以下、本実施形態の布押さえ装置の作用について説明する。 Hereinafter, the operation of the cloth presser 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及び図６（ａ）に示すように、部材押さえ１３における一対の押さえ腕１３２ａ，１３２ｂの係止部材用押さえ部１４０ａ，１４０ｂを前方に位置させる。この際、固定ネジ３０をゆるめておいて、一対の押さえ腕１３２ａ，１３２ｂの左右方向への調整が可能な状態にしておく。目盛り２５，２６が、部材押さえ１３によって押さえられる係止部材１０２に対向する位置に配置されているので、この目盛り２５，２６を基にして、これから縫い付けられる係止部材１０２の幅に合うように、一対の押さえ腕１３２ａ，１３２ｂの幅方向の位置を調整する。なお、この調整では係止部材１０２のホック１０１が、凹部１４１ａ，１４１ｂによって覆われるようにしなければならない。これにより、ホック１０１が押さえ腕１３２ａ，１３２ｂにぶつかって破損することを防止できる。 First, when the one end 103 of the belt and the locking member 102 are sewn, the operator uses the locking member for the pair of pressing arms 132a and 132b in the member pressing 13 as shown in FIGS. The holding parts 140a and 140b are positioned forward. At this time, the fixing screw 30 is loosened so that the pair of pressing arms 132a and 132b can be adjusted in the left-right direction. Since the scales 25 and 26 are arranged at positions facing the locking member 102 pressed by the member presser 13, the scales 25 and 26 are arranged on the basis of the scales 25 and 26 so as to match the width of the locking member 102 to be sewn. In addition, the position in the width direction of the pair of pressing arms 132a and 132b is adjusted. In this adjustment, the hook 101 of the locking member 102 must be covered with the recesses 141a and 141b. As a result, the hook 101 can be prevented from colliding with and being damaged by the pressing arms 132a and 132b.

また、作業者は図２に示すように第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をベルトの一端部１０３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。 Further, as shown in FIG. 2, the operator removes the second restricting members 716 and 816 from the side guides 5 and 6, and further, the auxiliary pressing portion 96 of the auxiliary pressing 91 can be pressed by the one end 103 of the belt. Move it up. 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の各シリンダロッド３ａ，４ａ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 cylinder rods 3a and 4a of 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の針板に沿わせながら、サイドガイド用シリンダ３，４のシリンダロッド３ａ，４ａ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 at the longest time of the cylinder rods 3a, 4a of the side guide cylinders 3, 4 while keeping the locking member 102 along the needle plate of the case sewing machine 300 from the front. , 6 to enter. 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１３２ａ，１３２ｂの係止部材用押さえ部１４０ａ，１４０ｂ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 until the locking member pressing portions 140a and 140b of the pair of pressing arms 132a and 132b press the distal end portion of the locking member 102. 13 is lowered.

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１３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 13 while the locking member 102 is sandwiched between the pair of side guides 5, 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８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 regulating members 7 and 8 also move horizontally, the side guides 5 and 6 are retracted while the vertical positions of the stoppers 714 and 814 and the first prevention portions 715 and 815 are maintained. To do. 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９及び図６（ｂ）に示すように、部材押さえ１３における一対の押さえ腕１３２ａ，１３２ｂの被係止部材用押さえ部１４３ａ，１４３ｂを前方に位置させる。この際、固定ネジ３０をゆるめておいて、一対の押さえ腕１３２ａ，１３２ｂの左右方向への調整が可能な状態にしておき、目盛り２５，２６を基にして、これから縫い付けられる被係止部材１０６の幅に合うように、一対の押さえ腕１３２ａ，１３２ｂの幅方向の位置を調整する。なお、この調整では被係止部材１０６の係止孔１０５の側方に被係止部材用押さえ部１４３ａ，１４３ｂが位置するように調整する。 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. 9 and FIG. 6B, the operator positions the locked member pressing portions 143a and 143b of the pair of pressing arms 132a and 132b in the member pressing unit 13 forward. At this time, the fixing screw 30 is loosened so that the pair of pressing arms 132a and 132b can be adjusted in the left-right direction, and the locked member to be sewn from the scales 25 and 26 from now on. The position in the width direction of the pair of pressing arms 132a and 132b is adjusted so as to match the width of 106. In this adjustment, the locked member holding portions 143a and 143b are adjusted to be positioned on the side of the locking hole 105 of the locked member 106.

また、作業者は図９に示すように第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。 Further, as shown in FIG. 9, the operator can attach the second restricting members 716 and 816 to the side guides 5 and 6, and can further press the auxiliary pressing portion 96 of the auxiliary pressing 91 on the other end 107 of the belt. Move to position. 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 moves between the pair of side guides 5 and 6 at the longest time of the side guide cylinders 3 and 4 while keeping the locked member 106 along the needle plate of the case sewing machine 300 from the front. Let it enter. 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防止部７１５，８１５及び第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１３２ａ，１３２ｂの係止部材用押さえ部１４３ａ，１４３ｂ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, since the first prevention portions 715 and 815 and the second prevention portions 718 and 818 are in contact with the upper surface of the locked member 106, the locked member 106 is prevented from rising. Based on this operation, the control unit 12 drives the member pressing cylinder 11 until the locking member pressing portions 143a and 143b of the pair of pressing arms 132a and 132b press the distal end portion of the locked member 106. The presser 13 is lowered.

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９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。 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 other end 107 of the belt. As a result, as shown in FIG. 9, 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１０６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１０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は退避する。これにより、くるみ縫いの際の針の上下動に対して、サイドガイド５，６が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 106 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. The side guides 5 and 6 are retracted while the position of is maintained. Thus, the locked member 106 and the other end 107 of the belt can be sewn without the side guides 5 and 6 interfering with the vertical movement of the needle during case sewing.

以上のように、本実施形態の布押さえ装置１によれば、係止部材１０２を押さえる場合には係止部材用押さえ部１４０ａ，１４０ｂ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１４３ａ，１４３ｂ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１３２ａ，１３２ｂ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。 As described above, according to the cloth presser device 1 of the present embodiment, when pressing the locking member 102, the locking member pressing portions 140 a and 140 b are arranged to face the locking member 102, and the locked member 106. When pressing, the body portion 131 of the member presser 13 supports the pair of presser arms 132a and 132b so that the presser portions 143a and 143b for the locked member are arranged to face the locked member 106. Therefore, the locking member 102 and the locked member 106 can be pressed by one type of member pressing 13 without preparing a plurality of types of pressing. 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.

さらに、２つの突起１３６ａ，１３７ａ，１３６ｂ，１３７ｂ、長孔１３４ａ，１３４ｂ及び固定ネジ３０からなる調整手段によって一対の押さえ腕１３２ａ，１３２ｂが左右方向（幅方向）に沿って調整されるので、係止部材１０２若しくは被係止部材１０６の種類により幅が異なっていたとしても、その都度最適な位置に一対の押さえ腕１３２ａ，１３２ｂを調整することができる。これにより、部材押さえ１３を交換しなくても複数サイズの係止部材１０２若しくは被係止部材１０６を押さえることができる。
そして、左右方向に沿って刻まれた目盛り２５，２６が、係止部材１０２若しくは被係止部材１０６に対向する位置に備えられているので、この目盛り２５，２６を目安にして一対の押さえ腕１３２ａ，１３２ｂを調整できる。したがって、一対の押さえ腕１３２ａ，１３２ｂの調整を容易に行うことができる。 Further, since the pair of pressing arms 132a and 132b are adjusted along the left and right direction (width direction) by the adjusting means including the two protrusions 136a, 137a, 136b and 137b, the long holes 134a and 134b and the fixing screw 30, Even if the width differs depending on the type of the stop member 102 or the locked member 106, the pair of pressing arms 132a and 132b can be adjusted to the optimal position each time. As a result, the plurality of sizes of the locking member 102 or the locked member 106 can be pressed without replacing the member presser 13.
Since the graduations 25 and 26 engraved along the left-right direction are provided at positions facing the locking member 102 or the locked member 106, a pair of pressing arms with the graduations 25 and 26 as a guide. 132a and 132b can be adjusted. Therefore, the pair of pressing arms 132a and 132b can be easily adjusted.

なお、本発明は上記実施形態に限らず適宜変更可能であるのは勿論である。
本実施形態では、調整手段が、２つの突起１３６ａ，１３７ａ，１３６ｂ，１３７ｂ、長孔１３４ａ，１３４ｂ及び固定ネジ３０からなる場合を例示して説明したが、一対の押さえ腕１３２ａ，１３２ｂを左右方向に沿って調整できるのであればこれに限定されず、例えば本体部１３１及び一対の押さえ腕１３２ａ，１３２ｂの一方に左右方向に沿う溝を形成し、他方に前記溝に係合する凸部を設ければ、凸部が溝に沿うように案内されるために、一対の押さえ腕１３２ａ，１３２ｂを左右方向に沿って調整することが可能となる。 Of course, the present invention is not limited to the above-described embodiment and can be modified as appropriate.
In the present embodiment, the case where the adjusting means includes the two protrusions 136a, 137a, 136b, 137b, the long holes 134a, 134b, and the fixing screw 30 has been described as an example. For example, a groove extending in the left-right direction is formed on one of the main body 131 and the pair of pressing arms 132a and 132b, and a convex portion that engages with the groove is provided on the other. Then, since the convex portion is guided along the groove, the pair of pressing arms 132a and 132b can be adjusted along the left-right direction.

また、本実施形態では、２つの突起１３６ａ，１３７ａ，１３６ｂ，１３７ｂが本体部１３１の表裏面に一体となるように設けられているが、例えば、２つの突起１３６ａ，１３６ｂに雄ネジを切って、本体部１３１の表裏面にも雌ネジを切っておけば、突起１３６ａ，１３６ｂと本体部１３１との着脱が自在に行えるようになる。こうしておけば本体部１３１の表裏面の一方にのみ突起１３６ａ，１３６ｂを取り付けておいても、その面から突起１３６ａ，１３６ｂを取り外して他方の面に取り付けることが可能となる。 In this embodiment, the two protrusions 136a, 137a, 136b, and 137b are provided so as to be integrated with the front and back surfaces of the main body 131. For example, the male protrusions are cut into the two protrusions 136a and 136b.
