Abstract

PURPOSE:To make operation simple, to simplify a system, and to make it possible to shift a dispersal position, by a method wherein, when the work putting in and out is finished, a desired passage is opened or rack equipments are automatically shifted in a dispersal position, since one switch operated and timers interlocked with its switch operation are equipped. CONSTITUTION:After the work putting in and out is finished, timers for restricting travel to the left (TR1-TR4) and to the right (TF1-TF4) are started to operate at this point of time when the reset is operated. When a passage selection switch (PB3) is operated at the place where rack equipments are in equally dispersal position, for instance, a break contact (C3) in a circuit is opened and a make contact (sf) is closed. Since right traveling relays (RF1 and RF2) for the rack equipments (A and B) and left traveling relays (PR3 and PR4) are operated, motors (M1 and M2) are revolved clockwise, and motors (M3 and M4) are revolved counterclockwise. The rack equipments (A and B) are thus traveling to the right and the rack equipments (C and D) are traveling to the left. When the rack equipment (A) traveling to the right reaches a wall (11) on the right, a limit switch (LS1) goes off by being pushed, a relay (RF1) is reset, and a make contact (rf1) is opened. The current to a motor (M1) is thus shut off, and then the rack equipment A is stopped.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention comprises a plurality of shelving devices, and when not in use, the shelves are spread out so that there is space between adjacent shelving devices.
The present invention relates to an electric movable shelving device that moves the shelving devices when storing and storing articles to form a space between desired shelving devices with a width corresponding to a working path.

A dense movable shelving device in which a working passage is formed on the storage surface side of the desired shelving device for storing and storing has been conventionally provided (for example, Japanese Patent Publication No. 52-50582
(see publication).

In addition, when not in use, in order to improve ventilation between each shelving device, after completing the loading/unloading operation, the shelving devices are moved to the spread-out position by operating a switch to create a gap between each adjacent shelving device. Mobile shelf devices have also been provided in the past (see, for example, Japanese Patent Publication No. 56-45602).

[Problems to be Solved by the Invention] By the way, with the above-mentioned device, there are cases in which the shelving device is immediately unfolded after the completion of the dispensing work in one aisle because there is no next dispensing, and in cases where the shelving device is opened immediately after the completion of the dispensing work in one aisle, and when the shelf device is opened for the subsequent dispensing work. In some cases, the next desired passage may be opened. Therefore, in the past, two types of switches were provided, one for spreading and one for resetting, or a changeover switch was provided instead of using both, to avoid operational complexity. The problem was that there was no.

In addition, in order to move the shelving device to the unfolded position, the unfolded position is determined in advance, and the limit switch of each shelf device is engaged with a structure on the floor, etc. to move each shelf device to the normal position. This poses problems such as being mechanically complicated and making it difficult to vary the unfolding position.
