Description

Technical Field

[0001] This invention relates to the field of cigarette packaging technology, specifically to a multi-inlet, single-outlet cigarette packaging device and method. Background Technology

[0002] As is well known, there are two main ways to push cigarette packs into the packaging box during the cigarette production process: the first is to push the filter end, and the second is to push the tobacco end.

[0003] With the increasing variety of cigarette packaging methods, higher requirements are being placed on cigarette packaging equipment. If the packaging method requires the equipment to push the tobacco end in, the tobacco end of the cigarette is easily damaged under external force at high speeds. This is especially true when pushing cigarette packs without aluminum foil inner lining, where the stress requirements on the cigarette packs are even higher.

[0004] Existing cigarette packaging equipment is divided into two packaging processes: single-path packaging and double-path packaging. The movement of the mold box is generally driven by a packaging conveyor belt or packaging wheels. The spacing between the mold boxes and the number of workstations are fixed values. Furthermore, during the packaging process, the frequency of pushing the cigarette group into the mold box and the frequency of outputting the cigarette pack are consistent, that is, single-in single-out or double-in double-out.

[0005] When cigarette production is carried out by pushing the tobacco ends, the faster the tobacco bundle is pushed, the more easily the tobacco bundle is deformed and damaged by the force, which in turn affects the packaging quality; while the slower the tobacco bundle is pushed, the slower the output speed of the cigarette pack, which in turn affects the packaging efficiency of the cigarettes.

[0006] Therefore, how to simultaneously ensure the efficiency and quality of cigarette packaging has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a multi-inlet single-outlet cigarette packaging device to solve the technical problem that existing cigarette packaging efficiency and packaging quality cannot be simultaneously achieved.

[0008] The technical solution adopted in this invention is: a multi-inlet single-outlet cigarette packaging device, comprising:

[0009] A circular track, along which are sequentially arranged paper-feeding station, smoke-inlet station, folding station and output station;

[0010] The template, wherein there are multiple templates, and the templates are connected to a circular track and can move intermittently along the circular track;

[0011] The paper-tapping board is set on the paper-tapping side of the circular track and can move the packaging paper in an L-shape into the mold box of the paper-tapping station.

[0012] The smoke pusher is located on the smoke inlet side of the circular track and can simultaneously push N parallel groups of cigarettes into N molds that are moved to the smoke inlet station.

[0013] A folding guide rail is provided on the folding side of the circular track and is capable of folding the packaging paper inside the mold box that has been moved to the folding station onto the outside of the cigarette assembly.

[0014] An output timing belt is provided, which is located on the smoke outlet side of the circular track and can remove the smoke packs from the mold box that has been moved to the output station one by one.

[0015] Where 2≤N.

[0016] Preferably, the annular track includes a magnetic drive guide motor, a coil track, and a mover. The coil track is connected to the magnetic drive guide motor. There are multiple movers, each corresponding to a mold box. The movers are connected to the coil track and can move cyclically along the coil track to drive the mold box to move intermittently along the coil track.

[0017] Preferably, the mold includes a support plate, side plates, and a connecting plate. The bottom end of the connecting plate is fixedly connected to the support plate, and the top end is fixedly connected to the mover. The two side plates are fixedly connected to the two sides of the support plate respectively to limit the position of the packaging paper. The support plate and the connecting plate are provided with clearance grooves that cooperate with the output synchronous belt, and the support plate is located below the mover.

[0018] Preferably, 2≤N≤4.

[0019] Preferably, N=3.

[0020] Preferably, the annular track includes straight segments and arc segments, and two straight segments and two arc segments are alternately arranged and connected end to end to form an oval track; the number of smoke inlet stations is N, and they are equally spaced on one of the straight segments; the number of output stations is one, and it is located on another straight segment.

[0021] Preferably, a detection station for detecting whether the cigarette pack inside the mold box has been moved out is provided between the output station and the paper-tapping station.

[0022] Preferably, a buffer station for extending the cigarette pack pushing time is provided between the paper-tapping station and the cigarette-feeding station, and the number of buffer stations is equal to the number of cigarette-feeding stations.

[0023] Preferably, the folding guide rail includes a holding rail, a pressing rail, a positioning rail, a clearance rail, and a folding rail. The holding rail extends from the paper-feeding station to the folding station in a parallel annular path, used to keep the front of the packaging paper vertical. The pressing rail is located at the folding station and downstream of the holding rail, used to press and fix the front of the packaging paper in a horizontal state. The positioning rail is located at the buffer station, used to vertically position the packaging paper. The clearance rail is located between the buffer station and the folding station, and below the cigarette pusher, used to press down the head of the packaging paper and avoid movement of the cigarette assembly. The folding rail is located between the pressing rail and the clearance rail, used to fold the packaging paper outside the cigarette assembly.

[0024] Another object of the present invention is to provide a multi-inlet, single-outlet cigarette packaging method, the method comprising the following steps:

[0025] S10: At the paper-feeding station, the packaging paper is sequentially fed into multiple mold boxes, and the mold boxes are moved to the buffer station; wherein, the packaging paper is L-shaped in the mold box;

[0026] S20: Simultaneously move the N molds of the buffer station to the smoke inlet station;

[0027] S30: The N cigarette sets are pushed one by one into the N mold boxes of the smoke inlet station in a synchronous manner by the smoke pusher;

[0028] S40: First, move the N mold boxes of the cigarette feeding station to the folding station in sequence, and then fold the packaging paper on the outside of the cigarette pack to form a cigarette pack;

[0029] S50: Move the cigarette packs from the folding station to the output station and remove them one by one from the mold box;

[0030] S60: Move the mold box from the output station to the testing station;

[0031] S70: Move the empty mold box of the testing station to the paper-feeding station.

[0032] The beneficial effects of this invention are:

[0033] This invention employs a multi-input, single-output method. Multiple intermittently moving molds are connected to the periphery of a circular track. These molds circulate between the paper-feeding station, the cigarette-feeding station, the folding station, and the output station. In conjunction with the cigarette pusher, multiple cigarette packs are pushed from the tobacco end into the packaging paper of the mold. At the folding station, the packaging paper is folded and wrapped around the outside of each cigarette pack. Finally, the formed cigarette packs are output one by one via a synchronous conveyor belt. This achieves asynchronous transport of cigarette packs and cigarette packs, greatly extending the cigarette pushing time, reducing the force on the tobacco end of the cigarette pack, and ensuring the packaging quality and efficiency of cigarettes.

[0034] This invention enables precise position control of a single mold box and allows for arbitrary arrangement and combination of multiple mold boxes. It achieves asynchronous cigarette insertion speed and cigarette pack output speed, significantly reducing the stress on the cigarette. Especially when pushing the tobacco end of the cigarette, it effectively reduces damage to the tobacco end of the cigarette while ensuring that the output speed of the cigarette pack does not decrease, thus improving packaging quality.

[0055] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0058] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0059] Examples, such as Figures 1-4 As shown, a multi-inlet single-outlet cigarette packaging device is used for pushing and packaging the tobacco ends of cigarette packs; the device includes:

[0060] A circular track 100 is provided with a paper-feeding station, a smoke-inlet station, a folding station, and an output station in sequence along the track direction of the circular track 100.

[0061] There are multiple mold boxes 200, and each mold box 200 is connected to the circular track 100 and can move intermittently in a circular motion along the trajectory direction of the circular track 100.

[0062] The paper-tapping board 300 is disposed on the paper-tapping side of the circular track 100, and the paper-tapping board 300 is capable of moving the packaging paper 700 in an L-shape into the mold box 200 of the paper-tapping station.

[0063] The smoke pusher 400 is located on the smoke inlet side of the circular track 100, and the smoke pusher 400 can push N parallel cigarette groups 800 one by one into the N mold boxes 200 that are moved to the smoke inlet station.

[0064] A folding guide rail 500 is provided on the folding side of the annular track 100, and the folding guide rail 500 is capable of folding the packaging paper 700 inside the mold box 200 that has been moved to the folding station onto the outside of the cigarette assembly 800.

[0065] The output timing belt 600 is set on the smoke outlet side of the circular track 100, and the output timing belt 600 can remove the smoke packs 900 one by one from the mold box 200 that has been moved to the output station.

[0066] Where 2≤N.

[0067] This application employs a multi-input, single-output method. Multiple intermittently movable mold boxes 200 are connected to the circumferential drive of the circular track 100. The mold boxes 200 can circulate between the paper-feeding station, the cigarette-feeding station, the folding station, and the output station. In conjunction with the cigarette pusher 400, multiple cigarette groups 800 are synchronously pushed from the tobacco end into the packaging paper 700 of the mold box 200. At the folding station, the packaging paper 700 is folded and packaged on the outside of each cigarette group 800. Finally, the formed cigarette packs 900 are output one by one through the output synchronous belt 600. This achieves asynchronous conveying of cigarette groups and cigarette packs, greatly extending the pushing time of the cigarette groups 800, reducing the force on the tobacco end of the cigarette groups 800, and thus ensuring the packaging quality and efficiency of cigarettes.

[0068] In one specific embodiment, such as Figure 1 As shown, the circular track 100 is a magnetically driven flexible transport system, which includes a magnetically driven guide rail motor 110, a coil track 120, and a mover 130. The coil track 120 is connected to the magnetically driven guide rail motor 110. There are multiple movers 130, which are connected to the mold box 200 one by one. The movers 130 are connected to the coil track 120 and can move cyclically along the coil track 120 to drive the mold box 200 to move intermittently along the coil track 120.

[0069] This configuration is based on the fact that magnetically driven flexible conveyor systems offer high control precision, high speed, and high flexibility. Applying them to cigarette packaging equipment significantly improves the flexibility of the cigarette packaging process, offering substantial advantages in reducing cigarette damage and enhancing packaging quality. Because the position of each individual mover 130 in the magnetically driven flexible conveyor system can be precisely controlled, the mold boxes 200 can be flexibly distributed, allowing the packaging process to break free from the limitations of traditional wheeled or belt conveyors. A mover group composed of multiple movers 130s, working in accordance with a reasonable motion pattern, can achieve variable interval and speed movement of the mold boxes 200, enabling flexible layout of cigarette feeding and discharging. This means that while maintaining a constant output speed for the cigarette pack 900, the feeding speed of the cigarette assembly 800 is reduced, thereby reducing the stress on the cigarette assembly 800, minimizing damage, and ultimately ensuring the packaging quality of the cigarettes.

[0070] In one specific embodiment, such as Figure 3 As shown, the mold 200 includes a support plate 210, side plates 220, and a connecting plate 230. The connecting plate 230 is L-shaped, and its bottom end is fixedly connected to one end of the support plate 210 along its length. The top end of the connecting plate 230 is detachably fixedly connected to the end of the mover 130 away from the coil track 120. There are two side plates 220, which are fixedly connected to both sides of the support plate 210 along its width to limit the packaging paper 700 in the width direction of the support plate 210. A clearance groove 240 that cooperates with the output synchronous belt 600 is provided in the middle of the support plate 210 and the connecting plate 230 along its length. The support plate 210 is located below the mover 130 so that the scraper 610 on the output synchronous belt 600 can pass through the clearance groove 240 and push out the cigarette pack 900 in the mold 200.

[0071] This is because one end of the mold box 200 along its length is fixedly connected to the mover 130 of the circular track 100, making it impossible to push the cigarette pack 900 in the mold box 200 to the output synchronous belt 600 at the output station via the push rod. In this embodiment, side plates 220 are vertically fixedly connected to both sides of the support plate 210 in the width direction. This can limit the packaging paper 700 in the moving direction of the mold box 200, so that the cigarette pusher 400 can accurately push the cigarette pack 800 onto the packaging paper 700 in the mold box 200, which facilitates the subsequent folding guide rail 500 to fold the packaging paper 700 on the outside of the cigarette pack 800. An avoidance groove 240 is provided in the middle of the support plate 210 and the connecting plate 230 along the length direction. When the output synchronous belt 600 rotates, the scraper 610 on the output synchronous belt 600 can pass through the avoidance groove 240 of the stationary mold box 200 and push out the cigarette pack 900 in the mold box 200, so as to realize the accurate output of the cigarette pack 900 at the output station.

[0072] It should be noted that the width direction of the support plate 210 is consistent with the moving direction of the mold box 200.

[0073] In one specific embodiment, 2 ≤ N ≤ 4.

[0074] This setup is because, under the premise that the output speed of the cigarette pack 900 remains constant, when the pushing speed of the cigarette assembly 800 is less than or equal to 1 / 2 of the output speed of the cigarette pack 900, the stress on the cigarette assembly 800 will be significantly improved; when the pushing speed of the cigarette assembly 800 is less than 1 / 4 of the output speed of the cigarette pack 900, more than four cigarette feeding stations need to be set on the circular track 100, which will lead to a sharp increase in the volume of the entire packaging device and occupy a large area of ​​the production workshop, affecting the overall cigarette production efficiency of the production workshop.

[0075] Preferably, N=3.

[0076] This design is because: there are three sets of cigarette pushers 400, which can simultaneously push three sets of arranged cigarette packs 800 into the mold box 200; the cigarette pushers 400 can contact the tobacco ends of the cigarette packs 800 for pushing; due to the process of pushing in three sets of cigarette packs 800 and outputting a single pack of cigarettes 900, the pushing speed of the cigarette packs 800 is one-third of the packaging speed, which can effectively reduce the force on the tobacco ends of the cigarette packs and ensure the quality of cigarette packaging.

[0077] In one specific embodiment, such as Figure 1 , Figure 2 As shown, the circular track 100 includes two straight segments and two circular arc segments, which are alternately arranged and connected end to end to form an oval track; there are N smoke inlet stations, which are equally spaced on one of the straight segments, that is, N smoke inlet stations are equally spaced on the straight segment on the smoke inlet side; there is one output station, which is set on the straight segment on the output side; the paperboard 300 is set at the top of the arc segment between the output station and the smoke inlet station; and the folding guide rail 500 is set on the entire arc segment between the smoke inlet station and the output station.

[0078] In one specific embodiment, such as Figure 2 As shown, a detection station is provided between the output station and the paper-tapping station to detect whether the cigarette pack inside the mold box 200 has been moved out.

[0079] Preferably, the number of testing stations is two.

[0080] In one specific embodiment, such as Figure 2 As shown, a buffer station is provided between the paper-feeding station and the cigarette-feeding station to extend the pushing time of the cigarette group 800, and the number of buffer stations is equal to the number of cigarette-feeding stations.

[0081] This setup is because, in this application, there is only one paper-feeding station. Therefore, the paper-feeding board 300 can only feed paper to N mold boxes 200 in the same group sequentially. However, when the mold boxes 200 move to the cigarette feeding station one by one after paper feeding, the waiting time for the cigarette pusher 400 will be too long, which is not conducive to reducing the pushing speed of the cigarette group 800. In this embodiment, after setting a buffer station between the paper-feeding station and the cigarette feeding station, the mold box 200 will move to the buffer station to wait after receiving the packaging paper 700 at the paper-feeding station. Then, after all the mold boxes 200 in the same group have received the packaging paper 700, they will move to the cigarette feeding station synchronously, realizing the synchronization of the cigarette feeding process and the paper-feeding process, indirectly extending the pushing time of the cigarette group 800, thereby ensuring the quality of cigarette packaging.

[0082] In one specific embodiment, such as Figure 1 As shown, the folding guide rail 500 includes a retaining rail 510, a pressing rail 520, a positioning rail 530, a clearance rail 540, and a folding rail 550. The retaining rail 510 is arranged parallel to the annular track 100 and extends from the paper-feeding station to the folding station, used to keep the front 710 of the packaging paper 700 vertical, so that the cigarette pusher 400 can push the cigarette assembly 800 into the packaging paper 700. The pressing rail 520 is located at the folding station, downstream of the retaining rail 510, used to press and fix the front 710 of the packaging paper 700 in a horizontal state. The positioning rail 530 is set at the buffer station, and the positioning rail 530 is provided with a limiting groove parallel to the annular rail 100 for vertical positioning of the packaging paper 700; the avoidance rail 540 is set between the buffer station and the folding station, and is located below the cigarette pusher 400, for pressing down the head 730 of the packaging paper 700 and avoiding the movement of the cigarette assembly 800, so that the cigarette pusher 400 can push the cigarette assembly 800 into the packaging paper 700; the folding rail 550 is set between the pressing rail 520 and the avoidance rail 540, for folding the packaging paper 700 on the outside of the cigarette assembly 800.

[0083] Specifically, positioning rail 530 and clearance rail 540 are installed on the outside of stations 1-7 to open the entrance of the packaging paper 700 that is fed into the mold box 200, so as to allow the subsequent cigarette pack 800 to be pushed in; holding rail 510 is installed above stations 2-12 to protect the front 710 (i.e., the vertical surface) of the L-shaped packaging paper 700, and presses down the vertical surface of the packaging paper 700 when it passes station 11 as the mold box 200 moves along the oval trajectory; folding rail 550 is installed on the outside of stations 7-13 to fold up the head 730 of the packaging paper 700 at the tobacco end when the mold box 200 passes; pressing rail 520 is installed above stations 13-16 to protect the packaged cigarette pack 900.

[0084] It should be noted that the specific structure of the folding rail 550 and the existing technology for folding the packaging paper 700 will not be described in detail again.

[0085] An embodiment of a multi-inlet, single-outlet cigarette packaging method includes the following steps:

[0086] S10: At the paper-feeding station, the packaging paper 700 is sequentially fed into multiple mold boxes 200, and the mold boxes 200 are moved to the buffer station; wherein, the packaging paper 700 is L-shaped in the mold box 200.

[0087] Specifically, along the trajectory of the circular track 100, one paper-feeding station, three buffer stations, three smoke-infeeding stations, eight folding stations, one output station, and two inspection stations are set up sequentially. Fifteen mold boxes 200 are connected to the outer side of the circular track 100 via a transmission system. The mold boxes 200 are divided into five groups of three. The three mold boxes 200 in the same group are moved to the paper-feeding station one after another. The mold box 200 receives the packaging paper 700 conveyed by the paper-feeding board 300 at the paper-feeding station. The packaging paper 700 is fixed in the mold box 200 in an L-shape. After receiving the packaging paper 700, the mold box 200 moves to the buffer station to wait for the next mold box 200 to perform the paper-feeding operation (the other groups of mold boxes 200 perform the smoke-infeeding operation at the same time).

[0088] S20: Simultaneously move the N mold boxes 200 from the buffer station to the smoke inlet station.

[0089] Specifically, when three mold boxes 200 of the same group are equally spaced on three buffer stations, the three mold boxes 200 are controlled to move synchronously to three empty smoke inlet stations.

[0090] S30: By pushing the smoke exhaust 400, N cigarette groups 800 are pushed one by one into the N mold boxes 200 of the smoke inlet station.

[0091] Specifically, the operation of the smoke pusher 400 is controlled, and the three parallel smoke stick groups 800 are pushed into the three mold boxes 200 of the three smoke inlet stations in a one-to-one correspondence.

[0092] S40: First, move the N mold boxes 200 from the cigarette feeding station to the folding station in sequence, and then fold the packaging paper 700 on the outside of the cigarette pack 800 to form a cigarette pack 900.

[0093] Specifically, the mold box 200, which has completed the cigarette feeding operation, is moved from the cigarette feeding station to the output station, and the packaging paper 700 is folded on the outside of the cigarette pack 800 at eight folding stations to form the cigarette pack 900.

[0094] S50: Move the cigarette packs 900 from the folding station to the output station and remove them one by one from the mold box 200.

[0095] Specifically, multiple cigarette packs 900 are intermittently moved from the folding station to the output station, and the cigarette packs 900 in the mold box 200 that have moved to the output station are output one by one by the scraper 610 on the output timing belt 600, and the conveying direction of the output timing belt 900 is perpendicular to the circular track 100.

[0096] S60: Move the mold 200 from the output station to the inspection station.

[0097] S70: Move the empty mold box 200 from the inspection station to the paper-feeding station.

[0098] Specific embodiment 1: A three-inlet single-outlet cigarette packaging method, the method includes the following steps:

[0099] Fifteen mold boxes 200 move in a circular motion along the waist-shaped trajectory. Stations 1-18 are arranged non-uniformly along the circumference of the waist-shaped trajectory. Station 1 is located at the top of the waist-shaped arc segment. At station 1, the mold box 200 is aligned with the tapping board 300. The tapping board 300 taps the packaging paper 700 down, and the packaging paper 700 forms an L-shape in the mold box 200, with the opening of the packaging paper 700 facing outward from the trajectory.

[0100] After receiving the packaging paper 700 at station 1, the three mold boxes 200 in the same group move clockwise to station 2, station 3 and station 4 located on the oval trajectory and stop to wait. The movement speed of each mold box 200 is not equal.

[0101] Then the three mold boxes 200 with packaging paper 700 move to the straight section of the oval trajectory at stations 5, 6 and 7, align with the smoke pusher 400 and stop to wait for smoke to enter.

[0102] The three sets of tobacco pushers 400 move horizontally, simultaneously pushing the three sets of arranged tobacco sticks 800 into the three mold boxes 200 located at workstations 5, 6 and 7. The tobacco pushers 400 contact the tobacco ends of the tobacco sticks 800.

[0103] After the cigarette pack 800 is pushed out, the mold boxes 200 at stations 5, 6 and 7 move clockwise along the arc segment of the oval trajectory, causing the folded edges of the packaging paper 700 to be folded at stations 8, 9, 10 and 11 by the action of the holding rail 510 and the folding rail 550. The folded cigarette pack 900 is then moved to station 16 by the pressing rail 520 under the action of the mold box 200 and stops to wait.

[0104] At station 16, the output synchronous belt 600 is set along the vertical circular track 100 and is driven by an independent servo motor, which can move continuously and is precisely matched with the phase of the mover 130. Scrapers 610 are evenly arranged on the output synchronous belt 600. When the mold box 200 moves to station 16 and stops, the scrapers 610 can scrape out the cigarette packs 900 that have moved to station 16 one by one. In addition, the output synchronous belt 600 can reduce the stopping time of the mold box 200 by changing its speed, thereby improving the packaging speed.

[0105] Empty station detectors are installed at workstations 17 and 18. When the cigarette packs inside the mold box 200 are not scraped out, the detector signal is blocked, and the equipment will stop and alarm to empty the mold box 200. If the mold box 200 is empty, the detector receives the signal, and the mold box 200 enters workstation 1 for the next packaging cycle.

[0106] Compared with the prior art, this application has at least the following beneficial technical effects:

[0107] This application adopts a three-way inlet and single-way outlet packaging method. Each time, three sets of cigarettes are pushed out, and the cigarette pack output action is performed three times in succession. Under the condition that the tobacco end of the cigarette set needs to be pushed out and the cigarette set is not wrapped with aluminum foil inner lining paper, the cigarette pack output speed is reduced to one-third of the cigarette pack output speed without reducing the cigarette push speed. This greatly reduces the cigarette set push speed, reduces the force on the tobacco end of the cigarette, thereby reducing cigarette damage and ensuring the packaging quality and packaging efficiency of the cigarette.

[0108] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
