Description

Technical Field

[0001] The present invention relates to the technical field of cigarette conveying equipment, and in particular to a cigarette pack conveying device for lifting and conveying cigarette packs and conveying the cigarette packs to supplement a cigarette pack production line. Background Art

[0002] During the cigarette packing process, when unqualified cigarette packs need to be discarded, gaps will be created; in addition, in order to reduce the floor space occupied by the cigarette pack production and packaging equipment, technicians will also set the cigarette pack conveying device between the cigarette pack production and packaging equipment above the cigarette pack production and packaging equipment to reduce the distance between each cigarette pack production and packaging equipment.

[0003] Affected by the above factors, when vacancies occur on the cigarette packaging production line due to the operation of rejecting unqualified cigarette packs, technicians need to add cigarette packs at a lower position to the cigarette pack conveying device at a higher position to fill the vacancies; however, in order to complete the replenishment work, technicians have to frequently walk between high and low positions, or bend over, which makes the technicians easily tired and affects the replenishment efficiency; moreover, at least one operator is required on each transportation line to complete the replenishment work, and the labor cost is also relatively high.

[0004] In this regard, a Chinese patent document discloses a cigarette pack refilling device (application number: 201921002319.2), which provides a cigarette pack refilling device for the cigarette packaging industry. The cigarette pack refilling device includes a bracket and a conveyor belt horizontally arranged on the bracket. The end of the conveyor belt is provided with a guide track.

[0048] Beneficial effects of the present invention:

[0049] A cigarette pack conveying device of the present invention achieves the purpose of vertically lifting and transporting cigarette packs by setting up an upright conveying mechanism and arranging multiple groups of carrying components on the conveying mechanism; at the same time, a first transfer device is installed on the upper part of the lifting device to meet the mechanized operation requirements of automatically conveying cigarette packs from a low place to a high place and orderly transferring the cigarette packs from the upper end of the lifting device to the cigarette pack packaging production line.

[0050] Moreover, on this basis, the present application further sets up a transit storage warehouse and a second transfer mechanism. Since the second transfer mechanism can automatically and orderly transfer the cigarette packs in the transit storage warehouse to the lifting device, the staff only needs to regularly replenish a specific number of cigarette packs to the transit storage warehouse, instead of standing by the lifting device and placing the cigarette packs one by one onto the loading assembly, so as to reduce the workload of the staff, further reduce production costs, and improve quality and efficiency.

[0066] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0067] See also Figure 1 A cigarette pack conveying device according to a specific embodiment of the present invention includes a lifting device 1 and a first transfer device 2. The lifting device 1 includes a vertical support 11, a conveying mechanism 12, a driving component 13, and a carrying component 14. The conveying mechanism 12 is vertically arranged on the vertical support 11. The driving component 13 is used to drive the conveying mechanism 12. The conveying mechanism 12 is provided with multiple carrying components 14, and the carrying components 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. 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.

[0068] For details, please refer to Figure 2 The conveying mechanism 12 includes two vertical conveyor belts arranged opposite each other, and two pulley assemblies for driving each of the vertical conveyor belts. Both pulley assemblies are in transmission connection with the driving assembly 13, and the two pulley assemblies operate synchronously under the drive of the driving assembly 13. In this embodiment, one pulley assembly includes two pulleys, which 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 support 11.

[0069] Moreover, the driving assembly 13 includes a lifting motor, a worm gear, and a worm. The worm gear is integrated with the output rotating shaft of the lifting motor. The lifting motor is fixedly installed horizontally at the upper end of the vertical bracket 11. A worm gear is coaxially arranged on one side of the pulleys at the upper ends of the two pulley groups. The worm gear 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 assembly 14 can rise and move between the two vertical conveyor belts to achieve the purpose of lifting the cigarette packs.

[0070] Corresponding to this is: See Figure 2 , multiple supporting bars are evenly spaced on both vertical conveyor belts, and the multiple supporting bars on the two vertical conveyor belts are opposite to each other in pairs, so as to form multiple carrier assemblies 14. In this regard, when the supporting bars between the two vertical conveyor belts are driven to move from bottom to top, a cigarette pack can be simultaneously supported by two opposing and mutually intersecting supporting bars on the two vertical conveyor belts, and lifted and transported upward by these two supporting bars to the upper end position of the vertical conveyor belts; 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 supporting bars of a carrier assembly 14 can be separated from each other, and the two supporting bars are respectively moved to the outer positions of the two vertical conveyor belts facing each other, and move downward until they return to the lower ends of the opposing inner positions of the two vertical conveyor belts to support and transport the cigarette pack upward again.

[0071] In addition, in this 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 set on an adjustment block, so that technicians 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.

[0072] It should be noted that to further limit the position of cigarette packs and prevent them from falling off the carrier assembly 14, when the support bars are located between the two vertical conveyor belts, an additional limit bar is installed above each support bar. The distance between each support bar and the limit bar above it is exactly the same as, or slightly greater than, the thickness of a cigarette pack. Furthermore, along the axis of the pulleys, limit plates 15 are installed on both sides of the two vertical conveyor belts. These limit plates 15 are also located on both sides of the carrier assembly 14. These limit plates 15 cooperate with each other to further limit the cigarette packs in the horizontal direction, preventing them from falling off the carrier assembly 14.

[0073] 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.

[0074] See also Figure 3 and Figure 4 The first transfer device 2 includes a first drive 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 by 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. 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. 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. 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 end edge of the limit plate 15.

[0075] To this end, in this embodiment, the technician turns on the first drive motor 21 to make the first conveyor belt 22 run, so as 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 loading component 14 carrying the cigarette pack to move upward, and when the upper end surface of the loading bar 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; after that, 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 to the right onto the transfer guide rail 23, and then the lifting motor runs again to drive the next loading component 14 and 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, which has realized the operation of fully automatic lifting and conveying cigarette packs and automatically transferring the cigarette packs from the top of the lifting device 1.

[0076] Generally speaking, Figure 4 Taking the illustrated orientation as an example, the right end of the transfer rail 23 can extend directly to the cigarette packaging production line, allowing cigarette packs to be directly added to the cigarette packaging production line when they fall out of the right end of the transfer rail 23. However, due to factors such as the installation method, the first transfer device 2 is relatively short, resulting in a low full-load capacity for the entire cigarette pack conveyor, making it unable to meet the large-volume cigarette pack conveying needs of the tobacco factory.

[0077] In this embodiment, please refer to Figure 1A 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 longer conveying length, effectively increasing the full-load conveying capacity of the entire cigarette pack conveying device. Furthermore, a fourth transfer device is 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 located above the output end of the third conveyor belt 31, and the guide rail structure of the fourth transfer device abuts the side end of the output end of the third conveyor belt 31. The output end of the guide rail structure of the fourth transfer device extends to the cigarette pack packaging production line, where the cigarette packs are ultimately transferred and transported to the cigarette pack packaging production line via the fourth transfer device.

[0078] In this embodiment, the third conveyor belt 31 and the fourth transfer device are both fixed to external equipment in the production workshop through inclined mounting brackets.

[0079] Further, 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 bracket 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 through 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 provided between the lower end opening of the transfer storage bin 4 and the lifting device 1. 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.

[0080] For details, please refer to Figure 5In this embodiment, the transit storage bin 4 includes a baffle 41, side panels 42, a movable stop bar 43, a stop bar 44, a fixed plate 45, a cover plate 46, and a connector 47. The baffle 41 is fixed to the side panels 42 with screws, the movable stop bar 43 is fixed to the connector 47 with screws, the stop bar 44 is fixed to the side panels 42 with screws, the cover plate 46 is fixed to the fixed plate 45 with screws, and the connector 47 is fixed to the side panels 42 with screws. The movable stop bar 43 and the stop bar 44 are both located on the other side of the side panel 42 that is not connected to the baffle 41. Thus, the baffle 41, side panels 42, movable stop bar 43, and stop bar 44 form a material channel, and cigarette packets placed in the material storage mechanism 4 can only move downward within the material channel and will not leave the material channel in any horizontal direction. When the operator places cigarette packs into the 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 transfer storage bin 4; the cigarette packs can also be directly placed into the transfer storage bin 4 from the upper opening position; when the cigarette packs located at the bottom layer of the transfer storage bin 4 are transferred to the lifting device 1 by the second transfer device 6, the cigarette packs located on the upper layer of the transfer storage bin 4 can fall freely to replenish the lower opening of the transfer storage bin 4.

[0081] In this embodiment, the operator only needs to regularly put the cigarette packs into the transfer storage warehouse 4. 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.

[0082] 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 multiple second cigarette pushing assemblies 63. The lower end of the 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 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 multiple second cigarette pushing assemblies 63 to pass through the lower end opening of the transfer storage bin 4 in turn, and then the multiple second cigarette pushing assemblies 63 push the cigarette packs out of the lower end of the transfer storage bin 4 in turn. The second cigarette pushing assembly 63 then 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.

[0083] 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, and 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. A plurality of second cigarette pushing assemblies 63 are equidistantly arranged on the second conveyor belt 62. 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.

[0084] To this end, 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 ridges 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 ridge, and the cigarette pack at the bottom of the transfer storage bin 4 can just fall between the two second ridges. Moreover, 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.
