Detailed ways

In order to ensure the accuracy of the batching weight, the present invention adopts a double-station structure, that is, the 4# station is used for the main ingredient, and the 8# station is used for the auxiliary material. In view of the characteristics of large weight of main material and relatively large absolute error value within the allowable range of precision, the feeding method of large auger is adopted to increase the feeding speed. The weight of auxiliary materials is small, the precision is high, and the control is very difficult. For this reason, a special small auger is used for feeding, which improves the feeding accuracy.

The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited.

The fire clay batching device with full digital automatic control provided by the present invention has a structure as shown in Figure 1 and Figure 2. In view of the large number of raw materials in the fire clay formula, the proportion of the main material is small and the proportion is high, and the proportion of auxiliary materials is many and the proportion is low. , the device has designed a double-station batching bin structure, one batching bin is at 4# station 17, and consists of 4 large bins 15 to form a large bin group; the other batching bin is at 8# station 2, composed of 8 Two small silos 3 form a small silo group, which not only ensures the accuracy requirements when disposing auxiliary materials, but also meets the speed requirements when disposing main materials. When batching, the material delivery trolley 12 is used to receive and weigh the materials at the 4# and 8# stations respectively. After the batching is completed, the material transportation trolley 12 moves to the 1# station 16, waiting for the porter to fill the ingredients The dolly hopper 10 of the car is transported away, and then the dolly hopper 10 without charging is replaced to carry out the next round of batching.

In the small silo group, the lower end of each small silo 3 is equipped with a small auger 1 (small electric auger powder conveyor), and a small auger 1 is installed between the small silo 3 and the small auger 1. Feed bin inserting plate 9 is used for isolating unused feed bins or by adjusting the inserting plate gap, the feeding speed can be controlled. When working, the powder in the small silo 3 is sent by the small auger 1 to the trolley hopper 10 waiting below the outlet. The motor of the small auger 1 adopts the first frequency converter 25 for speed control. The speed is high and the output speed is high. Fast, low speed, and higher accuracy of weighing. The control system determines the running speed of the small auger motor by reading the value of the load cell 13, which can ensure the accuracy of small material allocation and speed up the speed of small material allocation. . A set of ventilation and dust removal system is designed above the small silo group, as shown in Figure 1. The ventilation and dust removal system includes quick-release dust filter element 4, injection electromagnetic valve seat 5, electromagnetic pulse valve 6, pneumatic butterfly valve 7, and dust suction duct 8. When the workman adds raw materials to the small material bin 3, he first opens the small material bin 3 door, and when the programmable logic controller (PLC) 21 detects that the door is opened by the door limit, it will automatically open the pneumatic butterfly valve 7 (turn off the electromagnetic valve). Pulse valve 6) for air extraction and dust removal, close the door of the small material bin 3 after feeding, and PLC automatically opens the injection electromagnetic pulse valve 6 (closes the pneumatic butterfly valve 7) and recoils the quick-release dust filter element 4 to prevent the filter element from being blocked by dust. The dust collection system fails.

In the described large silo group, the lower end of each large silo 15 is equipped with a large auger 11 (large electric auger powder conveyor), and a large auger 11 is installed between the large silo 15 and the large auger 11. Feed bin flashboard 18 is used to isolate unused feed bins or by adjusting the flashboard gap to control the feeding speed. When working, the powder in the large silo 15 is sent by the large auger 11 to the trolley hopper 10 waiting below the outlet. The motor of the large auger 11 uses the second frequency converter 31 for speed control. The speed is high and the output speed is high. Fast, low speed, and higher accuracy of weighing. The control system determines the running speed of the auger motor by reading the value of the load cell 13, which can ensure the accuracy of configuring large materials and speed up the configuration of large materials. . When feeding large feed bin 15, directly put into the large feed bin 15 li with the special-purpose large woven bag of filling material directly with the crane, so do not design the ventilation and dust removal system here.

The material delivery car is mainly composed of a material delivery trolley 12, a load cell 13, a motor of the material delivery trolley and a reducer 14, and is mainly used for loading powder from the trolley hopper 10 to each station, and docking the loaded powder Weigh it. The motor and reducer 14 are used to provide power for the trolley, so that the trolley can travel back and forth on a fixed track, and can decelerate and stop when it encounters a limit switch. The load cell 13 is installed under the hopper 10 of the trolley to detect the trolley. The total weight of the hopper 10 and the powder therein controls the working status of each electric auger by monitoring the weight change before and after feeding. After the configuration of large and small materials is completed, the material transport trolley 12 stops on the 1# station 16, and the worker lifts the trolley hopper 10 on the material transport trolley 12 parked at this station with a crane, and replaces it with a new empty trolley hopper 10. After that, continuous production can be done here.

The electromagnetic pulse valve 6 can be a DMF electromagnetic pulse valve.

The structure of the electric control system is shown in Fig. 4: the programmable logic controller 21 (PLC) can be the CP1H product of Omron Corporation. A set of upper computer man-machine control interface adopted is realized by industrial computer and display 19, wherein the industrial computer can adopt Advantech IPC-510MB industrial computer of Taiwan, and the display can adopt Great Wall L2282 display. The PLC control program is written by CX-Programmer7.3 programming software. The human-machine interface establishes a communication connection with the PLC through a serial port of the industrial computer, and keeps exchanging data; establishes a communication connection with the weighing instrument 23 (weight indicator) through another serial port of the industrial computer, and reads the current weight data in real time. The PLC receives data and instructions from the upper computer, and provides corresponding output based on external input buttons and switch 20 and other conditions, and controls the operation of components 22 composed of valves, augers, electric pumps and trolley motors.

The control mechanism of the auger motor is shown in Figure 5, which consists of a group of circuit breakers, frequency converters, contactors, intermediate relays, and auger motors with the same structure. Among them: the first circuit breaker 24, the first frequency converter 25, the first contactor 26, the first intermediate relay 27 and the first auger motor 28 form a blanking control unit, which controls 8 small augers 1 to unload in sequence; The second circuit breaker 29, the second frequency converter 31, the second contactor 32, the second intermediate relay 30 and the second auger motor 33 form another unloading control unit, which controls four large augers 11 to unload in turn. The 4 large augers 11 are controlled by a frequency converter 25, and the 8 small augers 1 are controlled by another frequency converter 31, that is, the control mode of 1 for 4 and 1 for 8 is adopted (Fig. 5). When feeding, the programmable logic controller (PLC) 21 can respectively control the first contactor 26 and the second contactor 32 to pull in according to the recipe needs, and switch to the current first auger motor 28 and the second auger motor 33 in turn, saving installation space and cost.

The fire clay batching device with full digital automatic control provided by the invention fully takes into account the situation during equipment maintenance. Once the feeding auger breaks down and needs to be disassembled for maintenance, it is impossible to disassemble when there is residual material in the silo, otherwise the raw materials will all leak to the ground, so the small silo insert 9 and the large silo insert 18 are designed , as shown in Figure 1, when the auger needs to be removed for maintenance, insert the inserting plate inward to block the discharge port, which can effectively prevent material leakage and facilitate maintenance and repair. In addition, adjusting the insertion depth of the insert can also assist in adjusting the speed and accuracy of blanking.

The fully digital automatic control fireclay batching device provided by the present invention is easy to operate, and has two modes of operation, manual and automatic. In the manual mode, the control button 20 on the panel can be used to manually open the component 22 to check whether it works normally. In the automatic state, it accepts the automatic control of the upper computer system to perform automatic batching, see Figure 3. When the system self-inspection passes and the machine tool status is normal, the worker selects and sets the fire clay formula and batches to be produced through the man-machine control interface, and then clicks the man-machine interface to start the batching button, and then the PLC controls the twisting of each corresponding silo. The dragon motor rotates and unloads the material in turn until it reaches the specified weight and stops. The whole batching process is automatically completed by the system. After a batch is completed, the PLC compares the number of batches set by the worker with the current batch. When all batches have been completed, the batching process is all over, and the system enters the state of completed and waiting for the next batch; if it does not reach the specified The number of batches, PLC automatically controls the continuous batching until the set number of batches is reached. The above description is for the case of setting only one recipe (batch cycle). When multiple recipes are set continuously, the PLC will execute the first recipe first. The process is as above. After the first recipe is completed, the PLC will The second recipe will be automatically and continuously configured, and executed in sequence until all the input recipes are completed (recipe cycle). When a fault occurs during the configuration process, the system will automatically pause, and the host computer interface will display fault information for maintenance engineers to query. After the fault is resolved, click the device start button to continue unloading from the breakpoint.

In addition, by designing a set of programs for automatically calculating the batching amount and the metering sensor installed on the receiving trolley, the operator only needs to input the batching formula and batch number through the man-machine interface, press the start button, and the device will automatically batch , and can automatically record the actual proportioning quantity of each batch of materials for future reference, which can reduce the quality problems of products caused by wrong ingredients and help craftsmen to continuously improve product quality.

The present invention has also designed a cover as shown in Table 1 and Table 2 automatically calculates the program of batching amount.

In Table 1 and Table 2, No. 1-8 is defined as the number of the small hopper, and No. 9-12 is defined as the number of the large hopper. In the fire clay formula table, the order of discharging is first selected, and No. 9 is first released in the above table. Hopper, then put down the No. 10 hopper, ... and so on. The second step is to define the weight of the discharged material, which is displayed in percentage in the table. According to the weight 300 in the "production formula", the actual weight can be calculated specifically for the weighing control of the control device use.

The actual weighing situation is recorded and saved by the database. Table 3 and Table 4 are the various parameters of the actual database showing the actual work of batches 1~3, 4~6 respectively. Table 3 and Table 4 are provided with calculated theoretical values And the actual weighing value can be used by craftsmen to inquire and supervise and check the production status.
