Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
Embodiment one
As shown in figure 1, a kind of boxboard color autocontrol method, comprises the following steps：
S10, online color detector is provided, online color detector is detected to the color of finished paper, obtains finished product
The color data of paper.
Specifically, online color detector can be color difference meter, and online color detector is used for just from life on generation line
Color into finished paper out is detected.In boxboard generating process, in order to ensure the quality of boxboard, boxboard
Color can not have aberration, namely can not have deviation with default color.
In the present embodiment, color data is the L values of finished paper color, (L values expression brightness, the expression of a values are red for a values and b values
Green degree, b values represent champac degree respectively).Certainly, in other embodiment, color data is alternatively the L values of finished paper color
With a certain class value among a values or L values and b values or a values and b values；Further, in the case of some specific generations, number of colours
According to be also the L values of finished paper color, a values and b values any one of.
The color data that S20, online color detector will be detected is transferred to PLC.
In the present embodiment, signal transmission can be realized between online color detector and PLC.Specifically, exist
Line color detector is transmitted color data with specific data mode by the specific communication protocol between PLC
To PLC.
S30, PLC draw discharging instruction according to color data.
In the present embodiment, PLC show that discharging instruction is specially according to color data：The first generation according to needed for
The L values of the pre-set color of boxboard, a values and b values, write load calculation procedure；Calculated to simultaneously PLC write-in load
Program；The L values of the finished paper that PLC will be received, a values and b values are substituted into load calculation procedure and run load
Calculation procedure, obtains the corresponding discharging instruction of color data.
Discharging instruction is transferred to measuring pump by S40, PLC.
In the present embodiment, signal transmission can be realized between measuring pump and PLC.Specifically, PLC is led to
The specific communication protocol crossed and measuring pump between will discharge to instruct and be transferred to measuring pump with specific data mode.
S50, measuring pump are according to the corresponding dyestuff of discharging instruction output.
In the present embodiment, measuring pump is specially according to the corresponding dyestuff of discharging instruction output：Open the dye of corresponding color
The dog-house of material and to production pond in deliver corresponding amount dyestuff.Further, the dog-house tool of the dyestuff of corresponding color is opened
Body is：The dog-house for opening orchil or the dog-house for opening weld or the dog-house for opening black dyes.When
So, in other embodiment, the color of dyestuff is alternatively other colors.
The color data of finished paper is detected by online color detector, after PLC is processed color data
Draw discharging instruction and discharging instruction is transferred to measuring pump, measuring pump is realized according to the corresponding dyestuff of discharging instruction output
Closed-loop control to boxboard color, can in time be made up when deviation occurs in the color of finished paper by the dispensing of dyestuff, can be continued
Produce the boxboard for meeting pre-set color requirement.The boxboard color autocontrol method that the present embodiment is provided, it is right to realize
Boxboard color is automatically controlled.
Embodiment two
A kind of boxboard color automaton is included in line color detector, the number of colours for detecting finished paper
According to；PLC, PLC is electrically connected with online color detector, for processing color data and being sent out according to color data
Discharging instruction；Also include measuring pump, measuring pump is electrically connected with PLC, for receiving discharging instruction and referring to according to discharging
The corresponding dyestuff of order output.
Specifically, Fig. 2 is the schematic diagram of the boxboard color automaton that the present embodiment is provided, it is first determined
The L values of the color of the boxboard of generation, a values and b values；The face of online color detector boxboard first to being generated on production line
Color is detected and is obtained the L values of color of finished paper, a values and b values；L values, a values and b that online color detector will be detected
Value is transferred to PLC；PLC computing is carried out according to the load calculation procedure being previously written and draw every set L values,
A values and the corresponding discharging instruction of b values, measuring pump is transferred to followed by discharging instruction；Measuring pump is according to discharging instruction to production
The dyestuff of corresponding color and quantity is delivered in pond；Ultimately produce out finished product boxboard；The finished product boxboard that generates continue by
Line color detector is detected that such boxboard color automaton just can carry out closed loop control to the color of boxboard
System.
Because of the change of the conditions such as environment temperature the color of boxboard may be caused to have deviation in process of production.This reality
The boxboard color automaton for applying example offer can realize closed-loop control, thus regardless of when boxboard color with
Default color has deviation, and boxboard color automaton can be adjusted correspondingly to eliminate deviation.
In the present embodiment, also including display, for showing the color data for detecting.
Obviously, the above embodiment of the present invention illustrates example of the present invention just for the sake of clear, and is not right
The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no need and unable to be exhaustive to all of implementation method.It is all this
Any modification, equivalent and improvement made within the spirit and principle of invention etc., should be included in the claims in the present invention
Protection domain within.
