[0002] In the cigarette production process, the only equipment currently available on the market is the automatic feeding system for high-speed small box packaging machines. This system is placed on the ground, occupies a large area, and can only automatically feed small box label paper, with low feeding efficiency.

[0003] The market has a large number of general-purpose medium-speed packaging machines that lack automatic feeding, unpacking, and unloading devices. Typical small-box packaging machines rely on manual feeding. During production, small box label sheets are stacked in groups of five, resulting in rapid consumption. Frequent manual unpacking, handling, and reloading are necessary to replenish the machine's hopper and maintain production. Currently, operators must constantly monitor the machine's buffer and operating status, manually reloading repeatedly to keep it running.

[0040] like Figures 1-14 As shown, the small box unpacking and replenishing device provided in this embodiment includes: a high-altitude buffer conveying mechanism 1 disposed above the small box packaging machine for buffering the small box label paper; a vertical shifting mechanism 2 that can move vertically is disposed at one end of the high-altitude buffer conveying mechanism 1; a horizontal shifting mechanism 3 that can move horizontally is disposed on the right side of the bottom end of the vertical shifting mechanism 2; a lifting unpacking mechanism 5 disposed above the horizontal shifting mechanism 3 for unpacking the kraft paper on the small box label paper; a lifting kraft paper recycling mechanism 4 disposed below the unpacking mechanism 5 for recycling the unpacked kraft paper; a receiving platform 7 disposed below the horizontal shifting mechanism 3 and the kraft paper recycling mechanism 4; and a lowering mechanism 6 disposed between the horizontal shifting mechanism 3 and the unpacking mechanism 5 for placing the unpacked small box label paper on the small box packaging machine.

[0041] The high-altitude buffer conveyor 1 is mounted on a bracket. Specifically, the high-altitude buffer conveyor 1 includes several conveyor belts arranged sequentially along the horizontal direction, such as... Figure 1 and Figure 2As shown, in this invention, there are two conveyor belts. It should be noted that this invention does not specifically limit the number and length of the conveyor belts. After the RGV trolley transports the small box label paper 8 to its position, it is handed over to the conveyor belt. The small box label paper 8 can be transported and buffered on the conveyor belt. In specific implementation, each conveyor belt is selected according to the general external dimensions of the small box label paper 8 to meet the needs of various specifications and shapes of small box label paper 8. The buffer amount and conveying of the label paper can be controlled by the operation of the belt conveyor. The number of conveying components can be freely increased or decreased according to the relative distance between the small box packaging machine and the RGV conveyor line. In this invention, the conveyor belt adopts a modular design, which is convenient for installation. When the downstream small box packaging machine issues a material request, the conveyor belt transports the small box label paper 8 to the vertical shifting mechanism 2 and hands it over to the vertical shifting mechanism 2.

[0042] Furthermore, the receiving platform 7 is equipped with rollers to facilitate the sliding of the small box label paper 8 on the receiving platform 7 without scratching the small box label paper 8. Figure 2 As shown, the receiving platform 7 is located at the rear end of the vertical shifting mechanism 2 to receive the small box label paper 8 conveyed from the vertical shifting mechanism 2. The unsealing mechanism 5 is located above the receiving platform 7, and the kraft paper recycling mechanism 4 is located at the rear end of the receiving platform 7 to complete the unsealing and recycling of kraft paper on the receiving platform 7.

[0043] During operation, the five stacks of small box label paper 8 are transported by the RGV trolley to the high-altitude buffer conveyor 1 for buffering. When the small box packaging machine below consumes a certain amount, the small box label paper 8 buffered at the top will enter the vertical shifting mechanism 2 one stack at a time. The lifting component of the vertical shifting mechanism 2 will transport one stack of small box label paper 8 to the lower layer. The horizontal shifting mechanism 3 moves onto the lifting component, clamps the small box label paper 8 and transports it to the receiving platform 7. Then, the unsealing mechanism 5 and the kraft paper recycling mechanism 4 work to complete the unsealing and recycling of the kraft paper. Then, the horizontal shifting mechanism 3 transports the unsealed small box label paper 8 to the lowering mechanism 6. Finally, the lowering mechanism 6 places the small box label paper 8 on the small box packaging machine.

[0044] Furthermore, such as Figure 3As shown, the vertical shifting mechanism 2 includes: a linear module 21 arranged vertically; a first slider 22 that can slide vertically along the linear module 21 on its right side; a lifting back plate 23 on the right side of the first slider 22; a lifting baffle 24 on the right side of the lifting back plate 23; and a lifting support plate 26 arranged horizontally on the right side of the lifting baffle 24. The upper surface of the lifting support plate 26 can be moved to be flush with the upper surface of the high-altitude buffer conveying mechanism 1. The lifting support plate 26 is provided with several pulleys 27 to facilitate the sliding of the small box label paper 8 onto the lifting baffle 24. The linear module 21 is mounted on a corresponding support assembly.

[0045] Furthermore, the lifting back plate 23 is mounted on the first slider 22 by screws, and the lifting baffle 24 is connected to the lifting back plate 23 by the first stud 28; a lifting bracket 25 is provided below the lifting support plate 26 to support the lifting support plate 26, and the lifting bracket 25 is fastened to the lifting baffle 24 to support the lifting support plate 26; and the lifting support plate 26 is connected to the lifting baffle 24. In this invention, the lifting assembly is composed of the lifting back plate 23, the lifting baffle 24, the lifting bracket 25, the lifting support plate 26, the pulley 27, and the first stud 28. The entire lifting assembly can move up and down along the linear module 21 with the first slider 22. When the small box label paper 8 is conveyed to the end of the high-altitude buffer conveying mechanism 1, the lifting assembly rises, so that the upper plane of the lifting plate 26 moves to be flush with the upper surface of the high-altitude buffer conveying mechanism 1. The small box label paper 8 is slid into the lifting plate 26 by the movement of the conveyor belt. When the small box label paper 8 slides on the pulley 27 and gets close to the lifting baffle 24, the conveyor belt stops moving, and the small box label paper 8 moves vertically downward with the entire lifting assembly.

[0046] Furthermore, such as Figures 4-8 As shown, the horizontal shifting mechanism 3 includes a first horizontal shifting mechanism 31 and a second horizontal shifting mechanism 32 arranged opposite to each other, with the second horizontal shifting mechanism 32 located to the lower right of the first horizontal shifting mechanism 31. The receiving platform 7 and the kraft paper recycling mechanism 4 are sequentially arranged between the first horizontal shifting mechanism 31 and the second horizontal shifting mechanism 32. The unsealing mechanism 5 is located above the first horizontal shifting mechanism 31, and the lowering mechanism 6 is located above the second horizontal shifting mechanism 32.

[0047] Specifically, the first horizontal displacement mechanism 31 includes two first linear guide rails 311 arranged parallel to each other in the horizontal direction, and a first mounting plate 312 is provided between the two first linear guide rails 311; two second linear guide rails 315 arranged side by side in the vertical direction are provided above the first mounting plate 312; each second linear guide rail 315 is provided with a left clamping plate 313 and a right clamping plate 314 for clamping the small box label paper. The first linear guide rails 311 are supported on the base plate by second studs, and the first mounting plate 312 is connected to the slider of the first linear guide rail 311 by screws and can move with the slider of the first linear guide rail 311; the left clamping plate 313 and the right clamping plate 314 are respectively directly fixed to the slider of the second linear guide rail 315 by screws, and can clamp and release the material as the slider of the second linear guide rail 315 moves. The left clamp 313 and the right clamp 314 are designed according to the shape of the small box trademark paper 8. They can fit the shape of the small box trademark paper 8, clamp the dovetail groove and the front protrusion of the small box trademark paper 8, and will not damage the dovetail groove at the tail of the small box trademark paper 8.

[0048] Furthermore, the second horizontal displacement mechanism 32 includes two parallel third linear guide rails 322, on which a second mounting plate 321 is mounted. Two vertically aligned mounting side plates 327 are mounted on the second mounting plate 321, and mounting baffles 323 are mounted on the two mounting side plates 327. Two mounting supports 324 are mounted at the bottom end of the mounting baffles 323. Specifically, the mounting supports 324 are fixed to the mounting baffles 323 by screws. A first linear cylinder 328 is mounted on the back of the mounting baffles 323, and the first linear cylinder 328 is located between the two mounting side plates 327. A pressure block frame 326 is mounted on the push rod of the first linear cylinder 328, and a pressure block 325 is mounted on the pressure block frame 326. The third linear guide rail 322 is mounted on the base plate via a third stud. The second mounting plate 321 is fixedly connected to the slider of the third linear guide rail 322 and can move with the movement of the slider of the third linear guide rail 322. Each mounting side plate 327 and the mounting baffle 323 are perpendicular to the second mounting plate 321, and each mounting side plate 327 is perpendicular to the mounting baffle 323. Two mounting brackets 324 are parallel to each other and fixed to the mounting baffle 323 with screws. The two mounting brackets 324 and the two mounting side plates 327 are respectively arranged on both sides of the mounting baffle 323. The cross-section of the two mounting brackets 324 is a right triangle, with one right-angled side parallel to the third linear guide rail 322 and the other right-angled side attached to the side wall of the mounting baffle 323.

[0049] In its implementation, after the small box of label paper 8 is conveyed to the bottom layer by the lifting component of the vertical shifting mechanism 2, the first horizontal shifting mechanism 31 moves along the first linear guide rail 311 toward the vertical shifting mechanism 2. Subsequently, the second linear guide rail 315 operates, driving the left clamping plate 313 and the right clamping plate 314 to move toward the small box of label paper 8, clamping the small box of label paper 8 and stacking it. After clamping the material, the first horizontal shifting mechanism 31 moves toward the unsealing mechanism 5 to complete the unsealing of the kraft paper. After the small box of label paper 8 is unsealed, the first horizontal shifting mechanism 31 continues to move backward. At this time, the second horizontal shifting mechanism 32 moves toward the first horizontal shifting mechanism 31 and conveys the material to the mounting plate 324, which is close to the mounting baffle 323. At this time, the push rod of the first linear cylinder 328 retracts, causing the pressure block frame 326 to descend, so that the pressure block 325 presses down on the unsealed small box of label paper 8 to prevent the unsealed small box of label paper 8 from scattering. Then, the second horizontal shifting mechanism 32 moves toward the lowering mechanism 6 and moves to the bottom of the lowering mechanism 6 to hand over the small box of label paper 8 to the lowering mechanism 6.

[0050] Furthermore, such as Figure 9 and Figure 10 As shown, the kraft paper recycling mechanism 4 includes a mounting base plate 491. Mounting back plates 492 are symmetrically arranged on both sides above the mounting base plate 491. Mounting side plates 493 are arranged between the two mounting back plates 492. Both mounting back plates 492 and the mounting side plates 493 are perpendicular to the mounting base plate 491. The mounting base plate 491, mounting back plates 492, and mounting side plates 493 form a lifting assembly. Second linear cylinders 41 are respectively arranged at the top outer edges of the two mounting side plates 493, and a second roller 46 is arranged between the two mounting side plates 493. A recycling bin 42 is arranged below the mounting base plate 491 for recycling opened kraft paper. Paper; a first roller 43 is provided above the mounting base plate 491 and is installed below the receiving platform 7. An arc-shaped guide plate 44 extending into the recycling bin 42 is provided at the lower front end of the mounting base plate 491. The guide plate 44 is connected to the mounting base plate 491. A first suction cup frame is provided on the mounting base plate 491. The first suction cup frame is perpendicular to the mounting base plate 491, and the first suction cup frame and the mounting back plate 492 are located on opposite sides of the mounting base plate 491. A first vacuum suction cup 45 is installed on the first suction cup frame. A first guide rod 47 and a third linear cylinder 48 are provided below the mounting base plate 491.

[0051] In its implementation, the first guide rod 47 and the third linear cylinder 48 are mounted on the lifting assembly to control the operation of the entire lifting assembly. When the horizontal shifting mechanism 3 moves towards the vertical shifting mechanism 2, the third linear cylinder 48 starts working, pushing the kraft paper recycling mechanism 4 upward so that the mounting base plate 491 is flush with the receiving platform 7. After the horizontal shifting mechanism 3 transports the small box label paper 8 to the receiving platform 7, the unsealing mechanism 5 starts working, and at the same time, the second linear cylinder 41 works, pushing the first suction cup frame towards the material direction, so that the first vacuum suction cup 45 adsorbs the lower half of the small box label paper 8. After the suction is tight, the second linear cylinder 41 retracts, assisting the unsealing mechanism 5 in pulling the kraft paper out of the gap. When the unsealing mechanism 5 completes its work, the third linear cylinder 48 returns to the stop position, and the second linear cylinder 41 pushes again towards the small box label paper 8, activating the first roller 43 and the second roller 46, and the first vacuum suction cup 45 stops working. At the same time, the second horizontal shifting mechanism 32 moves towards the receiving platform 7. After it reaches the receiving platform 7, it picks up and presses the unsealed small box label paper 8, and moves towards the descending mechanism 6. At this time, the first roller 43 and the second roller 46 roll the kraft paper into the recycling box 42 along the guide plate 44, completing the work.

[0052] Furthermore, such as Figure 11 and Figure 12 As shown, the unpacking mechanism 5 includes a third mounting plate 56 mounted on a bracket. A first lifting plate 57 is provided on the outer side of the third mounting plate 56. A fourth linear cylinder 51 and second guide rods 52 located on both sides of the first lifting plate 57 are provided above the first lifting plate 57. Specifically, the cylinder bodies of the fourth linear cylinder 51 and the second guide rods 52 are both mounted on the third mounting plate 56 through connecting plates. The sliders of the fourth linear cylinder 51 and the second guide rods 52 are connected to the first lifting plate 57 to control the movement of the first lifting plate 57. A fourth linear guide rail 53 is also provided above the first lifting plate 57. A knife holder 541 is provided below the slider of the fourth linear guide rail 53. A cutter 542 is provided on the knife holder 541. The cutter 542 and the knife holder 541 can move from the initial position to the end position with the slider of the fourth linear guide rail 53, and then return from the end position to the initial position to complete a working process. A linear cylinder push rod 55 is provided below the third mounting plate 56. Specifically, the linear cylinder push rod 55 is connected to the first lifting plate 57 through the mounting plate and the mounting side plate. A second suction cup frame 59 is provided on the linear cylinder push rod 55. A second vacuum suction cup 58 is installed on the second suction cup frame 59, and the second vacuum suction cup 58 is located below the first lifting plate 57, that is, the second vacuum suction cup 58 is installed on the first lifting plate 57 and the second suction cup frame 59. The back of the second suction cup frame 59 is fixedly connected to the linear cylinder push rod 55 and moves by the movement of the linear cylinder push rod 55.

[0053] In its implementation, after the small box label paper 8 is transported to the receiving platform 7 by the first horizontal shifting mechanism 31, the fourth linear cylinder 51 of the unsealing mechanism 5 starts working, and the unsealing mechanism 5 begins to descend until the second vacuum suction cup 58 on the first lifting plate 57 presses the kraft paper on the small box label paper 8 and starts. At this time, the linear cylinder push rod 55 pushes the second suction cup frame 59 to move towards the small box label paper 8 until the second vacuum suction cup 58 on the second suction cup frame 59 presses and adsorbs the kraft paper on the small box label paper 8. Then, the linear cylinder push rod 55 moves away from the small box label paper 8, pulling the kraft paper out of the gap. At the same time, the first vacuum suction cup 45 of the kraft paper recycling mechanism 4 moves backward to assist the second vacuum suction cup 58 in pulling out the gap. After the gap is opened, the knife holder 541 and cutter 542 mounted on the slider of the fourth linear guide 53 move from the initial position to the end position along with the slider, causing the cutter 542 to cut the kraft paper through the opened gap. Then, it returns from the end position to the initial position, completing the unpacking action. Afterwards, the second vacuum suction cup 58 stops working, and the fourth linear cylinder 51 returns upward to the stop position, completing the entire workflow.

[0054] Furthermore, such as Figure 13 and Figure 14 As shown, the lowering mechanism 6 includes a fifth linear cylinder 61 mounted on the third mounting plate 56 and a third guide rod 62 arranged around the fifth linear cylinder 61. Both the fifth linear cylinder 61 and the third guide rod 62 are connected to the third mounting plate 56. A second lifting plate 63 is located below the fifth linear cylinder 61 and the third guide rod 62, with one end of the fifth linear cylinder 61 and the third guide rod 62 mounted above the lifting plate 63. A sixth linear cylinder 64 is located below the second lifting plate 63, and connecting plates 68 are located on both sides of the sixth linear cylinder 64. Specifically, the push rod of the sixth linear cylinder 64 is mounted on the connecting plate 68 by screws. A connecting shaft 67 is located below each connecting plate 68, and a left gripper 65 and a right gripper 66 are located below each connecting shaft 67. A base plate is located at the bottom of the left gripper 65 and the right gripper 66, which can support the dovetail groove and protrusion of the small box label paper 8. Figure 14 As shown, one end of the connecting shaft 67 is mounted on the connecting plate 68, and the other end is connected to the left gripper 65 and the right gripper 66.

[0055] In practice, after the small box of label paper 8 is unsealed, it is transported to the second horizontal shifting mechanism 32 and then conveyed to the area below the lowering mechanism 6. The second lifting plate 63 of the lowering mechanism 6 is lowered by the operation of the fifth linear cylinder 61, lowering the left gripper 65 and the right gripper 66 to the height of the mounting plate 324 of the second horizontal shifting mechanism 32. At this time, the sixth linear cylinder 64 begins to retract, driving the connecting plate 68, connecting shaft 67, left gripper 65, and right gripper 66 to move towards the unsealed small box of label paper 8, so that the left gripper 65 and the right gripper 66 clamp the small box of label paper 8. Subsequently, the first linear cylinder 328 of the second horizontal shifting mechanism 32 moves upward, driving the pressure block frame 326 and the pressure block 325 to move upward, no longer pressing the small box of label paper 8. After the left gripper 65 and the right gripper 66 clamp the small box of label paper 8, the second horizontal shifting mechanism 32 moves backward and pulls out the mounting plate 324. Then, the fifth linear cylinder 61 of the lowering mechanism 6 descends again, placing the small box label paper 8 onto the conveyor belt of the small box packaging machine. Subsequently, the sixth linear cylinder 64 operates, causing the left gripper 65 and the right gripper 66 to move away from the small box label paper 8, releasing the small box label paper. Finally, the fifth linear cylinder 61 retracts, returning to the stop position, completing the entire workflow.

[0056] It should be noted that, in specific implementations, the positions of each component of the present invention can be adjusted and modified according to the site conditions and design requirements. The present invention does not specifically limit the specific positions of each component.

The entire small box label unpacking and replenishing device is installed above the small box packaging machine, without occupying ground space or affecting the working positions of personnel and machinery. It is highly efficient and can replenish the consumption of the small box packaging machine at any time. The material of the small box label unpacking and replenishing device can be connected to the RGV trolley conveyor line and material station, realizing automatic buffering and automatic loading of materials from the warehouse to the packaging machine without human intervention, intelligent scheduling, and unmanned production. If the RGV trolley conveyor line is not used, an elevator can be installed for independent unit use. The number of conveying components can be adjusted according to the distance between the conveyor line and the feeding port of the small box packaging machine, or the buffer capacity, which is very convenient. It adopts a modular design, which is simple and convenient, and is suitable for small box label paper of different specifications. It features a bottom-level unpacking design, where materials are conveyed to the lower level to complete the work without occupying the buffer space of the high-altitude buffer conveyor mechanism. Multiple sets of materials can be unpacked and supplied to the packaging machine at any time without affecting the buffer cycle time. It is easy to maintain, and the unpacking action can be observed. At the end of the shift, manual unloading is also possible, allowing excess small box label paper to be sent down from the high-altitude buffer conveyor mechanism without unpacking, facilitating the recovery of excess materials. It boasts a high degree of automation, simple operation, reasonable layout, and high work efficiency. The large buffer capacity of small box label paper can replace the manual feeding process, greatly reducing labor intensity, improving production efficiency, saving labor costs, and enhancing the level of automation, meeting the requirements of modern lean management in the tobacco production industry.
