Device and method for detecting agglomeration of smoked sheets in smokebox

Abstract

The invention discloses a device and a method for detecting the agglomeration of smoked sheets in a smokebox. The device comprises a bracket, a conveyer, a radiation source, a radiation detector, a synchronous movement mechanism and a data acquisition and control system, wherein the bracket is arranged in a shielding casing, the radiation source and the radiation detector are installed on the synchronous movement mechanism, and the synchronous movement mechanism is fixed on stands at both sides of the conveyer; and the radiation source and the radiation detector move synchronously on the synchronous movement mechanism and measure a smokebox which passes through the middle of the synchronous movement mechanism and is conveyed by the conveyer to be measured, the data acquisition and control system collects a signal output by the radiation detector, the signal is analyzed according to an agglomeration judgment standard, and the agglomeration condition of smoked sheets in the smokebox to be measured is obtained. The device can measure the density variation DVR value of the smoked sheets of the smokebox more accurately, judges whether an agglomerate exists in the smokebox or not, and gives out the size and the position of the agglomerate; and moreover, the device adopts nondestructive examination and has the characteristics of high detection accuracy, high stability and reliability and the like.

Description

technical field [0001] The invention relates to the field of nuclear technology measurement, in particular to a detection device and a detection method for detecting agglomeration of sheet cigarettes in a cigarette box by measuring the density of the cigarette package. Background technique [0002] The patent application document with the patent application number 200610012088.4 describes the cigarette pack density on-line detection device and its method. It only replaces the destructive static nine-point detection with non-destructive detection, and it still gives the nine points of the cigarette pack. Density value, and calculate the density deviation of nine points accordingly. This cannot fully characterize the density distribution of the entire smoke box, so it is impossible to accurately give the deviation value of the entire smoke box density, let alone detect the existence of agglomerates and their specific location and size. In the silk-making process, the existenc...
