The pick-up unit of the utility model can also comprise camera head 17, camera for example, and it is configured to when detecting article through shading light electric switch 5, trigger the photo of taking article.
The method of operating of the utility model is described with the mode of concrete example below for example.
When two cover cartridge heaters and dangerous substance (for example drugs, explosive etc.) detection module 3 are installed, can realize continual detection, this moment, the workflow of the utility model device was following:
When detecting beginning, both sides dangerous substance detection module 3 all is in ready state, and drive motor 8 rotates counterclockwise, and through being with 9 synchronously synchronizing wheel 7 is rotated, and the filter screen 6 that is connected on the synchronizing wheel coupling shaft 15 is pulled out from the filter screen cartridge heater 4 on right side.Drive motor 8 belows are equipped with a pair of Hall switch 18, the number of turns that motion-control module 20 comes controlling and driving motor 8 to rotate through them.
Travelling belt 1 begins to rotate, and a pair of optoelectronic switch 5 has respectively been installed in both sides, screen support device 2 front and back end, and when goods mail process screen support device 2, when blocking two pairs of optoelectronic switches 5, camera 10 triggers the photo of taking a goods mail.
After goods passes through, and both sides dangerous substance detection module 3 is when all being in ready state, and drive motor 8 clockwise rotates, and filter screen 6 is drawn in the right side filter screen cartridge heater 4.4 pairs of filter screens 6 of filter screen cartridge heater heat so that the lip-deep material volatilization of the goods that filter screen 6 obtains.Right side dangerous substance detection module 3 begins to get into detected state.Gas through volatilization in the 10 extraction right side cartridge heaters 4 of the bleeding point on the right side cartridge heater 4 detects.If testing result is normal, then get into ready state again.If detect contraband goodss such as drugs or explosive; Then warning message and the photo packing that triggers shooting are sent to the supervisory personnel through network; The supervisory personnel carries out detailed inspection to these suspicious goods mails then; Right side dangerous substance detection module 3 gets into clean conditions simultaneously, cleans right side cartridge heater 4 and by the gas in its suction self inside, cleans the back entering ready state automatically that finishes.
When having goods to pass through again, and both sides dangerous substance detection module 3 is when all being in ready state, and drive motor 8 rotates counterclockwise, and filter screen 6 is drawn in the left side filter screen cartridge heater 4, and left side dangerous substance detection module 3 begins to get into detected state.So hocket in the left and right sides.
For practicing thrift cost, the equipment of this utility model also can only be installed a cover cartridge heater and a dangerous substance detection module, and another section is only installed a filter screen reel, but this moment possibly occur the situation that travelling belt 1 temporary transient motion is interrupted.Filter screen length on this device is than the length that two cover cartridge heaters and dangerous substance detection module are installed simultaneously, and when filter screen was drawn in right side filter screen cartridge heater fully, filter screen will be near filling up the whole filtering net cartridge heater.Its testing process is following:
When detecting beginning, right side dangerous substance detection module 3 is in ready state, and drive motor 8 rotates counterclockwise, and filter screen 6 unnecessary in the filter screen cartridge heater 4 with the right side is all pulled out.
Travelling belt 1 begins to rotate, and when goods mail process screen support device 2, when blocking two pairs of optoelectronic switches 5, camera 10 triggers the photo of taking a goods mail.
Pass through as the mail goods, and right side dangerous substance detection module 3 is in ready state, and also has unnecessary filter screen 6 not to be drawn into the right side cartridge heater on the filter screen reel 14.Drive motor 8 clockwise rotates, and will draw in the right side filter screen cartridge heater 4 from the filter screen that screen support device 2 left ends begin filter screen cartridge heater 4 parts to the right side.Right side dangerous substance detection module 3 begins to get into detected state.
The detection of going forward one by one does not so continuously have unnecessary filter screen on filter screen reel 14.At this moment, at this moment travelling belt 1 stop motion need stop to wait for a period of time; Treat that dangerous substance detection module 3 detections in right side finish; Again after being in ready state, once more filter screen 6 is all pulled out from the filter screen cartridge heater 4 on right side, detect according to as above step again.
Though above-detailed one cover is set or two cover detection modules carry out the method that the article surface adsorbent detects, the utility model is not limited thereto.The detection module of any right quantity can be provided according to actual needs.The utility model has been saved the needed a large amount of manpower and materials of traditional detection means through above-mentioned detection device and detection method.Particularly, the utility model has improved the speed of ion migration equipment testing goods mail, has reduced the personnel in the testing process and has dropped into.When the utility model utilizes travelling belt work; Mode with active contact friction part is accomplished the collection to the material grains on goods mail surface automatically; And auto injection and detection; Reduce the staff's in the conventional ion migration device detection procedure workload, improved work efficiency, realized the purpose of fast detecting.
It should be noted that example embodiment described herein has been described the preferred embodiment of the utility model, but limit the scope of the utility model never by any way.Those skilled in the art can be from the instruction content of preceding text, and each embodiment to the utility model carries out various combinations and distortion according to actual needs.Under the situation that does not break away from the utility model scope and essence,, can carry out variations and modifications to the pick-up unit and the detection method of the utility model according to the actual detection needs.
