　ケース本体部７２は、２つの板材８０，８２が重ね合わされて形成されている。図４に示すように、手前側の板材８０には、奥側の板材８２に面する側面に、部品収容凹所８４が形成されており、この部品収容凹所８４によって、ケース本体部７２の内部には、部品Ｐが収容される空間である部品収容空間８６が形成されている。この部品収容空間８６の上部の開口が、上述の投入口７７として機能する。蓋７８は、板材８０の上部にスライド可能に支持され、スプリング８８によって投入口７６が閉まる方向に付勢されている。 The case body 72 is formed by overlapping two plate members 80 and 82. As shown in FIG. 4, the front plate member 80 is formed with a component housing recess 84 on the side surface facing the back plate member 82, and the component housing recess 84 allows the case main body 72 to A component housing space 86 that is a space in which the component P is housed is formed inside. The opening in the upper part of the component housing space 86 functions as the above-described inlet 77. The lid 78 is slidably supported on the upper part of the plate member 80 and is urged by a spring 88 in a direction in which the insertion port 76 is closed.
　一方で、板材８２には、板材８０に面する側面に、円周の一部、詳しくは、円周の約３／４を構成するように延びる部分と、その部分から延び出すように延びる部分とからなる形状を有する溝が形成されている。この溝は、板材８０に向かって開口しており、部品収容空間８６に開口する約１／２円周の部分は、後に詳しく説明する案内溝９０とされ、残りの部分は、板材８０によって塞がれて、トンネル状の通路とされている。この通路が、上述の移動通路７６の一部を構成している。 On the other hand, the plate member 82 has a portion extending so as to constitute a part of the circumference, specifically, about 3/4 of the circumference, and a portion extending so as to extend from the side surface facing the plate member 80. The groove | channel which has the shape which consists of these is formed. The groove opens toward the plate member 80, and a portion having a circumference of about ½ that opens into the component housing space 86 is a guide groove 90 described in detail later, and the remaining portion is closed by the plate member 80. It is a tunnel-shaped passage. This passage constitutes a part of the moving passage 76 described above.
　また、板材８２の反対側の側面、つまり、ケース本体部７２の外側の側面には、下部が半円状の凹所９２が設けられている。この凹所９２には、ギヤ付きの円盤９４が配設され、その円盤９４のケース本体部７２側の面には、複数の磁石９６、詳しくは、８個の磁石９６が、一円周上に等角度ピッチで保持されている。板材８２は、ケース本体部７２の一側壁、つまり、ケース７０の一側壁となっており、各磁石９６は、その一側壁の外側に設けられて部品収容空間８６の部品Ｐを、その一側壁の内側の面に向かって吸引する。各磁石９６の配設円の一部は、案内溝９０と対応する位置に位置している。 Further, a recess 92 having a semicircular lower portion is provided on the opposite side surface of the plate member 82, that is, on the outer side surface of the case main body 72. A disc 94 with gears is disposed in the recess 92, and a plurality of magnets 96, specifically eight magnets 96, are arranged on one circumference on the surface of the disc 94 on the case main body 72 side. Are held at an equiangular pitch. The plate member 82 is one side wall of the case main body 72, that is, one side wall of the case 70, and each magnet 96 is provided outside the one side wall, and the component P of the component housing space 86 is transferred to the one side wall. Aspirate toward the inner surface of the. A part of the arrangement circle of each magnet 96 is located at a position corresponding to the guide groove 90.
　円盤９４は、図２，図３に示すように、モータ９８の回転によってギヤ１００を介して回転させられ、それによって、複数の磁石９６が、一円周に沿って回転させられる。詳しく言えば、各磁石９６が、図４に示す反時計まわりの回転方向に回転させられることで、つまり、正回転させられることで、部品収容空間８６において、各磁石９６によって吸引されたいくつかの部品Ｐが、案内溝９０に沿って、部品Ｐの溜まりから持ち上げられるようにして移動通路７６に向かって移動させられる。すなわち、モータ９８，ギヤ１００，円盤９４等を含んで、磁石９６を案内溝９０に沿って移動させる磁石移動装置１０２が構成されているのである。そして、その磁石移動装置１０２，磁石９６，案内溝９０等を含んで、部品Ｐをケース本体部７２の部品収容空間８６から移動通路７６に導く上述の移送機構が構成されているのである。 2 and 3, the disk 94 is rotated through the gear 100 by the rotation of the motor 98, whereby the plurality of magnets 96 are rotated along one circumference. More specifically, some of the magnets 96 attracted by each magnet 96 in the component housing space 86 by being rotated in the counterclockwise rotation direction shown in FIG. The part P is moved along the guide groove 90 toward the moving passage 76 so as to be lifted from the pool of the parts P. That is, the magnet moving device 102 that moves the magnet 96 along the guide groove 90 is configured including the motor 98, the gear 100, the disk 94, and the like. And the above-mentioned transfer mechanism which comprises the magnet moving apparatus 102, the magnet 96, the guide groove 90, etc. and guide | induces the components P from the components storage space 86 of the case main-body part 72 to the movement channel | path 76 is comprised.
　案内溝９０の一部を斜めからの視点で示す図５（ａ），案内溝９０の断面を示す図５（ｂ）を参照しつつ、さらに説明すれば、案内溝９０は、部品Ｐが挟まる幅で対向する１対の側面１０４と、それら１対の側面１０４の間を繋ぐ底面１０６とを有する形状とされている。部品Ｐは、幅寸法ｗ，長手寸法ｌ（ｌ＞ｗ）の柱形状をなしており、案内溝９０の幅Ｗ，深さＤは、部品Ｐの幅寸法ｗより僅かに大きくされている。したがって、１つの磁石９６によって移動させられるいくつかの部品Ｐのうちの一部は、案内溝９０に嵌り込んで、１対の側面１０４によって幅方向に挟まれるようにして移動させられる。また、案内溝９０と移動通路７６との境目、つまり、移動通路７６の入り口は、部品収容空間８６からの出口穴１１０として機能する。この出口穴１１０は、正規の姿勢（所定姿勢）で案内溝９０に嵌り込んで移動させられた部品Ｐだけの通過を許容するものとされており、他の姿勢のものは、板材８０の出口穴１１０の周囲の部分によって、部品Ｐの溜まりに落下させられる。言い換えれば、出口穴１１０は、部品Ｐの長手方向の通過だけを許容するのであり、上記部品Ｐの正規の姿勢は、部品Ｐが案内溝９０内に寝た姿勢なのである。出口穴１１０を通過した部品Ｐは、この正規の姿勢のまま、前述の部品供給位置ＰＳまで移動通路７６を移動する。 Further description will be made with reference to FIG. 5A showing a part of the guide groove 90 from a perspective and FIG. 5B showing a cross section of the guide groove 90, and the guide P is sandwiched by the component P. The shape has a pair of side surfaces 104 opposed in width and a bottom surface 106 connecting the pair of side surfaces 104. The component P has a columnar shape with a width dimension w and a longitudinal dimension l (l> w), and the width W and the depth D of the guide groove 90 are slightly larger than the width dimension w of the component P. Accordingly, some of the several parts P moved by one magnet 96 are fitted into the guide groove 90 and moved so as to be sandwiched in the width direction by the pair of side surfaces 104. Further, the boundary between the guide groove 90 and the movement passage 76, that is, the entrance of the movement passage 76 functions as an outlet hole 110 from the component housing space 86. The outlet hole 110 is allowed to pass only the part P that has been fitted and moved in the guide groove 90 in a normal posture (predetermined posture). The part around the hole 110 is dropped into the pool of the parts P. In other words, the outlet hole 110 allows only the passage of the part P in the longitudinal direction, and the normal posture of the part P is a posture in which the part P lies in the guide groove 90. The component P that has passed through the outlet hole 110 moves in the movement path 76 to the component supply position PS described above while maintaining this normal posture.
　上記正規の姿勢ではなく、図５（ａ）において、Ｐ’で示すような姿勢で、部品Ｐが案内溝９０を移動させられることもあり得る。通常、そのような姿勢の部品Ｐ（以下、「立ち姿勢部品Ｐ’」と言う場合がある）は、出口穴１１０の箇所において、部品Ｐの溜まりに落下させられる。しかしながら、例えば、正規の姿勢の部品Ｐが直後に移動させられているような場合には、稀ではあるが、落下させられることなく、出口穴１１０の箇所において係止されることも予想される。そのようにして係止された立ち姿勢部品Ｐ’が存在する場合、後続の部品Ｐの移動経路７６への進入が阻害され、当該バルクフィーダ３０による部品Ｐの供給が停止させられることにもなりかねない。 It is possible that the component P is moved in the guide groove 90 in a posture as indicated by P ′ in FIG. 5A instead of the normal posture. Usually, the component P having such a posture (hereinafter, sometimes referred to as “standing posture component P ′”) is dropped in the pool of the component P at the exit hole 110. However, for example, in the case where the component P in a normal posture is moved immediately afterward, it is rarely expected that the component P is locked at the position of the outlet hole 110 without being dropped. . When there is a standing posture component P ′ that is locked in such a manner, the entry of the subsequent component P into the movement path 76 is inhibited, and the supply of the component P by the bulk feeder 30 is also stopped. It might be.
　そこで、上記立ち姿勢部品Ｐ’の姿勢を修正するために、バルクフィーダ３０では、案内溝９０の一部に、底面１０６が隆起して深さＤが小さくされた部分、つまり、底面隆起部１１２が設けられている。詳しく言えば、部品Ｐの溜まりの上方に位置する位置において、出口穴１１０の手前側において、出口穴１１０から磁石９６の配設角度ピッチの半分程度離れた位置に設けられている。 Therefore, in order to correct the posture of the standing posture component P ′, in the bulk feeder 30, a portion where the bottom surface 106 is raised and the depth D is reduced in a part of the guide groove 90, that is, the bottom surface raised portion 112. Is provided. More specifically, at the position located above the pool of the parts P, it is provided on the front side of the outlet hole 110 at a position that is separated from the outlet hole 110 by about half of the arrangement angle pitch of the magnets 96.
　出口穴１１０の箇所において係止された立ち姿勢部品Ｐ’が存在して、部品Ｐの供給が停止されているような場合には、例えば、磁石移動装置１０２によって、磁石９６を逆回転させればよい。図６（ａ）に示すように、磁石９６の逆回転によって、係止された立ち姿勢部品Ｐ’と後続の部品Ｐとが、案内溝９０に沿って、逆向きに移動させられ、図６（ｂ）に示すように、底面隆起部１１２にまで到達する。底面隆起部１１２の斜面に位置したときに、比較的不安定な立ち姿勢部品Ｐ’は、磁石９６の磁力によって倒されて、図６（ｃ）に示すように、正規の姿勢となる。その後、図６（ｄ）に示す位置から、磁石９６の正回転によって移動させれば、正規の姿勢となった部品Ｐおよびその後続の部品Ｐは、出口穴１１０を通過して、部品供給位置ＰＳに移動させられることになる。なお、図６（ａ）～（ｄ）に示すように、底面隆起部１１２においても案内溝９０は、ある程度の深さを有している。つまり、底面隆起部１１２においても、部品Ｐが１対の側面１０４において幅方向に挟まれている。そのことは、立ち姿勢部品Ｐ’を、案内溝９０内に正規の姿勢で嵌り込ませるのに役立っている。 In the case where there is a standing posture part P ′ locked at the exit hole 110 and supply of the part P is stopped, for example, the magnet 96 can be reversely rotated by the magnet moving device 102. That's fine. As shown in FIG. 6A, by the reverse rotation of the magnet 96, the locked standing posture component P ′ and the subsequent component P are moved in the reverse direction along the guide groove 90. As shown in (b), the bottom ridge 112 is reached. When positioned on the slope of the bottom raised portion 112, the relatively unstable standing posture component P ′ is brought down by the magnetic force of the magnet 96 and assumes a normal posture as shown in FIG. Thereafter, if the magnet 96 is moved from the position shown in FIG. 6 (d) by the normal rotation of the magnet 96, the component P and the subsequent component P in the normal posture pass through the outlet hole 110 and pass through the component supply position. It will be moved to PS. As shown in FIGS. 6A to 6D, the guide groove 90 also has a certain depth in the bottom raised portion 112. That is, also in the bottom raised portion 112, the component P is sandwiched between the pair of side surfaces 104 in the width direction. This is useful for fitting the standing posture component P ′ into the guide groove 90 in a normal posture.
　上記の説明は、係止された立ち姿勢部品Ｐ’が存在したことを前提に磁石９６を逆回転させる場合の説明であるが、立ち姿勢部品Ｐ’が係止される前に、磁石９６を逆回転させてその立ち姿勢部品Ｐ’を正規の姿勢にするようにしてもよい。また、磁石９６を逆回転させずとも、単に、立ち姿勢部品Ｐ’が正回転で底面隆起部１１２を通過することによっても、立ち姿勢部品Ｐ’の正規の姿勢への移行が期待できるのである。 The above description is for the case where the magnet 96 is reversely rotated on the assumption that the locked posture component P ′ is present. The standing posture component P ′ may be set to a normal posture by rotating in the reverse direction. In addition, even if the magnet 96 is not rotated in the reverse direction, the standing posture component P ′ can be expected to shift to the normal posture simply by passing the bottom raised portion 112 in the normal rotation. .
