[0023] 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.

[0024] Specifically, in this embodiment, the tobacco block visual recognition system may at least include a slicer 1 and a slicer outlet belt conveyor 9, a visual recognition detection device 3 arranged at the slicer outlet, a position correction device (pneumatic control system, the pneumatic control system includes an upper cylinder 4, a left cylinder 5, a right cylinder 6, a left rear cylinder 7, and a right rear cylinder 8) arranged on the belt conveyor, and a control system for receiving, comparing and controlling the cylinder movements. In the process of tobacco leaf shredding, the slicer 1 is responsible for cutting the compressed tobacco pack into uniform small pieces (tobacco blocks 2). Ensure that the cut tobacco blocks have regular shapes and sizes. 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 working state. It includes detecting whether the tobacco blocks are skewed, stuck or stacked, and feeding back the information to the control system. The specific detection process is to detect the contour features of the tobacco blocks. The contour features of the tobacco blocks can be, for example: the distance between the current detected tobacco block and the downstream adjacent tobacco block; whether there is a phenomenon of two tobacco blocks stacking; the tobacco block is tilted to the left; the tobacco block is tilted to the right.

[0025] The control system compares the profile features of the smoke block with the preset standard profile features, and determines the deviation results according to the comparison results. In the deviation results, different cylinder adjustment schemes can be further determined according to the specific deviation types in the deviation results, and the deviation results are sent to the gas control system.

[0026] The gas 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: When it is determined that the distance between the 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 position of the cigarette block to the correct position; 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 is actuated to push the stacked cigarette blocks to be flat on the belt surface; 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 according to the corresponding situation to return the position of the cigarette block to the normal position.

[0027] In addition, the effect structure diagram of a cigarette block visual recognition system in this embodiment can be as follows: Figure 3 As shown, it includes 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, a belt conveyor 9, an electronic belt scale 10, and a rehumidifier 11. After the tobacco block is cut out by the slicer, it is continuously inspected by the visual recognition device. If there is an abnormal contour feature of the tobacco block, the control system controls the corresponding correction device to act according to the abnormal situation, so that the tobacco block is continuously and neatly measured by the belt conveyor and the electronic belt scale and then enters the rehumidifier to complete the rehumidification process.

[0028] 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: Step S302, when detecting that the slicer is in operation, collecting the contour features of the tobacco block through a visual recognition detection device, and transmitting the contour features of the tobacco block to a control system.

[0029] Specifically, when implementing the constant flow control of the tobacco block visual system, it can be but is not limited to being applied to the control terminal, and the control terminal can realize the continuous and neat stacking of tobacco blocks on the slicer outlet belt by controlling the slicing outlet equipment architecture. When processing the 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, and when it is detected that the slicer is in a running state, it indicates that the slicer has sliced ​​the tobacco package, and then the visual recognition detection device can be controlled to detect the cut tobacco blocks at the slicing outlet, according to whether the corresponding detected tobacco block contour features are normal. Among them, the slicer can also be in a standby state or a stopped state, and when the slicer is in a standby state or a stopped state, it indicates that the slicer has not yet sliced ​​the tobacco package, and then the working status of the slicer can continue to be obtained at a preset time interval.

[0030] Step S304: the control system compares the contour feature of the cigarette block with a preset standard contour feature, determines a deviation result according to the comparison result, and sends the deviation result to the gas control system.

[0031] Specifically, after the control system obtains the contour features of the cigarette block, it compares the contour features of the cigarette block with the preset standard contour of the cigarette block, and determines whether there is a deviation result based on the difference in the comparison result. If there is a deviation result, when obtaining the contour features of the cigarette block, the following features are mainly obtained but not limited to: the distance between the current detected cigarette block and the downstream adjacent cigarette block; whether there is a phenomenon of two cigarette blocks overlapping; the cigarette block leaning to the left; the cigarette block leaning to the right. When the position of the cigarette block deviates, the control system controls the air control system to process the deviated cigarette block according to different position deviations, so as to make the position of the cigarette block return to the correct position and the intervals between each cigarette block consistent, thereby ensuring the stability of the cigarette block flow on the belt conveyor.

[0032] Furthermore, whether 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 beyond the normal range, it is considered that there is a position deviation, and the position deviation includes: The distance between the current detected smoke block and the adjacent downstream smoke block is too large, greater than 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); Furthermore, the image of the tobacco block detected by the visual recognition detection device disposed at the exit of the slicer within a preset time period is obtained, and any tobacco block image is selected to identify the contour feature of the tobacco block, and compared with the preset standard contour feature. When the similarity threshold in the comparison result does not exceed the preset threshold, the deviation result of the tobacco block is determined. For example, when the similarity between the contour feature of the tobacco block in the tobacco block image and the preset standard contour feature does not exceed the preset threshold, it means that the tobacco block is not close to the standard contour, and thus there is a deviation, and the deviation result is determined. On the contrary, when the similarity between the contour feature of the tobacco block in the tobacco block image and the preset standard contour feature exceeds the preset threshold, it means that the tobacco block is close to the standard contour, and thus there is no deviation.

[0033] 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 return the smoke block to a normal state.

[0034] 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 deviation based on the standard contour comparison, it can determine different cylinder adjustment plans according to the specific deviation type in the deviation result, and then adjust the cylinder through the cylinder adjustment plan to correct the smoke block. The cylinders may include but are not limited to upper cylinders, side cylinders (left cylinders and right cylinders), and rear cylinders (left rear cylinders and right rear cylinders). When actually controlling the cylinders, the air control system can be, but is not limited to, conducting the cylinders 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: When it is determined that the distance between the 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 position of the cigarette block to the correct position; 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 is actuated to push the stacked cigarette blocks to be flat on the belt surface; 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 according to the corresponding situation to return the position of the cigarette block to the normal position.

[0035] The embodiment of the present invention provides a constant flow control method based on a tobacco block visual recognition system. When the slicer is detected to be in operation, the contour features of the tobacco block are collected through a visual recognition detection device, and the contour features of the tobacco block are transmitted to the control system; the control system compares the contour features of the tobacco block with the preset standard contour features, determines the deviation results according to the comparison results, and sends the deviation results to the air control system; the air control system determines the 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. In this way, the tobacco blocks on the outlet belt of the slicer can be stacked continuously and neatly, the flow on the electronic belt scale is stable without large fluctuations, metering errors are avoided, the water addition control of the rehumidification equipment is stable, the moisture content of the tobacco leaves is balanced, and the softening effect is better.
