実開昭54ー72966号公報Japanese Utility Model Publication No. 54-72966 特許第2691737号公報Japanese Patent No. 2691737 特開平7ー194870号公報JP-A-7-194870

前記従来の自動縫製装置はいずれも縫い代側の布端をガイドしながらミシン縫いしている。即ち、縫い代の幅が一定になるように被縫製材を自動縫製している。   All of the conventional automatic sewing apparatuses perform sewing on the sewing machine while guiding the cloth end on the sewing margin side. That is, the sewing material is automatically sewn so that the width of the seam allowance is constant.

ところで、被縫製材、例えば、自動車用シートのトリムカバーの如く、表皮材、発泡体製ワディング、ワディングカバーなどの積層体からなる厚みがある被縫製材を多数枚重ねて裁断すると裁断ムラが発生し、所定の外形形状に裁断されないものが存在する。   By the way, when a large number of thick materials made of a laminate such as a skin material, foamed wadding, and wadding cover are cut like a trim cover of a sewing material, for example, an automobile seat, uneven cutting occurs. However, there are some which are not cut into a predetermined outer shape.

従って、被縫製材が所定の外形形状に対して大きく裁断されている場合には、前述の如く、縫い代が一定になるように縫製しているため、完成品の実寸法は大になり、その逆の場合には小になる。   Therefore, when the material to be sewn is largely cut with respect to a predetermined outer shape, since the sewing margin is constant as described above, the actual size of the finished product becomes large. In the opposite case, it becomes small.

そのため、縫製後の完成品に寸法ムラが生じ、所期の設計寸法と異なる不具合が生じている。   Therefore, dimensional unevenness occurs in the finished product after sewing, and a defect different from the intended design dimension occurs.

そこで、本発明は縫製後の完成品の寸法が設計通りになるようにミシンで自動縫製できるようにすることを目的とする。   Therefore, an object of the present invention is to enable automatic sewing with a sewing machine so that the dimensions of a finished product after sewing are as designed.

以上の目的を達成するための本発明に係る自動縫製装置は、一側布端が曲線状に裁断されている被縫製材をその一側布端側を端末より外方に突出させて上面に固定する可動板と、この可動板上の被縫製材をミシン縫いする軌跡に摺動させるガイド基板とを有する自動縫製装置であって、前記可動板上に、前記被縫製材の一側布端に対して反対方向の他側布端側をガイドする基準ガイド部を設けてなる構成である。   In order to achieve the above object, an automatic sewing apparatus according to the present invention has a sewing material whose one side fabric end is cut into a curved shape, and the one side fabric end side protrudes outward from the terminal on the upper surface. An automatic sewing apparatus having a movable plate to be fixed and a guide substrate that slides a material to be sewn on the movable plate along a trajectory for sewing, on one side of the cloth material on the movable plate A reference guide portion that guides the other fabric end side in the opposite direction is provided.

以上の構成により、被縫製材はその外形形状にバラ付きがあっても常に実寸法で管理されて縫製されるため、縫製された完成品は設計通りの寸法になる。   With the above configuration, the material to be sewn is sewn under the control of the actual dimensions even when the outer shape of the material has variations, so that the finished product has the dimensions as designed.

また、前記基準ガイド部を可動上に固定したプレートで形成し、そのミシン針方向の端縁を所定の外形形状の被縫製材の他側布端と合致する形状に形成することにより、被縫製材を可動板上にセットする際、被縫製材の他側布端を基準ガイド部の端縁に突き当たることにより容易にセットできる。   In addition, the reference guide portion is formed of a plate fixed on a movable surface, and the edge in the sewing needle direction is formed into a shape that matches the other side cloth end of the sewing material having a predetermined outer shape, so that sewing is performed. When the material is set on the movable plate, it can be easily set by abutting the other cloth end of the material to be sewn against the edge of the reference guide portion.

本発明によれば外形形状にバラ付きがある被縫製材でも自動的にミシン縫いされて、設計通りに完成品を縫製できる。   According to the present invention, even a material to be sewn that has a variation in its outer shape is automatically sewn in a sewing machine, and a finished product can be sewn as designed.

以下、図面に基づいて、本発明の一実施例を説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図1は本発明に係る自動縫製装置を示し、図中Mは電動ミシン本体、Pは作業者を各々示し、ミシンのテーブル盤3上にはガイド基板2が固定され、このガイド基板2上に可動板1が摺動自在に載置されている。   FIG. 1 shows an automatic sewing apparatus according to the present invention, in which M denotes an electric sewing machine main body, P denotes an operator, and a guide board 2 is fixed on a table board 3 of the sewing machine. The movable plate 1 is slidably mounted.

可動板1の裏面にはガイド基板2に設けた二本のガイド溝20、20に遊嵌合するガイドロール12、12が設けてある。   On the back surface of the movable plate 1, guide rolls 12, 12 that are loosely fitted in two guide grooves 20, 20 provided on the guide substrate 2 are provided.

なお、前記ガイド溝20、20は図2に示す可動板1上に固定した被縫製材5をミシン縫いする軌跡に合致するように設定されている。
また、ガイド基板2の作業者P側の端縁21は作業者が作業し易いように切欠されている。
The guide grooves 20 and 20 are set so as to coincide with a locus for sewing the sewing material 5 fixed on the movable plate 1 shown in FIG.
Further, the edge 21 on the worker P side of the guide substrate 2 is cut away so that the worker can easily work.

以上の可動板1上には基準ガイド部10と被縫製材5を可動板1上に固定する複数のクランプ4、4…とが設けてある。   A plurality of clamps 4, 4... For fixing the reference guide portion 10 and the sewing material 5 on the movable plate 1 are provided on the movable plate 1 described above.

基準ガイド部10は図2に示すようにガイド板1の外端縁11に略沿うように可動板1の中央に設けてあり、この可動板1上に載置して前記クランプ4…で固定した被縫製材5における可動板1の外端縁11よりはみ出す一側布端53の部分が図3鎖線に示すようにミシン縫いされる。   As shown in FIG. 2, the reference guide portion 10 is provided at the center of the movable plate 1 so as to substantially follow the outer edge 11 of the guide plate 1 and is placed on the movable plate 1 and fixed by the clamps 4. The portion of the one side fabric end 53 that protrudes from the outer end edge 11 of the movable plate 1 in the sewing material 5 that has been sewn is sewn as shown by the chain line in FIG.

図示する基準ガイド部10は被縫製材5の厚みと略同一の厚みを有する樹脂製のプレートで、その上面10Cには間隔をあけて、被縫製材5の他側布端52に設けた位置決め切欠部52A、52A…に対応する位置決め線10A、10A…が設けてある。   The reference guide portion 10 shown in the figure is a resin plate having a thickness substantially the same as the thickness of the sewing material 5, and a positioning provided on the other cloth end 52 of the sewing material 5 with an interval on the upper surface 10 </ b> C. Positioning lines 10A, 10A... Corresponding to the notches 52A, 52A.

また、基準ガイド部10の先端には、被縫製材5のミシン縫いする始点51A側の前側布端52′をガイドする曲部10′が延設され、この曲部10′の内側壁10B′に、前記被縫製材5の前側布端52′が突き当たるように形成されている。   Further, a curved portion 10 'for guiding the front cloth end 52' on the start point 51A side of the sewing material 5 to be sewn is extended at the tip of the reference guide portion 10, and the inner wall 10B 'of the curved portion 10' is extended. In addition, the front cloth end 52 ′ of the sewing material 5 is formed so as to abut against it.

また、基準ガイド部10の側壁10Bに、前記被縫製材5の他側布端52が突き当たるように、被縫製材5を可動板1上に、図3に示すように突き当てた後、このクランプ4で被縫製材5を可動板1上に挟持して固定する。   Further, after the material to be sewn 5 is abutted on the movable plate 1 as shown in FIG. 3 so that the other cloth end 52 of the material to be sewn abuts against the side wall 10B of the reference guide part 10, The material 5 to be sewn is clamped and fixed on the movable plate 1 by the clamp 4.

なお、被縫製材5の他側布端52側における外形形状が設定された形状に裁断されていない場合、例えば、他側布端52の一部が基準ガイド部10の側壁10Bと一致せずに、外方に突出している場合には、その突出する他側布端52の一部は、基準ガイド部10の上面10C上にはみ出して載置、固定される。   When the outer shape on the other fabric end 52 side of the sewing material 5 is not cut into a set shape, for example, a part of the other fabric end 52 does not coincide with the side wall 10B of the reference guide portion 10. In addition, when protruding outward, a part of the protruding other fabric end 52 protrudes on the upper surface 10C of the reference guide portion 10 and is mounted and fixed.

また、逆に、被縫製材5の他側布端52の一部が、基準ガイド部10の側壁10Bに突き当たることがないように凹欠して裁断されている場合には、その凹欠個所を無理に基準ガイド部10の側壁10Bに沿うように強制して被縫製材5を可動板1上に固定しないようにする。   On the contrary, when a part of the other fabric end 52 of the sewing material 5 is cut out so as not to hit the side wall 10B of the reference guide portion 10, the recessed portion Is forced to be along the side wall 10 </ b> B of the reference guide portion 10 so that the sewing material 5 is not fixed on the movable plate 1.

即ち、被縫製材5はその他側布端52の一部が設計通りに裁断されていない場合、その一部を基準ガイド部10の側壁10Bに突き当たることはないように、被縫製材5を可動板11上にセットする。設計通りに裁断されている大部分を側壁10Bに突き当ててセットする。   In other words, when a part of the other side fabric end 52 is not cut as designed, the sewing material 5 is movable so that a part of the sewing material 5 does not hit the side wall 10B of the reference guide portion 10. Set on the plate 11. Most of the cut as designed is abutted against the side wall 10B and set.

従って、図4に示すように、被縫製材5の他側布端52側の縫い代W2と被縫製材5の実寸法Wとを加えた長さ分に、ミシン針32でミシン縫いされるように、前記可動板1及び基準ガイド10は設定されている。   Therefore, as shown in FIG. 4, the sewing machine needle 32 is used to sew the sewing machine 5 to the length obtained by adding the seam allowance W2 on the other cloth end 52 side of the sewing material 5 and the actual dimension W of the sewing material 5. Further, the movable plate 1 and the reference guide 10 are set.

そのため、例えば、被縫製材5の外形形状にバラ付があった場合、図4に示す被縫製材5の実寸法が一定に管理されるため、ミシン縫いされる一側布端53側の縫い代W1はバラ付く。   Therefore, for example, when the outer shape of the material to be sewn 5 is uneven, the actual dimension of the material to be sewn 5 shown in FIG. W1 will be loose.

前述の如く、被縫製材5の実寸法Wを管理することにより、この被縫製材5に別の被縫製材6を縫合して、自動車用シートのシートバック用トリムカバーなどの完成品を縫製した場合には、設計通りの完成品が形成される。   As described above, by managing the actual dimension W of the sewing material 5, another sewing material 6 is sewn to the sewing material 5 and a finished product such as a seat back trim cover for an automobile seat is sewn. In this case, a finished product as designed is formed.

なお、前記被縫製材5、6は自動車用シートのトリムカバーに使用される表皮、発泡体製ワディング、ワディングカバーの積層体である。また、図4において、50、51はミシン縫いするミシン線を示す。   The sewing materials 5 and 6 are laminates of a skin, foamed padding and a wadding cover used for a trim cover of an automobile seat. In FIG. 4, reference numerals 50 and 51 denote sewing lines for sewing.

図3鎖線に示すように、前記被縫製材5にミシン線51でミシン縫いする被縫製材6はその布端63を作業者Pがミシンのテーブル盤3上に起立固定した縫い代ガイド片30に突き当て乍らミシン縫いする。図2において、図中61はミシン線51で被縫製材5に縫い合わせる被縫製材6のミシン線を示す。   As shown by a chain line in FIG. 3, the sewing material 6 to be sewn to the sewing material 5 by the sewing line 51 is attached to a sewing margin guide piece 30 whose fabric end 63 is fixed upright on the table 3 of the sewing machine by an operator P. The sewing machine is sewn on the end. In FIG. 2, reference numeral 61 in the drawing indicates a sewing line of the sewing material 6 that is sewn to the sewing material 5 by the sewing line 51.

以上の図示する基準ガイド部10は、一定の厚みのプレートで形成しているが、可動板1上に直接設計通りの被縫製材5の他側布端52を表示する表示線を描いたり、型押しても良い。   The reference guide 10 shown in the figure is formed of a plate having a constant thickness, but a display line for displaying the other fabric end 52 of the sewing material 5 as designed directly on the movable plate 1 may be drawn. It may be embossed.

以上のように構成した自動縫製装置に縫製作業を行うには、まず、ガイド基板2上の可動板1を図1に示すように縫合開始位置に移動させて、前述の如く被縫製材5をその他側布端52を基準ガイド部10の側壁10Bに突き当て、被縫製材5の前側布端52′を基準ガイド部10の曲部10′、内側壁10B′に突き当てる。   In order to perform a sewing operation on the automatic sewing apparatus configured as described above, first, the movable plate 1 on the guide substrate 2 is moved to the sewing start position as shown in FIG. The other side fabric end 52 is abutted against the side wall 10B of the reference guide portion 10, and the front side fabric end 52 'of the sewing material 5 is abutted against the curved portion 10' and the inner side wall 10B 'of the reference guide portion 10.

次に多数のクランプ4…で被縫製材5の他側布端52側を可動板1上に挟持して固定する。これにより、被縫製材5は可動板1上にセットされる。
これにより、被縫製材5の一側布端53側が可動板1より外方に突出する。
Next, the other cloth end 52 side of the sewing material 5 is sandwiched and fixed on the movable plate 1 by a number of clamps 4. As a result, the sewing material 5 is set on the movable plate 1.
Thereby, the one-side cloth end 53 side of the sewing material 5 protrudes outward from the movable plate 1.

然る後、作業者Pが別の被縫製材6を持ち、その布端63の先端を縫い代ガイド30に当てる。
このような状態から電動ミシンMを作動させると、押さえ金31が被縫製材6、5を押圧してミシン針32による縫い合わせが開始され、被縫製材5は始点からその上に重ね合わせた被縫製材6と共に、送り歯による被縫製材5、6の送り作動に伴って前方に送り出される。
Thereafter, the operator P holds another material to be sewn 6 and touches the leading end of the cloth end 63 against the sewing allowance guide 30.
When the electric sewing machine M is operated from such a state, the presser foot 31 presses the sewing materials 6 and 5 to start sewing by the sewing needle 32, and the sewing material 5 is overlapped on the sewing material 5 from the starting point. Along with the sewing material 6, it is fed forward along with the feed operation of the sewing materials 5, 6 by the feed dog.

以上の送り作動によって可動板1は自動的にミシン縫いする軌跡に沿って摺動するため、被縫製材5はミシン線51に沿って被縫製材6にミシン縫いされる。
なお、被縫製材6はその布端63を作業者Pが縫い代ガイド片30にガイドしながらミシン縫いするため、ミシン線61に沿ってミシン縫いされる。
Since the movable plate 1 automatically slides along the locus of sewing by the above feed operation, the sewing material 5 is sewn to the sewing material 6 along the sewing line 51.
The material 6 to be sewn is sewn along the sewing line 61 because the operator P sews the cloth end 63 while guiding the cloth end 63 to the sewing allowance guide piece 30.

そして、このミシン縫いが被縫製材5の終点51Bに位置して縫い合わせが完了すると、電動ミシンMは自動的に停止するように構成されている。   When the sewing machine is positioned at the end point 51B of the sewing material 5 and the sewing is completed, the electric sewing machine M is configured to automatically stop.

以上の如くの自動縫製装置によって被縫製材5を自動的にミシン縫いすると、被縫製材5の実寸法Wが一定に縫い合わせができ、被縫製材5の外形形状、例えば、前記一側布端53と他側布端52との間隔が設計寸法に対して広かったり、或いは狭い場合にも実寸法Wは一定に確保される。   When the sewing material 5 is automatically sewn by the automatic sewing apparatus as described above, the actual dimension W of the sewing material 5 can be sewn to a constant value, and the outer shape of the sewing material 5, for example, the one side cloth end Even when the distance between the fabric 53 and the other side fabric end 52 is wider or narrower than the design dimension, the actual dimension W is kept constant.

本発明装置は自動車用シートのトリムカバーの他に、ヘッドレスト、アームレスト、車内の内装品用のトリムカバーなどに利用できる。   The device of the present invention can be used for a headrest, an armrest, a trim cover for interior parts in a vehicle, in addition to a trim cover for an automobile seat.
