The principle of work that the present invention detects machine is as follows:
At first packaged food to be detected is sent into from the input end 21 of conveying device, wherein the packaged food to be detected situation that contains deoxidation reagent is divided into and contains normal deoxidation reagent, contains the deoxidation reagent of inefficacy and without three kinds of situations of deoxidation reagent;
When packaged food to be detected transports through material inductor 3 by feedway, material inductor 3 has detected the packaged food process, then send energizing signal to controller for timing switch 4, trigger the time meter 41 beginning timing of controller for timing switch 4, clocking value is T;
T when packaged food to be detected passes through deoxidation reagent inductor 5, is divided into following two kinds of situations in the time:
(1) the first situation: packaged food to be detected contains normal deoxidation reagent, at this moment, during this packaged food process deoxidation reagent inductor 5, normal deoxidation reagent attracts the magnet 54 of one or more deoxidation reagent inductor 5 upwards to beat, deoxidation reagent inductor 5 will be exported a reset signal, and this reset signal is sent to controller for timing switch 4, the time meter 41 of controller for timing switch 4 stops timing and resets, controller for timing switch is controlled and is removed mechanism's outage wait, removing the coil L outage of the solenoid actuated parts 64 of mechanism waits for, the packaged food that contains normal deoxidation reagent continues to slide to from exporting 22 end outputs the plate 14 that connects material by feedway,
(2) the second situation: packaged food to be detected contains the deoxidation reagent of inefficacy or without deoxidation reagent, at this moment, this packaged food is through deoxidation reagent inductor 5, because the deoxidation reagent that lost efficacy or can not attract the magnet 54 of any deoxidation reagent inductor 5 upwards to beat without deoxidation reagent, deoxidation reagent inductor 5 does not have signal output, controller for timing switch 4 is controlled and is removed mechanism's energising action, remove the coil L energising of the solenoid actuated parts 64 of mechanism, for example the coil L to solenoid actuated parts 64 passes into a pulse current, coil L attracts to order about telescopic boom 641 and does the indentation campaign, telescopic boom 641 pulls the outer boom 623 of rotating shaft lower end and orders about rotating shaft 62 and rotate through the first extension spring 7, when rotating shaft 62 is rotated, the dead man 63 that is connected with the rotating shaft upper end will swing, at this moment, ram 66 on the dead man other end outwards swings and beats to the deoxidation reagent that contains inefficacy or without the packaged food of deoxidation reagent, make this packaged food eject load-transfer device, coil L outage afterwards, the second extension spring 8 pulls the outer boom of rotating shaft lower end and orders about rotating shaft toward back rotation, dead man resets.
A kind of method of inspection whether packaged food the inside contains deoxidation reagent that detects of the present invention comprises the steps:
A, packaged food to be detected put into feedway and transported by feedway, set successively material inductor, deoxidation reagent inductor and remove mechanism along the throughput direction of feedway;
B, when packaged food to be detected is transported to the material inductor by feedway, the material inductor detects packaged food process to be detected, and energizing signal is sent to controller for timing switch, and the time meter that triggers controller for timing switch begins timing, and time meter presets a clocking value T;
C, at T in the time, packaged food to be detected is transported through the deoxidation reagent inductor by feedway, and by the deoxidation reagent inductor, whether packaged food to be detected the inside is contained deoxidation reagent and survey;
D, when the deoxidation reagent inductor detects packaged food to be detected the inside and contains deoxidation reagent, reset signal is sent to controller for timing switch, controller for timing switch is controlled and is removed mechanism's outage wait, and the packaged food that contains deoxidation reagent continues to be transported and exported by feedway; When the deoxidation reagent inductor detected packaged food to be detected the inside without deoxidation reagent, controller for timing switch was controlled and is removed mechanism's energising action, will eject feedway without the packaged food of deoxidation reagent.
