Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing a load shift when stacking and transporting a plurality of plate-like works such as a glass plate and a stainless plate having a smooth surface and slippery.

[0002]

2. Description of the Related Art In the case of transporting a horizontally stacked sheet-like work having smooth and slippery surfaces such as a glass plate and a stainless plate by a carrier such as a trolley, a conveyor and a forklift, the start of the carrier is started. The stacked plate-like works are apt to cause a load shift or a load collapse due to vibrations during stop, transportation, or the like.

FIG. 2 is a block diagram of a conveyed product in which plate-like works are horizontally stacked. The transported object 10 is formed by horizontally stacking a plurality of plate-like works W such as glass plates and stainless plates.
Between the plate-like works W, for example, plant powder 4 such as saffura is sprayed to prevent the surface from being scratched.

The plant-based powder 4 has an effect as a cushioning material for the plate-like works W, but the particles are too fine to serve as a friction resistance member. When it is carried by a carrier such as a dolly, a conveyor, and a forklift, a load shift is likely to occur in the directions shown in FIG. 2 (for example, distances a and b).

In order to prevent such a load shift, a conventional method of fixing a plurality of plate-shaped works W by using a film or a string is adopted for the load shift prevention. FIG. 3 shows a block diagram of a transported object to which a conventional load shift prevention method (film) is applied, and FIG. 4 shows a configuration diagram of a transported object to which another conventional load shift prevention method (string) is applied.

In FIG. 3, the article to be conveyed 11 is constructed such that plate-like works W such as glass are stacked to form a package, and a film 12 is wound around and fixed to an end of the entire package and placed on a pallet 13 to be transported. To be done.

Further, in FIG. 4, the article to be conveyed 15 is constructed such that plate-like works W made of glass or the like are stacked to form a package, the entire package is fixed with a string 16 and placed on a pallet 13 to be transported.

As described above, according to the conventional load deviation preventing method, the goods to be conveyed are fixed and conveyed by a plurality of plate-like works W such as glass with a film or a string, so that the deviation of the loads can be prevented.

[0009]

In the conventional load deviation preventing method for winding and fixing a film, the film is stretched by a film winding machine and wound around the corner of the conveyed object while giving elasticity, so that the edge portion of the plate-like work is Due to the problem that the film is cut by, or the film is cut or peeled off, the cut edge of the film may wind around the roller of the conveyor and cause the load collapse.

Further, the cost of the film winding machine is high, the capital investment is high, and the cost of the film itself is high, so that the cost of transporting the plate-shaped work increases.

On the other hand, according to the conventional method for preventing load deviation, which is fixed by using a string, if the tightening method is weak, the load easily occurs during the transportation, and if the tightening method is too strong, the edge strength of the glass plate is weak during the transportation. There is a problem that the work piece is damaged.

The present invention has been made to solve the above problems, and its purpose is to simplify the work and equipment,
It is an object of the present invention to provide a method for preventing load deviation of a plate-shaped work which is excellent in economic efficiency and can reliably prevent load deviation.

[0013]

In order to solve the above-mentioned problems, a method of preventing load deviation of plate-like works according to the present invention spreads a frictional resistance body having elasticity between plate-like works when stacking the plate-like works. It is characterized by doing.

Further, the friction resistor used in the load deviation preventing method for a plate-like work according to the present invention is formed of a foamable resin powder.

[0015]

According to the load deviation preventing method for a plate-like work according to the present invention, since the frictional resistors having elasticity are scattered between the plate-like works, the glass plate is protected as a cushioning material and the slippery glass plate is protected. The load shift can be prevented.

Further, the load deviation prevention method for a plate-like work according to the present invention is simple and economical because the frictional resistance body is formed of a foaming resin powder such as sponge and is sprayed on a glass plate or the like. Can be realized.

[0017]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a configuration diagram of a conveyed product to which a method for preventing load deviation of a plate-like work according to the present invention is applied. In FIG. 1, when plate-like works W such as glass plates are stacked horizontally,
First, a predetermined amount of a frictional resistance body formed of a foamable resin powder 2 such as a sponge is evenly dispersed on a plate-like work W, and then a predetermined amount of a cushioning material formed by a safflower 4 is evenly dispersed. To do.

The plate-like works W are stacked on the plate-like works W on which the expandable resin powder 2 and the safflaw 4 are dispersed, and the expandable resin powder 2 and the safflaw 4 are again dispersed, and the plate-like works W are further dispersed. By stacking and repeating these steps, the conveyed product 1 normally composed of, for example, 100 to 200 plate-like works W is formed.

The expandable resin powder 2 is preferably a sponge mass having a diameter of 0.5 to 1.5 mm, which is larger than the diameter of the safflaw 4 (about 100 to 200 μm). Then, apply vibration to the plate-shaped work W and spray it onto the plate-like work W. In addition, the volume ratio of the sponge 2 and the saffraw 4 is preferably 10 to 20 with respect to the sponge 100.

Flat work W such as glass plates stacked flat
Receives the vertical gravity G and compresses the sponge 2 sandwiched between the plate-like works W, and the compressed sponge 2 exerts a constant pressure on the plate-like work W by the elasticity held by the sponge 2 itself. Press with.

The frictional resistance of the surface of the sponge 2 pressed against the plate-like work W with a constant pressure is carried by a carrier such as a carriage, a conveyor and a forklift when the carrier 1 is placed on the pallet 3. The load shift is prevented by setting the force so as to be larger than the force acting on the conveyed object 1 due to the start and stop of the conveyer or the vibration during the conveyance.

Further, the sponge 2 acts as a cushioning material together with the safflower 4, and prevents the scratches due to the friction between the plate-like works W such as glass plates and the damage due to the impact.

The sponge 2 has been widely used as a cushioning material or the like for many years in packaging and construction, is safe for humans, is easily available, and is a low-priced material. Further, since the sponge 2 used in the present invention is used in a finely pulverized shape, there is an advantage that a scrap of the sponge, which has no conventional utility value, can be effectively used.

Further, when the method of the present invention using a sponge is adopted, the sprinkler spraying machine can be constituted by a simple tool for dropping a fixed amount of sponge powder from the mesh, and the sponge powder is glassy by the action of static electricity. It has the advantage that it can be easily attached to a plate-like work W such as a plate and is hard to fall off.

Further, regarding the reuse of the sponge 2 and the safura 4, the difference in specific gravity between the sponge 2 and the safura 4 is used, and the mixture of the sponge 2 and the safura 4 is put into water, and the floating sponge 2 and the sedimenting safura 4 are separated. Can be collected.

As the friction resistance body, expanded polystyrene is suitable in addition to sponge.

[0026]

As described above, according to the load deviation preventing method for a plate-like work according to the present invention, a friction resistance body having elasticity is dispersed between the plate-like works to protect a glass plate or the like as a cushioning material. Since it is possible to prevent the slippage of the slippery glass plate, it is possible to provide a method for preventing the slippage of the plate-like work suitable for transportation.

Further, the load deviation prevention method for the plate-like work according to the present invention can prevent the load deviation of the plate-like work only by spraying the powder such as the sponge, so that it does not require any special equipment or device and is simple. Can be constructed economically.

Therefore, it is possible to provide a load deviation preventing method for a plate-like work which is simple in work and equipment, excellent in economical efficiency, and capable of surely preventing load deviation.
