Therefore, the relative position of the cigarette with respect to the inspection area at the present time is grasped using the pulse signal from the rotary encoder 32, and the determination process of S108 is performed. If an affirmative determination is made in S108, the process proceeds to S109, and if a negative determination is made, the processes in and after S102 are repeated, and the process of acquiring the corrected received intensity by irradiating the filter 1 with the inspection electromagnetic wave is performed again.

  • the process proceeds to S110.
  • S110 based on the peak reception intensity Vp, a determination is made regarding the capsule arrangement state in the filter 1 to be inspected. Specifically, when the peak reception intensity Vp is smaller than the predetermined threshold value Rv, it is determined that the capsule 1a is in the normal arrangement state in the filter 1 (processing of S111).
  • the fragrance liquid is locally dispersed in the filter 1 without being dispersed. Therefore, the presence state of the fragrance liquid is reflected in the reflected electromagnetic wave, and the peak reception intensity Vp is preferably a small value. Considering this point, the determination of S110 is performed.

  • the fragrance liquid is dispersed in the filter 1. Therefore, the reflection effect of the fragrance liquid is hardly reflected in the reflected electromagnetic wave, and the peak reception intensity Vp becomes a relatively large value.
  • the determination of S110 is performed. Also, the cigarette 2 having the filter 1 determined to be abnormal in S112 is excluded from the drum 30 in S113.
  • a known exclusion device (for example, a device that eliminates the compressed air) is used.

  • the inspection electromagnetic wave and the reflected electromagnetic wave generally pass on the same path in the inspection space between the probe antenna 23 and the filter 1. Therefore, when the inspection electromagnetic wave passes through the filter 1 and is received by the probe antenna 23 as a reflected electromagnetic wave, it passes through the same part of the filter 1, so if the inspection electromagnetic wave passes through the capsule 1a.

Abstract

L'invention concerne un appareil d'inspection de filtre qui vérifie si un objet prédéterminé conçu pour être placé dans un filtre d'article à fumer est correctement agencé. L'appareil d'inspection de filtre est pourvu : d'une unité d'émission pour émettre une onde électromagnétique d'inspection d'une fréquence prédéterminée vers un filtre d'article à fumer à inspecter ; une unité de réception pour recevoir depuis le filtre une onde électromagnétique réfléchie de l'onde électromagnétique de l'inspection émise par l'unité d'émission ; une unité d'antenne qui est placée face au filtre et propage l'onde électromagnétique d'inspection et l'onde électromagnétique réfléchie ; une unité d'acquisition pour acquérir, sur la base d'un signal de réflexion obtenu par l'unité de réception, des informations prédéterminées concernant l'intensité ou le déphasage du signal de réflexion, qui sont associées à l'agencement de l'objet prédéterminé dans le filtre ; et une unité de détermination pour déterminer si l'objet prédéterminé est correctement agencé dans le filtre sur la base des informations prédéterminées acquises par l'unité d'acquisition. Cette configuration réduit la taille de l'appareil d'inspection.
