Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a vertical cigarette packing and sealing system. Background Technology

[0002] Currently, the tobacco industry faces numerous pain points in the packing and sealing of cigarette cartons. Cartons produced by packaging machines need to be transported one by one to the packing and sealing area via an overhead conveyor line to complete the packing and sealing process. However, the packaging machine area and the packing and sealing area are far apart, and the overhead conveyor line easily scratches the appearance of the cigarette cartons during transport, affecting product quality. Furthermore, the large volume of cigarette cartons creates significant inconvenience for on-site management. Even more problematic is that the supply of box blanks in the packing and sealing area relies entirely on manual operation. Workers need to frequently call for materials and move the box blanks to the box blank loading station of the packing and sealing machine. This work is not only low in technical content but also time-consuming and labor-intensive, significantly reducing production efficiency, increasing labor intensity, and hindering modern production management. In addition, although the packing and sealing area is adjacent to the packaging area, the packing and sealing area occupies a large separate floor space, mainly used for placing existing equipment. Without changing the production site, companies cannot increase production capacity by adding cigarette rolling machines and packaging machines, which severely restricts the company's production scale and development potential. Summary of the Invention

[0074] Example 1:

[0075] Please refer to Figure 1-31 As shown, this embodiment provides a vertical cigarette packing and sealing system, including an automatic replacement device 12, a box-moving robot 13, a vertical packing and sealing machine, and a central control system; the central control system is connected to the automatic replacement device 12, the box-moving robot 13, and the vertical packing and sealing machine by signal; the signal connection methods include electrical connection, optical connection, or wireless connection, etc.

[0076] The automatic replacement device 12 has an upper layer and a lower layer. The upper layer of the automatic replacement device 12 is used to receive the blank pallet. After the blank is used, the automatic replacement device 12 can transfer the empty pallet to the lower layer of the automatic pallet replacement device 12 for receiving new blank pallets.

[0077] The box-moving robot 13 is used to identify box blanks on the pallet and place them one by one into the carton warehouse 2. After the box blanks on the pallet are used up, the box-moving robot 13 can send a material call signal and an empty pallet switching signal to the central control system to achieve continuous automatic material supply.

[0078] The vertical carton sealing machine includes a main frame 1, and a carton warehouse 2, a cigarette inlet belt conveyor 3, an automatic cigarette stacking and turning device 4, a cigarette stack box entry and folding device 5, a lifting drive mechanism 6, an electric sealing belt device 7, a roller conveyor 8, a box pushing mechanism 9, a sliding box turning mechanism 10, and an emergency exit lifting roller machine 11.

[0079] The main frame 1 of this embodiment provides installation and connection positions for various devices, mechanisms, and components. The main frame 1 has a stacking station A1, a pushing station A2, a storage station A3, a boxing station A4, a sealing station A5, a lifting station A6, and a box-flipping station A7. The stacking station A1 is located on one side of the pushing station A2; the boxing station A4 is located between the pushing station A2 and the storage station A3; the lifting station A6 is located above the boxing station A4; the sealing station A5 is located between the boxing station A4 and the lifting station A6; and the lifting station A6 is located on one side of the box-flipping station A7.

[0080] The cardboard box warehouse 2 is located at the storage station A3 and is connected to the box-moving robot 13 to provide box blanks;

[0081] The cigarette inlet conveyor belt 3 is connected to the automatic cigarette stacking and turning device 4, which is located between the stacking station A1 and the pushing station A2. The cigarette inlet conveyor belt 3 receives the cigarettes output from the packaging machine and transports them to the automatic stacking and turning device, which stacks and turns the cigarettes into a vertical stack of cigarettes in the arrangement required for boxing.

[0082] The tobacco stack loading and folding device 5 is installed at the packing station A4. The tobacco stack loading and folding device 5 is used to unfold the box blank into an upright carton, load the tobacco stack into the box and fold the box pages into shape.

[0083] The lifting drive mechanism 6 is vertically arranged and connects the packing station A4 and the lifting station A6. It is used to transport the upright cigarette box from the packing station A4 to the lifting station A6, so as to directly lift the upright cigarette box to the height required for the overhead conveyor. The electric sealing tape device 7 is set at the sealing station A5 and uses transparent tape to seal the openings formed on both sides of the upright cigarette box to achieve the sealing of the carton.

[0084] Roller conveyor 8 is connected to the lifting station A6. Emergency outlet 81 and downstream docking interface 82 are formed at both ends of roller conveyor 8, respectively. The flipping station A7 is formed between the lifting station A6 and the downstream docking interface 82. The pushing mechanism 9 is set at the lifting station A6 and is used to push the upright cigarette box into the roller conveyor 8. The sliding flipping mechanism 10 is set at the flipping station A7 and is used to flip the upright cigarette box into a horizontal cigarette box so that the roller conveyor 8 can smoothly transport the finished cigarette box. The lifting roller of the emergency outlet 81 is set at the emergency outlet 81 and is used to receive the finished cigarette box through the emergency outlet lifting roller machine 11 and lower it to the manual handling station when the rear overhead conveyor line fails, so as to facilitate manual handling.

[0085] The vertical cigarette packing and sealing system in this embodiment adopts a vertical packing and sealing process, replacing the traditional horizontal packing and sealing process. This allows finished cigarette cartons to directly enter the overhead conveyor line after the packing and sealing process. This change not only cleverly reduces the overall footprint of the equipment but also realizes the transformation from pack cigarette transportation to finished cigarette carton transportation, significantly reducing the internal logistics flow of the workshop and optimizing the spatial layout and logistics efficiency of the production site. By introducing a carton-moving robot 13 for operation in the carton blank feeding stage, and equipping it with an automatic pallet replacement device 12, this combination achieves fully automated functions of automatic carton blank feeding, automatic material calling, and automatic switching of empty pallets, greatly improving the efficiency of material pallet replacement and significantly increasing the automation level of the production site. The sealed finished cigarette cartons can be directly connected to the overhead conveyor line, realizing full automation from the replenishment of carton warehouse 2 to the final carton output, without manual intervention. This highly automated, efficient, and compact vertical cigarette packing and sealing system not only brings innovation to the tobacco industry's production mode but also provides a highly valuable solution for the automation upgrade of similar industries, demonstrating its broad application prospects and far-reaching industry influence. These intelligent improvements not only enhance work efficiency but also effectively reduce labor input, significantly lowering the workload of operators and making the production process easier and more efficient. The compact and innovative structural design facilitates easy maintenance and occupancy, effectively reducing investment costs.

[0086] Please refer to Figure 2-5 As shown, the automatic replacement device 12 in this embodiment consists of two symmetrically arranged pallet transfer racks 121 and a limiting connecting frame 122 connecting the two sets of pallet transfer racks 121. The symmetrically arranged pallet transfer racks 121 enable effective separation and storage of blank pallets and empty pallets. The two sets of pallet transfer racks 121 are symmetrically distributed in space and interconnected by the limiting connecting frame 122, ensuring the stability and coordination of the overall structure.

[0087] The pallet transfer rack 121 includes a pallet base plate 1211 and a pallet outer frame 1212. The pallet outer frame 1212 is mounted on the pallet base plate 1211. The internal space formed by the pallet base plate 1211 and the pallet outer frame 1212 provides installation space for various mechanisms. The pallet transfer rack 121 is equipped with an upward tilting assembly 1213, an upward tilting drive assembly 1214, a downward tilting assembly 1215, and a downward tilting drive assembly 1216.

[0088] The tilting assembly 1213 includes a tilting shaft, a tilting arm, a tilting plate, and a tilting plate bearing seat; multiple arc-shaped tilting arms are mounted on the tilting shaft to provide mounting positions for the tilting plate; multiple tilting plate bearing seats mounted on the pallet bottom plate 1211 provide support for the tilting shaft; the tilting drive assembly 1214 includes a servo motor, a planetary reducer, a drive wheel, and a driven wheel; wherein the servo motor is connected to the drive wheel through the planetary reducer, and the drive wheel meshes with the fan-shaped driven wheel; the rotation center of the driven wheel is connected to one end of the tilting shaft.

[0089] The tilting assembly 1215 includes a tilting shaft, tilting arms, a tilting plate, and a tilting shaft support plate. Multiple L-shaped tilting arms are mounted on the tilting shaft to provide mounting positions for the tilting plate. Multiple tilting shaft support plates mounted on the pallet bottom plate 1211 provide support for the tilting shaft. The tilting drive assembly 1216 also includes a servo motor, a planetary reducer, a drive wheel, and a driven wheel. The servo motor is connected to the drive wheel through the planetary reducer, and the drive wheel meshes with the fan-shaped driven wheel. The rotation center of the driven wheel is connected to one end of the tilting shaft.

[0090] Two sets of positioning rings are installed on both the upper and lower tilting shafts. The upper tilting shaft and the lower tilting shaft are clamped by the upper tilting plate bearing seat and the lower tilting shaft support plate to position the upper and lower tilting shafts. At the end of the upper and lower tilting shafts away from the driven wheel, there is a fan-shaped photosensitive film. With the corresponding slotted switch, it can detect whether the rotation of the upper and lower tilting plates is in place. Multiple sensors are installed on the outer frame 1212 of the pallet to detect whether the auxiliary material pallet is delivered in place by the automated guided vehicle (AGV) or manual forklift and whether the empty pallet is lowered in place.

[0091] Please refer to Figure 6As shown, the box-moving robot 13 in this embodiment includes a robot base 131, on which a robotic arm 132 is mounted, and a robot industrial control computer 133 is installed inside. The robot industrial control computer 133 is connected to the central control system and is responsible for controlling the box-moving robot 13 to perform the box blank loading process. A clamp base plate 134 is mounted on the execution end of the robotic arm 132. Two sets of integrated vacuum suction cups 135 are mounted on the bottom of the clamp base plate 134. The two sets of integrated vacuum suction cups 135 are responsible for adsorbing and releasing the box blanks and transferring the box blanks from the auxiliary material pallet to the carton warehouse 2. A clamp guard is provided above and around the two sets of integrated vacuum suction cups 135. The clamp guard is responsible for enclosing the clamp part to ensure the personal safety of the surrounding personnel as much as possible.

[0092] Please refer to Figure 7-8 As shown, the main frame 1 of the vertical box packing machine in this embodiment is composed of several welded square tubes. Each component is arranged on the main frame 1 by welding the mounting plates of each component to the main frame 1. The hinges and door panels serve as windows for manual processing of the internal mechanisms. The main frame 1 provides the installation foundation for the above-mentioned devices and mechanisms.

[0093] Please refer to Figure 9-10 As shown, the vertical carton sealing machine in this embodiment is equipped with a carton storage compartment 2, which is located at the material storage station A3 and is used to provide carton blanks.

[0094] Specifically, the carton storage unit 2 includes a storage frame 21, which provides installation positions for other components of the carton storage unit 2. A storage station A3 is formed on the storage frame 21, with a replenishment inlet and a supply outlet at each end. The replenishment inlet is used by the carton-moving robot 13 to fill the storage station A3 with carton blanks, and the supply outlet is used to connect with the cigarette stack loading and folding forming device 5 to supply carton blanks. The carton storage unit 2 also includes a belt conveyor 22, a material blocking assembly 23, a carton pressing mechanism 24, an upper carton blocking mechanism 25, and a lower carton blocking mechanism 26.

[0095] The belt mechanism 22 is located at the bottom of the storage station A3. The belt mechanism 22 is used to support the blank in the storage station A3 and provide power to transport the blank towards the feeding outlet.

[0096] Two sets of baffle components 23 are set on both sides of the storage station A3. The baffle components 23 include an inner baffle and an outer baffle. The two sets of baffle components 23 are symmetrically arranged and designed with bevels, which facilitates the placement of box blanks by the box-moving robot 13, while also isolating the internal transmission parts, protecting the personal safety of the staff, and providing a foundation for the installation of sensors.

[0097] A pressing mechanism 24 is mounted on the material blocking assembly 23. The pressing mechanism 24 includes a rear pressing plate that can slide relative to the box storage frame 21. The rear pressing plate applies a pressing force to the box blanks in the storage station A3, pointing towards the material supply outlet. The pressing mechanism 24 is equipped with an upper box end photosensitive film, which cooperates with an upper box end slotted switch mounted on the inner baffle to control the extreme positions of the servo motor. A diffuse reflection sensor is mounted on the inner baffle to detect the remaining amount of box blanks. When the remaining amount is low, a material shortage signal is sent to the central control system, which then controls the box handling robot 13 to perform the box blank loading process.

[0098] The upper baffle mechanism 25 and the lower baffle mechanism 26 are respectively located on the upper and lower sides of the material supply outlet of the material storage station A3, and are used to intercept or release the lower and upper edges of the blank.

[0099] The upper box-blocking mechanism 25 is fixed on the main frame 1 and includes an upper pressing assembly and an upper box-blocking assembly. The upper box-blocking assembly is driven by a cylinder to swing the box-blocking plate, controlling the upper constraint and release of the first box blank in the storage station A3. The upper pressing assembly is driven by a cylinder to move the upper pressing block up and down, controlling the constraint and release of the other box blanks in the storage station A3 except for the first box blank. The lower box-blocking mechanism 26 is fixed on the box storage frame 21. It is driven by a cylinder to swing the lower swing plate, controlling the lower constraint and release of the first box blank in the carton storage 2. By setting lower box-blocking plates on both sides of the box storage frame 21, it controls the lower edge of the first box blank in the carton storage 2. When the cigarette stack loading and folding forming device 5 grabs the first box blank in the carton storage 2, it provides the constraint guide for the initial forming of the lower edge of the carton.

[0100] The carton storage frame 21 is equipped with a carton positioning swing plate and a carton positioning slot switch near the material supply outlet. Through the cooperation of the carton positioning slot switch and the carton positioning photosensitive film, it is detected whether the second carton blank has moved to the position of the first carton blank after the first carton blank in the carton storage 2 has left the carton storage 2.

[0101] Please refer to Figure 11 As shown, in this embodiment, the cigarette inlet conveyor belt 3 of the vertical packing and sealing machine has an input end 31 at its end. The input end 31 is used to receive flat cigarettes produced by the packaging machine. A lifting station 32 is formed on the inlet conveyor belt. The flat cigarettes are transported from the input end 31 to the lifting station 32 through the inlet conveyor belt.

[0102] The cigarette inlet conveyor belt 3 includes a conveyor frame 33, a geared motor, a transmission sprocket assembly, a belt, an adjusting frame, a cigarette support plate 34, guide plate brackets, guide plates, and a diffuse reflection sensor. The conveyor frame 33 is fixed to the main frame 1, providing support for all components of the cigarette inlet conveyor belt 3. The geared motor is installed at one end of the conveyor frame 33, driving the belt movement through the transmission sprocket assembly, thus realizing the function of conveying cigarettes. The adjusting frame is installed at the other end of the conveyor frame 33, responsible for tightening the belt and ensuring smooth belt operation. The cigarette support plate 34 is installed above the adjusting frame, used for docking with the packaging machine, responsible for supporting the cigarettes output from the packaging machine and transferring them to the cigarette inlet conveyor belt 3. Multiple guide plate brackets are evenly distributed on both sides of the conveyor frame 33, responsible for supporting and adjusting the guide plates, ensuring the guide plates are aligned with the belt. The cigarette packs on the platform provide a guiding function, and the position of the guide plate can be adjusted through the guide plate bracket to accommodate multiple specifications of cigarette packs. Multiple diffuse reflection sensors form a diffuse reflection sensor group, which is arranged at the lifting station 32. Each diffuse reflection sensor shines upward and is responsible for sensing whether the cigarette packs are in place. If one of the multiple sensors does not meet the blocking condition, it proves that the lifting and stacking condition is not met. If all sensors are blocked by the cigarette packs, the lifting and stacking condition is met after a certain delay. The automatic stacking mechanism 41 lifts the cigarette pack layer, causing it to detach from the cigarette pack inlet belt conveyor 3 and enter the downstream packaging process.

[0103] Please refer to Figure 12-16 As shown, the automatic stacking and flipping device 4 of the vertical packing and sealing machine in this embodiment includes an automatic stacking mechanism 41, a primary stacking mechanism 42 and a stack flipping mechanism 43.

[0104] The automatic stacking mechanism 41 is installed at the stacking station A1. The automatic stacking mechanism 41 is used to receive the flat cigarette packs sent by the inlet belt conveyor and stack the flat cigarette packs in the stacking station A1 to form a flat cigarette stack.

[0105] The first-level stacking mechanism 42 is used to transfer the flat tobacco stack to the tobacco stack flipping mechanism 43;

[0106] The tobacco stack flipping mechanism 43 includes a flipping drive 431 and a rotating frame 432. The rotating frame 432 can switch between a flat state and an upright state. The flat tobacco stack is received by the rotating frame 432 in the flat state. The flipping drive 431 drives the rotating frame 432 to switch to the upright state, so that the flat tobacco stack is flipped into an upright tobacco stack, and the upright tobacco stack is positioned at the stacking station A2.

[0107] Specifically, the automatic stacking mechanism 41 includes a stacking lifting structure 411 and a stacking slot structure 412.

[0108] The stacking and lifting structure 411 includes a lifting mounting frame 4111, a lifting assembly 4112, and a lifting drive assembly 4113. The lifting mounting frame 4111 is fixed to the bottom of the inlet conveyor belt. The lifting assembly 4112 includes a lifting connecting plate, a first lifting plate, and a second lifting plate. The lifting connecting plate is slidably connected to the lifting mounting frame 4111 via a slider guide mechanism, allowing the lifting connecting plate to move back and forth in the height direction relative to the lifting mounting frame 4111. The first and second lifting plates are respectively fixed to both ends of the lifting connecting plate. The lifting drive assembly 4113 is connected to the lifting connecting plate via a crank-connecting rod mechanism. The lifting drive assembly 4113 provides power to drive the lifting connecting plate to move back and forth in the height direction, causing the first and second lifting plates at both ends to lift the two ends of the flat cigarette packs, pushing the flat cigarette packs on the lifting station 32 upward into the stacking station A1.

[0109] The stacking slot structure 412 includes a stacking slot base plate 4121, a first stacking component 4122, and a second stacking component 4123. The stacking slot base plate 4121 is fixed to the bottom of the inlet conveyor belt. The first stacking component 4122 and the second stacking component 4123 are respectively arranged on both sides of the lifting station 32. The first stacking component 4122 and the second stacking component 4123 support the two ends of the flat cigarette pack and fix the flat cigarette pack in the stacking station A1.

[0110] The first stacking assembly 4122 includes a first side frame, and the second stacking assembly 4123 includes a second side frame. The first side frame and the second side frame are slidably connected to the stacking slot substrate 4121 via a second slider guide mechanism, thereby allowing the first side frame and the second side frame to move closer to or further away from the lifting station 32. A torsion plate translation assembly 4124 and a translation drive assembly are also fixed to the bottom of the stacking slot substrate 4121. The torsion plate translation assembly 4124 is drively connected to the translation drive assembly and is connected to the first side frame and the second side frame, respectively. Power is provided by the translation drive assembly, which drives the first side frame and the second side frame on both sides of the lifting station 32, i.e., the first stacking assembly 4122 and the second stacking assembly 4123, to move closer to or further away from each other simultaneously, to accommodate different types of cigarette packs.

[0111] The first stacking assembly 4122 in this embodiment further includes a wedge 4125, a pivot fixing seat 4126, and a tension spring 4127. The pivot fixing seat 4126 is connected to the first side frame, and the bottom of the wedge 4125 is connected to a pivot. The pivot is hinged to the pivot fixing seat 4126, thereby allowing the wedge 4125 to rotate relative to the first side frame. The wedge 4125 has a first position and a second position. The first position is the wedge 4125... 25 rotates to the stacking station A1 to support the end of the flat cigarette pack. The second position is when the wedge 4125 rotates to the outside of the stacking station A1 to make way for the flat cigarette pack to enter the stacking station A1 from the lifting station 32. One end of the tension spring 4127 is connected to the wedge 4125, and the other end is connected to the first side frame. The tension spring 4127 provides an elastic force to drive the wedge 4125 to reset from the second position to the first position.

[0112] The specific structure of the second stacking component 4123 is the same as that of the first stacking component 4122. The two are arranged opposite each other to support the two ends of the flat cigarette pack. This is understandable to those skilled in the art and will not be described in detail here.

[0113] In use, the stacking lifting structure 411 lifts both ends of the flat cigarette packs, causing the flat cigarette packs on the lifting station 32 to move upward. The lifting force drives the wedge block 4125 to rotate from the first position to the second position, clearing the passage so that the flat cigarette packs can smoothly enter the stacking station A1. Then, the wedge block 4125 quickly resets under the action of the tension spring 4127, the lifting station 32 descends, and the wedge block 4125 supports the end of the bottom layer of flat cigarette packs. As the stacking lifting structure 411 lifts the flat cigarette packs upward layer by layer, the flat cigarette packs are stacked in the stacking station A1.

[0114] The front end of the first and second side frames, that is, the end closest to the input end 31 of the inlet belt conveyor, can also be equipped with a guide limit plate 4128. The guide limit plate 4128 is L-shaped. The horizontal bottom edge of the L-shape is responsible for preventing the cigarettes that have not entered the lifting station 32 from being lifted during the lifting process of the flat cigarette packs, so as to prevent the cigarette packs from turning over. The vertical side of the L-shape is responsible for providing guidance for the flat cigarette packs at the edge during the lifting process, so that they can smoothly enter the stacking station A1.

[0115] The stacking trough structure 412 also includes a baffle assembly 23, which includes a front fixed baffle and a rear sliding baffle arranged sequentially along the conveying direction of the inlet belt conveyor. The front fixed baffle and the rear sliding baffle are respectively set at both ends of the stacking station A1, and the front fixed baffle and the rear sliding baffle support the two sides of the flat tobacco stack in the stacking station A1 to prevent the stack from falling apart.

[0116] The front fixed baffle is fixedly connected to the first side frame, and the rear sliding baffle is slidably connected to the stacking groove base plate 4121. The connection between the rear sliding baffle and the stacking groove base plate 4121 is also provided with a screw mechanism and a locking mechanism for adjusting the position of the rear sliding baffle. The screw mechanism and the locking mechanism drive the rear sliding baffle to slide on the stacking groove base plate 4121, so that the rear sliding baffle can move closer to or further away from the front fixed baffle. This controls the width of the stacking station A1 so that it can adapt to the stacking requirements of different specifications of cigarette stacks.

[0117] The bottom of the rear sliding baffle can extend into the lifting station 32, intercepting the horizontally placed cigarette packs and allowing them to gather within the lifting station 32. Alternatively, an interception mechanism can be installed to achieve the gathering of horizontally placed cigarette packs within the lifting station 32, as will be understood by those skilled in the art.

[0118] The primary stacking mechanism 42 of this embodiment includes a stacking mounting frame, a stacking drive component, a stacking upright plate, and a stacking plate assembly.

[0119] The top of the pusher plate is connected to the pusher mounting frame, and the bottom of the pusher plate is connected to the pusher plate assembly. The pusher drive is fixed to the pusher mounting frame and is implemented using a rodless cylinder to save space. The pusher drive is connected to the pusher plate for transmission. The pusher drive drives the pusher plate to move horizontally between the stacking station A1 and the tobacco stack turning mechanism 43. The pusher plate assembly pushes the flat tobacco stack on the stacking station A1 into the flat rotating frame 432.

[0120] The pusher plate assembly can switch between a folded state and an unfolded state. The pusher plate assembly includes a pusher plate 421, a pusher flap 422, and a flap drive 423. The pusher plate 421 is connected to the bottom of the pusher plate, the pusher flap 422 is hinged to the pusher plate 421, and the flap drive 423 is located at the bottom of the pusher plate. The flap drive 423 is connected to the pusher flap 422 via a swing arm. The flap drive 423 drives the pusher flap 422 to unfold or fold relative to the pusher plate 421. The purpose of this action is that after the pusher flap 422 and the pusher plate 421 are unfolded to the same plane and a set of cigarette stacks are pushed out, the pusher flap 422 folds upward during the return trip, which does not affect the automatic stacking mechanism 41's process of stacking cigarettes upward, reducing standby time and improving production efficiency.

[0121] The stack-turning mechanism 43 in this embodiment also includes a stack-turning mounting frame 433; the stack-turning mounting frame 433 is used to install the stack-turning mechanism 43 onto the main frame 1 and is responsible for providing installation positions for other parts on this mechanism. The rotating frame 432 is a frame structure composed of a top plate, a bottom plate, and side plates. A rotating arm is provided between the bottom plate and the side plates, and the rotating arm is hinged to the stack-turning mounting frame 433 via a rotating shaft, thereby allowing the rotating frame 432 to rotate on the stack-turning mounting frame 433.

[0122] The flipping drive 431 is implemented using a cylinder. The fixed end of the flipping drive 431 is hinged to the flipping mounting frame 433. The flipping drive 431 has an output end, namely the piston end. A swing arm is hinged to the piston end of the flipping drive 431. The other end of the swing arm is fixed to the middle of the rotating shaft of the rotating arm by a shrink sleeve. The extension and retraction of the flipping drive 431 drives the swing arm to swing, thereby causing the rotating shaft to rotate. The two ends of the rotating shaft are fixed to the rotating arm of the rotating frame 432 by shrink sleeves. Two bearings with seats are arranged in the gaps of the three sets of shrink sleeves to fix the rotating shaft, realizing the switching between the horizontal and vertical states of the rotating frame 432.

[0123] Furthermore, the stacking mounting frame 433 is provided with fixed side plates; when the rotating frame 432 is switched to the flat position, the fixed side plates and the rotating frame side plates are arranged opposite to each other on both sides of the rotating frame 432 to limit the two sides of the flat tobacco stack and prevent it from collapsing.

[0124] The rotating frame 432 has a push-in and a push-out on opposite sides. The push-in is on the side near the stacking station A1, through which the flat smoke stack is fed in. Opposite to it is the push-out, through which the upright smoke stack formed after flipping can be sent out.

[0125] The rotating frame 432 further includes a first blocking flap 434, a first blocking drive 435, a second blocking flap, and a second blocking drive; the first blocking flap 434 is hinged to the top plate of the rotating frame, the first blocking drive 435 is connected to the top plate of the rotating frame, the first blocking drive 435 has an output end, and the output end of the first blocking drive 435 is connected to the first blocking flap 434 through a swing arm; the second blocking flap is hinged to the bottom plate of the rotating frame, the second blocking drive is connected to the bottom plate of the rotating frame, the second blocking drive has an output end, and the output end of the second blocking drive is connected to the second blocking flap through a swing arm. The first and second blocking drive components 435 and 435 respectively drive the first and second blocking flaps 434 and 435 to rotate, opening or closing the push-out port of the rotating frame 432. When the first-stage pushing mechanism 42 pushes the flat tobacco stack into the flipping frame, the first and second blocking flaps 434 and 435, with the push-out port of the rotating frame 432 closed, can provide a limiting function for the tobacco stack. After the flipping process forms an upright tobacco stack, the push-out port of the rotating frame 432 opens, providing conditions for the release of the upright tobacco stack. At the same time, the first and second blocking flaps 434 and 435, with the push-out port of the rotating frame 432 open, can guide the pushing process of the tobacco stack.

[0126] In this embodiment, to maintain the stability of the conveying process, the cigarette packs output from the upstream packaging machine are generally placed flat (i.e., the wider side of the cigarette pack is at the bottom horizontal plane, and the narrower side is at the side vertical plane). The flat cigarette packs received are transported from the input end 31 to the lifting station 32 by the inlet belt conveyor. Subsequently, the automatic stacking mechanism 41 stacks the flat cigarette packs on the lifting station 32 layer by layer into the stacking station A1, and stacks them into the arrangement required for boxing, forming a flat cigarette stack. The stacked flat cigarette stack is pushed into the rotating frame 432 by the stack pushing mechanism. The cigarette stack flipping mechanism 43 flips the flat cigarette stack 90° to form an upright cigarette stack (i.e., the narrower side of the cigarette pack is at the bottom horizontal plane, and the wider side is at the side vertical plane) to meet the packaging requirements of the vertical boxing system. The upright cigarette stack can greatly reduce the area occupied at the bottom during the circulation process, which is beneficial to the spatial layout of the boxing system, reduces the area required for the boxing system, and forms a more compact production environment. The system automates the stacking and flipping of cigarette packs, ensuring uniform orientation and stable stack shape while reducing packaging damage and the risk of loose stacks.

[0127] Please refer to Figure 17-23 As shown, the cigarette stack feeding and folding forming device 5 of the vertical carton sealing machine in this embodiment includes a carton suction mechanism 51, a cigarette stack feeding mechanism 52, a carton bottom forming mechanism 53 and a carton top forming mechanism 54.

[0128] The box suction mechanism 51 is located between the box packing station A4 and the storage station A3. The box suction mechanism 51 is used to obtain the box blank in the carton warehouse 2, unfold the box blank into a vertical carton, and position the vertical carton to the box packing station A4.

[0129] The tobacco stack loading mechanism 52 is located between the stacking station A2 and the packing station A4. The tobacco stack loading mechanism 52 is used to push the upright tobacco stacks at the stacking station A2 into the upright cartons.

[0130] The bottom forming mechanism 53 of the carton is located at the bottom of the packing station A4, and the top forming mechanism 54 of the carton is located at the top of the packing station A4, for closing and forming the openings on both sides of the carton.

[0131] Specifically, the suction box mechanism 51 includes a box-pulling assembly 511 and an adsorption assembly 512. The box-pulling assembly 511 is used to drive the adsorption assembly 512 to move between the storage station A3 and the packing station A4. The box-pulling assembly 511 includes a box-pulling base plate 5111, a box-pulling slide plate 5112, a box-pulling drive component 5113, and a box-pulling transmission component 5114. The box-pulling slide plate 5112 is connected to the box-pulling base plate 5111 through a guide rail slider mechanism. The box-pulling drive component 5113 is linked to the box-pulling mounting plate through the box-pulling transmission component 5114. The box-pulling drive component 5113 is a servo motor, and the box-pulling transmission component 5114 is a ball screw and nut mechanism. The output shaft of the servo motor is connected to the ball screw and nut mechanism through a pulley mechanism, driving the box-pulling slide plate 5112 to move between the storage station A3 and the packing station A4.

[0132] The adsorption assembly 512 includes suction cup mounting plates 5121, two of which are vertically fixed to both ends of the movable plate of the trolley. Several vacuum suction cups 5122 are arranged on the side of the suction cup mounting plates 5121 facing the storage station A3. An air distribution channel is formed inside the suction cup mounting plates 5121. One end of the air distribution channel is connected to the vacuum suction cups 5122, and the other end is connected to a negative pressure device through an air pipe. The box blank is adsorbed or released by the multiple sets of vacuum suction cups 5122.

[0133] The carton bottom forming mechanism 53 of this embodiment includes a forming plate 531, which is disposed between the material storage station A3 and the carton packing station A4. The forming plate 531 has a supporting end 5311 and a forming end 5312 at its two ends. The forming end 5312 is disposed on one side of the material storage station A3 and has an arc-shaped guide surface. The arc-shaped guide surface is used to squeeze the carton blank to unfold it into a carton. The supporting end 5311 is disposed at the bottom of the carton packing station A4 and is used to support the unfolded carton.

[0134] In use, multiple sets of vacuum suction cups 5122 extend from both sides of the forming plate 531, adsorbing the upper side of the box blank; the box-pulling assembly 511 drives the adsorption assembly 512 to move from the storage station A3 to the packing station A4. The multiple sets of vacuum suction cups 5122 adsorb the box blank and drag it from the forming end 5312 of the forming plate 531 to the supporting end 5311. The lower side of the box blank is squeezed by the arc-shaped guide surface, changing from vertical to horizontal, so that the box blank unfolds into a carton; after the box-pulling assembly 511 drives the adsorption assembly 512 to the position, the unfolded carton is exactly in the packing station A4. In this way, the carton preparation is completed, waiting for the cigarette stacks to be put into the box.

[0135] The cigarette stack loading mechanism 52 of this embodiment includes a secondary stacking assembly 521. The secondary stacking assembly 521 includes a stacking mounting frame, a stacking drive component, a stacking upright plate, and a stacking plate. The top of the stacking upright plate is slidably connected to the stacking mounting frame via a slider guide mechanism, and the bottom of the stacking upright plate is connected to the stacking plate assembly. The stacking drive component is fixed to the stacking mounting frame and is a servo motor. The servo motor is connected to the stacking upright plate via a pulley assembly. The size of the stacking plate is adapted to the cigarette stack. The stacking drive component drives the stacking upright plate to move horizontally between the stacking station A2 and the packing station A4. The stacking plate pushes the cigarette stack supplied by the stacking station A2 into the carton on the packing station A4.

[0136] Furthermore, the tobacco stack loading mechanism 52 also includes a flared base plate 522, a first flared assembly 523, and a second flared assembly 524;

[0137] The first flaring component 523 and the second flaring component 524 are disposed at both ends of the flaring substrate 522, forming a packing channel 525 between them. The flaring substrate 522 is connected to the main frame 1 via a slider guide mechanism, allowing it to translate relative to the main frame 1, thereby moving the first flaring component 523 and the second flaring component 524 between the packing station A4 and the stacking station A2.

[0156] Please refer to Figure 24As shown, the lifting drive mechanism 6 of the vertical box-sealing machine in this embodiment includes a lifting frame 61, a lifting drive component 62, a lifting transmission component 63, and a lifting bracket 64. The lifting bracket 64 is vertically connected to the lifting frame 61 via a slider guide rail mechanism. The lifting frame 61 has a first support plate 641 and a second support plate 642. The first support plate 641 and the second support plate 642 are respectively used to support the bottom ends of the upright cigarette box, so as to drive the upright cigarette box to rise while avoiding interference with other components. The lifting drive component 62 is connected to the lifting frame 61 through the lifting transmission component 63. The lifting transmission component 63 is a sprocket mechanism, which drives the lifting frame 61 to translate between the packing station A4 and the lifting station A6 through the lifting drive component 62. Multiple proximity switches are arranged at various positions in the longitudinal direction of the lifting frame 61. They are responsible for controlling the operation of the lifting drive component 62, identifying the position of the first support plate 641 and the second support plate 642 at each station during the rising process, and the extreme positions of the vertical movement of the first support plate 641 and the second support plate 642.

[0157] Please refer to Figure 25-26 As shown, the electric sealing tape device 7 of the vertical carton sealing machine in this embodiment includes a carton head sealing mechanism 71 and a carton tail sealing mechanism 72; the carton head sealing mechanism 71 and the carton tail sealing mechanism 72 are respectively arranged on opposite sides of the sealing station A5; the carton head sealing mechanism is used to seal the carton head with tape, and the carton tail sealing mechanism is used to seal the carton tail with tape.

[0158] The box head sealing mechanism includes a tape supply assembly 711 and a sealing assembly 713. The tape supply assembly 711 includes a tape roller mounting plate 7111, a tape supply roller 7112, a tape conveying drive roller 7113, and a tape conveying drive component 7114. The tape roller mounting plate 7111 mainly serves as a support and connection, used to fix the box head sealing mechanism to the main frame 1. The end of the tape supply roller 7112 is rotatably connected to one side of the tape roller mounting plate 7111; the end of the tape conveying drive roller 7113 is rotatably connected to the tape roller mounting plate 7111, and the tape conveying drive component 7114 is drively connected to the tape conveying drive roller 7113. The tape conveying drive component 7114 is a geared motor, and the tape conveying drive component 7114 is fixed to the other side of the tape roller mounting plate 7111, with its output shaft connected to the tape conveying drive roller 7113.

[0159] In use, the sealing tape is wrapped around the glue supply roller 7112. The sealing tape is a type of sealing tape wound up. The sealing tape is wrapped around the glue delivery roller 7113 and extends to the sealing assembly 713. The sealing assembly 713 then seals the carton head with the tape, achieving automatic sealing. A glue delivery drive unit 7114 drives the glue delivery roller 7113 to rotate, providing power to the sealing tape in contact with it. This powers the sealing tape to the sealing assembly 713, which then attaches the sealing tape to the carton's hinge joint. Compared to the traditional method where the carton's movement pulls the sealing tape to generate power, by transmitting the power from the glue delivery drive unit 7114 to the sealing tape via the glue delivery roller 7113, the sealing tape is actively powered. This ensures smooth tape release, preventing uneven tension that could lead to poor adhesion or breakage, and significantly improving sealing efficiency.

[0160] Furthermore, the tape supply assembly 711 also includes a first guide roller 7115 and a second guide roller 7116, both of which are rotatably connected to the tape roller mounting plate 7111. The first guide roller 7115 and the second guide roller 7116 are respectively disposed on opposite sides of the active tape conveying roller 7113, and guide the sealing tape through the first guide roller 7115 and the second guide roller 7116, thereby increasing the contact area between the sealing tape and the surface of the active tape conveying roller 7113.

[0161] The surface of the active roller 7113 for conveying glue has a knurled surface, which is used to contact the sealing tape. The knurled surface can increase the friction between the active roller 7113 for conveying glue and the sealing tape.

[0162] By increasing the contact area and friction between the sealing tape and the surface of the conveying roller 7113, the power transmission efficiency of the conveying roller 7113 for the sealing tape is improved.

[0163] The tape supply assembly 711 in this embodiment further includes a tension roller 7117, a tensioning elastic element 7118, and a tensioning connecting plate 7119. The tensioning connecting plate 7119 is hinged to the tape roller mounting plate 7111. One end of the tensioning connecting plate 7119 is connected to the tape roller mounting plate 7111 via the tensioning elastic element 7118, and the other end is rotatably connected to the tension roller 7117. A first winding roller 7120 and a second winding roller 7121 are provided on both sides of the tension roller 7117. The sealing tape is sequentially wound around the first winding roller 7120, the tension roller 7117, and the second winding roller 7121 in the circumferential direction. The tensioning elastic element 7118 provides an elastic force that drives the tension roller 7117 away from the axis connecting the first winding roller 7120 and the second winding roller 7121, thereby adjusting the tension of the sealing tape during the conveying process and further ensuring the smooth release of the tape.

[0164] The tape roller mounting plate 7111 is provided with a tension sensor 7122 and a balance sensor 7123; the tension sensor 7122 is a proximity switch located near the tension roller 7117, and the position information of the tension roller 7117 is obtained through the proximity switch; the balance sensor 7123 is a diffuse reflection sensor located near the glue supply roller 7112, and the diffuse reflection sensor is used to obtain the balance information of the sealing film roll.

[0165] It also includes a tension control module and a low-load indicator module, both integrated into the main control system. The tension control module is signal-connected to the tension sensor 7122 and electrically connected to the tape conveying drive 7114. The tension control module controls the rotational speed of the tape conveying drive 7114 based on the feedback signal from the tension sensor 7122. The position of the tension roller 7117 is sensed by a proximity switch to determine the tension of the sealing tape, thereby accelerating or decelerating the rotation of the tape conveying drive 7114 to achieve flexible tape supply. The low-load indicator module is signal-connected to the low-load sensor 7123 and outputs a tape replacement alarm based on the feedback signal from the low-load sensor 7123. When the tape load is too low, the system triggers an alarm to prompt tape replacement.

One end of the width adjusting screw is screwed to the adjusting base plate through a ball nut, and the other end is connected to the width adjusting handwheel 7141. The width adjusting handwheel 7141 drives the adjusting base plate to slide on the adjusting frame, so that the adjusting base plate moves closer to or away from the sealing station A5, thereby adjusting the sealing width position.

[0171] A locking element is provided at the connection between the width adjusting screw and the adjusting frame. The locking element locks the relative position of the width adjusting screw and the adjusting frame by means of a shaft clamping mechanism.

[0172] The sealing substrate is connected to the adjustment substrate via several guide rods; a height adjustment handwheel 7142 and a height adjustment screw are provided between the sealing substrate and the adjustment substrate.

The top end of the pressure chamber adjusting screw is connected to the pressure chamber base plate via a screw support seat, and the bottom end of the pressure chamber adjusting screw is connected to the pressure chamber adjusting handwheel 7151. The pressure chamber base plate is driven to move closer to or further away from the adjusting base plate by the pressure chamber adjusting handwheel 7151, thereby adjusting the height position of the pressure chamber.

[0175] A locking element is provided at the connection between the pressure box adjusting screw and the pressure box head adjusting base plate. The locking element locks the relative position of the pressure box adjusting screw and the adjusting base plate by means of a shaft clamping mechanism.

[0176] The pressure plate is provided with a box sheet pressure bar, which is used to limit the box sheet on the side of the carton so that the box sheet on the side of the carton is tightly attached to the carton body;

[0177] A first roller assembly 717 is provided on the pressing base plate. The first roller assembly 717 includes a first roller seat, a first unpowered roller and a roller drive component. The roller drive component has a fixed end and a telescopic end. The fixed end of the roller drive component is connected to the pressing base plate, and the telescopic end of the roller drive component is connected to the first roller seat. A plurality of the first unpowered rollers are linearly arrayed on the first roller seat. The first unpowered rollers are used to limit the side panel connection of the carton so that the side panel connection of the carton is tightly attached to the carton body.

[0178] The sealing assembly 713 also includes a second roller assembly 716, which includes a roller adjusting frame, a roller seat fixing plate, a second roller seat, and a second unpowered roller.

The two are positioned opposite each other on both sides of the sealing station A5 to automatically seal the sides of the carton with tape. The specific shape and fixed position of the tape roller mounting plate 7111 of the tail sealing mechanism 72 and the head sealing mechanism 71 can be adjusted according to the overall layout and clearance requirements of the carton sealing machine. This will be understood by those skilled in the art and will not be elaborated here.

[0180] In this embodiment, the electric sealing tape device 7 is installed on both sides of the carton conveying channel of the carton sealing machine by mounting the carton head sealing mechanism 71 and the carton tail sealing mechanism 72. The carton head sealing mechanism 71 and the carton tail sealing mechanism 72 are respectively equipped with a tape supply component 711 and a sealing component 713. The tape is powered by a tape delivery drive component 7114 and the power is transmitted to the tape through the tape delivery drive roller 7113, thereby providing power to the sealing tape.

The flipping drive 431 drives the rotating frame 432 to switch to the upright position, so that the flat tobacco stack is flipped into an upright tobacco stack and the upright tobacco stack is positioned at the pushing station A2.

[0193] Packing and folding steps: The box suction mechanism 51 grabs the box blank in the carton warehouse 2, unfolds the box blank into an upright carton, and positions the upright carton at the packing station A4; the cigarette stack feeding mechanism 52 pushes the upright cigarette stack at the stacking station A2 into the upright carton; the bottom forming mechanism 53 and the top forming mechanism 54 fold the two sides of the carton to close, forming an upright cigarette box;

[0194] Lifting and sealing steps: The lifting drive mechanism 6 transports the upright cigarette box from the packing station A4 through the sealing station A5 to the lifting station A6. During the process of the upright cigarette box passing through the sealing station A5, the electric sealing tape device 7 seals the two sides of the upright cigarette box.

[0195] Pushing box procedure: The pushing box mechanism 9 pushes the upright smoke box from the lifting station A6 into the roller conveyor 8;

[0196] Emergency output procedure: The roller conveyor 8 sends the upright smoke box from the emergency outlet 81 into the emergency outlet lifting roller machine 11, and the emergency outlet lifting roller machine 11 lowers the upright smoke box to the manual handling height.

[0197] The turning process is as follows: Roller conveyor 8 transports the upright cigarette box through the turning station A7, and sliding turning mechanism 10 turns the upright cigarette box into a horizontal cigarette box at the turning station A7 for output.

[0198] Elevated conveying steps: Roller conveyor 8 directly feeds the horizontal smoke box into the elevated conveyor line from the downstream docking port 82, and then transports it to the preset position via the elevated conveyor line.

[0199] This embodiment of the vertical cigarette packing and sealing system adopts a different packaging method from the current mainstream, transforming the horizontal packaging method into a vertical one. This reduces the footprint of the packaging machine and allows for direct connection between the packaging machine and the packaging machine. It reforms the current environment where cigarette packs are transported remotely from the packaging area to the packaging area via an overhead conveyor line. The direct connection between the packaging machine and the packaging machine not only prevents scratches on the cigarette packs during long-distance transport but also avoids differences in appearance quality due to varying transport distances. Furthermore, converting the overhead conveyor system for cigarette packs to an overhead conveyor system for cigarette boxes reduces the overall material flow in the workshop. Secondly, the central control system controls the box-moving robot 13 to perform functions such as automatic feeding, automatic material calling, and automatic switching of cigarette box outlets, greatly freeing up workers, reducing their fatigue and workload, and improving the efficiency of the production process.

[0200] The improvements to the vertical cigarette packing and sealing system in this embodiment offer the following advantages:

[0201] Reduce labor intensity: The use of a system for loading blanks into boxes replaces manual processes, improving work efficiency, reducing labor input, and lowering the labor intensity of operators;

[0202] Small footprint: The system has a compact and innovative structural design with a vertical packaging box layout, which reduces the space occupied on the ground.

[0203] Reduced investment costs: simpler structure, lower investment, and easier maintenance;

[0204] Reduce logistics flow: Change the transportation of cigarettes from cartons to boxes, which significantly reduces logistics flow;

[0205] Improve production efficiency: Use automated equipment to replace manual operation and reduce the possibility of production stoppages and maintenance caused by failures in the overhead cigarette conveyor line.

[0206] It is important to emphasize that the aforementioned vertical cigarette packing and sealing system is a highly integrated automated system specifically designed for cigarette factories. It integrates multiple functions, including automatic box blank supply, automatic packing, automatic sealing, and automatic box conveying. It can automatically feed box blanks, automatically open, form, and seal cartons, and automatically stack and pack cigarettes. It can replace manual feeding in the packing and sealing process of tobacco factory packaging workshops, automatically completing tasks such as stacking and dismantling, material feeding, and recovery of incorrect box blanks. It is a highly efficient and integrated automated solution. Its application is not limited to cigarette factory production environments; it can also be widely used in other industries for automatic packing, sealing, feeding, and conveying. It provides a more efficient and convenient production environment, realizes a systematic process flow, and provides safety protection for equipment and operators, contributing to improved production efficiency and enhanced safety.
