Description

Technical Field

[0001] This invention relates to the field of cigarette packing equipment technology, and in particular to a control method and control system for a complete cigarette packing machine. Background Technology

[0002] In traditional cigarette production, after cigarettes are made and packaged, the cigarette cartons need to be packed into cardboard boxes for easy transport. Manual packing involves a series of operations, including unfolding the box, stacking the cigarette cartons, packing, and sealing. Manual packing is slow and prone to errors, resulting in incomplete packing. With the development of automated machinery, many cigarette manufacturers have begun using automated equipment for packing cigarettes. For automated cigarette carton packaging equipment, the cigarette cartons need to be stacked before being pushed into the cardboard box in one go. For example, Chinese patent application number 202410688174.5 discloses a cigarette pack stacking and conveying device. This device can only stack one row of cigarette cartons, resulting in low efficiency. In practice, according to the dropping method described in this application, the cigarette cartons are prone to tipping over during descent. For example, Chinese patent application number 202410625116.8 discloses an intelligent system for opening and forming packaging box blanks, including a control unit and an execution unit. The execution unit includes an execution mechanism, a movable suction cup group, and a fixed suction cup group. The control unit controls the execution mechanism to drive the movable suction cup group to adhere to the box body I, moving the box blank from the box blank storage station to the box blank forming station. The above-mentioned equipment can only complete one or part of the process individually, and cannot achieve the entire boxing operation automation with just one piece of equipment. However, when a cigarette packing machine is running, it needs to complete a series of operations such as unfolding the carton, stacking cigarette packs, packing, and sealing the carton. Therefore, it is necessary to design a whole-machine control method and control system for cigarette packing so that the cigarette packing machine can complete a series of actions for cigarette packing and achieve automated operation. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a control method and control system for an integrated cigarette packing machine, enabling the integrated cigarette packing machine to complete a series of actions in cigarette packing and achieve automated operation.

[0004] This invention is achieved through the following technical solution: This invention proposes a complete control system for cigarette packing machines, comprising: A cardboard box storage module, which is used to store cardboard boxes to be used; An unpacking module, which is used to remove cartons from the carton storage module and unfold the cartons; A stacking module, used to stack cigarette packs into multiple rows and multiple layers; The carton storage module is equipped with a carton retrieval block. The middle part of the carton retrieval block is rotatably installed at the lower part of the carton storage module. The lower end of the carton retrieval block is heavier than the upper end of the carton retrieval block. The upper end of the carton retrieval block blocks one side of the carton stored in the carton storage module. The carton storage module is equipped with a first photoelectric switch below the carton retrieval block. The unpacking module is equipped with a first telescopic rod, a second telescopic rod, a third telescopic rod, a fourth telescopic rod, a second photoelectric switch, a third photoelectric switch, and a fourth photoelectric switch. The first telescopic rod is used to control the pitch of the main swing arm, the second telescopic rod is used to control the position of the suction cup on the unpacking module, and the third and fourth telescopic rods are used to control the swing of the auxiliary swing arm on the unpacking module. The second and third photoelectric switches are fixed on the main swing arm, and the fourth photoelectric switch is fixed on the auxiliary swing arm. The second, third, and fourth photoelectric switches are all used to detect the swing position of the auxiliary swing arm. The stacking module is equipped with a fifth telescopic rod, a fifth photoelectric switch, a sixth photoelectric switch, and a seventh photoelectric switch. The fifth telescopic rod is used to drive the second conveyor belt to move laterally. The fifth photoelectric switch is installed on both sides of the first conveyor belt, and the sixth and seventh photoelectric switches are installed on both sides of the second conveyor belt. The fifth, sixth, and seventh photoelectric switches are used to sense the position of the cigarette stick.

[0005] Furthermore, the control system also includes: A cigarette pushing module, which is used to push the stacked cigarette packs into an unfolded cardboard box; A sealing module, which is used to fold the large and small sides of the carton containing cigarette packs; A box-pushing module, which is used to push away a cardboard box with its large and small sides folded. Tape reel module, the tape reel module being used to apply tape to cardboard boxes; The cigarette pushing module includes a drive motor and an eighth photoelectric switch. The drive motor is used to drive the push plate to move, and the eighth photoelectric switch is used to detect the sliding position of the drive motor. The sealing module includes a sixth telescopic rod, a seventh telescopic rod, and a ninth photoelectric switch. A first folding edge assembly is slidably installed on the sealing module. The sealing module also has a second folding edge assembly. The sixth telescopic rod is used to drive the first folding edge assembly to slide, and the seventh telescopic rod is used to drive the second folding edge assembly. The ninth photoelectric switch is fixed on both sides of the sealing module and is used to sense the sliding position of the first folding edge assembly. The push box module includes a first electric slide rail and a tenth photoelectric switch. The first electric slide rail is used to drive the linkage mechanism on the push box module to move, and the tenth photoelectric switch is used to control the sliding position of the linkage mechanism. Both ends of the first electric slide rail are equipped with travel sensing switches.

[0006] Furthermore, a flaring module is provided between the cigarette pushing module and the box opening module. The flaring module includes a stationary component and a sliding component. An eighth telescopic rod is provided between the stationary component and the sliding component. The eighth telescopic rod is used to push the sliding component to slide on the stationary component.

[0007] Furthermore, a second electric slide rail is provided on one side of the stacking module, a first lifting platform is provided on the second electric slide rail, and an eleventh photoelectric switch is provided on the second electric slide rail. The eleventh photoelectric switch is used to detect the descent height of the first lifting platform. The stacking module is also provided with a tenth telescopic rod and a second lifting platform. The second lifting platform is installed on the stacking module through an inclined guide rail, and the telescopic end of the tenth telescopic rod is connected to the second lifting platform.

[0008] Furthermore, a method for controlling a cigarette packing machine, applied to the cigarette packing machine control system according to any one of claims 1 to 4, includes the following steps: Step S1: The cigarette sticks enter the second conveyor belt through the first conveyor belt. The cigarette sticks are arranged in a row on the second conveyor belt. When the cigarette sticks block the third photoelectric switch, both the first and second conveyor belts stop running, the tenth telescopic rod retracts, the second lifting platform rises, and then the fifth telescopic rod extends, which widens the gap between the second conveyor belts and causes the cigarette sticks to fall onto the upper part of the first lifting platform. Step S2: The cigarette bar falls, the second electric slide rail drives the first lifting platform to descend, and then the fifth telescopic rod retracts, causing the second conveyor belt to reset. Step S3: When the first lifting platform descends to the eleventh photoelectric switch detection position, both the first and second conveyor belts stop running. At the same time, the eighth telescopic rod extends, causing the sliding component of the flaring module to unfold and extend into the carton. After the first lifting platform descends to the cigarette pushing position, the stacked cigarette strips are pushed into the unfolded carton through the cigarette pushing module. Step S4: The sixth and seventh telescopic rods extend, folding the large and small sides of the carton through the first and second folding components; Step S5: Move the linkage mechanism via the first electric slide rail, and move the carton via the linkage mechanism; Step S6: Under the action of the push box module, the carton passes between the tape reel modules, and tape is applied to both sides of the carton through the tape reel modules.

[0009] Furthermore, in step S2, the first lifting platform descends to a height equal to the height of the cigarette bar each time, and when the second conveyor belt resets, the second conveyor belt clamps the uppermost cigarette bar through the clamping plate on the inner side of the second conveyor belt.

[0010] Furthermore, while step S1 is being performed, the first telescopic rod retracts, causing the main swing arm on the unpacking module to rise. After the main swing arm sucks up the cardboard box in the cardboard box storage module through the suction cup, the first telescopic rod extends to remove the cardboard box from the cardboard box storage module. During the removal process, the box removal stop is moved. After the first photoelectric switch senses that the lower end of the box removal stop has moved away, the cardboard box storage module drives the remaining cardboard boxes to move forward.

[0011] Furthermore, after the main swing arm removes the cardboard box, the second telescopic rod extends to adjust the position of the cardboard box so that it is aligned with the cigarette pack. At the same time, the third telescopic rod extends and the fourth telescopic rod retracts. After the auxiliary swing arm rotates 180°, the suction cup on the auxiliary swing arm adheres to the cardboard box. When the third photoelectric switch senses that the auxiliary swing arm is close, the third telescopic rod stops extending and the air in the suction cup is extracted through the negative pressure tube. Then the third telescopic rod retracts, causing the cardboard box to unfold.

[0012] Furthermore, when the unpacking module takes out and opens the box, the eighth telescopic rod is in a retracted state and the flaring module is in a folded state. Before pushing the cigarette in step S3, the eighth telescopic rod extends, so that the flaring module unfolds and the sliding component extends into the carton.

[0013] Furthermore, in step S4, the seventh telescopic rod first drives the second folding assembly to fold the small side of one side of the carton, then the sixth telescopic rod extends, and after folding the small side of the other side of the carton through the first folding assembly, the large side of the carton is folded.

[0014] The beneficial effects of this invention are: by coordinating various photoelectric switches and telescopic rods on the equipment, the entire cigarette packing machine can operate efficiently. Only one machine is needed to complete a series of operations such as stacking cigarette packs, taking boxes, opening boxes, packing boxes, and sealing boxes, which greatly reduces the space occupied by the equipment and facilitates the layout of the equipment.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0018] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0019] like Figures 1 to 18As shown, an embodiment of the present invention provides a complete control system for cigarette packing machines, including: a carton storage module 1 for storing cartons to be used; an opening module 2 for removing cartons from the carton storage module 1 and unfolding the cartons; and a stacking module 3 for stacking cigarette packs into multiple rows and layers; wherein, the carton storage module 1 is provided with a carton-removing stop 101, the middle of which is rotatably installed at the lower part of the carton storage module 1, and the lower end of the carton-removing stop 101 is weight-bearing. The upper part of the box-retrieving block 101 is heavier than the upper part of the box-retrieving block 101. The upper part of the box-retrieving block 101 blocks one side of the cardboard box stored in the cardboard box storage module 1. The cardboard box storage module 1 is equipped with a first photoelectric switch 102 below the box-retrieving block 101. The box-opening module 2 is equipped with a first telescopic rod 201, a second telescopic rod 202, a third telescopic rod 203, a fourth telescopic rod 204, a second photoelectric switch 205, a third photoelectric switch 206, and a fourth photoelectric switch 207. The first telescopic rod 201 is used to control the pitch of the main swing arm 208. Telescopic rod 202 is used to control the position of the suction cup on the unpacking module 2. The third telescopic rod 203 and the fourth telescopic rod 204 are used to control the swing of the auxiliary swing arm 209 on the unpacking module 2. The second photoelectric switch 205 and the third photoelectric switch 206 are fixed on the main swing arm 208, and the fourth photoelectric switch 207 is fixed on the auxiliary swing arm 209. The second photoelectric switch 205, the third photoelectric switch 206, and the fourth photoelectric switch 207 are all used to detect the swing position of the auxiliary swing arm 209. The stacking module 3 is provided with a fifth telescopic rod 301, a fifth photoelectric switch 302, a sixth photoelectric switch 303, and a seventh photoelectric switch 304. The fifth telescopic rod 301 is used to drive the second conveyor belt 306 to move laterally. The fifth photoelectric switch 302 is installed on both sides of the first conveyor belt 305, and the sixth photoelectric switch 303 and the seventh photoelectric switch 304 are installed on both sides of the second conveyor belt 306. The fifth photoelectric switch 302, the sixth photoelectric switch 303, and the seventh photoelectric switch 304 are used to sense the position of the cigarette strip.

[0020] When the unpacking module 2 removes a carton from the carton storage module 1, it will move the carton retrieval block 101, causing the first photoelectric switch 102 to sense the movement of the carton retrieval block 101. The controller's count will increment by 1, and at the same time, the remaining cartons on the carton storage module 1 will be moved forward via a belt or chain, ready for the unpacking module 2 to retrieve them next time.

[0021] like Figures 7 to 11As shown, the stacking module 3 includes: a fifth telescopic rod 301, a fifth photoelectric switch 302, a sixth photoelectric switch 303, a seventh photoelectric switch 304, a first conveyor belt 305, a second conveyor belt 306, a first lifting platform 308, and a stop bar. The first conveyor belt 305, the second conveyor belt 306, and the first lifting platform 308 are all mounted on the frame, with one end of the first conveyor belt 305 connected to one end of the second conveyor belt 306. The first lifting platform 308 is located below the second conveyor belt 306, and the stop bar has two ends... The cigarette stick is vertically installed between the second conveyor belts 306. A transverse movement mechanism is provided on both sides of the second conveyor belts 306. The transverse movement mechanism is powered by a fifth telescopic rod 301. When the fifth telescopic rod 301 extends, it drives the second conveyor belts 306 to move outwards through the transverse movement mechanism, increasing the spacing between the second conveyor belts 306, allowing the cigarette stick to fall onto the first lifting platform 308. When the cigarette stick moves from the first conveyor belt 305 to the second conveyor belt 306, it will stop on the second conveyor belt 306 due to the obstruction of the stop bar. Under the thrust of the second conveyor belt 306, the cigarette sticks are brought close together. When the cigarette sticks move to the position of the sixth photoelectric switch 303 or the seventh photoelectric switch 304, they will block the light of the photoelectric switch, allowing the photoelectric switch to sense the position of the cigarette sticks. When the seventh photoelectric switch 304 is blocked, it indicates that the cigarette sticks have accumulated to a suitable quantity. At this time, both the first conveyor belt 305 and the second conveyor belt 306 stop moving. Then, the tenth telescopic rod 309 retracts, raising the second lifting platform 310 and lifting the excess cigarette sticks on the second conveyor belt 306. Subsequently, the fifth telescopic rod 301 increases the distance between the second conveyor belts 306 through the lateral movement mechanism, causing the cigarette sticks to fall onto the first lifting platform 308. After falling, the fifth telescopic rod 301 retracts, resetting the second conveyor belt 306. When the second conveyor belt 306 resets, the clamps at the bottom of the second conveyor belt 306 level the fallen cigarette sticks, making the cigarette sticks neatly stacked. After the cigarette sticks fall, the first lifting platform 308 descends a certain distance to await the fall of the next layer of cigarette sticks.

[0022] like Figures 3 to 6As shown, the unpacking module 2 includes: a first telescopic rod 201, a second telescopic rod 202, a third telescopic rod 203, a fourth telescopic rod 204, a second photoelectric switch 205, a third photoelectric switch 206, a fourth photoelectric switch 207, a main swing arm 208, and a secondary swing arm 209. The pitch of the main swing arm 208 is controlled by the first telescopic rod 201. The main swing arm 208 is equipped with a sliding connecting plate, the position of which is controlled by the second telescopic rod 202. A side plate is installed on the connecting plate, forming a "U"-shaped structure with the side plate. The secondary swing arm 209 can swing within the "U"-shaped structure. The swing of the auxiliary swing arm 209 is controlled by the third telescopic rod 203 and the fourth telescopic rod 204. If we take the angle when the auxiliary swing arm 209 picks up the carton as 0°, when the auxiliary swing arm 209 is at 0°, the third photoelectric switch 206 is blocked; when the auxiliary swing arm 209 is at 90°, the fourth photoelectric switch 207 is blocked; and when the auxiliary swing arm 209 is at 180°, the second photoelectric switch 205 is blocked. The controller can detect the swing position of the auxiliary swing arm 209 through the second photoelectric switch 205, the third photoelectric switch 206, and the fourth photoelectric switch 207, and thus make corresponding actions. When the unpacking module 2 retrieves a cardboard box, the position of the suction cup on the connecting plate can be controlled by the second telescopic rod 202 to adapt to cardboard boxes of different sizes. At the same time, the controller controls the auxiliary swing arm 209 to rotate to a position of 180° to prevent the auxiliary swing arm 209 from hitting the cardboard box storage module 1 when retrieving the cardboard box. After the cardboard box retrieval action is completed, the auxiliary swing arm 209 rotates to 0°. After the suction cup on the auxiliary swing arm 209 picks up the cardboard box, it rotates to 90° to complete the cardboard box unfolding operation. After unfolding the cardboard box, the position of the connecting plate can be controlled again by the second telescopic rod 202 to adjust the position of the cardboard box so that the unfolded cardboard box can be aligned with the position where the cigarette packs are stacked, making it easier to push the cigarette packs in.

[0023] In a preferred embodiment, such as Figure 12As shown, the control system also includes: a cigarette pushing module 4, used to push the stacked cigarettes into the unfolded cardboard box; a box sealing module 5, used to fold the large and small sides of the cardboard box containing the cigarettes; a box pushing module 6, used to push the cardboard box with the folded large and small sides away; and a tape reel module 7, used to attach tape to the cardboard box; wherein, the cigarette pushing module 4 includes a drive motor 401 and an eighth photoelectric switch 402, the drive motor 401 is used to drive the push plate to move, and the eighth photoelectric switch 402 is used to detect the sliding position of the drive motor 401; the box sealing module 5 includes a sixth telescopic rod 501, a seventh telescopic rod 502, and a ninth photoelectric switch 503, the box sealing module 5... The first folding component 504 is slidably mounted on the top. The sealing module 5 is also provided with a second folding component 505. The sixth telescopic rod 501 is used to drive the first folding component 504 to slide. The seventh telescopic rod 502 is used to drive the second folding component 505. The ninth photoelectric switch 503 is fixed on both sides of the sealing module 5. The ninth photoelectric switch 503 is used to sense the sliding position of the first folding component 504. The pushing module 6 includes a first electric slide rail 601 and a tenth photoelectric switch 602. The first electric slide rail 601 is used to drive the linkage mechanism on the pushing module 6 to move. The tenth photoelectric switch 602 is used to sense the sliding position of the linkage mechanism. The first electric slide rail 601 is provided with a travel sensing switch 603 at both ends.

[0024] After the cigarette sticks are stacked and the carton is unfolded, the controller controls the drive motor 401 to run, so that the cigarette pushing module 4 has the power to move. The pusher pushes the stacked cigarette sticks into the carton. After the cigarette pushing action is completed, the drive motor 401 controls the pusher to reset. The eighth photoelectric switch 402 is even in the reset position to detect whether the pusher has reset, so as to prevent the first lifting platform 308 from rising if the pusher has not reset, which would cause damage to the equipment.

[0025] like Figure 13 , Figure 14 As shown, after the cigarette packs are packed, the large and small edges of the carton opening need to be folded and taped. The sealing module 5 includes a sixth telescopic rod 501, a seventh telescopic rod 502, a ninth photoelectric switch 503, a first folding edge assembly 504, and a second folding edge assembly 505. The carton needs to have its small edges folded first, followed by the large edges. During sealing, the controller first extends the seventh telescopic rod 502, causing the second folding edge assembly 505 to rotate and fold one side of the small edge. Then, the controller extends the sixth telescopic rod 501, causing the first folding edge assembly 504 to move. As the first folding edge assembly 504 moves, it folds the other side of the small edge. Finally, the first folding edge assembly 504 folds the large edge, completing the sealing. After sealing, the carton is pushed into the tape reel module 7 via the pusher module 6, and sealing tape is applied to both sides of the carton via the tape reel module 7.

[0026] In a specific embodiment, such as Figure 17 , Figure 18 As shown, a flaring module 8 is provided between the cigarette pushing module 4 and the box opening module 2. The flaring module 8 includes a stationary component 801 and a sliding component 802. An eighth telescopic rod 803 is provided between the stationary component 801 and the sliding component 802. The eighth telescopic rod 803 is used to push the sliding component 802 to slide on the stationary component 801. A connecting rod is provided between the sliding component 802 and the stationary component 801. When the eighth telescopic rod 803 extends, the sliding component 802 is pushed away from the stationary component 801. The guide plate on the sliding component 802 can be unfolded and extended into the carton through the connecting rod mechanism, thereby guiding the cigarettes smoothly into the carton. After the action of pushing the cigarettes into the carton is completed, the eighth telescopic rod 803 retracts, and the sliding component 802 moves towards the stationary component 801. The guide plate on the sliding component 802 can be folded through the connecting rod mechanism to facilitate the actions of pushing the carton and unfolding the carton.

[0027] Specifically, a second electric slide rail 307 is provided on one side of the stacking module 3, and a first lifting platform 308 is provided on the second electric slide rail 307. An eleventh photoelectric switch 311 is provided on the second electric slide rail 307. The eleventh photoelectric switch 311 is used to detect the descent height of the first lifting platform 308. The second electric slide rail 307 controls the first lifting platform 308 to descend accurately by the corresponding distance, so that the cigarette sticks can be stacked in multiple layers on the first lifting platform 308. At the same time, the distance between the top layer of cigarette sticks and the second conveyor belt 306 is controlled to be 3-10cm to reduce the falling distance of the cigarette sticks and prevent the cigarette sticks from becoming loose when falling. The stacking module 3 is also equipped with a tenth telescopic rod 309 and a second lifting platform 310. The second lifting platform 310 is installed on the stacking module 3 via an inclined guide rail. The telescopic end of the tenth telescopic rod 309 is connected to the second lifting platform 310. When the second lifting platform 310 moves laterally, it can support the excess cigarette sticks under the second lifting platform 310, preventing the excess cigarette sticks from falling when the second lifting platform 310 moves laterally, so that the number of cigarette sticks in each layer is the same when the cigarette sticks are stacked.

[0028] In a preferred embodiment, it is applied to the tobacco packing machine control system of any one of claims 1 to 4, comprising the following steps: Step S1: The cigarette sticks enter the second conveyor belt via the first conveyor belt, arranging themselves in a row. When a cigarette stick blocks the third photoelectric switch, both the first and second conveyor belts stop operating, the tenth telescopic rod 309 retracts, and the second lifting platform 310 rises. Subsequently, the fifth telescopic rod 301 extends, widening the gap between the second conveyor belts and causing the cigarette sticks to fall onto the upper part of the first lifting platform 308. When the cigarette sticks move from the first conveyor belt 305 to the second conveyor belt 306, they will stop on the second conveyor belt 306 due to the obstruction of the stop bar, and the pushing force of the second conveyor belt 306 will cause the cigarette sticks to come close together. When the cigarette stick moves to the position of the sixth photoelectric switch 303 or the seventh photoelectric switch 304, it will block the light of the photoelectric switch, causing the photoelectric switch to sense the position of the cigarette stick. When the seventh photoelectric switch 304 is blocked, it means that the cigarette stick has accumulated to a suitable amount. At this time, the first conveyor belt 305 and the second conveyor belt 306 both stop moving. Then the tenth telescopic rod 309 retracts, causing the second lifting platform 310 to rise, so that the excess cigarette stick on the second conveyor belt 306 is lifted. Then the fifth telescopic rod 301 increases the distance between the second conveyor belts 306 through the lateral movement mechanism, causing the cigarette stick to fall onto the first lifting platform 308.

[0029] Step S2: The cigarette bar falls, the second electric slide rail 307 drives the first lifting platform 308 to descend, and then the fifth telescopic rod 301 retracts, so that the second conveyor belt is reset to await the fall of the next layer of cigarette bars.

[0030] Step S3: When the first lifting platform 308 descends to the detection position of the eleventh photoelectric switch 311, both the first and second conveyor belts stop running. At the same time, the eighth telescopic rod 803 extends, causing the sliding component 802 of the flaring module 8 to unfold and extend into the carton. After the first lifting platform 308 descends to the cigarette pushing position, the stacked cigarette sticks are pushed into the unfolded carton through the cigarette pushing module 4. The cigarette sticks are guided smoothly into the carton through the flaring module 8.

[0031] In step S4, the sixth telescopic rod 501 and the seventh telescopic rod 502 extend, folding the large and small sides of the carton through the first folding assembly 504 and the second folding assembly 505. The sealing module 5 includes the sixth telescopic rod 501, the seventh telescopic rod 502, the ninth photoelectric switch 503, the first folding assembly 504, and the second folding assembly 505. The carton needs to have its small side folded first, and then its large side folded. When sealing the carton, the controller first controls the seventh telescopic rod 502 to extend, causing the second folding assembly 505 to rotate and fold the small side on one side. Then, the controller controls the sixth telescopic rod 501 to extend, causing the first folding assembly 504 to move. When the first folding assembly 504 moves, it folds the small side on the other side. Then, the first folding assembly 504 folds the large side, completing the sealing process.

[0032] Step S5: The first electric slide rail 601 drives the linkage mechanism to move, and the linkage mechanism drives the carton to move, so that the carton enters the next station. Step S6: Under the action of the push box module 6, the carton passes between the tape reel module 7. Tape is applied to both sides of the carton by the tape reel module 7. After sealing, the carton is pushed into the tape reel module 7 by the push box module 6. Sealing tape is then applied to both sides of the carton by the tape reel module 7.

[0033] In a preferred embodiment, in step S2, the first lifting platform 308 descends to a height equal to the height of the cigarette sticks each time, thereby maintaining the falling height of the cigarette sticks and preventing the cigarette sticks from becoming loose during the falling process due to excessive falling height. When the second conveyor belt resets, the second conveyor belt clamps the top layer of cigarette sticks through the clamping plate on the inner side of the second conveyor belt, thereby making the top layer of cigarette sticks neatly stacked.

[0034] Preferably, while step S1 is being performed, the first telescopic rod 201 retracts, causing the main swing arm 208 on the box opening module 2 to rise. After the main swing arm 208 sucks up the carton in the carton storage module 1 through the suction cup, the first telescopic rod 201 extends to remove the carton from the carton storage module 1. During the removal process, the box removal stop 101 is moved. After the first photoelectric switch 102 senses that the lower end of the box removal stop 101 has moved away, the carton storage module 1 drives the remaining carton to move forward.

[0035] Specifically, after the main swing arm 208 removes the cardboard box, the second telescopic rod 202 extends to adjust the position of the cardboard box so that it is aligned with the cigarette pack. At the same time, the third telescopic rod 203 extends and the fourth telescopic rod 204 retracts. After the auxiliary swing arm 209 rotates 180°, the suction cup on the auxiliary swing arm 209 adheres to the cardboard box. When the third photoelectric switch 206 senses that the auxiliary swing arm 209 is close, the third telescopic rod 203 stops extending and draws air from the suction cup through the negative pressure tube. Then the third telescopic rod 203 retracts, causing the cardboard box to unfold.

[0036] The pitch of the main swing arm 208 is controlled by the first telescopic rod 201. The main swing arm 208 is equipped with a sliding connecting plate, the position of which is controlled by the second telescopic rod 202. A side plate is installed on the connecting plate, forming a "U"-shaped structure with the connecting plate. The secondary swing arm 209 can swing 180° within the "U"-shaped structure. The swing of the secondary swing arm 209 is controlled by the third telescopic rod 203 and the fourth telescopic rod 204. If we take the angle when the secondary swing arm 209 picks up the carton as 0°, when the secondary swing arm 209 is at 0°, the third photoelectric switch 206 is blocked; when the secondary swing arm 209 is at 90°, the fourth photoelectric switch 207 is blocked; and when the secondary swing arm 209 is at 180°, the second photoelectric switch 205 is blocked. The controller can detect the swing position of the secondary swing arm 209 through the second photoelectric switch 205, the third photoelectric switch 206, and the fourth photoelectric switch 207, and thus make corresponding actions. When the unpacking module 2 retrieves a cardboard box, the position of the suction cup on the connecting plate can be controlled by the second telescopic rod 202 to adapt to cardboard boxes of different sizes. At the same time, the controller controls the auxiliary swing arm 209 to rotate to a position of 180° to prevent the auxiliary swing arm 209 from hitting the cardboard box storage module 1 when retrieving the cardboard box. After the cardboard box retrieval action is completed, the auxiliary swing arm 209 rotates to 0°. After the suction cup on the auxiliary swing arm 209 picks up the cardboard box, it rotates to 90° to complete the cardboard box unfolding operation. After unfolding the cardboard box, the position of the connecting plate can be controlled again by the second telescopic rod 202 to adjust the position of the cardboard box so that the unfolded cardboard box can be aligned with the position where the cigarette packs are stacked, making it easier to push the cigarette packs in.

[0037] In a specific embodiment, when the unpacking module 2 is taking out and opening the box, the eighth telescopic rod 803 is in a retracted state and the flaring module 8 is in a folded state. Before pushing the cigarette in step S3, the eighth telescopic rod 803 extends, so that the flaring module 8 unfolds and the sliding component 802 extends into the carton. The flaring module 8 includes a stationary component 801 and a sliding component 802. The eighth telescopic rod 803 is provided between the stationary component 801 and the sliding component 802. The eighth telescopic rod 803 is used to push the sliding component 802 to slide on the stationary component 801. A connecting rod is provided between the sliding component 802 and the stationary component 801. When the eighth telescopic rod 803 extends, the sliding component 802 is pushed away from the stationary component 801. The guide plate on the sliding component 802 can be unfolded and extended into the carton through the connecting rod mechanism, thereby guiding the cigarette sticks smoothly into the carton. After the action of pushing the cigarettes into the carton is completed, the eighth telescopic rod 803 retracts, and the sliding component 802 moves towards the stationary component 801. The guide plate on the sliding component 802 can be folded through the connecting rod mechanism to facilitate the actions of pushing the carton and unfolding the carton.

[0038] Specifically, in step S4, the seventh telescopic rod 502 first drives the second folding assembly 505 to fold the small side of one side of the carton, and then the sixth telescopic rod 501 extends and folds the small side of the other side of the carton through the first folding assembly 504, and then folds the large side of the carton, so that the large and small sides of the carton are folded smoothly.

[0039] Of course, the present invention may have many other embodiments. Based on this embodiment, other embodiments obtained by those skilled in the art without any creative effort are all within the scope of protection of the present invention.
