[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article storage facility, and more particularly, to an open position where a moving shelf is formed between adjacent shelves to form a passage for an article transfer machine with respect to those shelves, and the adjacent shelf. Over the closed position close to the shelf, guided by the shelf lower rail below the shelf to make it movable, and the transfer machine lower rail guiding the traveling of the article transfer machine from below in the transfer machine passage, A movable position on a rail of the lower rail for shelves over a predetermined guiding action position in the transfer device passage and a retreat position allowing the moving shelf to move to the closed position by approaching the adjacent shelf. Regarding storage equipment.

2. Description of the Related Art In a storage facility of this type, a lower rail for a transfer machine is arranged on a lower rail for a shelf, so that the lower rail for the transfer machine is continuously connected in a running direction of the article transfer machine. By moving the lower rail for the transfer machine to the retracted position on the rail of the lower rail for the shelf while moving the article transfer machine smoothly while extending the Can be smoothly moved between the closed position and the open position while being guided by a series of lower rails for shelves without obstructing the lower rails for the transfer machine. In order to move the rail between the guide action position and the retracted position on the rail, the following structure has been proposed (see Japanese Patent Application Laid-Open No. 9-100007).

A traveling wheel for rolling the upper surface of the lower rail for shelves while receiving the downward load of the lower rail for transfer equipment is attached to the lower rail for transfer equipment. In addition, one section of a four-section link mechanism assembled in a pantograph shape in plan view was connected to a movable shelf, and a node diagonally related to the node was connected to an adjacent shelf, and attached to each of the remaining intermediate nodes. The pin is engaged with each of the long holes extending in the longitudinal direction of the rail formed on an integral member with the lower rail for the transfer machine.

In other words, with this structure, when the movable shelf is moved from the closed position to the open position, the four-bar link mechanism is deformed toward the side where the two pins are brought closer to each other as the shelf moves. The lower rail for the transfer machine is moved from the retracted position to the guide operation position while rolling the running wheels on the lower rail for the shelf, and conversely, when the movable shelf is moved from the open position to the closed position, As the shelf moves, the four-bar link mechanism is deformed so that the two pins are separated from each other, so that the lower rail for the transfer machine rolls on the lower rail for the shelf while the traveling wheel rolls from the guiding position to the retracted position. Move to storage.

[0005]

However, in the proposed structure, the lower rail for the transfer machine is held at the guiding action position only by the four-bar link mechanism for interlocking with the shelf and the traveling wheels. When the article transfer machine is moved by being guided by the lower rail for the transfer machine located at the operation position, the irregular movement acting on the lower rail for the transfer machine due to the tilt of the article transfer machine or the like. Due to the load, the lower rail for the transfer machine floats up from the lower rail for the shelf, which may make the traveling movement of the article transfer machine unstable.

In view of this situation, the main problems of the present invention are:
While moving the lower rail for the transfer machine between the guide action position and the retreat position on the rail of the lower rail for the shelf, the movement of the article transfer machine caused by the lifting of the lower rail for the transfer machine as described above. This is to prevent the movement from becoming unstable.

In the transfer device passage between the movable shelf in the open position and the adjacent shelf, the article transfer device is stably moved while being properly guided by the lower rail for the transfer device in the guide operation position. Therefore, it is possible to smoothly carry out the work of storing the articles on each shelf and the work of taking out the articles from each shelf by the article transfer machine.

[2] According to the second aspect of the present invention, since the transfer device lifting prevention means for preventing the article transfer device from floating from the lower rail for the transfer device is provided, the lower portion of the transfer device at the guide operation position is provided. When the article transfer machine travels while being guided by the rails, the article transfer machine itself is lifted from the lower rail for the transfer machine due to tilting, etc. Instability of traveling movement can also be effectively prevented, and in combination with the above-described prevention of lifting of the lower rail for the traveling machine, traveling of the article traveling machine in the pathway of the traveling machine is further stabilized. Can be

Since the anti-lifting wheel is provided on the lower rail for the transfer machine, the anti-lifting wheel that rolls with the downward guide surface as a rolling surface when moving is provided. With the contact, the lifting of the lower rail for the transfer machine from the lower rail for the shelf is reliably prevented, and the movement of the lower rail for the transfer machine between the guide action position and the retreat position by the rolling of the lift prevention wheel. Smoothly, the usability of the equipment can be improved.

[4] In the invention according to claim 4, a plurality of the above-mentioned anti-floating wheels are arranged side by side in the moving direction between the guide operation position and the retreat position of the lower rail for the transfer machine. The lifting of the lower rail for the transfer machine when the rail is inclined in the longitudinal direction can be reliably prevented by the contact between the floating prevention wheels of the plurality of wheels arranged in these moving directions and the downward guide surfaces of the lower rail for shelves. Thus, the traveling movement of the article transfer machine in the transfer machine passage can be further stabilized.

[5] In the invention according to claim 5, an upward guide surface is formed on the lower rail for the shelf, and when the lower rail for the transfer machine is moved between the guide operation position and the retreat position, the lower rail for the transfer machine is used. A traveling wheel that rolls on the surface of the upward guide surface while receiving the downward load of the lower rail is provided on the lower rail for the transfer machine. Can be smoothly moved between the guide operation position and the retreat position, and the usability of the equipment can be improved.

[6] According to the invention as set forth in claim 6, when the lower rail for the transfer machine is moved between the guide operation position and the retreat position, the lower rail for the shelf rolls while being sandwiched from both lateral sides. The pair of guide wheels to be provided is provided on the lower rail for the transfer machine, so that the guide action in the state where the pair of guide wheels is sandwiched by the lower rail for the shelf prevents blurring and skew movement, The lower rail can be smoothly moved between the guide operation position and the retracted position, thereby improving the usability of the equipment.

[7] In the invention according to claim 7, in the configuration in which a plurality of the lower rails for shelves are provided in parallel, the lower rail for shelves that operates a moving structure comprising a pair of the anti-floating wheel and the traveling wheel is provided. Since the shelf lower rail for operating the moving structure composed of the guide wheel pair and the traveling wheel is a separate shelf lower rail, the floating prevention wheel, the traveling wheel, and the guide wheel In mounting each pair, for example, the moving structure that acts on each lower shelf rail is simpler than that in which the moving structure composed of all three members acts on a common lower rail for shelves. And small, so that these anti-lift wheels,
The facility can be easily manufactured while obtaining the respective functions of the traveling wheel and the guide wheel pairs.
