Abstract Translated from Japanese (57)【要約】 【目的】 ステッチ幅やステッチ方向が常時変化する刺 繍縫合においても縫い糸に最適のテンションを与え、風 合いのよい刺繍製品を作成できるようにする。 【構成】 糸調子手段は、その制御状態に応じた張力を 縫い糸に与える。張力検出手段は縫い糸に発生する実際 の張力を検出する。基準データ発生手段は所望の張力を 示す基準データを発生する。糸調子制御手段は刺繍縫合 時にこの基準データ発生手段からの基準データと張力検 出手段で検出された実際の張力との間の偏差を求め、こ の偏差に基づいて糸調子手段が縫い糸に与える張力を制 御する。基準データ発生手段が発生する基準データとし ては、主軸の回転速度、ステッチ幅、ステッチ方向、前 回ステッチ方向と今回ステッチ方向との成す角度(ステ ッチ角度)などの刺繍縫合状態に対応した張力を予め記 憶しておけば、糸調子手段はその基準データに等しい張 力が縫い糸に発生するように制御され、実際に基準デー タに等しい張力が縫い糸に発生するようになるので、ミ シンは風合いのよい刺繍製品を作成できるようになる。 (57) [Abstract] [Purpose] Even in embroidery stitching in which the stitch width and the stitch direction are constantly changing, optimum tension is given to the sewing thread so that an embroidered product with a good texture can be created. [Structure] The thread tension means gives a tension to the sewing thread according to its control state. The tension detecting means detects the actual tension generated in the sewing thread. The reference data generating means generates reference data indicating a desired tension. The thread tension control means finds a deviation between the reference data from the reference data generating means and the actual tension detected by the tension detecting means at the time of sewing the embroidery, and based on this deviation, the tension applied to the sewing thread by the thread tension means is calculated. Control. As the reference data generated by the reference data generating means, the tension corresponding to the embroidery stitching state such as the rotation speed of the main spindle, the stitch width, the stitch direction, the angle formed by the previous stitch direction and the current stitch direction (stitch angle) is stored in advance. Then, the thread tension means is controlled so that the tension equal to the reference data is generated in the sewing thread, and the tension equal to the reference data is actually generated in the sewing thread, so that the sewing machine produces the embroidery product having a good texture. You will be able to create.
