Description

Technical Field

[0001] This invention relates to the field of tablet packaging technology, and in particular to a fully automated tablet packaging production line. Background Technology

[0002] A tablet packaging production line is a specialized piece of equipment designed for packaging various tablet products. This equipment is widely used in the pharmaceutical, health supplement, and food processing industries, enabling precise tablet counting and efficient packaging to meet the demands of large-scale production.

[0003] Traditional tablet packaging relies heavily on manual labor or semi-automatic equipment, lacking integrated automated production lines that connect tablets to individual pouches and then to bulk bags. For example, current tablet packaging machines can only form individual small packages of tablets; subsequent pouch counting, bulk bag packaging, and packaging quality inspection require additional equipment. This process often necessitates significant manual intervention, leading to inefficiency and inconsistent packaging quality. Furthermore, existing pouch forming methods often involve cutting and separating the packaging, which can damage the packaging and hinders precise coordination with subsequent processes. The overall production process suffers from low automation and cumbersome connections, failing to meet the demands of large-scale, high-efficiency production.

[0004] Therefore, there is an urgent need to design a fully automated tablet packaging production line that can achieve a fully automated process from tablets to small pouches and then to finished bulk packaging, significantly reducing manual intervention, greatly improving production efficiency, reducing human error, and ensuring stable and reliable packaging quality. At the same time, it can effectively overcome the limitations of traditional cutter-separation technology, reducing the risk of packaging damage; the entire process can achieve a high degree of automation and collaboration, ensuring both production efficiency and packaging quality, and effectively meeting the needs of large-scale, high-precision, and high-efficiency tablet packaging production.

[0035] Traditional tablet packaging relies heavily on manual labor or semi-automatic equipment, lacking integrated automated production lines that connect tablets to individual pouches and then to bulk bags. For example, current tablet packaging machines can only form individual small packages of tablets; subsequent pouch counting, bulk bag packaging, and packaging quality inspection require additional equipment. This process often necessitates significant manual intervention, leading to inefficiency and inconsistent packaging quality. Furthermore, existing pouch forming methods often involve cutting and separating the packaging, which can damage the packaging and hinders precise coordination with subsequent processes. The overall production process suffers from low automation and cumbersome connections, failing to meet the demands of large-scale, high-efficiency production.

[0036] To address the aforementioned issues, this application provides a fully automated tablet packaging production line. This line enables a fully automated process from tablets to small pouches and then to finished bulk packaging, significantly reducing manual intervention, improving production efficiency, minimizing human error, and ensuring stable and reliable packaging quality. Simultaneously, it effectively overcomes the limitations of traditional cutter-separation technology, reducing the risk of packaging damage. The entire process achieves a high degree of automation and collaboration, ensuring both production efficiency and packaging quality, effectively meeting the demands of large-scale, high-precision, and high-efficiency tablet packaging production.

[0037] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0038] Example

[0039] Please see Figures 1-11The fully automated tablet packaging production line of this application includes a small bag packaging mechanism 1, a small bag picking mechanism 2, a small bag conveying mechanism 3, a counting mechanism 4, a material collection conveying mechanism 5, a large bag conveying mechanism 6, a transition buffer mechanism 7, a large bag visual inspection mechanism 8, and a labeling mechanism 9. The small bag packaging mechanism 1 is used to accurately fill and seal tablet materials into small packaging bags. The small bag picking mechanism 2 is located at the lower end of the small bag packaging mechanism 1 and is used to pick up the small bag materials sealed by the small bag packaging mechanism 1 and transfer them to the small bag conveying mechanism 3. The small bag conveying mechanism 3 is located beside the small bag picking mechanism 2. The counting mechanism 4 is located at the end of the small bag conveying mechanism 3 and is used to count and collect the small bag materials conveyed by the small bag conveying mechanism 3. The material collection conveying mechanism 5 is located between the counting mechanism 4 and the large bag conveying mechanism 6, and the conveying direction of the material collection conveying mechanism 5 is perpendicular to the conveying direction of the small bag conveying mechanism 3. The transition buffer mechanism 7, the large bag visual inspection mechanism 8, and the labeling mechanism 9 are sequentially located on one side of the large bag conveying mechanism 6 and are used to buffer the large packaging bags, check the quality of the large bags, and affix labels to the large packaging bags, respectively.

[0040] Specifically, the small bag packaging mechanism 1 includes a frame 11, N vibrating counting hoppers 12, a bag feeding section, and a bag sealing section. The N vibrating counting hoppers 12 are located at the top of the frame 11 and are used to vibrate the tablet material to the bag feeding section according to a preset quantity. That is, each vibrating counting hopper 12 accurately counts the tablet material through vibration and then conveys it to the bag feeding section. The bag feeding section is located below the N vibrating counting hoppers 12 and is used to provide small packaging bags corresponding one-to-one with the vibrating counting hoppers 12, and to align the empty small packaging bags with the discharge ports of the vibrating counting hoppers 12 to receive the tablet material from the vibrating counting hoppers 12. The sealing section is located below the bag supply section and is used to seal the small bags containing tablets, and to process the edges of the small bags into a serrated connection structure; that is, when a specified amount of tablet material is put into the small packaging bag, the sealing section quickly seals the small packaging bag to ensure that the tablet material is sealed inside the small bag, completing the initial process of small bag packaging, and providing qualified small bag material for subsequent processes such as small bag taking, conveying, and counting.

[0041] The bag-taking mechanism 2 includes a swing motor 21, a swing link 22, a connecting block 23, a flipping motor 24, a flipping link 25, a suction cup guide rod 26, N suction cup mounting parts 27, and N suction cups 28. The swing motor 21 is mounted on the frame 11 of the bag packaging mechanism 1, and the output shaft of the swing motor 21 extends outward for easy connection to the swing link 22. One end of the swing link 22 is fixedly connected to the output shaft of the swing motor 21, and the other end is fixedly connected to the connecting block 23, so that the swing motor 21 can drive the swing link 22 to swing. For example, the swing link 22 includes a first link 221 and a second link 222. The bottom end of the first link 221 is connected to the output shaft of the swing motor 21, and the top end is connected to one end of the second link 222. The second link 222 is horizontally arranged, and the other end of the second link 222 is connected to the connecting block 23. The flipping motor 24 is disposed on the outside of the connecting block 23. The flipping connecting rod 25 rotatably passes through the top end of the connecting block 23 and is fixedly connected to the output shaft of the flipping motor 24. The suction cup guide rod 26 is disposed parallel to one side of the flipping connecting rod 25 and is fixedly connected to the flipping connecting rod 25 through a mounting block, thereby enabling the flipping motor 24 to drive the flipping connecting rod 25 and the suction cup guide rod 26 to flip. N suction cup mounting parts 27 are sleeved on the suction cup guide rod 26, and N suction cups 28 are disposed parallel to the N suction cup mounting parts 27 and are connected to a vacuum pump for sucking up and separating the small bag material sealed by the small bag packaging mechanism 1. When picking up small bag materials, the swing motor 21 operates, driving the flip motor 24, the suction cup guide rod 26, the suction cup mounting part 27, and the suction cup 28 to reciprocate through the swing connecting rod 22 and the connecting block 23, so that the suction cup 28 can be aligned with the small bag materials and pick up the small bag materials; then the flip motor 24 operates, driving the suction cup guide rod 26 to flip through the flip connecting rod 25, so that the suction cup 28 can reach above the small bag conveying mechanism 3, so that the picked-up small bag materials can be placed on the small bag conveying mechanism 3.

[0042] Furthermore, the bag-picking mechanism 2 also includes a variable-pitch cylinder and several variable-pitch connecting rods 29. The variable-pitch cylinder is located on one side of the suction cup mounting part 27. One end of each of the several variable-pitch connecting rods 29 is fixedly connected to the piston rod of the variable-pitch cylinder, and the other end is hinged to N suction cup mounting parts 27 respectively, for adjusting the spacing between the N suction cups 28 to accommodate the suction needs of small bags of different sizes. When it is necessary to adjust the spacing between the N suction cups 28 to accommodate small bags of different sizes, the variable-pitch cylinder operates, its piston rod extends or retracts, and through the several variable-pitch connecting rods 29, drives the N suction cup mounting parts 27 to slide on the suction cup guide rod 26, thereby changing the spacing between the N suction cups 28. This allows the bag-picking mechanism 2 to flexibly pick up small bags of different sizes, improving the applicability and versatility of the equipment.

[0043] The small bag conveying mechanism 3 includes a drive assembly, a chain track, and a conveyor chain 31. The drive assembly is located at one end of the chain track and provides conveying power to the conveyor chain 31, enabling it to move cyclically on the chain track. The chain track is arranged in a ring shape, providing a stable running path for the conveyor chain 31. Specifically, the drive assembly includes a conveyor motor, a drive sprocket, a driven sprocket, and a conveyor chain. The conveyor motor is fixed at one end of the chain track, and its output shaft is fixedly connected to the drive sprocket. The driven sprocket is located at the other end of the conveyor chain track. The conveyor chain is wound around the drive sprocket and the driven sprocket and is fixedly connected to the conveyor chain 31. When the conveyor motor is working, the transmission action of the drive sprocket, the conveyor chain, and the driven sprocket drives the conveyor chain 31 to move cyclically on the chain track, realizing the continuous conveying of small bag materials.

[0044] The conveyor chain plate 31 is laid on the chain track, with a flat surface and certain strength, used to carry and convey small bag materials to a designated position. Specifically, the conveyor chain plate 31 includes a base plate 311, M baffles 312, and several partitions 313. The base plate 311 is connected to the chain track, providing a stable bearing surface for the small bag materials. The M baffles 312 are arranged parallel and perpendicularly on the base plate 311, dividing the base plate 311 into N columns, and the extending direction of the M baffles 312 is consistent with the conveying direction of the base plate 311, wherein M=N+1, to prevent the small bag materials from slipping off the sides during conveying. The several partitions 313 are arranged parallel and perpendicularly on the base plate. On 311, and located between two adjacent baffles 312, it works in conjunction with the baffles 312 to divide the bottom plate 311 into multiple independent small bag placement stations. Each small bag placement station can hold a small bag of material, and the small bag placement stations are distributed in a matrix to ensure that the small bag materials are arranged in an orderly manner during the conveying process, avoiding mutual collision or stacking. Thus, when the drive component is started, it drives the conveyor chain plate 31 to move in a direction on the chain plate track, accurately conveying the small bag materials placed on it by the small bag picking mechanism 2 to the counting mechanism 4.

[0045] The counting mechanism 4 includes a first hopper 41, a second hopper 42, a third hopper 43, a first cylinder, a second cylinder, and a third cylinder. The first hopper 41, the second hopper 42, and the third hopper 43 are arranged sequentially from top to bottom to receive and temporarily store small bag materials conveyed from the small bag conveying mechanism 3. The volumes of the first hopper 41, the second hopper 42, and the third hopper 43 increase sequentially. For example, several first hoppers 41, second hoppers 42, and third hoppers 43 are provided. Any first hopper 41 can hold 9 small bags of material, any second hopper 42 can hold 9, 18, or 27 small bags of material, and any third hopper 43 can hold 9, 18, 27, 36, or 56 small bags of material. The first cylinder is disposed on one side of the first hopper 41 and connected to the hopper door of the first hopper 41, and is used to open or close the hopper door of the first hopper 41; the second cylinder is disposed on one side of the second hopper 42 and connected to the hopper door of the second hopper 42, and is used to open or close the hopper door of the second hopper 42. The third cylinder is disposed on one side of the third hopper 43 and connected to the hopper door of the third hopper 43, and is used to open or close the hopper door of the third hopper 43; wherein, the hopper doors are respectively disposed at the bottom ends of the first hopper 41, the second hopper 42, and the third hopper 43. When it is necessary to collect and count the small bags of material, the small bags of material first enter the first hopper 41. After a predetermined number of small bags of material have accumulated in the first hopper 41, the first cylinder is activated to open the hopper door of the first hopper 41, and the small bags of material enter the second hopper 42. After a predetermined number of small bags of material have accumulated in the second hopper 42, the second cylinder is activated to open the hopper door of the second hopper 42, and the small bags of material enter the third hopper 43. After a predetermined number of small bags of material have accumulated in the third hopper 43, the hopper door of the third hopper 43 is opened, allowing the small bags of material to fall onto the material collection and conveying mechanism 5.

[0046] Furthermore, the distance between any two adjacent first bins 41 is A; the distance between any two adjacent second bins 42 is B; the distance between any two adjacent third bins 43 is C; where A < B < C, such that the bins are reasonably distributed in space, which not only ensures sufficient space to accommodate different quantities of small bag materials, but also facilitates the subsequent orderly collection and transfer of the small bag materials. Even further, the counting mechanism 4 further includes a counting sensor and a controller. The counting sensor is disposed on one side of the first bin 41, the second bin 42, and the third bin 43, and is configured to detect the quantity of the passing small bag materials and send the detection signal to the controller. The controller receives the detection signal sent by the counting sensor and controls the actions of the first cylinder, the second cylinder, and the third cylinder according to the feedback information, so as to achieve accurate counting and material conveying control. It should be noted that when unqualified small bag materials are detected, N small bag materials in a row can be removed through the rejection conveyor line. This specific structure is prior art and will not be elaborated herein.

[0047] The material collection and conveying mechanism 5 includes a conveyor frame 51, a servo motor 52, a transmission chain 53, and a receiving box 54. The conveyor frame 51 includes a first horizontal section, a climbing section, and a second horizontal section arranged sequentially, providing a stable support structure for the entire material collection and conveying mechanism 5 and ensuring the stability of the equipment during operation. The first horizontal section is lower than the counting mechanism 4 and is used to receive small bags of material falling from the counting mechanism 4. The climbing section is located between the first and second horizontal sections, meaning the second horizontal section is higher than the first horizontal section, facilitating subsequent loading of larger packaging bags. The servo motor 52 is located on one side of the conveyor frame 51 and provides precise driving force to the transmission chain 53. It has high-precision speed and position control capabilities, enabling precise adjustment of the transmission chain 53's running speed and stopping position according to production needs. The transmission chain 53 is mounted on the conveyor frame 51 and is connected to the output end of the servo motor 52 via a sprocket assembly, thereby achieving power transmission. The receiving box 54 is fixed to the transmission chain 53 and moves with the transmission chain 53 to receive the counted small bags of material falling from the third hopper 43. Specifically, the receiving box 54 includes a box body 541, a fixing block 542, and screws 543. The box body 541 is generally rectangular and hollow inside to accommodate the small bags of material. Its size is designed according to the maximum stacking volume of the largest number of small bags of material that may occur in actual production, ensuring sufficient storage space. The fixing block 542 is fixed to the bottom end of the box body 541, and the fixing block 542 has screw holes at both ends near the transmission chain 53. The screws 543 pass through the transmission chain 53 and are threaded into the screw holes, thereby fixing the box body 541 to the transmission chain 53 and ensuring that the receiving box 54 will not loosen or fall off during the movement of the transmission chain 53. There is a gap of 0.03-0.1mm between the screw 543 and the transmission chain 53 to ensure that the screw 543 can rotate flexibly in the transmission chain 53. When the hopper door of the third hopper 43 is opened, the small bag of material falls into the receiving box 54. The receiving box 54 is driven by the transmission chain 53 to move along the first horizontal section of the conveyor frame 51. When it reaches the climbing section, it rises smoothly under the drive of the transmission chain 53 and finally reaches the second horizontal section for the subsequent large bag packaging process.

[0048] The labeling mechanism 9 is used to print product labels and affix them to the large packaging bags. After the large packaging bags pass through the labeling mechanism 9, the mechanism peels the product labels from the label paper and pastes them onto the large packaging bags, completing the labeling process. The bags are then conveyed to the large bag vision inspection mechanism 8. When the large packaging bags arrive at the vision inspection mechanism 8, if any defects are detected, such as loose product labels, misalignment, or printing errors, the vision inspection mechanism 8 will immediately send a signal to the control system. The control system will then remove the defective products from the production line, effectively improving the overall product quality and production efficiency. Once the large packaging bags pass the inspection by the vision inspection mechanism 8, they enter the transition buffer mechanism 7.

[0049] The transition buffer mechanism 7 includes a buffer motor 71, a synchronous pulley 72, a synchronous belt 73, a swing pulley 74, a swing arm 75, a swing shaft 76, a suction cup rod 77, a large bag suction cup 78, and a buffer plate. The synchronous pulley 72 is sleeved on the output shaft of the buffer motor 71 and is fixedly connected to the output shaft; the two ends of the synchronous belt 73 are respectively sleeved on the synchronous pulley 72 and the swing pulley 74, and rotate with the rotation of the synchronous pulley 72; one end of the swing shaft 76 is fixedly connected to the swing pulley 74, and the other end passes through the arc-shaped groove 751 of the swing arm 75 and extends outward; the suction cup rod 77 is fixed on the other end of the swing shaft 76 and swings together with the swing shaft 76; the bottom end of the suction cup rod 77 is provided with multiple large bag suction cups 78, and the openings of the large bag suction cups 78 face downward, for sucking up large packaging bags. The buffer tray is positioned below the large bag suction cup 78, and its surface is flat. It is used to temporarily hold the large packaging bags picked up by the large bag suction cup 78. When the large packaging bag is conveyed from the large bag visual inspection mechanism 8, the buffer motor 71 is started. Through the transmission of the synchronous pulley 72, the synchronous belt 73, and the swing wheel 74, the swing arm 75 drives the suction cup rod 77 to swing. The large bag suction cup 78 picks up the large packaging bag and places it on the buffer tray, realizing the transition buffering of the large packaging bag and avoiding production stagnation or chaos caused by the mismatch of the speed of the preceding and following processes. When it is necessary to transfer the large packaging bag to the large bag conveying mechanism 6, the buffer motor 71 is started again. Through the transmission of the synchronous pulley 72, the synchronous belt 73, and the swing wheel 74, the swing arm 75 drives the suction cup rod 77 to swing. The large bag suction cup 78 picks up the large packaging bag on the buffer tray again and accurately places it on the large bag conveying mechanism 6.

[0050] The large bag conveying mechanism 6 provides large packaging bags and fills the small bags of material transferred from the material collection conveying mechanism 5 into the large bags, then seals them. The large bag conveying mechanism 6 also includes a barcode and visual inspection mechanism 61 for detecting the barcodes on the large packaging bags. This mechanism 61 is located at the rear end of the large bag conveying mechanism 6 and performs comprehensive inspection of the appearance of the large packaging bags. It can accurately identify defects such as damage, stains, and wrinkles on the surface of the packaging bags, as well as issues such as whether the barcode is properly affixed and accurately positioned. Once a large packaging bag that does not meet quality standards is detected, the system immediately issues an alarm signal and feeds the relevant information back to the control system. The control system then marks the non-conforming large packaging bag and removes it from the production line in subsequent processes to prevent it from entering the later packaging stages. This ensures that every large packaging bag entering the packaging process meets quality requirements, effectively improving the overall product quality and the stability of the production process.

[0051] It should be noted that the structures not elaborated above are all existing technologies, including but not limited to the specific structures of the large bag conveying mechanism 6, the large bag visual inspection mechanism 8, and the labeling mechanism 9. These are all reasonably designed by those skilled in the art based on existing technologies to achieve the corresponding functions, and will not be described in detail in this application.

[0052] Working principle:

[0053] When tablet materials need to be packaged, the small bag packaging mechanism 1 starts working, sealing the tablet materials in a small packaging bag. Then, the swing motor 21 of the small bag picking mechanism 2 starts, driving the suction cup mounting part 27 and the suction cup 28 to swing back and forth, accurately aligning with the small bag material and picking it up. Subsequently, the flipping motor 24 works, driving the suction cup guide rod 26 to flip through the flipping connecting rod 25, so that the suction cup 28 reaches above the small bag conveying mechanism 3, placing the picked-up small bag material on the small bag placement station on the conveyor chain plate 31. The conveying motor of the drive component of the small bag conveying mechanism 3 then starts, driving the conveyor chain plate 31 to move cyclically on the chain plate track, continuously conveying the small bag material to the counting mechanism 4. The counting sensor of the counting mechanism 4 detects the number of small bags of material passing through and sends a signal to the controller. When a predetermined number of small bags of material accumulate in the first hopper 41, the controller controls the first cylinder to open the hopper door of the first hopper 41, and the small bags of material enter the second hopper 42. Similarly, when the predetermined number of small bags of material accumulates in the second hopper 42 and the third hopper 43, the second cylinder and the third cylinder control the hopper doors to open, allowing the small bags of material to fall into the receiving box 54 of the collecting and conveying mechanism 5. The servo motor 52 of the collecting and conveying mechanism 5 starts, and drives the receiving box 54 to move along the conveyor frame 51 through the transmission chain 53. It first passes through the first horizontal section, then rises smoothly to the climbing section, and finally reaches the second horizontal section, preparing for subsequent falling into the large bag conveying mechanism 6. Simultaneously, the labeling mechanism 9 peels the product label from the label paper and affixes it to the large packaging bag, completing the labeling process. Then, the large bag visual inspection mechanism 8 inspects the appearance and barcode of the large packaging bag. If a defective product is found, an alarm signal is immediately issued, and the control system marks and removes it from the production line. If the inspection is qualified, the buffer motor 71 of the transition buffer mechanism 7 is activated, driving the large bag suction cup 78 to pick up the large packaging bag and place it on the buffer tray, realizing transition buffering and avoiding production stagnation or chaos. When needed, it is accurately placed on the large bag conveying mechanism 6. The large bag conveying mechanism 6 provides large packaging bags. When the material collection conveying mechanism 5 transfers the small bag material, it is filled into the large bag packaging and sealed to form the finished product and output. Finally, the barcode and visual inspection mechanism 61 identifies whether there are defects in the finished product. If the inspection is unqualified, the product is rejected; if the inspection is qualified, it is conveyed to the next process, thus completing the fully automatic packaging production process of tablet materials from small bag packaging to large bag packaging.

[0054] In this embodiment, the fully automated tablet packaging production line of this application includes a small bag packaging mechanism, a small bag picking mechanism, a small bag conveying mechanism, a counting mechanism, a material collection conveying mechanism, a large bag conveying mechanism, a transition buffer mechanism, a large bag visual inspection mechanism, and a labeling mechanism. By setting up the small bag picking mechanism, the separation, picking, and placement of small bag materials can be completed accurately and efficiently, effectively solving the packaging damage problem easily caused by the use of a cutter in the prior art, as well as the difficulty in achieving precise coordination with subsequent processes. By setting up the small bag conveying mechanism, it is ensured that the small bag materials remain orderly arranged during the conveying process, effectively avoiding mutual collisions or stacking, allowing the small bag materials to arrive at the counting mechanism stably and regularly, facilitating subsequent counting. By setting up the transition buffer mechanism, the problem of speed mismatch between preceding and following processes is effectively solved, avoiding production stagnation or chaos, making the entire production process smoother and more efficient. Through the collaborative operation of multiple units, a series of automated production processes have been achieved, from precise material picking, orderly conveying, and accurate counting from tablets to small pouches, to the loading of small pouch materials into large pouches, inspection of the appearance and barcode of large pouches, product labeling, and transition buffering of large packaging bags. This has greatly reduced manual intervention, significantly improved production efficiency, reduced human error, and ensured stable and reliable packaging quality.
