　取付ベース６の下端部には、ビーズの送り出しを行うビーズ送り機構８が設けてある。取付ベース６の下端部にはＬ字状の第１ブラケット９が固定してあり、第１ブラケット９には第２ブラケット１０が図２において左右方向に位置調整可能に固定してある。第２ブラケット１０には支持プレート１１が前後（図１において左右）の位置調整可能に固定してある。第２ブラケット１０の直角に曲成された支持部１０ａには調整ネジ１２が、その軸心方向への移動不能に枢支してあり、調整ネジ１２のネジ部は支持プレート１１の案内部１１ａのネジ孔に螺合してある。これにより、支持プレート１１の固定を解除し、調整ネジ１２を右回し又は左回しすると、支持プレート１１が第２ブラケット１０に対して前又は後に直線的に動かされて、その前後位置が調整されることとなる。また、第１ブラケット９に対する第２ブラケット１０の固定位置を調整することで、支持プレート１１の左右位置が調整されることとなる。 At the lower end of the mounting base 6, a bead feeding mechanism 8 for feeding beads is provided. An L-shaped first bracket 9 is fixed to the lower end portion of the mounting base 6, and a second bracket 10 is fixed to the first bracket 9 so that the position can be adjusted in the left-right direction in FIG. 2. A support plate 11 is fixed to the second bracket 10 so that the position of the support plate 11 can be adjusted forward and backward (left and right in FIG. 1). An adjustment screw 12 is pivotally supported on the support portion 10a bent at a right angle of the second bracket 10 so as not to move in the axial direction. The screw portion of the adjustment screw 12 is a guide portion 11a of the support plate 11. Are screwed into the screw holes. Accordingly, when the fixing of the support plate 11 is released and the adjustment screw 12 is rotated clockwise or counterclockwise, the support plate 11 is linearly moved forward or backward with respect to the second bracket 10 and the front-rear position thereof is adjusted. The Rukoto. Further, by adjusting the fixing position of the second bracket 10 with respect to the first bracket 9, the left and right positions of the support plate 11 are adjusted.
　支持プレート１１の下面には駆動モータ１３が固定してあり、駆動モータ１３のモータ軸には駆動ギヤ１４が固定してある。駆動モータ１３の下面にはＬ字状のベースブラケット１５が固定してあり、ベースブラケット１５にはベース部材１６が固定してある。 The drive motor 13 is fixed to the lower surface of the support plate 11, and the drive gear 14 is fixed to the motor shaft of the drive motor 13. An L-shaped base bracket 15 is fixed to the lower surface of the drive motor 13, and a base member 16 is fixed to the base bracket 15.
　図３にはベース部材１６の部分の平面略図が示してあり、図４にはベース部材１６の部分の立体分解図が示してある。これらの図より明らかなように、駆動モータ１３の駆動ギヤ１４には従動ギヤ１７が噛合してある。従動ギヤ１７の下端には作動アーム１８が一体的に設けてある。従動ギヤ１７及び作動アーム１８は、カラー２０上に置かれ、段付ネジ１９を介して該カラー２０により回転自在に支持される。すなわち、段付ネジ１９の先端のネジ部分がカラー２０に螺合し、従動ギヤ１７及び作動アーム１８の中心孔を通る段付ネジ１９の円筒部分にはネジ溝がないことにより、従動ギヤ１７及び作動アーム１８はカラー２０に対して回転自在となっている。 3 shows a schematic plan view of the base member 16 portion, and FIG. 4 shows a three-dimensional exploded view of the base member 16 portion. As is apparent from these drawings, the driven gear 17 is engaged with the drive gear 14 of the drive motor 13. An operating arm 18 is integrally provided at the lower end of the driven gear 17. The driven gear 17 and the operating arm 18 are placed on a collar 20 and are rotatably supported by the collar 20 via a stepped screw 19. That is, the screw portion at the tip of the stepped screw 19 is screwed into the collar 20, and the cylindrical portion of the stepped screw 19 passing through the center hole of the driven gear 17 and the operating arm 18 has no thread groove. The operating arm 18 is rotatable with respect to the collar 20.
　カラー２０の外形は、略中間より下方が縮径されており、トーションバネ２１のコイル軸２１ａが嵌装されるようになっている。カラー２０は、トーションバネ２１のコイル軸２１ａを嵌装した状態で取付ネジ２２によりベース部材１６に固定してある。これにより、駆動モータ１３を駆動して駆動ギヤ１４を回転させると、従動ギヤ１７を介して作動アーム１８が回動することとなる。 The outer shape of the collar 20 is reduced in diameter from substantially the middle, and the coil shaft 21a of the torsion spring 21 is fitted therein. The collar 20 is fixed to the base member 16 with a mounting screw 22 in a state where the coil shaft 21 a of the torsion spring 21 is fitted. As a result, when the drive motor 13 is driven to rotate the drive gear 14, the operating arm 18 is rotated via the driven gear 17.
　ベース部材１６には、Ｖ字状の第１ガイド板２３が固定してあるとともに、第１ガイド板２３の両外側に対して一定の間隔を空けて１対の第２ガイド板２４、２４が配置され、固定してある。第１ガイド板２３と両第２ガイド板２４、２４の間にはそれぞれ送り部材２５、２５が設けてあり、該送り部材２５、２５は第１ガイド板２３と第２ガイド板２４との間で、Ｖ字の成す斜め方向に沿って摺動することが可能となっている。該送り部材２５の後端部上面には、作動アーム１８と当接可能な作動ピン２６が固定してある。作動ピン２６にはトーションバネ２１の両端の掛け部２１ｂ、２１ｂが引掛けてあり、送り部材２５には後方に移動する付勢が働いている。これにより、駆動モータ１３を駆動して作動アーム１８を図３において時計方向に回動すると、作動アーム１８が左側の送り部材２５の作動ピン２６と当接して左側の送り部材２５を前進させることとなる。一方、作動アーム１８を図３において反時計方向に回動すると、作動アーム１８が右側の送り部材２５の作動ピン２６と当接して右側の送り部材２５を前進させることとなる。なお、送り部材２５の前進方向とは、第１ガイド板２３の成すＶ字の角の方向であり、換言すれば、トーションバネ２１の付勢力に抗して動く方向である。駆動モータ１３から送り部材２５に到る駆動機構が、複数の送り部材の１つを選択的に駆動する駆動機構に相当する。 A V-shaped first guide plate 23 is fixed to the base member 16, and a pair of second guide plates 24, 24 are spaced apart from both outer sides of the first guide plate 23. Arranged and fixed. Feed members 25, 25 are provided between the first guide plate 23 and the second guide plates 24, 24, respectively. The feed members 25, 25 are located between the first guide plate 23 and the second guide plate 24. Thus, it is possible to slide along the oblique direction formed by the V-shape. An operation pin 26 that can contact the operation arm 18 is fixed to the upper surface of the rear end portion of the feed member 25. The operating pin 26 is hooked with hooks 21b and 21b at both ends of the torsion spring 21, and the feed member 25 is urged to move backward. Thus, when the drive motor 13 is driven and the operating arm 18 is rotated clockwise in FIG. 3, the operating arm 18 contacts the operating pin 26 of the left feeding member 25 to advance the left feeding member 25 forward. It becomes. On the other hand, when the operating arm 18 is rotated counterclockwise in FIG. 3, the operating arm 18 comes into contact with the operating pin 26 of the right feeding member 25 to advance the right feeding member 25. The forward direction of the feed member 25 is the direction of the V-shaped corner formed by the first guide plate 23, in other words, the direction in which the feed member 25 moves against the urging force of the torsion spring 21. A drive mechanism from the drive motor 13 to the feed member 25 corresponds to a drive mechanism that selectively drives one of the plurality of feed members.
　第１ガイド板２３と第２ガイド板２４、２４の厚みは送り部材２５の厚みより僅かに厚く設定してあり、第１ガイド板２３、第２ガイド板２４、２４の先方部上面には第２ガイド板２４、２４に跨ってパイプ土台２７が固定してある。このパイプ土台２７によって、送り部材２５の上下のバタツキが抑制されている。パイプ土台２７にはビーズＢを通す２つの貫通孔２７ａ、２７ａが形成してあり、各貫通孔２７ａ、２７ａには単体のビーズＢを積層して収納する２つの収納管２８、２８の下端に固定された連結部材２９、２９がそれぞれ嵌合してある。図1及び図２に示すように、各収納管２８、２８の中間部は、取付ベース６に固定した第１ブラケット３０、及び、第１ブラケット３０に固定した第２ブラケット３１に固定してある。この収納管２８の中間部の固定は、対向する２部材にて収納管２８を挟み込んで固定しており、ネジ３２を緩めることで収納管２８を簡易に取り外すことができるようになっている。 The thicknesses of the first guide plate 23 and the second guide plates 24 and 24 are set to be slightly thicker than the thickness of the feed member 25, and the first guide plate 23 and the second guide plates 24 and 24 are not 2 A pipe base 27 is fixed across the guide plates 24, 24. By this pipe base 27, the upper and lower fluttering of the feed member 25 is suppressed. The pipe base 27 is formed with two through- holes 27a and 27a through which the beads B are passed. The through- holes 27a and 27a are formed at the lower ends of the two storage pipes 28 and 28 for storing the single beads B in a stacked manner. Fixed connecting members 29 and 29 are respectively fitted. As shown in FIGS. 1 and 2, the intermediate portion of each storage tube 28 is fixed to a first bracket 30 fixed to the mounting base 6 and a second bracket 31 fixed to the first bracket 30. . The intermediate portion of the storage tube 28 is fixed by sandwiching the storage tube 28 between two opposing members, and the storage tube 28 can be easily removed by loosening the screw 32.
　各送り部材２５の先端部には、ビーズＢを真直ぐ送り出せるように、送り出すビーズＢの一部が入り込む凹部２５ａが形成してある。送り部材２５は、略中間より先方部分の底面が高く形成してあり、その先方部分の下方のスペースには支持部材３３が配置してある。支持部材３３の前方の沈め部３３ａには一対の保持爪３４、３４が対向して設けてあるとともに、支持部材３３の先端部には縫針４の貫通を許容する凹部３３ｂが形成してある。この支持部材３３の凹部３３ｂ上にて収納管２８より導かれたビーズＢを支承するようになっている。一対の保持爪３４、３４は、その先方の爪部にてビーズＢを保持できるように、爪部はビーズＢの外周に倣った円弧状に形成してある。保持爪３４、３４には、それぞれ係合孔３４ａが形成してあるとともに、その外側に係合溝３４ｂが形成してある。保持爪３４の係合孔３４ａには、支持部材３３に立設した第１ピン３５が挿入してあり、保持爪３４は係合孔３４ａを中心とした回動が可能に支持部材３３に支持してある。また、保持爪３４の係合溝３４ｂには、送り部材２５の先方部に立設した第２ピン３６が係合してある。これにより、送り部材２５と支持部材３３とが相対的に移動すると、両保持爪３４、３４が回動されることとなり、両保持爪３４、３４の回動が規制されると送り部材２５とともに支持部材３３が移動することとなる。支持部材３３には、底面から突出する係合ピン３７が設けてあり、ベース部材１６には係合ピン３７が係合する長溝１６ａがそれぞれ形成してある。そして、送り部材２５は、常にはトーションバネ２１の付勢によって支持部材３３の係合ピン３７が長溝１６ａの後端に当接する位置に保持される。 A recess 25a into which a part of the bead B to be fed enters is formed at the tip of each feed member 25 so that the bead B can be fed straight. The feed member 25 is formed such that the bottom surface of the front portion is higher than the middle, and the support member 33 is disposed in the space below the front portion. A pair of holding claws 34, 34 are provided facing the sinking portion 33 a in front of the support member 33, and a recess 33 b that allows the sewing needle 4 to pass therethrough is formed at the distal end portion of the support member 33. The bead B guided from the storage tube 28 is supported on the recess 33b of the support member 33. The pair of holding claws 34, 34 are formed in an arc shape that follows the outer periphery of the bead B so that the bead B can be held by the tip of the claw. Each of the holding claws 34 and 34 has an engagement hole 34a and an engagement groove 34b on the outside thereof. A first pin 35 erected on the support member 33 is inserted into the engagement hole 34a of the holding claw 34, and the holding claw 34 is supported by the support member 33 so as to be able to rotate around the engagement hole 34a. It is. Further, a second pin 36 erected on the front portion of the feed member 25 is engaged with the engagement groove 34 b of the holding claw 34. As a result, when the feed member 25 and the support member 33 move relative to each other, both the holding claws 34 and 34 are rotated. When the rotation of the both holding claws 34 and 34 is restricted, together with the feed member 25 The support member 33 will move. The support member 33 is provided with an engagement pin 37 protruding from the bottom surface, and the base member 16 is formed with a long groove 16a with which the engagement pin 37 is engaged. The feed member 25 is always held at a position where the engagement pin 37 of the support member 33 comes into contact with the rear end of the long groove 16a by the urging of the torsion spring 21.
　次に、本実施例によるビーズＢの縫着について説明する。
　最初に、各収納管２８、２８内に、各収納管２８毎に互いに異なるタイプのビーズＢをそれぞれ積層した状態でセットする。なお、収納管２８に積層収納した最上段のビーズＢの上には、図１に示すように積層したビーズＢが供給されるのに伴ってスムーズに落ちるように３つの錘３８、３９、４０が嵌装してあり、最下端の錘４０の下方部にはバネ４１が設けてある。なお、異なるタイプのビーズＢとは、例えば、色、形状、サイズの少なくともいずれか１つが異なるものであればよい。なお、各収納管２８、２８の内径は、そこに収納するビーズＢのサイズ（直径）に合わせたサイズとする。これに伴い、ビーズＢに接する後述する各構成要素の寸法も、適用されるビーズＢのサイズ（直径）に合わせた寸法とするものとする。なお、図示例では、便宜上、２つの収納管２８、２８に収納される各タイプのビーズＢのサイズが同じ場合について図示している。 Next, the sewing of the beads B according to the present embodiment will be described.
First, in each storage tube 28, 28, different types of beads B are set in a stacked state for each storage tube 28. It should be noted that three weights 38, 39, and 40 are placed on the uppermost beads B stacked and stored in the storage tube 28 so as to smoothly fall as the stacked beads B are supplied as shown in FIG. And a spring 41 is provided below the lowermost weight 40. Note that different types of beads B may be different in at least one of color, shape, and size, for example. The inner diameter of each storage tube 28, 28 is set to a size that matches the size (diameter) of the beads B stored therein. In connection with this, the dimension of each component mentioned later which touches bead B shall also be a size according to the size (diameter) of bead B applied. In the illustrated example, the case where the size of each type of bead B stored in the two storage tubes 28, 28 is the same is illustrated for convenience.
　各収納管２８、２８に各タイプのビーズＢをセットしたら、ミシンを起動してビーズ送り機構８の駆動モータ１３を駆動して、刺繍データの指示に従い縫いに使用すべきビーズＢに対応する、一方の送り部材２５を前進及び後退駆動させて、それに対応する一方の収納管２８にセットされたビーズＢを送り出すとともに、ミシンヘッドＭの縫い動作によって送り出されたビーズＢを被縫製体に縫着する。 When each type of bead B is set in each storage tube 28, 28, the sewing machine is started and the drive motor 13 of the bead feed mechanism 8 is driven to correspond to the bead B to be used for sewing in accordance with the instruction of the embroidery data. One feed member 25 is driven forward and backward to feed the corresponding beads B set in one of the storage pipes 28, and the beads B fed by the sewing operation of the sewing head M are sewn to the workpiece. To do.
　最初、各送り部材２５、２５は図３に示す最も後退した位置（中立位置）にある。このとき、各収納管２８、２８にセットされたビーズＢの最下端のビーズＢがパイプ土台２７の貫通孔２７ａを通って支持部材３３上に至って、一対の保持爪３４、３４間で送り部材２５の先端部凹部２５ａの前に位置する。このとき、一対の保持爪３４、３４は少し開いた状態となっている。 First, each feed member 25, 25 is in the most retracted position (neutral position) shown in FIG. At this time, the lowermost bead B of the bead B set in each storage tube 28, 28 reaches the support member 33 through the through hole 27 a of the pipe base 27, and feeds between the pair of holding claws 34, 34. It is located in front of the 25 front end recesses 25a. At this time, the pair of holding claws 34, 34 are in a slightly opened state.
　この状態から駆動モータ１３を正転又は逆転駆動して作動アーム１８を時計方向又は反時計方向に回動させる。例えば作動アーム１８を図３において時計方向に回動させると左側の送り部材２５が前進する。一方、作動アーム１８を図３において反時計方向に回動させると右側の送り部材２５が前進する。このように作動アーム１８を時計方向または反時計方向に回動させることによって左右どちらかの送り部材２５が前進され、これにより、どちらの収納管２８、２８からビーズＢを送り出すかが選択される（すなわち、縫いに使用するビーズＢが選択される）。 In this state, the drive motor 13 is driven forward or backward to rotate the operating arm 18 clockwise or counterclockwise. For example, when the operating arm 18 is rotated clockwise in FIG. 3, the left feeding member 25 moves forward. On the other hand, when the operating arm 18 is rotated counterclockwise in FIG. 3, the right feeding member 25 moves forward. Thus, by rotating the operating arm 18 clockwise or counterclockwise, the left or right feeding member 25 is advanced, and thereby it is selected from which storage tube 28, 28 the beads B are sent out. (That is, the bead B used for sewing is selected).
　この選択された一方の送り部材２５が前進すると、前進当初は送り部材２５のみが移動して、一対の保持爪３４、３４が内側に回動して支持部材３３上のビーズＢを挟み込んで保持する。その後は、ビーズＢを保持することによって両保持爪３４、３４の回動が規制され、送り部材２５とともに支持部材３３が移動して送り部材２５が最も前進した状態へと至る。このとき、支持部材３３の係合ピン３７はベース部材１６の長溝１６ａの前端に当接し、送り部材２５の前進限界位置が規制される。図５には右側の送り部材２５が最も前進した状態が示してある。この送り部材２５が最も前進した状態（前進限界位置）では、送り出されたビーズＢの縫止孔が縫針４の針落ち上に合致する（すなわち、所定の針真下位置に位置決めされる）。これにより、縫い動作時に下降する縫針４は、該所定の針真下位置まで送り出されたビーズＢの縫止孔内に確実に嵌入し得る。なお、ビーズＢが収納管２８内に収納されるとき、収納管２８内で積層された各ビーズＢの縫止孔が垂直方向（縫針４の上下動方向）を指向するように、きちんと整列される。 When the selected one feed member 25 moves forward, only the feed member 25 moves at the beginning of the advance, and the pair of holding claws 34 and 34 rotate inward to hold and hold the beads B on the support member 33. To do. Thereafter, holding the beads B restricts the rotation of the holding claws 34, 34, and the support member 33 moves together with the feed member 25, and the feed member 25 reaches the most advanced state. At this time, the engagement pin 37 of the support member 33 contacts the front end of the long groove 16a of the base member 16, and the advance limit position of the feed member 25 is regulated. FIG. 5 shows a state in which the right feeding member 25 is most advanced. In the state in which the feeding member 25 is most advanced (advance limit position), the stitching hole of the bead B that is fed out coincides with the needle drop of the sewing needle 4 (that is, positioned at a predetermined position just below the needle). As a result, the sewing needle 4 that descends during the sewing operation can be surely fitted into the sewing hole of the bead B fed to the position just below the predetermined needle. When the beads B are stored in the storage tube 28, the beads B stacked in the storage tube 28 are properly aligned so that the sewing holes of the beads B are oriented in the vertical direction (the vertical movement direction of the sewing needle 4). The
　縫針４がビーズＢの縫止孔に嵌入後、駆動モータ１３を前進時とは逆方向に回転して作動アーム１８を元の位置まで回動させる。作動アーム１８が元の位置の方へと回動し始めると、送り部材２５はトーションバネ２１の付勢によって後退を始める。後退当初は送り部材２５のみが移動して、一対の保持爪３４、３４が外側に回動してビーズＢの保持を開放する。両保持爪３４、３４の外側への回動は互いの後方部が当接することで停止し、その後は送り部材２５とともに支持部材３３が後退を始める。 After the sewing needle 4 is inserted into the sewing hole of the bead B, the drive motor 13 is rotated in the opposite direction to that in the forward movement to rotate the operating arm 18 to the original position. When the operating arm 18 starts to rotate toward the original position, the feed member 25 starts to retract due to the urging of the torsion spring 21. At the beginning of retreat, only the feeding member 25 moves, and the pair of holding claws 34 and 34 rotate outward to release the holding of the beads B. The rotation of the holding claws 34, 34 to the outside stops when the rear portions of the holding claws 34 come into contact with each other, and thereafter, the support member 33 starts moving backward together with the feed member 25.
　送り部材２５が支持部材３３とともに更に後退して、ビーズＢを支承していた支持部材３３がビーズＢの後方まで後退すると、ビーズＢが縫針４に沿って被縫製物上に落下し、以降の縫い動作によってビーズＢが被縫製物に縫い付けられる。そして、送り部材２５は図３に示す中立位置まで後退し、次のビーズＢが支持部材３３上に位置する。 When the feed member 25 is further retracted together with the support member 33 and the support member 33 supporting the beads B is retracted to the rear of the beads B, the beads B fall on the sewing object along the sewing needles 4 and thereafter. The beads B are sewn on the workpiece by the sewing operation. Then, the feed member 25 is retracted to the neutral position shown in FIG. 3, and the next bead B is positioned on the support member 33.
　以降、前進及び後退駆動させる送り部材２５を任意に切替えながら、上記動作を繰り返すことによって縫い付けるビーズＢのタイプを切り替えながらビーズＢの縫着が次々と行われることとなる。従って、異なる２タイプのビーズＢを任意に組み合わせた縫い模様を容易に形成することができる。 Thereafter, the beads B are sewn one after another while switching the type of the beads B to be sewn by repeating the above operation while arbitrarily switching the feed member 25 to be driven forward and backward. Therefore, a sewing pattern in which two different types of beads B are arbitrarily combined can be easily formed.
　本実施例において、駆動モータ１３の駆動を駆動ギヤ１４、従動ギヤ１７を介して作動アーム１８に伝達する構成としたが、ギヤの替わりにタイミングプーリやタイミングベルトを使用する構成としても良いし、あるいはリンクなど他の伝達機構としてもよい。 In the present embodiment, the drive of the drive motor 13 is transmitted to the operation arm 18 via the drive gear 14 and the driven gear 17, but a configuration using a timing pulley or a timing belt instead of the gear may be used. Alternatively, another transmission mechanism such as a link may be used.
　なお、駆動モータ１３の駆動を駆動ギヤ１４、従動ギヤ１７を介して作動アーム１８に伝達する構成としたのは、駆動モータ１３と収納管２８、２８との干渉を避けるためであり、配置上問題がなければ駆動モータ１３のモータ軸に作動アーム１８を直接設けるようにしてもよいのは勿論である。 The reason why the drive of the drive motor 13 is transmitted to the operating arm 18 via the drive gear 14 and the driven gear 17 is to avoid interference between the drive motor 13 and the storage tubes 28, 28. Of course, if there is no problem, the operating arm 18 may be provided directly on the motor shaft of the drive motor 13.
　なお、この第１実施例において、３以上のタイプのビーズＢを選択可能にするには、追加の収納管２８を設け、かつ、これに対応する追加の送り部材２５を針落ち位置に選択的にガイドするための機構を放射状に増設すればよい。 In the first embodiment, in order to select three or more types of beads B, an additional storage tube 28 is provided, and an additional feed member 25 corresponding thereto is selectively provided at the needle drop position. It is only necessary to add a mechanism for guiding to the radial direction.
　次に、本発明の第２実施例に係るビーズ送り装置４２について説明する。
　図６は第２実施例に係るビーズ送り装置４２の右側面図、図７は該ビーズ送り装置４２の正面図である。このビーズ送り装置４２も上記第１実施例と同様に第１ブラケット９、第２部ブラケット１０を介して取付ベース６の下端部に設けるようになっている。 Next, a bead feeder 42 according to a second embodiment of the present invention will be described.

The bead feeding device 42 is also provided at the lower end of the mounting base 6 via the first bracket 9 and the second bracket 10 in the same manner as in the first embodiment.
　第２ブラケット１０には支持プレート４３が、第１実施例と同様に前後（図６において左右）の位置調整可能に固定してある。支持プレート４３の下端にはベース部材４４が固定してある。支持プレート４３には駆動モータ４５が固定してあり、そのモータ軸には揺動アーム４６が固定してある。 The support plate 43 is fixed to the second bracket 10 so that the front and rear positions (left and right in FIG. 6) can be adjusted in the same manner as in the first embodiment. A base member 44 is fixed to the lower end of the support plate 43. A drive motor 45 is fixed to the support plate 43, and a swing arm 46 is fixed to the motor shaft.
　図８にはベース部材４４の部分の平面略図が示してあり、図９にはベース部材４４の部分の立体分解図が示してある。これらの図より明らかなように、揺動アーム４６の先端には連結ピン４７が固定してあり、連結ピン４７はＬ字状の連結部材４８に形成された係合凹部４８ａに嵌合してある。連結部材４８は、ベース部材４４上に載置された送り部材４９の上面に固定してある。これにより、駆動モータ４５の駆動によって揺動アーム４６が所定角度範囲で往復揺動駆動されると、送り部材４９が前進及び後退駆動されることとなる。これらの駆動モータ４５、揺動アーム４６、連結部材４８等を含む機構が、送り部材４９を駆動するための駆動機構に相当する。 8 shows a schematic plan view of the base member 44, and FIG. 9 shows a three-dimensional exploded view of the base member 44. As is apparent from these drawings, a connecting pin 47 is fixed to the tip of the swing arm 46, and the connecting pin 47 is fitted into an engaging recess 48a formed in an L-shaped connecting member 48. is there. The connecting member 48 is fixed to the upper surface of the feed member 49 placed on the base member 44. Thus, when the swing arm 46 is reciprocally swung within a predetermined angle range by driving the drive motor 45, the feed member 49 is driven forward and backward. A mechanism including the drive motor 45, the swing arm 46, the connecting member 48, and the like corresponds to a drive mechanism for driving the feed member 49.
　ベース部材４４の上面には、送り部材４９の左右に位置する一対のガイド板５０、５０が固定してあり、この両ガイド板５０、５０によって、送り部材４９の前進及び後退が案内される。一対のガイド板５０、５０の先方部上面には両ガイド板５０、５０に跨ってパイプ土台５１が固定してある。パイプ土台５１にはビーズＢを通す２つの貫通孔５１ａ、５１ａが形成してあり、貫通孔５１ａ、５１ａには各収納管２８、２８の下端に固定された連結部材２９、２９がそれぞれ嵌合してある。この収納管２８を固定するための構成は前記第１実施例と同様である。 A pair of guide plates 50, 50 positioned on the left and right of the feed member 49 are fixed on the upper surface of the base member 44, and the forward and backward movements of the feed member 49 are guided by both guide plates 50, 50. A pipe base 51 is fixed to the upper surfaces of the front ends of the pair of guide plates 50, 50 across the guide plates 50, 50. The pipe base 51 is formed with two through holes 51a and 51a through which the beads B are passed. The through holes 51a and 51a are fitted with connecting members 29 and 29 fixed to the lower ends of the storage tubes 28 and 28, respectively. It is. The structure for fixing the storage tube 28 is the same as that in the first embodiment.
　送り部材４９の先端部には、前記第１実施例と同様に凹部４９ａが形成してある。また、送り部材４９には、第１実施例と同様に支持部材３３、一対の保持爪３４、３４が設けてある。そして、ベース部材４４には、支持部材３３の係合ピン３７が係合する長溝４４ａが形成してある。 A recess 49a is formed at the tip of the feed member 49 as in the first embodiment. Further, the feed member 49 is provided with a support member 33 and a pair of holding claws 34, 34 as in the first embodiment. The base member 44 is formed with a long groove 44 a that engages with the engagement pin 37 of the support member 33.
　ベース部材４４の側面にはモータブラケット５２が固定してあり、モータブラケット５２にはリニアモータ５３が固定してある。リニアモータ５３のスライドロッド５３ａにはブロック５４が固定してあり、ブロック５４には揺動レバー５５の一端が段付ピン５６により連結してある。揺動レバー５５は、略中間部をモータブラケット５２に固定したスペーサ５７に段付ピン５８にて揺動自在に支持してあり、揺動レバー５５の他端にはＵ字状の係合溝５５ａが形成してある。揺動レバー５５の係合溝５５ａには、スライドプレート５９に立設された係合ピン６０が係合してある。スライドプレート５９には、ビーズＢが入り込む１つの案内孔５９ａが形成してあり、該案内孔５９ａ内に１つのビーズＢを受け入れて搬送する。スライドプレート５９は、ベース部材４４に形成した抜き穴４４ｂに通して、一対のガイド板５０、５０の上面に載置してある。パイプ土台５１には、スライドプレート５９を摺動可能に案内する案内溝５１ｂが形成してあり、案内溝５１ｂにスライドプレート５９が嵌合してある。これにより、リニアモータ５３を駆動してスライドロッド５３ａを前進及び後退させると、揺動レバー５５を介してスライドプレート５９が左右にスライドすることとなる。 The motor bracket 52 is fixed to the side surface of the base member 44, and the linear motor 53 is fixed to the motor bracket 52. A block 54 is fixed to the slide rod 53 a of the linear motor 53, and one end of a swing lever 55 is connected to the block 54 by a stepped pin 56. The swing lever 55 is supported by a spacer 57 having a substantially intermediate portion fixed to the motor bracket 52 by a stepped pin 58 so as to be swingable. A U-shaped engagement groove is formed at the other end of the swing lever 55. 55a is formed. An engagement pin 60 erected on the slide plate 59 is engaged with the engagement groove 55 a of the swing lever 55. The slide plate 59 is formed with one guide hole 59a into which the bead B enters, and the single bead B is received and conveyed into the guide hole 59a. The slide plate 59 is placed on the upper surfaces of the pair of guide plates 50, 50 through a punched hole 44 b formed in the base member 44. The pipe base 51 is formed with a guide groove 51b for slidably guiding the slide plate 59, and the slide plate 59 is fitted in the guide groove 51b. As a result, when the linear motor 53 is driven to move the slide rod 53 a forward and backward, the slide plate 59 slides to the left and right via the swing lever 55.
　中立状態において、スライドプレート５９は、図８に示すように、その案内孔５９ａがパイプ土台５１の２つの貫通孔５１ａ、５１ａの中間で、送り部材４９に設けられた一対の保持爪３４、３４の間に合致している。この中立状態におけるスライドプレート５９の案内孔５９ａの位置を「送り出し位置」という。すなわち、案内孔５９ａに入り込んだ状態で搬送されてきたビーズＢが、この「送り出し位置」に位置するとき、送り部材４９の前進に応じて、針直下位置の方に送り出され得るようになる。 In the neutral state, as shown in FIG. 8, the slide plate 59 has a pair of holding claws 34, 34 provided on the feed member 49, with the guide hole 59 a being intermediate between the two through holes 51 a, 51 a of the pipe base 51. It matches between. The position of the guide hole 59a of the slide plate 59 in the neutral state is referred to as “feeding position”. That is, when the bead B that has been conveyed in the state of entering the guide hole 59a is positioned at this “feeding position”, it can be fed toward the position directly below the needle in accordance with the advancement of the feeding member 49.
　この中立状態からリニアモータ５３を一方向に駆動してスライドプレート５９をスライドさせて、その案内孔５９ａをパイプ土台５１の一方の貫通孔５１ａに合致させると、該貫通孔５１ａに対応する一方の収納管２８のビーズＢを選択した状態となる。図１０にはスライドプレート５９を右にスライドして、その案内孔５９ａをパイプ土台５１の右側の貫通孔５１ａに合致させた状態が示してある。これにより、右側の収納管２８にセットされたビーズＢの最下端のビーズＢがスライドプレート５９の案内孔５９ａ内に位置（落下）し、該ビーズＢが選択された状態となる。案内孔５９ａ内に位置した１つのビーズＢは、その下側のガイド板５０によって支持され、その後のスライドプレート５９の移動に伴って搬送される。 When the linear motor 53 is driven in one direction from the neutral state to slide the slide plate 59 so that the guide hole 59a is aligned with the one through hole 51a of the pipe base 51, the one corresponding to the through hole 51a is provided. The bead B of the storage tube 28 is selected. FIG. 10 shows a state in which the slide plate 59 is slid to the right and the guide hole 59a is aligned with the right through hole 51a of the pipe base 51. As a result, the lowermost bead B of the bead B set in the right storage tube 28 is positioned (dropped) in the guide hole 59a of the slide plate 59, and the bead B is selected. One bead B located in the guide hole 59a is supported by the lower guide plate 50, and is conveyed along with the subsequent movement of the slide plate 59.
　次に、リニアモータ５３を前記とは逆方向に駆動して図１１に示すようにスライドプレート５９を元の中立状態（送り出し位置）に戻す。これにより、スライドプレート５９の案内孔５９ａ内に入って搬送されてきたビーズＢが両ガイド板５０の間からその下の支持部材３３上に落下して、一対の保持爪３４、３４間で送り部材４９の先端部凹部４９ａの前に位置する。すなわち、スライドプレート５９を介して選択された１つのビーズＢが所定の送り出し位置に位置される。このように、リニアモータ５３を駆動してスライドプレート５９をスライドさせることによって、どちらか一方の収納管２８にセットされた所望のタイプのビーズＢを選択して所定の送り出し位置すなわち支持部材３３上に位置させることができる。リニアモータ５３及びスライドプレート５９を含む機構が、複数の収納管２８のうちの選択された１つの収納管から１つのビーズＢを所定の送り出し位置まで移動させる選択機構に相当する。 Next, the linear motor 53 is driven in the opposite direction to return the slide plate 59 to the original neutral state (feeding position) as shown in FIG. As a result, the bead B that has been transferred into the guide hole 59a of the slide plate 59 falls between the two guide plates 50 onto the support member 33 thereunder, and is sent between the pair of holding claws 34, 34. The member 49 is positioned in front of the concave portion 49a. That is, one bead B selected through the slide plate 59 is positioned at a predetermined delivery position. In this way, by driving the linear motor 53 and sliding the slide plate 59, a desired type of beads B set in one of the storage tubes 28 is selected and a predetermined delivery position, that is, on the support member 33 is selected. Can be located. A mechanism including the linear motor 53 and the slide plate 59 corresponds to a selection mechanism that moves one bead B from a selected one of the plurality of storage tubes 28 to a predetermined delivery position.
　このようにスライドプレート５９のスライドによって所望のタイプのビーズＢを選択して支持部材３３上（送り出し位置）に位置させたら、駆動モータ４５を駆動して送り部材４９を前進させて、該送り出し位置に位置する選択されたビーズＢを所定の針直下位置まで送り出す。それから、駆動モータ４５を逆転駆動して送り部材４９を後退させる。なお、この送り部材４９を前進及び後退駆動させてのビーズＢの縫い付け動作は、前記第１実施例と略同様であるため詳しい説明は省略する。 Thus, when the desired type of beads B is selected by sliding on the slide plate 59 and positioned on the support member 33 (feeding position), the driving motor 45 is driven to move the feeding member 49 forward, and the feeding position. The selected bead B positioned at is sent out to a position just below a predetermined needle. Then, the drive motor 45 is reversely driven to move the feed member 49 backward. Note that the sewing operation of the beads B by driving the feed member 49 forward and backward is substantially the same as in the first embodiment, and a detailed description thereof will be omitted.
　なお、この第２実施例においては、異なるタイプのビーズＢに対して同じプレート５９の案内孔５９ａが使用されるため、各タイプのビーズＢのサイズは同じである必要があるが、色又は形状は適宜に異ならせることができる。また、この第２実施例において、３以上のタイプのビーズＢを選択可能にするには、２つの収納管２８の配列に横並びになるように収納管２８を増設し、プレート５９のスライド範囲を広げればよい。 In the second embodiment, since the guide holes 59a of the same plate 59 are used for different types of beads B, the size of each type of beads B needs to be the same. Can be varied as appropriate. Further, in this second embodiment, in order to make it possible to select three or more types of beads B, the storage tubes 28 are added so that they are arranged side by side in the arrangement of the two storage tubes 28, and the slide range of the plate 59 is increased. Just spread it.
　以上説明したように、第１及び第２実施例に係る本発明によれば、複数の収納管２８のうちいずれか１つにセットされたビーズＢを選択して送り出すことが可能であり、縫いの途中で縫い付けるビーズを切替えることができることとなる。従って、異なる複数タイプのビーズＢを任意に組み合わせた縫い模様を形成することができる。 As described above, according to the present invention relating to the first and second embodiments, it is possible to select and send out the beads B set in any one of the plurality of storage tubes 28, and to sew The beads to be sewn can be switched in the middle of the process. Therefore, a sewing pattern can be formed by arbitrarily combining different types of beads B.
