Description

Technical Field

[0001] The invention belongs to the technical field of packaging, and in particular relates to a trademark paper packaging blank for forming a hard cigarette box, and a packaging system and method. Background Art

[0002] The mainstream packaging form of hard-box cigarettes is flip-top hard-box packaging. The flip-top hard-box packaging process generally involves packaging with aluminum foil after the cigarettes are grouped, and forming an inner package wrapped with aluminum foil, wherein the inner package wrapped with aluminum foil is referred to as an aluminum foil cigarette package, and then adding inner frame paper to the aluminum foil cigarette package, and finally packaging with trademark paper and outputting it to the downstream machine, wherein after the inner frame paper is folded and positioned by the inner frame paper folding and positioning mechanism, the aluminum foil cigarette package with the inner frame paper also needs to be transported to the trademark paper folding mechanism for folding and packaging with the trademark paper, so in addition to the need to set up the inner frame paper folding and positioning mechanism, the aluminum foil cigarette package with the inner frame paper also increases the risk of displacement of the inner frame paper during the process of transporting the aluminum foil cigarette package with the inner frame paper to the trademark paper folding mechanism. In addition, the glue area of ​​the current flip-top hard-box trademark paper is relatively small, and it is easy to crack in the subsequent process. At the same time, when consumers have few cigarettes left during use, the cigarette package is easy to collapse and shrink, affecting the consumer experience.

[0003] Chinese patent CN209160252U discloses a blank capable of forming a cigarette packaging box and a cigarette packaging box, wherein the blank capable of forming a cigarette packaging box includes: a box body panel for forming a box body; a box cover panel connected to the box body panel for forming a box cover; and an inner layer folding wing for forming the inner layer of the box cover, and the inner layer folding wing is provided with a notch that matches the hanging ear provided on the inner frame of the cigarette packaging box to prevent the box cover from springing open after closing. The packaging box in the patent is formed by folding the box body panel and the box cover panel connected together, and an independent inner frame paper is also provided in the packaging box, so it is necessary to set up an inner frame paper cutting and conveying mechanism and an inner frame paper folding and positioning mechanism, and the aluminum foil cigarette pack with the inner frame paper also increases the risk of displacement of the inner frame paper during the process of conveying the aluminum foil cigarette pack with the inner frame paper to the trademark paper folding mechanism.

[0004] Chinese patent CN103332321A discloses a packaging device and a packaging method for a cover-type cigarette packaging box. The packaging paper forming the vertical packaging type cigarette packaging box is made of thin cardboard or similar packaging materials, including a box body front wall, a box body bottom wall, a box body rear wall, a cover sheet top wall, a cover sheet front wall, and a cover sheet pull tab which are longitudinally connected in sequence. The top of the box body front wall forms an inverted trapezoidal notch, and the two sides of the box body front wall are respectively connected to the left outer wall of the box body and the right outer wall of the box body. The two sides of the box body rear wall are respectively connected to the left inner wall of the box body and the right inner wall of the box body. The top of the right inner wall of the box body is connected to the right inner corner of the box body, and the top of the left inner wall of the box body is connected to the left inner corner of the box body. The cigarette packaging box formed in this patent belongs to a hardened soft box, that is, the current soft box trademark paper is replaced with a packaging box formed by a hard material. After the packaging box is closed, a gap is left between the left end of the top wall of the cover and the top of the left wall of the box body, and a gap is left between the right end of the top wall of the cover and the top of the right wall of the box body. Therefore, the sealing of the packaging box is poor, and the cover pull tab is adhered to the front wall of the box body. Every time a cigarette in the packaging box is taken out, the cover pull tab must be pulled open. For a long time, the cover pull tab will not be able to stick to the front wall of the box body. Therefore, there may be a situation where the cover pull tab cannot stick to the front wall of the box body before the cigarettes in the packaging box are used up. Moreover, the front wall of the box body is a single-layer structure. When there are not many cigarettes left in the packaging box, the cigarette packs are prone to collapse and shrivel.

[0047] S2, the trademark paper folding disk rotates clockwise intermittently and transmits the stuck trademark paper 1 to the other stations in turn. When the trademark paper 1 is transmitted to the second station, the second station completes the folding of the cover sheet tongue 101, so that the cover sheet tongue 101 is bonded to the cover sheet front wall 102, and the second station folds the left side wall 115 and the right side wall 116 of the inner frame paper upward by 90 degrees, so that the left side wall 115 and the right side wall 116 of the inner frame paper are both perpendicular to the front wall 106 of the inner frame paper, and the second station folds the front wall 106 of the inner frame paper upward by 90 degrees, so that the front wall 106 of the inner frame paper is perpendicular to the bottom wall 105 of the box body, and the left short side wing 117 and the right short side wing 118 of the inner frame paper are both in contact with the bottom wall 105 of the box body, and the trademark paper 1 is folded from the second station During the process of being conveyed from the second station to the third station, the fixed folder between the second station and the third station folds the front wall 102, the left side wall 107 and the right side wall 108 of the cover sheet downward at an angle. When the trademark paper 1 is conveyed to the third station, the aluminum foil cigarette pack 3 is conveyed to the third station, and the third station cooperates with the pushing action of the aluminum foil cigarette pack 3 to pre-fold the bottom wall 105 of the box body at a certain angle upward, and folds the left inner wing 109 and the right inner wing 110 of the cover sheet upward by 90° for the first time. After the aluminum foil cigarette pack 3 is pushed forward, the third station completes the folding of the bottom wall 105 of the box body, making the bottom wall 105 of the box body perpendicular to the rear wall 104 of the box body, and folds the left inner wing 109 and the right inner wing 110 of the cover sheet close to the top wall 103 of the cover sheet. The second folding of the cover sheet 109 and the right inner wing 110 of the cover sheet is performed inwardly by 90 degrees, so that the left inner wing 109 and the right inner wing 110 of the cover sheet are both L-shaped. In the process of the trademark paper 1 being transferred from the third station to the fourth station, the fixed folder between the third station and the fourth station folds the front wall 102, the left side wall 107 and the right side wall 108 of the cover sheet upward and restores them to a horizontal position. When the trademark paper 1 is transferred to the fourth station, the fourth station glues the left side wall 107 and the right side wall 108 of the cover sheet, and glues the left side wall 111, the left front wall 113, the right side wall 112 and the right front wall 114 of the box body. In the process of the trademark paper 1 being transferred from the fourth station to the fifth station, the fixed folder between the fourth station and the fifth station folds the front wall 102, the left side wall 107 and the right side wall 108 of the cover sheet upward and restores them to a horizontal position. The wall 102 and the top wall 103 of the cover sheet are folded so that the top wall 103 of the cover sheet is perpendicular to the rear wall 104 of the box body, and the front wall 102 of the cover sheet is attached to the front wall 106 of the inner frame paper. When the trademark paper 1 is conveyed to the fifth station, the fifth station folds the left side wall 107 and the right side wall 108 of the cover sheet inwardly so that the left side wall 107 of the cover sheet is bonded to the left inner wing 109 of the cover sheet, and the right side wall 108 of the cover sheet is bonded to the right inner wing 110 of the cover sheet. When the trademark paper 1 is conveyed to the sixth station, the sixth station folds the left side wall 111 and the right side wall 112 of the box body upwardly so that the left side wall 111 of the box body is bonded to the left side wall 115 of the inner frame paper, and the right side wall 112 of the box body is bonded to the right side wall 116 of the inner frame paper. When the trademark paper 1 is conveyed to the seventh station,The seventh station folds the left front wall 113 and the right front wall 114 of the box body inwards, so that the left front wall 113 and the right front wall 114 of the box body are bonded to the inner frame paper front wall 106 to form a shaped cigarette package 4;

[0048] S3, the seventh station outputs the formed cigarette pack 4 to the formed cigarette pack conveying mechanism, and the formed cigarette pack conveying mechanism conveys the formed cigarette pack 4 to the downstream machine for packaging of cigarette pack transparent paper and packaging of strip boxes and strip box transparent paper.

[0049] In the present invention, the front wall of the hard cigarette box 2 formed by folding the trademark paper 1 is divided into a left front wall and a right front wall. The left front wall and the right front wall of the hard cigarette box 2 are arranged symmetrically on the left and right, and have the characteristics of Chinese cigarettes. The left front wall and the right front wall of the hard cigarette box 2 form two independent design areas on the front of the cigarette box. In one embodiment, two aluminum foil cigarette packs can be simultaneously conveyed to the third work station, wherein each aluminum foil cigarette pack contains ten cigarettes. The formed cigarette pack thus formed contains two aluminum foil cigarette packs, each of which is filled with cigarettes of the same flavor and specification. The flavors or specifications of the cigarettes filled in the two aluminum foil cigarette packs may be different, forming a double aluminum foil cigarette pack packaging form that is consistent inside and outside.

[0050] In the present invention, since the trademark paper 1 is designed to be bilaterally symmetrical, in another embodiment, the trademark paper 1 can be folded during the linear motion of the trademark paper 1, and the aluminum foil cigarette pack 3 can be wrapped in the folded trademark paper 1 to form a shaped cigarette pack 4.

[0051] In summary, the trademark paper 1 of the present invention combines the functions of the flip-top hard cigarette box trademark paper and the inner frame paper, integrates the inner frame paper on the trademark paper 1, and does not need to be separately set on the aluminum foil cigarette pack 3. Therefore, it is not necessary to fold and position the inner frame paper separately through the inner frame paper folding and positioning mechanism, thereby eliminating the inner frame paper cutting and conveying mechanism and the inner frame paper folding and positioning mechanism, simplifying the packaging process, and significantly reducing the floor space of the tobacco packaging production line. In addition, in the process of conveying the aluminum foil cigarette pack 3 to the trademark paper folding mechanism, since the inner frame paper is not set on the aluminum foil cigarette pack 3, the inner frame paper is not set on the aluminum foil cigarette pack 3. , thereby avoiding the risk of displacement of the inner frame paper of the aluminum foil cigarette pack 3 with the inner frame paper during the transportation to the trademark paper folding mechanism, the inner frame paper front wall 106, the inner frame paper left side wall 115 and the inner frame paper right side wall 116 integrated on the trademark paper 1 are more accurately positioned, and the left front wall, right front wall, left side wall and right side wall of the hard cigarette box 2 are all double-layer structures, so the structure of the hard cigarette box 2 is more solid and not easy to deform. In this way, the possibility of the cigarette pack being squeezed and deflated when a small amount of cigarettes is stored in the hard cigarette box 2 is reduced, the cigarette pack is not easy to collapse and shrunken, and the consumer experience is good.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
