Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a packing structure and method for packing a ring-shaped article (for example, a magnetic tape wound body called a pancake).

During the manufacturing process, magnetic tapes loaded into tape cassettes, tape cassettes, etc. are wound around a hub at a predetermined tension and stored and transported as pancakes of a constant diameter.

FIGS. 7 and 8 show a pancake transport tray 28 that has been used conventionally.

This tray 28 consists of a tray body 22 made of foamed polystyrene in the shape of a regular octagon, a pancake storage area 23 of this tray body, and rings made of foamed polyethylene attached (adhered) to both sides of the tray body. shaped cushion materials 25 and 26, respectively. Further, a circular projection 27 is provided at the center of the tray body 22, and a pancake (magnetic tape 3 is connected to a hub 4) around this projection as shown in FIG.
2) is housed on the cushion material 25.

When transporting or storing, a plurality of trays 28 are stacked vertically as shown in FIG.
Only two trays are shown in the drawing. ) is pancake 2
is held between the cushion materials 26-25 of the upper and lower trays.

However, such a pancake packaging structure requires a large number of trays because each pancake is stored in its own transportation tray, and transportation costs are high. In particular, the manufacturing cost and maintenance cost of the tray body are high. is expensive. In addition, operations for storing and removing pancakes during transportation and storage are complicated and time-consuming.

C1 Purpose of the Invention The purpose of the present invention is to provide a ring that has a simple structure, can reduce costs, is easy to handle during transportation and storage, has excellent transportability, and can be packaged reliably. The purpose of the present invention is to provide a packaging structure for articles of this type.

29. The structure of the invention, that is, the present invention provides a core member that passes through a center hole of a ring-shaped article array formed by arranging a plurality of ring-shaped articles in a predetermined direction with their main surfaces adjacent to each other; a pressing member that presses both ends of the ring-shaped article array in opposite directions to each other along the predetermined direction; and a fixing means that relatively fixes the position of the core member and the pressing member; , fal This relates to a ring-shaped article packaging structure consisting of a coupling member that couples the pressing members at both ends, and a packaging film that is attached to the outer surface in this coupled state.

Further, the present invention provides a method for creating the above-mentioned packaging structure, including:
A core member is inserted into the center hole of a ring-shaped article array formed by arranging a plurality of ring-shaped articles in a predetermined direction with their main surfaces adjacent to each other, and then pressing members are attached to each end of this core member. The present invention also provides a method for packing a ring-shaped article, in which these pressing members are then bonded together to prevent them from coming off the core member, and then a packaging film is applied to the outer surface to package the entire ring-shaped article.

E, Example The present invention will be explained in detail below.

1 to 5 show a first embodiment. According to this example, each of the plurality of pancakes 2 is placed on the end surface 4 of the hub 4.
The pancakes a are arranged in the vertical direction as shown in FIG. 2 in a state where they are in contact with each other, forming a pancake array 10. At this time, the outer peripheral surfaces 3b of the magnetic tapes 3 are aligned in the vertical direction in the figure, and the side surfaces 3a of the magnetic tapes 3 are opposed to each other with a gap 8 between adjacent pancakes 2. .

A columnar or cylindrical core member 6 is passed through the center hole 5 of the pancake 2 or the pancake array 10 to fix the pancake 2 in position in the radial direction. Between each pancake or at both ends of the array, ring-shaped cushioning material 1 is provided.
6 is placed. Ends 6a and 6b of the core member 6 protrude from the through hole 5 of the pancake array 10. End portion 6a
, 6b are respectively fitted into holes 7a provided in a disc-shaped pressing member (plate) 7, and the core member 6 and pressing member 7 are fixed to each other. In this state, the pressing member 7 holds the pancake array 10 and presses both end surfaces 10a and 10b inward, respectively.

In this state, between the holding members 7 and 7 at both ends, the band hooks provided at four locations on each outer periphery are connected to the concave portion 1.
1, the plastic bands 12 are passed, for example, at right angles to each other so as to be firmly connected or tied together. In this case, the band 12 is sufficiently bitten into the concave portion by the fang, and the film 9 is also sufficiently bitten therein (see FIG. 4).

Furthermore, the whole is covered and wrapped with a film 9 called a shrink film, making the packaging more complete. That is, as shown in FIGS. 3 and 4, when the outside of the packaging structure is wrapped with the shrink film 9, the shrink film 9 is in the state shown by the dashed line.

Thereafter, when the shrink film 9 is subjected to heat treatment, the shrink film shrinks as shown by the solid line in the same figure, and further presses the pressing member 7 from the outside. This makes the packaging more complete and also has the effect of protecting the inside from water, etc. The positioning of the magnetic tape 3 is good, and the magnetic tape can be protected from impacts and damage thereof. Furthermore, since the pancakes 2 are not in direct contact (the magnetic tapes are in contact with each other), the tapes are not damaged by mutual contact.

According to the above-mentioned pancake packaging structure, the structure is simple and each part such as the holding member is easy to manufacture, so costs can be reduced.
It is easy to handle during storage, so transportation and storage costs are low, and its simple structure makes it lightweight.
Furthermore, the transportability is also good.

Moreover, by using the band 12 described above, the pressing members 7 to 7 can be bound together, and the packaging with the shrink film 9 can be made even more solid. Therefore,
This will stabilize the packaging.

In addition, since a ring-shaped groove 13 is provided on the upper or lower surface of the holding member 7, it is easy to hold it by hand during transportation (as shown in FIG. 5), which will be described later, and is convenient to carry.

Note that the pressing member 7 can be molded from styrofoam or the like. Further, the core member 6 can be manufactured from vinyl chloride resin, paper, etc., and the shrink film 9 can be manufactured from various resins such as polypropylene and polyethylene. Also, band 1
2 may be made of various resins such as polypropylene.

Next, a method for manufacturing the above-mentioned packaging structure will be explained.

Further, as shown in FIG. 5A, the same holding members 7 as described in FIG. 1 are fitted together. Here, the whole thing is shown horizontally, but this is a combination of the actual packaging process (
The same applies below).

Next, as shown in FIG. 5B, a binding band 12 is applied to each recess 11 of the holding member 7, thereby firmly fixing the holding member 7 and the core member 6 to each other. As a result, the pressing member 7 no longer comes off from the core member 6, and can be sent to the next shrinking process. That is, in reality, the floor surface 14 (or table) is in a state as shown in FIG. 5B.
Since the work is done while rolling the top, if band 12
If the holding member 7 is not tied with a band, the holding member 7 may come off from the core member 6, but since it is tied with a band 12, this does not happen, and the whole is rolled and sent to the next shrink (wrapping) machine. be able to. Therefore, it can be stably supplied to the shrink process.

FIG. 5C shows the state in which the entire package is covered with a shrink film 9 in the shrink process, resulting in the final packaging structure. At this time, when grasping the package with fingers 15 or hands as shown by the dotted chain line, if you put your fingers into the grooves 13 and lift it from both sides, the fingers 15 will be caught in the grooves 13, making it convenient to carry. be. This also applies to the state of the fifth day chart.

Note that due to the presence of the recessed portion 11, the device can be placed relatively stably if the recessed portion is placed so that it is exactly on the surface of the floor 14. However, as shown in FIG. 6, if the shape of the holding member 7 is changed, for example, into a large square, the
It can be placed quite stably on top.

Although the present invention has been illustrated above, the above-mentioned example can be further modified based on the technical idea of the present invention.

For example, the above-mentioned band 12 may be hung by only one other than the above-mentioned method. In addition to bands, strings, chains, or other connecting members may also be used. Moreover, packaging films other than shrink films can be used.

Further, the relative positioning of the pressing member 7 and the core member 6 may be achieved by fitting them together, by adhering them, or the like.

The dimensions, shapes, etc. of the holding member and the core member may vary. The core member 6 does not have to be cylindrical, and may be columnar. Further, the cross section does not have to be circular, and may have a triangular, quadrilateral, foot-shaped cross section, etc., but the important point is that it is inscribed in the inner peripheral surface of the center hole 5 and can be stably positioned, so that the pancake 2 does not wobble. A shape like this is preferable. The shape, dimensions, etc. of the center hole of the pancake array may also vary. The present invention is also applicable to packaging ring-shaped articles other than pancakes.

Effects of the Invention As described above, the present invention includes a core member passing through the center hole of the ring-shaped article array; and pressing both ends of the ring-shaped article array in opposite directions along the predetermined direction. and a fixing means for relatively fixing the positions of the core member and the presser member, so that a large number of ring-shaped articles can be packaged as one, and the structure is simple and manufacturing is easier. It is lightweight and suitable for transportation, and the packaging and unpacking operations during transportation and storage are simple and easy to handle, and the packaging itself is more than adequate. It also has excellent transportability.

Furthermore, since the pressing members are connected by the connecting member, the packaging can be made even more solid. Therefore, the packaging becomes more stable.

Furthermore, by using the above-mentioned coupling member, the pressing member no longer separates from the core member, and can be stably sent to the next packaging process.
