Description

【0001】
【発明の属する技術分野】
本発明は、空気噴射式織機の緯入れ装置に関する。
【0002】
【従来の技術】
特開平8−311743号公報に開示された空気噴射式織機の緯入れ装置によれば、複数の空気噴射口を有する共通の電磁弁を介して空気を供給される複数のサブノズルと複数の空気噴射口を有する他の共通の電磁弁を介して空気を供給される他の複数のサブノズルとが、緯入れ方向に交互に配置されていて、各緯入れサイクル毎に、前記サブノズルが、所定の順序で順次選択されて空気噴射動作を行なうことで、同じ経糸のみが繰り返し空気の吹き付けにさらされて織布に経筋状の色斑が発生することを防止している。
【0003】
【発明が解決しようとする課題】
しかし、サブノズルへの圧縮空気の供給開始及び終了タイミングを制御する電磁弁は、従来では、図4に示すように緯入れ方向に並設され、隣設する電磁弁は、サブノズルへ連結されるチュ−ブ等の配管と電磁弁とが干渉しないように十分に距離をおいて配設される。この場合、共通の電磁弁内で、サブノズルへの配管長さのばらつきが大きくなるので、次のような問題が生じる。
【0004】
すなわち、サブノズルへの配管が長い場合には、短い場合に比べて電磁弁が開いてから実際にサブノズルの噴射が開始するタイミングが遅れ、かつ噴射終了後の残圧が長く残る(応答性が悪い)。一方、サブノズルへの配管が短い場合には、長い場合に比べて電磁弁が開いてから実際にサブノズルの噴射が開始するタイミングが早くなり、かつ噴射終了後の残圧期間は短い(応答性がよい)。従って、共通の電磁弁内で、サブノズルへの配管長さのばらつきが大きくなると、各々のサブノズルの噴射開始タイミング及び噴射終了後の残圧期間のばらつきが大きくなり、緯糸飛走が不安定になる。
【0005】
そこで本発明は、上記のような問題点に着目してなされたもので、複数の空気噴射口を有する共通の電磁弁を介して空気を供給される複数のサブノズルと複数の空気噴射口を有する他の共通の電磁弁を介して空気を供給される他の複数のサブノズルとを緯入れ方向に交互に配置させて、各緯入れサイクル毎に、前記サブノズルが、所定の順序で順次選択されて空気噴射動作を行なう際に、安定な緯入れを行なうことを目的とする。
【0006】
【課題を解決するための手段】
前記目的を達成するために、本発明では、複数の空気噴射口を有する共通の電磁弁を介して空気を供給される複数のサブノズルと、複数の空気噴射口を有する他の共通の電磁弁を介して空気を供給される他の複数のサブノズルとが、緯入れ方向に交互に配置されている緯入れ装置において、上記両電磁弁が、経糸方向でみて少なくとも一部が重複して配置されるように構成されている。
【0007】
【作用】
本発明の構成によれば、緯入れ方向に交互に配置されたサブノズルに係る2つの電磁弁は、経糸方向に位置を異ならせると共に緯入れ方向及び織機の上下方向に十分に近接して配置されるので、サブノズルへ連結されるチューブ等の配管と電磁弁とが干渉することなく、また、サブノズルへ連結されるチューブ等の配管同士が干渉することもない。そして、さらに、共通の電磁弁内におけるサブノズルへの配管長さのばらつきを小さくすることができるため、共通の電磁弁内における各々のサブノズルの噴射開始タイミング及び噴射終了後の残圧期間のばらつきが小さくなり、緯糸の飛走が安定する。
【0008】
【発明の実施の形態】
以下、図1から図3を以て発明の実施の形態を説明する。
【0009】
緯糸Yは、図1に示すように、メインノズルMの噴射と、給糸側から反給糸側へ亘り所定間隔で配置され、複数本のグループ単位で給糸側から反給糸側へ順次噴射するサブノズルの噴射との協働により、経糸開口内Kに緯入れされる。
【0010】
図1には、斜線を施してないサブノズル(以下、A系列のサブノズルとする)と斜線を施したサブノズル(以下、B系列のサブノズルとする)とが図示してある。一般には、前者のみで構成されるが、本図では、後者を追加して、前者と後者とを交互に配列して、各緯入れサイクル毎に、前者と後者とを所定の順序で順次選択して空気噴射を行なうことで、同じ経糸のみが繰り返し空気の吹き付けにさらされて織布に経筋状の色斑が発生することを防止している。なお、図1には、サブノズルは給糸側から16本目まで図示してあるが、それ以降のサブノズルの図示は省略してある。また、上記サブノズルの系列は2系列に限定せず、3系列以上用いてもよい。
【0011】
A系列のサブノズルA1〜A8は、給糸側の最端に位置するサブノズルA1からA4までの4本がグループ化され、共通のマニホールド11Aに設けられた空気噴射口から柔軟性のある配管C1〜C4により連結され空気が供給される。続いて、サブノズルA5からA8までの4本がグループ化され、共通のマニホールド12Aに設けられた空気噴射口から柔軟性のある配管C5〜C8により連結され空気が供給される。前記マニホールド11Aには電磁弁21Aが連結され、マニホールド12Aには電磁弁22Aが連結されている。サブノズルA1〜A4は、電磁弁21Aにより噴射開始及び終了タイミングが制御され、サブノズルA5〜A8は、電磁弁22Aにより噴射開始及び終了タイミングが制御される。なお、電磁弁とマニホールドとは、図1のような分離型に限らず、両者一体成形されたものであってもよい。
【0012】
また、B系列のサブノズルB1〜B8は、A系列のサブノズルA1〜A8の間に順次配設され、最も給糸側に位置するB1からB4までの4本がグループ化され、共通のマニホールド11Bに設けられた空気噴射口から柔軟性のある配管D1〜D4により連結され空気が供給される。続いて、サブノズルB5からB8までの4本がグループ化され、共通のマニホールド12Bに設けられた空気噴射口から柔軟性のある配管D5〜D8により連結され空気が供給される。前記マニホールド11Bには電磁弁21Bが連結され、マニホールド12Bには電磁弁22Bが連結されている。サブノズルB1〜B4は、電磁弁21Bにより噴射開始及び終了タイミングが制御され、サブノズルB5〜B8は、電磁弁22Bにより噴射開始及び終了タイミングが制御される。なお、上記の場合、グループ化されたサブノズルは、いずれも4本であるが、4本に限定されるものではなく、3〜5本が一般的であり、各グループともに同一数にする必要はない。また、複数系列を有するグループは、織幅全域に亘る全てのグループに適用されてもよいし、部分的に1グループ(例えば最終グループのみ)又は複数グループに適用されてもよい。
【0013】
各電磁弁21A、21B、22A、22Bは、共通の圧力容器1及びレギュレータ2を介して圧力空気源3に接続されている。各電磁弁21A、21B、22A、22Bはまた制御装置4に電気的に接続されて、その開閉動作を制御装置4により制御される。この制御装置4は、織機の主軸7に付設されたエンコーダ6に接続されて、エンコーダ6から織機の回転角度信号θが入力されて、所定のタイミングで開閉動作を行なう。また、制御装置4には、噴射選択装置5が接続されており、噴射選択装置5からの選択信号Sにより、電磁弁21Aと21Bとのどちらかが選択され、また、電磁弁22Aと22Bとのどちらかが選択されて、選択された電磁弁から所望のサブノズルに空気が供給される。
【0014】
電磁弁21Aと電磁弁21Bとは、図1及び図2に示すように、経糸方向に位置を異ならせて、かつ経糸方向でみて重複配置され、図示しないブレストビーム等に直接又は図示しないブラケット等を介して配置される。また、電磁弁22Aと電磁弁22Bとについても同様である。但し、図2のように、経糸方向でみて完全に重ならなくてもよく、経糸方向でみて少なくとも一部が重複されていればよい。すなわち、緯入れ方向又は織機の上下方向にずれていてもよい。(図1の状態)。また、図3に示すように、両電磁弁は、経糸方向に離間して配置されてもよい。この場合は、配管同士の干渉の危険性がほぼ無くなる。
【0015】
上記のような電磁弁の配置にすれば、例えば、図1に示すサブノズルB1〜B4の配管D1〜D2の各々の長さのばらつきと、図3(従来例)に示すサブノズルB1〜B4の配管D1〜D2の各々の長さのばらつきとを比較すれば明らかなように、本発明の実施形態である図1に示す方が、配管の長さのばらつきが少ない。すなわち、目的とする緯入れの安定化が十分達成されることになる。
【0016】
【発明の効果】
本発明によれば、複数の空気噴射口を有する共通の電磁弁を介して空気を供給される複数のサブノズルと複数の空気噴射口を有する他の共通の電磁弁を介して空気を供給される他の複数のサブノズルとを緯入れ方向に交互に配置させて、各緯入れサイクル毎に、前記サブノズルが所定の順序で順次選択されて空気噴射動作を行う際に、上記両電磁弁を経糸方向でみて少なくとも一部が重複して配置されることにより、上記両電磁弁の複数の空気噴射口からサブノズルへの配管長さのばらつきを少なくすることができ、安定な緯入れを行うことが可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a weft insertion device for an air jet loom.
[0002]
[Prior art]
According to the weft insertion device for an air-jet loom disclosed in Japanese Patent Application Laid-Open No. 8-31743, a plurality of sub-nozzles and a plurality of air jets are supplied with air through a common solenoid valve having a plurality of air jet ports. Another plurality of sub-nozzles supplied with air through another common solenoid valve having a mouth are alternately arranged in the weft insertion direction, and for each weft insertion cycle, the sub-nozzles are arranged in a predetermined order. By performing the air jetting operation sequentially by selecting the same, it is possible to prevent the same warp yarn from being repeatedly exposed to the blowing of air, thereby preventing warp-like color spots from occurring on the woven fabric.
[0003]
[Problems to be solved by the invention]
However, conventionally, solenoid valves for controlling the start and end timings of the supply of compressed air to the sub-nozzles are arranged side by side in the weft insertion direction as shown in FIG. 4, and an adjacent solenoid valve is a tube connected to the sub-nozzle. -The solenoid valve is arranged at a sufficient distance so as not to interfere with piping such as a valve. In this case, the variation in the length of the pipe to the sub-nozzle becomes large within the common solenoid valve, so that the following problem occurs.
[0004]
That is, when the piping to the sub-nozzle is long, the timing at which the injection of the sub-nozzle actually starts after the solenoid valve is opened is delayed compared to when the piping is short, and the residual pressure after the end of the injection remains long (poor responsiveness). ). On the other hand, when the pipe to the sub-nozzle is short, the timing at which the injection of the sub-nozzle actually starts after the solenoid valve is opened is earlier than when the pipe is long, and the residual pressure period after the end of the injection is short (response is shorter). Good). Therefore, in a common solenoid valve, when the variation of the pipe length to the sub-nozzles increases, the variation of the injection start timing of each sub-nozzle and the residual pressure period after the end of the injection increases, and the weft flight becomes unstable. .
[0005]
Accordingly, the present invention has been made in view of the above problems, and has a plurality of sub-nozzles and a plurality of air injection ports to which air is supplied through a common electromagnetic valve having a plurality of air injection ports. By alternately arranging a plurality of sub-nozzles supplied with air through another common electromagnetic valve in the weft insertion direction, for each weft insertion cycle, the sub-nozzles are sequentially selected in a predetermined order. An object of the present invention is to perform stable weft insertion when performing an air injection operation.
[0006]
[Means for Solving the Problems]
In order to achieve the object, in the present invention, a plurality of sub-nozzles supplied with air through a common electromagnetic valve having a plurality of air injection ports, and another common electromagnetic valve having a plurality of air injection ports. In a weft insertion device in which the other plurality of sub-nozzles to which air is supplied via are alternately arranged in the weft insertion direction, the two solenoid valves are at least partially overlapped when viewed in the warp direction. It is configured as follows.
[0007]
[Action]
According to the configuration of the present invention, the two solenoid valves related to the sub-nozzles alternately arranged in the weft insertion direction have different positions in the warp direction and are arranged sufficiently close to the weft insertion direction and the vertical direction of the loom. Therefore, there is no interference between the piping such as a tube connected to the sub-nozzle and the solenoid valve, and there is no interference between the piping such as the tube connected to the sub-nozzle. Further, since the variation in the pipe length to the sub-nozzle in the common solenoid valve can be reduced, the variation in the injection start timing of each sub-nozzle in the common solenoid valve and the variation in the residual pressure period after the end of the injection are reduced. It becomes smaller and the flight of the weft becomes stable.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS.
[0009]
As shown in FIG. 1, the weft yarns Y are arranged at predetermined intervals from the injection of the main nozzle M to the yarn supply side to the non-yarn supply side, and sequentially from the yarn supply side to the non-yarn supply side in a plurality of groups. By cooperating with the ejection of the ejecting sub-nozzle, weft is inserted into the warp opening K.
[0010]
FIG. 1 illustrates a sub-nozzle without diagonal lines (hereinafter, referred to as an A-series sub-nozzle) and a sub-nozzle with diagonal lines (hereinafter, referred to as a B-series sub-nozzle). Generally, the former is composed of only the former, but in this figure, the latter is added, the former and the latter are alternately arranged, and the former and the latter are sequentially selected in a predetermined order in each weft insertion cycle. By performing the air jetting, it is possible to prevent the same warp yarn from being repeatedly exposed to the blowing of air, thereby preventing warp-like color spots from occurring on the woven fabric. In FIG. 1, the sub-nozzles are shown from the yarn supply side to the 16th, but illustration of the sub-nozzles thereafter is omitted. The number of the sub-nozzles is not limited to two but may be three or more.
[0011]
The sub-nozzles A1 to A8 of the A series are grouped into four sub-nozzles A1 to A4 located at the end on the yarn supply side, and have flexible pipes C1 to C1 from air injection ports provided in the common manifold 11A. Air is supplied by being connected by C4. Subsequently, four sub nozzles A5 to A8 are grouped, and air is supplied from flexible air pipes C5 to C8 from air injection ports provided in the common manifold 12A. A solenoid valve 21A is connected to the manifold 11A, and a solenoid valve 22A is connected to the manifold 12A. The injection start and end timings of the sub-nozzles A1 to A4 are controlled by the electromagnetic valve 21A, and the injection start and end timings of the sub-nozzles A5 to A8 are controlled by the electromagnetic valve 22A. Note that the solenoid valve and the manifold are not limited to the separated type as shown in FIG. 1 and may be formed integrally with each other.
[0012]
The B-series sub-nozzles B1 to B8 are sequentially arranged between the A-series sub-nozzles A1 to A8, and the four nozzles B1 to B4, which are located closest to the yarn supply side, are grouped to form a common manifold 11B. Air is supplied from the provided air injection ports through flexible pipes D1 to D4. Subsequently, the four nozzles B5 to B8 are grouped, and air is supplied from flexible air pipes D5 to D8 from air injection ports provided in the common manifold 12B. An electromagnetic valve 21B is connected to the manifold 11B, and an electromagnetic valve 22B is connected to the manifold 12B. The injection start and end timings of the sub nozzles B1 to B4 are controlled by the electromagnetic valve 21B, and the injection start and end timings of the sub nozzles B5 to B8 are controlled by the electromagnetic valve 22B. In the above case, the number of sub-nozzles in each group is four, but the number is not limited to four, and three to five nozzles are generally used. Absent. Further, the group having a plurality of groups may be applied to all groups throughout the weaving width, or may be partially applied to one group (for example, only the last group) or a plurality of groups.
[0013]
Each of the solenoid valves 21A, 21B, 22A, 22B is connected to a pressure air source 3 via a common pressure vessel 1 and a regulator 2. Each of the solenoid valves 21A, 21B, 22A, 22B is also electrically connected to the control device 4, and the opening and closing operations thereof are controlled by the control device 4. The control device 4 is connected to an encoder 6 attached to a main shaft 7 of the loom, receives a rotation angle signal θ of the loom from the encoder 6, and performs opening and closing operations at a predetermined timing. Further, an injection selection device 5 is connected to the control device 4, and one of the solenoid valves 21A and 21B is selected by a selection signal S from the injection selection device 5, and the solenoid valves 22A and 22B are connected to each other. Is selected, and air is supplied from the selected solenoid valve to the desired sub-nozzle.
[0014]
As shown in FIGS. 1 and 2, the solenoid valve 21A and the solenoid valve 21B are arranged at different positions in the warp direction and overlapped in the warp direction, and are directly mounted on a breast beam (not shown) or a bracket (not shown). Is arranged through. The same applies to the solenoid valve 22A and the solenoid valve 22B. However, as shown in FIG. 2, it is not necessary to completely overlap in the warp direction, and it is sufficient that at least a part of the parts overlap in the warp direction. That is, it may be shifted in the weft insertion direction or the vertical direction of the loom. (State of FIG. 1). Further, as shown in FIG. 3, the two solenoid valves may be arranged apart from each other in the warp direction. In this case, there is almost no danger of interference between the pipes.
[0015]
With the arrangement of the solenoid valves as described above, for example, variations in the lengths of the pipes D1 to D2 of the sub nozzles B1 to B4 shown in FIG. 1 and the pipes of the sub nozzles B1 to B4 shown in FIG. As is clear from comparison of the variation in the length of each of D1 and D2, the variation in the length of the pipe is smaller in the embodiment of the present invention shown in FIG. That is, the intended stabilization of weft insertion is sufficiently achieved.
[0016]
【The invention's effect】
According to the present invention, air is supplied through a plurality of sub-nozzles supplied with air through a common electromagnetic valve having a plurality of air injection ports and another common electromagnetic valve having a plurality of air injection ports. The other plurality of sub-nozzles are alternately arranged in the weft insertion direction, and for each weft insertion cycle, when the sub-nozzles are sequentially selected in a predetermined order to perform the air injection operation, the two solenoid valves are turned in the warp direction. As a result, it is possible to reduce the variation in the pipe length from the plurality of air injection ports of the two solenoid valves to the sub-nozzle, and to perform stable weft insertion. It becomes.
