Description
本発明は、鍔付き帽子の前面部や側面部に、刺繍ミシンにより複数色の刺繍糸を用いて刺繍を施す帽子枠装置に設けられた姿勢規制機構に関し、特に帽子枠を装着した場合でも、回動フレームの姿勢を容易に正規の姿勢に規制（修正）できるようにしたものに関する。 The present invention relates to a posture regulating mechanism provided in a hat frame device that performs embroidery on a front surface and a side surface of a hat with a collar using an embroidery thread by using an embroidery sewing machine, and even when the hat frame is mounted, The present invention relates to a structure in which the posture of a rotating frame can be easily regulated (corrected) to a normal posture.
被縫製物に種々の刺繍模様を施す刺繍ミシンは、一般的に、被縫製物をＹ方向（前後方向）へ送るためのＹ方向送り枠と、Ｘ方向（左右方向）へ送るＸ方向送り枠とを備え、帽子の前面部に種々の刺繍模様を形成する帽子枠装置が、Ｙ方向送り枠とＸ方向送り枠とに夫々取付けられる。一方、帽子枠装置は、Ｙ方向送り枠に連結される本体フレームと、この本体フレームに回動自在に支持された回動フレームと、この回動フレームに取付けられる帽子枠であって、刺繍縫いを施す鍔付き帽子をセットする帽子枠等を備えている（例えば、特許文献１）。 An embroidery sewing machine that applies various embroidery patterns to a sewing product is generally provided with a Y-direction feed frame for sending the sewing product in the Y direction (front-rear direction) and an X-direction feed frame for sending it in the X direction (left-right direction). And a hat frame device for forming various embroidery patterns on the front surface of the hat is attached to the Y-direction feed frame and the X-direction feed frame, respectively. On the other hand, the hat frame device includes a main body frame connected to the Y-direction feed frame, a rotating frame rotatably supported on the main body frame, and a hat frame attached to the rotating frame, and includes embroidery sewing. A hat frame or the like for setting a hat with a hook for performing the above is provided (for example, Patent Document 1).
即ち、この種の帽子枠装置では、本体フレーム側に設けた複数のローラや規制ブロックを、回動フレームの内周面に形成したローラ溝に内側から係合させるようにして、回動フレームを本体フレームに回動可能に枢支するようにし、Ｘ方向送り枠により回動機構を介して回動フレームを正面視にて、時計方向又は反時計方向に回動するようにしてある。 That is, in this type of cap frame device, a plurality of rollers and regulating blocks provided on the main body frame side are engaged with roller grooves formed on the inner peripheral surface of the rotating frame from the inside, and the rotating frame is The main body frame is pivotally supported, and the rotation frame is rotated clockwise or counterclockwise in a front view via a rotation mechanism by an X-direction feed frame.
この場合、本体フレームには、シリンダベッドの上面を摺動可能な摺動部材が設けてあり、その摺動部材をシリンダベッドの上面に常に当接させることで、本体フレームの前端部を摺動部材を介して支持するようにし、本体フレームのシリンダベッドに対する高さ位置を所定の高さに保持し、本体フレーム及びこれに連結される回動フレームの姿勢が正規の鉛直姿勢となるように規制するようにしてある。 In this case, the main body frame is provided with a sliding member capable of sliding on the upper surface of the cylinder bed, and the front end portion of the main body frame is slid by always contacting the sliding member with the upper surface of the cylinder bed. The body frame is supported by a member, the height position of the main body frame with respect to the cylinder bed is maintained at a predetermined height, and the posture of the main body frame and the rotating frame connected to the main body frame is regulated to be a normal vertical posture. I have to do it.
そこで、鍔付き帽子の前面部や側面部に各種の刺繍を施す場合には、先ず、回動フレームを回動可能に支持する本体フレームを、刺繍ミシンのＹ方向駆動系に連結させるとともに、回動機構をＸ方向駆動系に連結する。そして、予め鍔付き帽子をセットした帽子枠を回動フレームに装着する。そして、最終的に選択した刺繍模様の刺繍縫目が鍔付き帽子の前面部や側面部に形成される。 Therefore, when various kinds of embroidery are applied to the front and side portions of the hat with a hook, first, the main body frame that rotatably supports the rotation frame is connected to the Y-direction drive system of the embroidery sewing machine, and the rotation is performed. The moving mechanism is connected to the X-direction drive system. And the hat frame which set the hat with a hook beforehand is mounted | worn with a rotation frame. And the embroidery stitch of the finally selected embroidery pattern is formed in the front part and side part of a hat with a hook.
このように、帽子枠を回動フレームに装着した場合、刺帽子枠装置の前端部分が重くなり、鍔付き帽子をセットした帽子枠の荷重が回動フレームに直接的に作用するため、ベースフレームに設けられたローラや規制ブロック等の弾性変形、更にはこれらローラや規制ブロックの接触部に対するローラ溝との微小隙間等により、回動フレームが若干ではあるが前傾姿勢、つまり回動フレームがシリンダベッドに対して側面視にて前方にお辞儀をする前傾姿勢になる。 In this way, when the hat frame is mounted on the rotating frame, the front end portion of the stab hat frame device becomes heavy, and the load of the hat frame on which the hat with the hook is set directly acts on the rotating frame. Due to the elastic deformation of the rollers and regulating blocks provided on the roller, and the minute gap between the roller grooves and the contact portions of these rollers and regulating blocks, the rotating frame is slightly tilted forward, that is, the rotating frame is It becomes a forward leaning posture of bowing forward in a side view with respect to the cylinder bed.
このように、回動フレームが前傾姿勢になった場合、回動フレーム及び帽子枠の上端部とその下側のシリンダベッドの上面との隙間が少ないことから、回動フレームや帽子枠がシリンダベッドに干渉する可能性があるだけでなく、帽子枠装置の前後方向への移動に伴って、回動フレームが上下に振動するようになり、縫製途中において、刺繍縫目が不良になったり、糸切れが発生する場合がある。 Thus, when the rotating frame is in a forward tilted posture, the clearance between the upper ends of the rotating frame and the cap frame and the upper surface of the cylinder bed below the rotating frame and the cap frame is small. In addition to the possibility of interfering with the bed, as the hat frame device moves in the front-rear direction, the rotating frame starts to vibrate up and down, and the embroidery stitch becomes defective during sewing, Thread breakage may occur.
そこで、作業者は、回動フレームの前傾姿勢の度合いに応じて、摺動部材の下側に薄い滑りシートを２〜５枚を挿入することで、本体フレームの前端部の高さ位置を高くして本体フレームを鉛直姿勢から、鉛直姿勢に対して前傾姿勢とは逆の後傾姿勢（仰向き姿勢）に姿勢を切換えるようにして、回動フレームを前傾姿勢から鉛直姿勢、つまり正規の姿勢に戻すようにしている。 Therefore, the operator inserts 2 to 5 thin sliding sheets on the lower side of the sliding member according to the degree of the forward tilting posture of the rotating frame, thereby setting the height position of the front end portion of the main body frame. The body frame is switched from a vertical posture to a backward tilt posture (upward posture) that is opposite to the forward tilt posture with respect to the vertical posture, and the rotating frame is changed from the forward tilt posture to the vertical posture, that is, normal. I try to return to the posture.
前述したように、特許第３１６９０４３号公報に記載の帽子枠装置を刺繍ミシンのＹ方向送り枠とＸ方向送り枠とに装着し、回動フレームに帽子枠を装着した場合に、回動フレームの姿勢が前傾姿勢となるのを、複数枚の滑りシートを摺動部材の下側に挿入して、本体フレームの前端部の高さ位置を高くする場合、挿入する滑りシートの枚数を徐々に増やす等の試行錯誤を繰り返すようにして、回動フレームの姿勢を正規の姿勢に戻すようにしているため、回動フレームの姿勢調節作業が非常に複雑化すること、縫製作業の準備作業に多大に時間を必要になるという問題がある。 As described above, when the cap frame device described in Japanese Patent No. 3169043 is mounted on the Y-direction feed frame and the X-direction feed frame of the embroidery sewing machine and the cap frame is mounted on the rotary frame, When the posture becomes the forward leaning posture, when inserting a plurality of sliding sheets below the sliding member and increasing the height position of the front end of the main body frame, gradually increase the number of sliding sheets to be inserted. Repeating the trial and error, such as increasing the number, the posture of the rotating frame is returned to the normal posture, so that the posture adjustment work of the rotating frame becomes very complicated, and the preparation work for the sewing work is great. There is a problem that it takes time.
請求項１の姿勢規制機構は、刺繍ミシンのＹ方向駆動系に連結される本体フレームと、その本体フレームに設けられ刺繍ミシンのシリンダベッドの上面を摺動する摺動部材と、本体フレームに回動可能に枢支される回動フレームと、刺繍ミシンのＸ方向駆動系に連結され回動フレームを回動させる回動機構と、回動フレームに装着される帽子枠とを備えた帽子枠装置に設けられ、シリンダベッドに対する回動フレームの姿勢を規制する姿勢規制機構であって、下端に摺動部材が固着され、本体フレームに上下移動可能に支持されて回動フレームのシリンダベッドに対する姿勢が正規の姿勢となるように規制する姿勢調節部材と、本体フレームの回動フレームよりも上方に突出させた突出壁部に形成され姿勢調節部材の高さ位置を調節可能な長穴と、本体フレームの長穴を介して姿勢調節部材を本体フレームに上下位置調節可能に締結する締結部材とを備えたものである。 The posture regulating mechanism according to claim 1 includes a main body frame coupled to the Y-direction drive system of the embroidery sewing machine, a sliding member provided on the main body frame and sliding on the upper surface of the cylinder bed of the embroidery sewing machine, and a rotation to the main body frame. A hat frame device comprising: a pivot frame that is pivotally supported; a pivot mechanism that is coupled to the X-direction drive system of the embroidery sewing machine; and a hat frame that is attached to the pivot frame. Is a posture regulating mechanism for regulating the posture of the rotating frame with respect to the cylinder bed, the sliding member being fixed to the lower end, and supported by the main body frame so as to be movable up and down, so that the posture of the rotating frame with respect to the cylinder bed is A posture adjustment member that regulates the posture to a normal posture and a length that can be adjusted to adjust the height position of the posture adjustment member that is formed on the protruding wall that protrudes above the pivot frame of the main body frame. When, in which a fastening member for fastening the attitude adjustment member through the long hole of the main frame adjustably vertically positioned on the body frame.
本体フレームを刺繍ミシンのＹ方向駆動系に連結し、回動機構を介して回動フレームをＸ方向駆動系に連結した場合、本体フレームに設けられた姿勢調節部材は、本体フレームの突出壁部に形成された長穴を介して上下移動可能に支持され、本体フレームに設けられた摺動部材は刺繍ミシンのシリンダベッドの上面に当接している。 When the main body frame is connected to the Y-direction drive system of the embroidery sewing machine and the rotation frame is connected to the X-direction drive system via the rotation mechanism, the posture adjusting member provided on the main body frame is a protruding wall portion of the main body frame. A sliding member provided on the main body frame is in contact with the upper surface of the cylinder bed of the embroidery sewing machine.
鍔付き帽子を回動フレームに装着した場合、刺帽子枠装置の前端部分が重くなり、鍔付き帽子をセットした帽子枠の荷重が回動フレームに直接的に作用するため、本体フレームの姿勢が正規の鉛直姿勢であっても、回動フレームを回動可能に枢支するように本体フレームに設けられたローラや規制ブロック等の弾性変形、更にはこれらローラや規制ブロックの接触部に対する回動フレームの内周面に形成されたローラ溝との微小隙間等により、回動フレームが若干ではあるが前傾姿勢（前方にお辞儀をする前傾姿勢）になる。 When the hat with a hook is attached to the rotating frame, the front end of the stab hat frame device becomes heavy, and the load of the hat frame with the hat with the hook is directly applied to the rotating frame. Even in the normal vertical posture, the elastic deformation of the roller and the restriction block provided on the main body frame so as to pivotally support the rotation frame, and further, the rotation of the roller and the restriction block with respect to the contact portion Due to a minute gap with the roller groove formed on the inner peripheral surface of the frame, the rotating frame is slightly forward tilted (forward tilted to bow forward).
ここで、作業者は、姿勢調節部材を本体フレームに締結している締結部材を緩めて、姿勢調節部材を本体フレームに対して押し下げた場合、その反作用で本体フレームの前端部が持ち上げる。この場合、摺動部材をシリンダベッドの上面に強く押圧した状態であるため、本体フレームはＹ方向駆動系との連結部を揺動支点として、鉛直姿勢から、鉛直姿勢に対して前傾姿勢とは逆の後傾姿勢（仰向き姿勢）に規制される。即ち、本体フレームの後傾姿勢を介して、回動フレームは前傾姿勢から鉛直姿勢である正規の姿勢に規制される。その後、作業者は締結部材により姿勢調節部材を本体フレームに締結する。 Here, when the operator loosens the fastening member that fastens the posture adjusting member to the main body frame and pushes the posture adjusting member down against the main body frame, the front end portion of the main body frame is lifted by the reaction. In this case, since the sliding member is strongly pressed against the upper surface of the cylinder bed, the main body frame has a forward tilting posture with respect to the vertical posture from the vertical posture with the connecting portion with the Y-direction drive system as a swing fulcrum. Is regulated to the reverse backward tilted posture (upright posture). That is, the rotation frame is regulated from the forward tilt posture to the normal posture which is the vertical posture through the rear tilt posture of the main body frame. Thereafter, the operator fastens the posture adjusting member to the main body frame with the fastening member.
ここで、前記本体フレームの突出壁部はシリンダベッドと直交状に設けられ、締結部材は締結ボルトからなり、その締結ボルトをシリンダベッドの長さ方向と平行な前方から締結操作可能に構成された場合（請求項１に従属の請求項２）には、突出壁部はシリンダベッドと直交状であって正面向きであり、しかも突出壁部の長穴を介して姿勢調節部材を本体フレームに締結する締結ボルトを、ドライバ等を用いて前方から締結したり、その締結を解除できる。 Here, the protruding wall portion of the main body frame is provided orthogonal to the cylinder bed, the fastening member is formed of a fastening bolt, and the fastening bolt is configured to be fastened from the front parallel to the length direction of the cylinder bed. In the case (Claim 2 dependent on Claim 1), the protruding wall portion is orthogonal to the cylinder bed and faces the front, and the posture adjusting member is fastened to the main body frame through the elongated hole of the protruding wall portion. The fastening bolt to be fastened can be fastened from the front using a screwdriver or the like, or the fastening can be released.
ここで、前記本体フレームは、回動フレームを回動可能に支持するベースフレームと、Ｙ方向駆動系に連結される連結フレームとからなり、ベースフレームは連結フレームに上下位置調節可能に締結部材により締結されている場合（請求項１又は２に従属の請求項３）には、ベースフレームを連結フレームに締結している締結部材を緩めることで、ベースフレームに回動可能に支持されている回動フレームの高さ位置を、シリンダベッドに対して正規の高さ位置に調節できる。 Here, the main body frame includes a base frame that rotatably supports the rotating frame, and a connecting frame that is connected to the Y-direction drive system, and the base frame can be adjusted vertically by a fastening member. When fastened (claim 3 dependent on claim 1 or 2), the fastening member fastening the base frame to the connecting frame is loosened to turn the base frame rotatably. The height position of the moving frame can be adjusted to a normal height position with respect to the cylinder bed.

And a hat frame 34 that is detachably attached to the head.
先ず、Ｙ方向送り枠１９とＸ方向送り枠２０に連結される本体フレーム３１と、この本体フレーム３１に連結される回動フレーム３２について説明する。
図２〜図４に示すように、本体フレーム３１は、所定の板厚を有するベースフレーム３６と、このベースフレーム３６に固定され、Ｙ方向送り枠１９に連結する連結フレーム３７とを有している。
First, the main body frame 31 connected to the Y-direction feed frame 19 and the X-direction feed frame 20 and the rotating frame 32 connected to the main body frame 31 will be described.
As shown in FIGS. 2 to 4, the main body frame 31 includes a base frame 36 having a predetermined plate thickness, and a connecting frame 37 fixed to the base frame 36 and connected to the Y-direction feed frame 19. Yes.
ベースフレーム３６は、シリンダベッド６の通過を許容する矩形状の切欠き３６ａが形成されるとともに、三角形状にくり抜いて軽量化されている。ベースフレーム３６には、回動フレーム３２を回動自在に支持する３つのローラ３８が回転可能に枢着されるとともに、回動フレーム３２の前後方向位置を回転可能に規制する規制ブロック３９が２カ所に固定されている。 The base frame 36 is formed with a rectangular cutout 36 a that allows passage of the cylinder bed 6, and is lightened by being cut out in a triangular shape. Three rollers 38 that rotatably support the rotating frame 32 are rotatably attached to the base frame 36, and two restriction blocks 39 that restrict the position of the rotating frame 32 in the front-rear direction are rotatable. It is fixed in place.
連結フレーム３７は、図５に示すように、ベースフレーム３６の切欠き３６ａに対応する切欠き穴３７ａを形成した取付け壁部３７ｂと、この取付け壁部３７ｂの左右端部から夫々後方に折曲げられた折曲げ壁部３７ｃと、これら折曲げ壁部３７ｃの上端部を水平状に外側に折り曲げたＹ方向連結部３７ｄが夫々形成され、これら左右１対のＹ方向連結部３７ｄを、Ｙ方向送り枠１９にボルト２１にて固定した左右１対のＹ方向駆動板２２に、上向きのツマミ付きボルト４０にて着脱可能に連結することで、本体フレーム３１はＹ方向送り枠１９と連結され、Ｙ方向送り枠１９と一体的に前後方向に移動可能である。 As shown in FIG. 5, the connecting frame 37 is bent rearward from a mounting wall portion 37b formed with a notch hole 37a corresponding to the notch 36a of the base frame 36, and left and right end portions of the mounting wall portion 37b. The bent wall portions 37c and the Y direction connecting portions 37d obtained by horizontally bending the upper ends of the bent wall portions 37c outwardly are formed, and the pair of left and right Y direction connecting portions 37d are connected to the Y direction. The main body frame 31 is connected to the Y-direction feed frame 19 by detachably connecting to a pair of left and right Y-direction drive plates 22 fixed to the feed frame 19 with bolts 21 with bolts 40 with an upward knob. The Y-direction feed frame 19 can be moved integrally in the front-rear direction.
ここで、左右１対のＹ方向駆動板２２は、図２に示すように、シリンダベッド６に対して左右両側において１対のＹ方向連結部３７ｄに対応させて設けられている。しかも、各Ｙ方向駆動板２２の先端部分には、前方開放状（Ｙ字状）の連結用切欠き２２ａが形成され、Ｙ方向連結部３７ｄに螺合されたツマミ付きボルト４０のネジ部を、これら連結用切欠き２２ａに挿入し易くなっている。 Here, as shown in FIG. 2, the pair of left and right Y-direction drive plates 22 are provided corresponding to the pair of Y-direction connecting portions 37 d on the left and right sides of the cylinder bed 6. Moreover, a front opening (Y-shaped) connection notch 22a is formed at the tip of each Y-direction drive plate 22, and the screw portion of the bolt 40 with the knob screwed into the Y-direction connection portion 37d is provided. These can be easily inserted into the connecting cutouts 22a.
ベースフレーム３６は、更に、４本の締結ボルト４１により連結フレーム３７の取付け壁部３７ｂに、高さ位置調節可能に固定されている。即ち、ベースフレーム３６に形成されたボルト挿通穴は縦長に形成されているため、これら締結ボルト４１を緩めた場合、これら縦長のボルト挿通穴を介して、ベースフレーム３６の連結フレーム３７に対する高さ位置つまり回動フレーム３２の連結フレーム３７に対する高さ位置が調節可能になっている。 The base frame 36 is further fixed to the mounting wall portion 37b of the connecting frame 37 by four fastening bolts 41 so that the height position can be adjusted. That is, since the bolt insertion holes formed in the base frame 36 are formed in a vertically long shape, when the fastening bolts 41 are loosened, the height of the base frame 36 with respect to the connecting frame 37 via the vertically long bolt insertion holes. The position, that is, the height position of the rotating frame 32 with respect to the connecting frame 37 can be adjusted.
また、取付け壁部３７ｂの切欠き穴３７ａの上側の部位には、所定幅に亙って上方に延びる突出壁部３７ｅが形成され、その突出壁部３７ｅの上端部を前方に折曲げた水平壁部３７ｆが形成されている。ここで、突出壁部３７ｅの後側には、図２、図４、図５に示すように、鉛直壁部４２ａと後方向きの水平壁部４２ｂとからなるＬ字状に形成された合成樹脂製の抜止め防止ブラケット４２がビスにより固定され、後述する可動部材５０が、これら水平壁部３７ｆ，４２ｂにより帽子枠装置３０から外れないようになっている。 In addition, a protruding wall portion 37e extending upward over a predetermined width is formed at a portion above the notch hole 37a of the mounting wall portion 37b, and a horizontal portion in which the upper end portion of the protruding wall portion 37e is bent forward. A wall portion 37f is formed. Here, on the rear side of the protruding wall portion 37e, as shown in FIGS. 2, 4, and 5, a synthetic resin formed in an L shape including a vertical wall portion 42a and a rearward facing horizontal wall portion 42b. A made-out prevention bracket 42 is fixed with screws, and a movable member 50 described later is prevented from being detached from the cap frame device 30 by these horizontal wall portions 37f and 42b.
図２、図４に示すように、回動フレーム３２の外周部には、ワイヤ５１を導く環状のワイヤ案内溝４４が形成され、さらに、図２、図３に示すように、回動フレーム３２の外周部には、回動フレーム３２の前端側部分に帽子枠３４を外嵌状に装着した際に、帽子枠３４の係合穴７３に係合し、帽子枠３４を回動フレーム３２に一体的に連結する複数の係合ローラ４５が設けられている。回動フレーム３２の内周面には、本体フレーム３１側の２つのローラ３８と２つの規制ブロック３９が係合する環状のローラ溝３２ａ（図６参照）が形成されている。 As shown in FIGS. 2 and 4, an annular wire guide groove 44 for guiding the wire 51 is formed on the outer peripheral portion of the rotating frame 32, and further, as shown in FIGS. 2 and 3, the rotating frame 32. When the cap frame 34 is externally fitted to the front end side portion of the rotating frame 32, the cap frame 34 is engaged with the engaging hole 73 of the cap frame 34. A plurality of engaging rollers 45 that are integrally connected are provided. An annular roller groove 32a (see FIG. 6) in which the two rollers 38 on the main body frame 31 side and the two restriction blocks 39 are engaged is formed on the inner peripheral surface of the rotating frame 32.
次に、回動機構３３について説明する。図２〜図４に示すように、回動機構３３は、本体フレーム３１に対して左右方向に相対移動可能にＸ方向送り枠２０に連結された左右に細長い可動部材５０と、ワイヤ案内溝４４において回動フレーム３２に巻き付けられ且つその両端が可動部材５０の両端側部分に夫々連結されたワイヤ５１とを備えている。 Next, the rotation mechanism 33 will be described. As shown in FIGS. 2 to 4, the rotation mechanism 33 includes a movable member 50 that is elongated to the left and right connected to the X-direction feed frame 20 so as to be movable relative to the main body frame 31 in the left-right direction, and a wire guide groove 44. The wire 51 is wound around the rotating frame 32 and both ends thereof are connected to both end portions of the movable member 50, respectively.
図２、図３に示すように、可動部材５０の後端部の左右両端部には２つの固定穴（図示略）が形成され、可動部材５０の後端部をＸ方向送り枠２０の前端部に当接させた状態で、２つの固定穴を挿通させた下向きのツマミ付きボルト５２によりＸ方向送り枠２０に螺着することで、可動部材５０はＸ方向送り枠２０に連結される。 As shown in FIGS. 2 and 3, two fixing holes (not shown) are formed at the left and right ends of the rear end of the movable member 50, and the rear end of the movable member 50 is used as the front end of the X-direction feed frame 20. The movable member 50 is coupled to the X-direction feed frame 20 by being screwed to the X-direction feed frame 20 by a downward-facing knob-attached bolt 52 through which the two fixing holes are inserted while being in contact with the portion.
図２、図４に示すように、可動部材５０の前後方向中央部には、左右方向に延びる矩形状の切欠き５０ａが形成され、この切欠き５０ａを、連結フレーム３７の突出壁部３７ｅ及び抜止め防止ブラケット４２が挿通しているため、可動部材５０はＸ方向送り枠２０と一体的に且つ本体フレーム３１に対して相対的に左右方向へ移動可能であるとともに、帽子枠装置３０から外れないようになっている。 As shown in FIGS. 2 and 4, a rectangular notch 50 a extending in the left-right direction is formed at the center in the front-rear direction of the movable member 50, and the notch 50 a is connected to the protruding wall portion 37 e of the connecting frame 37 and Since the retaining bracket 42 is inserted, the movable member 50 can move in the left-right direction integrally with the X-direction feed frame 20 and relatively with respect to the main body frame 31, and is detached from the cap frame device 30. There is no such thing.
可動部材５０の下側において、回動フレーム３２から左方へ延びるワイヤ５１の一端は、可動部材５０の左端部の下側に設けられたワイヤ連結部材５３に連結され、このワイヤ連結部材５３が左右方向位置調節可能に可動部材５０にビス止めされている。一方、可動部材５０の下側において、回動フレーム３２から右方へ延びるワイヤ５１は、可動部材５０の右端部分の下側でビス止め固定されている。 On the lower side of the movable member 50, one end of the wire 51 extending leftward from the rotating frame 32 is coupled to a wire coupling member 53 provided on the lower side of the left end portion of the movable member 50, and the wire coupling member 53 is Screwed to the movable member 50 so that the position in the left-right direction can be adjusted. On the other hand, on the lower side of the movable member 50, the wire 51 extending rightward from the rotating frame 32 is screwed and fixed on the lower side of the right end portion of the movable member 50.
それ故、Ｘ方向送り枠２０がＹ方向送り枠１９に対して左右方向に移動駆動されると、可動部材５０が本体フレーム３１に対してＸ方向送り枠２０と一体的に左右方向に移動する。このとき、可動部材５０の両端側部分にその両端が連結されたワイヤ５１も左右に移動するため、回動フレーム３２が複数のローラ３８を介して、正面視にて時計回り又は反時計回りに所定角度回動することになる。 Therefore, when the X-direction feed frame 20 is driven to move in the left-right direction with respect to the Y-direction feed frame 19, the movable member 50 moves integrally with the X-direction feed frame 20 in the left-right direction with respect to the main body frame 31. . At this time, since the wire 51 having both ends connected to the both end portions of the movable member 50 also moves left and right, the rotating frame 32 is rotated clockwise or counterclockwise through the plurality of rollers 38 in front view. It will rotate a predetermined angle.
次に、連結フレーム３７の左右両端部に形成された１対のＹ方向連結部３７ｄ間に架着された姿勢規制部材５５について、図２，図３，図５に基づいて説明する。
姿勢規制部材５５は、前後方向に所定幅を有し左右に細長い板状の部材であり、その左右両端部の固定部５５ａにおいて、Ｙ方向連結部３７ｄに夫々ビス５６により固定されている。姿勢規制部材５５の左右方向中央部分は、複数の折り曲げにより、それら固定部５５ａよりも低く位置するように平坦状の当接部５５ｂが形成されている。
Next, the attitude regulating member 55 attached between the pair of Y-direction coupling portions 37d formed at the left and right ends of the coupling frame 37 will be described with reference to FIGS.
The posture regulating member 55 is a plate-like member that has a predetermined width in the front-rear direction and is elongated to the left and right, and is fixed to the Y-direction connecting portion 37d by screws 56 at fixing portions 55a at both left and right ends thereof. A flat contact portion 55b is formed at the center portion in the left-right direction of the posture regulating member 55 so as to be positioned lower than the fixed portions 55a by a plurality of bends.
その当接部５５ｂは、本体フレーム３１をＹ方向駆動板２２に連結する際には、シリンダベッド６の平坦な上面に面接触状に当接するように、所定長さに亙って平坦状になっている。その当接部５５ｂには、更に、後方に所定長さだけ延出させた延出部５５ｄが一体形成されている。 The abutment portion 55b is flat over a predetermined length so as to abut on the flat upper surface of the cylinder bed 6 in surface contact when the main body frame 31 is connected to the Y-direction drive plate 22. It has become. The contact portion 55b is further integrally formed with an extension portion 55d that extends backward by a predetermined length.
即ち、本体フレーム３１をＹ方向駆動板２２に連結する際には、摺動部材６２と、延出部５５ｄを含む当接部５５ｂとを同時に、シリンダベッド６の平坦な上面に面接触状に当接させた場合、本体フレーム３１の鉛直姿勢が所定の取付け姿勢に規制されるとともに、シリンダベッド６と平行な水平軸回りの本体フレーム３１の回動姿勢が所定の取付け姿勢に規制される。 That is, when the main body frame 31 is connected to the Y-direction drive plate 22, the sliding member 62 and the abutting portion 55b including the extending portion 55d are simultaneously brought into surface contact with the flat upper surface of the cylinder bed 6. In the case of contact, the vertical posture of the main body frame 31 is regulated to a predetermined mounting posture, and the turning posture of the main body frame 31 around the horizontal axis parallel to the cylinder bed 6 is restricted to the predetermined mounting posture.
次に、前述した突出壁部３７ｅと水平壁部３７ｆを用いて、シリンダベッド６に対する回動フレーム３２の姿勢を規制する姿勢規制機構６０について、図２〜図６に基づいて説明する。 Next, a posture regulating mechanism 60 that regulates the posture of the rotating frame 32 with respect to the cylinder bed 6 using the protruding wall portion 37e and the horizontal wall portion 37f described above will be described with reference to FIGS.
この姿勢規制機構６０について説明すると、刺繍ミシンに装着した回動フレーム３２に、鍔付き帽子６６をセットした帽子枠３４を取付けた場合、帽子枠装置３０の前端部分が重くなり、ベースフレーム３６に設けられたローラや３８や規制ブロック３９の弾性変形、更にはこれらローラや３８や規制ブロック３９の接触部に対するローラ溝３２ａとの微小隙間等により、回動フレーム３２が若干ではあるが前傾姿勢、つまり回動フレーム３２がシリンダベッド６に対して側面視にて前方にお辞儀をする前傾姿勢になるのを、鉛直状態である正規の姿勢に規制（修正）できるようになっている。 The posture restriction mechanism 60 will be described. When the hat frame 34 with the hooked cap 66 is attached to the rotating frame 32 attached to the embroidery sewing machine, the front end portion of the hat frame device 30 becomes heavy, and the base frame 36 is attached. The rotating frame 32 is slightly inclined forward due to the elastic deformation of the rollers 38 and the restriction block 39 provided, and the minute gap with the roller groove 32a with respect to the contact portions of these rollers 38 and the restriction block 39. That is, the rotation frame 32 can be restricted (corrected) to a normal posture in a vertical state from the forward tilted posture of bowing forward with respect to the cylinder bed 6 in a side view.
連結フレーム３７の突出壁部３７ｅの左右方向中央部の後側に、側面視コ字状の姿勢調節部材６１が配設され、抜止め防止ブラケット４２により後側から上下移動可能に支持されている。この姿勢調節部材６１の下端部を前方に折曲げ形成された下壁６１ａの下面に、ブロック状の摺動部材６２の上端面が接着材等で貼着されている。 A laterally U-shaped posture adjusting member 61 is disposed on the rear side of the central portion in the left-right direction of the protruding wall portion 37e of the connection frame 37, and is supported by the retaining bracket 42 so as to be vertically movable from the rear side. . The upper end surface of the block-shaped sliding member 62 is adhered to the lower surface of the lower wall 61a formed by bending the lower end portion of the posture adjusting member 61 forward with an adhesive or the like.
この摺動部材６２は、低摩擦係数を有し且つ耐摩耗性からなる部材で構成され、本体フレーム３１をＹ方向駆動板２２に連結する際に、本体フレーム３１がその摺動部材６２を介してシリンダベッド６の上面を円滑にＹ方向に摺動可能になっている。姿勢調節部材６１の上壁６１ｂと下壁６１ａを連結する鉛直且つ左右向きの連結壁６１ｃには、雌ネジを形成したボルト穴が左右２カ所に形成されている。 The sliding member 62 is composed of a member having a low friction coefficient and having wear resistance. When the main body frame 31 is connected to the Y-direction drive plate 22, the main body frame 31 is interposed via the sliding member 62. Thus, the upper surface of the cylinder bed 6 can be smoothly slid in the Y direction. Bolt holes formed with female screws are formed at two left and right positions on the vertical and left-right connecting wall 61c that connects the upper wall 61b and the lower wall 61a of the posture adjusting member 61.
突出壁部３７ｅには、姿勢調節部材６１の２つのボルト穴に対応するように、縦方向に長い長穴３７ｇが夫々形成されている。そこで、２本の締結ボルト６３が長穴３７ｇを挿通して連結壁６１ｃのボルト穴に夫々螺着されている。それ故、これら２本の締結ボルト６３を前方から締結操作が可能であり、刺繍ミシンＭ２の前方からドライバでこれら締結ボルト６３を緩めることで、姿勢調節部材６１が、長穴３７ｇを介して連結フレーム３７（本体フレーム３１）に対して上下位置調節可能になっている。 In the protruding wall portion 37e, long holes 37g that are long in the vertical direction are formed so as to correspond to the two bolt holes of the posture adjusting member 61, respectively. Therefore, the two fastening bolts 63 are inserted into the elongated holes 37g and screwed into the bolt holes of the connecting wall 61c. Therefore, these two fastening bolts 63 can be fastened from the front. By loosening these fastening bolts 63 with a screwdriver from the front of the embroidery sewing machine M2, the posture adjusting member 61 is connected via the elongated hole 37g. The vertical position can be adjusted with respect to the frame 37 (main body frame 31).
姿勢調節部材６１を本体フレーム３１に対して押し下げた場合、本体フレーム３１は、Ｙ方向連結部３７ｄを揺動支点として、摺動部材６２とシリンダベッド６の上面との接触を介してその反力により、持ち上がるようになる（図６参照）。逆に、姿勢調節部材６１を本体フレーム３１に対して押し上げた場合、本体フレーム３１は、Ｙ方向連結部３７ｄを揺動支点として、摺動部材６２を介して自重により、下がるようになる。 When the posture adjusting member 61 is pushed down with respect to the main body frame 31, the main body frame 31 uses the Y-direction connecting portion 37 d as a rocking fulcrum and the reaction force through contact between the sliding member 62 and the upper surface of the cylinder bed 6. As a result, it is lifted (see FIG. 6). Conversely, when the posture adjusting member 61 is pushed up with respect to the main body frame 31, the main body frame 31 is lowered by its own weight through the sliding member 62 with the Y-direction connecting portion 37 d as a swing fulcrum.
次に、帽子枠３４について、図２，図４に基づいて簡単に説明する。
帽子枠３４は、回動フレーム３２に着脱自在に装着される環状の帽子枠本体６５と、この帽子枠本体６５に一端が連結され帽子枠本体６５に鍔付き帽子６６を上側から挟んで着脱自在に固定される正面視にて湾曲状の押え枠部材６７と、鍔付き帽子６６の形状を内側から保持する形状保持部材６８とを有する。
Next, the cap frame 34 will be briefly described with reference to FIGS.
The cap frame 34 is detachably attached to an annular cap frame main body 65 that is detachably attached to the rotating frame 32, and one end of the cap frame main body 65 is connected to the cap frame main body 65 with a hooked cap 66 sandwiched from above. A presser frame member 67 that is curved when viewed from the front, and a shape holding member 68 that holds the shape of the hooked cap 66 from the inside.
帽子枠本体６５には、回動フレーム３２に外嵌される環状の取付け枠部７０と、取付け枠部７０に付設された鍔状部７１と、この鍔状部７１に固定されて取付け枠部７０の中央最上部から後方へ斜め上方に立ち上がり、鍔付き帽子６６の鍔部６６ａを支持する鍔支持体７２等が設けられている。取付け枠部７０には、回動フレーム３２に付設された２つの係合ローラ４５が夫々係合する２つの係合穴７３が形成され、４つの係合ローラ４５を対応する係合穴７３に夫々係合させることで、帽子枠３４が回動フレーム３２に着脱自在に固定される。 The cap frame main body 65 includes an annular mounting frame portion 70 fitted on the rotating frame 32, a hook-like portion 71 attached to the mounting frame portion 70, and an attachment frame portion fixed to the hook-like portion 71. A heel support 72 and the like that rise obliquely upward from the central uppermost portion of 70 and support the heel portion 66a of the hooded cap 66 are provided. The attachment frame portion 70 is formed with two engagement holes 73 with which the two engagement rollers 45 attached to the rotating frame 32 are engaged, and the four engagement rollers 45 are formed in the corresponding engagement holes 73. The cap frame 34 is detachably fixed to the rotating frame 32 by engaging with each other.
帽子枠本体６５には、鍔付き帽子６６の刺繍縫い部６６ｂの形状を湾曲状に且つ緩みのない状態に張るための平面視矩形枠状の形状保持部材６８の前端部が固定されている。鍔支持体７２の基部の前面には、鍔部６６ａの基端部の内面側中央部を後方から受け止める受け止め部材７４が固着されている。 To the hat frame main body 65, a front end portion of a shape holding member 68 having a rectangular frame shape in plan view for stretching the shape of the embroidery sewing portion 66b of the hat 66 with a hook in a curved shape without loosening is fixed. On the front surface of the base portion of the heel support 72, a receiving member 74 that fixes the inner surface side central portion of the base end portion of the heel portion 66a from behind is fixed.
次に、このように構成された帽子枠装置３０の作用について説明する。
先ず、作業用テーブル１５を下降位置に下降させてから、本体フレーム３１に形成した１対のＹ方向連結部３７ｄを、Ｙ方向送り枠１９の対応するＹ方向駆動板２２に夫々連結させる。この場合には、先ず、ベースフレーム３６の切欠き３６ａ及び連結フレーム３７の切欠き穴３７ａにシリンダベッド６の先端部を挿通させる。このとき、作業者は本体フレーム３１を下げ気味にして、手前側の摺動部材６２と、奥側の延出部５５ｄを含む当接部５５ｂを、シリンダベッド６の上面の平坦部分に載置させる。
Next, the operation of the hat frame device 30 configured as described above will be described.
First, the work table 15 is lowered to the lowered position, and then the pair of Y-direction connecting portions 37d formed on the main body frame 31 are connected to the corresponding Y-direction drive plates 22 of the Y-direction feed frame 19, respectively. In this case, first, the tip of the cylinder bed 6 is inserted into the notch 36 a of the base frame 36 and the notch hole 37 a of the connecting frame 37. At this time, the operator puts down the main body frame 31 and places the sliding member 62 on the near side and the abutting portion 55 b including the extending portion 55 d on the far side on the flat portion on the upper surface of the cylinder bed 6. Let
この場合、前述したように、平坦状の当接部５５ｂは左右方向に所定長さを有するとともに、延出部５５ｄは当接部５５ｂよりも後方に延出しているため、これら摺動部材６２と、延出部５５ｄを含む当接部５５ｂとにより、本体フレーム３１の鉛直姿勢が、所定の取付け姿勢に規制される。 In this case, as described above, the flat contact portion 55b has a predetermined length in the left-right direction, and the extension portion 55d extends rearward from the contact portion 55b. The vertical posture of the main body frame 31 is restricted to a predetermined mounting posture by the contact portion 55b including the extending portion 55d.
更に、これと同時に、その当接部５５ｂによるシリンダベッド６の上面に対する面接触状の当接を介して、シリンダベッド６と平行な水平軸回りの本体フレーム３１の回動姿勢についても所定の取付け姿勢に規制される。このように、本体フレーム３１の鉛直姿勢及び回動姿勢が所定の取付け姿勢に規制された場合、本体フレーム３１の１対のＹ方向連結部３７ｄの各々がＹ方向送り枠の１対のＹ方向駆動板２２の各々に対応する位置関係となる。 Further, at the same time, the rotation posture of the main body frame 31 around the horizontal axis parallel to the cylinder bed 6 is also determined by the predetermined attachment via the contact of the contact portion 55b with the upper surface of the cylinder bed 6 in a surface contact manner. Regulated by posture. As described above, when the vertical posture and the pivoting posture of the main body frame 31 are restricted to the predetermined mounting posture, each of the pair of Y-direction connecting portions 37d of the main body frame 31 corresponds to the pair of Y-directions of the Y-direction feed frame. The positional relationship corresponds to each of the drive plates 22.
それ故、作業者はこの所定の取付け姿勢を保持した状態で、本体フレーム３１をシリンダベッド６に沿って奥側にスライド移動させるだけで、Ｙ方向連結部３７ｄに予め螺合されたツマミ付きボルト４０のネジ部を、各Ｙ方向駆動板２２の先端部分に形成されたＹ字状の連結用切欠き２２ａに簡単に挿入させることができる。このとき、ツマミ付きボルト４０を締め込んで、Ｙ方向連結部３７ｄをＹ方向駆動板２２に簡単に連結することができる。 Therefore, the operator simply slides the main body frame 31 along the cylinder bed 6 in the state where the predetermined mounting posture is maintained, and the bolt with a knob screwed into the Y-direction connecting portion 37d in advance. The 40 screw portions can be easily inserted into the Y-shaped connecting cutouts 22 a formed at the tip portions of the respective Y-direction drive plates 22. At this time, the bolt 40 with knob can be tightened to easily connect the Y-direction connecting portion 37 d to the Y-direction drive plate 22.
その後、可動部材５０を、１対のツマミ付きボルト５２によりＸ方向送り枠２０に夫々締結する。これにより、本体フレーム３１の刺繍ミシンＭ１〜Ｍ３に対する連結作業が完了する。そこで、鍔付き帽子６６を予めセットした帽子枠３４を、回動フレーム３２に装着する。このとき、前述したように、回動フレーム３２が前傾姿勢に傾斜するので、最終的に、姿勢規制機構６０により、回動フレーム３２のシリンダベッド６に対する取付け姿勢を規制する。 Thereafter, the movable member 50 is fastened to the X-direction feed frame 20 by a pair of bolts 52 with knobs. Thereby, the connecting operation of the main body frame 31 to the embroidery sewing machines M1 to M3 is completed. Therefore, the hat frame 34 in which the hat 66 with the hook is set in advance is attached to the rotating frame 32. At this time, as described above, since the rotating frame 32 is inclined to the forward inclined posture, finally, the mounting posture of the rotating frame 32 with respect to the cylinder bed 6 is regulated by the posture regulating mechanism 60.
即ち、先ず、２本の締結ボルト６３をドライバ等を用いて前方から少しだけ緩める。このとき、姿勢調節部材６１は、その下端の摺動部材６２がシリンダベッド６の上面に当接するまで下降し、更に、回動フレーム３２及び本体フレーム３１が、長穴３７ｇを介してその自重で下がる。即ち、回動フレーム３２が、図４に２点鎖線で示すように、Ｙ方向連結部３７ｄを揺動支点として前傾姿勢に傾斜する。このとき、摺動部材６２はシリンダベッド６の上面に当接した状態である。 That is, first, the two fastening bolts 63 are slightly loosened from the front using a screwdriver or the like. At this time, the posture adjusting member 61 is lowered until the sliding member 62 at its lower end comes into contact with the upper surface of the cylinder bed 6, and the rotating frame 32 and the main body frame 31 are moved by their own weights through the long holes 37g. Go down. That is, as shown by a two-dot chain line in FIG. 4, the rotating frame 32 is inclined in a forward inclined posture with the Y-direction connecting portion 37d as a swing fulcrum. At this time, the sliding member 62 is in contact with the upper surface of the cylinder bed 6.
そこで、作業者は、姿勢調節部材６１を押し下げながらその反作用で連結フレーム３７の水平壁部３７ｆを徐々に持ち上げる。即ち、この場合、摺動部材６２をシリンダベッド６の上面に強く押圧した状態であるため、連結フレーム３７及びベースフレーム３６はＹ方向連結部３７ｄを揺動支点として、図６に２点鎖線で示すように、鉛直姿勢から、鉛直姿勢に対して前傾姿勢とは逆の後傾姿勢（仰向き姿勢）に規制されるので、この後傾姿勢を介して、回動フレーム３２は前傾姿勢から鉛直姿勢、つまり正規の姿勢に規制される。このとき、作業者はドライバ等で前方から２本の締結ボルト６３を締め込む。 Therefore, the operator gradually lifts the horizontal wall portion 37f of the connecting frame 37 by the reaction while pushing down the posture adjusting member 61. That is, in this case, since the sliding member 62 is strongly pressed against the upper surface of the cylinder bed 6, the connecting frame 37 and the base frame 36 are shown by a two-dot chain line in FIG. As shown in the figure, since the vertical posture is restricted to a backward inclined posture (upright posture) opposite to the forward inclined posture with respect to the vertical posture, the rotating frame 32 is moved from the forward inclined posture through the backward inclined posture. It is restricted to a vertical posture, that is, a normal posture. At this time, the operator tightens the two fastening bolts 63 from the front with a driver or the like.
ここで、回動フレーム３２の姿勢がこのような正規の姿勢となるように規制された場合、摺動部材６２がシリンダベッド６の上面に強く押圧された押圧状態を保持しながら、回動フレーム３２の正規の姿勢が保持される。それ故、刺繍縫いが実行されて、回動フレーム３２がＹ方向に移動する場合でも、回動フレーム３２の正規の姿勢は確実に保持される。更には、回動フレーム３２の何れの部位においてもシリンダベッド６に接触しないため、鍔付き帽子６６の刺繍縫い部６６ｂには、綺麗な縫目が形成される。 Here, when the posture of the rotating frame 32 is regulated so as to be in such a normal posture, the rotating frame 62 is held while the sliding member 62 is strongly pressed against the upper surface of the cylinder bed 6. 32 regular postures are maintained. Therefore, even when embroidery sewing is executed and the rotating frame 32 moves in the Y direction, the normal posture of the rotating frame 32 is reliably maintained. Further, since any part of the rotating frame 32 does not come into contact with the cylinder bed 6, a beautiful seam is formed in the embroidery sewing portion 66 b of the hooked cap 66.
一方、回動フレーム３２の姿勢が、このように正規の姿勢に規制された場合でも、ベースフレーム３６を連結フレーム３７に固定してある４本の締結ボルト４１を緩めることで、回動フレーム３２のシリンダベッド６に対する高さ位置、つまり上下位置を微調節できるようになっている。 On the other hand, even when the posture of the rotating frame 32 is restricted to the normal posture in this way, the rotating frame 32 is loosened by loosening the four fastening bolts 41 that fix the base frame 36 to the connecting frame 37. The height position of the cylinder bed 6, that is, the vertical position can be finely adjusted.
このように、姿勢調節部材６１と、突出壁部３７ｅに形成した長穴３７ｇと、姿勢調節部材６１を本体フレーム３１の連結フレーム３７に締結する締結ボルト６３とを設けたので、帽子枠３４を回動フレーム３２に装着した際に、回動フレーム３２の姿勢が前傾姿勢になった場合、締結ボルト６３を緩めて姿勢調節部材６１を本体フレーム３１に対して押し下げるだけで、摺動部材６２のシリンダベッド６上面への押圧を介して本体フレーム３１が鉛直姿勢から、鉛直姿勢に対して前傾姿勢とは逆の後傾姿勢（仰向き姿勢）に規制され、これに伴って、回動フレーム３２は前傾姿勢から鉛直姿勢である正規の姿勢に規制できるため、回動フレーム３２の正規の姿勢への規制（調節）作業を簡単化することができる。 As described above, the posture adjusting member 61, the long hole 37g formed in the protruding wall portion 37e, and the fastening bolt 63 for fastening the posture adjusting member 61 to the connecting frame 37 of the main body frame 31 are provided. When the rotary frame 32 is tilted forward when mounted on the rotary frame 32, the sliding member 62 can be obtained simply by loosening the fastening bolt 63 and pushing down the posture adjusting member 61 against the main body frame 31. The main body frame 31 is restricted from a vertical posture to a backward inclined posture (upright posture) opposite to the forward inclined posture with respect to the vertical posture through the pressure on the upper surface of the cylinder bed 6. Since 32 can be regulated from a forward tilting posture to a normal posture which is a vertical posture, the restriction (adjustment) work of the rotating frame 32 to the normal posture can be simplified.
また、姿勢調節部材６１の押し下げ操作を作業者の片手で行うことができるため、操作性を高めることができる。しかも、突出壁部３７ｅに長穴３７ｇを形成し、姿勢調節部材６１と、姿勢調節部材６１を本体フレーム３１に締結する締結ボルト６３とを設けただけなので、姿勢規制機構６０の構造を簡単化することができる。 Further, since the pressing operation of the posture adjusting member 61 can be performed with one hand of the operator, the operability can be improved. Moreover, since the elongated hole 37g is formed in the protruding wall portion 37e and only the posture adjusting member 61 and the fastening bolt 63 for fastening the posture adjusting member 61 to the main body frame 31 are provided, the structure of the posture regulating mechanism 60 is simplified. can do.
また、本体フレーム３１の突出壁部３７ｅはシリンダベッド６と直交状に設けられ、締結部材は締結ボルト６３からなり、その締結ボルト６３をシリンダベッド６の長さ方向と平行な前方から締結操作可能に構成されたので、ドライバ等を用いて前方から締結操作が可能であるため、締結操作の操作性や作業性を高めることができる。 Further, the projecting wall portion 37e of the main body frame 31 is provided orthogonal to the cylinder bed 6 and the fastening member is composed of a fastening bolt 63. The fastening bolt 63 can be fastened from the front parallel to the length direction of the cylinder bed 6. Since the fastening operation can be performed from the front using a driver or the like, the operability and workability of the fastening operation can be improved.
