Description

本発明は、請求項１の上位概念に記載の形式の、繊維機械におけるドラフト機構の配置構造に関する。   The present invention relates to an arrangement structure of a draft mechanism in a textile machine of the type described in the superordinate concept of claim 1.

ドイツ連邦共和国実用新案登録第１９７１９２９号明細書から、請求項１の上位概念に記載の形式のドラフト機構の配置構造が公知である。各機械側の、互いに向き合う支持体は、それぞれ水平方向で延びるホルダロッドに取り付けられて、ホルダロッドに対して平行に、支持体の間に配置されたブリッジによって相互結合される。比較的高い安定性を得るために、両方の支持体は、追加的にブリッジに対して平行な、支持体の間に配置されたウェブによって結合される。   From the German utility model registration No. 1971929, the arrangement structure of the draft mechanism of the type described in the superordinate concept of claim 1 is known. Supports facing each other on each machine side are attached to holder rods extending in the horizontal direction, and are connected to each other by a bridge arranged between the supports in parallel to the holder rods. In order to obtain a relatively high stability, both supports are joined by a web arranged between the supports, additionally parallel to the bridge.

この場合の欠点によれば、このようなドラフト機構の装備および装備変更は極めて面倒である。なぜならば先ず支持体は、ホルダロッドに対して調整して、次いで支持体に被せ嵌められたキャリアをホルダロッドに対して調整する必要があるという理由による。   According to the drawbacks in this case, the equipment and equipment changes of such a draft mechanism are extremely troublesome. This is because the support first needs to be adjusted with respect to the holder rod, and then the carrier fitted over the support needs to be adjusted with respect to the holder rod.

したがって本発明の課題は、繊維機械におけるドラフト機構を使用する際の融通性を高めて、特に繊維機械の装備に関する手間を低減することである。   Accordingly, an object of the present invention is to increase flexibility when using a draft mechanism in a textile machine, and in particular, to reduce labor related to the equipment of the textile machine.

この課題は、請求項１の特徴部に記載の構成によって解決された。   This problem has been solved by the configuration described in the characterizing portion of claim 1.

本発明の有利な実施形態は、従属請求項の対象である。   Advantageous embodiments of the invention are the subject of the dependent claims.

請求項１の構成によれば、支持体が、少なくとも１つのホルダロッドに対して平行な軸線を中心に旋回可能に相互結合されている。これによって、繊維機械の少なくとも１つのホルダロッドに支持体を取り付けるために、支持体は、互いに旋回することができ、支持体に配置されたキャリアを備えた、相互結合された支持体は、先ず少なくとも１つのホルダロッドに被せ嵌めて、同時にドラフト機構の、対応するボトムローラに対して調整することができる。この場合個々の支持体の落下はもはや生じず、もしくはキャリアが支持体によって少なくとも１つのホルダロッドに取り付けられるまえに、キャリアを調整するために、ホルダロッドに各支持体を一時的に取り付けるための追加的な補助手段は不要となる。したがって装備コストが削減される。なぜならば最初の組立および装備変更に際して掛かる時間が短縮されるからである。   According to the first aspect of the present invention, the supports are interconnected so as to be pivotable about an axis parallel to the at least one holder rod. Thereby, in order to attach the support to at least one holder rod of the textile machine, the supports can swivel together, and the interconnected support with the carrier arranged on the support is first of all It can be fitted over at least one holder rod and adjusted simultaneously with the corresponding bottom roller of the drafting mechanism. In this case, the individual supports no longer fall or for temporarily attaching each support to the holder rod in order to adjust the carrier before the carrier is attached to the at least one holder rod by the support. Additional auxiliary means are not required. Therefore, the equipment cost is reduced. This is because the time required for initial assembly and equipment change is shortened.

有利には、向き合った支持体は、緊締スリーブによって結合することができ、緊締スリーブの長手軸線を中心に支持体は旋回可能である。支持体は、緊締スリーブによって、簡単かつ安価な形式で結合可能であり、これによって少なくとも１つのホルダロッドに被せ嵌める際の操作が簡略化される。   Advantageously, the opposed supports can be joined by a clamping sleeve, the support being pivotable about the longitudinal axis of the clamping sleeve. The support can be coupled in a simple and inexpensive manner by means of a clamping sleeve, which simplifies the operation when it is fitted over at least one holder rod.

このために支持体は、それぞれ接触面に対して垂直方向で延びる少なくとも１つの突出部を備えており、突出部は、ホルダロッドに対して平行の貫通孔を備えており、貫通孔は、緊締スリーブを収容するのに役立つ。支持体における少なくとも１つの突出部は以下のように形成されていて、すなわち突出部は、別の支持体の少なくとも１つの突出部と係合するように形成されており、これによって相互結合される両方の支持体の整合した配置構造が達成される。このようにするとホルダロッドに支持体を取り付ける際に、両方の支持体の接触面は互いに平行になり、支持体は互いに整合する。   For this purpose, the support body is provided with at least one protrusion that extends in a direction perpendicular to the contact surface, the protrusion has a through hole parallel to the holder rod, and the through hole is tightened. Helps accommodate the sleeve. At least one protrusion in the support is formed as follows: the protrusion is formed to engage with at least one protrusion of another support and is thereby interconnected. A consistent arrangement of both supports is achieved. In this way, when attaching the support to the holder rod, the contact surfaces of both supports are parallel to each other and the supports are aligned with each other.

有利には、貫通孔の中心点は、各接触面に対して幾分か引っ込めることができる。ホルダロッドに支持体を固定する際に、つまり支持体の凹部がホルダロッドを包囲して、接触面が互いに接触する場合、貫通孔は、幾分か外向きに移動し、これによって緊締スリーブはクランプされて、変形される。それゆえプレロードが形成され、これによってホルダロッドにおける支持体の固定は改善される。   Advantageously, the center point of the through-hole can be somewhat retracted for each contact surface. When fixing the support to the holder rod, i.e. when the recess of the support surrounds the holder rod and the contact surfaces come into contact with each other, the through-holes move somewhat outwardly, so that the clamping sleeve Clamped and deformed. A preload is therefore formed, which improves the fixing of the support on the holder rod.

特に支持体は、同形に形成することができる。対向する支持体が同形に形成されていることによって、大量の生産数に基づいて、経済的な製造が達成され、したがって繊維機械の装備過程が簡単になり、取付に際して、緊締スリーブによって整合して相互結合するために、対応する構成を有する支持体が対を成して配置するよう考慮する必要はない。むしろ同形に形成された支持体は、少なくとも１つのホルダロッドに鏡像的に配置すればよく、これによって取付が簡単になる。   In particular, the support can be formed in the same shape. By forming the opposite supports in the same shape, economical production is achieved on the basis of a large number of productions, thus simplifying the installation process of the textile machine and aligning it with a clamping sleeve during installation. In order to be interconnected, it is not necessary to consider that supports having a corresponding configuration are arranged in pairs. Rather, the support formed in the same shape only needs to be mirror-imaged on at least one holder rod, which makes installation easier.

さらに少なくとも１つのホルダロッドは、多角形の横断面を有することができる。これによって支持体に設けられた収容部における形状結合（形状による束縛）式の配置構造が得られ、支持体は、少なくとも１つのホルダロッドに対して相対回動不能に配置されている。   Furthermore, the at least one holder rod can have a polygonal cross section. As a result, an arrangement structure of a shape coupling (constraint by shape) type in the accommodating portion provided in the support is obtained, and the support is arranged so as not to be rotatable relative to at least one holder rod.

選択的に鏡像的に配置された支持体を固定するために、互いに平行に配置された２つのホルダロッドを設けてもよい。したがってホルダロッドは、円形の横断面を有してよい。このようなホルダロッドは、簡単な幾何学横断面形状に基づいて安価に製造可能である。
以下に図面につき、本発明の実施例を詳しく説明する。 Two holder rods arranged in parallel to each other may be provided for fixing the selectively mirror-supported support. The holder rod may thus have a circular cross section. Such a holder rod can be manufactured inexpensively based on a simple geometric cross-sectional shape.
In the following, embodiments of the present invention will be described in detail with reference to the drawings.

図１には、図示していないドラフト機構の２つの支持体１を示しており、支持体１は、繊維機械の、図示していない機械架台の、互いに平行に配置された２つのホルダロッド６に取り付けるのに役立つ。支持体１は、それぞれキャリア２を備えており、キャリア２は、支持体１に、支承軸線を中心として旋回可能に配置されている。キャリア２は、図示していないトップローラを収容するのに役立ち、トップローラは、各ドラフト機構の、図示していない対応するボトムローラと協働して、糸を延伸させるために用いられる。   FIG. 1 shows two supports 1 of a draft mechanism (not shown), which are two holder rods 6 arranged parallel to each other on a machine stand (not shown) of a textile machine. Help to attach to. Each support body 1 includes a carrier 2, and the carrier 2 is disposed on the support body 1 so as to be rotatable about a support axis. The carrier 2 serves to accommodate a top roller (not shown), which is used to draw the yarn in cooperation with a corresponding bottom roller (not shown) of each drafting mechanism.

図１には、支持体１は、ホルダロッド６に被せ嵌め可能な位置で示した。このために支持体１は、対向して配置されていて、互いに向き合う端部で、緊締スリーブ４によって、図２に示したように、緊締スリーブ４の長手軸線を中心に旋回可能に結合される。支持体１は、キャリア２とは反対側で、互いに平行な２つの突出部７を備えており、突出部７は、緊締スリーブ４を収容するための、ホルダロッド６に対して平行な貫通孔１０を備えている。両方の支持体１を結合するために、各突出部７は、互いにオーバーラップして配置されており、各貫通孔１０が水平方向でみて整合するので、緊締スリーブ４は、貫通孔１０を通って挿入することができる。   In FIG. 1, the support 1 is shown at a position where it can be fitted over the holder rod 6. For this purpose, the support body 1 is arranged so as to be opposed to each other, and at the end portions facing each other, as shown in FIG. 2, the support body 1 is pivotably coupled around the longitudinal axis of the tightening sleeve 4. . The support 1 includes two protrusions 7 parallel to each other on the side opposite to the carrier 2, and the protrusions 7 are through-holes parallel to the holder rod 6 for receiving the tightening sleeve 4. 10 is provided. In order to connect both supports 1, the protrusions 7 are arranged so as to overlap each other, and the through holes 10 are aligned in the horizontal direction, so that the tightening sleeve 4 passes through the through holes 10. Can be inserted.

さらに突出部７の下方で、支持体１の接触面５にそれぞれ２つの凹部３が配置されている。凹部３は、その形状および寸法でホルダロッド６に対応しているので、ホルダロッド６は、支持体１の固定姿勢で、凹部３に収容されている。凹部３の配置構造は、支持体１の固定姿勢でホルダロッド６に対して同軸的である。支持体１の各突出部７の貫通孔１０は、接触面５に対して幾分か後退されているので、支持体１の凹部３がホルダロッド６を包囲して、支持体１の接触面が接触する場合、貫通孔１０の中心点は、水平方向でみて互いに変位しており、その結果貫通孔１０が緊締スリーブ４を変形する。   Further, two recesses 3 are arranged on the contact surface 5 of the support 1 below the protrusion 7. Since the recess 3 corresponds to the holder rod 6 in its shape and size, the holder rod 6 is accommodated in the recess 3 in a fixed posture of the support 1. The arrangement structure of the recesses 3 is coaxial with the holder rod 6 in the fixed posture of the support 1. Since the through hole 10 of each protrusion 7 of the support 1 is somewhat retracted with respect to the contact surface 5, the recess 3 of the support 1 surrounds the holder rod 6, and the contact surface of the support 1. , The center points of the through holes 10 are displaced from each other when viewed in the horizontal direction, and as a result, the through holes 10 deform the tightening sleeve 4.

緊締スリーブ４の変形によって、支持体１をホルダロッド６にクランプする際にプレロードが形成される。   Due to the deformation of the clamping sleeve 4, a preload is formed when the support 1 is clamped to the holder rod 6.

図３には、ホルダロッド６に固定された位置で支持体１を示した。このために支持体１は、緊締スリーブ４の長手軸線を中心に互いに接近するように旋回されるので、接触面５は互いに接触して、支持体１は互いに整合して配置される。支持体１を結合して固定するために、結合手段が設けられており、結合手段は、支持体１の、突出部７とは反対側に配置されている。   In FIG. 3, the support 1 is shown at a position fixed to the holder rod 6. For this purpose, the support 1 is pivoted so as to approach each other about the longitudinal axis of the clamping sleeve 4, so that the contact surfaces 5 are in contact with each other and the supports 1 are arranged in alignment with each other. In order to couple and fix the support 1, a coupling means is provided, and the coupling means is arranged on the opposite side of the support 1 from the protruding portion 7.

図４には、結合手段の配置構造を示した。結合手段は、ねじ８とナット９とを備えており、ナット９は、有利にはプッシュナットとして形成されている。ねじ８およびナット９は、支持体１の側壁の間で、ホルダロッド６に対して横向きに、支持体１の、突出部７とは反対側に配置されている。   FIG. 4 shows the arrangement structure of the coupling means. The coupling means comprises a screw 8 and a nut 9, which is preferably formed as a push nut. The screw 8 and the nut 9 are disposed laterally with respect to the holder rod 6 between the side walls of the support 1 and on the opposite side of the support 1 from the protrusion 7.
