's.
Refer to Fig. 3 to Fig. 5, Fig. 3 is the tested material 101 under normal condition, it has two detecting positions, one first inspection
Location 1011, another is the second detecting position 1012, and wherein, the first detecting position 1011 is the material marking on tested material, by
Upstream producer indicates, and the second detecting position 1012 is a detection edge, is also feature of tested material itself, for other
Different materials it is also possible to before use, determine corresponding detecting position according to practical situation, repeat no more here.
Fig. 4 is the tested material 102 under anomic, and the tested material 102 under anomic is actually normally tested
Material 101 flip horizontal 180 degree is formed, and this is the unwanted state of next procedure institute, needs to reject.
Fig. 5 is that multiple normally tested materials 101 are in line, and has wherein pressed from both sides the tested material 102 of abnormality.
Refer to Fig. 6, Fig. 6 is a kind of detection structural representation of the embodiment for detecting tested material.Described detection
Structure includes material road segment section 1, is provided with the first detecting signal unit 1111 and secondary signal detection on described material road segment section 1
Unit 1211, wherein, described first detecting signal unit 1111 and secondary signal detector unit 1211 are all optical fiber, the first signal
Detector unit 1111 is used for detection the first detecting position 1011, and described secondary signal detector unit 1211 is used for detection the second detecting position
1012, described secondary signal detector unit 1211 has focussing force, during installation by puberty optical registration second detecting position out
Focusing 92, the focusing 92 of the second detecting position above detection labelling optical fiber mold insert 9 has absorption effects, the second detecting position
Focusing 92 when no object blocks, secondary signal detector unit 1211 no electric signal output, when there being object to pass through, can block
The focusing 92 of the second detecting position, secondary signal detector unit 1211 has electric signal output；Certainly, secondary signal detector unit
1211 may be designed in correlation optical fiber, and the focusing 92 of described second detecting position will be turned into unthreaded hole.
In figure, the first detecting signal unit 1111（Actually the first optical fiber）Detection light-emitting area 81 be fixed on detection labelling light
In fine mold insert 9, when no object blocks, the first detecting signal unit 1111 no signal of telecommunication is defeated for the detection light-emitting area 81 of the first detecting position
Go out, when there being object to pass through, meeting occlusion detection light-emitting area 81, the first detecting signal unit 1111 has electric signal output.First inspection
Location only just has signal output in detecting position region, remaining position no signal output.
The described first gas circuit control unit 112 of in figure and described second gas circuit control unit 122 are invisible, are all connected on
In gas channels, gas channels one terminate compressed air source, another termination valve or extension module 31.
Refer to Fig. 7, Fig. 8 and Fig. 9, when normally tested material 101 moves to position shown in Fig. 7 along F direction, normally
First detecting position 1011 of tested material 101 enters into the detection zone of the first detecting position, just to detection light-emitting area 81, now,
First detecting signal unit 1111 is because light intensity change is beyond the given threshold scope of the first detecting signal unit 1111, the first signal
Detector unit 1111 can produce first signal of telecommunication, is conveyed to the first amplifying circuit 1112, after first signal of telecommunication is exaggerated, by the
One delay circuit 1113 controls described first gas circuit control unit 112 to open, and the gas channels 21 of this section are in aeration status.But,
Now, normally the second detecting position 1012 of tested material 101 has not moved into the focusing 92 of the second detecting position, secondary signal
The light intensity of detector unit 1112 is unchanged, and the second gas circuit control unit 122 does not work.
When normally tested material 101 moves to position shown in Fig. 8, normally the first detecting position 1011 of tested material 101
Have passed through detection light-emitting area 81, now, the first detecting signal unit 1111 has been returned to given threshold scope because of light intensity change
Interior, the first detecting signal unit 1111 no longer exports first signal of telecommunication, and the first gas circuit control unit 112 is closed, gas channels 21
It is disconnected again；Now, normally tested material 101 second detecting position 1012 is still also less than the focusing 92 of the second detecting position, the
Binary signal detector unit 1211 no electric signal output, the second gas circuit control unit 122 does not work, and gas channels 21 are to disconnect；
When normally tested material 101 moves to position shown in Fig. 9, normally the first detecting position 1011 of tested material 101 has been
Cross detection light-emitting area 81, the gas channels 21 of this section are to disconnect；Now, normal tested material 101 second detecting position 1012
To the focusing 92 of the second detecting position, secondary signal detector unit 1211 has electric signal output, the second gas circuit control unit 122
Work, this section of gas channels 21 are conductings, but, because the first gas circuit control unit 112 is closed, normally tested material 101 exists
In whole displacement process, two gas circuit control units all do not work simultaneously, therefore blow gun or extension module will not work, normally quilt
Sample material 101 normal shift is gone over；Will not be disallowable.
Refer to Figure 10, if the position of tested material is abnormal condition, as shown in figure 4, being the quilt under anomic
Sample material 102, when the tested material 102 under anomic moves to position shown in Figure 10 along F direction, under anomic
First detecting position 1011 of tested material 102 is not to the first detecting signal unit 1111 position, described first signal detection list
Unit 1111 no light intensity change, the first detecting signal unit 1111 will not export first signal of telecommunication, and the first gas circuit control unit 112 is not
Work；Now, the second detecting position 1012 does not arrive the position of secondary signal detector unit 1211, the second gas circuit control unit yet
122 also do not work.
Refer to Figure 11, when the tested material 102 under anomic moves to position shown in Figure 11 along F direction, instead
Often the first detecting position 1011 of the tested material 102 under state is to the first detecting signal unit 1111 position, described first letter
Number detector unit 1111 has light intensity to change, and the first detecting signal unit 1111 exports first signal of telecommunication, the first gas circuit control unit
112 work；Now, the second detecting position 1012 has also arrived the position of secondary signal detector unit 1211, the second gas circuit control unit
122 also work.Gas channels 21 are connected, and valve or extension module 31 work, and the tested material 102 under anomic is picked
Remove.
In the present invention, only when the first gas circuit control unit 112 and the second gas circuit control unit 122 work simultaneously, pressure
Contracting gas just can flow to valve or extension module 31 by gas channels 21, so that valve or extension module 31 is worked, and first
Gas circuit control unit 112 and the second gas circuit control unit 122 work can in no particular order, as long as two gas circuit control units same period
Open, valve or extension module 31 work.
Certainly, when N is more than or equal to 3 situation, the applicant repeats no more here.Any one or more gas circuits control
Unit is opened, but the requirement that the gas circuit control unit reaching conjunction portion is opened, the present invention is considered as normally tested material 101, fair
Permitted to move ahead；Otherwise, it is treated as the tested material 102 under anomic, disallowable.
