Description

Flat metal pallet {Flat metal pallet}

The present invention relates to a flat iron pallet, specifically, to increase durability and stability and to use safely and to expect productivity improvement.

Flat pallets are the most widely used for transporting goods. Wood pallets, which are easy to obtain and manufacture materials, have been the mainstream, but are highly susceptible to deformation and damage due to weakened strength. As problems such as such as to emerge, the synthetic resin pallets and steel pallets are mainly used.

However, the synthetic resin pallet is very weak to temperature changes, so it is not suitable for low temperature warehouses, and in case of fire, toxic gas is generated as well as flammable, causing a larger fire.

In addition, Japanese Utility Model Registration No. 3093964 is a representative example of the steel pallet. Looking at the structure, the face plate formed by alternating recesses and convex portions is formed integrally with one side to have an open hole, and the corresponding surface of the open hole. The support member is provided with a coupling groove formed on the upper and lower sides, and two face plates corresponding to each other in parallel by the coupling groove are coupled to the support member to be combined and joined by welding.

Therefore, the steel pallet of this structure brings productivity decrease when welding the whole contact surface when joining the supporting member between two face plates by welding, and there is a gap in partial welding. As the force to withstand is weakened, durability and stability are inferior, and the structure of the support member is also complicated, which causes a decrease in productivity, and both ends of each face plate are sharply exposed so that it may be damaged when contacted with the handler or other materials. Problems such as being pointed out.

Accordingly, an object of the present invention is to provide a steel pallet that can be used safely and excellent in durability and stability, and can be expected to improve productivity while being composed of steel resistant to heat change in order to solve the problems as described above.

In order to achieve the above object, the present invention forms a support member by bending the protective part on both sides of the upper surface plate in which the recessed portion and the iron portion are repeatedly formed, and bending the face plate in which the recessed portion and the iron portion are repeatedly formed like the upper surface plate in a rectangular shape. The upper and lower plates of the support member is characterized in that it is configured by bonding several reinforcing members.

Figure 1 is a perspective view of the present invention, the present invention is a cross-sectional metal upper surface plate 6 formed alternately in the cross-sectional recessed portion 2 and the convex portion 4, the cross-sectional recessed portion 8 and the convex portion 10 It is composed of a metal support member (12) formed alternately and bent in a rectangular shape on the side, and a metal reinforcing member (14) is sandwiched and fixed between the upper and lower plates of the support member (12).

In the above, the upper face plate 6 is formed to be longer than the width of the pallet A to be obtained, and both ends thereof are bent at the same time as crimping or bent after being crimped to form protective parts 16 and 18 which are bent in an L shape. To be.

Figure 2 is a perspective view of the support member used in the present invention, the support member 12 is to be bent inwards four places in the longitudinal direction to form a frame shape of the side rectangle, in bending the four places the upper face plate ( Through the compression of the corresponding parts, such as the protection parts 16 and 18 of 6), they may be bent at a right angle or through a punching hole to remove a portion of the portion corresponding to the bend line 20 before forming the recessed and convex parts. It is also possible to bend easily by forming (22).

That is, a roll forming machine is generally used in the upper plate 6 and the supporting member 12 to have the recesses 2, 8, and convex portions 4, 10 used in the present invention. If a part of the portion corresponding to the bending line 20 before the molding of (12) is removed by a punching machine to form the through hole 22, the recessed part 8 and the convex part 10 are formed by the remaining part when forming using the roll forming machine. While constructing) will have a through hole 22 in the corresponding portion.

However, in forming the through hole 22 in the portion corresponding to the bend line 20, as shown in FIG. 3, the side portion 24 between the recessed portion 8 and the convex portion 10 is almost as close to the end point of the convex portion 10 as possible. It is preferable to form in a substantially hexagonal shape which is connected at the right angle and reached the end point of the side part 24 by the parallel line which crosses the recessed part 8.

As described above, in the case of forming the through-hole 22 having a hexagonal shape in the portion other than the convex portion 10 of the bend line 20, the through-hole 22 is formed on the side surface as shown in FIG. Since it forms a "s" form perpendicular to the bottom of the) is bent without a separate pressing process or extra effort by simply applying a little force, the bending line 20 is exactly bent.

After bending using the through-holes 22, as shown in FIG. Therefore, it constitutes a rectangular frame on the side.

On the other hand, the reinforcing member 14 sandwiched between the upper and lower plates of the support member 12 does not need to specify its cross-sectional shape, but is preferably formed in a "c" shape or a "ㅁ" shape for strength reinforcement. .

In addition, when arranged between the upper and lower plates of the support member 12 may be arranged in the transverse direction, which is the longitudinal direction of the support member 12 as shown in Figure 5, the longitudinal direction of the support member 12 as shown in FIG. It can also be arranged in a longitudinal direction perpendicular to the.

However, when the reinforcing member 14 'is to be disposed in the longitudinal direction perpendicular to the support member 12, it is preferable to form the coupling grooves 26 and 28 of the width and depth to which the unevenness is coupled to the upper and lower ends.

In constructing the present invention, the support member 12 is bent using a through-hole 22 after molding using a punching machine and a roll forming machine, but several reinforcing members 14 are disposed at predetermined positions between the upper and lower plates before bending completely. After joining, the support member 12 is configured to have a sense of unity by welding or bolting, riveting, etc. with the reinforcing member 14 in a state of being completely bent in a generally rectangular shape on the side.

After fabrication of the support member 12, a plurality of side by side arrangements are formed, and a plurality of upper face plates 6 are arranged in a lattice shape on the upper surface thereof, and then each contact point is also welded, bolted, riveted, or the like. It is configured to have.

At this time, the protective parts 16 and 18, which are bent at both ends of the upper face plate 6, are in intimate contact with the side portions of the support member 12, so that they can be more strongly bonded and have smooth ends, thereby ensuring safety during handling. I can do it.

In addition, when the support member 2 is folded by using the through-hole 22 formed in the four bent lines 20, each surface is in contact with the surface constituting the through-hole 22. Since it maintains a right angle, the rectangular shape can be maintained even without welding the contact surface, and both sides of the reinforcing member 14 exert a bearing force as a leg together with the reinforcing member 14 to reinforce the force to withstand the load. The configuration can be simplified, resulting in increased durability, stability and productivity.

In addition, in the configuration of the present invention, as shown in Figure 7, the lower surface plate 6 'of the same shape as the upper surface plate on the bottom surface of the support member 12 may be used in a lattice configuration, which is weighted However, the strength is further reinforced and can be used on both sides.

Thus, in the present invention, when the support member 12 is bent, a plurality of reinforcing members 14 are interposed between the upper and lower plates to form a joint, and then the upper surface plate having the protective parts 16 and 18 on the upper surfaces of the plurality of support members 12. (6) by joining, so that the safety is ensured by the protective part (16) (18), and when the support member 12 is configured, both side portions thereof perform the function as a leg together with the reinforcing member (14) Durability and stability are improved by increasing the force to withstand the load, and the support member 12 is simply folded through the through-hole 22 after molding using a punching machine and a roll forming machine, and both sides of the support member 12 In addition, the reinforcing member 14, which serves as a leg, is a useful invention that can simplify the configuration and expect productivity improvement.
