Description

Technical Field

[0001] This invention relates to the field of cigarette packing technology, specifically to a method for packing cigarette packs into boxes to accommodate various specifications and styles. Background Technology

[0002] There are various cigarette pack packaging machines on the market. Single-layer carton types include side-opening single-layer cartons and double-opening single-layer cartons. Publication number CN115571437A describes a cigarette packaging filling line for the production of side-opening single-layer cartons, and authorization announcement number CN212710401U describes an automated filling production line for forming packaging boxes for the production of double-opening single-layer cartons. Currently, each production line is only designed for packaging one type of carton, and the specifications and dimensions of the carton cannot change. In this era of rapid product updates, this leads to increased costs for cigarette factories to upgrade their products. Summary of the Invention

[0003] To address the problems in the existing technology, the present invention provides a packaging method for cigarette packs that can be adapted to various specifications and styles. The purpose is to package side-opening single-layer cartons and double-opening single-layer cartons of different specifications, thereby reducing the production costs required for product replacement or upgrade.

[0004] A method for packaging cigarette packs of various specifications and styles includes a carton supply station 1b, a lid opening station 2b, a cigarette pack insertion station 4b, a lid closing station 6b, and a discharge station 8b. A carton transfer mechanism 7 is provided between each station to transfer the cartons between each station. A carton shifting and holding mechanism is provided at each station to move the cartons at the station from the carton transfer mechanism 7 into the corresponding packaging area, and also to place the cartons that have completed the corresponding packaging process from the packaging area onto the carton transfer mechanism 7 at the corresponding station.

[0005] The carton packaging method includes the following steps:

[0006] Step 1: After receiving the carton from the carton supply system 1a, the carton shifting and holding mechanism at carton supply station 1b places the carton onto the carton transfer mechanism 7 at carton supply station 1b.

[0007] Step 2: After receiving the carton from the carton supply station 1b, the carton shifting and holding mechanism at the opening station 2b opens the lid of the single-layer carton by means of the double-opening opening mechanism 1 when the carton is a split-type single-layer carton, and then places the carton back onto the carton transfer mechanism 7 at the opening station 2b; when the carton is a side-opening single-layer carton, it opens the lid of the side-opening single-layer carton by means of the side-opening opening mechanism 2, and then places the carton back onto the carton transfer mechanism 7 at the opening station 2b.

[0008] Step 3: After receiving the carton from the opening station 2b, the carton shifting and holding mechanism at the cigarette pack loading station 4b places the cigarette pack inside the carton through the cigarette pack loading system, and then puts the carton back onto the carton transfer mechanism 7 at the cigarette pack loading station 4b.

[0009] Step 4: After receiving the carton from the packing station 4b, the carton shifting and holding mechanism at the capping station 6b closes the lid of the single-layer carton (opening in half) through the first capping mechanism 4a, and then places the carton on the carton transfer mechanism 7 at the return capping station. When the carton is a single-layer carton (opening to the side), the lid of the single-layer carton (opening to the side) is closed through the second capping mechanism 5, and then the carton is placed on the carton transfer mechanism 7 at the return capping station.

[0010] Step 5: After receiving the carton from the closing station 6b, the carton shifting and holding mechanism at the discharge station 8b discharges the carton through the unloading mechanism 5a.

[0011] The beneficial effects of this invention are as follows: By setting up a carton transfer mechanism between each workstation and a carton shifting and holding mechanism at each workstation, the carton can stay and transfer between adjacent workstations. In conjunction with the split-opening mechanism, the side-opening mechanism, the cigarette pack box insertion system, the first closing mechanism, and the second closing mechanism, the packaging production of different batches of split-opening single-layer cartons and side-opening single-layer cartons can be realized, thereby reducing the production cost of manufacturers.

[0025] The present invention will now be described in detail with reference to the accompanying drawings. Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. The directional terms such as left, center, right, top, and bottom in the embodiments of the present invention are only relative concepts or referenced to the normal use state of the product, and should not be considered restrictive.

[0026] First embodiment:

[0027] A method for packaging cigarette packs into boxes that adapts to various specifications and styles, combined with... Figures 1 to 3 As shown, the system includes a carton supply station 1b, a lid opening station 2b, a cigarette pack loading station 4b, a lid closing station 6b, and a discharge station 8b. A carton transfer mechanism 7 is provided between each station to transfer the cartons between each station. A carton shifting and holding mechanism is provided at each station to move the cartons at the station from the carton transfer mechanism 7 into the corresponding packaging area, and also to place the cartons that have completed the corresponding packaging process from the packaging area onto the carton transfer mechanism 7 at the corresponding station.

[0028] The carton packaging method includes the following steps:

[0029] Step 1: After receiving the carton from the carton supply system 1a, the carton shifting and holding mechanism at carton supply station 1b places the carton onto the carton transfer mechanism 7 at carton supply station 1b.

[0030] Step 2: After receiving the carton from the carton supply station 1b, the carton shifting and holding mechanism at the opening station 2b opens the lid of the single-layer carton by means of the double-opening opening mechanism 1 when the carton is a split-type single-layer carton, and then places the carton back onto the carton transfer mechanism 7 at the opening station 2b; when the carton is a side-opening single-layer carton, it opens the lid of the side-opening single-layer carton by means of the side-opening opening mechanism 2, and then places the carton back onto the carton transfer mechanism 7 at the opening station 2b.

[0031] Step 3: After receiving the carton from the opening station 2b, the carton shifting and holding mechanism at the cigarette pack loading station 4b places the cigarette pack inside the carton through the cigarette pack loading system, and then puts the carton back onto the carton transfer mechanism 7 at the cigarette pack loading station 4b.

[0032] Step 4: After receiving the carton from the packing station 4b, the carton shifting and holding mechanism at the capping station 6b closes the lid of the single-layer carton (opening in half) through the first capping mechanism 4a, and then places the carton on the carton transfer mechanism 7 at the return capping station. When the carton is a single-layer carton (opening to the side), the lid of the single-layer carton (opening to the side) is closed through the second capping mechanism 5, and then the carton is placed on the carton transfer mechanism 7 at the return capping station.

[0033] Step 5: After receiving the carton from the closing station 6b, the carton shifting and holding mechanism at the discharge station 8b discharges the carton through the unloading mechanism 5a.

[0034] Second embodiment:

[0035] Other technical features are as follows: In the same manner as the first embodiment, when a carton contains a laminated paper, a laminated paper opening station 3b is provided between the opening station 2b and the cigarette pack insertion station 4b. The carton shifting and holding mechanism at the laminated paper opening station 3b receives the carton from the opening station 2b and, through the laminated paper opening mechanism 8, removes the laminated paper from the carton, then places the carton back onto the carton transfer mechanism 7 at the laminated paper opening station 3b. Correspondingly, the carton shifting and holding mechanism at the cigarette pack insertion station 4b receives the carton indirectly from the opening station 2b, i.e., receives the carton directly from the laminated paper opening station 3b. Figure 8 As shown, the laminated paper opening mechanism 8 includes a sixth linear module 82 and a second electric telescopic cylinder 83. The sixth linear module 82 spans above the linear motor 7 and is arranged perpendicularly to it. The second electric telescopic cylinder 83 is fixedly connected to the slide of the sixth linear module 82 and is arranged vertically. A third suction cup 81 for adsorbing the laminated paper is fixedly installed at the top of the telescopic rod of the second electric telescopic cylinder 83. When it is necessary to flip the laminated paper out of the box, the telescopic rod of the second electric telescopic cylinder 83 extends downward and makes the third suction cup 81 engage with the set position of the laminated paper. Then the telescopic rod rises and the sixth linear module 82 drives the laminated paper to flip, thereby flipping the laminated paper out of the box. The first suction cup 15, the second suction cup 25 and the third suction cup 81 are all flared rubber suction cups.

[0036] A laminating paper resetting station 5b is provided between the cigarette pack loading station 4b and the lid closing station 6b. The carton shifting and holding mechanism at the laminating paper resetting station 5b receives the carton from the cigarette pack loading station 4b, and then resets the laminating paper into the carton via the laminating paper resetting mechanism 6. The carton is then placed back onto the carton transfer mechanism 7 at the laminating paper resetting station 5b. Correspondingly, the carton shifting and holding mechanism at the lid closing station 6b receives the carton indirectly from the cigarette pack loading station 4b, that is, it receives the carton directly from the laminating paper resetting station 5b. Figure 9As shown, the laminated paper resetting mechanism 6 includes a seventh linear module 62 and a fourth servo motor 61. The seventh linear module 62 spans above and is perpendicular to the linear motor 7. The fourth servo motor 61 is fixedly connected to the slide of the seventh linear module 62 via a mounting base 64. The fourth servo motor 61 is located below and perpendicular to the seventh linear module 62. A third swing arm 63 is fixedly connected to the drive shaft of the fourth servo motor 61 and is perpendicular to it. The fixed end of the third swing arm 63 is fixedly connected to the drive shaft of the fourth servo motor 61. A pneumatic telescopic cylinder 62 is fixedly connected to the free end of the third swing arm 63. The telescopic rod of the pneumatic telescopic cylinder 62 is parallel to the drive shaft of the fourth servo motor 61. When it is necessary to flip the laminated paper into the carton, the telescopic rod of the pneumatic telescopic cylinder 62 extends and passes under a specific position of the laminated paper. The fourth servo motor 61 drives the pneumatic telescopic cylinder 62 to swing, and at the same time, the seventh linear module 62 drives the laminated paper to flip into the carton.

[0037] Third embodiment:

[0038] Other technical features are the same as in the first embodiment, such as... Figure 2 As shown, when a label needs to be affixed to the carton, a labeling station 7b is provided between the closing station 6b and the discharging station 8b. The carton shifting and holding mechanism at the labeling station 7b receives the carton from the closing station, affixes the label to the carton using a labeling machine, and then places the carton back onto the carton transfer mechanism 7 at the labeling station 7b. Correspondingly, the carton shifting and holding mechanism at the discharging station 8b receives the carton indirectly from the closing station 6b, that is, it receives the carton directly from the labeling station 7b.

[0039] Specifically:

[0040] The carton transfer mechanism 7 includes a linear guide rail 71 and several seats 72 that are movably mounted on the linear guide rail 71. The carton supply station 1b, the lid opening station 2b, the cigarette pack loading station 4b, the lid closing station 6b, and the discharge station 8b are distributed sequentially from front to back along the linear guide rail 71.

[0041] Combination Figure 4As shown, the carton shifting and holding mechanism is a carton lifting support 9. The carton lifting support 9 includes two support platforms 91 that are synchronously raised and lowered. These two support platforms 91 are located on the left and right sides of the carton transfer mechanism, respectively. Positioning devices 90 for positioning the carton are provided on both the base body 72 and the support platforms 91. When the support platform 91 descends, it transfers the carton on the support platform 91 to the corresponding base body. The base body supports the carton and transfers it to the next work station. The support platform at this work station rises and lifts the carton on the base body to a set position, which is the packaging area. The carton lifting support 9 also includes a horizontal connecting plate 93 and a first electric telescopic cylinder 92. The horizontal connecting plate 93 is horizontally arranged below the linear motor 7. The two ends of the horizontal connecting plate 93 are fixedly connected to the bottom of the two support platforms 91, respectively. The telescopic rod of the first electric telescopic cylinder 92 is vertically arranged and fixedly connected to the middle of the horizontal connecting plate 93, thereby driving the horizontal connecting plate 93 to move up and down. A support 94 is provided below the transverse connecting plate 93. The cylinder body of the first electric telescopic cylinder 92 is fixedly connected to the support 94. The telescopic rod of the first electric telescopic cylinder 92 passes through the support 94 and is clearance-fitted with it. Vertical guide rods 96 are fixed at both ends of the transverse connecting plate 93. The guide rods 96 pass through the support 94 and are slidably fitted with it. A limit block 95 is provided on the support platform 91 located at the carton supply station 1b. The limit block 95 is located on the rear side of the top surface of the support platform 91 and is used to limit the position of the carton on the support platform 91. The positioning device 90 is a suction cup structure, which includes a rubber pad 901 vulcanized to the top surface of the support platform 91 and the top surface of the seat 72. Negative pressure grooves 902 are distributed on the rubber pad 901. Gas channels communicating with the corresponding negative pressure grooves 902 are provided in the support platform 91 and the seat 72. The surface of the rubber pad 901 is smooth, and its surface roughness can be set to less than 1.6. After the gas channels draw in air, a negative pressure is generated in the negative pressure grooves 902, thereby adsorbing the strip box on the support platform 91 or the seat 72. Simultaneously, the surface roughness of the rubber pad 901 must be maintained to ensure the adsorption effect.

[0042] A support 100 is provided above the carton transfer mechanism 7. A split-opening mechanism 1 and a side-opening mechanism 2 are independently and vertically mounted on the support 100, located on the front and rear sides of the opening station 2b, respectively. A first closing mechanism 4a is provided on the left and right sides of the closing station 6b, and a second closing mechanism 5 is provided at the closing station 6b. Figure 5As shown, the split-opening mechanism 1 includes a vertically arranged first linear module 11. The body of the first linear module 11 is fixedly connected to the bracket 100. A vertical first fixing plate 12 is fixedly mounted on the slide of the first linear module 11. The surface of the first fixing plate 12 is perpendicular to the transmission direction of the carton transfer mechanism 7. First servo motors 16 are fixedly connected to the left and right sides of the first fixing plate 12. The drive shafts of the first servo motors 16 are parallel to the transmission direction of the carton transfer mechanism 7. A first swing arm 13 is fixedly mounted on the moving shaft. A first mounting rod 14 is fixedly connected to the free end of the first swing arm 13. The first mounting rod 14 is perpendicular to the surface of the first fixed plate 12 and located on the side of the first swing arm 13 away from the first fixed plate 12. First suction cups 15 for adsorbing the lid of a split single-layer box are distributed on the first mounting rod 14. The first servo motor 16, the first swing arm 13, the first mounting rod 14, and the first suction cups 15 constitute a flip-top assembly. The two flip-top assemblies are symmetrically arranged about the center line of the first linear module 11. Figure 11 As shown, the first servo motor 16 drives the first swing arm 13 to swing, causing the first suction cup 15 to contact and adhere to the lid of the split single-layer carton. The first suction cups 15 on the two first mounting rods 14 respectively adhere to the two lids of the split single-layer carton. After the first swing arm 13 rotates in the opposite direction, the two lids of the split single-layer carton move away from each other and complete the opening. Then the first suction cup 15 releases air and separates from the lid.

[0043] Combination Figure 6 As shown, the side-opening lid mechanism 2 includes a second linear module 26, a second servo motor 24, and a U-shaped connecting seat 21 with the opening facing downwards. The second linear module 26 is fixedly connected to the bracket 100 and located directly above the carton transfer mechanism 7. The U-shaped connecting seat 21 is fixedly connected to the slide of the second linear module 26. Second swing arms 23 are symmetrically arranged at both ends of the U-shaped connecting seat 21. A crossbar 22 is fixedly connected between the free ends of the second swing arms 23. Second suction cups 25 for adsorbing the side-opening single-layer carton lid are distributed on the crossbar 22. The connecting ends of the second swing arms 23 are rotatably mounted on the U-shaped connecting seat 21 and driven by the second servo motor 24. Figure 12 As shown, the second servo motor 24 drives the first swing arm 13 to swing, and causes the second suction cup 25 to contact and adhere to the lid of the side-opening single-layer carton. Then, after the second swing arm 23 rotates in the opposite direction, the lid of the side-opening single-layer carton is opened. After that, the second suction cup 25 releases air and separates from the lid.

[0044] Combination Figure 7As shown, the cigarette pack loading system is fixed on the bracket 100 and located above the cigarette pack loading station 4b. The cigarette pack loading system includes a cigarette pack loading mechanism 3, a cigarette pack pushing mechanism 4, and a cigarette pack supply line 2a. The cigarette pack loading mechanism 3 includes a third linear module 31, a fourth linear module 32, a guide plate frame 35, and a pressing push plate 34. The guide plate frame 35 and the pressing push plate 34 are both disclosed in the prior art by CN212244003U (a cigarette pack loading guide device) and CN212244002U (a cigarette pack loading pressing device). The third linear module 31 is fixedly connected to the bracket 100 and Located directly above the carton transfer mechanism 7, a vertical second fixing plate 37 is fixedly connected to the slide of the third linear module 31. The guide plate frame 35 is provided with an infeeding station for guiding cigarette packs into the carton. The downward push plate 34 is located directly above the guide plate frame 35 and directly opposite the infeeding station. The downward push plate 34 is fixedly connected to the slide of the fourth linear module 32 via a vertical connecting plate 33. The fourth linear module 32 is fixedly connected to the second fixing plate 37. The rotating shaft in the guide plate frame 35 is driven by a third servo motor 36 fixedly installed on the second fixing plate 37.

[0045] The cigarette pack pushing mechanism 4 includes a cigarette pusher plate 44, a cigarette pusher plate flat pushing mechanism, and a cigarette pusher plate flipping mechanism 43. Both the cigarette pusher plate 44 and the cigarette pusher plate flipping mechanism 43 are existing technologies and are disclosed in CN114802905A, a cigarette pack pushing mechanism. The cigarette pusher plate 44 is located on one side of the cigarette pack conveyor belt of the cigarette pack supply line 2a. The cigarette pusher plate flat pushing mechanism drives the cigarette pusher plate 44 to reciprocate horizontally, pushing the cigarette packs on the conveyor belt out and onto the box-entry station of the guide plate frame 35. During the reset process of the cigarette pusher plate 44, the cigarette pusher plate flipping mechanism 43 first moves the cigarette pusher plate 44... 4. The pusher plate 44 flips upward to avoid the cigarette packs on the conveyor belt. After passing over the cigarette pack conveyor belt, the pusher plate 44 flips back to its original position. The pusher plate flat pushing mechanism includes a mounting frame 42 and a fifth linear module 41. The fifth linear module 41 is located above the cigarette pack conveyor belt and is arranged along the moving direction of the pusher plate 44. The mounting frame 42 is fixedly connected to the slide of the fifth linear module 41. The pusher plate flipping mechanism 43 is fixedly installed on the lower part of the mounting frame 42, and the pusher plate 44 is installed on the pusher plate flipping mechanism 43.

[0046] like Figure 2 As shown, the first closing mechanism 4a is a guide rod for guiding the closing of the lid of the split single-layer box. This guide rod is disclosed in CN212710401U - An automated filling production line for molded packaging boxes, as... Figure 10As shown, the second lid-closing mechanism 5 includes two synchronously lifting rods 51. These two rods 51 are arranged side by side and located in front of the lid-closing station 6b. The two rods 51 are located on the left and right sides of the carton transfer mechanism, respectively, and are used to quickly lift the lid of the side-opening carton in front of it and close it by flipping the lid over. A roller 53 is rotatably mounted on the top end of the rod 51. A support plate 52 is fixedly provided on the top of the rod away from the lid-closing station 6b. The support plate 52 is inclined, and its lower end is fixedly connected to the end of the rod 51. The upper end of the support plate 52 extends away from the lid-closing station 6b and is higher than the roller 53. The upper end of the support plate 52 is bent downward to avoid damaging the surface of the lid.
