本発明は小ねじ等の部品を(□共給するために用いられ
る部品供給ヘッドに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a parts supply head used for co-feeding parts such as machine screws.
例えば小ねじ等の比較的小さな形状の部品を取扱う部品
供給ヘッドとして、部品自体に作用する重力を利用する
ようにしたものがある。これは、供給筒を備え、この供
給筒内に供給された部品を一個ずつ内周面に沿って重力
落下させるように構成されている。For example, as a component supply head for handling relatively small-shaped components such as machine screws, there is a component supply head that utilizes gravity acting on the component itself. This is equipped with a supply tube, and is configured to cause the parts supplied into the supply tube to fall one by one along the inner circumferential surface by gravity.
しかし、このように供給筒内を重力落下させる構造では
、部品を円滑に落下させるために、供給筒の内径を部品
の外形形状よりも大きくし、部品と供給筒の内周面との
間にある程度の間隙を設けざるを得゛ない。そのため、
部品が傾いた姿勢で落下したり、供給筒内部の一方に偏
った状態で落下する場合があった。その結果、供給筒を
正確に位置決めしても、部品は必ずしも正確には位置決
めできないという不具合があった。そして、部品が小ね
じである場合にはねじ孔に傾いて挿入されたり、ねじ孔
からずれて挿入されない場合があった。However, in this structure where the inside of the supply cylinder is allowed to fall by gravity, in order to allow parts to fall smoothly, the inner diameter of the supply cylinder is made larger than the external shape of the part, and there is a gap between the parts and the inner peripheral surface of the supply cylinder. A certain amount of space must be provided. Therefore,
There were cases in which parts fell in an inclined position or were biased to one side inside the supply tube. As a result, there was a problem in that even if the supply cylinder was positioned accurately, the parts could not necessarily be positioned accurately. When the component is a small screw, the component may be inserted into the screw hole at an angle, or may not be inserted out of the screw hole.
本発明はこのような事情に鑑みなされたもので、部品を
正確に位置決めすることができる部品供給ヘッドを提供

孔を円周方向に等間隔をおいて設けたものである。The present invention has been made in view of the above circumstances, and provides a component supply head that can accurately position components. A plurality of inflow holes are provided at equal intervals in the circumferential direction on the peripheral wall of the supply cylinder that is allowed to fall by gravity, through which uniformly pressurized compressed air flows into the inside.
本発明においては、流入孔から流入する圧縮空気の圧力

図示しないが圧縮空気供給源に接続されている。14 is a container member provided below the slide member 13. This container member 14 has a relatively large shape compared to the supply tube 11, and has an annular chamber 15 that covers the outside of the supply tube 11.
is formed. This annular chamber 15 is for equalizing the pressure of compressed air flowing into the supply cylinder 11 from an inflow hole, which will be described later. An annular chamber 1 is provided on the outer peripheral wall of the container member 14.
A connecting joint 16 is provided that communicates the inside and outside of 5. 17 is a hose connected to this connection joint 16,
Although not shown, it is connected to a compressed air supply source.
前記供給筒11の周壁の環状室15に対向する部位には

入孔21が円周方向に等間隔をおいて穿設されている。A plurality of inflow holes 21 for allowing compressed air in the annular chamber 15 to flow into the annular chamber 15 are bored at equal intervals in the circumferential direction at a portion of the peripheral wall of the supply tube 11 facing the annular chamber 15.
本実施例においては、4個の流入孔21が下方であって

近に4個円周方向に等間隔をおいて設けられている。In this embodiment, the four inflow holes 21 are located downward and are oriented rightward with respect to the center of the supply tube 11 . Therefore, in this embodiment, the compressed air flows spirally as shown by the dotted chain line in FIGS. 1 and 2. 22
are exhaust holes for discharging the air that has flowed into the supply cylinder 11 from the inflow hole 21 to the outside, and four exhaust holes are provided near the lower open end of the supply cylinder 11 at equal intervals in the circumferential direction.

対応した位置に位置決めされる。In the component supply head configured in this manner, the supply cylinder 11 is positioned by the arm 5 of the robot device 4 at a position corresponding to the screw hole 9a of the workpiece 9, the through hole 8a of the workpiece 8, and the counterbore 8b.
そして、スライダ部材13を後退させることによって、
小ねじ12は重力落下する。Then, by retreating the slider member 13,
The machine screw 12 falls due to gravity.
一方、図示しない圧縮空気供給源から環状室15内へ供
給された圧縮空気は、環状室15で圧力が均一化された
後に、流入孔21から均等に供給筒11内部に流入する

いては圧力が高く、流入孔21から離れた中央部におい
ては圧力が低くなるので、この圧力差によって上方から
落下してくる小ねじ12を供給筒11の中央に案内し、
姿勢を供給筒11の軸線方向に修正することができる。On the other hand, compressed air supplied into the annular chamber 15 from a compressed air supply source (not shown) equalizes the pressure in the annular chamber 15, and then evenly flows into the supply cylinder 11 from the inflow hole 21. The pressure of this compressed air is high in the peripheral area near the inflow hole 21, and the pressure is low in the central area away from the inflow hole 21, so this pressure difference supplies the machine screw 12 falling from above. Guide it to the center of the tube 11,
The attitude can be corrected in the axial direction of the supply cylinder 11.
したがって、小ねじ12と内周面との間に間隙が設けら
れていても、小ねじ12の姿勢および位置を供給筒11
に対して決定することができるから、小ねじ12を正確
に位置決めし、ねじ孔9aに正確に挿入することができ
る。Therefore, even if a gap is provided between the machine screw 12 and the inner circumferential surface, the posture and position of the machine screw 12 can be adjusted to the supply cylinder 11.
Therefore, the machine screw 12 can be accurately positioned and accurately inserted into the screw hole 9a.
また、実施例においては、圧縮空気を螺旋状に流入させ

落下姿勢を安定させるだけでなく、小ねじ12をねし孔
9aのねし溝に1〜2山を螺合させることもできる。In addition, in the embodiment, since the compressed air is made to flow in in a spiral manner, if the strength of the compressed air is made strong enough to rotate the machine screw 12, the falling posture of the machine screw 12 can be prevented. In addition to stabilization, one or two threads of the machine screw 12 can be screwed into the threaded groove of the threaded hole 9a.
さらには、供給筒11の開口端付近に排気孔22を設け
ており、小ねじ12を落下させるときに開口端をめいっ
ばいワーク8の表面に近接させることできるので、位置
決めを一層正確にすることができる。Furthermore, the exhaust hole 22 is provided near the open end of the supply cylinder 11, and when dropping the machine screw 12, the open end can be brought as close as possible to the surface of the workpiece 8, making positioning even more accurate. Can be done.
なお、上記実施例においては、部品として小ねじ12を
供給した例について説明したが、本発明はこれに限定さ

ようにすれば、必ずしも設ける必要はない。Further, the number, shape, and orientation direction of the inflow holes 21 can be changed as appropriate. Further, the annular chamber 15 is provided as a means for equalizing the pressure of the compressed air flowing into the supply cylinder 11 from the inflow hole 21, and each inflow hole 21 is connected to each inlet hole 21 by a hose or the like to supply compressed air of uniform pressure. It is not necessarily necessary to provide it if it is connected in parallel to the compressed air supply source (for example, an air tank) that supplies the air.

方向に修正することができる。As explained above, according to the present invention, a plurality of inflow holes through which uniformly pressurized compressed air flows into the peripheral wall of the supply cylinder, which allows parts to fall by gravity along the inner peripheral surface, are arranged at equal intervals. Because of this provision, the components falling due to gravity can be guided to the center of the supply cylinder by the compressed air flowing in from the inflow hole, and the posture can be corrected in the axial direction.
したがって、部品の姿勢および位置を供給筒に対して決
