Description

Technical Field

[0001] This invention belongs to the field of tobacco machinery technology, specifically relating to a full-surface oil sealing device for irregularly shaped packaging boxes and its working method. Background Technology

[0002] Currently, the most common cigarette packaging on the market consists of two types: rectangular paper boxes and cylindrical metal boxes. Cigarette sticks are also mostly cylindrical with a uniform diameter from top to bottom, and cigarette packaging is generally designed accordingly. However, with advancements in cigarette manufacturing technology, unconventional cigarette sticks have emerged, such as those with a cylindrical filter and a square tobacco section. A standard cigarette pack requires a rectangular box, while irregularly shaped cigarette packs, due to their varying volumes, require a trapezoidal box that is wider at the top and narrower at the bottom. If a standard cigarette box is used to accommodate irregularly shaped cigarette packs, the packs will inevitably be cramped at the top and loose at the bottom, creating narrow gaps. This can lead to instability during storage and transportation, causing the cigarettes to be squeezed and deformed, and the tobacco to scatter. Therefore, standard cigarette box designs cannot meet the packaging requirements of irregularly shaped cigarette sticks. Custom-designed boxes are needed based on the specific shape and volume of the irregularly shaped cigarettes and cigarette packs, such as the irregularly shaped packaging box disclosed in CN11766913U.

[0003] However, how to achieve the film coating of the aforementioned irregularly shaped packaging boxes is a problem. To solve this problem, this invention is proposed. Summary of the Invention

[0004] The first aspect of the present invention provides a full-surface oil sealing device for irregularly shaped packaging boxes, the irregularly shaped packaging boxes including: cigarette box outer box;

[0005] The right side 08 of the cigarette box is square and the left side 09 is regular octagon.

[0006] The outer sidewall of the cigarette box slopes from the four corners of its right side 08 toward the left side 09 to form four triangular first sidewalls 06, and the remaining part forms four trapezoidal second sidewalls 07 that intersect with the first sidewalls 06.

[0007] The cigarette pack oil sealing device includes: a cigarette pack initial oil sealing device 6 and a control mechanism;

[0008] The cigarette pack full-surface initial oil sealing device 6 includes:

[0009] Three sets of single-axis cigarette pack right side pneumatic initial oil sealing mechanisms 6.1 are used to achieve the initial oil sealing of the packaging film 00 on the lower right side area 081, the left side area 083 and the right side area 084 of the irregular packaging box.

[0010] A set of dual-axis cigarette pack right side pneumatic initial oil sealing mechanism 6.2, which is used to achieve the initial oil sealing of the packaging film 00 on the upper part of the right side surface 082 of the irregular packaging box;

[0011] A set of pneumatic initial oil sealing mechanism 6.3 on the side of the cigarette pack is used to wrap and initially seal the top rear side 010 of the irregularly shaped packaging box with the packaging film 00;

[0012] A set of pneumatic initial oil sealing mechanisms 6.4 on the front side of the cigarette pack is used to wrap and initially seal the front side 011 of the top of the irregularly shaped packaging box with the packaging film 00.

[0013] Each of the above-mentioned oil sealing mechanisms is equipped with an oil sealing plate for oil sealing;

[0014] The control mechanism is used to realize the movement of the above-mentioned oil seal mechanisms.

[0015] Preferably, the cigarette pack oil sealing device further includes: a cigarette pack final oil seal output device 7;

[0016] The cigarette pack full-surface final oil seal output device 7 includes:

[0017] The initial oil sealing mechanism 7.1 at the left end of the cigarette pack is used to achieve the initial oil sealing of the packaging film 00 on the left side 09 of the irregularly shaped packaging box;

[0018] Four sets of pneumatic final oil sealing mechanisms 7.2 on the sides of the cigarette pack are used to achieve final oil sealing of the packaging film 00 on the four sides of the irregularly shaped packaging box;

[0019] A set of pneumatic final oil sealing mechanism 7.3 on the left side of the cigarette pack end face is used to achieve the final oil seal of the packaging film 00 on the left side 09 of the irregular packaging box;

[0020] A set of pneumatic final oil sealing mechanism 7.4 on the right side of the cigarette pack end face is used to achieve the final oil seal of the packaging film 00 on the right side 08 of the irregular packaging box;

[0021] The pneumatic push-out slide 7.6 for cigarette packs is used to push the cigarette packs between the left pneumatic final oil sealing mechanism 7.3 and the right pneumatic final oil sealing mechanism 7.4 of the cigarette pack end face to perform final oil sealing on the left side 09 and right side 08 of the irregularly shaped packaging box;

[0022] Each of the above-mentioned oil sealing mechanisms is equipped with an oil sealing plate for oil sealing.

[0023] Preferably, the initial oil sealing mechanism 7.1 at the left end of the cigarette pack includes: a rotatable drive gear 7.1.3.2 and a rotatable rotating gear 7.1.10;

[0024] The drive gear disk 7.1.3.2 and the rotating gear disk 7.1.10 both have the same and overlapping circular openings at their centers, which are used for inserting the packaging film 00 portion on the left side 09 of the irregularly shaped packaging box that has not yet been sealed with oil.

[0025] The rotating gear disk 7.1.10 has eight left-side octagonal initial oil seal assemblies 7.1.1 arranged circumferentially around its circular opening. Each left-side octagonal initial oil seal assembly 7.1.1 has a triangular hot plate 7.1.1.1. The drive gear disk 7.1.3.2 has eight slotted openings 7.1.3.1 arranged circumferentially around the circular opening. Each left-side octagonal initial oil seal assembly 7.1.1 is connected to each of the eight slotted openings 7.1.3.1 through a bearing 7.1.11. Each left-side octagonal initial oil seal assembly 7.1.1 can slide along a radial slide rail 7.1.12, which is fixed along the radial direction of the rotating gear disk 7.1.10.

[0026] Preferably, the cigarette pack initial oil sealing device 6 further includes: a cigarette pack pneumatic lifting and positioning mechanism 6.5, and a cigarette pack pneumatic ejection mechanism 6.6;

[0027] The pneumatic lifting and positioning mechanism 6.5 for cigarette packs is used to receive and position the irregularly shaped packaging box and packaging film 00 transmitted from the aforementioned workstation.

[0028] The pneumatic ejection mechanism 6.6 of the cigarette pack is used to eject the irregularly shaped packaging box that has completed the initial oil seal and convey it to the cigarette pack final oil seal output device 7.

[0029] A second aspect of the present invention provides a method for operating the full-surface oil sealing device for irregularly shaped packaging boxes described in the first aspect, comprising the following steps:

[0030] The control mechanism controls three sets of single-axis cigarette pack right side pneumatic initial oil sealing mechanisms 6.1 to achieve the initial oil sealing of the packaging film 00 on the lower right side area 081, the left side area 083, and the right side area 084 of the irregular packaging box.

[0031] The control mechanism controls the pneumatic initial oil sealing mechanism 6.2 at the right end of the dual-axis cigarette pack to achieve the initial oil sealing of the packaging film 00 on the upper part of the right side surface 082 of the irregularly shaped packaging box;

[0032] The control mechanism controls the pneumatic initial oil sealing mechanism 6.3 on the side of the cigarette pack to achieve the wrapping and initial oil sealing of the packaging film 00 on the top rear side 010 of the irregularly shaped packaging box;

[0033] The control mechanism controls the pneumatic initial oil sealing mechanism 6.4 on the front side of the cigarette pack to achieve the wrapping and initial oil sealing of the packaging film 00 on the front side 011 of the top of the irregularly shaped packaging box.

[0034] Preferably, the specific operation of initial oil sealing on the left side 09 of the irregularly shaped packaging box is as follows:

[0035] 1. In the initial state, the eight heating plates 7.1.1.1 are in the open state;

[0036] 2. The cigarette pack final oil seal output device 7 moves horizontally towards the cigarette pack, so that the unsealed packaging film 00 on the left side 09 of the irregularly shaped packaging box passes through the circular opening in the center of the drive gear plate 7.1.3.2 and the rotating gear plate 7.1.10;

[0037] 3. The drive gear 7.1.3.2 rotates and drives the slot 7.1.3.1 to rotate. The rotating gear 7.1.10 remains stationary. The left octagonal initial oil seal assembly 7.1.1 moves inward along the radial slide rail 7.1.12 under the constraint of the slot 7.1.3.1, realizing the synchronous closing of the eight heating plates 7.1.1.1. Then the heating plates 7.1.1.1 cause the unsealed packaging film 00 part to adhere to the left side 09 of the cigarette pack, realizing a uniform vertical initial oil seal on the left side 09 of the cigarette pack.

[0038] 4. After the initial vertical oil seal is completed, the drive gear 7.1.3.2 rotates in the opposite direction, driving the eight heating plates 7.1.1.1 to open a certain distance from the closed state, ensuring that the octagonal corners will not tear when rotated and flattened. Then, the rotating gear 7.1.10 rotates, causing the eight heating plates 7.1.1.1 to rotate, rotating and flattening the packaging film that has completed the initial vertical seal in the same direction, thus achieving the initial oil seal of the octagonal corners on the left side 09 of the irregularly shaped packaging box.

[0039] The above technical solutions can be freely combined, provided they do not contradict each other.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. This application provides a full-surface oil sealing device for irregularly shaped packaging boxes, which can solve the problem that it is difficult to use conventional cubic packaging box devices for wrapping and full-surface oil sealing when the bottom surface of the irregularly shaped packaging box is square and the top surface is regular octagonal.

[0042] 2. In the preferred technical solution, this application achieves the initial oil seal on the octagonal left side of the cigarette pack by designing a rotating gear disk 7.1.10 and a driving gear disk 7.1.3.2. Attached Figure Description

[0064] Figure 7 The image shows an irregularly shaped packaging box to be coated according to this application, such as the irregularly shaped packaging box disclosed in CN11766913U. Because the irregularly shaped packaging box is placed horizontally during coating, its structure will be described using the horizontally placed irregularly shaped packaging box as an example.

[0065] The irregularly shaped packaging box includes: cigarette box outer box 05;

[0066] The right side 08 of the outer box 05 of the cigarette box is square and the left side 09 is regular octagon;

[0067] The outer wall of the cigarette box 05 slopes from the four corners of its right side 08 toward the left side 09 to form four triangular first side walls 06, and the remaining part forms four trapezoidal second side walls 07 that intersect with the first side walls 06.

[0068] like Figure 1 As shown, the cigarette pack full-surface initial oil sealing device 6 mainly consists of three sets of single-axis pneumatic initial oil sealing mechanisms 6.1 at the right end of the cigarette pack, one set of double-axis pneumatic initial oil sealing mechanisms 6.2 at the right end of the cigarette pack, one set of pneumatic initial oil sealing mechanisms 6.3 at the rear side of the cigarette pack, one set of pneumatic initial oil sealing mechanisms 6.4 at the front side of the cigarette pack, a pneumatic lifting and positioning mechanism for the cigarette pack, a pneumatic ejection mechanism for the cigarette pack, a valve island 6.7, and a mounting frame 6.8.

[0069] Each of the aforementioned oil-sealing mechanisms is equipped with an oil-sealing heating plate, a heating element, and a temperature sensor. The sequential extension and retraction of each group of cylinders, controlled by a program, automatically completes the wrapping of each side of the cigarette pack. The initial oil sealing and pneumatic lifting and positioning mechanism 6.5 receives and positions the irregularly shaped packaging box and packaging film 00 (i.e., BOPP film) conveyed from the aforementioned workstations. The pneumatic ejection mechanism 6.6 ejects the irregularly shaped packaging box that has completed the initial oil sealing and conveys it to the final oil sealing output device 7.

[0070] The initial oil sealing device 6 for the entire surface of the cigarette pack is installed on the right side of the final oil sealing output device 7 for the entire surface of the cigarette pack. The operating procedure of the device is as follows:

[0071] 1. Unloading of irregularly shaped packaging boxes and BOPP film: The telescopic shaft of the 6.5mm pneumatic lifting and positioning mechanism of the cigarette pack extends and works with the positioning and boxing device to unload the irregularly shaped packaging boxes and BOPP film. After completion, the telescopic shaft of the 6.5mm pneumatic lifting and positioning mechanism of the cigarette pack retracts and lowers the irregularly shaped packaging box wrapped with BOPP film to the initial oil seal position.

[0072] At this point, the irregularly shaped packaging box is placed horizontally, with its bottom wrapped in a BOPP film in the center, as shown. Figure 8 As shown.

[0073] 2. Initial oil sealing on the side of the irregularly shaped packaging box: The telescopic shaft of a set of pneumatic initial oil sealing mechanism 6.3 on the side of the cigarette pack extends, driving the oil sealing hot plate to wrap the BOPP film around the top rear side 010 of the irregularly shaped packaging box for initial oil sealing. After it is in place, the telescopic shaft of a set of pneumatic initial oil sealing mechanism 6.4 on the side of the cigarette pack extends, driving the oil sealing hot plate to wrap the BOPP film around the top front side 011 of the irregularly shaped packaging box for initial oil sealing.

[0074] like Figure 9 As shown, the rear side 010 of the top of the irregularly shaped packaging box refers to the rear portion of the trapezoidal second sidewall 07 at the top center of the sidewall between the right sidewall 08 and the left sidewall 09, and the adjacent triangular first sidewall 06 behind it. The front side 011 of the top of the irregularly shaped packaging box refers to the front portion of the trapezoidal second sidewall 07 at the top center of the sidewall between the right sidewall 08 and the left sidewall 09, and the adjacent triangular first sidewall 06 in front of it.

[0075] 3. Initial oil seal on the right side of the irregularly shaped packaging box (08): A set of dual-axis pneumatic initial oil sealing mechanisms 6.2 first completes the initial oil seal on the upper area (082) of the right side of the cigarette pack. Then, three sets of single-axis pneumatic initial oil sealing mechanisms 6.1 sequentially complete the initial oil seal on the lower area (081), left area (083), and right area (084) of the right side of the irregularly shaped packaging box. Figure 10 As shown;

[0076] Here, the entire right side 08 is divided into four identical triangular regions with the center of the right side 08 as the vertex of the triangle and the "top", "bottom", "left" and "right" sides of the right side 08 as the bases of the four triangles. These regions are respectively denoted as the upper right side region 082, the lower right side region 081, the left right side region 083, and the right right side region 084. Each region is controlled by an independent cylinder.

[0077] 4. Initial oil seal on the left side 09 of the irregularly shaped packaging box: The initial oil seal mechanism 7.1 of the cigarette pack's left side end of the cigarette pack's final oil seal output device 7 performs initial oil seal on the left side 09 of the cigarette pack;

[0078] 5. Uneven packaging box unloading: The telescopic shaft of the pneumatic ejection mechanism 6.6 extends, and the pusher installed on the telescopic shaft pushes the cigarette pack after initial oil sealing to the cigarette pack final oil sealing output device 7 for final oil sealing.

[0079] like Figure 2 As shown, the cigarette pack final oil sealing output device 7 mainly consists of a primary oil sealing mechanism 7.1 on the left end of the cigarette pack, four sets of pneumatic final oil sealing mechanisms 7.2 on the sides of the cigarette pack, a set of pneumatic final oil sealing mechanisms 7.3 on the left end face of the cigarette pack, a set of pneumatic final oil sealing mechanisms 7.4 on the right end face of the cigarette pack, a finished cigarette pack output slot 7.5, a pneumatic cigarette pack ejection slide 7.6, and an X-axis pneumatic slide 7.7. Each oil sealing mechanism is equipped with an oil sealing heat plate, a heating element, and a temperature sensor. Through program control, the device automatically completes the primary oil sealing of the octagonal corners on the left side of the cigarette pack and the final oil sealing of each side, ensuring a firm, flat, and aesthetically pleasing oil seal. After heat sealing, the cigarette packs are ejected by the pneumatic cigarette pack ejection slide 7.6 and arranged one pack at a time.

[0080] Figure 3 This is a schematic diagram of the back structure of the cigarette pack final oil sealing output device 7, showing the structure of the initial oil sealing mechanism 7.1 at the left end of the cigarette pack. The initial oil sealing mechanism 7.1 at the left end of the cigarette pack is located on one side of the four sets of pneumatic final oil sealing mechanisms 7.2 on the sides of the cigarette pack. The space between the four sets of pneumatic final oil sealing mechanisms 7.2 on the sides of the cigarette pack is for accommodating irregularly shaped packaging boxes.

[0081] The primary oil sealing mechanism at the left end of the cigarette pack 7.1 mainly includes: a left octagonal primary oil sealing assembly 7.1.1, a rotary guide assembly 7.1.2, an oil seal opening and closing drive assembly 7.1.3, a drive gear 7.1.4, a drive stepper motor 7.1.5, a reducer 7.1.6, a swing guide assembly 7.1.7, a swing drive cylinder 7.1.8, a mounting base 7.1.9, and a rotary gear disc 7.1.10.

[0082] The stepper motor 7.1.5 and reducer 7.1.6 are connected to the oil seal opening / closing drive assembly 7.1.3 via the drive gear 7.1.4. The oil seal opening / closing drive assembly 7.1.3 includes a drive gear 7.1.3.2. Both the drive gear 7.1.3.2 and the rotating gear 7.1.10 have identical and overlapping circular openings at their centers for inserting the BOPP film (not yet sealed) onto the left side (09) of the irregularly shaped packaging box. Figure 3 The rotating gear disk 7.1.10 has eight left-side octagonal initial oil seal assemblies 7.1.1 arranged circumferentially around its circular opening. Each left-side octagonal initial oil seal assembly 7.1.1 has a triangular hot plate 7.1.1.1.

[0083] like Figure 4 The drive gear 7.1.3.2 has eight slotted openings 7.1.3.1 arranged circumferentially at an angle with a circular opening as the center. Each left-side octagonal initial oil seal assembly 7.1.1 is connected to each of the eight slotted openings 7.1.3.1 via a bearing 7.1.11. Each left-side octagonal initial oil seal assembly 7.1.1 can slide along a radial slide rail 7.1.12. The radial slide rail 7.1.12 is fixed along the radial direction of the rotating gear 7.1.10.

[0084] The specific steps for initial oil sealing on the left side (09) of the irregularly shaped packaging box are as follows:

[0085] 1. Initial state: The initial state of the cigarette pack and BOPP film is as follows... Figure 11 As shown, all eight heating plates (7.1.1.1) are in the open position. Figure 5 As shown.

[0086] 2. The cigarette pack final oil seal output device 7 moves horizontally toward the irregular packaging box, so that the BOPP film portion used to seal the left side 09 of the irregular packaging box passes through the circular opening at the center of the drive gear 7.1.3.2 and the rotating gear 7.1.10.

[0087] 3. The drive gear 7.1.3.2 rotates, causing the slot 7.1.3.1 to rotate as well. The rotating gear 7.1.10 remains stationary. The left octagonal initial oil seal assembly 7.1.1, constrained by the slot 7.1.3.1, moves inward along the radial slide rail 7.1.12, achieving synchronous closing of the eight heating plates 7.1.1.1. The heating plates 7.1.1.1 then cause the BOPP film to adhere to the left side 09 of the cigarette pack, achieving a uniform vertical initial oil seal on the left side 09 of the cigarette pack. Figure 6 As shown.

[0088] 4. After the initial vertical oil seal is completed, drive the toothed disc 7.1.3.2 to rotate in the opposite direction, driving the eight heating plates 7.1.1.1 to open slightly from the closed state (the opening distance can be set by the program), ensuring that the octagonal film will not tear when rotated and flattened. Then, the rotating toothed disc 7.1.10 rotates, driving the eight heating plates 7.1.1.1 to rotate, rotating and flattening the octagonal BOPP film that has completed the initial vertical seal in the same direction, thus achieving the initial oil seal of the octagonal film on the left side 09 of the irregularly shaped packaging box.

[0089] The drive mechanism for the geared disc 7.1.3.2 is conventional, such as through a drive gear 7.1.4 or a stepper motor 7.1.5. The drive mechanism for the rotary geared disc 7.1.10 is also conventional, such as through a oscillating drive motor 7.1.8 or a reducer 7.1.6. The rotary guide assembly 7.1.2 is fixed to the frame, providing support and guidance for the rotary geared disc 7.1.10. The oscillating guide assembly 7.1.7 is fixed to the frame, providing support and guidance for the rotary geared disc 7.1.10. The heating plate 7.1.1.1 is triangular, and it is identical to the eight triangles formed on the left side of the cigarette pack, with the center of the left side 09 as the apex of the triangle and any side of the octagon of the left side 09 as the base. Since the left side of the cigarette pack is octagonal, heating plates 7.1.1.1 in eight directions are needed. First, the BOPP film is folded into eight corners by the linear movement of the heating plate 7.1.1.1, and then the BOPP film is flattened by the rotational movement of the heating plate 7.1.1.1.

[0090] The final oil seal output device 7 for the entire cigarette pack is located to the left of the initial oil seal device 6 for the entire cigarette pack. The operating procedure of the device is as follows:

[0091] 1) When the left end of the cigarette pack is initially sealed with oil, the telescopic shaft of the X-axis pneumatic slide 7.7 extends and pushes the left end initial oil sealing mechanism 7.1 of the cigarette pack to the left end face of the cigarette pack in the full-face initial oil sealing device 6. Under the program control, the left end initial oil sealing mechanism 7.1 first completes the vertical initial oil sealing of the octagon on the left side 09. Then, the eight hot plates 7.1.1.1 in the left octagon initial oil sealing assembly 7.1.1 retract slightly and then rotate and flatten the vertical octagon to complete the initial oil sealing of the left end.

[0092] 2) When the four sides of the cigarette pack are finally sealed with oil, the telescopic shaft of the pneumatic ejection mechanism 6.6 of the cigarette pack initial oil sealing device extends, and the pusher installed on the telescopic shaft pushes the initially sealed cigarette pack to the cigarette pack final oil sealing output device 7. The four sets of pneumatic final oil sealing mechanisms 7.2 on the sides of the cigarette pack act in sequence to complete the final oil sealing of the four sides of the cigarette pack.

[0093] The four sides of the irregularly shaped packaging box refer to the four trapezoidal second sidewalls 07 and / or one of their adjacent triangular first sidewalls 06 between the right sidewall 08 and the left sidewall 09.

[0094] 3) When the two ends of the irregularly shaped packaging box are finally sealed with oil, the pneumatic push-out slide 7.6 pushes the irregularly shaped packaging box between the left pneumatic final oil sealing mechanism 7.3 and the right pneumatic final oil sealing mechanism 7.4 of the cigarette pack end face to perform the final oil sealing of the two ends of the irregularly shaped packaging box (i.e., the right side 08 and the left side 09). After completion, the cigarette pack will stay here and be squeezed out by the subsequent irregularly shaped packaging boxes, so as to realize the sequential output of irregularly shaped packaging boxes.

[0095] The heating element and temperature sensor in this application are used to control the temperature of the oil-sealing heating plate. The shape of the oil-sealing heating plate can be designed according to the surface to be sealed, for example, it can be a square, regular octagon, trapezoidal plate, or a combination of trapezoidal and triangular plates. The positional relationship of each oil-sealing mechanism can be conventionally designed according to its function.
