Abstract

PURPOSE:To remove the need to conduct test operation by operating a controller one by one by a worker as before and conduct simply test operation at the time of transfer rack provision or the like by providing a test operation mode to make each transfer rack conduct repetition action automatically. CONSTITUTION:By operating a changeover switch, the operation mode of each transfer rack is switched over to a test operation mode, and an open command to open empty passages P0, P6 on the side parts of blocks B1, B2 is transmitted to the controllers 30-36 of respective blocks B1-B6, and the whole of the blocks B1-B6 is moved in arrow X2 and arrow X1 directions, then the empty passages P0, P6 are opened. Also an open command to open a passage 5 is transmitted to the controller 36 of the block B6, and the block B6 is moved in the arrow X2 direction, and the passage P6 is closed, and instead the passage P5 is opened. Likewise, passages P4, P3, P2, P1 are opened in order. The operation of these transfer racks are repeated automatically until the test operation mode is turned OFF.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile rack system including a plurality of mobile racks. In particular, the present invention relates to a mobile rack system that enables easy test operation of the mobile rack.

[0002]

2. Description of the Related Art Conventionally, in a factory or a warehouse, a moving rack system capable of efficiently storing luggage in a small space has been used.

FIG. 8 is a front view of a moving rack in such a moving rack system.

In FIG. 1, the movable rack is provided with a movable carriage 1 movable along a traveling rail R and a luggage storage rack 2 which is erected on the upper portion of the movable carriage 1. 30 ~
36 is a controller for automatic operation of shelves,
It is attached to the front of the luggage storage rack 2.

Such a movable rack is, as shown in FIG.
Plural pieces are arranged side by side on the traveling rail R. The movable shelves arranged in this manner are moved by operating the controller 3. An interlock is provided between the movable shelves.

In such a mobile rack system, in order to determine whether or not the mobile rack operates normally, a trial run is performed when the mobile rack is installed.

[0007]

The following problems have been encountered in the test run of the above-mentioned conventional moving rack system.

The test run was performed by the operator operating the controller 3 of each movable rack one by one. Therefore, there is a problem that the procedure is complicated and takes time.

An object of the present invention is to solve the above problems and to provide a mobile rack system which can easily perform a trial run of the mobile rack.

[0010]

To achieve the above object, the present invention provides a system comprising a plurality of movable shelves,
It is configured to have a test operation mode in which each movable rack is automatically and repeatedly operated.

[0011]

Since the movable rack system of the present invention has the above-mentioned structure, it has the following operational effects.

That is, since the mobile rack system is provided with a test operation mode in which each mobile rack is automatically and repeatedly operated, it is not necessary for the operator to operate the controller one by one as in the conventional case. .

Therefore, according to the mobile rack system of the present invention, there is an effect that the trial run of the mobile rack can be easily performed.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic plan view for explaining a trial run of the mobile rack system according to the present invention. The same parts as those in the conventional example are designated by the same reference numerals.

The mobile rack system of this embodiment has a test operation mode in which each mobile rack is automatically and repeatedly operated.
In this embodiment, two test operation modes are provided. One is to move forward or backward the whole moving rack to test whether empty passages are formed on the side of the moving rack, and the other one is to form a passage between each moving rack. It is to test whether it is done.

The switching to the trial operation mode is performed by a changeover switch (not shown) or a terminal of a computer by remote control.

When the mode is switched to the trial operation mode, the movable rack stops the automatic operation and performs the trial operation.

Next, the operation of the movable rack in the above-described test operation mode will be described.

In FIG. 1, block B1 to block B
Reference numeral 6 is a movable rack, and P0 to P6 are reference numerals indicating passages or positions where passages should be formed. Each mobile shelf has arrows X1 and X2
It can move in any direction.

First, the trial operation mode for forming an empty passage on the side of the movable rack will be described.

When a changeover switch (not shown) is operated to change the operation mode of the movable rack to the trial operation mode,
An open command for opening the empty passage P0 to the side of the block B1 is issued by the controllers 30 to 3 of the blocks B1 to B6.
6, the entire blocks B1 to B6 move in the direction of arrow X2 in the figure.

As a result, as shown in FIG. 2, the empty passage P6 formed on the side of the block B6 is closed,
Instead, an empty passage P0 opens to the side of the block B1.

Next, an empty passage P6 is provided on the side of the block B6.
Is transmitted to the controllers 30 to 36 of the blocks B1 to B6, and the entire blocks B1 to B6 move in the arrow X1 direction in the figure. As a result, the passage P
0 is closed and passage P6 is opened instead.

In the operation of the movable rack for forming the empty passage P0 or P6 as described above, the trial operation mode is turned off.
Is automatically repeated until.

Next, a test operation mode in which a passage is formed between the movable shelves will be described.

When a changeover switch (not shown) is switched to the test operation mode, an open command for opening the passage P5 is transmitted to the controller 36 of the block B6, and the block B6 moves in the direction of arrow X2 in the drawing. As a result, FIG.
, The passage P6 is closed and, instead, the passage P5
Opens. Then, an open command for opening the passage P4 is transmitted to the controller 35 of the block B5, and the block B5 is opened.
5 moves in the direction of arrow X2 in the figure. As a result, as shown in FIG. 5, the passage P5 is closed and the passage P4 is opened instead. After that, in the same manner, the passages P3, P2, P
1, P0 is opened.

After that, in the state where the passage P0 is open, an open command for opening the passage P1 is transmitted to the controller 30 of the block B1, and the block B1 is indicated by an arrow X1 in FIG.
Move in the direction. This closes the passage P0 and opens the passage P1 instead. After that, an open command for opening the passage P2 is transmitted to the controller 32 of the block B2, and the block B2 moves in the direction of arrow X1 in FIG. This causes passage P1 to be closed and passage P2 to be opened instead. After that, in the same manner, in order, the passages P3, P4, P
5, P6 is opened.

The above-described operation of the movable rack for forming the passages P0 to P6 between the movable racks is automatically repeated until the trial operation mode is turned off.

According to the mobile rack system of this embodiment described above, the test run of the mobile rack can be easily performed.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention.
