Detailed Description of the Invention

[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 for forming a passage between a movable shelf and an adjacent shelf for the article transfer machine with respect to the adjacent shelf, and the adjacent shelf. To a closed position close to the transfer machine, and a transfer machine rail that guides the traveling of the article transfer machine in the transfer machine passage is provided with a predetermined guide action position in the transfer machine passage and the adjacent shelf. The present invention relates to a storage facility that is movable toward a closed position of the movable shelf and a retracted position that allows the movable shelf to move toward the closed position.

[0002]

2. Description of the Related Art A storage facility of this type has a rail of a transfer machine that extends in a continuous direction in the traveling direction of the article transfer machine without interruption so that the article transfer machine travels smoothly while the transfer is performed. By moving the loading machine rail to the retracted position, the moving rack can be smoothly moved between the closed position and the open position without disturbing the loading machine rail.
Conventionally, in order to move the transfer machine rail between the guide action position and the retracted position in accordance with the movement of the movable shelf between the open position and the closed position, the following structure was previously proposed (Japanese Patent Laid-Open No. 9-100007). (See the official gazette).

One node of a four-bar link mechanism assembled in a pantograph shape in plan view is connected to a movable shelf, and a node diagonally related to the node is connected to an adjacent shelf, and attached to each of the remaining intermediate nodes. The pins are engaged with the different long holes extending in the rail longitudinal direction formed in the member integrated with the transfer machine rail, and this structure allows both pins to move as the movable shelf is moved from the closed position to the open position. In a mode in which the four-bar linkage is deformed so that the two move closer to each other, the transfer machine rail is moved back from the retracted position to the guide action position. Then, when the movable shelf reaches the open position, further approach of both pins is blocked by contact between each pin and the inner end edge of each elongated hole, and by this approach blocking,
The movable rack is stopped at the open position, and the transfer machine rail is stopped at the guide action position and held at the guide action position.

On the other hand, as the movable rack is moved from the open position to the closed position, both pins are moved to the side where they are separated from each other.
With the form of deforming the node link mechanism, the transfer machine rail is stored and moved from the guide action position to the retracted position, and when the movable shelf reaches the closed position, further separation of both pins is made to each pin and each long hole. Of the moving rack is stopped at the closed position and the transfer machine rail is stopped at the retracted position and held at the retracted position.

[0005]

However, in the above proposed structure, the transfer machine rail and the movable shelf are stopped at each position only by the relative interlocking action of the shelf and the transfer machine rail, and
Since the transfer machine rail is held at each position, there is a surface lacking the positioning function of the stop position for the movement of the transfer machine rail or the moving shelf, and the transfer machine rail or the moving shelf stops at each position. May cause a non-negligible position error or unstable holding of the transfer machine rail at each position, and these causes, for example, transfer of articles in a transfer machine passage between shelves. This may cause various inconveniences in use, such as a hindrance to the traveling of the machine, the movable rack not being able to be brought into a closed state in which it is properly brought close to the adjacent rack, and a rattling noise is generated.

In view of the above situation, the main problem of the present invention is that by adopting a rational positioning structure, the transfer machine rail and the moving rack can be stopped more accurately at each position, and the moving machine rail can be moved more accurately. The point is that the loading rail can be held more stably at each position.

[0007]

[Means for Solving the Problems]

[1] In the invention according to claim 1, with the movement of the movable shelf to the open position, the transfer machine rail is moved from the retracted position to the guide operation position by contacting the transfer machine rail or a member integrated with the rail. Provided on the moving shelf is a rail returning contact portion for allowing the rail to move to the guide action position by the rail movement by the rail returning contact portion. A fixed contact portion for defining a return position that brings the integrated member into contact with the rail return contact portion so as to sandwich the transfer machine rail or the rail integrated member with the rail return contact portion It is provided on the fixed part.

That is, according to this configuration, the fixed contact portion for defining the return position provided on the support-side fixed portion (typically, the installation floor surface of the equipment), which is a basic fixed portion, is used as a reference. , The transfer machine rail or a member integrated with the transfer machine rail is brought into contact with the fixed contact portion for defining the return position, so that the transfer machine rail is stopped at the guide action position, and at the same time, the transfer machine rail or Since the rail return contact part on the moving shelf side is brought into contact with the fixed contact part for defining the return position via the member integrated with the rail, the moving shelf is stopped at the open position, so the previously proposed facility As described above, irrespective of the supporting side fixing portion for the moving shelf, only by the relative linking action of the shelf and the transfer machine rail, compared to stopping the transfer machine rail or the moving shelf at the guide action position or the open position, Position of stop position for movement of transfer machine rail or moving shelf And ensuring fit, it can be stopped more precisely the transfer machine rail and mobile shelves guiding action position and the open position.

If a plurality of fixed contact portions for defining the return position are arranged in a direction orthogonal to the moving direction of the movable rack in plan view, the transfer machine rails or the movable rack may be temporarily damaged for some reason. Even if it moves diagonally, following the contact with the first of these fixed contact parts for defining the return position,
By making contact with the rest, the high positioning function of each of these fixed abutting parts for defining the return position corrects the skewed posture and allows the transfer machine rail and the moving machine to move. It is also possible to stop the shelf properly in the guiding position or the open position in a proper posture.

Moreover, the movable rack is not directly contacted with the fixed contact portion for defining the return position, but the rail return contact portion provided on the movable shelf and the return position regulation provided on the support side fixed portion. Since the transfer machine rail or a member integrated with the rail is sandwiched between the fixed contact portion for use with the equipment, the equipment proposed above can also hold the transfer machine rail at the guide action position by the sandwiching. Can be more stable than.

From these facts, the stop position error at the guide action position of the transfer machine rail, the stop position error at the open position of the movable rack, and the unstable holding of the transfer machine rail at the guide action position. It is possible to effectively prevent various inconveniences in the use of the equipment due to the deterioration, and to make the storage equipment more excellent in usability.

[2] According to the second aspect of the present invention, with the movement of the movable rack to the closed position, the transfer machine rail or a member integrated with the rail is contacted to retract the transfer machine rail from the guide operation position. A rail storage contact portion to be moved to the position is provided on the moving shelf, and when the transfer machine rail reaches the retracted position by the rail movement by the rail storage contact portion, the transfer machine rail or its rail A fixed contact portion for storing position regulation for bringing the transfer machine rail or the rail integrated member into contact with the rail storage contact portion. It is provided on the support side fixed part.

That is, according to this structure, similarly to the invention described in claim 1, the fixed abutment portion for defining the storage position provided on the support side fixed portion, which is a basic fixed portion, is used as a reference. By bringing the transfer machine rail or a member integrated with the transfer machine rail into contact with the fixed contact portion for defining the storage position, the transfer machine rail is stopped at the retracted position, and at the same time, the transfer machine rail or the transfer machine rail Since the rail storage contact portion on the moving shelf side is brought into contact with the fixed contact portion for storing position regulation through the integrated member with the rail, the moving shelf is stopped at the closed position,
As in the previously proposed equipment, the transfer machine rails and movable shelves are stopped at the retracted position and the closed position only by the relative interlocking action of the shelves and the transfer machine rails, regardless of the support side fixing part for the movable shelf. Compared with the above, the positioning of the stop position with respect to the movement of the transfer machine rail or the movable shelf can be performed more reliably, and the transfer machine rail or the movable shelf can be stopped more accurately at the retracted position or the closed position.

If a plurality of the fixed abutting portions for defining the storage position are arranged in a direction orthogonal to the moving direction of the movable rack in plan view, the transfer machine rails or the movable rack may be temporarily damaged for some reason. Even if it moves obliquely, following the contact with the first of these fixed contact parts for defining the storage position,
By contacting the rest, the above-mentioned high positioning function of each of the fixed contact parts for defining the storage position corrects the skewed posture and allows the transfer machine rail and the moving device to move. It is also possible to stop the shelf properly in the retracted position or the closed position in a proper posture.

Moreover, the movable rack is not directly brought into contact with the fixed contact portion for defining the storage position, but the rail storage contact portion provided on the movable rack and the storage position regulation provided on the support side fixing portion. Since the transfer machine rail or an integral member with the rail is sandwiched between the fixed contact portion for use with the equipment, this sandwiching makes it possible to hold the transfer machine rail at the retracted position as previously proposed equipment. It can be more stable than that.

From these facts, the stop position error at the retracted position of the transfer machine rail, the stop position error at the closed position of the movable rack, and the instability of the transfer machine rail holding at the retracted position are caused. It is possible to effectively prevent various inconveniences caused by the use of the equipment, and to make the storage equipment more excellent in usability.

[3] According to the third aspect of the invention, since the rail return contact portion and the return position defining fixed contact portion are provided, the movement of the movable shelf to the open position is described above. Similarly to the invention according to claim 1, with reference to a fixed contact portion for defining a return position, which is provided in the support side fixed portion for the movable shelf,
The transfer machine rails and movable shelves can be stopped accurately at the guide action position and the open position, and the transfer machine rails can be pinched by the fixed contact portion for defining the return position and the rail return contact portion. Can be stably held in the guiding action position.

Further, in addition to this, since the rail storage contact portion and the storage position defining fixed contact portion are provided, the movement of the movable rack to the closed position is also achieved.
Similar to the invention described above, it is possible to accurately stop the transfer machine rail or the movable rack at the retracted position or the closed position with reference to the fixed contact portion for storing position regulation provided on the support side fixed portion for the movable rack. Further, the transfer machine rail can be stably held at the retracted position by being sandwiched by the fixed contact portion for defining the storage position and the rail storage contact portion.

From this fact, the stop position error at the guide action position and the retracted position of the transfer machine rail, the stop position error at the open position and the closed position of the movable rack, and the guide action position and It is possible to more effectively prevent various inconveniences in using the equipment due to instability in holding the rails of the transfer machine at the retracted position, and to make the storage equipment extremely excellent in usability.

[4] In the invention according to claim 4, when the movable rack moves from the closed position to the open position side by a predetermined distance, the rail returning contact portion is transferred to the transfer machine rail or its rail. Of the transfer rack from the retracted position to the guide action position side. While the required movement distance from the retracted position of the loading machine rail to the guiding action position is smaller, for example, the moving amount of the moving shelf is reduced to the transfer machine rail by the 4-bar linkage mechanism in the previously proposed equipment. Compared to adopting a transmission link structure, it is easy to set the separation distance of the rail return contact part with the transfer machine rail or the member integrated with the rail to a predetermined value when the moving shelf is in the closed position. With a simple structure,
It is possible to cope with the above-mentioned difference in required moving distance between the moving rack and the transfer machine rail, which makes it possible to easily manufacture the linking portion between the moving rack and the transfer machine rail.

Further, since the structure of the linking portion can be simplified as described above, a stop position error of the transfer machine rail or the movable rack and a poor holding of the transfer machine rail due to a malfunction such as a twist of the connection structure can be prevented. In addition, it can be effectively avoided, and the usability of the equipment can be improved more effectively.

[5] In the invention according to claim 5, when the movable rack moves from the open position to the closed position by a predetermined distance, the rail storage contact portion and the transfer machine rail or the rail thereof. Since it is configured to start moving from the guide action position of the transfer machine rail to the retracted position side by contacting the integrated member of FIG. The required travel distance from the guide action position of the transfer machine rail to the retracted position is smaller than the required travel distance to the closed position. Compared to adopting a link structure that reduces the amount of movement and transmits it to the transfer machine rail, the distance between the rail storage contact portion when the movable shelf is in the open position and the transfer machine rail or a member integrated with the transfer rail. Set to the specified value With the simple structure of the above, it is possible to cope with the difference in the required moving distance between the moving rack and the transfer machine rail as described above, thereby facilitating the production of the link portion between the moving rack and the transfer machine rail. You can

Further, since the structure of the linking portion can be simplified as described above, the stop position error of the transfer machine rail or the moving rack and the poor holding of the transfer machine rail due to the operation failure such as the twisting of the link structure can be avoided. In addition, it can be effectively avoided, and the usability of the equipment can be improved more effectively.

[6] In the invention according to claim 6, a lower rack rail for guiding the movement of the movable rack between the open position and the closed position is provided below the rack, whereas the transfer machine rail is Since the lower rails for the shelves are guided and moved on the lower rails for the shelves between the guide action position and the retracted position, the guide by the lower shelves for the shelves allows the transfer machine rails to move along with the movement of the moving shelves. The movement can be smoothed and the usability of the equipment can be further enhanced.

Further, since the lower rails for the shelves for guiding the movement of the movable shelves are used to guide the movement of the transfer machine rails, it is necessary to provide a dedicated guide rail for the transfer machine rails separately from the lower rails for the shelves. In comparison, the structure can be simplified and the facility can be easily manufactured.
