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 Conventionally, as a special automatic warehouse, for example, about 60
In a high-temperature environment of $ C, there is a type in which a stacker crane is configured to load and unload cargo to and from a rack. Such an automatic warehouse, for example, stores steel materials and the like that have just been manufactured in a steel mill. Since the temperature in the warehouse is high, the temperature in the control panel mounted on the stacker crane tends to be high. Therefore, it is necessary to cool the control panel in order to ensure the performance of the electronic circuit provided in the control panel.
However, at present, there is no small cooling device capable of sufficiently cooling the control panel in a limited space such as on a stacker crane under a high temperature environment of about 60 ° C. It has to be placed in.

[0003]

However, if the control panel originally provided on the stacker crane is arranged on the ground, control data is transmitted between the control panel and the stacker crane. The necessity of providing a communication system causes a problem 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 configuration.

[0005]

SUMMARY OF THE INVENTION A control panel cooling device for a stacker crane according to the present invention is provided with a cooling nozzle at a predetermined position on a traveling path and a cooling nozzle on a control panel on the stacker crane. the connection port capable of binding to form the, stack
When the crane comes to a predetermined position, the cooling nozzle is connected to the connection port and supplies cooling air into the control panel.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a side view showing a cooling device of a control panel of a stacker crane according to one embodiment of the present invention, and FIG. 2 is a plan view showing a schematic configuration of an automatic warehouse having the cooling device of FIG.

The stacker crane 10 travels along a traveling route provided between the shelves 11 and 12 to carry out loading and unloading of goods. That is, the stacker crane 10
Between 1 and 12, the vehicle runs while being guided by the rail 13 on the ground and the guide rail 14 on the ceiling side, and conveys the package P received from the loading station 15 to the shelf 11,
The luggage P stored in the predetermined position 12 or taken out of the shelves 11 and 12 is transferred to the loading station 15. The loading station 15 has shelves 11, 1
2 is provided on one end side, that is, on the origin side of the traveling route of the stacker crane 10, and temporarily places the load P.

In the stacker crane 10, the elevator 1
6 is supported by the 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 package P to the shelves 11, 12 or the loading station 15. The stacker crane 10 is equipped with a control panel 20 for controlling the operation of the lift 16 and the slide fork 19, and a motor 23 for running the stacker crane 10.

A stopper 24 is provided at the origin of the traveling route of the stacker crane 10. Stacker crane 10
Returns to the origin every time a predetermined transport operation is completed, and stops at this origin position by contacting the stopper 24. 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 this embodiment, the cooling device has a cooling nozzle 31 provided near the origin, and a cooling air supply source 32 provided at a position 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 panel 20 on the top 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.

The cooling nozzle 31 and the connection port 34 are provided with valves (not shown), respectively. Each valve is
The valve is opened in a state where the cooling nozzle 31 and the connection port 34 are connected to each other, whereby the cooling air 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. Is done. Each valve is closed when the cooling nozzle 31 and the connection port 34 are open to each other. Therefore, in this state, no cooling air is discharged from the cooling nozzle 31 and the connection port 34 is also closed.

The operation of the present embodiment apparatus 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 connection port 3 between the cooling nozzle 31 and the control panel 20 is stopped.
And 4 are combined. Therefore, at this time, each valve of the cooling nozzle 31 and the connection port 34 is opened, and the cooling air is
From the control panel 20 to cool the inside of the control panel 20.

When the delivery of the package P is completed and the stacker crane 10 leaves the loading station 15 and leaves the origin position, the cooling nozzle 31 and the connection port 34 are separated, and the valves provided for these are closed. Give a valve.

When the stacker crane 10 finishes loading and unloading the cargo on 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. The cooling air is supplied into the control panel 20 by the connection. Thus, every time the stacker crane 10 returns to the home position,
The inside of the control panel 20 is cooled.

As described above, in this embodiment, the stacker crane 10 returns to the origin position each time a predetermined transfer operation is completed, and at this position, the cooling nozzle 3 provided on the ground is provided.
1 is configured to supply cooling air to the control panel 20. That is, the inside of the control panel 20 is periodically cooled. Therefore, even if the temperature in the warehouse is as high as 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 disposed on the stacker crane 10, there is no need to newly provide a communication system between the control panel 20 and the stacker crane 10, and the control panel 20 itself is not required. Need not modify the conventional structure. The cooling nozzle 31 is connected to the connection port 34.
Although it has a structure to open the valve when it is connected to and discharges cooling air, it does not have a special configuration. Therefore, in this embodiment, the control panel 20 of the stacker crane 10 can be cooled with a simple configuration, and can be obtained at low cost.

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

In the above embodiment, the stacker crane 1
In the state of 0, the control panel 20 is cooled by contact with the stopper 24 at the origin, and the stacker crane 10 may not be in contact with the stopper 24 in the stopped state.
