Abstract

PURPOSE:To obtain a sufficient protective faculty of a magnetic tape reel with a low cost and volume, by providing a center core in the center of the magnetic tape reel and also providing a side plate covering the outside of the magnetic tape reel between the over and bottom. CONSTITUTION:A doughnut type cushion sheet 5 is laid on a bottom 8 and a reel 3, on which a magnetic tape 1 is wound on the hub 2, is placed on the sheet and several reels 3 are stacked above the sheet 5. And a center core tube 9 is inserted into a center of the stacked reel, that is into an inner tube inserted by a reel shaft of the hub 2 and a cover 10 is placed. At this time, the both sides of this center core 9 come into contact with the bottom 8 and cover 10 respectively. Next, the side plate 11 made of paper or plastic cardboard is wound to cover the outer periphery of the reel 3 between the bottom 8 and the cover 10 and fixed by an adhesive tape 12 or the like and further, finally it is bound by a tight-band. In this way, material cost is greatly reduced without deterioration of protective faculty and the whole volume becomes small.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a packaging device for a magnetic tape roll in which a magnetic tape is wound around a hub in the form of a roll.

2. Description of the Related Art Conventionally, a packaging device for a magnetic tape roll has a structure as shown in FIG. , simply referred to as a rolled body) 3, and then placed the sheet 5 on top of the rolled body 3, stacked the sheets in this state in several layers, placed lids 6 made of Styrofoam on top and bottom, and finally placed the sheet 5 on top of the rolled body 3. As shown in Figure 6, it was tied and packed with a tight band 7 made of plastic such as polypropylene.

Problems to be Solved by the Invention However, in such a conventional groove formation, the same number of cases 4 as the wound bodies 3 are required, which has a high packaging material cost, resulting in high costs. Furthermore, Case 4 is made of polystyrene foam and has a large volume, resulting in a large volume of the final package, which has the problem of affecting the loading efficiency of truck transportation, container transportation, etc., and the efficiency of storage space in warehouses. was.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a packaging device that is small in size and volume, and that can sufficiently protect the magnetic tape.

Means for Solving the Problems In order to solve this problem, the packaging device of the present invention provides a core at the center of the magnetic tape roll, and a core of the magnetic tape roll between the top cover and the bottom cover. By providing a side plate that covers the outside, it is configured to be packable.

Function: With this configuration, conventionally, external pressure was received at the outer periphery of the case to prevent tape damage, but by supplementing the inner core and side plates, the case can be removed without deteriorating the protective function. It is something.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. Note that the same numbers are used for parts corresponding to those in the conventional example, and descriptions of duplicate contents are omitted.

FIG. 1 is an exploded perspective view according to an embodiment of the present invention. A donut-shaped sheet 5 with cushioning properties is placed on the bottom lid 8, and a wound body 3 made of magnetic tape 1 wound in a roll around the hub 2 is placed on top of it, and the sheet 5 is placed on top of the wound body 3. put.

Stack this up several times. A pipe-shaped core 9 is inserted into the center of the stacked wound bodies, that is, an inner cylindrical portion into which the reel shaft of the hub 2 is inserted, and an upper lid 10 is placed thereon. At this time, both ends of the core 9 are in contact with the bottom cover 8 and the top cover 10, respectively. Next, a side plate 11 made of corrugated paper or plastic cardboard is wound between the bottom cover 8 and the top cover 1o so as to cover the outer periphery of the rolled body 3, and fixed with an adhesive tape 12 or the like. Finally, as shown in FIG. 2, bind with a tight band 7.

With this configuration, even if external pressure is applied, as shown in FIG. 3, which is a cross-sectional view of the present invention, the side plate 11
With the center core 9, no pressure is applied to the wound body 3, and no tape damage occurs. FIG. 4 is a diagram showing the deformation of the wound body when pressure is applied without the side plate 11.

The side plate 11 also serves to protect the magnetic tape, which is particularly sensitive to dust, from the outside atmosphere.

Further, the core 9 suppresses movement of the wound body 3 in the circumferential direction.

Furthermore, since the wall thickness t1 of the conventional case 5 is eliminated, the height can be reduced by t1Xn, where n is the number of cases, compared to the conventional case.

Effects of the Invention As described above, according to the present invention, by providing the center core and side plates, tape damage does not occur due to external pressure, etc.
The case can be removed without degrading the protective function, drastically reducing material costs, and further reducing the overall volume, which has the advantage of greatly improving loading efficiency during transportation and storage space efficiency. have
