本考案はとくにエアージエツトルーム、ウオー
タージエツトルーム等に超高速織機に適する綜絖
枠に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a heald frame suitable for ultra-high speed looms, particularly for air jet rooms, water jet rooms, etc.
織機の綜絖枠は、上下のヘルドバーと、左右の
サイドステーとが結合されて額縁状に構成され
る。
The heald frame of a loom is constructed in the shape of a picture frame by connecting upper and lower heald bars and left and right side stays.
従来、このヘルドバーとサイドステーの結合構
造として、サイドステーにヘルドバー側に向けて
連結部を一体に突設し、この連結部をヘルドバー
の端部内に嵌合させて複数本のリベツト等にて固
定している。したがつて、ヘルドバーとサイドス
テーとは剛体的に結合されている。 Conventionally, the coupling structure of this heald bar and side stay was such that a connecting part was integrally provided on the side stay to protrude toward the heald bar, and this connecting part was fitted into the end of the heald bar and fixed with multiple rivets, etc. are doing. Therefore, the heald bar and the side stay are rigidly connected.
一方、近時において織機の高速化が進む中、織
物の高品質を維持するために、高速運転下でも、
ヘルドの開口運動が綜絖枠全幅に亘つて均一に行
なわれることがが求められる。そこで最近では、
ヘルドバーの剛性を高め、綜絖枠の上下運動に伴
う慣性力によるヘルドバーの撓みを防止して開口
運動の全幅均一性を保持することとしている。 On the other hand, as looms have become faster in recent years, in order to maintain the high quality of textiles, even under high-speed operation,
It is required that the shedding movement of the heald be performed uniformly over the entire width of the heald frame. So recently,
The rigidity of the heald bar is increased to prevent deflection of the heald bar due to inertia caused by vertical movement of the heald frame, thereby maintaining uniformity of shedding movement across the entire width.
ところが、綜絖枠の左右両側が別々のロープを
介して開口装置に連結される所謂消極開口方式の
場合、ロープの伸び、縮み等によつて左右両側の
上下運動の同期が崩れる場合が多々ある。
However, in the case of the so-called negative shedding method in which the left and right sides of the heald frame are connected to the shedding device via separate ropes, the vertical movements of the left and right sides often become out of synchronization due to stretching or contraction of the ropes.
この場合、従来の綜絖枠によると、ヘルドバー
とサイドステーとが剛体的に結合され、しかもヘ
ルドバーが高剛性で撓まないことから、左右両側
の同期不調に伴い、結合部分に大応力が作用する
ため、この結合部分が破損する事故が起こつてい
た。また、ロープ寿命により片側のロープが破断
した場合も同様の事態が発生していた。 In this case, according to the conventional heald frame, the heald bar and the side stay are rigidly connected, and since the heald bar is highly rigid and does not bend, large stress is applied to the joint part due to synchronization on both the left and right sides. As a result, accidents have occurred in which this joint has been damaged. A similar situation also occurs when one rope breaks due to rope life.
ところで、低速織機において、ヘルドバーが撓
むことを前提として、この撓み時に結合部分に大
応力が作用しないように、、サイドステーに突設
した連結部を、ヘルドバーの端部内に嵌入して、
前後方向水平軸まわりに相対回動可能にピン連結
したものが実公昭61−26385号公報によつて公知
となつている。 By the way, in a low-speed loom, assuming that the heald bar is bent, in order to prevent large stress from acting on the joint part during this bending, the connecting part protruding from the side stay is inserted into the end of the heald bar.
A device which is connected by a pin so as to be relatively rotatable around a horizontal axis in the front-rear direction is known from Japanese Utility Model Publication No. 61-26385.
この公知構成によると、ヘルドバーの撓み時だ
けでなく、左右の同期不調時または片側ロープ破
断時においても、ヘルドバーとサイドステーとの
間の相対回動によつて、結合部分に大応力が作用
することを防止することができる。 According to this known configuration, large stress is applied to the joint portion due to the relative rotation between the heald bar and the side stay, not only when the heald bar is deflected, but also when left and right synchronization is out of order or when one rope breaks. This can be prevented.
しかし、この公知構成によると、つぎのような
欠点があつた。 However, this known configuration has the following drawbacks.
(イ) ヘルドバーとサイドステーを相対回動可能に
結合する結果、結合部分への大応力作用時以外

た、製織運転中に、僅かな応力によつてもヘル
ドバーとサイドステーとの間に不必要な相対回
動運動が生じ、開口運動に悪影響を与え、高品
質の織物が製織できなくなる。(b) As a result of connecting the heald bar and the side stay so that they can rotate relative to each other, they rotate relative to each other even when large stress is applied to the joint, making it impossible to maintain the perpendicular state between the two. For this reason, when assembling the heald frame into a loom, it becomes difficult to adjust the level of each heald frame, which causes problems in the assembling work. Further, during weaving operation, even a slight stress causes unnecessary relative rotational movement between the heald bar and the side stay, which adversely affects the shedding movement and makes it impossible to weave high-quality fabrics.
(ロ) サイドステーの連結部が、ヘルドバーの中空

直接ピン結合され、しかも綜絖枠の軽量化の要

の発生、ピン連結部分の破損が起こり、耐久性
に劣るものとなる。(b) The connecting part of the side stay is directly pin-coupled to the thin-walled heald bar itself in the hollow part of the heald bar, and in addition, in order to reduce the weight of the heald frame, the heald bar is made of a lightweight material with poor abrasion resistance. Therefore, when applied to ultra-high-speed looms, the pin connecting parts are likely to wear rapidly and rattle early, resulting in loud noise and damage to the pin connecting parts, resulting in poor durability. becomes.

きる織機の綜絖枠を提供するものである。 Therefore, the present invention can reliably prevent damage to the joint between the side stay and the heald bar due to synchronization of the left and right vertical movements, etc., and can also prevent rattling of the pin joint, increasing durability. To provide a heald frame for a loom that can ensure a perpendicular state of a heald bar and a side stay except when a large stress is applied.

In the present invention, at each joint between the upper and lower heald bars and the left and right side stays, connecting portions are provided sideways on both the heald bar and the side stays, and these connecting portions are rotated relative to each other around a horizontal axis in the longitudinal direction. The heald bar and the side stay are movably connected, and a spring is provided between the two connecting parts to exert a spring force in the direction of maintaining the heald bar and the side stay at right angles against the relative rotational force of the two connecting parts. be.

With this configuration, the basic function is that when a left-right synchronization failure of vertical movement occurs, the relative rotational movement between the heald bar and the side stay is
It can absorb large stresses acting on the joint. Furthermore, since the two are connected to each other so as to be relatively rotatable outside the heald bar, the connecting portion on the heald bar side can have sufficient wear resistance strength, thereby preventing the connecting portion from wobbling. Further, except when a large stress is applied to the connecting portion, the spring provided between the two connecting portions can ensure the perpendicular state of the side stay and the heald bar.
本考案の実施例を図によつて説明する。 An embodiment of the present invention will be described with reference to the drawings.
第１図乃至第４図に本考案の基本実施例を示し
ている。 A basic embodiment of the present invention is shown in FIGS. 1 to 4.
図では、左サイドステー１と上部ヘルドバー２
の結合部分のみを示しているが、、他の三個所
（左サイドステー１と下部ヘルドバー、右サイド
ステーと上下のヘルドバー）の結合部分について
も以下同様に構成される。 In the figure, left side stay 1 and upper heald bar 2
Although only the connecting portion is shown, the connecting portions at the other three locations (the left side stay 1 and the lower heald bar, and the right side stay and the upper and lower heald bars) are constructed in the same manner.
サイドステー１には、従来同様、板状の連結部
（以下、ステー側連結部という）１１がヘルドバ
ー側に向けて一体に突設されている。 The side stay 1 is provided with a plate-shaped connecting portion (hereinafter referred to as a stay-side connecting portion) 11 integrally projecting toward the heald bar side, as in the conventional art.

る。 On the other hand, a connector 3 is attached to the end of the heald bar 2 that is coupled to the side stay 1. This connector 3 has a clevis-like connector (hereinafter referred to as a bar-side connector) that can be engaged with the stay-side connector 11.
31, and a mounting part 32 for the heald bar 2, with the bar side connecting part 31 protruding outside the heald bar 2 toward the side stay side.
2 is fitted inside the end of the heald bar 2 and fixed with push bolts 4, 4. The push bolts 4, 4 are screwed into a female threaded member 5 inserted into the upper part of the heald bar 2, and their tips are attached to the mounting portion 32.
is fixed inside the heald bar 2 by pressing from above.
なお、この押しボルト４，４による固定方式に
代えて、リベツト止め方式を採用してもよい。 Note that instead of the fixing method using the push bolts 4, 4, a riveting method may be adopted.

る。 Corresponding connecting holes 11a, 31a are provided in both the stay-side and bar-side connecting portions 11, 31, and the connecting portions 11, 31 are provided with corresponding connecting holes 11a, 31a.
1 and 31 are connected by a pin (rivet) 6 so as to be relatively rotatable around a horizontal axis in the front-rear direction (caulked connection). 7 is a bushing fitted onto the pin 6.

ができる。 In this way, both the stay side and bar side connecting parts 11,
31 are connected with pins so that they can rotate relative to each other, so that when a large stress is applied to the joint between the side stay 1 and the heald bar 2 due to an imbalance in left-right synchronization of vertical movement, both the connecting parts 11a and 31a Since they rotate relative to each other to absorb stress, no unreasonable force is applied to the joint, and damage to the joint can be reliably prevented.

連結する従来の場合のようなピン連結部分ガタつ
きが発生せず、耐久性に富むものとなる。 Moreover, since the connecting tool 3 is fixed to the heald bar 2 and the connecting part 31 of this connecting tool 3 and the stay side connecting part 11 are connected with a pin outside the heald bar 2, the connecting tool 3 is fixed to the heald bar 2.
In addition, it is possible to use a material with high wear resistance such as lost wax cast steel or stainless steel other than the heald bar 2. Therefore, the pin connection portion does not rattle as in the conventional case where the stay side connection portion is directly connected to the heald bar in the hollow portion of the heald bar, and the pin connection portion is highly durable.
ただし、上記構成のみでは、結合部への大応力
作用時以外にも、両連結部１１，３１が相対回動
してしまい、サイドステー１とヘルドバー２の直
角状態が維持できなくなるという弊害が生じる。 However, with only the above configuration, both the connecting parts 11 and 31 will rotate relative to each other even when large stress is applied to the joint part, and the side stay 1 and the heald bar 2 will not be able to maintain the perpendicular state. .
そこで、この点の対策として、両連結部１１，
３１間にコ字形の板バネ８が設けられている。 Therefore, as a countermeasure for this point, both connecting portions 11,
A U-shaped leaf spring 8 is provided between 31 and 31.
この板バネ８は、上下の水平辺部８１，８１が

バネ力を発揮する。 This leaf spring 8 has upper and lower horizontal sides 81, 81 in contact with the stay side connecting part 11 from the outside,
The vertical side portion 82 is attached to the back wall of the bar-side connecting portion 31 with screws 9, 9, and exerts a spring force in the direction of maintaining the two connecting portions 11, 31 at right angles against the relative rotational force of the two connecting portions 11, 31. .

おそれがなくなる。 Due to the right angle holding action of the leaf spring 8, the side stay 1 and the heald bar 2 are maintained at right angles except when a large stress is applied to the joint portion, and there is no possibility that this right angle state will collapse due to a slight stress. Therefore, the level adjustment of each heald frame when the heald frame is assembled into a loom can be performed in the same way as when the side stay 1 and heald bar 2 are rigidly connected. Furthermore, there is no possibility that the heald frame may be deformed during normal weaving operations and adversely affect shedding motion.
