Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a disk packaging material used for automobile wheels, and more specifically, simplifies and compacts the disk packaging work and reduces the packaging cost. Moreover, the purpose is to facilitate the processing after unpacking.

(Prior Art) A wheel disc for an automobile is deep-drawn from a steel sheet and formed into a circular dish shape, and is conventionally stored or transported in a package as shown in FIG.

That is, the discs are put in a vinyl bag 2 for one sheet and packaged, and then sequentially stacked in a cylindrical carton 1 such as a corrugated board through a spacer 3 made of urethane foam.
As shown in the figure, a large number of leg portions 5 that can be transported by a forklift are loaded side by side on an iron plate tray 4 having four corners, and a corrugated cardboard insole 7 is further provided on the top thereof.
Similarly, a large number of the above-mentioned cylindrical cartons 1 were arranged on the upper part thereof, and a corrugated cardboard upper plate 8 was placed thereon, and these were integrally packaged by an angle member 6.

(Problems to be solved by the invention) However, in the case of the above packaging, not only the material cost is high, the workability of the packaging is poor, but also moisture is retained in the vinyl bag and the disc is easily rusted.

In addition, the cylindrical carton lacks stability and requires skill in stacking and loading, and since it uses angle materials, it easily bends when caught on the fork claws during loading and unloading,
In addition to the necessity of repacking, there is a problem in that it takes time for unpacking work and that it is difficult to process the packing material after unpacking.

(Means for Solving the Problems) The present invention aims to improve the conventional packaging described above to reduce costs, improve work safety and workability, and facilitate quality maintenance and disposal of used materials. Specifically, with respect to the shape-retaining sheet, a plurality of disk holding portions each having a recess having a diameter substantially equal to that of the disk and corresponding to a protrusion of the disk, and either of the front and back sides of the shape-retaining sheet. And an annular holding groove for holding the outer peripheral edge portion of the disk, which is concentric with the disk holding section and has two or more threads concentric with the disk holding section. The present invention relates to a packaging material for a wheel disc, which is formed by molding.

(Function) Since the shape-retaining sheet has a plurality of disc-holding portions having a diameter substantially equal to that of the disc and having recesses corresponding to the protrusions of the disc and substantially conforming to the shape of the disc, The disc holding portion has a concave R substantially along the curved convex R of the disc, and the convex R is supported by supporting the convex R of the disc, or the shape retaining sheet is inverted. The flange portion of the disk is engaged and held in an annular holding groove formed on the boundary between the disk holding portion and the disk holding portion adjacent thereto.

In addition, when storing and transporting a disc with a larger diameter, an annular holding groove, either concentric with one disc or two or more discs with different diameters, should be provided on the outer periphery centered on the disc holding part. The outer peripheral edge portion of the disk is fitted and held in the annular holding groove.

In this way, discs equal in number to the disc holding portions provided on one sheet of the mold-holding sheet placed on the pallet are loaded, and the upper surface of the disc-holding sheet is further covered by another mold-holding sheet. Stack them one after another and store or transport them as they are.

(Embodiment) The specific contents of the present invention will be described below with reference to the illustrated embodiment. Reference numeral 11 indicates a shape retention sheet, and 12 indicates a disk holding portion. The shape-retaining sheet 11 is made of a film such as polyethylene or vinyl chloride, or made of a cardboard or other material, and it is desirable that the shape-retaining sheet 11 has good retention after embossing and can be incinerated after use. .

The shape-retaining sheet 11 is provided with concave disk holding portions 12 having a diameter substantially equal to that of the disk D and substantially conforming to the cross-sectional shape corresponding to the convex portions of the disk, which are embossed at a plurality of positions that do not overlap each other. . That is, as shown in FIG. 2, the disc holding portion 12 has a curved concave portion 12a, a semi-ridged portion 12b, and a concave R portion 12c formed on one side of the shape-retaining sheet 11, and on the opposite side surface. The curved convex portion 12a ', the semi-recessed portion 12b', and the convex R portion 12c 'appear so as to be symmetrical with each of these portions.

Further, on the outer peripheral portion centering on each of the disc holding portions 12 described above, one concentric circular groove or two or more circular holding grooves 13 having different diameters are formed, thereby discs having a significantly different diameter. It enables the storage and transportation of.

Incidentally, the above-mentioned disc holding portion 12 and the annular holding groove 13
In the molding of, a known press die and a press machine can be used for shaping.

The above packaging material is laid on the upper surface of the pallet, and is formed concentrically with the curved concave R portion of the disc holding portion 12 provided on the packaging material and the outer peripheral portion around the disc holding portion 12. The curved convex portion R of the disc is fitted into one of the annular holding grooves 13 that is present, or the outer peripheral edge of the disc is held, so that the one with better disc holding stability is selected and shown in FIG. As described above, hold one of the discs in each disc holder with one side facing up,
Further, another disc wrapping material is overlaid on the upper surface, and the discs D are sequentially stacked and packaged.

(Effect of the Invention) The packaging material for the wheel disc of the present invention is as described above.
Since the shape-retaining sheet is formed by embossing a plurality of concave disc holding portions having a diameter substantially equal to that of the disc and having a cross-sectional shape substantially corresponding to the convex portion of the disc, the disc is curved. The protruding R portion is held by the R portion which is recessed in the disc holding portion of the packaging material, or the flange portion of the outer peripheral edge of the disc is molded on the outer peripheral portion centering on each of the disc holding portions. By the way,
By holding the disk holding portion in an annular holding groove that is concentric with the disk holding portion, the disk holding portion can be stably fixed.

Moreover, in this case, it can be applied to the storage and transportation of discs of slightly different sizes or shapes, and can significantly simplify the work, make the packaging compact, and reduce the packaging cost compared to conventional packaging. In addition, the packaging material itself can be reused even after unpacking, and post-treatment by incineration is easy.

Not only that, but also an annular holding groove for holding the outer peripheral edge portion of the disc, which is concentric with one disc or two or more discs having different diameters around the outer periphery of each disc holding part provided on the packaging material. Since the disk is formed, the range of application can be expanded for storage and transportation of discs whose diameters are considerably different from each other.
