2. Description of the Related Art In a conventional sewing machine with an embroidery function, an embroidery frame drive mechanism for moving an embroidery frame in the X and Y directions is provided substantially at the middle of a height direction of a sewing machine in which a cloth feed mechanism and the like are housed. Installed in the main body of the tubular bed.

[0003]

[0009] In a cylindrical bed body in which various mechanisms such as a cloth feed mechanism are mounted in advance and a embroidery frame driving unit is mounted in advance, the respective mechanisms are overlapped to form a cylindrical type. Extremely complicated structure inside the bed body,
Inconveniences have arisen, such as not only being difficult in manufacturing, and also expensive, but also extremely troublesome in maintenance and management.

[0004]

The inventor of the present invention has conducted intensive studies to solve the above-mentioned problems. As a result, the present inventors have developed a device for driving the embroidery frame in the X direction and a device for driving the embroidery frame in the X direction. An embroidery frame drive mechanism comprising a device for driving in the Y direction perpendicular to the embroidery frame driving mechanism is provided in an embroidery frame drive section machine frame base located immediately below the cylindrical bed of the sewing machine with an embroidery function, and the embroidery frame mounting portion is By using an embroidery frame driving device of a sewing machine with an embroidery function which is connected to the embroidery frame driving mechanism and is present outside the rear side wall of the embroidery frame driving unit machine base, the space in the cylindrical bed is extremely effectively used. It can be used, the structures can be simplified without each mechanism overlapping, and embroidery stitching and ordinary stitching can be suitably performed, and the object has been solved and the object has been achieved.

[0005]

In the present invention, the embroidery frame drive mechanism is provided in the embroidery frame drive section machine frame located immediately below the cylindrical bed of the sewing machine with the embroidery function, so that the cylinder provided substantially at the center in the height direction is provided. Unlike the conventional technique mounted in the main body on the mold bed, the entire space of the sewing machine can be effectively used without waste, and the mechanism of the sewing machine can be prevented from becoming complicated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the structure of an embodiment of the present invention, reference numeral 1 denotes a drive shaft (not shown) rotatably supported inside an arm frame of a sewing machine frame, and a vertical jaw 2 at a tip end. A needle bar mechanism having a directionally slidable needle bar (not shown) is supported.

Reference numeral 3 denotes a cylindrical bed of a sewing machine frame,
A needle thread thread catching device (not shown) and a cloth feeding device (not shown) having a feed dog are mounted therein, and the needle and the thread are attached to the tip of the needle bar by the rotation of the drive shaft. A lockstitch seam is formed in cooperation with the wheel catching device, and the movement of the feed dog causes the non-sewing cloth to move forward or backward in synchronization with the seam forming movement.

Reference numeral 4 denotes an embroidery frame drive unit frame base having a built-in embroidery frame drive mechanism. On the back side wall of the embroidery frame drive unit frame base 4, the longitudinal direction of the cylindrical bed 3 is oriented. A parallel and elongated opening 5 is formed. An embroidery frame mounting portion 6 is provided on a rod portion (not shown) that protrudes outward through the opening 5. The embroidery frame mounting portion 6 is configured to be connected to the embroidery frame driving mechanism and to be present outside the rear side wall of the embroidery frame driving portion machine frame base 4.

The embroidery frame driving mechanism comprises a device for driving the embroidery frame 18 in the X direction and a device for driving the embroidery frame 18 in the Y direction perpendicular to the X direction. It is built into the frame base 4.

The embroidery frame mounting portion 6 is composed of a lower base 7 and a mounting portion 9 which is pivotally mounted above the base 7 by a shaft portion 8. The upper surface of the mounting portion 9 has a magnet (see FIG. 1). (Not shown) and positioning pins 10 and 10 are provided.

Reference numeral 18 denotes an embroidery frame, and a positioning mounting portion 19 is fixed to one end. The positioning mounting portion 19 of the embroidery frame 18 is fitted to the positioning pins 10 provided on the upper surface of the mounting portion 9 and positioned, and fixed by a magnet.
When the cloth is set on the embroidery frame 18, the embroidery can be performed.

The embroidery frame 18 is controlled by the embroidery frame drive mechanism in the X direction and the Y direction to perform desired embroidery stitching. Next, when it is desired to remove the embroidery frame 18 and perform ordinary sewing, the embroidery frame mounting portion 6 to which the embroidery frame 18 is mounted is moved to the limit position in the X and Y directions of the embroidery frame drive range, that is, in FIG. The closest to the arm rising portion along the longitudinal direction of the cylindrical bed 3 (X
Direction) and move to the position closest to the cylindrical bed 3.

[0013]

According to the present invention, an embroidery frame driving mechanism comprising a device for driving the embroidery frame 18 in the X direction and a device for driving the embroidery frame 18 in the Y direction perpendicular to the X direction is provided with an embroidery function. The embroidery frame drive unit is provided in an embroidery frame drive unit machine base 4 located immediately below the cylindrical bed 3 of the sewing machine, and the embroidery frame mounting unit 6 is connected to the embroidery frame drive mechanism. The embroidery frame driving device of the sewing machine with the embroidery function which is provided outside the rear side wall of the sewing machine can first effectively use the entire space of the sewing machine without waste, and secondly reduce the complexity of the mechanism of the sewing machine. Thirdly, embroidery stitching and ordinary stitching can be suitably performed, and fourthly, various effects such as easy production and maintenance can be achieved.

These effects will be described in detail. The embroidery frame drive mechanism is concentrated in the embroidery frame drive unit frame base 4 located immediately below the cylindrical bed 3 of the sewing machine, so that the cylinder embroidery frame drive mechanism is provided. The embroidery frame drive mechanism and the like in the bed 3 can be separated from the embroidery frame drive mechanism, so that the space in the sewing machine can be used effectively. In particular, the embroidery frame drive mechanism, the cloth feed mechanism, and other mechanisms are used for the sewing machine. They are not packed in a small space inside, so that they can be formed into a structure that does not overlap complicatedly, and there is an effect that it is possible to avoid complication of the sewing machine mechanism.

Further, the embroidery frame drive mechanism is located immediately below the cylindrical bed 3 of the sewing machine, has a relatively large area, and has an embroidery frame drive mechanism capable of moving the embroidery frame 18 over a wide range. This has the advantage that the range of embroidery can be widened and various patterns can be sewn.

Further, since the embroidery frame drive mechanism is provided on the embroidery frame drive section machine frame base 4 immediately below the cylindrical bed 3 of the sewing machine, the embroidery frame provided substantially immediately above the embroidery frame drive mechanism having the embroidery frame drive section. Numeral 18 does not flutter or rattle on the cylindrical bed 3 and can be installed neatly, and thus embroidery sewing can be extremely suitably performed.

Further, the embroidery frame drive mechanism can be housed in the embroidery frame drive unit machine frame base 4 so that the embroidery frame drive mechanism and other mechanisms can be separated from each other. , Maintenance, etc. can be concentrated only on the lower part of the sewing machine, and the mechanisms other than the embroidery frame drive mechanism can be concentrated only on the three cylindrical beds in the middle part of the sewing machine. Etc. can be easily managed.
