Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging, and more specifically to a dual-inlet full-size cigarette stacking device. Background Technology

[0002] In the current cigarette packaging industry, stacking machines are commonly used to stack cigarette boxes. These machines employ symmetrical chain drive, and because the receiving plate can only move along the entire chain structure, they suffer from a high damage rate when stacking irregularly shaped cigarettes. They are more suitable for stacking standard medium and slim cigarette boxes. Furthermore, due to their working principle, the stacked cigarette boxes fall into a receiving platform, and then a pushing device pushes them into a conveyor for the next packaging step. This method is not only inconvenient for packaging all specifications of cigarette boxes, but also inefficient and unfavorable for production implementation. Utility Model Content

[0003] This invention overcomes the shortcomings of the prior art and provides a dual-inlet full-size stacking cigarette device.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] A dual-inlet, full-specification smoke stacking device includes a first smoke inlet conveyor line, a second smoke inlet conveyor line, a wrapping machine, and a heat shrink oven.

[0006] The first smoke inlet conveyor line is equipped with a first smoke inlet belt, and the first smoke inlet belt is equipped with a first lifting smoke inlet mechanism and a second lifting smoke inlet mechanism. A smoke stacking device is provided at the smoke outlet of the first smoke inlet belt, and a smoke pushing device is provided on the smoke receiving structure of the smoke stacking device.

[0007] The second smoke inlet conveyor line is equipped with a second smoke inlet belt, which is equipped with a visual recognition device and a smoke-pushing device. At the smoke outlet of the second smoke inlet belt, there is a corresponding tiered belt. At both ends of the tiered belt, there are lifting smoke baffles. At the smoke outlet of the tiered belt, there is a corresponding direct-draw smoke stacking device.

[0008] The direct-extraction stacking device includes a stacking machine and a smoke-supporting conveying device. The stacking machine is positioned above the smoke-supporting conveying device. The smoke-supporting conveying device is configured in conjunction with the smoke-pushing device and the wrapping machine of the first smoke inlet conveying line. The wrapping machine is configured in conjunction with the heat shrink oven.

[0009] The stacking machine has multiple smoke-supporting devices vertically arranged at equal intervals inside its casing. Each smoke-supporting device has two symmetrically opening and closing smoke-supporting plates, which are slidably connected to the device. The plates are also coordinated with the actuators on the device. The casing has a smoke inlet that is coordinated with the smoke-supporting device at the top and the smoke outlet of the conveyor belt. Baffles are located inside the casing on both sides of the smoke inlet.

[0010] The smoke-collecting device includes a fixed plate, a slide rail, a smoke-collecting plate, and a driver. There are two fixed plates symmetrically arranged on the left and right sides of the smoke stacking machine housing, with a gap between the two fixed plates. The gaps form a smoke-collecting passage. Each fixed plate is provided with one or more slide rails. The two smoke-collecting plates are respectively set on the slide rails of the corresponding fixed plates. When the two smoke-collecting plates are in the closed state, they block the gap between the two fixed plates. The smoke-collecting plates are configured in conjunction with the driver.

[0011] The casing of the cigarette stacking machine is provided with multiple sliding grooves. The number and position of the sliding grooves are matched with the cigarette support plates of each cigarette support device. The casing of the cigarette stacking machine near the sliding grooves is provided with slider tracks. Each slider track is provided with a linkage slider. The linkage slider is fixedly connected to the corresponding cigarette support plate and is connected to the corresponding driver.

[0012] The driver uses a drive motor or cylinder.

[0013] The linkage slider is connected to the corresponding driver via a drive belt.

[0014] The cigarette stacking machine housing is equipped with multiple sets of drive wheels, with two drive wheels in each set, which are respectively located on the left and right sides of the cigarette stacking machine housing. The position of each set of drive wheels matches the corresponding cigarette holding device, and the drive belt is nested in a ring on the drive wheels.

[0015] The two drive wheels in the same group divide the drive belt into a first belt body closer to the cigarette stacker housing and a second belt body farther away from the cigarette stacker housing. The two linkage sliders corresponding to the same cigarette holding device are fixedly connected to the first belt body and the second belt body respectively.

[0016] The cigarette conveying device is equipped with a transport platform, a drive chain, a cigarette pusher, a cigarette receiving platform, and a lifting device. The transport platform is a strip platform, which is set up in conjunction with the cigarette pusher and the wrapping machine of the first cigarette inlet conveyor line. The cigarette conveying devices on both sides of the transport platform are symmetrically equipped with drive chains, and multiple cigarette pushers are equidistantly arranged on the drive chains. The cigarette receiving platform is set up on the transport platform, and its position matches that of the cigarette conveying device. The cigarette receiving platform is set on the lifting device.

[0017] Smoke deflectors are installed on both sides of the transport platform.

[0018] The first smoke inlet belt corresponding to the first and second lifting smoke inlet mechanisms is a conveyor belt structure with two belt bodies, and a counting device is provided at the gap between the two conveyor belt bodies.

[0019] The beneficial effects of this utility model are as follows:

[0020] This solution overcomes the problem of existing cigarette stacking machines requiring additional equipment to place stacked cigarette boxes onto a conveyor belt for transport. In this solution, the direct-draw cigarette stacking device employs a multi-bin structure that directly connects to the conveyor belt to arrange cigarette boxes into neat layers. Therefore, it is suitable for irregularly shaped cigarette boxes without the problems of jamming or dropping boxes that occur with existing stacking machines. After arranging the cigarette boxes, the neat layers are dropped layer by layer until they fall onto the conveyor belt. Repeating this process effectively stacks multiple layers of cigarette boxes. It effectively adapts to irregularly shaped cigarette boxes and allows stacked boxes to be stacked directly within the conveyor, avoiding the need for additional equipment and significantly improving efficiency. Furthermore, this device employs a two-production-line design, making packaging more efficient and compatible with different types of cigarette stacking machines, making the device more flexible, versatile, and suitable for widespread use.

[0032] The first smoke inlet conveyor line is provided with a first smoke inlet belt 13, and the first smoke inlet belt 13 is provided with a first lifting smoke inlet mechanism 14 and a second lifting smoke inlet mechanism 15. The smoke outlet of the first smoke inlet belt 13 is provided with a stacking smoke device 16, and the smoke receiving structure of the stacking smoke device 16 is provided with a pushing smoke device 17.

[0033] The second smoke inlet conveyor line is equipped with a second smoke inlet belt 18, which is equipped with a visual recognition device 19 and a smoke-pushing device 20. At the smoke outlet of the second smoke inlet belt 18, there is a corresponding arrangement belt 21. At both ends of the arrangement belt 21, there are lifting smoke baffles 22. At the smoke outlet of the arrangement belt 21, there is a corresponding direct-draw smoke stacking device.

[0034] The direct-extraction stacking device includes a stacking machine and a smoke conveying device. The stacking machine is positioned above the smoke conveying device.

[0036] The smoke-collecting device 2 includes a fixed plate 203, a slide rail 204, a smoke-collecting plate 201, and a driver 202. The number of fixed plates 203 is two, which are symmetrically arranged on the left and right sides of the smoke stacking machine housing 1. There is a gap between the two fixed plates 203, and the gaps form a smoke-falling passage. Each fixed plate 203 is provided with one or more slide rails 204. The two smoke-collecting plates 201 are respectively arranged on the slide rails 204 of the corresponding fixed plates 203. When the two smoke-collecting plates 201 are in the closed state, they block the gap between the two fixed plates 203. The smoke-collecting plates 201 are configured in conjunction with the driver 202.

[0037] The stacking cigarette machine housing 1 is provided with multiple sliding grooves 102. The number and position of the sliding grooves 102 are matched with the cigarette support plates 201 of each cigarette support device 2. The stacking cigarette machine housing 1 near the sliding grooves 102 is provided with slider tracks 3. Each slider track 3 is provided with a linkage slider 4. The linkage slider 4 is fixedly connected to the corresponding cigarette support plate 201. The linkage slider 4 is also connected to the corresponding driver 202.

[0038] The driver 202 is a drive motor or cylinder.

[0039] The linkage slider 4 is connected to the corresponding driver 202 via the drive belt 5.

[0040] The casing 1 of the cigarette stacking machine is equipped with multiple sets of drive wheels 6, with two drive wheels 6 in each set, which are respectively set on the left and right sides of the casing 1 of the cigarette stacking machine. The position of each set of drive wheels 6 matches the corresponding cigarette holding device 2, and the drive belt 5 is nested in a ring on the drive wheels 6.

[0041] The two drive wheels 6 in the same group divide the drive belt 5 into a first belt body close to the cigarette stacking machine housing 1 and a second belt body away from the cigarette stacking machine housing 1. The two linkage sliders 4 corresponding to the same cigarette holding device 2 are fixedly connected to the first belt body and the second belt body respectively.

[0042] The cigarette conveying device is equipped with a transport platform 7, a transmission chain 8, a cigarette pusher 9, a cigarette receiving platform 10, and a lifting device 11. The transport platform 7 is a strip platform. The transport platform 7 is set up in conjunction with the cigarette pusher 17 and the wrapping machine 23 of the first cigarette inlet conveying line. The transmission chains 8 are symmetrically arranged on the cigarette conveying devices on both sides of the transport platform 7. Multiple cigarette pushers 9 are equidistantly arranged on the transmission chains 8. The cigarette receiving platform 10 is set on the transport platform 7. The position of the cigarette receiving platform 10 matches that of the cigarette holding device 2. The cigarette receiving platform 10 is set on the lifting device 11.

[0043] Smoke baffles 12 are installed on both sides of the transport platform 7.

[0044] The first smoke inlet belt 13 corresponding to the first lifting smoke inlet mechanism 14 and the second lifting smoke inlet mechanism 15 is a conveyor belt structure with two belts, and a counting device is provided at the gap between the two conveyor belts.

[0045] The working principle of this utility model is as follows: Figure 1 and Figure 2 As shown, this solution uses both the first and second smoke inlet conveyor lines to transport the cigarette boxes simultaneously, which can effectively improve the efficiency of the packaging line.

[0046] The first smoke inlet conveyor line uses the first smoke inlet belt 13 to inlet the cigarette boxes sequentially through the first lifting smoke inlet mechanism 14 and the second lifting smoke inlet mechanism 15 until they reach the stacking device 16 for stacking. The stacking device 16 drops the stacked cigarette boxes onto the receiving structure, and the pushing device 17 pushes them into the transport platform 7 for further transport until they are finally wrapped and thermoplasticized by the wrapping machine 23 and the heat shrink oven 24.

[0047] Preferably, the first lifting smoke inlet mechanism 14 and the second lifting smoke inlet mechanism 15 have the same structure. The lifting smoke inlet mechanism adopts a structure in which a lifting motor or lifting cylinder drives the conveyor sponge smoke pressing belt. The lifting device controls the up and down movement of the sponge smoke pressing belt. When it is necessary to stop the forward movement of the cigarette box, the sponge smoke pressing belt falls to press down the cigarette box, preventing it from moving. When it is necessary for the cigarette box to move forward, the sponge smoke pressing belt rises. The sponge smoke pressing belt is driven by a rotary motor, which keeps it running at a relative speed with the cigarette box, making the overall smoke pressing process more stable. Furthermore, in order to make the production line more suitable for the transportation of long cigarettes, the first smoke inlet belt 13 corresponding to the first lifting smoke inlet mechanism 14 and the second lifting smoke inlet mechanism 15 is set as a double belt structure. A counting device is set in the middle gap for counting. The counting device adopts a laser counting device, which can effectively utilize space and is suitable for packaging long cigarettes.

[0048] Furthermore, such as Figure 1 and Figure 2As shown, the cigarette stacking device 16 has a conveying device on its cigarette receiving platform mechanism. After the stacked cigarette boxes pass through the conveying device, they are then pushed by the cigarette pushing device 17. Based on this, to further increase efficiency, such as... Figure 3 As shown, the smoke pushing device 17 is directly installed at the bottom of the smoke stacking device 16, compared to... Figure 1 and Figure 2 The setting allows stacked cigarette boxes to be pushed into the corresponding conveyor line more quickly.

[0049] The second smoke inlet conveyor line uses the second smoke inlet belt 18 to inlet smoke, and uses a visual recognition device 19 to identify and locate the cigarette boxes, and pushes the cigarette boxes into the correct smoke inlet channel by the channel-separating smoke pusher 20. The arranging belt 21 works in conjunction with the channel-separating smoke pusher 20, with each belt corresponding to a different smoke inlet channel, and the lifting smoke baffle 22 is used to control whether the cigarette boxes enter or exit the arranging belt 21.

[0050] Preferably, in this embodiment, the visual recognition device 19 is implemented using existing technology. The separate smoke pushing device 20 uses two oppositely arranged electric or pneumatic cylinders to push the cigarette boxes into different left and right smoke inlet channels for transport.

[0051] like Figure 4-7 As shown, this embodiment uses three sets of cigarette-supporting devices 2 as an example. The direct-draw cigarette stacking device receives cigarettes from the cooperating conveyor through the cigarette inlet 101. The cigarette boxes are confined into neat layers by the cooperation of the cigarette inlet 101 and the baffle 103. The baffle 103 also helps to limit the cigarette boxes, preventing them from being in the same position as the cigarette-supporting plate 201. The neatly arranged cigarette boxes are lifted by the cigarette-supporting plate 201. The cigarette-supporting device 2 opens the cigarette-supporting plate 201 sequentially from top to bottom, allowing the stacked cigarette boxes to gradually fall through the cigarette drop path until they land on the cigarette-receiving platform 10. The cigarette-receiving platform 10 moves up and down via a lifting device 11. In this embodiment, a servo lifting motor is used, but a cylinder can also be used. The cigarette stacking machine repeats the above steps to stack the cigarette boxes layer by layer, ultimately forming a standard rectangular cigarette box stack structure for the next packaging step. The lifting device 11 controls the horizontal height of the cigarette receiving platform 10 according to the number of stacked cigarette boxes. After all the cigarette boxes are stacked, the lifting device 11 controls the cigarette receiving platform 10 to reach the same horizontal plane as the transport platform 7. The transmission chain 8 drives the cigarette pusher 9 to move the stacked cigarette boxes on the transport platform 7 for subsequent packaging. The smoke baffle 12 is used to prevent the cigarette boxes from moving left and right during movement and causing the stacks to break apart.

[0052] Furthermore, to ensure stable operation of the cigarette holder 201, the fixing plate 203 is provided with one or more slide rails 204. Simultaneously, the linkage slider 4 for driving is also mounted on the slider slide rail 3. The linkage of multiple slide rails effectively improves the stability of the cigarette holder 201. A sliding groove 102 is also provided to facilitate the fixing of the cigarette holder 201 and the linkage slider 4. The driver 202 is a drive motor, which drives the drive belt 5 to control the linkage slider 4.

[0053] Furthermore, to simplify the mechanical structure, a single driver 202 is used to drive two linked sliders 4 in different directions simultaneously. A drive wheel 6 is provided, and the two drive wheels 6 cooperate with a drive belt 5. The two linked sliders 4 in the same group are respectively set on the first and second belt bodies of the drive belt 5. When the drive belt 5 rotates, the first and second belt bodies located at both ends of the drive wheel 6 will move in different directions, thereby driving the two linked sliders 4 to different positions, realizing the opening and closing function of the cigarette holder 201.

[0054] Preferably, the driver 202 can use a servo motor and a cylinder to drive the drive belt.

[0055] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
