supply crane 1 involves a pallet warehouse 13, and a lifting platform 18 is provided below the storage area to realize the vertical movement of the pallet 14. The pallet warehouse 13 is used as a storage area for the pallet 14, and the pallet 14 can be easily loaded and unloaded by the forklift 3. It is worth noting that the pallet warehouse 13 adopts a three-sided support frame structure design, which enhances its stability and storage safety.

[0037] On one side of the pallet warehouse 13, there is a loading entrance 134, which is specially equipped with a positioning baffle 133 to accurately guide and fix the position of the pallet 14, ensuring that the pallet 14 can be accurately aligned during storage or retrieval, thereby improving the efficiency and accuracy of the operation. This series of carefully designed structures jointly promotes the efficient operation and space optimization of the pallet 14 management of the stacker 1.

[0038] The two sides of the pallet warehouse 13 are also equipped with relatively arranged latches 135, which can be turned over by the cylinder 136 installed above, realizing delicate control. The specific operation process is: when the lifting platform 18 is raised to the highest position, the latch 135 immediately starts the working mode. As the lifting platform 18 is lowered to the middle position, the pallet 14 originally located at the bottom is carried away from the pallet warehouse 13 by the platform. At this moment, the latch 135 responds quickly and accurately limits the pallet 14 originally on the second layer to prevent it from sliding down. Subsequently, the lifting platform 18 continues to descend to the lowest point. At this time, the pallet 14 that has been accurately separated is smoothly transferred to the entrance of the empty pallet double-chain conveyor 11 with the help of the conveying equipment 16 below, ready to enter the next processing flow. This design greatly improves the automation level and operating efficiency of the sorting and transportation of pallets 14.

[0039] The conveying device 16 is disposed below the tray 14 , and can achieve a conveying effect when the lifting platform 18 descends to the lower position.

[0040] Rotating frames 131 are arranged opposite to each other on both sides of the top opening of the pallet warehouse 13, and a rotatable forward and reverse threaded rod 132 is arranged between the two opposite rotating frames 131, and a worm wheel 138 arranged in the middle of the forward and reverse threaded rod 132 can rotate with it. A worm 151 that can drive the rotation of the worm wheel 138 is meshed above the worm wheel 138, and the rotation of the worm 151 is driven by the motor 15. As the motor 15 runs, the worm 151 arranged at the conveying end can drive the worm wheel 138 together, and the forward and reverse threaded rod 132 can rotate together after the worm wheel 138 rotates.

[0041] The two sides of the outer circumference of the positive and negative threaded rod 132 are respectively threadedly connected with the limit clamp 17, the end of which extends to the area between the two latch teeth 135, and a limit rod 137 is arranged below the opposite position of the positive and negative threaded rod 132, one end of which passes through the limit hole 171 opened on one side of the outer surface of the limit clamp 17. Therefore, after the pallet 14 is placed inside the pallet warehouse 13, the motor 15 can be operated at this time, and after the motor 15 is operated, the positive and negative threaded rod 132 can be rotated together, and after the positive and negative threaded rod 132 rotates, the limit clamps 17 on both sides can be displaced toward each other, and then the two limit clamps 17 can clamp the middle pallet 14, and then the alignment effect is achieved.

[0042] like Figure 4-Figure 7 As shown, at the bottom of the end of the limit clamp 17, there are hinged rotatable rotation shafts 173, and the rotation shafts 173 are two arranged on the same horizontal line, and one end of the rotation shaft 173 extends to the inside of a rotation hole 177 opened upward at the bottom of the limit clamp 17, so that the rotation shaft 173 can rotate.

[0043] A worm gear 174 is provided at the top of one of the rotating shafts 173, and a worm 176 is meshed on one side of the worm gear 174 to drive the worm 176 to rotate. The rotation of the worm 176 is driven by a motor 175, and a rotating belt 172 is sleeved on the outer circumference of the two rotating shafts 173. When the two limit clamps 17 move toward each other and clamp, the surface of the rotating belt 172 can contact the surface of the tray 14, and then the worm 176 is driven by the motor 175. After the worm 176 is operated, the rotating shaft 173 can be rotated. As the rotating shaft 173 rotates, the rotating belt 172 can cause multiple groups of stacked trays 14 to move toward the baffle 133, so that the stacked trays 14 can be neatly stacked and placed so that they are misaligned with each other.

[0044] Working principle of a palletizing conveying system: At the beginning of the process, empty pallets 14 are continuously supplied to one side through the empty pallet double-chain conveyor 11 to ensure uninterrupted supply of pallets 14. The composite transplanter 12 is arranged and arranged to be responsible for the right-angle steering conveying of the pallets 14 to improve logistics efficiency. The six-axis robot 4 accurately performs the grabbing and stacking operations to further improve the palletizing process. The completed pallets are smoothly transported to the next process via the palletizing position conveyor 5 and the full pallet three-chain conveyor 6, while the fork position conveyor 7 ensures that the forklift 3 can efficiently remove the full pallet 14 and achieve rapid output.

[0045] In the operation of the pallet warehouse 13, the up and down movement of the lifting platform 18 cooperates with the precise positioning and limiting function of the latching teeth 135 to ensure the orderly access and stable transportation of the pallets 14. In particular, the latching teeth 135 controlled by the cylinder 136 can accurately lock the pallet 14 to prevent the lower pallet 14 from sliding down, and the conveying device 16 is started when the lifting platform 18 descends to transport the pallet 14 to the next process.

[0046] The design of the top rotating frame 131 and the forward and reverse threaded rods 132 drives the rotation of the worm 151 and the worm wheel 138 through the motor 15, driving the limit clamp 17 to move toward each other, thereby achieving accurate alignment of the tray 14. In addition, the combination of the rotating shaft 173, the worm wheel 174 and the worm 176 at the bottom of the limit clamp 17 is driven by the motor 175, and contacts the surface of the tray 14 through the rotating belt 172, so that the trays 14 are neatly stacked to avoid misalignment.

[0047] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
