Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco packaging equipment, and in particular relates to a packaging and stacking mechanism for cigarette packages. Background Art

[0002] Currently, in the packaging process of finished cigarette rods, there are two common packaging forms: "25 flat packs" and "10 upright packs". Among them, "25 flat packs" are to divide the cigarette packs into two layers, with five packs of cigarettes placed side by side on each layer.

[0003] In the prior art, when stacking and conveying cigarette packs, when the detection probe detects that the upper layer is fully stacked with five cigarette packs and the lower layer is fully stacked with five cigarette packs, that is, the cigarette rods to be packaged are formed, the brake diaphragms on both sides of the cigarette pack stacking and conveying channel will clamp the cigarette packs until the rod pushing is completed, and then the brake diaphragms are released to continue the next cycle. However, when stacking and conveying cigarette packs in this way, due to the friction resistance between the oil seals on the surfaces of the upper and lower cigarette packs, the lower cigarette packs are prone to misalignment during the stacking process, which makes it easy for the packs to be lost or clamped during the conveying process. Therefore, how to design a packing mechanism so that the cigarette rods to be packaged are not easily lost or clamped during the conveying process has become a technical problem that technicians in this field urgently need to solve.

[0028] In order to enable those skilled in the art to better understand the technical solution of the utility model, the solution will be further described in detail below in conjunction with specific embodiments.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a packing mechanism for stacking cigarette packets, which comprises an upper cigarette packet conveyor belt 31, a lower cigarette packet conveyor belt 21, a cigarette strip conveyor belt 11, a first pack pushing mechanism, and a second pack pushing mechanism 71. The upper cigarette packet conveyor belt 31 is arranged on the left side of the cigarette strip conveyor belt 11, and the lower cigarette packet conveyor belt 21 is arranged on the right side of the cigarette packet conveyor belt 11; a plurality of stoppers 12 are evenly arranged on the top surface of the cigarette strip conveyor belt 11, and the spacing between two adjacent stoppers 12 is equal to the sum of the widths of five cigarette packets placed side by side; the top surface of the lower cigarette packet conveyor belt is flush with the top surface of the cigarette strip conveyor belt, and a plurality of cigarette packets 13 are placed side by side on the top surface of the lower cigarette packet conveyor belt; the top surface of the upper cigarette packet conveyor belt and the top surface of the lower cigarette packet conveyor belt The top surfaces of the placed cigarette packs are flush with each other, and multiple cigarette packs are placed side by side on the top surface of the upper cigarette pack conveyor belt; the first pack pushing mechanism is arranged on the right side of the lower cigarette pack conveyor belt, and the second pack pushing mechanism 71 is arranged on the left side of the upper cigarette pack conveyor belt; the first pack pushing mechanism is used to push the five cigarette packs placed side by side on the lower cigarette pack conveyor belt into the lower part of the two adjacent blocks together, and the second pack pushing mechanism is used to push the five cigarette packs placed side by side on the upper cigarette pack conveyor belt into the upper part of the two adjacent blocks together; after the first pack pushing mechanism completes the pack pushing action, it continues to block the five cigarette packs pushed by it until the second pack pushing mechanism completes the pack pushing action, and then the first pack pushing mechanism and the second pack pushing mechanism simultaneously move away from the cigarette strip conveyor belt.

[0030] The embodiment of the utility model provides a packing mechanism for stacking cigarette packs, wherein the top surface of the lower cigarette pack conveyor belt 21 is flush with the top surface of the cigarette rod conveyor belt, and the top surface of the upper cigarette pack conveyor belt 31 is flush with the top surface of the cigarette pack 13 placed on the top surface of the lower cigarette pack conveyor belt, so that the vertical height difference between the upper cigarette pack conveyor belt 31 and the lower cigarette pack conveyor belt 21 is equal to the thickness of one cigarette pack 13. When in use, the first pack pushing mechanism is first used to push the five cigarette packs placed side by side on the lower cigarette pack conveyor belt into the lower parts of two adjacent blocks 12 as the lower cigarette packs, and then the second pack pushing mechanism is used to push the five cigarette packs placed side by side on the upper cigarette pack conveyor belt into the upper parts of the two adjacent blocks as the upper cigarette packs, thereby achieving the stacking of the upper cigarette packs on the lower cigarette packs to form the cigarette rods 14 to be packaged in the form of "two-five flat packs". At the same time, after the first package pushing mechanism pushes the five cigarette packages lying side by side on the lower cigarette package conveyor belt into the lower parts of the two adjacent blocks, it continues to block the five cigarette packages pushed by it without returning to its position until the second package pushing mechanism pushes the five cigarette packages lying side by side on the upper cigarette package conveyor belt into the upper parts of the two adjacent blocks, and then the first package pushing mechanism and the second package pushing mechanism simultaneously move away from the cigarette rod conveyor belt and return to their respective positions. In this way, during the package pushing action of the second package pushing mechanism, when the upper cigarette package slides on the lower cigarette package, although there is friction between the two, the first package pushing mechanism blocks the five cigarette packages of the lower cigarette package, making it difficult for the lower cigarette package to be misplaced. At the same time, the two adjacent blocks can be used to limit the position of the cigarette rods to be packaged, thereby better avoiding the phenomenon of package loss and package clamping during stacking and conveying.

[0031] Furthermore, the first package pushing mechanism includes a driving mechanism and a pushing plate, the pushing plate is parallel to the top surface of the lower cigarette pack conveyor belt, the pushing plate includes a connecting plate 41 and a package pushing plate 42, the left end of the connecting plate 41 is vertically connected to the middle position of the right side surface of the package pushing plate 42, and the right end of the connecting plate is connected to the driving mechanism; the left side surface of the package pushing plate 42 is used to contact the right end surfaces of five cigarette packs placed side by side on the lower cigarette pack conveyor belt, the extension direction of the package pushing plate is the same as the extension direction of the lower cigarette pack conveyor belt, and the extension length of the package pushing plate 42 is equal to the sum of the widths of the five cigarette packs placed side by side; the driving mechanism is used to drive the package pushing plate to move horizontally in the left and right directions. With this solution, since the extended length of the pack pushing plate is equal to the sum of the widths of five cigarette packs placed side by side, during the process of pushing the cigarette packs, the left side of the pack pushing plate can contact both the front and rear ends of the right end faces of the lower layer of cigarette packs, i.e., cover the right end faces of the five cigarette packs, thereby relatively smoothly pushing the five cigarette packs between two adjacent blocks on the cigarette conveyor belt, and at the same time better preventing the five cigarette packs from tilting during the pushing process.

[0032] Preferably, the extension length of the stopper 12 in the left-right direction is equal to the length of a cigarette pack. The height of the stopper in the vertical direction can be flexibly set as needed, and its height can be slightly greater than the height of a cigarette pack or 1.5 times the height of a cigarette pack or slightly less than the height of two cigarette packs; the pack pushing plate can be a flat plate placed upright, so as to effectively increase its contact area with the cigarette pack; the length of the pack pushing plate in the vertical direction, i.e., the height, can be equal to or slightly less than the height of a cigarette pack.

[0033] It can be understood that the spacing between two adjacent stoppers 12 is equal to the sum of the widths of five cigarette packs placed side by side, that is, after the upper and lower cigarette packs are stacked, the front end of the cigarette pack located in the frontmost layer contacts the rear side of the block in front of it, and the rear side of the cigarette pack located in the rearmost layer contacts the front side of the block behind it. The two adjacent stoppers are used to limit the upper and lower cigarette packs after stacking, play a role in stabilizing the cigarette packs, so as to facilitate the packaging of the next process, and can also effectively prevent the packs from being lost during the transportation process.

[0034] Specifically, the driving mechanism includes a driving motor 46, a first connecting rod 51, a second connecting rod 52, a third connecting rod 53, a fourth connecting rod 54, a fifth connecting rod 55, a sixth connecting rod 56, and a mounting plate 45. The driving motor is arranged in the middle position of the mounting plate 45. The lower end of the first connecting rod 51 is connected to the output shaft of the driving motor. The upper end of the first connecting rod is rotatably connected to the left end of the second connecting rod through a first rotating shaft 61. The middle position of the second connecting rod is rotatably connected to the right side of the mounting plate through a second rotating shaft 62. The right end of the second connecting rod is connected to the middle position of the third connecting rod through a third rotating shaft 63. The fourth connecting rod is a bent plate bent to the upper right, and the middle position of the fourth connecting rod 54 is connected to the lower right end of the mounting plate 45; the lower end of the third connecting rod is connected to the left end of the fourth connecting rod through the fourth rotating shaft 64, and the upper end of the third connecting rod is rotatably connected to the middle position of the sixth connecting rod 56 through the fifth rotating shaft 65, and the upper end of the fifth connecting rod 55 is rotatably connected to the right end of the sixth connecting rod through the sixth rotating shaft 66, and the lower end of the fifth connecting rod is rotatably connected to the upper right end of the fourth connecting rod 54 through the seventh rotating shaft 67; the right end of the connecting plate is connected to the left end of the sixth connecting rod. By adopting this scheme, the output shaft of the driving motor rotates clockwise or counterclockwise, which will drive the first connecting rod to rotate accordingly, and then each connecting rod rotates around its corresponding rotating shaft, driving the pack pushing plate 42 to move horizontally back and forth in the left and right directions to approach or move away from the cigarette conveyor belt, thereby achieving five adjacent and side-by-side cigarette packs to be pushed into place and the pack pushing plate to return to its original position; at the same time, the fifth connecting rod can ensure that the right end of the sixth connecting rod does not tilt up, and the left end of the sixth connecting rod is prevented from falling, so that the pack pushing plate maintains horizontal movement, thereby improving the accuracy of the pack pushing action and improving the cigarette pack stacking efficiency.

[0035] It can be understood that when five cigarette packs placed side by side are located between two adjacent blocks and the left and right end faces of the cigarette packs are flush with the left and right end faces of the blocks, respectively, the five cigarette packs are considered to be pushed into place; the pack pushing plate returns to its position, that is, the pack pushing plate returns to its initial position, that is, the pack pushing plate is driven by the driving mechanism to move to the right side of the lower cigarette pack conveyor belt without contacting the cigarette packs.

[0036] Preferably, the drive motor 46 is a servo motor.

[0037] Specifically, the upper end of the third connecting rod 53 has an upper U-shaped opening 531, and the lower end thereof has a lower U-shaped opening 532. The upper U-shaped opening 531 extends vertically downward to the middle position of the third connecting rod. The right end of the second connecting rod 52 is located in the lower part of the upper U-shaped opening and is rotationally connected to the two side walls of the lower part of the upper U-shaped opening through a third rotating shaft. The middle position of the sixth connecting rod 56 is located in the upper part of the upper U-shaped opening and is rotationally connected to the two side walls of the upper part of the upper U-shaped opening through a fifth rotating shaft. The left end of the fourth connecting rod 54 is located in the lower U-shaped opening, and the left end of the fourth connecting rod is rotationally connected to the two side walls of the lower U-shaped opening through a fourth rotating shaft, so that when the driving motor rotates, the rotation of each connecting rod is relatively stable, ensuring that the push pack plate can be relatively stable. The specific placement method of the five cigarette packs placed side by side is as follows: Figure 1 shown.

[0038] Preferably, a waist-shaped hole 47 is provided on the third connecting rod to facilitate adjustment of the connection position of the second connecting rod 52 and the third connecting rod 53; a rear side rod 44 can be vertically provided on the right side surface of the rear end of the package pushing plate, so that when in use, the rear side surface of the rear side rod is aligned with the front side surface of the corresponding block, indicating that the two adjacent blocks have reached the specified position, and then the package pushing action can be performed.

[0039] Furthermore, reinforcing plates 43 are provided between the front and rear sides of the connecting plate 41 and the push plate 42, so as to effectively improve the overall strength of the push plate.

[0040] Specifically, Figure 2 As shown, the second package pushing mechanism 71 has the same structure as the first package pushing mechanism.

[0041] It can be understood that the driving motors in the two pack pushing mechanisms can be electrically connected to the controller, and each conveyor belt is provided with an in-position sensor electrically connected to the controller. When in use, when it is detected that two adjacent blocks on the cigarette strip conveyor belt have arrived at the cigarette pack stacking station, it will also be detected that the five cigarette packs placed side by side on the upper cigarette pack conveyor belt, i.e. the upper cigarette packs, and the five cigarette packs placed side by side on the lower cigarette pack conveyor belt, i.e. the lower cigarette packs, have arrived at the cigarette pack stacking station. At this time, the controller controls the driving motor of the first pack pushing mechanism to start running, and drives its pack pushing plate to perform the pack pushing action, which can The lower cigarette pack can be accurately pushed to between the lower parts of two adjacent blocks, thus avoiding interference between the lower cigarette pack and the two blocks during the pushing process. When the lower cigarette pack is pushed into place, the controller controls the driving motor of the second pack pushing mechanism to start running, and drives its pack pushing plate to perform the pack pushing action, so that the upper cigarette pack can be accurately pushed to between the upper parts of the two adjacent blocks and stacked one by one with the lower cigarette pack to become the cigarette rods to be packaged, thus avoiding interference between the upper cigarette pack and the two blocks during the pushing process, thereby realizing automatic and accurate pushing and high-quality stacking of the cigarette packs.

[0042] Specifically, the upper cigarette pack conveyor belt, the lower cigarette pack conveyor belt, the cigarette rod conveyor belt and the mounting plate 45 are respectively connected to the body of the packaging machine. After the upper cigarette packs and the lower cigarette packs are stacked into cigarette rods 14 to be packaged, the cigarette rods to be packaged are conveyed by the cigarette rod conveyor belts.

[0043] The above are only preferred implementation modes of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
