＜技術分野＞
本考案は無杼織機のドラム式緯糸貯留装置に関
し、特に緯糸のセツトを容易にするための改良に
関する。[Detailed Description of the Invention] <Technical Field> The present invention relates to a drum-type weft storage device for a shuttleless loom, and particularly to an improvement for facilitating the setting of weft yarns.
＜従来技術＞
従来のドラム式緯糸貯留装置として、特開昭58
−70748号公報に示すようなものがある。すなわ

より静止ドラムに緯糸を巻付けて貯留する。<Prior art> As a conventional drum-type weft storage device,
There is one as shown in the -70748 publication. In other words, the drum is supported at the tip of the rotating shaft so that it can rotate freely, and the drum is held stationary by the attraction between the magnet attached to the drum and the magnet attached to the bearing of the rotating shaft. . After the weft is passed through the insertion hole in the center of the rotating shaft, it is guided through a pipe-shaped thread guide that is integrally attached to the rotating shaft and revolves around the stationary drum. The weft is wound around a stationary drum and stored.
ところで、このようなドラム式緯糸貯留装置に
おいて、緯糸をセツトする際は、回転軸の挿通孔
へ空気を吹込んでその空気流に乗せて緯糸をパイ
プ状糸案内まで引通すようにする。 By the way, in such a drum-type weft storage device, when setting the weft, air is blown into the insertion hole of the rotary shaft, and the weft is carried by the airflow to the pipe-shaped yarn guide.
しかし、ドラムを静止状態に保つための磁石を
近接させる必要から、磁石間を通るパイプ状糸案

さいため、挿通孔内に吹込んだ緯糸引通し用の空
気が押しつぶし部の流量制約を受けて逆流し、こ
れがため緯糸をパイプ状糸案内にまで引通すこと
が困難であるという問題点があつた。 However, because it is necessary to place the magnets close together to keep the drum stationary, the middle part of the pipe-shaped thread guide that passes between the magnets is crushed, and the cross-sectional area of this crushed part is larger than the cross-sectional area of the insertion hole of the rotating shaft. Since the weft thread is small, the air blown into the insertion hole for weft thread passing flows backwards due to the flow rate restriction of the crushing part, which causes the problem that it is difficult to pass the weft thread through the pipe-shaped thread guide. It was hot.
＜考案の目的＞
本考案はこのような従来の問題点に鑑み、パイ
プ状糸案内の押しつぶし部による流量制約を緩和

After that, it is locked on the locking pin 21 or 22 on the drum 12 and then pulled through the weft inserting nozzle 30 in front of the drum 12, and the pipe-shaped yarn guide 26 is connected to the magnet 13 by the rotation of the rotating shaft 5.
By revolving around the drum 12 which is held stationary by the weft 16, the weft is wound around the drum 12 and stored, and at the weft insertion timing, it is pulled out by the weft insertion nozzle 30 and inserted. Reference numeral 31 is a cover for regulating ballooning, and is fixed to the bracket 1 via a stay 32.

プ状糸案内２６に引通される。 Therefore, when drawing the weft yarn 29 through, pressurized air is supplied from the pipe 39. Then, pressurized air is ejected from the air outlet 33 and the inside of the yarn guide tube 24 becomes negative pressure, so when the weft 29 is brought close to the entrance of the yarn guide tube 24, it is drawn in by the negative pressure flow, and the yarn guide tube 24 is pulled in by the negative pressure flow. It reaches the insertion hole 23 from the hole 25 and is then drawn through the insertion hole 23 into the pipe-like yarn guide 26 riding on the jet flow from the air jet port 33 .

すことができる。 At this time, although the cross-sectional area of the compressed part 27 of the pipe-shaped thread guide 26 is smaller than the cross-sectional area of the insertion hole 23 of the rotating shaft 5, some of the air escapes from the air outlet 40 on the upstream side of the compressed part 27. , air will not leak to the thread guide hole 25 side. Further, since only a small amount of air escapes from the air outlet 40 and most of it flows through the crushing part 27,
The weft yarn 29 does not fly out from the air outlet 40, and the weft yarn 29 can be reliably drawn into the pipe-like yarn guide 26.
尚、この実施例では、緯糸貯留装置の内部に空
気噴出口を設けているが、緯糸貯留装置とは別に
設けるようにしてもよい。 In this embodiment, the air outlet is provided inside the weft storage device, but it may be provided separately from the weft storage device.
