Value is compared with standard color value, and is further exported according to comparison result for indicating that detection zone is dry net or paper web
Corresponding detection signal.Wherein, based on paper web and dry net there are color difference, standard color value includes for indicating paper web
One standard color value, and the second standard color value for indicating dry net.
Multiple sampling components 111 output be the detection signal of paper web when, first judgment module 112 be used for according to multiple
The detection signal that sampling component 111 exports judges that paper web whether there is disconnected paper, and exports disconnected paper when there is disconnected paper and detect signal.
Specifically, sampling component 111 will test signal when detection zone is dry net and be arranged to first state, and detect
It will test signal when region is paper web and be arranged to the second state.First judgment module 112 will be in the detection signal of first state
Quantity be compared with preset threshold, if more than or be equal to preset threshold, then judge that paper web has disconnected paper, and export disconnected paper inspection
Survey signal；If being less than preset threshold, judge that disconnected paper is not present in paper web, does not export disconnected paper detection signal.For example, preset threshold is
Three, if the detection signal that three or three or more sampling components 111 export is in first state, it is disconnected to judge that paper web exists
Paper；If the detection signal only exported there are two sampling component 111 is in first state, judge that paper web has disconnected paper.
Multiple correction trigger assemblies 121 are used to trigger corresponding sampling component 111 respectively to standard face according to the paper signal that breaks
Color value is automatically corrected, i.e., corresponding sampling component 111 can detect when signal occurs in disconnected paper and obtain corresponding sample color
Value is used as standard color value.
Wherein, each correction trigger assembly 121 includes the first trigger element K1With the second trigger element K2, the first triggering member
Part K1It is used to indicate to the first standard color value or the second standard color value, i.e., the corresponding standard color value of paper web is still done
It nets corresponding standard color value to be corrected, the second trigger element K2It is used to indicate whether to be corrected.In practical application scene
In, the first trigger element K1With the second trigger element K2It can be relay.
Fig. 3 is the structural schematic diagram of the sampling component of one embodiment of the invention.As shown in figure 3, each sampling component 111 wraps
Include optical transmitting set 31, optical receiver 32 and the second judgment module 33.

Step S51: multiple color samples, and the sample color that multiple color samples are obtained are carried out to detection zone
Value is compared with standard color value respectively.
Step S52: it will test signal when detection zone is dry net and be arranged to first state, and be paper web in detection zone
When will test signal and be arranged to the second state.
Step S53: the quantity of the detection signal in first state is compared with preset threshold, and judgement is in first
Whether the quantity of the detection signal of state is greater than or equal to preset threshold.
If it is not, thening follow the steps S54；If so, thening follow the steps S55.
Step S54: disconnected paper is not present in paper web, does not export disconnected paper detection signal.
Step S55: there is disconnected paper in paper web, and exports disconnected paper and detect signal.
The present embodiment is exported according to comparison result for indicating that detection zone is multiple detection signals of dry net or paper web,
And judge that paper web whether there is disconnected paper according to multiple detection signals, so that exporting disconnected paper when there is disconnected paper detects signal.
Based on paper web and dry net there are color difference, standard color value includes the first standard color for indicating paper web
Value, and the second standard color value for indicating dry net carry out standard color value according to the detection signal triggering of disconnected paper automatic
When corrective action, it can use the instruction of the first trigger element and school carried out to the first standard color value or the second standard color value
Just, and using the second trigger element it is used to indicate whether to be corrected.
The auto-correction method of Fig. 4 and embodiment illustrated in fig. 5, can break each of paper detecting apparatus 10 as shown in FIG. 1 to FIG. 3
Element is corresponding to be executed, therefore the technical characteristic in above-mentioned auto-correction method be combined with each other the embodiment of composition, also belongs to this hair
Bright protection scope.
