Now, the second detecting position 1012 of normal tested material 101 has not moved into the focusing 92 of the second detecting position, secondary signal
The light intensity of detection unit 1112 is unchanged, and the second gas circuit control unit 122 does not work.
When normal tested material 101 is moved to position shown in Fig. 8, the first detecting position 1011 of normal tested material 101
Detection light-emitting area 81 is have passed through, 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 the first electric signal, and the first gas circuit control unit 112 is closed, gas channels 21
It is disconnected again；Now, the normal tested detecting position 1012 of material 101 second is still also less than the focusing 92 of the second detecting position, the
Binary signal detection unit 1211 does not work without electric signal output, the second gas circuit control unit 122, and gas channels 21 are to disconnect；
When normal tested material 101 is moved to position shown in Fig. 9, the first detecting position 1011 of normal tested material 101
Detection light-emitting area 81 is have passed through, the gas channels 21 of this section are to disconnect；Now, normally it is detected the detecting position of material 101 second
1012 to the focusing 92 of the second detecting position, and secondary signal detection unit 1211 has electric signal output, and the control of the second gas circuit is single
Member 122 works, and this section of gas channels 21 are conductings, still, because the first gas circuit control unit 112 is closed, and are normally detected material
101 in whole displacement process, and two gas circuit control units are all without work simultaneously, therefore blow gun or extension module will not work,
Normally the tested normal shift of material 101 is gone over；It will not be removed.
Figure 10 is referred to, if the position of tested material is abnormal condition, as shown in figure 4, being the quilt under pathosis
Sample material 102, when the tested material 102 under pathosis is moved to position shown in Figure 10 along F directions, under pathosis
First detecting position 1011 of tested material 102 is not to the position of the first detecting signal unit 1111, the first signal detection list
Member 1111 will not export the first electric signal without light intensity change, the first detecting signal unit 1111, 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 detection unit 1211, the second gas circuit control unit yet
122 also do not work.
Figure 11 is referred to, when the tested material 102 under pathosis is moved to position shown in Figure 11 along F directions, instead
First detecting position 1011 of the tested material 102 under normal state is believed to the position of the first detecting signal unit 1111, described first
Number detection unit 1111 has light intensity change, and the first detecting signal unit 1111 exports the first electric signal, the first gas circuit control unit
112 work；Now, the second detecting position 1012 has also arrived the position of secondary signal detection unit 1211, the second gas circuit control unit
122 also work.Gas channels 21 are connected, and valve or extension module 31 are worked, and the tested material 102 under pathosis is picked
Remove.
In the utility model, only worked simultaneously in the first gas circuit control unit 112 and the second gas circuit control unit 122
When, compressed gas can just flow to valve or extension module 31 by gas channels 21, valve or extension module 31 is worked,
First gas circuit control unit 112 and the work of the second gas circuit control unit 122 can in no particular order, as long as two gas circuit control units are same
