Description

Technical Field

[0001] This invention relates to tobacco leaf arranging on a tobacco leaf re-copying line, and more specifically, to a tobacco leaf arranging machine, a tobacco leaf arranging system, and a tobacco leaf arranging method. Background Technology

[0002] Arranging tobacco leaves during the re-drying process involves removing them from the tobacco baskets according to different quality and quantity requirements and placing them onto a conveyor belt to ensure that the leaf bases are aligned and facing the same direction. Currently, most tobacco re-drying plants in China mainly use manual labor for arranging tobacco leaves, which results in low production efficiency, poor quality, high labor intensity, and harsh working conditions.

[0003] Currently, some tobacco re-drying plants are experimenting with using robotic gripper technology to automate the tobacco leaf arrangement process. The tobacco leaf baskets are transported by forklift or automated logistics to the side of the conveyor belt equipped with the robotic gripper. The robotic gripper uses image recognition to locate the tobacco leaves, then grips, lifts, rotates, lowers, and adjusts their position before placing them onto the conveyor belt, completing the automated arrangement process. There are also attempts to use suction cups instead of robotic grippers for this purpose. For example, Chinese patent document CN205455992U discloses an automatic tobacco leaf arrangement machine that uses a robotic gripper to grab tobacco leaves from the tobacco baskets and place them on the operating table.

[0004] Because of the stickiness of the tobacco leaves to the e-liquid, whether it is a robotic arm or a suction cup, during the process of grabbing and lifting the tobacco leaves, some tobacco leaves that have not been grabbed by the robotic arm or suction cup will stick together and be scattered. The tobacco leaves placed on the belt conveyor are messy and disorderly, which seriously affects the quality of subsequent tip cutting. Moreover, the above methods cannot clean the tobacco leaves in the tobacco basket completely, and manual cleaning is required. Summary of the Invention

[0005] The purpose of this invention is to provide a tobacco leaf arranging machine that can automatically arrange tobacco leaves into bundles, thereby achieving automatic and orderly placement of tobacco leaves.

[0006] The tobacco leaf stacking machine provided by the present invention includes a discharge mechanism and a rotatable tobacco basket rotating body; the tobacco basket rotating body is provided with a channel for the tobacco leaf basket to enter and exit, and the tobacco basket rotating body has a space to accommodate the tobacco leaf basket; the discharge mechanism is installed on the tobacco basket rotating body and located at the upper part of the tobacco basket rotating body, and the discharge mechanism includes a conveying mechanism; when the tobacco basket rotating body rotates to the discharge position, the discharge mechanism rotates to the lower part of the tobacco basket rotating body, and the conveying mechanism is used to receive tobacco leaves falling from the tobacco leaf basket with the top opening facing downward.

[0007] In the initial position, the conveying mechanism is located above the rotating tobacco basket. The tobacco basket is placed into the rotating body, which then rotates, causing the tobacco basket and the conveying mechanism to rotate together. With the opening of the tobacco basket facing downwards, the tobacco leaves gradually fall onto the conveying mechanism, which then gradually outputs the tobacco leaves onto the production line, arranging them in an orderly fashion. The tobacco leaves fall onto the conveying mechanism immediately after leaving the tobacco basket, without leaving the conveying surface, ensuring that the tobacco leaves remain neatly arranged in bundles.

[0008] The tobacco basket typically holds multiple rows of tobacco leaves. The discharge mechanism of this invention also includes a tray, which is arranged side by side with the conveying mechanism. The conveying mechanism and the tray can move along the rotation axis of the tobacco basket. When the tobacco basket rotates to the discharge position, the conveying mechanism is used to receive one row of tobacco leaves falling from the top-opening tobacco basket, and the tray is used to support the other rows of tobacco leaves. This arrangement allows multiple rows of tobacco leaves to be arranged in sequence, with one row of tobacco leaves placed at a time.

[0009] Preferably, the conveying mechanism is mounted on the rotating body of the tobacco basket via a sliding mechanism, and the conveying mechanism is driven to move by a second driving mechanism; it also includes a third driving mechanism for driving the extension and retraction of the pallet, the third driving mechanism being mounted on the conveying mechanism, thereby enabling the conveying mechanism and the pallet to move synchronously.

[0010] The present invention provides a pushing mechanism at one end of the rotating tobacco basket, the pushing mechanism including a lifting mechanism and a fourth driving mechanism; when the rotating tobacco basket rotates to the discharge position, the fourth driving mechanism drives the lifting mechanism to enter between the currently discharged row of tobacco leaves and the bottom plate of the tobacco basket, and drives the lifting mechanism to descend so that the tobacco leaves fall onto the conveying mechanism. This allows for control of the tobacco leaf falling speed and also pushes out tobacco leaves that are stuck to the tobacco basket or intersecting with other tobacco leaves.

[0011] Preferably, the fourth driving mechanism includes a telescopic driving mechanism and a lifting driving mechanism. The telescopic driving mechanism is used to drive the lifting mechanism to enter and exit the tobacco basket, and the lifting driving mechanism is used to drive the lifting mechanism to move up and down.

[0012] To prevent the tobacco leaves from damaging the tobacco basket guardrail during rotation or at the discharge position, a support plate and a first drive mechanism for extending and retracting the support plate are installed on the rotating body of the tobacco basket. When the rotating body of the tobacco basket rotates to the discharge position, the support plate is used to support the tobacco basket guardrail that has rotated to the lower part.

[0013] Preferably, the tobacco basket rotating body includes two rotating rings connected by a connecting bracket. The tobacco basket rotating body can be driven to rotate by driving the rotating rings to rotate.

[0014] Preferably, the lower and upper parts of the tobacco basket rotating body are provided with limiting components, which are used to fix the tobacco basket.

[0015] Due to the presence of e-liquid, tobacco leaves may stick together. This invention provides a hand-shaped scraper plate on the conveying mechanism, with the opening of the scraper plate facing the conveying direction of the conveying mechanism. The scraper plate is used to separate the sticky tobacco leaves, and the height of the scraper plate determines the thickness of the separated tobacco leaves.

[0016] The present invention also provides a tobacco leaf arranging system, including a conveying device, and a tobacco leaf arranging machine of the present invention is arranged above the conveying device. When the tobacco basket rotator rotates to the discharge position, the conveying mechanism of the tobacco leaf arranging machine rotates to the top of the conveying device. The conveying mechanism and the conveying device have an angle or are parallel. The conveying mechanism is used to output the tobacco leaves it receives to the conveying device.

[0017] Preferably, the tobacco basket rotating body of the tobacco leaf arranging machine can move along the rotation axis of the tobacco basket rotating body, thereby adjusting the conveying mechanism to a position corresponding to the conveying device.

[0018] Preferably, the tobacco basket rotating body is mounted on a power bed, and the power bed is provided with a rotating support wheel that drives the tobacco basket rotating body to rotate. The power bed is mounted on a sliding track, thereby driving the tobacco basket rotating body to move along the rotation axis of the tobacco basket rotating body through the power bed.

[0019] Preferably, it also includes a feeding device for feeding the tobacco basket into the rotating body of the tobacco basket.

[0020] The present invention also provides a method for arranging tobacco leaves, which uses the tobacco leaf arranging system described in the present invention. The method is characterized in that: when the tobacco basket rotating body is in the initial position, the tobacco basket is sent into the tobacco basket rotating body; the tobacco basket rotating body is rotated to the discharge position, and the tobacco leaves in the tobacco basket gradually fall onto the conveying mechanism. The conveying mechanism transports the tobacco leaves to the conveying device below, thereby gradually arranging the tobacco leaves onto the conveying device.

[0021] Preferably, multiple rows of tobacco leaves are placed in the tobacco basket. Before rotating the tobacco basket to the discharge position, the driving conveyor mechanism is moved to the top of one of the rows of tobacco leaves that need to be output, the driving pallet is pressed on the other rows of tobacco leaves, and the driving tobacco basket is moved so that the position of the conveyor mechanism corresponds to that of the conveying device.

[0022] Preferably, when the tobacco leaves fall, a space is formed between the bottom plate of the tobacco leaf basket and the tobacco leaves. The lifting mechanism is driven into this space and then driven to descend so that the tobacco leaves fall to the conveying mechanism.

[0023] Preferably, when the tobacco basket rotator rotates to the discharge position and there is an angle between the conveying mechanism and the conveying device, after a certain row of tobacco leaves has been discharged, the tobacco basket rotator is rotated until the mechanism is parallel to the conveying device, and then the tobacco basket rotator is rotated back to the initial position.

[0024] The present invention has the following beneficial effects: (1) The automatic tobacco leaf stacking machine realizes the whole row of tobacco leaves clamped and discharged from the box. During the whole process of stacking and discharging the leaves, the tobacco leaves do not leave the conveyor surface, ensuring that the tobacco leaves are stacked in a neat and orderly manner and that there is less dust in the working environment. (2) The whole box is lifted and discharged in a neat and orderly manner, which improves the efficiency of tobacco leaf stacking and greatly meets the stacking needs of production lines with a production capacity of 16,000 kg / h and above. (3) The equipment has a high degree of automation and high stacking quality, which greatly reduces the labor intensity of workers and avoids the stacking quality fluctuation caused by the mood of workers during manual stacking. (4) After each row of tobacco leaves is stacked, the automatic tobacco leaf stacking machine automatically cleans the box, and there are no tobacco leaves left in the tobacco leaf basket. (5) By controlling the speed of the discharge conveyor belt, the stacking speed of the tobacco leaves can be controlled. Combined with logistics management, automatic tobacco leaf formulation can be realized, which improves the accuracy of tobacco leaf formulation. Attached Figure Description

[0040] The tobacco leaf stacking machine provided by this invention discharges tobacco leaves from the tobacco leaf basket onto a belt conveyor.

[0041] like Figure 1 , 2 As shown, the tobacco leaf basket is a U-shaped frame with a bottom plate 120 but no top cover. Two sides of the frame have mesh railings 130, while the other two sides are unrailed. The tobacco leaves 140 are arranged in rows inside the frame along the side without railings, typically in three rows, with longer leaves arranged in two rows. Figure 2 The tobacco leaves in the basket were arranged in three rows. The leaf bases and tips were pointing in the same direction, and there was random overlap between the leaf bases and tips between the rows.

[0042] like Figure 3 , 4 As shown, the tobacco leaf arranging machine provided by the present invention includes a tobacco basket rotating body 4, a material discharge mechanism 5, and a pushing mechanism 6.

[0043] like Figure 6 , 7 As shown, and in combination Figure 3 , 45. The tobacco basket rotating body 4 is rotatably configured, including two rotating rings 4-1, which are connected by several connecting brackets 4-2. Each connecting bracket 4-2 is equipped with an upper limit block 4-6 and a lower limit block 4-5. The tobacco basket is placed within the receiving space of the rotating body, and the upper and lower limit blocks limit the movement of the tobacco basket to prevent it from shaking. The rotating body has a channel for the tobacco basket to enter and exit; in this embodiment, the channel is located at the end, such as... Figure 4 As shown, the tobacco basket is fed into the rotating body of the tobacco basket from the end of the right-side rotating ring by the feeding lifting roller conveyor. The shape of the rotating body of the tobacco basket can be set as needed, as long as it can rotate around its own rotation axis. In this embodiment, the purpose of setting two rotating rings is mainly to facilitate the driving of the rotating body of the tobacco basket. The rotating body of the tobacco basket can also be set into a cylindrical shape. A support plate 4-3 is also set on the connecting bracket 4-2. The support plate 4-3 is driven to extend and retract by the first driving mechanism. Figure 6 The first drive mechanism shown is a telescopic cylinder 4-4 (four telescopic cylinders 4-4 are shown in the figure). Combined with... Figure 3 , 4 It can be seen that after the tobacco basket is fed into the rotating body 4, the opening of the tobacco basket faces upward. However, as the tobacco basket rotates with the rotating body, one side of the guardrail will rotate downward and bear the pressure of the tobacco leaves. In addition, as... Figure 11 As shown, when the tobacco basket rotator rotates to the discharge position, the opening of the tobacco basket faces downwards, and the tobacco basket is usually tilted. At this time, the lower guardrail bears the squeezing force of the tobacco leaves in the tobacco basket and is easily damaged. This invention provides a support plate 4-3. Before the tobacco basket rotator rotates, the support plate 4-3 extends to abut one side of the guardrail. During rotation and after reaching the discharge position, the support plate 4-3 provides support and protection. When the support plate 4-3 retracts, it does not affect the entry and exit of the tobacco basket from the tobacco basket rotator 4. Whether the support plate 4-3 is placed on one side, or on both sides, depends on the rotation method. In this embodiment, the tobacco basket rotator rotates counterclockwise to the discharge position and then clockwise back to its original position. Therefore, in this embodiment, the support plate 4-3 is placed on the left side (within the left side). Figure 3 , 6 (From a perspective).

[0044] like Figure 3 , 4As shown in Figures 8 and 9, the discharge mechanism 5 includes a conveying mechanism. In this embodiment, a discharge conveyor belt 5-1 is used as the conveying mechanism. The discharge conveyor belt 5-1 is movably mounted on the connecting bracket of the tobacco basket rotary body 4. In its initial position, it is located above the tobacco basket rotary body 4, and its direction of movement is parallel to the rotation axis of the tobacco basket rotary body 4. A slide rail 5-2 extending along the rotation axis of the tobacco basket rotary body is provided on the tobacco basket rotary body. The discharge conveyor belt 5-1 is mounted on the slide rail 5-2 and is driven to move on the slide rail by a second drive mechanism. The second drive mechanism can be a conveyor belt drive cylinder 5-4. The slide rail 5-2 can also be replaced by other sliding mechanisms, such as a sliding mechanism composed of a guide rail and a slider. The discharge mechanism 5 also includes a pallet 5-5, which is arranged side by side with the discharge conveyor belt 5-1. The pallet 5-5 is driven to extend and retract by a third drive mechanism. In this embodiment, a pallet drive cylinder 5-3 is used. When the pallet 5-5 is driven to extend, it abuts against the tobacco leaves. Pallet 5-5 moves synchronously with the discharge conveyor belt. Figure 8 , 9 The diagram shows two pallet drive cylinders 5-3. The body of one of the pallet drive cylinders can be installed on the side of the discharge conveyor belt 5-1. When the conveyor belt drive cylinder 5-4 drives the discharge conveyor belt 5-1 to move, it will synchronously drive the pallet to move.

[0045] like Figure 12 , 13 As shown, the present invention also provides multiple scraping plates 5-6 on the discharge conveyor belt 5-1. The scraping plates are hand-shaped, and the openings are in the same direction of rotation as the discharge conveyor belt. Since the tobacco leaves may stick together, the scraping plates are used to separate the stuck tobacco leaves. The length of the scraping plates depends on the thickness of the stacked tobacco leaves that need to be separated. If more tobacco leaves need to be separated, the plates are set to be longer; if fewer tobacco leaves need to be separated, the plates are set to be shorter.

[0046] The following is combined with Figure 4 , 11 Explain the function of components such as the discharge conveyor belt and pallets. Figure 4 The tobacco leaf basket contains three rows of tobacco leaves, designated as the first, second, and third rows. The leaves are now being discharged sequentially from left to right. Moving the discharge conveyor belt 5-1 above the first row of leaves causes the pallet to move above the second and third rows. The pallet drive cylinder 5-3 actuates, causing the pallet to descend and press down on the second and third rows of leaves. Then, the tobacco basket rotating body 4 rotates to the discharge position, with the basket opening facing downwards. The discharge conveyor belt and pallet also rotate to the lower part of the basket rotating body. The first row of leaves falls onto the discharge conveyor belt, while the second and third rows are prevented from falling due to the pallet's obstruction. After the first row of leaves has been discharged, the tobacco basket rotating body rotates from the discharge position to... Figure 4The position is determined by the conveyor belt drive cylinder 5-4, which drives the discharge conveyor belt 5-1 and the pallet 5-5 to move to the right. The discharge conveyor belt moves to the top of the second row of tobacco leaves, and the pallet moves to the top of the third row of tobacco leaves. The pallet presses on the third row of tobacco leaves, and the tobacco basket rotates to the discharge position. At this time, the second row of tobacco leaves is discharged.

[0047] If the tobacco basket contains only one row of tobacco leaves, a sliding mechanism and a pallet are not required; simply place the tobacco basket in the corresponding position on the rotating body. For cases where the tobacco basket contains multiple rows of tobacco leaves, a sliding mechanism to move the discharge conveyor belt can be omitted. Instead, the tobacco basket is moved, placing the corresponding row of tobacco leaves below the discharge conveyor belt, while the other rows are placed below the pallet. However, this method does not have... Figure 4 The illustrated embodiments are convenient. Figure 4 The discharge mechanism 5 has a pallet set on one side of the discharge conveyor belt, or pallets can be set on both sides. In this way, the discharge can start from the second row of tobacco leaves, and the pallets on both sides press the first and third rows of tobacco leaves respectively.

[0048] like Figure 3 , 4 As shown in Figure 10, the pushing mechanism 6 is located at one end of the rotating tobacco basket body. The pushing mechanism 6 includes a lifting mechanism. Figure 10 The diagram shows a fork-shaped lifting mechanism 6-3, but a plate-shaped lifting mechanism can also be used. The fork-shaped lifting mechanism 6-3 is driven by a fourth drive mechanism for extension, retraction, and lifting. The fourth drive mechanism includes a telescopic drive mechanism and a lifting drive mechanism. Figure 10 The telescopic drive mechanism shown is telescopic cylinder 6-1, and the lifting drive mechanism is lifting cylinder 6-2. (Combined) Figure 4 , 11 When the tobacco basket rotates to the discharge position, one row of tobacco leaves falls down, creating a space between this row of leaves and the bottom plate of the tobacco basket. A telescopic cylinder drives a fork-shaped lifting mechanism 6-3 to extend into this space. Subsequently, a lifting cylinder 6-2 drives the fork-shaped lifting mechanism 6-3 to descend, pushing the tobacco leaves downwards. The descent speed of the fork-shaped lifting mechanism is adapted to the tobacco leaf discharge speed. Since there may be partial overlap between adjacent rows of tobacco leaves—that is, the tip of one row of leaves may pierce the base of another row—the fork-shaped lifting mechanism helps to push the tobacco leaves down.

[0049] The present invention also provides a tobacco leaf arranging system, including a tobacco leaf arranging machine, a conveying device, a power bed 3, and a feeding lifting roller conveyor 2 provided by the present invention.

[0050] like Figure 3 , 5As shown, the power bed 3 includes a bed support 3-1, corresponding to the two rotating rings on the tobacco basket rotating body 4. The bed support 3-1 is equipped with four rotating support wheels 3-3 and four longitudinal limiting wheels 3-4. Every two rotating support wheels and two longitudinal limiting wheels form a group, supporting one of the rotating rings. Driven by a motor, the rotating support wheels 3-3 drive the rotating rings to rotate, thereby driving the tobacco basket rotating body 4 to rotate. The longitudinal limiting wheels 3-4 are located on the lower sides of the tobacco basket rotating body 4, restricting its longitudinal movement. The power bed 3 is equipped with a lower rail 3-2 and an upper rail 3-5. The tobacco basket rotating body 4 and the bed support 3-1 can move longitudinally as a whole along the upper and lower rails (within a certain range). Figure 5 (From the perspective of the rotation axis of the tobacco basket rotating body). The power bed 3 has two main functions: first, to drive the longitudinal movement of the tobacco basket rotating body 4, with the direction of movement perpendicular to the central axis of the swing belt conveyor 1; second, to drive the tobacco basket rotating body 4 to rotate around its own axis.

[0051] like Figure 3 , 4 As shown, the conveying device is located at the bottom of the system, and the output device shown in the figure is a swing-handle belt conveyor 1. Figure 11 As shown, when the tobacco basket rotator 4 rotates to the discharge position, there is an angle α between the discharge conveyor belt 5-1 and the swing handle belt conveyor. The angle α is greater than 0° and less than 90°. The size of the angle can be determined according to the discharge speed. Since the tobacco basket 100 rotates synchronously with the discharge conveyor belt, if the angle is too large, the tobacco basket guardrail will be too flat, and the tobacco leaves will not easily fall out. If the angle is too small, the tobacco basket will rotate nearly 180° compared to the initial position, and the discharge speed will be very fast. The angle α can also be 0°, that is, the discharge conveyor belt 5-1 is parallel to the swing handle belt conveyor 1. At this time, the discharge speed is very fast, and a lot of tobacco leaves fall out onto the discharge conveyor belt at once.

[0052] As mentioned earlier when introducing the stacked conveyor, tobacco baskets typically contain multiple rows of tobacco leaves. The tobacco leaves can be discharged separately from each row by moving the conveyor mechanism or the tobacco basket. Since the tobacco leaves falling onto the conveyor mechanism need to be placed onto the conveying device, moving the conveyor mechanism will cause a misalignment between the two, preventing the tobacco leaves output by the conveyor mechanism from being placed onto the conveying device. The purpose of this invention is to move the tobacco basket rotating body 4 along the rotation axis of the tobacco basket rotating body via the power bed 3. This movement of the entire tobacco basket rotating body adjusts the positional relationship between the conveyor mechanism and the conveying device, ensuring they are aligned. This way, when the conveyor mechanism moves above the corresponding row of tobacco leaves, the alignment between the conveyor mechanism and the conveying device remains, ensuring that the tobacco leaves output by the conveyor mechanism are placed onto the conveying device. Obviously, it is also possible to move the conveying device instead of the power bed moving the tobacco basket rotating body.

[0053] like Figure 3 , 4 As shown, the present invention uses a feeding lifting roller conveyor 2 as a feeding device. The feeding lifting roller conveyor 2 is set at one end of the tobacco basket rotating body to send the tobacco basket into the tobacco basket rotating body.

[0054] The following details the swaying process of the tobacco leaf swaying system of the present invention.

[0055] 1. Initial position: Reference Figure 4 The feeding lifting roller conveyor 2 is in a high position, the tobacco basket rotating body 4 is in a 0° position, and the discharge mechanism is located above the tobacco basket rotating body 4. The support plate 4-3 on the tobacco basket rotating body 4 is in a retracted state, which does not affect the feeding of tobacco leaves into the tobacco basket rotating body. The conveyor belt drive cylinder 5-4 of the discharge mechanism 5 is in an extended state, so that the discharge conveyor belt 5-1 is positioned to the left side of the tobacco basket, that is, the discharge conveyor belt 5-1 is directly facing the first row of tobacco leaves. The pallet drive cylinder 5-3 of the discharge mechanism 5 is in a retracted state, and the pallet 5-5 is flush with the bottom surface of the discharge conveyor belt 5-1, that is, the pallet retracts back, which does not affect the feeding of tobacco leaves into the tobacco basket rotating body, and the swing belt conveyor 1 operates normally.

[0056] 2. The tobacco leaf baskets are transported to the feeding lifting roller conveyor 2 by logistics or forklift. The feeding lifting roller conveyor 2 operates to transport the tobacco leaf baskets into the tobacco basket rotating body 4. It is checked whether the tobacco leaf baskets are placed in place. The leaf base end of the first row of tobacco leaves in the tobacco leaf basket corresponding to this position is directly aligned with the right side plate 1-1 of the swing handle belt conveyor 1. The first row of tobacco leaves is located directly above the swing handle belt conveyor 1.

[0057] 3. The four synchronous telescopic cylinders 4-4 on the tobacco basket rotating body 4 extend, causing the support plate 4-3 to extend and abut against the tobacco basket guardrail, combined with... Figure 3 , 4 The support plate abuts against the left guardrail. The pallet drive cylinder 5-3 of the discharge mechanism 5 extends, and the pallet 5-5 extends downward to abut against the second and third rows of tobacco leaves.

[0058] 4. The tobacco basket rotating body 4 rotates counterclockwise 135° (this angle is adjusted within the range of (90-180)° according to the tobacco leaf discharge status, and this angle change results in a corresponding change in the included angle α), the tobacco basket rotating body 4 rotates to Figure 11 The discharge position is shown. The discharge conveyor belt 5-1 of the discharge mechanism 5 rotates clockwise to discharge the first row of tobacco leaves from the tobacco basket onto the swing belt conveyor 1.

[0059] 5. During the unloading process of the tobacco leaf basket, the tobacco leaves detach from the bottom plate of the tobacco leaf basket, creating a space between the tobacco leaves and the bottom plate of the tobacco leaf basket. The pushing mechanism 6 starts to work, and the telescopic cylinder 6-1 controls the fork-shaped lifting mechanism 6-3 to extend above the first row of tobacco leaves in the tobacco leaf basket. The lifting cylinder 6-2 drives the fork-shaped lifting mechanism 6-3 to descend, and the descent speed of the fork-shaped mechanism is adapted to the unloading speed of the tobacco leaves.

[0060] 6. After the first row of tobacco leaves in the tobacco basket is finished, the lifting cylinder 6-2 retracts, the fork-shaped lifting mechanism 6-3 rises to the initial position, the telescopic cylinder 6-1 retracts, and the fork-shaped lifting mechanism 6-3 is restored to the outer position of the tobacco basket. The tobacco basket rotating body 4 rotates counterclockwise by 45° so that the opening of the tobacco basket faces downward, and the first row of remaining tobacco leaves is finished.

[0061] 7. The tobacco basket rotating body 4 rotates 180° clockwise, the pallet drive cylinder 5-3 retracts, the pallet 5-5 returns to its initial position, the discharge conveyor belt 5-1 stops running, the conveyor belt drive cylinder 5-4 retracts, moving the discharge conveyor belt 5-1 to above the second row of tobacco leaves in the tobacco basket, the pallet drive cylinder 5-3 extends, and the pallet 5-5 presses down on the third row of tobacco leaves in the tobacco basket. Simultaneously with or at different times as the above actions, the power bed 3 moves along the upper track 3-5 and the lower track 3-2, driving the tobacco basket rotating body 4 and the tobacco basket as a whole to move until the leaf base of the second row of tobacco leaves is directly opposite the right side plate 1-1 of the swing belt conveyor 1, and the second row of tobacco leaves is located directly above the swing belt conveyor 1.

[0062] 8. The tobacco basket rotating body 4 rotates counterclockwise by 135°, and the discharge conveyor belt 5-1 of the discharge mechanism 5 rotates clockwise to discharge the second row of tobacco leaves to the swing handle belt conveyor 1.

[0063] 9. During the tobacco leaf unloading process, the tobacco leaves detach from the bottom plate of the tobacco leaf basket, creating a space between the tobacco leaves and the bottom plate of the tobacco leaf basket. The pushing mechanism 6 starts working, and the telescopic cylinder 6-1 controls the fork-shaped lifting mechanism 6-3 to extend above the second row of tobacco leaves in the tobacco leaf basket. The lifting cylinder 6-2 drives the fork-shaped lifting mechanism 6-3 to descend, and the descent speed of the fork-shaped mechanism is adapted to the tobacco leaf unloading speed.

[0064] 10. Repeat step 6 to finish placing the remaining tobacco leaves in the second row.

[0065] 11. Repeat the corresponding steps to output the third row of tobacco leaves.

[0066] 12. The automatic cigarette handle system returns to its initial position.
