Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a long object is held on a pallet, transported and accumulated together with the pallet at a predetermined location, and then
This invention relates to a method of transferring this long object together with a pallet to a pedestal and erecting it upwardly away from the pallet to prepare for shipping.

Conventionally, there have been many problems with the transportation and accumulation of long items such as pipe supports at material centers.
In other words, these long objects are transported by a cargo handling vehicle such as a forklift. The claw must be loaded with as many long objects as possible. However, such long items may not only be extremely dangerous, but also have the possibility of collapsing during transportation unless adequate retention and binding means are provided.
The loading process was also extremely time-consuming and inefficient.

In addition, since the accumulation is done by simply stacking up wooden rings, the load is applied directly to the long objects themselves.
For example, in the case of four stacked pipe supports, a heavy pressure of 800 kg x 4 = 3,200 kg will be applied to the lowest stage. Therefore, there was a risk that the pipe support itself would be deformed or damaged due to long-term storage and accumulation or repeated loads. Furthermore, when stacking, the forklift driver must either install or remove the hoops himself or another worker must do the work, which creates a lot of waste in the work flow of the workers. Katta. Furthermore, since the rings are made of wood, it is difficult to detect hidden rot and rot during long-term accumulation and storage.
Stacking was accompanied by danger, and therefore a certain amount of extra restricted area had to be created, which was extremely inconvenient from the standpoint of land conditions.

Not only that, but also in the so-called packaging that is accumulated and stored.
Due to the height difference and irregularity, and the difference in the size of the wheels, it is physically impossible to stack more than 6 layers using a general forklift (maximum lifting height of 3 m). The long items are usually tied together using steel bands, but these can break due to external pressure or corrosion, and there is a risk of them collapsing like an avalanche. Ta.

Furthermore, the disadvantage of requiring more labor and time than necessary for actual inspection during inventory cannot be denied. This invention solves the various problems in the conventional transportation and accumulation of long objects, and its purpose is to make the transportation and accumulation of long objects easy and efficient without requiring much effort and time. The purpose is to prepare for the transfer of accumulated long objects to transportation work vehicles easily and efficiently. can be,
Furthermore, the purpose is to prevent cargo from collapsing or collapsing like an avalanche on transportation vehicles or storage areas.
To avoid requiring an unduly large area for accumulation and storage, to be convenient for inventory taking, and to prevent an excessive load from being applied to long objects at the bottom even when stacked sufficiently high.

Therefore, this application, as in the illustrated embodiment,
A long object 3 is held between the inner pairs of the holding columns 1 on a pallet 2 having a plurality of pairs _P1 of holding columns 1 that stand upright on the upper surface of the support frame 4, and is transported to a predetermined place together with the pallet 2 as it is. , the holding column 1 of the pallet 2 supports and accumulates another pallet 2, and the pallet 2
For unloading long objects 3 accumulated through
On a pedestal 8 on which a plurality of pairs P ₂ of guide columns 10 are erected,
Each of the pallets 2 is placed together with a long object 3, and a pedestal 8 is placed at a position higher than the support frame 4 of the pallet 2.
A side beam 12 provided across the inner space of the guide pillar 10 of
and a swash plate 14 provided at the corner of the side beam 12 and the guide column 10, the long object 3 is secured to the support frame 4 of the pallet 2.
The present invention relates to a method for transporting and stacking elongated objects and preparing for shipping the accumulated elongated objects, which is characterized by holding and erecting elongated objects in a bundle having a polygonal cross section in a state where they are separated upwardly.

In this invention, a long object is held by a pallet having a pair of upright holding columns, transported by a work vehicle such as a forklift, and then accumulated and stored at a predetermined location. Therefore, since the holding columns of pallets serve both the function of holding long objects on their support frames and the support columns that support other pallets, long objects can be stacked high while remaining on pallets. can. The distance between the pairs of these holding columns is constant, and since there are multiple pairs,
Long objects can be firmly held and transported in large quantities, which is not only extremely efficient, but also eliminates the risk of the cargo collapsing during transport. Therefore, at the collection site, not only is there no need to install wheel rings and the troublesome work involved therein, but also the narrow collection and storage area can be used effectively. In addition, there is no longer any risk of long objects stored in piles collapsing like an avalanche. and,
Since the internal spacing of the holding columns is constant, the number of long objects held there can be kept constant, making inventory inspection easy.

In addition, in this invention, when unloading long objects accumulated via pallets, each pallet is transported together with the long objects by a forklift and placed on a pedestal on which a plurality of pairs of guide columns are erected. It is placed so that A side beam is placed between the guide columns of this pedestal at a higher position than the support frame of the pallet, and a swash plate is provided at the corner of the side beam and the guide column, so that the pallet can be placed on the pedestal. Then, the elongated objects are supported by the side beams and the swash plate and are erected in the form of a bundle with a polygonal cross section in a state that is spaced upward from the support frame of the pallet. Therefore, the work of binding a bundle of long objects with a steel belt can be performed extremely easily and in a short time, and the work of transferring the bundled long objects onto a truck can also be performed extremely efficiently.

Example As shown in Fig. 1, the pallet 2 consists of a rectangular support frame 4.
, two pairs of holding columns P ₁ , P ₁ erected at the four corner edges of the upper surface, and holding columns 1 . . . on the lower surface of the support frame 4.
...and a supported portion 5 that protrudes downward and expands into a downward bowl shape. Holding column 1... is support frame 4
The holding cylinders 6 provided at the four corners of the upper surface of the holding cylinder 6... can be replaced by selecting one of the required length.

Hold the long object 3 between the pairs P ₁ and P ₁ of the holding columns 1 of the pallet 2, and insert the claws 7' of the forklift 7 under the support frame 4 as shown in FIG. 2A. The pallets 2 are then conveyed to a predetermined location, and as shown in FIG. 2B, the holding columns 1 of the pallets 2 are used as support columns to be supported on the supported portions 5 of other pallets 2, and the pallets are accumulated or stacked in stages.

The long objects accumulated in this way are transported as pallets 2 by the forklift 7 from the place where they were accumulated to the unloading place as shown in FIG. 2C.
It is placed on the pedestal 8.

The pedestal 8 has a structure as shown in FIGS. 3 and 4, and the pallet 2 and the elongated object 3 are placed thereon as shown in the figures. That is, the pedestal 8 has two pairs of guide columns 10 at the four corner edges of the upper surface of the rectangular support frame 9.
P ₂ , P ₂ are erected and have four legs 11 below.

The upper ends of the guide columns 10 are bent so as to expand the pair _P2 of the guide columns 10 outward, as particularly shown in FIG. The side beams 12 extending between the pairs _P2 of the guide columns 10 are arranged higher than the side beams ₁₃ connecting the pairs P2. And guide pillar 10
A swash plate 14 is provided at the corner with the side beam 12 in each pair P ₂ . Therefore, the pallet 2 has a low side beam 13.
When placed on top, the long objects 3 are supported by the high side beams 12 and the swash plate 14, and are spaced upward from the support frame 4 of the pallet 2, forming a bundle with an octagonal cross section. . After binding this bundle of long objects 3 with a steel belt, insert the claw of the forklift between the support frame 4 of the pallet 2 and the long objects 3, lift only the long objects 3, and place the truck ( (not shown).

According to this embodiment, transportation and accumulation of long objects and preparation for shipping the accumulated long objects can be carried out safely, rationally, and efficiently.
