BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic warehouse installed, for example, in a factory, in which goods are stored using framed shelves, and goods are taken in and taken out using a loading/unloading tool of a loading/unloading device.

0002

2. Description of the Related Art For example, an automatic warehouse comprising shelves and a cargo handling device has been provided with a structure as shown in Japanese Utility Model Application No. 61-7105.

That is, as shown in FIG. 7, trusses 100 are erected at predetermined intervals in the front and back and left and right, and arms 101 are connected from the sides of these truss 100 to the side of the adjacent truss 100. It constitutes a shelf 103 having a plurality of pool parts 102 in the direction. On the front side of the shelf 103, there is a cargo transfer device 1 for loading and unloading the pallet 105 on which the cargo 104 is placed.
06 is installed.

This cargo delivery device 106 includes a traveling body 111 supported by a floor rail 107 via wheels 108 and guided by a ceiling rail 109 via rollers 110, and a traveling body 111 supported and guided by the traveling body 111. It is composed of an elevating table 112, an ejecting/extracting mechanism 113 provided on the elevating table 112 so as to be movable laterally.

Therefore, according to the above-mentioned conventional example, the running action of the traveling body 111 on a fixed path along the front surface of the shelf 103, the lifting/lowering movement of the lifting platform 112, and the loading/unloading mechanism 1
Due to the combined movement of 13 with the lateral movement, shelf 1
03 and the cargo handling device 106.
The cargo 104 can be delivered via the terminal 5.

[0006] At that time, the cargo delivery device 10 is
6 Power supply unit 11 for supplying power and transmitting/receiving signals to the side
4 are arranged along a certain path near the ceiling rail 109, and a current collector 11 is installed on the upper part of the traveling body 111.
5 is provided. In addition, in order to allow the cargo delivery device 106 to travel to the target location, a detection device for travel control is provided at the bottom of the traveling body 111, and a detection device is installed on the floor near the floor rail 107 so as to face this detection device.

After the loading/unloading device 70 is installed between the frame shelves 1 in this manner, the position of the current collector 80 is corrected. That is, the movable bracket 82 is moved relative to the fixed bracket 81, the current collector 85 is brought into contact with the rail portion 45, and then fixed by the fixture 83.

In the automated warehouse configured as described above, the frame shelves 1 are Pallets (cargoes) 11 are loaded and unloaded between the storage unit 14 and the loading/unloading device 70.

The loading/unloading device 20 operates as described above.
The power supply and control signal transmission and reception are smoothly performed by the current collector 85 of the current collector 80 slidingly contacting the rail portion 45 of the power supply device 22 . At this time, since the power supply part is located at the lower part of the passage, the dust generated by the sliding contact will immediately fall on the floor or float in a small area, and will not deteriorate the surrounding environment. In addition, maintenance and management can be performed from the floor side after the operation is stopped, and since the power supply device 22 and the detected device 23 are located in the dead space created at the lower front of the frame shelf 1, it may cause problems such as obstacles to walking. Maintenance and management can be performed without any problems occurring.

[0031] In the above embodiment, the length of the rail unit 20 is determined according to the length of the fixed path 69, and when the fixed path 69 is long, it is manufactured by being divided into a plurality of parts, which are connected at the installation site. , and when the constant path 69 is short, a single one is used.

In the above embodiment, the rail unit 20 places the mounting piece 60A of the bracket 60 on top of the receiving piece 62A of the receiving bracket 62, and both pieces 60A.
, 62A are connected via bolts and nuts 63 to fix them between both frame shelves 1, but in this case both frames 40 and 50 are connected by abutting them laterally against the support column 2 side. It may be a format.

[0033]

According to the present invention having the above configuration, the rail unit in which the power supply device and the detected device are arranged on both sides and the rail is arranged in the center can be assembled at the manufacturing factory before shipping. By placing the rail unit between the pillars on both sides at the bottom of the aisle, the rail and power supply device can be integrated and installed at a predetermined position relative to the frame shelf, making the overall construction easier and faster. It can be done easily and inexpensively.

In this arrangement, the power supply device and the detected device can be located in a dead space created at the lower front of the frame shelf where they will not interfere with walking, etc.
Therefore, it is possible to easily walk in the passageway, and the object to be detected is not stepped on when walking in the passageway, so that traveling control can always be performed accurately.

Since the power supply device and the current collector are installed near the floor, maintenance and management can be carried out easily and safely from the floor. The collected dust immediately falls onto the floor or floats in a small area, so the surrounding environment can always be kept in good condition.
