DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for transporting a plurality of cylinders in an upright state and transporting the cylinders in a frame-type structure, and more particularly to a pallet having a structure for preventing cylinders from tipping over during transportation. .

[0002]

2. Description of the Related Art Conventionally, in a gas filling factory for filling an empty gas cylinder collected from a gas distributor or the like,
When the above-mentioned empty gas cylinders are filled with gas or when the gas cylinders after gas filling are transported to the above-mentioned gas distributors, a plurality of gas cylinders are placed and stored upright on the bottom plate of the frame-structured transport pallet. However, the transport pallet is transported while lifted by a forklift or the like.

[0003]

Normally, this type of transport pallet is constructed so that, for example, 16 gas cylinders can be stored at the same time. For this reason, when only 12 pallets are stored in the pallet, a wide gap is formed between the frame of the pallet and the gas cylinder, which may cause the gas cylinder to fall down in the pallet and be damaged during transportation. There is a problem that there is. SUMMARY OF THE INVENTION It is an object of the present invention to reliably prevent a cylinder from overturning during transport even when the number of stored cylinders is small.

[0004]

In order to achieve the above object, the present invention is configured as follows, for example, as shown in FIGS. [Invention of Claim 1] A bottom plate 1 on which a plurality of cylinders G can be placed in an upright state, and column members 2, 3, 4 extending upward from four corners of the bottom plate 1
And a frame member for connecting the column members 2, 3, 4 and 5 to each other, and a frame-type transfer pallet having at least one surface FB in the front-rear direction formed to be openable. The upper ends of the pillar members 2 and 5 (the pillar members 3 and 4) are connected to each other by a pair of left and right front and rear cross members 6 and 7, and the support shaft 15.1 is attached to at least one of the front and rear cross members 6 and 7.
6 are arranged along the cross members 6 and 7, and the support shaft 15
Two cylinder holding members 13 and 14 are arranged between the front and rear cross members 16 and 16 facing each other, and at least one of the cylinder holding members 13 and 14 of the cylinder holding members 13 and 14 is provided. One end is supported by the support shafts 15 and 16 so as to be able to swing up and down and move back and forth, and the other end of the cylinder holding bars 13 and 14 is engaged with the front and rear bars 6 and 7. It is configured to be removable. [Invention of Claim 2] In the configuration of Claim 1, the gate plates 11 and 12 are arranged on the openable surface FB, and a hook-like shape is provided at an intermediate height position of the open surface FB. Of the hook member 32,
The upper ends 28 and 29 of the gate plates 11 and 12 are detachably supported by the hook members 32, and the lower ends 26 and 27 of the gate plates 11 and 12 are vertically movable and swingable at the height of the bottom plate 1. It is pivotal.

[0005]

The present invention operates as follows, for example, as shown in FIGS. [Invention of claim 1] By swinging the cylinder members 13 and 14 upward about the support shafts 15 and 16 to make them vertical (see the two-dot chain line diagram in FIG. 2), the open surface F. B is opened, and the cylinder G can be loaded and unloaded from the open surfaces FB. Then, the cylinder members 13 and 14 are slid along the support shafts 15 and 16 and are swung downward at a position where there is almost no gap between the cylinder G and the cylinder G placed and stored on the bottom plate 1. The cylinder G is engaged with the front and rear cross members 6 and 7 (see the solid line diagram in FIG. 6) to mount the cylinder G.
However, it is prevented from falling down during conveyance by being pressed by the above-mentioned cylinder members 13 and 14. [Invention of Claim 2] By locking the upper ends of the gate plates 11 and 12 by hooking the hook members 32, the gate plates 11 and 12 are housed in the upright state on the front and rear surfaces FB (FIG. 2). State). Then, the gate plates 11 and 12 are lifted, the upper ends of the gate plates 11 and 12 are detached from the hook members 32, and the gate plates 11 and 12 are tilted in the front-rear direction. The upper ends of 11 and 12 contact floor U. Thus, a slope from the bottom plate 1 to the floor surface U is formed by the gate plates 11 and 12.

[0006]

The present invention has the following effects because it is constructed and operates as described above. [Invention of claim 1] By sliding only the cylinder member for holding down the cylinder, the cylinder is held down by the member for holding cylinder for preventing the cylinder from falling down. The size is maintained. Therefore,
Regardless of the number of the cylinders, the stability of the transport pallet can always be kept high. Also, when the cylinder is placed on the transport pallet, only the cylinder member for holding the cylinder is required to be operated, and there is no operation such as moving the column member. Time and labor can be reduced, and the work time can be shortened. Moreover, since the cylinder does not protrude from the transport pallet, it is possible to prevent the cylinder from being hit by other objects during the transport. [Invention of Claim 2] Just by hooking the upper end of the gate plate to the hook member, the gate plate is stored in the front and rear surfaces in an upright state, and only by lifting the gate plate, the upper end of the gate plate is hooked. As a result, the slope can be formed on the gate plate, so that it is not necessary to fix the gate plate to the column member by fastening means such as bolts or to remove the bolts. Therefore, the gate plate can be stored in the front and rear surfaces with a simple operation, and the slope can be formed by the gate plate, so that the efficiency of the operation related to the transport of the cylinder can be increased.

The cylindrical right support shaft 16 is attached so as to extend forward from the rear surface B. Then, the right support shaft 16 is loosely fitted into the loose fitting hole formed in the connecting member 19 of the rear rod 14. This allows the rear rod 14 to swing about the right support shaft 16 and to slide in the axial direction of the right support shaft 16.

Further, a projection protruding downward from the extension piece 19a of the rear rod 14 can be engaged with a notch 21 formed in the rear half of the right angle 7, and the rear rod 14 The projection 23 projecting downward from the tip is made engageable with a fitting hole 24 formed at a predetermined interval in the rear half (upper side in FIG. 1) of the left angle 6. Note that rubber, synthetic resin, or the like is attached to the inside of the rods 13 and 14 as a cushion material.

Next, the structure of the gate plates 11 and 12 will be described with reference to FIGS. For convenience of explanation, the front gate plate 11 will be described, but the rear gate plate 12 is configured similarly to the front gate plate 11.

Shafts 26 and 27 are provided at the lower left and right of the front gate plate 11, respectively.
Are provided, and locking members 28 and 29 are provided on the left and right ends, respectively. On the other hand, the lower end of the side surfaces 2a and 3a of the left front column member 2 and the right front column member 3 facing each other is provided with the shaft 26
A guide member 31 that allows only vertical movement of 27 is provided. The guide members 31 pivotally support the shafts 26 and 27 so that they can move up and down and swing freely.

When the shafts 26 and 27 are at the lower end of the guide member 31, the lower end of the front gate plate 11 is substantially at the same height as the bottom plate 1. The guide member 31 is open at the upper rear side so that the shafts 26 and 27 can be removed from the opening.

When the upper end of the front gate plate 11 is pulled forward (to the left in FIG. 4) when the locking member 28 (29) is raised to the upper end of the hook member 32, the locking member 28 ( When the hook 29 is disengaged from the hook member 32 and is tilted forward, the front gate plate 11 rotates about the shaft 26 (27), and the upper end of the front gate plate 11 contacts the floor surface U.

At this time, the shaft 26 (27) of the front gate plate 11
Is returned to the lower end of the guide member 31 by its own weight, so that the lower end of the front gate plate 11 is at the same height as the bottom plate 1, and as shown in the two-dot chain line diagram of FIG.
Thereby, a slope from the bottom plate 1 to the floor surface U is formed.

Next, the loading operation of the gas cylinder G on the above-mentioned transport pallet will be described with reference to FIGS. 1, 5 and 6. FIG. First, the rods 13 and 14 are swung upward to stand upright (see a two-dot chain line in FIG. 5). further,
The gate plates 11 and 12 are respectively laid down and the floor plate U
(See the two-dot chain line in FIG. 5).

In this state, the operator drags the gas cylinder G up to the bottom plate 1 along the slopes of the gate plates 11 and 12. Then, after the mounting and storage of the 16 gas cylinders G on the bottom plate 1 are completed, the rods 13 and 14 are respectively lowered and the projecting portions 2 of the connecting members 19 of the rods 13 and 14 are lowered.
2 are engaged with the notches 21 of the angles 6 and 7, respectively, and the projections 23 of the rods 13 and 14 are engaged with the fitting holes 24 of the angles 6 and 7, respectively, thereby fixing the rods 13 and 14 (FIG. 2 and the solid line diagram in FIG. 5).

Further, the upper ends of the gate plates 11 and 12 are lifted and swung upward, and the locking members 28 and 29 of the gate plates 11 and 12 are inserted into the hook members 32, and the gate plates 11 and 12 are left as they are. When the gates 11 and 12 are lowered, the shafts 26 and 27 of the gate plates 11 and 12 move down in the guide member 31, and the locking members 28 and 29 of the gate plates 11 and 12 move together with the shafts 26 and 27. The gate plates 11 and 12 are lowered in the hook member 32 of FIG.

Thereafter, a fork of a forklift is inserted into the gap S between the bottom plate 1 and the floor surface U, and the pallet for main transport is lifted and transported. At this time, the gas cylinder G is pressed down by the rods 13 and 14, and the gas cylinder G being transported is prevented from falling.

As shown in FIG. 6, for example, when 12 gas cylinders G are placed on the bottom plate 1 and conveyed, the rear rod 14 is fixed at the position of the rear surface B while the rear cylinder 14 is fixed. The front rod 13 is erected, and the front gate plate 11 is tilted to form a slope from the bottom plate 1 to the floor surface U. Then, the twelve gas cylinders G are placed and stored on the bottom plate 1 in a state where the gas cylinders G are moved rearward.

Thereafter, the front rod 13 is slid and moved to a position where there is almost no gap between the front cylinder 13 and the gas cylinder G. At this position, the front rod 13 is lowered, and the protruding portion 22 of the front rod 13 is moved. The front rod 13 is fixed at that position by engaging the notch 21 of the left angle 6 and the projection 23 of the front rod 13 with the fitting hole 24 of the right angle 7.

Thereafter, the front gate plate 11 is raised and locked by the hook members 32, a fork of a forklift is inserted into the gap S, and the main transport pallet is lifted and transported. Also in this case, since there is almost no gap between the rods 13 and 14 and the gas cylinder G, the gas cylinder G does not fall down during transportation.

As described above, the rods 13 and 14 are appropriately slid and moved according to the number of the gas cylinders G placed on the bottom plate 1 so that the gas cylinders G and the rods 13 and 14 are fixed so as to cause almost no gap. By doing so, it is possible to prevent the gas cylinder G from falling over and being damaged during transportation.
When eight gas cylinders G are placed on the bottom plate 1, the gas cylinders G are placed in two central rows in the front-rear direction of the bottom plate 1, and the rods 13 and 14 are slid to move the gas cylinders G together. By fixing the pallet so that there is almost no gap between the rods 13 and 14, it is possible to prevent the gas cylinder G from tipping over while maintaining the weight balance of the pallet.

The above embodiment can be modified as follows. In the above embodiment, the front surface F and the rear surface B are configured to be openable, but only the front surface F may be openable. In the above embodiment, both the rods 13 and 14 can be disengaged from the angles 6 and 7.
It is also possible that only the third member 3 can be disengaged from the angle 7 and the rod 14 is fixed between the angles 6 and 7 by a bolt or welding.

In the above embodiment, the parts such as the rods 13 and 14 and the angles 6 and 7 have the same shape in order to share the parts. A support shaft may be formed so as to extend to the first support shaft, and the rods 13 and 14 may be loosely fitted to this one support shaft. In this case, the notches 21 are formed at predetermined intervals over the entire length of the left angle 6, and the fitting holes 24 are formed at predetermined intervals over the entire length of the right angle 7.
