Embodiment 1
A kind of method that control material is launched is present embodiments provided, Fig. 1 is the flow chart of this method, as shown in figure 1, should
Method includes following processing：
Step 101：Obtain the target weight of material to be put；
In the present embodiment, material to be put can be color masterbatch, can also be unclassified stores, and the present embodiment does not do specific limit
It is fixed.Wherein, the target weight of material to be put can be manually entered by operating personnel, can also be distributed and referred to by control device
Mark.
Step 102：Material is launched according to target weight controlled motor and controls weighing device to weigh the material launched；
In a step 102, it is that controlled motor is moved so as to control and the rotation of motor-driven screw rod that controlled motor, which launches material,
Turn to take material to be put out of, complete the dispensing of material to be put.
Step 103：When the weight of remaining material to be put is not more than the first weight, controlled motor launches the second weight every time
The material of amount, after every material for having launched the second weight, controlled motor is out of service；
In the present embodiment, on the basis of material to be put is color masterbatch, the second weight is not more than 0.1 gram.
Step 104：Weighing device is controlled to weigh the weight for having launched material when motor is out of service, until missile
The weight of material reaches target weight, and controlled motor stops launching material.
The method that the present embodiment provides can also include：After the target weight of material to be put is obtained, mesh is calculated
Indicated weight amount subtracts the 3rd weight that the first weight obtains；Calculate the first object period needed for the material for launching the 3rd weight；
Controlled motor and weighing device are run simultaneously within the first object period, to launch material and weigh the material launched.
The method that the present embodiment provides can also include：Before the material that controlled motor launches the second weight every time, meter
Calculate the second object time needed for the material for launching the second weight；Based on this, controlled motor launches the material of the second weight every time,
After every material for having launched the second weight, controlled motor operation out of service can include：Controlled motor runs the second mesh
It is out of service after between timestamp.
The method that the present embodiment provides also includes：After control weighing device weighs the material launched, according to target
The weight for having launched material that weight and weighing device weigh calculates the weight of remaining material to be put, so as in above-mentioned step
Can be according to the weight of remaining material to be put come the dispensing of control material in rapid 103.
In the present embodiment, when the quality of remaining material to be put is not more than the first weight, controlled motor often launches the
The material of two weight is out of service, and now weighing device can then avoid motor vibrating to having launched weighing for material
The influence brought so that the weight for weighing to obtain is more accurate, so that it is guaranteed that material dispensing is more accurate.
Embodiment 2
The present embodiment so that material to be put is color masterbatch as an example, say by the method launched to control material provided by the invention
It is bright.
The present embodiment is by control logic and method, and the course of work launched to original color masterbatch machine is modified, by color masterbatch
Weighing for machine is decomposed with motor operation feeding process, caused by avoiding vibration when motor operation to the full extent
Error caused by weighing sensor.
In the present embodiment, control unit interface is received using an analog input port (4-20mA or 0-10V) and used
In the signal for the pressure sensor weighed, an analog output port (4-20mA or 0-10V) is used for controlling feeding motor
Operation, RS485 communication interface connects manual operator, the start and stop of the target weight weighed and operation set by manual operator.
Fig. 2 shows the flow chart for the method that the control material that the present embodiment provides is launched, as shown in Fig. 2 this method bag
Include following processing：
The time required for 0.1 gram of color masterbatch of submitting when motor is run with minimum speed can be tested out first.Step 201,
Electricity operation on color masterbatch machine；
Step 202：Target weight is set on manual operator；
Step 203：Controller controls weighing operation to be carried out simultaneously with launching materials handling；
Inside controller when receiving the target weight of manual operator setting, first calculate remaining material to be put and be less than mesh
Time required for 1 gram of indicated weight amount (i.e. above-mentioned first weight), within this time, analog output port output run signal makes
The normal feeding of motor, controller monitor the data for the pressure sensor weighed by analog input port in real time；Perform step
204：Judge to have launched the weight of material and the difference of the target weight of setting whether within 1 gram, it is determined that having launched material
Weight with setting target weight difference when within 1 gram, change color masterbatch machine working method, perform step 205.
Step 205：Controller controls weighing operation with launching materials handling alternately；
After changing working method, according to the time required for 0.1 gram of color masterbatch of calculated submitting in advance, first controlled motor fortune
Row sends out the time that 0.1 gram of color masterbatch needs.Motor is out of service after reaching run time, and now controller detects analog quantity at once
The weighing data that the pressure sensor that input port receives is sent back, because now motor is in halted state, so pressure
Force snesor will not be by influence caused by motor oscillating.Perform step 206：Whether the quality that material has been launched in detection reaches mesh
Indicated weight amount.If now detect that the current weight for having launched material is not reaching to target weight, return to step 205：Then again
Secondary stopping sense weight, 0.1 gram of color masterbatch is sent out by analog output port controlling motor again, send out electricity after 0.1 gram of color masterbatch
Machine sense weight again out of service.Above procedure constantly repeats, until the color masterbatch of the dispensing weight and target weight that detect
After consistent, step 207 is performed：Controller judges to complete this feeding process, prepares the feeding of beginning next time and work.
In the present embodiment, because the real-time of controller is very high, the speed of response and detection port is all in Millisecond
Not, so although the feeding process of second stage has been divided into many single steps and carried out, but total time is still very short, complete
It disclosure satisfy that requirement of the color masterbatch machine to feeding time entirely.
