After the user turns on the machine, the PLC controls the push plate motor to return the push plate to the initial position to prevent the push plate from damaging the cutter disc during operation. At the same time, the feeding device starts;

[0015] Start the machine and press the origin return button. The PLC will control the servo motor to start and drive the cutter disc device to make circular motion. When the origin limit sensor in the cutter disc device is triggered, the PLC main controller gradually stops sending pulses, and the cutter disc device runs slowly until the sensor trigger disappears and gradually decelerates to a stop. The stop point is the origin, and then the cutter disc device rotates to the set No. 1 cutter disc compensation point position;

[0016] After the position of the No. 1 cutter head is determined, verify that the zero calibration is correct and use the automatic mode or inching control program on the touch screen to debug the equipment;

[0017] Press the automatic operation mode button, the feeding device will transport the long bamboo tube into the diameter measurement area, send the long bamboo tube to the top, and the gear lever will catch the long bamboo tube; when the bamboo tube is detected at the top, the feeding device will stop;

[0018] After the feeding device stops, the diameter is measured. After the measurement is completed, the bamboo is sent to the transfer position. When the bamboo drop conditions are met, the bamboo is dropped into the punching groove and the cutter disc motor is controlled to take the corresponding cutter disc; at the same time, the clamping arm of the clamping and centering device clamps the bamboo tube and aligns it with the center of the selected cutter disc;

[0019] After the cutter disc is selected, the impact disc motor is turned on; the bamboo breaking device moves forward, and when the bamboo breaking device moves forward to the No. 4 limit proximity switch, the clamping arm of the clamping and centering device releases the long bamboo tube, allowing the impact disc to continue to move forward until the bamboo tube is pushed to the bottom, and a bamboo tube is broken;

[0020] At this time, the bamboo breaking device turns around until it hits the No. 4 limit switch and the clamping device clamps it, and then when it reaches the No. 2 limit switch, another bamboo is sent and the bamboo tube is clamped again;

[0021] After the bamboo-breaking device continues to retreat and hits the initial limit switch No. 0, the bamboo-breaking device stops and completes a cycle. If the collision plate is not at the limit switch No. 0, the bamboo-breaking cycle is repeated, otherwise an alarm is sounded.

[0022] The control system and control method of an automated bamboo breaking production line of the present invention combine a control program and a sensor to design an automatic feeding chain transmission device to realize sequential conveying and continuous interval feeding of bamboo tubes of different shapes, lengths, bending degrees, and weights, thereby ensuring the reliability and stability of bamboo tube feeding and reducing manpower and labor intensity; a diameter measuring device and a data conversion device are designed to quickly, stably, and accurately measure the diameter of the bamboo tube in coordination with the diameter measuring program and the mechanical action of the feeding device, and the control system determines which cutter disc to switch to based on the information.

[0059] See also Figure 14-Figure 23 The present invention also provides a method for controlling an automated bamboo-breaking production line, which uses the automated bamboo-breaking production line control system described above and comprises the following steps:

[0060] S1: Place the long bamboo tube on the inclined frame of the automatic feeding device. After the user turns on the machine, the PLC controls the push plate motor to return the collision plate to the initial position to prevent the collision plate from damaging the knife disc during operation. At the same time, the feeding device starts;

When the start limit sensor in the cutter disc device is triggered, the PLC main controller gradually stops sending pulses. The cutter disc device runs slowly until the sensor trigger disappears and then stops immediately. The stop point is the origin. After that, the cutter disc device rotates to the set No. 1 cutter disc compensation point position (this position can be set manually for easy adjustment);

[0062] S3: After the position of the No. 1 cutter head is determined, verify that the zero calibration is correct and debug the equipment using the automatic mode or inching control program on the touch screen;

[0063] S4: Press the automatic operation mode button, the feeding device transports the long bamboo tube into the diameter measurement area, sends the long bamboo tube to the top, and the gear lever catches the long bamboo tube; when the bamboo tube is detected at the top, the feeding device stops;

[0064] S5: After the feeding device stops, the diameter is measured. After the measurement is completed, the bamboo is sent to the transfer position. When the bamboo drop conditions are met, the bamboo is dropped into the punching groove and the cutter disc motor is controlled to select the corresponding cutter disc; at the same time, the clamping arm of the clamping and centering device clamps the bamboo tube and aligns it with the center of the selected cutter disc;

[0065] S6: After the cutter disc is selected, the impact disc motor is turned on; the bamboo breaking device moves forward, and when the bamboo breaking device moves forward to the No. 4 limit proximity switch, the clamping arm of the clamping and centering device releases the long bamboo tube, allowing the impact disc to continue to move forward until the bamboo tube is pushed to the bottom, and one bamboo tube is broken;

[0066] S7: At this time, the bamboo breaking device returns until it hits the No. 4 limit switch and the clamping device clamps it, and then when it reaches the No. 2 limit switch, another bamboo is sent and the bamboo tube is clamped again;

[0067] S8: After the bamboo breaking device continues to retreat and hits the initial limit switch No. 1, the bamboo breaking device stops and completes a cycle. If the bamboo breaking device is not at the limit switch No. 0, the bamboo breaking cycle is repeated, otherwise an alarm is issued.

[0068] In this embodiment, the optimal synchronous control system includes five processes that are synchronously controlled and executed simultaneously (T1-T5). Step T1: Transfer bamboo to the buffer position, calculate the knife number and sorting position, and step A are performed synchronously (not necessarily starting or ending at the same time, there is a certain overlap area); Step T2: Drop bamboo to the slot and select the knife are performed synchronously; Step T3: The clamping device loosens the arm and the pressure wheel presses down synchronously; Step T4: The clamping device is centered and the pressure wheel rises synchronously (not necessarily starting or ending at the same time, there is a certain overlap area); Step T5: The data at T1 is synchronized during sorting here (data synchronization).

[0071] like Fig.23 , the timing control includes three major stages: sorting control, bamboo breaking control, and material collection control. The sorting control includes loading bamboo, measuring, and transferring; the bamboo breaking control includes selecting knives, dropping bamboo, and hitting bamboo; the material collection control includes receiving returned bamboo and sorting bamboo; the receiving returned bamboo includes pressing wheels, pushing bamboo out to the right, and pushing bamboo out to the top; the bamboo sorting includes clamping claws, sorting positioning, clamping claws releasing, and sorting resetting. Each round of bamboo breaking control starts when the upper wheel selects knives and ends when the lower wheel pushes bamboo out to the right. This round of diameter measurement is completed during the upper wheel dropping bamboo, hitting bamboo, and pressing wheel stages. This cycle achieves efficient and automatic bamboo breaking;

[0072] Aiming at the innovation of the fully automatic bamboo breaking and bamboo chip high-speed sorting production line, the technical scheme of automatic bamboo breaking machine mechanical systematization is adopted, and the automatic loading mechanism 1, automatic diameter measuring mechanism 2, automatic clamping and centering mechanism 3, automatic knife disc positioning mechanism 4, automatic bamboo breaking mechanism 5, automatic feeding mechanism 6, automatic sorting mechanism 7 and automatic bamboo breaking control system are designed.

[0073] The automatic feeding mechanism 1 realizes automatic loading of bamboos and transports the bamboos to the diameter measuring station one by one. After the diameter measurement is completed, it will be automatically clamped and aligned. The automatic knife disc positioning mechanism 4 selects different knives according to the diameter of the bamboo to automatically break the bamboo. The broken bamboo enters the feeding mechanism in the form of bamboo chips, and then passes through the corresponding station of the sorting mechanism transported by the guide rail, and enters the collection box 73 under the grasping of the material clamp 726, completing the entire bamboo breaking and sorting process.

[0074] It can complete the whole working process of the bamboo breaking production line, has reliable performance, high productivity and has practical promotion value.
