Description

本発明は、クリーナヘッドに関する。 The present invention relates to cleaner heads.

従来、図７又は図８に示すような断面形状のクリーナヘッドが公知である（特許文献１参照）。
即ち、断面矩形状の包囲外壁部51と、この包囲外壁部51の内部を、バキューム空間52とプレッシャ空間53と、バキューム空間52に区画形成する一対の区画内壁部54，54とを、一体に有する押出型材から作成されたクリーナヘッド本体55を、備えている。 Conventionally, a cleaner head having a cross-sectional shape as shown in FIG. 7 or 8 is known (see Patent Document 1).
That is, the enclosing outer wall portion 51 having a rectangular cross section, the vacuum space 52, the pressure space 53, and the pair of partitioned inner wall portions 54 that partition the interior of the enclosing outer wall portion 51 into the vacuum space 52, 54, are integrally formed. and a cleaner head body 55 made from an extruded profile with.

中央のプレッシャ空間53内の高圧エアーは、矢印56のように噴出されて、ワーク（被除塵面）57に当たって、直ちに矢印58，58のようにバキューム空間52に吸引される。
図７に示すように、ワーク（被除塵面）57に対向する一辺59を有するが、図８と図９に於て、この一辺59の拡大図を示し、一対の区画内壁部54の下端を連結する部位の中間には、微小間隙寸法εの吐出用スリット60が設けられている。さらに、一対の吸込用スリット61，61が一辺59に設けられている。 The high-pressure air in the central pressure space 53 is jetted as indicated by arrow 56, hits the workpiece (surface to be dust-removed) 57, and is immediately sucked into the vacuum space 52 as indicated by arrows 58,58.
As shown in FIG. 7, it has one side 59 facing a workpiece (surface to be dust-removed) 57. FIGS. An ejection slit 60 with a minute gap dimension ε is provided in the middle of the connecting parts. Furthermore, a pair of suction slits 61 , 61 are provided on one side 59 .

特許第４９４０３２３号公報Japanese Patent No. 4940323

ところで、吐出用スリット60の間隙寸法εは、吸込用スリット61，61の各間隙寸法よりも十分に小さく、この吐出用スリット60の微小間隙寸法εが規定値よりも僅かに大きい場合には、エアー噴出速度が小さくなり、安定した十分な除塵作用効果が得られない。逆に、この吐出用スリット60の微小間隙寸法εが規定値よりも僅かに小さい場合には、エアー噴出時の圧力損失が増加するので、エアー噴出速度が増加せず、十分な除塵効果が得られない。 By the way, the gap dimension ε of the discharge slit 60 is sufficiently smaller than the gap dimensions of the suction slits 61, 61, and when the minute gap dimension ε of the discharge slit 60 is slightly larger than the specified value, The air ejection speed becomes small, and a sufficient and stable dust removing effect cannot be obtained. Conversely, if the minute gap dimension ε of the ejection slit 60 is slightly smaller than the specified value, the pressure loss during air ejection increases, so the air ejection speed does not increase and a sufficient dust removal effect is obtained. can't

そこで、図８と図９に示したような、吐出用スリット60の間隙寸法εを増減調整するための間隙調整機構65が設けられていた。
この間隙調整機構65は、ネジ孔62，62付の帯板63と、各ネジ孔62に螺着されるボルト64，64と、一辺59の外部から座ぐり形成された大径座ぐり孔66と（内径Ｄ67の）中径孔67とを、備える。しかも、帯板63は、吐出用スリット60に連通すると共に浅い凹溝68を有すると共に、凹溝68とプレッシャ空間53とを連通する貫孔69を有している。 Therefore, as shown in FIGS. 8 and 9, a gap adjusting mechanism 65 for adjusting the gap size ε of the ejection slit 60 is provided.
This gap adjusting mechanism 65 includes a band plate 63 with screw holes 62, 62, bolts 64, 64 screwed into the respective screw holes 62, and a large-diameter counterbore 66 formed from the outside of one side 59. and a medium bore 67 (of inner diameter D 67 ). Moreover, the band plate 63 has a shallow groove 68 that communicates with the discharge slit 60 and has a through hole 69 that communicates the groove 68 with the pressure space 53 .

上記間隙調整機構65によって、吐出用スリット60の微小間隙寸法εを調整する方法を説明すると、以下の通りである。
即ち、図９に於て、下方（外部）から六角レンチ等の作業工具にて（多数本の）ボルト64を緩め、薄い帯片状の計測ゲージにて間隙寸法εを何度も計測しつつ、区画内壁部54，54が相互に接近（又は分離）するように（断面において）揺動変形させつつ、間隙寸法εを規定値に保持し、直ちにボルト64を締付けて、間隙寸法εを規定値に設定できる。 A method of adjusting the minute gap size ε of the discharge slit 60 by the gap adjusting mechanism 65 is as follows.
That is, in FIG. 9, the (multiple) bolts 64 are loosened from below (outside) with a working tool such as a hexagonal wrench, and the gap dimension ε is measured many times with a thin strip-shaped measurement gauge. , while oscillatingly deforming (in cross section) so that the partition inner wall portions 54, 54 approach (or separate) from each other, the gap dimension ε is held at a specified value, and the bolt 64 is immediately tightened to define the gap dimension ε. can be set to a value.

しかしながら、図８，図９をもって説明した間隙調整機構65による吐出用スリット60の微小間隙寸法εの調整作業は次のような欠点があった。
つまり、（ｉ）多数のボルト64の螺進・螺退の作業と、区画内壁部54，54を相互に接近・分離させて間隙寸法εを減少・増加させる作業とを同時又は交互に行うことは、熟練を要し、極めて難しい作業である点、（ii）一辺59の外部から前述の区画内壁部54，54を相互に接近させる作業は、微小な寸法の吸込用スリット61，61にバイス等を引掛ける必要があり、作業が難しいと共に、吸込用スリット61に傷を付ける虞れがある点、(iii) 印刷ローラ，延伸ローラ，プラスチックフィルム等の除塵作業中に、万一、ボルト64が緩んでくると、落下し易く、直ちに上記印刷ローラ等の被除塵面に接触して、損傷を与える重大事故の虞れがある点。
従来のクリーナヘッドの吐出用スリット60の間隙調整機構65には、上述したような欠点(ｉ)(ii)(iii) があった。 However, the operation of adjusting the minute gap dimension ε of the ejection slit 60 by the gap adjusting mechanism 65 described with reference to FIGS. 8 and 9 has the following drawbacks.
That is, (i) the work of screwing and unscrewing the large number of bolts 64 and the work of moving the partition inner wall portions 54, 54 closer to each other and separating from each other to decrease or increase the gap dimension ε are performed simultaneously or alternately. is an extremely difficult task requiring skill. (iii) In the event that the bolt 64 is removed during the dust removal work of the printing roller, stretching roller, plastic film, etc. If it becomes loose, it is likely to fall, and it may immediately come into contact with the surface to be dust-removed, such as the printing roller, resulting in serious damage.
The gap adjusting mechanism 65 of the discharge slit 60 of the conventional cleaner head has the above-described drawbacks (i), (ii), and (iii).

そこで、本発明は、包囲外壁部と、該包囲外壁部の内部空間をバキューム空間とプレッシャ空間とバキューム空間に区画形成する一対の区画内壁部とを、一体に有する押出型材から作成されたクリーナヘッド本体を備え；上記包囲外壁部は、横断面において、被除塵面に対向して配設される一辺を有し；一対の上記区画内壁部の間に形成された上記プレッシャ空間内の高圧エアーを噴出する微小間隙寸法の吐出用スリットを、上記一辺に開設したクリーナヘッドに於て；上記区画内壁部が、上記微小間隙寸法が増減するように揺動自在であって、上記一辺に直交状の一対の側壁部の各々の外部から回転操作して、押圧力と引張力を、上記区画内壁部に対して交互に付与し、上記区画内壁部を揺動させることにより上記微小間隙寸法を増減調整する押圧引張手段を、具備し；上記押圧引張手段は；一対の上記側壁部の各々の長手方向に沿って、所定ピッチをもって大径ネジ孔を配設し；さらに、一対の上記区画内壁部の長手方向に沿って、上記所定ピッチと同一ピッチをもって、かつ、上記大径ネジ孔と同一軸心上に小径ネジ孔を配設し；押圧ボルトは上記大径ネジ孔に適合する大径雄ネジを有すると共に、上記小径ネジ孔に遊嵌状に挿入されて押圧ボルトの先端振れを防止する位置決め用小径突部が、押圧ボルトの先端面から突設され；引張ボルトは、先端に上記小径ネジ孔に適合する小径雄ネジを有すると共に、基端には、上記大径ネジ孔に遊挿自在な中径雄ネジを有し、さらに、該中径雄ネジが上記側壁部から突出した部位に螺合する引張用調整ナットを設け；一対の上記側壁部の各々の長手方向に沿って、上記所定ピッチをもって、上記押圧ボルトと引張ボルトを、交互に配設した。 Accordingly, the present invention provides a cleaner head made of an extruded material integrally having an enclosing outer wall and a pair of partitioned inner walls that partition the inner space of the enclosing outer wall into a vacuum space, a pressure space, and a vacuum space. a main body; the enclosing outer wall has one side facing the surface to be dust-removed in cross section; high pressure air in the pressure space formed between the pair of partition inner walls In the cleaner head in which a discharge slit having a minute gap dimension for jetting is formed on one side of the cleaner head; By rotating each of the pair of side wall portions from the outside, pressing force and tensile force are alternately applied to the inner wall portion of the partition, and the inner wall portion of the partition is oscillated, thereby adjusting the size of the minute gap. The pressing and pulling means includes large-diameter screw holes arranged at a predetermined pitch along the longitudinal direction of each of the pair of side wall portions; and the pair of partition inner wall portions. A small-diameter screw hole is arranged along the longitudinal direction at the same pitch as the predetermined pitch and on the same axis as the large-diameter screw hole; and a small-diameter positioning projection that is loosely inserted into the small-diameter screw hole to prevent tip deflection of the pressing bolt, protruding from the tip surface of the pressing bolt; It has a small-diameter male screw that fits into the screw hole, and has a medium-diameter male screw at the proximal end that can be loosely inserted into the large-diameter screw hole, and the medium-diameter male screw protrudes from the side wall portion.

このクリーナヘッド本体５は、図２（Ｃ）に、その一部を斜視図をもって示すように、比較的長手方向寸法が大きい長尺体である。即ち、外観は長尺の角筒であるといえる。また、図２（Ｃ）に示すように、クリーナヘッド本体５の左右各端の開口部は、矩形板６にて閉鎖され、一方の矩形板６には、高圧エアー供給管７と、エアー吸出管８，８が付設されている。本発明の説明に於て、クリーナヘッド本体５とは、矩形板６や高圧エアー供給管７・エアー吸出管８，８等の付属部材を除いた長尺体を指すものと定義する。 The cleaner head main body 5 is an elongated body having a relatively large longitudinal dimension, as shown in a perspective view of part of it in FIG. 2(C). That is, it can be said that the outer appearance is a long rectangular tube. Further, as shown in FIG. 2(C), the openings at the left and right ends of the cleaner head body 5 are closed by rectangular plates 6. On one of the rectangular plates 6, a high-pressure air supply pipe 7 and an air suction pipe 7 are provided. Pipes 8, 8 are attached. In the description of the present invention, the cleaner head body 5 is defined as a long body excluding attached members such as the rectangular plate 6, the high-pressure air supply pipe 7, the air suction pipes 8 and 8, and the like.

そして、上記包囲外壁部１は、横断面において、被除塵面９に対向して（平行状に）配設される一辺１Ａを有している。
一対の区画内壁部３，３の間に形成されたプレッシャ空間15内の高圧エアーを噴出する微小間隙寸法εの吐出用スリット２が、上記一辺１Ａの中央位置に開設されている。

A discharge slit 2 having a minute gap dimension ε for discharging high-pressure air in a pressure space 15 formed between a pair of partition inner wall portions 3, 3 is opened at the center position of the one side 1A.
A pressing force F 1 and a tensile force F 2 are applied to the partition inner wall portion 3 by rotating from the outside 11 of each of the side wall portions 1B (a pair of left and right) perpendicular to the side 1A. , a pressing/pulling means Y for increasing or decreasing the minute gap dimension ε.

図１及び図２に於ては、この押圧引張手段Ｙを構成している部材の大半は図示省略しており、クリーナヘッド本体５のみを主として示しているのであるが、一点鎖線12は、押圧引張手段Ｙが配設される高さ位置及び配設方向を示している。
具体的には、この押圧引張手段Ｙは、一対の側壁部１Ｂ，１Ｂの各々の長手方向に沿って、所定ピッチＰ0 （図２（Ｃ）参照）をもって配設した押圧ボルト21（図３参照）と引張ボルト22（図４参照）を、備えている。 In FIGS. 1 and 2, most of the members constituting the pressing/pulling means Y are omitted, and only the cleaner head main body 5 is mainly shown. The height position and arrangement direction of the pulling means Y are shown.
Specifically, this pressing/pulling means Y includes pressing bolts 21 (see FIG. 3) arranged at a predetermined pitch P 0 (see FIG. 2(C)) along the longitudinal direction of each of the pair of side wall portions 1B, 1B. ) and a tension bolt 22 (see FIG. 4).

さらに、詳しく押圧引張手段Ｙについて説明すると、図１～図４に示すように、一対の側壁部１Ｂ，１Ｂの各々の長手方向に沿って、所定ピッチＰ0 をもって大径ネジ孔13を配設する。さらに、一対の上記区画内壁部３，３の長手方向に沿って、上記所定ピッチＰ0 と同一ピッチをもって、小径ネジ孔14を配設する。 1 to 4, large-diameter screw holes 13 are arranged at a predetermined pitch P0 along the longitudinal direction of each of the pair of side wall portions 1B, 1B. do. Further, small-diameter screw holes 14 are provided along the longitudinal direction of the pair of partition inner wall portions 3, 3 with the same pitch as the predetermined pitch P0.

しかも、この小径ネジ孔14の軸心と大径ネジ孔13の軸心は、同一軸心とする。言い換えると、図２（Ａ）に示す如く、大径ネジ孔13と同一軸心（一点鎖線12）上に小径ネジ孔14を配設する。
つまり、図２（Ａ）に示した側壁部１Ｂに直交する方向から目視すれば、図２（Ｂ）に示すように、大径ネジ孔13の内部に、小径ネジ孔14が、（同心状に）見える。 Moreover, the axis of the small-diameter screw hole 14 and the axis of the large-diameter screw hole 13 are coaxial. In other words, as shown in FIG. 2A, the small-diameter screw hole 14 is arranged on the same axis (chain line 12) as the large-diameter screw hole 13. As shown in FIG.
That is, when viewed from the direction orthogonal to the side wall portion 1B shown in FIG. 2A, as shown in FIG. ) visible.

そして、図３に示すように、押圧ボルト21は、側壁部１Ｂの大径ネジ孔13に適合（螺合）する大径雄ネジ21Ａを有する。さらに、押圧ボルト21の先端面21Ｂから位置決め用短寸小径突部21Ｃが突設され、この小径突部21Ｃは、図３（Ｃ）に示すように、小径ネジ孔14に遊嵌状に挿入されて、押圧ボルト21の先端振れを防止する。
また、図３に示すように、ナット27を付設するのが望ましい。そして、押圧ボルト21は、その外端に六角孔付頭部21Ｅを有する（なお、六角形頭部とすることも可能である。） As shown in FIG. 3, the pressing bolt 21 has a large-diameter male screw 21A that fits (screws) into the large-diameter screw hole 13 of the side wall portion 1B. Further, a short small-diameter projection 21C for positioning is projected from the tip surface 21B of the pressing bolt 21, and this small-diameter projection 21C is loosely fitted into the small-diameter screw hole 14 as shown in FIG. 3(C). and prevents the tip of the pressing bolt 21 from wobbling.
Also, as shown in FIG. 3, a nut 27 is preferably provided. The pressing bolt 21 has a hexagonal hole head 21E at its outer end (a hexagonal head is also possible).

また、図４に示すように、引張ボルト22は、先端に、区画内壁部３の小径ネジ孔14に適合（螺合）する小径雄ネジ22Ａを有する。さらに、引張ボルト22の基端23には、中径雄ネジ24を有し、この中径雄ネジ24は、側壁部１Ｂの大径ネジ孔13に遊挿自在に、ネジ外径が設定されている（図４（Ｂ）参照）。 Moreover, as shown in FIG. 4, the tension bolt 22 has a small-diameter male screw 22A at its tip that fits (screws) into the small-diameter screw hole 14 of the compartment inner wall portion 3 . Further, the base end 23 of the tension bolt 22 has a medium-diameter male screw 24, and the medium-diameter male screw 24 has an outer diameter set so that it can be loosely inserted into the large-diameter screw hole 13 of the side wall portion 1B. (See FIG. 4B).

このような形状と構成の押圧ボルト21と引張ボルト22を、交互に、側壁部１Ｂの長手方向に沿って、一直線状に、配設されている。このようにして、図２（Ｃ）に示した如く、側壁部１Ｂの外面の長手方向に沿って、所定ピッチＰ0 をもって、押圧力Ｆ1 と引張力Ｆ2 を交互に付与し、区画内壁部３を揺動させることにより（図３又は図４の矢印Ｍ3 参照）、吐出用スリット２の微小間隙寸法εを調整することができる。 The medium-diameter male screw 24 of the tension bolt 22 has a tension adjusting nut 25 screwed onto a portion 24E projecting from the side wall portion 1B. Further, the outer end of the tension bolt 22 is formed with a slit 26 into which a rotary torque application tool such as a flathead screwdriver is inserted.
The pressing bolts 21 and tension bolts 22 having such a shape and configuration are alternately arranged in a straight line along the longitudinal direction of the side wall portion 1B. In this way, as shown in FIG. 2C, along the longitudinal direction of the outer surface of the side wall portion 1B , the pressing force F1 and the tensile force F2 are alternately applied with a predetermined pitch P0, thereby By swinging the portion 3 (see arrow M3 in FIG. 3 or 4), the minute gap dimension ε of the discharge slit 2 can be adjusted.

ところで、上記大径ネジ13及び大径雄ネジ21ＡをＭ６とし、中径雄ネジ24をＭ４とし、上記小ネジ孔14及び小径雄ネジ22ＡをＭ３とし、突部21Ｃの外径寸法を２．６ｍｍ等とするのが、望ましい。
このような寸法に設定すれば、寸法と形状と機能が大幅に相違した、押圧ボルト21及びその付属部品と、引張ボルト22及びその付属部品を、全く同じ寸法と形状の大径ネジ孔13・小径ネジ孔14に対して、使用可能である。 By the way, the large-diameter screw 13 and large-diameter male screw 21A are M6, the medium-diameter male screw 24 is M4, the small screw hole 14 and small-diameter male screw 22A are M3, and the outer diameter of the projection 21C is 2.6 mm. It is desirable to
If these dimensions are set, the pressure bolt 21 and its attached parts, and the tension bolt 22 and its attached parts, which are greatly different in size, shape and function, can be attached to the large-diameter screw holes 13 and 13 of exactly the same size and shape. It can be used for small-diameter screw holes 14 .

次に、図５，図６に示す他の実施形態について、以下説明する。
クリーナヘッド本体５の基本的形状と構造は、図１～図４の既説のものと同様である。即ち、図５と図６に示すように、包囲外壁部１と、該包囲外壁部１の内部空間１Ｍをバキューム空間10とプレッシャ空間15とバキューム空間10に区画形成する一対の区画内壁部３，３とを、一体に有する押出型材から作成されたクリーナヘッド本体５を備え、上記包囲外壁部１は、横断面において、被除塵面９に対向して配設される一辺１Ａを有し、一対の上記区画内壁部３，３の間に形成された上記プレッシャ空間15内の高圧エアーを噴出する微小間隙寸法εの吐出用スリット２を、上記一辺１Ａに開設した構成である。 Next, another embodiment shown in FIGS. 5 and 6 will be described below.
The basic shape and structure of the cleaner head body 5 are the same as those already described with reference to FIGS. That is, as shown in FIGS. 5 and 6, the enclosing outer wall 1 and a pair of partitioned inner walls 3 that partition the inner space 1M of the enclosing outer wall 1 into a vacuum space 10, a pressure space 15, and a vacuum space 10. 3, and the enclosing outer wall portion 1 has a side 1A arranged opposite to the surface 9 to be dust-removed in a cross section, and a pair of A discharge slit 2 having a very small gap dimension ε for discharging high-pressure air in the pressure space 15 formed between the partition inner walls 3, 3 is opened on the one side 1A.

しかしながら、以下の構成（形状・構造）が相違する。つまり、一辺１Ａに直交状の一対の側壁部１Ｂ，１Ｂには、長手方向に所定ピッチにて、押圧規制ボルト30が、複数本、配設される。
即ち、前述の実施形態（図１～図４参照）では、押圧ボルト21と引張ボルト22の２種類のボルトが使用されていたのに対し、図５，図６に示した他の実施形態では、押圧規制ボルト30のみが、複数本、図５，図６における紙面と直交方向───クリーナヘッド本体５の長手方向───に配設される。 However, the following configurations (shapes and structures) are different. That is, a plurality of pressure regulation bolts 30 are arranged at a predetermined pitch in the longitudinal direction on the pair of side wall portions 1B, 1B which are perpendicular to the side 1A.
That is, in the above-described embodiment (see FIGS. 1 to 4), two types of bolts, the pressure bolt 21 and the tension bolt 22, are used, whereas in the other embodiments shown in FIGS. , and only a plurality of pressure regulating bolts 30 are arranged in a direction orthogonal to the plane of FIGS.

そして、プレッシャ空間15の圧力が零の状態（大気圧状態）では、図６（Ａ）に示す如く、吐出用スリット２の間隙寸法ε′が、正規寸法よりも小さい場合がある。そこで、押圧規制ボルト30の先端面30Ａと区画内壁部３との間に、所定の小間隙ΔＧを設ける。 When the pressure in the pressure space 15 is zero (atmospheric pressure), the gap dimension ε' of the discharge slit 2 may be smaller than the normal dimension, as shown in FIG. 6(A). Therefore, a predetermined small gap ΔG is provided between the tip end surface 30A of the pressure regulation bolt 30 and the partition inner wall portion 3. As shown in FIG.

その後、プレッシャ空間15内の圧力Ｐ15を所定値まで上昇させた所定加圧状態下で、押圧規制ボルト30の先端面30Ａが、図６（Ｂ）に示す如く、区画内壁部３に当接するように、側壁部１Ｂの外部11から、押圧規制ボルト30を螺進・螺退し、吐出用スリット２の微小間隙寸法εを増減調整する構成である。
なお、本クリーナヘッドが除塵を必要とする設備に使用される際、プレッシャ空間15に供給（使用）されるエアー圧力と同じ値に、（図６（Ｂ）にて説明した）圧力Ｐ15を設定するのが、望ましい。 After that, under a predetermined pressurized state in which the pressure P15 in the pressure space 15 is increased to a predetermined value, the tip end face 30A of the pressure regulating bolt 30 contacts the partition inner wall portion 3 as shown in FIG. 6(B). As shown, the pressure regulation bolt 30 is screwed in and out from the outside 11 of the side wall portion 1B to increase or decrease the minute gap dimension ε of the ejection slit 2. As shown in FIG.
When this cleaner head is used in equipment that requires dust removal, the pressure P15 (explained in FIG. 6B) is set to the same value as the air pressure supplied (used) to the pressure space 15 . It is desirable to set

なお、図１～図４、又は、図５，図６に示した各実施形態において、吐出用スリット２の微小間隙寸法εを、スリットゲージ等の精密測定器具をもって、計測しつつ、ボルト21，22，30を螺進・螺退させる作業を、正確かつ容易・迅速に行うために、（図示省略したが）図１～図４、図５，図６とは天地逆に、床面等に設置して、行うのが望ましい。
また、エアを吸込む吸入スリット４の間隙寸法は、吐出用スリット２の間隙寸法εよりも、十分に大であるため、本発明に於て、微小間隙寸法εの調整変化量による、吸入スリット４からの吸込エアー流量の変化は微小である。 1 to 4 or FIGS. 5 and 6, the minute gap dimension ε of the discharge slit 2 is measured with a precision measuring instrument such as a slit gauge, and the bolt 21, 1 to 4, 5, and 6 are turned upside down (although not shown) on the floor, etc., in order to perform the work of screwing and screwing 22 and 30 accurately, easily, and quickly. It is desirable to set it up and do it.
In addition, since the gap dimension of the suction slit 4 for sucking air is sufficiently larger than the gap dimension ε of the ejection slit 2, in the present invention, the suction slit 4 The change in the intake air flow rate from the is very small.

なお、本発明は上述の実施形態に限らず、設計変更自由であって、各区画内壁部３が、側壁部１Ｂから一辺１Ａに連結状な場合を図示したが、これを、上壁部１Ｃから一辺１Ａに連結状とすることも自由である。 In addition, the present invention is not limited to the above-described embodiment, and the design can be changed freely, and the case where each compartment inner wall portion 3 is connected to one side 1A from the side wall portion 1B is illustrated. It is also free to form a connection from one side 1A.

本発明は、以上詳述したように、包囲外壁部１と、該包囲外壁部１の内部空間１Ｍをバキューム空間10とプレッシャ空間15とバキューム空間10に区画形成する一対の区画内壁部３，３とを、一体に有する押出型材から作成されたクリーナヘッド本体５を備え；上記包囲外壁部１は、横断面において、被除塵面９に対向して配設される一辺１Ａを有し；一対の上記区画内壁部３，３の間に形成された上記プレッシャ空間15内の高圧エアーを噴出する微小間隙寸法εの吐出用スリット２を、上記一辺１Ａに開設したクリーナヘッドに於て；上記一辺１Ａに直交状の一対の側壁部１Ｂ，１Ｂの各々の外部11から回転操作して、押圧力Ｆ1 ・引張力Ｆ2 を、上記区画内壁部３，３に対して付与し、上記微小間隙寸法εを増減調整する押圧引張手段Ｙを、具備する構成であるので、側壁部１Ｂの外部11（の広い作業空間）から容易に押圧力Ｆ1 ・引張力Ｆ2 を順次付与しつつ、容易かつ迅速に、正確な微小間隙寸法εの調整を行うことができる。また、側壁部１Ｂ，１Ｂに直接的に外力を付与する構造であるので、スムーズかつ容易に、微小間隙寸法εを増減調整できる。 As described in detail above, the present invention comprises an enclosing outer wall 1 and a pair of partitioned inner walls 3, 3 which partition the inner space 1M of the enclosing outer wall 1 into a vacuum space 10, a pressure space 15 and a vacuum space 10. and a cleaner head body 5 made of an extruded material integrally having a; A cleaner head in which a discharge slit 2 having a minute gap dimension ε for jetting high-pressure air in the pressure space 15 formed between the partition inner walls 3, 3 is formed on the side 1A; are rotated from the outside 11 of each of the pair of side wall portions 1B, 1B perpendicular to each other to apply a pressing force F 1 and a tensile force F 2 to the partition inner wall portions 3, 3, and the minute gap dimension Since the structure is provided with the pressing and pulling means Y for increasing or decreasing ε, the pressing force F 1 and the pulling force F 2 can be easily applied from (the wide work space of) the outside 11 of the side wall portion 1B in order and easily and easily. It is possible to quickly and accurately adjust the minute gap dimension ε. Further, since the structure is such that an external force is applied directly to the side wall portions 1B, 1B, it is possible to increase or decrease the minute gap dimension ε smoothly and easily.

また、上記押圧引張手段Ｙは、一対の上記側壁部１Ｂ，１Ｂの各々の長手方向に沿って、所定ピッチをもって、押圧ボルト21と引張ボルト22を、交互に配設している構成であるので、間隙寸法εが過大であれば、押圧ボルト21を螺進させることで簡単に微妙な減少調整を行い得る。逆に、間隙寸法εが過小であれば、引張ボルト22を回転させて、簡単に微妙な増加調整を行い得る。 Further, the pressing and pulling means Y is constructed by alternately arranging the pressing bolts 21 and the tension bolts 22 with a predetermined pitch along the longitudinal direction of each of the pair of side wall portions 1B, 1B. If the gap dimension ε is excessively large, the pressing bolt 21 can be screwed to easily and finely adjust the clearance. Conversely, if the gap dimension ε is too small, the tension bolt 22 can be rotated to easily make fine adjustments.

また、上記押圧引張手段Ｙは；一対の上記側壁部１Ｂ，１Ｂの各々の長手方向に沿って、上記所定ピッチＰ0 をもって大径ネジ孔13を配設し；さらに、一対の上記区画内壁部３，３の長手方向に沿って、所定ピッチＰ0 と同一ピッチをもって、かつ、上記大径ネジ孔13と同一軸心上に小径ネジ孔14を配設し；押圧ボルト21は上記大径ネジ孔13に適合する大径雄ネジ21Ａを有し；引張ボルト22は、先端に上記小径ネジ孔14に適合する小径雄ネジ22Ａを有すると共に、基端23には、上記大径ネジ孔13に遊挿自在な中径雄ネジ24を有し、該中径雄ネジ24が上記側壁部１Ｂから突出した部位24Ｅに螺合する引張用調整ナット25を有し；一対の上記側壁部１Ｂ，１Ｂの各々の長手方向に沿って、上記押圧ボルト21と引張ボルト22を、交互に配設するよう構成したので、側壁部１Ｂには全く同じ大径ネジ孔13を所定ピッチで列設すれば良いので、加工作業が容易である。かつ、区画内壁部３には全く同じ小径ネジ孔14を所定ピッチで列設すれば良く、加工作業が容易である。そして、同一軸心上の大径ネジ孔13と小径ネジ孔14が一セットとして、列設された状態下で、側壁部１Ｂの長手方向に、押圧ボルト21と引張ボルト22を、交互に螺合して配設できる構造であるので、長い寸法を有する吐出用スリット２の長手方向の各位置にて、高精度の間隙寸法εを増減する調整作業を、熟練を要さずに容易かつ正確に、行うことを可能とした。 The pressing and pulling means Y has large-diameter screw holes 13 arranged at the predetermined pitch P0 along the longitudinal direction of each of the pair of side wall portions 1B and 1B; A small diameter screw hole 14 is arranged along the longitudinal direction of 3, 3 with the same pitch as the predetermined pitch P0 and on the same axis as the large diameter screw hole 13; The tension bolt 22 has a large-diameter male screw 21A that fits in the hole 13; It has an insertable medium-diameter male screw 24, and has an adjusting nut 25 for tension screwing into a portion 24E where the medium-diameter male screw 24 protrudes from the side wall portion 1B; Since the pressing bolts 21 and the tension bolts 22 are arranged alternately along the longitudinal direction, the same large-diameter screw holes 13 may be arranged in rows at a predetermined pitch in the side wall portion 1B. Easy to work with. In addition, it suffices to line up exactly the same small-diameter screw holes 14 on the partition inner wall portion 3 at a predetermined pitch, which facilitates the processing work. Then, in a state in which the large-diameter screw hole 13 and the small-diameter screw hole 14 on the same axis are aligned as a set, a pressing bolt 21 and a tension bolt 22 are alternately screwed in the longitudinal direction of the side wall portion 1B. Since it is a structure that can be arranged together, it is possible to easily and accurately adjust the high-precision gap dimension ε at each position in the longitudinal direction of the ejection slit 2 having a long dimension without requiring skill. and made it possible to do so.

また、包囲外壁部１と、該包囲外壁部１の内部空間１Ｍをバキューム空間10とプレッシャ空間15とバキューム空間10に区画形成する一対の区画内壁部３，３とを、一体に有する押出型材から作成されたクリーナヘッド本体５を備え；上記包囲外壁部１は、横断面において、被除塵面９に対向して配設される一辺１Ａを有し；一対の上記区画内壁部３，３の間に形成された上記プレッシャ空間15内の高圧エアーを噴出する微小間隙寸法εの吐出用スリット２を、上記一辺１Ａに開設したクリーナヘッドに於て；上記一辺１Ａに対し、横断面直交状の一対の側壁部１Ｂ，１Ｂは、各々、長手方向に沿って所定ピッチＰ0 にて押圧規制ボルト30が、配設され；上記プレッシャ空間15が、所定加圧状態下で、上記押圧規制ボルト30の先端面30Ａが上記区画内壁部３に当接するように、上記側壁部１Ｂの外部11から上記押圧規制ボルト30を螺進・螺退させ；上記微小間隙寸法εを増減調整するよう構成したので、引張ボルトが省略できて、押圧規制ボルト30のみで済み、構成部品の簡素化を図り得る。しかも、プレッシャ空間15の加圧状態下の圧力Ｐ15を、実際に稼動する設備に於て使用されるエアー圧力と、同一に設定することも可能であり、そのような同一圧力にて調整した間隙寸法εは、実際に稼動したときに、最適のエアー噴出速度をもって確実に優れた除塵性能を発揮する。 An extruded shape material integrally comprising the enclosing outer wall portion 1 and a pair of partitioned inner wall portions 3, 3 that partition the inner space 1M of the enclosing outer wall portion 1 into a vacuum space 10, a pressure space 15, and a vacuum space 10. The enclosing outer wall 1 has a side 1A disposed facing the surface 9 to be dust-removed in cross section; In a cleaner head having a discharge slit 2 with a minute gap dimension ε for discharging high-pressure air in the pressure space 15 formed in the above-mentioned one side 1A; The side wall portions 1B, 1B of each are provided with pressure regulating bolts 30 at a predetermined pitch P0 along the longitudinal direction; The pressure regulating bolt 30 is screwed in and out from the outside 11 of the side wall portion 1B so that the tip surface 30A abuts on the partition inner wall portion 3; The tension bolt can be omitted, and only the pressure regulation bolt 30 is required, thereby simplifying the components. Moreover, it is possible to set the pressure P15 under the pressurized state of the pressure space 15 to be the same as the air pressure used in the equipment that actually operates, and the adjustment was made at such the same pressure. The gap dimension ε ensures excellent dust removal performance with the optimum air ejection speed during actual operation.
