Description

Technical Field

[0001] This invention relates to press feeding equipment, and more particularly to an intelligent control method for multiple mixing fabric carts using a ring-shaped feeding system for presses. Background Technology

[0002] Traditional mixing and distributing equipment comes in two types: linear and circular. Linear mixing and distributing equipment cannot achieve cyclic feeding, while circular equipment, although capable of cyclic feeding, only has one mixing and distributing trolley, resulting in low efficiency. Both types of equipment require manual operation, leading to high labor costs and a high risk of operational errors that can cause equipment malfunctions. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned technical problems, thereby providing an intelligent control method for multiple mixing fabric carts with circular feeding mechanism for presses, thereby improving production efficiency.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows:

[0005] A method for intelligent control of multiple fabric mixing trolleys using a ring-feed press includes the following steps:

[0006] S1. Install the ring frame, and install the ring guide rail, ring sliding contact line and main control box on the ring frame;

[0007] S2. Place multiple fabric mixing carts on a circular guide rail. The fabric mixing carts are equipped with a travel encoder and a material tank position sensor.

[0008] S3. The ring frame is equipped with a loading position, a cover closing position, a mixing area, a loading waiting position, a discharging position, and multiple discharging waiting positions.

[0009] S4. The host computer sets the loading position to 0 degrees, the lid-closing position to 30 degrees, the first waiting position to 240 degrees and the angle between adjacent waiting positions to 30 degrees, the unloading position to 270 degrees, the loading waiting position to 330 degrees, and the mixing zone between the lid-closing position and the first waiting position. The speed of the mixing and spreading vehicle is calculated based on each angle.

[0010] S5. Initialization: The first mixed fabric cart is positioned at 270 degrees, and the other mixed fabric carts are placed sequentially after the first mixed fabric cart.

[0011] S6. The first mixed fabric cart automatically moves to the 0-degree position and loads materials into the first mixed fabric cart;

[0012] S7. After the first mixed fabric cart is loaded, it moves to a 30-degree position and the cover is closed.

[0013] S8. The first mixing carriage moves forward and starts mixing the material. When it reaches the 240° position, the mixing is complete.

[0014] S9. The first mixed fabric car moves forward to the 270-degree position to unload the material;

[0015] S10. Except for the last mixed fabric car, the other mixed fabric cars repeat steps S6-S9 in sequence to load and unload materials.

[0016] S11, the press mold completes pressing and returns to the receiving position, and the last mixing material cart completes unloading and runs to the loading position for loading.

[0017] S12. All mixed fabric carts complete one feeding cycle.

[0018] Compared with the prior art, the present invention, which adopts the above technical solution, has the following beneficial effects:

[0019] By achieving unmanned and intelligent control, multiple fabric mixing vehicles operate continuously in a cycle, improving the cycle time and capacity of the entire production line, thereby increasing production efficiency and saving costs.

[0020] Furthermore, the optimized solution of the present invention is:

[0021] A proximity switch is installed at the loading position of the annular frame.

[0022] The mixing material cart includes a frame, a drive shaft, drive wheels, a walking drive mechanism, a support, a material tank, and a material tank drive mechanism. The drive wheels are rotatably mounted on the bottom of the frame via the drive shaft, which is driven by the walking drive mechanism, which is equipped with a walking encoder. Trunnions are installed on both sides of the material tank and are rotatably connected to the support. A position sensor is installed on one trunnion of the material tank, and the trunnion on one side of the material tank is driven and connected to the material tank drive mechanism.

[0023] After the first mixing fabric cart unloads material, the unloading counter of the host computer is incremented by 1. When the value of the unloading counter is the total number of mixing fabric carts minus 1, the host computer sends a feeding completion signal to the press.

[0024] After the press mold completes pressing and returns to the receiving position, the unloading counter is reset to 0, and the last mixed fabric trolley runs to the unloading position to unload.

[0025] After the lid of the material tank is closed, the material tank drive mechanism drives the material tank to rotate.

[0026] The host computer calculates the speed of the walking motor based on the stirring time, and triggers the first-in-first-out algorithm to calculate the input when it reaches the unloading waiting position.

[0027] The tank position sensor detects the position of the tank in real time.

[0028] When the front-end mixing fabric truck is unloading, the back-end mixing fabric truck moves to the unloading waiting position to wait. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] See Figure 1 , Figure 2 This embodiment provides an intelligent control method for multiple fabric mixing carts using a ring-shaped feeding mechanism for a press, which is carried out according to the following steps:

[0036] S1. Install the ring frame 1. Install multiple support legs 101 at the bottom of the ring frame 1. Install the ring guide rail 2 on the ring frame 1. Install the ring sliding contact line 3 on the inner side of the ring guide rail 2. Install the main control box 4 on the support legs 101.

[0037] S2. Place the first mixing fabric cart 5, the second mixing fabric cart 6, the third mixing fabric cart 7, and the fourth mixing fabric cart 8 on the annular guide rail 2. Each mixing fabric cart includes a frame 501, a drive shaft, drive wheels 502, a walking drive mechanism 503, a bracket 504, a material tank 505, and a material tank drive mechanism 506. Axles are rotatably mounted at both ends of the frame 501, and drive wheels 502 are mounted at both ends of the axles. The axles are driven by the walking drive mechanism 503 mounted on the frame 501. The walking drive mechanism 503 is a geared motor, and the walking motor of the walking drive mechanism 503 is a variable frequency motor. The walking drive mechanism 503 is equipped with a walking encoder 507.

[0038] Horizontal trunnions are symmetrically installed on both sides of the middle part of the material tank 505. The trunnions are rotatably connected to the bracket 504 through the bearing seat. A material tank position sensor 508 is installed on one side of the trunnion, and the trunnion on the other side is connected to the output shaft of the material tank drive mechanism 506 through the coupling. The material tank drive mechanism 506 consists of a motor and a reduction mechanism. The motor is a variable frequency motor. The material tank drive mechanism 506 drives the material tank 505 to rotate and mix materials.

[0039] Power on the equipment and test run it to check its operating status. Manually run the four mixing fabric carts to check whether the walking motor, walking encoder 507, and material tank position sensor 508 are operating correctly. Manually operate each action of the equipment to check whether the action is correct.

[0040] S3, the annular frame 1 is equipped with a loading position, a cover closing position, a mixing area, a loading waiting position, a discharging position, and three discharging waiting positions. Figure 3 As shown), a proximity switch is installed at the loading position. When each mixing material cart runs to the loading waiting position, it triggers the manual initialization button, which automatically initializes the status of the equipment running angle, tank body, tank cover, etc.

[0041] S4. The host computer sets the loading position to 0 degrees, the lid-closing 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, and the loading waiting position to 330 degrees. The area between the lid-closing position and the first waiting position is the mixing zone. The host computer calculates the speed of the mixing fabric cart's travel motor based on each angle. During the mixing fabric cart's operation, the travel encoder 507 calculates the cart's angle and speed in real time, the material tank position sensor 508 detects the position of the material tank 505, and calculates the travel motor speed based on the set mixing time. Upon reaching the unloading waiting position, the first-in-first-out algorithm for pressing in is triggered.

[0042] S5. Initialization: The first mixing fabric cart 5 is positioned at 270 degrees. The second mixing fabric cart 6, the third mixing fabric cart 7, and the fourth mixing fabric cart 8 are placed sequentially after the first mixing fabric cart 5.

[0043] S6. Automatic start: The first mixing fabric cart 5 automatically moves to the 0-degree position, and the proximity switch is triggered, automatically setting the position of the first mixing fabric cart 5 to 0 degrees. The first mixing fabric cart 5 is then loaded with material. The second mixing fabric cart 6 detects that the distance between it and the first mixing fabric cart 5 is greater than 30 degrees and automatically moves forward. When the angle difference between the second mixing fabric cart 6 and the first mixing fabric cart 5 is 35 degrees, it decelerates and stops at 30 degrees. The third mixing fabric cart 7 and the fourth mixing fabric cart 8 then run in sequence.

[0044] S7. After the first mixing fabric car 5 is loaded, it moves to the 30-degree closing position and closes the cover.

[0045] S8. After the lid is closed, the first mixing cart 5 moves forward and starts timing. The material tank drive mechanism 506 drives the material tank 505 to rotate for mixing. When it reaches the 270° position, the mixing is completed. The mixing time is 120 seconds.

[0046] S9. The first mixed fabric cart 5 moves forward to the first unloading waiting position, the travel motor stops, and the material tank drive mechanism 506 drives the material tank 505 to a vertical position, ready to enter the unloading position for unloading. The first mixed fabric cart 5 continues to move forward to the unloading position at 270 degrees for unloading, and the tank cover opens for unloading. After the first mixed fabric cart 5 unloads, the unloading counter of the host computer increments by 1.

[0047] S10, the second mixing fabric cart 6 and the third mixing fabric cart 7 repeat steps S6-S9 in sequence to load and unload materials. 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 fabric cart 8 is in the first unloading waiting position to wait.

[0048] S11. After the press mold completes pressing and returns to the receiving position, the unloading counter is reset to 0. After the fourth mixing material cart 8 receives a signal that the value of the unloading counter is less than 3, the fourth mixing material cart 8 runs to the unloading position to complete the unloading, and then runs to the loading position to load.

[0049] S12. All mixed fabric carts complete one feeding cycle.

[0050] This invention utilizes a single-unit fabric mixing vehicle control system to control the walking frequency conversion drive system, the mixing frequency conversion drive system, and the limit and sensor detection system to complete the process actions of the individual equipment. The intelligent central control system controls the movement of the entire fabric mixing equipment and enables wireless information exchange with other equipment via a wireless transmission system. The entire system operates automatically, requiring no operator intervention.
