Abstract
Description
Technical Field
[0001] This utility model relates to an online detection and alarm device, and more particularly to an online detection and alarm device for the net content of bottled liquid beverages, belonging to the technical field of design and manufacturing equipment for beverage packaging production processes. Background Technology
[0002] In large-scale baijiu bottling production, the mainstream method for net content testing is still manual sampling and inspection. This involves inspectors randomly selecting a small amount of pre-bottled baijiu from the bottling line and weighing it to determine if the net content meets the standards. This sampling method for determining net content has several key problems: 1) Poor sampling representativeness and high risk of missed detection: Manual sampling can only cover a very small proportion of products and cannot cover products at different times and different filling stations in the production line. It is easy for unqualified products to be missed due to sampling deviation. Especially when the filling equipment experiences a sudden accuracy deviation, a large number of unqualified products will flow into the subsequent stages.
[0003] 2) High labor costs and high material losses: On the one hand, dedicated inspection personnel are required to continuously monitor sampling and operation testing, which increases labor costs; on the other hand, the samples after sampling are contaminated during the testing process and cannot be reused in the downstream production process, and can only be scrapped, resulting in additional losses of liquor raw materials and packaging materials, which significantly increases the company's production costs.
[0004] 3) The accuracy of the test is greatly affected by subjective factors: manual testing relies on the operator's sense of responsibility and standard of operation. Subjective factors have strong interference, making it difficult to guarantee the accuracy of the test results.
[0005] 4) Low detection efficiency: The net content of liquor is affected by the temperature and alcohol content of the liquor. Traditional manual detection requires manually measuring the weight and temperature of the bottled liquor, and then referring to a table to correct the measured net content value, which results in low detection efficiency. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide an online detection alarm device for the net content of bottled liquid beverages that has high detection efficiency, no missed detections, and guarantees the net content.
[0007] The technical solution adopted to solve the above-mentioned technical problems is: an online detection and alarm device for the net content of bottled liquid beverages, including a filling system. The online detection and alarm device also includes an identification and conveying mechanism, an online weighing mechanism, and a warning control system. The data lines of the filling system, the identification and conveying mechanism, and the online weighing mechanism are all connected to the warning control system simultaneously. During the liquid beverage filling process, each dispensing bottle is identified by the identification and conveying mechanism and sent into and out of the filling system. The net content of the liquid beverage injected into the dispensing bottle is weighed by the online weighing mechanism. If the net content of the liquid beverage exceeds the specified range, the warning control system, with the cooperation of the identification and conveying mechanism, identifies the bottle and issues a warning signal.
[0008] Furthermore, since the liquid beverage is baijiu (Chinese liquor), platinum resistance temperature sensors are installed on the baijiu storage tanks in the bottling system, and the data lines of the platinum resistance temperature sensors are connected to the warning control system.
[0009] The preferred embodiment of the above scheme is that the labeling and conveying mechanism includes a front labeling and conveying component and a rear labeling and conveying component. The dispensing bottles to be filled are labeled by the front labeling and conveying component and then sent to the online weighing mechanism to weigh the empty bottles. After the dispensing bottles are filled with liquid beverages, they are identified by the rear labeling and conveying component and then sent to the online weighing mechanism to weigh the injected liquid beverages.
[0010] Furthermore, the front-end labeling and conveying assembly includes a front-end clamping conveyor belt, a laser coder, and a front-end code recognition device. The laser coder and the front-end code recognition device are arranged in mutually compatible positions below the front-end clamping conveyor belt. During the process of the empty dispensing bottles to be filled being suspended and conveyed to the online weighing mechanism by the front-end clamping conveyor belt, a unique identification code is marked on the bottom of the bottles with the assistance of the laser coder, and the code is read and stored in the warning control system by the front-end code recognition device.
[0011] The preferred embodiment of the above scheme is that the rear identification and conveying component includes a rear clamping conveyor belt and a rear coding identifier, with the rear coding identifier positioned below the rear clamping conveyor belt. During the process of conveying the dispensing bottles after filling with liquid beverages to the online weighing mechanism via the rear clamping conveyor belt while being suspended in the air, the rear coding identifier reads the identification code and stores it in the warning control system.
[0012] Furthermore, the front-end coding and recognition device consists of a front-end coding and recognition camera, and the back-end coding and recognition device consists of a back-end coding and recognition camera.
[0013] The preferred embodiment of the above scheme is that the online weighing mechanism includes a front-end online weighing component and a rear-end online weighing component. The weight of the empty dispensing bottles to be filled, after being coded and identified, is weighed by the front-end online weighing component and stored in the warning control system. After the dispensing bottles have been filled with liquid beverages, the total weight of the dispensing bottles and the injected liquid beverages is weighed by the rear-end online weighing component and stored in the warning control system.
[0014] Furthermore, the pre-positioned online weighing component includes a pre-positioned online weighing machine and a conveyor belt. The conveyor belt is arranged on the pre-positioned online weighing machine. The empty bottles to be filled are weighed by the pre-positioned online weighing machine and the weight is stored in the warning control system. After being weighed, the empty bottles are transported to the filling system with the help of the conveyor belt.
[0015] The preferred embodiment of the above scheme is that the post-online weighing component includes a post-online weighing machine and a conveyor belt. The conveyor belt is arranged on the post-online weighing machine. After the liquid beverage is filled and its identity is identified by scanning the code, the total weight of the bottle and the liquid beverage is weighed by the post-online weighing machine and stored in the warning control system. After the weight is measured, the bottle is output to the designated position with the help of the conveyor belt.
[0016] Furthermore, the warning control system includes an industrial controller, warning signal components, and a database module storing relevant parameters. At least the front-end clamping conveyor belt, front-end code recognition device, rear-end clamping conveyor belt, rear-end code recognition device, front-end online weighing machine, rear-end online weighing machine, industrial controller, and warning signal components are all connected to the database module. The warning signal components include an audible and visual alarm, an abnormal situation display screen, and a traceability terminal, all of which are connected to the database module.
[0017] The beneficial effects of this utility model are as follows: The technical solution provided in this application, based on the existing filling system, constructs an online detection and alarm device by adding an identification and conveying mechanism, an online weighing mechanism, and an alarm control system. The data lines of the filling system, the identification and conveying mechanism, and the online weighing mechanism are all simultaneously connected to the alarm control system. During the liquid beverage filling process, each dispensing bottle is identified by the identification and conveying mechanism and fed into and out of the filling system. The net content of the liquid beverage injected into the dispensing bottle is weighed by the online weighing mechanism. Dispensing bottles with a net content exceeding the specified range are identified by the alarm control system in conjunction with the identification and conveying mechanism, and an alarm signal is issued. This solves the technical problems of existing technologies that rely on manual sampling for detecting the net content in dispensing bottles, resulting in weak sampling representativeness, low detection efficiency, high cost due to environmental influences, high false negative rates, and low detection accuracy. Using the online detection and alarm device of this application, the net content of the liquid filled in each dispensing bottle is automatically completed online, ensuring that every bottle is tested, overcoming the defects of missed detection, and requiring minimal human intervention. This not only guarantees the quality of detection but also effectively improves detection efficiency and ensures the net content of each bottle. Furthermore, by assigning a code to each dispensing bottle, full-process traceability of the dispensing bottle can be achieved, and the net content can be automatically corrected based on temperature. This reduces labor and material costs and improves detection efficiency, which is of great significance for solving the shortcomings of traditional sampling inspection and improving the quality control level of liquor production.

[0020] like Figure 1This invention provides an online detection and alarm device for the net content of bottled liquid beverages, offering high detection efficiency, eliminating missed detections, and ensuring guaranteed net content. The online detection and alarm device includes a filling system 1, a labeling and conveying mechanism, an online weighing mechanism, and a warning control system. The data lines of the filling system, the labeling and conveying mechanism, and the online weighing mechanism are all simultaneously connected to the warning control system. During the liquid beverage filling process, each dispensing bottle 2 is identified by the labeling and conveying mechanism and fed into and out of the filling system. The net content of the liquid beverage injected into the dispensing bottle 2 is weighed by the online weighing mechanism. If the net content of the dispensing bottle 2 exceeds the specified range, the warning control system, in conjunction with the labeling and conveying mechanism, identifies the bottle and issues a warning signal. The technical solution provided in this application, based on the existing filling system, adds an identification and conveying mechanism, an online weighing mechanism, and an alarm control system to form the online detection and alarm device of this application. The data lines of the filling system, the identification and conveying mechanism, and the online weighing mechanism are all simultaneously connected to the alarm control system. During the liquid beverage filling process, each dispensing bottle is identified by the identification and conveying mechanism and sent into and out of the filling system. The net content of the liquid beverage in the dispensing bottle is weighed by the online weighing mechanism. Dispensing bottles with a net content exceeding the specified range are identified by the alarm control system in conjunction with the identification and conveying mechanism, and an alarm signal is issued. This solves the technical problems of existing technologies that rely on manual sampling for detecting the net content in dispensing bottles, resulting in poor sampling representativeness, low detection efficiency, high cost due to environmental influences, high false negative rates, and low detection accuracy. Using the online detection and alarm device of this application, the net content of the liquid filled in each dispensing bottle is automatically completed online, ensuring that every bottle is tested, overcoming the defects of missed detection, and requiring low manual intervention. This not only guarantees the quality of the test but also effectively improves the testing efficiency and ensures the net content of each bottle. Furthermore, by assigning a code to each dispensing bottle, full-process traceability of the dispensing bottle can be achieved, and the net content can be automatically corrected based on temperature, reducing labor and material costs and improving testing efficiency. This is of great significance for solving the shortcomings of traditional sampling inspection and improving the quality control level of liquor production. In the applicant's case, the liquid beverage in this application is liquor. A platinum resistance temperature sensor 4 is also installed on the liquor storage tank 3 of the filling system, and the data line of the platinum resistance temperature sensor 4 is connected to the alarm control system. Of course, the technical solution of this application can also be used for the detection of the net content of other bottled beverages.
[0021] Accordingly, considering the actual conditions of the bottling production site, and in order to simplify the structure of the online detection and alarm device of this application as much as possible while better adapting to existing bottling production lines, the identification and conveying mechanism of this application includes a front-end identification conveying component and a rear-end identification conveying component. The dispensing bottles 2 to be filled are labeled by the front-end identification conveying component and then sent to the online weighing mechanism to weigh the empty bottles. After being filled with liquid beverages, the dispensing bottles 2 are identified by the rear-end identification conveying component and then sent to the online weighing mechanism to weigh the injected liquid beverage. The online weighing mechanism of this application includes a front-end online weighing component and a rear-end online weighing component. The empty dispensing bottles to be filled, after being labeled and identified, are weighed by the front-end online weighing component and the weight is stored in the warning control system. After being filled with liquid beverages, the dispensing bottles 2 are weighed by the rear-end online weighing component to weigh the total weight of the dispensing bottles 2 and the injected liquid beverage and the weight is stored in the warning control system. The warning control system of this application includes an industrial controller 13, a warning signal component 14, and a database module 15 storing relevant parameters. At least the front clamping conveyor belt 5, the front coding recognition device 6, the rear clamping conveyor belt 8, the rear coding recognition device 9, the front online weighing machine 10, the rear online weighing machine 12, the industrial controller 13, and the warning signal component 14 are all connected to the database module 15.
[0022] More specifically, the front-end labeling and conveying assembly includes a front-end clamping conveyor belt 5, a laser code assigner 6, and a front-end code reader 7. The laser code assigner 6 and the front-end code reader 7 are arranged adaptively below the front-end clamping conveyor belt 5. During the process of the empty dispensing bottles to be filled being suspended and conveyed to the online weighing mechanism via the front-end clamping conveyor belt 5, a unique identification code is marked on its bottom with the assistance of the laser code assigner 6, and this code is read and stored in the warning control system by the front-end code reader 7.

After weighing, the dispensing bottles 2 are output to the designated position with the assistance of the conveyor belt 11.
[0023] Furthermore, considering the current state of the technology, the front-end code recognition device 7 of this application consists of a front-end code recognition camera, and the back-end code recognition device 9 consists of a back-end code recognition camera. The warning signal component 14 of this application includes an audible and visual alarm, an abnormal situation display screen, and a traceability terminal, all of which are connected to the database module 15.
[0024] The technical solution of this application will be further described below through specific embodiments: In large-scale baijiu bottling production, net content accuracy is a core indicator for ensuring product compliance and protecting consumer rights. Traditional manual sampling and inspection methods suffer from poor sample representativeness, high risk of missed detection, high labor and material costs, and low testing efficiency, making it difficult to meet the demands of modern production for precise and efficient net content testing. Therefore, designing an online detection and alarm device that enables full-process traceability of glass bottles, automatically corrects net content based on temperature, reduces labor and material costs, and improves testing efficiency is of great significance for addressing the shortcomings of traditional sampling and inspection and improving the quality control level of baijiu production.
[0025] The purpose of this invention is to provide an online detection and alarm device that enables full-process traceability of glass bottles, accurate detection of the net content of liquor, and automatic alarm, thereby solving many problems associated with traditional manual sampling inspection. To achieve the above objective, this invention adopts the following technical solution, and the main components of the system are as follows: The main components of the system include: a glass bottle coding mechanism, a front-end online weighing machine, a temperature sensor, a rear-end glass bottle scanning mechanism, a rear-end online weighing machine, a control mechanism, and an alarm mechanism.
[0026] 1) Bottle Coding Mechanism: Located in the empty bottle conveying section of the filling line, it includes a first clamping conveyor belt, a laser coder, and a first coding recognition camera. The first clamping conveyor belt is used to suspend and transport empty bottles; the laser coder is located below the clamping conveyor belt and can engrave a unique identification code (such as a QR code or barcode) on the bottom of the empty glass bottle to record basic information about the bottle; the first coding recognition camera is connected to the control mechanism to collect identification code information and transmit it to the control mechanism to establish an independent traceability file for each glass bottle.
[0027] 2) Front-mounted online weighing machine: Located downstream of the glass bottle coding mechanism and upstream of the filling machine, it is used to collect the actual weight of the empty glass bottles and transmit it to the control mechanism, and bind and store the identification code of the coding recognition camera.
[0028] 3) Temperature sensor: Installed in the liquid storage tank of the filling machine, it adopts a platinum resistance temperature sensor with a temperature measurement range of 0-100℃ and an accuracy class of ±0.1℃. It is used to monitor the filling temperature in real time and transmit the temperature data to the control mechanism for subsequent net content correction calculation (to compensate for the influence of thermal expansion and contraction of the wine on the weight).
[0029] 4) Rear-mounted glass bottle scanning mechanism: Located downstream of the filling machine, it includes a second clamping conveyor belt and a second coding recognition camera. The second clamping conveyor belt suspends and transports the filled glass bottles; the second coding recognition camera is located below the second clamping conveyor belt and connected to the control mechanism. It is used to collect the identification code information of the filled glass bottles and transmit it to the control mechanism 6 to establish a traceability file for the filled glass bottles, ensuring that the total weight data and the empty bottle weight belong to the same glass bottle.
[0030] 5) Rear online weighing machine: Located downstream of the rear glass bottle scanning mechanism, it is used to collect the total weight of the glass bottles (containing wine) after filling, transmit it to the control mechanism, and bind it to the identification code of the corresponding glass bottle.
[0031] 6) Control Mechanism: Includes an industrial controller and a database module. The database module pre-stores the density values, net content standard weight ranges, and temperature correction values for different alcohol contents of baijiu at standard temperatures (e.g., 20℃). After receiving the identification code, empty bottle weight, liquor temperature, and total weight data, the industrial controller first calculates "actual liquor weight = total weight - empty bottle weight," then automatically calculates the corrected acceptable range value based on the current liquor temperature, and compares the actual liquor weight with this acceptable range value. 7) Alarm mechanism: including audible and visual alarm and display screen. When the control mechanism determines that the corrected net content exceeds the standard range, the audible and visual alarm will immediately emit a red warning light and a buzzer signal; the display screen will show the identification code of the abnormal glass bottle, the weight of the empty bottle, the total weight, and the measured net content value in real time.
[0032] Example 1 An online detection and alarm device for the net content of baijiu (Chinese liquor) mainly includes a glass bottle coding mechanism, a front-end online weighing machine, a temperature sensor, a rear-end glass bottle scanning mechanism, a rear-end online weighing machine, a control mechanism, and an alarm mechanism. The various mechanisms are connected by circuits or signal lines, enabling full-process traceability of glass bottles, accurate online detection of the net content of baijiu, and automatic alarm for abnormalities.
[0033] The glass bottle coding mechanism is set in the empty bottle conveying section of the filling line, including a first clamping conveyor belt, a laser coding device and a first coding recognition camera; the first clamping conveyor belt suspends and conveys the empty bottle, the laser coding device is located below the clamping conveyor belt and can engrave a unique identification code on the bottom of the empty glass bottle, and the first coding recognition camera is connected to the control mechanism to collect the identification code information and transmit it to the control mechanism.
[0034] The front-end online weighing machine is located downstream of the glass bottle coding mechanism and upstream of the filling machine. It is used to collect the actual weight of the empty glass bottles and transmit it to the control mechanism, where it is bound and stored with the identification code of the coding recognition camera.
[0035] The temperature sensor is installed inside the liquid storage tank of the filling machine. It is a platinum resistance temperature sensor with a temperature measurement range of 0-100℃ and an accuracy class of ±0.1℃. It is used to monitor the filling temperature in real time and transmit the temperature data to the control mechanism.
[0036] The rear-mounted glass bottle scanning mechanism is located downstream of the filling machine and includes a second clamping conveyor belt and a second coding recognition camera. The second clamping conveyor belt suspends and transports the filled glass bottles in the air, and the second coding recognition camera is located below the second clamping conveyor belt and connected to the control mechanism to collect the identification code information of the filled glass bottles and transmit it to the control mechanism.
[0037] The rear-mounted online weighing machine is located downstream of the rear-mounted glass bottle scanning mechanism. It is used to collect the total weight of the glass bottles (containing wine) after filling, transmit it to the control mechanism, and bind it to the identification code of the corresponding glass bottle.
[0038] The control mechanism includes an industrial controller and a database module; the database module pre-stores the density values, net content standard weight ranges, and temperature correction values of different alcohol contents of baijiu at standard temperatures; after receiving the relevant data, the industrial controller calculates the actual weight of the baijiu and compares it with the corrected acceptable range value.
[0039] The alarm system includes an audible and visual alarm, an abnormality display screen, and a traceability terminal. When the net content exceeds the standard range, the audible and visual alarm will issue a warning signal, the display screen will show information about the abnormal glass bottle, and the traceability terminal can query the entire process testing data of the glass bottle.
[0040] In summary, this application provides an online detection and alarm device for the net content of baijiu (Chinese liquor). It achieves full-process traceability through glass bottle coding, and combines dual weight acquisition and temperature correction to ensure the accuracy of net content detection. It also has an automatic alarm function, effectively solving the drawbacks of traditional manual sampling inspection, improving the quality control level of baijiu production, and reducing enterprise costs.
[0041] In implementing this utility model, firstly, the installation and connection of each mechanism are completed as required. The glass bottle coding mechanism is installed downstream of the empty bottle conveyor belt, the pre-mounted online weighing machine is installed between the coding mechanism and the filling station, the temperature sensor is installed in the filling machine's storage tank, and the rear glass bottle scanning mechanism and the rear online weighing machine are sequentially installed downstream of the filling station. The control mechanism and alarm mechanism are installed in appropriate locations in the workshop and connected to other mechanisms. Then, parameters such as the target net content, the corresponding weight table of liquor at different alcohol contents and temperatures, and the acceptable net content range are preset in the database module. During equipment operation, empty bottles are coded by the glass bottle coding mechanism and weighed by the pre-mounted online weighing machine before entering the filling station. During the filling process, the temperature sensor monitors the liquor temperature in real time. After filling, the glass bottles are scanned by the rear glass bottle scanning mechanism and weighed by the rear online weighing machine. The control mechanism calculates the actual liquor weight and compares it with the corrected acceptable range. If it is acceptable, it is conveyed normally; if it is unacceptable, the alarm mechanism is triggered. Workers can display abnormal glass bottle information on the screen to troubleshoot problems. This improves product quality and production safety.
