[0002] In the cigarette manufacturing process, the design and functionality of the slicer are crucial to ensuring the efficiency and quality of subsequent processing steps. Slicers are key equipment used in the tobacco processing industry to cut tobacco bales into small pieces (or "blocks") of a specific thickness.

Unless the context clearly indicates otherwise, the definition of a term is consistent throughout the specification.

[0044] like Figure 1 As shown, an embodiment of the present invention provides a tobacco block visual recognition system, including: a slicer 1, a tobacco block 2, a visual recognition device 3, an upper cylinder 4, a left cylinder 5, a right cylinder 6, a left rear cylinder 7, a right rear cylinder 8, and a belt conveyor 9.

[0045] Specifically, in this embodiment, the tobacco block visual recognition system may include at least a slicer 1 and a slicer outlet belt conveyor 9, a visual recognition detection device 3 located at the slicer outlet, a position correction device (pneumatic control system, comprising an upper cylinder 4, a left cylinder 5, a right cylinder 6, a left rear cylinder 7, and a right rear cylinder 8) located on the belt conveyor, and a control system for receiving, comparing, and controlling the cylinder movements. During the tobacco leaf shredding process, the slicer 1 is responsible for cutting compressed tobacco bales into uniform small pieces (tobacco blocks 2), ensuring that the cut tobacco blocks have a regular shape and size. The visual recognition device 3 is installed after the slicer and is used to monitor the state of the tobacco blocks output from the slicer in real time when the slicer is in operation. This includes detecting whether the tobacco blocks are skewed, stuck, or stacked, and feeding this information back to the control system. The specific detection process involves detecting tobacco block contour features. Tobacco block contour features may include: the distance between the current tobacco block being tested and the adjacent downstream tobacco block; whether two tobacco blocks are stacked; and whether the tobacco block is tilted to the left or right.

[0046] The control system compares the smoke block profile with a preset standard profile and determines a deviation based on the comparison results. Based on the deviation type, different cylinder adjustment solutions can be determined and sent to the air control system.

[0047] The air control system is used to adjust the cylinders in different positions according to the cylinder adjustment plan and return the smoke block to the correct position. The specific steps of returning to the correct position may include but are not limited to:

[0048] When it is determined that the distance between a cigarette block and the adjacent cigarette block downstream is too large, the two cylinders installed on the belt conveyor at the rear of the current cigarette block and the two cylinders on the left and right sides of the current cigarette block are controlled to operate sequentially to return the cigarette block to the correct position;

[0049] When it is determined that the distance between a cigarette block and the adjacent cigarette block downstream is too small, that is, the two cigarette blocks are stacked, the cylinder installed above the downstream of the current cigarette block will be activated to push the stacked cigarette blocks flat on the belt surface;

[0050] When it is determined that the cigarette block is tilted to the left or right, the two cylinders on the left and right sides of the cigarette block are controlled to move accordingly to return the position of the cigarette block to the normal position.

[0051] In addition, the effect structure diagram of a cigarette block visual recognition system in this embodiment can be as follows: Figure 3As shown, the system comprises a slicer 1, tobacco blocks 2, a visual recognition device 3, an upper cylinder 4, a left cylinder 5, a right cylinder 6, a left rear cylinder 7, a right rear cylinder 8, a belt conveyor 9, an electronic belt scale 10, and a rehumidifier 11. After being cut by the slicer, tobacco blocks are continuously inspected by the visual recognition device. If tobacco blocks have abnormal contour features, the control system controls the operation of corresponding corrective devices based on the abnormalities. This ensures that tobacco blocks pass continuously and neatly through the belt conveyor and are weighed by the electronic belt scale before entering the rehumidifier, completing the rehumidification process.

[0052] like Figure 3 As shown, an embodiment of the present invention provides a constant flow control method based on a cigarette block visual recognition system, comprising:

[0053] Step S302: When the slicer is detected to be in operation, the contour features of the tobacco block are collected by a visual recognition detection device, and the contour features of the tobacco block are transmitted to a control system.

[0054] Specifically, when implementing constant flow control of the tobacco block visual system, it can be applied to, but is not limited to, a control terminal. The control terminal can control and process the slicing outlet equipment architecture to achieve continuous and neat stacking of tobacco blocks on the slicer outlet belt. When processing tobacco blocks at the slicer outlet, it can be, but is not limited to, obtaining the working status of the slicer at a preset time interval. When the slicer is detected to be in an operating state, it indicates that the slicer has sliced ​​the tobacco pack. Then, the visual recognition detection device can be controlled to detect the cut tobacco block at the slicing outlet to determine whether the corresponding detected tobacco block contour features are normal. The slicer can also be in a standby state or a stopped state. When the slicer is in a standby state or a stopped state, it indicates that the slicer has not yet sliced ​​the tobacco pack. Then, the working status of the slicer can continue to be obtained at preset time intervals.

[0055] In step S304, the control system compares the contour features of the cigarette block with preset standard contour features, determines a deviation result based on the comparison result, and sends the deviation result to the gas control system.

[0056] Specifically, after acquiring the tobacco block's profile features, the control system compares them with a preset standard profile. Based on the differences in the comparison results, it determines whether a deviation exists. If a deviation exists, the control system primarily acquires, but is not limited to, the following features: the distance between the current tobacco block being tested and the immediately downstream tobacco block; the presence of two overlapping tobacco blocks; the tobacco block leaning to the left; and the tobacco block leaning to the right. If a tobacco block's position deviates, the control system controls the pneumatic control system based on the position deviation to correct the position of the tobacco block and ensure consistent spacing between each tobacco block, thereby ensuring a stable tobacco flow on the belt conveyor.

[0057] Furthermore, the position of the tobacco block on the belt conveyor at the exit of the slicer is within the normal range of the tobacco block position on the belt surface. If it is outside the normal range, it is considered to have a position deviation. The position deviation includes:

[0058] The distance between the current detected smoke block and the adjacent downstream smoke block is too large, exceeding the preset distance upper limit (flow fluctuation); the distance between the current detected smoke block and the adjacent downstream smoke block is too small, less than the preset distance lower limit (two smoke blocks overlap); the smoke block tilts left or right (stuck or blocked during operation);

[0059] Furthermore, a visual recognition detection device located at the exit of the slicer obtains tobacco block images detected within a preset time period. Any tobacco block image is selected to identify tobacco block contour features and compare them with preset standard contour features. If a similarity threshold in the comparison result does not exceed a preset threshold, a deviation result for the tobacco block is determined. For example, if the similarity between the tobacco block contour features of the tobacco block image and the preset standard contour features does not exceed a preset threshold, it indicates that the tobacco block is not close to the standard contour, indicating a deviation, and a deviation result is determined. Conversely, if the similarity between the tobacco block contour features of the tobacco block image and the preset standard contour features exceeds a preset threshold, it indicates that the tobacco block is close to the standard contour, indicating no deviation.

[0060] In step S306 , the gas control system determines a cylinder adjustment plan based on the deviation result, and adjusts the cylinder according to the cylinder adjustment plan to restore the smoke block to normal.

[0061] Specifically, the visual recognition detection device detects that there is a deviation in the position of the smoke block. After the control system confirms the existence of the deviation based on the standard contour comparison, it can determine different cylinder adjustment plans according to the specific deviation type in the deviation result. Then, the cylinder is adjusted through the cylinder adjustment plan to return the smoke block to the right position. The cylinders may include but are not limited to the upper cylinder, side cylinders (left cylinder and right cylinder), and rear cylinders (left rear cylinder and right rear cylinder). When actually controlling the cylinder, the air control system can be, but is not limited to, conducting the cylinder through a two-position five-way solenoid reversing valve to complete the action, and also includes a compressed air control pipeline, including a filter pressure reducing valve, a solenoid reversing valve, a cylinder, an air storage tank, etc., for the action of each cylinder. Detailed adjustment plans include but are not limited to:

[0062] When it is determined that the distance between a cigarette block and the adjacent cigarette block downstream is too large, the two cylinders installed on the belt conveyor at the rear of the current cigarette block and the two cylinders on the left and right sides of the current cigarette block are controlled to operate sequentially to return the cigarette block to the correct position;

[0063] When it is determined that the distance between a cigarette block and the adjacent cigarette block downstream is too small, that is, the two cigarette blocks are stacked, the cylinder installed above the downstream of the current cigarette block will be activated to push the stacked cigarette blocks flat on the belt surface;

[0064] When it is determined that the cigarette block is tilted to the left or right, the two cylinders on the left and right sides of the cigarette block are controlled to move accordingly to return the position of the cigarette block to the normal position.

[0065] The embodiment of the present invention provides a constant flow control method based on a tobacco block visual recognition system. When the slicer is in operation, the visual recognition detection device collects the contour features of the tobacco block and transmits the contour features to the control system. The control system compares the contour features of the tobacco block with preset standard contour features, determines the deviation results based on the comparison results, and sends the deviation results to the air control system. The air control system determines a cylinder adjustment plan based on the deviation results, adjusts the cylinder according to the cylinder adjustment plan, and returns the tobacco block to the correct position. This can achieve continuous and neat stacking of tobacco blocks on the slicer outlet belt, stable flow without large fluctuations on the electronic belt scale, avoid measurement errors, stable water addition control of the rehumidification equipment, balanced moisture content of the tobacco leaves, and better re-softening effect.
