Abstract

PROBLEM TO BE SOLVED: To provide a flat-knitting machine in which the static electricity can be removed from the charged elastic yarn with a simple structure.SOLUTION: A flat-knitting machine 1 comprises a discharging electrode 30 attached to a post 1a to face between a yarn tensioning unit 8 and an air flowing unit 9. Since the yarn tension is added at the yarn tensioning unit 8, the static electricity is removed by corona discharging between an elastic yarn 5 and the discharging electrode 30, even though the elastic yarn 5 is charged when the elastic yarn 5 is returned into the air flowing unit 9. Since the elastic yarn 5 is discharged, the yarn is neither clung nor stuck on the circumference metal part including the post 1a. The useless resistance and the like can be avoided when the elastic yarn 5 is fed into the yarn tensioning unit 8.

Description

本発明は、ゴム糸などと呼ばれる弾性糸を編糸として、糸張力を制御しながら編針に供給する場合などで必要な、編糸の戻し機能を備える横編機に関する。   The present invention relates to a flat knitting machine having a function of returning a knitting yarn, which is necessary when an elastic yarn called a rubber yarn is used as a knitting yarn and supplied to a knitting needle while controlling the yarn tension.

従来から、横編機で編地を編成する際に弾性糸を使用して、供給長さおよび糸張力を制御すれば、風合の異なる編地を編成することができる。糸張力の制御のため、編針へ弾性糸を供給する経路の途中に、弾性糸の送りとともに戻しも行う糸張力付加装置が設けられる。糸張力付加装置に弾性糸を供給する経路側では、弾性糸を戻す際に、弾性糸が弛み、周囲に絡まないように、空気流で弾性糸を案内することも必要となる(たとえば、特許文献1参照)。   Conventionally, knitted fabrics having different textures can be knitted by using elastic yarns when knitting a knitted fabric with a flat knitting machine and controlling the supply length and yarn tension. In order to control the yarn tension, a yarn tension adding device is provided in the course of supplying the elastic yarn to the knitting needle. On the side of the path for supplying the elastic yarn to the yarn tensioning device, it is also necessary to guide the elastic yarn with an air flow so that the elastic yarn is slackened and does not get entangled when the elastic yarn is returned (for example, patent Reference 1).

特開2008−274474号公報JP 2008-274474 A

特許文献1の糸張力付加装置では、弾性糸を送りローラと押えローラとの間で挟み、戻す際には回転方向を送る際と逆転させる。弾性糸は、芯材を被覆材で覆うような構造で、素材や、周囲の乾燥状態などによっては、ローラ間で挟まれると静電気も付加されやすくなる。弾性糸に静電気が付加されて帯電すると、糸張力付加装置から戻される弾性糸が支柱など、周囲の金属部分に静電気で付着して、空気流形成装置で戻す方向に案内しようとしても、円滑に戻すことができないおそれがある。   In the yarn tension applying device of Patent Document 1, the elastic yarn is sandwiched between the feed roller and the presser roller, and when returning, the rotation direction is reversed from that when sending the rotation direction. The elastic yarn has a structure in which the core material is covered with a covering material, and depending on the material and the surrounding dry state, static electricity is likely to be applied when sandwiched between rollers. When static electricity is applied to the elastic yarn and charged, the elastic yarn returned from the yarn tension applying device adheres to the surrounding metal parts such as struts by static electricity, and even if it tries to guide it in the direction to return it with the air flow forming device, it smoothly There is a risk that it cannot be restored.

本発明の目的は、簡単な構成で、帯電した弾性糸から静電気を除去することが可能な、横編機を提供することである。   An object of the present invention is to provide a flat knitting machine capable of removing static electricity from a charged elastic yarn with a simple configuration.

In the present invention, the discharge electrode may be
The interval between the elastic yarns can be switched between an interval at which the corona discharge occurs and a retreat interval larger than the interval.
Only when the elastic yarn is returned by the yarn tension applying device, the interval between the discharge electrode and the elastic yarn is changed so as to generate a corona discharge, and the others are switched so as to become a retracting interval.

本発明によれば、放電用電極は、糸張力付加装置に弾性糸を供給する経路に臨み、帯電時の弾性糸との間でコロナ放電を生じる間隔をあけて設けられる。弾性糸は、糸張力付加装置から戻されるときに、帯電して周囲の金属部分などにまとわりつきやすい。糸張力付加装置への弾性糸の供給経路に放電用電極を設けるという簡単な構成で、弾性糸が帯電しても、帯電した静電気を弾性糸と放電用電極との間のコロナ放電で除去することができる。   According to the present invention, the discharge electrode faces the path for supplying the elastic yarn to the yarn tension applying device, and is provided with an interval for generating corona discharge with the elastic yarn during charging. When the elastic yarn is returned from the yarn tension applying device, it is easily charged and clings to the surrounding metal portion. Even if the elastic yarn is charged, the static electricity is removed by corona discharge between the elastic yarn and the discharge electrode even if the elastic yarn is charged. be able to.

また本発明によれば、放電用電極は針状で、先端は弾性糸の戻しの方向に傾斜しながら弾性糸を供給する経路に向うので、糸張力付加装置から弾性糸が戻される際に、弾性糸が放電用電極の先端に引っ掛かりにくくすることができる。   Further, according to the present invention, the discharge electrode is needle-shaped, and the tip is directed to the path for supplying the elastic yarn while being inclined in the elastic yarn return direction. Therefore, when the elastic yarn is returned from the yarn tension applying device, It is possible to make it difficult for the elastic yarn to be caught on the tip of the discharge electrode.

また本発明によれば、糸張力付加装置から戻される弾性糸は、空気流形成装置で形成される空気流で案内され、迅速に戻すことができる。放電用電極が糸張力付加装置と空気流形成装置との間に設けられるので、この間で帯電した弾性糸が金属部分などに付着するのを防ぐことができる。   According to the present invention, the elastic yarn returned from the yarn tension applying device is guided by the air flow formed by the air flow forming device and can be returned quickly. Since the discharge electrode is provided between the yarn tension applying device and the airflow forming device, it is possible to prevent the elastic yarn charged during this time from adhering to the metal portion or the like.

また本発明によれば、糸張力付加装置から弾性糸を戻す際のみ、放電用電極と弾性糸との間で除電を行い、他は放電用電極を退避させて、弾性糸を糸張力付加装置に供給する際には、放電用電極の先端などに引っ掛からないようにすることができる。   Further, according to the present invention, only when the elastic yarn is returned from the yarn tension applying device, the static electricity is removed between the discharge electrode and the elastic yarn, and the rest is withdrawn to discharge the elastic yarn to the yarn tension applying device. When being supplied to the battery, it can be prevented from being caught by the tip of the discharge electrode.

図1は、本発明の一実施例である横編機1を、簡略化して示すブロック図である。FIG. 1 is a simplified block diagram showing a flat knitting machine 1 according to an embodiment of the present invention. 図2は、図1の放電用電極30近傍を、簡略化して示す部分的な正面図である。FIG. 2 is a partial front view showing the vicinity of the discharge electrode 30 of FIG. 1 in a simplified manner.

以下、図1および図2で本発明の一実施例である横編機1の概略的な構成を説明する。図2の説明では、先に説明する図1に示す部分と対応する部分には同一の参照符を付し、重複する説明を省略する場合や、図2には記載されず図1にのみ記載される部分に言及する場合がある。   Hereinafter, a schematic configuration of a flat knitting machine 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. In the description of FIG. 2, the same reference numerals are given to the portions corresponding to the portions shown in FIG. 1 described earlier, and duplicated descriptions are omitted, or not shown in FIG. 2 but only in FIG. 1. May refer to the part to be done.

図1は、横編機1の全体的な構成を簡略化して示す。各構成部分の相対的な向きや大きさも、説明の便宜上、変更していることがある。横編機1は、針床2の長手方向に沿ってキャリッジ3が往復走行しながら、編地を編成する。針床2には多数の編針が並設され、キャリッジ3に搭載されるカム機構で駆動されて編成動作を行う。キャリッジ3の走行時には、ヤーンフィーダ4が連行され、編地を形成するための編糸を編針に供給する。横編機1には複数のヤーンフィーダ4が備えられ、キャリッジ3が連行するヤーンフィーダ4を切換えることによって、編糸を切換えることができる。弾性糸5も、1つのヤーンフィーダ4を介して供給される。編糸としては弾性糸5以外も使用されるけれども、図示は省略している。   FIG. 1 shows a simplified overall configuration of the flat knitting machine 1. The relative orientation and size of each component may be changed for convenience of explanation. The flat knitting machine 1 knits the knitted fabric while the carriage 3 reciprocates along the longitudinal direction of the needle bed 2. A large number of knitting needles are arranged in parallel on the needle bed 2 and are driven by a cam mechanism mounted on the carriage 3 to perform a knitting operation. When the carriage 3 travels, the yarn feeder 4 is entrained to supply knitting yarn for forming a knitted fabric to the knitting needle. The flat knitting machine 1 is provided with a plurality of yarn feeders 4, and the knitting yarns can be switched by switching the yarn feeders 4 that the carriage 3 entrains. The elastic yarn 5 is also supplied through one yarn feeder 4. Although the yarn other than the elastic yarn 5 is used as the knitting yarn, the illustration is omitted.

弾性糸5は、供給源となる糸コーン6から糸切れ検出スイッチ7を経由して針床2の編針に供給する。糸コーン6から、糸切れ検出スイッチ7のアーム7aの先端に設けられるプーリ7bまで、下方から上方に弾性糸5を供給する経路の途中には、糸張力付加装置8が設けられる。糸張力付加装置8は、弾性糸5を上方の糸切れ検出スイッチ7側に送り込んだり、糸張力を増大させたりするように、弾性糸5を送る方向と糸張力とを調整することができる。   The elastic yarn 5 is supplied from a yarn cone 6 serving as a supply source to a knitting needle of the needle bed 2 via a yarn breakage detection switch 7. A yarn tension applying device 8 is provided in the middle of the path for supplying the elastic yarn 5 from below to the pulley 7b provided at the tip of the arm 7a of the yarn breakage detection switch 7 from the yarn cone 6. The yarn tension applying device 8 can adjust the feeding direction and the yarn tension so that the elastic yarn 5 is fed to the upper yarn breakage detection switch 7 side or the yarn tension is increased.

糸張力付加装置8の下方で、糸コーン6との間の弾性糸5の供給経路には、空気流形成装置9が設けられる。空気流形成装置9内には、弾性糸5が上下に挿通する通路9aが設けられる。通路9aに挿通する弾性糸5には、空気流形成装置9の上部に設けるノズル9bから空気を噴出させて、上方から下方に向う空気流を形成することができる。糸張力付加装置8から高速で弾性糸5を戻しても、空気流形成装置9で弾性糸5を確実に下方に案内し、絡まりを防止することができると期待される。   An air flow forming device 9 is provided in the supply path of the elastic yarn 5 to the yarn cone 6 below the yarn tension applying device 8. A passage 9 a through which the elastic yarn 5 is inserted vertically is provided in the air flow forming device 9. In the elastic yarn 5 inserted through the passage 9a, air can be ejected from a nozzle 9b provided in the upper part of the air flow forming device 9 to form an air flow from the upper side to the lower side. Even if the elastic yarn 5 is returned from the yarn tension applying device 8 at high speed, it is expected that the air flow forming device 9 can reliably guide the elastic yarn 5 downward and prevent entanglement.

横編機1の全体的な制御のために、制御装置10が設けられる。制御装置10には、操作入力部11、表示部12、CPU13、メモリ14、編成駆動部15、給糸駆動部16およびノズル9bからの空気の吹出しを制御するノズル駆動部17が含まれる。操作入力部11には、操作者からの指示などが入力される。表示部12では、各部の動作状態の表示などが行われる。操作入力部11への操作入力の結果は、CPU13に入力される。CPU13には、糸切れ検出スイッチ7など、各部からの信号も入力される。CPU13は、メモリ14に予め格納してあるプログラムに従う弾性糸5の張力設定動作を自動的に行うように制御することもできる。メモリ14には、操作入力部11への操作入力に関する応答や、表示部12への表示に関する制御のプログラムも予め格納される。   For overall control of the flat knitting machine 1, a control device 10 is provided. The control device 10 includes an operation input unit 11, a display unit 12, a CPU 13, a memory 14, a knitting drive unit 15, a yarn feed drive unit 16, and a nozzle drive unit 17 that controls the blowing of air from the nozzle 9b. An instruction from the operator is input to the operation input unit 11. The display unit 12 displays the operation state of each unit. The result of the operation input to the operation input unit 11 is input to the CPU 13. Signals from various parts such as the thread breakage detection switch 7 are also input to the CPU 13. The CPU 13 can also perform control so as to automatically perform the tension setting operation of the elastic yarn 5 in accordance with a program stored in the memory 14 in advance. The memory 14 also stores in advance a response related to an operation input to the operation input unit 11 and a control program related to display on the display unit 12.

糸張力付加装置8の制御は、CPU13が給糸駆動部16を介して行う。メモリ14には、各編地製品を編成する途中の段階で、たとえばキャリッジ3の1行程毎に送り出すべき弾性糸5の長さや糸張力を、制御データとして設定しておく。ノズル駆動部17は、空気流形成装置9への圧縮空気の供給経路に設けられる開閉弁18を駆動する。制御装置10は、開閉弁18から空気管路19を介して供給される圧縮空気について、空気流形成装置9のノズル9bからの吹出しを制御する。   The CPU 13 controls the yarn tension applying device 8 via the yarn feeding drive unit 16. In the memory 14, for example, the length of the elastic yarn 5 and the yarn tension to be sent out for each stroke of the carriage 3 are set as control data in the middle of knitting each knitted fabric product. The nozzle driving unit 17 drives an on-off valve 18 provided in a compressed air supply path to the air flow forming device 9. The control device 10 controls the blow-out from the nozzle 9 b of the air flow forming device 9 for the compressed air supplied from the on-off valve 18 via the air pipe 19.

糸張力付加装置8内には、送りローラ20と押えローラ21とが設けられ、弾性糸5をローラ間で挟み、送りローラ20の正転または逆転で、糸切れ検出スイッチ7側への送り込みまたは空気流形成装置9側への戻しを切換えることができる。弾性糸5を、糸切れ検出スイッチ7側へ送り込む場合は、プーリ7bで折返されて、下方の編針に供給される。このような糸張力付加装置8から編針までの経路では、弾性糸5には糸張力が付加されて伸張している状態となるので、帯電しても、周囲に絡まるおそれは少ない。しかしながら、糸張力付加装置8から空気流形成装置9側で、弾性糸5は、糸張力がほとんど付加されないので、弛みやすくなり、帯電していると、支柱1aなどの周囲の金属部分に付着して絡まりやすくなる。空気流形成装置9を設けて、空気流で弾性糸5を下方に案内しようとしても、弾性糸5が弛み、周囲に絡まると、円滑に案内しにくくなり、弾性糸5の方向を逆転させて糸張力付加装置8に送り込む際に、抵抗を受けたり、周囲に引っ掛かるような支障が生じやすくなる。   A feed roller 20 and a presser roller 21 are provided in the yarn tension applying device 8, and the elastic yarn 5 is sandwiched between the rollers. When the feed roller 20 is rotated forward or backward, it is fed to the yarn breakage detection switch 7 side. The return to the air flow forming device 9 can be switched. When the elastic yarn 5 is fed to the yarn breakage detection switch 7 side, the elastic yarn 5 is folded back by the pulley 7b and supplied to the lower knitting needle. In such a path from the yarn tension applying device 8 to the knitting needle, the elastic yarn 5 is in a stretched state due to the yarn tension being added, so that even if charged, there is little possibility of being entangled with the surroundings. However, since the yarn tension is hardly applied on the side of the air flow forming device 9 from the yarn tension applying device 8, the elastic yarn 5 is easily loosened. When charged, the elastic yarn 5 adheres to surrounding metal parts such as the support pillar 1 a. It becomes easy to get tangled. Even if the air flow forming device 9 is provided and the elastic yarn 5 is guided downward by the air flow, if the elastic yarn 5 is loosened and entangled with the surroundings, it becomes difficult to guide smoothly and the direction of the elastic yarn 5 is reversed. When it is fed to the yarn tension applying device 8, it becomes easy to cause troubles such as receiving resistance or being caught around.

本実施例では、糸張力付加装置8と空気流形成装置9との間の経路に臨むように、放電用電極30が支柱1aに取付けて設けられる。糸張力付加装置8から空気流形成装置9に向けて弾性糸5が戻されるときに、弾性糸5が帯電しても、静電気は弾性糸5と放電用電極30との間で、非接触状態で生じるコロナ放電で除去される。弾性糸5は、放電用電極30で除電されているので、周囲の金属部分などにまとわりつきにくくなり、引っ掛かりにくくなる。弾性糸5を戻した後で、弾性糸5を再度糸張力付加装置8に送り込む際には、抵抗や支障なく、円滑に送り込みを行うことができる。   In the present embodiment, the discharge electrode 30 is attached to the support column 1a so as to face the path between the yarn tension applying device 8 and the airflow forming device 9. Even when the elastic yarn 5 is charged when the elastic yarn 5 is returned from the yarn tension applying device 8 toward the airflow forming device 9, static electricity is not in contact between the elastic yarn 5 and the discharge electrode 30. It is removed by corona discharge generated in Since the elastic yarn 5 is neutralized by the discharge electrode 30, it is difficult to cling to the surrounding metal portion and the like, and is difficult to get caught. When the elastic yarn 5 is returned to the yarn tension applying device 8 after the elastic yarn 5 is returned, the elastic yarn 5 can be smoothly supplied without any resistance or trouble.

図2に、近傍の構成として示すように、放電用電極30は、エアシリンダ31を介して、横編機1の支柱1aに取付けられる。ただし、取付けに関する構成は省略する。放電用電極30は、支柱1aなどに電気的に接続し、接地状態にしておく。さらに放電を容易にするように、電圧などを印加させることもできる。放電用電極30は、糸張力付加装置8と空気流形成装置9との間の位置に独立して設けるので、糸張力付加装置8や空気流形成装置9による電気的な影響を抑えて、コロナ放電による自己放電式除電を安定に行うことができる。放電用電極30は、針状であり、上下方向の弾性糸5の供給経路に対し、直交する横方向よりも、先端は戻す方向である下向きに傾斜している。たとえば、水平に対して数度から数十度の下向きの傾斜を設けて逃すことによって、糸張力付加装置8から下向きに弾性糸5が戻される際には、弾性糸5が放電用電極30の先端に引っ掛かりにくくすることができる。   As shown in FIG. 2 as a configuration in the vicinity, the discharge electrode 30 is attached to the strut 1 a of the flat knitting machine 1 via an air cylinder 31. However, the configuration related to mounting is omitted. The discharge electrode 30 is electrically connected to the column 1a and the like, and is in a grounded state. Further, a voltage or the like can be applied so as to facilitate discharge. Since the discharge electrode 30 is independently provided at a position between the yarn tension applying device 8 and the air flow forming device 9, the electrical influence by the yarn tension applying device 8 and the air flow forming device 9 is suppressed, and the corona Self-discharge type static elimination by discharge can be performed stably. The discharge electrode 30 has a needle shape, and the tip is inclined downward with respect to the supply path of the elastic yarn 5 in the vertical direction rather than the transverse direction orthogonal thereto. For example, when the elastic yarn 5 is returned downward from the yarn tension applying device 8 by providing a downward inclination of several degrees to several tens of degrees with respect to the horizontal direction, It can be made difficult to get caught at the tip.

図2(a)はエアシリンダ31で放電用電極30の先端を弾性糸5の供給経路に接近させている状態、図2(b)はエアシリンダ31で放電用電極30の先端を弾性糸5の供給経路から退避させている状態を、それぞれ示す。図1に示すように、エアシリンダ31は、開閉弁18から空気管路19に送込まれる圧縮空気が分岐して供給される。したがって、空気流形成装置9で下向きの空気流が形成される際に、エアシリンダ31も図2(a)の状態になるように切換えられる。この状態では、放電用電極30と弾性糸5の供給経路との間隔が非接触でコロナ放電を生じる間隔Daとなるように接近する。間隔Daは、たとえば数mmとなる。弾性糸5に静電気が溜って帯電していると、放電用電極30の先端付近と弾性糸5との間の空気がイオン化し、小さなパルス状の放電が連続的に、かつ比較的長時間にわたって発生する。帯電した弾性糸5が供給経路を外れて支柱1aに接近しようとすると、放電用電極30の先端にも接近し、コロナ放電も生じやすくなる。   2A shows a state in which the tip of the discharge electrode 30 is brought close to the supply path of the elastic yarn 5 with the air cylinder 31, and FIG. 2B shows the tip of the discharge electrode 30 with the elastic yarn 5 in the air cylinder 31. Each of the states retracted from the supply path is shown. As shown in FIG. 1, the air cylinder 31 is supplied with a branch of compressed air sent from the on-off valve 18 to the air pipe 19. Therefore, when a downward air flow is formed by the air flow forming device 9, the air cylinder 31 is also switched so as to be in the state of FIG. In this state, the distance between the discharge electrode 30 and the supply path of the elastic yarn 5 approaches the distance Da that generates a corona discharge without contact. The interval Da is, for example, several mm. When the elastic yarn 5 is charged with static electricity, the air between the vicinity of the tip of the discharge electrode 30 and the elastic yarn 5 is ionized, and a small pulsed discharge is continuously generated over a relatively long time. appear. When the charged elastic yarn 5 leaves the supply path and tries to approach the column 1a, it approaches the tip of the discharge electrode 30 and corona discharge is likely to occur.

このようなコロナ放電で除電を行う場合の他は、図2(b)に示すように、エアシリンダ31のストローク分、放電用電極30は、弾性糸5との間隔が、コロナ放電を生じる間隔Daよりも大きい退避間隔Dbに切換えられる。このような切換えによって、糸張力付加装置8から弾性糸5を戻す際を除く他の場合は、放電用電極30を退避させておくことができる。放電用電極30を退避させると、弾性糸5を糸張力付加装置8に送り込む際に、弾性糸5が振れて供給経路から外れても、放電用電極30の先端に引っ掛からずに、送り込みに無用な抵抗が生じないようにすることができる。   In addition to the case where static elimination is performed by such corona discharge, as shown in FIG. 2 (b), the distance between the discharge electrode 30 and the elastic yarn 5 is the interval at which corona discharge occurs, as much as the stroke of the air cylinder 31. It is switched to a retreat interval Db that is larger than Da. By such switching, the discharge electrode 30 can be retracted in other cases except when the elastic yarn 5 is returned from the yarn tension applying device 8. When the discharge electrode 30 is retracted, when the elastic yarn 5 is fed to the yarn tension applying device 8, even if the elastic yarn 5 swings out of the supply path, it does not get caught at the tip of the discharge electrode 30 and is unnecessary for feeding. Therefore, it is possible to prevent the occurrence of excessive resistance.

以上の説明では、放電用電極30を、下方の空気流形成装置9と上方の糸張力付加装置8との間で弾性糸5が下から上に向う縦方向の供給経路に臨むように設けているけれども、供給経路が横方向など、他の方向であっても、同様に除電を行うことができる。放電用電極30には、針状の電極ばかりではなく、非接触のコロナ放電式除電器として使用されているようなブラシ状の導電性繊維などを使用することもできる。放電用電極30は、弾性糸5に対して、エアシリンダ31で出没式にしているけれども、固定式にすることもできる。放電用電極30の出没にエアシリンダ31を設けているけれども、ソレノイドなどを用いて電気的に出没させるようにしてもよい。放電用電極30は、糸張力付加装置8と空気流形成装置9との間に独立して設けているけれども、糸張力付加装置8または空気流形成装置9のいずれかに付属させることもできる。   In the above description, the discharge electrode 30 is provided between the lower air flow forming device 9 and the upper yarn tension applying device 8 so that the elastic yarn 5 faces the vertical supply path from the bottom to the top. However, even if the supply path is in another direction such as a horizontal direction, the charge removal can be performed in the same manner. As the discharge electrode 30, not only a needle-like electrode but also a brush-like conductive fiber used as a non-contact corona discharge type static eliminator can be used. Although the discharge electrode 30 is projected and retracted with respect to the elastic yarn 5 by the air cylinder 31, it can also be fixed.
