Description

Technical Field

[0001] This invention belongs to the field of tobacco packaging technology, and in particular relates to a flat-rotating flip-top carton filling system. Background Technology

[0002] Tobacco packaging plays a crucial role in tobacco sales. Through innovation in design and material selection, tobacco manufacturers can offer distinctive packaging products. Innovative packaging designs can attract consumers' attention, increasing product appeal and competitiveness. Simultaneously, tobacco packaging provides tobacco manufacturers with opportunities for improvement and innovation to adapt to changing market demands and meet the personalized needs of different consumer groups. A well-designed packaging structure and function ensure the preservation and freshness of tobacco products while providing ease of opening, portability, and storage. By optimizing the user experience, tobacco manufacturers can build consumer loyalty and improve customer satisfaction. Tobacco packaging equipment is essential for the production efficiency of tobacco manufacturers. Efficient packaging equipment can increase the speed and efficiency of production lines, reducing manual labor and resource waste. Automated and intelligent packaging equipment enables fast and accurate packaging processes, ensuring consistent and stable product quality. By improving production efficiency, tobacco manufacturers can reduce production costs, increase production capacity, and meet changing market demands.

[0003] Hard-sided flip-top cartons are currently a popular tobacco packaging choice among consumers. As the outer packaging of tobacco products, they directly determine the appearance and perceived quality of the product. This type of tobacco packaging consists of a box body and a flip-top lid, while the box body houses two layers of cigarette packs arranged in a straight line. However, the manufacturing process of hard-sided flip-top cartons is relatively complex. In tobacco manufacturing enterprises, the packaging process cannot be directly formed and completed on the tobacco production line. Therefore, before use, this type of carton is a closed, complete box body, typically containing materials such as a film, ribbons, and desiccants to cover the cigarette packs.

[0004] Because rigid flip-top cartons are a relatively new packaging format, there is currently a lack of dedicated automated filling and packaging equipment suitable for them. Therefore, in most cases, manual filling by operators is required. However, this manual filling method has several problems, such as low efficiency, high cost, and difficulty in ensuring quality control.

[0005] One of the main problems with manual filling is its low efficiency. Compared to automated equipment, manual filling requires human operation, which is slower and prone to fatigue. This limits production line capacity and efficiency, increasing production time and labor costs. Furthermore, manual filling presents quality control challenges. Human operation is prone to errors or inconsistencies, leading to increased errors and quality problems during the filling process. This poses a challenge to product consistency and quality stability, potentially affecting consumer satisfaction and trust. Additionally, manual filling increases production costs. Hiring and training operators requires additional human resources and expenses. Moreover, due to waste and losses during the filling process, material utilization efficiency cannot be maximized.

[0006] Currently, although technical solutions for automated filling production lines suitable for flip-top cigarette cartons have been publicly disclosed, there are still some shortcomings in production lines for conveyor belt-filled cigarette cartons. The main problems with this type of production line are as follows: Stability issues: Conveyor belt-filled cigarette cartons often face stability issues during the filling process. The cartons may move unstably on the conveyor belt, leading to inaccurate filling, or even jamming or blockage. This can cause production line downtime, reduced production efficiency, and even damage to equipment or products. Low efficiency: Due to stability issues and instability during the filling process, conveyor belt-filled production lines often fail to achieve the expected high efficiency. More manual intervention and monitoring may be required during the filling process to ensure accurate filling of the cigarette cartons, thus reducing the overall efficiency of the production line. Large space occupation: Conveyor belt-filled cigarette carton production lines often require a large space to accommodate the conveyor belt, filling equipment, and related auxiliary equipment. This can result in a less compact production line layout, occupying valuable production plant space.

[0007] Poor work quality: Due to instability issues during the filling process, cigarette packs may be filled incorrectly, leading to inconsistent product quality. Unstable filling can affect the appearance and structure of the cigarette packs, thereby impacting consumer perception and satisfaction.

[0008] Therefore, in order to improve the production efficiency of rigid flip-top cartons, reduce costs, and ensure quality control, tobacco manufacturers urgently need specialized automated filling and packaging equipment. Summary of the Invention

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0046] To address the problems of low efficiency, high cost, and quality control difficulties in the current production of rigid flip-top cartons, this invention provides a flat-rotating flip-top carton filling system. This system has advantages such as compact structure, improved operating efficiency, stable carton movement, and enhanced packaging quality. To further illustrate the structure of this invention, a detailed description is provided below in conjunction with the accompanying drawings:

[0047] Please see Figure 1 and Figure 2 A flat-rotating flip-top carton filling system includes a flat-rotating station conversion mechanism 1, a carton feeding mechanism 2, a carton filling mechanism 3, and a carton discharging mechanism 4. The carton feeding mechanism, the carton filling mechanism, and the carton discharging mechanism are arranged sequentially in a circumferential direction on the side of the flat-rotating station conversion mechanism.

[0048] The rotary station conversion mechanism, located at the center of this system, is the core working mechanism. Its main functions include clamping the flip-top carton and switching its position between various functional stations. It clamps the flip-top carton upside down and rotates it intermittently around a planar circumference to achieve automated processing at different circumferential stations. In this embodiment, the rotary station conversion mechanism has four circumferentially distributed stations: a feeding station, a desiccant discharge station, a filling station, and a discharging station. The feeding station is where the flip-top carton, as packaging material, enters the rotary station conversion mechanism. The desiccant discharge station is where the desiccant is discharged from the upside-down flip-top carton. The filling station is where the cigarette pack is placed into the upside-down flip-top carton. The discharging station is where the filled and closed flip-top carton is moved out of the rotary station conversion mechanism. The circumferential angle between these four stations is 90°.

[0049] The carton feeding mechanism is an automated action mechanism that pushes the flip-top carton into the feeding station of the rotary station conversion mechanism. The carton feeding mechanism is located to the side of the rotary station conversion mechanism. The carton filling mechanism is an automated action mechanism that pushes rows of cartons into the filling station of the rotary station conversion mechanism, inverting the cartons. The carton filling mechanism is located to the side of the rotary station conversion mechanism; that is, the carton feeding mechanism and the carton filling mechanism are located on opposite sides of the rotary station conversion mechanism. The carton discharging mechanism is an automated action mechanism that pushes the filled and closed flip-top carton outward from the discharging station of the rotary station conversion mechanism. The desiccant discharge station does not have a separate automated action mechanism; it relies on the structural unit of the rotary station conversion mechanism itself. The desiccant discharge station and the carton discharging mechanism are located on opposite sides of the rotary station conversion mechanism.

[0050] Please see Figure 3 and Figure 4 The horizontal rotation station conversion mechanism includes a vertical rotating shaft assembly, a horizontal rotating table 1-1, a clamping component, and a cover-opening robot assembly. The above structure consists of the main functional components of the horizontal rotation station conversion mechanism, wherein the vertical rotating shaft assembly is mounted on the frame as the active component.

[0051] A vertical shaft assembly is a component assembly capable of rotating around a vertical axis. It is a mechanical device with a vertically positioned shaft as its main body, achieving rotation through a drive system, thus forming an automated mechanism with rotary loading capabilities. The core of the vertical shaft assembly is the vertically positioned main shaft, which is the main support and rotating element of the device. The design and manufacture of the main shaft must consider factors such as load-bearing capacity, rotational smoothness, and durability. Furthermore, the drive system is also a key component, achieving the rotation of the main shaft through motors, gear transmissions, hydraulic systems, etc. Overall, the composition of this device needs to ensure structural robustness, stable operation, and ease of maintenance. The vertically positioned main shaft is the active component of the device, responsible for supporting and transmitting rotational kinetic energy. The design of the main shaft must consider factors such as load-bearing capacity, rotational speed, and axial stability. The main shaft typically needs to possess high strength and high precision to ensure that the device does not generate excessive vibration and frictional losses during rotation. The drive system is the core of the vertical shaft assembly, providing the power to achieve the rotation of the main shaft. The drive system can employ different methods such as electric motor, hydraulic drive, and pneumatic drive, with the specific choice depending on the matching and performance requirements of the tobacco packaging line. The drive system needs to have precise control capabilities to achieve accurate rotation and stopping of the device.

[0052] Specifically, the vertical rotating shaft assembly includes a main shaft 1-2 with its axis vertically aligned and a shaft driver 1-3 connected to and driving the main shaft to rotate. The main shaft is a cylindrical shaft, which, in addition to being a rotating component, also serves as the mounting component for the turntable in this system. The upper and lower ends of the main shaft are mounted on the frame via bearings, enabling it to rotate around its own axis. The shaft driver is a driving component or assembly that drives the main shaft to rotate around its own axis. In this embodiment, the shaft driver is a combination of a shaft drive motor and a cam divider assembly. That is, the shaft driver uses a servo motor, whose output shaft is connected to the input shaft of the cam divider. The cam divider is mounted on the upper end of the main shaft, and its output shaft is directly connected to the main shaft. The connection, driving structure, and working relationship of the servo motor, cam divider, and rotating shaft assembly are conventional technologies in the mechanical field.

[0053] The rotary table is a component that rotates with the spindle and has a rotation plane. The rotary table is mounted on the spindle. The lower end face of the rotary table is the rotation plane, and this end face has at least three mounting stations evenly arranged circumferentially around the spindle's axis. In this embodiment, the rotary table has a central rotating part fixed to the spindle by a flange and four outwardly protruding platform parts. The platform parts are evenly distributed circumferentially, and mounting stations are respectively provided on the lower end face of the platform parts. Each mounting station can be used for mounting the flip-top box.

[0054] Please see Figure 5 The clamping components 1-4 are located at the clamping station of the turntable. These components are used to position and fix the inverted flip-top box at the clamping station. Specifically, the clamping components form a clamping groove with an outer opening, and the inner wall of the clamping groove has a protrusion 1-41 for inserting into the side seam of the box. The closed flip-top box, as the basic packaging material of this system, has a circumferential groove between its lid and body. This clamping component uses this groove to clamp the flip-top box inverted. The flip-top box is pushed horizontally into the clamping groove, that is, horizontally pushed in from the outer opening of the clamping groove. During this pushing process, the protrusion slides from the groove end of the flip-top box into the groove, thus achieving clamping. In this embodiment, the mounting component includes two mounting blocks symmetrically arranged on the left and right sides, and limiting blocks 1-5 located on the inner side between the two mounting blocks. The width between the inner sidewalls of the two mounting blocks is adapted to the length of the flip-top box, and the front end of the inner sidewall of the two mounting blocks can be designed as a slope, so that the front end of the mounting groove forms a guiding flare. The limiting blocks are used to limit the depth of the flip-top box pushed into the mounting groove. The protrusion is a radial rib provided on the inner side of the mounting block, and the radial rib and the mounting block form an integral L-shaped hook body. Furthermore, the mounting blocks and limiting blocks are modular components fixedly installed on the turntable, and can be installed by bolts. Several screw holes or elongated holes are machined on the turntable for installation, so that the position of the mounting blocks and limiting blocks can be finely adjusted, so as to change the size of the mounting groove by adjusting the position of the mounting blocks and limiting blocks, so that the system can be adapted to flip-top boxes of different sizes.

[0055] The lid-opening robot assembly is an automated component that opens and maintains the open state of a closed, inverted, gripped flip-top box, as well as closes the lid. This robot assembly is installed at each loading station, driving the flip-top boxes and lids to open, maintain, and close throughout the filling process. Please refer to [link / reference]. Figure 6 The lid-opening robotic arm assembly includes a lid-opening swing arm 1-6, a lid-opening swing shaft driver 1-7, and a lid-opening suction cup 1-8. The lid-opening swing arm is mounted on the lid-opening swing shaft driver and is driven by the lid-opening swing shaft driver to swing its end, on which the lid-opening suction cup is mounted. The swing trajectory of the lid-opening suction cup is adapted to the opening trajectory of the box lid being held. Specifically, the lid-opening swing shaft driver is a power output component that can drive a shaft to rotate around its own axis. It can be a servo motor or a pneumatic motor. In this embodiment, the lid-opening swing shaft driver is a pneumatic motor fixedly mounted on a flat turntable. A small gear transmission box is mounted at the front end of the pneumatic motor as a transmission extension. The gear transmission box is a known component in the mechanical field. The gear transmission box has a lid-opening swing shaft 1-9 located below the flat turntable. The lid-opening swing arm is mounted on the lid-opening swing shaft and achieves the swinging action by rotating around the lid-opening swing shaft. In this embodiment, specifically, the axis of the opening swing shaft is coaxial with the flip axis of the flip-top box lid being positioned, ensuring that the swing trajectory of the opening suction cup matches the opening trajectory of the box lid, allowing the opening suction cup, which engages with the lid, to open and close the lid. The opening swing arm includes an arm connected to the opening swing shaft and a claw arm connected to the outer end of the arm arm, parallel to the axis of the opening swing shaft. The opening suction cup is a pneumatic suction cup mounted on the claw arm. After being driven by the opening swing shaft driver to move to the upper surface of the flip-top box lid, it uses the resulting vacuum pressure to vacuum-grip the lid. The pneumatic suction cup is a known component.

[0056] For pneumatic suction cups, the material of the suction part should be flexible to reduce the risk of surface damage. The suction cup material should have a certain degree of softness and wear resistance, avoiding scratches that may be caused by using hard materials. Additionally, adding a soft coating, such as rubber or silicone, to the suction cup surface reduces friction between the suction cup and the substrate surface. These coatings provide better adhesion while reducing surface damage. Design the shape and structure of the suction cup to maximize its contact area with the substrate surface, thereby reducing pressure per unit area. Avoid using sharp edges or protrusions to reduce localized pressure. Adjust the suction strength of the vacuum system to be strong enough to maintain the stability of the substrate, but not so strong as to cause surface deformation or damage. Modern vacuum systems typically have adjustable suction control. Introduce sensors and feedback systems at appropriate locations to monitor the state between the suction cup and the substrate surface. If abnormalities occur, such as over-adhesion or surface deformation, the system can adjust or stop operation in time to avoid damage. Regularly inspect and maintain the suction cup to ensure its good condition. Periodically replace severely worn suction cups or coatings to maintain adhesion performance and prevent surface damage.

[0057] The rotary table conversion mechanism includes a closing transition plate 1-10, which is located between the carton filling mechanism and the carton discharging mechanism. The closing transition plate is positioned below the arc-shaped movement trajectory of the loading station on the rotary table and is used to support the cigarette packs filled in the carton. After the cigarette packs are tightly filled into the inverted flip-top carton, it is difficult to guarantee that they will not loosen or fall off during the movement from the filling station to the discharging station, or before the lid is completely closed. Therefore, a closing transition plate is installed between the carton filling mechanism and the carton discharging mechanism to ensure that the upper surface of the closing transition plate effectively supports the cigarette pack during the movement of the flip-top carton from the filling station to the discharging station, preventing it from falling off. The closing transition plate ends near the carton discharging mechanism, and at this position, the lid of the flip-top carton has been driven to a near-completely closed state by the opening robot assembly and will continue to be controlled to complete the closure.

[0058] The aforementioned flat-rotation station conversion mechanism has the functions of inverting and clamping the flip-top carton, changing its position, and opening and closing the lid during clamping and position conversion, which can meet the filling requirements of basic flip-top cartons. However, some flip-top cartons also have other accessories, such as a film extending from the side of the carton to cover the inner cavity. This film is used to cover the cigarette packs filled inside the carton, so it needs to be opened before filling and closed after filling. In addition to the above accessories, to prevent the flip-top carton from becoming damp and deformed, it usually contains a desiccant, which is placed in a bag inside the carton and needs to be removed before filling the cigarette packs.

[0059] Based on the above requirements, this flat-rotation station conversion mechanism has the following further design features.

[0060] The rotary table conversion mechanism includes a film-flipping robot assembly, which is used to automatically flip and cover the film inside the flip-top box. Its structure and working principle are the same as the aforementioned lid-opening robot assembly. Specifically, the film-flipping robot assembly is installed on the rotary table, and each assembly corresponds to a clamping station and is located to the side of that station. That is, the lid-opening robot assembly and the film-flipping robot assembly for the same clamping station are located on opposite sides of that station.

[0061] Please see Figure 5 The film-flipping robot assembly includes a film-flipping swing shaft driver 1-11, a film-flipping swing rod 1-12, and a film-flipping suction cup 1-13. The film-flipping swing shaft driver is mounted on a flat turntable. The film-flipping swing shaft driver is a power output component that can drive a shaft to rotate around its own axis. In this embodiment, the film-flipping swing shaft driver uses the same component structure as the lid-opening swing shaft driver. Depending on the different directions of the lid and film-flipping axis of the flip-top box, the axis of the film-flipping swing shaft driver is perpendicular to the axis of the lid-flipping axis. Because the film is a flexible film, the position of the film-flipping axis is not strictly limited. The film-flipping swing rod is mounted on the film-flipping swing shaft driver and is driven to swing. The film-flipping suction cup is mounted on the swing end of the film-flipping swing rod, and the suction cup has an arc-shaped movement trajectory adapted to the film-flipping trajectory in the box. The film-flipping lever includes a radial rod section, a shaft section, and an end rod section. The shaft section is parallel to the rotating shaft of the film-flipping lever shaft driver. The radial rod section and the end rod section are connected through the shaft section and are perpendicular to the shaft section. The film-flipping suction cup is also a pneumatic suction cup. The operating principle of the film-flipping lever and the film-flipping suction cup in holding and flipping the film inside the flip-top box is the same as that of the opening robot assembly.

[0062] The film-flipping robot assembly needs to flip the film at a sufficient angle to ensure smooth filling. The film-flipping swing arm will move above the cap-closing transition tray. To prevent interference between the movement of the film-flipping swing arm and the cap-closing transition tray, and to ensure that the film can be closed using the cap-closing transition tray during the movement of the flipped strip box towards the unloading station after filling, in this embodiment, the cap-closing transition tray is an arc-shaped flat tray whose curvature matches the movement trajectory of the loading station. Please refer to [link to relevant documentation]. Figure 7The closing transition tray includes a front tray 1-101 near the carton filling mechanism and a rear tray 1-102 near the carton discharging mechanism. The front tray is mounted on a tray driver 1-103, which drives the front tray to move and creates a swing space for the film-flipping swing arm. Specifically, the tray driver is a horizontal linear module. The tray driver drives the front tray to move away from the flat turntable, providing sufficient swing space below the film-flipping swing arm. The film-flipping swing arm causes the lower part of the film to swing down to below the front tray and releases the suction. The tray driver then drives the front tray to reset, and the carton begins to move horizontally towards the discharging station. During this movement, the film is pressed between the closing transition tray and the cigarette pack by the pushing action of the closing transition tray, achieving film coverage.

[0063] In addition to the aforementioned cover-closing transition tray, a similarly functional film-coating tray 1-14 is provided between the feeding station and the desiccant discharge station of the rotary table conversion mechanism. This film-coating tray is an arc-shaped flat plate adapted to the movement trajectory of the clamping station and located below the moving rail of the clamping station. After the lid of the flip-top box is opened at a small angle by the opening robot assembly, the rotary table begins a station conversion. The inverted flip-top box moves from the feeding station to the desiccant discharge station. During this movement, the film-coating tray always supports the film under the box. The film-coating tray ends before the flip-top box moves to the desiccant discharge station, and the opening robot assembly fully opens the box after it moves to the desiccant discharge station. At this station, the film is fully opened by the flip-top robot assembly, and the desiccant bag in the flip-top box falls and is discharged under gravity. A special desiccant recovery box can be placed below this station.

[0064] The above structure is the specific structure and working principle of the flat-rotation station conversion mechanism in this application. This flat-rotation station conversion mechanism has the functions of clamping the carton, moving it horizontally, and opening and closing the lid during the horizontal movement, which are the basic functions required for filling. It can also be equipped with other components to provide functions such as film opening and closing and desiccant discharge, providing action support for the inverted filling of the flip-top carton. Taking the movement steps of a flip-top carton as an example, firstly, the flip-top carton clamped at the feeding station in the flat-rotation station conversion mechanism rotates 90° in the horizontal plane through this mechanism and enters the desiccant discharge station. Automatic components such as the lid-opening robot component make the carton fully open, and the desiccant falls out and is discharged. Then, by intermittently rotating 90°, it passes through the filling station and the discharge station in sequence, and in the process, the automatic components such as the lid-opening robot component complete the closing of the flip-top carton.

[0065] The carton feeding mechanism is an automated mechanism that moves empty flip-top cartons from the feeding conveyor belt to the corresponding loading station in the aforementioned horizontal rotation station conversion mechanism. Please refer to [link to relevant documentation]. Figure 8 and Figure 9The carton feeding mechanism includes a carton feeding support component 2-1 and a feeding pusher assembly. The carton feeding support component has a feeding support end face for supporting the carton in an inverted state, and the support end face is located on the side of the turntable.

[0066] The feeding and pushing assembly includes a feeding push rod 2-2 and a feeding driver 2-3 that drives the feeding push rod. The carton feeding support component can be a flip-top carton conveyor belt or an independent support platform. The feeding and pushing assembly is an automated component that horizontally pushes the flipped carton from the carton feeding support component to the loading station of the station conversion mechanism.

[0067] In this embodiment, specifically, the carton feeding mechanism includes carton stacking boxes 2-4. The carton stacking boxes have stacking slots for accommodating vertically stacked cartons, a stacking inlet located at the top of the stacking slots, and a stacking outlet located at the bottom of the stacking slots. Specifically, the carton stacking boxes have a frame structure with vertically extending side plates on both sides. The side plates are L-shaped plates in cross-section. The side away from the horizontal rotation station conversion mechanism forms an opening for the flip-top cartons to enter laterally, while the opening on the side closer to the horizontal rotation station conversion mechanism is narrower, used to limit the entry of the flip-top cartons. A flat linear conveyor belt for conveying the flip-top cartons is opposite the front of the carton stacking box, and the conveying direction is directly opposite the opening of the carton stacking box. The inverted flip-top cartons conveyed by the flat linear conveyor belt enter the stacking slots of the carton stacking box and fall sequentially to form a stacked state. The carton feeding support component is a flat plate located below the stacking outlet, on which the stacked flip-top cartons fall and are supported. The upper front of the carton feeding support component forms a feeding port opposite to the mounting station of the horizontal rotation station conversion mechanism. This feeding port is formed by the bending plate structure of the L-shaped side plate, and its two layers still have downward extensions for limiting the flip-top carton. A feeding pusher assembly is provided at the upper rear of the carton feeding support component. In this embodiment, specifically, the main body of the feeding pusher assembly is a horizontal linear module, on which a feeding pusher plate driven by this horizontal linear module to move horizontally and linearly is mounted. The feeding pusher plate is the aforementioned feeding push rod. The feeding pusher plate moves horizontally and linearly along the width direction of the flip-top carton, thereby pushing the lowest layer of flip-top carton in the stacked state into the mounting station. The thickness of the feeding pusher plate is less than the unit thickness of the flip-top carton to ensure that only one carton is pushed at a time.

[0068] The carton filling mechanism is an automated mechanism used to vertically push rows of cigarette packs into an inverted, rotating carton from bottom to top. It is installed between the cigarette pack conveyor belt and the horizontal rotation station conversion mechanism. Please refer to [link / reference]. Figure 10 and Figure 11The carton filling mechanism includes a carton lifting and filling tray 3-1 and a filling and lifting assembly. The lifting and filling tray is used to receive and support a row of cigarette packs arranged from the cigarette pack conveyor belt. The filling and lifting assembly is a driving component or assembly that applies a vertical driving force to the lifting and filling tray. Specifically, the carton lifting and filling tray has a filling support end face for supporting the cigarette packs, which is a support plane located below the turntable. The filling and lifting assembly includes a filling push rod and a filling driver 3-2 that drives the filling push rod. The filling push rod is used to push the cigarette packs above the filling support end face into the carton from bottom to top. In this embodiment, the filling driver is a vertical linear module, and the connecting member between the vertical moving part of the vertical linear module and the lifting and filling tray is the filling push rod.

[0069] For the method of transferring cigarette packs from the cigarette pack conveyor belt to the lifting and filling pallet, this technical solution designs a dedicated automated component, namely the carton filling mechanism, which includes a cigarette pack pushing component. The cigarette pack pushing component is located on the side of the carton lifting and filling pallet and is used to push the transverse line of the cigarette pack on the cigarette pack conveyor belt, which is parallel to the length direction of the flip-top carton in the filling state, to the lifting and filling pallet.

[0070] The cigarette pack flat-push assembly includes a cigarette pack feeding tray 3-3, a cigarette pack flat-push frame 3-4, a cigarette pack flat-push plate 3-5, a cigarette pack flat-push driver 3-6, and a flip-plate driver 3-7. The cigarette pack feeding tray is located to the side of the carton lifting and filling tray and serves as the supporting plane at the end of the cigarette pack conveyor belt. The cigarette packs are conveyed by the cigarette pack conveyor belt, which provides the pushing force. The cigarette packs are pushed onto the cigarette pack feeding tray to form a single-layer arrangement. The number of packs that the cigarette pack feeding tray supports at one time is the number of single-layer filling packs of the flip-top carton.

[0071] The cigarette pack pusher is positioned above the cigarette pack feeding tray. It is the main moving component in the cigarette pack pushing assembly, responsible for pushing the cigarette packs. It moves horizontally above the cigarette pack feeding tray and the lifting filling tray. A cigarette pack pusher driver is connected to the pusher, driving it to move horizontally along a direction perpendicular to the axis of the flip-plate shaft. In this embodiment, the pusher driver is a horizontal linear module, located to the side of the horizontal rotation station conversion mechanism, and can be mounted on an independent bracket or a system bracket assembly. The cigarette pack pusher is mounted on the horizontal linear module and used as a carrier to drive its horizontal linear movement.

[0072] In this embodiment, specifically, the cigarette pack pusher is a horizontal plate component. During its horizontal linear movement, it remains above the cigarette packs positioned on the cigarette pack feed tray, and the pusher itself does not contact the cigarette packs. The cigarette pack push plate, as an accessory to the pusher, is installed on the pusher and is the actuating component that contacts the rear side of the rows of cigarette packs, pushing them forward. The push plate is mounted on the pusher via a flip-plate shaft 3-8, which is horizontally positioned and perpendicular to the direction of movement of the pusher. The flip-plate driver is connected to the push plate and drives it to rotate around the flip-plate shaft. In this embodiment, specifically, an arm is formed at the rear of the shaft hole of the cigarette pack pusher plate. The flip-plate driver is a cylinder, which is installed on the cigarette pack pusher frame. The piston rod of the cylinder is connected to the arm at the rear of the cigarette pack pusher plate via a connecting rod. The cylinder drives the cigarette pack pusher plate to swing and flip around the flip-plate shaft through the extension and retraction of the piston rod. The swinging and flipping cigarette pack pusher plate forms a swinging plate component that swings downwards towards the front of the cigarette pack pusher plate. When the cigarette pack pusher plate is swinging downwards, its horizontal linear movement will push the cigarette pack. When the cigarette pack pusher plate is flipped and in a swinging and lifted state, its horizontal linear movement will not contact the cigarette pack. That is, in this state, the gap between the cigarette pack pusher plate and the cigarette pack feed tray is greater than the thickness of the cigarette pack. In this mechanism, the design of the cigarette pack flat push plate with a flipping function is to ensure that after a group of cigarette packs is pushed to the top filling tray, during the return process of the cigarette pack flat push frame and the cigarette pack flat push plate, the lifting action of the cigarette pack flat push plate can create space above the cigarette pack feeding tray for continued feeding of cigarette packs. This ensures that the return process of the cigarette pack flat push frame and the cigarette pack flat push plate can be synchronized with the cigarette pack feeding process, thereby improving the operating efficiency of the equipment.

[0073] The rear of the cigarette pack feeding tray is equipped with a cigarette pack limiting plate 3-9, which has spaced-apart stacking openings. The cigarette pack pusher plate has teeth that can pass horizontally through the stacking openings. This design ensures reliable positioning of the cigarette packs on the cigarette pack feeding tray and guarantees that the cigarette pack pusher plate can push the cigarette packs horizontally and linearly from behind the cigarette pack limiting plate.

[0074] Some flip-top carton boxes also have other accessories, such as a long, narrow ribbon that spans the bottom of the inner cavity. This ribbon needs to be pressed against the bottom of the cigarette pack to facilitate its removal. Therefore, it needs to be pulled and pressed to the bottom of the inner cavity of the carton before filling. Based on the above requirements, this carton filling mechanism is also designed with the following automated components with auxiliary functions.

[0075] Please see Figure 13The system includes a belt pull assembly 5, which is positioned above the carton feeding mechanism. The belt pull assembly includes a pull rod 5-1, a hook plate 5-2, and a belt pull driver 5-3. The hook plate is a vertical strip parallel to the inner wall of the long side of the carton in the filling state. The hook plate is located at the front end of the pull rod, which is a horizontal rod parallel to the direction in which the cigarette pack is pushed horizontally and linearly. In this embodiment, the hook plate and pull rod are formed by bending a long strip of metal at a right angle. The pull rod is mounted on the belt pull driver, which drives the pull rod to reciprocate in a vertical plane. Specifically, the belt pull driver functions to drive the hook plate to perform horizontal linear feeding at a low position, vertical lifting, and horizontal linear return pulling / pressing actions at a high position. In this embodiment, the belt pull driver is a right-angle module composed of a vertical linear module and a horizontal linear module, serving as a dual-axis drive component, which is a conventionally known component.

[0076] The aforementioned pull-belt assembly and carton filling mechanism work as follows: A single row of cigarette packs is pushed horizontally from the cigarette pack feeding tray to the carton lifting and filling tray by the cigarette pack pushing assembly. Then, the filling and lifting assembly drives the packs to be lifted and filled into the inverted, fixed-position, open-top carton. Before the cigarette packs are lifted into the carton, the pull-belt assembly has already pulled and pressed the ribbons in the carton against the inner wall of the carton through a low-position horizontal linear feed, vertical upward lifting, and high-position horizontal linear return pull-press action, ensuring that the ribbons are pressed under the cigarette packs after they enter the carton. This mechanism has independent basic cigarette pack filling functions of pushing and lifting, and can serve as a basic filling unit in an inverted filling system for cartons.

[0077] In addition to designing the aforementioned pull strap assembly to provide the mechanism with corresponding auxiliary functions, in this embodiment, to further ensure that the cigarette pack is aligned and enters the slot of the carton during its vertical movement as it is lifted and pushed towards the flip-top carton, the mechanism includes a cigarette pack filling guide assembly 6. Please refer to... Figure 12 Specifically, this includes a rectangular guide frame 6-1, located directly above the pack lifting and filling tray. The inner dimension of the rectangular guide frame is slightly larger than the opening of the flip-top pack. Inside the guide frame is a guide plate 6-2 with an expanding elasticity, wider at the bottom and narrower at the top. This elasticity can be achieved through the material elasticity of the guide plate itself, or through the installation method of the guide plate frame, whereby the guide plate is hinged to the inside of the guide frame via a transverse pin fitted with a coil spring. The rectangular guide frame is installed on a linear module that drives its vertical movement. Before the pack is pushed into the flip-top pack, it forms a flared guide structure below the opening of the flip-top pack by moving vertically upwards. The outer edge of the rectangular guide frame needs to be designed with a notch for the hook plate to move and allow space.

[0078] The carton unloading mechanism is an automated structure that pushes the closed, flipped carton (filled with cigarette packs) from the unloading station of the rotary station conversion mechanism to the output conveyor belt located on the side of the rotary station conversion mechanism. For details, please refer to [link to details]. Figure 14 The carton dispensing mechanism includes a dispensing pusher assembly, which includes a dispensing push rod 4-1 and a dispensing driver 4-2 that drives the dispensing push rod. In this embodiment, the entire carton dispensing mechanism is located inside the loading station of the station conversion mechanism. The carton pusher assembly is a module drive assembly composed of a vertical linear module and a horizontal transverse module. The two module drive assemblies work together to drive the dispensing push rod mounted on them to move vertically and horizontally in a coordinated manner to complete the vertical cyclic action of rising, pushing horizontally, falling, and resetting. The vertical movement is to make way for the related movements of the horizontal station conversion mechanism and avoid interference.

[0079] The aforementioned linear module is a standard component with linear drive function in the current mechanical field. For example, the module drive assembly composed of the aforementioned vertical linear module and horizontal transverse module is a conventional working assembly method, which aims to realize the movement of components in the vertical plane of the XZ axis.

[0080] In this embodiment, before the lid of the flip-top carton is closed, the excess end of the ribbon needs to be covered over the cigarette pack of the flip-top carton, after which the lid of the flip-top carton is closed. Therefore, a pusher assembly 7 is provided before the carton filling mechanism and the lid-closing transition plate. Please refer to [link to relevant documentation]. Figure 13 The pusher assembly includes a pusher driver 7-2 and a horizontal pusher plate 7-1. The horizontal pusher plate is a flat strip with a small thickness. The pusher driver is a horizontal linear module. The horizontal linear module drives the horizontal pusher plate to extend and retract horizontally back and forth, so as to push and fold the excess end of the ribbon exposed inward and flatten it over the cigarette pack before the flip-top carton is fully inserted into the closing transition tray, so that it can be supported by the closing transition tray and finally closed on the inside of the box lid.

[0081] In summary, through innovative design and development, we have introduced an innovative technical solution for the automated filling of flip-top cartons—the flat-rotation flip-top carton filling system—to fill the gap in existing technology. This system fundamentally solves a series of problems caused by manual filling, and its flat-rotation station transition method brings many significant advantages and effects.

This helps eliminate damage and misalignment caused by unstable carton movement, ensuring the quality and consistency of the filling process and improving the product's appearance and packaging quality. Finally, we are committed to improving packaging quality. The flat-top flip-top carton filling system not only ensures accurate filling and sealing of the cartons but also features additional functions such as laminated flip-tops, ribbon tensioning, and desiccant removal. These measures ensure full utilization of packaging materials, maintain stable quality, and further improve overall packaging quality. In summary, our flat-top flip-top carton filling system offers a series of advantages and benefits, including a compact structure, improved operational efficiency, stable carton movement, and enhanced packaging quality. This technology not only solves the challenges in producing rigid flip-top cartons but also significantly improves production efficiency, reduces costs, and ensures product quality and consistency.
