Description

Technical Field

[0001] This application belongs to the field of infusion bag packaging, and specifically relates to an infusion bag tray arrangement device. Background Technology

[0002] In the medical and pharmaceutical industry, the production of infusion bags is a crucial step. The efficiency and reliability of its filling, transfer, tray placement, and sterilization processes directly impact product quality and production efficiency. Currently, after being filled with medication, infusion bags are typically transported to the tray placement station via a conveyor line. Operators manually remove the bags from the conveyor line and neatly place them into trays, which are then transported to the sterilization process for disinfection. However, this traditional manual operation mode has many problems, severely restricting further improvements in production efficiency and product quality.

[0003] First, due to the fast operating cycle of the conveyor line, four operators are typically required to work together simultaneously to ensure that infusion bags are placed in the trays promptly without any omissions. This not only increases labor costs but also demands a high degree of coordination from the operators. If any operator is even slightly slow or makes a mistake, it can lead to an accumulation of infusion bags or empty trays, affecting subsequent sterilization processes and potentially causing production interruptions or material waste. Furthermore, prolonged high-intensity work can lead to operator fatigue, a gradual decline in efficiency, and an increase in error rates, further exacerbating production instability.

[0004] Secondly, the physical characteristics of infusion bags also pose significant challenges to manual operation. Different sizes of infusion bags have varying liquid levels, and their surfaces may wrinkle due to compression during filling or transport. These factors make it difficult for operators to precisely control the handling and placement. Especially when the material positioning accuracy of the conveyor line is low, the infusion bags may shift, further increasing the risk of handling failure. These problems not only reduce production efficiency but may also lead to damage or contamination of the infusion bags due to improper handling, affecting product quality and safety.

[0005] Furthermore, with the increasing demand for infusion bags, manufacturers need to achieve large-scale, continuous production, a requirement that traditional manual tray placement cannot meet. On the one hand, labor costs remain high, especially when multiple people are needed for collaborative work, putting immense pressure on companies to manage their workforce. On the other hand, manual operation has inherent efficiency limitations, making it difficult to increase overall production capacity simply by speeding up the process. Therefore, automating the infusion bag tray placement process, reducing reliance on manual labor, and simultaneously improving the accuracy and reliability of grasping and placing have become pressing technical challenges for the industry.

[0006] While existing automation solutions utilize robotic arms or gripper technologies to some extent, they still have many shortcomings in grasping flexible and deformable objects like infusion bags. For example, traditional robotic arms struggle to adapt to infusion bags of different sizes and surface conditions, resulting in low success rates. Furthermore, the accuracy and speed of vision positioning systems often fail to meet the demands of high-speed conveyor lines, hindering the practical implementation of automation solutions in actual production. Therefore, there is a need for an automated tray-loading system that can adapt to the characteristics of infusion bags, accurately grasp them, and provide high efficiency and stability. This is crucial for improving pharmaceutical production efficiency, reducing costs, and ensuring product quality.

[0007] Currently, the tray placement process in the production of infusion bags still relies heavily on manual labor, resulting in low efficiency, high cost, and poor stability. There is an urgent need for a tray placement device that can overcome the difficulties in gripping and placing infusion bags, achieving efficient, precise, and reliable automated operation to meet the demands of the medical and pharmaceutical industry for large-scale continuous production. Utility Model Content

[0008] This application provides an infusion bag tray device that solves at least one of the above-mentioned technical problems.

[0009] The technical solution adopted in this application is as follows:

[0010] An infusion bag tray placement device includes a frame with a working area for a conveyor belt to pass through. The working area has a material tray. The infusion bag tray placement device also includes a robot component that moves along the top of the frame and a suction cup gripper component connected to the robot component. The robot component is fixed to the top of the frame, and at least two sets of the robot components are offset relative to the axial direction of the conveyor belt. Each set of the robot components drives the corresponding suction cup gripper component to pick up the material from the conveyor belt and place it on the material tray.

[0011] Preferably, the suction cup gripper assembly includes a connecting plate, the top of the connecting plate is provided with a gripper flange for connection to the robot assembly, the bottom of the connecting plate is provided with a vacuum chamber, the vacuum chamber is provided with a vacuum suction cup assembly, and the vacuum suction cup assembly includes multiple vacuum suction cups.

[0012] Preferably, the top of the connecting plate is provided with a vent that communicates with the inner cavity of the vacuum chamber, and the vent is provided with an air pipe for introducing negative pressure air.

[0013] Preferably, the gripper flange is located at the center of the connecting plate, the air pipes are located on both sides of the gripper flange, and each air pipe is connected to a different vacuum chamber.

[0014] Preferably, the infusion bag tray device further includes a negative pressure tank assembly connected to the robot assembly. The negative pressure tank assembly is located at the top of the frame, and the negative pressure tank assembly includes a negative pressure tank and a connector. The connector is connected to the air tube to provide negative pressure to the suction cup assembly.

[0015] Preferably, at least two vacuum chambers are arranged along the axial direction of the connecting plate, and each vacuum chamber is provided with multiple vacuum suction cup groups.

[0016] Preferably, the vacuum suction cups of each vacuum suction cup group are evenly distributed circumferentially.

[0017] Preferably, the infusion bag tray device includes a side plate fixedly connected to the connecting plate and a bottom plate connected to the side plate. The bottom plate is arranged opposite to the connecting plate so that the connecting plate, the side plate and the bottom plate enclose the vacuum chamber.

[0018] Preferably, the robot assembly includes a first working direction for moving toward the conveyor belt and a second working direction for moving toward the tray, with at least two sets of robot assemblies having their first working directions opposite each other and their second working directions opposite each other.

[0019] Preferably, the infusion bag tray device further includes a vision light box disposed on the conveyor belt, the vision light box being equipped with a camera, the shooting area of ​​the camera covering the radial width of the conveyor belt.

[0020] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0021] This solution employs multiple sets of robotic components working collaboratively, adapting to the pace of high-speed conveyor lines, improving work efficiency, achieving continuous production, significantly reducing labor costs, and avoiding efficiency decline and increased error rates caused by human fatigue. In this solution, the robotic components move along the top of the frame and are offset relative to the conveyor belt axis, allowing the working areas of different robots to partially overlap but without interference. This ensures that the gripping range covers the entire width of the conveyor belt while avoiding the risk of collisions between robotic arms, improving system stability and reliability. Furthermore, because infusion bags may have differences in liquid level or surface wrinkles, traditional mechanical grippers struggle to grip them stably. This solution uses suction cup gripper components, utilizing negative pressure adsorption to pick up infusion bags, adapting to infusion bags of different shapes and materials, improving the success rate of gripping, avoiding downtime or material waste due to gripping failures, and enhancing gripping accuracy.

[0022] Furthermore, in this solution, each group of robot components can be controlled independently. If one group malfunctions, the other robot components can continue to operate, reducing the risk of system downtime. The staggered arrangement allows for greater flexibility in increasing or decreasing the number of robot components, adapting to different production capacity requirements.

[0038] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0040] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0043] This application provides an infusion bag tray arrangement device, such as... Figures 1 to 5As shown, the device includes a frame 1, which has a working area 11 through which the conveyor belt 7 passes. The working area 11 has a material tray 3. The infusion bag 8 tray device also includes a robot component 2 that moves along the top of the frame 1 and a suction cup gripper component 4 connected to the robot component 2. The robot component 2 is fixed to the top of the frame 1, and at least two sets of robot components 2 are offset relative to the axial direction of the conveyor belt 7. Each set of robot components 2 drives the suction cup gripper component 4 connected to it to pick up the material from the conveyor belt 7 and place it on the material tray 3.

[0044] This solution employs multiple robot components 2 working collaboratively, adapting to the pace of high-speed conveyor lines, improving work efficiency, achieving continuous production, significantly reducing labor costs, and avoiding efficiency decline and error rate increases caused by human fatigue. In this solution, robot components 2 move along the top of the frame 1 and are axially offset relative to the conveyor belt 7, allowing the working areas of different robots to partially overlap but without interference. This prevents the infusion bags 8 from shifting during transport and becoming ungraspable. This solution ensures the gripping range covers the entire width of the conveyor belt while avoiding the risk of collisions between robotic arms, improving system stability and reliability. Furthermore, traditional mechanical grippers struggle to stably grip infusion bags 8 due to potential liquid level differences or surface wrinkles. This solution uses a suction cup gripper component 4, employing negative pressure adsorption to pick up the infusion bags 8. This adaptable to infusion bags 8 of different shapes and materials improves the gripping success rate, avoids downtime or material waste due to gripping failures, and enhances gripping accuracy.

[0045] Furthermore, in this solution, each group of robot components 2 can be independently controlled. If one group malfunctions, the other robot components 2 can still continue to operate, reducing the risk of system downtime. The staggered arrangement allows for greater flexibility in increasing or decreasing the number of robot components 2, adapting to different production capacity requirements.

[0046] In one embodiment, such as Figure 4 As shown, the suction cup gripper assembly 4 includes a connecting plate 41. The top of the connecting plate 41 is provided with a gripper flange 44 that is connected to the robot assembly 2. The bottom of the connecting plate 41 is provided with a vacuum chamber 42. The vacuum chamber 42 is provided with a vacuum suction cup assembly 43, which includes multiple vacuum suction cups 431.

[0047] In this design, the vacuum chamber 42 ensures uniform negative pressure distribution, preventing insufficient suction force from a single suction cup on the infusion bag 8 due to uneven surfaces (such as wrinkles). Multiple vacuum suction cups 431 work together, maintaining stable grip even if some suction cups do not fully adhere, making it particularly suitable for flexible and easily deformable infusion bags 8, thus improving gripping accuracy and stability. In this design, the gripper flange 44 is fixed to the connecting plate 41 with screws 47. The other end of the gripper flange 44 is installed at the end of the robot assembly 2. The rigid connection between the connecting plate 41 and the gripper flange 44 ensures that the suction cup gripper assembly 4 will not shake or shift during rapid movement of the robot assembly 2, guaranteeing placement accuracy. Simultaneously, the vacuum chamber 42 is integrated into the bottom of the connecting plate 41, resulting in a lightweight overall structure that reduces robot load and improves movement speed and responsiveness. Furthermore, the vacuum chamber 42 and the suction cup assembly adopt a modular design, allowing individual replacement of damaged suction cups without affecting overall functionality. In addition, vacuum adsorption results in less wear compared to mechanical grippers, and has higher long-term stability, which helps reduce equipment maintenance frequency and costs.

[0048] Furthermore, the vacuum suction cup assembly 43 in this design employs a multi-suction cup layout. In actual production, the suction points can be adjusted according to the size of the infusion bag 8. For example, for larger infusion bags 8, more suction cups can be used to enhance suction force; for smaller infusion bags 8, some suction cups can be used selectively to avoid over-adsorption and deformation. This flexibility allows the device to adapt to various product specifications without frequent clamp changes.

[0049] The top of the connecting plate 41 is provided with a vent 411 that communicates with the inner cavity of the vacuum chamber 42, and a vent pipe 412 for introducing negative pressure is provided at the vent 411.

[0050] The vent 411 is directly connected to the inner cavity of the vacuum chamber 42, and negative pressure is quickly introduced through the air pipe 412, enabling the suction cup to form suction force in a very short time, adapting to the cycle requirements of high-speed production lines. Compared with traditional single-point negative pressure systems, this facilitates faster gripping and releasing actions, reducing waiting time.

[0051] In this design, air pipes 412 are located on both sides of the gripper flange 44 and connected to different vacuum chambers 42, so that the negative pressure is evenly distributed to each suction cup assembly. Even if one air pipe 412 is temporarily blocked or the pressure fluctuates, the other side can still maintain part of the adsorption function, reducing the risk of gripping failure due to unstable air pressure.

[0052] The external design of the air tube 412 facilitates quick connection to an external negative pressure source (such as a negative pressure tank) and allows for easy inspection of the airway for blockages. If a section of the air tube 412 is damaged, it can be replaced individually without disassembling the entire gripper assembly, reducing maintenance difficulty and downtime. Furthermore, the suction force can be flexibly controlled by adjusting the negative pressure intensity of the air tube 412. For example, for heavier infusion bags 8, the negative pressure can be increased to ensure a stable grip; for thin or easily deformable infusion bags 8, the negative pressure can be decreased to prevent deformation during suction, thereby improving adaptability and product protection.

[0053] Furthermore, each air pipe 412 can be configured to correspond to a vacuum chamber 42, or multiple air pipes 412 can be configured to correspond to a vacuum chamber 42, or one air pipe 412 can correspond to a set of vacuum suction cups 43. The number of air pipes 412 can be determined according to actual production needs.

[0054] In one embodiment, such as Figure 4 As shown, the gripper flange 44 is located at the center of the connecting plate 41, and the air pipes 412 are located on both sides of the gripper flange 44, with each air pipe 412 connected to a different vacuum chamber 42.

[0055] In this design, the gripper flange 44 is positioned at the center of the connecting plate 41, ensuring even force distribution on the robot during high-speed movement and preventing swaying or shaking caused by a shift in the center of gravity, thus improving placement accuracy. Simultaneously, air pipes 412 are symmetrically distributed on both sides of the gripper flange 44, ensuring a balanced supply of negative pressure airflow and preventing unstable adsorption due to insufficient air pressure on one side. The symmetrical distribution of the air pipes 412 results in a clear air path structure, facilitating quick location and replacement of faulty components, reducing downtime, and improving production efficiency.

[0056] Preferably, each air tube 412 is connected to a different vacuum chamber 42, forming an independent negative pressure circuit. Even if one air tube 412 or vacuum chamber 42 fails, the other side can still maintain the adsorption function, reducing the risk of overall grasping failure due to local failure and improving the fault tolerance of the system.

[0057] Furthermore, in this design, the distribution of adsorption force can be flexibly adjusted by independently controlling the negative pressure intensity of the two air chambers 412. For example, for a wider infusion bag 8, both vacuum chambers 42 can be activated simultaneously to enhance adsorption force; for a narrower infusion bag 8, single-sided adsorption can be selected to reduce energy consumption and improve adaptability.

[0058] In one embodiment, such as Figures 1 to 3 As shown, the infusion bag 8 tray device also includes a negative pressure tank assembly 5 connected to the robot assembly 2. The negative pressure tank assembly 5 is located on the top of the frame 1 and includes a negative pressure tank and a connector. The connector is connected to the air pipe 412 to provide negative pressure to the suction cup assembly.

[0059] In this solution, the negative pressure tank assembly 5 is integrated into the top of the frame 1 and directly connected to the air pipe 412 via a connector. This allows for rapid response to the negative pressure requirements of the suction cup gripper, avoiding air pressure loss or delay caused by long-distance air transport and improving adsorption efficiency and stability. Furthermore, integrating the negative pressure tank assembly 5 into the frame 1 eliminates the need for additional floor space or external air source equipment, resulting in a more compact overall structure suitable for space-constrained production environments. The negative pressure tank in the assembly 5 can store a certain amount of negative pressure, maintaining adsorption function for a short period even during brief power outages or air source fluctuations, preventing material spillage or production interruptions due to sudden malfunctions.

[0060] Furthermore, the connectors in the negative pressure tank assembly 5 adopt a standardized design, which facilitates quick disassembly and replacement.

[0061] It is understandable that the negative pressure tank and connector in the negative pressure tank assembly 5 can be set up with the help of existing technology. There are no technical barriers to their use in this solution. Therefore, the structure of the negative pressure tank and connector will not be disassembled and described separately here.

[0062] In one embodiment, at least two vacuum chambers 42 are arranged axially along the connecting plate 41, and each vacuum chamber 42 is provided with multiple vacuum suction cup groups 43.

[0063] In a preferred embodiment, two vacuum chambers 42 are arranged axially along the connecting plate 41. Each chamber is equipped with an independent vacuum suction cup assembly 43, which can cover a larger area of ​​the infusion bag 8 surface. Even if the infusion bag 8 has wrinkles or uneven liquid levels, stable adsorption can still be ensured, reducing the failure rate of gripping. This is beneficial for improving the adsorption coverage area and enhancing gripping stability. If one vacuum chamber 42 or suction cup assembly fails, the other chambers can still maintain the adsorption function, reducing the frequency of downtime maintenance and ensuring continuous production.

[0064] Multiple vacuum chambers 42 can be controlled independently. Depending on the size and shape of the infusion bag 8, some chambers can be selectively activated to avoid deformation or energy waste caused by excessive adsorption, thereby improving adaptability and economy and flexibly grasping infusion bags 8 of different sizes.

[0065] Meanwhile, setting up multiple vacuum chambers 42 can achieve zoned negative pressure control, providing negative pressure only in the areas that need adsorption, avoiding energy waste caused by global high negative pressure, reducing operating costs, optimizing airflow distribution, and reducing energy consumption.

[0066] Preferably, the vacuum suction cups 431 of each vacuum suction cup group 43 are evenly distributed circumferentially.

[0067] This design sets the vacuum suction cups 431 to be evenly distributed around the circumference, ensuring that the suction force is applied evenly to the surface of the infusion bag 8, and avoiding deformation or damage caused by excessive local force.

[0068] The evenly distributed suction cups can better conform to the wrinkles or uneven surfaces of the infusion bag 8, ensuring reliable gripping even if the infusion bag 8 shifts or deforms during transport, thus reducing the miss rate. It also enhances adaptability to irregular shapes.

[0069] The standardized distribution of the vacuum chuck 431 facilitates quick detection and replacement of damaged units, reducing maintenance time and improving equipment availability.

[0070] In one embodiment, such as Figure 4 , Figure 5 As shown, the infusion bag 8 tray device includes a side plate 45 fixedly connected to the connecting plate 41 and a bottom plate 46 connected to the side plate 45. The bottom plate 46 is arranged opposite to the connecting plate 41 so that the connecting plate 41, the side plate 45 and the bottom plate 46 enclose a vacuum chamber 42.

[0071] In this design, a connecting plate 41, side plate 45, and bottom plate 46 enclose a sealed vacuum chamber 42, ensuring that negative pressure is concentrated on the suction cup area, reducing air pressure leakage, and improving adsorption efficiency and stability. It is understood that a sealing ring is added when the side plate 45 and connecting plate 41 are enclosed to enhance the sealing effect of the vacuum chamber 42. The reinforced design of the side plate 45 and bottom plate 46 makes the vacuum chamber 42 less prone to deformation during high-speed movement, maintaining high precision over long-term use and extending the equipment's service life. This modular structure of the vacuum chamber 42 facilitates manufacturing and assembly, while supporting rapid disassembly and maintenance, reducing production costs and downtime. It is understood that since the vacuum chamber 42 is a cavity, the vacuum suction cup 431 can simply be placed on the bottom plate 46.

[0072] Meanwhile, the vacuum chamber 42 can be adjusted in size or have additional partitions added as needed to accommodate larger or smaller infusion bags 8, thus improving the versatility of the device.

[0073] In one embodiment, the robot component 2 includes a first working direction for moving toward the conveyor belt 7 and a second working direction for moving toward the tray 3. At least two sets of robot components 2 are arranged with their first working directions opposite each other and their second working directions opposite each other.

[0074] The robot components 2 are positioned opposite each other in their first working direction (moving towards the conveyor belt 7) and in their second working directions (moving towards the material tray 3). This arrangement ensures that the movement paths of multiple robot components 2 do not interfere with each other, maximizing the use of limited space, optimizing workspace utilization, and improving collaborative efficiency. The opposite orientation prevents collisions or path conflicts between robots in the material tray 3 area, allowing each robot component 2 to operate in parallel, shortening the single tray loading cycle, reducing waiting time, increasing cycle speed, and adapting to the needs of high-speed production lines.

[0075] Meanwhile, the regularized setting of the working direction of robot component 2 makes the robot's motion trajectory easier to plan and optimize, reducing debugging time and improving system stability. Furthermore, this layout allows for the addition of more robot components 2 without altering the existing structure to meet higher production capacity demands.

[0076] It is understandable that robot component 2 in this solution can be composed of Bat1300-A6 parallel robot, trachea 412 clamp, etc., which can be achieved with the help of existing technology, and will not be elaborated here.

[0077] In one embodiment, such as Figure 3 As shown, the infusion bag 8 tray placement device also includes a vision light box 6 installed on the conveyor belt 7. The vision light box 6 is equipped with a camera, and the camera's shooting area covers the radial width of the conveyor belt 7. With the camera covering the radial width of the conveyor belt 7, the position and orientation of the infusion bags 8 can be detected in real time. Even if there is material offset or stacking, the robot component 2 can still accurately adjust the suction point, improving positioning accuracy and reducing the grasping failure rate. The vision light box 6 provides uniform illumination, reducing glare or shadow interference, ensuring that the camera clearly captures the outline and surface features (such as wrinkles and liquid levels) of the infusion bags 8, enhancing the ability to recognize complex surfaces.

[0078] The vision lightbox 6 can be configured to consist of a lightbox body, a camera mounting plate, a camera mounting block, a standard light source mounting plate, a camera, a lens, a controller, and a light source (using existing technology). Since the infusion bags 8 may shift during transportation, resulting in inconsistent material spacing, the vision lightbox 6 adds visual image recognition, feeding back to the PLC for identification, enabling the robot to accurately grasp them. Furthermore, the recorded production data can be used to analyze key indicators such as grasping success rate and cycle time, facilitating data traceability and process optimization, and providing a valid basis for subsequent process improvements. Any aspects not mentioned in this application can be implemented using or referencing existing technologies.

[0079] Furthermore, it should be noted that the visual light box 6 is placed on the material tray 3, and a clearance space is provided between the visual light box 6 and the material tray 3 to allow the conveyor belt 7 to pass through, so that the conveyor belt 7 passes through the bottom of the visual light box 6. The conveyor belt 7 moves along the conveyor line. Multiple placement points can be set on the overall conveyor line, thereby setting multiple sets of tray-slab devices. Each set of tray-slab devices can be independently controlled, and the number of tray-slab devices to be activated can be set according to production needs.
