[0014] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Figure 1 This is a schematic diagram of a material conveying system provided in an embodiment of the present invention. The material conveying system provided in this embodiment of the present invention can be used in a tobacco production line. (See reference...) Figure 1The material conveying system provided in this embodiment of the utility model includes: a storage tank 1, a first conveying device 2, a lifting device 3, and a feeder 4 arranged in sequence; the storage tank 1 contains material, the first conveying device 2 is located at the outlet of the storage tank 1 and is used to convey the material to the lifting device 3, the lifting device 3 is located on the side of the first conveying device 2 away from the storage tank 1 and is used to convey the material to the feeder 4, the feeder 4 conveys the material to the rear feeding device 5; wherein, a first image acquisition device 6 is included in the direction of the lifting device 3 and / or above the feeder 4, the first image acquisition device 6 acquires material images at the lifting device 3 and / or the feeder 4.

[0017] like Figure 1 As shown, storage tank 1 is used to hold materials, which may be tobacco leaves. The material in storage tank 1 is conveyed to the first conveying device 2, which then conveys the material to the lifting device 3. The material is then supplied to the rear feeding device 5 via the first conveying device 2, the lifting device 3, and the feeder 4 for production. Storage tank 1, first conveying device 2, lifting device 3, and feeder 4 are sequentially arranged in the material conveying path of the material conveying system, forming a material conveying channel.

[0018] The structure of the lifting device 3 and the feeder 4 is not limited in this embodiment, and those skilled in the art can set them according to actual needs. For example, in some optional embodiments, the lifting device 3 may be a super elevator, but it is not limited thereto. (See reference...) Figure 1 The lifting device 3 may include a first track and a first material receiving frame. The first track extends upward, and material conveyed by the first conveying device 2 enters the first material receiving frame. The first material receiving frame can move on the first track, thereby conveying the material to the feeder 4. The feeder 4 may include a second track and a second material receiving frame. The second track extends upward, and material conveyed by the second conveying device enters the second material receiving frame. The second material receiving frame can move on the second track, thereby conveying the material to the rear feeding device 5.

[0019] Figure 1 In the illustrated embodiment, the installation heights of the storage tank 1, the lifting device 3, and the feeder 4 gradually increase, which is more suitable for situations where the height of the rear feeding device 5 is relatively high, for example... Figure 1 The conveying system shown spans at least two floors, with the storage tank 1, the first conveying device 2, and the lifting device 3 located on the lower floor, and the feeder 4 and the rear feeding device 5 located on the upper floor. Figure 1 The black arrow in the middle indicates the direction of material conveying.

[0020] This utility model embodiment proposes that a first image acquisition device 6 can be installed above the lifting device 3 and / or the feeder 4 to acquire images of the material at the lifting device 3 and / or the feeder 4, that is, the first image acquisition device 6 acquires material images during the conveying process.

[0021] By installing the first image acquisition device 6, the material image in the conveying channel can be detected, thereby determining the material conveying status based on the material image in the conveying channel, realizing real-time monitoring of the material conveying status, timely detection of material flow interruption, ensuring continuous material supply, and thus ensuring product quality and consistency.

[0022] Optional, Figure 2 This is a schematic diagram of the electrical control structure of a material conveying system provided in an embodiment of the present invention. (See attached diagram.) Figure 2 The material conveying system also includes a controller 7 and an alarm device 8. The controller 7 is electrically connected to the first image acquisition device 6 and the alarm device 8 respectively. The controller 7 determines whether the material is continuous based on the material image acquired by the first image acquisition device 6 and issues an alarm when the material flow is interrupted.

[0023] For example, the material conveying system may also include a controller 7, which is electrically connected to a first image acquisition device 6. The first image acquisition device 6 acquires material images during the conveying process and sends the material images to the controller 7. The controller 7 can pre-establish a training, testing, and verification dataset for a target recognition algorithm through big data analysis. A material conveying model is trained using this dataset. Based on the material conveying model and the material images acquired by the first image acquisition device 6, the continuity of the material is identified. Continuous material conveying indicates normal material transport; discontinuous material conveying indicates a material flow interruption. When a material flow interruption is detected, an alarm signal is sent to an alarm device 8. The alarm device 8 responds to the alarm signal and issues an alarm to alert personnel that a material flow interruption problem exists and requires timely handling.

[0024] The alarm device 8 may include a display screen and / or a speaker, and when it is determined that the material flow has been interrupted, the alarm may provide text and / or voice reminders.

[0025] In this embodiment of the present invention, a first image acquisition device 6 is added to the material conveying system. The first image acquisition device 6 acquires material images at the lifting device 3 and / or the feeder 4, which can determine the material conveying status and realize real-time monitoring of the material conveying status. This allows for timely detection and handling of flow interruptions, ensuring a continuous supply of materials and guaranteeing product quality and consistency.

[0026] Figure 1 In the embodiment shown, the first image acquisition device 6 includes a first high-speed camera 61 and a second high-speed camera 62; the first high-speed camera 61 is installed above the lifting device 3 and is used to acquire material images at the lifting device 3; the second high-speed camera 62 is installed above the feeder 4 and is used to acquire material images at the feeder 4.

[0027] like Figure 1As shown, the first image acquisition device 6 may include two high-speed cameras, namely a first high-speed camera 61 and a second high-speed camera 62. A high-speed camera is a photographic device specifically designed to capture high-speed motion. It has a high frame rate and shutter speed, enabling it to continuously capture images at extremely high speeds, thereby capturing details and moments in high-speed motion. In addition, high-speed cameras are typically equipped with high resolution and buffer storage to process and store large amounts of image data, ensuring that the captured motion images are clear and complete. Using a high-speed camera to acquire material images during the conveying process ensures the clarity of the material images.

[0028] refer to Figure 1 The first high-speed camera 61 and the second high-speed camera 62 are electrically connected to the controller 7. The first high-speed camera 61 is positioned above the lifting device 3 and can capture material images at the lifting device 3. The controller 7 identifies the continuity of material at the lifting device 3 based on the images captured by the first high-speed camera 61. The second high-speed camera 62 is positioned above the feeder 4 and can capture material images at the feeder 4. The controller 7 identifies the continuity of material at the feeder 4 based on the images captured by the second high-speed camera 62. In this way, a relatively comprehensive material image can be captured during the conveying process, thereby improving the comprehensiveness of the monitoring of material conveying.

[0029] Figure 3 This is a schematic diagram of another material conveying system provided in an embodiment of the present invention. (See reference...) Figure 3 In some other embodiments, the first image acquisition device 6 may include a high-speed camera mounted above the lifting device 3 and the feeder 4, which can simultaneously acquire material images at the lifting device 3 and the feeder 4, but is not limited to this.

[0030] Optionally, in some embodiments, the front end of the lifting device 3 may also include an electronic belt scale (not shown in the figure), which can detect the weight of the material. By combining the material image at the lifting device 3 and the data from the electronic belt scale, the accumulation of material at the lifting device 3 can be analyzed, thereby triggering an alarm when a blockage occurs.

[0031] Continue to refer to Figure 1 In some embodiments, the installation height of the lifting device 3 is higher than the installation height of the storage tank 1; the height of the first conveying device 2 near the lifting device 3 is higher than the height of the first conveying device 2 near the storage tank 1.

[0032] like Figure 1 As shown, the lifting device 3 is higher than the storage tank 1, and the first conveying device 2 has an upward conveying structure, which is exemplary. Figure 1In the illustrated embodiment, the first conveying device 2 includes a first conveying component extending vertically and a second conveying component extending horizontally. Both the first and second conveying components may include a conveyor belt. The first conveying component is located between the storage tank 1 and the second conveying component. Material from the outlet of the storage tank 1 is successively conveyed to the lifting device 3 via the first and second conveying components. By setting the first and second conveying components, different sections of the conveyor belt can be controlled in segments, achieving more precise material conveying and positioning; in addition, the flexibility of the layout of the first conveying device 2 can be improved.

[0033] In other embodiments of this utility model, the first conveying device 2 may include an upwardly extending ramp. The design of the ramp can save space and reduce the difficulty of building the first conveying device 2. This utility model embodiment will not describe it in detail.

[0034] Optional, you can continue to refer to Figure 1 The material conveying system also includes a second conveying device 9, which is located between the lifting device 3 and the feeder 4, and is used to convey the material at the lifting device 3 to the feeder 4.

[0035] In this embodiment, the lifting device 3 and the feeder 4 are spaced apart, and the second conveying device 9 is installed between the lifting device 3 and the feeder 4. The material conveyed by the lifting device 3 is conveyed to the feeder 4 via the second conveying device 9.

[0036] Among them, optional, such as Figure 1 As shown, the installation height of the feeder 4 can be higher than the installation height of the lifting device 3, and the side of the feeder 4 near the lifting device 3 is flush with the highest point of the lifting device 3; the second conveying device 9 includes a horizontal conveyor belt, which can horizontally convey materials to the feeder 4.

[0037] In some production lines, there is a certain distance between the lifting device 3 and the feeder 4. Using the second conveying device 9 is beneficial to improving the material conveying efficiency.

[0038] Optionally, in some embodiments, the material conveying system may further include a second image acquisition device (not shown in the figure), which is installed above the first conveying device 2 and / or the second conveying device 9, for acquiring material images at the first conveying device 2 and / or the second conveying device 9.

[0039] In this embodiment, the second image acquisition device may include two high-speed cameras, which are respectively positioned above the first conveying device 2 and the second conveying device 9, thereby acquiring images of the materials on the first conveying device 2 and the second conveying device 9. The second image acquisition device may be electrically connected to the controller 7, which may determine the material continuity of the first conveying device 2 and the second conveying device 9 based on the material images acquired by the second image acquisition device.

[0040] By setting up a first image acquisition device 6 and a second image acquisition device, the material conveying status of the entire material conveying system can be monitored.

[0041] Optional, you can continue to refer to Figure 1 and Figure 2 The storage tank 1 also includes a third image acquisition device 10, which acquires images of the materials inside the storage tank 1.

[0042] like Figure 1 and Figure 2 As shown, the third image acquisition device 10 is electrically connected to the controller 7. The third image acquisition device 10 can acquire images of the materials inside the storage tank 1 and send these images to the controller 7. Based on the images of the materials inside the storage tank 1, the controller 7 can determine the material accumulation status inside the storage tank 1.

[0043] For example, the controller 7 may store a pre-trained volume measurement model, which can be combined with the volume measurement model and the material image inside the storage tank 1 to determine the material volume, thereby determining the material accumulation status.

[0044] The number and installation location of the third image acquisition device 10 are not limited. Figure 1 The illustration only shows a third image acquisition device 10 at the outlet of the storage tank 1, but it is not limited to this in practice. It is sufficient to ensure that the field of view of the third image acquisition device 10 covers the materials on the left and right sides of the storage tank 1.

[0045] For example, in some embodiments, the third image acquisition device 10 includes a 3D depth camera, which is mounted on the top of the inner wall of the storage cabinet 1.

[0046] The material image inside storage tank 1 can be a depth image of the material inside storage tank 1, such as... Figure 1As shown, a 3D depth camera can be positioned near the outlet of storage tank 1. During material conveying, the 3D depth camera can acquire depth images of the materials in storage tank 1. The structure of the 3D depth camera is not limited, and those skilled in the art can configure it according to actual needs. For example, the 3D depth camera can utilize technologies such as structured light, time-of-flight, or binocular vision to project infrared light onto the target object, then measure and analyze the reflection time or angular differences of the infrared light to calculate three-dimensional data such as the distance and position of the object, thereby obtaining a depth image of the material.

[0047] Optional, you can continue to refer to Figure 1 The bottom of the storage tank 1 also includes a bottom belt (not shown in the figure) and an encoder 11 mounted on the bottom belt shaft. The bottom belt is used to convey materials to the first conveying device 2; the encoder 11 is used to measure the discharge pulse value of the storage tank 1.

[0048] The bottom belt is used to transport the material in the storage tank 1 through the outlet of the storage tank 1 to the first conveyor device 2. The speed of the bottom belt can be determined according to the discharge pulse value of the encoder 11. Figure 2 As shown, in this embodiment, the controller 7 can also be electrically connected to the encoder 11. The encoder 11 sends the measured discharge pulse value to the controller 7. The controller 7 can combine the material image inside the storage tank 1 and the discharge pulse value to determine the discharge flow rate of the material, thereby realizing the prediction and forecasting of the flow rate data.

[0049] For example, the controller 7 can determine the material volume based on the image acquired by the third image acquisition device 10, and then determine the material weight based on the material volume. Combined with the discharge pulse value of the encoder 11, the discharge flow rate of the material can be calculated.

[0050] Additionally, as shown in the figure, the controller 7 can also be electrically connected to the bottom belt motor (not shown). The controller 7 can adjust the conveying speed of the bottom belt based on the discharge flow rate. For example, when the discharge flow rate inside the storage tank 1 increases, the conveying speed of the bottom belt can be reduced (e.g., the speed of the bottom belt motor can be reduced); when the discharge flow rate inside the storage tank 1 decreases, the conveying speed of the bottom belt can be increased (e.g., the speed of the bottom belt motor can be increased). In this way, the discharge flow rate of the storage tank 1 can be adjusted according to the actual situation of the material inside the storage tank 1 to ensure a continuous and stable material supply and improve production efficiency.

[0051] In this embodiment of the invention, a visual monitoring system can be formed by using the first image acquisition device 6, the second image acquisition device (not shown in the figure), and the third image acquisition device 10 to monitor the material conveying situation and ensure a continuous supply of materials.

[0052] Based on the same concept, this utility model embodiment also provides a tobacco production line, including the material conveying system provided in any embodiment of this utility model, possessing all the technical features and corresponding beneficial effects of the material conveying system provided in this utility model embodiment, which will not be repeated here.

[0053] For example, the tobacco production line may also include a back-end feeding device located at the rear end of the material conveying system, whereby the feeder in the material conveying system provides materials to the back-end feeding device. The back-end feeding device includes, but is not limited to, a metering tube, and this embodiment of the present invention does not limit this aspect.

[0054] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
