Description

Technical Field

[0001] This invention relates to the technical field of tobacco leaf harvesting, storage, and initial processing, and in particular to a method for efficient and low-breakage unit transfer of tobacco bales. Background Technology

[0002] In existing technology, tobacco farmers deliver their first-cured tobacco leaves to tobacco stations (purchasing units), where they are packed into tobacco leaf containers (such as burlap sacks, plastic storage baskets, paper packaging boxes, etc.) to form basic tobacco bales. After a certain quantity is purchased, the tobacco bales are temporarily stacked and stored at the tobacco station. Then, the bales are unstacked and loaded onto trucks, where they are stacked again before being transported to the re-drying plant. At the re-drying plant, the bales are unstacked again during unloading, and each bale is individually packed into smaller stacks in tobacco frames. These stacks are then stored in the warehouse. During this process, the tobacco bales undergo at least two stacking and unstacking operations. The handling and throwing of the bales by loading and unloading personnel or equipment causes the internal tobacco leaves to break down – resulting in fragmentation. Tobacco leaves cannot be used for the production of medium- and high-grade cigarettes, thus reducing the amount of tobacco leaves available for high-grade cigarette production. This is a loss for both re-drying enterprises and cigarette manufacturers. Furthermore, the low efficiency of loading and unloading, coupled with high labor demands, especially during peak unloading periods at re-drying plants when manpower is scarce, creates difficulties for production management at re-drying plants and reduces revenue from transportation vehicles. Therefore, it is necessary to upgrade and transform the existing transshipment process of tobacco packaging units to reduce breakage and improve loading and unloading efficiency. This would ensure optimal resource utilization and value, while also improving the economic benefits for both re-drying and cigarette manufacturers. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a method for transferring tobacco package units with high efficiency and low breakage.

[0004] The technical solution of this invention is: a high-efficiency, low-breakage tobacco package unit transfer method comprising the following steps:

[0005] a. Establishment of tobacco packaging units

[0006] When tobacco purchasing units acquire tobacco leaves from tobacco farmers, they pack the leaves into tobacco leaf containers to form standard-sized tobacco bales filled with tobacco leaves. Before stacking the tobacco bales in the warehouse, a support frame is placed underneath each bale, and then the tobacco bales are stacked layer by layer on the support frame to form tobacco bale units, with N layers. The tobacco bales in adjacent layers are stacked in a staggered manner. This stacking method results in better overall stability of the tobacco bales units, which is beneficial for overall transportation.

[0007] b. Overall transfer of the tobacco package unit

[0008] Use handling equipment to lift the cigarette pack unit along with the supporting item to a suitable stacking plane, lower the supporting item to the stacking plane; then place the cigarette pack unit and the supporting item below it together on the stacking plane;

[0009] The stacking plane is the bottom surface of the entire stack;

[0010] c. First overall stacking

[0011] Repeat step b repeatedly to complete the transfer of each tobacco package unit and lay the tobacco package units flat to complete the first overall stacking; the first overall stacking is generally carried out at the tobacco station for temporary storage.

[0012] d. Depalletizing and stacking of trucks during loading

[0013] Next to the first overall stack, a handling device is used to transfer the cigarette pack unit along with the supporting object to achieve the first destacking; then the cigarette pack unit is lifted to a suitable truck stacking plane, and the supporting object is lowered onto the truck stacking plane; then the cigarette pack unit and the supporting object below it are placed on the truck stacking plane to complete the second stacking; the truck stacking plane is the bottom of the truck compartment, or the upper surface of a cigarette pack unit inside the truck compartment;

[0014] Repeat the first unstacking and second stacking actions repeatedly, and complete the second overall stacking inside the truck bed; the external shape of the first overall stack and the second overall stack are basically the same, the only difference is that the second stacking is a double-layer unit.

[0015] e. The truck transports the entire stack after the second stacking to the re-drying plant;

[0016] f. The cigarette pack unit is inserted into the cigarette frame.

[0017] Next to the open cargo compartment, a handling device is used to transfer the cigarette pack unit along with the load to achieve a second destacking; then the cigarette pack unit is lifted to the upper part of the appropriate bottom surface of the cigarette frame, and the load is lowered to the bottom surface of the cigarette frame; then the cigarette pack unit is put into the cigarette frame; the stacking plane of the cigarette frame is the bottom surface of the cigarette frame.

[0018] g. Repeat step f to load each tobacco pack unit into its corresponding tobacco frame.

[0019] Preferably, step a is repeated multiple times to establish multiple tobacco pack units.

[0020] Preferably, the arrangement of each layer of the tobacco pack unit includes four horizontally arranged tobacco packs forming a horizontal pack group and three vertically connected tobacco pack units forming a vertical pack group. The vertical pack groups are located side by side on the long side of the horizontal pack group. The ends of the horizontal pack group and the vertical pack group are aligned and the sides are attached to each other. Each layer is rectangular in shape. The vertical pack groups and horizontal pack groups of the upper and lower adjacent layers of the tobacco pack unit are stacked to form staggered stacking of tobacco pack units, which helps to ensure the overall stability of the tobacco pack unit.

[0021] Preferably, the unit size of the cigarette pack is 800mm*600mm*400mm, which is the most common standard size of a cigarette pack unit.

[0022] Preferably, the number of layers is 3 ≤ N ≤ 5.

[0023] Preferably, the supporting element is an isolation pad, which is a pad layer with a certain tensile strength, and the material is a thin metal plate, a thin plastic plate, or a thin rubber plate.

[0024] In step a, before stacking the cigarette packs in the warehouse, a layer of isolation mat is laid underneath, and then the cigarette packs are stacked layer by layer on the isolation mat to form a cigarette pack unit; after stacking, the part of the isolation mat that extends out of the cigarette pack unit is the clamping part; all cigarette pack units are covered with isolation mats.

[0025] In step b, a special shovel and pallet device is used to first clamp the clampable part of the isolation pad, slide the cigarette pack unit along with the isolation pad onto the pallet, then lift the cigarette pack unit above the appropriate stacking plane, lower the pallet to the stacking plane; then push the cigarette pack unit and the isolation pad below it together from the pallet onto the stacking plane to complete the placement; the cigarette pack unit and the isolation pad fall onto the stacking plane.

[0026] In step d, next to the first overall stack, a special shovel and support device is used to first clamp the clampable part of the isolation pad, and slide the cigarette pack unit along with the isolation pad onto the pallet to achieve the first destacking. Then, the cigarette pack unit is lifted to a suitable truck stacking plane, and the pallet is lowered onto the truck stacking plane. Finally, the cigarette pack unit and the isolation pad below it are pushed out of the pallet and placed onto the truck stacking plane to complete the second stacking.

[0027] In step f, next to the car body with the side panel open, a special shovel and support device is used to first clamp the clampable part of the isolation pad, and then slide the tobacco pack unit along with the isolation pad onto the support plate to achieve the second unstacking; then the tobacco pack unit is lifted to the upper part of the appropriate bottom surface of the tobacco frame, and the support plate is lowered to the bottom surface of the tobacco frame; then the tobacco pack unit is pushed out from the isolation pad into the tobacco frame to realize the installation of the tobacco pack unit into the tobacco frame.

[0028] Preferably, the efficient and low-breakage tobacco bale unit transfer method further includes step h: temporary storage of the tobacco bale units at the tobacco purchasing unit;

[0029] Steps b and c can be replaced by step h, which includes the following process:

[0030] h1 Set up storage shelves adapted to tobacco bale units in tobacco leaf purchasing units;

[0031] h2 uses handling equipment to transfer the cigarette pack unit along with the supporting item to the top of the appropriate storage shelf compartment, lowering the supporting item to the bottom of the storage shelf compartment; then the cigarette pack unit and the supporting item below it are placed into the storage shelf compartment.

[0032] h3 repeats step h2 until all storage compartments on the storage shelf are used or all cigarette pack units are delivered to the storage shelf.

[0033] In step h2, a special shovel-and-carry device is used to first clamp the clampable part of the isolation pad, slide the cigarette pack unit along with the isolation pad onto the pallet, then lift the cigarette pack unit above the appropriate storage compartment of the storage shelf, and lower the pallet to the bottom of the storage compartment of the storage shelf; then push the cigarette pack unit and the isolation pad below it together from the pallet into the storage compartment of the storage shelf; and finally push the cigarette pack unit and the isolation pad below it together from the pallet into the storage compartment of the storage shelf to complete the placement.

[0034] Preferably, the efficient and low-breakage tobacco bale unit transfer method further includes step i between steps e and f: establishing temporary storage for the tobacco bale units at the re-drying plant;

[0035] Step i. Temporary storage of tobacco packaging units at the re-drying plant.

[0036] A high-bay warehouse adapted to tobacco pack units is set up in the re-drying plant; next to the truck bed with the side panels open, the tobacco pack units are transferred as a whole along with the supporting items to achieve a second destacking using handling equipment; then the tobacco pack units are lifted to the top of a suitable high-bay warehouse storage compartment, and the supporting items are lowered to the bottom of the high-bay warehouse storage compartment; finally, the tobacco pack units and the supporting items below them are placed into the high-bay warehouse storage compartment.

[0037] In step i, a special shovel-and-pallet device is used to first clamp the clampable part of the isolation pad, and then slide the cigarette pack unit along with the isolation pad onto the pallet to achieve a second destacking. Then, the cigarette pack unit is lifted to the top of a suitable high-bay warehouse storage compartment, and the pallet is lowered to the bottom of the high-bay warehouse storage compartment. Then, the cigarette pack unit and the isolation pad below it are pushed out of the pallet into the high-bay warehouse storage compartment. Finally, the cigarette pack unit and the isolation pad below it are pushed out of the pallet into the storage compartment of the storage shelf to complete the placement.

[0038] Preferably, the pallet is a double-sided pallet with the forklift hole located in the middle of the side, so as to facilitate circulation and use.

[0039] In step a, before the cigarette pack units are stacked in the warehouse, a double-sided pallet is first set underneath them, and then the cigarette pack units are stacked layer by layer on the pallet to form a cigarette pack unit.

[0040] In step b, the fork of the fork is inserted into the forklift hole, and the forklift lifts the cigarette pack unit along with the double-sided pallet to a suitable stacking plane, and lowers the double-sided pallet to the stacking plane; then the cigarette pack unit and the double-sided pallet below it are placed together on the stacking plane to complete the placement.

[0041] In step d, next to the first overall stack, a forklift is used to transfer the cigarette pack unit along with the double-sided pallet to achieve the first destacking. Then, the cigarette pack unit is lifted above the appropriate truck stacking plane, and the double-sided pallet is lowered onto the truck stacking plane. Then, the cigarette pack unit and the double-sided pallet below it are placed on the truck stacking plane to complete the second stacking.

[0042] In step f, next to the truck bed with the side panel open, a forklift equipped with a rotary pusher is used to transfer the single unit of cigarette pack along with the double-sided pallet to achieve a second destacking. The rotary pusher is a special attachment for forklifts in the prior art, including a rotary disc, side clamps, top clamps, and fork teeth. The top clamps are positioned opposite the fork teeth, and the side clamps are positioned on one side of the fork teeth. During operation, the top and side clamps cooperate with the fork teeth to clamp the top and sides of the cigarette pack unit. The rotary disc drives the top and side clamps and fork teeth to rotate synchronously with the cigarette pack unit. The side clamps are mainly used to prevent the cigarette pack unit from falling during rotation. In this way, the double-sided pallet can change its position at the bottom of the cigarette pack unit, making it easier to remove. Then, the cigarette pack unit and the double-sided pallet are rotated vertically by 180° and then lifted to the upper part of the appropriate bottom surface of the cigarette frame, lowering the cigarette pack unit closer to the bottom surface of the cigarette frame. At this time, the top clamps should be as flush as possible with the bottom surface of the cigarette frame. Finally, the cigarette pack unit is loaded into the cigarette frame. The forklift leaves and the double-sided pallet is removed.

[0043] Preferably, tobacco leaf containers can be replaced with paper boxes or plastic storage baskets of the same shape and size.

[0044] Comparatively speaking, paper packaging boxes are more regular in shape than burlap sacks and plastic storage baskets, which is conducive to stacking; plastic storage baskets have ventilation holes on the bottom and sides, which provides better ventilation and can effectively prevent tobacco leaves from getting moldy; burlap sacks are the lowest cost circulation items.

[0045] The beneficial effects of the present invention are as follows: The efficient and low-breakage tobacco package unit transfer method of the present invention has the following advantages:

[0046] 1. By handling the tobacco bale units as a whole, the need to disassemble and stack individual tobacco bale units during the transfer process is reduced, avoiding the situation where tobacco bale units are moved around and thrown around. This reduces breakage, improves the effective utilization of tobacco leaves and the turnover efficiency of tobacco leaves, and increases the profits of tobacco companies.

[0047] 2. The handling of complete cigarette pack units can improve the logistics efficiency of cigarette pack unit transfer and save logistics time and labor costs.

[0048] 3. The tobacco pack unit consists of multiple layers of staggered stacked tobacco pack units. When transported as a whole using the isolation pad, it is not easy to fall apart, and the overall stability is high. The isolation pad is placed under the tobacco pack unit, and the tobacco pack unit can be transferred by pulling it out as a whole. It also facilitates the operation of the tobacco pack unit using a dedicated transfer tool, thereby improving the efficiency of the transfer.

[0049] 4. After being put into production, the isolation pads can be stacked and transported back to the tobacco station for reuse. The return can be done by special vehicles or logistics. The stacked pads take up little space and the transportation cost of the return is low. Attached Figure Description

[0066] Example 1: See Figure 1-8 A method for transferring a high-efficiency, low-breakage tobacco pack unit 3 includes the following steps:

[0067] a. Establishment of Tobacco Packaging Unit 3

[0068] When tobacco purchasing units purchase tobacco leaves from tobacco farmers, they pack the tobacco leaves into tobacco leaf containers to form standard-sized tobacco bales 1 filled with tobacco leaves. Before stacking tobacco bales 1 in the warehouse, a support is placed underneath each tobacco bale 1, and then the tobacco bales 1 are stacked layer by layer on the support to form tobacco bales unit 3, with N layers. The tobacco bales 1 in adjacent layers are stacked in a staggered manner. This stacking method results in better overall stability of tobacco bales 1, which is beneficial for overall transportation.

[0069] b. Overall transfer of tobacco package unit 3

[0070] Using handling equipment, lift the cigarette pack unit 3 along with the supporting item to a suitable stacking plane, lower the supporting item to the stacking plane, and then place the cigarette pack unit 3 and the supporting item below it together on the stacking plane;

[0071] The stacking plane is the bottom surface of the entire stack;

[0072] c. First overall stacking

[0073] Repeat step b repeatedly to complete the transfer of each tobacco package unit 3 and to lay the tobacco package unit 3 flat, thus completing the first overall stacking; the first overall stacking is generally carried out at the tobacco station for temporary storage.

[0074] d. Depalletizing and stacking of trucks during loading

[0075] Next to the first overall stack, the cigarette pack unit 3 is transferred along with the supporting object using handling equipment to achieve the first destacking; then the cigarette pack unit 3 is lifted to a suitable truck stacking plane 4, and the supporting object is lowered onto the truck stacking plane 4; then the cigarette pack unit 3 and the supporting object below it are placed on the truck stacking plane 4 to complete the second stacking; the truck stacking plane 4 is the bottom surface of the truck compartment, or the upper surface of a cigarette pack unit 3 inside the truck compartment;

[0076] Repeat the first unstacking and second stacking actions repeatedly, and complete the second overall stacking inside the truck bed; the external shape of the first overall stack and the second overall stack are basically the same, the only difference is that the second stacking is a double-layer unit.

[0077] e. The truck transports the entire stack after the second stacking to the re-drying plant;

[0078] f. Install the cigarette pack unit 3 into the cigarette frame.

[0079] Next to the open cargo compartment, the cigarette pack unit 3 is transferred along with the load to achieve a second unstacking using handling equipment; then the cigarette pack unit 3 is lifted to the upper part of the appropriate bottom surface of the cigarette frame, and the load is lowered to the bottom surface of the cigarette frame; then the cigarette pack unit 3 is installed into the cigarette frame; the stacking plane 5 of the cigarette frame is the bottom surface of the cigarette frame.

[0080] g. Repeat step f to insert each tobacco pack unit 3 into its respective tobacco frame.

[0081] Compared with the prior art, the present invention reduces the need for individual stacking and unpacking of tobacco bales 1 during the transportation process by handling the tobacco bale unit 3 as a whole, thus avoiding the situation where tobacco bale units 1 are moved around and thrown away. This reduces breakage, improves the effective utilization and turnover efficiency of tobacco leaves, and increases the profits of tobacco companies.

[0082] Step a is repeated multiple times to establish multiple cigarette pack units 3.

[0083] The arrangement of each layer of the tobacco pack unit 3 includes four horizontally arranged tobacco packs forming a horizontal pack group 31 and three vertically connected tobacco pack units 1 forming a vertical pack group 32. The vertical pack groups 32 are located side by side on the long side of the horizontal pack group 31. The ends of the horizontal pack group 31 and the vertical pack group 32 are aligned and the sides are attached to each other. Each layer is rectangular. The vertical pack groups 32 and the horizontal pack groups 31 of the upper and lower adjacent layers of the tobacco pack unit 3 are stacked to form staggered stacking of tobacco pack units 1, which helps to ensure the overall stability of the tobacco pack unit 3.

[0084] The dimensions of the tobacco pack unit 1 are 800mm*600mm*400mm, which is the most common standard size for tobacco pack unit 1. In this embodiment, the tobacco container is a burlap sack.

[0085] The number of layers is 3 ≤ N ≤ 5.

[0086] The number of layers N = 4.

[0087] The supporting component is the isolation pad 2, which is a pad with a certain tensile strength, and the material is a thin metal plate, a thin plastic plate, or a thin rubber plate.

[0088] In step a, before stacking the cigarette pack unit 1 in the warehouse, a layer of isolation mat 2 is laid underneath it, and then the cigarette pack units 1 are stacked layer by layer on the isolation mat 2 to form cigarette pack units 3; after stacking, the part of the edge of the isolation mat 2 extending out of the cigarette pack unit 3 is the clamping part 21; all cigarette pack units 3 are covered with isolation mat 2.

[0089] In step b, a special shovel and pallet device is used to first clamp the clampable part 21 of the isolation pad 2, slide the cigarette pack unit 3 along with the isolation pad 2 onto the pallet, then lift the cigarette pack unit 3 above a suitable stacking plane, lower the pallet to the stacking plane; then push the cigarette pack unit 3 and the isolation pad 2 below it together from the pallet to the stacking plane to complete the placement; the cigarette pack unit 3 and the isolation pad 2 fall on the stacking plane.

[0090] In step d, next to the first overall stack, a special shovel and support device is used to first clamp the clampable part 21 of the isolation pad 2, and slide the cigarette pack unit 3 along with the isolation pad 2 onto the pallet to achieve the first unstacking. Then, the cigarette pack unit 3 is lifted above the appropriate truck stacking plane 4, and the pallet is lowered onto the truck stacking plane 4. Then, the cigarette pack unit 3 and the isolation pad 2 below it are pushed out of the pallet and placed onto the truck stacking plane 4 to complete the placement and achieve the second stacking.

[0091] In step f, next to the car body with the side panel open, a special shovel and support device is used to first clamp the clampable part 21 of the isolation pad 2, and slide the tobacco pack unit 3 along with the isolation pad 2 onto the support plate to achieve the second stacking; then the tobacco pack unit 3 is lifted to the upper part of the appropriate bottom surface of the tobacco frame, and the support plate is lowered to the bottom surface of the tobacco frame; then the tobacco pack unit 3 is pushed out from the isolation pad 2 into the tobacco frame to realize the installation of the tobacco pack unit 3 into the tobacco frame.

[0092] Example 2: See Figure 9 Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that when the tobacco bale unit 3 established in step a exceeds the maximum storage capacity that can be achieved by laying out the tobacco bale unit 3 in the tobacco purchasing unit warehouse, in order to improve the space utilization rate of the tobacco purchasing unit warehouse, a storage shelf 6 adapted to the tobacco bale unit 3 is set up in the tobacco purchasing unit.

[0093] The efficient and low-breakage tobacco bale unit 3 transfer method also includes step h: temporary storage of the tobacco bale unit 3 at the tobacco purchasing unit;

[0094] Steps b and c can be replaced by step h, which includes the following process:

[0095] h1 Set up storage shelves 6 adapted to tobacco bale units 3 in tobacco leaf purchasing units;

[0096] h2 uses handling equipment to transfer the cigarette pack unit 3 along with the supporting item to the upper part of the appropriate storage shelf 6 storage compartment, lowering the supporting item to the bottom of the storage shelf 6 storage compartment; then the cigarette pack unit 3 and the supporting item below it are placed into the storage shelf 6 storage compartment;

[0097] h3 repeats step h2 until all storage compartments of storage shelf 6 are used or all cigarette pack units 3 are delivered to storage shelf 6.

[0098] In this embodiment, in step h2, a special shovel-and-carry device is used to first clamp the clampable part 21 of the isolation pad 2, slide the cigarette pack unit 3 along with the isolation pad 2 onto the tray, then lift the cigarette pack unit 3 above the appropriate storage compartment of the storage shelf 6, and lower the tray to the bottom of the storage compartment of the storage shelf 6; then push the cigarette pack unit 3 and the isolation pad 2 below it together from the tray into the storage compartment of the storage shelf 6; and finally push the cigarette pack unit 3 and the isolation pad 2 below it together from the tray into the storage compartment of the storage shelf 6 to complete the placement.

[0099] Example 3: See Figure 10 Example 3 is basically the same as Example 1, and the similarities will not be repeated. The differences are as follows:

[0100] When the number of tobacco package units 3 received by the re-drying plant exceeds the maximum number of tobacco package units 3 that can be loaded using tobacco frames inside the re-drying plant, the re-drying plant is equipped with an elevated warehouse 7 that is adapted to the tobacco package units 3.

[0101] The efficient and low-breakage tobacco bale unit 3 transfer method also includes step i between steps e and f: establishing a temporary storage for the tobacco bale unit 3 at the re-drying plant;

[0102] Step i. Temporary storage of tobacco packages in re-drying plant, unit 3.

[0103] A high-bay warehouse 7 adapted to the tobacco pack unit 3 is set up in the re-drying plant; next to the truck bed with the side panel open, the tobacco pack unit 3 is transferred as a whole along with the supporting items to achieve a second destacking using handling equipment; then the tobacco pack unit 3 is lifted to the top of a suitable storage compartment in the high-bay warehouse 7, and the supporting items are lowered to the bottom of the storage compartment in the high-bay warehouse 7; then the tobacco pack unit 3 and the supporting items below it are placed in the storage compartment in the high-bay warehouse 7.

[0104] In this embodiment, in step i, a special shovel and pallet device is used to first clamp the clampable part 21 of the isolation pad 2, and slide the cigarette pack unit 3 along with the isolation pad 2 onto the pallet to achieve the second destacking. Then, the cigarette pack unit 3 is lifted to the top of the appropriate storage compartment of the high-rise warehouse 7, and the pallet is lowered to the bottom of the storage compartment of the high-rise warehouse 7. Then, the cigarette pack unit 3 and the isolation pad 2 below it are pushed out of the pallet into the storage compartment of the high-rise warehouse 7. Finally, the cigarette pack unit 3 and the isolation pad 2 below it are pushed out of the pallet into the storage compartment of the storage shelf 6 to complete the placement.

[0105] Example 4: See Figure 11 Example 4 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the supporting component is a double-sided pallet with the forklift hole located in the middle of the side, so as to facilitate circulation and use.

[0106] In step a, before the cigarette pack unit 1 is stacked in the warehouse, a double-sided pallet is first set underneath it, and then the cigarette pack unit 1 is stacked layer by layer on the pallet to form cigarette pack unit 3;

[0107] In step b, the fork of the fork is inserted into the forklift hole, and the forklift lifts the cigarette pack unit 3 along with the double-sided pallet to a suitable stacking plane, and lowers the double-sided pallet to the stacking plane; then the cigarette pack unit 3 and the double-sided pallet below it are placed together on the stacking plane to complete the placement.

[0108] In step d, next to the first overall stack, a forklift is used to transfer the cigarette pack unit 3 along with the double-sided pallet to achieve the first destacking. Then, the cigarette pack unit 3 is lifted above the appropriate truck stacking plane 4, and the double-sided pallet is lowered onto the truck stacking plane 4. Then, the cigarette pack unit 3 and the double-sided pallet below it are placed on the truck stacking plane 4 to complete the second stacking.

[0109] In step f, next to the truck bed with the side panel open, a forklift equipped with a rotary pusher is used to transfer the single unit of cigarette pack along with the double-sided pallet to achieve a second destacking. The rotary pusher is a special attachment for forklifts in the prior art, including a rotary disc, side clamps, a top clamp, and fork teeth. The top clamp is positioned on the opposite side of the fork teeth; the side clamp is positioned on one side of the fork teeth. During operation, the top clamp, side clamp, and fork teeth cooperate to clamp the top and side surfaces of the cigarette pack unit 3. The rotary disc drives the top clamp, side clamp, and fork teeth to clamp the top and side surfaces of the cigarette pack unit 3. The fork tines rotate synchronously with the cigarette pack unit 3; the side clamps are mainly used to prevent the cigarette pack unit 3 from falling during rotation; in this way, the double-sided pallet can change the position at the bottom of the cigarette pack unit 3, making it easier to remove; then the cigarette pack unit 3 and the double-sided pallet are rotated vertically 180° and then lifted to the upper part of the appropriate bottom surface of the cigarette frame, lowering the cigarette pack unit 3 closer to the bottom surface of the cigarette frame; at this time, the top clamp should be as flush as possible with the bottom surface of the cigarette frame; finally, the cigarette pack unit 3 is installed into the cigarette frame; the forklift leaves and the double-sided pallet is removed.

[0110] Example 5: See Figure 12-13 Example 5 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the tobacco container can be replaced by a paper packaging box or plastic storage basket of the same shape and size.

[0111] Comparatively speaking, paper packaging boxes are more regular in shape than burlap sacks and plastic storage baskets, which is conducive to stacking; plastic storage baskets have ventilation holes on the bottom and sides, which provides better ventilation and can effectively prevent tobacco leaves from getting moldy; burlap sacks are the lowest cost circulation items.
