Description

フィーダの取付構造Feeder mounting structure
　本発明は、電子部品実装機のフィーダ載置台にフィーダを着脱可能に取り付けるフィーダの取付構造に関する発明である。 The present invention relates to a feeder mounting structure in which a feeder is detachably mounted on a feeder mounting table of an electronic component mounting machine.
　一般に、フィーダの取付構造は、特許文献１（特開２００８－１３０８５１号公報）に記載されているように、フィーダの下面側のガイドレールを電子部品実装機のフィーダ載置台のガイド溝に差し込んで、フィーダの前端部に設けられた位置決めピンをフィーダ載置台の奥壁の位置決め孔に挿入してフィーダの前端部を位置決めしながら、フィーダの前端部のコネクタをフィーダ載置台の奥壁のコネクタに接続した状態で、フィーダに設けられたクランプ部材によってフィーダを前方（フィーダ載置台の奥壁）へ押し付けてクランプすることで、フィーダをフィーダ載置台に着脱可能に取り付けるようにしている。 Generally, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2008-130551), the feeder mounting structure is such that the guide rail on the lower surface side of the feeder is inserted into the guide groove of the feeder mounting table of the electronic component mounting machine. While inserting the positioning pin provided at the front end of the feeder into the positioning hole on the back wall of the feeder mounting table to position the front end of the feeder, the connector at the front end of the feeder is connected to the connector on the back wall of the feeder mounting table. In a connected state, the feeder is detachably attached to the feeder mounting table by pressing the feeder forward (back wall of the feeder mounting table) and clamping with a clamp member provided on the feeder.

　上記特許文献１のフィーダの取付構造では、クランプ部材によってフィーダを前方へ押し付けることで、フィーダを前後方向に位置決めできるが、フィーダの左右方向の位置決めに関しては、フィーダの下面側のガイドレールをフィーダ載置台のガイド溝に差し込むだけであるため、ガイドレール側面とガイド溝の縁部との間の遊び（隙間）の範囲内でフィーダの左右方向の位置ずれが生じ、このフィーダの左右方向の位置ずれが電子部品実装機の吸着ノズルの部品吸着位置の左右方向の位置ずれとなり、これが吸着ノズルの部品吸着動作の安定性を低下させる一因となる。近年の電子部品の微小化に伴ってフィーダの左右方向の位置ずれ（部品吸着位置の左右方向の位置ずれ）を小さくする必要がある。 In the feeder mounting structure of Patent Document 1 described above, the feeder can be positioned in the front-rear direction by pressing the feeder forward by the clamp member. However, for the left-right positioning of the feeder, the guide rail on the lower surface side of the feeder is mounted on the feeder. Since it is only inserted into the guide groove of the mounting table, the lateral displacement of the feeder occurs within the range of play (gap) between the side surface of the guide rail and the edge of the guide groove, and the lateral displacement of this feeder This is a lateral displacement of the component suction position of the suction nozzle of the electronic component mounting machine, which is a cause of lowering the stability of the component suction operation of the suction nozzle. With recent miniaturization of electronic components, it is necessary to reduce the lateral displacement of the feeder (the lateral displacement of the component suction position).
　この対策として、ガイドレール側面とガイド溝の縁部との間の遊びを小さくすることが考えられるが、この遊びを小さくすると、フィーダの着脱時にガイドレールをガイド溝に沿ってスライド移動させる際に、ガイドレール側面に作用する摩擦抵抗力が増大してフィーダの着脱作業性が悪くなる。従って、フィーダの着脱作業性を確保するには、ガイドレール側面とガイド溝の縁部との間の遊び量をある程度確保する必要がある。 As a countermeasure, it is conceivable to reduce the play between the side surface of the guide rail and the edge of the guide groove, but if this play is reduced, the guide rail is moved along the guide groove when the feeder is attached or detached. The frictional resistance acting on the side surface of the guide rail is increased, and the attachment / detachment workability of the feeder is deteriorated. Therefore, in order to ensure the attachment / detachment workability of the feeder, it is necessary to secure a certain amount of play between the side surface of the guide rail and the edge of the guide groove.
　また、特許文献２（特開２００９－１５８５５７号公報）に記載されているように、フィーダの下面側に２つの位置決めピンを下方に突出させて設けると共に、フィーダ載置台に２つの位置決め穴を設け、電子部品実装機のフィーダ載置台にフィーダを取り付ける際に、フィーダの２つの位置決めピンをフィーダ載置台の２つの位置決め穴に差し込むことで、フィーダの左右方向の位置ずれを防止するようにしたものがある。 Further, as described in Patent Document 2 (Japanese Patent Laid-Open No. 2009-158557), two positioning pins are provided on the lower surface side of the feeder so as to protrude downward, and two positioning holes are provided in the feeder mounting table. When the feeder is mounted on the feeder mounting table of the electronic component mounting machine, the two positioning pins of the feeder are inserted into the two positioning holes of the feeder mounting table to prevent the lateral displacement of the feeder. There is.
　しかし、上記特許文献２の技術では、フィーダの下面側に位置決めピンが下方に突出した状態で固定されているため、フィーダの着脱時にフィーダ載置台上でフィーダをスライド移動させる際に、フィーダから下方に突出した位置決めピンがスライド移動の邪魔になって、フィーダをスムーズにスライド移動させることが困難になり、フィーダの着脱作業性が悪化するという欠点がある。 However, in the technique of Patent Document 2, since the positioning pin is fixed to the lower surface side of the feeder so as to protrude downward, when the feeder is slid on the feeder mounting table when the feeder is attached or detached, the feeder is moved downward from the feeder. The positioning pins projecting in the way obstruct the sliding movement, making it difficult to smoothly slide the feeder and deteriorating the detachability of the feeder.
　そこで、本発明が解決しようとする課題は、フィーダの着脱作業性を確保しながら、フィーダ取付時のフィーダの左右方向の位置精度を向上できるフィーダの取付構造を提供することにある。 Therefore, the problem to be solved by the present invention is to provide a feeder mounting structure that can improve the position accuracy of the feeder in the left-right direction when the feeder is mounted while ensuring the detachability of the feeder.
　上記課題を解決するために、本発明は、フィーダの下面側のガイドレールを、電子部品実装機のフィーダ載置台のガイド溝に差し込んで、前記フィーダに設けられたクランプ部材によって前記フィーダを前方へ押し付けてクランプすることで、前記フィーダを前記フィーダ載置台に前後方向に位置決めして着脱可能に取り付けるフィーダの取付構造において、前記フィーダの左右方向の位置決めをする位置決め部材を、前記フィーダに移動可能に設けると共に、前記位置決め部材を前記フィーダから下方に突出させて前記フィーダ載置台の嵌合部に嵌まり込ませて前記フィーダの左右方向の位置決めをする突出位置と、前記位置決め部材を前記嵌合部から上方に抜き出して退避させる退避位置との間を移動させる操作部材を設けた構成としたものである。 In order to solve the above-mentioned problems, the present invention inserts a guide rail on the lower surface side of a feeder into a guide groove of a feeder mounting table of an electronic component mounting machine, and moves the feeder forward by a clamp member provided on the feeder. By pressing and clamping, in the feeder mounting structure in which the feeder is positioned on the feeder mounting table in the front-rear direction and detachably attached, a positioning member for positioning the feeder in the left-right direction can be moved to the feeder. A positioning position for projecting the positioning member downward from the feeder to be fitted into a fitting portion of the feeder mounting table to position the feeder in the left-right direction; and the positioning member for the fitting portion. An operation member that moves between the retraction position that is extracted upward from the retraction position is provided. It is intended.
　この構成では、電子部品実装機のフィーダ載置台にフィーダを取り付けるときに、クランプ部材によってフィーダを前方へ押し付けてクランプすると共に、位置決め部材を突出位置に移動させてフィーダ載置台の嵌合部に嵌め込むことで、フィーダを前後方向及び左右方向に位置決めした状態に取り付けることができる。これにより、フィーダの左右方向の位置精度（部品吸着位置の左右方向の位置精度）を向上できて、吸着ノズルの部品吸着動作の安定性を向上できる。しかも、フィーダの着脱時には、位置決め部材をフィーダ載置台の嵌合部から上方に抜き出して退避位置に退避させることで、位置決め部材がフィーダ着脱時のスライド移動の邪魔にならず、フィーダをスムーズにスライド移動させることができて、フィーダの着脱作業性を損なうことがない。 In this configuration, when the feeder is attached to the feeder mounting table of the electronic component mounting machine, the clamp member pushes the feeder forward and clamps it, and the positioning member is moved to the protruding position and fitted into the fitting portion of the feeder mounting table. By inserting the feeder, the feeder can be attached in a state of being positioned in the front-rear direction and the left-right direction. Thereby, the position accuracy in the left-right direction of the feeder (position accuracy in the left-right direction of the component suction position) can be improved, and the stability of the component suction operation of the suction nozzle can be improved. Moreover, when the feeder is attached or detached, the positioning member is pulled out from the fitting portion of the feeder mounting table and retracted to the retracted position, so that the positioning member does not interfere with the sliding movement when the feeder is attached or detached, and the feeder slides smoothly. It can be moved, and the attachment / detachment workability of the feeder is not impaired.
　この場合、クランプ部材は、フィーダを前方へ押し付けるクランプ位置と、フィーダの前方への押し付けを解除するアンクランプ位置との間を移動可能に設けられ、位置決め部材の移動を操作する操作手段は、クランプ部材の移動を操作する手段を兼用し、クランプ部材がクランプ位置に移動する動作に連動して位置決め部材が突出位置に移動し、クランプ部材がアンクランプ位置に移動する動作に連動して位置決め部材が退避位置に移動するように構成すると良い。このようにすれば、フィーダの着脱時に、作業者が１つの操作部材を操作するだけで、クランプ部材と位置決め部材の両方を適正な位置に移動させることができて、作業者がクランプ部材と位置決め部材を別々に操作する手間を省くことができ、フィーダの着脱作業性を更に向上できると共に、位置決め部材の誤操作を防止できる。 In this case, the clamp member is provided so as to be movable between a clamp position for pressing the feeder forward and an unclamp position for releasing the forward press of the feeder, and the operation means for operating the movement of the positioning member is a clamp. The positioning member moves to the protruding position in conjunction with the movement of the clamp member to the clamping position, and the positioning member moves in conjunction with the movement of the clamping member to the unclamping position. It may be configured to move to the retracted position. In this way, when the feeder is attached or detached, the operator can move both the clamp member and the positioning member to an appropriate position simply by operating one operation member, and the operator can position the clamp member and the positioning member. It is possible to save the trouble of separately operating the members, to further improve the attaching / detaching workability of the feeder and to prevent the positioning member from being erroneously operated.
　本発明は、フィーダ載置台に、位置決め部材を嵌まり込ませる嵌合部をガイド溝とは別に形成しても良いが、フィーダ載置台のガイド溝の一部を、位置決め部材を嵌まり込ませる嵌合部として使用するようにしても良い。このようにすれば、フィーダ載置台に位置決め部材用の嵌合部を新たに形成する必要がなく、従来と同様のフィーダ載置台に対しても、そのまま本発明を実施できる。 In the present invention, the fitting portion for fitting the positioning member into the feeder mounting table may be formed separately from the guide groove, but the positioning member is fitted into a part of the guide groove of the feeder mounting table. You may make it use it as a fitting part. In this way, it is not necessary to newly form a fitting portion for the positioning member on the feeder mounting table, and the present invention can be directly applied to a feeder mounting table similar to the conventional one.
　また、クランプ部材によってフィーダが前方（フィーダ載置台の奥壁）へ押し付けられてフィーダの前端部が位置決めされるため、フィーダの前端部を支点にしてフィーダの後端部側がガイドレール側面とガイド溝の縁部との間の遊びの範囲内で左右方向に位置ずれしやすいという特性を考慮して、フィーダのうちのフィーダ載置台に載置される部分の前後方向の中央よりも後側に位置決め部材を配置するようにすると良い。このようにすれば、フィーダの前端部側と位置決め部材とによってフィーダの前後方向及び左右方向の位置決め状態を安定して保持できる。 In addition, since the feeder is pressed forward (back wall of the feeder mounting table) by the clamp member and the front end of the feeder is positioned, the rear end of the feeder is the guide rail side surface and the guide groove with the front end of the feeder as a fulcrum. In consideration of the characteristic of being easily displaced in the left-right direction within the range of play with the edge of the feeder, the position of the part of the feeder that is mounted on the feeder mounting table is positioned behind the center in the front-rear direction It is preferable to arrange the members. If it does in this way, the positioning state of the front-back direction of a feeder and the left-right direction can be stably hold | maintained by the front-end part side and positioning member of a feeder.

In place of the mechanically connected connectors 16 and 17, a non-contact communication interface capable of non-contact communication or a non-contact power supply interface capable of non-contact power supply may be used.
　また、フィーダ１３の前端部のうちのコネクタ１６の上下両側には、コネクタ１６，１７の差し込み接続を案内するためのガイドピン４１，４２が設けられ、フィーダ載置台１４上に載置したフィーダ１３の各ガイドピン４１，４２が該フィーダ載置台１４の奥壁１４ａの位置決め孔４３，４４に嵌まり込むことで、フィーダ載置台１４上でフィーダ１３の前端部が位置決めされるようになっている。 In addition, guide pins 41 and 42 for guiding insertion and connection of the connectors 16 and 17 are provided on both the upper and lower sides of the connector 16 in the front end portion of the feeder 13, and the feeder 13 placed on the feeder placing table 14. By inserting the guide pins 41 and 42 into the positioning holes 43 and 44 of the back wall 14a of the feeder mounting table 14, the front end of the feeder 13 is positioned on the feeder mounting table 14. .
　フィーダ載置台１４の上面には、フィーダ１３を縦置き支持するための断面逆Ｔ字溝形のガイド溝１８（図４参照）が設けられ、フィーダ１３の下面側に設けられた断面逆Ｔ字形のガイドレール１９を手前側からガイド溝１８に差し込むことで、フィーダ載置台１４上にフィーダ１３が縦置き状態に支持されると共に、該フィーダ１３に設けられたクランプ部材２１がフィーダ載置台１４のクランプ穴２２に嵌まり込んで該フィーダ１３を前方（フィーダ載置台１４の奥壁１４ａ側）へ押し付けてクランプすることで、該フィーダ１３をフィーダ載置台１４上に前後方向に位置決めして着脱可能に取り付けるようになっている。 A guide groove 18 (see FIG. 4) having an inverted T-shaped cross section for vertically supporting the feeder 13 is provided on the upper surface of the feeder mounting table 14, and an inverted T-shaped cross section provided on the lower surface side of the feeder 13. When the guide rail 19 is inserted into the guide groove 18 from the front side, the feeder 13 is supported on the feeder mounting table 14 in a vertically placed state, and the clamp member 21 provided on the feeder 13 is connected to the feeder mounting table 14. The feeder 13 is positioned in the front-rear direction on the feeder mounting table 14 and can be attached / detached by fitting into the clamp hole 22 and pressing the feeder 13 forward (on the rear wall 14a side of the feeder mounting table 14) and clamping. It is supposed to be attached to.
　図２及び図３に示すように、クランプ部材２１は、軸２０を支点にして回動するレバー２３の一端に軸２４を介して回動可能に連結され、該レバー２３の他端には、軸２５を介してリンク２６が回動可能に連結されている。リンク２６は、フィーダ１３の上部手前側
に設けられた操作部材である操作レバー２７（図１参照）の操作に連動して左右方向に移動し、それに連動して、レバー２３が軸２０を支点にして回動してクランプ部材２１を上下動させるようになっている。これにより、操作レバー２７をクランプ位置（図１の実線の位置）に操作すると、図２に示すように、クランプ部材２１がフィーダ載置台１４のクランプ穴２２に嵌まり込んでフィーダ１３を前方（フィーダ載置台１４の奥壁１４ａ側）へ押し付けてクランプした状態となり、操作レバー２７をアンクランプ位置（図１の二点鎖線の位置）に操作すると、図３に示すように、クランプ部材２１がクランプ穴２２から斜め上方に引き上げられてクランプ状態（フィーダ１３の前方への押し付け状態）を解除したアンクランプ状態となる。 2 and 3, the clamp member 21 is rotatably connected to one end of a lever 23 that rotates about a shaft 20 via a shaft 24, and the other end of the lever 23 is connected to the other end of the lever 23. A link 26 is rotatably connected via a shaft 25. The link 26 moves in the left-right direction in conjunction with the operation of an operation lever 27 (see FIG. 1) that is an operation member provided on the upper front side of the feeder 13, and in conjunction with this, the lever 23 supports the shaft 20 as a fulcrum. And the clamp member 21 is moved up and down. Accordingly, when the operation lever 27 is operated to the clamp position (the position indicated by the solid line in FIG. 1), as shown in FIG. 2, the clamp member 21 is fitted into the clamp hole 22 of the feeder mounting table 14 and the feeder 13 is moved forward ( When the operation lever 27 is operated to the unclamping position (the position indicated by the two-dot chain line in FIG. 1), the clamp member 21 is moved to the unclamping position (the position indicated by the two-dot chain line in FIG. 1). The unclamped state is released in which the clamped state (the state of pressing the feeder 13 forward) is lifted obliquely upward from the clamp hole 22.
　クランプ部材２１、レバー２３、リンク２６の少なくとも１つには、クランプ部材２１をクランプ方向（斜め下方）に付勢するためのばね等の付勢手段（図示せず）が設けられ、この付勢手段の付勢力によってクランプ状態が保持されるようになっている。クランプ部材２１には、該クランプ部材２１の移動方向を斜め上下方向に規制する長孔２９が形成され、この長孔２９がガイド軸３０に嵌まり込むことで、クランプ部材２１の移動方向が斜め上下方向に規制されている。 At least one of the clamp member 21, the lever 23, and the link 26 is provided with a biasing means (not shown) such as a spring for biasing the clamp member 21 in the clamping direction (diagonally downward). The clamp state is held by the biasing force of the means. The clamp member 21 is formed with a long hole 29 that regulates the moving direction of the clamp member 21 in a slanting vertical direction. The long hole 29 is fitted into the guide shaft 30 so that the moving direction of the clamp member 21 is slanted. It is regulated in the vertical direction.
　レバー２３の近傍には、クランプ／アンクランプの切り換えを検出する安全スイッチ３１が設けられ、図２に示すように、クランプ部材２１がフィーダ載置台１４のクランプ穴２２に嵌まり込んだクランプ状態になると、レバー２３が安全スイッチ３１のアクチュエータ３２を押し込んで該安全スイッチ３１がオン状態（検出状態）に切り換えられ、図３に示すように、クランプ部材２１がクランプ穴２２から斜め上方に引き上げられてアンクランプ状態となると、レバー２３が安全スイッチ３１のアクチュエータ３２から離れて該安全スイッチ３１がオフ状態（非検出状態）に切り換えられる。これにより、フィーダ１３の制御部及び／又は電子部品実装機の制御部が安全スイッチ３１がオンかオフかを判別することで、クランプ状態かアンクランプ状態かを判別できるようになっている。 In the vicinity of the lever 23, a safety switch 31 for detecting switching between clamping and unclamping is provided. As shown in FIG. 2, the clamping member 21 is in a clamping state in which the clamping member 21 is fitted in the clamping hole 22 of the feeder mounting table 14. Then, the lever 23 pushes the actuator 32 of the safety switch 31 to switch the safety switch 31 to the ON state (detection state), and the clamp member 21 is lifted obliquely upward from the clamp hole 22 as shown in FIG. In the unclamped state, the lever 23 is separated from the actuator 32 of the safety switch 31, and the safety switch 31 is switched to the off state (non-detection state). As a result, the control unit of the feeder 13 and / or the control unit of the electronic component mounting machine can determine whether the safety switch 31 is on or off, thereby determining whether it is in the clamped state or the unclamped state.
　フィーダ１３には、該フィーダ１３の左右方向の位置決めをする位置決めピン３３（位置決め部材）がクランプ部材２１の近傍に上下動可能に設けられている。この位置決めピン３３は、下向きに固定されたスプリングプランジャ３４のロッド３５に連結され、該スプリングプランジャ３４内部のスプリング（図示せず）によって下方に付勢されている。位置決めピン３３の上部（又はスプリングプランジャ３４のロッド３５）には、係合フランジ３６が設けられ、クランプ部材２１に形成された係合片３７が係合フランジ３６に下側から係合することで、クランプ部材２１の上下動と連動して位置決めピン３３が上下動するようになっている。位置決めピン３３は、円柱状であっても良いし、断面四角形等の角柱状の部材で形成したものであっても良い。 The feeder 13 is provided with positioning pins 33 (positioning members) for positioning the feeder 13 in the left-right direction so as to be movable up and down in the vicinity of the clamp member 21. The positioning pin 33 is connected to a rod 35 of a spring plunger 34 fixed downward, and is biased downward by a spring (not shown) inside the spring plunger 34. An engagement flange 36 is provided on the upper portion of the positioning pin 33 (or the rod 35 of the spring plunger 34), and an engagement piece 37 formed on the clamp member 21 is engaged with the engagement flange 36 from below. The positioning pin 33 moves up and down in conjunction with the up and down movement of the clamp member 21. The positioning pin 33 may be cylindrical or may be formed of a prismatic member such as a quadrangular section.
　本発明は、フィーダ載置台１４に、位置決めピン３３を嵌まり込ませる嵌合部をガイド溝１８とは別に形成しても良いが、本実施例では、フィーダ載置台１４のガイド溝１８の一部を、位置決めピン３３を嵌まり込ませる嵌合部として使用するようにしている。 In the present invention, a fitting portion for fitting the positioning pin 33 into the feeder mounting table 14 may be formed separately from the guide groove 18, but in this embodiment, one of the guide grooves 18 of the feeder mounting table 14 is formed. The portion is used as a fitting portion into which the positioning pin 33 is fitted.
　図２に示すように、クランプ部材２１がクランプ位置に下降する際に、それまで位置決めピン３３の係合フランジ３６を押し上げていたクランプ部材２１の係合片３７も下降するため、スプリングプランジャ３４内部のスプリングによって位置決めピン３３が下方の突出位置まで押し下げられてガイド溝１８に嵌まり込んだ状態になる（図４参照）。位置決めピン３３の下端部は、ガイド溝１８に嵌まり込みやすいようにテーパ状に形成されている。 As shown in FIG. 2, when the clamp member 21 is lowered to the clamp position, the engagement piece 37 of the clamp member 21 that has been pushing up the engagement flange 36 of the positioning pin 33 is also lowered, so that the inside of the spring plunger 34 As a result, the positioning pin 33 is pushed down to the lower protruding position and is fitted into the guide groove 18 (see FIG. 4). The lower end portion of the positioning pin 33 is formed in a tapered shape so as to be easily fitted into the guide groove 18.
　図４に示すように、位置決めピン３３の直径は、ガイド溝１８の開口幅（溝幅）よりも僅かに小さく且つガイドレール１９の厚み寸法よりも大きく形成されている。これにより
、位置決めピン３３がガイド溝１８に嵌まり込んだ状態になると、位置決めピン３３とガイド溝１８の縁部との間の遊び（隙間）が、ガイドレール１９側面とガイド溝１８の縁部との間の遊びよりも小さくなり、フィーダ１３の左右方向の位置決めがなされる。この状態では、フィーダ１３に左右方向から外力が作用しても、フィーダ１３の左右方向の位置ずれ（部品吸着位置の左右方向の位置ずれ）が小さくなり、部品吸着位置の左右方向の位置精度が向上する。 As shown in FIG. 4, the diameter of the positioning pin 33 is slightly smaller than the opening width (groove width) of the guide groove 18 and larger than the thickness dimension of the guide rail 19. As a result, when the positioning pin 33 is fitted into the guide groove 18, the play (gap) between the positioning pin 33 and the edge of the guide groove 18 causes the side surface of the guide rail 19 and the edge of the guide groove 18. Thus, the feeder 13 is positioned in the left-right direction. In this state, even if an external force is applied to the feeder 13 from the left-right direction, the lateral displacement of the feeder 13 (the lateral displacement of the component suction position) is reduced, and the lateral accuracy of the component suction position is improved. improves.
　位置決めピン３３の位置は、フィーダ載置台１４のガイド溝１８の上方であれば、どの位置であっても良いが、本実施例では、フィーダ１３のうちのフィーダ載置台１４に載置される部分の前後方向の中央よりも後側に位置決めピン３３を配置している。この理由は、クランプ部材２１によってフィーダ１３が前方（フィーダ載置台１４の奥壁１４ａ）へ押し付けられてフィーダ１３の前端部がガイドピン４１，４２で位置決めされるため、フィーダ１３の前端部を支点にしてフィーダ１３の後端部側がガイドレール１９側面とガイド溝１８の縁部との間の遊びの範囲内で左右方向に位置ずれしやすいという特性を考慮したものである。従って、フィーダ１３のうちのフィーダ載置台１４に載置される部分の前後方向の中央よりも後側に位置決めピン３３を配置すれば、フィーダ１３の前端部側と後側の位置決めピン３３とによってフィーダの前後方向及び左右方向の位置決め状態を安定して保持できる。 The position of the positioning pin 33 may be any position as long as it is above the guide groove 18 of the feeder mounting table 14. In this embodiment, the portion of the feeder 13 that is mounted on the feeder mounting table 14. The positioning pin 33 is arranged behind the center in the front-rear direction. This is because the clamp member 21 pushes the feeder 13 forward (the rear wall 14a of the feeder mounting table 14) and the front end of the feeder 13 is positioned by the guide pins 41 and 42, so that the front end of the feeder 13 is a fulcrum. Thus, the characteristic that the rear end portion side of the feeder 13 is easily displaced in the left-right direction within the range of play between the side surface of the guide rail 19 and the edge portion of the guide groove 18 is considered. Therefore, if the positioning pin 33 is disposed on the rear side of the center of the feeder 13 on the feeder mounting table 14 in the front-rear direction, the front end portion side and the rear positioning pin 33 of the feeder 13 The positioning state of the feeder in the front-rear direction and the left-right direction can be stably maintained.
　次に、フィーダ載置台１４へのフィーダ１３の着脱方法を説明する。
　フィーダ１３をフィーダ載置台１４に取り付ける場合は、まず、操作レバー２７をアンクランプ位置（図１の二点鎖線の位置）に操作する。これにより、図３に示すように、クランプ部材２１が上方のアンクランプ位置に移動してフィーダ１３内に引っ込んだ状態になると共に、該クランプ部材２１の係合片３７によって位置決めピン３３がスプリングプランジャ３４の付勢力に抗して退避位置まで押し上げられた状態となる。これにより、クランプ部材２１と位置決めピン３３がフィーダ１３の着脱に邪魔にならない位置に退避した状態となる。 Next, a method for attaching / detaching the feeder 13 to / from the feeder mounting table 14 will be described.
When attaching the feeder 13 to the feeder mounting table 14, first, the operation lever 27 is operated to the unclamping position (the position of the two-dot chain line in FIG. 1). As a result, as shown in FIG. 3, the clamp member 21 is moved to the upper unclamping position and retracted into the feeder 13, and the positioning pin 33 is moved by the engagement piece 37 of the clamp member 21 to the spring plunger. The state is pushed up to the retracted position against the urging force of 34. Thus, the clamp member 21 and the positioning pin 33 are retracted to a position that does not interfere with the attachment / detachment of the feeder 13.
　この状態で、フィーダ１３の下面側のガイドレール１９をフィーダ載置台１４のガイド溝１８に手前側から差し込み、該フィーダ１３の前端部のガイドピン４１，４２をフィーダ載置台１４の奥壁１４ａの位置決め孔４３，４４に挿入して、フィーダ１３の前端部を位置決めしながら該フィーダ１３のコネクタ１６をフィーダ載置台１４の奥壁１４ａのコネクタ１７に差し込み接続する。 In this state, the guide rail 19 on the lower surface side of the feeder 13 is inserted into the guide groove 18 of the feeder mounting table 14 from the front side, and the guide pins 41 and 42 at the front end of the feeder 13 are inserted into the rear wall 14a of the feeder mounting table 14. The connector 16 of the feeder 13 is inserted and connected to the connector 17 of the back wall 14a of the feeder mounting base 14 while being inserted into the positioning holes 43 and 44 and positioning the front end portion of the feeder 13.
　この作業により、フィーダ１３の前端部がフィーダ載置台１４の奥壁１４ａに突き当たった時点で、操作レバー２７をクランプ位置（図１の実線の位置）に操作する。これにより、図２に示すように、クランプ部材２１がフィーダ載置台１４のクランプ穴２２に嵌まり込んでフィーダ１３を前方（フィーダ載置台１４の奥壁１４ａ側）へ押し付けてクランプした状態となり、その過程で、レバー２３が安全スイッチ３１のアクチュエータ３２を押し込んで該安全スイッチ３１がオン状態に切り換えられると共に、クランプ部材２１がクランプ位置に下降する際に、それまで位置決めピン３３の係合フランジ３６を押し上げていたクランプ部材２１の係合片３７も下降するため、スプリングプランジャ３４の付勢力によって位置決めピン３３が下方の突出位置まで押し下げられてガイド溝１８に嵌まり込んだ状態になる（図４参照）。これにより、フィーダ載置台１４上でフィーダ１３が前後方向及び左右方向に位置決めされた状態に取り付けられる。 By this operation, when the front end portion of the feeder 13 hits the back wall 14a of the feeder mounting table 14, the operation lever 27 is operated to the clamp position (the position indicated by the solid line in FIG. 1). As a result, as shown in FIG. 2, the clamp member 21 is fitted into the clamp hole 22 of the feeder mounting table 14, and the feeder 13 is pressed forward (back wall 14 a side of the feeder mounting table 14) and clamped. In the process, the lever 23 pushes the actuator 32 of the safety switch 31 so that the safety switch 31 is turned on, and when the clamp member 21 is lowered to the clamp position, the engaging flange 36 of the positioning pin 33 until then. Since the engaging piece 37 of the clamp member 21 that has pushed up also descends, the positioning pin 33 is pushed down to the downward projecting position by the urging force of the spring plunger 34 and fits into the guide groove 18 (FIG. 4). reference). Thereby, the feeder 13 is attached in the state positioned on the feeder mounting base 14 in the front-rear direction and the left-right direction.
　一方、フィーダ載置台１４上に取り付けたフィーダ１３を取り外す場合は、まず、操作レバー２７をアンクランプ位置（図１の二点鎖線の位置）に操作する。これにより、図３に示すように、クランプ部材２１がクランプ穴２２から斜め上方に引き上げられてクランプ状態（フィーダ１３の前方への押し付け状態）を解除したアンクランプ状態となり、そ
の過程で、レバー２３が安全スイッチ３１のアクチュエータ３２から離れて該安全スイッチ３１がオフ状態に切り換えられると共に、クランプ部材２１の係合片３７によって位置決めピン３３がスプリングプランジャ３４の付勢力に抗して退避位置まで押し上げられた状態となる。これにより、クランプ部材２１と位置決めピン３３がフィーダ１３の着脱に邪魔にならない位置に退避した状態となる。この状態で、フィーダ１３を手前側に引き出せば、フィーダ１３の下面側のガイドレール１９がフィーダ載置台１４のガイド溝１８から抜き出されて、フィーダ１３がフィーダ載置台１４から取り外される。 On the other hand, when removing the feeder 13 attached on the feeder mounting base 14, first, the operation lever 27 is operated to the unclamping position (the position of the two-dot chain line in FIG. 1). As a result, as shown in FIG. 3, the clamp member 21 is lifted obliquely upward from the clamp hole 22 to be in an unclamped state in which the clamped state (the state of pressing the feeder 13 forward) is released. Is separated from the actuator 32 of the safety switch 31 and the safety switch 31 is turned off, and the positioning pin 33 is pushed up to the retracted position against the urging force of the spring plunger 34 by the engagement piece 37 of the clamp member 21. It becomes the state. Thus, the clamp member 21 and the positioning pin 33 are retracted to a position that does not interfere with the attachment / detachment of the feeder 13. When the feeder 13 is pulled out in this state, the guide rail 19 on the lower surface side of the feeder 13 is extracted from the guide groove 18 of the feeder mounting table 14, and the feeder 13 is removed from the feeder mounting table 14.
　以上説明した本実施例では、フィーダ載置台１４にフィーダ１３を取り付けるときに、クランプ部材２１によってフィーダ１３を前方へ押し付けてクランプすると共に、位置決めピン３３を下方に突出させてフィーダ載置台１４のガイド溝１８に嵌め込むことで、フィーダ１３を前後方向及び左右方向に位置決めした状態に取り付けることができる。これにより、フィーダ１３の左右方向の位置精度（部品吸着位置の左右方向の位置精度）を向上できて、吸着ノズル１１の部品吸着動作の安定性を向上できる。しかも、フィーダ１３の着脱時には、位置決めピン３３をフィーダ載置台１４のガイド溝１８から上方に押し上げて退避位置に退避させることで、位置決めピン３３がフィーダ１３の着脱時のスライド移動の邪魔にならず、フィーダ１３をスムーズにスライド移動させることができて、フィーダ１３の着脱作業性を損なうことがない。 In the present embodiment described above, when the feeder 13 is attached to the feeder mounting table 14, the clamp 13 pushes the feeder 13 forward and clamps, and the positioning pin 33 protrudes downward to guide the feeder mounting table 14. By fitting in the groove 18, the feeder 13 can be attached in a state of being positioned in the front-rear direction and the left-right direction. Thereby, the position accuracy of the feeder 13 in the left-right direction (position accuracy in the left-right direction of the component suction position) can be improved, and the stability of the component suction operation of the suction nozzle 11 can be improved. Moreover, when the feeder 13 is attached / detached, the positioning pin 33 is pushed up from the guide groove 18 of the feeder mounting table 14 and retracted to the retracted position, so that the positioning pin 33 does not interfere with the sliding movement when the feeder 13 is attached / detached. The feeder 13 can be smoothly slid and the detachability of the feeder 13 is not impaired.
　しかも、本実施例では、クランプ部材２１の移動を操作する操作レバー２７を、位置決めピン３３の移動を操作する操作手段としても兼用し、クランプ部材２１がクランプ位置に移動する動作に連動して位置決めピン３３が突出位置に移動し、クランプ部材２１がアンクランプ位置に移動する動作に連動して位置決めピン３３が退避位置に移動するように構成したので、フィーダ１３の着脱時に、作業者が１つの操作レバー２７を操作するだけで、クランプ部材２１と位置決めピン３３の両方を適正な位置に移動させることができて、作業者がクランプ部材２１と位置決めピン３３を別々に操作する手間を省くことができ、フィーダ１３の着脱作業性を更に向上できると共に、位置決めピン３３の誤操作を防止できる。 Moreover, in this embodiment, the operation lever 27 for operating the movement of the clamp member 21 is also used as an operation means for operating the movement of the positioning pin 33, and positioning is performed in conjunction with the movement of the clamp member 21 to the clamp position. The pin 33 moves to the protruding position, and the positioning pin 33 moves to the retracted position in conjunction with the movement of the clamp member 21 to the unclamping position. By only operating the operation lever 27, both the clamp member 21 and the positioning pin 33 can be moved to appropriate positions, and the labor of the operator separately operating the clamp member 21 and the positioning pin 33 can be saved. In addition, it is possible to further improve the attaching / detaching workability of the feeder 13 and to prevent erroneous operation of the positioning pin 33.
　但し、本発明は、位置決めピン３３の移動を操作する操作手段と、クランプ部材２１の移動を操作する手段とを別々に設けても良く、この場合でも、本発明の所期の目的は十分に達成できる。 However, in the present invention, the operating means for operating the movement of the positioning pin 33 and the means for operating the movement of the clamp member 21 may be provided separately. Even in this case, the intended purpose of the present invention is sufficient. Can be achieved.
　また、本実施例では、フィーダ載置台１４のガイド溝１８の一部を、位置決めピン３３を嵌まり込ませる嵌合部として使用するようにしたので、フィーダ載置台１４に位置決めピン３３用の嵌合部を新たに形成する必要がなく、従来と同様のフィーダ載置台１４に対しても、そのまま本発明を実施できる利点がある。 Further, in this embodiment, a part of the guide groove 18 of the feeder mounting table 14 is used as a fitting portion into which the positioning pin 33 is fitted, so that the positioning of the positioning pin 33 on the feeder mounting table 14 is performed. There is no need to newly form a joint portion, and there is an advantage that the present invention can be implemented as it is on the feeder mounting table 14 similar to the conventional one.
　但し、本発明は、フィーダ載置台１４に位置決めピン３３を嵌まり込ませる嵌合部をガイド溝１８とは別に形成しても良く、この場合でも、本発明の所期の目的は十分に達成できる。 However, in the present invention, a fitting portion for fitting the positioning pin 33 into the feeder mounting table 14 may be formed separately from the guide groove 18, and even in this case, the intended purpose of the present invention is sufficiently achieved. it can.
　その他、本発明は、本実施例の構成に限定されるものではなく、例えば、クランプ部材２１の移動と位置決めピン３３の移動とを連動させる構成を変更したり、位置決めピン３３を上下動させる構成を変更しても良い等、要旨を逸脱しない範囲内で種々変更して実施できる。 In addition, the present invention is not limited to the configuration of the present embodiment. For example, the configuration in which the movement of the clamp member 21 and the movement of the positioning pin 33 are interlocked, or the positioning pin 33 is moved up and down. It is possible to implement various modifications without departing from the spirit of the invention.
