Description

本発明は、合成樹脂製嵌合用部材の貫通孔に挿入した合成樹脂製リベット部材の突起を打込み具により打撃して、突起先端部を拡径変形(フランジ付け)することにより、リベット部材と嵌合用部材とをシート状部材を挟んだ状態にカシメ止めするようにしたスナップファスナー取付け機のうち、合成樹脂製のリベット部材を突起が上向きになるように支持する受け具と、その上方に受け具と対向して配置された昇降自在な打込み具と、中央にリベット部材の突起を挿通するための貫通孔が形成された合成樹脂製の嵌合用部材を収容する第1ホッパーと、リベット部材を収容する第2ホッパーと、第1ホッパーから繰り出された嵌合用部材を流下供給する第1シュートと、第2ホッパーから繰り出されたリベット部材を流下供給する第2シュートと、第1シュートの下端まで流下供給された嵌合用部材を前記打込み具に、第2シュートの下端まで流下供給されたリベット部材を前記受け具に、夫々、送り込む上下二段の押圧用板部を有する前後方向に往復移動可能なプッシャーと、打込み具の昇降駆動手段と、プッシャーの駆動手段とを備え、前記打込み具は、昇降駆動手段によって駆動される昇降自在な打込み具本体と、打込み具本体に上下方向スライド自在に装着された嵌合用部材保持用の開閉自在な上部チャックと、打込み具本体に対して上下方向スライド自在で且つ付勢手段により下方へ付勢された筒軸状のガイドパンチと、ガイドパンチの内側に配置され且つ打込み具本体に対して固定されたカシメパンチとを備え、前記受け具は、リベット部材を載置する受け台と、打込み具の下降と所定のタイミングで同期して下降するように構成されたシート状部材位置決め用の開閉自在な下部チャックとを備え、前記受け具と前記打込み具との間にシート状部材を介在させた状態で、打込み具を下降させることにより、前記ガイドパンチで嵌合部材を押し下げて、リベット部材の突起をシート状部材に突き刺すと共に嵌合部材の貫通孔に挿入し、前記カシメパンチで突起先端部を打撃して拡径変形させ、前記リベット部材と前記嵌合用部材とをシート状部材を挟んだ状態にカシメ止めするようにしたスナップファスナー取付け機に関するものである。   According to the present invention, the protrusion of the synthetic resin rivet member inserted into the through hole of the synthetic resin fitting member is struck with a driving tool, and the protrusion tip is expanded and deformed (flanged), thereby fitting with the rivet member. Of the snap fastener attaching machine that is configured to crimp the joint member with the sheet-like member sandwiched therebetween, a receiver that supports the synthetic resin rivet member with the protrusion facing upward, and a receiver above the receiver A first hopper for housing a fitting member made of synthetic resin in which a through hole for inserting a protrusion of the rivet member is formed in the center, and a rivet member A second hopper that feeds, a first chute that feeds down the fitting member fed from the first hopper, and a second shoe that feeds down the rivet member fed from the second hopper The upper and lower two-stage pressing plates that feed the fitting member fed down to the lower end of the first chute into the driving tool and the rivet member fed down to the lower end of the second chute into the receiving tool, respectively. A pusher capable of reciprocating in the front-rear direction having a portion, an elevating drive means for the driving tool, and a driving means for the pusher. An openable and closable upper chuck for holding a fitting member that is slidable in the vertical direction on the tool body, and a cylindrical shaft that is slidable in the vertical direction with respect to the driving tool body and biased downward by the biasing means. A guide punch, and a caulking punch disposed inside the guide punch and fixed to the driving tool body, wherein the receiving tool includes a receiving table on which a rivet member is placed; An openable and closable lower chuck for positioning the sheet-like member configured to descend synchronously with the lowering of the jig at a predetermined timing, and the sheet-like member is interposed between the receiving tool and the driving tool In this state, by lowering the driving tool, the fitting member is pushed down by the guide punch, and the protrusion of the rivet member is inserted into the sheet-like member and inserted into the through hole of the fitting member, and the protrusion tip is inserted by the caulking punch. The present invention relates to a snap fastener attaching machine in which the diameter of the rivet member and the fitting member are squeezed and fixed in a state where a sheet-like member is sandwiched between the rivet member and the fitting member.

この種のスナップファスナー取付け機は、特許文献1にも記載されているように、受け具と打込み具との間に、例えば、衣服における前身頃の端縁等のシート状部材を介在させた状態で、ペダルを踏み込むと、モータ出力により一回転クラッチを介して駆動される打込み具が下降し、リベット部材と嵌合用部材とをシート状部材を挟んだ状態にカシメ止めした後、打込み具が昇降ストロークの上端まで上昇復帰し、次のリベット部材及び嵌合用部材がプッシャーによって自動的に受け具及び打込み具に送り込まれるので、受け具及び打込み具にリベット部材及び嵌合用部材を手動で供給するいわゆる半自動機に比べると、スナップファスナー取付け作業を能率良く行える利点がある。   In this type of snap fastener attaching machine, as described in Patent Document 1, for example, a sheet-like member such as an edge of the front body of clothing is interposed between the receiving tool and the driving tool. When the pedal is depressed, the driving tool driven by the motor output through the one-rotation clutch is lowered, and the driving tool is moved up and down after the rivet member and the fitting member are clamped and held between the sheet-like members. Ascending and returning to the upper end of the stroke, the next rivet member and fitting member are automatically fed to the receiving tool and the driving tool by the pusher, so that the rivet member and the fitting member are manually supplied to the receiving tool and the driving tool. Compared to a semi-automatic machine, there is an advantage that the snap fastener can be attached efficiently.

ところで、一着の衣服であっても、それに取り付けるスナップファスナーが全て同じものであるとは限らず、例えば、衣服の色模様に合わせて、特定位置のスナップファスナーだけ、リベット部材の色を衣服と同色のものに変えることがある。また、一着の衣服においても、端部では何枚もの布地が重ねられて厚さが厚くなっているのが普通であり、このような厚肉箇所に取り付けるスナップファスナーだけ、突起の長いリベット部材を用いることがある。   By the way, even if it is a single garment, not all the snap fasteners attached to it are the same. For example, according to the color pattern of the garment, only the snap fastener at a specific position and the color of the rivet member are the same as the garment. May change to the same color. Also, even in a single garment, it is common for the end to have a number of pieces of fabric piled up to increase the thickness, and only the snap fastener attached to such a thick part has a long protrusion. May be used.

しかしながら、従来のスナップファスナー取付け機(自動機)では、打込み具が昇降ストロークの上端で停止したとき、前後方向に往復移動するプッシャーがその往復ストロークの前端まで前進してリベット部材及び嵌合用部材を受け具及び打込み具に送り込んだ状態にあるため、プッシャーの下段の押圧用板部が障害物になって、受け具上にあるリベット部材だけを色や突起長さの異なる別のリベット部材と交換することはできなかった。   However, in the conventional snap fastener attaching machine (automatic machine), when the driving tool stops at the upper end of the lifting / lowering stroke, the pusher that reciprocates back and forth moves forward to the front end of the reciprocating stroke to move the rivet member and the fitting member. Since it is in the state of being fed into the receiving tool and the driving tool, the pressing plate at the lower stage of the pusher becomes an obstacle, and only the rivet member on the receiving device is replaced with another rivet member having a different color and protrusion length. I couldn't.

そのため、従来では、色や突起長さの異なるリベット部材を用いる箇所だけ、スナップファスナー取付け作業を残しておき、適当な時点で、例えば、全ての衣服に対する同一スナップファスナーの取付け作業が完了した後、スナップファスナー取付け機(自動機)の第2ホッパーや第2シュート内に残っているリベット部材を全て取り出し、色や突起長さの異なる別のリベット部材と入れ換えて、スナップファスナー取付け作業を残しておいた箇所にスナップファスナーを取り付けるか、あるいは、スナップファスナー取付け機(自動機)とは別に、受け具及び打込み具にリベット部材及び嵌合用部材を手動で供給する半自動機を用意しておき、スナップファスナー取付け作業を残しておいた箇所に、半自動機でスナップファスナーを取り付けたりしており、このことが作業能率を低下させる要因となっていた。   Therefore, in the past, the snap fastener attaching work is left only in the place where the rivet member having a different color and protrusion length is used, and after the attaching work of the same snap fastener to all clothes is completed at an appropriate time, for example, Remove all rivet members remaining in the second hopper and second chute of the snap fastener attaching machine (automatic machine) and replace them with other rivet members of different colors and protrusion lengths, leaving the snap fastener attaching work. A snap fastener is attached to the place where the snap fastener is attached, or a semi-automatic machine that manually supplies the rivet member and the fitting member to the receiving tool and the driving tool separately from the snap fastener attaching machine (automatic machine). Install the snap fastener with a semi-automatic machine at the place where the installation work was left. And or, and this has been a factor of lowering the work efficiency.

The squeezing punch is configured to be openable and closable for positioning the sheet-shaped member configured to be synchronized with the cradle on which the rivet member is placed and the descent of the driving tool at a predetermined timing. A lower chuck, and the guide punch is fitted by lowering the driving tool in a state where a sheet-like member is interposed between the receiving tool and the driving tool. The member is pushed down, the protrusion of the rivet member is pierced into the sheet-like member and inserted into the through hole of the fitting member, the protrusion tip is struck by the caulking punch, and the diameter of the protrusion is increased, and the rivet member and the fitting member In a snap fastener attaching machine in which the sheet-like member is clamped, when the driving tool stops at the upper end of the lifting / lowering stroke, the pusher is a lower pressing plate portion and the rivet member is received by the pressing plate portion. Stops at a position retracted by a small distance from the front end of the reciprocating stroke sent to the gap between the pressing plate at the lower stage of the pusher and the rivet member in the holder so that the rivet member can be manually taken out and loaded. It is characterized in that it is formed.

請求項2に記載の発明は、請求項1に記載のスナップファスナー取付け機において、第2シュートの下端近傍部に、最下端に位置するリベット部材と下から2番目のリベット部材との間に突入した流出阻止状態と、前記リベット部材間から退出した流出許容状態とに切換え可能なストッパーを設けたことを特徴としている。   According to a second aspect of the present invention, in the snap fastener attaching machine according to the first aspect, in the vicinity of the lower end of the second chute, it rushes between the rivet member located at the lowermost end and the second rivet member from the bottom. A stopper is provided that can be switched between the outflow prevention state and the outflow permission state withdrawn from between the rivet members.

請求項1に記載の発明によれば、第1シュートの下端まで流下供給された嵌合用部材を打込み具に、第2シュートの下端まで流下供給されたリベット部材を受け具に、夫々、送り込む上下二段の押圧用板部を有する前後方向に往復移動可能なプッシャーを備えたスナップファスナー取付け機であるにも拘わらず、前記打込み具が昇降ストロークの上端で停止したとき、前記プッシャーが下段の押圧用板部でリベット部材を前記受け具に送り込んだ往復ストロークの前端から小距離後退した位置で停止し、プッシャーの下段の押圧用板部と受け具内のリベット部材との間に手動によるリベット部材の取出し及び装填が可能な寸法の隙間が形成されるように構成したので、例えば、特定位置のスナップファスナーだけ、異なる色のリベット部材を用いたり、突起の長いリベット部材を用いる場合、プッシャーの下段の押圧用板部が障害物にならず、受け具にあるリベット部材を指先やピンセットで取り出し、別のリベット部材を受け具に手動で装填することが可能である。According to the first aspect of the present invention, the fitting member fed down to the lower end of the first chute is fed into the driving tool, and the rivet member fed down to the lower end of the second chute is fed into the receiving tool. In spite of being a snap fastener attaching machine having a pusher capable of reciprocating in the front-rear direction having a two-stage pressing plate portion, when the driving tool stops at the upper end of the lifting stroke, the pusher The rivet member is stopped manually at a position retracted by a small distance from the front end of the reciprocating stroke in which the rivet member is sent to the receiver by the plate portion, and the rivet member is manually placed between the lower pressing plate portion and the rivet member in the receiver. removal and because the loading is configured as a gap size that can be formed of, for example, only a snap fastener for a particular position, the rivet member of a different color If a rivet member with a long protrusion is used, the pressing plate at the bottom of the pusher does not become an obstacle, and the rivet member on the holder is removed with a fingertip or tweezers, and another rivet member is manually loaded on the holder. Is possible.

従って、第1,2ホッパー、第1,2シュート、上下二段の押圧用板部を有するプッシャー等を備えたスナップファスナー取付け機(自動機)であるにも拘わらず、必要に応じて、色や突起長さの異なるリベット部材を手動で供給する半自動機としても使用でき、衣服等に対するスナップファスナー取付け作業の能率を著しく向上し得る効果がある。   Therefore, although it is a snap fastener attaching machine (automatic machine) equipped with first and second hoppers, first and second chutes, a pusher having two upper and lower pressing plates, etc. It can also be used as a semi-automatic machine for manually supplying rivet members having different projection lengths, and has the effect of significantly improving the efficiency of snap fastener attachment work on clothes and the like.

殊に、請求項2に記載の発明によれば、第2シュートの下端近傍部に、最下端に位置するリベット部材と下から2番目のリベット部材との間に突入した流出阻止状態と、前記リベット部材間から退出した流出許容状態とに切換え可能なストッパーを設けたので、異なる色のリベット部材や突起長さの異なるリベット部材に変更する一つ前のスナップファスナーを取り付ける直前に、流出許容状態にあったストッパーを流出阻止状態に切り換え、この状態で、スナップファスナーの取付け作業を行うと、第2シュートからのリベット部材の流出が無いので、プッシャーの上段の押圧用板部は嵌合用部材を打込み具に送り込むが、下段の押圧用板部は受け具に空送りすることになり、受け具にリベット部材が支持されていない状態となる。   In particular, according to the invention described in claim 2, the outflow prevention state that has entered between the rivet member located at the lowermost end and the second rivet member from the bottom in the vicinity of the lower end of the second chute, Since a stopper that can be switched between the rivet member and the rivet member that has been withdrawn from between the rivet members is provided, the spillable state immediately before installing the previous snap fastener to be changed to a rivet member of a different color or a different rivet member In this state, when the snap fastener is attached, there is no outflow of the rivet member from the second chute. Although it is fed into the driving tool, the lower pressing plate portion is fed to the receiving tool, and the rivet member is not supported by the receiving tool.

従って、受け具から不要なリベット部材を取り出す手間が要らず、色や突起長さの異なるリベット部材を手動で受け具に容易かつ敏速に装填することができ、作業能率を一層向上することができる。   Therefore, there is no need to take out an unnecessary rivet member from the receiver, and rivet members of different colors and protrusion lengths can be manually and quickly loaded on the receiver, and the work efficiency can be further improved. .

And a circular hole located at the end of the guide groove (directly above the cradle 32), and the inner diameter of the circular hole is larger than the diameter of the head of the rivet member A. It has a slightly larger diameter. Reference numeral 35 denotes a guide plate for guiding the vertical movement of the lower chuck 33, which is positioned on the lower front surface of the block-shaped frame 4 by two pins 36 and fixed by bolts 37.

下部チャック33における左右一対の部材の下端部は、ブロック状フレーム4に横軸38で枢支された揺動アーム39の前端に挿抜自在なピン40で枢着されており、揺動アーム39が横軸38まわりに、図2〜図4で時計回り方向へ揺動することによって、下部チャック33がスプリング34に抗して左右に開きつつ下降するように構成されている。   The lower ends of the pair of left and right members of the lower chuck 33 are pivotally attached to the front end of a swing arm 39 pivotally supported by the block-shaped frame 4 by a horizontal shaft 38 with a pin 40 that can be inserted and removed. By swinging in the clockwise direction in FIGS. 2 to 4 about the horizontal axis 38, the lower chuck 33 is configured to descend while opening left and right against the spring 34.

下部チャック33の下端部に枢支連結された揺動アーム39の後端には、孔のあいたプレート41が固着されている。プレート41の孔には、ロッド42が挿入され、ロッド42の下端側にはタイミング調整用のナット43が螺着されている。ロッド42の上端は、上部フレーム5に支点軸44を介して枢支された揺動リンク45の後端にピン46で連結され、揺動リンク45の前端と、支点軸47まわりで揺動する揺動リンク48の中間部とは、長さ調節可能なリンク49により枢支連結されている。揺動リンク48は、後述する打込み具9の昇降駆動手段の一部を構成するものであり、打込み具9の昇降に伴い支点軸47まわりで上下に揺動するように構成されている。   A plate 41 with a hole is fixed to the rear end of the swing arm 39 pivotally connected to the lower end of the lower chuck 33. A rod 42 is inserted into the hole of the plate 41, and a timing adjusting nut 43 is screwed to the lower end side of the rod 42. The upper end of the rod 42 is connected to the rear end of a swing link 45 pivotally supported by the upper frame 5 via a fulcrum shaft 44, and swings about the fulcrum shaft 47 around the front end of the swing link 45. The intermediate portion of the swing link 48 is pivotally connected by a link 49 whose length can be adjusted. The swing link 48 constitutes a part of a lifting / lowering driving means of the driving tool 9 described later, and is configured to swing up and down around the fulcrum shaft 47 as the driving tool 9 moves up and down.

そして、打込み具9の下降に伴う揺動リンク48の下方への揺動によって、前記揺動リンク45が、図2〜図4で時計回り方向に揺動して、ロッド42を引き上げると、所定のタイムラグをもってナット43がプレート41の下面に当接し、ナット43がプレート41を引き上げるので、揺動アーム39が時計回り方向に揺動して、下部チャック33を下降させるように構成されている。50は、揺動アーム39を反時計回り方向に付勢して、下部チャック33を上昇姿勢に保持するコイルスプリングであり、ロッド42に套嵌した状態に設けられている。尚、揺動リンク45の支点軸44は、揺動リンク45と一体に回転するように上部フレーム5に軸支されており、当該支点軸44の両端部に、第1,第2ホッパー12a,12bを駆動する前記揺動アーム17a,17bが固定されている。   When the swing link 45 swings in the clockwise direction in FIGS. 2 to 4 due to the downward swing of the swing link 48 as the driving tool 9 descends, the rod 42 is lifted up. The nut 43 comes into contact with the lower surface of the plate 41 with the time lag and the nut 43 pulls up the plate 41, so that the swing arm 39 swings in the clockwise direction to lower the lower chuck 33. Reference numeral 50 denotes a coil spring that urges the swing arm 39 counterclockwise to hold the lower chuck 33 in an ascending posture, and is provided in a state of being fitted onto the rod 42. The fulcrum shaft 44 of the swing link 45 is pivotally supported by the upper frame 5 so as to rotate integrally with the swing link 45, and the first and second hoppers 12a, 12a, The swing arms 17a and 17b for driving 12b are fixed.

上記の構成によれば、図5、図6、図11に示すように、前記受け具8と前記打込み具9との間に衣服の端縁などのシート状部材Cを介在させた状態で、打込み具9を下降させることにより、図12の(イ)に示すように、上部チャック23が嵌合用部材Bを保持した状態で下降し、上部チャック23が下部チャック33で支持されたシート状部材Cに当接した後も、打込み具本体22が更に下降を続けることにより、図12の(ロ)に示すように、前記ガイドパンチ24が嵌合部材Bを押し下げるので、リベット部材Aの突起aシート状部材Cを貫通して、嵌合部材Bの貫通孔bに挿入される。   According to said structure, as shown in FIG.5, FIG.6, FIG.11, in the state which interposed the sheet-like member C, such as the edge of clothes, between the said receiving tool 8 and the said driving tool 9, By lowering the driving tool 9, as shown in FIG. 12A, the upper chuck 23 is lowered while holding the fitting member B, and the upper chuck 23 is supported by the lower chuck 33. Even after coming into contact with C, the guide punch 24 pushes down the fitting member B as shown in FIG. The sheet-like member C is inserted and inserted into the through hole b of the fitting member B.

この状態で、ガイドパンチ24及びカシメパンチ25が更に下降を続け、図13に示すように、ガイドパンチ24の下降が受け台32で阻止された後も、カシメパンチ25がガイドパンチ24に対して下降することにより、カシメパンチ25で突起a先端部を打撃して拡径変形させ、前記リベット部材Aと前記嵌合用部材Bとをシート状部材Cを挟んだ状態にカシメ止めすることになる。   In this state, the guide punch 24 and the caulking punch 25 continue to descend further, and the caulking punch 25 descends with respect to the guide punch 24 even after the lowering of the guide punch 24 is blocked by the cradle 32 as shown in FIG. Thus, the tip end portion of the protrusion a is struck by the caulking punch 25 to be expanded in diameter, and the rivet member A and the fitting member B are caulked and stopped with the sheet-like member C interposed therebetween.

尚、図11〜図13においては、嵌合用部材Bとして、雄型の嵌合用部材Bを図示したが、ガイドパンチ25及びカシメパンチ26を雌スナップ用のものと交換することにより、雌型の嵌合用部材Bとリベット部材Aのカシメ止めを行うことができる。即ち、スナップファスナーは、図14に示すように、雄スナップDを形成するリベット部材A及び雄型の嵌合用部材Bと、雌スナップEを形成するリベット部材A及び雌型の嵌合用部材Bの四部材で作製されるものであり、ガイドパンチ25及びカシメパンチ26の交換によって、雄スナップD、雌スナップEの何れでも作製できるのである。   11 to 13, the male fitting member B is shown as the fitting member B. However, by replacing the guide punch 25 and the caulking punch 26 with those for female snapping, a female fitting can be obtained. The joint member B and the rivet member A can be caulked. That is, the snap fastener includes a rivet member A and a male fitting member B that form a male snap D, and a rivet member A and a female fitting member B that form a female snap E, as shown in FIG. It is made of four members, and either the male snap D or the female snap E can be produced by exchanging the guide punch 25 and the caulking punch 26.

打込み具9の昇降駆動手段は、前記カム軸6と、カム軸6に設けた第1のカム51と、第1のカム51に追従する第1のカムフォロワー52と、第1のカムフォロワー52の動作を打込み具9の昇降動作に変換する連動機構53とで構成され、カム面のうち所定の角度範囲(図示の例では、略150度)αを円形状(半径が一定した円弧状)に形成することにより、カム軸6が矢印方向Xに一回転する間に、打込み具9がリベット部材Aの突起先端部を拡径変形させた状態で一定時間静止するように構成してある。   The raising / lowering drive means of the driving tool 9 includes the cam shaft 6, a first cam 51 provided on the cam shaft 6, a first cam follower 52 that follows the first cam 51, and a first cam follower 52. And an interlocking mechanism 53 that converts the movement of the driving tool 9 into the raising / lowering movement of the driving tool 9, and a predetermined angular range (approximately 150 degrees in the illustrated example) of the cam surface is a circular shape (an arc having a constant radius). Thus, while the camshaft 6 makes one rotation in the arrow direction X, the driving tool 9 is configured to stand still for a certain period of time while the tip end of the protrusion of the rivet member A is expanded and deformed.

そして、円形状のカム面部分(所定の角度範囲α)に先行する狭い角度範囲(急角度で偏芯するカム面部分)β、つまり、円形状に形成された所定の角度範囲(打込み具を一定時間静止させるためのカム面部分)αを除く部分の更に1/2以下のカム面部分が打込み具9の下降(リベット部材Aのシート状部材Cへの貫通からリベット部材Aの突起a先端部の打撃まで)を司るように構成してある。   Then, a narrow angle range (cam surface portion eccentric at a steep angle) β preceding the circular cam surface portion (predetermined angle range α), that is, a predetermined angle range (driving tool) formed in a circular shape. The cam surface portion that is less than half of the portion excluding α) that is stationary for a certain period of time is the descent of the driving tool 9 (from the penetration of the rivet member A into the sheet-like member C to the tip of the protrusion a of the rivet member A) It is configured to administer up to the hit of the department.

図示の連動機構53は、打込み具本体22の上端に枢支連結されたリンク54と、当該リンク54にピン55と長孔56の範囲で伸縮自在に連結され且つ圧縮スプリング57によって伸長方向に付勢されたリンク58と、上部フレーム5に支点軸47まわりで揺動自在に枢支された揺動リンク48と、当該揺動リンク48の先端近傍部に上端を枢着し、下端に第1のカムフォロワー52を軸支したロッド59と、復帰用のバネ60とで構成されている。ロッド59の下端近傍部にはカム軸6を挿通する長孔59aが形成されている。   The interlocking mechanism 53 shown in the figure is a link 54 pivotally connected to the upper end of the driving tool main body 22, and is connected to the link 54 in a range of a pin 55 and a long hole 56 so as to be extendable and contracted by a compression spring 57 in the extending direction. The oscillating link 58, the oscillating link 48 pivotally supported on the upper frame 5 around the fulcrum shaft 47, the upper end pivotally attached to the vicinity of the tip of the oscillating link 48, and the first end at the lower end. The cam follower 52 is supported by a rod 59 and a return spring 60. A long hole 59 a through which the cam shaft 6 is inserted is formed in the vicinity of the lower end of the rod 59.

前記プッシャー21は、図3、図6に示すように、下段の押圧用板部21bが第2シュート13bを流下するリベット部材Aよりも後退した後端位置と、図4、図7に示すように、上段の押圧用板部13aが第1シュート13aを流下した嵌合用部材Bを打込み具9に上チャック23で保持される位置まで送り込み、且つ、下段の押圧用板部13bが第2シュート13bを流下したリベット部材Bを受け具8に送り込んだ前進位置との間をストローク長として往復移動するが、図2、図5に示すように、前記打込み具9が昇降ストロークの上端で停止したとき、前記プッシャー21が、往復ストロークの前端まで前進して、嵌合用部材Bを前記打込み具9に、リベット部材Bを前記受け具8に、夫々、送り込んだ後、往復ストロークの前端から小距離後退した位置で停止することにより、プッシャー21の上段の押圧用板部13aと打込み具9に送り込まれた嵌合部材Bとの間に隙間Sが形成され、且つ、プッシャー21の下段の押圧用板部13bと受け具8に送り込まれたリベット部材Bとの間に隙間Sが形成されるように構成してある。 As shown in FIGS. 3 and 6, the pusher 21 has a rear end position where the lower pressing plate portion 21b is retracted from the rivet member A flowing down the second chute 13b, and as shown in FIGS. Then, the upper pressing plate portion 13a feeds the fitting member B, which has flowed down the first chute 13a, to the position held by the upper chuck 23 to the driving tool 9, and the lower pressing plate portion 13b is moved to the second chute. The rivet member B that has flowed down 13b reciprocates as a stroke length with respect to the advance position sent to the receiving tool 8, but the driving tool 9 stops at the upper end of the lifting stroke as shown in FIGS. When the pusher 21 moves forward to the front end of the reciprocating stroke, the fitting member B is fed into the driving tool 9 and the rivet member B is fed into the receiving tool 8, respectively. By stopping at a position short distance backward, a gap S 1 is formed between the fitting member B fed into the implanted device 9 and the pressing plate part 13a of the upper pusher 21, and, the lower pusher 21 A gap S <b> 2 is formed between the pressing plate portion 13 b and the rivet member B fed into the receiving member 8.

換言すれば、前記プッシャー21は往復ストロークの前端から小距離後退した位置を基点とし(図5参照)、打込み具9の一回の昇降動作に合わせて、打込み具9の下降時には、基点から往復トロークの後端まで後退し(図6参照)、打込み具9の上昇時には、リベット部材A及び嵌合用部材Bを受け具8及び打込み具9に送り込む往復トロークの前端まで前進(図7参照)した後、再び基点に戻って(図5参照)停止するように構成されている。   In other words, the pusher 21 is based on a position retracted by a small distance from the front end of the reciprocating stroke (see FIG. 5), and reciprocates from the base point when the driving tool 9 is lowered in accordance with a single lifting operation of the driving tool 9. Retracted to the rear end of the troke (see FIG. 6), and when the driving tool 9 was raised, the rivet member A and the fitting member B were moved forward to the front end of the reciprocating troke to be fed into the receiving tool 8 and the driving tool 9 (see FIG. 7). After that, it is configured to return to the base point again (see FIG. 5) and stop.

プッシャー21の駆動手段は、前記カム軸6と、カム軸6に設けた第2のカム61と、第2のカム61に追従する第2のカムフォロワー62と、第2のカムフォロワー62の動作をプッシャー21の前後方向往復動作に変換する連動機構63とで構成してある。   The drive means of the pusher 21 includes the cam shaft 6, a second cam 61 provided on the cam shaft 6, a second cam follower 62 that follows the second cam 61, and the operations of the second cam follower 62. Is constructed with an interlocking mechanism 63 that converts the pusher 21 into a reciprocating motion in the front-rear direction.

図示の連動機構63は、ブロック状フレーム4により前後方向スライド自在にガイドされ且つ先端にプッシャー21を着脱交換可能な状態に取り付けた2本のロッド64と、両ロッド64を前方へスライド付勢するバネ65と、前記ロッド64の後端部に横架したローラ66と、支柱3に横軸67を介して揺動自在に枢支され、下端部に第2のカムフォロワー62を軸支し、上端部を前記ローラ66の前部に当接させた揺動アーム68と、第2のカムフォロワー62が第2のカム61に圧接する方向に揺動アーム68を横軸67まわりに付勢するバネ69とで構成されている。   The illustrated interlocking mechanism 63 is guided by the block-like frame 4 so as to be slidable in the front-rear direction, and has two rods 64 attached to the tip in a state where the pusher 21 can be attached and detached, and slidably bias both rods 64 forward. A spring 65, a roller 66 horizontally mounted on the rear end portion of the rod 64, and a pivot 3 that is pivotably supported by the support column 3 via a horizontal shaft 67; a second cam follower 62 is pivotally supported at the lower end portion; The swing arm 68 with its upper end abutted against the front portion of the roller 66 and the swing arm 68 are urged around the horizontal axis 67 in the direction in which the second cam follower 62 is in pressure contact with the second cam 61. A spring 69 is included.

即ち、プッシャー21は、リベット部材A及び嵌合用部材Bを受け具8及び打込み具9に送り込む前方への移動(前進動作)をバネ65の力によって行い、後進動作を第2のカム61によって揺動駆動される揺動アーム68によって行うように構成されている。揺動アーム68の上端部を前記ローラ66の軸に直結せず、単に、ローラ66の前部に当接させてあるのは、受け具8や打込み具9に異物が詰まる等の不測の事態が生じた際、プッシャー21が機械力によって無理に前進して、受け具8や打込み具9等を破損しないように配慮したものである。   In other words, the pusher 21 performs forward movement (advance operation) to feed the rivet member A and the fitting member B to the receiving device 8 and the driving device 9 by the force of the spring 65, and the backward operation is shaken by the second cam 61. It is configured to be performed by a swing arm 68 that is dynamically driven. If the upper end of the swing arm 68 is not directly connected to the shaft of the roller 66 but is simply brought into contact with the front of the roller 66, an unexpected situation such as a clogging of the receiving tool 8 or the driving tool 9 may occur. In this case, it is considered that the pusher 21 does not forcibly move forward due to mechanical force and the receiving tool 8, the driving tool 9 and the like are not damaged.

尚、70はシート状部材Cを載置する作業台であり、本体フレーム1に着脱自在に装着されている。作業台70には、シート状部材Cの後端縁を突き当てることが可能な位置決め用立ち上がり片71が蝶ボルトとナットにより前後に位置調節可能な状態に装着されている。72は前記打込み具9の後方に配設されたマーキングプロジェクターであり、打込み具9が昇降ストロークの上端にあるとき、前記隙間Sを通して、シート状部材Cの所定位置(シート状部材Cにおけるリベット部材Aの突起aの真上位置)に十字状のスポットライトMを照射するように構成してある。マーキングプロジェクター72は、ブロック状フレーム4に左右方向の支点軸73を介して当該支点軸73まわりに前後方向揺動自在に枢支され、且つ、バネ(図示に例では板バネである。)74により一方向に揺動付勢されている。 Reference numeral 70 denotes a work table on which the sheet-like member C is placed, and is detachably attached to the main body frame 1. On the work table 70, a positioning rising piece 71 capable of abutting the rear end edge of the sheet-like member C is mounted in a state in which the position can be adjusted back and forth by a butterfly bolt and a nut. Reference numeral 72 denotes a marking projector disposed behind the driving tool 9. When the driving tool 9 is at the upper end of the lifting stroke, a predetermined position of the sheet-like member C (the rivet in the sheet-like member C is passed through the gap S 1. A cross-shaped spotlight M is irradiated onto the protrusion A of the member A). The marking projector 72 is pivotally supported on the block frame 4 via a fulcrum shaft 73 in the left-right direction so as to be swingable in the front-rear direction around the fulcrum shaft 73, and is a spring (in the illustrated example, a leaf spring) 74. Is oscillated and biased in one direction.

そして、図15、図16に示すように、先端がテーパー状に形成されたネジ軸からなる調節具75を適当な工具76で回転操作することにより、マーキングプロジェクター72を前記バネ74に抗して支点軸73まわりに揺動して、光軸を前後に調整するように構成されている。図16に示すPは、予め、シート状部材Cの表面に記されたスナップファスナー取付け位置を示すマークである。   Then, as shown in FIGS. 15 and 16, the marking projector 72 is resisted against the spring 74 by rotating the adjusting tool 75 made of a screw shaft having a tapered tip with an appropriate tool 76. It is configured to swing around the fulcrum shaft 73 and adjust the optical axis back and forth. P shown in FIG. 16 is a mark indicating a snap fastener attachment position written on the surface of the sheet-like member C in advance.

第2シュート13bの下端近傍部には、図17〜図19に示すように、最下端に位置するリベット部材Aと下から2番目のリベット部材Aとの間に突入した流出阻止状態(図19参照)と、前記リベット部材A,A間から退出した流出許容状態(図18参照)とに切換え可能なストッパー76が支点となる縦方向のボルト77まわりで回動自在に枢着されている。   In the vicinity of the lower end of the second chute 13b, as shown in FIGS. 17 to 19, the outflow prevention state that has entered between the rivet member A located at the lowermost end and the second rivet member A from the bottom (FIG. 19). And a stopper 76 that can be switched between the rivet members A, A and the allowed flow-out state (see FIG. 18) pivoted around a vertical bolt 77 serving as a fulcrum.

78はストッパー76を押圧して摩擦力によって上記二状態に固定するコイルスプリング、79はバネ圧調整用ナットである。ストッパー76には、指先を係止させるための操作用開口部76aが形成されている。80aは第1シュート13aの先端の蓋部材、80bは第2シュート13bの先端の蓋部材であり、これらの蓋部材80a,80bを取り外して、第1,第2シュート13a,13bの先端を開放することにより、シュート内部の嵌合部材Bやリベット部材Aを抜き取ることができる。81は蓋部材80aの固定用ボルト、82は蓋部材80bの固定用板バネ、83は位置決め用突起である。   Reference numeral 78 denotes a coil spring that presses the stopper 76 and fixes it in the above two states by frictional force, and 79 is a spring pressure adjusting nut. The stopper 76 is formed with an operation opening 76a for locking the fingertip. 80a is a lid member at the tip of the first chute 13a, and 80b is a lid member at the tip of the second chute 13b. These lid members 80a and 80b are removed to open the tips of the first and second chutes 13a and 13b. By doing so, the fitting member B and the rivet member A inside the chute can be extracted. Reference numeral 81 denotes a fixing bolt for the lid member 80a, 82 denotes a fixing plate spring for the lid member 80b, and 83 denotes a positioning projection.

上記の構成によれば、第1のカム51に形成されるカム面のうち所定の角度範囲αを円形状に形成することにより、カム軸6が一回転する間に打込み具9がリベット部材Aの突起a先端部を拡径変形させた状態で一定時間静止するように構成したので、カム軸6が一回転する間に、突起先端の拡径変形部cが塑性変形した状態に安定するまでの時間を確保でき、合成樹脂の弾性によって拡径変形部cが打込み具9による加圧方向と逆方向に復元することを確実に防止できる。   According to the above configuration, the driving tool 9 can be moved to the rivet member A during one rotation of the cam shaft 6 by forming a predetermined angular range α of the cam surface formed on the first cam 51 in a circular shape. Since the tip end portion of the protrusion a is stationary for a predetermined time in a state where the diameter of the protrusion a is deformed, until the cam shaft 6 makes one rotation, the diameter expanding deformation portion c at the tip of the protrusion is stabilized in a plastically deformed state. It is possible to reliably prevent the diameter-enlarged deformation portion c from being restored in the direction opposite to the pressing direction by the driving tool 9 due to the elasticity of the synthetic resin.

殊に、カム軸6が一回転する時間のうち、打込み具9の静止時間を除く僅かな時間が打込み具9の下降と上昇の双方に費やされることになるから、つまり、カム軸6上の第1のカム51に設けられた360度のカム面のうち、円形状に形成された所定の角度範囲(打込み具9を一定時間静止させるためのカム面部分)αを除く部分の更に1/2以下のカム面部分(所定の角度範囲αに先行する狭い角度範囲β)が打込み具9の下降を司ることになるから、嵌合部材Bの押下げによるリベット部材Aの突起aのシート状部材Cへの貫通を高速で行うことができる。   In particular, of the time for which the camshaft 6 rotates once, a small amount of time excluding the resting time of the driving tool 9 is spent for both lowering and raising of the driving tool 9, that is, on the camshaft 6. Of the 360-degree cam surface provided on the first cam 51, 1 / of a portion excluding a predetermined angular range (cam surface portion for allowing the driving tool 9 to stand still for a certain period) α formed in a circular shape. Since the cam surface portion of 2 or less (the narrow angle range β preceding the predetermined angle range α) governs the lowering of the driving tool 9, the sheet shape of the protrusion a of the rivet member A by pressing down of the fitting member B The penetration to the member C can be performed at high speed.

従って、リベット部材Aの材料樹脂が、ポリアセタールである場合は勿論、たとえ、ポリエチレンやポリエステル等であっても、シート状部材Cに対するリベット部材Aの貫通を確実に行わせ、それでいて、カシメ止め(突起先端部の打撃による拡径変形)を材料樹脂の弾性による復元のない状態に行えることになる。   Therefore, when the material resin of the rivet member A is polyacetal, even if it is polyethylene, polyester, or the like, the rivet member A can be surely penetrated into the sheet-like member C, and the rivet member (projection) The diameter expansion deformation due to the impact of the tip portion) can be performed without the restoration due to the elasticity of the material resin.

また、上記の構成によれば、第1シュート13aの下端まで流下供給された嵌合用部材Bを打込み具9に、第2シュート13bの下端まで流下供給されたリベット部材Aを受け具8に、夫々、送り込む上下二段の押圧用板部21a,21bを有する前後方向に往復移動可能なプッシャー21を備えたスナップファスナー取付け機であるにも拘わらず、前記打込み具9が昇降ストロークの上端で停止したとき、前記プッシャー21が、往復ストロークの前端まで前進して、嵌合用部材Bを前記打込み具9に、リベット部材Aを前記受け具8に、夫々、送り込んだ後、往復ストロークの前端から小距離後退した位置で停止することにより、プッシャー21の上段の押圧用板部21aと打込み具9に送り込まれた嵌合部材Bとの間に隙間Sが形成されるように構成したので、打込み具9の後方に設けたマーキングプロジェクター72から前記隙間Sを通してシート状部材Cの所定位置にスポットライトMを照射すること(換言すれば、打込み具9の後方上部から手前側に向けてスポットライトMを照射すること)ができる。 In addition, according to the above configuration, the fitting member B supplied to the lower end of the first chute 13a is applied to the driving tool 9, and the rivet member A supplied to the lower end of the second chute 13b is applied to the receiving tool 8. The driving tool 9 stops at the upper end of the up / down stroke even though it is a snap fastener attaching machine having a pusher 21 which can be reciprocated in the front-rear direction having two upper and lower pressing plate portions 21a, 21b to be fed. Then, the pusher 21 is advanced to the front end of the reciprocating stroke, and after the fitting member B is fed into the driving tool 9 and the rivet member A into the receiving tool 8, respectively, the pusher 21 is gradually moved from the front end of the reciprocating stroke. By stopping at a position retracted by a distance, a gap S 1 is formed between the upper pressing plate portion 21 a of the pusher 21 and the fitting member B fed into the driving tool 9. Since it is configured to be, if possible (i.e. from the marking projector 72 provided behind the driving device 9 irradiates spotlight M at a predetermined position of the sheet-like member C through the gap S 1, behind the driving device 9 (Spotlight M can be irradiated from the top toward the front side).

従って、シート状部C材の厚さが変わっても、シート状部材Cの表面に当たるスポットライトMの位置が横方向にずれることがなく、煩わしい光軸調整を行わなくても、スナップファスナーの取付け間隔Lが狂う虞がない。   Accordingly, even if the thickness of the sheet-like portion C material is changed, the position of the spotlight M hitting the surface of the sheet-like member C is not shifted laterally, and the snap fastener can be attached without performing troublesome optical axis adjustment. There is no risk of the interval L going wrong.

尚、打込み具9の後方上部から手前側に向けてスポットライトMを照射する場合、シート状部材Cの厚さが変わると、シート状部材Cの表面に当たるスポットライトMの位置が前後方向にずれるが、この方向でのズレは、スナップファスナーの取付け間隔Lに大きな影響を及ぼさないので、実用上、さほど支障はないが、図示のように、作業台70を取り付けてスナップファスナー取付け作業を行えば、シート状部材Cの端縁を作業台70の立ち上がり片71に当て付けて、シート状部材Cの端縁を前後に位置決めした状態でスナップファスナーの取付けを行うことができるので、前後方向におけるスナップファスナー取付け位置のズレを無くすことができる。   In addition, when irradiating the spotlight M from the rear upper part of the driving tool 9 toward the front side, when the thickness of the sheet-like member C changes, the position of the spotlight M hitting the surface of the sheet-like member C shifts in the front-rear direction. However, the displacement in this direction does not greatly affect the snap fastener attachment interval L, so there is no practical problem. However, as shown in FIG. The snap fastener can be attached with the edge of the sheet-like member C applied to the rising piece 71 of the work table 70 and the edge of the sheet-like member C positioned in the front-rear direction. Misalignment of the fastener mounting position can be eliminated.

また、上記の構成によれば、調節具75を適当な工具76で回転操作することにより、マーキングプロジェクター72を前記バネ74に抗して支点軸73まわりに揺動し、シート状部材Cの表面に当たるスポットライトMの位置を前後方向に調整できるから、作業台70を取り付けずにスナップファスナー取付け作業を行う場合でも、前後方向におけるスナップファスナー取付け位置のズレを無くすことができる。   Further, according to the above configuration, the marking projector 72 is swung around the fulcrum shaft 73 against the spring 74 by rotating the adjusting tool 75 with an appropriate tool 76, and the surface of the sheet-like member C Since the position of the spotlight M hitting can be adjusted in the front-rear direction, even when the snap fastener attaching operation is performed without attaching the work table 70, the snap fastener attaching position in the front-rear direction can be eliminated.

しかも、上記の構成によれば、第1シュート13aの下端まで流下供給された嵌合用部材Bを打込み具9に、第2シュート13bの下端まで流下供給されたリベット部材Aを受け具8に、夫々、送り込む上下二段の押圧用板部21a,21bを有する前後方向に往復移動可能なプッシャー21を備えたスナップファスナー取付け機(自動機)であるにも拘わらず、前記打込み具9が昇降ストロークの上端で停止したとき、前記プッシャー21が、往復ストロークの前端まで前進して、嵌合用部材Bを前記打込み具9に、リベット部材Aを前記受け具8に、夫々、送り込んだ後、往復ストロークの前端から小距離後退した位置で停止することにより、プッシャー21の下段の押圧用板部21bと受け具8に送り込まれたリベット部材Bとの間に隙間Sが形成されるように構成したので、例えば、特定位置のスナップファスナーだけ、異なる色のリベット部材Aを用いたり、突起aの長いリベット部材Aを用いる場合、プッシャー21の下段の押圧用板部21bが障害物にならず、図20、図21に示すように、受け具8にあるリベット部材Aを指先やピンセット84で取り出し、異なる色のリベット部材Aや突起aの長いリベット部材Aを受け具8に手動で装填することが可能である。 Moreover, according to the above configuration, the fitting member B supplied to the lower end of the first chute 13a is supplied to the driving tool 9 and the rivet member A supplied to the lower end of the second chute 13b is supplied to the receiving tool 8. Despite being a snap fastener attaching machine (automatic machine) having a pusher 21 which can be reciprocated in the front-rear direction having two upper and lower pressing plate portions 21a, 21b to be fed, the driving tool 9 is moved up and down. When the pusher 21 moves forward to the front end of the reciprocating stroke, the fitting member B is fed into the driving tool 9 and the rivet member A is fed into the receiving tool 8, respectively. By stopping at a position retracted by a small distance from the front end of the pusher 21, the lower pressing plate 21 b between the pusher 21 and the rivet member B fed into the receiver 8 Since during configured as S 2 are formed, for example, only a snap fastener for a particular location, or using a rivet member A of different colors, when using a long rivet member A projections a, a pressing of the lower pusher 21 The plate portion 21b does not become an obstacle, and as shown in FIGS. 20 and 21, the rivet member A in the receiving device 8 is taken out with a fingertip or tweezers 84, and the rivet member A of a different color or the rivet member A having a long projection a is used. It is possible to manually load the receptacle 8.

従って、第1,2ホッパー12a,12b、第1,2シュート13a,13b、上下二段の押圧用板部21a,21bを有するプッシャー21等を備えたスナップファスナー取付け機(自動機)であるにも拘わらず、必要に応じて、色や突起長さH,hの異なるリベット部材Aを手動で供給する半自動機としても使用でき、衣服等に対するスナップファスナー取付け作業の能率を著しく向上し得る効果がある。   Accordingly, the snap fastener attaching machine (automatic machine) including the first and second hoppers 12a and 12b, the first and second chutes 13a and 13b, the pusher 21 having the upper and lower pressing plate portions 21a and 21b, and the like. Nevertheless, if necessary, it can also be used as a semi-automatic machine that manually supplies rivet members A of different colors and protrusion lengths H and h, and has the effect of significantly improving the efficiency of snap fastener attachment work on clothes etc. is there.

殊に、第2シュート13bの下端近傍部に、最下端に位置するリベット部材Aと下から2番目のリベット部材Aとの間に突入した流出阻止状態と、前記リベット部材A,A間から退出した流出許容状態とに切換え可能なストッパー76を設けたので、異なる色のリベット部材Aや突起a長さの異なるリベット部材Aに変更する一つ前のスナップファスナーを取り付ける直前に、流出許容状態にあったストッパー76を流出阻止状態に切り換え、この状態で、スナップファスナーの取付け作業を行うと、第2シュート13bからのリベット部材Aの流出が無いので、プッシャー21の上段の押圧用板部21aは嵌合用部材Bを打込み具9に送り込むが、下段の押圧用板部21bは受け具8に空送りすることになり、図20、図21に示すように、受け具8にリベット部材Aが支持されていない状態となる。   In particular, in the vicinity of the lower end of the second chute 13b, an outflow prevention state that has entered between the rivet member A located at the lowermost end and the second rivet member A from the bottom, and exit from between the rivet members A and A. Since the stopper 76 that can be switched to the allowed spilled state is provided, the spillable state is set immediately before attaching the previous snap fastener to be changed to the rivet member A having a different color or the rivet member A having a different projection a length. When the stopper 76 is switched to the outflow prevention state and the snap fastener is attached in this state, the rivet member A does not flow out from the second chute 13b. The fitting member B is fed into the driving tool 9, but the lower pressing plate portion 21b is fed to the receiving tool 8 as shown in FIGS. The receptacle 8 in a state where the rivet member A is not supported.

従って、受け具8から不要なリベット部材を取り出す手間が要らず、色や突起長さH,hの異なるリベット部材Aを手動で受け具8に容易かつ敏速に装填することができ、作業能率を一層向上することができる。   Accordingly, it is not necessary to take out an unnecessary rivet member from the receiver 8, and the rivet member A having a different color or protrusion length H or h can be manually and quickly loaded on the receiver 8. This can be further improved.
