Description

Technical Field

[0001] The present application relates to the technical field of tobacco sorting and packaging, and in particular to a cigarette packing production line. Background Art

[0002] In the tobacco industry, cigarette cartons are typically packaged in plastic film. However, plastic film takes a long time to degrade and can cause environmental pollution. Therefore, to reduce plastic pollution, woven bags can be used instead of plastic film to package cigarette cartons.

[0003] Due to factors such as market demand and packaging efficiency, woven bags cannot completely replace plastic film. Therefore, there is market demand for both plastic film-wrapped and woven bag-wrapped cigarette cartons. However, current cigarette carton packaging production lines only have equipment for plastic film packaging, resulting in limited packaging flexibility and difficulty in adapting to market demand.

[0045] The embodiment of the present application provides a cigarette carton packaging production line, which is used to solve the technical problem that the packaging method of the cigarette carton packaging production line has poor flexibility.

[0046] In the embodiments of this application, Figure 1 As shown, the cigarette packaging production line includes a first conveying mechanism 1, a film wrapping device 2, a heat shrinking device 3, and a bagging device 4. The first conveying mechanism 1 is used to convey a first pallet 80. The film wrapping device 2 and the bagging device 4 are both connected to the side of the first conveying mechanism 1, and the heat shrinking device 3 is connected to the film wrapping device 2.

[0047] In this embodiment, a first conveying mechanism 1 is used to convey a first tray 80, which is used to hold cigarette cartons. A film wrapping device 2 is used to wrap the cigarette cartons with plastic film. A heat shrinking device 3 is used to heat the wrapped cigarette cartons, causing the plastic film to shrink and adhere tightly to the surface of the cigarette cartons. A bagging device 4 is used to pack the cigarette cartons into woven bags.

[0048] The first conveying mechanism 1 of the embodiment of the present application is used to convey the portion of the first tray 80 on which the cigarettes are placed to the docking position between the film wrapping device 2 and the first conveying mechanism 1, so that the cigarettes in the portion of the first tray 80 can be received by the film wrapping device 2, and the received cigarettes can be wrapped with plastic film; after the film wrapping device 2 completes wrapping the cigarettes, the cigarettes wrapped with plastic film are conveyed to the heat shrinking device 3, so that the cigarettes wrapped with plastic film are heated by the heat shrinking device 3, so that the plastic film is tightly attached to the cigarettes, and the packaging of the cigarettes is completed; the first conveying mechanism 1 conveys the remaining first tray 80 on which the cigarettes are placed to the docking position between the bagging device 4 and the first conveying mechanism 1, so that the cigarettes in the portion of the first tray 80 can be received by the bagging device 4, and the received cigarettes are put into woven bags to realize bagging of the cigarettes; since the cigarettes can be selectively packaged in woven bags and plastic films according to actual needs, the flexibility of the cigarette packaging method can be improved to adapt to market demand.

[0049] In one embodiment, if Figure 1 and Figure 2 As shown, the cigarette packaging production line further includes a first lifting device 5 and a second lifting device 6. The first lifting device 5 is disposed at the end of the first conveying mechanism 1 in the loading direction. The second lifting device 6 is disposed at the end of the first conveying mechanism 1 away from the first lifting device 5. The first conveying mechanism 1 includes a first conveying layer 11 and a second conveying layer 12. The second conveying layer 12 is located directly below the first conveying layer 11. The conveying direction of the first conveying layer 11 is opposite to that of the second conveying layer 12.

[0050] In this embodiment, the first conveying layer 11 can convey the first tray 80 with cigarettes placed thereon, and the second conveying layer 12 can convey the empty first tray 80 .

[0051] When the first conveying layer 11 conveys the first tray 80 with cigarettes placed thereon and the second conveying layer 12 conveys the empty first tray 80:

[0052] The first conveying layer 11 transports the first tray 80 containing cigarette cartons to the wrapping device 2 or the bagging device 4, where the cigarette cartons in the first tray 80 are wrapped and then transported to the heat shrinking device 3. Alternatively, the bagging device 4 places the cigarette cartons in the first tray 80 into woven bags. At this point, the cigarette cartons are separated from the first tray 80, and the first conveying layer 11 continues to transport the empty first tray 80 until it reaches the first lifting device 5. The first lifting device 5 then transports the empty first tray 80 downward to the second conveying layer 12. From there, the empty first tray 80 is transported from the first lifting device 5 to the second lifting device 6. The second lifting device 6 then lifts the empty first tray 80 from the second conveying layer 12 back to the first conveying layer 11, allowing cigarette cartons to be placed in the lifted empty first tray 80, thus achieving recycling of the first tray 80.

[0053] In one embodiment, if Figure 1 As shown, the cigarette packaging production line further includes a second conveying mechanism 7 and a loading device 8. The second conveying mechanism 7 is used to convey a second tray 90. The bagging device 4 is docked with the second conveying mechanism 7, and the loading device 8 is docked with the second conveying mechanism 7. Among them, the second tray 90 is used to place woven bags.

[0054] The loading device 8 is used to place the woven bags on the second tray 90 on the second conveying mechanism 7, so that the second tray 90 with the woven bags is transported to the docking position between the bagging device 4 and the second conveying mechanism 7 through the second conveying mechanism 7. Then, the cigarette cartons are loaded into the woven bags by the bagging device 4, thereby realizing the bagging of the cigarette cartons and improving the bagging efficiency of the cigarette cartons.

[0055] In one embodiment, if Figure 1 As shown, the film wrapping device 2 and the heat shrinking device 3 are sequentially arranged along a conveying direction perpendicular to the first conveying mechanism 1. This can prevent the heat shrinking device 3 from interfering with the bagging device 4 or the second conveying mechanism 7, making the location of the heat shrinking device 3 more reasonable, thereby improving the rationality of the layout of the cigarette packaging production line.

[0056] In one embodiment, if Figure 1 As shown, the cigarette packaging production line also includes a third conveying mechanism 9, the end of which is connected to the heat shrinking device 3, and the conveying direction of the end of the third conveying mechanism 9 away from the heat shrinking device 3, the conveying direction of the second conveying mechanism 7 and the conveying direction of the first conveying mechanism 1 are all parallel to each other.

[0057] The heat shrink device 3 heats the wrapped cigarettes so that the plastic film is tightly attached to the cigarettes. After the plastic film packaging is completed, the finished product is conveyed to the third conveying mechanism 9 for unloading through the third conveying mechanism 9. The provision of the third conveying mechanism 9 can improve the flexibility of the unloading position.

[0058] The conveying direction of the end of the third conveying mechanism 9 away from the heat shrinkage device 3, the conveying direction of the second conveying mechanism 7 and the conveying direction of the first conveying mechanism 1 are parallel to each other, so that the layout of the first conveying mechanism 1, the second conveying mechanism 7 and the third conveying mechanism 9 is more reasonable, and the effective total area occupied by the first conveying mechanism 1, the second conveying mechanism 7 and the third conveying mechanism 9 is reduced.

[0059] In one embodiment, if Figure 1 As shown, the second conveying mechanism 7 is located between the first conveying mechanism 1 and the third conveying mechanism 9. This improves the rationality of the placement of the second conveying mechanism 7 and further reduces the total effective area occupied by the first conveying mechanism 1, the second conveying mechanism 7, and the third conveying mechanism 9. It also prevents interference between the second conveying mechanism 7 and the first conveying mechanism 1 or the third conveying mechanism 9.

[0060] In one embodiment, if Figure 1 As shown, the film wrapping device 2 and the bagging device 4 are arranged sequentially along the conveying direction of the first conveying mechanism 1. The heat shrinking device 3 is longer than the bagging device 4, thereby preventing interference between the heat shrinking device 3, the second conveying mechanism 7, and the bagging device 4, thereby improving the rationality of the installation position of the film wrapping device 2 and the bagging device 4.

[0061] In one embodiment, if Figure 1 As shown, the cigarette packaging production line also includes a fifth conveying mechanism 70, the end of which is connected to the bagging device 4, so that the bagged cigarettes are transported to a preset position for unloading through the fifth conveying mechanism 70, thereby improving the flexibility of unloading and bagging the cigarettes.

[0062] In this embodiment, the conveying direction of the fifth conveying mechanism 70 is parallel to the conveying direction of the second conveying mechanism 7 , and the fifth conveying mechanism 70 is located between the first conveying mechanism 1 and the second conveying mechanism 7 .

[0063] In one embodiment, if Figure 1 As shown, the cigarette packaging production line further includes a third lifting device 10 and a fourth lifting device 20. The third lifting device 10 is disposed at the end of the second conveying mechanism 7 in the loading direction. The fourth lifting device 20 is disposed at the end of the second conveying mechanism 7 away from the third lifting device 10. The second conveying mechanism 7 includes a third conveying layer and a fourth conveying layer. The fourth conveying layer is located directly below the third conveying layer, and the conveying direction of the third conveying layer is opposite to that of the fourth conveying layer.

[0064] In this embodiment, the third conveying layer can convey the second pallet 90 with the woven bags placed thereon, and the fourth conveying layer can convey the empty second pallet 90 .

[0065] When the second pallet 90 with woven bags is transported on the third transport layer and the empty second pallet 90 is transported on the fourth transport layer:

[0066] After the loading device 8 places the woven bag into the second tray 90 on the third conveyor layer, the third conveyor layer transports the second tray 90 with the woven bag to the docking position between the bagging device 4 and the third conveyor layer, where the cigarettes are loaded into the woven bag. At this time, the woven bag is separated from the second tray 90. After being separated from the woven bag, the empty second tray 90 is further transported by the third conveyor layer to the third lifting device 10, which then transports the empty second tray 90 from the third conveyor layer downward to the fourth conveyor layer. The fourth conveyor layer then transports the empty second tray 90 to the fourth lifting device 20, which then lifts the empty second tray 90 to the third conveyor layer. The empty second tray 90 is then transported by the third conveyor layer to the docking position between the loading device 8 and the third conveyor layer, where the loading device 8 places the woven bag into the empty second tray 90. This allows the second tray 90 to be recycled.

[0067] Specifically, the structure of the second conveying mechanism 7 can refer to the first conveying mechanism 1 , and the structures of the second lifting device 6 , the third lifting device 10 and the fourth lifting device 20 can refer to the first lifting device 5 , which will not be repeated in this embodiment.

[0068] In one embodiment, if Figure 1 As shown, the cigarette packing production line further includes a fourth conveying mechanism 30 and a cigarette stacking device 40. The fourth conveying mechanism 30 is used to convey cigarettes. The cigarette stacking device 40 is connected to the end of the fourth conveying mechanism 30 in the conveying direction. The first conveying mechanism 1 is connected to the cigarette stacking device 40.

[0069] The stacking device 40 is used to receive the cigarettes conveyed by the fourth conveying mechanism 30 and stack the received cigarettes in the first tray 80 according to the actual required quantity so that the stacked cigarettes can be subsequently wrapped with plastic film or placed in woven bags. The stacking device 40 can stack the cigarettes in the first tray 80 in a single layer or multiple layers.

[0070] In one embodiment, if Figure 1 As shown, multiple fourth conveying mechanisms 30 and multiple cigarette stacking devices 40 are provided, and the fourth conveying mechanisms 30 and the cigarette stacking devices 40 are provided one-to-one. This can improve the efficiency of stacking cigarette cartons in the first tray 80, and can also transport cigarette cartons of different specifications through the fourth conveying mechanism 30, thereby improving the applicability of the cigarette packaging production line.

[0071] In one embodiment, if Figure 1 As shown, the conveying direction of the fourth conveying mechanism 30 is parallel to the conveying direction of the first conveying mechanism 1 .

[0072] In one embodiment, if Figure 1 As shown, the cigarette packaging production line also includes a first pushing device 50, which is connected to the first conveying mechanism 1. The first pushing device 50 and the film wrapping device 2 are respectively arranged on opposite sides of the first conveying mechanism 1, and the output end of the first pushing device 50 can be close to or away from the film wrapping device 2 above the first conveying mechanism 1.

[0073] When the first conveying mechanism 1 conveys the first tray 80 with the cigarettes to the docking position between the first pushing device 50 and the first conveying mechanism 1, the output end of the first pushing device 50 can push the cigarettes in the first tray 80 into the wrapping device 2 so that the wrapping device 2 can wrap the cigarettes.

[0074] Specifically, the specific structure of the first pushing device 50 can refer to the second pushing device 60, and will not be repeated in this embodiment.

[0075] In one embodiment, the first pushing device 50 includes a first support frame, a first drive unit, and a first push plate. The first support frame and the film wrapping device 2 are respectively disposed on opposite sides of the first conveying mechanism 1. The first drive unit is disposed on the first support frame, and the first push plate is disposed at the output end of the first drive unit. The first drive unit can drive the first push plate to move toward or away from the film wrapping device 2 above the first conveying mechanism 1, thereby pushing the cigarette cartons in the first tray 80 into the film wrapping device 2 via the first push plate.

[0076] In one embodiment, if Figure 1 As shown, the cigarette packaging production line also includes a second pushing device 60, which is connected to the first conveying mechanism 1. The second pushing device 60 and the bagging device 4 are respectively arranged on opposite sides of the first conveying mechanism 1. The output end of the second pushing device 60 can be close to or away from the bagging device 4 above the first conveying mechanism 1.

[0077] In one embodiment, if Figure 1 and Figure 3 As shown, the second pushing device 60 includes a second support frame 601, a second drive unit 602, and a second push plate 603. The second support frame 601 and the bagging device 4 are respectively arranged on opposite sides of the first conveying mechanism 1. The second drive unit 602 is arranged on the second support frame 601, and the second push plate 603 is arranged at the output end of the second drive unit 602. The second drive unit 602 can drive the second push plate 603 to move toward or away from the bagging device 4 above the first conveying mechanism 1, so that the second push plate 603 can push the cigarette cartons in the first tray 80 into the bagging device 4.

[0078] In one embodiment, the cigarette stacking device 40 includes a third support frame, a third drive unit, a receiving platform, an adapter assembly and a horizontal push assembly, and the third drive unit is arranged on the third support frame. The receiving platform is arranged at the output end of the third drive unit, and the third drive unit is used to drive the receiving platform to rise and fall. The adapter assembly is arranged on the third support frame, and the adapter assembly is located above the receiving platform. The adapter assembly is used to place the cigarette strips received from the fourth conveying mechanism 30 on the receiving platform. The horizontal push assembly is arranged on the receiving platform, and the pushing end of the horizontal push assembly is located above the receiving platform. The pushing end of the horizontal push assembly can be close to or away from the first conveying mechanism 1.

[0079] After the adapter assembly receives the cigarette strips from the fourth conveying mechanism 30, the third drive unit drives the receiving platform to rise and fall to a suitable height so that the adapter assembly can place the received cigarette strips on the receiving platform. After multiple cooperation between the adapter assembly and the receiving platform, the cigarette strips can be stacked on the receiving platform. The third drive unit then drives the receiving platform to rise and fall to a position with the same height as the first tray 80 on the first conveying mechanism 1. The pushing end of the horizontal push assembly then pushes the cigarette strips stacked on the receiving platform into the first tray 80. After the horizontal push assembly pushes the cigarette strips to the first tray 80, the pushing end of the horizontal push assembly moves in a direction away from the first conveying mechanism 1 so that the adapter assembly can place the cigarette strips received from the fourth conveying mechanism 30 on the receiving platform.

[0080] In one embodiment, the adapter assembly includes a conveying member, a receiving member, and two rotating members. The rotating members are rotatably mounted on a third support frame and spaced apart in a vertical direction. The conveying member is tensioned against the two rotating members, and the rotating members are configured to drive the conveying member to rotate about the rotating members. The receiving member is disposed on the outer surface of the conveying member, with its length perpendicular to the outer surface of the conveying member. The receiving member may be a plate-like structure, and the conveying member may be a belt-like structure.

[0081] It can be understood that the shape of the rotation trajectory of the conveying member is an oblong. When the receiving member moves to a position between the two rotating members and close to the top, the length direction of the receiving member is parallel to and at the same height as the conveying plane of the fourth conveying mechanism 30, so the cigarette strips can be conveyed to the receiving member. The conveying member then drives the receiving member to move downward until the receiving member passes over the rotating member below. In the process of moving to the other side of the rotating member, the end of the receiving member will gradually tilt. At this time, the cigarette strips on the receiving member will slide down from the receiving member under the action of their own gravity and fall onto the receiving platform. When the distance between the receiving platform and the receiving member is reasonable, the cigarette strips can stably fall from the receiving member to the receiving platform.

[0082] In one embodiment, a plurality of receiving members are arranged at intervals on the conveying member.

[0083] In one embodiment, two adapter assemblies are provided, and the two adapter assemblies are symmetrically arranged about a vertical plane in the conveying direction of the fourth conveying mechanism 30. The receiving members of the two adapter assemblies are spaced apart and arranged at the same height, so that the receiving members of the two adapter assemblies can receive and convey cigarette cartons from the fourth conveying mechanism 30 together, thereby improving the stability of the receiving members in conveying cigarette cartons.

[0084] In another alternative embodiment, the stacking device 40 includes a fourth support frame, a fourth drive unit, and a flip member, with the fourth drive unit being mounted on the fourth support frame. The flip member is rotatably mounted on the fourth support frame and connected to the output end of the fourth drive unit. The fourth drive unit is configured to rotate the flip member so that its receiving surface is flush with the conveying plane of the fourth conveying mechanism 30, or parallel to the vertical direction. The first conveying mechanism 1 is located directly below the flip member.

[0085] The fourth drive unit rotates the flip member until its receiving surface is flush with the conveying plane of the fourth conveying mechanism 30. The fourth conveying mechanism 30 then pushes at least one cigarette carton onto the receiving surface of the flip member. The fourth drive unit then rotates the flip member again, aligning the receiving surface with the vertical direction. During this process, the cigarette carton falls from the flip member under its own weight into the first tray 80 below it, completing the loading of the cigarette carton into the first tray 80. The flip member may be a plate-like structure.

[0086] In one embodiment, the film wrapping device 2 includes a fifth support frame, a conveying platform, a fifth drive unit, a pressure plate, a sixth drive unit, a film cutting unit, a film stretching unit and a tensioning roller. The conveying platform, the fifth drive unit, the sixth drive unit, the film stretching unit and the tensioning roller are all arranged on the fifth support frame, and the conveying platform is connected to the first conveying mechanism 1. The pressure plate is arranged at the output end of the fifth drive unit, and the pressure plate is located directly above the conveying platform. The fifth drive unit is used to drive the pressure plate to move closer to or away from the conveying platform. The film cutting unit is arranged at the output end of the sixth drive unit, and the sixth drive unit is used to drive the film cutting unit to move up and down. The height of the film stretching unit is not higher than the height of the conveying platform, and the film stretching unit, the film cutting unit and the pressure plate are arranged in sequence along the conveying direction of the conveying platform. The tensioning roller is located above the film stretching unit.

[0087] The film-stretching unit is used to pull the plastic film down from the tensioning roller so that the plastic film spans the tensioning roller and the film-stretching unit. Since the height of the film-stretching unit is not higher than the height of the conveying platform, and the tensioning roller is located above the film-stretching unit, the film-stretching unit, the film-cutting unit and the pressure plate are arranged in sequence along the conveying direction of the conveying platform. Therefore, in the process of pushing the cigarettes in the first tray 80 toward the conveying platform, the end of the cigarette away from its stressed end will press against the plastic film and drag the plastic film from the tensioning roller until the cigarette is pushed to the corresponding position of the conveying platform. At this time, the plastic film between the film-stretching unit and the tensioning roller will be tensioned on the end of the cigarette away from its stressed end.

[0088] The fifth drive unit then drives the pressure plate toward the conveyor platform, pressing the plastic film above the cigarette rods onto them. The sixth drive unit then drives the film cutting unit downward, severing the plastic film and wrapping the cigarette rods. Finally, the conveyor platform delivers the wrapped cigarette rods to the heat shrink unit 3.

[0089] It can be understood that the film cutting unit cuts the plastic film above the cigarettes, and can also fix the cut end of the plastic film stretched on the tensioning roller to the film stretching unit so as to wrap the cigarettes in the next first tray 80 with film.

[0090] In one embodiment, if Figure 1 and Figure 3 As shown, the bagging device 4 includes a sixth support frame 41, a seventh drive unit 42, a first support plate 43, an eighth drive unit 44, a second support plate 45, a ninth drive unit 46, a suction cup assembly 47, and a tenth drive unit 48. The seventh drive unit 42 is arranged on the sixth support frame 41, the first support plate 43 is arranged at the output end of the seventh drive unit 42, and the seventh drive unit 42 is used to drive the first support plate 43 to move up and down. The eighth drive unit 44 is arranged on the sixth support frame 41, the second support plate 45 is arranged at the output end of the eighth drive unit 44, and the eighth drive unit 44 is used to drive the second support plate 45 to move up and down. The second support plate 45 is located directly below the first support plate 43, and the lifting trajectory of the second support plate 45 is located on the side of the first conveying mechanism 1. The ninth drive unit 46 is slidably arranged on the sixth support frame 41, the suction cup assembly 47 is arranged at the output end of the ninth drive unit 46, and the ninth drive unit 46 is used to drive the suction cup assembly 47 to move up and down. The tenth driving unit 48 is arranged on the sixth support frame 41, and the ninth driving unit 46 is connected to the output end of the tenth driving unit 48. The tenth driving unit 48 is used to drive the ninth driving unit 46 to slide on the sixth support frame 41 so that the suction cup assembly 47 is close to or away from the first support plate 43.

[0091] The tenth driving unit 48 can drive the ninth driving unit 46 to slide on the sixth supporting frame 41 to indirectly drive the suction cup assembly 47 to the top of the woven bag. Then the ninth driving unit 46 drives the suction cup assembly 47 to descend to absorb and grab the woven bag through the suction cup assembly 47.

[0092] The eighth driving unit 44 can drive the second support plate 45 to move toward the first support plate 43 to adjust the distance between the second support plate 45 and the first support plate 43 to facilitate the first support plate 43 and the second support plate 45 to extend into the woven bag together.

[0093] The ninth drive unit 46 then drives the suction cup assembly 47 up and down to adjust the height of the woven bag held by the suction cup assembly 47 so that the height of the woven bag corresponds to the height of the first support plate 43 and the second support plate 45. The tenth drive unit 48 then drives the ninth drive unit 46 toward the first support plate 43 and the second support plate 45. Because the spacing between the first support plate 43 and the second support plate 45 and the height of the woven bag held by the suction cup assembly 47 have already been adjusted accordingly, the first support plate 43 and the second support plate 45 will extend into the woven bag as the tenth drive unit 48 drives the ninth drive unit 46 toward the first support plate 43 and the second support plate 45.

[0094] After the first and second support plates 43, 45 extend into the woven bag, the suction cup assembly 47 releases the woven bag. The tenth drive unit 48 then drives the ninth drive unit 46 to move away from the first and second support plates 43, 45. The eighth drive unit 44 then drives the second support plate 45 to move away from the first support plate 43, thereby increasing the distance between the second and first support plates 45, 43, and thereby expanding the woven bag through the second and first support plates 45, 43. Thereafter, the seventh drive unit 42 drives the first support plate 43 downward, and the eighth drive unit 44 drives the second support plate 45 downward, allowing the first and second support plates 43, 45 to move downward synchronously. When the opening of the woven bag, opened by the first and second support plates 43, 45, faces the cigarettes in the first tray 80 being conveyed by the first conveyor mechanism 1, the seventh drive unit 42 stops driving the first support plate 43 downward, and the eighth drive unit 44 stops driving the second support plate 45 downward.

[0095] When the opening of the woven bag, which is opened by the first support plate 43 and the second support plate 45, is aligned with the cigarette cartons in the first tray 80, the cigarette cartons can be manually pushed from the first tray 80 into the woven bag to achieve bagging. Alternatively, the second pushing device 60 can be used to push the cigarette cartons in the first tray 80 into the woven bag to achieve bagging.

[0096] In one embodiment, if Figure 1 and Figure 4As shown, the first lifting device 5 includes a seventh support frame 51, an eleventh drive unit 52, a lifting member 53, a carrier 54, a roller 55, and a twelfth drive unit. The eleventh drive unit 52 is mounted on the seventh support frame 51. The lifting member 53 is mounted at the output end of the eleventh drive unit 52 and is used to drive the lifting member 53 to rotate. The lifting member 53 has an oblong rotational trajectory; the rotational trajectories on opposite sides of the lifting member 53 are parallel, rotate in opposite directions, and are parallel to the vertical direction. The carrier 54 is mounted on the outside of the lifting member 53, with its length perpendicular to the vertical direction. The roller 55 is rotatably mounted on the carrier 54, with its rotational centerline perpendicular to the vertical direction and the length of the carrier 54. The roller 55 can be docked with the first conveying mechanism 1 or the third conveying mechanism 9. The twelfth drive unit is mounted on the carrier 54 and connected to the output end of the twelfth drive unit and is used to drive the roller 55 to rotate.

[0097] The lifting member 53 may be a belt-shaped structure or a chain-shaped structure.

[0098] The first conveying layer 11 of the first conveying mechanism 1 can convey the first pallet 80 to the roller 55. When the first pallet 80 just contacts the roller 55, the twelfth drive unit can drive the roller 55 to rotate so that the roller 55 can fully support the first pallet 80. Then, the eleventh drive unit 52 drives the lifting member 53 to rotate, thereby driving the supporting member 54 to rise and fall through the lifting member 53. After the first pallet 80 on the roller 55 is lifted to a preset position by the lifting member 53, the twelfth drive unit again drives the roller 55 to rotate to convey the first pallet 80 on the roller 55 to the second conveying layer 12 of the first conveying mechanism 1, thereby achieving the lifting and conveying of the first pallet 80.

[0099] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
