[0002] During the cigarette packaging process, the cigarette packets produced by the packaging main machine need to be conveyed through a cigarette packet conveying channel to the packaging auxiliary machine for transparent paper packaging. For reasonable space layout, multiple bends need to be set in the cigarette packet conveying channel. In actual production, due to the gaps at the joints of the conveyor belts of the conveying bends, there is a risk of scratching the side ears of the cigarette packets when the cigarette packets pass through the bends. If the scratched cigarette packets are not detected and processed in time, defective cigarette packets will flow into the next process, resulting in appearance quality accidents and seriously affecting the production progress.

[0003] In the existing cigarette packet conveying bends, connecting plates are installed at the joints of the conveyor belts, and the cigarette packets can be smoothly conveyed to the next cigarette packet conveying channel. However, no relevant detection device for scratching the side ears of the cigarette packets is provided between the fixed connecting plates and the moving conveyor belts, and it cannot be ensured whether there is a possibility of scratching the side ears of the cigarette packets when the cigarette packets pass through the bends. How to smoothly convey the cigarette packets and at the same time detect whether there is a risk of scratching the side ears of the cigarette packets when the cigarette packets pass through the bends, ensure the smooth production process, and improve the production efficiency have become the technical problems that need to be solved urgently in the current cigarette production process.

[0032] Embodiment

[0033] As Figures 1 to 5 shown, an optimized device for a cigarette packet conveying bend includes a cigarette packet conveying device 100 erected and installed on the ground. The cigarette packet conveying device 100 includes multiple sections of cigarette packet conveying mechanisms 110. In this design, 3 sections are specifically disclosed and introduced, and in actual production, there can be more sections of the cigarette packet conveying mechanisms 110, and they are connected to each other in a bend shape. In this application, the head and tail of each section of the cigarette packet conveying mechanism 110 are connected to each other through a connecting piece and progress in sequence. That is, adjacent two sections of the cigarette packet conveying mechanisms 110 are connected through a connecting plate 200. A cigarette packet side ear scratch detection mechanism 300 is installed below the connecting plate 200. The cigarette packet side ear scratch detection mechanism 300 is used to detect whether the side ears of the cigarette packets conveyed on the cigarette packet conveying device 100 are scratched, so as to ensure the quality of the produced products and prevent defective products from flowing into the next production process.

[0034] The conveying plane of the cigarette packet conveying mechanism 110 on the cigarette packet conveying device 100 gradually decreases from the incoming material end to the feeding end to ensure the smooth conveyance of the small box cigarette packets 400 on the cigarette packet conveying device 100.

[0035] Preferably, the cigarette packet conveying mechanism 110 includes a first mounting bracket 111, a second mounting bracket 112, a third mounting bracket 113, a first conveyor belt 114, a second conveyor belt 115, and a third conveyor belt 116. The first conveyor belt 114 is installed on the first mounting bracket 111 through a first driving roller and a first driven roller, and the first driving roller is driven by a first driving motor; the second conveyor belt 115 is installed on the second mounting bracket 112 through a second driving roller and a second driven roller, and the second driving roller is driven by a second driving motor; the third conveyor belt 116 is installed on the third mounting bracket 113 through a third driving roller and a third driven roller, and the third driving roller is driven by a third driving motor. In summary, each section of the cigarette packet conveying mechanism 110 is driven by a separate motor, and the cigarette packet conveying mechanism 110 is a conventional belt conveying mechanism.

[0036] In some preferred embodiments, the connecting plate 200 includes a first connecting plate 210 and a second connecting plate 220; wherein, the first connecting plate 210 is installed at the connection of the first conveyor belt 114 and the second conveyor belt 115; the second connecting plate 220 is installed at the connection of the second conveyor belt 115 and the third conveyor belt 116. The setting of the connecting plate 200 can smoothly transition and connect the head and tail of each cigarette pack conveying mechanism 110, ensuring that the small box cigarette packs 400 can be smoothly conveyed in the cigarette pack conveying device 100.

[0037] In some preferred embodiments, the top surface of the second connecting plate 220 is higher than the conveying surface of the third conveyor belt 116, the conveying surface of the second conveyor belt 115 is higher than the top surface of the second connecting plate 220, the top surface of the first connecting plate 210 is higher than the conveying surface of the second conveyor belt 115, and the conveying surface of the first conveyor belt 114 is higher than the top surface of the first connecting plate 210.

[0038] In some preferred embodiments, the cigarette pack side ear scratch detection mechanism 300 is respectively installed below the first connecting plate 210 and the second connecting plate 220; specifically, the cigarette pack side ear scratch detection mechanism 300 includes a metal shrapnel 310, a metal shrapnel limit block 320, a proximity switch support frame 330 and a proximity switch 340, and the proximity switch 340 is installed on the proximity switch support frame 330. It is further explained that the proximity switch 340 is installed at the highest position of the proximity switch support frame 330 as much as possible to ensure that the installation position of the proximity switch 340 is close to the height of the end position of the metal shrapnel 310 to ensure the sensitivity during the detection process. The metal shrapnel limit block 320 is installed on the proximity switch support frame 330 and is located in front of the sensing end of the proximity switch 340. The purpose is to avoid the metal shrapnel 310 from damaging the proximity switch 340 due to elastic deformation during the detection process. The sensing end (detection head) of the metal shrapnel limit block 320 is used to protect the proximity switch 340. The metal shrapnel limit block 320 is parallel to the proximity switch support frame 330. The metal shrapnel 310 is installed in front of the metal shrapnel limit block 320. The contact end of the metal shrapnel 310 faces upward (vertically upward) to detect the side ears of the incoming small box cigarette package 400. The metal shrapnel 310 is initially parallel to the metal shrapnel limit block 320. When the side ears 410 of the small box cigarette package 400 abut against the metal shrapnel 310, the metal shrapnel 310 undergoes elastic deformation. In order to avoid damage during the detection of the small box cigarette package 400, the contact end of the metal shrapnel 310 is wrapped with a soft protective layer, that is, the metal shrapnel 310 should have sufficient toughness and the end material is soft. The toughness is to facilitate the reset of the toggle and rebound, and the softness is to avoid damage to the cigarette package during the transportation process.

[0039] Under normal circumstances, the small cigarette pack 400 can be smoothly transported in the cigarette pack conveying device 100 (i.e., the small cigarette pack 400 can be smoothly conveyed to the first connecting plate 210 via the first conveying belt 114, and then conveyed forward via the second conveying belt 115, and the second conveying belt 115 drives the small cigarette pack 400 to be conveyed to the third conveying belt 116 via the second connecting plate 220, and the cigarette pack can smoothly pass through the bend);

[0040] Under abnormal circumstances, due to factors such as random errors of packaging materials and friction of mechanical surfaces, the side ears of the cigarette packs 400 are likely to be scratched or punctured in the gap between the conveyor belt and the connecting plate 200 during the process of the small cigarette packs 400 from the conveyor belt to the connecting plate 200;

[0041] Specific detection principle (working principle) of the cigarette pack side ear scratch detection mechanism 300: When there is damage or puncture of the cigarette pack side ear during the conveying process, during the conveyance of the defective cigarette pack on the conveyor belt, when it passes through the metal shrapnel 310, the damaged or punctured side ear 410 of the cigarette pack impacts the metal shrapnel 310 that was originally in a normal state (i.e., the metal shrapnel 310 is parallel to the detection plane of the proximity switch 340), causing the metal shrapnel 310 to undergo elastic deformation. At this time, the proximity switch 340 installed on the proximity switch support frame 330 detects that the distance between it and the metal shrapnel 310 has decreased, indicating that the side ear of the cigarette pack has been scratched. Then, the proximity switch 340 sends a signal to the controller, the packaging main machine stops, and the conveyor belt that has passed through stops moving (regarding the transmission logic of the proximity switch signal, this is an existing technology and will not be explained in detail here). The operator manually removes the defective cigarette pack or removes the defective cigarette pack through the corresponding removal device. When the bent metal shrapnel 310 rebounds to the normal state, the device continues to work.

[0042] Preferably, a cigarette pack guardrail assembly 120 is provided on the cigarette pack conveying device 100. The cigarette pack guardrail assembly 120 includes a cigarette pack guardrail 121 and guardrail fixing blocks 122. The guardrail fixing blocks 122 are respectively installed on the first mounting bracket 111, the second mounting bracket 112, and the third mounting bracket 113. The cigarette pack guardrail 121 is installed on the guardrail fixing blocks 122. The cigarette pack guardrail 121 can guide the cigarette pack and prevent the cigarette pack from falling out of the conveying device during the conveying process.

[0043] In summary, the present utility model provides an optimized device for the cigarette pack conveying bend. In this device, a cigarette pack conveying device and a side ear scratch detection mechanism are designed, effectively solving the problems existing in the cigarette pack conveying bend, and timely detecting to avoid defective cigarette packs flowing into the next process, resulting in appearance quality accidents and affecting the production progress. The present utility model can adjust and set the corresponding mechanism dimensions and installation positions according to the actual production to meet the optimization of the cigarette pack conveying bend of different brands of cigarettes. At the same time, the bend optimization device has a simple structure, is simple and practical, has a high detection accuracy, strong reliability, low cost and is suitable for application. It can accurately detect appearance quality problems such as scratches and punctures on the side ears of cigarette packs, avoid defective cigarette packs flowing into the next production process and causing quality accidents, eliminate the hidden danger of blocking and reworking cigarettes, ensure the smooth production process, and further improve production efficiency.
