従来この種の自動縫製装置はミシンのテーブル盤上に固定したガイド基板又はミシンヘッドに設けたガイド手段によって、被縫製材固定用の可動板をガイドしながら、可動板に固定する被縫製材の布端をミシン縫いしている。   Conventionally, this type of automatic sewing apparatus is used for a sewing material to be fixed to a movable plate while guiding a movable plate for fixing the sewing material by a guide means fixed on a table board of the sewing machine or a guide means provided on a sewing machine head. The fabric edge is sewn on the sewing machine.

そして、前記可動板はミシンのテーブル盤上をミシンの送り歯などの送り作業により被縫製材の布端に沿ってミシン縫いするため、ガイドにより回動しながら、ミシン縫いされる。   The movable plate is sewn on the sewing machine table while being rotated by a guide so as to sew the machine plate along the cloth edge of the material to be sewn by a feeding operation such as a feed dog of the sewing machine.

従って、被縫製材のミシン縫いする布端の始点から終点までの形状が、例えばく字状である場合には、その布端が可動板の端末より縫い代分外方にはみ出すように可動板が形成されている。
そのため、可動板ガイドによって回動しながら、始点から終点までく字状にミシン縫いすると、可動板がミシンの送り作動により、このミシン作業の作業者側まで回動し作業者に接触する。 Therefore, when the shape from the start point to the end point of the cloth end of the sewing material to be sewn is, for example, a square shape, the movable plate is set so that the cloth end protrudes outward from the end of the movable plate by the amount of sewing. Is formed.
For this reason, when the sewing machine is sewn in a square shape from the start point to the end point while being rotated by the movable plate guide, the movable plate is rotated to the operator side of the sewing work by the feed operation of the sewing machine and comes into contact with the operator.

斯る不具合を解消するため、可動板の回動範囲に対して広いガイド基板を設けて、可動板が回動時に作業者に接触しないようにしている。   In order to solve such a problem, a wide guide substrate is provided with respect to the rotation range of the movable plate so that the movable plate does not come into contact with the operator during the rotation.

しかし、斯様に大きなガイド基板を設けると、例えば、前記可動板上に固定した被縫製材に、別の被縫製材等を作業者が手でガイドしながらミシン縫いする場合には、ガイド基板の一部が作業者側に張り出すため、作業者とミシン針までの距離が離れ、無理な姿勢で作業者が作業しなければならない欠陥があった。   However, when such a large guide substrate is provided, for example, when a sewing machine is sewn while an operator manually guides another material to be sewn to the material to be sewn fixed on the movable plate. Since a part of the bulge protrudes to the operator side, the distance between the operator and the sewing needle is increased, and there is a defect that the operator has to work in an unreasonable posture.

そこで、本発明は斯様な従来品の欠陥を除去することを目的とする。   Therefore, the present invention aims to eliminate such defects of the conventional product.

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、被縫製材を 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
摺動させると共に縫製作業の作業者側端末を内方に凹欠状に形成して作業用

板は複数の可動片で形成し、前記摺動時にガイド基板より外方に突出する可
動片は上方に折り畳み可能に連結してなることを特徴とする構成である。 In order to achieve the above object, an automatic sewing apparatus according to the present invention includes a movable plate for fixing a material to be sewn on an upper surface and a locus for sewing the material to be sewn on the movable plate.
For sliding work, the operator side terminal for sewing work is formed inwardly in a recessed shape.
And a guide substrate provided with a space, and when the movable plate slides,
An automatic sewing device, a part of which protrudes outward from the guide substrate , wherein the movable
The plate is formed of a plurality of movable pieces, and can protrude outward from the guide substrate during the sliding.
The moving piece is configured to be foldably connected upward.

従って、被縫製材を固定する可動板が、被縫製材の送り歯による送り作動に伴ってガイド基板上を摺動させると、可動板を構成する可動片の一部が被縫製材と共にミシン作業の作業側に突出するように移動するが、その前に、その可動片の一部とその上に固定する被縫製材を内方に折り畳むことにより、作業者に接触することがない。   Therefore, when the movable plate that fixes the material to be sewn slides on the guide substrate in accordance with the feed operation of the material to be sewn, a part of the movable piece that constitutes the movable plate works together with the material to be sewn. However, it does not come into contact with the operator by folding inward a part of the movable piece and the material to be sewn that is fixed on the movable piece.

そして、その折り畳んだ部分は、作業者側より離れる位置において、元の状態である水平状に戻して被縫製材をミシン縫いする。   Then, the folded portion is returned to the original horizontal state at a position away from the operator side, and the sewing material is sewn on the sewing machine.

本発明によれば、被縫製材を固定する可動板が複数の可動片から構成され、各可動片が上方に折り畳み可能に連結されている。従って、ミシン縫い時に、ミシン作業の作業者側方向に突出する部分の可動片とこの可動片に固定されている部分の被縫製材を折り畳むことにより、作業者側への突出を防止できる。   According to the present invention, the movable plate for fixing the sewing material is composed of a plurality of movable pieces, and each movable piece is connected so as to be foldable upward. Therefore, at the time of sewing, the movable piece of the portion protruding in the direction of the operator of the sewing work and the material to be sewn of the portion fixed to the movable piece can be folded to prevent the protrusion to the operator side.

そのため、可動板は作業者にミシン縫い時に接触することがないため、作業者の作業姿勢に悪い影響を与えることがない。   For this reason, the movable plate does not come into contact with the operator at the time of sewing the sewing machine, so that the operator's working posture is not adversely affected.

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

図１はミシンのテーブル盤３上に固定したガイド基板２と、このガイド基板２に摺動自在に設置した可動板１とを示す。   FIG. 1 shows a guide substrate 2 fixed on a table board 3 of a sewing machine and a movable plate 1 slidably installed on the guide substrate 2.

そして、図１は可動板１がミシン縫い開始時の状態を示し、可動板１はガイド基板２に設けた二本のガイド溝２０、２０に沿って、摺動するように構成されている。また、ガイド基板２の作業者Ｐ側端末２１は内方に凹欠状に形成して、作業者用のスペースを設けている。     FIG. 1 shows a state in which the movable plate 1 is started when the sewing machine is started. The movable plate 1 is configured to slide along two guide grooves 20 and 20 provided in the guide substrate 2. Further, the worker P-side terminal 21 of the guide substrate 2 is formed inwardly in a recessed shape to provide a space for the worker.

即ち、可動板１の底面には前記従来例の如く、前記ガイド溝２０、２０内に転動するガイドローラ１２、１２が設けてあり、この各ガイドローラ１２、１２が各ガイド溝２０、２０内をミシンの送り作用によって可動板１が送られると、可動板１上の図２に示す被縫製材５の布端５３が、ミシン縫いする軌跡に摺動するように構成されている。   That is, as in the conventional example, guide rollers 12 and 12 that roll into the guide grooves 20 and 20 are provided on the bottom surface of the movable plate 1, and the guide rollers 12 and 12 correspond to the guide grooves 20 and 20, respectively. When the movable plate 1 is fed by the feed action of the sewing machine, the cloth end 53 of the sewing material 5 shown in FIG. 2 on the movable plate 1 is slid along the locus for sewing.

図示する可動板１は図２に示すように、三ケの可動片１Ａ、１Ｂ、１Ｃをヒンジ７、７で、上向きに折り畳み又は跳上げ可能に、各々連結されている。   As shown in FIG. 2, the movable plate 1 shown in the figure is connected to three movable pieces 1 </ b> A, 1 </ b> B, and 1 </ b> C by hinges 7 and 7 so that they can be folded or raised upward.

そして、可動板１の全体形状は被縫製材５の外形に略相似するプレートで、その上面に設けた複数のクランプ４、４…で被縫製材５を挟持して固定した際に、被縫製材５の布端５３が、可動板１の端縁１１より外方に突出するように形成されている。図中１０は被縫製材５の実寸法を管理するガイドを示す。   The overall shape of the movable plate 1 is a plate that is substantially similar to the outer shape of the material to be sewn 5, and when the material to be sewn 5 is clamped and fixed by a plurality of clamps 4, 4. The cloth end 53 of the material 5 is formed so as to protrude outward from the end edge 11 of the movable plate 1. In the figure, reference numeral 10 denotes a guide for managing the actual dimension of the sewing material 5.

なお、図１において、Ｍはミシン本体、３１はミシンの押え金、３２はミシン針、３０は被縫製材５にミシン針３２でミシン縫いする別の被縫製材６の布端６３をガイドする縫い代ガイド、Ｐは被縫製材６の布端６３を縫い代ガイド３０に、ガイド等する作業者を各々示す。   In FIG. 1, M is a sewing machine body, 31 is a sewing machine presser foot, 32 is a sewing needle, 30 is a sewing machine needle 32, and 30 guides a cloth end 63 of another sewing material 6 to be sewn with the sewing needle 32. A seam allowance guide P denotes an operator who guides the cloth end 63 of the sewing material 6 to the seam allowance guide 30.

以上の可動板１は図１の矢印方向に、ミシンの送り作用によって移動して、図２に示す被縫製材５をミシン線５１に沿ってミシン縫いする。
その際に、別の被縫製材６は作業者Ｐが布端６３を縫い代ガイド３０に突き当てながら、被縫製材５と共にミシン縫いする。図中６１は被縫製材５と共にミシン縫いする被縫製材６のミシン線を示す。 The above-described movable plate 1 moves in the direction of the arrow in FIG. 1 by the feeding action of the sewing machine, and the sewing material 5 shown in FIG. 2 is sewn along the sewing line 51.
At that time, another sewing material 6 is sewn on the sewing machine 5 together with the sewing material 5 while the worker P abuts the cloth edge 63 against the sewing allowance guide 30. In the figure, reference numeral 61 denotes a sewing line of the material 6 to be sewn together with the material 5 to be sewn.

そして、前記可動板１は可動片１Ｂ、１Ｃが図３に示すように、ヒンジ７、７によって上向きに折り畳み又は跳上げ可能に可動片１Ａに連結されている。また、可動片１Ｂ、１Ｃが作業者Ｐ側に移動する直前に、ミシンがセンサーによって自動停止するように構成されている。   The movable plate 1 is connected to the movable piece 1A so that the movable pieces 1B and 1C can be folded or raised upward by hinges 7 and 7, as shown in FIG. Further, the sewing machine is configured to automatically stop by the sensor immediately before the movable pieces 1B and 1C move to the worker P side.

従って、可動板１の一部である可動片１B又は１C又は可動片１B、１ Cの双方が、被方製材５のミシン縫いによって、ガイド基板１に設けた作業 スペース側の作業者側端末２１より外方に突出するが、この突出前に、前述 するが如く、その直前にミシンの駆動が停止する。

Accordingly, both the movable piece 1B or 1C or the movable pieces 1B and 1C, which are a part of the movable plate 1, are sewn on the sewing machine 5 of the workpiece 5 and the worker side terminal 21 on the work space side provided on the guide substrate 1 is provided. Although it protrudes outward, as described above, the driving of the sewing machine stops immediately before this protrusion.

そこで、例えば図４、図５に示すように可動片１Ｂ、１Ｃの双方、又はいずれか一方を折り畳む、又は跳上げる。これにより、可動片１Ｂ、１Ｃ及びこの可動片１Ｂ、１Ｃに固定されている部分の被縫製材５はガイド基板２の端末２１より外方に突出することがない。   Therefore, for example, as shown in FIGS. 4 and 5, both or one of the movable pieces 1B and 1C are folded or jumped up. Thereby, the movable pieces 1B and 1C and the material 5 to be sewn that is fixed to the movable pieces 1B and 1C do not protrude outward from the terminal 21 of the guide substrate 2.

然る後、ミシンを作動させて、被縫製材５、６を布端５３、６３に沿ってミシン縫いする。   Thereafter, the sewing machine is operated to sew the sewing materials 5 and 6 along the cloth edges 53 and 63.

なお、可動片１Ｂ、１Ｃは作業者Ｐの身体に接触した際に、ミシンの送り作用によって自動的に折り畳み、又は跳上げるように構成してもよい。
また、以上の被縫製材５、６は自動車用シートのトリムカバーを構成する表皮、ワディング、ワディングカバーの積層体からなる表皮部材である。 Note that the movable pieces 1B and 1C may be configured to be automatically folded or jumped up by the feed action of the sewing machine when contacting the body of the worker P.
Further, the above-described sewing materials 5 and 6 are skin members made of a laminate of a skin, a wadding, and a wadding cover that constitute a trim cover of an automobile seat.

本発明は自動車用シートのトリムカバーの自動縫製装置の他に、ヘッドレスト、アームレスト、家具などの表皮部材の自動縫製用に利用できる。   INDUSTRIAL APPLICABILITY The present invention can be used for automatic sewing of skin members such as headrests, armrests, and furniture in addition to an automatic sewing device for trim covers of automobile seats.
