Description

Technical Field

[0001] This invention relates to the field of tobacco manufacturing technology, and in particular to a method and system for adjusting the amount of stems removed. Background Technology

[0002] As a crucial global manufacturing sector, the tobacco industry's product quality stability and consistency directly impact a company's market competitiveness and brand image. In cigarette production, the stem and stalk content in the tobacco is a key factor affecting cigarette quality. The amount of stem and stalk removed not only determines the cigarette's appearance but also directly relates to the utilization efficiency of the tobacco raw materials and production costs. Insufficient removal leads to a higher cigarette puncture rate, affecting product appearance and consumer experience; excessive removal results in tobacco waste and increases production costs. Therefore, precisely controlling the amount of stem and stalk removed to ensure it remains within the reasonable range required by the manufacturing process has always been a core technical issue for tobacco manufacturers.

[0003] Currently, most cigarette rolling machines still rely primarily on manual operation for measuring and adjusting the amount of stems and twigs removed during production. Specifically, operators periodically sample the removed stems and twigs from the production line, weigh them, and judge based on experience whether adjustments to relevant machine parameters are necessary. This manual intervention model has several inherent drawbacks: First, the measurement cycle is long, making continuous monitoring impossible and resulting in a significant delay in responding to fluctuations in the removal rate; second, manual sampling and weighing processes are prone to introducing errors, making it difficult to guarantee the accuracy of measurement results; furthermore, operators rely on experience for adjustments, lacking unified and objective judgment standards, which can easily lead to inconsistent adjustments due to individual differences, further affecting the stability of product quality.

[0004] The aforementioned problems make it difficult to strictly control the amount of stems and twigs removed during actual production within the required process range. On the one hand, insufficient removal leads to residual stems and twigs in the cigarettes, causing problems such as cigarette punctures and poor appearance; on the other hand, excessive removal means wasting usable tobacco, directly increasing raw material costs. Furthermore, manual control methods are ill-suited to the high-speed, continuous production pace and cannot respond quickly and accurately to real-time changes caused by factors such as raw material variations, equipment wear and tear, or environmental fluctuations during production, severely restricting product quality consistency and production efficiency.

[0005] With the continuous advancement of tobacco production technology and the sustained expansion of production scale, cigarette production systems are rapidly developing towards automation and intelligence. However, the existing stem removal quantity control process has a low degree of automation and is difficult to effectively integrate with modern production management systems. This technological mismatch limits the further development of enterprises in improving product quality, reducing production costs, and increasing overall production efficiency. Therefore, the industry urgently needs a technical solution that can automatically monitor and adjust the stem removal quantity in real time to overcome the limitations of manual operation and meet the demands of high-level automated production. Summary of the Invention

[0006] The purpose of this invention is to provide a method and system for adjusting the amount of stem removal, so as to achieve precise real-time adjustment of the amount of stem removal.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A method for adjusting the amount of stems removed by a cigarette rolling machine, used to adjust the amount of stems removed per unit time, comprising the following steps:

[0009] S10: Set a sampling time, receive the stems and twigs removed by the cigarette machine within the sampling time, and weigh them to obtain the actual amount of stems and twigs removed.

[0010] S20: Obtain the process quality requirement value and calculate the difference between the actual amount of stems and twigs removed and the process quality requirement value;

[0011] S30: Determine whether the difference between the actual amount of stems removed and the required process quality value is within a preset range. If not, proceed to S40; if yes, proceed directly to S50.

[0012] S40: Adjust the air intake of the cigarette machine according to the difference between the actual amount of stems removed and the required process quality value;

[0013] S50: After weighing, the sticky tag is discharged, and after an interval, S10 is repeated.

[0014] As an optional technical solution for adjusting the amount of stems removed, adjusting the air intake of the cigarette machine includes: reducing the air intake of the cigarette machine when the actual amount of stems removed is greater than the process quality requirement value; and increasing the air intake of the cigarette machine when the actual amount of stems removed is less than the process quality requirement value.

[0015] As an optional technical solution for adjusting the amount of scabs removed, the sampling time is set to 0.9 minutes to 1.1 minutes.

[0016] As an optional technical solution for adjusting the amount of scabs removed, the interval time is set to 30 to 60 minutes.

[0017] As an optional technical solution for adjusting the amount of stem removal, when the sampling time is T minutes, the required process quality value is 145T grams, and the preset range is -45T grams to 45T grams.

[0018] A stem removal amount adjustment system, applied to the aforementioned stem removal amount adjustment method, includes a sampling device, a weighing device, and a stem discharge pipe. The sampling device receives the stems removed by the cigarette machine and selectively transports them to the weighing device or the stem discharge pipe. The weighing device weighs the stems entering the weighing device to obtain the actual stem removal amount. The stem discharge pipe receives the stems output from the sampling device and the weighing device and discharges the stems from the stem removal amount adjustment system.

[0019] As an optional technical solution for the stem removal amount adjustment system, the stem removal amount adjustment system further includes an air intake adjustment device and a control component. The air intake adjustment device is communicatively connected to the cigarette machine. The control component is communicatively connected to the sampling device, the weighing device and the air intake adjustment device, respectively. The control component is used to increase or decrease the air intake of the cigarette machine according to the actual stem removal amount.

[0020] As an optional technical solution for the stem removal volume adjustment system, the cigarette machine is equipped with a blower for providing airflow; the air intake volume adjustment device includes a cigarette machine wall panel and an air intake volume adjustment plate rotatably connected to the cigarette machine wall panel. The air intake volume adjustment plate is used to guide the airflow, and the control component can adjust the opening of the air intake volume adjustment plate so that the air intake volume adjustment plate swings relative to the blower to increase or decrease the air intake volume of the cigarette machine.

[0021] As an optional technical solution for the stem removal amount adjustment system, the stem removal amount adjustment system also includes a stem removal device, which is connected to the output end of the weighing device and is used to transport the weighed stems to the stem removal pipe.

[0022] As an optional technical solution for the stem removal volume adjustment system, the weighing device includes a collection box and a weighing sensor. The collection box is installed on the weighing sensor and is used to receive the stems delivered by the sampling device. The weighing sensor is used to weigh the stems in the collection box.

[0023] The beneficial effects of this invention are:

[0024] This method for adjusting the amount of stems removed through automated sampling, weighing, difference calculation, judgment adjustment, and stem removal steps enables cyclical measurement and real-time adjustment of the stem removal amount. It overcomes the problems of long measurement cycles, inaccuracies, and lag in manual measurement, enabling real-time monitoring of the removal amount and comparison with process requirements, timely adjustment of the air intake, and ensuring that the stem removal amount remains within the required process quality range. Automatic control ensures that the stem removal amount consistently meets process quality requirements, effectively avoiding increased cigarette puncture rates due to insufficient removal or tobacco waste due to excessive removal, thus improving product quality stability and consistency. Simultaneously, this method can respond promptly to production changes, improving response speed, reducing human intervention, lowering production costs, and increasing production efficiency, providing a foundation for automated production in tobacco enterprises.

[0025] This stem removal quantity adjustment system constructs a complete automatic measurement framework, realizing the mechanization and automation of the entire stem removal process, replacing traditional manual operation, and significantly improving measurement efficiency and accuracy. Through automation, it solves the problems of inaccurate manual measurement and adjustment lag, laying the hardware foundation for real-time adjustment, while reducing labor intensity and improving the integration of the stem removal quantity adjustment system with existing cigarette machines. The overall structure of the stem removal quantity adjustment system is compact, enabling seamless integration with cigarette machines, improving measurement efficiency and control precision, providing hardware support for automatic adjustment, thereby reducing product quality risks and production costs.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figure 1 As shown, this invention provides a method for adjusting the amount of stems removed, used to adjust the amount of stems removed by a cigarette machine per unit time. The method for adjusting the amount of stems removed includes the following steps:

[0040] Step 1: Set the sampling time, receive the stems and twigs removed by the cigarette machine within the sampling time, and weigh them to obtain the actual amount of stems and twigs removed.

[0041] Step 2: Obtain the process quality requirement value and calculate the difference between the actual amount of stems and twigs removed and the process quality requirement value.

[0042] Step 3: Determine whether the difference between the actual amount of stems removed and the required process quality value is within the preset range. If not, proceed to Step 4; if yes, proceed directly to Step 5.

[0043] Step 4: Adjust the air intake of the cigarette machine according to the difference between the actual amount of stems removed and the required process quality.

[0044] Step 5: Remove the weighed skewer, and after an interval, repeat Step 1.

[0045] This method for adjusting the amount of stems removed through automated sampling, weighing, difference calculation, judgment adjustment, and stem removal steps enables cyclical measurement and real-time adjustment of the stem removal amount. It overcomes the problems of long measurement cycles, inaccuracies, and lag in manual measurement, enabling real-time monitoring of the removal amount and comparison with process requirements, timely adjustment of the air intake, and ensuring that the stem removal amount remains within the required process quality range. Automatic control ensures that the stem removal amount consistently meets process quality requirements, effectively avoiding increased cigarette puncture rates due to insufficient removal or tobacco waste due to excessive removal, thus improving product quality stability and consistency. Simultaneously, this method can respond promptly to production changes, improving response speed, reducing human intervention, lowering production costs, and increasing production efficiency, providing a foundation for automated production in tobacco enterprises.

[0046] Specifically, the process quality requirement value is set by the process quality department according to different cigarette machines, and can be adjusted as needed. The specific adjustment method is a conventional technical means in this embodiment, which is well mastered by those skilled in the art, and is not the focus of this embodiment, so it will not be elaborated here.

[0047] In this embodiment, adjusting the air intake of the cigarette machine includes: reducing the air intake of the cigarette machine when the actual amount of stems and twigs removed is greater than the required process quality value; and increasing the air intake of the cigarette machine when the actual amount of stems and twigs removed is less than the required process quality value.

[0048] By defining the specific logic for adjusting the air intake, precise adjustments are made based on the direction of the difference between the actual amount of cigarette residue rejected and the required process quality. This achieves simple, direct, and accurate feedback control. When the rejection amount deviates from the required value, it can respond quickly by reducing or increasing the air intake to rapidly bring the rejection amount back to the target range. This optimizes the rejection effect, enhances the precision and targeting of control, improves the accuracy and efficiency of adjustment, avoids over-adjustment or under-adjustment, and further ensures cigarette quality and cost control.

[0049] For example, the sampling time is set to 0.9 minutes to 1.1 minutes. Specifically, the sampling time is set to 1.0 minute.

[0050] This timeframe, validated through practice, ensures the rationality and consistency of the sampling time, making the measurement results representative and comparable. It balances sampling representativeness and response frequency, guaranteeing measurement accuracy and response speed. The shorter sampling time avoids the problem of long cycles in traditional manual measurements, ensuring the real-time nature of the measurement data while reducing random errors caused by excessively short sampling times, thus improving measurement accuracy and adjustment reliability. It also avoids the problems of large data fluctuations due to excessively short sampling times or the impact of excessively long sampling times on adjustment frequency, improving measurement accuracy and providing a reliable data foundation for subsequent adjustments.

[0051] In this embodiment, the interval time is set to 30 to 60 minutes.

[0052] This ensures a reasonable frequency of measurement and adjustment cycles. It avoids excessive adjustments that could lead to equipment wear or production interruptions, while also enabling timely monitoring and response to changes in the production process. This overcomes the lag inherent in manual adjustments, achieving stable and efficient continuous operation, making it suitable for continuous production environments and contributing to long-term cost reduction. Furthermore, regular monitoring of rejection rates maintains production process stability. This interval, matched to the production rhythm, ensures continuous quality control while reducing unnecessary equipment movements, thus improving lifespan and energy efficiency.

[0053] For example, when the sampling time is T minutes, the process quality requirement is 145T grams, with a preset range of -45T grams to 45T grams.

[0054] By linearly linking process quality requirements and preset ranges with sampling time, standardized quality thresholds and adjustment criteria are provided, enabling standard values ​​to adapt to different sampling conditions and enhancing flexibility and applicability. This dynamic threshold setting avoids the mismatch problem of fixed values ​​under different production conditions, improves judgment accuracy and flexibility, ensures scientific and reasonable adjustment logic, reduces misjudgments, and ensures precise adjustment under various production rhythms. Moreover, by quantifying the range, subjective judgment errors are avoided, ensuring the accuracy and consistency of adjustment and contributing to standardized product quality management.

[0055] like Figures 1 to 7 As shown, the present invention also provides a stem removal amount adjustment system, applied to the above-mentioned stem removal amount adjustment method. The stem removal amount adjustment system includes a sampling device 1, a weighing device 2, and a stem discharge pipe 18. The sampling device 1 is used to receive the stems removed by the cigarette machine and selectively transport them to the weighing device 2 or the stem discharge pipe 18. The weighing device 2 is used to weigh the stems entering the weighing device 2 to obtain the actual stem removal amount. The stem discharge pipe 18 is used to receive the stems output from the sampling device 1 and the weighing device 2 and discharge the stems from the stem removal amount adjustment system.

[0056] This stem removal quantity adjustment system constructs a complete automatic measurement framework, realizing the mechanization and automation of the entire stem removal process, replacing traditional manual operation, and significantly improving measurement efficiency and accuracy. Through automation, it solves the problems of inaccurate manual measurement and adjustment lag, laying the hardware foundation for real-time adjustment, while reducing labor intensity and improving the integration of the stem removal quantity adjustment system with existing cigarette machines. The overall structure of the stem removal quantity adjustment system is compact, enabling seamless integration with cigarette machines, improving measurement efficiency and control precision, providing hardware support for automatic adjustment, thereby reducing product quality risks and production costs.

[0057] In this embodiment, the cigarette rolling machine is taken as an example, specifically the ZJ116 type.

[0058] In this embodiment, the stem removal amount adjustment system also includes an air intake adjustment device 4 and a control component 5. The air intake adjustment device 4 is communicatively connected to the cigarette machine. The control component 5 is communicatively connected to the sampling device 1, the weighing device 2 and the air intake adjustment device 4 respectively. The control component 5 is used to increase or decrease the air intake of the cigarette machine according to the actual stem removal amount.

[0059] Control component 5 processes weighing data in real time based on the actual amount of stem and twig removal and drives the air intake adjustment device 4, achieving integrated automation of measurement, decision-making, and execution. This forms a closed-loop control system, significantly improving response speed and adjustment accuracy, and enabling real-time feedback and precise control. This helps to respond promptly to production fluctuations, enhances the intelligence level of the entire stem and twig removal adjustment system, ensures that the stem and twig removal amount dynamically remains within the process requirements, strengthens product quality stability, and fundamentally solves the quality risks and production cost problems caused by untimely manual adjustments.

[0060] Furthermore, the cigarette machine is equipped with a blower for providing airflow; the air intake adjustment device 4 includes a cigarette machine wall panel 41 and an air intake adjustment plate 46 rotatably connected to the cigarette machine wall panel 41. The air intake adjustment plate 46 is used to guide airflow, and the control component 5 can adjust the opening of the air intake adjustment plate 46 so that the air intake adjustment plate 46 swings relative to the blower to increase or decrease the air intake of the cigarette machine.

[0061] By specifying the structure of the air intake volume regulating device 4, precise opening control of the air intake volume regulating plate 46 is achieved, thereby guiding the airflow and adjusting the air intake volume. The specific structure is simple, reliable, and responsive, with good linear adjustment, making it easy to install and adjust on cigarette machines. Precise air intake volume control directly affects the stem and skewer removal effect, ensuring the reliability and repeatability of air intake volume adjustment, while reducing maintenance costs and enhancing the durability and control accuracy of the stem and skewer removal volume adjustment system.

[0062] In this embodiment, the stem removal amount adjustment system also includes a stem removal device 3, which is connected to the output end of the weighing device 2 and is used to transport the weighed stems to the stem removal pipe 18.

[0063] The stem removal device 3 automatically removes stems after weighing, preventing them from accumulating in the weighing device 2 and affecting weighing accuracy and continuous system operation, thus further optimizing production efficiency. It reduces the need for manual intervention, ensures seamless automation of the measurement cycle, improves the reliability and production efficiency of the stem removal adjustment system, and minimizes the need for manual intervention.

[0064] For example, the sampling device 1 includes a sampling funnel 13 and a sampling opening and closing plate 12 movably connected to the sampling funnel 13. The bottom of the sampling funnel 13 is provided with a recovery port, and the side of the sampling funnel 13 is provided with a material intake port. The sampling opening and closing plate 12 can move relative to the sampling funnel 13 between a sampling position and a working position. When the sampling opening and closing plate 12 is in the sampling position, the sampling opening and closing plate 12 guides the stalk in the sampling funnel 13 into the weighing device 2. When the sampling opening and closing plate 12 is in the working position, the stalk in the sampling funnel 13 falls into the recovery port and enters the stalk discharge pipe 18.

[0065] The selective conveying of stems and twigs (to the weighing device 2 or directly discharged) is achieved by moving the sampling opening and closing plate 12, enabling flexible switching between sampling and discharge. The ingenious structure and flexible operation ensure that the continuous production of the cigarette machine is not affected during sampling. This design ensures the representativeness of the sampling and the smoothness of the discharge, improves the accuracy of the measurement data, simplifies the operation process, reduces the risk of blockage, enhances the durability and maintainability of the stem and twig removal adjustment system, and reduces the failure rate.

[0066] In this embodiment, the sampling device 1 is further provided with a double-acting cylinder 11, a hopper 14, a frame 15, and a foot pad 17. The sampling device 1 is fixedly installed with the weighing device 2 and the stem removal device 3 via the frame 15. The foot pad 17 is located at the bottom of the frame 15 and is used to support the other components on the sampling device 1. The double-acting cylinder 11 is mounted on the frame 15, and the output end of the double-acting cylinder 11 is connected to the sampling opening and closing plate 12 to drive the sampling opening and closing plate 12 to slide. The sampling opening and closing plate 12 guides the stems passing through the sampling port to the hopper 14; the hopper 14 receives the stems guided by the sampling opening and closing plate 12 and conveys the stems to the weighing device 2.

[0067] For example, the weighing device 2 includes a collection box 21 and a weighing sensor 22. The collection box 21 is mounted on the weighing sensor 22 for receiving the skewer conveyed by the hopper 14; the weighing sensor 22 is mounted on the frame 15 for weighing the skewer in the collection box 21; and the digital display screen 23 is communicatively connected to the weighing sensor 22.

[0068] The weighing sensor 22 directly weighs the stalks in the collection box 21, replacing the traditional manual estimation or offline weighing method. This fundamentally eliminates human error, ensures the accuracy and objectivity of the actual stalk removal amount, and lays a reliable data foundation for subsequent precise adjustments.

[0069] In this embodiment, the air intake regulating device 4 includes a cigarette machine wall panel 41, a movable rod 43, a fixed rod 42, an electric push rod 45, an air intake regulating plate 46, a vibrating groove 47, and two sets of connecting rods 44. The vibrating groove 47 transports the cigarette stems output from the cigarette machine to the sampling device 1. The movable rod 43, the fixed rod 42, and the two connecting rods 44 form a four-bar linkage mechanism to connect the air intake regulating plate 46 to the cigarette machine wall panel 41. The electric push rod 45 is mounted on the cigarette machine wall panel 41 and connected to the four-bar linkage mechanism to control the opening of the air intake regulating plate 46; the air intake regulating plate 46 is mounted on the four-bar linkage mechanism to adjust the amount of cigarette stems removed.

[0070] For example, the stem removal device 3 includes a tee 31, a pneumatic butterfly valve 32, and a stem removal block 33. The tee 31 connects the outlet of the stem removal device 3 to the stem removal pipe 18 of the cigarette machine to discharge the weighed stem sticks; the pneumatic butterfly valve 32 is connected between the stem removal pipe 18 of the cigarette machine and the stem removal block 33 to realize the opening and closing of the stem removal device 3; the stem removal block 33 is installed on the frame 15 and connected to the collection box 21 to discharge the weighed stem sticks.

[0071] In this embodiment, the control component 5 includes a controller 51, a first solenoid valve 16, a second solenoid valve 34, and a digital display screen 23. The controller 51 controls the sampling device 1, the weighing device 2, and the stem removal device 3 to obtain the actual stem removal amount, and can control the operation of the air intake adjustment device 4 based on the difference between the actual stem removal amount and the process quality requirement value. The first solenoid valve 16 controls the action of the double-acting cylinder 11, the second solenoid valve 34 controls the action of the pneumatic butterfly valve 32, and the digital display screen 23 displays the weighing result of the weighing sensor 22.

[0072] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
