Description
【０００１】[0001]
本考案は、互いに平行に共通の旋回軸に沿って設けられていてかつ端部に形成 されている半環状の凹部を介してこの旋回軸にそれぞれ支持されている多数列の ヘルド牽引レバーを備えている織機に使用されるドビー機の開口動作を制御する ための装置、特に一方において所属するヘルド牽引作動機構と結合しており、他 方においてヘルド牽引ロープ或いはヘルド牽引ロッドを介してヘルド枠と結合し ているヘルド牽引レバーの構造に関する。 The present invention comprises a plurality of rows of heald traction levers which are provided parallel to each other along a common swivel axis and are each supported by the swivel axis via semi-annular recesses formed at the ends. Device for controlling the shedding movement of a dobby machine used in a weaving machine, in particular on the one hand associated with the associated heald traction actuation mechanism, and on the other hand with a heald frame via a heald traction rope or heald traction rod. Concerning the structure of the combined heald traction lever.
【０００２】[0002]
この様式の公知の装置にあってはヘルド牽引レバーは共通の軸上に互いに並列 して支承されており、この軸は装置の機枠の側壁に固定されている。この目的の ためヘルド牽引レバーの各々は環状の孔を備えており、この孔を上記の共通の軸 が貫通している。ヘルド牽引レバーの一つにのみ障害が生じた際全ヘルド牽引レ バーを完全に解体することなく修繕を容易にするため、ヘルド牽引レバーに環状 の孔を形成する代わりに、その端部の一端において半環状の凹部を形成し、この 凹部で以てヘルド牽引レバーを共通の軸の円筒形の周面に支持することが提案さ れている。 In the known device of this type, the heald traction levers are mounted side by side on a common shaft, which shaft is fixed to the side wall of the machine frame of the device. For this purpose, each of the heald traction levers is provided with an annular bore, through which the common shaft extends. In order to facilitate repair without completely dismantling the entire heald traction lever when only one of the heald traction levers fails, instead of forming an annular hole in the heald traction lever, one end of its end is used. It has been proposed to form a semi-annular recess in which the heald traction lever is supported on the cylindrical peripheral surface of a common shaft.
【０００３】 現代においては織機の速度は益々高速となり、これに伴いこの織機のヘルド或 いは相応する装置類、特にヘルドの一連の駆動力伝達機構システムの最後の伝達 部材であるヘルド牽引レバーは、益々過大になる動力の負荷を受ける。この際、 ヘルド牽引レバーと共通の軸の周面間で生じる摩擦は隣接し合っているヘルド牽 引レバーの側方において生じる摩擦と相まって、過度の加熱を生じ、この加熱に より装置の正常な作動が阻害され、高い摩耗が生じる。In modern times, the speed of the loom is getting higher and higher, and accordingly, the healds of the loom or the corresponding devices, especially the heald traction lever which is the last transmission member of the series of driving force transmission mechanism of the heddle. , Receives an increasing load of power. At this time, the friction generated between the heald pulling lever and the peripheral surface of the common shaft is combined with the friction generated on the side of the adjacent heald pulling levers to cause excessive heating, which causes normal operation of the device. Operation is impeded and high wear occurs.

本考案は、上記のような欠点を持たない冒頭に記載した様式の、ドビー機の開 口動作を制御する装置を提供することである。 The invention is to provide a device for controlling the opening movement of a dobby machine, of the type described at the outset, which does not have the disadvantages mentioned above.
【０００５】[0005]
上記の課題は本考案により、共通の旋回軸の円筒形の周面とヘルド牽引レバー の各々の半環状の凹部との間にそれぞれ一つのボール軸受或いはニードル軸受が 設けられており、それぞれのヘルド牽引レバーの半環状の凹部に当接するこれら 軸受の外側リングが外方に突出している二つのウエッブを備えており、これらの ウエッブが上記旋回軸に支持されるヘルド牽引レバーの端部のための案内部を形 成していることによって解決される。 According to the present invention, one of the ball bearings or needle bearings is provided between the cylindrical peripheral surface of the common swivel shaft and each semi-annular recess of the heald traction lever. The outer ring of these bearings, which abuts the semi-annular recess of the traction lever, comprises two outwardly projecting webs, the webs for the ends of the heald traction lever being supported on said pivot. It is solved by forming the guide.

図１において全体を参照符号１で示した消極ドビー機ヘルド牽引レバーは、概 略図で示した動力伝達装置、例えばヘルド牽引ロープ２を介してドビー機に所属 している織機のヘルド枠３と結合されている。このようなヘルド牽引レバー１の 各々は一方の端部においてドビー機の全てのヘルド牽引レバーに共通の固定され ている旋回軸４に支持されており、他方の端部においてヘルド牽引作動機構５と 結合されている。 In FIG. 1, a depolarizing dobby machine heald traction lever generally designated by reference numeral 1 is connected to a heald frame 3 of a loom belonging to the dobby machine via a power transmission device shown in the schematic diagram, for example, a heald traction rope 2. Has been done. Each such heald traction lever 1 is supported at one end by a fixed swivel shaft 4 which is common to all the heald traction levers of the dobby machine, and at the other end by a heald traction actuating mechanism 5 Are combined.
【０００７】 図示した実施例にあっては上記のヘルド牽引作動機構５はヘルド牽引レバー１ の一端に設けられているリンク部６ａ内に軸受されている二腕状の揺動レバー６ を備えている。この揺動レバー６は両端にそれぞれ一つのフック７を備えている 。リンク機構１０を中心にして揺動する揺動レバー９に設けられているストッパ ーバー８の作用の下に、上記のフック７は選択的に（ここでは図示していない） ナイフと作用係合する。これらのナイフの運動はドビー機のプログラム読取り装 置により織組織プログラムに依存して制御される。しかし作動装置５は他の公知 の様式で、例えば回転駆動機構を備えたドビーの場合ヘルド牽引レバー駆動機構 或いはカム駆動機構として構成することも可能である。In the illustrated embodiment, the above-mentioned heald pulling operation mechanism 5 is provided with a two-armed swing lever 6 bearing in a link portion 6 a provided at one end of the heald pulling lever 1. There is. The swing lever 6 is provided with one hook 7 at each end. Under the action of a stopper bar 8 provided on a swing lever 9 which swings around a link mechanism 10, the hook 7 mentioned above selectively engages with a knife (not shown here). .. The movement of these knives is controlled by the program reading device of the dobby machine depending on the weave program. However, the actuating device 5 can also be configured in other known manners, for example a heald traction lever drive mechanism or a cam drive mechanism in the case of a dobby with a rotary drive mechanism.
【０００８】 共通の旋回軸４と共働するヘルド牽引レバー１の各々の端部は公知の様式で半 環状の凹部１ａを備えており（図２参照）、これによりヘルド牽引レバー１はこ の凹部で以てこの旋回軸の円筒形の周面に回転運動可能に支持される。本考案に より凹部１ａと旋回軸４の周面との間にはころ軸受が設けられている。Each end of the heald traction lever 1 cooperating with the common swivel axis 4 is provided with a semi-annular recess 1a in a known manner (see FIG. 2), whereby the heald traction lever 1 is provided with this. It is rotatably supported on the cylindrical peripheral surface of the swivel shaft by means of a recess. According to the present invention, a roller bearing is provided between the recess 1a and the peripheral surface of the swivel shaft 4.
【０００９】 図示した実施例にあっては、上記のころ軸受は一列の軸受ニードル１１ａを備 えており、これらの軸受ニードルは旋回軸４の周面と外方リング１１との間に設 けられている。この外方リング１１は外方へと突出している二つのウエッブ１１ ｂを備えており、これらのウエッブ間においてヘルド牽引レバー１はその半環状 の凹部１ａで以てこれらのウエッブの側方で案内される。In the illustrated embodiment, the roller bearing described above is provided with a row of bearing needles 11 a, which are arranged between the peripheral surface of the swivel shaft 4 and the outer ring 11. ing. This outer ring 11 comprises two webs 11b projecting outwards, between which the heald pulling lever 1 is guided laterally by these semi-annular recesses 1a. To be done.
【００１０】 軸受ニードル１１ａ−この軸受ニードルの代わりに他の転動体、例えばボール 体を使用することも可能である−は旋回軸４に沿って回転運動するヘルド牽引レ バー１の支持を著しく改善し、他方側方のウエッブ１１ｂは個々のヘルド牽引レ バー１を互いに離間した状態で保持し、従って互いに隣接し合っているヘルド牽 引レバー１間には何等摩擦が生じない。このようにして、ヘルド牽引レバー１が 作動の際こおおむる負荷に依存することなく、ヘルド牽引作動機構部分の許容し がたい過熱が回避され、しかもその際半環状の凹部１ａ上で支持が行われている ことにより達せられる修繕し易さが阻害れさることがないと言う利点が得られる 。The bearing needle 11a-it is possible to use other rolling elements, for example balls, instead of this bearing needle-significantly improves the support of the heald traction lever 1 rotating about the swivel axis 4. On the other hand, the web 11b on the other side holds the individual heald pulling levers 1 apart from each other, so that no friction occurs between the heald pulling levers 1 adjacent to each other. In this way, unacceptable overheating of the heald traction actuating mechanism part is avoided without depending on the prevailing load when the heald traction lever 1 operates, and at the same time the support on the semi-annular recess 1a The advantage is that the ease of repair that can be achieved is not hindered.
【００１１】 本考案による構成は、上記した実施例の個々の構成に限定されず、本考案によ る構成の範囲を逸脱することなく多様に変形可能である。The configuration according to the present invention is not limited to the individual configurations of the above-described embodiments, and can be variously modified without departing from the scope of the configuration according to the present invention.
【００１２】[0012]
本考案により上記のようにヘルド牽引レバーと旋回軸の間に軸受として転動体 が設けられていることにより、共通の旋回軸上でのヘルド牽引レバーの回転運動 性が改善される。同時に、外方リングのウエッブによる側方での案内によりヘル ド牽引レバーが互いに離間された状態で保持され、従って互いに接触し合うこと がない。 According to the present invention, since the rolling element is provided as a bearing between the heald traction lever and the swivel shaft as described above, the rotational movability of the heald traction lever on the common swivel shaft is improved. At the same time, the lateral guidance by the web of the outer ring keeps the heald traction levers apart from one another and thus prevents them from touching each other.
