Abstract

PURPOSE:To prevent the collapse of stacked articles by a method wherein a pallet with articles stacked is placed on a rotary disk, the crepe paper rolled up on a vertically set roll is unwound therefrom, its end is fixed to the side of this article stack and the stack is wound with the crepe paper by rotating the rotary disk while it is being tensioned. CONSTITUTION:A pallet 6 with articles 5 stacked is supported on a rotary table 7 and crepe paper 9 is unwound from its roll 10 and attached to a suitable place of the article 5. The article stack is then wound with the necessary number of turns of the crepe paper 9 by rotating the table 7 while simultaneously applying a suitable braking force to the roll 10 to maintain the crepe paper 9 under tension. At this time, the article stack is evenly wound with the crepe paper 5 by moving the roll 10 up and down. After completion of winding with a specified number of the turns, the rotation of the table is stopped, the crepe paper 9 is cut off and its cut end is fixed to the article stack with a pressure- sensitive adhesive tape. In this way, even if the winding direction of the crepe paper 9 is deviated from the pulling direction, the stress localization resulting from the stretching force exerted on the crepe paper is avoided with no starting point of paper tear.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to prevent the collapse of a load by wrapping the side circumference of an object such as a heavy bag or a cardboard box on a pallet with crepe paper while the object is stacked. The present invention relates to means for preventing load collapse in integrated palletization.

2. Description of the Related Art In general, in order to prevent a load from collapsing a heap, a stretch wrap for tightening the load is widely used by utilizing the restoring force of the stretchable material, and a film is used as the stretchable material. In recent years, it has been considered to use paper as a stretchable material instead of a film because of increasing concern about environmental problems. However, it has not been put to practical use because problems such as strength have not been solved. In particular, when wrapping an item to be wrapped with paper and the flow direction of the paper and the pulling direction are misaligned and do not match, the force concentrates on one point of the paper and it is easily torn and should be wrapped. I can't.

The present invention is intended to solve the above problems by using crepe paper as a packaging material for stacks.

That is, the present invention provides a heavy bag,
TECHNICAL FIELD The present invention relates to a method of packaging a stack of articles such as a corrugated cardboard box that is stacked on a pallet and the side circumference of the stack is wrapped and wrapped with crepe paper to prevent collapse of the stack. In addition, the present invention stacks articles such as heavy bags and cardboard boxes on a pallet, places the pallet on a turntable, and rolls back the crepe paper wound in a roll direction with the width direction being the vertical direction to rewind the tip. Is fixed to the side circumference of the stack, and the crepe paper is wound around the side circumference of the stack while rotating the turntable and tensioning the crepe paper. The present invention relates to a method of packaging a product. Crepe paper is wet paper that is wrinkled with a doctor on a press roll, Yankee dryer, or the like. If you use crepe paper instead of normal paper for stretch wrapping, even if the flow direction of the paper and the pulling direction do not match, the stretch of the crepe paper avoids the concentration of force and is torn from there. Never.

There are two types of crepe paper production methods, dry crepe and wet crepe. Of these, dry crepe is applied to a paper sheet that has been dried to 85 to 90% with a Yankee dryer, and the paper quality is generally softer than that of wet crepe. Wet crepes are 34-38% wet paper webs that are creped on a Yankee dryer and then dried with several after dryers. The crepe paper used in the present invention may be either type of crepe paper.

In the present invention, the existing technique can be used for the method of winding and packaging a heavy load. Although illustrated below, it goes without saying that the present invention is not limited to this example.
FIG. 1 shows a method of wrapping by hand winding. Holding the winding cores 2H, 2L with respect to the stacked collection cargo 1 by hand, the crepe paper 4 wound up by the roll 3 is wound around the stack 1 as many times as necessary while applying tension. .. The starting end and the ending end are fixed by an appropriate means such as an adhesive tape. Second
The figure shows an example of automatic winding. The article 5 is a pallet 6.
It is stacked on top and is supported on a rotatable turntable 7. On the other hand, a pair of upper and lower holders 8H and 8L supported by a column 11 holds a roll 10 made by winding the crepe paper 9. The column 11 extends vertically and is fixed to the base 12. Holders 8H, 8L and roll 10
Can be raised or lowered along the column 11. A brake mechanism is attached to the roll 10 so that an appropriate tension can be applied when the roll 10 is rolled back. In order to package the article 5 in this apparatus, the article 5 and the pallet 6 are supported on a rotary table, the crepe paper 9 is unwound from the roll 10 and attached to the article at a proper position. After that, while rotating the table and simultaneously applying an appropriate brake to the roll 10 to tension the crepe paper 9, the article 5
Wrap crepe paper 9 around the required number of times. At that time, the position of the roll 10 is moved up and down to move the crepe paper 9
Are uniformly wound on the article 5. After the winding of a predetermined number of times is completed, the rotation of the stack is stopped, the edge of the crepe paper is cut with a cutter, and the tape is fixed with adhesive tape.

In the method of the present invention, while winding the side circumference of the stack with crepe paper, appropriate positions of the crepe paper are appropriately bonded and fixed with hot melt, vinyl acetate or another adhesive. Bonding may be such that the rolled crepe paper does not slip off, and therefore the bonding area may be negligible. In order to apply the adhesive to the crepe paper, the adhesive is sprayed in spots by, for example, a hot melt gun. The surface to which the adhesive is attached may be the front surface of the crepe paper wound up on the article, or the back surface of the crepe paper immediately before being rolled back from the roll and wound on the article.

EFFECTS OF THE INVENTION Since the present invention has the above-mentioned structure, it has the following effects. 1. The stretch of crepe paper avoids the concentration of force and it does not break. Therefore, the single heavy load item does not collapse. 2. It is possible to recycle crepe paper. It is easy because it can be incinerated even if it is discarded. 3. It is cheaper than a film.

EXAMPLES The present invention will now be described in more detail with reference to examples.

EXAMPLE 1 Two vertical and three horizontal corrugated cardboard boxes were stacked on a pallet in three stages and wound around a crepe paper made of kraft paper with a width of 600 mm while being tensioned. The key points were bonded and fixed with a vinyl acetate adhesive. I transported this pallet by truck, but there were no troubles such as load collapse.
