Specifically, the control mechanism 8 includes a timer 81, a reader/writer 82, a data processing unit 83 and a control unit 84, the control unit 84 starts the timer 81 to count after receiving the first identification signal output by the defect identifying mechanism 3, the speed feedback information of the encoder is transmitted to the data processing unit 83, the reader/writer 82 reads the real-time count time node value of the timer 81 once in real time every time the control unit 84 receives the identification signal, the data processing unit 83 calculates the distance between adjacent spraying marks according to the difference value of the adjacent time nodes and the speed feedback information, the control unit 84 judges the cutting position of the cutter mechanism 5 according to the comparison result of the distance value between the adjacent spraying marks and a normal plate length, and the flow chart of the control mechanism detecting and judging the cutting position of the cutter according to the mark spacing is shown in fig. 3.
In the prior art, a plate cutting machine cuts a plate at intervals according to a plate conveying speed, a worker checks a defective plate and separates a waste plate (defective plate) from a conveying belt, namely, the waste plate is discharged, but because the formed plate is usually longer, the formed plate is detected after linear cutting, a large section of good plate is easily cut off as the waste plate to cause waste.
For example, when two plates are broken at a plurality of positions in length and the distance between two adjacent broken positions is smaller than the length of two plates but not smaller than the length of one conventional plate, if the conventional dividing mode is adopted, the two plates are waste plates, but if the distance between the two broken positions is detected, a qualified plate can be obtained from the plates with the two plate lengths, and waste is not easy to cause. Therefore, the essence of this embodiment is to identify defects and determine the distance between adjacent defects, determine the specific cutting position according to the distance between defects, ensure that the waste board is completely cut and discarded, and minimize the length of the good board in the waste board, so that the good board can be left as much as possible.
Therefore, in this embodiment, the long distance of two plates is used as a detection interval, the speed of the transmission belt is measured, the time difference between two adjacent marks is detected, the interval distance is obtained, if the two distances are smaller than the length of one plate, the tail of the mark adjacent to one good plate is cut, a waste plate is formed, and if the distance between the two marks is detected to be larger than the length of one plate, normal cutting is performed, and the good plate is obtained.

Identifying defects occurring on the marked sheet material in two sheet length areas and judging the cutter position according to the distance between adjacent defects, namely, in the two sheet length areas, if the distance between the adjacent defects is larger than one sheet length, the two defects are a complete good sheet material, cutting out the two sheet materials at intervals is needed, the sheet materials on two sides of the two defects in the area are waste sheet materials which need to be cut out, wherein the part, which is close to the outer side of the defect mark on one side of the cutter mechanism 5, is needed to be cut off and put waste, and is cut near the mark (cutting position); the defect mark outside near the upstream side needs to be combined with the defect recognition condition of the next two plates in the length range to judge the subsequent cutting position.
In detail, the control mechanism 8 further comprises a first timer 85 and a second timer 86, wherein the first timer 85 is used for buffering and conveying the plate area with the spraying mark, and the timing time of the second timer 86 is a normal plate length conveying time.
