　２．バルクフィーダ３０の構成
　バルクフィーダ３０は、部品装着機１０に装備されて部品供給装置１２の一部として機能する。バルクフィーダ３０は、キャリアテープのように包装されていないバルク状態で部品ケースに収容された部品９２を供給する。そのため、バルクフィーダ３０は、テープフィーダと異なりキャリアテープを用いないため、キャリアテープの装填や使用済みテープの回収などを省略できる点でメリットがある。 2. Configuration of bulk feeder 30 The bulk feeder 30 is installed in the component mounting machine 10 and functions as a part of the component supply device 12. The bulk feeder 30 supplies a component 92 housed in a component case in an unwrapped bulk state like a carrier tape. Therefore, unlike a tape feeder, the bulk feeder 30 does not use a carrier tape, and therefore has the advantage that loading of a carrier tape, collection of used tape, etc. can be omitted.
　バルクフィーダ３０には、例えば平面状の供給領域Ａｓに不規則な姿勢で部品９２を供給するタイプがある。しかしながら、供給領域Ａｓにおいて部品９２同士が接触するほど接近していたり堆積（上下方向に重なり合っている状態）していたり、部品９２の幅方向が上下方向となるような横立ち姿勢であったりすると、部品装着機１０は、これらの部品９２を採取対象にすることができない。そこで、採取可能な部品９２の割合を増加すべく、バルクフィーダ３０には、供給領域Ａｓにおいて部品９２を整列させた状態で供給するタイプがある。本実施形態では、部品９２を整列させるタイプのバルクフィーダ３０を例示して説明する。 For example, there is a type of bulk feeder 30 that supplies parts 92 in an irregular posture to a planar supply area As. However, if the parts 92 are so close that they touch each other in the supply area As, or are piled up (overlapping each other in the vertical direction), or if the parts 92 are in a horizontal position with the width direction being the vertical direction, , the component mounting machine 10 cannot collect these components 92. Therefore, in order to increase the proportion of the parts 92 that can be collected, there is a type of bulk feeder 30 that supplies the parts 92 in an aligned state in the supply area As. In this embodiment, a bulk feeder 30 of a type that aligns parts 92 will be described as an example.

The bulk feeder 30 includes a track member 34. The track member 34 is provided so as to be able to vibrate and to be detachably attached to the feeder main body 31 . The track member 34 is given vibration by a vibration device 41, which will be described later. The track member 34 is formed with a conveyance path R along which the plurality of parts 92 are conveyed, and a supply area As that communicates with the conveyance path R and opens upward so that the plurality of parts 92 can be collected.
　軌道部材３４は、フィーダ本体３１の前後方向（図３の左右方向）に延伸するように形成される。軌道部材３４の幅方向（図３の上下方向）の両縁には、上方に突出する一対の側壁３４１が形成される。一対の側壁３４１は、軌道部材３４の先端部３４２とともに搬送路Ｒの周縁を囲い、搬送路Ｒを搬送される部品９２の漏出を防止する。先端部３４２の上面には、供給領域Ａｓの基準位置を示す円形の基準マーク３４４が左右一対で付される。 The track member 34 is formed to extend in the front-back direction of the feeder main body 31 (the left-right direction in FIG. 3). A pair of side walls 341 that protrude upward are formed on both edges of the track member 34 in the width direction (vertical direction in FIG. 3). The pair of side walls 341 surround the periphery of the conveyance path R together with the tip end 342 of the track member 34, and prevent leakage of the component 92 conveyed through the conveyance path R. On the upper surface of the tip portion 342, a pair of left and right circular reference marks 344 indicating the reference position of the supply area As are attached.
　本実施形態において、軌道部材３４には、整列部材５０が交換可能に取り付けられる。整列部材５０は、複数の部品９２を個々に収容する複数のキャビティ５１を有する。複数のキャビティ５１のそれぞれは、上方に開口し、部品９２の厚み方向が上下方向となる姿勢で部品９２を収容する。整列部材５０における複数のキャビティ５１の配置の詳細については後述する。 In this embodiment, the alignment member 50 is replaceably attached to the track member 34. The alignment member 50 has a plurality of cavities 51 that individually accommodate a plurality of parts 92. Each of the plurality of cavities 51 opens upward and accommodates the component 92 in a posture such that the thickness direction of the component 92 is in the vertical direction. Details of the arrangement of the plurality of cavities 51 in the alignment member 50 will be described later.
　ここで、軌道部材３４の「供給領域Ａｓ」とは、部品９２をバルク状態で供給する領域であって、装着ヘッド１３３に支持された吸着ノズル１３４により部品９２を採取可能な領域である。また、軌道部材３４の「搬送路Ｒ」とは、部品ケース側から軌道部材３４へと流通した部品９２が供給領域Ａｓへと搬送される部品９２の通り道である。 Here, the "supply area As" of the track member 34 is an area where the component 92 is supplied in bulk, and is an area where the component 92 can be collected by the suction nozzle 134 supported by the mounting head 133. Further, the "conveyance path R" of the track member 34 is a path of the component 92 that has been distributed from the component case side to the track member 34 and is conveyed to the supply area As.

The bulk feeder 30 includes a shutter 37 provided above the track member 34 and capable of closing the opening of the supply area As. By opening and closing the shutter 37, the bulk feeder 30 can prevent parts 92 from flying out or foreign matter from entering the supply area As.
　シャッタ３７は、開閉動作により開状態、閉状態、および中間状態を切り換えられる。シャッタ３７の閉状態とは、シャッタ３７が軌道部材３４に接触し、供給領域Ａｓの開口が完全に閉塞された状態である。このとき、シャッタ３７は、図３の破線で示すように、軌道部材３４の一対の基準マーク３４４よりもフィーダ本体３１の後側に位置し、上方視において一対の基準マーク３４４を視認および撮像可能とする。 The shutter 37 can be switched between an open state, a closed state, and an intermediate state by opening and closing operations. The closed state of the shutter 37 is a state in which the shutter 37 contacts the track member 34 and the opening of the supply area As is completely closed. At this time, the shutter 37 is located on the rear side of the feeder main body 31 than the pair of reference marks 344 of the track member 34, as shown by the broken line in FIG. shall be.

Specifically, the vibration device 41 applies vibration to the track member 34 so that the plurality of components 92 are transported along the transport path R. When the vibration device 41 applies vibration to the track member 34, the track member 34 moves in an ellipse when viewed from the side.
　これにより、搬送路Ｒにある複数の部品９２は、軌道部材３４の楕円運動の回転方向に応じて前方且つ上方の外力、または後方且つ上方の外力を加えられる。結果として、複数の部品９２は、軌道部材３４の前側に搬送されたり、後側に搬送されたりすることになる。バルクフィーダ３０は、軌道部材３４に付与される振動の周波数や振幅、振動による楕円運動の回転方向の制御によって、搬送される部品９２の搬送速度、部品９２の分散度合い、および搬送方向などを変動させることができる。 As a result, a forward and upward external force or a backward and upward external force is applied to the plurality of components 92 on the conveyance path R, depending on the rotational direction of the elliptical motion of the track member 34.

Specifically, the conveyance operation includes a feed operation such that the component 92 located at the front end of the conveyance path R advances to the front end of the supply area As, and then the component 92 retreats to the front end of the conveyance path R again. This includes a return operation to the extent that
　なお、次回の採取動作の開始までに十分な時間的余裕がある場合には、搬送動作において、複数の部品９２を供給領域Ａｓにて前後方向に複数回に亘り往復させるように、送り動作および戻し動作を繰り返し実行するようにしてもよい。つまり、バルクフィーダ３０における部品の供給動作には、許容時間や採取可能数の確保などの事情を勘案して複数の搬送パターンから選択された一つを選択的に実行させることができる。 Note that if there is sufficient time before the start of the next sampling operation, the feeding operation and The return operation may be repeated. In other words, for the component feeding operation in the bulk feeder 30, one selected from a plurality of transport patterns can be selectively executed in consideration of circumstances such as allowable time and securing the number of parts that can be collected.
　３．整列部材５０における複数のキャビティ５１の配置
　３－１．整列部材５０の概要
　本実施形態のバルクフィーダ３０は、上記のようにバルク状態の部品９２を供給領域Ａｓにおいて複数のキャビティ５１に収容することによって、複数の部品９２を整列させた状態で供給する。複数のキャビティ５１は、軌道部材３４に取り付けられる整列部材５０にそれぞれ形成される。 3. Arrangement of multiple cavities 51 in alignment member 50 3-1. Overview of alignment member 50 The bulk feeder 30 of this embodiment supplies a plurality of components 92 in an aligned state by accommodating the components 92 in a bulk state in the plurality of cavities 51 in the supply area As as described above. . A plurality of cavities 51 are formed in each alignment member 50 attached to the track member 34 .
　キャビティ５１の開口は、平面視における部品９２の外形よりも僅かに大きくなる寸法に設定される。本実施形態において、部品９２の外形は、平面視において長方形状（長辺と短辺を有する角チップ形状）に形成されている。この部品９２を収容対象とするキャビティ５１は、部品９２の外形に倣った長方形状に形成される。 The opening of the cavity 51 is set to be slightly larger than the outer shape of the component 92 in plan view. In this embodiment, the outer shape of the component 92 is formed into a rectangular shape (a square chip shape having long sides and short sides) in a plan view. The cavity 51 that accommodates the component 92 is formed into a rectangular shape that follows the outer shape of the component 92.
　また、キャビティ５１の深さＴｖは、部品９２の種類（形状、質量など）に応じて設定される。本実施形態において、キャビティ５１の深さＴｖは、図５に示すように、部品９２の厚みＫｐよりも小さく設定される。軌道部材３４には、種々のタイプの軌道部材３４から、部品９２の種類や、キャビティ５１の必要数、機能性に基づいて選択された１つが取り付けられる。このとき、キャビティ５１の深さＴｖは、部品９２の厚みＫｐ以上に設定されることがある。 Further, the depth Tv of the cavity 51 is set according to the type (shape, mass, etc.) of the component 92. In this embodiment, the depth Tv of the cavity 51 is set smaller than the thickness Kp of the component 92, as shown in FIG. One of the various types of track members 34 selected based on the type of component 92, the required number of cavities 51, and functionality is attached to the track member 34. At this time, the depth Tv of the cavity 51 may be set to be greater than or equal to the thickness Kp of the component 92.
　ここで、バルクフィーダ３０による部品９２の供給動作において、フィーダ制御装置４２は、搬送装置としての加振装置４１を駆動させて、複数の部品９２の搬送動作を実行する。これにより、複数の部品９２の一部がキャビティ５１に収容され、戻し動作によってキャビティ５１に収容されなかった残りの部品９２が供給領域Ａｓから除去される。その後に、部品装着機１０の制御装置１６により供給状態の認識処理が実行される。 Here, in the operation of supplying the parts 92 by the bulk feeder 30, the feeder control device 42 drives the vibration device 41 as a transport device to carry out the operation of transporting the plurality of parts 92. As a result, some of the plurality of components 92 are accommodated in the cavity 51, and the remaining components 92 that are not accommodated in the cavity 51 are removed from the supply area As by the return operation. After that, the control device 16 of the component mounting machine 10 executes a supply state recognition process.
　詳細には、制御装置１６は、バルクフィーダ３０が部品９２の供給動作を実行した後に、供給領域Ａｓを対象とした基板カメラ１５の撮像により画像データＤ１（図６を参照）を取得する。図６は、画像データＤ１の一例である。このように、供給領域Ａｓには、バルク状態の部品９２が多数存在し、例えばキャビティ５１に正常な姿勢で収容されるもの、キャビティ５１の外部にあるもの、互いに接触したり堆積したりするもの、横立ち姿勢であるものなどが存在し得る。制御装置１６は、複数のキャビティ５１ごとに状態を割り出す。 Specifically, after the bulk feeder 30 executes the supply operation of the component 92, the control device 16 acquires image data D1 (see FIG. 6) by imaging the supply area As with the board camera 15. FIG. 6 is an example of the image data D1. In this way, there are many parts 92 in bulk in the supply area As, for example, parts accommodated in the cavity 51 in a normal posture, parts outside the cavity 51, parts that come into contact with each other or are piled up. There may also be cases where the user is in a sideways standing position. The control device 16 determines the state of each of the plurality of cavities 51.
　これにより、複数のキャビティ５１は、部品９２を採取可能に収容する収容キャビティ、周囲に部品９２が存在するものの採取不可であるＮＧキャビティ、周囲に部品９２が存在しない空キャビティに分類される。制御装置１６は、複数のキャビティ５１の各状態の数を算出する。このとき、複数のキャビティ５１の総数に対する収容キャビティの割合（充填率）が高いことが望ましい。これに対して、上記のように供給動作における部品９２の搬送パターンを適宜選択することに加えてまたは換えて、本実施形態のバルクフィーダ３０は、複数のキャビティ５１の配置により充填率を向上させることができる下記のような構成を採用する。 As a result, the plurality of cavities 51 are classified into accommodation cavities that accommodate parts 92 so that they can be collected, NG cavities that have parts 92 around them but cannot be collected, and empty cavities that have no parts 92 around them. The control device 16 calculates the number of states of the plurality of cavities 51. At this time, it is desirable that the ratio (filling rate) of accommodation cavities to the total number of cavities 51 is high. On the other hand, in addition to or in place of appropriately selecting the transport pattern of the parts 92 during the feeding operation as described above, the bulk feeder 30 of the present embodiment improves the filling rate by arranging the plurality of cavities 51. Adopt the following configuration that can be used.
　３－２．複数のキャビティ５１の配置の詳細
　本実施形態において、図４に示すように、複数のキャビティ５１は、供給領域Ａｓにおいて千鳥状に配置される。ここで、供給領域Ａｓにおいて第一方向Ｃ１に沿って配置された複数のキャビティ５１をキャビティ列Ｗｔとする。複数のキャビティ列Ｗｔが第一方向Ｃ１に交差する第二方向Ｃ２に並んで配置され、少なくとも一つのキャビティ列Ｗｔが隣り合う他のキャビティ列Ｗｔに対して第一方向Ｃ１に所定量シフトして配置される。 3-2. Details of Arrangement of Plurality of Cavities 51 In this embodiment, as shown in FIG. 4, the plurality of cavities 51 are arranged in a staggered manner in the supply area As. Here, the plurality of cavities 51 arranged along the first direction C1 in the supply area As are defined as a cavity row Wt. A plurality of cavity rows Wt are arranged side by side in a second direction C2 intersecting the first direction C1, and at least one cavity row Wt is shifted by a predetermined amount in the first direction C1 with respect to another adjacent cavity row Wt. Placed.
　本実施形態において、上記の第一方向Ｃ１は、軌道部材３４における部品９２の搬送方向Ｃｔの直交方向（図４の左右方向）であり、上記の第二方向Ｃ２は、搬送方向Ｃｔ（図４の上下方向）である。また、上記の所定量（以下、「シフト量Ｍａ」とも称する）は、複数のキャビティ５１が第一方向Ｃ１に沿って配置される第一間隔Ｐｔ１の半分の距離に設定される。そして、第二方向Ｃ２において複数のキャビティ列Ｗｔが交互にシフトして配置されることにより、複数のキャビティ５１が供給領域Ａｓにおいて千鳥状に配置される。 In the present embodiment, the first direction C1 is a direction perpendicular to the conveyance direction Ct of the component 92 in the track member 34 (the left-right direction in FIG. 4), and the second direction C2 is the conveyance direction Ct (the left-right direction in FIG. vertical direction). Moreover, the above-mentioned predetermined amount (hereinafter also referred to as "shift amount Ma") is set to a distance that is half the first interval Pt1 between which the plurality of cavities 51 are arranged along the first direction C1. Then, by alternately shifting and arranging the plurality of cavity rows Wt in the second direction C2, the plurality of cavities 51 are arranged in a staggered manner in the supply area As.
　換言すると、供給領域Ａｓにおいて搬送方向Ｃｔに隣り合うキャビティ列Ｗｔが互い違いになるジグザグ状に配置される。具体的には、整列部材５０には、搬送方向Ｃｔに８つのキャビティ列Ｗｔ１－Ｗｔ８が形成される。８つのキャビティ列Ｗｔ１－Ｗｔ８のうち搬送路Ｒ側（図４の下側）から奇数番目のキャビティ列Ｗｔ１，Ｗｔ３，Ｗｔ５，Ｗｔ７は、バルクフィーダ３０の幅方向（図４の左右方向）に等間隔（第一間隔Ｐｔ１）で配置された１２個のキャビティ５１で構成される。 In other words, in the supply area As, the cavity rows Wt adjacent to each other in the transport direction Ct are arranged in an alternating zigzag pattern. Specifically, eight cavity rows Wt1 to Wt8 are formed in the alignment member 50 in the conveyance direction Ct. Among the eight cavity rows Wt1 to Wt8, the odd-numbered cavity rows Wt1, Wt3, Wt5, and Wt7 from the transport path R side (lower side in FIG. 4) are arranged equally in the width direction of the bulk feeder 30 (left-right direction in FIG. 4). It is composed of 12 cavities 51 arranged at intervals (first interval Pt1).
　また、８つのキャビティ列Ｗｔ１－Ｗｔ８のうち搬送路Ｒ側（図４の下側）から偶数番目のキャビティ列Ｗｔ２，Ｗｔ４，Ｗｔ６，Ｗｔ８は、バルクフィーダ３０の幅方向（図４の左右方向）に等間隔（第一間隔Ｐｔ１）で配置された１１個のキャビティ５１で構成される。８つのキャビティ列Ｗｔ１－Ｗｔ８は、搬送方向Ｃｔである第二方向Ｃ２に等間隔（第二間隔Ｐｔ２）で配置される。結果として、バルクフィーダ３０は、規則的に配置された計９２個のキャビティ５１を有する。また、複数のキャビティ５１は、供給領域Ａｓにおいて長手方向が軌道部材３４における部品９２の搬送方向Ｃｔとなるように配置される。 Furthermore, among the eight cavity rows Wt1 to Wt8, the even-numbered cavity rows Wt2, Wt4, Wt6, and Wt8 from the transport path R side (lower side in FIG. 4) are arranged in the width direction of the bulk feeder 30 (left-right direction in FIG. 4). It is composed of 11 cavities 51 arranged at equal intervals (first interval Pt1). The eight cavity rows Wt1 to Wt8 are arranged at equal intervals (second interval Pt2) in the second direction C2, which is the conveyance direction Ct. As a result, the bulk feeder 30 has a total of 92 regularly arranged cavities 51. Further, the plurality of cavities 51 are arranged in the supply area As such that the longitudinal direction thereof corresponds to the transport direction Ct of the component 92 in the track member 34.
　ここで、バルクフィーダ３０の供給動作において、供給領域Ａｓを搬送方向Ｃｔに移動する部品９２は、既にキャビティ５１に収容された他の部品９２に接触すると、バルクフィーダ３０の幅方向へと回避しさらに搬送方向Ｃｔへと移動する（図４および図５の矢印）。このとき、複数のキャビティ５１が千鳥状に配置されていると、回避した部品９２の移動先にキャビティ５１が存在することになり、当該キャビティ５１への収容を促すことができる。 Here, in the supply operation of the bulk feeder 30, when the component 92 moving in the conveying direction Ct in the supply area As comes into contact with another component 92 already accommodated in the cavity 51, it avoids the component 92 in the width direction of the bulk feeder 30. It further moves in the transport direction Ct (arrow in FIGS. 4 and 5). At this time, if the plurality of cavities 51 are arranged in a staggered manner, the cavity 51 will exist at the destination of the avoided component 92, and accommodation in the cavity 51 can be encouraged.
　これは、複数のキャビティ５１をマトリックス状に配置（上記のシフト量Ｍａ＝０とした配置）した構成と比較すると、搬送路Ｒから搬送方向Ｃｔを見たときに供給領域Ａｓの幅方向で存在するキャビティ５１の列数が増加しているからとも言える。また、複数のキャビティ５１をマトリックス状に配置した構成では、キャビティ５１に既に収容された部品９２の上方を搬送中の部品９２が乗り越えさせるために振動を強く設定するなど調整が必要な場合がある。 When compared with a configuration in which a plurality of cavities 51 are arranged in a matrix (arrangement with the above shift amount Ma = 0), this exists in the width direction of the supply area As when looking at the transport direction Ct from the transport path R. This can also be said to be because the number of rows of cavities 51 is increasing. Furthermore, in a configuration in which a plurality of cavities 51 are arranged in a matrix, adjustments such as setting vibration to be strong may be necessary in order to cause the parts 92 being transported to overcome the parts 92 already accommodated in the cavities 51. .
　しかしながら、振動を強くすると、キャビティ５１に収容された部品９２が飛び出して、収容キャビティが減少する要因となり得る。これに対して、複数のキャビティ５１を千鳥状に配置した構成では、キャビティ５１から部品９２が飛び出さない程度の振動の強さであっても、当該部品９２を回避した部品９２がその搬送先のキャビティ５１への収容を促すことができる。これにより、供給動作における部品９２の搬送性を高めつつ、部品９２の充填率の向上を図ることができる。 However, if the vibration is strengthened, the parts 92 housed in the cavity 51 may fly out, which may cause the number of housing cavities to decrease. On the other hand, in a configuration in which a plurality of cavities 51 are arranged in a staggered manner, even if the vibration is strong enough to prevent a component 92 from popping out from the cavity 51, the component 92 that has avoided the component 92 will be transported to its destination. can be accommodated in the cavity 51. Thereby, it is possible to improve the filling rate of the parts 92 while improving the transportability of the parts 92 during the supply operation.
　４．実施形態の変形態様
　４－１．第一変形態様
　実施形態において、複数のキャビティ５１は、供給領域Ａｓにおいて長手方向が軌道部材３４における部品９２の搬送方向Ｃｔとなるように配置されるものとした。これに対して、キャビティ５１が収容の対象とする部品９２の外形が長方形状である場合に、複数のキャビティ５１のうち少なくとも一部について、長手方向が搬送方向Ｃｔと異なる方向となるように配置される構成としてもよい。 4. Variations of embodiment 4-1. First Modification In the embodiment, the plurality of cavities 51 are arranged such that the longitudinal direction thereof corresponds to the transport direction Ct of the component 92 in the track member 34 in the supply area As. On the other hand, when the outer shape of the component 92 to be housed in the cavity 51 is rectangular, at least some of the plurality of cavities 51 are arranged so that the longitudinal direction is in a direction different from the conveyance direction Ct. It is also possible to have a configuration in which
　例えば、第一変形態様において、図７に示すように、８つのキャビティ列Ｗｔ１－Ｗｔ８のうち搬送路Ｒ側から偶数番目のキャビティ列Ｗｔ２，Ｗｔ４，Ｗｔ６，Ｗｔ８を構成する複数のキャビティ５１は、長手方向が搬送方向Ｃｔに直交する方向（第一方向Ｃ１）となるように配置される。このような構成においても実施形態と同様の効果を奏する。 For example, in the first modification, as shown in FIG. 7, the plurality of cavities 51 forming the even-numbered cavity rows Wt2, Wt4, Wt6, and Wt8 from the transport path R side among the eight cavity rows Wt1 to Wt8 are as follows. It is arranged so that its longitudinal direction is perpendicular to the conveyance direction Ct (first direction C1). Such a configuration also provides the same effects as the embodiment.
　４－２．第二変形態様
　実施形態において、隣り合うキャビティ列Ｗｔのシフト量Ｍａは、第一間隔Ｐｔ１の半分の距離に設定されるものとした。これに対して、隣り合うキャビティ列Ｗｔのシフト量Ｍａは、第一間隔Ｐｔ１の半分の距離とは異なる距離に設定されてもよい。例えば、シフト量Ｍａは、図８に示すように、第一間隔Ｐｔ１の１／３に設定され、３つのキャビティ列Ｗｔ１－Ｗｔ３で１周期となるようにキャビティ列Ｗｔをそれぞれシフトしてもよい。このような構成においても実施形態と同様の効果を奏する。 4-2. Second Modification In the embodiment, the shift amount Ma of the adjacent cavity rows Wt is set to a distance that is half the first interval Pt1. On the other hand, the shift amount Ma of the adjacent cavity rows Wt may be set to a distance different from the half distance of the first interval Pt1. For example, as shown in FIG. 8, the shift amount Ma may be set to 1/3 of the first interval Pt1, and the cavity rows Wt may be shifted so that three cavity rows Wt1-Wt3 form one period. . Such a configuration also provides the same effects as the embodiment.
　４－３．その他の変形態様
　実施形態において、第一方向Ｃ１が搬送方向Ｃｔの直交方向であり、第二方向Ｃ２が搬送方向Ｃｔであるものとした。これに対して、第一方向Ｃ１に対して第二方向Ｃ２が交差する方向であれば、第一方向Ｃ１および第二方向Ｃ２は、種々の方向に設定することができる。また、複数のキャビティ列Ｗｔが交互にシフトして配置されるものとした。これに対して、複数のキャビティ列Ｗｔのうち少なくとも１つが隣り合う別のキャビティ列に対して所定量シフトして配置される構成であれば、実施形態と同様の効果を奏する。 4-3. Other Modifications In the embodiment, the first direction C1 is a direction orthogonal to the conveyance direction Ct, and the second direction C2 is the conveyance direction Ct. On the other hand, as long as the second direction C2 intersects the first direction C1, the first direction C1 and the second direction C2 can be set in various directions. Further, the plurality of cavity rows Wt are arranged in an alternately shifted manner. On the other hand, if at least one of the plurality of cavity rows Wt is arranged shifted by a predetermined amount with respect to another adjacent cavity row, the same effects as in the embodiment can be achieved.
　また、第一および第二変形態様、並びに第一方向Ｃ１、第二方向Ｃ２、およびシフトして配置するキャビティ列について適宜組み合わせて、複数のキャビティ５１を配置することもできる。そして、部品９２の種類や加振装置４１による振動に応じた搬送パターンに適用した種々の整列部材５０を用意し、これらから選択された１つが軌道部材３４に取り付けられる構成としてもよい。但し、供給領域Ａｓにおけるキャビティ５１の数を多くし、且つ充填率を向上させる観点からは、実施形態にて例示した態様が好適である。 Furthermore, a plurality of cavities 51 can be arranged by appropriately combining the first and second modified modes, the first direction C1, the second direction C2, and the shifted cavity rows. Then, a configuration may be adopted in which various alignment members 50 are prepared that are adapted to conveyance patterns depending on the type of component 92 and the vibration caused by the vibration excitation device 41, and one selected from these is attached to the track member 34. However, from the viewpoint of increasing the number of cavities 51 in the supply area As and improving the filling rate, the mode illustrated in the embodiment is preferable.
　また、実施形態において、バルクフィーダ３０は、軌道部材３４に整列部材５０が着脱可能に取り付けられることにより複数のキャビティ５１を備えるものとした。これに対して、バルクフィーダ３０は、軌道部材３４に複数のキャビティ５１が直接的に形成される構成としてもよい。つまり、整列部材は、軌道部材３４に一体的に形成される構成としてもよい。このような構成において、フィーダ本体３１に対して着脱可能に設けられる軌道部材３４は、複数のキャビティ５１によりバルク状態の部品９２を整列させる機能を有する一種の整列部材である。 Furthermore, in the embodiment, the bulk feeder 30 is provided with a plurality of cavities 51 by detachably attaching the alignment member 50 to the track member 34. On the other hand, the bulk feeder 30 may have a configuration in which the plurality of cavities 51 are directly formed in the track member 34. That is, the alignment member may be formed integrally with the track member 34. In such a configuration, the track member 34 that is detachably attached to the feeder main body 31 is a type of alignment member that has a function of aligning the bulk components 92 using the plurality of cavities 51 .
　実施形態において、搬送路Ｒと供給領域Ａｓとの間で複数の部品９２を搬送する搬送装置は、複数の部品９２を搬送するように軌道部材３４に振動を付与する加振装置４１であるものとした。これに対して、搬送装置は、種々の態様を採用し得る。例えば、搬送装置は、加振装置４１に加えてまたは換えて、磁力を用いて部品９２を搬送し、またはキャビティ５１に収容された部品９２を固定する構成としてもよい。その他に、搬送装置は、軌道部材３４を傾斜させる傾斜装置、供給領域Ａｓを摺動して複数の部品９２を移動させるブラシを備える構成としてもよい。 In the embodiment, the conveyance device that conveys the plurality of parts 92 between the conveyance path R and the supply area As is an excitation device 41 that applies vibration to the track member 34 so as to convey the plurality of parts 92. And so. On the other hand, the conveyance device can adopt various modes. For example, in addition to or in place of the vibration device 41, the transport device may be configured to use magnetic force to transport the component 92 or to fix the component 92 housed in the cavity 51. In addition, the conveying device may include a tilting device that tilts the track member 34 and a brush that slides on the supply area As to move the plurality of components 92.
　実施形態において、バルクフィーダ３０は、部品装着機１０により基板９１に装着される部品９２を供給する。実施形態において、上記の部品９２として、厚み方向から視たときに矩形をなすチップ部品を例示した。これに対して、部品９２は、部品装着機１０のように基板９１に所定の作業を実行する対基板作業機において用いられるものであり、バルクフィーダ３０においてキャビティ５１に収容した状態で供給可能な物品であれば種々のものを適用できる。例えば、バルクフィーダ３０は、球状に形成されたはんだボールを供給してもよい。この場合において、複数のキャビティ５１は、球状のはんだボールを収容可能な円筒凹状または半球凹状に形成される。 In the embodiment, the bulk feeder 30 supplies the components 92 to be mounted on the substrate 91 by the component mounting machine 10. In the embodiment, a chip component having a rectangular shape when viewed from the thickness direction is exemplified as the component 92. On the other hand, the component 92 is used in a board-to-board work machine that performs a predetermined work on the board 91, such as the component mounting machine 10, and can be supplied while being accommodated in the cavity 51 in the bulk feeder 30. Various articles can be applied. For example, the bulk feeder 30 may supply spherical solder balls. In this case, the plurality of cavities 51 are formed in a cylindrical concave shape or a hemispherical concave shape capable of accommodating spherical solder balls.
