Description

【０００１】
【発明の属する技術分野】
本発明は、酸化によってダイオキシンとなる有害物に汚染された物（ＰＣＢ入りの変圧器やコンデンサ等）、即ち有害汚染物を切削して解体する場合にその切削屑を回収する方法に関する。
【０００２】
【従来の技術】
ＰＣＢを含有する機器を解体する一つの手段として、切削加工がある。そして、切削時の加工熱によってＰＣＢが酸化してダイオキシンになるのを防ぐ為に、種々の対策がなされている。具体的に言えば、切削速度を遅くするとか、不活性ガスの雰囲気下や、冷却ガスを吹き付けて切削する等である（例えば、特許文献１参照）。
【０００３】
【特許文献１】
特開２００３−３０２３１８号公報（第３頁）
【０００４】
【発明が解決しようとする課題】
しかしながら、切削速度を遅くすると時間がかかるので、効率が悪くなる。また、一般的な切削では切削油を用いるが、切削油を用いると切削油がＰＣＢに汚染されて二次汚染物となり、それが周囲に飛散すると、汚染が拡大することになるので、切削油を使わずに切削することが望ましい。切削油を用いずに切削した場合は、切削油を用いる仕方よりも切削箇所が高温となるので、ダイオキシンの発生を防ぐには切削速度を一段と遅くする必要があり、効率が格段に悪くなる。
【０００５】
一方、不活性ガスの雰囲気下や冷却ガスを吹き付けて切削する場合は、切削速度を上げることができるが、切削屑が不活性ガスや冷却ガスの及ばない箇所に飛散すると、加工熱によって酸化し、ダイオキシンが発生する恐れがある。
【０００６】
さらに、切削屑を回収しないと、切削した有害汚染物に切削屑が付着し、有害汚染物をその後に洗浄装置で洗浄してＰＣＢを取り除くときに、洗浄装置のフィルターやポンプ等に切削屑が詰まる等の不具合を誘発するおそれがある。
【０００７】
本発明は上記の問題を改善するために開発されたもので、その解決しようとする基本的な課題は、切削速度の向上、切削屑の飛散の防止及び切削屑の回収を図ることである。
【０００８】
請求項２の発明の固有の解決課題は、切削箇所の冷却効果の向上、切削屑の回収率の向上である。請求項３の発明の固有の解決課題は、切削工具自体の冷却効果の向上である。請求項４の発明の固有の解決課題は、切削箇所の冷却効果の向上である。
【０００９】
【課題を解決するための手段】
請求項１の発明は、有害汚染物を切削するときには、棒状の切削箇所の近傍にガスを吹き付けると共に、切削箇所の近傍でガスと切削屑を吸引して回収することを特徴とする。
【００１０】
近傍とは、ガスを吹き付ける場合であれば、ガスが切削箇所に効率良く当たり、風冷による冷却効果が充分に得られる程度の距離という意味で、吸引する場合であれば、切削屑を周囲に飛散させずに吸引して回収できる程度の距離という意味である。
【００１１】
ガスとは、その風冷作用によって刃部及び有害汚染物が冷却されるものであれば良く、水素、酸素など爆発の危険性のあるものを除く。具体的には、空気や窒素ガス、アルゴン等の不活性ガスが例示でき、不活性ガスであれば切削の加工熱によるダイオキシンの発生を効果的に防ぐことができる。
【００１２】
切削箇所の周囲を覆わずに切削しても良いが、ガスによる冷却効果及び切削屑の回収率を高めるには、請求項２の発明のように、切削工具の外側を筒状のカバーで取り囲み、切削工具とカバーの間にガス流通空間を形成し、ガスの吹き付け及び吸引を、ガス流通空間に対して行うことが望ましい。
【００１３】
カバーは一つであっても良いし、間隔をあけて複数設けても良い。
【００１４】
ガスの吹き付けは切削工具の周囲だけから行っても良いが、請求項３の発明のように、切削工具の軸線方向にガス供給路を形成し、切削工具の刃部先端部からガスを排出するものでも良い。
【００１５】
刃部先端部からガスを排出する方向は、特に限定されず、例えば、軸線方向であっても良いし、軸線方向に交差する方向であっても良い。
【００１６】
ガスの温度は特に限定しないが、冷却効果を高めるには請求項４の発明のように、ガスに常温よりも冷たいものを用いることが望ましい。
【００１７】
【発明の実施の形態】
本発明の有害汚染物の切削屑回収方法に使用する工作機械の第一例は、図１に示すように、チャック１に棒状の切削工具（エンドミル）２を装着し、効率よく切削屑を吸引できるようにする為に、エンドミル２の刃部３の左右近傍に噴射ノズル４と吸引ノズル５を対称的に設け、噴射ノズル４の噴射口６及び吸引ノズル５の吸引口７を刃部３の先端に向けてある。また、有害汚染物８の切削面９は、図面では軸線方向に直交するフラットな面であるが、実際は色々な形、例えばボルト頭等で凸凹している場合も想定されることから、切削面９に各ノズル４，５が干渉せずに所望の深さ切削できるように、噴射ノズル４と吸引ノズル５を刃部３の先端よりも僅かに根元側（図の上側）に配置してある。符号１０はヘッドで、切削工具２を回転させる主軸（図示せず）の回りを囲んでいる。
【００１８】
工作機械の第一例を使用する場合は、ガスとしての空気を噴射ノズル４から吹き付け、一方、吸引ノズル５から空気を吸引している状態で、切削工具２を回転して有害汚染物８を切削する。そうすると、切削屑は発生した直後に吸引ノズル５から吸い込まれて図示しないタンクに回収される。
【００１９】
工作機械の第二例は図２に示すように、ガスの吹き付け、吸引の仕方に特徴があるもので、ヘッド１０に二つの筒状のカバー１１，１２の一端部をそれぞれねじ込んで固定して、切削工具２の外側を二つのカバー１１，１２で二重に取り囲み、内側のカバー１１と切削工具２の間、並びに内外のカバー１１，１２の間にガス流通空間１３，１４をそれぞれ形成してある。切削深さを考慮して二つのカバー１１，１２の先端を刃部３の先端よりも短く（根元側に）設定し、有害汚染物８の切削面９との干渉を避けるために、ガス入口１５及びガス出口１６をカバーの先端よりも根元側に形成し、ガス入口１５に接続する供給管Ｋを、ガス入口１５と同じ位置かそれよりも根元側に延長し、ガス出口１６に接続する排出管Ｈも同様に延長してある。
【００２０】
また、切削箇所へのガスの流入効率を上げて冷却効果を高めるために、内側のカバー１１の先端を外側のカバー１２の先端よりも短く設定し、ガス入口１５を外側のカバー１２に設け、ガス出口１６を内側のカバー１１に設けてある。このようにすることで、外側カバー１２から入ったガスが下降して、内側カバー１１の先端と切削面９の隙間を経て、切削工具２の先端に向かい、その後、上昇して内側のカバー１１内から外部に排出されることになる。なお、第二例とは異なるが、一つのカバーで切削工具を取り囲む構造の場合であれば、ガス入口からカバー内に入ったガスが、下降して切削工具の先端に向かうことなく、ガス出口に向かって直進すると考えられるので、第二例のようにすれば冷却効果が高まると言える。また、ガスの吸引量をガスの供給量以上にすれば、外側のカバー１２の先端と切削面９の隙間からガスが外部に漏れ出る量を少なくできる。このようにすれば、常温の空気以外をガスとして用いる場合は、切削箇所へのガスの流入効率を向上できる。
【００２１】
上述した第二例を使用した場合には、二重のカバー１１，１２の中で切削工具２が回転して有害汚染物８を切削するので、切削屑が周囲に飛散するのを高い確率で防止できる。
【００２２】
工作機械の第三例は図３に示すように、第二例を前提としながら、ガスを供給する経路に特徴を持たせたもので、切削工具２の中心に軸線方向に沿ってガス供給路１７を形成し、切削工具２の先端から有害汚染物８に向かって一直線にガスを吹き付けると共に、切削工具２の先端部から周囲に放射状にガスを吹き付けるものである。また、チャック１にもガス供給路１７に通じる連絡路１８を形成し、チャック１に固定した管路１９を、内外のカバー１１，１２の抜穴２０，２１を通して外部に導いたものである。なお、チャック１には、管路１９との接続を確保しながら切削工具２と一緒に回転し、連絡路１８にガスを供給可能とするものが現存する。
【００２３】
工作機械の第三例を使用する場合は、ガスの供給箇所がカバー１１，１２の内部だけでなく、切削工具２の内部にもあるので、冷却効果が向上する。
【００２４】
本発明は上記した例に限定されない。例えば、切削工具２内にガスを送り込むには、チャック１、主軸に流路を連通して形成しても良い。
【００２５】
【発明の効果】
請求項１の発明は、ガスの吹き付けが切削箇所の近傍で行われるので、切削箇所が効率よく冷却されることになり、ダイオキシンが発生し難くなるし、切削時間が短縮する。また、ガスと切削屑の吸引が切削箇所の近傍で行われるので、切削屑の回収率が向上して、周囲への飛散が防止できる。
【００２６】
請求項２の発明は、カバーによって切削工具の周囲を覆うことから、切削屑の周囲への飛散が効果的に防止される。しかも、ガスが切削箇所に効率良く送られることから冷却効果が高まり、切削時間の短縮が図られる。
【００２７】
請求項３の発明は、軸線方向のガス供給路によって切削工具自体が冷却されることから、切削箇所の冷却効果が高まり、ダイオキシンが発生し難くなるし、切削時間の短縮も図られる。
【００２８】
請求項４の発明は、ガスに常温よりも冷たいものを用いることで、切削箇所の冷却効果が向上する。

BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a method for collecting scraps (such as transformers and capacitors containing PCB) contaminated with harmful substances that become dioxins by oxidation, that is, when cutting and disassembling harmful contaminants.
[0002]
[Prior art]
One means for disassembling a device containing PCB is cutting. Various measures have been taken to prevent the PCB from being oxidized to dioxins by the processing heat during cutting. Specifically, the cutting speed is slowed down, the atmosphere is inert gas, or the cooling gas is blown to perform cutting (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
JP 2003-302318 A (page 3)
[0004]
[Problems to be solved by the invention]
However, if the cutting speed is slowed down, it takes time and the efficiency becomes worse. In general cutting, cutting oil is used, but if cutting oil is used, the cutting oil is contaminated by the PCB and becomes a secondary contaminant. If it is scattered around, the contamination will increase. It is desirable to cut without using. When cutting without using cutting oil, the cutting location becomes hotter than using the cutting oil. Therefore, in order to prevent the generation of dioxins, it is necessary to further reduce the cutting speed, and the efficiency is greatly deteriorated.
[0005]
On the other hand, when cutting under an inert gas atmosphere or by blowing cooling gas, the cutting speed can be increased. However, if the cutting waste scatters to a place where the inert gas or cooling gas does not reach, it is oxidized by the processing heat. Dioxin may be generated.
[0006]
Furthermore, if the cutting waste is not collected, the cutting waste will adhere to the cut harmful contaminants, and when the harmful contaminants are subsequently cleaned with a cleaning device to remove the PCB, the cutting waste is collected on the filter or pump of the cleaning device. There is a risk of causing problems such as clogging.
[0007]
The present invention has been developed to improve the above-mentioned problems, and the basic problems to be solved are to improve the cutting speed, prevent the scattering of cutting waste, and collect the cutting waste.
[0008]
The inherent problem to be solved by the invention of claim 2 is to improve the cooling effect of the cutting portion and to improve the recovery rate of the cutting waste. The inherent problem to be solved by the invention of claim 3 is to improve the cooling effect of the cutting tool itself. The inherent problem to be solved by the invention of claim 4 is to improve the cooling effect of the cutting portion.
[0009]
[Means for Solving the Problems]
The invention according to claim 1 is characterized in that when harmful pollutants are cut, gas is blown in the vicinity of the rod-shaped cutting portion, and gas and cutting waste are sucked and collected in the vicinity of the cutting portion.
[0010]
In the vicinity, when gas is blown, it means that the gas hits the cutting location efficiently and the cooling effect by air cooling is sufficiently obtained. It means a distance that can be sucked and collected without being scattered.
[0011]
The gas may be any gas that cools the blade and harmful pollutants by its air-cooling action, and excludes those that may explode, such as hydrogen and oxygen. Specifically, an inert gas such as air, nitrogen gas, or argon can be exemplified, and if it is an inert gas, generation of dioxins due to cutting processing heat can be effectively prevented.
[0012]
Although cutting may be performed without covering the periphery of the cutting location, in order to increase the gas cooling effect and the cutting waste recovery rate, the outer side of the cutting tool is surrounded by a cylindrical cover as in the invention of claim 2. It is desirable to form a gas circulation space between the cutting tool and the cover, and to blow and suck the gas to the gas circulation space.
[0013]
One cover may be provided, or a plurality of covers may be provided at intervals.
[0014]
The gas spray may be performed only from around the cutting tool. However, as in the invention of claim 3, a gas supply path is formed in the axial direction of the cutting tool, and the gas is discharged from the tip of the cutting tool blade. Things can be used.
[0015]
The direction in which the gas is discharged from the blade tip is not particularly limited, and may be, for example, an axial direction or a direction intersecting the axial direction.
[0016]
The temperature of the gas is not particularly limited, but it is desirable to use a gas that is cooler than room temperature as in the invention of claim 4 in order to enhance the cooling effect.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the first example of a machine tool used for the method of collecting harmful contaminants according to the present invention is equipped with a bar-shaped cutting tool (end mill) 2 attached to a chuck 1 to efficiently suck the chips. In order to make it possible, the injection nozzle 4 and the suction nozzle 5 are provided symmetrically in the vicinity of the left and right of the blade portion 3 of the end mill 2, and the injection port 6 of the injection nozzle 4 and the suction port 7 of the suction nozzle 5 are provided on the blade portion 3. Towards the tip. In addition, the cutting surface 9 of the harmful contaminant 8 is a flat surface orthogonal to the axial direction in the drawing, but in actuality, it may be assumed that the cutting surface 9 is uneven in various shapes, such as bolt heads. 9, the injection nozzle 4 and the suction nozzle 5 are arranged slightly closer to the root side (upper side in the figure) than the tip of the blade 3 so that the nozzles 4 and 5 can cut to a desired depth without interference. . Reference numeral 10 denotes a head, which surrounds a spindle (not shown) that rotates the cutting tool 2.
[0018]
When using the first example of a machine tool, air as gas is blown from the injection nozzle 4 while air is sucked from the suction nozzle 5 to rotate the cutting tool 2 to remove harmful contaminants 8. To cut. Then, immediately after the cutting waste is generated, it is sucked from the suction nozzle 5 and collected in a tank (not shown).
[0019]
As shown in FIG. 2, the second example of the machine tool is characterized by the manner in which gas is blown and sucked. One end of two cylindrical covers 11 and 12 is screwed into the head 10 and fixed. The outer side of the cutting tool 2 is doubly surrounded by two covers 11 and 12, and gas flow spaces 13 and 14 are formed between the inner cover 11 and the cutting tool 2 and between the inner and outer covers 11 and 12, respectively. It is. In order to avoid the interference of the harmful contaminant 8 with the cutting surface 9 by setting the tips of the two covers 11 and 12 to be shorter (on the root side) than the tips of the blade portion 3 in consideration of the cutting depth, 15 and the gas outlet 16 are formed on the base side with respect to the front end of the cover, and the supply pipe K connected to the gas inlet 15 is extended to the same position as the gas inlet 15 or on the base side and connected to the gas outlet 16. The discharge pipe H is similarly extended.
[0020]
Further, in order to increase the gas inflow efficiency to the cutting location and enhance the cooling effect, the tip of the inner cover 11 is set shorter than the tip of the outer cover 12, and the gas inlet 15 is provided in the outer cover 12, A gas outlet 16 is provided in the inner cover 11. By doing in this way, the gas that has entered from the outer cover 12 descends, passes through the gap between the tip of the inner cover 11 and the cutting surface 9, toward the tip of the cutting tool 2, and then rises to the inner cover 11. It will be discharged from inside to outside. Note that, unlike the second example, in the case of a structure that surrounds the cutting tool with a single cover, the gas exited from the gas inlet into the cover without going down and heading toward the tip of the cutting tool. Therefore, it can be said that the cooling effect is enhanced by the second example. Further, if the gas suction amount is set to be equal to or greater than the gas supply amount, the amount of gas leaking out from the gap between the tip of the outer cover 12 and the cutting surface 9 can be reduced. If it does in this way, when using air other than normal temperature air as gas, the inflow efficiency of the gas to a cutting location can be improved.
[0021]
When the second example described above is used, the cutting tool 2 rotates in the double covers 11 and 12 to cut the harmful contaminant 8, so it is highly probable that the cutting waste will scatter around. Can be prevented.
[0022]
As shown in FIG. 3, the third example of the machine tool is characterized in that the gas supply path is characterized while assuming the second example, and the gas supply path along the axial direction in the center of the cutting tool 2. 17 is formed, and gas is blown in a straight line from the tip of the cutting tool 2 toward the harmful contaminant 8, and gas is blown radially from the tip of the cutting tool 2 to the periphery. Further, a communication path 18 that leads to the gas supply path 17 is also formed in the chuck 1, and a conduit 19 fixed to the chuck 1 is led to the outside through the through holes 20 and 21 of the inner and outer covers 11 and 12. Note that there is an existing chuck 1 that can rotate together with the cutting tool 2 while securing the connection with the pipe line 19 and supply gas to the communication path 18.
[0023]
When the third example of the machine tool is used, the cooling effect is improved because the gas supply point is not only inside the covers 11 and 12 but also inside the cutting tool 2.
[0024]
The present invention is not limited to the examples described above. For example, in order to send the gas into the cutting tool 2, a channel may be formed in communication with the chuck 1 and the main shaft.
[0025]
【The invention's effect】
In the first aspect of the invention, since the gas is blown in the vicinity of the cutting location, the cutting location is efficiently cooled, dioxins are hardly generated, and the cutting time is shortened. Moreover, since the suction of the gas and the cutting waste is performed in the vicinity of the cutting location, the recovery rate of the cutting waste is improved and scattering to the surroundings can be prevented.
[0026]
In the invention of claim 2, since the periphery of the cutting tool is covered by the cover, scattering of the cutting waste to the periphery is effectively prevented. In addition, since the gas is efficiently sent to the cutting location, the cooling effect is enhanced and the cutting time is shortened.
[0027]
In the invention of claim 3, since the cutting tool itself is cooled by the gas supply path in the axial direction, the cooling effect of the cutting portion is increased, dioxins are hardly generated, and the cutting time is shortened.
[0028]
In the invention of claim 4, the cooling effect of the cutting portion is improved by using a gas that is colder than room temperature.
