Description

【考案の詳細な説明】 「産業上の利用分野」 本考案は力織機における箔引装置に係る。[Detailed explanation of the idea] "Industrial application field" The present invention relates to a foil drawing device for a power loom.

「従来の技術」 従来箔引装置は箆を経糸開口中に通入し同箆端
に箔糸を引掛け箆を後退させて経糸中に箔糸を織
込むのが通例である。``Prior Art'' Conventional foil pulling devices usually pass a spatula into a warp opening, hook a foil thread onto the end of the spatula, and then move the spatula back to weave the foil thread into the warp threads.

「考案が解決しようとする問題点」 しかし上記技術によるときは箔糸の左右端部が
不均揃なる箔織物の製作される欠点がある。``Problems to be Solved by the Invention'' However, when using the above technique, there is a drawback that a foil fabric is produced in which the left and right ends of the foil threads are uneven.

「問題を解決するための手段」 本考案は基体１の中央上部に形成した椀形状凹
窪部２の底部に縦孔３を形成し同孔３にソレノイ
ド鉄芯摺動用横孔５を接続してこれに同鉄芯４を
装入し、該縦孔３下端にこれと直交状に交差する
光センサーの導光管配置用横孔６を形成して同孔
６に導光管７，７′を配置してなるものである。"Means for Solving the Problem" The present invention forms a vertical hole 3 at the bottom of a bowl-shaped recess 2 formed in the upper center of the base body 1, and connects a horizontal hole 5 for sliding the solenoid iron core to the hole 3. The iron core 4 is inserted into this, a horizontal hole 6 for arranging the light guide tube of the optical sensor is formed perpendicularly to the lower end of the vertical hole 3, and the light guide tubes 7, 7 are inserted into the hole 6. ′ is arranged.

図中５は縦孔３に形成した鉄芯４端の衝合する
凹所である。８は基体１上面に形成した箆先案内
用凹欠部、９は光センサーの発光部、９′は同受
光部、１０は掃除孔、１１は台である。 In the figure, 5 is a recess formed in the vertical hole 3 where the ends of the iron core 4 abut against each other. Reference numeral 8 designates a recessed part for guiding the tip of the spatula formed on the upper surface of the base body 1, 9 a light emitting part of an optical sensor, 9' a light receiving part thereof, 10 a cleaning hole, and 11 a stand.

本装置に於て光センサーとソレノイドは互に関
係させて、光センサーの投光が遮断されたときソ
レノイドが作動するよう装置しておき、又電動式
箆が後退復元したときソレノイドの鉄芯も復元
し、箔糸の端部は従つて離脱し、光センサーは投
光するよう構成しておくものとする。なお箔糸は
定寸に切断されたものを使用する。又本装置は筬
框に取付けるものとする。 In this device, the light sensor and the solenoid are connected to each other so that the solenoid is activated when the light emitted from the light sensor is cut off, and the iron core of the solenoid is also activated when the electric broom returns to its original position. When restored, the end of the foil thread is then detached and the light sensor is configured to emit light. Note that the foil thread used must be cut to size. Additionally, this device shall be installed on a reed stile.

「作用」 本考案は上記の構造よりなるから、箔糸ａは凹
窪部２のため容易に縦孔３に案内降下せしめら
れ、従つてその降下は確実容易化せしめられる。``Function'' Since the present invention has the above-described structure, the foil yarn a can be easily guided down into the vertical hole 3 due to the concave portion 2, and its descent is certainly facilitated.

かくして箆ｂの先端孔１２内に降下し凹窪部２
を経て縦孔３に降下し同孔底部に到達した箔糸ａ
端部は、光センサーの投光を遮断するや直ちにソ
レノイドの鉄芯４が作動して同芯４によつて挟圧
され（第３図及第５図）、続いて箆は後退し箔糸
を引いて（第６図）経糸中に通入し、而して同箆
の後退と共にソレノイドの鉄芯も復元するに至
る。 In this way, it descends into the tip hole 12 of the spatula b, and the concave part 2
The foil yarn a descends into the vertical hole 3 through the hole and reaches the bottom of the hole.
As soon as the light emitted from the optical sensor is interrupted, the iron core 4 of the solenoid is activated and the end is pinched by the concentric core 4 (Figures 3 and 5), and then the spatula retreats and the foil thread is pressed. (Fig. 6) and passes through the warp threads, and as the knuckle retreats, the iron core of the solenoid also returns to its original state.

「考案の効果」 従つていずれの箔糸もその挟圧される個所は同
位置となるため、箔糸織込みに際し箔糸の織端が
均揃されるに至る効果がある。``Effect of the invention'' Therefore, since all the foil threads are pressed at the same position, there is an effect that the edges of the foil threads are evenly aligned when weaving the foil threads.
