For the sake of convenience, the thicknesses and dimensions of the structures shown in the drawings may be exaggerated, and they do not mean that the dimensions and the proportions of the structures should be actually set.

1 to 5, a wheel transporting tray according to an embodiment will be described. FIG. 1 is a perspective view showing a wheel transporting tray according to an embodiment of the present invention, and FIGS. 2 and 3 are a perspective view and a bottom perspective view, respectively, showing a cutaway portion of the wheel transporting tray shown in FIG. 4 is a schematic view for explaining the comparison between the first wheel rest part and the second wheel rest part, FIG. 5 is a schematic view for explaining conditions for forming the second step part and the third step part forming the first wheel rest part, 6 is a schematic view for explaining a formation position of a second cut portion according to an embodiment.

The wheel transport tray according to an embodiment of the present invention is used as a fixing member for carrying a plurality of automobile wheels W. The wheel W is stacked such that its side faces are directed upward and downward, and for convenience of explanation, this side face is defined as a laminated face W1.

The wheel transporting tray according to the present embodiment includes a tray body 105 formed in a plate shape. The tray body 105 is preferably formed in a rectangular plate shape for easy storage and transportation. However, if necessary, it may be formed in various shapes without being limited to a rectangular shape.

A plurality of first incisions 110 are formed in the tray body 105. The first incision part 110 is formed in a vertically penetrating shape by cutting an unnecessary part that does not contact the seating surface W1 of the wheel. The first incision 110 may be formed in a circular or polygonal shape with a smaller area than the laminated surface.

As shown in FIGS. 1 and 2, a first wheel receiving portion 115 is formed around the first cutout portion 110, and the first wheel receiving portion 115 is formed with a plurality of First step portions 120 are formed. The first stepped portions 120 are provided around the first wheeled seat portion 115 to discontinuously partition the boundary of the first wheeled seat portion 115. The first stepped portions 120 may be formed by a press vacuum forming method. That is, it can be formed in such a manner that the metal is pressed on one side and vacuum is adsorbed on the other side. However, if the first step 120 is continuously formed to form one circle in this process, the first wheel receiving part 115 may not be formed flat.

As shown in FIG. 3, a plurality of second stepped portions 130 protruding from the other side of the tray body 105 are formed. The second stepped portion 130 is formed to protrude in a direction opposite to the first stepped portion 120 described above to discontinuously form the boundary of the second wheeled portion 115a.

When one of the laminated surfaces of the wheel is seated on the first wheel seating portion 115, the laminated surface on the other side is stacked in such a manner that it is seated on the second wheel seating portion 115a of another wheel carrying tray.

4, the maximum distance between the diameters L2 of the boundaries of the second wheel rests 115a, that is, the second step 130 and / or the third step 1401, which face each other, Is larger than the diameter (L1) of the border of the one-wheel seating portion (115). In other words, the second step 130 is formed further from the center of the first cut 110 than the first step 120. This makes it easier to stack the wheels in the process of unloading a plurality of wheels. Specifically, when the first wheel transporting tray is covered on top of the wheels of the first layer after the wheels of the first layer are stacked on the first wheel transporting tray, the first step and the wheels of the first wheel transporting tray The angles and positions of the upper portions of the wheels may not be constant depending on the bending of the bottom surface on which the first wheel transporting tray is mounted or the mounted state of the wheel. In this case, It is unnecessary to align the wheels on the seat. Accordingly, it is preferable that the wheel seating portion of the surface covering the wheels of one layer is formed to have a larger clearance so that the laminated structure can be easily formed.

The second step 130 is preferably formed primarily between the edge of the tray body 105 and the first cutout 110 and is formed along the circumference of the first cutout 110 for space efficiency And can be projected in an arcuate shape.

The tray body 105 may have a plurality of protrusions 140 protruding upward or downward. The protrusions 140a formed adjacent to the first incision 110 may also serve as the second step 130 described above.

That is, the protruding portion 140a adjacent to the first cutout portion 110 has a slant face 1401 (hereinafter referred to as a third step) adjacent to the first cutout portion, similar to the second stepped portion 130 described above, So that a discontinuous boundary of the portion 115a can be formed.

The projection 140a located between adjacent first incisions among the protrusions 140a adjacent to the first incision 110 may be formed in the vicinity of each of the second wheel seating portions 115a of adjacent first incisions It is also possible to form a discontinuous boundary. In other words, the third step parts 1401 forming the boundary of the first incision part 110 may be formed in a protruding shape connected to each other.

For example, the second step 130 or the third step 1401 may be formed so as to protrude from the opposite side from the first step. However, the first step 120, (In Fig. 5, it is assumed to be 130-b). However, in this case, the boundary of the second wheel rest part can not be formed. The second stepped portion 130 and the third stepped portions 1401 protruding to the other side of the first stepped portion 120 are spaced apart from each other by the maximum spacing angle A1 ) Should be formed within about 150 degrees (assuming 130-a and 130-c in FIG. 5). The second step portion 130 and the third step portion 1401 can not be fixed uniformly even if an external force is applied due to the spacing angle within about 150 degrees, It is possible to prevent the wheel from being stably released.

As shown in FIG. 6, the tray body may form a second cut in a region except for the first reinforcement R1 and the second reinforcement R2. The first reinforcing portion R1 and the second reinforcing portion R2 are portions to which strength is to be particularly strengthened by applying shear force or tensile force when various external forces act on the laminated wheels. This is important for the health of the wheel transport tray as the incision area including the first incision is increased.

The first reinforcing portion R1 is defined as a width W1 of 1 to 1.5 times the radius of the first incision portion having a direction connecting the center O of the first incisions. The second reinforcing portion R2 is defined as a region having a width corresponding to the width of the first reinforcing portions R1 at a position of the intersection of virtual lines connecting between the first reinforcing portions R1. As shown in FIG. 1, the second cutout portion 1405 may be formed in a region except for the first reinforcement portion R1 and the second reinforcement portion R2. The second cutout portion 1405 may include a first reinforcement portion R1, It is preferable to form the protrusion 140 on the region except the reinforcing portion R2.

The edge of the tray body 105 may have a rim 150 having a bending structure at least three times. Here, the bending structure means a bend in the direction of about 90 degrees. In the case of FIG. 2, the rim 150 forms a bending structure three times in the upward direction, the lateral direction, and the downward direction from the tray body 105. With this structure, it is possible not only to increase the strength in the teburi, but also to prevent damage to the wrapping paper that surrounds the outer periphery of the wheels and the tray for stacking during transportation.

7, a wheel laminating structure using a wheel transporting tray according to an embodiment and a related loading operation will be described. 7 is a perspective view showing a state in which a plurality of wheels are stacked using a wheel transporting tray according to an embodiment.

As described above, the wheel transport tray 100 is mounted with the first stepped portion 120 protruding upward and then the wheels W are mounted to form a first layer, and then another wheel transporting tray 100 Thereby forming a laminated structure. The wheel dummy is moved to the production line of the automobile factory through the transportation process, and then the worker removes the wheel W from the wheel transport tray 100 and puts it into the conveyor of the production line.
