Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging tray used for storing or transporting connecting nails driven by an automatic nailing machine.

Conventionally, as an example of the above-mentioned connecting nail, a connecting nail 1 wound in a spiral shape as shown in FIG. 1 has been widely known.

2 is a single nail, with the head 3 of the disc body of the nail facing upwards, the tip 4 of the nail facing downwards, and the middle part of the nail 2 being temporarily held at two points using, for example, two wires 5 and 6. It is fixed and connected as a whole in a band-like manner and wound in a spiral shape.

At this point, the spiral state would collapse and it would be impossible to fill the magazine of the automatic nailer, so up until now, the outer periphery of the connecting nail 1 was held with a holding member such as a rubber band (not shown), and in that state,
The connecting nail 1 was stored in a housing for storage or transportation.

Furthermore, when using the connecting nails 1, these casings are brought to the work site, the connecting nails 1 are taken out from the casings, the rubber bands are removed, and the magazines are filled.

However, when the spirally wound connecting nail 1 is housed in a casing or the like as shown in FIG. 21, and moreover, the tip 4 of the nail is in contact.

That is, the total weight of the connecting nails 1 is smaller than that of the nails 2 on the outer periphery.
It is in a state where it rests on the sharp tip 4 of 1.

For this reason, until now, the bottom part 7 of the casing etc. has been damaged while the connecting nail 1 is being stored or transported.
It was also dangerous.

In particular, this problem often occurs when housings containing a large number of the connecting nails 1 are further stacked for storage or transportation.

Furthermore, if the bottom part 7 of the casing or the like is formed of styrofoam or the like, the nail tips of the connecting nails 1 are pushed into the bottom part 1, so that the stacked state of the connecting nails 1 is not correct. New problems have arisen, such as non-uniformity and inconvenience in taking out the connecting nails 1.

In addition, the connecting nails 1 wound in a spiral shape are not wound around the central part 8 with a core (in order to fill the magazine of an automatic nailer and match the internal structure of the magazine). Since the space 9 is formed in the center, there is also the problem that the winding state of the nail group in the center is disturbed.

Therefore, the present invention has been proposed in view of the above circumstances, and it is an object of the present invention to enable the connecting nail to be stored and held in a predetermined wrapped state without using a holding member such as a rubber band as in the past. The purpose is to

Another object of the present invention is to prevent damage to the connecting nail storage section during storage or transportation of the connecting nails.

Furthermore, the present invention is directed to a plow that allows connecting nails to be stacked in multiple stages in a stable manner.

That is, the packaging tray of the present invention has a cylindrical shape that is open at the top and has a bottom at the bottom, and the inner diameter of the peripheral wall portion is approximately the same diameter as the diameter of the spirally wound connecting nails. The upper surface of the bottom part is configured to have a conical shape that is gradually raised upward toward the center with substantially the same slope as the conical shape formed by the tip of each nail of the connecting nail, The lower surface of the bottom has a conical shape that is inclined at approximately the same angle as the conical shape formed by the head of each nail of the connected nail, and gradually rises upward toward the center. A feature of the present invention is that these storage sections are connected and fixed via a flange formed above the peripheral wall so that a large number of storage sections are arranged and fixed in a multi-row, multi-column configuration.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

FIG. 3 is a longitudinal sectional side view showing a state in which the packaging trays of the present invention are stacked in multiple stages, and FIG. 4 is a plan view of the packaging tray.

This packaging tray 18 has connecting nails 1 wound in a spiral shape.
A large number of connected nail storage sections 10, 10, . . .
These storage sections 10, 10, . The peripheral wall portion 11 is connected and fixed via a flange portion 12 bent at a substantially right angle.

Each of the storage parts 10, 10, . . . is formed into a cylindrical shape by a peripheral wall part 11, and the upper part thereof is open so that the connecting nail 1 shown in FIG. 1 can be taken in and out.

The inner diameter of the peripheral wall portion 11 is approximately the same as the diameter of the connecting nail 1.

A bottom portion 13 is formed below the peripheral wall portion 11, and upper and lower surfaces i3A. , 13B have a conical shape with a central portion 14 raised upward.

In this embodiment, each of the storage sections 10, 10, . . . is described as having a cylindrical shape; It's okay.

A flat portion 15 is formed on the upper surface of a central portion 14 of the bottom portion 13, and the central portion 14 is formed into a substantially cylindrical shape.

Note that the conical shape of the bottom portion 13 may not have a flat surface in the center.

In the present invention, each of the storage sections 10, 10, . . . may be modified in various ways without impeding its purpose;
The slope of the conical shape of the upper surface 13A is substantially the same as the slope of the conical shape formed by the tip 4 of the nail 2 of the connecting nail 1.

Therefore, the inclined state of the upper surface 13A of the bottom portion 13 may be either a planar inclined state or a curved inclined state, and the tip portion 4 of the nail 2 is formed when the upper nail 2 is wound in a spiral shape. It is sufficient if it approximately matches the slope.

Further, the slope of the conical shape of the lower surface 13B of the bottom portion 13 is approximately the same as the slope of the conical shape formed by the head 3 of the nail 2 of the connecting nail 1.

Therefore, the inclined state of the lower surface 13B of the bottom portion 13 may be either a planar inclined state or a curved inclined state, and the head portion of the nail 2 is
It is sufficient if the slope substantially coincides with the slope formed by.

The packaging tray 18 of the present invention is constructed as described above, and is most easily formed by press working.

The material for forming the packaging tray 18 may be a metal body, such as an aluminum plate, a thin iron plate, or any material that can be pressed, such as pulp, paper, or plastic.

According to the structure of the packaging tray 18 of the present invention, it can also be made of styrofoam.

In particular, when molding is performed using calcium carbonate and olefin resin alone or a mixture thereof, since these materials are easily combustible, there is no pollution even if they are disposed of by incineration.

In addition, it has high mechanical strength, is lightweight, and has good water resistance, making it extremely effective as a storage body.

In addition, it can be cooked, has good workability and printability, and has various effects.

Therefore, the spirally wound connecting nails 1 as shown in FIG.
..., since the conical shape formed by the tip 4 of each nail 2 of the connecting nail 1 and the conical shape formed by the bottom 13 of the storage section 10 are formed with the same slope, all The tip 4 of the nail 2 is attached to the bottom 13 of the storage section 10.
The nails 21 on the outer periphery are abutted and supported from the side by the peripheral wall 11 of the storage section 10, and the connecting nails 1
Since a part of the bottom part 13 of the storage part 10 is inserted into the space part 9 of the central part 8 of the nail, the connecting nail 1 can be kept in a stable state without being unrolled even if it is not held with a rubber ring or the like. In addition, the total weight of the connecting nails 1 is distributed and evenly applied to the bottom 13 of the storage section 10, and the tip 4 of each nail 2 is pushed out. No problem.

Therefore, damage to the packaging tray 18, especially the bottom portion 13 of the storage section 10, can be prevented.

Moreover, the packaging trays 18 containing the connecting nails 1 can be stacked in a stable manner in multiple stages.

Note that when the trays 18 are stacked in multiple stages, the collar 12 of the tray 10 serves as a mounting base for the stacked trays 18, and the head 3 of each nail 2 of the connecting nail 1 is placed on the bottom 1.
3, so that they can be stacked in a stable state and held.

Further, the flange 12 increases the mechanical strength of the tray 18, and the lower flange 12 slightly enters the space 11 between the upper peripheral walls 11. , stacked upper trays 18
can prevent lateral displacement.

As described above, the packaging tray 18 having the above structure not only allows many connecting nails 1 to be stored in a well-aligned manner, but also increases the strength of the storage section 10 itself, which is advantageous when storing or transporting the packaging tray 18. Not only that, but if many storage units 10 are assembled to form a packaging tray 18,
Not only can this be placed on a flat surface, but it can also be placed tilted sideways.

Further, in the case of the above-mentioned embodiment, one storage section 10 is configured and arranged so that it is always at the position of the apex angle of the regular hexagon along with the other storage sections 10.

At this time, one of the storage parts 10 is arranged so as to depend on the center part.

By arranging the structure in this way, it is possible to arrange the largest number of storage sections 10 in a small area, and when it is laid down horizontally, it can be in a state with the highest mechanical strength.

As is clear from the above description, according to the present invention, the connecting nail can be stored and held in a predetermined wound state without using a holding member such as a rubber band as in the conventional art.

Therefore, it becomes easy to replenish the magazine of the automatic nailer with connecting nails.

Furthermore, according to the present invention, the nail tips of the connecting nails do not stick to the bottom of the container, and the entire weight of the connecting nails can be distributed and held. It is possible to reliably prevent damage to the packaging tray during transportation, and is extremely effective in practice.

Furthermore, the connecting nails can be stacked in multiple stages in a stable state.
