Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container stacking method and a container stacking auxiliary tool, and more particularly to a container stacking method for stacking and transporting containers on a bed of a container vehicle. , And a container stacking aid.

[0002]

2. Description of the Related Art With the recent increase in production activity, the amount of waste such as cinders, sludge, and waste oil discharged from factories is rapidly increasing, and the types of waste are diversifying. It is in. Therefore, strict standards have been set regarding the treatment methods for treating these wastes by laws and ordinances, and the companies that discharge wastes are obliged to perform treatments based on these standards. However, in order for each trader to independently carry out the processing based on the standard, a great deal of cost is required, such as newly installing equipment for processing. Therefore, in many cases, a waste disposal contractor who specializes in treating these wastes outsources the disposal. As a result, the trader can reduce the processing cost.

The waste treatment company collects the waste discharged from the factory of the contracted company in a container or the like, transports the container in which the waste is accumulated from the factory to the waste treatment facility,
We are doing that. At this time, the waste treatment company
Repeatedly arranging some empty containers in a factory in advance, and when waste discharged from the factory is accumulated in the container, collect it and relocate an empty container in the factory instead. Is going.

In addition, at this time, in order to install an empty container in a factory or to transport a container in which waste is collected to a waste treatment facility, a facility capable of loading and unloading the container by itself (hereinafter referred to as "equipment") , A loading / unloading device) is often used. Here, the unloading device, for example, a slider mechanism using a hydraulic control type cylinder,
It is composed of a crank mechanism formed by a plurality of link members and pins, etc., and by providing a hook part that can engage with a hooking tool attached to the container at the follower part, loading and unloading of the container only by the container vehicle Is. In other words, since other equipment such as a crane is not required, the container unloading work can be performed without limiting the container unloading place.

By the way, a plurality of the above-mentioned containers may be prepared for one container vehicle, and the waste disposal company systematically plans the route of each container vehicle around the factory and the timing of collection. By making arrangements, efficient container transportation is carried out.

[0006]

However, when carrying a plurality of containers by a container vehicle, tens to hundreds of containers may be assigned to one container vehicle. In general, container vehicles can only load one container at a time, so for example, after allocating one empty container in a factory, there is a waste container in the factory. Absent,
That is, if there is no container to be collected, leave the container unloaded and move to another factory with a container with waste accumulated, or go to a waste treatment facility to transport an empty container again. I had to come back. For this reason, the container vehicle wastes the return trip, and additional costs such as personnel costs and transportation costs were required.

Further, when a plurality of containers are collectively arranged in a large factory, it is inefficient to carry the containers by one container vehicle, and therefore it is necessary to carry out by a plurality of container vehicles. was there.

That is, since the number of containers that can be loaded by a container vehicle at one time is limited to one, a waste disposal company systematically decides the route along which the container vehicle goes around the factory and the timing of collection. Even so, there was a limit to how efficiently it could be transported.

Conventionally, equipment such as a crane has been used as a method for stacking containers,
These are inconvenient because the places where they are stacked are limited.

Therefore, in view of the above situation, the present invention provides a container stacking method and a container stacking auxiliary tool capable of stacking containers in multiple stages only by the container cars and further stacking the containers on the container cars. This is an issue.

Next, a container stacking method 1 using the container stacking auxiliary tool 2 of the first embodiment will be described with reference to FIGS.
It will be described based on. First, the hooking wall 32 of the container 6
And the rear end of the container vehicle 8 face each other (Fig. 5
In (a)), the hook portion 50 is engaged with the hooking tool 31 of the container 6.

At this time, the container 6 is hung by the loading / unloading device 44 on the side of the hook wall 32 on which the hook 31 is hooked, and the container 6 is in an inclined state. Then, the container 6 is pulled by the loading / unloading device 44 while being inclined, and the sliding frame 10 of the container 6 comes into contact with the roller portion 29 of the container vehicle 8 (FIG. 5B). Then, when the container 6 is further pulled, the roller portion 29 rotates, the sliding frame 10 slides on the roller portion 29,
The container 6 is smoothly pulled by the loading platform 27.

Thereafter, the legs 39 of the container 6 and the sliding frame 10 are respectively placed on the front support table 42 and the rear support table 43 of the loading platform 27, and the container 6 is loaded on the loading platform 27 (see FIG. c)) (step S1).
Here, step S1 corresponds to the first loading step of the present invention.

Next, the container vehicle 8 is moved (step S2), and the rear end of the container vehicle 8 is the door wall 3 of the container 7.
Set to the state facing 6. Then, the container 6 is slightly pushed out to the rear of the loading platform 27 (corresponding to the right direction on the paper surface in FIG. 6) by the unloading device 44, and the protruding portion 28 of the sliding frame 10 of the container 6 projects from the roller portion 29 ( 6 (a)).

At this time, the sliding frame 10 of the container 6
The bottom surface of the container is lower than the top surface of the container 7 placed on the flat ground 30. Therefore, when the container 6 is pushed out by the loading / unloading device 44, it becomes difficult to stack the container 6 on the container 7, such as the door wall 36 of the container 6 collides with the door wall 36 of the container 7. .

At this time, the container 6 is in an inclined state. Then, the support member 4 is mounted on both side walls 15 of the container 7 on the side of the door wall 36, and the loading / unloading device 44 is used to load the container 6
Wholesale from a tilted state to a horizontal state. As a result, the pair of sliding frames 10 of the container 6 are respectively fitted to the second support portions 16 of the support member 4, and the container 6 is supported from below. That is, the container 6 is stacked substantially horizontally on the container 7 by the supporting sliding member 3 and the supporting member 4 (FIG. 7C, step S5).

By the above steps, the container 6 is stably stacked on the container 7. Here, step S
Steps 2 to S5 correspond to the stacking step of the present invention.

Next, the stacking container 55 including the containers 6 and 7 stacked in the stacking step is fixed by the band member 51 (step S6). For fixing with the band member 51, first, one band member 51 is prepared, the band hook portion 53 is hooked on the first hook portion 37 of the container 7, and the side wall 15 of the stacking container 55 is wound.
Next, the other band member 51 is prepared, the band hook portion 53 is hooked on the second hook portion 38 of the container 7, and the band hook portion 53 is wound around the stacking container 55 via the hooking wall 32 of the container 6. As a result, the state where the containers 6 are stacked on the container 7 is maintained. Here, step S6 corresponds to the fixing step of the present invention.

By the way, in the stacking container 55 fixed in the fixing step, as shown in FIG. 7D, the hooking wall 32 of the lower container 7 is located on the opposite side to the rear end of the container vehicle 8. is doing.

Therefore, the container vehicle 8 is moved so that the rear end of the container vehicle 8 is located at a position facing the hooking wall 32 of the container 7 (FIG. 8 (a), step S7). Then, similar to the first loading step, the hook portion 5 of the loading / unloading device 44.
0 is engaged with the hooking tool 31 of the container 7 and towed (FIG. 8).
(B)). At this time, since the container 6 and the container 7 are fixed by the band member 51, the stacking container 55 is loaded on the loading platform 27 (FIG. 8C, step S).
8). Here, step S7 and step S8 correspond to the second loading step of the present invention.

Through the above steps, the container vehicle 8 is used to stack the containers 6 on the containers 7, and
The stacking container 55 can be loaded on the container vehicle 8. In addition, the stacking container 5 loaded on the container vehicle 8
In case of loading 5 from loading platform 27 to flat ground 30,
The above steps may be reversed in order.

As described above, the container stacking method 1 is the container stacking auxiliary tool 2 and the container vehicle 8 of the first embodiment.
By using the, the containers 6 can be stacked on the container 7 and further loaded on the container vehicle 8 to be transported. Then, the containers 6, 7 are carried out by the container vehicle 8.
After they are collectively transported to a factory or the like, the stacking container 55 can be unloaded only by the container vehicle 8. Therefore, for example, when transporting a plurality of containers to a factory, one container vehicle 8 is less likely to be reciprocated or shared among a plurality of container vehicles to be transported, and a plurality of containers can be efficiently transported in a short time. It becomes possible to carry.

Further, since the transport efficiency of the container vehicle 8 is improved more than ever, for example, the conventional container vehicle 8 is
It is possible to further increase the number of containers 6, 7 and the like allocated to one container vehicle 8 without increasing the number of containers. Therefore, the containers 6 and 7 can be distributed more than ever, and a large amount of waste can be transported.

Further, one operator can perform the series of steps (work) of the container stacking method 1 described above. Therefore, it is not necessary to increase the number of workers for each container vehicle 8, which does not lead to an increase in labor costs.

By the lifting member 5, the bottom surface of the sliding frame 10 of the container 6 can be lifted higher than the upper surface of the lower container 7. Therefore, by raising the lifting member 5 to a high position, the container 6 can be easily stacked on the container 7.
