[0054] The elevator 13 is used to take the folding box 7 from the conveyor line or the first conveying mechanism 3 and lift it to the target height position. The lifting mechanism drives the transfer conveying mechanism to move to the target layer of the shelf 1. The conveyor line of the target layer works to send the folding box 7 to be shipped out to the transfer conveying mechanism. The lifting mechanism drives the transfer conveying mechanism to move to the height corresponding to the first conveying mechanism 3, and then the transfer conveying mechanism works to send the folding box 7 into the first conveying mechanism 3, realizing the shipping out of the folding line.

[0055] The lifting mechanism drives the transfer conveying mechanism to move to a height corresponding to that of the first conveying mechanism 3. The first conveying mechanism 3 sends the folding box 7 into the transfer conveying mechanism, and then the lifting mechanism drives the transfer conveying mechanism to be lifted to the target layer of the shelf 1. Then the transfer conveying mechanism sends the folding box 7 into the shelf 1. The conveyor line drives the folding box 7 into the target cargo position, thereby realizing the warehousing of the folding box 7.

[0056] The first conveying mechanism 3 adopts an existing bidirectional powered roller conveyor line and existing equipment, and its specific structure will not be described in detail here.

The second conveying mechanism 4 adopts the existing powered roller conveyor line. The head end of the second conveying mechanism 4 corresponds to the shipping station of the packaging machine 2. The packaging machine 2 sends the packaged cigarette packs into the second conveying mechanism 4, which is then sent out by the second conveying mechanism 4.

[0059] Preferably, the second conveying mechanism 4 adopts an existing powered roller conveyor line.

[0060] A cover opener 11 is provided between the RFID reader 9 and the bag taking station of the packaging machine. The first conveying mechanism 3 passes through the cover opener 11 . The cover opener 11 is used to unfold the box cover of the folding box 7 toward the packaging machine 2 side.

[0061] like Figure 4 As shown, the cover opener 11 is mounted on the first conveying mechanism, including a frame 1101, and the first conveying mechanism 3 passes through the frame. A fixed beam is provided on the top of the frame 1101, and a vertical lifting component is installed on the fixed beam. In this embodiment, the vertical lifting component adopts a lifting cylinder 1102 with a vertical axis. The cylinder body of the lifting cylinder 1102 is fixed on the fixed beam, and its piston rod is connected to the lifting plate 1103. The lifting plate 1103 is located directly above the first conveying mechanism 3.

[0062] Furthermore, the lifting plate 1103 is fixed to the bottom ends of the two guide columns, and the guide columns pass through the guide sleeves provided on the fixed beam and are slidably connected to the guide sleeves to guide the lifting movement of the lifting plate 1103.

[0063] An internal support assembly is provided on the upper surface of the lifting plate 1103 parallel to one side edge of the first conveying mechanism 3, and an external pressure assembly is provided on the opposite side edge. The internal support assembly is used to support the two box covers adjacent to the box cover to be unfolded from the inside of the folding box 7, and the external pressure assembly is used to press the two box covers adjacent to the box cover to be unfolded from the outside of the folding box 7, thereby achieving the fixation of the two box covers adjacent to the box cover to be unfolded.

[0064] The inner support assembly includes two first horizontal telescopic components, which are arranged at two ends of one side of the lifting plate 1103 and are coaxially arranged. The telescopic direction of the first horizontal telescopic components is parallel to the conveying direction of the first conveying mechanism 3.

[0065] In this embodiment, the first horizontal telescopic component adopts the first horizontal cylinder 1104, the cylinder body of the first horizontal cylinder 1104 is fixed on the upper surface of the lifting plate 1103, the piston rod of the first horizontal cylinder 1104 is connected to the inner support plate 1105, and the inner support plate 1105 is used to contact the inner surface of the box cover.

[0066] The external pressure assembly includes two second horizontal telescopic components, which are arranged at two ends of the other side of the lifting plate 1103 and are coaxially arranged. The telescopic direction of the second horizontal telescopic components is parallel to the conveying direction of the first conveying mechanism 3.

[0067] In this embodiment, the second horizontal telescopic component adopts a second horizontal cylinder 1106, the cylinder body of the second horizontal cylinder 1106 is fixed on the upper surface of the lifting plate 1103, and the piston rod of the second horizontal cylinder 1106 is connected to the outer pressure plate 1107, and the outer pressure plate 1107 is used to contact the outer surface of the box cover.

[0068] An expansion drive component is fixed between the two second horizontal cylinders 1106. The expansion drive component adopts the expansion drive cylinder 1108. The axis of the expansion drive cylinder 1108 is set horizontally and is perpendicular to the axes of the first horizontal cylinder 1104 and the second horizontal cylinder 1106.

[0069] The cylinder body of the deployment driving cylinder 1108 is fixed on the upper surface of the lifting plate 1103, and its piston rod is connected to the push plate 1109. The push plate 1109 is used to contact the box cover to be deployed and deploy the box cover under the drive of the deployment driving cylinder 1108.

[0070] The working method of the decapping machine 11 is:

[0071] The folding box 7 moves to the position directly below the lifting plate 1103. The lifting cylinder 1102 drives the lifting plate 1103 down to the set height. The first horizontal cylinder 1104 and the second horizontal cylinder 1106 are activated, driving the two inner support plates 1105 to contact the inner side surfaces of the two adjacent box covers to be unfolded, and driving the two outer pressure plates 1107 to contact the outer side surfaces of the two adjacent box covers to be unfolded, thereby securing the two adjacent box covers to be unfolded. The unfolding drive cylinder 1108 is activated, driving the push plate 1109 to push out, and the push plate 1109 pushes the box cover to be unfolded to unfold.

[0072] The provision of the cover opener 11 facilitates the bag taking mechanism of the packaging machine 2 to take out the packaging bags 8 from the folding box.

[0073] like Figure 5 As shown, the folding box 7 adopts a box structure with an open top, including a bottom box cover. The bottom box cover is a square box cover, and the four edges of the bottom box cover are rotatably connected to the side box covers 701, wherein a locking mechanism is provided between the corresponding ends of the top edges of two adjacent side box covers 701, so that when the folding box is in a folded and stowed state, the adjacent side box covers 701 can be locked and fixed.

[0074] The locking component is a snap-on locking component. Specifically, the top edge ends of the two oppositely arranged side box covers 701 are provided with a slot component 702. The slot component 702 is made of a flexible plastic material and is provided with a slot.

[0075] The ends of the top edges of the other two oppositely arranged side box covers 701 are provided with a card block component 703 made of flexible plastic material. The card block component 703 is provided with a card block that matches the card slot. When the four side box covers 701 are perpendicular to the bottom box cover, the card block is inserted into the corresponding card slot, thereby realizing the locking and fixation of the side box covers 701.

[0076] Furthermore, a side strip 704 is provided at the edge of the side box cover 701. The side strip 704 is made of plastic material, and a locking component is installed on the side strip.

[0077] Furthermore, the bottom box cover and the side box cover 701 are made of hollow PP board, which is light in weight and environmentally friendly.

[0080] Furthermore, an RFID chip 706 is provided inside one of the side box covers 7-1, and a number sticker and a bar code or a QR code is provided on the outer surface.

[0081] The packaging system also includes a transfer vehicle 6, which is a transfer AGV vehicle. The transfer AGV vehicle is used to deliver the packaged cigarette packs 18 at the end of the second conveying mechanism 4 to the delivery vehicle 17. The transfer AGV vehicle is also used to deliver the fully unfolded and stacked folding boxes 7 at the end of the first conveying mechanism 3 to the delivery vehicle 17, so that the folding boxes 7 and the cigarette packs 18 are delivered together with the vehicle.

[0082] At the end of the second conveying mechanism 4, the cigarette packs 18 are stacked onto the transfer AGV by manual stacking or robot stacking. At the end of the first conveying mechanism 3, the folding box 7 is fully unfolded manually and then stacked onto the transfer AGV.

[0083] In another embodiment, Figure 6 As shown, an unfolding platform is provided at the end of the first conveying mechanism 3, and a gantry is mounted on the unfolding platform. A horizontal two-axis linkage mechanism is provided on the top of the gantry. The horizontal two-axis linkage mechanism can use existing equipment, and its specific structure is not described in detail here. The horizontal two-axis linkage mechanism is connected to the stacking robot 14 through a lifting mechanism. The stacking robot 14 fully unfolds the folding box 7 and stacks it on the AGV vehicle.

[0084] In this embodiment, the end of the stacking robot 14 is provided with a tooling plate 1401, and a plurality of suction cups 1402 are provided on the tooling plate 1401. A cylinder is provided at the two edges of the tooling plate 1401 along the conveying direction of the first conveying mechanism 3. The axis of the piston rod of the cylinder is arranged along the conveying direction of the first conveying mechanism 3. The piston rod of the cylinder is provided with a push plate. When unfolding, the stacking robot 14 first uses the suction cup 1402 to transfer the folding box 7 to the unfolding platform 19, and when placing it, the side box cover that has been unfolded is placed on the unfolding platform 19. Under the action of the opening platform 19, it becomes horizontal. The suction cup 1402 first absorbs and fixes the side cover 701 on the opposite side of the unfolded side cover 701. The piston rod of the cylinder works to unfold the other two side covers through the push plate. Then the piston rod of the cylinder resets and the stacking robot 14 works to drive the side cover 701 connected to it to rotate outward to the set angle through the suction cup 1402. Then the suction cup 1402 releases the side cover, and the side cover 701 flips and unfolds under its own gravity. Then the stacking robot 14 stacks the unfolded folding box 7 on the transfer AGV through the suction cup 1402.

[0085] Furthermore, a labeling and photographing device 15 is provided behind the shipping station of the packaging machine 2. The labeling and photographing device 15 includes a labeling machine and an image acquisition component. The labeling machine can use existing equipment, and the image acquisition component can use an existing camera. The labeling machine is used to label the packaged cigarette packs on the second conveying mechanism 4, and the camera is used to collect images of the packaged cigarette packs.

[0086] Example 2

[0087] This embodiment provides a cigarette delivery system, including the cigarette packaging system described in Example 1, and also includes a delivery vehicle 17, which is used to receive cigarette packs 18 and fully unfolded and stacked folding boxes 7 delivered by the transfer AGV vehicle, and is used to deliver the cigarette packs 18 and folding boxes 7.

[0088] The delivery vehicle 17 can be an existing transport vehicle, which will not be described in detail here.

[0089] Example 3

[0090] This embodiment provides a working method of the cigarette dispensing system described in Example 2:

[0091] like Figure 8 As shown, the cigarette carton distribution and stacking machine 12 distributes and stacks the sorted cigarette carton cartons. The stacked cigarette stacks enter the packaging machine 2 through the cigarette stack conveyor mechanism. After receiving the folding box 7 containing the packaging bags 8, the transfer conveyor mechanism moves to a height corresponding to the first conveyor mechanism 3 and delivers the folding box 7 containing the packaging bags 8 to the first conveyor mechanism 3. The first conveyor mechanism 3 delivers the folding box 7 to the lid opener 11. The lid opener 11 unfolds the side box cover of the folding box 7 to open the folding box. The first conveyor mechanism 3 then conveys the folding box to the bag removal station of the packaging machine 2. The packaging machine 2 removes the bags. The bag removal mechanism of the packaging machine 2 removes the packaging bags 8 from the folding box 7. The packaging machine 2 uses the packaging bags 8 to package the cigarette stacks and push the cigarettes into bags. The packaged cigarette packs are delivered by the second conveyor mechanism 4. During the conveying process, they are labeled by the labeling machine and the camera captures images. The cigarette packs 18 at the end of the second conveyor mechanism 4 are stacked manually or by a robot on the transfer AGV vehicle.

[0092] The empty folding box 7 is transported to the end thereof by the first conveying mechanism 3 , and is fully unfolded manually or by a palletizing robot 14 , and then palletized on a transfer AGV.

[0093] like Figure 7 As shown, the transfer AGV delivers the cigarette packs 18 and the stacked folding boxes 7 to the delivery vehicle 17, and the cigarette packs 18 and the folding boxes 7 are delivered to the customer by the vehicle.

[0094] After the cigarette delivery is completed, the delivery staff collects the packaging bags 8 and folding boxes 7, and the folding boxes 7 and packaging bags 8 are sent back with the delivery vehicle 17. Then, the packaging bags 8 are manually placed in the folding boxes 7 and the folding boxes 7 are placed in the storage and warehousing conveying mechanism 5. In this embodiment, the folding boxes 7 can be stacked and placed on the cache station 16 on one side of the storage and warehousing conveying mechanism 5. The folding boxes 7 are stacked on the carrying pallet, and the storage and warehousing conveying mechanism 5 sends the folding boxes 7 to the first conveying mechanism 3. The first conveying mechanism 3 drives the folding boxes 7 to enter the RFID reader 9. The RFID reader 9 records the number of packaging bags 8 stored in each folding box 7, verifies whether the recovered number is accurate, and takes inventory of the in-and-out quantity. If qualified, they are sent to the transfer conveying mechanism by the first conveying mechanism 3, and then sent to the shelf 1 by the transfer conveying mechanism. The unqualified ones are sent to the detection and rejection conveying mechanism 10 by the transfer mechanism and sent out by the detection and rejection conveying mechanism 10.

[0095] In the distribution system and working method of this embodiment, the folding box 7 can be fully unfolded after the bag is taken out, and enters the distribution vehicle 17 together with the packaged cigarette packs 18 for distribution.
