そして、 編機 7で生産されている編物に供給中の給糸部 1の給糸パッ ケージ (例えば A ) の糸に替えて別の給糸パッケージ (例えば B ) の糸 が必要となると、 制御部 5の指令に従って、 先ず、 走行中の給糸パッケ ージ Aの糸は糸貯溜部 4より上流側 (給糸部 1側) において走行を停止 する。 停止した給糸パッケージ Aの糸を糸選択部 2において糸選択部 2 の切断装置 4 7 (図 2 ) で強制切断する。 切断された給糸部 1側の袷糸 パッケージ Aの糸の糸端を該糸の糸端把持部が糸走行位置から外して待 機位置に戻し、 上記別の給糸パッケージ Bの糸端を保持している糸端把 持部 3 3 (図 2 ) が給糸パッケージ Bの糸端を糸走行位置に位置決めす る。 位置決めされた給糸パッケージ Bの糸端は、 後述する糸継部 3によ り、 供給されていた糸貯溜部 4側の給糸パッケージ Aの糸端に糸継ぎさ れ、 編機 7に給糸パッケージ Bの糸が供給されるようになる。 尚、 図 1 では、 給糸が 7本の場合について図示してあるが、 適宜変更自在である。 上記糸選択部 2に続いて配置される糸継部 3は、 上述のように、 例え ば、 給糸パッケージ Aから給糸パッケージ Bに、 編機 7へ供給する糸を 切り替える場合、 糸選択部 2において強制切断された給糸パッケージ A の糸貯溜部 4側の糸端と、 新たに供給する袷糸パッケージ Bの所望の種 類の糸端とを保持し、 所定長に切断し、 継なぎ合わせるものである。 糸 継部 3は、 後述する糸端切断装置、 糸継装置 6及び糸端を糸継装置の定 位置へ案内するガイ ド装置等を有するものである。 糸継装置 6としては、 空気式糸継装置が適用される。 When the yarn of another yarn supply package (for example, B) is required instead of the yarn of the yarn supply package (for example, A) of the yarn supply section 1 being supplied to the knitted fabric produced by the knitting machine 7, the control is performed. First, according to the command of the section 5, the running yarn of the yarn supply package A stops traveling upstream of the yarn storage section 4 (the yarn supply section 1 side). I do. The stopped yarn of the yarn supply package A is forcibly cut by the cutting device 47 (FIG. 2) of the yarn selection unit 2 in the yarn selection unit 2. The line end of the lined yarn package A on the side of the cut yarn supply unit 1 is removed from the yarn traveling position by the yarn end gripping portion of the yarn and returned to the standby position, and the yarn end of the another yarn supply package B is returned to the standby position. The held yarn end gripper 33 (FIG. 2) positions the yarn end of the yarn supply package B to the yarn traveling position. The positioned yarn end of the yarn supply package B is spliced to the yarn end of the yarn supply package A on the yarn storage unit 4 side supplied by the yarn splicing unit 3 described later, and supplied to the knitting machine 7. The yarn of the yarn package B is supplied. Although FIG. 1 shows the case where the yarn supply is seven, it can be changed as appropriate. As described above, for example, when switching the yarn to be supplied to the knitting machine 7 from the yarn supply package A to the yarn supply package B, the yarn splicing portion 3 disposed following the yarn selection portion 2 The yarn end on the yarn storage section 4 side of the yarn supply package A, which was forcibly cut in step 2, and the desired kind of yarn end of the newly supplied lined yarn package B are held, cut to a predetermined length, and spliced. It is to match. The yarn splicing section 3 includes a yarn end cutting device, a yarn splicing device 6 described later, and a guide device for guiding the yarn end to a fixed position of the yarn splicing device. As the yarn joining device 6, a pneumatic yarn joining device is applied.
図 2に、 糸継部の空気式糸継装置の適用例を示す。  Fig. 2 shows an application example of a pneumatic yarn joining device for the yarn joining part.
糸継部 3は基本的に糸継部材 3 7、 糸押え装置 3 8、 解撚ノズル 3 9、 4 0、 糸寄せレバー 4 8、 糸端切断装置 4 1、 4 2、 糸クランプ装置 4 The yarn splicing part 3 is basically a yarn splicing member 37, a yarn presser device 38, a untwisting nozzle 39, 40, a yarn pulling lever 48, a yarn end cutting device 41, 42, and a yarn clamp device 4.
3、 4 4及び糸貯溜部 4側の糸端を吸引保持する第 1のサクションパイ プ 4 5、 糸選択部 2側の糸端を吸引保持する第 2のサクションパイプ 4 6、 及び、 糸選択部 2側の糸端を糸継部材 3 7へガイ ドする旋回アーム 2 9により主に構成されている。 The first suction pipe 45 sucking and holding the yarn end on the side of the yarn storage section 4 and the second suction pipe 46 sucking and holding the yarn end on the yarn selection section 2 and the yarn selection It is mainly constituted by a swivel arm 29 for guiding the yarn end on the part 2 side to the yarn joining member 37.
糸継部材 3 7の中央には円筒状の糸継孔 4 9穿設され、 外部から糸を 揷入するのに適したスリッ 卜が糸走行方向に形成され、 更に、 該スリツ 卜近傍に糸継孔 4 9に向かって開孔し、 圧縮空気を噴出する噴出ノズル が穿設されている。 解撚ノズル 3 9、 4 0、 糸寄せレバー 4 8、 糸端切 断装置 4 1、 4 2、 糸クランプ装置 4 3、 4 4は、 図示しないカム機構 によって、 所定の順序で動作するようになっている。 旋回アーム 2 9は フレーム 5 0に回転自在に支持されている。 旋回アーム 2 9は略 L字型 で、 アームと一体の軸 5 3に設けた歯車 5 4と扇形ギア 5 5が嚙合し、 扇形ギア 5 5が制御部 5からの指令、 即ち、 糸継ぎ指令により駆動する プログラムカムにより駆動する。 5 6〜6 1は糸ガイ ドである。 In the center of the yarn splicing member 37, a cylindrical yarn splicing hole 49 is formed, and a slit suitable for inserting a yarn from outside is formed in the yarn running direction. A jet nozzle is formed in the vicinity of the shaft to open toward the yarn splicing hole 49 and jets out compressed air. The untwisting nozzles 39, 40, the yarn pulling lever 48, the yarn end cutting devices 41, 42, and the yarn clamping devices 43, 44 are operated in a predetermined order by a cam mechanism (not shown). Has become. The swing arm 29 is rotatably supported by the frame 50. The revolving arm 29 is substantially L-shaped, and a gear 54 provided on a shaft 53 integral with the arm and a sector gear 55 are combined with each other. The sector gear 55 is a command from the control unit 5, that is, a piecing command. It is driven by a program cam. 56 to 61 are thread guides.
次に、 糸継部 3の動作について述べる。  Next, the operation of the yarn joining section 3 will be described.
上述のように、 編機 7へ供給する糸を切り替える場合、 先ず、 制御部 As described above, when switching the yarn to be supplied to the knitting machine 7, first, the control unit
5の指令により糸貯溜部 4の糸受容動作が停止し、 走行中の糸が糸貯溜 部 4より上流側において走行を停止する。 停止した糸は、 図示しない糸 選択部 2の該糸の糸端把持部に保持され、 糸選択部 2の糸切断装置 4 7 により強制切断される。 糸選択部 2側の糸端は、 図示しない糸端把持部 に保持され、 走行位置から外し、 待機位置に送られる。 そして、 新たに 走行させる糸の糸端 Y Vが、 糸端 Y Vを保持していた糸端把持部 3 3に より糸走行位置に送られる。 一方、 糸選択部 2の糸切断装置 4 7に強制 切断された糸貯溜部 4の糸の糸端 Y Pは、 サクシヨンパイプ 4 5に吸引 保持される。 糸端 Y Pはサクションパイプ 4 5に吸引保持された状態で 糸クランプ装置 4 3によって糸端先端から定距離位置をクランプされ、 糸端切断装置 4 1により切断され、 フリー状態の糸端は解撚ノズル 3 9 に吸引されて糸端解撚が行われる。 The instruction of 5 stops the yarn receiving operation of the yarn storage unit 4, and the running yarn stops running upstream of the yarn storage unit 4. The stopped yarn is held by the yarn end gripping portion of the yarn of the yarn selection section 2 (not shown) and is forcibly cut by the yarn cutting device 47 of the yarn selection section 2. The yarn end on the yarn selection unit 2 side is held by a yarn end gripping unit (not shown), removed from the running position, and sent to the standby position. Then, the yarn end YV of the yarn to be newly traveled is sent to the yarn traveling position by the yarn end gripping part 33 holding the yarn end YV. On the other hand, the yarn end Y P of the yarn in the yarn storage unit 4 that has been forcibly cut by the yarn cutting device 47 of the yarn selection unit 2 is sucked and held by the suction pipe 45. The yarn end YP is clamped at a fixed distance from the end of the yarn end by the yarn clamp device 43 while being sucked and held by the suction pipe 45, and cut by the yarn end cutting device 41, and the free yarn end is untwisted. It is sucked by the nozzle 39 and the yarn end is untwisted.
糸端把持部 3 3により糸走行位置に送られた糸端 Y Vは、 糸端把持部 3 3から開放されると共に、 旋回アーム 2 9の先端のヤーングリツバ 3 0の可動片 3 2に糸端 Y Vを把持すると共に、 大きく旋回して、 カム板 The yarn end YV sent to the yarn traveling position by the yarn end gripping portion 3 3 is released from the yarn end gripping portion 3 3 and the yarn end YV is transferred to the movable piece 3 2 of the young crimp 30 at the tip of the turning arm 29. While turning the cam plate
5 2にヤーングリッパ 3 0の可動片 3 2の一部に設けられたローラが係 合して、 可動片が開き、 把持していた糸選択部 2側糸端を解放し、 サク ションパイプ 4 6内へ吸引される。 即ち、 アーム 2 9が旋回し、 糸選択 部 2側の糸端 Y Vが給糸パッケージから糸が引出されながら糸継部材 3 7上方に移動し、 略 1 8 0 °C旋回した位置で、 カム板 5 2に係合し、 破 線で示される糸 Y Uの如く、 サクションパイプ 4 6内へ吸引保持される のである。 The roller provided on a part of the movable piece 32 of the young ripper 30 is related to 52. At the same time, the movable piece is opened to release the gripped yarn end on the yarn selection section 2 side, and is sucked into the suction pipe 46. That is, the arm 29 rotates, and the yarn end YV of the yarn selecting section 2 moves upward while the yarn is being pulled out from the yarn supply package, and moves upward by approximately 180 ° C. It engages with the plate 52 and is sucked and held in the suction pipe 46 like the yarn YU indicated by the broken line.
糸端 Y Uはサクションパイプ 4 6により吸引保持された状態で糸クラ ンプ装置 4 4によりクランプされ、 糸端切断装置 4 2により切断され、 フリーな糸端は解撚ノズル 4 0に吸引され解撚作用が施される。 更に、 糸寄せレバー 4 8の旋回動により、 解撚ノズル 3 9、 4 0内の糸端が引 出され、 糸継部材 3 7の糸継孔 4 9内で重ね合わされて、 噴出ノズルか ら噴出された圧縮流体の作用により、 互いに糸端が糸継ぎされるのであ る。 このようにして、 各糸端 Y P、 Y Uは、 図 2の実線及び破線位置に 位置決めされて糸継準備が行われ、 上述した動作により糸継ぎが行われ るのである。 そして、 糸継ぎ完了を制御部 5が検知し、 糸貯溜部 4の糸 受容動作が再駆動すると共に、 停止していた糸聍溜部 4より上流側の糸 が再び走行し、 編機 7に供給する糸が切り替わる。  The yarn end YU is clamped by the yarn clamping device 44 while being sucked and held by the suction pipe 46, cut by the yarn end cutting device 42, and the free yarn end is sucked by the untwisting nozzle 40 and untwisted. The action is performed. Further, the yarn ends in the untwisting nozzles 39 and 40 are drawn out by the swiveling movement of the yarn pulling lever 48, and are superposed in the yarn splicing hole 49 of the yarn splicing member 37. The yarn ends are spliced together by the action of the jetted compressed fluid. In this way, the yarn ends Y P and Y U are positioned at the positions indicated by the solid and broken lines in FIG. 2 to prepare for the yarn splicing, and the yarn splicing is performed by the above-described operation. Then, the control unit 5 detects the completion of the piecing, the yarn receiving operation of the yarn storage unit 4 is re-driven, and the yarn upstream of the stopped yarn storage unit 4 travels again, and the knitting machine 7 The supplied yarn switches.
尚、 糸端 Y Pがサクションパイプ 4 5内に円滑に吸引されるようにす るためには、 サクションパイプ 4 5の開口は糸端を下から受けるように 上方へ向けておくのが好ましい。 糸選択部 2の糸切断装置 4 7とサクシ ョンパイプ 4 5との距離は、 短すぎるとサクションパイプ 4 5による糸 端吸引長さが短くなるので糸端の吸引捕捉の失敗する確率が高くなると 共に、 吸引捕捉後の吸引保持力が弱くなる。 つまり、 糸を緊張させる力 が弱くなり、 糸継ぎ動作が不良となることがある。 糸選択部 2の糸切断 装置 4 7とサクションパイプ 4 5との距離は、 長すぎると糸切断装置 4 7によって切られる部分の無駄が多くなり、 不都合となる。 故に、 吸引 保持力が過少とならない範囲で可及的に短いほうがよい。 In order to smoothly suction the yarn end YP into the suction pipe 45, the opening of the suction pipe 45 is preferably directed upward so as to receive the yarn end from below. If the distance between the yarn cutting device 47 of the yarn selection unit 2 and the suction pipe 45 is too short, the suction end length of the suction end of the suction pipe 45 will be shortened, so that the probability of failure of suction and capture of the yarn end will increase. However, the suction holding force after suction capture is weakened. In other words, the force for tensioning the yarn is weakened, and the piecing operation may be defective. If the distance between the yarn cutting device 47 of the yarn selecting section 2 and the suction pipe 45 is too long, the portion cut by the yarn cutting device 47 becomes wasteful, which is inconvenient. Therefore, suction It is better to be as short as possible as long as the holding force is not too small.
更に、 上記糸継部 3に続いて糸貯溜部 4が配置されている。 糸貯溜部 4は編機 7に連結されている。 糸継部 3側から糸貯溜部 4に供給される 糸 Yは、 糸貯溜部 4において所定量が貯溜され、 糸貯溜部 4から編機 7 へ供給されている。 そのため、 糸継部 3で糸継ぎが行われている間、 糸 継部 3側から糸貯溜部 4に糸 Yが供給されなくても、 編機 7を停止させ ずに連続運転することができる。 また、 糸貯溜部 4も制御部 5に連結さ れ、 制御部 5の指令により動作するために、 編機 7に供給する糸は所定 張力に対して張力変動をすることなく、 且つ、 編機 7の運転速度に対応 した糸 Yが糸貯溜部 4から編機 7へ供給される。  Further, a yarn storage unit 4 is arranged following the yarn joining unit 3. The yarn reservoir 4 is connected to a knitting machine 7. A predetermined amount of the yarn Y supplied to the yarn storage unit 4 from the yarn joining unit 3 side is stored in the yarn storage unit 4, and is supplied to the knitting machine 7 from the yarn storage unit 4. Therefore, even when the yarn Y is not supplied from the yarn splicing portion 3 to the yarn storage portion 4 while the yarn splicing portion 3 is performing the yarn splicing, the knitting machine 7 can be continuously operated without stopping. . In addition, the yarn storage unit 4 is also connected to the control unit 5 and operates according to a command from the control unit 5, so that the yarn supplied to the knitting machine 7 does not fluctuate in tension with respect to a predetermined tension. The yarn Y corresponding to the operation speed of 7 is supplied from the yarn storage 4 to the knitting machine 7.
図 3は、 糸貯溜部 4に配備される装置の適用例である回転式貯溜ドラ ムを示す側面図である。 回転式貯溜ドラム 1 5は、 フランジ部〗 5 a、 胴体 1 5 b、 溝 1 5 cを有る回転体であり、 フランジ部 1 5 aにプレツ シャローラ 1 5 dが圧接して回転しており、 糸 Yが胴体 1 5 bに巻回状 態で貯溜される。 ブローカバ一 1 5 e内の空気流で糸 Yが溝 1 5 cに係 止されている。 フランジ部 1 5 aにはモータ M 4が連結されており、 貯 溜ドラム 1 5を回転させる。 モータ M 4は制御部 5に連結され、 所定量 の糸貯溜部 Yが胴体 1 5 bに貯溜されるように制御されている。  FIG. 3 is a side view showing a rotary storage drum as an application example of the device provided in the yarn storage unit 4. The rotary storage drum 15 is a rotating body having a flange portion〗 5a, a body 15b, and a groove 15c, and a press roller 15d is pressed against the flange portion 15a to rotate. Thread Y is stored in a wound state on body 15b. The yarn Y is locked in the groove 15c by the air flow in the cover 15e. A motor M4 is connected to the flange portion 15a, and rotates the storage drum 15. The motor M4 is connected to the control unit 5, and is controlled so that a predetermined amount of the yarn storage unit Y is stored in the body 15b.
糸継部 3側から糸貯溜部 4に供給される糸は、 フランジ部 1 5 aにプ レツシャローラ 1 5 dで圧接し、 胴体 1 5 bに所定量が巻回状態で貯溜 され、 編機 7へ供給される。 そして、 糸継部 3で糸継ぎが行われて、 糸 継部 3から貯溜ドラム 1 5に糸 Yが供給されない時間は、 モータ M 4が 停止し、 卷回状態で胴体 1 5 bに貯溜された所定量の糸 Yが連続して編 機 7に供給される。 そのため、 編機 7を停止させずに、 連続運転をする ことができる。 また、 モータ M 4は制御部 5に連結され、 制御部 5に制 御されるため、 回転式貯溜ドラム 1 5の胴体 1 5 bから編機 7に供給さ れる糸 Yは、 所定張力に対して張力変動をすることがなく、 且つ、 編機 7の運転速度に対応して所定量の糸が糸貯溜部 4から編機 Ίへ供給され る ο The yarn supplied from the yarn splicing section 3 to the yarn storage section 4 is pressed against the flange section 15a with a pressure roller 15d, and is stored in a predetermined amount in a wound state on the body 15b. Supplied to During the time when the yarn is spliced at the yarn splicing section 3 and the yarn Y is not supplied from the yarn splicing section 3 to the storage drum 15, the motor M 4 is stopped and the yarn is stored in the body 15 b in a wound state. The predetermined amount of the yarn Y is continuously supplied to the knitting machine 7. Therefore, continuous operation can be performed without stopping the knitting machine 7. The motor M 4 is connected to the control unit 5 and is controlled by the control unit 5, so that the motor M 4 is supplied to the knitting machine 7 from the body 15 b of the rotary storage drum 15. The yarn Y to be supplied does not fluctuate with respect to the predetermined tension, and a predetermined amount of yarn is supplied from the yarn storage section 4 to the knitting machine 対 応 in accordance with the operation speed of the knitting machine 7.
そして、 編機 7の編工程で必要となる所望の糸 Υの所望量が、 給糸部 1の複数種類の給糸パッケージ A〜Gから編機 7に、 糸継部 3の糸継装 置 6にて糸継ぎをし、 糸貯溜部 4にて糸 Yを所定量貯溜して供給される ように、 前記各部の糸種の選択、 糸供給長さ等の動作を制御する制御装 置 5カ^ 設けられている。 制御装置 5は、 リレーシーケンス、 マイクロ コンピュータ等が用いられる。 即ち、 制御装置 5は、 例えば編機 7にて 生産している編物の編工程において糸の色を変える場合、 給糸部 1の給 糸している種類の糸が糸選択部 2によって変更する糸の選択、 又は、 糸 継部 3の糸継装置 6による変更する糸の糸継ぎ、 或いは、 糸貯溜部 4の 回転式貯溜ドラム 1 5や回転ガイ ド式貯溜ドラム等への糸の貯溜等の動 作およびタイミングを一括して制御する。  Then, the desired amount of the desired yarn な る required in the knitting process of the knitting machine 7 is transferred from the plurality of types of yarn supply packages A to G of the yarn supply section 1 to the knitting machine 7 and the yarn joining device of the yarn joining section 3 A control device for controlling operations such as selection of a yarn type of each of the above-mentioned portions and yarn supply length so that a yarn is spliced at 6 and a predetermined amount of yarn Y is stored and supplied at a yarn storage portion 4. There is provided. As the control device 5, a relay sequence, a microcomputer, or the like is used. That is, for example, when the color of the yarn is changed in the knitting process of the knitted fabric produced by the knitting machine 7, the control device 5 changes the type of yarn supplied by the yarn supply unit 1 by the yarn selection unit 2. Selection of yarn, or splicing of the yarn to be changed by the yarn splicing device 6 of the yarn splicing section 3, or storage of the yarn in the rotary storage drum 15 or the rotary guide storage drum of the yarn storage section 4, etc. The operation and timing of are controlled collectively.
以上のような各部による動作を、 システム全体の動作として説明する と、 編機 7で生産する編物に対して、 給糸部 1の揷着支持された給糸パ ッケージ A〜Gの中から、 例えば、 最初は、 給糸パッケージ Aの糸が糸 選択部 2において選択され、 糸継部 3、 糸貯溜部 4を介して編機 7に供 給される。 この時、 糸貯溜部 4には所定量の糸が貯溜され、 制御部 5に よって、 糸貯溜部 4から編機 7に供給される糸 Yは、 編機 7の運転速度 に対応し、 且つ、 所定張力に対して張力変動をすることがない。  The operation of each unit as described above is described as the operation of the entire system.For the knitted fabric produced by the knitting machine 7, the yarn supply packages A to G supported by the yarn supply unit 1 are selected from the following. For example, first, the yarn of the yarn supply package A is selected in the yarn selection unit 2 and supplied to the knitting machine 7 via the yarn joining unit 3 and the yarn storage unit 4. At this time, a predetermined amount of yarn is stored in the yarn storage unit 4, and the yarn Y supplied from the yarn storage unit 4 to the knitting machine 7 by the control unit 5 corresponds to the operation speed of the knitting machine 7, and The tension does not fluctuate with respect to the predetermined tension.
次に、 編機 7で生産する編物に、 例えば給糸パッケージ Bに切り替え る場合、 制御部 5の指令に従って、 先ず、 糸貯溜部 4の糸受容動作を停 止させ、 走行中の給糸パッケージ Aの糸は上流側において走行を停止し、 糸選択部 2の切断装置で強制切断する。 糸選択部 2において、 切断され た給糸部 1側の給糸パッケージ Aの糸は給糸パッケージ Bに入れ換える。 そして、 糸選択部 2において、 切断された糸貯溜部 4側の給糸パッケ一 ジ Aの糸と、 入れ換えられた給糸パッケージ Bの糸とを、 糸継部 3が保 持し、 所定量に切断後、 継なぎ合わせる。 糸継部 3で糸継ぎが行われて いる間、 糸貯溜部 4に糸 Yが供給されなくても、 糸聍溜部 4に貯溜され ている所定量の糸が、 制御部 5の指令に従って、 編機 7に供給されるた め、 編機 7を停止させずに連続運転をすることができる。 糸継ぎ完了を 制御部 5が検知すると、 糸貯溜部 4の糸受容動作が再駆動すると共に、 停止していた糸貯溜部 4より上流側の糸が再び走行し、 編機 7へ供給す る糸が給糸パッケージ Aから給糸パッケージ Bの糸に切り替わる。 上述 と同様に、 編機 7へ供給中は給糸部 1の給糸パッケージ A〜Gの中の所 望の糸に切り替えられ、 編機 7へ供給される。 Next, when switching to a knitted fabric to be produced by the knitting machine 7, for example, to the yarn supply package B, the yarn receiving operation of the yarn storage unit 4 is first stopped in accordance with a command from the control unit 5, and the yarn supply package being run The yarn A stops running on the upstream side and is forcibly cut by the cutting device of the yarn selection unit 2. In the yarn selecting unit 2, the cut yarn of the yarn supplying package A on the yarn supplying unit 1 side is replaced with the yarn supplying package B. Then, in the yarn selecting unit 2, the yarn joining unit 3 holds the cut yarn of the yarn supply package A on the yarn storage unit 4 side and the replaced yarn of the yarn supply package B, and a predetermined amount. After cutting into pieces, splice them together. While the yarn is being spliced in the yarn splicing section 3, even if the yarn Y is not supplied to the yarn storage section 4, a predetermined amount of the yarn stored in the yarn storage section 4 is supplied according to a command from the control section 5. Since it is supplied to the knitting machine 7, the knitting machine 7 can be operated continuously without stopping. When the control unit 5 detects the completion of the piecing, the yarn receiving operation of the yarn storage unit 4 is restarted, and the yarn upstream of the stopped yarn storage unit 4 travels again and is supplied to the knitting machine 7. The yarn switches from yarn supply package A to yarn in yarn supply package B. As described above, during supply to the knitting machine 7, the yarn is switched to the desired yarn in the yarn supply packages A to G of the yarn supply section 1 and supplied to the knitting machine 7.
また、 制御部 5は、 糸選択部 2、 糸継部 3、 糸貯溜部 4及び編機 7に 連結されるので、 糸選択部 2、 糸継部 3、 糸貯溜部 4及び編機 7のすベ ての動作を一括制御する。 それにより、 給糸パッケージ A〜Gの中の所 望の糸を所望のタイミングで編機 7へ供給することができ、 編機 7を停 止させることがなく、 安定した編機 7への供袷となる。 上記システムに よって継ぎ合わされた糸は、 空気式糸継ぎ装置によって糸継ぎされてい るので継ぎ目はほとんど単糸と区別することができない一本の糸状とな る。 なお、 色の配置、 長さ等は不規則或いは周期的に設定することも可 能である。 発明の効果  Further, since the control unit 5 is connected to the yarn selection unit 2, the yarn joining unit 3, the yarn storage unit 4 and the knitting machine 7, the control unit 5 is connected to the yarn selection unit 2, the yarn joining unit 3, the yarn storage unit 4 and the knitting machine 7. All operations are controlled collectively. As a result, the desired yarns in the yarn supply packages A to G can be supplied to the knitting machine 7 at a desired timing, and the knitting machine 7 can be stably supplied without stopping. It will be lined. Since the yarns spliced by the above system are spliced by the pneumatic splicing device, the seam becomes a single thread that can hardly be distinguished from a single yarn. Note that the arrangement and length of colors can be set irregularly or periodically. The invention's effect
上述のように、 本発明は、 空気式糸継装置を用いるため、 結び目が形 成されるノッターを適用した場合のように、 編工程で結び目が編針等に 引っ掛かり、 糸切断を生じると力、、 生産される編物に結び目が表面に突 出し、 商品価値が極めて低くなるという問題を防止することができる。 更に、 結び目の糸端を切るという工程が増え、 切りすぎると結び目が解 けるといった問題が発生することを防止することができる。 As described above, the present invention uses a pneumatic yarn splicing device. Therefore, when a knot is caught on a knitting needle or the like in a knitting process and a yarn is cut, as in the case of applying a knotter that forms a knot, a force, However, it is possible to prevent a knot from protruding from the surface of the knitted fabric to be produced, thereby reducing the value of the product extremely. Further, the number of steps of cutting the knot ends increases, and it is possible to prevent the problem that the knot is loosened if cut too much.
また、 本発明により、 糸継部で糸継ぎが行われている時間、 糸継部側 から糸貯溜部に糸が供給されなくても、 編機の運転速度に対応して所定 量の糸が糸貯溜部から編機へ供給され、 編機を停止させずに連続運転を することができる。  Further, according to the present invention, even when the yarn is not supplied from the yarn splicing portion to the yarn storage portion during the time when the yarn splicing portion is performing the yarn splicing, a predetermined amount of yarn can be produced in accordance with the operation speed of the knitting machine.
