Description

[Detailed Description of the Invention] This invention relates to a pallet on which a large number of elongated materials such as aluminum extruded sections are stacked.

Conventionally, as a pallet used for transporting, storing, etc., e.g. long aluminum sections, a rectangular pallet main body a has parapet-shaped side frames b protruding from opposing long sides as shown in Fig. 7. A palette of structures A is known. This conventional palette A
In use, on the main body a of the pallet, a large number of long shapes m are arranged parallel to each other in each step parallel to the longitudinal direction of the pallet main body, and spacers s are sandwiched between each step. They are stacked in stages for transportation or storage, but in order to unload the entire long shape from the pallet, lifters L and L installed on the outside of both longitudinal ends of the pallet are used to lift both ends of the entire long shape. After lifting the entire long shape material m to a higher position than the side frames b and b of the pallet and moving the empty pallet in this state, the lifter device is lowered to move the entire long shape material onto the conveyor. However, since the lifter devices L and L have to be installed outside both ends of the pallet A in the longitudinal direction, the length of the elongated material m to reach both lifter devices L and L must be In cases where the elongated material does not hold up well or is easily bent, mechanical loading and unloading operations using the lifter device described above have become difficult.

The present invention provides a pallet that can mechanically unload loaded long materials using a certain device even when the loaded long materials are short or easily bent. Board 10
, a plurality of pairs of posts 6 that engage and support support plates 10 vertically provided on both sides of the pallet body 2 so as to be able to rise and fall; and the support plates 10 of the pallet body 2.
It consists of an opening 12 provided in a portion corresponding to. Embodiments of the present invention will be described below with reference to the drawings.

In Figures 1, 2 and 3, main body 2 of pallet 1
This is a rectangular frame consisting of long vertical frame members 3, 3 and short horizontal frame members 4, 4, in which horizontal bars 5 are connected at appropriate intervals. Two pairs of posts 6, 6, 6', 6' facing each other are fixed vertically to the pallet main body 2 at positions offset from the horizontal bars 5 on each outer surface of the pallet body 2. It has been done. The above-mentioned two pairs of posts 6, 6, 6', 6' are made by fixing the bottom surface of a bowl-shaped cup 7 having a flange 8 on the mouth edge as shown in the fourth figure to the lower end of a square prism body. In the example, as shown in the first figure, the upper end of the post is placed on the upper surface of the pallet body 2 at both positions corresponding to the middle of the first and second horizontal bars 5, 5 from both ends of the pallet body 2 in the longitudinal direction. The lower ends of the cups 7 are respectively fixed to angle fittings 9, 9, which are protruded from the outer surfaces of the vertical frames 3, 3, with the cups 7 protruding toward the lower surface of the pallet body 2, respectively. . In this case, the posts 6, 6, 6', 6' are fixed with a small distance d between them, and the cups 7... teeth,
The inner diameter is such that it can be fitted into and removed from the upper ends of the posts 6, 6', and the flanges 8 are formed to have a diameter that extends below the vertical frame members 3, 3 of the pallet body 2 when viewed from above.

The support plates 10, 10' to be respectively supported by the pairs of posts 6, 6, 6', 6' have U-shaped engagement grooves at both ends of the substantially rectangular plates corresponding to the pairs of posts. 11, 11, 11', 11' are provided, and these support plates 10, 10' connect the engagement grooves 11, 11, 11', 11' to the posts 6, 6, 6', 6 forming a pair. The space between the horizontal bars 5, 5 opens into openings 12, 12' below the support plates 10, 10', through which the pallet body 2 opens. located as.
13... are height adjustment spacers added to the upper surfaces of the horizontal frame members 4, 4 and the horizontal bars 5....

An example of how the above palette 1 is used will now be described. In Figures 5 and 6, on the main body 2 of the pallet 1, a large number of long aluminum sections m... are arranged parallel to each other in each step parallel to the longitudinal direction of the pallet main body, and each step is made from a plurality of square rods. spacer s
Stack this palette 1 in multiple layers with ... in between.
, the post 6 is attached to the two roller conveyors 14, 14...
Cup 7... is placed thereon and moved to the section loading/unloading position P. At the loading and unloading position P, lifter devices 15 and 15' are respectively provided below corresponding to the pallet support plates 10 and 10'.
As shown in Figure 6, it consists of a hydraulic cylinder 17 installed vertically in a pit 16 and a lift plate 19 fixed to the tip of its ram 18, and three C-shaped claws 20... are installed on one side of the loading/unloading position P. The roller conveyor 14 is provided with four belt conveyors 21 on the other side of the loading/unloading position P. 14 and at positions shifted from the advancing and retreating directions of the C claws 20.

When pallet 1 is stopped at the unloading position,
When the lift plates 19, 19 are raised by the drive of the hydraulic cylinders 17, 17 of both lifters, the lift plates push up the support plates 10, 10' through the openings 12, 12' of the pallet body 2, thereby lifting the long Shape m...The whole is lifted to an appropriate height from the upper surface of the pallet body 2. In this case, even sections shorter than the pallet 1 are pushed up by the support plates 10, 10'. Next, move the C claw 20 forward and insert its claw between the entire shape and the pallet body 2,
Next, the C claws 20 are raised to lift up the entire profile, then advanced to the side of the belt conveyor 21, and then lowered to lower the entire profile m onto the belt conveyor 21.

Incidentally, if the shape material lifted by the support plates 10, 10' is bent, the number of logarithms of posts and the number of support plates may be increased as appropriate. In addition, in the above embodiment, the pallet main body 2 includes vertical frame members 3, horizontal frame members 4, and horizontal bars 5.
Although the structure is not limited to this, for example, a plate-like structure may be used.

In addition to the above-mentioned example, the above-mentioned lifter device can also be of a type in which the pallet 1 is lowered while the support plates 10, 10' on which the entire elongated shapes m are placed are held at a constant height.

In addition, in the case of the pallet of the above embodiment, the empty pallet 1... is moved to the post 6, as shown in the second figure.
While appropriately shifting the positions of 6, 6', and 6' from the post positions of other pallets when viewed from the side, place the cup flanges 8 of the upper pallet on the vertical frame members 3, 3 of the lower pallet and stack them one by one. be able to. In this case, the pallet posts 6, 6, 6',
Since there is a small distance d between the vertical frame members 6' and the outer surfaces of the vertical frame members 3, 3, stacking becomes easy. Moreover, a pallet 1 loaded with a large number of elongated shapes m can be stacked one after another by fitting the cups 7 of the posts of the upper pallet onto the tips of the posts of the lower pallet, as shown in the third diagram. can. Stacking as described above saves space for transporting and storing pallets or profiles.

According to the pallet for loading long materials of this invention, even if the loaded long materials are short or easily bent, the long materials can be unloaded by pushing up multiple support plates through the openings in the pallet body using an appropriate lifter device. In addition, when loading and unloading materials, since the support plate is interposed, a sufficient gap can be created between the pallet body and the long materials regardless of the length of the materials, and the accuracy is not too high. Using C-shaped claws, etc., materials can be loaded and unloaded to the required location without damaging them, and each support plate is held by a pair of posts so that they are always in the same position, making it possible to quickly load long materials onto pallets. In addition to being easy to load and unload long materials, if a lifter device is installed at a position corresponding to multiple support plates, it will be easier to load the pallets onto the lifter device. In order to prevent rubbing between the long timber and the post, the long timber is usually stacked with a space between the posts, but even if the long timber collapses due to this, if the long timber is between the paired posts. Lift up with a lifter,
This makes it possible to mechanize the loading and unloading of long materials, and since the support plate is engaged with the post, there is no risk of it being lost during storage or transportation of empty pallets. There is no such thing.
