Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates primarily to an apparatus for packaging engine parts, such as cylinders, pistons, conrods, etc., in preparation for transportation or other purposes.

(Prior Art) Conventionally, this type of device is a type in which at least two trays made of styrofoam or other elastic materials are prepared and each part is housed in each recess on the top surface, and these are stacked one on top of the other for packaging. As is well known, in this case each part generally consists of a small part and a large part, and when the recess is made to have a relatively large diameter and deep bottom in preparation for storing large parts, each tray is placed opposite to this. This results in a relatively thick wall, and when a plurality of them are stacked, the overall length becomes high, which is a disadvantage.

(Problems to be Solved by the Invention) The object of the present invention is to obtain a device free from such disadvantages, that is, a device whose overall height does not increase due to the presence of large-diameter parts.

(Means for Solving the Problems) The present invention has been made based on this point of view, and includes at least a tray made of styrofoam or other elastic material for accommodating corresponding large and small assembly parts in each recess of the upper surface. In the case of a type that prepares two trays and stacks them on top of each other for packaging, each of the two trays has one part to match the tall large part, and the other part to match the thick part and the thin part to the small part. The convex part and the concave part formed in the thin part are fitted into each other at their opposing surfaces.

(Example) An example of implementing the present invention will be explained with reference to attached drawings. In the drawings, reference numeral 1 indicates a tray, and the tray 1 is made of styrofoam or other elastic material, and is of a type that accommodates each part a in each recess 2 on its upper surface.At least two of the trays 1 are prepared, and these are One set of packages 3 was obtained by stacking them one above the other.
In this case, the two trays 1, 1 have a projection 4 on one side and a recess 5 on the other side along the outer periphery of their overlapping surfaces.
The lower tray 1 has a recess 2 on the lower surface of the upper tray 1.
It is common to have respective recesses 6 for accommodating the upwardly protruding portions of the respective parts a within.

In the illustrated example, as shown in FIG. 2, for example, the trays 1 are provided in two upper and lower portions and two in the lower portion, and the four trays accommodate the assembly parts of one engine. For example, as shown in the first figure, a plurality of the packages 3 are stacked and housed in one package case.

Although the above is not particularly different from the conventional one, according to the present invention, the upper and lower trays 1 are constructed as follows. That is, first, the upper and lower two will be explained. For example, as shown in FIGS. 3 to 6, the upper tray 1 and the lower tray 1 are each formed into a thick part 7 and a thin part 8, resulting in a convex part 9 and a concave part 10. are fitted into each other on their opposing surfaces, and thus the recess 2 is formed in the thick wall portion 7 with a relatively large diameter and deep bottom, and the part a in the recess 2 can be used as a large part, e.g. A pulse generator can be used, and in this case both trays 1, 1 are fitted into each other by the protrusions 9 and the recesses 10 so that the height of the trays as a whole is not increased.

This is approximately the same for the two lower trays 1 and 1, as clearly shown in FIGS. 7 to 10, that is, the upper tray 1 and the lower tray 1 are At this point, the convex part 9 and the recess 10 formed in the thick part 7 and the thin part 8 are fitted into each other on their opposing surfaces, so that the recess 2 in the thick part 7 is relatively large. By obtaining a large diameter and a deep bottom, the part a can be used as a large part, such as an ACG cover or a fly hole.

(Function) The function is as described above, and both trays 1 and 1
The thick part 7 formed on one side of the tray acts to accommodate the large part a, and the thick part 7 has a convex part 9 and a recess 10 formed by overlapping with the thin part 8 formed on the other tray 1. They fit together and there is no increase in overall height.

(Effect of the invention) In this way, according to the invention, both trays 1, 1
The part a in the recess 2 can be made into a large part, and in this case, the thick part 7 is formed into a thin part in the other tray 1. The convex portion 9 and the concave portion 10 formed by overlapping with the convex portion 8 are fitted to each other, and there is no increase in the height of the package as a whole, and the packaging body can be made relatively compact.
