Description

Technical Field

[0001] This invention relates to the field of tobacco packaging printing technology, and in particular to a cigarette label conveying system. Background Technology

[0002] Currently, in the downstream processes of cigarette label printing and die-cutting production, due to the lack of a logistics connection device between the production machine and the downstream automatic bundling equipment, the operation mode of manual handling is still adopted.

[0003] This model results in the stacks of cigarette labels produced by the machine relying entirely on manual collection and turnover. The efficiency and stability of manual handling cannot keep up with the high-speed production rhythm of the machine. This discontinuous operation mode severely restricts production efficiency, and the high-intensity repetitive labor often causes products to tip over, scatter, or break during the transfer process, increasing the scrap rate.

[0004] In addition, the existing manual handling process makes it difficult to ensure the consistency of the head and tail direction when the cigarette labels enter the bundling machine. Moreover, once the bundling equipment malfunctions or the production capacity is saturated, the front-end machine is often forced to stop due to material discharge congestion, which seriously restricts the overall efficiency and automation level of the entire intelligent production line. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing a cigarette label conveying system that can achieve fully automated conveying of cigarette label materials without stopping the machine, significantly reducing labor costs while ensuring the continuity, stability, and quality of the entire cigarette label production process.

[0006] This invention proposes a cigarette label conveying system, including a first longitudinal conveying mechanism, a transverse conveying mechanism located at the end of the first longitudinal conveying mechanism, a lifting and transferring mechanism connected to the first longitudinal conveying mechanism, and an overflow buffer mechanism located at the end of the first longitudinal conveying mechanism. The lifting and transferring mechanism is used to drive the first longitudinal conveying mechanism to move up and down. When the first longitudinal conveying mechanism is in a low position, it conveys the material to the transverse conveying mechanism, which then conveys the material to the downstream process. When the first longitudinal conveying mechanism is in a high position, it conveys the material to the overflow buffer mechanism, which buffers the material.

[0007] Furthermore, the cigarette label conveying system also includes a first frame, a material input platform located on one side of the first frame, and a material buffer platform located on the other side of the first frame. The first longitudinal conveying mechanism, the transverse conveying mechanism, the lifting and transferring mechanism, and the overflow buffer mechanism are all located on the first frame. The first longitudinal conveying mechanism is connected to the material input platform, and the overflow buffer mechanism is connected to the material buffer platform.

[0008] Furthermore, the first longitudinal conveying mechanism is equipped with a weighing module, which is used to detect the weight of the material conveyed on the first longitudinal conveying mechanism.

[0009] Furthermore, the cigarette label conveying system also includes a second frame, a rotary reversing mechanism disposed on the second frame, and a second longitudinal conveying mechanism disposed on the second frame. The second longitudinal conveying mechanism is disposed at the end of the transverse conveying mechanism and is used to convey materials to downstream binding equipment. The rotary reversing mechanism is disposed between the transverse conveying mechanism and the second longitudinal conveying mechanism and is used to receive the materials conveyed by the transverse conveying mechanism and convey the materials to the second longitudinal conveying mechanism after reversing their direction.

[0010] Furthermore, the first longitudinal conveying mechanism includes a first belt conveyor seat disposed on the lifting and transplanting mechanism, and a first conveyor belt extending longitudinally on the first belt conveyor seat. The first belt conveyor seat is used to support the first conveyor belt, and the material carried on the first conveyor belt is longitudinally conveyed during operation.

[0011] Furthermore, the lifting and transplanting mechanism includes a first mounting base plate disposed on the first frame, a first lifting cylinder extending vertically on the first mounting base plate, and a first supporting top plate disposed on the top of the first lifting cylinder. The first longitudinal conveying mechanism is disposed on the first supporting top plate so that when the first lifting cylinder extends or retracts, it drives the first longitudinal conveying mechanism to lift or retract.

[0012] Furthermore, the lifting and transplanting mechanism also includes a first lifting guide rod extending in a vertical direction. The first supporting top plate is fixedly connected to the top of the first lifting guide rod, and the first lifting guide rod is slidably connected to the first mounting base plate to guide the lifting and lowering of the first supporting top plate.

[0013] Furthermore, the transverse conveying mechanism includes a transverse support frame disposed on the first frame, and a plurality of transverse conveying rollers distributed transversely on the transverse support frame. The transverse support frame is used to support the plurality of transverse conveying rollers, and the material carried on the plurality of transverse conveying rollers is transversely conveyed during operation.

[0014] Furthermore, the overflow buffer mechanism includes an overflow support frame disposed on the top of the transverse support frame, and a plurality of overflow conveying rollers distributed longitudinally on the overflow support frame. The overflow support frame is used to support the plurality of overflow conveying rollers. During the operation of the plurality of overflow conveying rollers, the material carried on them is longitudinally conveyed to the material buffer platform.

[0015] Furthermore, the rotary reversing mechanism includes a rotary drive component mounted on the second frame, a rotary support frame mounted on the rotary drive component, and a plurality of rotary conveying rollers distributed laterally on the rotary support frame. The rotary drive component is used to drive the rotary support frame to rotate, and the rotary support frame is used to support the plurality of rotary conveying rollers. During the operation of the plurality of rotary conveying rollers, the material carried on them is conveyed laterally.

[0016] Furthermore, the second longitudinal conveying mechanism includes a transverse docking assembly disposed on the second frame and a longitudinal conveying assembly disposed on the second frame. The transverse docking assembly is used to receive the material conveyed by the rotary reversing mechanism, and the longitudinal conveying assembly is used to longitudinally convey the material received by the transverse docking assembly to the downstream strapping equipment.

[0017] Furthermore, the transverse docking assembly includes a docking support frame disposed on the second frame, and a plurality of transverse docking rollers distributed transversely on the docking support frame, wherein the docking support frame supports the plurality of transverse docking rollers so that the plurality of transverse docking rollers are at the same height as the rotary reversing mechanism.

[0018] Furthermore, the longitudinal conveying assembly includes a second belt conveyor seat disposed on the second frame, and a second conveyor belt extending longitudinally on the second belt conveyor seat. One end of the second conveyor belt extends into the transverse docking assembly, and the other end extends into the downstream strapping device, so that during the operation of the second conveyor belt, the material received by the transverse docking assembly is longitudinally conveyed to the downstream strapping device.

[0019] Furthermore, the cigarette label conveying system also includes a lifting mechanism mounted on the second frame, which drives the longitudinal conveying component to move up and down so that the longitudinal conveying component can be connected to the downstream strapping equipment.

[0020] Furthermore, the lifting mechanism includes a second mounting base plate disposed on the second frame, a second lifting cylinder extending vertically on the second mounting base plate, and a second support top plate disposed on the top of the second lifting cylinder. The longitudinal conveying component is disposed on the second support top plate so that when the second lifting cylinder extends or retracts, it drives the longitudinal conveying component to lift or retract.

[0021] Furthermore, the lifting mechanism also includes a second lifting guide rod extending in a vertical direction. The second supporting top plate is fixedly connected to the top of the second lifting guide rod, and the second lifting guide rod is slidably connected to the second mounting base plate to guide the lifting of the second supporting top plate.

[0022] The cigarette label conveying system proposed in this invention has the following beneficial effects:

[0023] (1) An overflow buffer mechanism is set at the end of the first longitudinal conveying mechanism. When there is congestion or overload, excess material can be conveyed to the overflow buffer mechanism for buffering. This enables fully automatic conveying of cigarette label materials without stopping the machine, greatly reducing labor costs while ensuring the continuity, stability and quality of finished product delivery throughout the cigarette label production process.

[0024] (2) This system includes a lifting and transplanting mechanism, which drives the first longitudinal conveying mechanism to lift and lower, so that the first longitudinal conveying mechanism can transport the material to the transverse conveying mechanism or the overflow buffer mechanism, thereby realizing the dual-channel operation of the material and ensuring the continuity of the entire cigarette label production process.

[0025] (3) A weighing module is installed on the first longitudinal conveying mechanism of this system. The weight of the material carried on the first longitudinal conveying mechanism is detected by the weighing module, so as to monitor the quantity of the stacked material in real time and thus ensure the quality of finished product delivery throughout the entire cigarette label production process.

[0026] (3) This system also includes a rotary reversing mechanism and a second longitudinal conveying mechanism. The rotary reversing mechanism is located between the transverse conveying mechanism and the second longitudinal conveying mechanism. The rotary reversing mechanism reverses the direction of the material, and the second longitudinal conveying mechanism continues to convey the material longitudinally, thereby ensuring that the head and tail directions of the material meet the binding requirements of the binding equipment and realizing the adaptation of the logistics of the cigarette label production line to the direction of the binding equipment.

[0027] (4) The second longitudinal conveying mechanism of this system includes a transverse docking component and a longitudinal conveying component. Both the transverse docking component and the longitudinal conveying component are mounted on the second frame. The transverse docking component is used to receive the material conveyed by the rotary reversing mechanism, and the longitudinal conveying component is used to longitudinally convey the material received by the transverse docking component to the downstream strapping equipment, thereby completing the material conveying.

[0028] (5) The system also includes a lifting mechanism, which is set on the second frame. The lifting mechanism drives the second longitudinal conveying component to lift and lower, so that the longitudinal conveying component can be connected with the working platform of the downstream bundling equipment, thereby realizing the connection between the logistics of the cigarette label production line and the bundling equipment.

[0029] (6) This system has constructed a composite conveying system that integrates online weighing and screening, longitudinal belt conveying, orthogonal lifting and transfer and rotational adjustment. It can realize the automatic convergence of multiple cigarette labels and 180-degree rotation adjustment, thereby solving the problem of matching the logistics and binding equipment direction of the cigarette label production line. It significantly reduces labor costs while ensuring the continuity, stability and finished product delivery quality of the entire cigarette label production process. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 8 An embodiment of the present invention provides a cigarette label conveying system, including a first longitudinal conveying mechanism 3, a transverse conveying mechanism 4 disposed at the end of the first longitudinal conveying mechanism 3, a lifting and transplanting mechanism 5 connected to the first longitudinal conveying mechanism 3, and an overflow buffer mechanism 6 disposed at the end of the first longitudinal conveying mechanism 3. The lifting and transplanting mechanism 5 is used to drive the first longitudinal conveying mechanism 3 to move up and down.

[0042] When the first longitudinal conveyor 3 is in a low position, it conveys the material to the transverse conveyor 4, which then conveys the material to the downstream process. When the first longitudinal conveyor 3 is in a high position, it conveys the material to the overflow buffer mechanism 6, which buffers the material.

[0043] In this application, the cigarette label conveying system includes a first longitudinal conveying mechanism 3, a transverse conveying mechanism 4, a lifting and transferring mechanism 5, and an overflow buffer mechanism 6. The transverse conveying mechanism 4 and the overflow buffer mechanism 6 are both located at the end of the first longitudinal conveying mechanism 3 and are used to receive the material on the first longitudinal conveying mechanism 3. The lifting and transferring mechanism 5 is connected to the first longitudinal conveying mechanism 3 and is used to drive the first longitudinal conveying mechanism 3 to move up and down.

[0044] In this application, since the lifting and transplanting mechanism 5 can drive the first longitudinal conveying mechanism 3 to rise and fall, when the downstream bundling equipment 12 is in a normal receiving state, the lifting and transplanting mechanism 5 drives the first longitudinal conveying mechanism 3 to fall, so that at the end of the first longitudinal conveying mechanism 3, the first longitudinal conveying mechanism 3 at the lower position conveys the material to the transverse conveying mechanism 4. After the transverse conveying mechanism 4 receives the material conveyed by the first longitudinal conveying mechanism 3, it transversely conveys the material to the downstream process.

[0045] When the downstream bundling equipment 12 malfunctions or its processing speed lags behind, the lifting and transplanting mechanism 5 drives the first longitudinal conveying mechanism 3 to rise, thereby allowing the first longitudinal conveying mechanism 3, which is at a high position, to transport the material to the overflow buffer mechanism 6 at the end of the first longitudinal conveying mechanism 3.

[0046] The overflow buffer mechanism 6 buffers the materials, thereby achieving fully automated conveying of cigarette label materials without stopping the machine. This significantly reduces labor costs while ensuring the continuity, stability, and quality of the entire cigarette label production process.

[0047] In this application, there are multiple first longitudinal conveying mechanisms 3 arranged at equal intervals along the axial direction of the transverse conveying mechanism 4, and multiple overflow buffer mechanisms 6 corresponding to the multiple first longitudinal conveying mechanisms 3 respectively.

[0048] When multiple first longitudinal conveying mechanisms 3 are in a low position, materials are simultaneously conveyed to the transverse conveying mechanism 4. The transverse conveying mechanism 4 simultaneously receives materials conveyed by multiple first longitudinal conveying mechanisms 3, thereby realizing the automatic convergence of multiple columns of materials and improving the material conveying efficiency.

[0049] When multiple first longitudinal conveying mechanisms 3 are in a high position, the materials are respectively conveyed to the corresponding overflow buffer mechanism 6, thereby buffering the materials through the overflow buffer mechanism 6, and thus realizing fully automatic conveying of cigarette label materials without stopping the machine, ensuring the continuity of the entire cigarette label production process.

[0050] In this embodiment, the cigarette label conveying system also includes a first frame 1, a material input platform 10, and a material buffer platform 11. The first longitudinal conveying mechanism 3, the transverse conveying mechanism 4, the lifting and transferring mechanism 5, and the overflow buffer mechanism 6 are all mounted on the first frame 1. The material input platform 10 is located on one side of the first frame 1, and the material buffer platform 11 is located on the other side of the first frame 1, so that the material input platform 10 is located at the beginning of the first longitudinal conveying mechanism 3, and the material buffer platform 11 is located at the end of the first longitudinal conveying mechanism 3.

[0051] The first longitudinal conveying mechanism 3 is connected to the material input platform 10 at its head end, thereby conveying the material input into the material input platform 10 longitudinally through the operation of the first longitudinal conveying mechanism 3. The overflow buffer mechanism 6 is connected to the material buffer platform 11. When the downstream strapping equipment 12 malfunctions or its processing speed is slow, the first longitudinal conveying mechanism 3, which is at a higher position, conveys the material to the overflow buffer mechanism 6.

[0052] The overflow buffer mechanism 6 then transports the material to the material buffer platform 11, which buffers the material, thereby achieving fully automated conveying of cigarette label materials without stopping the machine. This significantly reduces labor costs while ensuring the continuity, stability, and quality of the entire cigarette label production process.

[0053] In actual production, when cigarette labels are transported to the downstream bundling process through the conveying system, multiple cigarette labels are usually stacked together for transport. After the multiple stacked cigarette labels arrive at the downstream bundling process, the bundling equipment 12 bundles the multiple stacked cigarette labels together to form a bundle of cigarette labels.

[0054] In this embodiment, a weighing module is installed on the first longitudinal conveying mechanism 3. During the longitudinal conveying of materials by the first longitudinal conveying mechanism 3, the weighing module detects the weight of the materials conveyed on the first longitudinal conveying mechanism 3. Since the weight of each cigarette label is within a certain range, the weight data detected by the weighing module can be used to determine whether the quantity of materials meets the standard.

[0055] If the quantity of materials is insufficient, the weighing module transmits an electrical signal to the control system. The control system then controls the lifting and transferring mechanism 5 to operate, causing the lifting and transferring mechanism 5 to drive the first longitudinal conveying mechanism 3 to rise to a high position. This allows the first longitudinal conveying mechanism 3 to transport the insufficient materials to the overflow buffer mechanism 6, which then transports them to the material buffer platform 11 for further processing.

[0056] If the quantity of materials meets the standard, the weighing module transmits an electrical signal to the control system. The control system then controls the lifting and transferring mechanism 5 to operate, causing the lifting and transferring mechanism 5 to drive the first longitudinal conveying mechanism 3 to descend to a low position. This allows the first longitudinal conveying mechanism 3 to transport the qualified materials to the transverse conveying mechanism 4, which then transports the materials to the downstream bundling process. This ensures that all materials transported to the downstream bundling process are of the required quantity, thereby ensuring the quality of finished product delivery throughout the entire cigarette label production process.

[0057] In this embodiment, the cigarette label conveying system further includes a second frame 2, a rotation reversing mechanism 7, and a second longitudinal conveying mechanism 8. The rotation reversing mechanism 7 and the second longitudinal conveying mechanism 8 are both mounted on the second frame 2. The second longitudinal conveying mechanism 8 is located at the end of the transverse conveying mechanism 4, and the rotation reversing mechanism 7 is located between the transverse conveying mechanism 4 and the second longitudinal conveying mechanism 8.

[0058] After the transverse conveying mechanism 4 conveys the material transversely, at the end of the transverse conveying mechanism 4, the rotary reversing mechanism 7 receives the material on the transverse conveying mechanism 4, reverses the direction of the material, and continues to convey it transversely to the second longitudinal conveying mechanism 8; after the second longitudinal conveying mechanism 8 receives the material conveyed by the rotary reversing mechanism 7, it conveys the material longitudinally to the downstream strapping equipment 12.

[0059] Since the bundling equipment 12 needs to ensure that the head and tail directions of the cigarette labels meet the requirements when bundling multiple stacked cigarette labels together, in this application, the first longitudinal conveying mechanism 3 conveys the material longitudinally, the transverse conveying mechanism 4 conveys the material transversely, the rotary reversing mechanism 7 reverses the direction of the material, and the second longitudinal conveying mechanism 8 continues to convey the material longitudinally, thereby ensuring that the head and tail directions of the material meet the bundling requirements of the bundling equipment 12, and realizing the adaptation of the logistics of the cigarette label production line with the direction of the bundling equipment 12.

[0060] Specifically, in this embodiment, the first longitudinal conveying mechanism 3 includes a first belt conveyor seat 31 and a first conveyor belt 32. The first conveyor belt 32 extends longitudinally on the first belt conveyor seat 31, thereby supporting the first conveyor belt 32 through the first belt conveyor seat 31, so that when the first conveyor belt 32 is running, it longitudinally conveys the material carried on it.

[0061] It is foreseeable that in actual implementation, there are two first conveyor belts 32 installed on the first belt conveyor seat 31. The two first conveyor belts 32 support the two ends of the material respectively, so that when the two first conveyor belts 32 are running, they drive the material to move longitudinally at the same time, thereby ensuring the stability of the longitudinal conveying of the material.

[0062] The first belt conveyor seat 31 is mounted on the lifting and transplanting mechanism 5. The lifting and transplanting mechanism 5 drives the first belt conveyor seat 31 to rise and fall, thereby driving the first conveyor belt 32 and the material carried on it to rise and fall. When the first conveyor belt 32 is in a low position, the material carried on it is transported to the transverse conveying mechanism 4; when the first conveyor belt 32 is in a high position, the material carried on it is transported to the overflow buffer mechanism 6.

[0063] In actual implementation, the weighing module is based on a data processing system and a strain gauge sensor installed at the head end of the first conveyor belt 32. The strain gauge sensor senses the weight of the material carried on the first conveyor belt 32 and transmits the detected weight information to the data processing system. The data processing system analyzes and processes the weight information of the material and judges the abnormality of the material quantity through weight deviation, thereby realizing real-time monitoring of the material quantity and ensuring the quality of finished product delivery throughout the entire cigarette label production process.

[0064] Specifically, in this embodiment, the lifting and transplanting mechanism 5 includes a first mounting base plate 51, a first lifting cylinder 52, and a first supporting top plate 53. The first mounting base plate 51 is fixedly installed in the first frame 1, the first lifting cylinder 52 is fixedly installed on the first mounting base plate 51 and extends vertically on the first mounting base plate 51, and the first supporting top plate 53 is disposed on the top of the first lifting cylinder 52, thereby realizing the installation of the lifting and transplanting mechanism 5 on the first frame 1.

[0065] The first longitudinal conveying mechanism 3 is mounted on the first supporting top plate 53. Specifically, the first belt conveyor seat 31 is fixedly mounted on the first supporting top plate 53. When the first lifting cylinder 52 extends or retracts, driving the first supporting top plate 53 to rise or fall, the first supporting top plate 53 drives the first belt conveyor seat 31 to rise or fall, thereby realizing the overall lifting and lowering of the first longitudinal conveying mechanism 3.

[0066] Furthermore, in this embodiment, the lifting and transplanting mechanism 5 also includes a first lifting guide rod 54, which extends vertically within the first frame 1. The first supporting top plate 53 is fixedly connected to the top of the first lifting guide rod 54, and the bottom of the first lifting guide rod 54 penetrates through the first mounting base plate 51 and is slidably connected to the first mounting base plate 51.

[0067] When the first lifting cylinder 52 extends and retracts, driving the first support top plate 53 to rise and fall, the first support top plate 53 drives the first lifting guide rod 54 to rise and fall synchronously. During this process, the first lifting guide rod 54 guides the rise and fall of the first support top plate 53 through the sliding cooperation between the first lifting guide rod 54 and the first mounting base plate 51, thereby making the rise and fall of the first support top plate 53 more stable, and thus improving the stability of the rise and fall of the first longitudinal conveying mechanism 3.

[0068] Specifically, in this embodiment, the transverse conveying mechanism 4 includes a transverse support frame 41 and a plurality of transverse conveying rollers 42. The transverse support frame 41 is fixedly mounted on the first frame 1, and the plurality of transverse conveying rollers 42 are distributed transversely on the transverse support frame 41, thereby supporting the plurality of transverse conveying rollers 42 through the transverse support frame 41, so that when the plurality of transverse conveying rollers 42 are running, the material carried on them is transversely conveyed.

[0069] In order to ensure that the first longitudinal conveying mechanism 3 can smoothly transfer the material to the transverse conveying mechanism 4, in this application, when the first longitudinal conveying mechanism 3 is in a low position, its end extends to the transverse conveying mechanism 4. That is, at the corresponding position of the transverse conveying mechanism 4, the end of the first conveyor belt 32 extends to the space between two adjacent transverse conveying rollers 42.

[0070] It is foreseeable that in actual implementation, the lateral distance between two adjacent transverse conveying rollers 42 is less than the length of the material, and at the corresponding position of the transverse conveying mechanism 4, the lateral distance between two adjacent transverse conveying rollers 42 is greater than the width of the first conveyor belt 32. Thus, when the first conveyor belt 32 is in a low position, it is located between two adjacent transverse conveying rollers 42. At this time, the material carried on the first conveyor belt 32 is pressed against part of the transverse conveying rollers 42, thereby the material is transversely conveyed by the operation of multiple transverse conveying rollers 42.

[0071] In this application, the cigarette label conveying system also includes a positioning detection module. Specifically, the positioning detection module is located in the first frame 1, below the multiple transverse conveying rollers 42. When the first conveyor belt 32 is in a low position, conveying material onto the multiple transverse conveying rollers 42, the positioning detection module detects that the material has reached a preset position and transmits an electrical signal to the control system. The control system then controls the first conveyor belt 32 to stop running and simultaneously controls the multiple transverse conveying rollers 42 to start running, thereby enabling the multiple transverse conveying rollers 42 to transversely convey the material, achieving fully automatic material conveying.

[0072] In actual implementation, the arrival detection module is a proximity switch installed below multiple transverse conveyor rollers 42. When the proximity switch senses that the first conveyor belt 32 has transported the material to the designated position on the multiple transverse conveyor rollers 42, it transmits an electrical signal to the control system, causing the control system to control the first conveyor belt 32 to stop running and at the same time control the multiple transverse conveyor rollers 42 to start running.

[0073] Specifically, in this embodiment, the overflow buffer mechanism 6 includes an overflow support frame 61 and a plurality of overflow conveying rollers 62. The overflow support frame 61 is fixedly mounted on the top of the transverse support frame 41, and the plurality of overflow conveying rollers 62 are longitudinally distributed on the overflow support frame 61, thereby supporting the plurality of overflow conveying rollers 62 through the overflow support frame 61, so that the plurality of overflow conveying rollers 62 are located above the plurality of transverse conveying rollers 42 and are arranged opposite to the first conveyor belt 32.

[0074] When the first conveyor belt 32 is in a high position, it is located above multiple transverse conveyor rollers 42 and is connected to the overflow conveyor roller 62, so that the first conveyor belt 32 conveys the material it carries to the overflow conveyor roller 62. Then, through the operation of multiple overflow conveyor rollers 62, the material is longitudinally conveyed to the material buffer platform 11, and then the material buffer platform 11 buffers the material.

[0075] It is foreseeable that in actual implementation, the longitudinal distance between two adjacent overflow conveyor rollers 62 is less than the width of the material. Thus, when the first conveyor belt 32 conveys the material it carries onto the overflow conveyor rollers 62, the material is longitudinally conveyed sequentially by multiple overflow conveyor rollers 62.

[0076] Specifically, in this embodiment, the rotary reversing mechanism 7 includes a rotary drive 71, a rotary support frame 72, and a plurality of rotary conveying rollers 73. The rotary drive 71 is mounted on the second frame 2, and the rotary support frame 72 is mounted on the rotary drive 71, thereby driving the rotary support frame 72 to rotate. The plurality of rotary conveying rollers 73 are laterally distributed on the rotary support frame 72, thereby supporting the plurality of rotary conveying rollers 73 and placing them at the same height as the plurality of transverse conveying rollers 42.

[0077] When conveying materials laterally, the materials are first conveyed laterally to multiple rotating conveyor rollers 73 by multiple transverse conveyor rollers 42. Then, the rotating support frame 72 is driven to rotate 180° by the rotating drive component 71, which drives the multiple rotating conveyor rollers 73 and the materials they carry to rotate 180°, thereby realizing the reversal of the material direction. Finally, the materials are conveyed to the second longitudinal conveyor mechanism 8 by the operation of the multiple rotating conveyor rollers 73, thereby ensuring that the head and tail directions of the materials meet the binding requirements of the binding equipment 12, and realizing the adaptation of the logistics of the cigarette label production line with the direction of the binding equipment 12.

[0078] In actual implementation, the rotary drive component 71 can be a rotary cylinder, rotary motor or other rotary drive device.

[0079] In this embodiment, the second longitudinal conveying mechanism 8 includes a transverse docking component 81 and a longitudinal conveying component 82, both of which are mounted on the second frame 2.

[0080] When the rotary reversing mechanism 7 conveys the material laterally after reversing, the material conveyed by the rotary reversing mechanism 7 is first received by the transverse docking component 81, and then the material received by the transverse docking component 81 is longitudinally conveyed to the downstream strapping equipment 12 by the longitudinal conveying component 82. This ensures that the head and tail directions of the material meet the strapping requirements of the strapping equipment 12, and realizes the adaptation of the logistics of the cigarette label production line with the direction of the strapping equipment 12.

[0081] Specifically, in this embodiment, the transverse docking assembly 81 includes a docking support frame 811 and a plurality of transverse docking rollers 812. The docking support frame 811 is fixedly mounted on the second frame 2, and the plurality of transverse docking rollers 812 are distributed transversely on the docking support frame 811, thereby supporting the plurality of transverse docking rollers 812 through the docking support frame 811, so that the plurality of transverse docking rollers 812 and the plurality of rotating conveying rollers 73 are at the same height.

[0082] After the rotary reversing mechanism 7 completes the material reversal, the material is laterally conveyed to the multiple transverse docking rollers 812 by the operation of multiple rotary conveying rollers 73. The multiple transverse docking rollers 812 receive the material, and then the longitudinal conveying component 82 conveys the material carried on the multiple transverse docking rollers 812 longitudinally to the downstream strapping equipment 12, thereby completing the material conveying.

[0083] Specifically, in this embodiment, the longitudinal conveying assembly 82 includes a second belt conveyor seat 821 and a second conveyor belt 822. The second belt conveyor seat 821 is disposed on the second frame 2, and the second conveyor belt 822 extends longitudinally on the second belt conveyor seat 821, thereby supporting the second conveyor belt 822.

[0084] One end of the second conveyor belt 822 extends into the transverse docking assembly 81, and the other end extends into the downstream strapping device 12. Specifically, one end of the second conveyor belt 822 extends between two adjacent transverse docking rollers 812, so that when the second conveyor belt 822 is running, the material carried on the multiple transverse docking rollers 812 is longitudinally conveyed to the downstream strapping device 12, thus completing the material conveying.

[0085] It is foreseeable that in actual implementation, there are two second conveyor belts 822 installed on the second belt conveyor seat 821. Each of the two second conveyor belts 822 extends between two adjacent transverse connecting rollers 812, thereby supporting both ends of the material through the two second conveyor belts 822 respectively. When the two first conveyor belts 32 are running, they simultaneously drive the material to move longitudinally, thereby ensuring the stability of the longitudinal conveying of the material.

[0086] In this embodiment, the cigarette label conveying system also includes a lifting mechanism 9, which is mounted on the second frame 2 and is used to drive the longitudinal conveying assembly 82 to move up and down. When the lifting mechanism 9 drives the longitudinal conveying assembly 82 to descend, so that the longitudinal conveying assembly 82 is in a low position, the second conveyor belt 822 of the longitudinal conveying assembly 82 is at the same height as the multiple transverse docking rollers 812. At this time, the material carried on the multiple transverse docking rollers 812 is pressed against the second conveyor belt 822, so that the material carried on the multiple transverse docking rollers 812 is longitudinally conveyed when the second conveyor belt 822 is running.

[0087] When the lifting mechanism 9 drives the longitudinal conveying component 82 to rise, so that the longitudinal conveying component 82 is at a high position, the second conveyor belt 822 of the longitudinal conveying component 82 is at the same height as the working platform of the downstream binding equipment 12, so that the second conveyor belt 822 longitudinally conveys the material to the working platform of the downstream binding equipment 12, realizing the docking of the logistics of the cigarette label production line with the binding equipment 12.

[0088] Specifically, in this embodiment, the lifting mechanism 9 includes a second mounting base plate 91, a second lifting cylinder 92, and a second supporting top plate 93. The second mounting base plate 91 is fixedly installed in the second frame 2, the second lifting cylinder 92 is fixedly installed on the second mounting base plate 91 and extends vertically on the second mounting base plate 91, and the second supporting top plate 93 is fixedly disposed on the top of the second lifting cylinder 92, thereby realizing the installation of the lifting mechanism 9 on the first frame 1.

[0089] The longitudinal conveying assembly 82 is mounted on the first supporting top plate 53. Specifically, the second belt conveyor seat 821 is fixedly mounted on the second supporting top plate 93. When the second lifting cylinder 92 extends or retracts, driving the second supporting top plate 93 to rise or fall, the second supporting top plate 93 drives the second belt conveyor seat 821 to rise or fall, thereby realizing the overall lifting and lowering of the longitudinal conveying assembly 82.

[0090] Furthermore, in this embodiment, the lifting mechanism 9 also includes a second lifting guide rod 94, which extends vertically within the second frame 2. The second support top plate 93 is fixedly connected to the top of the second lifting guide rod 94, and the bottom of the second lifting guide rod 94 penetrates through the second mounting base plate 91 and is slidably connected to the second mounting base plate 91.

[0091] When the second lifting cylinder 92 extends and retracts, driving the second support top plate 93 to rise and fall, the second support top plate 93 drives the second lifting guide rod 94 to rise and fall synchronously. During this process, the second lifting guide rod 94 guides the rise and fall of the second support top plate 93 through the sliding cooperation with the second mounting base plate 91, thereby making the rise and fall of the second support top plate 93 more stable, and thus improving the stability of the rise and fall of the longitudinal conveying component 82.

[0092] This invention constructs a composite conveying system integrating online weighing and screening, longitudinal belt conveying, orthogonal lifting and transfer, and rotational adjustment correction. It can realize automatic convergence of multiple cigarette labels and 180-degree rotation adjustment. At the rear end, an overflow buffer mechanism is set up so that when there is congestion or overload, excess material can be directly conveyed to the material buffer platform 11 through the overflow conveyor roller 62. Thus, it can achieve dual-channel operation with fully automatic conveying as the main function and manual buffering as the auxiliary function without stopping the machine. It solves the problem of adapting the logistics of the cigarette label production line to the bundling machine equipment, significantly reduces labor costs, and ensures the continuity, stability and finished product delivery quality of the entire cigarette label production process.

[0093] The above-described contents can be implemented individually or in various combinations, and these variations are all within the protection scope of this invention.
