以下、添付図面に即してこの発明に係る継ぎ手挿入治具を実施するための形態について説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for implementing a joint insertion jig according to the present invention will be described with reference to the accompanying drawings.

図１はこの発明の実施例に係る継ぎ手挿入治具の斜視図であり、図２は継ぎ手挿入治具で使用されるチューブおよび継ぎ手を説明するための説明図である。   FIG. 1 is a perspective view of a joint insertion jig according to an embodiment of the present invention, and FIG. 2 is an explanatory view for explaining a tube and a joint used in the joint insertion jig.

図１において符号１０は継ぎ手挿入治具を示す。継ぎ手挿入治具１０は、ベース１２と、ベース１２に支持され、チューブｔを保持するチューブ保持部１４と、同じくベース１２に支持され、継ぎ手ｃを保持する継ぎ手保持部１６とを備える。   In FIG. 1, reference numeral 10 denotes a joint insertion jig. The joint insertion jig 10 includes a base 12, a tube holding part 14 that is supported by the base 12 and holds the tube t, and a joint holding part 16 that is also supported by the base 12 and holds the joint c.

図２に示すように、継ぎ手挿入治具１０で使用されるチューブｔは断面視略クランク状を呈すると共に、中間位置に円盤部ｔ１を有する。また、継ぎ手ｃはＬ字状に屈曲し、一方の端部が継ぎ手挿入治具１０によってチューブｔの一端に挿入される。   As shown in FIG. 2, the tube t used in the joint insertion jig 10 has a substantially crank shape in a sectional view and has a disk portion t1 at an intermediate position. Further, the joint c is bent in an L shape, and one end thereof is inserted into one end of the tube t by the joint insertion jig 10.

図１の説明に戻ると、ベース１２は、チューブ保持部１４および継ぎ手保持部１６を設置するための金属製の板状部材であり、平面視長方形状を呈する。ベース１２には、上面の一方の端部付近から垂直方向に延びるストッパ１８と、ストッパ１８から長辺に沿って水平方向に延びる円柱状の２本のガイド２０が互いに所定距離離れて並行に設けられる。   Returning to the description of FIG. 1, the base 12 is a metal plate-like member for installing the tube holding portion 14 and the joint holding portion 16 and has a rectangular shape in plan view. The base 12 is provided with a stopper 18 extending in the vertical direction from the vicinity of one end portion of the upper surface and two cylindrical guides 20 extending in the horizontal direction along the long side from the stopper 18 in parallel with a predetermined distance from each other. It is done.

チューブ保持部１４は、ブロック状の台部材２２からなるが、より具体的には、継ぎ手挿入治具１０を側面から見たときに、水平方向に延びる水平部２２ａと垂直方向に伸びる垂直部２２ｂからなる断面視略Ｔ字状を呈する樹脂性の部材である。   The tube holding portion 14 includes a block-shaped base member 22. More specifically, when the joint insertion jig 10 is viewed from the side surface, the horizontal portion 22 a extending in the horizontal direction and the vertical portion 22 b extending in the vertical direction are seen. It is the resin-like member which exhibits cross-sectional view substantially T-shape consisting of.

台部材２２の垂直部２２ｂには、２本のガイド２０が貫通しており、台部材２２はガイド２０の軸方向に沿って移動可能なように構成される。   Two guides 20 pass through the vertical portion 22 b of the base member 22, and the base member 22 is configured to be movable along the axial direction of the guide 20.

台部材２２（水平部２２ａ）の上面にはチューブｔを所定の向きに案内し、固定するためのチューブ固定溝２２ｃが形成される。尚、「所定の向き」とは、チューブｔの軸方向がガイド２０の軸方向と略一致する向きを意味する。   A tube fixing groove 22c for guiding and fixing the tube t in a predetermined direction is formed on the upper surface of the base member 22 (horizontal portion 22a). The “predetermined direction” means a direction in which the axial direction of the tube t substantially coincides with the axial direction of the guide 20.

チューブ固定溝２２ｃはチューブｔの形状に合わせて台部材２２の上面に凹状に形成されるが、チューブ固定溝２２ｃの略中央位置付近にはチューブｔを固定する（上方から押える）ためのチューブ固定爪（図示せず）が形成され、ここでチューブｔは固定される。チューブｔは上記の通り、中間位置に円盤部ｔ１を有するため、この実施例では、円盤部ｔ１を押えるようにチューブ固定爪が設けられる。   The tube fixing groove 22c is formed in a concave shape on the upper surface of the base member 22 in accordance with the shape of the tube t. However, the tube fixing for fixing (pressing from above) the tube t near the approximate center position of the tube fixing groove 22c. A claw (not shown) is formed, where the tube t is fixed. As described above, since the tube t has the disk part t1 at the intermediate position, in this embodiment, the tube fixing claw is provided so as to press the disk part t1.

継ぎ手保持部１６は、チューブ保持部１４に対向して配置され、チューブ保持部１４に保持されたチューブｔの軸心と同軸上または略同軸上に継ぎ手ｃの軸心が位置するように継ぎ手ｃを保持する。   The joint holding portion 16 is disposed so as to face the tube holding portion 14, and the joint c is positioned so that the axial center of the joint c is coaxially or substantially coaxial with the axial center of the tube t held by the tube holding portion 14. Hold.

継ぎ手保持部１６は、チューブ保持部１４と同様、ブロック状の台部材２４からなるが、より具体的な形状はチューブ保持部１４とは異なり略立方体を呈している。   The joint holding portion 16 includes a block-shaped base member 24 as in the tube holding portion 14, but has a more specific shape that is substantially a cube, unlike the tube holding portion 14.

継ぎ手保持部１６のチューブ保持部１４と対向する面の下方には、ガイド２０の端部が固定される。   The end portion of the guide 20 is fixed below the surface of the joint holding portion 16 facing the tube holding portion 14.

継ぎ手保持部１６の上面には継ぎ手ｃを固定するための継ぎ手固定台２４ａが台部材２４から取り外し可能に設けられる。継ぎ手固定台２４ａのチューブ保持部１４と対向する面には、継ぎ手ｃの形状（図２に示すＬ字状の継ぎ手以外に例えばＩ字状の継ぎ手など）に応じた溝が切られており、この溝に継ぎ手ｃをガイド２０の軸方向から差し込んでセットできるようになっている。   A joint fixing base 24 a for fixing the joint c is detachably provided on the upper surface of the joint holding portion 16 from the base member 24. A groove corresponding to the shape of the joint c (for example, an I-shaped joint in addition to the L-shaped joint shown in FIG. 2) is cut on the surface of the joint fixing base 24a facing the tube holding portion 14. The joint c can be inserted into the groove from the axial direction of the guide 20 and set.

継ぎ手ｃをガイド２０の軸方向から差し込む構成とすることで、継ぎ手ｃにチューブｔが挿入された後、チューブ保持部１４を元の位置に戻せばチューブｔが挿入された継ぎ手ｃを継ぎ手固定台２４ａから取り出すことができる。但し、継ぎ手ｃの軸心がチューブ保持部１４に保持されたチューブｔの軸心と同軸上または略同軸上に位置するように固定できるのであれば、継ぎ手ｃの固定方法は上記の方法に限定されない。   By adopting a configuration in which the joint c is inserted from the axial direction of the guide 20, after the tube t is inserted into the joint c, the tube c is inserted into the joint fixing base by returning the tube holding portion 14 to the original position. 24a can be taken out. However, the fixing method of the joint c is limited to the above method as long as the axis of the joint c can be fixed so as to be positioned coaxially or substantially coaxially with the axial center of the tube t held by the tube holding portion 14. Not.

次いで、この実施例に係る継ぎ手挿入治具１０の動作について説明する。図３は継ぎ手挿入治具において、継ぎ手にチューブを挿入する様子を説明するための説明図である。   Next, the operation of the joint insertion jig 10 according to this embodiment will be described. FIG. 3 is an explanatory diagram for explaining how the tube is inserted into the joint in the joint insertion jig.

先ず、図３（ａ）に示すように、チューブ保持部１４および継ぎ手保持部１６にそれぞれチューブｔと継ぎ手ｃをセットしたら、チューブ保持部１４をガイド２０に沿って移動させる。尚、この実施例では、作業者がチューブ保持部１４を手動で移動させる。   First, as shown in FIG. 3A, when the tube t and the joint c are set in the tube holding part 14 and the joint holding part 16, respectively, the tube holding part 14 is moved along the guide 20. In this embodiment, the operator manually moves the tube holding portion 14.

次いで、図３（ｂ）に示すように、チューブ保持部１４が所定距離移動して所定位置に到達するとエア供給部３０からチューブｔの内部（内筒部）にエアが供給される（チューブｔの継ぎ手ｃが挿入される側の端部ｔ２とは反対側の端部ｔ３からチューブｔの内部に向けてエアが供給される）。   Next, as shown in FIG. 3B, when the tube holding part 14 moves a predetermined distance and reaches a predetermined position, air is supplied from the air supply part 30 to the inside (inner cylinder part) of the tube t (tube t Air is supplied from the end t3 on the side opposite to the end t2 on the side where the joint c is inserted into the tube t).

エア供給部３０からチューブｔの内部にエアが供給されると、チューブｔの内径は拡径されるので、チューブｔを継ぎ手ｃに挿入し易くなる。   When air is supplied from the air supply unit 30 to the inside of the tube t, the inner diameter of the tube t is increased, so that the tube t can be easily inserted into the joint c.

エア供給部３０は、エア供給源（図示せず）と、エア吐出口３０ａと、エア供給源とエア吐出口３０ａとを接続するエア供給路３０ｂと、エア供給路３０ｂに介挿され、エア供給源とエア吐出口３０ａとの連通／遮断を切り替える２ポートの切替バルブ（メカニカルエアバルブ）３０ｃとからなる。   The air supply unit 30 is inserted into an air supply source (not shown), an air discharge port 30a, an air supply path 30b connecting the air supply source and the air discharge port 30a, and the air supply path 30b. It comprises a two-port switching valve (mechanical air valve) 30c for switching communication / blocking between the supply source and the air discharge port 30a.

エア供給源とエア吐出口３０ａとの連通／遮断の切り替えは、切替バルブ３０ｃに設けられたスイッチ３０ｄのオン／オフによって行われる。切替バルブ３０ｃは、スイッチ３０ｄがオンされるとエア供給源とエア吐出口３０ａとを連通させ、スイッチ３０ｄがオフのときはエア供給源とエア吐出口３０ａとの連通を遮断する。   Switching between communication / blocking between the air supply source and the air discharge port 30a is performed by turning on / off a switch 30d provided in the switching valve 30c. The switching valve 30c allows the air supply source and the air discharge port 30a to communicate with each other when the switch 30d is turned on, and blocks the communication between the air supply source and the air discharge port 30a when the switch 30d is off.

切替バルブ３０ｃは、チューブ保持部１４が移動していない状態（図３（ａ）の状態）において、チューブ保持部１４と継ぎ手保持部１６との間であって、ガイド２０の側方に設置される。そして、切替バルブ３０ｃは、チューブ保持部１４が所定距離移動したとき、台部材２２、より具体的には、チューブ保持部１４の移動方向と直交する側の台部材２２の垂直部２２ｂの一方の壁面によってスイッチ３０ｄがオンされる位置に設置される。   The switching valve 30c is installed on the side of the guide 20 between the tube holding part 14 and the joint holding part 16 in a state where the tube holding part 14 is not moved (the state shown in FIG. 3A). The When the tube holding part 14 moves by a predetermined distance, the switching valve 30c has a base member 22, more specifically, one of the vertical parts 22b of the base member 22 on the side orthogonal to the moving direction of the tube holding part 14. It is installed at a position where the switch 30d is turned on by the wall surface.

図４はチューブ保持部の移動位置を検知する様子を説明するための説明図である。   FIG. 4 is an explanatory diagram for explaining how the movement position of the tube holding portion is detected.

図４（ａ）に示すように、チューブ保持部１４の移動位置がまだ所定位置に達していない状況においては切替バルブ３０ｃはチューブ保持部１４と継ぎ手保持部１６との間にあり、切替バルブ３０ｃのスイッチ３０ｄはオフの状態である。よって、チューブｔの内部にエアは供給されない。   As shown in FIG. 4A, in a situation where the moving position of the tube holding portion 14 has not yet reached the predetermined position, the switching valve 30c is located between the tube holding portion 14 and the joint holding portion 16, and the switching valve 30c. The switch 30d is off. Therefore, air is not supplied into the tube t.

しかし、チューブ保持部１４が所定距離移動して所定位置に達すると、図４（ｂ）に示すように、スイッチ３０ｄがオンして切替バルブ３０ｃが開弁し、エアの供給が開始される。   However, when the tube holding part 14 moves a predetermined distance and reaches a predetermined position, as shown in FIG. 4B, the switch 30d is turned on, the switching valve 30c is opened, and the supply of air is started.

スイッチ３０ｄは、チューブ保持部１４の台部材２２の垂直部２２ｂの一方の壁面が接触することでオンされるが、具体的には、垂直部２２ｂの一方の壁面には、スイッチ３０ｄをオンするための、スイッチ３０ｄ側に台形状に突出した凸状ガイド２２ｄが設けられる。   The switch 30d is turned on when one wall surface of the vertical portion 22b of the base member 22 of the tube holding portion 14 comes into contact. Specifically, the switch 30d is turned on to one wall surface of the vertical portion 22b. Therefore, a convex guide 22d protruding in a trapezoidal shape is provided on the switch 30d side.

台形状の凸状ガイド２２ｄは、下底に相当する部分が垂直部２２ｂの壁面に取り付けられ、上底に相当する部分がスイッチ３０ｄに接触する。従って、チューブ保持部１４が所定距離移動すると、スイッチ３０ｄは、先ず凸状ガイド２２ｄの一方の脚に相当する部分に接触し、次いで、上底に相当する部分でしばらくオンされた後、他方の脚に相当する部分に接触しながらオフになり、凸状ガイド２２ｄから離れていく。   In the trapezoidal convex guide 22d, a portion corresponding to the lower bottom is attached to the wall surface of the vertical portion 22b, and a portion corresponding to the upper bottom contacts the switch 30d. Accordingly, when the tube holding portion 14 moves by a predetermined distance, the switch 30d first comes into contact with a portion corresponding to one leg of the convex guide 22d, and then is turned on for a while at a portion corresponding to the upper bottom, It turns off while contacting the portion corresponding to the leg, and moves away from the convex guide 22d.

従って、凸状ガイド２２ｄを取り付ける位置と凸状ガイド２２ｄの上底に相当する部分の長さを調整することによってスイッチ３０ｄがオンする位置やオンしている時間、換言すると、エアの供給を開始する位置やエアの供給を行う時間を調整することができる。   Therefore, by adjusting the position where the convex guide 22d is attached and the length of the portion corresponding to the upper base of the convex guide 22d, the position where the switch 30d is turned on and the time during which it is turned on, in other words, the supply of air is started. It is possible to adjust the position to perform and the time for supplying air.

図４（ｃ）では、凸状ガイド２２ｄによってスイッチ３０ｄがオンされているのでまだエアが供給されている状態である。   In FIG. 4C, air is still being supplied because the switch 30d is turned on by the convex guide 22d.

しかし、図４（ｄ）では、チューブ保持部１４がさらに所定距離移動して、スイッチ３０ｄが凸状ガイド２２ｄを通り過ぎたため、スイッチ３０ｄが再びオフしてエアの供給は停止される。   However, in FIG. 4D, the tube holding portion 14 is further moved by a predetermined distance, and the switch 30d passes the convex guide 22d. Therefore, the switch 30d is turned off again, and the supply of air is stopped.

図３の説明に戻ると、図３（ｃ）に示すように、チューブｔには、その内部にエアが供給されているため、チューブｔの内径がエアによって拡径されて、継ぎ手ｃをチューブｔに挿入するのが容易となっている。従って、継ぎ手ｃがチューブｔにスムーズに挿入される。   Returning to the description of FIG. 3, as shown in FIG. 3C, since air is supplied to the inside of the tube t, the inner diameter of the tube t is expanded by the air, and the joint c is connected to the tube t. It is easy to insert into t. Accordingly, the joint c is smoothly inserted into the tube t.

図３（ｄ）では、継ぎ手ｃがチューブｔに完全に挿入されると共に、切替バルブ３０ｃのスイッチ３０ｄもオフとなるため、エアの供給も停止される。   In FIG. 3D, the joint c is completely inserted into the tube t, and the switch 30d of the switching valve 30c is also turned off, so that the supply of air is also stopped.

上記の如く、この発明の実施例にあっては、チューブｔを保持するチューブ保持部１４と、前記チューブ保持部１４に対向して配置され、前記チューブｔの軸心と同軸上または略同軸上に継ぎ手ｃの軸心が位置するように前記継ぎ手ｃを保持する継ぎ手保持部１６とを備え、前記チューブ保持部１４と前記継ぎ手保持部１６の少なくともいずれかを前記チューブｔの軸方向に移動させて前記チューブｔの一端ｔ２に前記継ぎ手ｃを挿入するようにした継ぎ手挿入治具１０において、前記チューブｔの内部にエアを供給可能なエア供給部３０を備える如く構成した。   As described above, in the embodiment of the present invention, the tube holding portion 14 that holds the tube t and the tube holding portion 14 are disposed so as to be opposed to and coaxial with or substantially coaxial with the axis of the tube t.
