SUMMARY

[0004] The purpose of the present application is to provide a kind of full product specification piece cigarette conveying code disc device and method. The device and method can realize the rapid conveying of full product specification piece cigarette, thereby improving the production efficiency of enterprise.

[0005] The technical scheme of the present application: a kind of full product specification piece cigarette conveying code disc device, including piece cigarette conveying line, piece cigarette conveying line tail sequentially provided with transfer device A and transfer device B, the side of transfer device A and transfer device B is correspondingly provided with palletizing supply conveying line A and palletizing supply conveying line B respectively, the side of palletizing supply conveying line A and palletizing supply conveying line B is correspondingly provided with mutually parallel code disc conveying line A and code disc conveying line B, the tail of code disc conveying line is provided with shuttle system, frame is provided above two palletizing supply conveying lines and two code disc conveying lines, movable right-angle coordinate manipulator is arranged on the frame;

[0006] Palletizing supply conveying line A and palletizing supply conveying line B are both arranged on the same side of piece cigarette conveying line, and are arranged in parallel with each other;Code disc conveying line A and code disc conveying line B are arranged in the same direction;The shuttle system is only provided with one set, and is arranged vertically with two code disc conveying lines;

[0007] It also includes an empty pallet replenishment device, which includes an empty pallet conveyor line set on the side of and parallel to the pallet racking conveyor line A. A pallet unloading machine is set on the empty pallet conveyor line. A longitudinal conveyor line A is set between the side of the tail end of the empty pallet conveyor line and the side of the head end of the pallet racking conveyor line A. A longitudinal conveyor line B is set between the side of the head end of the other side of the pallet racking conveyor line A and the side of the head end of the pallet racking conveyor line B. Pallet transfer A, pallet transfer B and pallet transfer C are respectively set at the tail end of the empty pallet conveyor line, the head end of the pallet racking conveyor line A and the head end of the pallet racking conveyor line B.

[0008] The pallet conveyor line A and the pallet conveyor line B are located below the sides of the pallet replenishment conveyor line A and the pallet replenishment conveyor line B, respectively, and the longitudinal conveyor line B passes under the pallet replenishment conveyor line A and the pallet replenishment conveyor line B.

[0010] In the aforementioned full-specification cigarette conveying and palletizing device, the palletizing and replenishing conveyor line B is an edge-mounted inclined roller conveyor.

[0011] In the aforementioned full-size cigarette conveying and palletizing device, a cigarette blocking and rotating mechanism is provided on the side frame of the cigarette conveying line.

[0012] A method for conveying and palletizing cigarette packs of all specifications, the method being implemented using the aforementioned device, specifically: cigarette packs are placed on a cigarette pack conveyor line for conveying, and according to the different specifications of the cigarette packs, the cigarette packs are transferred to different palletizing and replenishment conveyor lines through different transfer devices. Then, a Cartesian coordinate robot arm grabs the cigarette packs and pallets them on an empty pallet on any palletizing conveyor line. After palletizing is completed, the palletized cigarette packs are transferred to a high-bay warehouse for storage through a shuttle system.

[0013] In the aforementioned method for conveying and palletizing cigarettes of all specifications, when the standard cigarettes, medium-sized cigarettes, slim cigarettes, and short cigarettes are moved to the transfer device A, the transfer device A transfers these cigarettes to the palletizing and replenishment conveyor line A, and then the cigarettes are flipped and centered by the cigarette flipping device and the clamping and centering mechanism; while other irregularly shaped cigarettes are transferred to the palletizing and replenishment conveyor line B by the transfer device B, and are automatically positioned to the side during the conveying process on the palletizing and replenishment conveyor line B.

Specific implementation methods

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] An embodiment of the present invention: A full-size cigarette pack conveying and palletizing device includes a cigarette pack conveying line 1. A transfer device A2 and a transfer device B3 are sequentially arranged at the tail of the cigarette pack conveying line 1. A palletizing replenishment conveying line A4 is arranged on the side of the transfer device A2. A palletizing replenishment conveying line B5 is arranged on the side of the transfer device B3. A palletizing palletizing replenishment conveying line A4 is arranged on the side of the palletizing replenishment conveying line A4. A palletizing palletizing replenishment conveying line B5 is arranged on the side of the palletizing palletizing replenishment conveying line B5. A shuttle system 8 is arranged at the tail of the palletizing palletizing conveying lines A6 and B7. A frame 9 is arranged above the two palletizing replenishment conveying lines and the two palletizing palletizing conveying lines. A movable Cartesian coordinate robot 10 is arranged on the frame 9.

[0022] Palletizing and replenishing conveyor lines A4 and B5 are both located to the right of the cigarette pack conveyor line 1 and are arranged parallel to each other. The palletizing tray conveyor lines A6 and B7 are arranged in the same direction, meaning they convey cigarettes in the same direction. Only one shuttle system 8 is provided, and it is perpendicular to both palletizing tray conveyor lines. This structural arrangement makes the entire device relatively compact and requires a small floor space.

[0023] The full-size cigarette packing and palletizing device also includes an empty pallet replenishment device. This device comprises an empty pallet conveyor line 11 positioned parallel to and on the side of the palletizing conveyor line A6. A pallet unpacking machine 12 is located in the middle of the empty pallet conveyor line 11. A longitudinal conveyor line A13 is positioned between the side of the tail end of the empty pallet conveyor line 11 and the side of the head end of the palletizing conveyor line A6. A longitudinal conveyor line B14 is positioned between the side of the head end of the other side of the palletizing conveyor line A6 and the side of the head end of the palletizing conveyor line B7. A pallet transfer device A15 is located at the tail end of the empty pallet conveyor line 11, a pallet transfer device B16 is located at the head end of the palletizing conveyor line A6, and a pallet transfer device C17 is located at the head end of the palletizing conveyor line B7. This structure allows empty pallets to be replenished to the palletizing conveyor lines A6 and B7 one by one.

[0024] The pallet conveyor lines A6 and B7 are located below the sides of the pallet replenishment conveyor lines A4 and B5, respectively. The longitudinal conveyor line B14 passes under the pallet replenishment conveyor lines A4 and B5. This structure ensures that when empty pallets are replenished to the pallet conveyor line B7 via the longitudinal conveyor line B14, there will be no interference with the pallet replenishment conveyor lines A4 and B5 above.

[0025] The palletizing and replenishing conveyor line A4 is a roller conveyor line. Its front end is equipped with a cigarette-turning device 18, and above the palletizing and replenishing conveyor line A4 behind the cigarette-turning device 18 is a clamping and centering mechanism 19. After the cigarettes produced by the cigarette factory are transported to the logistics sorting center, they are placed on the cigarette conveyor line 1 for conveying. The stacking methods used by the cigarette factory for different specifications of cigarettes are different, resulting in different placement methods of different specifications of cigarettes on the cigarette conveyor line 1. Moreover, since the sizes of various specifications of cigarettes are different, the processing methods of different specifications of cigarettes on the palletizing and replenishing conveyor line are also different. Specifically, the cigarette boxes for standard cigarettes, medium cigarettes, slim cigarettes, and short cigarettes are laid flat. In order to facilitate the Cartesian coordinate robot 10 to quickly grasp a large number of cigarettes, it is necessary to flip the cigarette boxes for standard cigarettes, medium cigarettes, slim cigarettes, and short cigarettes. When the cigarette packs placed flat are conveyed to the cigarette turning device 18, they are rotated 90° to an upright position by the cigarette turning device 18. The flipped cigarette packs continue to be conveyed forward to the clamping and centering mechanism 19. The clamping and centering mechanism 19 realizes the clamping and positioning of the cigarette packs so that the rectangular coordinate robot arm 10 can grasp the cigarette packs.

[0026] Other irregularly shaped cigarettes are transported via palletizing and replenishing conveyor line B5. Since these irregularly shaped cigarettes do not require box-flipping, a box-flipping mechanism is not needed on palletizing and replenishing conveyor line B5. However, a cigarette positioning device is still required. To achieve cigarette positioning with a simple structure, palletizing and replenishing conveyor line B5 is configured as a side-mounted inclined roller conveyor. During transport on palletizing and replenishing conveyor line B5, irregularly shaped cigarettes will automatically move along one side of the line until they are in contact with the side, thus achieving positioning. Palletizing and replenishing conveyor line A4 is not configured as a side-mounted inclined roller conveyor because the overall height of the cigarette boxes for standard and short cigarettes is relatively high after flipping. If a side-mounted inclined roller conveyor were used for positioning, to prevent the cigarettes from tipping over during transport, palletizing and replenishing conveyor line A4 would have to maintain a low conveying speed, which would severely limit the efficiency of palletizing and replenishing cigarettes.

[0027] To facilitate the subsequent gripping of cigarettes by the rectangular coordinate robot 10, when medium and slim cigarettes are conveyed on the cigarette conveyor line 1, their cigarette boxes need to be rotated by 90°, so that the long side of the cigarette box, which was originally aligned with the width direction of the cigarette conveyor line 1, becomes aligned with the short side of the cigarette box. Therefore, a cigarette blocking and rotating mechanism 20 is provided on the side frame of the cigarette conveyor line 1. When one side of the front long side of the cigarette box comes into contact with the cigarette blocking and rotating mechanism 20, the cigarette box will rotate under the blocking action of the cigarette blocking and rotating mechanism 20.

[0028] The present invention also protects a method for conveying and coding cigarettes of all specifications, which is implemented by means of the above-mentioned device.

[0029] Specifically, cigarette cases are placed on cigarette conveyor line 1 for transport. Depending on the cigarette type, different transfer devices transfer the cases to different palletizing and replenishing conveyor lines. Standard cigarettes, medium-sized cigarettes, slim cigarettes, and short cigarettes are transferred to transfer device A2, which then transfers them to palletizing and replenishing conveyor line A4. There, they are flipped and centered using cigarette flipping device 18 and clamping and centering mechanism 19. Other irregularly shaped cigarette cases are transported from transfer device A2 to transfer device B3, and then transferred to palletizing and replenishing conveyor line B5. During transport on palletizing and replenishing conveyor line B5, the cases are automatically positioned against the edge. After positioning, the cases are gripped by a Cartesian coordinate robot 10. This robot 10 can move linearly in multiple directions along frame 9 during gripping, facilitating the gripping of cigarettes while simultaneously palletizing them onto empty pallets on any palletizing conveyor line. After the cigarette cartons are palletized, they are transported to shuttle system 8 via a palletizing conveyor line. The pallets, along with the stacked cigarette cartons, are then transferred to shuttle system 8, which in turn transfers the stacked cigarette cartons to a high-bay warehouse for storage. While one palletizing conveyor line is transporting palletized cigarette cartons, the Cartesian coordinate robot 10 can palletize them onto an empty pallet on another palletizing conveyor line without interruption, thus improving the palletizing efficiency.

[0030] During the cigarette packing process, empty pallets can be replenished to the packing conveyor lines A6 and B7 via an empty pallet replenishment device. The specific replenishment method is as follows: several empty pallets stacked together will be conveyed from the head end of the empty pallet conveyor line 11 to the full pallet unpacking machine 12. For example, when conveying 10 empty pallets, the full pallet unpacking machine 12 will leave the bottom empty pallet on the empty pallet conveyor line 11, while the other 9 empty pallets will be clamped by the full pallet unpacking machine 12 and lifted to a certain height. After the bottom empty pallet is transferred to the pallet transfer A15, the 9 empty pallets will be placed on the empty pallet conveyor line 11. Then, the bottom empty pallet will be left on the empty pallet conveyor line 11, while the other 8 empty pallets will be clamped by the full pallet unpacking machine 12 and lifted to a certain height. This process is repeated to separate the stacked pallets into individual pallets and convey them to the tail end of the empty pallet conveyor line 11. Pallet transfer A then transfers the empty pallet to longitudinal conveyor line A13, which in turn transfers it to pallet transfer B16. If palletizing conveyor line A6 needs to replenish its empty pallet, it is transferred from pallet transfer B16 to palletizing conveyor line A6 and then moved to the palletizing station via palletizing conveyor line A6. If an empty pallet needs to be replenished to palletizing conveyor line B7, pallet transfer B16 transfers it to longitudinal conveyor line B14, which in turn transfers it to pallet transfer C17. Pallet transfer C17 then transfers the empty pallet to palletizing conveyor line B7 and moves it to the palletizing station via palletizing conveyor line B7.

[0031] The improvement of this invention lies in combining existing equipment with different functions according to requirements, thereby achieving the function of conveying and palletizing cigarettes of all specifications. It does not involve technical improvements to any specific device structure. The conveying device, transfer device, shuttle, robotic arm, pallet unpacking machine 12, cigarette turning device 18, clamping and centering mechanism 19, and cigarette blocking and rotating mechanism 20 used in the device structure of this invention all employ existing Changshu technology, therefore their specific structures will not be described in detail here. For example, the relevant technology of the pallet unpacking machine 12 is described in detail in patent CN201910671912.4; the cigarette turning device 18 can adopt the relevant technologies described in CN202420840196.4, CN202323525649.9, etc.; the clamping and centering mechanism 19 is described in detail in CN202410448936.4; and the cigarette blocking and rotating mechanism 20 is clearly described in patent CN2025223657863.
