1、 Preparation before startup and production

1. Power on and system login

Close the main power switch and other required circuit breakers inside the power cabinet, close the cabinet door, rotate the voltage universal transfer switch on the cabinet door, and observe that the voltage of each phase is normal. Set the control power switch knob above the power cabinet door to the "on (1)" position, the console is powered on, the power indicator light on the panel is on, and the weighing terminal instrument is powered on for initialization. (for the basic parameter setting and adjustment of the weighing terminal, please refer to the manual of the terminal) start the display and industrial computer host, and the operating system will start to the desktop state. Find the software shortcut icon of production control and double-click to open the software. In the process of start-up, the software detects and collects the signals of field position switch, material level switch and sensor, and then enters the main monitoring interface.

To enter the software for any operation, you must log in first. There are two kinds of identities of login users: administrator user login can set the management and use rights of each part of the system; operator user login can only execute the specified operation items.

Click the "operator login" button in the monitoring interface with the mouse, and enter the user name and password in the system login window. The existing user name "a" is provided to the user, and the password is empty by default, which can also be set by the user himself.

2. Monitor the main interface and the parameters to be set in operation

In the main monitoring interface, animation simulating the production process and state is mainly arranged. At the corresponding position of the screen process, the mouse control buttons are distributed at the same time. The meanings of the parameters in the upper left corner are as follows:

Methods to modify the above parameters: double click the data next to the corresponding label with the mouse to pop up the modification dialog box, input new parameters in the dialog box, and click OK.

In the lower left corner of the screen, there are four parameters: proportioning number, delivery order number, volume per plate, and number of plates per vehicle. These are the data related to the mixing of the truck in the task list. When the production data is transferred from the upper computer, these data will be changed accordingly, so as to judge whether the data transfer is successful.

In the main monitoring interface, click the "debug" button in the upper line to open the debugging interface. The upper part of the debugging interface is related to the parameters of the batching scale, and the lower part of the debugging interface is the parameters of the aggregate batching scale

Fine aggregate balance pulse opening time____ It refers to the time of opening the door by flashing of aggregate in the precise weighing stage, with the unit of millisecond.

Adjustment of discharging sequence____ It refers to the discharging sequence of aggregate weighing bucket after the completion of aggregate batching.

Adjustment of discharging interval____ It refers to the time interval of discharging aggregate in sequence. For example, 9 seconds between aggregate 1 and aggregate 2 means that 9 seconds after the unloading of aggregate 1, aggregate 2 starts unloading.

Out of tolerance pause setting____ It refers to the larger allowable error value of the material batching process. When the value is exceeded, the program will pause and wait, and a prompt dialog box will pop up. When the operator clicks OK, the program will continue to run.

In the parameters of batching scale, it is necessary to emphasize the detailed setting of quantitative and drop. The detailed design and quantification is suitable for the control mode with two batching speed processes, namely fast batching and slow batching. Fine setting is to set the amount of slow ingredients. The drop is also known as the advance of material stopping. It means that when the system detects that the blanking amount has reached the target amount, it will send out a signal to stop batching. Because it takes a certain time from sending the stop batching signal to completely closing the blanking door, the actual blanking amount is often more than the target amount. In order to make up for this part of the excess material, it is required to close the blanking door when the batching action fails to reach the target quantity. This part of the amount in advance is called the gap.

Setting strategy: the setting of fine quantitative setting should take into account the accuracy and efficiency of batching. In order to achieve the batching accuracy, the slow batching action must be carried out for a part of the time in the action process. In order to take into account the efficiency, the slow batching time should not be too long. The gap setting should be estimated according to the batching situation. In the production process, the program will detect the batching data and adjust it automatically.

Setting method: Method 1: right click the discharge port of the batching scale in the main monitoring interface and select the corresponding menu for setting; method 2: open the debugging interface (as shown in Figure 6) and click the corresponding position to set; method 3, set in the instrument.

Note: powder scale and liquid scale do not have slow batching process.

3. The method of data setting and down transmission in production

In the monitoring main interface, click the "management system" button to pop up the login window, enter the user name (common name "a") and password to enter the main interface of management software.

The main function of data management software is to collect and manage the data of ingredients and customers. In the production, the formula, the volume of each truck and the number of mixing plates of each truck should be transmitted to the weighing terminal instrument and PLC. In addition, these data should be connected with the customer's information. There are two ways to do this. One is the Mo mode, which is to edit the Mo into a mo. The other is non task list mode, which can input relevant data information directly in the main management interface.

Before this work, there is a work should be done first, that is, the relevant data in the database has been entered. When the mixing plant management system is used for the first time, it is also necessary to maintain all the required product data systematically (see the operating instructions of the management system for specific operation). The so-called "maintenance" is to input and check the required data to ensure that they are complete and accurate. Data maintenance mainly includes formula data, customer data, product data, staff and vehicle data. This work should be completed before production.

To download data in the form of a task list, you must first edit a task list. The method of editing a task list is described in detail in the description of the data management system. A task list is equivalent to a production task issued by production scheduling, which contains formula data, contract number, engineering data and other information.

To start the production of a vehicle or a plate of materials, click the Add button in the editing area of the data management main interface to add a new shipping order (Note: if there are no changes in the Mo and the volume per vehicle, you can start production directly. Before printing the delivery note, you only need to change the vehicle number). In the upper left corner of the editing area, check the small box in front of the task mode to select the task mode. Next, select the task name from the drop-down text box list behind the task mode. At this time, you can see that the relevant data in the task list appears in the corresponding position in the editing area. Set the number of production units and the number of plates per vehicle, select the vehicle number and driver, and click the save / production button, then the computer will start to download the data.

The main marking content in the data download appears in the lower left corner of the monitoring interface. Check that the data on the monitoring interface and the data transmitted are correct. At this time, if the motor startup and other following preparations are ready, you can click the start production button on the monitoring interface or the cycle start or single disk start on the operation panel to start the production process.

In the editing area of the data management main interface, click the Add button to add a new shipping order. In the upper left corner of the editing area, the small box in front of the task mode is not checked, and the task mode is not selected. Input the relevant data information directly in the main management interface, select the formula data, and click the save / production button to download the data. After checking the data, start production.

4. Starting motor

Start the air compressor first and prepare for the air pressure. Press the air compressor start button above the power cabinet door to start the air compressor, and the indicator light in the button is on. After the air compressor starts and reaches a certain pressure (there is an indicator light at the lower right corner of the monitoring interface), then start the mixing motor. After the mixing motor is started, the inclined belt transmission motor is started again, and the flat belt motor starts automatically after the inclined belt motor is started. After the mixing motor and belt motor are started, the corresponding animation in the monitoring interface is started for indication.

2、 Automatic operation

After the task is passed down successfully, the production can be started after the pressure of the gas path meets the production requirements. Click the "start production" button on the monitoring screen of the upper computer or press the "automatic" button on the operation console, and then press the "cycle start" or "single disk start" button, the cycle indicator light will be on, and the system will start to run automatically. During the operation, the monitoring screen will dynamically display the equipment operation status, mixing time, the number of plates in the car, etc.

In the process of automatic operation, according to the actual needs, the production process can be suspended batching, suspended feeding, prohibited discharging, scale buckle, reset operation (the menu of scale buckle and reset can be called out by right-click the box at the bottom of the scale bucket), intervene in the production process, and modify the operation parameters.

"Suspension of batching" - refers to suspending the batching process of the next plate, and the ongoing batching will be completed.

"Suspended" refers to the next feeding process in progress.

"No discharging" - means that the mixer is prohibited from discharging, and the unloading in progress will be completed.

"Buckle scale" - refers to when the material weighing exceeds the target value and exceeds the error, operate this function to leave a part of the weight in the weighing bucket. When the next weighing, the weighing value starts from the left weight. Click the scale button, the dialog window appears, enter the required deduction value, and confirm. Note: this function cannot be used for the accumulated scale.

"Reset" - refers to setting the value of the weighing terminal display instrument to zero.

In the automatic process, the program is executed according to the action cycle of batching, feeding, feeding, mixing and discharging. The operator should pay attention to observe and deal with the abnormal situation in time. When the automatic operation is finished, the cycle indicator light goes out.

When the automatic operation is to be terminated, press and hold the "cancel production" button on the monitoring screen of the upper computer, or press and hold the "manual" button on the operation panel until the cycle indicator light goes out, and the automatic production process is terminated. If the automatic operation is terminated in the production process (the cycle indicator is off), the unfinished process needs to be handled manually before the next automatic cycle can be started.

If any abnormality is found in the production process, it can be switched from automatic to manual. At this time, the production process is suspended and the cycle indicator light is not off. After manually handling the fault, switch back to automatic, and the cycle continues to be completed automatically.

3、 Manual operation

Manual operation can be divided into upper computer manual operation and console manual operation.

1. Manual operation of upper computer

The monitoring screen of the upper computer is equipped with operation buttons of each control object. No matter in manual or automatic situation, these buttons can be clicked by the mouse to open and close the door, vibrate a certain motor and intervene and control the production process.

2. Manual operation of console

For manual operation on the console, press or click the "manual" button to switch the operation mode to manual mode, then the buttons on the control panel can be operated. When the cycle indicator is not off, and then switch to the automatic state, the production will continue from

Move on.

When the upper computer can not be used due to failure, the key switch should be turned to the corresponding position when the powder and additive are manually mixed.

7、 Introduction of computer monitoring system

The monitoring interface is developed with configuration software. Through communication with PLC and weighing instrument, it can collect and simulate the field data and control the process. Monitoring software and data management software are independent of each other, and they communicate with each other through independent database.

There is a row of text buttons at the upper end of the monitoring interface. Click these buttons to open the corresponding interface or carry out corresponding operation. The following is a brief introduction to some buttons and other functions of the monitoring software.

1. The operator can log in to the system administrator to manage the equipment. The number of operators can be increased or decreased. Different permissions can be set for each operator. The setting range is 0-999.

2. Operator login: after the operator logs in with his user name and password, he can effectively operate and control various functions on the interface.

3. Operator exit: after the "operator exit" is executed, the operator's authority will be cancelled, which can prevent the operation of personnel not within the authority. It is necessary to re-enter the account and password before entering the system again.

4. Debugging: the interface can directly display and modify the formula value, fine setting quantitative value and drop value of the instrument, and can directly display the dynamic value and record value of material weighing.

5. Some instructions on the monitoring interface: when a certain material in the formula is activated, the sign text on the corresponding material storage bin is displayed in green, and the corresponding powder and additive storage bin are also marked with "tick"; the color of the lower horizontal bar of the powder bin is green, indicating that the powder has reached the material level, and red indicates that the material has been lower than the lower limit The material will not be able to be batched.
