ようになっている。Conventionally, in a laser processing machine, as shown in the perspective view of FIG. Dust 3 generated from a workpiece set on a processing table 6 attached and partitioned on a movable horizontal processing table 9 is removed through a plurality of inward openings 13 bored at equal intervals in a rectangular duct surrounding the processing table 6. After passing through a dust collector duct 12, the dust is sucked into a large 111 machine 11.
しかしながら、このような装置には下記のような問題が
ある。However, such devices have the following problems.
（１）集塵機の吸い込む風量は、テーブル面積を開口面
積として決まるため非常に多くなり、そのため集塵機の
容９が大きくなり、床面積、コスｌ−，！’Ｊ音等の点
で必ずしも実用的ではない。(1) The amount of air sucked into the dust collector is very large because it is determined by the table area as the opening area, so the volume of the dust collector becomes large, and the floor area and cost l-,! 'It is not necessarily practical in terms of J sound etc.
（２）平板のワークがテーブル上面を覆った状態では、
ワーク下に吹きつけられた粉塵はテーブル内にこもるか
ら吸い込めるが、ワ−り上面に浮き上った粉塵は上方に
逃げ、完全には集塵できない。(2) When the flat workpiece covers the top of the table,
Dust blown under the workpiece is trapped inside the table and can be sucked in, but dust floating on the top of the workpiece escapes upward and cannot be completely collected.
（３）風量が多いためテーブルに組付ける配管径も太い
ものにしなければならず、テーブルＭ量が多くなり、ス
ペースも不利となり見映えも悪い。(3) Since the air volume is large, the diameter of the piping assembled to the table must be large, which increases the amount of table M, resulting in disadvantageous space and poor appearance.
（４） これを解決するための手段として、レーザー
加工機全体をアクリル等でカバーする場合は、集塵機は
小さくて済むが、材料扱い等のマテリアルハンドリング

実用性が低い。(4) As a means to solve this problem, if the entire laser processing machine is covered with acrylic, etc., the dust collector will be small, but it will cause problems such as poor material handling and environmental problems for the workers inside. It has low practicality due to its poor quality and cost.
本発明はこのような事情に鑑みて提案されたもので、小

特徴とする。To this end, the present invention provides a plurality of air nozzles that are arranged along the four circumferences of a laser processing table and form a three-dimensional air curtain that uses ejected air to shield the upper end opening of the table from outside air, and the three-dimensional air curtain. The present invention is characterized by comprising a dust collector having a dust suction port opening inside the table and sucking dust generated from the workpieces on the table.

口を入れることにより、とじ込めた粉塵を逃がすことな
く吸い込み、処理することができる。According to this type of device, even if the dust is light and flies upward, it is surrounded three-dimensionally by an air curtain and is contained within it, and by placing the dust collection port of the dust collector duct inside this, , the trapped dust can be sucked in and disposed of without escaping.

出させる。In the above figure, the same reference numbers as in FIG.
In order to form an air curtain 2 above the table that three-dimensionally surrounds the table opening and the dust collector suction port 5, the air nozzles on the long side opposite to the dust suction port are arranged at appropriate intervals on the inner circumference of the table. Air is ejected diagonally upward as shown by the arrow,
It also acts to push the dust 3 into the dust suction port 5. A dust collector 4 is disposed near the rear end of the processing table 6, and its dust suction port 5 opens into the space formed by the air curtain 2, and the sucked dust is processed with a filter or the like. Reference numeral 6 denotes a laser processing table, and a workpiece 6-1 is placed on a plurality of blade points 6-2 protruding from the table vertically and horizontally. Reference numeral 10 denotes an air pipe which introduces air supplied from an air source into the air nozzle 1 and blows it out.

より集塵機４に集塵される。At that time, in this device, the top surface of the table is shielded from the outside R1 by the air curtain, so the dust does not escape to the outside, but is trapped inside, and due to the bushing effect of the air and the suction of the dust collector 4. The dust is collected in the dust collector 4 due to the synergistic effect with the pull effect caused by the force.
粉塵は、タバコのけむり程度の軽いものが多いので、エ
アカーテンの風量も比較的少な（て、これをとじ込め、
かつ集塵機へと押し込むことができる。Since most of the dust is as light as cigarette smoke, the amount of air flow from the air curtain is relatively small.
and can be pushed into a dust collector.
このような装置によれば、下記の効果が奏せられる。 According to such a device, the following effects can be achieved.
（１） エアカーテンでテーブル開口部直上空間を包
囲するので、粉塵が外部に逃げない。(1) The air curtain surrounds the space directly above the table opening, preventing dust from escaping to the outside.
（２） とじ込めた粉塵をエアのブツシュ効果と集塵
機のプル効果で効率良く集塵することができる。(2) Trapped dust can be efficiently collected by the bushing effect of the air and the pull effect of the dust collector.
（３）従って、装置も簡単で集塵機の容量も小さくて済
