Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention belongs to the field of commutable units, specifically open containers whose bottom portions are split when loading and unloading high cargo.

(Prior Art) The present applicant previously proposed Utility Model Application No. 16584/1983 as a commuting unit of this type, which is as follows.

In other words, the main body consists of a bottom part that is approximately the same size as the pallet surface, making full use of the width of the original fabric, and side parts on both sides of this in the length direction of the original fabric. Divided widthwise from the center,
Both edges are folded back and hooks are provided at both ends, and a connecting belt with hooks at both ends is provided obliquely so that half of its tip protrudes from the edge. In addition to providing an insertion part for the fork claw at the end of the face part, a suspension belt that also serves as a bottom holder is inserted through these insertion parts.To join the two divided bottom parts, a bottom connection belt with a hook is used. Insert the slanted parts of the above into the folded parts of the opposing edges through the center notch, and insert the above-mentioned suspension belt that also serves as a bottom holder into the hooks at both ends of the connecting belt with hooks and the hooks at both ends. They are inserted into each other and tied and connected to each other.

(Problems to be solved by the invention) In the case of such a proposed return unit, when using it, when loading nearly 1 ton of baggage, cardboard boxes, etc., and lifting it with a forklift, due to the load. , the joint surface of the bottom part tends to open in the middle, and the packaging is not necessarily satisfactory, and the hanging belt that also serves as a bottom holder, which is inserted through the insertion part, is not suitable for inserting fork claws. Therefore, it was inevitable that the position would shift and give a feeling of instability.

(Means for solving the problem) In view of the above points, the applicant has decided to
As a result of repeated experimental tests of the opening phenomenon of the joint connection at the bottom with 1 ton of cargo loaded high, we were able to ensure the safety of the bottom and the stability of the packaging, so we filed an application for this invention. This is what I came to do.

In other words, the connection means by the belt with hooks for bottom connection sewn along both dividing edges of the divided bottom part is connected to the connecting means between the joining both side edges of the divided bottom part and the middle between the joining both side edges. The problem was solved by connecting the bottom holding belt to the fork claw insertion part side and sewing it on.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

The returnable unit A of the present invention uses a raw fabric woven from flat yarns such as polyethylene and polypropylene, and is shown in Figures 1 and 2 (the back side is shown for ease of understanding). As shown in FIG. 2, it is made up of a bottom part a which is approximately the same size as the pallet, making use of the entire width of the original fabric, and side parts b ₁ and b ₂ that extend in the length direction of the original fabric.

The bottom part a is divided from the center in the width direction of the original fabric.
a ₁ , a ₂ , and on the edge side of the divided bottom part a ₁ is a bottom connecting belt 2 with large ring-shaped hooks 1 and 1' at both ends, and a reinforcing belt 3 in its center. , 3' are sewn together,
Hook stops 4, 4' through which the hooks 1, 1' can be inserted are sewn to both ends of the edge.

A bottom connecting belt 6 with hooks 5 and 5' at both ends is sewn to the edge side of the divided bottom part _a2 at a distance x from the edge, and this A reinforcing belt 8 with a hook 7 and a reinforcing belt 8' with a hook 7' are sewn on the top in a cross shape. In this case, belts with hooks 8, 8'
The distance between the reinforcing belts 3 and 3' is wider than the distance between the reinforcing belts 3 and 3', and the hooks 7 and 7' are arranged within the overlap width x.

Hooks 7, 7' of belts 8, 8' with hooks,
The connecting portion with the bottom connecting belt 2 with hooks is located at the intermediate portion between the hook stops 4, 4' and the reinforcing belts 3, 3' at the dividing edge.

Bottom part a [bottom part a ₁ ,
a ₂ ], the side surfaces b ₁ and b ₂ on both sides are on the bottom a.
The length is suitable for stacking 20 to 30 kg of small bags or cardboard boxes B [hereinafter referred to as "cargo B"], and the end of the tube has a tube into which the fork claw C of a forklift can be inserted. Shape-shaped insertion portions 9 and 10 are formed by folding back and sewing the ends, and these insertion portions 9 and 1
On the side edges 11, 11' and 12, 12' of 0,
Suspension belts 13, 13' and 14, 1 for holding the bottom
4' is sewn to reinforce this part.

On the side edges 11' and 12', the sewn parts of the folded parts are located inside in the width direction of the original fabric so that the fork claws can be easily inserted.

Reinforcement belts 17 and 18 are sewn to the folded sewn parts 15 and 16 of the insertion parts 9 and 10 of the fork claw C up to the side edges, and one end thereof is
The ring-shaped upper temporary fixing hooks 19 and 20 have their other ends extending to upper temporary fixing belts 21 and 22.

In addition, 23 and 24 are the bottom part a ₁ , the side part b ₁ , and the bottom part
This is the boundary between a ₂ and side surface b ₂ .

In order to join and connect the bottoms _a1 and _a2 of the above configuration to form the commutable unit _A , the unit in the state shown in Fig. At the same time, the hooks ₁ and 1' at both ends of the bottom connection belt 2 with hooks on the bottom a ₁ side are connected to the reinforcing belt 8 with hooks on the bottom a ₂ side.

and 6 hooks 1, 5 and 1', 5'.
With this, commuting unit A is completed.

When using the commutable unit A in the state shown in FIG. 1, it is turned over and placed, for example, on a pallet of a palletizer.
Since the bottom surface portion a is approximately the same size as the pallet, it extends over the entire surface of the pallet.

Next, load B weighing 20 to 30 kg is piled high on the bottom part a using a machine. At this time, it is better to take care so that the joint surfaces of the lowest load B do not lie on the joint line of the bottom parts a ₁ and a ₂ .

The side parts b ₁ and b ₂ are made to stand up from the boundary parts 23 and 24 along the sides of the loaded cargo B, and the side parts b 1 and b 2 are
Attach the upper temporary fixing belt 22 on the side part b ₂ side to the upper temporary fixing hook 19 on the b ₁ side, and attach the upper temporary fixing belt 21 on the side part b ₁ side to the upper temporary fixing hook 20 on the side part b ₂ side. Insert and tie each.

Next, the suspension belts 13 and 14 are placed on the hooks 1 and 5, and the suspension belt 1 is placed on the hooks 1 and 5.
3' and 14' are tightened and tied on the hooks 1' and 5', respectively.

At this point, as shown in FIG. 3, the suspension belts 13, 14 and 13', 14' are in a state where they are holding the bottom part a, and the unit packaging A' is completed.

To transport such a unit package A′,
Insert the fork claws C of the forklift into the insertion portions 9 and 10 of the side surfaces b ₁ and b ₂ of the unit body. Since the length of the fork claw C substantially matches the width of the original fabric, the unit package A' can be lifted in a stable state.

The loaded baggage B is lifted by the fork claws C, and its sides are pulled inward by the side parts b ₁ and b ₂ , and the bottom part a is pulled up by the hooks sewn to the bottom parts a ₁ and a ₂ . The hanging belts 13, 14, 1 which are used to hold the bottom are inserted through the hooks 1, 5, 1' and 5' of the bottom connecting belts 2 and 6, and are tightened and tied.
3' and 14'.

By this pulling up, the hooks 1 and 1' of the bottom connecting belt 2 with hooks pass through the hooks 7 and 7' of the reinforcing belts 8 and 8' with hooks,
Furthermore, since hooks 4 and 4' are inserted,
The joint between bottom parts _a1 and _a2 does not open, and there is no sagging in the bottom part a as a whole, which makes it tight and stable in the appearance of the package.

The above-mentioned high stacking work using a palletizer is done mechanically, and while the items are coming out in the assembly line,
Since manual auxiliary work can be easily completed, the unit packaging that comes out of the palletizer
A′ can be directly truck loaded, leaving pallets to increase production.

Furthermore, if a storage period is required, the unit packages A' can be stored in a warehouse with the unit packages A' set on pallets, and the unit packages A' can be transferred to trucks as needed.

Next, the work of unloading the unit package A' is carried out, for example, by inserting the fork claws C into the tube-shaped insertion parts 9 and 10 of the unit package A' placed on the pallet. While untying the upper temporary fastening belts 21 and 22 on both sides, the bottom holding belts 13 and 22 on both sides are untied.
14, 13', and 14' are untied, and pulled out from the hooks 1, 5, and 1', 5'.

Next, when the fork claws C are raised, the power of the suspension belts 13, 14 and 13', 14' to hold the loaded baggage B is lost.
The entire weight of the baggage B will be received by the bottom part a, and in this bottom part a, the hooks 1 and 1' of the bottom connecting belt 2 with hooks are simply the hooks 7 and 1 of the reinforcing belts 8 and 8' with hooks. 7' and hook stops 4 and 4', it cannot withstand the load, and the bottom connecting belt 2 with hooks is not able to withstand the load.
The hooks 1 and 1' are removed from the hook stops 4 and 4' and the hooks 7 and 7', and the bottom parts _a1 and _a2 are separated from their joints and open on both sides, and are pulled out from the bottom surface of the baggage B. The piled-up cargo B remains in the form of a pallet without changing its packaging shape.

(Effects of the invention) The commutable unit of this invention can be used to load parcels of 20 to 30 kg in small bags or cardboard boxes.
This system aims to streamline cargo handling such as loading, unloading, and transshipment.
The unit main body made of raw fabric is divided in the width direction of the raw fabric at the bottom part, a bottom connecting belt with hooks is sewn along the edges of both divisions, and the hook parts at both ends of these belts are sewn. , this hook part and the bottom-holding suspension belt are inserted and tied together, and both free ends of one of the bottom connecting belts with hooks are connected to the hooks of the cross-shaped reinforcing belt from the other side in the middle of the dividing edge part. Since the connected bottom part is connected and held at both side edges of the divided edge part and the middle part, it is possible to connect the unit with high loads. When the packaging is lifted by inserting the fork hook into the insertion part, the unit body made of the original fabric becomes a single unit through the cooperation of the hook-equipped bottom connecting belt and the bottom-holding suspension belt. The connecting part at the bottom part opens and the inside does not become sagging, and the package is kept in a stable state without collapsing.

In addition, since the suspension belt that also serves as a bottom holder is sewn on the side where the fork claws are inserted, when lifting a unit package, it will not move or shift due to the insertion of the fork claws, which also prevents the package from collapsing. There's no danger of it happening.

In addition, when unloading or transshipping work, simply leave the fork claws inserted, untie the upper temporary fastening belt, untie the bottom lifting belt, and raise the fork claws. Since the unit body can be removed from the loaded baggage without changing its appearance, there is no need to move the forklift and insert the fork claw into another hanging belt or the like.

Moreover, since the structure as a whole is simple and the width of the original fabric is used as is, it is easy to handle and can be provided at low cost.
