Abstract

PURPOSE:To provide a packing method by which sheets loaded on a pallet base are not shifted during transportation and they are unpacked well. CONSTITUTION:A stretch film 11 is wound up from a spot 1 to spots 2, 3, 4, 1 in this order by at least one or more rounds so as to lie across both bottom sides of a pallet base 9 and loaded sheets 10. Subsequently, the film is diagonally stretched to a spot 6, one of corners of the upper side of the loaded sheets 10 and then laterally stretched to the spot 7 and also diagonally stretched from the spot 7 to the spot 4. After it has been wound up again around the periphery of both pallet base 9 and bottom side of the loaded sheets 10, from the spot 1 to the spots 2, 3, it is diagonally stretched from the spot 3 to the spot 8 and then laterally stretched from the spot 8 to the spot 5 and further diagonally stretched to the spot 2 and finally wound around both parts again in the order 3, 4, 2 at least one time or more times. In this way, the loaded sheets 10 and the pallet base 9 are prevented from falling or mutually shifting and hence, the protection of products is improved, the cost is lowered, and the packing and unpacking works are simplified.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing method for carrying laminated sheets, and more particularly to a packing method for laminating and carrying sheets on a forklift pallet stand.

[0002]

2. Description of the Related Art Conventionally, since a laminated sheet is transported by a forklift, the sheet is stacked on a pallet base for a forklift, and then a top plate is placed on the top of the pallet mount to stack the pallet base with a belt or the like. A packing method for binding the sheet is used.

However, in the above-mentioned packing method, since the band made of synthetic fiber or iron is used, the processed lumber and the top plate such as plywood are indispensable and expensive to protect the product, and the band is made of stretch film. In comparison, since it has no elastic force and is rigid, the product is often damaged or deformed when trying to strengthen the binding. Further, there is a drawback that the unpacking work is complicated at the warehouse or the customer.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art. The laminated sheet on a pallet does not collapse during transportation, and the workability is good even during unpacking. The purpose is to provide a simple packing method.

[0005]

Therefore, as a result of intensive studies to solve these problems, the present inventors have made the stretch film straddle both the pallet base and the bottom of the laminated sheet at the start. After wrapping, the four corners of the upper side of the laminated sheet are continuously laid at least once, and both the pallet base and the bottom of the laminated sheet are wound again. By these methods, It is possible to prevent the laminated sheets from collapsing from the pallet base or the laminated sheets from slipping together (preventing collapse of loads), and at the same time improve product protection, reduce costs, and simplify packaging and unpacking operations. The present invention has been achieved by finding out what can be done.

A method of packing laminated sheets on a pallet table according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state in which a laminated sheet on a pallet stand of the present invention is wrapped around with a stretch film.

For the sake of clarity, the corners (hereinafter referred to as points) in the final state in which the sheets are stacked on the pallet table are point 1, point 2, point 3, point 4, and point 4 from the bottom. Continue to the upper part, point 5, point 6, point 7,
Each number at Point 8 is shown.

First, the stretch film 11 is wound from the point 1 so as to straddle both the pallet base 9 and the bottom of the laminated sheet 10, and the point 2 → point 3 → point 4 → point 1
-2 (Point 1-2 indicates the second passage of the point,
The number of passes is indicated by a number. ) In order of at least one turn.

Subsequently, the laminated sheet 10 is hung on the point 6 which is one of the corners of the upper side, and then laterally laid on the point 7 in this order, and then laid on the point 4-2 from the point 7 to the point 4-2. From the point 1-3 → the point 2-2 → the point 3-2, the pallet base 9 and the bottom of the laminated sheet 10, and after going around both parts again,
From point 3-2 to point 8, side 8 to point 5, side 5 to point 2-3, and finally both parts again point 3-3 → point 4-3 → Wind up at least one round at points 1-4 to finish. The winding order is not particularly limited to this, but from the opposite direction,
Alternatively, in order to increase the strength, each winding sequence may be partially wound several times.

As a result, the laminated sheet 10 and the pallet base 9 can be prevented from collapsing or the sheets can be displaced from each other (load collapse prevention), and at the same time, product protection can be improved, cost can be reduced, and packing and unpacking operations can be performed. A simplification can be achieved.

The stretch film 11 used in the present invention may be wrapped around the whole in consideration of prevention of wetting, but in the case of the present invention, it is sufficient that four corner portions of the uppermost side portion are laid on each other. Is. Further, the width of the stretch film 11 is not particularly limited, but it is sufficiently possible to straddle both the pallet base 9 and the bottom portion of the laminated sheet 10, and even if the corner portions are hooked. It does not matter if it is a level that does not shift.

Stretch film 1 used in the present invention
As the material of 1, a known material such as polyethylene or polypropylene can be appropriately used. The stretch ratio of the stretch film is preferably 150 to 350%. The sheet used in the present invention may be a stack of sheets, or may be a package in which a fixed amount is packed.

The packing method of the present invention is not particularly limited to the size of the sheet, and can be applied not only to the sheet but also to any product that is transported by being stacked on the pallet stand 9 for forklift trucks. , If necessary, a top plate such as paper or film can be applied for the purpose of protecting the uppermost upper part.

[0014]

Operation: Both the pallet base 9 and the laminated sheet 10 are wrapped with the stretch film 11, then the four corners of the upper side portion of the laminated sheet 10 are sewn at least once, and the bottom portion is wound again. This prevents the stacked sheets from collapsing from the pallet base or the stacked sheets from slipping together (preventing collapse of loads), and also improves product protection, lowers costs, and simplifies packing and unpacking operations. Can be achieved.

EXAMPLES The effects of the present invention will be described below with reference to examples to further clarify them.

EXAMPLE 1 127.9 basis weight on a wooden pallet stand for a forklift
g / m ² · Chrysanthemum vertical format A2 coated paper (Mitsubishi Paper Mills: brand name'Pearl Court A ') is stacked 10,000 sheets, and a stretch film with a width of 300 mm (Nitto Sangyo: Brand name'S stretch) As shown in FIG. 1, using the film '), the pallet base and the bottom of the product are stretched from the point 1 and stretched to 200% to 300%, and then wound.
→ Point 2 → Point 3 Point 4 → Point 1-2 → Point 6 → Point 7
→ Point 4-2 → Point 1-3 → Point 2-2 → Point 3-2 →
Point 8 → Point 5 → Point 2-3 → Point 3-3 → Point 4-3
→ Wrapped around points 1-4 and packed. Next, the above-mentioned packed packages are stacked on a 10t truck at a speed of 20km / h.
At the end of the road, I made a sharp brake at 20 km / h, but it was confirmed that there was almost no load collapse and the initial condition was maintained.

Example 2 In Example 1, the stack of 10,000 sheets was replaced with an A2 coated paper having a basis weight of 104.7 g / m ² and a chrysanthemum vertical format.
(Mitsubishi Paper Mills: trade name'Pearl Coat A ') 250
The same procedure as in Example 1 was performed except that 40 packaged pieces were used. As a result, as in Example 1, there was almost no load collapse and the initial state was maintained.

Comparative Example 1 In Example 1, the pallet base and the bottom portion of the laminated sheet were stretched to 200 to 300% while being stretched over, and wrapped around. The rolls were wound up to the top so that the total length was the same as in Example 1. Similarly, as a result of stacking and evaluation on a truck, a portion of about 10 cm from the upper portion bulged by about 1 cm, and it was necessary to arrange the collapse of the load during printing.

Comparative Example 2 The uppermost part of the sheet product laminated in the same manner as in Example 1 had a thickness of 5
mm corrugated cardboard was placed, and the pallet base was fastened together with a synthetic fiber strip having a width of 10 mm at one place in the vertical direction and two places in the horizontal direction. As in Example 1, as a result of being stacked on a truck and evaluated, the whole was badly collapsed like a parallelogram, and the commercial value was remarkably low.

Comparative Example 3 In Comparative Example 2, about 1 cm from the top (about 100
Up to about 10 sheets), they were tightly tightened with a synthetic fiber band and packed in the same manner. Similarly, as a result of stacking evaluation on the truck,
Although not as severe as in Comparative Example 2, the load collapse occurred, and it was necessary to considerably arrange the paper during printing. Also, the upper 1 cm could not be made into a product.

[0021]

As described above in detail, when the packing method of the present invention is used, it is possible to prevent the laminated sheet and the pallet table from collapsing even during transportation, or the sheets in the laminated sheet from slipping together (load collapsing). In addition, the protection of the product can be improved, the cost can be reduced, and the packing and unpacking work can be simplified.
