Description

A dual-channel modular cigarette box packaging mechanism and packaging method Technical Field

[0001] This invention belongs to the field of tobacco packaging technology, specifically relating to a dual-channel modular cigarette box packaging mechanism and packaging method. Background Technology

[0002] As a niche category pioneered by China Tobacco, medium-length cigarettes have experienced sustained market growth in recent years. This development is attributed to product and category innovation. For example, the introduction of products like Zhonghua Gold Medium-Length and Zhonghua Double Medium-Length broke the established pattern of the high-priced cigarette market, leading to a surge in medium-length cigarette sales. Major cigarette brands have launched their own medium-length products, further propelling the market's rapid growth. Therefore, creating distinctive features and selling points, and promoting product diversification from homogenization, offering consumers a wider range of choices and experiences in terms of packaging, cigarette type, flavor, and cultural characteristics, has become crucial for the future development of the medium-length cigarette market. Continuous innovation and improvement in flavor and packaging are necessary to meet consumer demands and cope with market competition. Beyond the flavor of the cigarettes themselves, consumers also have higher expectations for packaging design. However, traditional cigarette packaging machines are typically single-channel and single-flavor, failing to meet the personalized needs of consumers for multiple flavors. Modular design in packaging production allows for better flexibility and customization to meet individual and multi-flavor requirements.

[0003] This invention is proposed for this purpose. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a dual-channel modular cigarette box packaging mechanism. The method of this invention uses two colors and two flavors of cigarettes (each color corresponding to one flavor), along with two colors of inner lining paper and frame paper; the invented dual-channel modular cigarette box packaging mechanism is used for packaging these two types of cigarettes.

[0005] The technical solution of the present invention is as follows:

[0006] The first aspect of this invention discloses a dual-channel modular cigarette box packaging mechanism, wherein the cigarette box packaging uses two colors of cigarettes and is equipped with two colors of inner lining paper and frame paper; the dual-channel modular cigarette box packaging mechanism includes: a cigarette supply and arrangement system, an inner lining paper fixing, conveying and cutting system, and a frame paper fixing, conveying, cutting and folding system;

[0007] The cigarette supply and arrangement system includes: a first cigarette storage cabinet 1, a second cigarette storage cabinet 2, a first cigarette conveyor belt 3, a second cigarette conveyor belt 4, a first cigarette channel 5, a second cigarette channel 6, a baffle 7, and a guide rail 8.

[0008] The inner liner paper fixed conveying and cutting system includes: a first color inner liner paper 9, a second color inner liner paper 10, a first inner liner paper roll holder 11, a second inner liner paper roll holder 12, a first guide roller 14, a second guide roller 15, an oscillating roller 17, a speed detection device 18, a paper winding roller 16, a main drive component 19, a first cigarette conveying rail 21, and a second cigarette conveying rail 22; wherein the main drive component 19 is equipped with an active roller 13 and an inner liner paper cutter 20;

[0009] The frame paper fixed conveying, cutting and folding system includes: a two-color frame paper reel 23, a frame paper roll holder 24, a frame paper guide roller 25, a conveying pressure roller 26, a frame paper cutting and folding device 27, and a transverse conveying track 28.

[0010] The first smoke channel 5 and the second smoke channel 6 are connected to the first cigarette conveying rail 21 and the second cigarette conveying rail 22;

[0011] The first cigarette conveying rail 21 and the second cigarette conveying rail 22 are connected to the transverse conveying rail 28.

[0012] Preferably, the first cigarette storage cabinet 1, the first cigarette conveyor belt 3, and the first cigarette channel 5 are connected sequentially; the second cigarette storage cabinet 2, the second cigarette conveyor belt 4, and the second cigarette channel 6 are connected sequentially; a baffle 7 is arranged between the first cigarette channel 5 and the second cigarette channel 6; guide rails 8 are respectively arranged in the first cigarette channel 5 and the second cigarette channel 6. In the cigarette supply and arrangement system, cigarettes are initially placed in the cigarette channels for conveying in a scattered state; cigarettes of two colors are sorted and arranged in the first cigarette channel 5 and the second cigarette channel 6 respectively, and guide rails 8 are provided in both channels for cigarette arrangement, so that the cigarettes are neatly arranged in a certain direction and order. This step directly affects the neatness of the cigarette arrangement and the packaging quality. Sensors are respectively installed in the first cigarette channel 5 and the second cigarette channel 6 to detect the quantity and quality of cigarettes, ensuring that each cigarette is arranged in the correct position and direction during the cigarette sorting and arrangement process, and that there are no missing, upside-down, or damaged cigarettes. If an equipment abnormality is detected, the system will automatically stop and issue an alarm to prompt or shut down. The first smoke channel 5 and the second smoke channel 6, along with related components and the control system, are each composed and controlled by two independent modules. After the cigarette sorting, arrangement, and inspection processes are completed, the two colors of cigarettes are arranged in a double-row 5+5 pattern in the first smoke channel 5 and the second smoke channel 6, respectively, and then conveyed to the first cigarette conveying rail 21 and the second cigarette conveying rail 22 of the inner liner paper fixed conveying and cutting system for subsequent inner liner paper packaging.

[0013] Preferably, the first-colored inner liner paper 9 is mounted on the first inner liner paper roll holder 11, and the second-colored inner liner paper 10 is mounted on the second inner liner paper roll holder 12. By driving the drive roller 13 to rotate, the two types of inner liner paper are respectively wound around the first inner liner paper roll holder 11 and the second inner liner paper roll holder 12, and then pass through the first guide roller 14 and the second guide roller 15, the swing roller 17, the speed detection device 18, the winding roller 16, and the drive roller 13, before being cut into predetermined single-sheet sizes by the inner liner paper cutter 20. The cut single-sheet inner liner paper is then fed to the first cigarette conveyor rail 21 and the second cigarette conveyor rail 22. The cigarettes in the conveyor rail 22 converge from the first smoke channel 5 and the second smoke channel 6, completing the process of wrapping and forming the inner lining paper of the cigarettes. The rotation speed detection device 18, the first inner lining paper roll holder 11, the second inner lining paper roll holder 12, and the main drive component 19 are electrically connected. The rotation speed detection device 18 detects the rotation speed of the first inner lining paper roll holder 11 and the second inner lining paper roll holder 12 and feeds the speed information back to the drive roller 13. The first cigarette conveyor rail 21 and the second cigarette conveyor rail 22 are connected to the transverse conveyor rail 28 and control the conveying positions of the two types of inner lining paper respectively. The inner lining paper motor adjusts the conveying speed of the inner lining paper according to the rotation speed of the main drive component 19. The position of the oscillating roller 17 reflects the tension of the inner lining paper conveying. When the position of the oscillating roller 17 is too low, it indicates that the inner lining paper is too loose, and the paper feeding speed needs to be reduced; when the position of the oscillating roller 17 is too high, it indicates that the inner lining paper is too tight, and the paper feeding speed of the motor needs to be increased. Unlike other packaging equipment, the frame paper fixed conveying, cutting, and folding system described above is controlled by two independent modules, prohibiting the interchangeable use of the two colors of inner lining paper, although the rotation speed must be adjusted to be consistent. The inner lining paper conveying control system uses a servo motor as the drive source, and phase adjustment is performed through a PLC controller and servo driver to ensure the accuracy and stability of the inner lining paper conveying. By driving the active roller 13 to rotate, the two types of inner lining paper are unfolded and cut; the first color inner lining paper 9 and the second color inner lining paper 10 are respectively cut into preset single-sheet sizes by the inner lining paper cutter 20 through the first guide roller 14 and the second guide roller 15, the swing roller 17, the speed detection device 18, the wrapping roller 16, and the active roller 13; this process involves the conveying, unfolding, positioning, and cutting of the two types of inner lining paper. After cutting, the two colors of inner lining paper merge with the cigarettes from the first cigarette channel 5 and the second cigarette channel 6 in the first cigarette conveying rail 21 and the second cigarette conveying rail 22, respectively, to complete the cigarette inner lining paper wrapping and forming process.

[0014] Preferably, the two-color frame paper roll 23 is installed on the frame paper roll holder 24. After the two-color frame paper is unwound from the frame paper roll holder 24, it is fed into the frame paper cutting and folding device 27 through the frame paper guide roller 25 and the conveying pressure roller 26. The two-color frame paper is cut and folded into individual frame papers and then sent to the transverse conveying track 28, where it merges with the cigarette packs formed by the cigarette inner lining paper in the first cigarette conveying track 21 and the second cigarette conveying track 22, thus completing the packaging of the frame paper. The two-color frame paper roll 23 is a single-roll design. The two-color frame paper is cut into a fixed shape and length in the frame paper cutting and folding device 27, and the folding dotted lines are pressed and the edges are bent simultaneously. The two-color frame paper roll 23 is divided equally in the middle into two colors, such as the first color on the left and the second color on the right, corresponding to the inner lining paper and cigarettes of the same color, respectively, to distinguish flavors, etc. The cut single frame paper is sent to the transverse conveying track 28 to meet the cigarette packs through the frame paper guide roller 25 and the conveying pressure roller 26. During the conveying process on the transverse conveying track 28, the center distance of the two frame papers needs to be accurately positioned. This process involves adjusting the center distance of the frame papers to ensure that it is consistent with the center of the inner lining paper formed cigarette packs in the first cigarette conveying track 21 and the second cigarette conveying track 22. During the conveying process, through automation and precision control, the cigarette box packaging machine efficiently completes the conveying and combination of the two frame papers with the two inner lining papers to form cigarette packs, meeting the requirements of the continuity and stability of the high-speed production of the packaging machine.

[0015] Preferably, the inner liner paper fixing conveying and cutting system uses a servo motor as the drive source, and the phase is adjusted by a PLC controller and a servo driver.

[0016] Preferably, a formula is designed to calculate the phase adjustment of the paper feed, PLC controller, and servo drive; the formula is: Where, v: paper feed speed (unit: m / s); TPLC: scan cycle of PLC controller (unit: s); Tservo: response time of servo driver (unit: s); φ: angular velocity of servo motor (unit: radians / s).

[0017] Preferably, the formula The design steps are as follows:

[0018] (1) Calculate the distance the paper moves in one cycle of the PLC:

[0019] (2) Calculate the distance the servo drive moves in one cycle:

[0020] (3) Calculate the phase difference: The phase difference Δφ is estimated by the relative movement distance between the servo driver and the PLC controller; it is assumed that the phase difference is in degrees.

[0021] (4) Phase adjustment: In order to ensure synchronization, the phase of the servo driver needs to be adjusted; the adjusted phase φadj can be expressed as: φadj=φcurrent+Δφ, where φcurrent is the current phase;

[0022] Combining the above steps, we obtain a complete formula to calculate the required phase adjustment.

[0023] A second aspect of this invention discloses a packaging method using the aforementioned dual-channel modular cigarette box packaging mechanism, comprising the following steps:

[0024] Cigarettes of the first color in the first cigarette storage cabinet 1 are sorted and arranged on the guide rail 8 after passing through the first cigarette conveyor belt 3 into the first cigarette channel 5. Cigarettes of the second color in the second cigarette storage cabinet 2 are sorted and arranged on the guide rail 8 after passing through the second cigarette conveyor belt 4 into the second cigarette channel 6. The two colors of cigarettes are arranged in a double row of 5+5 and then conveyed to the first cigarette conveyor rail 21 and the second cigarette conveyor rail 22.

[0025] Driven roller 13 rotates, and the two colors of inner lining paper are wound around the first inner lining paper roll holder 11 and the second inner lining paper roll holder 12 respectively. Then, after passing through the first guide roller 14 and the second guide roller 15, the swing roller 17, the speed detection device 18, the winding roller 16 and the drive roller 13 respectively, they are cut into the set single sheet size by the inner lining paper cutter 20. The cut single sheet of inner lining paper is combined with the cigarettes in the first cigarette conveying rail 21 and the second cigarette conveying rail 22 to complete the cigarette inner lining paper wrapping and forming process. After the cigarette inner lining paper is wrapped and formed, it is conveyed to the transverse conveying rail 28.

[0026] Drive the conveyor roller 26 to rotate, and the two-color frame paper roll 23 installed on the frame paper roll frame 24 rotates. After the two-color frame paper is wrapped around the frame paper roll frame 24, it is fed into the frame paper cutting and folding device 27 through the frame paper guide roller 25 and the conveyor roller 26 respectively. The two-color frame paper is cut and folded into single frame papers and then sent to the transverse conveyor track 28, where it merges with the cigarette packs formed by the cigarette inner lining paper in the first cigarette conveyor track 21 and the second cigarette conveyor track 22, thus completing the packaging of the frame paper.

[0027] After the frame paper and cigarette pack are finished, they are placed into the outer packaging flat box, completing the packaging process of the cigarette box.

[0028] The beneficial effects of this invention are:

[0029] 1. The dual-channel modular cigarette box packaging mechanism of the present invention is a dual-channel packaging system. The cigarette supply and arrangement, as well as the fixing, conveying, and cutting of the inner liner paper and frame paper, are controlled by two independent modules. This allows for the packaging of two colors of cigarettes and two colors of inner liner paper and frame paper within a cigarette box. The packaging method of the dual-channel modular cigarette box packaging mechanism of the present invention is fully automated, resulting in high equipment operating efficiency and low modification costs.

[0030] 2. The dual-channel modular cigarette box packaging mechanism of this invention, designed for products with different flavors, functions, packaging patterns, or color schemes, utilizes combinations of different channels and modules to flexibly create new product configurations. Through this mechanism, a series of modules can be assembled to meet various packaging requirements, allowing cigarette products to better satisfy consumers' diverse and personalized tastes, thereby effectively improving packaging efficiency. This design does not alter the main parameters of the packaging materials and equipment; it only relies on the modular recombination for packaging production.

[0031] 3. The dual-channel modular cigarette box packaging mechanism of this invention has relatively independent characteristics. Therefore, in actual production, different modules and packaging materials can be flexibly adjusted and replaced. Simultaneously, different modules can be produced, repaired, and updated independently, exhibiting strong interchangeability. During interchange, the parameter settings of the modules must also be universal, ensuring standardized and uniform parameter settings, and that the interfaces between different modules are mutually compatible. Therefore, the application of modular dual-channel cigarette box packaging equipment will benefit manufacturers by allowing them to adjust packaging materials and cigarettes in a timely manner according to changes in consumer demand, shortening the cigarette production cycle and reducing manufacturing costs through modular equipment.

[0045] As shown in Figures 1 and 2, this invention discloses a dual-channel modular cigarette box packaging mechanism. The cigarette box packaging uses two colors of cigarettes, along with two colors of inner lining paper and frame paper. The dual-channel modular cigarette box packaging mechanism includes: a cigarette supply and arrangement system, an inner lining paper fixing, conveying and cutting system, and a frame paper fixing, conveying, cutting and folding system. Each color corresponds to a flavor.

[0046] The cigarette supply and arrangement system includes: a first cigarette storage cabinet 1, a second cigarette storage cabinet 2, a first cigarette conveyor belt 3, a second cigarette conveyor belt 4, a first cigarette channel 5, a second cigarette channel 6, a baffle 7, and a guide rail 8.

[0047] The inner liner paper fixed conveying and cutting system includes: a first color inner liner paper 9, a second color inner liner paper 10, a first inner liner paper roll holder 11, a second inner liner paper roll holder 12, a first guide roller 14, a second guide roller 15, an oscillating roller 17, a speed detection device 18, a paper winding roller 16, a main drive component 19, a first cigarette conveying rail 21, and a second cigarette conveying rail 22; wherein the main drive component 19 is equipped with an active roller 13 and an inner liner paper cutter 20;

[0048] The frame paper fixed conveying, cutting and folding system includes: a roll of two-color frame paper 23, a frame paper roll frame 24, a frame paper guide roller 25, a conveying pressure roller 26, a frame paper cutting and folding device 27, and a transverse conveying track 28.

[0049] The first smoke channel 5 and the second smoke channel 6 are connected to the first cigarette conveying rail 21 and the second cigarette conveying rail 22;

[0050] The first cigarette conveying rail 21 and the second cigarette conveying rail 22 are connected to the transverse conveying rail 28.

[0051] The system comprises a first cigarette storage cabinet 1, a first cigarette conveyor belt 3, and a first cigarette channel 5, connected sequentially; a second cigarette storage cabinet 2, a second cigarette conveyor belt 4, and a second cigarette channel 6, connected sequentially; a baffle 7 is positioned between the first and second cigarette channels 5 and 6; and guide rails 8 are installed in both channels. In this cigarette supply and arrangement system, cigarettes are initially placed randomly within the channels for transport. Two colors of cigarettes are then sorted and arranged within the first and second channels, respectively. Guide rails 8 are installed in both channels to ensure the cigarettes are arranged neatly in a specific direction and order. This step directly affects the neatness of the cigarette arrangement and the packaging quality. Sensors are installed in both channels 5 and 6 to detect the quantity and quality of the cigarettes. During the sorting and arrangement process, each cigarette is ensured to be arranged in the correct position and direction, with no missing, upside-down, or damaged cigarettes. If an abnormality is detected, the system will automatically stop and issue an alarm or shut down. The first smoke channel 5 and the second smoke channel 6, along with related components and the control system, are each composed and controlled by two independent modules. After the cigarette sorting, arrangement, and inspection processes are completed, the two colors of cigarettes are arranged in a double-row 5+5 pattern in the first smoke channel 5 and the second smoke channel 6, respectively, and then conveyed to the first cigarette conveying rail 21 and the second cigarette conveying rail 22 of the inner liner paper fixed conveying and cutting system for subsequent inner liner paper packaging.

[0052] The first-color inner liner paper 9 is mounted on the first inner liner paper roll holder 11, and the second-color inner liner paper 10 is mounted on the second inner liner paper roll holder 12. By driving the drive roller 13 to rotate, the two types of inner liner paper are respectively wound around the first inner liner paper roll holder 11 and the second inner liner paper roll holder 12, and then pass through the first guide roller 14 and the second guide roller 15, the swing roller 17, the speed detection device 18, the winding roller 16, and the drive roller 13, before being cut into predetermined single-sheet sizes by the inner liner paper cutter 20. The cut single-sheet inner liner paper is then fed to the first cigarette conveyor rail 21 and the second cigarette conveyor rail 22. The cigarettes in the conveyor rail 22 converge from the first smoke channel 5 and the second smoke channel 6, completing the process of wrapping and forming the inner lining paper of the cigarettes. The rotation speed detection device 18, the first inner lining paper roll holder 11, the second inner lining paper roll holder 12, and the main drive component 19 are electrically connected. The rotation speed detection device 18 detects the rotation speed of the first inner lining paper roll holder 11 and the second inner lining paper roll holder 12 and feeds the speed information back to the drive roller 13. The first cigarette conveyor rail 21 and the second cigarette conveyor rail 22 are connected to the transverse conveyor rail 28 and control the conveying positions of the two types of inner lining paper respectively. The inner lining paper motor adjusts the conveying speed of the inner lining paper according to the rotation speed of the main drive component 19. The position of the oscillating roller 17 reflects the tension of the inner lining paper conveying. When the position of the oscillating roller 17 is too low, it indicates that the inner lining paper is too loose, and the paper feeding speed needs to be reduced; when the position of the oscillating roller 17 is too high, it indicates that the inner lining paper is too tight, and the paper feeding speed of the motor needs to be increased. Unlike other packaging equipment, the frame paper fixed conveying, cutting, and folding system described above is controlled by two independent modules, prohibiting the interchangeable use of the two colors of inner lining paper, although the rotation speed must be adjusted to be consistent. The inner lining paper conveying control system uses a servo motor as the drive source, and phase adjustment is performed through a PLC controller and servo driver to ensure the accuracy and stability of the inner lining paper conveying. By driving the active roller 13 to rotate, the two types of inner lining paper are unfolded and cut; the first color inner lining paper 9 and the second color inner lining paper 10 are respectively cut into preset single-sheet sizes by the inner lining paper cutter 20 through the first guide roller 14 and the second guide roller 15, the swing roller 17, the speed detection device 18, the wrapping roller 16, and the active roller 13; this process involves the conveying, unfolding, positioning, and cutting of the two types of inner lining paper. After cutting, the two colors of inner lining paper merge with the cigarettes from the first cigarette channel 5 and the second cigarette channel 6 in the first cigarette conveying rail 21 and the second cigarette conveying rail 22, respectively, to complete the cigarette inner lining paper wrapping and forming process.

[0053] The two-color frame paper roll 23 is installed on the frame paper roll frame 24. After the two-color frame paper is unwound from the frame paper roll frame 24, it is fed into the frame paper cutting and folding device 27 through the frame paper guide roller 25 and the conveying pressure roller 26. The two-color frame paper is cut and folded into single frames and then sent to the transverse conveying track 28, where it merges with the cigarette packs formed by the cigarette inner lining paper in the first cigarette conveying track 21 and the second cigarette conveying track 22, thus completing the packaging of the frame paper. The two-color frame paper roll 23 is a single-roll design. The two-color frame paper is cut into a fixed shape and length in the frame paper cutting and folding device 27, and the folding dotted lines are pressed and the edges are bent simultaneously. The two-color frame paper roll 23 is divided equally in the middle into two colors, such as the first color on the left and the second color on the right, corresponding to the inner lining paper and cigarettes of the same color, respectively, to distinguish flavors, etc. The cut single frame paper is sent to the transverse conveying track 28 to meet the cigarette packs through the frame paper guide roller 25 and the conveying pressure roller 26. During the conveying process on the transverse conveying track 28, the center distance of the two frame papers needs to be accurately positioned. This process involves adjusting the center distance of the frame papers to ensure that it is consistent with the center of the inner lining paper formed cigarette packs in the first cigarette conveying track 21 and the second cigarette conveying track 22. During the conveying process, through automation and precision control, the cigarette box packaging machine efficiently completes the conveying and combination of the two frame papers with the two inner lining papers to form cigarette packs, meeting the requirements of the continuity and stability of the high-speed production of the packaging machine.

[0054] The inner liner paper fixing, conveying and cutting system uses a servo motor as the drive source and performs phase adjustment through a PLC controller and a servo driver.

[0055] The inner liner paper fixing, conveying and cutting system uses a servo motor as the drive source and performs phase adjustment through a PLC controller and a servo driver.

[0056] Preferably, a formula is designed to calculate the phase adjustment of the paper feed, PLC controller, and servo drive; the formula is: Where, v: paper feed speed (unit: m / s); TPLC: scan cycle of PLC controller (unit: s); Tservo: response time of servo driver (unit: s); φ: angular velocity of servo motor (unit: radians / s).

[0057] Among them, formula The design steps are as follows:

[0058] (1) Calculate the distance the paper moves in one cycle of the PLC:

[0059] (2) Calculate the distance the servo drive moves in one cycle:

[0060] (3) Calculate the phase difference: The phase difference Δφ is estimated by the relative movement distance between the servo driver and the PLC controller; it is assumed that the phase difference is in degrees.

[0061] (4) Phase adjustment: In order to ensure synchronization, the phase of the servo driver needs to be adjusted; the adjusted phase φadj can be expressed as: φadj=φcurrent+Δφ, where φcurrent is the current phase;

[0062] Combining the above steps yields a complete formula for calculating the required phase adjustment. This formula provides a method to estimate how many degrees of phase adjustment the servo drive needs to perform to ensure synchronization with paper feed, given a PLC controller cycle and servo drive response time. In practical applications, adjustments need to be made based on specific equipment performance and operating environment. Furthermore, factors such as paper acceleration, deceleration, and load variations must be considered.

[0063] The packaging method for cigarette boxes using the aforementioned dual-channel modular cigarette box packaging mechanism includes the following steps:

[0064] Cigarettes of the first color in the first cigarette storage cabinet 1 are sorted and arranged on the guide rail 8 after passing through the first cigarette conveyor belt 3 into the first cigarette channel 5. Cigarettes of the second color in the second cigarette storage cabinet 2 are sorted and arranged on the guide rail 8 after passing through the second cigarette conveyor belt 4 into the second cigarette channel 6. The two colors of cigarettes are arranged in a double row of 5+5 and then conveyed to the first cigarette conveyor rail 21 and the second cigarette conveyor rail 22.

[0065] Driven roller 13 rotates, and the two colors of inner lining paper are wound around the first inner lining paper roll holder 11 and the second inner lining paper roll holder 12 respectively. Then, after passing through the first guide roller 14 and the second guide roller 15, the swing roller 17, the speed detection device 18, the winding roller 16 and the drive roller 13 respectively, they are cut into the set single sheet size by the inner lining paper cutter 20. The cut single sheet of inner lining paper is combined with the cigarettes in the first cigarette conveying rail 21 and the second cigarette conveying rail 22 to complete the cigarette inner lining paper wrapping and forming process. After the cigarette inner lining paper is wrapped and formed, it is conveyed to the transverse conveying rail 28.
