Description

Technical Field

[0001] This invention relates to the field of pharmaceutical packaging box transfer technology, specifically to a pharmaceutical packaging box transfer system and its control method. Background Technology

[0002] Drug packaging box transportation is a key process in the drug production and distribution chain. It refers to the safe and efficient transfer and distribution of finished drug packaging boxes between various workstations in the workshop, warehouses and production areas, and between pharmaceutical companies and distributors, using specialized transportation equipment.

[0003] Currently, traditional pharmaceutical packaging box transportation relies heavily on manual sorting or single conveying equipment, lacking automated non-conforming product screening functions. Inadequately packaged or poorly sealed non-conforming products are easily mixed into qualified batches and flow into subsequent stages, leading to quality risks. To address this, we propose a pharmaceutical packaging box transportation system and its control method. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pharmaceutical packaging box transfer system and its control method. This system solves the problem that existing pharmaceutical packaging box transfer systems rely heavily on manual sorting or single conveying equipment, lack automated non-conforming product screening functions, and are prone to mixing into qualified batches with improperly packaged or incompletely sealed non-conforming products, leading to quality risks in subsequent processes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A pharmaceutical packaging box transfer system includes support legs with a frame mounted on the upper end of each leg. The frame houses a conveying assembly for transferring pharmaceutical packaging boxes. Above the frame is a removal assembly for screening defective pharmaceutical packaging boxes. The removal assembly includes a support rod fixedly connected to the upper surface of the frame. A carrier plate is fixedly connected to the upper end of the support rod. Two symmetrically arranged sliding holes are formed on the upper surface of the carrier plate, and a slide frame is slidably connected within these holes. A push plate for removing defective pharmaceutical packaging boxes is fixedly connected to the lower end of the slide frame. The movement trajectory of the push plate is perpendicular to the movement trajectory of the conveying assembly. A positioning plate is fixedly connected to one side of the carrier plate, and a camera is fixedly connected to the lower surface of the positioning plate. Utilizing real-time image recognition technology from the camera, the system accurately captures defective products such as improperly packaged or incompletely sealed items. Combined with the mechanical pushing of the push plate and the airflow assistance of the fan blades, a dual force is formed to ensure that defective products quickly leave the main conveyor line. The bidirectional screening design can be adapted to conveying slides on both sides, eliminating the need for frequent equipment adjustments, effectively improving screening efficiency and reducing the risk of defective products flowing into subsequent stages.

[0006] As a further preferred embodiment of the present invention, a positioning seat is fixedly connected to one side of the carrier plate, and a drive motor is installed inside the positioning seat. A protrusion is fixedly connected to the upper surface of the slide, and the protrusion is cylindrical. A swing arm is fixedly connected to the drive end of the drive motor. A guide hole is opened on the upper surface of the swing arm, and the protrusion is located inside the guide hole. When the swing arm rotates, it drives the slide and push plate to move through the protrusion. The system integrates the drug packaging box transfer and non-conforming product screening functions, eliminating the need for additional independent screening equipment. The roller conveyor assembly continuously transfers while completing real-time detection and diversion, reducing production link connections and shortening the overall production cycle. Non-conforming products fall directly into the discharge assembly through the conveying chute, achieving centralized transfer, avoiding material accumulation, and optimizing production site management.

[0007] As a further preferred embodiment of the present invention, a positioning rod is fixedly connected to the upper surface of the slide, and a magnetic plate is fixedly connected to one end of the positioning rod. Two symmetrically arranged limiting blocks are fixedly connected to the upper surface of the carrier plate. A magnet is installed on one side of the limiting block, and the magnet and the magnetic plate are magnetically attracted to each other to limit the slide when it is at both ends of the sliding hole. The sliding cooperation between the slide and the sliding hole, and the attraction and positioning between the magnet and the magnetic plate, ensure that the push plate movement is accurate and stable, and reduce mechanical wear. The forward and reverse rotation design of the fan blades can flexibly adapt to the screening needs on both sides. The roller conveyor assembly supports the transfer of medicine packaging boxes of different sizes and specifications. The structure of the material conveying slide and the discharge assembly can be adjusted according to the layout of the production site, adapting to large-scale production lines and small processing scenarios, and has strong versatility.

[0008] As a further preferred embodiment of the present invention, two L-shaped top rods are fixedly connected to the side of the carrier plate near the positioning plate, and a cover plate is fixedly connected to the upper end of the top rods. The cover plate above the camera can effectively block external interference light, improve the clarity and accuracy of image recognition, and avoid misjudgment caused by changes in light. The linkage control of the drive motor and servo motor responds quickly, can accurately lock the position of unqualified products and complete the push, and has high screening accuracy, further ensuring the overall quality of drug packaging.

[0009] As a further preferred embodiment of the present invention, both sides of the frame are fixedly connected to conveying slides, and the upper surface of the conveying slides is fixedly connected to baffles for guiding the unqualified drug packaging boxes pushed by the pusher plate into the conveying slides. From material transfer, image recognition, bidirectional pushing, to centralized transfer of unqualified products, no manual intervention is required throughout the entire process, only periodic checks of the equipment's operating status are needed. The camera detection accuracy is not affected by human fatigue, and the screening consistency is strong. Compared with the traditional manual screening mode, it can significantly reduce manpower input and reduce the quality risks and management costs caused by human error.

[0010] As a further preferred embodiment of the present invention, a bracket is fixedly connected to the inner wall of the push plate, a servo motor is installed inside the bracket, and a fan blade is fixedly connected to the output end of the servo motor. Mounting slots are provided on both sides of the push plate, and protective nets are installed in the mounting slots. During the pushing process, the airflow generated by the fan blades can buffer the impact of mechanical pushing, preventing defective products from deforming due to collision. The buffer plate of the discharge assembly, in conjunction with the spring, can effectively absorb the impact of defective products falling, preventing damage to the packaging boxes. This is especially suitable for pharmaceutical packaging boxes with brittle materials or fragile packaging, ensuring the feasibility of subsequent material processing.

[0011] In a further preferred embodiment of the present invention, the conveying assembly includes rollers, which are rotatably connected to the inner wall of the frame. There are multiple rollers arranged at equal intervals. A shaft on one side of each roller passes through the frame and is fixedly connected to a driven wheel. A control motor is fixedly connected to one side of the frame. The drive end of the control motor passes through the frame and is fixedly connected to a drive wheel. Belts are installed on the drive wheel and the driven wheel.

[0012] As a further preferred embodiment of the present invention, a discharge assembly for conveying substandard drug packaging boxes is provided below the frame.

[0013] In a further preferred embodiment of the present invention, the discharge assembly includes a carrier frame located below the machine frame. A conveyor belt is installed inside the carrier frame. A baffle is fixedly connected to one side of the carrier frame. Two sets of symmetrically arranged guide rods are slidably connected to the inner wall of the carrier frame. A buffer plate is fixedly connected to one end of the guide rod near the material conveying slide. Two sets of symmetrically arranged guide blocks are fixedly connected to one side of the carrier frame near the buffer plate. The guide blocks have a triangular cross-section and are used to guide the conveying of unqualified drug packaging boxes. A positioning block is fixedly connected to one end of the guide rod away from the buffer plate. A spring is fixedly connected to one side of the positioning block. The spring is sleeved on the guide rod, and one end of the spring is fixedly connected to the surface of the carrier frame.

[0014] Furthermore, the present invention also provides a control method for a pharmaceutical packaging box transfer system, comprising the following steps: S1. Start the conveyor component control motor, drive the driven wheel and belt to rotate synchronously, drive the roller inside the frame to rotate at a constant speed to form a conveying channel, place the medicine packaging box to be tested on the roller, and be driven by the roller to convey to the camera detection area. At the same time, start the servo motor in the push plate to drive the fan blade to rotate, and initially clean the empty medicine packaging box to the material conveying chute. S2. The camera below the positioning plate and protected by the cover plate captures real-time images of the appearance of the medicine packaging box, automatically identifies unqualified products that are not properly packaged or are not fully sealed, transmits the identification signal to the control module, and locks the position of the unqualified products and the conveying progress. S3. After receiving the identification signal, the control module starts the impurity removal component drive motor, which drives the swing arm to rotate. Through the swing arm guide hole and the slide block, the slide arm slides along the slide hole of the carrier plate, pushing the push plate to move towards the side of the defective product. S4. When the pusher moves, the servo motor drives the fan blades to rotate in the forward direction to generate directional airflow. Combined with the pushing force of the pusher, the defective products are guided to the corresponding side conveying slide. The magnet of the limit block on this side is magnetically attracted to the magnetic plate of the slide to achieve the positioning of the pusher. S5. When a defective product appears on the other side, the drive motor drives the swing arm to rotate in the opposite direction, the push plate moves to the other side, the servo motor drives the fan blades to reverse and generate reverse airflow, which, together with the pushing force, pushes the defective product into the material conveying slide on the other side. The magnet on the other side attracts the magnetic plate to complete the positioning, and the cycle realizes bidirectional screening. S6. Defective products fall into the discharge assembly via the conveyor chute. After being buffered by the guide rod and spring, they fall onto the conveyor belt and are then transferred to the subsequent processing production line by the conveyor belt.

[0015] In summary, the technical effects and advantages of this invention are as follows: 1) This invention provides a pharmaceutical packaging box transfer system and its control method. Relying on real-time image recognition technology from a camera, it accurately captures unqualified products such as those that are not properly packaged or have incomplete sealing.

The frame 2 contains a conveying assembly 3 for transferring pharmaceutical packaging boxes. Above the frame 2 is a removal assembly 4 for screening defective pharmaceutical packaging boxes. The removal assembly 4 includes a support rod 41, which is fixedly connected to the upper surface of the frame 2. A carrier plate 42 is fixedly connected to the upper end of the support rod 41. Two symmetrically arranged sliding holes 411 are formed on the upper surface of the carrier plate 42. A slide rail 418 is slidably connected to the sliding holes 411. A push plate for removing defective pharmaceutical packaging boxes is fixedly connected to the lower end of the slide rail 418. 410, the movement trajectory of the push plate 410 is perpendicular to the movement trajectory of the conveying component 3. A positioning plate 45 is fixedly connected to one side of the carrier plate 42, and a camera 46 is fixedly connected to the lower surface of the positioning plate 45. Relying on the real-time image recognition technology of the camera 46, it accurately captures unqualified products such as those that are not properly packaged or are not fully sealed. Combined with the mechanical pushing of the push plate 410 and the airflow assistance of the fan blade 421, a dual force is formed to ensure that unqualified products quickly leave the main conveyor line. The bidirectional screening design can be adapted to the material conveying slides 424 on both sides, without the need for frequent equipment adjustments, effectively improving screening efficiency and reducing the risk of unqualified products flowing into subsequent stages.

[0025] The system integrates the transfer of pharmaceutical packaging boxes with the screening of defective products. No additional independent screening equipment is required. The roller conveyor 31 continuously transfers the product while simultaneously performing real-time detection and diversion, reducing production process connections and shortening the overall production cycle. Defective products fall directly into the discharge assembly 5 via the conveying chute 424, achieving centralized transfer, avoiding material accumulation, and optimizing production site management.

[0026] The upper surface of the slide 418 is fixedly connected to a positioning rod 49, and one end of the positioning rod 49 is fixedly connected to a magnetic plate 48. The upper surface of the carrier plate 42 is fixedly connected to two symmetrically arranged limiting blocks 47. A magnet 412 is installed on one side of the limiting block 47. The magnet 412 and the magnetic plate 48 are magnetically attracted to each other, which is used to limit the slide 418 at both ends of the sliding hole 411. The sliding cooperation between the slide 418 and the sliding hole 411 and the attraction and positioning between the magnet 412 and the magnetic plate 48 ensure that the push plate 410 moves accurately and stably, reducing mechanical wear. The forward and reverse design of the fan blade 421 can flexibly adapt to the screening needs on both sides. The roller 31 conveying assembly 3 supports the transfer of medicine packaging boxes of different sizes and specifications. The structure of the material conveying slide 424 and the discharge assembly 5 can be adjusted according to the layout of the production site, adapting to large-scale production lines and small processing scenarios, and has strong versatility.

[0027] Among them, two L-shaped top rods 43 are fixedly connected to the side of the carrier plate 42 near the positioning plate 45. The upper end of the top rod 43 is fixedly connected to the cover plate 44. The cover plate 44 above the camera 46 can effectively block external interference light, improve the clarity and accuracy of image recognition, and avoid misjudgment caused by changes in light. The linkage control of the drive motor 414 and the servo motor 420 is fast and can accurately lock the position of the defective product and complete the push. The screening accuracy is high, which further ensures the overall quality of the drug packaging.

[0028] The frame 2 is fixedly connected to two sides of a conveying slide 424. A baffle 425 is fixedly connected to the upper surface of the conveying slide 424 to guide the unqualified drug packaging boxes pushed by the pusher plate 410 into the conveying slide 424. From material transfer, image recognition, bidirectional pushing to centralized transfer of unqualified products, no manual intervention is required throughout the process. Only periodic checks on the equipment's operating status are needed. The detection accuracy of the camera 46 is not affected by human fatigue and has strong screening consistency. Compared with the traditional manual screening mode, it can greatly reduce manpower input and reduce the quality risks and management costs caused by human error.

[0029] The inner wall of the push plate 410 is fixedly connected to a bracket 419, and a servo motor 420 is installed inside the bracket 419. The output end of the servo motor 420 is fixedly connected to a fan blade 421. Both sides of the push plate 410 are provided with mounting grooves 422, and a protective net 423 is installed in the mounting grooves 422. During the pushing process of the push plate 410, the airflow generated by the fan blade 421 can buffer the impact force of mechanical pushing and prevent defective products from being deformed due to collision. The buffer plate 54 of the discharge component 5 cooperates with the spring 58 to effectively absorb the impact force when defective products fall and prevent the packaging box from being damaged. It is especially suitable for pharmaceutical packaging boxes with brittle materials or fragile packaging, ensuring the feasibility of subsequent material processing.

[0030] The conveying assembly 3 includes rollers 31, which are rotatably connected to the inner wall of the frame 2. There are multiple rollers 31, which are arranged at equal intervals. A shaft on one side of the roller 31 passes through the frame 2 and is fixedly connected to a driven wheel 32. A control motor 35 is fixedly connected to one side of the frame 2. The drive end of the control motor 35 passes through the frame 2 and is fixedly connected to a drive wheel 34. A belt 33 is installed on the drive wheel 34 and the driven wheel 32.

[0031] The lower part of the frame 2 is equipped with a discharge assembly 5 for conveying substandard drug packaging boxes.

[0032] The discharge assembly 5 includes a carrier frame 51 located below the frame 2. A conveyor belt 52 is installed inside the carrier frame 51. A baffle 53 is fixedly connected to one side of the carrier frame 51. Two sets of symmetrically arranged guide rods 56 are slidably connected to the inner wall of the carrier frame 51. A buffer plate 54 is fixedly connected to one end of the guide rod 56 near the material conveying slide 424. Two sets of symmetrically arranged guide blocks 55 are fixedly connected to one side of the carrier frame 51 near the buffer plate 54. The cross-section of the guide block 55 is triangular and is used to guide the conveying of unqualified drug packaging boxes. A positioning block 57 is fixedly connected to one end of the guide rod 56 away from the buffer plate 54. A spring 58 is fixedly connected to one side of the positioning block 57. The spring 58 is sleeved on the guide rod 56, and one end of the spring 58 is fixedly connected to the surface of the carrier frame 51.

[0033] One method for controlling a pharmaceutical packaging box transfer system includes the following steps: S1. Start the conveyor assembly 3 and control the motor 35. Drive the driven wheel 32 to rotate synchronously through the drive wheel 34 and belt 33. Drive the roller 31 in the frame 2 to rotate at a constant speed to form a conveying channel. Place the medicine packaging box to be tested on the roller 31. Driven by the roller 31, it is conveyed to the detection area of ​​the camera 46. At the same time, start the servo motor 420 in the push plate 410 to drive the fan blade 421 to rotate, and initially clean the empty medicine packaging box to the conveying slide 424. S2. The camera 46, located below the positioning plate 45 and protected by the cover plate 44, captures real-time images of the appearance of the medicine packaging box, automatically identifies unqualified products that are not properly packaged or are not fully sealed, transmits the identification signal to the control module, and locks the position of the unqualified products and the conveying progress. S3. After receiving the identification signal, the control module starts the impurity removal component 4 drive motor 414, which drives the swing arm 415 to rotate. The swing arm 415 guide hole 416 cooperates with the slide 418 protrusion 417, which drives the slide 418 to slide along the slide hole 411 of the carrier plate 42, pushing the push plate 410 to move towards the non-conforming product side. S4. When the push plate 410 moves, the servo motor 420 drives the fan blade 421 to rotate in the forward direction to generate directional airflow. Combined with the pushing force of the push plate 410, the defective products are guided to the corresponding side conveying slide 424. The magnet 412 of the side limiting block 47 and the magnetic plate 48 of the slide 418 are magnetically attracted to achieve the positioning of the push plate 410. S5. When a defective product appears on the other side, the drive motor 414 drives the swing arm 415 to rotate in the opposite direction, the push plate 410 moves to the other side, the servo motor 420 drives the fan blade 421 to reverse and generate reverse airflow, which, together with the pushing force, pushes the defective product into the material conveying slide 424 on the other side, and the magnet 412 on the other side attracts the magnetic plate 48 to complete the positioning, and the cycle realizes bidirectional screening. S6. Defective products fall into the discharge assembly 5 through the conveyor chute 424. After being buffered by the guide rod 56 and the spring 58, they fall onto the conveyor belt 52 and are then transferred to the subsequent processing production line by the conveyor belt 52.

[0034] The working principle of this invention is as follows: The control motor 35 of the conveying component 3 is started. The control motor 35 drives all driven wheels 32 to rotate synchronously through the drive wheel 34 and belt 33, thereby driving multiple rollers 31 in the frame 2 to rotate at a constant speed, forming a continuous conveying channel. The medicine packaging boxes to be tested are neatly placed on the rollers 31. The rollers 31 drive the packaging boxes to be smoothly conveyed to the detection area of ​​the camera 46, preparing for subsequent screening. The servo motor 420 is started to drive the fan blades 421 to rotate, thereby blowing the empty medicine packaging boxes into the conveying chute 424. The camera 46 is fixed below the positioning plate 45 and protected by the cover plate 44 above it to prevent external light from interfering with the detection accuracy. When the medicine packaging box passes directly below the camera 46, the camera 46 captures the appearance image of the packaging box in real time, automatically identifies unqualified products such as those that are not properly packaged or are not fully sealed, and transmits the identification signal to the control module in a synchronous manner to lock the position and conveying progress of the unqualified products. When identifying defective products, the drive motor 414 starts and drives the swing arm 415 to rotate. The swing arm 415, through the cooperation of the guide hole 416 and the protrusion 417, drives the slide 418 to slide laterally along the slide hole 411 of the carrier plate 42, thereby pushing the push plate 410 to move towards the defective product side. At the same time, the servo motor 420 inside the push plate 410 starts, driving the fan blade 421 to rotate in the forward direction, generating directional airflow. Combined with the mechanical pushing force of the push plate 410, the defective products are smoothly guided to the conveying slide 424 on one side. Then, the servo motor 420 is controlled to drive the fan blade 421 to rotate in the reverse direction, thereby continuously cleaning the empty medicine packaging boxes on the production line. At this time, the magnet 412 on the side limiting block 47 is magnetically attracted to the magnetic plate 48 of the slide 418, thereby positioning the push plate 410. When a defective product appears on the other side, the drive motor 414 drives the swing arm 415 to rotate in the opposite direction, and the push plate 410 moves to the other side. Combined with the airflow generated by the fan blade 421, the defective product is pushed into the material conveying chute 424 on the other side. The magnet 412 on the other side attracts the magnetic plate 48 to complete the positioning, and the two-way screening is realized in a cycle. Defective products fall from the conveyor chute 424 into the discharge assembly 5 below. When they come into contact with the buffer plate 54, the guide rod 56 slides along the carrier 51, and the spring 58 is compressed to generate a buffering force, preventing the packaging box from being damaged by the impact of falling. The buffered defective products fall onto the conveyor belt 52 of the carrier 51, and the conveyor belt 52 smoothly transports them to the subsequent processing production line, realizing the centralized transfer of defective products.

10. A control method for a pharmaceutical packaging box transfer system, characterized in that, Includes the following steps: S1. Start the conveying assembly (3) and control the motor (35). Drive the driven wheel (32) to rotate synchronously through the drive wheel (34) and belt (33), which drives the roller (31) inside the frame (2) to rotate at a constant speed to form a conveying channel. Place the medicine packaging box to be tested on the roller (31) and drive it to be conveyed to the detection area of ​​the camera (46) by the roller (31). At the same time, start the servo motor (420) inside the push plate (410) to drive the fan blade (421) to rotate, and initially clean the empty medicine packaging box to the conveying slide (424). S2. The camera (46) located below the positioning plate (45) and protected by the cover plate (44) captures images of the appearance of the medicine packaging box in real time, automatically identifies unqualified products that are not properly packaged or not fully sealed, transmits the identification signal to the control module, and locks the position of the unqualified products and the conveying progress. S3. After receiving the identification signal, the control module starts the impurity removal component (4) drive motor (414), which drives the swing arm (415) to rotate. Through the guide hole (416) of the swing arm (415) and the protrusion (417) of the slide (418), the slide (418) is driven to slide along the sliding hole (411) of the carrier plate (42), pushing the push plate (410) to move towards the side of the defective product. S4. When the push plate (410) moves, the servo motor (420) drives the fan blade (421) to rotate in the forward direction to generate directional airflow.
