When the cigarette bar YT is used, the two inductance sensors 400 are firstly arranged on the production detection line along the illustrated transmission direction, when the cigarette bar YT has the problem of pack missing, the electric signals induced by the two inductance sensors 400 can generate obvious signal difference, and then the controller triggers the action signals of the rejecting mechanism 200 according to the signal difference, so that the cigarette bar YT with the problem of pack missing is accurately discharged out of the production line; after the structure is adopted, the packet missing detection precision of the quantum pulse packet missing detector 100 can be effectively supplemented, the occurrence probability of packet missing accidents when the packet missing detector cannot identify that the tobacco packet in the tobacco rod is toppled (for example, transverse packet) or misplaced can be greatly reduced only by setting the quantum pulse packet missing detector, and further powerful guarantee is provided for higher product delivery qualification rate.
Preferably, if the controller determines that the tobacco rod is short of the packet by the signals of the two inductance sensors 400, the tobacco rod directly passes through the quantum pulse packet-lack detector 100 (without detection by the quantum pulse packet-lack detector 100) and then reaches the rejecting mechanism 200 for rejection.
The maximum height of the tobacco rod can be slightly higher than the height of a normal tobacco rod when the tobacco bag in the tobacco rod on the conveyor belt has unpacking phenomenon, if the inductive sensor is at the normal working height, the inductive sensor and the ultra-high tobacco rod can be interfered in position when passing through the inductive sensor, and then the tobacco rod is detained on the current detection station. With such consideration, it is preferable that the present application further provides the stand 500 with a height adjusting mechanism 510 as shown in fig. 1, the height adjusting mechanism 510 being electrically connected with the controller.
