工条件を数多く変えながらその適正条件を追究してゆく
のが通常の探索方法である。Generally, in the development of new false-twisted yarns of synthetic fibers, the usual search method is to pursue the appropriate conditions while changing many processing conditions.
その際、試験機として既設マシーンを用いた場合、各ロ
ーラ間の回転軸の連結はギアあるいはプーリによるもの
が多い。In this case, when an existing machine is used as a testing machine, the rotation shafts between each roller are often connected by gears or pulleys.
そのような従来のマシーンでは、各ローラ間の周速比の
変更はギアあるいはプーリの交換によらなければならず
、したがって作業が煩雑であり、また機械停止を強いら
れるため、糸条を走行させたままでの条件変更は不可能
であった。In such conventional machines, changing the circumferential speed ratio between each roller requires replacing gears or pulleys, which is cumbersome and requires the machine to stop. It was not possible to change the conditions as they were.
一方、それ以外の従来マシーンとして、各ローラの軸に
それぞれ変速機をつけたものもあるが、このようなマシ

とはできても、複数個のローラ間の各周速比を一定に保
ちながら、かつ系全体としての周速を連続的に変更する
ということはできなかった。On the other hand, there are other conventional machines that have a transmission attached to each roller shaft, but in such a machine, although it is possible to change the circumferential speed ratio between each roller independently, it is possible to change the circumferential speed ratio between each roller independently. It has not been possible to continuously change the circumferential speed of the entire system while keeping the circumferential speed ratio between the rollers constant.
本考案の目的は、このような従来の延伸仮撚装置の欠点
を克服し、糸条を走行させたままで連続的かつ広範囲に

ることを特徴とするものである。To achieve this object, the present invention is a drawing false twisting device having a plurality of yarn running rollers, in which the axis S of the draw roller 2 is
All the rollers 1, 3, and 4 of the remaining yarn traveling rollers whose conditions need to be changed are connected to the drive main shaft S' which is directly connected to the motor M1 with two attached to the first transmission without going through the transmission. ．．
5 axes are each connected to a transmission Kl different from the first transmission.
, to 3. 41 and 5 are connected to the driving main shaft.
以下、図によって本考案を具体的に説明する。Hereinafter, the present invention will be specifically explained with reference to the drawings.
第１図は、本考案の一実施例よりなる延伸仮撚装置の概
略構成図である。FIG. 1 is a schematic diagram of a drawing false twisting device according to an embodiment of the present invention.

Y is supplied from feed roller 1;
While being stretched to a predetermined magnification between and the draw roller 2,
False twisting and heat setting are performed by the first heater H1 and false twisting device T.
さらに、第１テ゛リバリーローラ３によって糸条の走行
方向を変えられたあと、第２ヒータＨ２によつて再び熱
固定され、第２テ゛リバリーローラ４を経て巻取ローラ
５に、まきとられる。Furthermore, after the running direction of the yarn is changed by the first yarn delivery roller 3, it is heat-fixed again by the second heater H2, and is wound onto the take-up roller 5 via the second yarn delivery roller 4.
なお、本考案でいう巻取ローラとは、巻取速度を規定す

上記実施例においては、未延伸糸条を延伸しながら同時
に仮撚加工する場合について示したが、フィードローラ
の後に第１ドローローラを設け、この間で実質的に延伸
をほどこした後、連続的に仮撚加工する場合についても
、同様に本考案装置を用いることがで゛きる。In the above example, the case where the undrawn yarn is stretched and false twisted at the same time is shown, but a first draw roller is provided after the feed roller, and after the drawing is substantially performed between these rollers, the The device of the present invention can be similarly used in the case of false twisting.
また上記実施例では、延伸仮撚をほどこした後、さらに
第２ヒータによって熱固定している（いわゆる仮撚モチ
゛イファイ加工）が、第２ヒータを通さずに仮撚加工す
るだけのことも、もちろん可能である。Furthermore, in the above embodiment, after the stretching and false twisting, heat setting is performed using the second heater (so-called false twisting stiffening processing), but it is also possible to simply perform the false twisting process without passing through the second heater. It is possible.
仮撚装置としてはスピンドル仮撚装置、摩擦仮撚装置等
を用いることができる。As the false twisting device, a spindle false twisting device, a friction false twisting device, etc. can be used.
第２図は、第１図における延伸仮撚装置の駆動系統図で
ある。FIG. 2 is a drive system diagram of the drawing false twisting device in FIG. 1.

バリ−ローラ３・第２テ゛リバリーローラ４および巻取
ローラ５は、それぞれ変速機に、、に３．に４およびに
５を介して、タイミングベルトＢによって駆動主軸Ｓ′
に連結されている。As shown in FIG. 2, the shaft S of the draw roller 2 is connected to a driving main shaft S' which is directly connected to a motor M1 with two transmissions without going through the transmission. The roller 3, the second delivery roller 4 and the take-up roller 5 are connected to a transmission, respectively. 4 and 5, the driving main shaft S' is driven by the timing belt B.
is connected to.
また、仮撚装置Ｔは、上記ローラの駆動系統とは別に、
変速機に６付モ一タＭ２によって駆動される。In addition, the false twisting device T includes, in addition to the drive system of the rollers,
It is driven by a motor M2 with six gearboxes.

直後のドローローラの軸を駆動主軸に直結させれば系全
体の仮撚加工速度の調速が容易に行なえることの理由に
よる。In the present invention, the axis of the draw roller immediately after the false twisting device was selected as the axis to be directly connected to the drive main shaft, but this is because the overfeed rate of the false twisting zone, when changing the false twisting conditions,
When individually changing the stretching ratio in the stretching zone, the overfeed rate in the stiffening zone, and the relaxation rate in the winding zone, it is possible to minimize the It is possible to change the conditions by the operation of , and it is also possible to change the conditions while false-twisting the yarn.Furthermore, since the false-twisting speed is generally based on the draw roller speed immediately after the false-twisting device, the false-twisting This is because if the shaft of the draw roller immediately after the device is directly connected to the drive main shaft, the false twisting speed of the entire system can be easily controlled.
このような構成によりなる本考案の装置において、ドロ
ーローラとフィードローラ（あるいは第１ドローローラ
）との周速差を変速機に１でまたドローローラと巻取ロ
ーラとの周速差を変速機に５でそれぞれ必要なだけ調速
する（仮撚加工の場合）。In the device of the present invention having such a configuration, the difference in circumferential speed between the draw roller and the feed roller (or the first draw roller) is transmitted to the transmission, and the difference in circumferential speed between the draw roller and the take-up roller is transmitted to the transmission. and 5 to adjust the speed as required (in the case of false twisting).
さらに仮撚モディファイ加工の場合には、これらに加え
て、第１テ゛リバリーローラと第２テ゛リバリーローラ
との周速差を変速機に、、に４で、第２デリバリ−ロー
ラと巻取ローラとの周速差を変速機に４．に５でそれぞ
れ必要なだけ調速する。Furthermore, in the case of false twist modification processing, in addition to these, the difference in circumferential speed between the first and second delivery rollers is transmitted to the transmission, and the difference between the circumferential speeds between the second delivery roller and the take-up roller is 4. Use the circumferential speed difference in the transmission. and 5 to adjust the speed as necessary.
なお、ドローローラと第１デリバリ−ローラとは、通常
同一速度をとるか、０〜３％程度の固定的な速度差をと
るため、条件変更の必要がなければ、第１デリバノーロ
ーラは駆動主軸に直結してしまってもよい。Note that the draw roller and the first delivery roller usually have the same speed or a fixed speed difference of about 0 to 3%, so if there is no need to change the conditions, the first delivery roller will not be driven. It may be directly connected to the main shaft.
広汎かつ特殊な加工条件変更を前提とすれば、このロー
ラも変速機に３によって、調速可能とすることが好まし
い。Assuming extensive and special changes in processing conditions, it is preferable that the speed of this roller is also controlled by a transmission 3.
このようにして、各ローラ間の周速差は、各ローラの軸
にそれぞれ設けられた各変速機によって連続的に調速可
能である。In this way, the circumferential speed difference between each roller can be continuously controlled by each transmission provided on the shaft of each roller.
そして、系全体として周速を変更する場合には、駆動主
軸にとりつけた変速機に２（駆動モータに直結）によっ
て連続的に調速可能である。When changing the circumferential speed of the system as a whole, the speed can be continuously controlled by the transmission 2 (directly connected to the drive motor) attached to the drive main shaft.
このとき、すべてのローラの周速は同時に、かつ連続的
に変化するが、各ローラ間の周速比はいかなるときにも
規定の一定値を保っている。At this time, the circumferential speeds of all the rollers change simultaneously and continuously, but the circumferential speed ratio between the rollers remains constant at any time.
仮撚装置の駆動系はこれらとは別系になっているが、上
記ローラ系と同時あるいは別個に、連続的に調速可能で
ある。The drive system of the false twisting device is separate from these systems, but can be continuously controlled at the same time as or separately from the roller system.
本考案の延伸仮撚装置は、いかなる合成繊維にも適用可
能であるが、特に従来は糸掛けが困難とされていたポリ
ウレタン弾性糸とポリアミド繊維との合糸仮撚にはとり
わけ好適である。Although the drawing false twisting device of the present invention can be applied to any synthetic fiber, it is particularly suitable for false twisting a composite yarn of polyurethane elastic yarn and polyamide fiber, which has been difficult to thread in the past.
すなわち、本考案の装置を用いれば、低速にて糸掛はス
タート後、規定周速まで糸を掛けたままで連続的に徐々
に増速することができる。That is, by using the device of the present invention, threading can be started at a low speed and then the speed can be gradually increased continuously while the thread is being threaded up to a specified circumferential speed.
このとき、各ローラ間の周速比は設定値を一定に保って
いる。At this time, the circumferential speed ratio between each roller is kept constant at a set value.

撚を、糸掛は容易にがつ安定しておこなうことができる
。By increasing the rotation of the provisional conveyance device in accordance with the yarn speed at the same time as driving the rollers stably, we are now able to use polyurethane elastic yarn, which was conventionally wound due to its high friction coefficient and low Young's modulus, and which was prone to yarn breakage. False twisting of yarns with polyamide fibers can be easily and stably performed.

に変更が可能となり、また多くの条件変更をおこなう場
合にも、短時間で広範囲に変更が可能となる。Furthermore, if you want to arbitrarily change the specified processing conditions for any yarn, the device of this invention allows you to easily change them while the yarn is running without stopping the machine. Therefore, even when changing many conditions, it is possible to make a wide range of changes in a short period of time.
