Abstract

This invention discloses an automatic cigarette pack palletizing device, relating to the field of palletizing technology. The invention features a pack-sorting mechanism located behind the palletizing mechanism, allowing multiple cigarette packs to be organized during transport and then gripped by the palletizing mechanism. This simultaneous palletizing of multiple packs effectively improves the efficiency of automatic cigarette pack palletizing. Furthermore, by placing an electric conveyor belt on the end walls of clamping plates one and two, the electric conveyor belt provides upward transport power to the cigarette packs, preventing them from falling off during palletizing.

Description

Technical Field

[0001] This invention relates to the field of palletizing technology, and more particularly to an automatic palletizing device for cigarette packs. Background Technology

[0002] In the existing technology, cigarette packs are usually transferred by conveying equipment before palletizing. Due to factors such as vibration, friction and differences in the shape of the cigarette packs themselves during the conveying process, the cigarette packs are often in a scattered state when they are conveyed to the palletizing station, making it difficult to form a regular arrangement.

[0003] To address the scattered nature of cigarette packs, existing palletizing equipment typically employs a single-pack-at-a-time operation mode. This involves picking up, shifting, and placing the packs one by one to complete the palletizing process. While this mode can handle the scattered nature of the packs, processing only one pack at a time results in a long palletizing cycle and low overall efficiency. This makes it difficult to meet the demands of high-speed palletizing for large-scale production. Furthermore, during the palletizing process, the smooth plastic film covering the packs can easily cause them to slip, affecting not only the stability and neatness of the palletizing but also potentially damaging the packs, increasing production costs and quality risks. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of low efficiency in grabbing and stacking cigarette packs during the existing technology, and the easy slippage of cigarette packs during the grabbing process, and to propose an automatic cigarette pack stacking device.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0010] Preferably, the bottom of the clamping plate two is slidably connected to a support plate that is parallel to the top plate, and a pneumatic push rod two that is perpendicular to it is fixedly installed on the clamping plate two, and the telescopic end of the pneumatic push rod two is fixedly connected to the support plate.

[0011] Preferably, the packaging mechanism includes a frame fixedly installed on the workshop floor, and a horizontally arranged electric conveyor platform 1 is installed inside the frame. The right end of the electric conveyor platform 1 extends to the outside of the frame. An electric conveyor platform 2 is installed inside the frame, parallel to the lower left end of the electric conveyor platform 1. A temporary storage platform is fixedly installed inside the frame, located directly in front of the electric conveyor platform 2. The top of the temporary storage platform is flush with the top of the conveyor belt inside the electric conveyor platform 2. The front end of the temporary storage platform extends to the outside of the frame and is correspondingly arranged with the palletizing mechanism. A baffle is provided on the electric conveyor platform 2. An electric slide rail 1 is fixedly installed inside the frame, arranged longitudinally above the electric conveyor platform 2 and the temporary storage platform. A push plate is connected to the sliding end of the electric slide rail 1, located on the top of the electric conveyor platform 2 and the temporary storage platform.

[0012] Preferably, a downwardly inclined pneumatic push rod three is fixedly installed on the sliding end of the electric slide rail one, and a push plate is fixedly installed on the telescopic end of the pneumatic push rod three.

[0013] Preferably, the conveyor belt and temporary storage platform inside the electric conveyor platform 2 are provided with evenly distributed air holes, and air boxes located below the air holes are installed inside both the electric conveyor platform 2 and the temporary storage platform.

[0014] Preferably, the baffle is slidably installed on the electric conveyor platform 2, and an electric slide rail 2 is fixedly installed in the frame and arranged parallel to the electric conveyor platform 2 below it. The sliding end of the electric slide rail 2 is fixedly connected to the baffle. A slide table located between the electric conveyor platform 1 and the electric conveyor platform 2 is slidably installed in the frame. A pneumatic push rod 4 is fixedly installed in the frame and arranged parallel to the electric conveyor platform 1 below it. The telescopic end of the pneumatic push rod 4 is fixedly connected to the slide table.

[0015] Preferably, a roller is rotatably mounted inside the frame between the electric conveyor table and the slide table, and the roller is located below the left end of the electric conveyor table. The outer surface of the roller is covered with an adhesive layer, and a horizontally arranged electric conveyor belt is mounted on the top of the slide table.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, by providing a packing mechanism behind the palletizing mechanism, multiple cigarette packs can be sorted by the packing mechanism during the conveying process, and then grabbed by the gripping mechanism in the palletizing mechanism. The multiple cigarette packs are then palletized simultaneously, which can effectively improve the efficiency of automatic cigarette pack palletizing. At the same time, by setting the electric conveyor belt one on the end walls of clamping plate one and clamping plate two, the electric conveyor belt one can provide upward conveying power to the cigarette packs, which helps to prevent the cigarette packs from falling off during the palletizing process after being grabbed. With the top plate stopping the cigarette packs, multiple cigarette packs can be aligned at the same height for more precise drop and release, which effectively improves the stability and accuracy of the device during the palletizing process.

[0018] 2. In this invention, by attaching an adhesive layer to the surface of the inner conveyor belt of the electric conveyor belt, the stability of the cigarette pack being held between the clamping plates can be further improved by the weak adhesion between the adhesive layer and the surface of the cigarette pack. At the same time, during the release of the cigarette pack, the separation of the adhesive layer on the surface of the inner conveyor belt of the electric conveyor belt from the surface of the cigarette pack can remove the dust and impurities attached to the surface of the cigarette pack, thereby achieving the cleaning operation of the front and rear end walls of the cigarette pack during the stacking process, which helps to ensure the cleanliness of the cigarette pack during the stacking process.

[0019] 3. In this invention, the push plate is connected to the sliding end of the electric slide rail by the pneumatic push rod three. With the extension and retraction adjustment of the pneumatic push rod three, the position of the push plate can be moved up and down. This avoids the push plate from interfering with the cigarette packs on the electric conveyor table two during the reset process. This ensures that the arrangement of the cigarette packs on the electric conveyor table two is not affected by the push plate, and continuous arrangement of the cigarette packs is achieved. At the same time, the up and down movement of the push plate is coordinated with its forward and backward movement controlled by the electric slide rail one. A temporary storage platform is set up to temporarily store the arranged cigarette packs. This allows the feeding of cigarette packs at the front of the temporary storage platform to be coordinated with the gripping mechanism, which greatly reduces the waiting time of the gripping mechanism and helps to improve the stacking efficiency of the device.

[0020] 4. In this invention, by sliding the slide table between the first electric conveyor table and the second electric conveyor table, and cooperating with the rotation of the roller set on the left end of the first electric conveyor table above the slide table, the posture of the cigarette pack can be flipped and adjusted on the slide table. At the same time, by attaching the adhesive layer to the surface of the roller, not only can the stability of the cigarette pack flipping driven by the rotation of the roller be improved, but also the dust and impurities adhering to the side wall of the cigarette pack can be cleaned during the flipping process, which is conducive to further ensuring the cleanliness of the cigarette pack sorting and stacking process.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] Example: This example provides an automatic cigarette pack palletizing device, see [link / reference]. Figure 1 - Figure 12 Specifically, the palletizing mechanism includes a base 1 fixedly installed on the workshop floor, an electric rotary table 11 rotatably mounted on the base 1, a vertically arranged electric lifting rail 12 fixedly mounted on the top of the electric rotary table 11, a multi-axis robotic arm 13 fixedly mounted on the sliding end of the electric lifting rail 12, a gripping mechanism 14 mounted at the end of the multi-axis robotic arm 13, and a top plate 141, a clamping plate 142 perpendicularly arranged on one side of the bottom of the top plate 141, a clamping plate 143 parallel to the clamping plate 142 slidably connected to the other side of the bottom of the top plate 141, a pneumatic push rod 144 perpendicularly arranged on the top plate 141, and the telescopic end of the pneumatic push rod 144 fixedly connected to the clamping plate 143, and vertically upward electric conveyor belts 145 mounted on the end walls of the clamping plates 142 and 143 that are close to each other, and a bag-sorting mechanism is provided behind the palletizing mechanism.

[0042] The packaging mechanism includes a frame 2 fixedly installed on the workshop floor, and a horizontally arranged electric conveyor platform 21 is installed inside the frame 2. The right end of the electric conveyor platform 21 extends to the outside of the frame 2. An electric conveyor platform 22 is installed inside the frame 2, parallel to the lower left end of the electric conveyor platform 21. A temporary storage platform 23 is fixedly installed inside the frame 2, located directly in front of the electric conveyor platform 22. The top of the temporary storage platform 23 is flush with the top of the conveyor belt inside the electric conveyor platform 22. The front end of the temporary storage platform 23 extends to the outside of the frame 2 and is correspondingly arranged with the palletizing mechanism. A baffle 24 is provided on the electric conveyor platform 22. An electric slide rail 25 is fixedly installed inside the frame 2, arranged vertically above the electric conveyor platform 22 and the temporary storage platform 23. A push plate 26 is connected to the sliding end of the electric slide rail 25, which is located on the top of the electric conveyor platform 22 and the temporary storage platform 23.

[0043] Pallets 3 are placed on the ground on both sides of the palletizing mechanism.

[0044] When the device is in operation, the cigarette packs are first sorted by the packing mechanism and then picked up by the stacking mechanism for stacking. In the packing mechanism, the cigarette packs are placed into the electric conveyor platform 21 and conveyed to the left, then fall onto the electric conveyor platform 22. On the electric conveyor platform 22, they are then conveyed to the left. The leftmost cigarette pack on the electric conveyor platform 22 is blocked by the baffle 24. As the cigarette packs continue to be conveyed, multiple cigarette packs will remain on the electric conveyor platform 22. Initially, the pusher plate 26 is positioned behind the cigarette packs above the electric conveyor platform 22. Normally, on the electric conveyor platforms 21 and 22... Under the continuous conveying of the electric conveyor 22 and the restriction of the baffle 24, the four cigarette packs will be arranged side by side on the electric conveyor 22. In this state, the baffle 24 and the left end wall of the temporary storage platform 23 are on the same vertical plane. At this time, the electric slide rail 25 is powered on and starts, driving the push plate 26 to move from back to front, pushing the four cigarette packs from the back, so that the four cigarette packs placed side by side on the electric conveyor 22 can move smoothly to the temporary storage platform 23, and continue to be conveyed forward along the top of the temporary storage platform 23 until they move to the front end of the temporary storage platform 23. Then the electric slide rail 25 drives the push plate 26 to return to the initial state.

[0045] After the cigarette packs are sorted and transported to the front end of the temporary storage platform 23, the palletizing mechanism grabs the four sorted cigarette packs and then performs an orderly stacking operation. During this process, a servo motor is fixed inside the base 1 to drive the electric rotary table 11 to rotate. It can control the electric lifting rail 12 to rotate clockwise and counterclockwise. The sliding end of the electric lifting rail 12 can control the multi-axis robotic arm 13 to move up and down under electric drive. The multi-axis robotic arm 13 is composed of multiple arms that are hinged to each other, and servo motors are installed at the hinges for rotation drive. The end of the multi-axis robotic arm 13 is also hinged to the top plate 141 and driven by the servo motor. The above structure allows the palletizing mechanism to control the grabbing mechanism 14 to move flexibly and adjust its posture.

[0046] During the grasping process, the grasping mechanism 14 is first moved to the top of the four cigarette packs at the front end of the temporary storage platform 23. Then, the pneumatic push rod 144 drives the clamping plate 143 to move away from the clamping plate 142, making the distance between the clamping plates 142 and 143 greater than the length of the cigarette packs. Next, the electric lifting rail 12 controls the multi-axis robotic arm 13 to move the grasping mechanism 14 downwards, so that the "U"-shaped structure formed by the top plate 141, clamping plates 142 and 143 is fitted over the four cigarette packs from top to bottom. Then, the pneumatic push rod 144 is activated, and the... The control clamp 2 143 moves towards the clamp 1 142, clamping the four cigarette packs between the clamp 1 142 and the clamp 2 143. Simultaneously, the front and rear end walls of the cigarette packs are tightly fitted with the conveyor belt inside the electric conveyor belt 1 145. After the electric conveyor belt 1 145 installed on the end walls of the clamp 1 142 and the clamp 2 143 is started, it provides an upward conveying force to the cigarette packs through the conveyor belt, driving the cigarette packs to move upward between the clamp 1 142 and the clamp 2 143. This can effectively prevent the cigarette packs from falling downward during the gripping and moving process, which is conducive to ensuring the stability of the palletizing and conveying process.

[0047] After the gripping mechanism 14 simultaneously grips four cigarette packs, the multi-axis robotic arm 13, with the help of the rotational adjustment of multiple arms and the lifting control of the electric lifting rail 12, can gradually and stably stack the cigarette packs onto the pallets 3 placed on the left and right sides of the stacking mechanism. During the stacking process, each stack is staggered, allowing the upper and lower layers of cigarette packs to be stacked alternately, ensuring stacking stability. During the gripping process of the gripping mechanism 14, the electric conveyor belt 145 provides upward conveying power to the cigarette packs, and the bottom of the top plate 141 is designed as a flat structure, which allows the top plate 141 to provide upward conveying power to the gripping mechanism 14. The upward-moving cigarette packs are blocked, and the four cigarette packs gripped between clamp 142 and clamp 2143 are adjusted to the same height and neat state. This makes the four cigarette packs more neat when they are grabbed and stacked on pallet 3, which helps to ensure the stability of continuous stacking. When releasing the cigarette packs, clamp 2143 can be moved away from clamp 142 by pneumatic push rod 144 to release the grip on the cigarette packs and complete the release operation. Alternatively, electric conveyor belt 145 can be operated to provide downward transport for the cigarette packs, so that the cigarette packs can be quickly released from between clamp 142 and clamp 2143. The operation process is more flexible and convenient.

[0048] In this device, a packing mechanism is installed behind the palletizing mechanism, allowing multiple cigarette packs to be sorted during transport. These packs are then gripped by the gripping mechanism 14 within the palletizing mechanism, enabling simultaneous palletizing of multiple packs. This effectively improves the efficiency of automatic cigarette pack palletizing. Furthermore, during the gripping process, an electric conveyor belt 145 is positioned on the end walls of clamping plates 142 and 143. This belt provides upward transport power to the packs, preventing them from falling off during palletizing. The upward transport of the packs and the stop provided by the top plate 141 ensure that multiple packs are aligned at the same height for more precise release. This combination effectively enhances the stability and accuracy of the palletizing process.

[0049] In the specific implementation process, such as Figure 5 and Figure 7 As shown, the surface of the conveyor belt inside the electric conveyor belt 145 is coated with an adhesive layer. When clamped, the conveyor belt inside the electric conveyor belt 145 is conveyed upwards, and when released, the conveyor belt inside the electric conveyor belt 145 is conveyed downwards. When the device is running, because the surface of the conveyor belt inside the electric conveyor belt 145 is coated with an adhesive layer, the device can further improve the stability of the cigarette pack being clamped between the clamping plate 142 and the clamping plate 143 by means of the slight adhesion between the adhesive layer and the surface of the cigarette pack during the gripping process of the gripping mechanism 14, thus preventing the cigarette pack from falling downwards during the stacking process.

[0050] When the cigarette pack is released, the conveyor belt inside the electric conveyor belt 145 transports it downwards. Combined with the gravity of the cigarette pack, it moves rapidly downwards between clamping plates 142 and 143. The adhesive layer on the surface of the conveyor belt inside the electric conveyor belt 145 smoothly separates from the surface of the cigarette pack. During this process, dust and impurities attached to the surface of the cigarette pack can be carried down, realizing the cleaning operation of the front and rear end walls of the cigarette pack during the stacking process. The operation is efficient and convenient. The dust removal operation on the surface of the cigarette pack is carried out by the adhesive layer, which has a good dust removal effect and does not cause dust and impurities to scatter, thus improving the stability of equipment operation to a certain extent.

[0051] In the specific implementation process, such as Figure 7As shown, a worm gear assembly 146 is installed between the servo motor and the conveyor roller inside the electric conveyor belt 145. The worm gear assembly 146 consists of a meshing worm wheel and a worm. The worm wheel is fixedly connected to the conveyor roller inside the electric conveyor belt 145, and the worm is fixedly connected to the drive shaft of the servo motor inside the electric conveyor belt 145. When the device is running, the rotation of the conveyor belt inside the electric conveyor belt 145 is achieved by driving the servo motor inside it. To ensure the stability of the conveyor belt when lifting the cigarette packs upward, the worm gear assembly 146 is connected between the servo motor and the conveyor roller inside the electric conveyor belt 145. After the servo motor is powered on and started, it drives the worm fixedly connected to its drive shaft to rotate. Then, with the meshing of the worm and the worm wheel, it drives the conveyor roller to rotate, thereby providing power for the rotation of the conveyor belt. During this process, the one-way self-locking property of the worm and worm wheel meshing transmission process makes it difficult for the conveyor belt inside the electric conveyor belt 145 to rotate when the servo motor is not started, which helps to ensure the stability of the device during operation.

[0052] In the specific implementation process, such as Figure 5 - Figure 7 As shown, the height of clamp 142 is less than the height of clamp 2143, and the height of clamp 2143 is greater than the height of the cigarette pack. A support plate 147, parallel to the top plate 141, is slidably connected to the bottom of clamp 2143. A pneumatic push rod 148, perpendicular to clamp 2143, is fixedly installed on clamp 2143, and its telescopic end is fixedly connected to the support plate 147. When the device is running, the height of clamp 142 is equal to the height of the cigarette pack, and the height of clamp 2143 is set to 5 / 4 of the cigarette pack height. When the gripping mechanism 14 grips multiple neatly arranged cigarette packs at the front of the temporary storage platform 23, clamp 142 is closer to the frame 2 than clamp 2143. Clamp 142 will descend to the top of the temporary storage platform 23, while clamp 2143 is located outside the temporary storage platform 23. In the initial state... The pallet 147 is stored at the bottom of the clamping plate 143, which allows the bottom of the clamping plate 143 to reach the bottom of the cigarette pack during the gripping process. Subsequently, the clamping plate 142 works with the clamping plate 143 to clamp and remove the cigarette pack. After the gripping mechanism 14 is disengaged from the top of the temporary storage platform 23, the pneumatic push rod 148 is activated to move the pallet 147 towards the clamping plate 142 and insert it into the bottom of the cigarette pack to further restrict the cigarette pack from falling off. When the cigarette pack is to be released, the pallet 147 needs to be retracted to the bottom of the clamping plate 143 by the pneumatic push rod 148, and then the clamping plate 143 needs to be moved away from the clamping plate 142 to release the clamping of the cigarette pack, or the electric conveyor belt 145 can be driven to transport the cigarette pack downwards and place it stably on the pallet 3 for stacking.

[0053] In the specific implementation process, such as Figure 3 , Figure 4 and Figure 8 As shown, a downward-sloping pneumatic push rod 27 is fixedly installed on the sliding end of the electric slide rail 25. A push plate 26 is fixedly installed on the telescopic end of the pneumatic push rod 27. When the device is running, if the push plate 26 pushes four cigarette packs on the electric conveyor platform 22 to the top of the temporary storage platform 23, the pneumatic push rod 27 is in an extended state. After the push plate 26 pushes the cigarette packs to the front end of the temporary storage platform 23, the electric slide rail 25 will control the push plate 26 to move backward and reset to a position behind the electric conveyor platform 22. To avoid conflict between the backward movement and reset of the push plate 26 and the subsequent conveying of cigarette packs on the electric conveyor platform 22, [further details are needed]. Before the electric slide rail 25 drives the push plate 26 to move backward, the pneumatic push rod 27 switches from an extended state to a retracted state. Through the retraction of the telescopic end of the pneumatic push rod 27, the push plate 26 is driven to move upward, so that the push plate 26 is above the cigarette packs on the electric conveyor table 22 when it moves backward. When the push plate 26 passes the cigarette packs on the electric conveyor table 22 and arrives behind the electric conveyor table 22, the pneumatic push rod 27 switches back to an extended state, pushing the push plate 26 behind the cigarette packs on the electric conveyor table 22, preparing for the next pushing operation of the multiple cigarette packs neatly arranged on the electric conveyor table 22.

[0054] The push plate 26 can be moved up and down by the pneumatic push rod 27, which can avoid the push plate 26 from interfering with the cigarette packs on the electric conveyor table 22 during the reset process. This ensures that the arrangement of the cigarette packs on the electric conveyor table 22 is not affected by the push plate 26, and continuous arrangement of the cigarette packs can be achieved.

[0055] In this device, during the process of the palletizing mechanism grabbing and stacking cigarette packs, as the cigarette packs on the tray 3 continuously pile up, the distance between the placement position of the cigarette packs and the front end of the temporary storage platform 23 continuously changes. This causes the time taken for the grabbing mechanism 14 to grab and stack cigarette packs to vary each time. The time taken is shorter for positions closer to the front end of the temporary storage platform 23, and longer for positions farther away. Therefore, the device can push the sorted cigarette packs onto the temporary storage platform 23 for temporary storage using the push plate 26. The push plate 26 is moved up and down by the pneumatic push rod 27, allowing it to easily cross the temporary storage platform 23 as it moves towards the front end of the platform. The neatly arranged cigarette packs placed on storage platform 23 are arranged and arranged at a constant speed by electric conveyor 21 and electric conveyor 22. After being temporarily stored on temporary storage platform 23, they are pushed to the end of temporary storage platform 23 by push plate 26 for grabbing and stacking. The operation of push plate 26 pushing cigarette packs on temporary storage platform 23 to the front position is coordinated with the operation of grabbing mechanism 14 grabbing cigarette packs at the front of temporary storage platform 23. The frequency of cigarette packs being pushed to the front of temporary storage platform 23 is adaptively adjusted so that after grabbing cigarette packs and stacking them on pallet 3 and resetting them, the grabbing mechanism 14 does not need to wait and stay at the front of temporary storage platform 23, which helps to improve the stacking efficiency of the device.

[0056] In the specific implementation process, such as Figure 5 , Figure 8 and Figure 10 - Figure 11 As shown, both the conveyor belt and the temporary storage platform 23 within the electric conveyor platform 22 have evenly distributed air holes 28. Both the electric conveyor platform 22 and the temporary storage platform 23 are equipped with air boxes 29 located below the air holes 28. During operation, an external air pump is connected to the air box 29, allowing for a continuous supply of airflow. The airflow is ultimately ejected through the air holes 28 connected to the air box 29. Within the electric conveyor platform 22, the high-speed airflow is ejected through the evenly distributed air holes 28 at the top of the conveyor belt, acting on the bottom of the cigarette packs being conveyed on the electric conveyor platform 22. This airflow affects both the cigarette packs and the electric conveyor platform. An airflow layer is formed between the conveyor belts inside the second conveyor platform 22, which can reduce the contact friction between the cigarette packs and the conveyor belts inside the electric conveyor platform 22 to a certain extent. Similarly, in the temporary storage platform 23, the high-speed airflow is ejected through the air holes 28 evenly opened at the top of the temporary storage platform 23, and acts on the bottom of the cigarette packs conveyed on the temporary storage platform 23, forming an airflow layer between the cigarette packs and the temporary storage platform 23. This can reduce the contact friction between the cigarette packs and the top of the temporary storage platform 23 to a certain extent. With the cooperation of both, the smoothness of the device in pushing the sorted cigarette packs from the electric conveyor platform 22 to the temporary storage platform 23 and continuously moving the cigarette packs forward on the temporary storage platform 23 can be effectively improved.

[0057] In the specific implementation process, such as Figure 3 , Figure 8 - Figure 9 and Figure 12 As shown, baffle 24 is slidably installed on electric conveyor platform 22. Electric slide rail 24 is fixedly installed in the frame 2, parallel to the electric conveyor platform 22. The sliding end of electric slide rail 24 is fixedly connected to baffle 24. Slide platform 41 is slidably installed in the frame 2, located between electric conveyor platform 1 21 and electric conveyor platform 22. Pneumatic push rod 42 is fixedly installed in the frame 2, parallel to the electric conveyor platform 1 21. The telescopic end of pneumatic push rod 42 is fixedly connected to slide platform 41. Roller 43 is rotatably installed in the frame 2, located between electric conveyor platform 1 21 and slide platform 41. Roller 43 is located below the left end of electric conveyor platform 1 21. The outer surface of roller 43 is coated with adhesive. Horizontally installed electric conveyor belt 2 44 is installed on the top of slide platform 41.

[0058] During operation, as the cigarette packs are conveyed from electric conveyor platform 1 (21) to electric conveyor platform 2 (22), the slide 41 at the bottom of electric conveyor platform 1 (21) moves to the left under the push of pneumatic push rod 42, protruding from the top of electric conveyor platform 22. This causes the cigarette packs conveyed on electric conveyor platform 1 (21) to fall onto slide 41 first. Then, pneumatic push rod 42 manipulates slide 41 to move to the right, retracting slide 41 into the bottom of electric conveyor platform 1 (21). The cigarette packs at the top of slide 41, obstructed by the left end of electric conveyor platform 1 (21), fall downwards onto electric conveyor platform 2 (22). 2. During this process, the electric slide rail 24 is powered on and drives the baffle 24 to move along the electric conveyor platform 22. This works in conjunction with the left and right pushing of the slide platform 41 to form a clamping effect on both sides. This allows the cigarette packs that fall onto the top of the electric conveyor platform 22 to quickly and stably gather together. This improves the efficiency of organizing multiple cigarette packs neatly on the electric conveyor platform 22. Furthermore, by guiding the falling cigarette packs through the slide platform 41, the height of each cigarette pack falling can be reduced, preventing excessive impact during the transfer of the cigarette packs and ensuring the stability of the cigarette pack conveying and organizing process.

[0059] A camera is fixedly installed inside the frame 2 above the slide table 41. The camera can detect the status of the cigarette packs on the slide table 41. When the cigarette pack is at the top of the slide table 41, the electric conveyor belt 44 can transport the cigarette pack to the right, so that the cigarette pack is in close contact with the roller 43. Then, with the help of the rotation of the roller 43, the cigarette pack can be turned over and adjusted on the slide table 41, and the cigarette pack with incorrect posture can be adjusted to the correct position, so as to achieve more precise sorting operation of the cigarette packs and improve the stability of the subsequent stacking process.

[0060] In this device, by attaching the adhesive layer to the outer surface of the roller 43, the gripping force of the roller 43 on the surface of the cigarette pack during rotation can be effectively improved, which in turn helps to improve the stability of the cigarette pack being flipped and adjusted to the correct posture. At the same time, during the flipping and adjustment of the cigarette pack, the slight adhesion formed by the adhesive layer when it comes into contact with the surface of the cigarette pack can effectively remove the dust attached to the four sides of the cigarette pack, which is beneficial for dust removal and cleaning operations during the cigarette pack conveying and sorting process, and will not cause dust to scatter, thus helping to ensure the cleanliness of the cigarette pack.

[0061] Specifically, the working principle of this invention is as follows:

[0062] Cigarette pouches are continuously fed in from the right end of the electric conveyor platform 21. After being conveyed to the left by the electric conveyor platform 21, they fall onto the slide platform 41. The cigarette pouches are detected by a camera on the slide platform 41 to verify whether the cigarette pouches are in the correct position. If the cigarette pouches are not in the correct position, the electric conveyor belt 44 will convey the cigarette pouches to the right on the slide platform 41, making the cigarette pouches in close contact with the rollers 43. With the help of the rotation of the rollers 43, the cigarette pouches are driven to flip over to the correct position on the top of the slide platform 41. During the flipping process, the adhesive layer on the outer surface of the rollers 43 is used to clean the dust from the side walls of the cigarette pouches. When the cigarette pouches are in the correct position on the slide platform 41, the pneumatic push rod 42 will control the slide platform 41 to move to the right. With the obstruction of the left end of the electric conveyor platform 21 and the rollers 43, the cigarette pouches on the slide platform 41 fall onto the electric conveyor platform 22. During this process, the electric slide rail 24 will drive the baffle 24 to... The movement to the right restricts the cigarette packs on both sides of the slide table 41, ensuring that the cigarette packs on the slide table 41 can fall onto the electric conveyor table 22 in the correct posture. Continuing the above operation, four cigarette packs are arranged side by side and attached to each other on the electric conveyor table 22. Then, the electric slide rail 25 is activated, and the push plate 26 is moved forward by the pneumatic push rod 27, pushing the arranged cigarette packs to the front end of the temporary storage platform 23. Then, the electric slide rail 25 moves the push plate 26 backward, resetting to the rear of the electric conveyor table 22. During this process, the pneumatic push rod 27 is in a retracted state, allowing the push plate 26 to pass over the cigarette packs piled on the electric conveyor table 22. During the cigarette pack transportation process, the airflow supplied in the air box 29 is sprayed upward through the air hole 28, reducing the contact friction force on the bottom of the cigarette pack and improving the smoothness of the cigarette pack movement.

[0063] Then the stacking mechanism is activated. The electric rotary table 11 controls the rotation of the electric lifting rail 12, which in turn controls the lifting of the multi-axis robotic arm 13. The multi-axis robotic arm 13 then controls the gripping mechanism 14 to swing flexibly, adjusting it to the front position of the temporary storage platform 23. Through the mutual approach of clamping plates 142 and 143, the four neatly placed cigarette packs at the front of the temporary storage platform 23 are simultaneously gripped. The gripping mechanism 14 grabs the cigarette packs and stacks them onto the pallet 3. During the process of the gripping mechanism 14 moving the cigarette packs, the electric conveyor belt 145 installed on clamping plates 142 and 143 transports the cigarette packs upwards, preventing them from falling down. The electric conveyor belt 145 also transports the cigarette packs upwards. The stop plate 141 at the top of the cigarette pack can correct the cigarette pack held between the clamping plates 142 and 143 to the same height, improving the accuracy of the cigarette pack release and stacking. During the handling of the cigarette pack by the gripping mechanism 14, the pneumatic push rod 148 will control the pallet 147 to move towards the clamping plate 142, protruding outward at the bottom of the clamping plate 143 to prevent the cigarette pack from falling off. During the release of the cigarette pack by the gripping mechanism 14, the downward conveying of the electric conveyor belt 145 can quickly separate the cigarette pack from the adhesive layer on the surface of the conveyor belt. This not only increases the release speed of the cigarette pack, but also cleans the dust and impurities attached to the front and rear end walls of the cigarette pack, continuously ensuring the cleanliness of the cigarette pack surface.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
