Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cooling a control panel mounted on a stacker crane.

[0002]

2. Description of the Related Art As a conventional special automatic warehouse, for example, about 60
In a high temperature environment of ° C, there is a stacker crane configured to load and unload loads on a rack. Such an automatic warehouse stores, for example, a steel material that has just been manufactured in a steel mill, and since the temperature inside the warehouse is high, the temperature inside the control panel mounted on the stacker crane is likely to be high. Therefore, in order to secure the performance of the electronic circuit provided in the control panel, it is necessary to cool the control panel.
However, there is currently no small cooling device that can sufficiently cool the control panel in a high temperature environment of about 60 ° C in a limited space such as the stacker crane. There is no choice but to place it in.

[0003]

However, when the control panel originally provided on the stacker crane is arranged on the ground, the control data is transmitted between the control panel and the stacker crane. Due to the necessity of providing a communication system and the like, there arise problems that the configuration is complicated and the cost is high.

An object of the present invention is to provide a cooling device capable of effectively cooling a control panel of a stacker crane with a simple and inexpensive structure.

[0005]

In a cooling device for a control panel of a stacker crane according to the present invention, a cooling nozzle is provided at the origin position, and a connection port that can be connected to the cooling nozzle is formed in the control panel on the stacker crane. However, each time the stacker crane returns to the original position, the cooling nozzle is connected to the connection port to supply cooling air into the control panel.

The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a side view showing a cooling device for a control panel of a stacker crane according to an embodiment of the present invention, and FIG. 2 is a plan view showing a schematic configuration of an automated warehouse having the cooling device of FIG.

The stacker crane 10 travels along a travel route provided between the shelves 11 and 12 to carry out loading and unloading work of luggage. That is, the stacker crane 10 includes the shelf 1
Between Nos. 1 and 12, the rails 13 on the ground and the guide rails 14 on the ceiling side travel to carry the parcels P received from the loading station 15 and carry the racks 11,
The packages P stored in a predetermined position 12 or taken out from the shelves 11 and 12 are delivered to the loading station 15. The loading station 15 includes shelves 11, 1
It is provided on one end side of 2, that is, on the origin side of the traveling path of the stacker crane 10, and temporarily loads the load P.

In the stacker crane 10, the lifting platform 1
6 is supported by masts 17 and 18 so as to be able to move up and down.
The lift 16 is provided with a slide fork 19 for transferring the load P to the shelves 11, 12 or the loading station 15. Further, the stacker crane 10 is equipped with a control panel 20 for controlling the operations of the lifting platform 16 and the slide fork 19, and a motor 23 for causing the stacker crane 10 to travel.

A stopper 24 is provided at the origin of the traveling path of the stacker crane 10. Stacker crane 10
Returns to the origin every time a predetermined transfer operation is completed, and abuts the stopper 24 at this origin position to stop. In this stopped state, the cooling device operates as described later, and the inside of the control panel 20 mounted on the stacker crane 10 is cooled.

In the present embodiment, the cooling device has a cooling nozzle 31 provided near the origin and a cooling air supply source 32 provided at a place distant from the origin. The cooling nozzle 31 and the cooling air supply source 32 are connected via a pipe 33. The cooling nozzle 31 projects in the horizontal direction and faces the stacker crane 10 side. Stacker crane 1
The control board 20 on the 0 is provided with a connection port 34 that can be connected to the cooling nozzle 31. The connection port 34 communicates with the inside of the control panel 20 via an air passage (not shown) in the column 21 provided below the control panel 20.

Valves (not shown) are provided on the cooling nozzle 31 and the connection port 34, respectively. Each valve is
The valve is opened when the cooling nozzle 31 and the connection port 34 are connected to each other, whereby the cooling air pressure-fed from the cooling air supply source 32 is supplied into the control panel 20 through the cooling nozzle 31 and the connection port 34. To be done. Further, each valve is closed when the cooling nozzle 31 and the connection port 34 are open to each other. Therefore, in this state, the cooling air is not discharged from the cooling nozzle 31 and the connection port 34 is also closed.

The operation of the apparatus of this embodiment having the above configuration will be described. When the stacker crane 10 is stopped at the position (origin) of the loading station 15 for delivery of the load P, the cooling nozzle 31 and the connection port 3 of the control panel 20.
And 4 combine. Therefore, at this time, the valves of the cooling nozzle 31 and the connection port 34 are opened, and the cooling air is supplied to the connection port 34.
Is supplied to the inside of the control panel 20 to cool the inside of the control panel 20.

When the stacker crane 10 leaves the loading station 15 and leaves the origin position after the delivery of the cargo P is completed, the cooling nozzle 31 and the connection port 34 are separated from each other, so that the valves provided in these are closed. Speak.

When the stacker crane 10 finishes loading and unloading of the luggage with respect to the shelves 11 and 12 and returns to the loading station 15, the cooling nozzle 31 is connected to the connection port 34 of the stacker crane 10 in the same manner as described above. In combination, cooling air is supplied into the control board 20. In this way, every time the stacker crane 10 returns to the original position,
The inside of the control panel 20 is cooled.

As described above, in this embodiment, the stacker crane 10 returns to the original position each time the predetermined carrying work is completed, and at this position, the cooling nozzle 3 provided on the ground is returned.
The cooling air is supplied from 1 to the control panel 20. That is, the inside of the control panel 20 is cooled periodically. Therefore, even if the temperature in the warehouse is a high temperature of, for example, about 60 ° or more, the inside of the control panel 20 is effectively cooled, and the normal operation of the electronic circuit in the control panel 20 is ensured.

Further, in this embodiment, since the control panel 20 is arranged on the stacker crane 10, it is not necessary to newly provide a communication system between the control panel 20 and the stacker crane 10, and the control panel 20 itself. Does not require modification of the conventional structure. Further, the cooling nozzle 31 has a connection port 34.
Although it has a structure to open the valve and release cooling air when it is connected to, it does not have a special configuration. Therefore, in the present embodiment, the control panel 20 of the stacker crane 10 can be cooled with a simple configuration, and it can be obtained at a low cost.

In the above embodiment, the cooling air supply source 32
Was provided at a position away from the cooling nozzle 31,
Alternatively, the cooling air supply source 32 may be provided in the cooling nozzle 31.

Further, in the above embodiment, the stacker crane 1
At 0, the control board 20 is cooled by contacting the stopper 24 at the origin and stopped in this state, but the stacker crane 10 does not have to contact the stopper 24 in the stopped state.
