Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a packing method for transporting flat sheets after papermaking, and more specifically, to a ream unit packaging of flat sheets on a pallet table for a forklift. This invention relates to a packing method for stacking and transporting.

《Prior art》 Conventionally, the transportation of flat sheets involves transporting and loading work using a forklift. A packing method is used in which a top plate is placed on the top and the pallet table and ream stack are bound together with iron bands (iron band-shaped binding material).

However, in the above packing method, iron bands are used, so a top plate made of processed lumber or plywood is essential and expensive to protect the product.In addition, iron bands have no elasticity and are rigid, so they cannot be tied together. Attempting to strengthen the material often damages or deforms the product.
Further, when unpacking at a warehouse or a customer's site, tools such as a metal cutting iron are required to cut the band iron, which is disadvantageous in terms of workability.

<<Problems to be Solved by the Invention>> Therefore, as a result of intensive studies to solve the above problems, the present inventors found that when the ream and pallet table are temporarily fixed with double-sided adhesive tape, This prevents the reams from shifting from the pallet table, making it possible to use adhesive tape that is weaker than iron strips, and also allowing the use of adhesive tape to bind adjacent reams together. By wrapping only the lower stacked part with stretch film, it is possible to sufficiently prevent the lower stacked part from slipping, which improves product protection, lowers costs, and simplifies packaging work. The present invention was achieved by discovering that posture maintenance (prevention of load collapse) can be improved.

Therefore, an object of the present invention is to provide a flat sheet packing method that is excellent in the pallet table, the reams, the cohesion between the reams, the protection and preservation of the flat sheets, the economic efficiency and workability of packing, etc. .

<Means for Solving the Problems> The above-mentioned object of the present invention is to provide a packing method by stacking reams in which flat size units are packaged on a pallet stand for a forklift. After pasting double-sided adhesive tape at the required locations, stack the reams to the desired height, apply cardboard to the top, and bind the required locations on the sides of the reams from the cardboard to the pallet table with adhesive tape as appropriate. This was achieved by a flat packaging method characterized by wrapping a stretch film around the bottom stack.

The flat packing method of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a perspective view of reams tied together using the flat packing method of the present invention.

FIG. 2 is a perspective view showing an intermediate process of the flat packing method of the present invention.

FIG. 3 is a perspective view showing an intermediate process of another embodiment of the flat packing method of the present invention.

In the figure, reference numeral 1 indicates a pallet stand for a forklift.

Reference numeral 2 denotes a double-sided adhesive tape attached to the top of the pallet table 1. The double-sided adhesive tape 2 can be appropriately selected from known materials. In the case of ream wrapping paper whose outer surface is laminated with synthetic resin, the adhesive strength of the double-sided adhesive tape 2 is
The bond between the ream 3 and the ream 3 is stronger, and the double-sided adhesive tape 2 will not stick to or damage the ream 3 when removing the lowermost ream 3 from the pallet table 1. If you use tape that has strong adhesive strength on the pallet table 1 side and weak adhesive strength on the ream 3 side, the double-sided adhesive tape will not peel off from the pallet table even if the ream wrapping paper is not laminated with synthetic resin on the outer surface. It does not stick to the ream wrapping paper side or damage the ream wrapping paper due to the adhesive force of the double-sided adhesive tape. Furthermore, by making the tensile strength of the support of the double-sided adhesive tape 2 weaker than the strength of the ream wrapping paper, the adhesive tape is destroyed before the ream wrapping is destroyed during unpacking, so the ream wrapping can be protected. .

Such a double-sided adhesive tape has a strong adhesive of acrylic or rubber having an adhesive strength of about 750 (g/25 mm) or more on the back side of the base paper, and a strong adhesive of 80 to 250 g/25 mm on the other side of the base paper. A special removable acrylic adhesive with an adhesive strength of (g/25 mm)
43394 and 61-49350) are known. When using such a double-sided adhesive tape, in order to make it into a tape shape that is easy to use, it is necessary to laminate unstretched polypropylene with a thickness of about 80 μm or polyethylene on both sides of paper on the surface of the special adhesive. It is preferable to attach a release paper coated with silicone to the upper surface of the substrate.

The above is an example in which the reams are stacked directly on the top surface of the pallet table 1, but if the pallet table is made of wood and its surface is dirty, the third
As shown in the figure, it is also possible to affix the double-sided adhesive tape 2 to the required location on the upper surface of the pallet table 1, then place the paper 10 thereon, and then affix the double-sided adhesive tape 11 on top of the paper 10, and then laminate the ream 3. . In this paper 10,
For example, manila balls (160 g/m ² ) can be used. If the pallet stand 1 is made of paper or resin, it is not necessary to use this paper.

Reference numeral 3 is a ream in which flat sheets are packaged in units.
The packing method of the present invention has no limitations on the size of flat sheets, and can be applied not only to flat sheets but also to all products that are stacked on a pallet table and transported.

Reference numeral 4 is a cardboard box that is placed against the top of the ream 3 at the top. The cardboard 4 can be appropriately selected from known materials, but one single-layer cardboard sheet is sufficient. The cardboard box 4 used in the present invention is for protecting the upper part when stacking reams, so other materials may be used as long as the purpose can be achieved, and the shape may also be changed. Optional.

Reference numeral 5 denotes a binding adhesive tape, which can be appropriately selected from known materials such as craft tape.

Reference numeral 6 denotes a stretch film that is appropriately wrapped around the lower part of the ream. The stretch film 6 can be appropriately selected from known materials such as polyethylene and polypropylene.

Hereinafter, the flat packing method of the present invention will be explained in detail with reference to FIG.

First, double-sided adhesive tape 2 is applied to the required locations on the upper surface of pallet table 1. The double-sided adhesive tape 2 may be attached at any desired location, but it is usually sufficient to attach the double-sided adhesive tape 2 at two locations near both ends as shown in FIG.

Next, move the ream 3 to the pallet stand 1 to the desired height.
After stacking on top and applying cardboard 4 to the top,
Necessary locations on the side surfaces of the ream 3 extending from the cardboard boxes 4 to the pallet table 1, preferably two or more locations on each side, are appropriately and continuously bound with adhesive tapes 5. Although FIG. 1 shows the case where the four sides are bound at two places each with the adhesive tape 5, the present invention is not limited to this as described above, and the present invention may be bound at several more places as necessary. You can also do it.

Finally, the stretch film 6 is wrapped around the bottom stack. The stretch film 6 may be wrapped around the entire stretch film 6 to prevent it from getting wet, but in the case of the present invention, it is sufficient to wrap only the bottom layer.

<<Function>> As described above, in the flat packaging method of the present invention, the double-sided adhesive tape 2 is pasted on the top surface of the pallet table 1 to temporarily secure it to the bottom layer ream 3.
Misalignment between the pallet stand 1 and the ream 3 is prevented.

In addition, since the adhesive tape 5 is used as a binding means, there is no need to use a top plate as is required when binding with conventional band iron, and since each adjacent ream 3 is continuously secured, there is no need to use a top plate between the reams. The unity of the two can be made sufficiently strong.

Furthermore, since the stretch film 6 is wrapped around the lower part of the ream 3, it is possible to prevent the ream from slipping during transportation.

<<Effects of the Invention>> As detailed above, if the flat packaging method of the present invention is used, the reams and the pallet table and the cohesion between the reams, the protection and preservation of the flat packaging, and the economy and workability of packing can be improved. can be improved.

Furthermore, even if the pallet stand is dirty, the same effect can be obtained by using this paper on the pallet stand.

《Example》 Double-sided adhesive tape with a width of 25 mm (manufactured by Soken Kako Co., Ltd.) and the width
After binding the reams as shown in Figure 1 using 50mm kraft adhesive tape (Neo kraft tape: product name manufactured by Soken Kako Co., Ltd.), add a width to the lower part of the ream.
A 500 mm stretch film was wound in three layers while being stretched to 250-300%.

A rocking test was performed by shaking the ream packed as above 500 times (swinging angle: 6°, rotation speed: 40 times/
As a result, it was confirmed that the initial attitude was maintained with almost no cargo collapse.

In addition, the above double-sided adhesive tape is suitable for horizontal ground angles.
It was confirmed that it had a slip resistance of 25° to 45°. Incidentally, in actual transportation work, it is impossible for the horizontal ground angle to be greater than 25°.
