Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to embroidery sewing machines and other general sewing machines in which a plurality of threads are arranged on the upper part of the sewing machine body so that the threads can be smoothly threaded without tangling the threads. The present invention relates to a sewing thread storage device that allows thread to be easily changed as well as to be fed out.

[Conventional technology and its problems]

Even in general sewing machines, it is necessary to change the thread depending on the type of cloth to be sewn, the color of the cloth, etc. In this case, a preset is provided on the upper part of the sewing machine body, and the bobbin wound with the colored thread necessary for this preset is replaced each time.

Therefore, it is time-consuming to change the thread, and it is also necessary to store the bobbin when not in use.

In addition, in embroidery sewing machines that use a much larger number of threads than sewing machines, multiple presets are arranged on the top of the sewing machine body, and a bobbin of the desired color thread is inserted into the presets and raised.
When in use, the necessary thread is fed out from this prefectural bobbin.

However, since an industrial embroidery sewing machine has 10 to 20 sewing machine heads arranged in one main body, there is a limit to the number of bobbins that can be arranged above each head.

Therefore, more bobbins than the prefectural number provided in the head of the sewing machine cannot be erected at one time, and depending on the number of colored threads required, it is necessary to replace the bobbins. Also, multiple threads may become intertwined with each other.

In order to eliminate this drawback, the applicant of the present application proposed Utility Model Application No. 57-1
No. 87177, No. 58-14873, No. 58-353
The invention was disclosed in Publication No. 71.

These sewing machine thread storage devices support the bobbin horizontally, stack the bobbins vertically in multiple stages, and also arrange multiple threads horizontally according to the width of the sewing machine head to stand the bobbin up. - It is now possible to use a much larger number of bobbins - However, when using such a bobbin, the thread may become entangled at the bottom of the bobbin, giving unnecessary tension to the thread.
Sometimes thread breakage occurred.

The present invention further solves this problem, and makes it possible to smoothly unwind the yarn without entangling the yarn, and to easily change the yarn.

[Means for solving problems]

A spool support rod for supporting the spool and an adjustment rod for tilting the spool forward are provided on the inner bottom surface of an outer case or a spool case in which the spool can be stored, and a thread hook is attached to the front end of the bobbin. A large number of these outer cases are installed and used on the sewing machine frame.

In addition, instead of the adjustment rod protruding from the inner surface of the outer case or the bobbin case, an elastic material such as cotton, feathers, or animal hair is housed in the case, and the thread that is unwound from the bobbin spool is inserted and held at the bottom of the bobbin bobbin. Try to prevent this.

Furthermore, the cap of the thread winding case can be opened and closed in half.Next, the sewing thread storage device of the present invention will be described based on a first embodiment shown in FIGS. 1 to 4.

In the figure, reference numeral 1 denotes a box-shaped outer case with an open end, which stores and supports a bobbin spool B containing the required number of threads in a tilted horizontal or nearly horizontal state. A part or all of the bobbin can be stored inside by laying down the bobbin, and the outer case 1 can be stably placed on a sewing machine's thread support stand (not shown), and the outer case There is a station in the center of the inner surface of the case 1 that is smaller than the paper tube area of the spool.This allows the desired spool B to be inserted and supported even if the sizes are different. Engagement pieces 11 and engagement grooves 12 are formed on the outer circumferential side wall of the outer case 1 for joining together when two or more outer cases are integrated vertically or horizontally, or even vertically and horizontally.

Engagement grooves 13.14 are provided at the lower portions of the opposing side pieces of the outer case 1, and the apron 4 is slidably inserted into the engagement grooves 13.14. This apron 4 is made of transparent synthetic resin and has a dish shape, and has retaining posts 41 and 42 that fit into the engagement grooves 13 and 14 at both ends, and a thread hook that supports a thread hook at the tip. A tool support piece 43 is provided. This apron 4 can be slid in the direction of appearance and retraction inside the outer case, but the bobbin B stored in the outer case is l
or 2 or more, and when arranging 2 or 3 threads in parallel, an apron 4 is used to prevent the threads unwound from each thread from intertwining with each other.
A partitioning rib 44 is provided on the top surface. When there are two threads in parallel, one rib 44 is formed at the center of the apron as shown in the figure, and when there are three threads in parallel, two ribs 44 are formed. Furthermore, in an embodiment in which the bobbins are stored in two or three or more stages in the vertical direction within the outer case, one apron is stored in each bobbin thread in each row, and the apron is used to draw out the yarn for each bobbin thread in each row. It is supported so that it does not sag.

Since the thread spool support rod 3 protruding from the inner inner surface of the outer case is thinner than the inner diameter of the thread tube, even if the thread spool is inserted into the rod, it cannot firmly support the thread spool. For this purpose, a spool fixture 5 made of an elastic material is fitted to the outer periphery of the spool support rod. The spool fixing device 5 is formed in a ring shape from sponge or other material, and is slid along the spool support rod according to the diameter and size of the spool to fit and hold the spool at a predetermined position. It is something that provides good support.

Further, an adjustment rod 6' is vertically adjustable and protrudes from the inner surface of the outer case above the bobbin support rod 3, and can be fixed at any predetermined position. Therefore, when the bobbin B is fitted to the bobbin support rod via the bobbin support tool, the adjustment rod 6 is also inserted into the yarn tube and lengthened. The adjustment rod 6 is brought into contact with the upper part of the inner circumferential surface of the yarn tube, and is lifted to support the yarn tube so that the rear end of the yarn tube is higher than the front end, that is, the bobbin is tilted slightly forward from horizontal. Thereby, when the thread is let out, the thread is reliably let out without getting caught in the step part of the bobbin winder.

Further, as shown in detail in FIGS. 1 and 3, the thread hook 7 has a three-pronged tip, and has a required gap 72 on both sides of the central piece 71.
1 and 73, and the outer pieces 74 and 75 are arranged opposite each other, and the tip of one of the outer pieces 74 is bent in an inverted U shape so that it is the center piece, and the U-shaped bent part 74a at the tip of the outer piece 74 of the bracket is formed.
is made elastic so that the yarn fed out from the bobbin spool is inserted into the gap 72 between the bent portion 74a and the center piece, and a sponge is provided in the gap 73 between the other outer piece 75 and the center piece 71.・An elastic material 76 such as felt is inserted, and the thread that has passed through the gap 72 is made to surround the outside of the outer piece 75, returned to the bobbin winding side, and then inserted into the gap 73,
The thread is lightly pinched between the elastic members 76, thereby applying a desired tension to the thread and preventing the thread from twisting. When threading the thread through this thread hook, the end of the thread is pushed into the gap 72 from above as shown in the first ryi, and then inserted into the gap 73 so as to surround the center and outer pieces 75. This can be done easily and quickly without letting go of the thread.

The thread hook 7 has a support rod 77 protruding from its base, and this support rod 77 is fitted and held at the tip of the apron into a thread hook support piece 43 provided at a position in front of the bobbin winder. The thread hanging tool 7 is tilted in the left-right direction about a rod 77 to facilitate replacing and taking out the thread.

In place of the adjustment rod 6 shown in the figure, a highly elastic body made of rolled cotton, synthetic cotton, feathers, animal hair, etc. is housed in the outer case, which supports the lower bottom of the bobbin winder and allows it to be unwound from the bobbin winder. It is also possible to insert the thread between the bottom of the bobbin winder and the inner bottom surface of the outer case so as to prevent the thread from being unrolled smoothly.

Next, a second embodiment shown in FIGS. 5 to 8 will be described. In this second embodiment, the apron is formed integrally with the outer case, and weights are suspended to prevent the hem threads from getting tangled. The other configurations are almost the same as the first embodiment.

Therefore, detailed explanation of the configuration in the second embodiment will be omitted. The bobbin B is fitted onto the bobbin support rod 3, and the lower bottom plate 15 of the outer case L to be stored is made to protrude by a required length toward the front, and the apron 16 which is made transparent is integrated into the lower bottom plate 15.
Formed integrally with Therefore, this apron 16 is fixed to the lower bottom plate of the flat outer case.

The thread hook 7 is the same as that shown in FIG. 1, but a slide rod 77 protruding from the bottom is rotatably and slidably fitted into a boss portion 17 formed at the bottom of the apron 16 for support. Adjust the thread hanger to the required position in front of the bobbin so that the thread always receives the appropriate tension depending on the length of the bobbin, prevents tangling, and allows for smooth edges, and when replacing the bobbin. This thread hanging tool is rotated about the slide rod 77 to change its position from the front of the bobbin. A boss portion 18 is provided on the inner surface of the upper side piece of the outer case l.
A rod 8 such as a piano wire is inserted and supported in the boss portion 18 so as to be freely retractable, and a weight 82 is hooked on the hook portion 81 at the tip of the rod 8.
2 is brought into contact with the bobbin or a part of the thread wound on the bobbin,
This weight prevents the thread being unwound from the bobbin with more slack than necessary and allows the thread to be unwound sequentially every time around the outer circumference of the bobbin. Since this weight 82 is a retractable type, it can be removed when unnecessary, such as when replacing the bobbin, and is particularly effective when the bobbin has strong threads such as gold thread or silver thread. In this second embodiment as well, the first
As in the embodiment, an elastic body may be used instead of the adjustment rod.

Next, a third embodiment shown in FIGS. 9 to 11 will be described. The outer case 1 has a box shape with at least the front side open, and two to four or more pincushion cases can be inserted and supported inside the outer case 1. Case 1. 1 so that the 1. It has the same configuration as the second embodiment. In this third embodiment, the bobbin support rod and the adjustment rod are not provided directly on the outer case, but are provided on the bobbin case 9 that is inserted into the outer case 1.

A bobbin fixing device 5 made of an elastic body is fixed to the bobbin support rod 3 to support the bobbin, and its structure and operation are the same as in the first embodiment. An adjustment rod 6 is provided on the bottom surface of the main body so that it can be adjusted in the vertical direction, that is, in the straight direction (diameter line) connecting the center of the bottom surface 91a of the main body and the outer peripheral surface.
Insert the tip of this adjustment rod 6 into the end of the bobbin so that it touches the upper part of the inner peripheral surface of the bobbin, and lift it so that the rear end of the bobbin is higher than the tip, that is, the bobbin is leveled. Support it by leaning forward a little more. As a result, when the thread is let out, the thread is reliably let out without getting caught in the step part of the bobbin winder.The main body 91 has a bottomed circular vibe shape, and the outer case l
It can be supported simply by fitting inside.

The cap 92 fitted to the main body 91 is transparent so that the colored thread of the bobbin B stored inside can be easily identified from the outside.
A cylindrical portion 92a and a truncated conical portion 92b that fit into the main body 91 are continuously formed, and a cylindrical portion 92c that fits in the main body 91 is continuously formed.
A groove for feeding out the thread is formed on the top surface 92d of the cap 92 continuously with the groove 92c, and this top surface 92d
A thread hook 7 is provided protruding from the outer surface of the. This thread hanging tool 7 has a rectangular gutter shape with an open top and front surface, and an elastic material 76 such as felt or sponge is inserted into the inside of the thread hanging tool 7 to pinch the thread being let out and give the required tension. 1. This is the same as the second embodiment.

Therefore, in this third embodiment, only a plurality of outer cases 1 are fixed at predetermined positions of the sewing machine, and a desired colored thread is first stored in each of a plurality of thread winding cases 9. This storage is the same as in the first embodiment; the bobbin B is fitted onto the bobbin support rod 3, and the bobbin bobbin B is given a required inclination angle using the adjusting rod 6.

Then, a cap 92 is attached to the main body 91, and at this time, the end of the thread is guided out of the cap through the groove 92c and held by the thread hook 7, and stored in this thread winding case.
The spool case containing colored threads according to the embroidery pattern etc. is used by being fitted or exchanged into the outer case. In this embodiment, each colored thread is stored or replaced in each thread winding case, so it is easy to store a large number of colored threads, and it is also easy to replace threads in the outer case in a short time. It has the advantage of being protected. It is also possible to use an elastic body housed in the main body of the thread winding case instead of the adjustment rod.

FIGS. 12 and 13 show a fourth embodiment. This embodiment differs from the previous two embodiments in that a plurality of thread winding cases 100 are arranged and installed directly on the sewing machine frame without using an outer case. This is made up of a bobbin case body 101 and a cap 102. The spool case main body 101 has a short tube shape with a bottom, and has a spool lead-out hole 101H bored in a part of its outer peripheral wall, and a spool support rod 3 for fitting and supporting a spool protruding from the inner bottom surface.
