Description

Technical Field

[0001] This utility model relates to the field of biopharmaceutical technology, and in particular to a mobile weighing device for biopharmaceutical production. Background Technology

[0002] Currently, in the field of biopharmaceutical manufacturing, the weighing process of mobile tanks is crucial for precise control of the production process. With the continuous development of biopharmaceutical manufacturing technologies, higher requirements are being placed on the accuracy, efficiency, and environmental adaptability of mobile tank weighing.

[0003] Currently, mobile container weighing faces numerous challenges, and its practical application still exhibits the following shortcomings: First, traditional manual handling and weighing methods require significant manpower. Furthermore, the weight of a mobile container, including the container itself, can reach approximately 200 kilograms. In cleanrooms with limited operating space, manual lifting is not only arduous but also highly prone to causing personal injury accidents, seriously threatening the safety of operators. Second, while using fixed gantry cranes or overhead cranes for lifting and weighing can alleviate some of the manpower issues, these devices are bulky and difficult to adapt to the confined space of cleanrooms. Moreover, their materials are prone to oxidation, making it difficult to meet the stringent cleanliness standards required by cleanrooms.

[0004] Meanwhile, in existing wire drawing machine weighing technology, the wire frames are typically transported to a weighbridge using a forklift. This method not only requires two transfers, which is time-consuming, labor-intensive, and inefficient, but also has limited accuracy, is difficult to calibrate, and is prone to counting errors. Similarly, in biopharmaceutical production, using a similar weighing method would also fail to meet the demand for precise weight control of materials during the production process.

[0005] In summary, existing weighing technologies have many shortcomings in the field of biopharmaceutical production, and cannot meet the requirements of high efficiency, accuracy, safety, and clean environment adaptability for weighing mobile tanks during the production process. There is an urgent need for an innovative weighing technology to solve these problems. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing mobile tank weighing technology, such as low efficiency, poor accuracy, and difficulty in meeting safety and clean environment requirements, and to provide a mobile weighing device for bioproduct production.

[0007] This utility model is achieved through the following technical solution: a mobile weighing device for biological product production, including a frame, a motor with a rack at the top of the frame, the rack being able to move up and down with the rotation of the motor; a weighing module suspended below the rack, a hook below the weighing module, and a mobile tank connected to the weighing module through the hook; and wheels at the bottom of the frame, which drive the frame to move freely.

[0008] This invention features a rack-and-pinion motor mounted on top of a frame, a weighing module suspended below, and hooks connecting to the mobile tank. The frame is also equipped with wheels, allowing the weighing device to move freely over the mobile tank for weighing. This solves the problems of the cumbersome and dangerous nature of traditional manual weighing and the inflexibility of fixed weighing equipment. It can adapt to the weighing needs of mobile tanks in different locations within a bioproduct production workshop, improving the convenience and flexibility of weighing and effectively reducing labor costs and safety risks.

[0009] A further improvement of this utility model is that the motor is a servo motor, which is connected to a controller. The controller is fixed on the frame and can control the rotation speed of the servo motor and the rotation angle of the motor shaft, thereby enabling precise control of the lifting height of the rack.

[0010] This invention employs a servo motor connected to a controller, which precisely controls the rotation speed and angle of the servo motor to accurately control the lifting height of the rack. This makes the weighing device more precise when lifting and lowering the mobile tank, avoiding damage to the mobile tank due to improper lifting height control. At the same time, it can more accurately lift the mobile tank to the appropriate weighing height, ensuring the stability and accuracy of the weighing process, and further improving the accuracy and safety of weighing.

[0011] A further improvement of this utility model is that a pressure sensor is installed inside the weighing module, and the pressure sensor is connected to a display screen, which is installed on the controller to display the weight data of the moving tank in real time.

[0012] The internal pressure sensor of the weighing module is connected to the display screen installed on the controller, which displays the weight data of the moving tank in real time. This allows operators to intuitively obtain weighing information while controlling the equipment, eliminating the need for additional data reading. This improves weighing efficiency, reduces operating steps, and avoids errors that may occur due to manual secondary data reading, making the weighing process more convenient, efficient, and accurate.

[0013] A further improvement of this utility model is that the frame is made of stainless steel, and the surface of the stainless steel is passivated to improve its corrosion resistance and meet the cleanliness requirements of the bioproduct production workshop.

[0014] The frame is made of passivated stainless steel, which meets the cleanliness requirements of bioproduct production workshops, avoids the problem of easy oxidation of traditional materials, reduces the risk of contamination of bioproducts by impurities caused by material corrosion, ensures the cleanliness of the production environment, is conducive to the safe production of bioproducts, extends the service life of the weighing device, and reduces equipment maintenance costs.

[0015] A further improvement of this utility model is that the wheels are omnidirectional wheels equipped with a braking device, which can fix the position of the frame during weighing to prevent the frame from moving.

[0016] The wheels are omnidirectional wheels equipped with brakes. During weighing, the position of the frame can be fixed by the brakes to prevent the frame from moving and interfering with the weighing results. This ensures the accuracy and reliability of the weighing data, improves the stability of the weighing device, avoids shaking of the moving tank due to frame movement, and ensures the safety of the weighing operation.

[0017] A further improvement of this utility model is that a protective railing is provided around the frame to prevent the tank from colliding with surrounding objects when it shakes during the weighing process.

[0018] The installation of protective railings around the frame effectively prevents the moving tank from shaking and colliding with surrounding objects during the weighing process, protecting other equipment and items in the workshop, avoiding equipment damage or items falling due to collisions, reducing the probability of production accidents, ensuring the safety and stability of the production environment, and ensuring that the weighing operation is carried out in a safe environment.

[0019] A further improvement of this utility model is that the hook is an adjustable hook with an adjustment knob. The opening size of the hook can be adjusted by the adjustment knob to accommodate mobile tanks of different sizes.

[0020] The hook is adjustable and equipped with an adjustment knob, which can adjust the opening size to accommodate mobile tanks of different specifications. This increases the versatility of the weighing device, eliminating the need to equip different weighing devices for mobile tanks of different specifications, improving the efficiency of the equipment, reducing production costs, and meeting the weighing needs of mobile tanks of various specifications in the production of biological products.

[0021] A further improvement of this utility model is that the weighing module and the rack are connected by a shock-absorbing device, which can reduce the impact of vibrations generated during the lifting and lowering of the moving tank on the weighing results.

[0022] The weighing module is connected to the rack and pinion with a shock-absorbing device, which can reduce the impact of vibration generated during the lifting and lowering of the mobile tank on the weighing results, further improving the accuracy and stability of the weighing, avoiding fluctuations in the weighing data due to vibration, ensuring the reliability of the weighing results, and making the weighing data more accurately reflect the weight of the mobile tank, providing a reliable basis for the precise allocation of materials in the production of bioproducts.

[0023] A further improvement of this utility model is that an alarm is installed on the frame, and the alarm is connected to the weighing module. When the weight measured by the weighing module exceeds the preset safe weight range, the alarm will sound.

[0024] An alarm connected to the weighing module is installed on the frame. When the weight measured by the weighing module exceeds the preset safety range, an alarm is issued, which can promptly remind the operator to avoid equipment damage or safety accidents caused by overload. This ensures the safety of equipment and personnel, enhances the safety and reliability of the weighing device, and ensures the safe operation of the weighing process in the production of biological products.

[0025] A further improvement of this utility model is that the weighing module is connected to a data storage module, which is used to store the weight data of each weighing and the corresponding weighing time.

[0026] The weighing module is connected to the data storage module to store the weight data and corresponding time of each weighing, which facilitates data management and traceability in the production process, helps to analyze the use of materials in the production process, provides data support for production process optimization and quality control, improves the management efficiency and quality assurance level of bioproduct production, and facilitates comprehensive monitoring and management of the production process.

[0027] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0028] 1. Traditional manual handling and weighing is arduous, dangerous, and prone to causing personal injury. This invention replaces manual handling with a motor-driven system. Operators only need to operate the controller to easily lift and weigh the mobile tank, significantly reducing labor costs and safety risks. Furthermore, the casters at the bottom of the frame, equipped with brakes, allow for flexible movement while maintaining stable fixation during weighing, preventing equipment movement from affecting weighing or causing danger. The surrounding guardrails further prevent the mobile tank from swaying and colliding with surrounding objects, ensuring comprehensive production safety.

[0029] 2. This utility model employs a servo motor and controller to precisely control the rack and pinion lifting, ensuring smooth lifting of the moving tank and laying the foundation for accurate weighing. The pressure sensor within the weighing module is connected to the display screen, providing real-time and intuitive display of weight data, avoiding errors from manual readings. The data storage module also automatically records each weighing data point and time, facilitating subsequent traceability and analysis. Furthermore, an alarm promptly sounds when the weight exceeds the preset range, preventing overload damage to the equipment and ensuring the accuracy and intelligent management of the weighing process.

[0030] 3. This utility model adopts an adjustable hook, which can be adapted to mobile tanks of different specifications by simply rotating the adjustment knob. This eliminates the need for different equipment for various tanks, improving the equipment's versatility and efficiency. Meanwhile, the stainless steel frame with a passivated surface provides excellent corrosion resistance, meeting the stringent cleanliness requirements of biopharmaceutical production workshops. It is widely applicable to various biopharmaceutical production scenarios, reducing equipment procurement and maintenance costs for enterprises. Attached Figure Description

[0035] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0036] Please refer to the attached document. Figure 1 and 2 The following is a description of a specific embodiment: The mobile weighing device for biological product production of this utility model includes a frame 1. A motor 2 with a rack 3 is installed at the top of the frame 1. Referring to a rack motor or rack-driven motor, the rack 3 can move up and down with the rotation of the motor 2. A weighing module 4 is suspended below the rack 3. A hook is installed below the weighing module 4. The weighing module 4 is connected to a mobile tank 5 through the hook. Wheels 6 are installed at the bottom of the frame 1, which can drive the frame 1 to move freely.

[0037] In operation, motor 2 starts, driving rack 3 to move. Based on the gear and rack transmission principle, rack 3 moves up and down, thereby raising and lowering the suspended weighing module 4 and the connected mobile tank 5. Wheels 6 at the bottom of frame 1 allow frame 1 to move freely, flexibly approaching the mobile tank 5 for weighing operations. This structural design achieves mobility of the weighing device, overcoming the limitations of fixed weighing equipment. It facilitates weighing the mobile tank 5 at different locations within the biopharmaceutical production workshop, effectively improving weighing convenience and reducing transportation costs and time consumption.

[0038] Specifically, motor 2 is a servo motor, which is connected to a controller 7. The controller 7 is fixed on the frame 1 and can control the rotation speed of the servo motor and the rotation angle of the motor shaft, thereby accurately controlling the lifting height of the rack 3.

[0039] When the weighing module 4 needs to be raised or lowered, the operator sends a command to the servo motor via the controller 7. The controller 7 precisely adjusts the rotation speed and shaft angle of the servo motor according to the command, thereby accurately controlling the raising and lowering height of the rack 3. Due to the high-precision control characteristics of the servo motor, compared to ordinary motors, it can more smoothly and accurately raise or lower the moving tank 5 to the appropriate position, avoiding collisions or shaking of the tank due to improper height control. This improves the stability and safety of the weighing process, ensures weighing accuracy, and reduces the risk of damage to equipment and materials.

[0040] Specifically, the frame 1 is made of stainless steel, and the surface of the stainless steel is passivated to improve its corrosion resistance and meet the cleanliness requirements of the bioproduct production workshop.

[0041] The frame 1 is made of stainless steel and has undergone passivation treatment. Stainless steel itself has a certain degree of corrosion resistance, and after passivation, a dense oxide film is formed on its surface, further improving its corrosion resistance. In biopharmaceutical production workshops, the humid environment containing chemicals can easily corrode equipment. This frame 1 effectively resists corrosion, maintains the integrity and stability of the equipment, and reduces equipment maintenance and replacement costs. At the same time, it meets the cleanliness requirements of the workshop, preventing impurities from contaminating biopharmaceuticals due to material corrosion, thus ensuring the quality and safety of the biopharmaceuticals.

[0042] Specifically, wheel 6 is a universal wheel equipped with a braking device, which can fix the position of frame 1 during weighing to prevent frame 1 from moving.

[0043] When the weighing device is moved to the side of the mobile tank 5 for weighing, the brake device is operated to fix the casters equipped with brakes, thereby stabilizing the position of the frame 1. During the weighing process, even if the mobile tank 5 shakes slightly, the fixed frame 1 ensures that the weighing module 4 operates stably, avoiding interference with the weighing results caused by the movement of the frame 1. This guarantees the accuracy and reliability of the weighing data and provides a stable measurement basis for the precise measurement of materials in biopharmaceutical production.

[0044] In one embodiment, a pressure sensor is installed inside the weighing module 4. The pressure sensor is connected to a display screen, which is mounted on the controller 7 to display the weight data of the moving tank 5 in real time.

[0045] During the weighing process, the weight of the moving tank 5 acts on the weighing module 4, and its internal pressure sensor converts the pressure signal into an electrical signal. These signals are transmitted to a connected display screen, which is mounted on the controller 7 and displays the weight data of the moving tank 5 in real time. Operators can directly obtain weight information while operating the controller 7, eliminating the need for additional readings. This reduces potential errors from manual readings, improves weighing efficiency, and makes the entire weighing process more convenient and efficient, providing reliable data support for material measurement in the biopharmaceutical production process.

[0046] In one embodiment, the frame 1 is surrounded by a protective railing to prevent the tank 5 from colliding with surrounding objects when it shakes during the weighing process.

[0047] When the mobile tank 5 is lifted for weighing, it may sway due to the lifting operation or its own imbalance. The guardrails installed around the frame 1 can prevent the swaying mobile tank 5 from colliding with surrounding equipment, facilities, or personnel. This not only protects the safety of other items and equipment in the workshop and avoids damage to production caused by collisions, but also ensures the personal safety of operators, creates a safe production environment, and reduces the probability of production accidents.

[0048] In one embodiment, the hook is an adjustable hook with an adjustment knob that can be used to adjust the opening size of the hook to accommodate mobile tanks 5 of different sizes.

[0049] When dealing with mobile tanks 5 of different sizes, the opening size of the hook can be changed by rotating the adjustment knob on the hook. This allows the weighing device to be adapted to various mobile tanks 5, eliminating the need to replace the entire weighing equipment for different tanks, thus improving the equipment's versatility and efficiency. Enterprises can use the same weighing device to meet different production needs, reducing equipment procurement costs and enhancing the device's applicability in biopharmaceutical production.

[0050] In one embodiment, the weighing module 4 is connected to the rack 3 via a shock-absorbing device, which reduces the impact of vibrations generated during the lifting and lowering of the moving tank 5 on the weighing results.

[0051] Vibrations occur during the lifting and lowering of the mobile tank 5, which may affect the measurement accuracy of the weighing module 4. The shock-absorbing device connecting the weighing module 4 and the rack 3 absorbs and buffers these vibrations. By reducing the interference of vibration on the weighing results, the accuracy and stability of the weighing data are ensured, allowing the weighing results to more accurately reflect the actual weight of the mobile tank 5, and providing more reliable data for material proportioning and other processes in biopharmaceutical production.

[0052] In one embodiment, an alarm is installed on the frame 1 and is connected to the weighing module 4. When the weight measured by the weighing module 4 exceeds the preset safe weight range, the alarm sounds.

[0053] The weighing module 4 continuously measures the weight of the moving tank 5 and transmits the data to the connected alarm. A safe weight range is pre-set in the alarm or related system; when the weight measured by the weighing module 4 exceeds this range, the alarm immediately sounds. This function promptly alerts operators, preventing equipment damage or accidents due to overloading, ensuring the safety of equipment and personnel, improving the safety and reliability of the weighing process, and ensuring the smooth operation of the bioproduct production process.

[0054] In one embodiment, the weighing module 4 is connected to a data storage module, which is used to store the weight data of each weighing and the corresponding weighing time.

[0055] After each weighing, the weighing module 4 transmits the measured weight data and the corresponding weighing time to the connected data storage module. This data is stored for easy retrieval and analysis later. By analyzing historical weighing data, companies can understand material usage, production process stability, and other information, providing strong data support for production process optimization, cost control, and quality traceability, thus helping to improve the management level and production efficiency of biopharmaceutical production.

[0056] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
