Description

[Detailed description of the invention] [Industrial field of application] This invention is used for packaging spools.
A holder for fixing the end of a winding body, which can reliably and at low cost prevent the winding body from falling down, especially in the case of large cheese-shaped winding bodies that tend to fall off during transportation. The present invention relates to a body holder.

[Prior art]

As for the method of packing the winding body,
Publication No. 161988, Utility Model Application No. 53-161988, and Utility Model Application No. 161988-
It is known to collectively package spools using a spool holder such as that shown in Japanese Patent No. 186279. These known spool holders have a first
As shown in FIG. 1, a cylindrical holder main body 21 having an outer circumferential surface 21a that fits into the inner circumferential surface of the lower end of the bobbin 3 has a collar 22 protruding from the mouth edge of the lower end. As shown in FIG. 12, the spool holder 20 has a convex shape, and includes an inner circumferential surface 31a that fits into the outer circumferential surface of the lower end of the bobbin 3, and a bottom surface 31b that abuts against the lower end surface of the bobbin 3. Bottomed cylindrical holder body 3
As shown in FIG.
A bobbin 3 is placed on the bottom of the concave spool holder similar to the above.
The spool holder 30' can be roughly divided into a concave-convex shaped spool holder 30' having a protrusion 33 that fits into the inner peripheral surface of the lower end of the spool.

[Problems to be solved]

However, as winding bodies have recently become larger, the conventionally known winding body holders as described above are susceptible to yarn displacement, deformation, and even drop-off of the winding bodies due to vibration during transportation. This has led to the problem that it is easy to cause defects, which can result in serious defects during secondary processing.

That is, the known convex spool holder 20 is
As shown in FIG. 11, the holder body 21 is tightly fitted into the hole drilled in the partition plate 5, and the flange 22 is brought into contact with the lower surface of the fixed plate 5. Therefore, when the inner peripheral surface of the bobbin 3 is fitted into the holder main body 21, the lower end surface of the bobbin 3 comes into contact with the upper surface of the fixing plate 5. Therefore, the lower surface 4a of the thread 4 of the thread 2 held by the convex thread holder 20 and the upper surface 5a of the fixed plate 5
Since a large gap α is created between the thread body 2 and the thread body 2, it is not possible to prevent the thread body 2 from falling down.

In addition, a known concave and concave-convex shaped spool holder 3
0 and 30', as shown in FIGS. 12 and 13, fit the outer peripheral surface of the holder main body 31 into the hole drilled in the fixing plate 5, and bring the flange 32 into contact with the upper surface of the partition plate 5. Therefore, when the outer circumferential surface of the bobbin 3 is fitted to these holder bodies 31, the lower end surface of the bobbin 3 will be aligned with the bottom surface 3 of the holder body 31.
1b. Therefore, in the case of the concave or uneven spool holders 30, 30', if the depth of the holder body 31 is made sufficiently deep, the upper surface 5a of the fixed plate 5 and the spool 2 can be connected to each other. Although it is possible to prevent a gap α from occurring between the winding thread 4 and the lower surface 4a, the winding body holder 3 having a known concave and uneven shape can be used.
0 and 30', since the depth of the holder main body 31 is shallow, similarly to the case of the convex-shaped thread body holder 20,
The upper surface 5a of the fixed plate 5 and the lower surface 4 of the thread 4 of the thread body 2
A large gap α was created between the winding body 2 and the winding body 2, and it was not possible to prevent the winding body 2 from falling down.

That is, the known thread body holders 20, 30, 3
0' is the gap α shown in the 11th to 13th
Either insert a spacer (not shown) thick enough to fill the gap α, or increase the depth of the holder main body 31 in the case of concave and uneven spool holders 30, 30'. It was necessary to increase the depth and the thickness of the fixing plate 5.

In this way, in the conventionally known spool holder, in order to prevent the step from falling, a large number of cardboard or foamed plastics are used to fill the space between the upper surface of the fixed plate and the lower end surface of the cheese, or the fixed plate 5 is The problem was that the packaging needed to be thicker, which resulted in extremely high packaging costs.

Furthermore, if only to prevent rows from falling, a method has also been proposed in which a foamed plastic molded product is applied to both end faces of each spool, and each spool is individually wrapped with shrink film. Although this method has a good effect of preventing paragraph drop, it has problems such as extremely high material and work costs.

Therefore, in this invention, the concave and concave-convex shaped spool holders have been devised and improved, and a spool holder that can reliably prevent drop-offs at low cost has been completed.

[Means to solve the problem]

The spool holder of the present invention, which solves the above problems, has a concave or uneven shape, which has an inner circumferential surface that fits into the outer circumferential surface of the lower end of the bobbin, and a bottom surface that abuts against the lower end surface of the bobbin. This is an improved version of the spool holder of 2005, and a flange is provided on the outer peripheral surface of the bottomed cylindrical holder body at a position slightly lower than the mouth edge of the holder body. There is.

[Effect]

Since the spool holder of this invention has the above-mentioned configuration, when using it to collectively package spools, the thickness of the holder body above the flange must be lower than the height of the holder body. Use a thick fixing plate such as cardboard, make a hole in the fixing plate, fit the part of the outer circumferential surface above the flange of the holder body into the hole, and fix the upper surface of the flange. If it is used in contact with the bottom surface of the board, the bottom end surface of the bobbin fitted to the holder body will touch the bottom surface of the packaging box when it is used for the lowest tier of spools to be collectively packaged. The spool is in contact with the bottom surface of the holder body, which is supported by the holder, and the lower surface of the spool is close to the top surface of the fixed plate, which is supported on the holder body by the top surface of the collar. If this is used for the second or higher tier of spools that are collectively packaged,
The lower end surface of the bobbin fitted to the holder main body is in contact with the bottom surface of the holder main body, which is supported by the back surface of another thread holder fitted to the upper end of the bobbin of the lower tier side thread winding body, Since the winding body is fixed in the packaging box with the lower surface of the winding thread being close to the upper surface of the fixing plate, which is supported on the holder body by the upper surface of the flange, in either case, Also, the thread body does not fall off.

〔Example〕

One embodiment will be described with reference to FIGS. 1 to 7. This embodiment relates to a case where the present invention is implemented as a concave spool holder 1. The spool holder 1 of this embodiment has a spool 2. The outer peripheral surface 3 of the lower end of the bobbin 3
The outer peripheral surface 11c of the holder main body 11 is a low-height, bottomed cylindrical shape, and includes an inner peripheral surface 11a that fits into the inner peripheral surface 11a, and a bottom surface 11b that abuts against the lower end surface 3b of the bobbin 3.
, slightly w from the mouth edge 11d of the holder main body 11.
It is arranged in a downward position and has a flange 12 protruding from it.

Since the spool holder 1 of this embodiment has the above-described configuration, when the spool holder 1 of this embodiment is used to collectively package the spools 2, the winding of this invention is carried out as shown in FIG. A portion of the thread holder 1 above the flange 12 is fitted into a hole 6 of a fixing plate 5 made of, for example, cardboard, and the upper surface 12a of the flange 12 is brought into contact with the lower surface 5b of the fixing plate 5. Keep it like this,
When the lower end of the bobbin 3 is fitted onto the spool holder 1 fitted into the hole 6 of each fixed plate 5, the lower end of the bobbin 3 is supported by the spool holder 1. The lower surface 4a of the thread 4 of the thread body 2 has a collar portion 12.
Packaging box 7
It will be fixed inside.

In the embodiment shown in FIG. 3, the spool holder 1 according to the present invention is connected back to back to the upper end of the bobbin 3 of each spool 2. An example is shown in which the upper end portion of the bobbin 3 of each thread body 2 is fixed by fitting the thread body holder 1 in an inverted manner. As shown in the figure, a conventionally known concave, convex, or concave-convex shaped spool holder 3
0, 20, and 30' may be fitted to fix the upper end portion.

Furthermore, in each of the above embodiments, the holder main body 1
The lower end surface 3b of the bobbin 3 is supported by the bottom surface 11b of the thread body 2, and a slight drop within the range that can prevent a step from falling between the lower surface 4a of the thread 4 of the thread body 2 and the upper surface 5a of the fixing plate 5. Although an example is shown in which a gap is left, the thread holder 1 according to this invention has a gap between the flange 12 and
Since the lower surface 5b of the fixed plate 5 is in contact with the upper surface 12a, that is, the fixed plate 5 is supported on the spool holder 1 by the collar 12, so that the holder main body 11 is If the depth is set relatively deep to the length of the portion of the bobbin 3 exposed from the thread 4, the thread 4 of the thread body 2 will be deep as shown in FIG. The upper surface 5a of the plate 5 fixing the lower surface 4a
The load of the thread body 2 can also be supported within the packaging box by a thread end surface support method.

Next, another embodiment will be explained with reference to Figs. This embodiment differs from the embodiment in that the holder body 11 constituting it has a protrusion 13 on its bottom surface 11b that fits into the inner peripheral surface 3c of the bobbin 3.

Therefore, according to the uneven spool holder 1 of this embodiment, the lower end of the bobbin 3 is
It is also fixed to the spool holder 1 by the protrusion 13 that fits on the lower end, but apart from this point, how to use the concave-convex shaped spool holder 1 of this embodiment and its function. The effect is no different from that of the concave spool holder 1 described above. FIG. 10 shows an example of its use corresponding to FIG.

[Effect of idea]

The spool holder of this invention belongs to the category of concave or uneven spool holders in that the spool is fixed by bringing the lower end surface of the bobbin into contact with the bottom surface of the holder body. However, in contrast to the conventionally known concave or convex-concave shaped spool holders, which could be used by bringing the flange into contact with the upper surface of the fixing plate, the spool holder of the present invention The body holder is
The flange of the spool holder is brought into contact with the lower surface of the fixed plate, and the fixed plate is supported by the flange from below, so the lower end surface of the bobbin is supported by the bottom of the holder body. The upper surface of the fixing plate supported by the collar as described above can be directly positioned in close proximity to the lower surface of the wound yarn.

Therefore, according to the spool holder of this invention, the spool can be easily moved without inserting a spacer between the spool and the fixing plate, or without making the fixing plate particularly thick. Drop-off can be directly prevented by the partition plate itself located close to the lower surface of the winding yarn. That is, it is possible to reliably prevent paragraph breaks at low cost.

Moreover, as explained in the embodiment (FIG. 7), the spool holder of this invention can, if necessary,
It can also be used for packaging using the thread end support method.
In that case as well, the same effects as described above can be achieved.
