Description

Technical Field

[0001] This utility model relates to the field of filling device technology, specifically a dual precision monitoring device for liquid formulation dosage. Background Technology

[0002] For the pharmaceutical industry, accurate control of filling volume is crucial. Overfilling not only reduces production yield and increases production costs, but for formulations with strict dosage requirements, it may also lead to patient overdose and cause serious safety risks. Underfilling, on the other hand, directly affects the efficacy of the drug, causing it to fail to meet quality standards and become a substandard product. This not only harms the interests of patients but also negatively impacts the reputation of the company.

[0003] Traditional methods of filling volume control primarily rely on the power source of the filling pump, adjusting the filling volume by controlling the opening and closing of valves. In actual filling processes, factors such as fluctuations in filling pump pressure and delays in valve response can easily cause significant fluctuations in the filling volume, making it difficult to guarantee stability and accuracy. Furthermore, traditional methods often cannot achieve real-time online monitoring of the filling volume of each vial, nor can they effectively monitor the differences in filling volume between different formulations within a batch. Quality control is often limited to post-production sampling inspections, which suffers from detection lag and cannot promptly identify and remove substandard products.

[0004] To address these issues, the industry urgently needs a device capable of accurately detecting the filling volume. Utility Model Content

[0005] The purpose of this invention is to provide a dual-precision monitoring device for liquid dosage forms. This device can simultaneously detect the liquid level and weight of the liquid dosage form during filling, determining whether the dosage of each vial is up to standard. This solves the technical problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual precision monitoring device for liquid dosage, characterized in that it includes a filling turntable, a dosage bottle, a grating emission source, a grating receiver, a weighing module, a lifting cylinder, an integrated display, and an alarm. The filling turntable has multiple stations for placing preparation bottles evenly distributed along the circumference. The filling turntable is connected to the drive mechanism and can rotate around its own central axis. The weighing module is fixed on the workbench and is used to weigh the preparation bottles; the filling turntable is located on the upper part of the weighing module. The lifting cylinder is fixed above the filling turntable by a bracket. Its piston rod is connected to the grating emission source and the grating receiver respectively by connectors. The lifting cylinder is equipped with a stroke sensor, which is electrically connected to the integrated display. The grating emission source is a vertical visible light emitter, which is arranged above the filling turntable opposite to the grating receiver. The integrated display is electrically connected to the control terminal of the lifting cylinder, the weighing module, the grating emitter, and the grating receiver, respectively.

[0007] Furthermore, the weighing module is equipped with several strain gauges, which are electrically connected to a signal amplifier, which is electrically connected to a processor. A cushioning pad made of elastic material is laid on top of the weighing module.

[0008] Furthermore, it also includes an alarm device installed on the integrated display; the alarm device is an audible and visual alarm device, which is electrically connected to the integrated display.

[0009] Furthermore, the integrated display is equipped with a data storage module and a communication module, and the communication module is connected to an external central control system.

[0010] Furthermore, the filling turntable is provided with several positioning seats, and the preparation bottle is positioned on the positioning seats.

[0011] Beneficial effects This invention employs a dual monitoring mechanism by simultaneously detecting weight and liquid level. Compared to traditional single-method filling control, this offers higher detection accuracy and can more accurately determine whether the dosage bottle's filling level is up to standard. Weight detection directly obtains the actual weight of the liquid, while liquid level detection reflects the filling level from the perspective of liquid height. The two complement and verify each other, effectively avoiding errors that may occur with single-method detection and improving the reliability of filling level detection.

[0012] This invention enables real-time online detection of each formulation bottle, allowing for filling quantity determination during the filling process. Compared to traditional post-filling sampling inspection, this significantly shortens the inspection cycle, promptly identifies substandard products, prevents them from entering subsequent processes or the market, and reduces quality risks.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To achieve the above objectives, this utility model provides the following technical solution, such as... Figure 1-2 As shown, a dual precision monitoring device for liquid dosage includes a filling turntable 5, a dosage bottle 6, a grating emitter 1, a grating receiver 2, a weighing module 3, a lifting cylinder 4, an integrated display 7, and an alarm 8. The filling turntable 5 has three stations evenly distributed along its circumference for placing the preparation bottles 6, including station one, station two, and station three. The preparation bottles 6 are filled at station two. The filling turntable 5 is connected to the drive mechanism under the workbench via a transmission shaft, which penetrates the center of the weighing module 3. The filling turntable 5 is located on the upper part of the weighing module 3. The filling turntable 5 rotates around its own central axis, thereby moving the preparation bottles 6 between different stations. Weighing module 3 is fixed on the workbench; it is used to weigh the empty preparation bottle 6 at one workstation to automatically remove the tare weight, and to weigh the preparation bottle 6 after filling at three workstations to obtain the weight of the medicine liquid. The grating emitter 1 is a vertically arranged visible light emitter, which is positioned above the filling turntable 5 opposite to the grating receiver 2. The grating emitter 1 can emit light to form a visible light grating. The grating receiver 2 is positioned corresponding to the grating emitter 1 and is used to receive the light source emitted by the grating emitter 1. When there is no obstruction, the grating will be completely received. When there is liquid obstruction, for transparent liquids, the light source below the surface can be received by the grating receiver 2 through the liquid. Since the transmittance of the liquid surface is much different from that of the unlit areas below and above the liquid surface, the liquid level can be measured by the light transmission. For non-transparent liquids, the liquid level height is calculated by measuring the intensity of reflected or transmitted light.

[0018] The lifting cylinder 4 is fixed above the filling turntable 5 at station three by a bracket. Its piston rod is connected to the grating emitter 1 and the grating receiver 2 by connectors. The lifting cylinder 4 is equipped with a stroke sensor, which is electrically connected to the integrated display 7. The control end of the lifting cylinder 4 is electrically connected to the integrated display 7. The lifting cylinder 4 is used to drive the grating emitter 1 and the grating receiver 2 to move up and down in the vertical direction to approach the preparation bottle 6 at station three.

[0019] When performing volume detection on the preparation bottles 6 at the third workstation, the lifting cylinder 4 moves the grating emitter 1 and the grating receiver 2 closer to the preparation bottle 6, so that the grating can cover the preparation bottle 6. After the liquid level detection is completed, the lifting cylinder 4 moves the grating emitter 1 and the grating receiver 2 back to their original positions to avoid affecting the rotation of the filling turntable 5. The lifting cylinder 4 is equipped with a stroke sensor to detect the lifting stroke of the lifting cylinder 4 and transmit the stroke data to the integrated display 7. The integrated display 7 controls the start and stop of the lifting cylinder 4 according to the stroke data to ensure that the grating emitter 1 and the grating receiver 2 can accurately reach the detection position and improve the accuracy of liquid level detection.

[0020] The integrated display 7 is equipped with operation buttons and a touch screen, which are electrically connected to the weighing module 3 and the grating receiver 2, respectively. The integrated display 7 receives the weight data transmitted by the weighing module 3 and the liquid level data transmitted by the grating receiver 2, and converts and compares the weight data and liquid level data. It judges whether the filling volume of the preparation bottle 6 is qualified according to the preset filling volume qualification standard, and calculates and displays the filling volume difference between each preparation bottle 6. The integrated display 7 is equipped with operation buttons and a touch screen. The operator can input the parameters of the filling volume qualification standard and set the threshold for filling volume difference through the operation buttons or the touch screen. The touch screen can display information such as weight data, liquid level data, and the judgment result of filling volume qualification.

[0021] Furthermore, the weighing module 3 has several strain gauges inside the base plate that supports the preparation bottle 6. The strain gauges are electrically connected to the signal amplifier, the signal amplifier is electrically connected to the processor, and the processor of the weighing module 3 is electrically connected to the integrated display 7. When an external force is applied, the strain gauges will undergo slight deformation and generate a weak electrical signal to the signal amplifier. The weighing module 3 converts these electrical signals into digital signals and sends them to the processor to measure the weight of the preparation bottle 6. Furthermore, it also includes an alarm 8; the alarm 8 is an audible and visual alarm, which is located above the display 7. When the integrated display 7 determines that the filling volume of the preparation bottle 6 is not up to standard, the alarm 8 will issue an audible and visual alarm signal and at the same time control the filling equipment to automatically stop, waiting for the staff to adjust the filling volume.

[0022] Furthermore, the integrated display 7 is also electrically connected to a data storage module and a communication module. The communication module is connected to an external central control system. The data storage module is used to store information such as weight data, liquid level data, filling volume judgment results, and filling volume difference data received by the integrated display 7, so as to facilitate subsequent data retrieval by staff. The communication module is electrically connected to the integrated display 7 and can transmit the detection data and equipment operating status information of the integrated display 7 to the factory's central control system to realize remote monitoring of the equipment.

[0023] Furthermore, each station of the filling turntable 5 is equipped with a positioning seat, which is a semi-circular groove structure; the shape and size of the groove structure match the preparation bottle 6; the preparation bottle 6 is limited on the positioning seat. Correspondingly, the weighing module 3 is also equipped with an annular baffle; the baffle is coaxially arranged with the filling turntable 5; the preparation bottle 6 can be placed between the baffle and the groove structure of the filling turntable 5.

[0024] The working principle and process are as follows: First, the staff places the empty preparation bottle 6 on the positioning seat at one of the workstations of the filling turntable 5; the weighing module 3 at one of the workstations senses the weight of the preparation bottle 6, weighs it, and automatically uses this weight as the tare weight to zero, completing the tare operation, and at the same time transmits the tare signal to the integrated display 7.

[0025] Then, the filling turntable 5 rotates under the drive mechanism, transferring the peeled preparation bottle 6 to station two. The filling equipment fills the preparation bottle 6 at station two with the medicine. After filling is completed, the filling turntable 5 continues to rotate, transferring the filled preparation bottle 6 to station three.

[0026] Weighing modules 3 at workstation 3 weigh the filled preparation bottles 6, obtain the weight data of the liquid medicine, and transmit the weight data to the integrated display 7. At the same time, the integrated display 7 controls the lifting cylinder 4 to descend, which moves the grating emitter 1 and the grating receiver 2 to the position of the preparation bottle 6, so that the grating covers the preparation bottle 6. The grating emitter 1 emits a visible light grating, and the grating receiver 2 receives the grating signal and detects the liquid level data of the liquid medicine in the preparation bottle 6 according to the transmission or reflection of the grating, and transmits the liquid level data to the integrated display 7. The stroke sensor detects the stroke data of the lifting cylinder 4 in real time and transmits it to the integrated display 7.

[0027] Finally, after receiving the weight data and liquid level data, the integrated display 7 converts and compares the two types of data, and determines whether the filling volume of the preparation bottle 6 is qualified according to the preset filling volume qualification standards (such as weight range and liquid level height range). If the integrated display 7 determines that the filling volume of the preparation bottle 6 is not qualified, it controls the alarm 8 to issue an audible and visual alarm signal, and sends a stop signal to the filling equipment through the communication module, so that the filling equipment automatically stops and waits for the staff to adjust the filling volume parameters.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
