In FIG. 5, when the container replacement operation start signal is confirmed in step 1, the compactor I'A link control M17d is prohibited from replacing the container 8 located in front of the compactor 15 in step 2.

From step 3 to step 7, the container 8 on the transport vehicle 12 is stored a#! In the step of moving the containers 8 to the platforms 13a to 13g, if the container 8 is not confirmed on the transport vehicle 12H in step 3, the stay knobs 4 to 6
Skip this and move on to step 7.

On the other hand, when the container 8 is confirmed on the transport vehicle 12 by the Stesive 3, an empty storage platform is searched for in step 4, and the transport vehicle 12 is moved to the front of the empty storage platform searched for in step 5. In step 6, the container 8 on the carrier 12 is transferred to the empty storage platform.

In step 7, the carrier 12 moves to the second loading/unloading platform 7b.
, and in step 8 move to the front of the first loading/unloading table 7a.
When the container 8 is detected, the positioning device m l 2 e is extended in step 9 and the hook devices 12c, 12d are lowered in step 10.11.

Extend the telescopic boom 12b in step 12, and
In step 3, determine whether preparations for moving the empty container have been completed and confirm that the preparations are complete.In step 14, raise the 2, 2, and 7d. Hearing this, in step 16, the telescopic boom 7C provided on the first loading/unloading platform 7a is extended, and the container is moved to the second loading/unloading stage IIi! It is transferred to the mounting table 7b.

Furthermore, the two on the carriage 12 are moved by the stay and pull 17.

Next, identify the empty and actual containers and the empty and actual loading platform.
This will be explained with reference to FIG. 6 in relation to the loading/unloading operation.

First, in step 1, it is confirmed whether or not the container 8 has been loaded onto the first loading/unloading table 7a, and if it has been loaded, the container is placed on the first loading/unloading table 7a in step 2. Assuming that the container is empty, the contents of the memory corresponding to the loading/unloading table 7a of Sl are updated.

In step 3, move the container from the first loading/unloading table 7a to the second loading/unloading table 7b, and in step 4 check whether there is a container on the second loading/unloading table 7b. If there is, in step 5, there is no empty container on the first loading/unloading table 7a, and the second loading/unloading table 7a is placed on the second loading/unloading table 7a.
Assuming that there is an empty container in B, the contents of the corresponding memory are updated.

Next, in step 6, the container 8 is transferred from the 1jlt placement table 7b onto the transport vehicle 12 that has moved to the front of the second loading/unloading table 7b.

If the status knob 7 confirms that the container 8 has been picked up by the transport vehicle 12, then in step 8 it is determined that there is no container on the second loading/unloading platform 7b and that there is an empty container on the transport vehicle 12. Update the contents of memory.

In step 9, it is determined whether or not there is a container on the connection mounting table 14, and if there is no container, the transport vehicle 12 is moved to a position above the connection mounting stage 14 (step 10), and then the transport vehicle 12 The container 8 is moved to the stand 14 (step 11).

Then, in step 12, the container 8 is placed on the connection mounting table 14.
If the transfer is confirmed, the memory contents are updated in step 13.

Specifically, there is no container in the transport vehicle 12, and the connection@
While the corresponding memory is updated assuming that there is an empty container on the H platform 14, if it is determined in step 9 that there is an empty container, any one of the searched empty storage tables (for example, the storage platform 13a and the following image) is updated. transport vehicle 1 until the front of
2 (step 14), and the container is moved from the transport vehicle 12 to the storage platform 13a (step 15).
When it is confirmed that the container is placed on the storage and placement table 13a (stay, block 16), the memory contents are updated in step 17.

That is, it is assumed that an empty container is placed on the storage platform 13a and there is no container on the transport vehicle 12, and the stored contents of the corresponding memory are updated.

On the other hand, the compactor 15 fills the container on the contact table 14 with garbage.

Then, in the stay 18, it is determined whether the container has expired or not, specifically, as described above, it is determined whether the set number of times or the set pressure per person has been reached.

When the expiry date is reached, the transport vehicle 12 is moved to the position of the connection mounting table 14 in step 19, and the connection mounting table 1 is moved in step 20.

After confirming that there is a container on the conveyance platform 34E12 using the stainless knob 21, in step 22, the conveyance vehicle 1
21-, is loaded with a container, and in addition to being a real container, there is also a connection [! The memory contents are updated to indicate that there is no container on the stand 14)-.

Next, the transport vehicle 1 is moved to a position in front of an arbitrary one of the searched empty storage platforms (for example, assumed to be storage platform 13g below).
2 (step 23).

The actual container is moved from the transport table bundle 12 to the empty storage and mounting table 13g (step 24).

When it is determined in step 25 that the container 8 has been moved onto the empty storage platform 13g, in step 26, the actual container is placed on the storage platform 13g. The memory contents are updated to indicate that there is no container in the transport vehicle 12.

As described above, the container 8 carried in from the carry-in temporary stand 7a is set as an empty container, and the container 8 of the transport trolley 12
Container information # (empty container) is tracked and updated every time the container is moved to the empty loading table 7, and on the other hand, the container 8 packed with garbage by the compactor 15 on the connected loading table 14 is set as a real container. , this container information i (actual container) is updated every moment following the movement of the transport vehicle 12.

In this way, the contents of the memory corresponding to each loading table that are updated every moment are read, and once the presence or absence of a container and whether the container on the loading table is empty or actual are detected and determined, it is determined to which empty loading table the empty container should be moved. , or which actual container is to be moved is determined at random or by searching according to a ranking assigned to each tray table in advance.

In addition, on the nut flow side, the detection means for detecting the presence or absence of a container on each mounting table is composed of an electric contact (limit switch), and the discrimination means for determining whether a container is empty or not is processed by software. It is also possible to change the detection means and the discrimination means to a load cell. In other words, it detects that the load acting on the load cell has reached a predetermined value or more and detects that there is a container on the mounting table, and also detects that the load acting on the load cell has reached the container tare weight or more. It is also possible to identify the container on the mounting table as a real container by checking the actual container.Furthermore, it is also possible to match the load cell and photoelectric switch with buttons.

Furthermore, on the bold side, containers are carried in and detected by a moving trolley 5 installed on the first floor above ground, but instead of using a crane 9, cargo handling vehicles carry in and out containers at the container moving section tb. In this case, separate mounting tables may be installed for loading and unloading.

In addition, in the embodiment, the movement of the container 8 is carried out using a carrier 12 and a telescopic boom 12a provided on the carrier bundle 12.
, 12b and hook device 12c.

12d, but the present invention is not limited to this. For example, the container may be moved by a slat conveyor and a container transfer device that transfers the container in a direction perpendicular to the direction in which the container 8 is moved by the slat conveyor.

(Effects of the Invention) As described above, according to the present invention, an empty container carried into a carry-in loading table can be automatically transferred by searching the empty loading table, and an actual container on each loading table can be searched. Since the workpiece is automatically transferred to the loading and unloading table, erroneous operations are eliminated, and at the same time, it is possible to improve the working vehicle and save labor.
