本考案は、連結ネジの案内通路を備えたガイド部材を付設したネジ締め機を下 向きにした場合等において、連結ネジがガイド部材からずり落ちるのを防止する ずり落ち防止機構に関する。 The present invention relates to a slip-off prevention mechanism for preventing a connecting screw from slipping down from a guide member when a screw tightening machine provided with a guide member having a guide passage for the connecting screw is directed downward.
【０００２】[0002]
合成樹脂製の連結帯に複数のネジを一定の間隔に連結した連結ネジを使用する ネジ締め機は、連結帯の剛性が小さいので、容易に撓みやすい。そこで、ネジ締 め機本体に連結ネジを収容するガイド部材を付設し、ガイド部材の案内通路から ネジ締め機の打ち込み部に連結ネジを案内供給する機構が提案されている（実願 昭４ー６７１２９号）。 A screw tightener that uses a connecting screw made by connecting multiple screws at regular intervals to a connecting band made of synthetic resin is easy to bend because the rigidity of the connecting band is low. Therefore, a mechanism has been proposed in which a guide member for accommodating the connecting screw is attached to the body of the screw tightener, and the connecting screw is guided and supplied from the guide passage of the guide member to the driving portion of the screw tightener (Practical application Sho 4-. 67129).
【０００３】 しかしながら、上記案内通路はネジの打ち込み方向と平行に形成され、また連 結ネジは案内通路内に自由に移動できるように形成されていたので、ネジ締め機 を下向きにすると、案内通路内の連結ネジが簡単に案内通路から抜け出てずり落 ちてしまい、ネジ締め作業の障害になるとともに、連結ネジの送り不良の原因と なる欠点があった。However, since the guide passage is formed parallel to the screw driving direction and the connecting screw is formed so as to be freely movable in the guide passage, when the screw tightener is turned downward, the guide passage is The connecting screw inside easily slips out of the guide passage and slips off, which hinders the screw tightening work and causes a problem in feeding the connecting screw.
【０００４】[0004]
本考案は前記欠点を解消し、特にネジ締め機をどのような方向に向けても連結 ネジがずり落ちるのを有効に防止することができる連結ネジのずり落ち防止機構 を提供することをその目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks, and in particular to provide a mechanism for preventing a connecting screw from slipping off, which can effectively prevent the connecting screw from slipping off in any direction of a screw tightener. To do.
【０００５】[0005]
前記目的を達成するため、本考案に係るネジ締め機における連結ネジのずり落 ち防止機構は、連結ネジをネジ打ち込み部に案内供給する案内通路を備えたガイ ド部材をネジ締め機本体に付設したネジ締め機において、上記案内通路には、連 結ネジの軸部をはさんで対向する一対のストッパを回動自在に軸着支持した摺動 部材を連結ネジの供給方向に沿って摺動自在でかつ連結ネジの供給方向と逆側に バネ付勢して配置し、前記一対のストッパは、両ストッパの端部が上記案内通路 内の上記ネジ軸と係合する張り出し位置と、上記案内通路内でのネジ軸の通過を 可能とする退避位置との間に回転が可能であり、かつ常時案内通路内に張り出す ようにバネ付勢させられており、上記案内通路には、上記摺動部材がネジ供給方 向に摺動したときに上記両ストッパの端面に係合して上記両ストッパの退避位置 への回動を阻止する停止壁を形成したことを特徴とする。 In order to achieve the above-mentioned object, the mechanism for preventing the connecting screw from slipping off in the screw tightening machine according to the present invention is provided with a guide member having a guide passage for guiding the connecting screw to the screw driving part in the screw tightening machine body. In the screw tightening machine described above, a sliding member, which is rotatably supported by a pair of stoppers that sandwich the shaft portion of the connecting screw, is slidable in the guide passage along the supply direction of the connecting screw. The stoppers are freely spring-biased in the opposite direction to the supply direction of the connecting screw, and the pair of stoppers are provided with an extension position where the ends of both stoppers engage with the screw shaft in the guide passage and the guide. It is rotatable between the retracted position that allows passage of the screw shaft in the passage, and is always spring-biased so as to project into the guide passage.

【０００６】[0006]
ネジ締め機本体を横向き又は上向きにして行なう通常のネジ締め時には、摺動 部材は連結ネジの供給方向と逆側に付勢され、このとき一対のストッパは張り出 し位置にあるから、連結ネジが送り機構により打ち込み部に供給されるときにス トッパの端部は各ネジのネジ軸に係合するが、連結ネジの送り力によりバネ付勢 に抗してネジ軸の通過を可能とする退避位置に回動する。連結ネジを作業の途中 でガイド部材の後端から抜き出す場合も、同様にして張り出し位置にあるストッ パを退避位置に回動させて連結ネジを引き出すことができる。 During normal screw tightening with the main body of the screw tightener facing sideways or upward, the sliding member is biased in the direction opposite to the supply direction of the connecting screw, and at this time, the pair of stoppers are in the projecting position, so the connecting screw The end of the stopper engages with the screw shaft of each screw when is fed to the driving part by the feed mechanism, but the screw shaft can be passed against the spring bias by the feed force of the connecting screw. Rotate to the retracted position. Even when the connecting screw is pulled out from the rear end of the guide member during the work, the connecting screw can be similarly pulled out by rotating the stopper at the projecting position to the retracted position.
【０００７】 これに対し、ネジ締め機本体を下向きにすると、摺動部材は重力によって連結 ネジ供給方向に摺動し、その摺動端でストッパの端面は停止壁に係合する。摺動 時にストッパは張り出し位置にあるから、停止壁に係合したときにストッパは張 り出し位置に保持される。このため、ネジ軸はストッパの端部に係合し、それ以 上下方に（前方に）移動することはできない。On the other hand, when the screw tightener main body is turned downward, the sliding member slides in the connecting screw supply direction by gravity, and the end face of the stopper engages with the stop wall at the sliding end. Since the stopper is in the extended position when sliding, the stopper is held in the extended position when it engages with the stop wall. Therefore, the screw shaft engages with the end portion of the stopper and cannot move further downward (forward).

The guide passage 6 is formed so that the upper portion 6a is wide enough to accommodate the connecting band a and the lower portion 6b is narrow enough to accommodate the screw shaft.
【００１０】 上記ガイド部材５には、ネジ締め機本体４を下向きにしても連結ネジ１がマガ ジン３からずり落ちないようにするずり落ち防止機構が設けられている。The guide member 5 is provided with a slip-off prevention mechanism that prevents the connecting screw 1 from slipping off from the magazine 3 even when the screw tightener body 4 faces downward.
【００１１】 すなわち、案内通路６の前部には切欠き部７が形成され、該切欠き部７には摺 動部材８が連結ネジ１の供給方向に摺動可能に配置されている。摺動部材８は案 内通路６の内面に沿うように断面が下向き開口のＣ字形に形成されている。そし て、摺動部材８の上片８ａの後部には係合片９が形成され、該係合片９とガイド 部材５には引っ張りバネ１０が取り付けられ、摺動部材８は引っ張りバネ１０に より連結ネジ１の供給方向と逆側にバネ付勢されている。なお、引っ張りバネ１ ０のバネ力はネジ締め機本体４を下向きにしたときに摺動部材８が重力によって 下方に摺動するのを妨げない程度とする。That is, a notch portion 7 is formed in the front portion of the guide passage 6, and a sliding member 8 is arranged in the notch portion 7 so as to be slidable in the supply direction of the connecting screw 1. The sliding member 8 is formed in a C-shape having a downward opening in cross section along the inner surface of the proposed passage 6. Then, an engaging piece 9 is formed at the rear of the upper piece 8a of the sliding member 8, a tension spring 10 is attached to the engaging piece 9 and the guide member 5, and the sliding member 8 is attached to the tension spring 10. The spring is biased in the direction opposite to the supply direction of the connecting screw 1. The spring force of the tension spring 10 is set so as not to prevent the sliding member 8 from sliding downward due to gravity when the screw tightener main body 4 is turned downward.
【００１２】 また、上記上片８ａの前部にはスチールボール１１の係合孔１２が形成されて いる。この係合孔１２は案内通路６の上壁に斜め前方に形成されたスチールボー ル１１の受け溝１３に対応し、摺動部材８が引っ張りバネ１０のバネ力によって 切欠き部７の後方に位置しているときは、スチールボール１１が上記係合孔１２ と受け溝１３の両側に半分ずつ係合し、摺動部材８の摺動を阻止するように構成 されている。An engaging hole 12 for a steel ball 11 is formed in the front portion of the upper piece 8a. The engaging hole 12 corresponds to the receiving groove 13 of the steel ball 11 formed obliquely forward on the upper wall of the guide passage 6, and the sliding member 8 is moved to the rear of the notch portion 7 by the spring force of the tension spring 10. When located, the steel balls 11 are engaged with the engaging holes 12 and the receiving grooves 13 in half halves to prevent the sliding member 8 from sliding.
【００１３】 次に、図５に示すように、摺動部材８の下片８ｂ、８ｃは２段に形成され、前 端部の下片８ｂは他の下片８ｃよりも下方に形成され、上記前端部両側の下片８ ｂには一対のストッパ１４が連結ネジ１のネジ軸ｂ１をはさんで対向して設けら れている。各ストッパ１４は下片８ｂに固定された支持ピン１５に回動自在に軸 着支持されている。Next, as shown in FIG. 5, the lower pieces 8b and 8c of the sliding member 8 are formed in two steps, and the lower piece 8b of the front end is formed below the other lower piece 8c. A pair of stoppers 14 are provided on the lower pieces 8b on both sides of the front end so as to face each other with the screw shaft b1 of the connecting screw 1 interposed therebetween. Each stopper 14 is rotatably supported by a support pin 15 fixed to the lower piece 8b.
【００１４】 ストッパ１４は平面視略方形の板状に形成され、スペーサ１６により上部下片 ８ｃと同じ高さ位置に配置されている。また、支持ピン１５には各ストッパ１４ の中心より片寄り側に設けられ、 前記一対のストッパ１４は、その端部１４ａが案内通路６内の連結ネジ１のネ ジ軸ｂ１に係合する張り出し位置（図４の位置）と、案内通路６内でのネジ軸ｂ １の通過を可能とする退避位置（図６(b) 、図７(b) の位置）との間で回転可能 に設けられている。また、各ストッパ１４は、支持ピン１５に巻き付けられた捩 りコイルバネ１７により常時案内通路６内に張り出すようにバネ付勢されている 。なお、ストッパ１４が張り出したときは、両ストッパ１４の端部１４ａの前後 面がハの字形になるように形成されている。The stopper 14 is formed in a substantially rectangular plate shape in a plan view, and is arranged at the same height position as the upper lower piece 8c by a spacer 16. Further, the support pin 15 is provided on one side closer to the center of each stopper 14, and the pair of stoppers 14 has an end portion 14a which is extended so as to engage with the screw shaft b1 of the connecting screw 1 in the guide passage 6. It is rotatably provided between the position (position in FIG. 4) and the retracted position (position in FIGS. 6 (b) and 7 (b)) that allows the screw shaft b 1 to pass through in the guide passage 6. Has been. Further, each stopper 14 is spring-biased by a torsion coil spring 17 wound around a support pin 15 so as to always extend into the guide passage 6. When the stoppers 14 project, the front and rear surfaces of the end portions 14a of the stoppers 14 are formed in a V shape.
【００１５】 さらに、上記案内通路６の切欠き部７の前端には、摺動部材８がネジ供給方向 に摺動したときに上記両ストッパ１４の端面に係合する停止壁１８が形成されて いる。ストッパ１４の端面が停止壁１８に係合すると、ストッパ１４の回動は阻 止される。Further, at the front end of the cutout portion 7 of the guide passage 6, there is formed a stop wall 18 that engages with the end faces of the stoppers 14 when the sliding member 8 slides in the screw feeding direction. There is. When the end surface of the stopper 14 is engaged with the stop wall 18, the rotation of the stopper 14 is blocked.
【００１６】 次に、前記構成のネジ締め機の使用態様について説明すると、まずガイド部材 ５の後端から連結ネジ１を装填し、連結ネジ１の前端を打ち込み部２にセットし 、その後ネジ締めする。ネジ締め機本体４を横向き又は上向きにして行なう通常 のネジ締め時には、摺動部材８は引っ張りバネ１０とスチールボール１１によっ て後方位置に保持される。この場合、一対のストッパ１４は張り出し位置にある から、図６(a) (b) に示されるように、連結ネジ１が送り機構により打ち込み部 ２に供給されるときにストッパ１４の端部１４ａは各ネジのネジ軸ｂ１に係合す るが、連結ネジ１の送り力により捩りコイルバネ（１７）のバネ力に抗してネジ 軸ｂ１の通過を可能とする退避位置に回動する。Next, the usage mode of the screw tightening machine having the above-mentioned configuration will be described. First, the connecting screw 1 is loaded from the rear end of the guide member 5, the front end of the connecting screw 1 is set in the driving part 2, and then the screw tightening is performed. To do. During normal screw tightening performed with the screw tightener body 4 facing sideways or upward, the sliding member 8 is held at the rear position by the tension spring 10 and the steel ball 11. In this case, since the pair of stoppers 14 are in the projecting position, as shown in FIGS. 6 (a) and 6 (b), when the connecting screw 1 is supplied to the driving portion 2 by the feeding mechanism, the end portions 14a of the stoppers 14 are Engages with the screw shaft b1 of each screw, but is rotated to the retracted position that allows passage of the screw shaft b1 against the spring force of the torsion coil spring (17) by the feed force of the connecting screw 1.
【００１７】 また、連結ネジ１が全部消費される前に他の連結ネジ１と交換する必要がある ときなどには、ガイド部材５に装填された連結ネジ１を作業の途中でガイド部材 ５の後端から抜き出す必要がある。この場合は、図７(a) (b) に示されるように 、連結ネジ１の引き出し力が捩りコイルバネ（１７）のバネ力よりも大きくする ことにより張り出し位置にあるストッパ１４はネジ軸ｂ１の通過を可能とする退 避位置に回動させて連結ネジ１を引き出すことができる。In addition, when it is necessary to replace the connecting screw 1 with another connecting screw 1 before the connecting screw 1 is completely consumed, the connecting screw 1 loaded in the guide member 5 may be removed from the guide member 5 during the work. It is necessary to pull it out from the rear end. In this case, as shown in FIGS. 7 (a) and (b), the pulling force of the connecting screw 1 is made larger than the spring force of the torsion coil spring (17), so that the stopper 14 at the projecting position is fixed to the screw shaft b1. The connecting screw 1 can be pulled out by rotating it to a retracted position that allows passage.
【００１８】 これに対し、作業者がネジ締め機本体４を下向きにすると、スチールボール１ １は受け溝１３の内部に移動してしまうので、摺動部材８は引っ張りバネ１０の バネ力に抗し、重力によって下方（連結ネジ供給方向）に摺動する。そして、図 ８に示されるように、その摺動端でストッパ１４の端面１４ｂは停止壁１８に係 合する。摺動時にストッパ１４は張り出し位置にあるから、停止壁１８に係合し たときにストッパ１４は張り出し位置に保持される。このため、ネジ軸ｂ１はス トッパ１４の端部１４ａに係合し、それ以上下方に（前方に）移動することはで きない。したがって、連結ネジ１のずり落ちは有効に防止される。このため、下 向きのネジ締め作業も行なうことができる。On the other hand, when the operator turns the screw tightener main body 4 downward, the steel ball 11 moves into the receiving groove 13, so that the sliding member 8 resists the spring force of the tension spring 10. Then, due to gravity, it slides downward (connecting screw supply direction). Then, as shown in FIG. 8, the end surface 14 b of the stopper 14 engages with the stop wall 18 at its sliding end. Since the stopper 14 is in the projecting position when sliding, the stopper 14 is held in the projecting position when engaged with the stop wall 18. Therefore, the screw shaft b1 engages with the end portion 14a of the stopper 14 and cannot move further downward (forward). Therefore, slippage of the connecting screw 1 is effectively prevented. For this reason, downward screw tightening work can also be performed.
