[0002] The construction of existing cigarette conveying equipment for conveying regular cigarette packs is as follows: Figure 1 As shown. Figure 1 This is a cross-sectional view perpendicular to the cigarette conveying direction X. The conveyor belt 2 is mounted on the guide rail 3, and the regular cigarette pack 1 is placed on the conveyor belt 2. The conveyor belt 2 is driven by a motor (not shown) to move along the cigarette conveying direction X, thereby conveying the regular cigarette pack 1 along the X direction.

[0027] The present disclosure will now be described with reference to the accompanying drawings, which illustrate several embodiments of the present disclosure. However, it should be understood that the present disclosure can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure more complete and to fully illustrate the scope of protection of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. Furthermore, the drawings are merely illustrative of embodiments and are not necessarily drawn to scale.

[0028] It should be understood that the same reference numerals denote the same elements in all the accompanying drawings. The terminology used in this specification is for describing particular embodiments only and is not intended to limit this disclosure. All terms used in this specification (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0029] For ease of description, the following explanation will refer to the XYZ coordinate system, where the X direction is the direction of cigarette conveying, the Z direction is the vertical direction, and the Y direction is the horizontal direction that is perpendicular to both the X and Z directions.

[0030] The following reference Figures 3 to 6 The general construction of a cigarette flipping system according to embodiments of the present disclosure is described.

[0031] like Figures 3 to 6 As shown, the cigarette pack turning system of this disclosure includes a lifting device 100, a conveying device 200, and a turning device. The turning device includes a turning plate 300 and a guard plate 400. Both the lifting device 100 and the conveying device 200 convey cigarette packs along the X direction. The turning plate 300 and the guard plate 400 are fixed to the conveying device 200 and are opposite to each other in the Y direction. Figures 4 to 6As shown, in the YZ plane, the conveying device 200 defines a central axis OO extending in the Z direction. Hereinafter, the side closer to the central axis OO in the Y direction will be referred to as the inner side, and the side further away from the central axis OO will be referred to as the outer side. The conveying device 200 includes a guide section 201 for accommodating cigarettes in an upright position and a conveyor belt 202. The guide section 201 includes sidewalls 201A and 201B extending in the Z direction, and the conveyor belt 202 is disposed below the guide section 201. Mounting portions for mounting the tilting plate 300 and the guard plate 400 are arranged in pairs. Each mounting portion is L-shaped and includes first arms 203A and 203B extending in the Z direction and second arms 204A and 204B extending in the Y direction. The first arms 203A and 203B are located outside the sidewalls 201A and 201B, respectively. Elongated through holes extending in the Z direction are formed in the first arms 203A and 203B, and holes are formed in the second arms 204A and 204B.

[0032] The following reference Figures 4 to 8 Describe the details of the flipping device.

[0033] like Figures 4 to 7 As shown, the tilting plate 300 includes a first plate 301, a second plate 302, a third plate 303, and a tilting plate support 304. The first plate 301 is substantially perpendicular to the second plate 302, the third plate 303 is substantially perpendicular to the second plate 302, and the first plate 301 and the third plate 303 are substantially parallel. When the tilting plate 300 is fixed to the conveying device 200, the first plate 301 and the third plate 303 extend in the XZ plane, and the second plate 302 extends in the XY plane. Figures 4 to 6 In this structure, the first plate 301 is fixed to the second plate 302 at one end (outer end) in the Y direction and extends upward. The third plate 303 is fixed to the second plate 302 at the other end (inner end) in the Y direction and extends downward. The flip plate support 304 is L-shaped and includes a horizontal portion 305 and a vertical portion 306 that are perpendicular to each other. The vertical portion 306 is fixed to the outer surface of the third plate 303 and extends in the Z direction. The horizontal portion 305 extends from the middle of the third plate 303 in the Z direction in the Y direction and is fixed to the second arm 204B of the mounting portion. A long through hole 307 is provided in the horizontal portion 305, extending in the Y direction. A screw 308 passes through the through hole 307 and the hole in the second arm 204B to fix the horizontal portion 305 to the second arm 204B of the mounting portion. The first plate 301, the second plate 302, the third plate 303, and the flip plate support 304 can be welded together to form the flip plate 300, or they can be fixed in other ways or integrally formed to form the flip plate 300. It should be noted that, although in Figure 7 The flip-up plate support 304 is shown as two L-shaped members, but the number and shape of the flip-up plate support 304 are not limited to these. Figure 7 As shown, it is sufficient to fix the flip plate 300 to the mounting part.

[0034] like Figure 8 As shown, the guard plate 400 includes a fourth plate 401, a fifth plate 402, a sixth plate 403, and a guard plate support member 404. Figures 4 to 6 In the middle, the fourth plate 401 extends along the Z direction, and one end of the fifth plate 402 is fixed to the fourth plate 401 at the middle of the fourth plate 401 in the Z direction. The fifth plate 402 extends obliquely downward inward and forms an angle θ with the fourth plate 401. Figure 9 The sixth plate 403 extends vertically downward from the other end (lower end) of the fifth plate 402. The guard plate support 404 is L-shaped and includes a horizontal portion 405 and a vertical portion 406 that are perpendicular to each other. The vertical portion 406 is fixed to the outer surface of the fourth plate 401 and extends in the Z direction. The horizontal portion 405 extends in the Y direction and is fixed to the second arm 204A of the mounting portion. A long through hole 407 is provided in the horizontal portion 405, extending in the Y direction. Screws 408 pass through the through hole 407 and the hole in the second arm 204A to fix the horizontal portion 405 to the second arm 204A of the mounting portion. The fourth plate 401, the fifth plate 402, the sixth plate 403 and the guard plate support 404 can be welded together to form the guard plate 400, or they can be fixed in other ways or integrally formed to form the guard plate 400. It should be noted that, although in Figure 8 The center guard plate support 404 is shown as two L-shaped pieces, but the number and shape of the guard plate support 404 are not limited to these. Figure 8 As shown, it is sufficient to fix the guard plate 400 to the mounting part.

[0035] The first arms 203A and 203B of the mounting section can be fixed to the conveying device 200 with screws. For example... Figures 4 to 6 As shown, screws pass through the elongated through holes on the first arms 203A and 203B and the holes on the conveying device 200 to fix the mounting part to the conveying device 200.

[0036] The following reference Figure 9 , Figure 10 Describe the main dimensional relationships of the cigarette flipping system.

[0037] like Figure 10As shown, the length D1 of the cigarette pack 500 in the X direction is greater than the distance D2 between the end of the lifting device 100 and the second plate 302, so as to ensure that before the rear end of the cigarette pack 500 in the X direction leaves the lifting device 100, the front end of the cigarette pack 500 can be smoothly conveyed onto the second plate 302 and supported by the second plate 302. In addition, the turning plate 300 and the guard plate 400 can be deflected outward near the end of the lifting device 100 in the X direction to form a flared shape, so that the cigarette pack can be more smoothly conveyed onto the second plate 302.

[0038] As Figure 9 shown, in the flat state, the length of the cigarette pack 500 in the Y direction is a, the length in the Z direction is b, and the horizontal distance between the two vertical side walls 201A and 201B of the guiding part 201 of the conveying device 200 is c, and a > c > b. When a < c, the cigarette pack 500 can be directly conveyed by the conveying device 200 in the flat state without being turned over, as Figure 1 shown.

[0039] The length of the first plate 301 in the Z direction is L1, and the length of the second plate 302 in the Y direction is L2. L1 > b, preferably L1 = b + 2 mm. In order to make the cigarette pack automatically turn over when lying flat on the second plate 302, L2 < a / 2, so that the center of gravity of the cigarette pack falls inside the second plate 302, and a moment for turning over along the R direction is generated on the cigarette pack due to the action of the gravity G ( Figure 9 ). Preferably, L2 = a / 3, so that the cigarette pack can obtain sufficient support from the second plate 302 before completely leaving the lifting device 100, and the smooth turning over of the cigarette pack can be achieved after the cigarette pack completely leaves the lifting device 100.

[0040] The distance between the first plate 301 and the fourth plate 401 in the Y direction is L3, and the distance between the sixth plate 403 and the third plate 303 in the Y direction is L4, L3 > a > c > L4 > b. Preferably, a + 8 mm ≤ L3 ≤ a + 10 mm, b + 2 mm ≤ L4 ≤ b + 5 mm. The distance between the second plate 302 and the top surface of the conveyor belt 202 in the Z direction is H, H > a. Preferably, a + 2 mm ≤ H ≤ a + 3 mm, so as to reduce the impact force during falling while ensuring sufficient turning over of the cigarette pack. The included angle between the fifth plate 402 and the fourth plate 401 is θ, preferably, θ ≤ 30°, so as to improve the stability of turning over during the turning over process of the cigarette pack. Due to the above size settings, it can be ensured that the cigarette pack is conveyed in an upright state after the turning over of the cigarette pack is completed.

[0041] Because elongated through holes 307 and 308 extending in the Y direction are respectively provided on the horizontal portions 305 and 405, the fixed positions of the tilting plate 300 and the guard plate 400 in the Y direction are adjustable. Because elongated through holes (not shown) extending in the Z direction are respectively provided on the first arms 203A and 203B of the mounting portion, the fixed positions of the mounting portion, the tilting plate 300, and the guard plate 400 in the Z direction are adjustable. Therefore, the position of the tilting device fixed to the conveying device 200 can be adjusted in both the Y and Z directions, thereby accommodating cigarette strips 500 of various widths. In other words, Figure 9 Dimensions L3, L4, and H are all adjustable. For example, when the dimension 'a' of the cigarette pack 500 is large, the tilting plate 300 and the guard plate 400 can be moved away from each other when they are fixed to the mounting part, and the fixed position of the mounting part can be moved upward when it is fixed to the conveying device 200, thereby satisfying L3>a and H>a. With such a tilting device structure, existing conveying devices can be used to convey cigarette packs of various sizes, saving costs.

[0042] The following reference Figures 3 to 6 and Figure 10 Describe the process of automatically flipping 500 packs of cigarettes using a cigarette flipping system.

[0043] Overall, as shown in the figure, the cigarette pack 500 is conveyed in a horizontal position from the lifting device 100 along the X direction to the second plate 302 of the tilting plate 300. Figure 3 , 4 10), flipped from the flip plate 300 ( Figure 5 ), and then fell onto the conveyor 200. Figure 6 This allows the object to flip from a flat position to an upright position.

[0044] Specifically, firstly, the cigarette pack 500 is lifted by the lifting device 100 to a height higher than the conveying device 200, and the bottom surface of the cigarette pack 500 is flush with or slightly higher than the upper surface of the second plate 302.

[0045] Next, during the process of conveying the cigarette pack 500 from the lifting device 100 to the second plate 302, since D1>D2 and the bottom surface of the cigarette pack 500 is flush with or slightly higher than the top surface of the second plate 302, the leading edge of the cigarette pack 500 in the X direction is smoothly conveyed from the lifting device 100 to the second plate 302. At this time, the cigarette pack 500 is in a flat state and continues to be conveyed along the X direction by the lifting device 100.

[0046] After the rear end of the cigarette pack 500 detaches from the lifting device 100 in the X direction, the cigarette pack 500 is completely supported by the second plate 302. At this time, due to the overturning torque generated by gravity G in the R direction, the cigarette pack 500 overturns in the R direction. Due to the dimensional settings described above, after contacting the guard plate 400, the cigarette pack 500 falls between the third plate 303 and the sixth plate 403, and is placed upright on the guide section 201, and continues to be conveyed in the X direction by the conveyor belt 202, as... Figure 6 and Figure 3 As shown. At this point, the flipping process of the 500 pack of cigarettes is complete.

[0047] As described above, in the cigarette tumbling system according to this disclosure, a simple tumbling device consisting of a fixed tumbling plate 300 and a guard plate 400 is used to automatically tumble the cigarettes, eliminating the need for rollers, motors, and other devices, thus saving costs. The cigarettes tumble only under the influence of gravity, and the force exerted upon collision with the guard plate 400 and the conveying device 200 is small, preventing them from being squeezed by the components and better protecting the cigarettes during the tumbling process.

[0048] Furthermore, since elongated through holes are provided on the tilting plate 300, the guard plate 400, and the mounting part, the fixed position of the tilting device can be adjusted in the Y and Z directions, enabling the use of existing conveying devices to transport cigarette packs of various sizes.

[0049] The foregoing has described one embodiment of this disclosure, but it should be understood that this disclosure is not limited thereto. Various modifications will be conceived by those skilled in the art without departing from the scope of this disclosure.

[0050] For example, in the embodiments described above, screws are used to secure the flipping device to the mounting portion and the mounting portion to the conveying device; however, this is not necessary. Any other suitable securing method is conceivable.

[0051] For example, in the embodiments described above, the tilting plate is provided with a tilting plate support; however, this is not necessary. It is conceivable to directly fix the third plate to the conveying device, thus eliminating the need for the tilting plate support.

[0052] For example, in the embodiments described above, the guard plate is provided with a guard plate support; however, this is not necessary. It is conceivable to directly fix the fourth plate to the conveying device, thus eliminating the need for the guard plate support.

[0053] For example, in the embodiments described above, the mounting part is fixed to the conveying device by screws. It is conceivable that the mounting part can be integrally provided with the conveying device, or integrally provided with the tilting device, or the mounting part can be omitted and the tilting device can be directly fixed to the conveying device.

[0054] For example, in the embodiments described above, L2

[0055] Those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope of this disclosure.
