For example, when embroidering on a T-shirt, trainer, or the like, the embroidery frame is supported by a holding arm that extends in a letter shape from the frame driving body. In such a configuration, when the weight of the pizza water is large, the letter-shaped retaining arm is bent downward by the weight of the pizza water, and the front end side of the embroidery frame sags downward, which adversely affects sewing. Has appeared. As a technique for preventing this problem, an embroidery frame supporting apparatus which has been conventionally supported to support the front end portion of the embroidery frame has been known (see, for example, Japanese Patent Application Laid-Open No. 2000-303339).

The embroidery frame support apparatus of the said patent document 1 is provided with the support arm arrange | positioned at the both side parts of the cylinder bed incorporating a kiln, and the support plate fixed to the front-end | tip of a support arm and functioning as a support member.

Then, the sewing head 2 is driven while driving the embroidery frame 6 in the X and Y directions by driving the Y-direction drive body 4 and the X-direction drive body 5 based on the embroidery data according to the embroidery contents to be executed. Sewing is performed by the cooperation of the sewing needle of 9) and the kiln 9. This embroiders the pizzas. At this time, since the front end of the embroidery frame 6 is supported by the embroidery frame support device 7, the tip of the embroidery frame 6 can be effectively prevented from falling down, and the sewing is not adversely affected. . In addition, the movement of the embroidery frame 6 in the X and Y directions with respect to the embroidery frame support device 7 is permitted by the interposition of the Y slide rail 12 and the X slide rail 15.

Next, the case where the embroidery frame 6 and the embroidery frame support device 7 currently attached to the sewing machine are removed to use another type of embroidery frame will be described. Initially, the screw N3 fixing the bracket 16 to the Y slide rail 12 is removed (see FIG. 7), and the embroidery frame 6 (bracket 19) is moved to the X-direction driving body 5. ) As shown in Fig. 9, the removed embroidery frame 6 is detached from the embroidery sewing machine with the X slide rail 15 and the bracket 16 mounted. Next, the embroidery frame support device 7 is removed from the cylinder bed 3 by removing the three screws N1 holding the embroidery frame support device 7 to the cylinder bed 3 (see FIG. 4). . Then, the cover 10 may be attached to the upper surface of the cylinder bed 3, and other kinds of embroidery frames (for example, hattles, etc.) and their supports may be attached to the embroidery sewing machine. In addition, when attaching the embroidery frame 6 and the embroidery frame support apparatus 7, work is performed in the reverse order.

In the above embodiment, an example of using the embroidery frame support device 7 according to the present invention for the auxiliary support of the embroidery frame 6 is shown. Below, as an example of another use of the embroidery frame support apparatus 7 which concerns on this invention, the example used for the support of the disk frame which holds a disk is introduced.

11 is a perspective view showing an example of a disk mold 26 for holding a disk object. As is well known, the disk frame 26 is configured to hold the fabric landing to be embroidered by using the embroidery clip 27. The disk frame 26 is fixed to the X-direction drive body 5 at its rear end by screws, and is mounted to be capable of being driven in the left-right direction (X direction) with respect to the embroidery sewing machine. By attaching the X slide rail 15 and the bracket 16 to the lower surface of the front end of the disc 26, the front end of the disc 26 is embroidered in the same manner as the above-described structure of the embroidery frame 6. It can be supported by the support device 7. That is, the disk frame 26 is fixed to the X-direction drive body 5 at the rear end thereof so that the disk frame 26 is supported in a letter shape in the sewing machine and the front end side is not sag down by the embroidery frame support device 7. Supported. Therefore, in the embroidery sewing machine provided with the embroidery frame supporting device 7 according to the present invention, the disk frame 26 can be mounted by the same support form as the embroidery frame 6 supported in the letter shape, and both of them are exchanged. This is possible. When using the disc 26 in a conventionally known embroidery sewing machine, the position of the front table 1a (see FIG. 1), which can be generally changed up and down, is set to the upper position, and the disc frame is formed by the front table 1a. It was supposed to support the whole of (26). Therefore, when replacing the embroidery frame 6 and the disk frame 2, it was necessary to change the position of the front table 1a (refer FIG. 1). In this regard, the embroidery frame 6 is supported by using the embroidery frame support device 7 according to the present invention and supporting the front end of the disk 26 by the Y slide rail 12 and the X slide rail 15. In addition, even when the disc 26 is used, it is unnecessary to change the position of the front table. Therefore, the mutual use of the embroidery frame 6 and the disk frame 26 becomes simpler.

As described above, according to this embodiment, the embroidery frame support device 7 can be fixed to the cylinder bed 3 (the sewing body) by screwing using three screws N1, Since the screw fixation work of the screw N1 is comprised so that it may be performed directly in front of the sewing table 1, the attachment / detachment work of the embroidery frame support apparatus 7 can be performed very easily.

Moreover, the base member 11 is unitized by uniting the base member 11 which becomes the installation base part of the Y slide rail 12 (support member) and the embroidery frame support apparatus 7 in the embroidery frame support apparatus 7. ), The embroidery frame support device 7 can be attached or detached in a state where the Y slide rail 12 (support member) is attached. Therefore, when the embroidery frame support apparatus 7 is attached to the cylinder bed 3, the work for the precision of the Y slide rail 12 is unnecessary. For this reason, the removal operation of the embroidery frame support apparatus 7 can be performed efficiently.

Moreover, also about the operation | work which removes the embroidery frame 6 from the embroidery frame support apparatus 7, the worker removes the screw N3 located immediately in front of the bracket 16 from the Y slide rail 12. By removing this, the embroidery frame 6 can be removed together with the X slide rail 15 (see the state of FIG. 9), and can be removed very easily. In addition, since the Y slide rail 12 does not need to be removed from the cylinder bed 3 in the replacement of the embroidery frame 6, the replacement operation becomes very simple.

In addition, according to the embroidery frame support device 7 according to the above embodiment, the embroidery frame 6 is supported at the tip of the Y slide rail 12 having a variable length, whereby the embroidery frame of various sizes can be freely used. It becomes possible to cope. That is, by sufficiently taking the slide amount of the Y slide rail 12 to correspond to the embroidery frame of the maximum size used, the same embroidery frame support device 7 can freely cope with embroidery frames of various sizes. do.

In addition, in the above embodiment, the removal of the embroidery frame 6 has been described as removing the screw N3 fixing the Y slide rail 12 and the bracket 16 (see FIG. 7), but is not limited thereto. Instead, the screw N2 fixing the X slide rail 15 and the bracket 16 may be removed (see FIG. 8). When the screw N2 is removed, the screw is removed from the lower side. However, since the screw fixing point is just in front of the sewing machine, this can be easily performed.

Further, in the above embodiment, an example in which the X slide rail 15 made of two-stage channel members is provided as a member for supporting the embroidery frame 6 at the distal end of the embroidery frame support device 7 is described. Instead of the slide rails 15, a linear rail (sliding member engaged with the rail and the rail) may be used, and the rail may be provided on the lower surface of the front end of the embroidery frame 6, and the sliding member may be provided to the bracket 16. .
