ところで、係止部材１０２、被係止部材１０６のサイズは、ブラジャーのサイズや種類などによって様々なものが用意されているが、従来の位置決めガイド装置であっては、いずれの係止部材１０２、被係止部材１０６であっても位置決めできるように用意しなければならなかった。このため、種類やサイズが異なる度にそれぞれ専用の保持板２０２を準備する必要があり、場合によっては新たな保持板の製作から始めなければならず、サイズの変更に迅速に対応できないばかりか、多数の保持板の中から適応したサイズのものを選択する煩わしさや、そのためのミスも発生しやすく、作業効率が低下し、またコストも増大した。
また、位置決め時においても、部材押さえ２０４、布押さえ２０６及び補助押さえ２０７を個別にペダルで操作しなければならず、作業者の負担になっていた。 By the way, various sizes of the locking member 102 and the locked member 106 are prepared depending on the size and type of the brassiere. However, in the conventional positioning guide device, any locking member 102, Even the locked member 106 had to be prepared so that it could be positioned. For this reason, it is necessary to prepare a dedicated holding plate 202 every time the type and size are different. In some cases, it is necessary to start with the production of a new holding plate, and not only can the size change be handled quickly, The troublesomeness of selecting a suitable size from among a large number of holding plates and mistakes for that are likely to occur, resulting in a decrease in work efficiency and an increase in cost.
Also, at the time of positioning, the member presser 204, the cloth presser 206, and the auxiliary presser 207 must be individually operated with pedals, which is a burden on the operator.

本発明の課題は、メカン用補助押さえを省略したとしても係止部材若しくは被係止部材に対する押さえを可能としたり、保持板や布押さえなどの部材を種類やサイズが異なる毎に準備しなくても複数サイズの係止部材若しくは被係止部材の位置決めを可能としたりすることで、位置決め時の操作工程を簡略化し、作業効率を高めることである。 The problem of the present invention is that even if the mecan auxiliary presser is omitted, it is possible to press the locking member or the locked member, or to prepare a member such as a holding plate or a cloth presser every time the type or size is different. In addition, by enabling positioning of a plurality of sizes of locking members or locked members, it is possible to simplify the operation process at the time of positioning and increase work efficiency.

以下、本実施形態の位置決めガイド装置の作用について説明する。 Hereinafter, the operation of the positioning guide device of the present embodiment will be described.

先ず、ベルトの一端部１０３と係止部材１０２とを縫製する場合、作業者は図２に示すように、部材押さえ１３における一対の押さえ腕１３２の係止部材用押さえ部１３３を前方に位置させる。また、作業者は第２規制部材７１６，８１６をサイドガイド５，６から取り外しておき、さらに補助押さえ９１の補助押さえ部９６を係止部材１０２の押さえが可能な位置まで移動させておく。その後、作業者はこれから縫い付けられる係止部材１０２を基に、一対のサイドガイド５，６の間隔及びストッパ７１４，８１４の位置を調整する。 First, when the one end 103 of the belt and the locking member 102 are sewn, as shown in FIG. 2, the operator positions the locking member pressing portions 133 of the pair of pressing arms 132 in the member pressing 13 forward. . Further, the operator removes the second restricting members 716 and 816 from the side guides 5 and 6 and moves the auxiliary pressing portion 96 of the auxiliary pressing 91 to a position where the locking member 102 can be pressed. Thereafter, the operator adjusts the distance between the pair of side guides 5 and 6 and the positions of the stoppers 714 and 814 based on the locking member 102 to be sewn.

一対のサイドガイド５，６の間隔調整時においては、作業者は係止部材１０２の幅に合う目盛り２５，２６の目盛り線上に、第１延出板５１２，６１２の内側面５１４，６１４及び第２延出板５１３，６１３の内側面５１５，６１５が位置するように、サイドガイド用シリンダ３，４を伸縮方向に移動させる。なお、この間隔調整時においてはサイドガイド用シリンダ３，４が最も伸びた状態（最長時）になっている。
一方、ストッパ７１４，８１４の位置調整時においては、作業者は縫製時の係止部材１０２の先端にストッパ７１４，８１４が位置するように第１規制部材７，８を前後方向に移動させる。 At the time of adjusting the distance between the pair of side guides 5 and 6, the operator places the inner side surfaces 514 and 614 of the first extension plates 512 and 612 on the scale lines of the scales 25 and 26 that match the width of the locking member 102. 2 The side guide cylinders 3 and 4 are moved in the telescopic direction so that the inner side surfaces 515 and 615 of the extending plates 513 and 613 are positioned. At the time of adjusting the distance, the side guide cylinders 3 and 4 are in the most extended state (the longest time).
On the other hand, when adjusting the positions of the stoppers 714 and 814, the operator moves the first restricting members 7 and 8 in the front-rear direction so that the stoppers 714 and 814 are positioned at the leading ends of the locking members 102 during sewing.

調整が完了すると、作業者は、係止部材１０２を前方からくるみ縫いミシン３００のミシンベット上の針板に沿わせながら、サイドガイド用シリンダ３，４の最長時における一対のサイドガイド５，６の間に進入させる。ここで、本実施形態の係止部材１０２は、被係止部材１０６の先端から開放部分の付け根までの長さよりも短いために、サイドガイド５，６における第２延出板５１３，６１３の内側面５１５，６１５に当接させながら進入させなくとも、サイドガイド５，６における第１延出板５１２，６１２の内側面５１４，６１４だけに当接させながら進入させることが可能である。この進入時には、係止部材１０２の先端が第１防止部７１５，８１５の下面７１５ａ，８１５ａに当接してから、ストッパ７１４，８１４に当接するので、作業者は係止部材１０２とストッパ７１４，８１４との当接が確認されたら進入を停止させる。これで、係止部材１０２の位置決めが完了する。 When the adjustment is completed, the operator sets the pair of side guides 5 and 6 at the longest time of the side guide cylinders 3 and 4 while keeping the locking member 102 along the needle plate on the sewing bed of the case sewing machine 300 from the front. Let go between. Here, since the locking member 102 of this embodiment is shorter than the length from the front-end | tip of the to-be-latched member 106 to the root of an open part, it is the inside of the 2nd extension plates 513 and 613 in the side guides 5 and 6. Even if the side guides 515 and 615 are not brought into contact with the side surfaces 515 and 615, the side guides 5 and 6 can be brought into contact with only the inner side surfaces 514 and 614 of the first extension plates 512 and 612. At the time of this entry, the front end of the locking member 102 contacts the lower surfaces 715a and 815a of the first prevention portions 715 and 815 and then contacts the stoppers 714 and 814. If contact with is confirmed, the approach is stopped. This completes the positioning of the locking member 102.

係止部材１０２が位置決めされると、作業者は係止部材１０２の開放部分にベルトの一端部１０３を挟んで重ね合わせてから、部材押さえ用スイッチ１４を操作する。この際、第１防止部７１５，８１５は係止部材１０２の上面に当接しているので、係止部材１０２の浮き上がりを防止している。この操作に基づいて制御部１２は、部材押さえ用シリンダ１１を駆動させて、一対の押さえ腕１３２の係止部材用押さえ部１３３が係止部材１０２の先端部を押さえるまで部材押さえ１３を下降させる。 When the locking member 102 is positioned, the operator operates the member pressing switch 14 after placing the one end portion 103 of the belt on the open portion of the locking member 102 so as to overlap. At this time, since the first prevention portions 715 and 815 are in contact with the upper surface of the locking member 102, the locking member 102 is prevented from rising. Based on this operation, the control unit 12 drives the member pressing cylinder 11 to lower the member pressing unit 13 until the locking member pressing unit 133 of the pair of pressing arms 132 presses the distal end portion of the locking member 102. .

そして、作業者は補助押さえ用スイッチ１５を操作する。この操作に基づいて制御部１２は、補助押さえ用シリンダ９２を駆動させて、補助押さえ９１の補助押さえ部９６がベルトの一端部１０３を押さえるまで、回転軸９５を回転させる。これにより、図２に示すように係止部材１０２が一対のサイドガイド５，６に挟まれた状態で、係止部材１０２は部材押さえ１３３に押さえられるとともに、ベルトの一端部１０３は補助押さえ９１におさえられる。 Then, the operator operates the auxiliary pressing switch 15. Based on this operation, the controller 12 drives the auxiliary pressing cylinder 92 to rotate the rotating shaft 95 until the auxiliary pressing portion 96 of the auxiliary pressing 91 presses the one end 103 of the belt. Accordingly, as shown in FIG. 2, the locking member 102 is pressed by the member press 133 while the locking member 102 is sandwiched between the pair of side guides 5 and 6, and the one end 103 of the belt is the auxiliary press 91. It is held down.

このように、係止部材１０２及びベルトの一端部１０３が押さえられて固定されると、縫製を開始するために作業者は縫製開始スイッチ１６を操作する。この操作に基づいて制御部１２は、くるみ縫いミシン３００の主軸モータドライバ３０１及びＸ／Ｙモータドライバ３０２に縫製開始の指示を与えるとともに、サイドガイド用シリンダ３，４のシリンダロッド３ａ，４ａを収縮させる。サイドガイド用シリンダ３，４が収縮されると、この収縮に伴って図５に示すようにサイドガイド５，６が外側へと水平に沿って移動することになる。つまり、第１規制部材７，８も水平に沿って移動するために、ストッパ７１４，８１４及び第１防止部７１５，８１５の垂直方向の位置は維持された状態で、サイドガイド５，６は、サイドガイド５，６が係止部材１０２に当接する当接位置から、隔離した退避位置、すなわち針棒の上下動経路から隔離した位置に退避する。これにより、サイドガイド５，６がくるみ縫いの邪魔になることなく、係止部材１０２及びベルトの一端部１０３を縫製できる。 As described above, when the locking member 102 and the one end 103 of the belt are pressed and fixed, the operator operates the sewing start switch 16 in order to start sewing. Based on this operation, the control unit 12 gives an instruction to start sewing to the spindle motor driver 301 and the X / Y motor driver 302 of the case sewing machine 300, and contracts the cylinder rods 3a, 4a of the side guide cylinders 3, 4. Let When the side guide cylinders 3 and 4 are contracted, the side guides 5 and 6 are moved horizontally along the contraction as shown in FIG. That is, since the first restricting members 7 and 8 also move along the horizontal, the side guides 5 and 6 have the vertical positions of the stoppers 714 and 814 and the first preventing portions 715 and 815 maintained. The side guides 5 and 6 are retracted from the contact position where the side guides 5 and 6 contact the locking member 102 to the isolated retracted position, that is, the position isolated from the vertical movement path of the needle bar. As a result, the locking member 102 and the one end 103 of the belt can be sewn without the side guides 5 and 6 interfering with the case of the case stitch.

次に、ベルトの他端部１０７と被係止部材１０６とを縫製する場合について説明する。この場合、作業者は図６に示すように、部材押さえ１３における一対の押さえ腕１３２の被係止部材用押さえ部１３４を前方に位置させる。また、作業者は第２規制部材７１６，８１６をサイドガイド５，６に取り付けておき、さらに補助押さえ９１の補助押さえ部９６をベルトの他端部１０７の押さえが可能な位置まで移動させておく。その後、作業者はこれから縫い付けられる被係止部材１０６を基に、係止部材１０２の場合と同様の手順で、一対のサイドガイド５，６の間隔及びストッパ７１４，８１４の位置を調整する。 Next, a case where the other end 107 of the belt and the locked member 106 are sewn will be described. In this case, as shown in FIG. 6, the operator positions the to-be-locked member pressing portions 134 of the pair of pressing arms 132 in the member pressing portion 13 in the forward direction. Further, the operator attaches the second restricting members 716 and 816 to the side guides 5 and 6, and further moves the auxiliary pressing portion 96 of the auxiliary pressing portion 91 to a position where the other end portion 107 of the belt can be pressed. . Thereafter, the operator adjusts the distance between the pair of side guides 5 and 6 and the positions of the stoppers 714 and 814 on the basis of the locked member 106 to be sewn in the same procedure as in the case of the locking member 102.

調整が完了すると、作業者は、被係止部材１０６を前方からくるみ縫いミシン３００のミシンベッド上の針板に沿わせながら、サイドガイド用シリンダ３，４の最長時における一対のサイドガイド５，６の間に進入させる。ここで、被係止部材１０６は、サイドガイド５，６における第２延出板５１３，６１３の内側面５１５，６１５及び第１延出板５１２，６１２の内側面５１４，６１４を当接させながら進入させる。この進入時には、係止部材１０２の先端が、第２防止部７１８、８１８の下面７１８ａ，８１８ａに当接してから、第１防止部７１５，８１５の下面７１５ａ，８１５ａに当接し、その後ストッパ７１４，８１４に当接するので、作業者は被係止部材１０６とストッパ７１４，８１４との当接が確認されたら進入を停止させる。これで、被係止部材１０６の位置決めが完了する。 When the adjustment is completed, the operator places the pair of side guides 5 at the longest time of the side guide cylinders 3 and 4 while keeping the locked member 106 along the needle plate on the sewing machine bed of the case sewing machine 300 from the front. Enter between 6. Here, the locked member 106 contacts the inner side surfaces 515 and 615 of the second extension plates 513 and 613 and the inner side surfaces 514 and 614 of the first extension plates 512 and 612 in the side guides 5 and 6. Let it enter. At the time of entering, the front end of the locking member 102 contacts the lower surfaces 718a and 818a of the second prevention portions 718 and 818, then contacts the lower surfaces 715a and 815a of the first prevention portions 715 and 815, and then the stopper 714. Since the abutment comes into contact with 814, the operator stops the entry when the contact between the locked member 106 and the stoppers 714 and 814 is confirmed. This completes the positioning of the locked member 106.

被係止部材１０６が位置決めされると、作業者は被係止部材１０６の開放部分にベルトの他端部１０７を挟んで重ね合わせてから、部材押さえ用スイッチ１４を操作する。この際、第１規制部材７，８の第１防止部７１５，８１５及び第２規制部材７１６，８１６の第２防止部７１８，８１８は、被係止部材１０６の上面に当接しているので、被係止部材１０６の浮き上がりを防止している。この操作に基づいて制御部１２は、部材押さえ用シリンダ１１を駆動させて、一対の押さえ腕１３２の被係止部材用押さえ部１３４が被係止部材１０６の先端部を押さえるまで部材押さえ１３を下降させる。 When the locked member 106 is positioned, the operator operates the member pressing switch 14 after placing the other end 107 of the belt on the open portion of the locked member 106 so as to overlap. At this time, the first prevention portions 715 and 815 of the first restriction members 7 and 8 and the second prevention portions 718 and 818 of the second restriction members 716 and 816 are in contact with the upper surface of the locked member 106. The locked member 106 is prevented from floating. Based on this operation, the control unit 12 drives the member pressing cylinder 11 and holds the member pressing unit 13 until the locked member pressing unit 134 of the pair of pressing arms 132 presses the distal end portion of the locked member 106. Lower.

その後、作業者は、補助押さえ用スイッチ１５を操作する。この操作に基づいて制御部１２は、補助押さえ用シリンダ９２を駆動させて、補助押さえ９１の補助押さえ部９６がベルトの他端部１０７を押さえるまで、回転軸９５を回転させる。これにより、図６に示すように被係止部材１０６が一対のサイドガイド５，６に挟まれた状態で、被係止部材１０６は部材押さえ１３３に押さえられるとともに、ベルトの他端部１０７は補助押さえ９１におさえられる。 Thereafter, the operator operates the auxiliary pressing switch 15. Based on this operation, the controller 12 drives the auxiliary pressing cylinder 92 to rotate the rotating shaft 95 until the auxiliary pressing portion 96 of the auxiliary pressing 91 presses the other end 107 of the belt. As a result, as shown in FIG. 6, the locked member 106 is pressed by the member press 133 while the locked member 106 is sandwiched between the pair of side guides 5 and 6, and the other end 107 of the belt is It is held by the auxiliary presser 91.

このように、被係止部材１０３及びベルトの他端部１０７が押さえられて固定されると、縫製を開始するために作業者は縫製開始スイッチ１６を操作する。この操作に基づいて制御部１２は、くるみ縫いミシン３００の主軸モータドライバ３０１及びＸ／Ｙモータドライバ３０２に縫製開始の指示を与えるとともに、サイドガイド用シリンダ３，４を収縮させる。サイドガイド用シリンダ３，４が収縮されると、この収縮に伴って図７に示すようにサイドガイド５，６が外側へと移動することになる。つまり、第１規制部材７，８及び第２規制部材７１６，８１６も水平に沿って移動するために、ストッパ７１４，８１４、第１防止部７１５，８１５及び第２防止部７１８，８１８の垂直方向の位置は維持された状態で、サイドガイド５，６は、サイドガイド５，６が被係止部材１０６に当接する当接位置から、隔離した退避位置、すなわち針棒の上下動経路から隔離した位置に退避する。これにより、サイドガイド５，６がくるみ縫いの邪魔になることなく、被係止部材１０６及びベルトの他端部１０７を縫製できる。 Thus, when the locked member 103 and the other end 107 of the belt are pressed and fixed, the operator operates the sewing start switch 16 in order to start sewing. Based on this operation, the control unit 12 gives an instruction to start sewing to the spindle motor driver 301 and the X / Y motor driver 302 of the case sewing machine 300 and contracts the side guide cylinders 3 and 4. When the side guide cylinders 3 and 4 are contracted, the side guides 5 and 6 are moved outward as shown in FIG. That is, since the first restricting members 7 and 8 and the second restricting members 716 and 816 also move horizontally, the vertical direction of the stoppers 714 and 814, the first preventing portions 715 and 815, and the second preventing portions 718 and 818. In this state, the side guides 5 and 6 are separated from the contact position where the side guides 5 and 6 are in contact with the locked member 106, away from the retracted position, that is, the vertical movement path of the needle bar. Retreat to position. Thereby, the to-be-latched member 106 and the other end portion 107 of the belt can be sewn without the side guides 5 and 6 interfering with the case of the case stitch.

以上のように、本実施形態の位置決めガイド装置１によれば、一対のサイドガイド５，６が係止部材１０２若しくは被係止部材１０６の両側面に当接することで、係止部材１０２若しくは被係止部材１０６の幅方向へのズレを規制している。また、サイドガイド５，６に備えられたストッパ７１４，８１４が、サイドガイド５，６に挟まれた係止部材１０２若しくは被係止部材１０６の先端面に当接することで、係止部材１０２若しくは被係止部材１０６の先方へのズレを規制している。これにより、係止部材１０２若しくは被係止部材１０６の水平方向の位置決めが行われることになる。そして、第１防止部７１５，８１５が、サイドガイド５，６に挟まれた係止部材１０２若しくは被係止部材１０６の先端上面に当接することで、係止部材１０２若しくは被係止部材１０６を押さえ、浮き上がることを防止している。また、浮き上がり防止部としての第２防止部７１８，８１８はサイドガイド５，６に挟まれた被係止部材１０６の上面に当接することで、浮き上がりを防止している。ここで、浮き上がり防止部は垂直方向の位置を維持した所定の高さで被係止部材１０６の上面に当接しているので、浮き上がり防止部を昇降させなくとも、被係止部材１０６の浮き上がりを防止することができる。つまり、従来のメカン用補助押さえのような昇降動作を省略したとしても被係止部材１０６に対する押さえが可能となるために、この昇降動作に対応する操作工程を省略できる。したがって、位置決め時の操作工程が簡略化されて、作業効率が高められる。 As described above, according to the positioning guide device 1 of the present embodiment, the pair of side guides 5 and 6 are brought into contact with both side surfaces of the locking member 102 or the locked member 106, thereby The shift of the locking member 106 in the width direction is restricted. Further, the stoppers 714 and 814 provided on the side guides 5 and 6 come into contact with the locking member 102 or the front end surface of the locked member 106 sandwiched between the side guides 5 and 6, so that the locking member 102 or The forward displacement of the locked member 106 is restricted. As a result, the locking member 102 or the locked member 106 is positioned in the horizontal direction. And the 1st prevention part 715,815 contacts the locking member 102 or the to-be-locked member 106 pinched | interposed into the side guides 5 and 6, and the locking member 102 or the to-be-latched member 106 is made to contact. Holds and prevents floating. Further, the second preventing portions 718 and 818 as the lifting preventing portions are in contact with the upper surface of the locked member 106 sandwiched between the side guides 5 and 6 to prevent the lifting. Here, since the lifting prevention portion is in contact with the upper surface of the locked member 106 at a predetermined height that maintains the vertical position, the lifting of the locked member 106 is prevented without raising or lowering the lifting prevention portion. Can be prevented. That is, even if the lifting / lowering operation such as the conventional auxiliary pressing for mecan is omitted, the pressed member 106 can be pressed, so that the operation process corresponding to the lifting / lowering operation can be omitted. Therefore, the operation process at the time of positioning is simplified and work efficiency is improved.

また、浮き上がり防止部が第２防止部７１８，８１８によって被係止部材１０６の少なくとも両側で当接するので、被係止部材１０６の浮き上がりをより確実に防止することができる。
ここで、第１防止部７１５、８１５は、係止部材１０２若しくは被係止部材１０６の先端上面に当接するので、浮き上がり量が最も大きくなると想定される係止部材１０２若しくは被係止部材１０６の先端を押さえることができる。また、第２防止部７１８，８１８は、被係止部材１０６における開放部分の付け根近傍に当接するので、開放部分でベルトの他端部１０７を挟むときにスムーズに開放部分を開くことができる。 In addition, since the floating prevention portion abuts on at least both sides of the locked member 106 by the second prevention portions 718 and 818, the floating of the locked member 106 can be more reliably prevented.
Here, since the first prevention portions 715 and 815 are in contact with the top surface of the front end of the locking member 102 or the locked member 106, the amount of lifting is assumed to be the largest. You can hold the tip. Further, since the second prevention portions 718 and 818 are in contact with the vicinity of the root of the open portion of the locked member 106, the open portion can be smoothly opened when the other end portion 107 of the belt is sandwiched between the open portions.

そして、第１防止部７１５，８１５の下面７１５ａ，８１５ａ及び第２防止部７１８，８１８の下面７１８ａ，８１８ａは、係止部材１０２若しくは被係止部材１０６の先端側に位置する部分が基端側に位置する部分よりも低くなるように傾いているので、一対のサイドガイド５，６の間に係止部材１０２若しくは被係止部材１０６を進入させる際に、先端部が僅かに反っていたとしても、これら下面７１５ａ，７１８ａ，８１５ａ，８１８ａの傾きによって反りが矯正されることになる。このため、反りによって引っかかることなどが抑制され、結果係止部材１０２若しくは被係止部材１０６の進入作業がスムーズに行われることになる。
また、第２防止部７１８，８１８が、斜め上方に延出しているので、被係止部材１０６の先端側に位置する部分を容易に開放部分を開くことができる。 The lower surfaces 715a and 815a of the first prevention portions 715 and 815 and the lower surfaces 718a and 818a of the second prevention portions 718 and 818 are located on the proximal end side of the portion located on the distal end side of the locking member 102 or the locked member 106. The tip part is slightly warped when the locking member 102 or the locked member 106 is inserted between the pair of side guides 5 and 6 because it is inclined to be lower than the portion located at Also, the warpage is corrected by the inclination of the lower surfaces 715a, 718a, 815a, and 818a. For this reason, it is suppressed that it gets caught by the warp, and as a result, the entry operation of the locking member 102 or the locked member 106 is performed smoothly.
Moreover, since the 2nd prevention parts 718 and 818 are extended diagonally upward, the part located in the front end side of the to-be-latched member 106 can be easily opened.

また、ネジ止め部７１，８１及びネジ７２，８２によって、ストッパ７１４，８１４が係止部材１０２若しくは被係止部材１０６の進入方向（前後方向）に沿って移動自在であるので、ストッパ７１４，８１４の位置を調整することができる。これにより、係止部材１０２若しくは被係止部材１０６の長さが異なったとしてもストッパ７１４，８１４の位置を調整すれば先方へのズレを規制できる。これにより、第１規制部材７，８を交換しなくとも、複数サイズの係止部材１０２若しくは被係止部材１０６の位置決めが可能となり、作業効率を高めることである。
そして、係止部材１０２若しくは被係止部材１０６の両側面への当接時における一対のサイドガイド５，６の間隔が、サイドガイド用シリンダ３，４を固定する固定部３１，４１によって調整自在であるので、係止部材１０２若しくは被係止部材１０６の幅が異なったとしても一対のサイドガイド５，６の間隔を調整すれば幅方向へのズレを規制できる。これにより、一対のサイドガイド５，６を交換しなくとも、複数サイズの係止部材１０２若しくは被係止部材１０６の位置決めが可能となり、作業効率を高めることである。
そして、サイドガイド５，６、第１規制部材７，８及び第２規制部材７１６，８１６が一体的に設けられているので、サイドガイド用シリンダ３，４のように、駆動源が１つであってもこれらを連動させることができる。 Further, the stoppers 714 and 814 are movable along the entering direction (front-rear direction) of the locking member 102 or the locked member 106 by the screw fixing portions 71 and 81 and the screws 72 and 82. Can be adjusted. Thereby, even if the length of the locking member 102 or the locked member 106 is different, the displacement to the front can be restricted by adjusting the positions of the stoppers 714 and 814. This makes it possible to position the plurality of sizes of the locking members 102 or the locked members 106 without exchanging the first restricting members 7 and 8, thereby improving work efficiency.
And the space | interval of a pair of side guides 5 and 6 at the time of contact | abutting to the both sides | surfaces of the latching member 102 or the to-be-latched member 106 is adjustable by the fixing | fixed part 31 and 41 which fixes the cylinders 3 and 4 for side guides. Therefore, even if the width of the locking member 102 or the locked member 106 is different, the shift in the width direction can be restricted by adjusting the distance between the pair of side guides 5 and 6. This makes it possible to position a plurality of sizes of the locking members 102 or the locked members 106 without exchanging the pair of side guides 5 and 6, thereby improving work efficiency.
Since the side guides 5 and 6, the first restricting members 7 and 8 and the second restricting members 716 and 816 are integrally provided, one drive source is provided like the side guide cylinders 3 and 4. Even if they exist, they can be linked.

また、係止部材１０２を押さえる場合には係止部材用押さえ部１３３が係止部材１０２に対向配置され、被係止部材１０６を押さえる場合には被係止部材用押さえ部１３４が被係止部材１０６に対向配置されるように、部材押さえ１３の本体部１３１が一対の押さえ腕１３２を切り替え自在に支持しているので、複数種類の押さえを準備しなくても、一種類の部材押さえ１３によって係止部材１０２及び被係止部材１０６を押さえることができる。このように複数種類の押さえの準備や選択が不要になれば、準備作業が簡略化されて作業効率を高めることができる。さらに、多数の部材押さえを準備するためのコストも低減できる。 Further, when pressing the locking member 102, the locking member pressing portion 133 is disposed opposite to the locking member 102, and when pressing the locked member 106, the locked member pressing portion 134 is locked. Since the main body 131 of the member presser 13 supports the pair of presser arms 132 so as to be opposed to the member 106, one type of member presser 13 can be used without preparing a plurality of types of pressers. Thus, the locking member 102 and the locked member 106 can be pressed. Thus, if preparation and selection of a plurality of types of pressers are not required, preparation work can be simplified and work efficiency can be improved. Furthermore, the cost for preparing a large number of member presses can be reduced.

なお、本発明は上記実施の形態に限らず適宜変更可能であるのは勿論である。
例えば、本実施形態では、サイドガイド用シリンダ３，４のシリンダロッド３ａ，４ａ移動させることで、一対のサイドガイド５，６の間隔調整を行っていたが、サイドガイド用シリンダ３，４の伸縮量を制御し最長時におけるサイドガイド５，６の位置を異ならせることで、サイドガイド５，６の間隔調整を行うことも可能である。 It is needless to say that the present invention is not limited to the above embodiment and can be modified as appropriate.
For example, in this embodiment, the distance between the pair of side guides 5 and 6 is adjusted by moving the cylinder rods 3 a and 4 a of the side guide cylinders 3 and 4. It is also possible to adjust the distance between the side guides 5 and 6 by controlling the amount and changing the positions of the side guides 5 and 6 at the longest time.
