Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案はミシンの糸払い装置に関するもので、特に
全体を作業者の布扱いの妨げとならない位置に配置する
と共に部品点数が少なく全体をコンパクトにして製作容
易な糸払い装置を案出したものである。[Detailed description of the invention] [Industrial application field] This invention relates to a thread wiping device for a sewing machine. Thus, a yarn wiper that is easy to manufacture has been devised.
〔従来の技術〕 従来この種の装置としてあご部下方に配置しソレノイ
ドに連動する4節リンクを配してワイパーを駆動する例
えば実開昭60-143579号公報に示されたものが知られて
いる。これら糸払い装置は布の送り出し側に4節リンク
が空間スペースを占めているため、布扱いの妨げとなる
欠点があった。[Prior Art] Conventionally, as this type of device, a device disclosed in Japanese Utility Model Application Laid-Open No. 60-143579 is known in which a wiper is driven by arranging a four-bar link that is arranged below a jaw portion and interlocks with a solenoid. I have. These thread wipers have a drawback that the handling of the cloth is hindered because the four-node link occupies a space on the cloth sending side.
またソレノイドの励磁状態になったとき、ワイパーが
針糸を係止する位置まで移動しその後ソレノイドの非励
磁に伴いばね等の復元弾性力により元位置迄復帰する間

針糸が次の継目のためかま,天秤等により緊張しこれに
よりワイパーが上下動する針の軌跡内に針糸により引き
寄せられ衝突損傷し、ときには損傷破片が飛び散り目に
入る恐れがある等の大きな安全上の欠点があった。When the solenoid is excited, the wiper moves to the position where the needle thread is locked, and then returns to the original position due to the restoring elastic force of a spring or the like due to the non-excitation of the solenoid, and the needle thread is removed from the work. Since the needle thread is pulled out, the needle thread cannot be removed at the time of sewing a thick material with a restoring elastic force of a spring or the like.
There was also a disadvantage. Further, when the sewing machine cannot be completely removed, that is, when the wiper does not return to the original return position while hooking the needle thread, or when the sewing machine is restarted by mistake,
The needle thread is tensioned by a hook, a balance, etc. for the next seam, and as a result, the wiper is pulled by the needle thread into the trajectory of the needle that moves up and down, causing collision damage, and sometimes there is a possibility that damaged debris may fly into the eye. There were safety shortcomings.
これらを解消するものとして、例えば実公昭61-7664
号公報に示されたものがあるが、これらにおいては、布
の送り出し側空間に揺動リンクが露出して配置されてい

ン,部品点数も多く全体が複雑になりコスト高,修理上
めんどうなどの欠点があった。As a solution to these problems, for example, Japanese Utility Model Publication No. 61-7664
However, in these, the swing links are exposed and arranged in the space on the sending-out side of the cloth. However, there were drawbacks such as damage to the oscillating link, insufficient feeding of the cloth, and no operation of the wiper. In addition, there are drawbacks such as swinging links and links hitting the hands and fingers of the worker on the cloth sending side, and the number of various links, pins and parts is large and the whole becomes complicated, resulting in high cost, repair and trouble. There were drawbacks.
更には揺動リンクを案内する支持体の案内部が針板か
らの高さが低い位置にあり、かつ布押えに接近し布押え
棒を挟んで対向配置されているので布の着脱時の押え上
昇量が充分とれない欠点もあった。Further, since the guide portion of the supporting member for guiding the swing link is located at a position lower than the needle plate and close to the cloth presser and opposed to the cloth presser bar, the presser foot when attaching and removing the cloth There was also a disadvantage that the amount of rise was not sufficient.
更には各種縫製作業に対応して各種の布押えに交換す
る際、布押さえの交換作業が困難である等の欠点あっ
た。Furthermore, when replacing with various types of presser foot corresponding to various sewing operations, there is a disadvantage that it is difficult to replace the presser foot.

糸払い装置を得る事を目的とする。This invention was made in order to solve the above-mentioned problems, while increasing the pulling force of the needle thread,
The purpose is to obtain a thread wiper that expands the space on the cloth sending side and ensures the operation of the wiper even if the cloth on the sending side accumulates, and is compact in size and easy to manufacture with a minimum number of parts. And

る。Next, the operation of the thread removing device of the sewing machine according to the present invention will be described. FIG. 1 shows a state in which the drive arm (10) is pulled down in a counterclockwise direction by a spring (not shown) built in the solenoid (9), and the guide shaft (20) is moved through a pin (24) and a link (23). ) Is pulled upward as shown in FIG. This makes long grooves (14L) and (14R) and guide grooves (15L) and (15R)
The movable body (18), which is loosely fitted and guided, is pulled up as shown in FIG. 1 and the shaft (19) is in contact with the uppermost portion of the long grooves (14L) and (14R), and the guide groove is provided. (20) is located at the uppermost part of the guide grooves (15L) and (15R). In this state, the tip of the wiper (26) is above the presser foot (8),
It is in a position where it does not hinder the presser foot (8) that moves up and down due to a knee operation or the like of the operator. After the sewing operation is completed, the needle thread (28) is cut below the needle plate (5) by a thread cutting device (not shown), and when the needles (3L) (3R) stop near the top dead center, the solenoid (9) is turned off. ) Is excited and the drive arm (1
1) rotates clockwise as shown in FIG. 1 to FIG. 3, whereby the link (23) moves downward, and the moving body (18) is moved via the guide shaft (20) into the guide groove (15L). , (15R), while being guided and restricted by the straight grooves (16L) and (16R) and the long grooves (14L) and (14R), the shaft (19) is tilted obliquely to the lowermost end of the long grooves (14L) and (14R). It moves as shown in FIG. Thereby, the tip of the wiper (26) comes from the position above the presser foot (8) shown in FIG. 1 to a position where the needle thread (28) can be locked as shown in FIG. The solenoid (9) is in the energized state further, and the drive arm (10) further rotates clockwise from FIG. 3 to FIG. Since the shaft (19) is in contact with the lowermost end of the long groove (14L) (14R), the counterclockwise rotation of the drive arm (10) following FIG. 3 causes the guide shaft (20) via the link (23). ) Is guided by the circular grooves (17L) and (17R) of the guide grooves (15L) and (15R), while the moving body (18) is in contact with the lower end of the grooves (14L) and (14R). Is rotated counterclockwise about the fulcrum. For this reason, the wiper (26) holds the needle (3) with the needle thread (28) locked.
L) and (3R) are passed near the tip, and the needle thread (28) is lifted vertically upward with respect to the bed surface where it is easy to pull out. As a result, the end of the needle thread (28) comes out of the upper surface of the work clamp (8).

0) rotates counterclockwise, which causes the link (23)
Is pulled back, so that the guide shaft (20) is
The moving body (18) is pulled up along the circular arc grooves (17L) and (17R) of (L) and (15R), and the moving body (18) rotates clockwise about the shaft (19) as a fulcrum, and is in a state shown in FIG. Further, the drive arm (10) is rotated counterclockwise by a spring built in the solenoid, and returns to the original position shown in FIG. Along with this, the wiper (26) also returns to the position above the presser foot (8) in the original state shown in FIG. 1 and raises and lowers the presser foot (8) by the knee operation of the operator in order to attach and detach the cloth (6). And return to a position that does not interfere. Even if the cloth (6) accumulates in the space (29), the cloth (6) first hits the fixed supports (13L) and (13R) and is pressed down. There is no hindrance.

来る、といった効果がある。As described above, according to the present invention, since the movement of the moving body consists of the movement of the sewing machine in the cloth feeding direction and the vertical direction and the rotation, a large space space is normally secured on the cloth feeding side. At the same time, there is an effect that the wiper can perform a reliable yarn removing operation when the upper yarn is removed. Moreover, since the guide groove and the long groove are provided with the support, there is an effect that a complicated operation of the wiper can be realized with a small number of parts, a compact and simple configuration.
