本考案は電子線照射装置に関する。 The present invention relates to an electron beam irradiation device.

【従来の技術】[Conventional technology]

電線照射装置において、電線、チューブその他の長尺体の被照射体を照射室に 搬送し、これに順次電子線を照射するようにしたものは既によく知られている。 この場合電子線を照射したときに発生するX線が外部に漏洩するのを防止するた めに、照射室に隣接して予備室を設け、この予備室と照射室との間の遮蔽壁およ び予備室と外部との間の遮蔽壁とにスリットを設け、このスリットを通して被照 射体を通過するようにしている。 In electric wire irradiation equipment, electric wires, tubes, and other long objects to be irradiated are placed in the irradiation chamber. It is already well known that a device is transported and sequentially irradiated with an electron beam. In this case, in order to prevent the X-rays generated when irradiating the electron beam from leaking to the outside, For this purpose, a preliminary room is set up adjacent to the irradiation room, and a shielding wall and a shielding wall are installed between this preliminary room and the irradiation room. A slit is provided in the shielding wall between the preliminary room and the outside, and the illuminated object is passed through this slit. It is designed to pass through projectiles.

【0003】 図3はその従来構成を示し、1は照射室、2は予備室、3は照射室1と予備室 2との間の遮蔽壁、4は予備室2と外部との間の遮蔽壁、5、6は各遮蔽壁3、 4に形成されてあるスリット、7は前記したような被照射体、8は電子線を照射 する照射窓、9は被照射体7の搬送をガイドするプーリーである。0003 Figure 3 shows its conventional configuration, where 1 is the irradiation chamber, 2 is the preliminary chamber, and 3 is the irradiation chamber 1 and the preliminary chamber. 2 is a shielding wall between the preliminary room 2 and the outside, 4 is a shielding wall between the preliminary room 2 and the outside, 5 and 6 are each shielding wall 3, A slit is formed in 4, 7 is the object to be irradiated as described above, and 8 is a slit for irradiating the electron beam. 9 is a pulley that guides the transportation of the object 7 to be irradiated.

【0004】 従来では照射室1からスリット5を通って予備室2に、また予備室2からスリ ット6を通って外部にX線が漏洩しないようにするため、両スリット5、6の傾 斜を同じ方向とし、スリット5の予備室2側の端部Aより、スリット6の予備室 2側の端部Bを高い位置に設定するようにしている。0004 Conventionally, the irradiation chamber 1 passes through the slit 5 to the preliminary chamber 2, and from the preliminary chamber 2 to the slit. In order to prevent X-rays from leaking outside through the slit 6, the slopes of both slits 5 and 6 are With the oblique directions in the same direction, from the end A of the slit 5 on the auxiliary chamber 2 side, the auxiliary chamber of the slit 6 The second end B is set at a higher position.

【0005】 このように構成すれば、スリット5を通って予備室2内に入ったX線は、その まま直進してスリット6内に入ることはできない。もし入り得るとすれば、複数 回にわたって予備室2内で反射を繰り返す必要がある。しかしこのように複数回 にわたって反射すれば、X線は減衰してしまうので、スリット5を通って外部に 漏洩するX線は微弱なものとなる。[0005] With this configuration, the X-rays entering the preliminary chamber 2 through the slit 5 will be It is not possible to go straight and enter the slit 6. If possible, multiple It is necessary to repeat the reflection in the preliminary chamber 2 several times. But multiple times like this If the X-rays are reflected over the slit 5, they will be attenuated. The leaked X-rays will be weak.

【0006】 しかしこのような構成によれば、端部Aより端部Bを高く設定しなければなら ないため、予備室2内ではプーリー9を少なくとも2個必要とする。したがって それだけ構成が複雑となる。また被照射体はプーリー9に多く転接するほど、そ の摩擦によって切断し易くなるので、プーリー9の数は少ない程よい。[0006] However, with this configuration, end B must be set higher than end A. Therefore, at least two pulleys 9 are required in the preliminary chamber 2. therefore The configuration becomes that much more complicated. Also, the more the irradiated object is in contact with the pulley 9, the more The fewer the number of pulleys 9, the better, as the friction will make it easier to cut.

【考案が解決しようとする課題】[Problem that the idea aims to solve]

本考案は、照射室から外部にX線が漏洩しないように構成するにあたり、予備 室内のプーリーの数を従来よりも少なく構成することを目的とする。 This invention is designed to prevent X-rays from leaking from the irradiation chamber to the outside. The purpose is to configure the number of indoor pulleys to be smaller than before.

【課題を解決するための手段】[Means to solve the problem]

本考案は、照射室と予備室との間の遮蔽壁に設けるスリットと、予備室と外部 との間の遮蔽壁に設けるスリットとを、互いに逆方向に傾斜させて形成し、両ス リットの間に被照射体の搬送方向をV字状に変換させる単一のプーリーを予備室 内に設置したことを特徴とする。 This invention consists of a slit in the shielding wall between the irradiation chamber and the preliminary chamber, and a slit between the preliminary chamber and the outside. The slits provided in the shielding wall between the A single pulley that converts the conveyance direction of the irradiated object into a V-shape between the lit parts is installed in the preliminary chamber. It is characterized by being installed inside.

【作用】[Effect]

両スリットはその傾斜方向が逆であり、また被照射体は予備室内において、V 字状に方向転換されて搬送される。このような両スリットの位置関係からして、 照射室から最初のスリット内を直進して予備室内に入ったX線は、そのまま次の スリット内を直進して外部に漏洩することは全くない。また最初のスリット内を 通って予備室内に入ったX線は、次のスリットを通って外部に漏洩するには、予 備室内を繰り返して反射していく必要がある。それまでにはX線は減衰してしま うので、外部にはほとんど漏洩しないようになる。そして予備室内には唯一のプ ーリーを設置しておくだけで足りるので、構成は簡単となる。 Both slits have opposite inclination directions, and the object to be irradiated is placed in the preliminary chamber at V It is conveyed by changing direction in a letter shape. Considering the positional relationship between both slits, The X-rays that go straight from the irradiation chamber through the first slit and enter the preliminary chamber go directly to the next slit. There is no possibility that it will go straight through the slit and leak to the outside. Also inside the first slit The X-rays that have passed through the slit and entered the auxiliary chamber must be It is necessary to repeatedly reflect inside the preparation room. By then, the X-rays will have attenuated. Therefore, there is almost no leakage to the outside. And there is only one printer in the spare room. The configuration is simple because it is sufficient to install the

【実施例】【Example】

本考案の実施例を図1によって説明する。なお図3と同じ符号を付した部分は 同一又は対応する部分を示す。スリット5は照射室1側から予備室2側に向かっ て低くなるような傾斜とされてある。またスリット6は予備室6側から外部に向 かって低くなるような傾斜とされてある。 An embodiment of the present invention will be described with reference to FIG. The parts with the same symbols as in Figure 3 are Indicates the same or corresponding parts. The slit 5 goes from the irradiation chamber 1 side to the preliminary chamber 2 side. The slope is such that the slope is low. In addition, the slit 6 is directed from the preliminary chamber 6 side to the outside. The slope is said to be lower than before.

【0011】 予備室2内には唯一のプーリー9が設置されてある。このプーリー9によつて 被照射体7は予備室2内で搬送方向がV字状に方向変換される。このような構成 によれば、照射室1からスリット5内を直進してくるX線がそのままスリット6 内に直進することは全く起こらない。[0011] Only one pulley 9 is installed in the preliminary room 2. By this pulley 9 The conveyance direction of the irradiated object 7 is changed in a V-shape within the preliminary chamber 2 . A configuration like this According to Going straight inward never happens.

【0012】 また図2に示すように、スリット5内を照射室1から直進してきたX線10が 外部側の遮蔽壁4の内側のみを照射するようにし、かつこの照射領域Mより上部 に、スリット6の端部Bが位置するようにしておけば、照射室1からスリット5 内を直進してくるX線がスリット6に入るためには、少なくとも3回以上の複数 回にわたつて予備室2の内壁に衝突し、反射しなければならない。そのたびに減 衰していくので、スリット6より外部に漏洩するX線の量は極めて僅かとなる。0012 In addition, as shown in FIG. Only the inside of the shielding wall 4 on the outside side is irradiated, and the area above this irradiation area M is If the end B of the slit 6 is located at In order for the X-rays traveling straight inside to enter the slit 6, it must be repeated at least three times or more. It must collide with the inner wall of the preliminary chamber 2 several times and be reflected. decrease each time As the X-rays attenuate, the amount of X-rays leaking to the outside from the slit 6 becomes extremely small.

【0013】 そして予備室2内には、一つのプーリー9を設置しておくだけで足りるので、 従来構成に比較して構成がそれだけ簡単になるとともに、被照射体7のプーリー 9に接する回数は少なくなるので、したがって被照射体7の摩擦による断線など の事故の発生回数は減少する。[0013] And since it is sufficient to install one pulley 9 in the spare room 2, The configuration is much simpler than the conventional configuration, and the pulley of the irradiated object 7 is Since the number of times it contacts 9 is reduced, there is a possibility of wire breakage due to friction of the irradiated object 7, etc. The number of accidents will decrease.

【考案の効果】[Effect of the idea]

以上説明したように本考案によれば、照射室から予備室を経由して外部に漏洩 するX線の量を減少させるのに、予備室内に1個のプーリーの設置で足りるよう になり、したがって構成を簡単にすることができるとともに、被照射体の損傷も 少なくすることができる効果を奏する。 As explained above, according to the present invention, leakage from the irradiation chamber to the outside via the preliminary chamber is possible. In order to reduce the amount of X-rays that are Therefore, the configuration can be simplified and damage to the irradiated object can be avoided. This has the effect of reducing the amount of water used.
