(従来技術)
従来、多針によるミシン繕いを行なうものとして第7図
のものがある。旧記第7図に就いて簡単に説明すると、
多数の送り歯30を固定した歯受アーム81は、ミシン
テーブル32の針板33の下面に沿って幅方向に配設す
るように揺動アーム34J:に直角に固定されていた。(Prior Art) Conventionally, there is a sewing machine shown in FIG. 7 that performs mending using a multi-needle sewing machine. A brief explanation of Figure 7 of the old record is as follows.
A tooth receiving arm 81 to which a large number of feed dogs 30 are fixed is fixed at right angles to the swing arm 34J so as to be disposed in the width direction along the lower surface of the throat plate 33 of the sewing machine table 32.
上記のものにあっては直線的な模様縫いを行なうことは
可能であるが、曲率の小さい模様を縫うことは送り歯及
び歯受アームが固定しているので全く不可能であった。Although it is possible to sew a straight pattern with the above-mentioned sewing machine, it is impossible to sew a pattern with a small curvature because the feed dog and tooth receiver arm are fixed.
また、強いて曲率の大きい曲線縫いを行なう場合は針を
1〜2本に減らしたうえで、被加工布材を手で左右に振
りながら縫うことは行なっていたが、曲線の不揃いが目
立ち、仕上りが悪く曲線縫いによる模様の美しさを著し
く損なったり、作業能率が橋めで悪いなどの不都合があ
った。In addition, when sewing curved lines with a large curvature, the number of needles was reduced to one or two, and the workpiece material was swung from side to side by hand while sewing, but the unevenness of the curves became noticeable and the finish was poor. There were other inconveniences such as poor stitching, which significantly impaired the beauty of the pattern created by curved stitching, and poor work efficiency due to stitching.

左右に傾動できる末広状の拡幅部9aを備えている。In this embodiment, as shown in FIGS. 1 to 6, the feed dog l is provided with a rotation mark in the shaft hole 4 of the tooth receiving arm 8 via a shaft 2 superimposed on the lower part. The shaft hole 4 internally communicates at right angles with a screw hole 5 provided on the side surface of the tooth receiving arm 3, and when the shaft 2 is inserted into the shaft hole 4, it aligns with the annular groove 6 provided in the shaft 2. By screwing a screw 8 having a protrusion 7 into the screw hole 5 and engaging the protrusion 7 with the annular groove 6, the feed dog 1 moves around the shaft 2 into the guide groove described below. 9
The feed teeth 1 are connected to each other so as to be able to swing from side to side within the feed teeth 1, and the feed teeth 1 alternately arrange long tooth rows and short tooth rows. A downward shaft hole 4a is bored in the center of the lower surface of the tooth receiving arm 3, the shaft hole 4a is open in common with the pillow material 11, and the shaft hole 4a has a shaft 2a having a ring groove 12 at its lower end. At the same time, the shaft 28 is rotatably inserted into the shaft hole 10 of the bracket 18, and the snap ring 1°5 is fitted into the ring groove 12 protruding outside the lower end of the shaft hole 10, and then removed. The other end of the bracket 18 is provided with a stopper.
A screw hole 5a, which is fixed to the swing arm B (described later) via a screw 8a, is screwed in common with the swing arm B. Actuation arm 1
Reference numeral 6 denotes a bracket 181 which has an F-shaped side surface, has a large gear 17 at one end, and has a screw hole 5b15b at the top.
, 188 are provided in a protruding manner, and are rotatably supported on a boss 18 fixed to the sewing machine table A via a shaft 2b vertically provided at the bottom thereof, and adjusting screws 14.
14 through naphts 19.19, and by pressing the ends of these adjusting screws 14.14 alternately on the left and right sides against the tooth receiver arm 8 through the pillow material 11, the tooth receiver arm 8 is aligned with the shaft. The hanging material 2a is oscillated back and forth in the horizontal direction to form a curved pattern on the hanging material according to a required curved pattern preset in a computer, which will be described later. The small gear 20 meshes with the large gear 17 and is driven by a servo motor 22 via the output shaft 2a. (omitted)
The servo motor 22 is connected to a computer (not shown) which has a large amount of data of necessary curved patterns in advance. Further, the swing arm B is connected to a normal feed dog drive mechanism F, and swings the swing arm B downward and forward and backward about the pivot G, thereby forming the tooth receiver arm 8 into an elliptical shape. During the continuous movement, the hanging material to be processed is intermittently pressed against the first group of feed dogs of the tooth receiving arm 3 and the lower surface of the presser foot H facing the upper curve of the sewing machine table A in the direction of arrow P. They are connected to transport materials. The throat plate 23 is removably disposed on the seat 24 of the sewing machine table A, and the throat plate 281ζ has a plurality of guide grooves 9 arranged in parallel with groups of ordinary needle holes 25 and at intervals. The extended end of each guide groove 9 is a widened part in which the first group of feed teeth, which move in and out of each guide groove 9 and performs an elliptical movement, can tilt left and right along a curved line 1ζ of a curved pattern. It is equipped with 9a.

ることができる。Now, let us explain the case where a desired curved pattern that has been set in the computer in advance is applied to the workpiece material fed onto the sewing machine table A in the direction of arrow P.
The feed dog drive mechanism F operates together with the needle movement mechanism of the sewing machine to sew the sewing needle onto the workpiece material on the sewing machine table A, and the feed dog 1 is caused by the elliptical rotational movement of the swing arm B. The group moves in and out of each guide groove 9 of the throat plate 28 in the direction of the arrow P, and waits above the upward direction of each feed dog 1 to instantaneously insert the material to be processed between each feed dog 1 and the feed dog 1. The material to be processed is moved in the direction of arrow P by working together with the presser foot H.
transport in the direction. In parallel with this hand movement process, the tooth receiving arm 8 is swung back and forth in the horizontal direction around the axis 2a1 while the sensor Iζ of the servo motor 22 continues to detect that the curved pattern is stitched as set. Continuously create the desired curved pattern on the cloth material. At this time, each feed dog 1 moves from the position of the feed dog 1 shown in FIG. 6 and reaches the widened part 9a at the position 1a shown by the chain line, so it moves to the left or right in the widened part 98 according to the curved pattern. It can perform elliptical movements while tilting.

高めることができる。(1) A plurality of feed dogs are supported on a tooth receiving arm so as to be rotatable left and right about a shaft, and the tooth receiving arm is mounted on a swinging arm of the feed dog drive mechanism horizontally back and forth through the shaft. Since it is supported for free swinging movement, curved patterns can be processed freely, accurately and efficiently regardless of the size of the curvature of the curved pattern. (2) The tooth receiving arm and the operating arm are installed on the swinging arm. Since the tooth receiving arm is linked to the required angle via the adjustment screw on the operating arm, a wide variety of curve patterns can be freely set via the transmission mechanism inside the operating arm and the curve detection sensor. By linking it to a computer, it is possible to make the curves of a curved pattern more accurate and greatly enhance the beauty of the pattern.
