Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to relatively easily deformable objects of the same type, such as those shown in FIGS.
The present invention relates to a method of stacking and transporting a plurality of plastic boxes 4 each having a tapered thin side wall 3 that gradually widens in the Q direction.

When the object to be transported is transported from the manufacturing site to an assembly factory or customer using a transport facility such as a truck, it is generally carried out in a relatively strong cardboard box, as shown in the third tooth. A box 6 called a backing case is used. Then, the boxes 4, 4a, which are the objects to be transported,
...is box 5 t 5 a + 5 b *60・
They are packaged individually and stacked for transportation, but at this time, box 6? ``Supports i-box 4, and''
This prevents the box 4 from deforming. However, the transportation method using the box 6 has various problems as described below.

0) Shipping costs will be high because the individual packaging will be larger by 60 minutes per box.

(2) Even though the box 6 is made of paper, it must be made strong, which increases the manufacturing cost.

(3) It is necessary to lift the box 4vl with respect to the box 6 to wrap and unpack it, which takes too much time and effort.

Regarding the above problem (■), manufacturing costs can be reduced by making the box 6 a pass-through type, but the return shipment will also require a large amount of shipping, just like the outbound shipment, and the transportation cost will be reduced. To increase. This transportation cost can be reduced by folding the box 6 to make it smaller on the return flight, but it requires the effort (labor cost) to fold it anew.

As a general solution, as shown in Fig. 4, only boxes 4 * 41 * 4 b * 40 are stacked and transported, that is, boxes 4 located below
One possible method is to immerse the lower part of the side wall 3 of the box 4a located above into the top opening 2, but this method does not require the above-mentioned immersion, and the side wall 3 of the box 4 located below is located above. box 4at 4b.

There was a problem in that the weight of 4C caused deformation and damage as shown in the bulge in FIG.

In addition, as a solution, as shown in Figure 6, box 4
A method has been proposed in which a rigid frame-shaped support 6 having a recessed center portion formed in the upper space 2 is bridged, and the recessed portion 7 of the support 6 is placed on the upper buttocks box 4. This method has various problems as described below: (1) The diameter of the recessed portion 7 of the support body 6 is constant.

If the diameter of the concave portion 7 of the support body 6 and the diameter of the bottom side wall of the box 4a are not matched, the box 4 will not fit into the concave portion 7 of the support body 6.
Since the bottom side wall of a does not fit in i, or there is a gap between the supporting body 60 and the mounting portion 7, resulting in misalignment, high precision is required in the manufacturing process, which increases the manufacturing cost.

(2) Since the support 6ti is a rigid body that cannot be rolled up into a small size, it is bulky and takes up space when not in use, such as when returning from transportation.

The present invention solves the above problems at once.
A ring-shaped support is wrapped from the bottom of the object to the top opening in the vertical direction, and the outer circumferential distance of the object facing the support is made somewhat longer. The objects to be transported are sequentially stacked and placed on a support body located in the upper opening of the transporter, and the lower side walls of the objects to be transported are recessed into the upper opening.

A support body which is one embodiment of the present invention will be described below with reference to FIGS. 7 and 8. The support 6 is made of a flexible material such as polypropylene 6beam, and has a ring shape slightly longer than the outer circumference of the opposing box 4. By winding the box 2 in the vertical direction, the support 6 located at the top opening 2 of the box 4 is bridged in a sagging state due to the restoring force, as shown by the solid line in FIG. When the box 41L is placed on the support 6, the support 6 receives the load shown by arrow A and is pulled along the bottom side wall of the box 4 as shown by the broken line. .

The tensile force indicated by the arrows prevents the side wall 3 from expanding and deforming.

In addition, since the supporting body 6 has a slightly longer outer circumferential distance than the opposing box 4, it is easy to wrap or remove it. Since the body is not required, the production cost can be reduced accordingly.

Furthermore, the support 6I/i is used as a reusable item, similar to the box 6 described in the conventional example, but when it is transported back for reuse, it can be rolled up into 6 pages, and returned to a large bag. Transportation costs can be reduced.

Figure 9! FIG. 10 shows another embodiment in which a cover 8 is formed separately from the support 6, and a temple cover 8/fi support is formed.
-There is 1 interposition between special holiday 6 and box 4. The cover 8 is made of relatively cheap polyethylene, that is, a polyurethane bar, and this cover 8 is simply attached to the box 4.
Since the cover is simply placed over the cover, it can be easily attached to and detached from the Nibox 4.

As described above, according to the transportation method of the present invention, when the objects to be transported are stacked, the support body follows the bottom side wall of the objects to be transported, so the bottom of the object to be transported does not fit into the support body as in the conventional case. There are no problems such as this, and the support is reliably supported, and since the support is slightly longer than the outer circumference of the object to be transported, it is easy to attach and remove the support.
In addition, there is no need for a locking member to connect the transported object and the support, which reduces manufacturing costs.Furthermore, when not in use, the support can be rolled up into a small size and stored, or transported back for reuse. This provides various effects, such as the ability to
