Description

Technical Field

[0001] At least one embodiment of the present invention relates to the technical field of cigarette making equipment, and in particular to a conveying device for pre-cut self-adhesive tipping paper for cigarettes. Background Art

[0002] Cigarette tipping paper, a key material connecting cigarettes to filters, plays a crucial role in the cigarette production process. Conventional technology typically utilizes an online gluing and splicing process, whereby the tipping paper is coated with glue before contact with the cigarette and filter. This glue-coated tipping paper securely bonds the cigarette and filter together.

[0003] However, during the gluing process, too little glue can lead to loose connections and compromise the structural integrity of the product; while too much glue can cause overflow and sticking, impacting the appearance of the finished cigarette and the consumer experience. Furthermore, performance parameters such as the glue's drying speed and viscosity must be precisely controlled to meet the speed requirements of different production lines. These factors collectively restrict both production speed increases and product quality stability, creating pressing technical challenges in cigarette production. Summary of the Invention

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0033] The terms used herein are only for describing specific embodiments and are not intended to limit the present invention. The terms "comprise", "include", etc. used herein indicate the presence of the features, steps, operations and / or components, but do not exclude the presence or addition of one or more other features, steps, operations or components.

[0034] All terms used herein, including technical and scientific terms, have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0035] When expressions such as “at least one of A, B, and C, etc.” are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art. For example, “a system having at least one of A, B, and C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc. When expressions such as “at least one of A, B, or C, etc.” are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art. For example, “a system having at least one of A, B, or C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc.

[0036] It should also be noted that directional terms such as "upper," "lower," "front," "back," "left," and "right" mentioned in the embodiments are merely references to the directions in the accompanying drawings and are not intended to limit the scope of protection of the present invention. Throughout the drawings, identical elements are represented by identical or similar reference numerals. Conventional structures or configurations will be omitted where they may cause confusion in understanding the present invention.

[0037] During the development of this invention, it was discovered that window-type tipping paper, which features holes of varying sizes and patterns, not only meets the functional requirements of cigarettes but also enhances their aesthetics and recognition. However, practical applications of window-type tipping paper also present a number of technical challenges.

[0038] During the splicing process, window-type tipping paper requires gluing using a glue roller. However, due to the holes on the surface of the tipping paper, after a period of operation, a small amount of glue may overflow through these holes and adhere to the paper cutting wheel and the splicing wheel, resulting in glue overflow. This glue overflow problem not only leads to a decrease in production stability, but can also cause frequent downtime. In addition, window-type tipping paper generally adopts a glue-free design in the window area. This means that the patterns and lines on the window are not covered with glue, and the lack of glue fixing effect leads to frequent warping in the window area, affecting the splicing quality, damaging the aesthetic appearance of the finished cigarettes, and reducing the market competitiveness of the product.

[0039] Figure 1 Shown is a side view of a delivery device according to an embodiment of the present invention.

[0040] As one aspect of an embodiment of the present invention, a conveying device for pre-cut self-adhesive tipping paper for cigarettes is provided, such as Figure 1As shown, the conveying device includes a conveying mechanism 1 and a separating mechanism 4. The conveying mechanism 1 is used to convey self-adhesive tipping paper 8, which includes multiple tipping papers 81 and a base paper 82. Each tipping paper 81 includes an adhesive surface with self-adhesive and an adhesive-free surface facing away from the adhesive surface. The multiple tipping papers 81 are sequentially adhered to the base paper 82. The separating mechanism 4 is disposed downstream of the conveying mechanism 1 along the conveying direction of the self-adhesive tipping paper 8. The self-adhesive tipping paper 8 translates along a first direction between the conveying mechanism 1 and the separating mechanism 4, guided by the separating mechanism 4. The separating mechanism 4 deflects the base paper 82 along a second direction forming an angle with the first direction. The rigidity of the tipping paper 81 overcomes the adhesive force between the tipping paper 81 and the base paper 82, causing the tipping paper 81 to separate from the base paper 82.

[0041] According to the conveying device for pre-cut self-adhesive tipping paper for cigarettes according to the embodiment of the present invention, by using pre-cut self-adhesive tipping paper 8 with pre-coated self-adhesive, the tipping paper is glued to the back and pre-cut according to the preset size before being conveyed, thereby avoiding the phenomenon of inaccurate glue control during the online gluing process, resulting in loose tipping or excessive glue causing glue overflow, adhesion, etc. In addition, since there is no need for online gluing and waiting for glue to dry, the operating speed of the cigarette production line can be increased, and the process steps of gluing and paper cutting can be reduced, reducing the use and maintenance costs of glue coating equipment and paper cutting equipment. The conveying device realizes the efficient separation of tipping paper 81 and base paper 82 through the coordinated work of the conveying mechanism 1 and the separation mechanism 4, making the entire tipping process more concise, and at the same time, it can also reduce the scrap rate caused by improper use of glue.

[0042] Figure 2 A perspective view of a cigarette is shown.

[0043] like Figure 2 As shown, the cigarette 9 includes a cigarette stick 92, a filter tip 91 and a tipping paper 81. The tipping paper 81 connects the cigarette stick 92 and the filter tip 91.

[0044] Tipping paper 81, also known as tipping paper, is a special paper used to connect the cigarette 92 and filter 91 during cigarette production. This specially treated paper typically has a certain degree of air permeability and tensile strength, firmly bonding the filter 91 and cigarette 92 together to form a complete cigarette 9.

[0045] According to an embodiment of the present invention, the filter tip 91 can be made of materials such as acetate fiber and processed into a filter rod through a special process to filter harmful substances in the smoke. The cigarette 92 is made of tobacco and cigarette paper and is the main part of the cigarette 9.

[0046] According to an embodiment of the present invention, the pre-cut self-adhesive tipping paper 8 can be a window-type tipping paper, i.e., the tipping paper 81 is provided with holes of varying sizes and patterns, creating a window effect. The self-adhesive adhesive is applied to one side of the tipping paper 81, forming an adhesive surface. During the cigarette splicing process, this adhesive surface adheres to the filter 91 and the cigarette stick 92, forming the cigarette 9 with the filter 91. The adhesive surface is exposed to the cigarette 9, forming part of the outer surface of the cigarette 9. It should be understood that the embodiments of the present invention are not limited to this embodiment, and the tipping paper 81 can also be ordinary tipping paper without a window effect.

[0047] There may be a certain gap between two adjacent pieces of tipping paper 81 , so as to avoid adhesion between the two adjacent pieces of tipping paper 81 and improve the efficiency of cigarette 9 .

[0048] According to the conveying device for pre-cut self-adhesive tipping paper for cigarettes according to the embodiment of the present invention, the pre-cut self-adhesive tipping paper 8 is formed by pre-coating the tipping paper 81 with self-adhesive in a professional environment in the cigarette 9. In the case that the tipping paper 81 is a window-type tipping paper 81, the self-adhesive can be coated on the entire adhesive surface of the tipping paper 81, thereby avoiding the problem of tipping paper 81 warping caused by the no-glue design in the window area during the online gluing process, and also avoiding the phenomenon of glue overflowing from the nozzle through the window hole when the glue roller is gluing, causing glue to adhere to the paper cutting wheel 31 and the rubbing wheel 72, thereby improving production stability, reducing the frequency of equipment shutdown and product rejection, and ensuring the aesthetics and quality consistency of the finished cigarette 9.

[0049] By using pre-cut self-adhesive tipping paper 8, the gluing equipment on the traditional production line is eliminated, reducing the emission of volatile organic compounds (VOCs) in the cigarette production workshop 9, improving the working environment, and reducing health hazards to operators. Furthermore, the pre-coated self-adhesive tipping paper 8 has a uniform and controllable adhesive layer thickness, avoiding the excessive use of glue in the traditional gluing process, reducing glue waste, improving resource utilization, eliminating the gluing step, reducing the failure rate of the conveyor device, and reducing maintenance resource consumption.

[0050] According to an embodiment of the present invention, Figure 1 As shown, the included angle is an obtuse angle.

[0051] When the separation mechanism 4 deflects the backing paper 82 in a second direction that forms an obtuse angle with the first direction, the deflection of the backing paper 82 is smoother, reducing stress concentration during the separation of the tipping paper 81 from the backing paper 82 and effectively preventing potential tearing or deformation of the tipping paper 81 during the separation process. Furthermore, the obtuse-angle deflection provides more time for the tipping paper 81 to bend, allowing its rigidity to more evenly overcome the adhesive force between it and the backing paper 82, achieving a more stable and reliable separation effect.

[0052] Figure 3A side view of a separation mechanism according to an embodiment of the present invention is shown.

[0053] According to an embodiment of the present invention, Figure 1 and Figure 3 As shown, the separation mechanism 4 includes a peeling plate 41, which has a first surface and a second surface arranged in sequence along the conveying direction of the base paper 82. The first surface is parallel to the first direction, and the second surface is parallel to the second direction. The first surface and the second surface intersect to form a separation end of the peeling plate 41. The self-adhesive tipping paper 8 is input from the front end of the peeling plate 41 along the first surface. The base paper 82 is separated from the tipping paper 81 at the separation end and moves horizontally along the second surface.

[0054] The first surface is parallel to the first direction, which can ensure that the self-adhesive tipping paper 8 can be stably conveyed when entering the peeling plate 41, avoiding premature separation or deviation of the tipping paper 81 and the base paper 82, and providing a good basic condition for the subsequent separation process.

[0055] The second surface is parallel to the second direction, so that the bottom paper 82 can move smoothly along the predetermined path after separation, thereby ensuring the continuity and consistency of the separation process.

[0056] The separation end formed by the intersection of the first and second surfaces becomes a precise separation point. At the separation end, the rigidity of the tipping paper 81 cooperates with the force generated by the deflection of the bottom paper 82, allowing the bottom paper 82 to separate from the tipping paper 81. This improves the reliability and stability of the separation and reduces material waste caused by improper separation.

[0057] As an example, the first surface and the second surface may intersect through an arc surface, so that the bottom paper 82 can move smoothly from the first surface to the second surface.

[0058] The peeling plate 41 further has a third surface opposite to the first surface, and the second surface is connected between the first surface and the third surface.

[0059] The third surface may be parallel to the first surface, or a plane on which the third surface is located may intersect with a plane on which the first surface is located.

[0060] According to an embodiment of the present invention, Figure 3 As shown, the separation mechanism 4 further includes a paper pressing roller 42 , which is arranged at the front end of the peeling plate 41 parallel to the first surface and is suitable for laminating the self-adhesive tipping paper 8 to the first surface.

[0061] The platen roller 42 is disposed on the first surface of the peeling plate 41 .

[0062] The pressure roller 42 is positioned parallel to the first surface at the front end of the peeling plate 41. It applies appropriate pressure to the self-adhesive tipping paper 8, ensuring a tight fit between it and the first surface. This eliminates any air gaps between the first surface and the tipping paper 8, as well as any wrinkles that may form on the tipping paper 8. This creates ideal physical conditions for the separation of the tipping paper 81 and the backing paper 82 at the separation end. This tight fit ensures that the tipping paper 8 has uniform tension distribution and stable stiffness upon reaching the separation end, enabling a clean and efficient separation of the backing paper 82 along the predetermined second direction. Furthermore, by eliminating air gaps and wrinkles, the adhesive force between the tipping paper 81 and the backing paper 82 is more evenly distributed, avoiding problems such as incomplete separation or tearing of the tipping paper 81 due to localized stress concentration, thereby improving the reliability and consistency of the separation process.

[0063] According to an embodiment of the present invention, Figure 1 and Figure 3 As shown, the pressing roller 42 includes a mounting base 421 and a plurality of balls 422. The plurality of balls 422 are respectively mounted on the mounting base 421. When the self-adhesive tipping paper 8 moves along the first surface, the plurality of balls 422 roll in contact with the self-adhesive tipping paper 8, applying a force toward the first surface to prevent the tipping paper 81 from bulging or denting on the first surface.

[0064] The plurality of balls 422 are arranged at intervals along the width direction of the self-adhesive tipping paper 8. Alternatively, the plurality of balls 422 can be arranged in an array.

[0065] The number of the balls 422 can be any number among 3, 4, 5 and 10. It should be understood that the embodiments of the present invention are not limited thereto, and the number of the balls 422 can be set according to actual needs.

[0066] The combination of mounting base 421 and multiple ball bearings 422, through which the multiple ball bearings 422 roll in contact with the self-adhesive tipping paper 8, reduces frictional resistance during transport, minimizing damage to the paper surface or the possibility of damage to the surface coating. Furthermore, the multiple ball bearings 422 apply evenly distributed pressure to the self-adhesive tipping paper 8, ensuring that the tipping paper 81 adheres tightly to the first surface across its entire width, preventing localized bulging or denting.

[0067] According to an embodiment of the present invention, Figure 1 As shown, the conveying device further includes an adsorption mechanism 3 , which is suitable for adsorbing the tipping paper 81 .

[0068] The suction mechanism 3 includes a cutting wheel 31 and a negative pressure assembly (not shown). The cutting wheel 31 is configured to rotate about a first axis and has a plurality of suction holes formed along its circumference. The negative pressure assembly is adapted to apply negative pressure to the suction holes, causing them to adhere to the adhesive surface.

[0069] The multiple adsorption holes on the cutting wheel 31 adsorb the adhesive surface under negative pressure. The adsorption force provided by the cutting wheel 31 is greater than the tension of the tipping paper 81, so that the tipping paper 81 moves along with the cutting wheel 31.

[0070] When the rotation speed of the adsorption mechanism 3 remains unchanged, the rotation speed of the winding device is configured to gradually decrease as the thickness of the base paper 82 being wound on the winding mechanism 2 increases, so as to keep the linear speed of the base paper 82 matched with the linear speed of the tipping paper 81, thereby avoiding changes in the tension between the base paper 82 and the tipping paper 81 and preventing the base paper 82 and the tipping paper 81 from being overstretched or loosened due to speed inconsistency.

[0071] According to an embodiment of the present invention, Figure 1 As shown, the conveying mechanism 1 includes a paper tray 11 and a plurality of conveyor rollers 12. The paper tray 11 is adapted to support the self-adhesive tipping paper 8. The plurality of conveyor rollers 12 are spaced apart between the paper tray 11 and the separation mechanism 4 along the conveying direction of the self-adhesive tipping paper 8 and are adapted to convey the self-adhesive tipping paper 8 from the paper tray 11 to the separation mechanism 4 along the conveying direction.

[0072] The paper tray rack 11 is used to support the pre-cut self-adhesive tipping paper roll; the conveying roller 12 is used to pull the pre-cut self-adhesive tipping paper 8 out of the paper tray rack 11.

[0073] The paper reel 11 serves as a support for the self-adhesive tipping paper 8, ensuring the stability of the paper roll during transport, preventing it from shaking or shifting, and providing a good starting point for subsequent transport. Multiple conveyor rollers 12 are spaced along the transport direction, forming a continuous transport path. This ensures smooth and continuous transport of the self-adhesive tipping paper 8 from the paper reel 11 to the separation mechanism 4, avoiding the uneven tension and paper breakage that can occur with single-point transport.

[0074] The conveying roller 12 may include a paper feed wheel and a rubber pressure roller. The paper feed wheel may be connected to a servo motor, and the paper feed wheel and the rubber pressure roller roll together and pull the pre-cut self-adhesive tipping paper 8 together to ensure that the self-adhesive tipping paper 8 can smoothly enter the subsequent processing link.

[0075] According to an embodiment of the present invention, Figure 1 As shown, the above-mentioned conveying device further includes a tensioning mechanism 6, which is arranged between the winding mechanism 2 and the separation mechanism 4, and is suitable for tensioning the bottom paper 82 during the winding process of the bottom paper 82.

[0076] The tensioning mechanism 6 can adjust the tension of the bottom paper 82 in real time during the winding process, ensuring that the bottom paper 82 always maintains an appropriate tension state, and avoiding uneven winding or looseness caused by tension fluctuations.

[0077] According to an embodiment of the present invention, Figure 1 As shown, the tensioning mechanism 6 includes a tensioning shaft 61, a tensioning arm 62, and a tensioning pulley 63. The axis of the tensioning shaft 61 is parallel to the first axis. One end of the tensioning arm 62 is connected to the tensioning shaft 61, and the tensioning pulley 63 is disposed at the other end of the tensioning arm 62. The tensioning pulley 63 is configured to rotate about a tensioning axis parallel to the first axis. Driven by the tensioning arm 62, the tensioning pulley 63 rotates about the tensioning shaft 61 to tension or loosen the bottom paper 82.

[0078] The tensioning arm 62 rotates around the tensioning shaft 61 , so that the tensioning wheel 63 can swing within a certain range and can be adjusted in real time according to the actual tension requirement of the bottom paper 82 .

[0079] According to an embodiment of the present invention, the tensioning mechanism 6 further includes two conveying rollers 64. Along the conveying direction of the bottom paper 82, the tensioning wheel 63 is disposed between the two conveying rollers 64 to provide support force for tensioning the bottom paper 82 through the conveying rollers 64.

[0080] As shown in FIG1 , when tension needs to be increased, the tensioning arm 62 drives the tensioning wheel 63 to swing counterclockwise, increasing the tension on the bottom paper 82. When tension needs to be reduced, the tensioning arm 62 swings clockwise, appropriately loosening the bottom paper 82, thereby achieving flexible tension adjustment. It should be understood that the embodiments of the present invention are not limited to this.

[0081] According to an embodiment of the present invention, Figure 1 As shown, the above-mentioned conveying device also includes a cigarette 9 mechanism 7, which is suitable for clamping the filter 91 and the cigarette 92 and rotating them around a second axis parallel to the first axis, and making the filter 91 and the cigarette 92 contact the adhesive surface of the tipping paper 81, so as to adhere the tipping paper 81 to the filter 91 and the cigarette 92, so that the filter 91 and the cigarette 92 are connected to form a cigarette 9 with a filter 91.

[0082] According to an embodiment of the present invention, Figure 1 As shown, the cigarette rolling mechanism 7 includes an integrated wheel 71 and a cigarette-rolling wheel. The integrated wheel 71 is adapted to clamp the filter 91 and cigarette 92 and is configured to rotate in a direction opposite to that of the paper-cutting wheel 31, thereby adhering the tipping paper 81 to the filter 91 and cigarette 92. The cigarette-rolling wheel is arranged parallel to the integrated wheel 71 and is configured to rotate in a direction opposite to that of the integrated wheel 71, thereby rotating the cigarette 92 and filter 91 and adhering the tipping paper 81 to the cigarette 92 and filter 91.

[0083] The cigarette 9 mechanism 7 can clamp the filter 91 and the cigarette 92 and rotate around the second axis to ensure that the connecting end surface of the filter 91 and the cigarette 92 is in accurate contact with the adhesive surface of the tipping paper 81, so that the adhesive surface of the tipping paper 81 adheres to the filter 91 and the cigarette 92. The adhesive force of the tipping paper 81 on the filter 91 and the cigarette 92 overcomes the adsorption force of the paper cutting wheel 31, so that the tipping paper 81 is separated from the paper cutting wheel 31, so that the tipping paper 81 rotates with the integrated wheel 71 and is rubbed and connected by the cigarette rubbing wheel, so that the tipping paper 81 adheres to the filter 91 and the outer periphery of the cigarette 92. Then, through subsequent processes, the middle part of the filter 91 can be cut radially to complete the preparation of the finished cigarette 9.

[0084] When the tipping paper 81 cut into sheets rotates to a certain position along with the paper cutting wheel 31, the sheet tipping paper 81 sticks to the filter 91 and the cigarette 92 on the integrating wheel 71, and the filter 91 and the cigarette 92 adhered with the tipping paper 81 are transferred to the cigarette rolling wheel through the integrating wheel 71 for rolling and splicing, thereby completing the entire cigarette 9 production process.

[0085] The above-mentioned conveying device further includes a controller (not shown in the figure), which is used to coordinate the speed matching of the paper feeding wheel, the winding device, and the paper cutting wheel 31.

[0086] Figure 4 1 shows a perspective view of a winding mechanism 2 according to an embodiment of the present invention, Figure 5 FIG. 1 shows a side view of a winding mechanism 2 according to an embodiment of the present invention.

[0087] like Figure 4 and Figure 5 As shown, the winding mechanism 2 includes a winding motor 21 and a winding roller connected to the winding motor 21 in a transmission manner.

[0088] The winding roller includes a positioning plate 24, a roller shaft 22, and an elastic member 23. The roller shaft 22 extends from the side of the positioning plate 24 facing away from the winding motor 21. The radial ends of the roller shaft 22 are radially inwardly recessed to form grooves, extending parallel to the axial direction of the roller shaft 22. The elastic member 23 can be U-shaped.

[0089] Furthermore, the elastic member 23 may include a connecting arm 231 and two elastic arms ( Figure 4 and Figure 5 , the elastic arm is located in the groove).

[0090] The two elastic arms each have a fixed end connected to the connecting arm 231 and a free end facing away from the fixed end. When the two elastic arms are not subject to external forces, the distance between the two free ends is smaller than the distance between the two fixed ends, and smaller than the distance between the bottoms of the two grooves. The distance between the two fixed ends can be slightly larger than the distance between the bottoms of the two grooves to facilitate insertion of the elastic arms into the grooves.

[0091] The two elastic arms can be inserted into the groove from the insertion end facing away from the positioning plate 24. Furthermore, by holding the connecting arm 231, the free end of the elastic arm is inserted from the insertion end of the groove, and the elastic member 23 is pushed to translate along the axial direction of the roller shaft 22, and the two elastic arms are respectively inserted into the two grooves.

[0092] A gripping portion may also be provided on the side of the connecting arm 231 facing away from the elastic arm. The gripping portion may be a bump or a handle.

[0093] When the end of the bottom paper 82 is inserted into the opening of the U-shaped card, the two elastic arms of the U-shaped card will move closer to each other due to the elasticity, clamping the bottom paper 82 between at least one groove and the elastic arm. The first circle of the bottom paper 82 wound on the roller 22 can be fixed on the roller 22, and the bottom paper 82 can be reeled by rotating the roller 22. When the bottom paper 82 is reeled to the full reel position of the positioning plate 24, the reeling mechanism 2 stops operating, and the reel of bottom paper 82 can be removed by pulling the elastic member 23 out of the groove.

[0094] Alternatively, the roller 22 may have multiple grooves spaced apart along the circumference. The elastic member 23 may have multiple elastic arms corresponding one-to-one to the multiple grooves, and the multiple elastic arms may be inserted from the insertion ends of the multiple grooves. In this way, the multiple elastic members 23 and the multiple grooves can simultaneously fix the bottom paper 82, distributing the force at the fixing point. This ensures that even under high-speed rewinding or high tension on the bottom paper 82, the end of the bottom paper 82 can be firmly fixed and prevented from loosening or slipping. For example, the number of grooves and elastic arms can also be three or four.
