Description

Pallet {Pallet}

The present invention relates to a pallet for easily moving a loaded object using a forklift, and to insert a strength reinforcing core material into a pallet made of a synthetic resin to endure a lot of weight while reducing the weight.

Existing pallets that are injection-molded using synthetic resins are usually made of a lower plate that reaches the bottom and an upper plate on which objects are placed. The upper plate and the lower plate are supported by a supporter, and the fork hole can be fitted in all directions. To form a, a plurality of holes are formed in the upper plate and the lower plate to reduce the weight.

These pallets are loaded on the top plate and then put the fork of the forklift in the fork hole to lift the pallet or carry it, and the bottom plate can always bear the load placed on the top plate because it can reach the flat bottom, but the pallet If a load is placed on both sides of the pallet under load, the pallet with considerable weight must be used to withstand the load on the pallet.

In other words, if the pallet is placed on both sides of the pallet while the goods are loaded, the load on the pallet's top plate is transferred to both sides of the pallet as it is, so long as the pallet does not use a large-capacity pallet that can withstand sufficient load There is a problem that can not load the goods, using a large amount of pallet can solve the problem of breaking the pallet, but there is a problem that is heavy and increased cost.

The present invention allows the pallet to withstand the load of the article even if it is placed on both sides of the bottom plate of the pallet in the state where the article is loaded in the pallet, and can withstand the load while reducing the weight.

The present invention inserts the core material having the shape of a rectangular square tube made of metal or a high strength synthetic resin at regular intervals on the upper plate of the synthetic resin plate, the core material is installed at regular intervals, but is preferably installed on both sides of the upper portion of the support .

The present invention is made by insert-injecting a strength reinforcing core material into the upper plate of the pallet at regular intervals, so that the core load is distributed and withstands the load applied to the upper plate.

That is, the present invention inserts the core material into the upper plate when injection molding the pallet, but the core material is to be installed on both sides of the upper support, the core material is suitable for the square tube shape, the material is superior in strength than the synthetic resin for injecting the pallet Use metal, aluminum, polycarbonate, or glass-containing nylon.

The present invention is able to withstand the load applied to the pallet when hanging both sides of the bottom of the pallet with the object placed on the pallet by inserting the core material into the top plate without increasing the weight of the pallet.

Therefore, it is possible to manufacture at low cost, and it can be manufactured simply by insert injection, and it is possible to manufacture pallets that can withstand a lot of loads without increasing the weight of the resin, especially when the two sides are placed on the pallet There is an advantage that it is easy to withstand the load.

The present invention is a pallet provided with a support plate constituting the upper plate and the lower plate and the upper plate and the lower plate formed by using a synthetic resin, the load when the both sides of the lower plate of the pallet by insert injection of a high strength core material at regular intervals on the upper plate To endure it.

The pallet 100 forms a fork hole 40 through which the upper plate 10 having the hole 11 and the lower plate 20 having the hole 21 is connected to the support 30 but penetrates back and forth or from side to side. By doing so, the fork of the forklift truck can be moved to the fork hole 40, and the pallet 100 is moved while loading an object.

When the pallet 100 is loaded on an object, the fork of the forklift is inserted into the fork hole 40 to lift the pallet 100 upwards, and the fork lifts the upper plate 10 lower portion of the pallet 100. When lifting the pallet 100 loaded with goods by a forklift, the pallet 100 may receive a sufficient load, and also when the bottom plate 20 of the pallet 100 is placed on the floor while touching the floor. Since the load applied to the upper plate 10 through the support 30 is evenly distributed, it is possible to withstand the load of the loaded object.

However, when the pallet 100 is to be placed on both sides of the lower plate 20 without placing the pallet 100 on the floor, the load applied to the pallet 100 is concentrated on both sides. Therefore, there is a problem such that the middle of the pallet 100 falls or breaks.

In order to solve this problem, one should use a large-capacity pallet that can withstand a lot of load. However, since the large-capacity pallet has a problem that a lot of weight and a manufacturing cost are increased, in the present invention, it is possible to withstand the load while reducing the weight. In order to insert the high-strength core 50 into the upper plate 10 of the pallet 100.

The present invention is to use a core 50 having a shape of a substantially rectangular tube, the core 50 is made of metal or aluminum or polycarbonate or glass-containing nylon, the square is the most suitable but necessary Therefore, it may be manufactured in a circle or polygon.

The core material 50 is to be produced by insert injection molding during the injection molding of the pallet 100, the core material 50 is produced in a form recessed in the upper plate 10, but the upper and lower parts are not exposed, the left and right sides are required Can be exposed accordingly.

Here, the core 50 is installed at a predetermined interval on the top plate 10, the insert position of the core 50 is suitable for both sides of the upper portion of the support 30, but may be installed to maintain an appropriate interval, and also the core 50 The upper and lower parts are to be recessed, but the left and right sides may be recessed or exposed. When the side of the core 50 is exposed, a separate stopper prevents the side of the core 50 from being exposed.

The core 50 of the present invention is not limited to the number of uses, but it is preferable to install a relatively equal distance apart, and to transfer the load of the object applied to the upper plate 10 to the lower plate 20 to the lower plate 20 Even if placed on both sides of the top plate 10 to withstand the load.

In the present invention, when the injection molding of the pallet 100, the core material 50 is placed in the mold in advance, and the injection is made so that the core material 50 can be injected into the upper plate 10 of the pallet 100, the pallet 100 Is to disperse the load of the object in the core 50 when placed on both sides of the lower plate 20 in the state loaded with the upper plate 10, the core 50 is in the form of a square tube Good, using metal or aluminum or polycarbonate or glass-containing nylon, but using a superior strength than the synthetic resin for producing the pallet (100).

Here, the core material 50 may be formed between the core material 50 and the pallet 100 during the cooling process when the insert is injected into the pallet 100, and this phenomenon may occur after the adhesive is applied to the outside of the core material 50. It can be solved by making the injection, if the adhesive is applied to the outside of the core material 50 does not occur the phenomenon that the pallet 100 and the core material 50 is separated.

And the core material 50 of the present invention can be inserted into the insert injection molding in the form recessed on the top plate 10 of the pallet 100 or the insert injection molding in the form that the side is exposed, if the core material 50 is exposed to the outside It is preferable to close the side surface of the core material 50 using a stopper.

When the core 50 is inserted into the upper plate 10, when the object is loaded on the upper plate 10, the load of the object is transferred from the support 30 to the lower plate 20 through the upper plate 10 and the core 50. When lifting the pallet 100 by inserting the fork of the forklift into the fork hole 40, the load of the object is received from the upper plate 10, and this state has a lower problem in enduring the load of the object in the pallet 100. none.

However, after lifting the pallet 100 loaded with the goods as described above, without placing the pallet 100 on a flat floor, only the bottom plate 20 of the pallet 100 is laid down so as to span the load of the object Since 10 is not tolerable, in the present invention, the core 50 is insert-injected so that the load of the object is distributed to the core 50 so that the load is distributed to the lower plate 20 through the support 30 to sufficiently distribute the load. Make it work.

At this time, the core material 50 is installed in a direction supporting both sides of the lower plate 20 so that the core material 50 eventually forms a shape that crosses the upper part of the pedestal supporting both sides of the lower plate 20 so that the load of the object is the core material 50. Is distributed through).

Therefore, the core material 50 is to be in the form that spans the pedestal supporting both sides of the lower plate 20 of the pallet 100, but the core material 50 is effectively applied to the upper plate 10 by being installed on both sides of the upper portion of the support (30) The load of the article to be delivered to the core 50, and the load transmitted to the core 50 is distributed through the support 30 to be delivered to the lower plate 20 to withstand the load of the article.

That is, the load applied to the object by using the core material 50 is transmitted to both sides of the pallet 100, and the load transmitted to both sides of the pallet 100 is a pedestal that both sides of the lower plate 20 of the pallet 100 is spread over. Since it is distributed through, the pallet 100 can withstand the load of the object.

Therefore, without using a large amount of pallets, it can be stored in a state where the load on both sides of the lower plate, and a small capacity of pallets can be used to reduce the production cost and reduce the weight.
