けるエア６を吸引し、保持具13によって挟持されネジ３
を中空部2Aに取り込み、吸着する。As shown in FIG. 4 (a), the screw 3 is held by a holder 13 composed of a lever 10 which is rotated around a pin 12 and a spring 11 which is stretched between the lever 10, and the bit 1
, The suction pipe 2 provided in the hollow portion 2A is lowered in the direction of arrow Z as shown in (b), the bit 1 is rotationally driven as shown by arrow E, and at the same time, the hollow portion 2A of the suction pipe 2 is moved. The air 3 is sucked, and is clamped by the holder 13 so that the screw 3
Is taken into the hollow portion 2A and adsorbed.
この場合、ネジ３の頭部3Aに設けられた溝穴3Bは、ビッ
ト１の先端部1Aに挿入が行われるように形成されてい
た。In this case, the slot 3B provided in the head 3A of the screw 3 was formed so that the tip 1A of the bit 1 could be inserted.
そこで、このように中空部2Aにネジ３が吸着されること
でレバー10が矢印Ａのように開き、（ｃ）に示すよう
に、吸着パイプ２を被締付部材４の所定個所に位置させ
るように降下させる。Then, the lever 10 is opened as shown by the arrow A by thus sucking the screw 3 in the hollow portion 2A, and the suction pipe 2 is positioned at a predetermined position of the tightened member 4 as shown in (c). To descend.
この場合、被締付部材４が、例えば、バカ穴4A−１を有

4A−１に挿入させ、ネジ３の締め付けが行われる。In this case, if the member 4 to be tightened is one that is screwed by stacking the member 4-1 having the stupid hole 4A-1 and the member 4-2 having the screw hole 4A-2, for example, (D)
After the suction pipe 2 descends, bit 1
Protruding along the hollow 2A, and the tip 3C of the screw 3
4A-1 is inserted and the screw 3 is tightened.
しかし、このような吸着パイプ２にネジ３を中空部2Aに

させる問題を有していた。When such a drop occurs, as shown in (e), the screw 3
There was a problem that the slot 3B of the head 3A and the tip 1A of the bit 1 were misaligned, and the head 3A of the screw 3 was damaged when the screw 3 was reinserted.
そこで、本発明では、ネジの先端を突出させる際、ネジ
の脱落が生じることのないようにすることを目的とす
る。Therefore, an object of the present invention is to prevent the screw from falling off when the tip of the screw is projected.
第１図は本発明の原理説明図である。 FIG. 1 is an explanatory view of the principle of the present invention.
第１図に示すように、エア６の吸引によってネジ３の頭
部3Aを保持する凹部5Aを有し、吸着パイプ２の中空部2A
をスライドする外形Ｄに形成された金具５がビット１の
先端部1Aに係止されるように構成する。As shown in FIG. 1, the hollow portion 2A of the suction pipe 2 has a recess 5A for holding the head 3A of the screw 3 by suction of air 6.
The metal fitting 5 formed in the outer shape D that slides is configured to be locked to the tip portion 1A of the bit 1.
このように構成することによって前述の課題は解決され
る。With this configuration, the above-mentioned problems can be solved.
即ち、ビット１の先端部1Aにエアの吸引によってネジ３
の頭部3Aを保持する凹部5Aを有する金具５を係止し、ビ
ット１が吸着パイプ２の中空部2Aを降下し、ネジ３を中
空部2Aから突出させる時、ネジ３の突出が金具５が吸着
パイプ２から突出することで突出が行われるようにした
ものである。That is, the screw 3 is applied to the tip 1A of the bit 1 by sucking air.
When the metal fitting 5 having the recessed portion 5A for holding the head 3A is locked, the bit 1 descends the hollow portion 2A of the suction pipe 2, and the screw 3 is projected from the hollow portion 2A, the projection of the screw 3 is the metal fitting 5 The projection is performed by projecting from the suction pipe 2.
したがって、吸着パイプ２の降下が被締付部材４より離

にネジ３の頭部3Aが保持された状態となり、従来のよう
な脱落がなく、ネジ３の先端3Cを被締付部材４の穴4Aに
確実に螺着させることが行える。Therefore, even if the suction pipe 2 is lowered to a position apart from the tightened member 4, the protrusion of the screw 3 is caused by the recess 5A of the metal fitting 5.
Since the head portion 3A of the screw 3 is held, the tip 3C of the screw 3 can be securely screwed into the hole 4A of the tightened member 4 without dropping off as in the conventional case.

イプ２の中空部2Aに吸着させるようにしたものである。As shown in FIG. 1 (a), the hollow portion 2A of the adsorption pipe 2
A metal fitting 5 having a recess 5A is formed so as to be engaged with the tip 1A of the bit 1 provided on the lever 10, and a lever 10 rotated around a pin 12 and a spring 11 stretched around the lever 10 are provided. The screw 3 held by the holding metal fitting 13 is made to adsorb to the hollow portion 2A of the adsorption pipe 2.
この場合のネジ３の吸着は、（ｂ）に示すように、ビッ
ト１を矢印Ｅのように回転させると共に、中空部2Aのエ
ア６を吸引することで行われる。In this case, the suction of the screw 3 is performed by rotating the bit 1 as shown by arrow E and sucking the air 6 in the hollow portion 2A as shown in (b).
また、金具５は、第３図（ａ）に示すように、中空部2A
に挿脱可能な直径Ｄの筒状に形成され、中央にはビット

は通気穴5Bが、端面にはネジ３の頭部3Aが挿入される凹
部5Aがそれぞれ設けられ、固定ピン5Dの挿入によって先
端部1Aに係止されるように形成されている。Further, the metal fitting 5 has a hollow portion 2A as shown in FIG. 3 (a).
It is formed into a cylindrical shape with a diameter D that can be inserted and removed, and has a through hole 5C for inserting the tip 1A of the bit 1 in the center, a vent hole 5B on the outer periphery of the through hole 5C, and the head of the screw 3 on the end face. Recesses 5A into which the parts 3A are inserted are respectively provided, and are formed so as to be locked to the tip part 1A by inserting the fixing pin 5D.
そこで、中空部2Aのエア６の吸引は、通気穴5Bを通して
行われることになり、ネジ３の頭部3Aが金具５の凹部5A
に取り込まれ、先端部1Aが頭部3Aの溝穴3Bに挿入され、
金具５によってネジ３が保持される状態となる。Therefore, the air 6 in the hollow portion 2A is sucked through the vent hole 5B, and the head 3A of the screw 3 is recessed in the metal fitting 5A.
, The tip 1A is inserted into the slot 3B of the head 3A,
The screw 3 is held by the metal fitting 5.
したがって、吸着パイプ２を矢印Ｚ方向に降下させ、
（ｃ）に示すように、被締付部材４の直上にネジ３を位
置させた時、被締付部材４に固着された部品８が障害と
なった場合は、ビット１を更に降下させても、金具５に
よってネジ３が保持された状態で突出が行われることに
なり、ネジ３が脱落することがない。Therefore, the suction pipe 2 is lowered in the arrow Z direction,
As shown in (c), when the screw 3 is positioned immediately above the member to be fastened 4 and the component 8 fixed to the member to be fastened 4 becomes an obstacle, further lower the bit 1. Also, the projection is performed while the screw 3 is held by the metal fitting 5, and the screw 3 does not fall off.
この場合、金具５の直径Ｄはネジ３に装着された座金７
の直径d1とほぼ同じ大きさで、吸着パイプ２の直径d2よ
り小さく形成されるため、吸着パイプ２の降下ができな
くても、金具５を降下させることは行える。In this case, the diameter D of the metal fitting 5 is the washer 7 attached to the screw 3.
Since it is formed to have a size substantially the same as the diameter d1 of the suction pipe 2 and smaller than the diameter d2 of the suction pipe 2, the metal fitting 5 can be lowered even if the suction pipe 2 cannot be lowered.
そこで、（ｄ）に示すように、ネジ３の先端3Cを被締付
部材４の締め付けるべきネジ穴4A−２に確実に螺着させ
ることが行え、前述のようなネジ３の脱落によってネジ
３を損傷させることを防ぐことができる。Therefore, as shown in (d), the tip 3C of the screw 3 can be securely screwed into the screw hole 4A-2 to be tightened in the member to be tightened 4, and the screw 3 can be removed by dropping the screw 3 as described above. Can be prevented from damaging.
また、この場合の金具５は、第３図（ｂ）に示すよう

面には凹部5Aをそれぞれ設けることで形成された金具５
−１を固定ピン5Dによってビット１の先端部1Aに係止さ
せる構成でも良い。Further, the metal fitting 5 in this case is formed by providing a through hole 5C at the center of a tubular body having a diameter D and a recess 5A at the end face, as shown in FIG. 3 (b). Metal fittings 5
-1 may be configured to be locked to the tip portion 1A of the bit 1 by the fixing pin 5D.
但し、この場合は、ビット１の先端部1Aに通気溝1Cを設
け、中空部2Aに於ける吸引が通気溝1Cによって行われる
ようにする必要がある。However, in this case, it is necessary to provide the ventilation groove 1C in the tip portion 1A of the bit 1 so that the suction in the hollow portion 2A is performed by the ventilation groove 1C.

る。As described above, according to the present invention, the metal fitting provided with the recess for holding the head of the screw at the tip of the pit provided in the suction pipe is projected to the place where the screw is tightened. Even if there is an obstacle such as a part, the screw can be screwed by projecting the metal fitting from the suction pipe so that the screw does not drop from the tip portion of the bit.
したがって、従来のようなネジがビットの先端部から脱
落することで、再度ネジを吸着パイプの中空部に吸着さ
せることは不要となり、実用的効果は大である。Therefore, it is not necessary to re-suck the screw into the hollow portion of the suction pipe by dropping the screw from the tip of the bit as in the conventional case, and the practical effect is great.
