Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thread stand for a sewing machine in which a plurality of bobbins are set on surfaces having different heights.

[0002]

2. Description of the Related Art Conventionally, when a plurality of bobbins are used, as shown in FIG. 3, a thread stand plate 19 is provided on both sides of a sewing machine main body 1 above a sewing machine table 1 (only one side is shown). On each of the thread stand plates 19, a plurality of rods 22 for raising the thread winding 26 and a plurality of circular grooves 23 centering on the rod 22 into which the end of the bobbin of the thread winding 26 enter are provided. Then, the respective rods 22 are sufficiently spaced from each other so that the yarns 25 of the yarn windings 26 are not entangled with each other.

[0003]

However, in the thread stand device as described above, the thread stand plates 19 are provided above the sewing machine table on both sides of the sewing machine main body 2 via the columns, respectively, so that the thread stand plate 19 is often installed. There is a problem that the area is required and the sewing machine table cannot be effectively used. Further, in the case of performing multicolor embroidery with the embroidery sewing machine, it is necessary to stand up more spools. In such a case, it may be impossible to secure an installation area for an additional spool stand.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a sewing machine thread stand device capable of standing a larger number of spools with a smaller area.

[0005]

In order to achieve this object, a thread stand device for a sewing machine according to the present invention is a thread stand for a sewing machine that supports a bobbin and supports the bobbin respectively and is arranged at different heights from each other. A plurality of supporting surfaces, and at least thread supporting means for guiding the threads of the bobbin supported by other supporting surfaces except the uppermost supporting surface.

[0006]

In the thread stand device for a sewing machine of the present invention having the above-mentioned structure, a plurality of support surfaces for supporting the respective bobbins are arranged at different heights, and the thread guiding means excludes at least the uppermost support surface. The thread of the spool wound on the other support surface is guided upward.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

A lower thread stand plate 19 which constitutes one supporting surface is fixed above the sewing machine table 1 through a pair of struts 1A. On the lower thread stand plate 19, a spool 26 similar to the conventional one is provided. A circular groove 23 centered on the rod 22 into which the bobbin end of the bobbin of the bobbin 26 for standing and the bobbin 26 enters
Are provided at four locations, respectively. Further, above the lower thread stand plate 19, the upper thread stand plate 1 constituting another supporting surface is formed.
8 are fixed via the pair of stanchions 1A, and rods 22 and grooves 23 are provided at four positions on the upper surface thereof in the same manner as the lower thread stand plate 19, and the spool on the lower thread stand plate 19 is wound. A plurality of yarn guides 24 serving as yarn guide means for guiding the yarns 26 are provided.

At the time of sewing, the thread 25 of the thread winding 26 which is erected on the lower thread stand plate 19 is guided by the thread guide 24 of the upper thread stand plate 18 and is provided on the thread guide bar 20 located above. It is guided through the thread guide 21 to the upper thread tension adjusting screw 6 above the sewing portion.

As described above, in the sewing machine thread stand according to the present embodiment, since the thread stand plates are provided in two stages, it is possible to stand the same number of spools 26 as the conventional case with a smaller area than the conventional case. Further, since the thread guide 24 is provided on the upper thread stand plate 18, the thread 25 of the thread winding 26 of the lower thread stand plate 19 can be smoothly guided.

In this embodiment, the thread stand plates are provided in two steps, but they may be provided in three steps and four steps. For example, in the case of three steps, the lowest thread stand board in the middle thread stand board. A thread guide for passing the threads from the thread stand plate may be provided, and a thread guide for passing the threads from the middle and lowest thread stand plates may be provided on the uppermost thread stand plate. As a result, more spools can be erected and multicolored embroidery can be applied. Further, although four thread windings are erected on one thread stand plate, it is desirable to determine the number according to the size of the thread stand plate.

Further, in this embodiment, as the thread guiding means, the thread stand plate is provided with holes or notches.
As shown in, a thread guide arm 30 for guiding the thread may be attached to the end of the thread stand plate 18, and a tube 31 may be provided directly above the hole on the thread stand plate so as not to get entangled with other threads. May be. Further, the thread guide arm 30 in FIG. 2 is provided on the thread stand plate 18, but may be configured to be supported from other portions.

In addition, various modes can be applied without departing from the gist of the present invention.

[0014]

As is apparent from the above description,
Since the thread spooling device for a sewing machine of the present invention has a plurality of supporting surfaces that respectively support the spools and are arranged at different heights, many spools can be stood up in a small area. Further, since the thread guiding means for guiding the thread of the thread wound on the support surface other than at least the uppermost support surface is provided, the thread on the lower support surface can be smoothly guided. it can.
