Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to movable shelving equipment installed in a narrow space in a warehouse, for example, a fixed shelf, and a movable shelving system that is arranged parallel to the fixed shelf and that can move toward and away from the fixed shelf. The present invention relates to movable shelf equipment including movable shelves.

Conventional movable shelf equipment has a movable shelf that can be moved in the direction between the fixed shelves between a pair of fixed shelves, and a push button switch for starting travel is installed on each movable shelf. It was designed to move movable shelves. By the way, when installing movable shelving equipment, pillars of a building or the like may exist within the installation space. In such cases, conventionally, in order to avoid pillars, etc., the only option was to install multiple movable shelving equipment. However, in such a system, all the movable shelves must be equipped with operating equipment, which is uneconomical, and each movable shelf must be operated separately, which is extremely troublesome.

The present invention solves the above-mentioned conventional drawbacks. Even if pillars or the like exist in the installation space, the present invention can be installed while avoiding them, and is more economical and easy to operate compared to the case where multiple movable shelves are installed. The purpose of the present invention is to provide mobile shelf equipment that is extremely easy to move.

In order to achieve the above object, the movable shelf equipment of the present invention includes a fixed shelf and at least one movable shelf that is arranged parallel to the fixed shelf and can approach and move away from the fixed shelf. A plurality of rows are provided in a direction perpendicular to the direction of movement of the movable shelves, and one set of movable shelves is provided in each row, and a running start operation switch is installed on one of the set of movable shelves. The entire set of movable shelves can be moved by operating a switch.

According to this configuration, since fixed shelves and movable shelves are provided in multiple rows, it is possible to avoid pillars, etc., and to install the operating equipment only on one of the set of movable shelves. Furthermore, the entire set of movable shelves travels simply by operating the operating switch for starting travel, which is economical and extremely easy to operate compared to the case where a plurality of movable shelf facilities are provided.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 1 and 2, reference numerals 1 and 2 are a pair of fixed shelves facing each other at a predetermined interval. (5 in this example) movable shelves 3~
7 are arranged parallel to the fixed shelves 1 and 2. Each of the shelves 1 to 7 has a plurality of divided storage spaces 8 in the vertical and horizontal directions. Each of the movable shelves 3 to 7 is mounted on a rail 9 provided on the floor side via wheels 10, and can be moved individually by a motor mounted thereon. The fixed shelves 1 and 2 and the movable shelves 3 to 7 are arranged in a plurality of rows (two rows in this embodiment) in a direction perpendicular to the direction between the fixed shelves, and the pillar 11 is located between them. That is, the fixed shelves 1 and 2 and the movable shelves 3 to 7 are provided in sets of two, avoiding the pillars 11, and one of the movable shelves 3 in the set has a main control panel 12.
However, a sub-control panel 13 is installed on the other movable shelf 3 and all the movable shelves 4 to 7 of the other set. These control panels 12 and 13 are for controlling movement, and are connected to each other by a cable 14 for power supply and signal exchange. One of the movable shelves 3 to 7 of each set includes a sub-operation box 15.
are installed respectively, and a main operation box 16 is installed on one of the set of movable shelves 3. These operation boxes 15 and 16 are for moving the movable shelves 3 to 7, and are connected to the control panels 12 and 16.
13 by a cable not shown. Each of the movable shelves 3 to 7 is provided with a reflective photoelectric switch that is inclined at a predetermined angle with respect to the movable shelf traveling direction and serves as a travel restriction detector 17 for detecting the adjacent shelves 1 to 7 and regulating their travel. It is installed.

Next, the operation will be explained. Now, as shown in FIG. 1, a space 18 is formed between the movable shelves 4 and 5.
It is assumed that this space 18 is used to load and unload cargo into and out of the divided storage spaces 8 of the movable shelves 4 and 5 using a forklift vehicle, a crane, or the like. Next, as shown in FIG. 2, when it is desired to form a space 18 between the shelves 2 and 7 and to load and unload cargo into the storage space 8 of the shelves 2 and 7, each set of movable shelves 5 and 7 By operating a running start operation switch (not shown) of a sub-operation box 15 installed on one side of the movable shelves 5 to 7, the movable shelves 5 to 7 are sequentially moved toward the fixed shelf one set at a time. Note that the operation switch for starting running is composed of, for example, two push button switches for each running direction. If the vehicle is operated in the wrong direction, the vehicle will of course not travel because the travel restriction detector 17 is activated. In this way, for example, both movable shelves 5 start running at the same time by operating the running start operation switch of the sub-operation box 15 installed on one side of the movable shelves 5. Since they do not always move at the same speed, stopping operations are performed separately for each. In other words, both movable shelves 5
When the movable shelf 4 moves toward the fixed shelf 1 and approaches the movable shelf 4 by a predetermined distance (for example, 200 mm), the traveling restriction detector 17 installed on each movable shelf 4 detects this individually, and as a result, the movable shelf 5 A traveling stop signal is supplied to the sub-control panel 13 of the movable shelves 5, and each movable shelf 5 stops individually. Therefore, both movable shelves 5 stop at a predetermined distance from the movable shelf 4 regardless of variations in their running speeds. Similarly, the movable shelves 6 and 7 sequentially move toward the fixed shelf 1 side, and a space 18 of a predetermined width is formed between the shelves 2 and 7.

Note that it is clear that a specific circuit for controlling the movement of the movable shelves 3 to 7 can be appropriately designed using relays, electronic circuits, etc., so a description thereof will be omitted.

Furthermore, although the above-mentioned movable shelf equipment was not explained in the embodiments, it goes without saying that it is equipped with various safety devices.

Further, in the above embodiment, a pair of fixed shelves 1,
Although an example in which two shelves are provided has been described, only one of them may be a fixed shelf, and all the others may be movable shelves.

As explained above, according to the present invention, fixed shelves and movable shelves are provided in multiple rows, so it is possible to avoid pillars, etc., and to install operating equipment only on one of a set of movable shelves. All you have to do is install it, and the whole set of movable shelves will move just by operating the operation switch to start the movement, so it is economical and extremely easy to operate compared to installing multiple movable shelves. It is.
