Problems solved by technology

[0007] However, in this countermeasure, when a foreign object is detected from one inspection area near the center of the conveyor belt width direction, the exclusion device on the corresponding side operates, and at this time, there are two exclusion devices. The size (difference between small beans and potatoes) and other conditions, as well as the danger that the object to be inspected may move to the adjacent column when it is transported from the inspection position to the placement position of the exclusion device, the occurrence of such exclusion errors is of great importance to this The inspection device is fatal and cannot be practical and popularized

Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0021] figure 1 It is a configuration diagram of an embodiment of the present invention, and is a schematic diagram showing a mechanical configuration of a main part and a block diagram showing an electrical configuration in combination.

[0022] The object S to be inspected is loaded on the endless belt 11 of the conveying system 1 and conveyed at a constant speed. Above the conveying system 1, the X-ray tube 2 is arranged with its X-ray optical axis facing vertically downward, and at the same time, facing the X-ray tube 2, it is arranged vertically below it with the belt 11 sandwiched between them. Dimensional X-ray detector3.

[0023] The transmission system 1 includes: a belt 11, a driving roller 12 on which the belt 11 is wound, and a plurality of driven rollers 13, and is operated by a switch provided on the operation panel 4, and is driven by a motor that rota...

Abstract

A radiation detecting apparatus is provided to exactly exclude impurities by using a bad article excluding unit. A radiation detecting apparatus includes a radiation generating unit, a radiation detecting unit, a transportation unit, an image processing unit(5), and a bad article excluding unit(71). The radiation detecting unit is formed in one dimension or two dimensions. The radiation detecting unit includes a plurality of elements. The radiation detecting unit is arranged in opposition to the radiation generating unit. The transportation unit transports an article to be measured between the radiation generating unit and the radiation detecting unit. The image processing unit performs certification determination through image processing by means of an output of the radiation detecting unit.

Description

technical field [0001] The present invention relates to a radiation inspection device used for non-destructive inspection of medicines and foods, and in particular to a device suitable for inspecting whether foreign matter is mixed in non-packaged products such as soybeans, adzuki beans, potatoes, and wheat flour. Radiological examination device. Background technique [0002] In recent years, in the field of manufacturing food and the like, more and more attention has been paid to preventing contamination of foreign matter. A metal detector is generally known as a device for checking the presence or absence of foreign matter, but of course it is not suitable for inspection of stones, glass, and the like. In addition, there are inspection devices that rely on visible light and use CCD cameras, etc., but such devices are powerless against stones such as potatoes that grow embedded in the inside and foreign objects that adhere to the inner side of the object to be inspected. ...
