Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bobbin thread bobbin holding tool for attaching a bobbin thread bobbin to an bobbin thread bobbin as a thread bobbin after the sewing of the sewing machine is finished.

[0002]

[Prior art]

 Although the upper thread and the lower thread are used for hooking the sewing machine, the amount of the lower thread used is extremely small compared to the amount of the upper thread used. On the other hand, bobbin bobbins were formed in the shape of a small car in which a brim was formed at both ends of a short tubular core, and these were arranged side by side in a case. However, since the upper thread and the lower thread are systematically used in different types such as color, thread, quality, thickness, etc., when the thread is used again, the bobbin to be used for the upper thread bobbin is searched for. I was having a really hard time.

In order to eliminate such irrationality in a sewing factory and improve work efficiency, the inventor of the present invention has proposed a bobbin thread bobbin holding tool and has actually used it in the field. (See Japanese Utility Model Laid-Open No. 4-17765).

The conventional bobbin thread bobbin holding tool proposed by the present inventor is used as a holding piece for holding the bobbin thread bobbin in the bobbin winding portion, and at the lower end edge or the upper end edge of the upper thread bobbin. A hooking portion for hanging is provided, and when used, the lower thread bobbin is housed in the upper thread bobbin with the hanging portion being hooked as such.

[0005]

[Problems to be solved by the device]

 According to the conventional bobbin thread bobbin holding tool as described above, it is possible to achieve the original purpose of attaching the bobbin thread bobbin to the needle thread bobbin when threading the thread. There were aspects that should be improved in terms of workability at the time of closing and picking up, and convenience such as color matching.

In terms of workability, when the bobbin thread bobbin is finished, it is necessary not only to attach a retainer tool to the bobbin bobbin but also to attach a retainer tool to the lower end or the upper end of the upper thread bobbin. However, it was very troublesome, and when the thread was used again, it was troublesome. In addition, when the upper thread bobbin is hung on the lower end portion, the upper thread bobbin is slanted and the upper thread bobbin inclines, which causes a problem that the upper thread bobbin lacks stability.

Regarding color matching, it is often conceivable to use a bobbin thread of several different colors as compared with the use of a bobbin thread, but according to the conventional holding tool, it can be stored in the bobbin thread bobbin. Since the number of bobbin bobbins is limited to one or two, there is an inconvenience in the compatibility of thread types.

In view of the above situation, the present invention improves the workability of storing and removing the lower thread bobbin, and the lower thread bobbin has a large number of pieces that can be stored in the upper thread bobbin. The purpose was to provide a holding tool.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention forms a frustoconical pedestal into which the lower end of an upper thread bobbin fits, and projects a support shaft through which the lower thread bobbin can be inserted from the center of its upper surface. A retainer for bobbin bobbins was constructed.

[0010]

[Work]

 Since the retainer for bobbin thread bobbins is configured as described above, even if there are many types of bobbin thread used for the upper thread, the bobbin bobbin for each type can be inserted and held in the spindle. By covering the upper thread bobbin with the pedestal so that the upper thread bobbin can be supported, a large number of lower thread bobbins can be accommodated together in the upper thread bobbin.

Since the pedestal has a truncated cone shape, the needle thread bobbin can be easily attached and detached regardless of its size or shape. Further, by providing a collar portion around the lower end of the pedestal with which the lower end of the tubular body portion of the upper thread bobbin selectively engages with the outer peripheral surface of the pedestal, a needle thread bobbin of a different type can be provided. Corresponding to, any of them can be supported.

In addition, if the lower surface of the pedestal is formed as a suction surface that is attachable to and detachable from the installation surface, it can be prevented from tipping over, so that the upper thread bobbin and the lower thread bobbin can be stably supported. can do.

[0013]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

The drawings show one embodiment, in which the bobbin thread bobbin holding tool H is a support for looping a bobbin thread bobbin b on a cradle 1 to which a bobbin thread bobbin B is fitted at the lower end. The shaft 3 is vertically arranged. Each of the needle thread bobbins B used has a cylindrical shape which has been conventionally generally used, but it can be supported regardless of its diameter. Further, not only when it is straight as shown in FIGS. 1 and 2, but also when it is frustoconical as shown in FIG. 3, it can be supported.

The pedestal 1 has a frustoconical shape in which the diameter gradually increases from the upper end to the lower end, and a flange 5 is provided at the lower end. Therefore, as shown in FIGS. 1 and 2, in the case where the upper thread bobbin B has a seat piece 7 that spreads like a trumpet at the lower end, the upper thread bobbin B hangs on the peripheral edge of the pedestal 1 at the lower end of the tubular body. The needle thread bobbin B is supported by the cradle 1. In addition, when the seat piece 7 is not provided, the lower end of the seat piece 7 may also hang on the peripheral edge of the pedestal 1 in the same manner, but if not, it can be received by the collar portion 5 as shown in FIG. Supported by.

The support shaft 3 is erected at the center of the pedestal 1 and has a small diameter through which the support hole 9 provided at the center of the bobbin bobbin b passes. Therefore, if the lower thread bobbin b is hung on the support shaft 3 so that it can be conveniently accommodated in the upper thread bobbin B, not only the case for storing the lower thread bobbin b becomes unnecessary, but also the lower thread bobbin b. You don't need a space to close the

The pedestal 1 further has a magnet 11 embedded in its lower surface. Therefore, if the shelf surface 13 on which the upper thread bobbins B are arranged is formed of a metal surface, the tail holding tool H can be stably stood up so as not to fall. Further, the upper thread bobbin B and the lower thread bobbin b can be easily taken out, and the shelf surface 13 can be inclined toward the front by, for example, about 45 degrees.

In the case described above, the attracting surface is provided by the magnet 11 on the pedestal 1, but it may be provided by other means such as adhesion of an adhesive tape.

[0019]

[Effect of device]

 As described above, according to the bobbin thread bobbin holding device of the present invention, the following excellent effects can be obtained.

When the bobbin thread bobbin is closed, it is a very simple procedure to insert the bobbin thread bobbin into the support shaft and fit the bobbin thread bobbin into the pedestal, and it is also easy to take out the bobbin thread bobbin. In addition, it is possible to improve the workability of handling the thread in the sewing factory, and it does not require a space for it, which is very convenient for managing the thread and is suitable for reducing the working cost.

Since a large number of bobbin bobbins can be inserted through the support shaft, a large number of different types of bobbin threads can be attached to the upper thread, and if the upper thread bobbin is removed, the types can be recognized at a glance. Since it is possible to know, the workability and management of the thread are improved in this respect as well, and the upper thread bobbin and the lower thread bobbin are stabilized in order to hold the lower thread bobbin at the center of the upper thread bobbin. Then you can leave it. Moreover, it has a simple structure and can be provided at low cost.

Further, if a flange portion is provided around the lower end of the pedestal so that the lower end of the tubular body portion of the needle thread bobbin selectively engages with the outer peripheral surface of the pedestal (claim 2). ), It is possible to stably support both types of needle thread bobbins having different diameters and shapes.

In addition, if the lower surface of the pedestal is formed as a suction surface that can be attached to and detached from the installation surface, the fall can be prevented, and the upper thread bobbin and the lower thread bobbin can be made more stable. It can be supported and conveniently sits on a sloped shelf.
