【課題を解決するための手段】
前記目的を達成するために、請求項１に記載の本発明は、所定の布をＸ方向およびＹ方向に移動させ、この布に対して所望の縫い目を形成するためのＸ−Ｙ送り駆動装置において、Ｙ方向に平行な軸線をもつスプラインシャフトを駆動するＸ駆動手段と、前記スプラインシャフトとＹ方向に固定したＹレ−ルとに沿い移動可能なＹ移動部材と、前記Ｙ移動部材に支持されたＸレ−ルと、前記Ｘレ−ルに沿い移動可能なＸ移動部材と、基部が前記Ｘ移動部材に固定され、布押さえ枠を支持した押さえ台と、前記スプラインシャフトとＹ移動部材とに支持されたスプロケットに掛け渡され、上面にＸ移動部材が固定された環状のＸタイミングベルトと、Ｘ方向の軸線を持つＹ駆動軸を回転させるＹ駆動手段と、Ｙ駆動軸とミシンフレ−ムに設けられたスプロケットに掛け渡され、少なくとも、Ｙ移動部材が固定された環状のＹタイミングベルトと、前記Ｙレールの下面の両側がミシンフレームに固定され、Ｙレールの下面側にＸタイミングベルトの下面が通っている構成とした。 0019
[Means for solving problems]
In order to achieve the above object, the present invention according to claim 1 is an XY feed drive device for moving a predetermined cloth in the X and Y directions and forming a desired seam on the cloth. In, an X driving means for driving a spline shaft having an axis parallel to the Y direction, a Y moving member that can move along the spline shaft and a Y rail fixed in the Y direction, and a support for the Y moving member. The X rail, the X moving member that can move along the X rail, the holding base whose base is fixed to the X moving member and supports the cloth holding frame, and the spline shaft and the Y moving member. An annular X timing belt that is hung on a sprocket supported by the above and has an X moving member fixed on the upper surface, a Y drive means that rotates a Y drive shaft having an axis in the X direction, a Y drive shaft, and a sewing machine frame. An annular Y timing belt that is hung on a sprocket provided on the cloth and to which at least a Y moving member is fixed , and both sides of the lower surface of the Y rail are fixed to the sewing machine frame, and an X timing belt is attached to the lower surface side of the Y rail. The lower surface of the is passed through .

請求項２に記載の発明は、Ｙ移動部材が固定されたＹタイミングベルトの上面が、Ｘタイミングベルトの中を通るように設けた構成とした。請求項３に記載の発明は、前記Ｙ移動部材のＹレ−ルを、Ｙレ−ルの両端を支持するように設け、そのＹレ−ルの下方に補強部材設けた構成とした。 The invention according to claim 2 has a configuration in which the upper surface of the Y timing belt to which the Y moving member is fixed is provided so as to pass through the X timing belt . The invention according to claim 3 has a configuration in which the Y rail of the Y moving member is provided so as to support both ends of the Y rail, and a reinforcing member is provided below the Y rail.

[Action] According to the XY feed drive device of the sewing machine according to the present invention, an X moving member is fixed to the upper surface of the annular X timing belt, and the lower surface of the X timing belt is below the Y rail. Since it passes through, the height of the XY feed drive device is lowered, an accurate and beautiful pattern can be formed on the cloth, and the commercial value of the sewn product can be improved. Further, since the Y timing belt to which the Y moving member is fixed passes through the annular X timing belt, the height of the XY feed drive device is lowered, an accurate and beautiful pattern is formed on the cloth, and sewing is performed. The commercial value of the product can be improved.
