Abstract

<P>PROBLEM TO BE SOLVED: To provide an apparatus highly performing operation, simply carrying out handling when repairing a weft yarn, slightly causing woven fabric defects related to a weft yarn in weft insertion of a jet loom and simply completing electrical connection during automatization and an apparatus for speeding up with energy saved as much as possible. <P>SOLUTION: The apparatus for measurement of length and storage of a rotary drum pooling method is subjected to synchronous ratio operation with an encoder mounted on a crank shaft of the loom by single motor driving to provide the weft insertion with free flight and restraint flight characteristics. Thereby, the defects related to the woven fabric in relation to the weft yarn are improved. In order to improve the handling, the weaving width is changed by varying the proportion of synchronous ratio. When the one weft yarn is required, the motor rotation is determined from the weaving width data to perform control by the number of pulses of the encoder for the motor. The need of a blower is eliminated by jetting air from a jetting nozzle only at the timing of winding the weft yarn onto a storage drum and air resistance during a weft insertion period is reduced. Thereby, the energy saving is achieved. The back tension of the weft insertion nozzle is reduced by reducing the air resistance during the weft insertion period. As a result, speedup of the jet loom can be carried out. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明はジェットルーム用よこ糸の測長貯留装置の性能向上に関する物である。
【0002】
【従来の技術】
従来の技術として貯留ドラムによこ入れ停止期間中よこ糸を巻き付けて置くロータリドラムプーリング方式。あらかじめドラム上によこ糸を巻いておき、必要長さをドラム径と解除回数で制御するフリードラムプーリング方式。公知例として、公開特許公報、昭60−71740等多数がある。又よこ入れに必要な長さのみ引き出す方法として、公開特許公報、特開平9−324344がある。1ピックの長さを連続で引き出し、よこ入れ停止期間、空気の流れで貯留する公知例としては公開特許公報、昭61−167048がある。
【0003】
【発明が解決しようとする課題】
ジェットルームにはウォータ式とエァー式がありウォータ式は比較的に織物の変更が少なく、測長貯留装置の機械的な機能部分が機械的に連結された、ロータリドラムプーリング方式、機械メーカの呼び方としてRDP、と呼ばれる測長貯留装置が多数採用されている、以後明細書の中ではロータリドラムプーリング方式をRDPと記す。エァー式は織物の変更やよこ糸補修が多く、フリードラムプーリング方式、機械メーカの呼び方としてFDP、と呼ばれる1ピックの長さ変更がドラム径の変更で行い、定常運転やよこ糸補修に必要な1ピックよこ入れを係止ピンの出し入れで行う電気式の測長貯留装置が主に使用されている、以後明細書の中ではフリードラムプーリング方式をFDPと記す。
【0004】
FDPは取り扱いが比較的に簡単であるが、最大の欠点は測長ドラムに数ピック分のよこ糸を貯留し、係止ピンで必要回数、よこ糸を解除するため、自由飛走のみで拘束飛走が無いことである。RDPは自由飛走と拘束飛走があり、よこ入れの時に糸に無理を与えない理想的なよこ入れ方法である。しかし機械的に機械本体と連結され、織物幅変更に必要な1ピックの長さ変更や、よこ糸の自動補修には不向きである。本発明の目的は自由飛走と拘束飛走とを持った、しかも1ピック長さ変更が簡単に出来、よこ糸補修の時に必要な1ピック長さのよこ糸を簡単に、送出可能な測長貯留装置である。
【0005】
もう1つRDPの欠点として、拘束飛走が完了して、貯留ドラムへよこ糸を巻き付け貯留するときのドラム巻き付け動機用に連続ブローが行われている。このブローによるよこ糸への抵抗により、よこ入れエネルギーが増大する。又ブロァーモータ容量は標準的に1セット0.75KWでロスが大きい。このよこ入れエネルギーとモータの省エネルギーも課題である。
【0006】
公知例の公開特許公報、特開平9−324344は駆動モータの性能が最近のジェットルーム回転数1000RPMに間欠運動として追随するのが困難で実用化していない。公開特許公報、昭61−167048はよこ入れ時によこ糸を貯留する風の流れがよこ入れの反対向きで、よこ入れのバックテンションが高く、よこ入れエネルギーが高くなり、最近使用されなくなった。
【0007】
【課題を解決する手段、作用】
RDPが持つ自由飛走と拘束飛走の特性を生かして、さらにFDPが持つ、使い安さの機能や省エネルギーを出すようにする。基本的にはRDPをACサーボモータで駆動し、このモータに付いているエンコーダとジェットルームのクランク軸に取り付けたエンコーダのパルス計算による同期比率運転により、機械的連結から電気的連結に変えることにより達成する。
【0008】
同期比率運転はジェットルームの回転と測長貯留装置が一定の割合で回転するもので、電気的に両者は連結されている、この割合は設定器で自由に変更でき、織物の幅が変更になったとき、この割合を変更して対応する。よこ糸補修などで、1ピックのよこ糸が必要な時は、同期比率運転は行わず、測長貯留装置を駆動するモータのエンコーダのパルス数を数えて回転量を制御する。
【0009】
設定器からは織物に必要な織り幅を入力すると、機械的なギヤー比やエンコーダ1回転のパルス数等を計算して、同期比率の割合が計算機で計算され、織機の運転と同時にドライバ、モータを、動作させて測長貯留装置を機能する。以上のようにRDPを電気的結合により連結することにより、従来この装置が持っている、よこ入れ最終速度を減速してから、よこ入れを完了する、拘束飛走の特性を持たすことができ、糸切れ、係止ピンあたり、打ち戻り、等の織物上の不具合を解決し、FDPが持つ、扱い安さ以上の操作性の向上も可能になる。
【0010】
よこ糸補修等で1ピックのよこ糸が必要な時は1ピック機能のスイッチを入れると、設定器から入力された織り幅からよこ糸長さを求め、測長貯留装置を駆動するモータのエンコーダのパルス数を数えて回転量を制御する。この機能はよこ糸が織物内部で切れて、再度1ピックよこ糸が必要なときに有効で、よこ入れ用の噴射装置との連携で機能する。
【0011】
省エネルギーに付いては、ブロァーによる連続ブローを廃止して、ドラムによこ糸を巻き付けるタイミングに高圧な空気をノズルから噴射してドラムへの巻付けを行い、巻き付きが一度開始したらよこ糸とドラムの接触抵抗で巻き付けが行われるので空気噴射を停止する。従来の連続ブローから、巻き付け時のみの空気噴射になり省エネルギーが達性される。又よこ入れ期間については、従来のブローを廃止し、本発明の空気噴射も行われないのでよこ入れ時のバックテンションと呼ばれる、よこ入れノズルの給糸側張力が低下し、よこ入れの省エネルギーが達成される。
【0012】
噴射ノズルのタイミング制御はエァージェットルームではよこ入れ用の補助ノズルの1個を利用して必要タイミングに空気の噴射を行う。よこ糸の係止はクランパーで行うが、拘束飛走でよこ入れ速度が減速しているので測長長さの精度には問題が無い。測長貯留駆動モータは一般的にACサーボモータが使用され、ジェットルームの起動時の立ち上がり時間約300mSecに十分追随する。又特開、平9−324344のように1ピックの回転が間欠駆動でなく連続駆動であり、発熱の問題は無い。
【0013】
【発明の実施の形態】
本発明を図1、図2、図3.により説明する、まず図1により説明すると、給糸1からよこ糸2が解除され測長ガイド3を通り測長プーリ4a,4bに挟まれて測長され、貯留ドラム用ガイド5を通り、貯留ドラム11に巻き取られる。測長プーリ4aは測長貯留駆動モータ9、測長側駆動プーリ10,測長プーリ駆動ベルト6を介して駆動される。測長量は織機のクランク軸に取り付けられた、図示していないエンコーダとの同期比率運転により運転され、織機1回転に対して、必要な1ピックの長さになるように制御されている。
【0014】
測長プーリ4bは測長プーリ4aに接触していて消極的に回転する。測長はよこ入れ停止期間にも連続して行われており、この期間よこ糸をプールしておく必要がある。よこ入れが完了するタイミングで空気噴射ノズル7が空気を噴射して、よこ糸測長プーリ4a、4bから送り出されるよこ糸を、貯留ドラム11に巻付くように、動機付けを行う。次のよこ入れを開始する時は、クランパー12が開き、よこ入れ用メインノズル14、図示していないサブノズル等が機能してよこ入れが開始される。貯留ドラム11に巻かれたよこ糸は、測長プーリ4a、4bから送り出される約3倍程度の速度で自由飛走が行われる。
【0015】
貯留ドラム11に貯留されたよこ糸が無くなると、よこ糸測長プーリ4a、4bから送り出される速度で、測長ドラム用ガイド4を介して、拘束飛走と呼ばれるよこ入れ速度でよこ入れが行われる。よこ入れが完了するとクランパー12が閉となり、よこ糸測長プーリ4a、4bから送り出されるよこ糸を貯留するため、空気噴射ノズル7から空気を噴射して、貯留ドラム11によこ糸を貯留する。以後この繰り返しが行われる。
【0016】
図2は電気回路のブロック図で電気的な仕組みについて説明する。設定器15により織物幅のデータを入力すると、計算機16によりドライバ17の駆動に必要なパルス数又は電圧をドライバ17の入力条件に合わせて計算する。織機から運転信号と織機側エンコーダEN1の信号が来ると設定器15からのデータを計算機16で計算し、ジェットルームと測長プーリ4a、4b、貯留ドラム11が一定の比率で同期運転されるように、ドライバ17へ駆動信号が出力される。
【0017】
ドライバ17は測長貯留駆動モータMを駆動し測長貯留駆動モータ用エンコーダ8のパルスをフィードバック信号として利用する。回転量は計算機16にも測長貯留駆動モータ用エンコーダ8からパルス数として送り込まれる。織機側エンコーダEN1のパルス信号と測長貯留駆動モータ用エンコーダ8のパルス信号が設定器15のデータにより必要な、一定の比率になるように計算機16は常に機能して、織物幅に一致したよこ糸長さが供給されるように機能する。
【0018】
よこ糸補修等で1ピック信号が来たとき、設定器15により入力された織物幅から、計算機16で予め測長貯留駆動モータ用エンコーダ8からのフィードバックパルス数を計算しておき、この数値になるまでドライバ17を通して、測長貯留駆動モータMを回転して1ピックの長さのよこ糸をよこ入れ側に供給する。
【0019】
図3について説明する、図3はよこ入れの飛走曲線を示し、本発明の自由飛走の後に拘束飛走が有る曲線とフリードラムプーリングの自由飛走のみの曲線を示している。この説明ではよこ入れ開始が60°、拘束飛走に入るタイミングが210°、よこ入れ完了が240°にして有るが、このタイミングは織機の条件により設定されるもので絶体的なものではない。ただ拘束飛走に入るタイミングを余り早くすると、自由飛走の速度を早くする必要がありエネルギーロスが大きくなる。
【0020】
説明は1色と呼ばれるよこ入れ装置が1個の物で説明してきたが2色で1x1と呼ばれる物にも適用可能で交互によこ入れする2色に付いて説明をしておくと、1色と同じ物を半分の速度で回転する同期比率の割合に設定して、測長貯留を行えば1x1のミキシングと呼ばれるよこ入れが可能である。この場合、給糸の解除速度を半分にして給糸での糸切れを防止できる。機能的には拘束飛走期間が約半分になるが、自由飛走のみに比較して、減速が緩やかに行われ織物欠点を防止する機能は1色と同じ効果がある。本発明はエァージェットルームに適した装置であるがウォータジェットルームにも使用可能である。
【0021】
【発明の効果】
本発明によれば、RDPが持つ自由飛走と拘束飛走の機能をそのまま持つており、FDPが持つ、よこ入れ完了時の急停止による糸切れ、このときの係止ピン部分に接触する糸の伸びによる織物欠点、打ち戻りと呼ばれる、よこ入れ完了時の急停止による反給糸側のよこ糸の織物側への戻りによる織物欠点が無くなる。織り幅を変更する時RDPは測長貯留経路のプーリ径変更を、FDPは貯留ドラム径の変更を必要としたが本発明では設定器15により同期比率の割合を変更するだけでよく、織り幅データを入力するだけでよこ入れ長さの計算を行い、変更が可能である。
【0022】
RDPは従来機械的な連結が多くて、ジェットルームに必要となっている、よこ糸自動補修等の自動化が困難であったが、この問題を解決した。さらによこ入れ停止期間に貯留する、貯留ドラム11へのよこ糸巻き付け動機に、空気噴射ノズル7を必要タイミングのみ空気噴射を行うので、貯留ドラム11への巻き付け動機用ブロァーが不要となり、又よこ入れ期間中にも貯留ドラム11近傍に空気の流れが無いのでよこ入れのエネルギーが少なくなり、省エネルギーとジェットルームの高速化が達成できる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in the performance of a weft length measuring storage device for a jet loom.
[0002]
[Prior art]
As a conventional technique, a rotary drum pooling method in which wefts are wound around a storage drum during a stoppage period. A free drum pooling system in which wefts are wound on a drum in advance and the required length is controlled by the drum diameter and the number of releases. As publicly known examples, there are a large number of published patent publications, Sho-60-71740, and the like. As a method for pulling out only the length necessary for filling, there is an open patent publication, Japanese Patent Laid-Open No. 9-324344. As a known example in which the length of one pick is continuously pulled out and stored in the weft insertion stop period and in the flow of air, there is an open patent publication No. 61-1667048.
[0003]
[Problems to be solved by the invention]
There are two types of jet looms: the water type and the air type. The water type has relatively little change in the fabric, and the mechanical functions of the length measuring and storage device are mechanically connected. A number of length measuring and storage devices called RDP are adopted as the method, and hereinafter, the rotary drum pooling system is referred to as RDP in the specification. The air type has many changes in the fabric and weft repair, the free drum pooling method, and the machine manufacturer's name called FDP, which changes the length of one pick by changing the drum diameter, which is necessary for steady operation and weft repair 1 Electrical length measuring and storage devices that perform picking and insertion by inserting and removing the locking pins are mainly used. In the following description, the free drum pooling method is referred to as FDP.
[0004]
FDP is relatively easy to handle, but the biggest drawback is that weaving several picks on the measuring drum and releasing the wefts as many times as necessary with the locking pin. There is no. RDP has free flight and restraint flight, and is an ideal weft insertion method that does not force the thread when wefting. However, it is mechanically connected to the machine body and is not suitable for changing the length of one pick required for changing the fabric width or for automatically repairing the weft yarn. The object of the present invention is to have a free-running and a restrained flying, and it is possible to easily change the length of one pick, and to measure and store a single pick-length weft necessary for repairing the weft. Device.
[0005]
Another drawback of RDP is that continuous blow is performed for drum winding motivation when the bound flight is completed and the weft yarn is wound around and stored in the storage drum. The weft insertion energy increases due to the resistance to the weft yarn by this blow. In addition, the blower motor capacity is typically 0.75 kW per set and has a large loss. This weeding energy and motor energy saving are also issues.
[0006]
A publicly known example of the published patent publication, Japanese Patent Laid-Open No. 9-324344, is not practical because the performance of the drive motor is difficult to follow the recent jet loom speed of 1000 RPM as an intermittent motion. Japanese Patent Publication No. 61-167048 disclosed that the wind flow for storing the weft yarn is opposite to the weft insertion, the back tension of the weft insertion is high, the weft insertion energy is high, and it has not been used recently.
[0007]
[Means and Actions to Solve Problems]
Utilizing the characteristics of free-running and restraint-running that RDP has, the ease-of-use function and energy saving that FDP has will be put out. Basically, the RDP is driven by an AC servo motor, and mechanical connection is changed to electrical connection by synchronous ratio operation by pulse calculation of the encoder attached to this motor and the encoder attached to the crankshaft of the jet loom. Achieve.
[0008]
Synchronous ratio operation is the rotation of the jet loom and the length measuring storage device rotating at a constant rate, and both are electrically connected. This ratio can be changed freely with the setting device, and the width of the fabric can be changed. When this happens, change this ratio and take action. When wefts for one pick are required, such as for weft repair, the synchronous ratio operation is not performed, and the number of pulses of the encoder of the motor that drives the length measuring storage device is counted to control the amount of rotation.
[0009]
When the weaving width required for the fabric is input from the setter, the mechanical gear ratio and the number of pulses per rotation of the encoder are calculated, and the ratio of the synchronization ratio is calculated by the computer. Is operated to function the length measuring storage device. By connecting the RDP by electrical coupling as described above, it is possible to have the characteristics of restrained flight that completes the weft insertion after decelerating the weft insertion final speed that this device has conventionally, It is possible to solve problems on the fabric such as thread breakage, hitting the locking pin, rebound, etc., and improve the operability of the FDP beyond the handling ease.
[0010]
When weaving one pick is necessary for weft repair, etc., when the 1 pick function is switched on, the weft length is obtained from the weaving width input from the setting device, and the number of pulses of the encoder of the motor that drives the length measuring storage device To control the amount of rotation. This function is effective when the weft yarn is cut inside the fabric and one pick weft yarn is needed again, and functions in cooperation with the weft insertion device.
[0011]
For energy saving, the continuous blow by the blower is abolished, and the drum is wound with high-pressure air at the timing of winding the weft thread on the drum. Once the winding starts, the contact resistance between the weft thread and the drum Since air is wound at, air injection is stopped. From the conventional continuous blow, air is injected only at the time of winding, and energy saving is achieved. Also, for the weft insertion period, the conventional blow is abolished, and the air injection of the present invention is not performed, so the yarn feeding side tension of the weft insertion nozzle, called back tension at the time of weft insertion, decreases, and energy saving of the weft insertion is reduced. Achieved.
[0012]
In the air jet loom, the timing of the injection nozzle is controlled by using one of the auxiliary nozzles for inserting the air at the required timing. The weft thread is locked by a clamper, but there is no problem in measuring length accuracy because the weft insertion speed is reduced by restrained flying. An AC servo motor is generally used as the length measurement storage drive motor, and sufficiently follows a rise time of about 300 mSec when the jet loom is activated. Further, as disclosed in JP-A-9-324344, the rotation of one pick is not intermittent driving but continuous driving, and there is no problem of heat generation.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
The present invention is illustrated in FIGS. First, referring to FIG. 1, the weft yarn 2 is released from the yarn feeding 1 and passed through the length measuring guide 3 and is measured between the length measuring pulleys 4a and 4b, passed through the storage drum guide 5, and then stored in the storage drum. 11 is wound up. The length measurement pulley 4 a is driven via a length measurement storage drive motor 9, a length measurement side drive pulley 10, and a length measurement pulley drive belt 6. The length measurement is operated by a synchronous ratio operation with an encoder (not shown) attached to the crankshaft of the loom, and is controlled to have a required one pick length for one rotation of the loom.
[0014]
The length measuring pulley 4b is in contact with the length measuring pulley 4a and rotates negatively. The length measurement is continuously performed during the weft insertion stop period, and it is necessary to pool the weft yarn during this period. The air injection nozzle 7 injects air at the timing when the weft insertion is completed, and motivation is performed so that the weft yarn fed from the weft yarn measuring pulleys 4 a and 4 b is wound around the storage drum 11. When the next weft insertion is started, the clamper 12 is opened, and the weft insertion main nozzle 14, a sub nozzle (not shown) and the like function to start the weft insertion. The weft yarn wound around the storage drum 11 is free-flying at a speed of about 3 times that is sent out from the length measuring pulleys 4a and 4b.
[0015]
When the weft yarn stored in the storage drum 11 disappears, weft insertion is performed at a weft insertion speed called “constrained flying” through the length measuring drum guide 4 at a speed fed from the weft yarn measuring pulleys 4a and 4b. When the weft insertion is completed, the clamper 12 is closed, and the weft yarn fed from the weft yarn measuring pulleys 4a and 4b is stored, so that air is injected from the air injection nozzle 7 and the storage drum 11 stores the weft yarn. This is repeated thereafter.
[0016]
FIG. 2 is a block diagram of an electric circuit and explains an electrical mechanism. When the fabric width data is input by the setting device 15, the number of pulses or voltage required for driving the driver 17 is calculated by the calculator 16 according to the input conditions of the driver 17. When an operation signal and a signal from the loom encoder EN1 come from the loom, the data from the setting device 15 is calculated by the calculator 16, so that the jet loom, the length measuring pulleys 4a and 4b, and the storage drum 11 are operated synchronously at a constant ratio. In addition, a drive signal is output to the driver 17.
[0017]
The driver 17 drives the length measurement storage drive motor M and uses the pulses of the length measurement storage drive motor encoder 8 as a feedback signal. The rotation amount is also sent to the computer 16 as the number of pulses from the length measurement storage drive motor encoder 8. The calculator 16 always functions so that the pulse signal of the loom-side encoder EN1 and the pulse signal of the length measuring storage drive motor encoder 8 are in a certain ratio required by the data of the setting device 15, and the weft yarn that matches the fabric width. Acts as length is supplied.
[0018]
When one pick signal comes for weft repair or the like, the number of feedback pulses from the length measuring storage drive motor encoder 8 is calculated in advance by the calculator 16 from the fabric width inputted by the setting device 15 and becomes this value. Then, the length measuring and storing drive motor M is rotated through the driver 17 to supply a weft thread having a length of 1 pick to the weft insertion side.
[0019]
Referring to FIG. 3, FIG. 3 shows a wetting flight curve, showing a curve with restraint flying after free running according to the present invention and a curve with only free running of free drum pooling. In this explanation, the weft insertion start is 60 °, the timing of entering the restraint flight is 210 °, and the weft insertion completion is 240 °, but this timing is set according to the conditions of the loom and is not absolute. . However, if the timing of entering restricted flight is too early, it is necessary to increase the speed of free flight, and the energy loss increases.
[0020]
The explanation is that the weft insertion device called one color has been explained with one thing, but it is also applicable to the thing called 1x1 with two colors, and if we explain about the two colors to be inserted alternately, one color If the same thing is set to the ratio of the synchronous ratio which rotates at a half speed, and length measurement storage is performed, weighing called 1 × 1 mixing is possible. In this case, the yarn releasing speed can be halved to prevent yarn breakage during yarn feeding. Functionally, the restraint flight period is approximately halved, but the function of slowing down slowly and preventing fabric defects is the same as that of one color compared to free flight alone. The present invention is an apparatus suitable for an air jet loom but can also be used for a water jet loom.
[0021]
【The invention's effect】
According to the present invention, the RDP has the functions of free-running and restraint-running as it is, and the FDP has a yarn breakage due to a sudden stop when the weft insertion is completed, and a yarn that contacts the locking pin portion at this time The fabric defect due to the elongation of the weft and the fabric defect due to the return of the weft yarn on the non-feed side to the fabric side due to the sudden stop upon completion of weft insertion are eliminated. When changing the weaving width, the RDP needs to change the pulley diameter of the length measuring storage path, and the FDP needs to change the diameter of the storing drum. In the present invention, however, it is only necessary to change the ratio of the synchronization ratio by the setting device 15. The input length can be calculated and changed simply by inputting data.
[0022]
RDP has been difficult to automate, such as weft automatic repair, which has been required for jet looms because of many mechanical connections, but this problem has been solved. Furthermore, since the air injection nozzle 7 is air-injected only at the necessary timing to the weft winding motives to the storage drum 11 stored during the weft insertion stop period, the blower for wrapping motives to the storage drum 11 becomes unnecessary, and the weft insertion period Since there is no air flow in the vicinity of the storage drum 11 inside, the energy for filling is reduced, and energy saving and high speed jet loom can be achieved.
