Since the line absorption coefficient is slightly different but slightly different,
There is a method of comparing and detecting the difference in the contrast of the X-ray fluoroscopic image using a line inspection apparatus, but it is difficult to realize because the contrast difference is not so large. Also, due to the viscosity of the contents of the sealed container, the outer shape is easily deformed for long-term storage,
There has been a problem that it is difficult to make a pass / fail judgment due to a difference in thickness with a small probability depending on the degree of deformation.

搬送され、第2のベルトコンベア3に塔載される。Next, the operation of the inspection apparatus for a sealed container configured as described above will be described. 1 and 2, a sealed container 2 is mounted on a first belt conveyor 1, conveyed in the direction of arrow A in the figure, and mounted on a second belt conveyor 3.

出器（図示は省く）で検出し加振機10に知らせる。The bells of the first and second belts and the steps of the conveyors 1 and 3 are reduced so that the sealed container 2 is smoothly transferred when the sealed container 2 is transported from the first belt conveyor 1 to the second belt conveyor 3. Uses a small-diameter roller 5. Then, the second belt conveyor 3 detects the mounting of the sealed container 2 with a detector (not shown) and notifies the vibrator 10.

めておくものとする。Then, the vibrator 10 vibrates the second belt conveyor 3 in a predetermined direction with a predetermined frequency range and a predetermined strength. Here, it is assumed that the values of the predetermined direction, the predetermined frequency range, and the predetermined strength are determined in advance by experiments or numerical calculations.

立ち音を発する。この音をマイクロホン11で集音する。Assuming that the contents of the sealed container 2 mounted on the vibrated second belt conveyor 3 are, for example, nutrients mainly composed of dairy products, if they are putrefactive, the fat component and the protein component are coagulated. It becomes a viscous body and absorbs sound even when excited, and hardly emits sound. Or, it is known that even if a sound is emitted, the frequency is low because the component is a viscous body. The nutrient does not solidify unless it rots and remains a liquid. Therefore, when the nutrient is shaken, a wave is generated on the liquid surface and a sound is generated. This sound is collected by the microphone 11.

(The function of this filter may be provided in any one of the amplifier 12 and the controller 15 in addition to the microphone 11, or may be provided with a vibration-proof material and a sound-absorbing material.)

機16の軸を動作させて排斥させる。The sound is amplified by the amplifier 12, the type of sound is determined by the intensity and frequency of the sound by the control device 15, and if the sound has a frequency at which the liquid surface has a wave, the second belt conveyor is directly used. 3 and the sound intensity is below a predetermined value, and if it is below a predetermined frequency, the contents become viscous and decaying, so the second and third Timing is set based on the conveyor speed of belt conveyors 3 and 4,
The shaft of the rejection device 16 is operated in a direction orthogonal to the transport direction of the third belt conveyor 4 to perform rejection.

Although mechanical vibration due to 0 is applied, sound pressure is applied by a speaker, the response of the sealed container 2 is detected by a microphone, and the state of the contents of the sealed container 2 is determined by the difference in sound volume and frequency. good. The configuration of this inspection device is composed of a microphone 11, an amplifier 12, a vibrator 10, and a control device 15, so a small product is selected from the components and assembled and electrically connected with a cord or the like. It can be installed in a space and can be easily installed in a short time.
