[0070] In step S20, position information collected by the control module is acquired, control instructions are generated in the control module according to the position information and the cutting information, and control object information corresponding to the control instructions is determined.

[0071] In the embodiment, after the cutting information is determined, the position information is collected in real time by the position sensor in the control module, which is arranged at a fixed position of each conveying belt, but the sensing position can be changed according to the user setting. Therefore, each conveying belt can be divided into a conveying area and a cutting area according to the sensing position of the position sensor, that is, the position point sensed by the position sensor. The cut material can be controlled to convey at the maximum conveying speed in the conveying area, and the cut material can be controlled to convey at the self-defined speed in the cutting area, so as to coordinate the control of conveying and cutting, and further improve the cutting efficiency of the whole cutting. It should be noted that the conveying speed is different from the cutting speed, which can neither waste time nor ensure the coordination of multiple cut materials in the cutting area, thereby improving the cutting efficiency. It should be further noted that when the position information of the cut material on the conveying belt is detected to match the preset position information (the preset position information refers to the cut material reaching the cutting point), the material of the cut material in the cutting information is determined, the best flying knife speed corresponding to the cutting material is determined, and the working instruction for controlling the flying knife to work is generated based on the best flying knife speed. By determining the control current corresponding to the best flying knife speed and the time from the cutting position of the material to the cutting point, the flying cutting module starts to work, and the best current increasing strategy is determined according to the control current and the time, which can realize steady current increase and avoid the phenomenon of instantaneous current increase damaging the motor. In addition, it can be ensured that the cut material starts to work only when it enters the cutting position, thereby improving the working accuracy and ensuring that the cutting knife does not rotate and heat up all the time.

[0072] After the position information is determined in the above manner, the control instruction for controlling the flying knife and the conveying belt is generated in the control module according to the position information and the cutting information. The step of generating the control instruction in the control module according to the position information and the cutting information includes:

[0073] Step C21, determining the material arrangement information in the cutting information by the control module, and determining the cutting requirement corresponding to the material arrangement information;

[0074] Step C22, detecting whether the position information matches the preset position information;

[0075] In the embodiment, the material arrangement information in the cutting information is determined by the control module, and the cutting requirement corresponding to the material arrangement information is determined. The material arrangement information refers to the arrangement information of the cut material in the conveying belt, and the cutting requirement refers to the cutting length requirement of the cut material. At the same time, whether the position information matches the preset position information is detected. When the position information does not match the preset position information, the position information is continuously judged.

[0076] Step C23, if the position information matches the preset position information, determining the cutting length corresponding to the cutting requirement, and taking the length of the cutting length and the preset conveyor length as the distance from the knife, wherein the preset conveyor length is the conveyor length of the cutting region;

[0077] Step C24, determining the distance from the knife of all the materials according to the material arrangement information, determining the actual conveying speed of each material according to the distance from the knife, and correcting the actual conveying speed according to the preset correction value and the material arrangement information to obtain the control instruction.

[0078] In the embodiment, when the position information matches the preset position information, the cutting length corresponding to the cutting requirement is determined, and the length of the cutting length and the preset conveyor length is taken as the distance from the knife. The cutting length refers to the length of the material from the cutting point to the cutting position, the conveyor length refers to the length from the cutting point to the cutting region, that is, the conveyor length of the cutting region, and the distance from the knife refers to the distance from the cutting point to the cutting position of the material to be cut. Refer to Figure 10 , Figure 10The fly cutting control method is shown in the figure. Taking two conveyors as an example, the to-be-cut materials 1 and 2 are transported on the corresponding conveyors 1 and 2, and the corresponding cutting lengths 1 and 2 are obtained. Assuming that the to-be-cut material 2 reaches the to-be-cut position 2 in the preset position information, the distance 2 from the to-be-cut material 2 to the cutter is obtained, and the sum of the cutting length 2 of the to-be-cut material 2 and the conveyor length between the to-be-cut point and the cutting point in the to-be-cut area is taken as the distance 2 from the to-be-cut material 2 to the cutter. When the to-be-cut material 1 reaches the to-be-cut position in the preset position information, the distance from the to-be-cut material 1 to the cutter is determined according to the above method. Then, the conveying speed of the to-be-cut material in the to-be-cut area is determined according to the distances 2 and 1, and the to-be-cut positions on the materials with different cutting lengths are simultaneously transported to the cutting point of the conveyor. After reaching the to-be-cut position, only the conveyor length can be used for working transmission, and the conveyors at other positions stop working, thereby achieving the purpose of controlling the speed. Finally, the distance from the cutter of each material is determined according to the material arrangement information, the actual conveying speed of each material is determined according to the distance from the cutter, and the control instruction is obtained by correcting the actual conveying speed according to the preset correction value and the material arrangement information. The actual conveying speed refers to the speed of the to-be-cut area conveyor controlled by each conveyor, and the correction value refers to the correction value of the actual speed of the conveyor. For example, taking two conveyors as an example, the first to-be-cut material is placed on the first conveyor, and the second to-be-cut material is placed on the second conveyor. When the cutting length of the first to-be-cut material is 2m, the cutting length of the second to-be-cut material is 1m, and the preset conveyor length is 2m, the distance from the cutter of the first to-be-cut material is determined to be 4m, and the distance from the cutter of the second to-be-cut material is determined to be 3m. The actual conveying speeds of the second to-be-cut material and the first to-be-cut material are determined because the first to-be-cut material and the second to-be-cut material are respectively on the first conveyor and the second conveyor, and the cutting lengths are different. If the actual conveying speeds of the two are the same, there will be a difference in the time from the to-be-cut position to the cutting point. At this time, the correction value between the first conveyor and the second conveyor is determined, and the actual conveying speed is corrected according to the correction value and the material arrangement information. In addition, the conveyors can be raised and lowered according to the user input conveyor lifting instruction, thereby realizing cutting of different thicknesses, and improving the accuracy and efficiency of cutting.

[0079] In step S30, control is performed according to the control instruction and the control object information.

[0080] In the embodiment, after the control instruction and the control object are determined, the control instruction is sent to the control object in the corresponding control object information, and the control object is controlled by executing the control instruction. The control flow can be that the control instruction is sent to the transmission controller 51, the speed of each conveying belt is controlled by the transmission controller 51, and then the to-be-cut material of each conveying belt is sent to the cutting position at the same time. The control instruction is also sent to the flying knife servo driver 41, the flying knife servo motor 42 is controlled by the flying knife servo driver 41 to rotate, the rotary cutter arm 71 is driven by the flying knife servo motor 42 to start working, and then it can be ensured that the speed of the rotary cutter arm 71 slowly increases to the cutting speed when the to-be-cut material reaches the cutting position and the cutting is completed at the cutting speed. For example, the control instruction is a flying knife starting instruction, the flying knife starting instruction is sent to the flying knife servo module 40, the flying knife in the flying cutting module 70 starts working under the control of the flying knife servo module 40, and when the control instruction is the speed control instruction of each conveying belt, the speed control instruction is sent to the transmission servo module 50, and each conveying belt in the transmission module works at the speed specified by the instruction under the control of the transmission servo module 50. The step after the control according to the control instruction and the control object information includes:

[0081] In step C31, the collected collection information is acquired, and it is detected whether the comparison information in the collection information is within a preset comparison range, wherein the comparison information refers to a comparison result of an actual motor speed and a theoretical motor speed.

[0082] In step C32, if the comparison information in the collection information is not within the preset comparison range, an alarm instruction is generated, and the control module is controlled to alarm according to the alarm instruction.

[0083] In the embodiment, when the fly cutter in the fly cutting module starts to work, the safety and accuracy of the fly cutter are detected, mainly to acquire the collected information, on one hand to detect whether the comparison information in the collected information is in the preset comparison range, when the comparison information in the collected information is not in the preset comparison range, an alarm instruction is generated, and the control module is controlled to alarm according to the alarm instruction. The collected information refers to the rotation speed information, current information and temperature information collected by the rotation speed sensor, current sensor and temperature sensor, the comparison information refers to the current comparison information between the rotation speed current information corresponding to the rotation speed information and the current information, the actual motor rotation speed refers to the rotation speed information collected by the rotation speed sensor 81, and the theoretical motor rotation speed refers to the rotation speed corresponding to the current information collected by the current sensor 82. The comparison result can be obtained by determining the rotation speed difference between the two or the current difference between the two, that is, the comparison result can be the comparison result of the actual current and the theoretical current, or the comparison result of the actual rotation speed and the theoretical rotation speed. The comparison range refers to the allowable range of the current difference between the two, the alarm instruction refers to the control instruction for controlling the whole system to alarm, which can be in the form of alarm lamp working and display screen displaying, etc., which can avoid the safety problems caused by improper installation of the fly cutter or loosening of the fixed position during use, and can remind the user to pay attention in time, thereby improving the safety.

[0084] Step C33, detecting whether the temperature information in the collected information is in the preset temperature range;

[0085] Step C34, if the temperature information in the collected information is not in the preset temperature range, a temperature control instruction is generated, and a cooling module is controlled to work according to the temperature control instruction, so as to realize cooling.

The temperature range refers to the range value of the temperature, which can be set according to the actual experiment, and the temperature control instruction refers to the instruction for controlling the temperature to work, that is, when the fly cutter is overheated, the cooling module 00 or other cooling medium can be used for cooling work, or the fly cutter can be slowed down for cooling work, and then the temperature control instruction controls the cooling module to work, so as to realize cooling.
