Description

The present invention relates to a transportation pallet that can be stacked (stacked) in a nested manner and can stack two-stage objects to be loaded.

Stackable transport pallets are known, for example, as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2001-240056) and Patent Document 2 (Japanese Utility Model Laid-Open No. 1-61036). The transportation pallet has four pillar members erected at the four corners of a rectangular lower waist member, and the upper ends of each pillar member are horizontally connected in a U-shape in plan view with three connecting members. . When stacking pallets, the pallets are stacked from the front side without a connecting member.

JP 2001-240056 A Japanese Utility Model Publication No. 1-61036

Since this type of conventional transportation pallet has a configuration in which the front side connecting member that obstructs stacking is omitted, the object to be transported is stably mounted on the three connecting members that are U-shaped in plan view. This is impossible, and the place where the object to be transported can be mounted is limited to the lower waist member. For this reason, there is only a method of stacking transportation pallets in two stages as shown in FIG. 3 of Patent Document 1 (Japanese Patent Application Laid-Open No. 2001-240056) in order to further load an object to be transported on the transportation pallet. There was a problem in terms of use efficiency of the pallet for transportation.

SUMMARY OF THE INVENTION An object of the present invention is to provide a transportation pallet that can be stacked and can be stacked in two stages.

In order to solve the above-described problems, the present invention provides a rectangular lower waist member on which an article to be transported can be mounted, four column members erected at four corners of the lower waist member, and the four column members. The front and rear left and right connecting members that connect the upper end portion of the front and rear sides in a rectangular shape in the horizontal direction, and the front connecting member of the four connecting members is movably disposed toward the rear connecting member. And at least two of the four connecting members facing each other are formed with support portions capable of supporting a transported object different from the transported object mounted on the lower waist member, When stacking objects in two stages, the front side connecting member is moved to the front side to connect the upper ends of the two front side column members to each other, and when storing, the front side connecting member is used as the rear side connecting member. A pallet for transportation characterized in that it can be stacked in a nested manner in a moved state.

Since the present invention has four connecting members on the front, rear, left and right connecting the upper ends of the four pillar members, the transported object can be stably mounted using these four connecting members. It is possible to stack the objects to be transported on one transport pallet including the objects to be transported mounted on the lower member. Further, by moving the front connection member to the rear connection member, nested stacking (stacking) is also possible as in the prior art.

1A and 1B are perspective views of a transportation pallet 100 according to an embodiment of the present invention. For convenience of the following description, the lower left of the transportation pallet 100 in FIG. 1A is the front side, the lower right is the right side, the upper left is the left side, and the upper right is the rear side.

As shown in FIG. 1 (a), the transportation pallet has a square lower back member 10. The shape of the lower waist member 10 is not limited to a square, but may be a rectangular shape or may be a rectangle. As a design example of the lower back member 10, for example, a 11-inch pallet (1100 mm × 1100 mm × 150 mm) can be a square with a side of 1150 mm so that the lower back member 10 can be mounted. The transported object W is placed on the 11-type pallet as shown in FIG.

The lower waist member 10 is a combination of a plurality of parallel beams 10a to 10d with a predetermined interval, and is disposed on the inside with two relatively narrow beams 10a and 10b on both the left and right sides. Two girder members 10c and 10d having a relatively wide width are provided. The four girder members 10a to 10d form a square mounting surface for the transported object W. Note that the use of the girders 10a to 10d is mainly for weight reduction, but it is also possible to use a single-plate lower back member without using the girders 10a to 10d.

The two girder members 10a and 10b on the left and right sides are flat square pipes arranged vertically. Further, the two inner girders 10c and 10d constitute the main support surface of the article W to be transported, and are wide square pipes arranged horizontally. Fork pockets for cargo handling are formed inside the girders 10c and 10d, and a fork 90 of a forklift can be inserted horizontally from the ends of the girders 10c and 10d. The front end side and the rear end side of the four girders 10a to 10d are welded and connected by short square pipes 10e and 10f, respectively, to form an integrated lower waist member 10. In addition, by forming fork pockets in the girders 10c and 10d themselves that are the support surfaces of the article to be transported W, it is possible to reduce the overall height of the transport pallet 100 and to make it compact.

Equal-length column members 20 a to 20 d are erected vertically at four corners of the lower waist member 10. As a design example of these column members 20a to 20d, the height can be set to 1120 mm. The front column members 20a and 20b are each formed by welding two square pipes in parallel, and have a higher strength than the rear column members 20c and 20d. This is because the reinforcing members 30 are disposed between the rear column members 20c and 20d, as will be described later, while the transported object W is placed between the front column members 20a and 20b. It is because it is open to.

The lower ends of the front pillar members 20a and 20b are located at the joints between the outer beams 10a and 10b of the lower waist member 10 and the square pipe 10e. ) Is welded through. Therefore, the front column members 20 a and 20 b are located on the outer side in the left-right direction of the rectangular outer edge of the lower waist member 10. The reason for welding through the “about 3 mm thick steel plate” is to secure a clearance between the column members 20 a and 20 b during stacking.

The rear column members 20c and 20d are formed of square pipes, and the lower ends of the column members 20c and 20d are located at the joints between the beam members 10a and 10b of the lower waist member 10 and the square pipe 10f. 10b is welded to the rear end. Therefore, the rear column members 20 c and 20 d are located on the rear side of the rectangular outer edge of the lower waist member 10. The upper ends of the rear column members 20c and 20d are interconnected by a horizontal rear connection member 40.

The rear side connecting member 40 is formed of a square pipe, and both left and right end portions of the rear side connecting member 40 are welded to the inner side surfaces of the upper end portions of the column members 20c and 20d. The upper surface 40a of the rear side connecting member 40 is horizontal, and a regulating piece 40b using a steel bar is welded to the outer edge of the rear side connecting member 40 in the vicinity of both ends of the upper surface 40a. A similar regulating piece 60b is also welded to the upper surface 60a of the front connecting member 60, as will be described later with reference to FIG. The shapes of the restricting pieces 40b and 60b do not have to be rod-like, and may be any shape that can abut both front and rear ends of the base plate portion Wa as will be described later.

By the upper surface 40a and the upper surface 60a inside the regulating pieces 40b, 60b, the front and rear ends of the rectangular plate-like base plate portion Wa disposed at the bottom of the transported object W are configured to be supportable. That is, the upper surface 40a and the upper surface 60a constitute a support portion for the transported object W. As the base plate portion Wa, for example, a resin 11-type pallet (1100 mm × 1100 mm × 150 mm) can be used.

The mutual interval between the restricting pieces 40b and 60b is set to 1100 mm + α at the maximum when matching the dimensions of the 11-inch pallet. + Α is a play that allows for dimensional errors. If + α is too large, it will cause looseness of the transported object W, but conversely if it is too small, the base plate portion Wa cannot be removed smoothly, so it should be within an appropriate tolerance range.

The transported object W is placed on such a base plate part Wa. The transported object W needs to be within a range of 1100 mm × 1100 mm so as not to protrude from the end of the base plate portion Wa, but the top surface of the transported object W does not need to be particularly flat.

An inclined reinforcing member 30 connects the lower surface of one end of the rear connecting member 40 and the inner surface of the lower end of one of the rear column members 20c and 20d (here, the rear column member 20c). With this reinforcing member 30, it is possible to increase the load resistance of the transport pallet 100 when the transported object W is stacked in two stages.

The reinforcing member 30 is formed of a square pipe, and the position of the front side surface (left side surface in FIG. 5) of the reinforcing member 30 coincides with the position of the rectangular outer edge of the lower waist member 10 as shown in FIG. 5. Therefore, the rear end side of the article to be transported W mounted on the lower waist member 10 can be brought into contact with the reinforcing member 30 at the rear end of the lower waist member 10. Positioning is possible.

Further, the upper ends of the right and left column members 20a and 20c and the upper ends of the left and right column members 20b and 20d are connected by horizontal side connecting members 50 and 50, respectively. The side connecting members 50 and 50 are flat rectangular pipes arranged vertically, and the inner surfaces of the rear end portions of the side connecting members 50 and 50 are approximately connected to the outer surfaces of the upper end portions of the rear column members 20c and 20d. It is welded via a 3 mm thick steel plate (not shown). The reason why welding is performed through the “about 3 mm thick steel plate” is to secure a clearance between the side connecting members 50 and 50 during stacking.

The upper edges of the side connecting members 50 and 50 are arranged to be slightly higher than the upper surface 40a of the rear connecting member 40 and the upper surface 60a of the front connecting member 60 described later. Moreover, the front end part lower part of the side connection members 50 and 50 is welded to the upper end part of the front side column members 20a and 20b. Accordingly, the side connecting members 50, 50 are located on the outer side in the left-right direction of the rectangular outer edge of the lower waist member 10.

The upper ends of the front left and right column members 20a and 20b can be interconnected by a detachable front connecting member 60. For the mutual connection, engagement pieces 60c having a U-shaped cross-section opening downward are fixed to both ends of the front side connection member 60. The engaging pieces 60c are slidably engaged with the upper edges of the side connecting members 50, 50, and moved to the front end side along the side connecting members 50, 50, whereby the front pillar members 10a, 10b are moved. Are connected to each other.

As shown in FIG. 3, L-shaped stoppers 50 a that extend short toward the rear ends of the side connection members 50, 50 are fixed to the front end portions of the left and right side connection members 50, 50. Then, by receiving the end portions of the engaging pieces 60c at both ends of the front side connecting member 60 from the front-rear direction in the gap formed between the stopper 50a and the upper edges of the side connecting members 50, 50, the front side The connecting member 60 is positioned.

Similar to the rear connection member 40, the front connection member 60 is formed of a square pipe and has a horizontal upper surface 60a. And the restriction piece 60b using a steel bar is brought close to the outer edge of the front side connecting member 60 and welded to both ends of the upper surface 40a as shown in FIG. The height of the upper surface 60 a of the front connection member 60 is the same as the height of the upper surface 40 a of the rear connection member 40.

Therefore, as shown in FIG. 4, the transported object W can be mounted between the rear connecting member 40 and the front connecting member 60, and both front and rear end portions of the base plate portion Wa of the transported object W are The front and rear connecting members 60 and 40 are supported by the upper surfaces 60a and 40a, and the movement of the base plate portion Wa in the front-rear direction is restricted by the restricting pieces 40b and 60b. The left and right side portions of the base plate portion Wa of the article to be transported W are regulated by the inner side surfaces of the side connecting members 50 and 50.

(Modified embodiment)
FIG. 6 shows a transportation pallet 100 according to a modified embodiment of the present invention. In this modified embodiment, a protruding portion 50b extending horizontally in the front-rear direction is welded to the inner side surface of the side connecting member 50, and both left and right side portions of the base plate portion Wa of the article W to be transported on the upper surface of the protruding portion 50b. Can be supported.

Thereby, the base plate part Wa of the article to be transported W can be supported on the upper surface of the overhanging part 50b together with the upper surfaces 40a and 60a of the connecting members 40 and 60 described above, and the support stability of the object to be transported W can be improved. Can be increased. In this case, the upper surface of the overhang 50b also serves as a support for the transported object W.

It is also possible to support the transported object W only by the overhang portions 50b and 50b of the side connecting members 50 and 50 without supporting the transported object W by the front and rear connecting members 40 and 60. In this case, the front and rear connecting members 40 and 60 can be made narrower and lighter.

The transport pallet 100 is configured as described above, and the transported object W is mounted on the lower waist member 10 in a state where the front side connecting member 60 is attached and configured in a cubic frame shape as shown in FIG. In addition, another transported object W can be mounted between the front side connecting member 60 and the rear side connecting member 40. In this way, the transport pallet 100 can mount the transported object W in two stages, upper and lower, and the amount of the transported object W can be doubled compared to the conventional one, and the use efficiency of the transport pallet 100 is increased. can do. In addition, the base plate part Wa of the bottom part of the to-be-transported object W is not necessarily required. If the transported object W itself has a required shape and rigidity, the base plate portion Wa may be omitted.

Further, the transport pallet 100 can also be stacked as shown in FIG. 2B, thereby facilitating storage in a space-saving manner or transport by truck or the like. When stacking, the front connecting member 60 is moved to the rear connecting member 40 as shown in FIG. Then, the transport pallet 100 to be stacked is stacked from the front side of the lower transport pallet 100 as shown in FIG. 2B using a forklift. In this stacking state, the reinforcing members 30 of the transportation pallet 100 are positioned in the front-rear direction, so that the reinforcing members 30 do not interfere with stacking.

On the other hand, if the reinforcing member 30 is disposed between the side connecting members 50 and 50 and the lower beams 10a and 10b, the reinforcing member 30 interferes with the front pillar members 20a and 20b, so that stacking is impossible. Become. For this reason, the reinforcing member 30 is not disposed between the side connecting members 50 and 50 and the lower beams 10a and 10b.

(Another modified embodiment)
Next, a transportation pallet 100 according to another modified embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 7A to 7C, the transport pallet 100 is configured such that a rectangular frame member 70 is fitted on an upper portion thereof, and a transported object W can be mounted on the frame member 70.

The frame member 70 is formed by connecting half frames 71 and 72 having reinforcing bars 71a and 72a in the middle of a rectangular frame to each other by a pair of hinge portions 73 and 73 using hinges. It is possible to fold the mountain. The rear side portion 70a of the frame member 70 is connected to the rear connection member 40 by a pair of hinge portions 74 and 74 as shown in FIG. 7A. The front other side portion 70b of the frame member 70 is obtained by integrating the above-described front connection member 60.

Then, the frame member 70 is bent at the hinge portions 73 and 73 as shown in FIGS. 8A to 8C, so that the front other side portion 70 b (front connection member 60) is the upper edge of the left and right connection members 50 and 50. It is possible to move in the left-right direction. In addition, you may attach the control pieces 40b and 60b shown in FIG. 3 on the upper surface of the back side one side part 70a and the front side other side part 70b in order to prevent the position shift of the to-be-transported object W. FIG.

When stacking the transport pallet 100, the frame member 70 is folded toward the rear connecting member 40 as shown in FIGS. 7C and 8C, and is folded using a forklift as shown in FIGS. 9A and 9B. Thus, the upper transportation pallet 100 is stacked obliquely forward from the lower transportation pallet 100. In the stacking state, the frame member 70 folded vertically to the rear side overlaps in the front-rear direction as shown in FIG.

As mentioned above, although embodiment of this invention was described, this invention can be variously deformed without being limited to the said embodiment. For example, in the above embodiment, the transportation pallet 100 is mainly composed of a square pipe, but it is needless to say that the transportation pallet 100 can use various materials other than the square pipe. In the embodiment of FIG. 1, the front connection member 60 is configured to be detachable. However, the front connection member 60 may be configured to be slidable along the left and right connection members 50, 50. Further, although only one reinforcing member 30 is disposed obliquely, an additional reinforcing member may be disposed in a cross shape with a reverse inclination.
