Use Omron E6B2-CWZ6C2000P.Wherein, controller 501 uses logic controller, and it uses Siemens 200 series of PLC,
Supporting the high-speed pulse input of encoder 503, its thrustor 502 controlling to connect can use cylinder, and this cylinder is controlling
Start or stop under the control of device 501, to realize the pushing tow to the edible oil vessel on pipeline, by the edible oil vessel of pushing tow, logical
Cross and 1 vertically disposed point of pipeline of pipeline 101, be delivered to substandard product working area 102.
Additionally, in order to realize the detection to the edible oil vessel on pipeline, so that the camera in coding image acquisition unit 4
Can be triggered, to start image-acquisition functions, in the present embodiment, also include the edible oil vessel 2 on pipeline 1 is detected
Detector unit 10, the edible oil vessel on pipeline 1 is detected by this detector unit 10, with trigger camera start.This enforcement
In example, detector unit 10 uses photoelectric sensor, and as used the photoswitch of Omron E3JK-TR12-C-D-L 5, it uses
Laser-bounce principle, sensitivity and operating distance are adjustable, whenever having edible oil vessel through out-of-date, can be that high-speed industrial camera provides arteries and veins
Punching triggers signal, and meanwhile, this signal can also be simultaneously coupled to controller 501, provides count signal as system.
As above detection device, in use, comprises the steps:
By coding image acquisition unit 4, the laser coding of the edible oil vessel 2 on pipeline 1 carried out Image Acquisition, and will
The image obtained sends described main control unit 3 to；
The image that coding image acquisition unit 4 is obtained by main control unit 3 control character recognition unit 6 carries out character recognition
After, main control unit 3 control comparator 8, by described comparator 8, the character identified by described character recognition unit 6 is with described
The standard characters of memory element 7 storage is compared, to form the qualified inspection of the laser coding to described edible oil vessel surface
Survey.
Specifically, in pipeline 1 course of conveying, after edible oil vessel placed on it is detected unit 10 detection, detection
Unit 10 produces detection signal, works triggering image acquisition unit 4, and the laser on edible oil vessel 2 is sprayed by image acquisition unit 4
Code region carries out Image Acquisition, such as: memory element 7 internal memory contains multiple standard characters, each standard characters correspondence respectively
Different laser coding on each edible oil vessel, if one of them standard characters is " 2016-04-03R19S2054441 "；
After the corresponding laser coding on edible oil vessel is obtained by image acquisition unit 4, character recognition unit 6 after being identified, by
Character string and this standard characters of identification are compared by comparator 8, if comparison is consistent, then prove on this edible oil vessel
Laser coding is qualified, if inconsistent time, then be defective.For underproof edible oil vessel, it is pushed up repelling device 5
Push away, pushed away pipeline, meanwhile, coupled warning lamp 11 can be controlled by main control unit and carry out flash caution.Additionally,
Owing on the edible oil vessel that image acquisition unit 4 obtains, the area of picture is probably local area, therefore, when comparison, permissible
Consistency ration is set, as consistency ration is set to 80%, if the character string consistency ration of comparison result is less than 80%
, then be defective, more than 80% for qualified.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
