Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic container changing device in a garbage processing facility installed in a building or the like.

(Prior art) In general, garbage processing equipment performs a series of operations from carrying in and storing empty containers, packing the garbage in a compactor, and even carrying out the actual containers after packing. is set up.

Conventionally, an empty container brought in by a cargo handling vehicle is temporarily stored on a storage platform, and then connected to a compactor and filled with garbage.

On the other hand, the actual container filled with garbage is removed from the compactor, temporarily stored on a storage platform, and then transported by a cargo handling vehicle.

(Problems to be Solved by the Present Invention) However, such a replacement work in which an empty container is transferred from a storage mounting table to a connection mounting table, and a replacement work in which an actual container is transferred from a connection mounting table to an empty storage mounting table, is as follows. The operator who maintains and manages the garbage processing equipment must understand the contents of each loading table, that is, whether or not a container is placed on each loading table, and whether the loaded container is an empty container or a real container. The target container was moved to a specified location.

Therefore, there is no particular problem with small-scale garbage processing equipment, but with large-scale equipment, the control section is located in a remote location, making it difficult to understand the entire equipment contents. It is very possible, but there is also a risk of erroneous operation.

The present invention has been made in view of the above points, and aims to save labor, improve operational efficiency, and prevent the occurrence of erroneous operations by automatically transferring containers between storage and connection platforms. The present invention provides an automatic container replacement device for garbage processing equipment that can be used in a garbage processing facility.

(Means for Solving the Problems) A first aspect of the present invention provides a compactor, a connecting platform for connecting a container to the compactor, and a loading/unloading platform for loading and unloading the container between a cargo handling vehicle and a cargo handling vehicle. , a storage platform that is placed separately from these platforms and stores the container, and a container that allows the container to be moved directly or indirectly between the loading/unloading platform and the connected platform. The garbage processing equipment includes a moving device and a discriminating means for discriminating whether the container on each of the mounting tables is empty or full, and the container moving device moves the empty container on the storage mounting platform based on a discrimination signal from the discriminating means. The device is automatically transferred to the connecting table via the connecting table.

Further, the second aspect of the present invention is the garbage processing equipment, which includes a detection means for detecting the presence or absence of a container on each of the storage mounting tables, and based on a detection signal from the detection means, A real container is automatically transferred onto an empty storage platform via a container moving device.

(Operation) (First invention) Empty containers placed on each storage/mounting table are recognized by the discrimination signal from the discrimination means, and one of the empty containers is recognized by the discrimination signal from the discrimination means.
empty containers are searched at random based on the discrimination signal or according to the order assigned to the mounting table in advance. When an empty container is retrieved, the container moving device moves to the storage platform on which the empty container is placed, and transfers the empty container on the storage platform to the container moving device. Thereafter, the container moving device moves to the front of the connecting platform, and transfers the empty container from the container moving device to the connecting platform.

(Second invention) After the container moving device that has moved to the front of the connecting platform transfers the actual container from the connecting platform to the container moving device, the container moving device detects an empty storage platform on which no container is placed. The search is performed at random based on the detection signal from the table or according to the order assigned to the mounting table in advance. When an empty mounting table is searched, the container moving device is moved to the searched storage mounting table, and the container on the container moving device is transferred to the storage mounting table.

Various signals etc. are input from.

Next, the moving operation of the transport vehicle 12 will be explained based on the flowchart shown in FIG.

In FIG. 5, a container movement permission signal is confirmed in step 1, and when this signal is confirmed, a control signal is sent to the loading/unloading operation panel 18 in step 2 to prohibit the container loading/unloading operation.

Steps 3 to 6 show steps for preparing to load the container 8 onto the transport vehicle 12. If the container 8 on the transport vehicle 12 is not detected in step 3, the process skips to step 7.

On the other hand, when the container 8 is detected on the transport vehicle 12, an empty loading table is searched for in step 4, and the transport vehicle 12 is moved to in front of the empty loading table in step 5. Then, in step 6, the container 8 is transferred onto this empty mounting table.

In step 7, the carrier 12 is moved to the connection platform 14, and in step 8, the container on this connection platform 14, the so-called real container, is moved to the carrier 12.
move it upwards. In step 9, an empty mounting table is searched for as in step 4 described above, and in step 10, the carrier 12 is moved to the front of the empty mounting table.

Then, the storage mounting table 13 selected in step 11
Move the container 8 upwards from a to 13g.

Steps 12 to 16 are steps for searching for empty containers stored on the storage mounting tables 13a to 13g and transporting them to the connection mounting table 14.In step 12, an empty container is searched, and in step 13, The carrier 12 is moved to the front of the empty container, and the empty container is transferred onto the carrier 12 in step 14.

In step 15, the carrier 12 is moved to the front of the connecting table 14, and in step 16, the empty container is moved onto the connecting table 14.

When a new empty container is moved onto the connection platform 14 in this manner, a container connection permission signal is issued to the compactor-related control section 17d in step 17.

Note that if the container movement permission signal is not output in step 1, the process ends without executing each of the above steps.

Next, the discrimination between an empty and actual container and an empty and actual mounting table will be explained with reference to FIG. 6 in relation to the loading/unloading operation of the container 8.

First, in step 1, it is confirmed whether or not the container 8 has been carried into the first carrying-out/loading table 7a.
A container is placed on the container a, and assuming that it is an empty container, the contents of the memory corresponding to the first loading/unloading table 7a are updated.

Next, in step 3, the first loading/unloading table 7a
The container is moved from the container to the second loading/unloading table 7b, and in step 4 it is determined whether or not there is a container on the second loading/unloading table 7b. It is assumed that there is no empty container on the mounting table 7a and that there is an empty container on the second loading/unloading table 7b, and the stored contents of the corresponding memory are updated.

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

If it is confirmed in step 7 that the container 8 has been picked up on the transport vehicle 12, it is determined in step 8 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 platform 14. If there is no container, the transport vehicle 12 is moved to the front position of the connection platform 14 (step 10), and then the connection platform is removed from the transport vehicle 12. Stand 14
Move container 8 to (step 11). Then, in step 12, the container 8 is placed on the connection platform 14.
When the transfer is confirmed, the memory contents are updated in step 13.

Specifically, the corresponding memory is updated assuming that there is no container on the transport vehicle 12 and that there is an empty container on the connected loading table 14. If it is determined in step 9 that there is an empty container, the searched empty storage is updated. The transport vehicle 12 is moved to a position in front of an arbitrary one of the mounting tables (for example, assumed to be the storage mounting stage 13a below) (step 14), and the storage mounting stage 13 is moved from the transport vehicle 12 to the storage mounting stage 13a.
When the container is moved to storage platform 13a (step 15) and the placement of the container on the storage/mounting table 13a is confirmed (step 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 container on the connection mounting table 14 is filled with garbage from the compactor 15.

Then, in step 18, it is determined whether the container has expired or not, specifically, whether the set number of times or the set pushing pressure has been reached as described above.
When the expiry date is reached, the carrier 12 is moved to the position of the connecting platform 14 in step 19, and the container is moved from the connecting platform 14 to the carrier 12 in step 20.

When it is confirmed in step 21 that there is a container on the transport vehicle 12, in step 22, it is confirmed that the container is mounted on the transport vehicle 12 and that the container is a real container, and that there is no container on the connection platform 14. , updates the memory contents.

Next, the transport vehicle 12 is moved in front of an arbitrary one of the searched empty storage platforms (for example, assumed to be the storage platform 13g below) (step 23), and the actual container is transferred from the transport vehicle 12 to the empty storage platform 13g. (Step 24).

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

As described above, the container 8 carried in from the carry-in platform 7a is set as an empty container, and
Every time the upper container 8 is moved onto the empty loading table, the container information (empty container) is tracked and updated.
On the other hand, the container 8 filled with garbage by the compactor 15 on the connection platform 14 is set as a real container, and this container information (real 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 real are detected and determined, the empty container on which empty loading table should be moved or The empty mounting table on which the actual container is to be moved is determined by searching at random or according to a ranking assigned to each mounting table in advance.

In this embodiment, 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 determination means for determining whether a container is empty or real is processed by software. It is also possible to change the 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. The container on the mounting table may be determined to be a real container. Furthermore, it is also possible to combine a load meter and a photoelectric switch.

Furthermore, in this embodiment, the containers are carried in and out using the moving trolley 5 installed on the first floor above ground, but instead of using the crane 9, the cargo handling vehicle carries the containers in and out at the container moving section 1b. In this case, separate mounting tables may be installed for loading and unloading.

In addition, in the embodiment described above, the container 8
The movement of the vehicle is carried out using a carrier 12, telescopic booms 12a and 12b provided on the carrier 12, and a lifting device 1.
2c and 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 conveyor in a direction perpendicular to the direction in which the container 8 is moved by the slat conveyor. It's okay.

(Effects of the Invention) As described above, according to the present invention, an empty container placed on a storage platform is searched for and automatically transferred to a connection platform, and an actual container on a connection platform is automatically transferred to the storage platform. Since an empty storage mounting table is searched and automatically transferred to the storage mounting table, it is possible to eliminate erroneous operations and at the same time improve work efficiency and save labor.
