Description

本発明は、方向性を有する形状の部品を搬送しながらその姿勢を揃えて次工程に供給する振動式部品供給装置に関する。   The present invention relates to a vibration-type component supply device that supplies a component having a directionality to the next process while aligning its posture.

一般に、自動車等の電装ケーブルの端子部には、防水対策として筒状の防水シールが挿入されており、その挿入加工は端子圧着装置で行われる。この防水シールには挿入端側となる一端部が中央部や他端部よりも小径に形成されたものが多く（図１０参照）、このような方向性を有する形状の防水シールを所定の姿勢で端子圧着装置に供給するために、振動式の部品供給装置がよく使用される。   Generally, a tubular waterproof seal is inserted into a terminal portion of an electrical cable of an automobile or the like as a waterproof measure, and the insertion process is performed by a terminal crimping device. Many of these waterproof seals have one end on the insertion end side having a smaller diameter than the center and the other end (see FIG. 10). In order to supply to the terminal crimping device, a vibration type component supply device is often used.

上記防水シール用の振動式部品供給装置では、防水シールを振動により搬送しながら、小径の一端部が上向きの姿勢（立たせた姿勢）に揃えて端子圧着装置に供給する方式のものが一般的である。しかし、最近の防水シールは、ワイヤーハーネスの細線化や軽量化に伴う小型化により、直径に対する長さの比が大きく倒れやすくなっているため、一般的な方式の部品供給装置では効率よく姿勢を揃えることが困難になっている。   In the above-described vibration-type component supply device for waterproof seals, a method is generally used in which a waterproof seal is conveyed by vibration and one end portion of a small diameter is supplied to a terminal crimping device in an upward posture (standing posture). is there. However, recent waterproof seals are more likely to collapse due to the reduction in the size of wire harnesses as they become thinner and lighter. It is difficult to align.

これに対して、特許文献１および特許文献２では、上記のような方向性を有しかつ倒れやすい形状の部品を所定姿勢で効率よく供給するための部品供給装置が提案されている。このうち、特許文献１には、回転ドラムの外周面に、部品小径部の外径より大きく、部品大径部の外径より小さい内径の吸引嵌合孔を多数設け、部品をこの孔に吸引して、小径部を孔に嵌合させるかまたは大径部先端を孔縁に吸着した状態で回転ドラムの回転によって移動させ、移動中に大径部先端を吸着された部品はエアで吹き飛ばし、小径部を孔に嵌め込まれた部品は一対の無端ベルトで挟んで孔から取り出し下流側へ搬送する部品供給装置が記載されている。   On the other hand, Patent Document 1 and Patent Document 2 propose a component supply device for efficiently supplying a component having the above-described directionality and a shape that easily falls down in a predetermined posture. Among these, in Patent Document 1, a large number of suction fitting holes having an inner diameter larger than the outer diameter of the component small diameter portion and smaller than the outer diameter of the component large diameter portion are provided on the outer peripheral surface of the rotating drum, and the components are sucked into the holes. Then, the small diameter part is fitted into the hole or moved by rotation of the rotating drum with the large diameter part tip adsorbed to the hole edge, and the part adsorbed at the large diameter part tip during the movement is blown off with air, A component supply device is described in which a component having a small-diameter portion fitted in a hole is sandwiched between a pair of endless belts and is taken out from the hole and conveyed downstream.

一方、特許文献２には、円盤状の回転体の周縁に、小径部を回転体中心に向けた姿勢の部品だけを収容する凹部を設け、この凹部に収容された部品を回転体の回転によって移動させ、部品を収容した凹部が回転体の外周側を覆うカバーにあけられた取出口の位置にきたときに、部品を吸引して凹部から取り出し下流側へ搬送する部品供給装置が記載されている。   On the other hand, in Patent Document 2, a concave portion that accommodates only a component in a posture in which the small-diameter portion is directed toward the center of the rotating body is provided at the periphery of the disk-shaped rotating body, and the component accommodated in the concave portion is rotated by the rotation of the rotating body. A component supply device is described in which a component is moved and sucked out from the recess and conveyed to the downstream side when the recess containing the component comes to the position of the outlet opened in the cover covering the outer peripheral side of the rotating body. Yes.

しかしながら、上記特許文献１および特許文献２に記載された装置は、いずれも部品整列部に設けた多数の孔や凹部に部品を一つひとつ嵌め込んで姿勢を揃えた後、孔や凹部から部品を取り出して次工程に供給する方式であるため、孔や凹部を有する整列部材の加工に手間がかかるうえ、部品取出手段を必要とする等、構造が複雑で組立や調整の作業負荷が大きく、トータルコストが一般的な方式のものに比べてかなり高くなる。また、装置全体が大型化し、より大きな設置スペースが必要となるという問題もある。
特開２００４−４３１６２号公報 特開２００４−３０７１３１号公報 However, in the devices described in Patent Document 1 and Patent Document 2, all of the devices are fitted into a large number of holes and recesses provided in the component aligning portion to align the posture one by one, and then the components are taken out from the holes and recesses. Since it is a system that supplies it to the next process, it takes time to process the alignment member with holes and recesses, and it requires parts removal means. Is considerably higher than that of the general method. In addition, there is a problem that the entire apparatus is enlarged and a larger installation space is required.

本発明の課題は、簡単な構造で、一端部が小径の筒状部品を所定姿勢で効率よく次工程に供給できる部品供給装置を提供することである。   An object of the present invention is to provide a component supply apparatus that can supply a cylindrical component having a simple structure and a small diameter at one end to a subsequent process efficiently in a predetermined posture.

上記の課題を解決するため、本発明は、軸方向の一端部が中央部と他端部のいずれよりも小径に形成された筒状部品を搬送する搬送路に、前記部品の姿勢を揃える部品整列部を設けて、前記部品を姿勢の揃った状態で次工程に供給する振動式部品供給装置において、前記部品整列部が、前記搬送路の途中から前記部品を一端部が下向きの姿勢で落下させる整列機構と、落下した部品の一端部が嵌まり込む搬送溝を有するシュートとを備え、前記シュートの搬送溝で部品を一端部が下向きの姿勢のまま下流側へ搬送するものとした。   In order to solve the above-described problems, the present invention provides a component that aligns the posture of the component in a conveyance path that conveys a cylindrical component in which one end portion in the axial direction is formed to have a smaller diameter than both the central portion and the other end portion. In the vibration-type component supply device that provides an alignment unit and supplies the component to the next process in a state where the posture is aligned, the component alignment unit drops the component from the middle of the conveyance path with one end facing downward And a chute having a conveying groove into which one end of the dropped component is fitted, and the component is conveyed downstream with the one end of the chute conveying groove in a downward posture.

すなわち、筒状部品を小径一端部が下向きの姿勢で落下させ、落下した部品を一端部がシュートの搬送溝に嵌まり込んだ状態で下流側へ搬送する方式とすることにより、部品が嵌まり込む孔や凹部を多数加工した整列部材や部品取出手段を必要としない簡単な構造で、部品を所定姿勢で効率よく次工程に供給できるようにしたのである。   That is, the cylindrical part is dropped with one end of the small diameter facing downward, and the dropped part is transferred to the downstream side with the one end inserted into the transfer groove of the chute, so that the part is fitted. With a simple structure that does not require an alignment member or parts extraction means in which a large number of holes and recesses are machined, the parts can be efficiently supplied to the next process in a predetermined posture.

上記の構成において、前記整列機構としては、前記搬送路の床面に前記部品の軸を含む断面形状に対応した形状の開口を設け、この開口の中央部の幅を部品の中央部外径と他端部外径のいずれよりも広く、開口中央部の長さを部品の中央部の長さよりも長くかつ部品の一端部を除く長さよりも短く、開口両端部の幅を部品の一端部外径よりも広くかつ他端部外径よりも狭くそれぞれ形成するとともに、前記搬送路を倒れた姿勢で搬送されてくる部品をその中央部全体が開口中央部に入り込む位置に案内する部品案内手段を設けたものを採用することができる。   In the above configuration, as the alignment mechanism, an opening having a shape corresponding to a cross-sectional shape including the axis of the component is provided on the floor surface of the conveyance path, and the width of the central portion of the opening is defined as the outer diameter of the central portion of the component. It is wider than any of the outer diameters of the other end, the length of the center of the opening is longer than the length of the center of the part and shorter than the length excluding one end of the part, and the width of both ends of the opening is outside the end of the part A component guide means for forming a component that is wider than the diameter and narrower than the outer diameter of the other end, and that guides the component that is conveyed in a tilted posture to the position where the entire central portion enters the central portion of the opening. What was provided can be adopted.

また、前記部品案内手段は、前記開口を前記部品が倒れた姿勢で嵌まり込む広さの凹部の床面に設けるようにするとともに、前記搬送路を倒れた姿勢で搬送されてくる部品を前記凹部へ送り込む方向に気体を吹き出すノズルを設けたものとすることができる。   In addition, the component guide means is configured to provide the opening on a floor surface of a concave portion having a width in which the component is fitted in a tilted posture, and the component that is transported in the tilted posture on the transport path The nozzle which blows off gas in the direction sent to a recessed part can be provided.

そして、前記部品がその中央部または他端部にくびれ部を有している場合には、前記シュートの搬送溝の底側に部品の一端部が嵌まり込む狭幅部を、開口側に部品の中央部と他端部のいずれの直径よりも幅寸法の大きい広幅部をそれぞれ形成し、その広幅部の両側面に、前記部品のくびれ部と係合する突条を搬送方向の所定位置から下流側へ向けて設けるとともに、突条始点位置の下流側近傍から上流側へ向けて、狭幅部と広幅部の間の段差面の高さを高くしたガイド部を設けて、前記整列機構から一端部を下向きにしてシュートへ落下してきた部品が、前記搬送溝の突条始点位置よりも上流側では、その一端部を前記搬送溝狭幅部に挿入し中央部を前記搬送溝ガイド部に支持された状態で下流側へ搬送され、前記突条始点位置よりも下流側では、そのくびれ部で前記突条に案内されて下流側へ搬送されていくようにするとよい。これにより、部品の搬送溝内での倒れを防止できるので、部品を安定して次工程へ供給することができる。   When the part has a constricted part at the center or the other end, a narrow part into which one end of the part fits on the bottom side of the chute conveying groove is provided on the opening side. Wide portions having a width dimension larger than any of the diameters of the central portion and the other end portion of each of the wide portions are formed, and protrusions that engage with the constricted portions of the parts are formed on both side surfaces of the wide portion from a predetermined position in the conveying direction. Provided toward the downstream side, and provided with a guide portion with a height of the stepped surface between the narrow width portion and the wide width portion from the vicinity of the downstream side of the protrusion starting point position toward the upstream side, from the alignment mechanism The part that has fallen to the chute with one end facing downward is inserted upstream of the projecting groove starting point position of the conveying groove into the conveying groove narrow width part, and the central part is used as the conveying groove guide part. In the supported state, it is transported downstream, and downstream of the protrusion starting point position. It is may be guided to the projection at the constricted portion so as conveyed toward the downstream side. Thereby, since the fall in the conveyance groove | channel of components can be prevented, components can be stably supplied to the following process.

ここで、前記シュートには、前記搬送溝の突条始点位置の上流側近傍にある部品をシュートから排除する方向に気体を吹き出すノズルを設け、前記突条始点位置の上流側近傍で部品が停止したときに、前記ノズルから気体を吹き出して停止している部品をシュートから排除するようにするとよい。このようにすれば、通常と逆向き（他端部が下向き）の姿勢で整列機構から落下してくる部品があっても、その部品は他端部を搬送溝のガイド部に支持されて、くびれ部と突条の高さ方向位置のずれにより突条に衝突して停止した後、速やかにシュートから排除されるので、部品つまりの発生を確実に防止することができる。   Here, the chute is provided with a nozzle that blows out gas in a direction to remove the part in the vicinity of the upstream side of the protrusion start point of the conveying groove from the chute, and the part stops in the vicinity of the upstream side of the protrusion start point. In this case, it is preferable to remove from the chute the parts that are stopped by blowing gas from the nozzle. In this way, even if there is a part falling from the alignment mechanism in a posture opposite to normal (the other end is downward), the other end is supported by the guide portion of the conveyance groove, Since the constriction part and the protrusion in the height direction position collide with the protrusion and stop, it is quickly removed from the chute, so that the occurrence of parts clogging can be reliably prevented.

また、前記部品のくびれ部がその外周面の他端側に傾斜面を有している場合は、前記シュートの各突条の上面に、前記搬送溝の幅方向に傾斜する傾斜面を形成し、この突条の傾斜面と搬送溝の幅方向中心線とのなす角度を、前記部品のくびれ部傾斜面と軸線のなす角度よりも大きく、かつ９０°よりも小さく設定することにより、部品の突条始点位置での突条との係合をスムーズにし、突条の案内による部品搬送をさらに安定させることができる。   In addition, when the constricted portion of the part has an inclined surface on the other end side of the outer peripheral surface, an inclined surface inclined in the width direction of the conveying groove is formed on the upper surface of each protrusion of the chute. By setting the angle formed between the inclined surface of the ridge and the center line in the width direction of the conveying groove to be larger than the angle formed between the inclined surface of the constricted portion and the axis and smaller than 90 °, Engagement with the ridges at the ridge start point position can be made smooth, and parts conveyance by the ridge guide can be further stabilized.

本発明の振動式部品供給装置は、上述したように、筒状部品を小径一端部が下向きの姿勢で落下させて、その一端部をシュートの搬送溝に嵌め込んだ状態で下流側へ搬送するものであるから、部品を所定姿勢で効率よく次工程に供給でき、しかもその構造が簡単で部品点数が少ない。従って、前述の多数の孔または凹部をもつ方式のものに比べて、製造費が安くなるうえ、組立および調整がしやすく、トータルコストを大幅に削減することができる。また、装置全体がコンパクトになるので、設置スペースも少なくてすむ。   As described above, the vibration-type component supply device of the present invention drops the cylindrical component in a posture in which one end portion of the small diameter is directed downward, and conveys the downstream portion in a state where the one end portion is fitted in the conveyance groove of the chute. Therefore, the parts can be efficiently supplied to the next process in a predetermined posture, and the structure is simple and the number of parts is small. Therefore, the manufacturing cost is lower than that of the above-mentioned type having a large number of holes or recesses, and the assembly and adjustment are easy, and the total cost can be greatly reduced. In addition, since the entire apparatus becomes compact, installation space can be reduced.

以下、図面に基づき、本発明の実施形態を説明する。この振動式部品供給装置は、図１および図２に示すように、２台の振動式直進フィーダ１、２が部品を互いに反対方向に搬送するように並べて配置されたリターン式フィーダで、一方の直進フィーダ１が整列供給用トラフ３を、他方の直進フィーダ２がリターン用トラフ４を有している。また、整列供給の対象とする部品Ｐは、図１０（ａ）、（ｂ）に示した形状の防水シールであり、挿入端側となる先細りの一端部がくびれ部Ｗを有する中央部と直筒状の他端部のいずれよりも小径に形成され、直径に対する長さの比が大きいものとなっている。そして、部品Ｐ中央部のくびれ部Ｗは、外周面に互いに対向する２つの傾斜面を有し、その他端側の傾斜面と部品Ｐの軸線ＯＰのなす角度（くびれ角度）θＰが３０°となるように形成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1 and FIG. 2, this vibration type component supply device is a return type feeder in which two vibration type linearly moving feeders 1 and 2 are arranged side by side so as to convey components in opposite directions. The rectilinear feeder 1 has an alignment supply trough 3, and the other rectilinear feeder 2 has a return trough 4. The parts P to be aligned and supplied are waterproof seals having the shapes shown in FIGS. 10 (a) and 10 (b), and a tapered portion at the insertion end side and a central portion having a constricted portion W and a straight cylinder. It is formed in a smaller diameter than any of the other end portions, and the ratio of the length to the diameter is large. The constricted portion W of the component P central portion has two inclined surfaces facing each other on the outer peripheral surface, an angle (constriction angle) theta P of the axis O P of the inclined surface and the component P of the other end 30 It is formed to be °.

前記一方の直進フィーダ１は、床Ｆに固定される基台５に防振ゴム６を介して振動体７を取り付け、この振動体７を整列供給用トラフ３に連結したもので、振動体７によりトラフ３を往復振動させて、部品Ｐを搬送路８に沿って図面左方向へ搬送し、その排出端から次工程に供給するようになっている。また、他方の直進フィーダ２は、そのリターン用トラフ４を板ばね９で振動体７の連結部材７ａに連結されており、振動体７によりリターン用トラフ４を往復振動させて、整列供給用トラフ３から受け取った部品Ｐを戻し搬送路１０に沿って図面右方向へ搬送し、再び整列供給用トラフ３に供給するようになっている。   The one linear feeder 1 is configured such that a vibrating body 7 is attached to a base 5 fixed to a floor F via an anti-vibration rubber 6, and this vibrating body 7 is connected to an alignment supply trough 3. Thus, the trough 3 is reciprocally oscillated to convey the component P along the conveyance path 8 in the left direction of the drawing and to supply the next process from the discharge end. Further, the other straight advance feeder 2 has its return trough 4 connected to the connecting member 7a of the vibrating body 7 by a leaf spring 9, and the return trough 4 is reciprocally vibrated by the vibrating body 7. 3 is conveyed to the right in the drawing along the return conveyance path 10 and supplied to the alignment supply trough 3 again.

前記整列供給用トラフ３は、上流部分が緩やかな上り勾配の傾斜部１１となっており、その下流側に部品Ｐの整列搬送を行う部品整列部１２が設けられている。また、搬送路８の側方には、搬送路８から排除された部品Ｐを受けてリターン用トラフ４に送る受板１３が取り付けられている。一方、リターン用トラフ４は、整列供給用トラフ３の受板１３から送られてくる部品Ｐを戻し搬送して再び搬送路８供給端に戻し供給するために、鋸歯状断面の戻し搬送路１０が受板１３排出端の側方から搬送路８供給端の側方まで傾斜した状態で形成されている。   The upstream side of the alignment supply trough 3 is a slanting part 11 with a gentle upward slope, and a part alignment part 12 for aligning and conveying the parts P is provided downstream thereof. A receiving plate 13 that receives the component P removed from the conveyance path 8 and sends it to the return trough 4 is attached to the side of the conveyance path 8. On the other hand, the return trough 4 returns and conveys the part P sent from the receiving plate 13 of the alignment supply trough 3 and supplies it again to the supply end of the conveyance path 8 to supply it again. Is formed in a state of being inclined from the side of the receiving plate 13 discharge end to the side of the conveyance path 8 supply end.

図３および図４に示すように、前記整列供給用トラフ３の部品整列部１２は、軸をほぼ水平方向に向けた姿勢（倒れた姿勢）で搬送されてくる部品Ｐを一端部が下向きの姿勢で落下させる整列機構１４と、落下した部品Ｐの一端側が嵌まり込む搬送溝１５ａを有するシュート１５と、整列機構１４から落下した部品Ｐをシュート１５に導く縦溝１６ａを有するガイド部材１６とからなり、シュート１５の搬送溝１５ａで部品Ｐを一端部が下向きの姿勢のまま下流側へ搬送するようになっている。   As shown in FIGS. 3 and 4, the component aligning section 12 of the alignment supply trough 3 has a component P that is conveyed in a posture in which the shaft is substantially horizontal (falling posture) with one end facing downward. An alignment mechanism 14 that drops in a posture, a chute 15 having a conveyance groove 15a into which one end of the dropped part P is fitted, and a guide member 16 that has a vertical groove 16a that guides the part P dropped from the alignment mechanism 14 to the chute 15. The component P is conveyed downstream by the conveying groove 15a of the chute 15 with one end portion facing downward.

前記整列機構１４は、図５に示すように、搬送路８の床面に部品Ｐの軸を含む断面形状に対応した形状の開口１７を設けるとともに、倒れた姿勢で搬送されてくる部品Ｐを開口１７へ案内する部品案内手段を設けたものである。その開口１７は、中央部の幅Ｂ１が部品Ｐの中央部外径Ｄ１と他端部外径Ｄ３のいずれよりも広く、中央部の長さＡが部品Ｐの中央部の長さＬ１よりも長くかつ部品Ｐの一端部を除く長さＬ０よりも短く、両端部の幅Ｂ２が部品Ｐの一端部最大外径Ｄ２よりも広くかつ他端部外径Ｄ３よりも狭く形成されている（図１０参照）。また、部品案内手段は、図３および図５に示したように、搬送路８の側壁に部品Ｐが倒れた姿勢で嵌まり込む広さの凹部１８を設け、この凹部１８の床面に前記開口１７を設けるようにするとともに、倒れた姿勢で搬送されてくる部品Ｐを凹部１８へ送り込む方向にエアを吹き出す案内ノズル１９を設けたもので、部品Ｐをその中央部全体が開口１７の中央部に入り込む位置に案内するようになっている。これにより、倒れた姿勢で傾斜部１１を搬送されてきた部品Ｐは、確実に開口１７へ案内され、開口１７を通過するときに一端部を下向きにした姿勢となって落下する。 As shown in FIG. 5, the alignment mechanism 14 is provided with an opening 17 having a shape corresponding to a cross-sectional shape including the axis of the component P on the floor surface of the conveyance path 8, and the component P conveyed in a tilted posture. A part guiding means for guiding to the opening 17 is provided. The opening 17 has a width B 1 at the center part wider than both the center part outer diameter D 1 and the other end part outer diameter D 3 of the part P, and a center part length A is the length of the center part of the part P. It is longer than L 1 and shorter than the length L 0 excluding one end of the component P, the width B 2 at both ends is wider than the maximum outer diameter D 2 at one end of the component P, and from the outer diameter D 3 at the other end. Is also narrowly formed (see FIG. 10). Further, as shown in FIGS. 3 and 5, the component guiding means is provided with a concave portion 18 having a width that fits in a posture in which the component P is tilted on the side wall of the conveyance path 8, and the floor surface of the concave portion 18 An opening 17 is provided, and a guide nozzle 19 is provided to blow out air in a direction in which the component P conveyed in a tilted posture is fed into the recess 18. The central portion of the component P is the center of the opening 17. It is designed to guide you to the position where you want to enter. As a result, the component P that has been transported through the inclined portion 11 in a tilted posture is reliably guided to the opening 17 and dropped in a posture in which one end portion faces downward when passing through the opening 17.

また、前記シュート１５は、図６および図７（ａ）、（ｂ）に示すように、搬送溝１５ａの底側に部品Ｐの一端部が嵌まり込む狭幅部が、開口側に部品Ｐの中央部と他端部のいずれの直径よりも幅寸法の大きい広幅部がそれぞれ形成されており、その広幅部の両側面に搬送方向に延びる一対の突条１５ｂが設けられている。この突条１５ｂは、ガイド部材１６の縦溝１６ａの直下の部分が、落下してきた部品Ｐの中央部を通すための円弧状の切欠き１５ｃを有しており、この切欠き１５ｃを挟む上流部分と下流部分が、それぞれ部品Ｐのくびれ部Ｗと係合する断面三角形状に形成されている。さらに、搬送溝１５ａには、突条１５ｂの下流部分の始点位置の下流側近傍から上流側へ向けて、狭幅部と広幅部の間の段差面の高さを高くしたガイド部１５ｄが設けられている。また、搬送溝１５ａの狭幅部は、全長にわたって部品Ｐ一端部の長さよりも深く形成されている。   Further, as shown in FIGS. 6 and 7A and 7B, the chute 15 has a narrow width part into which one end of the part P is fitted on the bottom side of the conveying groove 15a, and the part P on the opening side. A wide portion having a width larger than any of the diameters of the central portion and the other end portion is formed, and a pair of ridges 15b extending in the transport direction are provided on both side surfaces of the wide portion. This protrusion 15b has an arc-shaped notch 15c through which the central portion of the part P that has fallen has a portion immediately below the vertical groove 16a of the guide member 16, and an upstream that sandwiches the notch 15c. The portion and the downstream portion are each formed in a triangular cross section that engages with the constricted portion W of the component P. Further, the conveyance groove 15a is provided with a guide portion 15d in which the height of the step surface between the narrow width portion and the wide width portion is increased from the downstream vicinity of the start position of the downstream portion of the protrusion 15b to the upstream side. It has been. Further, the narrow width portion of the conveying groove 15a is formed deeper than the length of one end portion of the component P over the entire length.

これにより、前記整列機構１４から一端部を下向きにしてシュート１５へ落下してきた部品Ｐが、搬送溝１５ａの突条１５ｂ下流部分の始点位置よりも上流側では、その一端部を搬送溝１５ａの狭幅部に挿入し中央部をガイド部１５ｄに支持された状態で下流側へ搬送され、突条１５ｂ下流部分の始点位置よりも下流側では、そのくびれ部Ｗで突条１５ｂに案内されて下流側へ搬送されていくようになっている。   As a result, the part P that has fallen to the chute 15 with one end facing downward from the alignment mechanism 14 is located upstream of the starting point position of the downstream portion of the protrusion 15b of the conveying groove 15a. It is inserted into the narrow part and conveyed to the downstream side with the central part supported by the guide part 15d, and is guided to the ridge 15b by the constricted part W on the downstream side of the starting point position of the downstream part of the ridge 15b. It is transported downstream.

ここで、図８（ａ）にも示すように、前記各突条１５ｂの上面は搬送溝１５ａの開口縁から連続して幅方向に傾斜する傾斜面となっており、この傾斜面と搬送溝１５ａの幅方向中心線とのなす角度θＡは、部品Ｐの他端側のくびれ角度θＰ（３０°）よりも大きく、かつ９０°よりも小さく設定されている。これにより、部品Ｐが突条１５ｂ下流部分の始点位置でスムーズに突条１５ｂと係合し、突条１５ｂの案内により安定して下流側へ搬送されていく。なお、部品Ｐ搬送の安定性向上のためには、突条１５ｂの傾斜面角度θＡの上限は６０°程度が好ましく、下限は部品Ｐの他端側くびれ角度θＰよりも１０°程度大きい角度（この例では４０°程度）が好ましい。従って、例えば図８（ｂ）に示すように、他端側くびれ角度θＰが２０°に形成された部品Ｐを対象とする場合は、突条１５ｂの傾斜面角度θＡは、３０〜６０°が好ましい。 Here, as shown in FIG. 8 (a), the upper surface of each protrusion 15b is an inclined surface that inclines in the width direction continuously from the opening edge of the conveying groove 15a. The angle θ A formed with the center line in the width direction of 15a is set to be larger than the constriction angle θ P (30 °) on the other end side of the component P and smaller than 90 °. As a result, the component P smoothly engages with the protrusion 15b at the start position of the downstream portion of the protrusion 15b, and is stably conveyed downstream by the guide of the protrusion 15b. In order to improve the stability of the components P conveyance, the upper limit of the inclination surface angle theta A ridge 15b is preferably about 60 °, the lower limit is about 10 ° greater than the other end constricted angle theta P component P An angle (about 40 ° in this example) is preferable. Therefore, for example, as shown in FIG. 8B, when the other end side constriction angle θ P is a component P formed at 20 °, the inclined surface angle θ A of the ridge 15b is 30-60. ° is preferred.

一方、ガイド部材１６の縦溝１６ａの直下で搬送溝１５ａに嵌まり込まなかった部品Ｐは、倒れた姿勢で突条１５ｂの上面に支えられて搬送される。そして、図３および図４に示したように、搬送溝１５ａの受板１３側の側壁に切欠き１５ｅが形成された位置で、第１の排除ノズル２０から吹き出すエアにより受板１３へ排除されるようになっている。   On the other hand, the component P that has not been fitted into the conveyance groove 15a immediately below the vertical groove 16a of the guide member 16 is supported and conveyed by the upper surface of the protrusion 15b in a tilted posture. Then, as shown in FIGS. 3 and 4, the air is blown out to the receiving plate 13 by the air blown from the first exclusion nozzle 20 at the position where the notch 15e is formed in the side wall of the conveying groove 15a on the receiving plate 13 side. It has become so.

また、図４、図６および図７に示すように、前記シュート１５には、突条１５ｂ下流部分の始点位置の上流側近傍での部品Ｐの停止を検知する光電センサ（図示省略）と、このセンサで部品Ｐの停止が検知されたときに、搬送溝１５ａの下流側、側方および底面のそれぞれからエアを吹き出して、停止している部品Ｐをシュート１５から排除する第２〜第４の排除ノズル２１、２２、２３が設けられている。これにより、図９に示すように、通常と逆向き（他端部が下向き）の姿勢で整列機構１４から落下してくる部品Ｐがあっても、その部品Ｐは他端部を搬送溝１５ａのガイド部１５ｄに支持されて、くびれ部Ｗと突条１５ｂの高さ方向位置のずれにより突条１５ｂに衝突して停止した後、速やかにシュート１５から排除される（第２排除ノズル２１の作用は図示省略）ので、部品つまりの発生を確実に防止することができる。   As shown in FIGS. 4, 6 and 7, the chute 15 includes a photoelectric sensor (not shown) for detecting the stop of the component P in the vicinity of the upstream side of the starting position of the downstream portion of the ridge 15b, When the stop of the component P is detected by this sensor, air is blown out from each of the downstream side, the side, and the bottom surface of the conveying groove 15a to exclude the stopped component P from the chute 15. Exclusion nozzles 21, 22, and 23 are provided. As a result, as shown in FIG. 9, even if there is a part P falling from the alignment mechanism 14 in a posture opposite to the normal direction (the other end portion is downward), the other end portion of the component P is moved to the conveying groove 15a. Is supported by the guide portion 15d, and after colliding with the ridge 15b due to a shift in the height direction position of the constricted portion W and the ridge 15b, it is quickly removed from the chute 15 (the second exclusion nozzle 21). Since the action is not shown), the occurrence of clogging of parts can be surely prevented.

次に、この部品供給装置における部品Ｐの流れを説明する。整列供給用トラフ３の搬送路８供給端に供給された部品Ｐは、ほとんどが振動により倒れた姿勢となって傾斜部１１を登坂し、部品整列部１２へと搬送される。部品整列部１２に搬送されてきた部品Ｐは、まず案内ノズル１９から吹き出すエアで開口１７のある凹部１８へ送り込まれて、一端部を下向きにした姿勢で開口１７から落下し、ガイド部材１６の縦溝１６ａを通ってシュート１５上面に達する。そして、落下してきた部品Ｐの多くは、その一端部を搬送溝１５ａの狭幅部に嵌め込まれる形でシュート１５に受け止められ、そのままの姿勢で搬送溝１５ａのガイド部１５ｄおよび突条１５ｂに案内されて下流側へ搬送され、次工程の端子圧着装置（図示省略）に供給される。   Next, the flow of the component P in this component supply apparatus will be described. Most of the parts P supplied to the supply path 8 supply end of the alignment supply trough 3 are tilted by the vibration, climb up the inclined part 11, and are conveyed to the part alignment part 12. The component P conveyed to the component aligning unit 12 is first sent to the recess 18 having the opening 17 by the air blown from the guide nozzle 19, and falls from the opening 17 in a posture in which one end portion is directed downward. It reaches the upper surface of the chute 15 through the vertical groove 16a. Many of the parts P that have fallen are received by the chute 15 in such a manner that one end thereof is fitted into the narrow width portion of the conveying groove 15a and guided to the guide portion 15d and the protrusion 15b of the conveying groove 15a in the same posture. Then, it is conveyed downstream and supplied to a terminal crimping device (not shown) in the next process.

一方、搬送溝１５ａに嵌まり込まなかった一部の部品Ｐは、倒れた姿勢で突条１５ｂの上面に支えられて搬送され、途中で第１排除ノズル２０から吹き出すエアで受板１３へ排除される。また、他端部を下向きにして落下してくる部品Ｐがあっても、その部品Ｐは他端部を搬送溝１５ａのガイド部１５ｄに支持された状態で突条１５ｂに衝突して停止し、第２〜第４排除ノズル２１、２２、２３から吹き出すエアによりシュート１５から排除される。そして、このようにシュート１５から排除された部品Ｐは、受板１３からリターン用トラフ４に送られて戻し搬送路１０で搬送され、再び整列供給用トラフ３に戻される。   On the other hand, some of the parts P that have not been fitted into the conveying groove 15a are supported by the upper surface of the protrusion 15b in a tilted posture, and are excluded to the receiving plate 13 by air blown from the first exclusion nozzle 20 in the middle. Is done. Even if there is a part P falling with the other end facing downward, the part P collides with the ridge 15b and stops with the other end supported by the guide part 15d of the conveying groove 15a. The air blown out from the second to fourth exclusion nozzles 21, 22 and 23 is excluded from the chute 15. Then, the part P thus removed from the chute 15 is sent from the receiving plate 13 to the return trough 4, transported in the return transport path 10, and returned to the alignment supply trough 3 again.

この部品供給装置は、上記の構成であり、部品Ｐを小径一端部が下向きの姿勢で落下させ、落下した部品Ｐを一端部がシュート１５の搬送溝１５ａに嵌まり込んだ状態で下流側へ搬送する方式となっているため、簡単な構造で、部品Ｐを効率よく次工程に供給することができる。   This component supply apparatus is configured as described above, and the component P is dropped with one end portion having a small diameter facing downward, and the dropped component P is moved downstream with one end portion fitted into the conveying groove 15a of the chute 15. Since it is a conveyance system, the part P can be efficiently supplied to the next process with a simple structure.
