Description

Technical Field

[0001] This invention relates to the field of cigarette processing technology, and more specifically, to a cigarette pack reversing device and a cigarette packaging machine. Background Technology

[0002] Currently, in the tobacco industry, small cigarette packs are packaged into cartons and then transported to the boxing area via a carton conveyor channel, where boxing machines perform processes such as packing and sealing.

[0003] With the development of the tobacco industry and the need for personalized customization, the outer wrapping film of cigarette cartons has gradually incorporated special processes such as colored film and patterned designs. Furthermore, with the advancement of QR codes in the industry, QR code labels have been designed at the top of the cigarette cartons, requiring scanning and association before sealing. Because the direction of the cigarette cartons produced by packaging machines is fixed, and the sealing machine inlet is also fixed, with the beginning and end aligned, the only way to achieve this is through a series of actions such as rotation and reversal via the cigarette carton conveyor line. Currently, most cigarette carton conveyor lines are located high in the air, and conventional technologies, including clamping rotation and cylinder pushers, have proven ineffective in practice. Summary of the Invention

[0004] The present invention aims to provide a tobacco pack reversing device to improve the problem of the complex structure of existing tobacco pack reversing devices.

[0005] According to one aspect of the present invention, a tobacco pack reversing device is provided, the tobacco pack reversing device comprising:

[0006] frame;

[0007] A conveyor belt, the width of which is adapted to the width of the cigarette pack, includes a first conveyor belt and a second conveyor belt arranged side by side along the width direction. The distance between the end of the first conveyor belt and the end of the second conveyor belt in the direction of movement is not less than the length of the cigarette pack, so as to form a cigarette pack drop opening that allows the cigarette pack to fall.

[0008] The slide, including the inlet that connects to the drop opening of the cigarette pack, has a width that matches the length of the cigarette pack.

[0009] In some embodiments, the tobacco pack reversing device further includes two stop components respectively disposed at both ends of the conveyor belt in the width direction. The two stop components are parallel and spaced apart, and the distance between the two stop components is adapted to the width direction of the tobacco pack.

[0010] In some embodiments, the cigarette pack reversing device further includes a blocking structure disposed at the end of the conveyor belt along the direction of movement of the cigarette pack, wherein the end of the second conveyor belt along the direction of movement of the cigarette pack is farther away from the blocking structure than the end of the first conveyor belt along the direction of movement of the cigarette pack, so as to form a cigarette pack drop outlet at the end of the second conveyor belt along the direction of movement of the cigarette pack and the blocking structure.

[0011] In some embodiments, the slide includes:

[0012] The first housing includes a first side plate perpendicular to the moving direction of the tobacco pack and a first bottom plate disposed at the bottom of the first side plate. The first side plate is disposed at the end of the first conveyor belt along the moving direction of the tobacco pack.

[0013] The second housing includes a second side plate perpendicular to the moving direction of the cigarette pack and a second bottom plate located at the bottom of the second side plate. The second side plate is located at the end of the second conveyor belt along the moving direction of the cigarette pack. The distance between the second side plate and the first side plate is adapted to the length of the cigarette pack. The cigarette pack drop outlet is formed between the first side plate and the second side plate.

[0014] In some embodiments, a blocking structure is formed at the end of the first side plate near the conveyor belt, and a notch is provided on the second side plate to allow the cigarette pack to move toward the cigarette pack drop outlet.

[0015] In some embodiments, the chute extends in an arc shape in a plane perpendicular to the direction of movement of the cigarette pack, the conveyor belt extends in a horizontal direction, the top of the chute is tangent to the vertical direction and communicates with the cigarette pack drop opening, and the bottom of the chute is tangent to the horizontal direction and forms an outlet for outputting the cigarette pack.

[0016] In some embodiments, the cigarette pack drop outlet is located at the end of the conveyor belt away from the exit of the chute along the width direction of the conveyor belt.

[0017] In some embodiments, the cigarette pack drop outlet is located at one end of the conveyor belt near the exit of the chute along the width direction of the conveyor belt.

[0018] In some embodiments, the pack reversing device further includes a slide plate located at the beginning of the conveyor belt for conveying packs of tobacco onto the conveyor belt.

[0019] According to another aspect of the present invention, a cigarette packaging machine is also provided, which includes the above-described cigarette pack reversing device.

[0020] By applying the technical solution of this application, the method of transporting cigarette packs is changed simply by shortening the length of one of the conveyor belts, thus improving the problem of the complex structure of the cigarette pack reversing device in the prior art.

[0034] Unless otherwise specified, the term "or" is inclusive in this application. For example, the phrase "A or B" means "A, B, or both A and B". More specifically, the condition "A or B" is satisfied by any of the following conditions: (A is true or exists) and B is false or does not exist; (A is false or does not exist) and B is true or exists; or (A and B are both true or exist).

[0035] Combination Figures 1 to 4 As shown, the tobacco pack reversing device in this embodiment includes a frame 1, a conveyor belt 2, and a slide 4.

[0036] The width of the conveyor belt 2 is adapted to the width of the cigarette pack 3. The conveyor belt 2 includes a first conveyor belt 21 and a second conveyor belt 22 arranged side by side along the width direction. The length of the distance between the end of the first conveyor belt 21 and the end of the second conveyor belt 22 in the moving direction is not less than the length of the cigarette pack 3, so as to form a cigarette pack drop opening 23 that allows the cigarette pack 3 to fall.

[0037] The slide 4 includes an inlet that communicates with the cigarette pack drop opening 23, and the width of the slide 4 is adapted to the length of the cigarette pack 3.

[0038] In this embodiment, as the cigarette pack 3 moves on the conveyor belt 2, the length direction of the cigarette pack 3 is consistent with the length direction of the conveyor belt 2. After entering the conveyor belt 2, the cigarette pack 3 moves towards the end of the conveyor belt 2 under the action of the conveying force provided by the first conveyor belt 21 and the second conveyor belt 22. In the direction of movement of the cigarette pack 3, the distance by which the end of the first conveyor belt 21 protrudes beyond the end of the second conveyor belt 22 is not less than the length of the cigarette pack. Therefore, a cigarette pack drop hole 23 is formed between the end of the second conveyor belt 22 and the end of the first conveyor belt 21. At the position of the cigarette pack drop hole 23, the second conveyor belt 2 is hollowed out, and the cigarette pack 3 is only carried by the first conveyor belt 21. Moreover, the width of the first conveyor belt 21 is insufficient to carry the cigarette pack 3. Therefore, the cigarette pack 3 falls from the cigarette pack drop hole 23 into the inlet of the slide 4.

[0039] The slide 4 extends in a plane perpendicular to the conveyor belt 2, so the cigarette pack reversing device of this embodiment can switch the cigarette pack 3 from one of the two intersecting directions to the other. The change of the cigarette pack 3 is achieved simply by shortening the length of one of the conveyor belts, which improves the problem of the complex structure of the cigarette pack reversing device in the prior art.

[0040] The cigarette pack reversing device also includes two stop components 5 respectively located at both ends of the width direction of the conveyor belt 2. The two stop components 5 are parallel and spaced apart, and the distance between the two stop components 5 is adapted to the width direction of the cigarette pack 3.

[0041] In some embodiments, a flared opening is formed at the beginning of the conveyor belt 3 along the direction of tobacco pack movement to facilitate the entry of the tobacco pack 3 into the space between the two stop members 5.

[0042] The cigarette pack reversing device also includes a blocking structure 41a located at the end of the conveyor belt 2 along the moving direction of the cigarette pack 3. The end of the second conveyor belt 22 along the moving direction of the cigarette pack 3 is farther away from the blocking structure 41a than the end of the first conveyor belt 21 along the moving direction of the cigarette pack 3, so that the cigarette pack drop opening 23 is formed at the end of the second conveyor belt 22 along the moving direction of the cigarette pack 3 and the blocking structure 41a. The blocking structure 41a helps to prevent the cigarette pack 3 from continuing to move forward due to inertia and the action of the first conveyor belt 21 after it is no longer carried by the second conveyor belt 22 (i.e., enters the cigarette pack drop opening 23), thereby more accurately ensuring that the cigarette pack enters the slide 4.

[0043] The slide 4 includes a first housing 41 and a second housing 42. The first housing 41 includes a first side plate perpendicular to the moving direction of the tobacco pack 3 and a first bottom plate disposed at the bottom of the first side plate. The first side plate is disposed at the end of the first conveyor belt 21 along the moving direction of the tobacco pack 3.

[0044] The second housing 42 includes a second side plate perpendicular to the moving direction of the cigarette pack 3 and a second bottom plate located at the bottom of the second side plate. The second side plate is located at the end of the second conveyor belt along the moving direction of the cigarette pack 3. The distance between the second side plate and the first side plate is adapted to the length of the cigarette pack 3. The cigarette pack drop opening 23 is formed between the first side plate and the second side plate.

[0045] The first side plate of the first housing 41 is perpendicular to the extension direction of the conveyor belt 2, the second side plate of the second housing 42 is perpendicular to the extension direction of the conveyor belt 2, the distance between the first side plate and the second side plate moves in the length direction of the cigarette pack 3, the movement direction of the cigarette pack 3 in the slide 4 is consistent with the width direction of the cigarette pack, and the movement direction of the cigarette pack 3 on the conveyor belt 2 is consistent with the length direction of the cigarette pack 3.

[0046] The first side plate has a blocking structure 41a at the end near the conveyor belt 2. The second side plate has a notch that allows the cigarette pack 3 to move toward the cigarette pack drop port 23. As the cigarette pack 3 moves on the conveyor belt 2, it enters the cigarette pack drop port 23 through the notch. After moving to the position of the cigarette pack drop port 23, the cigarette pack 3 is only supported by the first conveyor belt 21, so it can fall into the cigarette pack drop port 23.

[0047] The slide 4 extends in an arc shape in a plane perpendicular to the moving direction of the cigarette pack 3. The conveyor belt 2 extends in a horizontal direction. The top of the slide 4 is tangent to the vertical direction and communicates with the cigarette pack drop outlet 23. The bottom of the slide 4 is tangent to the horizontal direction and forms an outlet for outputting the cigarette pack 3. Thus, the cigarette pack 3 can be switched from being conveyed by the conveyor belt 2 to being conveyed in a direction perpendicular to the conveyor belt.

[0048] In some embodiments, the cigarette pack drop outlet 23 is located at one end of the conveyor belt 2 away from the exit of the chute 4 along the width direction of the conveyor belt 2, see [reference]. Figure 1 and3 Because the cigarette pack drop outlet 23 is located at the end far from the exit of the slide 4, the first side of the cigarette pack 3 (the side with the word "Gutian" printed on it) faces upward during the conveyor belt 2, and then faces downward when the cigarette pack 3 is output from the bottom of the slide 4.

[0049] In some embodiments, the cigarette pack drop outlet 23 is located at one end of the conveyor belt 2 near the exit of the slide 4 along the width direction of the conveyor belt 2. Since the cigarette pack drop outlet 23 is located at one end near the exit of the slide 4, the first side of the cigarette pack 3 (the side with the word "Gutian" printed on it) faces upward during the conveying process on the conveyor belt 2, and it still faces upward when the cigarette pack 3 is output from the bottom of the slide 4.

[0050] See Figure 5 In other embodiments, the cigarette pack reversing device further includes a slide plate 6 located at the beginning of the conveyor belt 2 for conveying the cigarette pack 3 to the conveyor belt 2. The slide plate 6 is inclined relative to the horizontal direction, and the height of the slide plate 6 gradually decreases along the direction close to the inlet section of the conveyor belt 2 so that the cigarette pack 3 can move onto the conveyor belt 2 under the action of gravity.

[0051] In some embodiments, the first conveyor belt 21 includes a timing belt. The second conveyor belt 22 includes a longitudinal belt.

[0052] In some embodiments, the cigarette pack 3 is a cigarette pack comprising small cigarette packs arranged side by side. In other embodiments, the cigarette pack 3 is a boxed cigarette pack that directly packages cigarettes.

[0053] See Figure 5 This application discloses a method and apparatus for reversing the direction of cigarette packs; the equipment layout is shown below. Figure 1 It mainly consists of a slide plate 6, a synchronous belt (first conveyor belt 21), a longitudinal belt (second conveyor belt 22), and a side slide 4 for cigarette packs. The synchronous belt and the longitudinal belt are on the same horizontal plane and have the same speed. When the cigarette pack is sent from the slide plate 6 to the area above the synchronous belt and the longitudinal belt, it is powered by both belts. When the cigarette pack is sent to the reversing station, only the synchronous belt provides power. The longitudinal belt is in the open position (cigarette pack drop outlet 23) at this station. The cigarette pack rotates and is conveyed under its own weight, passing through the side slide 4. In this way, the cigarette pack can change from the top to the bottom and from the short side to the long side.

[0054] According to another aspect of the present invention, a cigarette packaging machine is also provided, which includes the above-described cigarette pack reversing device.

[0055] The above are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
