Description

Technical Field

[0001] This invention relates to the field of cigarette packaging equipment technology, specifically to a double cigarette packaging mechanism. Background Technology

[0002] The most common cigarette packaging on the market is an outer pack containing an inner pack. With this packaging method, once the pack is opened, the unused cigarettes will lose their aroma and become damp, resulting in a poor smoking experience for customers.

[0003] In existing technology, cigarette factories use a double-packet forming channel in the cigarette pack forming process, which can output two cigarette packs at a time. Therefore, considering the shortcomings of existing technology and existing production equipment, there is a need for a packaging mechanism that can package two independent cigarette packs at once. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a double-packaging mechanism for packaging two independent cigarette packs together, thereby reducing the proportion of cigarettes that have lost their aroma and become damp after opening the box, while also meeting the diverse needs of cigarette packs.

[0005] This invention proposes a double cigarette pack packaging mechanism, including a support that can be driven to rotate; a folding station disposed on the outer contour surface of the support; a folding ring disposed along the outer contour surface of the support; two cigarette packs arranged side by side, with a flat outer packaging paper corresponding to one end face of the two cigarette packs; the two cigarette packs together with the outer packaging paper are pushed into the folding station; the rotation of the support causes the outer packaging paper in the folding station to rotate; the outer packaging paper contacts the folding ring; during the movement, the outer packaging paper is folded and wrapped around the outside of the two cigarette packs under the action of the folding ring and the folding station.

[0006] A preferred technical solution of the present invention is as follows: the bracket rotates to drive the folding station to pass through the initial position, the intermediate position and the end position in sequence, and the folding ring is disposed between the initial position and the intermediate position.

[0007] A preferred technical solution of the present invention is as follows: the folding station includes a positioning bottom surface disposed on the outer contour surface of the bracket, and positioning side surfaces disposed perpendicularly on both sides of the positioning bottom surface, so that the folding station has two opposite open ends.

[0008] A preferred technical solution of the present invention is as follows: the folding ring includes a guide ring, which gradually approaches the folding station from the initial position to the intermediate position along the rotation axis of the bracket.

[0009] A preferred technical solution of the present invention is as follows: a rotatable right-angle push plate is provided at the middle position, the right-angle push plate is provided on the end face near the support, and the rotation direction of the right-angle push plate is the same as the folding direction of the outer packaging paper.

[0010] A preferred technical solution of the present invention is as follows: a pressure plate is further provided at the middle position, and the pressure plate can be driven to move towards the middle of the folding station.

[0011] A preferred technical solution of the present invention further includes a limiting mechanism, which includes two opposing limiting end plates. The folding station moves between the two limiting end plates. The limiting end plates are opposite to the opening end of the folding station. The limiting mechanism is located between the initial position and the end position.

[0012] A preferred technical solution of the present invention further includes a limiting top plate mounted between the two limiting end plates, wherein the folding station moves from below the limiting top plate, and the limiting top plate is positioned between the intermediate position and the end position.

[0013] A preferred technical solution of the present invention is as follows: two oppositely arranged guide folding plates are provided on the outer side of the bracket. The guide folding plates are located at the end position. The distance between the two guide folding plates is the same as the distance between the two positioning sides. The double cigarette packs are pushed into the space between the two guide folding plates by the folding station.

[0014] A preferred technical solution of the present invention is that the outer contour surface of the bracket is a circumferential surface, and a plurality of folding stations are evenly spaced on the outer contour surface of the bracket.

[0015] The double-pack cigarette packaging mechanism of the present invention has the following beneficial effects: a folding station is set on a rotating support, and a folding ring is used for guidance, so that the outer packaging paper is folded sequentially during the rotation of the support, so that the outer packaging paper wraps around the outside of the double cigarette packs. The structure of the present invention is compact and can effectively package two independent cigarette packs together, reducing the proportion of cigarettes that have lost their aroma and become damp after opening the box; at the same time, by packaging two flavored cigarette packs together, the diverse needs of cigarettes in the cigarette box packaging can be met.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0026] Please see Figures 2 to 4A double cigarette pack packaging mechanism for packaging two independent cigarette packs together includes a support 11, a folding station 12, and a folding ring 13. The folding station 12 is located on the outer contour surface of the support 11. The support 11 can be driven to rotate. The double cigarette packs 30, together with the outer packaging paper 20, are pushed into the folding station 12. When the support 11 is driven to rotate, it causes the outer packaging paper 20 in the folding station 12 to move. The outer packaging paper 20 contacts the folding ring 13. Under the guidance of the folding ring 13, the outer packaging paper 20 is gradually folded to cover the outside of the double cigarette packs 30, thus completing the packaging of the double cigarette packs 30.

[0027] Figure 1 This is an unfolded view of the outer packaging paper 20 in this embodiment. The dotted lines are fold lines; folding along the dotted lines yields a three-dimensional cigarette box. The outer packaging paper 20 includes a back panel 22, a front panel 21, outer flaps 211, inner flaps, and a bottom flap 231. The outer flaps 211 are located on both sides of the front panel 21, and the inner flaps 221 are located on both sides of the back panel 22. The bottom flap 231 is connected to the inner flaps 221. In the three-dimensional cigarette box formed after folding the outer packaging paper 20, the back panel 22 and the front panel 21 are opposite each other, representing the back and front of the cigarette box, respectively. The two inner flaps 221 are opposite each other, and the two outer flaps 211 are opposite each other, with the outer flaps 211 covering the outside of the inner flaps 221. The bottom flap 231 is located at the bottom of the cigarette box.

[0028] Please see Figures 2 to 6 In this embodiment, to facilitate processing and positioning of the various components, the bracket 11 is formed by two identical rings spaced apart, and its overall shape is circular. Its outer contour surface is two spaced circumferential surfaces, and the folding station 12 is located on the outer contour surface of the bracket 11. The bracket 11 is externally driven by a motor to rotate around its central axis. The two rings are spaced apart to facilitate the ejection of the double cigarette pack 30 from between the two rings in subsequent processes.

[0029] Please see Figure 7 The folding station 12 can be driven sequentially through an initial position a, an intermediate position b, and an end position c. At the initial position a, the double cigarette packs 30, along with the outer packaging paper 20, are pushed into the folding station 12. During the rotation from the initial position a to the end position c, the outer packaging paper 20 is folded and pushed out at the end position c, completing the packaging of the double cigarette packs 30. In this embodiment, the initial position a is located below the support 11, the intermediate position b is opposite to the initial position a and located above the support 11, and the end position c is located to the left of the intermediate position b, spaced 90 degrees apart from the intermediate position b.

[0030] The folding station 12 includes a positioning bottom surface 121 disposed on the outer contour surface of the bracket 11, and positioning side surfaces 122 disposed on both sides of the positioning bottom surface 121. Both the positioning bottom surface 121 and the positioning side surfaces 122 are flat surfaces, so that when the double cigarette packs 30 and the outer packaging paper 20 are pushed into the folding station 12, the outer packaging paper 20 remains flat by contacting the positioning bottom surface 121 and the positioning side surfaces 122. The positioning side surfaces 122 surround the positioning bottom surface 121 so that the folding station 12 forms openings at both ends, and the direction of the line connecting the two openings is in the same direction as the axis of the bracket 11, such as... Figure 5 , Figure 6 As shown.

[0031] Preferably, multiple folding stations 12 are evenly spaced on the outer contour surface of the support 11 to speed up the packaging efficiency of the mechanism. The support 11 can complete the packaging of multiple double cigarette packs 30 in one rotation.

[0032] In the initial position a, both the double cigarette pack 30 and the outer packaging paper 20 are located below the support 11, with the outer packaging paper 20 positioned between the double cigarette pack 30 and the support 11. The back side 22 of the outer packaging paper 20 corresponds to the positioning bottom surface 121 of the folding station 12, and the back side of the double cigarette pack 30 faces upwards. When the double cigarette pack 30 is pushed into the folding station 12, the back side 22 simultaneously contacts the positioning bottom surface 121 and the back side of the double cigarette pack 30. Due to the stop provided by the positioning bottom surface 121, during the pushing process, the inner folding wings 221 located on both sides of the back side 22 are pushed by the positioning side 122 and folded along the dotted line, wrapping around both sides of the double cigarette pack 30. When the double cigarette pack 30 is fully pushed into the folding station 12, the outer packaging paper 20 completes the folding of the back side 22 and the inner folding wings 221, and the front side 21 is in a flat state, extending from the opening end of the folding station 12.

[0033] It should be noted that although the supporting structures of the double cigarette packs 30 and the outer packaging paper 20 are not shown in the accompanying drawings, the conveying and positioning of the double cigarette packs and the outer packaging paper 20 are readily conceived by those skilled in the art. For example, in this embodiment, the double cigarette packs 30 are conveyed side by side from the previous stage to below the initial position a, and the outer packaging paper 20 is held between the double cigarette packs 30 and the support 11 by a finger cylinder. The double cigarette packs 30 are pushed into the folding station 12 by the cylinder.

[0034] A swing mechanism (not shown in the figure) is provided at the initial position a. The swing mechanism performs linear reciprocating motion to fold the bottom flap 231 of the box, which is still in the unfolded state after the inner flap 221 is folded. In this embodiment, the swing mechanism is located below the support 11 and includes a toggle plate and a drive mechanism connected to the toggle plate. The drive mechanism is used to drive the toggle plate to move reciprocally in the horizontal direction, and the distance of unidirectional movement of the toggle plate is greater than the width of the double cigarette pack 30. The toggle plate is a flat thin plate, vertically set at the initial position a, with its two end faces parallel to the positioning side 122. The drive mechanism is a telescopic cylinder. The toggle plate is spaced apart from the end face of the support 11 so that the movement of the toggle plate only folds the bottom flap 231 of the box, without friction or interference with the end face of the support 11.

[0035] The specific working process is as follows: at the initial position a, the actuating plate is located next to the folding station 12. After the double cigarette pack 30 is pushed into the folding station 12, the actuating plate moves to the other side of the folding station 12, pushing the bottom folding wing 231 on one side of the box to fold into the box until it moves to the other side of the folding station 12, and then moves in the opposite direction to fold the bottom folding wing 231 on the other side. The actuating plate repeatedly moves back and forth to fold the bottom folding wing 231 of the box, so that the bottom folding wing 231 of the box is folded loosely along the dotted line, and the folded bottom folding wing 231 of the box is not easy to rebound.

[0036] It should be noted that during the unidirectional movement of the toggle plate, when one of the bottom flaps 231 is pushed to fold inward into the box, the other bottom flap 231 will be folded outward. However, since the dotted line is on the inner end face of the outer packaging paper 20 (i.e. the inner surface of the folded cigarette box), after the bottom flap 231 is toggled and folded along the dotted line, the bottom flap 231 will still tend to fold inward, and the bottom flap 231 will not fold outward.

[0037] The folding ring 13 is located on the outside of the bracket 11, between the initial position a and the intermediate position b. It includes a guide ring 131 and a limiting ring 132. From the initial position a to the intermediate position b, along the central axis of the bracket 11, the guide ring 131 gradually approaches the folding station 12 to guide the front of the box 21, so that the front of the box 21 gradually folds over and covers the double cigarette pack 30.

[0038] Specifically, in this embodiment, the guide ring 131 is cylindrical and bends from the initial position a to the middle position b. The end of the guide ring 131 near the initial position a is the head end, and the end of the guide ring 131 near the middle position b is the tail end. The guide ring 131 and the flat front surface 21 of the box are located on the same side of the support 11. The head end of the guide ring 131 is spaced apart from the end face of the support 11 on that side. The tail end of the guide ring 131 is also spaced apart from the end face of the support 11 on that side, and the distance between the tail end of the guide ring 131 and the end face of the support 11 is less than the distance between the head end of the guide ring 131 and the end face of the support 11. When the folding station 12 moves the outer packaging paper 20 and the double cigarette pack 30 from the initial position a to the middle position b, the flat front surface 21 of the box contacts the guide ring 131 and gradually folds along the dotted line under the guidance and push of the guide ring 131, approaching the folding station 12.

[0039] Preferably, the limiting ring 132 is disposed outside the guide ring 131, and is located away from the support 11 in the radial direction relative to the guide ring 131. In this embodiment, the limiting ring 132 is also a bent round tube. During the movement of the folding station 12, the front of the box 21 passes between the limiting ring 132 and the guide ring 131. The guide ring 131 is used to guide the front of the box 21. The limiting ring 132 is located outside the guide ring 131 to avoid the front of the box 21 being folded too much before it has moved to the middle position b, which would cause the front of the box 21 to interfere with the support 11 and cause wrinkles on the front of the box 21, affecting the packaging quality of the outer packaging paper 20.

[0040] A limiting mechanism 14 is also provided outside the support 11. The limiting mechanism 14 is located between the initial position a and the end position c, and includes two limiting end plates 141 arranged opposite each other at both ends of the support 11. When the support 11 rotates, the folding station 12 moves through the space between the two limiting end plates 141. The two limiting end plates 141 can form stops at the two open ends of the folding station 12 to prevent the cigarette pack from falling off the folding station 12 during movement; at the same time, during the rotation from the initial position a to the middle position b, the bottom flap 231 of the box after being folded at the initial position a can be limited by the limiting end plates 141 to prevent it from springing back and to maintain an inward folded posture, so that the subsequent folding of the front 21 of the box can wrap the bottom flap 231 inside.

[0041] Preferably, to ensure that the front of the box 21 is folded in place and covers the double cigarette pack 30, a right-angle push plate 15 is also provided at the middle position b. The right-angle push plate 15 can be driven to rotate, further folding the front of the box 21, which has been initially folded by the guide ring 131, and deepening the crease of the front of the box 21.

[0042] Specifically, in this embodiment, the right-angle push plate 15 and the flat front surface 21 of the box are located on the same side of the support 11. The end face of the right-angle push plate 15 that contacts the front surface 21 of the box is two perpendicular surfaces. The right-angle push plate 15 is externally connected to a driving device via a connecting rod 151 and is driven to rotate by the driving device. Its rotation direction is the same as the folding direction of the front surface 21 of the box. When the folding station 12 moves to the middle position b, the right-angle push plate 15 rotates, pressing the already folded front surface 21 of the box against the double cigarette pack 30, so that the front surface 21 of the box is further folded.

[0043] Preferably, the limiting mechanism 14 is disconnected at the middle position b to avoid the right-angle push plate 15 and facilitate the rotation of the right-angle push plate 15.

[0044] Preferably, in order to keep the front side 21 of the box after being folded by the right-angle push plate 15 in close contact with the double cigarette pack 30, so as to facilitate the subsequent folding of the outer wing 211, a pressure plate 16 is also provided at the middle position b. The pressure plate 16 can be driven to move towards the middle of the folding station 12 to push the front side 21 of the box closer to the double cigarette pack 30 and keep it in close contact with the double cigarette pack 30.

[0045] Specifically, in this embodiment, the pressure plate 16 is positioned above the bracket 11, directly above the middle position b. The pressure plate 16 is a flat plate, and a rotating shaft 162 is externally connected to the curved arm 161. When the rotating shaft 162 rotates, the curved arm 161 rotates, causing the pressure plate 16 to press down, pressing the front of the box 21 against the double cigarette pack 30 and keeping the front of the box 21 and the double cigarette pack 30 in contact.

[0046] Preferably, to prevent the front surface 21 of the box from rebounding and resetting during movement and separating from the double cigarette pack 30, a limiting top plate 142 is also provided on the limiting mechanism 14 between the middle position b and the end position c. The limiting top plate 142 is located between the two limiting end plates 141. When the bracket 11 rotates, the folding station 12 moves past the limiting end plate 141. The limiting top plate 142 can form a limit above the folding station 12, preventing the folded front surface 21 of the box from separating from the end face of the double cigarette pack 30 after the folding station 12 leaves the middle position b.

[0047] At the end position c, a guide folding plate 18 is provided on the outside of the bracket 11. The two guide folding plates 18 are arranged at intervals, and the distance between the two guide folding plates 18 is the same as the distance between the two positioning sides 122. When the folding station 12 moves to the end position c, one of the positioning sides 122 on the folding station 12 is coplanar with the end face of one of the guide folding plates 18, and the other positioning side 122 on the folding station 12 is coplanar with the end face of the other guide folding plate 18. The double cigarette pack 30 is pushed away from the folding station 12 and enters between the two guide folding plates 18. Under the stopping and limiting action of the guide folding plate 18, the outer folding wings 211 located on both sides of the front of the box 21 are pushed and folded along the dotted line to wrap around the double cigarette pack 30. Thus, the packaging of the double cigarette pack 30 by the outer packaging paper 20 is completed.

[0048] For detailed packaging procedures, please refer to [link / reference]. Figure 7 : The double cigarette pack 30 and the outer packaging paper 20 are placed below the initial position a from bottom to top. The double cigarette pack 30 and the outer packaging paper are pushed into the folding station 12 at the same time after being lifted. During the pushing process, under the restriction of the folding station 12, the back of the box 22 and the inner folding wing 221 are pushed and folded along the dotted line, thus completing the folding of the back of the box 22 and the inner folding wing 221. Next, the swing mechanism reciprocates to fold the bottom flap 231 of the box, and the bracket 11 rotates to complete the folding of the bottom flap 231 of the box. During the movement from the initial position a to the middle position b, under the guidance of the folding ring 13, the flat front of the box 21 gradually folds towards the front of the double cigarette pack 30. The fold is further deepened by the flipping right-angle push plate 15, and the pressure plate 16 pushes the front of the box 21 to fit with the double cigarette pack 30, and the bottom folding wing 231 covers the bottom of the double cigarette pack. During the movement from the middle position b to the end position c, the limiting top plate 142 prevents the front of the box 21 from separating from the double cigarette pack 30, thus completing the folding of the front of the box 21. When the device moves to the end position c, it pushes the double cigarette pack 30 away from the folding station 12 and into the space between the two guide folding plates 18. Under the constraint of the two guide folding plates 18, the outer folding wing 211 is folded, thus completing the outer packaging of the double cigarette pack 30.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
