Description of the Related Art Conventionally, an X-ray foreign substance inspection apparatus has been used to detect foreign substances (metal, stone, glass, synthetic resin, bone, rubber, etc.) contained in foods and pharmaceuticals. This X-ray foreign matter inspection device irradiates an object to be inspected with X-rays and detects the foreign matter contained in the object to be inspected based on the image data of the transmitted X-rays. Further, the X-ray foreign matter inspection apparatus includes a line sensor to analyze a transmission image of the inspected object on the conveying device and detect the foreign matter contained in the inspected object. If a foreign substance is detected, it is removed from the transport device.

A cover is provided to shield the wires from leaking to the outside unnecessarily. However, in actuality, for example, a belt conveyor may be used to convey the inspection object to the X-ray irradiation position, but a space for the inspection object to pass through is required in the carry-in path and the carry-out path. . Then X from this space
The line leaks. Therefore, various methods have been taken to prevent the leakage of X-rays, one of which is, for example,
Rubber goodwill containing lead is suspended to prevent leakage of X-rays. However, as shown in the figure, the above goodwill is pushed up by the object to be inspected and turned up to form a leak space. This space changes irregularly in size depending on the loading of the inspection object. The larger the space, the greater the amount of X-ray leakage and the greater the danger to the human body.

くあり改善が望まれていた。Further, particularly when a long object passes through, the leakage space becomes large and the time during which the space is generated becomes long, so that X-rays are exposed for a long time. There are other problems unique to rubber goodwill containing lead. This kind of goodwill is usually divided in the vertical direction, and is called vertical division, in which a few pieces hang down in strips. However, it is relatively heavy, and due to the rigidity of goodwill, the inspected object is pushed back without being conveyed to a predetermined position, and there are many problems such as the inspected object staying in front of the goodwill without being pushed up, and improvement is desired.

However, the present invention solves the above-mentioned problems of the prior art, and provides an inexpensive X-ray foreign matter inspection apparatus that can be widely used regardless of the size of the inspection object.

This is because there is a dimensional difference 11 between the height dimension of the object to be inspected and the refraction part of the goodwill. In the present invention, the goodwill up-and-down mechanism 10 is designed to eliminate this dimensional difference 11.
Is provided. In the example of FIG. 3, if the dimensional difference 11 between the object to be inspected and the refraction part of the goodwill is adjusted by the goodwill up / down mechanism, the X-ray leakage space disappears as shown in FIG.

検査物にあわせて事前に調節することも行っている。FIG. 6A is a diagram for explaining a case where an X-ray leakage space 27 is generated in the widthwise gap between the goodwill and the object to be inspected. A guide is usually provided on the conveyor so that the object to be inspected is conveyed at the center of the conveyor. However, there are various dimensions in the width direction of the object to be inspected, and the dimension does not always coincide with the vertical division dimension (vertical division) of the goodwill, and a leak space occurs. Therefore, FIG.
As shown in (B), for example, even if a leak space occurs in the goodwill 6 at the entrance, the goodwill 7 closer to the X-ray generation part or the goodwill 6 at the entrance can be adjusted to various widths so as to match the width dimension of the inspection object. We also prepare goodwill and adjust it in advance according to the inspection object transported in lot units.

(B) In the goodwill 7 closer to the X-ray generation part, as a method of closing a space where there is space, vertical goodwill is used as two streaks (two pieces), and each is moved laterally to match the width dimension of the inspection object. It indicates that As a result, even if the goodwill 6 at the entrance creates a space with the object to be inspected, the goodwill 7 on the inner side cancels the projection space and the leakage of X-rays becomes extremely small. What has been described above applies to the other sets of goodwill 8 and 9 as well.

も確保できる。As described above, the conventional X-ray leakage protection goodwill has a structure in which a plurality of vertically striped strips are arranged, so that not only the leakage space becomes large, but also the transportation is hindered. There was a drawback that there were things. According to the present invention, in addition to the vertical division (referred to as vertical division), a structure capable of refracting in multiple stages in the horizontal direction (referred to as horizontal division) is adopted, so that the inspection object can be minimized when passing through the goodwill. The space is formed, and the leakage of X-rays can be suppressed to the minimum. Furthermore,
Due to the difference in size of the inspected object, the upper part of the inspected object matches the fold of the goodwill so that the gap is minimized by moving the goodwill up and down, so even if the inspected object changes,
X-ray leakage can be reduced and human safety can be secured.
