Description

[Detailed description of the invention] This invention has an original drawing stand and an embroidery frame, which move together in front, back, left and right directions, and are connected so that the rotation of the original drawing stand is transmitted to the embroidery frame. Sewing machine embroidery in which a fixed tracing needle is installed to point the original image, and by moving the original drawing table so that the tracing needle traces the original image, the movement is transmitted to the embroidery frame, making it possible to obtain embroidery with different thread alignment angles. This mount relates to a mount that is movably placed on a bed that pivots the original drawing stand in the device, rotatably supports the embroidery frame, and is equipped with transmission means for transmitting the rotation of the original drawing stand to the embroidery frame. be.

The applicant previously proposed the above-mentioned embroidery device, in which the original stage, the support frame that holds the embroidery device, the belt transmission device that transmits the rotation of the original stage to the embroidery frame, etc. are placed on the bed of the sewing machine. Since it is mounted on a mounting plate and is exposed, there are disadvantages in that it is easy for hands and fingers to accidentally touch and get caught during operation, and parts and other small items can easily fall off. did not exist.

In order to deal with these problems, the present invention replaces the above-mentioned mounting plate with a mounting stand consisting of a floorboard and a cover attached to the floorboard, and a holding device that supports an original drawing stand and an embroidery frame within the mounting stand. The original drawing stand is equipped with a transmission device that transmits the rotation of the original drawing stand in an embroidery style so that it can be rotated from the outside.

The following will be explained with reference to the drawings. FIG. 1 shows an example of an embroidery device to which the present invention is applied. Rail 4 with runner 33 attached to
Further, each of the runners 33 is engaged with a rail 6 installed in parallel on the mounting base 5 so that the rail 6 can run across the rail 4, and the original drawing stage 7 is connected to the mounting base 5. The support frame 9 of the embroidery frame 8 is rotatably attached to the embroidery frame 8 through an endless belt 10 that is passed between the original stand 7 and the support frame 9, and is rotatably attached to the embroidery frame 8 by several rollers 11. By operating the base 7 against the fixed tracing needle 12 as if tracing the original image placed on the original stage, the movement is transmitted to the embroidery frame 8, and the embroidery frame can be moved forward, backward, left, and right. In addition, by rotating it, you can create embroidery with different thread alignment angles.

In addition to the above-mentioned movements, the movement of the X-component and Y-component of the mount is supported by the presser foot and other fixing rails that are removably attached to appropriate locations on the sewing machine, as proposed earlier by the applicant. , a rail type consisting of a movable rail that intersects and slidably engages the fixed rail, or a presser bar or other fixed member attached to an appropriate position of the sewing machine and a mounting base consisting of a pair of parallel links. It is also possible to use a pantograph type connected by a link mechanism.

In the above-described embroidery device, the present invention has a mounting base 5.
is attached to the original drawing stand 7 and a floor plate 15 on which a roller 11 arranged around the periphery of the circular hole 14 is rotatably pivoted, and the upper surface is preferably flush with the original drawing stand 7 which is pivoted to the floor plate A circular arc 17 that fits the original art stand is formed on one side, and a circular hole 18 that is coaxial with the circular hole 14 is provided in the center, and the upper surface is supported by mounting bases 20 on both sides of the circular hole 18. The rail 6 is provided with a cover 19.

In the case shown in the figure, the cover is flush with the original drawing stand and the diameter of the arc 17 on one side is larger than that of the original drawing stand. It may be formed into

In this case, if the part covering the original drawing stand is large enough to cover the original drawing, at least that part is made of a transparent material, and the original drawing is inserted between the original drawing stand and the cover. be fixed in any way.

Further, although the roller 11 is pivoted to the floor plate 15, the cover or both ends thereof may be pivoted to both the floor plate and the cover.

Furthermore, instead of being rotatably held by rollers as shown, the support frame may be held by other types of rolling bearings or by sliding bearings.

In the device described above, the transmission between the original stage and the support frame can be done by friction transmission or gear transmission instead of belt transmission, and the embroidery frame can also be directly rotatably held without using the support frame. However, in either case, the above-mentioned mount according to the present invention can be used in the same way.

Figure 3 shows a mounting board with a rectangular hole 21 formed on one side.
This allows it to function as a handle when carrying the entire device, and also allows a tool case 22 to be fitted here (see FIG. 4).

According to the present invention, since the original drawing stand and the mounting base for attaching the embroidery frame are configured as described above, the appearance is clean and the beauty of the entire device is improved.Furthermore, there is no possibility of foreign matter getting into the device. Furthermore, it is extremely safe as there is no chance of fingers touching or getting caught in the transmission part during operation.
