Description

本発明は、締付部材、例えばボルトやナット、ネジ等を１個ずつ供給位置まで移動させ、外部の締付部材締付機構に供給する締付部材供給機構に関する。   The present invention relates to a tightening member supply mechanism that moves a tightening member, such as a bolt, a nut, and a screw, one by one to a supply position and supplies the tightening member to an external tightening member tightening mechanism.

従来、上記締付部材供給機構として、複数の締付部材を整列保持する振動式ねじ供給ユニット３及びシュートレール４と、そのシュートレール４から排出される締付部材をねじ締めユニット１０（締付部材締付機構）への供給位置まで移動させるシャトル部材４０とを備えたものが知られている（例えば、特許文献１参照。）。
特開昭６１−２１９５７９号公報 Conventionally, as the tightening member supply mechanism, a vibration type screw supply unit 3 and a chute rail 4 that align and hold a plurality of tightening members, and a tightening member that is discharged from the chute rail 4 are screw tightening units 10 (tightening). A device including a shuttle member 40 that moves to a supply position to a member tightening mechanism is known (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 61-219579

しかし、上記従来の締付部材供給機構では、振動式ねじ供給ユニット３及びシュートレール４、シャトル部材４０で構成される機構が複雑なため大型化する。具体的には、シュートレール４による締付部材の整列保持方向とシャトル部材４０の移動方向が直交しており、また、振動式ねじ供給ユニット３とねじ締めユニット１０との干渉を避けるためにシャトル部材４０の移動幅が大きくなるので、この機構の占有するスペースが大きくなる。   However, the conventional fastening member supply mechanism is increased in size because the mechanism including the vibration type screw supply unit 3, the chute rail 4, and the shuttle member 40 is complicated. Specifically, the direction in which the fastening members are aligned and held by the chute rail 4 and the movement direction of the shuttle member 40 are orthogonal to each other, and in order to avoid interference between the vibration screw supply unit 3 and the screw fastening unit 10, Since the movement width of the member 40 is increased, the space occupied by this mechanism is increased.

そのため、この締付部材供給機構を締付部材締付装置等に組み込む場合、締付部材締付装置の他の機構、例えば、締付部材締付機構等と干渉しないようにする必要があるため、装置の設計の自由度が低くなるか、あるいは各機構の作動が限定されてしまうといった問題がある。   Therefore, when this tightening member supply mechanism is incorporated into a tightening member tightening device or the like, it is necessary not to interfere with other mechanisms of the tightening member tightening device, such as the tightening member tightening mechanism. There is a problem that the degree of freedom in designing the apparatus is reduced, or the operation of each mechanism is limited.

そこで本発明は、上記の問題点に鑑み、機構が簡単で小型化でき、締付部材締付装置等に組み込む場合に、装置の設計の自由度が低くならず、装置内の各機構の作動が制限されない締付部材供給機構を提供することを課題とする。   Therefore, in view of the above problems, the present invention can reduce the degree of freedom in designing the device when the mechanism is simple and can be miniaturized and incorporated in a fastening member fastening device or the like. It is an object of the present invention to provide a fastening member supply mechanism that is not limited.

上記課題を解決するために請求項１記載の発明は、締付部材を１個ずつ供給位置まで移動させ、外部の締付部材締付機構に供給する締付部材供給機構において、複数の締付部材を、それらの中心軸を上記締付部材締付機構の締付方向と平行にした姿勢で、且つ一列に整列した状態でスライド自在に保持するスライド保持手段であって、その整列方向一端側に締付部材を外部に排出する排出部を有すると共に、他端側に締付部材を外部から補充する補充部を有するスライド保持手段と、上記スライド保持手段の排出部から排出される締付部材を、スライド保持手段に保持されている姿勢と同姿勢で受け取って保持する受取保持手段であって、上記排出部から排出される締付部材を受け取り、上記締付部材締付機構に締付部材を供給する、排出部に近接した上記供給位置と、作動時の締付部材締付機構と干渉しないように排出部から離間した待避位置との間で移動自在に構成された受取保持手段と、上記スライド保持手段に保持されている締付部材を１個ずつ受取保持手段に送り込む締付部材ピッチ送り手段と、を備えていることを特徴としている。   In order to solve the above-described problem, the invention described in claim 1 is directed to a plurality of tightening members in a tightening member supply mechanism that moves the tightening members one by one to a supply position and supplies the tightening members to an external tightening member tightening mechanism. Slide holding means for holding members slidably in a state where their central axes are parallel to the tightening direction of the tightening member tightening mechanism and aligned in a row, one end side in the alignment direction Slide holding means having a discharge portion for discharging the tightening member to the outside and a replenishment portion for replenishing the tightening member from the outside on the other end side, and a tightening member discharged from the discharge portion of the slide holding means Receiving and holding means for receiving and holding the same in the same posture as that held by the slide holding means, receiving a tightening member discharged from the discharge portion, and receiving the tightening member in the tightening member tightening mechanism Supply the discharge part A receiving and holding means configured to be movable between the adjacent supply position and a retracted position separated from the discharge portion so as not to interfere with a fastening member fastening mechanism during operation; and held by the slide holding means. And fastening member pitch feeding means for feeding the fastening members one by one to the receiving and holding means.

また、請求項２記載の発明は、請求項１に記載の締付部材供給機構において、上記締付部材ピッチ送り手段は、スライド保持手段に保持されている締付部材のうち最も補充部に近い締付部材を排出部方向に常時押圧する第１押圧手段と、スライド保持手段に保持されている締付部材のうち最も排出部に近い締付部材の排出部方向への移動を規制可能な第１規制手段と、２個以上の締付部材がスライド保持手段に保持されている場合に、２番目に排出部に近い締付部材の排出部方向への移動を規制可能な第２規制手段と、上記最も排出部に近い締付部材を排出部方向に押圧して上記供給位置まで移動させる第２押圧手段と、を備えていることを特徴とする。   According to a second aspect of the present invention, in the tightening member supply mechanism according to the first aspect, the tightening member pitch feeding means is closest to the replenishing portion among the tightening members held by the slide holding means. The first pressing means that always presses the tightening member in the direction of the discharge portion, and the first of the tightening members that are held by the slide holding means can restrict the movement of the tightening member closest to the discharge portion in the direction of the discharge portion. A first restricting means, and a second restricting means capable of restricting movement of the tightening member closest to the discharge portion toward the discharge portion when two or more tightening members are held by the slide holding means; And a second pressing means for pressing the fastening member closest to the discharge portion in the discharge portion direction to move to the supply position.

上記請求項１記載の発明によれば、スライド保持手段に保持された複数の締付部材が、締付部材ピッチ送り手段によって１個ずつ受取保持手段に送り込まれ、その受取保持手段が締付部材を受け取った位置、すなわち供給位置で締付部材締付機構に供給される。そして、締付部材締付機構が締付部材を受け取った後には、受取保持手段が締付部材締付機構と干渉しない待避位置まで移動する。   According to the first aspect of the present invention, the plurality of fastening members held by the slide holding means are fed to the receiving holding means one by one by the fastening member pitch feeding means, and the receiving holding means is the fastening member. Is supplied to the tightening member tightening mechanism at the receiving position, that is, the supply position. Then, after the tightening member tightening mechanism receives the tightening member, the receiving holding means moves to a retracted position where it does not interfere with the tightening member tightening mechanism.

そのため、スライド保持手段からの締付部材の排出位置が締付部材締付機構への締付部材の供給位置となるので、上記従来の締付部材供給機構のようにシャトル部材の移動幅といったスペースを要せず、機構を小型化することができる。したがって、締付部材供給機構を締付部材締付装置等に組み込む場合に、装置の設計の自由度が低くならず、装置内の各機構の作動が制限されない。   For this reason, the discharge position of the tightening member from the slide holding means becomes the supply position of the tightening member to the tightening member tightening mechanism, so that the space such as the movement width of the shuttle member as in the conventional tightening member supply mechanism described above. Therefore, the mechanism can be downsized. Therefore, when the fastening member supply mechanism is incorporated in a fastening member fastening device or the like, the degree of freedom in designing the device is not lowered, and the operation of each mechanism in the device is not restricted.

また、上記請求項２記載の発明によれば、第１規制手段で最も排出部に近い締付部材の排出部方向への移動を規制すると共に、第２規制手段の規制を解除し、第１押圧手段の押圧を行うことによって、締付部材がスライド保持手段にセットされる。次に、第１押圧手段の押圧を持続した状態で、第２規制手段で２番目に排出部に近い締付部材の排出部方向への移動を規制し、その後、第１規制手段の規制を解除することにより、最も排出部に近い締付部材のみの排出部方向への移動を可能とする。続いて、第２押圧手段によってその最も排出部に近い締付部材を排出部方向に押圧することにより、その締付部材を受取保持手段に送り込む。以上の動作を繰り返し行うことにより、スライド保持手段に保持されている締付部材を１個ずつ供給位置まで移動させることができる。   According to the second aspect of the invention, the first restricting means restricts the movement of the tightening member closest to the discharge part in the direction of the discharge part, and the restriction of the second restricting means is canceled, By pressing the pressing means, the tightening member is set on the slide holding means. Next, in a state where the pressing of the first pressing means is continued, the second restricting means restricts the movement of the tightening member second closest to the discharging part toward the discharging part, and then the first restricting means is restricted. By releasing, only the fastening member closest to the discharge part can be moved in the discharge part direction. Subsequently, the fastening member closest to the discharge portion is pressed in the direction of the discharge portion by the second pressing means, thereby feeding the tightening member into the receiving and holding means. By repeating the above operation, the fastening members held by the slide holding means can be moved one by one to the supply position.

The groove width is narrowed over the stages, and the groove width on the discharge part 201a side is substantially equal to the outer diameter of the head part Na of the flange nut N. As a result, the phase of the flange nut N replenished from the replenishment portion 201b of the slide holding member 201 with an arbitrary head portion Na phase by an external parts feeder (not shown) is gradually adjusted by the head portion guide groove 203. The The opposing outer peripheral surfaces of the head portions Na of the three flange nuts N close to the discharge portion 201a are in contact with the inner peripheral surfaces of the upper contact members 201 1 and 201 2 , respectively, and the flange nut N is held at a predetermined phase.

At the same time, the piston rod 205a of the cylinder 205 is projected, receiving the holding member 202 moves spaced a standby position P 2 from the discharge portion 201a. When the movement of the payout pawl support member 222 and the receiving and holding member 202 is completed, the piston rod 215a of the cylinder 215 is retracted after the piston rod 214a of the cylinder 214 protrudes. As a result, the three flange nuts N whose movement in the direction of the discharge portion 201a is restricted by the restriction member 217 are pressed and slid by the feed claws 211 in the direction of the discharge portion 201a. Then, the movement of the flange nut N in the direction of the discharge portion 201a that is closest to the discharge portion 201a by this slide is restricted by the restriction member 216, and consequently the movement of the three flange nuts N in the direction of the discharge portion 201a is restricted. .

このシリンダ２１４，２１５の作動と並行して、図１２に示すように、シリンダ３１２のピストンロッド３１２ａが没入し、回転係合部材３０２の係合部３０２2ｂがフランジナットＮをボルトＢに締め付け開始する締付位置Ｐ5まで移動する。 In parallel with the operation of the cylinder 214 and 215, as shown in FIG. 12, the piston rod 312a of the cylinder 312 is retracted, the clamping engagement portion 302 2 b of the rotary engaging member 302 is a flange nut N on the bolt B move to the position P 5 tightening to start.

続いて、図１３を参照して、回転作動駆動源３０４を駆動して回転係合部材３０２を低速回転させ、係合部３０２2ｂに係合しているフランジナットＮとボルトＢとを嵌合させる。フランジナットＮとボルトＢとが嵌合したら、回転作動駆動源３０４の駆動によって回転係合部材３０２を中速回転させ、フランジナットＮのボルトＢに対する仮締め及び本締めを行う。このとき、ボルトＢがナット保持部３０２2の内部に進入してくるが、マグネット３０９及びマグネット支持部材３０７がバネ３０８の付勢力に抗して上部に移動することにより、フランジナットＮをボルトＢに対して最後まで締め付けることができる。 Subsequently, referring to FIG. 13, the rotation actuation drive source 304 is driven to rotate the rotation engagement member 302 at a low speed, and the flange nut N and the bolt B engaged with the engagement portion 302 2 b are fitted. Combine. When the flange nut N and the bolt B are fitted, the rotation engaging member 302 is rotated at a medium speed by driving the rotational operation drive source 304, and the bolt N of the flange nut N is temporarily tightened and finally tightened. At this time, the bolt B comes to enter the interior of the nut holding portion 302 2, by the magnet 309 and the magnet support member 307 is moved to the upper against the biasing force of the spring 308, the flange nut N bolts B Can be tightened to the end.

このようにして１個のフランジナットＮのボルトＢへの締付け作業が終わると、シリンダ３１０のピストンロッド３１０ａが没入すると共にシリンダ３１２のピストンロッド３１２ａが突出し、回転係合部材３０２の係合部３０２2ｂが待機位置Ｐ4（図１参照）まで移動する。そして、スライド保持部材２０１に保持されているフランジナットが無くなるまで同様の動作が繰り返される。 When the tightening operation of one flange nut N to the bolt B is completed in this way, the piston rod 310a of the cylinder 310 is retracted and the piston rod 312a of the cylinder 312 protrudes, and the engaging portion 302 of the rotary engaging member 302 is inserted. 2 b is moved to the standby position P 4 (see FIG. 1). Then, the same operation is repeated until the flange nut held by the slide holding member 201 disappears.
