The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0041] See also Figure 1A cigarette pack conveying device according to a specific embodiment of the present invention comprises a lifting device 1 and a first transfer device 2, wherein the lifting device 1 comprises a vertical support 11, a conveying mechanism 12, a driving assembly 13, and a carrying assembly 14, wherein the conveying mechanism 12 is vertically arranged on the vertical support 11, the driving assembly 13 is used to drive the conveying mechanism 12, and a plurality of carrying assemblies 14 are arranged on the conveying mechanism 12, wherein the carrying assemblies 14 are used to carry cigarette packs; the first transfer device 2 is arranged on the upper part of the lifting device 1, the lifting device 1 is used to vertically lift and transport cigarette packs, and the first transfer device 2 is used to receive cigarette packs vertically lifted to a higher position by the lifting device 1, and transfer the cigarette packs to the cigarette pack packaging production line.

[0042] For details, please refer to Figure 2 The conveying mechanism 12 includes two vertical conveyor belts arranged opposite to each other, and two pulley groups for driving each of the vertical conveyor belts, both pulley groups are connected to the driving assembly 13, and the two pulley groups are driven by the driving assembly 13 to run synchronously. In this embodiment, one pulley group includes two pulleys, the two pulleys are arranged vertically, a vertical conveyor belt is wound around the two pulleys, and the upper and lower pulleys are rotatably mounted on the vertical bracket 11.

[0043] Moreover, the driving component 13 includes a lifting motor, a worm wheel, and a worm. The worm is integrally arranged with the output rotating shaft of the lifting motor. The lifting motor is laterally fixedly installed at the upper end of the vertical bracket 11. A worm wheel is coaxially arranged on one side of the pulleys at the upper ends of the two pulley groups. The worm wheel is provided with two sets of worm teeth, and the two sets of worm teeth are inclined and symmetrical to each other. The lifting motor is connected to the two pulley groups through a worm gear mechanism at the upper end of the conveying mechanism 12. One lifting motor can drive the two pulleys to rotate at the same time. The rotation directions of the two pulleys are opposite. The relative inner sides of the two vertical conveyor belts can move upward synchronously, so that the loading component 14 can rise and move between the two vertical conveyor belts to achieve the purpose of lifting the cigarette packs.

[0044] Corresponding to this is: See Figure 2, multiple bearing bars are evenly spaced on the two vertical conveyor belts, and the multiple bearing bars on the two vertical conveyor belts are opposite to each other to form multiple carrying components 14. In this regard, when the bearing bars between the two vertical conveyor belts are driven to move from bottom to top, a cigarette pack can be supported by two opposite and mutually tangent bearing bars on the two vertical conveyor belts at the same time, and lifted and transported to the upper end of the vertical conveyor belts by the two bearing bars; when the cigarette pack is transported to the upper end of the lifting device 1 and transferred to the first transfer device 2, the two bearing bars of a carrying component 14 can be separated from each other, and the two bearing bars are respectively moved to the outer positions of the two vertical conveyor belts facing each other, and move downward until the two return to the lower ends of the relative inner positions of the two vertical conveyor belts again to support and transport the cigarette pack upwards.

[0045] In addition, in the present embodiment, two vertically movable adjustment blocks are provided at the lower part of the vertical bracket 11 corresponding to the position for setting the pulleys, and the pulleys at the lower ends of the two pulley groups are respectively provided on an adjustment block, so that the technician can adjust the tension of the vertical conveyor belt by adjusting the vertical position of the adjustment block, so that the two vertical conveyor belts are always kept in a tensioned state, ensuring that the lifting device 1 can operate normally.

[0046] It should be noted that: in order to further limit the cigarette packs and prevent them from falling from the carrier assembly 14, when the bearing bar is between the two vertical conveyor belts, an additional limiting bar is provided above each bearing bar, and the distance between each bearing bar and the limiting bar above it is just equal to the thickness of a cigarette pack, or slightly greater than the thickness of a cigarette pack. Moreover, along the axial direction of the pulley, limiting plates 15 are provided on both sides of the two vertical conveyor belts, and the limiting plates 15 on both sides are also located on both sides of the carrier assembly 14. The limiting plates 15 on both sides cooperate with each other to further limit the cigarette packs in the horizontal direction to prevent the cigarette packs from falling from the carrier assembly 14.

[0047] See also Figure 1 The first transfer device 2 is horizontally arranged at the upper end of the lifting device 1, and the first transfer device 2 is fixedly mounted on the upper end of the vertical bracket 11 through an additional mounting bracket.

[0048] See also Figure 3 and Figure 4 The first transfer device 2 includes a first driving motor 21, a first conveyor belt 22, a transfer guide rail 23, and a first cigarette pushing component 24; Figure 4Taking the shown orientation as an example, the first conveyor belt 22 is arranged horizontally, the left end of the first conveyor belt 22 extends between the two vertical conveyor belts, the pulley at the right end of the first conveyor belt 22 is connected to the first drive motor 21 through a belt, and a plurality of first cigarette pushing components 24 are equidistantly arranged on the first conveyor belt 22. The first cigarette pushing components 24 are two first convex strips fixedly arranged on the first conveyor belt 22, and the spacing between the two first convex strips is equivalent to the width of a cigarette pack. The transfer guide rail 23 is a straight guide rail, and the transfer guide rail 23 is arranged directly below the first conveyor belt 22. The extension direction of the transfer guide rail 23 is the same as the transmission direction of the first conveyor belt 22, and the left end of the transfer guide rail 23 abuts against the edge of the side wall of the vertical conveyor belt, and the left end of the transfer guide rail 23 is also located at the upper edge of the limit plate 15.

[0049] In this regard, in this embodiment, the technician turns on the first drive motor 21 to run the first conveyor belt 22 to drive a first cigarette pushing component 24 to move between the two vertical conveyor belts and to a downward position; at the same time, the lifting motor drives the carrier component 14 carrying the cigarette pack to move upward, and when the upper end surface of the carrier strip is flush with the upper end surface of the transfer guide rail 23, the cigarette pack is just lifted to the position between the two first convex strips; thereafter, the lifting motor stops running, and the first drive motor 21 drives the first cigarette pushing component 24 to move horizontally to the right from between the two vertical conveyor belts, and drives the cigarette pack to move right to the transfer guide rail 23, and then the lifting motor runs again to drive the next carrier component 14 and the cigarette pack to move upward, and the first drive motor 21 also drives the next first cigarette pushing component 24 to move again between the two vertical conveyor belts and to a downward position, thus forming a cycle, and realizing the operation of fully automatic lifting and conveying of cigarette packs and automatic transfer of cigarette packs from the top of the lifting device 1.

[0050] Generally speaking, Figure 4 Taking the position shown as an example, the right end of the transfer rail 23 can be directly extended to the cigarette packing production line, and the cigarette packs can be directly added to the cigarette packing production line when they fall out of the right end of the transfer rail 23. However, due to factors such as the installation method, since the length of the first transfer device 2 itself is not large, the full load conveying capacity of the entire cigarette pack conveying device is not high, resulting in it being unable to meet the large-volume cigarette pack conveying needs in the cigarette factory.

[0051] In this embodiment, please refer to Figure 1, a third conveyor belt 31 and a third drive motor 32 are also provided at the output end of the first transfer device 2. The structure of the third conveyor belt 31 is the same as that of the first conveyor belt 22, but the third conveyor belt 31 has a larger conveying length to effectively increase the full-load conveying capacity of the entire cigarette pack conveying device. Moreover, a fourth transfer device is also provided at the output end of the third conveyor belt 31. The fourth transfer device has the same structure as the first transfer device 2, except that one end of the fourth transfer device is provided above the output end of the third conveyor belt 31, the guide rail structure of the fourth transfer device abuts against the side end of the output end of the third conveyor belt 31, and the output end of the guide rail structure of the fourth transfer device extends to the cigarette pack packaging production line, and the cigarette packs are finally transferred and transported to the cigarette pack packaging production line via the fourth transfer device.

[0052] In this embodiment, the third conveyor belt 31 and the fourth transfer device are both fixed to external equipment of the production workshop through inclined mounting brackets.

[0053] For further information, see Figure 5 , Figure 6 , Figure 7 In this embodiment, a transfer storage bin 4 and a second transfer device 6 are also installed on the vertical support 11; an opening is provided at the upper end of the transfer storage bin 4, and multiple cigarette packs are stacked and stored in the transfer storage bin 4 from the opening above the transfer storage bin 4; an opening is also provided at the lower end of the transfer storage bin 4, and the second transfer device 6 is arranged between the lower end opening of the transfer storage bin 4 and the lifting device 1, and the second transfer device 6 is used to horizontally transfer the cigarette packs in the transfer storage bin 4 to the lower part of the lifting device 1 to feed the lifting device 1.

[0054] For details, please refer to Figure 5In this embodiment, the intermediate storage bin 4 includes a baffle 41, a side plate 42, a movable stop bar 43, a stop bar 44, a fixed plate 45, a cover plate 46 and a connecting piece 47. The baffle 41 is fixed to the side plate 42 with screws, the movable stop bar 43 is fixed to the connecting piece 47 with screws, the stop bar 44 is fixed to the side plate 42 with screws, the cover plate 46 is fixed to the fixed plate 45 with screws, and the connecting piece 47 is fixed to the side plate 42 with screws. The movable stop bar 43 and the stop bar 44 are both arranged on the other side of the side plate 42 where the baffle 41 is not connected. Thus, the baffle 41, the side plate 42, the movable stop bar 43 and the stop bar 44 form a material channel, and the cigarette packs placed in the material storage mechanism 4 can only move downward in the material channel and will not leave the material channel in any horizontal direction. When the operator places cigarette packs into the intermediate transfer storage bin 4, he can choose to first unscrew the screws on the movable stop bar 43 and rotate it downwards. When the total height of the cigarette packs placed is close to the height of the stop bar 44, the movable stop bar 43 is rotated back and fixed to the connecting piece 47 with screws, and then the cigarette packs are placed into the intermediate transfer storage bin 4; the cigarette packs can also be directly placed into the intermediate transfer storage bin 4 from the upper opening position; when the cigarette packs located at the bottom layer of the intermediate transfer storage bin 4 are transferred to the lifting device 1 by the second transfer device 6, the cigarette packs located at the upper layer of the intermediate transfer storage bin 4 can fall freely to be supplemented to the lower opening of the intermediate transfer storage bin 4.

[0055] In this embodiment, the operator only needs to put the cigarette packs into the transfer storage bin 4 regularly. The subsequent transfer of the cigarette packs can be completely achieved by the second transfer device 6, the lifting device 1, the first transfer device 2, the third conveyor belt 31, and the fourth transfer device, so as to effectively reduce the consumption of manpower and material resources and accurately control the material transportation time and demand.

[0056] See also Figure 6 and Figure 7 In this embodiment, the second transfer device 6 includes a second drive motor 61, a second conveyor belt 62, and a second cigarette pushing assembly 63. The second conveyor belt 62 is provided with a plurality of second cigarette pushing assemblies 63. The lower end of the intermediate transfer storage bin 4 is also provided with an opening. One end of the second conveyor belt 62 extends to the lower end opening of the intermediate transfer storage bin 4, and the other end extends to the lower end of the lifting device 1. The second drive motor 61 is used to drive the second conveyor belt 62 to operate, so that the second conveyor belt 62 drives the plurality of second cigarette pushing assemblies 63 to pass through the lower end opening of the intermediate transfer storage bin 4 in turn, and then the plurality of second cigarette pushing assemblies 63 push the cigarette packs out of the lower end of the intermediate transfer storage bin 4 in turn. The second cigarette pushing assembly 63 cooperates with the second conveyor belt 62 to transport the pushed-out cigarette packs to the lower part of the lifting device 1, so that the lifting device 1 can lift and transport the cigarette packs.

[0057] Specifically, the second transfer device 6 is fixedly mounted on the vertical support 11 through an additional mounting bracket, and the lower end of the second transfer device 6 is flush with the lower end of the transfer storage bin 4. Figure 7 Taking the shown orientation as an example, the right end of the second conveyor belt 62 extends to just below the lower opening of the transfer storage bin 4, the pulley at the left end of the second conveyor belt 62 is connected to the second drive motor 61 through a belt drive, the left end of the second conveyor belt 62 also extends between the two vertical conveyor belts of the lifting device 1 and is located at the lower part of the lifting device 1, and a plurality of second cigarette pushing assemblies 63 are equidistantly arranged on the second conveyor belt 62, and the second cigarette pushing assemblies 63 are two second convex strips fixedly arranged on the second conveyor belt 62, and the spacing between the two second convex strips is equivalent to the width of a cigarette pack.

[0058] In this regard, in this embodiment, the technician turns on the second drive motor 61 to run the second conveyor belt 62 to drive a second cigarette pushing component 63 to move to the lower end opening of the transfer storage bin 4, and makes the two second convex strips respectively located on both sides of the lower end opening of the transfer storage bin 4. At this time, the falling of the cigarette pack is not blocked by the second convex strip, and the cigarette pack at the bottom of the transfer storage bin 4 can just fall between the two second convex strips, and the cigarette pack is also driven by the second conveyor belt 62 to move toward the lifting device 1 until the cigarette pack and the second cigarette pushing component 63 are moved between the two vertical conveyor belts. At this time, the loading component 14 can lift and carry the cigarette pack from the second conveyor belt 62 when it moves upward driven by the vertical conveyor belt, so as to achieve the purpose of automatically transferring the cigarette pack from the transfer storage bin 4 to the lifting device 1.
