Based on the weighing data from the second weighing conveyor line 603 and the third weighing conveyor line 604, manual weight balancing can be performed on the boxes loaded with shredded tobacco after the repackaging.

[0087] The specific working process of this device is as follows:

[0088] The tobacco cutting and packaging device of this embodiment is suitable for unpacking, cutting, and packaging of tobacco in a carton structure consisting of an inner box with an open top and an outer box nested together.

[0089] In operation, a forklift is used to place the entire pack of cigarettes at the loading station, with the bottom of the outer box facing upwards. The loading and weighing conveyor line 1 weighs the entire pack online. At the strapping removal station, the strapping on the pack is removed manually. After the entire pack is weighed, it is conveyed to the outer box removal mechanism 2, which lifts and removes the outer box. Then it is conveyed to the inner box flipping mechanism 3, with the opening of the inner box facing upwards. The inner box is flipped 180 degrees by the inner box flipping mechanism 3, so that the bottom of the inner box faces upwards. Then it is output to the inner box removal mechanism 4, which lifts and removes the inner box. Then it is conveyed to the protective film removal station of the tobacco slicing mechanism, where the protective film on the outer layer of the tobacco slices is removed manually. Then the tobacco slicing mechanism cuts the tobacco slices, and the cut tobacco slices are conveyed to the packaging and weighing conveyor line for packaging and weighing.

[0090] This invention's device enables online weighing, unpacking, cutting, and weighing of entire tobacco packs. The entire process is seamlessly integrated, with each step operating continuously, thus improving the efficiency of cutting and packaging tobacco.

[0091] Specifically, at the cigarette pack loading station, workers use forklifts or other transport vehicles to place the cigarette packs onto the designated loading station (or directly onto the conveyor line from the original production line's tray removal location). This station is equipped with forklift travel limits and fork leg height limits based on the forklift model to ensure the cigarette packs are placed smoothly onto the conveyor line. Conveyor line guards and straightening strips are also installed on the subsequent line sections.

[0092] Specifically, the manual removal of cable ties typically involves operators using appropriate tools and specialized untying devices. First, upon receiving the cigarette packs from the previous conveyor, the operator carefully inspects the material and tension of the cable ties to ensure safety. Then, they select the most suitable tool and cut or untie the cable ties at the appropriate angle and with appropriate force, ensuring the ties are removed completely and orderly while preserving the integrity and stability of the goods or packages as much as possible. The removed cable ties are then placed in a recycling unit to prevent scattered ties from causing tripping hazards.

[0093] The first conveyor line 201 is responsible for transferring cigarette packs with the strapping removed between the feeding and weighing conveyor line 1 and the inner box flipping mechanism 3; the first unpacking robot 204 is used to remove the outer box of the cigarette pack on the first conveyor line 201 and move the outer box to the second conveyor line 202, which is responsible for outputting the outer box.

[0094] The third conveyor line 401 is responsible for transferring the inner box containing tobacco between the inner box flipping mechanism 3 and the tobacco cutting mechanism. The second unpacking robot 404 is responsible for removing the inner box on the third conveyor line 401 and moving the inner box to the fourth conveyor line 402. The fourth conveyor line 402 is responsible for outputting the inner box.

[0095] The first conveyor line 201, the second conveyor line 202, the third conveyor line 401, and the fourth conveyor line 402 are all roller conveyor lines and include multiple rollers spaced apart in a horizontal direction. The first conveyor line 201 and the third conveyor line 401 are electrically driven roller conveyor lines.

[0096] The system automatically removes the outer and inner boxes containing the finished cigarette packs. This process not only reduces labor costs and improves efficiency but also ensures the safety and hygiene of the cigarette packs during unpacking. The outer box is peeled off layer by layer or removed entirely, while ensuring the internal cigarette pack packaging remains intact, facilitating subsequent sorting, storage, or direct loading for transportation. Furthermore, the system features self-diagnosis and alarm functions, enabling real-time monitoring of its operational status and ensuring the continuity and stability of the unpacking operation.

[0097] The horizontal conveying channel of the flipping conveyor 302 is responsible for receiving the cigarette packs with the strapping and outer box removed from the first conveyor line 201. At this time, the top of the inner box is open and facing upwards. To remove the inner box, the inner box needs to be flipped 180 degrees so that its bottom surface faces upwards. The flipping conveyor 302 is responsible for flipping the inner box 180 degrees and conveying the flipped inner box with its bottom surface facing upwards to the inner box removal mechanism 4 through its horizontal conveying channel for inner box removal.

[0098] Both the first unpacking robot 204 and the second unpacking robot 404 are three-axis robots with suction cups as end effectors. The suction cups of the first unpacking robot 204 and the second unpacking robot 404 can hold the outer surface of the box and lift and transfer it to realize the unpacking function.

[0099] The roller assembly serves to support the tilting conveyor 302 above the third support frame, and the tilting conveyor 302 achieves rotation through the roller assembly; in use, the motor is used to drive and control the rotation angle of the tilting conveyor 302.

[0100] The roller assembly includes four grooved rollers, namely, grooved roller 1, grooved roller 2, grooved roller 3, and grooved roller 4, which are rotatably mounted on the upper end of the third support frame.

[0101] Grooved wheel one and grooved wheel two are arranged at intervals along the width direction of the third support frame and correspond to one side of the length direction of the third support frame; the outer periphery of the left annular plate 3021 is adapted to be snapped onto grooved wheel one and grooved wheel two;

[0102] Geneva wheel three and Geneva wheel four are arranged at intervals along the width direction of the third support frame and correspond to the other side of the length direction of the third support frame; the outer periphery of the right annular plate 3021 is adapted to be snapped onto Geneva wheel one and Geneva wheel two.

[0103] Both box-clamping conveyor lines 3023 can be raised and lowered to connect between the first conveyor line 201 and the third conveyor line 401 to transfer cigarette packs with the strapping and outer box removed. The two can work together to clamp the cigarette packs with the strapping and outer box removed between them. The flipping driver drives the two annular plates 3021, thereby causing the clamped cigarette packs with the strapping and outer box removed to flip. After flipping 180 degrees, the arbitrary box-clamping conveyor line 3023 is raised and lowered so that the arbitrary box-clamping conveyor line 3023 is aligned with the third conveyor line 401 and outputs the cigarette packs to the third conveyor line 401.

[0104] Both box-type clamping conveyor lines 3023 are planar conveyor lines equipped with conveyor roller structures. The telescopic drive directions of the two telescopic drive mechanisms 3024 are relative to the directions of the two box-type clamping conveyor lines 3023. Both telescopic drive mechanisms 3024 are equipped with guide posts to improve clamping stability. The guide posts slide through guide holes on the corresponding connecting plates 3022.

[0105] In the tobacco pack slitting process, the flipping of the pack with its inner box plays a crucial role. This process, through a highly automated conveyor system and a precisely designed flipping mechanism, achieves a precise 180° flip of the entire pack before transport. As the inner box moves along the conveyor line to the flipping area, pre-set sensors immediately capture its position and send a signal to the control system.

[0106] The control system responds quickly, activating the flipping mechanism. This mechanism typically consists of a robust frame, a precise transmission device, and a reliable locking and unlocking mechanism, ensuring a stable and safe flipping process. Upon receiving the command, the flipping mechanism starts, smoothly lifting the entire box of cigarettes and precisely flipping it 180° along a preset trajectory.

[0107] Throughout the entire flipping process, the inner box and cigarette packs are firmly secured, effectively preventing scattering or damage that may occur due to inertia or improper operation. After flipping, the inner box and cigarette packs land smoothly on the conveyor line again, improving production efficiency, reducing the need for manual intervention, and ensuring the consistency of the cigarette packs' orientation in subsequent processing through precise flipping control.

[0108] The fifth conveyor line 501 includes a frame, a drive roller, a driven roller, an annular conveyor belt, and a drive motor. The drive roller and the driven roller are rotatably mounted at the top of both ends of the frame along its length. The axial direction of both the drive roller and the driven roller is along the width direction of the frame. The annular conveyor belt is fitted onto the drive roller and the driven roller. The drive motor is mounted on the frame and its shaft is connected to the drive roller, thereby driving the annular conveyor belt to operate.

[0109] The fourth support 502 consists of a first column, a second column, a crossbeam, and a base plate. The top surface of the base plate is attached to and supported on the bottom surface of the upper part of the corresponding annular conveyor belt. The first and second columns are located on both sides of the width direction of the annular conveyor belt, and their lower ends are vertically fixed to the base plate. The crossbeam is fixed to the upper ends of the first and second columns. A lifting driver is installed on the crossbeam. A cutter 503 is located between the first and second columns. The lifting end of the lifting driver is connected to the cutter 503 to drive it to move up or down away from or near the surface of the annular conveyor belt.

[0110] Specifically, guide grooves are provided on the opposite side walls of the first and second columns along the height direction, and the two ends of the cutter 503 are slidably connected to the guide grooves of the first and second columns respectively.

[0111] Specifically, the manual removal of the protective film from tobacco flakes is a crucial step in tobacco processing or storage. Tobacco flakes are typically covered with a protective film to maintain humidity, prevent contamination, and ensure quality. During this operation, workers first don protective gear such as gloves, masks, and dust-proof clothing to protect themselves from potential dust or harmful substances. Using specialized tools, such as blades or dedicated protective film peelers, workers manually cut or peel the film along the boundary between the film and the tobacco pile. Care must be taken to control the force and angle during this process to avoid damaging the tobacco flakes underneath or disrupting their original arrangement. Simultaneously, workers must maintain a clean work area, promptly cleaning up any fallen protective film fragments to ensure a safe and hygienic working environment. The entire removal process requires workers to have extensive experience and excellent teamwork to ensure the efficient and successful completion of the task.

[0112] The drive motor for the circular conveyor belt is a servo motor, used to precisely control the conveying direction and distance of the circular conveyor belt; the fourth bracket 502 also includes a controller and a through-beam photoelectric sensor. The transmitting end and receiving end of the through-beam photoelectric sensor are installed one-to-one with the first column and the second column, used to detect the front and rear positions of the tobacco blocks conveyed between them, thereby assisting in locating the cutting position of the tobacco blocks; the controller is electrically connected to the through-beam photoelectric sensor and the drive motor, and can accurately locate the position of the tobacco blocks directly below the cutter 503 by controlling the operation of the drive motor based on the position data of the tobacco blocks measured by the through-beam photoelectric sensor.

[0113] The fifth conveyor line 501 of the tobacco sheet cutting mechanism is responsible for receiving the tobacco sheets from the inner box removal mechanism 4 after removing the inner box. At this time, only the protective film remains on the outside of the tobacco sheets. The protective film is carefully removed manually at the protective film removal station. After the protective film is removed, the tobacco sheets are conveyed to the cutter 503 for cutting via the fifth conveyor line 501.

[0114] Specifically, the automatic slitting process for tobacco leaf packs typically involves unpacking and repackaging a batch of tobacco leaf packs in a previous process. After repackaging, the conveyor belt from the previous process automatically feeds the packs into the slitting equipment, where the packs are precisely cut using a blocking mechanism and a sensor position determination mechanism.

[0115] During the automated slitting process, the system first scans and identifies the cigarette packs to ensure accurate positioning, then activates the cutting mechanism to complete the cutting action quickly and smoothly. This automated slitting process not only significantly improves production efficiency and reduces manual intervention, but also reduces errors in subsequent processes by precisely controlling the cutting dimensions, thus improving product uniformity and consistency and meeting the tobacco industry's stringent requirements for high-quality raw materials.

[0116] One end of the first weighing conveyor line 602 is placed at one end of the sixth conveyor line 601 to convey empty packaging boxes onto the sixth conveyor line 601. One side of the sixth conveyor line 601 is connected to the other end of the fifth conveyor line 501 to receive the slicing tobacco blocks output from the fifth conveyor line 501 and to load the slicing tobacco blocks into empty packaging boxes. The second weighing conveyor line 603 is connected to the other end of the sixth conveyor line 601 to weigh the boxed slicing tobacco blocks. The other end of the second weighing conveyor line 603 is connected to one end of the third weighing conveyor line 604 to weigh the boxed slicing tobacco blocks.

[0117] The first weighing conveyor line 602 is used to convey the weight of empty packaging boxes loaded with diced cigarettes to record the tare weight data. First, the first weighing conveyor line 602 sequentially conveys two empty packaging boxes to the sixth conveyor line 601. The sixth conveyor line 601 conveys the empty packaging boxes to the other end of the corresponding fifth conveyor line 501 and receives the diced cigarette blocks output from the fifth conveyor line 501 for dicing. One of the diced packaging boxes is then conveyed to the third weighing conveyor line 604 for weighing to avoid the second weighing conveyor line 603. The second weighing conveyor line 603 receives the next diced packaging box loaded with diced cigarettes and weighs and tares it.

[0118] In some embodiments, the sixth conveyor line 601 includes a sixth conveyor line 601 and a flipping and packing mechanism.

[0119] The sixth conveyor line 601 is a roller conveyor line and includes multiple rollers spaced apart in the horizontal direction; the flipping and packing mechanism includes a drive shaft, a drive motor and a right-angle flipping arm 605;

[0120] The drive motor is mounted on the lower frame of the sixth conveyor line 601; the drive shaft is horizontally arranged and perpendicular to the roller; the drive shaft is located below the roller of the sixth conveyor line 601 and close to the other end of the fifth conveyor line 501. The middle part of the right-angle tilting arm 605 is vertically fixed to the drive shaft, and the two mutually perpendicular arms of the right-angle tilting arm 605 can move through the gap between the corresponding two adjacent rollers.

[0121] Both arms of the right-angle tilting arm 605 can rotate to a position parallel to the bottom of the drum and a position extending vertically above the drum; the drive motor is connected to the drive shaft via a synchronous belt to drive and control its rotation angle, achieving a 90-degree range tilting of the two arms.

[0122] The two arms of the right-angle flipping arm 605 can support the packaging box on the sixth conveyor line 601, and flip the packaging box with the top opening facing upwards towards the other end of the fifth conveyor line 501, so that the top opening of the packaging box faces the other end of the fifth conveyor line 501, so that the sliced ​​tobacco output from the fifth conveyor line 501 enters the packaging box at a right angle, and then drives the packaging box to flip and reset to the position with the top opening facing upwards.

[0123] The dispensing and weighing conveyor line also includes an output line, one end of which is connected to the other end of the third weighing conveyor line 604.

[0124] The weighing data from the second weighing conveyor line 603 and the third weighing conveyor line 604 can be used to manually balance the weight of the packaging boxes containing the shredded tobacco after the repackaging.

[0125] After the initial splitting and slicing of the cigarette packs, they need to be evenly distributed into two separate cigarette packaging boxes for use in subsequent processes. The manual weighing and balancing of the packages will be carried out in a way that is as even as possible. A high-precision electronic scale will be used to weigh each of the initially packaged small packages one by one, record the actual weight, and compare it with the target weight.

[0126] Specifically, two empty cigarette boxes are manually placed at the beginning of the first weighing conveyor line 602. The empty cigarette boxes (including the pallets) are weighed at the weighing position of the first weighing conveyor line 602 to confirm their weight. When they reach the sixth conveyor line 601, half of the cut cigarette packs enter the empty cigarette box and then move to the weighing position of the third weighing conveyor line 604. The second empty cigarette box, after being filled with the slit cigarettes, enters the weighing position of the second weighing conveyor line 603. By subtracting the weight measured on the first weighing conveyor line 602, the tare operation of the first and second cigarette boxes is completed, and the weight is matched. After completion, the manual transports the counterweighted cigarette box to a suitable location and repeats the above work.
