Description

Technical Field

[0001] The utility model relates to the technical field of tobacco packaging production, and particularly relates to a cigarette packet turning and conveying mechanism. Background Art

[0002] The packaging of cigarette sticks is divided into multiple steps. After the cigarette packet machine packs the cigarette sticks into small boxes, generally, the small boxes need to be transferred to a transparent paper packaging machine for transparent paper wrapping, and the cigarette packet machine and the transparent paper packaging machine are docked through a conveyor belt. For the cigarette packet machine and the transparent paper packaging machine, the length direction during the cigarette packet conveying process needs to be perpendicular to the conveyor belt. However, due to the limitations of the site and equipment structure, in some cases, the output conveyor belt of the cigarette packet machine and the input conveyor belt of the transparent paper packaging machine cannot be directly and linearly docked, and can only be butt-jointed at a right angle at the head and tail. In this case, if the cigarette packets on the output conveyor belt are directly transferred to the input conveyor belt, the problem of incorrect orientation will occur, affecting subsequent packaging. Some existing technologies have set up turning devices at the junction of the output conveyor belt and the input conveyor belt to keep the cigarette packets in the correct orientation. However, these turning devices generally rely on driving mechanisms such as cylinders, with complex structures, large operating noises, and problems of troublesome later maintenance.

[0003] The patent document with the application number CN202020500140.6 discloses a turning mechanism compatible with standard cigarettes and slim cigarettes, which includes a first conveyor belt, a second conveyor belt, a third conveyor belt, and a fourth conveyor belt. The second conveyor belt, the third conveyor belt, and the fourth conveyor belt are connected in sequence. The lateral distance between the first conveyor belt and the second conveyor belt is less than the lateral distance between the first conveyor belt and the fourth conveyor belt. The first conveyor belt and the third conveyor belt are respectively driven by different driving mechanisms. This technical solution uses the speed difference and angular arrangement between the first conveyor belt and the third conveyor belt to enable the cigarette cartons to automatically turn during transportation. However, its function is to convert the cigarette cartons from parallel to the conveyor belt to perpendicular to the conveyor belt, and it cannot be applied to the connection between the cigarette packet machine and the transparent paper packaging machine. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a cigarette packet turning and conveying mechanism, which can convert the cigarette packets from perpendicular to the conveyor belt to parallel to the conveyor belt, making it more convenient for subsequent processing when the cigarette packets are transferred between two conveying platforms with a right-angle connection.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model. Embodiment

[0024] Referring to Figure 1 , the present utility model provides a cigarette pack steering and conveying mechanism, which includes a first transfer unit 1 and a second transfer unit 2. The conveying directions of the first transfer unit and the second transfer unit are perpendicular to each other, and the first transfer unit and the second transfer unit are connected to each other so that the cigarette pack 3 on the first transfer unit can be transferred to the second transfer unit after reaching the end of the first transfer unit; more specifically, the first transfer unit includes a first platform 11 and a second platform 12 that extend linearly and are parallel to each other. The first platform is formed by a first conveyor belt 111, and the second platform is formed by a second conveyor belt 121, a third conveyor belt 122, and a fourth conveyor belt 123 that are connected in sequence. Referring to Figure 2, the second conveyor belt, the third conveyor belt and the fourth conveyor belt are respectively controlled by the first driving roller set 124, the second driving roller set 125 and the third driving roller set 126. The driving directions of the first driving roller set 124 and the third driving roller set 126 are the same as the conveying speed, so that the cigarette packs on the second conveyor belt and the fourth conveyor belt move towards the direction close to the second transfer unit. The second driving roller set 125 has an opposite driving direction. Correspondingly, the driving direction and the driving speed of the power mechanism for driving the first conveyor belt are consistent with those of the first driving roller set and the third driving roller set. The second transfer unit includes a third platform 21, and both the first platform and the second platform are vertically connected to the side of the third platform.

[0025] The working principle of the present utility model is as follows: Refer to Figure 1 , the starting state of the cigarette pack being transferred on the first transfer unit is that both ends are respectively lapped on the first platform and the second platform, and the length direction of the cigarette pack is perpendicular to the extending direction of the first transfer unit. When the cigarette pack reaches the third conveyor belt, the first end of the cigarette pack moves towards the direction close to the second transfer unit under the action of the first conveyor belt, and the second end of the cigarette pack moves towards the direction away from the second transfer unit under the action of the third conveyor belt. These two moving trends cause the cigarette pack to rotate counterclockwise around a certain part in the middle of itself. When the counterclockwise rotation angle is 90°, the length direction of the cigarette pack becomes parallel to the extending direction of the first transfer unit. Then, the cigarette pack is transferred to the second transfer unit through the first conveyor belt and the fourth conveyor belt, so that the length direction of the cigarette pack can be perpendicular to the extending direction of the second transfer unit, which is applicable to the small packet machine and the transparent paper packaging machine with right-angle connection of conveyor belts. Similarly, it is also applicable to some other transfer mechanisms with right-angle connection of conveyor belts and the need to convert the orientation of the conveyed items.

[0026] It should be noted that when the actions of the first conveyor belt and the third conveyor belt on the cigarette pack are equivalent, that is, the frictional forces between the first conveyor belt and the third conveyor belt and the cigarette pack are equal, and the running speeds of the first conveyor belt and the third conveyor belt are the same, the cigarette pack will be in a state of rotating in place and cannot be normally conveyed. Usually, the running speed of the first conveyor belt should be greater than that of the third conveyor belt to ensure that the cigarette pack moves towards the second transfer unit while rotating. It should also be noted that the set length of the third conveyor belt has certain limitations. When the length is set relatively small, the rotation angle is insufficient. When the length is set relatively large, the rotation angle may exceed 90°, which will affect the subsequent transfer to a certain extent.

[0027] In the actual application process of the present utility model, the situation where the rotation angle of the cigarette pack is less than 90° may occur. This is because after the cigarette pack rotates to a certain angle, the torsional forces received at both ends of the cigarette pack are balanced with the frictional resistance that needs to be overcome when the cigarette pack rotates. At this time, the cigarette pack no longer rotates. At this time, a guiding structure can be set to assist in adjusting the angle of the cigarette pack. Figure 3 shows another embodiment of the present utility model. InFigure 3 Among them, the first transfer unit further includes a first guide plate 13 disposed between the first platform and the second platform and a limit side plate 14 disposed outside the first platform. An interval area is formed between the first platform and the second platform. The first guide plate includes a first plate body 131 located in the interval area and a second plate body 132 obliquely extending above the fourth conveyor belt of the first platform. In the conveying direction of the first conveyor belt, the second plate body gradually approaches the first conveyor belt. The cigarette packs that have not been rotated to 90° will be guided after contacting the second plate body and finally enter the channel between the first plate body and the limit side plate. At this time, under the action of the first plate body and the limit side plate, the cigarette packs will be adjusted to a state close to rotating 90° for subsequent transfer and processing. In this technical solution, the cigarette packs in the first transfer unit will finally be completely transferred to the first platform. Therefore, in order to facilitate the accommodation of cigarette packs, the width of the first platform can be set to be greater than that of the second platform. In addition, Figure 3 Another setting method of the guiding structure is also shown, that is, the guiding structure is arranged in the second transfer unit 2. The guiding structure includes two second guide plates 22 located on both sides of the third platform. The second guide plate includes an inclined guide plate 221 whose extending direction gradually approaches the third platform and a straight guide plate 222 parallel to the third platform connected to the extending end of the inclined guide plate. The above-mentioned first guide plate and second guide plate can be set separately or simultaneously.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
