Technical Field

[0001] The invention relates to press feeding equipment, in particular to an intelligent control method for multiple mixing cloth vehicles for circular feeding of a press. Background Art

[0002] There are two types of traditional mixing and distributing equipment, linear and circular. The linear mixing and distributing equipment cannot realize cyclic loading, and although the circular mixing and distributing equipment can realize cyclic loading, it only has one mixing and distributing vehicle, which is inefficient. Both of the above two types of mixing and distributing equipment require manual operation, which has high labor costs and is prone to misoperation, thus causing equipment problems. Summary of the invention

[0005] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: Realize unmanned and intelligent control, and allow multiple mixing carts to operate in a continuous cycle, thereby improving the rhythm of the entire production line, increasing the capacity of the entire production line, and thereby increasing production efficiency and saving costs.

[0009] After the press mold completes pressing and returns to the receiving position, the unloading counter is reset to 0, and the last mixing car runs to the unloading position to unload.

[0010] After the material tank is covered, the material tank driving mechanism drives the material tank to rotate.

[0011] The host computer calculates the speed of the travel motor according to the mixing time, and triggers the push-in calculation of the first-in-first-out algorithm when reaching the unloading waiting position.

[0012] The material tank position sensor detects the position of the material tank in real time.

Install the annular rack 1, a plurality of legs 101 are installed at the bottom of the annular rack 1, an annular guide rail 2 is installed on the annular rack 1, an annular busbar 3 is installed on the inner side of the annular guide rail 2, and a main control box 4 is installed on the legs 101.

[0019] S2, placing the first mixing cloth trolley 5, the second mixing cloth trolley 6, the third mixing cloth trolley 7 and the fourth mixing cloth trolley 8 on the circular guide rail 2. Each mixing cloth trolley includes a frame 501, a drive shaft, a drive wheel 502, a travel drive mechanism 503, a bracket 504, a material tank 505 and a material tank drive mechanism 506. Wheel axles are rotatably mounted at both ends of the frame 501, and the drive wheels 502 are mounted at both ends of the wheel axle. The wheel axle is driven by a travel drive mechanism 503 mounted on the frame 501. The travel drive mechanism 503 is a reduction motor, and the travel motor of the travel drive mechanism 503 is a variable frequency motor. The travel drive mechanism 503 is equipped with a travel encoder 507; Horizontal ear shafts are symmetrically installed on both sides of the middle of the material tank 505. The ear shafts are rotatably connected to the bracket 504 through a bearing seat. The ear shaft on one side is installed with a material tank position sensor 508. The ear shaft on the other side is connected to the output shaft of the material tank driving mechanism 506 through a coupling. The material tank driving mechanism 506 is composed of a motor and a reducer. The motor is a variable frequency motor. The material tank driving mechanism 506 drives the material tank 505 to rotate and mix materials; The equipment is powered on and put into trial operation to check the operating status. The four mixing carts are manually operated to verify whether the travel motor, travel encoder 507, and tank position sensor 508 are operating correctly. Each action of the equipment is manually operated to check whether the action is correct.

[0020] S3, the ring frame 1 is provided with a loading position, a lid closing position, a stirring area, a loading waiting position, a discharging position and three discharging waiting positions ( Figure 3 As shown in the figure), the loading position is equipped with a proximity switch. When each mixing material vehicle runs to the loading waiting position, the manual initialization button is triggered to automatically initialize the equipment operation angle, tank body, tank cover and other states.

[0021] S4. The host computer sets the loading position to 0 degrees, the cover position to 30 degrees, the third waiting position to 180 degrees, the second waiting position to 210 degrees, the first waiting position to 240 degrees, the unloading position to 270 degrees, the loading waiting position to 330 degrees, and the mixing area between the cover position and the first waiting position. The host computer calculates the speed of the travel motor of the mixing material car according to various angles. During the operation of the mixing material car, the travel encoder 507 calculates the angle and speed of the mixing material car in real time. The material tank position sensor 508 detects the position of the material tank 505, calculates the speed of the travel motor according to the set mixing time, and triggers the push calculation of the first-in-first-out algorithm when it reaches the unloading waiting position.

[0022] S5 , initialization, the first fabric mixing cart 5 is located at the 270 degree position, and the second fabric mixing cart 6 , the third fabric mixing cart 7 and the fourth fabric mixing cart 8 are placed behind the first fabric mixing cart 5 in sequence.

[0023] S6, automatic start, the first mixing cart 5 automatically moves to the 0 degree position, and the proximity switch is triggered, automatically setting the position of the first mixing cart 5 to 0 degrees, and the first mixing cart 5 is loaded. The second mixing cart 6 detects that the distance between it and the first mixing cart 5 is greater than 30 degrees, and automatically moves forward. When the angle difference between the second mixing cart 6 and the first mixing cart 5 is 35 degrees, it slows down and stops at 30 degrees. The third mixing cart 7 and the fourth mixing cart 8 run in sequence.

[0024] S7, after loading, the first mixing and fabricating vehicle 5 moves to the covering position at 30 degrees to cover.

[0025] S8. After closing the cover, the first mixing vehicle 5 moves forward and counts time. The tank driving mechanism 506 drives the tank 505 to rotate for mixing. When the tank reaches the 270° position, the mixing is completed. The mixing time is 120 seconds.

[0026] S9, the first mixing cloth vehicle 5 moves forward to the first unloading waiting position, the travel motor stops, and the material tank driving mechanism 506 drives the material tank 505 to a vertical state, ready to enter the unloading position for unloading. The first mixing cloth vehicle 5 continues to move forward to the unloading position at the 270-degree position for unloading, and the tank cover is opened for unloading. After the first mixing cloth vehicle 5 unloads, the unloading counter of the host computer is increased by 1.

[0027] S10, the second mixing cloth trolley 6 and the third mixing cloth trolley 7 repeat steps S6-S9 in sequence to load and unload. When the value of the unloading counter of the host computer is 3, a feeding completion signal is sent to the press. The fourth mixing cloth trolley 8 is located at the first unloading waiting position and waits.

[0028] S11, the press mold completes pressing and returns to the receiving position, and the unloading counter is reset to 0. After the fourth mixing material vehicle 8 receives a signal that the value of the unloading counter is less than 3, the fourth mixing material vehicle 8 runs to the unloading position to complete unloading, and then runs to the loading position to load.

[0029] S12: All the mixed material vehicles complete one feeding cycle.
