Description

この発明は、織機のカム織機構とそのような機構を取付けた織機とそのような機構を組立てる方法に関する。   The present invention relates to a loom cam weaving mechanism, a loom fitted with such a mechanism, and a method of assembling such a mechanism.

織機の分野では、カム織機構は、織機に据え付けられるヘドルフレームの数に等しい数の連続振動レバーから成り、各振動レバーがフレームの一つに連結されて共通軸により回転される適合カムの二つの軌道と交差する二つのローラを取り付けられるように設計されていることが知られている。機構の初期製造中、或いは織の修正中に通常には４と１２の間の数のカムはその駆動軸に据え付けられなければならない。これらカムはカムとカム従動子の隣接軌道間の隙間を極めて大きな程度には防止するか、或いは制限するために大きな精度により据え付けられなければならない。   In the field of looms, the cam weaving mechanism consists of a number of continuous vibration levers equal to the number of heddle frames installed in the loom, each of which is connected to one of the frames and rotated by a common shaft. It is known to be designed to be able to mount two rollers that intersect two tracks. During initial manufacture of the mechanism or during weaving modification, usually between 4 and 12 cams must be installed on the drive shaft. These cams must be installed with great accuracy to prevent or limit the gap between adjacent tracks of the cam and cam follower to a very large extent.

ある公知の機構では、機構のフレームは二つの半軸受を形成し、カムを取付けた共通軸がフレームにより形成された半軸受に据付けられた後に軸受の他方の半部を形成するカラー或いはフランジが半軸受に取付けられいる。この技術はフレームに対する軸の位置決めにおいて不正確度を包含するので、カム軸の軸線と振動レバーの関節の軸線との間の距離の値がこれら軸線の平行のように精度を保証されることができない。   In one known mechanism, the frame of the mechanism forms two half bearings, and a collar or flange that forms the other half of the bearing after the common shaft with the cam attached is installed in the half bearing formed by the frame. Installed on half bearing. Since this technique includes inaccuracies in the positioning of the shaft relative to the frame, the accuracy of the distance between the camshaft axis and the axis of the joint of the vibration lever can be guaranteed as parallel to these axes. Can not.

機構の主幾何学軸線の良好な位置決めを達成するために、二つのオリフィスが共通カム軸を支持するように形成されるフレームを軸受の介入により使用することは実際に知られている。この場合に、機構の外側のスリーブ或いはバレルに種々のカムを据え付け、次に回転を防止したカムと取付けられ且つ角度的に割出されたバレルを単片オリフィスが形成されるフレームの二つの部品間に置き、次にこれらオリフィスの一つを通して、スリーブを通して次に第二オリフィスを通して駆動軸を挿入させることは実際に知られている。この技術は、バレルが機構フレームに挿入されるときに重く嵩張る部品の取り扱いを必要とする。カムはベンチ上に機械の外側のバレルに据え付けられなければならなく、輸送手段を必要とし、時間を浪費する。
仏国特許第８６０２２５号明細書 米国特許第２６３７３４８号明細書 米国特許第３６０３３５１号明細書 In order to achieve a good positioning of the main geometric axis of the mechanism, it is actually known to use a frame with two orifices formed to support a common camshaft with bearing intervention. In this case, the two parts of the frame where the various cams are mounted on the sleeve or barrel outside the mechanism, then the cams that are prevented from rotating and attached to the angularly indexed barrel are formed with a single piece orifice It is actually known to insert the drive shaft in between and then through one of these orifices, then through the sleeve and then through the second orifice. This technique requires the handling of heavy and bulky parts when the barrel is inserted into the mechanism frame. The cam must be installed on the bench in the outer barrel of the machine, requires transport and is time consuming.

カムが機械自体の据え付けられ且つ取り外され得る織機構を提案して、時間を浪費せずに、特殊な工具を使用せずに、機構フレームとこれらカムと交差する振動レバーとに対して共通駆動軸の位置決めの位置を妥協せずに、発明が意図するこれら欠点をさらに取り除くことである。   Proposing a weaving mechanism in which the cam can be installed and removed from the machine itself, without wasting time, using a special tool, and a common drive for the mechanism frame and the vibrating levers that intersect these cams It is to further eliminate these disadvantages the invention intends without compromising the position of the shaft positioning.

それ故に、この発明は織機のカム織機構に関し、この機構は共通駆動軸に据え付けられ且つ振動レバーに据付けられたカム従動子自体のローラ軌道を備えた幾つかのカムから成り、前記駆動軸が機構フレームの二つの単片部品に形成された二つのオリフィスによって支持されていて、一方の単片部品が前記軸によって横断されている。この機構は、前記軸が第一オリフィスから第二オリフィスの方向にこれらオリフィス間の距離以下である長さにわたり延びているに対して、延長支持体を形成する分解可能な手段がこれらオリフィス間に位置した前記軸の端を第二オリフィスに連結し、そしてオリフィス間の距離と前記軸がオリフィス間に延びる長さの間の差はカムの幅より大きいことを特徴とする。   This invention therefore relates to a loom cam weaving mechanism, which consists of several cams mounted on a common drive shaft and provided with a roller track of the cam follower itself mounted on a vibration lever, said drive shaft being Supported by two orifices formed in two single piece parts of the mechanism frame, one single piece part being traversed by the shaft. This mechanism is such that the shaft extends from the first orifice in the direction of the second orifice over a length that is less than or equal to the distance between the orifices, whereas the releasable means forming the extended support is between the orifices. The end of the shaft located is connected to a second orifice and the difference between the distance between the orifices and the length the shaft extends between the orifices is greater than the width of the cam.

この発明によると、軸の端とフレームの部品の間に空間が形成され、第二オリフィスがフレーム部品に形成され、フレームにすでに据え付けられた軸にカムを据え付けるために、延長を形成する手段の挿入前、或いはその取出し後に、この空間を使用することを可能とする。カムはその駆動軸に個々に据え付けられるので、バレルを使用する必要がなく、各カムは容易な取り扱いと適合する重量と嵩を有する。   According to the invention, a space is formed between the end of the shaft and the part of the frame, a second orifice is formed in the frame part, and the means for forming an extension for mounting the cam on the shaft already mounted on the frame This space can be used before insertion or after removal. Since the cams are individually mounted on their drive shafts, there is no need to use a barrel, and each cam has a weight and bulk that is compatible with easy handling.

有益だが、必須ではない観点によると、織機構はすべての技術的に許容し得る組合せに採用された次の特徴の一つ以上を組み込み得る：
・延長支持体を形成する手段は二つのオリフィス間に位置された軸の端を支持する軸受を保持するか、或いは形成する。 In a beneficial but not essential aspect, the weaving mechanism can incorporate one or more of the following features employed in all technically acceptable combinations:

・延長支持体を形成する手段は軸の端に取り付けられ得て且つカムが回転するのを阻止するためにカムを掴持するように軸方向力をこの軸に据え付けたカムに働かし得る端片部材から成る。この端片部材は軸の端に回転するように有益にしっかりと取り付けられる。この端片部材はその端片部材が介入した軸受と共に挿入されるフレームの第二オリフィスにまで軸方向に延びている。   The means by which the extension support is formed can be attached to the end of the shaft and an end piece which can exert an axial force on the cam mounted on this shaft to grip the cam to prevent the cam from rotating It consists of members. This end piece is beneficially and securely attached to the end of the shaft for rotation. The end piece extends axially to the second orifice of the frame which is inserted with the bearing with which the end piece is intervening.

・延長支持体を形成する手段は第二オリフィスに分解自在にに据え付けられ且つ軸の端の方向に延びるスリーブから成る。このスリーブは取り囲むこの端に有益に延びていて、介入した軸受を備える。端片部材が設けられるならば、このスリーブは介入した軸受と共にこの端片部材に軸方向に延びている。   The means for forming the extension support comprises a sleeve which is releasably mounted in the second orifice and extends in the direction of the end of the shaft; The sleeve beneficially extends to this surrounding edge and includes an intervening bearing. If an end piece member is provided, the sleeve extends axially to the end piece member with an intervening bearing.

この発明は前述のように、織機構を備えた織機に関する。そのような織機はさらに経済的であり、構成することが容易であり、公知の織機よりさらに信頼できる。   As described above, the present invention relates to a loom equipped with a weaving mechanism. Such a loom is more economical, easy to construct and more reliable than known looms.

• The means for forming the extension support is releasably installed and this end is connected to an orifice formed in said part of the frame.

この発明はより良く理解され、そして発明の他の利点は、単に例として与えられ且つ添付図面を参照して行われる織機構、織機とその原理による方法の二つの実施態様の次の記述の観点でさらに明らかになる。   The invention is better understood, and other advantages of the invention are given in view of the following description of two embodiments of a weaving mechanism, a weaving machine and a method according to its principle given by way of example only and made with reference to the accompanying drawings. It will become clearer.

図１に示された織機Ｍは、幾つかのヘドルフレームから成り、そのひとつのみがこの図において参照符号１により見ることができる。織機Ｍの種々のフレームは、二重矢印Ｆ1 により示され且つカム機構１０により与えられた縦振動運動で作動し、このカム機構の出力レバーが湾曲レバー１３と連動されて且つ連結ロッド１４によりフレームに一体に連結されたそれぞれ連結ロッド１２に作用する。 The loom M shown in FIG. 1 consists of several heddle frames, only one of which can be seen by reference numeral 1 in this figure. The various frames of the loom M are actuated by the longitudinal oscillating motion indicated by the double arrow F 1 and given by the cam mechanism 10, the output lever of which is interlocked with the bending lever 13 and by the connecting rod 14. Each acts on a connecting rod 12 which is integrally connected to the frame.

レバー１１はヘドルフレームの数に等しい数に設けられ、二重矢印Ｆ1 により示される如く、機構１０のフレーム１６により支持された共通カムの長手方向軸線Ｘ15を中心に揺動するように据え付けられている。この機構１０はさらに幾つかの適合カムから成り、各カムが二つの軌道１８Ａと１８Ｂを形成し、レバー１１により保持されたそれぞれローラ１９Ａと１９Ｂを軌道１８Ａと１８Ｂに押圧する。 The levers 11 are provided in a number equal to the number of heddle frames and swing around the longitudinal axis X 15 of the common cam supported by the frame 16 of the mechanism 10 as indicated by the double arrow F 1. It is installed. The mechanism 10 further comprises several matching cams, each cam forming two tracks 18A and 18B, which press the rollers 19A and 19B held by the lever 11 against the tracks 18A and 18B, respectively.

カム１８はフレーム１６により支持される共通軸２０に取り付けら、軸の第一端２０Ａがベベルピニオン２２と交差するように設計され且つ軸２０をその長手方向軸線Ｘ20を中心に駆動させ得る減速歯車を形成するベベル歯車を保持する。 Cam 18 deceleration mounting et a common axis 20 supported by the frame 16, may be driven mainly its longitudinal axis X 20 of the designed and shaft 20 as the first end 20A of the shaft intersects the bevel pinion 22 Holds the bevel gear that forms the gear.

軸２０とカム１８を支持するために、フレーム１６は円形断面の二つのオリフィス１６Ａと１６Ｂにより貫通されて、それらそれぞれ中央軸線が全体に互いに整合されて、軸２０がフレーム１６の適切な場所にあるときに軸線Ｘ20と整合される。このオリフィス１６Ａと１６Ｂはそれぞれに中間リブ１６Ｃに、単片であるフレーム１６の側面１６Ｄに形成される。 To support the shaft 20 and cam 18, the frame 16 is penetrated by two orifices 16A and 16B of circular cross-section, each of which has a central axis aligned with each other so that the shaft 20 is in place in the frame 16. It is aligned with the axis X 20 to a certain time. The orifices 16A and 16B are respectively formed on the intermediate rib 16C and on the side surface 16D of the frame 16 which is a single piece.

軸受２３はオリフィス１６Ａに置かれ、リブ１６Ｃのいずれかの側面に延びる軸２０を支持できる。オリフィス１６Ａから、軸２０はオリフィス１６Ａと１６Ｂの間の距離Ｄ16、即ちフレーム１６の部品１６Ｃと１６Ｄの対向面の間の距離より厳密に少ない長さＬ20にわたりオリフィス１６Ｂの方向に延びる。これは距離Ｄ16と長さＬ20の間の差に等しい幅ｌE により図３に影に示された空間Ｅを形成する。 The bearing 23 is placed in the orifice 16A and can support the shaft 20 extending on either side of the rib 16C. From the orifice 16A, the shaft 20 extends in the direction of the orifice 16B over the orifice 16A and 16B distance D 16, i.e. the frame 16 of the component 16C and 16D strictly less length L 20 than the distance between the opposing surfaces of between. This forms a space E, which is shaded in FIG. 3, with a width l E equal to the difference between the distance D 16 and the length L 20 .

空間Ｅは、幅ｌE がカム１８の幅ｌ18より大きいので、軸２０にカム１８を据え付けるために使用され得る。特に図３に示されるように、カム１８は矢印Ｆ3 の方向に、即ち軸線Ｘ20に全体に垂直な方向に空間Ｅへ挿入され得て、このカム１８はフレーム１６の側面１６Ｄと軸２０の自由端２０Ｂの間に挿入される。カム１８の中央孔１８Ｃが全体に軸線Ｘ20と整合されるときに、図３の矢印Ｆ4 の方向に、即ちリブ１６Ｃの方向にこのカムを移動できるので、このカムは軸２０の端２０Ｂを取り囲む。次に、このために設けられたカムの軸方向ドリル孔を整合させるようにカムを角度的に配向することができ、角度割出しロッド２４が軸２０に既に据え付けられたカムの対応整合オリフィスに前もって据付けられている。 The space E can be used to mount the cam 18 on the shaft 20 because the width l E is greater than the width l 18 of the cam 18. In particular, as shown in FIG. 3, the cam 18 in the direction of arrow F 3, that is, in a direction perpendicular to the entire axis X 20 could be inserted into the space E, the side surface 16D and the shaft 20 of the cam 18 the frame 16 Between the free ends 20B. When the central hole 18C of the cam 18 is aligned with the axis X 20 across the direction of the arrow F 4 in FIG. 3, i.e. it is possible to move this cam in the direction of the ribs 16C, the end 20B of the cam shaft 20 Surrounding. The cam can then be angularly oriented to align the axial drill hole of the cam provided for this purpose, with the angle indexing rod 24 being fitted into the corresponding alignment orifice of the cam already installed on the shaft 20. It has been installed in advance.

機構１０に設けられたすべてのカムは上記に示されるように、軸２０に据付けられたならば、軸２０の端２０Ｂはそれぞれに軸２０と側面１６Ｄにしっかりと取り付けられた端片部材４０とスリーブ５０によってフレーム１６の側面１６Ｄに連結されている。端片部材４０はオリフィス１６Ｂの方向に軸２０を延ばすように設計されて、軸２０の端２０Ｂに設けられたほぞ２０Ｃと交差するように設計されたみぞ４０Ｃを備えており、互いに回転するように要素２０と４０を速く形成でき、それで、軸２０により端片部材４０の角度駆動を固定させる。   If all the cams provided in the mechanism 10 are installed on the shaft 20, as shown above, the ends 20B of the shaft 20 are respectively connected to the end pieces 40 which are firmly attached to the shaft 20 and the side surface 16D. The sleeve 50 is connected to the side surface 16D of the frame 16. The end piece member 40 is designed to extend the shaft 20 in the direction of the orifice 16B, and is provided with a groove 40C designed to intersect the tenon 20C provided at the end 20B of the shaft 20 so as to rotate with each other. The elements 20 and 40 can be formed quickly, so that the angular drive of the end piece member 40 is fixed by the shaft 20.

この端片部材４０は軸２０の端２０Ｂを取り囲み且つこの端８に最も近いカム１８に押圧するように設計されたスカート４０Ｄから成り、その押圧の間にカムの堆積部に矢印Ｆ5 により表現され且つ軸２０に据え付けらて肩を形成するリング２５へ向けられた力を働かす。この力は握り効果によりカムが回転することを阻止する。 The end piece member 40 is composed of a skirt 40D designed to push the cam 18 closest to and this end 8 surrounds the end 20B of the shaft 20, represented by arrow F 5 the deposition portion of the cam during the pressing Force applied to the ring 25 which is mounted on the shaft 20 and forms a shoulder. This force prevents the cam from rotating due to the grip effect.

この端片部材４０は端片部材４０のドリル孔４０Ｅに且つ軸２０のタッピング２０Ｅに受けられたねじ４１によって軸２０に固定されている。それで、ねじ４１を締め付けることにより、力Ｆ5 はカム１８を握って軸２０に回転するようにカムをしっかりと取り付けできるように作用される。 The end piece member 40 is fixed to the shaft 20 by a screw 41 received in the drill hole 40E of the end piece member 40 and the tapping 20E of the shaft 20. So, by tightening the screw 41, the force F 5 is operative to be mounted firmly on the cam to rotate the shaft 20 holds the cam 18.

スリーブ５０は四本のねじ５１によってフレーム１６の側面１６Ｄに固定され、二本のねじは図２において見ることができ、オリフィス１６Ｂの外側に半径方向に位置したタッピングを貫通する。このスリーブ５０は側面１６Ｄの外面に押圧するリム５０Ａから成り、端片部材４０と軸２０の端端２０Ｂを取り囲むようにリブ１６Ｃの方向に延びている。一連のローラ６０は端片部材４０の半径方向外面４０Ｆとスリーブ５０の半径方向内面５０Ｆとの間に介入されて、それで端２０Ｄを支持する軸受を創ることができる。ねじ５０Ｊにより固定されたラグ５０Ｇはローラ６０を適切な位置に保持できる。   The sleeve 50 is secured to the side surface 16D of the frame 16 by four screws 51, the two screws visible in FIG. 2, passing through a tapping radially located outside the orifice 16B. The sleeve 50 includes a rim 50A that presses against the outer surface of the side surface 16D, and extends in the direction of the rib 16C so as to surround the end piece member 40 and the end 20B of the shaft 20. A series of rollers 60 can be interposed between the radially outer surface 40F of the end piece member 40 and the radially inner surface 50F of the sleeve 50, thereby creating a bearing that supports the end 20D. The lug 50G fixed by the screw 50J can hold the roller 60 in an appropriate position.

ストッパー５０Ｋはスリーブ５０の中央開口に分解自在に据え付けられて、端片部材４０とねじ４１を覆うことができる。   The stopper 50 </ b> K is removably installed in the central opening of the sleeve 50 and can cover the end piece member 40 and the screw 41.

それで、要素４０−６０は軸２０を延ばすことを可能とするので、その端がオリフィス１６Ｂで側面１６Ｄにより支持されている。   Thus, elements 40-60 allow shaft 20 to extend so that its ends are supported by side 16D with orifice 16B.

ローラ６０により形成された軸受が端片部材４０のスカート４０Ｄに必ずしも置かれずに、端片部材４０の長さの任意の位置に形成され得た。   The bearing formed by the roller 60 was not necessarily placed on the skirt 40D of the end piece member 40, and could be formed at an arbitrary position of the length of the end piece member 40.

カム機構が分解される、特にあるカムを交換する必要があるならば、再び空間Ｅを創るためにストッパー５０Ｋを取り外し、次にねじ５１と４１を緩めて要素４０と５０を取り外すのに十分であり、その空間によりカム１８が上記の移動の逆である移動において取り外され得る；次に新たなカムが据え付けられ得る。   If the cam mechanism is disassembled, especially if it is necessary to replace a cam, it is sufficient to remove the stopper 50K to create space E again and then loosen the screws 51 and 41 to remove the elements 40 and 50. Yes, the space allows the cam 18 to be removed in a movement that is the reverse of the above movement; a new cam can then be installed.

図４に示されたこの発明の第二実施態様では、軸２０を延ばす端片部材４０は孔１６Ｂの内側まで延びていて、そこで介入されたローラ６０から創られた軸受を受けている。ねじ４１は端片部材４０を軸２０の端２０Ｂにしっかりと取り付けることを可能とし、この端片部材４０は座金７０と連動され、その座金はカム１８にカムを握ってカムを回転可能にしっかりと取り付ける軸方向力Ｆ5 を働かすことを可能とする。 In the second embodiment of the invention shown in FIG. 4, the end piece member 40 extending the shaft 20 extends to the inside of the bore 16B and receives a bearing created from the roller 60 interposed there. The screw 41 enables the end piece member 40 to be firmly attached to the end 20B of the shaft 20, and this end piece member 40 is interlocked with a washer 70, and the washer grips the cam on the cam 18 so that the cam can rotate. It is possible to apply the axial force F 5 to be attached.

ストッパー５０Ｋは端片部材４０とねじ４１を外部から隔離することを可能にする。   The stopper 50K makes it possible to isolate the end piece member 40 and the screw 41 from the outside.

第二実施態様では、空間Ｅはカム１８が必要に応じて据え付け取り外しされ得るように創られる。   In the second embodiment, the space E is created so that the cam 18 can be installed and removed as required.

前記種々の実施態様の特徴は、この発明の内容に組合せられ得る。   The features of the various embodiments can be combined with the content of the invention.
