<p>The invention provides a system for sensing a cigarette filter, comprising: a plurality of rotary conveyance drums (12) delivering a first cigarette filter and second cigarette filters into which the first cigarette filter is divided by a cutter; two sensors (18) disposed adjacent to the rotary conveyance drum (12) to detect the second cigarette filters; an opto coupler connected to the two sensors (18) and operated by AND logic; a HIP connected to the opto coupler, it controlling a device of supplying cigarette filters to reject a cigarette having defects; and, a PLC connected with the HIP, it controlling the device of supplying cigarette filters, wherein the two sensors (18) detect active charcoal filters located at both ends of the second cigarette filters, the HIP controls the device such that the cigarette having defects are rejected when signals sensed by the sensors (18) are different from signals sensed from the normal active charcoal filter, the PLC controls the operation and stop of the device by performing the processes except the process of rejecting the cigarette having defects.</p> |
