The bottom portion 14c of the notch 14b has an inclined surface that is inclined downward in the direction of arrow C.

第２のエアシリンダ６は、図１に示すように保持部材３上に固定されており、保持部材３の矢印Ａ−Ｂ方向への移動に対して一体的に移動する。この第２のエアシリンダ６のロッド６ａの先端部には、この第２のエアシリンダ６に矢印Ｃ−Ｄ方向に移動自在に支持された第２移動体１６が取り付けられている。送り出し部材５は、押し当て片１４が保持部材３の保持溝３ａ内に嵌入され、かつ下端面が保持部材３の上端面に対向するように第２移動体１６に取り付けられている。   As shown in FIG. 1, the second air cylinder 6 is fixed on the holding member 3, and moves integrally with the movement of the holding member 3 in the arrow AB direction. A second moving body 16 that is supported by the second air cylinder 6 so as to be movable in the direction of the arrow CD is attached to the tip of the rod 6a of the second air cylinder 6. The feeding member 5 is attached to the second moving body 16 so that the pressing piece 14 is fitted into the holding groove 3 a of the holding member 3 and the lower end surface thereof faces the upper end surface of the holding member 3.

このような構成において、第２のエアシリンダ６のロッド６ａが後退した図１の状態では、同図（Ｂ）に示すように送り出し部材５の矢印Ｃ方向の端面と保持部材３の矢印Ｃ方向の端面とが一致している。このとき、第１のエアシリンダ４のロッド４ａが後退している場合は、同図（Ａ）に示すように保持部材５の凹部５ａがガイドブロック１０の案内溝１０ａに対応している。この状態では、ガイドブロック１０の案内溝１０ａから１個のねじ２が保持部材３に供給されると、供給されたねじ２の軸部２ｂが保持溝３ａ内に嵌入され、頭部２ａが保持溝３ａの上端縁に係止された状態で送り出し部材５の凹部５ａ内に嵌入される。この状態でねじ２は、軸部２ｂの外周面が押し当て片１４の軸部押し当て部１４ａに押し当てられ、頭部２ａの外周面が送り出し部材５の頭部押し当て部５ｂに押し当てられ、直立状態のまま保持部材３に保持される。   In such a configuration, in the state of FIG. 1 in which the rod 6a of the second air cylinder 6 is retracted, the end surface in the direction of arrow C of the delivery member 5 and the direction of arrow C of the holding member 3 as shown in FIG. The end face of the is consistent. At this time, when the rod 4a of the first air cylinder 4 is retracted, the concave portion 5a of the holding member 5 corresponds to the guide groove 10a of the guide block 10 as shown in FIG. In this state, when one screw 2 is supplied from the guide groove 10a of the guide block 10 to the holding member 3, the shaft portion 2b of the supplied screw 2 is fitted into the holding groove 3a, and the head 2a is held. The groove 3a is fitted into the recess 5a of the delivery member 5 while being locked to the upper edge of the groove 3a. In this state, the screw 2 has its outer peripheral surface pressed against the shaft pressing portion 14a of the pressing piece 14 and its outer peripheral surface pressed against the head pressing portion 5b of the feeding member 5. And is held by the holding member 3 in an upright state.

次いで、第１のエアシリンダ４のロッド４ａが前進すると、図２（Ａ）に示すように送り出し部材５が保持部材３と一体的に矢印Ａ方向に移動し、凹部５ａが貫通孔７に対応する。この状態から第２のエアシリンダ６のロッド６ａが前進すると、送り出し部材５が矢印Ｃ方向に移動し、頭部押し当て部５ｂと軸部押し当て部１４ａが貫通孔７に進出する。図１において、１８は貫通孔７が設けられたブロックであって、基台１１に取り付けられており、貫通孔７の口径はねじ２の頭部２ａの径よりもやや大きく形成されている。貫通孔７の上部側開口は保持部材３の上端面と高さが一致し、下部側開口は基台１１に形成した貫通孔１９に連通されており、両貫通孔７，１９を落下したねじ２は、このねじ２によって締結される部材（図示せず）のねじ孔に導かれる。   Next, when the rod 4a of the first air cylinder 4 moves forward, the delivery member 5 moves integrally with the holding member 3 in the direction of arrow A as shown in FIG. 2 (A), and the recess 5a corresponds to the through hole 7. To do. When the rod 6a of the second air cylinder 6 advances from this state, the delivery member 5 moves in the direction of arrow C, and the head pressing portion 5b and the shaft pressing portion 14a advance into the through hole 7. In FIG. 1, reference numeral 18 denotes a block provided with a through hole 7, which is attached to the base 11, and the diameter of the through hole 7 is formed to be slightly larger than the diameter of the head 2 a of the screw 2. The opening on the upper side of the through hole 7 coincides with the upper end surface of the holding member 3, the opening on the lower side is communicated with the through hole 19 formed in the base 11, and the screw that has dropped through both the through holes 7, 19. 2 is guided to a screw hole of a member (not shown) fastened by the screw 2.

次に、図１ないし図４および図７ないし図１０を用いて、このように構成された締結部品搬送装置１によってねじ２を搬送する動作について説明する。先ず、第１のエアシリンダ４のロッド４ａが後退し、かつ第２のエアシリンダ６のロッド６ａが後退した図１および図７に示す状態で、上述したようにガイドブロック１０の案内溝１０ａから、保持部材３の保持溝３ａに１個のねじ２が供給される。   Next, with reference to FIGS. 1 to 4 and FIGS. 7 to 10, an operation of conveying the screw 2 by the fastening part conveying apparatus 1 configured as described above will be described. First, in the state shown in FIGS. 1 and 7 in which the rod 4a of the first air cylinder 4 is retracted and the rod 6a of the second air cylinder 6 is retracted, the guide groove 10a of the guide block 10 is removed as described above. The one screw 2 is supplied to the holding groove 3a of the holding member 3.

次いで、第１のエアシリンダ４のロッド４ａを前進させることにより、保持部材３と送り出し部材５とを矢印Ａ方向へ移動させ、保持部材３の保持溝３ａと送り出し部材５の頭部押し当て部５ｂおよび軸部押し当て部１４ａとによって保持されたねじ２を、図２および図８に示すように貫通孔７に対応させる。   Next, by moving the rod 4a of the first air cylinder 4 forward, the holding member 3 and the delivery member 5 are moved in the direction of arrow A, and the holding groove 3a of the holding member 3 and the head pressing portion of the delivery member 5 are moved. The screw 2 held by 5b and the shaft pressing portion 14a is made to correspond to the through hole 7 as shown in FIGS.

この状態で、第２のエアシリンダ６のロッド６ａを前進させることにより、図３に示すように送り出し部材５を矢印Ｃ方向へ移動させ、送り出し部材５の頭部押し当て部５ｂおよび軸部押し当て部１４ａとによって、図９に示すようにねじ２を貫通孔７上に位置付け、保持部材３によるねじ２の保持を解除する。貫通孔７上に位置付けられ、保持部材３による保持を解除されたねじ２は、貫通孔７内を直立した状態で自重によって落下する。   In this state, the rod 6a of the second air cylinder 6 is moved forward to move the delivery member 5 in the direction of arrow C as shown in FIG. 3, and the head pressing portion 5b and the shaft portion push of the delivery member 5 are moved. With the abutting portion 14a, the screw 2 is positioned on the through hole 7 as shown in FIG. 9, and the holding of the screw 2 by the holding member 3 is released. The screw 2 positioned on the through hole 7 and released from being held by the holding member 3 falls by its own weight while standing upright in the through hole 7.

このように、ねじ２の頭部２ａの外周面に頭部押し当て部５ｂを押し当て、同時に軸部２ｂの外周面に軸部押し当て部１４ａを押し当てているため、ねじ２を送り出すときにねじ２の倒れ込みが防止され直立状態が維持されるからねじ２が貫通孔７内で詰まるようなことがない。また、送り出し部材５にねじ２の頭部２ａの上面に対向する対向部５ｃを設けたことにより、送り出し部材５によってねじ２が貫通孔７へ送り出されるときに、ねじ２の回動が規制されるためねじ２の倒れ込みをより一層防止することができる。   In this way, when the screw 2 is fed out, the head pressing portion 5b is pressed against the outer peripheral surface of the head 2a of the screw 2 and the shaft pressing portion 14a is pressed against the outer peripheral surface of the shaft portion 2b at the same time. Therefore, the screw 2 is prevented from falling and the upright state is maintained, so that the screw 2 is not clogged in the through hole 7. Further, since the feeding member 5 is provided with the facing portion 5c facing the upper surface of the head 2a of the screw 2, the rotation of the screw 2 is restricted when the screw 2 is fed to the through hole 7 by the feeding member 5. Therefore, the fall of the screw 2 can be further prevented.

第２のエアシリンダ６のロッド６ａを前進させることにより、送り出し部材５を貫通孔７側に進出させた直後に、第２のエアシリンダ６のロッド６ａを後退させることにより、図４に示すように送り出し部材５を矢印Ｄ方向へ移動させ、送り出し部材５を貫通孔５側から退出させる。このとき、送り出し部材５の軸部押し当て部１４ａに切欠き１４ｂを設けたことにより、軸部押し当て部１４ａがねじ２の頭部２ａの下面に摺接するようなことがないため、ねじ２の倒れ込みを防止することができる。   As shown in FIG. 4, the rod 6 a of the second air cylinder 6 is moved forward so that the rod 6 a of the second air cylinder 6 is retracted immediately after the feeding member 5 is advanced toward the through hole 7. Then, the delivery member 5 is moved in the direction of arrow D, and the delivery member 5 is retracted from the through hole 5 side. At this time, since the notch 14b is provided in the shaft pressing portion 14a of the delivery member 5, the shaft pressing portion 14a does not come into sliding contact with the lower surface of the head 2a of the screw 2. Can be prevented from falling down.

また、ねじ２が貫通孔７内を自重によって落下するとき、仮に頭部２ａが切欠き１４ｂの底部１４ｃに接触したとしても、底部１４ｃが傾斜面に形成されていることにより、頭部２ａと底部１４ｃとが面接触するようなことがない。このため、ねじ２は貫通孔７から退出する送り出し部材５の底部１４ｃにねじ２が随伴するようなことがないからねじ２の倒れ込みを防止することができる。   Further, when the screw 2 falls through the through-hole 7 due to its own weight, even if the head portion 2a contacts the bottom portion 14c of the notch 14b, the bottom portion 14c is formed on the inclined surface. There is no surface contact with the bottom 14c. For this reason, since the screw 2 does not accompany the bottom portion 14c of the delivery member 5 that retreats from the through hole 7, the screw 2 can be prevented from falling down.

次いで、第１のエアシリンダ４のロッド４ａを後退させることにより、図１に示すように保持部材３と送り出し部材５とを矢印Ｂ方向に移動させ、送り出し部材５の凹部５ａをガイドブロック１０の案内溝１０ａに対応させる。このとき、ガイドブロック１０の案内溝１０ａからねじ２の頭部２ａの一部が送り出し部材５側に臨んでいたとしても、送り出し部材５に凹部５ａに連通した溝５ｄが設けられているため、頭部２ａがこの溝５内に嵌入するから頭部２ａが送り出し部材５と干渉するようなことがない。   Next, by retracting the rod 4a of the first air cylinder 4, the holding member 3 and the delivery member 5 are moved in the direction of arrow B as shown in FIG. It corresponds to the guide groove 10a. At this time, even if a part of the head 2a of the screw 2 faces the delivery member 5 side from the guide groove 10a of the guide block 10, the delivery member 5 is provided with the groove 5d communicating with the recess 5a. Since the head 2 a is fitted into the groove 5, the head 2 a does not interfere with the delivery member 5.
