[0011] Preferably, the manual grading area includes a manual grading device, a second conveyor belt, and a tobacco leaf turning device;

[0012] The second conveyor belt is connected at its starting end to the stepping buffer area and at its end to the tobacco leaf turning device. The tobacco leaf turning device is connected to the weighing area. The second conveyor belt is used to transport tobacco bales and tobacco leaves, and the tobacco leaf turning device is used to change the transport direction of the tobacco leaves.

[0013] The manual grading device is located on the side of the second conveyor belt. The manual grading device is used to remove the wrapper of the tobacco pack and grade the tobacco leaves inside.

[0014] Preferably, the weighing area includes an automatic weighing device and a third conveyor belt. The automatic weighing device is connected to the manual grading area, and the starting end of the third conveyor belt is connected to the automatic weighing device, while the ending end is connected to the sorting area.

[0015] The automatic weighing device is equipped with a first reader, which is used to read the tobacco leaf grade. The automatic weighing device is used to weigh the tobacco leaf and record the tobacco leaf grade and weight.

[0016] Preferably, the sorting area includes multiple fourth conveyor belts and multiple smoke cages, the multiple fourth conveyor belts are connected in sequence, and a smoke cage is provided between every two fourth conveyor belts. The multiple smoke cages are used to place tobacco leaves of different grades.

[0017] The higher end of the fourth conveyor belt is connected to the lower end of the next fourth conveyor belt and is located above the lower end of the next fourth conveyor belt. The fourth conveyor belt can rotate in both directions. When the fourth conveyor belt rotates in the forward direction, the tobacco leaves on it are transported to the next fourth conveyor belt.

[0025] Based on this, the beneficial effects of this utility model are as follows:

[0026] 1. The present invention employs automation in multiple areas, which not only reduces labor input but also greatly improves the efficiency of the entire storage system. Automatic grabbing robots replace manual warehousing operations at the entry point, freeing up labor and providing a safer warehousing operation mode. The stepping conveyor belt in the stepping buffer area not only provides the conveying function of a traditional conveyor belt but also buffers the incoming cigarette packs, balancing some of the speed mismatch issues caused by excessively fast warehousing and long grading times.

[0027] 2. The automatic sorting in the sorting area of ​​this utility model relies on mechanical automation. Most traditional sorting mechanisms are planar sorting devices. When an inclined conveyor is used for sorting, the density of the sorting mechanism can be increased. Under the same grading requirements, less floor space can be used. The addition of automation can also reduce the input of manual labor and improve the efficiency and accuracy of sorting. The forward and reverse rotation of the inclined conveyor is used to grade different tobacco leaves. When the inclined conveyor reverses, the tobacco leaves fall into the cage of the current grade. When the inclined conveyor rotates forward, the tobacco leaves can enter the next level conveyor with the conveyor. Then, the same judgment is performed at the next level to complete the grading of different tobacco leaves. Attached Figure Description

[0036] Figure 1This schematic diagram illustrates the structure of an automatic tobacco leaf conveying and grading device according to one embodiment of the present invention, as shown below. Figure 1 As shown, the present invention provides an automatic tobacco leaf conveying and grading device, comprising:

[0037] The following areas are arranged sequentially along the conveying direction: a cigarette pack temporary storage area 10, a stepping buffer area 20, a manual grading area 30, a weighing area 40, a sorting area 50, an operation area 60, and a storage area 70.

[0038] The stepping buffer area 20, manual grading area 30, weighing area 40 and sorting area 50 are connected by a conveyor belt. The sorting area 50 is connected to the operation area 60 and the operation area 60 is connected to the storage area 70 by a forklift 602.

[0039] The tobacco bale temporary storage area 10 is located on the side of the stepping buffer area 20 and close to the starting end of the stepping buffer area 20. The stepping buffer area 20 is used to transport tobacco bales. The tobacco bale temporary storage area 10 is used to temporarily store excess tobacco bales. The manual grading area 30 is used to grade the tobacco leaves in the tobacco bales. The weighing area 40 is used to weigh the tobacco leaves. The sorting area 50 is used to grade and pack the tobacco leaves into cages. The operation area 60 is used to compact the tobacco cages containing tobacco leaves. The storage area 70 is used to store the compacted tobacco cages.

[0040] With this setup, the present invention employs automation solutions in multiple areas, which not only reduces labor input but also greatly improves the efficiency of the entire storage system. At the same time, it relies on advanced industrial methods to improve the efficiency and accuracy of tobacco leaf grading and storage, thus completing the upgrade and transformation of the traditional tobacco leaf storage system.

[0041] Furthermore, the step buffer area 20 includes an automatic gripping robot 201 and a first conveyor belt 202. The automatic gripping robot 201 is located between the truck and the starting end of the first conveyor belt 202. The automatic gripping robot 201 is used to flip the cigarette packs in the truck onto the first conveyor belt 202. The first conveyor belt 202 is used to transport the cigarette packs on it to the manual grading area 30 at the end.

[0042] The cigarette pack storage area 10 is located on the side wall of the first conveyor belt 202 and close to the starting end of the first conveyor belt 202. When there are too many cigarette packs on the first conveyor belt 202, the cigarette pack storage area 10 is used to store the cigarette packs that the automatic grabbing robot takes out from the truck.

[0043] Specifically, the automatic gripping robot 201 is an automated gripping and transfer device. It utilizes an automatic gripping program in conjunction with human intervention. By pre-programming, it can call the pre-programmed program to complete the gripping of goods when a picking task is needed. Considering that cigarette packs are fixed goods of different standards, the gripping of cigarette packs can also be completed by on-site workers. For placing cigarette packs, the pre-programmed program can be directly called to complete the placement process. The whole process transfers the cigarette packs on the truck to the first conveyor belt 202 at the rear, completing the warehousing operation of the cigarette packs.

[0044] The first conveyor belt 202 is driven by a stepper motor and is a stepper conveyor belt. It can precisely control the position of materials and provide a buffer area to buffer cigarette packs when there are too many cigarette packs, such as a circulating conveyor belt, to prevent the accumulation of goods caused by the automatic gripping robot 201 working too fast. When the manual grading area 30 is completed, it can provide new cigarette packs in time. The use of the first conveyor belt 202 can improve the efficiency of cigarette pack transportation and solve the problem of mismatch between the speed of cigarette packs entering the system.

[0045] Because the unloading of cigarette packs is very fast, far exceeding the manual grading speed of the subsequent manual grading area 30, without a buffer area, the unloading speed of cigarette packs can only be slowed down. However, after the truck finishes unloading one load of goods, it will take a long time to complete the transfer of the next load of goods. Therefore, it is very necessary to set up a buffer area in the first conveyor belt 202 and a cigarette pack temporary storage area 10 on the side of the first conveyor belt 202 to better complete the loading and unloading process of materials.

[0046] Furthermore, the manual grading area 30 includes a manual grading device 301, a second conveyor belt 302, and a tobacco leaf turning device 303;

[0047] The second conveyor belt 302 is connected at its starting end to the stepping buffer area 20 and at its end to the tobacco leaf turning device 303. The tobacco leaf turning device 303 is connected to the weighing area 40. The second conveyor belt 302 is used to transport tobacco bales and tobacco leaves, and the tobacco leaf turning device 303 is used to change the transport direction of the tobacco leaves.

[0048] The manual grading device 301 is installed on the side wall of the second conveyor belt 302. The manual grading device 301 is used to remove the wrapper of the tobacco bale and grade the tobacco leaves inside.

[0049] Specifically, a worker is stationed at the manual grading device 301. This worker can manually receive tobacco bales, remove the bales wrappers, and grade the tobacco leaves inside to facilitate subsequent tobacco leaf storage. Before grading is completed, the tobacco bales will remain on the grading platform between the step buffer area 20 and the manual grading area 30, waiting for manual grading. After grading is completed, the worker uses a handheld RFID reader to write the tobacco leaf registration into the RFID tag, and at the same time pulls out the bales wrappers, controlling the tobacco leaves to be sent along the second conveyor belt 302 into the next process to complete the tobacco leaf grading.

[0050] When the second conveyor belt 302 transports tobacco leaves, the tobacco leaf turning device 303 changes the direction of tobacco leaf transport to avoid the conveyor belt being too long, thereby improving the overall space utilization efficiency.

[0051] Furthermore, the weighing area 40 includes an automatic weighing device 401 and a third conveyor belt 402. The automatic weighing device 401 is connected to the manual grading area 30, and the starting end of the third conveyor belt 402 is connected to the automatic weighing device 401, while the ending end is connected to the sorting area 50.

[0052] The automatic weighing device 401 is equipped with a first reader (not shown in the figure). The first reader is used to read the tobacco grade, and the automatic weighing device 401 is used to weigh the tobacco and record the tobacco grade and weight.

[0053] Specifically, the automatic weighing device 401 is an intelligent weighing device that can provide automatic weighing and recording. It has a first reader that can read the tobacco leaf grade by reading RFID, upload the tobacco leaf grade and the weighing weight to the central system to complete automatic weighing and recording, and can also display the weighed tobacco leaf weight so that workers can check whether it is normal.

[0054] Meanwhile, the third conveyor belt 402 is tilted to lift the tobacco leaves. Its lower end is connected to the automatic weighing device 401, and its higher end is connected to the sorting area 50. The height difference between its two ends can lift the tobacco leaves to a suitable height for the subsequent process, making it convenient for subsequent processes to operate.

[0055] Furthermore, the sorting area 50 includes multiple fourth conveyor belts 501 and multiple smoke cages (not shown in the figure). The multiple fourth conveyor belts 501 are connected in sequence, and a smoke cage is set between every two fourth conveyor belts 501. The multiple smoke cages are used to place tobacco leaves of different grades.

[0056] The higher end of the fourth conveyor belt 501 is connected to the lower end of the next fourth conveyor belt 501 and is located above the lower end of the next fourth conveyor belt 501. The fourth conveyor belt 501 can rotate in both directions. When the fourth conveyor belt 501 rotates in the forward direction, the tobacco leaves on it are transported to the next fourth conveyor belt 501. When the fourth conveyor belt 501 rotates in the reverse direction, the tobacco leaves on it are transported to the tobacco cage.

[0057] Specifically, a second reader (not shown in the figure) is also provided on the fourth conveyor belt 501. The fourth conveyor belt 501 is inclined, with an inclination angle ranging from 20 to 40°, preferably 30°. The lower end of the first fourth conveyor belt 501 is connected to the third conveyor belt 402, and the higher end is connected to the lower end of the second fourth conveyor belt 501, located above and extending 0.3m into it, so that the two fourth conveyor belts 501 partially overlap.

[0058] With this setup, during sorting, the second reader on the first fourth conveyor belt 501 detects the grade of the tobacco leaves. If the grade does not meet the requirements of the fourth conveyor belt 501, the fourth conveyor belt 501 rotates forward, and the tobacco leaves continue to be transported, falling from the high point of the first fourth conveyor belt 501 to the low point of the second fourth conveyor belt 501, where they are detected by the second reader on the second fourth conveyor belt 501. When the grade meets the requirements, the fourth conveyor belt 501 is reversed, causing the tobacco leaves to move towards the first fourth conveyor belt 501, into the space between the first and second fourth conveyor belts 501, and continue to fall into the tobacco cage between them, completing the tobacco leaf sorting. By overlapping the two conveyor belts, it is possible to prevent the tobacco leaves from falling directly into the tobacco cage when they fall from the first fourth conveyor belt 501, which would affect the tobacco leaf grading operation.

[0059] Meanwhile, the third conveyor belt 402 is also inclined, and a smoke cage is set between the third conveyor belt 402 and the first conveyor belt 501, which can also cooperate with the first fourth conveyor belt 501 to complete the sorting of tobacco leaves by grade.

[0060] By tilting the fourth conveyor belt 501 and setting it to rotate in both directions, different tobacco leaves can be graded. When the fourth conveyor belt 501 rotates in reverse, the tobacco leaves fall into the tobacco cage of this level. When the fourth conveyor belt 501 rotates in the forward direction, the tobacco leaves can enter the next level, and the same judgment is performed in the next level to complete the grading of the tobacco leaves. At the same time, the tilting setting of the fourth conveyor belt 501 can significantly reduce the space occupied by the sorting area 50, make reasonable use of the overall layout, and improve the space utilization rate.

[0061] Furthermore, the operating area 60 includes a smoke cage compactor 601 and a forklift 602. The forklift 602 travels between the sorting area 50 and the operating area 60, as well as between the operating area 60 and the storage area 70. The forklift 602 is used to move the smoke cages, and the smoke cage compactor 601 is used to compact the smoke cages.

[0062] Specifically, when the forklift 602 is working, it can transport the boxed tobacco leaves in the sorting area 50 from the boxing area to the designated position in the operation area 60, waiting for the tobacco cage compactor 601 to perform the pressing operation. After the pressing is completed, if the box is not full, the forklift 602 will quickly transport the box back to the corresponding position in the sorting area 50 to wait for the newly dropped tobacco leaves. If the box is full, the forklift 602 will pick up the full box of tobacco leaves and transport it to the storage area 70 for subsequent storage.

[0063] Furthermore, multiple storage areas 70 are provided, and these multiple storage areas 70 are divided into different levels of sections. Forklift 602 is used to store tobacco cages containing tobacco leaves in the corresponding level of storage area 70, thereby realizing tobacco leaf storage.

[0064] Furthermore, an empty box area 80 is also provided on the side of the sorting area 50. The empty box area 80 and the operation area 60 are located on the two sides of the sorting area 50, respectively. The empty box area 80 is used to replenish the empty tobacco cages to the sorting area 50 by forklift 602, so as to ensure that the tobacco leaves in the sorting area 50 can fall smoothly into the tobacco cages when they are graded.

[0065] In summary, the purpose of this utility model is to utilize automation in tobacco leaf conveying and grading devices to reduce labor input and improve the efficiency and accuracy of tobacco leaf grading and storage through advanced industrial methods, thereby upgrading and transforming the traditional tobacco leaf storage system.

[0066] The above description is merely a preferred embodiment of this application. Those skilled in the art should understand that the scope of disclosure in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
