Description

Technical Field

[0001] The present invention relates to the field of cigarette manufacturing, and in particular to a tobacco flavoring and feeding self-inspection system and method. Background Art

[0002] Adding flavoring materials is an important process in cigarette production. The addition of flavoring materials plays a very important role in improving the sensory quality of cigarette products.

[0003] Currently, the flavoring and feeding process in the tobacco-making workshop primarily consists of five stages: on-site pipeline and valve inspection, liquid feed pipe delivery, liquid pre-filling, flavoring and feeding, and residual material recovery. Due to the complexity of tobacco leaves, liquid feed, pipeline valves, and on-site work, various problems are inevitable during the production process, such as pipeline and valve leaks, inadvertent liquid discharge, excessive liquid temperature, liquid-to-liquid cross-mixing, large fluctuations in feeding accuracy, and the inability to pre-fill.

[0004] If problems occur in the flavoring process, the resulting losses are enormous. At the very least, the flavoring liquid must be added or the tobacco leaves must be downgraded, or even the entire batch of tobacco leaves must be scrapped. Therefore, it is very important in the industry to conduct self-inspections of the flavoring process in order to monitor the entire flavoring production process. Summary of the Invention

[0005] In view of the above, the present invention aims to provide a tobacco flavoring and feeding self-detection system and method to solve the above-mentioned technical problems.

[0006] The technical solution adopted in the present invention is as follows:

[0007] The present invention provides a tobacco flavoring and feeding self-inspection system, comprising: a main control computer, a data acquisition and output unit, a voice alarm device, and a self-inspection component for monitoring the status and handling problems of five corresponding stages of the flavoring and feeding process; wherein the self-inspection component comprises an on-site pipeline valve self-inspection module, a feed and liquid pipe delivery self-inspection module, a feed and liquid pre-filling self-inspection module, a flavoring and feeding process self-inspection module, and a residual material recovery monitoring module;

[0008] The self-test component transmits data to the main control computer through the data acquisition and output unit, and the main control computer is connected to the voice alarm device by electrical signals;

[0009] The data acquisition and output unit is used to transmit the collected signals of the self-test component to the main control computer, and send the instructions of the main control computer to the self-test component; and

[0010] The main control computer is used to trigger the voice alarm device to broadcast a warning voice.

[0011] In at least one possible implementation, the on-site pipeline valve self-test module includes: a valve status acquisition unit for acquiring a valve opening and closing operation status signal, a valve leakage detection unit for collecting a valve leakage or non-leakage signal, and a valve positioning unit used in conjunction with the valve leakage detection unit, wherein the valve positioning unit is used to respectively acquire position signals of the valve when it is leaking and when it is not leaking.

[0012] In at least one possible implementation, the liquid feed pipe self-inspection module includes: a material pipe connecting unit for controlling the feed access, a material tank pressure relief unit for relieving the pressure in the material tank when the feeding and blowing pipeline are completed, a material liquid weighing unit for detecting the weight of the received material liquid, and a material liquid temperature control unit for maintaining the temperature of the material liquid.

[0013] In at least one possible implementation, the liquid pre-filling self-test module includes: a pre-filling automatic exhaust unit for exhausting air in the pipeline, a pump motor detection unit for detecting the operating frequency of the pump motor, and a liquid pre-filling state detection unit.

[0014] In at least one possible implementation manner, the flavoring and feeding process self-checking module includes: a flavoring and feeding flow control unit and a flavoring and feeding pipeline pressure detection unit.

[0015] In at least one possible implementation, the residual material recovery monitoring module includes: a feeding pipeline blowing unit for blowing the feeding pipeline, a residual material weight recording unit for collecting residual material weight information, and a residual material recovery post-processing unit.

[0016] In at least one possible implementation, the residual material recovery post-processing unit includes: a discharge solenoid valve, a cleaning solenoid valve, a sewage discharge solenoid valve, a timer and a PLC.

[0017] Based on the above system solutions, the present invention also provides a tobacco flavoring and feeding self-test method, which includes a main control computer for the flavoring and feeding process triggering a self-test component to start running according to the following method after receiving a production instruction:

[0018] Step S1: The on-site pipeline valve self-test module detects the valve opening and closing operation and leakage status of the flavoring and feeding pipeline. When an abnormal state is detected and the valve position is obtained, the voice alarm device is triggered to output a warning voice; when the state is detected to be normal, the main control computer requests the flavoring and sugar material kitchen based on the input material liquid brand information;

[0019] Step S2: The liquid material pipe delivery self-inspection module compares the liquid material brand information input from the production site and the sugar material kitchen to see if they are consistent. If they are inconsistent, the voice alarm device is triggered to output a warning voice. If they are consistent, the feed pipe of the corresponding material tank is automatically connected to carry out liquid material pipe delivery. Furthermore, after the liquid material pipe delivery is completed, the feed pipe is sprayed while the pressure in the material tank is released. After the spraying is completed, the weight of the liquid material is compared. If the weight comparison is abnormal, the voice alarm device is triggered to output a warning voice. If the weight comparison is normal, the liquid material is heated and pre-filled.

[0020] Step S3, the liquid pre-filling self-test module discharges the air in the feeding pipeline through the real-time detection data of the pipeline air detection device and the mass flow meter; and detects the real-time operating frequency and real-time mass flow of the material pump motor. If the real-time mass flow is insufficient, the main control computer controls the material pump motor through the frequency converter to adjust it. After the adjustment is normal, the flavoring and feeding operation is carried out. If the adjustment is abnormal, the voice alarm device is triggered to output a warning voice.

[0021] Step S4: The flavoring and feeding process self-checking module detects the mass flow rate, cumulative amount and flavoring and feeding pipeline pressure of the flavoring and feeding process in real time. If abnormal, the voice alarm device is triggered to output a warning voice;

[0022] Step S5: After the flavoring and feeding operations are completed, the residual material recovery monitoring module sprays the flavoring and feeding pipeline so that all the liquid in the pipeline is sprayed into the material tank; and after the spraying is completed, the quality of the residual material is collected and recorded; and after the residual material is counted, the residual material in the tank is recovered and processed.

[0023] In at least one possible implementation, step S4 further includes: if the pipeline pressure is abnormal, and the fluctuation of the flavoring and feeding mass flow and / or cumulative amount exceeds a preset range, the main control computer triggers a shutdown.

[0024] In at least one possible implementation, the post-recovery processing includes:

[0025] Open the discharge solenoid valve to discharge the residual material into the preset residual material recovery device;

[0026] After the remaining material is drained, close the discharge solenoid valve and open the cleaning solenoid valve according to the set time to clean the tank;

[0027] After the timing is over, open the sewage discharge solenoid valve to discharge the sewage, and then close the sewage discharge solenoid valve.

[0028] The main design concept of the present invention is to perform self-inspection on the five stages of the flavoring and feeding process through the main control computer of the flavoring and feeding, the data acquisition and receiving unit, and the self-inspection component. Specifically, it is mainly composed of the on-site pipeline valve self-inspection module, the material and liquid pipe delivery self-inspection module, the material and liquid pre-filling self-inspection module, the flavoring and feeding process self-inspection module and the residual material recovery monitoring module, which are used to detect and deal with problems in the entire process of flavoring and feeding. The introduction of the voice alarm device can assist the self-inspection component in manual intervention, thereby improving the efficiency and effectiveness of problem solving. While improving the level of automation, the present invention effectively reduces the number of failures in the flavoring and feeding process, ensuring process quality and production continuity. This eliminates the problem of equipment shutdown caused by inadequate inspection due to relying solely on manual inspection. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 2 This is a schematic diagram of the main process of the tobacco flavoring and feeding self-test method provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] The present invention proposes an embodiment of a tobacco flavoring and adding material self-test system, specifically, as Figure 1 As shown, it includes: a main control computer, a data acquisition and output unit, a voice alarm device and a self-test component; wherein the self-test component is composed of an on-site pipeline valve self-test module, a material and liquid pipeline self-test module, a material and liquid pre-filling self-test module, a flavoring and feeding process self-test module and a residual material recovery monitoring module, which is used to monitor the status of the five corresponding stages of the flavoring and feeding process and deal with problems;

[0034] The self-test component transmits data to the main control computer through the data acquisition and output unit, and the main control computer is connected to the voice alarm device by electrical signals;

[0035] The data acquisition and output unit is used to transmit the collected signals of the self-test component to the main control computer, and send the instructions of the main control computer to the self-test component to implement the self-test and processing actions of the self-test component; and

[0036] The main control computer can accurately broadcast abnormalities detected by the self-test component through the voice alarm device, thereby reminding on-site personnel to quickly troubleshoot and resolve the problem. In other words, this embodiment does not exclude human intervention, but only emphasizes that when the self-test component detects a problem at a certain stage of the process, it will primarily handle it independently. If the self-test component cannot handle the problem or the problem persists after self-treatment, the voice alarm device can be used to remind on-site personnel to manually handle it.

[0037] In some other embodiments, the main control computer can also be used to receive production instructions, obtain production status information, obtain flavoring and adding equipment working status information and obtain flavoring and sugar kitchen working status information, etc. In actual operation, the main control computer can be a terminal device in the control room, or it can be an industrial control computer placed on site, etc.

[0038] There are many options for implementing the self-test component. The following implementation examples are provided for reference:

[0039] (1) The on-site pipeline valve self-inspection module may specifically include: a valve status acquisition unit for acquiring a valve opening and closing operation status signal, a valve leakage detection unit for collecting a valve leakage signal, and a valve positioning unit used in conjunction with the valve leakage detection unit, wherein the valve positioning unit is used to respectively acquire a valve position signal when the valve is leaking and when there is no leakage.

[0040] Specifically, the valve state acquisition unit may refer to a valve limit switch, which collects the opening and closing state and action signal of the valve and transmits the detected valve state information to the data acquisition and output unit;

[0041] The valve leakage detection unit may include a compressed air source and an ultrasonic leak detector installed at the pipeline valve. When the compressed air source is triggered, the valve is filled with compressed air, and the ultrasonic leak detector is activated to determine whether the valve has a leakage problem, and then the detected valve leakage status signal is transmitted to the data acquisition and output unit;

[0042] The valve positioning unit may specifically include a first signal transceiver device and a second signal transceiver device; the first signal transceiver device is used to transmit and receive valve position information when it is detected that the valve is not leaking, and the second signal transceiver device is used to transmit and receive valve position information when it is detected that the valve is leaking. It can be understood that the valve position and leakage signals can be transmitted to the main control computer by the data acquisition and output unit.

[0043] In actual operation, before the valve positioning unit works normally, the valves to be tested can be numbered by type according to actual conditions. For example, two-position two-way valves can be numbered 2.2-01, 2.2-02, 2.2-03..., two-position three-way valves can be numbered 2.3-01, 2.3-02, 2.3-03... and so on.

[0044] (2) The liquid feed pipe self-inspection module may specifically include: a material pipe connecting unit for controlling the feed access, a material tank pressure relief unit for relieving the pressure in the material tank when the material feeding is completed and the spraying pipeline is blown, a material liquid weighing unit for detecting the weight of the received material liquid, and a material liquid temperature control unit for maintaining the temperature of the material liquid.

[0045] Specifically, the material pipe connecting unit is mainly used to automatically connect the feed pipe of the corresponding material tank. In other embodiments, the material liquid brand information input by the production site and the sugar material kitchen can be compared to implement error prevention processing before feeding. After the material liquid brand is correct, the feed pipe is triggered to connect. This is not limited to this embodiment.

[0046] The material tank pressure relief unit includes a pressure sensor, a pressure relief pipeline and a pressure relief solenoid valve. The pressure sensor is used to detect the pressure in the material tank in real time, and timely release the increased pressure in the material tank when the feeding and blowing pipeline are completed through the pressure relief pipeline and the pressure relief solenoid valve to avoid the problem of material liquid overflow due to excessive air pressure in the material tank;

[0047] The liquid weighing unit is used to collect the actual weight of the liquid received at the production site (a corresponding weight error tolerance range can be set, for example, the liquid weight received at the production site = the weight of the sugar material delivered from the kitchen ± 1 kg. Once this range is exceeded, it indicates that there is a problem with the liquid reception);

[0048] The liquid temperature control unit specifically includes a pulse frequency conversion heating control device, which controls high-temperature steam to reciprocately heat the liquid (mainly sugar), thereby controlling the sugar temperature within the required process temperature range (for example, the process temperature range is: the optimal operating temperature of the liquid ± 3°C);

[0049] The actions and detection information of the aforementioned units are transmitted to the main control computer through the data acquisition and output unit.

[0050] (3) The liquid pre-filling self-check module may specifically include: a pre-filling automatic exhaust unit for exhausting air in the pipeline, a pump motor detection unit for detecting the operating frequency of the pump motor, and a liquid pre-filling state detection unit.

[0051] Specifically, the pre-filling automatic exhaust unit mainly includes: a pipeline air detection device (such as an ultrasonic sensor), a mass flow meter and an exhaust solenoid valve, which detects in real time whether there is air in the pipeline during pre-filling and the real-time mass flow of the feeding pipeline, so as to automatically exhaust the air in the pipeline in time, thereby avoiding idling of the material pump, affecting the service life of the material pump and affecting the feeding accuracy;

[0052] The material pump motor detection unit can detect the operating frequency of the material pump motor in real time through the frequency converter. If the deviation between the actual operating frequency of the material pump motor and the set value does not conform to the preset error tolerance range, it indicates that there is a problem with the material pump operation (this error tolerance range can be set according to actual production);

[0053] The liquid pre-filling state detection unit can obtain the mass flow value of the liquid during the pre-filling process. If the measured value is greater than or equal to the preset pre-filling set value, it indicates that the pre-filling is normal, otherwise it indicates that it is abnormal.

[0054] The actions and detection information of the aforementioned units are transmitted to the main control computer through the data acquisition and output unit.

[0055] (4) The flavoring and feeding process self-check module may specifically include: a flavoring and feeding flow control unit and a flavoring and feeding pipeline pressure detection unit.

[0056] The flavoring and adding flow control unit mainly includes: a flow sensor and a feeding pump motor, which are used to collect the actual flow value of the flavoring and adding, and control the operating frequency of the feeding pump motor through a frequency converter to change the operating frequency, so as to adjust the size of the flavoring and adding mass flow when the actual flow rate does not meet the preset value. It can be supplemented here that the aforementioned flow sensor can also be used to obtain the actual cumulative amount of the flavoring and adding, and can perform error detection on the actual cumulative amount according to process requirements.

[0057] The pressure detection unit of the flavoring and feeding pipeline mainly includes a pressure sensor installed on the flavoring and feeding pipeline, which reads the real-time pressure value of the pipeline through the pressure sensor, so as to be used to detect whether the pressure of the flavoring and feeding pipeline is normal;

[0058] The actions and detection information of the aforementioned units are transmitted to the main control computer through the data acquisition and output unit.

[0059] (5) The residual material recovery monitoring module may include: a feeding pipeline blowing unit for blowing the feeding pipeline, a residual material weight recording unit for collecting residual material weight information, and a residual material recovery post-processing unit.

[0060] Among them, the discharge solenoid valve, cleaning solenoid valve, sewage solenoid valve, timer and PLC together constitute the residual material recovery post-processing unit. After the feeding is completed, after blowing and the residual material weight is collected, the discharge solenoid valve is opened by the PLC and kept open for the first time period set by the timer, and the residual material is discharged into the preset residual material recovery device. After that, the cleaning solenoid valve is opened and kept open for the second time period set by the timer to clean the material tank. Finally, the sewage solenoid valve is triggered to open and discharge the sewage. It can be understood that the aforementioned solenoid valves are connected to their corresponding pipelines.

[0061] The actions and detection information of the aforementioned units are transmitted to the main control computer through the data acquisition and output unit.

[0062] Based on the various embodiments of the above system, an embodiment of a tobacco flavoring and adding material self-test method is also provided. Figure 2 As shown, the main control computer for the flavoring and adding process triggers the self-test component to start running in the following manner after receiving the production instruction:

[0063] Step S1: The on-site pipeline valve self-test module detects the valve opening and closing operation and leakage status of the flavoring and feeding pipeline. When an abnormal status is detected and the valve position is obtained, the voice alarm device is triggered to output a warning voice to prompt on-site staff to deal with the abnormal valve that has been located. When the status is detected to be normal (it can be normal after self-test or normal after manual treatment and cyclic detection), the main control computer requests materials from the flavoring and sugar kitchen based on the input material liquid brand information.

[0064] The specific steps of valve leakage detection include: continuously introducing compressed air into the feeding pipeline, and using an ultrasonic leak detector installed at the pipeline valve to detect whether there is gas leakage, so as to determine whether the sealing of the pipeline valve is intact (due to the special nature of the feeding pipeline, it is inconvenient to use other liquids for testing, so compressed air testing is used. Another function of introducing compressed air is to spray the feeding pipeline to avoid residual liquid in the pipeline and the problem of liquid mixing).

[0065] Step S2: The liquid material pipe delivery self-check module compares the liquid material brand information input by the production site with that input by the sugar material kitchen to see if they are consistent. If they are inconsistent, the voice alarm device is triggered to output a warning voice to remind the on-site staff to confirm. If they are consistent, the feed pipe of the corresponding material tank is automatically connected to start liquid material pipe delivery.

[0066] After the liquid feed is completed, the feed pipeline is sprayed and the pressure in the tank is released to prevent the liquid from overflowing. After the spraying is completed, the weight of the liquid is compared. If the weight comparison is abnormal, the voice alarm device is triggered to output a warning voice to remind the on-site staff to check and replenish the material. If the weight comparison is normal, the liquid feed is heated and pre-filled. Specifically, the amount of high-temperature steam used can be estimated based on the weight of the liquid feed, and the liquid feed is heated back and forth to control the liquid feed temperature within the preset process temperature range.

[0067] Step S3, the liquid pre-filling self-test module uses the real-time detection data of the pipeline air detection device and the mass flow meter to promptly discharge the air in the feeding pipeline to prevent the feeding pump motor from idling and affecting the service life of the feeding pump and the feeding accuracy; and detects the real-time operating frequency and real-time mass flow of the feeding pump motor. If the real-time mass flow is insufficient, the main control computer controls the feeding pump motor through the frequency converter to make adjustments. After the adjustment is normal, the flavoring and feeding operation is carried out. If the adjustment is abnormal, the voice alarm device is triggered to output a warning voice to remind the on-site staff to perform manual processing.

[0068] Step S4: The flavoring and feeding process self-check module detects the mass flow, cumulative amount and flavoring and feeding pipeline pressure of the flavoring and feeding process in real time. If it is abnormal, the voice alarm device is triggered to output a warning voice to remind the on-site staff to conduct investigation and processing.

[0069] If only an abnormal mass flow or cumulative amount of the flavoring material is detected, the main control computer can control the material pump motor through the frequency converter to make adjustments. Abnormal pressure in the flavoring material pipeline is mostly caused by blockage in the flavoring material pipeline or filter. If the pipeline pressure is abnormal and the fluctuation of the flavoring material mass flow and / or cumulative amount exceeds the preset range, the main control computer will trigger a shutdown to clean the flavoring material pipeline and filter. (To ensure production continuity, the feeding pipeline and filter can be cleaned using an ultrasonic cleaning device during each production interval.) After the flavoring material production is completed, the remaining material is recycled.

[0070] Step S5, after the flavoring and feeding operations are completed, the flavoring and feeding pipeline is sprayed by the residual material recovery monitoring module, and all the liquid in the pipeline is sprayed into the material tank to avoid the mixing of liquid and material during brand change production; and after the spraying is completed, the quality of the residual material is collected and recorded, so as to facilitate the later statistical analysis of the liquid usage, liquid pre-filling and liquid loss in the flavoring and sugar material kitchen; and after the residual material is counted, the residual material in the tank is recovered and cleaned. Specifically, the recovery and cleaning treatment method includes: opening the discharge solenoid valve to discharge the residual material into a preset residual material recovery device; after the residual material is discharged, closing the discharge solenoid valve and opening the cleaning solenoid valve according to the set timing to clean the material tank; after the timing is over, opening the sewage solenoid valve to discharge the sewage, and then closing the sewage solenoid valve.

[0071] At this point, the self-inspection process of a batch production is completed. When the next batch production starts, the self-inspection process can be carried out according to the above self-inspection steps, thereby ensuring the normal production of the flavoring and feeding process.

[0072] In summary, the main design concept of the present invention is to perform self-inspection on the five stages of the flavoring and feeding process through the main control computer of the flavoring and feeding, the data acquisition and receiving unit and the self-inspection component. Specifically, it is mainly composed of the on-site pipeline valve self-inspection module, the material and liquid pipe self-inspection module, the material and liquid pre-filling self-inspection module, the flavoring and feeding process self-inspection module and the residual material recovery monitoring module, so as to detect and deal with problems in the complete process of flavoring and feeding. The introduction of the voice alarm device can assist the self-inspection component in manual intervention, thereby improving the efficiency and effect of problem solving. While improving the level of automation, the present invention effectively reduces the number of failures in the flavoring and feeding process, and ensures the process quality and production continuity. This eliminates the problem of equipment shutdown caused by inadequate inspection due to relying solely on manual inspection.

[0073] In the embodiment of the present invention, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent the existence of A alone, the existence of A and B at the same time, and the existence of B alone. A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" and similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can be represented by: a, b, c, a and b, a and c, b and c, or a, b and c, where a, b, c can be single or multiple.

[0074] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred modes can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
